As preferably, the transverse cutting area of described water chamber and imbibition chamber link equals the transverse cutting area in imbibition chamber.The transverse cutting area of water chamber and imbibition chamber link equals the transverse cutting area in imbibition chamber, can ensure the stable of negative pressure in imbibition chamber like this, ensure that the amount sucking liquid can not change.
As preferably, described water inlet pipe is arranged intake chamber and inlet seal ring recess.Intake chamber be used for water inlet, inlet seal ring recess for installing sealing ring, sealing when facilitating negative-pressure liquid suction pipe to be connected with miscellaneous part.
As preferably, described outlet pipe is arranged screw thread and exit seal ring recess.Screw thread can facilitate negative pressure lotion pipeline to be connected with miscellaneous part, and exit seal ring recess is for installing sealing ring, sealing when facilitating negative-pressure liquid suction pipe to be connected with miscellaneous part.
As preferably, in described outlet pipe free end water chamber, interior hexagonal is set.Interior hexagonal adopts die nut firmly when facilitating water inlet pipe to be connected with other parts.
The present invention has following beneficial effect: the intake antrum of water inlet pipe is used for current and enters, the current of water inlet accelerate by the accelerating cavity in body, current form negative pressure when accelerating through imbibition chamber, now, liquid sucting port sucks liquid and mixes in washing lotion chamber and water chamber with current, and mixed liquid is flowed out by the water chamber of outlet pipe, so just can realize automatically sucking cleaning fluid, fully mixed by imbibition chamber and water chamber again, good mixing effect.
