[0002] Patent announcement number CN 21682779U discloses an exhaust device for gas purification of garbage trucks, which belongs to the technical field of garbage truck purification equipment, including a garbage truck body, an exhaust fan fixedly installed on the top of the garbage truck body, an input end of the exhaust fan fixedly connected to an air intake pipe, an output end of the exhaust fan fixedly installed to an exhaust pipe, an end of the exhaust pipe away from the exhaust fan fixedly connected to a purification box, the purification box is overlapped on both sides of the garbage truck body, and the outer surface of the purification box is provided with a fixed and disassembly structure for fixing the position of the purification box. The exhaust device for gas purification of garbage trucks uses an exhaust fan, an air intake pipe and an exhaust pipe in coordination. The exhaust fan transports the odorous gas inside the garbage truck body to the purification box. Then, the odorous gas is filtered and purified in the purification box and then discharged through the coordination of the purification box, the filter, the activated carbon and the exhaust hole, thereby achieving the effect of quickly purifying and filtering the odorous gas inside the garbage truck body. Although the above method can purify the odor inside the vehicle body, it is necessary to manually remove the purification box each time, and then open the purification box to clean and replace the filter and activated carbon inside. It is inconvenient to disassemble and assemble the purification box and the filter for cleaning for a long time, and the filter cannot be automatically cleaned, which reduces the convenience. For this reason, we propose a filtering structure for the exhaust device of the garbage truck. Utility Model Content
