On-off valve, waterway structure and water purifier

Abstract

The invention provides an on-off valve, a waterway structure and a water purifier, the on-off valve comprises a valve body, the valve body comprises a first chamber and a second chamber, the first chamber is provided with a flow inlet and a first flow guide port, the flow inlet is suitable for being connected with an external pipeline, the second chamber is separated from the first chamber, and the second chamber is provided with a flow outlet and a second flow guide port; one end of the valve cover is provided with a switch part, the switch part is arranged towards the valve body, the other end of the valve cover is provided with a pressure regulating part, the pressure regulating part is suitable for bearing external force, and the switch part has a closed state that the switch part moves towards the valve body under the external force and stops the first flow guide opening and the second flow guide opening from communicating. Under the action of the inner pressure of the first cavity, the valve body moves away from the valve body, and the first flow guide opening and the second flow guide opening are communicated in the opening state.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to an on-off valve, a waterway structure and a water purifier. Background technique [0002] At present, the common ultrafiltration water purifiers on the market mainly realize the interception of dirt and suspended solids in water through the physical filtration method of ultrafiltration membrane filaments. In order to prolong the service life of the water purifier, some of the dirt accumulated in the ultrafiltration membrane is usually discharged by flushing the ultrafiltration membrane. [0003] However, in the prior art, when the conventional on-off valve body installed on the wastewater waterway of the ultrafiltration filter element needs to be flushed, one way is to perform cumbersome and laborious manual opening and closing according to needs, and the other way is to set the valve body The electromagnetic valve for energization realizes the logical on-off demand of t...
