Ventilation exhaust fan assembly in elevator

Abstract

The invention discloses a ventilation exhaust fan assembly in an elevator. The assembly comprises an elevator car, a partition plate is fixedly connected to the inner wall of the elevator car, a plurality of first through holes are evenly formed in the middle of the partition plate, a shell is movably arranged on the inner wall of the partition plate, and a movable hole is formed in the side wall of the end, corresponding to the inner position of the partition plate, of the shell; and an annular mounting groove is formed in the inner wall of the end, corresponding to the movable hole, of the partition plate, and the inner wall of the movable hole is movably connected with a mounting block. Two extrusion blocks are pressed through the thumb and the middle finger, a double-end telescopic rod and a damping spring are in a compressed state till the double-end telescopic rod and the damping spring cannot be compressed again, at the moment, the mounting block is completely located on the inner wall of the movable hole, and an air inlet box and the shell can be pulled out from the inner wall of the partition plate; and at the moment, a first soft magnet and a second soft magnet are separated, a first filter screen is replaced and cleaned, operation is easy, use is convenient, and therefore the purposes of being convenient to disassemble and clean can be achieved.

Description

technical field [0001] The invention relates to the technical field of exhaust fans, in particular to an elevator interior ventilation and exhaust fan assembly. Background technique [0002] In people's lives, the popularization and application of elevators has brought convenience to people. As an important means of transportation for transporting people and goods, elevators have been fully integrated into our lives. As the direct place to carry people, the elevator car has higher and higher requirements. In addition to the normal use function, it also has more humanized requirements for its additional functions. Due to the small space of the elevator, the air flow is relatively poor. In order to improve the experience of passengers, most elevators are equipped with ventilation devices. The ventilation of the elevator is mainly through the exhaust fan installed on the car roof. When the elevator is powered on, the exhaust fan blows air , to realize the air flow in the car,...

Problems solved by technology

[0003] However, when the prior art is actually used, the exhaust fan will discharge the air in the elevator for a long time to filter and sterilize, which will cause the filter screen to be full of dust and be inconvenient to disassemble and clean up.
