For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] The structure of the massage device provided by the present application is briefly described below through multiple embodiments.

[0051] Figure 1 A schematic diagram of the structure of a massage device provided in an embodiment of the present application; Figure 1 As shown, the massage device 100 includes: a control module 101, a driving module 102 and at least one group of massage ball head components, and each group of massage ball head components includes: a heating control unit 103 and at least one massage ball head.

[0052] The massage device 100 provided in this embodiment may be a massage chair or other massage equipment.

[0053] Exemplarily, for example, the control module 101 can be the main controller in the massage chair. The user can turn on the massage heating function or the massage function through the main controller of the massage chair. After receiving this instruction, the main controller in the massage chair sends a massage ball heating start instruction to the drive module 102 through the communication port on the main controller.

[0054] In another possible implementation, for example, the user can activate the massage heating function through a shortcut button on the massage chair or voice control.

[0055] Exemplarily, for example, the driving module 102 may be a driving board in a massage chair.

[0056] Continue to refer Figure 1 As shown, the output end of the control module 101 is connected to the input end of the driving module 102, and the control module 101 is used to send a heating start signal to the driving module 102 after receiving a massage heating control instruction.

[0057] The output end of the driving module 102 is connected to the input end of the heating control unit 103 in each group of massage ball head assemblies, and the driving module 102 is used to transmit a heating start signal to the heating control unit 103 .

[0058] In this embodiment, for example, after receiving the massage heating control instruction, the driving module 102 sends a heating start signal to the heating control unit 103 in each group of massage ball head assemblies through the communication port on the driving module 102. The heating control unit 103 in each group of massage ball head assemblies heats each massage head under the action of the heating start signal.

[0059] refer to Figure 1 As shown, taking a group of massage ball head assemblies in a massage chair as an example, the output end of the heating control unit 103 in the group of massage ball head assemblies can be connected to one end of the coils in multiple massage ball heads, and the heating control unit 103 is used to output a high-frequency AC signal to the coils in each massage ball head under the action of a heating signal, so as to heat the components to be heated in each massage ball head through the high-frequency magnetic field generated by the high-frequency AC signal.

[0060] In one achievable manner, for example, the output end of the heating control unit 103 can be connected to the coils in two massage ball heads, that is, two massage ball heads in the massage device can be heated by one heating control unit 103. Specifically, when the heating signal is turned on, the heating control unit 103 provides a high-frequency AC signal to the coils in each massage ball head, so that the coils generate a relatively high-frequency magnetic field, and the eddy current thermal effect generated by the high-frequency electromagnetic field heats the components to be heated in the massage ball head. That is, this solution uses the heating control unit to convert the existing DC power supply into AC power supply, so that a more efficient heating method can be provided through the coils in each massage ball head, thereby realizing rapid heating of the surface of each massage ball head.

[0061] It should be understood that its principle is based on Faraday's law of electromagnetic induction and Joule heating effect. When a high-frequency current passes through a conductor, an alternating electromagnetic field is generated inside the conductor. This alternating electromagnetic field will cause a current inside the conductor, which is called eddy current, and is also the key to high-frequency magnetic field heating. The formation of eddy current will cause the resistor inside the massage ball head to heat up, which is the Joule heating effect. When the frequency of the high-frequency magnetic field is moderate, the eddy current will be concentrated near the surface of the conductor, causing the conductor near the surface to heat up, while the internal heat conduction is relatively small.

[0062] It should be noted that the current solution of AC power supply generally requires additional transformers or customized switching power boards to increase AC output, which greatly increases costs and cannot achieve higher frequency output, thus failing to achieve the expected heating effect. The heating control unit provided by this solution can achieve high-frequency AC output without adding additional transformers or using a general switching power board, greatly shortening the heating time and improving the expected heating effect. Therefore, the heating control unit provided by this solution does not need to change the traditional switching power board, and can directly use DC power to ensure a safe heating method.

[0063] In summary, the embodiment of the present application provides a massage device. In this solution, the heating control unit outputs a high-frequency AC signal to the coil in each massage ball head under the action of the heating start signal issued by the control module and the drive module, thereby causing the coil to generate a relatively high-frequency magnetic field. The eddy current thermal effect generated by the high-frequency electromagnetic field heats the components to be heated in the massage ball head. Therefore, the heating control unit in this solution can be used to convert the existing DC power supply into AC power supply, so that a more efficient heating method can be provided through the coil in each massage ball head, realizing rapid heating of the surface of each massage ball head, and effectively solving the problems of low heating efficiency and slow heat conduction speed in the PCT heating method in the prior art.

[0064] The above-mentioned Figure 1 The structure of the heating control unit is introduced in detail.

[0065] Optionally, refer to Figure 2 As shown above Figure 1 The heating control unit 103 includes: a control subunit 201 and a heating circuit 202.

[0066] Exemplarily, for example, the control subunit 201 may be a processing device having a data processing function, such as a microcontroller unit (MCU) or a single-chip microcomputer.

[0067] Continue to refer Figure 2As shown, the input end of the control subunit 201 is connected to the output end of the driving module 102, and the control subunit 201 is used to output a heating signal to the heating circuit 202 after receiving the heating start signal. Exemplarily, for example, the heating signal can be a high or low level signal. For example, 1 is a heating signal, and 0 is a stop heating signal.

[0068] The output end of the control subunit 201 is connected to the input end of the heating circuit 202, and the output end of the heating circuit 202 is connected to one end of the coil in each massage ball head; the heating circuit 202 is used to output a high-frequency AC signal to the coil in each massage ball head under the action of the heating signal.

[0069] In this embodiment, for example, the heating circuit 202 outputs a high-frequency AC signal to the coils in each massage ball head under the action of the start heating signal, that is, the action of the heating signal 1. For another example, the heating circuit 202 stops outputting the high-frequency AC signal to the coils in each massage ball head under the action of the stop heating signal, that is, the action of the stop heating signal 0, thereby realizing the closing function of the heating circuit.

[0070] Optionally, continue to refer to Figure 3 As shown above Figure 1 The heating control unit further comprises: a temperature sensing unit 8; the temperature sensing unit 8 is arranged inside the massage ball head, that is, the temperature sensing unit 8 is arranged inside each massage ball head.

[0071] One end of the temperature sensing unit 8 is connected to the input end of the control subunit 201 . The temperature sensing unit 8 is used to detect the temperature inside the massage ball head and send the temperature to the control subunit 201 .

[0072] The control subunit 201 is also used to send a heating stop signal to the heating circuit when it is detected that the current temperature of the massage ball head reaches the set temperature.

[0073] For example, the set temperature is 37°C. During the operation of the massage device, if the control subunit 201 detects that the current temperature of the massage ball head collected by the temperature sensing unit 8 is 37°C and reaches the set temperature, the control subunit 201 sends a stop heating signal to the heating circuit 202 to avoid excessive heating temperature that may cause skin burns to the user, thereby ensuring safety during the use of the massage device.

[0074] Optionally, the heating circuit 202 is also used to stop outputting high-frequency AC signals to the coils in each massage ball head under the action of a stop heating signal.

[0075] In this embodiment, the heating circuit 202 stops outputting the high-frequency AC signal under the action of the stop heating signal, that is, the shutdown function of the heating circuit is realized.

[0076] Optionally, the above Figure 3 The temperature sensing unit includes at least a negative temperature coefficient thermistor.

[0077] In this embodiment, a negative temperature coefficient (NTC) temperature sensor is used as a temperature sensing unit, wherein the resistance value of the NTC thermistor in the NTC temperature sensor decreases as the temperature increases. Therefore, the current temperature of the massage head can be detected by measuring the change in the resistance value of the NTC thermistor, thereby improving the accuracy of the detection.

[0078] Optionally, refer to Figure 4 As shown above Figure 2 The heating circuit in at least includes: a heating chip 401 and a first resistor R1.

[0079] Wherein, the first pin of the heating chip 401 is connected to the first output port of the control subunit 201;

[0080] The second pin of the heating chip 401 is connected to the second output port of the control subunit 201;

[0081] The third pin of the heating chip 401 is connected to the third output port of the control subunit 201;

[0082] The fourth pin of the heating chip 401 is connected to the fourth output port of the control subunit 201;

[0083] The fifth pin of the heating chip 401 is connected to the fifth output port of the control subunit 201;

[0084] The sixth pin of the heating chip 401 is connected to one end of the first resistor R1 , and the other end of the first resistor R1 is grounded.

[0085] In this embodiment, the first pin of the heating chip 401 is the Reset pin, that is, the reset pin 16 in the heating chip 401. The control subunit 201 outputs a low level reset drive to the heating chip 401 through the MCU_Reset pin. Under normal circumstances, a high level enables this chip.

[0086] The second pin of the heating chip 401 is the Enable pin, that is, the 21st PWM input pin in the heating chip 401. The control subunit 201 adjusts the duty cycle of the PWM through MCU_Enbl to adjust the level of the output voltage.

[0087] The third pin of the heating chip 401 is the Phase pin, that is, the switching pin No. 20 in the heating chip 401. The control subunit 201 adjusts the positive and negative directions of the voltages of the output pins OUT1 and OUT2 of the heating chip 401 by changing the high and low levels of MCU_Phase.

[0088] The fourth pin of the heating chip 401 is the Decay pin, that is, the brake pin No. 19 in the heating chip 401. The control subunit 201 controls the output pause mode through the MCU_Decay pin. When the high level is high, it is fast shut down, and when the low level is low, it is slow shut down.

[0089] The fifth pin of the heating chip 401 is the Fault pin, that is, the error output pin No. 18 in the heating chip 401. When the heating chip 401 is overheated or overcurrent occurs, a low level is output to the MCU_Fault pin through this pin. After the control subunit 201 receives this signal, it resets the driving chip through the Reset pin, thereby protecting the chip from damage.

[0090] The sixth pin of the heating chip 401 is the ISEN pin, ie, pin No. 9 of the heating chip 401 .

[0091] (1) In heating mode, the specific working principle is as follows:

[0092] After the control subunit 201 receives the instruction to start heating, it configures the MCU_Reset pin of the five ports to output a high level, the MCU_Enble pin to output a high level, the MCU_Decay pin to output a high level, the MCU_Fault pin to be configured as an internal pull-up input pin, and the MCU_Phase pin to output a 50KHz equal-pulse-width level signal. At this time, the output pins OUT1 and OUT2 of the heating chip 401 will output a high-frequency AC changing signal with an equal pulse width at a level changing frequency of 50KHz, providing a high-frequency AC level to the coil in each massage ball head, so that the coil generates a high-frequency changing magnetic field, and the eddy current thermal effect generated by the high-frequency electromagnetic field heats the components to be heated in each massage ball head, thereby achieving rapid heating of the surface of each massage ball head.

[0093] (2) When the heating mode is stopped, the specific working principle is as follows:

[0094] After the control subunit 201 receives the instruction to stop heating, it configures the MCU_Reset pin of the five ports to output a low level, the MCU_Enbl pin to output a low level, the MCU_Decay pin to output a high level, the MCU_Fault pin to be configured as an internal pull-up input pin, and the MCU_Phase pin to shut down the signal output. At this time, the output pins OUT1 and OUT2 of the heating chip 401 no longer have signal outputs, thereby realizing the shutdown function of the heating circuit.

[0095] In one feasible manner, for example, after the user turns on the massage heating, when the temperature sensing unit is damaged, if the current temperature of the massage ball head changes too quickly, changes too slowly, or stops changing, and the control subunit detects that the change rate is significantly different from the set rate, the control subunit automatically shuts down the output of the control heating circuit through the configuration of 5 ports.

[0096] Optionally, continue to refer to Figure 4 As shown, the first resistor R1 is a chip fuse.

[0097] In this embodiment, for example, after the user turns on the massage heating, the coil in the massage ball head is short-circuited to generate a large current, and the heating chip is damaged. The heating chip cannot provide a high-frequency AC signal to the coil in the massage ball head. When it is converted into a DC current, the first resistor R1 can be replaced with a chip fuse of the same resistance value. When the current reaches the fuse melting current, the fuse melts, thereby cutting off the power supply circuit of the coil, disconnecting the power supply of the coil, and stopping heating. This improves the safety factor of the heating system of the entire massage device, ensuring that the massage head will not be overheated, causing overheating and fire or scalding the user.

[0098] Optionally, the heating control unit further includes: a temperature switch.

[0099] The first output pin OUT1 of the heating chip is connected to one end of the temperature switch, the other end of the temperature switch is connected to one end of the coil, and the other end of the coil is connected to the second output pin OUT2 of the heating chip.

[0100] In this embodiment, the temperature switch is built into the heating head, and the first output pin OUT1 of the heating chip 401, the temperature switch, the coil, and the second output pin OUT2 of the heating chip are connected in series. After the user turns on the massage heating, when the heating chip is damaged and is not controlled by the control subunit, when the temperature of the massage ball head rises to the warning temperature, the temperature switch is disconnected, thereby disconnecting the power supply circuit of the coil, disconnecting the power supply of the coil, and stopping the heating.

[0101] Optionally, each massage ball head is further provided with a magnetic blocking sheet, which is arranged between a fixed bracket and the coil inside the massage ball head.

[0102] In this embodiment, reference Figure 5 As shown, a schematic diagram of the massage head assembly provided in the embodiment of the present application being installed on the massage machine core. Figure 5 The massage movement shown in the figure includes: a massage head assembly 1, a driving mechanism 2, a running device 3 and a frame 4.

[0103] Among them, the massage head assembly 1 is a component that contacts the human body to perform massage actions on the human body; the driving mechanism 2 is a device that makes the massage head assembly 1 move to produce massage actions; the walking device 3 is a device that drives the entire massage movement to move to change the massage position; the frame 4 is a component that provides fixation or support for the above components.

[0104] In this embodiment, reference Figure 6 As shown, in order to heat the component 5 to be heated faster, a magnetic blocking sheet ( Figure 6 ), to prevent the magnetic field from heating the fixed support.

[0105] Optionally, the above Figure 1 The heating control unit is arranged in Figure 5 On the massage movement in the massage device shown.

[0106] Figure 6 It is a structural exploded diagram of the massage head assembly; Figure 7 It is a structural cross-sectional view of each massage head assembly in the massage device.

[0107] from Figure 5-Figure 7 It can be seen that the massage ball head is located on the massage arm, the massage arm is installed on the massage movement, and the massage movement is installed on the massage chair or massage equipment. This heating control unit can be installed on the movement to improve the flexibility of the installation of the heating control unit.

[0108] also, Figure 6 and Figure 7 The massage ball head also includes a temperature sensing unit 8, that is, the temperature inside the massage ball head can be collected through the temperature sensing unit 8.
