Abstract

The invention relates to the technical field of valves, in particular to a power distribution check valve and a range hood. The power distribution check valve comprises a ventilating valve body, a hose and a linked component. The hose comprises a rotary segment and a fixed segment. The ventilating valve body is provided with a transparent cavity. The fixed segment is fixedly connected into the transparent cavity. The rotary segment is fixedly connected with the linked component. The linked component is used for driving the rotary segment to rotate relative to the fixed segment, so that the twisted deformation occurs between the rotary segment and the fixed segment, and therefore, the size of an opening of the hose in the twisted deformation area is adjusted. The range hood comprises the power distribution check valve. According to the power distribution check valve and the range hood provided by the invention, the amount of passing air can be adjusted, in addition, the sealing effect is good under a complete closed condition, and the power distribution check valve has a good lampblack odor tainting preventing effect after being mounted in an air pipe of the range hood.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a power distribution check valve and a range hood. Background technique [0002] At present, many families will install a range hood in the kitchen, and a power distribution check valve is generally installed in the air duct of the range hood. [0003] Most of the existing power distribution check valves are provided with metal valve plates, and electric or mechanical force is used to drive the valve plates to open or close, and the one-way sealing of the power distribution check valve is realized by closing the valve plates. However, the power distribution check valve on the existing range hood has a structural gap at the valve plate, the sealing effect is poor, and it is easy to generate back smoke and odor. [0004] To sum up, how to overcome the above-mentioned defects of the existing power distribution check valve is a technical problem to be solved urgently by those skilled...
