Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, and in particular to a solar-powered hair dryer with dual air ducts. Background Technology

[0002] Hair dryers, as a common small household appliance, are widely used in daily life, primarily for drying hair or drying objects. With continuous technological advancements, hair dryers are no longer limited to simple air blowing; some now incorporate light-powered functions. These hair dryers typically integrate halogen lamps or other light sources into the traditional design. Halogen lamps emit light of specific wavelengths, which can assist in additional functions such as scalp care and promoting blood circulation. Furthermore, halogen lamps also generate heat. The wavelengths and heat from these light sources are considered healthier, thus meeting consumers' diverse needs for hair dryer functions.

[0003] In existing designs of hair dryers with solar energy capabilities, the internal structural layout plays a crucial role in the product's performance and stability. The main air duct and the halogen lamp's heat dissipation channel are two key structural components. The main air duct is responsible for guiding the airflow generated by the hair dryer motor, causing it to pass through the heating element and become hot air before being blown out to achieve the drying function. Meanwhile, the halogen lamp generates a significant amount of heat during operation, requiring an effective heat dissipation channel to dissipate this heat, ensuring the halogen lamp operates at its normal operating temperature and extending its lifespan.

[0004] However, current solar-powered hair dryers have a significant structural design flaw: the main air duct is not separated from the halogen lamp's heat dissipation channel. In this layout, when the heating element in the main air duct is operating, the airflow intended for cooling the halogen lamp is inevitably affected by it. Specifically, the heat generated by the heating element is transferred to the surrounding airflow, turning this portion of the cooling airflow into hot air. Hot air, compared to cold air, has a significantly reduced ability to carry away heat. This results in the airflow entering the halogen lamp's heat dissipation channel being unable to effectively remove the heat generated by the halogen lamp during the cooling process, leading to poor heat dissipation for the halogen lamp.

[0005] Poor heat dissipation can cause a series of problems. On the one hand, halogen lamps operating in high-temperature environments for extended periods will accelerate the aging of their internal components, shorten their lifespan, and increase user costs and replacement frequency. On the other hand, excessively high temperatures may also affect the light stability and performance of the halogen lamp, preventing it from performing its auxiliary functions properly, thereby impacting the overall performance and user experience of the solar-powered hair dryer.

[0006] Therefore, to address the issue of poor heat dissipation caused by the lack of separation between the main air duct and the halogen lamp heat dissipation channel in existing solar-powered hair dryers, it is necessary to improve the internal structure of the hair dryer to enhance the heat dissipation efficiency of the halogen lamp and ensure the performance and stability of the solar-powered hair dryer. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a solar-powered hair dryer with dual air ducts.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] This utility model embodiment provides a photoelectric hair dryer with dual air ducts, including: a main body, an air outlet frame, a lamp cup, a mounting bracket, a heating frame, an end frame, a drive component, and a rear cover. The air outlet frame is installed at the front end of the main body, and the rear cover is installed at the rear end of the main body. The mounting bracket, the end frame, and the drive component are installed sequentially inside the main body from front to back, and the mounting bracket is connected to the end frame. The heating frame is sleeved on the outer periphery of the mounting bracket. The lamp cup is installed at the front end of the mounting bracket and has a light-emitting element. The drive component drives airflow to enter the main body along the rear cover. One airflow is heated by the heating frame and then blown out along the outer periphery of the mounting bracket and the air outlet frame, while the other airflow enters the interior of the mounting bracket along the end frame and is blown out.

[0010] In one specific embodiment, the lamp cup has a cup cavity, the light-emitting element is installed in the cup cavity, the rear end of the lamp cup is also provided with a lamp holder, and the lamp cup and the lamp holder form an air inlet groove; part of the airflow entering the interior of the mounting bracket enters the cup cavity along the air inlet groove and returns to the interior of the mounting bracket along the gap between the lamp cup and the mounting bracket, and merges with another part of the airflow and blows out along the air outlet frame.

[0011] In one specific embodiment, the mounting bracket has a mounting cavity at its front end and a sleeve at its rear end that communicates with the mounting cavity. The lamp cup is mounted in the mounting cavity, the heating frame is sleeved on the outside of the sleeve, and the sleeve communicates with the end frame.

[0012] In one specific embodiment, the end frame has a hollow structure and is provided with a connecting pipe, which is connected to the sleeve.

[0013] In one specific embodiment, a heat dissipation plate is also provided on the side of the end bracket away from the sleeve.

[0014] In one specific embodiment, the rear end of the lamp holder is connected to a lamp plate, the light-emitting element is connected to the lamp holder, and the front end of the light-emitting element extends into the cup cavity, while the rear end guide pin extends out of the lamp holder and is connected to the lamp plate.

[0015] In one specific embodiment, the rear end of the air outlet frame is sleeved onto the front end of the mounting bracket to form a sealed structure.

[0016] In one specific embodiment, a lens is provided at the front end of the cup cavity, and the light generated by the light-emitting element passes through the lens and is emitted.

[0017] In one specific embodiment, the main body is further provided with a mica tube on the outer periphery of the mounting bracket.

[0018] In one specific embodiment, a filter screen is also provided between the drive component and the rear cover.

[0019] The advantages of this utility model's dual-airflow light-powered hair dryer compared to existing technologies are as follows: By setting up a dual-airflow structure, the heating airflow and the cooling airflow are effectively separated; one airflow is heated by the heating frame and then blown out along the outer periphery of the mounting bracket and the air outlet frame to achieve the drying function; the other airflow enters the interior of the mounting bracket along the end frame and is blown out, specifically for cooling the lamp cup and its installed light-emitting components. This independent airflow design avoids interference between the heating airflow and the cooling airflow, ensuring that the airflow used for cooling always maintains a lower temperature, which can more effectively remove the heat generated by the light-emitting components, improve the heat dissipation efficiency, and thus extend the service life of the light-emitting components.

[0032] See Figures 1 to 3 The specific embodiment shown in this utility model discloses a photoelectric hair dryer with dual air ducts, including: a main body 10, an air outlet frame 20, a lamp cup 30, a mounting bracket 40, a heating frame 50, an end bracket 60, a driving component 70, and a rear cover 80. The air outlet frame 20 is installed at the front end of the main body 10, and the rear cover 80 is installed at the rear end of the main body 10. The mounting bracket 40, the end bracket 60, and the driving component 70 are sequentially installed inside the main body 10 from front to back. The end frame 60 is connected to the heating frame 50, which is sleeved on the outer periphery of the mounting bracket 40. The lamp cup 30 is installed at the front end of the mounting bracket 40, and the lamp cup 30 is equipped with a light-emitting element 90. The driving component 70 drives the airflow to enter the main body 10 along the rear cover 80. One airflow is heated by the heating frame 50 and then blown out along the outer periphery of the mounting bracket 40 and the air outlet frame 20. The other airflow enters the interior of the mounting bracket 40 along the end frame 60 and is blown out.

[0033] Specifically, the air outlet bracket 20 is securely installed at the front end of the main body 10. As the outlet for hot air, the air outlet bracket 20 is designed to ensure smooth airflow. Next, the rear cover 80 is installed at the rear end of the main body 10. The rear cover 80 typically has an air inlet so that the drive unit 70 can smoothly draw external air into the main body 10. Following a front-to-back sequence, the mounting bracket 40, end bracket 60, and drive unit 70 are sequentially installed inside the main body 10. Good connectivity must be ensured between the mounting bracket 40 and the end bracket 60, for example, through a specific interface or channel design, allowing smooth airflow between them. The heating element 50 is fitted around the outer periphery of the mounting bracket 40, ensuring a tight fit to the mounting bracket 40 to effectively transfer heat to the passing airflow. Subsequently, the lamp holder 30, which houses the light-emitting element 90, is installed at the front end of the mounting bracket 40. The position of the lamp holder 30 must ensure that the light-emitting element 90 functions properly and does not obstruct airflow.

[0034] When the hair dryer is turned on, the drive unit 70, consisting of a motor and an impeller, operates to rotate the impeller, creating a negative pressure inside the main body 10. This forces outside air into the main body 10 through the air inlet on the rear cover 80. The airflow entering the main body 10 is split by the drive unit 70. One airflow flows to the heating element 50, which generates a significant amount of heat. This airflow is heated as it passes through the heating element 50, forming hot air. The heated hot air flows along the outer periphery of the mounting bracket 40 and is eventually blown out through the outlet bracket 20 to dry hair or other objects. The other airflow enters the mounting bracket 40 along the end bracket 60. This airflow is unaffected by the heating element 50 and maintains a relatively low temperature. It blows directly onto the lamp cup 30 and its mounted light-emitting element 90, carrying away the heat generated by the light-emitting element 90 during operation, thus dissipating heat and ensuring that the light-emitting element 90 operates stably at a suitable temperature.

[0035] In other words, by setting up a dual-airflow structure, the heating airflow and the cooling airflow are effectively separated. One airflow is heated by the heating frame 50 and then blown out along the outer periphery of the mounting bracket 40 and the air outlet frame 20 to achieve the drying function. The other airflow enters the interior of the mounting bracket 40 along the end frame 60 and is blown out, specifically for cooling the lamp cup 30 and its installed light-emitting component 90. This independent airflow design avoids interference between the heating airflow and the cooling airflow, ensuring that the airflow used for cooling always maintains a lower temperature. This allows for more effective removal of the heat generated by the light-emitting component 90, improving heat dissipation efficiency and extending the service life of the light-emitting component 90. In addition, by effectively solving the heat dissipation problem, the accelerated aging of the light-emitting component 90 due to long-term exposure to high temperatures is avoided, ensuring the light stability and performance of the light-emitting component 90. This allows the photoelectric hair dryer to stably perform its auxiliary functions, such as scalp care and promoting blood circulation, while providing the drying function, thus improving the overall performance and reliability of the product.

[0036] Among them, see Figure 2 As shown, the thick arrow represents the flow path of one airflow after being heated by the heat source, which then blows out along the mounting bracket 40 and the outlet bracket 20; the thin arrow represents the flow path of another airflow that enters the interior of the mounting bracket 40 along the end bracket 60 and is then blown out. For ease of understanding, the flow path of the thick arrow is referred to as the main airflow, and the flow path of the thin arrow is referred to as the secondary airflow.

[0037] In one embodiment, the lamp cup 30 is provided with a cup cavity 31, the cup cavity 31 is equipped with the light-emitting element 90, the rear end of the lamp cup 30 is also provided with a lamp holder 100, and the lamp cup 30 and the lamp holder 100 form an air inlet groove; part of the airflow entering the interior of the mounting bracket 40 enters the cup cavity 31 along the air inlet groove and returns to the interior of the mounting bracket 40 along the gap between the lamp cup 30 and the mounting bracket 40, and merges with another part of the airflow and blows out along the air outlet frame 20.

[0038] Specifically, a portion of the secondary airflow enters the cup cavity 31 along the air inlet groove to dissipate heat from the light-emitting element 90. The dissipated airflow returns to the interior of the mounting bracket 40 along the gap between the lamp cup 30 and the mounting bracket 40, and the other portion of the secondary airflow (dissipating heat from the lamp cup 30) is blown out along the air outlet bracket 20.

[0039] More specifically, after the secondary airflow enters the mounting bracket 40, a portion of the airflow enters the cup cavity 31 of the lamp cup 30 along the air inlet slot. This portion of the airflow directly contacts the light-emitting element 90, carrying away the heat generated by the light-emitting element 90 during operation, thus achieving heat dissipation for the light-emitting element 90. The cooled airflow temperature rises, and then it returns to the mounting bracket 40 along the gap between the lamp cup 30 and the mounting bracket 40. The cooled airflow returning to the mounting bracket 40 merges with another portion of the secondary airflow that did not enter the air inlet slot. After these two portions of airflow merge, they continue to flow along the interior of the mounting bracket 40, and finally are blown out through the air outlet frame 20, completing the entire airflow circulation process.

[0040] In other words, a portion of the secondary airflow specifically enters the cup cavity 31 along the air inlet slot to directly dissipate heat from the light-emitting element 90. This targeted heat dissipation method can more effectively remove the heat generated by the light-emitting element 90, greatly improving heat dissipation efficiency. Compared with traditional heat dissipation methods, it can reduce the operating temperature of the light-emitting element 90 more quickly, preventing performance degradation or damage due to overheating. The dissipated airflow returns to the interior of the mounting bracket 40 along the gap between the lamp cup 30 and the mounting bracket 40, and merges with another portion of the secondary airflow before being blown out, forming a circulating heat dissipation system. This circulating heat dissipation method allows the airflow to be fully utilized, continuously removing the heat generated by the light-emitting element 90, further enhancing the heat dissipation effect and ensuring that the light-emitting element 90 can operate stably in a suitable temperature environment.

[0041] In one embodiment, the mounting bracket 40 has a mounting cavity 41 at its front end and a sleeve 42 at its rear end that is connected to the mounting cavity 41. The lamp cup 30 is mounted in the mounting cavity 41, the heating frame 50 is sleeved on the outside of the sleeve 42, and the sleeve 42 is connected to the end frame 60.

[0042] Specifically, the mounting bracket 40 is designed with a two-part structure; the front part has a mounting cavity 41 for fixing and supporting the lamp cup 30; the rear part has a sleeve 42 that communicates with the interior of the mounting cavity 41 to ensure smooth passage of the secondary airflow. The lamp cup 30 is precisely installed in the mounting cavity 41 at the front end of the mounting bracket 40. The lamp cup 30 has a cup cavity 31 inside, and the light-emitting element 90 is installed in the cup cavity 31. The heating frame 50 is designed as a ring structure, fitted outside the sleeve 42 at the rear end of the mounting bracket 40. When the main airflow passes through, it can fully contact the heating frame 50 and be heated to a suitable temperature. In addition, the drive unit 70 operates to draw in the airflow, which is then divided into a main airflow and a secondary airflow within the main body 10. The main airflow is heated by the heating frame 50 to form hot air, which is then blown out along the outside of the mounting bracket 40 and the air outlet frame 20 to provide hot air to the user. Simultaneously, the secondary airflow sequentially enters the end frame 60 and the mounting bracket 40 and exits, effectively cooling the light-emitting component 90 and improving heat dissipation. Furthermore, through the above design, the main airflow and the secondary airflow are separated in their flow paths. The main airflow flows along the outer side of the mounting bracket 40, while the secondary airflow flows along the mounting cavity 41 and the cup cavity 31. This design not only ensures smooth airflow but also improves heat dissipation efficiency and prevents overheating.

[0043] In one embodiment, the end frame 60 has a hollow structure and is provided with a connecting pipe 61, which is connected to the sleeve 42.

[0044] Specifically, the main airflow passes through the hollow structure to reach the area where the heating frame 50 is located, and the secondary airflow passes through the connecting pipe 61 and the sleeve 42 in sequence to reach the mounting cavity 41.

[0045] In other words, the perforated structure of the end cap 60 allows the main airflow to pass through the perforated area and directly reach the area where the heating element 50 is located, while the secondary airflow reaches the mounting cavity 41 through the connecting pipe 61 and the sleeve 42. This clear airflow distribution method ensures that different functional areas receive appropriate airflow supply, meeting the different needs of the hair dryer for drying and auxiliary functions (such as heat dissipation of the light-emitting component 90). Reasonable airflow distribution avoids airflow chaos and waste, improving airflow utilization efficiency. The main airflow can fully contact the heating element 50 to achieve efficient heating for quickly drying hair; the secondary airflow can precisely dissipate heat from components such as the lamp cup 30, ensuring their normal operation. Furthermore, the secondary airflow passes sequentially through the connecting pipe 61 and the sleeve 42 to reach the mounting cavity 41, directly dissipating heat from components such as the lamp cup 30 within the mounting cavity 41. This targeted heat dissipation method can more effectively remove the heat generated by the components, reducing their operating temperature and extending their service life. In addition, since the connecting pipe 61 and the sleeve 42 provide a dedicated channel for the secondary airflow, the flow resistance of the airflow inside the blower is reduced, allowing the secondary airflow to reach the heat dissipation area more quickly and improving the heat dissipation efficiency.

[0046] In one embodiment, the end bracket 60 is further provided with a heat sink 110 on the side away from the sleeve 42.

[0047] Specifically, the heat sink 110 is made of a material with good thermal conductivity, such as aluminum alloy or copper alloy. Aluminum alloy is lightweight, relatively inexpensive, and has good thermal conductivity, making it suitable for most hair dryer products; copper alloy has even better thermal conductivity, but it is more expensive and heavier, and the choice can be made based on product positioning and heat dissipation requirements. Because the heat sink 110 is made of a material with good thermal conductivity, it can quickly conduct heat from the end frame 60 and nearby components to itself, and then dissipate it into the air. Compared to the case without the heat sink 110, the heat transfer speed is significantly faster, and heat can be removed more quickly, preventing components from experiencing performance degradation or damage due to overheating.

[0048] In one embodiment, the lamp holder 100 is connected to a lamp plate 120 at its rear end, the light-emitting element 90 is connected to the lamp holder 100, and the front end of the light-emitting element 90 extends into the cup cavity 31, while the guide pin at its rear end extends out of the lamp holder 100 and is connected to the lamp plate 120.

[0049] Specifically, the lamp cup 30 is a container-like structure with an opening. Its front end is typically used for light transmission, while its rear end is used for connecting other components. The rear end of the lamp cup 30 is connected to the lamp holder 100. This connection can be a direct threaded connection, a snap-fit ​​connection, or other forms of fixing, ensuring that the lamp holder 100 is securely mounted on the lamp cup 30. The rear end of the lamp holder 100 is further connected to the lamp board 120, which is typically a circuit board with circuits and connection points corresponding to the light-emitting element 90. The connection between the lamp board 120 and the lamp holder 100 can be achieved through screws, snap-fits, welding, or other fixing methods, ensuring that the lamp board 120 can stably support the light-emitting element 90 and provide electrical connection. The light-emitting element 90 is connected to the lamp holder 100. The front end of the light-emitting element 90 extends into the cup cavity 31 of the lamp cup 30 to emit light, which is transmitted through the front end of the lamp cup 30. The rear end of the light-emitting element 90 usually has guide pins (or leads). These guide pins extend from the lamp holder 100 and connect to corresponding circuit connection points on the lamp board 120. The connection between the guide pins and the lamp board 120 can be achieved by soldering, plugging, or other electrical connection methods to ensure that the light-emitting element 90 can work properly.

[0050] More specifically, by sequentially connecting the lamp holder 100 and the lamp plate 120 to the rear end of the lamp cup 30, the entire lamp fixture has a more compact structure, reducing space occupation. This structure makes the installation and disassembly of the light-emitting element 90 more convenient, facilitating maintenance and replacement. In addition, the guide pins of the light-emitting element 90 are electrically connected to the circuit connection points on the lamp plate 120 through a stable connection method (such as soldering), ensuring the electrical performance and stability of the lamp fixture.

[0051] Preferably, the light-emitting element 90 is a halogen lamp. Halogen lamps, with their highly efficient light-emitting mechanism, can inject halogen gases such as iodine or bromine into the bulb, forming a stable tungsten filament regeneration cycle through a chemical reaction, thereby significantly enhancing the bulb's durability and brightness. Furthermore, due to the halogen cycle, halogen lamps can prevent premature tungsten filament breakage, thus extending the bulb's lifespan.

[0052] In one embodiment, the rear end of the air outlet frame 20 is sleeved on the front end of the mounting bracket 40 to form a sealed structure.

[0053] Specifically, the rear end of the air outlet frame 20 is fitted onto the front end of the mounting bracket 40 to form a sealed structure, effectively preventing airflow leakage at the connection point. During the operation of the hair dryer, the airflow generated by the drive component 70 flows along the designed path, preventing airflow loss due to leakage at the connection point, ensuring full utilization of airflow, and improving the drying efficiency of the hair dryer. Furthermore, the sealed structure helps maintain stable airflow pressure inside the air outlet frame 20. Stable airflow pressure allows the airflow to be blown out more evenly from the outlet area, improving the consistency of the drying effect and avoiding uneven drying caused by airflow pressure fluctuations. Additionally, the sealed structure allows the airflow to flow along a predetermined path, more effectively dissipating heat from the heating components inside the hair dryer. For example, after being heated by the heating element 50, the airflow can smoothly pass through the air outlet frame 20, carrying away the heat generated by the heating element 50. The sealed structure prevents airflow turbulence at the connection point, ensuring smooth flow of cooling airflow and improving heat dissipation efficiency.

[0054] In one embodiment, a lens 130 is provided at the front end of the cup cavity 31, and the light generated by the light-emitting element 90 passes through the lens 130 and is emitted.

[0055] Specifically, the design of the lens 130 allows the light generated by the light-emitting element 90 to be focused or directionally adjusted before being emitted. This means that the light no longer scatters randomly but propagates in a specific direction or angle. This focusing and directional control helps improve the efficiency of light utilization. Furthermore, the lens 130 acts as a barrier between the light-emitting element 90 and the external environment, effectively preventing dust, moisture, and other impurities from entering the cup cavity 31, thus protecting the light-emitting element 90 from damage. This protection not only extends the lifespan of the light-emitting element 90 but also ensures the stability and reliability of the product. The lens 130 also has the characteristic of blocking strong light without blocking heat, to avoid eye injury during use. The surface coating of the lens 130 is used to block strong light and dissipate the heat generated by the halogen lamp.

[0056] In one embodiment, an iron ring is provided at the front end of the air outlet frame 20 for configuring different air nozzles.

[0057] In one embodiment, the main body 10 is further provided with a mica tube 140 on the outer periphery of the mounting bracket 40, the front end of the mica tube 140 abutting against the air outlet frame 20 and the rear end abutting against the end frame 60.

[0058] Specifically, the mica tube 140 has excellent heat insulation properties, effectively preventing heat from being transferred to the outside of the hair dryer body 10. When the hair dryer is operating, components such as the heating element 50 generate a large amount of heat. The mica tube 140 acts as a barrier, isolating this heat inside the hair dryer and preventing direct heat transfer to the outside of the body 10, thereby reducing the external temperature of the body 10. Furthermore, through the heat insulation effect of the mica tube 140, the external temperature of the hair dryer body 10 can be significantly reduced.

[0059] In one embodiment, the heating frame 50 is not connected to the mounting bracket 40, but is connected to the mica tube 140 to adapt to different application scenarios.

[0060] In one embodiment, a heat insulation cylinder 150 is also provided on the outer periphery of the mica cylinder 140.

[0061] Specifically, the addition of the heat insulation cylinder 150 around the mica cylinder 140 creates an additional layer of heat insulation, forming a multi-layered insulation structure. During heat transfer, the material passes sequentially through the mica cylinder 140 and the heat insulation cylinder 150. Each layer of insulation blocks and absorbs heat, significantly reducing the efficiency of heat transfer to the exterior of the hair dryer body 10, thus dramatically enhancing the overall insulation effect. Through this dual insulation, the exterior temperature of the hair dryer body 10 is reduced even more significantly. Users will not experience discomfort due to excessively high casing temperatures even during prolonged use, further improving safety and comfort.

[0062] In one embodiment, a filter screen 160 is further provided between the drive member 70 and the rear cover 80.

[0063] Specifically, the air filter 160 effectively filters dust, hair, fibers, and other impurities from the air. During the operation of the hair dryer, the drive unit 70 needs to draw in a large amount of air to cool itself and generate airflow. Without the filtration of the air filter 160, these impurities would enter the drive unit 70 with the air, adhering to components such as the motor windings and impeller, leading to problems such as poor motor heat dissipation and slow fan rotation, and may even cause short circuits or damage to the motor. The air filter 160 significantly reduces the possibility of impurities entering the drive unit 70, extending its service life. In addition, the mesh structure of the air filter 160 allows for a more even distribution of air entering the drive unit 70. Even airflow improves the working efficiency of the drive unit 70 and reduces vibration and noise caused by uneven airflow. For example, when air passes through the mesh of the air filter 160, it is dispersed into multiple fine airflow jets. These airflow jets, after entering the drive unit 70, can make more even contact with the motor and fan, improving heat dissipation and airflow generation.

[0064] In one embodiment, the handle portion of the main body 10 is also equipped with a control board 170, and the drive unit 70, the heating frame 50 and the lamp board 120 are all electrically connected to the control board 170 to achieve normal operation.

[0065] The other specific structures of the main body 10 adopt existing publicly available technologies and will not be elaborated on here.

[0066] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
