Referring to fig. 1 to 6, the present invention provides a depilatory apparatus 1000, the depilatory apparatus 1000 includes an outer housing 200, a light source assembly 300 is disposed in the outer housing 200, the light source assembly 300 includes a light source housing 310, a light source 320 and a reflective shade 330 accommodated in the light source housing 310, the light source housing 310 is provided with a light outlet window 3106, the light source 320 generates high intensity laser light under the action of current, and the reflective shade 330 is disposed on a side of the light source 320 facing away from the light outlet window 3106, for reflecting the laser light emitted by the light source 320 to the light outlet window 3106 for emitting, so as to burn skin hair of a human body to achieve a depilatory effect. Meanwhile, in order to ensure the intensity of light, the reflector 330 is configured into a U-shape, the light source 320 is in a lamp tube form, when the light source 320 works, part of light is directly emitted from the light emitting window 3106, and the light irradiated to the intrados of the U-shaped reflector 330 is concentrated and then emitted from the light emitting window 3106, so that the intensity of the light is effectively improved.

In order to prevent a human body from touching the light source 320 through the light outlet window 3106 and prevent external dust from entering the light source assembly 300 to cause burning odor, as shown in fig. 2, in the embodiment of the present invention, the light outlet window 3106 is provided with a transparent crystal 400, the transparent crystal 400 is made of a high-temperature resistant material, such as glass, precious stone, and other materials with good light transmission effect, and in this scheme, a sapphire crystal is preferably used, and the sapphire crystal is configured to be consistent with the shape of the light outlet window 3106 and is installed on the light outlet window 3106, so that at least part of the sapphire crystal is located on the light path of the light emitted by the light source assembly 300, thereby realizing light guiding, and preventing external matters from entering the light source assembly 300 from the light outlet window 3106.

As shown in fig. 2, in an embodiment of the present invention, another portion of sapphire is exposed from the outer housing 200 for contact with human skin. Meanwhile, in order to reduce the burning sensation of the high intensity light emitted from the sapphire to the skin of the human body, the epilator 1000 in the present embodiment further includes a cold compress assembly 100 to cool the sapphire, so that a cold compress area 410 is formed on the surface of the sapphire exposed from the outer housing 200.

As shown in fig. 4, in the embodiment of the present invention, specifically, the cold compress assembly 100 includes a semiconductor cooling plate 10 and a heat dissipation fan 30, after the semiconductor cooling plate 10 is powered on, the electronic negative electrode (-) starts from the semiconductor cooling plate 10, and first passes through the P-type semiconductor, absorbs heat to the N-type semiconductor, and emits heat, and each time passes through an NP module, heat is sent to the outside from one side to cause a temperature difference, so that the two surfaces of the semiconductor cooling plate 10 form a heating surface and a cooling surface. The cooling surface contacts a sidewall of the transparent crystal 400 to cool the transparent crystal 400, and it is understood that the semiconductor cooling sheet 10 may be mounted on a sidewall with a larger surface area of the transparent crystal 400 to enhance the cooling effect.

It will be appreciated that, in practical applications, the cold compress area 410 is not limited to the embodiment described above in which a portion of the surface of the sapphire extends out of the outer casing 200 for contact with the skin of a person. For example, in other embodiments of the present invention, an installation notch (not shown) may be formed in the outer housing 200 around the light emitting window 3106, and then a cold compress cover (not shown) with high heat conductivity may be installed, where one side of the cold compress cover extends into the outer housing 200. The manner in which the cold end of the semiconductor refrigeration sheet 10 is contacted and the other side is exposed to the outer shell 200 for contact with the skin of a user to form the cold compress region 410 is within the scope of the present invention.

Further, since sapphire is low in temperature in a state where the refrigerating surface of the semiconductor refrigerating sheet 10 is refrigerated, condensation of water mist is easily generated when it contacts with an external hot air flow. Therefore, as shown in fig. 2, in the present embodiment, the outer housing 200 is further provided with a flexible pad 800, and the flexible pad 800 covers the surface of a portion of the sapphire exposed to the outside, and is correspondingly provided with a light-transmitting area for emitting light. The flexible pad 800 may be made of transparent silica gel material, so as to isolate the direct contact of air flow between the outside and the sapphire, and avoid the generation of condensed water mist. Thereby avoiding the light from being deflected and weakened due to condensed water and aerosol.

In order to facilitate the installation of the flexible pad 800, a portion of the flexible pad body of the light-transmitting area where the flexible pad 800 is avoided is further provided with protruding connecting posts 810, for example, the flexible pads 800 located at two sides of the cold compress area are provided with protruding connecting posts 810, the outer shell 200 is provided with corresponding connecting blind holes (not labeled), two connecting posts 810 are inserted into the two connecting blind holes so that the flexible pad 800 is fixed to the outer shell 200, the outer shell 200 is provided with connecting blind holes so as to effectively prevent internal light from being emitted, and meanwhile, the flexible pad 800 is provided with protruding connecting posts 810 so as to strengthen the strength of the flexible pad 800. Preventing the flexible pad 800 from being detached from the outer case 200.

It should be understood that in practical application, the method of forming the connection protrusion 810 on the flexible pad 800 and the connection blind hole on the outer housing 200 is not limited to the above embodiment, for example, in other embodiments of the present invention, a glue method may be used, or a method of forming the connection blind hole on the flexible pad 800, a method of forming the connection protrusion on the outer housing 200 and extending the outer periphery of the flexible pad 800 along the shape of the outer housing, and a method of sleeving one end of the outer housing 200, where the light is emitted, are all within the scope of the present invention.

As shown in fig. 1, in the embodiment of the present invention, specifically, the surface of the outer casing 200 is provided with an air inlet 210 and an air outlet 220, the heat dissipation fan 30 is driven by current to draw external air flow into the outer casing 200 from the air inlet 210, and then exhaust the air through the air outlet 220, and the air inlet 210 and the air outlet 220 are formed by a plurality of small-aperture through holes on the surface of the outer casing 200, so as to effectively prevent external objects from being drawn into the outer casing 200 to damage internal components.

As shown in fig. 5, in the embodiment of the present invention, the heat dissipation frame 50 is specifically made of a metal material with high heat conduction efficiency, for example, copper, aluminum or copper-aluminum alloy, and in this technical solution, it is preferably made of aluminum for saving cost. The heat dissipation frame 50 includes integrally formed first, second and third portions 53, the first portion 51 is configured in a plate shape, and the area of the first portion 51 is larger than the area of the corresponding sidewall of the transparent crystal 400, so that the corresponding sidewall of the transparent crystal 400 is covered on the whole to achieve the maximum heat conduction area, and heat conduction is achieved through heat dissipation silica gel. The second portion 52 contacts the outer wall of the light source assembly 300, and the third portion 53 is located on the wind path of the heat radiation fan 30. When the heat of the first portion 51 and the second portion 52 is quickly transferred to the third portion 53, the heat of the third portion 53 is quickly transferred away by the air flow generated when the heat dissipation fan 30 works, so that the phenomenon of heat concentration is avoided.

Specifically, the number of the semiconductor cooling fins 10 may be two, the cooling surfaces of the two semiconductor cooling fins 10 may be in contact with the side wall of the light-transmitting crystal 400, and may be the same side wall, two adjacent side walls or two opposite side walls, which are not limited too much, and an additional portion (not shown) is extended from any one of the first, second or third portions of the heat dissipation frame 50 to be in contact with another semiconductor cooling fin (not shown) to achieve heat conduction, so that the manner of enhancing the cooling effect is also within the scope of the present invention.

As shown in fig. 5, in the embodiment of the present invention, specifically, the third portion 53 is constructed in a frame 531 shape, and a plurality of heat dissipation plates 532 disposed at intervals are constructed in the hollow portion of the frame 531. The first side wall of the frame 531 is connected to the second portion 52, and the third portion 53 is configured to have a larger size to enhance the heat dissipation surface area, so as to prevent the second and third side walls connected to the two ends of the first side wall from being thinner, which results in easy deformation of the third portion 53 during processing, so that the two ends of the plurality of heat dissipation plates 532 are respectively connected to the second and third side walls of the frame 531 and are configured to be parallel to the first side wall, thereby effectively enhancing the connection strength. Meanwhile, the heat dissipation surface area is effectively increased through the plurality of heat dissipation plates 532, and the heat dissipation efficiency is improved.

It should be understood that, in practical application, the third portion 53 is not limited to the above-mentioned heat dissipation plate 532 and the frame 531 being integrally and parallel to each other, for example, in other embodiments of the present disclosure, the third portion 53 may be configured as a grid or mesh, and the hollow portion of the grid or mesh forms an airflow channel for airflow to pass through. The way to achieve an increased heat dissipation surface area is also within the scope of the present invention. And will not be described in detail herein.

In order to effectively utilize wind energy of the heat dissipation fan 30 and reduce the occupied space, as shown in fig. 1, 2 or 4, in the embodiment of the present invention, the third portion 53 is located between the air suction end 31 of the heat dissipation fan 30 and the air inlet 210, when the heat dissipation fan 30 works, the external air flows into the air suction end 31 of the heat dissipation fan 30 after blowing and cooling the third portion 53 through the air inlet 210. Meanwhile, for easy installation, the frame 531 of the third portion 53 is fixed on the surface of the air suction end 31 of the heat dissipation fan 30 by the locking member 500, so that the frame 531 is tightly attached to the air suction end 31 of the heat dissipation fan 30, and thus the hollow part of the frame 531 is constructed into an air guide cavity which is communicated with the air passage of the air suction opening 311 of the air suction end 31, and meanwhile, the plurality of heat dissipation plates 532 are located in the air guide cavity and are erected on the air suction opening 311 of the heat dissipation fan 30, so that the air flow sucked by the heat dissipation fan 30 can be guaranteed to blow away and cool the plurality of heat dissipation plates 532 at high speed. Compared with the scheme of the traditional dehairing instrument 1000, the radiating structure is arranged at the downstream of the airflow of the radiating fan 30, the air outlet end 32 of the radiating fan 30 is connected with the radiating assembly through the constructed air duct, and the air flow is conducted through the longer air duct, so that wind energy loss is caused, a plurality of through holes of the air inlet 210 are matched to realize high-speed airflow impact, and the radiating efficiency is further improved. The locking member 500 may be one or more of a screw, a buckle, a connecting pin, etc., and in order to prevent the third portion 53 and the heat dissipation fan 30 from loosening due to the tiny vibration of the heat dissipation fan 30 during operation, the locking member 500 is a screw to lock the third portion 53 to the heat dissipation fan 30. Meanwhile, the third portion 53 can be effectively pressed against the heat radiation fan 30 by tightening the screwing force of the locking member 500.

Meanwhile, as shown in fig. 1 and fig. 2, in the embodiment of the present invention, a sealing ring 70 is further disposed on a surface of the frame 531 facing away from the heat dissipation fan 30, and two side surfaces of the sealing ring 70 are respectively sealed on the inner walls of the frame 531 and the outer housing 200 provided with the air inlet 210, so that the inner ring surface of the sealing ring 70 is configured to be the only air path communicating the air inlet 210 and the air guiding cavity, and the sealing ring 70 may be made of a material with elastic performance, such as silica gel, rubber, etc., so as to ensure the air path sealing effect.

Further, as shown in fig. 1 and fig. 2, in the embodiment of the present invention, the light source housing 310 is further provided with an air inlet window 3101 and an air outlet window 3102, a heat dissipation channel 3103 is formed between the air inlet window 3101 and the air outlet window 3102, the heat dissipation channel 3103 is communicated with the light source 320 and the reflector 330 in the light source housing 310, and the air flow discharged from the air outlet end 32 of the heat dissipation fan 30 flows into the heat dissipation channel 3103 through the air inlet window 3101, and when passing through the light source 320 and the reflector 330, the heat dissipated by the air flow is taken away, and then is discharged through the air outlet window 3102.

Further, as shown in fig. 1, in the embodiment of the present invention, the air outlet window 3102 is just right to the air outlet 220 of the outer housing 200, so as to prevent the hidden danger of heat concentration caused by the accumulation of hot air discharged from the air outlet window 3102 in the outer housing 200, and meanwhile, in order to prevent the light emitted by the light source 320 from being emitted from the air outlet window 3102 and damaging the outside, the light source 320 is isolated from the air outlet window 3102 by the light reflecting cover 330, in a specific isolation manner, the light source 320 is located in the U-shaped cavity of the U-shaped light reflecting cover 330, and the outer wall of the cambered surface of the light reflecting cover 330 and the inner wall of the light source housing 310 are arranged at intervals to form the heat dissipating channel 3103, so that the above phenomena are effectively prevented.

Meanwhile, as shown in fig. 1 to 4, in the embodiment of the present invention, in order to further save installation space, the air outlet end 32 of the heat dissipation fan 30 is inserted into the air inlet window 3101, without being connected through an air duct. So that the inner cavity of the outer casing 200 is free of a larger arrangement space from the direction of the connection line from the light source assembly 300 to the heat radiation fan 30, and a larger capacitor can be installed, thereby realizing high power output, and meanwhile, a built-in battery 700 is installed on one side of the heat radiation fan 30 far away from the light source assembly 300 and is used for supplying power to the light source assembly 300 and the cold compress assembly 100, so that the portable use is realized, an external power supply cable is not needed, and the applicable scene of the product is enhanced.

Specifically, as shown in fig. 1 and 3 in combination with fig. 5, in the embodiment of the present invention, the second portion 52 is constructed as a rectangular frame 521, and the frame 521 and the light source housing 310 are fastened using a locking member 500, such as a screw, to closely contact the frame 521 and the light source housing 310. Meanwhile, two side walls of the frame 521 are respectively connected with the first portion 51 and the third portion 53, a plurality of cooling fins 522 are constructed at the hollow position of the frame 521, and the plurality of cooling fins 522 are arranged at the hollow position of the frame 521 at intervals. Because the air outlet end 32 of the heat dissipation fan 30 is directly inserted into the air inlet window 3101 of the light source housing 310, the second portion 52 has a smaller size than the third portion 53, and has high connection strength, so as to ensure that the heat of the first portion 51 is rapidly conducted, the plurality of heat dissipation fins 522 are arranged at intervals in the hollow portion of the frame 521, and the two ends of the heat dissipation fins are respectively connected with the side wall of the frame 521 facing the first portion 51 and the side wall of the frame 521 facing the third portion 53, so that a plurality of heat conduction paths are established between the first portion 51 and the third portion 53 through a plurality of heat dissipation edges, and the heat dissipation efficiency of the first portion 51 is greatly improved.

It is to be understood that, in the practical application, the second portion 52 is not limited to the rectangular frame 521 in the above embodiment, for example, the second portion may also be circular, diamond-shaped, triangular, etc., which are all within the scope of the present invention, and will not be repeated herein.

Further, as shown in fig. 6, in the embodiment of the present invention, in order to accelerate the heat dissipation efficiency of the second portion 52, for convenience of description, the surface of the second portion 52 attached to the light source housing 310 is defined as a first surface 3104, in this technical solution, a portion of the air inlet window 3101 is exposed from the first surface 3104 to form an air guiding gap 3105, and at least a portion of the air flow discharged from the air outlet end 32 of the heat dissipation fan 30 flows from the air guiding gap 3105 to the second portion 52, so as to blow and cool the second portion 52.

Specifically, as shown in fig. 5, in the embodiment of the present invention, a side wall of the frame 521 connected to the third portion 53 is higher than the heat sink 522, so that a height difference between the side wall and the heat sink 522 forms an airflow channel 523, and meanwhile, a side wall of the frame 521 adjacent to the air guiding notch 3105 is further provided with an air passing opening to communicate with the airflow channel 523, so that the airflow discharged from the air inlet window 3101 blows on each heat sink 522 through the air guiding notch 3105 and the airflow channel 523, and further improves the heat dissipation efficiency.

Specifically, as shown in fig. 5, in the embodiment of the present invention, the side wall of the frame 521 connected to the third portion 53 is further provided with an air guide groove 5211 to communicate the air flow in the hollow space of the frame 521 to the hollow position of the frame 531 of the third portion 53, and when the cooling fan 30 is operated, the air suction force generated at the air inlet end can flow to the third portion 53 through the air guide groove 5211 and then be sucked into the cooling fan 30 from the air inlet end.

Specifically, as shown in fig. 5, in the embodiment of the present invention, the air guide groove 5211 is opened opposite to the connection portion between the heat dissipation plate 532 and the frame 531, and the plurality of heat dissipation plates 532 are each opened with an air passage 5321 communicating with the air guide groove 5211, so that the air flow extracted from the air guide groove 5211 can blow and dissipate heat from the plurality of heat dissipation plates 532 along the air passage 5321. Meanwhile, the connection part of the corresponding frame 531 and the heat dissipation plate 532 is provided, so that the position of the heat dissipation plate 532 erected on the edge of the heat dissipation fan 30 is effectively blown by air flow, and the phenomenon of heat concentration is prevented.

Further, as shown in fig. 1 and fig. 2, in the embodiment of the present invention, the second portion 52 is prevented from collecting air, and the outer housing 200 is further provided with an auxiliary air outlet 230, and the auxiliary air outlet 230 is formed by a plurality of small through holes, so that the air flow of the second portion 52 can be discharged through the auxiliary air outlet 230.

Further, as shown in fig. 1 and fig. 3, in the embodiment of the present invention, in order to prevent heat concentration inside the epilating apparatus 1000 and ensure stable operation of the epilating apparatus 1000, in the technical solution, the heat dissipation frame 50 further includes a fourth portion 54, where the fourth portion 54 is located at a side of the third portion 53 away from the third portion 53 and extends to cover a surface of the transformer 600 in the outer housing 200, so as to effectively transfer heat of the transformer 600 to the third portion 53, and prevent unstable operation caused by heat concentration of the transformer 600.

Specifically, in the embodiment of the present invention, the transformer 600 and the heat dissipation fan 30 are mounted on the same side of the circuit board (not identified), so as to save the mounting space, and the height of the transformer 600 is lower than that of the heat dissipation fan 30, so as to avoid the short circuit caused by the contact between the transformer 600 and the external components, and meanwhile, the fourth portion 54 is configured in a plate shape, and is connected to the frame 531 of the third portion 54 by using the inclined plate 55. Therefore, a heat dissipation cavity 551 is formed between the fourth portion 54 of the transformer 600 and the inner wall of the outer case 200, and the inclined plate 55 is disposed to make the space of the heat dissipation cavity 551 larger, so as to facilitate heat dissipation of the transformer 600. Meanwhile, the side wall of the frame 531 connected with the fourth portion 54 is further provided with an air guide gap 5322, and the inclined plate 55 is partially located at the bottom end of the air guide gap 5322, when the heat dissipation fan 30 works, air flow of the heat dissipation cavity 551 formed between the fourth portion 54 and the inner wall of the outer shell 200 is sucked into the air guide cavity from the air guide gap 5322, so that heat dissipation of the fourth portion 54 is accelerated.

Meanwhile, in order to ensure close adhesion between the fourth portion 54 and the transformer 600, a heat dissipation silica gel (not shown) is further coated between the fourth portion 54 and the transformer 600, so as to improve heat conductivity and avoid the phenomenon of low heat conduction efficiency caused by the virtual position. Meanwhile, a connecting post (not shown) is provided at the junction of the inclined plate 55 and the third portion 53, and is fixedly locked with the housing of the heat dissipation fan 30 by a locking member, so as to press the fourth portion 54 against the transformer 600.

Meanwhile, the transformer 600 is disposed close to the heat radiation fan 30 and is installed between the heat radiation fan 30 and the battery 700, preventing the long distance from causing the occupation of the arrangement space by the connection of the large-sized inclined plates 55 between the third and fourth parts 53 and 54 of the heat radiation frame. Meanwhile, the transformer 600 is arranged close to the heat dissipation fan 30, so that heat concentration points are all located on one side facing the heat dissipation fan 30, when the heat dissipation fan 30 works, hot air flow is sucked to the heat dissipation fan 30, and therefore heat generated by the transformer 600 cannot be conducted to the direction of the battery 700, and potential safety hazards caused by the fact that the battery 700 works in a high-temperature environment are effectively prevented.

Further, the battery 700 and the transformer 600 may be separated by a heat insulating filler (not shown), so as to prevent heat concentration, and the heat insulating filler may be made of porous material, such as foam, so that the air flow in the space accommodating the battery 700 may flow and heat dissipation may be accelerated when the heat dissipation fan 30 is operated.
