Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to an electrical pulse output circuit and a massage device. Background Technology

[0002] With the rapid development of electronic technology in the healthcare field, more and more massage devices based on electrical pulses have appeared on the market. When using the above-mentioned massage devices, users attach one or more electrical pulse output patches on the massage device to the area where they need to be massaged. This allows the massage device to output electrical pulse signals to the area where the user needs to be massaged through the electrical pulse output patches, so that the electrical pulse signals can be directly applied to the user's skin and transmitted to the muscle tissue to achieve a massage effect.

[0003] Currently, most massage devices include a microcontroller, a dry cell battery, and a pulse output circuit connected to an electrical pulse output patch. The pulse output circuit obtains voltage from the dry cell battery and transmits it to the electrical pulse output patch to massage the user. The pulse output circuit contains a switching device; when the switching device is on, the voltage output from the dry cell battery can be transmitted to the electrical pulse output patch; when the switching device is off, the voltage output from the dry cell battery cannot be transmitted to the electrical pulse output patch. Furthermore, the microcontroller controls the switching device to periodically turn on and off, so that the voltage provided by the dry cell battery is output as an electrical pulse signal through the electrical pulse output patch, thereby achieving the massage effect on the user.

[0004] However, existing dry cell batteries can only provide a relatively low voltage, which is insufficient to effectively stimulate the user's muscle tissue, resulting in a low electro-pulse massage effect in existing massage devices. Utility Model Content

[0032] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0033] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0034] The following is combined Figures 1 to 10This invention describes an electrical pulse output circuit and a massage device according to some embodiments of the present invention.

[0035] like Figure 1 As shown in the figure, one embodiment of this utility model discloses an electrical pulse output circuit, which includes a voltage input circuit 100, a high voltage generation circuit 200, and multiple massage electrode circuits 300. Each massage electrode circuit 300 includes a switching circuit (not shown) and an electrical pulse output patch 310. When massage is needed, the electrical pulse output patch 310 on the massage electrode circuit 300 can be placed on the area of ​​the user's body that requires massage.

[0036] Specifically, the power input terminal of the voltage access circuit 100 is connected to the power output terminal of the external voltage source E to obtain the power voltage from the external voltage source E, wherein the external voltage source E can be a battery.

[0037] Furthermore, the power output terminal of the voltage access circuit 100 is connected to the voltage access terminal of the high voltage generating circuit 200. The voltage access circuit 100 is controlled to be in a conducting or disconnected state. When the voltage access circuit 100 is in a conducting state, the high voltage generating circuit 200 can obtain the power supply voltage from the external voltage source E through the voltage access circuit 100. Conversely, when the voltage access circuit 100 is in a disconnected state, the high voltage generating circuit 200 cannot obtain the power supply voltage from the external voltage source E through the voltage access circuit 100.

[0038] Furthermore, the power output terminal of the high-voltage generating circuit 200 is connected to the power input terminal of each of the massage electrode circuits 300. The high-voltage generating circuit 200 is used to boost the power supply voltage to obtain a boosted voltage, and then sends the boosted voltage to each of the massage electrode circuits 300. The high-voltage generating circuit 200 may include a boost converter, which is a switching mode power supply that uses components such as inductors, diodes, and capacitors in conjunction with the operation of switches (such as MOSFETs or transistors) to increase the input DC voltage to the required output voltage. Specifically, the high-voltage generating circuit 200 can introduce the power supply voltage to the input terminal of the boost converter, and the boosted voltage after boosting is output from the output terminal of the boost converter to the massage electrode circuit 300.

[0039] Furthermore, the switching circuit of the massage electrode circuit 300 is periodically in a conducting state or a disconnected state. When the switching circuit is in a conducting state, the massage electrode circuit 300 outputs the boosted voltage through the electrical pulse output patch 310. When the switching circuit is in a disconnected state, the massage electrode circuit 300 stops outputting the boosted voltage through the electrical pulse output patch 310.

[0040] Here, the switching circuit in the massage electrode circuit 300 can be a transistor. The source terminal of the transistor is connected to the power output terminal of the high voltage generation circuit 200, and the drain terminal of the transistor is connected to the electrical pulse output patch 310. The gate terminal of the transistor can be connected to an external pulse width modulation (PWM) signal source. The PWM signal source can send a pulse width modulation signal with a specific duty cycle to the gate terminal of the transistor. When the gate terminal of the transistor receives a high-level signal, the transistor is turned on, enabling the massage electrode circuit 300 to output a boost voltage through the electrical pulse output patch 310. When the gate terminal of the transistor receives a low-level signal, the transistor is turned off, causing the massage electrode circuit 300 to stop outputting a boost voltage through the electrical pulse output patch 310, so that the massage electrode circuit 300 can output a voltage signal in the form of an electrical pulse signal through the electrical pulse output patch 310.

[0041] The electrical pulse output circuit proposed in this embodiment of the invention can receive power from an external voltage source, such as a dry cell battery, through a voltage access circuit. The power supply voltage is then boosted by a high-voltage generation circuit to obtain a boosted voltage. Furthermore, when massage is required, the electrical pulse output patch on the massage electrode circuit can be placed on the area of ​​the user's body that needs massage. The massage electrode circuit obtains a higher boosted voltage value and, through the switching circuit, intermittently outputs the boosted voltage to the area requiring massage, effectively stimulating the muscle tissue and thus improving the massage effect.

[0042] In one embodiment, such as Figure 2 As shown, the massage electrode circuit includes a first output circuit 330 and a second output circuit 340; the switch circuit includes a first switch circuit 350 and a second switch circuit 360; the electrical pulse output patch includes a first output terminal OUT1 disposed at the first output circuit 330 and a second output terminal OUT2 disposed at the second output circuit 340.

[0043] Furthermore, the power input terminal of the first output circuit 330 is connected to the power output terminal of the high voltage generating circuit 200 to obtain the boost voltage. The first control terminal of the first output circuit 330 is connected to the first terminal of the first switching circuit 350, and the second terminal of the first switching circuit 350 is grounded. The second control terminal of the first output circuit 330 is connected to the first terminal of the second switching circuit 360, and the second terminal of the second switching circuit 360 is grounded.

[0044] Specifically, when the first switching circuit 350 is turned on and the second switching circuit 360 is turned off, the first output terminal OUT1 of the first output circuit 330 outputs the boosted voltage.

[0045] Furthermore, the power input terminal of the second output circuit 340 is connected to the power output terminal of the high voltage generating circuit 200 to obtain the boost voltage. The first control terminal of the second output circuit 340 is connected to the first terminal of the second switching circuit 360, and the second control terminal of the second output circuit 340 is connected to the first terminal of the first switching circuit 350.

[0046] Specifically, when the first switching circuit 350 is open and the second switching circuit 360 is open, the second output terminal OUT2 of the second output circuit 340 outputs the boosted voltage.

[0047] The embodiments provided in this application can precisely control the output voltage of the massage electrode circuit in the form of pulse signals by controlling the on / off state of the first and second switching circuits, thus providing a hardware basis for precisely outputting voltage through the massage electrode circuit to stimulate the user's muscle tissue.

[0048] In one embodiment, such as Figure 3 As shown, the electrical pulse output circuit also includes a control unit (MCU). The MCU is connected to the voltage input circuit 100, the high voltage generation circuit 200, and each massage electrode circuit 300 to control these components. The MCU can be a microcontroller, digital signal processor, or other computer device.

[0049] Furthermore, such as Figure 4As shown, in each massage electrode circuit, the first control terminal of the control unit MCU is connected to the control terminal of the first switch circuit 350 in the massage electrode circuit, and the second control terminal of the control unit MCU is connected to the control terminal of the second switch circuit 360 in the massage electrode circuit. Here, the control unit MCU is used to keep the first switch circuit 350 and the second switch circuit 360 in a conducting or disconnected state. The control unit MCU can be pre-set with a control program from the prior art to control the first output terminal OUT1 to output a specific electrical pulse waveform signal. Specifically, when the signal pulse peak of the electrical pulse waveform signal needs to be output, the control unit MCU controls the first and second terminals of the first switch circuit 350 to conduct, and controls the first and second terminals of the second switch circuit 360 to disconnect, thereby causing the first output terminal OUT1 to output a boost voltage. When the electrical pulse waveform signal is at the interval between adjacent signal pulse peaks, the first and second terminals of the first switch circuit 350 are disconnected, and the first and second terminals of the second switch circuit 360 are conducted, thereby preventing the first output terminal OUT1 from outputting a boost voltage, thus achieving the effect of outputting a specific electrical pulse waveform signal through the first output terminal OUT1. Furthermore, the method of outputting the electrical pulse waveform signal via the second output terminal OUT2 can refer to the method of outputting the electrical pulse waveform signal via the first output terminal OUT1 described above, and will not be repeated here. The embodiments provided in this application include a control unit in the electrical pulse output circuit, and a computer program from the prior art can be pre-configured in the control unit to precisely control the voltage output of each massage electrode circuit, thereby improving the control accuracy of the electrical pulse output circuit and thus enhancing the massage effect on the user.

[0050] In one embodiment, such as Figure 5 As shown, the first output circuit includes a first transistor S1, a second transistor S2, a first resistor R1, a second resistor R2, and a third resistor R3; the first switching circuit includes a fourth resistor R4 and a third transistor S3; and the second switching circuit includes a fifth resistor R5 and a fourth transistor S4.

[0051] Specifically, the emitter of the first transistor S1 and the first end of the first resistor R1 are connected to the power output terminal of the high voltage generating circuit 200, the collector of the first transistor S1 is connected to the emitter of the second transistor S2 and the first output terminal OUT1, and the collector of the second transistor S2 is grounded.

[0052] Furthermore, the first control terminal of the control unit MCU is connected to the first terminal of the fourth resistor R4, the second terminal of the fourth resistor R4 is connected to the base terminal of the third transistor S3, the emitter terminal of the third transistor S3 is grounded, the collector terminal of the third transistor S3 is connected to the first terminal of the second resistor R2, and the second terminal of the second resistor R2 is connected to the base terminal of the first transistor S1 and the second terminal of the first resistor R1, respectively.

[0053] Furthermore, the first end of the third resistor R3 is connected to the base of the second transistor S2, the second end of the third resistor R3 is connected to the collector of the fourth transistor S4, the emitter of the fourth transistor S4 is grounded, the base of the fourth transistor S4 is connected to the first end of the fifth resistor R5, and the second end of the fifth resistor R5 is connected to the second control terminal of the control unit MCU. Here, when the control unit MCU sends a high-level signal to the first end of the fourth resistor R4, the third transistor S3 conducts, allowing the voltage output by the high-voltage generating circuit 200 to act on the base of the first transistor S1, thereby turning on the first transistor S1. Simultaneously, when the control unit MCU sends a low-level signal to the second end of the fifth resistor R5, the fourth transistor S4 is turned off, preventing the base of the second transistor S2 from receiving voltage, thus turning off the second transistor S2. At this time, the boosted voltage output by the high-voltage generating circuit 200 can be output to the user's skin through the first output terminal OUT1. Conversely, when the control unit MCU sends a low-level signal to the first terminal of the fourth resistor R4 and a high-level signal to the second terminal of the fifth resistor R5, the circuit connection between the first output terminal OUT1 and the high-voltage generating circuit 200 can be disconnected, thereby preventing the voltage output by the high-voltage generating circuit 200 from being output to the user's skin through the first output terminal OUT1.

[0054] Furthermore, the second output circuit includes a fifth transistor S5, a sixth transistor S6, a sixth resistor R6, a seventh resistor R7, and an eighth resistor R8.

[0055] Specifically, the emitter of the fifth transistor S5 and the first end of the sixth resistor R6 are connected to the power output terminal of the high voltage generating circuit 200. The collector of the fifth transistor S5 is connected to the second output terminal OUT2 and the emitter of the sixth transistor S6, respectively. The collector of the sixth transistor S6 is grounded.

[0056] Furthermore, the second end of the sixth resistor R6 is connected to the base terminal of the fifth transistor S5 and the first end of the seventh resistor R7, and the second end of the seventh resistor R7 is connected to the collector terminal of the fourth transistor S4.

[0057] Furthermore, the base of the sixth transistor S6 is connected to the first terminal of the eighth resistor R8, and the second terminal of the eighth resistor R8 is connected to the collector of the third transistor S3. Here, when the control unit MCU sends a high-level signal to the second terminal of the fifth resistor R5, the fourth transistor S4 turns on, allowing the voltage output by the high-voltage generating circuit 200 to act on the base of the fifth transistor S5, thereby turning on the fifth transistor S5. Simultaneously, when the control unit MCU sends a low-level signal to the first terminal of the fourth resistor R4, the third transistor S3 turns off, preventing the base of the sixth transistor S6 from receiving voltage, thus turning off the sixth transistor S6. At this time, the boosted voltage output by the high-voltage generating circuit 200 can be output to the user's skin via the second output terminal OUT2. Conversely, when the control unit MCU sends a high-level signal to the first end of the fourth resistor R4 and a low-level signal to the second end of the fifth resistor R5, the circuit connection between the second output terminal OUT2 and the high-voltage generating circuit 200 can be disconnected, thereby preventing the voltage output by the high-voltage generating circuit 200 from being output to the user's skin through the second output terminal OUT2.

[0058] The embodiments provided in this application enable the control unit to precisely control the output of high-voltage or low-voltage signals of the massage electrode circuit by sending electrical signals to the first and second switching circuits of each massage electrode circuit, so as to accurately output electrical pulse waveform signals to the user's skin, thereby achieving massage for the user and improving the massage effect.

[0059] In one embodiment, such as Figure 6 As shown, the high-voltage generating circuit includes a first capacitor C1, a second capacitor C2, a third capacitor C3, a ninth resistor R9, a tenth resistor R10, an eleventh resistor R11, a first inductor L1, a first Schottky diode D1, a seventh transistor S7, and an eighth transistor S8.

[0060] Specifically, the first terminal of the first capacitor C1, the first terminal of the second capacitor C2, and the first terminal of the first inductor L1 are connected to the power output terminal of the voltage access circuit 100, and the second terminals of the first capacitor C1 and the second terminal of the second capacitor C2 are grounded. Here, the voltage access circuit 100 can output the power supply voltage to the high-voltage generation circuit.

[0061] Furthermore, the second terminal of the first inductor L1 is connected to the anode of the first Schottky diode D1 and the collector of the seventh transistor S7, respectively. The emitter of the seventh transistor S7 is grounded, the base of the seventh transistor S7 is connected to the first terminal of the ninth resistor R9, and the second terminal of the ninth resistor R9 is connected to the third control terminal of the control unit MCU.

[0062] Furthermore, the cathode of the first Schottky diode D1 is connected to the first terminal of the third capacitor C3, the power input terminal of the massage electrode circuit 300, and the first terminal of the tenth resistor R10, respectively. The second terminal of the third capacitor C3 is grounded. The second terminal of the tenth resistor R10 is connected to the collector terminal of the eighth transistor S8. The emitter terminal of the eighth transistor S8 is grounded. The base terminal of the eighth transistor S8 is connected to the first terminal of the eleventh resistor R11. The second terminal of the eleventh resistor R11 is connected to the fourth control terminal of the control unit MCU.

[0063] Here, the high-voltage generating circuit can form a boost chopper circuit. When the control unit MCU turns on the seventh transistor S7, the input voltage flows through the first inductor L1. Since the voltage input circuit 100 is DC, the current in the first inductor L1 increases linearly at a certain rate, which is related to the size of the first inductor L1. As the inductor current increases, some energy is stored in the first inductor L1. Subsequently, when the control unit MCU turns off the seventh transistor S7, due to the current holding characteristic of the first inductor L1, the current flowing through the first inductor L1 does not immediately become 0, but slowly changes from its value when fully charged to 0. At the same time, it charges the third capacitor C3, causing the voltage across the third capacitor C3 to rise. At this point, the voltage is higher than the input voltage, and the voltage boost is complete. Furthermore, the boosted voltage can be output to the massage electrode circuit 300 to realize the function of the massage electrode circuit 300.

[0064] The embodiments provided in this application can boost the voltage output from an external voltage source based on a high-voltage generation circuit, ensuring that the electrical pulse waveform signal applied to the user's skin via the massage electrode circuit has a sufficient voltage value to guarantee the massage effect on the user.

[0065] In one embodiment, such as Figure 7 As shown, the control unit MCU has a first control sub-terminal and a second control sub-terminal. The voltage access circuit includes a first switching transistor Q1, a ninth transistor S9, a second Schottky diode D2, a third Schottky diode D3, a fourth Schottky diode D4, a fourth capacitor C4, a twelfth resistor R12, a thirteenth resistor R13, a fourteenth resistor R14, and a fifteenth resistor R15.
