Description

[Detailed description of the invention] This invention uses a pump to suck in water from a tank, applies water pressure, and sprays it out in a jet form from a nozzle at the end of a hose connected to the discharge port of the pump. To provide an oral irrigator for maintaining healthy teeth by removing dregs or by massaging the gums, and to provide a structure which is particularly small and whose main body can be covered with the tank when not in use, making the whole compact.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
1 is a cylindrical main body case with a secondary battery 2 and an electric motor 3.
, and a pump 4 and a charging transformer 5 for the secondary battery 2.
etc. are built-in.

The pump 4 is driven by an electric motor 3. Next, the mechanism 6 for transmitting the rotational force of the electric motor 3 to the pump 4 will be described. A driving rod 12 which vibrates by meshing with the driving gear 10 of the motor shaft 3' and engaging with the eccentric pin 11 on the driving gear 9 reciprocates the piston in the pump 4, or a diaphragm valve. In this type of pump, the diaphragm valve is appropriately connected to vibrate back and forth.

Several storage chambers 13, 1 are provided on the outer periphery of the main body case 1.
3... is provided, and in this storage chamber 13.13 there are nozzle bodies 14. made of several glass tubes that can be used interchangeably.
14 and a handle 15 to which the nozzle body 14 is attached are housed, and a hose 16 connecting the handle 15 and the pump 4 is wound up and housed.

Further, a liquid inlet 17 is provided on the upper surface of the main body case 1,
It communicates with the suction port of the pump 4.

18 is a rotating heir that adjusts the discharge pressure of the pump 4, and 1
9 is the heir of the power switch which is rotatably operated.

Reference numeral 20 denotes a cylindrical tank that is attached to the outer periphery of the main body case 1 so as to be slidable up and down, and is made liquid-tight with the main body case 1 by a backing 22 that is attached to an annular groove 21 in the upper part of the tank. .

When the tank 20 is slid upward, the tank 20
The flange 23 at the lower end engages with the rib 24 of the annular groove 21 and stops, and the tank 20 is held by the pressure force with the backing 22 so as not to fall.

In this way, water is poured into the tank 20 after the lid 25 is removed.

When the tank 20 is slid downward, it covers the entire main body case 1, and the nozzle bodies 14, 14...
, the hose 16 and the handle 15 from dust.

With the above configuration, the operation of the present invention will be described below.
When in use, slide the tank 20 upward and lift it until the lower end flange 23 comes into contact with the rib 24 above the main body case 1, as shown in FIG.

In this state, the tank 10 is held without falling due to the pressure contact force with the backing 22.

When the tank 20 is lifted in this way, various instruments,
That is, the nozzle bodies 14, 14, hose 16, handle 15, operation knobs 18, 19, etc. appear and are ready for use.

Therefore, when the user attaches the nozzle body 14 exclusively to the tip of the handle 15, then pours an appropriate amount of water into the tank 20, and turns the power switch 19, the electric motor 3 rotates, and its rotational motion is converted. The mechanism 6 converts the movement into a reciprocating motion, and the pump 4 is operated.

When the pump 4 is operated, the water in the tank 20 enters the pump 4 from the liquid inlet 17 on the top surface of the main body case 1, is applied water pressure, flows out from the discharge port to the hose 16, and enters the nozzle body 14 at the tip of the handle 15. A jet of water will be ejected from its mouth.

Therefore, by applying the tip of the nozzle body 14 to the teeth or gums, the jet-like water stream removes food particles and also stimulates the gums to make them stronger.

The force of the jet water stream to be discharged can be freely changed using the adjustment heir 18.

After use, place the nozzle bodies 14, 14..., handle 15 and hose 16 in the storage chamber 13 of the main body case 1 again.
When the tank 20 is closed as shown in Fig. 4 and then pushed down, the main body case 1 is completely covered as shown in Figs.
In addition to being protected by zero, the entire device becomes more compact than when in use, does not require a large space for storage, and is convenient for carrying.

As described above, the present invention forms a housing chamber for the hose connected to the pump and the nozzle body attached to the tip of this hose on the outer periphery of the main case housing the liquid pump, and the upper surface of the main case is provided with a liquid inlet, and is also provided with a tank that can be slid up and down on the outer periphery of the main body case, and the tank covers the main body case in the downward movement position and covers the upper surface of the main body case in the upward movement position. and a peripheral wall of the tank, so that the tank and the main body case cover can be used as one part, and the cover can be removed and turned over to be attached to the main body case. Compared to other liquid containers, we provide a highly practical oral irrigator that does not pose problems such as positioning when worn, can be easily used as a tank or a cover, and has a simple structure. can.
