Description

Front push type replacement brush head toothbrush

This creation relates to a toothbrush, and more particularly to a toothbrush that pushes the brush head forward.

At present, most of the commercially available toothbrushes are made of plastic materials, and their service life is usually about three months. When the bristles on the toothbrush are in contact with the teeth, the wear will be a certain degree of wear, and the cleaning performance is reduced and easy. It breeds bacteria and must be discarded, and this not only causes waste of resources, but also harms the environment.

In order to effectively improve the aforementioned problems, the utility model designs a toothbrush with a replaceable brush head, which mainly comprises a handle portion and a brush head connected to the handle portion; the brush head comprises a table connected with the handle portion and the planting a toothbrush piece provided with bristles; wherein the seat table and the toothbrush piece are matched with a fitting groove and a fitting portion which can be inserted and coupled with each other, so that the toothbrush piece with the bristles can be inserted and coupled to the seat, and A toothbrush that forms a replaceable brush head.

However, the above-mentioned toothbrush replacing the brush head still has the following problems during actual use. Since it is fixed by the groove, the socket is easily loosened after being used for a period of time, and is easily peeled off. Case.

One of the aims of the present invention is to provide a toothbrush with a forward-pushing replacement brush head, which is capable of achieving the lifting and exiting of the brush head by pushing and pushing the arm, thereby increasing the convenience of operation.

In order to achieve the above object, the present invention provides a toothbrush for a front push type replacement brush head, comprising a handle portion, a front portion of a handle portion, a front push mechanism and a brush head, the front portion of the handle portion connecting the handle portion. The front portion of the handle has a receiving platform; the front pushing mechanism includes a trigger arm pivotally connected to the handle portion and a push piece and a clamping piece which are overlapped with each other and pass through the front portion of the handle portion. The driving piece and the fixing piece are driven to move in the front-rear direction; the brush head is replaceably mounted on the receiving table, and one end of the clamping piece is clamped to the brush head and the front part of the handle; The trigger arm will move the clamping piece and the pushing piece toward the brush head, and release the clamping piece, the front part of the handle and the brush head, and the pushing piece pushes the brush head away from the The direction of the platform is retracted.

The creation also has the following effects, and the locking effect can be achieved by the convex hooks of the wrench arm and the grooves of the driven member being mutually engaged. The semi-circular tooth of the trigger arm is meshed with the rack of the driven member to increase the stability of the actuation. A labor-saving effect can be achieved by the elastic hooks being pushed against the inclined surface.
