The embodiment of the application discloses massage equipment, which can reduce the pricking feeling generated in the electric stimulation massage process. The following are detailed below.

Referring to fig. 1, fig. 1 is a schematic view of a mechanical structure of a massage apparatus according to an embodiment. As shown in fig. 1, the massage device 10 may include at least two electrode pads 110, and the electrode pads 110 may be applied to a body part of the user, such as the skin, joints, etc., of the user, to provide massage services. In an embodiment of the present application, each electrode sheet set 110 may include at least two electrode sheets 112, and the electrode sheets may output an electrical signal (e.g., a current signal) to act on a human body part to generate an electrical stimulation massage effect. In another embodiment of the present application, two electrode sheet groups may share an electrode sheet. For example, a first electrode sheet set may include electrode sheet a and electrode sheet C, a second electrode sheet set may include electrode sheet B and electrode sheet C, and the first electrode sheet set and the second electrode sheet set share electrode sheet C. Thus, the massage device may comprise at least three electrode pads.

Referring to fig. 2, fig. 2 is a schematic circuit structure diagram of a massage apparatus according to an embodiment. As shown in fig. 2, the massage device 10 may include a first electrode plate group 110a, a second electrode plate group 110b, a control circuit 120, and a first pulse output circuit 131 and a second pulse output circuit 132. The first electrode sheet group 110a may include at least two first electrode sheets 112 a; the second electrode sheet set 110b may include at least two second electrode sheets 112 b. The control circuit 120 may be electrically connected to the first pulse output circuit 131 and the second pulse output circuit 132, respectively, the first pulse output circuit 131 may be electrically connected to at least two electrode pads 112a included in the first electrode pad group 110a, and the second pulse output circuit 132 may be electrically connected to at least two electrode pads 112b included in the second electrode pad group 110 b. Each pulse output circuit can generate pulse current under the drive of the input drive voltage and output the pulse current to at least two electrode plates. The pulse current output by the at least two electrode slices can act on a human body part (such as skin) to generate stimulation so as to realize the function of electric stimulation massage. It should be noted that, although not shown, the massage device may include more pulse output circuits and electrode plate sets, and each electrode plate set corresponding to a pulse output circuit may include at least two electrode plates. For convenience of description, the following description will be given by taking an example in which the pulse control circuit includes two pulse output circuits and four electrode plates.

In the embodiment of the present application, the control circuit 120 may be configured to detect the conduction state of each pulse output circuit. In the embodiment of the present application, the control circuit 120 may apply a driving voltage to the pulse output circuits electrically connected to the respective electrode pads, so that the pulse output circuits output pulse signals under the driving of the driving voltage. When the massage equipment is in different wearing states, the load resistance of the massage equipment can change, so that the pulse signal output by the pulse output circuit is unstable, and the conduction state of the pulse output circuit is influenced. When the massage equipment is not worn or worn badly, the attaching state of the electrode plate and the human body can be in an abnormal attaching state, and the abnormal attaching state can refer to the state that the electrode plate and the human body are not completely attached. Optionally, the abnormal attaching state can be further divided into an attaching poor state and an non-attaching state; wherein, the poor bonding state can refer to the state that the electrode plate is bonded with the skin of a human body but the bonding area is too small; the non-bonded state may refer to a state in which the electrode sheet is not bonded to the skin of the human body. When the massage equipment is worn well, the attaching state of the electrode plate and the human body may be in a normal attaching state, and the normal attaching state may refer to a state that the electrode plate is completely attached to the human body. Because the pulse output circuit forms a loop with the human body through the electrode plate group, the bonding state of the electrode plate group and the human body influences the conduction state of the pulse output circuit.

In the embodiment of the present application, the control circuit 120 may determine an effective pulse signal output by the pulse output circuit, where the effective pulse signal may be a stable pulse signal output by the pulse output circuit, such as a pulse voltage output by the pulse output circuit and meeting a certain voltage condition, or a pulse current output by the pulse output circuit and meeting a certain current condition. By counting the effective pulse signals output by the pulse output circuit, the on state of the pulse output circuit can be determined according to the number of the effective pulse signals. Optionally, when the number of the effective pulse signals output by the first pulse output circuit is smaller than the first threshold, it may be determined that the first electrode sheet electrically connected to the first pulse output circuit is in an abnormal conduction state with the human body.

In the embodiment of the present application, the control circuit 120 may be configured to adjust the driving voltage input to the first pulse output circuit 131 to the first voltage when the first pulse output circuit 131 is detected to be in the abnormal conduction state. The first pulse output circuit 131 is configured to generate a first pulse current under the driving of the first voltage, and output the first pulse current to the corresponding first electrode sheet group 110a, so that the first electrode sheet 112a included in the first electrode sheet group 110a outputs the first pulse current. It should be noted that the first pulse output circuit 131 may be any one of the pulse output circuits included in the massage apparatus.

The first voltage may be lower than a driving voltage corresponding to the lowest output gear of the massage device, and the first pulse output circuit 131 may be connected to the first electrode plate group 110 a. When one or more first electrode sheets 112a included in the first electrode sheet group 110a are in an abnormal fit state with a human body, the first pulse output circuit may be in an abnormal conduction state. Optionally, the electrical stimulation massage operation performed by the massage device may include a plurality of different working shifts, and the different working shifts may respectively correspond to different driving voltages, so as to generate different electrical stimulation massage effects. Optionally, the higher the working gear is, the higher the corresponding driving voltage may be, so that the pulse output circuit may be driven to generate a larger pulse current, so that the massage apparatus generates a stronger electric stimulation massage effect.

The first electrode sheet 112a included in the first electrode sheet group 110a may be any one of electrode sheets included in the massage device, and when the first pulse output circuit 131 is in an abnormal on state, if a normal driving voltage is continuously input to the first pulse output circuit 131, a pulse current output by the first pulse output circuit 131 may cause a pricking feeling to a user. However, if the pulse current output by the first pulse output circuit 131 is directly cut off, when the user uses the massage apparatus again, the user needs to manually restart the massage apparatus to reapply the driving voltage to the first pulse output circuit 131, so that the first pulse output circuit 131 outputs the pulse current again, the current signal is transmitted through the electrode pad again, and the electrical stimulation massage operation is resumed, which may cause inconvenience for the user.

Therefore, in the embodiment of the present application, when the first pulse output circuit 131 is in the abnormal conduction state, if the driving voltage input to the first pulse output circuit 131 is adjusted to the first voltage, the first pulse output circuit 131 can generate a weak first pulse current under the driving of the first voltage, and the weak first pulse current is not sensed by the human body, so that the electric stimulation pain feeling can be prevented from being generated in the electric stimulation massage process. Further, the bonding state of the electrode sheet to the human body can be continuously detected by the pulse signal output from the first pulse output circuit 131. Meanwhile, the pulse current output by the first pulse output circuit 131 in the abnormal conduction state is small, so that excessive electric quantity loss is avoided, and the cruising ability of the massage equipment can be guaranteed.

In one embodiment, please refer to fig. 3, fig. 3 is a schematic circuit structure diagram of another massage apparatus disclosed in the embodiments of the present application. As shown in fig. 3, the massage device 10 may further include a timer 140, and the timer 140 may be electrically connected to the control circuit 120.

The timer 140 is configured to detect a duration of the first pulse output circuit 131 in the abnormal on state, and send a first trigger signal to the control circuit 120 when the duration of the first pulse output circuit 131 in the abnormal on state reaches a first duration. The first time period may be set according to actual requirements, for example, the range of the first time period may be set to be within 5s (seconds) to 30s, and may be set to be 5s, 10s, 15s, 20s, 25s, and 30s, but is not limited thereto. The user sometimes has some slight neck to rotate the action, may lead to transient abnormal conduction, but in this case if adjust driving voltage immediately can disturb user's normal use, consequently will adjust driving voltage again after the abnormal conduction state lasts for the first time, can avoid frequently disturbing the user, promote user experience.

The control circuit 120 may also be configured to adjust the driving voltage input to the first pulse output circuit 131 to a first voltage according to the first trigger signal. When the duration of the abnormal on state of the first pulse output circuit 131 reaches the first duration, the driving voltage of the first pulse output circuit 131 is adjusted to the first voltage, so that a weak pulse current is output through the first pulse output circuit 131.

In one embodiment, the control circuit 120 may be further configured to adjust the driving voltage input to the second pulse output circuit 132 to the second voltage when the second pulse output circuit 132 is detected to be in the normal on state. The second pulse output circuit 132 may be configured to generate a second pulse current under the driving of the second voltage, and output the second pulse current to the corresponding second electrode sheet group 110b, so that the second electrode sheet 112b included in the second electrode sheet group 110b outputs the second pulse current.

The second voltage may be a driving voltage corresponding to a current operating range of the massage device. Because the massage equipment comprises at least two pulse output circuits, part of the electrode plates possibly are in an abnormal attaching state with a human body, and the other part of the electrode plates possibly are in a normal attaching state. The second electrode sheet group 110b corresponding to the second pulse output circuit 132 described above may include a second electrode sheet 112b different from the first electrode sheet 112 a. The second electrode sheets 112b included in the second electrode sheet group 110b may be in a normal fit state with the human body, and then the second pulse output circuit 132 may be in a normal on state. At this time, the driving voltage input to the second pulse output circuit 132 may be adjusted to a second voltage, which may be a driving voltage corresponding to the current operating range of the massage device.

Optionally, the massage device 10 may further include a gear selection key, the user may select, through the gear selection key provided on the massage device, an operating gear to be used from a plurality of operating gears provided by the massage device as a currently selected operating gear, and the control circuit 120 may determine, when it is detected that a certain gear selection key is pressed, an operating gear corresponding to the gear selection key as the currently selected operating gear of the user. Alternatively, the massage device 10 may also include a communication module, through which the massage device can establish a communication connection with a mobile terminal such as a smartphone. The user can select a working gear to be used from the plurality of working gears as a currently selected working gear through the mobile terminal with communication connection, and the communication module can receive the currently selected working gear of the user sent by the mobile terminal.

In the embodiment of the present application, the control circuit 120 can control the second pulse output circuit 132 in the normal on state to output a normal pulse current, so as to normally perform the electrical stimulation massage operation by attaching a normal electrode sheet set; and controlling the first pulse output circuit 131 in the abnormal conduction state to output a weak pulse current so as to prevent the electrode sheet attached abnormally from generating an electric prick feeling, and continuously detecting the conduction state of the first pulse output circuit 131 through the weak pulse current. Through discerning the pulse output circuit that is in different conducting state to adjust corresponding pulse output circuit's drive voltage into different voltages, both can avoid being in the electrode slice of abnormal laminating state and produce the electrical stimulation sense of pain, can also continue to provide the electro photoluminescence massage effect through laminating normal electrode slice, avoid only partial pulse output circuit can't normally switch on and lead to whole massage equipment stop work.

In one embodiment, the control circuit 120 may be further configured to continue to detect the on state of the first pulse output circuit 131 after adjusting the driving voltage input to the first pulse output circuit 131 to the first voltage; and adjusting the driving voltage input to the first pulse output circuit 131 from the first voltage to the third voltage upon detecting that the on state of the first pulse output circuit 131 is switched from the abnormal on state to the normal on state. The first pulse circuit 131 is further configured to generate a third pulse current under the driving of the third voltage, and output the third pulse current to the first electrode sheet group 110a, so that the first electrode sheet 112a included in the first electrode sheet group 110a outputs the third pulse current.

The third voltage may be a driving voltage corresponding to the first pulse output circuit in the currently selected operating range. The control circuit 120 may continue to detect the on state of the first pulse output circuit 131 through the weak current output from the first pulse output circuit 131 after adjusting the driving voltage of the first pulse output circuit 131 to the first voltage. When detecting that the first pulse output circuit 131 is restored to the normal on state, the control circuit 120 may adjust the driving voltage input to the first pulse output circuit 131 to the third voltage, that is, when detecting that the first pulse output circuit 131 is restored to the normal on state again, the control circuit may automatically adjust the driving voltage of the first pulse output circuit 131 from the first voltage to the third voltage, so that the first pulse output circuit 131 restores to output the normal pulse current, and the massage apparatus may normally perform the electrical stimulation massage operation without manually restarting the massage apparatus by the user, thereby simplifying the user operation and improving the operation convenience.

In one embodiment, the timer 140 may be further configured to detect a duration of each pulse output circuit in the abnormal conduction state, and send the second trigger signal to the control circuit 120 when the duration of each pulse output circuit in the abnormal conduction state exceeds a second duration.

The control circuit 120 is further configured to electrically disconnect each pulse output circuit from the power supply according to the second trigger signal. If the duration of each pulse output circuit in the abnormal conduction state is too long, for example, exceeds the second duration, the massage device may not be worn for a long time (for example, the massage device is removed). The second time period may be set according to actual requirements, such as 5 minutes, 10 minutes, etc., but is not limited thereto. In order to reduce unnecessary power consumption, the control circuit 120 may disconnect the path between the power supply and each pulse output circuit to stop the power supply. The control circuit 120 may disconnect the power supply from each pulse output circuit by, for example, turning off or entering a sleep mode, but is not limited thereto.

In one embodiment, the control circuit 120 is further configured to adjust the driving voltage input to each pulse output circuit to the driving voltage corresponding to each pulse output circuit in the currently selected operating range when it is detected that each pulse output circuit is in the normal on state. If the pulse output circuits are detected to be in the normal conduction state, the massage equipment can normally execute the electric stimulation massage operation corresponding to the currently selected working gear. The currently selected working gear may need to control different pulse output circuits to output pulse currents at different driving voltages, so that different electrode plate sets perform different electrical stimulation massage operations. Therefore, the control circuit 120 can adjust the driving voltage of each pulse output circuit to the driving voltage corresponding to each pulse output circuit in the currently selected operating gear according to the indication of the currently selected operating gear, so as to achieve the electrical stimulation massage effect corresponding to the currently selected operating gear.

In one embodiment, the control circuit may detect the conduction state of each pulse output circuit through a wear detection circuit electrically connected to the control circuit. Referring to fig. 4, fig. 4 is a schematic circuit structure diagram of another massage apparatus disclosed in an embodiment. As shown in fig. 4, the massage apparatus 40 may include a control circuit 410, a boosting circuit 420, a wear detection circuit 430, a first pulse output circuit 440, a second pulse output circuit 450, and a timer 460. The output terminal of the boost circuit 420 may be electrically connected to the input terminals of the first pulse output circuit 440 and the second pulse output circuit 450, respectively. The massage device 400 further includes at least two first electrode pads 442 electrically connected to the output of the first pulse output circuit 440, and at least two second electrode pads 452 electrically connected to the output of the second pulse output circuit 450. Wherein, the output terminal of the control circuit 410 can be electrically connected to the input terminal of the boosting circuit 420. The outputs of the first pulse output circuit 440 and the second pulse output circuit 450 may also be electrically connected to the inputs of the wear detection circuit 430, respectively. An output of wear detection circuit 430 may be electrically connected to an input of control circuit 410. The input of the control circuit 410 may also be electrically connected to the output of the timer 460. It should be noted that the boost circuit 420 may be a module integrated in the control circuit 410; alternatively, as shown in fig. 4, the boost circuit 420 may be physically independent of the control circuit 410.

The control circuit 410 may output a pulse signal corresponding to the currently selected gear to the voltage boost circuit 420, and the voltage boost circuit 420 may output a driving voltage, which is an input voltage of the first pulse output circuit 440 and the second pulse output circuit 450, to the first pulse output circuit 440 and the second pulse output circuit 450, respectively, according to the received pulse signal. The first pulse output circuit 440 generates a pulse current driven by the driving voltage output from the boosting circuit 420, and outputs the pulse current to the first electrode pad 442, which flows through a load (a user when wearing the device). Similarly, the second pulse output circuit 450 may output a pulse current flowing through the load to the second electrode pad 452 under the driving of the driving voltage output from the voltage boost circuit 420.

The wear detection circuit 430 may be configured to detect the number of valid pulse signals output by each pulse output circuit, and send the number of valid pulse signals output by each pulse output circuit to the control circuit 410. Meanwhile, the timer 460 may start timing to time the duration of the detection of the number of valid pulse signals output by each pulse output circuit by the wear detection circuit 430; when the timer 460 detects that the duration reaches the third duration, a third trigger signal may be sent to the wear detection circuit 430. The third time period may be set according to actual requirements, such as 100ms (milliseconds), 240ms, 500ms, and the like, but is not limited thereto. The wearing detection circuit 430 may send the number of valid pulse signals output by each pulse output circuit detected in the third duration to the control circuit 410 according to the third trigger signal when receiving the third trigger signal.

The control circuit 410 may be configured to determine the on-state of each pulse output circuit based on the number of valid pulse signals output by each pulse output circuit. For example, the wear detection circuit 430 may detect the stable pulse signal output by the first pulse output circuit 440, generate a feedback signal, and send the feedback signal to the control circuit 410. The feedback signal may include a count result of the wear detection circuit 430 on the stable pulse signal output by the first pulse output circuit 440, i.e., the number of valid pulse signals.

In one embodiment, the wear detection circuit 430 may also be used to determine whether the pulse signal output each time by each pulse output circuit is a valid pulse signal; and accumulating the number of the signals which are determined to be the effective pulse signals and output by each pulse output circuit in the third time length to obtain the number of the effective pulse signals output by each pulse output circuit.

In one embodiment, wear detection circuit 430 may include a comparator and a counter electrically connected to the comparator, wherein:

a comparator for obtaining a divided voltage of the pulse output circuit each time the pulse output circuit outputs the pulse signal, the divided voltage being determined by a reflux voltage of the pulse output circuit, the reflux voltage being generated after the driving voltage is input to the pulse output circuit; the comparator is used for comparing the divided voltage with the reference voltage, and outputting a fourth trigger signal to the counter if the divided voltage is greater than the reference voltage; the reference voltage may be a voltage value set according to experimental data or an empirical value, for example, 45V (volts), 40V, or the like. In some embodiments, different gears may respectively correspond to different reference voltages, and the reference voltages may be set according to actual requirements. Optionally, the higher the shift position is, the larger the corresponding reference voltage may be, and the stronger the current signal output by the electrode plate may be. In some embodiments, the reference voltage may also be obtained by dividing the return voltage by a voltage dividing resistor.

And the counter can be used for adding 1 to the signal number of the effective pulse signals output by the pulse output circuits when the fourth trigger signal is received, so that the number of the effective pulse signals output by each pulse output circuit can be detected.

For example, please refer to fig. 5, fig. 5 is a schematic circuit structure diagram of another massage apparatus disclosed in the embodiment of the present application. As shown in fig. 5, the wear detection circuit 430 may include a comparator 431 and a counter 433, the comparator 431 being electrically connected to the counter 433. In addition, the wear detection circuit 430 may further include a first voltage divider circuit 432 and a second voltage divider circuit 434, wherein the output terminal of the voltage boost circuit 420 may be electrically connected to the input terminal of the second voltage divider circuit 434, and the output terminals of the first pulse output circuit 440 and the second pulse output circuit 450 may be electrically connected to the input terminal of the first voltage divider circuit 432, respectively. As a specific embodiment, the ground terminals of the first pulse output circuit 440 and the second pulse output circuit 450 may be respectively connected to the input terminal of the first voltage divider circuit 432, and the first voltage divider circuit 432 may collect the return voltage generated by the returned pulse current first and then perform grounding.

The first voltage dividing circuit 432 may include two first voltage dividing resistors connected in series with the first pulse output circuit 440 and the second pulse output circuit 450, respectively. Taking the first pulse output circuit 440 as an example, the first voltage divider resistor may divide the return voltage of the first pulse output circuit 440 to obtain a first divided voltage. The second voltage dividing circuit 434 may include two second voltage dividing resistors connected in series with the first pulse output circuit 440 and the second pulse output circuit 450, respectively. Taking the first pulse output circuit 440 as an example, the driving voltage output from the voltage boost circuit 420 to the first pulse output circuit 440 may be divided by the second voltage dividing resistor to obtain the first reference voltage.

Referring to fig. 6, fig. 6 is a schematic structural diagram of a comparator 431 disclosed in the embodiment of the present application. An EMS _ check input terminal of the comparator 431 may be electrically connected to an Output terminal of the first voltage divider circuit 432, an EMS _ HV _ VREF input terminal of the comparator 431 may be electrically connected to an Output terminal of the second voltage divider circuit 434, and an Output terminal of the comparator 431 may be electrically connected to an input terminal of the counter 434. The EMS _ check input terminal may input the divided voltage output from the first voltage dividing circuit 432 to the comparator 431, the EMS-HV _ VREF input terminal may input the reference voltage output from the second voltage dividing circuit 434 to the comparator 431, and the comparator 431 may compare the divided voltage with the reference voltage and transmit a fourth trigger signal to the counter 434 when the divided voltage is greater than the reference voltage. The counter 434 may add 1 to the signal number of the valid pulse signal output by the first pulse output circuit 440 when receiving the fourth trigger signal.

Similarly, the second pulse output circuit 450 may be electrically connected to the first voltage dividing resistor of the first voltage dividing circuit, so as to divide the return voltage of the second pulse output circuit 450 by the first voltage dividing resistor, thereby obtaining a second divided voltage. And, the second pulse output circuit 450 may further be electrically connected to a second voltage dividing resistor of the second voltage dividing circuit, so as to divide the driving voltage output from the voltage boosting circuit 420 to the second pulse output circuit 450 by the second voltage dividing resistor, so as to obtain a second reference voltage. The comparator 431 compares the second divided voltage with the second reference voltage, and sends a fourth trigger signal to the counter 434 if the second divided voltage is greater than the second reference voltage, so that the counter 434 adds 1 to the number of signals of the effective pulse signal output by the second pulse output circuit 450 when receiving the fourth trigger signal.

The first voltage-dividing resistor may be much smaller than the second voltage-dividing resistor, for example, the second voltage-dividing resistor is 300k Ω (kilo ohms), the first voltage-dividing resistor is 5 Ω, and the like, but is not limited thereto. The driving voltage of the pulse output circuit is divided by the second voltage dividing resistor which is far larger than the first voltage dividing resistor, so that the first voltage dividing voltage and the second voltage dividing voltage obtained by voltage division are both small values and are easier to compare. It can be understood that the first voltage-dividing resistor and the second voltage-dividing resistor can be set according to actual requirements, and the specific resistance values of the first voltage-dividing resistor and the second voltage-dividing resistor are not limited in this embodiment of the application.

In the embodiment of the application, the condition of the load can be timely and accurately obtained by comparing the divided voltage of the reflux voltage with the reference voltage obtained by dividing the driving voltage, so that the conduction state of the pulse output circuit can be timely and accurately detected.

In one embodiment, the massage device 40 may further include a power-on circuit 470, and the power-on circuit 470 may be electrically connected to the control circuit 410 for sending a power-on command to the control circuit 410 when a power-on operation for the massage device is detected. For example, the startup circuit 470 may include a power-on key, and when the power-on key is pressed, the startup circuit sends a power-on command to the control circuit 410.

The control circuit 410 may receive the power-on instruction sent by the start circuit 470 before acquiring the number of effective pulse signals respectively output by each pulse output circuit sent by the wear detection circuit 430 in the third duration; and adjusting the driving voltage input to each pulse output circuit to a first voltage according to the starting command so that each pulse output circuit respectively outputs pulse signals under the driving of the driving voltage, so that the conduction state of a loop formed by each pulse output circuit and a human body through an electrode plate can be detected through the output pulse signals.

In one embodiment, when the electrode plate is normally attached to the human body, the electrode plate forms a passage with the human body, and the load of the massage device approaches the resistance of the human body, so that the number of stable pulse signals output by the pulse output circuit is larger. And if the number of the effective pulse signals output by a certain pulse output circuit in the third time length is larger than or equal to the first threshold value, determining that the pulse output circuit is in a normal conduction state. For example, when the third time duration is 500ms and the output frequency of the pulse signal is 50hz, and 25 pulse signals are output within 500ms, the first threshold may be a value less than 25, for example, 15 times, 10 times, 12 times, 9 times, and the like may be set, and the specific value may be set according to an empirical value.

Therefore, the control circuit 410, after acquiring the number of valid pulse signals respectively output by each pulse output circuit sent by the wear detection circuit 430 in the third time period, may be configured to determine the on state of the output pulse circuit that outputs the number of valid pulse signals equal to or greater than the first threshold as the normal on state.

In one embodiment, the abnormal conduction state includes a first abnormal conduction state, and the first abnormal conduction state may correspond to a conduction state of the pulse output circuit when the electrode sheet is poorly attached to the human body. When the electrode plate is not well attached to the human body, a less stable passage is formed between the electrode plate and the human body, and the contact area between the electrode plate and the human body is relatively small, so that the load resistance value of the massage equipment is increased, and the number of stable pulses output by the pulse output circuit is reduced. If the number of the effective pulse signals output by a certain pulse output circuit in the third time length is less than the first threshold value and greater than or equal to the second threshold value, the pulse output circuit can be determined to be in the first abnormal conduction state. The second threshold value may also be determined according to actual experiments, for example, 4 times, 2 times, and the like.

Therefore, after acquiring the number of valid pulse signals respectively output by each pulse output circuit sent by the wear detection circuit 430 in the third time period, the control circuit 410 may be configured to determine the conduction state of the pulse output circuit whose output number of valid pulse signals is less than the first threshold and greater than or equal to the second threshold as the first abnormal conduction state;

in one embodiment, the abnormal conduction state may further include a second abnormal conduction state, and the second abnormal conduction state may correspond to a conduction state of the pulse output circuit when the electrode sheet is not attached to the human body. When the electrode plate is not attached to the human body, the load resistance of the massage device approaches infinity, so that the number of stable pulse signals output by the pulse output circuit is extremely small or even 0. And if the number of the effective pulse signals output by a certain pulse output circuit in the third time length is less than the second threshold value, determining that the pulse output circuit is in a second abnormal conduction state.

Therefore, the control circuit 410, after acquiring the number of valid pulse signals respectively output by each pulse output circuit sent by the wear detection circuit 430 in the third time period, may be configured to determine the conduction state of the pulse output circuit, of which the number of output valid pulse signals is smaller than the second threshold, as the second abnormal conduction state.

In one embodiment, the massage device 40 may further include an output module 480, and the output module 480 may be electrically connected to the control circuit 410. The control circuit 410, after detecting the conducting state of each pulse output circuit, may further be configured to determine the wearing state of the massage apparatus according to the conducting state of each pulse output circuit, and send the wearing state of the massage apparatus to the output module 480. The output module 480 may be configured to output a wearing state of the massage device, so as to prompt a user, so that the user may adjust a wearing position of the massage device when the massage device is in an abnormal wearing state.

The wearing state of the massage apparatus may include a normal wearing state and an abnormal wearing state. The normal wearing state can be understood as that a plurality of electrode plates included in the massage equipment are normally attached to a human body; the abnormal wearing state can be understood as that electrode plates are abnormally attached to a human body in a plurality of electrode plates included in the massage equipment. Optionally, the abnormal wearing state can be further divided into: an unworn state and a wearing failure state. The non-wearing state can mean that a plurality of electrode plates included by the massage equipment are all attached to the human body abnormally; the wearing bad state can mean that one part of electrode plates included in the massage equipment is normally attached to a human body, and the other part of electrode plates is abnormally attached to the human body.

As an alternative embodiment, the control circuit 410 may be configured to determine that the massage apparatus is in a normal wearing state when detecting that each pulse output circuit is in a normal conducting state; or when detecting that each pulse output circuit included in the massage equipment is in an abnormal conduction state, determining that the massage equipment is in an unworn state; or when the first pulse output circuit is detected to be in an abnormal conduction state and the second pulse output circuit is detected to be in a normal conduction state, the massage equipment is determined to be in a poor wearing state.

The output module 480 may include a vibration module, and may output a wearing state of the massage apparatus through vibration of the vibration module. For example, when the wearing state of the massage equipment is a normal wearing state, an unworn state and a poor wearing state, the vibration module can output different vibration times so as to represent different wearing states through different vibration times.

Alternatively, the output module 480 may include a speaker to output the wearing state of the massage apparatus by voice using the speaker. For example, the speaker may output voice prompt information such as "poor wearing of the massage apparatus" to prompt the user of the wearing state of the massage apparatus.

Alternatively, the output module 480 may include a display module to display the wearing state of the massage device by using the display module. For example, when the wearing state of the massage device is a normal wearing state, an unworn state and a bad wearing state, the display module can output light with different colors, such as green light when the massage device is in the normal wearing state and red light when the massage device is in the abnormal wearing state, so as to prompt the wearing state of the massage device of the user through the light with different colors.

Alternatively, the output module 480 may output the wearing state of the massage apparatus to the communication module of the massage apparatus. The massage equipment can be in communication connection with mobile terminals such as smart phones through the communication module. The communication module of the massage device can send the received output instruction to the mobile terminal through the communication connection. After receiving the output instruction, the mobile terminal can read the wearing state of the massage equipment from the output instruction and output the wearing state in one or more prompting modes such as voice, characters and pop windows, so that a user can learn the wearing state of the massage equipment through the mobile terminal.
