Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to a hair removal device. Background Art

[0002] A hair removal device utilizes the principle of photothermal therapy to remove hair. It emits intense pulsed light of a specific wavelength, which acts directly at the root of the hair follicles through the pores, destroying the follicle tissue and causing it to gradually shrink, achieving the desired effect. However, in existing handheld hair removal devices, the sapphire cooling element, due to its low temperature, can cause moisture in the air to condense and adhere to the sapphire cooling element during use. This can affect the light output and hinder the effectiveness of hair removal and cleaning. Summary of the Invention

[0056] In a specific example, the shell 1 of the hair removal device can be oval, gun-shaped or other shapes, and no further restrictions are imposed here. The material of the shell 1 can be plastic, aluminum alloy, ceramic, etc., and no further restrictions are imposed here. The shell 1 is composed of an upper shell 11, a lower shell 12 and a front cover 13. The front cover 13 is mounted on the front end of the upper shell 11 and the lower shell 12 after they are combined to form the inner cavity of the shell 1. The front cover 13 is provided with a light outlet so that the hair removal device can emit light smoothly. When the hair removal device is a wiring-type hair removal device, the rear end of the hair removal device is connected to the connecting line of the power adapter to achieve high-power continuous power supply.

[0057] The hair removal device also includes a support member 2, a light output component 3, a seal 8, a cold compress 4 and at least one air guide channel member 5, and the support member 2, the light output component 3, the seal 8, the cold compress 4 and at least one air guide channel member 5 are arranged in the inner cavity of the shell 1. Among them, the support member 2 includes a support front cover 21 and a support back cover 22. The side of the support front cover 21 facing the light output port of the shell 1 is the front end face of the support front cover 21, and the side of the support front cover 21 facing away from the light output port is the rear end face of the support front cover 21. The front end face of the support front cover 21 is provided with a first groove 211, and the rear end face of the support front cover 21 is provided with a second groove 212. The bottom wall of the first groove 211 and the bottom wall of the second groove 212 are connected and form a through hole. The front end of the support back cover 22 is inserted into the second groove 212 and covers the notch of the second groove 212.

[0058] The side wall of the first end of the air guide channel member 5 includes a channel air inlet hole that cooperates with the air guide duct. When the first end of the air guide channel member 5 is connected to the support front cover 21, the air guide duct is placed in the channel air inlet hole, so that the interior of the air guide channel member 5 is connected to the space formed by the second groove 212 and the support back cover 22, and the air in the space is prevented from overflowing from the connection between the channel air inlet hole and the air outlet hole when entering the air guide channel member 5, thereby improving the sealing performance. The second end of the air guide channel member 5 extends along the support front cover 21 toward the support back cover 22 to the rear end of the shell 1, and abuts against the inner wall of the rear end of the shell 1. The second end of the air guide channel member 5 includes a channel air outlet hole that is connected to the heat dissipation air outlet hole at the rear end of the shell 1, so as to discharge the air in the air guide channel member 5 out of the hair removal device, making the internal structure of the hair removal device compact while ensuring the heat dissipation effect.

[0059] Part of the structure of the light emitting component 3 is sandwiched between the bottom wall of the second groove 212 and the support back cover 22; the sealing member 8 is sandwiched between the bottom wall of the second groove 212 and the light emitting component 3. The cold compress 4 is connected to the support front cover 21 and / or the shell 1, and covers the light outlet of the shell 1. The cold compress 4, the light emitting component 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 component 3 will pass through the cavity 1201 and eventually pass through the cold compress 4 to be emitted to the outside of the hair removal device. In the present application, under the irradiation of the pulsed light, the air pressure in the cavity 1201 enclosed by the cold compress 4, the light emitting component 3 and the support front cover 21 will decrease, so that the condensed water generated on the cold compress 4 can be vaporized, thereby reducing the air density in the cavity 1201 and forming a vacuum-like environment, thereby avoiding the regeneration of condensed water on the cold compress 4, which affects 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 output component 3, prevent external air from entering the cavity 1201 to form condensed water, and avoid the condensed water from refracting the pulsed light excited by the light output component 3, which is beneficial to improving the light output effect of hair removal.

[0060] Specifically, the material of the sealing member 8 can be rubber, plastic, graphite or metal.

[0061] Specifically, the cold compress 4 can be made of sapphire, ceramic, or quartz, etc. When the cold compress 4 is made of sapphire, it can effectively reduce the heat on the side of the hair removal device that is in contact with the user during use, increase user comfort, and improve the conduction efficiency of the light beam, thereby improving the hair removal effect.

[0062] For details, please combine Figure 5-Figure 7 , Figure 5 This is a schematic diagram of the assembly of part of the structure of the hair removal device in Example 1 provided in the embodiments of the present application; Figure 6 for Figure 5 Exploded view of the structure shown.

[0063] Please refer to Figure 7 The sealing member 8 includes 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;

[0064] The light-emitting component 3 includes: a filter 31, a high-temperature resistant gasket 32, a light-emitting component 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 the side of the sealing component 8 facing away from the notch of the installation groove, and the high-temperature resistant gasket 32 ​​forms a second light-emitting through hole 321 that communicates with the first light-emitting through hole 81; the light-emitting component 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 component 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.

[0065] Specifically, the light emitting element 33 may be a lamp tube for generating laser or pulsed light. A surrounding winding 331 may be provided around the outer periphery of the lamp tube. The provision of the winding 331 is beneficial for improving the light efficiency of the light emitting element 33 .

[0066] Specifically, the reflector 34 is arranged around the light-emitting element 33 and is formed with an opening toward the light outlet. In this way, the reflector 34 can reflect the light emitted by the light-emitting element 33 so that it is concentrated and emitted toward the light outlet, thereby improving the lighting effect. The reflector 34 can be made of aluminum alloy, stainless steel, or a coating material, etc. Specifically, the reflector 34 includes a reflective body 342 and a mounting portion 341. At least part of the structure of the reflective body 342 is an arc-shaped structure arranged around the light-emitting element 33. The mounting portion 341 is connected to both sides of the opening formed by the reflective body 342, and is bent and extended in the direction away from the outlet to be sandwiched between the high-temperature resistant gasket 32 ​​and the supporting back cover 22.

[0067] 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 high-temperature resistant gasket 32 ​​can be made of silicone, aluminum alloy, or ceramic. Providing the high-temperature resistant gasket 32 ​​between the filter and the light-emitting element 33 can achieve thermal insulation, preventing heat energy from the reflective cup from being transferred to the filter and affecting the filter's service life. 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 are not further limited here.

[0068] In a specific implementation, the seal 8 includes a mounting groove, and the end surface on one side of the mounting groove is in contact with the portion 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-emitting through hole 81, and the first light-emitting through hole 81 is arranged directly opposite the through hole. In this way, the pulsed light excited by the light-emitting element 33 can sequentially pass through the second light-emitting through hole 321 and the first light-emitting through hole 81, and then pass through the filter 31 to enter the cavity 1201 through the through hole, and then pass through the cold compress 4 to be emitted outside the hair removal device.

[0069] As can be seen, in this example, the seal 8 and the filter 31, high-temperature resistant gasket 32, light-emitting element 33, and reflector 34 in the light-emitting assembly 3 can be stacked and sandwiched between the support front cover 21 and the support rear cover 22. Therefore, the light-emitting assembly 3 can be installed and fixed by connecting the support front cover 21 and the support rear cover 22, which is conducive to improving the convenience and efficiency of assembling the light-emitting assembly 3. In addition, the assembly method of the seal 8 and the light-emitting assembly 3 in this example is more airtight, which is conducive to ensuring the light output effect.

[0070] Alternatively, in a specific implementation, in an embodiment of the present application, it can be a sealing ring, which 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 reflector 34, and clamped between the bottom wall of the second groove 212 and the end face of the support back cover 22 on the side inserted into the second groove 212.

[0071] In one possible example, see again Figure 4 The supporting front cover 21 forms a limiting step 214 on the side wall of the second groove 212 , and the side 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 .

[0072] Specifically, if Figure 4 As shown, the limiting step 214 is provided adjacent to the first groove 211. The end face of the seal 8 on the side of the mounting groove notch and the edge area of ​​the filter 31 can abut against the bottom wall of the second groove 212, and the 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 ​​in contact with the bottom surface of the seal 8 can be larger than the area of ​​the bottom surface of the seal 8, and the partial area not abutting against the seal 8 can abut against the step, so that the high-temperature resistant gasket 32 ​​can directly abut against the supporting front cover 21, thereby improving the stability of the structure of the light output component 3 after assembly.

[0073] 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 stability of the structure of the light output component 3 after assembly.

[0074] In a possible example, a mating component 213 is provided on the outer wall of the bottom of the second groove 212; the air guide channel member 5 includes a first air guide shell and a second air guide shell, the second air guide shell is provided with a third groove, the first air guide shell is snap-fitted into the first notch portion of the third groove, the second notch portion of the third groove and part of the first air guide shell enclose the channel air inlet hole, and a buckle 531 that cooperates with the mating component 213 is provided at one end of the second notch portion away from the bottom of the third groove, and the second air guide shell and the support front cover 21 are connected through the buckle 531 and the mating component 213.

[0075] For specific examples, please refer to Figure 7 ,like Figure 7 As shown, the bottom wall of the second groove 212 is larger than the bottom wall of the first groove 211, and a matching component 213 is provided on the outer wall of the bottom of the second groove 212. The air guide channel member 5 includes a first air guide housing and a second air guide housing, and the second air guide housing is provided with a third groove.

[0076] Specifically, the third groove includes a first notch portion and a second notch portion. The first air guide housing is snap-fitted onto the notch end of the third groove of the second air guide housing and covers the first notch portion of the third groove, so that the second notch portion of the third groove and a portion of the first air guide housing enclose a channel air inlet. That is, the first air guide housing covers a portion of the notch of the third groove, leaving the remaining portion of the notch of the third groove as the channel air inlet.

[0077] A buckle 531 that cooperates with the mating 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 composed of the first air guide shell and the second air guide shell can be hooked on the mating component 213 through the buckle 531, ensuring the stability of the structural connection while improving the installation efficiency.

[0078] It can be seen that in this example, the first air guide shell is buckled on the third slot of the second air guide shell. When the buckle 531 of the second air guide shell is buckled on the mating component 213, the end face of the third slot of the second air guide shell faces the support member 2, so that the third slot and the channel air inlet and air outlet holes formed by part of the first air guide shell can be quickly aligned and connected, thereby improving assembly efficiency.

[0079] In a possible example, the hair removal device may include a first air guide channel member 51 and a second air guide channel member 52, which increases the number of air guide channel members 5, allowing air in the space to enter the air guide channel members 5 in a timely manner, thereby improving heat dissipation efficiency.

[0080] The side wall of the second groove 212 defines a first air outlet hole and a second air outlet hole. The first air guide channel 51 is connected to the first air outlet hole, and the second air guide channel 52 is connected to the second air outlet hole.

[0081] Specifically, the hole wall of the first air outlet hole extends outward from the second groove 212 to form a first air duct, and the hole wall of the second air outlet hole extends outward from the second groove 212 to form a second air duct.

[0082] The first end of the first air guide channel member 51 includes a first channel air inlet hole 511. When the first end of the first air guide channel member 51 is connected to the support member 2, the first air guide duct is placed in the first channel air inlet hole 511. The second end of the first air guide channel member 51 extends along the support front cover 21 toward the support rear cover 22 to the rear end of the shell 1, and abuts against the inner wall of the rear end of the shell 1. The second end of the first air guide channel member 51 includes a first channel air outlet hole connected to the heat dissipation air outlet hole at the rear end of the shell 1. The second end of the second air guide channel member 52 includes a second channel air inlet hole 521. When the second end of the second air guide channel member 52 is connected to the support member 2, the second air guide duct is placed in the second channel air inlet hole 521. The second end of the second air guide channel member 52 extends along the support front cover 21 toward the support rear cover 22 to the rear end of the shell 1, and abuts against the inner wall of the rear end of the shell 1. The second end of the second air guide channel member 52 includes a second channel air outlet hole connected to the heat dissipation air outlet hole at the rear end of the shell 1. A buckle 531 that cooperates with the mating component 213 is provided at one end of the second notch portion of the first air guide channel member 51 and the second air guide channel member 52 away from the bottom of the third groove, and the first air guide channel member 51, the second air guide channel member 52 and the supporting front cover 21 are connected by the buckle 531 and the mating component 213.

[0083] The first air guide housing of the first air guide channel member 51 is connected to the first air guide housing of the second air guide channel member 52 by a first connecting member and a second connecting member. It is understood that the second air guide housing of the first air guide channel member 51 and the second air guide housing of the second air guide channel member 52 can be connected by a third connecting member to improve installation efficiency.

[0084] It can be seen that in this example, by providing a plurality of air guide channel members 5 , heat accumulation in the support member 2 is prevented, thereby improving the heat dissipation efficiency of the heat dissipation assembly.

[0085] In a possible example, an air inlet baffle is further provided around the channel air inlet hole, and the air inlet baffle extends in a direction away from the bottom of the third groove, so as to further improve the sealing between the channel air inlet hole and the air outlet hole.

[0086] In one possible example, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 、 Figure 9 and Figure 10 , Figure 8 This is a three-dimensional example diagram of the hair removal device in Example 2 provided in the embodiments of the present application; Figure 9 This is a cross-sectional view of the hair removal device in Example 2 provided in the embodiments of the present application; Figure 10 This embodiment of the present application provides Figure 9 An enlarged schematic diagram at point B. As shown in the figure, the cold compress 4 is a sheet-like structure or a block-like structure.

[0087] Please refer again Figures 1-10 The hair removal device also includes a refrigeration component 6, a heat dissipation component 7 and a fan 9; the fan 9 is arranged at one end of the support rear cover 22 away from the support front cover 21, and the rear end surface of the support rear cover 22 is provided with an air inlet hole, and the air outlet hole of the fan 9 is connected with the air inlet hole; if the cold compress 4 is a block structure, the side wall of the first groove 211 is provided with a contact through hole, the refrigeration component 6 is engaged and arranged in the contact through hole, and the cooling end of the refrigeration component 6 is in contact with the part of the cold compress 4 located in the support front cover 21, and the heat dissipation end of the refrigeration component 6 is in contact with the first end of the heat dissipation component 7 to conduct 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.

[0088] In a specific example, the cold compress 4 is a sheet-like structure or a block-like structure, and the hair removal device further includes a refrigeration component 6, a heat dissipation component 7 and a fan 9.

[0089] The front end of the support back cover 22 is inserted into the second groove 212. Specifically, the support front cover 21 is provided with one of the buckle and the slot, and the support back cover 22 is provided with the other of the buckle and the slot. For example, refer to Figure 7 ,like Figure 7 As shown, the support back cover 22 is provided with a second snap 221, and the support front cover 21 is provided with a first snap groove 215 that cooperates with the second snap 221. The second snap 221 can be inserted into the first snap groove 215 and snapped together, thereby achieving the connection and fixation between the support front cover 21 and the support back cover 22. The end of the support back cover 22 away from the support front cover 21 is the rear end of the support back cover 22. The rear end of the support back cover 22 is provided with a fan mounting seat 222, and the fan 9 is disposed on the fan mounting seat 222. The rear end surface of the support back cover 22 is provided with an air inlet hole, which connects to the space enclosed by the support back cover 22 and the second groove 212. The air outlet of the fan 9 is connected to the air inlet hole of the support back cover 22, so that the fan 9 can send air into the space through the air inlet hole, thereby improving the heat dissipation efficiency.

[0090] Please refer again Figure 4 、 Figure 6 and Figure 7As shown in the figure, if the cold compress 4 is a block-shaped 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 in a block shape, 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 size of the device. The cooling 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 sink 7 to cool the cold compress 4 faster and improve the cooling effect. The other end of the refrigeration component 6 conducts heat to the heat sink 7. The second end of the heat sink 7 extends to the air inlet hole provided on the fan 9, so that when the fan 9 takes in air, it takes away the heat of the heat sink 7, 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, further improving the device's compactness and thereby reducing its volume.

[0091] 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.

[0092] In one possible example, see again Figure 6 and Figure 7 ,like Figure 6 and Figure 7 As shown, the heat dissipation element 7 includes a cover plate 71, a heat pipe 72 and a heat dissipation component 73; the first end of the heat pipe 72 is in contact with the heat dissipation end of the refrigeration element 6 through the cover plate 71, and the second end of the heat pipe 72 extends to the air inlet hole opened on the fan 9; the heat dissipation component 73 is arranged at the second end of the heat pipe 72, and 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 to the air inlet hole opened on the shell 1 and the air inlet hole of the fan 9 respectively.

[0093] 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 of the shell 1. The hair removal device can also include a filter 14. The filter 14 is located inside 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.

[0094] It can be seen that in this example, one end of the heat sink 7 abuts the refrigeration element 6 , and the heat dissipation 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 housing 1 , thereby improving the heat dissipation efficiency of the heat sink 7 .

[0095] In one possible example, see Figure 7 When the cold compress 4 is a block-shaped structure, the circumferential side surface of the cold compress 4 is provided with one of the first limiting groove or the first limiting protrusion 41, and the inner side wall of the first groove 211 is provided with the other of the first limiting groove or the first limiting protrusion 41, and the first limiting protrusion 41 is engaged in the first limiting groove;

[0096] See also Figure 10 and Figure 11 , Figure 11 This is an exploded schematic diagram of the front cover, cold compress, light output assembly, and support member in Example 2 provided by the present application. When the cold compress 4 is a sheet-like structure, it comprises a sheet body and an annular retaining protrusion 42, which is disposed around the circumferential side of the sheet body. The housing 1 is formed with an annular baffle 132 at the light output end, extending toward the central axis of the light output port. The annular retaining protrusion 42 is sandwiched between the annular baffle 132 and the notch end of the supporting front cover 21 in the first groove 211.

[0097] In a specific example, when the cold compress 4 is a sheet-like 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 shell 1 is formed with an annular baffle 132 at the light-emitting end, and the annular baffle 132 extends toward the central axis of the light-emitting port, and the annular clamping protrusion 42 is clamped between the annular baffle 132 and the notch end of the supporting front cover 21 in the first groove 211.

[0098] Specifically, in the direction of the light beam emitting from the light outlet, the thickness of the block structure is greater than the thickness of the sheet structure. Under the same effect, the size of the light outlet provided for the cold compress 4 corresponding to the block structure can be smaller than the size of the light outlet provided for the cold compress 4 corresponding to the sheet structure. In this way, when the hair removal device adopts the cold compress 4 with 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 adopts the cold compress 4 with a block structure, the size of its light outlet is smaller, which is convenient for users to use for hair removal areas with smaller areas, such as the beard at the mouth. At the same time, when the hair removal device adopts the cold compress 4 with a block structure, the portability of the hair removal device can also be improved.

[0099] It can be seen that in this example, the hair removal device is designed with a cold compress 4 having a sheet structure or a block structure according to the needs, which can expand the application scenarios of the hair removal device and is conducive to meeting the usage needs of different users.

[0100] In one embodiment of the present application, when the cold compress 4 is a sheet-like structure, the cold compress 4 includes a sheet body and an annular latch 42, and the annular latch 42 is arranged around the circumferential side of the sheet body; the shell 1 is formed with an annular baffle 132 at the light-emitting end, and the annular baffle 132 extends toward the central axis of the light-emitting port, and the annular latch 42 is clamped between the annular baffle 132 and the notch end of the support front cover 21 in the first groove 211.

[0101] The shape of the sheet body can be the same as that of the light outlet and can cover the entire light outlet, so that the light beam emitted by the light emitting element 33 first passes through the filter 31, then passes through the cold compress 4, and finally is emitted to the outside of the hair removal device. The annular clamping protrusion 42 can be used to fix the cold compress 4.

[0102] The shell 1 may include an upper shell 11, a lower shell 12 and a front cover 13. The front cover 13 is provided with a plurality of first snaps 133 spaced apart along the circumference, and can be snapped with the upper shell 11 and the lower shell 12 respectively through the first snaps 133 to enclose and form an installation space. The front cover 13 includes a main body 131 and an annular baffle 132. The annular baffle 132 encloses and forms a light outlet. The sheet body of the cold compress 4 can be inserted into the light outlet and cover the light outlet. The annular snap protrusion 42 abuts against the side of the annular baffle 132 facing the inner cavity of the shell 1 to position the cold compress 4. Furthermore, the end face of the notch end of the supporting front cover 21 forming the first groove 211 can abut against the side of the sheet body facing the installation space to limit and clamp the cold compress 4 between the annular baffle 132 and the supporting front cover 21.

[0103] Further, see Figure 11 The main body 131 of the front cover 13 can also be provided with a limiting protrusion 134. The main body of the sheet can be clamped between the limiting protrusion 134 and the annular baffle 132 to further enhance the stability of the assembly of the cold compress 4. Furthermore, the limiting protrusion 134 is formed with a guide slope inclined toward the light outlet to enhance the convenience of assembly of the cold compress 4 and the front cover 13.

[0104] It can be seen that in this example, when the cold compress 4 is a sheet structure, an annular locking protrusion 42 is provided for the cold compress 4 to be positioned with the front cover 13 through the annular locking protrusion 42, which is conducive to improving the convenience of assembling the front cover 13 and the cold compress 4.

[0105] In a possible example, the light output assembly further includes a waterproof member 1301 , and the waterproof member 1301 is disposed around a side wall of the first groove 211 .

[0106] The waterproof member 1301 may be directly made of a waterproof material, or the waterproof member 1301 may be a structure having a waterproof coating.

[0107] Specifically, the waterproof component 1301 may be a cylindrical structure, and the first groove 211 is sleeved on the outer surface thereof.

[0108] It can be seen that in this example, the cavity 1201 can be further isolated by providing a waterproof component 1301, which can prevent the condensed water in the cavity 1201 from affecting sensitive components and affecting the service life of the hair removal device, and can also prevent external water molecules from entering the cavity 1201 and affecting the light output effect.

[0109] In a possible example, when the cold compress 4 is a block structure, the circumferential side of the cold compress 4 is provided with a first limiting groove or a first limiting protrusion 41, and the groove side wall of the first groove 211 is provided with the first limiting groove or the other of the first limiting protrusion 41, and the first limiting protrusion 41 is engaged in the first limiting groove.

[0110] Specifically, when the cold compress 4 is a block-shaped structure, the majority of the cold compress 4 can be inserted into the first groove 211 to limit the position of 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.

[0111] Specifically, the first limiting protrusion 41 and the first limiting groove can be annular; alternatively, a plurality of first limiting protrusions 41 can be provided at intervals along the circumferential side of the cold compress 4, and the first limiting grooves can correspond to the sidewalls of the first groove 211. This can further improve the stability of the assembly between the cold compress 4 and the supporting front cover 21.

[0112] It can be seen that in this example, by arranging 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.

[0113] 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 of the first groove 211 supporting the front cover 21, and the second limiting protrusion 1102 is inserted into the second limiting groove 1101.

[0114] 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.

[0115] In a specific implementation, the second limiting protrusion 1102 can be directly formed by extending a portion of the end surface of the support 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 an inserting portion 1102a and a limiting portion 1102b, wherein 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 inserting portion 1102a extends along the central axis of the first groove 211 and is inserted into the second limiting groove 1101. In this way, during assembly, the support front cover 21 can not only be positioned with the front cover 13 by the limiting portion 1102b, but can also be limited by the limiting portion 1102b with the front cover 13, so as to ensure that the front cover 13 and the support front cover 21 are assembled in place, further improving the stability of the cold compress 4 after assembly.

[0116] It can be seen that in this example, the second limiting latch protrusion 1102 and the second limiting latch groove 1101 can realize the positioning of the front cover 21 and the front cover 13, thereby improving the convenience and accuracy of assembly.

[0117] In one possible example, see again Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 and Figure 9 The hair removal device also includes a power adapter, which is partially housed within the inner cavity of the housing 1 and connected to the electrical components within the hair removal device, such as the light output component 3 and the control component. The power adapter is equipped with a capacitor. It is understood that a detachable portion can also be provided at the end of the power adapter housed within the housing 1, allowing the power adapter to be separated from the hair removal device body for easier storage and an improved user experience.

[0118] It can be seen that in this example, the capacitor is set in the power adapter, which not only ensures the safety and stability of power supply, but also further reduces the size of the hair removal device and improves the user experience.

[0119] In one possible example, combine Figure 5 .like Figure 5 As shown, the hair removal device further includes a temperature collection component 1001; an installation groove is further provided on the outer wall of the first groove 211, and the temperature collection component 1001 is partially disposed in the installation groove.

[0120] In a specific example, the hair removal device further includes a temperature collection component 1001, such as Figure 5 and Figure 7 As shown, a mounting groove is provided on the outer wall of the first groove 211 , and the temperature collection component 1001 is partially disposed in the mounting groove for collecting the temperature of the cold compress 4 in the first groove 211 to transmit the temperature to the control component.

[0121] It can be seen that in this example, the temperature of the cold compress 4 is collected by the temperature collection component 1001, so that the control component can obtain the real-time temperature, thereby improving the real-time performance and accuracy of temperature control.

[0122] In a possible example, the hair removal device also includes a Bluetooth component, which connects the power adapter and the control component, so that the user's terminal device can connect to the hair removal device through the Bluetooth component, and then control the hair removal device on the terminal device side, thereby improving the user experience.

[0123] The above is a detailed introduction to the embodiments of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. At the same time, for those skilled in the art, based on the ideas of the present application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
