Next, a tooth cleaning device using a fine bubble according to an embodiment of the present invention will be described with reference to the drawings.

The tooth cleaning device 10 includes a water pipe 16 which is formed in a rod shape or a cylinder shape and is gripped by a user and has a water pipe 23 provided inside, and a head portion 17 integrally extending from the water pipe 16. , Is equipped.

In FIG. 1, in the tooth cleaning device 10, cleaning water is supplied via a water supply pump (not shown) connected to a water supply source such as a water pipe or a storage tank, and water is supplied in the same manner as a well-known shower head or the like. The wash water is supplied via a hose (not shown). Therefore, the illustration and description of the configurations of the water supply pump and the water supply hose are omitted here.

In FIG. 1, the tooth cleaning device 10 has, for example, a structure in which substantially half of the front and back separate members are combined, and includes a base member 21 on the back surface side (back surface side) and a cover member 22 on the front surface surface (front surface side). It has a headrace 23 for guiding the wash water supplied from the water supply source.

In the headrace 23, a narrow waterway 23a having a narrower pipe (hereinafter, also referred to as “flow path cross-sectional area”) than the upstream side is formed near the downstream end thereof. Therefore, in the headrace 23, the cross-sectional area of the flow path gradually decreases toward the downstream by the narrow waterway 23a.

At the downstream end of the headrace 23, the storage becomes the maximum flow path cross-sectional area after gradually increasing from the minimum flow path cross-sectional area of the narrow waterway 23a to the original flow path cross-sectional area of the headrace 23. The space portion 23b is formed.

The head portion 17 has a flat three-dimensional shape, and the tip portion thereof is integrally provided with a bent portion 17a that is bent toward the surface side. The head portion 17 is formed with a diversion channel 23c that communicates with the storage space portion 23b of the head section 23.

In the head portion 17, the wall thickness of the cover member 22 is thicker than that of the base member 21, and as shown in FIG. 1C, the middle portion of the diversion channel 23c is from the upstream side to the downstream side (tip side). ), A total of 8 locations, 4 locations and 2 locations each in the left-right width direction, are branched by the branch road 23d.

The head portion 17 is formed with a recess 22a that opens to the surface (external exposed surface) side of the cover member 22 so as to correspond to the branch path 23d. A mist ejection port 22b communicating with the branch path 23d is formed on the bottom surface of the recess 22a.

The inside of the branch path 23d has a substantially columnar shape, and a spiral groove (not shown, hereinafter also referred to as a “spiral groove”) is formed on the surface, and the water introduced into the branch path 23d is misted. A guide cylinder 25 as a plurality of mist-forming mechanisms for forming and ejecting mist W from the mist ejection port 22b is embedded. Since the spiral groove is formed in a female screw shape at a predetermined depth and angle, the water is misted while allowing the passage of water between the spiral groove and the inner wall surface of the branch path 23d.

As shown in FIG. 2, the tooth cleaning device 10 is used by inserting the head portion 17 into the mouth M of the person to be treated, and cleans the teeth T growing from the gum G of the mouth M. Then, as described above, the grip portion 15 which is formed in a rod shape or a cylinder shape and is gripped by the operator, the headrace 23 which is provided inside the grip portion 15 and guides the water supplied from the water supply source, and the grip portion. The head portion 17 provided at the tip of the head portion 15, the guide cylinder 25 provided inside the head portion 17 as a mist-forming mechanism for mist-forming the water guided by the head portion 23, and the outside of the head portion 17. It is provided on one surface (hereinafter, also simply referred to as “surface”) side of the exposed surface, and has a plurality of mist outlets 22b for ejecting the mist W generated by the guide cylinder 25.

At this time, since the bent portion 17a bent at about 40 ° to 50 °, preferably about 45 ° is integrally formed at the tip portion of the head portion 17, the back side of the tooth T can be easily cleaned. Can be done.

Next, the action and effect of mistizing the cleaning water by the tooth cleaning device 10 will be described.

As described above, since the channel cross-sectional area of the narrow channel 23a is smaller than the channel cross-sectional area of the headrace 23, the flow velocity of water increases and the pressure decreases when passing through the narrow channel 23a. As a result, cavitation occurs, and fine bubbles (finally fine bubbles that can be contained in the mist particles described later) are generated in the water.

Then, the water that has passed through the narrow water channel 23a flows into the storage space portion 23b. The water that has flowed into the storage space 23b is discharged to the diversion channel 23c. Since the flow path area of the diversion channel 23c is smaller than the flow path area of the storage space portion 23b, the flow velocity of water increases and the pressure decreases even when passing through the diversion channel 23c. As a result, cavitation occurs and fine bubbles are generated in the water.

Since the guide cylinder 25 is housed inside the branch passage 23d, the water flowing into the branch passage 23d is swirled by the spiral groove of the guide cylinder 25, the flow velocity of the water becomes faster, and the pressure decreases. As a result, cavitation occurs and fine bubbles are generated in the water.

As described above, in the tooth cleaning device 10, when the mist W is ejected from the mist ejection port 22b, water is discharged in the process in the spiral groove of the three fine bubble generating portions (narrow channel 23a, diversion channel 23c, guide cylinder 25). ) Can be included in the particles of the mist W.

As a result, the user's teeth are efficiently washed by the synergistic pressure of the ejection pressure of the mist-like mist W and the pressure at which the particles constituting the mist W pop.

It's clear that you can. Therefore, the techniques after these changes, modifications, combinations, etc. naturally belong to the scope of the technical idea of the present invention.

Specifically, in the above-described embodiment, the one in which the tip of the head portion 17 is formed in a semicircular shape is disclosed, but the present invention is not limited to this, and the shape and the like are arbitrary.

As shown in FIGS. 1B and 1C, when the tip of the head portion 17 is formed in a semicircular shape, a sharp corner portion is formed when the head portion 17 is inserted into the mouth M. Since it does not exist, it is possible to suppress catching and the like, and it is possible to prevent injury or damage to the mouth M.

Further, since the bent portion 17a bent toward the surface side is formed at the tip of the head portion 17 and the mist ejection port 22b is also provided in the bent portion 17a, the mist W is applied to the back side of the tooth T. Can be done.

Further, as shown in FIGS. 3A and 3B, when the head portion 57 is formed in a spherical shape, the mist W can be diffused to the maximum extent. At this time, the diameter of the sphere is about 1 cm, and the mist spouts (not shown) inject mist from about 3 to 6 places in total.
