[0044] An embodiment of the present application provides a shaving module for performing multiple beauty treatments on human skin, such as shaving, irradiating skin to promote blood circulation, heating skin, or performing micro-current stimulation, so as to achieve one machine with multiple functions and meet the use requirements of users in different use scenarios.

[0045] Referring toFigure 1 and Figure 2 , Figure 1 Fig. 1 shows a shaft side view of a shaving module 100 according to an embodiment of the present application, Figure 2 Fig. 2 shows an exploded view of the shaving module 100 according to the embodiment of the present application, the shaving module 100 according to an embodiment of the present application comprises a housing 110, a plurality of cutter head assemblies 120, a plurality of cutter screen assemblies 130 and an illumination assembly 140, wherein the housing 110 is provided with a partition plate 116, a first conductive element 150 and a second conductive element 160.

[0046] Specifically, each cutter head assembly 120 is arranged in the housing 110 and comprises a cutter head 121 and a transmission module 122, the transmission module 122 of each cutter head assembly 120 is drivingly connected to the corresponding cutter head 121, and each cutter screen assembly 130 is connected to the housing 110 and at least exposed to the housing 110, and comprises a cutter screen 131 connected to the cutter head 121; the transmission module 122 is arranged through the partition plate 116 and drivingly connected to the cutter head 121, which is used to be connected with a driving module to drive the cutter head 121 to rotate around the central axis of the cutter head 121, so that the hair or beard extending into the cutter screen 131 can be shaved by using the shearing principle.

[0047] The cutter screen 131 is electrically connected to the first conductive element 150, and the first conductive element 150 is also used to be connected with the driving module 400, under the driving of the driving module, the first conductive element 150 can be electrically conducted with the driving module 400, so that the cutter screen 131 can generate heat or generate a micro-current, when the cutter screen 131 is used to generate heat, the cutter screen 131 can heat the skin by using the RF (Radio Frequency) radio frequency technology, so as to heat the dermal tissue of the human skin, and promote the collagen to be full of elasticity and vitality to achieve the effect of beauty; when the cutter screen 131 is used to generate a micro-current, the third care element can stimulate the facial muscle contraction by using the EMS (Electrical Muscle Stimulation) technology, so as to achieve the function of slimming face.

[0048] The illumination component 140 is disposed on the partition 116 and electrically connected to the second conductive element 160. The second conductive element 160 is also used to connect to the drive module and is electrically conductive with the drive module. Exemplarily, the illumination component 140 includes a lampshade 141 and a plurality of LEDs 142 covered by the lampshade 141. When the illumination component 140, the second conductive element 160, and the drive module 400 are electrically connected, the LEDs 142 can emit light capable of caring for the skin (such as visible light of a specific wavelength) to irradiate the skin and promote blood circulation. For example, when the LEDs 142 emit red light with a wavelength of 633±10nm, it can inhibit inflammation by suppressing cyclooxygenase, while also promoting blood circulation, stimulating collagen regeneration, and reducing the formation of acne scars, making it suitable for acne-prone skin, sensitive skin, and aging skin. It can repair wounds and improve allergic reactions. Alternatively, when the LEDs 142 emit green light with a wavelength of 405-470nm, the green light can have anti-inflammatory, antibacterial, and soothing effects. It can also purify the skin and has a certain therapeutic effect on bruising and pain, making it suitable for acne-prone, oily, and sensitive skin.

[0049] More specifically, in the structure of the blade assembly 130, such as Figure 3 As shown, the blade mesh assembly 130 includes not only the blade mesh 131, but also a blade mesh support 132. The blade mesh support 132 is inclined relative to the outer side of the housing 110 and rotatably connected to the housing 110. The blade mesh support 132 is also connected to the housing 110 via an elastic element 133, such as a spring, so that the blade mesh assembly 130 can rotate relative to the housing 110 by an angle under the action of an external force. The elastic element 133 can be stretched when the rotation of the blade mesh assembly 130 is limited and stopped by the housing 110, thereby providing an elastic force to reset the blade mesh assembly 130.

[0050] Preferably, the blade mesh 131 is movably inserted into the blade mesh support 132 and protrudes from the outer surface of the blade mesh support 132, so that when the blade mesh 131 comes into contact with the skin, the skin contacts the blade mesh 131 first. Under the contact force of the skin, the blade mesh 131 and the blade head 121 can move a certain distance from the outside of the housing 110 towards the inside of the housing 110 and are then limited to a certain distance. Then, the blade mesh assembly 130 rotates at an angle relative to the housing 110. At the same time, a blade mesh positioning frame 135 is detachably provided inside the housing 110. A blade mesh spring piece 136 connected to the blade mesh 131 is engaged on the blade mesh positioning frame 135. The blade mesh spring piece 136 has a certain elasticity and is configured to generate an elastic force that can reset the blade mesh 131 when it moves relative to the blade mesh support 132. In this way, when the blade net 131 comes into contact with the skin, the blade net 131 and the blade head 121 can move together in the direction from the outside of the housing 110 to the inside of the housing 110. When the blade net 131 is separated from the skin, the blade net 131 and the blade head 121 can be reset together under the elastic force provided by the blade net spring 136.

[0051] Thus, by the above arrangement, the razor net 131 and the skin are in flexible contact, the razor net 131 can move relative to the razor net support 132, and the razor net support 132 can rotate relative to the housing 110. Compared with the traditional razor net support 132 that cannot move, or the razor net support 132 that can only rotate relative to the housing 110, the razor net 131 can better conform to the skin, so that the razor head 121 can fully shave the beard or hair, and truly achieve dead angle-free contact with the skin, avoiding incomplete shaving or easy skin injury due to insufficient contact between the razor net 131 and the skin.

[0052] In an optional embodiment, in combination with Figure 2 and Figure 4 It is shown that the transmission module 122 is a structure of multiple gear meshes, the transmission module 122 includes an input gear 1221 and multiple output gears 1222 meshed with the input gear 1221, each razor net assembly 130 is connected to a corresponding output gear 1222, the input gear 1221 is connected with an input shaft 1223, and each output gear 1222 is connected with an output shaft 1224. A connecting shaft spring 1225 is arranged between the input shaft 1223 and the input gear 1221, and a connecting shaft spring 1225 is also arranged between the output shaft 1224 and the output gear 1222, so that after the razor net 131 contacts the skin, the razor net assembly 130 abuts against the output shaft 1224. In addition to the elastic force generated by the elastic element 133 and the razor net spring plate 136, the connecting shaft spring 1225 also generates a recoverable elastic deformation, thus further increasing the flexibility of the contact between the razor net 131 and the skin. Of course, the transmission module 122 can also be other types of transmission structures, which are not particularly limited here.

[0053] As shown in Figure 5 , in the connection mode of the razor net 131 and the razor net spring plate 136 and the structure for limiting the razor net 131, in an optional embodiment, the razor net support 132 is provided with a stop structure 1321 at the end portion close to the inner end of the housing 110. The stop structure 1321 is bent from the edge of the end portion of the razor net support 132, so that the stop structure 1321 and the step in the razor net support 132 form a limiting groove 1322 in the part of the razor net support 132 located in the housing 110. A positioning block 134 is arranged in the limiting groove 1322, and the razor net 131 and the razor net spring plate 136 are both connected to the positioning block 134. When the razor net 131 moves relative to the razor net support 132, the positioning block 134 can move in the limiting groove 1322, and the opposite groove walls of the limiting groove 1322 are used to abut against the positioning block 134 to limit the movement distance of the positioning block 134, and make the razor net spring plate 136 generate a recoverable deformation.

[0054] Further, the cutter net support 132 is provided with a positioning guide column 1323, and the positioning block 134 is provided with a through hole penetrating through opposite ends thereof, the positioning guide column 1323 is arranged in the through hole, so that the positioning block 134 is sleeved on the positioning guide column 1323 and can only move along the axial direction of the positioning guide column 1323, thus the positioning guide column 1323 can play a guiding role when the positioning block 134 moves, so as to avoid the positioning block 134 deviating from the predetermined track when moving, thereby preventing the cutter net 131 from deviating when moving relative to the cutter net support 132.

[0055] In the structure of the cutter net positioning frame 135, the cutter net positioning frame 135 comprises a sleeve 1351 and a connecting ring 1352 connected to the sleeve 1351, and the cutter net spring piece 136 is clamped to the connecting ring 1352, and the connecting ring 1352 is arranged opposite to the cutter head 121, which is used to abut against the cutter head 121 when the cutter net 131 and the cutter head 121 move relative to the cutter net support 132, so as to prevent the cutter net 131 and the cutter head 121 from falling off.

[0056] Referring to Figure 5 and Figure 6 In an embodiment, the inner wall of the shell 110 is provided with a plurality of buckles 111 arranged at intervals along a circumferential direction, and all the buckles 111 are arranged in the sleeve 1351 and clamped to the end face of the sleeve 1351, so that the opposite ends of the sleeve 1351 cannot move along the axial direction thereof under the limiting of the buckles 111 and the inner wall of the shell 110.

[0057] Alternatively, as Figure 6 shown, one end of the sleeve 1351 is provided with a plurality of grooves 1353, and the inner wall of the shell 110 is correspondingly provided with a plurality of protrusions 112, and the protrusions 112 are clamped in the grooves 1353, so as to limit the rotation of the sleeve 1351 along the circumferential direction of the above-mentioned plurality of buckles 111, thereby effectively preventing the beauty device from rotating due to the shaking of the cutter net positioning frame 135 during transportation or use. Of course, the protrusions 112 can also be arranged at the end of the sleeve 1351, and the grooves 1353 are arranged in the inner wall of the shell 110.

[0058] Preferably, the depth of the groove 1353 and the height of the protrusion 112 are relatively small, when the cutter head 121 needs to be replaced or cleaned and the cutter net positioning frame 135 needs to be disassembled, the sleeve 1351 only needs to be rotated around the central axis thereof, at this time the protrusion 112 is clamped in another groove 1353, at this time the connecting ring 1352 deviates from the cutter head 121 (i.e. not opposite to the cutter head 121), and the cutter head 121 can be taken out.

[0059] Preferably, the outer sidewall of the sleeve 1351 is provided with a first limiting block 1354, and the inner wall of the shell 110 is provided with a second limiting block 113, the first limiting block 1354 and the second limiting block 113 are used to abut each other to limit the rotation angle of the sleeve 1351 in the above-mentioned circumferential direction. In this way, when the sleeve 1351 is rotated by a certain angle to make the connecting ring 1352 deviate from the tool bit 121 before replacing the tool bit 121, the sleeve 1351 can also be prevented from continuing to rotate.

[0060] Referring to Figure 7 and Figure 8 , in the manner of electrical connection between the knife net 131 and the first conductive element 150, each knife net 131 is respectively connected with a knife net spring 136, and the shell 110 is provided with two conduction assemblies 170, one end of each conduction assembly 170 of the two conduction assemblies 170 respectively abuts against one knife net spring 136, and the other end is respectively connected to the first conductive element 150 to serve as the two ends of the positive and negative poles, so that each conduction assembly 170 can be connected with the knife net 131 through one knife net spring 136, and the first conductive element 150 is electrically connected with the knife net 131.

[0061] Alternatively, the number of knife net assemblies 130 can be two or more. When the number of knife net assemblies 130 is two, the knife net 131 of one of the knife net assemblies 130 is connected with one of the conduction assemblies 170, and the knife net 131 of the other knife net assembly 130 is connected with the other conduction assembly 170.

[0062] When the number of knife net assemblies 130 is more than two, the knife nets 131 of the remaining knife net assemblies 130 are connected in series with the knife nets 131 connected to the conduction assemblies 170; or the knife nets 131 of a part of the remaining knife net assemblies 130 are connected in series with the knife nets 131 connected to the conduction assemblies 170, and the knife nets 131 of another part of the remaining knife net assemblies 130 are connected in series with the knife nets 131 connected to the conduction assemblies 170, so that at least two of the at least multiple knife nets 131 can serve as the positive or negative pole of the conductive loop in contact with the human skin.

[0063] For example, in the embodiments shown in Figure 4 , Figure 7 and Figure 8 , the number of knife net assemblies 130 is three, the knife net 131 of one of the knife net assemblies 130 is connected in series with one of the other two knife nets 131 connected to the conduction assemblies 170 through a conductive spring, so that two of the three knife nets 131 are connected in series as the positive or negative pole of the conductive loop in contact with the human skin.

[0064] For example, when the razor net assembly 130 has four, two of the razor net assemblies 130 have their razor nets 131 connected to each other in series through the conductive spring, and the other two of the razor net assemblies 130 have their razor nets 131 connected to each other in series through the conductive spring, so that three of the four razor nets 131 are connected to each other in series as the positive electrode or the negative electrode which contacts the human skin and forms the conductive loop; or one of the razor net assemblies 130 has its razor net 131 connected to one of the razor nets 131 connected to the conductive spring of the conductive assembly 170 through the conductive spring, and the other of the razor net assemblies 130 has its razor net 131 connected to the other of the razor nets 131 connected to the conductive spring of the conductive assembly 170 through the conductive spring, so that two of the four razor nets 131 are connected to each other in series as the positive electrode which contacts the human skin and forms the conductive loop, and the other two of the four razor nets 131 are connected to each other in series as the negative electrode which contacts the human skin and forms the conductive loop.
