Embodiment Construction

[0035] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.

[0036] Such as figure 1 Shown is a wearing detection circuit that is prone to false triggers in the prior art, where EMS_OUT1 and EMS_OUT2 are electrode pads, and EMS_CHECK1 is at high level when not wearing; after wearing, EMS_CHECK1 is at low level.

[0037] However, technicians found that since the value of VCC_HV1 will change greatly in a very short period of time, and the frequency of turning on and off of the triode is very high, it is easy to generate interference in the circuit and cause false detection. Specifically, when the user is not wearing it, for the electrode drive circuit terminal, when the CA terminal is closed and the CB terminal is opened, the charge accumulated on the emitter of the first triode will move to VB with the opening of the...

Abstract

The invention discloses a wear detection circuit, a neck massage device and a wear detection method. The wear detection circuit comprises a first input module, a second input module and a comparison module, wherein a first end of the first input module is used for receiving an electrode drive power supply signal; the first end of the second input module is used for receiving an electrode drive detection signal; a first input end of the comparison module is connected with a second end of the first input module; a second input end of the comparison module is connected with the second end of thesecond input module; and the comparison module is used for determining a wear state according to the comparison result of the electrode drive power supply signal and the electrode drive detection signal and outputting a wear detection signal. According to the circuit, the accuracy of detecting the wear state of the neck massage device can be improved, the phenomenon of false triggering when the neck massage device is not worn is avoided and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of massage instruments, in particular to a wearing detection circuit, a neck massage device and a wearing detection method. Background technique [0002] The neck massager uses pulsed electric frequency to transmit to the deep skin, simulating a variety of simulated massage techniques to achieve the effect of deep relaxation of the cervical spine. [0003] In the related art, for the easy-to-wear neck massager, the electrode assembly of this type of massager has a small contact area with the skin. On the basis of not changing the structure, due to the difference in the neck of different users, the electrode assembly is in contact or has not yet Prone to false triggering on contact and stinging. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to propose a wearing detect...
