Description

Technical Field

[0001] The present invention belongs to the technical field of beauty equipment, and in particular relates to a hair removal device. Background Art

[0002] Epilators are instruments used to remove body hair. Home-use hair removal devices are increasingly popular among consumers due to their ease of use and simplicity. Because hair removal devices utilize a lamp that emits light of a specific wavelength to destroy hair follicles, they generate significant heat during the process, causing a burning sensation in the area being treated. Therefore, timely cooling of the area is necessary to alleviate user discomfort.

[0003] Chinese invention patent application number CN202010609339.7 discloses a hair removal device, which includes: a heat conduction plate having a main heat absorption portion, a primary heat absorption portion, a secondary heat absorption portion, and a heat output portion, wherein the main heat absorption portion, the primary heat absorption portion, and the secondary heat absorption portion are all connected to the heat output portion to transfer the heat absorbed by themselves to the heat output portion, which then outputs the heat; a cold compress portion, one side of which is attached to the main heat absorption portion to transfer its own heat to the main heat absorption portion to achieve cooling, and the other side of which is attached to the user's skin to apply a cold compress to the user's skin; a hair removal device fixed to one side of the cold compress portion to emit light passing through the cold compress portion; a control device including a processor and a capacitor, which are attached to the first heat absorption portion and the second heat absorption portion, respectively, to transfer their own heat to the first heat absorption portion and the second heat absorption portion; and a heat dissipation portion attached to the heat output portion to dissipate heat from the heat output portion. The overall temperature of the hair removal device can be effectively reduced. However, this patent only uses a single-piece refrigeration component to cooperate with a cold compress component, which makes the heat dissipation of the cold compress component uneven, and the air convection heat dissipation is not timely, which will cause the temperature of the heat dissipation port to fail to drop, and the expected cooling effect cannot be achieved, causing a burning pain to the user. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a hair removal device with good heat dissipation performance, significant cooling effect and no burning pain during use.

[0005] To achieve the above purpose, the specific technical solutions of the present invention are as follows:

[0006] A hair removal device, comprising a hair removal device body, a cold compress device provided at a working end of the hair removal device body, a hair removal device installed on one side of the cold compress device within the hair removal device body, a heat dissipation device for dissipating heat from the cold compress device, and a cold drive device for cooling the heat dissipation device, wherein the heat dissipation device comprises a first heat dissipation component and a second heat dissipation component;

[0007] The first heat dissipation assembly includes a first cooling fin, a first heat dissipation plate and a first fin group, wherein the first cooling fin and the first fin group are installed at intervals on the lower end surface of the first heat dissipation plate;

[0008] The second heat dissipation assembly includes a second cooling fin, a second heat dissipation plate, and a second fin group, wherein the second cooling fin and the second fin group are installed at intervals on the upper end surface of the second heat dissipation plate;

[0009] The cold compress device comprises a plurality of interconnected cold compress blocks, each of which comprises a substrate, the substrate comprising two light-transmissive end surfaces, and a side surface between two adjacent substrates is coated with a first heat-conducting layer;

[0010] The first cooling fin is in contact with the upper end surface of the cold compress device, the second cooling fin is in contact with the lower end surface of the cold compress device, and the first cooling fin and the second cooling fin are both connected to the first heat conductive layer. The cold compress device, the first heat dissipation component and the second heat dissipation component together form an installation space for the hair removal device, and the cold drive device is used to cool the first fin group and the second fin group.

[0011] Therefore, the present application sets a plurality of cold compress blocks and uses the first heat-conducting layer to cool down each cold compress block individually, thereby evenly cooling down the entire cold compress device. The cold compress device of the present application not only cools down quickly, but also avoids skin burns caused by dead corners caused by uneven cooling of the cold compress parts. At the same time, the present application sets heat dissipation components on the upper and lower end surfaces of the cold compress device, so that the upper and lower end surfaces of the cold compress device can both perform passive heat dissipation. The cooling fins on the upper and lower end surfaces can quickly take away the heat of the cold compress device, and avoid the problem of uneven heat dissipation in the prior art. The heat on the cooling fins passes through the heat sink to the fin group, and the cold drive device cools down the fin group, so as to accelerate heat dissipation in a composite heat exchange mode with an increased area, so that the cold compress device can achieve a freezing point effect when in contact with the skin.

[0012] Furthermore, the fins on the first fin group and the second fin group are arranged perpendicular to the radial direction of the hair removal device body, and the first fin group and the second fin group are arranged in parallel or cross each other.

[0013] Furthermore, the cooling drive device is a fan, and the air outlet of the fan is directed toward the first fin group and the second fin group.

[0014] Furthermore, the first and second heat dissipation components are fixed to a bracket, and the bracket is provided with a diverter plate at the air outlet. The diverter plate divides the bracket into a first air duct passing through the first and second fin groups, and a second air duct passing through the hair removal device. One end of each of the first and second air ducts is connected to the air outlet, and the other ends of each of the first and second air ducts are connected to a heat dissipation port on one side of the hair removal device body. The division of the air duct into the first and second air ducts by the diverter plate avoids airflow interference and facilitates cooling.

[0015] Furthermore, the bracket includes a first frame and a second frame. The upper end surface of the first frame and the lower end surface of the second frame are both provided with a relief groove for mounting the fin group. The relief groove is connected to the first air duct. The first and second fin groups pass through the corresponding relief grooves and are positioned within the first air duct. The provision of the relief grooves can further simplify the installation of the heat dissipation assembly.

[0016] Furthermore, the first heat sink and the second heat sink are connected to the bracket by fasteners, and the first heat sink and the second heat sink can cover and seal the avoidance groove. The heat sink covering and sealing the avoidance groove can ensure smooth air flow and better achieve heat dissipation of the fin group.

[0017] Furthermore, the shell of the hair removal device body is provided with an air inlet hole at a position corresponding to the fan, so as to facilitate the entry of external cold air into the fan.

[0018] Furthermore, the hair removal device body is also provided with a processor, a contact sensing module and a skin color sensing module. The contact sensing module is used to sense whether the hair removal device is in contact with the skin, and the skin color sensing module is used to detect the skin color and adjust the energy output by the hair removal device. The contact sensing module and the skin color sensing module are both arranged at the working end of the hair removal device body, and the output ends of the contact sensing module and the skin color sensing module are both electrically connected to the receiving end of the processor, and the output end of the processor is electrically connected to the receiving end of the hair removal device.

[0019] Furthermore, the hair removal device includes a lamp tube, a reflective cup and a filter. The filter is attached to the side wall surface of the cold compress device. The reflective cup and the filter together form an installation space for the lamp tube.

[0020] Furthermore, the cold compress device is made of crystalline or amorphous materials with high light transmittance and good heat dissipation, such as inorganic borosilicate glass, graphene glass, sapphire, or silicate glass. The cold compress device is preferably made of sapphire, which is preferred primarily to cool the light outlet, reduce burning pain, and avoid skin damage.

[0021] Furthermore, multiple cold compress blocks are arranged in a straight line to form a cold compress. A second heat-conducting layer is provided on the side surface of the cold compress, and this second heat-conducting layer is connected to the first heat-conducting layer. The first and second cooling fins are also connected to the second heat-conducting layer. The second heat-conducting layer further conducts heat from the first heat-conducting layer. This dual heat-conducting layer allows for simultaneous heat dissipation inside and outside the cold compress, resulting in a more significant cooling effect.

[0022] In addition, two adjacent cold compress blocks are connected by a connecting layer, and the connecting layer is an adhesive glue, and the adhesive glue is preferably a high-temperature resistant and high-thermal conductive adhesive glue.

[0023] The present invention has the following advantages: the present invention conducts heat from the inside of the cold compress through the first heat-conducting layer, and cooperates with the second heat-conducting layer to conduct heat from the outside of the cold compress to the refrigeration device of the hair removal device, thereby achieving simultaneous heat conduction inside and outside the cold compress device. At the same time, dual passive heat dissipation components act on the cold compress device, ensuring that the cold compress device can dissipate heat evenly, and multiple fin groups are provided to increase the large area of ​​heat exchange to improve heat dissipation efficiency and avoid burning pain during use.

[0036] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below with reference to the accompanying drawings.

[0038] like Figures 4 to 7 As shown, the cold compress device 2 of this embodiment includes a plurality of cold compress blocks 21, each of which includes a substrate 22 and a first heat-conducting layer 24 coated on the side surface of the substrate 22. The upper and lower end surfaces of the substrate 22 (such as Figure 4 The upper and lower position relationships shown in the figure are both transparent surfaces 23. In this embodiment, the transparent surfaces 23 can be designed to be parallel to each other, and the planes where the first heat conducting layer 24 is located are perpendicular to the transparent surfaces 23, making it easier for the light beam to be emitted. Figure 5 and Figure 6 As shown, multiple cold compress blocks 21 are arranged in a straight line. In order to ensure better contact with the skin, in this embodiment, the light-transmitting surfaces 23 of two adjacent cold compress blocks 21 are set flush, and the side surfaces of the two adjacent cold compress blocks 21 are connected by a connecting layer 27 to form a cold compress 25. The connecting layer 27 is an adhesive. Preferably, the connecting layer 27 is a high-temperature resistant and highly thermally conductive adhesive. In this embodiment, the plane where the connecting layer 27 is located can be perpendicular to the light-transmitting surface 23. Figure 6 and Figure 7 The side surface of the cold compress 25 is coated with a second heat-conducting layer 26, which is connected to the first heat-conducting layer 24, so that the first heat-conducting layer 24 can transfer the heat inside the cold compress structure to the second heat-conducting layer 26. In this embodiment, the plane where the second heat-conducting layer 26 is located is perpendicular to the light-transmitting surface 23.

[0039] Specifically, if Figure 4 As shown, the substrate 22 is made of light-transmitting crystals or amorphous materials, and the crystals or amorphous materials include but are not limited to quartz glass, sapphire, special glass and other materials. The thickness of the first heat-conducting layer 24 is 0.05mm-0.3mm. Preferably, the thickness of the first heat-conducting layer 24 is 0.1mm. The first heat-conducting layer 24 includes common metals, alloys and non-metallic materials, such as ceramics, graphene, silicon, silver, copper, aluminum, gold and other materials. Preferably, the first heat-conducting layer 24 is a conductive paste, and further preferably, the conductive paste is a silver paste. Figure 7 As shown, the thickness of the second heat-conducting layer 26 is 0.05 mm to 0.3 mm. Preferably, the thickness of the second heat-conducting layer 26 is 0.1 mm. The second heat-conducting layer includes common metals, alloys, and non-metallic materials, such as ceramics, graphene, silicon, silver, copper, aluminum, gold, etc. Preferably, the second heat-conducting layer 26 is a graphene film layer.

[0040] The manufacturing method of the cold compress device 2 of this embodiment includes the following steps:

[0041] Step 1: Prepare substrate 22: Figure 4 As shown, the substrate 22 is processed into a block shape according to size requirements.

[0042] Step 2: Coating the first heat-conducting layer 24: Figure 4 As shown, a first heat-conducting layer 24 is coated on the side surface of a substrate 22 to form a cold compress block 21 .

[0043] Step 3: Connect the cold compress 21: Figure 5 and Figure 6As shown, a plurality of the cold compress blocks 21 are arranged in a straight line and connected to each other to form a cold compress 25 , and the adjacent light-transmitting surfaces 23 on at least one side of the cold compress block 21 are flush, and the plurality of the cold compress blocks 21 are connected by a connecting layer 27 .

[0044] Step 4: Apply the second heat-conducting layer 26: Figure 7 As shown, a second heat-conducting layer 26 is coated on the side surface of the cold compress 25 , and the second heat-conducting layer 26 is connected to the first heat-conducting layer 24 .

[0045] like Figure 7 As shown, in this embodiment, multiple cold compress blocks 21 are provided so that the heat on each cold compress block 21 is taken away by the first heat-conducting layer 24 provided on its side surface, thereby achieving uniform cooling of the entire cold compress device 2. At the same time, multiple cold compress blocks 21 are combined into a cold compress member 25, and the double heat-conducting layer 26 is used to achieve simultaneous heat dissipation inside and outside the cold compress member 25. Figure 7 and Figure 9 As shown, when used in conjunction with the heat dissipation device 3, the cold compress device 2 can be effectively cooled as a whole, achieving a good cold compress effect on the skin near the light outlet, alleviating the burning sensation of the skin, and avoiding damage to the user's skin caused by cooling dead corners.

[0046] like Figure 8 and Figure 9 As shown, the heat dissipation device 3 includes a first heat dissipation component 31 and a second heat dissipation component 32. The first heat dissipation component 31 includes a first cooling fin 311, a first heat sink 312 and a first fin group 313, and the first cooling fin 311 and the first fin group 313 are installed at intervals on the lower end surface of the first heat sink 312. The second heat dissipation component 32 includes a second cooling fin 321, a second heat sink 322 and a second fin group 323, and the second cooling fin 321 and the second fin group 323 are installed at intervals on the upper end surface of the second heat sink 322. Specifically, the fins on the first fin group 313 and the second fin group 323 are arranged perpendicular to the radial direction of the hair removal device body 1, and the first fin group 313 and the second fin group 323 are arranged in parallel or crosswise with each other.

[0047] like Figure 2 and Figure 9 As shown, specifically, the first cooling plate 311 is attached to the upper end surface of the cold compress device 2, and the second cooling plate 321 is attached to the lower end surface of the cold compress device 2 (as shown in FIG. Figure 9The upper and lower positional relationship shown in the figure). The cold compress device 2, the first heat dissipation component 31 and the second heat dissipation component 32 together form an installation space for the hair removal device 4. The hair removal device 4 includes a lamp 41, a reflective cup 42 and a filter 43. The filter 43 is attached to the side wall of the cold compress device 2. The reflective cup 42 and the filter 43 together form an installation space for the lamp 41. The filter 43 can filter unnecessary harmful light and invalid light to achieve a good hair removal effect. When in use, the light emitted by the lamp 41 is emitted through the filter 43 and the cold compress device 2. The cold drive device 5 is used to cool the first fin group 313 and the second fin group 323. The cold drive device 5 is preferably a fan, and the air outlet 51 of the fan is oriented towards the first fin group 313 and the second fin group 323. At the same time, the shell of the hair removal device body 1 is provided with an air inlet 14 at the corresponding position of the fan to facilitate the entry of external cold air into the fan. In other embodiments, the cold compress device 2 may also be made of crystalline or amorphous materials with high light transmittance and good heat dissipation, such as inorganic borosilicate glass, graphene glass, and silicate glass.

[0048] like Figure 9 As shown, the first and second heat sinks 312 and 322 are preferably VC heat sinks. Made of pure copper, they are sealed and hollow, with a rough, capillary structure. A capillary copper mesh accelerates backflow and is filled with condensate, creating a heat dissipation unit that involves four steps: conduction, evaporation, convection, and solidification. During operation, the first and second cooling fins 311 and 321 transfer heat from the cold compress device 2 to the evaporation end of the VC heat sink. The condensate within quickly absorbs this heat and converts it into vapor, removing a significant amount of heat energy. Due to the latent heat of water vapor, the hot vapor from the VC heat sink diffuses from the high-pressure area to the low-pressure area (the condensation end). When the vapor contacts the cooler inner wall, it quickly condenses into liquid, releasing heat energy. Finally, the liquid flows back to the evaporation end through capillary action, ultimately forming a two-phase circulation system where water and vapor coexist. Because the VC heat sinks are in direct contact with the heat source without the need for a substrate, thermal resistance can be further reduced.

[0049] like Figures 9 to 11As shown, the first heat dissipation assembly 31 and the second heat dissipation assembly 32 are fixed to the bracket 13. The bracket 13 includes a first frame 134 and a second frame 135. The upper end surface of the first frame 134 and the lower end surface of the second frame 135 are both provided with a avoidance groove 136 for installing the fin group. The bracket 13 is provided with a diverter plate 133 at the air outlet 51. The diverter plate 133 divides the bracket 13 into a first air duct 131 passing through the first fin group 313 and the second fin group 323, and a second air duct 132 passing through the hair removal device 4, avoiding airflow interference between the two air ducts and facilitating cooling. One end of each of the first air duct 131 and the second air duct 132 is connected to the air outlet 51, and the other end of each of the first air duct 131 and the second air duct 132 is connected to the heat dissipation port 12 on one side of the hair removal device body. The use of two independent air ducts can avoid airflow interference and facilitate cooling. The avoidance groove 136 is connected to the first air duct 131, and the first fin group 313 and the second fin group 323 pass through the corresponding avoidance groove 136 and are placed in the first air duct 131. The first heat sink 312 and the second heat sink 322 are connected to the bracket 13 by fasteners, and the first heat sink 312 and the second heat sink 322 can cover and seal the avoidance groove 136. It is convenient for processing and installation of the heat dissipation component, and is conducive to heat dissipation. By acting on the cold compress device with dual passive heat dissipation components, it is ensured that the cold compress device can dissipate heat evenly, and multiple fin groups are set to increase the large area of ​​heat exchange to improve the heat dissipation efficiency and avoid burning pain during use.

[0050] When this embodiment is in use, the fan draws in cool air from the outside through the air inlet and blows it out through the air outlet. The cool air at the air outlet is split into two streams by the diverter plate and enters the first air duct and the second air duct respectively. The cool air in the first air duct removes heat from the fin assembly, while the cool air in the second air duct removes heat from the hair removal device. The first and second air ducts finally converge at the heat dissipation outlet and are discharged to the outside.

[0051] It will be understood that the present invention is described by way of some embodiments, and it will be appreciated by those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
