[0014] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0015] See attached diagram. Figures 1 to 3 An environmentally friendly ventilated passenger elevator in this embodiment includes a car 1. A ventilation box 2 is provided on the top of the car 1. The ventilation box 2 includes two sets of side plates 3, a top plate 20, a bottom plate 21, and front and rear end plates. The two sets of side plates 3, the top plate 20, and the front and rear end plates are an integral structure. A flip-plate mechanism is provided on the side plate 3. The output end of the flip-plate mechanism is fixedly connected to the bottom plate 21. The ventilation box 2 is provided with an air intake chamber and an air supply chamber. A filter plate 4 is embedded in the side plate 3 in the air supply chamber. An air supply pipe 40 is provided on one side of the filter plate 4.

[0016] Furthermore, the flip-up mechanism includes a mounting block 5 installed on the inner wall of the side plate 3. The mounting block 5 has a vertical groove 50, and an arc-shaped groove 51 communicating with the vertical groove 50 is provided on one side of the vertical groove 50. The mounting block 5 on the side plate 3 is provided with a drive motor 52. The output end of the drive motor 52 is provided with a first connecting rod 6. A second connecting rod 60 is hinged to the first connecting rod 6. A connecting shaft 61 is hinged to the end of the second connecting rod 60. A first slider is provided at the end of the connecting shaft 61. A Z-shaped rod 7 is hinged to the connecting shaft 61. A second slider 70 is provided on the Z-shaped rod 7. The vertical groove 50 and the arc-shaped groove 51 are both slidably connected to the first slider, and the second slider 70 is slidably connected to the vertical groove 50.

[0017] Furthermore, the bottom of the Z-shaped rod 7 is provided with a connecting piece 800, which is connected to the base plate 21 by bolts.

[0018] Furthermore, the bottom plate 21 is provided with a first partition plate 210 and a second partition plate 211, and the top plate 20 is provided with a first slot 200 and a second slot 201. The first partition plate 210 and the second partition plate 211 are respectively engaged with the first slot 200 and the second slot 201. The first partition plate 210 and the second partition plate 211 divide the ventilation box 2 into an air intake chamber and an air supply chamber. The side plate 3 in the air intake chamber is provided with an air intake pipe 30, the top plate 20 in the air intake chamber is provided with an exhaust pipe 22, and the top plate 20 in the air supply chamber is provided with an air inlet pipe 23.

[0019] Furthermore, both the first partition plate 210 and the second partition plate 211 are equipped with a fan 8, and the output end of the fan 8 is equipped with a fan blade 80.

[0020] Working principle: The first partition plate 210 and the second partition plate 211 in the ventilation box 2 divide the ventilation box 2 into an air intake chamber and an air supply chamber in an orderly manner, so that the air intake and air supply processes are independent of each other and avoid air mixing. The air intake chamber draws in the air in the car 1 through the air intake pipe 30 and discharges it through the exhaust pipe 22. The air supply chamber introduces external air through the air inlet pipe 23 and sends it into the car 1 through the air supply pipe 40. The introduced air is filtered by the filter plate 4 to ensure that the air in the car is fresh.

[0021] When it is necessary to inspect and replace the filter disc 4 in the ventilation box 2, the drive motor 52 is started. The drive motor 52 drives the first connecting rod 6 to rotate, which in turn drives the second connecting rod 60 to move. Since the end of the second connecting rod 60 is hinged to the connecting shaft 61 and the end of the connecting shaft 61 is slidably connected to the vertical groove 50, the connecting shaft 61 and the Z-shaped rod 7 move downward first, which in turn causes the bottom plate 21 to move downward and separate from the ventilation box 2. When the first slider on the connecting shaft 61 slides into the arc groove 51, the first connecting rod 6 and the second connecting rod 60 rotate, and at the same time, the Z-shaped rod 7 and the connecting shaft 61 also rotate, which causes the bottom plate to rotate. At this time, the first partition plate 210 and the second partition plate 211 are respectively dislodged from the first slot 200 and the second slot 201. Then the fan 8 can be inspected and the filter disc 4 can be replaced.

[0022] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
