Description

一种振动剃须刀Vibrating shaver 技术领域Technical field
本发明涉及剃须刀，尤其涉及一种自动开关式振动剃须刀。The invention relates to a shaver, in particular to an automatic switching type vibration shaver.
背景技术Background technique
电动剃须刀(干法剃须刀)通常使用旋转刀头，虽然其可以藉此减少力道控制的程度，但存在剃须不彻底的现象。An electric shaver (dry shaver) usually uses a rotating head, although it can reduce the degree of force control, but there is a phenomenon of incomplete shave.
传统湿法剃须刀的刀头沿着皮肤表面将胡须剃除过程中，当刀头尚未完全切断胡须时，刀头的移动会拉扯到胡须，于胡须完全切断后，胡须才能回复到原先的位置。因此刀头剃除胡须的过程会让使用者产生拉扯胡须的疼痛感。为了解决此间题，因而发展出电动剃须刀及振动式剃须刀。In the process of shaving the beard along the surface of the skin with the blade of the traditional wet razor, when the blade has not completely cut the beard, the movement of the blade will pull the beard. After the beard is completely cut, the beard can return to its original shape. position. Therefore, the process of shaving the beard by the cutter head will cause the user to have a painful sensation of pulling the beard. In order to solve this problem, electric shavers and vibrating shavers have been developed.
振动式剃须刀产生一振动力道给刀头，藉此刀头能在皮肤上以一小段距离快速地来回移动，因此能快速且渐进地切断胡须，进而拉扯胡须的力道较小，所以使用者可具有较为舒适的剃须感，亦即振动式剃须刀较不容易让使用者有传统湿法剃须刀拉扯皮肤的刺痛感。并且，振动式剃须刀可降低刀头与使用者面部皮肤的摩擦系数，同时具备按摩皮肤的作用。因而更加提高了剃须过程的舒适性。The vibrating razor generates a vibration force to the cutter head, whereby the cutter head can move quickly back and forth in a short distance on the skin, so the beard can be cut off quickly and gradually, and the force of pulling the beard is small, so the user It can have a more comfortable shaving sensation, that is, the vibrating razor is less likely to give the user the tingling sensation of the traditional wet razor pulling the skin. In addition, the vibrating razor can reduce the coefficient of friction between the cutter head and the user's facial skin, and at the same time has the function of massaging the skin. Therefore, the comfort of the shaving process is further improved.
一般振动式剃须刀的开关使用传统按键来控制其开关工作；使用传统按键开关控制工作的振动剃须刀，需解决开关表面结构的防水问题，通常在按键表面使用软硅胶与外壳粘贴或注塑方式进行封闭，该方式存在硅胶易老化导致防水性能减弱，以及外观整体性被破坏，视觉感官变差的缺点。Generally, the switch of the vibrating shaver uses traditional buttons to control its switch work; the use of traditional button switches to control the work of the vibrating shaver needs to solve the waterproof problem of the surface structure of the switch. Usually, soft silicone is used on the surface of the button to paste or inject the shell. The method is closed. This method has the shortcomings that the silica gel is easy to age and the waterproof performance is weakened, and the integrity of the appearance is destroyed, and the visual sense becomes worse.
