Description

Technical Field

[0001] The invention belongs to the technical field of hair dryer manufacturing, and in particular relates to a double-air-duct high-speed hair dryer. Background Art

[0002] Nowadays, with the continuous development of science and technology, hair dryers are used more and more in people's lives.

[0003] A hair dryer is a tool for drying and styling hair, which is composed of a set of electric heating wires and a small fan wheel. When powered on, the electric heating wires will generate heat, and the wind blown out by the fan wheel will become hot air after passing through the electric heating wires. If only the small fan wheel rotates and the electric heating wires are not hot, the wind blown out is cold air instead of hot air. The existing hair dryers of this type generally have a relatively simple structure.

[0004] In order to increase the hair drying speed faster, some hair dryers nowadays use the principles of fluid mechanics to increase the size of the air outlet. The middle of the hair dryer is hollowed out, and a circle of air outlets is wrapped around the outer circle of the hollow part. The air flow from the air outlet drives the air flow in the hollow part, so that the blown wind will be stronger. This design increases the wind speed, but it also brings a problem. When the motor speed is constant, the increase in wind speed and air volume is limited, which cannot meet the needs of consumers with thick hair to dry their hair quickly. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a dual-duct high-speed hair dryer, which can increase the wind speed and the amount of wind volume while keeping a motor speed constant, thereby meeting the needs of consumers with thick hair for quick hair drying.

[0006] In order to solve the above technical problems, the present invention is solved through the following technical solutions: a dual-air-duct high-speed hair dryer, comprising a hair dryer handle and a hair dryer hair dryer barrel, the hair dryer barrel is fixedly provided with the hair dryer barrel at one end of the handle, a hollow area is provided on the hair dryer barrel, a first air inlet is provided at the lower part of the hair dryer handle, a first cavity is provided in the hair dryer handle, a first motor fan assembly and a first button assembly are fixedly provided on the first cavity, the first button assembly comprises a sliding button assembly, the sliding button assembly controls the first motor fan assembly, a second cavity is provided in the hair dryer barrel, a first air outlet is provided at one end of the second cavity, the other end of the second cavity is closed, the first cavity and the second cavity are communicated, the inner wall of the hollow area forms a second air outlet at the first air outlet end and a second air inlet at the other end, the second air outlet A fan wheel is provided between the first air inlet and the second air inlet through a bearing for rotation connection, the first air inlet, the first air outlet, the first cavity and the second cavity form a first air duct, the second air inlet, the hollow area and the second air outlet form a second air duct, when the hair dryer is needed, the sliding button assembly is pushed to control the opening and size of the first motor fan assembly, because the first air outlet utilizes the airflow blown out by the first motor fan assembly to drive the air flow of the second air outlet, and the air flow in the hollow area drives the fan wheel, and driven by the air brought in by the second air inlet, the fan wheel brings out more wind, and at the same time, as the amount of wind brought out increases, the wind speed also increases, and the amount of increase in wind speed and air volume increases, so that the wind speed and the amount of increase in air volume can be increased while the motor speed is constant, so as to meet the needs of consumers with thick hair for quick hair drying.

[0007] In the above technical solution, preferably, the fan wheel is a second motor fan assembly, the connecting end of the second motor fan assembly is connected to a motor, and the hair dryer blower tube is fixedly provided with a second button assembly on the second air inlet side, and the second button assembly controls the second motor fan assembly. When the hair dryer needs to be used, the sliding button assembly is pushed to control the opening and size of the first motor fan assembly. When the required wind speed is about to be reached, the second button assembly is pressed to control the size of the second motor fan assembly, thereby increasing the wind speed in the second air duct. Because the size of the wind speed in the second air duct affects the wind speed in the first air duct slightly, the hair dryer can more conveniently adjust the size of the blown wind speed.

[0008] In the above technical solution, preferably, a heating rack is provided in the second cavity, and the heating rack is between the first air inlet and the first air outlet. The first button assembly includes a push button assembly, and the push button assembly controls the heating rack. This design increases the ability of the hair dryer to switch between cold air and hot air and the ability to adjust the temperature.

[0009] In the above technical solution, preferably, the size of the fan blades is similar to the size of the hollow area. This design increases the effect of the fan on the wind speed in the second air duct.

[0010] In the above technical solution, preferably, the first cavity is provided with an air inlet mesh plate at the lower end of the first motor fan assembly, and the hair dryer handle is divided into an upper shell and a lower shell, and the upper shell and the lower shell are fixed to each other. This design is more convenient when installing the first motor fan assembly and fixes the first motor fan assembly at the same time, while reducing the occurrence of damage to the first motor fan assembly caused by large objects blown in.

[0011] In the above technical solution, preferably, a connecting column is provided on the first button assembly, and the first cavity and the connecting column are fixed to each other by internal and external threads. This design can firmly fix the first button assembly.

[0012] In the above technical solution, preferably, the second button assembly is arranged on the second air inlet side of the hair dryer barrel. This design can more intuitively adjust the second motor fan assembly.

[0013] In the above technical solution, preferably, a first filter is fixedly provided on the first air inlet, and this design protects the components in the first air duct.

[0014] In the above technical solution, preferably, a second filter is fixedly provided on the second air inlet, and this design protects the components in the second air duct.

[0017] The present invention preferably provides a heating rack in the second cavity, and the heating rack is between the first air inlet and the first air outlet, and a button assembly is provided to control the heating rack. This design increases the ability of the hair dryer to switch between cold air and hot air and to adjust the temperature.

[0018] The present invention designs the size of the blades of the fan wheel to be similar to the size of the hollow area, and this design increases the influence of the fan wheel on the wind speed in the second air duct.

[0019] The present invention provides an air inlet mesh plate at the lower end of the first motor fan assembly, and the hair dryer handle is divided into an upper shell and a lower shell, which is more convenient when installing the first motor fan assembly and fixes the first motor fan assembly at the same time, and reduces the occurrence of damage to the first motor fan assembly caused by large objects blown in.

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figures 1 to 4, Embodiment 1, a dual-air-channel high-speed hair dryer comprises a hair dryer handle 1 and a hair dryer hair dryer barrel 2, a hair dryer hair dryer barrel 2 is fixedly provided at one end of the handle 1, a hollow area 3 is provided on the hair dryer hair dryer barrel 2, a first air inlet 4 is provided at the lower part of the hair dryer handle 1, a first cavity 5 is provided in the hair dryer handle 1, a first motor fan assembly 6 and a first button assembly 7 are fixedly provided on the first cavity 5, and the fixing method can be fixed by buckles and screws, the first button assembly 7 comprises a sliding button assembly 8, the sliding button assembly 8 controls the first motor fan assembly 6, controls the opening and size of the first motor fan assembly 6, a second cavity 9 is provided in the hair dryer hair dryer barrel 2, a first air outlet 10 is provided at one end of the second cavity 9, and the other end of the second cavity 9 is closed, the first cavity 5 and the second cavity 9 are communicated, the inner wall of the hollow area 3 forms a second air outlet 11 at the end of the first air outlet 10 and a second air inlet 12 at the other end, and the second air outlet 11 and the second air inlet 12 are communicated. A fan wheel 13 is provided through a bearing rotation connection. The fixing method can be that the fan is installed on the bearing through an axis. The first air inlet 4, the first air outlet 10, the first cavity 5 and the second cavity 9 form a first air duct 15, and the second air inlet 12, the hollow area 3 and the second air outlet 11 form a second air duct 14. When the hair dryer is needed, the sliding button assembly 8 is pushed to control the opening and size of the first motor fan assembly 6. Because the air flows into the first air inlet 4, the first air outlet 10 blows out the air, and the air flows on the second air outlet 11. The air flow in the hollow area 3 drives the fan wheel 13. Driven by the air brought in by the second air inlet 12, the rotation speed of the fan wheel 13 becomes faster, the fan wheel 13 brings out more wind, and the wind speed blown out of the second air outlet 11 becomes faster. The total amount blown out by the hair dryer becomes more and the total wind speed also becomes faster, which realizes that the wind speed and the amount of air volume can be increased under the condition of a constant motor speed, so as to meet the needs of consumers with thick hair to dry their hair quickly.

[0029] See also Figures 5 and 6 , Figures 5 and 6 Another embodiment of a hair dryer is shown. The difference between Example 2 and Example 1 is the different structural composition in the hollow area. The difference is that the fan wheel 13 is a second motor fan assembly 50, and the connecting end of the second motor fan assembly 50 is connected to the motor 16. The hair dryer barrel 2 is fixedly provided with a second button assembly 17 on the second air inlet 12 side. The second button assembly 17 controls the second motor fan assembly 50. When the hair dryer needs to be used, the sliding button assembly 8 is pushed to control the opening and size of the first motor fan assembly 6. When the required wind speed is about to be reached, the second button assembly 17 is pressed, and the size of the second motor fan assembly 50 is controlled by pressing more times, so as to increase the wind speed in the second air duct 14. Because the size of the wind speed in the second air duct 14 affects the wind speed in the first air duct 15 slightly, the hair dryer can more conveniently adjust the size of the blown wind speed.

[0030] In this embodiment, a heating rack 18 is provided in the second cavity 9, and the heating rack 18 is between the first air inlet 4 and the first air outlet 10. The first button assembly 7 includes a push button assembly 19, and the push button assembly 19 controls the heating rack 18. The temperature of the heating rack 18 can be set by pressing the push button assembly 19 a number of times, and the heating rack can be turned off by long pressing to increase the ability of the hair dryer to switch between cold air and hot air and the ability to adjust the temperature.

[0031] In this embodiment, the size of the blades of the fan wheel 13 is similar to the size of the hollow area 3 . This design increases the influence of the blades on the fan wheel 13 on the wind speed in the second air duct 14 .

[0032] In this embodiment, the first cavity 5 is provided with an air inlet mesh plate 20 at the lower end of the first motor fan assembly 6, and the hair dryer handle 1 is divided into an upper shell 21 and a lower shell 22. The upper shell 21 and the lower shell 22 are fixed to each other. The fixing method can be fixed by setting screw holes and screws, or by snap fastening. When installing the first motor fan assembly 6, this design can position and fix the first motor fan assembly 6 through the air inlet mesh plate 20, while reducing the occurrence of damage to the first motor fan assembly 6 caused by large objects blown in. Then the upper shell 21 and the lower shell 22 are fixed to each other, which is more convenient and fixes the first motor fan assembly 6 at the same time.

[0033] In this embodiment, a connecting column 23 is provided on the first button assembly 7 , and the first cavity 5 and the connecting column 23 are fixed to each other through internal and external threads. This design can firmly fix the first button assembly 7 .

[0034] In this embodiment, the second button assembly 17 is arranged on the side of the second air inlet 12 of the hair dryer barrel 2. This design allows the rotation speed of the second motor fan assembly 50 in the second air inlet 12 to be viewed, and the second button assembly 17 can be pressed to adjust the rotation speed of the second motor fan assembly 50, thereby adjusting the second motor fan assembly 50 more intuitively.

[0035] In this embodiment, a first filter screen 24 is fixedly disposed on the first air inlet 4 . This design protects the components in the first air duct 15 .
