Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of hair removal devices, in particular a hair removal device. BACKGROUND

[0002] A hair removal device can generate a significant amount of heat during operation. This heat can originate from the lamp itself. As the main component of the device, the lamp can produce a substantial amount of heat during operation. If this heat is not dissipated promptly, the lamp's lifespan can be shortened. Simultaneously, the heat generated by the lamp can radiate to other parts of the device, such as components designed to come into contact with the skin. If these components reach a high temperature, the user may experience a burning sensation. Furthermore, current designs of hair removal devices can emit light unevenly during operation.

[0003] Furthermore, it can be difficult to maintain firm contact between the trigger wire and the lamp during use of the hair removal device. If the contact between the trigger wire and the lamp is loose, it may be difficult for the trigger wire to activate the lamp, and the cost of replacing the trigger wire may increase.

[0078] To clarify and explain the aforementioned objectives, features, and advantages of this disclosure, the technical solutions of the embodiments of this disclosure are described below with reference to the accompanying drawings. It is understood that the specific embodiments described here serve only to illustrate this disclosure and not to limit it. It should be noted that the accompanying drawings, for descriptive purposes, show only some, but not all, of the structures relevant to this disclosure.

Therefore, the features of the implementation fall within the scope of this disclosure regardless of the designations of the elements.

[0081] As in Fig. 1 and Fig. Figure 2 shows a hair removal device comprising a reflector 1, a light source 2, and a translucent body 3. The light source 2 is enclosed in the reflector 1 and can emit light. The reflector 1 can reflect the light emitted by the light source 2. The translucent body 3 has a light-incidence surface 31, which allows light to enter the interior of the translucent body 3, and a light-emission surface 32, which allows light to exit the interior of the translucent body 3. The light emitted by the light source 2 can be reflected by the reflector 1 and emitted uniformly from the light-emission surface 32 of the translucent body 3. Therefore, the uniformity of the light emitted can be improved, and the hair removal effect can be enhanced.

[0082] In some embodiments, the structures and relative positions of the light source 2, the reflector 1, and the translucent body 3 can satisfy the following conditions. The uniformity of the light-emitting surface 32 can be greater than or equal to 90%, or light spots on the light-emitting surface 32 can occupy at least 95% of the surface area. If the uniformity of the light-emitting surface 32 is greater than or equal to 90%, the hair removal effect of the hair removal device can be improved, allowing for the uniform removal of hair from the skin. Similarly, if the light spots on the light-emitting surface 32 occupy at least 95% of the surface area of ​​the light-emitting surface 32, the hair on the skin can be removed uniformly, and the utilization of the light can be improved.

[0083] If the light-emitting surface 32 of the hair removal device emits light less uniformly, or if the light spots occupy a relatively small area of ​​the light-emitting surface 32, the hair removal device may need to irradiate a position several times during use to remove the hair evenly, as otherwise the hair might not be removed evenly and the skin might not have a satisfactory appearance. With the structures and relative positions of the light source 2, the reflector 1, and the translucent body 3 in the present disclosure, the uniformity of the light-emitting surface 32 is greater than or equal to 90%, or the light spots occupy at least 95% of the area of ​​the light-emitting surface 32. In this way, the hair removal device does not need to irradiate a position several times.If the quality of the light source 2 and the power of the hair removal device are correctly configured, and the user's health is ensured, the hair removal device can irradiate a single area to efficiently and evenly remove the hair in that area. At the very least, the number of repeated irradiations of a single skin area can be reduced.

[0084] In some embodiments, the center point of the reflector 1, the center point of the light source 2, and the center point of the translucent body 3 can lie on a straight line. By adjusting the distance between the centers on this straight line, the uniformity of the light-emitting surface 32 can be greater than or equal to 90%, or the light spots can occupy at least 95% of the area of ​​the light-emitting surface 32. In some embodiments, the structures of the reflector 1, the light source 2, and the translucent body 3 can be adjusted so that the hair removal device fulfills the aforementioned characteristics.

[0085] In some embodiments, the structure of the reflector 1, the structure of the light source 2, and the structure of the translucent body 3 can each be specifically configured so that the hair removal device fulfills the aforementioned features. In some embodiments, the structures of the reflector 1, the light source 2, and the translucent body 3, as well as the relative positions of the reflector 1, the light source 2, and the translucent body 3, can be specifically configured so that the hair removal device fulfills the aforementioned features.

[0086] Furthermore, the hair removal device can also include a heat dissipation base 4 and a holder 5. The heat dissipation base 4 is configured to interact with the holder 5 to assemble the reflector 1 with the translucent body 3.

[0087] In some embodiments, such as in Fig. As shown in Figure 3, the hair removal device can further comprise a carbon-containing layer 91 arranged within the reflector 1. For example, the carbon-containing layer 91 can be located on the side of the reflector 1 facing away from the light source 2. The light source 2 can generate heat during use, and this heat can accumulate in the reflector 1. The carbon-containing layer 91 exhibits excellent thermal conductivity, thus increasing the heat conduction rate of the reflector 1 and improving its heat dissipation performance. This can prevent the hair removal device from being damaged by high temperatures and avoid irritating or injuring the user's skin.

[0088] In some embodiments, the carbon-containing layer 91 is arranged on the heat dissipation base 4. For example, the carbon-containing layer 91 can be arranged between the heat dissipation base 4 and the reflector 1 to accelerate the heat conduction rate between the heat dissipation base 4 and the reflector 1.

[0089] In some embodiments, the carbon-containing layer 91 can be arranged on an exposed surface of the heat dissipation base 4 to improve the heat dissipation performance of the heat dissipation base 4.

[0090] In some embodiments, the carbon-containing layer 91 can consist of graphene, graphite powders, a graphite foil, a graphite film and the like, and can be arranged at any available position as described in the present disclosure by plating, spraying, attaching, etc.

[0091] In some embodiments, the heat dissipation base 4 can be a ceramic base, which lowers the temperature inside the reflector 1. This allows the temperature of the reflector 1 to be controlled, thereby improving its performance and enabling it to reflect light more effectively. If the temperature inside the reflector 1 is not lowered, the high temperature can damage the light source 2 and reduce its lifespan. Furthermore, the heat can radiate to other components of the hair removal device, particularly those that come into contact with the skin. This high temperature can cause burns to the user's skin, potentially making the hair removal device uncomfortable to use.In the present disclosure, the ceramic base can lower the temperature inside the reflector 1, and the heat inside the reflector 1 can be dissipated by one or a combination of heat transfer, heat convection, and heat radiation. In this way, the temperature inside the reflector 1 can be lowered so that the heat from the light source 2 can be dissipated uniformly, and the heat dissipation efficiency of the hair removal device can be improved.

[0092] In some embodiments, a grooved body 41 is arranged on one side of the heat dissipation base 4. The grooved body 41 can be strip-shaped. The reflector 1 can be embedded in the grooved body 41. The bracket 5 defines a window 51. The window 51 can be square or any other shape, as long as the shape of the window 51 corresponds to a shape of the translucent body 3. The translucent body 3 can be embedded in the window 51. The translucent body 3 can be arranged on one side of the reflector 1, defining an opening. The heat dissipation base 4 and the bracket 5 can be detachably connected to each other so that the hair removal device can be easily assembled and disassembled.

[0093] In some embodiments, each of the two sides of the heat dissipation base 4 is provided with a first fastening section 42, and the first fastening section 42 and the heat dissipation base 4 can be formed as a single-piece structure. Each of the two sides of the bracket 5 is provided with a second fastening section 52, and the second fastening section 52 and the bracket 5 can be formed as a single-piece structure. The first fastening section 42 can correspond to the second fastening section 52. When connecting the heat dissipation base 4 to the bracket 5, the first fastening section 42 can be firmly attached to the second fastening section 52. In this way, the heat dissipation base 4 and the bracket 5 can be stably connected to each other, thereby improving the stability of the hair removal device.

[0094] In some embodiments, the first fastening section 42 can be a buckle block or a cantilever hook, and the second fastening section 52 can be an attachment hole. While the heat dissipation base 4 is connected to the bracket 5, the cantilever hook can be inserted into the attachment hole. Once the cantilever hook is inserted into the attachment hole, a wall of the attachment hole can confine the cantilever hook and prevent it from easily slipping out of the fastening hole. In this way, the first fastening section 42 and the second fastening section 52 can be stably connected to each other; that is, the heat dissipation base 4 and the bracket 5 can be fixed together, effectively preventing the heat dissipation base 4 from detaching from or falling off the bracket 5.

[0095] In some embodiments, the translucent body 3 can be a crystal.

[0096] As in Fig. 1, Fig. 2 and Fig. As shown in Figure 4, reflector 1 has a first reflective area 11 and a second reflective area 12. The first reflective area 11 is a curved area forming the base of the reflector 1, and the second reflective area 12 consists of two flat areas extending outwards from two ends of the curved area. The flat area may be tangential to the curved area. After the light source 2 emits light, reflector 1 reflects the light towards the translucent body 3.

[0097] In some embodiments, the reflector 1 can be a semicircular reflector. The light source 2 can be a strip lamp. The strip lamp emits light, and the curved area of ​​the reflector 1 can reflect the light towards the translucent body 3. Furthermore, the flat areas of the reflector 1 can also reflect light towards the translucent body 3. The light can be sufficiently reflected by both the curved and flat areas, thus improving the light emission rate and enhancing the utilization of the light.

[0098] In some embodiments, the reflector 1 can be strip-shaped.

[0099] As in Fig. As shown in Figure 5, in some embodiments the center of the light source 2 is arranged between a focal point of the reflector 1 and the base of the reflector 1. The light-incident surface 31 of the translucent body 3 is arranged between the light-emitting surface 32 and the focal point of the reflector 1. Furthermore, the light reflected by the reflector 1 can be focused to a position between the light-emitting surface 32 of the translucent body 3 and the focal point of the reflector 1. By configuring the positions of the light source 2, the reflector 1, and the translucent body 3, the uniformity of the light-emitting surface can be greater than or equal to 90%, or light spots on the light-emitting surface 32 can occupy at least 95% of the area of ​​the light-emitting surface 32.In this way, the light emitted by the light source 2 can be completely reflected by the reflector 1 to reach the translucent body 3, thereby improving the uniformity with which the translucent body 3 emits the light.

[0100] When the hair removal device is in operation, the light source 2 emits light, for example, whereby the first reflective area 11 and the second reflective areas 12 of the reflector 1 can reflect the light completely onto the translucent body 3. The light enters the translucent body 3 from the incident surface and then exits the translucent body 3 from the emitting surface, such that the uniformity of the emitting surface can be greater than or equal to 90%, or light spots on the emitting surface 32 can cover at least 95% of the area of ​​the emitting surface 32. In this way, the uniformity with which the hair removal device emits light can be improved, and the hair removal effect of the hair removal device can be enhanced.

[0101] In some embodiments, the angle between the flat area and a reference line can be between 5 and 20 degrees. The reference line can be a line between the center of the light source 2 and the center of the translucent body 3. By configuring the angle between the flat area and the reference line, the light can be completely reflected onto the translucent body 3. This reduces light waste and lowers operating costs. It also improves the uniformity with which the translucent body 3 emits light.

[0102] In a further embodiment of the hair removal device described in the present disclosure, the light source 2 is arranged near the base of the reflector 1, and the reflector 1 does not have a flat area that forms an angle between 5 and 20 degrees relative to the reference line. In this case, it is very likely that the light will be reflected multiple times. Due to the angle of incidence, the probability of multiple reflections of the light may be increased, and the angle of emission may be irregular and possibly difficult to control.

[0103] By defining the angle between the flat area and the reference line, a better light emission angle can be achieved when the light is emitted from reflector 1, and the light can be distributed more convergently. In this way, the light emission rate can be improved, effectively avoiding light losses and improving the light distribution.

[0104] Furthermore, the angle between the flat area and the reference line can be between 8 and 15 degrees. The angle between the flat area and the reference line can be 8 degrees. Alternatively, the angle between the flat area and the reference line can be 15 degrees. For example, the focal point can be closer in the aforementioned range. If the conditions regarding light uniformity and light utilization are met, the translucent body 3 can be positioned closer to the light source 2, allowing the hair removal device to have a more compact structure and saving material in its manufacture.

[0105] The angle between the flat area and the reference line can be between 8 and 15 degrees, allowing the focal point to be closer. This enables the translucent body 3 to be positioned closer to the light source 2, resulting in greater uniformity of light emission from the hair removal device. The uniformity of light emission can be improved by reconfiguring the device's structure without increasing the light intensity or other factors. In this configuration, the translucent body 3 is positioned closer to the light source 2. This allows the entire hair removal device to be smaller and more compact, making it easier to transport and use.

[0106] As in Fig. As shown in Figure 1, a side reflection element 13 is arranged at each of the two ends of the reflector 1 along a longitudinal direction of the reflector 1. The side reflection element 13 and the reflector 1 are formed as a single-piece structure. The side reflection element 13 is a plate and can reflect light exiting the two ends of the reflector 1 onto the translucent body 3. The side reflection element 13 defines a through-hole 131, and two side reflection elements 13 at the two ends can define two through-holes 131. The two through-holes 131 have a common center line. One end of the light source 2 passes through the through-hole 131.

[0107] In some embodiments, a fixing element 6 is connected to each of the two ends of the light source 2 to movably fix the light source 2 to the reflector 1. The fixing element 6 can be, for example, a soft silicone cover. Alternatively, the fixing element 6 can be a rubber cover. The fixing element 6 can be cylindrical. The fixing element 6 can define a mounting slot 61. Each of the two ends of the light source is embedded in the mounting slot 61. The fixing element 6 defines a fixing hole 62 along an axis of the fixing element 61. The fixing hole 62 communicates with the mounting slot 61. Each of the two ends of the light source is provided with a mounting post extending from the light source. The mounting post can extend through the fixing hole 62. The fixing element 6 can be arranged on an outer surface of the reflector 1.

[0108] In some embodiments, a support block 43 is arranged at each of the two ends of the heat dissipation base 4, and the support block 43 and the heat dissipation base 4 can be formed as a single-piece structure. The support block 43 defines a gap. Each of the two ends of the light source 2 and a corresponding fixing element 6 can be received in the gap. When the heat dissipation base 4 and the support block 43 are attached, the support block 43 and the bracket 5 can fix the fixing element 6, thus securing the light source 2 to the reflector 1. The fixing element 6 itself can be elastic. While the support block 43 and the bracket 43 fix the fixing element 6, the shape of the fixing element 6 can change accordingly when it is compressed to conform to the shape of the gap.Furthermore, the pressure exerted on the light source can be optimally reduced, thereby minimizing damage to the light source.

[0109] In some embodiments, a side wall of the bracket 5 near the fixing element 6 is provided with a limiting section 53 configured to define a position of the fixing element 6. The limiting section 53 can consist of spaced-apart projections or a notch. One wall of the notch may be curved. By configuring the limiting section 53, the support block 43 and the bracket 5 securely fix the fixing element 6, optimally preventing it from loosening and improving the stability of the hair removal device.

[0110] As in Fig. As shown in Figure 1, a filter 7, configured to filter the light, is arranged between the translucent body 3 and the reflector 1. The filter 7 is fixed to the bracket 5 and covers the window 51. When the filter 7 covers an opening of the reflector 1 facing the bracket 5, the filter 7 is further fixed relative to the heat dissipation base 4. When the heat dissipation base 4 is attached to the bracket 5, one side wall of the bracket 5, near the reflector 1, rests against one side of the filter 7, and another side of the filter 7 rests against the reflector 1. The filter 7 can filter out harmful UV light, thus reducing damage to the human body, which can improve the safety of the hair removal device and enhance the hair removal effect.

[0111] In some embodiments, a pad 8 is arranged between the bracket 5 and the filter 7. The shape of the pad 8 can resemble the shape of the filter 7. The pad 8 can be leaf-shaped and define a clearance opening 81 through which light can pass. The size of the clearance opening 81 is smaller than the size of a side wall of the translucent body 3 facing the pad 8. When the heat dissipation base 4 is attached to the bracket 5, the translucent body 3 rests against one side of the pad 8, and the other side of the pad 8 rests against the filter 7. The pad 8 can reduce the pressure exerted by the translucent body 3 on the filter 7 and minimize collisions between the translucent body 3 and the filter 7. In this way, production costs can be optimally reduced and the service life of the filter 7 increased.

[0112] As in Fig. 11 and Fig. As shown in Figure 12, in another embodiment of the hair removal device, an elastic sealing ring 16 is arranged between the filter 7 and the translucent body 3. The elastic sealing ring 16 can be annular. The filter 7 and the translucent body 3 can be sealed with the elastic sealing ring 16. In this way, no condensation can form between the translucent body 3 and the filter 7. Dirt cannot penetrate the connection between the translucent body 3 and the filter 7. The elastic sealing ring 16 is preferably annular.

[0113] If the hair removal device falls to the ground, the translucent body 3 can, of course, collide hard with the ground. A conventional translucent body 3 can transmit an impact to the filter 7 in such a way that the filter 7, the reflector 1, and the light source 2 may vibrate and be damaged. In the hair removal device of the present embodiment, the impact force can be eliminated by the elastic sealing ring 16 if the translucent body 3 is subjected to an impact. Due to the elasticity of the elastic sealing ring 16, it can deform elastically under pressure from external forces, thereby reducing or eliminating the impact between the filter 7 and the translucent body 3 and reducing the likelihood of the filter 7, the reflector 1, and the light source 2 being damaged by the impact force.Therefore, the collision protection performance of the hair removal device can be improved.

[0114] As in the Fig. As shown in Figures 13 to 15, the elastic sealing ring 16 has an inner ring 161 that transmits light. After being filtered by the filter 7, the light can be guided through the inner ring 161 to the translucent body 3 and then shine onto the user's skin.

[0115] In the present embodiment, the filter 7 and the translucent body 3 can be fixed directly to the holder 5. The filter 7 and the translucent body 3 cannot move relative to the holder 5. Therefore, during use of the hair removal device, it is prevented that the translucent body 3 moves backward relative to the holder 5 due to a human bone or a sharp object striking it, and that the filter 7 or a hair removal assembly 100 is irreparably deformed by compression. The elastic sealing ring 16 can be irreparably deformed by repeated compression. In this way, the light transmission efficiency of the hair removal device is not impaired, and a waste of light energy is avoided.

[0116] The elastic sealing ring 16 further defines a mounting groove 162, which communicates with an opening in the inner ring 161. The mounting groove 162 is defined on a side of the elastic sealing ring 16 facing away from the hair removal device 100. The inner ring 161 extends from a bottom wall of the mounting groove 162 to the filter 7. The translucent body 3 is partially received in the mounting groove 162 to improve the sealing effect between the translucent body 3 and the elastic sealing ring 16 and to fix the elastic sealing ring 16 to the translucent body 3, thus achieving a secure connection between the elastic sealing ring 16 and the translucent body 3.

[0117] In some embodiments, the elastic sealing ring 16 can have an outer ring 163 and a projection 164 located on one side of the outer ring 163. The projection 164 can abut the filter 7. One side of the outer ring 163 facing away from the projection 164 defines the mounting groove 162. The inner ring 161 extends from the bottom wall of the mounting groove 162 to the projection 164. Both the outer ring 163 and the projection 164 can have a fully closed loop structure. Light within the inner ring 161 can only escape outwards from the transparent body 3.

[0118] In some embodiments, the cross-section of the projection 164 can be a transversely oriented triangle. The contact area between the projection 164 and the filter 7 can be smaller than the contact area between the projection 164 and the outer ring 163. Therefore, when the elastic sealing ring 16 is present, the end of the projection 164 facing away from the outer ring 163 can be partially corrugated after compression. Since the elastic sealing ring 16 is elastic, a corrugated portion of the elastic sealing ring 16 can bear firmly against the filter 7. That is, if the distance between the translucent body 3 and the filter 7 changes slightly, the elastic sealing ring 16 can be adjusted by designing the corrugated portion to accommodate the change in distance.In this way, a tight fit or even an interference fit can be maintained at all times between the elastic sealing ring 16 and the translucent body 3, as well as between the elastic sealing ring 16 and the filter, thereby achieving a better sealing effect. In other embodiments, the cross-section of the projection 164 can be trapezoidal.

[0119] In the present embodiment, the elastic sealing ring 16 can be a ring made of a laser-resistant, high-temperature-resistant and low-temperature-resistant material, so that when using the elastic sealing ring 16, it can be prevented that the elastic sealing ring 16 deforms due to high or low temperatures or laser irradiation, thereby increasing the service life of the elastic sealing ring 16.

[0120] According to the present disclosure, a hair removal device is provided. The hair removal device can comprise the reflector 1, the light source 2, and the translucent body 3. The light source 2 emits light, and the light emitted by the light source 2 can be reflected by the reflector 1, allowing the light to enter the translucent body 3 from the light-incidence surface 31 and exit the translucent body 3 from the light-emitting surface 32. Furthermore, the structures and relative positions of the light source 2, the reflector 1, and the translucent body 3 can satisfy the following conditions: The uniformity of the light-emitting surface can be greater than or equal to 90%, or light spots on the light-emitting surface 32 can occupy at least 95% of the area of ​​the light-emitting surface 32.By configuring the structures and relative positions of the light source 2, the reflector 1 and the translucent body 3, the light can be emitted uniformly from the light emission surface 32 of the translucent body 3, so that the uniformity with which the hair removal device emits the light can be improved and the hair removal effect of the device can be improved.

[0121] As in Fig. 5 shown, is Fig. Figure 5 shows a schematic structural view of the hair removal device according to a further embodiment of the present disclosure. The hair removal device can have a head section 111 and a hand section 112 connected to the head section 111. The head section 111 is provided with a cold-compression section 1111, which is configured to be attached to the skin. The cold-compression section 1111 can emit light to irradiate a hair follicle in the skin. The light can penetrate the skin to irradiate the hair follicle and remove the hair. In addition, the cold-compression section 1111 can rapidly cool the skin to reduce burns from the light. In this way, the user does not experience any discomfort during the use of the hair removal device.In some embodiments, the cold compression section 1111 can emit light for skin care in such a way that the hair removal device can simultaneously remove hair and perform skin care.

[0122] In some embodiments, the hand section 112 may have a housing that defines a space in the center (not marked in the drawings). A surface of the housing may define a vent opening 1211. The vent opening 1211 may be connected to an interior and an exterior of the housing, allowing the hair removal device to exchange air with the outside environment via the vent opening 1211 and thus lowering the temperature inside the device. The housing may further include an interface 1212 configured for connection to an external power supply for charging the hair removal device. The present disclosure does not limit the position of the interface 1212 on the housing.

[0123] As in Fig. 6 and Fig. 7 shown, is Fig. 7 An exploded view of the device according to one embodiment of the present disclosure. An arrow in Fig. Figure 7 shows the direction of airflow within the hair removal device, which is driven by a cold drive assembly. A straight line represents the direction in which cold air flows, and a wavy line represents the direction in which hot air flows. Specifically, the hair removal device may comprise the housing, a light cover 113 arranged over an opening in the housing, a hair removal mechanism 14 housed within the housing, and a bottom cover 15.

[0124] In the present embodiment, the housing can comprise a first housing 121 and a second housing 122. The first housing 121 and the second housing 122 can be interlocked to define a cavity and two openings at two ends of the housing. The hair removal mechanism 14 is accommodated in the cavity, and the light cover 113 and the bottom cover 15 are arranged to cover the two openings, respectively, to close the openings defined by the first housing 121 and the second housing 122 after the first housing 121 and the second housing 122 have been interlocked to define the cavity.

[0125] In some embodiments, the first housing 121, the second housing 122, the light cover 113 and the bottom cover 15 can be connected by snap fasteners, screws, adhesives, etc.

[0126] The hair removal mechanism 14 can include the hair removal assembly 100, a cold compression assembly 200, a heat dissipation base 300 and the cold drive assembly 400.

[0127] The cold compression assembly 200 is located near the light cover 113. The light cover 113 may have a through-hole (not marked in the drawings). A portion of the cold compression assembly 200 is exposed through the through-hole in the light cover 113 to come into direct contact with the skin. It is understood that this portion of the cold compression assembly 200 and the light cover 113 together form the head section 111 of the hair removal device.

[0128] The hair removal assembly 100 is located on one side of the cold compression assembly 200, facing away from the light cover 113, and is configured to emit light to the cold compression assembly 200. The light can be visible light, such as red, green, or yellow light. Once the light enters the cold compression assembly 200, it can pass through it to penetrate further into the skin and reach the hair follicles beneath the skin to remove hair.

[0129] The heat dissipation base 300 is arranged on one side of the cold compression assembly 200 and connected to it. When applied to the skin, the cold compression assembly 200 absorbs heat from the skin to lower the skin temperature and reduce burning. With prolonged use, the temperature of the cold compression assembly 200 can increase, potentially reducing its cooling effect. The heat dissipation base 300 absorbs this heat, allowing the cold compression assembly 200 to continue operating at a lower temperature, thus ensuring that the cold compression assembly 200 continues to cool the skin. Therefore, in this embodiment, the hair removal device can operate continuously at a low temperature, preventing injury to the user.

[0130] The cooling drive assembly 400 is arranged on one side of at least one part of the heat dissipation base 300 facing away from the hair removal assembly 100, and is configured to dissipate heat from the hair removal assembly 100 and the heat dissipation base 300.

[0131] In the present embodiment, the cooling drive assembly 400 can absorb an external cooling medium that passes through the vent opening 1211 and enters the interior of the hair removal device. The cooling medium can flow along the hair removal device 100 and the heat dissipation base 300 to dissipate heat and then exit the device through the vent opening 1211.

[0132] In some embodiments, the external cooling medium can be air. The cooling drive assembly 400 can draw in the air and blow it towards the hair removal device 100 and the heat dissipation base 300. The heat from the hair removal device 100 and the heat dissipation base 300 can be dissipated by the airflow.

[0133] In the present embodiment, the vent opening 1211 can be defined in the first housing 121, and at least a part of the refrigeration drive assembly 400 is arranged opposite the vent opening 1211, so that the refrigeration drive assembly 400 can better absorb the external cooling medium entering the housing through the vent opening 1211 and the heat dissipation efficiency can be improved. In other embodiments, the vent opening 1211 can be defined in the second housing 122.

[0134] As in Fig. 7 and Fig. 8 shown, is Fig. 8 an exploded view of the in Fig. Structure shown in 7, where the arrows point in Fig. 8 can indicate the direction in which air is blown out of a fan.

[0135] In the present embodiment, the hair removal device can further comprise a holder 500, a circuit board 600, a processor 700, and a capacitor 800. The hair removal assembly 100 and the cold compression assembly 200 can be arranged within the holder 500, and the cold drive assembly 400 can be arranged adjacent to the holder 500. The hair removal assembly 100, the cold compression assembly 200, and the cold drive assembly 400 can be mounted on the circuit board 600 and electrically connected to it.

[0136] The processor 700 and the capacitor 800 can be electrically connected to and mounted on the circuit board 600. When an external power supply is connected, it can charge the capacitor 800, which can then power the hair removal device. Furthermore, the capacitor 800 can store energy when connected to the external power supply, allowing the hair removal device to be used even without a connection. The processor 700 can send control commands to the hair removal assembly 100, the cold compression assembly 200, and the cold drive assembly 400 to control the operation of the hair removal device. For example, the hair removal device can be switched on and off, its thermal protection can be controlled, its power output can be adjusted, and so on.

[0137] In the present embodiment, the printed circuit board 600 can be fixed in the second housing 122, and the printed circuit board 600 can be a PCBA printed circuit board.

[0138] In the prior art, the heat inside the hair removal device can continuously increase during use. Circuits and components inside the hair removal device can explode, burn out, short-circuit, etc., when operating at high temperatures. In the present embodiment, the cooling drive assembly 400 can dissipate heat from the hair removal assembly 100 and the heat dissipation base 300, and the heat dissipation base 300 can dissipate heat from the cold compression assembly 200, so that the cold compression assembly 200 can compress the skin to cool it, making the skin feel comfortable and preventing the components from exploding, burning out, short-circuiting, etc.

[0139] Specifically, the hair removal device 100 can comprise a light source 101, a reflector 102, a filter 103 and two electrodes 104.

[0140] The light source 101, the reflector 102, and the filter 103 are arranged within the holder 500; that is, the holder 500 is configured with mounting positions for the light source 101, the reflector 102, and the filter 103. The light source 101, the reflector 102, and the filter 103 can be snapped into the mounting positions in the holder 500 accordingly.

[0141] The light source 101 can be positioned opposite the cold compression assembly 200. The light emitted by the light source 101 can be directed into the cold compression assembly 200. The reflector 102 can be positioned on the side of the light source 101 facing away from the cold compression assembly 200 and can reflect the light from the light source 101 into the cold compression assembly 200 to prevent loss of light energy. The filter 103 is positioned between the light source 101 and the cold compression assembly 200. That is, the light source 101, the filter 103, and the cold compression assembly 200 can be arranged sequentially in the direction of light propagation. The filter 103 is configured to filter out a harmful portion of the light emitted by the light source 101, thus reducing light-induced skin damage and increasing the safety of hair removal.The two electrodes 104 can be connected to two sides of the light source 101 and electrically connected to the circuit board 600 to transmit electrical signals.

[0142] In some embodiments, the light source 101 can be a lamp, and the color of the light emitted by the lamp is not limited. The lamp can emit colored light, composite light, etc. The wavelength and frequency of the light can be set as required. The type of lamp is not limited. The lamp can be a xenon semiconductor lamp, a quartz lamp, a laser lamp, etc. The type of light can be intense pulsed light (IPL), deep pulsed light (DPL), optimal pulse technology (OPT), advanced optimal pulse technology (AOPT), broadband light (BBL), etc. The type of light can be determined based on the desired effects.

[0143] In some embodiments, the reflector 102 can be a U-shaped reflector surrounding the light source 101. Furthermore, an opening of the U-shaped reflector can face the cold compression assembly 200 and reflect light that does not enter the cold compression assembly 200 back to it. In addition, the reflector 102 can prevent the heat generated by the light source 101 from being transferred to other components of the hair removal device. In the present embodiment, the holder 500 can have a fixing frame 550 and a tube 560. The fixing frame 550 can define a first receiving space 510 and a second receiving space 520. The first receiving space 510 is configured to receive the hair removal assembly 100. The second receiving space 520 is configured to receive the cold compression assembly 200.The first recording chamber 510 can be adjacent to the second recording chamber 520 to reduce the distance between the hair removal device 100 and the cold compression assembly 200, thereby reducing the loss of light emitted by the hair removal device 100. The second recording chamber 520 can be located closer to the head section 111 of the [unit / device]. Fig. The hair removal device shown in Figure 6 is located in the first receiving chamber 510. When the hair removal device is in operation, the light source 101 can generate a large amount of heat, which can irradiate the reflector 102 and the filter 103, thus increasing their temperature. Therefore, the heat from the light source 101, the reflector 102, and the filter 103 must be dissipated.

[0144] In the present embodiment, the bracket 500 can comprise the fixing frame 550 and a tube 560. One end of the tube 560 can be connected to one side of the fixing frame 550, and the other end of the tube 560 can extend toward the refrigeration drive assembly 400. The fixing frame 550 defines an air outlet 540 that communicates with the first receiving chamber 510, and the tube 560 defines an air inlet 530 that communicates with the first receiving chamber 510. The air inlet 530, the first receiving chamber 510, and the air outlet 540 can be sequentially connected to one another.

[0145] The air inlet 530 can be connected to the refrigeration drive assembly 400. The air outlet 540 can be connected to the vent 1211. The refrigeration drive assembly 400 can draw in outside air from the vent 1211 and blow the air towards the air outlet 540. The air enters the first receiving chamber 510 through the air outlet 540 and carries away heat from the light source 101, the reflector 102, and the filter 103 in the first receiving chamber 510. Furthermore, the air can flow out of the device through the air outlet 540 and the vent 1211 to dissipate the heat.

[0146] In some embodiments, part of the fixing frame 550 and part of the tube 560 form a first support 501, and the remaining part of the fixing frame 550 and the remaining part of the tube 560 form a second support 502. In other embodiments, the fixing support 550 can be designed as a one-piece structure.

[0147] The first bracket 501 and the second bracket 502 can be connected to each other via a snap-fit ​​connection. The first bracket 501 can be located near the first housing 121, and the second bracket 502 can be located near the second housing 122. The air outlet 540 can be defined in the first bracket 501 and can be located opposite the vent 1211 in the first housing 1211 to increase the heat dissipation efficiency at the air outlet 540. The first receiving chamber 510 can be defined in a portion of the first bracket 501 and a portion of the second bracket 502. This portion of the first bracket 501 and the portion of the second bracket 502 can correspond to the fixing frame 550 and snap together. The air inlet 530 can be defined in another portion of the first bracket 501 and another portion of the second bracket 502.The other part of the first bracket 501 and the other part of the second bracket 502 can correspond to the tube 550 and be interlocked together. The air inlet 530 can be connected to the first receiving chamber 510 and to the refrigeration drive assembly 400. An interior of the bracket 5 can define a channel for directing an airflow, thereby directing the airflow from the refrigeration drive assembly 400 into the first receiving chamber 510.

[0148] Therefore, in the present embodiment, the hair removal assembly 100 can dissipate heat via the cooling drive assembly 400, thus ensuring that the hair removal device can be used safely.

[0149] Furthermore, in the present embodiment, the cold compression assembly 200 can have a translucent body 202 and a cooling element 201.

[0150] The translucent body 202 can be configured to be attached to the skin. The translucent body 202 can face the light source 101. The translucent body 3 can be an element that transmits light. The light emitted by the light source 101 enters the translucent body 202 and passes through it to reach the skin.

[0151] In some embodiments, the translucent body 202 can be a light-conducting crystal, such as sapphire, K9 glass, or crystal glass. If the translucent body 202 is made of sapphire, it can exhibit excellent thermal conductivity.

[0152] In some embodiments, the translucent body 202 can be cylindrical or cuboid. A surface of the translucent body 202 facing away from the light source 101 can be configured so that it can be attached to the skin.

[0153] The cooling element 201 can be connected to the translucent body 202 to absorb heat from it. Since the temperature of the translucent body 202 increases when it comes into contact with the skin, the cooling element 201 can absorb this heat, keeping the body 202 cool. If the body 202 remains in contact with the skin for an extended period, it can continue to cool the skin, thus reducing any burning sensation.

[0154] Furthermore, the cooling element 201 can be a semiconductor cooling element. One end of the cooling element 201, which absorbs heat, can be connected to the translucent body 202, and the other end of the cooling element 201 can dissipate the heat.

[0155] In order to dissipate heat from the heat dissipation end of the cooling element 201, in the present embodiment the heat dissipation base 300 is connected to a heat absorption end of the cooling element 201 and absorbs the heat from the cooling element 201.

[0156] Specifically, the heat dissipation base 300 can comprise a heat dissipation plate 301 and a heat dissipation wing 302. One surface of the heat dissipation plate 301 has a first region 310 and a second region 311, which are arranged side by side. The hair removal assembly 100 is arranged in the first region 310, and the heat dissipation wing 302 is arranged in the second region 311. The second region 311 is arranged on one side of the fixing frame 550, which is connected to the tube 560. The heat dissipation wing 302 and the tube 560 are arranged side by side on one side of the fixing frame. The fixing frame 550 is arranged in the first region 310. The heat dissipation plate 301 is arranged on the circuit board 600 and connected to the cold compression assembly 200. Specifically, the heat dissipation element 201 can be connected to the heat dissipation plate 301 by means of a thermally conductive silicone grease.The cold compression assembly 200 can quickly transfer heat to the heat dissipation plate 301 via the thermally conductive silicone grease. The heat dissipation vane 302 can dissipate heat from the heat dissipation plate 301 and assist the heat dissipation plate 301 in its heat dissipation, so that the heat dissipation plate 301 can continuously absorb heat from the cooling element 201.

[0157] In some embodiments, the number of heat dissipation wings 302 can be more than one. The additional heat dissipation wings 302 can be parallel to each other and attached to the heat dissipation plate 301 by welding.

[0158] In some embodiments, a surface of the heat dissipation wing 302 can be sprayed with a thermally conductive coating. The thermally conductive coating can emit radiation to dissipate heat from the heat dissipation wing 302 and can prevent the heat dissipation wing 302 from being affected, corroded, and worn by water.

[0159] In the present embodiment, the heat dissipation plate 301 can be a temperature-homogeneous plate. When a liquid within the temperature-homogeneous plate comes into contact with a high-temperature environment, the liquid can absorb heat and evaporate into a gas. When the gas comes into contact with a low-temperature environment, the gas can release heat and condense back into a liquid. Therefore, the temperature of a surface of the temperature-homogeneous plate can be kept homogeneous due to periodic evaporation and condensation. Thus, part of the surface of the heat dissipation plate 301 is connected to the cooling element 201, and the other part is connected to the heat dissipation vane 302, so that the heat generated by the cooling element 201 can be dissipated via the heat dissipation plate 301 and the heat dissipation vane 302.

[0160] In some embodiments, the carbon-containing layer can be arranged between the translucent body 202 and the heat dissipation base 300, for example on a surface of the heat dissipation plate 301 that is thermally coupled to the translucent body 202. The carbon-containing layer exhibits excellent thermal conductivity and can accelerate the heat conduction rate of the heat dissipation plate 301 and improve the heat dissipation performance of the heat dissipation base 300.

[0161] In some embodiments, the carbon-containing layer can be a graphene material, graphite powder, a graphite foil, or a graphite film.

[0162] In some embodiments, the carbon-containing layer can be arranged by plating, spraying, or bonding.

[0163] To improve the heat dissipation performance of the heat dissipation base 300, the heat dissipation base 300 can also be connected to the refrigeration drive assembly 400 in the present embodiment.

[0164] Specifically, the heat dissipation vane 302 of the heat dissipation base 300 can be connected to the cooling drive assembly 400. The cooling drive assembly 400 can draw in outside air through the vent opening 1211 and force the air to flow towards the heat dissipation vane 302. The air can then flow along the heat dissipation vane 302 to dissipate heat from it.

[0165] In one example, the heat dissipation vane 302 can be arranged parallel to an airflow direction driven by the refrigeration drive assembly 400 in order to increase a contact area between the heat dissipation vane 302 and the airflow and thus increase the efficiency of heat dissipation from the heat dissipation vane 302.

[0166] The heat dissipation vane 302 can face the vent opening 1211 in the first housing 121. After flowing along the heat dissipation vane 302, the airflow can quickly exit the device through the vent opening 1211.

[0167] Therefore, the cooling drive assembly 400 of the present embodiment can drive the cooling medium to dissipate heat from the hair removal assembly 100 and can further dissipate heat from the heat dissipation base 300. With improved safety, the irradiated skin can be compressed for cooling, and the risk of skin burns can be reduced. Furthermore, the cooling compression assembly 200 can be controlled by the heat dissipation base 300 and the cooling drive assembly 400 to reach a low temperature of approximately zero degrees. In this way, the skin near a light exit aperture can approach the freezing point extremely closely, the burning sensation on the skin can be reduced, and brief contact between the skin and the device cannot cause skin damage.

[0168] As in Fig. 7, Fig. 8 and Fig. 10 shown, is Fig. 10 A structural schematic view of an air outlet of a fan housing of the in Fig. 8. In the present embodiment, the refrigeration drive assembly 400 can comprise a fan housing 401 and a fan 402. The fan housing 401 is arranged on one side of the heat dissipation base 300 that faces away from the refrigeration compression assembly 200, and the fan 402 is accommodated within the fan housing 401.

[0169] An air inlet end of the fan 402 faces the vent opening 1211 in the first housing 121. The fan 402 drives the outside air to flow through the vent opening 1211 into the fan 402. The fan housing 401 defines an air outlet 410 for discharging air. An air outlet end of the fan 402 is connected to the air outlet 410. The fan 402 drives the outside air to flow through the vent opening 1211 into the fan 402 and further drives the air to flow out through the air outlet 410.

[0170] In some embodiments, the fan 402 can be a radial fan, an axial fan, a mixed-flow fan or a cross-flow fan.

[0171] Furthermore, the air outlet 410 can have a first air outlet 411 and a second air outlet 412. The air at the air outlet 410 of the fan 402 can be divided into two parts. One of the two parts of the air flows out of the device through the first air outlet 411, and the other part of the air flows out of the device through the second air outlet 412.

[0172] In some embodiments, the air outlet 410 may further comprise a third air outlet or multiple air outlets. The present disclosure does not limit the number of air outlets.

[0173] In the present embodiment, the first air outlet 411 is connected to the air inlet 530 of the bracket 500. The fan 402 drives the outside air to flow into the fan 402 through the vent 1211. The fan 402 drives the air to flow from the first air outlet 411 and the air inlet 530 into the first receiving chamber 510. The air in the first receiving chamber 510 can dissipate heat from the light source 101, the reflector 102, and the filter 103. Finally, the air flows out of the device through the air outlet 540 and the vent 1211. In this way, the heat is dissipated to the outside, thus dissipating the heat from the hair removal device 100.

[0174] In the present embodiment, the second air outlet 412 is connected to the heat dissipation vane 302 of the heat dissipation base 300. The fan 402 drives the outside air so that it enters the fan 402 from the vent opening 1211. The fan 402 drives the air to flow through the second air outlet 412 between each pair of the multiple heat dissipation vanes 302 of the heat dissipation base 300. The air flows along the heat dissipation vanes 302, conducts the heat away from the heat dissipation vanes 302, and then flows out of the device through the air outlet 1211. Once the temperatures of the heat dissipation vanes 302 have decreased, the heat of the heat dissipation plate 301 can be reduced accordingly. In this way, the heat dissipation plate 301 can absorb the heat from the cold compression assembly 200, thereby dissipating the heat from the cold compression assembly 200.

[0175] In some embodiments, the amount of air flowing through the first air outlet 411 and the second air outlet 412 is not limited and can be determined according to requirements. The amount of air flowing through the first air outlet 411 and the second air outlet 412 can be controlled by configuring the size of the first air outlet 411 and the size of the second air outlet 412. For example, in the present embodiment, the air outlet area of ​​the second air outlet 412 is larger than the air outlet area of ​​the first air outlet 411, so that a larger volume of air flows through the second air outlet 412 to improve the efficiency of heat dissipation from the heat dissipation plate 301.

[0176] According to the embodiments described above, in the hair removal device of the present embodiment, the heat from the hair removal assembly 100, the cold compression assembly 200, and the heat dissipation base 300 can be dissipated by the cold drive assembly 400, so that the heat from the hair removal assembly 100 and the cold compression assembly 200 can be dissipated simultaneously. This improves the heat dissipation performance and enhances the safety of the hair removal device. Furthermore, the skin can be compressed for continuous cooling, and the skin temperature can be allowed to approach freezing point indefinitely, thus reducing the burning sensation and protecting the skin from damage during hair removal.

[0177] As in Fig. 16 and Fig. As shown in Figure 17, a hair removal device is provided in the present disclosure. The hair removal device can comprise the reflector 1, the light source 2, a first transparent body 3, a heat dissipation base 4, and a cooling element 5. The light source 2 is arranged inside the reflector 1 and configured to emit light. The reflector 1 can reflect the light. The first transparent body 3 is arranged on and covers a light-emitting side of the reflector 1. Furthermore, the first transparent body 3 and the reflector 1 together form a cavity for receiving the light source 2. The reflector 1 is embedded in a heat dissipation base 4. One side of the heat dissipation base 4, which is in contact with the reflector 1, is thermally coupled to the reflector 1. The cooling element 5 is arranged on the heat dissipation base 4.One cooling side of the cooling element 5 is thermally coupled to the side of the heat dissipation base 4 that is in contact with the cooling element 5. A body of the light source 2 can be suspended in the cavity, and the cooling element 5 is configured to cool the cavity.

[0178] While the hair removal device is in operation, the light source 2 emits a large amount of light within the reflector 1, and the heat generated by this light can accumulate in the cavity. Furthermore, the temperature of the reflector 1 can increase as the heat accumulates in the cavity. One side of the heat dissipation base 4 is thermally coupled to the reflector 1, and the other side of the heat dissipation base 4 is thermally coupled to the cooling element 5. This thermal coupling can be achieved through any combination of heat transfer, thermal convection, and thermal radiation. That is, the heat from the reflector 1 can be dissipated via the heat dissipation base 4, and the heat in the cavity can be dissipated, thus cooling the reflector 1 and the cavity and improving the efficiency of heat dissipation from the light source 2.By configuring the body of the light source 2, which is suspended in the cavity, the heat from the light source 2 can be dissipated more evenly, and its service life can be improved. Specifically, the heat generated during operation of the light source 2 can be dissipated by radiation in all directions. Furthermore, the air is distributed evenly around the light source 2, ensuring complete contact with it and allowing for uniform heat dissipation. The heat generated by the light source 2 can be transferred through the cavity to the reflector 1 and the first translucent body 3, and then dissipated from the device.

[0179] Furthermore, the cooling element 5 can further dissipate heat from the heat dissipation base 4 to achieve rapid heat dissipation and improve the heat dissipation effect of the hair removal device. Additionally, heat radiation from the cavity to other components of the hair removal device can be reduced. In this way, the burning sensation on the skin being treated during use of the hair removal device can be reduced, thereby improving the performance of the device.

[0180] In some embodiments, the hair removal device may further include the carbon-containing layer arranged in the reflector 1. For example, as shown in Fig. As shown in Figure 18, the carbon-containing layer 91 is arranged on one side of the reflector 1, facing away from the reflector 2. The light source 2 can generate heat during use, which can be collected in the reflector 1. The carbon-containing layer 91 has excellent thermal conductivity, which can increase the heat conduction rate of the reflector 1 and improve its heat dissipation performance, thus preventing the hair removal device from being damaged due to high temperature and preventing irritation or damage to the user's skin.

[0181] In some embodiments, the carbon-containing layer is arranged on the heat dissipation base 4. For example, in Fig. As shown in Figure 18, the carbon-containing layer can be arranged between the heat dissipation base 4 and the reflector 1, thereby increasing the heat conduction rate between the heat dissipation base 4 and the reflector 1.

[0182] In some embodiments, the carbon-containing layer can be arranged on the side of the cooling element 5 facing the heat dissipation base 4, or on an exposed surface of the cooling element 5, to improve the cooling effect of the cooling element 5. In this way, the heat from the heat dissipation base 4 can be dissipated quickly and efficiently, thus allowing the heat from the reflector 1 to be dissipated rapidly.

[0183] In some embodiments, the carbon-containing layer can be the graphene material, graphite powder, graphite foil or graphite film and can be arranged at any available position as described in the present disclosure by plating, spraying or attaching.

[0184] In some embodiments, the heat dissipation base 4 can be made of ceramic or aluminum. The heat dissipation base 4 can be configured to quickly dissipate heat from the reflector 1, thereby improving the reflector's heat dissipation efficiency. For example, ceramics exhibit stable physical properties such as corrosion resistance and low thermal expansion. Furthermore, ceramics absorb heat rapidly. Therefore, the ceramic base can quickly absorb heat, and the reflector 1 and the cavity can be cooled by the ceramic base, thus improving the heat dissipation efficiency of the hair removal device.

[0185] Furthermore, the ceramic is an insulator. A short circuit cannot occur when the ceramic comes into contact with the reflector 1. The ceramic base covers an outer surface of the reflector 1, thus reducing the risk of current loss at the device's reflector 1 and improving the safety of the hair removal device. The body of the light source 2 is suspended in the cavity and spaced apart from the reflector, which can be a conductor. When the device is powered on, a strong electric field is formed between the light source 2 and the reflector 1, causing the light source 2 to emit light.

[0186] One side of the ceramic base is provided with a grooved body 41. The grooved body 41 can be strip-shaped. In some embodiments, the reflector 1 can be a semicircular reflector. The reflector 1 can be embedded in the grooved body 41. The first translucent body 3 can be a filter or a transparent glass carrier. The first translucent body 3 can be fixed relative to the ceramic base. The heat generated by the light source 2 can be confined within the cavity by the first translucent body 3 and the reflector 1, thereby reducing the possibility of the heat being radiated to other components of the hair removal device.In the present embodiment, the ceramic base is arranged with the groove body 41, and the reflector 1 is embedded in the groove body 41, so that the contact area between the ceramic base and the reflector 1 can be increased, thereby increasing the ability of the ceramic base to absorb heat from the reflector 1 and improving the heat dissipation efficiency of the reflector 1 and the cavity.

[0187] In some embodiments, the reflector 1 can be a strip-shaped reflector.

[0188] As in Fig. As shown in Figure 16, the cooling element 5 can be a TEC cooling plate or a cooling block in some embodiments. The cooling element 5 is configured to cool the heat dissipation base 4 in order to dissipate heat from the heat dissipation base 4 quickly and efficiently, so that the heat from the reflector 1 can be dissipated rapidly. In the present embodiment, the cooling element 5 is the TEC cooling plate, which is shown for illustrative purposes only. The present disclosure does not restrict the detailed structure of the cooling element 5.

[0189] In some embodiments, the heat dissipation base 4 can be strip-shaped. The TEC cooling plate can also be strip-shaped. The heat dissipation base 4 has a mounting slot. This slot is located on the side of the heat dissipation base 4 facing away from the opening of the reflector 1. The TEC cooling plate is inserted into the mounting slot. The TEC cooling plate is in sufficient contact with the heat dissipation base 4. The TEC cooling plate quickly dissipates the heat transferred from the cavity and the reflector 1 to the heat dissipation base 4, thus cooling the heat dissipation base 4. In this way, the light source 2 is better protected during operation of the hair removal device, and damage to the light source 2 caused by high temperatures is effectively reduced, thereby extending the service life of the light source 2.On the other hand, the temperature of an outer surface of the hair removal device can be lowered so that the user can comfortably hold the hair removal device in their hand, which improves the performance of the hair removal device.

[0190] As in Fig. 16, Fig. 17 and Fig. As shown in Figure 19, the hair removal device has a bracket 6. The bracket 6 is configured to interact with the heat dissipation base 4 to assemble the reflector 1 with the first translucent body 3. The bracket 6 defines a window 61. The window 61 can be square or rectangular. The first translucent body 3 is fixed to the bracket 6 and covers the window 61. The heat dissipation base 4 and the bracket 6 can be detachably connected to each other, allowing the hair removal device to be easily assembled and disassembled. The reflector 1 and the first translucent body 3 can be fixed to each other by the heat dissipation base 4 and the bracket 6.In this way, the components inside the hair removal device can be arranged more compactly, saving internal space, allowing the device to be designed efficiently, and making the device easy to use.

[0191] In some embodiments, each of the two sides of the heat dissipation base 4 is provided with a first fastening section 42, and the first fastening section 42 and the heat dissipation base 4 can be formed as a single-piece structure. Each of the two sides of the bracket 6 is provided with a second fastening section 62, and the second fastening section 62 and the bracket 6 can be formed as a single-piece structure. The first fastening section 42 can correspond to the second fastening section 62. When connecting the heat dissipation base 4 to the bracket 6, the first fastening section 42 can be firmly attached to the second fastening section 62. In this way, the heat dissipation base 4 and the bracket 6 can be stably connected to each other, thereby improving the stability of the hair removal device.

[0192] In some embodiments, the first fastening section 42 can be a buckle block or a cantilever hook, and the second fastening section 62 can be a fixing hole. When connecting the heat dissipation base 4 to the bracket 6, the cantilever hook can be inserted into the fixing hole. Once the cantilever hook is inserted into the fixing hole, a wall of the fixing hole can confine the cantilever hook and prevent it from easily slipping out. In this way, the first fastening section 42 and the second fastening section 62 can be stably connected to each other; that is, the heat dissipation base 4 and the bracket 6 can be fixed together, effectively preventing the heat dissipation base 4 from detaching from or falling off the bracket 6, and improving the stability of the entire hair removal device.

[0193] As in Fig. 16, Fig. 17 and Fig. As shown in Figure 19, the holder 6 secures the second translucent body 7. The second translucent body 7 can be square or rectangular and is embedded in the window 61. The second translucent body 7 is arranged on a side of the filter facing away from the light source 2. The second translucent body 7 has a light-incidence surface 71 facing the light source 2 and a light-emitting surface 72 facing away from the light source 2. In some embodiments, the second translucent body 7 can be a crystal. Alternatively, the second translucent body 7 can be a diamond. In the present embodiments, the second translucent body 7, which is the crystal, can be taken as an example.

[0194] During operation of the hair removal device, the light source 2 emits light, which is reflected by the reflector 1. The light then passes through the filter and is reflected again to reach the crystal. The light enters the crystal through the light-incidence surface 71. The light can be reflected by the crystal itself and exits the crystal through the light-emission surface 72. The light emitted from the light-emission surface 72 can illuminate an area of ​​skin where the hair to be removed is located, thus removing it.

[0195] In some embodiments, the number of TEC cooling plates can be two or three. For example, two TEC cooling plates can be arranged, spaced apart from each other. One of the two TEC cooling plates is fixed to the heat dissipation base 4, and the other of the two TEC cooling plates is arranged on the bracket 6. The bracket 6 defines a mounting opening that communicates with the window 61. When the second translucent body 7 is embedded in the window 61, the TEC cooling plate is embedded in the mounting opening and abuts the second translucent body 7. The TEC cooling plate cools the second translucent body 7 so that the heat from the second translucent body 7 can be dissipated quickly.The temperature of the second translucent body 7 can be effectively reduced, optimally preventing heating of the light-emitting surface 72, so that the hair removal device can safely come into contact with the skin area where the hairs to be removed are located, and the user can use the hair removal device more comfortably.

[0196] In some embodiments, for example, three TEC cooling plates can be arranged. One of the three TEC cooling plates is fixed to the heat dissipation base 4, and the other two TEC cooling plates are embedded in the holder. The other two TEC cooling plates are each arranged on two sides of the second translucent body 7. The two sides can be a top and a bottom of the second translucent body 7, facing in the direction in which the light exits the second translucent body 7, or a left side and a right side of the second translucent body 7.The two TEC cooling plates, which are arranged on both sides of the second translucent body 7, improve the efficiency of the cooling of the second translucent body 7, so that the heat of the second translucent body 7 can be dissipated quickly, thereby achieving the cooling effect and improving the heat dissipation efficiency of the hair removal device.

[0197] As in Fig. As shown in Figure 20, in some embodiments the structures and relative positions of the light source 2, the reflector 1, and the second translucent body 7 can satisfy the following conditions. The uniformity of the light-emitting surface 72 can be greater than or equal to 90%, or light spots on the light-emitting surface 72 can occupy at least 95% of the area of ​​the light-emitting surface 72. If the uniformity of the light-emitting surface 72 is greater than or equal to 90%, the hair removal effect of the hair removal device can be improved, allowing the hair on the skin to be removed evenly. Similarly, the hair on the skin can be removed evenly, and the utilization of the light can be improved, if the light spots on the light-emitting surface 72 occupy at least 95% of the area of ​​the light-emitting surface 72.

[0198] If the light-emitting surface 72 of the hair removal device emits light less uniformly, or if the light spots occupy a relatively small area of ​​the light-emitting surface 72, the hair removal device may need to irradiate a position several times during use to remove the hair evenly; otherwise, the hair may not be removed evenly, and the skin may not look satisfactory. With the structures and relative positions of the light source 2, the reflector 1, and the second translucent body 7 in the present embodiment, the uniformity of the light-emitting surface 72 is greater than or equal to 90%, or the light spots occupy at least 95% of the area of ​​the light-emitting surface 72. In this way, the hair removal device does not need to irradiate a position several times.If the quality of the light source 2 and the power of the hair removal device are configured correctly and the user's health is ensured, the hair removal device can irradiate one position once to efficiently and evenly remove the hair in that position.

[0199] In some embodiments, a center point of the reflector 1, a center point of the light source 2, and a center point of the second translucent body 7 can lie on a straight line. By adjusting the distance between the centers on this straight line, the uniformity of the light-emitting surface 72 can be greater than or equal to 90%, or the light spots can occupy at least 95% of the area of ​​the light-emitting surface 72. In some embodiments, the structures of the reflector 1, the light source 2, and the second translucent body 7 can be adapted so that the hair removal device fulfills the aforementioned features.

[0200] In some embodiments, the center of the light source 2 is located between a focal point of the reflector 1 (shown as 1a in the drawing) and an underside of the reflector 1. The light-incident surface 71 of the second translucent body 7 is located between the light-emitting surface 72 and the focal point of the reflector 1. Furthermore, the light reflected by the reflector 1 can be focused to a position between the light-emitting surface 72 of the second translucent body 7 and the focal point of the reflector 1. By configuring the positions of the light source 2, the reflector 1, and the second translucent body 7, the uniformity of the light-emitting surface 72 can be greater than or equal to 90%, or light spots on the light-emitting surface 72 can occupy at least 95% of the area of ​​the light-emitting surface 72.In this way, the light emitted by the light source 2 can be completely reflected by the reflector 1 to reach the second translucent body 7, thereby improving the uniformity with which the second translucent body 7 emits the light.

[0201] As in Fig. As shown in Figure 19, the reflector 1 has a first reflective area 11 and a second reflective area 12. The first reflective area 11 is a curved area forming the base of the reflector 1, and the second reflective area 12 consists of two flat areas extending outwards from two ends of the curved area. The flat areas may be tangential to the curved area. In some embodiments, the light source 2 may be a strip lamp. The strip lamp emits light, and the curved area of ​​the reflector 1 can reflect the light to the second translucent body 7. Furthermore, the flat areas of the reflector 1 can also reflect light to the second translucent body 7.The light can be sufficiently reflected through the curved area and the flat areas, thus improving the light emission rate and the utilization of the light.

[0202] When the hair removal device is in operation, the light source 2 emits light, whereby the first reflective area 11 and the second reflective areas 12 of the reflector 1 can reflect the light completely onto the second translucent body 7. The light enters the second translucent body 7 from the incident surface and then exits the second translucent body 7 via the emitting surface 72, such that the uniformity of the emitting surface 72 can be greater than or equal to 90%, or light spots on the emitting surface 72 can cover at least 95% of the area of ​​the emitting surface 72. In this way, the uniformity with which the hair removal device emits light can be improved, and the hair removal effect of the device can be enhanced.

[0203] In some embodiments, the angle between the flat area and a reference line can be between 5 and 20 degrees. The reference line can be a line between the center of the light source 2 and the center of the second translucent body 7. For example, the angle between the flat area and the reference line can be 5 degrees, 8 degrees, or 15 degrees. By configuring the angle between the flat area and the reference line, the light can be completely reflected onto the second translucent body 7. This reduces light waste and lowers operating costs. It also improves the uniformity with which the second translucent body 7 emits light.

[0204] For example, the focal point can be located closer in the area mentioned above. If the conditions regarding light uniformity and light utilization are met, the second translucent body 3 can be located closer to the light source 2, allowing the hair removal device to have a more compact structure and saving material in its manufacture.

[0205] As in Fig. 16, Fig. 17 and Fig. As shown in Figure 19, the hair removal device can further comprise a side reflection element 13 arranged at each of the two ends of the reflector 1 along a longitudinal direction of the reflector 1. The side reflection element 13 can reflect light emitted from the two ends of the reflector 1 onto the light-emitting side of the reflector 1. The side reflection element 13 completely reflects the light emitted by the light source 2 to improve the light utilization rate and enable efficient hair removal by the hair removal device. In addition, the light source 2 can be easily assembled by means of the side reflection element 13, which improves assembly efficiency.

[0206] In some embodiments, the side reflection element 13 and the reflector 1 can be formed as a single-piece structure. This reduces the manufacturing difficulty of the side reflection element 13 and the reflector 1. When the side reflection element 13 and the reflector 1 form a single-piece structure, the structure can be stable and rigid, the stability of the connection between the side reflection element 13 and the reflector 1 can be improved, and the service life of the reflector 1 can be increased.

[0207] In some embodiments, the light source 2 can be a strip-shaped lamp. Each of the two side-reflecting elements 13, arranged on each side of the reflector 1, defines a through-hole 131, and the two side-reflecting elements 13 at the two ends can define two through-holes 131. The two ends of the lamp each pass through the two through-holes 131. A fixing element 8 is connected to each end of the lamp to movably fix the light source 2 to the reflector 1. The fixing element 8 can, for example, be a soft silicone cover. Alternatively, the fixing element 8 can be a rubber cover. The fixing element 8 can be cylindrical. The fixing element 8 can define a mounting slot 81. Each end of the lamp is embedded in the mounting slot 81.The fixing element 8 defines a fixing hole 82 along an axis of the fixing element 8. The fixing hole 82 is connected to the mounting slot 81. A mounting post 21 is arranged at each of the two ends of the lamp, extending from the lamp. The mounting post 21 can extend through the fixing hole 82. The fixing element 8 can be arranged on an outer surface of the reflector 1.

[0208] In some embodiments, a support block 43 is arranged at each of the two ends of the heat dissipation base 4, and the support block 43 and the heat dissipation base 4 can be formed as a single-piece structure. The support block 43 defines a notch. Each of the two ends of the light source 2 and a corresponding fixing element 8 can be received in the notch. When the heat dissipation base 4 and the support block 43 are attached, the support block 43 and the mounting block 43 can fix the fixing element 8, thus securing the lamp to the reflector 1. The fixing element 8 itself can be elastic. While the support block 43 and the mounting block 43 fix the fixing element 8, the shape of the fixing element 8 can change accordingly when it is compressed to conform to the shape of the notch.Furthermore, the pressure exerted on the lamp can be optimally reduced, thereby minimizing damage to the lamp.

[0209] The present disclosure provides a hair removal device with improved heat dissipation. The light source 2 is arranged within the reflector 1 and configured to emit light. The reflector 1 reflects the light, enabling the hair removal device to emit light to remove hair from the skin. The first translucent body 3 and the reflector 1 together form a cavity to house the light source 2, which is suspended within this cavity. Two sides of the heat dissipation base 4 can each be thermally coupled to the reflector 1 and the cooling element 5, respectively, allowing heat to be rapidly dissipated from the cavity. Specifically, the heat in the cavity can be transferred to the heat dissipation base 4 and the cooling element 5. In this way, the cavity can be cooled, and the heat dissipation effect of the hair removal device is improved.Furthermore, the heat from light source 2 can be dissipated evenly, which extends the lifespan of light source 2. In addition, the improved heat dissipation allows the user to operate the hair removal device comfortably.

[0210] As in Fig. 26 and Fig. As shown in Figure 27, in a further embodiment an elastic sealing ring 16 is arranged between the second translucent body 7 and the first translucent body 3. The elastic sealing ring 16 can be annular. The second translucent body 7 and the first translucent body 3 can be sealed by the elastic sealing ring 16. In this way, no condensation can form between the first translucent body 3 and the second translucent body 7. No dirt can penetrate the connection between the first translucent body 3 and the second translucent body 7. The elastic sealing ring 16 can preferably be annular.

[0211] If the hair removal device falls to the ground, the second translucent body 7 can, of course, collide hard with the ground. An impact from a conventional second translucent body 7 can be transmitted to the first translucent body 3, causing the first translucent body 3, the reflector 1, and the light source 2 to vibrate and potentially be damaged. In the hair removal device of the present embodiment, the impact force can be eliminated by the elastic sealing ring 16 when the second translucent body 7 impacts the ground.Due to the elasticity of the elastic sealing ring 16, it can deform elastically under external forces, thereby reducing or eliminating the impact between the second translucent body 7 and the first translucent body 3 and reducing the likelihood of damage to the first translucent body 3, the reflector 1, and the light source 2 from the impact force. This improves the collision protection performance of the hair removal device.

[0212] As in the Fig. As shown in Figures 28 to 30, the elastic sealing ring 16 has an inner ring 161 that transmits light. After being filtered through the first transparent body 3, the light can be guided through the inner ring 161 to the second transparent body 7 and further illuminate the user's skin.

[0213] In the present embodiment, the first translucent body 3 and the second translucent body 7 can be fixed directly to the holder 6. The first translucent body 3 and the second translucent body 7 cannot move relative to the holder 6. Therefore, during use of the hair removal device, it is prevented that the second light transmission body 7 moves backward relative to the holder 6 due to a human bone or a sharp object striking it. This prevents the first light transmission body 3 or the hair removal assembly 100 from being irreparably deformed by compression. The elastic sealing ring 16 can be irreparably deformed by repeated compression. In this way, the light-guiding effect of the hair removal device is not impaired, and a waste of light energy is avoided.

[0214] The elastic sealing ring 16 further defines a mounting groove 162, which communicates with an opening in the inner ring 161. The mounting groove 162 is defined on a side of the elastic sealing ring 16 facing away from the hair removal device 100. The inner ring 161 extends from a bottom wall of the mounting groove 162 to the first translucent body 3. The second translucent body 7 is partially received in the mounting groove 162 to improve the sealing effect between the second translucent body 7 and the elastic sealing ring 16 and to fix the elastic sealing ring 16 to the second translucent body 7, thus creating a secure connection between the elastic sealing ring 16 and the second translucent body 7.

[0215] In some embodiments, the elastic sealing ring 16 can have an outer ring 163 and a projection 164 located on one side of the outer ring 163. The projection 164 can abut the first translucent body 3. One side of the outer ring 163 facing away from the projection 164 defines the mounting groove 162. The inner ring 161 extends from the bottom wall of the mounting groove 162 to the projection 164. The outer ring 163 and the projection 164 can each have a fully closed loop structure. Light within the inner ring 161 can only be emitted outwards from the second translucent body 7.

[0216] In some embodiments, the cross-section of the projection 164 can be a transversely oriented triangle. The contact area between the projection 164 and the first translucent body 3 can be smaller than the contact area between the projection 164 and the outer ring 163. Therefore, when the elastic sealing ring 16 is in place, the end of the projection 164 furthest from the outer ring 163 can be partially corrugated after compression. Since the elastic sealing ring 16 is elastic, a corrugated portion of the elastic sealing ring 16 can bear firmly against the first translucent body 3. That is, if the distance between the first translucent body 3 and the second translucent body 7 changes slightly, the elastic sealing ring 16 can be adjusted by adjusting the corrugated portion to accommodate the change in distance.In this way, a tight fit or even an interference fit can be maintained at all times between the elastic sealing ring 16 and the first translucent body 3, as well as between the elastic sealing ring 16 and the second translucent body 7, thereby achieving a better sealing effect. In other embodiments, the cross-section of the projection 164 can be trapezoidal.

[0217] In the present embodiment, the elastic sealing ring 16 can be a ring made of a laser-resistant, high-temperature-resistant and low-temperature-resistant material, so that when using the elastic sealing ring 16, it can be prevented that the elastic sealing ring 16 deforms due to high or low temperatures or laser irradiation, thereby increasing the service life of the elastic sealing ring 16.

[0218] As in Fig. 21 shown, is Fig. Figure 21 shows a schematic structural view of the hair removal device according to a further embodiment of the present disclosure. The hair removal device can have a head section 111 and a hand section 112 connected to the head section 111. The head section 111 is provided with a cold-compression section 1111, which is configured to be attached to the skin. The cold-compression section 1111 can emit light to irradiate the hair follicles of the skin. The light can penetrate the skin to irradiate the hair follicles and remove the hair. In addition, the cold-compression section 1111 can rapidly cool the skin to reduce skin burns caused by the light. In this way, the user can use the hair removal device comfortably.In some embodiments, the cold compression section 1111 can emit light for skin care, so that the hair removal device can remove hair and perform skin care simultaneously.

[0219] In some embodiments, the hand section 112 may have a housing that defines a space in the center (not marked in the drawings). A surface of the housing may define a vent opening 1211. The vent opening 1211 may be connected to an interior and an exterior of the housing, allowing the hair removal device to exchange air with the outside environment via the vent opening 1211 and thus lowering the temperature inside the device. The housing may further include an interface 1212 configured for connection to an external power supply for charging the hair removal device. The present disclosure does not limit the position of the interface 1212 on the housing.

[0220] As in Fig. 21 and Fig. 22 shown, is Fig. 22 An exploded view of the device according to a further embodiment of the present disclosure. An arrow in Fig. Figure 22 shows the direction of the airflow within the hair removal device, driven by the cold drive assembly. A straight line represents the direction in which cold air flows, and a wavy line represents the direction in which hot air flows. Specifically, the hair removal device may comprise the housing, a light cover 113 arranged over an opening in the housing, a hair removal mechanism 14 contained within the housing, and a bottom cover 15.

[0221] In the present embodiment, the housing can comprise a first housing 121 and a second housing 122. The first housing 121 and the second housing 122 can be interlocked to define a cavity and two openings at two ends of the housing. The hair removal mechanism 14 is accommodated in the cavity, and the light cover 113 and the bottom cover 15 are arranged to cover the two openings, respectively, to close the openings defined by the first housing 121 and the second housing 122 after the first housing 121 and the second housing 122 have been interlocked to define the cavity.

[0222] In some embodiments, the first housing 121, the second housing 122, the light cover 113 and the bottom cover 15 can be connected by snap fasteners, screws, adhesives, etc.

[0223] The hair removal mechanism 14 can include the hair removal assembly 100, the cold compression assembly 200, the heat dissipation base 300 and the cold drive assembly 400.

[0224] The cold compression assembly 200 is located near the light cover 113. The light cover 113 may have a through-hole (not marked in the drawings). A portion of the cold compression assembly 200 is exposed through the through-hole in the light cover 113 to make direct contact with the skin. It is understood that this portion of the cold compression assembly 200 and the light cover 113 together form the head section 111 of the hair removal device.

[0225] The hair removal device 100 is located on one side of the cold compression assembly 200, facing away from the light cover 113, and is configured to emit light towards the cold compression assembly 200. The light can be visible light, such as red, green, or yellow light. Once the light enters the cold compression assembly 200, it can pass through it to penetrate further into the skin and reach the hair follicle beneath the skin to remove hair.

[0226] The heat dissipation base 300 is arranged on one side of the cold compression assembly 200 and connected to it. When applied to the skin, the cold compression assembly 200 can absorb heat from the skin to lower its temperature and reduce the risk of burns. However, the temperature of the cold compression assembly 200 can rise with prolonged use, potentially reducing its cooling effect. The heat dissipation base 300 absorbs this heat, allowing the cold compression assembly 200 to continue operating at a lower temperature, thus ensuring that the cold compression assembly 200 continues to cool the skin. Therefore, in this embodiment, the hair removal device can operate at a constant low temperature during continuous use, preventing injury to the user.

[0227] The cooling drive assembly 400 is arranged on one side of at least one part of the heat dissipation base 300 facing away from the hair removal device 100 and is configured to dissipate heat from the hair removal device 100 and the heat dissipation base 300.

[0228] In the present embodiment, the cooling drive assembly 400 can accommodate an external cooling medium that passes through the vent opening 1211 and enters the interior of the hair removal device. The cooling medium can flow along the hair removal device 100 and the heat dissipation base 300 to dissipate heat and then exit the device through the vent opening 1211.

[0229] In some embodiments, the external cooling medium can be air. The cooling drive assembly 400 can draw in the air and blow it towards the hair removal assembly 100 and the heat dissipation base 300. The heat from the hair removal assembly 100 and the heat dissipation base 300 can be dissipated by the airflow.

[0230] In the present embodiment, the vent opening 1211 can be defined in the first housing 121, and at least a part of the refrigeration drive assembly 400 faces the vent opening 1211, so that the refrigeration unit assembly 400 can better absorb the external cooling medium entering the housing through the vent opening 1211, thus improving heat dissipation efficiency. In other embodiments, the vent opening 1211 can be defined in the second housing 122.

[0231] As in Fig. 22 and Fig. 23 shown, is Fig. 23 an exploded view of the in Fig. Structure shown in 22, where the arrows are in Fig. 23 can indicate the direction in which air is blown out of a fan.

[0232] In the present embodiment, the hair removal device can further comprise a holder 500, a circuit board 600, a processor 700, and a capacitor 800. The hair removal assembly 100 and the cold compression assembly 200 can be arranged within the holder 500, and the cold drive assembly 400 can be arranged adjacent to the holder 500. The hair removal assembly 100, the cold compression assembly 200, and the cold drive assembly 400 can be mounted on the circuit board 600 and electrically connected to it.

[0233] The processor 700 and the capacitor 800 can be electrically connected to and mounted on the circuit board 600. When an external power supply is connected, it can charge the capacitor 800, which can then power the hair removal device. Furthermore, the capacitor 800 can store energy when connected to the external power supply, allowing the hair removal device to be used even without the external power supply. The processor 700 can send control commands to the hair removal assembly 100, the cold compression assembly 200, and the cold drive assembly 400 to control the operation of the hair removal device.For example, the hair removal device can be controlled to turn on and off, heat protection of the hair removal device can be controlled, power of the hair removal device can be adjusted, and so on.

[0234] In the present embodiment, the printed circuit board 600 can be fixed in the second housing 122, and the printed circuit board 600 can be a PCBA printed circuit board.

[0235] In the prior art, the heat inside the hair removal device can continuously increase during use. Circuits and components inside the hair removal device can explode, burn out, short-circuit, etc., when operating at high temperatures. In the present embodiment, the cooling drive assembly 400 can dissipate heat from the hair removal assembly 100 and the heat dissipation base 300, and the heat dissipation base 300 can dissipate heat from the cold compression assembly 200, so that the cold compression assembly 200 can compress the skin to cool it, making the skin feel comfortable and preventing the components from exploding, burning out, short-circuiting, etc.

[0236] Specifically, the hair removal device 100 can comprise a light source 101, a reflector 102, a filter 103 and two electrodes 104.

[0237] The light source 101, the reflector 102, and the filter 103 are arranged within the holder 500; that is, the holder 500 is configured with mounting positions for the light source 101, the reflector 102, and the filter 103. The light source 101, the reflector 102, and the filter 103 can be snapped into the mounting positions in the holder 500 accordingly.

[0238] The light source 101 can be positioned opposite the cold compression assembly 200. The light emitted by the light source 101 can be directed straight into the cold compression assembly 200. The reflector 102 can be positioned on the side of the light source 101 facing away from the cold compression assembly 200 and can reflect the light from the light source 101 into the cold compression assembly 200 to prevent loss of light energy. The filter 103 is positioned between the light source 101 and the cold compression assembly 200. That is, the light source 101, the filter 103, and the cold compression assembly 200 can be arranged sequentially in the direction of light propagation. The filter 103 is configured to filter out a portion of the harmful light emitted by the light source 101, thus reducing light-induced skin damage and increasing the safety of hair removal.The two electrodes 104 can be connected to two sides of the light source 101 and electrically connected to the circuit board 600 to transmit electrical signals.

[0239] In some embodiments, the light source 101 can be a lamp, and the color of the light emitted by the lamp is not limited. The lamp can emit colored light, composite light, etc. The wavelength and frequency of the light can be set as required. The type of lamp is not limited. The lamp can be a xenon semiconductor lamp, a quartz lamp, a laser lamp, etc. The type of light can be intense pulsed light (IPL), deep pulsed light (DPL), optimal pulse technology (OPT), advanced optimal pulse technology (AOPT), broadband light (BBL), etc. The type of light can be determined based on the desired effects.

[0240] In some embodiments, the reflector 102 can be a U-shaped reflector surrounding the light source 101. Furthermore, an opening of the U-shaped reflector can face the cold compression assembly 200 and reflect light that does not enter the cold compression assembly 200 back to it. In addition, the reflector 102 can prevent the heat generated by the light source 101 from being transferred to other components of the hair removal device. In the present embodiment, the holder 500 can have a fixing frame 550 and a tube 560. The fixing frame 550 can define a first receiving space 510 and a second receiving space 520. The first receiving space 510 is configured to receive the hair removal assembly 100. The second receiving space 520 is configured to receive the cold compression assembly 200.The first recording chamber 510 can be adjacent to the second recording chamber 520 to reduce the distance between the hair removal device 100 and the cold compression assembly 200, thereby reducing the loss of light emitted by the hair removal device 100. The second recording chamber 520 can be located closer to the head section 111 of the [unit / device]. Fig. The hair removal device shown in 21 is located in the first recording room 510.

[0241] When the hair removal device is in operation, the light source 101 can generate a large amount of heat, which can irradiate the reflector 102 and the filter 103, thus increasing their temperature. Therefore, the heat from the light source 101, the reflector 102, and the filter 103 must be dissipated.

[0242] In the present embodiment, the bracket 500 can comprise the fixing frame 550 and the tube 560. One end of the tube 560 can be connected to one side of the fixing frame 550, and the other end of the tube 560 can extend to the refrigeration drive assembly 400. The fixing frame 550 defines an air outlet 540 that communicates with the first receiving chamber 510, and the tube 560 defines an air inlet 530 that communicates with the first receiving chamber 510. The air inlet 530, the first receiving chamber 510, and the air outlet 540 can be sequentially connected to one another.

[0243] The air inlet 530 can be connected to the refrigeration drive assembly 400. The air outlet 540 can be connected to the vent 1211. The refrigeration drive assembly 400 can draw in outside air from the vent 1211 and blow the air towards the air outlet 540. The air enters the first receiving chamber 510 through the air outlet 540 and conducts heat away from the light source 101, the reflector 102, and the filter 103 in the first receiving chamber 510. Furthermore, the air can flow out of the device through the air outlet 540 and the vent 1211 to dissipate the heat.

[0244] In some embodiments, part of the fixing frame 550 and part of the tube 560 form a first support 501, and the remaining part of the fixing frame 550 and the remaining part of the tube 560 form a second support 502. In other embodiments, the fixing support 550 can be configured as a one-piece structure.

[0245] The first bracket 501 and the second bracket 502 can be connected to each other via a snap-fit ​​connection. The first bracket 501 can be located near the first housing 121, and the second bracket 502 can be located near the second housing 122. The air outlet 540 can be defined in the first bracket 501 and can be located opposite the vent 1211 in the first housing 1211 to increase the heat dissipation efficiency at the air outlet 540. The first receiving chamber 510 can be defined in a portion of the first bracket 501 and a portion of the second bracket 502. This portion of the first bracket 501 and the portion of the second bracket 502 can correspond to the fixing frame 550 and snap together. The air inlet 530 can be defined in another portion of the first bracket 501 and another portion of the second bracket 502.The other part of the first bracket 501 and the other part of the second bracket 502 can correspond to the tube 550 and be interlocked together. The air inlet 530 can be connected to the first receiving chamber 510 and to the refrigeration drive assembly 400. An interior of the bracket 6 can define a channel for directing an airflow, thereby directing the airflow from the refrigeration drive assembly 400 into the first receiving chamber 510.

[0246] Therefore, in the present embodiment, the hair removal assembly 100 can dissipate heat via the cooling drive assembly 400, thus ensuring that the hair removal device can be used safely.

[0247] Furthermore, in the present embodiment, the cold compression assembly 200 can have a second translucent body 201 and a cooling element 202.

[0248] The second translucent body 201 can be configured to be attached to the skin. The second translucent body 201 can face the light source 101. The second translucent body 201 can be a light-transmitting element. The light emitted by the light source 101 enters the second translucent body 201 and passes through it to reach the skin.

[0249] In some embodiments, the second transparent body 201 can be a light-conducting crystal, such as sapphire, K9 glass, or crystal glass. If the second transparent body 201 is made of sapphire, it can exhibit excellent thermal conductivity.

[0250] In some embodiments, the second translucent body 201 can be cylindrical or cuboid. A surface of the second translucent body 201 facing away from the light source 101 can be configured so that it can be attached to the skin.

[0251] The cooling element 202 can be connected to the second translucent body 201 to absorb heat from it. Since the temperature of the second translucent body 201 increases when it comes into contact with the skin, the cooling element 202 can absorb this heat, keeping the second translucent body 201 cool. Furthermore, if the second translucent body 201 remains in contact with the skin for an extended period, it can continue to cool the skin, thereby reducing any burning sensation.

[0252] Furthermore, the cooling element 202 can be a semiconductor cooling element. One end of the cooling element 202, which absorbs heat, can be connected to the second translucent body 201, and the other end of the cooling element 202 can dissipate the heat.

[0253] In order to dissipate heat from the heat dissipation end of the cooling element 202, in the present embodiment the heat dissipation base 300 is connected to the heat absorption end of the cooling element 202 and absorbs the heat from the cooling element 202.

[0254] Specifically, the heat dissipation base 300 can comprise a heat dissipation plate 301 and a heat dissipation wing 302. One surface of the heat dissipation plate 301 has a first region 310 and a second region 311, which are arranged side by side. The hair removal device 100 is arranged in the first region 310, and the heat dissipation wing 302 is arranged in the second region 311. The second region 311 is arranged on one side of the fixing frame 550, which is connected to the tube 560. The heat dissipation wing 302 and the tube 560 are arranged side by side on one side of the fixing frame. The fixing frame 550 is arranged in the first region 310. The heat dissipation plate 301 is arranged on the circuit board 600 and connected to the cold compression assembly 200. Specifically, the cooling element 5 can be connected to the heat dissipation plate 301 by means of a thermally conductive silicone grease.The cold compression assembly 200 can quickly transfer heat to the heat dissipation plate 301 via the thermally conductive silicone grease. The heat dissipation vane 302 can dissipate heat from the heat dissipation plate 301 and assist the heat dissipation plate 301 in this process, enabling the heat dissipation plate 301 to continuously absorb heat from the cooling element 202.

[0255] In some embodiments, the number of heat dissipation wings 302 can be more than one. The additional heat dissipation wings 302 can be parallel to each other and attached to the heat dissipation plate 301 by welding.

[0256] In some embodiments, a surface of the heat dissipation wing 302 can be sprayed with a thermally conductive coating. The thermally conductive coating can radiate heat away from the heat dissipation wing 302 and prevent the heat dissipation wing 302 from being affected by water, corroding, and wearing down.

[0257] In the present embodiment, the heat dissipation plate 301 can be a temperature-homogeneous plate. When a liquid within the temperature-homogeneous plate comes into contact with a high-temperature environment, the liquid can absorb heat and evaporate into a gas. When the gas comes into contact with a low-temperature environment, the gas can release heat and condense back into a liquid. Therefore, the temperature of a surface of the temperature-homogeneous plate can be kept homogeneous due to periodic evaporation and condensation. Thus, part of the surface of the heat dissipation plate 301 is connected to the cooling element 5, and the other part is connected to the heat dissipation vane 302 such that the heat generated by the cooling element 202 can be dissipated via the heat dissipation plate 301 and the heat dissipation vane 302.

[0258] In some embodiments, such as in Fig. As shown in Figure 24, the carbon-containing layer 92 can be arranged between the second transparent body 201 and the heat dissipation base 300, for example on a surface of the heat dissipation plate 301 that is thermally coupled to the second transparent body 201. The carbon-containing layer 92 has excellent thermal conductivity and can accelerate the heat conduction rate of the heat dissipation plate 301 and improve the heat dissipation performance of the heat dissipation base 300.

[0259] In some embodiments, the carbon-containing layer can be a graphene material, graphite powder, a graphite foil, or a graphite film.

[0260] In some embodiments, the carbon-containing layer can be arranged by plating, spraying, or bonding.

[0261] To improve the heat dissipation performance of the heat dissipation base 300, the heat dissipation base 300 can also be connected to the refrigeration drive assembly 400 in the present embodiment.

[0262] Specifically, the heat dissipation vane 302 of the heat dissipation base 300 can be connected to the cooling drive assembly 400. The cooling drive assembly 400 can draw in outside air through the vent opening 1211 and force the air to flow towards the heat dissipation vane 302. The air can then flow along the heat dissipation vane 302 to dissipate heat from it.

[0263] In one example, the heat dissipation vane 302 can be arranged parallel to an airflow direction driven by the refrigeration drive assembly 400 in order to increase a contact area between the heat dissipation vane 302 and the airflow, thereby increasing the efficiency of heat dissipation from the heat dissipation vane 302.

[0264] The heat dissipation vane 302 can face the vent opening 1211 in the first housing 121. After flowing along the heat dissipation vane 302, the airflow can quickly exit the device through the vent opening 1211.

[0265] Therefore, the cooling drive assembly 400 of the present embodiment can drive the cooling medium to dissipate heat from the hair removal assembly 100 and can further dissipate heat from the heat dissipation base 300. With improved safety, the irradiated skin can be compressed for cooling, and the risk of skin burns can be reduced. Furthermore, the cooling compression assembly 200 can be controlled by the heat dissipation base 300 and the cooling drive assembly 400 to reach a low temperature of approximately zero degrees. In this way, the skin near a light exit aperture can approach the freezing point extremely closely, the burning sensation on the skin can be reduced, and brief contact between the skin and the device cannot cause skin damage.

[0266] As in Fig. 22, Fig. 23 and Fig. 25 shown, is Fig. 25 a structural schematic view of an air outlet of a fan housing of the in Fig. 23. In the present embodiment, the refrigeration drive assembly 400 can comprise a fan housing 401 and a fan 402. The fan housing 401 is arranged on one side of the heat dissipation base 300 that is away from the refrigeration compression assembly 200, and the fan 402 is housed inside the fan housing 401.

[0267] An air inlet end of the fan 402 faces the vent opening 1211 in the first housing 121. The fan 402 drives the outside air to flow through the vent opening 1211 into the fan 402. The fan housing 401 defines an air outlet 410 for discharging air. An air outlet end of the fan 402 is connected to the air outlet 410. The fan 402 drives the outside air to flow through the vent opening 1211 into the fan 402 and further drives the air to flow out through the air outlet 410.

[0268] In some embodiments, the fan 402 can be a radial fan, an axial fan, a mixed-flow fan or a cross-flow fan.

[0269] Furthermore, the air outlet 410 can have a first air outlet 411 and a second air outlet 412. The air at the air outlet 410 of the fan 402 can be divided into two parts. One part of the air flows out of the device through the first air outlet 411, and the other part of the air flows out of the device through the second air outlet 412.

[0270] In some embodiments, the air outlet 410 may further comprise a third air outlet or multiple air outlets. The present disclosure does not limit the number of air outlets.

[0271] In the present embodiment, the first air outlet 411 is connected to the air inlet 530 of the bracket 500. The fan 402 drives the outside air to flow into the fan 402 through the vent 1211. The fan 402 drives the air to flow from the first air outlet 411 and the air inlet 530 into the first receiving chamber 510. The air in the first receiving chamber 510 can dissipate heat from the light source 101, the reflector 102, and the filter 103. Finally, the air flows out of the device through the air outlet 540 and the vent 1211. In this way, the heat is released to the outside of the device, thus dissipating the heat from the hair removal device 100.

[0272] In the present embodiment, the second air outlet 412 is connected to the heat dissipation vane 302 of the heat dissipation base 300. The fan 402 drives the outside air so that it enters the fan 402 from the vent opening 1211. The fan 402 drives the air to flow through the second air outlet 412 between each pair of the multiple heat dissipation vanes 302 of the heat dissipation base 300. The air flows along the heat dissipation vanes 302, conducts the heat away from the heat dissipation vanes 302, and then flows out of the device through the air outlet 1211. Once the temperatures of the heat dissipation vanes 302 have decreased, the heat from the heat dissipation plate 301 can be reduced accordingly. In this way, the heat dissipation plate 301 can absorb the heat from the cold compression assembly 200, thereby dissipating the heat from the cold compression assembly 200.

[0273] In some embodiments, the amount of air flowing into the first air outlet 411 and the second air outlet 412 is not limited and can be determined based on demand. The amount of air flowing into the first air outlet 411 and the second air outlet 412 can be controlled by configuring the size of the first air outlet 411 and the size of the second air outlet 412. For example, in the present embodiment, the air outlet area of ​​the second air outlet 412 is larger than the air outlet area of ​​the first air outlet 411, so that a greater volume of air flows through the second air outlet 412 to improve the efficiency of heat dissipation from the heat dissipation plate 301.

[0274] According to the embodiments described above, in the hair removal device of the present embodiment, the heat from the hair removal assembly 100, the cold compression assembly 200, and the heat dissipation base 300 can be dissipated by the cold drive assembly 400, so that the heat from the hair removal assembly 100 and the cold compression assembly 200 can be dissipated simultaneously. The heat dissipation performance of the hair removal device can be improved, and the safety of the hair removal device can be enhanced. Additionally, the skin can be compressed for continuous cooling, and the skin temperature can be allowed to approach freezing point indefinitely, thus reducing the burning sensation and protecting the skin from damage during hair removal.

[0275] As in Fig. As shown in Figure 31, the hair removal device comprises reflector 1 and light source 2. Reflector 1 can be a conductor. When the device is energized, a strong electric field can be generated. Light source 2 is located inside and opposite reflector 1. Light source 2 can be a strip gas excitation light source and can be excited by reflector 1 to emit light after the reflector 1 has been conducted. Reflector 1 has a light-emitting face. Light can be reflected, and light can be emitted from the light-emitting face of reflector 1. The distance between the body of light source 2 and reflector 1 is greater than zero and less than or equal to 0.3 mm.In one embodiment of an arrangement of the light source 2, for example, the distance between the body of the light source 2 and the reflector 1 can be 0.3 mm; or the distance between the body of the light source 2 and the reflector 1 can be 0.15 mm. Similarly, the distance between the light source 2 and the reflector 1 can be determined based on the structure of the reflector 1 and the structure of the light source 2, whereby the distance between the body of the light source 2 and the reflector 1 can be less than 0.3 mm.

[0276] When the hair removal device is in operation and the reflector 1 is guided, a strong electric field can be generated in the reflector 1. A high voltage generated by the reflector 1 can ionize the gas in the light source 2, creating an arc for discharge. This means that the light source 2 can emit light. By defining the distance between the light source 2 and the reflector 1, the voltage in the reflector 1 can excite the light source 2 to emit light. In contrast to using a trigger wire to excite the lamp, in the present embodiment the reflector 1 excites the lamp to emit light without a trigger wire. In this way, the way the lamp is excited to emit light can be improved, the material required for manufacture can be reduced, and manufacturing costs can be lowered.

[0277] In some embodiments, the reflector 1 is a semi-arc reflector 1. The light source 2 can be a strip lamp. The lamp is suspended inside the reflector 1. In this way, the body of the lamp and an inner wall of the reflector 1 together form an excitation chamber. The voltage in the reflector 1 can excite the lamp without a trigger wire. The gas inside the lamp can be ionized, allowing the lamp to emit light. The reflector 1 can excite the lamp to light by means of the high voltage, and additionally, the reflector 1 can serve as a mounting platform for the light source 2. In this way, the trigger wire or other components for exciting the lamp to light can be omitted, saving manufacturing material and reducing manufacturing costs.Furthermore, the number of components arranged in reflector 1 can be reduced and space saved, so that reflector 1 can reflect the light emitted by light source 2 outwards, thereby improving the light emission rate.

[0278] In some embodiments, the reflector 1 can be strip-shaped.

[0279] As in Fig. 31 and Fig. As shown in Figure 32, in some embodiments the hair removal device comprises the heat sink 3, an elastic element 4, and the bracket 5. The heat dissipation base 3 can be strip-shaped. The reflector 1 is arranged on the heat dissipation base 3. The light-emitting side of the reflector 1 is away from the heat dissipation base 3. One side of the heat dissipation base 3, which is in contact with the reflector 1, is thermally coupled to the reflector 1. The elastic element 4 is fixed to one end of the light source 2 and configured to movably fix the light source 2 on the reflector 1. The elastic element 4 is arranged on each of the two sides of the reflector 1 along the length of the reflector 1. The bracket 5 is firmly connected to the heat dissipation base 3 by snap fasteners. The elastic element 4 is arranged between the heat dissipation base 3 and the bracket 5.The bracket 5 abuts the elastic element 4 in a direction perpendicular to the length of the light source 2, thus fixing the light source 2 relative to the reflector 1 or the heat dissipation base 3. The heat dissipation base 3 and the bracket 5 together fix the reflector 1, allowing the light source 2 to be stably positioned on the reflector 1. The heat dissipation base 3 and the bracket 5 can be arranged to ensure the stability of the hair removal device. The elastic element 4 exhibits good elasticity. When the bracket 5 rests against the elastic element 4, the elastic element 4 can be slightly deformed. This prevents the light source 2 and the reflector 1 from easily vibrating relative to each other, thereby improving the light emission effect. Furthermore, the elastic element 4 can absorb the pressure exerted by the bracket 5 on the end of the light source 2.The elastic element 4 can flexibly come into contact with the end of the light source 2, so that damage to the light source 2 can be effectively reduced and the service life of the light source 2 can be extended.

[0280] In some embodiments, as in Fig. Figure 33 shows that the hair removal device further comprises a carbon-containing layer 91 arranged in the reflector 1. For example, the carbon-containing layer 91 can be arranged on a side of the reflector 1 facing away from the light source 2. The light source 2 can generate heat during use, and this heat can accumulate in the reflector 1. The carbon-containing layer 91 has excellent thermal conductivity, so the heat conduction rate of the reflector 1, in which the carbon-containing layer 91 is arranged, can be increased, and the heat dissipation performance of the reflector 1 can be improved. This can prevent the hair removal device from being damaged by the high temperature and prevent irritation or damage to the user's skin.

[0281] In some embodiments, the carbon-containing layer 91 is arranged on the heat dissipation base 3. For example, the carbon-containing layer 91 can be arranged between the heat dissipation base 3 and the reflector 1 to accelerate the heat conduction rate between the heat dissipation base 3 and the reflector 1.

[0282] In some embodiments, the carbon-containing layer 91 can be arranged on an exposed surface of the heat dissipation base 3 to improve the heat dissipation performance of the heat dissipation base 3.

[0283] In some embodiments, the carbon-containing layer 91 can consist of graphene, graphite powders, a graphite foil, a graphite film and the like, and can be arranged at any available position as described in the present disclosure by plating, spraying, attaching, etc.

[0284] In some embodiments, the heat dissipation base 3 can be a ceramic base. The ceramic base is configured with a first groove body 31. The reflector 1 is embedded in the first groove body 31. The first groove body 31 is strip-shaped, and one end of the groove body 31 may have a curved region. The reflector 1 is embedded in the first groove body 31. On the one hand, the contact area between the reflector 1 and the heat dissipation base 3 is increased, with the heat dissipation base 3 conducting heat to dissipate heat from the reflector 1, thereby reducing the heat radiation of the entire hair removal device. On the other hand, the first groove body 31 is positioned on the heat dissipation base 3. The space utilization of the heat dissipation base 3 can be improved, and the components within the hair removal device can be arranged more compactly.Furthermore, the ceramic is an insulator, so no short circuit can occur when the ceramic base comes into contact with the reflector 1. The reflector 1 is the conductor and is spaced away from the light source 2, so that when a power supply is applied, a strong electric field is generated which excites the light source 2 to emit light. Therefore, the body of the light source 2 is suspended in the cavity of the reflector 1.

[0285] In some embodiments, each of the two sides of the heat dissipation base 3 is provided with a first fastening section 32, and the first fastening section 32 and the heat dissipation base 3 can be formed as a single-piece structure. Each of the two sides of the bracket 5 is provided with a second fastening section 51, and the second fastening section 51 and the bracket 5 can be formed as a single-piece structure. The first fastening section 32 can correspond to the second fastening section 51. When connecting the heat dissipation base 3 to the bracket 5, the first fastening section 32 can be firmly attached to the second fastening section 51. In this way, the heat dissipation base 3 and the bracket 5 can be stably connected to each other, thereby improving the stability of the hair removal device.In some embodiments, the first fastening section 32 can be a buckle block or a cantilever hook, and the second fastening section 51 can be a fixing hole. When connecting the heat dissipation base 3 to the bracket 5, the cantilever hook can be inserted into the fixing hole. Once the cantilever hook is inserted into the fixing hole, a wall of the fixing hole can confine the cantilever hook and prevent it from easily slipping out. In this way, the first fastening section 32 and the second fastening section 51 can be stably connected to each other; that is, the heat dissipation base 3 and the bracket 5 can be fixed together, effectively preventing the heat dissipation base 3 from detaching from or falling off the bracket 5, and improving the stability of the hair removal device.

[0286] In some embodiments, the bracket 5 defines a window 52. The size of a portion of the window 52 corresponding to the second mounting section 51 is larger than the size of a portion of the ceramic base associated with the first mounting section 32, such that the portion of the ceramic base associated with the first mounting section 32 is embedded in the window 52 of the bracket 5. When assembling the ceramic base with the bracket 5, a side of the ceramic base near the bracket 5 can be embedded in the window 52, ​​thus making the connection between the ceramic base and the bracket 5 more stable. Furthermore, the gap between the ceramic base and the bracket 5 can be reduced, thereby reducing the heat that can be radiated from the reflector 1 to its edge, thus improving the performance of the hair removal device.

[0287] As in Fig. 31, Fig. 32 and Fig. As shown in Figure 34, the hair removal device can further comprise a side reflection element 6 arranged at each of the two ends of the reflector 1 along a longitudinal direction of the reflector 1. The side reflection element 6 can reflect light exiting the two ends of the reflector 1 onto the light-emitting side of the reflector 1. The side reflection element 6 completely reflects the light emitted by the light source 2 in order to improve the light utilization rate.

[0288] In some embodiments, the side reflection element 6 defines a through-hole 61. The diameter of the through-hole 61 is larger than the diameter of the lamp's end. The lamp's end can pass through the through-hole 61. In one arrangement, the lamp can pass through one of two through-holes 61 in the two side reflection elements 6. Alternatively, the lamp can pass through the through-hole 61 from the inside of the reflector 1, thus facilitating easy lamp placement. In some embodiments, the elastic element 4 can be a silicone cover or a soft rubber cover. In the present embodiment, the silicone cover can be used as an example for illustration, but the present disclosure does not limit the detailed material of the elastic element 4. The light source 2 can be a lamp, and the lamp can be strip-shaped or cylindrical.At each of the two ends of the lamp, a mounting post 21 is arranged, extending from the lamp. The radius of the mounting post 21 is smaller than the radius of the lamp. Specifically, the silicone cover can be cylindrical and define a mounting slot 41. The two ends of the lamp can be embedded in the mounting slot 41. The silicone cover defines a fixing hole 42 along an axis of the cover. The fixing hole 42 communicates with the mounting slot 41. The mounting post 21 can pass through the fixing hole 42.

[0289] The defined through-hole 61 allows the lamp to be precisely positioned on the reflector 1, reducing the time required for lamp placement and thus improving assembly efficiency. When the reflector 1 and lamp are assembled, one opening of the mounting slot 41 faces the reflector 1, and the two ends of the lamp are inserted into the mounting slot 41 by passing through the two through-holes 61. The silicone cover elastically presses the lamp against a wall of the through-hole 61 near the bottom of the reflector 1, reducing rigid contact between the lamp and the side reflector 6 and minimizing collisions between the side reflector 6 and the lamp.Even if the side reflection element 6 collides with the lamp, the silicone cover can cushion the collision force, effectively extending the lamp's lifespan and reducing usage costs.

[0290] As in Fig. 31, Fig. 32 and Fig. As shown in Figure 34, the two ends of the ceramic base, which are provided with the first groove body 31, are each additionally provided with two second groove bodies 33. The second groove bodies 33 are configured to accommodate the two ends of the light source 2 and the corresponding elastic elements 4. This saves space and improves the utilization of the ceramic base. Furthermore, the second groove body 33 reduces the risk of the end of the light source 2 and the elastic element 4 colliding with foreign objects. The interiors of the second groove bodies 33 and the interior of the first groove body 31 are interconnected. The depth of the second groove body 33 is greater than the depth of the first groove body 31.The second groove body 33 defines the space for accommodating the elastic deformation of the elastic element 4, preventing the elastomer 4 from being compressed against a wall of the second groove body 33. This allows the elastic element 4 to deform easily, adapting to the actual situation. During deformation, the elastic element 4 absorbs the external force, preventing the mounting post 21 from being easily damaged or broken. This reduces the number of replacement cycles for the light source 2, lowers operating costs, and improves the practicality of the hair removal device.

[0291] As in Fig. 31, Fig. 32 and Fig. As shown in Figure 34, in some embodiments the hair removal device may have a first translucent body 7, which is arranged on the light-emitting side of the reflector 1 and fixed to the support 5. The first translucent body 7 and the reflector 1 together define a cavity for receiving the light source 2. The first translucent body 7 may be a filter. The filter 7 can filter the light to select light with a wavelength suitable for removing hair from the skin. In this way, during operation of the hair removal device and when the light source 2 shines onto the skin, damage to the skin caused by the light can be reduced and the safety of hair removal can be improved.

[0292] In some embodiments, the hair removal device may have a second translucent body 8. The second translucent body 8 may be square or rectangular and embedded in the window 52. The second translucent body 8 is arranged on a side of the filter facing away from the light source 2. The second translucent body 8 has a light-incidence surface 81 facing the light source 2 and a light-emitting surface 82 facing away from the light source 2. In some embodiments, the second translucent body 8 may be a crystal. Alternatively, the second translucent body 8 may be a diamond. In the present embodiments, the second translucent body 8, which is the crystal, can be taken as an example. While the hair removal device is in operation, the light source 2 emits light, and the light is reflected by the reflector 1.The light continues to pass through the filter and is reflected to reach the crystal. The light enters the crystal from the light-incidence surface 81. The light can be reflected by the crystal itself and exits the crystal from the light-emission surface 82. The light emitted from the light-emission surface 82 can illuminate an area of ​​skin where the hair to be removed is located, thus removing it.

[0293] In some embodiments, the hair removal device includes a cooling element 9. One cooling side of the cooling element 9 can be thermally coupled to the other side of the heat dissipation base 3 to cool the space inside the reflector 1. The cooling element 9 can be, for example, a TEC cooling sleeve or a cooling block. The cooling element 9 can cool the heat dissipation base 3 to dissipate heat from the heat dissipation base 3 quickly and efficiently, thus enabling rapid cooling of the reflector 1. In the present embodiment, the cooling element 9 can be the TEC cooling plate and is shown below as an example. The present disclosure does not limit the detailed structure of the cooling element 9.

[0294] While the hair removal device is in operation, the light source 2 emits a large amount of light within the reflector 1, and the heat generated by this light can accumulate in the cavity. Furthermore, the temperature of the reflector 1 can increase as the heat accumulates in the cavity. One side of the heat dissipation base 3 is thermally coupled to the reflector 1, and the other side of the heat dissipation base 3 is thermally coupled to the cooling element 9. This thermal coupling can be achieved through any combination of heat transfer, thermal convection, and thermal radiation. That is, the heat from the reflector 1 can be dissipated via the heat dissipation base 3, and the heat in the cavity can be dissipated, thus cooling the reflector 1 and the cavity and improving the efficiency of heat dissipation from the light source 2.The configuration of the body of the light source 2, which is suspended in the cavity, allows for more even heat dissipation and improves its lifespan. Specifically, the heat generated during operation of the light source 2 can be dissipated by radiation in all directions. Furthermore, the air is evenly distributed around the light source 2, ensuring complete contact and uniform heat dissipation. The heat generated by the light source 2 is transferred through the cavity to the reflector 1 and the first translucent body 7, and then dissipated from the device. Additionally, the cooling element 9 conducts heat away from the heat dissipation base 3 for rapid heat dissipation, thus improving the heat dissipation efficiency of the hair removal device.Furthermore, the heat in the cavity, which can be transferred to other components of the hair removal device, can be reduced. During operation of the hair removal device, the burning sensation on the skin being treated can be reduced, and the performance of the device can be improved.

[0295] In some embodiments, a carbon-containing layer can be arranged on one side of the cooling element 9 facing the heat dissipation base 3 or an exposed surface of the cooling element 9. The carbon-containing layer 91 exhibits excellent thermal conductivity. Therefore, the cooling effect of the cooling element 9 can be improved, allowing the heat from the heat dissipation base 3 to be dissipated quickly and efficiently, thus rapidly cooling the reflector 1.

[0296] According to the embodiments described above, a hair removal device is provided comprising a reflector 1 and a light source 2. The light source 2 is a strip-shaped gas excitation light source and is arranged on the reflector 1. The distance between the body of the light source 2 and the reflector 1 is less than or equal to 0.3 mm. Therefore, after power is supplied, the reflector 1 generates a high voltage to ionize the gas in the light source 2 and produce an arc discharge, enabling the light source 2 to emit light. The reflector 1 is a conductor and defines a space in which the high voltage can be generated. By defining the distance between the light source 2 and the reflector 1, the voltage in the reflector 1 excites the light source 2 to emit light.In contrast to using a trigger wire to activate the lamp, in the present embodiment the reflector 1 activates the lamp without a trigger wire. This improves the way the lamp is activated, reduces the material required for its manufacture, and lowers manufacturing costs.

[0297] As in Fig. 35 shown, is Fig. Figure 35 shows a schematic structural view of the hair removal device according to an embodiment of the present disclosure. The hair removal device may have a head section 111 and a hand section 112 connected to the head section 111. The head section 111 is provided with a cold-compression section 1111, which is configured to be applied to the skin. The cold-compression section 1111 can emit light to irradiate a hair follicle in the skin. The light can penetrate the skin to irradiate the hair follicle and remove the hair. In addition, the cold-compression section 1111 can rapidly cool the skin to reduce skin burns from the light. In this way, the user can experience a comfortable sensation during the use of the hair removal device.In some embodiments, the cold compression section 1111 can emit light for skin care, so that the hair removal device can remove hair and perform skin care simultaneously.

[0298] As in Fig. 40 and Fig. As shown in Figure 41, in a further embodiment of the hair removal device, an elastic sealing ring 16 is arranged between the first translucent body 7 and the second translucent body 3. The elastic sealing ring 16 can be annular. The first translucent body 7 and the second translucent body 3 can be sealed by the elastic sealing ring 16. In this way, condensation cannot form between the second translucent body 3 and the first translucent body 7. No dirt can penetrate the connection between the second translucent body 3 and the first translucent body 7. The elastic sealing ring 16 is preferably annular.

[0299] If the hair removal device falls to the ground, the second translucent body 3 can, of course, collide hard with the ground. A conventional translucent body 3 can transmit an impact to the first translucent body 7, causing the first translucent body 7, the reflector 1, and the light source 2 to vibrate and potentially be damaged. In the hair removal device of the present embodiment, the impact force can be eliminated by the elastic sealing ring 16 when the second translucent body 3 impacts the ground.Due to the elasticity of the elastic sealing ring 16, it can deform elastically under external forces, thereby reducing or eliminating the impact between the first translucent body 7 and the second translucent body 3 and reducing the likelihood of damage to the first translucent body 7, the reflector 1, and the light source 2 from the impact force. This improves the collision resistance of the hair removal device.

[0300] As in the Fig. As shown in Figures 42 to 44, the elastic sealing ring 16 has an inner ring 161 that transmits light. After being filtered through the first transparent body 7, the light can be guided through the inner ring 161 to the second transparent body 3 and then shine onto the user's skin.

[0301] In the present embodiment, the first translucent body 7 and the second translucent body 3 can be fixed directly to the holder 6. The first translucent body 7 and the second translucent body 3 cannot move relative to the holder 6. Therefore, during use of the hair removal device, it is prevented that the second translucent body 3 moves backward relative to the holder 6 due to a human bone or a sharp object striking it. This prevents the first translucent body 7 or the hair removal device 100 from being irreparably deformed by compression. The elastic sealing ring 16 can be irreparably deformed by repeated compression. In this way, the light transmission efficiency of the hair removal device is not impaired, and a waste of light energy is avoided.

[0302] The elastic sealing ring 16 further defines a mounting groove 162, which communicates with an opening in the inner ring 161. The mounting groove 162 is defined on a side of the elastic sealing ring 16 facing away from the hair removal device 100. The inner ring 161 extends from a bottom wall of the mounting groove 162 to the first translucent body 7. The second translucent body 3 is partially received in the mounting groove 162 to improve the sealing effect between the second translucent body 3 and the elastic sealing ring 16 and to fix the elastic sealing ring 16 to the second translucent body 3, thus creating a secure connection between the elastic sealing ring 16 and the second translucent body 3.

[0303] In some embodiments, the elastic sealing ring 16 can have an outer ring 163 and a projection 164 located on one side of the outer ring 163. The projection 164 can abut the first translucent body 7. One side of the outer ring 163 facing away from the projection 164 defines the mounting groove 162. The inner ring 161 extends from the bottom wall of the mounting groove 162 to the projection 164. The outer ring 163 and the projection 164 can each have a fully closed loop structure. Light within the inner ring 161 can only escape outwards from the second translucent body 3.

[0304] In some embodiments, the cross-section of the projection 164 can be a transversely oriented triangle. The contact area between the projection 164 and the first translucent body 7 can be smaller than the contact area between the projection 164 and the outer ring 163. Therefore, when the elastic sealing ring 16 is in place, the end of the projection 164 facing away from the outer ring 163 can be partially corrugated after compression. Since the elastic sealing ring 16 is elastic, a corrugated portion of the elastic sealing ring 16 can bear firmly against the first translucent body 7. That is, if the distance between the second translucent body 3 and the first translucent body 7 changes slightly, the elastic sealing ring 16 can be adjusted by adjusting the corrugated portion to accommodate the change in distance.In this way, a tight fit or even an interference fit can be maintained at all times between the elastic sealing ring 16 and the second translucent body 3, as well as between the elastic sealing ring 16 and the first translucent body 7, thereby achieving a better sealing effect. In other embodiments, the cross-section of the projection 164 can be trapezoidal.

[0305] In the present embodiment, the elastic sealing ring 16 can be a ring made of a laser-resistant, high-temperature-resistant and low-temperature-resistant material, so that when using the elastic sealing ring 16, it can be prevented that the elastic sealing ring 16 deforms due to high or low temperatures or laser irradiation, thereby increasing the service life of the elastic sealing ring 16.

[0306] In some embodiments, the hand section 112 may have a housing that defines a space in the center (not marked in the drawings). A surface of the housing may define a vent opening 1211. The vent opening 1211 may be connected to an interior and an exterior of the housing, allowing the hair removal device to exchange air with the outside environment via the vent opening 1211 and thus reducing the temperature inside the device. The housing may further include an interface 1212 configured for connection to an external power supply for charging the hair removal device. The present disclosure does not limit the position of the interface 1212 on the housing.

[0307] As in Fig. 35 and Fig. 36 shown, is Fig. 36 An exploded view of the device according to one embodiment of the present disclosure. An arrow in Fig. Figure 36 shows a direction of airflow within the hair removal device, driven by a cold drive assembly. A straight line represents the direction in which cold air flows, and a wavy line represents the direction in which hot air flows. Specifically, the hair removal device may comprise the housing, a light cover 113 arranged over an opening in the housing, a hair removal mechanism 14 contained within the housing, and a bottom cover 15.

[0308] In the present embodiment, the housing can comprise a first housing 121 and a second housing 122. The first housing 121 and the second housing 122 can be interlocked to define a cavity and two openings at two ends of the housing. The hair removal mechanism 14 is accommodated in the cavity, and the light cover 113 and the bottom cover 15 are arranged to cover the two openings, respectively, to close the openings defined by the first housing 121 and the second housing 122 after the first housing 121 and the second housing 122 have been interlocked to define the cavity.

[0309] In some embodiments, the first housing 121, the second housing 122, the light cover 113 and the bottom cover 15 can be connected by snap fasteners, screws, adhesives, etc.

[0310] The hair removal mechanism 14 can include the hair removal assembly 100, the cold compression assembly 200, the heat dissipation assembly 300 and the cold drive assembly 400.

[0311] The cold compression assembly 200 is located near the light cover 113. The light cover 113 may have a through-hole (not marked in the drawings). A portion of the cold compression assembly 200 is exposed through the through-hole in the light cover 113 to make direct contact with the skin. It is understood that this portion of the cold compression assembly 200 and the light cover 113 together form the head section 111 of the hair removal device.

[0312] The hair removal device 100 is located on one side of the cold compression assembly 200, facing away from the light cover 113, and is configured to emit light onto the cold compression assembly 200. The light can be visible light, such as red, green, or yellow light. Once the light enters the cold compression assembly 200, it can pass through it to penetrate further into the skin and reach the hair follicle beneath the skin to remove hair.

[0313] The heat dissipation assembly 300 is arranged on one side of the cold compression assembly 200 and connected to it. When applied to the skin, the cold compression assembly 200 can absorb heat from the skin to lower its temperature and reduce the risk of burns. However, the temperature of the cold compression assembly 200 can rise with prolonged use, potentially reducing its cooling effect. The heat dissipation assembly 300 absorbs this heat, allowing the cold compression assembly 200 to continue operating at a lower temperature, thus ensuring that the cold compression assembly 200 continues to cool the skin. Therefore, in this embodiment, the hair removal device can operate at a consistently low temperature during continuous use, preventing injury to the user.

[0314] The cooling drive assembly 400 is arranged on one side of at least one part of the heat dissipation unit 300 facing away from the hair removal unit 100 and is configured to dissipate heat from the hair removal unit 100 and the heat dissipation unit 300.

[0315] In the present embodiment, the cooling drive assembly 400 can accommodate an external cooling medium that passes through the vent opening 1211 and enters the interior of the hair removal device. The cooling medium can flow along the hair removal device 100 and the heat dissipation assembly 300 to dissipate heat and then exit the device through the vent opening 1211.

[0316] In some embodiments, the external cooling medium can be air. The cooling drive assembly 400 can draw in the air and blow it towards the hair removal assembly 100 and the heat dissipation assembly 300. The heat from the hair removal assembly 100 and the heat dissipation assembly 300 can be dissipated by the airflow.

[0317] In the present embodiment, the vent opening 1211 can be defined in the first housing 121, and at least a part of the refrigeration drive assembly 400 faces the vent opening 1211, so that the refrigeration drive assembly 400 can better absorb the external cooling medium entering the housing through the vent opening 1211, and the heat dissipation efficiency can be improved. In other embodiments, the vent opening 1211 can be defined in the second housing 122.

[0318] As in Fig. 36 and Fig. 37 shown, is Fig. 37 an exploded view of the in Fig. Structure shown in 36, where the arrows are in Fig. 37 can indicate the direction in which air is blown out of a fan.

[0319] In the present embodiment, the hair removal device can further comprise a holder 500, a circuit board 600, a processor 700, and a capacitor 800. The hair removal assembly 100 and the cold compression assembly 200 can be arranged within the holder 500, and the cold drive assembly 400 can be arranged adjacent to the holder 500. The hair removal assembly 100, the cold compression assembly 200, and the cold drive assembly 400 can be mounted on the circuit board 600 and electrically connected to it.

[0320] The processor 700 and the capacitor 800 can be electrically connected to and mounted on the circuit board 600. When an external power supply is connected, it can charge the capacitor 800, which can then power the hair removal device. Furthermore, the capacitor 800 can store energy when connected to the external power supply, allowing the hair removal device to be used even without the external power supply. The processor 700 can send control commands to the hair removal assembly 100, the cold compression assembly 200, and the cold drive assembly 400 to control the operation of the hair removal device.For example, the hair removal device can be controlled to turn on and off, the heat protection of the hair removal device can be controlled, the power of the hair removal device can be adjusted, and so on.

[0321] In the present embodiment, the printed circuit board 600 can be fixed in the second housing 122, and the printed circuit board 600 can be a PCBA printed circuit board.

[0322] In the prior art, the heat inside the hair removal device can continuously increase during use. Circuits and components inside the hair removal device can explode, burn out, short-circuit, etc., when operating at high temperatures. In the present embodiment, the cooling drive assembly 400 can dissipate heat from the hair removal assembly 100 and the heat dissipation assembly 300, and the heat dissipation assembly 300 can dissipate heat from the cold compression assembly 200, so that the cold compression assembly 200 can compress the skin to cool it, making the skin feel comfortable and preventing the components from exploding, burning out, short-circuiting, etc.

[0323] Specifically, the hair removal device 100 can comprise a light source 101, a reflector 102, a filter 103 and two electrodes 104.

[0324] The light source 101, the reflector 102, and the filter 103 are arranged within the holder 500; that is, the holder 500 is configured with mounting positions for the light source 101, the reflector 102, and the filter 103. The light source 101, the reflector 102, and the filter 103 can be snapped into the mounting positions in the holder 500 accordingly.

[0325] The light source 101 can be positioned opposite the cold compression assembly 200. The light emitted by the light source 101 can be directed straight into the cold compression assembly 200. The reflector 102 can be positioned on the side of the light source 101 facing away from the cold compression assembly 200 and can reflect the light from the light source 101 into the cold compression assembly 200 to prevent loss of light energy. The filter 103 is positioned between the light source 101 and the cold compression assembly 200. That is, the light source 101, the filter 103, and the cold compression assembly 200 can be arranged sequentially in the direction of light propagation. The filter 103 is configured to filter out a portion of the harmful light emitted by the light source 101, thus reducing light-induced skin damage and increasing the safety of hair removal.The two electrodes 104 can be connected to two sides of the light source 101 and electrically connected to the circuit board 600 to transmit electrical signals.

[0326] In some embodiments, the light source 101 can be a lamp, and the color of the light emitted by the lamp is not limited. The lamp can emit colored light, compound light, etc. The wavelength and frequency of the light can be set as required. The type of lamp is not limited. The lamp can be a xenon semiconductor lamp, a quartz lamp, a laser lamp, etc. The type of light can be intense pulsed light (IPL), deep pulsed light (DPL), optimal pulse technology (OPT), advanced optimal pulse technology (AOPT), broadband light (BBL), etc. The type of light can be determined based on the desired effects.

[0327] In some embodiments, the reflector 102 can be a U-shaped reflector surrounding the light source 101. Furthermore, an opening of the U-shaped reflector can face the cold compression assembly 200 and reflect light that does not enter the cold compression assembly 200 back to it. In addition, the reflector 102 can prevent the heat generated by the light source 101 from being transferred to other components of the hair removal device. In the present embodiment, the holder 500 can have a fixing frame 550 and a tube 560. The fixing frame 550 can define a first receiving space 510 and a second receiving space 520. The first receiving space 510 is configured to receive the hair removal assembly 100. The second receiving space 520 is configured to receive the cold compression assembly 200.The first recording chamber 510 can be adjacent to the second recording chamber 520 to reduce the distance between the hair removal device 100 and the cold compression assembly 200, thereby reducing the loss of light emitted by the hair removal device 100. The second recording chamber 520 can be located closer to the head section 111 of the [unit / device]. Fig. The hair removal device shown in 21 is located in the first recording room 510.

[0328] When the hair removal device is in operation, the light source 101 can generate a large amount of heat, which can irradiate the reflector 102 and the filter 103, thus increasing their temperature. Therefore, the heat from the light source 101, the reflector 102, and the filter 103 must be dissipated.

[0329] In the present embodiment, the bracket 500 can comprise the fixing frame 550 and the tube 560. One end of the tube 560 can be connected to one side of the fixing frame 550, and the other end of the tube 560 can extend to the refrigeration drive assembly 400. The fixing frame 550 defines an air outlet 540 that communicates with the first receiving chamber 510, and the tube 560 defines an air inlet 530 that communicates with the first receiving chamber 510. The air inlet 530, the first receiving chamber 510, and the air outlet 540 can be sequentially connected to one another.

[0330] The air inlet 530 can be connected to the cooling arrangement 400. The air outlet 540 can be connected to the vent 1211. The cooling arrangement 400 can draw in outside air from the vent 1211 and blow the air towards the air outlet 540. The air flows through the air outlet 540 into the first receiving chamber 510 and dissipates heat from the light source 101, the reflector 102, and the filter 103 in the first receiving chamber 510. Furthermore, the air can flow out of the device through the air outlet 540 and the vent 1211 to dissipate the heat.

[0331] In some embodiments, part of the fixing frame 550 and part of the tube 560 form a first support 501, and the remaining part of the fixing frame 550 and the remaining part of the tube 560 form a second support 502. In other embodiments, the fixing support 550 can be designed as a one-piece structure.

[0332] The first bracket 501 and the second bracket 502 can be connected to each other via a snap-fit ​​connection. The first bracket 501 can be located near the first housing 121, and the second bracket 502 can be located near the second housing 122. The air outlet 540 can be defined in the first bracket 501 and can be located opposite the vent 1211 in the first housing 1211 to increase the heat dissipation efficiency at the air outlet 540. The first receiving chamber 510 can be defined in a portion of the first bracket 501 and a portion of the second bracket 502. This portion of the first bracket 501 and the portion of the second bracket 502 can correspond to the fixing frame 550 and snap together. The air inlet 530 can be defined in another portion of the first bracket 501 and another portion of the second bracket 502.The other part of the first bracket 501 and the other part of the second bracket 502 can correspond to the tube 550 and be interlocked together. The air inlet 530 can be connected to the first receiving chamber 510 and to the refrigeration drive assembly 400. An interior of the bracket 6 can define a channel for directing an airflow, thereby directing the airflow from the refrigeration drive assembly 400 into the first receiving chamber 510.

[0333] Therefore, in the present embodiment, the hair removal assembly 100 can dissipate heat via the cooling drive assembly 400, thus ensuring that the hair removal device can be used safely.

[0334] Furthermore, in the present embodiment, the cold compression assembly 200 can have a second translucent body 201 and a cooling element 202.

[0335] The second translucent body 201 can be configured to be attached to the skin. The second translucent body 201 can face the light source 2. The second translucent body 201 can be a light-transmitting element. The light emitted by the light source 101 enters the second translucent body 8 and passes through it to reach the skin.

[0336] In some embodiments, the second transparent body 201 can be a light-conducting crystal, such as sapphire, K9 glass, or crystal glass. If the second transparent body 201 is made of sapphire, it can exhibit excellent thermal conductivity.

[0337] In some embodiments, the second translucent body 201 can be cylindrical or cuboid. A surface of the second translucent body 201 facing away from the light source 2 can be configured so that it can be attached to the skin.

[0338] The cooling element 202 can be connected to the second translucent body 201 to absorb heat from it. Since the temperature of the second translucent body 201 increases when it comes into contact with the skin, the cooling element 202 can absorb this heat, keeping the second translucent body 201 cool. Furthermore, if the second translucent body 201 remains in contact with the skin for an extended period, it can continue to cool the skin, thereby reducing any burning sensation.

[0339] Furthermore, the cooling element 202 can be a semiconductor cooling element. One end of the cooling element 202, which absorbs heat, can be connected to the second translucent body 201, and the other end of the cooling element 202 can dissipate the heat.

[0340] In order to dissipate heat from the heat dissipation end of the cooling element 202, in the present embodiment the heat dissipation assembly 300 is connected to the heat absorption end of the cooling element 202 and absorbs the heat from the cooling element 202.

[0341] Specifically, the heat dissipation assembly 300 can comprise a heat dissipation plate 301 and a heat dissipation wing 302. One surface of the heat dissipation plate 301 has a first region 310 and a second region 311, which are arranged side by side. The hair removal device 100 is arranged in the first region 310, and the heat dissipation wing 302 is arranged in the second region 311. The second region 311 is arranged on one side of the fixing frame 550, which is connected to the tube 560. The heat dissipation wing 302 and the tube 560 are arranged side by side on one side of the fixing frame. The fixing frame 550 is arranged in the first region 310. The heat dissipation plate 301 is arranged on the circuit board 600 and connected to the cold compression assembly 200. Specifically, the cooling element 202 can be connected to the heat dissipation plate 301 by means of a thermally conductive silicone grease.The cold compression assembly 200 can quickly transfer heat to the heat dissipation plate 301 via the thermally conductive silicone grease. The heat dissipation vane 302 can dissipate heat from the heat dissipation plate 301 and assist the heat dissipation plate 301 in this process, enabling the heat dissipation plate 301 to continuously absorb heat from the cooling element 202.

[0342] In some embodiments, the number of heat dissipation wings 302 can be more than one. The additional heat dissipation wings 302 can be parallel to each other and attached to the heat dissipation plate 301 by welding.

[0343] In some embodiments, a surface of the heat dissipation wing 302 can be sprayed with a thermally conductive paint. The thermally conductive paint can radiate heat away from the heat dissipation wing 302 and prevent the heat dissipation wing 302 from being affected by water, corroding, and wearing down.

[0344] In the present embodiment, the heat dissipation plate 301 can be a temperature-homogeneous plate. When a liquid within the temperature-homogeneous plate comes into contact with a high-temperature environment, the liquid can absorb heat and evaporate into a gas. When the gas comes into contact with a low-temperature environment, the gas can release heat and condense back into a liquid. Therefore, the temperature of a surface of the temperature-homogeneous plate can be kept homogeneous due to periodic evaporation and condensation. Thus, part of the surface of the heat dissipation plate 301 is connected to the cooling element 202, and the other part is connected to the heat dissipation vane 302, so that the heat generated by the cooling element 202 can be dissipated via the heat dissipation plate 301 and the heat dissipation vane 302.

[0345] In some embodiments, such as in Fig. As shown in Figure 38, the carbon-containing layer 92 can be arranged between the second transparent body 201 and the heat dissipation assembly 300, for example on a surface of the heat dissipation plate 301 that is thermally coupled to the second transparent body 201. The carbon-containing layer 92 has excellent thermal conductivity and can accelerate the heat conduction rate of the heat dissipation plate 301 and improve the heat dissipation performance of the heat dissipation assembly 300.

[0346] In some embodiments, the carbon-containing layer can be a graphene material, graphite powder, a graphite foil, or a graphite film.

[0347] In some embodiments, the carbon-containing layer can be arranged by plating, spraying, or bonding.

[0348] To improve the heat dissipation performance of the heat dissipation assembly 300, the heat dissipation assembly 300 can also be connected to the refrigeration drive assembly 400 in the present embodiment.

[0349] Specifically, the heat dissipation vane 302 of the heat dissipation assembly 300 can be connected to the refrigeration drive assembly 400. The refrigeration drive assembly 400 can draw in outside air through the vent opening 1211 and direct the air towards the heat dissipation vane 302. The air can then flow along the heat dissipation vane 302 to dissipate heat from it.

[0350] In one example, the heat dissipation vane 302 can be arranged parallel to an airflow direction driven by the refrigeration drive assembly 400 in order to increase a contact area between the heat dissipation vane 302 and the airflow, thereby increasing the efficiency of heat dissipation from the heat dissipation vane 302.

[0351] The heat dissipation vane 302 can face the vent opening 1211 in the first housing 121. After flowing along the heat dissipation vane 302, the airflow can quickly exit the device through the vent opening 1211.

[0352] Therefore, the cooling drive assembly 400 of the present embodiment can drive the cooling medium to dissipate heat from the hair removal assembly 100 and can further dissipate heat from the heat dissipation base 300. With improved safety, the irradiated skin can be compressed for cooling, and the risk of skin burns can be reduced. Furthermore, the cooling compression assembly 200 can be controlled by the heat dissipation assembly 300 and the cooling drive assembly 400 to reach a low temperature of approximately zero degrees. In this way, the skin near a light exit aperture can approach the freezing point extremely closely, the burning sensation on the skin can be reduced, and brief contact between the skin and the device cannot cause skin damage.

[0353] As in Fig. 36, Fig. 37 and Fig. 39 shown, is Fig. 39 A schematic structural view of an air outlet of a fan housing of the in Fig. 37. In the present embodiment, the refrigeration drive assembly 400 can comprise a fan housing 401 and a fan 402. The fan housing 401 is arranged on one side of the heat dissipation assembly 300 that is away from the refrigeration compression assembly 200, and the fan 402 is accommodated inside the fan housing 401.

[0354] An air inlet end of the fan 402 faces the vent opening 1211 in the first housing 121. The fan 402 drives the outside air to flow through the vent opening 1211 into the fan 402. The fan housing 401 defines an air outlet 410 for discharging air. An air outlet end of the fan 402 is connected to the air outlet 410. The fan 402 drives the outside air to flow through the vent opening 1211 into the fan 402 and further drives the air to flow out through the air outlet 410.

[0355] In some embodiments, the fan 402 can be a radial fan, an axial fan, a mixed-flow fan or a cross-flow fan.

[0356] Furthermore, the air outlet 410 can have a first air outlet 411 and a second air outlet 412. The air at the air outlet 410 of the fan 402 can be divided into two parts. One part of the air flows out of the device through the first air outlet 411, and the other part of the air flows out of the device through the second air outlet 412.

[0357] In some embodiments, the air outlet 410 may further comprise a third air outlet or multiple air outlets. The present disclosure does not limit the number of air outlets.

[0358] In the present embodiment, the first air outlet 411 is connected to the air inlet 530 of the bracket 500. The fan 402 drives the outside air to flow into the fan 402 through the vent 1211. The fan 402 drives the air to flow from the first air outlet 411 and the air inlet 530 into the first receiving chamber 510. The air in the first receiving chamber 510 can dissipate heat from the light source 2, the reflector 1, and the filter 103. Finally, the air flows out of the device through the air outlet 540 and the vent 1211. In this way, the heat is dissipated to the outside, thus dissipating the heat from the hair removal device 100.

[0359] In the present embodiment, the second air outlet 412 is connected to the heat dissipation vane 302 of the heat dissipation assembly 300. The fan 402 drives the outside air so that it enters the fan 402 from the vent opening 1211. The fan 402 drives the air to flow through the second air outlet 412 between each pair of the multiple heat dissipation vanes 302 of the heat dissipation assembly 300. The air flows along the heat dissipation vanes 302, conducts the heat away from the heat dissipation vanes 302, and then flows out of the device through the air outlet 1211. Once the temperatures of the heat dissipation vanes 302 have decreased, the heat from the heat dissipation plate 301 can be reduced accordingly. In this way, the heat dissipation plate 301 can absorb the heat from the cold compression assembly 200, thereby dissipating the heat from the cold compression assembly 200.

[0360] In some embodiments, the amount of air flowing into the first air outlet 411 and the second air outlet 412 is not limited and can be determined as needed. The amount of air flowing into the first air outlet 411 and the second air outlet 412 can be controlled by configuring the size of the first air outlet 411 and the size of the second air outlet 412. For example, in the present embodiment, the air outlet area of ​​the second air outlet 412 is larger than the air outlet area of ​​the first air outlet 411, so that a larger volume of air flows through the second air outlet 412 to improve the efficiency of heat dissipation from the heat dissipation plate 301.

[0361] According to the hair removal device in the present embodiment, the heat from the hair removal assembly 100, the cold compression assembly 200, and the heat dissipation assembly 300 can be dissipated by the cooling drive assembly 400, so that the heat from the hair removal assembly 100 and the cold compression assembly 200 can be dissipated simultaneously. The heat dissipation performance of the hair removal device can be improved, and the safety of the hair removal device can be enhanced. Furthermore, the skin, which is continuously compressed for cooling, can be brought extremely close to the freezing point, the burning sensation on the skin can be reduced, and the skin cannot be damaged during hair removal.

[0362] The above description shows only embodiments of the present disclosure and does not limit the scope of the present disclosure. Any equivalent structure or equivalent process transformation carried out on the basis of the specification and the accompanying drawings and applied directly or indirectly in other fields also falls within the scope of the present disclosure.
