[0021] The technical scheme of the utility model will be described clearly and completely below in combination with the drawings. In the description of the utility model, it needs to be explained that the orientation or position relation of the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like is based on the orientation or position relation shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying the importance of the opposite.

[0022] The utility model will be described further below in combination with the drawings.

[0023] As Figures 1-5As shown, a cleaning valve array structure includes a plurality of pneumatic two-position four-way valves 1, a plurality of first pipes 2 are connected in series between the plurality of pneumatic two-position four-way valves 1; a first pneumatic two-position four-way valve 1 in the plurality of pneumatic two-position four-way valves 1 is connected to a liquid inlet 4 through a second pipe 3, and an end pneumatic two-position four-way valve 1 in the plurality of pneumatic two-position four-way valves 1 is connected to a third pipe 5, and the other end of the third pipe 5 is connected to the second pipe 3; a cleaning interface 6 at the lower end of each pneumatic two-position four-way valve 1 is respectively connected to a corresponding cleaning target point; and a waste outlet 7 at the lower end of each pneumatic two-position four-way valve 1 is connected to a waste disc 8.
