Description

Technical Field

[0001] This utility model belongs to the field of beauty device technology, and in particular relates to an intense pulsed light therapy device. Background Technology

[0002] Intense pulsed light (IPL) therapy devices, commonly known as hair removal devices, use the principle of laser hair removal to remove hair from the epidermis. Laser hair removal utilizes the "selective photothermal effect" of lasers, using a specific wavelength of laser light to penetrate the epidermis and directly target the hair follicle. The melanin in the target tissue, such as the hair follicle and hair shaft, selectively absorbs the light energy, and the resulting thermal effect causes coagulative necrosis or denaturation of the hair follicle, preventing hair regrowth. During use, because the photon energy of the intense pulse is converted into heat energy, the device generates a significant amount of heat. Therefore, improving the heat dissipation of the hair removal device is crucial.

[0003] In the prior art, the hair removal device disclosed in Chinese Patent Publication No. CN218552432U includes a housing and an optical hair removal mechanism, a thermally conductive insulating component, and a heat dissipation structure installed within the housing. The optical hair removal mechanism emits light outwards. The thermally conductive insulating component is sandwiched between the optical hair removal mechanism and the heat dissipation structure, and is respectively attached to the optical hair removal mechanism and the heat dissipation structure. The hair removal device also includes an air guide component. The side of the second bracket has an air guide plate with openings. The air guide plate, together with the air guide component and the housing, can form an air duct. The air outlet of the fan includes a first air outlet, which corresponds to one end of the air duct. The design involves drawing air from a fan into an air duct. The air first flows to one end of the lamp tube and then through a ventilation cavity to the other end. Since the two ends of the lamp tube are not simultaneously exposed to air, one end of the lamp tube will be hotter than the other. The airflow path is longer during heat dissipation, resulting in low heat dissipation efficiency and poor heat dissipation, which affects the user experience of the hair removal device. Moreover, after long-term use, the lamp tube may develop quality problems due to uneven heating on different parts of its surface, leading to a reduction in lamp tube lifespan. Furthermore, in this design, the air outlet and air inlet on the upper surface of the outer shell are close to each other, causing interference between the incoming and outgoing air. This results in multiple airflows circulating inside the device, affecting the direction of airflow and thus impacting the overall heat dissipation effect.

[0004] Therefore, it is necessary to provide intense pulsed light therapy devices to solve the above-mentioned technical problems. Utility Model Content

[0005] The main purpose of this invention is to provide a strong pulsed light therapy device that can not only solve the problem of heat dissipation affected by wind direction fluctuations, but also improve the heat dissipation effect and solve the problem of lamp tube life reduction caused by uneven heating at different parts of the lamp tube surface.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: an intense pulsed light therapy device, comprising a housing and a control circuit board, a light-emitting component, a hair removal component, a cooling component, a heat-conducting component, and a heat dissipation component disposed inside the housing. One end of the housing has a light outlet, and the housing has a first air outlet on its upper surface near the light outlet and a first air inlet / outlet on its upper surface away from the light outlet. The heat-conducting component has end A sandwiched between the light outlet and the light-emitting component, and end B sandwiched between the light-emitting component and the heat dissipation component. Between them, the cooling component is disposed at the light outlet and in contact with end A of the heat-conducting component. At the same time, the heat-conducting component transfers heat from end A to end B. A partition mounting base is provided between the heat dissipation component and the light-emitting component to form two airflow channels. End B of the heat-conducting component and the partition mounting base together form a first airflow channel to dissipate heat from end B of the heat-conducting component. End B of the light-emitting component and the partition mounting base together form a second airflow channel to dissipate heat from the light-emitting component.

[0007] Furthermore, the hair removal component is disposed at the light outlet, and the hair removal component includes a first mounting base, a filter disposed on one side of the first mounting base, a contact disposed on the other side of the first mounting base, and a trigger coil mounted on the contact. A sealing element is provided around the filter.

[0008] Furthermore, the first mounting base has a first mounting cavity for mounting the filter on one side and a second mounting cavity for mounting the contact and communicating with the first mounting cavity on the other side. A first limiting hook is provided on the outer side of the first mounting cavity to restrict the filter from slipping out, and a first limiting protrusion is provided in the second mounting cavity to restrict the movement of the contact.

[0009] Furthermore, the light-emitting component includes a lamp tube, a reflector for focusing the light emitted by the lamp tube, a pair of first brackets for mounting the lamp tube, and a second mounting base for mounting the reflector. The lamp tube is disposed inside the reflector, and the opening of the reflector faces the light outlet. The filter is located on the opening side of the reflector, and the second mounting base is provided with a light-avoiding opening.

[0010] Furthermore, the second mounting base has a plurality of first slots on the side facing the lamp tube. The extended mounting portions at both ends of the reflector are engaged in the first slots to realize the installation of the reflector on the second mounting base. The second mounting base is provided with a second slot and a first limiting block. The first mounting base is provided with a second limiting protrusion that cooperates with the second slot. The first limiting block restricts the first mounting base from detaching from the second mounting base.

[0011] Furthermore, the cooling component is a semiconductor cooling component, with its lower surface directly bonded to the contact component and its upper surface directly bonded to end A of the heat-conducting component.

[0012] Furthermore, the heat-conducting component includes a heat-conducting element, which includes a first heat-conducting part and a second heat-conducting part arranged opposite to each other on the left and right, and an arc-shaped connecting part connecting the first heat-conducting part and the second heat-conducting part. A positioning plate is fixed at the bottom of the first heat-conducting part, and a plurality of heat dissipation plates are spaced apart on the outer periphery of the second heat-conducting part. The first heat-conducting part and the positioning plate constitute the A end of the heat-conducting component, and the second heat-conducting part and the plurality of heat dissipation plates constitute the B end of the heat-conducting component.

[0013] Furthermore, the heat dissipation component includes a fan and a fan mounting bracket for mounting the fan, with the second air outlet of the fan facing the B end of the heat conduction component and the light-emitting component.

[0014] Furthermore, the partition mounting base is provided with a contoured mounting groove for mounting the heat-conducting component, a first clearance opening for the heat of the light-emitting component to flow to the first air outlet, and a second clearance opening for the air from the fan to enter the B end of the heat-conducting component. A clearance space is provided between the bottom of the partition mounting base and the fan mounting base for the air from the fan to flow to the light-emitting component. A partition is provided between the first clearance opening and the contoured mounting groove, and the partition separates the heat of the light-emitting component from the heat of the B end of the heat-conducting component.

[0015] Furthermore, the outer shell includes an upper shell, a lower shell, a left shell, and a right shell that are spliced ​​together. The light outlet is located on the left shell, the first air outlet is located at the left end of the upper shell, the first air inlet and outlet are located at the right end of the upper shell, and the right shell is provided with a second air inlet.

[0016] Compared with existing technologies, the beneficial effects of this novel intense pulsed light therapy device are as follows: (1) Part of the fan air blows directly into the B end of the heat-conducting component through the second clearance opening. Due to the partition, the air flows directly out to the first air outlet through several ventilation gaps, forming the first airflow channel to dissipate heat at the B end of the heat-conducting component. Part of the fan air blows directly into the bottom of the light-emitting component through the clearance space between the bottom of the partition mounting base and the fan mounting base. At the same time, the air blows towards the entire length of the lamp tube and the reflector. Due to the partition, the air flows upward through the bottom of the reflector and flows directly out to the first air outlet, forming the second airflow channel to dissipate heat at the light-emitting component. The first airflow channel and the second airflow channel are independent of each other and perform heat dissipation at the same time. The two airflow directions will not interfere with each other. This not only solves the problem of airflow direction fluctuation affecting heat dissipation, but also improves the heat dissipation effect. (2) When the air is blown to dissipate heat in the second airflow channel, the air blows to the entire length of the lamp tube and the reflector at the same time. At this time, the airflow path is the shortest and the heat dissipation efficiency is higher. Moreover, since the fan blows to the entire length of the lamp tube and the reflector at the same time, the lamp tube heats up evenly, which can solve the problem that the lamp tube will have a reduced life due to uneven heating at different positions on the surface.

Detailed Implementation

[0018] Please refer to Figures 1-9This embodiment is an intense pulsed light therapy device 100. The intense pulsed light therapy device 100 includes a housing 1 and a control circuit board 2, a light-emitting component 3, a hair removal component 20, a cooling component 4, a heat-conducting component 5, and a heat dissipation component 6 disposed inside the housing 1. The control circuit board 2 is located at the bottom of the housing 1. A light outlet 10 is opened at one end of the housing 1. A first air outlet 11 is opened on the upper surface of the housing 1 near the light outlet 10, and a first air inlet / outlet 12 is opened on the upper surface of the housing 1 away from the light outlet 10. The light-emitting component 3 emits light into the light outlet 10. The cooling component 4 is disposed at the light outlet 10 for cooling and temperature reduction. The A end of the heat-conducting component 5 is clamped between the light outlet 10 and the light-emitting component 3. The light component 3 is sandwiched between the light-emitting component 3 and the heat dissipation component 6. The cooling component 4 contacts the A end of the heat-conducting component 5 to cool the A end of the heat-conducting component 5. At the same time, the heat-conducting component 5 will transfer the heat from the A end to the B end. A partition mounting seat 7 is provided between the heat dissipation component 6 and the light-emitting component 3 to form two airflow channels. The B end of the heat-conducting component 5 and the partition mounting seat 7 form a first airflow channel 8 to dissipate heat from the B end of the heat-conducting component 5. The light-emitting component 3 and the partition mounting seat 7 form a second airflow channel 9 to dissipate heat from the light-emitting component 3. The first airflow channel 8 and the second airflow channel 9 are independent of each other.

[0019] The hair removal component 20 is located at the light outlet 10. The hair removal component 20 includes a first mounting base 201, a filter 203 disposed on one side of the first mounting base 201, a contact 202 disposed on the other side of the first mounting base 201, and a trigger coil 204 mounted on the contact 202. In this embodiment, the contact 202 is made of sapphire. Using sapphire for ice-point hair removal carries low risk, is less likely to cause melanin deposition, and reduces inflammation. Sapphire's high transmittance and high refractive index can improve the speed of hair removal, shorten the treatment course, and avoid pain transmission. The trigger coil 204 excites and regulates light energy through electromagnetic induction, improving hair removal efficiency and ensuring safety. The filter 203 can filter harmful light. In this embodiment, the filter can only allow light with wavelengths of 600-12000nm. In other embodiments, filters 203 that can allow other wavelengths of light can be selected according to the actual situation; no limitation is made here.

[0020] The first mounting base 201 has a first mounting cavity 2011 for mounting the filter 203 on one side and a second mounting cavity 2012 for mounting the contact 202 and communicating with the first mounting cavity 2011 on the other side. In order to achieve positioning of the contact 202 and the filter 203 and prevent the contact 202 and the filter 203 from moving, a first limiting hook 2014 is provided on the outer side of the first mounting cavity 2011 to restrict the filter 203 from slipping. A first limiting protrusion 2013 is provided in the second mounting cavity 2012 to restrict the movement of the contact 202. Correspondingly, a first limiting groove 2021 that cooperates with the first limiting protrusion 2013 is provided on the outer wall of the contact 202.

[0021] Since the contact 202 is in direct contact with the skin, water vapor will be present on its surface during high-voltage discharge hair removal. To prevent water vapor from entering the interior of the outer casing 1 and causing electrical failure, a sealing element 205 is fitted around the filter 203. The sealing element 205 is made of rubber or silicone, which has high elasticity and good sealing effect. The filter 203 with the sealing element 205 is installed together into the first mounting cavity 2011. The sealing element 205 can prevent water vapor from entering the light-emitting component 3, heat dissipation component 6, etc. from the second mounting cavity 2012, thus avoiding the problem of electrical failure of the phototherapy device.

[0022] The light-emitting component 3 includes a lamp tube 31, a reflector 32 for focusing the light emitted by the lamp tube 31, a pair of first brackets 33 for mounting the lamp tube 31, and a second mounting base 34 for mounting the reflector 32. The lamp tube 31 is disposed inside the reflector 32, and the opening of the reflector 32 faces the light outlet 10. The filter 203 is located on the opening side of the reflector 32. The second mounting base 34 is provided with a light-avoiding opening 345.

[0023] The lamp tube 31 can emit light that can illuminate the hair follicles. The reflector 32 can enhance the light through reflection and improve the effect. After the lamp tube 31 is powered on, the light emitted is focused towards the opening at the front end inside the reflector 32, filtered by the filter 203 at the front end, and then irradiated outward from the light outlet 10 through the contact member 202 to perform the hair removal action.

[0024] The first bracket 33 is fixed on the control circuit board 2. The top of the first bracket 33 is provided with a fourth slot 331. The support shafts 311 at both ends of the lamp tube 31 are engaged in the fourth slot 331 to realize the installation of the lamp tube 31 on the first bracket 33.

[0025] The second mounting base 34 is fixed to both the control circuit board 2 and the housing 1 to ensure the stability of the light-emitting component. The second mounting base 34 has several first slots 341 on the side facing the lamp tube 31. The extended mounting portions 321 at both ends of the reflector 32 are engaged in the first slots 341 to realize the installation of the reflector 32 on the second mounting base 34.

[0026] To further ensure the stability of the installation of the lamp tube 31 and the reflector 32, the light-emitting component 3 also includes a limiting plate 35 that is snapped onto the outer wall of the lamp tube 31. The limiting plate 35 has a contoured notch 351 that conforms to the shape of the lamp tube 31 on one side and a limiting part 352 that is positioned in the first slot 341 at the upper end. The lamp tube 31 is snapped into the contoured notch 351, which can further support the lamp tube 31 and ensure the stability of the installation of the lamp tube 31. The limiting part 352 and the extended mounting part 321 are snapped together in the first slot 341, which can prevent the reflector 32 from moving back and forth and ensure the stability of the installation of the reflector 32.

[0027] The second mounting base 34 is provided with a second slot 342 and a first limiting block 343. The first mounting base 201 is provided with a second limiting protrusion 2016 that cooperates with the second slot 342. After the first mounting base 201 and the second mounting base 34 are installed in place, the first limiting block 343 will restrict the first mounting base 201 from detaching from the second mounting base 34.

[0028] The cooling component 4 is a semiconductor cooling component. The lower surface of the cooling component 4 is directly bonded to the contact 202, and the upper surface is directly bonded to the A end of the heat-conducting component 5. The cooling component 4 is positioned above the contact 202 and is directly bonded to the contact 202, thus playing a role in cooling. The A end of the heat-conducting component 5 is located above the cooling component 4 and is directly bonded to the cooling component 4. The A end of the heat-conducting component 5 can quickly remove the heat from the cooling component 4 and quickly transfer it to the B end of the heat-conducting component 5. The heat from the B end of the heat-conducting component 5 is then dissipated from the first air outlet 11 through the heat dissipation component 6.

[0029] The heat-conducting component 5 includes a heat-conducting element 51, which has a U-shaped structure and a hollow interior to further improve heat conduction efficiency. The heat-conducting element 51 includes a first heat-conducting part 511 and a second heat-conducting part 512 arranged opposite to each other, and an arc-shaped connecting part 513 connecting the first heat-conducting part 511 and the second heat-conducting part 512. A positioning plate 52 is fixed to the bottom of the first heat-conducting part 511, and several heat dissipation plates 53 are spaced apart on the outer periphery of the second heat-conducting part 512. The first heat-conducting part 511 and the positioning plate 52 constitute the A end of the heat-conducting component 5, and the second heat-conducting part 512 and the several heat dissipation plates 53 constitute the B end of the heat-conducting component 5.

[0030] The positioning plate 52 is provided with several positioning holes 521. Both the front and rear ends of the first mounting base 201 are provided with first positioning structures 2015 that cooperate with the positioning holes 521 for positioning. The first positioning structure 2015 can be a second positioning pin or a positioning post. The second positioning pin extends directly into the positioning hole 521, or a screw is tightened inside the positioning post to fix the positioning plate 52 to the first mounting base 201. The front and rear first positioning structures 2015 not only position the positioning plate 52 but also position the cooling component 4. The cooling component 4 is held in place within the first positioning structure 2015 to prevent movement. Wires extend from the cooling component 4 and connect to the control circuit board 2 to achieve electrical control of the cooling component 4.

[0031] The heat sinks 53 are arranged in parallel front and back, and a ventilation gap is provided between two adjacent heat sinks 53 for air to pass through. The heat sinks 53 are provided with through holes 531 that are similar in shape to the second heat-conducting part 512 to facilitate the installation and fixation between the heat sinks 53 and the second heat-conducting part 512. The arrangement of multiple heat sinks 53 can further improve the heat dissipation effect.

[0032] The heat dissipation assembly 6 includes a fan 61 and a fan mounting bracket 62 for mounting the fan 61. The fan mounting bracket 62 is mounted to the control circuit board 2 via a first positioning pin 63. The fan 61 is mounted to the fan mounting bracket 62 via a positioning post and screws. The second air outlet 611 of the fan 61 is directly facing the B end of the heat conduction assembly 5 and the light-emitting assembly 3. The second mounting bracket 34 is joined to the fan mounting bracket 62 from the left and right.

[0033] The partition mounting base 7 is positioned above the second mounting base 34 and the fan mounting base 62. The second mounting base 34 is provided with a third slot 344. The partition mounting base 7 is provided with a second limiting block 71 that cooperates with the third slot 344. The partition mounting base 7 is provided with a contoured mounting groove 72 for mounting the heat-conducting component 5, a first clearance opening 73 for the heat of the light-emitting component 3 to flow to the first air outlet 11, and a second clearance opening 75 for the air of the fan 61 to enter the B end of the heat-conducting component 5. A clearance space is provided between the bottom of the partition mounting base 7 and the fan mounting base 62 for the air of the fan 61 to flow into the light-emitting component 3. A partition 74 is provided between the first clearance opening 73 and the contoured mounting groove 72. The partition 74 separates the heat of the light-emitting component 3 from the heat of the B end of the heat-conducting component 5 so as to form two airflow channels.

[0034] A portion of the air from the second air outlet 611 of the fan 61 is blown directly into the B end of the heat-conducting component 5 through the second clearance opening 75. Due to the obstruction of the partition 74, the air flows directly out to the first air outlet 11 through several ventilation gaps, forming the first airflow channel 8 to dissipate heat from the B end of the heat-conducting component 5.

[0035] A portion of the airflow from the second air outlet 611 of fan 61 passes through the clearance space between the bottom of the partition mounting base 7 and the fan mounting base 62 and directly enters the bottom of the light-emitting component 3. Simultaneously, the airflow is directed along the entire length of the lamp tube 31 and the reflector 32. Due to the obstruction of the partition 74, the airflow flows upward through the bottom of the reflector 32 and directly exits to the first air outlet 11, forming a second airflow channel 9 to dissipate heat from the light-emitting component 3. In this case, the airflow path is the shortest, resulting in higher heat dissipation efficiency. Furthermore, because the airflow from fan 61 is directed along the entire length of the lamp tube 31 and the reflector 32, the lamp tube 31 receives uniform heat dissipation, solving the problem of uneven heating at different points on the lamp tube surface leading to a decrease in lamp tube lifespan.

[0036] The partition 74 provided on the partition mounting base 7 allows the B end of the heat-conducting component 5 to be enclosed with the partition mounting base 7 to form a first airflow channel 8 for heat dissipation of the B end of the heat-conducting component 5. It also allows the light-emitting component 3 to be enclosed with the partition mounting base 7 to form a second airflow channel 9 for heat dissipation of the light-emitting component 3. The first airflow channel 8 and the second airflow channel 9 are independent of each other and perform heat dissipation actions simultaneously. The two airflow directions will not interfere with each other, which not only solves the problem of airflow direction fluctuation affecting heat dissipation, but also improves the heat dissipation effect.

[0037] The outer casing 1 includes an upper casing 13, a lower casing 14, a left casing 15, and a right casing 16 that are spliced ​​together. The light outlet 10 is located on the left casing 15, the first air outlet 11 is located at the left end of the upper casing 13, and the first air inlet and outlet 12 is located at the right end of the upper casing 13. In order to further improve the heat dissipation effect, a second air inlet 17 is provided on the right casing 16 to allow more air to carry away the heat inside the outer casing 1.

[0038] A trigger capacitor 21 is soldered onto the control circuit board 2, and the trigger capacitor 21 is located at the right end of the outer casing 1.

[0039] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
