[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to cleaning of interdental plaque, and a cleaning device for an oral cavity having a gingival masurge effect.

[0002]

[Technical background of the invention] According to a survey by the Ministry of Health and Welfare (1987), 80% of Japanese aged 35 and over have some gingival findings, and 80% of those aged 40 and over have a periodontal reason to lose teeth. It is a disease. Plaque adheres to the tooth surface, and endotoxins, enzymes, and bacterial products from it stimulate the gums and cause inflammation (gingivitis). Periodontitis (so-called alveolar pyorrhea) occurs when gingival tissue is further destroyed and inflammation reaches the bones supporting the teeth. The cause of periodontal disease originates in plaque, but it is difficult to remove plaque, especially in the interdental region, by a normal brushing operation. For this reason, it has been recently concluded that the reason for the high rate of periodontal disease, despite the fact that there are no Japanese who do not brush their teeth, is "particularly poor plaque removal in the interdental region".

[0003]

2. Description of the Related Art Based on the above-mentioned technical background, a number of plaque removing articles such as electric toothbrushes, mouth washer, dental floss, and interdental brushes have been developed in recent years due to an increase in awareness of oral care. I have. (A) The electric toothbrush is more expensive, as it is difficult to remove plaque in the interdental region as well as a general toothbrush, and it is relatively fast to move, so that the gums are relatively easily damaged. (B) Since the mouth washer is used by connecting it to the water tap in the washroom or is jet-washed by an electro-arterial pump, it can be used only in the washroom only. I can't get it. In addition, since the discharged washing water constantly spills out of the mouth, it is disadvantageous in that it is not overwhelmed during operation, is limited to use in a washroom, and is expensive. (C) Dental floss is not only troublesome for back teeth care, but also cannot be used for bridge teeth. In addition, there are disadvantages such as easy breakage of crowns and fillings. (D) The operation is troublesome for the interdental brush. In addition, brushes of various sizes and shapes are required, and there is an economical problem that they are easy to bend and hard to last.

An object of the present invention is to provide a cleaning device which has a simple structure, in which bubbles are alternately mixed into a fluid jet to generate pulsation, thereby improving cleaning efficiency, and at the same time being portable and low in cost. It is in.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is to provide an internal gas pressurizing device in a sealed container capable of replenishing a liquid, and pressurize the closed container without being blocked by a liquid surface. This is achieved by providing a liquid suction pipe having an air suction port, and connecting a discharge pipe provided with an injection opening / closing valve to a discharge end of the liquid suction pipe.

[0006]

[Effect] The momentum is mass × velocity, and the temporal change of the momentum is the cleaning pulse power. The mass difference between the liquid and the gas bubbles is about 1000 times, which provides a very effective cleaning action. By including air bubbles, the amount of the discharged liquid and, consequently, the amount of drainage can be reduced. When applied to a fixed-rate discharge pump mechanism, injection can be aimed at the required location when needed, so there is no fuss during use. In addition, portability is improved. Furthermore, by pre-pressurizing the air in the container, cleaning of the teeth and the like can be performed only by manually opening and closing the injection valve.

[0007]

Next, the details of the embodiment of the present invention will be described with reference to the drawings.

Reference numeral 13 shown in FIG. 1 denotes a closed container, and a liquid supply port 15 having a closed lid 14 is provided on one upper side of the closed container 13. An electric or manual pressurizing device 16 is provided at the upper part of the closed container 13 so that pressurized air is supplied to the upper part of the closed container 13. Reference numeral 17 denotes a “-shaped liquid suction pipe provided on one side inside the closed container 13, and the lower end of the vertical portion of the liquid suction pipe 17 is opened near the bottom, and the upper end is the upper side wall of the closed container 13. A base of a flexible pipe 18 is connected to the upper open end, and a discharge pipe 20 having an injection opening / closing valve 19 as a base is connected to the other end of the flexible pipe 18. 2, a suction port 21 for pressurized air is formed above the liquid suction pipe 17, that is, above the liquid level.

[0009]

[Explanation of Operation] The sealing lid 14 is detached, water is contained in the sealed container 13 to a level below the suction port 21 of the pressurized air, and after the sealing lid 14 is closed, the pressurizing device 16 is electrically driven or It operates manually and supplies pressurized air into the closed container 13. During interdental cleaning, pressurized air / liquid flows toward the discharge pipe 20 by directing the tip of the discharge pipe 20 between the teeth and opening and closing the injection on-off valve 19, during which the kinematic viscosity coefficient of gas and liquid is increased. The bubbles are automatically dispersed in the discharge pipe 20 due to the difference between the two and the effect of the surface tension, and a liquid pulse flow having a cleaning effect is generated in the nozzle portion 20a to clean the space between the teeth.

[0010]

[Effects of the Invention] As described above, according to the configuration of the present invention, the following effects can be obtained.

[0011] The cleaning effect between teeth and the like is efficiently performed by the gas-liquid pulse flow effect, and a moderate massage effect can be obtained by acting on gums and the like, and health maintenance of gums and the like can be achieved.

By including bubbles, the amount of the discharged liquid can be reduced.

[0013] By accumulating the pressure in the closed container, the cleaning operation of the teeth and the like by the continuous gas-liquid pulse flow effect can be efficiently performed by simply opening and closing the injection on-off valve.
