Example Embodiment

[0030] The present invention will be described in detail below in conjunction with the drawings. Throughout the drawings, similar reference numerals indicate similar components.

[0031] Although the terms first, second, etc. are used in this specification to describe the operating parameters or multiple components or components of the electric toothbrush, these operating parameters or components or components should not be limited by these terms. These terms are only used to distinguish one operating parameter or element or component from another operating parameter or element or component, and do not include "sequence". Therefore, the mutual conversion of ordinal numbers to express those operating parameters, elements or components discussed below does not go beyond the concept and scope of the present invention.

[0032] In addition, the term "and / or" used in this application includes any and all combinations of one or more of the listed related terms.

Abstract

An electric toothbrush comprises a brush part and a handle part which can be detached, wherein the brush part comprises a brush head and bristles, the handle part comprises a motor, and a transmission mechanism, an integrated circuit (IC) and a printed circuit board assembly (PCBA) which are connected with the motor, the PCBA comprises part of a power module, a detection module, a drive module, a control module, an indication module and a command module, the detection module comprise one or a plurality of voltage transducers, the characteristic that a direct current permanent magnetic micro-motor has different working currents under different loads is utilized, the voltage transducers respectively detect the voltage value in an operation state and the voltage value in an initial state that the brush head rotates but the bristles are not in contact with teeth to be brushed, the difference of the two voltage values is obtained, when the force which is applied to the brush head by a user is larger than a set value, the detection module detects that the voltage difference of the voltage transducers is larger than the set value, the IC sends out a signal, and a corresponding pressure indication element in the indication module, which is used for reflecting pressure sends out an indication to prompt the user that the force which is applied to the brush head is too large. The electric toothbrush provided by the invention has various working modes, has the functions of working mode converting, reminding and memorizing, pressure warning and indicated pressure warning, charging and charging indicating, battery capacity indicating, electric quantity indicating and the like. The electric toothbrush can complete various functions.

Description

technical field [0001] The present invention relates to an electric toothbrush, more specifically, relates to an electric toothbrush with multiple functions, which has multiple working modes, and has functions such as working mode conversion and memory function, time reminder and power indicator. Background technique [0002] Because electric toothbrushes have obvious advantages in cleaning teeth compared with manual toothbrushes and can have other auxiliary functions, it is more and more popular among users. Therefore, electric toothbrushes with different functions have been developed in recent years. [0003] A light emitting electric toothbrush is disclosed in U.S. 6,954,961 B2, which gives a visible signal to the user when sufficient brushing force has been applied by the user. The electric toothbrush comprises: a handle portion and a brush head portion; a plurality of light sources disposed adjacent to each other with respect to the toothbrush body such that a user of ...
