Abstract
A check valve for a ventilator includes a housing assembly defining a flow channel and a flow guide assembly. The flow channel defines an air outlet. The flow guide assembly is disposed in the flow channel. The flow guide assembly includes a first baffling sleeve and a second baffling sleeve that are disposed in an axial direction of the flow channel in sequence. A first flow passing opening is defined in the first baffling sleeve. One side of the first baffling sleeve away from the first flow passing opening is inclined toward the air outlet. One side of the second baffling sleeve is inclined toward the air outlet. The second baffling sleeve faces the first flow passing opening. A projection of the second baffling sleeve completely overlaps a projection of the first flow passing opening on the horizontal cross section of the flow channel.
