Oral cleaner using compressed air

Abstract

The present invention relates to an oral cleaner. An oral cleaner, according to the present invention, comprises an air injection unit for injecting high-pressure air; a cleaning solution tank in which a cleaning solution is stored; an acceleration unit, connected to the cleaning solution tank by means of a first tube body and to the air injection unit by means of a second tube body, for, when high-pressure air is supplied from the air injection unit, withdrawing the cleaning solution from the cleaning solution tank by means of the pressure differential and then injecting same; a nozzle unit which is connected to the acceleration unit by means of a tube body and through which the cleaning solution injected by means of the high-pressure air can be injected on the teeth; and a switch unit for injecting or blocking the cleaning liquid by controlling the air injection unit.

Description

technical field [0001] The present invention relates to an oral cleaner using compressed air, and in more detail, relates to a device capable of effectively removing calculus between teeth and foreign matter in the oral cavity by spraying cleaning liquid toward teeth by compressed air at high speed. Background technique [0002] In general, oral cleaners use a method in which a cleaning liquid is pumped and supplied to a nozzle so that the cleaning liquid is sprayed from the nozzle into the oral cavity through a single injection port. At this time, a large amount of cleansing liquid is sprayed into the oral cavity not as a spray but as a water column. Therefore, there is a problem that the user needs to clean the oral cavity while continuously discharging a large amount of cleansing liquid. [0003] In addition, there is a problem that the cleaning liquid is sprayed while maintaining a jet of water, so if the jetting port is shaken due to external impact or vibration, etc. s...

AI Technical Summary

Problems solved by technology

At this time, a large amount of sprayed cleansing liquid is sprayed into the oral cavity not in the form of a spray but in the form of a water column. Therefore, there is a problem that the user needs to clean the oral cavity while continuously discharging a large amount of cleansing liquid.

[0003] In addition, there is a problem that the cleaning liquid is sprayed while maintaining a jet of water, so if the jetting port is shaken by external impact or vibration, etc. so that the jetting direction deviates from the teeth, the jet of water is jetted to the gums, tongue, hard palate, etc., thereby It is difficult to spray evenly into the mouth, and when the water column comes into contact with the inside of the mouth, it will cause discomfort. In the case of gum disease, repeated local impacts will be concentrated on the wound site, which may worsen the disease

[0004] In addition, Korean Patent Application No. 10-2011-83691 (name: Toothbrush) discloses a toothbrush that can brush the teeth in the oral cavity, but has the problem of not being able to clean the inside of the oral cavity sufficiently.
