The quick-release assembly 2 includes a rectangular pipe 201 located on the top of the base plate 1, and a trapezoidal pipe 202 is provided on the rear end surface of the rectangular pipe 201. Multiple sets of partitions 203 are fixed to the inner wall of the rectangular pipe 201, and filter plates 204 are provided on the inner side of the partitions 203. Multiple sets of rectangular grooves 205 are formed on the top surface of the rectangular pipe 201, and multiple sets of through holes 206 are formed on the surface of the rectangular pipe 201. The top of the rectangular pipe 201 is provided with a recess 207, and a connecting cylinder 208 is fixed on the side surface of the recess 207. A sliding groove 209 is provided on the surface of the connecting cylinder 208, and a spring 210 is provided inside the connecting cylinder 208. A protruding post 211 is provided inside the connecting cylinder 208, and a sliding post 212 is fixed on the surface of the protruding post 211. A cylinder 213 is fixed on the top surface of the rectangular pipe 201, and a limit block 214 is installed on the surface of the cylinder 213 through a rotating shaft. A top cover 215 is provided on the surface of the rectangular pipe 201, and a slot 216 is provided on the surface of the top cover 215.

[0025] like Figures 1-5 As shown, a limit post 217 is fixed on the bottom surface of the recess 207, and a threaded post 218 is fixed on the bottom surface of the recess 207. The surface of the threaded post 218 is connected to a limit nut 219 by a thread.

The protrusion 221, together with the locking hole 6 at the bottom of the base plate 1, allows multiple sets of devices to be stacked to improve the ventilation effect.

[0037] 2. The limiting component 3 is provided with a sleeve 301 and a protruding post 304. When the user slides the protruding post 304, the protruding post 304 moves, thereby separating the protruding post 304 from the rectangular pipe 201. By sliding the trapezoidal pipe 202, the trapezoidal pipe 202 can be disassembled, which improves practicality.

[0038] In this technical solution, when the gas concentration sensor 220 detects that the gas concentration is too high, the gas concentration sensor 220 sends an electrical signal to the microprocessor 224. The microprocessor 224 controls the frequency converter 225 to control the wind speed of the axial flow fan 222. The surface of the rectangular pipe 201 is provided with a second protrusion 221, which, together with the locking hole 6 at the bottom of the base plate 1, allows multiple sets of devices to be stacked to improve the ventilation effect. When it is necessary to disassemble the filter plate 204, the top cover 215 can be disassembled by rotating the limiting block 214 and sliding the top cover 215. At the same time, the sliding column 212 can be slid, which can drive the first protrusion 211 to slide, thereby... The protruding post 211 separates from the filter plate 204, making it easier to disassemble the filter plate 204. Disassembling and installing the filter plate 204 is more convenient. The concave hole 207 can be disassembled by turning the limit nut 219. At the same time, the rectangular groove 205 and through hole 206 on the surface of the rectangular pipe 201 can be used to install the filter plate 204 according to actual needs. When it is necessary to disassemble the trapezoidal pipe 202, the sliding post 205 can be slid, which can drive the protruding post 304 to slide, thereby separating the protruding post 304 from the rectangular pipe 201. The trapezoidal pipe 202 can then be disassembled by sliding the trapezoidal pipe 202, which improves practicality.
