[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0019] Reference Figure 1-Figure 3 As shown, a device for measuring the air volume of a hair dryer includes a cabinet 1, a movable slide 3 is installed on the upper end of the cabinet 1, a second threaded rod 21 is rotatably installed inside the movable slide 3, the left end of the second threaded rod 21 extends to the outside of the movable slide 3 and is fixedly connected to a hand-cranked wheel 2, and the outer surface of the second threaded rod 21 is threadedly connected to a second slider 22. By rotating the hand-cranked wheel 2, the second threaded rod 21 can be driven to rotate, and then the second slider 22 can be moved. In the process of the second slider 22 moving left or right, the locking device 4, the vertical body 5, and the linear The slide 6, the angle adjuster 7 and the hair dryer body 8 move to the left or right. The method of driving the vertical body 5 to move is not limited to the hand-cranked wheel 2. It can also be driven by a motor. The hand-cranked wheel 2 is only one of the possible driving methods. The upper end of the second slider 22 is provided with a vertical body 5. The right side of the vertical body 5 is connected to a linear slide 6. The right end of the linear slide 6 is slidably connected to the angle adjuster 7. The front end of the angle adjuster 7 is installed with a locker 4. The locker 4 can fix the position of the angle adjuster 7. At the same time, the angle adjuster 7 can adjust and fix the angle of the hair dryer 8. A claw-shaped clamp 12 is installed at the right end of the angle adjuster 7, and the hair dryer body 8 is provided inside the claw-shaped clamp 12.

[0020] Reference Figure 1 and Figure 3As shown, a vertical slide 16 is installed inside the front end of the cabinet 1, and the internal thread of the vertical slide 16 is connected to the first threaded rod 19, and the lower end of the vertical slide 16 is fixedly installed with a second motor 17. The second motor 17 and the first motor 14 are stepping motors or servo motors. The output end of the second motor 17 extends to the inside of the vertical slide 16 and is fixedly connected to the lower end of the first threaded rod 19. The outer surface of the first threaded rod 19 is threadedly connected to the first slider 20. The right end of the first slider 20 is installed with a horizontal slide 15. The distance moved each time by the horizontal slide 15 and the vertical slide 16 during the test is 5 mm or an integer multiple of 5 mm. The effective moving distance of the general horizontal slide 15 and the vertical slide 16 is 400 mm. The front end of the horizontal slide 15 is fixed. A first motor 14 is fixedly installed. Driven by the first motor, the first threaded rod rotates, thereby driving the first slider to move up and down. The up and down movement of the first slider can drive the anemometer fixture, the vertical rod, the claw fixture, the straight rod fixture, the first motor and the horizontal slide to move up or down at the same time. A straight rod fixture 13 is provided on the horizontal slide 15. A vertical rod 11 is provided inside the straight rod fixture 13.

[0021] The working principle and usage process of the utility model are as follows: before conducting a test, rotating the hand-cranked wheel 2 drives the second threaded rod 21 to rotate, thereby driving the second slider 22 to move left and right. The left and right movement of the second slider 22 can drive the vertical body 5 to move left and right, thereby driving the hair dryer body 8 to move left and right. According to needs, the left and right positions of the hair dryer body 8 are adjusted so that the outlet plane of the hair dryer body 8 is 200mm away from the anemometer test plane, and then the hair dryer body 8 is moved up and down on the linear slide 6 through the claw-shaped clamp 12. After adjusting the height of the hair dryer body 8, the outlet center position of the hair dryer body 8 is then adjusted to the center position of the anemometer vertical slide 16 and the horizontal slide 15, so that the outlet plane of the hair dryer body 8 is parallel to the anemometer measuring plane, and then fixed by the locker 4. The hair dryer body 8 is then driven by the second motor 17 to rotate the first threaded rod 19, thereby driving the first slider 20 to move up and down. The up and down movement of the first slider 20 can drive the horizontal slide 15 to move up and down, thereby driving the vertical rod 11 to move up and down, until the measuring plane of the anemometer sensor 9 is parallel to the air outlet plane of the hair dryer. Then, the anemometer sensor 9 is aligned with the middle position of the hair dryer body 8. If there are multiple anemometer sensors 9, one of the anemometer sensors 9 is aligned with the middle position of the hair dryer body 8. The anemometer sensor 9 is controlled by the program to move up and down, left and right on the measuring plane. The step distance of each movement is 5mm. The wind speed data of all measuring points with a wind speed exceeding 24m / min are obtained. The expression of the association model is:
