Detailed Implementation

[0034] 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.

[0035] [First Embodiment] like Figures 1-7 As shown, an embodiment of the present invention provides a facial beauty device 1. The facial beauty device 1 includes, for example, a first housing 10, a second housing 20, a constant temperature heating part 31, an elastic part 32, a facial massage part 40, a microcurrent control circuit 35, a circuit board 34, and a conductive sheet 11.

[0036] The first housing 10 has a first accommodating cavity 101. The second housing 20 is detachably connected to the first housing 10 and has a second accommodating cavity 201. The constant temperature heating part 31 is disposed at one end of the first housing 10 away from the second housing 20. The facial massage part 40 is disposed in the second housing 20, and one end of the facial massage part 40 protrudes outside the end of the second housing 20 away from the first housing 10. The elastic part 32 is disposed in the second accommodating cavity 201 and is elastically connected to the facial massage part 40. The microcurrent control circuit 35 is disposed in the first accommodating cavity 101. The circuit board 34 is disposed in the first accommodating cavity 101, and the microcurrent control circuit 35 is disposed on the circuit board 34 and electrically connected to the circuit board 34. The conductive sheet 11 is disposed on the side wall of the first housing 10, and the conductive sheet 11 is electrically connected to the microcurrent control circuit 35.

[0037] Specifically, the first housing 10 may be made of a composite material of ABS (Acrylonitrile Butadiene Styrene) and soft silicone, for example, with an ergonomic arc design for easy grip and operation. The first housing 10 has a first receiving cavity 101 inside, and the first housing 10 may be, for example, the main body of the gua sha-type facial beauty device. The first receiving cavity 101 is mainly used to house core electrical components such as the circuit board and power supply. The second housing 20 can be detachably connected to the first housing 10. The second housing 20 may be, for example, the head part of the gua sha-type facial beauty device. This detachable connection allows for easy replacement of the facial massage part 40 of the facial beauty device 1. The first housing 10 and the second housing 20 may employ a snap-fit ​​design, for example, with an annular groove at the lower end of the second housing 20 and an elastic snap at the corresponding upper end of the first housing 10. Pressing allows for disassembly and assembly, and after disassembly, the facial massage part 40 and the interior of the second housing 20 can be cleaned and replaced. The constant-temperature heating unit 31 can, for example, adopt a combination structure of Bian stone material and graphene heating element. The Bian stone is located at the end of the first housing 10 away from the second housing 20, that is, at the lower end of the first housing 10. The Bian stone directly contacts the facial skin, and then the graphene heating element provides a stable heat source to achieve constant-temperature heat therapy. The Bian stone of the constant-temperature heating unit 31 can be fixed to the lower end of the first housing 10, for example, by a high-temperature resistant silicone ring. The graphene heating element adheres to the back of the Bian stone to ensure that heat is evenly conducted to the surface of the Bian stone. The facial massage unit 40 can, for example, be a facial scraping tool or a facial acupressure tool, which is, for example, a conductive metal component. The facial scraping tool is used for scraping the user's face and neck, while the facial acupressure tool can, for example, perform point-to-point massage on the user's facial acupoints. The specific type of the facial massage unit 40 can be changed and used according to the user's different needs; no specific limitation is made here. The elastic part 32 can be, for example, a pressure spring, and its length can be, for example, 8-12 mm. In its natural state (i.e., when the tip of the facial massage part 40 is not being used for beauty treatments or pressing), the elastic part 32 naturally relaxes, thereby abutting against and allowing the tip of the facial massage part 40 to protrude 2-3 mm from the end of the second housing 20 away from the first housing 10. When the user presses the facial beauty device 1 onto acupoints on the face, the elastic part 32 compresses, causing the tip of the facial massage part 40 to compress towards the second receiving cavity 201 until the bottom of the facial massage part 40 contacts the second housing 20, with the buffer stroke adapted to the pressure tolerance range of the facial skin. When released, the elasticity of the elastic part 32 causes the tip of the facial massage part 40 to return to its original position, protruding 2-3 mm from the end of the second housing 20 away from the first housing 10.Furthermore, when the user presses, the elastic force of the elastic part 32 requires the tip of the facial massage part 40 to maintain a significant pressure to balance the elastic force. This significant pressure interacts with the facial acupoints in contact with the fan-shaped scraping head 42, causing the fan-shaped scraping head 42 to apply considerable pressure to the acupoints, thereby effectively stimulating deep acupoints and enhancing the acupoint stimulation effect. The conductive sheet 11 is made of medical-grade conductive silicone.

[0038] When a user touches or holds the facial beauty device 1, the user holds and touches the conductive sheet 11, forming a first conductive area on the conductive sheet 11. Then, the user presses the top of the facial beauty device 1 against the user's face, forming a second conductive area at the top of the facial massage part 40. When the facial massage part 40 is squeezed by the face, the bottom end of the facial massage part 40 compresses and squeezes the elastic part 32. The other end of the facial massage part 40 is compressed into the first accommodating cavity 101 and contacts and connects with the circuit board 34. Since the circuit board 34 is electrically connected to the microcurrent control circuit 35, both the circuit board 34 and the microcurrent control circuit 35 act as conductors. When the microcurrent control circuit 35 contacts the first conductive area and the second conductive area respectively, the human body can act as a conductor to connect the first connection terminal and the second connection terminal, controlling the on / off state of the microcurrent control circuit 35. When the microcurrent control circuit 35 is on, the microcurrent control circuit 35 generates a microcurrent, which reaches the top of the facial massage part 40 from the bottom end, and then stimulates the user's face. Therefore, when the user holds (contacts) the conductive sheet 11 while the facial massage unit 40 contacts the user's facial skin, the control switch is turned on. When either contact is separated, or both are separated, the control switch is turned off, enabling automatic opening and closing. This makes it convenient and safe to use. The microcurrent generated by the microcurrent control circuit 35 stimulates the facial skin, promoting collagen production, improving fine lines and sagging, and relaxing tense facial muscles. It is suitable for users with early signs of aging such as facial puffiness, mild facial contour sagging, and the initial appearance of fine lines.

[0039] This application provides a conductive sheet 11 on the first housing 10, with one end of the facial massage part 40 exposed at the end of the second housing 20 away from the first housing 10. Specifically, the first conductive area of ​​the microcurrent control circuit 35 is on the conductive sheet 11, and the second conductive area is located at one end of the facial massage part 40. When the first and second conductive areas contact the microcurrent control circuit 35 and the circuit board 34, and the user holds (contacts) the conductive sheet 11 and one end of the facial massage part 40 to contact the user's facial skin, the human body acts as a conductor to connect the microcurrent control circuit 35, generating a microcurrent to stimulate the user's facial skin. When the first and / or second conductive areas separate and contact each other, the microcurrent control circuit 35 can be disconnected. Simultaneously, a constant-temperature heating element is provided to heat the face, and the facial massage part stimulates the user's facial skin and acupoints, thereby fulfilling various user needs and enhancing the beauty effect.

[0040] Furthermore, such as Figure 3 , Figure 4 , Figure 8 and Figure 9As shown, the facial beauty device 1 also includes a control chip 37, which is disposed on the circuit board 34 and electrically connected to the micro-current control circuit 35. The micro-current control circuit 35 includes: a DC high-voltage input terminal HV, an auxiliary DC high-voltage input terminal HV′, a first control signal input terminal HV_SW, a second control signal input terminal HV_N, a first AC output terminal HV_OUT+, a second AC output terminal HV_OUT-, a first PNP transistor Q1, a second PNP transistor Q2, a first NPN transistor Q3, a second NPN transistor Q4, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, and a sixth resistor R6. In this configuration, the emitter E of the first PNP transistor Q1 is connected to the DC high-voltage input terminal HV, the collector C of the first PNP transistor Q1 is connected to the first AC output terminal HV_OUT+, and the base B of the first PNP transistor Q1 is connected to the collector C of the first NPN transistor Q3. The first resistor R1 is connected in series between the base B of the first PNP transistor Q1 and the collector C of the first NPN transistor Q3. The base B of the first NPN transistor Q3 is connected to the control... The control signal input terminal HV_SW is connected, the emitter E of the first NPN transistor Q3 is grounded, and the collector C of the first NPN transistor Q3 is connected to the second AC output terminal HV_OUT-. The second resistor R2 is connected in series between the base B of the first NPN transistor Q3 and the first control signal input terminal HV_SW, and the third resistor R3 is connected in parallel between the base B and the emitter E of the first NPN transistor Q3. The collector C of the second PNP transistor Q2 is connected to the first PNP transistor. The collector C of the PNP transistor Q1, the first AC output terminal HV_OUT+, and the base B of the second NPN transistor Q4 are connected; the emitter E of the second PNP transistor Q2 is grounded, and the base B of the second PNP transistor Q2 is connected to the second control signal input terminal HV_N; the fourth resistor R4 is connected in series between the collector C of the second PNP transistor Q2 and the base B of the second NPN transistor Q4; the fifth resistor R5 is connected in parallel between the emitter E and the base B of the second PNP transistor Q2. The sixth resistor R6 is connected in series between the base B of the second NPN transistor Q2 and the second control signal input terminal HV_N; the collector C of the second NPN transistor Q4 is connected to the second AC output terminal HV_OUT- and the collector C of the first NPN transistor Q3, respectively, and the emitter E of the second NPN transistor Q4 is connected to the auxiliary DC high voltage input terminal HV′; the first control input terminal HV_SW and the second control input terminal HV_N are electrically connected to the control chip 37.The control chip 37 may be, for example, an STM32 series microcontroller, and its specific circuit composition may be as follows. Figure 12 As shown, it is integrated in the central area of ​​the circuit board 34 and electrically connected to the microcurrent control module 35 via pins.

[0041] The working principle of the micro-current control circuit is as follows: 1. DC to AC conversion process: When HV_SW is high and HV_N is low: Q3 is turned on, then Q1 is turned on (the base of the PNP transistor is pulled low), Q2 is turned off, and then Q4 is turned off; at this time, HV is output to HV_OUT+ through Q1, HV_OUT- is grounded, and the positive half-cycle voltage is output; When HV_SW is low and HV_N is high: Q3 is off, then Q1 is off, Q2 is on, then Q4 is on (the base of the NPN transistor is pulled high); at this time, HV_OUT+ is connected to HV′ through Q4, outputting the negative half-cycle voltage; Repeat the above process, with Q1 and Q2 alternately conducting, and HV_OUT+ / - outputting a periodic AC signal.

[0042] 2. Frequency adjustment process: The control chip 37 controls the switching frequency of Q1 and Q2 by adjusting the level switching period of HV_SW and HV_N (i.e., the frequency of the PWM signal), thereby changing the frequency of the output AC power.

[0043] Furthermore, such as Figures 1-6As shown, the facial massage unit 40 includes a fan-shaped scraping head 42 and a scraping body 41. The scraping body 41 is located in the second accommodating cavity 201. The fan-shaped scraping head 42 is disposed at one end of the scraping body 41, and the end of the fan-shaped scraping head 42 away from the scraping body 41 protrudes from the end of the second housing 20 away from the first housing 10. One end of the elastic part 32 is fixedly connected to the end of the second housing 20 near the first housing 10, and the other end of the elastic part 32 is elastically connected to the other end of the fan-shaped scraping head 42 near the scraping body 41. Specifically, the fan-shaped scraping head 42 can, for example, be made of medical-grade metal in a fan shape. The end face of the fan-shaped structure that contacts the skin can be designed as an arc-shaped surface to avoid scratching the skin. The scraping body 41 is a hollow cylindrical structure. The scraping body 41 can be fixed to the fan-shaped scraping head 42 by threads, for example, to facilitate the replacement of different shaped fan-shaped scraping heads (such as an arc-shaped surface or a flat surface that contacts the skin) to suit different care areas. Of course, in other embodiments, the scraping body 41 and the fan-shaped scraping head 42 can be integrally formed. When the user presses the facial beauty device 1 on the acupoints on the face, the elastic part 32 is compressed, causing the fan-shaped scraping head 42 to be compressed towards the second receiving cavity 201 until the lower end of the fan-shaped scraping head 42 contacts the second housing 20. The buffer stroke is adapted to the pressure tolerance range of the facial skin. When released, the elasticity of the elastic part 32 causes the fan-shaped scraping head 42 to return to its original position, 2-3 mm away from the end of the second housing 20 and away from the first housing 10. Furthermore, when the user presses, due to the elastic force of the elastic part 32, the fan-shaped scraping head 42 requires a large amount of force to balance the elastic force. This large force interacts with the facial acupoints in contact with the fan-shaped scraping head 42, allowing the fan-shaped scraping head 42 to apply a large amount of force to the facial acupoints, thereby effectively stimulating deep acupoints and enhancing the acupoint stimulation effect.

[0044] In this embodiment, as Figure 5 and Figure 6As shown, the fan-shaped scraping head 42 includes a fan-shaped arc surface 421 and two contact arc surfaces 422. Contact arc surfaces 422 are provided on both sides of the fan-shaped arc surface 421. When the user uses the facial beauty device 1, the fan-shaped arc surface 421 can be held by the hand in the holding area 102, and then directly pressed against the user's face. The user can then perform scraping by moving the fan-shaped arc surface 421 up and down or left and right. The fan-shaped arc surface 421 can adapt to the contours of the user's face. The curved surface 421 is disposed on the front of the fan-shaped scraping head, and the contact curved surface 422 is disposed on the side of the fan-shaped scraping head 42, that is, the back. The arc shape of the contact curved surface 422 can be adapted to the contour of the user's chin, that is, the contact curved surface 422 can be used to contact the user's chin or jawline, and can be used to perform scraping treatment on the user's chin. The fan-shaped scraping head 42 can perform scraping treatment on both the face and the chin, thus expanding the application range of the facial beauty device.

[0045] Furthermore, such as Figures 3-6 As shown, the facial beauty device 1 also includes a mounting part 60, which is disposed within the second accommodating cavity 201. An elastic part 32 is disposed within the mounting part 60, and one end of the mounting part 60 abuts against the end of the first housing 10 near the second housing 20. A portion of the scraping body 41 is disposed within the mounting part 60 and passes through the elastic part 32. The mounting part 60 can be, for example, a cylindrical hollow structure, integrally molded from ABS engineering plastic. The outer diameter of this cylindrical hollow structure matches the inner diameter of the second accommodating cavity 201. For example, the gap between the outer diameter of the cylindrical hollow structure and the inner diameter of the second accommodating cavity 201 is 0.1-0.2 mm, ensuring no loosening after installation and facilitating disassembly and cleaning. The mounting part 60 has reserved space for the installation of the elastic part 32 and the scraping body 41, enabling precise positioning of the components. The elastic part 32 can be completely accommodated within the mounting part 60. The inner wall of the mounting part may be provided with an axial guide groove to prevent circumferential rotation of the elastic part 32 during extension and retraction, ensuring that the pressure buffer direction is aligned with the axis of the scraping body 41. The middle and lower parts of the scraping body 41 pass through the elastic part 32 with a clearance fit. This ensures smooth extension and retraction of the scraping body 41 along its axis while preventing wobbling through the radial limit provided by the elastic part 32, achieving a synergistic effect of pressure balance and precise scraping. The mounting part 60 allows the elastic part 32 and the scraping body 41 to form a modular assembly, facilitating production assembly and subsequent maintenance. When either the elastic part 32 or the scraping body 41 is damaged, the module can be replaced individually, reducing operating costs.

[0046] Furthermore, the elastic part 32 includes a spring member 321 and a spring limiting member 322. A groove 62 is provided on the side wall of the mounting part 60 at the end away from the first housing 10. The spring limiting member 322 is disposed within the groove 62 and slidably connected to it. One end of the spring member 321 is connected to the spring limiting member 322, and the other end of the spring member 321 abuts against the end of the mounting part 60 near the first housing 10. The spring member 321 can be, for example, a compression spring made of stainless steel, which can adapt to the pressure requirements of facial scraping. It can both buffer the manually applied force through elastic deformation and provide sufficient rebound force to achieve deep fascia stimulation. The groove 62 is provided on the side wall of the mounting part 60 at the end away from the first housing 10. The groove 62 can be, for example, an opening in the side wall of the mounting part 60. The spring limiting member 322 can be, for example, a cylindrical structure with a limiting post structure. The cylindrical structure abuts against one end of the spring member 321, and the limiting post can be, for example, located on the outer periphery of the cylindrical structure. The limiting post is embedded in the groove 62 to achieve a sliding connection, ensuring that the spring limiting member 322 can only extend and retract axially and cannot rotate circumferentially. One end of the spring member 321 is fixed to the side of the spring limiting member 322 near the first housing 10 by welding or snap-fit, and the other end abuts against the annular step inside the mounting part 60. After installation, the spring member is in a pre-compressed state, ensuring that the scraping body 41 is always under elastic support and preventing loosening. For example, an annular limiting member can be provided on the upper part of the scraping body 41, which can abut against the upper end of the mounting part 60 when the spring member 321 is compressed, thereby abutting the upper end of the groove 62, limiting the sliding stroke of the spring limiting member 322, preventing the spring member 321 from being over-compressed or stretched and causing elastic failure, and extending its service life.

[0047] Furthermore, such as Figure 6As shown, the spring limiting member 322 includes a limiting member fixing cap 3222 and a limiting post 3221. The scraping body 41 is provided with a limiting through hole 411 corresponding to the limiting post 3221. One end of the limiting post 3221 passes through the limiting through hole 411 from inside the scraping body 41 and protrudes outside the limiting member fixing cap 3222. The limiting post 3221 is disposed in the groove 62 and is slidably connected to the groove 62. In this embodiment, the lower end of the spring member 321 may be provided with a second washer 324, for example. The second washer 324 may be disposed, for example, at the bottom end inside the mounting part 60, so that there is a buffer between the spring member 321 and the bottom of the mounting part 60. The limiting post 3221 may include, for example, a limiting post mounting cylinder and a cylinder. A first washer 323 is provided between the limiting member fixing cap 3222 and the limiting post mounting cylinder to provide cushioning. The limiting post 3221 and the limiting member fixing cap 3222 may be integrally formed. The limiting post 3221 is a circular cylinder, its length slightly longer than the thickness of the scraping body 41, ensuring effective limiting after passing through the limiting through hole 411. The limiting member fixing cap 3222 may be, for example, an annular disc structure, with an outer diameter matching the inner diameter of the mounting part 60. Its side away from the limiting post 3221 has anti-slip textures, facilitating pressing during assembly and enhancing contact stability with the scraping body 41. The limiting through hole 411 on the scraping body 41 is a circular hole with a diameter that matches the outer diameter of the limiting post 3221. This ensures that the limiting post 3221 passes smoothly through while achieving precise radial positioning, preventing the scraping body 41 from shifting during movement. The sliding connection between the limiting post 3221 and the groove 62 can be, for example, a clearance fit. A very small gap, such as 0.05-0.1 mm, between the slider and the groove wall ensures smooth operation during scraping, achieving both light-force operation and deep stimulation.

[0048] Furthermore, such as Figures 3-6As shown, the facial beauty device 1 further includes a connecting part 50. One end of the connecting part 50 is fixedly connected to the first housing 10, and the other end of the connecting part 50 is detachably connected to the second housing 20. The mounting part 60 has a mounting through hole 61 at one end near the first housing 10. The end of the scraping body 41 away from the fan-shaped scraping head 42 passes through the mounting through hole 61 and abuts against the connecting part 50. The connecting part 50 has a connecting through hole 52. The end of the scraping body 41 away from the card holder 45 is connected to the connecting part 50 and passes through the connecting through hole 52. The first accommodating cavity 101 is connected to the second accommodating cavity 201 through the connecting through hole 52. The connecting part 50 can be integrally molded from a rigid material, for example. One end of the connecting part 50 can be sleeved or snapped onto the upper end of the first housing 10, and the other end of the connecting part 50 can be provided with an annular thread, for example, to connect with the second housing 20 through threaded engagement, ensuring that there is no looseness after the first housing 10 and the second housing 20 are connected. The connecting through hole 52 can be, for example, a through hole provided on the limiting block. The diameter of the connecting through hole 52 can be adapted to, for example, the outer diameter of the scraping body, to ensure that the facial massage part 40 can be smoothly retracted into the first receiving cavity 101, and to prevent the facial massage part 40 from shaking. The first receiving cavity 101 is connected to the second receiving cavity 201 through the connecting through hole 52, which facilitates the passage of the wires of the circuit board 34 and provides a wiring channel for the subsequent power supply of the facial massage part 40.

[0049] Furthermore, such as Figure 3 and Figure 7As shown, the constant temperature heating unit 31 includes a Bianstone contact element 311 and a heating element 312. The heating element 312 is thermally connected to the Bianstone contact element 311. The Bianstone contact element 311 and the heating element 312 are located in the end of the first housing 10 away from the second housing 20. The facial beauty device 1 also includes a temperature detection unit 33, which is disposed in the first accommodating cavity 101 and located on the circuit board 34. The temperature detection unit 33 is electrically connected to the heating element 312 and the control chip 37. The temperature detection unit 33 is used to detect the heating temperature of the heating element 312 and send it to the control chip 37. The control chip 37 is used to receive the heating temperature and determine whether the heating temperature is within a preset range. When it is determined that the heating temperature is not within the preset range, the current heating temperature of the heating element 312 is controlled so that the current heating temperature is within the preset range. The Bianstone contact element 311 can be, for example, Bianstone, and the heating element 312 can be, for example, a graphene heating pad. The Bianstone directly contacts the facial skin, and the graphene heating pad provides a stable heat source to achieve constant-temperature heat therapy. The temperature detection unit 33 can include, for example, a thermistor and a detection circuit. The thermistor can be, for example, in close contact with the back of the graphene heating pad, and the thermistor is electrically connected to the detection circuit. Figure 11 As shown, in this embodiment, the specific working principle of the detection circuit in the temperature detection unit 33 is as follows: Step 1: Temperature detection (conversion of thermistor to voltage signal) The circuit uses a voltage divider circuit with a thermistor and resistor R31 to convert temperature changes into a voltage signal detectable by the control chip 37. The circuit is powered by the BAT terminal of CON1. ​​The thermistor is connected in series with R31 and then grounded to form a voltage divider circuit. When the temperature of the heating element increases: the resistance of the thermistor decreases, and the voltage at node A2 increases; When the temperature of the heating element decreases: the resistance of the thermistor increases, and the voltage at node A2 decreases; The voltage signal of node A2 is sent to the analog-to-digital conversion pin of control chip 37. By reading this voltage value, control chip 37 can deduce the current temperature of the heating element.

[0050] Step 2: Temperature control: Based on the detected voltage (corresponding temperature), control chip 37 outputs a control signal HEAT_SW to control the on / off state of Q5, thereby controlling the power supply to the heating element. When the control chip 37 detects that the voltage of A2 is higher than the set threshold (corresponding to excessive temperature): the control chip 37 controls HEAT_SW to output a low level, the gate of Q5 has no driving voltage, and Q5 is turned off, controlling the heating element to turn off the power and stop heating. When the control chip 37 detects that the voltage of A2 is lower than the set threshold (corresponding to "low temperature"): the control chip 37 controls HEAT_SW to output a high level, the gate of Q5 obtains the driving voltage, Q5 is turned on, and the heating element is powered on and starts to heat up; Repeat the above process, Q5 is periodically switched on and off under the control of the control chip 37, so that the temperature of the heating element is maintained within the set constant temperature range.

[0051] The temperature detection unit 33 can be fixed to the circuit board 34 by welding, for example. The circuit board 34 is equipped with a temperature protection circuit. For example, when the heating temperature of the graphene heating element exceeds 60°C, the power supply to the heating element is automatically cut off to maintain the constant temperature heating of the constant temperature heating unit 31. The device fits the gripping area 102 of the first housing 10. When the user holds the device, their palm naturally contacts the conductive sheet 11, and then presses down to bring the fan-shaped scraping head 42 into contact with the face. Simultaneously, the end of the scraping body 41 away from the fan-shaped scraping head 42 is compressed onto the circuit board inside the first accommodating cavity 101. This forms a current loop between the microcurrent module 35, the conductive sheet 11, the scraping body 41, and the fan-shaped scraping head 42, thereby triggering a microcurrent to care for the face. The conductive sheet 11 is electrically connected to the circuit board 34 through conductive adhesive. The surface of the conductive sheet 11 has an anti-slip texture, which improves conductivity stability and enhances friction during gripping, preventing the device from slipping during use. In this embodiment, the constant temperature heating part 31 further includes, for example, a base 313, which is connected to the lower end of the first housing 10. The Bianstone contact member 311 is disposed at the end of the base 313 away from the first housing. The heating element 312 may be disposed, for example, inside the base 313. The base 313 may be provided with, for example, a through hole, through which the heating element 312 extends into the Bianstone contact member 311.

[0052] Furthermore, the first housing 10 is also provided with a button portion 12. The button portion 12 is located on the side of the first housing 10 away from the conductive sheet 11 and corresponds to the conductive sheet 11. The facial beauty device 1 also includes a power supply portion 36, which is located in the first accommodating cavity 101 and adjacent to the circuit board 34. The button portion 12 is electrically connected to both the power supply portion 36 and the circuit board 34. The power supply portion can be, for example, a lithium battery, located in the first accommodating cavity 101 adjacent to the circuit board 34, and connected to the power interface of the circuit board 34 via a wire. It is fixed with a snap-fit ​​mechanism for easy replacement. The button portion 12 can be, for example, a power switch and a gear selector button. It is, for example, a silicone tactile button, located on the side of the first housing 10 away from the conductive sheet 11, adapted to the grip area 102, allowing the user's thumb to operate it naturally when holding it. In this embodiment, the button section 12 includes a first button 121 and a second button 122, which are spaced apart on the first housing 10. The first button 121 is electrically connected to the power supply section 36, and the second button 122 is electrically connected to the circuit board 34. A gripping area 102 is provided on the first housing 10, which is located near the constant temperature heating section 31. Part of the conductive sheet 11, the first button 121, and the second button 122 are located within the gripping area 102. The gripping area 102 is an arc-shaped area in the middle and bottom part of the first housing, and its surface is coated with an anti-slip silicone coating to conform to the curve of the palm, reducing fatigue during long-term gripping.

[0053] The first button 121 is used to control power on / off and mode switching (cyclically switching between microcurrent mode and constant temperature heating mode). The second button is used to adjust the intensity of each mode. When a button is pressed, it may be accompanied by a buzzer, providing clear feedback. Part of the conductive sheet 11, the first button 121, and the second button 122 are located within the grip area 102, making the operation concentrated and allowing all functions to be controlled without adjusting the grip posture.

[0054] Furthermore, the facial beauty device also includes, for example, a light-emitting part 13, which is disposed on the first housing and spaced apart from the button part 12. The light-emitting part 13 may include, for example, a first LED element 131 and a second LED element 132. The first LED element 131 is disposed below the first button 121, and the second LED element 132 may be disposed, for example, above the second button 122. The first LED element 131 may include, for example, a first LED, a second LED, and a third LED, and the second LED element 132 may include, for example, a fourth LED, a fifth LED, and a sixth LED. The light-emitting part 13 can be used to display the power level, indicate low battery, provide a charging indicator, etc., and can be controlled by the control chip 37. Figure 10 As shown, the control chip 37 controls the on / off states of different paths, thereby controlling the illumination of different LEDs. For example, the control logic of the control chip 37 can be as follows: press and hold the first button 121 for 2 seconds to power on (default micro-current mode 1, corresponding to one indicator light in the first LED component 131 lighting up); press the first button 121 briefly to cycle through the micro-current / constant temperature heating modes; after switching to the corresponding mode, press the second button 122 briefly to cycle through the corresponding mode 1-3. For example, the first LED component 131 includes a first LED, a second LED, and a third LED. When entering the default micro-current mode, pressing the second button 122 briefly switches between micro-current mode 1-3. At level 1, the first LED lights up; at level 2, the second LED lights up; and at level 3, the third LED lights up. If constant temperature heating mode is required, pressing the first button 121 briefly enters the constant temperature heating mode.

[0055] Furthermore, the first housing 10 is also provided with a charging through-hole 103 and a cover 38. The charging through-hole 103 is located between the conductive sheet 11 and the button portion 12, and the cover 38 is disposed on the charging through-hole 103 and covers it. The charging through-hole 103 can be, for example, a Type-C interface mounting hole, located between the conductive sheet 11 and the button portion 12, with a built-in Type-C charging interface supporting PD fast charging and DCP charging protocols. The cover 38 is a silicone dust plug, which is interference-fitted with the charging through-hole 103 and has a pluggable design. When not charging, it is inserted into the through-hole to prevent dust and liquid from entering the device and protect the charging interface. The circuit board 34 can be provided with a fast charging interface that supports fast charging. The fast charging interface can protrude from the charging through-hole 103. Specifically, the working process of the facial beauty device is as follows: Facial beauty device 1 is powered on: The user presses and holds the first button 121 for about 2 seconds to start the device. It defaults to EMS mode (current stimulation mode) level 1. At this time, the fourth LED in the second LED component 132 corresponding to EMS mode level 1 is lit. The EMS mode has a default timer of 10 minutes, which starts automatically from the start of EMS mode and the facial beauty device 1 can automatically turn off after 10 minutes.

[0056] EMS Mode Switching: Briefly press the second button 122 to switch the facial beauty device 1 from EMS mode 1 to mode 2. At this time, the LED light switches from the fourth LED to the fifth LED and lights up. Briefly press the second button 122 again to switch the facial beauty device 1 from EMS mode 2 to mode 3. At this time, the LED light switches from the fifth LED to the sixth LED and lights up.

[0057] Switching to Constant Temperature Heating Mode: Briefly press the first button 121 to switch the facial beauty device 1 from EMS mode to DHT mode (constant temperature heating mode). After switching, it defaults to constant temperature heating mode 1. At this time, the first LED in the first LED component 131 of the light-emitting part 13 is lit. The DHT mode has a default timer of 5 minutes, which is automatically timed from the start of DHT mode. The facial beauty device can automatically turn off after 5 minutes.

[0058] Constant temperature heating mode switching: Press the second button 122 briefly, and the facial beauty device 1 will switch from DHT mode 1 to 2. At this time, the LED light will switch from the first LED to the second LED. Press the second button 122 briefly again, and the facial beauty device 1 will switch from DHT mode 2 to 3. At this time, the LED light will switch from the second LED to the third LED.

[0059] Power off: Press and hold the first button 121 for about 2 seconds while the device is powered on to turn off all functions and turn off the light in the light-emitting part 13.

[0060] Other situations: 1. When the device is not powered enough, for example, when the voltage of the power supply unit 36 ​​is less than 3.4V, and the facial beauty device is in working condition, the indicator light corresponding to the current mode of the facial beauty device will flash. For example, if the current mode is EMS mode and the corresponding level is 2, the fifth LED will flash to remind the user that the facial beauty device is low on power.

[0061] 2. Power loss protection: When the facial beauty device is turned on and the power supply voltage is less than 3V, pressing and holding the first button 121 will prevent the device from turning on. All LEDs of the first LED component 131 and the second LED component 132 will flash 5 times in sync and then turn off.

[0062] 3. During charging: When the facial beauty device 1 is connected to the internal fast charging interface through the charging port and is being charged, that is, when the facial beauty device is connected to the charger, all the LEDs of the first LED element 131 and the second LED element 132 will flash in a breathing manner. The breathing manner can be, for example, the breathing manner of indicator lights in the prior art.

[0063] [Second Embodiment] The facial beauty device 1 provided in this embodiment is basically the same as the facial beauty device 1 provided in the first embodiment, except that the facial massage part 40 includes a pointer body 43 and a pointer head 44.

[0064] Specifically, such as Figures 13-16 As shown, the facial massage unit 40 includes a pointer head 44 and a pointer body 43. The pointer body 43 is located within the second accommodating cavity 201. The pointer head 44 is disposed at one end of the pointer body 43, with the end of the pointer head 44 away from the pointer body 43 protruding from the end of the second housing 20 away from the first housing 10. One end of the elastic part 32 is fixedly connected to the end of the second housing 20 near the first housing 10, and the other end of the elastic part 32 is elastically connected to the other end of the pointer head 44 near the pointer body 43. The pointer head 44 may be made of, for example, medical-grade stainless steel, and the end face in contact with the skin may be designed as an arc-shaped surface to avoid scratching the skin. The pointer body 43 has a hollow cylindrical structure and may be fixed to the pointer head 44 by threads, for example, to facilitate the replacement of pointer heads of different shapes (such as round heads or flat heads) to adapt to different care areas. Of course, in other embodiments, the pointer body 43 may be integrally formed with the pointer head 44. The elastic part 32 can be, for example, a pressure spring, and its length can be, for example, 8-12 mm. In its natural state (i.e., when the facial beauty device 1 is not being used for beauty treatments or pressing), the elastic part 32 naturally relaxes, thereby blocking and allowing the pointer tip to protrude 2-3 mm from the end of the second housing 20 away from the first housing 10. When the user presses the facial beauty device onto acupoints on the face, the elastic part 32 compresses, causing the pointer tip to compress 3-5 mm towards the second receiving cavity 201, with the buffer stroke adapted to the pressure tolerance range of the facial skin. When released, the elasticity of the elastic part 32 causes the pointer tip 44 to return to the position 2-3 mm from the end of the second housing 20 away from the first housing 10. Furthermore, when the user presses the acupoint, the elastic force of the elastic part 32 requires the pointer 44 to maintain a significant pressure to balance the elastic force. This significant pressure interacts with the acupoints on the face that are in contact with the pointer 44, causing the pointer 44 to apply considerable pressure to the acupoints, thereby effectively stimulating deep acupoints and enhancing the acupoint stimulation effect. This application provides an elastic part 32 within the second housing 20, which is elastically connected to the facial massage part 40. The cushioning design of the elastic part 32 allows the massage pressure of the facial massage part 40 to automatically adapt to the skin's tolerance. No precise manual control of the force is required; only gentle manual pressing is needed. This allows the pointer tip 44 of the acupoint pointer part to contact the acupoints on the face. Furthermore, the elasticity of the elastic part 32 ensures that the applied force effectively stimulates the deep fascia while avoiding skin damage.

[0065] Furthermore, such as Figures 13-16 As shown, the facial massage unit 40 also includes a retainer 45 and a pointer head fixing cap 46. The pointer head fixing cap 46 is connected to the retainer 45, and both the pointer head fixing cap 46 and the retainer 45 are located within the second receiving cavity 201. The retainer 45 is located between the pointer head 44 and the pointer body 43. One end of the pointer head 44 near the pointer body 43 passes through the pointer head fixing cap 46 and connects to the retainer 45. The other end of the elastic part 32 abuts against the side of the retainer 45 near the pointer body 43. In this embodiment, the retainer 45 and the pointer head fixing cap 46 can be connected, for example, by a third washer 47, which can be used to buffer the connection between the retainer 45 and the pointer head fixing cap 46. The retainer has a circular stepped structure and can be made of, for example, ABS material. It has a threaded hole in the center, and the end of the pointer head 44 near the pointer body 43 has an external thread. After passing through the pointer head fixing cap 46, it is threadedly connected to the retainer 45, making it secure and not easy to fall off. The pointer head fixing cap 46 has a ring-shaped structure with an anti-slip texture on its inner wall. It is fitted onto the connection between the pointer head 44 and the holder 45 to further enhance the fixing effect and prevent the pointer head 44 from shaking. The other end of the elastic part 32 abuts against the side of the holder 45 near the pointer body 43. The abutment may have a circular groove, for example, in which the end of the elastic part 32 is embedded to prevent the elastic part from shifting during the extension and contraction process, thus ensuring the stability of the pressure buffer.

[0066] Furthermore, it is understood that the foregoing embodiments are merely illustrative examples of the present invention. Provided that the technical features do not conflict, the structure is not contradictory, and the purpose of the invention is not violated, the technical solutions of the various embodiments can be arbitrarily combined and used.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
