Abstract

The invention provides a toothbrush equipped with elastic device, and it is characterized in that: bristle is planted in elastic sliding block, and bristle on tooth surface will be pressed down under drag force, and bristle among tooth slit extends to recession place. The bristle can contact with tooth surface and recession place at maximum limit all the time because of the action of elastic device, so the thorough cleaning is realized. The invention prevents incomplete cleaning because of smaller force and deformation of bristle and abrasion of tooth because of larger force.

Description

A kind of toothbrush

Technical field the present invention relates to a kind of toothbrush that has elastic device.

The toothbrush that background technology is traditional is made up of brush holder support, bristle.Under the effect of hand, toothbrush moves back and forth at dental surface during use, with cleaning teeth.Through practice test, there are some problems when using the traditional toothbrush cleaning teeth: 1, because the depression of dental surface and tooth junction can not become the plane, and no matter the bristle end face forms plane or cambered surface, all can occur in the use, firmly hour, the bristle that is in tooth connection recess is risen by frame, does not reach the purpose of thorough cleaning; And exert oneself when big, bristle contacts and is in the recess that tooth connects, and is crooked but the bristle that is in dental surface will be crushed out of shape.Compressing bristle repeatedly very easily is out of shape and makes toothbrush discarded, even if the higher bristle of quality also strikes the beam unavoidably, is problem service time.2, the bristle of oppressed distortion and dental surface contact-making surface become big, and frictional force increases, and if things go on like this, dental surface will sustain damage.Some enterprises produce the saw-toothed toothbrush of bristle, and this design is because bristle is different in size, and long brush hairs is easy deformation more.

Summary of the invention task of the present invention is: provide a kind of bristle may be with automatically flexible toothbrush, it be yielding to solve the bristle that prior art exists, the technical problem of easy damaged dental surface.

In order to reach the purpose that solves the problems of the technologies described above, technical scheme of the present invention is: the opposite end of brush holder support handle, be provided with in a row and relatively independent step trough, plant bristle and the sliding shoe similar to the step trough shape, be placed on respectively in the relatively independent groove, each sliding shoe has flexible member.When certain row brush hair meets obstructions, flexible member is compressed, and bristle is shunk back, and is lower than the bristle that is not subjected to resistance, and resistance disappears, and under the effect of flexible member, bristle sets back.Toothbrush moves back and forth, under the effect of elastic force, bristle can be connected the depth of recess according to dental surface with tooth, shrink or stretch out, and the bristle that promptly is in dental surface is shunk back by pressure, and the bristle that is in tooth connection recess maintains the original state, bristle contacts the face of being touched completely, reaches the purpose of thorough cleaning, and has reduced the chance of bristle distortion, reduced simultaneously the distortion bristle to greatest extent to strengthening friction, the damage that dental surface is caused.

Description of drawings elaborates to the present invention below in conjunction with accompanying drawing and specific embodiments.

Fig. 1 is a front view of the present invention;

Fig. 2 is a side view of the present invention;

Fig. 3 is the front view of cover plate;

Fig. 4 is the cutaway view of cover plate.

Part of the present invention: 1, brush holder support; 2, cover plate; 3, flexible member; 4, sliding shoe; 5 bristles.

With reference to Fig. 1,5 in a row the planting on sliding shoe 4 of Fig. 2 toothbrush bristle, be positioned over respectively in the step trough of brush holder support 1 other end, cover plate 2 is provided with and the friction tight projection of this groove with contacted of step trough, guarantees after combining that cover plate 2 is not open under the elastic force effect.Be uniform-distribution with aperture with reference to Fig. 3, Fig. 4 cover plate 2, be convenient to clean.The place, space of the projection of cover plate 2 and slide block 4 is provided with flexible member 3, guarantees bristle 5 when oppressed, and flexible member 3 is compressed, and sliding shoe 4 is shunk back with bristle 5, and after pressure disappeared, under the effect of flexible member 3, sliding shoe 4 and bristle 5 were got back to original position again.Under the effect of elastic device, bristle 5 can be according to the situation that is run into, and stretches out automatically or shrink back.Promptly in the process of brushing teeth, under the effect of elastic device, the bristle 5 that is in dental surface is shunk back, stretch out and be in the bristle that tooth connects recess, along with the motion of toothbrush, bristle 5 is according to the situation that is run into, and stretches out automatically or shrink back.

This structure has been guaranteed bristle and has been touched combining closely of face, bristle 5 frames or compressive deformation phenomenon when having solved traditional toothbrush and contact with tooth, and the cleaning of teeth of being more convenient for, the while has reduced the wearing and tearing of being out of shape 5 pairs of teeth of bristle to greatest extent.

Flexible member can be that spring also can be the stronger silica gel of elasticity.

Claims
