Abstract
Description
Technical Field
[0001] The present application relates to the technical field of skin care devices, and particularly to a care device and a care system. Background Art
[0002] At present, with the development of society, people pay more and more attention to skin beauty and care. As a result, a variety of care devices for skin care have emerged, such as hair removal devices, skin rejuvenation devices, wrinkle removal devices, etc.
[0003] The basic principle of the above-mentioned instruments is to achieve different skin care functions by irradiating different types of target light on the human skin. For example, the hair removal principle of a hair removal device is based on the photothermal lysis principle of intense pulsed light. Intense pulsed light (IPL), or pulsed intense light, is a broad-spectrum light formed by focusing and filtering a light source with a very high intensity. Since melanocytes in hair follicles can selectively absorb light of a specific wavelength range. And the IPL light emitted by the hair removal device can penetrate the epidermis and directly reach the hair follicles in the dermis. During this process, the light source component of the hair removal device conducts and emits light, and the light source component will emit a large amount of heat, causing the temperature of the contact part in contact with the user's skin at the light outlet of the hair removal device to rise sharply, posing a risk of scalding the user.
[0004] In the related art, a blower is provided to introduce cold air from the outside to dissipate heat from the light source component. However, the heat dissipation air duct of the hair removal device has many bends, large resistance, and low heat dissipation efficiency. Utility Model Content
[0005] The embodiments of the present application provide a care device and a care system, which can reduce the air duct resistance, shorten the air duct length, and improve the heat dissipation efficiency.
[0006] In a first aspect, the embodiments of the present application provide a care device, including:
[0007] A housing having a heat dissipation air duct and a first air inlet and an air outlet communicating with the heat dissipation air duct, the first air inlet being provided on the surface of the housing;
[0008] A blower disposed in the heat dissipation air duct, the air inlet side of the blower communicating with the first air inlet; and
[0009] A heating element at least partially disposed in the heat dissipation air duct and disposed between the air outlet side of the blower and the air outlet, so that the air flow introduced by the blower from the first air inlet flows through the heating element and is discharged from the air outlet.
[0010] By adopting the above technical solution, the fan can directly suck in external air from the first air inlet and then directly blow it to the heating element. This direct air flow path can quickly take away the heat generated by the heating element, reducing the number of turns of the air flow in the heat dissipation air duct. Since the air flow path is short and direct, the resistance and loss of the air flow in the heat dissipation air duct are reduced, improving the heat dissipation efficiency. After the air flow takes away the heat generated by the heating element, it is discharged from the air outlet, which can reduce the accumulation of heat in the housing, reduce the heat sensation of the housing, and improve the comfort of the user during use.
[0011] Optionally, the heating element and the first air inlet are located on the same surface of the housing.
[0012] By adopting the above technical solution, arranging the heating element and the first air inlet on the same surface can shorten the distance between the two, enabling the external air to quickly flow towards the heating element after flowing into the heat dissipation air duct, improving the heating efficiency; and this layout takes into account that when the user holds the care device, it reduces the possibility of accidentally blocking the first air inlet and maintains a stable air inflow.
[0013] Optionally, the number of the first air inlets is multiple, and the multiple first air inlets are located on the same surface or different surfaces of the housing.
[0014] By adopting the above technical solution, multiple first air inlets can increase the air flow rate on the air inlet side of the suction fan, enabling a continuous stream of air to flow into from the first air inlet in a timely manner, and more effectively taking away the heat from the heating element, improving the heat dissipation effect.
[0015] Optionally, the air outlet is arranged on the circumferential surface of the housing or on one side surface of the housing along the length direction.
[0016] By adopting the above technical solution, the position of the air outlet can be adjusted according to the layout position of the heating element in the housing to optimize the air flow path and ensure that the hot air is effectively discharged from the housing.
[0017] Optionally, the air outlet is arranged on one side surface of the housing along the length direction, and along the length direction of the housing, the heating element is arranged between the air outlet side of the fan and the air outlet.
[0018] By adopting the above technical solution, it is ensured that the air flow sucked by the fan flows through the heating element before being discharged from the air outlet, and shortening the distance between the air outlet and the heating element can reduce the time for heat to conduct in the housing, enabling the hot air to be guided to the air outlet for discharge more quickly, thereby improving the heat dissipation efficiency. This layout helps to directly and effectively guide the hot air flow from the heating element to the air outlet, reducing the twists and turns of the air flow inside the housing and reducing the wind resistance.
[0019] Optionally, along the length direction of the housing, the distance from the end of the first air inlet close to the bottom end of the housing to the bottom end of the housing is a first distance, the housing has a first length, and the ratio of the first distance to the first length is not less than 1 / 5.
[0020] By adopting the above technical solution, the distance between the first air inlet and the heating element is closer, and the external air inhaled by the fan can reach the heating area faster, improving the heat dissipation efficiency in the heat dissipation air duct; and it can reserve enough hand-held area for users, reducing the possibility of accidentally blocking the first air inlet during hand-held use, and reducing the risk of overheating of the nursing device caused by poor heat dissipation.
[0021] Optionally, the fan is a centrifugal fan, the air inlet side of the centrifugal fan is arranged opposite to the first air inlet, the air outlet side of the centrifugal fan is arranged opposite to the air outlet, an air inlet section of the heat dissipation air duct is formed between the first air inlet and the centrifugal fan, an air outlet section of the heat dissipation air duct is formed between the centrifugal fan and the air outlet, and the air inlet section is perpendicular to the air outlet section.
[0022] By adopting the above technical solution, the centrifugal fan can efficiently guide the air flow, can achieve direct blowing for heat dissipation, and improve the heat dissipation efficiency.
[0023] Optionally, the nursing device is a hair remover, and the heating element is the light-emitting component of the hair remover. The light-emitting component includes:
[0024] A light source, which is arranged in the heat dissipation air duct and is located between the air outlet side of the fan and the air outlet;
[0025] Wherein, an optical outlet opposite to the light source is further provided on the circumferential surface of the housing, and the optical outlet is used for the light emitted by the light source to penetrate out of the housing.
[0026] By adopting the above technical solution, the light source can output light energy, and the design of the optical outlet helps to concentrate and output the light emitted by the light source, improving the treatment effect of the hair remover.
[0027] Optionally, the light-emitting component and the fan are located on the same axial plane of the heat dissipation air duct.
[0028] By adopting the above technical solution, the air flow blown out from the air outlet side of the fan can directly blow towards the light-emitting component to avoid blocking. When the light-emitting component generates heat during operation, the heat can be directly and quickly taken away by the air flow, reducing the accumulation of heat on the surface of the light-emitting component, and realizing more direct and effective heat dissipation and cooling.
[0029] Optionally, the light-emitting component further includes:
[0030] The light source support is disposed within the heat dissipation air duct, between the air outlet side of the blower and the air outlet, and is connected to the light source to support the light source.
[0031] By adopting the above technical solution, the light source support provides stable support for the light source, ensuring that the light source remains fixed in position during the use of the nursing device and avoiding affecting the hair removal effect due to external vibrations. Moreover, the light source support can also prevent the high-intensity light emitted by the light source from directly irradiating the structure disposed on the side of the light source support away from the light source, reducing the risk of damage to the structure in this area due to overheating.
[0032] Optionally, the light-emitting component further includes:
[0033] A reflector, disposed at least on the side of the light source facing away from the light outlet.
[0034] By adopting the above technical solution, the reflector can reflect and focus the light emitted by the light source, ensuring that the light beam is output to the light outlet in a specific shape and direction, reducing light escape, concentrating more light on the hair removal area, and improving the hair removal efficiency. Moreover, the reflector can also prevent the high-intensity light emitted by the light source from directly irradiating the structure disposed on the side of the reflector away from the light source, reducing the risk of damage to the structure in this area due to overheating.
[0035] Optionally, the nursing device further includes:
[0036] Heat dissipation fins, disposed within the heat dissipation air duct and on the side of the reflector facing away from the light source.
[0037] By adopting the above technical solution, the heat dissipation fins help prevent local overheating of the light source and improve the heat dissipation efficiency by dispersing heat.
[0038] Optionally, the blower includes a blower housing and an impeller disposed within the blower housing, and the nursing device further includes:
[0039] An air guiding member, disposed between the blower and the heat dissipation fins to guide at least part of the air flow blown out by the blower towards the heat dissipation fins.
[0040] By adopting the above technical solution, the air guiding member is used to guide at least part of the air flow blown out by the blower directly towards the heat dissipation fins. By guiding the air flow, the distribution of the air flow within the device is improved, reducing turbulence and dead zones, increasing the surface area and contact time of the air flow with the heat dissipation fins, and improving the heat exchange efficiency.
[0041] Optionally, the light outlet and the first air inlet are disposed adjacent to each other on the same surface of the housing.
[0042] By adopting the above technical solution, the light outlet and the first air inlet are located on the same surface of the housing, which can also reduce the possibility that the user accidentally blocks the first air inlet when holding the care device during the use of the hair removal device, ensuring a continuous and stable airflow into the first air inlet. The adjacent arrangement of the light outlet and the first air inlet reduces the distance between the first air inlet and the light source, shortens the path length of the airflow reaching the light source, and ensures that the airflow can reach the light source faster after entering the first air inlet, achieving continuous and rapid heat dissipation.
[0043] Optionally, along the length direction of the housing, the light outlet is located between the first air inlet and the air outlet.
[0044] By adopting the above technical solution, it helps to form a linear airflow path, inhaling external air from the first air inlet, passing through the light source, and then discharging hot air from the air outlet, ensuring that the heat of the light source is quickly taken away after being generated, reducing the residence time of heat inside the device, and achieving efficient heat exchange.
[0045] Optionally, the housing has a convex portion, and the light outlet is arranged on the convex portion so that the light outlet is higher than the first air inlet.
[0046] By adopting the above technical solution, the light outlet needs to be pressed against the user's skin for lighting during use, and the convex portion can ensure that when the light outlet is in contact with the skin, the first air inlet will not be blocked by contacting the user's skin, that is, there is a certain space between the first air inlet and the user's skin, which can keep the air intake process of the first air inlet relatively unobstructed, and the fan can stably and smoothly inhale external air from the first air inlet to maintain the required airflow in the heat dissipation air duct.
[0047] Optionally, the air intake section of the heat dissipation air duct is formed between the first air inlet and the fan, and the air outlet section of the heat dissipation air duct is formed between the fan and the air outlet. The care device further includes:
[0048] A refrigerating element, arranged adjacent to the light outlet; and
[0049] A heat conducting element, in contact with the heat generating end of the refrigerating element and extending to the air intake section or the air outlet section.
[0050] By adopting the above technical solution, the refrigerating element can actively refrigerate. Compared with passive heat dissipation, it can reduce the temperature of the cold compress head more quickly. During the hair removal process, the synergistic effect of the refrigerating element and the cold compress head can reduce the heat on the skin surface. With its excellent cold conduction and cold storage characteristics, it can effectively ice the user's skin, improve the user's comfort, and achieve the purpose of relieving the pain and burning sensation of the user's skin during hair removal.
[0051] Optionally, a movement support is disposed inside the housing, and together with the housing, a heat dissipation air duct is configured. The blower and the heating element are disposed on the movement support; and
[0052] A first seal is disposed between the movement support and the blower to seal the gap between the movement support and the blower.
[0053] By adopting the above technical solution, the first seal is used to seal the gap between the movement support and the blower, preventing air flow from escaping through the gap between the movement support and the blower, ensuring that the air flow flows along a predetermined path, further improving the cooling effect on the heating element, and thus improving the overall heat dissipation efficiency.
[0054] Optionally, the housing includes a connecting shell and an end cover connected to the top of the connecting shell. The connecting shell has the first air inlet, and the end cover has the air outlet. The care device further includes:
[0055] A dust-proof net is disposed on the side of the end cover facing the heating element, and the orthographic projection of the dust-proof net on the air outlet covers the air outlet; and
[0056] A second seal is disposed between the end cover and the connecting shell to seal the gap between the end cover and the connecting shell, and is disposed around the periphery of the dust-proof net.
[0057] By adopting the above technical solution, the dust-proof net is used to prevent dust from entering the interior of the care device through the air outlet; the second seal is used to seal the gap between the end cover and the connecting shell, and the second seal is disposed around the periphery of the dust-proof net to prevent hot air from flowing back into the interior of the housing, avoiding an increase in the temperature inside the housing, and improving the stability and reliability of the care device.
[0058] Optionally, a second air inlet is provided at the bottom end or on the surface near the bottom end in the length direction of the housing. The second air inlet is communicated with the blower. The care device further includes:
[0059] An electronic device, which is disposed between the second air inlet and the blower.
[0060] By adopting the above technical solution, the blower introduces air flow from the second air inlet, creating a negative pressure space between the bottom end or the surface near the bottom end in the length direction of the housing and the blower. The electronic device is disposed in the negative pressure space. Providing the second air inlet can effectively dissipate heat from the electronic device, reduce damage to the electronic device caused by overheating, maintain the care device operating at a stable temperature, and improve the stability of the care device.

[0082] The realization, functional features and advantages of the object of the present application will be further described in conjunction with the embodiments with reference to the drawings. Detailed implementation manners
[0083] In order to make the object, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0084] Please refer to Figures 1 to 3 , the embodiment of the present application relates to a nursing device 100. At present, there are many types of nursing devices 100. Classified by function, nursing devices 100 usually include hair removal devices, beauty devices, radio frequency skin tightening devices, electromagnetic wave therapy devices, ultrasonic introduction devices, etc. The following takes the nursing device 100 as a hair removal device as an example to illustrate this embodiment. Other skin treatment devices such as radio frequency skin tightening devices, electromagnetic wave therapy devices, and ultrasonic introduction devices can be considered similarly.
[0085] A hair removal device is a device that uses light energy or laser technology for hair removal. Its main function is to irradiate the hair follicles with light energy or laser to destroy the melanin in the hair follicles, stop hair growth, and achieve the effect of permanent hair removal. The hair removal device includes a housing 10 and a blower 20 and a heating element 30 both arranged in the housing 10.
[0086] As the appearance component of the nursing device 100, the housing 10 can be designed to be handheld, which is convenient for users to hold and operate. The housing 10 can be made of plastic, which has the characteristics of being lightweight and having good insulation. It can also be made of metal, which has a certain structural strength and can protect the blower 20 and the heating element 30 inside it.
[0087] The heating element 30 is a key component (i.e., the following light-emitting component) that generates intense pulsed light in the hair removal device, and is responsible for emitting light with a specific wavelength and intensity to achieve the hair removal effect. To prevent the heating element 30 from overheating, the housing 10 has a heat dissipation air duct 10a (as shown by the dotted arrow in Figure 3 ), and the heating element 30 is arranged in the heat dissipation air duct 10a. The nursing device 100 further includes a blower 20 arranged in the heat dissipation air duct 10a. Arranging the blower 20 and the heating element 30 in the same heat dissipation air duct 10a can simplify the design and manufacture of the heat dissipation air duct 10a and reduce costs.
[0088] The housing 10 also has a first air inlet 10b and an air outlet 10c that communicate with the heat dissipation air duct 10a. The first air inlet 10b is provided on the surface of the housing 10. The air inlet side 20a of the fan 20 communicates with the first air inlet 10b, and the air outlet side 20b of the fan 20 is disposed opposite to the heat generating component 30, so that the air flow introduced by the fan 20 from the first air inlet 10b directly blows the heat generating component 30 and is discharged from the air outlet 10c. That is, the fan 20 directly sucks external air from the first air inlet 10b and then directly blows the heat generating component 30. This direct air flow path can quickly take away the heat generated by the heat generating component 30, reduce the number of turns of the air flow in the heat dissipation air duct 10a, and reduce the noise generated by the air flow. Since the air flow path is short and direct, the resistance and loss of the air flow in the heat dissipation air duct 10a are reduced, and the heat dissipation efficiency is improved. Moreover, after the air flow takes away the heat generated by the heat generating component 30, it is discharged from the air outlet 10c, reducing the accumulation of heat inside the housing 10, reducing the heat sensation of the housing 10, and improving the comfort of the user during use. In this embodiment, through effective heat dissipation, the performance degradation or failure of the nursing device 100 caused by overheating can be reduced, and the stability and reliability of the nursing device 100 are improved.
[0089] In some embodiments, the housing 10 further includes a main housing and an air inlet plate. The first air inlet 10b is provided on the air inlet plate. The air inlet plate and the main housing can be of a split design or an integral design. In the split design, the air inlet plate is detachably connected to the main housing, which is convenient for processing the first air inlet 10b on the air inlet plate. If the air inlet plate is damaged, in the split design, only the air inlet plate needs to be replaced instead of the entire housing 10, which helps to reduce the maintenance cost.
[0090] In some embodiments, the heat generating component 30 and the first air inlet 10b are located on the same surface of the housing 10. The heat generating component 30 and the first air inlet 10b being provided on the same surface can shorten the distance between the two, simplify the design of the internal air duct, reduce the manufacturing cost and complexity, and the heat generating component 30 being close to the first air inlet 10b can enable the external air to quickly flow to the heat generating component 30 after flowing into the heat dissipation air duct 10a, improving the heat generation efficiency and accelerating the heat dissipation speed. And this layout takes into account that when the user holds the nursing device 100, the possibility of accidentally blocking the first air inlet 10b is reduced, and a stable air inflow is maintained.
[0091] It can be understood that when the nursing device 100 is of other types, the heat generating component 30 can be a heat generating component corresponding to that type of nursing device 100. For example, the nursing device 100 can be a beauty instrument, and the heat generating component 30 can be a semiconductor refrigeration chip for cold compress. One end of the semiconductor refrigeration chip, that is, the cold end, refrigerates to achieve the cold compress function, and the other end, that is, the hot end, will dissipate heat. Therefore, the hot end of the semiconductor refrigeration chip can be directly blown by the above-mentioned fan 20 for heat dissipation.
[0092] To enhance the heat dissipation capacity of the nursing device 100, the number of the first air inlets 10b can be set to be multiple. The multiple first air inlets 10b can increase the air flow rate on the air inlet side 20a of the suction fan 20, so that a continuous stream of air can flow into the device from the first air inlets 10b in a timely manner, and more effectively take away the heat from the heat generating component 30. Moreover, the multiple first air inlets 10b can be located on the same surface or different surfaces of the housing 10. The positions of the first air inlets 10b can be set according to requirements. Setting them on the same surface may consider the convenience of users operating the device and avoid the user's hand blocking the first air inlets 10b, while setting them on different surfaces may consider the specific shape of the housing 10, and air inlets are set on different surfaces to adapt to its geometric characteristics and optimize the air flow path.
[0093] In some embodiments, the air outlet 10c is arranged on the circumferential surface of the housing 10 or on one side surface of the housing 10 along the length direction AA. The position of the air outlet 10c can be adjusted according to the layout position of the internal heat generating component 30 to optimize the air flow path and ensure that the hot air is effectively discharged from the housing 10.
[0094] In some embodiments, the air outlet 10c is arranged on one side surface of the housing 10 along the length direction AA. Along the length direction AA of the housing 10, the heat generating component 30 is arranged between the air outlet side 20b of the fan 20 and the air outlet 10c, ensuring that the external air flow inhaled by the fan 20 flows through the heat generating component 30 before being discharged. And shortening the distance between the air outlet 10c and the heat generating component 30 can reduce the time for heat to conduct in the housing 10, so that the hot air can be more quickly guided to the air outlet 10c for discharge, thereby improving the heat dissipation efficiency. This layout helps to directly and effectively guide the hot air flow from the heat generating component 30 to the air outlet 10c, reduce the twists and turns of the air flow inside the housing 10, and reduce the wind resistance. It also helps to reduce the swirling of the hot air inside the housing 10 and avoid the hot air recirculating back to the first air inlets 10b.
[0095] In some embodiments, the fan 20 can be a centrifugal fan. The centrifugal fan can efficiently guide the air flow. The air inlet side 20a of the centrifugal fan is arranged opposite to the first air inlets 10b, which is beneficial to shortening the distance from the air inlet side 20a of the centrifugal fan to the first air inlets 10b. The air outlet side 20b of the centrifugal fan is arranged opposite to the air outlet 10c, which is beneficial to shortening the distance from the air outlet side 20b of the centrifugal fan to the air outlet 10c. The centrifugal fan helps to directly transport the air flow from the first air inlets 10b to the air outlet 10c.
[0096] Furthermore, an inlet section of the heat dissipation air duct 10a is formed between the first air inlet 10b and the blower 20, and an outlet section of the heat dissipation air duct 10a is formed between the blower 20 and the air outlet 10c. The inlet section and the outlet section are perpendicular to each other, which further shortens the overall length of the heat dissipation air duct 10a, and there is only one turn in the heat dissipation air duct 10a. Compared with the related art, the perpendicular air duct design reduces the number of turns of the air flow in the heat dissipation air duct 10a, thereby reducing the resistance and pressure loss in the air duct, helping to form a direct and efficient heat exchange path, and thus quickly discharging the heat from the area of the heat generating component 30. Moreover, the perpendicular air duct reduces the space required for arranging the heat generating component 30 and the blower 20, which helps to achieve a more compact design of the care device 100.
[0097] Please refer to Figure 3 , in some embodiments, the heat generating component 30 is a light emitting assembly of a hair removal device. The light emitting assembly includes a light source 31, which can output light energy. The light source 31 is arranged in the heat dissipation air duct 10a and is located between the air outlet side 20b of the blower 20 and the air outlet 10c, ensuring that the air flow blown out from the air outlet side 20b of the blower 20 directly blows towards the light source 31, taking away the heat generated by the light source 31, preventing the light source 31 from overheating, reducing the risk of the user being scalded when using the care device 100, and improving the safety of use.
[0098] Specifically, the light emitting assembly and the blower 20 are located on the same axial plane CC of the heat dissipation air duct 10a (as Figure 6 shown), where the axial direction refers to the length direction AA of the housing 10. This axial plane CC passes through the light emitting assembly and the blower 20, meaning that the projections of the light emitting assembly and the blower 20 in this specified axial direction overlap, so that the air flow blown out from the air outlet side 20b of the blower 20 directly blows towards the light emitting assembly, avoiding occlusion. When the light emitting assembly generates heat during operation, the heat can be directly and quickly taken away by the air flow, reducing the accumulation of heat on the surface of the light emitting assembly, and achieving more direct and effective heat dissipation and cooling.
[0099] Furthermore, please refer to Figures 4 - 7 shown, the light emitting assembly further includes a light source bracket 32, which is connected to the end of the light source 31 to support the light source 31. The light source bracket 32 provides stable support for the light source 31, ensuring that the light source 31 remains fixed in position during the use of the care device 100, and avoiding affecting the hair removal effect due to external vibration.
[0100] The light source bracket 32 is disposed within the heat dissipation air duct 10a, that is, directly exposed in the heat dissipation air duct 10a, and is located between the air outlet side 20b of the blower 20 and the air outlet 10c. The light source bracket 32 includes a connected support member and a fixing member. The support member is in the shape of a thin rod to form a support. The fixing member has a U-shaped opening, and the end of the light source 31 is mounted on the U-shaped opening. In this way, the light source bracket 32 will not cause excessive blockage to the incoming flow on the air outlet side 20b of the blower 20, improving the smoothness of the air flow passing through the light source bracket 32, and the light source 31 can quickly transfer heat to the flowing air through the light source bracket 32, accelerating the heat dissipation process.
[0101] Please continue to refer to Figure 7 Moreover, in some embodiments, the circumferential surface of the housing 10 further has a light outlet 10d disposed opposite to the light source 31. The light outlet 10d is used for the light emitted by the light source 31 to pass through the housing 10. The light outlet 10d and the first air inlet 10b are located on the same surface of the housing 10 and are adjacent to each other, that is, the distance between the first air inlet 10b and the light source 31 is reduced, and the path length of the air flow reaching the light source 31 is reduced, ensuring that the air flow can reach the light source 31 faster after entering the first air inlet 10b, realizing continuous and rapid heat dissipation. In addition, the light outlet 10d and the first air inlet 10b are located on the same surface of the housing 10, which can also reduce the possibility that the user accidentally blocks the first air inlet 10b when holding the care device 100 during the use of the hair removal device, ensuring a continuous and stable air flow into the first air inlet 10b.
[0102] Furthermore, the light outlet 10d is located between the first air inlet 10b and the air outlet 10c, which helps to form a linear air flow path, sucking external air from the first air inlet 10b, passing through the light source 31, and then discharging the hot air from the air outlet 10c, ensuring that the heat of the light source 31 is quickly taken away after being generated, reducing the residence time of the heat inside the device, and realizing efficient heat exchange.
[0103] Please continue to refer to Figure 7, the light-emitting component further includes a reflector 33 and heat dissipation fins 34. The reflector 33 is at least disposed on the side of the light source 31 facing away from the light outlet 10d. Understandably, the reflector 33 has a bottom and a side, and is semi-surroundingly disposed outside the light source 31. The reflector 33 can reflect and focus the light emitted by the light source 31, ensuring that the light beam is output to the light outlet 10d in a specific shape and direction, reducing light escape, concentrating more light on the hair removal area, and improving the hair removal efficiency. The heat dissipation fins 34 are disposed in the heat dissipation air duct 10a and on the side of the reflector 33 facing away from the light source 31, that is, connected to the bottom and side of the reflector 33. The heat dissipation fins 34 have a plurality of sheet-like structures, and heat dissipation gaps are formed between adjacent sheet-like structures, which can increase the surface area in contact with air. The heat dissipation fins 34 help prevent local overheating of the light source 31 and improve the heat dissipation efficiency by dissipating heat. Among them, the reflector 33 and the heat dissipation fins 34 can be of an integral structure or a split structure.
[0104] In some embodiments, as Figures 8 to 10 shown, the blower 20 includes a blower housing 21 and an impeller 22 disposed in the blower housing 21. The care device 100 further includes a wind guiding member (not shown in the figure). The wind guiding member is disposed between the blower housing 21 and the heat dissipation fins 34 to guide at least part of the air flow blown out by the blower 20 directly to the heat dissipation fins 34. By guiding the air flow, the distribution of the air flow inside the device is improved, turbulence and dead zones are reduced, the surface area and contact time of the air flow in contact with the heat dissipation fins 34 are increased, and the heat exchange efficiency is improved.
[0105] Specifically, as Figure 2 shown, along the length direction AA of the housing 10, the distance from the edge of the first air inlet 10b close to the bottom end of the housing 10 to the bottom end of the housing 10 is the first distance L1. The housing 10 has a first length L2. The ratio of the first distance L1 to the first length L2 is not less than 1 / 5, so that the first air inlet 10b is closer to the light source 31. By reducing the distance from the first air inlet 10b to the light source 31, the external air inhaled by the blower 20 can reach the heating area faster, and the heat dissipation efficiency in the heat dissipation air duct 10a is improved.
[0106] And defining that the ratio of the first distance L1 from the first air inlet 10b to the bottom end of the housing 10 to the first length L2 of the housing 10 is not less than 1 / 5 can reserve enough holding area for the user, reduce the possibility of accidentally blocking the first air inlet 10b during handheld use, and reduce the risk of overheating of the care device 100 caused by poor heat dissipation.
[0107] Please continue to refer to Figure 7, Further, the housing 10 has a convex portion 11, and the light outlet 10d is provided on the convex portion 11 so that the light outlet 10d is higher than the first air inlet 10b. In actual use, the light outlet 10d needs to be pressed against the user's skin for lighting, and the convex portion 11 can ensure that when the light outlet 10d is in contact with the skin, the first air inlet 10b will not be blocked by contacting the user's skin, that is, there is a certain space between the first air inlet 10b and the user's skin, which can keep the air intake process of the first air inlet 10b relatively unobstructed, and the fan 20 can stably and smoothly suck in external air from the first air inlet 10b to maintain the required air flow in the heat dissipation air duct 10a.
[0108] Please continue to refer to Figure 7 , In some embodiments, the light emitting assembly further includes a filter 35 and a cold compress head 36 disposed in the light outlet 10d. The cold compress head 36, the filter 35, and the light source 31 are stacked in sequence from outside to inside and cooperate with each other to improve the hair removal efficiency. The filter 35 can filter out light of a specific wavelength emitted by the light source 31 and only allow light of a specific wavelength to pass through, improving the hair removal effect, while the cold compress head 36 can provide a cooling effect on the user's skin, reduce the discomfort during the hair removal process, and lower the temperature of the skin surface to reduce the risk of thermal damage.
[0109] Specifically, the cold compress head 36 is made of sapphire. Sapphire has the advantages of high heat transfer coefficient and high light transmittance. Due to the high heat transfer coefficient of sapphire, the light-transmitting crystal made of sapphire has excellent cold conduction and cold storage characteristics.
[0110] Please continue to refer to Figure 7 , In some embodiments, the care device 100 further includes a refrigerating member 40 and a heat conducting member 50. The refrigerating member 40 is disposed adjacent to the light outlet 10d, specifically on the side of the cold compress head 36. The refrigerating member 40 can actively refrigerate, and compared with passive heat dissipation, it can reduce the temperature of the cold compress head 36 more quickly. During the hair removal process, the cooperative effect of the refrigerating member 40 and the cold compress head 36 can reduce the heat on the skin surface. With its excellent cold conduction and cold storage characteristics, it can effectively ice the user's skin, improve the comfort of the user, and achieve the purpose of alleviating the pain and burning sensation of the skin during hair removal, thus optimizing the user's experience when using the hair removal device for hair removal.
[0111] The heat conducting member 50 is in contact with the heat generating end of the refrigerating member 40 and extends to the air inlet section or the air outlet section of the heat dissipation air duct 10a, so that the heat conducting member 50 contacts the air flow in the air inlet section or the air outlet section, that is, the air flow flowing in from the first air inlet 10b can simultaneously dissipate heat from the heat conducting member 50. There is no need to separately set up a new heat dissipation air duct 10a, which simplifies the structure, reduces the additional energy consumption caused by poor heat dissipation, and realizes energy conservation and environmental protection.
[0112] Further, asFigure 5 and Figure 6 As shown in Figure 6 , the heat conducting member 50 is a heat conducting copper tube. The nursing device 100 further includes a plurality of heat sinks 90. The plurality of heat sinks 90 are spaced and embedded at the end of the heat conducting copper tube away from the refrigerating member 40. The plurality of heat sinks 90 are arranged between the air inlet side 20a of the blower 20 and the first air inlet 10b. The plurality of heat sinks 90 can increase the surface area of the heat conducting copper tube in contact with the air, improve the heat exchange efficiency, and the heat sinks 90 contribute to guiding the air flow through the heat conducting copper tube and improving the heat dissipation performance.
[0113] As Figure 6 shown in Figure 6 , in some embodiments, the nursing device 100 further includes a filter screen 91. The filter screen 91 is arranged between the first air inlet 10b and the plurality of heat sinks 90. The filter screen 91 can block dust and other particles from entering the interior of the housing 10, which helps to protect the heating member 30 and the electronic devices 80 inside the housing 10, especially the more sensitive electronic devices 80, from performance degradation caused by dust. At the same time, it helps to keep the heat dissipation system operating efficiently and avoid the decline of heat dissipation performance caused by dust accumulation.
[0114] As Figure 8 and Figure 9 shown in Figure 9 , in some embodiments, the nursing device 100 further includes a movement support 60 and a first seal (not shown in the figure). The movement support 60 is arranged inside the housing 10 and together with the housing 10 defines a heat dissipation air duct 10a. The blower 20 and the heating member 30 are both arranged on the movement support 60. The movement support 60 provides a stable installation platform for the blower 20 and the heating member 30, ensuring that the positions of the blower 20 and the heating member 30 are fixed and do not shift during the user's use of the nursing device 100. The first seal is arranged between the movement support 60 and the blower 20 to seal the gap between the movement support 60 and the blower 20, preventing the air flow from escaping through the gap between the movement support 60 and the blower 20, ensuring that the air flow flows along the predetermined path, further improving the cooling effect on the heating member 30, and thus improving the overall heat dissipation efficiency. Setting the first seal can avoid air leakage from the heat dissipation air duct 10a, reducing the air duct pressure and resulting in a decrease in the air output volume and affecting the heat dissipation efficiency.
[0115] Specifically, as Figure 8 and Figure 9 shown in Figure 9 , the movement support 60 includes a top plate 61 and a bottom plate 62. The top plate 61 is connected to the bottom plate 62 and together with the bottom plate 62 defines an installation groove 63 and a communication port 64. The installation groove 63 is used to provide an installation space for the light source 31. Along the length direction of the bottom plate 62, the blower 20 is further installed on the bottom plate 62. The communication port 64 communicates the installation groove 63 and the air outlet side 20b of the blower 20, so that the air outlet side 20b of the blower 20 can directly face the light source 31 in the installation groove 63, guiding the flow direction of the air flow and ensuring that the air flow flows along the predetermined path.
[0116] Please refer to Figure 3 In some embodiments, a second air inlet 10e is provided at the bottom end or on the surface near the bottom end of the housing 10 in the longitudinal direction AA. The second air inlet 10e is communicated with the fan 20. The fan 20 introduces air flow from the second air inlet 10e, so as to form a negative pressure space between the bottom end or the surface near the bottom end of the housing 10 in the longitudinal direction AA and the fan 20. The care device 100 further includes an electronic component 80. The electronic component 80 is disposed between the second air inlet 10e and the fan 20, that is, the electronic component 80 is disposed in the negative pressure space. Providing the second air inlet 10e can effectively dissipate heat from the electronic component 80, reduce damage to the electronic component 80 caused by overheating, maintain the care device 100 operating at a stable temperature, and improve the stability of the care device 100.
[0117] Specifically, the electronic component 80 may include a circuit board and capacitors connected to the circuit board. The care device 100 may further include a touch screen. The touch screen is disposed on the bottom surface of the housing 10 in the longitudinal direction AA. The touch screen is used to display the device status and related information of the care device 100, facilitating the user to intuitively view and operate the touch screen. The touch screen is electrically connected to the circuit board. The user can touch the touch screen to turn on or off the care device 100, and adjust functions such as the light output power of the care device 100, providing a personalized operation experience.
[0118] In some embodiments, the electronic component 80 is disposed on the side of the light source bracket 32 away from the light source 31, and on the side of the light source 31 away from the reflector 33. The light source bracket 32 and the reflector 33 can prevent the high-intensity light emitted by the light source 31 from directly irradiating the electronic component 80, reducing the risk of damage to the electronic component 80 due to overheating.
[0119] In some embodiments, as Figure 7 shown, the housing 10 includes a connecting shell 12 and an end cover 13 connected to the top end of the connecting shell 12. The connecting shell 12 has a first air inlet 10b, and the end cover 13 has an air outlet 10c. The care device 100 further includes a dust-proof net 70. The dust-proof net 70 is disposed on the side of the end cover 13 facing the heating element 30, and the orthographic projection of the dust-proof net 70 on the air outlet 10c covers the air outlet 10c. The dust-proof net 70 can prevent dust from entering the interior of the care device 100 through the air outlet 10c, avoiding the care device 100 from malfunctioning due to dust accumulation or poor heat dissipation of the care device 100.
[0120] Further, to prevent the hot air blown out from the air outlet 10c from flowing back, the care device 100 further includes a second seal (not shown in the figure). The second seal is disposed between the end cap 13 and the connection shell 12 to seal the gap between the end cap 13 and the connection shell 12, and the second seal surrounds the periphery of the dust-proof net 70 to prevent the hot air from flowing back from the air outlet 10c to the inside of the housing 10, avoiding the increase in the temperature inside the housing 10 and improving the stability and reliability of the care device 100.
[0121] In some embodiments, as Figure 11 shown, the present application further provides a care system. The care system includes a charging component 200, and the charging component 200 can be selectively electrically connected to the care device 100; the charging component 200 is used to supply power to and / or charge the care device 100, and one or more charging ports can be provided on the care device 100 to make the care system adapt to multiple methods, improving the versatility of the care system.
[0122] In some alternative embodiments, the care device 100 may further include a wireless charging module, and the charging component 200 supplies power to or charges the care device 100 in a wireless charging manner, improving the convenience of use of the care device 100.
[0123] In some embodiments, the care system further includes a control device 300. The control device 300 is electrically arranged with the blower 20 and the heating element 30. The control device 300 is disposed inside the housing 10 of the care device 100 or is separately arranged from the care device 100; when the control device 300 is separately arranged from the care device 100, the control device 300 is communicatively connected to the care device 100 in a wired or wireless manner, and the wireless connection method includes but is not limited to Bluetooth connection and local area network communication connection. The separate arrangement of the control device 300 and the care device 100 can achieve the miniaturization of the care device 100.
[0124] In some embodiments, the care system further includes a placement bracket for storing the care device 100, avoiding situations such as dropping, tipping, sliding, and rolling that may occur when the care device 100 is placed, ensuring the stable placement of the care device 100, reducing the damage to the care device 100 caused by improper placement, and helping to extend the service life of the care device 100.
[0125] In some embodiments, the care system further includes a protective cover for protecting the heating element 30 of the care device 100. The protective cover can be a transparent or opaque cover body, and protects the heating element 30 of the care device 100 by covering the heating element 30. The protective cover can reduce the risk of damage to the heating element 30 due to accidental impact or scratching.
[0126] In some alternative embodiments, the protective cover can be made of elastic material or inelastic material. The protective cover with certain elasticity can absorb minor impacts and vibrations, providing additional buffer protection for the heating element. The inelastic material is not easily deformed due to environmental changes (such as temperature changes), maintaining stable protective performance.
