Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, specifically to a hair dryer head with a heat-insulating annular cavity structure. Background Technology

[0002] The heat-insulating annular cavity structure of a hair dryer head involves designing a ring-shaped cavity space in a specific area of ​​the hair dryer head. This cavity is filled with a material with good heat insulation properties or employs a special heat insulation structure. Its main purpose is to effectively prevent the heat generated by the internal heating elements from being conducted to the outside during hair dryer operation, thereby reducing the surface temperature of the hair dryer head and avoiding the risk of burns from overheating. It also helps the internal electronic components operate normally in a relatively stable temperature environment, extending the lifespan of the hair dryer head and improving the overall user experience and safety.

[0003] However, existing hair dryers with heat-insulating ring structures still have some problems. Although the heat-insulating ring can provide some insulation, its insulation effect may gradually decrease under prolonged, high-power use. It may not be able to continuously and effectively maintain the surface of the hair dryer within a safe temperature range, and the heat accumulation inside may affect the airflow and heat dissipation efficiency inside the hair dryer, thus adversely affecting the performance and lifespan of the hair dryer.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a hair dryer with a heat-insulating annular cavity structure to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A hair dryer with a heat-insulating annular cavity structure includes a hair dryer housing, a heat insulation component 1 is disposed inside the hair dryer housing, and a heat insulation component 2 is disposed outside the hair dryer housing. The heat insulation component 1 includes a processing component 1 and a processing component 2, which are respectively disposed inside the hair dryer housing. The heat insulation component 2 includes a processing component 3, which is disposed on the outer wall of the hair dryer housing.

[0008] Furthermore, the processing component includes a bearing, which is located inside the blower housing. A guide cover is fixedly connected inside the bearing, and a support frame is located inside the guide cover. One end of the support frame is movably connected to the blower housing.

[0009] Furthermore, the support frame is equipped with processing blades, and heating wires are fixedly installed at equal intervals on the inner wall of the guide cover.

[0010] Furthermore, the second processing component includes a heat insulation layer 1 and a heat insulation layer 2, which are respectively disposed on the inner wall and outer wall of the guide cover, and both the heat insulation layer 1 and the heat insulation layer 2 are adapted to the guide cover.

[0011] Furthermore, the processing component three includes a conductive layer disposed on the outer wall of the blower housing, and the outer wall of the conductive layer is provided with multiple conveying ends and a heat insulation layer three.

[0012] Furthermore, heat dissipation holes are evenly spaced on the third heat insulation layer, and the conveying end is located inside the heat dissipation holes and is adapted to the heat dissipation holes.

[0013] The beneficial effects of this utility model are as follows: Through the cooperation of heat insulation component one and heat insulation component two, the heat insulation performance of the hair dryer head is effectively improved. Heat insulation layer one and heat insulation layer two in heat insulation component one, together with the guide cover, form a heat insulation ring cavity, which can effectively block the heat generated by the heating wire from being conducted to other parts inside the hair dryer shell, avoiding heat accumulation that affects the normal operation of internal components. At the same time, the conduction layer, conveying end and heat insulation layer three in heat insulation component two cooperate with each other to quickly conduct the heat inside the hair dryer shell to the outside and dissipate it, reducing the surface temperature of the hair dryer head, preventing users from being burned, extending the service life of the hair dryer head, and improving the user experience and safety.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] like Figures 1-5 As shown, a hair dryer head with a heat-insulating annular cavity structure according to an embodiment of the present utility model includes a hair dryer shell 1. The hair dryer shell 1 is made of heat-resistant plastic, which serves to protect the internal components and provide insulation. The hair dryer shell 1 is equipped with a motor, a fan, a switch and control device, a thermostat / overheat protector, a power cord and plug, and an air inlet filter. The hair dryer shell 1 is provided with a heat insulation component 1, which includes a processing component 2 and a processing component 3. The processing component 2 and the processing component 3 are respectively disposed inside the hair dryer shell 1.

[0028] The processing component 2 includes a bearing 5, which is located inside the blower housing 1. A guide cover 6 is fixedly connected inside the bearing 5. A support frame 7 is installed inside the guide cover 6. The support frame 7 is made of high-temperature resistant plastic material, which has good support performance and stability and can withstand the high temperature and airflow impact generated when the blower is working. One end of the support frame 7 is movably connected to the blower housing 1. Processing blades 8 are installed on the support frame 7. Heating wires 9 are fixedly installed at equal intervals on the inner wall of the guide cover 6. The heating wires 9 are electrically connected to the control device.

[0029] The second processing component 3 includes a first heat insulation layer 10 and a second heat insulation layer 11. The first heat insulation layer 10 and the second heat insulation layer 11 are respectively disposed on the inner wall and the outer wall of the guide cover 6, and both the first heat insulation layer 10 and the second heat insulation layer 11 are adapted to the guide cover 6.

[0030] The first heat insulation layer 10 is made of aerogel felt with a thickness of 5mm. It is tightly bonded to the inner wall of the guide cover 6 and fixed to the guide cover 6 with high-temperature resistant adhesive. It can effectively prevent the heat generated by the heating wire 9 from being transferred to the outer wall of the guide cover 6. The second heat insulation layer 11 is made of ceramic fiber board with a thickness of 8mm. It is also bonded to the outer wall of the guide cover 6 with high-temperature resistant adhesive. It further enhances the heat insulation effect and prevents heat from accumulating inside the hair dryer housing 1, which would affect the normal operation of other components. Both aerogel felt and ceramic fiber board are known high-efficiency heat insulation materials, and their performance indicators can meet the heat insulation requirements of the hair dryer.

[0031] Example 2:

[0032] like Figures 1-3 , Figure 6 , Figure 7 , Figure 8 As shown, according to an embodiment of the present utility model, a hair dryer head with a heat insulation ring cavity structure is provided on the outside of the hair dryer shell 1. The heat insulation component 2 includes a processing component 3 4, which is disposed on the outer wall of the hair dryer shell 1.

[0033] The processing component 3 4 includes a conductive layer 12, which is disposed on the outer wall of the blower housing 1. The outer wall of the conductive layer 12 is provided with multiple conveying ends 13 and a heat insulation layer 3 14. Heat dissipation holes 15 are evenly spaced on the heat insulation layer 3 14. The conveying ends 13 are disposed inside the heat dissipation holes 15 and are adapted to the heat dissipation holes 15. The heat insulation annular cavity structure is formed by the heat insulation layer 10, the heat insulation layer 2 11 and the guide cover 6. The heat insulation layer 3 14 is made of rubber.

[0034] The conductive layer 12 is made of aluminum alloy with a thickness of 3mm. It is connected to the outer wall of the hair dryer shell 1 by screws to ensure that the conductive layer 12 fits tightly with the hair dryer shell 1. It can effectively conduct the heat inside the hair dryer shell 1 to the outside. The screws are made of stainless steel, which has good corrosion resistance and strength, and can ensure that the conductive layer 12 is stably fixed during long-term use.

[0035] The heat dissipation holes 15 are circular with a diameter of 10mm and are distributed in a matrix on the heat insulation layer 3 14. The spacing between adjacent heat dissipation holes 15 is 15mm to ensure that heat can be dissipated evenly. The arrangement of the heat dissipation holes 15 can meet the heat dissipation requirements without affecting the overall structural strength of the heat insulation layer 3 14, ensuring its good heat insulation effect on the outer wall of the blower housing 1. The conveying end 13 is a cylindrical metal tube that matches the heat dissipation holes 15. One end is inserted into the heat dissipation hole 15 and fits tightly with the heat insulation layer 3 14. The other end is connected to the conductive layer 12 to form a complete heat dissipation channel, so that heat can be conducted through the conductive layer 12 and then dissipated to the external environment through the heat dissipation holes 15 and the conveying end 13. The material of the conveying end 13 is brass, which has good thermal conductivity and can accelerate the dissipation of heat.

[0036] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0037] In summary, with the help of the above-mentioned technical solution of this utility model, when the hair dryer is working, the heating wire 9 inside the hair dryer housing 1 is energized and generates heat to blow out hot air. At this time, the heat insulation layer 10 and the heat insulation layer 11 in the heat insulation component one, together with the guide cover 6, form a heat insulation ring cavity, which blocks the heat generated by the heating wire 9 from being conducted to other components inside the hair dryer housing 1, preventing heat accumulation from affecting the normal operation of internal components. The bearing 5 in the processing component one 2 is fixedly connected to the guide cover 6, and one end of the support frame 7 is movably connected to the hair dryer housing 1. The processing blades 8 on the support frame 7 help air flow. The heating wires 9, which are equidistantly arranged on the inner wall of the guide cover 6, are electrically connected to the control device. Together, they generate and effectively utilize hot air. In the processing component two 3, the heat insulation layer 10 is made of aerogel felt material and is tightly attached to the inner wall of the guide cover 6. The heat insulation layer 11 is made of ceramic fiber board material and is bonded to the outer wall of the guide cover 6. The two work together to further enhance the heat insulation effect and block heat transfer.

[0038] Meanwhile, the second heat insulation component plays a heat dissipation role on the outside of the hair dryer housing 1. The conductive layer 12 in the third processing component 4 is set on the outer wall of the hair dryer housing 1. The outer wall of the conductive layer 12 is provided with multiple conveying ends 13 and the third heat insulation layer 14. Heat dissipation holes 15 are opened at equal intervals on the third heat insulation layer 14. The conveying ends 13 are set inside the heat dissipation holes 15 and are adapted to them. The conductive layer 12 is made of aluminum alloy and is tightly attached to the outer wall of the hair dryer housing 1, which can effectively conduct the heat inside the hair dryer housing 1 to the outside. The heat dissipation holes 15 are distributed in a matrix to ensure that the heat is evenly distributed. The conveying end 13 is a cylindrical metal tube. One end is inserted into the heat dissipation hole 15 and tightly attached to the third heat insulation layer 14. The other end is connected to the conductive layer 12 to form a complete heat dissipation channel. After the heat is conducted through the conductive layer 12, it is dissipated into the external environment through the heat dissipation holes 15 and the conveying end 13, which reduces the surface temperature of the hair dryer head, prevents users from being burned, extends the service life of the hair dryer head, and improves the user experience and safety.
