Air pressure oral cavity washing equipment

Abstract

The invention discloses air pressure oral cavity washing equipment. An air pump is connected to a liquid container through an air pipe; the liquid container is connected to the nozzle through a liquidpipe; a valve is mounted at the joint of the liquid container and the liquid pipe; the air pump sucks air from the air inlet, exhausts the air from the exhaust port and injects the air into the liquid container through the air pipe and an one-way valve; a suction pipe is mounted on one side of a container shell; the one-way valve, a pressure test hole and a liquid outlet are arranged on the upperend surface of a container cover; an air pipe inlet is formed in the upper end of the one-way valve; and a liquid in the liquid container is pressed out from the liquid inlet by pressure, passes through the suction pipe, the liquid outlet and the liquid pipe and is sprayed out from the nozzle. The liquid is driven by air pressure to be sprayed out, large impact force and high explosive force areachieved in the initial stage of liquid spraying, waste ineffective flow is avoided, and flushing liquid is saved; the impact force of the sprayed liquid can be adjusted linearly or in a multi-gear mode, and the rhythm of flushing water flow cannot be affected; and only when the air pump works, noise is generated, so that vibration and noise in the using process are reduced.

Description

technical field [0001] The invention belongs to the technical field of tooth cleaning appliances, in particular to an air pressure oral irrigating device. Background technique [0002] With the improvement of the quality of life, the increase in the types of diet, the food is becoming more and more refined, and more and more periodontal diseases plague people. Medical research believes that bacteria in dental plaque can cause various periodontal diseases. Therefore, removing plaque is very important for oral health. Brushing your teeth doesn't do a good job of removing food particles between the teeth, which build up and cause plaque. Generally, cleaning the teeth with dental floss or toothpicks can help people remove food residues in the gaps between the teeth and reduce the generation of dental plaque. However, due to the various structures and complex shapes of interdental spaces, dental floss and toothpicks cannot effectively remove plaque and may damage periodontal ti...

Problems solved by technology

But at this time, not only the momentum of the water flow is reduced, but also the frequency of the water flow is changed, which greatly changes the sense of rhythm during flushing;

[0006] Moreover, due to the use of a piston-type water pump, when the user uses the handheld device, he will feel strong vibration and harsh noise at the same time;

[0007] And due to the law of small initial momentum of the piston water pump, the water flow with small momentum in front of it cannot wash the gap between the teeth during use. In order to get a better flushing effect, users often continue to flush, consuming water (or liquid medicine) Larger, both wasteful and bulky for liquid containers
