DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Reference Figure 1-5 A ventilation mechanism for an elevator car comprises a main body 1, two Z-shaped ventilation pipes 2 are fixedly connected to the top of the main body 1, a filter frame 4 is provided at one end of the ventilation pipe 2 located inside the main body 1 through a mounting mechanism 3, specifically, the mounting mechanism 3 facilitates the removal of the filter frame 4 when cleaning is required, two guide plates 5 are fixedly connected inside the ventilation pipe 2, two support rods 6 are fixedly connected to the inner bottom of the main body 1, a hanging plate 7 is fixedly connected to the bottom of the support rods 6, two air ducts 8 are fixedly connected to the bottom of the main body 1, arc-shaped guide cavities 9 are opened inside both sides of the main body 1, and the air ducts 8 are connected to the guide cavities 9.

[0025] This program has the following working process:

[0026] During the use of the elevator, ventilation is required to ensure air circulation inside the elevator. During the rising process of the main body 1, the air can enter the main body 1 through the ventilation pipe above. Before the air enters the main body 1, it needs to be filtered by the filter frame 4 to prevent debris from entering. The air can be conveniently guided by the guide plate 5 inside the ventilation pipe 2, so that the air can conveniently enter the main body 1 during the rising process of the main body 1. The hanging plate 7 fixed by the support rod 6 prevents fine dust from falling directly from above onto the heads of the passengers. When the main body 1 descends, the air enters the guide cavity 9 through the air pipe 8, and then enters the main body 1, so that the upper and lower parts of the main body 1 can be ventilated. When used for a long time, the filter frame 4 can be replaced through the installation mechanism 3 to ensure smooth ventilation.

[0027] According to the above working process, we can know that:

[0028] When the elevator is running, the elevator car body 1 needs to be ventilated to ensure that the air inside the body 1 flows smoothly without causing a stuffy feeling, making it convenient for passengers to use the elevator. During ventilation, the air will not blow directly at the passengers, making the passengers comfortable.

[0029] Furthermore, the mounting mechanism 3 includes two mounting grooves 301 opened at the bottom of the ventilation pipe 2, and a mounting rod 302 is penetrated through the surface of the filter frame 4, and the mounting rod 302 is penetrated through the inside of the mounting groove 301. Specifically, when the filter frame 4 needs to be installed, the mounting rod 302 is first pulled out of the filter frame 4, and then after the filter frame 4 is moved to the bottom of the ventilation pipe 2, the mounting rod 302 can be moved so that the mounting rod 302 passes through the filter frame 4 and the mounting groove 301 at the same time, so that the filter frame 4 is fixed on the ventilation pipe 2.

[0030] Furthermore, the cross-section of the mounting rod 302 is T-shaped, and the mounting rod 302 is elastically connected to the surface of the filter frame 4 through the compression spring 303. Specifically, when the filter frame 4 is fixed by the mounting rod 302, the compression spring 303 can prevent the mounting rod 302 from being easily separated from the filter frame 4, so that after the filter frame 4 is fixed, it can be relatively stable and will not easily fall off the ventilation pipe 2.

[0031] Furthermore, a leakage groove 10 is provided on the surface of the hanging plate 7, and a plurality of shielding blocks 11 are fixedly connected to the top of the hanging plate 7. Specifically, the leakage groove 10 can make it more convenient for air to enter without being blocked by the hanging plate 7 to affect the ventilation effect, and the shielding blocks 11 can also block and collect dust falling from the filter frame 4 to prevent dust from leaving from the edge of the hanging plate 7.

[0032] Furthermore, two L-shaped cards 12 are fixedly connected to the side of the guide chamber 9, and a filter plate 13 is slidably connected to the inside of the guide chamber 9. Specifically, during the operation of the guide chamber 9, the filter plate 13 can prevent debris from entering and affecting ventilation, so the filter plate 13 is clamped in the guide chamber 9 by the card 12 for filtering.

[0033] Furthermore, a slide groove 14 is provided at the top and bottom of the filter plate 13, and the interior of the slide groove 14 is elastically connected to a card plate 16 through an extrusion spring 15, and the card plate 16 is fitted with the card 12. Specifically, when installing the filter plate 13, the card plate 16 can be squeezed, and then the filter plate 13 can be placed in the guide cavity 9, and then the card plate 16 can be released. The card plate 16 is moved to the card 12 by the elastic force of the extrusion spring 15, so that the filter plate 13 is stuck in the guide cavity 9.

[0034] To sum up, when the elevator car body 1 is in use, the body 1 can be conveniently ventilated through the ventilation pipe 2 and the air duct 8, and then the air will not be blown directly onto the occupants through the hanging plate 7 and the guide cavity 9. During ventilation, ventilation can be carried out by relying on the up and down movement of the body 1.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
