[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-6An elevator ventilation device includes a housing 1, a base plate 2 horizontally mounted at the bottom of the housing 1, a dustproof plate 5 horizontally mounted at the top of the housing 1, a odor dispersing box 3 fixedly connected to the bottom surface of the base plate 2, a mounting bracket 22 vertically mounted on the side wall of the base plate 2 and on one side of the odor dispersing box 3, a limiting mechanism 4 vertically mounted on the mounting bracket 22, a cavity opened inside the odor dispersing box 3, a placement opening 31 communicating with the internal cavity opened on one side wall of the odor dispersing box 3, and odor dispersing openings 32 opened at the top and bottom of the odor dispersing box 3. The placement opening 31 is used to place existing fragrance bags into the cavity of the odor dispersing box 3.

[0023] In addition, the housing 1 has an installation cavity 15 inside, and a first ventilation port 13 communicating with the installation cavity 15 is opened on the top of the housing 1. Multiple installation columns 14 are evenly arranged on the top wall of the installation cavity 15 and outside the first ventilation port 13. The installation columns 14 are used to install the fan assembly 6, and the first ventilation port 13 is used for air to enter.

[0024] Furthermore, multiple mounting feet 12 are symmetrically arranged on the side walls of both sides of the housing 1, and a limiting plate 11 is provided on the top surface of the housing 1 outside the first ventilation opening 13. The limiting plate 11 is used for horizontal insertion and installation of the dustproof plate 5, and the mounting feet 12 are used for installing the housing 1 onto the elevator.

[0025] The dustproof panel 5 is equipped with a dustproof net 51, which covers the first ventilation opening 13. The dustproof net 51 is used to prevent dust from flowing into the elevator.

[0026] Meanwhile, a second ventilation opening 21 is provided on the base plate 2. The second ventilation opening 21 is located below the fan assembly 6 and is used for ventilation.

[0027] Furthermore, the limiting mechanism 4 includes telescopic connecting rods 41 symmetrically arranged on the mounting frame 22. The top end of the telescopic connecting rod 41 is connected to the mounting frame 22, and the bottom telescopic rod of the telescopic connecting rod 41 is connected to a baffle 43. The baffle 43 is used to block the placement opening 31. Springs 42 are sleeved on the outside of the telescopic connecting rod 41. The top end of the spring 42 is connected to the mounting frame 22, and the bottom end is connected to the baffle 43. The baffle 43 is used to block the placement opening 31.

[0028] In this embodiment, when the fan assembly 6 ventilates the inside of the elevator, a fresh air fragrance sachet can be placed in the odor dispersing box 3. When placing the fragrance sachet into the odor dispersing box 3, the baffle 43 is pressed down first, causing the telescopic connecting rod 41 to retract. The bottom of the telescopic connecting rod 41 retracts into the top of the rod, and the spring 42 is simultaneously compressed and retracted, causing the baffle 43 to move upward and no longer block the placement opening 31. The operator can then place the fragrance sachet into the odor dispersing box 3. After placement, the baffle 43 is released, and the spring 42 releases its elastic potential energy, causing the telescopic connecting rod 41 to extend, which in turn causes the baffle 43 to reset and block the placement opening 31 again.

[0029] When the fan assembly 6 is ventilating, the airflow passes through the second vent 21 and diffuses the fragrance of the fragrance bag into the elevator through the odor vent 32, thereby freshening the air, creating a comfortable environment inside the elevator, and preventing odorous air from entering the elevator shaft and affecting the environment inside the elevator.

[0030] The dustproof plate 5, which is horizontally inserted at the limiting plate 11, can effectively prevent dust from falling into the mounting cavity 15 from the first vent 13.

[0031] In this invention, when the elevator is ventilated by the ventilation device, the fragrance of the fragrance bag in the fragrance box 3 is released into the elevator through the odor vent 32, thereby freshening the air, creating a comfortable environment inside the elevator, preventing the air with odors in the elevator shaft from entering the elevator and affecting the environment inside the elevator, and effectively creating a comfortable elevator riding environment.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
