JPH02299651A - Pocket-size jet washing device - Google Patents

Abstract

PURPOSE:To enhance washing effect by injecting a compressed fluid mixture from a perforated nozzle by utilizing the difference between the compression ratios of water and air generated when the same pressure is applied to water and air. CONSTITUTION:A washing water cartridge 2, a battery 3, a micromotor 4 and a water pressure pump part 5 are mounted and an air mixing nozzle 6 mixes air with water to increase the jet pressure from a perforated nozzle by the difference between the compression ratios of water and air and imparts pulsation to jet pressure. At the time of use, a washing perforated nozzle part 11 is slid upwardly and the massage effect to the gum is obtained by the strong pulsated jet stream from an extremely fine perforated nozzle 6 and washing effect is also obtained by the ultrasonic waves generated when air bubbles disappear. By making this washing device pocket-size, said washing device is always carried during a travel, duty or going out and can be easily used without being limited to the oral cavity.

Description

[Detailed description of the invention] 1) The Minami brush, which is used many times in daily life, has a long history and is the most skillful.If you do not use it with sufficient awareness and care, it will be unpleasant, tasteless and harmful. This could lead to a serious act. The Minami brush is used for people with advanced age alveolar m1lt+, damaged or degenerated gums and teeth, but the effect is not so good that it is painful.

To compensate for this, anyone regardless of age can use it for a short period of time without paying attention or pain, and it can be used to remove extremely narrow gaps between teeth, grooves on the two sides of teeth, etc. Plaque and bacteria that have entered between the stems,
Be sure to remove food particles, etc.

2) You can also expect a massage effect on the gums with the strong pulsating jet flow from the ITli micro-porous nozzle, and a cleaning effect with the ultrasonic waves generated when air bubbles disappear.

3) By making the washer pocket-sized, you can always carry it with you anytime, anywhere, whether you are traveling or working abroad.
[This is a device that can be easily used not only in the J cavity.

Claims (1)

[Claims] 1) When the same pressure is applied to water and gas, there is a difference in the compression ratio. If the difference in compression ratio is used to eject the compressed mixed fluid from a porous nozzle, The compressed air accelerates the liquid jet and gives it pulsation, and in addition, when the mixed fluid is ejected from the nozzle, air bubbles disappear and the semi-atomized jet stream increases the cleaning effect and reduces water consumption. A device that produces the effect of 2) A pocket-sized jet washer device that has been miniaturized so that it can be stored in clothing, etc., and carried around at all times and used anywhere.
