Description

[Technical field]

[0001] The invention relates to the technical field of hair removal devices, and in particular to a hair removal device. [Background technology]

[0002] In order to remove body hair, people use various methods for hair removal. Generally, the most common method is light hair removal, which is to irradiate the skin with intense pulsed light. The pigment in the hair follicles of the skin absorbs the light energy and generates heat, causing the hair follicles to necrotize and cause the hair to fall off. The hair will no longer grow, thus achieving the purpose of long-term hair removal.

[0003] Generally, hair removal devices use an intense pulse light source as the hair removal light source. The intense pulse light source is a lamp tube sealed with an inert gas (such as xenon), and a coil is wound around the lamp tube. When working, the capacitor is first charged, then discharged, and voltage is applied to the positive and negative poles of the lamp tube. Then, voltage is applied to the coil to ionize the inert gas in the lamp tube and conduct electricity. Finally, the positive and negative poles of the lamp tube are turned on and the lamp tube emits light. When the lamp tube is turned on and emits light, the electrodes of the lamp tube will also emit a large amount of heat, causing the temperature of the contact part at the light outlet of the hair removal device to rise sharply. When the contact part touches the skin, the skin becomes hot, and the hair removal experience is poor.

[0004] In order to solve the above problem, the existing hair removal device generally sets a heat dissipation component in the shell, and removes the heat of the contact part through the heat dissipation component to reduce its temperature. However, setting the heat dissipation component in the shell makes the shell crowded, the heat dissipation space is small, the heat dissipation effect is poor, the temperature reduction of the contact part is limited, and the effect is not ideal.

[0040] The hair removal device 100 of the present application includes a hair removal mechanism 20 and a cold compress mechanism 10. The hair removal mechanism 20 and the cold compress mechanism 10 exist as two independent modules and are electrically connected to each other. The hair removal mechanism 20 and the cold compress mechanism 10 can be detachably electrically connected or fixedly connected. The hair removal mechanism 20 is used to irradiate the skin with intense pulsed light. The pigment in the hair follicles of the skin absorbs light energy to generate heat, causing the hair follicles to necrotize and cause the hair to fall off. The hair will no longer grow, thereby achieving the purpose of long-term hair removal. The cold compress mechanism 10 covers the light outlet hole 218 of the hair removal mechanism 20. The hair removal mechanism 20 is indirectly in contact with the skin through the cold compress mechanism 10. The cold compress mechanism 10 has a cooling effect, thereby avoiding the burning sensation caused by the hair removal mechanism 20 to the skin.

[0041] In order to enable those skilled in the art to have a further understanding of the present application, the cold compress mechanism 10 will be described in detail below.

[0042] The cold compress mechanism 10 includes a cold compress shell assembly 11 , a cold compress module 12 and a heat pipe 13 .

[0043] The cold compress shell assembly 11 is provided with a cold compress hole 117, a first heat dissipation hole 115, and a second heat dissipation hole 118, and the hair removal mechanism 20 is provided with a first air outlet 212, a second air outlet 214, and a heat dissipation channel 216. The cold compress shell assembly 11 is connected to the hair removal mechanism 20. After the cold compress shell assembly 11 and the hair removal mechanism 20 are assembled, the cold compress shell assembly 11 and the hair removal mechanism 20 are separated by a first air flow channel 116 at the cold compress module 12, and a second air flow channel 119 is formed inside the cold compress shell assembly 11. The first air outlet 212, the first heat dissipation hole 115, the first air flow channel 116, and the second heat dissipation hole 118 are connected in sequence, the first air outlet 212, the first heat dissipation hole 115, the second air flow channel 119, and the second heat dissipation hole 118 are connected in sequence, and the second air outlet 214 is connected to the second heat dissipation hole 118. The first air flow channel 116, the second air flow channel 119, and the heat dissipation channel 216 are arranged at intervals.

[0044] The cold compress module 12 is assembled in the cold compress hole 117 and connected to the cold compress shell assembly 11, and the light emitted by the hair removal mechanism 20 is emitted from the cold compress module 12. The cold compress module 12 is used to contact the skin, and the cold compress module 12 has a refrigeration effect, thereby achieving a cooling effect.

[0045] The heat pipe 13 is accommodated in the cold compress shell assembly 11, one end of the heat pipe 13 is connected to the cold compress module 12, and the other end extends to the second air flow channel 119 between the first heat dissipation hole 115 and the second heat dissipation hole 118. The heat pipe 13 transfers the heat of the cold compress module 12 to the first heat dissipation hole 115 and the second heat dissipation hole 118 and discharges it through the second heat dissipation hole 118. The heat pipe 13 makes full use of the heat conduction principle and the rapid heat transfer property of the phase change medium, and quickly transfers the heat in the cold compress module 12 to the far end of the heat source through the heat pipe 13. Its thermal conductivity exceeds the thermal conductivity of any known metal. Further, the cold compress mechanism 10 also includes a plurality of fins 16, and the plurality of fins 16 are sleeved on the heat pipe 13 corresponding to the second heat dissipation hole 118 to increase the contact area between the heat pipe 13 and the air and improve the heat dissipation efficiency. The fins 16 are U-shaped, and the plurality of fins 16 are sleeved on the heat pipe 13 and abut against each other to form a support for each other.

[0046] Part of the heat in the hair removal mechanism 20 is discharged through the second air outlet 214 and the second heat dissipation hole 118 in sequence; another part of the heat in the hair removal mechanism 20 is discharged through the first air outlet 212, the first air flow channel 116, and the second heat dissipation hole 118 in sequence, and the water vapor in the cold compress shell assembly 11 is taken out; another part of the heat in the hair removal mechanism 20 is discharged through the first air outlet 212, the second air flow channel 119, and the second heat dissipation hole 118 in sequence, and the heat near the heat pipe 13 is taken out.

[0047] The cold compress shell assembly 11 includes a first cold compress inner shell 112, a second cold compress outer shell 114 and an end cover 113. The second cold compress outer shell 114 and the first cold compress inner shell 112 are plugged into each other, and the end cover 113 is connected to the second cold compress outer shell 114 and abuts against the first cold compress inner shell 112, thereby completing the fixation of the three. The hair removal mechanism 20 is inserted into the first cold compress inner shell 112 to achieve the purpose of detachability, which can be an interference fit. Of course, the hair removal mechanism 20 and the cold compress mechanism 10 can also achieve the purpose of detachability through magnetic attraction.

[0048] The first heat dissipation hole 115 is opened on the first cold compress inner shell 112, the second heat dissipation hole 118 is opened on the end cover 113, the cold compress hole 117 passes through the first cold compress inner shell 112 and the second cold compress outer shell 114, and a second air flow channel 119 is formed between the first cold compress inner shell 112 and the second cold compress outer shell 114.

[0049] The first cold compress inner shell 112 may be made of a heat-insulating material such as nylon to prevent the heat in the hair removal mechanism 20 from being transferred to the cold compress mechanism 10 through the first cold compress inner shell 112 , thereby reducing the cooling effect of the cold compress module 12 .

[0050] In this embodiment, the cold compress module 12 includes sapphire 121, a conductive member 122 and a cooling plate 123, wherein the conductive member 122 is used to install the sapphire 121 in the cold compress hole 117 surrounded by the first cold compress shell 112 and the second cold compress shell 114, and is used to contact the cooling plate 123 to conduct heat from the sapphire 121 and itself, ultimately maintaining the sapphire 121 and the conductive member 122 at a low temperature.

[0051] Specifically, the conductive member 122 includes a sleeve portion 1221, a cold compress portion 1222 disposed at one end of the sleeve portion 1221, a sleeve hole 1223 formed by the sleeve portion 1221, and a fixing column 1224 disposed on the cold compress portion 1222. The cold compress portion 1222 partially extends to the sleeve hole 1223 to form a pressing portion 1225. The sapphire 121 is received in the sleeve hole 1223, with one side of the sapphire 121 abutting against the second cold compress shell 114, and the other side abutting against the pressing portion 1225 of the cold compress portion 1222. The first cold compress shell 112 is provided with a through hole 1121, and the fixing column 1224 of the conductive member 122 passes through the through hole 1121 and is fixed to the second cold compress shell 114 by screws. The cold compress portion 1222 abuts against the first cold compress shell 112, and the pressing portion 1225 presses the sapphire 121 onto the second cold compress shell 114, so that the sapphire 121 is clamped and fixed between the cold compress portion 1222 and the second cold compress shell 114, thereby completing the fixation of the sapphire 121.

[0052] In order to increase the stability of the fixation of the sapphire 121, steps are provided at both ends of the sapphire 121 where the pressing portion 1225 and the second cold compress shell 144 abut against each other. The pressing portion 1225 and the second cold compress shell 144 are respectively clamped with the steps at both ends of the sapphire 121 and squeezed against each other.

[0053] The cooling sheet 123 is attached to the side of the sleeve portion 1221 away from the sapphire 121, and absorbs the heat of the sapphire 121 and the cold compress portion 1222 through the sleeve portion 1221, so that the sapphire 121 and the cold compress portion 1222 maintain low temperatures. When the cold compress portion 1222 and the sapphire 121 are in contact with human skin, the human skin is cooled to reduce the temperature of the human skin. The conductive member 122 can be made of a metal material with high thermal conductivity, such as aluminum and copper.

[0054] In other embodiments, the cold compress module 12 includes or may only include sapphire 121 and cooling plate 123. The sapphire 121 is received in the cold compress hole 117 and is clamped and fixed by the first cold compress shell 112 and the second cold compress shell 114, while the cooling plate 123 is directly attached to the side of the sapphire 121, so that the sapphire 121 can be cooled more quickly and maintain a lower temperature, thereby having a better cold compress effect.

[0055] The sapphire 121 is not only light-transmissive, but also has excellent thermal conductivity, which can ensure efficient thermal conductivity between the cooling plate 123 and the sapphire 121, so that the sapphire 121 has a stable low temperature. Of course, the sapphire 121 can also be replaced by ordinary glass or other light-transmissive objects.

[0056] For further information, see Figure 7 , two cooling sheets 123 are attached to both sides of the sleeve 1221, one side of the heat pipe 13 is fixed on the fixing seat 18, and the other side of the heat pipe 13 is attached to the side of the cooling sheet 123 away from the sleeve 1221. The cooling sheet 123 is a semiconductor cooling sheet, and its cooling surface is in contact with the sleeve 1221 to absorb the heat of the sleeve 1221 and the sapphire 121, thereby reducing the temperature of the sleeve 1221 and the sapphire 121; and the heat dissipation surface of the cooling sheet 124 is in contact with the heat pipe 13, and the heat of the heat dissipation surface of the cooling sheet 124 is absorbed by the phase change of the medium in the heat pipe 13, thereby ensuring the normal operation of the cooling sheet 124.

[0057] In other embodiments, the sleeve portion 141 may be provided with a cutout, and the sapphire 121 is installed in the cutout and in direct contact with the cooling plate 123 .

[0058] The cold compress mechanism 10 also includes a fixed shell 15, which includes a fixed wall 151, a plug-in portion 152 arranged on one end of the fixed wall 151, and a fixed frame 153 arranged in the fixed wall 151. The second cold compress outer shell 114 is provided with a slot 1141, and the fixed shell 15 is fixed to the first cold compress inner shell 112 by plugging the plug-in portion 152 into the slot 1141.

[0059] The hair removal device 100 may damage the hair follicles during hair removal. If not treated, the hair follicles may become inflamed, which may affect the health of the user. In order to solve the above problems, the hair removal device 100 is also provided with a plurality of sterilization and disinfection modules 30, which are fixed on the first cold compress inner shell 112. Each sterilization and disinfection module 30 includes a light board 32 and a sterilization lamp 34 provided on the light board 32. The light board 32 is fixed to the first cold compress inner shell 112, and the sterilization lamp 34 faces the edge of one end of the sapphire 121. Optionally, the sterilization lamp 34 is an LED lamp that can emit blue light.

[0060] After the user uses the hair removal device 100 to remove hair, the sterilization module 30 is turned on, and the light emitted by the sterilization lamp 34 is transmitted through the sapphire 121 to irradiate the human skin, sterilizing and disinfecting the hair follicles of the skin, thereby preventing inflammation of the user's skin follicles.

[0061] In order to enable those skilled in the art to have a further understanding of the present application, the hair removal mechanism 20 will be described in detail below.

[0062] The hair removal mechanism 20 includes a hair removal housing component 21 , a filter 22 , a light emitting component 23 and a fan 24 .

[0063] The depilatory shell assembly 21 includes a middle shell 211 which is cylindrical and has openings at both ends, a lower shell 213 and an upper shell 215 connected to both ends of the middle shell 211. The inner wall of the middle shell 211 is formed with an air inlet channel 2111 and is provided with a plurality of slide grooves 2112 for fixing the fan 24. The lower shell 213 is provided with a plurality of air inlet holes 2131 connected with the air inlet channel 2111. The upper shell 215 is provided with a light outlet hole 218 and a first air outlet hole 212 and a second air outlet hole 214. The light outlet hole 218 is opposite to the cold compress hole 117. The depilatory shell assembly 21 and the cold compress shell assembly 11 form a first air flow channel 116 between the light outlet hole 218 and the cold compress hole 117. The depilatory shell assembly 21 is formed with a heat dissipation channel 216 which is spaced from the first air flow channel 116 and the second air flow channel 119 respectively. The heat dissipation channel 216 is connected with the air inlet channel 2111. The cold compress shell component 11 and the depilatory shell component 21 can be detachably connected, and the two can be detachably connected by interference fit. The depilatory shell component 21 can be straight-cylindrical to shorten the length of the heat dissipation channel 216, reduce the path of air circulation to the second heat dissipation hole 118, and allow heat to be quickly discharged with the air. Optionally, the light-emitting component 23 is an intense pulse light source.

[0064] The filter 22 is assembled in the light outlet 218 and connected to the hair removal shell assembly 21. Since the light emitting assembly 23 is an intense pulse light source, the light it emits includes ultraviolet rays and visible light. Ultraviolet rays can easily cause damage to human skin. Therefore, the filter 22 is needed to filter the ultraviolet rays generated by the light emitting assembly 23. In addition, the light emitting assembly 23 generates a large amount of heat during hair removal, and the filter 22 rapidly heats up due to absorbing the heat generated by the light emitting assembly 23. By spacing the filter 22 and the cold compress module 12 to form a first airflow channel 116, the heat insulation capacity of the filter 22 and the cold compress module 12 is greatly improved, and heat is prevented from being transferred from the high-temperature filter 22 to the cold compress module 12, so that the cold compress module 12 maintains a low temperature. When the cold compress module 12 contacts the human skin, the low-temperature cold compress module 12 effectively lowers the temperature of the skin, while passivating the skin sensitivity, thereby improving the user experience. In addition, a first air flow channel 116 is formed between the optical filter 22 and the cold compress module 12. The air in the first air flow channel 116 will take away the water vapor during the flow of air, thereby preventing the optical filter 22 from bursting when encountering the water vapor.

[0065] The light emitting component 23 is assembled in the hair removal shell component 21 , and the light emitted by the light emitting component 23 is emitted from the filter 22 and the cold compress module 12 in sequence.

[0066] The fan 24 is installed in the depilatory shell assembly 21, and is used to blow air toward the first air outlet 212 and the second air outlet 214. The fan 24 is used to accelerate the flow of air and make the air move in a certain direction. Figure 3 In the direction indicated by the arrow, under the action of the fan 24, part of the heat in the hair removal mechanism 20 is discharged through the second air outlet 214 and the second heat dissipation hole 118 in sequence; another part of the heat in the hair removal mechanism 20 is discharged through the first air outlet 212, the first air flow channel 116, and the second heat dissipation hole 118 in sequence, and the water vapor in the cold compress shell assembly 11 is taken out; another part of the heat in the hair removal mechanism 20 is discharged through the first air outlet 212, the second air flow channel 119, and the second heat dissipation hole 118 in sequence, and the heat near the heat pipe 13 is taken out. The fan 24 can be an axial flow fan, and the fan 24 can also be a blower.

[0067] The light emitting assembly 23 includes a lamp tube 232 and a reflector 234 which are assembled in the depilatory shell assembly 21. The reflector 234 covers the lamp tube 232. The length direction of the lamp tube 232 is consistent with the air outlet direction of the fan 24. Alternatively, it can be understood that the connecting direction of the second air outlet 214 and the second heat dissipation hole 118 is consistent with the length direction of the lamp tube 232. The lamp tube 232 is placed along the direction of air flow in the depilatory shell assembly 21 to reduce the obstruction of the lamp tube 232 to the air flow and increase the air flow rate in the depilatory shell assembly 21.

Optionally, the interface 26 is a MicroUSB interface, a USB Type-C interface or a contact, and the plug 17 is a MicroUSB plug, a USB Type-C plug or a probe adapted to the interface 26.

It is worth noting that the plug 17 and the interface 26 are arranged for electrical conduction, and when the electrical conduction is realized by replacing the pin and the socket, it is also within the scope of protection of this application.

The main body 253 is provided on opposite sides of the fixing portion 251. The heat dissipation portion 255 is connected to the main body 253. The heat dissipation portion 255 is used to increase the contact area with the air.

The fixed shell 248 is directly connected to the middle shell 211 of the depilatory shell assembly 21. The connection method can be a sliding fit and mutual interference fit. At this time, the slide groove 2112 and the protrusion 249 are respectively arranged on the middle shell 211 and the fixed shell 248, so that the two can be fixed without a locking structure, reducing the fixed parts of the fan 24, reducing the internal space occupied by the fan 24 in the depilatory mechanism 20, and facilitating the miniaturization of the depilatory mechanism 20 and convenient holding.

[0077] In another embodiment, if Fig.11 and Fig.12 As shown, the fan 24 includes: a stator 242, a rotor 244 and a bracket 246, the rotor 244 is rotatably connected to the stator 242, the bracket 246 is connected to the stator 242, and the bracket 246 is directly slidably matched with the depilatory shell assembly 21, and the slide groove 2112 and the protrusion 249 are respectively arranged on the middle shell 211 and the bracket 246.

[0081] Fig.13 and 14 This is a second embodiment of the hair removal device 100 ′, wherein the difference between the second embodiment and the first embodiment lies in the arrangement of the air flow channel and the fixing method of the fan 24 ′, so only the above differences are described.

[0082] In this embodiment, the hair removal device 100' includes a detachably connected hair removal mechanism 20' and a cold compress mechanism 10', and the cold compress mechanism 10' includes: a cold compress shell assembly 11', a cold compress module 12', a heat pipe 13' connected to the cold compress module 12', and a plurality of heat sinks 16' fixed on the end of the heat pipe 13' away from the cold compress mechanism 10'. The cold compress shell assembly 11' is provided with a cold compress hole 117', a first heat dissipation hole 115' and a second heat dissipation hole 118' and a heat dissipation space 18', and the heat dissipation space 18' is provided with a third air inlet 181'.

[0083] The cold compress shell assembly 11' is detachably connected to the hair removal mechanism 20'. After the cold compress shell assembly 11' and the hair removal mechanism 20' are assembled, a first air flow channel 116' is formed between the cold compress shell assembly 11' and the hair removal mechanism 20'. The two ends of the first air flow channel 116' are respectively connected to the first air outlet 212' and the third air outlet 181'.

[0084] The depilatory mechanism 20' comprises a depilatory shell assembly 21', a filter 22', a light emitting assembly 23', a fan 24' and a lamp holder 25', wherein the light emitting assembly 23' is fixed in the depilatory shell assembly 21' through the lamp holder 25'. The depilatory shell assembly 21' is provided with a light outlet 218', a first air outlet 212' and a second air outlet 214', wherein the light outlet 218' is opposite to the cold compress hole 117', and the depilatory shell assembly 21' is formed with a heat dissipation channel 216', wherein the second air outlet 214' is connected to the first heat dissipation hole 115'. Specifically, the filter 22' is assembled in the light outlet 218' and connected to the depilatory shell assembly 21', and a first air flow channel 116' isolated from the heat dissipation channel 216' is formed between the filter 22' and the cold compress module 12'.

[0085] The fan 24' is installed in the depilatory shell assembly 21', and the fan 24' is used to blow air toward the first air outlet 212' and the second air outlet 214'. The fan 24' is used to accelerate the flow of air and make the air move in a certain direction. Fig.14 In the direction indicated by the arrow, under the action of the fan 24', a part of the heat in the depilatory shell component 21' passes through the heat dissipation channel 216', the second air outlet 214', the first heat dissipation hole 11', the heat dissipation space 18' and the second heat dissipation hole 118' in sequence and is discharged from the depilatory device 100'. Another part of the heat in the depilatory shell component 21' passes through the first air outlet 212', the first air flow channel 116', the third air outlet 181', the heat dissipation space 18' and the second heat dissipation hole 118' in sequence and is discharged from the depilatory device 100', and the water vapor in the cold compress shell component 11' is taken out at the same time. The first air flow channel 116' and the heat dissipation channel 216' are independent of each other and do not affect each other.

[0086] The fan 24' includes a stator 242' and a rotor 244' that are rotatably matched, and a retaining wall 243' that surrounds the stator 242' and the rotor 244'. The retaining wall 243' has an air outlet 2431' that is connected to the first airflow channel 116' and the heat dissipation channel 118'. The stator 242' and the retaining wall 243' are directly fixed on the depilatory shell assembly 21', and the depilatory shell assembly 21' is provided with an air inlet 219'. When the rotor 244' is working, the stator 244' pushes the air flow in the retaining wall 243', and generates an airflow at the air outlet 2431' that blows toward the first airflow channel 116' and the heat dissipation channel 216', thereby carrying the heat in the first airflow channel 116' and the heat dissipation channel 216', so as to reduce the temperature of the filter 22' and the cold compress module 12', and the light emitting assembly 23' and the lamp holder 25' respectively. Since the stator 242' and the retaining wall 243' are directly fixed to the depilatory housing assembly 21', the housing for fixing the fan 24' is omitted, the volume of the fan 24' is reduced, and the volume of the depilatory device 100' can be further reduced, so that it is convenient for users (especially female users) to hold.

[0088] The above description is only an implementation mode of the present invention. It should be pointed out that, for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present invention, but these all belong to the protection scope of the present invention.
