All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0021] Combined with Figures 1 - 2 , a dust-proof structure for an elevator controller chassis includes a main box body 1, a box door 11 is hinged on one side of the main box body 1, a ventilation slot 12 is opened on one side of the main box body 1, a controller main body 2 is arranged inside the main box body 1, a partition board is fixedly connected to the inner wall of the main box body 1, an air extractor 5 is arranged inside the partition board, an electric telescopic rod 3 is fixedly connected to the inner wall of the main box body 1, and a dust removal mechanism 4 for removing dust is arranged at the bottom end of the electric telescopic rod 3.

[0022] The present invention will be further described below in conjunction with the embodiments.

[0023] Combined with Figures 2 - 4 , the dust removal mechanism 4 includes an ash removal plate 41 fixedly connected to the bottom end of the electric telescopic rod 3. A top plate 14 is fixedly connected between the main box body 1 and the partition board. The ash removal plate 41 is arranged below the top plate 14. An activity slot 411 is opened on one side of the ash removal plate 41. There are two groups of the activity slots 411, and the two groups of the activity slots 411 are symmetrically arranged. A spring rod 42 is fixedly connected to the inner wall of the activity slot 411. One end of the spring rod 42 is fixedly connected to an activity block 43. A rotating rod 44 is rotatably connected between the two groups of the activity blocks 43. A cleaning cotton 45 is fixedly connected to the outer side of the rotating rod 44. The cleaning cotton 45 is attached to one side of the partition board. When removing dust, the electric telescopic rod 3 is turned on. The electric telescopic rod 3 drives the ash removal plate 41 to move downward, and then drives the cleaning cotton 45 to move downward to clean one side of the partition board. The spring rod 42 drives the activity block 43 to make the cleaning cotton 45 always fit the partition board. At the same time, the rotating rod 44 rotates to promote the cleaning effect.

[0024] A filter screen 51 is fixedly connected to one side of the partition board inside the main box body 1. The filter screen 51 is correspondingly arranged with the air extractor 5 and the cleaning cotton 45 is attached to the filter screen 51. Through the setting of the filter screen 51, it plays a role in blocking dust during the air extraction process.

[0025] A gas storage pipe 46 is fixedly connected to the bottom surface of the dust removal plate 41. A support plate 47 is fixedly connected to the bottom surface of the inner wall of the main box body 1. One end of the support plate 47 is fixedly connected to a sealing plate 471. The sealing plate 471 is slidably connected to the inside of the gas storage pipe 46. A one-way pressure valve A461 is fixedly connected to one side of the gas storage pipe 46. The one-way pressure valve A461 is arranged corresponding to the air permeation groove 12. During the downward movement of the dust removal plate 41, the support plate 47 cooperates with the sealing plate 471 to squeeze the air inside the gas storage pipe 46, and the air is discharged through the one-way pressure valve A461 to inflate the air permeation groove 12, thereby removing the dust remaining inside the air permeation groove 12.

[0026] A one-way pressure valve B462 is fixedly connected to one side of the gas storage pipe 46. Through the setting of the one-way pressure valve B462, during the upward movement of the dust removal plate 41, air is supplemented into the inside of the gas storage pipe 46 through the one-way pressure valve B462 to balance the air pressure.

[0027] A sealing ring 472 is fixedly connected to the outside of the sealing plate 471. The outside of the sealing ring 472 is attached to the inner wall of the gas storage pipe 46. Through the setting of the sealing ring 472, the sealing effect of the sealing plate 471 is enhanced.

[0028] A dust baffle 13 is fixedly connected to the outside of the main box body 1. The dust baffle 13 is arranged corresponding to the air permeation groove 12. Through the setting of the dust baffle 13, a dust blocking effect is achieved on the air permeation groove 12.

[0029] Specifically, during dust removal, the electric telescopic rod 3 is turned on. The electric telescopic rod 3 drives the dust removal plate 41 to move downward, and further drives the cleaning cotton 45 to move downward to clean one side of the partition board. The spring rod 42 drives the movable block 43 to make the cleaning cotton 45 always fit the partition board. At the same time, the rotating rod 44 rotates to promote the cleaning effect. At the same time, during the downward movement of the dust removal plate 41, the support plate 47 cooperates with the sealing plate 471 to squeeze the air inside the gas storage pipe 46, and the air is discharged through the one-way pressure valve A461 to inflate the air permeation groove 12, thereby removing the dust remaining inside the air permeation groove 12. Finally, the purpose of preventing dust accumulation inside the chassis and facilitating dust removal is achieved.
