Abstract

The embodiment of the invention discloses a combined control mechanism. The combined control mechanism comprises a shell, a controlled component, a control component, a first passage and a second passage, wherein the shell is provided with a water inlet and a water outlet; the controlled component is arranged in the shell and divides the shell into a first cavity and a second cavity, the first cavity communicates with the water inlet, and the second cavity communicates with the water outlet; the control component can control the controlled component to move relative to the shell; the first cavity can communicate with the second cavity through the first passage; the first cavity can also communicate with the second cavity through the second passage; or, the first cavity can communicate withthe second cavity only through the first passage or only through the second passage. The combined control mechanism has the advantages that the structure is simple, the number of parts is small, thecost is low, and the size is small. According to the combined control mechanism, a throttling state, a flushing state and a closing state can be achieved through one control component, and only the position of the control component needs to be controlled, so that the control logic is simple.

Description

technical field

[0001] The present application relates to the field of fluid control, in particular to a combined control mechanism. Background technique

[0002] In the prior art, generally a waste water ratio electromagnetic valve is set at the waste water outlet of the filter membrane (such as reverse osmosis membrane or nanofiltration membrane, etc.) of the water purifier. Usually, the waste water ratio electromagnetic valve includes a first flow channel arranged in parallel and a second flow channel provided with a flushing electromagnetic valve. When the filter membrane of the water purifier is in the filtering state, the flushing solenoid valve is closed, and the filtered waste water flows out of the waste water ratio solenoid valve from the first channel under the action of the water pressure at the water inlet end. When the filter membrane of the water purifier is in the flushing state, the flushing electromagnetic valve is opened, and most of the water after rinsi...
