The terms "vertical", "horizontal", "above", "below", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0024] One embodiment of the present application provides a beard trimming module, which is for performing various beauty treatments on human skin. For example, it can shave beards, irradiate the skin to improve blood circulation, heat the skin, stimulate with microcurrents, etc., and can be used for multiple purposes with one device, achieving the purpose of meeting the user's usage needs in different usage scenarios.

[0025] Referring to FIGS. 1 and 2, FIG. 1 shows a perspective view of a beard trimming module 100 according to an embodiment of the present application, and FIG. 2 shows an exploded view of the beard trimming module 100 according to the embodiment. The beard trimming module 100 according to an embodiment of the present application includes a housing 110, a plurality of inner blade assemblies 120, a plurality of mesh blade assemblies 130, and a light irradiation assembly 140. A partition plate 116, a first conductive element 150, and a second conductive element 160 are provided in the housing 110.

[0026] Specifically, each inner blade assembly 120 is provided in the housing 110 and includes an inner blade 121 and a transmission module 122. The transmission module 122 of each inner blade assembly 120 is connected to the corresponding inner blade 121 in a transmissible manner. Each mesh blade assembly 130 is connected to the housing 110 and includes a mesh blade 131 that at least exposes from the housing 110 and is connected to the inner blade 121. The transmission module 122 is provided through the partition plate 116 and is connected to the inner blade 121 in a transmissible manner and is connected to a drive module to drive the inner blade 121 to rotate around its central axis, and can shave the beard or hair that enters the mesh blade 131 according to the shearing principle.

[0027] The mesh blade 131 is electrically connected to the first conductive element 150, and the first conductive element 150 is also connected to the drive module 400. When the drive module drives, the first conductive element 150 can be electrically connected to the drive module 400. As a result, the mesh blade 131 can generate heat or a microcurrent. When the mesh blade 131 generates heat, the mesh blade 131 uses RF (Radio Frequency) wireless frequency technology to heat the skin and can heat the dermal tissue of the human skin, and by making collagen elastic, the beauty effect can be achieved. When the mesh blade 131 generates a microcurrent, the mesh blade can use EMS (Electrical Muscle Stimulation) technology to contract the facial muscles and achieve the function of face slimming beauty.

[0028] The light irradiation assembly 140 is provided on the partition plate 116 and is electrically connected to the second conductive element 160. The second conductive element 160 is similarly connected to the drive module and can be electrically connected to the drive module. Exemplarily, the light irradiation assembly 140 includes a cover 141 and a plurality of LED lamps 142 covered by the cover 141. After the light irradiation assembly 140, the second conductive element 160, and the drive module 400 are electrically connected, the LED lamp 142 can emit light that can care for the skin (for example, visible light of a specific wavelength), irradiate the skin, and realize the function of improving blood circulation. For example, when the LED lamp 142 emits red light with a wavelength of 633±10nm, it can achieve the effect of suppressing inflammation by suppressing cyclooxygenase, improve blood circulation, promote the regeneration of collagen, and reduce acne scars, and is suitable for acne-prone skin, sensitive skin, and aging skin, can repair wounds, and improve allergic reactions. Or, when the LED lamp 142 emits green light with a wavelength of 405 - 470nm, the green light has bactericidal, anti-inflammatory, and sedative effects. Furthermore, it can purify the skin, has a certain therapeutic effect on both congestion and pain, and is suitable for acne-prone skin, oily skin, and sensitive skin.

[0029] More specifically, regarding the structure of the net blade assembly 130, as shown in FIG. 3, in addition to including the net blade 131, the net blade assembly 130 further includes a net blade holder 132. The net blade holder 132 is provided inclined with respect to the outside of the housing 110 and is rotatably connected to the housing 110. At the same time, the net blade holder 132 is connected to the housing 110 by an elastic element 133, for example, a spring. Thereby, the net blade assembly 130 can rotate at a certain angle with respect to the housing 110 by an external force. When the rotation of the entire net blade assembly 130 is restricted in position and stopped by the housing 110, the elastic element 133 is pulled, so that an elastic force for returning the net blade assembly 130 can be provided.

[0030] Preferably, the net blade 131 is movably inserted into the net blade holder 132 and protrudes from the outer surface of the net blade holder 132. Thereby, when the net blade 131 contacts the skin, the skin first contacts the net blade 131. The net blade 131 and the inner blade 121 move a certain distance along the direction from outside the housing 110 to inside the housing 110 by the contact force of the skin and are restricted in position, and then they cannot move. After that, the entire net blade assembly 130 rotates at a certain angle with respect to the housing 110. At the same time, a net blade positioning frame 135 is detachably provided in the housing 110, and a net blade elastic sheet 136 connected to the net blade 131 is engaged with the net blade positioning frame 135. The net blade elastic sheet 136 has a certain elasticity and is configured to generate an elastic force for returning the net blade 131 when the net blade 131 moves with respect to the net blade holder 132. In this way, when the net blade 131 contacts the skin, the net blade 131 can move along the direction from outside the housing 110 to inside the housing 110 together with the inner blade 121. When the net blade 131 leaves the skin, the net blade 131 can return together with the inner blade 121 by the elastic force provided by the net blade elastic sheet 136.

[0031] In this way, with the above installation, the net blade 131 contacts the skin softly. Not only can the net blade 131 move relative to the net blade holder 132, but also the net blade holder 132 can rotate relative to the housing 110. Compared with the conventional embodiment where the net blade holder 132 cannot move and the net blade 131 can only move relative to the net blade holder 132, or the net blade holder 132 can only rotate relative to the housing 110, the net blade 131 fits the skin better. As a result, the inner blade 121 can shave the beard or hair sufficiently, contact the skin without dead corners in the true sense, and avoid stubble or skin damage caused by insufficient contact between the net blade 131 and the skin.

[0032] In a preferred embodiment, as shown in FIGS. 2 and 4, the transmission module 122 has a structure in which a plurality of gears mesh with each other. The transmission module 122 includes an input gear 1221 and a plurality of output gears 1222 meshed with the input gear 1221. Each net blade assembly 130 is connected to a corresponding one of the output gears 1222. The input gear 1221 is connected to a single input shaft 1223, and each output gear 1222 is connected to a single output shaft 1224. A connecting shaft spring 1225 is provided between the input shaft 1223 and the input gear 1221, and a connecting shaft spring 1225 is also provided between the output shaft 1224 and the output gear 1222. Thereby, after the net blade 131 contacts the skin, the net blade assembly 130 abuts against the output shaft 1224, generating an elastic force on the elastic element 133 and the net blade elastic sheet 136, and a recoverable elastic deformation also occurs in the connecting shaft spring 1225, so that the softness of the contact between the net blade 131 and the skin can be further improved. Of course, the transmission module 122 may have other types of transmission structures, and is not particularly limited here.

[0033] As shown in FIG. 5, regarding the connection method between the mesh blade 131 and the mesh blade elastic sheet 136 and the structure for restricting the position of the mesh blade 131, in a preferred embodiment, at one end of the housing 110 of the mesh blade holder 132 near the inner side, a stopper structure 1321 is provided. The stopper structure 1321 is formed by being bent by the edge of the mesh blade holder 132. Thus, the stopper structure 1321 and the step inside the mesh blade holder 132 form a position restriction groove 1322 in the portion located inside the housing 110 of the mesh blade holder 132. A positioning block 134 is provided in the position restriction groove 1322. Both the mesh blade 131 and the mesh blade elastic sheet 136 are connected to the positioning block 134. When the mesh blade 131 moves relative to the mesh blade holder 132, the positioning block 134 can move within the position restriction groove 1322. The two opposing groove walls of the position restriction groove 1322 abut against the positioning block 134 to limit the moving distance of the positioning block 134 and cause a recoverable deformation in the mesh blade elastic sheet 136.

[0034] Furthermore, a positioning guide post 1323 is provided on the mesh blade holder 132. The positioning block 134 is provided with through holes penetrating both opposite ends of itself. The positioning guide post 1323 is provided by penetrating through the through holes. The positioning block 134 is externally fitted onto the positioning guide post 1323 and can only move in the axial direction of the positioning guide shaft. Therefore, the positioning guide post 1323 plays a guiding role when the positioning block 134 moves, avoiding the positioning block 134 deviating from a predetermined trajectory when it moves. Thereby, when the mesh blade 131 moves relative to the mesh blade holder 132, it also does not deviate.

[0035] Regarding the structure of the mesh blade positioning frame 135, the mesh blade positioning frame 135 includes a sleeve 1351 and a connection ring 1352 connected to the sleeve 1351. The mesh blade elastic sheet 136 is fastened to the connection ring 1352. The connection ring 1352 is provided facing the inner blade 121. When the mesh blade 131 and the inner blade 121 move relative to the mesh blade holder 132 and abut against the inner blade 121, the detachment of the mesh blade 131 and the inner blade 121 can be avoided.

[0036] As shown in FIGS. 5 and 6, in one embodiment, a plurality of snap fits 111 are provided on the inner wall of the housing 110 at intervals along the circumferential direction. All the snap fits 111 are provided through the sleeve 1351 and engaged with the end face of the sleeve 1351. Thereby, both opposite ends of the sleeve 1351 cannot move along its axial direction due to the position limitation of the snap fits 111 and the inner wall of the housing 110.

[0037] Optionally, as shown in FIG. 6, a plurality of concave grooves 1353 are formed at one end of the sleeve 1351, and a plurality of protrusions 112 are correspondingly provided on the inner wall of the housing 110. The protrusions 112 are engaged with the concave grooves 1353. Thereby, the rotation of the sleeve 1351 along the circumferential direction in which the plurality of snap fits 111 are arranged can be restricted. Therefore, during the transportation or use of the beauty device, it can be effectively prevented that the net blade positioning frame 135 rotates by shaking. Of course, the protrusions 112 may be provided at the end of the sleeve 1351, and the concave grooves 1353 are formed on the inner wall of the housing 110.

[0038] Preferably, both the depth of the concave groove 1353 and the height of the protrusion 112 are small. When it is necessary to remove the net blade positioning frame 135 to replace or clean the inner blade 121, the sleeve 1351 is rotated around its own central axis. At this time, the protrusion 112 is engaged with another concave groove 1353, and the connection ring 1352 and the inner blade 121 are displaced (that is, not facing the inner blade 121), and the inner blade 121 can be taken out.

[0039] More preferably, a first position limiting block 1354 is provided on the outer wall of the sleeve 1351, and a second position limiting block 113 is provided on the inner wall of the housing 110. The first position limiting block 1354 and the second position limiting block 113 are in contact with each other to limit the rotation angle of the sleeve 1351 along the circumferential direction. In this way, before replacing the inner blade 121, when the sleeve 1351 is rotated by a certain angle to shift the connection ring 1352 from the inner blade 121, it is possible to further prevent the sleeve 1351 from continuing to rotate.

[0040] As shown in FIGS. 7 and 8, regarding the electrical connection method between the mesh blade 131 and the first conductive element 150, one mesh blade elastic sheet 136 is correspondingly connected to each mesh blade 131. Two conduction members 170 are provided in the housing 110. One end of each conduction member 170 in the two conduction members 170 is in contact with one mesh blade elastic sheet 136 respectively, and the other end is connected to both ends of the positive and negative electrodes of the first conductive element 150 respectively. Thereby, each conduction member 170 is connected to the mesh blade 131 by one mesh blade elastic sheet 136, and further, the first conductive element 150 is electrically connected to the mesh blade 131.

[0041] Optionally, the number of the mesh blade assemblies 130 may be two or more. When the number of the mesh blade assemblies 130 is two, the mesh blade 131 of one mesh blade assembly 130 is connected to one conduction member 170, and the mesh blade 131 of the other mesh blade assembly 130 is connected to the other conduction member 170.

[0042] When there are multiple mesh blade assemblies 130, the mesh blades 131 of the remaining mesh blade assemblies 130 and one mesh blade 131 connected to the conduction member 170 are connected in series with each other, or the mesh blades 131 of some of the remaining mesh blade assemblies 130 and one mesh blade 131 connected to the conduction member 170 are connected in series with each other, and the mesh blades 131 of some other mesh blade assemblies 130 and the other mesh blade 131 connected to the conduction member 170 are connected in series with each other. As a result, at least two of the plurality of mesh blades 131 are used as the positive or negative electrode that contacts the human skin to form a conductive circuit.

[0043] For example, referring to the embodiments shown in FIGS. 4, 7, and 8, there are three mesh blade assemblies 130. One mesh blade 131 of one mesh blade assembly 130 and one of the other two mesh blades 131 connected to the conduction member 170 are connected in series with each other by a conductive spring. As a result, two of the three mesh blades 131 are connected in series with each other and used as the positive or negative electrode that contacts the human skin to form a conductive circuit.

[0044] As another example, when there are four mesh blade assemblies 130, the mesh blades 131 of two mesh blade assemblies 130 and one mesh blade connected to the conduction member 170 are all connected in series with each other by a conductive spring. As a result, three of the four mesh blades 131 are connected in series with each other and used as the positive or negative electrode that contacts the human skin to form a conductive circuit. Or, one mesh blade 131 of one mesh blade assembly 130 and one mesh blade 131 connected to the conduction member 170 are connected in series with each other by a conductive spring, and the mesh blades 131 of another mesh blade assembly 130 and another mesh blade connected to the conduction member 170 are connected in series with each other by a conductive spring. As a result, two of the four mesh blades 131 are connected in series with each other and used as the positive electrode that contacts the human skin to form a conductive circuit, and the remaining two are connected in series with each other and used as the negative electrode that contacts the human skin to form a conductive circuit.

[0045] Of course, the mesh blades 131 are not limited to being connected in series by a conductive spring, and they may be connected in series with each other by a conducting wire, which is not limited here.

[0046] More specifically, as shown in FIG. 8, the conduction member 170 includes a conductive pin 171 and a conductive sheet 172 similar to an M shape. The conductive sheet 172 is connected to the first conductive element 150 by a conducting wire. One end of the conductive pin 171 abuts against the net blade elastic sheet 136, and the other end abuts against the conductive sheet 172. Exemplarily, the conductive pin 171 may be a pogopin. Since the structure of the pogopin is a conventional technology, the description thereof is omitted here. In this way, when the whisker shaving module 100 is attached to the driving module 400 and it is necessary to realize the function of generating heat by the net blade 131 to heat the skin or generating a weak current to stimulate the skin with the weak current, the current can sequentially flow through the first connection terminal 421, the first conductive element 150, the conductive sheet 172, the conductive pin 171, and the net blade elastic sheet 136 to reach the net blade 131. Thereby, when the net blade 131 contacts the skin, it can heat the skin or stimulate the skin with a weak current.

[0047] In addition, in order to easily remove each component in the beard trimming module 100, as shown in FIG. 2, the housing 110 is designed to have a detachable structure. Specifically, the housing 110 includes an upper housing 114, a lower housing 115, and a partition plate 116. The upper housing 114 has an upper chamber, the lower housing 115 has a lower chamber, the partition plate 116 partitions the upper chamber and the lower chamber from each other. A part of the net blade assembly 130 is located in the upper chamber, the light irradiation assembly 140 is provided on the partition plate 116 and located in the upper chamber. At least a part of the first conductive element 150 and at least a part of the second conductive element 160 are located in the lower chamber. The transmission module 122 is provided through the partition plate 116, that is, a part of the transmission module 122 is located in the upper chamber and connected to the inner blade 121, and the other part is located in the lower chamber and connected to the drive module 400. Magnets 137 are respectively mounted in the upper chamber and the lower chamber, whereby the upper housing 114 and the lower housing 115 are magnetically attracted to each other, thereby facilitating the removal and cleaning of the internal components even when ensuring that the current can be conducted. Of course, the upper housing 114 and the lower housing 115 may be detachably connected to each other by other methods, which are not limited here.
