[0002] Nowadays, elevators can be seen everywhere in residential buildings, office buildings, shopping malls and other places. As a relatively sealed space, ensuring ventilation is one of the basic requirements of elevator design. When the ventilation device is working, it supplies air into the elevator car without exhausting air to achieve the ventilation effect. When the elevator car door is closed, this direct current downward blowing ventilation form makes the air circulation in the elevator car slow, and the ventilation effect is not ideal.

[0003] Publication (Announcement) No.: CN220453852U provides a ventilation device for an elevator, which can provide a better ventilation effect in the elevator car when the elevator car door is closed.

[0004] However, the above patent is inconvenient to replace the filter structure that needs to be replaced regularly after long-term use, which increases the trouble of manual operation and affects the efficiency of use. Utility Model Content

[0008] A dust filter is fixedly connected to the front of the air inlet housing, a feed trough is provided on the upper part of the air inlet housing, a discharge trough is provided on the side of the air inlet housing, and a filter device frame is slidably provided on the feed trough;

[0009] A material preparation casing is fixedly connected to the inner wall of the elevator car, and a material preparation chute is provided on the material preparation casing. The filtering equipment frame can be slidably arranged on the material preparation chute, and the material preparation chute is vertically corresponding to the feed chute. A demoulding pin is inserted into the upper part of the material preparation casing.

[0010] Furthermore, the infrared sensor is electrically connected to a controller, and the controller is electrically connected to the exhaust fan.

[0011] Furthermore, an activated carbon filter plate is fixedly connected inside the filter device frame, and sealing films are pasted on both sides of the activated carbon filter plate.

[0012] The beneficial effects achieved by the utility model using the above structure are as follows:

[0013] 1. By setting up a material preparation structure, after the filter equipment in the air inlet structure is disassembled, it can be quickly replaced to improve the use efficiency;

[0014] 2. During the replacement process, the surface membrane of the filter structure is automatically torn off, and it can be used immediately after being torn off, which can extend the service life of the filter structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a ventilation device for an elevator, comprising an elevator car 1, an exhaust device shell 2 passing through the upper part of the elevator car 1, an exhaust fan 3 passing through the exhaust device shell 2, an infrared sensor 4 fixedly connected to the lower end of the exhaust device shell 2, a controller 5 fixedly connected to the lower end of the exhaust device shell 2, and also comprising an air inlet shell 6 arranged through the side wall of the elevator car 1;

[0021] A dust filter 7 is fixedly connected to the front of the air inlet casing 6 , a feed chute 8 is provided on the upper part of the air inlet casing 6 , a discharge chute 9 is provided on the side of the air inlet casing 6 , and a filter device frame 10 is slidably provided on the feed chute 8 .

[0022] The infrared sensor 4 is electrically connected to the controller 5 , and the controller 5 is electrically connected to the exhaust fan 3 .

[0023] An activated carbon filter plate 11 is fixedly connected inside the filtering device frame 10 , and sealing films are pasted on both sides of the activated carbon filter plate 11 .

[0024] A material preparation casing 12 is fixedly connected to the inner wall of the elevator car 1, and a material preparation chute 13 is provided on the material preparation casing 12. The filtering equipment frame 10 can be slidably arranged on the material preparation chute 13, and the material preparation chute 13 corresponds vertically to the feed chute 8; a demoulding pin 14 is inserted into the upper part of the material preparation casing 12.

[0025] It should be noted that the preparation chute 13 corresponds vertically to the feed chute 8, and a spare filter device frame 10 can be inserted into the preparation chute 13, and the sealing film on it is fixed by the demoulding pins 14. At this time, the filter device frame 10 in the preparation chute 13 is blocked by the filter device frame 10 in the feed chute 8 below. When replacing the filter component, the filter device frame 10 to be replaced can be pulled out from the discharge chute 9. The filter device frame 10 in the preparation chute 13 loses its support and slides into the feed chute 8 under the action of gravity to complete the replacement. The sealing film is fixed by the demoulding pins 14 and is separated from it during the falling process.

[0026] When in use, after a person enters the elevator car 1, the infrared sensor 4 senses the person, and the control signal is sent through the controller 5 to control the exhaust fan 3 to operate, so that the air inside the elevator car 1 is extracted from the top to discharge the foul air, which can reduce the waste of electric energy when no one is using the equipment;

[0027] The external air enters from the air inlet housing 6, is filtered by the activated carbon filter plate 11, and then passes through the dust filter 7 to enter the elevator car 1;

[0028] The two sets of filter device frames 10 can be replaced and used to facilitate replacement efficiency, reduce the impact of manual disassembly to replace the filter structure on the use of the elevator, and improve maintenance efficiency.

[0029] The above is the entire use process of a ventilation device for elevators.

[0030] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
