Parsing the braun oral b. Spontaneous activation of the toothbrush. When to change batteries
Health oral cavity impossible without quality care, and a toothbrush in this is the first assistant. The quality of cleaning with it depends on the type of paste and correct execution manipulations. On the advice of dentists more people switch to electric toothbrushes. They are better cleaned from plaque, carefully treat the oral cavity in hard-to-reach places.
Types of electric toothbrushes Braun Oral-B
Electric Dentist Testing Oral brushes B Braun have shown their effectiveness in the fight against the formation of tartar, soft patina the spread of caries. Special nozzles help to cope with a change in the shade of enamel from tobacco, coffee, tea, and other stains. Polishing tips eliminate bad taste and feelings of "dirty" teeth.
Not everyone is shown such devices, therefore, when choosing, it is important to get the advice of a dentist. good doctor will not recommend electric brushes to patients with sensitive enamel, wedge-shaped defect teeth, bleeding gums, artificial teeth. A contraindication is also the presence of a pacemaker, neoplasms in the oral cavity.
Electric brushes need a source of energy - batteries or accumulators. The power and nature of the rotation of the head, the ability to take the device on a trip depends on the type of battery. 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 possibility 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 low power compared to sonic and ultrasonic devices, the movement of the heads in only one direction. This reduces the capabilities of the device, but does not become an obstacle for people who do not need special dental care.
Sonic and ultrasonic
The Oral b Braun sound models contain a high frequency sound waveform generator. The head vibrates at up to 18,000 strokes per minute. At the same time, the oral cavity is well cleaned of plaque, and sound vibrations weaken the bond between bacteria and the enamel surface. When cleaning with such models, special skills are not 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 the interdental space, gingival sulcus, and other hard-to-reach places. Models of ultrasonic brushes remove soft pigment deposits. During operation, the device raises the temperature of surrounding tissues by 1 degree. This contributes to the active penetration of the healing components of the paste.
with tartar and hard coating no brush can do it. To remove them, special techniques are used in the office of a dental hygienist.
Recharging the device
This article talks about typical ways to solve your questions, but each case is unique! If you want to know from me how to solve exactly your problem - ask your question. It's fast and free!
The battery-powered instrument is supplied with a charger with a two-way plug for recharging. It is plugged into an outlet for electric shavers, or using an adapter to a regular outlet. Charging is carried out inductively, without metal elements connecting the handle and the device. Thanks to this, the charging base can be placed anywhere convenient, including in the bathroom.
The best option for owners of electric toothbrushes is to keep them on charge all the time between uses. When using for the first time, the manufacturer recommends fully charging the battery (within 12-16 hours), and then fully discharge it. Then fully charge the battery again and keep it in working condition. Similar procedure prolong battery life. It is recommended to repeat it every six months.
When do batteries need to be changed?
When it is not possible to connect to the power supply, full charge electric brush should be enough for a week. A decrease in battery functionality indicates that it is exhausting its resource, and a new one will soon be required. After how many months is the first replacement necessary? It usually takes at least 2 years from the start of operation to the first battery change. Signs that the battery in your Oral B needs to be replaced:
- the charge is enough for 1-2 brushings;
- the quality of cleaning the oral cavity decreases;
- the brush does not vibrate so actively;
- at the wrong moment, the device turns off, although it was recently charged.
These signs may indicate other malfunctions of the device. It is better to re-read the instructions again, where non-working situations are described. If the brush is more than two years old, probable cause malfunctions in the power supply.
Over the years of operation, a bad thing happened to her - the charge was enough for one time.
I found a manual on the Internet. I bought the battery on ebay for 850 rubles. Came in 10 days. On Aliexpress it was the same, for 400 rubles.
First of all, remove the ring from the top of the brush.
Then plug in the charger lower part and spin while it spins. As soon as it becomes worse / slips (there is a plastic screw) - pull the white part down.
We take out the insides by snapping off the two white latches. 
We unscrew the display (you need a torx), a Chinese set of various kinds of screwdrivers comes in handy 
We take out the spring 
Unsolder 2 terminals of the old battery 
Forming conclusions 
We solder a new one, fasten the display.
The brush says that there is no charge. After charging (the manual says about a day of charging), everything will show as it should. 
Let's see how bad the old Akum is. There are no charge / discharge graphs, only pictures. Because there is a curved software for it only under Windows, and even then it gets sick. It was easier to take a photo.
Since I removed the brush from charging, I discharge the old battery with imax - I get almost 600 mAh. There is no capacity on it, 2100mAh is indicated on the new one, we will think that the old one is of a similar capacity. 
Charged with a current of 0.2A for a long time. 
Discharged with a current of 1A (it seems to me that there are more currents in the brush, but oh well) 
There are 800 mAh left when discharged to 0.8 V. IMHO, it does not discharge so deeply in the brush.
After three months of use, it will, of course, be almost discharged, but its charge will be enough to work for some period of a low-power load. Try connecting it with correct polarity, for example, to electronic ones with a liquid crystal indicator, 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 life, the seal is broken, and the first corrosion appears.
After that, pull out the plastic frame with the engine. To do this, you will need miniature pliers. The pliers won't fit. Unhook the two latches that secure the frame to the brush body, then pull it out towards you.
On the frame you will find the simplest toggle switch and motor. Separate them from each other. If they are wet, wipe them dry and then dry.
If you decide to give your electric kornstruktor, the switch and the engine will be very handy. First supply dielectric pushers of any design. Then install these parts on stands, and place clamps on them for connecting to other circuits. It remains to connect a 10-volt two-anode zener diode in parallel with 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 such a motor is designed for a voltage of 1.5 V.

Daily brushing of teeth is the main and most main prevention caries. To make this process as efficient as possible, toothbrush must be selected very carefully, in accordance with the age and type of sensitivity of the enamel.
In 2011, I was lucky enough to snatch a Braun Oral-B Triumph Professional Care 9000. I walked around it in circles for half a year, but the price of $100 was above my psychological maximum. Then bam and $50!!! I'm in shock, the toad too. I had to take. The brush is really great. I would like this in childhood - there were fewer holes in my teeth. I buy replacement tips on eBay. Naturally not original. Only once got slag. Usually the spring is made of stainless steel, but here they slipped it out of steel. I threw out the whole set.
Until 2016, there were no problems with the brush. In 2017, the battery began to fail. Threshed weakly, the charge went quickly. So I made it to 2018. Last month started glitches with the display of the charge. Shows 100%, turn on 0%. It's time I thought. If you drive in a model on eBay, then the prices for the battery are hell and Israel. Thank you at least the size is indicated. Asked the right question to Google and got the answer:
standard sizes of batteries and accumulators
It turned out that the Braun Oral-B Triumph Professional Care 9000 costs a Ni-Mn 4/5A 1.2 volt battery with a nominal capacity of 2200mAh. Prices on eBay immediately became adequate. Bought two PKCELLs for $5. Checked on iMax-B6. 2700mA is poured, 2200mA is drained at a discharge current of 800mA. Killed showed 1500mA.

Installed on the board
Cordless 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 easily interchangeable, allowing the whole family to use one electromechanical handle, and each one has their own toothbrush.
How does it work
The cleaning action is provided by the orbital movement of the brush head fixed on the end of the shaft of the head holder. The hollow barrel includes a miniature gearbox in its design and is put 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 supplied with a charger, on which the brush is installed to recharge the battery. The charger is also an insulated one-piece design - charging is done inductively and there are no metal contacts electrically connecting the handle and the charger. Therefore, the cordless toothbrush can be used perfectly safely in the bathroom, and the appliance is equipped with a two-pole plug for electric shaver sockets. If there is no outlet for an electric shaver, then the charger can be plugged into any outlet in the house through the appropriate adapter. A compartment for interchangeable brush heads can be provided in the charger housing.
Battery charge
When charging a new toothbrush for the first time, place it on the charger and the indicator light will come on to indicate that it is charging. Leave it to charge for the time indicated in the instructions (usually 16 hours), and then remove the brush from the charger and let it work until it is completely charged.
Rice. 2 Charging an electric toothbrush
Put 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 recharging mode - the battery will not take “too much” charge.
reciprocating motion
To improve the cleaning effect in the latest models, a reciprocating component has been added 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 a few seconds - this is a signal that the minimum recommended brushing time has passed. The motor then runs normally again so you can continue cleaning. On some models, you can select the driving speed to avoid discomfort at sensitive teeth and gums.
CLEANING THE CORDLESS TOOTHBRUSH
Rinse the brush under running water after brushing your teeth. Rinse the brush head and holder shaft with water and dry with a paper towel or tissue.
About once a week, remove the brush head and flush it through the tail section to flush inner part. Wipe the drive shaft and handle with a damp cloth. If you have hard water, do this more often to avoid mineral salt deposits.
Rice. 3 Cleaning an electric toothbrush.
If black deposits start to build up on your brush, don't use whitening toothpaste. This generally harmless discoloration is caused by bleach deposits in the crevices of the toothbrush.
The coating may not be visible under the slide switch of older models. To clean this area, move the slider back until it disengages and scrub off the buildup with a nail brush under running water. When all parts are clean, you need to press the switch and slide it forward so that it falls into place. Be careful not to flip the engine backwards.
Unplug the charger from the outlet from time to time and wipe it with a damp cloth. If your device has a brush head storage unit, remove it and rinse under running water. Dry the unit well before reinstalling it.
Spontaneous activation of the toothbrush
Water got inside
A crack in the housing or a torn rubber covering the switch button can allow water to enter the brush. This defect cannot be repaired.
Green indicator not working
When the brush is placed on the charger, the green indicator light should come on. Make sure the charger is plugged in and check the following:
No power
If other devices in the same circuit have stopped working, check the shield for a blown fuse or tripped circuit breaker or RCD.
The presence or absence of voltage can be shown by a non-contact tester if it touches the base ledge on which the toothbrush is placed.
Rice. four Bring the non-contact tester to the base ledge
If the charger doesn't seem to be working, then you'll almost certainly have to buy a whole new set.
BRUSH DOES NOT WORK
Water gets inside
If the brush is dropped, its body may burst and water will get inside.
Too much force on the spindle when brushing your teeth can damage the seal and cause it to leak.
The rubber cover on the power button may break and expose water to the inside.
With any of these damages, the cordless toothbrush is most likely beyond repair.
Battery not charging
The rechargeable battery may fail. First test the charger with a non-contact tester (see above). If there is tension, 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 changing the brush head after three months of use anyway, 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 with this circumstance in mind. This may be a spring-loaded head that responds to excessive force, or intermittent operation, etc.
THE MAIN THING - SAFETY
Batteries must not be disposed of with household waste. In case of failure, return them to the manufacturer's service center, where they will be safely disposed of.
Good luck with the repair!
