Description

Toothbrush

Technical field

The present invention relates to a kind of toothbrush, flow to handle or the saliva that is mixed with toothpaste that falls from here make dirty hand and clothes from bristle portion along brush holder support when it can prevent to brush teeth.

Background technology

Existing this toothbrush as shown in Figure 7, it is an electric toothbrush B, has designed the collar 22 (for example, with reference to patent documentation 1) that is used for cutting off current between the handle 21a of brush holder support 21 and the 21b of bristle portion.

According to this electric toothbrush B, when brushing teeth, blocked by the collar 22 along the saliva that is mixed with toothpaste that brush holder support 21 flows out from the 21b of bristle portion, therefore can not flow to handle 21a, like this, be used for catching the hand of handle 21a and the cuff of clothes just can not made dirty by described saliva.

Patent documentation 1, the i.e. real flat 7-30751 communique (the 2nd, 3,8 page, Fig. 1) of opening of JP.

The problem that the present invention will solve

But, as above-mentioned, because in existing electric toothbrush B, the saliva that is mixed with toothpaste is blocked by the collar 22, and only makes it can not flow to handle 21a, so the saliva that is blocked on the collar 22 still can fall make dirty clothes and floor along it.

Particularly when ward, nurse etc. brush teeth for the old man of bed and intellectually challenged or patient, the saliva that is mixed with toothpaste can be fallen on bedding such as bed clothes, nightwear and the clothes, thing is done dirty.

Can be by receptions such as recipients with the saliva that falls with saliva, thus can not make bed clothes dirty, but this can not receive well, but also pretty troublesome.

The objective of the invention is to solve so existing problem, a kind of toothbrush is provided, wherein, when brushing teeth, flow to the saliva that is mixed with toothpaste of handle along brush holder support, before arriving handle, be collected and store, and can not fall from bristle.Be used to solve the technical scheme of problem

For achieving the above object, toothbrush provided by the invention relates to following toothbrush, wherein, front end at brush holder support is a bristle portion, the latter half of brush holder support is a handle, it is characterized in that above-mentioned as the brush holder support of handle on or on the brush holder support of bristle portion side according to the ring-type storage cylinder that has circular opening with the coaxial mode setting of this bar, this tube is when brushing teeth, the saliva that is mixed with toothpaste that will flow to handle along brush holder support from bristle is from being arranged on circular opening between bar and sending into storage cylinder and storing.

Wherein B1, B2 represent toothbrush, 1,11 expression brush holder supports, and 1a represents handle, 2,12b represents bristle portion, 3,13 expression ring-type storage cylinders, 3b, 13b represent short tube, 12 expression vibration brushes, 12a represents quarter butt, m1, m2 represent endless groove.

The specific embodiment

With reference to the accompanying drawings embodiments of the invention are described.

The toothbrush B1 of embodiment 1 is as Fig. 1-shown in Figure 3, for a kind of front end at brush holder support 1 has the manual toothbrush of bristle portion 2, on above-mentioned brush holder support 1, be provided with the ring-type storage cylinder 3 with circular opening 3a coaxial with it between two ends.

The handle 1a of brush holder support 1 has identical section configuration on its total length, be ellipse.Ring-type storage cylinder 3 entangles handle 1a by its short tube 3b at the place, axle center and releasably is arranged on the brush holder support 1.The size of short tube 3b makes it can entangle handle 1a just, at the state that is placed in handle 1a, realizes water-stop between short tube 3b and the handle 1a.Ring-type storage cylinder 3 can be taken off cleaning after brushing teeth.

Circular opening 3a is used for the saliva that is mixed with toothpaste that flows on the brush holder support 1 from bristle 2 is sent into the ring-type storage cylinder 3.

Ring-type storage cylinder 3 is arranged on the handle 1a of brush holder support 1, just uses on the brush holder support of close bristle 2 one ends of handengagabie portion 1a.When grasping handle 1a, the storage cylinder 3 that is positioned at herein can not cause unnecessary obstruction, and in addition, ring-type storage cylinder 3 also can not be run into people's face when brushing teeth.

Moreover as above-mentioned, because ring-type storage cylinder 3 is provided with according to the mode that is enclosed within on the brush holder support 1, therefore, it can be slidingly arranged on the desirable position.

In ring-type storage cylinder 3, as Fig. 2 and shown in Figure 3, inner circumferential surface forms hemispheric endless groove m1, and this groove m1 just is used for storing the saliva that is mixed with toothpaste that flows into along circular opening 3a through brush holder support 1 from bristle 2.

Because the toothbrush B1 of embodiment 1 has above-mentioned such structure,, among the endless groove m1 by circular opening 3a inflow ring-type storage cylinder 3, and be trapped in herein so when brushing teeth, flow to the saliva that is mixed with toothpaste of handle 1a through brush holder support 1 from bristle 2.

When brushing teeth, toothbrush B1 rotates around it, owing to there is certain gradient, therefore the saliva of being detained can not overflowed from endless groove m1 and falls before being arrived certain amount.

The toothbrush B2 of embodiment 2 is as shown in Fig. 4-6, be a kind of electric toothbrush, wherein, at front end the vibrations brush 12 that is made its vibrations by the driving power in the bar is installed releasably, on the quarter butt 12a of above-mentioned vibrations brush 12, between two ends, be provided with ring-type storage cylinder 13 coaxial with it, that have circular opening 13a as the bar 11 of handle.

The structure that this ring-type storage cylinder 13 is arranged on the quarter butt 12a is identical with the structure that the ring-type storage cylinder 3 among the embodiment 1 is arranged on the bar 1.

Just, the section configuration of the root of quarter butt 12a is circular.Ring-type storage cylinder 13 relies on the short tube 13b of its axle center part to entangle quarter butt 12a and releasably is arranged on the bar 12a.The size of short tube 13b can be enclosed within on the bar 12a it just, at the state that is placed on the bar 12a, realizes water-stop between short tube 13b, the bar 12a.After brushing teeth, ring-type storage cylinder 13 can take off cleaning.

Label 14 expressions are arranged on the switch of the above-mentioned power supply on the bar 11.

Ring-type storage cylinder 13 is positioned at the end of the close handle 11 of above-mentioned quarter butt 12a.

Circular opening 13a is used for the saliva that is mixed with toothpaste that flows on the bar 12a from bristle 12b is sent into the ring-type storage cylinder 13.

In ring-type storage cylinder 13, as Fig. 5 and shown in Figure 6, inner circumferential surface forms hemispheric endless groove m2 similarly to Example 1, and this groove m2 is used for storing the saliva that is mixed with toothpaste that flows into through circular opening 13a along quarter butt 12a from bristle 12b.

When using the toothbrush B2 of embodiment 2 to brush teeth, the function of the ring-type storage cylinder 3 among the function of its ring-type storage cylinder 13 and the embodiment 1 is identical.

In addition, in embodiment 1,2, ring-type storage cylinder 3,13 is arranged on the bar of brush side of handle, also can same structure be arranged on the handle.

Beneficial effect
