Description

[Detailed description of the invention] This invention relates to a portable oral cavity cleaner that removes dirt by jetting water onto the teeth. The nozzle body and the grip body have three parts, the hose on the negative side is connected to the pump outlet on the oral irrigator body side, and the nozzle body and the grip body are connected to the body when the main body is used. The prop can be stored on a pair of support legs that can be expanded for stable support, simplifying the method for storing parts.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
The oral irrigator indicated by reference numeral 1 has a tank 3 with a lid 2 on the top into which water can be poured, and a main body 4 has a built-in battery, motor, liquid pump, etc. Although not shown, the liquid pump has a discharge port. It opens on one side of the main body 4.

Further, an adjustment head 5 for changing the discharge force from the pump and a power switch head 6 are provided on one side of the main body 4.

The width of the main body 4 in the transverse direction is narrower than the width of the tank 3, and the main body 4 has projecting portions 7, 7 such that one end thereof is in the middle.

The base ends 9, 9 of the support legs 8, 80 are pivotally attached to the back side of the projecting portion 7.7.

Next, to explain the structure of this point, the supporting legs 8.8 made of synthetic resin or the like are connected to each other by a connecting piece 10 in the shape of 〉. 11,1
1 is provided protrudingly.

A plate-shaped engagement piece 12 is integrally provided at the semicircular top of the connection piece 100.

On the other hand, a serrated engagement portion 13 with which the engagement piece 12 engages is formed on the bottom surface of the main body 4, and, although not shown, the lower surface of the projecting portion 1°I of the main body is provided with the support portion 13. 11.1
1 is provided with a hole into which it fits.

Therefore, the support shaft 11゜11 is inserted into this hole, and the stopper 1 is inserted into the circumferential groove 14゜14 at the tip of the support shafts 11, 11.
5 is fitted and attached, and the engaging piece 12 is attached to the fourth
, 5, the installation is completed by locking to the merging portion 13, and the support legs 8.8 can be opened and closed freely.

Incidentally, reference numeral 15 denotes a grip body having a hose 16 on its side, and a nozzle tip 18 is screwed onto the tip opening 11 of the grip body.

The distal end of the hose 16 is connected to a discharge port of a pump opened on the side surface of the main body 4, and the water sent from the pump is jet-shaped and ejected from the distal end port 17 of the nozzle tip 18.

Several nozzle tips 18t, 18...41 are prepared, and in the present invention, they are fitted into holes 19, 19... formed on the upper surface of one of the support legs 8, so that the nozzle tips 18t, 18, . It is possible.

On the other hand, the other support leg 8 has a hole 20 into which the grip body 15 is inserted.
A support piece 21 is provided to prevent the hose 16 from falling when it is bundled and placed, and has a holding function as shown in FIG.

Then, as shown in Figs. 1 and 2, the nozzle tips 18, 18, -
When the supporting legs 8,8 are closed with the grip body 15 and the grip body 15 leaning against each other, the supporting legs 8.8 are positioned along both sides of the main body 40 and do not protrude from the main body 4.

When using the above configuration, when the support legs 8, 8 are expanded in the direction of arrow a as shown in FIG.
As shown in the figure, it is locked to the front end of the engaging part 13 and held in that state so that the main body 4 can be stably supported even when water is poured into the tank 3.

Next, connect the hose end of the grip body 15 to the pump outlet opening on the side of the main body, connect the nozzle tip 18 to the grip body 15, fill the tank 3 with water, and turn on the power switch 6.
, the water in the tank 3 is sucked in by the liquid pump, sent out through the pump discharge low hose 16, the grip body 15-P nozzle tip 18, and is ejected from the tip port 17 of the nozzle tip 18 in the form of a jet.

Therefore, this jet water removes food particles between teeth,
You can clean your teeth beautifully.

When storing after use, each support leg 8 is
, 8 to support the grip body 15, its hose 16, and nozzle tips 18, 18..., and then close both legs 8, 8 in the direction indicated by the arrow. The other part is the concave part 22 when viewed from the projecting part 7°7 of the main body 4.
．． 22 along both sides 4', 4' of the main body 4.

Therefore, parts such as the grip body 15, nozzle tips 18, 18, . . . can be compactly stored in the main body side while leaning against the support legs 8, 8, and there is no need to worry about finding a place to store the parts.

As described above, the present invention is an oral irrigator that has a tank on the top and a built-in battery, motor, and liquid pump, and has a pair of support legs that allow the main body to be placed stably during use. The base end is pivotally attached to the bottom of the main body so that it can be opened and closed freely, and the grip body equipped with a hose as an accessory and a plurality of nozzle tips that are exchangeably attached to the grip body can be propped up on the support legs. It's Nishide.

Therefore, there is no need to separately consider the storage location of the accessory parts, and since the support legs can be closed along both sides of the main body with the accessory parts still attached, the overall size when not in use is significantly smaller. This has the practical effect of making it more compact.
