[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] Please see Figure 1-3 This utility model provides a technical solution: an elevator car ventilation device, including a duct 1, a support mechanism, a dustproof mechanism, and a connecting mechanism; a motor 12 is fixedly installed at the bottom of the duct 1 by a bracket, a fan blade 14 is fixedly installed at the top of the drive shaft of the motor 12, and an iron block 13 is fixedly installed in the middle of the upper surface of the fan blade 14; the support mechanism includes a strip plate 2, which is fixed in the middle of the duct 1, and a rotating rod 22 is movably passed through the middle of the strip plate 2; the dustproof mechanism includes a filter screen 32, which is set at the port of the duct 1; the connecting mechanism includes a hollow block 4, which is set on the lower side of the middle of the strip plate 2, and the top of the hollow block 4 is fixedly connected to the bottom of the rotating rod 22.
[0026] First, the cleaning structure can be rotatably supported by a support mechanism, and then connected to the rotating power fan blades by a connecting mechanism, which can realize automatic dust removal, replacing disassembly and cleaning, making cleaning more convenient.
[0027] Specifically, the rotating rod 22 is rotatably connected to the strip plate 2 via the bearing 23. A brush 21 is fixedly installed at the top of the rotating rod 22, and the brush of the brush 21 abuts against the filter hole of the filter screen 32. An electric slip ring 25 is sleeved at the bottom of the rotating rod 22, and the electric slip ring 25 is fixedly connected to the strip plate 2 via a crank. A rotor 24 is integrally formed and movably installed on the inner side of the electric slip ring 25, and the rotor 24 is fixedly connected to the rotating rod 22. Inner rods 43 are movably inserted through both sides of the bottom wall of the hollow block 4. A support block 41 is fixedly installed at the top of the inner rod 43, and a spring 42 is sleeved on the outer side of the inner rod 43. Electromagnets 44 are fixedly installed at the bottom of the two sets of inner rods 43, and the electromagnets 44 are located directly above the iron block 13.

[0028] When the filter screen 32 needs to be cleaned during the use of the ventilation device, the electromagnet 44 can be turned on. The electromagnet 44 generates magnetic force and attracts the iron block 13. The slip ring 25 provides power, and the rotating rod 22 and the fan blade 14 rotate synchronously. The rotating rod 22 can drive the brush 21 to clean the filter screen 32.

A wire hole 54 is opened at the bottom inside the box 5.
[0032] The running time and interval of the electromagnet 44 can be set by the time control switch 51, so that the electromagnet 44 can be turned on and off for a certain period of time at a timed interval, which can realize the intermittent cleaning of the filter by the brush 21. The degree of automation is high, and no personnel need to approach to turn the electromagnet 44 on and off. At the same time, the setting of the operation port 53 can adjust the operating frequency of the electromagnet 44 according to the changes in the amount of dust in the surrounding environment in different seasons, which is highly versatile.
