[0012] Currently, in existing hair removal devices with a single heat dissipation channel, due to the limitation of the size of the heat dissipation channel, the heat dissipation efficiency cannot be improved.

[0013] To solve the above problems, an embodiment of the present application provides a hair removal device. The hair removal device can be applied to the scenario of internal heat dissipation of the hair removal device. When the front cover of the bracket and the rear cover of the bracket are assembled, a first cavity for accommodating the lamp tube assembly is formed by enclosing the first connecting portion and the second connecting portion; 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, and 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 hole is provided in a first area of the first end surface of the rear cover of the bracket, and a first air inlet extends in a first direction around the first air inlet hole, and the first air inlet is connected to the air outlet of the fan on the fan; a first air outlet hole is further provided in a second area of the first end surface of the rear cover of the bracket, and a flow guiding portion is formed by extending in a first direction around the first air outlet hole, and the flow guiding portion is connected to the air outlet of the first housing; the length of the air outlet of the first housing along the width direction Y is greater than the length of the flow guiding portion along the width direction Y, and the length of the air outlet of the first housing along the height direction Z is greater than the length of the flow guiding portion along the height direction Z; the first air inlet, the first cavity and the flow guiding portion are communicated to guide the air blown out of the air outlet of the fan from the first air inlet to the first cavity, and then from the flow guiding portion to the air outlet of the first housing. In this way, the air outlet of the fan is closely connected to the first air inlet of the heat dissipation air duct in the light-emitting bracket, improving the sealing performance of the heat dissipation channel, reducing the air leakage rate, increasing the air pressure, and thus increasing the heat dissipation rate; in addition, the area of the air outlet of the first housing 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.

[0014] The specific structure of the hair removal device will be introduced in detail below.

[0015] Please refer to Figures 1 - 4, this application provides a hair removal device including a light-emitting component, a heat dissipation component, and a housing component; the light-emitting component includes a light-emitting bracket 100 and a lamp tube component 130, the heat dissipation component includes a fan 210, the housing component includes a first housing air outlet 350, and the light-emitting bracket 100 includes a front bracket cover 110 and a rear bracket cover 120; a first air inlet hole 1221 is formed in a first region 122 of a first end face 121 of the rear bracket cover 120, and a first air inlet 1222 extends forward in the positive direction of the width direction Y around the first air inlet hole 1221, and the first air inlet 1222 is connected to a fan 210 air outlet on the fan 210; a first air outlet hole 1231 is further formed in a second region 123 of the first end face 121 of the rear bracket cover 120, and a diversion portion 1232 is formed by extending forward in the positive direction of the width direction Y around the first air outlet hole 1231, and the diversion portion 1232 is connected to the first housing air outlet 350; the length of the first housing air outlet 350 in the width direction Y is greater than the length of the diversion portion 1232 in the width direction Y, and the length of the first housing air outlet 350 in the height direction Z is greater than the length of the diversion portion 1232 in the height direction Z; a first connection portion is provided on the front bracket cover 110, and a second connection portion 125 is provided on the rear bracket cover 120; in a state where the front bracket cover 110 and the rear bracket cover 120 are assembled, the first connection portion and the second connection portion 125 enclose a first cavity for accommodating the lamp tube component 130; the length of the first connection portion in the length direction X is greater than the length of the second connection portion 125 in the length direction X, and the length of the first connection portion in the height direction Z is greater than the length of the second connection portion 125 in the height direction Z; the first air inlet 1222, the first cavity, and the diversion portion 1232 are communicated, so that the air blown out from the fan 210 air outlet is guided from the first air inlet 1222 to the first cavity, and then guided from the diversion portion 1232 to the first housing air outlet 350. In this way, a first air inlet hole is provided on the rear bracket cover, and a first air inlet is formed by extending on the basis of the first air inlet hole, and then the fan air outlet is tightly connected to the first air inlet of the heat dissipation air duct in the light-emitting bracket, improving the sealing performance of the heat dissipation channel, reducing the air leakage rate, increasing the air pressure, and thus increasing the heat dissipation rate. At the same time, by providing the diversion portion, the area of the first housing air outlet is increased, thereby increasing the air volume and further enhancing the heat dissipation rate.

[0016] In a specific implementation, the hair removal device further includes a cold compress member 40 and a human body detection board 50. The front cover 110 of the bracket includes a light-emitting portion 111 and a first connecting portion. The light-emitting portion 111 is formed by connecting four first baffles to each other. The four first baffles enclose a first light-emitting through cavity 1112. The human body detection board 50 surrounds one end of the four first baffles (i.e., one end of the light-emitting through cavity), and one end of the human body detection board 50 abuts against one end of the four first baffles, and the other end of the human body detection board 50 abuts against the cold compress member 40. In this way, it is possible to detect whether the light-emitting port of the hair removal device touches the human skin through the human body detection board 50, and at the same time, when the lamp tube assembly 130 emits pulsed light, the pulsed light can be emitted through the light-emitting portion 111 and the cold compress member 40 in sequence.

[0017] Furthermore, the light-emitting assembly further includes a filter. The first connecting portion includes a base portion 1121. A third through hole 1122 is formed on the base portion 1121. The filter is disposed on the third through hole 1122 to block the third through hole 1122, thereby isolating the space of the first connecting portion from the first light-emitting through cavity 1112.

[0018] A first extension plate 1123 extends upward from the positive direction of the width direction Y of the first side of the base portion 1121, and a second extension plate 1124 extends upward from the positive direction of the width direction Y of the second side of the base portion 1121. The first side and the second side are opposite sides on the first connecting portion. At least one first engaging portion 1125 is respectively disposed on the first extension plate 1123 and the second extension plate 1124. Four second baffles 124 extend from the four sides of the first end face 121 of the rear cover 120 of the bracket in the reverse direction of the width direction Y to form a second connecting portion 125. At least one second engaging portion 1241 is respectively disposed on two of the four second baffles 124 in the height direction Z. When the front cover 110 of the bracket is assembled with the rear cover 120 of the bracket, the first engaging portion 1125 and the second engaging portion 1241 are engaged with each other, so that the first connecting portion and the second connecting portion 125 enclose a first cavity. The connection stability between the front cover 110 of the bracket and the rear cover 120 of the bracket is improved.

[0019] Please refer to Figure 3 and Figure 4 Take four first engaging portions 1125 and four second engaging portions 1241 as an example for illustration. The four first engaging portions 1125 are respectively disposed at the four corners of the first connecting portion, and the four second engaging portions 1241 are respectively disposed at the four corners of the second connecting portion 125. The positions of the four second engaging portions 1241 respectively correspond to the positions of the four first engaging portions 1125. In the assembled state of the front cover 110 of the bracket and the rear cover 120 of the bracket, the four second engaging portions 1241 are respectively engaged with the four first engaging portions 1125 to fix the front cover 110 of the bracket and the rear cover 120 of the bracket to each other.

[0020] In one example, at least one third engaging portion is provided on the air guide portion 1232, and at least one fourth engaging portion is provided on the air outlet 350 of the first housing; when the air outlet 350 of the first housing and the air guide portion 1232 are in an assembled state, the third engaging portion and the fourth engaging portion are engaged with each other, so that the air outlet 350 of the first housing and the air guide portion 1232 are fixed to each other. Through the engaging force between the third engaging portion and the fourth engaging portion, the engaging stability between the air outlet 350 of the first housing and the air guide portion 1232 is improved.

[0021] Exemplarily, structures such as a mortise and tenon structure, a screw assembly, and a snap structure may be provided between the first engaging portion 1125 and the second engaging portion 1241, and between the third engaging portion and the fourth engaging portion. The second engaging portion 1241 may be a structure adapted to the first engaging portion 1125, and the fourth engaging portion may be a structure adapted to the third engaging portion; for example, if the first engaging portion 1125 is a groove, the second engaging portion 1241 may be a protruding portion adapted to the groove, and if the first engaging portion 1125 is a protruding portion, the second engaging portion 1241 may be a groove adapted to the protruding portion; similarly, if the third engaging portion is a groove, the fourth engaging portion may be a protruding portion adapted to the groove, and if the third engaging portion is a protruding portion, the fourth engaging portion may be a groove adapted to the protruding portion. It can be understood that the shapes of the grooves or protruding portions of the first engaging portion 1125, the second engaging portion 1241, the third engaging portion, and the fourth engaging portion are only used for illustrative purposes here and are not limited.

[0022] In a possible example, please continue to refer to Figure 3 and Figure 4 , at least one fifth engaging portion 1126 is respectively provided on the first extension plate 1123 and the second extension plate 1124, and at least one sixth engaging portion 1242 is respectively provided on two of the four second baffles 124 in the height direction Z. When the front bracket cover 110 and the rear bracket cover 120 are assembled, the fifth engaging portion 1126 and the sixth engaging portion 1242 are engaged with each other, so that the first connecting portion and the second connecting portion 125 enclose to form a first cavity. The engaging stability between the front bracket cover 110 and the rear bracket cover 120 is improved.

[0023] It can be understood that the first engaging portion 1125, the second engaging portion 1241, the fifth engaging portion 1126, and the sixth engaging portion 1242 may exist simultaneously, and the combined action of the four engaging portions further improves the engaging stability between the front bracket cover 110 and the rear bracket cover 120.

[0024] For the accuracy of description, whenever directions are involved in this article, please uniformly use Figures 2 - 4For reference, the "length direction X" refers to the flow direction of the wind in the first cavity and the opposite direction of this flow direction, that is, the left-right direction (where the positive direction of the X-axis is to the right); the term "width direction Y" refers to the direction in which the front cover 110 of the bracket and the rear cover 120 of the bracket are combined with each other, that is, the Figure 3 front-back direction in Figure 2 (where the positive direction of the Y-axis is to the rear); the term "height direction Z" refers to the direction from the lower housing 12 to the upper housing 11 or from the upper housing 11 to the lower housing 12, that is, the

[0025] up-down direction in Figures 1 - 5 (where the positive direction of the Z-axis is upward). Among them, the length direction X, the width direction Y, and the height direction Z together constitute three orthogonal directions of the light-emitting bracket 100 (that is, the front cover 110 of the bracket and the rear cover 120 of the bracket). 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 the present application does not make specific limitations. For the convenience of description, the upper, lower, left, right, front, and rear directions in the present application are relative positions and do not constitute a limitation on implementation. Among them, the length direction X of the flow guiding portion 1232 and the first housing air outlet 350 is parallel to the length direction X of the light-emitting bracket 100, the width direction Y of the flow guiding portion 1232 and the first housing air outlet 350 is parallel to the width direction Y of the light-emitting bracket 100, and the height direction Z of the flow guiding portion 1232 and the first housing air outlet 350 is parallel to the height direction Z of the light-emitting bracket 100.

[0026] In a specific implementation, a first engaging portion 1125 is provided on each of the front and back sides of the first extension plate 1123 of the front cover 110 of the bracket in the longitudinal direction X. The first engaging portion 1125 faces downward in the height direction Z. At the same time, a first mating portion 113 is formed on the back surface of the first engaging portion 1125 (i.e., facing upward in the height direction Z), so that two fixing structures are formed at the same position. A fourth through hole 115 is provided in the first engaging portion 1125 on the left side in the longitudinal direction X. The first fixing portion 1321 of the first electrode 132 passes through the fourth through hole 115 and mates with the first mating portion 113 to fix the first electrode 132 to the front cover 110 of the bracket. Similarly, a fifth through hole 116 is provided in the first engaging portion 1125 on the right side in the longitudinal direction X. The third fixing portion 1331 of the second electrode 133 passes through the fifth through hole 116 and mates with the second mating portion 114 to fix the second electrode 133 to the front cover 110 of the bracket.

[0027] Exemplarily, the first fixing portion 1321 includes a first bending portion 1325 facing rightward in the longitudinal direction X. When the first fixing portion 1321 passes through the fourth through hole 115, it is combined with the first mating portion 113 through the first bending portion 1325. In this way, the first mating portion 113 can provide a supporting force for the first electrode 132, so that the first electrode 132 is hung on the front cover 110 of the bracket. Similarly, the third fixing portion 1331 includes a second bending portion 1335 facing leftward in the longitudinal direction X, and is combined with the second mating portion 114 through the second bending portion 1335. In this way, the second mating portion 114 can provide a supporting force for the second electrode 133, so that the second electrode 133 is hung on the front cover 110 of the bracket.

[0028] Further, a fifth fixing portion 1131 is provided on the first engaging portion 113, and a third engaging portion 1324 is provided on the first fixing portion 1321; when the first fixing portion 1321 is inserted through the first engaging portion 113, the third engaging portion 1324 is sleeved on the fifth fixing portion 1131; a sixth fixing portion 1141 is provided on the second engaging portion 114, and a fourth engaging portion 1334 is provided on the third fixing portion 1331; when the third fixing portion 1331 is inserted through the second engaging portion 114, the fourth engaging portion 1334 is sleeved on the sixth fixing portion 1141. Specifically, the third engaging portion 1324 is provided on the first bending portion 1325. When the third engaging portion 1324 is sleeved on the fifth fixing portion 1131, the displacement of the first electrode 132 can be further restricted, so that the first electrode 132 is more firmly fixed on the front cover 110 of the bracket. The fourth engaging portion 1334 is provided on the second bending portion 1335. When the fourth engaging 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 front cover 110 of the bracket.

[0029] Furthermore, a first limiting portion 1326 is provided on the first electrode 132. The first limiting portion 1326 extends from the first electrode 132 and abuts against the inner wall of the front cover 110 of the bracket, so as to limit the first electrode 132 on the first engaging portion 113; a second limiting portion 1336 is provided on the second electrode 133. The second limiting portion 1336 extends from the second electrode 133 and abuts against the inner wall of the front cover 110 of the bracket, so as to limit the second electrode 133 on the second engaging portion 114. In this way, a limiting structure is provided inside the front cover 110 of the bracket, so that after the first electrode 132 and the second electrode 133 are fixed, they cannot move from the inside of the front cover 110 of the bracket to the outside of the front cover 110 of the bracket (i.e., the positive direction of the height direction Z).

[0033] In a specific implementation, the number of the refrigerating members 240 can be one or more. When one refrigerating member 240 is provided, it can be a strip-shaped refrigerating member, and the refrigerating end of the strip-shaped refrigerating member abuts against the first end of the cold compress member 40 to cool the cold compress member 40; it can also be a ring-shaped refrigerating member, and the ring-shaped refrigerating member surrounds the outer cavity wall of the first light-emitting through cavity 1112, and at the same time the refrigerating end of the ring-shaped refrigerating member abuts against the first end of the cold compress member 40 to cool the cold compress member 40. When multiple refrigerating members 240 are provided, if the refrigerating members 240 are strip-shaped, then the multiple strip-shaped refrigerating members are respectively disposed around the outer cavity wall of the first light-emitting through cavity 1112, or the multiple strip-shaped refrigerating members are disposed on at least one side of the outer cavity wall of the first light-emitting through cavity 1112.

[0034] For example, in this embodiment, the cold compress member 40 is a sapphire sheet, and a step is provided on the sapphire sheet, and the cold compress member 40 abuts against the head cover 330 of the housing assembly through the step.

When the blower 210 is started, it sucks air from the air inlet of the housing, brings the heat on the heat dissipation fins into the blower 210, and then blows it out from the air outlet of the blower 210 into at least two heat dissipation channels. Taking the first heat dissipation channel and the second heat dissipation channel as an example, the blower 210 blows air to the first heat dissipation channel and the second heat dissipation channel; blows the heat of the lamp tube 131, the reflector 134 and the environment in the first heat dissipation channel in the first heat dissipation channel to the first channel air outlet, and discharges the hot air from the first housing air outlet 350 to achieve the purpose of heat dissipation; at the same time, blows the heat on the outer cup wall of the reflector 134 in the second heat dissipation channel to the second housing air outlet, and then discharges it outside the hair remover.

[0039] In addition, the housing assembly may further include a tail air inlet ( Figure 1(not shown in the figure), the tail air inlet is arranged at the tail of the hair remover housing composed of the upper housing 11 and the lower housing 12. When the fan 210 is started, air can also be introduced from the tail of the housing to suck the heat generated by components such as capacitors and chips in the first inner cavity of the hair remover into the fan 210.

[0040] In one example, please also refer to Figure 2 、 Figure 3 and Figure 7 . The heat dissipation component further includes a heat transfer member 250, which is arranged between the refrigerating member 240 and the main body 221 of the heat dissipation tube, and is used to transfer the heat at the heat generation end of the refrigerating member 240 to the heat dissipation tube 220; at least one seventh fixing portion 251 is arranged on the heat transfer member 250, and each seventh fixing portion 251 can be provided with at least two fixing members 2511. The first space restricted by the at least two fixing members 2511 is used to fix the refrigerating member 240. Since the shape of the heat transfer member 250 is sheet-like, the contact area with the refrigerating sheet is larger and the heat transfer efficiency is higher.

[0041] The heat transfer member 250 can be a copper metal member or other metal members, which are not limited herein.

[0042] Furthermore, at least one eighth fixing portion 252 is further arranged on the heat transfer member 250, and at least one ninth fixing portion 117 is arranged on the base 1121. For example, two eighth fixing portions 252 can be arranged, and the first ninth fixing portion 117 extends along the width direction Y in the first area 122 of the base 1121, and the second ninth fixing portion 117 extends along the width direction Y in the second area 123 of the base 1121. By combining the two eighth fixing portions 252 with the two ninth fixing portions 117, the heat transfer member 250 is fixed on the front cover 110 of the bracket. Furthermore, the combination method between the eighth fixing portion 252 and the ninth fixing portion 117 can be fixed by screws or other fixing methods, which are not limited herein.

[0043] It can be seen that in this embodiment, through the cooperation of the heat dissipation component, the heat generated by the refrigerating sheet, the heat generated by the lamp tube 131, and the heat in the first inner cavity are transferred to the air inlet of the fan 210, and then the fan 210 blows these heats into at least two heat dissipation channels, and discharges the heat out of the hair remover along the at least two heat dissipation channels. In this way, the heat is shunted through at least two heat dissipation channels, improving the heat dissipation efficiency.

[0044] In a possible embodiment, the hair remover further includes a main control module and a plurality of first refrigerating members, and the plurality of first refrigerating members are respectively electrically connected to the main control module; The main control module is used to perform the following operations: detecting the temperature rise rate of the cold compress part 40; determining a first gear according to the temperature rise rate; determining at least one second refrigeration part from the at least one first refrigeration part according to the first gear; and sending a first control instruction to the at least one second refrigeration part to control the at least one second refrigeration part to refrigerate the cold compress part 40.

[0045] In specific implementation, since the heat dissipation tube body 221 of the heat dissipation tube 220 is of a ring structure, two or more refrigeration parts 240 can be arranged around the ring structure to make full use of the contactable area of the heat dissipation tube body 221. After multiple refrigeration sheets are arranged, the corresponding refrigeration sheets can be controlled individually according to the refrigeration requirements.

[0046] Specifically, multiple control gears are set in advance according to the number of the refrigeration parts 240, and one control gear is set for each refrigeration part 240 or multiple refrigeration parts 240. Assuming that the refrigeration efficiency of each refrigeration part 240 is the same, multiple control gears can be divided according to the number of refrigeration sheets. The corresponding temperature rise rate range is set according to the refrigeration rate of each refrigeration part 240, and then each control gear is associated with the corresponding temperature rise rate range to form an association relationship of [control gear - temperature rise rate range - number of refrigeration parts 240].

[0047] When the hair remover starts to work, the temperature of the cold compress part 40 is detected to obtain the temperature information on the cold compress part 40; then, according to the obtained temperature information, the temperature rise situation of the cold compress part 40 per unit time is determined to obtain the corresponding temperature rise rate. The temperature rise rate range in which the temperature rise rate falls is determined, and then the corresponding first gear is determined according to the temperature rise rate range. The number of corresponding refrigeration parts 240 is determined according to the first gear, and then the corresponding number of second refrigeration parts is randomly selected from multiple first refrigeration parts according to the number of the refrigeration parts 240, and then a control signal is output to control the second refrigeration parts to refrigerate. Wherein, the first gear is one of the multiple control gears.

[0048] For example, assume that there are four refrigeration parts 240. If one refrigeration part 240 is taken as one control gear for division, there are four control gears, which are respectively recorded as the first control gear, the second control gear, the third control gear and the fourth control gear. The first control gear corresponds to the first temperature rise rate range and the first number of refrigeration parts, the second control gear corresponds to the second temperature rise rate range and the second number of refrigeration parts, the third control gear corresponds to the third temperature rise rate range and the third number of refrigeration parts, and the fourth control gear corresponds to the fourth temperature rise rate range and the fourth number of refrigeration parts.

[0049] If the detected temperature rise rate falls within the second temperature rise rate range, query the association relationship according to the second temperature rise rate range to determine the corresponding number of second refrigeration components. Randomly select the second refrigeration components corresponding to the number of second refrigeration components from multiple first refrigeration components, and then output a control signal to control the determined second refrigeration components to perform refrigeration.

[0050] It can be seen that in this embodiment, according to the temperature rise rate of the cold compress part 40, the number of refrigeration components 240 participating in refrigeration is controlled, so as to realize precise control of refrigeration, ensure the refrigeration efficiency and reduce the power consumption at the same time.

[0051] In a possible embodiment, the main control module is further configured to: determine a second gear from multiple preset wind speed gears according to the first gear; 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.

[0052] In specific implementation, since the refrigeration rate of each refrigeration component 240 is the same, therefore, the heat generation rate of each refrigeration component 240 during refrigeration is also the same. It can be seen from this that both the heat generation rate and the refrigeration rate are related to the number of refrigeration components 240, and the association relationship between the number of refrigeration components 240 - refrigeration rate - heat generation rate is obtained. In addition, the wind speed of the fan 210 is divided into multiple wind speed gears according to the heat dissipation rate of the fan 210, and the multiple wind speed gears correspond to multiple control gears one by one.

[0053] After completing the control of the refrigeration components 240, query the corresponding second gear from multiple wind speed gears according to the determined first gear. Then directly adjust the wind speed of the fan 210 according to the second gear to provide a heat dissipation rate adapted to the heat generation rate of the refrigeration components 240.

[0054] It can be understood that in practical applications, the heating elements in the hair removal device are not only the refrigeration components 240, but also the lamp tube 131, capacitors, chips and other heating elements. 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.

[0055] It can be understood that according to the determined first gear, the wind speed of the fan 210 is controlled, so as to realize precise control of refrigeration, ensure the refrigeration efficiency and reduce the power consumption at the same time.

Any person skilled in the art can easily think of changes or substitutions without departing from the spirit and scope of the present invention, and can make various changes and modifications, including the combination of the above different functions and implementation steps, including software and hardware implementation manners, all within the protection scope of the present invention.
