[0030] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model discloses a hair dryer with adjustable airflow direction, including a main body 1 and a switching mechanism 2.

[0032] The main unit 1 is cylindrical. The side wall of the housing 11 of the main unit 1 is provided with a first air outlet 111 and a second air outlet 112, which are set at an angle α, where 0° < α ≤ 90°. The switching mechanism 2 includes a drive knob 21, a rotating shaft 22, a drive gear 23, and a moving plate 24. At least a portion of the drive knob 21 is located outside the housing 11. The rotating shaft 22 is rotatably disposed inside the housing 11 and connected to the drive knob 21. The drive gear 23 is located inside the housing 11 and is sleeved on the rotating shaft 22. The moving plate 24 is movably disposed inside the housing 11. The moving plate 24 can block either the first air outlet 111 or the second air outlet 112. The moving plate 24 is provided with a rack 25, which meshes with the drive gear 23.

[0033] The above technical solution enables the hair dryer to change the airflow direction without the need for nozzle accessories, and the main body 1 is a straight cylinder shape, making it more convenient to store.

[0034] In practical applications, the main body 1 includes a housing 11, a fan motor 12, a control circuit board 13, and a heating element 14. A cavity 114 is formed within the housing 11, selectively communicating with either a first air outlet 111 or a second air outlet 112. An air inlet 115 communicating with the cavity 114 is provided on the side wall of the housing 11. The fan motor 12, control circuit board 13, and heating element 14 are all disposed within the cavity 114, and both the fan motor 12 and the heating element 14 are electrically connected to the control circuit board 13.

[0035] When air needs to be discharged from the first air outlet 111, firstly, rotate the drive knob 21. The drive knob 21 drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the drive gear 23 to rotate. The drive gear 23 drives the moving plate 24 to move through the rack 25, so that the moving plate 24 blocks the second air outlet 112. Then, the fan motor 12 can be started alone or simultaneously with the heating element 14 by the control button on the side wall of the housing 11 connected to the control circuit board 13, so that the outside air flows through the air inlet 111. Air enters cavity 114 through air inlet 115 and is then blown out through first air outlet 111. If air needs to exit through second air outlet 112, the drive knob 21 is rotated in the opposite direction. The drive knob 21 drives the rotating shaft 22 to rotate in the opposite direction, which in turn drives the drive gear 23 to rotate in the opposite direction. The drive gear 23 drives the moving plate 24 to move in the opposite direction through rack 25, so that the moving plate 24 blocks the first air outlet 111, allowing outside air to enter cavity 114 through air inlet 115 and then be blown out through second air outlet 112, thus changing the air direction. When air exits through first air outlet 111, the air blown out of first air outlet 111 is perpendicular to moving plate 24. When air exits through second air outlet 112, the air blown out of second air outlet 112 forms an angle α with moving plate 24.

[0036] like Figure 6 As shown, in some preferred embodiments, one end of the drive knob 21 has a connecting portion 211, one end of which extends into the interior of the housing 11. A limiting groove 2111 is provided on the outer side wall of one end of the connecting portion 211, and a retaining spring 3 is secured within the limiting groove 2111. This technical solution secures the drive knob 21 to the main body 1, ensuring that the drive knob 21 is firmly installed and not easily loosened or fallen off.

[0037] like Figure 6 As shown, in some preferred embodiments, a sealing ring 4 is fitted onto the connecting portion 211. One side of the sealing ring 4 abuts against the outer wall of the housing 11 of the main body 1, and the other end of the sealing ring 4 abuts against the drive knob 21. This technical solution seals the gap between the connecting portion 211 and the housing 11, preventing air leakage from the gap when the hair dryer is working. This would reduce the airflow from the first air outlet 111 or the second air outlet 112, resulting in a poorer drying effect.

[0038] In some preferred embodiments, a sealing ring 4 is fitted onto the connecting portion 211. One side of the sealing ring 4 abuts against the inner wall of the housing 11 of the main body 1, and the other end of the sealing ring 4 abuts against the retaining spring 3. This technical solution seals the gap between the connecting portion 211 and the housing 11, preventing air leakage from the gap when the hair dryer is working. This would reduce the airflow from the first air outlet 111 or the second air outlet 112, resulting in a poorer hair drying effect.

[0039] In some preferred embodiments, the movable plate 24 is provided with a first opening 241 and a second opening 242. The first opening 241 corresponds to the first air outlet 111. The second opening 242 corresponds to the second air outlet 112. In specific applications, if the first air outlet 111 is selected for airflow, the switching mechanism 2 is in a first state (e.g., Figure 4 As shown), at this time, the first opening 241 is connected to the first air outlet 111, and the second opening 242 is misaligned with the second air outlet 112 (i.e., the second opening 242 and the second air outlet 112 are not connected). External air enters the cavity 114 through the air inlet 115 and then exits through the first opening 241 and the first air outlet 111. If the second air outlet 112 is selected for air outlet, the switching mechanism 2 is placed in the second state (e.g., ...). Figure 5 As shown in the diagram, at this time, the second opening 242 is connected to the second air outlet 112, and the first opening 241 is misaligned with the first air outlet 111 (i.e., the first opening 241 and the first air outlet 111 are not connected). External air enters the cavity 114 through the air inlet 115 and is then blown out through the second opening 242 and the second air outlet 112. With this technical solution, compared to not having the first opening 241 and the second opening 242 on the movable plate 24, the travel distance of the movable plate 24 is shortened when switching back and forth between the first air outlet 111 and the second air outlet 112, thereby reducing the switching time and effectively improving the switching efficiency.

[0040] In some preferred embodiments, the movable plate 24 is provided with a guide limiting strip 243, and the inner sidewall of the housing 11 of the main body 1 is provided with a guide limiting groove 113. The guide limiting strip 243 is located in the guide limiting groove 113 and can move within the guide limiting groove 113. When the movable plate 24 moves, the guide limiting strip 243 cooperates with the guide limiting groove 113 to ensure the moving accuracy of the movable plate 24. In addition, when the movable plate 24 moves into position, the end of the guide limiting strip 243 will abut against the end sidewall of the guide limiting groove 113. At this time, the drive knob 21 can no longer be rotated to indicate to the consumer that the movable plate 24 has moved into position.

[0041] Specifically, there are two guide limit bars 243 and two guide limit grooves 113. The two guide limit bars 243 are respectively set at both ends on the side of the moving plate 24 away from the drive gear 23, and the two guide limit grooves 113 are respectively opened at the corresponding positions on the inner side wall of the housing 11 of the main body 1 and the side of the moving plate 24 away from the drive gear 23.

[0042] In some preferred embodiments, both the first air outlet 111 and the second air outlet 112 include a plurality of through holes 1111, which are arranged in a straight line at intervals. This technical solution helps to disperse the airflow more evenly, reduce turbulence, and thus make the blown air more stable, thereby improving the hair drying efficiency.

[0043] In some preferred embodiments, the sidewall of the housing 11 of the main body 1 has a flat portion 116, and both the first air outlet 111 and the second air outlet 112 are formed on the flat portion 116, with the first air outlet 111 being perpendicular to the flat portion 116. By providing the flat portion 116 on the sidewall of the housing 11 and having both the first air outlet 111 and the second air outlet 112 formed on the flat portion 116, the movable plate 24 can be designed as a simple flat plate structure, which is convenient for processing and production.

[0044] In some preferred embodiments, the number of drive gears 23 and racks 25 are both two. The two drive gears 23 are respectively sleeved on both ends of the rotating shaft 22, and the two racks 25 are respectively disposed on both ends of the moving plate 24. The two drive gears 23 mesh with the two racks 25 respectively. With this technical solution, compared with using one drive gear 23 and one rack 25, when the drive knob 21 is rotated, the torque can be transmitted to both ends of the moving plate 24 through the rotating shaft 22 at the same time, so that both ends of the moving plate 24 are subjected to force at the same time, ensuring that the moving plate 24 is subjected to force evenly. This ensures that the moving plate 24 can completely block the first air outlet 111 or the second air outlet 112 after it is moved into position, avoiding the situation where insufficient blocking causes the first air outlet 111 and the second air outlet 112 to vent air at the same time.

[0045] In summary, in one or more embodiments of this utility model, the adjustable airflow hair dryer of this utility model has a switching mechanism set in the main body, so that the switching mechanism can block the first air outlet or the second air outlet, thereby realizing the change of airflow direction of the hair dryer to meet different user needs.

[0046] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
