Description

Technical Field

[0001] The present application relates to the technical field of nursing equipment, and in particular to a nursing device and a nursing system. Background Art

[0002] With rising living standards, consumers are increasingly emphasizing beauty and skincare, leading to a growing popularity of various skincare products. Among these, hair removal devices are a particularly popular choice. These devices utilize a selective light source to emit high-energy light of a specific wavelength, which penetrates the hair follicles on the surface of the skin, destroying them and preventing them from regenerating.

[0003] During operation, the light-emitting components of hair removal devices generate a significant amount of heat. To ensure long-term, continuous use, a heat dissipation duct and fan are typically installed inside the device. The fan blows air into the heat dissipation duct, which then dissipates the heat generated by the light-emitting components out of the device's outlet, thereby achieving heat dissipation. However, in existing hair removal devices, heat dissipation through the heat dissipation duct is slow, resulting in low heat dissipation efficiency. Utility Model Content

[0004] The present application provides a nursing device, aiming to improve the heat dissipation efficiency of the nursing device.

[0005] In a first aspect, an embodiment of the present application provides a nursing device, comprising:

[0007] A heat generating component is arranged in the heat dissipation duct;

[0008] A working head is provided corresponding to the heating component, wherein the portion thereof in contact with the human body is exposed on the outer surface of the housing, and a first air inlet is configured on the outer surface of the housing;

[0009] A fan is arranged in the shell, the air inlet of the fan is connected to the first air inlet, the air outlet of the fan is connected to the end of the heat dissipation duct away from the air outlet, and at least one side of the heat dissipation duct is provided with a second air inlet connected to the outside.

[0010] During use of the nursing equipment of this embodiment, a low-pressure environment is formed due to the rapid flow of air in the heat dissipation duct, so that external low-temperature air is sucked into the heat dissipation duct through the second air inlet, and low-temperature air is continuously replenished into the heat dissipation duct, thereby accelerating the heat exchange between the heating component and the airflow, improving the heat dissipation speed of the heat dissipation duct, and effectively improving the heat dissipation efficiency of the nursing equipment.

[0011] In some embodiments, the heat dissipation duct includes a first duct segment and a second duct segment extending sequentially from the fan toward the air outlet, with the first duct segment having a larger cross-sectional area than the second duct segment. This embodiment increases the airflow velocity in the heat dissipation duct, allowing the airflow from the fan's air outlet to reach the outlet more quickly, effectively improving overall heat dissipation efficiency. Furthermore, it also increases the velocity of low-temperature external air drawn in through the second air inlet, further enhancing heat dissipation efficiency.

[0012] In some embodiments, the heating component is disposed in the second air duct section, thereby enabling faster heat exchange between the airflow and the heating component and improving heat exchange efficiency. Alternatively, the heating component is disposed between the first air duct section and the second air duct section, thereby achieving a more balanced heat dissipation effect for the heating component as a whole.

[0013] In some embodiments, the heat dissipation duct includes opposing sidewalls, at least one second air inlet is provided on the sidewall of the second air duct section, and the housing is provided with at least one air supply port connected to the second air inlet. This embodiment improves the speed at which air enters the heat dissipation duct from the second air inlet, thereby enhancing the heat dissipation effect of the nursing device.

[0014] In some embodiments, the air supply port and the first air inlet are respectively arranged on different sides of the shell; effectively avoiding the air intake interference between the first air inlet and the second air inlet of the heat dissipation duct, reducing noise, making the nursing equipment quieter during use, and having a better silent effect.

[0015] And / or, the second air inlet is arranged at one end of the second air duct section close to the first air duct section to achieve a better heat dissipation effect for the heat-generating component.

[0016] In some embodiments, the housing has an inwardly formed cavity located on a side of the fan away from the air outlet, with electronic components disposed in the cavity. The cavity is in communication with the fan's air inlet, and a third air inlet is disposed on the outer surface of the housing, in communication with the cavity. This embodiment further dissipates heat from the electronic components through the fan and the heat dissipation duct.

[0017] In some embodiments, the heat-generating component includes at least one light source and a reflector mounted within the heat dissipation duct. The light source is located on a side of the reflector facing away from the heat dissipation duct, and a ventilation space is formed between a sidewall of the reflector proximal to the heat dissipation duct and the sidewall of the heat dissipation duct. In this embodiment, airflow is directed through the ventilation space between the reflector and the sidewall of the heat dissipation duct, increasing airflow velocity and improving overall heat dissipation.

[0018] In some embodiments, one end of the reflector is opposite to the air outlet of the fan, and the other end is opposite to the air outlet; so that the airflow in the heat dissipation duct will contact both sides of the outer wall of the reflector at the same time, effectively ensuring the balance of the heat dissipation effect on both sides of the reflector, and facilitating part of the airflow to flow through the inner side of the reflector for heat exchange, thereby improving the heat dissipation effect.

[0019] And / or, one or more fins are provided on the side wall of the reflector close to the heat dissipation duct, and the fins are extended along the length direction of the shell; the contact area between the reflector and the airflow in the heat dissipation duct is increased, the heat exchange efficiency is greatly improved, and the heat dissipation effect is thereby improved.

[0020] In some embodiments, the light source is arranged along the length of the reflector, with both ends of the light source protruding from both ends of the reflector. The heating component further includes two light shields and two brackets mounted in the heat dissipation duct. The two light shields are respectively mounted on both ends of the light source, with a gap between the light shields and the end of the reflector adjacent thereto. The two ends of the light source are respectively fixed to the two brackets. The structural design of this embodiment improves the heat dissipation effect of the light source and the reflector.

[0021] In some embodiments, the heat dissipation duct is provided with an air guide extending from the air outlet toward the reflector to direct the air from the air outlet toward the light source and the area below the light source. This embodiment avoids power loss due to air dispersion and ensures a sufficiently high airflow velocity in the heat dissipation duct, thereby ensuring optimal heat dissipation.

[0022] In some embodiments, the first air inlet is arranged opposite to the air inlet of the fan, thereby reducing the wind resistance of the fan, thereby increasing the air outlet speed, and further improving the heat dissipation effect of the heat generating component.

[0023] And / or, the nursing device further comprises a heat dissipating element for ventilation, wherein the heat dissipating element is arranged between the air inlet of the fan and the first air inlet. In this embodiment, the fan also dissipates heat for the heat dissipating element.

[0024] In some embodiments, the heat sink is disposed on the fan's air inlet, and a first seal surrounding the air inlet is disposed between the fan's air inlet and the heat sink, with two sides of the first seal respectively in close contact with the fan and the heat sink. This embodiment allows more air entering the fan's air inlet to pass through the heat sink, removing more heat from the heat sink, thereby improving the heat dissipation effect of the heat sink.

[0025] In some embodiments, a second seal is provided at the joint between the air outlet of the fan and the heat dissipation duct, which effectively prevents air leakage from the air outlet of the fan, thereby reducing the pressure in the heat dissipation duct, and further reducing the air output and affecting the heat dissipation efficiency.

[0026] And / or, a dustproof net covering the air outlet is provided in the shell; the dustproof net effectively blocks external dust from entering the shell through the air outlet, thereby preventing dust from affecting the performance and heat dissipation effect of the heating component.

[0027] In a second aspect, an embodiment of the present application further provides a nursing system, comprising:

[0028] A nursing device as described above;

[0029] A charging component is selectively electrically connected to the nursing device; the charging component is used to power and / or charge the nursing device.

[0046] This application proposes a care device, such as a hair removal device, a skin care device, etc.

[0047] See Figures 1 to 5In this embodiment, the nursing device includes a shell 10, a fan 20, a heating component 30 and a working head 17; wherein, one end of the shell 10 (for the convenience of the following description, it is recorded as the first end 101) is provided with an air outlet 12, and the shell 10 is formed inwardly with a heat dissipation duct 13 connected to the air outlet 12; the fan 20 is arranged in the shell 10, the air inlet 21 of the fan 20 is connected to the first air inlet 11, and the air outlet 22 of the fan 20 is connected to the end of the heat dissipation duct 13 away from the air outlet 12, that is, the air outlet 12 and the air outlet 22 of the fan 20 are respectively connected to the opposite ends of the heat dissipation duct 13. Among them, the fan 20 can be a blower, an axial fan, or other types of fans 20; the first air inlet 11 can be set on any side of the shell 10, and it only needs to be connected to the air inlet 21 of the fan 20; in the figure of this embodiment, the fan 20 takes the blower type as an example, and the first air inlet 11 is set at the position of the air inlet 21 of the fan 20 on the shell 10 as an example.

[0048] refer to Figure 3 As shown by the dotted arrow in the figure, when the nursing device of this embodiment is working, the fan 20 inhales low-temperature air from the outside of the shell 10 from the first air inlet 11 through its air inlet 21, and blows the inhaled low-temperature air into the heat dissipation duct 13 from the air outlet 22. The low-temperature air blown into the heat dissipation duct 13 exchanges heat with the heating component 30, and after heat exchange, it becomes high-temperature air and quickly flows along the heat dissipation duct 13 to the air outlet 12 at the first end 101 of the shell 10, and finally blows out from the air outlet 12, thereby achieving heat dissipation and cooling of the heating component 30.

[0049] See Figure 7 , a second air inlet 133 communicating with the outside is provided on at least one side of the heat dissipation duct 13. Since the airflow in the heat dissipation duct 13 flows toward the air outlet 12 at high speed, the air pressure in the heat dissipation duct 13 will decrease, forming a low-pressure environment; in this embodiment, by adding a second air inlet 133 to the side wall of the heat dissipation duct 13, when the nursing device is in use, the heat dissipation duct 13 can draw the external low-temperature air into the heat dissipation duct 13 through the second air inlet 133 due to the low-pressure environment formed inside, and exchange heat with the heating component 30 faster, thereby achieving a better heat dissipation effect and effectively improving the heat dissipation efficiency of the nursing device. Among them, the number of the second air inlet 133 can be one or more, without specific limitation; the shape of the second air inlet 133 can be circular, triangular, or quadrilateral, without specific limitation.

[0050] In this embodiment, the heating component 30 is disposed in the heat dissipation duct 13 of the housing 10. The heating component 30 exchanges heat with the flowing air in the heat dissipation duct 13 to achieve heat dissipation and cooling. The heating component 30 can be any component in the nursing device that generates heat. For example, when the nursing device is a hair removal device, the heating component 30 can be one or more components including a light source 31 and a reflector 32. For another example, when the nursing device is a skin care device (such as a light skin care device or an electrode skin care device), the heating component 30 can be one or more components including a light bar and an electrode module.

[0051] Among them, the working head 17 is arranged corresponding to the heating component 30, and its part for contacting the human body is exposed on the outer surface of the shell 10; when the care device is a hair removal device, the working head 17 can be a pulse light output head for use close to the skin, and when the care device is a skin care device, the working head 17 can be an electrode skin care head, a light wave skin care head, etc. for use close to the skin. When the user uses the care device of this embodiment, care (such as hair removal or electrode stimulation, light wave irradiation, etc.) is performed by placing the part of the working head 17 exposed on the outer surface of the shell 10 against the area to be cared for by the skin. In some embodiments, the working head 17 can be provided on a side of the shell 10 adjacent to the first end 101 (such as the front of the shell 10), and the working head 17 can be set at a position adjacent to the first end 101. In this way, the length of the heat dissipation duct 13 can be effectively shortened, so that the heat of the heating component 30 can be more quickly sent out from the air outlet 12 of the first end 101, thereby greatly improving the heat dissipation effect. In some embodiments, the first air inlet 11 can be set on the side where the working head 17 is provided. In this way, when the user holds the nursing device in hand, the palm will not block the first air inlet 11, ensuring smooth air intake into the first air inlet.

[0052] The technical solution of the nursing device of this embodiment is to provide an air outlet 12 at one end of the shell 10, and the shell 10 forms a heat dissipation duct 13 inwardly connected to the air outlet 12, the air outlet 22 of the fan 20 in the shell 10 is connected to the end of the heat dissipation duct 13 away from the air outlet 12, the air inlet 21 of the fan 20 is connected to the first air inlet 11 of the shell 10, the heating component 30 is arranged in the heat dissipation duct 13, and at least one side of the heat dissipation duct 13 is provided with a second air inlet 133 communicating with the outside; when the nursing device is in use, the fan 20 inhales low-temperature air from the outside of the shell 10 through the air inlet 21 thereof from the first air inlet 11, and the The inhaled low-temperature air is blown into the heat dissipation duct 13 from the air outlet 22, and exchanges heat with the heating component 30. After the heat exchange, it becomes high-temperature air and quickly flows along the heat dissipation duct 13 to the air outlet 12, and is blown out from the air outlet 12 to achieve heat dissipation and cooling of the heating component 30; at the same time, a low-pressure environment is formed in the heat dissipation duct 13 due to the rapid flow of air flow, so that external low-temperature air is sucked into the heat dissipation duct 13 through the second air inlet 133, and low-temperature air is continuously added to the heat dissipation duct 13, which accelerates the heat exchange between the heating component 30 and the airflow, and improves the heat dissipation speed of the heat dissipation duct 13, that is, effectively improves the heat dissipation efficiency of the nursing equipment.

[0053] In some embodiments, a heat dissipation duct 13 can be provided extending along the length direction F of the housing 10, and the air outlet 12 and the air outlet 22 of the fan 20 are respectively connected to the two ends of the heat dissipation duct 13 in the length direction F of the housing 10, that is, the air outlet 22 of the fan 20 is directly connected to the air outlet 12 along the length direction F of the housing 10. Thus, the air blown out of the air outlet 22 of the fan 20 does not need to turn when passing through the heat dissipation duct 13 and then sent out of the housing 10 from the air outlet 12. This can greatly reduce the wind resistance of the airflow in the heat dissipation duct 13, greatly increase the airflow velocity in the heat dissipation duct 13, and allow the airflow to flow out of the heat dissipation duct 13 faster. In this way, when the nursing device is in use, the airflow in the heat dissipation duct 13 takes away more heat from the heating component 30 in the same period of time, that is, the heat of the heating component 30 is reduced faster, effectively improving the heat dissipation efficiency of the heating component 30 of the nursing device.

[0054] See Figure 3In some embodiments, the heat dissipation duct 13 includes a first duct segment 131 and a second duct segment 132, which are distributed sequentially from the fan 20 toward the air outlet 12. The ventilation cross-sectional area of the first duct segment 131 is larger than the ventilation cross-sectional area of the second duct segment 132. The ventilation cross-sectional area refers to the effective area of the cross-sectional area of the duct segment (the cross-sectional area refers to the cross-sectional area perpendicular to the length direction F of the housing 10) that can be used for airflow. The technical solution of the nursing device of this embodiment is to design the ventilation cross-sectional area of the first duct segment 131 to be larger than the ventilation cross-sectional area of the second duct segment 132. As a result, the airflow in the first duct segment 131 increases in velocity when it reaches the second duct segment 132. In this way, the airflow blown out from the air outlet 22 of the fan 20 can reach the air outlet 12 more quickly and be discharged, effectively improving the overall heat dissipation efficiency. In addition, the increase in the airflow velocity in the heat dissipation duct 13 also increases the speed of the low-temperature external air drawn in from the second air inlet 133, further improving the heat dissipation efficiency.

[0055] See Figure 3 In this embodiment, the heating component 30 is arranged in the second air duct section 132. Since the air flow velocity of the second air duct section 132 increases, the heat exchange speed between the air flow and the heating component 30 is faster and the heat exchange efficiency is higher.

[0056] In some embodiments, the heating component 30 can also be arranged between the first air duct section 131 and the second air duct section 132; for example, the first air duct section 131 and the second air duct section 132 are arranged at intervals, and the heating component 30 is arranged in the interval area between the two, or the first air duct section 131 and the second air duct section 132 are arranged continuously, and the heating component 30 is arranged at the junction of the first air duct section 131 and the second air duct section 132, part of the heating component 30 is located in the first air duct section 131, and the other part is located in the second air duct section 132. Since the farther the heat dissipation duct 13 is from the air outlet 22 of the fan 20, the higher the air flow temperature, therefore, if the air flow velocity at each location in the heat dissipation duct 13 is the same, the heat dissipation effect of the portion of the heating component 30 close to the air outlet 12 will be weaker than the heat dissipation effect of the portion of the heating component 30 close to the air outlet 22. By arranging the heating component 30 between the first air duct section 131 and the second air duct section 132, the air flow velocity around the heating component 30 becomes increasingly greater toward the air outlet 12, thereby improving the heat dissipation effect of the portion of the heating component 30 close to the air outlet 12. In this way, the overall heat dissipation effect of the heating component 30 is more balanced.

[0057] See Figure 7 and Figure 8The heat dissipation duct 13 includes opposing side walls, with at least one second air inlet 133 provided on the side wall of the second air duct section 132. The housing 10 is provided with at least one supplementary air inlet 14 connected to the second air inlet 133. Since the airflow from the first air duct section 131 increases its velocity when entering the second air duct section 132, the air pressure in the second air duct section 132 is reduced, creating an even lower low-pressure environment. This allows the second air duct section 132 to more quickly draw in low-temperature external air through the second air inlet 133. Furthermore, the provision of the supplementary air inlet 14 on the housing in communication with the second air inlet 133 further reduces the resistance to the inhalation of low-temperature external air through the second air inlet 133, increases the velocity of air entering the second air inlet 133 from the second air inlet 133, and thereby further enhances the heat dissipation effect. In some embodiments, two second air inlets 133 are provided, which are respectively provided on opposite sides of the side wall of the second air duct section 132, so that the air flow speed and state on both sides of the second air duct section 132 are similar, thereby maintaining a balanced heat dissipation effect on both sides of the second air duct section 132.

[0058] In some embodiments, the second air inlet 133 is arranged at one end of the second air duct section 132 close to the first air duct section 131. In this way, the low-temperature air entering from the second air inlet 133 can flow through a longer distance in the second air duct section 132 and exchange heat with the heating component 30 more fully. It can also ensure that the low-temperature air added has a heat dissipation effect on the part of the heating component 30 close to the first air duct section 131, thereby achieving a better heat dissipation effect.

[0059] In some embodiments, the supply air port 14 can be set at a position corresponding to the second air inlet 133. For example, the supply air port 14 can be set opposite to the second air inlet 133, so that the supply air port 14 can provide external air to the second air inlet 133 faster and smoother, reducing the resistance of air intake from the second air inlet 133 to the second air duct section 132, thereby achieving better heat dissipation effect.

[0060] In some embodiments, the air supply port 14 and the first air inlet 11 are located on different sides of the housing 10. For example, the first air inlet 11 is located on a side of the housing 10 adjacent to the side on which the air supply port 14 is located. In this embodiment, by disposing the air supply port 14 on a side of the housing 10 where the first air inlet 11 is not located, air intake interference between the first air inlet 11 and the second air inlet 133 of the heat dissipation duct 13 is avoided, thereby reducing noise and making the nursing device quieter and more silent during use.

[0061] See Figure 3 and Figure 4In some embodiments, the care device further includes a ventilation heat sink 40, which is disposed between the air inlet 21 of the fan 20 and the first air inlet 11. The heat sink 40 may be, for example, a radiator comprising a plurality of spaced-apart fins or a radiator having a grid-like structure. In this embodiment, the heat sink 40 may dissipate heat from the heating element 30 or other heat-generating components of the care device. For example, the heat sink 40 dissipates heat from the heating side of a cooling element in a hair removal device. The solution of this embodiment is to arrange the heat sink 40 between the first air inlet 11 and the air inlet 21 of the fan 20. When the nursing equipment is in use, the fan 20 draws external low-temperature air into the shell 10 from the first air inlet 11. The low-temperature air drawn into the shell 10 passes through the heat sink 40, takes away part of the heat on the heat sink 40 to form air with relatively high temperature, enters from the air inlet 21 of the fan 20, and is blown out from the air outlet 22 of the fan 20 into the heat dissipation duct 13, exchanges heat with the heating component 30 to increase the temperature, and finally forms high-temperature air and is discharged from the air outlet 12 to the outside of the shell 10.

[0062] In some embodiments, the first air inlet 11 is arranged relative to the air inlet 21 of the fan 20. In this way, external air enters the housing 10 through the first air inlet 11 to reach the air inlet 21 of the fan 20 without turning outward or changing direction, thereby reducing the air inlet resistance of the fan 20 and increasing the air inlet speed of the fan 20, thereby achieving better heat dissipation effect on the heat sink 40; at the same time, the air outlet speed is also correspondingly increased, thereby further increasing the air flow speed in the heat dissipation duct 13 and improving the heat dissipation effect of the heating component 30 of the nursing equipment.

[0063] See Figure 7 In some embodiments, the heat sink 40 is mounted on the air inlet 21 of the fan 20, and a first seal 71 is provided between the air inlet 21 of the fan 20 and the heat sink 40, surrounding the air inlet 21. The first seal 71 is positioned on either side of the heat sink 40, contacting the fan 20 and the heat sink 40. This first seal 71 allows more air entering the air inlet 21 of the fan 20 to pass through the heat sink 40, removing more heat from the heat sink 40 and improving the heat dissipation effect of the heat sink 40. The first seal 71 can be made of materials such as foam or silicone.

[0064] See Figure 7 In some embodiments, the interface between the air outlet 22 of the fan 20 and the heat dissipation duct 13 is sealed with a second seal 72. This prevents air leakage from the air outlet 22 of the fan 20, which could reduce the pressure in the heat dissipation duct 13 and, in turn, reduce the air volume and affect heat dissipation efficiency. The second seal 72 can be made of a material such as foam or silicone.

[0065] See Figure 3 、 Figure 4 and Figure 6 In some embodiments, the heating component 30 includes at least one light source 31 (two light sources 31 are used as an example in the figure of this embodiment), and a reflector 32 installed in the heat dissipation duct 13. The light source 31 is located on the side of the reflector 32 that is away from or facing away from the heat dissipation duct 13 (for convenience of description, it is recorded as the inner side of the reflector 32). A ventilation space is formed between the side wall of the reflector 32 that is close to or facing the heat dissipation duct 13 (for convenience of description, it is recorded as the outer side of the reflector 32) and the side wall of the heat dissipation duct 13. In the heating component 30 of this embodiment, the light source 31 generates a large amount of heat when in operation. The reflector 32 reflects the light from the light source 31 and absorbs most of the heat generated by the light source 31, reaching a very high temperature. Most of the air in the heat dissipation duct 13 passes through the ventilation space and exchanges heat with the outer wall of the reflector 32, thereby removing heat from the reflector 32 and achieving heat dissipation. In some embodiments, a portion of the airflow blown out of the air outlet 22 of the fan 20 may also flow through the space inside the reflector 32, exchanging heat with the light source 31 and the inner side of the reflector 32. For example, if the reflector 32 has a U-shaped or semicircular cross-section, a portion of the airflow blown out of the air outlet 22 of the fan 20 enters the reflector 32 from one end for heat exchange and exits from the other end of the reflector 32, thereby dissipating heat from the inner side of the reflector 32 and the light source 31. It should be noted that the figures of this embodiment only use the reflector 32 having a U-shaped cross-section as an example. The cross-sectional shape of the reflector 32 is not limited to a U-shape, and may also be a semicircular, V-shaped, W-shaped, or other shape that can converge or reflect light from the light source 31. The light source 31 may be a light-emitting element or component such as a lamp tube, a light bar, or a light bead.

[0066] In some embodiments, one end of the reflector 32 is opposite the air outlet 22 of the fan 20, and the other end is opposite the air outlet 12; that is, the reflector 32 is arranged along the longitudinal direction F of the housing, and the longitudinal direction F of the reflector 32 is substantially aligned with the longitudinal direction F of the housing (that is, the two directions may have a small angle, for example, less than 10°). In this way, when the airflow in the heat dissipation duct 13 flows through the ventilation space between the reflector 32 and the side wall of the heat dissipation duct 13, it will simultaneously contact both sides of the outer wall of the reflector 32, rather than first exchanging heat with one side of the outer wall of the reflector 32 and then reaching the other side of the outer wall of the reflector 32 for heat exchange. This effectively ensures a balanced heat dissipation effect on both sides of the reflector 32. In addition, the above-mentioned arrangement of the reflector 32 can also facilitate the partial air in the heat dissipation duct 13 to enter the reflector 32 from one end for heat exchange and exit from the other end of the reflector 32, thereby improving the heat dissipation effect.

[0067] In some embodiments, one or more fins 321 are provided on a side wall (i.e., an outer wall) of the reflector 32 that is adjacent to or faces the heat dissipation duct 13. The fins 321 extend along the length direction F of the housing. In this embodiment, by providing the fins 321 on the outer wall of the reflector 32, the contact area between the outer wall of the reflector 32 and the airflow in the heat dissipation duct 13 is increased, significantly improving heat exchange efficiency and thereby achieving enhanced heat dissipation. Furthermore, the fins 321 extend along the length direction F of the housing, aligning the airflow direction of the fins 321 with that of the heat dissipation duct 13. The fins 321 exert very little resistance to the airflow in the heat dissipation duct 13, thus preventing the fins 321 from significantly affecting the airflow velocity in the heat dissipation duct 13 and thereby affecting the overall heat dissipation efficiency. Among them, the reflector 32 can be fixed in the heat dissipation duct 13 by means of the fins 321 on its outer wall abutting against the inner wall of the heat dissipation duct 13. The reflector 32 can also be fixed in the heat dissipation duct 13 through other connecting parts or fixed in the heat dissipation duct 13 through other installation methods.

[0068] In some embodiments, the light source 31 is arranged along the length direction of the reflector 32, and the two ends of the light source 31 protrude from the two ends of the reflector 32. The heating component 30 also includes two light-blocking plates 34 and two brackets 33 installed in the heat dissipation duct 13. The two light-blocking plates 34 are respectively mounted on the two ends of the light source 31, and there is a gap between the light-blocking plates 34 and the end of the reflector 32 close to it. The two ends of the light source 31 are respectively fixed to the two brackets 33. In the solution of this embodiment, the bracket 33 of the light source 31 is arranged in the heat dissipation duct 13, so that the air flow can blow directly to the bracket 33, quickly taking away the heat of the bracket 33, thereby improving the heat dissipation effect of the light source 31; the two light-blocking plates 34 are respectively spaced from the corresponding ends of the reflector 32. While achieving the light-blocking effect, the air flow in the heat dissipation duct 13 can also be allowed to enter the reflector 32 from the gap between the end of the reflector 32 close to the air outlet 22 and the light-blocking plates 34 for heat exchange, and the air flow after heat exchange is blown out from the gap between the end of the reflector 32 close to the air outlet 12 and the light-blocking plates 34, thereby improving the heat dissipation effect of the reflector 32 and the light source 31.

[0069] See Figure 4 In some embodiments, the heat dissipation duct 13 is provided with an air guide 134 extending from the air outlet 22 of the fan 20 toward the reflector 32 to direct the air from the air outlet 22 of the fan 20 toward the light source 31 and the area below the light source 31. The air guide 134 guides the air from the air outlet 22 so that as much of the air as possible is directed toward the light source 31 and the area below it, avoiding power loss due to air dispersion and ensuring a sufficiently high airflow velocity in the heat dissipation duct 13, thereby ensuring an optimal heat dissipation effect.

[0070] See Figure 3 、 Figure 4 and Figure 8 In some embodiments, a cavity 15 is formed within the housing 10, located on a side of the fan 20 away from the air outlet 12. An electronic device 50 is disposed in the cavity 15 and communicates with the air inlet 21 of the fan 20. The housing 10 is provided with a third air inlet 16 communicating with the cavity 15. The third air inlet 16 is also provided at the second end 102 of the housing 10. The electronic device 50 may include a circuit board and components thereon, as well as other electrical components. Since the electronic device 50 also generates a small amount of heat during operation, this embodiment connects the cavity 15 containing the electronic device 50 to the air inlet 21 of the fan 20 and provides the third air inlet 16 on the outer surface of the housing 10, communicating with the cavity 15. When the nursing device is in use, hot air in the cavity 15 is drawn away by the fan 20, while the cavity 15 draws in cooler air from outside through the third air inlet 16, effectively dissipating heat from the electronic device 50. In some embodiments, the third air inlet 16 can be set at the second end 102 of the shell 10, wherein the first end 101 and the second end 102 are the opposite ends of the shell 10. In this way, when the user holds the care device for use, the third air inlet 16 will not be blocked by the holding hand, thereby ensuring the heat dissipation effect of the electronic device 50.

[0071] See Figure 3 In some embodiments, a dust screen 60 is provided within the housing 10 to cover the air outlet 12, and a sealing foam is provided on the dust screen 60. In this embodiment, the dust screen 60 provided at the air outlet 12 prevents external dust from entering the housing 10 through the air outlet 12, thereby keeping the interior of the housing 10 clean and preventing the heating component 30 from being covered by dust, which would affect its performance and heat dissipation. In addition, the sealing foam provided on the dust screen 60 prevents the hot air blown out of the air outlet 12 from flowing back into the housing 10 at the air outlet 12 and affecting the heat dissipation of the entire device.
