  • Publication number: 20220316616
    Abstract: A valve body structure is provided and includes a main pipe, a secondary pipe and a liquid storage tank, where the liquid storage tank stores a second liquid from the secondary pipe and controls whether the second liquid in the liquid storage tank flows into the main pipe by a solenoid valve, so that the second liquid is mixed with a first liquid in the main pipe. Therefore, the valve body structure can mix liquids without combining other components and has a lower cost and a smaller volume. As such, the issue of the remaining residual liquid when combined with other components for control, which reduces the control accuracy and even causes the problem of mixed pollution, can be avoided.
