Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] See Figures 1-2 A soundproof fan with adjustable wind speed includes a mounting plate body 1, a fan housing 2, a soundproof speed regulating component 3, and a limiting component 4. The fan housing 2 is installed on the top outer wall of the mounting plate body 1, and the soundproof speed regulating component 3 is installed on the fan housing 2. The limiting component 4 is installed on the bottom outer wall of the mounting plate body 1. Clips 6 are fixedly distributed on one side outer wall of the arc-shaped guide plate 307. The fan housing 2 has slots 5 distributed at the corresponding positions of the clips 6. The clips 6 can be engaged with the slots 5 to facilitate the installation of the arc-shaped guide plate 307 into the equipment. The mounting hole 7 is opened on the middle outer wall of the mounting plate body 1. The mounting hole 7 on the mounting plate body 1 is fitted into the designated position to facilitate the installation of the equipment.

[0020] The sound insulation and speed control assembly 3 includes a motor base 301, a brushless motor 302, a motor shaft 303, an impeller pressure plate 304, an impeller fixing nut 305, an impeller 306, an arc-shaped guide plate 307, sound insulation cotton 308, and a fan motor drive operation panel 309. The motor base 301 is fixedly connected to the top outer wall of the fan housing 2. The brushless motor 302 is mounted on the top outer wall of the motor base 301. The bottom end of the output shaft of the brushless motor 302 is fixedly connected to the motor shaft 303. Impellers are installed inside the fan housing 2. The impeller 306 has a bottom end that passes through the interior of the motor shaft 303. An impeller pressure plate 304 is installed on the inner wall of the bottom end of the impeller 306. An impeller fixing nut 305 is threaded onto the outer wall of the motor shaft 303 located below the impeller pressure plate 304. An arc-shaped guide plate 307 is symmetrically installed on the inner wall of the fan housing 2 located on one side of the impeller 306. Sound insulation cotton 308 is symmetrically installed on the inner walls of both sides of the fan housing 2. A fan motor drive operation panel 309 is installed on the top of the fan housing 2.

[0021] Working principle: When the wind speed needs to be adjusted, the fan motor is started and the operation panel 309 is activated to adjust the speed of the brushless motor 302 on the motor base 301. Then, the brushless motor 302 causes the motor shaft 303 to rotate. The impeller pressure plate 304 and the impeller fixing nut 305 are then fixed to the motor shaft 303. The motor shaft 303 drives the impeller 306 to rotate. At this time, the air direction is adjusted by the arc-shaped guide plate 307, and the air is blown out through the air outlet on the fan casing 2. The noise generated is then reduced by the sound insulation cotton 308. With one air inlet and two air outlets, and the air outlets are covered with sound insulation cotton 308, the noise is reduced inside the fan. Moreover, the air outlet is 1.5-2 times larger than the air inlet, which maximizes the fan effect and avoids the air volume being affected by the air outlet being too small.

The limiting slider 405 and the limiting groove 408 are T-shaped. One side of the limiting slider 405 is limited and connected to the inside of the limiting groove 408. The limiting groove 408 on the clamping arc plate 407 is pushed to move up and down along the limiting slider 405 on the guide rod 404, so that the limiting bar 409 on the clamping arc plate 407 is aligned with the groove.

[0024] The mounting hole 7 on the mounting plate body 1 is fitted into the designated position. Then, according to the position of the groove, the limiting slide 408 on the clamping arc plate 407 is pushed to move along the limiting slider 405 on the guide rod 404, so that the limiting bar 409 on the clamping arc plate 407 is aligned with the groove. At this time, the rotating handle 4010 is turned to rotate the threaded rod 406. Then, under the action of the threaded hole 403, the threaded rod 406 is pressed against the clamping arc plate 407.
