Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
Fig. 1 shows a wearing detection circuit susceptible to false triggering in the prior art, in which EMS _ OUT1 and EMS _ OUT2 are electrode pads, and when not worn, EMS _ CHECK1 is at a high level; after wearing, EMS _ CHECK1 is low.
However, the skilled person finds that the VCC _ HV1 value varies greatly in a very short time, and the on/off frequency of the transistor is very high, so that the circuit is prone to generate interference and cause false detection. Specifically, when the user is not wearing the electrode driving circuit, when the CA terminal is off and the CB terminal is on, the charges accumulated on the emitter of the first triode will move to the VB terminal with the CB terminal being on, the voltage difference between VCC _ HV1 and VB terminal is not large (the voltage at VCC _ HV1 is slightly larger than the voltage at VB terminal due to voltage drop), EMS _ OUT1 and EMS _ OUT2 are not connected, and after the capacitor C2 in fig. 1 is fully charged, the fifth triode Q5 will be triggered to be turned on, and the EMS CHECK1 signal will be sent OUT by mistake, so as to cause misoperation, but actually, the user is not wearing the electrode driving circuit, and an undesirable condition, such as a pricking phenomenon, will occur.
In view of the above problems, the embodiment of the present invention provides a wearing detection circuit, which can improve the accuracy of detecting the wearing state of a neck massage device, avoid the false triggering phenomenon when the neck massage device is not worn, and improve the user experience.
A wear detection circuit according to an embodiment of the first aspect of the present invention is described below with reference to fig. 2.

In an embodiment, the wear detection circuit 10 is used in a neck massage apparatus, and is electrically connected to the electrode driving circuit, so that the electrode driving circuit can drive the electrodes to work according to the output signal of the wear detection circuit. As shown in fig. 2, a first terminal of the first input module 1 is connected to a power supply terminal of the electrode driving circuit, namely, a VCC _ HV1 terminal, for receiving an electrode driving power supply signal; the first end of the second input module 2 is connected with a wearing detection end of the electrode driving circuit, namely a VB end, so as to receive the electrode driving detection signal; the first input end of the comparison module 3 is connected with the second end of the first input module 1, and the second input end of the comparison module 3 is connected with the second end of the second input module 2, so as to determine the wearing state according to the comparison result of the electrode driving power supply signal and the electrode driving detection signal, and output the wearing detection signal. The electrode driving power supply signal can be understood as whether an electric signal for supplying power to the electrode exists or not, and the electrode driving detection signal can be understood as whether the electrode is communicated or not.
In operation, the first input module 1 receives an electrode driving power supply signal provided by a power supply terminal, and is transmitted to the comparison module 3 through the first input end, and the second input module 2 receives the electrode driving detection signal provided by the wearing detection end and is transmitted to the comparison module 3 through the second input end, and then the comparison module 3 compares the electrode driving power supply signal with the electrode driving detection signal, determines the wearing state according to the comparison result, namely, the circuit of the embodiment of the invention compares the driving power supply signal with the driving detection signal through the comparison module 3, namely, the phase difference amplitude of the two is compared, and only when the phase difference reaches a certain amplitude value, the signal of the comparison module 3 is turned over, namely, the wearing state is switched. Therefore, the comparison module 3 determines the wearing state according to the comparison result, so that the signal of the driving electrode can be output only when the wearing state is achieved, and the signal of the driving electrode cannot be output under other conditions, thereby preventing the false triggering behavior when the wearing state is not achieved, avoiding the pricking phenomenon and ensuring the use safety.
In an embodiment, the comparison module 3 determines the wearing state according to the comparison result of the electrode driving power supply signal and the electrode driving detection signal, and determines whether the user wears the electrode by comparing the magnitudes of the two signals, specifically, if the electrode driving power supply signal is higher than the electrode driving detection signal, it is determined that the electrode is not worn, that is, the electrode is not connected, then the unworn detection signal is output, and the electrode is not driven to operate, or, if the electrode driving power supply signal is lower than the electrode driving detection signal, it is determined that the electrode is worn, that is, the electrode is connected, then the worn detection signal is output, and the electrode is driven to operate.
According to the wearing detection circuit 10 provided by the embodiment of the invention, the first input module 1 is used for receiving the electrode driving power supply signal, the second input module 2 is used for receiving the electrode driving detection signal, the comparison module 3 is used for comparing the electrode driving power supply signal with the electrode driving detection signal so as to determine that the electrode is not worn or worn according to the comparison result, and outputting the wearing detection signal, and the driving power supply signal is compared with the driving detection signal, namely the phase difference amplitude of the electrode driving power supply signal and the driving detection signal is compared, so that the signal of the comparison module 3 is turned over only when the phase difference reaches a certain amplitude value, namely the wearing state is switched, interference can be filtered, the false triggering phenomenon cannot occur, the wearing state detection accuracy is improved, the use safety is ensured, and the user experience is improved.
In an embodiment, as shown in fig. 2, the first input module 1 may include a first resistance unit R1 and a second resistance unit R2. The first end of the first resistance unit R1 is used for receiving an electrode driving power supply signal; the first end of the second resistance unit R2 is connected to the second end of the first resistance unit R1, the second end of the second resistance unit R2 is grounded, a first node p is arranged between the first end of the second resistance unit R2 and the second end of the first resistance unit R1, and the first node p is connected to the first input end of the comparison module 3, so as to realize the acquisition of the electrode driving power supply signal. The second resistance unit R2 can perform a voltage dividing function, further reduce the possibility of breakdown of the device, and perform a voltage control function to control the voltage at the first node p.
In an embodiment, as shown in fig. 2, the second input module 2 may include a third resistance unit R3, a fourth resistance unit R4, and a first capacitance unit C1. Wherein, the first end of the third resistance unit R3 is used for receiving the electrode driving detection signal; a first end of the fourth resistor unit R4 is connected to a second end of the third resistor unit R3, a second end of the fourth resistor unit R4 is grounded, a second node q is formed between the first end of the fourth resistor unit R4 and the second end of the third resistor unit R3, and the second node q is connected to a second input end of the comparison module 3; the first end of the first capacitor unit C1 is connected with the first end of the third resistor unit R3, and the second end of the first capacitor unit C1 is grounded, so as to collect the electrode driving detection signal. The fourth resistance unit R4 can perform a voltage dividing function, further reduce the possibility of breakdown of the device, and perform a voltage control function to control the voltage at the second node q. And the first capacitor unit C1 can play a role in filtering, so that interference is avoided, and the accuracy of the detection signal is improved.
In an embodiment, the first resistance unit R1 and the second resistance unit R2 are configured to divide the electrode driving power supply signal to obtain a first acquisition signal, and the first node p is configured to output the first acquisition signal; and the third resistance unit R3 and the fourth resistance unit R4 are used for analyzing the electrode driving detection signal to obtain a second acquisition signal, and the second node q is used for outputting the second acquisition signal. Further, the comparison module 3 is configured to determine that the user is not wearing the wearable device and output a detection signal that the user is not wearing the wearable device when the first acquisition signal is higher than the second acquisition signal, or determine that the user is wearing the wearable device and output a detection signal that the user is wearing the wearable device when the first acquisition signal is lower than the second acquisition signal.
For example, the comparing module 3 may include an integrated amplifier, as shown in fig. 2, wherein the voltage at the first node p may be understood as a first collected signal, the voltage at the second node q may be understood as a second collected signal, and the comparing module 3 determines the wearing state by comparing the magnitudes of the voltages at the two nodes, and outputs the wearing detection signal. Specifically, the same-direction input end of the integrated amplifier is respectively connected with one end of the first resistor unit R1 and one end of the second resistor unit R2, and the reverse-direction input end of the integrated amplifier is respectively connected with one end of the third resistor unit R3 and one end of the fourth resistor unit R4, so as to control the voltage drop proportion and realize that the voltage difference between the first node p and the second node q is obviously different. Therefore, the wearing detection circuit of the embodiment of the invention is arranged to enable the EMS CHECK1 to output high level and not output pulse signals when the electrode is in an unworn state, namely the electrode is not communicated, and Vp is greater than Vq; if the electrode is in a wearing state, namely the electrode is connected, and Vp is less than Vq, the EMS CHECK1 outputs a low-level signal. Therefore, the comparison module 3 compares the first collected signal with the second collected signal, that is, compares the voltages at the first node p and the second node q, and determines whether the wearable module is in a wearing state according to the comparison result, so as to avoid the false triggering phenomenon when the wearable module is not worn.
It should be noted that fig. 2 merely shows an example of the circuit structure of the wear detection circuit 10, and other modified circuit structures based on this circuit structure are also within the protection scope of the embodiments of the present invention.
Fig. 3 is a diagram showing a waveform diagram generated by the circuit shown in fig. 1 in the prior art, and fig. 3(b) is a diagram showing a waveform diagram generated by the wear detection circuit in the embodiment of the present invention, as can be seen by comparing the two waveform diagrams, when the circuit shown in fig. 1 in the prior art is used, a trailing phenomenon exists in a low-level portion of the waveform, that is, when the circuit is not worn actually, an error trigger phenomenon occurs due to an error signal EMSCHECK1 caused by signal delay; when the circuit provided by the embodiment of the invention is adopted, the detection signal is a rectangular wave, the output of low level when the circuit is not worn is detected, and the output of high level when the circuit is worn is detected, so that the signal trailing phenomenon cannot occur, namely the false triggering phenomenon does not occur. Namely, the wearing detection circuit 10 of the embodiment of the invention can achieve the effects of adjusting distortion and preventing signal errors, and improve the accuracy and stability of signal detection.
Therefore, according to the wearing detection circuit 10 of the embodiment of the present invention, the comparison module 3 compares the electrode driving power supply signal and the electrode driving detection signal to determine whether the user wears the electrode, and outputs the worn detection signal when the user is determined to wear the electrode, or outputs the unworn detection signal when the user is determined to unworn, that is, the electrode is driven only in the wearing state, so that the false triggering phenomenon when the user does not wear the electrode can be avoided, the use safety is ensured, and the user experience is improved.

In the embodiment, when the neck massage device is not worn, the voltage of the power supply end is greater than the voltage of the wearing detection end, and then the voltages at the two end points are distinguished through the wearing detection circuit 10 to determine whether a user wears the neck massage device, specifically, when the first electrode 4 and the second electrode 5 are not communicated, the neck massage device is in an unworn state, at this time, an electrode driving power supply signal detected by the wearing detection circuit 10 is greater than an electrode driving detection signal, namely, the voltage of the power supply end is greater than the voltage of the wearing detection end, and the unworn detection signal is output to the controller 7, and the controller 7 controls the electrode driving circuit not to work, namely, the first electrode 4 and the second electrode 5 are not driven to run; when the first electrode 4 is communicated with the second electrode 5, namely, the wearing state is achieved, the electrode driving power supply signal detected by the wearing detection circuit 10 is smaller than the electrode driving detection signal, namely, the voltage of the power supply end is smaller than the voltage of the wearing detection end, the wearing detection signal is output to the controller 7, and the controller 7 controls the electrode driving circuit to work, namely, the first electrode 4 and the second electrode 5 are driven to run, so that the neck massage effect is achieved.
