[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention. In the present invention, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0020] Please refer to Figures 1-4 The physiotherapy device 100 of this application includes a housing 1, a stimulation element 2, a power supply 3, a current adjustment component 4, and a circuit board 5. The stimulation element 2 is disposed on the housing 1. The power supply 3 is electrically connected to the stimulation element 2 to supply power to the stimulation element 2. The stimulation element 2 can convert electrical energy into physical energy to perform physiotherapy on the skin. The current adjustment component 4 includes a positioning part 41 and a pressure sensor 42. The positioning part 41 is disposed on the outer wall surface of the housing 1 for the user to press. The user can apply pressure to the positioning part 41 by pressing it. The pressure sensor 42 is disposed adjacent to the positioning part 41 to detect the magnitude of the pressure transmitted by the positioning part 41. The circuit board 5 is electrically connected to the power supply 3 and the pressure sensor 42 respectively. The circuit board 5 can control the magnitude of the current output by the power supply 3 to the stimulation element 2 according to the magnitude of the pressure, thereby adjusting the physiotherapy intensity of the stimulation element 2. On the one hand, by pressing the positioning part 41 on the housing 1, the user can change the current output from the power supply 3 to the stimulation element 2 in real time based on the pressure applied, thereby autonomously adjusting the physiotherapy intensity to meet the needs of different individuals, different body parts, and different tolerance levels. This improves upon the problem of the fixed current output of the existing physiotherapy device 100, which cannot be adjusted according to user needs. On the other hand, the housing 1 can be used as a handle for the physiotherapy device 100. When holding the housing 1 for skin care, the user can naturally press the positioning part 41 with their fingers without changing their grip or interrupting the physiotherapy process. This operation is convenient and ergonomic.

[0021] In this embodiment, the power supply unit 3 can be a nickel-metal hydride battery, a lithium-ion battery, or a lithium polymer battery. The power supply unit 3 is charged through a charging interface provided on the housing 1.

[0022] In this embodiment, the stimulation element 2 can be fixed to or onto the housing 1 by means of welding, adhesive, snap-fit ​​connection, screw connection, etc., and no limitation is made here. The stimulation element 2 may include at least one of the following: conductive component 21, phototherapy lamp 22, semiconductor cooling component, vibration motor, etc.

[0023] In this embodiment, the positioning portion 41 may be disposed on the outer wall surface of the housing 1 by means of adhesive, snap connection, integral molding, etc., so as to facilitate the user's touch and pressing. The positioning portion 41 may slightly protrude from the outer surface of the housing 1, or the positioning portion 41 may be slightly recessed relative to the outer surface of the housing 1, or the positioning portion 41 may be flush with the outer surface of the housing 1, which is not limited herein.

[0024] In one embodiment, a microcontroller (MCU), a battery management circuit, a boost drive circuit, and a signal processing circuit are integrated on the circuit board 5. The output end of the pressure sensor 42 is electrically connected to the signal input end of the circuit board 5, and the control output end of the circuit board 5 is electrically connected to the stimulation element 2 through the boost drive circuit. A pressure-current mapping program is built in the circuit board 5. After receiving the pressure signal detected by the pressure sensor 42, the MCU calculates the target current value according to the preset mapping relationship, and then controls the magnitude of the current output from the power supply member 3 to the stimulation element 2 by means of pulse width modulation or a constant current source.

[0025] For example, a segmented mapping program is built in the circuit board 5, the maximum current output from the power supply member 3 to the stimulation element 2 is I, the pressing force (F) range detected by the pressure sensor 42 is divided into a plurality of continuous but non-overlapping pressure intervals, and each interval corresponds to an output current gear: when the pressure satisfies 1.0N<F≤2.5N, the current output from the power supply member 3 to the stimulation element 2 is 10%-30% of I; when the pressure satisfies 2.5N<F≤4.0N, the current output from the power supply member 3 to the stimulation element 2 is 31%-70% of I; when the pressure satisfies 4.0N<F≤6.0N, the current output from the power supply member 3 to the stimulation element 2 is 71%-100% of I. For another example, a pressure-current linear mapping program is built in the circuit board 5. After receiving the pressure signal detected by the pressure sensor 42, the MCU calculates the target current value according to the preset linear mapping relationship, and then controls the magnitude of the current output from the power supply member 3 to the stimulation element 2 by means of pulse width modulation (PWM) or a constant current source.

[0026] In another embodiment, circuit board 5 includes a signal conditioning circuit and an analog power control circuit. The analog power control circuit includes a voltage-to-current conversion circuit, employing a resistive thin-film pressure sensor (FSR) and a fixed resistor to form a voltage divider circuit. When the pressure increases, the resistance of the FSR decreases, and the voltage at the voltage divider point V1 increases linearly. V1 is amplified by a non-inverting amplifier circuit composed of a single-supply operational amplifier to obtain V2 = V1*K, where K is the amplification factor. Then, V2 directly drives a voltage-controlled constant current source circuit composed of an operational amplifier and a metal-oxide-semiconductor field-effect transistor. The stimulation element 2 is connected in series between the drain of the metal-oxide-semiconductor field-effect transistor and the power supply element 3. When the user lightly presses the positioning part 41, V2 is low, and the constant current source outputs a small current; when the user presses the positioning part 41 harder, V2 increases, and the output current of the constant current source increases linearly.

[0027] In one specific embodiment, reference is made to Figure 2 and Figure 3 The stimulation element 2 is a phototherapy lamp 22, which is fixed in the housing 1. A light-transmitting plate 18 is provided on the housing 1, and the phototherapy lamp 22 is positioned facing the light-transmitting plate 18, allowing the light emitted by the lamp to be emitted outwards through the plate. The circuit board 5 controls the current output from the power supply 3 to the phototherapy lamp 22 according to the pressure, thereby adjusting the light intensity of the lamp. In this embodiment, the phototherapy lamp 22 can be a white light, red light, blue light, ultraviolet light, or infrared light, etc., and can be configured as needed. There can be one or more phototherapy lamps 22. When there are multiple lamps 22, they can emit the same light or different light.

[0028] In an embodiment not shown, the stimulation element 2 consists of two conductive elements 21, with at least a portion of the conductive elements 21 disposed on the outer surface of the housing 1. When the two conductive elements 21 come into contact with the human body, the battery, the two conductive elements 21, and the human tissue can form a current loop. The conductive elements 21 can directly apply electrical pulses to the human body to perform microcurrent therapy. The circuit board 5 can control the current output from the power supply 3 to the conductive elements 21 according to the pressure detected by the pressure sensor 42, thereby adjusting the current intensity applied to the human body by the conductive elements 21.

[0029] In this embodiment, the pressure sensor 42 is used to detect the pressure applied by the user to the positioning part 41 and converts the pressure signal into an electrical signal, which is then transmitted to the circuit board 5. When the user presses the positioning part 41, the pressure is transmitted to the sensitive element inside the pressure sensor 42, causing deformation or a change in charge distribution in the sensitive element, thereby generating a change in resistance or voltage corresponding to the pressure magnitude. The pressure sensor 42 can be a commercially available piezoresistive pressure sensor 42, piezoelectric pressure sensor 42, or other similar sensors. The pressure sensor 42 is positioned adjacent to the positioning part 41, meaning that there is a small gap between the pressure sensor 42 and the positioning part 41, or that the pressure sensor 42 is in direct contact with the positioning part 41, so that when the user presses the positioning part 41, the pressure on the positioning part 41 can be transmitted to the pressure sensor 42.

[0030] In one embodiment, reference Figure 2 The positioning part 41 is conductive; the stimulation element 2 includes a conductive element 21, at least a portion of which is exposed on the outer surface of the housing 1, facilitating direct contact between the conductive element 21 and human skin. The conductive element 21 and the positioning part 41 together form a pair of microcurrent electrodes. Firstly, the conductive element 21 in the stimulation element 2 is used to output microcurrents to the skin for physiotherapy. The main function of the positioning part 41 is for the user to press to adjust the current magnitude. By designing the positioning part 41 to be conductive, it serves as both a pressure adjustment interface and a conductive electrode, forming a pair of microcurrent electrodes with the other conductive element 21. The positioning part 41 achieves integrated "current adjustment and physiotherapy output" functions. The positioning part 41 both transmits pressure and participates in the physiotherapy output, eliminating the need for additional dedicated electrodes for the current adjustment component 4, simplifying the structure and improving the structural compactness of the physiotherapy device 100. Secondly, when the user adjusts the current by pressing the positioning part 41, their finger naturally contacts the positioning part 41, while another conductive element 21 contacts the skin, thus forming a microcurrent circuit. The current adjustment intensity and the receiving of physiotherapy can be completed in the same action, without switching gestures or interrupting the treatment process, improving the smoothness of the operation. Thirdly, since the positioning part 41 is both a pressure adjustment interface and a microcurrent output electrode, when the user's finger contacts the positioning part 41, the current flows into the body through the finger and forms a circuit with the other conductive element 21. This design creates a direct mapping between the user's pressing pressure and the intensity of the received microcurrent stimulation. For example, the harder the user presses, the greater the current and the stronger the stimulation; or, the harder the user presses, the smaller the current and the weaker the stimulation. The user can intuitively perceive and control the intensity of the physiotherapy by their own pressing force, forming a closed-loop feedback, significantly improving the intuitiveness and convenience of operation.

[0031] In one embodiment, the positioning part 41 may be made of conductive metal materials such as stainless steel, copper alloy, or copper metal.

[0032] In one embodiment, a conductive layer is provided on the outer surface of the positioning part 41. The conductive layer can be a metal layer with good conductivity, such as a gold layer, a silver layer, or a copper layer. The conductive layer can be formed on the positioning part 41 by electroplating or sputtering.

[0033] In one embodiment, reference Figures 2-7 The housing 1 has a receiving cavity 11, and a mounting hole 12 communicating with the receiving cavity 11 is provided on the housing 1. The pressure sensor 42 is located in the receiving cavity 11, and the positioning part 41 is movably disposed in the mounting hole 12. When the positioning part 41 is pressed, it can move relative to the mounting hole 12 and squeeze the pressure sensor 42. In this embodiment, the pressure sensor 42 can be fixed to the inner wall of the receiving cavity 11 by means of screw connection, snap connection, welding, adhesive connection, etc., or it can be fixed to the bracket 9 in the receiving cavity 11. The wall of the mounting hole 12 can serve as a guide wall, and the positioning part 41 can move along the center line of the mounting hole 12 when pressed. Preferably, a limiting ring 121 is provided at the edge of the mounting hole 12. The limiting ring 121 protrudes inward from the hole wall of the mounting hole 12 and enters the mounting hole 12. The positioning part 41 includes a pressing plate 411 and a locking block 412 connected to each other. The pressing plate 411 is located in the through hole of the limiting ring 121 for the user to press. The locking block 412 is located in the mounting hole 12 and is closer to the pressure sensor 42 than the limiting ring 121. The limiting ring 121 is used to prevent the positioning part 41 from disengaging from the mounting hole 12.

[0034] In one embodiment, reference Figure 11 and Figure 12 An elastic reset member 43 is provided between the pressure sensor 42 and the positioning part 41. One end of the elastic reset member 43 abuts against the pressure sensor 42, and the other end abuts against the positioning part 41. When the positioning part 41 is pressed, it moves towards the pressure sensor 42 and squeezes the elastic reset member 43, which then transmits the pressure to the pressure sensor 42. When the pressure applied to the positioning part 41 is removed, the elastic reset member 43 restores its elastic deformation and drives the positioning part 41 to move back to its initial position. The elastic reset member 43 can be a spring, a sheet spring, a spring pin, etc.

[0035] In one embodiment, reference Figure 12 The mounting hole 12 has multiple spaced slots 122 on its wall, arranged sequentially along the center line of the mounting hole 12. Each slot 122 corresponds to a pressure level, and each pressure level corresponds to a current output to the stimulation element 2. When the positioning part 41 moves along the center line of the mounting hole 12, the locking block 412 of the positioning part 41 can be inserted into the slot 122 to fix the positioning part 41 in the position of the corresponding pressure level, making it convenient for the user to select the pressure level according to their needs. Furthermore, the outer surface of the pressing plate 411 is provided with a pull strip 413, which the user can pull outward to move the positioning part 41 to the initial position.

[0036] In one embodiment, reference Figure 10 The housing 1 has a receiving cavity, in which the pressure sensor 42 is fixed. A positioning part 41 is fixed to the cavity wall and protrudes from the outer surface of the housing 1. The positioning part 41 is elastic and can undergo elastic deformation when pressed to compress the pressure sensor 42. In this embodiment, the pressure sensor 42 can be fixed to the inner wall of the receiving cavity by means of screw connection, snap-fit ​​connection, welding, adhesive connection, etc., or it can be fixed to a bracket in the receiving cavity. The positioning part 41 can be made of elastic silicone, elastic rubber, etc., and can be fixed to the cavity wall of the receiving cavity 11 by means of adhesive connection, thermoforming, injection molding, etc. On the one hand, the positioning part 41 is elastic; when pressed, it can undergo elastic deformation and compress the pressure sensor 42. After the user's hand leaves the positioning part 41, it can recover its elastic deformation, eliminating the need for an additional reset component to drive the positioning part 41 back to its initial state, thus saving on the number of parts. On the other hand, the positioning part 41 is made of elastic material. The soft touch of elastic material is more skin-friendly and comfortable than hard buttons, which is especially suitable for application scenarios that require long-term or frequent pressing and adjustment, and can reduce finger fatigue.

[0037] Preferably, the positioning part 41 can be made of conductive elastic materials such as conductive silicone, conductive rubber, conductive styrene block copolymer, and conductive polyurethane. The positioning part 41 is in close contact with the pressure sensor 42, and the conductive element 21 and the positioning part 41 together form a pair of microcurrent electrodes. Firstly, the positioning part 41 is made of conductive elastic material, which improves the sealing and pressing comfort of the positioning part 41 while integrating the functions of "current regulation and physiotherapy output". Secondly, traditional pressing structures use hard buttons and return springs, requiring pressure to pass through the hard button and return spring before being transmitted to the pressure sensor 42, resulting in a long pressure transmission path. In this embodiment, however, there is no need for an additional reset element to drive the positioning part 41 back to its initial state; the pressing pressure is directly transmitted from the positioning part 41 to the pressure sensor 42, resulting in a shorter force transmission path. This reduces energy loss and mechanical lag during pressure transmission, thereby improving the response speed of the pressure sensor 42.

[0038] Preferably, the positioning part 41 is integrally formed on the cavity wall of the receiving cavity 11 and is seamlessly connected to the cavity wall of the receiving cavity 11. There is no gap between the positioning part 41 and the housing 1, so there is no need to set an additional seal to seal the gap between the positioning part 41 and the housing 1, which saves the number of parts while ensuring the sealing performance.

[0039] In one embodiment, reference Figure 10The physiotherapy device 100 also includes a cover 6, which is fitted onto the housing 1. The opening edge of the cover 6 has a positioning notch 61 for the positioning part 41 to engage. The cover 6, fitted onto the housing 1, can protect the housing 1. The cover 6 can be detachably fitted onto the housing 1 by means of a snap-fit ​​structure, magnetic structure, etc. The positioning notch 61 can engage with the positioning part 41 to restrict the rotation of the cover 6 relative to the housing 1.

[0040] In one embodiment, reference Figures 3-7 The physiotherapy device 100 also includes an electrically controlled on / off element 7. The pressure sensor 42 is electrically connected to the circuit board 5 through the electrically controlled on / off element 7. The housing 1 includes a first housing 13 and a second housing 14. The first housing 13 is movably disposed on the second housing 14 to switch between a first position and a second position. When the first housing 13 is in the first position, the first housing 13 triggers the electrically controlled on / off element 7 to open, so that the pressure sensor 42 and the circuit board 5 are electrically connected. When the first housing 13 is in the second position, the first housing 13 triggers the electrically controlled on / off element 7 to close, so that the pressure sensor 42 and the circuit board 5 are electrically disconnected. When the pressure sensor 42 is always electrically connected to the circuit board 5, the current may change if the user presses the positioning part 41 at any time. However, in actual use scenarios, the user may only need a fixed amount of current output, or accidentally touch the positioning part 41 when performing operations such as holding, moving, or storing, resulting in unexpected changes in current, affecting the physiotherapy effect or causing discomfort. In this embodiment, an electrically controlled on / off element 7 is provided. When current adjustment is needed, the user can move the first housing 13 to a first position, triggering the electrically controlled on / off element 7 to open, thus electrically connecting the pressure sensor 42 and the circuit board 5. At this time, the user can adjust the current magnitude by pressing the positioning part 41. When current adjustment is not needed, the user can move the first housing 13 to a second position, triggering the electrically controlled on / off element 7 to close, thus electrically blocking the pressure sensor 42 and the circuit board 5. At this time, pressing the positioning part 41 is ineffective, and the current intensity remains constant. This design allows the user to turn the current adjustment function on or off by changing the position of the first housing 13 according to actual needs, improving the safety and controllability of use. In this embodiment, the electrically controlled on / off element 7 can be a commercially available DIP switch, micro switch, etc., and is not limited thereto.

[0041] In one embodiment, reference Figure 8 and Figure 9The first housing 13 is movable relative to the second housing 14 along a first direction. The first housing 13 is provided with a first latching member, and the second housing 14 is provided with a second latching member that cooperates with the first latching member. One of the first and second latching members is an insertion block 141, and the other is a slot 131. The slot 131 includes a first slot 1311 and a second slot 1312 spaced apart along the first direction. When the first housing 13 is in a first position, the insertion block 141 is inserted into the first slot 1311; when the first housing 13 is in a second position, the insertion block 141 is inserted into the second slot 1312.

The second fastening element is a plug 141, which is located on the outer wall of the second housing 14. The first direction w is parallel to the central axis of the second housing 14. The electronic control switching element 7 is a DIP switch, which is fixed on the bracket 9 inside the housing 1. The DIP switch has a lever 71. A groove 132 is provided on the inner wall of the first housing 13. The lever 71 is inserted into the groove 132, and the groove 132 can drive the lever 71 to move. When the first housing 13 is in the first position, the lever 71 is in the initial position relative to the second housing 14. At this time, the DIP switch is turned on, and the pressure sensor 42 and the circuit board 5 are electrically connected. Pulling the first housing 13 causes it to slide along the first direction to the second position. When the first housing 13 moves, it drives the lever 71 to move synchronously. At this time, the DIP switch is turned off, and the pressure sensor 42 and the circuit board 5 are electrically disconnected.

[0045] In one embodiment, reference Figure 3 and Figure 6 The housing 1 is provided with a liquid outlet 15, a liquid inlet 16, and a liquid guiding channel 17 connecting the liquid outlet 15 and the liquid inlet 16. The liquid inlet 16 is used to communicate with a container, which can be used to store skin care liquid. The physiotherapy device 100 also includes a pumping component 8, which is used to pump the liquid in the container to the liquid guiding channel 17 and the liquid outlet 15. The pumping component 8 is electrically connected to the power supply component 3 and the circuit board 5 respectively. The circuit board 5 can control the current output by the power supply component 3 to the pumping component 8 according to the pressure detected by the pressure sensor 42. In this embodiment, by controlling the current output by the power supply component 3 to the pumping component 8, the input power of the motor of the pumping component 8 is changed, thereby changing the pump speed or reciprocating frequency, and finally changing the volume of liquid pumped per unit time. By pressing the positioning part 41 and controlling the current of the pumping component 8 in real time, the on-demand supply of liquid is realized. Preferably, the circuit board 5 can control the current output from the power supply unit 3 to the stimulation element 2 and the pumping element 8 according to the pressure. The user does not need to operate the two control elements separately; they can adjust the liquid output and therapeutic intensity of the skincare product simultaneously by changing the pressure applied to the positioning part 41. In this embodiment, the pumping element 8 can be fixed in the housing 1, and can be a commercially available peristaltic pump, diaphragm pump, gear pump, etc.
