[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-4 The utility model provides a technical solution: a ventilation device applied to an elevator, comprising:

[0031] The car 1 has a plurality of first air outlets 2 at the bottom of the side of the car 1, and a first air inlet 3 is arranged at the top of the car 1. The first air outlets 2 are connected to the first air inlet 3 through pipes 4. The pipes are built into the car, which is more beautiful.

[0032] A partition assembly, comprising a first partition 5 and a second partition 6 arranged above the first partition 5, an air duct 7 is arranged between the first partition 5 and the second partition 6, a second air outlet 8 is arranged on the first partition 5, and a third air outlet 9 is arranged on the second partition 6;

[0033] A fan 10, wherein the fan 10 is disposed on the second partition plate 6, the second air inlet 11 of the fan 10 is connected to the first air inlet 3, and the air outlet 12 of the fan 10 is connected to the third air outlet 9;

[0034] The filter component 13 is located between the first air inlet 3 and the fan 10 .

[0035] The second air outlet 8 is staggered with the third air outlet 9. Specifically, the second air outlet is staggered with the third air outlet in height and horizontal direction to prevent the fan noise from directly propagating to the second air outlet of the first partition and radiating into the interior of the car, thereby achieving the purpose of noise reduction.

[0036] The filter component 13 includes a mounting frame 131 and a first filter layer 132, a second filter layer 133 and an activated carbon filter layer 134 arranged in the mounting frame 131, wherein the activated carbon filter layer 134 is located between the first filter layer 132 and the second filter layer 133. The first filter layer 132 is a metal filter. The second filter layer 133 is a filter cloth or a HEPA filter. The outside air flowing into the mounting frame will enter the fan after passing through the metal filter, the activated carbon filter layer and the HEPA filter, and finally enter the elevator car, thereby effectively filtering out fine particle pollutants and harmful substances such as formaldehyde in the outside air, making the air flowing into the elevator car fresher.

[0037] The first air outlet 2 is provided with a metal filter screen, which can filter the air entering the pipeline. In order to improve the efficiency of the air entering the pipeline, an exhaust fan can be installed on the pipeline.

[0038] Working principle: By arranging multiple first air outlets at the bottom of the side of the car, when the door is closed, the fan draws air, and the air outside the car enters from the first air inlet. After being filtered by the filter component, the air passes through the fan, the third air outlet and the second air outlet in sequence and enters the car. The wind flows downward from the top of the car. At the same time, the air at the bottom of the car enters the pipe through the first air inlet, is discharged into the first air inlet, filtered by the filter component, and then enters the car again, realizing air circulation inside the car, improving ventilation effect and improving air quality.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
