Description

Technical Field

[0001] This application relates to the field of beauty devices, and in particular to a hair removal device. Background Art

[0002] Existing hair removal devices use high-energy light sources such as pulsed light or laser to generate high-energy light to ablate hair. This high-energy light (or pulsed light / laser itself) can stimulate and harm the user's eyes, and can also cause harm to the skin or even burn the skin. Photothermal radiation causes great harm to the skin and is unsafe to use. Generating pulsed light or laser requires high voltage (such as a high voltage above 8000V) to trigger, and the use of such high voltage poses a safety hazard. Exciting pulsed light or laser requires specific components (such as a specific power supply or trigger mechanism), which results in a large body volume and high cost of the machine. Moreover, high-energy light sources consume a large amount of energy, which is not conducive to environmental protection. In addition, the spectral bands obtained by pulsed light and laser light sources are limited, and their use is not comprehensive. It is difficult for the main body of the machine to be used for beauty or treatment functions other than hair removal.

[0042] Refer to Figures 1-5, this application relates to a hair removal device 1000, which includes a housing and a light source assembly, a power supply assembly, and a main control board 100 installed inside the housing. The front end face of the head of the body forms a light exit window, and the end face at the light exit window can be directly in contact with the skin. As an embodiment, the light exit window on the front end face of the hair removal device 1000 is formed by a transparent body, and the transparent body light exit window 20 is fixed by an annular front shell 102. The light generated by the light source assembly is projected onto the transparent body light exit window to irradiate the external skin for hair removal treatment. The light source assembly, the power supply assembly, and the main control board 100 are electrically connected. The housing is provided with a plurality of ventilation openings, and the interior of the housing is a cavity. The plurality of ventilation openings provided in the housing include an air inlet 106 and an air outlet 107. A ventilation channel is formed inside the body, which is in air flow communication with the air inlet 106 and the air outlet 107. Ambient air or cold air enters the ventilation channel inside the body from the air inlet 106, takes away the heat of the heat-generating components, and is discharged outside the body from the air outlet 107 to achieve heat dissipation. It can be understood that the air inlet 106 and the air outlet 107 can be in various forms, such as the gap between the housings or one or more through holes provided on the housing, and can be provided on the same side or different sides of the housing, or the same ventilation opening or different ventilation openings can be used as the air inlet and the air outlet.

[0043] The housing includes a main housing 101 and a front shell 102 that are buckled to each other, and a cavity is formed inside the body. The front shell 102 is generally the housing at the front end of the head, but is not limited to the front end position, depending on the specific shape of the body. A lamp head bracket 40 is provided inside the body, and an internal bracket 103 can also be provided. The brackets 40 and 103 cooperate with the housing to install the various components of the hair removal device. The light source assembly is installed inside the front end of the body by the lamp head bracket 40; the fan 90, the radiator 33, and the main control board 100 are installed inside the main body of the body by the internal bracket 103 cooperating with the main housing 101. The main control board 100 is installed and protected in the cavity formed by the internal bracket 103 and the main housing 101 being buckled. A switch button 104 electrically connected to the main control board 100 is also installed on the housing, which is used for switch control or function setting, etc.

[0044] The lamp holder bracket 40 is arranged inside the front end of the body of the hair removal device 1000 and is used for installing the light source assembly. The light source assembly includes a halogen lamp 50, a reflector 80 for installing the halogen lamp 50, and a lens 60. The halogen lamp 50 is installed on the lamp holder bracket 40 by the reflector 80. An optical output channel is formed inside one side (front side) of the reflector 80. The end opening is the optical output port. The other side (rear side) of the reflector 80 is connected to a heat dissipation assembly for dissipating heat from the reflector 80. The heat dissipation assembly includes a heat conducting member 81 and / or a radiator 82. In the first embodiment, the reflector heat dissipation assembly includes a heat conducting member 81 and a radiator 82. The shape of the front side surface of the heat conducting member 81 is adapted to the shape of the rear side of the reflector 80 and they are mutually attached to perform rapid heat transfer; a radiator 82 is further arranged on the rear side of the heat conducting member 81. The radiator 82 includes a heat conducting substrate and one or more groups of heat dissipation fins. The radiator 82 can extend backward to the ventilation opening of the fan 90 to communicate with the air duct of the fan; and it is located in the ventilation channel inside the housing to facilitate heat dissipation of the light source. The rear side surface of the radiator 82 can be set to be arc-shaped and is adapted to the spiral rib circumference of the fan 90. The air flow in the fan cavity flows into the air duct of the radiator 82 from the fan ventilation opening and takes away heat. Both ends of the halogen lamp 50 are electrically connected to the main control board 100 through electrodes 51. A filter 70 is arranged in the optical path of the light source assembly and can be arranged at the optical output port of the reflector 80 to filter the light generated by the halogen lamp 50 to obtain an output light of a predetermined wavelength and project it onto the light output window of the head of the hair removal device to process the external skin.

[0045] The transparent light output window 20 on the front end surface of the head of the hair removal device 1000 in this application is fixed by the front shell 102. In some embodiments, the transparent body (such as a transparent crystal) forming the light output window can be cooled by a semiconductor refrigeration device 10, or the cold surface of the semiconductor refrigeration device can be directly used as the transparent light output window 20 to form an ice compress effect or a pre-cooling effect on the skin outside the transparent body. Due to the use of the semiconductor refrigeration device, a heat dissipation assembly needs to be configured inside the hair removal device 1000 to dissipate heat from the hot surface of the semiconductor refrigeration device 10. In other embodiments, the semiconductor refrigeration device 10 is used to cool the outer frame around the transparent light output window 20, and the outer frame contacts the skin to form an ice compress or pre-cooling effect on the skin.

[0046] Refer to Figures 1-2, which discloses a first embodiment of the hair removal device 1000 of the present application. Among them, the back surface of the transparent body is close to the cold surface of the annular thermoelectric cooling element 10, and the annular thermoelectric cooling element 10 is attached around the transparent body to achieve a full-surface cooling effect. The thermoelectric cooling element 10 includes a hot surface, a cold surface, and a semiconductor thermocouple layer in the middle, all of which are annular. For example, the heat dissipation component of the cooling element includes an annular heat conducting member 31, a heat pipe 32, and a radiator 33. Among them, the front end of the annular heat conducting member 31 is attached to the hot surface of the annular thermoelectric cooling element 10, and its rear end (back surface) is annularly attached to the front end of the heat pipe 32. The rear end of the heat pipe 32 is provided with a radiator 33 (for example, a group of heat sinks are inserted through the rear end of the heat pipe). The cold surface of the thermoelectric cooling element 10 cools the transparent body, and the heat of the thermoelectric cooling element 10 is transferred from the hot surface to the heat conducting member 31, and then transferred to the radiator 33 through the heat pipe 32 for heat dissipation, so that the cold surface is cooled.

[0047] In the first embodiment, one side of the radiator 33 of the cooling element (along the axis) is located behind the air inlet 106 of the housing, and the other side is a fan 90. The air duct of the radiator 33 corresponds to and communicates with the air inlet 106 and the (axial) ventilation opening of the fan 90. The air inlet 106 of the fuselage, the air duct of the radiator 33, the air duct of the fan 90 (the air duct formed by the air flow communication between an (axial) ventilation opening of the fan, the fan cavity, and another (such as a spiral rib or side-standing) ventilation opening of the fan), the inside of the light source reflector 80 (along the surface of the halogen lamp 50), and the air outlet 107 of the fuselage communicate with each other to form an air duct 110; the air inlet 106 of the fuselage, the air duct of the radiator 33, the air duct of the fan (the air duct formed by the air flow communication between an (axial) ventilation opening of the fan, the fan cavity, and another (such as a spiral rib or side-standing) ventilation opening of the fan), the air duct of the reflector radiator 82, and the air outlet 107 of the fuselage communicate with each other to form a second air duct 130. When the hair removal device 1000 works, under the action of the fan 90, the air outside the fuselage is sucked in from the air inlet 106, flows into the air duct of the radiator 33 to take away the heat of the radiator 33 to achieve heat dissipation of the hot surface of the thermoelectric cooling element 10 and cooling of the cold surface, and the air flow enters the fan cavity. One air flow flows into the light source reflector 80 through the (spiral rib or side-standing) ventilation opening of the fan to take away the heat of the halogen lamp and the reflector, and then flows out of the fuselage through the air outlet 107 of the housing, that is, the halogen lamp 50 is cooled by the air duct 110; at the same time, another air flow flows into the air duct of the reflector radiator 82 through the (spiral rib or side-standing) ventilation opening of the fan to take away the heat, and then flows out of the fuselage through the air outlet 107 of the housing, that is, the reflector 80 is cooled by the second air duct 130 so as to cool the halogen lamp 50.

[0048] The hair removal device 1000 of the second embodiment, refer to Figure 3, the difference in its heat dissipation principle from the first embodiment lies in that the air duct 110 is not provided; in the second embodiment, the light source assembly is air-cooled through the second air duct 130; in the second embodiment, the installation direction of the reflector radiator 82 is opposite to that in the first embodiment, and the others are the same as or similar to those in the first embodiment.

[0049] The hair removal device 1000 of the third embodiment, referring to Figures 4-5 , the difference in its heat dissipation principle from the first embodiment lies in that the second air duct 130 is not provided; in the third embodiment, the light source assembly is air-cooled through the air duct 110; in the third embodiment, the light source heat dissipation assembly is not provided, and the others are the same as or similar to those in the first embodiment.

[0050] Combined with reference to Figures 6-7 , the light source assembly of the present application generates parallel light and emits it towards the light output window of the hair removal device head as parallel light. The light source assembly mainly includes three optical elements: a halogen lamp 50, a reflector 80, and a lens 60, which are designed to cooperate with each other to emit parallel light. The halogen lamp 50 is installed inside the reflector 80, and the lens 60 is located outside the halogen lamp 50; the inner wall of the reflector 80 has a parabolic inner wall 84. The halogen lamp 50, the parabolic inner wall 80 of the reflector, and the lens 60 are designed to cooperate with each other to obtain the following light path: the light generated by the halogen lamp 50 forms a parallel light beam after being reflected by the parabolic inner wall 84 of the reflector or refracted by the lens 60, and the parallel light beam is emitted through the light output port of the reflector and the transparent body light output window 20 to irradiate the skin outside the transparent body light output window 20. Among them, the cross-sectional shape of the parabolic inner wall 84 of the reflector corresponds to a parallel light parabola; the halogen lamp 50 is located at the focus F of the parallel light parabola, so that the light generated by the halogen lamp 50 is incident on the parabolic inner wall 84, and its reflected light is emitted along the central axis L of the parallel light parabola. In some embodiments, the parabolic inner wall 84 of the reflector includes an upper parabolic inner wall and a lower parabolic inner wall corresponding to the parallel light parabola. The upper parabolic inner wall and the lower parabolic inner wall are symmetric about the central axis L of the parallel light parabola and are located on the upper and lower sides of the halogen lamp 50. The lens 60 is located in front of the halogen lamp 50 and between the upper parabolic inner wall and the lower parabolic inner wall; the height of the lens 60 is adapted to the height of the halogen lamp 50. The upper parabolic inner wall and the lower parabolic inner wall extend backward to form the corresponding parallel light parabola. 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 output port) of the reflector.

[0051] In other embodiments, the reflector further includes upper and lower horizontal inner walls 85; the upper horizontal inner wall and the lower horizontal inner wall respectively extend forward by continuing the upper parabolic inner wall and the lower parabolic inner wall, and a light-emitting channel inside the reflector is defined between the upper and lower horizontal inner walls 85; the front ends of the upper horizontal inner wall and the lower horizontal inner wall are the light-emitting ports of the reflector. The upper horizontal inner wall and the lower horizontal inner wall are symmetric with respect to the central axis L of the parallel light parabola and are parallel to each other. For the light generated by the halogen lamp 50, the light that is emitted to both sides and hits the upper and lower parabolic inner walls 84 is reflected, and the reflected light is emitted parallel along the central axis L; the light that is emitted to the middle and hits the lens 60 is refracted by the lens 60 and then emitted parallel along the central axis L. Thus, the light generated by the halogen lamp 50 forms a concentrated parallel light beam after being reflected by the parabolic inner wall 84 of the reflector and refracted by the lens 60, and is emitted out of the light-emitting port along the light-emitting channel inside the reflector.

[0052] The inner wall of the reflector 80 serves as a reflecting surface and a light guiding surface, and it includes a parabolic inner wall 84 (the upper parabolic inner wall and the lower parabolic inner wall, both marked as 84). At this time, the overall shape of the reflector 80 can be the same as the shape of the inner wall and has a uniform thickness. In other embodiments, the thickness of each part of the reflector 80 can be inconsistent, and then the outer contour of the reflector can be inconsistent with the shape of its inner wall. The principle of the thickness and the outer contour of the reflector corresponding to the horizontal inner wall 85 is the same. In the following embodiments, the structure of the reflector is described by taking the thickness of the reflector 80 as being consistent in various cases, that is, the contour of the inner wall of the reflector is the same as the overall contour of the reflector. Correspondingly, both the "parabolic inner wall" and the "parabolic wall" are represented by the label 84, and both the "horizontal inner wall" and the "horizontal wall" are represented by the label 85.

[0053] The halogen lamp 50 includes a filament 53 and a transparent lamp cover 54 (refer to Figures 7-8 ), and in this embodiment, it is designed as a cylindrical lamp tube shape (not limited to a cylindrical shape) and has a predetermined length (matched with the width of the reflector, refer to w ), refer to Figure 1 ). The light generated by the filament passes through the transparent lamp cover and is emitted.

[0054] The reflector 80 includes an arc-shaped (not limited to an arc-shaped) top wall 83, which is adapted to the shape of the lamp tube to accommodate the rear part of the halogen lamp. The front side of the top wall 83 is continuously connected to a parabolic (inner) wall 84 up and down, that is, the upper and lower parabolic (inner) walls 84 extend forward, and each is continuously connected to a horizontal (inner) wall 85 (that is, the upper and lower horizontal (inner) walls); the top wall 83, the parabolic wall 84, and the horizontal wall are preferably integrated and smoothly connected and extend forward. The upper parabolic wall 84 + the upper horizontal wall 85 and the lower parabolic wall 84 + the lower horizontal wall 85 are symmetrically arranged up and down with respect to the horizontal central axis L, and the distance between the upper and lower horizontal walls 85 (or the opening distance of the upper and lower parabolic walls 84) corresponds to the opening (light-emitting port) height of the reflector 80 h, the parabolic wall 84 and the horizontal wall 85 are connected and extend forward to form the side walls of the light-emitting channel, that is, the light-emitting channel is formed inside the reflector, and the front end opening forms the light-emitting port of the reflector. The reflector can be closed or not closed at the left and right ends along its width w . When not closed, it can be used as a ventilation port. The air flow enters the reflector from one end and flows out from the other end to take away the heat on the surface of the halogen lamp and inside the reflector. The filament of the halogen lamp 50 is arranged at the focus F of the parabolic wall 84 of the reflector. For example, the cross-section of the parabolic wall 84 is a parallel light parabola, and the design principle of this parabola refers to Figure 7 . In the XYZ coordinate system, the origin of the coordinate axes is the intersection point of the directrix P of the parabola and the X coordinate axis (the horizontal central axis L of the reflector). The focus of the parabola is F, and the focus F is located on the X coordinate axis / the horizontal central axis L of the reflector. The distance between the focus F and the directrix P is b. According to the parallel light equation, the coordinates of each point on the parallel light parabola are calculated as:

[0055] X = 5 * T

[0056] Y = sqrt(2 * 2 * b * 5T) = sqrt(20bT)

[0057] Z = 0

[0058] Wherein: X, Y, and Z respectively represent three-dimensional axes or coordinates; 5*T represents the variable in the X direction in the equation of the parallel light parabola (T is a variable related to the length of the parabola), and b represents the distance between the focus F and the directrix P; the directrix P is the starting point (vertex) of the parabola. Q(b, 2a) is a point on the parabola, and b is determined according to the distance between the light source and the light outlet, for example, b is determined according to the distance between the light source and the light outlet (or the light outlet window of the hair removal device head) during specific use. After the position of the light source is determined, b is determined; by way of non-limiting example, b = 1.5. The end point 841 of the parabolic wall 84 is determined by the height of the opening (light outlet) on the light-emitting side of the reflector, and the starting 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 is adapted 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 symmetrically arranged above and below the X-axis. When the light generated by the filament of the halogen lamp 50 is emitted forward (towards the light outlet), the incident light i on both sides is incident on the wall of the parallel light parabolic wall 84 to form total reflection light r. The total reflection light r is parallel to the horizontal central axis L (X-axis) of the reflector, and the incident light i in the middle is refracted by the lens 60 to be horizontal light and parallel to the horizontal central axis L (X-axis), and is emitted forward. Therefore, the light emitted by the halogen lamp 50 is all converted into a parallel light beam in the horizontal direction after being reflected by the parallel light parabolic wall 84 or refracted by the lens 60 and is emitted along the light outlet channel (between the upper and lower horizontal walls 85 of the reflector) towards the opening (light outlet), and then is filtered by the filter 70 at the opening (light outlet) of the reflector and is emitted towards the transparent body light outlet window 20 of the hair removal device head and acts on the external skin, so as to perform hair removal treatment on the skin.

[0059] The light source assembly of the present application cooperates with the lens 60 through the parallel light parabola (inner) wall 84 provided by the reflector, so that the light generated by the light source forms a parallel light beam and is emitted along the light outlet channel in the reflector towards the light outlet, making the emitted light of the halogen lamp concentrated, reducing the refraction of the light in the reflector, reducing the loss of light energy, and making the emitted light concentrated to reach the light energy required for hair removal.

[0060] A filter 70 is provided at the opening (light outlet) at the front end of the reflector, perpendicular to the light transmission direction. The light generated by the light source is parallel to the light outlet channel and is incident on the light outlet, and is filtered by the filter 70 to remove ultraviolet light to avoid damaging the skin surface or the user's eyes. The light generated by the halogen lamp 50 is close to the full spectrum and contains ultraviolet light. Ultraviolet light can cause damage to the skin surface and eyes. When the hair removal device 1000 is working, the filter 70 can be set, for example, to filter out light waves below 500 nm or 480 nm through the filter 70.

[0061] For an example of the structure of the halogen lamp 50, reference is made to Figures 8-9 , but is not limited to such a structure. Figure 8As shown, the cylindrical lamp tube of the halogen lamp 50 has a transparent lampshade 54 that is cylindrical. The filament is designed to extend to the left and right ends along the length direction of the central axis. The two ends of the filament are located at the opposite ends of the lamp tube length and are respectively connected to electrodes 52. The electrodes 52 are electrically connected to electrode plates 51 arranged outside the left and right ends of the lamp tube, and thus are electrically connected to the main control board 100. Figure 9 As shown, the filament of the halogen lamp 50 is arranged in a folded-back manner along the length direction of the central axis. An isolation support is arranged in the central axis direction to support and separate the folded-back filament. The two ends of the filament are located on the same side and are respectively connected to electrodes 52. The electrodes 52 are correspondingly electrically connected to two electrode plates 51 arranged outside the same side of the lamp tube, and are electrically connected to the main control board 100 through the electrode plates 51.

[0062] The power supply assembly includes a charging base 111 arranged on the main control board 100. The charging base 111 is electrically connected to a power cord 105, and the power cord 105 is used to connect to an external power supply such as a mobile power supply or mains electricity, etc. The power supply assembly may also include a battery, such as a rechargeable battery.

[0063] In some embodiments of the hair remover 1000, a semiconductor refrigeration component 10 is arranged at its head for cooling the end face / transparent body light-emitting window 20 to pre-cool the skin in surface contact or form an ice compress effect. The semiconductor refrigeration component 10 can be arranged around the end face / transparent body light-emitting window 20 to cool the periphery of the transparent body light-emitting window 20, or can be arranged behind the transparent body light-emitting window 20 to form an overall surface cooling effect. Or, or directly use the cold surface of the semiconductor refrigeration component 10 as the transparent body light-emitting window 20 to form an overall surface cooling effect.

[0064] The semiconductor refrigeration component, also known as the thermoelectric refrigeration component (Thermoelectric Cooler, TEC) or heat pump or Peltier cooler. It includes an intermediate semiconductor thermocouple layer 12 and a hot surface 13 and a cold surface 11 at both ends, and also includes a pair of positive and negative electrodes 120. The semiconductor refrigeration component also includes an internal or external temperature sensor. The positive and negative electrodes 120 and the temperature sensor are electrically connected to the main control board 100 or an independent control board or a main control unit to control the temperature of the cold surface or the hot surface. The semiconductor thermocouple layer 12 is formed by alternately placing p-type and n-type semiconductor particles parallel to each other and electrically connecting them in series. The hot surface 13 and the cold surface 11 formed at both ends of the p&n-type semiconductor particles are heat-conducting material substrates, such as ceramic / aluminum / copper / transparent body and other heat-conducting materials, or can also be heat pipes, VC, ALVC, etc. The temperature sensor can be an NTC sensor 15.

[0065] In some embodiments, refer to Figures 11-15, the temperature sensor, i.e., the NTC sensor 15, is placed within the semiconductor refrigeration component 10. The NTC sensor 15 is in contact with the hot surface 13 / cold surface 11 of the semiconductor refrigeration component 10 to directly detect the temperature of the cold surface 11 / hot surface 13 of the refrigeration component.

[0066] Refer to Figure 10 , in the first example of the semiconductor refrigeration component 10, its whole is annular and is attached behind the light-emitting window 20 of the transparent body. The cold surface 11 cools the periphery of the light-emitting window 20 of the transparent body to form a whole-surface cooling. A light-transmitting area 14 is formed in the central area of the annular semiconductor refrigeration component 10. The parallel light beam generated by the light source assembly passes through the light-transmitting area 14 and then passes through the light-emitting window 20 of the transparent body and irradiates the skin in contact with the outside of the window for hair removal treatment of the skin. The NTC sensor 15 is placed inside the semiconductor refrigeration component 10. The NTC sensor 15 is in contact with the hot surface 13 / cold surface 11 of the semiconductor refrigeration component 10 to directly detect the temperature of the cold surface 11 / hot surface 13 of the refrigeration component, achieving precise temperature control.

[0067] Refer to Figure 11 , in the second example of the semiconductor refrigeration component 10, its cold surface 11 directly serves as the light-emitting window 20 of the transparent body, and the semiconductor refrigeration component 10 can be provided with a light-transmitting area 14. Specifically, the cold surface 11 can adopt a transparent crystal, and the light-transmitting area 14 is formed by the transparent crystal. The p-type and n-type semiconductor particles of the semiconductor couple layer 12 can be arranged in a ring shape, and a light-transmitting area is correspondingly formed in the middle area of the ring. At this time, when the hot surface 13 adopts a non-transparent material, it is also correspondingly set in a ring shape, and the center of the ring corresponds to the light-transmitting area 14; when the hot surface also adopts a transparent material, it is not limited to a ring shape, and a light-transmitting area 14 can be formed on the whole surface. The whole surface of the transparent crystal cold surface 11 covering the semiconductor couple layer 12 can obtain whole-surface cooling. The transparent crystal cold surface 11 and the light-emitting window 20 of the transparent body are the same component and are fixed by the front shell 102 of the hair removal device. The parallel light beam generated by the light source assembly is emitted to and exits from the light-emitting window 20 of the transparent body to act on the external skin for hair removal treatment. The NTC sensor 15 is placed inside the semiconductor refrigeration component 10. The NTC sensor 15 is in contact with the hot surface 13 / cold surface 11 of the semiconductor refrigeration component 10 to directly detect the temperature of the cold surface 11 / hot surface 13 of the refrigeration component, achieving precise temperature control.

[0068] In the second example, the hot surface 13 is annular and can be a substrate made of a heat-conducting material (such as copper). In another embodiment, the hot surface 13 can be a heat pipe or a VC (Vapor Chamber, vapor chamber or vapor pipe) or an ALVC (Aluminum Vapor Chamber, aluminum super heat pipe or aluminum super heat plate). In another embodiment, the hot surface 13 is directly a part of the outer wall of the heat-conducting member 31, and the heat-conducting member 31 can be an element made of a heat-conducting material (such as copper or aluminum), or a heat pipe or a VC or an ALVC. In yet another example, when the heat-conducting member 31 is not provided inside the hair remover 1000, the hot surface 13 can be a part of the front end wall of the heat pipe 32.

[0069] In the third and fourth examples, referring to Figures 12-13 , the semiconductor refrigeration device 10 includes a transparent crystal cold surface 11 and a hot surface 13 connected by a group ( Figure 12 ) or multiple groups ( Figure 13 in this case, two groups) of semiconductor thermocouple layers 12; wherein, the hot surface 13 connected by one or multiple groups of semiconductor thermocouple layers 12 is disposed on one or more sides of the transparent crystal cold surface 11, and the other sides of the transparent crystal cold surface 11 form a light-transmitting area 14. The transparent crystal cold surface 11 and the transparent body light-emitting window 20 are the same component. The parallel light generated by the light source assembly is emitted to the transparent crystal cold surface / transparent body light-emitting window 20 and then emitted to perform hair removal treatment on the external skin. The NTC sensor 15 is located in the middle semiconductor thermocouple layer 12 (one of them or all semiconductor thermocouple layers), and is attached to the hot surface 13 / cold surface 11 of the semiconductor refrigeration device 10 to directly detect the temperature of the cold surface 11 / hot surface 13 of the refrigeration device, so as to achieve precise temperature control.

[0070] In the fifth - sixth examples, referring to Figures 14-15 , the entire cold surface 11 of the semiconductor refrigeration device 10 forms a full-surface refrigeration. The semiconductor thermocouple particles are laid flat or substantially laid flat on the inner surfaces of the cold surface 11 and the hot surface 13. The cold surface 11 and the hot surface 13 are adapted in shape. The semiconductor thermocouple layer 12 and the NTC sensor 15 are located between the cold surface and the hot surface. The NTC sensor 15 is attached to 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 thermocouple layer 12 extend out of the semiconductor refrigeration device 10 to be electrically connected to the main control board 100. The semiconductor refrigeration device 10 is respectively disposed on one or more sides of the transparent body light-emitting window 20, and its cold surface 11 is attached to the side surface of the transparent body light-emitting window 20 to cool the transparent body light-emitting window 20.

[0071] The working principle of the semiconductor refrigeration component 10 is as follows: For the semiconductor refrigeration component 10 with an internal NTC sensor 15, the NTC sensor 15 detects the temperature data of the cold surface 11 or the hot surface 13 and transmits the temperature data to the main control unit on the main control board; the main control unit controls the output of the control signal of the semiconductor refrigeration component through temperature data analysis and the requirements of a predetermined temperature range, thereby controlling the power supply operation of the semiconductor refrigeration component 10. Utilizing the characteristics of the semiconductor refrigeration component that it cools when powered forward and heats when powered backward, the semiconductor refrigeration component 10 is powered forward or backward through an H-bridge drive to adjust the working state of the semiconductor refrigeration component 10, so as to accurately maintain the temperature constant within the expected temperature range. An independent control board can be set to control the operation of the semiconductor refrigeration component 10, and the independent control board is electrically connected to the main control board 100 of the hair remover 1000; alternatively, the main control unit is integrated on the main control board 100 of the hair remover 1000.

[0072] The number of NTC sensors 15 can be set to one or more according to the area and shape of the semiconductor refrigeration component.

[0073] When the temperature sensor is externally placed, it can be attached to the component to be conducted to detect the temperature. For example, the temperature sensor is attached to the light output window 20 of the transparent body to detect the temperature of the end face, and the detected temperature information is transmitted to the main control unit. After comparing with the predetermined temperature, the power supply of the positive and negative electrodes of the semiconductor refrigeration component is controlled.

[0074] For the hair remover 1000 of the present application, its light source uses a halogen lamp 50. The light generated by the halogen lamp light source is non-intense pulsed light, which does not harm the eyes or causes little harm, does not require 8000V high-voltage triggering, is safer to use, can be powered by low-voltage direct current, so it has a smaller volume and lower usage cost. The light heat radiation causes little harm or no harm to the skin, and is safer to use; the light generated by the halogen lamp light source is in the full spectral band, and is more comprehensive to use.

[0075] For the hair remover 1000 of the present application, its light source assembly includes a convex lens and a reflector with a parabolic inner wall, which makes the halogen light rays concentrated and reduces the refraction of the light in the reflector; reduces energy loss.

[0076] For the hair remover 1000 in some embodiments, the end face of its head (in contact with the skin) is cooled by a semiconductor refrigeration component, and further uses the method of accurately controlling the temperature by an internal sensor to achieve constant temperature. Combining with the light heat effect of the halogen lamp light source, the temperature on the skin surface for hair removal can be accurately controlled within a certain temperature range, so that the hair removal effect is good, the skin will not be burned, and energy will not be wasted.

[0077] In other embodiments, the filter 70 may be configured to be detachably replaceable. For example, a slot may be provided to replace the filter 70 in a pluggable manner. Multiple filters 70 with different filter bands are configured. According to the main body of the hair removal device 1000 in use, different filters 70 are matched to obtain light waves of different bands, which are applied to different types of beauty or treatment functions. In another embodiment, by externally connecting a variety of accessory heads to the head of the hair removal device, each accessory head is equipped with a filter of a different band, and the same can also achieve different beauty or treatment functions by using the main body of the hair removal device. Alternatively, an accessory head with a switchable filter can be connected to the head of the hair removal device, and different beauty or treatment functions can also be achieved. The realization of multiple beauty or treatment functions by using a halogen lamp hair removal device is mainly due to the full spectrum generated by the halogen lamp. By cooperating with filters of different bands, the emitted light of a predetermined band is obtained.

[0078] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application, and all of them should belong to the scope of the present application; the protection scope of the present application is defined by the appended claims and their equivalent scope.
