Abstract
Description
[Technical Field]
[0001] The present application relates to the field of epilators, and in particular to epilators. [Background technology]
[0002] Epilators tend to generate a lot of heat during operation, and this heat is mainly generated from the lamp during operation. As a key component of an epilator, the lamp generates a lot of heat during operation. If the heat is not dissipated in a timely manner, the lamp's service life will be shortened. The heat generated from the lamp is also radiated to other parts of the epilator, such as the part that comes into contact with the skin, and if the temperature of that part rises, the user will feel a burning sensation during use. In addition, commercially available epilators have the problem of uneven light output during operation.
[0003] Furthermore, in the practical application of a hair removal device, it is difficult to maintain close contact between the trigger wire and the lamp, and if the trigger wire and the lamp become loose, it will not only be difficult to trigger the trigger wire to light the lamp, but also the cost of triggering the trigger wire to light the lamp will be high. Summary of the Invention
[0004] The present application mainly provides a hair removal device that solves the problem of poor heat dissipation during operation of the hair removal device.
[0005] In order to solve the above technical problems, one technical solution adopted in this application is to provide a hair removal device, which includes a reflector, a light source, and a holder, the reflector is a conductor and can reflect light, the light source is a rod-shaped gas excitation light source that is disposed opposite the reflector and can be excited by the reflector to emit the light after the reflector is energized, and the reflector is fixed to the holder, and the distance between the light source body and the reflector is greater than 0 and less than or equal to 0.3 mm. When the reflector is energized, it generates a high voltage that ionizes the gas in the light source to generate an arc and further discharge, thereby allowing the light source to emit light.
[0006] The present application has the following beneficial effects: When the epilator is in operation, the reflector generates a high electric field within it when energized, generating a high voltage that ionizes the gas in the light source, creating an arc and further discharging electricity, thereby enabling the light source to emit light. By limiting the distance between the light source and the reflector, the voltage within the reflector can excite the light source to emit light. Compared to the method of triggering the lamp to emit light via a trigger wire, the reflector 1, which triggers the lamp to emit light without a trigger wire, not only improves the method of triggering the lamp to emit light, but also saves materials and reduces manufacturing costs.

It should be understood that the drawings in the following description are only some embodiments of the present application, and those skilled in the art can obtain other drawings based on these drawings without any creative efforts.

[0012] 1 and 2, the present application discloses a hair removal device, which includes a reflector 1, a light source 2, and a light-transmitting body 3. The light source 2 is assembled in the reflector 1, and the light source 2 can emit light. The reflector 1 can reflect the light emitted by the light source 2. The light-transmitting body 3 has an incident surface 31 for receiving light and an exit surface 32 for emitting light. After being reflected by the reflector 1, the light emitted by the light source 2 can be uniformly emitted from the exit surface 32 of the light-transmitting body 3, thereby improving the light-emission uniformity of the hair removal device and enhancing the hair removal effect of the hair removal device.
[0013] Optionally, the structures and relative positions of the light source 2, reflector 1, and light-transmitting body 3 satisfy the condition that the light emission uniformity of the emission surface 32 is 90% or more, or the light spot on the emission surface 32 occupies at least 95% of the emission surface 32. By ensuring that the light emission uniformity of the emission surface 32 is 90% or more, the hair removal effect of the epilator can be improved and hair can be uniformly removed from the target skin area. Similarly, by ensuring that the light spot on the emission surface 32 occupies at least 95% of the emission surface 32, hair can be uniformly removed from the target skin area and the light utilization rate can be improved.
[0014] Epilators with low light emission uniformity or a small ratio of light spots on the emission surface 32 to the total light emission surface 32 may require multiple irradiations of the same area to achieve uniform hair removal. Otherwise, hair removal will be ununiform and undesirable from an aesthetic standpoint. In an embodiment of the present application, the structure and relative positional relationship of the light source 2, reflector 1, and light-transmitting body 3 satisfy the conditions that the light emission uniformity of the emission surface 32 is 90% or more, or that the light spots on the emission surface 32 occupy at least 95% of the emission surface 32, thereby eliminating the need for the epilator to irradiate the same area multiple times. If the quality of the light source 2 and the power of the epilator are sufficient and meet human health requirements, the epilator can achieve efficient and uniform hair removal with just a single irradiation. At the very least, this reduces the number of repeated irradiations of the same area of skin.
[0015] Optionally, the centers of the reflector 1, the light source 2 and the light transmitting body 3 may be on a straight line, and by adjusting the distance between the three on the straight line, it is possible to make the light emission uniformity of the emission surface 32 90% or more, or to make the light spot on the emission surface 32 occupy at least 95% of the emission surface 32. Optionally, the structures of the three can be adjusted to make the epilator meet the above conditions.
[0016] Optionally, the epilator may be adapted to meet the above requirements by designing the structures of the reflector 1, the light source 2, and the light transmitting body 3. Furthermore, the structures of the three components and the relative positions of the three components may be comprehensively designed to meet the above requirements.
[0017] The epilator further includes a heat dissipation base 4 and a holder 5, and the heat dissipation base 4 is used together with the holder 5 to assemble the reflector 1 and the light transmitting body 3 into one unit.
[0018] Optionally, referring to FIG. 3 , the epilator may further include a carbon-containing layer 91 provided on the reflector 1. For example, the carbon-containing layer 91 may be provided on the side of the reflector 1 facing away from the light source 2. The light source 2 generates heat during use and concentrates the heat on the reflector 1. The carbon-containing layer 91 has excellent thermal conductivity, which accelerates the heat conduction rate of the reflector 1 on which it is provided, improves the heat dissipation performance of the reflector 1, and prevents damage to the epilator itself due to excessive heat, as well as irritation and damage to the user's skin.
[0019] Optionally, the carbon-containing layer 91 is provided on the heat dissipation base 4. For example, the carbon-containing layer 91 may be provided between the heat dissipation base 4 and the reflector 1, thereby promoting the heat conduction rate between the heat dissipation base 4 and the reflector 1.
[0020] Optionally, the carbon-containing layer 91 may further be provided on the exposed surface of the heat dissipation base 4 , thereby improving the heat dissipation performance of the heat dissipation base 4 .
[0021] Optionally, the carbon-containing layer 91 may be a material such as graphene material, graphite powder, graphite sheet, or graphite film, and may be provided by plating, spraying, laminating, or the like, wherever a carbon-containing layer 91 as described herein can be provided.
[0022] Optionally, the heat dissipation base 4 may be a ceramic base, which can reduce the temperature within the reflector 1, further control the temperature of the reflector 1, improve the performance of the reflector 1, and enable the reflector 1 to better reflect light. If the temperature within the reflector 1 is not reduced, on the one hand, the light source 2 itself will be damaged due to high temperatures, shortening its service life. On the other hand, the heat will be radiated to other parts of the epilator, especially the parts that come into contact with the skin, causing the user to feel a burning sensation due to the high temperatures, making it difficult to use. In an embodiment of the present application, the ceramic base can reduce the temperature within the reflector 1, that is, transfer heat within the reflector 1 through thermal conduction, thermal convection, thermal radiation, or any combination of the above three methods, reducing the temperature within the reflector 1 and further allowing the light source 2 to dissipate heat evenly, thereby improving the heat dissipation efficiency of the epilator.
[0023] Optionally, one side of the heat dissipation base 4 is provided with a slot 41, which may be rod-shaped, and the reflector 1 is embedded in the slot 41; the holder 5 has a window 51, which may be square or have any other shape compatible with the shape of the light-transmitting body 3, and the light-transmitting body 3 is embedded in the window 51 and located on one side of the opening of the reflector 1. The heat dissipation base 4 and the holder 5 are detachably connected, which makes it easy to assemble and disassemble the epilator.
[0024] Optionally, a first fastener 42 is integrally formed on both sides of the heat dissipation base 4, and a second fastener 52 is integrally formed on both sides of the holder 5, and the first fastener 42 and the second fastener 52 are provided correspondingly. When the heat dissipation base 4 and the holder 5 are connected, the first fastener 42 and the second fastener 52 are firmly engaged with each other, which further ensures that the heat dissipation base 4 and the holder 5 are connected securely, thereby improving the stability of the epilator when in use.
[0025] Optionally, the first fastener 42 may be a locking block or a cantilever hook, and the second fastener 52 may be a mounting hole. When the cantilever hook is embedded in the mounting hole, the mounting hole restricts the cantilever hook from easily coming out of the mounting hole, ensuring a secure connection between the first fastener 42 and the second fastener 52. This means that the heat dissipation base 4 and the holder 5 can be fixed relative to each other, effectively preventing the heat dissipation base 4 and the holder 5 from loosening or coming off.
[0026] Optionally, the optically transparent body 3 may be crystalline.
[0027] 1, 2 and 4, the reflector 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 reflector 1, and the second reflective area 12 is a planar area extending outward from both ends of the arc-shaped area, and the planar area is adjacent to the arc-shaped area. After the light source 2 emits light, the reflector 1 reflects the light to the light-transmitting body 3.
[0028] Optionally, the reflector 1 may be semicircular, and the light source 2 may be a rod-shaped lamp. The rod-shaped lamp emits light, and the arc-shaped region of the reflector 1 can effectively reflect the light to the light-transmitting body 3. At the same time, the planar region of the reflector 1 can also reflect the light to the light-transmitting body 3. By sufficiently reflecting the light by the arc-shaped region and the planar region, the light output rate is increased and the light utilization rate is improved.
[0029] Optionally, the reflector 1 may be rod-shaped.
[0030] 5 , optionally, the center of the light source 2 is located between the focal point of the reflector 1 and the bottom of the reflector 1, the incident surface 31 of the optically transparent body 3 is located between the exit surface 32 and the focal point of the reflector 1, and the focusing position of the light reflected from the reflector 1 is between the exit surface 32 of the optically transparent body 3 and the focal point of the reflector 1. By limiting the positions of the light source 2, the reflector 1, and the optically transparent body 3, the light exit uniformity of the exit surface 32 can be made to be 90% or more, or the light spot on the exit surface 32 can occupy at least 95% of the exit surface 32, so that the light emitted by the light source 2 can be sufficiently reflected by the reflector 1 to the optically transparent body 3, thereby improving the light exit uniformity of the optically transparent body 3.
[0031] For example, when the epilator is in operation, the light source 2 emits light, and the first reflective area 11 and the second reflective area 12 of the reflector 1 sufficiently reflect the light to the light-transmitting body 3, so that the light enters the light-transmitting body 3 through the incident surface and then exits the light-transmitting body 3 through the exit surface, thereby making the light emission uniformity of the exit surface 32 more than 90%, or making the light spot on the exit surface 32 occupy at least 95% of the exit surface 32, thereby improving the light emission uniformity of the epilator and improving the use effect of the epilator.
[0032] Optionally, the angle between the planar region and the reference line is 5 to 20 degrees, and the reference line is a line connecting the center of the light source 2 and the center of the light transmitting body 3. By limiting the angle between the planar region and the reference line so that light can be sufficiently reflected by the light transmitting body 3, on the one hand, light waste can be reduced and usage costs can be cut, and on the other hand, the light emission uniformity of the light transmitting body 3 can be improved.
[0033] In another embodiment of the epilator according to the present application, the light source 2 is provided near the bottom of the reflector 1, and the reflector 1 does not have a planar area at an angle of 5 to 20 degrees relative to the reference line. In this case, there is a high possibility that the light will be reflected multiple times. Depending on the incident angle, there is a high possibility that the light will be reflected multiple times, and the exit angle will be unstable and difficult to control.
[0034] By limiting the angle between the planar area and the reference line, the light can have a good exit angle when emitted from the reflector 1, and at the same time, the light can be concentrated, thereby improving the light exit rate, effectively avoiding light loss, and enhancing the light distribution effect.
[0035] Furthermore, the angle between the planar region and the reference line is 8 to 15 degrees, and the angle may be 8 degrees or 15 degrees. For example, in this range, the focal length is close, and under the condition that light emission uniformity and light utilization rate are satisfied, the light transmitting body 3 can also be brought closer to the light source 2, which makes the structure of the epilator more compact and also saves materials for processing.
[0036] By setting the angle between the planar region and the reference line to 8 to 15 degrees, the focal distance becomes closer, the light transmitting body 3 can be located closer to the light source 2, and high light emission uniformity is ensured. When improving light emission uniformity through this structure, there is no need to improve light emission uniformity by other methods such as increasing light intensity. Under these settings, the light transmitting body 3 is closer to the light source 2, and the entire epilator can be designed to be smaller and more compact, making it easier to carry and use.
[0037] 1, the reflector 1 has side reflective members 13 integrally molded at both ends in the longitudinal direction, and the side reflective members 13 are sheet-shaped and reflect light leaking from both ends of the reflector 1 to the light-transmitting body 3. Here, the side reflective members 13 have through holes 131, and two through holes 131 may be provided, and the two through holes 131 have the same center line, and the end of the light source 2 passes through the through holes 131.
[0038] Optionally, fixing members 6 are connected to both ends of the light source 2 for movably fixing the light source 2 to the reflector 1. For example, the fixing members 6 may be soft sleeves made of silicone or rubber sleeves. The fixing members 6 are cylindrical and have mounting grooves 61. Both ends of the lamp are embedded in the mounting grooves 61. The fixing members 6 have mounting holes 62 along their axes, which communicate with the mounting grooves 61. Both ends of the lamp have mounting posts extending therefrom, which pass through the mounting holes 62. The fixing members 6 are disposed on the outside of the reflector 1.
[0039] Optionally, support blocks 43 are integrally formed on both ends of the heat dissipation base 4, and notches are formed in the support blocks 43 to accommodate both ends of the light source 2 and the fixing member 6. When the heat dissipation base 4 and the holder 5 are engaged, the fixing member 6 is fixed by the holder 5 and the support blocks 43, and the light source 2 is fixed to the reflector 1. The fixing member 6 itself has elasticity, and when the fixing member 6 is pressed during the process of being fixed by the holder 5 and the support blocks 43, the fixing member 6 can appropriately change its shape to adapt to the shape of the notches, and at the same time, damage to the lamp can be reduced and the pressing of the lamp can be minimized.
[0040] Optionally, a limiting portion 53 is provided on a side wall of the holder 5 adjacent to the fixing member 6, and the limiting portion 53 is used to limit the position of the fixing member 6. The limiting portion 53 may be a notch or a spaced tab, and the notch may have an arc shape. The limiting portion 53 allows the support block 43 and the holder 5 to securely fix the fixing member 6 and minimize loosening, thereby improving the stability of the epilator.
[0041] 1, an optical filter 7 for filtering light is provided between the optically transparent body 3 and the reflector 1. The optical filter 7 is fixed to the holder 5 to cover the window 51 and also to cover the opening of the reflector 1 facing the holder 5, and the optical filter 7 is fixed to the heat dissipation base 4. When the heat dissipation base 4 and the holder 5 are engaged, the side wall of the holder 5 that is closest to the reflector 1 is pressed against one side of the optical filter 7, and the other side of the optical filter 7 abuts against the reflector 1. The optical filter 7 filters out harmful ultraviolet light and reduces harm to the human body, thereby improving the safety of the hair removal device and improving the treatment effect at the same time.
[0042] Optionally, a pad 8 is provided between the holder 5 and the optical filter 7, the pad 8 having the same shape as the optical filter 7, the pad 8 being sheet-like and having an escape opening 81 for light to pass through, the size of the escape opening 81 being smaller than the size of the side wall of the optically transparent body 3 facing the pad 8. When the heat dissipation base 4 and the holder 5 are engaged, the optically transparent body 3 is pressed against one side of the pad 8, and the other side of the pad 8 is pressed against the optical filter 7. The pad 8 can reduce the pressure of the optically transparent body 3 on the optical filter 7 and can also reduce collisions between the optically transparent body 3 and the optical filter 7, thereby minimizing manufacturing costs on the one hand and extending the service life of the optical filter 7 on the other hand.
[0043] 11 and 12, in another embodiment of the epilator of the present application, an elastic sealing ring 16 is disposed between the optical filter 7 and the optically transparent body 3, the elastic sealing ring 16 is annular, and both the optical filter 7 and the optically transparent body 3 are fitted together to be sealed with the elastic sealing ring 16, so that condensation does not occur between the optically transparent body 3 and the optical filter 7, and some dirt cannot enter the connection point between the optically transparent body 3 and the optical filter 7, and the elastic sealing ring 16 is preferably annular.
[0044] Of course, if the epilator is accidentally dropped to the ground, a rigid-body collision may occur between the light transmitting body 3 and the ground, and in a conventional light transmitting body 3, the impact force may be transmitted to the light filter 7, further damaging the light filter 7, the reflector 1, and the light source 2. In the epilator of this embodiment, the impact force when the light transmitting body 3 collides can be counteracted by the elastic sealing ring 16, and when pressed by an external force, the elastic sealing ring 16 causes elastic deformation due to its own elasticity, thereby reducing or counteracting the impact between the light filter 7 and the light transmitting body 3, thereby reducing the possibility that the light filter 7, the reflector 1, and the light source 2 will be damaged by such impacts, and further improving the collision avoidance performance of the epilator.
[0045] 13 to 15, the elastic sealing ring 16 is provided with an inner ring 161 for transmitting light, and the light filtered by the optical filter 7 is guided to the light-transmitting body 3 through the inner ring 161 so that it can be irradiated onto human skin.
[0046] In this embodiment, both the optical filter 7 and the optically transparent body 3 are directly fixed to the holder 5 and cannot move relative to the holder 5. This effectively prevents the optically transparent body 3 from being struck by a bone or a sharp object during use, causing the optically transparent body 3 to retreat relative to the holder 5, thereby preventing irreversible deformation of the optical filter 7 or the hair removal assembly 100. Furthermore, even if the elastic sealing ring 16 is pressed multiple times and irreversible deformation occurs, it is possible to avoid wasting light energy due to the impact on the light guiding effect of the hair removal device.
[0047] The elastic sealing ring 16 further has an attachment groove 162 communicating with the inner ring 161, the attachment groove 162 being located on the side of the elastic sealing ring 16 away from the hair removal assembly 100, the inner ring 161 extending through from the bottom wall of the attachment groove 162 towards the side of the optical filter 7, the optically transparent body 3 being partially attached within the attachment groove 162, thereby improving the sealing performance between the optically transparent body 3 and the elastic sealing ring 16, and the elastic sealing ring 16 being fixed to the optically transparent body 3 to achieve a fixed connection between the two.
[0048] In a preferred embodiment, the elastic sealing ring 16 includes an outer ring 163 and a protrusion 164 protruding from one side of the outer ring 163, the protrusion 164 abutting against the optical filter 7, a mounting groove 162 is provided on the side of the outer ring 163 away from the protrusion 164, and the inner ring 161 extends from the bottom wall of the mounting groove 162 to one side of the protrusion 164, so that both the outer ring 163 and the protrusion 164 form a completely closed loop structure, and light within the inner ring 161 can only be transmitted from the light-transmitting body 3.
[0049] In a preferred embodiment, the cross section of the protrusion 164 has a transverse triangular shape, and the area of contact between the protrusion 164 and the optical filter 7 is smaller than the area of contact between the protrusion 164 and the outer ring 163. Therefore, when the elastic sealing ring 16 is installed, the end of the protrusion 164 away from the outer ring 163 may be partially warped when pressed. Because the elastic sealing ring 16 is elastic, the warped portion of the elastic sealing ring 16 can firmly abut against the optical filter 7. This means that if the gap between the optically transparent body 3 and the optical filter 7 changes slightly, the warped portion of the elastic sealing ring 16 can also adapt to this gap change. Therefore, a tight or interference fit is always maintained between the elastic sealing ring 16 and the optically transparent body 3, and between the elastic sealing ring 16 and the optical filter 7, resulting in better sealing. Of course, in other embodiments, the cross section of the protrusion 16 may have a trapezoidal shape.
[0050] In this embodiment, the elastic sealing ring 16 is an annular body made of a material that is laser-resistant and resistant to high and low temperatures, thereby preventing the elastic sealing ring 16 from being deformed by high or low temperatures or laser irradiation during use, and extending the service life of the elastic sealing ring 16.
[0051] To differentiate from the prior art, this embodiment discloses a hair removal device that includes a reflector 1, a light source 2, and a light-transmitting body 3. The light source 2 emits light, which is reflected by the reflector 1 so that the light enters the light-transmitting body 3 through its incident surface 31 and exits through its exit surface 32. The structures and relative positions of the light source 2, reflector 1, and light-transmitting body 3 satisfy the conditions that the light emission uniformity of the exit surface 32 is 90% or more, or the light spot on the exit surface 32 occupies at least 95% of the exit surface 32. By limiting the structures and relative positions of the light source 2, reflector 1, and light-transmitting body 3, the light can be emitted uniformly from the exit surface 32 of the light-transmitting body 3, thereby improving the light emission uniformity of the hair removal device and enhancing the usage efficiency of the hair removal device.
[0052] Referring to Figure 5, Figure 5 is a schematic diagram showing the structure of one embodiment of the present application. Here, the hair removal device includes a head 111 and a handle 112 connected to the head 111. The head 111 is provided with a cooling unit 1111 for contact with the skin. The cooling unit 1111 emits light to irradiate hair follicles on the user's skin, allowing the light to penetrate the skin and irradiate the hair follicles to remove hair, while also rapidly lowering the temperature, reducing the burning sensation caused by the light on the skin and preventing the user from feeling uncomfortable during use. In some embodiments, the cooling unit 1111 can also emit light for skin care, thereby allowing the hair removal device to have both hair removal and skin care functions.
[0053] Optionally, the grip portion 112 may include a hollow shell (not numbered in the figures), with air permeable holes 1211 provided on the surface of the shell, which communicate the interior of the shell with the outside world, allowing the hair removal device to exchange air with the outside world through the air permeable holes 1211 and lower the temperature inside. The shell further includes a port 1212, which can be used to connect to an external power source and charge the hair removal device. Here, the location of the port 1212 on the shell is not limited.
[0054] 6 and 7, Fig. 7 is a schematic diagram showing an exploded structure of an embodiment of the present application, where the arrows shown in Fig. 7 represent the flow direction of air in the hair removal device under the driving of the cooling driving assembly, the straight lines represent the cold air flow, and the waves represent the hot air flow. Specifically, the hair removal device may include a shell, a light cover 113 provided at the opening of the shell, a hair removal mechanism 14 housed inside the shell, and a bottom cover 15.
[0055] In this embodiment, the shell may include a first shell 121 and a second shell 122, which are connected to each other in an engaging manner to form a cavity with openings at both ends, the hair removal mechanism 14 is housed in the cavity, and the light cover 113 and the bottom cover 15 are respectively provided to cover the two openings and are used to seal the openings after the first shell 121 and the second shell 122 are connected to form the cavity.
[0056] Optionally, the first shell 121, the second shell 122, the light cover 113 and the bottom cover 15 may be connected by snaps, or may be connected by screws or adhesive.
[0057] The epilation mechanism 14 includes an epilation assembly 100 , a cooling sensation assembly 200 , a heat dissipation base 300 and a cooling drive assembly 400 .
[0058] The cooling sensation assembly 200 is provided on the side close to the light cover 113, and the light cover 113 is provided with a through-hole (not provided with a reference number), and a part of the cooling sensation assembly 200 is exposed to the outside world from the inside of the shell through the through-hole of the light cover 113 and comes into direct contact with the skin. As can be understood, a part of the cooling sensation assembly 200 and the light cover 113 form the head 111 of the hair removal device.
[0059] The hair removal assembly 100 is provided on the side of the cooling sensation assembly 200 away from the light cover 113 and is used to emit light to the cooling sensation assembly 200. The light may be visible light such as red light, green light, or yellow light. The light is incident on the cooling sensation assembly 200 and passes through the cooling sensation assembly 200 to enter the hair follicles under the skin, thereby achieving hair removal.
[0060] The heat dissipation base 300 is provided on one side of the cooling sensation assembly 200 and is connected to the cooling sensation assembly 200. When the cooling sensation assembly 200 is placed against the skin, it absorbs heat from the skin, lowering the skin temperature and reducing the burning sensation. However, if the cooling sensation assembly 200 is used for a long time, its temperature will rise and its cooling effect will decrease. The heat dissipation base 300 absorbs the heat from the cooling sensation assembly 200, maintaining the cooling sensation assembly 200 in a low-temperature working environment and ensuring the cooling effect of the cooling sensation assembly 200 on the skin. Therefore, the hair removal device of this embodiment can maintain a low temperature even when used continuously, without causing pain to the user.
[0061] The cooling drive assembly 400 is provided on the side of the heat dissipation base 300 where at least a portion of the heat dissipation base 300 faces away from the epilation assembly 100 , and is used to dissipate heat from the epilation assembly 100 and the heat dissipation base 300 .
[0062] In this embodiment, the cooling drive assembly 400 draws in the external cooling medium and introduces it into the inside of the hair removal device through the air permeation holes 1211, and the cooling medium passes through the hair removal assembly 100 and the heat dissipation base 300 to carry away heat, and then flows out through the air permeation holes 1211.
[0063] Optionally, the external cooling medium may be air, and the cooling drive assembly 400 draws in the air and blows it onto the epilation assembly 100 and the heat dissipation base 300, and the heat of the epilation assembly 100 and the heat dissipation base 300 is carried away by the airflow.
[0064] In this embodiment, the air permeation holes 1211 are provided in the first shell 121, and at least a portion of the cooling drive assembly 400 faces the air permeation holes 1211, so that the cooling drive assembly 400 can better absorb the external cooling medium through the air permeation holes 1211 and improve heat dissipation efficiency. In other embodiments, the air permeation holes 1211 may be provided in the second shell 122.
[0065] 7 and 8, FIG. 8 is a schematic diagram showing an exploded structure of the embodiment of FIG. 7, where the arrows shown in FIG. 8 indicate the direction of air exiting the fan.
[0066] In this embodiment, the hair removal device further includes a holder 500, a circuit board 600, a processor 700, and a capacitor 800, wherein the hair removal assembly 100 and the cooling sensation assembly 200 are mounted in the holder 500, and the cooling drive assembly 400 is provided adjacent to the holder 500. The hair removal assembly 100, the cooling sensation assembly 200, and the cooling drive assembly 400 are mounted on the circuit board 600 and electrically connected to the circuit board 600.
[0067] The processor 700 and the capacitor 800 are electrically connected to and mounted on the circuit board 600. When connected to an external power source, the external power source can charge the capacitor 800 so that the capacitor 800 can power the hair removal device, and the capacitor 800 can store power when connected to an external power source, allowing the hair removal device to be used even when not connected to an external power source. The processor 700 sends control commands to the hair removal assembly 100, the cooling sensation application assembly 200, and the cooling drive assembly 400 to control the operation of the hair removal device, such as controlling the switches of the hair removal device, thermal protection, power regulation, etc.
[0068] In this embodiment, the circuit board 600 may be fixed in the second shell 122, and the circuit board 600 may be selected as a PCBA circuit board.
[0069] In related art, the heat inside the hair removal device body often increases during use, and the internal circuits and components of the hair removal device are prone to explosion, burning, short circuit, etc. in a high-temperature environment. In this embodiment, the cooling drive assembly 400 can dissipate heat from the hair removal assembly 100 and the heat dissipation base 300, and the heat dissipation base 300 can dissipate heat from the cooling sensation assembly 200, so that the cooling sensation assembly 200 can ice the skin to increase skin comfort and prevent problems such as explosion, burning, short circuit, etc. caused by excessively high temperatures.
[0070] Specifically, the hair removal assembly 100 may include a light source 101 , a reflector 102 , a light filter 103 and two electrodes 104 .
[0071] The light source 101, the reflector 102 and the optical filter 103 are mounted in the holder 500, i.e., mounting locations for the light source 101, the reflector 102 and the optical filter 103 are provided in the holder 500, and the light source 101, the reflector 102 and the optical filter 103 are engaged into the mounting locations of the holder 500.
[0072] Here, the light source 101 is disposed opposite the cooling sensation assembly 200, and light emitted from the light source 101 can be directly incident on the cooling sensation assembly 200. The reflector 102 is disposed on the side of the light source 101 away from the cooling sensation assembly 200 and reflects the light from the light source 101 to the cooling sensation assembly 200, preventing loss of light energy. The optical filter 103 is located between the light source 101 and the cooling sensation assembly 200. That is, the light source 101, the optical filter 103, and the cooling sensation assembly 200 are sequentially arranged along the light propagation direction. The optical filter 103 is used to filter out some of the harmful light emitted from the light source 101, reducing damage to the skin caused by light and improving safety during hair removal. Two electrodes 104 are connected to either side of the light source 101 and electrically connected to the circuit board 600 for transmitting electrical signals.
[0073] Optionally, the light source 101 may be a lamp, and the color of the light emitted by the lamp is not limited, and may be colored light, synthetic light, etc., and the specific wavelength and frequency are determined according to the application. The type of the lamp is also not limited, and may be a semiconductor xenon lamp, a quartz lamp, a laser lamp, etc., and the type of photons may be IPL (Intense Pulse Light), DPL (Delicate Pulse Light), OPT (Optimal Pulse Technology), AOPT (Advanced Optimal Pulse Technology), BBL (BroadBand Light), etc., and the specific type is determined according to the desired effect.
[0074] Optionally, the reflector 102 may be a U-shaped reflector surrounding the light source 101, and the opening of the U-shaped reflector may be directed toward the cooling sensation assembly 200 to reflect light that does not enter the cooling sensation assembly 200 to the cooling sensation assembly 200. At the same time, the reflector 102 may also prevent heat generated by the light source 101 from dissipating to other components in the hair removal device. In this embodiment, the holder 500 includes a fixed holder 550 and a pipe 560, and a first receiving space 510 and a second receiving space 520 are provided inside the fixed holder 550. Here, the first accommodating space 510 is used to mount the hair removal assembly 100, and the second accommodating space 520 is used to mount the cooling sensation assembly 200. The first accommodating space 510 and the second accommodating space 520 are arranged adjacent to each other, thereby shortening the distance between the hair removal assembly 100 and the cooling sensation assembly 200 and reducing the optical path loss of the light emitted from the hair removal assembly 100, and the second accommodating space 520 is closer to the head 111 of the hair removal device shown in Figure 6 than the first accommodating space 510.
[0075] When the hair removal device is in operation, the light source 101 generates a large amount of heat, and the reflector 102 and the optical filter 103 are also irradiated with light, which leads to an increase in temperature, so it is necessary to dissipate heat from the light source 101, the reflector 102 and the optical filter 103.
[0076] In this embodiment, the holder 500 includes a fixed holder 550 and a pipe 560, one end of which is connected to one side of the fixed holder 550 and the other end of which extends toward the cooling drive assembly 400. An air outlet 540 communicating with the first accommodating space 510 is provided within the fixed holder 550, and an air inlet 530 communicating with the first accommodating space 510 is provided in the pipe 560, so that the air inlet 530, the first accommodating space 510, and the air outlet 540 are sequentially connected to each other.
[0077] The air inlet 530 communicates with the cooling drive assembly 400, and the air outlet 540 communicates with the air permeation holes 1211. The cooling drive assembly 400 draws in outside air through the air permeation holes 1211 and blows it out through the air outlet 540. After entering the first accommodating space 510 through the air outlet 540, the air absorbs heat from the light source 101, reflector 102, and optical filter 103 in the first accommodating space 510 and flows out through the air outlet 540 and the air permeation holes 1211 to the outside, dissipating the heat to the outside.
[0078] Optionally, a portion of each of the fixed holder 550 and the pipe 560 forms a first holder 501, and the remaining portion of each of the fixed holder and the pipe forms a second holder 502; in other embodiments, the fixed holder 550 may be integrally formed.
[0079] The first holder 501 and the second holder 502 can be connected together by snaps. The first holder 501 is adjacent to the first shell 121, and the second holder 502 is adjacent to the second shell 122. An air outlet 540 is provided in the first holder 501 and opposite the air permeation hole 1211 of the first shell 121, thereby accelerating the heat dissipation efficiency of the air outlet 540. The first accommodating space 510 is provided within the first holder 501 and the second holder 502, where the corresponding portions of the fixed holder 550 are engaged. The air inlet 530 is provided within the first holder 501 and the second holder 502, where the corresponding portions of the pipe 560 are engaged, and communicates with the first accommodating space 510 and the cooling drive assembly 400. An air conduction path may be provided within the holder 501 to facilitate guiding the airflow from the cooling drive assembly 400 into the first accommodating space 510.
[0080] Therefore, in this embodiment, the epilating assembly 100 dissipates heat through the cooling drive assembly 400, ensuring the safe use of the epilating device.
[0081] Furthermore, in this embodiment, the cooling sensation assembly 200 may include an optically transparent body 202 and a cooling member 201 .
[0082] The light-transmitting body 202 is used to be applied to the skin and is arranged opposite the light source 101, and the light-transmitting body 3 is a light-transmitting part, and the light emitted from the light source 101 enters the light-transmitting body 202 and is then emitted from the light-transmitting body 202 to the skin.
[0083] Optionally, the optically transparent body 202 may be made of a light-conducting crystal, such as sapphire, K9 glass, or crystal glass, and when made of sapphire, the optically transparent body 202 has excellent thermal conductivity.
[0084] Optionally, the optically transparent body 202 may be a cylindrical or rectangular body, and the surface of the optically transparent body 202 away from the light source 101 is used to apply to the skin.
[0085] The cooling member 201 is connected to the optically transparent body 202 and is used to absorb heat from the optically transparent body 202. When the optically transparent body 202 comes into contact with the skin, its temperature rises, so the cooling member 201 absorbs the heat from the optically transparent body 202 after the temperature of the optically transparent body 202 rises, thereby maintaining the optically transparent body 202 at a low temperature. As a result, even if the optically transparent body 202 is applied to the skin for a long period of time, the skin can be cooled and pain on the skin can be reduced.
[0086] Furthermore, the cooling member 201 may be a semiconductor cooling type cooling component, the heat absorption end of which is connected to the light transmitting body 202 and the other end of which dissipates heat.
[0087] In order to allow the heat dissipation end of the cooling member 201 to dissipate heat, in this embodiment, the heat dissipation base 300 is connected to the heat dissipation end of the cooling member 201 to absorb the heat of the cooling member 201 .
[0088] Specifically, the heat dissipation base 300 includes a heat dissipation plate 301 and heat dissipation fins 302. A first region 310 and a second region 311 are arranged side by side on one side of the heat dissipation plate 301, the hair removal assembly 100 is arranged in the first region 310, and the heat dissipation fins 302 are attached to the second region 311. The second region 311 is located on one side of the fixed holder 550 where the pipe 560 is connected, the heat dissipation fins 302 and the pipe 560 are arranged side by side on one side of the fixed holder, and the fixed holder 550 is arranged in the first region 310. The heat dissipation plate 301 is attached to the circuit board 600 and connected to the cooling assembly 200, and specifically, the cooling member 201 can be bonded to the heat dissipation plate 301 by thermally conductive silicone grease. The cooling assembly 200 can quickly conduct heat to the heat dissipation plate 301 through the thermally 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 continue to absorb heat from the cooling member 201.
[0089] Optionally, there are a plurality of heat dissipation fins 302, the plurality of heat dissipation fins 302 are parallel to each other, and the heat dissipation fins 302 can be attached to the heat dissipation plate 301 by welding.
[0090] Optionally, the surface of the heat dissipation fins 302 can be sprayed with thermally conductive paint, which can not only dissipate heat from the heat dissipation fins 302, but also prevent water vapor from affecting the heat dissipation fins 302, and is also resistant to corrosion and abrasion.
[0091] In this embodiment, the heat dissipation plate 301 may be a vapor chamber, in which the liquid working substance inside absorbs heat by evaporating and liquefying when heated, and then cools and dissipates heat, thereby maintaining the surface temperature of the vapor chamber constant through the cycle of evaporation and condensation. Therefore, a part of the surface of the heat dissipation plate 301 is connected to the cooling element 201, and another part is connected to the heat dissipation fins 302, and the heat generated in the cooling element 201 is dissipated through the heat dissipation plate 301 and the heat dissipation fins 302.
[0092] Optionally, a carbon-containing layer may be provided between the light-transmitting body 202 and the heat dissipation base 300, for example, on the surface of the heat dissipation plate 301 that is thermally coupled to the light-transmitting body 202. The carbon-containing layer has excellent thermal conductivity, which can accelerate the thermal conductivity of the heat dissipation plate 301 and improve the heat dissipation performance of the heat dissipation base 300.
[0093] Optionally, the carbon-containing layer is a graphene material, graphite powder, graphite sheets, or graphite films.
[0094] Optionally, the carbon-containing layer is applied by plating, spraying or laminating.
[0095] In order to improve the heat dissipation performance of the heat dissipation base 300, in this embodiment, the heat dissipation base 300 further communicates with the cooling drive assembly 400.
[0096] Specifically, the heat dissipation fins 302 of the heat dissipation base 300 are connected to the cooling drive assembly 400, and the cooling drive assembly 400 draws in outside air through the air permeation holes 1211 and drives the air to blow onto the heat dissipation fins 302, so that the air flows through the heat dissipation fins 302 and causes the heat dissipation fins 302 to dissipate heat.
[0097] In an exemplary embodiment, the heat dissipation fins 302 are arranged in a square shape and parallel to the airflow provided by the cooling drive assembly 400, thereby increasing the area of the heat dissipation fins 302 that comes into contact with the airflow and accelerating the heat dissipation efficiency of the heat dissipation fins 302.
[0098] The heat dissipation fins 302 are provided opposite the air passage holes 1211 on the first shell 121 , and the airflow passes through the heat dissipation fins 302 and then quickly flows out through the air passage holes 1211 .
[0099] Therefore, the cooling drive assembly 400 in this embodiment can drive the cooling medium to not only dissipate heat from the hair removal assembly 100, but also dissipate heat from the heat dissipation base 300. With improved safety performance, the irradiated skin can be cooled to a cool sensation, reducing the burning pain caused by the irradiated skin, and the cooling drive assembly 200 can reach a low temperature close to 0°C under the action of the heat dissipation base 300 and the cooling drive assembly 400, allowing the skin near the light outlet to approach the freezing point indefinitely, thereby reducing the burning pain of the skin and preventing damage to the skin due to short-term contact.
[0100] 7, 8 and 10, Fig. 10 is a schematic diagram showing a structure at the air outlet of the fan housing in the embodiment of Fig. 8. In this embodiment, the cooling drive assembly 400 may include a fan housing 401 and a fan 402. The fan housing 401 is provided on the side of the heat dissipation base 300 facing away from the cooling sensation assembly 200, and the fan 402 is housed within the fan housing 401.
[0101] One end of the intake of the fan 402 faces the air permeation hole 1211 on the first shell 121, and the fan 402 is driven to send outside air into the fan 402 from the air permeation hole 1211. The fan housing 401 is provided with an air outlet 410 for blowing out air, and one end of the air outlet of the fan 402 is connected to the air outlet 410. The fan 402 is driven to draw outside air into the fan 402 from the air permeation hole 1211 and then discharge the air from the air outlet 410.
[0102] Optionally, fan 402 may be a centrifugal fan, an axial flow fan, a mixed flow fan, or a cross flow fan.
[0103] Furthermore, the air outlet 410 includes a first air outlet 411 and a second air outlet 412, and the air from the air outlet 410 of the fan 402 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.
[0104] Optionally, the air outlets 410 may include a third air outlet or more air outlets, but are not limited thereto.
[0105] In this embodiment, the first air outlet 411 is connected to the air inlet 530 of the holder 500, and the fan 402 is driven to draw outside air into the fan 402 through the air permeation hole 1211, and the fan 402 is driven to draw airflow through the first air outlet 411 and the air inlet 530 into the first accommodating space 510, which removes heat from the light source 101, the reflector 102 and the optical filter 103 in the first accommodating space 510, and finally flows out to the outside through the air exhaust port 540 and the air permeation hole 1211, thereby realizing heat dissipation of the hair removal assembly 100.
[0106] 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 is driven to draw outside air into the fan 402 through the air permeation holes 1211. The fan 402 is driven to draw airflow from the second air outlet 412 into the heat dissipation fins 302 of the heat dissipation base 300, and the airflow passes through the heat dissipation fins 302 to remove heat therefrom and then exits through the air permeation holes 1211. When the temperature of the heat dissipation fins 302 decreases, the heat of the heat dissipation plate 301 is also reduced, so that the heat dissipation plate 301 can absorb the heat of the cooling assembly 200 and realize heat dissipation of the cooling assembly 200.
[0107] Optionally, the airflow rates at the first air outlet 411 and the second air outlet 412 are not limited and are set according to actual conditions. The airflow rates at the first air outlet 411 and the second air outlet 412 can be controlled by setting the sizes of the first air outlet 411 and the second air outlet 412. For example, in this embodiment, the air blowing area of the second air outlet 412 is larger than the air blowing area of the first air outlet 411, so that more air flows out from the second air outlet 412 and improves the heat dissipation efficiency of the heat dissipation plate 301.
[0108] From the above, the hair removal device of this embodiment uses the cooling drive assembly 400 to dissipate heat from the hair removal assembly 100, the cooling sensation assembly 200 and the heat dissipation base 300, and further realizes simultaneous heat dissipation from the hair removal assembly 100 and the cooling sensation assembly 200, thereby improving the heat dissipation performance of the hair removal device, increasing the safety factor of the hair removal device, and making the cooling sensation on the skin infinitely close to freezing point, reducing the burning pain on the skin, and preventing damage to the skin during hair removal.
[0109] 16 and 17 , the present application discloses an epilator, which includes a reflector 1, a light source 2, a first light-transmitting body 3, a heat-dissipating base 4, and a cooling member 5. The light source 2 is assembled in the reflector 1 and can emit light, and the reflector 1 can reflect the light. The first light-transmitting body 3 is provided on the light-emitting side of the reflector 1 and covers the light-emitting side of the reflector 1, forming a cavity together with the reflector 1 that can accommodate the light source 2. The reflector 1 is embedded in the heat-dissipating base 4, and the side of the heat-dissipating base 4 that contacts the reflector 1 is thermally coupled to the reflector 1. The cooling member 5 is attached to the heat-dissipating base 4, and the cooling side of the cooling member 5 is thermally coupled to the side of the heat-dissipating base 4 that contacts the cooling member 5. Here, the main body of the light source 2 can be suspended in the cavity, and the cooling member 5 is used to cool the cavity.
[0110] During operation of the epilator, the light source 2 emits a large amount of light within the reflector 1, and the heat generated by that light accumulates within the cavity, causing the temperature of the reflector 1 to rise as the heat concentrates within the cavity. One side of the heat dissipation base 4 is thermally coupled to the reflector 1, and the cooling element 5 is thermally coupled to the other side of the heat dissipation base 4. The thermal coupling can transfer heat through thermal conduction, thermal convection, thermal radiation, or any combination of the above three methods. That is, the heat dissipation base 4 can transfer heat from the reflector 1 to the outside while simultaneously dissipating heat within the cavity, thereby cooling the reflector 1 and the cavity, thereby improving the heat dissipation efficiency of the light source 2. Hanging the body of the light source 2 in the cavity also allows for more uniform heat dissipation from the light source 2, which is beneficial for extending the service life of the light source 2. Specifically, the heat generated when the light source 2 is operating is dissipated to the surroundings in the form of radiation, and the air medium is uniformly wrapped around the light source 2 and is in sufficient contact with the light source 2, so that the heat generated by the light source 2 is also uniformly dissipated. The heat is generated by the light source 2, passes through the cavity, and is transferred to the reflector 1 and the first optically transparent body 3, where it is dissipated.
[0111] Furthermore, the cooling element 5 can transfer the heat on the heat dissipation base 4 and achieve the purpose of rapid heat dissipation, further improving the heat dissipation effect of the epilator, while reducing the heat in the cavity from being radiated to other parts of the epilator, thereby reducing the burning sensation on the epilated skin during the process of using the epilator and improving the usability of the epilator.
[0112] Optionally, the epilator may further include a carbon-containing layer 91 provided on the reflector 1. For example, referring to FIG. 18 , the carbon-containing layer 91 may be provided on the side of the reflector 1 facing away from the light source 2. The light source 2 generates heat during use and concentrates the heat on the reflector 1. The carbon-containing layer 91 has excellent thermal conductivity, which accelerates the heat conduction rate of the reflector 1 on which it is provided, improves the heat dissipation performance of the reflector 1, and prevents damage to the epilator itself due to excessive heat, as well as irritation and damage to the user's skin.
[0113] Optionally, the carbon-containing layer is provided on the heat dissipation base 4. For example, as shown in FIG. 18, it is provided between the heat dissipation base 4 and the reflector 1 to promote the heat conduction rate between the heat dissipation base 4 and the reflector 1.
[0114] Optionally, the carbon-containing layer can also be provided on the side of the cooling member 5 facing the heat dissipation base 4 or on the exposed surface of the cooling member 5 to enhance the cooling effect of the cooling member 5, thereby achieving the purpose of instantly and quickly removing heat from the heat dissipation base 4 and quickly dissipating heat from the reflector 1.
[0115] Optionally, the carbon-containing layer may be a material such as graphene material, graphite powder, graphite sheet or graphite film, which may be provided by plating, spraying, laminating or the like where a carbon-containing layer as described herein is provided.
[0116] Optionally, the heat dissipation base 4 may be a ceramic base or an aluminum base, which is used to quickly dissipate heat from the reflector 1, thereby improving the heat dissipation effect of the reflector 1. For example, ceramic itself has stable physical properties such as corrosion resistance and small thermal expansion and cooling contraction, and has a fast heat absorption rate, so the ceramic base can quickly absorb heat and cool the reflector 1 and the cavity, thereby improving the heat dissipation effect of the epilator.
[0117] Furthermore, because ceramic is an insulator, it will not short-circuit when it comes into contact with the reflector 1. The ceramic base covers the outer surface of the reflector 1, reducing the risk of leakage at the reflector 1 of the epilator, improving the safety of the epilator. The main body of the light source 2 is suspended within the cavity, with a gap between it and the reflector 1, which is made of a conductor. After electricity is applied, a strong electric field is formed between the light source 2 and the reflector 1, exciting the light source 2 to emit light.
[0118] Here, a slot 41 is formed on one side of the ceramic base, and the slot 41 is elongated. Optionally, the reflector 1 may be a semicircular arc-shaped reflector, and the reflector 1 is embedded in the slot 41. The first light-transmitting body 3 may be an optical filter or a transparent glass carrier, and the first light-transmitting body 3 is fixed to the ceramic base. Heat generated by the light source 2 is confined within the cavity by the first light-transmitting body 3 and the reflector 1, reducing the possibility of the heat being radiated to other parts of the epilator. The slot 41 is formed in the ceramic base, and the reflector 1 is embedded in the slot 41, thereby increasing the contact area between the ceramic base and the reflector 1, further improving the heat absorption performance of the ceramic base for the reflector 1, and improving the heat dissipation effect of the reflector 1 and the cavity.
[0119] Optionally, the reflector 1 may be an elongated reflector.
[0120] 16 , optionally, the cooling member 5 may be a TEC cooling sheet or a cooling block, and the cooling member 5 is used to cool the heat dissipation base 4, thereby achieving the purpose of instantly and quickly removing the heat on the heat dissipation base 4 and quickly dissipating the heat of the reflector 1. In one example of the present application, the adopted cooling member 5 is a TEC cooling sheet, which is merely exemplary and not limiting.
[0121] Optionally, the heat dissipation base 4 may be elongated, and the TEC cooling sheet may also be elongated. The heat dissipation base 4 may have an attachment groove formed on the side of the heat dissipation base 4 away from the opening of the reflector 1. The TEC cooling sheet is placed in the attachment groove and is in sufficient contact with the heat dissipation base 4. The TEC cooling sheet can quickly transfer heat transferred from the cavity and the reflector 1 to the heat dissipation base 4 to cool the heat dissipation base 4. On the one hand, it can better protect the light source 2 during operation of the epilator, effectively reduce damage to the light source 2 caused by high temperatures, and extend the service life of the light source 2. On the other hand, it can lower the temperature of the outer surface of the epilator, making it more comfortable for the user to hold the epilator, and improving the performance of the epilator.
[0122] 16, 17 and 19, the epilator includes a holder 6, which cooperates with a heat dissipation base 4 to assemble the reflector 1 and the first light-transmitting body 3 together. The holder 6 has a window 61, which is square or rectangular, and the first light-transmitting body 3 is fixed to the holder 6 to cover the window 61. The heat dissipation base 4 and the holder 6 are detachably connected to facilitate assembly and disassembly of the epilator. The reflector 1 and the first light-transmitting body 3 can be fixed together by the holder 6 and the heat dissipation base 4, which makes the internal structure of the epilator more compact and saves space inside the epilator, making the design more reasonable and facilitating use of the epilator.
[0123] Optionally, a first fastener 42 is integrally formed on both sides of the heat dissipation base 4, and a second fastener 62 is integrally formed on both sides of the holder 6, and the first fastener 42 and the second fastener 62 are provided correspondingly. When the heat dissipation base 4 and the holder 6 are connected, the first fastener 42 and the second fastener 62 are firmly engaged with each other, which further ensures that the heat dissipation base 4 and the holder 6 are connected securely, thereby improving the stability of the epilator when in use.
[0124] Optionally, the first fastener 42 may be a locking block or a cantilever hook, and the second fastener 62 may be a fixing hole. When the cantilever hook is embedded in the fixing hole, the fixing hole prevents the cantilever hook from easily coming off the fixing hole, and the first fastener 42 and the second fastener 62 can be securely connected, that is, the heat dissipation base 4 and the holder 6 can be fixed relative to each other, which effectively prevents the heat dissipation base 4 and the holder 6 from loosening or coming off and improves the stability of the entire epilator.
[0125] 16, 17 and 19, a second optically transparent body 7 is fixed to the holder 6, and the second optically transparent body 7 is square or rectangular, and the second optically transparent body 7 is embedded in the window 61. The second optically transparent body 7 is located on the side of the optical filter facing away from the light source 2, and has an incident surface 71 facing the light source 2 and an exit surface 72 facing away from the light source 2. Optionally, the second optically transparent body 7 may be a crystal, and the second optically transparent body 7 may be diamond, and the examples of the present application will be described taking a crystal as an example.
[0126] When the hair removal device is in operation, the light source 2 emits light, the reflector 1 reflects the light, and the light passes through the optical filter and is reflected by the crystal. The light enters from the incident surface 71, is reflected by the crystal body, and exits from the exit surface 72. The light exiting from the exit surface 72 is irradiated onto the area of the skin to be removed, thereby easily removing hair on the skin.
[0127] Optionally, the number of TEC cooling sheets may be two or three. For example, the number of TEC cooling sheets may be two, and the two TEC cooling sheets are spaced apart, with one TEC cooling sheet fixed to the heat dissipation base 4 and the other attached to the holder 6. The holder 6 has an attachment hole that communicates with the window 61. When the second optically transparent body 7 is embedded in the window 61, the TEC cooling sheet is embedded in the attachment hole and abuts against the second optically transparent body 7. Cooling the second optically transparent body 7 with the TEC cooling sheet allows the second optically transparent body 7 to rapidly dissipate heat, effectively reducing the temperature of the second optically transparent body 7 and minimizing the heat generation on the emission surface 72. This allows the epilator to safely contact the skin portion to be epilated and improves comfort when using the epilator.
[0128] Optionally, for example, the number of TEC cooling sheets may be three, of which one TEC cooling sheet is fixed to the heat dissipation base 4 and the remaining two TEC cooling sheets are respectively embedded in holders, and the two TEC cooling sheets are respectively located on both sides of the second light-transmitting body 7, which may be the upper and lower sides or the left and right sides of the second light-transmitting body 7 facing the light emission direction. 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 and allow the second light-transmitting body 7 to dissipate heat quickly, further achieving the cooling purpose and improving the heat dissipation effect of the epilator.
[0129] 20, optionally, the structures and relative positions of the light source 2, reflector 1, and second light-transmitting body 7 satisfy the condition that the light emission uniformity of the emission surface 72 is 90% or more, or the light spot on the emission surface 72 occupies at least 95% of the emission surface 72. By ensuring that the light emission uniformity of the emission surface 72 is 90% or more, the hair removal effect of the epilator can be improved and hair on the target skin area can be uniformly removed. Similarly, by ensuring that the light spot on the emission surface 72 occupies at least 95% of the emission surface 72, hair on the target skin area can be uniformly removed and the light utilization rate can be improved.
[0130] For epilators with low light emission uniformity or a small ratio of light spots on the emission surface 72 to the emission surface 72, the same area may need to be irradiated multiple times to achieve uniform hair removal. Otherwise, hair removal will be ununiform and undesirable from an aesthetic standpoint. In the embodiment of the present application, the structure and relative positional relationship of the light source 2, reflector 1, and second light-transmitting body 7 satisfy the conditions that the light emission uniformity of the emission surface 72 is 90% or more, or that the light spots on the emission surface 72 occupy at least 95% of the emission surface 72, so the epilator does not need to irradiate the same area multiple times. If the quality of the light source 2 and the power of the epilator are sufficient and meet human health requirements, the epilator can achieve efficient and uniform hair removal with just one irradiation.
[0131] Optionally, the centers of the reflector 1, the light source 2 and the second light-transmitting body 7 may be on a straight line, and by adjusting the distance between the three on the straight line, it is possible to make the light emission uniformity of the emission surface 72 90% or more, or to make the light spot on the emission surface 72 occupy at least 95% of the emission surface 72. Optionally, the structures of the three can be adjusted to make the epilator meet the above conditions.
[0132] Optionally, the center of the light source 2 is located between the focal point of the reflector 1 (labeled as 1a in the figure) and the bottom of the reflector 1, the incident surface 71 of the second optically transparent body 7 is located between the exit surface 72 and the focal point of the reflector 1, and the focusing position of the light reflected from the reflector 1 is between the exit surface 72 of the second optically transparent body 7 and the focal point of the reflector 1. By limiting the positions of the light source 2, the reflector 1, and the second optically transparent body 7, the light exit uniformity of the exit surface 72 can be made to be 90% or more, or the light spot on the exit surface 72 can occupy at least 95% of the exit surface 72, so that the light emitted by the light source 2 can be sufficiently reflected by the reflector 1 to the optically transparent body 7, thereby improving the light exit uniformity of the second optically transparent body 7.
[0133] 19, the reflector 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 reflector 1. The second reflective area 12 is a planar area extending outward from both ends of the arc-shaped area, and the planar area is in contact with the arc-shaped area. Optionally, the light source 2 may be a rod-shaped lamp, which emits light. The arc-shaped area of the reflector 1 can effectively reflect the light to the second light-transmitting body 7. At the same time, the planar area of the reflector 1 can also reflect the light to the second light-transmitting body 7. The sufficient reflection of the light by the arc-shaped area and the planar area increases the light emission rate and improves the light utilization rate.
[0134] For example, when the epilator is in operation, the light source 2 emits light, and the first reflective area 11 and the second reflective area 12 of the reflector 1 sufficiently reflect the light to the second light-transmitting body 7, so that the light enters the incident surface of the second light-transmitting body 7 and then exits from the exit surface of the second light-transmitting body 7, thereby making the light emission uniformity of the exit surface 72 more than 90%, or making the light spot on the exit surface 72 occupy at least 95% of the exit surface 72, thereby improving the light emission uniformity of the epilator and improving the use effect of the epilator.
[0135] Optionally, the angle between the planar region and the reference line is 5 to 20 degrees, and the reference line is a line connecting the center of the light source 2 and the center of the second optically transparent body 7. For example, the angle between the planar region and the reference line may be 5 degrees or 8 degrees, or even 15 degrees. By limiting the angle between the planar region and the reference line so that light can be sufficiently reflected by the second optically transparent body 7, on the one hand, light waste can be reduced and usage costs can be reduced, and on the other hand, the light emission uniformity of the second optically transparent body 7 can be improved.
[0136] For example, in this range, the focal length is close, and under the condition of satisfying the light emission uniformity and light utilization rate, the second light-transmitting body 7 can also be made closer to the light source 2, thereby making the structure of the hair removal device more compact and saving materials in processing.
[0137] 16, 17 and 19, the epilator includes side reflecting members 13 that are provided at both ends of the reflector 1 in the longitudinal direction and that reflect light leaking from both ends of the reflector 1 toward the light exit side of the reflector 1. The side reflecting members 13 sufficiently reflect the light emitted by the light source 2, which makes it easy to increase the light utilization rate, and therefore the epilator can effectively perform hair removal, and the side reflecting members 13 make it easy to attach the light source 2, improving attachment efficiency.
[0138] Optionally, the side reflective member 13 is integrally molded with the reflector 1, which reduces the difficulty of installation in terms of processing. Furthermore, the integral molding of the side reflective member 13 and the reflector 1 makes it strong and firm, increases the stability of the connection between the side reflective member 13 and the reflector 1, and extends the service life of the reflector 1.
[0139] Optionally, the light source 2 is a rod-shaped lamp, and the side reflecting members 13 located on both sides of the reflector 1 are each provided with a through-hole 131, and the end of the lamp passes through the through-hole 131. A fixing member 8 is connected to each end of the lamp for movably fixing the light source 2 to the reflector 1. For example, the fixing member 8 may be a soft sleeve made of silicone or a rubber sleeve. The fixing member 8 is cylindrical and has an accommodating groove 81, and both ends of the lamp are embedded in the accommodating groove 81. The fixing member 8 has a mounting hole 82 formed along its axis, which communicates with the accommodating groove 81. Mounting posts 21 extend from both ends of the lamp, and the mounting posts 21 pass through the mounting holes 82. The fixing members 8 are provided on the outside of the reflector 1.
[0140] Optionally, support blocks 43 are integrally formed on both ends of the heat dissipation base 4, and the support blocks 43 have notches that can accommodate both ends of the light source 2 and the fixing member 8. When the heat dissipation base 4 and the holder 6 are engaged, the fixing member 8 is fixed by the holder 6 and the support blocks 43, and the lamp is fixed to the reflector 1. The fixing member 8 itself has elasticity, and when the fixing member 8 is pressed during the process of being fixed by the holder 6 and the support blocks 43, the fixing member 8 can appropriately change its shape to adapt to the shape of the notches, and at the same time, damage to the lamp can be reduced and the pressing of the lamp can be minimized.
[0141] This embodiment discloses an epilator with the function of enhancing the heat dissipation effect of the epilator. The light source 2 is assembled within the reflector 1 and can emit light. The reflector 1 reflects the light, further enabling the light emission of the epilator, thereby easily removing hair from the skin and achieving the purpose of hair removal. The first light-transmitting body 3 and the reflector 1 form a cavity that accommodates the light source 2. The body of the light source 2 is suspended within the cavity, and both sides of the heat dissipation base 4 are thermally coupled to the reflector 1 and the cooling element 5, respectively, so that heat within the cavity can be rapidly transferred from the cavity to the heat dissipation base 4 and the cooling element 5, further cooling the cavity. This improves the heat dissipation effect of the epilator, allows the light source 2 to dissipate heat evenly, and extends the service life of the light source 2. Furthermore, the excellent heat dissipation performance improves the comfort of using the epilator.
[0142] 26 and 27, in another embodiment of the epilator according to the present application, an elastic sealing ring 16 is provided between the first light-transmitting body 3 and the second light-transmitting body 7, the elastic sealing ring 16 is annular, and both the first light-transmitting body 3 and the second light-transmitting body 7 are fitted together to seal with the elastic sealing ring 16, so that condensation does not occur between the second light-transmitting body 7 and the first light-transmitting body 3, and some dirt cannot enter the connection point between the second light-transmitting body 7 and the first light-transmitting body 3, and the elastic sealing ring 16 is preferably annular.
[0143] Of course, if the epilator is accidentally dropped to the ground, a rigid-body collision may occur between the second light-transmitting body 7 and the ground, and in the conventional second light-transmitting body 7, the impact force may be transmitted to the first light-transmitting body 3, further damaging the first light-transmitting body 3, the reflector 1, and the light source 2. In the epilator of this embodiment, the impact force when the second light-transmitting body 7 collides can be counteracted by the elastic seal ring 16, and when pressed by an external force, the elastic seal ring 16 causes elastic deformation due to its own elasticity, thereby reducing or counteracting the impact between the first light-transmitting body 3 and the second light-transmitting body 7, thereby reducing the possibility that the first light-transmitting body 3, the reflector 1, and the light source 2 will be damaged by such impacts, and further improving the collision avoidance performance of the epilator.
[0144] Further, referring to Figures 28 to 30, the elastic sealing ring 16 is provided with an inner ring 161 for passing light, and the light filtered by the first light-transmitting body 3 is guided to the second light-transmitting body 7 through the inner ring 161 so that it can be irradiated onto human skin.
[0145] In this embodiment, the first light-transmitting body 3 and the second light-transmitting body 7 are both directly fixed to the holder 6 and cannot move relative to the holder 6. This effectively prevents a bone or a sharp object from hitting the second light-transmitting body 7 during use, causing the second light-transmitting body 7 to retreat relative to the holder 6, thereby preventing irreversible deformation of the first light-transmitting body 3 or the hair removal assembly 100. Furthermore, even if the elastic sealing ring 16 is pressed multiple times and irreversible deformation occurs, it is possible to avoid wasting light energy due to the impact on the light-guiding effect of the hair removal device.
[0146] The elastic sealing ring 16 further has an attachment groove 162 communicating with the inner ring 161, the attachment groove 162 being located on the side of the elastic sealing ring 16 away from the hair removal assembly 100, the inner ring 161 extending through from the bottom wall of the attachment groove 162 towards the side of the first light-transmitting body 3, and the second light-transmitting body 7 being partially attached within the attachment groove 162, thereby improving the sealing performance between the second light-transmitting body 7 and the elastic sealing ring 16 and fixing the elastic sealing ring 16 to the second light-transmitting body 7 to achieve a fixed connection between the two.
[0147] In a preferred embodiment, the elastic sealing ring 16 includes an outer ring 163 and a protrusion 164 protruding from one side of the outer ring 163, the protrusion 164 abutting the first light-transmitting body 3, a mounting groove 162 is provided on the side of the outer ring 163 away from the protrusion 164, the inner ring 161 extends from the bottom wall of the mounting groove 162 to one side of the protrusion 164, and both the outer ring 163 and the protrusion 164 form a completely closed loop structure, and light within the inner ring 161 can only be transmitted through from the second light-transmitting body 7.
[0148] In a preferred embodiment, the cross section of the protrusion 164 is a transverse triangular structure, and the contact area of the protrusion 164 with the first optically transparent body 3 is smaller than the contact area of the protrusion 164 with the outer ring 163. Therefore, when the elastic sealing ring 16 is installed, the end of the protrusion 164 away from the outer ring 163 may be partially warped when pressed. Because the elastic sealing ring 16 is elastic, the warped portion of the elastic sealing ring 16 can firmly abut against the first optically transparent body 3. This means that even if the gap between the second optically transparent body 7 and the first optically transparent body 3 changes slightly, the warped portion of the elastic sealing ring 16 can adapt to this gap change. Therefore, a tight or interference fit is always maintained between the elastic sealing ring 16 and the second optically transparent body 7 and between the elastic sealing ring 16 and the first optically transparent body 3, resulting in better sealing. Of course, in other embodiments, the cross section of the protrusion 164 may be a trapezoidal structure.
[0149] In this embodiment, the elastic sealing ring 16 is an annular body made of a material that is laser-resistant and resistant to high and low temperatures, thereby preventing the elastic sealing ring 16 from being deformed by high or low temperatures or laser irradiation during use, and extending the service life of the elastic sealing ring 16.
[0150] Referring to Figure 21, Figure 21 is a schematic diagram showing the structure of another embodiment of the present application. Here, the hair removal device includes a head 111 and a handle 112 connected to the head 111. The head 111 is provided with a cooling unit 1111 for contact with the skin. The cooling unit 1111 emits light to irradiate hair follicles on the user's skin, allowing the light to penetrate the skin and irradiate the hair follicles to remove hair, while also rapidly lowering the temperature, reducing the burning sensation caused by the light on the skin and preventing the user from feeling uncomfortable during use. In some embodiments, the cooling unit 1111 can also emit light for skin care, thereby allowing the hair removal device to have both hair removal and skin care functions.
[0151] Optionally, the grip portion 112 may include a hollow shell (not numbered in the figures), with air permeable holes 1211 provided on the surface of the shell, which communicate the interior of the shell with the outside world, allowing the hair removal device to exchange air with the outside world through the air permeable holes 1211 and lower the temperature inside. The shell further includes a port 1212, which can be used to connect to an external power source and charge the hair removal device. Here, the location of the port 1212 on the shell is not limited.
[0152] 21 and 22, Fig. 22 is a schematic diagram showing an exploded structure of another embodiment of the present application, where the arrows shown in Fig. 22 represent the flow direction of airflow in the hair removal device under the driving of the cooling driving assembly, the straight lines represent the cold airflow, and the waves represent the hot airflow. Specifically, the hair removal device may include a shell, a light cover 113 provided at the opening of the shell, a hair removal mechanism 14 housed inside the shell, and a bottom cover 15.
[0153] In this embodiment, the shell may include a first shell 121 and a second shell 122, which are connected to each other in an engaging manner to form a cavity with openings at both ends, the hair removal mechanism 14 is housed in the cavity, and the light cover 113 and the bottom cover 15 are respectively provided to cover the two openings and are used to seal the openings after the first shell 121 and the second shell 122 are connected to form the cavity.
[0154] Optionally, the first shell 121, the second shell 122, the light cover 113 and the bottom cover 15 may be connected by snaps, or may be connected by screws or adhesive.
[0155] The epilation mechanism 14 includes an epilation assembly 100 , a cooling sensation assembly 200 , a heat dissipation base 300 and a cooling drive assembly 400 .
[0156] The cooling sensation assembly 200 is provided on the side close to the light cover 113, and the light cover 113 is provided with a through-hole (not provided with a reference number), and a part of the cooling sensation assembly 200 is exposed to the outside world from the inside of the shell through the through-hole of the light cover 113 and comes into direct contact with the skin. As can be understood, a part of the cooling sensation assembly 200 and the light cover 113 form the head 111 of the hair removal device.
[0157] The hair removal assembly 100 is provided on the side of the cooling sensation assembly 200 away from the light cover 113 and is used to emit light to the cooling sensation assembly 200. The light may be visible light such as red light, green light, or yellow light. The light is incident on the cooling sensation assembly 200 and passes through the cooling sensation assembly 200 to enter the hair follicles under the skin, thereby achieving hair removal.
[0158] The heat dissipation base 300 is provided on one side of the cooling sensation assembly 200 and is connected to the cooling sensation assembly 200. When the cooling sensation assembly 200 is placed against the skin, it absorbs heat from the skin, lowering the skin temperature and reducing the burning sensation. However, if the cooling sensation assembly 200 is used for a long time, its temperature will rise and its cooling effect will decrease. The heat dissipation base 300 absorbs the heat from the cooling sensation assembly 200, maintaining the cooling sensation assembly 200 in a low-temperature working environment and ensuring the cooling effect of the cooling sensation assembly 200 on the skin. Therefore, the hair removal device of this embodiment can maintain a low temperature even when used continuously, without causing pain to the user.
[0159] The cooling drive assembly 400 is provided on the side of the heat dissipation base 300 where at least a portion of the heat dissipation base 300 faces away from the epilation assembly 100 , and is used to dissipate heat from the epilation assembly 100 and the heat dissipation base 300 .
[0160] In this embodiment, the cooling drive assembly 400 draws in the external cooling medium and introduces it into the inside of the hair removal device through the air permeation holes 1211, and the cooling medium passes through the hair removal assembly 100 and the heat dissipation base 300 to carry away heat, and then flows out through the air permeation holes 1211.
[0161] Optionally, the external cooling medium may be air, and the cooling drive assembly 400 draws in the air and blows it onto the epilation assembly 100 and the heat dissipation base 300, and the heat of the epilation assembly 100 and the heat dissipation base 300 is carried away by the airflow.
[0162] In this embodiment, the air permeation holes 1211 are provided in the first shell 121, and at least a portion of the cooling drive assembly 400 faces the air permeation holes 1211, so that the cooling drive assembly 400 can better absorb the external cooling medium through the air permeation holes 1211 and improve heat dissipation efficiency. In other embodiments, the air permeation holes 1211 may be provided in the second shell 122.
[0163] 22 and 23, FIG. 23 is a schematic diagram showing an exploded structure of the embodiment of FIG. 22, where the arrows shown in FIG. 23 indicate the direction of air coming out of the fan.
[0164] In this embodiment, the hair removal device further includes a holder 500, a circuit board 600, a processor 700, and a capacitor 800, wherein the hair removal assembly 100 and the cooling sensation assembly 200 are mounted in the holder 500, and the cooling drive assembly 400 is provided adjacent to the holder 500. The hair removal assembly 100, the cooling sensation assembly 200, and the cooling drive assembly 400 are mounted on the circuit board 600 and electrically connected to the circuit board 600.
[0165] The processor 700 and the capacitor 800 are electrically connected to and mounted on the circuit board 600. When connected to an external power source, the external power source can charge the capacitor 800 so that the capacitor 800 can power the hair removal device, and the capacitor 800 can store power when connected to an external power source, allowing the hair removal device to be used even when not connected to an external power source. The processor 700 sends control commands to the hair removal assembly 100, the cooling sensation application assembly 200, and the cooling drive assembly 400 to control the operation of the hair removal device, such as controlling the switches of the hair removal device, thermal protection, power regulation, etc.
[0166] In this embodiment, the circuit board 600 may be fixed in the second shell 122, and the circuit board 600 may be selected as a PCBA circuit board.
[0167] In related art, the heat inside the hair removal device body often increases during use, and the internal circuits and components of the hair removal device are prone to explosion, burning, short circuit, etc. in a high-temperature environment. In this embodiment, the cooling drive assembly 400 can dissipate heat from the hair removal assembly 100 and the heat dissipation base 300, and the heat dissipation base 300 can dissipate heat from the cooling sensation assembly 200, so that the cooling sensation assembly 200 can ice the skin to increase skin comfort and prevent problems such as explosion, burning, short circuit, etc. caused by excessively high temperatures.
[0168] Specifically, the hair removal assembly 100 may include a light source 101 , a reflector 102 , a light filter 103 and two electrodes 104 .
[0169] The light source 101, the reflector 102 and the optical filter 103 are mounted in the holder 500, i.e., mounting locations for the light source 101, the reflector 102 and the optical filter 103 are provided in the holder 500, and the light source 101, the reflector 102 and the optical filter 103 are engaged into the mounting locations of the holder 500.
[0170] Here, the light source 101 is disposed opposite the cooling sensation assembly 200, and light emitted from the light source 101 can be directly incident on the cooling sensation assembly 200. The reflector 102 is disposed on the side of the light source 101 away from the cooling sensation assembly 200 and reflects the light from the light source 101 to the cooling sensation assembly 200, preventing loss of light energy. The optical filter 103 is located between the light source 101 and the cooling sensation assembly 200. That is, the light source 101, the optical filter 103, and the cooling sensation assembly 200 are sequentially arranged along the light propagation direction. The optical filter 103 is used to filter out some of the harmful light emitted from the light source 101, reducing damage to the skin caused by light and improving safety during hair removal. Two electrodes 104 are connected to either side of the light source 101 and electrically connected to the circuit board 600 for transmitting electrical signals.
[0171] Optionally, the light source 101 may be a lamp, and the color of the light emitted by the lamp is not limited, and may be colored light, synthetic light, etc., and the specific wavelength and frequency are determined according to the application. The type of the lamp is also not limited, and may be a semiconductor xenon lamp, a quartz lamp, a laser lamp, etc., and the type of photons may be IPL (Intense Pulse Light), DPL (Delicate Pulse Light), OPT (Optimal Pulse Technology), AOPT (Advanced Optimal Pulse Technology), BBL (BroadBand Light), etc., and the specific type is determined according to the desired effect.
[0172] Optionally, the reflector 102 may be a U-shaped reflector surrounding the light source 101, and the opening of the U-shaped reflector may be directed toward the cooling sensation assembly 200 to reflect light that does not enter the cooling sensation assembly 200 to the cooling sensation assembly 200. At the same time, the reflector 102 may also prevent heat generated by the light source 101 from dissipating to other components in the hair removal device. In this embodiment, the holder 500 includes a fixed holder 550 and a pipe 560, and a first receiving space 510 and a second receiving space 520 are provided inside the fixed holder 550. Here, the first accommodating space 510 is used to mount the hair removal assembly 100, and the second accommodating space 520 is used to mount the cooling sensation assembly 200. The first accommodating space 510 and the second accommodating space 520 are arranged adjacent to each other, thereby shortening the distance between the hair removal assembly 100 and the cooling sensation assembly 200 and reducing the optical path loss of the light emitted from the hair removal assembly 100, and the second accommodating space 520 is closer to the head 111 of the hair removal device shown in Figure 21 than the first accommodating space 510.
[0173] When the hair removal device is in operation, the light source 101 generates a large amount of heat, and the reflector 102 and the optical filter 103 are also irradiated with light, which leads to an increase in temperature, so it is necessary to dissipate heat from the light source 101, the reflector 102 and the optical filter 103.
[0174] In this embodiment, the holder 500 includes a fixed holder 550 and a pipe 560, one end of which is connected to one side of the fixed holder 550 and the other end of which extends toward the cooling drive assembly 400. An air outlet 540 communicating with the first accommodating space 510 is provided within the fixed holder 550, and an air inlet 530 communicating with the first accommodating space 510 is provided in the pipe 560, so that the air inlet 530, the first accommodating space 510, and the air outlet 540 are sequentially connected to each other.
[0175] The air inlet 530 communicates with the cooling drive assembly 400, and the air outlet 540 communicates with the air permeation holes 1211. The cooling drive assembly 400 draws in outside air through the air permeation holes 1211 and blows it out through the air outlet 540. After entering the first accommodating space 510 through the air outlet 540, the air absorbs heat from the light source 101, reflector 102, and optical filter 103 in the first accommodating space 510 and flows out through the air outlet 540 and the air permeation holes 1211 to the outside, dissipating the heat to the outside.
[0176] Optionally, a portion of each of the fixed holder 550 and the pipe 560 forms a first holder 501, and the remaining portion of each of the fixed holder and the pipe forms a second holder 502; in other embodiments, the fixed holder 550 may be integrally formed.
[0177] The first holder 501 and the second holder 502 can be connected together by snaps. The first holder 501 is adjacent to the first shell 121, and the second holder 502 is adjacent to the second shell 122. An air outlet 540 is provided in the first holder 501 and opposite the air permeation hole 1211 of the first shell 121, thereby accelerating the heat dissipation efficiency of the air outlet 540. The first accommodating space 510 is provided within the first holder 501 and the second holder 502, where the corresponding portions of the fixed holder 550 are engaged. The air inlet 530 is provided within the first holder 501 and the second holder 502, where the corresponding portions of the pipe 560 are engaged, and communicates with the first accommodating space 510 and the cooling drive assembly 400. An air conduction path may be provided within the holder 501 to facilitate guiding the airflow from the cooling drive assembly 400 into the first accommodating space 510.
[0178] Therefore, in this embodiment, the epilating assembly 100 dissipates heat through the cooling drive assembly 400, ensuring the safe use of the epilating device.
[0179] Furthermore, in this embodiment, the cooling sensation assembly 200 may include a second optically transparent body 201 and a cooling member 202 .
[0180] The second light-transmitting body 201 is used to be applied to the skin and is arranged opposite the light source 101. The second light-transmitting body 201 is a light-transmitting part, and the light emitted from the light source 101 enters the second light-transmitting body 201 and is then emitted from the second light-transmitting body 201 to the skin.
[0181] Optionally, the second optically transparent body 201 may be made of a light-conducting crystal, such as sapphire, K9 glass, or crystal glass, and when made of sapphire, the second optically transparent body 201 has excellent thermal conductivity.
[0182] Optionally, the second optically transparent body 201 may be a cylindrical or rectangular body, and the surface of the second optically transparent body 201 away from the light source 101 is used to apply to the skin.
[0183] The cooling member 202 is connected to the second optically transparent body 201 and is used to absorb heat from the second optically transparent body 201. When the second optically transparent body 201 comes into contact with the skin, its temperature rises, and the cooling member 202 absorbs the heat from the second optically transparent body 201 after the temperature of the second optically transparent body 201 rises, thereby maintaining the second optically transparent body 201 at a low temperature. As a result, even if the second optically transparent body 201 is applied to the skin for a long period of time, the skin can be cooled and pain on the skin can be reduced.
[0184] Furthermore, the cooling member 202 may be a semiconductor cooling type cooling component, the heat absorption end of which is connected to the second light transmitting body 201 and the other end of which dissipates heat.
[0185] In order to allow the heat dissipation end of the cooling member 202 to dissipate heat, in this embodiment, the heat dissipation base 300 is connected to the heat dissipation end of the cooling member 202 to absorb the heat of the cooling member 202 .
[0186] Specifically, the heat dissipation base 300 includes a heat dissipation plate 301 and heat dissipation fins 302. A first region 310 and a second region 311 are arranged side by side on one side of the heat dissipation plate 301, the hair removal assembly 100 is arranged in the first region 310, and the heat dissipation fins 302 are attached to the second region 311. The second region 311 is located on one side of the fixed holder 550 where the pipe 560 is connected, the heat dissipation fins 302 and the pipe 560 are arranged side by side on one side of the fixed holder, and the fixed holder 550 is arranged in the first region 310. The heat dissipation plate 301 is attached to the circuit board 600 and connected to the cooling assembly 200, and specifically, the cooling member 5 can be bonded to the heat dissipation plate 301 with thermally conductive silicone grease. The cooling assembly 200 can quickly conduct heat to the heat dissipation plate 301 through the thermally 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 continue to absorb heat from the cooling member 202.
[0187] Optionally, there are a plurality of heat dissipation fins 302, the plurality of heat dissipation fins 302 are parallel to each other, and the heat dissipation fins 302 can be attached to the heat dissipation plate 301 by welding.
[0188] Optionally, a thermally conductive paint can be sprayed onto the surface of the heat dissipation fins 302, which can not only dissipate heat from the heat dissipation fins 302, but also prevent water vapor from affecting the heat dissipation fins 302, and is also resistant to corrosion and abrasion.
[0189] In this embodiment, the heat dissipation plate 301 may be a vapor chamber, in which the liquid working substance inside absorbs heat by evaporating and liquefying after being cooled and releasing heat, and the surface temperature of the vapor chamber can be maintained constant through the cycle of evaporation and condensation. Therefore, a part of the surface of the heat dissipation plate 301 is connected to the cooling element 5, and another part is connected to the heat dissipation fins 302, and the heat generated in the cooling element 202 is dissipated through the heat dissipation plate 301 and the heat dissipation fins 302.
[0190] Optionally, referring to FIG. 24 , a carbon-containing layer 92 may be provided between the second light-transmitting body 201 and the heat dissipation base 300, for example, on the surface of the heat dissipation plate 301 that is thermally coupled to the second light-transmitting body 201. The carbon-containing layer 92 has excellent thermal conductivity, which can accelerate the thermal conductivity of the heat dissipation plate 301 and improve the heat dissipation performance of the heat dissipation base 300.
[0191] Optionally, the carbon-containing layer is a graphene material, graphite powder, graphite sheets, or graphite films.
[0192] Optionally, the carbon-containing layer is applied by plating, spraying or laminating.
[0193] In order to improve the heat dissipation performance of the heat dissipation base 300, in this embodiment, the heat dissipation base 300 further communicates with the cooling drive assembly 400.
[0194] Specifically, the heat dissipation fins 302 of the heat dissipation base 300 are connected to the cooling drive assembly 400, and the cooling drive assembly 400 draws in outside air through the air permeation holes 1211 and drives the air to blow onto the heat dissipation fins 302, so that the air flows through the heat dissipation fins 302 and causes the heat dissipation fins 302 to dissipate heat.
[0195] In an exemplary embodiment, the heat dissipation fins 302 are arranged in a square shape and parallel to the airflow provided by the cooling drive assembly 400, thereby increasing the area of the heat dissipation fins 302 that comes into contact with the airflow and accelerating the heat dissipation efficiency of the heat dissipation fins 302.
[0196] The heat dissipation fins 302 are provided opposite the air passage holes 1211 on the first shell 121 , and the airflow passes through the heat dissipation fins 302 and then quickly flows out through the air passage holes 1211 .
[0197] Therefore, the cooling drive assembly 400 in this embodiment can drive the cooling medium to not only dissipate heat from the hair removal assembly 100, but also dissipate heat from the heat dissipation base 300. With improved safety performance, the irradiated skin can be cooled to a cool sensation, reducing the burning pain caused by the irradiated skin, and the cooling drive assembly 200 can reach a low temperature close to 0°C under the action of the heat dissipation base 300 and the cooling drive assembly 400, allowing the skin near the light outlet to approach the freezing point indefinitely, thereby reducing the burning pain of the skin and preventing damage to the skin due to short-term contact.
[0198] 22, 23, and 25, Fig. 25 is a schematic diagram showing a structure at the air outlet of the fan housing in the embodiment of Fig. 23. In this embodiment, the cooling drive assembly 400 may include a fan housing 401 and a fan 402. The fan housing 401 is provided on the side of the heat dissipation base 300 facing away from the cooling sensation assembly 200, and the fan 402 is housed within the fan housing 401.
[0199] One end of the intake of the fan 402 faces the air permeation hole 1211 on the first shell 121, and the fan 402 is driven to send outside air into the fan 402 from the air permeation hole 1211. The fan housing 401 is provided with an air outlet 410 for blowing out air, and one end of the air outlet of the fan 402 is connected to the air outlet 410. The fan 402 is driven to draw outside air into the fan 402 from the air permeation hole 1211 and then discharge the air from the air outlet 410.
[0200] Optionally, fan 402 may be a centrifugal fan, an axial flow fan, a mixed flow fan, or a cross flow fan.
[0201] Furthermore, the air outlet 410 includes a first air outlet 411 and a second air outlet 412, and the air from the air outlet 410 of the fan 402 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.
[0202] Optionally, the air outlets 410 may include a third air outlet or more air outlets, but are not limited thereto.
[0203] In this embodiment, the first air outlet 411 is connected to the air inlet 530 of the holder 500, and the fan 402 is driven to draw outside air into the fan 402 through the air permeation hole 1211, and the fan 402 is driven to draw airflow through the first air outlet 411 and the air inlet 530 into the first accommodating space 510, which removes heat from the light source 101, the reflector 102 and the optical filter 103 in the first accommodating space 510, and finally flows out to the outside through the air exhaust port 540 and the air permeation hole 1211, thereby realizing heat dissipation of the hair removal assembly 100.
[0204] 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 is driven to draw outside air into the fan 402 through the air permeation holes 1211. The fan 402 is driven to draw airflow from the second air outlet 412 into the heat dissipation fins 302 of the heat dissipation base 300, and the airflow passes through the heat dissipation fins 302 to remove heat therefrom and then exits through the air permeation holes 1211. When the temperature of the heat dissipation fins 302 decreases, the heat of the heat dissipation plate 301 is also reduced, so that the heat dissipation plate 301 can absorb the heat of the cooling assembly 200 and realize heat dissipation of the cooling assembly 200.
[0205] Optionally, the airflow rates at the first air outlet 411 and the second air outlet 412 are not limited and are set according to actual conditions. The airflow rates at the first air outlet 411 and the second air outlet 412 can be controlled by setting the sizes of the first air outlet 411 and the second air outlet 412. For example, in this embodiment, the air blowing area of the second air outlet 412 is larger than the air blowing area of the first air outlet 411, so that more air flows out from the second air outlet 412 and improves the heat dissipation efficiency of the heat dissipation plate 301.
[0206] From the above, the hair removal device of this embodiment uses the cooling drive assembly 400 to dissipate heat from the hair removal assembly 100, the cooling sensation assembly 200 and the heat dissipation base 300, and further realizes simultaneous heat dissipation from the hair removal assembly 100 and the cooling sensation assembly 200, thereby improving the heat dissipation performance of the hair removal device, increasing the safety factor of the hair removal device, and making the cooling sensation on the skin infinitely close to freezing point, reducing the burning pain on the skin, and preventing damage to the skin during hair removal.
[0207] Referring to Figure 31, the epilator includes a reflector 1 and a light source 2. The reflector 1 is a conductor that can generate a high electric field when energized. The light source 2 is assembled in the reflector 1 and is disposed opposite the reflector 1. The light source 2 is Rod-shaped The gas-pumped light source is a gas-pumped light source, which can emit light by being excited by the reflector 1 after the reflector 1 is energized, and the reflector 1 has a light-emitting side and can reflect light and emit it from the light-emitting side of the reflector 1. Here, the distance between the body of the light source 2 and the reflector 1 is greater than zero and not more than 0.3 mm. For example, in the actual installation of the light source 2, the distance between the body of the light source 2 and the reflector 1 may be 0.3 mm, or the distance between the body of the light source 2 and the reflector 1 may be 0.15 mm. Similarly, the distance between the light source 2 and the reflector 1 can be limited depending on the structure of the reflector 1 and the light source 2 itself so that the distance between the body of the light source 2 and the reflector 1 is kept within 0.3 mm.
[0208] When the hair removal device is in operation, the reflector 1 generates a high electric field inside it when it is energized, generating a high voltage in the reflector 1, which ionizes the gas in the light source 2, generating an arc and further discharging, thereby allowing the light source 2 to emit light. By limiting the distance between the light source 2 and the reflector 1, the voltage inside the reflector 1 can excite the light source 2 to emit light. Compared with the method of triggering the lamp to emit light via a trigger wire, the reflector 1 that triggers the lamp to emit light without a trigger wire not only improves the method of triggering the lamp to emit light and increases luminous efficiency, but also saves materials and reduces manufacturing costs.
[0209] Optionally, the reflector 1 may be semicircular and the light source 2 may be a rod-shaped lamp. The lamp is attached to the reflector 1 in a suspended manner, so that the lamp body and the inner wall of the reflector 1 form an excitation space. The voltage within the reflector 1 excites the lamp without a retrigger wire, ionizing the gas within the lamp and causing the lamp to emit light. The reflector 1 not only triggers the lamp to emit light with a high voltage, but also serves as a mounting carrier for the light source 2. This eliminates the need for trigger wires and other components to excite the lamp, saving materials and reducing manufacturing costs. At the same time, the number of components within the reflector 1 can be reduced, reducing spatial clutter and helping the light emitted by the light source 2 to be fully reflected by the reflector 1, thereby increasing the light emission rate.
[0210] Optionally, the reflector 1 may be rod-shaped.
[0211] 31 and 32, optionally, the epilator includes a heat-dissipating base 3, an elastic body 4, and a holder 5. The heat-dissipating base 3 is elongated, and the reflector 1 is attached to the heat-dissipating base 3, with the light-emitting side of the reflector 1 facing away from the heat-dissipating base 3. Here, the side of the heat-dissipating base 3 that contacts the reflector 1 is thermally coupled to the reflector 1. The elastic body 4 is fixed to an end of the light source 2 to movably fix the light source 2 to the reflector 1, and the elastic body 4 is located on both sides of the reflector 1 in the longitudinal direction. The holder 5 and the heat-dissipating base 3 are fixedly connected by engagement, and the elastic body 4 is located between the heat-dissipating base 3 and the holder 5, and the holder 5 is pressed against the elastic body 4 in a direction perpendicular to the longitudinal direction of the light source 2 to fix the light source 2 to the reflector 1 or the heat-dissipating base 3. Because the heat dissipation base 3 fixes the reflector 1 together with the holder 5, the light source 2 can be stably attached to the reflector 1, and the heat dissipation base 3 and the holder 5 ensure the stability of the entire epilator. Here, the elastic body 4 itself has excellent elasticity, and when the holder 5 presses the elastic body 4, the structure of the elastic body 4 itself is easily deformed. On the one hand, shaking is less likely to occur between the light source 2 and the reflector 1, and the light emission effect can be improved. On the other hand, the elastic body 4 can well relieve the pressure of the holder 5 on the end of the light source 2 and maintain flexible contact with the end of the light source 2, thus not only effectively reducing damage to the light source 2 but also contributing to extending the service life of the light source 2.
[0212] Optionally, referring to FIG. 33 , the epilator may further include a carbon-containing layer 91 provided on the reflector 1. For example, the carbon-containing layer 91 may be provided on the side of the reflector 1 facing away from the light source 2. The light source 2 generates heat during use and concentrates the heat on the reflector 1. The carbon-containing layer 91 has excellent thermal conductivity, which accelerates the heat conduction rate of the reflector 1 on which it is provided, improves the heat dissipation performance of the reflector 1, and prevents damage to the epilator itself due to excessive heat, as well as irritation and damage to the user's skin.
[0213] Optionally, referring to FIG. 33 , the carbon-containing layer 91 is provided on the heat dissipation base 3. For example, it is provided between the heat dissipation base 3 and the reflector 1 to promote the heat conduction rate between the heat dissipation base 3 and the reflector 1.
[0214] Optionally, a carbon-containing layer may further be provided on the exposed surface of the heat dissipation base 3 , thereby improving the heat dissipation performance of the heat dissipation base 3 .
[0215] Optionally, the carbon-containing layer 91 may be a material such as graphene material, graphite powder, graphite sheet or graphite film, and may be provided by plating, spraying, laminating or the like where the carbon-containing layer 91 described herein is provided.
[0216] Optionally, the heat dissipation base 3 may be a ceramic base, with a first slot 31 formed in the ceramic base, and the reflector 1 embedded in the first slot 31. The first slot 31 is elongated and has an arc-shaped segment at its bottom. The reflector 1 is embedded in the first slot 31, which, on the one hand, increases the contact area between the reflector 1 and the heat dissipation base 3, and the heat dissipation base 3 dissipates heat from the reflector 1 through its excellent thermal conductivity, thereby reducing the heat radiation of the entire epilator. On the other hand, the first slot 31 is opened in the heat dissipation base 3, improving the space utilization rate of the heat dissipation base 3 and making the internal structure of the epilator more compact. Furthermore, ceramic is an insulator and will not short-circuit when in contact with the reflector 1. The reason why the body of the light source 2 can be suspended within the cavity is that the reflector 1 is a conductor, is spaced apart from the light source 2, and, when energized, uses a strong electric field to excite the light source 2 to emit light.
[0217] Optionally, a first fastener 32 is integrally formed on each side of the heat dissipation base 3, and a second fastener 51 is integrally formed on each side of the holder 5, with the first fastener 32 and the second fastener 51 corresponding to each other. When the heat dissipation base 3 and the holder 5 are connected, the first fastener 32 and the second fastener 51 are firmly engaged with each other, further ensuring a reliable connection between the heat dissipation base 3 and the holder 5 and thereby improving the stability of the epilator in use. Optionally, the first fastener 32 may be an engagement block or a cantilever hook, and the second fastener 51 may be a fixing hole. When the cantilever hook is embedded in the fixing hole, the fixing hole prevents the cantilever hook from easily coming off the fixing hole, ensuring a reliable connection between the first fastener 32 and the second fastener 51, i.e., the heat dissipation base 3 and the holder 5 are fixed relative to each other, effectively preventing the heat dissipation base 3 and the holder 5 from loosening or coming off from each other and improving the stability of the entire epilator.
[0218] Optionally, the holder 5 is provided with a window 52 through which light passes, and the dimensions of the portion of the window 52 corresponding to the second fastener 51 are larger than the dimensions of the portion where the ceramic-based first fastener 32 is provided, so that the portion where the ceramic-based first fastener 32 is provided is embedded in the window 52 of the holder 5. When the ceramic base and the holder 5 are actually assembled, the side of the ceramic base closer to the holder 5 is embedded in the window 52, which can more stably connect the ceramic base and the holder 5, while also reducing the gap between the ceramic base and the holder 5 and reducing the heat inside the reflector 1 that is radiated to the outside of the reflector 1, thereby improving the performance of the entire epilator.
[0219] 31, 32 and 34, the epilator includes side reflecting members 6 that are provided at both ends of the reflector 1 in the longitudinal direction and that reflect light leaking from both ends of the reflector 1 toward the light exit side of the reflector 1. The light emitted by the light source 2 can be sufficiently reflected by the side reflecting members 6, thereby improving the light utilization rate.
[0220] Optionally, the side reflector 6 has a through-hole 61, the diameter of which is larger than the diameter of the end of the lamp, and the end of the lamp passes through the through-hole 61. When installing the lamp, the lamp can be passed through one of the through-holes 61 or can be passed through the reflector 1 into the through-hole 61, thereby facilitating lamp installation. Optionally, the elastic body 4 can be a silicone sleeve or a soft rubber sleeve. The examples of this application use a silicone sleeve, which is merely illustrative and does not limit the elastic body 4. The light source 2 can be a lamp, which has an elongated cylindrical shape and a mounting post 21 extending from each end of the lamp, the radius of the mounting post 21 being smaller than the radius of the lamp. Specifically, the silicone sleeve is cylindrical and has a mounting groove 41, and both ends of the lamp are embedded in the mounting groove 41. The silicone sleeve has a fixing hole 42 drilled along its axis, which communicates with the mounting groove 41, and the fixing post 21 can pass through the fixing hole 42.
[0221] Furthermore, the through-holes 61 assist in accurately assembling the lamp to the reflector 1, shortening the installation time and improving installation efficiency. When the reflector 1 and lamp are assembled, the opening of the mounting groove 41 faces the reflector 1, and both ends of the lamp pass through the through-holes 61 and are inserted into the mounting groove 41. The silicone sleeve elastically presses the lamp against the side of the through-hole 61 closest to the bottom of the reflector 1, reducing hard contact between the lamp and the side reflector 6 and minimizing collisions between the side reflector 6 and the lamp. Even if a collision does occur, the silicone sleeve provides a cushion, effectively extending the lamp's service life and reducing usage costs.
[0222] 31, 32, and 34, optionally, second slots 33 are provided at both ends of the ceramic base where the first slots 31 are provided. The second slots 33 are used to accommodate the end of the light source 2 and the elastic body 4. On the one hand, this saves space and improves the space utilization rate of the ceramic base. On the other hand, the second slots 33 reduce external collisions between the end of the light source 2 and the elastic body 4, providing a relatively safe space for the end of the light source 2 and the elastic body 4. The second slots 33 communicate with the first slots 31, and the depth of the second slots 33 is greater than the depth of the first slots 31. The second slots 33 function as a space for retracting the elastic deformation of the elastic body 4. This prevents the elastic body 4 from pressing against the groove walls of the second slots 33, facilitating elastic deformation of the elastic body 4 itself. The elastic body 4 deforms according to the actual situation, and absorbs the external force during the deformation process, making the mounting post 21 less likely to be damaged or broken, reducing the number of times the light source 2 needs to be replaced, reducing operating costs, and improving the practicality of the epilator.
[0223] 31, 32 and 34, optionally, the epilator includes a first optically transparent body 7 provided on the light emission side of the reflector 1 and fixed to the holder 5, and the first optically transparent body 7 and the reflector 1 form a cavity for accommodating the light source 2. The first optically transparent body 7 may be an optical filter, and by filtering light with the optical filter, it is possible to easily select a wavelength suitable for epilating a skin portion, thereby reducing damage to the skin caused by light emitted from the light source 2 when the skin is irradiated with the light during operation of the epilator, and improving the safety of hair removal.
[0224] Optionally, the epilator includes a second optically transparent body 8, which is square or rectangular and embedded in the window 52. The second optically transparent body 8 is located on the side of the optical filter facing away from the light source 2, and has an incident surface 81 facing the light source 2 and an exit surface 82 facing away from the light source 2. Optionally, the second optically transparent body 8 may be a crystal, such as a diamond, and crystal will be used as an example in the embodiments of the present application. When the epilator is operating, the light source 2 emits light, the reflector 1 reflects the light, and the light passes through the optical filter and is reflected by the crystal. The light enters the incident surface 81, is reflected by the crystal body, and exits from the exit surface 82. The light exiting from the exit surface 82 is irradiated onto the area of the skin to be epilated, thereby easily removing hair on the skin.
[0225] Optionally, the epilator includes a cooling member 9, the cooling side of which is thermally coupled to the other side of the heat dissipation base 3, to cool the space within the reflector 1. For example, the cooling member 9 may be a TEC cooling sheet or a cooling block, which is used to cool the heat dissipation base 3, thereby achieving the purpose of instantly and quickly removing the heat on the heat dissipation base 3 and quickly dissipating the heat from the reflector 1. In one example of the present application, the adopted cooling member 9 is a TEC cooling sheet, which is merely illustrative and not limiting.
[0226] During operation of the epilator, the light source 2 emits a large amount of light within the reflector 1. The heat generated by this light accumulates within the cavity, causing the temperature of the reflector 1 to rise as the heat concentrates within the cavity. One side of the heat dissipation base 3 is thermally coupled to the reflector 1, and the cooling element 9 is thermally coupled to the other side of the heat dissipation base 3. The thermal coupling can transfer heat via thermal conduction, thermal convection, thermal radiation, or any combination of these three methods. That is, the heat dissipation base 3 can transfer heat from the reflector 1 to the outside while simultaneously dissipating heat within the cavity, thereby cooling the reflector 1 and the cavity, thereby improving the heat dissipation efficiency of the light source 2. Hanging the body of the light source 2 in the cavity also allows for more uniform heat dissipation from the light source 2, which is beneficial for extending the service life of the light source 2. Specifically, heat generated when the light source 2 is operating is dissipated to the surroundings in the form of radiation, and the air medium is uniformly wrapped around the light source 2 and in sufficient contact with the light source 2, thereby uniformly dissipating the heat generated by the light source 2. Heat generated by the light source 2 passes through the cavity and is transferred to the reflector 1 and the first light-transmitting body 7 for dissipation. Furthermore, the cooling element 9 transfers the heat on the heat dissipation base 3 for rapid heat dissipation, further improving the heat dissipation effect of the epilator while reducing the radiation of heat from the cavity to other parts of the epilator, thereby reducing the burning sensation on the epilated skin during use and improving the usability of the epilator.
[0227] Optionally, a carbon-containing layer may be provided on the side of the cooling member 9 facing the heat dissipation base 3 or on the exposed surface of the cooling member 9. The carbon-containing layer has excellent thermal conductivity and can improve the cooling effect of the cooling member 9, thereby immediately and quickly removing heat from the heat dissipation base 3 and achieving the purpose of quickly dissipating heat from the reflector 1.
[0228] This embodiment has the following beneficial effects: Different from the prior art, this application discloses a hair removal device including a reflector 1 and a light source 2. The light source 2 is: Rod-shapedThe gas-excited light source is assembled to a reflector 1, with the distance between the body of the light source 2 and the reflector 1 being 0.3 mm or less, so that when the reflector 1 is energized, it generates a high voltage, ionizing the gas in the light source 2 to generate an arc and further discharge, thereby causing the light source 2 to emit light. The reflector 1 is a conductor and therefore easily conductive, providing a location where a high voltage can be generated. By limiting the distance between the light source 2 and the reflector 1, the voltage within the reflector 1 can excite the light source 2 to emit light. Compared to the method of triggering the lamp to emit light via a trigger wire, the reflector 1 that triggers the lamp to emit light without a trigger wire not only improves the method of triggering the lamp to emit light and increases luminous efficiency, but also saves materials and reduces manufacturing costs.
[0229] Referring to Figure 35, Figure 35 is a schematic diagram showing the structure of one embodiment of the present application. Here, the hair removal device includes a head 111 and a handle 112 connected to the head 111. The head 111 is provided with a cooling unit 1111 for contact with the skin. The cooling unit 1111 emits light to irradiate hair follicles on the user's skin, allowing the light to penetrate the skin and irradiate the hair follicles to remove hair, while also rapidly lowering the temperature, reducing the burning sensation caused by the light on the skin and preventing the user from feeling uncomfortable during use. In some embodiments, the cooling unit 1111 can also emit light for skin care, thereby allowing the hair removal device to have both hair removal and skin care functions.
[0230] Referring to Figures 40 and 41, in another embodiment of the epilator of the present application, an elastic sealing ring 16 is provided between the first light-transmitting body 7 and the second light-transmitting body 3, the elastic sealing ring 16 is annular, and both the first light-transmitting body 7 and the second light-transmitting body 3 are fitted together to seal with the elastic sealing ring 16, so that condensation does not occur between the second light-transmitting body 3 and the first light-transmitting body 7, and some dirt cannot enter the connection point between the second light-transmitting body 3 and the first light-transmitting body 7, and the elastic sealing ring 16 is preferably annular.
[0231] Of course, if the epilator is accidentally dropped to the ground, a rigid-body collision may occur between the second light-transmitting body 3 and the ground, and in the conventional second light-transmitting body 3, the impact force may be transmitted to the first light-transmitting body 7, further damaging the first light-transmitting body 7, the reflector 1, and the light source 2. In the epilator of this embodiment, the impact force when the second light-transmitting body 3 collides can be counteracted by the elastic seal ring 16, and when pressed by an external force, the elastic seal ring 16 causes elastic deformation due to its own elasticity, thereby reducing or counteracting the impact between the first light-transmitting body 7 and the second light-transmitting body 3, thereby reducing the possibility that the first light-transmitting body 7, the reflector 1, and the light source 2 will be damaged by such impacts, and further improving the collision avoidance performance of the epilator.
[0232] Further, referring to Figures 42 to 44, the elastic sealing ring 16 is provided with an inner ring 161 for passing light, and the light filtered by the first light-transmitting body 7 is guided to the second light-transmitting body 3 via the inner ring 161 so that it can be irradiated onto human skin.
[0233] In this embodiment, the first light-transmitting body 7 and the second light-transmitting body 3 are both directly fixed to the holder 6 and cannot move relative to the holder 6. This effectively prevents a bone or a sharp object from hitting the second light-transmitting body 3 during use, causing the second light-transmitting body 3 to retreat relative to the holder 6, thereby preventing irreversible deformation of the first light-transmitting body 7 or the hair removal assembly 100. Furthermore, even if the elastic sealing ring 16 is pressed multiple times and irreversible deformation occurs, it is possible to avoid wasting light energy due to the impact on the light-guiding effect of the hair removal device.
[0234] The elastic sealing ring 16 further has an attachment groove 162 communicating with the inner ring 161, the attachment groove 162 being located on the side of the elastic sealing ring 16 away from the hair removal assembly 100, the inner ring 161 extending through from the bottom wall of the attachment groove 162 toward the side of the first light-transmitting body 7, and the second light-transmitting body 3 being partially attached within the attachment groove 162, thereby improving the sealing performance between the second light-transmitting body 3 and the elastic sealing ring 16 and fixing the elastic sealing ring 16 to the second light-transmitting body 3 to achieve a fixed connection between the two.
[0235] In a preferred embodiment, the elastic sealing ring 16 includes an outer ring 163 and a protrusion 164 protruding from one side of the outer ring 163, the protrusion 164 abutting the first light-transmitting body 7, a mounting groove 162 is provided on the side of the outer ring 163 away from the protrusion 164, the inner ring 161 extends from the bottom wall of the mounting groove 162 to one side of the protrusion 164, and both the outer ring 163 and the protrusion 164 form a completely closed loop structure, and light within the inner ring 161 can only be transmitted from the second light-transmitting body 3.
[0236] In a preferred embodiment, the cross section of the protrusion 164 is a transverse triangular structure, and the contact area of the protrusion 164 with the first optically transparent body 7 is smaller than the contact area of the protrusion 164 with the outer ring 163. Therefore, when the elastic sealing ring 16 is installed, the end of the protrusion 164 away from the outer ring 163 can be partially warped when pressed. Because the elastic sealing ring 16 is elastic, the warped portion of the elastic sealing ring 16 can firmly abut against the first optically transparent body 7. That is, even if the gap between the second optically transparent body 3 and the first optically transparent body 7 changes slightly, the warped portion of the elastic sealing ring 16 can adapt to this gap change. Therefore, a tight or interference fit is always maintained between the elastic sealing ring 16 and the second optically transparent body 3 and between the elastic sealing ring 16 and the first optically transparent body 7, resulting in better sealing. Of course, in other embodiments, the cross section of the protrusion 164 may be a trapezoidal structure.
[0237] In this embodiment, the elastic sealing ring 16 is an annular body made of a material that is laser-resistant and resistant to high and low temperatures, thereby preventing the elastic sealing ring 16 from being deformed by high or low temperatures or laser irradiation during use, and extending the service life of the elastic sealing ring 16.
[0238] Optionally, the grip portion 112 may include a hollow shell (not numbered in the figures), with air permeable holes 1211 provided on the surface of the shell, which communicate the interior of the shell with the outside world, allowing the hair removal device to exchange air with the outside world through the air permeable holes 1211 and lower the temperature inside. The shell further includes a port 1212, which can be used to connect to an external power source and charge the hair removal device. Here, the location of the port 1212 on the shell is not limited.
[0239] 35 and 36, Fig. 36 is a schematic diagram showing an exploded structure of one embodiment of the present application, where the arrows shown in Fig. 36 represent the flow direction of air in the hair removal device under the driving of the cooling driving assembly, the straight lines represent the cold air flow, and the waves represent the hot air flow. Specifically, the hair removal device may include a shell, a light cover 113 provided at the opening of the shell, a hair removal mechanism 14 housed inside the shell, and a bottom cover 15.
[0240] In this embodiment, the shell may include a first shell 121 and a second shell 122, which are connected to each other in an engaging manner to form a cavity with openings at both ends, the hair removal mechanism 14 is housed in the cavity, and the light cover 113 and the bottom cover 15 are respectively provided to cover the two openings and are used to seal the openings after the first shell 121 and the second shell 122 are connected to form the cavity.
[0241] Optionally, the first shell 121, the second shell 122, the light cover 113 and the bottom cover 15 may be connected by snaps, or may be connected by screws or adhesive.
[0242] The epilation mechanism 14 includes an epilation assembly 100 , a cooling sensation assembly 200 , a heat dissipation assembly 300 and a cooling drive assembly 400 .
[0243] The cooling sensation assembly 200 is provided on the side close to the light cover 113, and the light cover 113 is provided with a through-hole (not provided with a reference number), and a part of the cooling sensation assembly 200 is exposed to the outside world from the inside of the shell through the through-hole of the light cover 113 and comes into direct contact with the skin. As can be understood, a part of the cooling sensation assembly 200 and the light cover 113 form the head 111 of the hair removal device.
[0244] The hair removal assembly 100 is provided on the side of the cooling sensation assembly 200 away from the light cover 113 and is used to emit light to the cooling sensation assembly 200. The light may be visible light such as red light, green light, or yellow light. The light is incident on the cooling sensation assembly 200 and passes through the cooling sensation assembly 200 to enter the hair follicles under the skin, thereby achieving hair removal.
[0245] The heat dissipation assembly 300 is provided on one side of the cooling sensation assembly 200 and is connected to the cooling sensation assembly 200. When the cooling sensation assembly 200 is placed against the skin, it absorbs heat from the skin, lowering the skin temperature and reducing the burning sensation. However, if the cooling sensation assembly 200 is used for a long time, its temperature will rise and its cooling effect will decrease. The heat dissipation assembly 300 absorbs the heat from the cooling sensation assembly 200, maintaining the cooling sensation assembly 200 in a low-temperature working environment and ensuring the cooling effect of the cooling sensation assembly 200 on the skin. Therefore, the hair removal device of this embodiment can maintain a low temperature even when used continuously, without causing pain to the user.
[0246] The cooling drive assembly 400 is provided on the side of the heat dissipation assembly 300 where at least a portion of the assembly faces away from the epilation assembly 100 , and is used to dissipate heat from the epilation assembly 100 and the heat dissipation assembly 300 .
[0247] In this embodiment, the cooling drive assembly 400 draws in the external cooling medium and introduces it into the inside of the hair removal device through the air permeation hole 1211, and the cooling medium passes through the hair removal assembly 100 and the heat dissipation assembly 300 to carry away heat, and then flows out through the air permeation hole 1211.
[0248] Optionally, the external cooling medium may be air, and the cooling drive assembly 400 draws in air and blows it onto the epilation assembly 100 and the heat dissipation assembly 300, and the heat of the epilation assembly 100 and the heat dissipation assembly 300 is carried away by the airflow.
[0249] In this embodiment, the air permeation holes 1211 are provided in the first shell 121, and at least a portion of the cooling drive assembly 400 faces the air permeation holes 1211, so that the cooling drive assembly 400 can better absorb the external cooling medium through the air permeation holes 1211 and improve heat dissipation efficiency. In other embodiments, the air permeation holes 1211 may be provided in the second shell 122.
[0250] 36 and 37, FIG. 37 is a schematic diagram showing an exploded structure of the embodiment of FIG. 36, where the arrows shown in FIG. 37 indicate the direction of air exiting the fan.
[0251] In this embodiment, the hair removal device further includes a holder 500, a circuit board 600, a processor 700, and a capacitor 800, wherein the hair removal assembly 100 and the cooling sensation assembly 200 are mounted in the holder 500, and the cooling drive assembly 400 is provided adjacent to the holder 500. The hair removal assembly 100, the cooling sensation assembly 200, and the cooling drive assembly 400 are mounted on the circuit board 600 and electrically connected to the circuit board 600.
[0252] The processor 700 and the capacitor 800 are electrically connected to and mounted on the circuit board 600. When connected to an external power source, the external power source can charge the capacitor 800 so that the capacitor 800 can power the hair removal device, and the capacitor 800 can store power when connected to an external power source, allowing the hair removal device to be used even when not connected to an external power source. The processor 700 sends control commands to the hair removal assembly 100, the cooling sensation application assembly 200, and the cooling drive assembly 400 to control the operation of the hair removal device, such as controlling the switches of the hair removal device, thermal protection, power regulation, etc.
[0253] In this embodiment, the circuit board 600 may be fixed in the second shell 122, and the circuit board 600 may be selected as a PCBA circuit board.
[0254] In related art, the heat inside the hair removal device body often increases during use, and the internal circuits and components of the hair removal device are prone to explosion, burning, short circuit, etc. in a high-temperature environment. In this embodiment, the cooling drive assembly 400 can dissipate heat from the hair removal assembly 100 and the heat dissipation assembly 300, and the heat dissipation assembly 300 can dissipate heat from the cooling sensation assembly 200, so that the cooling sensation assembly 200 can ice the skin to increase skin comfort and prevent problems such as explosion, burning, short circuit, etc. caused by excessively high temperatures.
[0255] Specifically, the hair removal assembly 100 may include a light source 101 , a reflector 102 , a light filter 103 and two electrodes 104 .
[0256] The light source 101, the reflector 102 and the optical filter 103 are mounted in the holder 500, i.e., mounting locations for the light source 101, the reflector 102 and the optical filter 103 are provided in the holder 500, and the light source 101, the reflector 102 and the optical filter 103 are engaged into the mounting locations of the holder 500.
[0257] Here, the light source 101 is disposed opposite the cooling sensation assembly 200, and light emitted from the light source 101 can be directly incident on the cooling sensation assembly 200. The reflector 102 is disposed on the side of the light source 101 away from the cooling sensation assembly 200 and reflects the light from the light source 101 to the cooling sensation assembly 200, preventing loss of light energy. The optical filter 103 is located between the light source 101 and the cooling sensation assembly 200. That is, the light source 101, the optical filter 103, and the cooling sensation assembly 200 are sequentially arranged along the light propagation direction. The optical filter 103 is used to filter out some of the harmful light emitted from the light source 101, reducing damage to the skin caused by light and improving safety during hair removal. Two electrodes 104 are connected to either side of the light source 101 and electrically connected to the circuit board 600 for transmitting electrical signals.
[0258] Optionally, the light source 101 may be a lamp, and the color of the light emitted by the lamp is not limited, and may be colored light, synthetic light, etc., and the specific wavelength and frequency are determined according to the application. The type of the lamp is also not limited, and may be a semiconductor xenon lamp, a quartz lamp, a laser lamp, etc., and the type of photons may be IPL (Intense Pulse Light), DPL (Delicate Pulse Light), OPT (Optimal Pulse Technology), AOPT (Advanced Optimal Pulse Technology), BBL (BroadBand Light), etc., and the specific type is determined according to the desired effect.
[0259] Optionally, the reflector 102 may be a U-shaped reflector surrounding the light source 101, and the opening of the U-shaped reflector may be directed toward the cooling sensation assembly 200 to reflect light that does not enter the cooling sensation assembly 200 to the cooling sensation assembly 200. At the same time, the reflector 102 may also prevent heat generated by the light source 101 from dissipating to other components in the hair removal device. In this embodiment, the holder 500 includes a fixed holder 550 and a pipe 560, and a first receiving space 510 and a second receiving space 520 are provided inside the fixed holder 550. Here, the first accommodating space 510 is used to mount the hair removal assembly 100, and the second accommodating space 520 is used to mount the cooling sensation assembly 200. The first accommodating space 510 and the second accommodating space 520 are arranged adjacent to each other, thereby shortening the distance between the hair removal assembly 100 and the cooling sensation assembly 200 and reducing the optical path loss of the light emitted from the hair removal assembly 100, and the second accommodating space 520 is closer to the head 111 of the hair removal device shown in Figure 35 than the first accommodating space 510.
[0260] When the hair removal device is in operation, the light source 101 generates a large amount of heat, and the reflector 102 and the optical filter 103 are also irradiated with light, which leads to an increase in temperature, so it is necessary to dissipate heat from the light source 101, the reflector 102 and the optical filter 103.
[0261] In this embodiment, the holder 500 includes a fixed holder 550 and a pipe 560, one end of which is connected to one side of the fixed holder 550 and the other end of which extends toward the cooling drive assembly 400. An air outlet 540 communicating with the first accommodating space 510 is provided within the fixed holder 550, and an air inlet 530 communicating with the first accommodating space 510 is provided in the pipe 560, so that the air inlet 530, the first accommodating space 510, and the air outlet 540 are sequentially connected to each other.
[0262] The air inlet 530 communicates with the cooling drive assembly 400, and the air outlet 540 communicates with the air permeation holes 1211. The cooling drive assembly 400 draws in outside air through the air permeation holes 1211 and blows it out through the air outlet 540. After entering the first accommodating space 510 through the air outlet 540, the air absorbs heat from the light source 101, reflector 102, and optical filter 103 in the first accommodating space 510 and flows out through the air outlet 540 and the air permeation holes 1211 to the outside, dissipating the heat to the outside.
[0263] Optionally, a portion of each of the fixed holder 550 and the pipe 560 forms a first holder 501, and the remaining portion of each of the fixed holder and the pipe forms a second holder 502; in other embodiments, the fixed holder 550 may be integrally formed.
[0264] The first holder 501 and the second holder 502 can be connected together by snaps. The first holder 501 is adjacent to the first shell 121, and the second holder 502 is adjacent to the second shell 122. An air outlet 540 is provided in the first holder 501 and opposite the air permeation hole 1211 of the first shell 121, thereby accelerating the heat dissipation efficiency of the air outlet 540. The first accommodating space 510 is provided within the first holder 501 and the second holder 502, where the corresponding portions of the fixed holder 550 are engaged. The air inlet 530 is provided within the first holder 501 and the second holder 502, where the corresponding portions of the pipe 560 are engaged, and communicates with the first accommodating space 510 and the cooling drive assembly 400. An air conduction path may be provided within the holder 500 to facilitate guiding the airflow from the cooling drive assembly 400 into the first accommodating space 510.
[0265] Therefore, in this embodiment, the epilating assembly 100 dissipates heat through the cooling drive assembly 400, ensuring the safe use of the epilating device.
[0266] Furthermore, in this embodiment, the cooling sensation assembly 200 may include a second optically transparent body 201 and a cooling member 202 .
[0267] The second light-transmitting body 201 is used to be applied to the skin and is arranged opposite the light source 2. The second light-transmitting body 201 is a light-transmitting part, and the light emitted from the light source 101 enters the second light-transmitting body 201 and is then emitted from the second light-transmitting body 201 to the skin.
[0268] Optionally, the second optically transparent body 201 may be made of a light-conducting crystal, such as sapphire, K9 glass, or crystal glass, and when made of sapphire, the second optically transparent body 201 has excellent thermal conductivity.
[0269] Optionally, the second optically transparent body 201 may be a cylindrical or rectangular body, and the surface of the second optically transparent body 201 away from the light source 2 is used to apply to the skin.
[0270] The cooling member 202 is connected to the second optically transparent body 201 and is used to absorb heat from the second optically transparent body 201. When the second optically transparent body 201 comes into contact with the skin, its temperature rises, and the cooling member 202 absorbs the heat from the second optically transparent body 201 after the temperature of the second optically transparent body 201 rises, thereby maintaining the second optically transparent body 201 at a low temperature. As a result, even if the second optically transparent body 201 is applied to the skin for a long period of time, the skin can be cooled and pain on the skin can be reduced.
[0271] Furthermore, the cooling member 202 may be a semiconductor cooling type cooling component, the heat absorption end of which is connected to the second light transmitting body 201 and the other end of which dissipates heat.
[0272] In order to dissipate heat from the heat dissipation end of the cooling member 202 , in this embodiment, a heat dissipation assembly 300 is connected to the heat dissipation end of the cooling member 202 to absorb the heat of the cooling member 202 .
[0273] Specifically, the heat dissipation assembly 300 includes a heat dissipation plate 301 and heat dissipation fins 302. A first region 310 and a second region 311 are arranged side by side on one side of the heat dissipation plate 301, the hair removal assembly 100 is arranged in the first region 310, and the heat dissipation fins 302 are attached to the second region 311. The second region 311 is located on one side of the fixed holder 550 where the pipe 560 is connected, the heat dissipation fins 302 and the pipe 560 are arranged side by side on one side of the fixed holder, and the fixed holder 550 is arranged in the first region 310. The heat dissipation plate 301 is attached to the circuit board 600 and connected to the cooling assembly 200, and specifically, the cooling member 202 can be bonded to the heat dissipation plate 301 with thermally conductive silicone grease. The cooling assembly 200 can quickly conduct heat to the heat dissipation plate 301 through the thermally 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 continue to absorb heat from the cooling member 202.
[0274] Optionally, there are a plurality of heat dissipation fins 302, the plurality of heat dissipation fins 302 are parallel to each other, and the heat dissipation fins 302 can be attached to the heat dissipation plate 301 by welding.
[0275] Optionally, a thermally conductive paint can be sprayed onto the surface of the heat dissipation fins 302, which can not only dissipate heat from the heat dissipation fins 302, but also prevent water vapor from affecting the heat dissipation fins 302, and is also resistant to corrosion and abrasion.
[0276] In this embodiment, the heat dissipation plate 301 may be a vapor chamber, in which the liquid working substance inside absorbs heat by evaporating and liquefying when heated, and then cools and dissipates heat, thereby maintaining the surface temperature of the vapor chamber constant through the cycle of evaporation and condensation. Therefore, part of the surface of the heat dissipation plate 301 is connected to the cooling element 202, and the other part is connected to the heat dissipation fins 302, and the heat generated in the cooling element 202 is dissipated through the heat dissipation plate 301 and the heat dissipation fins 302.
[0277] Optionally, referring to FIG. 38 , a carbon-containing layer 92 may be provided between the second light-transmitting body 201 and the heat dissipation assembly 300, for example, on the surface of the heat dissipation plate 301 that is thermally coupled to the second light-transmitting body 201. The carbon-containing layer 92 has excellent thermal conductivity, which can accelerate the thermal conductivity of the heat dissipation plate 301 and improve the heat dissipation performance of the heat dissipation assembly 300.
[0278] Optionally, carbon-containing layer 92 is a graphene material, graphite powder, graphite sheets, or graphite films.
[0279] Optionally, the carbon-containing layer 92 is applied by plating, spraying, or laminating.
[0280] In order to improve the heat dissipation performance of the heat dissipation assembly 300, in this embodiment, the heat dissipation assembly 300 further communicates with a cooling drive assembly 400.
[0281] Specifically, the heat dissipation fins 302 of the heat dissipation assembly 300 are connected to the cooling drive assembly 400, and the cooling drive assembly 400 draws in outside air through the air permeation holes 1211 and drives the air to blow onto the heat dissipation fins 302, so that the air flows through the heat dissipation fins 302 and causes the heat dissipation fins 302 to dissipate heat.
[0282] In an exemplary embodiment, the heat dissipation fins 302 are arranged in a square shape and parallel to the airflow provided by the cooling drive assembly 400, thereby increasing the area of the heat dissipation fins 302 that comes into contact with the airflow and accelerating the heat dissipation efficiency of the heat dissipation fins 302.
[0283] The heat dissipation fins 302 are provided opposite the air passage holes 1211 on the first shell 121 , and the airflow passes through the heat dissipation fins 302 and then quickly flows out through the air passage holes 1211 .
[0284] Therefore, the cooling driving assembly 400 in this embodiment can drive the cooling medium to not only dissipate heat from the hair removal assembly 100, but also dissipate heat from the heat dissipation assembly 300. With improved safety performance, the irradiated skin can be cooled to a cool sensation, reducing the burning pain caused by the irradiated skin, and the cooling driving assembly 200 can reach a low temperature close to 0°C under the action of the heat dissipation assembly 300 and the cooling driving assembly 400, allowing the skin near the light outlet to approach the freezing point indefinitely, thereby reducing the burning pain of the skin and preventing damage to the skin due to short-term contact.
[0285] 36, 37, and 39, Fig. 39 is a schematic diagram showing a structure at an air outlet of the fan housing in the embodiment of Fig. 37. In this embodiment, the cooling drive assembly 400 may include a fan housing 401 and a fan 402. The fan housing 401 is provided on the side of the heat dissipation assembly 300 facing away from the cooling sensation assembly 200, and the fan 402 is housed within the fan housing 401.
[0286] One end of the intake of the fan 402 faces the air permeation hole 1211 on the first shell 121, and the fan 402 is driven to send outside air into the fan 402 from the air permeation hole 1211. The fan housing 401 is provided with an air outlet 410 for blowing out air, and one end of the air outlet of the fan 402 is connected to the air outlet 410. The fan 402 is driven to draw outside air into the fan 402 from the air permeation hole 1211 and then discharge the air from the air outlet 410.
[0287] Optionally, fan 402 may be a centrifugal fan, an axial flow fan, a mixed flow fan, or a cross flow fan.
[0288] Furthermore, the air outlet 410 includes a first air outlet 411 and a second air outlet 412, and the air from the air outlet 410 of the fan 402 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.
[0289] Optionally, the air outlets 410 may include a third air outlet or more air outlets, but are not limited thereto.
[0290] In this embodiment, the first air outlet 411 is connected to the air inlet 530 of the holder 5, and the fan 402 is driven to draw outside air into the fan 402 through the air permeation hole 1211, and the fan 402 is driven to draw airflow through the first air outlet 411 and the air inlet 530 into the first accommodating space 510, which removes heat from the light source 2, the reflector 1 and the optical filter 103 in the first accommodating space 510, and finally flows out to the outside through the air exhaust port 540 and the air permeation hole 1211, thereby realizing heat dissipation of the hair removal assembly 100.
[0291] In this embodiment, the second air outlet 412 is connected to the heat dissipation fins 302 of the heat dissipation assembly 300, and the fan 402 is driven to draw outside air into the fan 402 through the air permeation holes 1211. The fan 402 is driven to draw airflow from the second air outlet 412 into between the heat dissipation fins 302 of the heat dissipation assembly 300, the airflow passes through the heat dissipation fins 302 to remove heat therefrom, and then flows out through the air permeation holes 1211. When the temperature of the heat dissipation fins 302 decreases, the heat of the heat dissipation plate 301 is also reduced, so that the heat dissipation plate 301 can absorb the heat of the cooling assembly 200 and realize heat dissipation of the cooling assembly 200.
[0292] Optionally, the airflow rates at the first air outlet 411 and the second air outlet 412 are not limited and are set according to actual conditions. The airflow rates at the first air outlet 411 and the second air outlet 412 can be controlled by setting the sizes of the first air outlet 411 and the second air outlet 412. For example, in this embodiment, the air blowing area of the second air outlet 412 is larger than the air blowing area of the first air outlet 411, so that more air flows out from the second air outlet 412 and improves the heat dissipation efficiency of the heat dissipation plate 301.
[0293] From the above, the hair removal device of this embodiment uses the cooling drive assembly 400 to dissipate heat from the hair removal assembly 100, the cooling sensation assembly 200 and the heat dissipation assembly 300, and further realizes simultaneous heat dissipation from the hair removal assembly 100 and the cooling sensation assembly 200, thereby improving the heat dissipation performance of the hair removal device, increasing the safety factor of the hair removal device, and making the cooling sensation on the skin infinitely close to the freezing point, reducing the burning pain on the skin, and preventing damage to the skin during hair removal.
[0294] The above are merely embodiments of the present application and do not limit the scope of protection of the present application, but any equivalent structure or equivalent process transformation made by using the contents of the specification and accompanying drawings of the present application, or direct or indirect application to other related technical fields, are all similarly included in the patent protection scope of the present application.
