Description

Technical Field

[0001] This utility model relates to the field of medical aesthetics technology, and in particular to a main unit and skin care device for skin care. Background Technology

[0002] With the continuous improvement of people's living standards and the enhancement of their awareness of beauty and skincare, various skin care devices have gradually entered homes and professional beauty institutions, becoming important tools for daily skincare and beauty treatments. Skin care devices typically act on the skin through specific care components to achieve multiple care functions such as cleansing, absorption, firming, and skin rejuvenation, meeting the skincare needs of different groups of people.

[0003] Currently, most skin care devices on the market use a cylindrical structure, which has obvious limitations in heat dissipation design: the air inlet and outlet of the heat dissipation device lack reasonable spatial spacing and airflow guidance design, resulting in a short and disordered airflow circulation path inside the device. This not only significantly reduces the air intake efficiency, but also fails to form an efficient heat dissipation airflow channel, affecting the stability and service life of the care components. Utility Model Content

[0004] The main purpose of this utility model is to propose a main unit and skin care device for skin care equipment, aiming to solve the technical problem that the main unit of existing skin care equipment lacks reasonable space interval and airflow guidance design between the air inlet and outlet due to the straight cylindrical structure, resulting in short and disordered internal airflow circulation path, low heat dissipation efficiency, and affecting the stability and service life of the care components.

[0005] To achieve the above objectives, this utility model proposes a main unit for a skin care device, comprising:

[0006] The housing includes a grip portion and a mounting portion. The grip portion is arranged in a first direction, and the mounting portion is arranged in a second direction. The first direction and the second direction intersect. The grip portion has a first storage cavity and an air inlet communicating with the first storage cavity. The mounting portion has a second storage cavity and an air outlet communicating with the second storage cavity. The first storage cavity and the second storage cavity are interconnected to form an airflow channel.

[0007] A fan is disposed in the first receiving cavity, with the air inlet of the fan facing the air inlet and the air outlet of the fan connected to the airflow channel.

[0008] A nursing component is disposed in the second storage cavity. A heat dissipation channel is formed inside the nursing component. One end of the heat dissipation channel is connected to the airflow channel, and the other end of the heat dissipation channel is connected to the air outlet.

[0009] In some embodiments, the fan is located in the first storage cavity near the intersection of the handle and the mounting portion, and the air outlet is arranged toward the inlet of the second storage cavity.

[0010] In some embodiments, the central axis of the air outlet of the fan is arranged parallel to the central axis of the inlet of the second receiving cavity.

[0011] In some embodiments, the care component includes:

[0012] A bracket is disposed in the second storage cavity. The bracket is divided into a first chamber and a second chamber by a partition. The first chamber is connected to the airflow channel, and the second chamber is connected to the air outlet. At least one ventilation opening is provided on the partition. The ventilation opening passes through the partition and connects the first chamber and the second chamber to form the heat dissipation channel.

[0013] At least one light-emitting element is located in the first cavity and connected to the bracket, and the light-emitting element is arranged corresponding to the vent.

[0014] In some embodiments, the end face of the mounting portion adjacent to the grip portion is recessed to form a cavity for connecting the accessory head of the skin care device;

[0015] The second storage cavity includes side chambers located on both sides of the concave cavity, and a main chamber located on the side of the concave cavity away from the first storage cavity. The side chambers connect the first storage cavity and the main chamber. The nursing component is disposed in the main chamber, and the air outlet is connected to the main chamber.

[0016] In some embodiments, air guides are provided on both sides of the partition, and the air guides are provided with air inlets. The air inlets are connected to the opening at the end of the side chamber away from the first receiving chamber, and the cross-sectional area of ​​the air inlets gradually decreases along the airflow direction.

[0017] In some embodiments, the care assembly includes at least two light-emitting elements, and the support has a plurality of first chambers spaced apart, each first chamber corresponding to one of the light-emitting elements and accommodating one of the light-emitting elements, each first chamber communicating with a second chamber through a corresponding vent; and / or,

[0018] The ventilation opening is an elongated hole, and the light-emitting element is a tubular structure, with the length direction of the light-emitting element parallel to the length direction of the elongated hole.

[0019] In some embodiments, the care component further includes:

[0020] A reflector is provided on the outer periphery of the light-emitting element, and a light outlet is formed at the end of the reflector away from the partition.

[0021] The reflector is also provided with an opening corresponding to the ventilation opening, and the position of the opening is aligned with the position of the ventilation opening.

[0022] This utility model also provides a skin care device, including:

[0023] Host;

[0024] An accessory head, which is detachably connected to the main unit.

[0025] In some embodiments, the accessory head includes a housing and a heat sink. The housing has a protrusion adapted to the cavity. The protrusion is detachably embedded in the cavity. A heat dissipation cavity is formed inside the protrusion. The heat sink is disposed in the heat dissipation cavity. The housing has a heat dissipation port communicating with the heat dissipation cavity. When the protrusion mates with the cavity, both ends of the heat dissipation cavity are respectively connected to the first receiving cavity and the main chamber.

[0026] The skin care device main unit provided in this application divides the housing into a grip section and a mounting section arranged in intersecting directions. This allows the first storage cavity of the grip section and the second storage cavity of the mounting section to connect and form an orderly airflow channel. Combined with the spatial spacing design between the air inlet of the grip section and the air outlet of the mounting section, this effectively solves the problem of airflow turbulence caused by insufficient distance between the air inlet and outlet in traditional straight-cylinder structures. The fan efficiently draws in air from the air inlet through the air inlet end in the first storage cavity, and after being sent into the airflow channel through the air outlet end, it can flow directionally through the heat dissipation channel inside the care components, fully carrying away the heat generated by the operation of the care components, and finally expelling it from the air outlet, forming a complete and efficient airflow circulation. This structural design not only optimizes the airflow path and improves heat dissipation efficiency by utilizing the spatial layout of the housing, but also ensures the long-term stability of the care components through stable heat dissipation, extending the service life of the device. At the same time, the intersecting housing structure takes into account both the ease of gripping and the utilization of internal space. Attached Figure Description

[0041] Please refer to Figures 1 to 3 This application provides a main unit 100 for a skin care device, including a housing 10, a fan 20, and a care component 30.

[0042] The housing 10 includes a grip portion 11 and a mounting portion 12. The grip portion 11 is arranged in a first direction X, and the mounting portion 12 is arranged in a second direction Y. The first direction X and the second direction Y intersect. The grip portion 11 is provided with a first storage cavity 111 and an air inlet 112 communicating with the first storage cavity 111. The mounting portion 12 is provided with a second storage cavity 121 and an air outlet 122 communicating with the second storage cavity 121. The first storage cavity 111 and the second storage cavity 121 are interconnected to form an airflow channel.

[0043] The fan 20 is located in the first receiving cavity 111. The air inlet end of the fan 20 is opposite to the air inlet 112, and the air outlet end of the fan 20 is connected to the airflow channel.

[0044] The nursing component 30 is located in the second storage cavity 121. A heat dissipation channel is formed inside the nursing component 30. One end of the heat dissipation channel is connected to the airflow channel, and the other end of the heat dissipation channel is connected to the air outlet 122.

[0045] In this embodiment, the housing 10 serves as the basic support and airflow channel carrier for the skin care device 200. Its functions are divided into two parts: the grip part 11 is arranged along the first direction X and has a first storage cavity 111 inside, which provides an operating carrier that conforms to the user's gripping habits, and provides an air inlet for airflow circulation through the air inlet 112, while accommodating the fan 20 and providing it with a stable installation environment; the mounting part 12 is arranged along the second direction Y that intersects with the first direction X and has a second storage cavity 121 inside, which provides a precise installation space for the care components 30 on the one hand, and realizes the discharge of hot air through the air outlet 122 on the other hand, and constructs a complete airflow channel by communicating with the first storage cavity 111.

[0046] The fan 20 is located in the first receiving cavity 111 and serves as the power source for airflow circulation. Its air inlet end is positioned opposite to the air inlet 112, which can efficiently draw in external air. Its air outlet end is connected to the airflow channel, which can stably deliver air to the second receiving cavity 121, providing continuous airflow for heat dissipation of the care component 30.

[0047] The care component 30 is located in the second storage cavity 121 and is used to realize the skin care function. At the same time, it participates in heat dissipation through the heat dissipation channel opened inside: one end of the heat dissipation channel is connected to the airflow channel to receive air, and the other end is connected to the air outlet 122 to exhaust hot air, so that the air can flow through the inside of the care component 30 in a directional manner, and achieve rapid dissipation of its own heat without affecting the care function.

[0048] This embodiment effectively increases the spatial distance between the air inlet 112 and the air outlet 122 by dividing the housing 10 into a grip portion 11 and a mounting portion 12 arranged in intersecting directions. At the same time, the first storage cavity 111 of the grip portion 11 and the second storage cavity 121 of the mounting portion 12 are connected to form an orderly airflow channel. Combined with the spatial spacing design between the air inlet 112 of the grip portion 11 and the air outlet 122 of the mounting portion 12, the problem of airflow turbulence caused by insufficient distance between the air inlet 112 and the air outlet 122 in the traditional straight cylindrical structure is effectively solved.

[0049] The fan 20 efficiently draws in air through the air inlet 112 in the first receiving cavity 111, and after being sent into the airflow channel through the air outlet, it can flow directionally through the heat dissipation channel inside the care component 30, effectively removing the heat generated by the operation of the care component 30, and finally being discharged from the air outlet 122, forming a complete and efficient airflow cycle. This structural design not only optimizes the airflow path and improves heat dissipation efficiency by utilizing the spatial layout of the housing 10, but also ensures the long-term stability of the care component 30 through stable heat dissipation, extending the service life of the equipment. At the same time, the intersecting structure of the housing 10 takes into account both the ease of holding and the utilization rate of internal space.

[0050] In this embodiment, the types of skin care devices and the care components 30 have diverse correspondences. For example, common home skin care devices include facial cleansing devices, iontophoresis devices, radiofrequency skin tightening devices, photon skin rejuvenation devices, hot and cold compress devices, etc. Among them, the care components 30 of facial cleansing devices are mostly detachable silicone brush heads (used for physical friction to clean dirt from pores) or ultrasonic transducers (achieving deep cleansing through high-frequency vibration). The care components 30 of iontophoresis devices are often metal guide heads (used with skin care products to promote nutrient absorption through iontophoresis or ultrasonic action). The care components 30 of radiofrequency skin tightening devices are radiofrequency emission probes (releasing radiofrequency energy to stimulate collagen regeneration in the skin to achieve a tightening effect). The care components 30 of photon skin rejuvenation devices are generally LED light therapy modules (achieving skin rejuvenation, acne removal, and other functions through different wavelengths of red light, blue light, etc.).

[0051] In some embodiments, the fan 20 is located in the first storage cavity 111 near the intersection of the handle portion 11 and the mounting portion 12, and the air outlet is arranged toward the inlet direction of the second storage cavity 121.

[0052] In this embodiment, the fan 20 is located near the intersection of the first receiving cavity 111. This location, being close to the turning point of the airflow channel, reduces the resistance when the airflow turns. The air outlet is arranged towards the inlet of the second receiving cavity 121, which can directly guide the drawn-in air towards the second receiving cavity 121. This avoids the power waste caused by the diffusion of airflow in the first receiving cavity 111, improves the accuracy and speed of air delivery to the heat dissipation channel of the care component 30, and provides more efficient airflow support for the rapid heat dissipation of the care component 30.

[0053] After the fan 20 is started, it generates negative pressure to draw in external air. Because it is close to the intersection of the two parts and the air outlet is oriented towards the inlet of the second receiving cavity 121, it can directly and accurately deliver the air to the beginning of the airflow channel near the second receiving cavity 121. This shortens the air delivery distance from the fan 20 to the heat dissipation channel of the care component 30, reduces the loss and turbulence of the airflow during transmission, and allows the cold air to enter the care component 30 faster and more concentratedly, enhancing the airflow circulation efficiency and further solving the problem of long airflow transmission path and large loss in the existing structure.

[0054] In some embodiments, the central axis of the outlet end of the fan 20 is arranged parallel to the central axis of the inlet end of the second receiving cavity 121.

[0055] In this embodiment, the central axis of the air outlet of the fan 20 is parallel to the central axis of the inlet of the second receiving cavity 121, so that the airflow output by the fan 20 can be transported along a preset straight path, reducing the turning point of the airflow before entering the second receiving cavity 121, reducing the probability of airflow colliding with the internal structure of the housing 10, improving the straightness and stability of airflow transport, and providing a better initial state of airflow for subsequent entry into the heat dissipation channel.

[0056] The central axis of the inlet end of the second receiving cavity 121 is parallel to the central axis of the outlet end of the fan 20, forming a coaxial guiding structure. This provides a precise entry path for the airflow, avoiding phenomena such as airflow deviation and eddies at the inlet, and ensuring that the airflow can enter the interior of the second receiving cavity 121 completely and efficiently. At the same time, this parallel axis design also makes the position matching between the second receiving cavity 121 and the fan 20 more precise, simplifying the alignment process during assembly.

[0057] Please refer to Figure 3 and Figure 5 In some embodiments, the care component 30 includes a support 31 and at least one light-emitting element 32.

[0058] The bracket 31 is located inside the second storage cavity 121. The interior of the bracket 31 is divided into a first chamber 312 and a second chamber 313 by a partition 311. The first chamber 312 is connected to the airflow channel, and the second chamber 313 is connected to the air outlet 122. At least one ventilation opening 3111 is provided on the partition 311. The ventilation opening 3111 passes through the partition 311 and connects the first chamber 312 and the second chamber 313 to form a heat dissipation channel.

[0059] At least one light-emitting element 32 is located in the first chamber 312 and connected to the bracket 31. The light-emitting element 32 is correspondingly arranged with the vent 3111.

[0060] Among them, the bracket 31 serves as the core support and heat dissipation structure carrier of the nursing component 30. The internal space is divided into a first chamber 312 and a second chamber 313 by the partition 311, realizing the partitioned flow of airflow buffer, heat dissipation and exhaust, and avoiding the leakage of heat dissipation of the light-emitting element 32 caused by the airflow directly entering the air outlet 122 from the airflow channel. The first chamber 312 is connected to the airflow channel, providing a stable entry space for the straight airflow, and the second chamber 313 is connected to the air outlet 122, providing an exhaust path for the hot airflow. The ventilation port 3111 on the partition 311 precisely connects the two chambers to form a directional heat dissipation channel, and at the same time provides a positioning reference for the light-emitting element 32 (ensuring that the light-emitting element 32 corresponds to the ventilation port 3111), avoiding the airflow from bypassing the light-emitting element 32 and causing heat dissipation failure.

[0061] The light-emitting element 32 combines skin care functions with heat dissipation adaptation characteristics: Firstly, as a core component of phototherapy (such as LED skin rejuvenation lamps, acne removal lamps, etc.), it achieves skin care effects by emitting light of specific wavelengths; secondly, it is located in the first chamber 312 and corresponds to the vent 3111, so that the straight airflow delivered by the fan 20 can directly act on the surface of the light-emitting element 32, maximizing the absorption of its working heat; thirdly, it is connected and fixed to the bracket 31 to ensure stable position during equipment operation and avoid misalignment with the vent 3111 due to vibration, which would affect the heat dissipation effect.

[0062] In addition to separating the first chamber 312 and the second chamber 313, the partition 311 also guides airflow direction by opening ventilation openings 3111: on the one hand, it prevents the cold air in the first chamber 312 from directly entering the second chamber 313 without passing through the light-emitting element 32, and forces the airflow to flow through the light-emitting element 32; on the other hand, the diameter and number of ventilation openings 3111 can be adapted according to the heat generation power of the light-emitting element 32 to ensure that the heat dissipation airflow is matched with the heat dissipation requirements of the light-emitting element 32.

[0063] This embodiment utilizes the compartments of the bracket 31 to achieve precise heat dissipation by first cooling the light-emitting element 32 with airflow and then directing it out. This solves the problem of light efficiency attenuation caused by concentrated local heat and untimely heat dissipation in the light-emitting element 32 (such as a phototherapy component). At the same time, it works in synergy with the existing linear airflow system to further improve the targeted heat dissipation.

[0064] It should be noted that the compartmentalized design of the bracket 31 supports the assembly of multiple light-emitting elements 32 (multiple light-emitting elements 32 can be set in the first chamber 312 according to nursing needs, and multiple ventilation openings 3111 can be opened accordingly). At the same time, the aperture and number of ventilation openings 3111 can be adjusted as needed to adapt to the heat dissipation requirements of light-emitting elements 32 with different power, without the need to modify the existing structure such as the housing 10 and the fan 20, thus reducing the research and development and production difficulty of upgrading the equipment function.

[0065] Please refer to Figure 1 and Figure 4In some embodiments, the mounting portion 12 is recessed near the end face of the grip portion 11 to form a cavity 123 for connecting an accessory head of a skin care device;

[0066] The second storage cavity 121 includes side chambers 1211 located on both sides of the concave cavity 123, and a main chamber 1212 located on the side of the concave cavity 123 away from the first storage cavity 111. The side chambers 1211 connect the first storage cavity 111 and the main chamber 1212. The nursing component 30 is disposed in the main chamber 1212, and the air outlet 122 is connected to the main chamber 1212.

[0067] The recess 123 can be connected to the accessory head via a suitable snap-fit ​​or magnetic structure, enabling the expansion of care functions such as facial cleansing and massage. The depth of the recess 123 and the inner wall precisely match the size of the accessory head, ensuring connection stability. Furthermore, the recess 123 avoids the airflow channel area of ​​the side chamber 1211, preventing airflow blockage caused by the installation of the accessory head.

[0068] The side chambers 1211 are located on both sides of the concave cavity 123 and connect the first receiving cavity 111 and the main chamber 1212. They can evenly divide the concentrated airflow of the first receiving cavity 111 into two streams, avoiding turbulence caused by a single stream of air directly impacting the main chamber 1212. At the same time, the elongated structure of the side chambers 1211 can accelerate the airflow velocity, ensuring that the airflow reaches the main chamber 1212 efficiently. The main chamber 1212 serves as the core installation area of ​​the nursing component 30. Its spatial dimensions are adapted to the volume of the nursing component 30, and it is directly connected to the air outlet 122, allowing the hot airflow flowing through the nursing component 30 to be quickly discharged.

[0069] The cavity 123 design in this embodiment makes the device compatible with a variety of different types of attachments, enabling it to perform multiple functions (such as switching from phototherapy skin rejuvenation to deep cleansing). Compared with traditional single-function devices, it expands the usage scenarios of care and meets the diverse skin care needs of users.

[0070] Please refer to Figure 4 and Figure 5 In some embodiments, air guides 314 are constructed on both sides of the partition 311. The air guides 314 are provided with air guides 3141. The air guides 3141 are connected to the opening of the side chamber 1211 away from the first receiving chamber 111, and the cross-sectional area of ​​the air guides 3141 gradually decreases along the airflow direction.

[0071] Among them, the air guide section 314 serves as the airflow connection structure between the side chamber 1211 and the main chamber 1212, undertaking the dual functions of airflow guidance and pressurization: First, the contour of the air guide section 314 is adapted to the spatial layout of the outlet of the side chamber 1211 and the inlet of the main chamber 1212, which can wrap the airflow at the outlet of the side chamber 1211, preventing the airflow from leaking or diffusing at the connection, and ensuring that the airflow enters the air guide port 3141 completely; Second, the air guide port 3141 adopts a cross-sectional area gradient design, gradually reducing the channel size along the airflow direction, transforming the low-pressure airflow delivered by the side chamber 1211 into a high-pressure accelerated airflow, and improving the penetration of the airflow into the heat dissipation channel of the nursing component 30; Third, the precision design of the connection between the air guide port 3141 and the opening of the side chamber 1211 can calibrate the direction of the airflow entering the main chamber 1212, avoiding the airflow deviation that would cause local heat dissipation dead angles in the nursing component 30.

[0072] In this embodiment, the air guide 314 is constructed on both sides of the partition 311. The air guide 3141 opened therein is precisely connected to the opening at the end of the side chamber 1211 away from the first receiving chamber 111, so that the diverted airflow delivered by the side chamber 1211 can completely enter the air guide 3141. At the same time, the cross-sectional area of ​​the air guide 3141 gradually decreases along the airflow direction (from the side chamber 1211 to the main chamber 1212). According to the principle of fluid mechanics, when the airflow flows through the variable cross-section channel, the decrease in cross-sectional area will promote the increase of airflow velocity and wind pressure, forming a pressurized and accelerated airflow. This pressurized airflow is guided by the air guide 314 and can be directed to the heat dissipation channel inlet of the nursing component 30 in the main chamber 1212, solving the problem of insufficient heat dissipation coverage caused by diffusion and insufficient wind pressure after the traditional airflow enters the main chamber 1212.

[0073] In some embodiments, the air guide 314 can be integrated with the partition 311, achieving airflow pressurization without the need for additional power components (such as auxiliary fan 20), thus reducing equipment energy consumption and size. At the same time, the size of the air guide 314 is adapted to the existing layout of the side chamber 1211 and the main chamber 1212, without affecting the connection function of the recess 123 to the auxiliary head, and without requiring any changes to the original structure of the housing 10 and the care component 30, significantly reducing the production adaptation cost of technology upgrades.

[0074] Please refer to Figure 3 and Figure 5 In some embodiments, the nursing component 30 includes at least two light-emitting elements 32, and the support 31 has a plurality of first chambers 312 spaced apart inside. Each first chamber 312 corresponds to one light-emitting element 32 and accommodates one light-emitting element 32. Each first chamber 312 is connected to a second chamber 313 through a corresponding vent 3111; and / or,

[0075] Ventilation opening 3111 is an elongated hole, and light-emitting element 32 is a tubular structure. The length direction of light-emitting element 32 is parallel to the length direction of the elongated hole.

[0076] The bracket 31 is divided into multiple independent first chambers 312 by an interval structure. Each chamber precisely accommodates a light-emitting element 32, forming an independent heat dissipation unit with one lamp and one chamber, avoiding heat crosstalk between adjacent light-emitting elements 32. Moreover, each first chamber 312 has a corresponding ventilation opening 3111 to ensure that the pressurized airflow can be evenly distributed to each chamber, and there is no situation where some chambers have insufficient airflow.

[0077] The light-emitting element 32 adopts a tubular structure, which has a larger outer surface area compared with the traditional block structure. It can form multi-dimensional contact with the airflow and improve the heat exchange efficiency. Moreover, the length direction is parallel to the elongated vent 3111, which allows the airflow to flow smoothly along the length direction of the light-emitting element 32 and cover the entire cylindrical surface of the light-emitting element 32, avoiding heat dissipation dead zones caused by the airflow only acting on a local area.

[0078] The vent 3111 has an elongated hole structure, and the length of the elongated hole is parallel to the tubular light-emitting element 32. This can guide the airflow to flow in a preset direction, making the contact path between the airflow and the outer surface of the light-emitting element 32 more closely fit, and maximizing the heat exchange time.

[0079] Of course, in other embodiments, the light-emitting element 32 may also adopt a block-shaped, plate-shaped, or ring-shaped structure to adapt to different skin care scenarios; correspondingly, the vent 3111 may also be adjusted to a square, rectangular, or ring shape according to the structure of the light-emitting element 32, and always maintain the outline of the vent 3111 to match the outer outline of the light-emitting element 32, and the length / diameter direction of the vent 3111 to be consistent with the extension direction of the main heat dissipation surface of the light-emitting element 32, so as to ensure that the airflow can still fully cover the heat dissipation area of ​​the light-emitting element 32 without affecting the heat dissipation efficiency, while meeting the structural requirements of diverse care functions.

[0080] Please continue to refer to this. Figure 5 In some embodiments, the nursing component 30 also includes a reflector 33, which covers the outer periphery of the light-emitting component 32, and the end of the reflector 33 away from the partition 311 forms a light outlet 331.

[0081] The reflector 33 is also provided with an opening 332 corresponding to the ventilation opening 3111, and the position of the opening 332 is aligned with the position of the ventilation opening 3111.

[0082] In this embodiment, the reflector 33 can be made of a mirror material (such as an aluminum reflective film or an electroplated reflective layer) to cover the outer periphery of the light-emitting element 32, reflecting the radially diverging light from the light-emitting element 32 to the light outlet 331, forming a directional focusing effect and increasing the light irradiation intensity per unit area of ​​skin. Moreover, the covering structure of the reflector 33 forms physical protection for the light-emitting element 32, and at the same time, by fitting and installing it with the wall of the first chamber 312, it fixes the position of the light-emitting element 32, preventing vibration from causing misalignment between the light-emitting element 32 and the ventilation opening 3111 or the opening 332.

[0083] The opening 332 of the reflector 33 is precisely aligned with the vent 3111, so that the pressurized airflow delivered by the air guide 314 can enter the first chamber 312, act on the outer periphery of the light-emitting element 32, and then enter the second chamber 313 through the vent 3111 to be discharged, thus avoiding affecting the airflow.

[0084] In some embodiments, the aperture of the opening 332 of the reflector 33 is not smaller than the aperture of the vent 3111, ensuring that the pressurized airflow can enter the second chamber 313 without obstruction from the opening 332 and the vent 3111, and avoiding the reflector 33 from blocking the airflow path.

[0085] Please refer to Figure 6 This application also provides a skin care device 200, including a main unit 100 and an auxiliary head 201 as described above, wherein the auxiliary head 201 is detachably connected to the main unit 100. Since the skin care device 200 adopts all the technical solutions of all embodiments of the main unit 100 described above, the skin care device 200 of this utility model also possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.

[0086] Please refer to Figure 6 and Figure 7 In some embodiments, the accessory head 201 includes a housing 2011 and a heat sink 2022. The housing 2011 is constructed with a protrusion 2023 adapted to the cavity 123. The protrusion 2023 is detachably embedded in the cavity 123. A heat dissipation cavity 2024 is formed inside the protrusion 2023. The heat sink 2022 is disposed in the heat dissipation cavity 2024. The housing 2011 is provided with a heat dissipation port 2025 communicating with the heat dissipation cavity 2024. When the protrusion 2023 is engaged with the cavity 123, the two ends of the heat dissipation cavity 2024 are respectively connected to the first receiving cavity 111 and the main chamber 1212.

[0087] The outer casing 2011 serves as the basic support structure for the auxiliary head 201. Its protrusion 2023 is adapted to the shape and size of the cavity 123 of the main unit 100, ensuring the stability of the detachable connection between the two and providing a closed space for the heat dissipation cavity 2024. The heat dissipation vent 2025 is an airflow exchange channel between the heat dissipation cavity 2024 and the external environment, which can exhaust hot air. At the same time, the outer casing 2011 can isolate external dust and moisture, protect the internal heat sink 2022 and heat dissipation cavity 2024, and prevent impurities from affecting the heat dissipation efficiency.

[0088] The heat sink 2022 is located inside the heat dissipation cavity 2024. It can absorb the heat generated by the operation of the auxiliary head 201 (such as motor operation or heating component operation) through the metal thermal conductive material (such as aluminum alloy or copper), and provide a heat exchange carrier for the airflow, ensuring that the heat can be carried away by the airflow delivered by the host 100, and avoiding local overheating of the auxiliary head 201.

[0089] The concave cavity 123, through its fitting with the protrusion 2023, provides a precise installation reference for the auxiliary head 201, ensuring that after the protrusion 2023 is fitted, both ends of the heat dissipation cavity 2024 can be precisely connected with the first receiving cavity 111 and the main chamber 1212, thus preventing airflow leakage. While providing installation space for the fan 20, the first receiving cavity 111 distributes some of the pressurized airflow to the heat dissipation cavity 2024, providing airflow power for the integrated heat dissipation of the main unit 100 and the auxiliary head 201.

[0090] In this embodiment, the detachable design of the auxiliary head 201 and the main unit 100 meets diverse nursing needs. Simultaneously, through the adaptation of the heat dissipation cavity 2024, the radiator 2022, and the airflow system of the main unit 100, the auxiliary head 201 can dissipate heat while expanding its functions, avoiding the performance degradation or shortened lifespan problems caused by the lack of heat dissipation design in traditional detachable auxiliary heads 201. The adaptation structure between the protrusion 2023 of the auxiliary head 201 and the recess 123 of the main unit 100 does not require modification of the original core components of the main unit 100 (such as the fan 20, nursing component 30, and air guide 314). Connection and heat dissipation coordination are achieved simply by matching the dimensions of the recess 123 and the protrusion 2023. This design is compatible with different types and functions of auxiliary heads 201, reducing the cost of equipment function upgrades and production.

[0091] Furthermore, the heat dissipation design of the auxiliary head 201 effectively controls its operating temperature, avoiding the risk of skin discomfort or burns caused by overheating of the auxiliary head 201 during use. At the same time, the detachable connection structure is easy to operate, allowing users to easily replace the auxiliary head 201. The fit between the protrusion 2023 and the cavity 123 ensures that the auxiliary head 201 does not loosen during use, improving the stability of use.

[0092] The above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
