[0002] As people's interactions in society become more and more extensive and various social activities become more frequent, more and more people pay more attention to their appearance. With the continuous development of the economy and the continuous advancement of science and technology, more and more care devices for human skin beauty (such as massagers, shavers, etc.) have emerged.

[0003] However, existing care device products generally have only one or one type of care module, that is, one care device product can only perform one beauty operation, resulting in a single function of the care device product.

[0047] The present application provides a multifunctional care device, which is used to perform multiple beauty treatments on human skin, such as shaving hair, irradiating the skin to promote blood circulation, contacting the skin to remove acne or promote skin metabolism, etc., so that one device can be used for multiple purposes, achieving the purpose of meeting the user's usage needs in different usage scenarios without having to replace the care device.

[0048] See also Figure 1 and Figure 2 , Figure 1 A schematic diagram of a multifunctional nursing device 10 provided in one embodiment of the present application is shown. Figure 2 An exploded schematic diagram of a multifunctional nursing device 10 is shown. The multifunctional nursing device 10 provided in one embodiment of the present application includes a body 100, a control module 200, a driving module 300, and a plurality of nursing modules 400, wherein the control module 200 is communicatively connected to the driving module 300, and any nursing module 400 can be detachably connected to the driving module 300, so that different nursing modules 400 can be replaced with each other. The control module 200 is used to control the operation of the driving module 300. When different nursing modules 400 are installed on the driving module 300, the different nursing modules 400 can be driven by the driving module 300 to realize different beauty functions.

[0049] Specifically, see Figure 2 In one embodiment, the control module 200 includes a battery 210 and a main control system 220 connected to the battery 210. The battery 210 is used to power the main control system 220. The main control system 220 can be, for example, a PCB board, which is used to provide a control signal to control the operation of the driving module 300; the driving module 300 includes a driving motor 310 and a transfer component 320. The driving motor 310 is used to provide power or provide an electrical signal. The transfer component 320 is used to transmit the power or electrical signal provided by the driving motor 310 to the care module 400, so that different care modules 400 can achieve different specific functions.

[0050] In some embodiments, Figure 1As shown, at least one care module 400 includes a first care element 401, and any care module 400 includes a second care element 402; the first care element 401 can rotate around its own central axis, and is used to shave hair or massage the skin, and the transfer component 320 can convert the power provided by the drive motor 310 into a suitable rotation speed that can enable the first care element 401 to work normally; the second care element 402 is used to emit light that can care for the skin (such as visible light of a specific wavelength) to achieve the function of irradiating the skin and promoting blood circulation of the skin. At this time, the transfer component 320 can transmit the electrical signal provided by the drive motor 310 to the second care element 402, so that the second care element 402 can emit light. For example, when the control module 200 controls the second care element 402 to emit red light with a wavelength of 633±10nm, it can inhibit inflammation by inhibiting cyclooxygenase, and at the same time promote blood circulation, stimulate collagen regeneration and reduce the formation of acne scars, which is suitable for acne skin, sensitive skin, and aging skin, and can repair wounds and improve allergic reactions; or when the control module 200 controls the second care element 402 to emit green light with a wavelength of 405-470nm, the green light can reduce inflammation, sterilize, and calm. It can also purify the skin, and has a certain effect on congestion and pain, which is suitable for acne skin, oily skin, and sensitive skin.

[0051] Furthermore, at least one care module 400 also includes a third care element 403, which is used to generate heat or microcurrent. When the third care element 403 is used to generate heat, the third care element 403 can use RF (Radio Frequency) technology to heat the skin, thereby heating the dermis tissue of the human skin and promoting the elasticity and vitality of collagen to achieve a beauty effect; when the third care element 403 is used to generate microcurrent, the third care element 403 can use EMS (Electrical Muscle Stimulation) technology to stimulate facial muscle contraction, thereby achieving the function of face slimming and beauty.

[0052] See also Figure 3In one embodiment, when the nursing module 400 includes the second nursing element 402 and the third nursing element 403, the nursing module 400 is provided with a first conductive element 404 and a second conductive element 405, and the first conductive element 404 and the second conductive element 405 are respectively connected to the second nursing element 402 and the third nursing element 403. Correspondingly, the transfer component 320 is provided with a first connecting terminal 321 and a second connecting terminal 322, and the driving motor 310 is provided with a third conductive element 311 and a fourth conductive element 312, one end of the first connecting terminal 321 is connected to the first conductive element 404, and the other end is connected to the third conductive element 311, and one end of the second connecting terminal 322 is connected to the second conductive element 405, and the other end is connected to the fourth conductive element 312, so as to realize the electrical connection between the driving module 300 and the second nursing element 402 and the third nursing element 403, so that the control module 200 can control the driving module 300 to realize electrical conduction with the second nursing element 402 and the third nursing element 403 respectively.

[0053] Further, when the care module 400 also includes a first care element 401, the first care element 401 is connected to a transmission assembly 406, and a transfer sleeve 313 is provided on the drive motor 310 and is passed through the transfer assembly 320. One end of the transfer sleeve 313 is connected to the transmission assembly 406, and the other end is connected to the output end of the drive motor 310, so that the control module 200 can control the drive motor 310 to drive the transmission assembly 406 to drive the first care element 401 to rotate around its own central axis.

[0054] Exemplarily, the first conductive element 404 , the second conductive element 405 , the third conductive element 311 and the fourth conductive element 312 may be conductive springs or other conductive elements, which are not specifically limited.

[0055] It is understandable that functions such as shaving hair, massaging, light beauty, heating skin or micro-current skin stimulation can be combined arbitrarily, so that different care modules 400 can have different beauty functions. It is also understandable that when the care module 400 only includes the second care element 402, the care module 400 is only provided with the first conductive element 404, the transfer component 320 is only provided with the first connecting terminal 321, and the drive motor 310 is only provided with the third conductive element 311, that is, the care module 400 does not have the second conductive element 405 and the transmission component 406, the transfer component 320 does not have the adapter sleeve 313 and the second connecting terminal 322, and the drive motor 310 does not have the fourth conductive element 312, which will not be described in detail here.

[0056] When it is necessary to replace a different care module 400, in order to facilitate the user to distinguish whether the care module 400 has been replaced, in a preferred embodiment, the second care element 402 in different care modules 400 can output different electrical signals, such as different current values ​​or voltage values, resistance values, etc., and the control module 200 is provided with an electrical signal checker. After the care module 400 is replaced, the electrical signals passing through different care modules 400 are different, so that the control module 200 can be used to identify different care modules 400 installed in the driving module 300 according to the different electrical signals output by the second care element 402. For example, in this embodiment, the second care element 402 is an LED lamp, and the number of LED lamps in different care modules 400 is different. After the care module 400 is replaced, the magnitude of the current passing through the LED lamp is different. The magnitude of the output current can be detected by the electrical signal checker to determine whether the care module 400 has been replaced.

[0057] See also Figure 1 Taking the multifunctional care device 10 provided in this embodiment as an example, the number of care modules 400 is three, and the three care modules 400 are respectively defined as a first care module 410, a second care module 420 and a third care module 430, wherein the first care module 410 and the second care module 420 both have a first care element 401, a second care element 402 and a third care element 403, the third care module 430 has a second care element 402 and a third care element 403, the first care element 401 of the first care module 410 is used for shaving hair, and the first care element 401 of the second care module 420 is used for massaging the skin.

[0058] Through the above configuration, the multifunctional care device 10 can be used for multiple purposes, and has beauty functions such as shaving hair, massaging, light beauty, heating skin or micro-current stimulation, so as to meet the use requirements of different scenarios. And when any care module 400 is connected to the driving module 300, and the control module 200 can identify different care modules 400 installed on the driving module 300, it is convenient for the user to judge whether the care module 400 has been replaced, which is convenient for the user to use.

[0059] It should be noted that the circuits used by the multifunctional care device 10 provided in the above embodiment to realize the two functions of heating the skin and microcurrent stimulation are the same circuit. Figure 1As shown, the body 100 of the multifunctional care device 10 is provided with a first control button 101, a second control button 102 and a third control button 103 connected to the control module 200. The first control button 101 and the second control button 102 are respectively used to drive the control module 200 to output different electrical signals to control the third care element 403 to generate heat or generate microcurrent. For example, when the user presses the first control button 101, the control module 200 can be driven to output an electrical signal that causes the third care element 403 to generate heat. When the user presses the second control button 102, the control module 200 can be driven to output an electrical signal that causes the third care element 403 to generate microcurrent. The third control button 103 is a switch button. When the third control button 103 is pressed, the control module 200 starts to work and can drive the first care element 401 and the second care element 402 to work. Of course, additional buttons can also be set to enable the control module 200 to control the first care element 401 and the second care element 402 to work, which is not limited here.

[0060] The specific structures of the first nursing module 410 , the second nursing module 420 and the third nursing module 430 are introduced below respectively.

[0061] like Figure 4 and Figure 5 As shown, Figure 4 and Figure 5 is a schematic diagram of the internal structure of the first nursing module 410, which can be seen from Figure 4 As can be seen in the figure, the first care module 410 includes a first shell 411 and a plurality of knife net assemblies 412 connected to the first shell 411, each knife net assembly 412 includes a knife net bracket 4121, a knife net 4122 and a knife head 413, the knife head 413 is fully or partially arranged in the knife net bracket 4121 and connected to the knife net 4122, the knife net 4122 is inserted in the knife net bracket 4121 and covered on the knife head 413; the knife head 413 is transmission-connected to the transmission assembly 406, and under the drive of the drive motor 310, the transmission assembly 406 can drive the knife head 413 to rotate around its own central axis, so that the knife head 413 is constructed as the first care element 401, so that the hair extending into the knife net 4122 can be shaved by utilizing the shearing principle; the knife net 4122 is electrically connected to the second conductive element 405, so that the knife net 4122 can generate heat or generate microcurrent.

[0062] Preferably, if Figure 6As shown, the knife net bracket 4121 is tilted relative to the outer side of the first shell 411 and can be rotatably connected to the first shell 411. At the same time, the knife net bracket 4121 is also connected to the first shell 411 through an elastic element 4123 such as a spring, so that the knife net assembly 412 can rotate at an angle relative to the first shell 411 under the action of an external force. The elastic element 4123 can be stretched when the overall rotation of the knife net assembly 412 is limited by the first shell 411 and stops, thereby providing a way to reset the knife net assembly 412. Elastic force; more preferably, the knife net 4122 is movably inserted into the knife net bracket 4121 and protrudes from the outer surface of the knife net bracket 4121, so that when the knife net 4122 contacts the skin, the skin first contacts the knife net 4122, and the knife net 4122 and the knife head 413 are able to move a distance from the outside of the first shell 411 to the inside of the first shell 411 under the action of the contact force of the skin, and then are limited and cannot move, and then the knife net assembly 412 as a whole rotates at an angle relative to the first shell 411. At the same time, a knife net positioning frame 4125 is detachably provided in the first shell 411, and a knife net spring piece 4126 connected to the knife net 4122 is clamped on the knife net positioning frame 4125. The knife net spring piece 4126 has a certain elasticity and is configured to generate an elastic force that can reset the knife net 4122 when the knife net 4122 moves relative to the knife net bracket 4121. In this way, when the knife net 4122 contacts the skin, the knife net 4122 and the knife head 413 can move together in the direction from the outside of the first shell 411 toward the inside of the first shell 411. When the knife net 4122 separates from the skin, the knife net 4122 and the knife head 413 can be reset together under the elastic force provided by the knife net spring 4126.

[0063] In this way, through the above-mentioned arrangement, the knife net 4122 and the skin are in flexible contact, the knife net 4122 can move relative to the knife net bracket 4121, and the knife net bracket 4121 can also rotate relative to the shell. Compared with the traditional implementation mode in which the knife net bracket 4121 cannot move, the knife net 4122 can only move relative to the knife net bracket 4121, or the knife net bracket 4121 can only rotate relative to the shell, the knife net 4122 can better fit the skin, so that the knife head 413 can fully shave the beard or hair, and truly contact the skin without dead angles, avoiding the situation that the knife net 4122 does not fully contact the skin and thus shaves incompletely; or easily scratches the skin.

[0064] In an optional embodiment, in combination Figure 4 and Figure 5As shown, the transmission component 406 is a structure in which multiple gears are meshed. The transmission component 406 includes an input gear 4061 and multiple output gears 4062 meshed with the input gear 4061, each knife net component 412 is connected to a corresponding output gear 4062, the input gear 4061 is connected to an input shaft 4063, and each output gear 4062 is connected to an output shaft 4064. A connecting shaft spring 4065 is provided between the input shaft 4063 and the input gear 4061, and a connecting shaft spring 4065 is also provided between the output shaft 4064 and the output gear 4062, so that after the knife net 4122 contacts the skin, the knife net component 412 and the output shaft 4064 are in contact, in addition to the elastic force generated by the elastic element 4123 and the knife net spring 4126, the connecting shaft spring 4065 also generates a recoverable elastic deformation, thereby further increasing the flexibility of the contact between the knife net 4122 and the skin. Of course, the transmission assembly 406 may also be other types of transmission structures, which are not particularly limited here.

[0065] like Figure 7 As shown in the figure, in terms of the connection method between the knife net 4122 and the knife net spring piece 4126 and the structure of how to limit the knife net 4122, in an optional embodiment, the knife net bracket 4121 is provided with a stop structure 4121a at the end close to one end inside the first shell 411, and the stop structure 4121a is bent from the edge of the end of the knife net bracket 4121, so that the stop structure 4121a and the step inside the knife net bracket 4121 are located at the portion of the knife net bracket 4121 located inside the first shell 411. A limiting groove 4121b is formed, and a positioning block 4124 is provided in the limiting groove 4121b. The knife net 4122 and the knife net spring piece 4126 are both connected to the positioning block 4124; when the knife net 4122 moves relative to the knife net bracket 4121, the positioning block 4124 can move in the limiting groove 4121b, and the two opposite groove walls of the limiting groove 4121b are used to abut against the positioning block 4124 to limit the moving distance of the positioning block 4124 and make the knife net spring piece 4126 produce a recoverable deformation.

[0066] Furthermore, a positioning guide column 4121c is provided on the knife net bracket 4121, and the positioning block 4124 is provided with through holes passing through the opposite two ends thereof, and the positioning guide column 4121c is passed through the through holes, so that the positioning block 4124 is sleeved on the positioning guide column 4121c and can only move axially along the positioning guide shaft. Therefore, the positioning guide column 4121c can play a guiding role when the positioning block 4124 moves, preventing the positioning block 4124 from deviating from a predetermined trajectory when moving, so that the knife net 4122 will not deviate when it moves relative to the knife net bracket 4121.

[0067] In terms of the structure of the knife net positioning frame 4125, the knife net positioning frame 4125 includes a sleeve 4125a and a connecting ring 4125b connected to the sleeve 4125a, and the knife net spring piece 4126 is clamped on the connecting ring 4125b. The connecting ring 4125b is arranged opposite to the knife head 413, and is used for abutting against the knife head 413 when the knife net 4122 and the knife head 413 move relative to the knife net bracket 4121, thereby preventing the knife net 4122 and the knife head 413 from falling off.

[0068] See also Figure 7 and Figure 8 In one embodiment, the inner wall of the first shell 411 is provided with a plurality of buckles 4111 spaced apart along a circumferential direction, and all the buckles 4111 are passed through the sleeve 4125a and snapped onto the end surface of the sleeve 4125a, so that the opposite ends of the sleeve 4125a cannot move along their own axial direction under the limitation of the buckles 4111 and the inner wall of the first shell 411.

[0069] Alternatively, if Figure 8 As shown, one end of the sleeve 4125a is provided with a plurality of grooves 4125c, and the inner wall of the first shell 411 is provided with a plurality of protrusions 4112 correspondingly, and the protrusions 4112 are snapped into the grooves 4125c, thereby limiting the sleeve 4125a from rotating along the circumferential direction of the arrangement of the plurality of buckles 4111, thereby effectively preventing the knife net positioning frame 4125 from rotating due to the shaking of the knife net positioning frame 4125 during transportation or use of the multifunctional nursing device 10. Of course, the protrusions 4112 can also be provided at the end of the sleeve 4125a, and the grooves 4125c are provided on the inner wall of the first shell 411.

[0070] Preferably, the depth of the groove 4125c and the height of the protrusion 4112 are relatively small. When the cutter head 413 needs to be replaced or cleaned and the knife net positioning frame 4125 needs to be disassembled, it is only necessary to move the sleeve 4125a to rotate it around its own central axis. At this time, the protrusion 4112 is engaged in another groove 4125c. At this time, the connecting ring 4125b is deviated from the cutter head 413 (that is, it is not facing the cutter head 413), and the cutter head 413 can be taken out.

[0071] More preferably, if Figure 7 and Figure 8 As shown, the outer wall of the sleeve 4125a is provided with a first stopper 4125d, and the inner wall of the first housing 411 is provided with a second stopper 4113. The first stopper 4125d and the second stopper 4113 are used to abut against each other to limit the rotation angle of the sleeve 4125a along the circumferential direction. In this way, before replacing the cutter head 413, when the sleeve 4125a is rotated by a certain angle to make the connecting ring 4125b deviate from the cutter head 413, the sleeve 4125a can be further prevented from rotating further.

[0072] See also Fig. 9 In terms of the way in which the knife net 4122 is electrically connected to the second conductive element 405, each knife net 4122 is respectively connected to a corresponding knife net spring piece 4126, and two first conductive members 414 are arranged in the first shell 411, one end of each of the two first conductive members 414 is respectively abutted against a knife net spring piece 4126, and the other end is connected to the second conductive element 405; and the two first conductive members are respectively connected to the second conductive element 405 to serve as the two ends of the positive and negative poles, so that each first conductive member 414 can be connected to the knife net 4122 through a knife net spring piece 4126, thereby electrically connecting the second conductive element 405 to the knife net 4122.

[0073] Optionally, the number of knife net assemblies 412 can be two or more. When the number of knife net assemblies 412 is two, the knife net 4122 of one knife net assembly 412 is connected to one of the first conductive parts 414, and the knife net 4122 of the other knife net assembly 412 is connected to the other first conductive part 414.

[0074] When there are multiple knife net assemblies 412, the knife nets 4122 of the remaining knife net assemblies 412 are connected in series with one of the knife nets 4122 connected to the first conductive piece 414; or the knife nets 4122 of a part of the knife net assemblies 412 are connected in series with one of the knife nets 4122 connected to the first conductive piece 414, and the knife nets 4122 of another part of the knife net assemblies 412 are connected in series with another knife net 4122 connected to the first conductive piece 414, so that at least two of the multiple knife nets 4122 can serve as the positive or negative pole that contacts with human skin and forms a conductive loop.

[0075] For example, combining Figure 5 , Fig. 9 and Fig.10 In the illustrated embodiment, there are three knife net assemblies 412, wherein the knife net 4122 of one knife net assembly 412 is connected in series with one of the other two knife nets 4122 connected to the first conductive member 414 through a conductive spring, so that two of the three knife nets 4122 are connected in series to serve as the positive or negative pole that contacts the human skin and forms a conductive loop.

[0076] For another example, when there are four knife net assemblies 412, the knife nets 4122 of two of the knife net assemblies 412 are connected in series with one of the knife nets connected to the first conductive piece 414 through a conductive spring, so that three of the four knife nets 4122 are connected in series with each other as the positive electrode or negative electrode that contacts the human skin and forms a conductive loop; or the knife net 4122 of one of the knife net assemblies 412 is connected in series with one of the knife nets 4122 connected to the first conductive piece 414 through a conductive spring, and the knife net 4122 of the other knife net assembly 412 is connected in series with another knife net connected to the first conductive piece 414 through a conductive spring, so that two of the four knife nets 4122 are connected in series with each other as the positive electrode that contacts the human skin and forms a conductive loop, and the remaining two are connected in series with each other as the negative electrode that contacts the human skin and forms a conductive loop.

[0077] Of course, the knife nets 4122 are not limited to being connected in series via conductive springs, but can also be connected in series via wires, which is not limited here.

[0078] More specifically, combined with Fig. 9 and Fig.10 As shown, the first conductive member 414 includes a conductive pin 4141 and a first conductive sheet 4142 similar to an M shape, the first conductive sheet 4142 is connected to the second conductive element 405 through a wire (the wire is not shown in the figure), one end of the conductive pin 4141 abuts against the knife net spring piece 4126, and the other end abuts against the first conductive sheet 4142. Exemplarily, the conductive pin 4141 can be a pogopin spring needle, and the structure of the pogopin spring needle is a prior art, which is not described in detail here; in this way, when the first care module 410 is installed on the driving module 300, and it is necessary to use the knife net 4122 to generate heat to achieve the function of heating the skin or generate microcurrent to achieve the function of microcurrent stimulating the skin, the current can pass through the second connection terminal 322, the second conductive element 405, the first conductive sheet 4142, the conductive pin 4141, the knife net spring piece 4126 in sequence to reach the knife net 4122, so that the knife net 4122 can heat the skin or perform microcurrent stimulation on the skin when it contacts the skin.

[0079] In addition, in order to facilitate the disassembly of the components in the first nursing module 410, please continue to refer to Figure 4The first shell 411 is designed as a detachable structure. Specifically, the first shell 411 includes an upper shell 411a, a lower shell 411b and a partition 411c. The upper shell 411a has an upper cavity, the lower shell 411b has a lower cavity, and the partition 411c separates the upper cavity and the lower cavity from each other; the knife net assembly 412 is partially located in the upper cavity, and the second care element 402 is arranged on the partition 411c and is also located in the upper cavity; at least part of the first conductive element 404 and at least part of the second conductive element 405 are located in the lower cavity; the transmission assembly 406 is inserted through the partition 411c, that is, part of the transmission assembly 406 is located in the upper cavity to connect the knife head 413, and the other part is located in the lower cavity to connect the adapter assembly. Magnets 4127 are respectively installed in the upper cavity and the lower cavity, so that the upper shell 411a and the lower shell 411b are magnetically connected to each other, so that it is convenient to disassemble and clean the internal parts while ensuring that the current can be conducted.

[0080] In this way, it can be seen that when the first care module 410 is installed on the driving module 300, the first care module 410 itself has multiple functions. While ensuring the effectiveness and practicality of the main function of shaving hair (such as shaving) and keeping the knife net 4122 floating, the first care module 410 also has the function of heating the skin or stimulating the skin with microcurrent, which is convenient for users to use and enhances the user experience.

[0081] It should be noted that the number of the blade mesh components 412 in the first care module 410 is not limited, and can be one or any number. Obviously, setting a plurality of blade mesh components 412 can have a better effect of shaving hair and beautifying the skin.

[0082] See also Fig.11 and Fig.12 , Fig.11 and Fig.12This is a schematic diagram of the internal structure of the second care module 420, which includes a second shell 421 and a circuit board 422 arranged in the second shell 421, and two metal rings 423 arranged along the radial direction of the second shell 421 are embedded in the second shell 421. A plurality of second care elements 402 are arranged in a gap formed by the two metal rings 423 on one side of the circuit board 422, and one side of the circuit board 422 is provided with two second conductive members 424 arranged along the radial direction of the second care element 403. The second conductive members 424 can also be conductive pins 4141, and can also be pogopin spring pins. One end of each second conductive member 424 abuts against a corresponding metal ring 423, and the other end is electrically connected to the second conductive element 405 through a wire (the wire is not shown in the figure), so that the two metal rings 423 are constructed as the positive and negative poles of the third care element 403. In this way, when the second care module 420 is installed on the driving module 300, and the metal ring 423 needs to be used to generate heat to achieve the function of heating the skin or generate microcurrent to achieve the function of microcurrent stimulating the skin, the current can pass through the second connecting terminal 322, the second conductive element 405, and the second conductive piece 424 in sequence to reach the metal ring 423, so that the metal ring 423 can heat the skin or stimulate the skin with microcurrent when it comes into contact with the skin.

[0083] Please continue reading Fig.13 , Fig.13 The third care module 430 is a cross-sectional view of the third care module 430, which includes a third shell 431, a massage head 432, and an electrode sheet 433. The structure of the third shell 431 is similar to that of the first shell 411 in the first care module 410, and is also a detachable structure, which will not be described in detail here. The second care element 402 is installed on the partition 411c of the third shell 431; and the other parts of the third care module 430 are similar to those of the first care module 410. For example, it also includes a transmission assembly 406 for connecting to the drive module 300. One end of the massage head 432 is transmission-connected to the transmission assembly 406, and the other end is exposed to the third shell 431. The drive module 300 can be connected to the third shell 431 through the third shell 431. The transmission assembly 406 drives the massage head 432 to rotate around its own central axis, so that the massage head 432 is constructed as the first care element 401, which can rub against the skin to achieve a massage effect; the electrode sheet 433 is arranged on the third shell 431, and is electrically connected to the two ends of the second conductive element 405 with the massage head 432 respectively, so that the massage head 432 and the electrode sheet 433 can also serve as mutually electrically conductive positive and negative poles to generate heat to heat the skin or generate microcurrent to stimulate the skin, thereby being constructed as the positive and negative poles of the third care element 403 respectively.

[0084] In the specific manner of electrically connecting the massage head 432 and the second conductive element 405, as shown in FIG. Fig.14As shown, the outer peripheral surface of the massage head 432 is slidably covered with a conductive ring 434, and the conductive ring 434 can be electrically connected to the second conductive element 405 through a wire (the wire connecting the conductive ring 434 and the second conductive element 405 is not shown in the figure), and the material of the massage head 432 is a conductive metal or plastic. In this way, when the massage head 432 rotates around its own central axis, it does not affect the mutual conductivity between the conductive ring 434 and the massage head 432.

[0085] In order to achieve a better massage effect, similar to the first care module 410, the third care module 430 includes a plurality of massage heads 432 arranged at intervals along the circumference of the third shell 431. At the same time, the massage head 432 serves as one of the positive and negative electrodes, and a conductive ring 434 is correspondingly slidably sleeved on the outer circumference of each massage head 432, and all the conductive rings 434 are connected in series with each other and connected to the second conductive element 405, so that all the massage heads 432 are also connected in series with each other.

[0086] Correspondingly, the electrode sheet 433 serves as the other electrode between the positive electrode and the negative electrode, and includes multiple care sheets 4331 and connecting sheets 4332. The care sheets 4331 are also arranged at intervals along the circumference of the third shell 431. All care sheets 4331 and all massage heads 432 are arranged alternately, and every two adjacent care sheets 4331 are connected in series via a connecting sheet 4332 with a circular arc sheet structure.

[0087] In this way, when the massage head 432 contacts the skin, the care sheet 4331 also contacts the skin at the same time. The massage head 432 and the care sheet 4331 can simultaneously generate heat to heat the skin for beauty treatment or simultaneously generate microcurrent to stimulate the skin for microcurrent.

[0088] In the specific connection structure between the electrode sheet 433 and the second conductive element 405 and the specific connection structure between the massage head 432 and the second conductive element 405, Fig.14 and Fig.15 As shown, two third conductive members 435 are provided in the third housing 431, one end of one of the third conductive members 435 abuts against the electrode sheet 433, and the other end is connected to one end of the second conductive element 405 through a wire ( Fig.14 and Fig.15 A wire connecting the third conductive member 435 and the second conductive element 405 is not shown, thereby achieving the connection between the electrode sheet 433 and the second conductive element 405.

[0089] Furthermore, as mentioned above, the plurality of massage heads 432 are connected in series, and a conductive ring 434 is sleeved on the outer circumference of each massage head 432. Fig.14It can be seen that two adjacent conductive rings 434 are connected to each other through a second conductive sheet 436 similar to the shape of "ji", and the remaining adjacent conductive rings 434 are connected to each other through wires. In order to enable multiple conductive rings 434 to be connected to the second conductive element 405, one end of another third conductive member 435 abuts against the second conductive sheet 436, and the other end is connected to the other end of the second conductive element 405 through a wire, thereby realizing the connection of all the massage heads 432 to the second conductive element 405. Similarly, the third conductive member 435 here can also be the same conductive pin 4141 as that of the first care module 410 and the second care module, that is, it can be a pogopin, which will not be elaborated here.

[0090] In this way, when the third care module 430 is installed on the drive module 300 and it is necessary to use the massage head 432 and the electrode sheet 433 to generate heat to realize the function of heating the skin or generate a microcurrent to realize the function of microcurrent stimulating the skin, the current is divided into two paths after passing through the second connection terminal 322 and the second conductive element 405 in sequence. One path of the current passes through the third conductive member 435 abutting against the second conductive sheet 436 and the conductive ring 434 and then reaches the massage head 432, and the other path of the current reaches the electrode sheet 433 after passing through the third conductive member 435 abutting against the electrode sheet 433, so that the electrode sheet 433 can heat the skin or perform microcurrent stimulation on the skin when contacting the skin.

[0091] It should be noted that the number of the massage heads 432 is not limited either. It is not difficult to understand that when there is only one massage head 432, the conductive ring 434 sleeved on the massage head 432 can be directly connected to the second conductive element 405 through a wire.

[0092] It can be seen from this that the multifunctional care device 10 provided by the present application can realize different skin beauty care functions by replacing different care modules 400. When the first care module 410 is installed, functions such as hair removal, light beauty, skin heating or microcurrent stimulation can be realized; when the second care module 420 is installed, functions such as light beauty, skin heating or microcurrent stimulation can be realized; and when the third care module 430 is installed, functions such as massage, light beauty, skin heating or microcurrent stimulation can be realized. Therefore, it can be used for multiple purposes and meet the usage requirements of different scenarios. The circuits for realizing skin heating and microcurrent stimulation functions are the same circuit. When it is necessary to switch different functions, it can be switched by replacing the care module 400 and through buttons, thus facilitating the use of users.

[0093] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0094] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
