Abstract:
The present application provides a muffler, comprising a cylindrical housing defining an anechoic chamber, an anechoic chamber inlet and an anechoic chamber outlet that are located at two opposite axial ends of the housing, and at least one partition plate, at least one muffling pipe, and at least one liquid discharging pipe that are located in the anechoic chamber. The at least one liquid discharging pipe is provided on the at least one partition plate and extends a certain distance along the axis of the housing on at least one side of the corresponding partition plate. Each liquid discharging pipe defines a liquid discharging channel penetrating through the corresponding partition plate. Each liquid discharging pipe is arranged in close contact with the housing or is partially formed by the housing. The position of the anechoic chamber outlet relative to the at least one liquid discharging pipe is configured so that a liquid flowing out from the at least one liquid discharging pipe can be discharged through the anechoic chamber outlet. The muffler of the present application is part of an exhaust channel of a compressor, and the liquid discharging channel provided in the anechoic chamber can meet the requirement of timely discharging a lubricating liquid from the muffler, and likewise cannot reduce the muffling effect of the anechoic chamber.
