Description

[Detailed description of the invention] Industrial application field This invention is used for oral cavity cleaning, gingival massage, etc. by pulsating the suctioned liquid using a liquid urging mechanism and ejecting the liquid from a nozzle. Applicable to sanitary equipment. Specifically, the present invention relates to a vibration-proofing structure that prevents vibrations generated by a liquid biasing mechanism from being transmitted to the outside in such an oral hygiene device.

Conventional technology Conventionally, in oral hygiene devices, a mounting base equipped with a liquid biasing mechanism was attached and fixed via a vibration isolating member inside an exterior case supported by rubber feet (see Japanese Utility Model Publication No. 59-42010). ).

Problems that the invention aims to solve However, with such conventional vibration isolation structures, it is extremely troublesome to assemble the vibration isolation member, which may fall when attaching the mount, and the rubber The problem was that the number of parts increased because the legs were required.

Therefore, the purpose of this invention is to solve such conventional problems in oral hygiene devices, simplify assembly, and reduce the number of parts.

Means for Solving the Problems Therefore, in the vibration isolation structure according to this invention, for example, as shown in the illustrated embodiment below, the motor 22 drives the pump 26 to operate the liquid urging mechanism 32, and the liquid urging mechanism 32 is activated. In an oral hygiene device that pulsates liquid sucked by a mechanism 32 and discharges the liquid from a nozzle 15, a plurality of rubber foot holes 30 are provided at the bottom of an exterior case, for example, a base cover 19.
, and insert rubber feet 31 having a vibration-proofing effect into the rubber foot holes 30, respectively, so that the rubber feet 31 support the outer case and come into contact with the outer case. Instead, the mounting base 21 to which the liquid biasing mechanism 32 is attached is housed in the exterior case, and is fixed on the rubber feet 31 with screws 33.

Function: The vibration generated by the liquid biasing mechanism 32 is absorbed by the rubber feet 31, which have a vibration-proofing effect, and is prevented from being transmitted to the outside.

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

FIG. 3 shows the overall appearance of an oral hygiene device equipped with a vibration-proof 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 front side (front side in the figure).
A power supply knob 12 and a pressure adjustment knob 13 are arranged side by side. On the other hand, on the base 11,
Place the coiled discharge tube 14 on it, and set up the handle attached to the tip of the discharge tube 14 (see FIG. 4). 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. 4 shows a schematic structure of the internal mechanism of the oral hygiene device shown in FIG. 3. 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, remove the cap 16, insert the tip of the nozzle 15 into the oral cavity, and turn 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.

By the way, in the illustrated embodiment, the exterior case is divided into two parts, as described above, to include the main body cover 20 and the base cover 19. As shown in FIGS. 1 and 2, a plurality (four in the illustrated embodiment) of rubber foot holes 30 are formed in the bottom 19a of the base cover 19. In these rubber foot holes 30..., rubber feet 31 each have a vibration-proofing effect.
Insert... Each rubber foot 31 has a circumferential groove 31a on its outer periphery, and the circumferential groove 31a is connected to each rubber foot hole 3.
It is fitted to the periphery of 0. The outer case is supported by the plurality of rubber feet 31. Such rubber feet 31...on top are respective foot portions 2.
A mounting base 21 on which a liquid biasing mechanism 32 consisting of a motor 22, a pump 26, etc. is mounted.
Place. Then, fix the mounting base 21 to the rubber feet 31 with screws 33, and place the mounting base 21 inside the outer case without contacting the outer case.
Store and hold.

By the way, when assembling the oral hygiene device,
First, turn the main body cover 20 over. Then, the suction side tube 27 is connected to the connecting portion 28, and the mounting base 21 to which the liquid biasing mechanism 32 is attached is inserted therein. After that, the base cover 19 with the rubber feet 31 attached to the rubber foot holes 30 is covered as described above. However, rubber feet 31...
Insert the screw 33... into the center hole of..., pass through it, screw it into the mounting base 21, lift the mounting base 21, suspend it in the exterior case, and securely screw it into the rubber feet 31... Fix it. Thereafter, it is turned over and the tank 17, discharge tube 14, etc. are placed on the outer case, resulting in the state shown in FIG.

Therefore, according to this invention, the mounting base 21 to which the liquid biasing mechanism 32 is attached is supported within the exterior case only by the rubber feet 31 that have a vibration-proofing effect, without touching the exterior case. Force mechanism 32
The vibrations generated can be absorbed by the rubber feet 31 and prevented from being transmitted to the outside.

Effects of the invention Therefore, according to this invention, the vibration isolating member does not easily come off during assembly, and the assembly is easy, and the number of parts is reduced by using the vibration isolating member and the rubber feet in common. Cost reduction can be achieved.
