In this embodiment, the upper transverse tube 101, the vertical tube 102 and the lower transverse tube 103 are rectangular tubes, and the cross-sectional dimensions of the three tubes are corresponding and welded into a whole, so that the circulating fan device is guaranteed to have only one air inlet and one air outlet.
The overall shape of the filter screen frame unit is a lateral "U", and the opening 104 is disposed on a side surface of the standpipe 102 away from the upper transverse pipe 101 and the lower transverse pipe 103, so as to be used for assembling and disassembling the fan blades 13 and the filter screen frame unit 3.
The mounting hole 105 may be configured to pass through the motor shaft of the motor 11, so as not to touch the motor shaft as much as possible. Thus, the mounting holes 105 are on the side of the lower cross tube 103 that is closer to the standpipe 102, i.e., directly below the standpipe 102.
The opening combination pipe unit 1 further includes a cover plate 106 provided on the opening 104, and a reinforcing bolt 107 provided on the cover plate 106 and used for connecting the screen frame unit 3.
In this embodiment, the cover 106 is further provided with a mounting bolt for self-fixing. To this end, the cover 106 has at least the following 2 roles:

The support frame unit 4 includes a screw plate 401 provided on the lower cross pipe 103, and an L-shaped plate 402 provided on the screw plate 401 at a position below the mounting hole 105 and for supporting the motor 11.
In this embodiment, the screw plate 401 and the L-shaped plate 402 are integrally formed, and have a zigzag shape, so that the motor 11 is fully supported, and the fan blades 13 can be stably driven to rotate, so that the most basic hot air circulation function can be effectively performed.
When the motor 11 and/or the connecting shaft 12 need to be maintained and replaced, the screw plate 401 is removed, the support frame unit 4 is moved down, the motor 11 is pulled down, and finally the connection and fixation relationship between the motor shaft and the connecting shaft 12 is released.
The opening combination pipe unit 1 further includes 2 inclined plates 109 provided in the standpipe 102 at positions on both sides of the opening 104, respectively, for guiding the hot air.
In this embodiment, the inclined plate 109 is rectangular in shape, and the four sides of the inclined plate are welded to the open combined pipe unit 1 sufficiently, so as to avoid leaving gaps and entering ash.
In addition, the inclined plate 109 directly serves to bend the original right angle inside the opening combination pipe unit 1 into an obtuse angle, thereby reducing the loss of the kinetic energy of the air flow, and the final effect is to reduce the energy consumption of the motor 11.
The opening combination pipe unit 1 further includes a limiting hole 110 provided on the inclined plate 109 below and for passing through the connection shaft 12.
In this embodiment, the limiting hole 110 is vertically aligned with the mounting hole 105, and the former serves as a function supplement structure of the 2 limiting rings 201, so that the rotation of the connecting shaft 12 is smoother. The limiting holes 110 can also be provided with balls or lubricating grease, so that the balls or the lubricating grease can be prevented from being worn out greatly.
