[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Embodiment, please refer to Figures 1-5 , the present utility model provides a technical solution:

[0028] A roof fan for workshop ventilation includes an air duct 1, and a cleaning component 2 and an auxiliary component 3 are respectively arranged inside the air duct 1, and the auxiliary component 3 is located on the side of the cleaning component 2.

[0029] In this embodiment, according to Figure 1 , Figure 2 , Figure 3 andFigure 4 As shown in the figure, the cleaning component 2 includes a rotating disk 206 inside the air duct 1. A connecting rod 203 is fixedly connected to the side surface of the rotating disk 206. A guide rod 204 is fixedly connected to the side surface of the connecting rod 203. A cleaning brush 205 is fixedly connected to the side surface of the guide rod 204. An installation plate 202 is arranged inside the air duct 1. A filter screen 201 is fixedly connected inside the installation plate 202. The filter screen 201 is located at the opening of the air duct 1. The cleaning brush 205 abuts against the filter screen 201. Four rotating blades 207 are inserted into the side surface of the rotating disk 206. The four rotating blades 207 are all arranged in a circular array with the middle position of the side surface of the rotating disk 206 as the center. Four first insertion rods 208 are arranged on the side surface of the rotating disk 206. The four first insertion rods 208 respectively penetrate through the rotating disk 206 and extend into the four rotating blades 207. The four first insertion rods 208 are all inserted into the rotating disk 206. A second insertion rod 5 is arranged on the side surface of the air duct 1. The second insertion rod 5 penetrates through the air duct 1 and extends into the installation plate 202. The second insertion rod 5 is inserted into the air duct 1. A driving motor 7 is installed inside the air duct 1. The output end of the driving motor 7 is fixedly connected to the installation plate 202. The filter screen 201 is circular. The length of the cleaning brush 205 is the same as the radius of the filter screen 201.

[0030] Among them, since a filter screen 201 is installed at the opening of the air duct 1, foreign dust from the outside can be prevented from entering the air duct 1. When the rotating disk 206 rotates, the connecting rod 203 rotates accordingly, and then the cleaning brush 205 that abuts against the filter screen 201 will clean it, removing the dust on the filter screen 201 and improving the practicability.

[0031] In this embodiment, according to Figure 1 、 Figure 2 and Figure 5 As shown in the figure, the auxiliary component 3 includes an installation groove 301 opened inside the air duct 1. An annular heat dissipation pipe 302 is fixedly connected inside the installation groove 301. A water inlet pipe 303 and a drain pipe 304 are respectively arranged on the side surface of the air duct 1. The water inlet pipe 303 penetrates through the air duct 1 and is fixedly connected to one end of the annular heat dissipation pipe 302. The drain pipe 304 penetrates through the air duct 1 and is fixedly connected to the other end of the annular heat dissipation pipe 302. A wind cap 4 is arranged on the side surface of the air duct 1. A connection hole 6 is opened on the side surface of the wind cap 4. The connection hole 6 is opposite to the position of the air duct 1. Water stop valves 305 are fixedly connected to the outer surfaces of the drain pipe 304 and the water inlet pipe 303. The drain pipe 304 and the water inlet pipe 303 are of the same size.

[0032] Among them, after water is passed through the annular heat dissipation pipe 302, the inside of the air duct 1 can be cooled, and then discharged through the drain pipe 304. Then, it can be recycled in this way, which not only prevents the water temperature inside the annular heat dissipation pipe 302 from rising, but also continuously cools the inside of the air duct 1.

[0033] The working process of the utility model: When the roof fan for workshop ventilation designed by this solution is working, first check whether the device is normal, move the device to a suitable working area, and then fix it. Start the driving motor 7 to drive the rotating disk 206 and the rotating blades 207 to rotate. Since the filter screen 201 is installed at the opening of the air duct 1, it can prevent foreign dust from entering the air duct 1. When the rotating disk 206 rotates, the connecting rod 203 rotates accordingly, and then the cleaning brush 205 in contact with the filter screen 201 will clean it, removing the dust on the filter screen 201 and improving the practicability. Since the rotating blades 207 are inserted into the rotating disk 206 and fixed by the first insertion rod 208, they can be separated after pulling out the first insertion rod 208, thus improving the disassembly and installation efficiency. At the same time, the filter screen 201 is inserted into the second insertion rod 5 through the mounting plate 202, which is convenient for removing the filter screen 201 from the air duct 1. During the working process, the temperature in the air duct 1 will rise. Inject water into the water inlet pipe 303, and the water flow will enter the annular radiating pipe 302. After the annular radiating pipe 302 is filled with water, it can cool the inside of the air duct 1, and then be discharged through the drain pipe 304. In this way, it can be recycled continuously, not only preventing the water temperature in the annular radiating pipe 302 from rising, but also continuously cooling the inside of the air duct 1, thus improving the practicability.

[0034] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
