The inner wall of ferrule 4 and threaded sleeve 6 is movably sleeved with the two ends of rotating shaft 2, this connection mode not only ensures that rotating shaft 2 can rotate freely, but also provides stable support.

[0027] Working principle:

[0028] Firstly, the built-in wind speed detection device is installed in the inner wall of the air outlet of the air pipe, when air flow passes through the device, the air flow will impact the spiral blade 1. Because the spiral blade 1 has a specific spiral shape, under the action of the air flow, the spiral blade 1 will produce a rotating motion around the rotating shaft 2. When the spiral blade 1 rotates, the magnet 12 also rotates. Because the magnet 12 is close to the magneto-electric sensor 11 in the inner wall of the mounting frame 3, when the magnet 12 rotates and passes through the magneto-electric sensor 11, the magnetic field around the magneto-electric sensor 11 will change. According to the principle of electromagnetic induction, the change of the magnetic field will cause the magneto-electric sensor 11 to generate an induced electromotive force. The frequency of the induced electromotive force generated by the magneto-electric sensor 11 is related to the rotating speed of the spiral blade 1, and the rotating speed of the spiral blade 1 is proportional to the wind speed. Through the detection and calculation of the change frequency of the induced electromotive force, the current wind speed value can be converted and output in the form of an electric signal, realizing the detection function of the wind speed. In order to adapt to different wind speed measurement ranges or optimize the measurement accuracy, the angle of the spiral blade 1 can be adjusted. The outer wall of the threaded sleeve 6 is sleeved with a threaded ring 8, by rotating the threaded ring 8, due to the threaded cooperation, the threaded ring 8 will move along the axial direction of the threaded sleeve 6. The outer wall of the threaded ring 8 is rotatably sleeved with an adjusting ring 9, the outer wall of the adjusting ring 9 is movably connected with an adjusting rod 10, and the upper end of the adjusting rod 10 is rotatably connected with the spiral blade 1. When the threaded ring 8 moves, the adjusting ring 9 will move together, and the movement of the adjusting ring 9 is transmitted to the spiral blade 1 through the adjusting rod 10, so as to change the included angle between the spiral blade 1 and the air flow, and realize the adjustment of the angle of the spiral blade 1. Different inclinations can adapt to the measurement of different wind speed ranges, when the wind speed is low, the inclination of the fan blade is increased, so that the spiral blade 1 is more easily blown, and the sensitivity of the measurement is improved, when the wind speed is high, the inclination of the spiral blade 1 is reduced, so as to prevent the spiral blade 1 from being damaged due to too high rotating speed, and ensure the accuracy of the measurement.
