[0020] See also Figure 1 and Figure 2 The present application provides a hair removal device 100 with dual cooling channels, and the hair removal device 100 with dual cooling channels includes:

[0021] The cooling drive unit 10 is provided with a first drive port 11, and the first drive port 11 is used to input or output the cooling medium;

[0022] A cooling bracket 20, fixedly connected to the cooling drive unit 10, and provided with a first cooling channel 21 and a second cooling channel 22 docking with the first drive port 11, wherein the first cooling channel 21 is separated from the second cooling channel 22;

[0023] The hair removal device 30 is fixed in the first cooling channel 21 to remove heat by using the cooling medium in the first cooling channel 21;

[0024] A cold compress part 40, fixed to the cooling bracket 20 and opposite to the hair removal device 30, to receive the light emitted by the hair removal device 30 and emit the light;

[0025] The heat conducting part 50 is fixed to the cooling bracket 20, with a portion in contact with the cold compress part 40 and another portion disposed in the second cooling channel 22 to absorb the heat of the cold compress part 40 and guide it into the second cooling channel 22, and use the cooling medium in the second cooling channel 22 to take away the heat.

[0026] The cooling bracket 20 is provided with a first cooling channel 21 and a second cooling channel 22, and the first cooling channel 21 and the second cooling channel 22 are both connected to the first driving port 11 of the cooling driving part 10, and the hair removal device 30 is fixed in the first cooling channel 21, and a part of the heat conduction part 50 is in contact with the cold compress part 40, and the other part is arranged in the second cooling channel 22, so that the heat dissipation of the heat conduction part 50 and the heat dissipation of the hair removal device 30 are separated, thereby effectively improving the overall cooling efficiency inside the hair removal device.

[0027] It is understandable that the dual cooling channel hair removal device 100 contacts the user's skin with the cold compress part 40, and the cold compress part 40 emits light, which penetrates the skin and irradiates the hair follicles for hair removal. The cold compress part 40 can quickly cool down to reduce the burning sensation caused by the light and ensure comfort.

[0028] In this embodiment, the cooling drive unit 10 drives the external cooling medium to flow into the hair removal device 100 with dual cooling channels, so that the external cooling medium flows into the first cooling channel 21 and the second cooling channel 22, so that the external cooling medium can simultaneously take away the heat of the hair removal device 30 and the heat conduction unit 50. Specifically, the outer side of the first driving port 11 is engaged with the cooling bracket 20 to achieve a sealed connection between the first driving port 11 and the first cooling channel 21 and the second cooling channel 22, thereby reducing the resistance of the external cooling medium entering the first cooling channel 21 and the second cooling channel 22.

[0029] The cooling drive unit 10 drives the external cooling medium to flow through the power device, so that the external cooling medium can effectively take away the heat in the hair removal device 100 with dual cooling channels. The first driving port 11 is connected with the first cooling channel 21 and the second cooling channel 22, so that the cooling drive unit 10 uses a power device to drive the external cooling medium to cool down the hair removal device 30 and the heat conduction unit 50 through the two cooling channels, optimize the internal structure of the hair removal device 100 with dual cooling channels, and increase the internal heat dissipation efficiency of the hair removal device 100 with dual cooling channels.

[0030] Optionally, the cooling drive unit 10 is a fan. The external cooling medium is air. For example, the cooling drive unit 10 is a centrifugal fan, an axial flow fan, a mixed flow fan, and a cross flow fan. Preferably, the cooling drive unit 10 is a centrifugal fan, so that the external air enters the impeller of the fan axially and flows mainly in the radial direction.

[0031] Specifically, the cooling drive unit 10 includes a shell 12 and a fan blade fixed in the shell 12. The first drive port 11 is opened in the shell 12. The shell 12 is firmly connected with the cooling bracket 20 by snap-fitting, and the shell 12 is located on one side of the cooling bracket 20. The first drive port 11 is opened on the peripheral side of the shell 12. The first drive port 11 can be a cooling medium outlet, that is, the cooling drive unit 10 blows cooling medium to the first cooling channel 21 and the second cooling channel 22. Of course, the first drive port 11 can also be a cooling medium suction port, that is, the first drive port 11 sucks cooling medium from the first cooling channel 21 and the second cooling channel 22, so that the cooling medium in the first cooling channel 21 and the second cooling channel 22 flows.

[0032] In this embodiment, the cooling bracket 20 is provided with a bracket head 23, and the cold compress part 40 is fixed to the bracket head 23 so that the cold compress part 40 contacts the user's skin. The cooling bracket 20 is docked with the first driving port 11 at the opposite or adjacent side of the bracket head 23. The first cooling channel 21 and the second cooling channel 22 are docked with the first driving port 11 side by side, and the first cooling channel 21 and the second cooling channel 22 are separated by a partition.

[0033] In this embodiment, the hair removal device 30 emits light toward the cold compress part 40. The heat of the hair removal device 30 can be taken away by the external cooling medium of the first cooling channel 21, and the external cooling medium of the first cooling channel 21 is directly obtained by sucking the cooling medium with reduced external temperature from the cooling drive part 10, so as to effectively reduce the temperature of the hair removal device 30.

[0034] In this embodiment, the cold compress part 40 is fixed to the bracket head 23 of the cooling bracket 20, and the cold compress part 40 partially exposes the bracket head 23 so that the cold compress part 40 can contact the user's skin. The cold compress part 40 is used to contact the user's skin and emit light. The cold compress part 40 has a cold compress surface 41, and the cold compress surface 41 is parallel to the outer end surface of the bracket head 23. The cold compress part 40 also has a heat-conducting surface 42 that exposes the bracket head 23 and is arranged on the side of the cold compress part 40. The heat-conducting surface 42 is in contact with a part of the heat-conducting part 50 so that the heat of the cold compress part 40 is transferred from the heat-conducting surface 42 to the heat-conducting part 50, so that the cold compress part 40 achieves a cooling effect and the cooling rate is accelerated.

[0035] Optionally, the cold compress surface 41 is a flat surface, and the heat conducting surface 42 is a flat surface.

[0036] Optionally, the cold compress surface 41 is an end surface of the cold compress portion 40 . The heat conducting surface 42 is a side surface of the cold compress portion 40 .

[0037] In this embodiment, a portion of the heat-conducting portion 50 is fixed to the bracket head 23 and contacts the heat-conducting surface 42 of the cold compress portion 40, and the other portion extends from the cooling bracket 20 away from the bracket head 23 into the second cooling channel 22, so that the external cooling medium in the second cooling channel 22 takes away the heat of the cold compress portion 40, thereby lowering the temperature of the cold compress portion 40 and reducing the burning sensation of the light emitted from the cold compress portion 40 on the user's skin.

[0038] Furthermore, the heat-conducting part 50 is provided with a heat-conducting plate 51 attached to the cold compressing part 40 and a heat sink assembly 52 attached to the heat-conducting plate 51, the heat-conducting plate 51 is fixed on the cooling bracket 20, and the end of the heat-conducting plate 51 away from the cold compressing part 40 covers the second cooling channel 22, and the heat sink assembly 52 is accommodated in the second cooling channel 22 and contacts with the part of the heat-conducting plate 51 covering the second cooling channel 22.

[0039] In this embodiment, the heat conducting plate 51 is a flat plate. The heat conducting plate 51 is sealed by stacking two plates, and a heat conducting net is arranged between the two plates. A heat conducting medium is also arranged between the two plates of the heat conducting plate 51, and the heat conducting net is fully in contact with the heat conducting medium, so that the contact area of ​​the heat conducting medium contacting the two plates and the heat conducting net is increased, and the heat conducting medium can quickly absorb the heat absorbed by the heat conducting plate 51 from the cold compress part 40, and quickly conduct the heat to the heat sink assembly 52, so that the heat can be dissipated by the heat sink assembly 52. ​​The heat conducting plate 51 is a short heat conducting plate, that is, the distance between the heat conducting plate 51 contacting the cold compress part 40 and the heat sink assembly 52 is short, so that the heat conducting plate 51 can conduct the heat to the heat sink assembly 52 more quickly, so that the heat sink assembly 52 can quickly use the cooling medium in the second cooling channel 22 to take away the heat, so as to achieve rapid cooling of the cold compress part 40, so as to improve the cooling rate of the hair removal device 100 with dual cooling channels.

[0040] Optionally, the two plates of the heat conducting plate 51 are both copper plates. The heat conducting mesh is a copper mesh with a capillary structure, so that the contact area between the heat conducting medium and the two plates is increased and more even, thereby improving the heat conducting efficiency of the heat conducting plate 51 .

[0041] Optionally, a vacuum sealed cavity is provided between the two plates of the heat conducting plate 51, and the heat conducting medium and the heat conducting net are accommodated in the sealed cavity.

[0042] Optionally, the heat conducting medium of the heat conducting plate 51 is a coolant, preferably water.

[0043] Optionally, the edges of the two plates of the heat conducting plate 51 are sealed and pressed together, so that the structure of the heat conducting plate 51 is stable and heat is prevented from entering the heat conducting plate 51 .

[0044] In this embodiment, the heat sink assembly 52 includes a plurality of side-by-side heat sinks 522 attached to the heat conducting plate 51. The heat sink 522 is in contact with the heat conducting plate 51 to increase the contact area between the heat sink assembly 52 and the heat conducting plate 51, and the heat conducting plate 51 can be used to seal the second cooling channel 22 to prevent leakage of the external cooling medium in the second cooling channel 22. The heat sink 522 can quickly absorb the heat of the heat conducting plate 51. There is a cooling medium flow space between the plurality of heat sinks 522, and the cooling medium flow direction between the plurality of heat sinks 522 is consistent with the extension direction of the second cooling channel 22, so that the cooling medium in the second cooling channel 22 can quickly flow through the flow space between the plurality of heat sinks 522, thereby realizing that the cooling medium in the second cooling channel 22 can quickly absorb the heat of the heat sink 522 and take the heat away, thereby realizing effective heat dissipation of the heat conducting plate 51.

[0045] Furthermore, the cooling bracket 20 is provided with a bottom shell 24 and a top shell 25 covering the bottom shell 24, the heat conducting plate 51 is fixed to the side of the top shell 25 facing away from the bottom shell 24, a part of the cold compress part 40 is fixed between the bottom shell 24 and the top shell 25, and another part passes through the top shell 25 to contact the heat conducting plate 51, the first cooling channel 21 is formed between the bottom shell 24 and the top shell 25, and the second cooling channel 22 is formed between the bottom shell 24 and the heat conducting plate 51.

[0046] In this embodiment, the top shell 25 is provided with a notch 251 communicating with the second cooling channel 22, and the heat conducting plate 51 covers the notch 251, so that the heat conducting part 50 can seal the notch 251, so that a part of the heat conducting part 50 can extend into the second cooling channel 22. The heat sink 522 is completely accommodated in the second cooling channel 22. A receiving groove communicating with the first cooling channel 21 is also provided between the top shell 25 and the bottom shell 24. The cold compress part 40 is fixed to the receiving groove, so that the light of the hair removal device 30 can irradiate the cold compress part 40. The heat conducting surface 42 extends out of the receiving groove from the top shell 25. The cold compress surface 41 extends out of the receiving groove from the end surface of the bracket head 23, so that the cold compress surface 41 can contact the user's skin. The top shell 25 effectively supports the heat conducting plate 51, and the size of the heat conducting plate 51 is comparable to that of the top shell 25, so that the internal structure of the hair removal device 100 with dual cooling channels is more compact, and the volume of the hair removal device 100 with dual cooling channels can be effectively reduced for easy carrying.

[0047] In one embodiment, the cooling bracket 20 is provided with a first transmission port 26 connecting the first cooling channel 21 and the second cooling channel 22 and away from the first driving port 11, and the first transmission port 26 is arranged between the top shell 25 and the bottom shell 24. The first transmission port 26 is arranged on the side wall of the cooling bracket 20 adjacent to the cold compress part 40 and away from the first driving port 11.

[0048] Specifically, half of the first transfer port 26 is provided on the top shell 25, and the other half is provided on the bottom shell 24. The first transfer port 26 is provided on the side wall of the cooling bracket 20 adjacent to the cold compress portion 40, and the first drive port 11 is docked with the other side wall of the cooling bracket 20. The cooling bracket 20 is provided with a boss 27 on the other side wall adjacent to the cold compress portion 40, and the boss 27 is provided with a second transfer port 271. The shell 12 is engaged with the boss 27 so that the first drive port 11 is docked with the second transfer port 271. The first cooling channel 21 and the second cooling channel 22 are formed between the second transfer port 271 and the first transfer port 26. The cooling drive portion 10 is provided on one side of the cooling bracket 20, so that the first drive port 11 blows the cooling medium to the second transfer port 271 and discharges the cooling medium from the first transfer port 26. The internal cooling medium of the cooling bracket 20 is blown into from the side of the cooling bracket 20 and blown out from the other side of the cooling bracket 20, so that the flow rate of the cooling medium in the first cooling channel 21 and the second cooling channel 22 is increased, thereby increasing the heat dissipation efficiency.

[0049] For further information, see Figure 3 The hair removal device 100 with dual cooling channels also includes a shell 60 , in which the cooling drive unit 10 , the cooling bracket 20 and the heat conducting unit 50 are all fixed. The shell 60 is provided with a first guide port 61 docking with the first transmission port 26 .

[0050] In this embodiment, the housing 60 includes an upper housing and a lower housing, and the upper housing and the lower housing can be assembled by screw connection or clamping, or can be integrally processed. Optionally, the upper housing and the lower housing are assembled by a clamping method of snap-fitting, so as to facilitate the disassembly and maintenance of the upper housing and the lower housing. The first guide port 61 is arranged at the joint of the upper housing and the lower housing. The housing 60 is provided with a receiving space, and the cooling drive unit 10, the cooling bracket 20 and the heat conducting unit 50 are all fixed in the receiving space. The first guide port 61 is docked with the first transmission port 26, so that the cooling medium entering the cooling bracket 20 can be quickly discharged from the first guide port 61, so as to avoid the cooling medium that has absorbed heat from flowing back into the cooling bracket 20 again. Of course, there can also be a certain distance between the first guide port 61 and the first transmission port 26, so that the cooling medium discharged from the first guide port 61 can be partially discharged from the housing 60 from the first transmission port 26, or partially enter the housing 60, so that the cooling medium can continue to cool other components in the housing 60. The first guide port 61 may be a suction port or an outlet port.

[0051] Furthermore, the cooling drive unit 10 is provided with a second drive port 13 , and the housing 60 is provided with a second guide port 64 docking with the second drive port 13 .

[0052] In this embodiment, the second drive port 13 is arranged at the part of the shell 12 close to the upper shell, and the second guide port 64 is arranged at the upper shell. The second drive port 13 and the second guide port 64 can be sealed and docked, so that the second drive port 13 directly sucks the external cooling medium into the shell 12 through the second guide port 64. The shell 60 protects the cooling drive unit 10, and the cooling drive unit 10 directly sucks the external cooling medium through the second guide port 64, reducing the resistance of the cooling drive unit 10 to drive the cooling medium to flow, increasing the cooling medium flow rate, and increasing the internal heat dissipation rate of the hair removal device. Of course, there can also be a certain distance between the second drive port 13 and the second guide port 64, so that a part of the cooling medium entering from the second guide port 64 can be quickly sucked into the cooling drive unit 10 and blown into the first cooling channel 21 and the second cooling channel 22, and the other part can enter the shell 60, thereby cooling down other components in the shell 60.

[0053] In this embodiment, the housing 60 is provided with a head 65 and a gripping portion 66 opposite to the head 65, the cold compress portion 40 is arranged on the peripheral side of the head 65, the first guide port 61 is arranged at the end of the head 65, and the second guide port 64 is arranged at the connection between the gripping portion 66 and the head 65. Specifically, the gripping portion 66 is opposite to the head 65, so that the user can adjust the direction of the head 65 after grasping the gripping portion 66, thereby facilitating the adjustment of the position of the cold compress portion 40 in contact with the user's body. The housing 60 is generally in the shape of a straight tube, and the cold compress portion 40 is arranged on the side wall of the straight tube, so that the user can rotate and adjust the direction of the cold compress portion 40 after grasping the gripping portion 66. The first guide port 61 is arranged at the end of the head 65, and the first guide port 61 can quickly dissipate heat from the hair removal device 30 and the cold compress portion 40. The second guide port 64 is located at the connection between the head 65 and the gripping portion 66, so that the cooling drive portion 10 is located at the connection between the gripping portion 66 and the head 65, thereby reducing the size of the hair removal device 100 with dual cooling channels and making it easier to carry.

[0054] More specifically, the shell 60 also has a tail portion 67 opposite to the head portion 65, and the tail portion 67 is provided with a third guide port 671. The third guide port 671 can discharge the cooling medium in the shell 60, so that the cooling medium that enters the shell 60 and outside the cooling bracket 20 absorbs the heat of other components in the shell 60 and is discharged from the third guide port 671, thereby achieving cooling of the entire interior of the hair removal device 100 with dual cooling channels.

[0055] In another embodiment, see Figure 4 ,and Figure 3 The illustrated embodiments are substantially the same, except that the first drive port 11 is docked with the cooling bracket 20 away from the cold compress portion 40. Specifically, the cooling drive portion 10 is located on the side of the cooling bracket 20 away from the cold compress portion 40, so that the first drive port 11 transmits the cooling medium toward the cold compress portion 40. However, the transmission directions of the first cooling channel 21 and the second cooling channel 22 are both substantially perpendicular to the direction of the first drive port 11. The second transmission port 271 is provided at one end of the cooling bracket 20 away from the cold compress portion 40. After the cooling medium of the first drive port 11 enters the second transmission port 271, it needs to turn and enter the first cooling channel 21 and the second cooling channel 22, and finally be discharged from the first transmission port 26.

[0056] More specifically, the housing 60 is provided with a head 65, a tail 67 opposite to the head 65, and a peripheral side portion 69 arranged between the head 65 and the tail 67, the cold compress portion 40 is arranged on the head 65, and the first guide port 61 and the second guide port 64 are arranged on the peripheral side portion 69. The cooling bracket 20 and the cooling drive portion 10 are sequentially arranged on the head 65 and the peripheral side portion 69, so that the cooling drive portion 10, the cooling bracket 20 and the cold compress portion 40 are arranged in a straight line, thereby simplifying the structure of the depilatory device. By arranging the head 65, the peripheral side portion 69 and the tail 67 roughly side by side, the depilatory device 100 with dual cooling channels is roughly in a straight cylindrical shape, so that the depilatory device 100 with dual cooling channels is convenient to carry.

[0057] For further information, see Figure 1 and Figure 5 The hair removal device 30 includes a lamp tube 31, a lamp tube holder 32 and a reflective plate 33. The lamp tube holder 32 is fixed in the cooling bracket 20 and is close to the cold compress part 40. The lamp tube 31 and the reflective plate 33 are fixed on the lamp tube holder 32. The reflective plate 33 is located on the side of the lamp tube 31 away from the cold compress part 40. The reflective plate 33 reflects the light of the lamp tube 31 and concentrates it on the cold compress part 40.

[0058] In this embodiment, the lamp tube 31, the reflector plate 33 and the lamp holder 32 are all located in the first cooling channel 21. The lamp tube 31, the reflector plate 33 and the lamp holder 32 are all fixed in the first cooling channel 21 near the cold compress part 40 to reduce the light path emitted by the lamp tube 31, avoid the heat of the emitted light from being transferred to more devices, and reduce the heat accumulation in the first cooling channel 21. More specifically, the lamp holder 32 is fixed between the bottom shell 24 and the top shell 25, so that the lamp holder 32 and the cooling bracket 20 have a stable structure. The lamp tube 31, the reflector plate 33 and the lamp holder 32 are adjacent to the first transmission port 26, so that the cooling medium can immediately discharge the heat from the first transmission port 26 after absorbing the heat of the lamp tube 31, the reflector plate 33 and the lamp holder 32, effectively reducing the heat of the lamp tube 31, the reflector plate 33 and the lamp holder 32. The reflector plate 33 focuses and reflects the light of the lamp tube 31, increasing the light concentration of the cold compress part 40. The two ends of the reflector 33 have openings, so that the cooling medium flows from one open end to the other open end of the reflector 33, and the external cooling medium contacts the surrounding side of the lamp tube 31 to form convection, which effectively cools the lamp tube 31. The two open ends of the reflector 33 are respectively adjacent to the first transmission port 26 and the second transmission port 271, so that the cooling medium in the first cooling channel 21 quickly flows through the inner side of the reflector 33, so as to improve the heat dissipation efficiency of the lamp tube 31.

[0059] Furthermore, the hair removal device 100 with dual cooling channels also includes a control device 70, which includes a circuit board, a processor and a capacitor. The processor is arranged on the circuit board, the capacitor is electrically connected to the circuit board, and the circuit board is electrically connected to the cold compress part 40 and the hair removal device 30.

[0060] In this embodiment, the hair removal device 30 is electrically connected to the control device 70, and the control device 70 can provide power to the hair removal device 30 and control the operation of the hair removal device 30, so that it can be used without plugging in an external circuit. It can also directly use an external power source, such as a dry capacitor or a storage capacitor, so that it is easy to store and carry, and can be used outside. The control device 70 can also be connected to an external circuit for charging, and can control the start and stop, power regulation, heat protection, etc. of the hair removal device 100 with dual cooling channels.

[0061] It is understandable that the internal heat of the conventional hair removal device is high, which may easily cause short circuit, burning, explosion and other dangers to the components inside the hair removal device. The heat conducting plate 51 of the present application utilizes the cooling medium in the second cooling channel 22 to effectively cool the cold compress part 40, and the hair removal device 30 utilizes the cooling medium in the first cooling channel 21 to effectively dissipate heat, so that the cold compress part 40 can effectively cool the user's skin with high comfort and without causing damage to the skin. In addition, the temperature of the hair removal device 30 is effectively reduced, and the cooling medium can also be used to cool other components inside the hair removal device 100 with dual cooling channels, so that the body of the hair removal device 100 with dual cooling channels is cooled as a whole, thereby preventing the internal temperature of the hair removal device 100 with dual cooling channels from being too high and causing harm. Specifically, the control device 70 of the hair removal device 100 with dual cooling channels of the present application will generate heat when working. The cooling drive unit 10 can also drive the external cooling medium to flow into the shell 60 and contact the control device 70, and use the external cooling medium to conduct the heat of the control device 70, so as to achieve rapid cooling of the internal components and the control device 70 of the hair removal device 100 with dual cooling channels, avoid excessive heat in the accommodation space of the hair removal device 100 with dual cooling channels, and prevent the hair removal device 30, the control device 70 and other devices from short circuiting, burning, and explosion. Dangerous situations.

[0062] In this embodiment, the control device 70 is disposed inside the housing 60, and can be optionally disposed at a place where the cooling bracket 20 is away from the cold compress part 40. The control device 70 is disposed on a side of the hair removal device 30 away from the cold compress part 40, that is, a side of the hair removal device 30 away from the human skin. This design expands the contact range of the external cooling medium allowed to contact in the accommodation space, so as to achieve the overall cooling effect of the inside of the housing 60.

[0063] In this embodiment, the control device 70 includes a circuit board fixed to the inner side of the lower shell, a processor fixed on the circuit board, and a capacitor fixed to the inner side of the lower shell. The circuit board is fixed in the outer shell 60 near the cooling bracket 20. The processor processes the electrical signal of the depilatory device 30 to control the operation of the depilatory device 30. The capacitor provides electrical energy to the depilatory device 30, the cooling drive unit 10, the circuit board, and the processor.

[0064] Furthermore, the cold compress part 40 is provided with a cold compress 43 and a refrigeration part 44 for cooling the cold compress 43, wherein the cold compress 43 is used to fit the user's skin and provide a cold compress. The refrigeration part 44 is provided with a refrigeration surface 441 that fits the cold compress 43, and the refrigeration surface 441 is arranged opposite to the heat conducting surface 42. The heat conducting plate 51 fits the heat conducting surface 42 to absorb the heat of the heat conducting surface 42.

[0065] In this embodiment, the lamp tube 31 and the refrigeration element 44 are electrically connected to the circuit board, and the refrigeration element 43 is clamped on the cooling bracket 20, so that the refrigeration element 44 is firmly fixed between the refrigeration element 43 and the cooling bracket 20, so that the heat conducting plate 51 is in contact with the refrigeration element 44. The refrigeration element 44 is closely attached to the refrigeration element 43 to cool the refrigeration element 43. A filter is also provided between the refrigeration element 43 and the lamp tube 31 to prevent the heat of the lamp tube 31 from being transferred to the refrigeration element 43. The reflector 33 is provided on the side of the lamp tube 31 away from the refrigeration element 43, so that the light emitted by the lamp tube 31 is concentrated on the refrigeration element 43.

[0066] Preferably, the cold compress 43 is made of a crystal material, specifically sapphire, K9 glass, crystal glass, as long as the material is light-transmitting crystal, and sapphire material can be selected.

[0067] It can be understood that since the cold compress 43 is made of sapphire, the cold compress 43 can also be used as a light outlet. When the lamp tube 31 emits light, the sapphire has a strong thermal conductivity, so that the cooling element 44 and the cold compress 43 can efficiently generate heat exchange, thereby achieving the best cooling effect. Optionally, the cold compress 43 can be a circular plate or a rectangular plate, which is not limited here. The side of the cold compress 43 away from the lamp tube 31 contacts the human body, and the contact surface can be a curved surface or a plane, preferably a plane.

[0068] In this embodiment, the lamp tube 31 may be an IPL lamp tube, which is located on the side of the cold compress 43 away from the human body, and the light emitted by the lamp tube 31 is emitted to the user's skin through the cold compress 43. The color of the light emitted by the lamp tube 31 is not limited, and can be colored light, composite light, etc. The specific wavelength and frequency are determined according to the usage.

[0069] In this embodiment, the hair removal device 100 with dual cooling channels is provided with a skin detection unit, which can be integrated into the cold compress 43. The skin detection unit is electrically connected to the circuit board using the capacitance touch detection principle. When the cold compress 43 contacts the skin, the internal preset capacitance detection device simultaneously detects whether the hair removal device 100 with dual cooling channels actually contacts the skin, thereby reducing safety issues caused by user's erroneous operation.

[0070] In this embodiment, the shape of the reflector 33 is not limited, and the light of the lamp tube 31 is only required to be concentrated toward the cold compress 43. Optionally, the reflector 33 is U-shaped, and the opening of the reflector 33 is arranged toward the cold compress 43. The lamp tube 31 is located at the center of the U-shaped opening of the reflector 33, which not only concentrates the light, but also prevents the heat of the lamp tube 31 from being dissipated to other places during operation.

[0071] In this embodiment, the cooling element 44 may be a cooling element of a semiconductor cooling method.

[0072] It can be understood that due to the particularity of the principle of the light hair removal technology adopted by the hair removal device 100 with dual cooling channels, a large amount of heat will be generated when the light is emitted. At the same time, when the cold compress 43 contacts the skin of the user, in order to prevent the light from causing the user a burning pain, a cooling structure needs to be provided inside the main body of the hair removal device 100 with dual cooling channels. No matter which cooling method is used, heat will be generated under the heat exchange. The refrigeration component 44 is close to the heat conduction plate 51, so that the cold compress 43 can be cooled quickly. In addition to the heat generated by the refrigeration component 44, a plurality of heating devices are also arranged in the accommodating space, and the external cooling medium in the outer shell 60 can effectively cool the plurality of heating devices.

[0073] It can be understood that the external cooling medium is sucked in from the second guide port 64, enters the second drive port 13, and then is transmitted to the cooling bracket 20 through the first drive port 11, and then passes through the hair removal device 30 and the heat sink assembly 52 along the way, so that the temperature of the lamp tube 31 decreases, and the temperature of the heat conduction plate 51 and the cold compress part 40 decreases. After entering the housing 60, part of the cooling medium flows through the circuit board, the processor and the capacitor, and is finally discharged from the third guide port 671, so that the area where the external cooling medium passes along the way is cooled.

[0074] Based on the above arrangement of separating the first cooling channel 21 and the second cooling channel 22 in the hair removal device 100 with dual cooling channels, in some embodiments, the heat dissipation method of the hair removal device 100 with dual cooling channels may not use fan cooling, but may also use other external cooling media, such as water, coolant, etc., as long as the external medium can take away the heat of the cooling channel.

[0075] The contact end surface of the cold compress part 40 with the skin and the exposed end surface of the skin detection part are arranged on the same side, so that when the skin is subjected to light hair removal, the cold compress part 43 contacts the irradiated area of ​​the skin, and applies a cold compress to cool the irradiated skin to alleviate the burning sensation caused by the irradiated skin. The cold compress part 43 can be as low as close to zero degrees, and can truly make the skin near the light outlet reach a temperature as close to the freezing point as possible, which can alleviate the burning sensation of the skin, and short-term contact will not cause skin damage.

[0076] In some embodiments, a hair removal device 100 with dual cooling channels is provided with a light source and utilizes the structural features described in all the above embodiments.

[0077] Those skilled in the art should also understand that if all or part of the components of the hair removal device 100 with dual cooling channels of the present application are combined by fusion, physical connection, etc., such as moving the positions of the components in the hair removal device 30; or setting them as one; or designing them to be detachable; and replacing the number of features, changing the features that are not used for their functions, all the combined components can form a device with specific functions, and using such a device to replace the corresponding components of the present invention also falls within the protection scope of the present invention.

[0078] Compared with the prior art, the hair removal device 100 with dual cooling channels of the present application has the following advantages:

[0079] 1. The cooling bracket 20 is provided with a first cooling channel 21 and a second cooling channel 22, both of which are connected to the first driving port 11 of the cooling driving part 10, and the hair removal device 30 is fixed in the first cooling channel 21, and a part of the heat conduction part 50 is in contact with the cold compress part 40, and the other part is arranged in the second cooling channel 22, so that the heat dissipation of the heat conduction part 50 and the heat dissipation of the hair removal device 30 are separated, thereby effectively improving the overall cooling efficiency inside the hair removal device.

[0080] 2. The hair removal device 100 with dual cooling channels adopts a heat conducting plate 51 of a composite structure. The heat conducting plate 51 utilizes two overlapping plates and a heat conducting medium and a heat conducting net sealed between the two plates to increase the heat conducting efficiency of the heat conducting plate 51. The heat conducting plate 51 absorbs the heat of the cold compress part 40, so that the heat of the cold compress part 40 is quickly reduced. The heat conducting plate 51 is made of copper, which increases the heat conducting efficiency of the heat conducting plate 51, can effectively and quickly absorb heat, and effectively and quickly dissipate heat.

[0081] 3. In the past, only the refrigeration element 44 of the cold compress part 40 was protected and ventilated by a sealed cavity, but the hair removal device 30 and the control device 70, which also generate heat, were not considered. Especially when used for a long time, the heat of the hair removal device 30 and the lamp 31 will be very high, so the cooling effect is not thorough. The hair removal device 100 with dual cooling channels of the present application uses the cold compress part 40 and the hair removal device 30 to cool down separately, so that the overall cooling effect is greatly improved, and the overall temperature inside the hair removal device 100 with dual cooling channels is effectively reduced.

[0082] 4. The external cooling medium that can be utilized by the technical means of the present application can be not only air introduced by a fan, but also other cooling media, such as using a water pump to extract water or coolant.

[0083] 5. The first guide port 61 is arranged on one side of the head 65 so that the cooling medium can be discharged quickly, thereby improving the heat dissipation efficiency of the cold compress portion 40 and the hair removal device 30. The third guide port 671 is arranged at the tail portion 67 of the hair removal device 100 with dual cooling channels away from the cold compress portion 40, so that the cooling medium is discharged after the flow path distance in the hair removal device 100 with dual cooling channels is lengthened, and the heat flowing through the control device 70 is discharged, thereby reducing the temperature of the control device 70.

[0084] 6. The cold compress 43 is exposed from the head 65 of the shell 60 and is in actual contact with human skin, so that the user can feel the cold compress effect of the cold compress 43 while using the hair removal device 100 with dual cooling channels to remove hair, thereby reducing the strong pain caused by the heat brought by the hair removal device 100 with dual cooling channels.

[0085] 7. The cold compress 43 is made of a crystal material, which may be sapphire. Sapphire has a strong thermal conductivity, which can reduce the heat of the light emitted by the emitter of the double cooling channel hair removal device 100 while maintaining the light transmittance.

[0086] 8. The refrigeration element 44 can be a semiconductor refrigeration sheet, which can effectively improve the cooling effect of the hair removal device 100 with dual cooling channels.

[0087] 9. The hair removal device 100 with dual cooling channels is provided with a skin detection unit. When the cold compress unit 40 contacts the skin, the skin detection unit will detect whether the machine actually contacts the skin, which can reduce the safety problems caused by the user's incorrect operation and improve the working efficiency of the hair removal device 100 with dual cooling channels.

[0088] The above is an implementation method of the embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the embodiment of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
