DETAILED DESCRIPTION

[0016] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0018] like Figure 1As shown, a vibration-reducing and noise-reducing roof fan, in order to reduce vibration and noise, the utility model includes a fan body 1, a fan base 2, a vibration-reducing pad 3, a rotating seat 4, and a fixed seat 6 arranged in sequence from top to bottom, the fixed seat 6 is used to be fixed on the roof, and also includes a plurality of locking units 5 for fixing the fan base 2, the vibration-reducing pad 3, and the rotating seat 4 together, the locking unit 5 has a concave cross-section, and a bolt for positioning is arranged on the lower side of the locking unit 5, the rotating seat 4 is tightened by tightening the bolts, so that the fan base 2, the vibration-reducing pad 3, and the rotating seat 4 are fixed together, when the fan body 1 vibrates, the vibration is partially absorbed by the elastic vibration-reducing pad 3, and there are multiple components between the fan body 1 and the roof, so that the distance between the two becomes larger, or the fan body 1 is placed higher, so that less vibration is transmitted to the roof, and less vibration noise is transmitted into the room. In order to install the heightened fan body 1 on the roof, the rotating seat 4 of the utility model includes a rotating shaft 41, which is rotatably connected to the fixed seat 6. The fixed seat 6 is provided with a stopping mechanism 7 for positioning the rotating shaft 41. The stopping mechanism 7 includes a friction ring 71 with a semicircular cross-section. The surface of the friction ring 71 close to the rotating shaft 41 is provided with a pattern for increasing the friction between the rotating shaft 41. The friction ring 71 is pressed against the rotating shaft 41 to stop the rotating shaft 41 and position the rotating seat 4.

[0019] Specifically, the utility model reduces the vibration transmitted from the fan body 1 to the roof by adding the vibration-damping pad 3. And by loosening the locking unit 5, the fan body 1 can rotate around the vertical center axis of the fan base 2, and the rotating seat 4 can also rotate around the rotating shaft 41, so that the position of the fan body 1 of the utility model is adjustable, or the position of the air outlet 11 of the fan body 1 is adjustable, which is convenient for docking with the ventilation duct.

[0020] Furthermore, the fan body 1 includes an air inlet, on which a filter 12 for filtering air is installed.

[0021] Furthermore, the vibration-damping pad 3 is provided with a plurality of through holes 31 , and the vibration-damping pad is made of rubber material.

[0022] Furthermore, the stop mechanism 7 further comprises a sliding seat 72 fixedly connected to the friction ring 71, the sliding seat 72 is slidably connected to a sliding rod 73, and both ends of the sliding rod 73 are fixedly connected to support seats 74. Specifically, the sliding seat 72 can drive the friction ring 71 to move along the sliding rod 73 to approach or move away from the rotating shaft 41.

[0023] Furthermore, the sliding seat 72 is also rotatably connected to a threaded rod 75, which is threadedly connected to one of the support seats 74, and a handle 76 is fixedly connected to one end of the threaded rod 75 away from the sliding seat 72. Specifically, by rotating the handle 76, the threaded rod 75 drives the sliding seat 72 to move, and after the threaded rod 75 stops rotating, the sliding seat 72 cannot move.

[0024] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
