Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, and more specifically, to a high-speed hair dryer with an air guide component. Background Technology

[0002] High-speed hair dryers are widely popular in the market due to their high airflow and rapid hair drying capabilities. The air guide, a crucial component of high-speed hair dryers, guides and regulates the airflow to meet diverse usage needs.

[0003] Existing high-speed hair dryers generally suffer from problems such as turbulent airflow and insufficient air pressure. Traditional air guide structures are mostly straight grids or simple curved surfaces, which can easily lead to large airflow turbulence losses, uneven air outlet temperature distribution, and obvious duct noise.

[0004] Therefore, we made improvements and proposed a high-speed hair dryer with an air guide. Utility Model Content

[0005] The purpose of this utility model is to provide a high-speed hair dryer with an air guide component.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A high-speed hair dryer with an air guide includes a hair dryer housing; a handle is rotatably fitted to the lower part of the hair dryer housing, and a rotating shaft is provided between the handle and the hair dryer housing; the hair dryer housing is provided with a heating chamber, an air guide chamber and an air inlet chamber in sequence from the front air outlet to the rear air inlet; an air guide assembly is provided inside the air guide chamber.

[0011] As a preferred embodiment of the high-speed blower with air guide provided by this utility model, the air guide assembly includes an annular frame disposed inside the air guide chamber, and a plurality of air guide plates are arranged in a circumferential array on the outer wall of the annular frame.

[0012] In a preferred embodiment of the high-speed blower with air guide provided by this utility model, the outer sides of the plurality of air guide plates are installed on the inner wall of the air guide chamber, and a main air duct is formed between two adjacent air guide plates and the inner wall of the air guide chamber.

[0013] As a preferred embodiment of the high-speed blower with air guide provided by this utility model, the inner wall of the annular frame is equipped with an Archimedes spiral air guide vane. The height of the Archimedes spiral air guide vane is gradually designed, with a wider front end and a narrower rear end. The gaps between the Archimedes spiral air guide vanes form a secondary air duct to achieve airflow stratification and acceleration. The windward surface of the Archimedes spiral air guide vane is provided with hemispherical protrusions to break the boundary layer airflow.

[0014] As a preferred embodiment of the high-speed hair dryer with air guide provided by this utility model, the Archimedes spiral air guide is provided with a tube that rotates with the drive shaft at the center of the annular frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model provides a high-speed hair dryer with an air guide component, comprising: a hair dryer housing; a handle rotatably fitted to the lower part of the hair dryer housing, with a rotating shaft between the handle and the hair dryer housing; the hair dryer housing having a heating chamber, an air guide chamber, and an air inlet chamber arranged sequentially from the front air outlet to the rear air inlet; and an air guide assembly disposed within the air guide chamber. Airflow stratification is achieved through the main and secondary air ducts of the air guide assembly. The unique spiral shape and gradually varying height design of the Archimedes spiral air guide vane guides the airflow to flow orderly along a specific trajectory, effectively reducing mutual interference and turbulence between airflows, and improving the stability and orderliness of the airflow. The gradually contracting secondary air duct formed by the gradually varying height of the Archimedes spiral air guide vane continuously accelerates the airflow during its flow, thereby increasing wind pressure. Compared to traditional structures, it can deliver air at a higher wind speed, accelerating hair drying and meeting users' needs for quick styling and hair drying. Attached Figure Description

[0031] Please refer to Figure 1-5 A high-speed hair dryer with an air guide includes: a hair dryer housing 1; a handle 2 rotatably fitted to the lower part of the hair dryer housing 1, and a rotating shaft 3 disposed between the handle 2 and the hair dryer housing 1; the hair dryer housing 1 has a heating chamber 4, an air guide chamber 5, and an air inlet chamber 6 arranged sequentially from the front air outlet to the rear air inlet; an air guide assembly 7 is disposed inside the air guide chamber 5. When the high-speed hair dryer is started, the motor 11 starts to run, driving the transmission shaft 12 to rotate, which in turn drives the fan blades 13 inside the air inlet chamber 6 to rotate at high speed. The rotation of the fan blades 13 generates suction, and outside air enters the air inlet chamber 6 from the air inlet at the rear end of the hair dryer housing 1 after being filtered by the shielding mesh 14.

[0032] Please refer to Figure 2 and Figure 3The heating chamber 4 is equipped with multiple air delivery plates 8 arranged in a circular array on the inner wall of the heating chamber 4. Spiral heating wires 9 are wound around the air delivery plates 8. A fixed cylinder 10 is installed on the side of the air delivery plates 8 near the air guide chamber 5. A motor 11 is installed on the inner wall of the fixed cylinder 10. A drive shaft 12 is installed on the output shaft of the motor 11. One end of the drive shaft 12, which extends laterally through the air guide chamber 5 to the air inlet chamber 6, is equipped with a fan blade 13. The fan blade 13 is located inside the air inlet chamber 6. A baffle mesh 14 is installed at the rear air inlet of the blower housing 1. The airflow, guided and accelerated by the air guide assembly 7, enters the heating chamber 4. The spiral heating wires 9 are wound around the circumferentially arrayed air delivery plates 8 inside the heating chamber 4. When the airflow passes through the gaps between the air delivery plates 8, it comes into full contact with the heating wires 9 and is heated evenly. The heated airflow continues to flow forward, passing through the channel formed by the fixed cylinder 10 and the air guide 707, and finally blown out from the air outlet at the front end of the blower housing 1.

[0033] Please refer to Figure 3-5The air guiding assembly 7 includes an annular frame 701 disposed inside the air guiding chamber 5. Multiple air guiding plates 702 are arranged in a circumferential array on the outer wall of the annular frame 701. The outer sides of the multiple air guiding plates 702 are mounted on the inner wall of the air guiding chamber 5. A main air duct 703 is formed between two adjacent air guiding plates 702 and the inner wall of the air guiding chamber 5. Archimedean spiral-shaped air guiding vanes 704 are installed on the inner wall of the annular frame 701. The height of the Archimedean spiral-shaped air guiding vanes 704 is gradually varied, being wider at the front and narrower at the rear. The gaps between the Archimedean spiral-shaped air guiding vanes 704 form secondary airflow. The Archimedes spiral guide vane 704, with its hemispherical protrusions 705 on its windward side, is used to break the boundary layer airflow. At the center of the annular frame 701, a tube 706, rotatably engaging with the drive shaft 12, is installed. Facing the air outlet at the front of the blower housing 1, the tube 706 is fitted with a guide shroud 707 that closes with the fixed cylinder 10. The guide shroud 707 is trumpet-shaped. After air enters the air inlet chamber 6, it is guided in an orderly manner by the air guide assembly 7. In the air guide assembly 7, the guide plates 702 arranged circumferentially on the outer wall of the annular frame 701 and the inner wall of the air chamber 5 form the main air duct 703. Simultaneously, the gaps between the Archimedes spiral guide vanes 704 on the inner wall of the annular frame 701 form the secondary air duct 708, achieving stratified airflow introduction. Air enters the main air duct 703 and the secondary air duct 708 respectively, flowing along the guide paths of the air guide plate 702 and the Archimedes spiral-shaped air guide vane 704. Because the height of the Archimedes spiral-shaped air guide vane 704 is gradually changing (wider at the front and narrower at the end), the channel gradually narrows as the air flows along the secondary air duct 708. According to fluid dynamics principles, the airflow is gradually accelerated. Simultaneously, the hemispherical protrusions 705 on the windward side of the Archimedes spiral-shaped air guide vane 704 effectively break the boundary layer airflow, reducing frictional resistance between the airflow and the air guide vane, allowing for smoother airflow.

[0034] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
