Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, and in particular to a rapid heat dissipation device for a hair dryer. Background Technology

[0002] Hair dryers are common electrical appliances, often used for drying and conditioning hair. Most hair dryers contain a fan to guide airflow and a heating element to heat the air. Airflow is drawn into the dryer by the fan, heated by the heating element, and then blown out as hot air through the outlet. The heating element's function can be controlled by a control element, allowing users to easily turn it on or off as needed.

[0003] For example, Chinese Patent Publication No. CN212345676U discloses a high-heat-dissipation hair dryer, which is designed to address the technical problems of poor heating frame structure design in existing similar products, resulting in inconvenient assembly and production, and poor heat dissipation and heating effects. The hair dryer has an inner sleeve inside the blower housing, containing a heating frame and a circuit board assembly. A rear cover is provided at the rear of the inner sleeve and the blower housing. The key feature is that the heating frame includes a heating cylinder and heating elements. The heating elements are vertically and evenly distributed on the outer circumference of one end of the heating cylinder. The heating elements are mica sheets. The other end of the heating cylinder is inserted into or inserted into a circuit board that extends beyond the circuit board assembly via a column foot. A sealing ring is provided at one end of the cylinder where the circuit board connects to the heating cylinder. Electronic components are located on one side of the heating cylinder of the circuit board. The heating elements are L-shaped, with one end inserted into a slot block fixed to the heating cylinder, and the other bent end inserted into a slot fixed to the heating cylinder.

[0004] Current hair dryers use motors as the driving force, but when air is drawn in and pressurized, dust can easily clog the air intake, causing the hair dryer to malfunction. However, it is difficult to clean the dust clogging the air intake of existing hair dryers, which affects the normal use effect. Moreover, when the motor inside the hair dryer works for too long, it will overheat and require heat dissipation and cooling. However, the current heat dissipation method is static cooling, which results in excessively long cooling time and difficulty in quickly cooling the motor inside the hair dryer.

[0005] Therefore, it is necessary to provide a hair dryer with a rapid heat dissipation device to solve the above-mentioned technical problems. Utility Model Content

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Please see Figure 1-6 This utility model provides a hair dryer rapid heat dissipation device, including a housing 1, a handle 2 fixed to one side wall of the housing 1, a power cord 3 fixed to one side of the handle 2, multiple control switches 4 provided on one side of the handle 2, a bracket 5 fixed to the inner side wall of the housing 1, a motor 6 fixed to one side wall of the bracket 5, a heat dissipation component 7 provided on one side of the housing 1, a rotating shaft 8 fixed to one end of the output shaft of the motor 6, a fan blade 9 tightly sleeved on the outer surface of the rotating shaft 8, an air inlet groove 10 opened on one side of the housing 1, an installation ring 11 fixed to the inner side wall of the housing 1, a heating unit 12 fixed to one side wall of the installation ring 11, an air outlet groove 13 opened on one side wall of the housing 1, a nozzle 14 fixed inside the air outlet groove 13, and an air filter component 15 provided on one side of the air inlet groove 10.

[0028] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it is worth noting that the heat dissipation component 7 includes a groove 701 formed on the outer sidewall of the housing 1. The outer sidewall of the housing 1 has multiple circumferentially distributed through holes 702. A cover ring 703 is slidably connected inside the groove 701. A loading ring 704 is fixed on the inner sidewall of the housing 1. A plurality of circumferentially distributed mounting slots 705 are formed on one sidewall of the loading ring 704. A cooling fan 706 is fixed inside the mounting slot 705. The cooling fan 706 is located on one side of the motor 6. Through the setting of the heat dissipation component 7, the heat dissipation work of the motor 6 and the inside of the housing 1 can be completed in a short time. Not only is the cooling speed fast, but it can also cool down the motor 6 in time to achieve the purpose of protection. With the multiple cooling fans 706 generating wind at the same time to achieve air convection, the heat dissipation efficiency of the motor 6 and the inside of the housing 1 is good and the practicality is strong.

[0029] Further as Figure 1 , Figure 4 and Figure 6 As shown, it is worth noting that the cross-section of the cover ring 703 is arc-shaped, the cross-section of the loading ring 704 is arc-shaped, and multiple cooling fans 706 are arranged in a circular pattern around one side of the motor 6. Through the positioning of the cooling fans 706, the cooling of the motor 6 can be efficiently completed.

[0030] The working process of this solution is as follows: When this device is used, the motor 6 drives the rotating shaft 8 to rotate synchronously, which drives the fan blade 9 to rotate. This causes the airflow to enter the housing 1 through the air inlet slot 10, be pressurized, and then be input to the heating unit 12. After the air is heated, it is output from the air outlet slot 13. When the motor 6 is overheated, the cover ring 703 is pushed until the cover ring 703 releases the sealing state of the multiple through holes 702. The cooling fan 706 drives the wind to accelerate the airflow speed inside the housing 1 and around the motor 6, thereby quickly cooling the motor 6.

[0031] As can be seen from the above working process, the heat dissipation component 7 can complete the heat dissipation of the motor 6 and the interior of the housing 1 in a short time. It not only cools down quickly, but also cools down the motor 6 in time to achieve the purpose of protection. With the help of multiple cooling fans 706, air convection is achieved, which has good heat dissipation efficiency for the motor 6 and the interior of the housing 1. It is practical. With the air filter component 15, the air entering the housing 1 can be filtered multiple times. It is also easy to disassemble and clean. When cleaning is required, the metal filter screen can be manually removed by rotating the cover 1506 for cleaning and maintenance. Moreover, the installation method is simple and the connection stability is good, achieving the purpose of quick disassembly and efficient maintenance and cleaning.

[0032] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it is worth noting that the air filtration assembly 15 includes a filter plate 1501 fixed inside the air inlet groove 10, a magnetic ring a1502 fixed inside the air inlet groove 10, a metal filter ring 1503 magnetically connected to one side of the magnetic ring a1502, a connecting ring 1504 fixed to one side wall of the housing 1, a threaded groove 1505 opened on the outer side wall of the connecting ring 1504, and a cover 1506 threadedly connected to the outer surface of the connecting ring 1504. A plurality of equally spaced through grooves 1507 are opened on one side wall of the cover 1506. Through the setting of the air filtration assembly 15, not only can the air entering the housing 1 be filtered multiple times, but it is also convenient to disassemble and clean. When cleaning is required, the metal filter screen can be manually removed by rotating the cover 1506 for cleaning and maintenance. Moreover, the installation method is simple and the connection stability is good, achieving the purpose of quick disassembly and efficient maintenance and cleaning.

[0033] Further as Figure 3 , Figure 5 and Figure 6As shown, it is worth noting that the central axis of the filter plate 1501 and the central axis of the metal filter ring 1503 are collinear. The filter plate 1501 is located on one side of the fan blade 9. By setting the filter plate 1501 and the metal filter ring 1503 on the same axis, it can be ensured that the air intake and filtration are in a good and effective state.

[0034] Further as Figure 3 As shown, it is worth noting that a magnetic ring b is fixed on one side wall of the housing 1. The magnetic ring b is located on one side of the nozzle 14, and the nozzle 14 is located on one side of the heating unit 12. The setting of the magnetic ring b makes it convenient to install and replace nozzles of different shapes and functions, making the operation simpler and more convenient, and the structure is simpler and the cost is lower.

[0035] Further as Figure 3 , Figure 5 and Figure 6 As shown, it is worth noting that the central axis of the cover ring 703 is collinear with the central axis of the housing 1, and the cross-section of the housing 1 is circular. The shape of the housing 1 can improve the overall aesthetics of the device to a certain extent, and the surface is more rounded and smooth. In conjunction with the shape of the cover ring 703, it ensures that the movement of the cover ring 703 is relatively smooth and stable.

[0036] In summary: the positioning of the cooling fan 706 efficiently dissipates heat from the motor 6; the coaxial alignment of the filter plate 1501 and the metal filter ring 1503 ensures efficient and effective air intake and filtration; the magnetic ring b facilitates the installation and replacement of nozzles of different shapes and functions, making operation simpler and more convenient; the structure is simple and the cost is lower; and the shape of the housing 1 enhances the overall aesthetics of the device, making the surface smoother and more rounded. Combined with the shape of the cover ring 703, this ensures smooth and stable movement of the cover ring 703.

[0037] The motor 6, cooling fan 706 and heating unit 12 can all be purchased from the market. The motor 6 and cooling fan 706 are equipped with power supplies. These are mature technologies in the field and have been fully disclosed. Therefore, they will not be described again in the specification.
