Abstract

The utility model relates to a toothbrush divided into two halves (1) hinged together along the axial direction. The toothbrush can be used as a common toothbrush at a first position and can be switched to a second position, and brush bristles (4) on a brush head (3) are extended opposite to each other.

Description

Toothbrush

The present invention relates to a kind of toothbrush with a pair of head toothbrushes that can be simultaneously the two sides of tooth be cleaned.

Prior art have two fixedly the toothbrush of head toothbrushes be two fixedly head toothbrushes toward each other, bristle is from the bristle of a head toothbrushes towards another head toothbrushes.This toothbrush has following two shortcomings: the firstth, and the gap between the bristle of two head toothbrushes is fixed, so can not the tooth of different-thickness be cleaned uniformly; The secondth, this pair of head toothbrushes makes brush head much more too fat to move than general toothbrush, therefore is difficult to only side of tooth is cleaned.

It is characterized in that comprising two and half ones according to toothbrush of the present invention, each half one comprises a long handle, and long handle one end has a head toothbrushes that bristle is housed.One longitudinal fluting extends along the inner surface of each half one, and two and half ones are around hinged with an axis of decreased food almost parallel extension; So two and half ones can pivot between a primary importance and a second place, abut against side by side together at primary importance two head toothbrushes, bristle is all roughly towards extending in the same way; Be separated from each other at the second place two head toothbrushes, the bristle of each head toothbrushes is with the bristle of an angle towards another head toothbrushes, and two handles form two sides that tilt.

By this configuration, this toothbrush can be used as an ordinary toothbrush in primary importance and uses, and then can be used to the two sides of tooth are cleaned simultaneously in the second place.

Described two and half ones are preferably adopted a film hinge hinged in addition.

By a sheath that removably is enclosed within handle outside, two and half ones of toothbrush can be remained on the primary importance and the second place.The end away from head toothbrushes that is preferably each half one is equiped with a corresponding plug, so that the interval between plug is identical with the second place in primary importance; Like this, by a retainer with two sockets that cooperate with plug, toothbrush can be remained on a position in the primary importance and the second place.This has just been avoided toothbrush in use to forward the another location to from a position by accident.

Below in conjunction with the example of description of drawings, wherein according to the toothbrush of the present invention's structure:

Fig. 1 is the vertical view of toothbrush in primary importance;

Figure 1A is the end-view of toothbrush in primary importance;

Fig. 2 is the side view of toothbrush in primary importance;

Fig. 3 and Fig. 3 A are respectively the top and bottom perspective views of toothbrush in the second place;

Fig. 3 B (making progress) and Fig. 3 C (top is downward) are the end-view of toothbrush in the second place;

Fig. 3 D (making progress) and Fig. 3 E (top is downward) are the front view of toothbrush in the second place;

Fig. 4 is the 3 dimensional drawing of toothbrush in the second place.

Accompanying drawings is according to another example of the toothbrush that passes through sheath maintenance of the present invention's structure, wherein simultaneously:

Fig. 5 is for unloading under the situation toothbrush and retainer at the vertical view of primary importance at retainer;

Fig. 5 A is the end-view of toothbrush in primary importance;

Fig. 5 B has the cross-sectional view of the retainer in the hole that can cooperate with toothbrush in the primary importance and the second place;

Fig. 6 is for shedding under the situation toothbrush and sheath at the side view of primary importance at retainer;

Fig. 7 and Fig. 7 A are respectively the top and bottom perspective views of toothbrush in the second place;

Fig. 7 B and Fig. 7 C are the end-view of toothbrush in the second place;

Fig. 7 D and Fig. 7 E are the front view of toothbrush in the second place;

Fig. 7 F has the cross-sectional view of the retainer in the hole that can cooperate with toothbrush in the primary importance and the second place;

Fig. 8 is the 3 dimensional drawing of toothbrush in the second place;

Fig. 9 and Fig. 9 A represent the operating position of toothbrush in primary importance;

Figure 10,10A, 10B and 10C represent the operating position of toothbrush in the second place.

Toothbrush shown in Fig. 1 to 8 comprises half one 1 of two symmetries, and each half one has the one handle 2 that at one end has a head toothbrushes 3.Bristle 4 vertically extends from this head toothbrushes.

Two and half ones 1 are installed in the groove along the film hinge 5 of the length direction of handle by one and are connected, as shown in figs. 1 and 6.

In primary importance, two and half ones 1 are placed side by side, and the bristle 4 of two and half ones is parallel.Shown in Fig. 9 and 9A, toothbrush can be used as an ordinary toothbrush in this position.

As hope two surfaces of tooth are cleaned simultaneously, then can easily be forwarded toothbrush to the second place.Two and half ones 1 of toothbrush forward position shown in Fig. 3 and 3A to around the hinged joint of recess.Two head toothbrushes 3 toward each other, bristle 4 then stretches into two spaces between the head toothbrushes, and forms an angle between the bristle of two head toothbrushes.It can be used to brush teeth in the mode shown in Figure 10,10A, 10B and the 10C.Two handles form two inclined sides that are easy to grip.

In another example, the end of each half one 1 all is equiped with a plug 6.The location of plug 6 guarantees that the distance between the plug is identical in the primary importance and the second place.

One retainer 7 is equiped with two and cooperates with plug and can be enclosed within socket on the plug in primary importance and the second place.Retainer 7 added be press fit on the plug 6, toothbrush is remained on the position.It must unload before forwarding toothbrush to another location, remains on second position so that toothbrush converted to.
