[0011]

Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a partially enlarged cross-sectional view of the intraoral cleaning device of the present invention. Oral cleaning tool 1
Comprises a shaft 2 and a cleaning member 3.

First, the shaft 2 is made of a resin material by integral molding, and a drain passage 5 is provided at the center, and a liquid supply passage 4 having a slightly smaller diameter is provided in parallel with the drain passage. At the end of the shaft 2, a liquid supply port 6 that communicates with the liquid supply path 4 and a liquid discharge port 7 that is larger than that and communicates with the liquid discharge path 5 are opened.

At this time, as shown in FIG. 2, the liquid supply port 6 and the liquid discharge port 7 are provided on the same axis L of the shaft 2 and at positions shifted in the axial direction.

Next, the cleaning member 3 is made of a porous material such as sponge, and a through hole 8 is formed in the center of the column. The cleaning member 3 is attached to the shaft 2 through the through hole 8 so as to cover the liquid supply port 6 and the liquid discharge port 7 at the tip of the shaft 2.

Then, the liquid such as water and chemicals sent to the liquid supply passage 4 by the supply / discharge action of the pump, which will be described later, is discharged from the liquid supply port 6 to the cleaning member 3, and the cleaning member 3 is sufficiently supplied with the liquid. Turn to. The cleaning member 3 cleans the inside of the oral cavity and removes the waste liquid containing the residue material in the oral cavity and the substance such as tongue coating generated by dirt and various bacteria in the oral cavity. Suction and discharge.

In this example, as shown in FIG. 2, the liquid supply port 6 and the liquid discharge port 7 are provided on the same axis L of the shaft 2, but as shown in FIG. The liquid supply port 6 may be provided on the axis L1 shifted by e in the circumferential direction. This prevents the liquid supplied from the liquid supply port 6 from being immediately sucked and discharged from the liquid discharge port 7 and allows the liquid to sufficiently flow to the cleaning member 3.

As shown in FIG. 4, in order to prevent the cleaning member 3 from coming off the shaft 2, four annular convex portions 9 are formed on the outer periphery of the shaft 2, and two of them are supplied to the liquid supply port 6.
And the drain port 7. As a result, the annular convex portion 9 blocks between the liquid supply port 6 and the liquid discharge port 7, and the cleaning member 3
After sufficiently circulating the liquid on the surface of the liquid, the liquid can be suctioned and discharged to the liquid discharge port 7.

The surface 9a on the shaft tip side of the annular convex portion 9 may be an umbrella-shaped inclined surface as shown in FIG. Thereby, even when the annular convex portion 9 is provided, the tip of the shaft 2 can be easily inserted into the through hole 8 of the cleaning member 3, and the cleaning member 3 is prevented from coming off from the shaft 2 during use. be able to.

Further, in order to further prevent the cleaning member 3 from coming off the shaft 2, the tip 9b of the surface 9a on the shaft tip side may be sharpened.

Further, as shown in FIG. 6, a plurality of outward projections 10 may be provided on the outer periphery of the annular projection 9. Thereby, the detachment of the cleaning member 3 from the shaft 2 during use can be further prevented.

As shown in FIG. 7, a rigid pipe 11 having a drainage passage 5 is covered with an elastic cap 12 forming a liquid supply passage 4 between the rigid pipe 11 and the pipe 11 to form the shaft 2. Good to do. And this elastic cap 1
2, the liquid supply port 6 is opened, and the drainage port 7 is opened through both the elastic cap 12 and the pipe 11. And
An elastic cap 12 covers the liquid supply port 6 and the liquid discharge port 7.
The cleaning member 3 is attached to the outside of the.

With this arrangement, the liquid supply path 4 and the liquid discharge path 5 are provided, and the shaft 2 having the liquid supply port 6 and the liquid discharge port 7 can be simplified in structure and easily assembled.

In this example, as shown in FIG. 7, a protrusion 13 is provided on the outer periphery of the rigid pipe 11 in the circumferential direction, and the space between the elastic pipe 12 and the elastic cap 12 is fitted in an airtight manner. Thereby, the communication between the liquid supply path 4 and the drainage path 5 passing between the pipe 11 and the elastic cap 12 can be reliably blocked.

To use the intraoral cleaning tool 1 of the present invention described above, for example, as shown in FIG. 8, the liquid supply path 4 is connected to a liquid supply tank 15 through a liquid supply pipe 14.
, And further connected to a pump 17 via an exhaust pipe 16.

On the other hand, the drainage path 5 is connected to a drainage tank 19 via a drainage pipe 18 and further connected to a pump 17 via an intake pipe 20.

Then, a switch (not shown) is turned on to operate the pump 17, and the supply tank 1 is supplied through the exhaust pipe 16.
5 and suck air from the drainage tank 19.

Thus, the liquid in the liquid supply tank 15 is supplied to the liquid supply passage 4 of the intraoral cleaning tool 1 through the liquid supply pipe 14. Then, as described above, the inside of the oral cavity is cleaned by the cleaning member 3.

By operating the pump 17, the pressure in the drainage tank 19 is reduced to a negative pressure, and the drainage in the intraoral cleaning tool 1 is sucked through the drainage pipe 18.

[0029]

Therefore, according to the present invention, since the porous cleaning member is attached to the tip of the shaft, the porous cleaning member is scraped off by the surface of the cleaning member, and tongue moss formed on the mucous membrane due to dirt and various bacteria in the oral cavity. Such substances can be more reliably removed.

According to the second aspect of the invention, the liquid supply port and the liquid discharge port are separated from each other in the axial direction and the circumferential direction of the shaft. Can be prevented from being immediately sucked and discharged from the drain port, and the liquid can sufficiently flow around the cleaning member.

According to the third aspect of the present invention, the liquid supply port and the liquid discharge port are shifted in the axial direction of the shaft, and between the liquid supply port and the liquid discharge port and on the outer periphery of the shaft. Since the annular convex portion is formed, in addition to the above-described effects, the liquid supplied from the liquid supply port is prevented from being immediately sucked and discharged from the drain port by blocking with the annular convex portion, and the surface of the cleaning member is sufficiently covered with the liquid. And then drain to the drain port.

According to the fourth aspect of the present invention, the surface of the annular convex portion on the shaft tip side is formed as an umbrella-shaped inclined surface.
In addition to the above effects, the cleaning member can be easily inserted from the tip of the shaft. Further, it is possible to prevent the cleaning member from coming off the shaft during use.

According to the fifth aspect of the present invention, since a plurality of outward projections are provided on the outer periphery of the annular convex portion, in addition to the above effects, the cleaning member can be further prevented from coming off the shaft during use. can do.

According to the sixth aspect of the present invention, the shaft is formed by covering the rigid pipe with the elastic cap.
By providing a liquid supply path and a liquid discharge path, a shaft having a liquid supply port and a liquid discharge port can be simply assembled and easily assembled.
