Description

A ventilation device for an elevator car

Technical Field

The utility model relates to the technical field of ventilation devices, and more specifically, to a ventilation device for an elevator car.

Background technique

The elevator car is a box-shaped space used to carry and transport people and materials. Due to the different uses of various types of elevators, their car structures are also different. Elevator cars are also divided into passenger elevator cars, residential elevator cars, freight elevator cars, etc.

Elevators are particularly important for high-rise buildings, as they facilitate people to go up and down floors quickly. Due to the small space in the elevator car, large flow of people, and poor air circulation, the air quality inside the car is poor. In order to ensure air circulation inside the elevator, it is necessary to install a ventilation device to inject fresh air into the car. The ventilation device of the existing elevator car has an air inlet located outside the elevator car. After inhaling air for a long time, a large amount of dust will adhere to the filter screen of the air inlet, resulting in poor ventilation effect. Since the air inlet is outside the elevator car, when the operator cleans the filter screen of the air inlet, he needs to go to the top of the car to clean it, which is very troublesome and has certain safety hazards. Therefore, it needs to be improved.

The working principle and use process of this utility model:

When the operator needs to clean the dust on the outer surface of the filter plate 4, the second motor 15 can be started to rotate the winding roller 16, so that the winding rope 13 is wound around the outer surface of the winding roller 16, so that the winding rope 13 can drive the filter plate 4 to move to the left, and then the first motor 6 is started to make the rotating shaft 7 drive the first gear 8 to rotate. Since the outer surface of the first gear 8 and the outer surface of the second gear 10 are meshed with each other, the first gear 8 drives the second gear 10 and the circular shaft 9 to rotate, so that the two cleaning brushes 11 rotate. When the filter plate 4 moves to the left and passes between the cleaning brushes 11, the cleaning brushes 11 will clean the upper and lower surfaces of the filter plate 4, so that the operator can clean the filter plate 4 without entering the top of the car body 1, and at the same time, it can prevent the cleaned dust from falling into the inside of the fan 17 through the air inlet pipe 18. The operator can start the second motor 15 to reverse the winding roller 16. At this time, the spring 12 will drive the filter plate 4 to reset under the action of elastic recovery.

The operator starts the fan 17 so that the air inlet pipe 18 can suck in air and blow it out through the fixed pipe 19, thereby ventilating the interior of the car body 1. Due to the design of the fixed box 20, when the car body 1 shakes, the dust on the surface of the filter 22 will not fall directly into the interior of the car body 1, thereby preventing dust from falling on the passengers. At the same time, it can prevent the wind blown out of the fixed pipe 19 from blowing directly onto the passengers. When the operator needs to take out the filter 22, the handle 24 can be rotated to make the movable shaft 23 drive the rotating block 25 to rotate, so that the rotating block 25 is disengaged from the interior of the block 26, thereby releasing the fixing effect on the filter 22, and then the handle 24 can be pulled downward so that the handle 24 drives the filter 22 to move downward through the movable shaft 23, thereby removing the filter 22 from the interior of the fixed box 20.
