Therefore, the following detailed description of the embodiment of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiment of the present application. It should be noted that, in the absence of conflict, the various features in the embodiment of the present application can be combined with each other, and the combined embodiment is still within the protection scope of the present application.
[0018] Elevators are usually equipped with fans for ventilation. However, in actual use, dust will be blown into the elevator car, reducing the air quality in the elevator. The filter plate is easily clogged with dust, making maintenance difficult. To solve the above problems, the embodiment of the present application is provided with a filter plate 40 at the air inlet 140 of the fan 30, and an automatic cleaning component for cleaning dust is provided in front of the filter plate 40 to keep the filter plate 40 from being clogged by dust, thereby increasing the use time and removing dust without stopping the elevator for maintenance, thereby improving the air quality in the elevator.
[0019] like Figure 1 As shown, an embodiment of the present application provides an elevator car dust removal component, including: a box body 10, the box body 10 is fixed on the top of the elevator car, a fan 30 is arranged in the box body 10, the air inlet and the air outlet of the fan 30 are respectively connected to the two sides of the box body 10 to form an air inlet 140 and an air outlet 130 on the box body 10, the air outlet 130 and the ventilating port of the elevator are connected by a pipe, and a filter plate 40 is arranged between the air inlet 140 and the air inlet of the fan 30; an automatic cleaning component is arranged on the filter plate 40, the automatic cleaning component includes a reciprocating component and a cleaning member installed on the reciprocating component, and the reciprocating component drives the cleaning member to clean the filter plate 40 back and forth.
[0020] In order to maintain the working efficiency of the fan 30 and the filter plate 40, the box body 10 is a closed box body 10, and the reciprocating assembly drives the cleaning member to clean the filter plate 40 back and forth. Figure 2 As shown, the automatic cleaning component is arranged on the side of the filter plate 40 opposite to the fan 30, and is used to remove dust on the filter plate 40, thereby extending the service life of the filter plate 40. There is no need to manually remove the dust on the filter plate 40. The fan 30 delivers clean air into the elevator car to improve the air quality.
[0021] For example, Figure 2As shown, the reciprocating assembly includes a reciprocating screw 50 and a slider 520 arranged on the reciprocating screw 50, the reciprocating screw 50 is driven by a motor 510, and a cleaning member is arranged on the side of the slider 520 facing the filter plate 40; the reciprocating assembly also includes a guide block 530, the extension direction of the guide block 530 and the reciprocating screw 50 are consistent, a slide rail is fixedly installed on the guide block 530, which is used to slide the slider 520 on the slide rail for limiting, while reducing sliding friction and ensuring that the slider 520 moves along the extension direction of the reciprocating screw 50, the motor 510 drives the reciprocating screw 50 to rotate, and under the guiding effect of the guide block 530, the slider 520 can control the cleaning member to reciprocate on the surface of the filter plate 40, thereby cleaning the dust on the surface of the filter plate 40.
[0022] like Figure 2 As shown, a dust recovery box 150 is arranged below the automatic cleaning component for recovering the dust after cleaning. The dust recovery box 150 is formed by the inner wall of the box body 10. A mounting part is arranged outside the box body 10 for mounting the box body 10 on the top of the elevator car. Below the automatic cleaning component, a dust recovery box 150 for recovering dust is formed by the inner wall of the box body 10. A cavity 110 is formed on the outside of the box body 10 relative to the bottom of the fan 30, which can be used to accommodate lines or wiring to save space.
[0023] like Figure 1 As shown, a revolving door 120 is arranged on the side wall of the dust recovery box 150 away from the automatic cleaning component. The revolving door 120 can be rotated to open and close relative to the box body 10. When the elevator is shut down for maintenance, the dust in the dust recovery box 150 is cleaned at the same time. The revolving door 120 can be opened to open the dust recovery box 150 without disassembling the box body 10, thereby improving the maintenance efficiency. When the revolving door 120 is closed, a sealing strip is affixed to the gap between the revolving door 120 and the box body 10 to keep the box body 10 airtight. Furthermore, a torsion spring is arranged on the connecting hinge between the revolving door 120 and the box body 10, which is used for the revolving door 120 to close on the opening side of the box body 10 in the initial state.
[0024] Specifically, one end of the reciprocating screw 50 extends out of the box body 10, and the motor 510 is connected to the reciprocating screw 50 outside the box body 10 to save space inside the box body 10 and allow the cleaning part to clean a larger area of the filter plate 40. The motor 510 is fixed to the outer wall of the box body 10 through a motor mounting bracket 511.
[0025] In one embodiment of the present application, the cleaning member is a cleaning brush 521 , and the bristles of the cleaning brush 521 are in contact with the surface of the filter plate 40 to remove dust on the surface of the filter plate 40 .
[0026] like Figure 1As shown, the air inlet 140 is provided with an air guide tube 20, one end of the air guide tube 20 extends to the outside of the box body 10, and the other end of the air guide tube 20 extends to the side close to the cleaning member. The setting of the air guide tube 20 can effectively reduce the air inlet space at the air inlet 140, shorten the flow of the airflow in the box body 10, concentrate the airflow with less loss, increase the airflow density, and thus improve the ventilation efficiency.
[0027] When the utility model is in use, the filter plate 40 arranged at the air inlet 140 of the box body 10 can allow the fan 30 to deliver clean air to the elevator car. At the same time, the automatic cleaning component can clean the dust on the filter plate 40, thereby increasing the service life of the filter plate 40. There is no need to manually open the box body 10 to clean the filter plate 40. The cleaned dust can be recovered to the dust recovery box 150. When the elevator is shut down for maintenance, the dust in the dust recovery box 150 can be removed together to improve work efficiency.
[0028] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
