Description

Technical Field

[0001] The invention relates to an oral cleaning tool, in particular to a tooth irrigator with a stepless water content adjustment device for cleaning teeth, interdental spaces and oral cavity. Background Art

[0002] Due to aging, pathological reasons and other reasons, it is easy to cause gum atrophy and widening of tooth spaces, which can easily lead to food residue. If not cleaned in time, on the one hand, it will produce bad breath, and on the other hand, it will easily lead to various dental diseases and oral diseases, especially periodontitis.

[0003] In view of this situation, various products such as dental floss, interdental brushes, water floss and the like are currently developed on the market for users to choose from. In particular, water floss products are widely used oral cleaning products on the market due to their convenience in use and good cleaning effect.

[0004] The working principle of water flossing is to use the impact force of a high-speed water column ejected under a certain pressure to clean the teeth and mouth. Therefore, the high-speed water column will inevitably have a very large impact on the teeth, gums, etc. inside the mouth, and each person has a different tolerance to the impact force of the water column according to their own oral conditions. Therefore, during use, each person needs to choose a different water column impact speed according to their own tolerance. The current method commonly adopted by water flossing is to process in different gears, allowing users to select different gears. Although this method is simple to operate, it is often impossible to select the most suitable water column impact force for an individual that takes into account both cleaning effect and comfort.

[0005] In order to overcome the shortcomings of the prior art and allow users to select the most comfortable water column impact force, it is necessary to develop a dental irrigator that can continuously adjust the water volume. Summary of the invention

[0006] The dental irrigator with a stepless water content adjustment device of the present invention realizes stepless and continuous adjustment of the water output by arranging a stepless water volume adjustment device on the dental irrigator, so that the user can select the most comfortable water output and water column impact force according to his or her own feelings during use.

[0007] The tooth irrigator with a stepless water content adjustment device of the present invention is characterized in that: the tooth irrigator with a stepless water content adjustment device 100 comprises a spray head 1, a spray gun 2, a control switch 3, a container 4, a water pipe 5 and a stepless water content adjustment device 6;

[0008] A. The spray head 1 is arranged at the front end of the spray gun 2; the control switch 3 can control the spraying of the fluid in the spray gun 2; the fluid in the container 4 is connected to the spray gun 2 through the water pipe 5;

[0009] B. The stepless water volume regulating device 6 comprises a regulating switch 61, a controller 62 and a signal output device 63; regulating the regulating switch 61 can continuously regulate the signal output by the controller 62, thereby continuously regulating the pressure of the fluid sprayed from the spray gun 2.

[0010] Since the regulating switch 61 of the stepless water volume regulating device 6 can continuously adjust the signal output by the controller 62, the signal output by the output device 63 can be continuously changed, and the pressure of the fluid sprayed by the spray gun 2 can be continuously adjusted by continuously adjusting the output signal of the controller 62. When using the tooth irrigator, the user can adjust the water pressure to the most comfortable level according to his or her tolerance and preference, which greatly enhances the cleaning effect and comfort of the tooth irrigator during use.

[0014] The knob-type regulating switch can continuously adjust the output signal of the potentiometer 62-1, such as a voltage signal, by rotating the knob 61-1. The output signal of the potentiometer 62-1, such as a voltage signal, is the input signal of the control chip 62-2. By adjusting the input signal of the control chip 62-2, the output signal of the control chip 62-2 can be continuously adjusted, such as the output voltage, current, power, frequency, pulse waveform, etc. The signal output by the control chip 62-2 can control the water pressure sucked out by the water suction device 7 or the pressure increased by the booster device 41-1 on the liquid in the pressure container 41. By continuously adjusting the signal output by the control chip 62-2, the pressure of the fluid sprayed from the nozzle 1 can be continuously adjusted.
