[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0018] See attached Figure 1-7 A diaphragm valve for a large industrial washing machine washing dragon dispenser, comprising a valve body 13, a valve core water cavity 6 is provided at the center of the valve body 13, an outer ring water cavity 8 is provided at the outer edge of the valve core water cavity 6, a pipeline port Ⅰ1, a pipeline port Ⅱ2, a laundry liquid inlet 4, a diaphragm valve outlet 5, and a gas inlet 7 are respectively provided on the periphery of the valve body 13, a connecting hole A11 is formed between the outer ring water cavity 8 and the pipeline port Ⅰ1, and a connecting hole B9 is formed between the outer ring water cavity 8 and the pipeline port Ⅱ2 (see Figure 2 ), the pipe opening Ⅰ1, the pipe opening Ⅱ2 and the outer ring water cavity 8 are connected to each other through the through hole A11 and the connecting hole B9 (see Figure 6 ), the valve core water chamber 6, the gas inlet 7, the laundry liquid inlet 4 and the diaphragm valve outlet 5 are interconnected, a partition 15 is provided between the outer ring water chamber 8 and the laundry liquid inlet 4, the laundry liquid inlet 4 is not connected to the outer ring water chamber 8, and a one-way valve is provided on the laundry liquid inlet 4 and the gas inlet 7; a diaphragm connecting hole 10 is provided on the valve body 13, the valve body 13 is fixedly connected to the diaphragm 12 through the diaphragm connecting hole 10, the diaphragm 12 is connected to the cylinder push rod 14, the valve body 13 is fixedly connected to the cylinder 3 through screws, and the diaphragm 12 is pressed. The push rod 14 of the cylinder is connected to the diaphragm 23, the cylinder 3 and the valve body 13 are fixed with screws, and the rubber diaphragm is pressed at the same time to ensure that the valve body does not leak, and the diaphragm valve is in a normally closed state (see Figure 4 ).

[0019] Multiple diaphragm valves can be connected to each other, with the pipe port II2 of one diaphragm valve connected to the pipe port I1 of another diaphragm valve (see Figure 7 ). Since the type of detergent required for each washing chamber is fixed, there is no need to switch between various detergents. Each washing chamber is controlled by a separate diaphragm valve. The number of washing chambers in a large washing machine can be matched with a corresponding diaphragm valve. Multiple diaphragm valves can use public water, reduce volume, save space, and reduce costs.

[0020] The detergent inlet 4 and the gas inlet 7 are both equipped with a one-way valve, and the detergent, water and gas can only flow out from the diaphragm valve outlet 5. When the washing dragon needs detergent, the detergent is pumped into the detergent inlet 4 in a corresponding amount, and then the cylinder 3 is activated to open the diaphragm valve diaphragm 12 (such as Figure 5), water enters the water cavity of the valve core from the outer ring water cavity of the diaphragm valve, and then flows to the outlet of the diaphragm valve. After adding water for a certain period of time, the diaphragm valve is closed, and compressed air is injected from the gas inlet for a certain period of time.

[0021] The purpose of opening the diaphragm valve: the laundry detergent will remain in the delivery pipeline between the diaphragm valve and the washing dragon, and the pipeline is flushed with water.

[0022] The purpose of flushing compressed air is to make the pipeline clean and free of a mixture of detergent and water.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
