Claim 0:
1. A valve body, comprising a first cavity, a second cavity, a valve core and an elastic reset member; wherein the first cavity and the second cavity communicate with each other through a second water inlet of the second cavity;
the second cavity comprises a second water outlet arranged on a cavity wall of the second cavity and a first through hole arranged on the cavity wall of the second cavity opposite to the second water inlet;
the first cavity comprises a first water inlet provided on a cavity wall of the first cavity;
the valve core, arranged in the first cavity and coaxial with the second water inlet, comprises a piston and a first ejector rod being coaxial with the piston;
one end of the piston is a free end, and another end of the piston is a switch end; the switch end is fixedly connected to one end of the first ejector rod; and an end surface of the switch end fits with the second water inlet, and is configured to open or close the second water inlet;
the first ejector rod passes through the second water inlet and the first through hole; another end of the first ejector rod sticking out of the second cavity is a second movable end; the second movable end is a curved surface structure, and configured to push the piston to open the second water inlet when the second movable end is compressed in an axial direction;
one end of the elastic reset member is a first movable end, and another end of the elastic reset member is a first fixed end; the first movable end abuts against the valve core; and the first fixed end abuts against the first cavity or the second cavity, and is configured to press the valve core to move in the axial direction to close the second water inlet;
wherein the valve body further comprises a base; the base has a first groove; an inner wall of the first groove is fixedly connected to the outer wall of the second cavity; a bottom of the first groove is provided a third through hole coaxial with the second water inlet the first ejector rod passes through the third through hole;
the base is an upper wall of a third cavity; the third cavity comprises a rocker arm connected to a rotating shaft of a cavity wall of the third cavity, a reset hole penetrating through an upper wall of the third cavity, and a second ejector rod penetrating through a lower wall of the third cavity;
the rocker arm has an “L”-shaped longitudinal section and comprises a long arm, a short arm fixedly connected to the long arm and the rotating shaft arranged at a connecting portion; the rocker arm is slidably connected with the first ejector rod; an end of the long arm passes through the reset hole to control a downward movement of the end of the long arm, causing the first ejector rod to move upward through the short arm, such that the second water inlet is opened by the piston;
the second ejector rod is arranged below the end of the long arm and is configured to control the end of the long arm to move upward, the short arm drives the first ejector rod to move downwards, such that the second water inlet is closed by the piston.
