[0032] A fan main body 1, a support mechanism 2 is arranged on the outer surface of the fan main body 1. The support mechanism 2 includes two side plates 201 respectively fixedly installed on both sides of the fan main body 1. A support frame structure is connected between the two side plates 201. A first fixing bolt 205 is arranged on the support frame structure. A number of third through-holes 207 are arranged on the fan main body 1, and the first fixing bolt 205 is inserted into one of the third through-holes 207.

[0033] For the cylindrical rotor fan provided by the present utility model, through the provided support frame structure, first fixing bolt 205 and third through-hole 207, the fan main body 1 and the support frame structure are rotatably arranged, and the angle is fixed through the cooperation of the first fixing bolt 205 and the third through-hole 207. After loosening the third through-hole 207, the fan main body 1 can be rotated to adjust the angle of the fan main body 1 to meet different usage requirements, and the adjustment process is simple and easy to operate.

[0034] To enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0037] Example 1, please refer to Figures 1 - 3 , a cylindrical rotor fan, including a fan main body 1, a support mechanism 2 is arranged on the outer surface of the fan main body 1. The support mechanism 2 includes two side plates 201 respectively fixedly installed on both sides of the fan main body 1. A support frame structure is connected between the two side plates 201. A first fixing bolt 205 is arranged on the support frame structure. A number of third through holes 207 are arranged on the fan main body 1, and the first fixing bolt 205 is inserted into one of the third through holes 207. Through the arranged support frame structure, first fixing bolt 205 and third through hole 207, the fan main body 1 and the support frame structure are rotatably arranged, and the angle is fixed through the cooperation of the first fixing bolt 205 and the third through hole 207. After loosening the third through hole 207, the fan main body 1 can be rotated to realize the angle adjustment of the fan main body 1, meeting different usage requirements, and the adjustment process is simple and easy to operate.

[0038] Furthermore, as Figures 1 - 3 shown, the support frame structure includes two support plates 204. The two support plates 204 are respectively arranged on the sides of the two side plates 201 away from each other. The first fixing bolt 205 is arranged on the support plate 204, and the support plate 204 can play a supporting role for the fan main body 1.

[0039] Furthermore, as Figures 1 - 3 shown, a support ring 208 is fixedly connected between the bottoms of the two support plates 204. The support ring 208 and the support plate 204 can cooperate to support the fan main body 1.

[0040] Furthermore, the inner diameter of the support ring 208 is greater than or equal to the outer diameter of the fan main body 1. Referring to Figure 4 , the support ring 208 can be sleeved on the outer surface of the fan main body 1. Such a setting can not only reduce the overall volume and facilitate carrying, but also form another installation method. For example, after opening a hole in the wall, the fan main body 1 is installed into the hole, and at this time, the support ring 208 can be fixed to the wall through the installation hole 209 and expansion bolts.

[0041] Embodiment 2 further optimizes the cylindrical rotor fan provided in Embodiment 1. Specifically, as Figures 1 - 3 shown, a first through hole 202 is provided between the side plate 201 and the fan main body 1. A second fixing bolt 206 is provided on the support plate 204. One end of the second fixing bolt 206 is inserted into the first through hole 202. The mutual cooperation of the second fixing bolt 206 and the first through hole 202 can realize the connection between the support plate 204 and the side plate 201.

[0042] Furthermore, as Figures 1 - 2 shown, a second through hole 203 is also provided between the side plate 201 and the fan main body 1.

[0043] Furthermore, as Figure 1 shown, a plurality of mounting holes 209 are provided on the support ring 208. The mounting holes 209 are used for the auxiliary fixation of the support ring 208, that is, the support ring 208 can be fixed on the support plane by using bolts to pass through the mounting holes 209.

[0044] Furthermore, isolation parts are provided at both ends of the fan main body 1. The isolation parts are used for dust isolation to reduce the situation of dust adhering to the inside of the fan main body 1.

[0045] Embodiment 3 further optimizes the cylindrical rotor fan provided in Embodiment 1 or 2. Specifically, as Figure 1 shown, the isolation part includes a support ring 3 installed on one side of the fan main body 1. A filter screen 301 is fixedly installed in the middle of the support ring 3. The air entering the fan main body 1 can be filtered through the filter screen 301 to reduce the situation of dust adhering to the inside of the fan main body 1.

[0046] Furthermore, the support ring 3 and the fan main body 1 are connected by screws. The screw connection makes the support ring 3 detachable for the convenience of cleaning the filter screen 301.

[0047] The usage process of the cylindrical rotor fan provided by the present utility model is as follows:

[0048] Referring to Figure 1 , when the angle of the fan main body 1 needs to be adjusted, loosen the first fixing bolt 205 so that the first fixing bolt 205 is separated from the third through hole 207, and then rotate the fan main body 1 so that the fan main body 1 rotates around the second fixing bolt 206. After adjustment, screw on the first fixing bolt 205 so that the first fixing bolt 205 is inserted into the corresponding third through hole 207 to realize the fixation after the angle adjustment of the fan main body 1;

[0049] Figure 1 Switch to Figure 4When, unscrew the first fixing bolt 205 and the second fixing bolt 206, separate the support plate 204 from the side plate 201, insert the support ring 208 together with the fan main body 1, then connect the second fixing bolt 206 with the second through hole 203, and connect the first fixing bolt 205 with the first through hole 202, that is, as Figure 4 shown. In this state, the overall volume is reduced, which is convenient for transportation, and the fan main body 1 can be installed on the wall with holes;

[0050] Figure 4 Switch to Figure 1 When, unscrew the first fixing bolt 205 and the second fixing bolt 206, separate the support ring 208 from the fan main body 1, erect the support plate 204, connect the second fixing bolt 206 with the first through hole 202, and connect the first fixing bolt 205 with the third through hole 207.
