JPH02134150A - Mouth washer - Google Patents

Abstract

PURPOSE:To soften the working of washing water on the gum without lowering of mouth washing effect and massage effect by providing an air mixing portion for mixing air in washing water supplied to a nozzle. CONSTITUTION:Washing water sent from a pressure pump 6 is passed through a throttle nozzle 31 and jetted from a nozzle 32. At this time, when an adjusting port is superposed on an intake port 33, air sucked from the intake port 33 is mixed in washing water, and washing water emitted from the nozzle 32 has mixed air as a lot of bubbles. Washing water mixed with bubbles is weak in energy, but a high washing effect and softness the working, so that a user has no pain in the gum, and water is kept from scattering in the periphery. Further, while the working is soft, the bubbles collide the gum and sping off to give comfortable massage feeling to a user.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an oral cavity cleaning device that uses a jet of cleaning water sprayed from a nozzle to remove food particles that are difficult to remove with tooth brushing or the like, and to perform gum surgery.

[Conventional technology]

Oral cleaning devices that spray cleansing water from a nozzle have already been commercialized, and devices that are combined with electric tooth brushing are also available. This oral cleaning device generally consists of a water supply tank that holds cleansing water, a pressure pump that pressurizes and sends out the cleansing water supplied from the water tank, and a pressurized pump that is connected to the pressurized pump via a tube to receive the cleansing water. It consists of a nozzle that ejects water as a jet. And Utsukai Showa 55-729
No. 13 discloses a system in which the pressure of cleaning water sent out from a pressurizing pump can be adjusted by controlling the rotational speed of a motor for driving the pressurizing pump.

[Problem to be solved by the invention]

Here, the user generally adjusts the pressure based on the condition of the gums. In other words, users who feel damage to their gums due to engorgement etc. set the pressure low. In some cases, it becomes difficult to remove food particles and swell the gums. The present invention was made in view of the above points, and its purpose is to provide an oral cavity cleaner that can soften the contact of cleaning water to the gums without reducing the oral cavity cleaning effect or the pine surge effect. We are in the process of providing equipment.

[Means to solve the problem]

Therefore, the present invention is characterized in that an oral cavity cleaning device equipped with a nozzle that sprays cleaning water for oral cavity cleaning is provided with an aeration section that mixes air into the cleaning water supplied to the nozzle. . [Function] According to the present invention, the cleaning water jetted from the nozzle contains a large number of air bubbles due to the mixing of air, and these air bubbles increase the cleaning effect and at the same time reduce the amount of water that hits the gums. becomes soft. [Example] The present invention will be described in detail below based on the illustrated example. As shown in FIG. and a grip 3 placed on a stand 13 protruding from one end surface of the main body 10. A nozzle 30 for jetting cleaning water is provided on the grip 3, and the grip 3 and the main body 10 A curl hose 6 connects the two. In the figure, reference numeral 15 indicates a grip 3 provided on the upper surface of the stand 13.
This is a recessed portion into which the lower end portion of the recessed portion is fitted, and is provided with a rotation preventing projection 17 shown in FIG. 3 on its inner surface. The main body 10 is constructed by housing a power transformer 51, a motor 52, a pressure pump 7 driven by the motor 52, a printed circuit board 58, etc., in a housing divided into upper and lower parts, as shown in FIG. A knob 55 for adjusting the discharge pressure connected to the pressurizing pump 7, a power knob 56, and a light emitting element 57 for display are arranged on the front surface. There is also a non-slip pad attached to the bottom that also serves as anti-vibration. In the diagram, 5 is the power cord, 50
is a code button. The motor 52 is connected to five switches that are opened and closed by a power knob 56, and its axial direction is the front-rear direction of the main body 10, and a pinion 61 is attached to the output shaft that protrudes rearward.
A gear 63 supported by a shaft 62 disposed between the motor 52 and the pressure pump 7 meshes with the pinion 61, and an eccentric cam (not shown) provided on the gear 63 is connected to the pinion 61. (1) drives a pressurizing pump 7, which is a diaphragm pump, by a connecting rod 65. In the figure, 71 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 is equipped with a bypass passage that returns some 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 lower 2. The pressure is adjusted by changing the cross-sectional area of this 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 is equipped with a throttle nozzle 31 with an inner diameter of 1'lzz inside it, and this throttle nozzle A plurality of intake ports 33 are provided at intervals in the circumferential direction on the wall surface closer to the jet port 32 than the air intake port 31, and a cylindrical adjustment body 34 is rotatably disposed on the outer peripheral surface. It has become something like this. The adjustment body 34 here includes an adjustment port 35,
By rotating the adjustment body 34 with respect to the nozzle 30, the overlapping area of the adjustment port 35 and the intake port 33 can be adjusted. Therefore, the cleaning water sent from the pressure pump 7 passes through the throttle nozzle 31 and is then injected from the jet port 32, and at this time, the adjustment port 35 and the intake port 33 do not overlap. If the intake port 33 is closed by the regulator 34, only the cleaning water will come out from the jet port 32, but when the adjustment port 35 overlaps the intake port 33, the intake The air sucked through the port 33 is mixed into the cleaning water, and the cleaning water exiting from the spout 32 contains the mixed air in the form of a large number of bubbles. Even though the water mixed with air bubbles has a weaker water force, it not only has a high cleaning effect but also has a soft touch, so your gums won't feel any pain and there will be no water splashing around. do not have. Furthermore, although the contact is soft, the popping of the bubbles gives the user a pleasant pine surge sensation. Note that the amount of air mixed in varies depending on the overlapping area of the adjustment port 35 and the intake port 33. Here, a so-called aspirator consisting of a throttle nozzle 31 and an intake port 33 is shown for mixing air.
The pressure drop when the washing water is discharged from the washing water can cause the air that has been dissolved in the washing water to form bubbles.

【Effect of the invention】

As described above, in the present invention, the cleaning water ejected from the nozzle contains a large number of air bubbles due to air being mixed in, and these air bubbles increase the cleaning effect and at the same time are effective against gums, etc. It has a soft touch, and the bubbles that burst when it hits the gums give a refreshing sensation of pine surge in the user's mouth. It provides a cleaning effect.
