Smart flosser solution
Teeth flosser (also known as water flosser) is a tool that uses pulsed water impact to clean teeth and interdental gaps. There are mainly portable and desktop, and the general flushing pressure is 0 to 90psi.
1. Classification of dental flosser scheme design
1. Stamping fixed frequency dental flosser
Traditional electric flossers have been on the market for a long time. In terms of product structure, the AC 220V fixed-speed motor is used to drive the water pump to generate constant pulse water flow, and the pulse rate is fixed at about 1200 times/min. AC motors generate high heat during operation. Users should pay attention to the reminders given to users on the use time of different models when using them. Do not use for more than 2 minutes for a single use, and do not use for more than 5 minutes every 2 hours, so as to avoid overheating of the machine and cause use. Fault.
2. Household frequency conversion dental flosser
"The pulse frequency of the variable frequency dental flosser is adjustable within the range of 1320-1500 times per minute. At the same time, the water flow can also be adjusted. Generally speaking, the higher the vibration frequency, the better the cleaning effect. The reason why the dental scaler used in the clinic uses ultrasonic frequency. The frequency conversion water flow dental flosser has a massage effect on the gums at low pressure through the combination of frequency and pressure, and the cleaning effect is enhanced at high pressure."
The product structure of the frequency conversion dental flosser adopts a high-power DC motor, and the pulse frequency is controlled by a computer chip to realize the frequency conversion control of the water flow. The motor has no heat and can be used continuously. At the same time, the internal circuit adopts a DC low-voltage design, and the working voltage is lower than 16V, which is a safe voltage below 36V, ensuring the safety of electrical appliances in the watery environment around the bathroom washstand.
3. Portable flosser
With the development of dental flosser technology, a portable rechargeable dental flosser has appeared. The main unit uses a rechargeable battery as a power source. When using it, it only needs to be charged, and it can be used for about one to two weeks. Due to the small size of the main body of the portable dental flosser, there is no wire on the body, and no external power supply is needed during use. It is suitable for daily use, and is also suitable for use outside or in places without power supply. For the orthodontic population (orthodontics with braces), since the food on the braces needs to be cleaned after each meal, the portable flosser is more suitable for them, because it can be used in unlimited occasions. For more users, they prefer The reason for the portable flosser is that it does not need to be plugged in when using it, and it is more convenient to use without the long wires of the desktop flosser.
2. The technical principle of the dental flosser program
1. Design principle of flosser
Just as people know that using a high-pressure water gun can easily clean the car, etc., the water flow of appropriate pressure has long been proven to be effective in cleaning people's teeth and oral cavity. On the basis of the impact force of the water flow itself, first, the water flow can be sprayed and impacted in an appropriate pulse form, or more air bubbles can be brought into the water flow to have a similar vibration and impact effect. 2. Add some additives with different functions to the water flow, such as adding fine hard and heavy sand particles to form countless high-speed "bullets", or adding some surfactants to increase the cleaning function, etc. The impact cleaning ability of the water column is also related to the size of the water column There are relationships. 3. By changing the frequency of the water flow pulse, the best combination with the pressure can be achieved. For example, the professional teeth cleaning machine in the dental clinic has a high frequency of more than 20,000 times. From the principle of using frequency vibration to clean objects, the higher the frequency, the better the cleaning effect.
There are two main sources of water pressure needed for flossers:
1) Use its own electric pump to generate water pressure;
2) Directly use the pressure of tap water. Therefore, according to the structure, dental flossers can be mainly divided into two categories: electric dental flossers and faucet dental flossers. The structure of electric dental flossers mainly includes an electric water pump, water storage tank, and nozzle. The structure of the toothbrush mainly has a connecting device and a nozzle with the faucet.
2. Functional requirements of dental flosser program
1. power section. In consideration of personal safety and device heating, the 12V low-voltage DC external power adapter is selected to ensure absolute safety, stable and reliable power, and the power adapter will not heat up significantly after long-term use.
2. Mechanical part. The main issues considered in the design of the mechanical part: the selection of the water pump requires that the water pump is safe and reliable; the water pressure is moderate and adjustable; the noise is small, light and easy to install; it is decided to choose a small 12V vane water pump.
1) Cord charging base. The base is a wireless charging transmitter, and the external wire input part is a USB interface;
2) The flosser machine itself. The internal circuit board needs a wireless charging receiving module, and the circuit board drives a small motor of model 280 to work through the control circuit. The battery is a 3.6V Ni-MH battery. The fuselage contains the switch key and function switch key and 4 LED lights. The display of the LED lights respectively represent: a, the motor rotates rapidly; b. the motor rotates at a low speed; c. the motor rotates intermittently (pulse); d, the wireless charging indicator (in low battery, the red light flashes to indicate the charging demand. The charging process The middle red light is always on. When it is fully charged, it is displayed as a green light. It is usually off). When the small motor is working, press the function switch button to switch the speed of the small motor. Its working motor is the same as the small motor, and can switch between large, small and pulse speeds;
3) Sprinkler head. This part is only a mechanical nozzle, without any wiring part;
4) Toothbrush head. Contains a vibrating cup motor, a small control circuit. During use, when the water spray head is replaced with a toothbrush head, the 280 small motor inside the fuselage stops working, and the internal vibration motor of the toothbrush head works. Its working motor is the same as the small motor, and can switch between large, small and pulse 3 speeds.
3. Necessity of tooth flosser program development
At the junction of the teeth and the gums, there is a sulcus about 2 mm deep that surrounds the teeth but is not attached to the teeth, called the gingival sulcus. This is the most important link to the root of the tooth. But the junction is the most likely to hide dirt and dirt, and it is the place that is most likely to cause tooth and gum disease. The gingival sulcus and the gap between the teeth are the two most difficult places to clean. Some studies have pointed out that "as many as 40% of the tooth surface cannot be cleaned with a toothbrush". While flossing (or a toothpick) can remove surface buildup, microscopically, uneven tooth surfaces can still be unclean. Bacterial growth only needs an extremely thin layer of nutrient film, and the harmful effects of the remaining dirt film still partially exist. In principle, the pressure water flow that is both powerful and capable of drilling into holes is the most ideal way to clean the oral cavity. According to the research of relevant institutions in the United States, the pressure water column can rush into the gingival sulcus to a depth of 50-90%. The pressure water column can not only clean all kinds of crevices, holes and uneven surfaces, but also achieve microscopic thorough "cleaning" instead of macroscopic rough "cleaning". In addition to the function of cleaning the teeth and mouth, the water flow can also massage the gums, promote the blood circulation of the gums and enhance the disease resistance of local tissues; at the same time, it can also eliminate bad breath caused by poor oral hygiene.
4. Instructions for use of dental cleaner
one. Features of Electric Multifunctional Pulse Scaler
The electric multi-functional pulse tooth cleaner uses ultra-fine high-pressure pulse water column to rinse and clean food residue, tooth stains, tartar and plaque on the surface of teeth, gingival sulcus and deep between teeth. It has the following characteristics:
1. Improve bad breath. Food residues are easily embedded between the teeth, which are fermented by bacteria to produce odor. Using the dental flosser can remove food debris in time and reduce bad breath.
2. Improve bleeding gums. Gingivitis is easy to cause gum bleeding, and the pulsed water column cleans the gum wound, which is conducive to wound healing.
3. Aids in teeth cleaning for brace wearers. Whether it is a wearer of a fixed aligner or a removable aligner, due to the large number of attachments, food is easier to embed and it is difficult to clean with a toothbrush, but a thorough cleaning effect can be achieved by rinsing with water.
4. Helps clean dental implants and dentures in the mouth. There is a certain gap between the implant and the gums. The longer the time, the gap between the fixed bridge and the gums will become larger and larger. The food dirt in these gaps can only be thoroughly cleaned by washing with water.
5. Cleaning the mouth with water can also prevent tooth decay and reduce the occurrence of stomach problems.
two. The structure and function of the electric multi-functional pulse tooth cleaning device

8. Rotate nozzle (0～3600). Press down to pull out or install the nozzle, and turn it left and right to adjust different angles to clean teeth and oral cavity.
9. Retractable water hose (1 meter). Connect the outlet pipe of the water pump to the nozzle.
10. Handle. It can be inserted into the base to fix when not in use.
3.Flosser Instructions for Use
1. Before use, put water or a cleaning solution with a fungicide into the water tank. Then plug the 12V DC external power adapter into the connection socket on the back of the base.
2. Press the button switch on the base, the indicator light is on, the water pump starts to work, but the nozzle does not spray water.
3. Pull out the handle, rotate the nozzle, aim the replaceable nozzle at the teeth or between the teeth, toggle the five-level water pressure adjustment switch on the handle from small to large, select the appropriate water pressure, and the nozzle will start spraying water along the gums and sticking Move the nozzle back and forth between the teeth, and wash away the rice residue and dirt on and in the teeth with water. It can also fully clean the entire mouth and tongue. During the whole washing process, if the five-speed switch is placed in the first gear, the nozzle will stop water, and the switch will be turned off quite dry, but at this time, the water pump will continue to work.
4. After one person washes, press the key switch on the base again, the indicator light goes out, and the water pump stops working. Depress the swivel head, pull out the nozzle, and replace it with another person's special nozzle. As long as there is enough water in the water tank, you can continue to wash your teeth according to the methods described in 2 and 3. If the water tank is short of water, it can be replenished at any time.
5. After all the washing is completed, disconnect the button switch, pull out the adapter plug, unplug the 12V DC external power adapter, then pour out the remaining water in the water tank, cover the water tank cover to prevent dust, and clean the nozzle with clean water or alcohol for future use. Use it next time.
4.Precautions
The parts of the electric multi-function pulse toothwasher are made of non-toxic plastic. When using it, handle it with care so as not to break it. The selected 12V DC external power adapter is stable and reliable, and it will not heat up significantly after working for a long time, so it is safe and guaranteed. When selecting a five-gear pressure switch, it must be opened from small to large, and a suitable gear should be selected, and high gear must not be used at the beginning. The first gear switch does not produce water, and it can be used as a temporary water shut-off when in use. When washing, since water will flow out at any time, it is required to open the mouth into a trumpet shape. The nozzle rinses along the gaps of the teeth one by one to completely remove all the stains between the teeth. After the teeth are cleaned, rinse the tongue and palate by the way, which can maintain the hygiene and health of the entire oral cavity.
