Abstract
Description
[Technical Field]
[0001] The present invention relates to the technical field of beauty equipment, and in particular to a hair removal device. [Background technology]
[0002] Prior art hair removal devices use high-energy light sources, such as pulsed light or laser light, to generate high-energy light and ablate hair. Such high-energy light (or pulsed light / laser light itself) can irritate and injure the user's eyes, damage the skin, and even cause burns and other hazards. Photothermal radiation is highly damaging to the skin and is not necessarily safe for use. Generating pulsed light or laser light requires high voltage (e.g., higher than 8000 V), and the use of such high voltage poses safety issues. Furthermore, specific components (e.g., a specific power supply or trigger mechanism) are required to excite the pulsed light or laser light, resulting in a large device volume and high costs. High-energy light sources consume a lot of energy and are unfriendly to the environment. Furthermore, the spectral bandwidth available from pulsed light and laser light sources is limited and insufficient for use, making them difficult to use for cosmetic or therapeutic functions other than hair removal. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION
[0020] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings. Although the drawings show exemplary embodiments of the present invention, it should be understood that the present invention should not be limited to the embodiments described herein. On the contrary, these embodiments are provided to provide a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0021] It should be understood that the terminology used herein is for the purpose of describing the purpose of particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a," "one," and "the" may also refer to the plural, unless the context clearly indicates otherwise. The terms "comprise," "include," "contain," and "have" are inclusive and thus specify the presence of stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. Unless an order of execution is explicitly stated, the described method steps, processes, and actions should not be construed as requiring them to be performed in the particular order stated or described. Additionally, additional or alternative steps may be employed.
[0022] For convenience of explanation, spatially relative terms may be used herein to describe the relationship of one element or feature shown in the drawings to other elements or features. These relative terms may include, for example, "interior," "exterior," "inside," "outside," "lower," "below," "top," "upper," "front," "rear," etc. Such spatially relative terms are intended to encompass different orientations of the device in use or operation other than the orientation depicted in the drawings. For example, if the device in the drawings is inverted, an element described as "under other elements or features" or "under other elements or features" would then be described as "over other elements or features" or "above other elements or features." Thus, the term "under..." can encompass both top and bottom orientations. The device may be oriented in other directions (rotated 90 degrees or in other directions) and interpreted accordingly. In the following examples, the forward and horizontal directions are defined as the directions in which light generated by the light source is projected onto the light exit window.
[0023] Referring to Figures 1 to 5, the present invention relates to an epilator 1000 including a housing, a light source assembly mounted within the housing, a power supply assembly, and a main control board 100. A light exit window is formed on the front surface of the head of the device, and the end surface of the light exit window can directly contact the skin. In one embodiment, the light exit window on the front end surface of the epilator 1000 is made of a transparent body, and the transparent light exit window 20 is fixed by an annular front housing 102. Light generated from the light source unit is projected onto the transparent light exit window 20 and irradiated onto the external skin for hair removal. The light source assembly and power supply assembly are electrically connected to the main control board 100. The housing has multiple vents, and the interior of the housing is a cavity. The multiple ventilation ports provided in the housing include an intake port 106 and an exhaust port 107, forming a ventilation passage within the body of the aircraft, which is in airflow communication with the intake port 106 and the exhaust port 107, allowing outside air or cool air to enter the ventilation passage within the body of the aircraft through the intake port 106, remove heat from heat-generating components, and be discharged to the outside of the aircraft through the exhaust port 107, thereby achieving heat dissipation. The intake port 106 and the exhaust port 107 may be in a variety of forms, such as a gap between the housings or one or more through holes provided in the housing, and may be provided on the same side or different sides of the housing, and the intake port and the exhaust port may be the same vent or different vents.
[0024] The housing includes a main housing 101 and a front housing 102 that engage with each other, forming a cavity inside the machine body. The front housing 102 is generally a housing at the front end of the head, but is not limited to a front end position and can be determined depending on the specific shape of the machine body. A base holder 40 is provided inside the machine body, and an internal holder 103 may also be provided. The holders 40 and 103, in combination with the housing, attach various components of the epilator. The light source assembly is attached to the inside of the front end of the machine body by the base holder 40, and the fan 90, heat sink 33, and main control board 100 are attached to the machine body in cooperation with the main housing 101 by the internal holder 103. The internal holder 103 attaches and protects the main control board 100 within the cavity formed by engaging with the main housing 101. A switch button 104, electrically connected to the main control board 100, is further attached to the housing and used for switching control or function setting.
[0025] The nozzle holder 40 is provided inside the front end of the body of the epilator 1000 and is used to attach a light source unit. The light source unit includes a halogen lamp 50, a light reflecting member 80 for attaching the halogen lamp 50, and a lens 60. The halogen lamp 50 is attached to the nozzle holder 40 by the light reflecting member 80. A light exit passage is formed inside one side (front side) of the light reflecting member 80. The terminal opening is a light exit port. A heat dissipation assembly for dissipating heat from the light reflecting member 80 is connected to the other side (rear side) of the light reflecting member 80, and the heat dissipation assembly includes a heat conduction member 81 and / or a heat sink 82. In the first embodiment, the heat dissipation assembly of the light-reflecting member includes a heat-conducting member 81 and a heat sink 82. The front surface of the heat-conducting member 81 matches the rear surface of the light-reflecting member 80, and they are bonded together to ensure rapid heat conduction. A heat sink 82 is further provided on the rear side of the heat-conducting member 81. The heat sink 82 includes a heat-conducting substrate and one or more sets of heat-dissipating fins. The heat sink 82 can extend rearward to the fan 90 vent and communicate with the fan duct. It is located in the ventilation passage within the housing to facilitate heat dissipation from the light source. The rear surface of the heat sink 82 may be configured in an arc shape to match the fan casing of the fan 90. Airflow within the fan cavity flows from the fan vent into the duct of the heat sink 82 to dissipate heat. Both ends of the halogen lamp 50 are electrically connected to the main control board 100 via electrodes 51. A filter 70 is provided in the optical path of the light source assembly, and may be provided at the light outlet of the light reflecting member 80. The filter 70 filters the light generated from the halogen lamp 50 to obtain output light of a predetermined wavelength, which is then projected onto the light output window on the head of the epilator for external skin treatment.
[0026] The transparent body light exit window 20 at the head tip of the epilator 1000 of the present invention is fixed by the front housing 102. In some embodiments, the transparent body (e.g., transparent crystal) forming the light exit window 20 may be cooled by the semiconductor cooling element 10, or the cold surface of the semiconductor cooling element 10 may be directly used as the light exit window 20 of the transparent body. This provides a cooling or pre-cooling effect on the skin outside the transparent body. The use of a semiconductor cooling device requires a heat dissipation assembly to be provided inside the epilator 1000 to dissipate the heat of the hot surface of the semiconductor cooling element 10. In other embodiments, the semiconductor cooling element 10 is used to cool the peripheral frame of the transparent body light exit window 20, and the peripheral frame comes into contact with the skin to provide a cooling or pre-cooling effect on the skin.
[0027] 1 and 2, a first embodiment of the epilator 1000 of the present invention is disclosed. Here, the back surface of the transparent body is adjacent to the cold surface of the annular semiconductor cooling member 10, and the annular semiconductor cooling member 10 is attached to the periphery of the transparent body to achieve a full-surface cooling effect. The semiconductor cooling member 10 includes an annular hot surface, a cold surface, and an intermediate semiconductor electric double layer. Exemplarily, the heat dissipation assembly of the cooling member includes an annular heat conductive member 31, a heat pipe 32, and a radiator 33. Here, the front end of the annular heat conductive member 31 is attached to the hot surface of the annular semiconductor cooling member 10, and its rear end (rear) is annularly attached to the front end of the heat pipe 32, and the radiator 33 is provided at the rear end of the heat pipe 32 (e.g., a set of heat dissipation fins is drilled at the rear end of the heat pipe). The cold surface of the semiconductor cooling member 10 cools the transparent body, and the heat of the semiconductor cooling member 10 is transferred from the hot surface to the heat conduction member 31, and then transferred to the radiator 33 via the heat pipe 32 and dissipated, thereby cooling the cold surface.
[0028] In the first embodiment, one side of the refrigeration element radiator 33 (along the axial direction) is located behind the air intake 106 of the housing, and the other side is the fan 90, and the duct of the radiator 33 is in communication with the air intake 106 and the (axial) vent of the fan 90. A duct 110 is formed by airflow communication between the air intake 106 of the housing, the duct of the radiator 33, the duct of the fan 90 (one (axial) vent of the fan, the fan cavity, another vent of the fan (for example, in the fan surrounding case or at a side position)), the inside of the light reflecting member 80 (along the surface of the halogen lamp 50), and the air outlet 107 of the airframe. A second duct 130 is formed by airflow communication between the air intake 106 of the fuselage, the duct of the heat sink 33, the duct of the fan (a duct formed by airflow communication between one (axial) vent of the fan, the cavity of the fan, and another vent of the fan (for example, in the fan surrounding case or at a side standing position)), the duct of the heat sink 82 of the light reflecting member, and the exhaust 107 of the fuselage. When the epilator 1000 is operating, the fan 90 draws air from the outside of the device through the air intake 106, and flows into the duct of the heat sink 33 to remove heat from the heat sink 33, thereby realizing heat dissipation by the hot surface of the semiconductor cooling element 10 and cooling by the cold surface. Airflow enters the cavity of the fan, one airflow passes through the vent of the fan (in the fan surrounding case or at the side position) and flows into the light reflecting element 80 to remove heat from the halogen lamp and the light reflecting element 80, and then flows out of the device through the exhaust port 107 of the housing, i.e., heat is dissipated from the halogen lamp 50 through the duct 110; at the same time, another airflow passes through the vent of the fan (in the fan surrounding case or at the side position) and flows into the duct of the light reflecting element heat sink 82 to remove heat, and then flows out of the device through the exhaust port 107 of the housing, i.e., heat is dissipated from the light reflecting element 80 through the second duct 130 and from the halogen lamp 50.
[0029] As shown in Figure 3, the epilator 1000 according to the second embodiment differs from the first embodiment in the heat dissipation principle in that it does not have a duct 110. The light source assembly in the second embodiment dissipates heat by air cooling through a second duct 130. The light reflecting member heat sink 82 in the second embodiment is attached in the opposite direction to that in the first embodiment, but is otherwise the same as or similar to the first embodiment.
[0030] As shown in Figures 4 and 5, the epilator 1000 according to the third embodiment differs from the first embodiment in that it does not have a second duct 130. The light source assembly in the third embodiment dissipates heat by air cooling through the duct 110. The third embodiment does not have a light source heat dissipation member. The rest of the configuration is the same as or similar to the first embodiment.
[0031] As shown in Figures 6 and 7, the light source assembly of the present invention generates parallel light and emits it as parallel light to the light exit window of the head of the epilator. The light source assembly mainly includes three optical elements: a halogen lamp 50, a light reflecting member 80, and a lens 60, which are designed to cooperate with each other to emit parallel light. The halogen lamp 50 is mounted within the light reflecting member 80, and the lens 60 is located outside the halogen lamp 50. The inner wall of the light reflecting member 80 has a parabolic inner wall 84. The halogen lamp 50, the parabolic inner wall 80 of the light reflecting member, and the lens 60 are designed as follows: The light path obtained is such that the light emitted from the halogen lamp 50 is reflected by the parabolic inner wall 84 of the light reflecting member or refracted by the lens 60, becoming a parallel beam of light. The parallel beam of light passes through the light exit of the light reflecting member and the light exit window 20 of the transparent body, and is irradiated onto the skin outside the light exit window 20 of the transparent body. Here, the cross-sectional shape of the parabolic inner wall 84 of the light reflecting member corresponds to a parallel light parabola, and the halogen lamp 50 is located at the focus F of the parallel light parabola, so that light emitted from the halogen lamp 50 is incident on the parabolic inner wall 84 and the reflected light is emitted along the direction of the central axis L of the parallel light parabola. In some embodiments, the parabolic inner wall 84 of the light reflecting member includes an upper parabolic inner wall and a lower parabolic inner wall corresponding to the parallel light parabola, the upper and lower parabolic inner walls being symmetrical with respect to the central axis L of the parallel light parabola and located above and below the halogen lamp 50, and a lens 60 is located in front of the halogen lamp 50 between the upper and lower parabolic inner walls, the height of the lens 60 matching the height of the halogen lamp 50. The upper and lower parabolic inner walls extend rearward to form corresponding parallel light parabolas. The distance between the ends of the upper parabolic inner wall and the lower parabolic inner wall corresponds to the height of the opening (light outlet) of the light reflecting member.
[0032] In another embodiment, the light reflecting member further includes upper and lower horizontal inner walls 85, which extend forward continuously from the upper and lower parabolic inner walls, respectively, and define a light exit passage within the light reflecting member between the upper and lower horizontal inner walls 85, with the front ends of the upper and lower horizontal inner walls being the light exit openings of the light reflecting member. The upper and lower horizontal inner walls are symmetrical with respect to the central axis L of the parallel light parabola and parallel to each other. Of the light rays generated from the halogen lamp 50, those emitted toward both sides by the upper and lower parabolic inner walls 84 are reflected and emitted in parallel along the central axis L, and those emitted to the lens 60 in the middle are refracted by the lens 60 and then emitted in parallel along the central axis L. As a result, the light rays generated from the halogen lamp 50 are reflected by the parabolic inner wall 84 of the light reflecting member and refracted by the lens 60 to form a concentrated parallel beam of light that is emitted to the light outlet along the light emission path inside the light reflecting member.
[0033] The inner wall of the light-reflecting member 80 includes a parabolic inner wall 84 (an upper parabolic inner wall and a lower parabolic inner wall; both indicated by 84) as a light-reflecting surface and a light-guiding surface. In this case, the overall shape of the light-reflecting member 80 may match the shape of the inner wall and have a uniform thickness. In other embodiments, the thickness of each portion of the light-reflecting member 80 may not match, and the outer contour of the light-reflecting member may not match the shape of its inner wall. The principle of the thickness and outer contour of the light-reflecting member corresponding to the horizontal inner wall 85 is the same. In the following embodiments, the structure of the light-reflecting member will be described using an example in which the thickness of each portion of the light-reflecting member 80 matches the overall contour of the light-reflecting member. That is, the contour of the inner wall of the light-reflecting member matches the overall contour of the light-reflecting member. Accordingly, the "parabolic inner wall" and "parabolic wall" are both indicated by the reference numeral 84, and the "horizontal inner wall" and "horizontal wall" are both indicated by the reference numeral 85.
[0034] The halogen lamp 50 includes a filament 53 and a transparent cover 54 (see FIGS. 7 and 8), and in this embodiment is designed as a cylindrical lamp tube (not limited to a cylindrical shape) with a predetermined length (matching the width w of the light reflecting member, see FIG. 1). Light generated from the filament is emitted through the transparent cover.
[0035] The light reflecting member 80 includes an arc-shaped (but not limited to arc-shaped) top wall 83 that conforms to the shape of the lamp tube to accommodate the rear of the halogen lamp. Parabolic (inner) walls 84 are continuously connected vertically to the front side of the top wall 83; that is, the upper and lower parabolic (inner) walls 84 extend forward and are connected to horizontal (inner) walls 85 (i.e., upper and lower horizontal (inner) walls), respectively. The top wall 83, parabolic wall 84, and horizontal wall 85 are preferably integral, smoothly connected, and extend forward. The upper parabolic wall 84 + upper horizontal wall 85 and the lower parabolic wall 84 + lower horizontal wall 85 are arranged vertically symmetrically with respect to the horizontal central axis L. The distance between the upper and lower horizontal walls 85 (or the opening distance between the upper and lower parabolic walls 84) corresponds to the height h of the opening (light outlet) of the light-reflecting member 80. The parabolic walls 84 and the horizontal walls 85 extend forward and connect to the side walls that form the light outlet passage. That is, a light outlet passage is formed inside the light-reflecting member, and the light outlet of the light-reflecting member is formed at the front end opening. The light-reflecting member may be closed or open along both left and right ends of its width w. If open, it can be used as a vent, allowing airflow to enter the light-reflecting member from one end and exit from the other end, removing heat from the surface of the halogen lamp and the interior of the light-reflecting member. The filament of the halogen lamp 50 is located at the focus F of the parabolic wall 84 of the light-reflecting member. For example, the cross section of the parabolic wall 84 is a parallel light parabola. The design principle of this parabola is shown in FIG. 7. In the XYZ coordinate system, the origin of the coordinate axes is the intersection of the directrix P of the parabola and the X coordinate axis (the horizontal central axis L of the light reflecting member), and the focus of the parabola is F, which is located on the X coordinate axis / horizontal central axis L of the light reflecting member. The distance of focus F from the directrix P is b. The coordinates of each point on the parallel light parabola are calculated based on the parallel light equation. X=5*T Y=sqrt(2*2*b*5T)=sqrt(20bT) Z=0 In the formula, X, Y, and Z respectively represent three-dimensional axis directions or coordinates, 5*T represents the X-direction variable in the parallel light parabolic equation (T is a variable related to the length of the parabola), b represents the distance between the focus F and the directrix P, which is the starting point (vertex) of the parabola. Q(b, 2a) is a point on the parabola, and b is determined based on the distance from the light outlet of the light source. For example, b is determined according to the required distance between the light source and the light outlet (or the head light outlet window of the epilator) during specific use. Once the position of the light source is determined, b is determined. In a non-limiting example, b = 1.5. The end point 841 of the parabolic wall 84 is determined by the height of the light-exiting opening (light outlet) of the light reflecting member, and the start point 840 of the parabolic wall 84 is determined by the height of the lamp tube of the halogen lamp 50. The height of the lens 60 corresponds to the height of the lamp tube of the halogen lamp 50, and its position is determined by the position of the focus F (filament). The lens 60 is perpendicular to the X-axis and is vertically symmetrical with respect to the X-axis. When light generated from the filament of the halogen lamp 50 is emitted forward (toward the light outlet), both incident rays i are emitted to the wall of the parallel light parabolic wall 84 to form totally reflected rays r. The totally reflected rays r are parallel to the horizontal central axis L (X-axis) of the light reflecting member 80, and the intermediate incident rays i are refracted by the lens 60 and emitted forward as horizontal rays parallel to the horizontal central axis L (X-axis). Therefore, after being reflected by the parallel light parabolic wall 84 or refracted by the lens 60, the light generated from the halogen lamp 50 is converted into a horizontally parallel beam of light and emitted to the opening (light outlet) along the light outlet path (located between the upper and lower horizontal walls 85 of the light reflecting member). The light is then filtered by the filter 70 at the opening (light outlet) of the light reflecting member before being emitted to the transparent light outlet window 20 of the head of the epilator and acting on the external skin to perform hair removal treatment.
[0036] The light source assembly of the present invention combines the parallel light parabolic (inner) wall 84 and lens 60 provided in the light reflecting member, so that the light generated from the light source becomes a parallel beam and is emitted to the light outlet along the light output path in the light reflecting member, thereby concentrating the emitted light of the halogen lamp, reducing the refraction of light within the light reflecting member and the loss of light energy, and enabling the emitted light to be concentrated and reach the light energy required for hair removal.
[0037] A filter 70 is provided at the opening (light outlet) at the front end of the light reflecting member, perpendicular to the light transmission direction. Light generated from the light source is emitted parallel to the light outlet along the light path, and filtered by the filter 70 to remove ultraviolet light, preventing damage to the skin surface and the user's eyes caused by ultraviolet light. The light generated by the halogen lamp 50 is nearly full spectrum and includes ultraviolet light. Ultraviolet light can damage the skin surface and eyes. When the epilator 1000 is in operation, the filter 70 can remove light waves below 500 nm or 480 nm, for example.
[0038] Examples of the configuration of a halogen lamp 50 are shown in Figures 8 and 9, but the configuration is not limited to these. As shown in Figure 8, the halogen lamp 50 has a cylindrical lamp tube and a cylindrical transparent cover 54. The filament extends along the left and right ends of the lamp tube in the longitudinal direction of the central axis, with both ends of the filament located at opposite ends in the longitudinal direction of the lamp tube and connected to electrodes 52, respectively. The electrodes 52 are electrically connected to electrode sheets 51 provided on the outside of both left and right ends of the lamp tube, and are thereby electrically connected to the main control board 100. As shown in Figure 9, the filament of the halogen lamp 50 is folded back along the longitudinal direction of the central axis, and isolating support members are provided in the central axis direction to support and separate the folded back filament. The both ends of the filament are located on the same side and are respectively connected to electrodes 52. The electrodes 52 are electrically connected to corresponding electrode sheets 51 provided on the outside of the same side of the lamp tube, and are electrically connected to the main control board 100 via the electrode sheets 51.
[0039] The power supply assembly includes a charging base 111 provided on the main control board 100, and the charging base 111 is electrically connected to a power line 105, which is used to connect to an external power source, such as a mobile power source or a commercial power source. The power supply assembly may further include a battery, such as a rechargeable battery.
[0040] The epilator 1000 according to some embodiments is provided with a semiconductor cooling member 10 at the head for cooling the light exit window 20 of the end face / transparent body, and the cold surface pre-cools or provides a cooling effect to the skin that comes into contact with the semiconductor cooling member 10. The semiconductor cooling member 10 may be provided around the light exit window 20 of the end face / transparent body to cool the periphery of the light exit window 20 of the transparent body, or it may be provided behind the light exit window 20 of the transparent body to provide a full cooling effect, or the cold surface of the semiconductor cooling member 10 can be directly used as the light exit window 20 of the transparent body to provide a full cooling effect.
[0041] The semiconductor cooling element 10, also known as a thermoelectric cooler (TEC), heat pump, or Peltier element, includes an intermediate semiconductor electric double layer 12, a hot surface 13 at each end, a cold surface 11, and a pair of positive and negative electrodes 120. The semiconductor cooling device further includes an internal or external temperature sensor. The positive and negative electrodes 120 and the temperature sensor are electrically connected to a main control board 100, an independent control board, or a main control unit to control the temperature of the cold or hot surface. The semiconductor electric double layer 12 is formed by alternating p-type and n-type semiconductor particles arranged parallel to each other and electrically connected in series. The hot surface 13 and the cold surface 11 formed at each end of the p-type and n-type semiconductor particles are thermally conductive material substrates, which may be, for example, ceramic, aluminum, copper, transparent materials, or the like, or may be heat pipes, VC, ALVC, or the like. The temperature sensor may be an NTC sensor 15.
[0042] In some embodiments, as shown in Figures 11-15, an NTC sensor 15, which is a temperature sensor, is disposed inside the semiconductor cooling member 10. The NTC sensor 15 is in close contact with the hot surface 13 / cold surface 11 of the semiconductor cooling member 10 to directly detect the temperature of the cold surface 11 / hot surface 13 of the cooling member.
[0043] 10, a first example of a semiconductor cooling device 10 has an annular shape and is attached to the rear of a transparent light exit window 20. A cold surface 11 cools the periphery of the transparent light exit window 20, achieving full-surface cooling. The central region of the annular semiconductor cooling member 10 forms a light-transmitting region 14. A parallel light beam generated by the light source assembly passes through the light-transmitting region 14 and the transparent light exit window 20 before being irradiated onto the skin in contact with the window, thereby hair removal. An NTC sensor 15 is disposed inside the semiconductor cooling member 10 and is in close contact with the hot surface 13 / cold surface 11 of the semiconductor cooling member 10 to directly detect the temperatures of the cold surface 11 / hot surface 13 of the cooling member, thereby achieving accurate temperature control.
[0044] As shown in FIG. 11 , in a second example of a semiconductor cooling device 10, the cooling surface 11 is used as a transparent light exit window 20. The semiconductor cooling device 10 may be provided with a light-transmitting region 14. Specifically, the cooling surface 11 may be made of transparent crystal, and the light-transmitting region 14 may be formed by the transparent crystal. The p-type and n-type semiconductor particles of the semiconductor electric double layer 12 may be arranged in a ring shape, with the ring-shaped intermediate region corresponding to the light-transmitting region. In this case, even when the heating surface 13 is made of a non-transparent material, it is also arranged in a ring shape, with the center of the ring corresponding to the light-transmitting region 14. When the heating surface is made of a transparent material, it is not limited to a ring shape, and the light-transmitting region 14 may be formed over the entire surface. The transparent crystal cooling surface 11 can cover the entire surface of the semiconductor electric double layer 12 to achieve full-surface cooling. The transparent crystal cooling surface 11 is the same material as the transparent light exit window 20 and is fixed by the front housing 102 of the epilator. A parallel light beam generated by the light source assembly is emitted from the transparent light exit window 20 and acts on the external skin to perform hair removal. The NTC sensor 15 is disposed inside the semiconductor cooling member 10, and the NTC sensor 15 is in close contact with the hot surface 13 / cold surface 11 of the semiconductor cooling member 10 to directly detect the temperature of the cold surface 11 / hot surface 13 of the cooling member, thereby realizing accurate temperature control.
[0045] In a second example, the thermal surface 13 is annular and may be a substrate made of a thermally conductive material (e.g., copper). In another example, the thermal surface 13 may be a heat pipe, a VC (Vapor Chamber, vapor chamber, or heat equalizer tube), or an ALVC (Aluminum Vapor Chamber, aluminum superconducting tube, or aluminum superconducting plate). In another example, the thermal surface 13 is directly a part of the outer wall of the thermally conductive member 31, and the thermally conductive member 31 may be an element made of a thermally conductive material (e.g., copper or aluminum), or a heat pipe, VC, or ALVC. In another example, when the thermally conductive member 31 is not provided inside the epilator 1000, the thermal surface 13 may be a part of the front end wall of the heat pipe 32.
[0046] In the third and fourth examples, as shown in FIGS. 12 and 13, a semiconductor cooling device 10 includes one transparent crystal cold surface 11 and hot surfaces 13 connected to one (FIG. 12) or multiple (two in FIG. 13) pairs of semiconductor electric double layers 12. The hot surfaces 13 connected to the one or multiple pairs of semiconductor electric double layers 12 are provided on one or multiple sides of the transparent crystal cold surface 11, and the other side of the transparent crystal cold surface 11 forms a light-transmitting area 14. The transparent crystal cold surface 11 is the same component as the transparent body light exit window 20. Parallel light generated by the light source assembly is emitted from the transparent crystal cold surface / transparent body light exit window 20 and acts on the external skin for hair removal. An NTC sensor 15 is located in the middle semiconductor electric double layer 12 (or in one or all of the semiconductor electric double layers) and is in close contact with the hot surface 13 / cold surface 11 of the semiconductor cooling element 10 to directly detect the temperature of the cold surface 11 / hot surface 13 of the cooling element, thereby achieving accurate temperature control.
[0047] In Examples 5 and 6, as shown in Figures 14 and 15, the entire cold surface 11 of the semiconductor cooling device 10 forms a cooling layer, the semiconductor electric double layer particles are spread flatly or almost flatly on the inner surfaces of the cold surface 11 and the hot surface 13, and the shapes of the cold surface 11 and the hot surface 13 are matched. The semiconductor electric double layer 12 and the NTC sensor 15 are located between the cold surface and the hot surface. The NTC sensor 15 is in close contact with the hot surface 13 or the cold surface 11. The positive and negative electrodes 150 of the NTC sensor 15 and the positive and negative electrodes 120 of the semiconductor electric double layer 12 extend outside the semiconductor cooling device 10 and are electrically connected to the main control board 100. The semiconductor cooling member 10 is respectively provided on one or more sides of the transparent light exit window 20, and the cold surface 11 is in close contact with the side surface of the transparent light exit window 20 to cool the transparent light exit window 20.
[0048] The operating principle of the semiconductor cooling device 10 is described below. The NTC sensor 15 of the semiconductor cooling element 10, which has a built-in NTC sensor, detects the temperature data of the cold surface 11 or hot surface 13 and transmits the temperature data to the main control unit on the main control board. The main control unit then analyzes the temperature data and outputs a control signal for the semiconductor cooling element according to the required temperature range, thereby controlling the power supply operation of the semiconductor cooling element 10. Taking advantage of the semiconductor cooling element's forward power supply cooling and reverse power supply heating characteristics, the semiconductor cooling element 10 is powered forward or reverse by an H-bridge drive to adjust the operating state of the semiconductor cooling element 10 and accurately maintain the temperature within the desired temperature range. An independent control board can be provided to control the operation of the semiconductor cooling device 10. The independent control board can be electrically connected to the main control board 100 of the epilator 1000, or the main control unit can be integrated into the main control board 100 of the epilator 1000.
[0049] The number of NTC sensors 15 may be one or more depending on the area and shape of the semiconductor cooling member.
[0050] When a temperature sensor is attached externally, it can be attached in close contact with the conductive member to detect the temperature. For example, the temperature sensor can be attached in close contact with the transparent light exit window 20 to detect the temperature of the end surface. The detected temperature information is transmitted to the main control unit, which compares it with a predetermined temperature and controls the power supply to the positive and negative poles of the semiconductor cooling member.
[0051] The epilator 1000 of the present invention uses a halogen lamp 50 as the light source. The light generated by the halogen lamp light source is not strong pulsed light, which does not harm or causes little damage to the eyes, does not require triggering at a high voltage of 8000V, is safer, and can be powered by low-voltage DC, making it smaller in size, less expensive to use, and causes little or no damage to the skin due to photothermal radiation, making it safer to use. The light generated by the halogen lamp light source is full-spectrum, allowing for more comprehensive use.
[0052] The light source assembly of the epilator 1000 of the present invention includes a convex lens and a light-reflecting member having a parabolic inner wall, which condenses the light beam from the halogen lamp, reduces the refraction of light within the light-reflecting member, and reduces energy loss.
[0053] In some embodiments of the epilator 1000, the end surface of the head (which comes into contact with the skin) is cooled by a semiconductor cooling element 10, and the temperature is precisely controlled by a built-in sensor to reach a constant temperature. In combination with the photothermal effect of a halogen lamp light source, the temperature of the skin surface to be epilated can be precisely controlled to a specific range, resulting in good epilation effect, without burning the skin, and without wasting energy.
[0054] In another embodiment, the filter 70 may be arranged to be detachably replaceable. For example, a slot may be provided for the filter 70 to be insertably and detachably replaced. Multiple filters 70 with different filter wavelength ranges may be arranged, and different filters 70 may be used depending on the device in which the epilator 1000 is used, capturing light waves in different wavelength bands and corresponding to different types of cosmetic or therapeutic functions. In another embodiment, multiple types of accessory heads may be externally attached to the head of the epilator, each equipped with a filter of a different wavelength band, thereby similarly realizing different cosmetic or therapeutic functions from the epilator itself. Alternatively, a single accessory head with switchable filters may be connected to the head of the epilator, similarly realizing different cosmetic or therapeutic functions. The ability to achieve multiple cosmetic or therapeutic functions with a halogen lamp epilator is primarily due to the halogen lamp generating full-spectrum light and the use of filters with different wavelength bands to obtain output light in specific wavelength bands.
[0055] Although embodiments of the present invention have been shown and described, those skilled in the art may make various changes, modifications, substitutions and variations to these embodiments without departing from the principles and spirit of the present invention, and all of these should fall within the scope of the present invention. The scope of protection of the present invention is limited by the appended claims and their equivalents.
