Description

Technical Field

[0001] This application relates to the technical field of ventilation equipment, and in particular to a fan. Background Technology

[0002] A fan is a machine that uses input mechanical energy to increase gas pressure and discharge gas. Common fans include ventilators, blowers, wind turbines, and centrifugal fans. Centrifugal fans are a branch of industrial fans and are mostly used in industrial sites for ventilation, air extraction, conveying, and drying. When the motor rotates, the impeller of the centrifugal fan also rotates. The rotation of the impeller generates centrifugal force, which throws air out of the impeller. The air collected in the casing after being thrown out of the impeller is discharged from the ventilator outlet and flows into the pipeline due to its slow speed and high pressure. When the air in the impeller is discharged, a negative pressure is formed, and the air outside the intake port is forced back into the impeller under the action of air pressure. The impeller rotates continuously, and the air flows continuously in the pipeline under the action of the ventilator. Centrifugal fans realize the conversion of wind energy into kinetic energy through this working principle. Existing fans include rotating components and fixed components. The rotating components include several impellers and rotating rings. Several impellers are fixedly connected to the rotating rings. The fixed components include the housing and the motor used to drive the rotating rings to rotate.

[0003] Regarding the aforementioned technologies, the inventors believe that the fan consists of multiple components, is heavy, and needs to be used in various locations, making it inconvenient to move. Utility Model Content

[0004] To facilitate the movement of the fan, this application provides a fan.

[0005] The wind turbine provided in this application adopts the following technical solution:

[0006] A fan includes a fan, a support frame, and rollers. The support frame includes a first connecting rod, a second connecting rod, and a third connecting rod. The first connecting rod and the second connecting rod are disposed on both sides of the fan. The third connecting rod is disposed between the first connecting rod and the second connecting rod. The fan is disposed between the first connecting rod and the second connecting rod. Two rollers are provided. The two rollers are rotatably connected to the first connecting rod via a rotating shaft. The rollers are located on the upper side of the third connecting rod.

[0007] With the above technical solution, when it is necessary to move the fan, the second connecting rod can be held by hand to lift the fan at an angle. At this time, the rollers are in contact with the ground, which facilitates the movement of the fan.

[0008] Optionally, a gripping part is provided at the upper middle part of the first connecting rod.

[0009] The above technical solution allows the fan to be moved by hand, making the fan easier to move.

[0010] Optionally, both the first connecting rod and the second connecting rod are provided with a stop part at their bottom.

[0011] With the above technical solution, when the fan is moved to the designated location, the stop part contacts the ground, increasing the friction between the fan and the ground, making the fan more stable.

[0012] Optionally, the fan is rotatably connected between the first connecting rod and the second connecting rod via a rotating shaft. A fixing member is provided on the side wall of the first connecting rod. The fixing member includes a rotating disk, a fixing column, and a connecting block. The rotating disk is disposed on the side wall of the fan, and the connecting block is disposed on the side wall of the first connecting rod. The fixing column is slidably inserted into the connecting block. The rotating disk has multiple fixing holes for the fixing column to be inserted. The multiple fixing holes are evenly spaced along the circumferential axis of the rotating disk.

[0013] With the above technical solution, when it is necessary to adjust the angle of the fan, the fixing column can be pulled out, the fan can be rotated, and when the fan is rotated to the designated position, the fixing column can be inserted into the fixing hole in sequence to fix the angle of the fan, which facilitates the adjustment of the fan angle.

[0014] The beneficial effects of this utility model are as follows: when it is necessary to move the fan, the second connecting rod can be held by hand to lift the fan at an angle. At this time, the rollers are in contact with the ground, which facilitates the movement of the fan. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0018] This application discloses a fan.

[0019] Reference Figure 1The fan 1 includes a fan 1, a bracket 2, and rollers 3. The bracket 2 includes a first connecting rod 21, a second connecting rod 22, and a third connecting rod 23. The first connecting rod 21 and the second connecting rod 22 are located on both sides of the fan 1. The third connecting rod 23 is located between the first connecting rod 21 and the second connecting rod 22. The fan 1 is located between the first connecting rod 21 and the second connecting rod 22. There are two rollers 3. The two rollers 3 are rotatably connected to the first connecting rod 21 through a rotating shaft. The rollers 3 are located on the upper side of the third connecting rod 23.

[0020] When it is necessary to move the fan 1, the second connecting rod 22 can be held by hand to lift the fan 1 at an angle. At this time, the roller 3 will contact the ground, which facilitates the movement of the fan 1.

[0021] A gripping part 231 is provided at the upper middle part of the first connecting rod 21.

[0022] The handheld grip 231 allows for easy movement of the fan 1.

[0023] Both the first connecting rod 21 and the second connecting rod 22 are provided with a stop part 4 at their bottom.

[0024] When the fan 1 is moved to the designated location, the stop part 4 contacts the ground, increasing the friction between the fan 1 and the ground, making the fan 1 more stable.

[0025] The fan 1 is rotatably connected between the first connecting rod 21 and the second connecting rod 22 via a rotating shaft. A fixing member 5 is provided on the side wall of the first connecting rod 21. The fixing member 5 includes a rotating disk 51, a fixing post 52, and a connecting block 53. The rotating disk 51 is disposed on the side wall of the fan 1, and the connecting block 53 is disposed on the side wall of the first connecting rod 21. The fixing post 52 is slidably inserted into the connecting block 53. The rotating disk 51 has a plurality of fixing holes 511 for the fixing post 52 to be inserted. The plurality of fixing holes 511 are evenly spaced along the circumferential axis of the rotating disk 51.

[0026] When it is necessary to adjust the angle of the fan 1, the fixing column 52 can be pulled out and the fan 1 can be rotated. When the fan 1 is rotated to the specified position, the fixing column 52 can be inserted into the fixing hole 511 in sequence to fix the angle of the fan 1, which facilitates the adjustment of the angle of the fan 1.

[0027] The implementation principle of a fan 1 in this application embodiment is as follows: when it is necessary to adjust the angle of the fan 1, the fixing column 52 can be pulled out, the fan 1 can be rotated, and when the fan 1 is rotated to the specified position, the fixing column 52 is inserted into the fixing hole 511 in sequence to fix the angle of the fan 1, which facilitates the adjustment of the angle of the fan 1.
