背景技术Background technique
在日常生活中,人们在使用电动用品时需要人为地为电动用品施加适当的力,在操作过程中,如果存在错误操作导致电动用品受到较大的力,那么就会导致电动用品受到损害或者对使用电动用品的人造成伤害。例如现在比较常见并且使用较为广泛的电动牙刷,由于电动牙刷在用户没有施力的情况下就已经可以产生很强的对牙齿的研磨力,因此用户只需要对电动牙刷施加适当的力就可以达到很好的清洁牙齿的效果,但是用户以往使用普通牙刷养成的习惯或者第一次使用电动牙刷时都会造成施力过大的情况,因此就可能会对口腔中的一些部位造成伤害。因此,在用户使用电动用品时,如何避免由于用户的不正当操作而给用户本身带来伤害这一问题是非常重要的。In daily life, people need to artificially apply appropriate force to the electric equipment when using the electric equipment. During the operation, if there is a wrong operation that causes the electric equipment to be subjected to a large force, the electric equipment will be damaged or damaged.

For example, the more common and widely used electric toothbrushes, because the electric toothbrush can already generate a strong grinding force on the teeth without the user applying force, so the user only needs to apply appropriate force to the electric toothbrush to achieve The effect of cleaning teeth is very good, but the user's habit of using ordinary toothbrushes in the past or using an electric toothbrush for the first time will cause excessive force, so it may cause damage to some parts of the mouth. Therefore, when the user uses the electric appliance, it is very important to avoid the problem of harming the user himself due to the improper operation of the user.
