Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Based on the problems in the prior art, the present embodiment provides a U-shaped toothbrush head, as shown in fig. 1, the U-shaped toothbrush head of the present embodiment comprises: brush head main part 100 and activity brush head 200, activity brush head 200 is located the afterbody of brush head main part 100, activity brush head 200 with brush head main part 100 is connected and is formed the U type toothbrush head, activity brush head 200 is used for the pressurized back activity brush head 200 is followed brush head main part 100 outwards splits the deformation.

The U-shaped toothbrush head in the prior art utilizes the elasticity of self to carry out local expansion, and the elasticity of U-shaped toothbrush head is limited, leads to restricting the scope of its both ends extension like this, and human oral cavity is not of uniform size, and U-shaped toothbrush head is also not all customized, mainly still is several main general editions on the market, like children's edition and adult's edition, consequently, general U-shaped toothbrush head is not very suitable for comparing in some users, if the phenomenon too tight or too loose of U-shaped toothbrush head and tooth cooperation appears, influences user's use experience.

The working principle of the U-shaped toothbrush head provided by the embodiment is as follows:

the movable brush head in this embodiment is located the afterbody of brushing the head main part, and the movable brush head forms U type toothbrush head with brushing the head main part and being connected, and the movable brush head is after the pressurized, and the movable brush head outwards splits open deformation along brushing the head main part, and U type toothbrush head pressurized back promptly, its both ends can produce a great deformation that splits open to the not unidimensional user's oral cavity of this adaptation.

The U-shaped toothbrush head provided by the embodiment has the beneficial effects that:

the movable brush head in this embodiment is located the afterbody of brushing the head main part, movable brush head and brush the head main part and be connected formation U type toothbrush head, movable brush head pressurized back, movable brush head is along brushing the outside deformation that splits of head main part, U type toothbrush head pressurized back in this embodiment, its both ends can produce a great deformation, user's oral cavity tooth of equidimension not of adaptation, the brush hair of can being convenient for can reach the wisdom tooth position, can not have the clean tooth in dead angle, therefore, U type toothbrush head and tooth cooperation are inseparable in this embodiment, can avoid appearing U type toothbrush head and tooth cooperation tension or tension phenomenon, U type toothbrush head can facilitate the use in this embodiment, it is effectual to brush teeth, can improve user's use experience.

Specifically, referring to fig. 1, the number of the movable brush heads 200 is two, and the two movable brush heads 200 are specifically: locate first movable brush head 201 of brush head main part 100 left side afterbody and locate the second movable brush head 202 of brush head main part 100 right side afterbody, just the second movable brush head 202 with first movable brush head 201 bilateral symmetry sets up.

Under the general condition, the tooth in human oral cavity is bilateral symmetry distribution (theoretically speaking have some slight differences, can ignore), in this embodiment, second activity brush head 202 with first activity brush head 201 bilateral symmetry sets up, embolias the tooth with U type toothbrush head on, and second activity brush head 202 and first activity brush head 201 can outwards split simultaneously and deform, can adapt not user's oral cavity tooth of equidimension, easy operation, convenient to use.

In one embodiment, in conjunction with fig. 1, a partial gap is provided between the movable head 200 and the head body 100.

In this embodiment, a local gap is formed between the movable brush head 200 and the brush head main body 100, that is, the U-shaped brush head forms the movable brush head by setting the local gap, so as to facilitate the elastic deformation of the movable brush head.

When U type toothbrush head used among the prior art is that the user contains in the mouth, U type toothbrush head adopts the plastic material preparation to form, consequently U type toothbrush head self has certain elasticity, can produce certain outside extension after U type toothbrush head pressurized, but deformation is not big, and produce easy the recovering after deformation, if certain user uses U type toothbrush head, because the oral cavity is great, embolia the tooth with general U type toothbrush head after, U type toothbrush head can deform and restore the force, can lead to U type toothbrush head and tooth cooperation tension like this, influence the effect of brushing teeth of U type toothbrush head, influence user's use and experience. Being provided with local clearance between activity brush head 200 and the brush head main part 100 in this embodiment, activity brush head pressurized back, the deformation that outwards splits along brush head main part can be fast followed to the activity brush head through local clearance, and local clearance can weaken the deformation of activity brush head and restore power moreover for U type toothbrush head can match not unidimensional tooth, convenient to use, and it is effectual to brush teeth, can improve the comfort level of brushing teeth, improves user's use and experiences.
