[0012] 1. The central axis of the ventilation port of this utility model is inclined at 60 degrees away from the direction of gaseous fluid flow in the ventilation channel. The funnel-shaped channel is conducive to reserving a cavity for the high-velocity gaseous fluid to expand, thereby cooling the fluid introduced into the ventilation channel. This can enhance the ventilation and heat exchange efficiency between the fluid in the ventilation channel and the fluid in the ventilation box. When the fluid is introduced into the inclined ventilation port, the fluid pressure outside the ventilation channel is reduced, which expands the coverage area of ​​the fluid in the ventilation box moving towards the outer side wall of the ventilation channel, enhances the degree of turbulence of the fluid in the ventilation box, and optimizes the gas environment quality in the elevator.

The limiting frame and ventilation channel are connected by connecting plates. When assembling the ventilation channel, it is assembled from the opening via the assembly frame. The two sides of the ventilation channel are connected to… The inner walls of the ventilation box are movable and connected, with the first channel on both sides of the ventilation channel extending into the second locking ring in the through groove. The first locking ring and the second locking ring are in contact with each other, and the first channel is connected to the through groove, which facilitates the assembly of the ventilation channel. When it is necessary to clean the air inlets on the ventilation channel, the fasteners on the assembly frame and the opening on the ventilation box are removed, and the ventilation channel is taken out of the ventilation box through the assembly frame, which facilitates the cleaning of the air inlets on the ventilation channel, ensures fluid flow in the air inlets, facilitates smooth ventilation of the elevator, and is highly practical.

[0014] 3. This utility model, through the movable connection of the guide block and the guide channel, facilitates the alignment and assembly of channel one within the locking ring two. When assembling the ventilation channel, the guide block outside the connecting piece is slid into the guide channel via the assembly frame, and the ventilation channel is moved and assembled into the ventilation box, so that channel one is aligned and assembled within the locking ring two. This facilitates the assembly and disassembly of the ventilation channel, making the operation convenient and highly practical.

An opening 201 is reserved at the upper end of the ventilation box 200. An assembly frame 202 is installed on the opening 201 via fasteners. An assembly port 203 is reserved on the assembly frame 202. A screening plate 204 is installed on the assembly port 203 via fasteners. A ventilation channel 400 is installed inside the assembly frame 202 via an assembly unit 500.

[0025] The lower end of the ventilation box 200 is fixedly connected to a flange 206, and a limiting groove 207 is reserved on the flange 206. A limiting rod 102 is fixedly connected to the outside of the ventilation groove 101. The limiting rod 102 matches the limiting groove 207 and is threaded to a nut.

[0026] The ventilation channel 400 includes a first channel 402, a second channel 403, and ventilation ports 401. The first channel 402 is funnel-shaped and is fixedly connected to the second channel 403. Ventilation ports 401 are reserved on both the second channel 403 and the pair of first channels 402. Several ventilation ports 401 are arranged at equal intervals on the first channel 402 and the second channel 403. The central axis of the ventilation ports 401 is inclined at a 60-degree angle away from the direction of gaseous fluid flow in the ventilation channel 400. The funnel-shaped channel is conducive to high-velocity gaseous fluid. The reserved expansion cavity cools the fluid introduced into the ventilation channel 400, thereby enhancing the ventilation and heat exchange efficiency between the fluid in the ventilation channel 400 and the fluid in the ventilation box 200. When the fluid is introduced into the inclined ventilation port 401, the fluid pressure outside the ventilation channel 400 is reduced, expanding the coverage area of ​​the fluid in the ventilation box 200 moving towards the outer sidewall of the ventilation channel 400, enhancing the turbulence of the fluid in the ventilation box 200, and optimizing the gas environment quality inside the elevator.

[0027] A limiting frame 302 is fixedly connected inside the assembly frame 202, and the limiting frame 302 is movably connected to the opening 201.

[0028] The assembly unit 500 includes a connecting piece 501, a locking ring 502, and a locking ring 503. The connecting piece 501 is fixedly connected to the outer wall of the channel 402.

The locking ring 502 is assembled on the part of the channel 402 facing away from the channel 403. The locking ring 502 and the locking ring 503 have the same size and are matched with the channel 402.

[0029] The installation of the assembly frame 202 and assembly unit 500 facilitates the assembly, disassembly, and maintenance of the screening plate 204 and the ventilation channel 400, ensuring smooth elevator ventilation and optimizing the gas environment quality inside the elevator. The screening plate 204, mounted on the assembly frame 202, screens dust particles carried in the fluid entering the ventilation box 200. The fasteners facilitate the removal and cleaning of the screening plate 204. The limiting frame 302 is connected to the ventilation channel 400 via a connecting piece 501. When assembling the ventilation channel 400, it is assembled from the opening 201 via the assembly frame 202. The two sides of the ventilation channel 400 are flush with the inner wall of the ventilation box 200. The movable connection allows the first channel 402 on both sides of the ventilation channel 400 to extend into the second locking ring 503 in the through groove 600. The locking ring 502 and the second locking ring 503 are in contact with each other. The first channel 402 is connected to the through groove 600, which facilitates the assembly of the ventilation channel 400. When it is necessary to clean the air vents 401 on the ventilation channel 400, the fasteners on the assembly frame 202 and the opening 201 on the ventilation box 200 are removed. The ventilation channel 400 is then removed from the ventilation box 200 via the assembly frame 202, which facilitates the cleaning of the air vents 401 on the ventilation channel 400, ensures fluid flow in the air vents 401, and facilitates smooth ventilation in the elevator. It is highly practical.

The guide block 504 is movably connected to the guide channel 205. The movable connection between the guide block 504 and the guide channel 205 facilitates the alignment and assembly of the first channel 402 within the second locking ring 503. When assembling the ventilation channel 400, the guide block 504 outside the connecting piece 501 is slid into the guide channel 205 via the assembly frame 202, and the ventilation channel 400 is moved and assembled into the ventilation box 200, so that the first channel 402 is aligned and assembled within the second locking ring 503. This facilitates the assembly and disassembly of the ventilation channel 400, making the operation convenient and highly practical.
