Embodiments Hereinafter, embodiments of this invention will be described in detail with reference to the drawings.

FIG. 4 shows the overall appearance of an oral hygiene device equipped with a nozzle storage structure according to this invention. In the figure, reference numeral 10 is the main body of the device, which is assembled onto a base 11. The base 11 has a power knob 12 and a pressure adjustment knob 1 on the front side (the front side in the figure).
Prepare 3 and 3 side by side. On the other hand, a coiled discharge tube 14 is placed on the base 11, and a handle attached to the tip of the discharge tube 14 is erected (see FIG. 5). Then, the base end of the discharge tube 14 is connected to the adjacent device main body 10. Further, a nozzle 15 is attached to the tip of the handle so as to be replaceable, and a cap 16 is covered. On the other hand, a tank 17 is placed on the device main body 10. The tank 17 has a top opening covered with a lid 18.

Now, FIG. 5 shows a schematic structure of the internal mechanism of the oral hygiene device shown in FIG. 4. Reference numeral 20 in the figure is a main body cover of the device main body 10, which together with the base cover 19 of the base 11 constitutes an exterior case of the oral hygiene device. Inside the main body cover 20 is a mounting base 21.
to store. A motor 22 is mounted on the mounting base 21. A motor gear 23 is attached to the rotating shaft of the motor 22, and meshes with a crank gear 24 supported by the mounting base 21. A crank 25 is attached to the crank gear 24, and a piston is connected to the tip of the crank 25, although not shown. The piston reciprocates within the cylinder. The cylinder is formed within a pump 26 which is supported by a mount 21. One end of a suction side tube 27 is attached to the suction port of the pump 26. Suction side tube 27
The other end is the connection part 2 between the device body 10 and the tank 17.
Attach to 8.

Therefore, when the power knob 12 is turned on, the motor 22 is driven and its rotation is transmitted to the crank gear 24 via the motor gear 23. The rotation of the crank gear 24 rotates the base end of a crank 25 eccentrically attached thereto, causing a piston connected to the tip to reciprocate. As a result, the liquid in the tank 17 is sucked into the pump 26 from the connection part 28 through the suction side tube 27, and the sucked liquid is energized by the pump 26 and sent out to the outside of the apparatus main body 10. Then, the liquid is discharged in a pulsating manner from the nozzle 15 attached to the handle 29 through the discharge tube 14. Therefore, insert the tip of the nozzle 15 into the oral cavity through the cap 16, and press the pressure adjustment knob 1.
3 while adjusting it appropriately, the pulsating flow discharged from the nozzle 15 can clean the inside of the oral cavity and perform gingival massage.

Therefore, when using this type of oral hygiene device, each person puts the tip of the nozzle 15 into their own oral cavity, so each person who uses it has to prepare one nozzle 15 for his or her own use. This is sanitary, and usually a plurality of nozzles 15 are prepared. For this reason, it is necessary to store all the nozzles 15 when the device is not in use, and to store the nozzles 15 that are not in use somewhere when the device is in use. Therefore, in the illustrated embodiment, a nozzle storage chamber 30 is formed within the apparatus main body 10 as shown in FIGS. 1 and 2.

The nozzle storage chamber 30 is formed within the apparatus main body 10 by being partitioned by the vertical wall 20a of the main body cover 20, as shown in the figure. Then, a loading/unloading port 30a is opened on the tank mounting surface 10a of the apparatus main body 10 on which the tank 17 is mounted, an upward step 30b is provided in the middle, and the lower part 30c is opened.

On the other hand, in the illustrated embodiment, a liquid receiving part 19b is formed at a position of the base cover 19 of the base 11 corresponding to the lower part of the nozzle storage chamber 30, surrounded by a protrusion frame 19a, and a liquid escape hole 19c is formed in the liquid receiving part 19b. Open. The liquid that has fallen from the nozzle storage chamber 30 is received by the liquid receiving part 19b, and the liquid that has fallen there is released from the liquid escape hole 19c so as not to stagnate.

A mounting portion 15a is provided to the mounting portion 15a.
A flange portion 15b is formed adjacent to the flange portion 15b. A liquid hole 15c passes through the center, and a nozzle portion 15d is formed at the tip with the liquid hole 15c having a small diameter.

However, when storing the nozzle 15 after use,
Remove the tank 17 from the top of the device main body 10, and insert the nozzle 15 into the nozzle storage chamber 30 through the inlet/outlet 30a of the tank mounting surface 10a with the mounting part 15a facing upward.
Insert inside. Then, as shown in FIGS. 1 and 2, the flange 15b is hung on the intermediate step 30b, and the nozzle is hung into the nozzle storage chamber 30 for storage. On the other hand, when taking out the nozzle 15, the tank 17 is similarly removed from the apparatus main body 10, and the nozzle 15 stored in the nozzle storage chamber 30 is pulled up by holding the mounting part 15a through the inlet/outlet 30a of the tank mounting surface 10a. After taking out the nozzle 15, the tank 17 is placed on the apparatus main body 10 again. Then, the tank mounting surface 10a is hidden by the tank 17, and the nozzle storage chamber 30 is no longer visible from the outside.

According to the illustrated embodiment, the liquid spilled from the nozzle 15 stored in the nozzle storage chamber 30 is received by the liquid receiving part 19b, and the liquid is immediately discharged to the outside through the liquid escape hole 19c.
