Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

The present invention uses a jet of cleaning water jetted from a nozzle,
The present invention relates to an oral washing device that removes food debris that is difficult to remove with a toothpaste and performs gum massage.

[Prior art]

Mouthwashing apparatuses for spraying washing water from nozzles have already been commercialized, and ones combined with electric toothpaste have been provided. This mouth washing device is generally connected to a water supply tank for storing the wash water, a pressurizing pump for pressurizing and supplying the wash water supplied from the water supply tank, and a pressurized pump via a tube, and the received cleansing water is supplied thereto. And a nozzle for jetting water as a jet. And 55-72913
In Japanese Patent Application Laid-Open Publication No. H11-157, there is disclosed an apparatus in which the pressure of the cleaning water sent from the pressurizing pump can be adjusted by controlling the number of rotations of a motor for driving the pressurizing pump.

[Problems to be solved by the invention]

Here, the user generally adjusts the pressure in the state of the gums. In other words, if the user feels damage to the gums due to alveolar wax, etc., the pressure is set low.However, if the pressure is reduced in this way, there will be no residue on removal of food debris and massage of the gums. Will be. The present invention has been made in view of such a point, and an object of the present invention is to provide a mouthwash that can soften the washing water on the gums without reducing the mouthwash effect and the massage effect. In providing the device.

[Means for Solving the Problems]

Thus, the present invention provides an oral cavity washing device provided with a nozzle for injecting washing water for oral cavity washing, in which an air mixing section for mixing air into the cleaning water supplied to the nozzle is provided, and the air mixing section includes It is characterized by using a material capable of continuously changing the opening area of the mouth. [Operation] According to the present invention, the cleaning water ejected from the nozzle contains a large number of air bubbles due to the incorporation of air.
Because the contact with the gums etc. is soft and the amount of air mixed can be changed continuously,
The specific softness can be set as desired. [Embodiment] Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. As shown in FIG. 2, this mouth washing device 1 has a horizontally long rectangular parallelepiped main body 10 in which a water supply tank 4 is disposed on an upper surface. And a grip 3 placed on a stand 13 protruding from one end surface of the main body 10, and a nozzle for jetting washing water.
30 is provided on the grip 3, and the grip 3 and the main body 10 are provided.
Are connected by a curl hose 6. In the figure
Reference numeral 15 denotes a recess provided on the upper surface of the stand 13 and into which the lower end of the grip 3 is fitted.
17 is provided on the inside. As shown in FIG. 3, the main body 10 includes a power transformer 51, a motor 52,
The pressure pump 7 driven by the pressure pump 7, a printed circuit board 58, etc. are housed, and a knob 55 for discharge pressure adjustment connected to the pressure pump 7 on the front surface, a power supply knob 56, And a light emitting element 57 for display. In addition, a non-slip 19 which is also used for vibration isolation is attached to the bottom surface. In the figure, 5 is a power cord, and 50 is a cord bush. The motor 52 connected to the switch 59 opened and closed by the power supply knob 56 has its axial direction set to the front-rear direction of the main body 10, and a pinion 61 attached to an output shaft protruding rearward. A gear 63 supported by a shaft 62 disposed between the pinion 61 and the pressurizing pump 7.
An eccentric cam (not shown) provided on the gear 63 drives the pressure pump 7 which is a diaphragm pump by a connecting rod 65. In the figure71
Is a suction port connected to the water supply tank 4, and 72 is a discharge port to which the other end of the curl hose 6 is connected. The pressurizing pump 7 has a bypass passage that returns a part of the water to the suction side when the volume of the pressure chamber is reduced by driving the diaphragm and the cleaning water in the pressure chamber is sent to the discharge port 72. The pressure is adjusted by changing the cross-sectional area of the bypass passage. As shown in FIG. 1, the nozzle 30 attached to the grip 3 connected to the pressurizing pump 7 through the curl hose 6 has a throttle nozzle 31 having an inner diameter of about 1 mm therein. A plurality of intake ports 33 are provided on the wall surface on the side of the jet outlet 32 at intervals in the circumferential direction, and a cylindrical adjusting body 34 is further rotatably arranged on the outer peripheral surface. It has become something. The adjusting body 34 here has an adjusting port 35, and by rotating the adjusting body 34 with respect to the nozzle 30, the overlapping area between the adjusting port 35 and the suction port 33 can be adjusted. I have. Thus, the washing water sent from the pressure pump 7 is
After passing through the throttle nozzle 31, it is ejected from the ejection port 32, and at this time, the adjustment port 35 and the intake port 33 do not overlap, and the intake port 33 is closed by the adjustment body 34. If it is, only the washing water exits from the jet port 32, but when the adjustment port 35 overlaps the intake port 33, the air sucked from the intake port 33 is mixed into the washing water. In addition, the washing water flowing out from the ejection port 32 has mixed air as a large number of bubbles. And although the washing water mixed with air bubbles has a weak water force, the washing effect is high and the hit is soft, so the gums do not feel painful and there is no water splashing around . Furthermore, although the hit is soft,
The bursting of the bubbles gives the user a pleasant massage feeling. Note that the amount of air to be mixed varies depending on the overlapping area between the adjustment port 35 and the intake port 33.

【The invention's effect】

As described above, in the present invention, the cleaning water ejected from the nozzle contains a large number of air bubbles due to the incorporation of air, and the air bubbles increase the cleaning effect, and at the same time, increase the cleaning water The contact is soft, and the air bubbles that pop on the gums etc. give a refreshing massage feeling to the user's oral cavity. The cleaning effect can be obtained, and furthermore, by continuously changing the opening area of the intake port, the amount of air to be mixed can be adjusted to a desired state by each person, and accordingly, each user is comfortable. The state can always be obtained.
