Description

[Detailed Description of the Invention] The present invention relates to a toothbrush device that allows you to brush every nook and cranny during the day using tap water.

Conventionally, the inside of the mouth, including the teeth, was cleaned using a toothbrush or a toothbrush, but it is extremely difficult to completely remove food residues that are stuck between the teeth and teeth with orthodontic appliances. I was worried that the residue would cause tooth decay and bad breath.

In view of the above-mentioned points, the present invention has been developed by ejecting tap water containing air bubbles from the brush part of the toothbrush, so that it is possible to clean every nook and corner during the day that cannot be reached with a toothbrush. The present invention aims to provide a toothbrush device that can be controlled as desired using an automatic on-off valve device attached to the water faucet and a manual cock attached to the brush handle. A detailed description will be given with reference to the accompanying drawings.

Also, in the middle of the water passage 31a provided in the brush body 31,
As shown in FIGS. 3 to 5, an air intake port 35 formed in a cylindrical shape is provided, and the air taken in through this intake port 35 is treated as air bubbles and is sent to the spout hole 34 together with the tap water.
・More gushes out.

Reference numeral 36 denotes a manual cock that is slidably attached to the side surface of the handle 33, and a control cylinder 38 is fixed to the cock shaft 36a that protrudes from the slide slot 37 into the water passage 33a.

In addition, a control valve body 39 formed into a substantially conical shape is attached within the tip of the passageway 33a into which the plate end 31b of the brush body 31 is fitted, with the tip facing toward the distal end of the passageway 33'a. On the back side of the control valve body 39, there are a plurality of slits 40 and 40, which allow the two-way water channels 33a and 31a to communicate with each other.
... is cut out.

Reference numeral 41 denotes a rubber cylinder installed in the water passage 33a. One end of the rubber cylinder 41 is clamped and fixed to a fixed collar 42 provided in the end of the water passage 33a, and the middle part is fixed to the control cylinder 38.
The brush body 31 is inserted into the inside, and the other end side is fitted with the brush body 31.
It is sandwiched between a fixed cylinder 43 that fixes the plate end 31b of the rubber cylinder 41 and the inner wall surface of the handle 33. Therefore, in the handle 33, the inside of the rubber cylinder 41 serves as a substantial water passage 33a.

Reference numeral 44 denotes a coil spring interposed between the end of the control cylinder body 38 and the fixed collar 42, and the control M body 38 is constantly slid to the left in FIG. 3 by the elastic force of this spring 44. The tip edge 38a presses the middle part of the rubber tube 41 against the surface of the control valve body 39 to block the water passages 33a and 31a, but the manual cock 36 can be slid and controlled as shown in FIG. When the cylinder body 38 is slid to the right against the coil spring 44, the tip edge 3 against the rubber cylinder 41
In order to separate the rubber tube 41 from the control valve body 39 when the pressure of the rubber tube 8a is released, the two-way water channels 33a and 31a are communicated through the slits 40, as shown by the arrows in the figure.

Since the present invention has the above-described configuration, in the case of the illustrated embodiment, when the faucet 2 is opened and tap water is supplied, the tap water is passed through the hose 4 from the branch port 24 of the automatic on-off valve device body 3. Water is supplied to the toothbrush body 5 side, and the manual cock 36 of the toothbrush body 5 is further operated to open water passages 33a and 31a as shown in FIG.
When the tap water is opened in a communicating state, the tap water is vigorously jetted out from the part of the brush 32 provided at the tip of the brush body 31, and can wash the inside of the mouth.

In addition, since the tap water takes in air from the air intake port 35 when flowing, a large number of fine air bubbles are formed in the tap water spouted from the brush 32, and these air bubbles generate ultrasonic waves and exert a pine surge effect. I can do it.

In the embodiment shown in FIG. 2, the switching valve 25 of the automatic opening/closing valve device body 3 is pressed onto the valve seat 27 by operating the operating shaft 28, and the tap water passes through the branch port 24 to the toothbrush body 5. However, if during this water discharge, for example, the hose 4 is stepped on or broken and the water pressure on the water discharge route side increases unreasonably, the manual cock 36 is released and the water flow channels 33a and 31a are released. When the water discharge from the brush 32 is stopped as shown in FIG. 3, the valve body 14 of the automatic on-off valve device body 3 automatically opens the valve as shown in FIG. Since the seat 15 is closed and the supply of tap water to the water discharge path side is stopped, problems such as a bursting accident of the hose 4 or water leakage from the toothbrush body 5 can be completely prevented.

When the toothbrush body 5 is not in use, as described above, the manual cock 36 is released to shut off the water passage, and the switching valve 25 of the automatic opening/closing valve device body 3 is operated with the operating shaft 28 to close the valve seat 27. If the water outlet 13 is left open, tap water can be used in the same way as normal by opening and closing the faucet 2.

As mentioned above, according to the present invention, tap water containing air bubbles is vigorously jetted from the brush part, so the jetted tap water cleans every corner of the mouth that could not be reached with a toothbrush until now, and removes cavities. In addition, the air bubbles contained in tap water exert an ultrasonic pine surge effect and improve blood circulation in the gums, so it has excellent benefits such as helping to prevent cavities in the alveoli. The tap water can be freely controlled from the toothbrush body by operating the manual faucet, so there is no need to open and close the water faucet each time it is used. By doing so, it is possible to supply tap water to the toothbrush body side very easily, or to switch it to normal use. The practical value is enormous.
