[0013] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0014] like Figure 1 As shown, an embodiment of the present application discloses a hair dryer with variable wind speed, comprising a hair dryer housing 1, an air outlet 3 is provided on the hair dryer housing 1, a wind wheel is provided in the hair dryer housing 1, a motor 2 for driving the wind wheel to rotate is provided on the hair dryer housing 1, a driving end of the motor 2 extends into the hair dryer housing 1 and is connected with the wind wheel, an air inlet is provided on the hair dryer housing 1 on a side facing the wind wheel, a protruding air inlet cover 4 is provided at the air inlet, a through hole 5 for air intake is provided on the air inlet cover 4, an inlet slot is provided on one side of the air inlet cover 4, an adjustment baffle 6 which can pass through the inlet slot to block the through hole 5 is provided on one side of the inlet slot.

[0015] Specifically, when the hair dryer is in use, the motor 2 drives the wind wheel to rotate. Under the action of the wind wheel, wind enters from the air inlet and is blown out from the air outlet 3. When the adjustment baffle 6 does not block the air inlet, the wind speed at this time is the maximum. When the wind speed needs to be reduced, the adjustment baffle can be passed through the inlet slot to block the through hole 5 on the air inlet cover 4, so as to adjust the air inlet to a suitable size, thereby realizing wind speed adjustment.

[0016] The hair dryer in the present application can block the air inlet by adjusting the setting of the baffle 6, thereby adjusting the size of the air inlet, and the blowing speed will change with the change of the air inlet area, thereby adjusting the blowing speed. This speed regulation device has the characteristics of low cost and simple and easy control.

[0017] In this embodiment, the fan housing is provided with a first L-shaped positioning strip 7 and a second L-shaped positioning strip 8 on one side of the inlet groove, a first groove is formed between the first L-shaped positioning strip 7 and the hair dryer housing 1, a second groove is formed between the second L-shaped positioning strip 8 and the hair dryer housing 1, and both sides of the adjustment baffle 6 are respectively located in the first groove and the second groove.

[0018] Specifically, the two sides of the adjustment baffle 6 are respectively located in the first groove and the second groove, that is, the adjustment baffle 6 is inserted into the first L-shaped positioning strip 7 and the second L-shaped positioning strip 8. When adjustment is needed, the adjustment baffle 6 can be pulled to move along the first groove and the second groove.

[0019] The above-mentioned structure can facilitate the movement and adjustment of the adjustment baffle 6, and also plays a role in positioning the adjustment baffle 6. When the adjustment baffle 6 is not needed, the adjustment baffle 6 can also be stored in the first groove and the second groove, thereby facilitating the use of the adjustment baffle 6.

[0020] In this embodiment, a handle 9 is provided on the adjustment baffle 6, and the handle 9 includes a positioning portion and a protrusion connected to the positioning portion, and the two ends of the positioning portion extend into the first groove and the second groove respectively, and the protrusion extends out from the surface of the first L-shaped positioning strip 7 and the second L-shaped positioning strip 8.

[0021] Specifically, when it is necessary to pull the adjustment baffle 6 to adjust the size of the air inlet, the movement of the adjustment baffle 6 can be adjusted by pulling the handle 9.

[0022] In this structure, the arrangement of the handle 9 can facilitate pulling the adjustment baffle 6, thereby making adjustment more convenient.

[0023] In this embodiment, a blowing pipe 10 is provided at the air outlet 3 , and the diameter of one end of the blowing pipe 10 connected to the air outlet 3 is larger than the diameter of the other end of the blowing pipe 10 .

[0024] In this structure, the blow pipe 10 is designed so that the diameter of one end connected to the air outlet 3 is larger than the diameter of the other end of the blow pipe 10, so that the wind can undergo a pressurization process when passing through the blow pipe 10, thereby making the blown wind pressure greater and more convenient for cleaning operations.

[0025] In this embodiment, a plurality of blocking sheets 11 are arranged inside the air outlet 3 of the hair dryer housing 1 .

[0026] In this mechanism, the blocking piece 11 can block human fingers, so that human fingers cannot enter the hair dryer housing 1 from the air outlet 3, thereby playing a role of safety protection.

[0027] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
