Description

Technical Field

[0001] The present invention relates to the technical field of hair removal devices, and particularly to a hair removal device.

Background Art

[0002] In order to remove body hair, people use various methods for hair removal. Generally, the more common one is light hair removal, that is, by irradiating the skin with intense pulsed light, the pigment in the skin hair follicles absorbs the light energy and generates heat, the hair follicles necrosis and the hair falls off, and the hair will no longer grow, so as to achieve the purpose of long-term hair removal.

[0003] Generally, a hair removal device uses an intense pulsed light source as the hair removal light source. The intense pulsed light source is a lamp tube sealed with an inert gas (such as xenon), and a coil is wound around the lamp tube. When working, first charge the capacitor, then the capacitor discharges, apply a voltage to the positive and negative electrodes of the lamp tube, and then apply a voltage to the coil to ionize the inert gas in the lamp tube to conduct electricity. Finally, the positive and negative electrodes of the lamp tube are conducted to make the lamp tube emit light. When the lamp tube conducts and emits light, the electrodes of the lamp tube will simultaneously emit a large amount of heat, causing the temperature of the contact part at the light outlet of the hair removal device to rise sharply. When the contact part contacts the skin, the skin gets hot, and the hair removal experience is poor.

[0004] To solve the above problems, existing hair removal devices generally set a heat dissipation component and a fan in the housing. First, the heat dissipation component conducts and takes away the heat of the contact part to reduce its temperature, and then the fan blows towards the heat dissipation component to take away its heat. Existing fans generally include a fixed frame, a stator and a rotor connected in a rotating manner, and a connecting frame. The stator is connected to the fixed frame through the connecting frame, and then the fixed frame is locked in the hair removal device by screws. However, the fixed frame has a large volume, and a large space needs to be reserved in the hair removal device housing to install the fan, resulting in a bloated volume of the hair removal device and inconvenient to hold.

[0046] The hair removal device 100 of the present application includes a hair removal mechanism 20 and a cold compress mechanism 10. The hair removal mechanism 20 and the cold compress mechanism 10 exist as two independent modules and are electrically connected to each other. The hair removal mechanism 20 and the cold compress mechanism 10 can be detachably electrically connected or fixedly connected. The hair removal mechanism 20 is used to irradiate the skin with intense pulsed light. The pigment in the hair follicles of the skin absorbs the light energy and generates heat, causing the hair follicles to necrosis and the hair to fall off, and the hair will no longer grow, thereby achieving the purpose of long-term hair removal. The cold compress mechanism 10 covers the light outlet 218 of the hair removal mechanism 20. The hair removal mechanism 20 indirectly contacts the skin through the cold compress mechanism 10. The cold compress mechanism 10 has a refrigeration effect, thereby avoiding the burning sensation caused by the hair removal mechanism 20 to the skin.

[0047] In order to enable those skilled in the art to have a further understanding of the present application, the cold compress mechanism 10 will be introduced in detail below.

[0048] The cold compress mechanism 10 includes: a cold compress shell assembly 11, a cold compress module 12, and a heat pipe 13.

[0049] The cold compress shell assembly 11 is provided with a cold compress hole 117, a first heat dissipation hole 115, and a second heat dissipation hole 118, and the hair removal mechanism 20 is provided with a first air outlet 212, a second air outlet 214, and a heat dissipation channel 216. The cold compress shell assembly 11 is connected to the hair removal mechanism 20. After the cold compress shell assembly 11 and the hair removal mechanism 20 are assembled, the cold compress shell assembly 11 and the hair removal mechanism 20 are separated by a first air flow channel 116 at the cold compress module 12, and a second air flow channel 119 is formed inside the cold compress shell assembly 11. The first air outlet 212, the first heat dissipation hole 115, the first air flow channel 116, and the second heat dissipation hole 118 are connected in sequence, the first air outlet 212, the first heat dissipation hole 115, the second air flow channel 119, and the second heat dissipation hole 118 are connected in sequence, and the second air outlet 214 is connected to the second heat dissipation hole 118. The first air flow channel 116, the second air flow channel 119, and the heat dissipation channel 216 are arranged at intervals.

[0050] The cold compress module 12 is assembled in the cold compress hole 117 and connected to the cold compress shell assembly 11, and the light emitted by the hair removal mechanism 20 is emitted from the cold compress module 12. The cold compress module 12 is used to contact the skin, and the cold compress module 12 has a refrigeration effect, thereby achieving a cooling effect.

[0051] The heat pipe 13 is accommodated in the cold compress shell assembly 11, one end of the heat pipe 13 is connected to the cold compress module 12, and the other end extends to the second air flow channel 119 between the first heat dissipation hole 115 and the second heat dissipation hole 118. The heat pipe 13 transfers the heat of the cold compress module 12 to the first heat dissipation hole 115 and the second heat dissipation hole 118 and discharges it through the second heat dissipation hole 118. The heat pipe 13 makes full use of the heat conduction principle and the rapid heat transfer property of the phase change medium, and quickly transfers the heat in the cold compress module 12 to the far end of the heat source through the heat pipe 13. Its thermal conductivity exceeds the thermal conductivity of any known metal. Further, the cold compress mechanism 10 also includes a plurality of fins 16, and the plurality of fins 16 are sleeved on the heat pipe 13 corresponding to the second heat dissipation hole 118 to increase the contact area between the heat pipe 13 and the air and improve the heat dissipation efficiency. The fins 16 are U-shaped, and the plurality of fins 16 are sleeved on the heat pipe 13 and abut against each other to form a support for each other.

[0052] Part of the heat in the hair removal mechanism 20 is discharged through the second air outlet 214 and the second heat dissipation hole 118 in sequence; another part of the heat in the hair removal mechanism 20 is discharged through the first air outlet 212, the first air flow channel 116, and the second heat dissipation hole 118 in sequence, and the water vapor in the cold compress shell assembly 11 is taken out; another part of the heat in the hair removal mechanism 20 is discharged through the first air outlet 212, the second air flow channel 119, and the second heat dissipation hole 118 in sequence, and the heat near the heat pipe 13 is taken out.

[0053] The cold compress shell assembly 11 includes a first cold compress inner shell 112, a second cold compress outer shell 114, and an end cap 113. The second cold compress outer shell 114 and the first cold compress inner shell 112 are inserted into each other, and the end cap 113 is connected to the second cold compress outer shell 114 and abuts against the first cold compress inner shell 112, thereby completing the fixation of the three. The hair removal mechanism 20 is inserted into the first cold compress inner shell 112, thereby achieving the purpose of being detachable. At this time, it can be an interference fit. Of course, the hair removal mechanism 20 and the cold compress mechanism 10 can also achieve the purpose of being detachable through magnetic attraction.

[0054] The first heat dissipation hole 115 is opened on the first cold compress inner shell 112, the second heat dissipation hole 118 is opened on the end cap 113, the cold compress hole 117 penetrates through the first cold compress inner shell 112 and the second cold compress outer shell 114, and a second air flow channel 119 is formed between the first cold compress inner shell 112 and the second cold compress outer shell 114.

[0055] The material of the first cold compress inner shell 112 can be made of heat-insulating materials such as nylon to prevent the heat in the hair removal mechanism 20 from being transmitted through the first cold compress inner shell 112 to the cold compress mechanism 10, thereby reducing the refrigeration effect of the cold compress module 12.

[0056] In this embodiment, the cold compress module 12 includes a sapphire 121, a conduction member 122, and a refrigeration sheet 123. Among them, the conduction member 122 is used to install the sapphire 121 in the cold compress hole 117 surrounded by the first cold compress shell 112 and the second cold compress shell 114, and is used to contact the refrigeration sheet 123 to conduct the heat of the sapphire 121 and itself, and finally keep the sapphire 121 and the conduction member 122 at a low temperature.

[0057] Specifically, the conduction member 122 includes a socket part 1221, a cold compress part 1222 provided at one end of the socket part 1221, a socket hole 1223 formed by enclosing the socket part 1221, and a fixing column 1224 provided on the cold compress part 1222. The cold compress part 1222 extends partially into the socket hole 1223 to form a pressing part 1225. The sapphire 121 is received in the socket hole 1223. One side of the sapphire 121 abuts against the second cold compress shell 114, and the other side abuts against the pressing part 1225 of the cold compress part 1222. The first cold compress shell 112 is provided with a through hole 1121. The fixing column 1224 of the conduction member 122 passes through the through hole 1121 and is locked to the second cold compress shell 114 by screws. The cold compress part 1222 abuts against the first cold compress shell 112, and the pressing part 1225 presses the sapphire 121 against the second cold compress shell 114, so that the sapphire 121 is clamped and fixed between the cold compress part 1222 and the second cold compress shell 114, thereby completing the fixation of the sapphire 121.

[0058] To increase the stability of the fixation of the sapphire 121, steps are provided at both ends of the sapphire 121 that are in contact with the pressing portion 1225 and the second cold compress shell 144. The pressing portion 1225 and the second cold compress shell 144 are respectively snap-fitted with the steps at both ends of the sapphire 121 and are pressed against each other.

[0059] The thermoelectric cooler 123 is attached to the side of the socket portion 1221 away from the sapphire 121. It absorbs the heat of the sapphire 121 and the cold compress portion 1222 through the socket portion 1221, thereby maintaining the sapphire 121 and the cold compress portion 1222 at a low temperature. When the cold compress portion 1222 and the sapphire 121 come into contact with the human skin, they perform cold compress on the human skin to reduce the temperature of the human skin. The material of the conduction member 122 can be made of a metal material with high thermal conductivity such as aluminum or copper.

[0060] In other embodiments, the cold compress module 12 may also include only the sapphire 121 and the thermoelectric cooler 123. The sapphire 121 is received in the cold compress hole 117 and is clamped and fixed by the first cold compress shell 112 and the second cold compress shell 114, while the thermoelectric cooler 123 is directly attached to the side of the sapphire 121, enabling the sapphire 121 to cool down more quickly and maintain a lower temperature, thus having a better cold compress effect.

[0061] The sapphire 121 can not only transmit light but also has excellent thermal conductivity, ensuring high thermal conductivity between the thermoelectric cooler 123 and the sapphire 121, thereby enabling the sapphire 121 to have a stable low temperature. Of course, the sapphire 121 can also be replaced with a light-transmitting object such as ordinary glass.

[0062] Further, please refer to Figure 7 , two thermoelectric coolers 123 are attached to both sides of the socket portion 1221. One side of the heat pipe 13 is fixed to the fixing seat 18, and the other side of the heat pipe 13 is attached to the side of the thermoelectric cooler 123 away from the socket portion 1221. Among them, the thermoelectric cooler 123 is a semiconductor thermoelectric cooler, and its cooling surface is in contact with the socket portion 1221 to absorb the heat of the socket portion 1221 and the sapphire 121, thereby reducing the temperature of the socket portion 1221 and the sapphire 121; while the heat dissipation surface of the thermoelectric cooler 124 is in contact with the heat pipe 13, and the heat of the heat dissipation surface of the thermoelectric cooler 124 is absorbed through the phase change of the medium in the heat pipe 13, thus ensuring the normal operation of the thermoelectric cooler 124.

[0063] In other embodiments, the socket portion 141 may be provided with a notch, and the sapphire 121 is installed in the notch and is in direct contact with the thermoelectric cooler 123.

[0064] The cold compress mechanism 10 further includes a fixing shell 15, which includes a fixing wall 151, a plugging part 152 provided at one end of the fixing wall 151, and a fixing frame 153 provided inside the fixing wall 151. The second cold compress outer shell 114 is provided with a slot 1141, and the fixing shell 15 is fixed to the first cold compress inner shell 112 through the plugging of the plugging part 152 and the slot 1141.

[0065] When the hair remover 100 removes hair, it will cause damage to the hair follicles. If not treated, it will cause hair follicle inflammation and affect the health of users. To solve the above problems, the hair remover 100 is further provided with a plurality of sterilization and disinfection modules 30. The plurality of sterilization and disinfection modules 30 are fixed on the first cold compress inner shell 112. Each sterilization and disinfection module 30 includes a lamp board 32 and a sterilization lamp 34 provided on the lamp board 32. The lamp board 32 is fixed to the first cold compress inner shell 112, and the sterilization lamp 34 faces the edge of one end of the sapphire 121. Optionally, the sterilization lamp 34 is an LED lamp that can emit blue light.

[0066] When the user uses the hair remover 100 to remove hair, the sterilization and disinfection module 30 is turned on. The light emitted by the sterilization lamp 34 is transmitted through the sapphire 121 and then irradiates the human skin to sterilize and disinfect the hair follicles of the skin, thereby avoiding hair follicle inflammation of the user's skin.

[0067] To enable those skilled in the art to have a further understanding of this application, the hair removal mechanism 20 will be introduced in detail below.

[0068] The hair removal mechanism 20 includes a hair removal shell assembly 21, a filter 22, a light emitting assembly 23, and a fan 24.

[0069] The hair removal shell assembly 21 includes a middle shell 211 in a cylindrical shape with openings at both ends, a lower shell 213 and an upper shell 215 connected to both ends of the middle shell 211. An air inlet channel 2111 is formed on the inner wall of the middle shell 211, and a plurality of chutes 2112 for fixing the fan 24 are provided. The lower shell 213 is provided with a plurality of air inlet holes 2131 communicating with the air inlet channel 2111. The upper shell 215 is provided with a light outlet hole 218, a first air outlet hole 212, and a second air outlet hole 214. The light outlet hole 218 is opposite to the cold compress hole 117. A first air flow channel 116 is formed between the hair removal shell assembly 21 and the cold compress shell assembly 11 at the light outlet hole 218 and the cold compress hole 117. The hair removal shell assembly 21 forms a heat dissipation channel 216 spaced from the first air flow channel 116 and the second air flow channel 119 respectively. The heat dissipation channel 216 communicates with the air inlet channel 2111. The cold compress shell assembly 11 and the hair removal shell assembly 21 can be detachably connected, and the two can be detachably connected by interference fit. The hair removal shell assembly 21 can be in a straight cylindrical shape to shorten the length of the heat dissipation channel 216, reduce the path of air flowing to the second heat dissipation hole 118, and enable heat to be quickly discharged following the air. Optionally, the light emitting assembly 23 is a high-intensity pulsed light source.

[0070] The filter 22 is assembled in the light outlet hole 218 and connected to the hair removal housing assembly 21. Since the light-emitting component 23 is a high-intensity pulsed light source, the light it emits includes ultraviolet light and visible light. Ultraviolet light is likely to cause damage to the human skin. Therefore, it is necessary to use the filter 22 to filter the ultraviolet light generated by the light-emitting component 23. In addition, the light-emitting component 23 generates a large amount of heat during hair removal. The filter 22 rapidly heats up due to absorbing the heat generated by the light-emitting component 23. By arranging the filter 22 and the cold compress module 12 at intervals to form the first air flow channel 116, the heat insulation ability of the filter 22 and the cold compress module 12 is greatly improved, preventing heat from being conducted from the high-temperature filter 22 to the cold compress module 12 and enabling the cold compress module 12 to maintain a low temperature. When the cold compress module 12 contacts the human skin, the low-temperature cold compress module 12 effectively reduces the skin temperature and simultaneously dulls the skin sensitivity, improving the user experience. In addition, a first air flow channel 116 is formed between the filter 22 and the cold compress module 12. During the air flow in the first air flow channel 116, water vapor will be carried away, preventing the filter 22 from bursting due to water vapor.

[0071] The light-emitting component 23 is assembled in the hair removal housing assembly 21, and the light emitted by the light-emitting component 23 sequentially exits from the filter 22 and the cold compress module 12.

[0072] The fan 24 is assembled in the hair removal housing assembly 21. The fan 24 is used to blow air towards the first air outlet 212 and the second air outlet 214. The fan 24 is used to accelerate the air flow and make the air move in a certain flow direction. As Figure 3 shown by the arrow, under the action of the fan 24, part of the heat in the hair removal mechanism 20 is sequentially discharged through the second air outlet 214 and the second heat dissipation hole 118; another part of the heat in the hair removal mechanism 20 is sequentially discharged through the first air outlet 212, the first air flow channel 116, and the second heat dissipation hole 118, and the water vapor in the cold compress housing assembly 11 is taken out by the way; another part of the heat in the hair removal mechanism 20 is sequentially discharged through the first air outlet 212, the second air flow channel 119, and the second heat dissipation hole 118, and the heat near the heat pipe 13 is taken out by the way. The fan 24 can be an axial flow fan, or the fan 24 can also be a blower.

[0073] The light-emitting component 23 includes a lamp tube 232 and a reflector 234 assembled in the hair removal housing assembly 21. The reflector 234 covers the lamp tube 232. The length direction of the lamp tube 232 is consistent with the air outlet direction of the fan 24. Or it can be understood that the connection direction between the second air outlet 214 and the second heat dissipation hole 118 is consistent with the length direction of the lamp tube 232. The lamp tube 232 is placed along the air flow direction in the hair removal housing assembly 21 to reduce the obstruction of the lamp tube 232 to the air flow and improve the air flow rate in the hair removal housing assembly 21.

[0074] The cold compress mechanism 10 further includes a plug 17 connected to the cold compress housing assembly 11, and the hair removal mechanism 20 further includes an interface 26 connected to the hair removal housing assembly 21.

Optionally, the interface 26 is a MicroUSB interface, a USB Type-C interface or a contact, and the plug 17 is a MicroUSB plug, a USB Type-C plug or a probe adapted to the interface 26.

It should be noted that the plug 17 and the interface 26 are provided for electrical conduction, and it is also within the scope of protection of the present application to use pins and sockets to achieve electrical conduction.

[0076] Please refer to Figure 4 and Figure 9 , Figure 9 is a schematic structural view of the heat dissipation bracket 25 of the first embodiment of the hair removal mechanism provided by the present application.

[0077] The hair removal mechanism 20 further includes a heat dissipation bracket 25 connected to the light emitting component 23. The heat dissipation bracket 25 fixes the light emitting component 23 and dissipates heat from the light emitting component 23.

[0078] Specifically, the heat dissipation bracket 25 includes a fixing portion 251, a main body portion 253 and a heat dissipation portion 255. The main body portions 253 are provided on opposite sides of the fixing portion 251, and the heat dissipation portion 255 is connected to the main body portion 253. The heat dissipation portion 255 is used to increase the contact area with the air, and the extending direction of the heat dissipation portion 255 is the same as the air outlet direction of the fan 24, so as to reduce the blocking effect of the heat dissipation portion 255 on the air flow. The fixing portion 251 is provided with a fixing groove 252, and the lamp tube 232 of the light emitting component 23 is connected to the fixing groove 252, and the main body portion 253 is connected to the hair removal housing assembly 21. The number of the main body portions 253 can be one, two, three, etc. It can be understood that the number of the lamp tubes 232 is the same as the number of the main body portions 253. The connection manner between the lamp tube 232 and the fixing groove 252 can be snap connection.

[0079] Furthermore, the light emitting component 23 further includes a circuit board 236, and the heat dissipation bracket 25 further includes pins 257. The pins 257 are connected to the ends of the main body portion 253, and the pins 257 are inserted into the circuit board 236 to be electrically connected to the circuit board 236, so that the lamp tube 232 is electrically connected to the circuit board 236 through the heat dissipation bracket 25.

[0080] The material of the heat dissipation bracket 25 can be a highly heat-conductive material such as copper, steel, aluminum, etc., so as to export the heat of the lamp tube 232 through the heat dissipation bracket 25.

[0081] Please refer to Figure 3 、 Figure 10 and Figure 11 , Figure 10 which is a schematic structural diagram of an embodiment of the fan 24 of the first embodiment of the hair removal mechanism provided by the present application. Figure 11 which is a schematic structural diagram of another embodiment of the fan 24 of the first embodiment of the hair removal mechanism provided by the present application.

[0082] In one embodiment, as shown in Figure 10 and Figure 12 , the fan 24 includes: a stator 242, a rotor 244, a bracket 246 and a fixed shell 248. The rotor 244 is rotatably connected to the stator 242, and the stator 242 drives the rotor 244 to rotate. The rotation of the rotor 244 accelerates the air flow. The bracket 246 is connected to the stator 242, and the fixed shell 248 is connected to the bracket 246. The fixed shell 248 is directly connected to the middle shell 211 of the hair removal shell assembly 21. The connection method can be a sliding fit and an interference fit with each other. At this time, the sliding groove 2112 and the protrusion 249 are respectively arranged on the middle shell 211 and the fixed shell 248, so that the fixation of the two can be realized without a locking structure, reducing the fixing parts of the fan 24, reducing the internal space occupied by the fan 24 in the hair removal mechanism 20, facilitating the miniaturization of the hair removal mechanism 20, and being convenient to hold.

[0083] In another embodiment, as shown in Figure 11 and Figure 12 , the fan 24 includes: a stator 242, a rotor 244 and a bracket 246. The rotor 244 is rotatably connected to the stator 242, and the bracket 246 is connected to the stator 242. The bracket 246 is directly slidably mated with the hair removal shell assembly 21. At this time, the sliding groove 2112 and the protrusion 249 are respectively arranged on the middle shell 211 and the bracket 246. Of course, the bracket 246 can also be used as the protrusion 249 to directly slidably mate with the sliding groove 2112 on the middle shell 211. The difference between this embodiment and the previous embodiment is that this embodiment reduces the fixed shell 248, thereby further reducing the space occupied by the fan 24.

[0084] In one embodiment, the fan 24 includes a stator 242 and a rotor 244 rotatably connected to the stator 242. The stator 242 is slidably mated with the middle shell 211. At this time, the stator 242 is provided with a sliding groove 2112, and the hair removal shell assembly 21 is provided with a protrusion 249. The stator 242 and the hair removal shell assembly 21 are slidably mated through the cooperation of the sliding groove 2112 and the protrusion 249. The difference between this embodiment and the previous embodiment is that this embodiment reduces the bracket 246, thereby further reducing the space occupied by the fan 24.

[0085] Further, there are multiple brackets 246, which are arranged at intervals on the outer peripheral wall of the stator 242. The brackets 246 are spiral-shaped to achieve the effect of boosting pressure.

[0086] Further, there are multiple brackets 246, which are arranged at intervals on the outer peripheral wall of the stator 242. The brackets 246 are straight plate-shaped and are arranged along the direction of air flow to reduce wind resistance and improve the air flow efficiency.

[0087] Figure 13 and 14 This is the second embodiment of the hair remover 100'. The difference between the second embodiment and the first embodiment lies in the setting of the air flow channel and the fixing method of the fan 24'. Therefore, only the above differences will be described.

[0088] In this embodiment, the hair remover 100' includes a detachable hair removal mechanism 20' and a cold compress mechanism 10'. The cold compress mechanism 10' includes: a cold compress shell assembly 11', a cold compress module 12', a heat pipe 13' connected to the cold compress module 12', and a plurality of heat sinks 16' fixed to one end of the heat pipe 13' away from the cold compress mechanism 10'. The cold compress shell assembly 11' is provided with a cold compress hole 117', a first heat dissipation hole 115', and a second heat dissipation hole 118' and has a heat dissipation space 18'. The heat dissipation space 18' is provided with a third air inlet hole 181'. The cold compress module 12' is installed in the cold compress hole 117'. The first heat dissipation hole 115' and the second heat dissipation hole 118' are oppositely arranged and communicated with the heat dissipation space 18'. One end of the heat pipe 13' away from the cold compress mechanism 10' and the heat sinks 16' are received in the heat dissipation space 18' and are located between the first heat dissipation hole 115' and the second heat dissipation hole 118'.

[0089] The cold compress shell assembly 11' is detachably connected to the hair removal mechanism 20'. After the cold compress shell assembly 11' and the hair removal mechanism 20' are assembled, a first air flow channel 116' is formed at an interval between the cold compress shell assembly 11' and the hair removal mechanism 20'. The two ends of the first air flow channel 116' are respectively communicated with the first air outlet hole 212' and the third air inlet hole 181'.

[0090] The hair removal mechanism 20' includes a hair removal shell assembly 21', a filter 22', a light emitting component 23', a fan 24', and a lamp holder 25'. The light emitting component 23' is fixed in the hair removal shell assembly 21' through the lamp holder 25'. The hair removal shell assembly 21' is provided with a light emitting hole 218', a first air outlet hole 212', and a second air outlet hole 214'. The light emitting hole 218' and the cold compress hole 117' are opposite. The hair removal shell assembly 21' forms a heat dissipation channel 216'. The second air outlet hole 214' is communicated with the first heat dissipation hole 115'. Specifically, the filter 22' is assembled in the light emitting hole 218' and connected to the hair removal shell assembly 21'. A first air flow channel 116' isolated from the heat dissipation channel 216' is formed between the filter 22' and the cold compress module 12'.

[0091] The fan 24' is installed in the dehairing housing assembly 21', and the fan 24' is used to send air toward the first air outlet 212' and the second air outlet 214'. The fan 24' is used to accelerate the flow of air and make the air move in a certain direction. Figure 14 In the direction indicated by the arrow, under the action of the fan 24', a part of the heat in the depilatory shell component 21' passes through the heat dissipation channel 216', the second air outlet 214', the first heat dissipation hole 11', the heat dissipation space 18' and the second heat dissipation hole 118' in sequence and is discharged from the depilatory device 100'. Another part of the heat in the depilatory shell component 21' passes through the first air outlet 212', the first air flow channel 116', the third air outlet 181', the heat dissipation space 18' and the second heat dissipation hole 118' in sequence and is discharged from the depilatory device 100', and the water vapor in the cold compress shell component 11' is taken out at the same time. The first air flow channel 116' and the heat dissipation channel 216' are independent of each other and do not affect each other.

[0092] The fan 24' includes a stator 242' and a rotor 244' that are rotatably matched, and a retaining wall 243' that surrounds the stator 242' and the rotor 244'. The retaining wall 243' has an air outlet 2431' that is connected to the first airflow channel 116' and the heat dissipation channel 118'. The stator 242' and the retaining wall 243' are directly fixed on the depilatory shell assembly 21', and the depilatory shell assembly 21' is provided with an air inlet 219'. When the rotor 244' is working, the stator 244' pushes the air flow in the retaining wall 243', and generates an airflow at the air outlet 2431' that blows toward the first airflow channel 116' and the heat dissipation channel 216', thereby carrying the heat in the first airflow channel 116' and the heat dissipation channel 216', so as to reduce the temperature of the filter 22' and the cold compress module 12', and the light emitting assembly 23' and the lamp holder 25' respectively. Since the stator 242' and the retaining wall 243' are directly fixed to the depilatory housing assembly 21', the housing for fixing the fan 24' is omitted, the volume of the fan 24' is reduced, and the volume of the depilatory device 100' can be further reduced, so that it is convenient for users (especially female users) to hold.

[0093] In summary, the above-mentioned cold compress mechanism 10 is internally provided with a cold compress module 12 and a heat pipe 13. The heat pipe 13 only cools the cold compress module 12, and the temperature of the cold compress module 12 drops significantly, resulting in a good cold compress effect. The cold compress mechanism 10 is detachably connected to the hair removal mechanism 20, and the hair removal mechanism 20 with different light outlets can be replaced according to the hair removal area. A first air flow channel 116 is formed between the cold compress mechanism 10 and the hair removal mechanism 20, and the water vapor between the cold compress module 12 and the filter 22 is taken away by the fan 24 to prevent the high-temperature filter 22 from cracking due to contact with water droplets. A second air flow channel 119 is formed in the cold compress mechanism 10, and the heat pipe 13 is accommodated in the second air flow channel 119, and the heat of the heat pipe 13 is taken away by the fan 24. Due to the existence of the first air flow channel 116, there is air between the cold compress module 12 and the filter 22. Since the air has a high thermal resistance and poor thermal conductivity, the thermal conductivity between the cold compress module 12 and the filter 22 is poor, preventing the cold compress module 12 from heating up quickly. No heat dissipation structure is provided inside the hair removal mechanism 20, saving a large amount of space. The heat dissipation effect of the lamp tube 232 and the lamp holder is good, which is beneficial to the heat dissipation of the lamp tube 232 by the fan 24. The heat dissipation bracket 25 is made of a heat-conducting material, so that the heat dissipation bracket 25 can be used as a heat dissipation device for the lamp tube 232, and the heat dissipation bracket 25 is also provided with a heat dissipation part 255, further increasing the heat dissipation effect of the heat dissipation bracket 25. The lamp tube 232 and the heat dissipation bracket 25 are vertically arranged in the housing, that is, the lamp tube 232 and the heat dissipation bracket 25 are arranged along the direction of air flow. In this way, the lamp tube 232 and the heat dissipation bracket 25 have a small resistance to the air flow, accelerating the air flow and improving the heat dissipation effect.

[0094] The above are only the embodiments of the present invention. It should be noted here that for those of ordinary skill in the art, without departing from the inventive concept of the present invention, improvements can still be made, but these all fall within the protection scope of the present invention.
