[0021] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] Currently, the existing hair removal devices with a single heat dissipation channel are limited by the size of the heat dissipation channel, resulting in the inability to improve the heat dissipation efficiency.

[0023] To solve the above problem, an embodiment of the present application provides a hair removal device. The hair removal device can be used in scenarios where heat is dissipated inside the hair removal device. When the front cover of the bracket and the rear cover of the bracket are assembled, the first connecting portion and the second connecting portion enclose a first cavity for accommodating the lamp tube assembly; the length of the first connecting portion along the length direction X is greater than the length of the second connecting portion along the length direction X, The length of the first connecting portion along the height direction Z is greater than the length of the second connecting portion along the height direction Z; a first air inlet is provided in the first area of ​​the first end surface of the bracket back cover, and a first air inlet extends in the first direction around the first air inlet, and the first air inlet is connected to the fan outlet on the fan; a first air outlet is also provided in the second area of ​​the first end surface of the bracket back cover, and a guide portion is extended in the first direction around the first air outlet, and the guide portion is connected to the first shell air outlet; the length of the first shell air outlet along the width direction Y is greater than the length of the guide portion along the width direction Y, and the length of the first shell air outlet along the height direction Z is greater than the length of the guide portion along the height direction Z; the first air inlet, the first cavity and the guide portion are connected to guide the wind blown out of the fan outlet from the first air inlet to the first cavity, and then from the guide portion to the first shell air outlet. In this way, the fan outlet is tightly connected to the first air inlet of the heat dissipation duct in the light outlet bracket, improving the sealing of the heat dissipation duct, reducing air leakage, increasing wind pressure, and thus improving the heat dissipation rate. In addition, the area of ​​the first housing outlet is increased, thereby increasing the air volume and further enhancing the heat dissipation rate. This solution can be applied to a variety of scenarios, including but not limited to the application scenarios mentioned above.

[0024] The specific structure of the hair removal device is introduced in detail below.

[0025] See also Figure 1-Figure 4The present application provides a hair removal device including a light output component, a heat dissipation component and a shell component; the light output component includes a light output bracket 100 and a lamp tube component 130, the heat dissipation component includes a fan 210, the shell component includes a first shell air outlet 350, the light output bracket 100 includes a bracket front cover 110 and a bracket rear cover 120; the first end surface 121 of the bracket rear cover 120 has a first area 122 with a first air inlet 1221, and the air inlet 1221 is provided in a width direction around the first air inlet 1221. A first air inlet 1222 extends in the positive direction of the direction Y, and the first air inlet 1222 is connected to the air outlet of the fan 210 on the fan 210; the second area 123 of the first end surface 121 of the bracket back cover 120 is also provided with a first air outlet 1231, and a guide portion 1232 is formed around the first air outlet 1231 extending in the positive direction of the width direction Y, and the guide portion 1232 is connected to the first shell air outlet 350; the first shell air outlet 350 is connected to the first shell air outlet 350 along the width direction Y. The length is greater than the length of the guide part 1232 along the width direction Y, and the length of the first shell air outlet 350 along the height direction Z is greater than the length of the guide part 1232 along the height direction Z; a first connecting part is provided on the front cover 110 of the bracket, and a second connecting part 125 is provided on the rear cover 120 of the bracket; when the front cover 110 of the bracket and the rear cover 120 of the bracket are assembled, the first connecting part and the second connecting part 125 enclose a first cavity for accommodating the lamp tube assembly 130; the length of the first connecting part along the length direction X is greater than the length of the second connecting part 125 along the length direction X, and the length of the first connecting part along the height direction Z is greater than the length of the second connecting part 125 along the height direction Z; the first air inlet 1222, the first cavity and the guide part 1232 are connected to guide the wind blown out of the air outlet of the fan 210 from the first air inlet 1222 to the first cavity, and then from the guide part 1232 to the first shell air outlet 350. In this way, a first air inlet is provided on the rear cover of the bracket, and a first air inlet port is formed by extending the first air inlet port from the first air inlet port. The fan outlet is then tightly connected to the first air inlet port of the heat dissipation duct in the light outlet bracket. This improves the sealing of the heat dissipation duct, reduces air leakage, increases wind pressure, and thus improves the heat dissipation rate. Furthermore, the provision of the air guide increases the area of ​​the first housing outlet, thereby increasing the air volume and further enhancing the heat dissipation rate.

[0026] In a specific implementation, the hair removal device also includes a cold compress 40 and a human body detection plate 50. The bracket front cover 110 includes a light-emitting portion 111 and a first connecting portion. The light-emitting portion 111 is composed of four first baffles connected to each other. The four first baffles enclose a first light-emitting penetration cavity 1112. The human body detection plate 50 surrounds one end of the four first baffles (i.e., one end of the light-emitting penetration cavity), and one end of the human body detection plate 50 rests on one end of the four first baffles, while the other end of the human body detection plate 50 rests on the cold compress 40. In this way, the human body detection plate 50 can detect whether the light outlet of the hair removal device is in contact with human skin. At the same time, when the lamp tube assembly 130 emits pulsed light, the pulsed light can be emitted sequentially through the light-emitting portion 111 and the cold compress 40.

[0027] Furthermore, the light output component also includes a filter, the first connecting part includes a base 1121, and a third through hole 1122 is opened on the base 1121. The filter is arranged on the third through hole 1122 to block the third through hole 1122, thereby isolating the space of the first connecting part from the first light output penetration cavity 1112.

[0028] A first extension plate 1123 extends upward from a first side of the base portion 1121 in the positive width direction Y, and a second extension plate 1124 extends upward from a second side of the base portion 1121 in the positive width direction Y. The first side and the second side are opposite sides of the first connecting portion. At least one first coupling portion 1125 is provided on each of the first extension plate 1123 and the second extension plate 1124. Four second baffles 124 extend from four sides of the first end surface 121 of the bracket rear cover 120 in the opposite direction of the width direction Y to form the second connecting portion 125. Two of the four second baffles 124 in the height direction Z are each provided with at least one second coupling portion 1241. When the bracket front cover 110 and the bracket rear cover 120 are assembled, the first coupling portions 1125 and the second coupling portions 1241 engage with each other, enclosing the first connecting portion and the second connecting portion 125 to form a first cavity. This improves the secure connection between the bracket front cover 110 and the bracket rear cover 120.

[0029] See also Figure 3 and Figure 4 , the following description uses four first coupling portions 1125 and four second coupling portions 1241 as an example. The four first coupling portions 1125 are respectively located at the four corners of the first connecting portion, and the four second coupling portions 1241 are respectively located at the four corners of the second connecting portion 125. The positions of the four second coupling portions 1241 correspond to the positions of the four first coupling portions 1125. When the bracket front cover 110 and the bracket rear cover 120 are assembled, the four second coupling portions 1241 respectively couple with the four first coupling portions 1125, thereby securing the bracket front cover 110 and the bracket rear cover 120 to each other.

[0030] In one example, at least one third joint is provided on the air guide portion 1232, and at least one fourth joint is provided on the first housing air outlet 350. When the first housing air outlet 350 and the air guide portion 1232 are assembled, the third joint and the fourth joint engage with each other, thereby securing the first housing air outlet 350 to the air guide portion 1232. The bonding force between the third joint and the fourth joint enhances the secure connection between the first housing air outlet 350 and the air guide portion 1232.

[0031] For example, the first joint portion 1125 and the second joint portion 1241, as well as the third joint portion and the fourth joint portion, may be provided with a mortise and tenon structure, a screw assembly, a snap-fit ​​structure, or the like. The second joint portion 1241 may be a structure that matches the first joint portion 1125, and the fourth joint portion may be a structure that matches the third joint portion. For example, if the first joint portion 1125 is a groove, the second joint portion 1241 may be a protrusion that matches the groove, and if the first joint portion 1125 is a protrusion, the second joint portion 1241 may be a groove that matches the protrusion. Similarly, if the third joint portion is a groove, the fourth joint portion may be a protrusion that matches the groove, and if the third joint portion is a protrusion, the fourth joint portion may be a groove that matches the protrusion. It is understood that the shapes of the grooves or protrusions of the first joint portion 1125, the second joint portion 1241, the third joint portion, and the fourth joint portion are merely illustrative and not limiting.

[0032] In one possible example, see Figure 3 and Figure 4 At least one fifth coupling portion 1126 is provided on each of the first extension plate 1123 and the second extension plate 1124. At least one sixth coupling portion 1242 is provided on each of the two second baffles 124 in the height direction Z. When the front cover 110 and the rear cover 120 are assembled, the fifth coupling portion 1126 and the sixth coupling portion 1242 engage with each other, enclosing the first connecting portion and the second connecting portion 125 to form a first cavity. This improves the secure connection between the front cover 110 and the rear cover 120.

[0033] It can be understood that the first combining portion 1125 , the second combining portion 1241 , the fifth combining portion 1126 , and the sixth combining portion 1242 can exist at the same time. The combining action of the four combining portions further improves the combining stability of the bracket front cover 110 and the bracket rear cover 120 .

[0034] For the accuracy of description, please refer to the direction in this article. Figure 2-Figure 4For reference, the "length direction X" refers to the direction of wind flow in the first cavity and the opposite direction of the flow direction, that is, the left-right direction (where the positive direction of the X axis is right); the term "width direction Y" refers to the direction in which the bracket front cover 110 and the bracket rear cover 120 are connected to each other, that is, Figure 3 The front-to-back direction in the Y axis (where the positive direction of the Y axis is the rear); the term "height direction Z" refers to the direction from the lower shell 12 to the upper shell 11 or from the upper shell 11 to the lower shell 12, that is, Figure 2 The up and down directions (where the positive direction of the Z axis is upward), wherein the length direction X, the width direction Y and the height direction Z together constitute the three orthogonal directions of the light emitting bracket 100 (i.e., the bracket front cover 110 and the bracket back cover 120). The length direction X, the width direction Y and the height direction Z of the light emitting bracket 100 can be customized according to the specific structure of the product and the perspective presented in the drawings, and this application does not make specific restrictions. For the convenience of description, the directions such as up, down, left, right, front and back in this application are relative positions and do not constitute a limitation on the implementation. Among them, the length direction X of the air guide 1232 and the first shell air outlet 350 is parallel to the length direction X of the light emitting bracket 100, the width direction Y of the air guide 1232 and the first shell air outlet 350 is parallel to the width direction Y of the light emitting bracket 100, and the height direction Z of the air guide 1232 and the first shell air outlet 350 is parallel to the height direction Z of the light emitting bracket 100.

[0035] In one possible embodiment, see Figure 1-Figure 5 The lamp tube assembly 130 includes a first electrode 132, a second electrode 133 and a lamp tube 131. The first end of the first electrode 132 is provided with a first fixing portion 1321, and the bracket front cover 110 is provided with a first matching portion 113 adapted to the first fixing portion 1321; the first fixing portion 1321 is passed through the first matching portion 113, and a first electrical connection portion 1323 extends from the first fixing portion 1321 to the outside of the bracket front cover 110, and the first electrical connection portion 1323 is used to connect to the positive terminal of the power supply; the second end of the first electrode 132 is provided with a second fixing portion 1322, and the second fixing portion 132 2 is used to fix the positive terminal of the lamp tube 131; the first end of the second electrode 133 is provided with a third fixing portion 1331, and the bracket front cover 110 is provided with a second matching portion 114 adapted to the third fixing portion 1331; the third fixing portion 1331 is passed through the second matching portion 114, and a second electrical connection portion 1333 extends from the third fixing portion 1331 to the outside of the bracket front cover 110, and the second electrical connection portion 1333 is used to connect to the negative terminal of the power supply; the second end of the second electrode 133 is provided with a fourth fixing portion 1332, and the fourth fixing portion 1332 is used to fix the negative terminal of the lamp tube 131.

[0036] In a specific implementation, a first coupling portion 1125 is provided on both sides of the first extension plate 1123 in the longitudinal direction X. The first coupling portion 1125 faces downward in the height direction Z. A first mating portion 113 is formed on the back side of the first coupling portion 1125 (i.e., facing upward in the height direction Z), thereby forming two fixing structures in the same location. A fourth through-hole 115 is provided on the first coupling portion 1125 on the left side in the longitudinal direction X. The first fixing portion 1321 of the first electrode 132 passes through this fourth through-hole 115 and engages with the first mating portion 113 to secure the first electrode 132 to the bracket front cover 110. Similarly, a fifth through-hole 116 is provided on the first coupling portion 1125 on the right side in the longitudinal direction X. The third fixing portion 1331 of the second electrode 133 passes through this fifth through-hole 116 and engages with the second mating portion 114 to secure the second electrode 133 to the bracket front cover 110.

[0037] Illustratively, the first fixing portion 1321 includes a first bent portion 1325 oriented to the right in the longitudinal direction X. When the first fixing portion 1321 passes through the fourth through-hole 115, it engages with the first mating portion 113 via the first bent portion 1325. In this way, the first mating portion 113 can provide support for the first electrode 132, allowing the first electrode 132 to be suspended on the bracket front cover 110. Similarly, the third fixing portion 1331 includes a second bent portion 1335 oriented to the left in the longitudinal direction X. This second bent portion 1335 engages with the second mating portion 114. In this way, the second mating portion 114 can provide support for the second electrode 133, allowing the second electrode 133 to be suspended on the bracket front cover 110.

[0038] Furthermore, a fifth fixing portion 1131 is provided on the first matching portion 113, and a third matching portion 1324 is provided on the first fixing portion 1321; when the first fixing portion 1321 is inserted into the first matching portion 113, the third matching portion 1324 is sleeved onto the fifth fixing portion 1131. A sixth fixing portion 1141 is provided on the second matching portion 114, and a fourth matching portion 1334 is provided on the third fixing portion 1331; when the third fixing portion 1331 is inserted into the second matching portion 114, the fourth matching portion 1334 is sleeved onto the sixth fixing portion 1141. Specifically, the third matching portion 1324 is provided on the first bent portion 1325. When the third matching portion 1324 is sleeved onto the fifth fixing portion 1131, the displacement of the first electrode 132 is further limited, thereby more firmly fixing the first electrode 132 to the bracket front cover 110. A fourth matching portion 1334 is provided on the second bending portion 1335 . When the fourth matching portion 1334 is sleeved on the sixth fixing portion 1141 , the displacement of the second electrode 133 can be further restricted, so that the second electrode 133 is more firmly fixed on the bracket front cover 110 .

[0039] Furthermore, the first electrode 132 is provided with a first limiting portion 1326, which extends from the first electrode 132 and abuts against the inner wall of the bracket front cover 110, thereby limiting the first electrode 132 to the first mating portion 113. The second electrode 133 is provided with a second limiting portion 1336, which extends from the second electrode 133 and abuts against the inner wall of the bracket front cover 110, thereby limiting the second electrode 133 to the second mating portion 114. In this way, the limiting structure provided on the inner side of the bracket front cover 110 prevents the first electrode 132 and the second electrode 133 from moving from the inner side of the bracket front cover 110 to the outer side of the bracket front cover 110 (i.e., in the positive direction of the height direction Z) after being fixed.

[0040] In one possible embodiment, please refer to Figure 2 The light-emitting bracket 100 also includes a first connecting member 160, which is provided with a first penetrating cavity. The first air inlet 1222 is embedded in the first end opening of the first penetrating cavity, and the air outlet of the fan 210 is embedded in the second end opening of the first connecting member 160.

[0041] In specific implementation, such as Figure 2As shown, the first connecting member 160 is formed by connecting four third baffles, which enclose the first through-hole. The two ends of the opening of the first through-hole of the first connecting member 160 are respectively sleeved over the first air inlet 1222 and the air outlet of the fan 210, so that the first air inlet 1222 is embedded in the first end opening of the first through-hole, thereby improving the sealing between the first air inlet 1222 and the air outlet of the fan 210.

[0042] In one possible embodiment, please refer to Figure 2 The hair removal device also includes a cold compress 40, the heat dissipation assembly also includes a refrigeration component 240, the front cover of the bracket 110 also includes a light output portion 111, and the light output portion 111 includes a first light output penetration cavity 1112; the first end of the cold compress 40 abuts against the first end opening of the first light output penetration cavity 1112 of the light output portion 111, and the refrigeration component 240 abuts against the first end of the cold compress 40; the refrigeration component 240 surrounds the outer cavity wall of the first light output penetration cavity 1112, or the refrigeration component 240 is arranged on one side of the outer cavity wall of the first light output penetration cavity 1112.

[0043] In a specific implementation, the number of cooling elements 240 can be one or more. When one cooling element 240 is provided, it can be a strip cooling element, and the cooling end of the strip cooling element is placed against the first end of the cold compress 40 to cool the cold compress 40; it can also be an annular cooling element, and the annular cooling element is placed around the outer cavity wall of the first light-emitting penetrating cavity 1112, and the cooling end of the annular cooling element is placed against the first end of the cold compress 40 to cool the cold compress 40. When multiple cooling elements 240 are provided, if the cooling element 240 is strip-shaped, the multiple strip cooling elements are respectively placed around the outer cavity wall of the first light-emitting penetrating cavity 1112, or the multiple strip cooling elements are placed on at least one side of the outer cavity wall of the first light-emitting penetrating cavity 1112.

[0044] For example, in this embodiment, the cold compress 40 is a sapphire sheet with a step provided thereon, which abuts against the head cover 330 of the housing assembly. It is understood that the cold compress 40 can also be made of other materials or in other shapes, which are not limited here.

[0045] In one possible embodiment, see Figure 2 and Figure 6The heat dissipation component also includes a heat dissipation pipe 220 and a heat dissipation fin group 230; the heat dissipation pipe 220 includes a heat dissipation pipe body 221, which surrounds the outer wall of the second light outlet and rests against the heat-generating end of the refrigeration component 240, and the first branch pipe 222 and the second branch pipe 223 extend from the heat dissipation pipe body 221; the heat dissipation fin group 230 is provided with a first through hole 621 and a second through hole 622 that penetrates the heat dissipation fins in the heat dissipation fin group 230, the first branch pipe 222 is penetrated in the first through hole 621, and the second branch pipe 223 is penetrated in the second through hole 622, and the heat dissipation fins are arranged at the fan air inlet of the fan 210.

[0046] In a specific implementation, the heat dissipation assembly includes a refrigeration component 240, a heat dissipation pipe 220 and a heat dissipation fin group 230; the cooling end of the refrigeration component 240 rests on the cold compress component 40; the heat dissipation pipe body 221 of the heat dissipation pipe 220 is surrounded on the outer cavity wall of the first light-emitting penetration cavity 1112, and one end of the heat dissipation pipe body 221 rests on the heat-generating end of the refrigeration component 240, and at the same time, a first branch pipe 222 and a second branch pipe 223 extend from the heat dissipation pipe body 221; the heat dissipation fin group 230 is provided with a first through hole 621 and a second through hole 622 passing through each heat dissipation fin, the first branch pipe 222 is arranged in the first through hole 621, and the second branch pipe 223 is arranged in the second through hole 622, and the heat dissipation fins are arranged at the air inlet of the fan 210.

[0047] For example, the cooling element 240 may be in the shape of a ring, a bar, a rectangle, a cylinder, etc., which is not limited here.

[0048] In a specific implementation, the hair removal device also includes a main control board, which controls the cooling end of the refrigeration element 240 to start cooling to cool the cold compress element 40. At the same time, the heating end of the semiconductor refrigeration element 240 starts to release heat, transferring the heat to the heat pipe body 221. The heat is then transferred from the heat pipe 220 to the heat dissipation fin group 230 through the first branch pipe 222 and the second branch pipe 223. When the fan 210 is started, it draws air from the air inlet of the housing, brings the heat on the heat dissipation fins into the fan 210, and then blows the air from the fan 210 outlet to at least two heat dissipation channels. Taking the first heat dissipation channel and the second heat dissipation channel as an example, the air outlet of the fan 210 blows air to the first heat dissipation channel and the second heat dissipation channel; the heat in the lamp tube 131, the reflective cup 134 and the first heat dissipation channel environment in the first heat dissipation channel is blown to the first channel outlet, and the hot air is discharged from the first shell outlet 350 to achieve the purpose of heat dissipation; at the same time, the heat on the outer cup wall of the reflective cup 134 in the second heat dissipation channel is blown to the second shell outlet, and then discharged outside the hair removal device.

[0049] In addition, the housing assembly may further include a rear air inlet ( Figure 1(not shown), the rear air inlet is arranged at the rear of the hair removal device housing composed of the upper housing 11 and the lower housing 12. When the fan 210 is started, air can also be taken in from the rear of the housing to absorb the heat generated by the capacitor, chip and other components in the first inner cavity of the hair removal device into the fan 210.

[0050] For an example, see also Figure 2 、 Figure 3 and Figure 7 The heat dissipation assembly further includes a heat transfer member 250, disposed between the cooling element 240 and the heat pipe body 221, for transferring heat from the heat-generating end of the cooling element 240 to the heat pipe 220. The heat transfer member 250 is provided with at least one seventh fixing portion 251. Each seventh fixing portion 251 can be provided with at least two fixing members 2511. The first space defined by the at least two fixing members 2511 is used to secure the cooling element 240. Due to the sheet-like shape of the heat transfer member 250, the contact area with the cooling element 240 is larger, resulting in higher heat transfer efficiency.

[0051] The heat transfer element 250 may be a copper metal element, or other metal elements, which are not limited here.

[0052] Furthermore, the heat transfer member 250 is provided with at least one eighth fixing portion 252, and the base portion 1121 is provided with at least one ninth fixing portion 117. For example, two eighth fixing portions 252 may be provided, with a first ninth fixing portion 117 extending from the first region 122 of the base portion 1121 along the width direction Y, and a second ninth fixing portion 117 extending from the second region 123 of the base portion 1121 along the width direction Y. The two eighth fixing portions 252 are combined with the two ninth fixing portions 117 to secure the heat transfer member 250 to the bracket front cover 110. Furthermore, the eighth fixing portion 252 and the ninth fixing portion 117 may be combined by screws or other fixing methods, which are not limited herein.

[0053] As can be seen, in this embodiment, the heat generated by the cooling element 240, the heat generated by the lamp 131, and the heat in the first inner cavity are transferred to the air inlet of the fan 210 through the cooperation of the heat dissipation assembly. The fan 210 then blows this heat into at least two heat dissipation channels, and the heat is discharged outside the hair removal device along the at least two heat dissipation channels. In this way, the heat is divided through at least two heat dissipation channels, thereby improving the heat dissipation efficiency.

[0054] In a possible embodiment, the hair removal device further includes a main control module and a plurality of first refrigeration components, and the plurality of first refrigeration components are electrically connected to the main control module respectively;

[0055] The main control module is used to perform the following operations: detect the temperature rise rate of the cold compress 40; determine a first gear according to the temperature rise rate; determine at least one second refrigeration component from the at least one first refrigeration component according to the first gear; and send a first control instruction to the at least one second refrigeration component to control the at least one second refrigeration component to cool the cold compress 40.

[0056] In a specific implementation, since the heat pipe body 221 of the heat pipe 220 is annular in structure, two or more cooling elements 240 can be arranged around the annular structure to fully utilize the contact area of ​​the heat pipe body 221. After multiple cooling elements 240 are arranged, the corresponding cooling elements 240 can be individually controlled to perform cooling according to cooling requirements.

[0057] Specifically, multiple control levels are pre-set based on the number of refrigeration elements 240, with one control level set for each refrigeration element 240 or multiple refrigeration elements 240. Assuming that each refrigeration element 240 has the same cooling efficiency, multiple control levels can be set based on the number of refrigeration elements 240. A corresponding temperature rise rate range is set based on the cooling rate of each refrigeration element 240, and each control level is then associated with the corresponding temperature rise rate range, forming an association relationship of [control level - temperature rise rate range - number of refrigeration elements 240].

[0058] When the hair removal device starts working, it starts to detect the temperature of the cold compress 40 to obtain the temperature information on the cold compress 40; then, based on the obtained temperature information, it determines the temperature rise of the cold compress 40 per unit time to obtain the corresponding temperature rise rate. It determines the temperature rise rate range that the temperature rise rate falls into, and then determines the corresponding first gear according to the temperature rise rate range. The number of corresponding refrigeration components 240 is determined according to the first gear, and then, based on the number of refrigeration components 240, a corresponding number of second refrigeration components are randomly selected from multiple first refrigeration components, and then a control signal is output to control the second refrigeration components to perform cooling. Among them, the first gear is one of multiple control gears.

[0059] For example, assuming there are four refrigeration elements 240, and each refrigeration element 240 is divided into one control level, there are four control levels, namely the first control level, the second control level, the third control level, and the fourth control level. The first control level corresponds to the first temperature rise rate range and the first number of refrigeration elements, the second control level corresponds to the second temperature rise rate range and the second number of refrigeration elements, the third control level corresponds to the third temperature rise rate range and the third number of refrigeration elements, and the fourth control level corresponds to the fourth temperature rise rate range and the fourth number of refrigeration elements.

[0060] If the detected temperature rise rate falls within a second temperature rise rate range, a correlation relationship is queried based on the second temperature rise rate range to determine the corresponding number of second refrigeration components. Based on the second number of refrigeration components, second refrigeration components corresponding to the second number of refrigeration components are randomly selected from multiple first refrigeration components, and a control signal is output to control the determined second refrigeration components to perform cooling.

[0061] It can be seen that in this embodiment, the number of cooling elements 240 participating in cooling is controlled according to the temperature rise rate of the cooling element 40, thereby achieving precise control of cooling, ensuring cooling efficiency while reducing power consumption.

[0062] In a possible embodiment, the main control module is further used to: determine a second gear from multiple preset wind speed gears according to the first gear; and send a second control instruction to the fan 210 according to the second gear to control the fan 210 to dissipate heat according to the second control instruction.

[0063] In a specific implementation, since each refrigeration element 240 has a consistent cooling rate, the heat generation rate of each refrigeration element 240 during cooling is also consistent. Therefore, it can be seen that both the heat generation rate and the cooling rate are related to the number of refrigeration elements 240, resulting in a correlation between the number of refrigeration elements 240, the cooling rate, and the heat generation rate. Furthermore, the wind speed of the fan 210 is divided into multiple wind speed levels based on the heat dissipation rate of the fan 210, and the multiple wind speed levels correspond to the multiple control levels.

[0064] After completing the control of the refrigeration element 240, the corresponding second gear is searched from the plurality of wind speed gears according to the determined first gear. Then, the wind speed of the fan 210 is directly adjusted according to the second gear to provide a heat dissipation rate adapted to the heat generation rate of the refrigeration element 240.

[0065] It is understandable that in actual applications, the heating element in the hair removal device is not only the refrigeration element 240, but also includes the lamp 131, capacitors, chips, etc. In order to ensure that the heat dissipation requirements can be met, the heat dissipation rate that can be achieved by the wind speed corresponding to the second gear can be greater than the heat generation rate corresponding to the first gear.

[0066] It is understandable that the wind speed of the fan 210 is controlled according to the determined first gear, thereby achieving precise control of cooling, ensuring cooling efficiency while reducing power consumption.

Any person skilled in the art may readily conceive of variations or substitutions, and may make various modifications and alterations without departing from the spirit and scope of the present invention. Combinations of the above-described functions and implementation steps, including software and hardware implementations, are all within the scope of protection of the present invention.
