Document Type and Number:
WIPO Patent Application WO/2022/247529
Kind Code:
A1
Abstract:
The present invention provides a switcher, comprising: two or more chambers, each chamber being provided with at least one opening, respectively; and a rotating rod passing through the chambers in sequence. The rotating rod is provided with a plurality of cam portions formed opposite to different openings. The cam portions respectively drive pistons arranged in one-to-one correspondence to the cam portions to telescopically move with respect to the openings, and are used for controlling sealing structures provided on different pistons to correspondingly close or open the corresponding openings. Therefore, when different media flow through different chambers, one switcher can be used for corresponding on-off switching control, so that the purpose of implementing on-off switching of a water channel and an air channel simultaneously can be achieved, thereby enriching the application scenarios of the switcher. In addition, the present invention further provides a dispensing apparatus equipped with the switcher, and laundry treatment equipment.
