[0002] Currently in the medical field, it is necessary to recycle various types of waste in the medical process, such as placing syringes after dispensing medicine in the corresponding waste storage area for storage. However, if the medical waste is stored improperly, a large amount of medical waste gas will overflow, thus endangering human health. Utility Model Content

[0003] In order to reduce the overflow of medical waste gas during the storage of medical waste, the present application provides a garbage can exhaust device.

[0004] The present application provides a trash can exhaust device that adopts the following technical solution:

[0005] A garbage can exhaust device is installed on a collection box, wherein a collection bucket is arranged inside the collection box, and comprises an exhaust pipe and an exhaust fan, wherein one end of the exhaust pipe is connected to the collection box, and the exhaust fan is connected to an end of the exhaust pipe away from the collection box; a filter is arranged at an end of the exhaust pipe close to the collection box.

[0006] By adopting the above technical solution, the exhaust fan can extract the gas in the collection box to the outside through the exhaust pipe, so that the collection box is in a negative pressure state; thereby reducing the overflow of medical waste gas in the collection barrel into the room and reducing the possibility of harm to the human body. By setting a filter, the filter can reduce the situation where garbage in the trash can is sucked into the exhaust pipe, thereby reducing the possibility of blockage of the exhaust pipe and maintaining the exhaust effect of the exhaust fan on the collection box.

[0007] Optionally, it also includes a cleaning mechanism, which includes a cleaning brush, a cleaning box and a driving member, wherein the cleaning box is installed on the inner wall of the collection box; the cleaning box is hinged with a cover plate, and a torsion spring is provided at the hinge between the cover plate and the cleaning box, and the elastic force of the torsion spring drives the cover plate to cover the surface of the cleaning box under normal conditions; the cleaning box is normally located inside the cleaning box, and the driving member is used to drive the cleaning brush to brush the garbage on the surface of the filter into the interior of the cleaning box.

[0008] By adopting the above-mentioned technical solution, if there is garbage adsorbed on the surface of the filter, a driving member is used to push the cleaning brush out of the cleaning box. At this time, the cleaning brush abuts against the cover plate to put the cleaning box in an open state; and in the process of the cleaning brush abutting against the filter and moving toward one side of the cleaning box, the garbage on the surface of the filter is brushed into the cleaning box; and after the cleaning brush enters the cleaning box, the cover plate covers the opening of the cleaning box under the elastic force of the torsion spring, thereby reducing the situation where the garbage is blown out of the collection box again and attached to the surface of the filter.

[0009] By setting up a cleaning mechanism, the filter can be cleaned during the operation of the exhaust fan to maintain a negative pressure state in the collection box under normal circumstances, further reducing the overflow of medical waste gas to the outside; and starting the drive member to regularly drive the cleaning brush to clean the filter can reduce the need for staff to frequently clean the filter and maintain the exhaust effect of the exhaust fan.

[0010] Optionally, the driving member is configured as a cylinder, the cylinder is mounted on the cleaning box, the movable plug of the cylinder is mounted with a connecting plate, the connecting plate is provided with a slide groove, and the cleaning brush is slidably mounted in the slide groove; a first spring is arranged between the inner wall of the slide groove and the cleaning brush, and the elastic force of the first spring is used to drive the cleaning brush to abut against the filter screen under normal conditions;

[0011] A telescopic part is installed at the end of the cleaning brush, and a guide part is installed on the inner wall of the collection box. The guide part cooperates with the telescopic part and is used to drive a gap between the cleaning brush and the filter. When the telescopic part abuts against a side of the guide part away from the collection box, the guide part forces the telescopic part to move toward one side of the cleaning brush.

[0012] By adopting the above technical solution, when the cleaning brush moves toward one side of the filter, the telescopic part abuts against the guide part to create a gap between the cleaning brush and the filter, thereby reducing the situation in which the garbage is pushed away from the cleaning brush during the movement of the cleaning brush toward one side of the filter.

[0013] When the cleaning brush passes through the filter, the cleaning brush is no longer in contact with the guide portion and moves toward one side of the filter under the elastic force of the first spring; at this time, the driving cylinder moves the cleaning brush toward one side of the cleaning brush, which enables the telescopic part to abut against the end of the guide portion and move toward one side of the cleaning brush, so that the cleaning brush remains in contact with the filter when passing through the guide portion, thereby bringing the garbage into the cleaning box.

[0014] Optionally, the telescopic part includes a telescopic block and a second spring, a telescopic groove is opened at the end of the cleaning brush, and the telescopic block is movably installed in the telescopic groove; the second spring is installed between the telescopic groove and the inner wall of the telescopic block, and the second spring remains in a compressed state; a guide surface is provided on the side of the telescopic block close to the cleaning box to guide the telescopic block into the telescopic groove.

[0015] By adopting the above technical solution, the elastic force of the second spring drives the telescopic block to move toward the side away from the telescopic slot, so that the telescopic block can abut against the guide part and drive a gap between the cleaning brush and the filter. When the cleaning brush moves toward one side of the cleaning box, the guide surface abuts against the end of the guide part, and the telescopic block enters the telescopic slot under the guidance of the guide surface, so that the telescopic part cancels the cooperation with the surface of the guide part; so that the cleaning brush can pass through the guide part smoothly and keep the cleaning brush abutting against the filter, thereby improving the cleaning effect of the filter.

[0016] Optionally, the connecting plate is installed with a rubber sheet, and the rubber sheet covers the surface of the slide groove.

[0017] By adopting the above technical solution and arranging the rubber sheet, it is possible to reduce the situation where garbage enters the chute, so as to maintain the smooth sliding of the cleaning brush in the chute.

[0018] Optionally, the collection box is provided with a cleaning port for communicating with the cleaning box, and the collection box is provided with a sealing door for opening and closing the cleaning port.

[0019] By adopting the above technical solution, after the cleaning brush brushes the garbage into the cleaning brush, the cover plate is used to cover the opening of the cleaning box; the inside of the cleaning box and the inside of the collecting box can be separated. At this time, the sealing door opens the cleaning box, which can keep the negative pressure in the collecting box during the process of cleaning the garbage in the cleaning box, further reducing the overflow of medical waste gas.

[0020] Optionally, a rubber layer is provided on a side of the cover plate close to the cleaning box.

[0021] By adopting the above technical solution and providing the rubber layer, the sealing state inside the cleaning box is maintained during the process in which the cover plate covers the opening of the cleaning box.

[0022] Optionally, the collecting box is provided with a material taking port, and a accordion cover is slidably mounted on the collecting box, and the accordion cover covers the surface of the material taking port.

[0023] By adopting the above technical solution, a material taking port is provided to facilitate the removal of garbage in the collection bin for centralized treatment, and a negative pressure state in the collection box is maintained by providing an accordion cover.
