Technical Field
[0001] The utility model belongs to the technical field of elevator cars, and specifically relates to a ventilation device for an elevator car. Background Art
[0002] In today's high-rise buildings, elevators are widely used as the main vertical transportation tool, and the ventilation conditions in the elevator car directly affect the comfort and health of passengers. With the continuous improvement of people's quality of life and the higher pursuit of health and comfortable environment, the performance of elevator car ventilation devices has become crucial.
[0003] In the traditional elevator car ventilation design, there are often a series of problems that are difficult to ignore. Common ventilation devices usually only open simple vents at specific locations in the car and are equipped with fixed filters to filter the outside air. However, this design has many limitations.
[0004] First, during long-term use, the fixed filter will inevitably intercept dust, particles and other impurities in the air, and its filter surface will gradually become blocked. As the degree of blockage increases, the ventilation volume will be significantly reduced, causing the air circulation in the car to become extremely poor. This will not only make passengers feel stuffy and depressed in the car, but staying in this environment for a long time may also affect the physical and mental health of passengers.
[0005] Secondly, in order to maintain good ventilation, the traditional solution is to rely on manual regular replacement of the filter. However, this method not only consumes a lot of manpower and time, but also the operation process is cumbersome and complicated. In addition, the frequency of manual replacement of the filter is often difficult to accurately grasp, which may result in the filter being replaced when it is already seriously clogged, thus affecting the ventilation effect for a considerable period of time.
[0006] Furthermore, due to the different operating environments and usage frequencies of elevators, the filter screen will clog at different speeds, which makes it very difficult to formulate a unified schedule for manual filter screen replacement, and it is easy to replace the filter screen in a delayed manner or replace it too much, the former affecting the ventilation quality and the latter causing a waste of resources.
[0007] To this end, we have proposed an elevator car ventilation device, which not only does not require frequent replacement of filters by manpower, thus saving time and effort, but also avoids the problem of reduced ventilation effect due to filter blockage through the design of a flexible filter with a replaceable filter surface, thereby maintaining efficient ventilation at all times. Utility Model Content
[0008] The purpose of this utility model is to provide an elevator car ventilation device. This device not only eliminates the need for frequent manual replacement of the filter screen, achieving the effect of saving time and effort, but also, through the design of a flexible filter screen with a replaceable filter surface, can avoid the problem of reduced ventilation effect caused by filter screen blockage and always maintain efficient ventilation and air exchange.
[0009] The technical solution adopted by this utility model is specifically as follows:

A rectangular shell is provided at the position of the ventilation hole. Two sliding grooves and a through groove communicating with the ventilation hole are opened on the rectangular shell. The through groove communicates with the two sliding grooves, and a ventilation component is provided inside the through groove. Hollow guide plates communicating with the sliding grooves are provided on both sides of the rectangular shell.
[0011] Hollow shells are provided at the tops of the two support plates. A hollow guide plate communicating with the cavity inside each hollow shell is provided on one side of each hollow shell. A rotating component is provided on each hollow shell. A winding roller located inside the hollow shell is provided on the rotating component. A flexible filter screen is provided between the two winding rollers. The flexible filter screen is movably arranged inside the two hollow guide plates, the two sliding grooves, and the through groove.
[0012] Further, the ventilation component includes a first bracket provided on the inner wall of the rectangular shell. A first motor is provided on the first bracket. A fan blade is installed at the output end of the first motor.
[0013] Further, the rotating component includes a second bracket provided on the hollow shell. A stepping motor is provided on the second bracket. A rotating shaft is installed at the output end of the stepping motor. The end of the rotating shaft away from the stepping motor penetrates through the hollow shell and is connected to the winding roller.
[0014] Further, a cleaning roller fitting the winding roller is rotatably arranged inside the hollow shell. A rotating rod is provided on the cleaning roller. The end of the rotating rod away from the cleaning roller penetrates through the hollow shell and is installed with a first gear.

Detailed Description of the Preferred Embodiments
[0026] In order to make the purpose and advantages of the present utility model more clear and understandable, the following specifically describes the present utility model in combination with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection of the specific requests of the present utility model.
[0027] Such as Figures 1-5As shown in the figure, the technical solution adopted by this utility model is as follows: An elevator car ventilation device includes a car body 1. There are two support plates 2 and a ventilation hole 3 arranged at the top of the car body 1. A rectangular shell 4 is arranged at the position of the ventilation hole 3. Two sliding grooves 5 and a through groove 6 communicating with the ventilation hole 3 are opened on the rectangular shell 4. The through groove 6 communicates with the two sliding grooves, and a ventilation component is arranged inside the through groove 6. Both sides of the hollow shell 8 are provided with hollow guide plates 7 communicating with the sliding grooves 5.
[0028] Both tops of the two support plates 2 are provided with hollow shells 8. One side of each hollow shell 8 is provided with a hollow guide plate 7 communicating with its hollow cavity, and a rotating component is arranged on each hollow shell 8. A winding roller 9 located inside the hollow shell 8 is arranged on the rotating component. A flexible filter net 10 is arranged between the two winding rollers 9. The flexible filter net 10 is movably arranged inside the two hollow guide plates 7, the two sliding grooves 5 and the through groove 6.
[0029] Its working principle is as follows: First, the ventilation component provides power, so that the outside air enters the inside of the ventilation hole 3 through the filtration of the flexible filter net 10, and then enters the inside of the car body 1, so that the air in the car body 1 circulates, achieving the effect of ventilation and air change. After a long time of use, the filtering surface of the flexible filter net 10 will be blocked by dust. At this time, the two rotating components are started. One rotating component drives the corresponding winding roller 9 to wind the flexible filter net 10, and the other rotating component drives the corresponding winding to unwind the flexible filter net 10. At this time, the flexible filter net 10 moves inside the hollow guide plate 7 and the sliding groove 5, so as to achieve the effect of replacing the filtering surface of the flexible filter net 10, thereby improving the ventilation effect. This device not only does not require frequent manual replacement of the filter net, achieving the effect of saving time and effort, but also through the design of the flexible filter net 10 with a replaceable filtering surface, it can avoid the problem of the ventilation effect decreasing due to the blockage of the filter net, and always maintain efficient ventilation and air change.
[0030] Among them, the flexible filter net is made of flexible materials, such as high-density polyethylene net, polyester net, etc., and has good dust-proof effects.
[0031] At the same time, the thickness of the flexible filter net 10 matches the thickness of the hollow cavity of the hollow guide plate 7. The meaning of "matching" here is that the flexible filter net 10 can move in the hollow cavity of the hollow guide plate 7 and can prevent air from entering.
[0032] As Figure 5 shown, the ventilation component includes a first bracket arranged on the inner wall of the rectangular shell 4. A first motor 11 is arranged on the first bracket. A fan blade 12 is installed at the output end of the first motor 11. The first motor 11 is fixed by the first bracket, and the fan blade 12 is driven by the first motor 11 to rotate, so as to achieve the effect of making the air circulate.
[0033] The rotating assembly includes a second bracket 13 provided on the hollow housing 8. A stepping motor 14 is provided on the second bracket 13. A rotating shaft is installed at the output end of the stepping motor 14. One end of the rotating shaft away from the stepping motor 14 penetrates through the hollow housing 8 and is connected to the winding roller 9.
[0034] The stepping motor 14 is supported by the second bracket 13. The winding roller 9 is rotated by driving the rotating shaft through the stepping motor 14, so as to wind and unwind the flexible filter net 10.
[0035] An impurity removing roller 16 that fits with the winding roller 9 is rotatably arranged inside the hollow housing 8. A rotating rod is provided on the impurity removing roller 16. One end of the rotating rod away from the impurity removing roller 16 penetrates through the hollow housing 8 and a first gear 17 is installed. A second gear 18 meshing with the first gear 17 is provided on the rotating shaft.
[0036] When the rotating shaft rotates, it drives the second gear 18 to rotate. The second gear 18 drives the first gear 17 to rotate. The first gear 17 drives the rotating rod to make the impurity removing roller 16 rotate, so as to remove the impurities on the flexible filter net 10 on the winding roller 9.
[0037] Wherein, impurity removing brushes are provided on the impurity removing roller 16, and the effect of impurity removal can be further improved through the impurity removing brushes.
[0038] A waste discharging hole is opened at the bottom of the hollow housing 8, and the removed impurities are discharged through the waste discharging hole.
[0039] The working principle of this utility model is as follows: First, power is provided by the ventilation assembly, so that the outside air enters the ventilation holes 3 through the filtration of the flexible filter net 10, and then enters the car body 1, so that the air in the car body 1 circulates, achieving the effect of ventilation and air change. After a long time of use, the filtering surface of the flexible filter net 10 will be blocked by dust. At this time, the two rotating assemblies are started. One rotating assembly drives the corresponding winding roller 9 to wind the flexible filter net 10, and the other rotating assembly drives the corresponding winding to unwind the flexible filter net 10. At this time, the flexible filter net 10 moves inside the hollow guide plate 7 and the sliding groove 5, so as to achieve the effect of replacing the filtering surface of the flexible filter net 10, thereby improving the ventilation effect. The device not only does not require frequent manual replacement of the filter net, achieving the effect of saving time and effort, but also through the design of the flexible filter net 10 with a replaceable filtering surface, it can avoid the problem of the ventilation effect decreasing due to the blockage of the filter net, and always maintain efficient ventilation and air change.
[0040] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
