Replacing the battery of an oral toothbrush b. How to properly care for electric toothbrushes, DIY repair tips

Health oral cavity It is impossible without quality care, and a toothbrush is the first assistant in this. The quality of cleaning with its help depends on the type of paste and correct execution manipulation. All on the advice of dentists more people switching to electric toothbrushes. They clean plaque better and thoroughly treat the oral cavity in hard-to-reach places.

Types of Braun Oral-B electric toothbrushes

Testing of Oral B Braun electric toothbrushes showed their effectiveness in combating the formation of tartar, soft coating, the spread of caries. Special attachments help to cope with changes in the shade of enamel from tobacco, coffee, tea, and other stains. Polishing attachments eliminate bad taste and feelings of “dirty” teeth.

Such devices are not suitable for everyone, so when choosing, it is important to get advice from a dentist. Good doctor would not recommend electric brushes to patients with sensitive enamel, wedge-shaped defect of teeth, bleeding gums, artificial teeth. The presence of a pacemaker or a tumor in the oral cavity is also a contraindication.

Electric brushes require a power source - batteries or rechargeable batteries. The type of battery determines the power and rotation of the head and the ability to take the device on a trip. Experts advise choosing a device based on the desired functionality.

Mechanical

The cleaning element in mechanical models is a round head with bristles. Depending on the capabilities of the brush, it is capable of rotating in a circular pulsating or reciprocating mode, performing from 5,000 to 30,000 combined movements per minute.

The negative aspects of Oral B Professional mechanical devices are their low power compared to sonic and ultrasonic devices, and the heads move in only one direction. This reduces the capabilities of the device, but does not become a barrier for people who do not need special dental care.

Sonic and ultrasonic

Oral b Braun sound models contain a high-frequency generator of sound vibration waves. The head vibrates at up to 18,000 movements per minute. At the same time, the oral cavity is well cleaned of plaque, and sound vibrations weaken the connection of bacteria with the enamel surface. When cleaning with such models, no special skills are required, and even children can master the process.

In ultrasonic devices, cleansing is based on the active influence of ultrasound on bacteria that are present on the gums and teeth. High frequency waves penetrate 4 mm. deep into the bristles, allowing you to clean interdental space, gingival grooves, other hard-to-reach places. Models of ultrasonic brushes remove soft pigment plaque. During operation, the device increases the temperature of surrounding tissues by 1 degree. This promotes active penetration of the healing components of the paste.

No brush can cope with tartar and hard plaque. To remove them, use special techniques in the dental hygienist's office.

Recharging the device

This article talks about typical ways to solve your issues, but each case is unique! If you want to find out from me how to solve your particular problem, ask your question. It's fast and free!

Included with the battery device is Charger with two-way charging plug. It is plugged into a socket for electric shavers, or using an adapter into a regular socket. Charging is carried out inductively, without connecting the handle and the device metal elements. Thanks to this, the charging base can be placed wherever it is convenient, including in the bathroom.

The best option for owners of electric brushes is to keep them charged all the time between uses. When first used, the manufacturer recommends fully charging the battery (within 12-16 hours), and then completely discharging it. Then fully charge the battery again and keep it in working condition. This procedure will extend the life of the battery. It is recommended to repeat it once every six months.

When do you need to change batteries?

When it is not possible to connect to a power supply, a full charge of the electric brush should be enough for a week. A decrease in the functionality of the battery indicates that it is exhausting its resource and will soon need to purchase a new one. After how many months is the first replacement needed? Typically, at least 2 years pass from the start of operation to the first battery change. Signs your Oral B battery needs to be replaced:

The charge is enough for 1-2 teeth brushing;
the quality of oral cleansing decreases;
the brush does not vibrate as actively;
at the wrong moment the device turns off, although it was recently charging.

These signs may indicate other malfunctions of the device. It is better to re-read the instructions again, which describe non-working situations. If the brush is more than two years old, probable cause faults in the battery.

After three months of use, it will, of course, be almost discharged, but its charge will be quite enough to operate for a certain period of low-power load. Try connecting it, observing the polarity, for example, to an electronic one with a liquid crystal display, or to a homemade LED flashlight with a Joule Thief type converter. In any case, place the battery not inside the load, but outside: despite the fact that the brush is sealed from the inside, by the end of its service life the seal is broken, and the first corrosion appears.

After this, pull out the plastic frame with the motor. To do this you will need miniature pliers. Wire cutters will not work. Unhook the two latches that secure the frame to the brush body, then pull it out towards you.

On the frame you will find a simple changeover switch and a motor. Separate them from each other. If they are wet, wipe them dry and then dry them.

If you decide to give your electric starter, the switch and motor will come in handy. The first one is equipped with dielectric pushers of any design. Then install these parts on stands, and place clamps on them for connecting to other circuits. All that remains is to connect a 10-volt two-anode zener diode in parallel to the engine (or one of two zener diodes connected in series cathode to cathode). This is necessary to protect children's fingers from bursts of self-induction. Remember that this motor is designed for a voltage of 1.5 V.

Hand brush in 2019

Daily Cleaning teeth is the main and most important prevention of caries. For this procedure to be as effective as possible, toothbrush must be selected very carefully, in accordance with age and type of enamel sensitivity.

From year to year, electric toothbrushes are becoming more common, and large quantity people are switching from using mechanical devices to electrical, more advanced gadgets. This is explained not only by the fact that such devices cope with their task better and more efficiently, but also by the fact that today they have become quite cheap. Of course, you still need to pay more for an electric brush than for a manual one, but its properties fully pay for themselves. On the modern market, such a device is represented by a lot of brands and an even larger variety of models, which, in turn, are distinguished by a wide range of characteristics and technical differences. The choice can stop at the simplest products at a price of $10, as well as those that cost more than $100 or more.

Of course, given that today toothbrushes have become “smart” and electric, such devices require some care. And so today we want to look at information about how toothbrushes should be cared for and repaired.

Caring for Electric Toothbrushes

To begin with, we suggest considering information about how to care for such important hygienic devices. To ensure that your brush serves you for as long as possible, and the cleaning effect remains at the same quality level, we recommend that you familiarize yourself with the tips described below:

Carry out systematic rinsing of the brush. Both before and after the cleaning procedure, it is necessary to rinse the brush under running water. This way you can remove various particles of debris from the bristles. You don’t have to worry about the safety of the device, since modern brushes are moisture resistant and are not exposed to water;
After brushing your teeth, always check the charge level of your toothbrush so that the next time you brush your teeth you won’t get a “pleasant” surprise in the form of a dead battery;
Always keep the device in vertical position. It is recommended to dry the brush only in a vertical position, placed in an empty, dry glass;
Change attachments at least once every few months. Just like mechanical toothbrushes, electric ones also require periodic replacement. Fortunately, this does not mean purchasing a new device, but only purchasing a spare brush head. By making such a replacement in a timely manner, you can count on the fact that the effect of brushing your teeth with an electric brush will not decrease, and the attachment itself will not be a breeding ground for germs (after all, when using attachments for more than 3 months, they begin to accumulate a lot of bacteria);
When changing attachments, it is necessary to perform a cleaning procedure, which involves thorough rinsing under running water. Apply heat treatment(like boiling) is not recommended, it disrupts the structure of the bristle fibers.

Using a sterilizer

One more important aspect When caring for an electric brush, you need to use devices such as a sterilizer (also called disinfectors). This is a small device in the form of a case or cup, which serves to perform a more thorough procedure for sterilizing a toothbrush. Thanks to the use of an ultraviolet sterilizer, you can be completely sure that the brush will be completely sterile and ready for use after each sterilization procedure.

Some toothbrushes are sold with such devices included, but this only applies to more expensive gadgets. If you want to purchase a disinfectant separately, this is a fairly rational solution, but you should be prepared for the fact that such a device can cost the same as a budget electric brush - from 10 to 20 dollars (and some models even higher).

How to charge an electric toothbrush

The next one is very important question, concerning the operation of the electric shield, is the correct use of the device’s battery resources and extending its life. Many consumers who systematically use electric gadgets to brush their teeth mistakenly believe that the best solution is to charge the device daily, simply by keeping the brush on charge the entire time the gadget is not in use. Of course, such a hypothesis is doomed to failure, and such actions can only lead to rapid failure of the battery and the need to replace it. In fact, brush battery care should be different, and below we will look good advice from specialists.

It is worth noting that some popular manufacturers of electric brushes today assure their consumers that recharging their devices is impossible. That is, if you leave the brush always installed on the charging base, there will be no problems with it, the charge will reach the maximum, and the device will automatically stop charging. However, this is not the most practical solution, so it is not recommended to use it.

In addition, it is important to note the following nuances:

A full charge of the brush should be enough to use the device for regular cleaning for a week. If you begin to observe a decrease in the functionality of the battery, this means that it has gradually begun to exhaust its resources and will soon require replacement;
To fully charge the brush, depending on the manufacturer and model, it can take from 12 to 16 hours.

Before charging the device for the first time, it is recommended to carefully study the instructions, which must contain information about proper charging. If we talk about the most popular devices manufactured by Philips or Braun Oral-B, then such brushes can be stored on the charging station all the time, however, if you keep the brush in the bathroom, it will simply be inconvenient to constantly keep it plugged into an outlet. Therefore, we recommend you the most best option– charge once a week, but regularly check the device’s charge level to avoid problems with premature battery discharge.

How to disassemble an electric toothbrush

Finally, we want to pay attention to the procedure for disassembling toothbrushes different manufacturers. After all, replacing the battery is not the only operation that brush users may need to perform during their operation. Therefore, it is important to know how to properly disassemble this gadget.

The following instructions must be followed:

Check the device and make sure it is turned off.
Remove the nozzle.
Remove all brush elements that are attached without additional funds, like screws.
Check the loose parts and unscrew them if possible.
If we're talking about on how to disassemble an electric toothbrush Braun brush, Philips or similar brands, then the electrical base with the board and brush controller is installed in the housing without using any screws for fastening. Take pliers or tongs, and with their help, securely fixing the rotating element of the brush, pull it towards you. The base of the brush is installed in the body and secured with a rubber ring; with some effort, you can get it out.
The brush can be considered disassembled.

All other elements of the base can be disassembled as simply as possible and do not require separate instructions. You may need a small shaped screwdriver to remove the screws. After disassembling the brush, you can:

Replace diodes;
Replace the battery;
Replace buttons and other damaged elements;
Remove and replace the motor.

After execution necessary operations with EZShch, its assembly is carried out in the reverse order.

What to do if the battery fails

If you have been using your electric brush for more than one year, you have probably noticed that its battery no longer lasts for long periods of time, as it did before. Battery wear is absolutely normal phenomenon, and you can fight it. The ideal solution is to buy a new battery and install it instead of the used one.

Even though the battery is by default a non-removable part of the brush design, replacing it is not that difficult. For this purpose you can use with the following instructions:

Remove any removable structures, such as the brush head, from the brush.
Find the device components attached to the case with small screws and unscrew them.
Disassemble the device.
Reach the battery and remove it.
Remove the element from the Ni-MH battery that connects it to the contacts in the battery compartment. This may require the use of a soldering iron. The dismantling procedure is extremely simple - touch the heated tip of the soldering iron to the element, wait until it becomes hot and frees itself from tin.
Take the battery you previously purchased as a replacement.
Similarly, using a soldering iron and tin, attach the Ni-MH cell to the new battery.
Return the battery to the compartment and reassemble the toothbrush.
Check the functionality of the device with a new battery.

This way you can replace the battery in your dental Oral-B brush Triumph and many other models, as well as manufacturers such as Philips. As for directly purchasing replacement batteries, today you can buy such elements on well-known sites, such as:

Ebay;
Aliexpress;
GearBest.

Now that you know how to care for, charge and repair toothbrushes, you will be able to not only use this device correctly so that it serves you as long as possible, but also independently remove and replace its elements if they fail.

To maintain the oral cavity healthy condition people enjoy by different means for care. But the quality depends on many factors: the initial condition of the teeth, the brand of toothpaste, and the right brush.

Some people use , which refers to . It helps control pressure on the gums and carry out hygiene in hard-to-reach places. Sometimes there is a need to repair or replace the battery, and to do this you need to know how to disassemble a Braun Oral-B toothbrush.

How to disassemble: stages

Braun Oral-B comes with a charger for activation. But the model can work without a network, in which case it will function without recharging for a week.

You can replace the battery yourself using these instructions:

Disconnect all removable parts.
Insert the device into the charger and twist it 15-20 times until you hear a click, which indicates the case is opening.
Unscrew the small security screws.
Carefully remove all internal components.
Unsolder the contacts and remove the battery.
Connect the contacts to the new battery.
Insert the block into place and try to turn on the device. If it starts to work, reassemble the device completely.
If the assembled model does not work, you need to put it on a short-term charge. But for this you will need: a new battery, a small screwdriver, a soldering iron.

When purchasing an original toothbrush, the kit includes:

Charger;
Toothbrush;

Analysis of a mechanical model is no different from sound and ultrasonic. The differences concern:

power;
cost;
appearance;
number of combined movements.

Analysis is practically no different from Braun Oral-B, the only difference is appearance and the place where the contacts are soldered when removing the battery.

What repairs can be done

Most often, several types of repairs are performed on Braun Oral-B electric toothbrushes.

battery replacement;
button repair.
changing the nozzle.

Where to get the battery

It is safest to buy a battery from Braun service centers.

Battery for dental Oral-B brushes also often purchased from:

Aliexpress;
Ebay;
Taobao.

When to change the battery

Like any other battery-powered device, the brush will break down within a few years. There are several signs that indicate that the Oral-B battery needs to be replaced:

The device works, but is not as active as before.
The effectiveness of oral care during normal activities decreases.
A full charge only lasts for one cleaning.
The device may turn off at any time.

If the Braun Oral-B electric brush is over 2 years old, then all of the above signs indicate a malfunction of the battery.

The device needs to be changed when it completely breaks down, but the nozzles should be changed once every three months. It is also necessary to look at the condition of the head and bristles, since everyone individually cares for the oral cavity. Accordingly, one person can use the attachment for 5 months, and another for 2.

Rechargeable toothbrushes have been clinically proven to remove plaque better than regular toothbrushes. Although they are relatively expensive, with proper care these brushes will last at least 5 years. The brush heads are easy to change, allowing the whole family to share one power handle and still have their own toothbrush.

How does it work

The cleaning action is provided by the orbital movement of the brush head attached to the end of the head holder barrel. The hollow barrel includes a miniature gearbox in its design and is placed on the drive spindle in the handle. The handle, which is made in the form of a non-separable unit, contains an electric motor, an electronic control unit and a rechargeable battery. Some handles have an external switch slider. In other models, the switch button is covered with a flexible rubber-like cover.

Charger

Each brush is equipped with a charger on which the brush is installed to recharge the battery. The charger is also an isolated monobloc design - charging is done inductively and there are no metal contacts electrically connecting the handle and the charger. Therefore, the rechargeable toothbrush can be used completely safely in the bathroom, and the device is equipped with a two-pole plug for electric shavers. If there is no outlet for an electric razor, then the charger can be plugged into any outlet in the house through the appropriate adapter. The charger body may have a compartment for replaceable brush heads.

Battery charge

When charging your new toothbrush for the first time, place it on the charger and the indicator light will illuminate to indicate that it is charging. Leave it to charge for the amount of time indicated in the instructions (usually 16 hours), then remove the brush from the charger and let it run until it runs out of charge.

Rice. 2 Charging an electric toothbrush

Place the brush back on the charger and charge for 16 hours or as directed by the manufacturer. To keep the battery in good working order, it is recommended to repeat this procedure approximately every six months. For optimal use, it is best to keep the brush on the charger in constant charging mode - the battery will not take “too much” charge.

Reciprocating motion

To increase the cleaning effect, the latest models have added a reciprocating component to the orbital movement of the brush head.

Two minute warning

Cordless toothbrushes have a built-in timer that, after 2 minutes, causes the brush to work intermittently for several seconds - this is a signal that the minimum recommended duration of brushing has passed. The motor will then operate normally again so that cleaning can continue. On some models, you can select the driving speed to avoid discomfort at sensitive teeth and gums.

CLEANING THE CORDLESS TOOTHBRUSH

After brushing your teeth, rinse the brush under running water while it is on. Rinse the brush head and holder barrel with water and dry with a paper towel or napkin.

About once a week, remove the brush head and rinse it all the way through the tail to rinse inner part. Wipe the drive shaft and handle with a damp cloth. If you have hard water, do this more often to avoid mineral deposits.

Rice. 3 Cleaning an electric toothbrush.

If black plaque begins to accumulate on your brush, do not use toothpaste with a whitening agent. This generally harmless discoloration is caused by bleach deposits in the crevices of your toothbrush.

The deposit may not be noticeable under the slide switch of older models. To clean this area, move the slider back until it disengages and scrub off the residue with a nail brush under running water. When all parts are clean, you need to press the switch and move it forward so that it falls into place. Be careful not to turn the engine backwards.

From time to time, unplug the charger from the outlet and wipe it with a damp cloth. If the device has a unit with a compartment for storing brush heads, then remove it and rinse it under running water. Dry the unit thoroughly before reinstalling it.

Spontaneous turning on of the toothbrush

Water got inside

A crack in the body or a torn rubber band covering the switch button may allow water to enter the brush. This defect cannot be repaired.

Green indicator does not work

When the brush is placed on the charger, the green indicator light should light up. Make sure the charger plug is plugged into the outlet and check the following:

No power supply

If other devices in the same circuit have stopped working, check the panel: there is a blown fuse or a tripped circuit breaker or RCD.

The presence or absence of voltage can be shown by a non-contact tester if you touch the base protrusion on which the toothbrush is placed.

Rice. 4 Bring the non-contact tester to the base protrusion

If it looks like the charger isn't working, then you'll almost certainly have to buy a whole new set.

BRUSH DOESN'T WORK

Water gets inside

If the brush is dropped, its body may burst and water will get inside.

Putting too much force on the spindle when brushing your teeth can damage the seal and cause it to leak.

The rubber coating on the power button may tear and allow water to enter.

If any of these types of damage occurs, the rechargeable toothbrush is likely beyond repair.

Battery won't charge

The battery being charged may be damaged. First test the charger using a non-contact tester (see above). If there is voltage, ask the service center if it is possible to replace the toothbrush itself.

Faulty charger

See above..

Time and pressure indicators

Brushes are made with colored bristles, which should fade after a certain time, and this is a signal that it is time to change the head. Dentists recommend in any case changing the brush head after three months of use and even earlier if the bristles are bent or deformed.

Rice. 5

Bent bristles are a sure sign of excessive pressure on the brush; Only light guiding pressure is required. The latest models are made taking this circumstance into account. This could be a spring-loaded head that reacts to excessive force, or intermittent operation, etc.

THE MAIN THING IS SAFETY

Batteries should not be disposed of with household waste. If they fail, return them to the manufacturer's service center, where they will be safely disposed of.

Good luck with the renovation!
