Waterway switching device, waterway system of vacuum cleaner and vacuum cleaner

Abstract

The invention discloses a waterway switching device, a waterway system of a dust collector and the dust collector. The waterway switching device comprises a valve body, a valve core, a driving elementand a plurality of sealing elements, wherein the valve core is movably arranged in a movable space, a liquid flow passage is arranged in the valve core, a valve core water inlet always communicates with a valve body water inlet, the driving element is arranged on the valve core to drive the valve core to move to enable a valve core water outlet to be switched to communicate with different valve body water outlets, the multiple sealing elements are arranged on the outer peripheral wall of the valve core and make contact with the inner wall of the movable space, and the sealing elements are distributed on the two sides of the valve core water inlet and the two sides of the valve core water outlet. According to the waterway switching device provided by the embodiment, the valve core can be controlled to move in the movable space of the valve body through the driving element so as to switch the valve core water outlet to communicate with the different valve body water outlets, water is discharged from the corresponding valve body water outlets, therefore, waterway flow requirements in different working modes of the dust collector are met, the structure is simple, and operation is convenient.

Description

technical field

[0001] The present invention relates to the technical field of vacuum cleaners, in particular, to a waterway switching device, a waterway system of a vacuum cleaner, and a vacuum cleaner. Background technique

[0002] With the development of science and technology and the change of consumption concept, a simple dry vacuum cleaner can no longer meet the daily needs of consumers. There are some vacuum cleaners and carpet and floor cleaning machines that can absorb water on the market. In the related art, the water path of the washing machine is relatively simple, and only one water path is provided, or it is divided into two or more water paths through a flow diversion device, which has a complex structure and is inconvenient to operate. Contents of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a waterway switching device, which has the a...
