Description

Technical Field

[0001] This utility model relates to the field of ventilation device technology, and in particular to an elevator ventilation device. Background Technology

[0002] Elevators are an indispensable piece of equipment in modern high-rise buildings. With economic development and the continuous improvement of people's living standards, competition in elevator technology is becoming increasingly fierce, and people's requirements for riding elevators are also getting higher and higher. The elevator car is a box-like structure used for riding. People enter the car and the motor drives the car to rise and fall, thereby realizing the function of transportation. Because the car is a relatively sealed elevator box structure and there are many people riding in it, ventilation is required to ensure that passengers can breathe smoothly.

[0003] Existing elevator ventilation systems are typically installed at the top of the elevator and ventilate the elevator by supplying filtered air. During air supply, filters are used to remove dust and prevent contamination. However, elevator usage decreases significantly at night compared to daytime, leaving the filters exposed to the air. This allows dust to accumulate on the filters, clogging their surface and hindering their ability to filter air. Consequently, the ventilation effect inside the elevator is compromised, necessitating improvements. Utility Model Content

[0056] Reference Figures 1 to 6 The present invention provides a further description of an embodiment of an elevator ventilation device.

[0057] An elevator ventilation device includes a support frame 1 and a support groove 2, the support groove 2 being formed on the support frame 1; it also includes: multiple support columns 3, which are evenly arranged on the support frame 1 and fixedly connected to the support frame 1; a support plate 4, which is disposed on the support columns 3 and fixedly connected to the support columns 3; a fan 5, which is disposed on the support frame 1 and fixedly connected to the support frame 1; a filter frame 6, which is disposed in the support groove 2 and slidably connected to the support groove 2; a filter plate 7, which is fixedly connected to the filter frame 6; a clamping mechanism disposed on the support frame 1 for clamping and fixing the filter frame 6; and an opening and closing mechanism disposed on the support frame 1 for opening and closing the filter plate 7 to prevent dust accumulation on the filter plate 7 when the elevator is not in use.

[0058] Reference Figure 5 and Figure 6 In a preferred embodiment, the clamping mechanism includes: a clamping groove 8 formed on the support frame 1; a clamping post 9 disposed in the clamping groove 8 and fixedly connected to the support frame 1; a clamping block 10 disposed in the clamping groove 8 and slidably connected to the clamping post 9; a clamping shaft 11 fixedly connected to the clamping block 10; a clamping sleeve 12 fixedly connected to the clamping shaft 11; a clamping spring 13, one end of which is fixedly connected to the clamping block 10 and the other end of which is fixedly connected to the support frame 1; and a sliding component disposed in the clamping groove 8.

[0059] During operation, pulling the clamping sleeve 12 causes the clamping shaft 11, which is fixedly connected to the clamping sleeve 12, to move away from each other, causing the clamping block 10, which is fixedly connected to the clamping shaft 11, to slide on the clamping rod in the clamping groove 8, causing the clamping blocks 10 to move away from each other, thereby compressing the clamping spring 13 and generating elastic potential energy.

[0060] Reference Figure 5 and Figure 6 In a preferred embodiment, the sliding component includes: a sliding block 14, which is disposed on the clamping block 10 and fixedly connected to the clamping block 10; a sliding column 15, which is disposed on the sliding block 14 and fixedly connected to the sliding block 14; and a rectangular block 16, which is fixedly disposed on the filter frame 6, and is slidably connected to the clamping groove 8 and to the sliding column 15.

[0061] During operation, the sliding block 14, which is fixedly connected to the clamping block 10, slides in the clamping groove 8, causing the sliding column 15 to move. The sliding column 15 moves outward from the rectangular block 16 until the sliding column 15 is completely detached from the rectangular block 16. Then, the filter frame 6 is removed, and the new filter plate 7 is placed in the support groove 2, so that the rectangular block 16 is placed in the clamping groove 8. Then, the clamping sleeve 12 is released, so that the clamping spring 13 releases its elastic potential energy, causing the clamping blocks 10 to move closer to each other, causing the sliding column 15 to slide inward from the rectangular block 16 until the sliding columns 15 contact each other.

[0062] Reference Figure 4 In a preferred embodiment, the opening and closing mechanism includes: an opening and closing block 17, which is disposed on the support frame 1 and fixedly connected to the support frame 1; an opening and closing frame 18, which is fixedly connected to the opening and closing block 17; an opening and closing motor 19, which is disposed inside the opening and closing frame 18 and fixedly connected to the opening and closing frame 18; an opening and closing shaft 20, which is fixedly connected to the output end of the opening and closing motor 19 and rotatably connected to the opening and closing block 17; and a rotating component, which is disposed on the opening and closing block 17.

[0063] When in operation, the opening and closing motor 19 is started, which drives the opening and closing shaft 20, which is fixedly connected to the output end of the opening and closing motor 19, to rotate on the opening and closing block 17.

[0064] Reference Figure 4 In a preferred embodiment, the rotating component includes: a rotating groove 21 formed on the opening and closing block 17; two rotating blocks 22, which are symmetrically arranged in the rotating groove 21, slidably connected to the rotating groove 21, and threadedly connected to the opening and closing shaft 20; a rotating frame 23, which is disposed on the rotating block 22 and fixedly connected to the rotating block 22; and a transmission component disposed on the support frame 1.

[0065] During operation, the rotating block 22, which is threadedly connected to the opening and closing shaft 20, rotates, causing the rotating block 22 to slide in the rotating groove 21, so that the rotating blocks 22 move closer to each other, thereby causing the rotating frame 23 to move.

[0066] Reference Figure 4 In a preferred embodiment, the transmission component includes: a transmission plate 24, which is disposed on the support frame 1 and fixedly connected to the support frame 1; a transmission groove 25, which is formed on the transmission plate 24; and two transmission blocks 26, which are symmetrically arranged in the transmission groove 25 and slidably connected to the transmission groove 25.

[0067] During operation, the transmission blocks 26, which are fixedly connected to the rotating frame 23, slide within the transmission groove 25, causing the transmission blocks 26 to move closer to each other until the rotating frame 23 comes into contact with each other.

[0068] Working principle: When the elevator operates at a low frequency, the opening and closing motor 19 is started, which drives the opening and closing shaft 20, which is fixedly connected to the output end of the opening and closing motor 19, to rotate on the opening and closing block 17. This causes the rotating block 22, which is threadedly connected to the opening and closing shaft 20, to rotate. The rotating block 22 slides in the rotating groove 21, causing the rotating blocks 22 to move closer to each other. This causes the rotating frame 23 to move, causing the transmission block 26, which is fixedly connected to the rotating frame 23, to slide in the transmission groove 25. This causes the transmission blocks 26 to move closer to each other until the rotating frame 23 contacts each other. This achieves the purpose of shielding the filter plate 7, preventing excessive dust accumulation on the filter plate 7 and affecting its performance.

[0069] Then, when the filter plate 7 needs to be replaced, first pull the clamping sleeve 12, causing the clamping shaft 11 fixedly connected to the clamping sleeve 12 to move away from each other, so that the clamping block 10 fixedly connected to the clamping shaft 11 slides on the clamping rod in the clamping groove 8, causing the clamping blocks 10 to move away from each other, thereby compressing the clamping spring 13 and generating elastic potential energy, causing the sliding block 14 fixedly connected to the clamping block 10 to slide in the clamping groove 8, causing the sliding column 15 to move, so that the sliding column 15 moves to the outside of the rectangular block 16 until the sliding column 15 is completely separated from the rectangular block 16. Then, take out the filter frame 6, and place the new filter plate 7 into the support groove 2, so that the rectangular block 16 is placed into the clamping groove 8. Then, release the clamping sleeve 12, so that the clamping spring 13 releases elastic potential energy, causing the clamping blocks 10 to move closer to each other, causing the sliding column 15 to slide into the rectangular block 16 until the sliding column 15 contacts each other, thereby realizing the replacement of the filter plate 7.

[0070] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
