Due to the small space in the elevator car, large flow of people, poor air circulation and other factors, it is necessary to install ventilation devices in the elevator. There are two main installation methods for elevator ventilation devices. One is to install it in the middle of the upper end of the elevator car, and the other is to install it on the back or both sides of the top of the elevator. During the operation of the elevator, air is supplied to the interior of the elevator to maintain air circulation inside the elevator.
[0003] In the prior art, in order to prevent excessive dust from remaining on the filter on the elevator ventilation device, resulting in poor air supply or malfunction of the motor of the air supply device, it is necessary to regularly remove the filter for cleaning, or remove the ventilation device for maintenance. However, the filter and the ventilation device are generally installed on the upper end of the elevator car with bolts. When cleaning the filter later, it is necessary to use tools to remove the bolts one by one to take out the filter. After cleaning, the bolts must be installed one by one to fix the filter. This operation process is cumbersome and time-consuming. Utility Model Content

The motor 6 is fixedly installed on both sides of the inner periphery of the motor base 5 by bolts 16, the fan blades 7 are fixedly connected to the lower driving end of the motor 6, the outer periphery of the motor base 5 is fixedly connected to the inner upper part of the outer shell 3, and the outer periphery of the fan blades 7 is rotatably connected to the inner middle part of the outer shell 3.
[0023] Specifically, when the elevator is in use, the motor 6 is started to drive the fan blades 7 to rotate, and the air outside the elevator is sent into the interior of the elevator car 17 through the mesh of the filter 8. When the motor 6 needs to be inspected, the two sets of limit assemblies are turned counterclockwise around the axis of the outer shell 3 to rotate all the limit buckles 4 to the lower end opening of the limit groove 2, and the outer shell 3 is pulled downward. The air supply assembly can be removed together with the shell assembly, and the motor 6 can be inspected. The limit groove 2 inside the mounting seat 1 cooperates with the limit buckles 4 on the outer periphery of the shell assembly, so that the motor 6 can be quickly removed for inspection.
[0024] In this embodiment, the limit assembly includes a limit plate 10, a limit rod 11, a limit block 12 and a limit spring 13.

When the filter 8 needs to be cleaned, the limit block 12 is rotated to align the limit block 12 with the slot 9, and the limit block 12 is loosened. The limit spring 13 cooperates with the limit plate 10 to drive the limit rod 11 to slide upward inside the limit hole 19, and all the limit components are rotated in sequence. When the limit block 12 of the last set of limit components is rotated to be flush with the slot 9, the filter 8 can be removed from the outer shell. 3 falls off, and the filter screen 8 is easily removed for cleaning through the cooperation of the limit assembly and the shell assembly.
