Electric toothbrush

Abstract

The invention discloses an electric toothbrush. The electric toothbrush comprises a brush holder and a brush head, wherein the brush head is connected to the brush holder; the brush holder comprises amotor, a pressure sensing soft board and a main board; the end, far away from the motor, of a motor shaft of the motor is connected to the brush head; the pressure sensing soft board is arranged on the side, facing the same direction as bristles of the brush head, of the end, close to the motor, of the motor shaft of the motor; the motor shaft is fixedly connected to a collecting end on the pressure sensing soft board; and the main board receives micro-deformation of the motor shaft collected by the collecting end of the pressure sensing soft board. The electric toothbrush has the advantagesthat micro-deformation of the motor shaft in the working process of the electric toothbrush is collected through the pressure sensing soft board fixedly connected to the motor shaft so that the accuracy of micro-deformation collection is improved, then the main board receives micro-deformation information of the motor shaft so as to determine whether the micro-deformation information is matched with the current working mode or not, and therefore teeth of a user can be better protected, and the tooth brushing experience of the user is effectively improved.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to an electric toothbrush. Background technique [0002] At present, electric toothbrushes are becoming more and more popular in human life. With the promotion of the market, traditional electric toothbrushes can no longer meet people's needs. People hope that toothbrushes can become more and more intelligent, and can better provide our teeth better service. [0003] Conventional electric toothbrush, one is to set the corresponding working mode by itself, the user only needs to press the fixed button to select the current working mode that he wants to use; the other is the smart toothbrush, which is mainly used to increase the corresponding induction device or Connect the corresponding smart devices to improve the user experience. For a class of smart toothbrushes that add corresponding sensing devices, a corresponding pressure sensor is usually installed in the electric ...

Problems solved by technology

[0004] For the electric toothbrush mentioned above, the fixed working mode in the first electric toothbrush can meet the needs of the public to a certain extent, but the fixed working mode will make the user experience poor after long-term use. For an electric toothbrush with a pressure sensor added to a smart toothbrush, due to its complex mechanism in the existing solution, the design cost of the electric toothbrush is relatively high, and the arrangement of the pressure sensor makes the pressure detection not accurate enough
