When it is necessary to repair a specific component, the device is not easy to disassemble.

[0004] For this, Chinese Patent Application No. CN202321338693.6 discloses an explosion-proof roof fan, including a bottom plate. Two mounting plates are welded and provided on both sides of the top of the bottom plate. The main body is abutted against the top of the bottom plate. A fixing mechanism is installed between the main body and the mounting plate. Two chutes are opened inside the main body. Four mounting plates are fixedly connected to the top of the bottom plate.

[0038] When specifically arranged, the ventilation assembly 160 includes a mounting plate 161, a motor 162, a rotating shaft 163, and a fan 164.

[0043] The working principle of this quick installation mechanism for a roof fan: When using the quick installation mechanism for a roof fan, by the sliding connection between the L-shaped fixing cylinder 120 and the limiting rod 170, the L-shaped fixing cylinder 120 can be quickly positioned. At this time, pulling the sliding rod 151 drives the slider 152 to move, and compresses the spring 153, so that the sliding rod 151 is disengaged from the clamping connection with the fixing frame 130. Rotating the handle 142 drives the bidirectional lead screw 141 to rotate, so that the two lead screw nut pairs 143 and the clamping plates 144 approach each other to clamp the L-shaped fixing cylinder 120, facilitating the quick installation of the roof fan. Through the reset of the spring 153, the sliding rod 151 is driven to be clamped with the fixing frame 130 again, facilitating the prevention of the rotation of the bidirectional lead screw 141. Driving the rotating shaft 163 and the fan 164 to rotate by the motor 162 facilitates ventilation. While the rotating shaft 163 rotates, it drives the cleaning brush 220 to rotate, facilitating the timely cleaning of the filter screen 210 to avoid blockage, improving the practicability of the device. The dust cleaned out falls into the collection box 240. By the clamping connection between the clamping blocks 250 and the clamping grooves 260, the disassembly and assembly of the collection box 240 can be facilitated for unified treatment.

[0044] It should be noted that the specific model and specification of the motor 162 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail here.

[0045] The power supply and principle of the motor 162 are clear to those skilled in the art and will not be described in detail here.

[0046] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present application, and all should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
