At the same time, the setting of the sealing member can enhance the airtightness between the cavity and the light-emitting component, prevent external air from entering the cavity to form condensed water, and avoid the refraction of the pulsed light emitted by the light-emitting component by the condensed water, which is beneficial to improving the light output effect of the hair removal device.

The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0022] In an example embodiment of this application, please refer to Figures 1 - 4 , Figure 1 is a three-dimensional example diagram of the hair remover in Embodiment 1 provided by the embodiment of this application; Figure 2 is an exploded view of the hair remover in Embodiment 1 provided by the embodiment of this application; Figure 3 is a cross-sectional view of the hair remover in Embodiment 1 provided by the embodiment of this application; Figure 4 is provided by the embodiment of this application Figure 3 An enlarged view at A.

[0023] As shown Figures 1 - 4 in the figure, a hair removal device includes a housing 1, a support member 2 disposed in the inner cavity of the housing 1, a light emitting assembly 3, a seal 8, a cold compress member 4, and at least one air guiding channel member 5; the support member 2 includes a support front cover 21 and a support rear cover 22. Please refer to Figure 7 , Figure 7 which Figure 5 is another exploded view of the structure shown in the figure. As shown Figure 7 in the figure, the front and rear end faces of the support front cover 21 are respectively provided with a first groove 211 and a second groove 212. The front end of the support rear cover 22 is inserted into the second groove 212 and covers the notch of the second groove 212. The bottom wall of the first groove 211 and the bottom wall of the second groove 212 are penetrated and communicated to form a through hole. At least one air outlet through hole is provided on the side wall of the second groove 212. The hole wall of the air outlet through hole extends outward from the second groove 212 to form an air guiding pipe; the light emitting assembly 3 is located in the space formed by enclosing the support rear cover 22 and the second groove 212 and covers the through hole. A part of the structure of the light emitting assembly 3 is clamped between the bottom wall of the second groove 212 and the support rear cover 22; the seal 8 is clamped between the bottom wall of the second groove 212 and the light emitting assembly 3; the cold compress member 4 is connected to the support front cover 21 and / or the housing 1 and covers the light outlet of the housing 1. The cold compress member 4, the light emitting assembly 3, and the support front cover 21 enclose a cavity 1201; the side wall of the first end of the air guiding channel member 5 includes a channel air inlet hole that cooperates with the air guiding pipe. When the first end of the air guiding channel member 5 is connected to the support front cover 21, the air guiding pipe is placed into the channel air inlet hole. The second end of the air guiding channel member 5 extends along the support front cover 21 towards the support rear cover 22 to the tail end of the housing 1 and abuts against the inner wall of the tail end of the housing 1. The rear end face of the air guiding channel member 5 includes a channel air outlet hole that communicates with the heat dissipation air outlet hole at the tail end of the housing 1.

[0024] In a specific example, the housing 1 of the hair removal device can be oval, gun-shaped or other shapes, and no further limitation is made here. The material of the housing 1 can be plastic, aluminum alloy, ceramic, etc., and no further limitation is made here either. The housing 1 is composed of an upper housing 11, a lower housing 12, and a front cover 13. The front cover 13 is sleeved on the front end of the combination of the upper housing 11 and the lower housing 12 to form the inner cavity of the housing 1. The front cover 13 is provided with a light outlet to enable the hair removal device to emit light smoothly. When the hair removal device is a wired hair removal device, the rear end of the hair removal device is connected to the connection line of the power adapter to achieve continuous high-power power supply.

[0025] The hair removal device further includes a support member 2, a light emitting assembly 3, a seal 8, a cold compress member 4, and at least one air guide channel member 5. The support member 2, the light emitting assembly 3, the seal 8, the cold compress member 4, and at least one air guide channel member 5 are disposed in the inner cavity of the housing 1. Among them, the support member 2 includes a support front cover 21 and a support rear cover 22. The surface of the support front cover 21 facing the light outlet of the housing 1 is the front end surface of the support front cover 21, and the surface of the support front cover 21 facing away from the light outlet is the rear end surface of the support front cover 21. A first groove 211 is formed in the front end surface of the support front cover 21, and a second groove 212 is formed in the rear end surface of the support front cover 21. The bottom wall of the first groove 211 and the bottom wall of the second groove 212 penetrate and communicate with each other to form a through hole. The front end of the support rear cover 22 is inserted into the second groove 212 and covers the notch of the second groove 212.

[0026] Among them, the side wall of the first end of the air guide channel member 5 includes a channel air inlet hole for cooperating with the air guide pipe. When the first end of the air guide channel member 5 is connected to the support front cover 21, the air guide pipe is placed into the channel air inlet hole, so that the inside of the air guide channel member 5 communicates with the space formed by the cooperation of the second groove 212 and the support rear cover 22, and it is avoided that the air in this space overflows from the connection between the channel air inlet hole and the air outlet through hole when entering the air guide channel member 5, improving the sealing performance. The second end of the air guide channel member 5 extends along the support front cover 21 towards the support rear cover 22 to the tail end of the housing 1 and abuts against the inner wall of the tail end of the housing 1. The second end of the air guide channel member 5 includes a channel air outlet hole communicating with the heat dissipation air outlet hole at the tail end of the housing 1 to discharge the air in the air guide channel member 5 out of the hair removal device, making the structure inside the hair removal device compact and ensuring the heat dissipation effect at the same time.

[0027] Part of the structure of the light emitting assembly 3 is clamped between the bottom wall of the second groove 212 and the support rear cover 22; the seal 8 is clamped between the bottom wall of the second groove 212 and the light emitting assembly 3. The cold compress member 4 is connected to the support front cover 21 and / or the housing 1 and covers the light outlet of the housing 1. The cold compress member 4, the light emitting assembly 3, and the support front cover 21 enclose a cavity 1201. During the use of the hair removal device, the pulsed light excited by the light emitting assembly 3 will pass through the cavity 1201 and finally be emitted to the outside of the hair removal device through the cold compress member 4. In this application, under the irradiation of the pulsed light, the air pressure in the cavity 1201 formed by the cold compress member 4, the light emitting assembly 3, and the support front cover 21 will decrease. In this way, the condensed water generated on the cold compress member 4 can be vaporized, thereby reducing the air density in the cavity 1201 and forming a vacuum-like environment, further avoiding the regeneration of condensed water on the cold compress member 4 and affecting the light output rate and light output effect. At the same time, the setting of the seal 8 can enhance the airtightness between the cavity 1201 and the light emitting assembly 3, prevent external air from entering the cavity 1201 to form condensed water, and avoid the condensed water refracting the pulsed light excited by the light emitting assembly 3, which is beneficial to improving the light output effect of the hair removal device.

[0028] Specifically, the material of the sealing member 8 can be rubber, plastic, graphite or metal.

[0029] Specifically, the cold compress 4 can be made of sapphire, ceramic or quartz, etc. When the cold compress 4 is sapphire, it can effectively reduce the heat on the side of the hair removal device that is in contact with the user when in use, increase the comfort of use, and improve the conduction efficiency of the light beam, thereby improving the hair removal effect.

[0030] For details, please combine Figures 5 - 7 , Figure 5 It is a schematic diagram of the assembly of part of the structure of the hair removal device in the first embodiment provided in the embodiment of the present application; Figure 6 for Figure 5 Exploded view of the structure shown.

[0031] Please refer to Figure 7 The sealing member 8 comprises a mounting groove, the notch of the mounting groove abuts against the bottom wall of the second groove 212 and is arranged around the through hole, and the bottom wall of the mounting groove is provided with a first light-emitting through hole 81; The light emitting component 3 includes: a filter 31, a high temperature resistant gasket 32, a light emitting member 33 and a reflector 34; the filter 31 is installed in the installation groove and is clamped between the bottom wall of the second groove 212 and the bottom wall of the installation groove; the high temperature resistant gasket 32 abuts against a side of the sealing member 8 away from the notch of the installation groove, and the high temperature resistant gasket 32 forms a second light emitting through hole 321 connected to the first light emitting through hole 81; the light emitting member 33 is installed in the space enclosed by the second groove 212 and the supporting back cover 22; the reflector 34 includes a reflective body 342 and a mounting portion 341, the reflective body 342 is arranged around the light emitting member 33 and is formed with an opening facing the through hole, the mounting portion 341 is bent and connected to the opposite sides of the reflective body 342, and is clamped between the high temperature resistant gasket 32 and the supporting back cover 22.

[0032] Specifically, the light emitting element 33 may be a lamp tube, which is used to generate laser or pulse light. A surrounding winding 331 may be provided on the outer periphery of the lamp tube, and the provision of the winding 331 is conducive to improving the light effect excited by the light emitting element 33 .

[0033] Specifically, the light reflector 34 is disposed around the light emitter 33 and forms an opening facing the light outlet. In this way, the light reflector 34 can reflect the light emitted by the light emitter 33, causing it to converge and emit in the direction of the light outlet, thereby improving the lighting effect. The material of the light reflector 34 can be aluminum alloy, stainless steel, or coated material, etc. Specifically, the light reflector 34 includes a light reflecting main body 342 and a mounting portion 341. At least part of the structure of the light reflecting main body 342 is an arc structure to surround the light emitter 33. The mounting portion 341 is connected to both sides of the light reflecting main body 342 where the opening is formed, and is bent and extended away from the opening to be clamped between the high-temperature resistant gasket 32 and the support rear cover 22.

[0034] Specifically, the filter 31 can filter out light of specific wavelengths, thereby ensuring that the hair removal device can act on hair follicles without damaging the user's skin. The material of the high-temperature resistant gasket 32 can be silicone, aluminum alloy, or ceramic, etc. Arranging the high-temperature resistant gasket 32 between the filter and the light emitter 33 can achieve heat insulation, preventing the heat energy of the reflector cup from being transferred to the filter and affecting the service life of the filter. The shapes of the filter 31 and the high-temperature resistant gasket 32 can be set according to the shape of the housing 1, and no further limitations are imposed here.

[0035] In specific implementation, the seal 8 includes a mounting groove. One end face of the mounting groove on the side of the groove opening abuts against the part of the bottom wall of the second groove 212 that does not form a through hole, so that the seal 8 is arranged around the through hole. The bottom wall of the mounting groove is provided with a first light outlet through hole 81, and the first light outlet through hole 81 is arranged opposite to the through hole. In this way, the pulsed light excited by the light emitter 33 can sequentially pass through the second light outlet through hole 321 and the first light outlet through hole 81, then pass through the filter 31, enter the cavity 1201 through the through hole, and then pass through the cold compress member 4 and be emitted outside the hair removal device.

[0036] It can be seen that in this example, the seal 8 and the filter 31, the high-temperature resistant gasket 32, the light emitter 33, and the light reflector 34 in the light outlet assembly 3 can be stacked and clamped between the support front cover 21 and the support rear cover 22. Thus, the installation and fixation of the light outlet assembly 3 can be achieved by connecting the support front cover 21 and the support rear cover 22, which is beneficial to improving the convenience of assembling the light outlet assembly 3 and improving the assembly efficiency. Moreover, the assembly method of the seal 8 and the light outlet assembly 3 in this example has better airtightness, which is beneficial to ensuring the light outlet effect.

[0037] Alternatively, in specific implementation, in an example embodiment of the present application, it can be a sealing ring. The sealing ring can be clamped between the bottom wall of the second groove 212 and the filter 31, and can be stacked in sequence with the filter 31, the high-temperature resistant gasket 32, and the mounting portion 341 of the light reflector 34, and be clamped between the bottom wall of the second groove 212 and the end face of the support rear cover 22 on the side where it is inserted into the second groove 212.

[0038] In a possible example, please refer to again Figure 4 , a limiting step 214 is formed on the groove side wall of the second groove 212 of the support front cover 21, and a surface of the high-temperature resistant gasket 32 that abuts against the seal 8 also partially abuts against the step surface of the limiting step 214.

[0039] Specifically, as Figure 4 shown, the limiting step 214 is disposed adjacent to the first groove 211. An end face of the seal 8 on the side of the installation groove opening and an edge area of the filter 31 can abut against the bottom wall of the second groove 212, and a bottom surface of the seal 8 can abut against the high-temperature resistant gasket 32 to limit the seal 8 and the filter between the high-temperature resistant gasket 32 and the bottom wall of the second groove 212. The area of the surface of the high-temperature resistant gasket 32 that contacts the bottom surface of the seal 8 can be larger than the area of the bottom surface of the seal 8, and a partial area that does not abut against the seal 8 can abut against the step, so that the high-temperature resistant gasket 32 can directly abut against the support front cover 21, thereby improving the structural stability of the light-emitting component 3 after assembly.

[0040] It can be seen that in this example, the limiting step 214 can be used to limit the high-temperature resistant gasket 32 to ensure the structural stability of the light-emitting component 3 after assembly.

[0041] In a possible example, a mating component 213 is provided on an outer wall of the bottom of the second groove 212; the air guiding channel member 5 includes a first air guiding housing and a second air guiding housing. The second air guiding housing is provided with a third groove. The first air guiding housing is snap-fitted at a first notch portion of the third groove. A channel air inlet hole is formed by enclosing a second notch portion of the third groove and a part of the first air guiding housing. A snap 531 that mates with the mating component 213 is provided at an end of the second notch portion away from the bottom of the third groove. The second air guiding housing and the support front cover 21 are connected through the snap 531 and the mating component 213.

[0042] In a specific example, please refer to again Figure 7 , as Figure 7 shown, the bottom wall of the second groove 212 is larger than the bottom wall of the first groove 211, and a mating component 213 is provided on an outer wall of the bottom of the second groove 212. The air guiding channel member 5 includes a first air guiding housing and a second air guiding housing, and the second air guiding housing is provided with a third groove.

[0043] Specifically, the third groove includes a first notch portion and a second notch portion. The first air guide housing is snap-fitted at the end where the notch of the third groove of the second air guide housing is located, and covers the first notch portion of the third groove, so that the second notch portion of the third groove and a part of the first air guide housing enclose an air inlet hole of the channel. That is, the first air guide housing covers a part of the notch of the third groove, making the remaining notch of the third groove become the air inlet hole of the channel.

[0044] A buckle 531 for cooperating with the cooperating component 213 is provided at one end of the third groove away from the bottom of the groove, and the buckle 531 is higher than the plane where the notch of the third groove is located, so that the air guide channel member 5 formed by the first air guide housing and the second air guide housing can be hung on the cooperating component 213 through the buckle 531, improving the installation efficiency while ensuring the stability of the structural connection.

[0045] It can be seen that in this example, when the first air guide housing is snap-fitted on the third notch of the second air guide housing and the buckle 531 of the second air guide housing is snap-fitted on the cooperating component 213, the end face where the third notch of the second air guide housing is located faces the support member 2, enabling the air inlet hole of the channel formed by the third notch and a part of the first air guide housing to be quickly aligned and communicated with the air outlet through hole, improving the assembly efficiency.

[0046] In a possible example, the hair remover may include a first air guide channel member 51 and a second air guide channel member 52, increasing the number of air guide channel members 5, allowing air in the space to enter the air guide channel member 5 in time, and improving the heat dissipation efficiency.

[0047] Wherein, a first air outlet through hole and a second air outlet through hole are formed in the side wall of the second groove 212. The first air guide channel member 51 communicates with the first air outlet through hole, and the second air guide channel member 52 communicates with the second air outlet through hole.

[0048] Specifically, the hole wall of the first air outlet through hole extends outward from the second groove 212 to form a first air guide pipe, and the hole wall of the second air outlet through hole extends outward from the second groove 212 to form a second air guide pipe.

[0049] The first end of the first air guiding channel member 51 includes a first channel air inlet hole 511. When the first end of the first air guiding channel member 51 is connected to the support member 2, the first air guiding pipe is placed into the first channel air inlet hole 511. The second end of the first air guiding channel member 51 extends along the support front cover 21 towards the support rear cover 22 to the tail end of the housing 1 and abuts against the inner wall of the tail end of the housing 1. The second end of the first air guiding channel member 51 includes a first channel air outlet hole communicating with the heat dissipation air outlet hole at the tail end of the housing 1. The second end of the second air guiding channel member 52 includes a second channel air inlet hole 521. When the second end of the second air guiding channel member 52 is connected to the support member 2, the second air guiding pipe is placed into the second channel air inlet hole 521. The second end of the second air guiding channel member 52 extends along the support front cover 21 towards the support rear cover 22 to the tail end of the housing 1 and abuts against the inner wall of the tail end of the housing 1. The second end of the second air guiding channel member 52 includes a second channel air outlet hole communicating with the heat dissipation air outlet hole at the tail end of the housing 1. At one end of the second notch portion of the first air guiding channel member 51 and the second air guiding channel member 52 away from the bottom of the third groove, there is a buckle 531 cooperating with the cooperating member 213. The first air guiding channel member 51, the second air guiding channel member 52 and the support front cover 21 are connected through the buckle 531 and the cooperating member 213.

[0050] Wherein, between the first air guiding housing of the first air guiding channel member 51 and the first air guiding housing of the second air guiding channel member 52, they are connected through a first connecting member and a second connecting member. It can be understood that between the second air guiding housing of the first air guiding channel member 51 and the second air guiding housing of the second air guiding channel member 52, they can be connected through a third connecting member to improve the installation efficiency.

[0051] It can be seen that in this example, by providing a plurality of air guiding channel members 5, heat accumulation in the support member 2 is prevented, and the heat dissipation efficiency of the heat dissipation component is improved.

[0052] In a possible example, an air inlet baffle is further provided around the hole of the channel air inlet hole. The air inlet baffle extends along the direction away from the bottom of the third groove, further improving the sealing performance between the channel air inlet hole and the air outlet through hole.

[0053] In a possible example, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 、 Figure 9 and Figure 10 , Figure 8 is a three-dimensional example diagram of the hair remover in Embodiment 2 provided by the embodiment of the present application; Figure 9 is a cross-sectional view of the hair remover in Embodiment 2 provided by the embodiment of the present application; Figure 10 is provided by the embodiment of the present application Figure 9 The enlarged schematic diagram at B. As shown in the figure, the cold compress member 4 is in a sheet structure or a block structure.

[0054] Please refer to again Figures 1 - 10 , the hair removal device further includes a refrigerating member 6, a heat dissipating member 7 and a blower 9; the blower 9 is arranged at one end of the supporting rear cover 22 away from the supporting front cover 21, an air inlet through hole is formed in the rear end face of the supporting rear cover 22, and the air outlet hole of the blower 9 is communicated with the air inlet through hole; if the cold compress member 4 is in a block structure, a contact through hole is formed in the side wall of the first groove 211, the refrigerating member 6 is snap-fitted in the contact through hole, and the refrigerating end of the refrigerating member 6 abuts against the part of the cold compress member 4 located in the supporting front cover 21, and the heat dissipating end of the refrigerating member 6 abuts against the first end of the heat dissipating member 7 to conduct heat to the heat dissipating member 7; the second end of the heat dissipating member 7 extends to the air inlet hole formed in the blower 9.

[0055] In a specific example, the cold compress member 4 is in a sheet structure or a block structure, and the hair removal device further includes a refrigerating member 6, a heat dissipating member 7 and a blower 9.

[0056] The front end of the supporting rear cover 22 is inserted into the second groove 212. Specifically, one of the supporting front cover 21 is provided with a buckle and a clamping groove, and the other of the supporting rear cover 22 is provided with a buckle and a clamping groove. For example, please refer to Figure 7 , as Figure 7 shown, the supporting rear cover 22 is provided with a second buckle 221, the supporting front cover 21 is provided with a first clamping groove 215 matching with the second buckle 221, and the second buckle 221 can be inserted into the first clamping groove 215 to realize clamping connection, so as to realize the connection and fixation of the supporting front cover 21 and the supporting rear cover 22. The end of the supporting rear cover 22 away from the supporting front cover 21 is the rear end of the supporting rear cover 22, a blower mounting seat 222 is arranged at the rear end of the supporting rear cover 22, and the blower 9 is arranged on the blower mounting seat 222. An air inlet through hole is formed in the rear end face of the supporting rear cover 22, and the air inlet through hole communicates with the space formed by enclosing the supporting rear cover 22 and the second groove 212. The air outlet hole of the blower 9 is communicated with the air inlet through hole of the supporting rear cover 22, so that the blower 9 can send air into this space through the air inlet through hole, thereby improving the heat dissipation efficiency.

[0057] Please refer to again Figure 4 , Figure 6 and Figure 7As shown in the figure, if the cold compress 4 is a block structure, the side wall of the first groove 211 can be provided with a contact through hole that only accommodates the refrigeration component 6. Since the cold compress 4 is a block, the contact through hole can be blocked to ensure the sealing of the cavity 1201 formed by the cold compress 4, the light output component 3 and the support front cover 21. The refrigeration component 6 is arranged in the contact through hole, which further reduces the volume of the device. The refrigeration end of the refrigeration component 6 abuts against the cold compress 4 located in the support front cover 21, and the heat dissipation end of the refrigeration component 6 abuts against the first end of the heat dissipation component 7 to cool the cold compress 4 faster and improve the refrigeration effect. The other end of the refrigeration component 6 conducts heat to the heat dissipation component 7. The second end of the heat dissipation component 7 extends to the air inlet hole provided on the fan 9, so that when the fan 9 takes in air, the heat of the heat dissipation component 7 is taken away, thereby improving the heat dissipation efficiency. When there are two or more air guide channel members 5, for example, including a first air guide channel member 51 and a second air guide channel member 52, the heat sink 7 can be arranged between the first air guide channel member 51 and the second air guide channel member 52, so as to further improve the device's compactness and thereby reduce its volume.

[0058] If the cold compress 4 is a sheet structure, please refer to Figure 9 and Figure 10 As shown in the figure, the refrigeration component 6 can be set on the side wall of the first groove 211, the refrigeration end of the refrigeration component 6 abuts against the cold compress component 4, and the heat dissipation end of the refrigeration component 6 abuts against the heat dissipation component 7, thereby realizing cooling of the cold compress component 4.

[0059] In one possible example, see again Figure 6 and Figure 7 ,like Figure 6 and Figure 7 As shown, the heat sink 7 includes a cover plate 71, a heat pipe 72 and a heat sink component 73; the first end of the heat pipe 72 is in contact with the heat sink end of the refrigeration component 6 through the cover plate 71, and the second end of the heat pipe 72 extends to the air inlet hole provided on the fan 9; the heat sink component 73 is arranged at the second end of the heat pipe 72, and the heat sink component 73 is provided with a heat sink fin group, and the two ends of the fins in the heat sink fin group extend to the air inlet hole provided on the shell 1 and the air inlet hole of the fan 9 respectively.

[0060] In the specific example, please combine Figure 2As shown in the figure, the shell 1 is provided with an air inlet, and the air inlet of the fan 9 can be opposite to the air inlet provided in the shell 1. The hair removal device can also include a filter 14, which is located in the shell and covers the air inlet of the shell 1 to prevent external dust and other objects from entering, thereby extending the service life of the internal components. The heat sink 7 includes a cover plate 71, a heat pipe 72 and a heat sink component 73. One end face of the cover plate 71 abuts against the heat dissipation end of the refrigeration component 6 to increase the contact area with the refrigeration component 6, thereby improving the heat conduction efficiency. The first end of the heat pipe 72 abuts against the other end face of the cover plate 71, and the heat sink component 73 is sleeved on the second end of the heat pipe 72. The second end of the heat pipe 72 extends to the air inlet provided on the fan 9, so that the heat sink component 73 is opposite to the air inlet provided on the fan 9, thereby accelerating the heat dissipation efficiency of the heat sink component 73. Specifically, the heat dissipation component 73 is provided with a heat dissipation fin group, and the two ends of the fins in the heat dissipation fin group extend toward the air inlet hole opened on the shell 1 and the air inlet hole of the fan 9 respectively, that is, a heat dissipation air duct is formed between two adjacent fins in the heat dissipation fin group, and the heat dissipation air duct connects the air inlet hole of the shell 1 and the air inlet hole of the fan 9.

[0061] It can be seen that in this example, one end of the heat sink 7 abuts against the refrigeration element 6 , and the heat sink component 73 at the other end of the heat sink 7 is located between the air inlet of the fan 9 and the air inlet of the shell 1 , thereby improving the heat dissipation efficiency of the heat sink 7 .

[0062] In one possible example, see Figure 7 When the cold compress 4 is a block structure, the circumferential side surface of the cold compress 4 is provided with one of the first limiting card groove or the first limiting card protrusion 41, and the inner side wall of the first groove 211 is provided with the other of the first limiting card groove or the first limiting card protrusion 41, and the first limiting card protrusion 41 is engaged in the first limiting card groove; See also Figure 10 and Figure 11 , Figure 11 It is an exploded schematic diagram of the front cover, cold compress, light output assembly and support member in the second embodiment provided by the embodiment of the present application. When the cold compress 4 is the sheet structure, the cold compress 4 includes a sheet body and an annular clamping protrusion 42, and the annular clamping protrusion 42 is arranged around the circumferential side of the sheet body; the housing 1 is formed with an annular baffle 132 at the light output end, and the annular baffle 132 extends toward the central axis direction of the light output port, and the annular clamping protrusion 42 is sandwiched between the annular baffle 132 and the notch end of the supporting front cover 21 in the first groove 211.

[0063] In a specific example, when the cold compress member 4 is in the form of a sheet structure, the cold compress member 4 includes a sheet body and an annular convex 42, and the annular convex 42 is arranged around the circumferential side of the sheet body; an annular baffle 132 is formed at the light-emitting end of the housing 1, and the annular baffle 132 extends along the central axis direction of the light outlet, and the annular convex 42 is clamped between the annular baffle 132 and the notch end of the first groove 211 of the support front cover 21.

[0064] Specifically, in the direction of the light beam emitted from the light outlet, the thickness of the block structure is greater than that of the sheet structure. Under the same effect, the size of the light outlet corresponding to the cold compress member 4 of the block structure can be smaller than the size of the light outlet corresponding to the cold compress member 4 of the sheet structure. In this way, when the hair removal device uses the cold compress member 4 in the form of a sheet structure, the size of its light outlet is relatively large, which is more suitable for large-area hair removal, such as underarm hair removal. When the hair removal device uses the cold compress member 4 in the form of a block structure, the size of its light outlet is smaller, which is convenient for the user to use on a smaller hair removal area, such as the beard on the mouth. At the same time, when the hair removal device uses the cold compress member 4 in the form of a block structure, the portability of the hair removal device can also be improved.

[0065] It can be seen that in this example, designing the hair removal device according to the needs by using the cold compress member 4 in the form of a sheet structure or a block structure can expand the application scenarios of the hair removal device and is beneficial to meeting the usage requirements of different users.

[0066] In an embodiment of the present application, when the cold compress member 4 is in the form of a sheet structure, the cold compress member 4 includes a sheet body and an annular convex 42, and the annular convex 42 is arranged around the circumferential side of the sheet body; an annular baffle 132 is formed at the light-emitting end of the housing 1, and the annular baffle 132 extends along the central axis direction of the light outlet, and the annular convex 42 is clamped between the annular baffle 132 and the notch end of the first groove 211 of the support front cover 21.

[0067] Among them, the shape of the sheet body can be the same as the shape of the light outlet and can cover the entire light outlet, so that the light beam emitted by the light-emitting member 33 first passes through the filter 31, then passes through the cold compress member 4, and finally is emitted to the outside of the hair removal device. The annular convex 42 can be used to fix the cold compress member 4.

[0068] The housing 1 may include an upper housing 11, a lower housing 12, and a front cover 13. The front cover 13 is circumferentially provided with a plurality of first snap fasteners 133 at intervals, and can be respectively snap-connected to the upper housing 11 and the lower housing 12 through the first snap fasteners 133 to enclose and form an installation space. The front cover 13 includes a main body portion 131 and an annular baffle 132. The annular baffle 132 encloses to form a light outlet. The sheet body of the cold compress member 4 can be inserted into the light outlet and cover the light outlet. The annular convex 42 abuts against the side surface of the annular baffle 132 facing the inner cavity of the housing 1 to position the cold compress member 4. Further, the end surface of the support front cover 21 forming the notch end of the first groove 211 can abut against the side surface of the sheet body facing the installation space to limit and clamp the cold compress member 4 between the annular baffle 132 and the support front cover 21.

[0069] Further, please refer to Figure 11 . The main body portion 131 of the front cover 13 may further be provided with a limiting protrusion 134. The sheet body can be snap-connected between the limiting protrusion 134 and the annular baffle 132 to further improve the stability of the assembly of the cold compress member 4. Further, the limiting protrusion 134 is formed with a guiding inclined surface inclined towards the light outlet to improve the convenience of assembling the cold compress member 4 and the front cover 13.

[0070] It can be seen that in this example, when the cold compress member 4 is in a sheet structure, an annular convex 42 is provided for the cold compress member 4 to be positioned through the annular convex 42 and the front cover 13, which is beneficial to improving the convenience of assembling the front cover 13 and the cold compress member 4.

[0071] In a possible example, the light-emitting assembly further includes a waterproof member 1301, and the waterproof member 1301 is disposed around the groove side wall of the first groove 211.

[0072] Wherein, the waterproof member 1301 can be directly prepared from a waterproof material, or the waterproof member 1301 can be a structure with a waterproof coating.

[0073] Specifically, the waterproof member 1301 can be a cylindrical structure, and the first groove 211 is sleeved on its outer surface.

[0074] It can be seen that in this example, by providing the waterproof member 1301, the cavity 1201 can be further isolated. While avoiding the condensed water in the cavity 1201 from affecting the sensitive components and affecting the service life of the hair removal device, it can also prevent external water molecules from entering the cavity 1201 and affecting the light-emitting effect.

[0075] In a possible example, when the cold compress member 4 is in a block structure, one of a first limiting card slot or a first limiting convex 41 is provided on the circumferential side surface of the cold compress member 4, and the other of the first limiting card slot or the first limiting convex 41 is provided on the groove side wall of the first groove 211, and the first limiting convex 41 is snap-connected into the first limiting card slot.

[0076] Specifically, when the cold compress 4 is a block structure, most of the structure of the cold compress 4 can be inserted into the first groove 211 to limit the cold compress 4. The cold compress 4 can cover the light outlet to ensure that the light beam is emitted outward through the cold compress 4. The structure of the housing 1 forming the light outlet can refer to the above description of the structure of the housing 1.

[0077] Specifically, the first limiting protrusion 41 and the first limiting groove may be annular; or, a plurality of first limiting protrusions 41 may be provided at intervals along the circumferential side of the cold compress 4, and the first limiting groove may be formed correspondingly on the groove side wall of the first groove 211. In this way, the stability of the assembly of the cold compress 4 and the supporting front cover 21 can be further improved.

[0078] It can be seen that in this example, by providing matching first limiting protrusions 41 and first limiting grooves on the circumferential side surfaces of the cold compress 4 and the side walls of the first groove 211, the cold compress 4 and the supporting front cover 21 can be installed and fixed, thereby preventing the cold compress 4 from shaking or detaching.

[0079] Please refer again Figure 2 , Figure 3 and Figure 4 As shown in the figure, in an embodiment of the present application, the shell 1 includes an upper shell 11, a lower shell 12 and a front cover 13, and the second end of the cold compress 4 is inserted into the first groove 211; a second limiting groove 1101 is formed on the side of the front cover 13 facing the inner cavity; a second limiting protrusion 1102 is formed at the open end supporting the front cover 21 in the first groove 211, and the second limiting protrusion 1102 is inserted into the second limiting groove 1101.

[0080] Specifically, the front cover 13 is provided with a plurality of first buckles 133 spaced apart along the circumferential direction, and can be respectively engaged with the upper shell 11 and the lower shell 12 through the first buckles 133 to enclose and form an inner cavity.

[0081] In a specific implementation, the second limiting protrusion 1102 can be directly formed by extending a portion of the end surface of the supporting front cover 21 at the open end of the first groove 211 in a direction away from the second groove 212. Alternatively, in one embodiment of the present application, the second limiting protrusion 1102 includes a plug-in portion 1102a and a limiting portion 1102b, the limiting portion 1102b extends in a direction away from the central axis of the first groove 211 and abuts against the front cover 13, and the plug-in portion 1102a extends in a direction along the central axis of the first groove 211 and is inserted into the second limiting groove 1101. In this way, during assembly, the supporting front cover 21 can not only be positioned with the front cover 13 through the limiting portion 1102b, but also can be limited with the front cover 13 through the limiting portion 1102b, so as to ensure that the front cover 13 and the supporting front cover 21 are assembled in place, further improving the stability of the cold compress 4 after assembly.

[0082] It can be seen that in this example, the positioning of the support front cover 21 and the front cover 13 can be achieved through the second limit convex 1102 and the second limit slot 1101, thereby improving the convenience and accuracy of assembly.

[0083] In a possible example, please refer back to Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 and Figure 9 , the hair removal device further includes a power adapter. The power adapter is partially placed in the inner cavity of the housing 1 and is connected to the electrical components inside the hair removal device, such as the light emitting component 3, the control component, etc. A capacitor is provided inside the power adapter. It can be understood that a detachable part can also be provided at one end of the power adapter placed in the housing 1, so that the power adapter and the main body of the hair removal device can be detached, which is convenient for storage and improves the user experience.

[0084] It can be seen that in this example, by setting the capacitor inside the power adapter, while ensuring the safety and stability of power supply, the volume of the hair removal device is further reduced, improving the user experience.

[0085] In a possible example, please refer to Figure 5 . As Figure 5 shown, the hair removal device further includes a temperature acquisition component 1001; an installation groove is further formed on the outer wall of the first groove 211, and the temperature acquisition component 1001 is partially arranged in the installation groove.

[0086] In a specific example, the hair removal device further includes a temperature acquisition component 1001. As Figure 5 and Figure 7 shown, an installation groove is formed on the outer wall of the first groove 211, and the temperature acquisition component 1001 is partially arranged in the installation groove for acquiring the temperature of the cold compress part 4 in the first groove 211 and transmitting it to the control component.

[0087] It can be seen that in this example, the temperature of the cold compress part 4 is acquired through the temperature acquisition component 1001, so that the control component can obtain the real-time temperature, improving the real-time performance and accuracy of temperature control.

[0088] In a possible example, the hair removal device further includes a Bluetooth component. The Bluetooth component connects the power adapter and the control component, enabling the user's terminal device to connect to the hair removal device through the Bluetooth component, and then controlling the hair removal device on the terminal device side, improving the user experience.

[0089] The above has introduced the embodiments of the present application in detail. Specific examples are used herein to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
