Description

Technical Field

[0001] This application relates to the technical field of care devices, and particularly to multifunctional care devices.

Background Art

[0002] In today's society, people's communication is expanding more and more, and various social activities are also increasing day by day. Therefore, more and more people are beginning to pay attention to their appearance. Along with the continuous development of the economy and the progress of science and technology, care devices (such as massagers, beard trimmers, etc.) that bring beauty effects to people's skin are also emerging one after another.

[0003] However, conventional 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, so the function of the care device product is single. With the progress of society, such care devices cannot meet people's usage needs. When there are different beauty needs, it is necessary to replace different types of care devices, which is not only troublesome to operate but also increases the user's expenses.

[0018] To make the above-mentioned objectives, features, and advantages of the present application clearer and easier to understand, specific embodiments of the present application will be described below in detail with reference to the accompanying drawings. The following description will include many specific details in order to provide a complete understanding of the present application. However, the present application can be implemented in many other forms different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application; therefore, the present application is not limited by the specific embodiments disclosed below.

[0019] In the description of this application, directions or positional relationships indicated by terms such as "center," "vertical direction," "horizontal direction," "length," "width," "thickness," "top," "bottom," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," "outside," "clockwise," "counterclockwise," "axial direction," "radial direction," and "circumferential direction" are the directions or positional relationships shown in the drawings and are used solely to facilitate or simplify the explanation of this application. It should be understood that these terms do not necessarily indicate or imply that the shown device or component has a specific direction, or a specific directional structure and operation, and therefore should not be interpreted as limiting this application.

[0020] Furthermore, the terms “first” and “second” are used solely for descriptive purposes and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features described. Thus, features limited to “first” and “second” may explicitly or implicitly include at least one such feature. In the description of this application, unless otherwise clearly and specifically limited, the term “plural” means at least two, for example, two, three, etc.

[0021] In the present invention, unless otherwise specifically defined and limited, terms such as "attachment," "connection," "bonding," and "fixing" should be understood in a broad sense. For example, these may be fixed connections, detachable connections, integral connections, mechanical connections, electrical connections, direct connections, indirect connections via an intermediate medium, internal communication between two members, or interaction relationships between two members.

The terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent a single embodiment.

[0024] This invention provides a multi-functional care device for performing various cosmetic procedures on human skin. For example, it can be used for multiple purposes with a single device, such as shaving hair, irradiating the skin to improve blood circulation, improving acne while touching the skin, or promoting skin metabolism. This eliminates the need to change care devices and can meet the needs of users in different usage scenarios.

[0025] Referring to Figures 1 and 2, Figure 1 shows a schematic diagram of a multifunctional care device 10 according to one embodiment of the present invention, and Figure 2 shows an exploded view of the multifunctional care device 10. The multifunctional care device 10 according to one embodiment of the present invention includes a main body 100, a control module 200, a drive module 300, and several care modules 400. The control module 200 is communicated to the drive module 300, and any of the care modules 400 are detachably connected to the drive module 300, so that different care modules 400 can be interchanged with each other. The control module 200 controls the operation of the drive module 300, and when different care modules 400 are attached to the drive module 300, the different care modules 400 are driven by the drive module 300 to realize different beauty functions.

[0026] Specifically, as shown in 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 which supplies power to the main control system 220, the main control system 220 which may be, for example, a PCB board, and provides control signals to control and operate the drive module 300, the drive module 300 includes a drive motor 310 and an adapter assembly 320, the drive motor 310 which provides power or an electrical signal, and the adapter assembly 320 which transmits the power or electrical signal provided by the drive motor 310 to the care module 400, thereby enabling different care modules 400 to realize different specific functions.

[0027] In some embodiments, as shown in Figure 1, at least one care module 400 includes a first care element 401, and any care module 400 includes a second care element 402, wherein the first care element 401 is rotatable around its central axis and shaves hair or massages the skin, and the adapter assembly 320 can convert the power provided by the drive motor 310 into an appropriate rotational speed to operate the first care element 401 properly, and the second care element 402 performs the function of irradiating the skin and improving blood circulation in the skin by emitting skin-care light (e.g., visible light of a specific wavelength), in which case the adapter assembly 320 transmits an electrical signal provided by the drive motor 310 to the second care element 402, thereby enabling the second care element 402 to 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 suppress inflammation by inhibiting cyclooxygenase, improve blood circulation, promote collagen regeneration, and reduce acne scars. It is suitable for acne-prone, sensitive, and aging skin, can repair wounds, and improve allergic reactions. Alternatively, when the control module 200 controls the second care element 402 to emit green light with a wavelength of 405-470nm, the green light has bactericidal, anti-inflammatory, and soothing effects. Furthermore, it can purify the skin, has a certain therapeutic effect on both congestion and pain, and is suitable for acne-prone, oily, and sensitive skin.

[0028] Furthermore, at least one care module 400 further includes a third care element 403 which generates heat or a microcurrent. When the third care element 403 generates heat, it can use RF (Radio Frequency) technology to heat the skin and the dermal tissue of human skin, thereby making collagen more elastic and achieving a cosmetic effect. When the third care element 403 generates a microcurrent, it can use EMS (Electrical Muscle Stimulation) technology to contract the facial muscles and achieve a face-slimming cosmetic function.

[0029] As shown in Figure 3, in one embodiment, when the care module 400 includes a second care element 402 and a third care element 403, the care 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 connected to the second care element 402 and the third care element 403, respectively. Accordingly, the adapter assembly 320 is provided with a first connection terminal 321 and a second connection terminal 322, and the drive motor 310 is provided with a third conductive element 311 and a fourth conductive element 312. The first connection terminal 321 has one end connected to the first conductive element 404 and the other end connected to the third conductive element 311, and the second connection terminal 322 has one end connected to the second conductive element 405 and the other end connected to the fourth conductive element 312. As a result, an electrical connection is achieved between the drive module 300 and the second care element 402 and the third care element 403. Furthermore, the control module 200 can control the drive module 300 to achieve electrical conductivity with the second care element 402 and the third care element 403, respectively.

[0030] Furthermore, if the care module 400 further includes a first care element 401, a transmission assembly 406 is connected to the first care element 401, and the drive motor 310 is provided with an adapter sleeve 313 that penetrates the adapter assembly 320, with one end of the adapter sleeve 313 connected to the transmission assembly 406 and the other end connected to the output terminal of the drive motor 310, and the control module 200 can control the drive motor 310 to drive the transmission assembly 406 to rotate the first care element 401 around its central axis.

[0031] For example, 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, and are not specifically limited.

[0032] Furthermore, functions such as shaving hair, massaging, using light irradiation for beauty treatments, heating the skin, and stimulating the skin with microcurrents can be freely combined, thereby giving different care modules 400 different beauty functions. Also, if the care module 400 includes only the second care element 402, the care module 400 will only have the first conductive element 404, the adapter assembly 320 will only have the first connection terminal 321, and the drive motor 310 will only have the third conductive element 311. In other words, the care module 400 will not have the second conductive element 405 and the transmission assembly 406, the adapter assembly 320 will not have the adapter sleeve 313 and the second connection terminal 322, and the drive motor 310 will not have the fourth conductive element 312, which will not be explained here.

[0033] In a preferred embodiment, to make it easier for the user to determine whether a care module 400 has been replaced when it is necessary to replace a different care module 400, the second care element 402 in the different care module 400 can output different electrical signals, such as different current or voltage values, resistance values, etc. The control module 200 is provided with an electrical signal detector, and after the care module 400 is replaced, the electrical signals passing through the different care module 400 will be different, so the control module 200 can identify the different care module 400 attached to the drive module 300 based on the different electrical signals output from 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 the different care module 400 is different, and after the care module 400 is replaced, the magnitude of the current passing through the LED lamp is different, and the magnitude of the output current can be detected by the electrical signal detector to determine that the care module 400 has been replaced.

[0034] As shown in Figure 1, the multifunctional care device 10 according to this embodiment has three care modules 400, which are defined as the first care module 410, the second care module 420, and the third care module 430. The first care module 410 and the second care module 420 each have a first care element 401, a second care element 402, and a third care element 403, while 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 for shaving hair, and the first care element 401 of the second care module 420 is for massaging the skin.

[0035] With the above setup, the multi-functional care device 10 can be used for multiple purposes with a single device, combining beauty functions such as shaving hair, massaging, applying beauty treatments with light irradiation, heating the skin, and stimulating the skin with microcurrents, thus meeting the needs of use in different situations. Furthermore, when any of the care modules 400 are connected to the drive module 300, the control module 200 can identify the different care modules 400 attached to the drive module 300, making it easier for the user to determine whether or not the care module 400 has been replaced, thus improving user convenience.

[0036] Furthermore, the circuits that realize the two functions of heating the skin and stimulating the skin with a microcurrent in the multi-functional care device 10 according to the above embodiment are the same circuit. When a user performs a specific operation, as shown in Figure 1, the main body 100 of the multi-functional care device 10 is provided with a first control button 101, a second control button 102, and a third control button 103 connected to a control module 200. The first control button 101 and the second control button 102 each output different electrical signals to the control module 200, controlling the third care element 403 to generate heat or a small current. For example, when the user presses the first control button 101, an electrical signal is output to the control module 200 that generates heat in the third care element 403. When the user presses the second control button 102, an electrical signal is output to the control module 200 that generates a small current in the third care element 403. The third control button 103 is an on / off button, and when the third control button 103 is pressed, the control module 200 starts operating, allowing the first care element 401 and the second care element 402 to operate. Of course, the control module 200 may also be provided with separate buttons to control and operate the first care element 401 and the second care element 402, respectively, and is not limited to the above.

[0037] The specific structures of the first care module 410, the second care module 420, and the third care module 430 are described below.

[0038] As shown in Figures 4 and 5, Figures 4 and 5 are schematic diagrams showing the internal structure of the first care module 410. As can be seen from Figure 4, the first care module 410 includes a first housing 411 and a plurality of mesh assemblies 412 connected to the first housing 411. Each mesh assembly 412 includes a mesh holder 4121, a mesh blade 4122, and an inner blade 413. All or part of the inner blade 413 is provided within the mesh holder 4121 and connected to the mesh blade 4122, and the mesh blade 4122 is inserted into the mesh holder 4121. The inner blade 413 is covered and is ductilely connected to the transmission assembly 406. Driven by the drive motor 310, the transmission assembly 406 can drive the inner blade 413 to rotate around its central axis, thereby configuring the inner blade 413 as the first care element 401. In this way, by the principle of shearing, it shaves hair that has entered the foil blade 4122. The foil blade 4122 is electrically connected to the second conductive element 405, thereby allowing the foil blade 4122 to generate heat or a small current.

[0039] Preferably, as shown in Figure 6, the mesh holder 4121 is mounted at an angle to the outside of the first housing 411 and is rotatably connected to the first housing 411, and at the same time the mesh holder 4121 is connected to the first housing 411 by an elastic element 4123, for example, a spring, so that the mesh assembly 412 can be rotated at a certain angle relative to the first housing 411 by an external force, and the elastic element 4123 can provide an elastic force to return the mesh assembly 412 to its original position because it is pulled when the rotation of the entire mesh assembly 412 is restricted in position and stopped by the first housing 411. More preferably, the foil blade 4122 is movably inserted into the foil blade holder 4121 and protrudes from the outer surface of the foil blade holder 4121, so that when the foil blade 4122 comes into contact with skin, the skin first comes into contact with the foil blade 4122, and the foil blade 4122 and the inner blade 413 move a certain distance along the direction from outside the first housing 411 toward the inside of the first housing 411 by the contact force of the skin, and after being restricted in position, they become unable to move, and thereafter the entire foil blade assembly 412 rotates at a certain angle relative to the first housing 411. Simultaneously, a mesh blade positioning frame 4125 is detachably provided within the first housing 411, and a mesh blade elastic sheet 4126 connected to the mesh blade 4122 is attached to the mesh blade positioning frame 4125. The mesh blade elastic sheet 4126 has a certain elasticity and is configured to generate an elastic force that returns the mesh blade 4122 to its original position when the mesh blade 4122 moves relative to the mesh blade holder 4121. In this way, when the mesh blade 4122 comes into contact with the skin, the mesh blade 4122 can move along the direction from outside the first housing 411 to inside the first housing 411 together with the inner blade 413, and when the mesh blade 4122 moves away from the skin, the mesh blade 4122 can return to its original position together with the inner blade 413 by the elastic force provided by the mesh blade elastic sheet 4126.

[0040] Thus, with the above setup, the foil blade 4122 makes soft contact with the skin, and not only does the foil blade 4122 move relative to the foil blade holder 4121, but the foil blade holder 4121 can also rotate relative to the housing. Compared to conventional embodiments where the foil blade holder 4121 cannot move and the foil blade 4122 can only move relative to the foil blade holder 4121, or where the foil blade holder 4121 can only rotate relative to the housing, the foil blade 4122 fits better to the skin, and as a result the inner blade 413 can shave the beard or hair sufficiently, making true contact with the skin without any blind spots, and avoiding missed spots or skin irritation caused by the foil blade 4122 not making sufficient contact with the skin.

[0041] In a preferred embodiment, as shown in Figures 4 and 5, the transmission assembly 406 has a structure in which multiple gears mesh, and the transmission assembly 406 includes an input gear 4061 and multiple output gears 4062 that mesh with the input gear 4061, each mesh assembly 412 is connected to a corresponding output gear 4062, the input gear 4061 is connected to a single input shaft 4063, and each output gear 4062 is connected to a single output shaft 4064 and input shaft 4063 A connecting shaft spring 4065 is provided between the input gear 4061 and the output shaft 4064 and the output gear 4062. As a result, after the mesh blade 4122 contacts the skin, the mesh blade assembly 412 contacts the output shaft 4064, generating elastic force in the elastic element 4123 and the mesh blade elastic sheet 4126. Additionally, a restorable elastic deformation occurs in the connecting shaft spring 4065, further improving the softness of the contact between the mesh blade 4122 and the skin. Of course, the transmission assembly 406 may be of other types and is not particularly limited here.

[0042] As shown in Figure 7, regarding the connection method between the mesh blade 4122 and the mesh blade elastic sheet 4126, and the structure for restricting the position of the mesh blade 4122, in a preferred embodiment, a stopper structure 4121a is provided at one end of the mesh blade holder 4121 that is close to the inside of the first housing 411, and the stopper structure 4121a is bent by the edge of the mesh blade holder 4121, thereby the stopper structure 4121a and the step difference inside the mesh blade holder 4121 are separated by a position restriction groove 4 in the portion of the mesh blade holder 4121 located inside the first housing 411. A 121b is formed, and a positioning block 4124 is provided within the position limiting groove 4121b. Both the mesh blade 4122 and the mesh blade elastic sheet 4126 are connected to the positioning block 4124. When the mesh blade 4122 moves relative to the mesh blade holder 4121, the positioning block 4124 can move within the position limiting groove 4121b. The two opposing groove walls of the position limiting groove 4121b come into contact with the positioning block 4124, limiting the distance the positioning block 4124 can move and causing a restorable deformation in the mesh blade elastic sheet 4126.

[0043] Furthermore, the mesh blade holder 4121 is provided with a positioning guide column 4121c, and the positioning block 4124 is provided with through holes that penetrate both of its opposing ends, and the positioning guide column 4121c is provided passing through the through holes, and the positioning block 4124 is fitted onto the positioning guide column 4121c and is movable only in the axial direction of the positioning guide axis, so the positioning guide column 4121c acts as a guide when the positioning block 4124 moves, preventing the positioning block 4124 from deviating from a predetermined trajectory when it moves, and thereby preventing the mesh blade 4122 from shifting when it moves relative to the mesh blade holder 4121.

[0044] Regarding the structure of the mesh blade positioning frame 4125, the mesh blade positioning frame 4125 includes a sleeve 4125a and a connecting ring 4125b connected to the sleeve 4125a. The mesh blade elastic sheet 4126 is engaged with the connecting ring 4125b, which is positioned directly opposite the inner blade 413. The connecting ring 4125b contacts the inner blade 413 when the mesh blade 4122 and the inner blade 413 move relative to the mesh blade holder 4121, thereby preventing the mesh blade 4122 and the inner blade 413 from falling off.

[0045] As shown in Figures 7 and 8, in one embodiment, the inner wall of the first housing 411 is provided with a plurality of snap fits 4111 spaced apart along the circumferential direction, all of which are provided through the sleeve 4125a and engage with the end face of the sleeve 4125a, so that the opposing ends of the sleeve 4125a cannot move along their axial direction due to the positional constraints of the snap fits 4111 and the inner wall of the first housing 411.

[0046] Preferably, as shown in Figure 8, a plurality of grooves 4125c are formed at one end of the sleeve 4125a, and a plurality of corresponding protrusions 4112 are provided on the inner wall of the first housing 411, with the protrusions 4112 engaging with the grooves 4125c, thereby restricting the sleeve 4125a from rotating along the circumferential direction in which the plurality of snap fits 4111 are arranged. This effectively prevents the mesh blade positioning frame 4125 from rotating due to shaking during transport or use of the multifunctional care device 10. Of course, the protrusions 4112 may be provided at the end of the sleeve 4125a, and the grooves 4125c may be formed on the inner wall of the first housing 411.

[0047] Preferably, the depth of the groove 4125c and the height of the projection 4112 are both small, and when it is necessary to remove the mesh positioning frame 4125 to replace or clean the inner blade 413, the sleeve 4125a can be rotated around its own central axis, at which point the projection 4112 engages with another groove 4125c, the connecting ring 4125b and the inner blade 413 are misaligned (i.e., not directly facing the inner blade 413), and the inner blade 413 can be removed.

[0048] More preferably, as shown in Figures 7 and 8, a first position limiting block 4125d is provided on the outer wall of the sleeve 4125a, and a second position limiting block 4113 is provided on the inner wall of the first housing 411, so that the first position limiting block 4125d and the second position limiting block 4113 come into contact with each other and limit the rotation angle of the sleeve 4125a along the circumferential direction. In this way, when the sleeve 4125a is rotated by a certain angle to shift the connecting ring 4125b away from the inner blade 413 before replacing the inner blade 413, it is possible to further prevent the sleeve 4125a from continuing to rotate.

[0049] As shown in Figure 9, regarding the electrical connection method between the mesh blades 4122 and the second conductive element 405, one mesh elastic sheet 4126 is connected to each mesh blade 4122, two first conductive members 414 are provided in the first housing 411, one end of each first conductive member 414 abuts against one mesh elastic sheet 4126 and the other end is connected to the second conductive element 405, and the two first conductive members are connected to the positive and negative poles of the second conductive element 405, so that each first conductive member 414 is connected to the mesh blade 4122 by one mesh elastic sheet 4126, and furthermore, the second conductive element 405 is electrically connected to the mesh blade 4122.

[0050] Preferably, the number of foil assemblies 412 may be two or more. If there are two foil assemblies 412, the foil blades 4122 of one foil assembly 412 are connected to one first conductive member 414, and the foil blades 4122 of the other foil assembly 412 are connected to the other first conductive member 414.

[0051] If there are multiple mesh assemblies 412, the mesh blades 4122 of the remaining mesh assemblies 412 and one mesh blade 4122 connected to the first conductive member 414 are connected in series with each other, or the mesh blades 4122 of some of the remaining mesh assemblies 412 and one mesh blade 4122 connected to the first conductive member 414 are connected in series with each other, and the mesh blades 4122 of other mesh assemblies 412 and other mesh blades 4122 connected to the first conductive member 414 are connected in series with each other, so that at least two of the multiple mesh blades 4122 are used as positive or negative electrodes to contact human skin and form a conductive circuit.

[0052] For example, referring to the embodiments shown in Figures 5, 9, and 10, there are three mesh assemblies 412, and one of the mesh blades 4122 of one mesh assembly 412 and one of the other two mesh blades 4122 connected to the first conductive member 414 are connected in series with a conductive spring, so that two of the three mesh blades 4122 are connected in series with each other and become the positive or negative electrode that comes into contact with human skin and forms a conductive circuit.

[0053] As another example, if there are four mesh assemblies 412, the mesh blades 4122 of two mesh assemblies 412 and one mesh blade connected to the first conductive member 414 are all connected in series with conductive springs, so that three of the four mesh blades 4122 are connected in series with each other and form positive or negative electrodes that come into contact with human skin to form a conductive circuit. Alternatively, the mesh blade 4122 of one mesh assembly 412 and one mesh blade 4122 connected to the first conductive member 414 are connected in series with conductive springs, and the mesh blade 4122 of another mesh assembly 412 and another mesh blade connected to the first conductive member 414 are connected in series with conductive springs, so that two of the four mesh blades 4122 are connected in series with each other and form positive electrodes that come into contact with human skin to form a conductive circuit, and the remaining two are connected in series with each other and form negative electrodes that come into contact with human skin to form a conductive circuit.

[0054] Of course, the mesh blades 4122 are not limited to being connected in series by conductive springs, but may also be connected in series with conductors, and are not limited to the above configuration.

[0055] More specifically, as shown in Figures 9 and 10, 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 a second conductive element 405 (wire not shown) by a conductor, and one end of the conductive pin 4141 abuts against the mesh elastic sheet 4126 and the other end abuts against the first conductive sheet 4142. Exemplarily, the conductive pin 4141 may be, for example, a pogo pin, the structure of which is conventional and will not be explained here. Thus, when the first care module 410 is attached to the drive module 300 and it is necessary to realize a function of heating the skin by generating heat with the mesh blade 4122, or a function of stimulating the skin with a microcurrent by generating a microcurrent, the current can flow sequentially through the second connection terminal 322, the second conductive element 405, the first conductive sheet 4142, the conductive pin 4141, and the mesh blade elastic sheet 4126 to reach the mesh blade 4122, thereby allowing the mesh blade 4122 to heat the skin or stimulate the skin with a microcurrent when it comes into contact with the skin.

[0056] Furthermore, in order to easily remove each component in the first care module 410, the first housing 411 is designed as a detachable structure, as shown in Figure 4. Specifically, the first housing 411 includes an upper housing 411a, a lower housing 411b, and a partition plate 411c, the upper housing 411a having an upper chamber, the lower housing 411b having a lower chamber, the partition plate 411c separating the upper and lower chambers from each other, a portion of the mesh assembly 412 located in the upper chamber, the second care element 402 provided on the partition plate 411c and located in the upper chamber, at least a portion of the first conductive element 404 and at least a portion of the second conductive element 405 located in the lower chamber, and the transmission assembly 406 provided through the partition plate 411c, that is, a portion of the transmission assembly 406 located in the upper chamber and connected to the inner blade 413, and the other portion located in the lower chamber and connected to the adapter assembly. Even when magnets 4127 are attached to the upper and lower chambers respectively, thereby magnetically attracting the upper housing 411a and the lower housing 411b to each other, and thus ensuring that current can be conducted, it becomes easier to remove and clean the internal components.

[0057] Thus, when the first care module 410 is attached to the drive module 300, the first care module 410 itself has multiple functions, ensuring that the effectiveness and practicality of its primary function of shaving hair (e.g., beard shaving) remain unchanged, and while maintaining the ability of the foil blade 4122 to float, the first care module 410 also has the function of heating the skin or stimulating the skin with a microcurrent, making it user-friendly and improving the user experience.

[0058] Furthermore, the number of foil assemblies 412 in the first care module 410 is not limited and may be one or any number. Clearly, having multiple foil assemblies 412 provides better hair shaving and skin beautification effects.

[0059] Figures 11 and 12 are schematic diagrams showing the internal structure of the second care module 420. As shown in Figures 11 and 12, the second care module 420 includes a second housing 421 and a circuit board 422 provided inside the second housing 421. The second housing 421 is fitted with two metal rings 423 spaced apart along its radial direction, and the multiple second care elements 402 are arranged in the gap formed by the two metal rings 423 on one side of the circuit board 422. On one side of 422 are two second conductive members 424 spaced apart along its radial direction. The second conductive members 424 may be conductive pins 4141, or they may both be pogo pins. One end of each second conductive member 424 abuts against a corresponding metal ring 423, and the other end is electrically connected to a second conductive element 405 (wire not shown) by a conductor. Thus, the two metal rings 423 are configured as the positive and negative poles of a third care element 403. Thus, when the second care module 420 is attached to the drive module 300 and it is necessary to realize the function of heating the skin by generating heat with the metal ring 423, or the function of stimulating the skin with a microcurrent by generating a microcurrent, the current can flow sequentially through the second connection terminal 322, the second conductive element 405, and the second conductive member 424 to reach the metal ring 423, thereby allowing the metal ring 423 to heat the skin or stimulate the skin with a microcurrent when it comes into contact with the skin.

[0060] Figure 13 is a cross-sectional view of the third care module 430, which, as shown in Figure 13, includes a third housing 431, a massage head 432, and an electrode sheet 433. The structure of the third housing 431 is similar to that of the first housing 411 in the first care module 410 and may be detachable, which will not be described here. The second care element 402 is attached to the partition plate 411c of the third housing 431. Other parts of the third care module 430 are similar to those of the first care module 410, for example, further including a transmission assembly 406 for connection to the drive module 300. The massage head 432 has one end ductilely connected to the transmission assembly 406 and the other end exposed from the third housing 431. This allows the massage head 432 to be driven and rotated around its central axis, thereby configuring the massage head 432 as the first care element 401, performing a massage by friction with the skin. The electrode sheet 433 is provided in the third housing 431 and is electrically connected to both ends of the massage head 432 and the second conductive element 405, respectively. As a result, the massage head 432 and the electrode sheet 433 can act as the positive and negative electrodes of the third care element 403, generating heat to heat the skin or generating a microcurrent to stimulate the skin.

[0061] Regarding the specific method of electrically connecting the massage head 432 and the second conductive element 405, as shown in Figure 14, a conductive ring 434 is slidably fitted onto the outer circumferential surface of the massage head 432, and the conductive ring 434 may be electrically connected to the second conductive element 405 by a conductor (the conductor connecting the conductive ring 434 and the second conductive element 405 is not shown). 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 conductivity between the conductive ring 434 and the massage head 432.

[0062] To achieve a better massage effect, the third care module 430, like the first care module 410, includes a plurality of massage heads 432 spaced apart along the circumferential direction of the third housing 431. Simultaneously, the massage heads 432 function as either a positive or negative electrode, and a corresponding conductive ring 434 is slidably fitted to the outer circumferential surface of each massage head 432. All conductive rings 434 are connected in series with each other to the second conductive element 405, thereby connecting all massage heads 432 in series with each other.

[0063] Accordingly, the electrode sheet 433 functions as the other electrode of the positive and negative electrodes and includes a plurality of care sheets 4331 and connecting sheets 4332, the care sheets 4331 are also spaced apart along the circumferential direction of the third housing 431, all of the care sheets 4331 are alternately provided with all of the massage heads 432, and two adjacent care sheets 4331 are connected in series with each other by connecting sheets 4332 having an arc-shaped sheet structure.

[0064] In this way, when the massage head 432 comes into contact with the skin, the care sheet 4331 also comes into contact with the skin at the same time, and the massage head 432 and the care sheet 4331 simultaneously generate heat to heat the skin for beauty treatment, or simultaneously generate a microcurrent to stimulate the skin with a microcurrent.

[0065] 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, as shown in Figures 14 and 15, two third conductive members 435 are provided inside the third housing 431, one end of one third conductive member 435 abuts against the electrode sheet 433, and the other end is connected to one end of the second conductive element 405 by a conductor (the conductor connecting the third conductive member 435 and the second conductive element 405 is not shown in Figures 14 and 15), thereby achieving the connection between the electrode sheet 433 and the second conductive element 405.

[0066] Furthermore, as described above, the plurality of massage heads 43232 are connected in series with each other, and one conductive ring 434 is fitted on the outer peripheral surface of each massage head 432. As can be seen from FIG. 14, two adjacent conductive rings 434 among them are connected to each other by a second conductive sheet 436 similar to a "Ji" shape, and the remaining adjacent conductive rings 434 are connected to each other by a conducting wire. In order to connect all the conductive rings 434 to the second conductive element 405, another third conducting member 435 has one end abutting against the second conductive sheet 436 and the other end connected to the other end of the second conductive element 405 by a conducting wire, whereby the connection between all the massage heads 432 and the second conductive element 405 is realized. Similarly, the third conducting member 435 here may be the same conductive pin 4141 as that of the first care module 410 and the second care module, that is, a pogo pin, and the description thereof is omitted here.

[0067] In this way, when the third care module 430 is attached to the drive module 300 and it is necessary to realize the function of generating heat by the massage head 432 and the electrode sheet 433 to heat the skin, or the function of generating a weak current to stimulate the skin with the weak current, the current sequentially flows through the second connection terminal 322 and the second conductive element 405, and then is divided into two paths. One current flows through the third conducting member 435 abutting against the second conductive sheet 436 and the conductive ring 434 to reach the massage head 432, and the other current flows through the third conducting member 435 abutting against the electrode sheet 433 to reach the electrode sheet 433. Thereby, when the electrode sheet 433 contacts the skin, it can heat the skin or stimulate the skin with a weak current.

[0068] It should be noted that the number of the massage heads 432 is not limited either. When there is only one massage head 432, it is easily understood that the conductive ring 434 fitted on the massage head 432 may be directly connected to the second conductive element 405 by a conducting wire.

[0069] Thus, the multi-functional care device 10 according to the present invention can realize different skin beauty care functions by exchanging different care modules 400. When the first care module 410 is attached, it can realize functions such as shaving hair, beauty treatment with light irradiation, skin heating, and skin stimulation with microcurrent. When the second care module 420 is attached, it can realize functions such as beauty treatment with light irradiation, skin heating, and skin stimulation with microcurrent. When the third care module 430 is attached, it can realize functions such as massage, beauty treatment with light irradiation, skin heating, and skin stimulation with microcurrent. Therefore, one device can be used for multiple purposes and meet the needs of use in different scenes. The circuits that realize the functions of skin heating and skin stimulation with microcurrent are the same, and when it is necessary to switch between different functions, the care module 400 can be exchanged and switched by a button, making it easy for the user to use.

However, as long as these combinations of technical features are inconsistent, they should be considered to fall within the scope described herein.

Furthermore, a person skilled in the art may make various modifications and improvements as long as they do not deviate from the spirit of this application, and all such modifications and improvements fall within the scope of protection of this application.
