DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] The terms "first", "second", "third" in the embodiments of the present application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second", "third" can expressly or implicitly include at least one of the features. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0040] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0041] Reference Figure 1 and Figure 2 The present application discloses a hair removal device, which includes a reflective cup 1, a light source 2, a first light-transmitting body 3, a heat dissipation base 4 and a refrigeration component 5. The light source 2 is assembled in the reflective cup 1, and can emit light, and the reflective cup 1 can reflect the light. The first light-transmitting body 3 is arranged on the light-emitting side of the reflective cup 1, and covers the light-emitting side of the reflective cup 1 and forms a cavity with the reflective cup 1 that can accommodate the light source 2. The reflective cup 1 is embedded in the heat dissipation base 4, and the side of the heat dissipation base 4 that contacts the reflective cup 1 is thermally coupled with the reflective cup 1. The refrigeration component 5 is installed on the heat dissipation base 4, and the refrigeration side of the refrigeration component 5 is thermally coupled with the side of the heat dissipation base 4 that contacts the refrigeration component 5. Among them, the main body of the light source 2 can be suspended in the cavity, and the refrigeration component 5 is used to cool the cavity.

[0042] When the hair removal device is working, the light source 2 emits a large amount of light in the reflective cup 1, and the heat generated by the light is accumulated in the cavity, and the temperature of the reflective cup 1 rises as the heat in the cavity accumulates. Among them, one side of the heat dissipation base 4 is thermally coupled with the reflective cup 1, and the refrigeration component 5 is thermally coupled with the other side of the heat dissipation base 4. The thermal coupling can achieve heat transfer through heat transfer, heat convection or heat radiation, or any combination of the above three methods. That is, the heat on the reflective cup 1 can be transferred out through the heat dissipation base 4, and the heat in the cavity can be dissipated at the same time, so as to cool the reflective cup 1 and the cavity, and improve the heat dissipation efficiency of the light source 2. By using the method of suspending the main body of the light source 2 in the cavity, the heat dissipation of the light source 2 can also be made more uniform, which is conducive to extending the service life of the light source 2. Specifically, the heat generated by the light source 2 when working is dissipated to the surroundings in the form of radiation, and the air medium is evenly wrapped around the light source 2, and while being in full contact with the light source 2, the heat generated by the light source 2 is also uniformly dissipated. Heat is generated by the light source 2, transferred to the reflective cup 1 and the first light-transmitting body 3 through the cavity, and then dissipated.

[0043] In addition, the heat on the heat dissipation base 4 can be further transferred out through the refrigeration component 5 to achieve the purpose of rapid heat dissipation, thereby improving the heat dissipation effect of the hair removal device, while reducing the heat radiation in the cavity to other parts of the hair removal device, so that during the use of the hair removal device, the burning sensation on the hair removal skin is reduced, thereby improving the performance of the hair removal device.

[0044] Optionally, the hair removal device may further include a carbon-containing layer disposed on the reflective cup 1. Figure 3 The carbon-containing layer 91 can be arranged on the side of the reflective cup 1 facing away from the light source 2. The light source 2 generates heat during use and accumulates in the reflective cup 1. The carbon-containing layer 91 has excellent thermal conductivity, which can accelerate the thermal conductivity of the reflective cup 1, enhance the heat dissipation performance of the reflective cup 1, prevent the hair removal device from being damaged due to excessive temperature, and prevent irritation or damage to the user's skin.

[0045] Optionally, the carbon-containing layer is disposed on the heat dissipation base 4. Figure 3 As shown, for example, it is arranged between the heat dissipation base 4 and the reflective cup 1 to accelerate the heat conduction rate between the heat dissipation base 4 and the reflective cup 1 .

[0046] Optionally, the carbon-containing layer can also be arranged on the side of the cooling element 5 facing the heat dissipation base 4 or on the exposed surface of the cooling element 5 to enhance the cooling effect of the cooling element 5 so as to promptly and quickly remove the heat on the heat dissipation base 4, so as to achieve the purpose of quickly dissipating the heat of the reflective cup 1.

[0047] Optionally, the carbon-containing layer may be a material such as graphene material, graphite powder, graphite sheet or graphite film, and may be disposed at the position where the carbon-containing layer may be disposed as described in the present application by means of plating, spraying or lamination.

[0048] Optionally, the heat dissipation base 4 may be a ceramic base or a base made of aluminum, and the heat dissipation base 4 is used to quickly dissipate heat from the reflective cup 1, so as to improve the heat dissipation effect of the reflective cup 1. For example, ceramics themselves have stable physical properties, such as corrosion resistance, thermal expansion and contraction, and ceramics absorb heat quickly, which enables the ceramic base to quickly absorb heat, and the reflective cup 1 and the cavity can be cooled by the ceramic base, thereby improving the heat dissipation effect of the hair removal device.

[0049] In addition, ceramic is an insulator, and ceramic will not cause a short circuit when in contact with the reflective cup 1. The ceramic base covers the outer surface of the reflective cup 1, reducing the risk of leakage of the hair removal device at the reflective cup 1 and improving the safety of the hair removal device. The main body of the light source 2 is suspended in the cavity, and there is a gap between the reflective cup 1 formed by the conductor. After power is turned on, a strong electric field is formed between the light source 2 and the reflective cup 1, thereby stimulating the light source 2 to emit light.

[0050] Among them, a groove body 41 is provided on one side of the ceramic base, and the groove body 41 is in a long strip shape. Optionally, the reflective cup 1 can be a semi-arc reflective cup, and the reflective cup 1 is embedded in the groove body 41. The first light-transmitting body 3 can be a filter or a transparent glass slide, and the first light-transmitting body 3 is fixed relative to the ceramic base. The heat generated by the light source 2 can be bound in the cavity by the first light-transmitting body 3 and the reflective cup 1 to reduce the possibility of heat radiation to other parts of the hair removal device. The groove body 41 is provided on the ceramic base, and the reflective cup 1 is embedded in the groove body 41, so as to increase the contact area between the ceramic base and the reflective cup 1, thereby improving the heat absorption capacity of the ceramic base to the reflective cup 1, so as to improve the heat dissipation effect of the reflective cup 1 and the cavity.

[0051] Optionally, the reflective cup 1 may be a long strip-shaped reflective cup.

[0052] Reference Figure 1 Optionally, the cooling element 5 may be a TEC cooling sheet or a cooling block, and the cooling element 5 is used to cool the heat dissipation base 4, so as to promptly and quickly remove the heat on the heat dissipation base 4, so as to achieve the purpose of quickly dissipating the heat from the reflective cup 1. In the example of the present application, the cooling element 5 used is a TEC cooling sheet, which is only an example and does not limit the cooling element 5.

[0053] Optionally, the heat sink 4 can be in the shape of a long strip, the TEC cooling sheet is in the shape of a long strip, the heat sink 4 is provided with a mounting groove, the mounting groove is located on the side of the heat sink 4 away from the opening of the reflective cup 1, the TEC cooling sheet is placed in the mounting groove, and the TEC cooling sheet is in full contact with the heat sink 4. The heat transferred from the cavity and the reflective cup 1 to the heat sink 4 can be quickly transferred by the TEC cooling sheet to achieve cooling of the heat sink 4. On the one hand, when the hair removal device is working, the light source 2 can be better protected, and the damage to the light source 2 caused by high temperature can be effectively reduced to increase the service life of the light source 2. On the other hand, the temperature of the outer surface of the hair removal device is reduced so that the user can hold the hair removal device comfortably, so as to improve the performance of the hair removal device.

[0054] Reference Figure 1 , Figure 2 and Figure 4 The hair removal device includes a bracket 6, which is used to assemble the reflective cup 1 and the first light-transmitting body 3 together with the heat dissipation base 4. The bracket 6 has a window 61, which is square or rectangular. The first light-transmitting body 3 is fixed to the bracket 6 and covers the window 61. The heat dissipation base 4 and the bracket 6 are detachably connected, so that the assembly and disassembly of the hair removal device are more convenient. The reflective cup 1 and the first light-transmitting body 3 can be fixed together by the bracket 6 and the heat dissipation base 4, so that the structure inside the hair removal device is more compact, the space inside the hair removal device is saved, the design is reasonable, and the hair removal device is convenient to use.

[0055] Optionally, both sides of the heat dissipation base 4 are integrally formed with a first buckle portion 42, and both sides of the bracket 6 are integrally formed with a second buckle portion 62, and the first buckle portion 42 and the second buckle portion 62 are arranged correspondingly. In the process of connecting the heat dissipation base 4 and the bracket 6 together, the first buckle portion 42 and the second buckle portion 62 are tightly buckled together, so that the heat dissipation base 4 and the bracket 6 can be stably connected together, thereby improving the use stability of the hair removal device.

[0056] Optionally, the first buckle portion 42 may be a block or a cantilever hook, and the second buckle portion 62 may be a fixing hole. The cantilever hook is embedded in the fixing hole, and after the cantilever hook is embedded in the fixing hole, the fixing hole can limit the cantilever hook from being easily detached from the fixing hole, so that the first buckle portion 42 and the second buckle portion 62 can be stably connected together, that is, the heat dissipation base 4 and the bracket 6 can be relatively fixed together, effectively preventing the heat dissipation base 4 and the bracket 6 from loosening or falling off, so as to improve the overall stability of the hair removal device.

[0057] Reference Figure 1 , Figure 2 and Figure 4 The bracket 6 is fixed with a second light-transmitting body 7, which is square or rectangular and is embedded in the window 61. The second light-transmitting body 7 is located on the side of the filter facing away from the light source 2, and has a light-entering surface 71 facing the light source 2 and a light-emitting surface 72 facing away from the light source 2. Optionally, the second light-transmitting body 7 can be a crystal, or a diamond, and a crystal is taken as an example in the application embodiment.

[0058] When the hair removal device is working, the light source 2 emits light, the reflective cup 1 reflects the light, and the light is reflected onto the crystal through the filter. The light enters from the light incident surface 71, and is reflected by the crystal body and then emitted from the light emitting surface 72. The light emitted from the light emitting surface 72 is irradiated on the skin part to be hair removed, so that the hair on the skin can be removed.

[0059] Optionally, the number of TEC cooling sheets can be two or three. For example, the number of TEC cooling sheets can be two, and the two TEC cooling sheets are arranged at intervals, wherein one TEC cooling sheet is fixed on the heat dissipation base 4, and the other is installed on the bracket 6. The bracket 6 is provided with an installation port, which is connected to the window 61. When the second light-transmitting body 7 is embedded in the window 61, the TEC cooling sheet is embedded in the installation port, and the TEC cooling sheet and the second light-transmitting body 7 are in contact with each other. The second light-transmitting body 7 is cooled by the TEC cooling sheet, so that the second light-transmitting body 7 can quickly dissipate heat, effectively reduce the temperature of the second light-transmitting body 7, and prevent the light-emitting surface 72 from getting hot as much as possible, so that the hair removal device can safely contact the skin part to be depilated, thereby improving the comfort of using the hair removal device.

[0060] Optionally, for example, the number of TEC cooling sheets can be three, wherein one TEC cooling sheet is fixed on the heat dissipation base 4, and the other two TEC cooling sheets are respectively embedded in the bracket, and the two TEC cooling sheets are respectively located on both sides of the second light-transmitting body 7, which can be the upper and lower sides of the second light-transmitting body 7 facing the direction of light emission, or the left and right sides. The TEC cooling sheets on both sides of the second light-transmitting body 7 can improve the cooling efficiency of the second light-transmitting body 7, so that the second light-transmitting body 7 can quickly dissipate heat, thereby achieving the purpose of cooling, thereby improving the heat dissipation effect of the hair removal device.

[0061] Reference Figure 5 Optionally, the structures and relative positions of the light source 2, the reflective cup 1, and the second light-transmitting body 7 satisfy the following conditions: the light uniformity of the light-emitting surface 72 is greater than or equal to 90%, or the light spot on the light-emitting surface 72 occupies at least 95% of the light-emitting surface 72. The light uniformity of the light-emitting surface 72 is greater than or equal to 90%, which can improve the hair removal effect of the hair removal device, so that the hair on the skin part to be removed can be removed evenly. Similarly, the light spot on the light-emitting surface 72 occupies at least 95% of the light-emitting surface 72, which can also make the hair on the skin part to be removed evenly, and can also improve the utilization rate of light.

[0062] For a hair removal device with low light uniformity or a small proportion of the light spot on the light emitting surface 72 to the light emitting surface 72, the hair removal device may need to irradiate the same position multiple times to achieve uniform hair removal during use, otherwise the hair removal will be uneven and unsightly. In the solution of the present application, the structure and relative position relationship of the light source 2, the reflective cup 1, and the second light-transmitting body 7 meet the conditions that the light uniformity of the light emitting surface 72 is greater than or equal to 90%, or the light spot on the light emitting surface 72 occupies at least 95% of the light emitting surface 72, so that the hair removal device does not need to irradiate the same position multiple times. If the quality of the light source 2 and the power of the hair removal device are sufficient, and the conditions of human health are met, the hair removal device can achieve efficient and uniform hair removal with a single irradiation.

[0063] Optionally, the centers of the reflective cup 1, the light source 2, and the second light-transmitting body 7 can be on a straight line, and by adjusting the distances between the three on the straight line, the light uniformity of the light-emitting surface 72 can be greater than or equal to 90%, or the light spot on the light-emitting surface 72 can occupy at least 95% of the light-emitting surface 72. Optionally, the hair removal device can also meet the above conditions by adjusting the structures of the three.

[0064] Optionally, the center of the light source 2 is located between the focus of the reflective cup 1 (marked as 1a in the figure) and the bottom of the reflective cup 1, the light incident surface 71 of the second light-transmitting body 7 is located between the light-emitting surface 72 and the focus of the reflective cup 1, and the light reflected by the reflective cup 1 is focused between the light-emitting surface 72 of the second light-transmitting body 7 and the focus of the reflective cup 1. By limiting the positions among the light source 2, the reflective cup 1 and the second light-transmitting body 7, the light uniformity of the light-emitting surface 72 is greater than or equal to 90%, or the light spot on the light-emitting surface 72 occupies at least 95% of the light-emitting surface 72, so that the light emitted by the light source 2 can be fully reflected by the reflective cup 1 on the second light-transmitting body 7, so as to improve the light uniformity of the second light-transmitting body 7.

[0065] Reference Figure 4 The reflective cup 1 has a first reflective area 11 and a second reflective area 12. The first reflective area 11 is an arc-shaped area including the bottom of the reflective cup 1. The second reflective area 12 is a plane area extending outward from both ends of the arc-shaped area, and the plane area is tangent to the arc-shaped area. Optionally, the light source 2 can be a strip light tube, which emits light. The arc-shaped area of ​​the reflective cup 1 can well reflect the light onto the second light-transmitting body 7. At the same time, the plane area of ​​the reflective cup 1 can also reflect the light onto the second light-transmitting body 7. The light is fully reflected by the arc-shaped area and the plane area, so as to improve the light emission rate and the light utilization rate.

[0066] For example, when the hair removal device is working, the light source 2 emits light, and the first reflection area 11 and the second reflection area 12 of the reflective cup 1 fully reflect the light onto the second light-transmitting body 7. The light is incident from the incident surface of the second light-transmitting body 7, and then the light is emitted from the exit surface of the second light-transmitting body 7, so that the light emission uniformity of the light-emitting surface 72 is greater than or equal to 90%, or the light spot on the light-emitting surface 72 occupies at least 95% of the light-emitting surface 72, thereby improving the light emission uniformity of the hair removal device and improving the use effect of the hair removal device.

[0067] Optionally, the angle between the plane area and the reference line is between 5 and 20 degrees, and the reference line is a line connecting the center of the light source 2 and the center of the second light-transmitting body 7. For example, the angle between the plane area and the reference line can be 5 degrees or 8 degrees, and the angle between the plane area and the reference line can also be 15 degrees. By limiting the angle between the plane area and the reference line, so that the light can be fully reflected on the second light-transmitting body 7, on the one hand, the waste of light can be reduced to reduce the cost of use, and on the other hand, the uniformity of light output from the second light-transmitting body 7 can be improved.

[0068] For example, within this range, the focal distance is short, and under the conditions of satisfying light uniformity and light utilization, the second light-transmitting body 7 can be closer to the light source 2, making the structure of the hair removal device more compact and saving materials in processing.

[0069] Reference Figure 1 , Figure 2 and Figure 4 The hair removal device includes side reflectors 13, which are arranged at both ends of the reflector cup 1 in the length direction, and reflect the light leaking from both ends of the reflector cup 1 to the light emitting side of the reflector cup 1. The light emitted by the light source 2 is fully reflected by the side reflectors 13, so as to improve the utilization rate of the light, so that the hair removal device can remove hair efficiently. At the same time, the light source 2 can be easily installed by the side reflectors 13, thereby improving the installation efficiency.

[0070] Optionally, the side reflector 13 is integrally formed with the reflective cup 1 , which can reduce the difficulty of installation in terms of processing. In addition, the side reflector 13 is integrally formed with the reflective cup 1 , which is solid and firm, and can improve the connection stability between the side reflector 13 and the reflective cup 1 , so as to increase the service life of the reflective cup 1 .

[0071] Optionally, the light source 2 is a strip-shaped lamp tube, and the side reflectors 13 on both sides of the reflective cup 1 are provided with through holes 131, and the ends of the lamp tube pass through the through holes 131. Both ends of the lamp tube are connected with fixing members 8, which are used to movably fix the light source 2 on the reflective cup 1. For example, the fixing member 8 can be a silicone soft cover, or a rubber cover. The fixing member 8 is cylindrical, and the fixing member 8 has a receiving groove 81, and both ends of the lamp tube are embedded in the installation. The fixing member 8 has a mounting hole 82 along the axis position, and the mounting hole 82 is connected to the receiving groove 81. Both ends of the lamp tube are extended with mounting columns 21, and the mounting columns 21 pass through the mounting holes 82. The fixing member 8 is arranged on the outside of the reflective cup 1.

[0072] Optionally, both ends of the heat dissipation base 4 are integrally formed with supporting blocks 43, and the supporting blocks 43 have a notch, which can accommodate the two ends of the light source 2 and the fixing member 8. When the heat dissipation base 4 and the bracket 6 are kept in a buckled state, the bracket 6 and the supporting block 43 fix the fixing member 8, and then fix the lamp tube on the reflective cup 1. The fixing member 8 itself is elastic. During the process of fixing the fixing member 8 by the bracket 6 and the supporting block 43, if the fixing member 8 is squeezed, the fixing member 8 can change its own shape accordingly to adapt to the shape of the notch, while minimizing the squeezing of the lamp tube as much as possible, so as to reduce the damage of the lamp tube.

[0073] The present embodiment discloses a depilatory device, which has the function of improving the heat dissipation effect of the depilatory device. The light source 2 is assembled in the reflective cup 1 and can emit light. The reflective cup 1 can reflect the light, thereby realizing the light emission of the depilatory device, so as to remove the hair on the skin and achieve the purpose of depilation. The first light-transmitting body 3 and the reflective cup 1 constitute a cavity for accommodating the light source 2. The main body of the light source 2 is suspended in the cavity. The two sides of the heat dissipation base 4 are thermally coupled with the reflective cup 1 and the refrigeration element 5 respectively, so that the heat in the cavity can be quickly transferred out of the cavity, that is, the heat in the cavity is transferred to the heat dissipation base 4 and the refrigeration element 5, and then the cavity is cooled, which can improve the heat dissipation effect of the depilatory device, and at the same time, the light source 2 can be evenly dissipated, thereby extending the service life of the light source 2. Furthermore, good heat dissipation can improve the comfort of use of the depilatory device.

[0074] See also Figure 6 , Figure 6 It is a schematic diagram of the structure of an embodiment of the present application. The hair removal device includes a head 111 and a gripping portion 112 connected to the head 111. The head 111 is provided with a cold compress portion 1111 for fitting the skin. The cold compress portion 1111 can emit light to irradiate the hair follicles of the user's skin, and use the light to penetrate the skin to irradiate the hair follicles for hair removal. At the same time, the cold compress portion 1111 can quickly cool down to reduce the burning sensation caused by the light to the skin, so that the user will not feel discomfort during use. In some embodiments, the cold compress portion 1111 can also emit some light for skin care, so that the hair removal device has both hair removal and skin care functions.

[0075] Optionally, the gripping portion 112 may include a hollow shell (not numbered in the figure), the surface of the shell is provided with an air hole 1211, the air hole 1211 connects the inside of the shell with the outside, so that the hair removal device can exchange airflow with the outside through the air hole 1211 to reduce the internal temperature. The shell also includes an interface 1212, which can be used to connect an external power source to charge the hair removal device. The position of the interface 1212 in the shell is not limited.

[0076] See also Figure 6 and 7 , Figure 7 is a schematic diagram of an exploded structure of an embodiment of the present application, wherein Figure 7 The arrows shown are the airflow directions in the hair removal device driven by the cold drive assembly, the straight lines represent the cold airflow, and the wavy lines represent the hot airflow. Specifically, the hair removal device may include a housing, a light irradiation cover plate 113 disposed on an opening of the housing, a hair removal mechanism 14 accommodated in the housing, and a bottom cover 15.

[0077] In this embodiment, the shell may include a first shell 121 and a second shell 122. The first shell 121 and the second shell 122 are interlocked and connected to form a cavity with openings at both ends. The hair removal mechanism 14 is accommodated in the cavity. The lighting cover 113 and the bottom cover 15 are respectively covered in the two openings to encapsulate the opening after the first shell 121 and the second shell 122 are connected to form the cavity.

[0078] Optionally, the first shell 121, the second shell 122, the illumination cover plate 113 and the bottom cover 15 may be connected by snap fastening, or by screws or bonding.

[0079] The hair removal mechanism 14 includes a hair removal component 100 , a cold compress component 200 , a heat dissipation base 300 and a cold drive component 400 .

[0080] The cold compress assembly 200 is arranged on a side close to the light cover plate 113. The light cover plate 113 is provided with a through hole (not numbered). Part of the cold compress assembly 200 is exposed to the outside through the through hole of the light cover plate 113 from the inside of the housing to directly contact the skin. It can be understood that part of the cold compress assembly 200 and the light cover plate 113 constitute the head 111 of the hair removal device.

[0081] The hair removal component 100 is arranged on a side of the cold compress component 200 away from the illumination cover plate 113, and is used to emit light to the cold compress component 200. The light can be red light, green light, yellow light or other visible light. After the light enters the cold compress component 200, it passes through the cold compress component 200 into the hair follicles under the skin to achieve hair removal.

[0082] The heat dissipation base 300 is disposed on one side of the cold compress assembly 200 and is connected to the cold compress assembly 200. Since the cold compress assembly 200 can absorb the heat from the skin when it is attached to the skin to reduce the temperature of the skin and alleviate the burning sensation, the temperature of the cold compress assembly 200 will increase when used for a long time, and the cooling effect will decrease. The heat dissipation base 300 can absorb the heat of the cold compress assembly 200, so that the cold compress assembly 200 is kept in a low-temperature working environment, ensuring the cooling effect of the cold compress assembly 200 on the skin. Therefore, the hair removal device in this embodiment can still maintain a low temperature state of the body under continuous use, and will not cause pain to the user.

[0083] The cold drive component 400 is disposed on at least a part of the side of the heat dissipation base 300 facing away from the hair removal component 100 , and is used to dissipate heat for the hair removal component 100 and the heat dissipation base 300 .

[0084] In this embodiment, the cold drive component 400 inhales external cooling medium into the hair removal device through the air vent 1211 , and the cooling medium takes away the heat after passing through the hair removal component 100 and the heat dissipation base 300 and then flows out from the air vent 1211 .

[0085] Optionally, the external cooling medium may be air. After the cold drive component 400 inhales the air, it blows air toward the hair removal component 100 and the heat dissipation base 300, and the heat of the hair removal component 100 and the heat dissipation base 300 is taken away by the airflow.

[0086] In this embodiment, the air holes 1211 are provided on the first housing 121, and at least part of the cold drive assembly 400 is opposite to the air holes 1211, so that the cold drive assembly 400 can better absorb the external cooling medium entering through the air holes 1211, thereby increasing the heat dissipation efficiency. In other embodiments, the air holes 1211 can also be provided on the second housing 122.

[0087] See also Figure 7 and Figure 8 , Figure 8 yes Figure 7 Schematic diagram of the exploded structure of the embodiment, wherein Figure 8 The arrow shown indicates the air outlet direction of the fan.

[0088] In this embodiment, the hair removal device further includes a bracket 500, a circuit board 600, a processor 700 and a capacitor 800, the hair removal component 100 and the cold compress component 200 are installed in the bracket 500, and the cold drive component 400 is arranged adjacent to the bracket 500. The hair removal component 100, the cold compress component 200 and the cold drive component 400 are installed on the circuit board 600 and are electrically connected to the circuit board 600.

[0089] The processor 700 and the capacitor 800 are electrically connected to the circuit board 600 and are arranged on the circuit board 600. When an external power source is connected, the external power source can charge the capacitor 800 so that the capacitor 800 can provide electrical energy for the hair removal device, and the capacitor 800 can store electrical energy when connected to the external power source so that the hair removal device can be used when not connected to the external power source. The processor 700 sends control instructions to the hair removal component 100, the cold compress component 200 and the cold drive component 400 to control the operation of the hair removal device. For example, the switch, thermal protection or power adjustment of the hair removal device are controlled.

[0090] In this embodiment, the circuit board 600 may be fixed in the second housing 122 , and the circuit board 600 may be a PCBA circuit board.

[0091] In the related art, the internal heat of the hair removal device is often continuously increased during use, and the internal circuits and components of the hair removal device are prone to explosion, burnout, short circuit and other dangerous situations in a high temperature environment. In this embodiment, the cold drive component 400 can dissipate heat for the hair removal component 100 and the heat dissipation base 300, and the heat dissipation base 300 can dissipate heat for the cold compress component 200, so that the cold compress component 200 can cool the skin, improve the comfort of the skin, and prevent explosion, burnout, short circuit and other problems caused by excessive temperature.

[0092] Specifically, the hair removal assembly 100 may include a light source 101 , a reflective cup 102 , a filter 103 and two electrodes 104 .

[0093] The light source 101 , the reflective cup 102 and the filter 103 are installed in the bracket 500 , that is, the bracket 500 is provided with mounting positions for the light source 101 , the reflective cup 102 and the filter 103 , and the light source 101 , the reflective cup 102 and the filter 103 are snapped into the mounting positions of the bracket 500 .

[0094] Among them, the light source 101 is arranged opposite to the cold compress component 200, and the light emitted by the light source 101 can be directly injected into the cold compress component 200. The reflective cup 102 is arranged on the side of the light source 101 away from the cold compress component 200, and the light of the light source 101 is reflected and injected into the cold compress component 200 to prevent the loss of light energy. The filter 103 is located between the light source 101 and the cold compress component 200, that is, the light source 101, the filter 103 and the cold compress component 200 are arranged in sequence along the direction of light propagation, and the filter 103 is used to filter some harmful light emitted by the light source 101. Reduce the damage of light to the skin and improve the safety of hair removal. The two electrodes 104 are respectively connected to the two sides of the light source 101, and are electrically connected to the circuit board 600 for transmitting electrical signals.

[0095] Optionally, the light source 101 can be a lamp tube. The color of the light emitted by the lamp tube is not limited, and can be colored light, composite light, etc. The specific wavelength and frequency depend on the usage. The type of lamp tube is also not limited, and can be a semiconductor xenon lamp tube, a quartz lamp tube, a laser lamp tube, etc. The photon type can be IPL (Intense Pulse Light), DPL (Delicate Pulse Light), OPT (Optimal Pulse Technology), AOPT (Advanced Optimal Pulse Technology), BBL (BroadBand Light, BB light), etc. The specific type depends on the preset effect.

[0096] Optionally, the reflective cup 102 can be a U-shaped reflective plate, which is arranged around the light source 101, and the opening of the U-shaped reflective plate faces the cold compress component 200, so as to reflect the light that is not incident on the cold compress component 200 to the cold compress component 200. At the same time, the reflective cup 102 can also prevent the heat generated by the light source 101 from being dissipated to other components in the hair removal device. In this embodiment, the bracket 500 includes a fixing frame 550 and a pipe 560, wherein the fixing frame 550 is provided with a first accommodating space 510 and a second accommodating space 520 inside. The first accommodating space 510 is used to install the hair removal component 100, and the second accommodating space 520 is used to install the cold compress component 200. The first accommodating space 510 and the second accommodating space 520 are arranged adjacent to each other to reduce the distance between the hair removal component 100 and the cold compress component 200, and reduce the optical path loss of the light emitted from the hair removal component 100. The second accommodating space 520 is closer to the first accommodating space 510 than to the first accommodating space 510. Figure 6 The head 111 of the hair removal device is shown.

[0097] When the hair removal device is working, the light source 101 will generate a lot of heat, and the reflective cup 102 and the filter 103 will also be irradiated by light, resulting in temperature rise, so the light source 101, the reflective cup 102 and the filter 103 need to be cooled.

[0098] In this embodiment, the bracket 500 includes a fixing frame 550 and a pipe 560, one end of the pipe 560 is connected to one side of the fixing frame 550, and the other end extends toward the cold drive assembly 400. The fixing frame 550 is provided with an air outlet 540 connected to the first accommodation space 510, and the pipe 560 is provided with an air inlet 530 connected to the first accommodation space 510, and the air inlet 530, the first accommodation space 510 and the air outlet 540 are connected in sequence.

[0099] The air inlet 530 is connected to the cold drive assembly 400, and the air outlet 540 is connected to the air vent 1211. The cold drive assembly 400 inhales external air and enters through the air vent 1211, and blows toward the air outlet 540. After the air enters the first accommodation space 510 from the air outlet 540, it takes away the heat of the light source 101, the reflective cup 102, and the filter 103 in the first accommodation space 510, and flows to the outside from the air outlet 540 and the air vent 1211, dissipating heat energy to the outside.

[0100] Optionally, a portion of the fixing frame 550 and the pipe 560 constitute the first bracket 501, and the remaining portions of the fixing frame and the pipe constitute the second bracket 502. In other embodiments, the fixing frame 550 may also be integrally formed.

[0101] The first bracket 501 and the second bracket 502 can be connected together by snapping. The first bracket 501 is close to the first shell 121, and the second bracket 502 is close to the second shell 122. The air outlet 540 is arranged on the first bracket 501 and is arranged opposite to the air vent 1211 of the first shell 121 to accelerate the heat dissipation efficiency of the air outlet 540. The first accommodating space 510 is arranged in the parts where the first bracket 501 and the second bracket 502 respectively correspond to the parts of the fixing frame 550, and the air inlet 530 is arranged in the parts where the first bracket 501 and the second bracket 502 respectively correspond to the parts of the pipeline 560, which are connected to the first accommodating space 510 and the cold drive assembly 400. The interior of the bracket 6 can be provided with a channel for guiding air, so as to facilitate the airflow of the cold drive assembly 400 to be introduced into the first accommodating space 510.

[0102] Therefore, in this embodiment, the hair removal component 100 dissipates heat through the cold drive component 400, thereby ensuring the safety of the hair removal device.

[0103] Furthermore, in this embodiment, the cold compress assembly 200 may include a second light-transmitting body 201 and a cooling element 202 .

[0104] The second light-transmitting body 201 is used to fit the skin. The second light-transmitting body 201 is arranged opposite to the light source 101. The second light-transmitting body 201 is a light-transmitting element. After the light emitted by the light source 101 enters the second light-transmitting body 201, it is emitted from the second light-transmitting body 201 and enters the skin.

[0105] Optionally, the second light-transmitting body 201 may be a light-conducting crystal, specifically sapphire, K9 glass or crystal glass. When the second light-transmitting body 201 is made of sapphire, the second light-transmitting body 201 has excellent thermal conductivity.

[0106] Optionally, the second light-transmitting body 201 may be a cylinder or a cube, and a surface of the second light-transmitting body 201 away from the light source 101 is used to fit against the skin.

[0107] The cooling element 202 is connected to the second light-transmitting body 201, and is used to absorb the heat of the second light-transmitting body 201. Since the second light-transmitting body 201 rises in temperature after contacting the skin, the cooling element 202 can absorb the heat energy of the second light-transmitting body 201 after the temperature of the second light-transmitting body 201 rises, so that the second light-transmitting body 201 maintains a low temperature, and further, when the second light-transmitting body 201 is used for a long time and is in contact with the skin, the second light-transmitting body 201 can still provide a cold compress to the skin, thereby reducing the pain of the skin.

[0108] Furthermore, the cooling element 202 may be a cooling element of a semiconductor cooling method, and one end of the cooling element 202 that absorbs heat is connected to the second light-transmitting body 201 , and the other end releases heat.

[0109] In order to dissipate heat from the heat-dissipating end of the refrigerating element 202 , in this embodiment, the heat-dissipating base 300 is connected to the heat-dissipating end of the refrigerating element 202 to absorb the heat of the refrigerating element 202 .

[0110] Specifically, the heat dissipation base 300 includes a heat dissipation plate 301 and heat dissipation fins 302. A surface of the heat dissipation plate 301 is provided with a first area 310 and a second area 311 arranged side by side. The hair removal component 100 is arranged in the first area 310, and the heat dissipation fins 302 are installed in the second area 311. The second area 311 is located on the side where the fixing frame 550 is connected to the pipeline 560. The heat dissipation fins 302 and the pipeline 560 are arranged side by side on one side of the fixing frame. The fixing frame 550 is arranged in the first area 310. The heat dissipation plate 301 is installed on the circuit board 600 and connected to the cold compress component 200. Specifically, the refrigeration component 5 can be bonded to the heat dissipation plate 301 through thermal conductive silicone grease. The cold compress component 200 can quickly introduce heat into the heat dissipation plate 301 through thermal conductive silicone grease, and the heat dissipation fins 302 can dissipate heat from the heat dissipation plate 301, and assist the heat dissipation of the heat dissipation plate 301, so that the heat dissipation plate 301 can continuously absorb the heat of the refrigeration component 202.

[0111] Optionally, there are multiple heat dissipation fins 302 , and the multiple heat dissipation fins 302 are parallel to each other. The heat dissipation fins 302 can be mounted on the heat dissipation plate 301 by welding.

[0112] Optionally, the surface of the heat sink fins 302 may be sprayed with thermal conductive paint, which can not only radiate the heat of the heat sink fins 302 but also prevent the heat sink fins 302 from being affected by water vapor and prevent corrosion and wear.

[0113] In this embodiment, the heat sink 301 can be a temperature averaging plate, which can absorb heat when the liquid working medium inside evaporates when heated, and dissipate heat and liquefy when cooled, so that the surface temperature of the temperature averaging plate remains consistent through evaporation and condensation cycles. Therefore, a part of the surface of the heat sink 301 is connected to the refrigeration element 5, and the other part is connected to the heat dissipation fins 302, so that the heat generated by the refrigeration element 202 is dissipated through the heat sink 301 and the heat dissipation fins 302.

[0114] Optionally, see Fig. 9 A carbon-containing layer 92 may be provided between the second light-transmitting body 201 and the heat dissipation base 300, for example, provided on the surface of the heat dissipation plate 301 and the second light-transmitting body 201 on the side where the heat dissipation plate 301 is thermally coupled. The carbon-containing layer 92 has excellent thermal conductivity, can accelerate the thermal conductivity rate of the heat dissipation plate 301, and enhance the heat dissipation performance of the heat dissipation base 300.

[0115] Optionally, the carbon-containing layer is a graphene material, graphite powder, graphite sheet or graphite film.

[0116] Optionally, the carbon-containing layer is provided by plating, spraying or lamination.

[0117] In order to improve the heat dissipation performance of the heat dissipation base 300 , in this embodiment, the heat dissipation base 300 is also connected to the cold drive assembly 400 .

[0118] Specifically, the heat sink fins 302 of the heat sink base 300 are connected to the cold drive assembly 400 . The cold drive assembly 400 inhales external air from the air vents 1211 and drives the air to blow toward the heat sink fins 302 . The air flows through the heat sink fins 302 to dissipate heat from the heat sink fins 302 .

[0119] In an exemplary embodiment, the heat sink fins 302 are arranged in parallel with the airflow provided by the cold drive assembly 400 to increase the contact area between the heat sink fins 302 and the airflow, thereby increasing the heat dissipation efficiency of the heat sink fins 302 .

[0120] The heat dissipation fins 302 are arranged opposite to the air holes 1211 on the first housing 121 , and the airflow quickly flows out from the air holes 1211 after passing through the heat dissipation fins 302 .

[0121] Therefore, the cold drive component 400 in this embodiment can not only drive the cooling medium to dissipate heat from the hair removal component 100, but also dissipate heat from the heat dissipation base 300. With improved safety performance, the irradiated skin can be cooled by cold compress to alleviate the burning pain caused by the irradiated skin, and the cold compress component 200 can be close to zero degrees under the action of the heat dissipation base 300 and the cold drive component 400, so that the skin near the light outlet can reach a temperature infinitely close to the freezing point, which can alleviate the burning pain of the skin, and short-term contact will not cause skin damage.

[0122] Please also read Figure 7 , Figure 8 and Fig.10 , Fig.10 yes Figure 8 Schematic diagram of the structure of the fan housing at the air outlet in the embodiment. In this embodiment, the cold drive assembly 400 may include a fan housing 401 and a fan 402. The fan housing 401 is arranged on the side of the heat dissipation base 300 facing away from the cold compress assembly 200, and the fan 402 is accommodated in the fan housing 401.

[0123] The fan 402 is opposite to the air vent 1211 on the first housing 121 at one end where air enters, and the fan 402 drives external air to enter the fan 402 through the air vent 1211. The fan housing 401 is provided with an air outlet 410 for discharging air, and the fan 402 is connected to the air outlet 410 at one end where air exits, and the fan 402 drives external air to enter the fan 402 through the air vent 1211, and then flows out from the air outlet 410.

[0124] Optionally, the fan 402 may be a centrifugal fan, an axial flow fan, a mixed flow fan or a cross flow fan.

[0125] Furthermore, the air outlet 410 includes a first air outlet 411 and a second air outlet 412 , and the air discharged by the fan 402 at the air outlet 410 is divided into two parts, one part flows out from the first air outlet 411 , and the other part flows out from the second air outlet 412 .

[0126] Optionally, the air outlet 410 may further include a third air outlet or more air outlets, which is not limited here.

[0127] In this embodiment, the first air outlet 411 is connected to the air inlet 530 of the bracket 500, and the fan 402 drives external air to enter the fan 402 through the air vent 1211. The fan 402 drives the airflow from the first air outlet 411 and the air inlet 530 to enter the first accommodating space 510, and takes away the heat of the light source 101, the reflective cup 102 and the filter 103 in the first accommodating space 510, and finally flows to the outside from the air outlet 540 and the air vent 1211, dissipating heat energy to the outside, thereby achieving heat dissipation of the hair removal component 100.

[0128] In this embodiment, the second air outlet 412 is connected to the heat dissipation fins 302 of the heat dissipation base 300, and the fan 402 drives the external air to enter the fan 402 through the air vents 1211. The fan 402 drives the airflow from the second air outlet 412 into the plurality of heat dissipation fins 302 of the heat dissipation base 300. After the airflow passes through the heat dissipation fins 302, it takes away the heat of the heat dissipation fins 302 and flows out from the air vents 1211. After the temperature of the heat dissipation fins 302 drops, the heat of the heat dissipation plate 301 also drops, so that the heat dissipation plate 301 can absorb the heat energy of the cold compress assembly 200, thereby achieving heat dissipation of the cold compress assembly 200.

[0129] Optionally, the air flow rate in the first air outlet 411 and the second air outlet 412 is not limited and is set according to actual conditions. The air flow rate in the first air outlet 411 and the second air outlet 412 can be controlled by setting the size of the first air outlet 411 and the second air outlet 412. For example, in this 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 more air flows out from the second air outlet 412 to enhance the heat dissipation efficiency of the heat dissipation plate 301.

[0130] In summary, the hair removal device of the present embodiment dissipates heat for the hair removal component 100, the cold compress component 200 and the heat dissipation base 300 through the cold drive component 400, thereby achieving simultaneous heat dissipation for the hair removal component 100 and the cold compress component 200, thereby improving the heat dissipation capacity of the hair removal device and enhancing the safety factor of the hair removal device. At the same time, the cold compress skin can be continuously kept at a temperature infinitely close to the freezing point, thereby reducing the burning sensation of the skin and causing no skin damage during hair removal.
