Detailed Description

The technical solution of the present invention will be described below with reference to the accompanying drawings of the present invention.

The utility model discloses a razor button structure, it includes razor main part 1, and razor main part 1 is provided with trigger device 11. The shaver body 1 is provided with a power device for driving the shaver head, and the trigger device 11 is electrically connected with the power device and used for controlling the operation of the power device. Typically, the triggering device 11 is a microswitch, but may also be another type of switch or control device, such as a magnetic induction switch or the like.

The utility model discloses a razor button structure still includes button 3 and the outer shell lid 2 of being connected with razor main part 1.

Normally, the housing cover 2 is provided with a catch 29, and the shaver body 1 is provided with a catch groove 19; the clips 29 are respectively clipped into the clip grooves 19; the housing cover 2 is detachably attached to the shaver body 1.

The key 3 is hinged with the shell cover 2, the key 3 is provided with a trigger body 31 opposite to the trigger device 11, namely, the key 3 can rotate to trigger the trigger device 11; if the trigger 11 is a microswitch, the key 3 can be rotated to abut against the trigger 11 to trigger the trigger 11. Generally, the trigger body 31 is provided with a trigger protrusion 311 extending inwardly; the trigger protrusion 311 faces the trigger 11.

The utility model discloses a shaver button structure's theory of operation does: in use, as shown in fig. 5, when the key 3 is pressed to rotate the key 3, the trigger body 31 triggers the trigger device 11 to control the shaver.

In the process of pressing the key 3, the key 3 only rotates around the axis of the hinged part of the key 3 and the shell cover 2, and cannot be propped against to rotate and deflect by one side of the trigger device 11, so that the reliability of triggering the trigger device 11 by the key 3 can be improved, and when the pressing area of the key 3 is large, the trigger device 11 can be reliably triggered at any position of the key 3, thereby facilitating the operation of the shaver.

Preferably, the key 3 is hinged to an inner wall of the housing cover 2 (the side of the key hole 21 close to the shaver body 1 is the inner wall). The outer wall of the outer shell cover 2 is not required to be provided with a hinged structure, so that the outer wall of the outer shell cover 2 can be smooth, and hand feeling when the shaver is held is guaranteed.

As an embodiment, the inner wall of the housing cover 2 extends inwards (i.e. towards the shaver body 1) to form the hinge hole 22, and the button 3 is provided with a hinge post 32, and the hinge post 32 is inserted into the hinge hole 22, so that the button 3 is hinged to the inner wall of the housing cover 2.

Further, the housing cover 2 is made of an elastic material (such as ABS plastic, etc.), and the hinge hole 22 is provided with an installation notch 221 communicating with the outside; an included angle between the connecting lines of the two ends of the installation notch 221 and the axis of the hinge hole 22 is an installation notch angle β, and the installation notch angle β is smaller than one hundred eighty degrees. Typically, the mounting notch angle β is greater than one hundred twenty degrees. When the hinge post 32 is inserted into the hinge hole 22, the hinge post 32 can be pressed into the hinge hole 22 from the mounting notch 221 [ the inner wall of the mounting notch 221 is elastically deformed ], so that the key 3 can be conveniently assembled to the housing cover 2.

Further, the shaver main body 1 is provided with a limiting protrusion 222, and the limiting protrusion 222 abuts against the hinge post 32. It can be ensured that when the key 3 is pressed, the hinge post 32 will not fall off from the mounting notch 221, so that the key 3 cannot trigger the triggering device 11.

Further, the key 3 is further fixedly provided with an elastic member 33 made of an elastic material (such as ABS plastic, etc.), and the other end of the elastic member 33 (the other end of the elastic member 33 fixedly connected with the key 3) abuts against the housing cover 2 or the shaver main body 1 (the embodiment of abutting against the shaver main body 1 is not shown in the drawings). The elastic force provided by the elastic member 33 can assist the key 3 to reset, so that the key 3 can be ensured to reset even if the force for driving the key 3 to reset by the trigger device 11 is insufficient, and the hand feeling for pressing the key 3 is better.

Preferably, the elastic member 33 is provided with an elastic limiting hole 331, the inner wall of the housing cover 2 is provided with an elastic limiting post 332 extending inwards, the elastic limiting posts 332 are respectively embedded into the elastic limiting hole 331, so that the elastic member 33 abuts against the inner wall of the housing cover 2, and the elastic member 33 and the elastic limiting post 332 are fixedly connected through interference fit between the elastic limiting post 332 and the elastic limiting hole 331. When the key 3 is assembled on the housing cover 2, the key 3 is moved towards the housing cover 2, after the key 3 is hinged with the housing cover 2, the elastic limit columns 332 are respectively embedded into the elastic limit holes 331, at this time, even if the inner wall of the housing cover 2 is downward, the key 3 can not automatically rotate under the action of self weight, the housing cover 2 is assembled on the shaver body 1 without holding the key 3 by hands, and the housing cover 2 is convenient to assemble on the shaver body 1.
