As shown in fig. 1 to 4, a pneumatic driving device of a drain valve according to a first embodiment of the present utility model includes:
a first shuttle valve 1a including a first valve body 11 having a first inlet 111, a second inlet 112, and an outlet 113, and a first valve core 12 movably provided in the first valve body 11;
a drain valve 2 provided with a pneumatic driving assembly 21 for controlling the drain valve 2 to open the drain, the pneumatic driving assembly 21 being in communication with the outlet 113 of the first shuttle valve 1 a;
an air pump 3 communicating with the first inlet 111 of the first shuttle valve 1 a;
a first manual air supply assembly 4a in communication with the second inlet 112 of the first shuttle valve 1 a;
when the air pump 3 is turned on, the first valve core 12 communicates with the first inlet 111 of the first shuttle valve 1a and the outlet 113 of the first shuttle valve 1a, and cuts off the communication between the second inlet 112 of the first shuttle valve 1a and the outlet 113 of the first shuttle valve 1a, at this time, the air pump 3 can supply air to the pneumatic driving assembly 21 of the drain valve 2 through the first shuttle valve 1a so that the drain valve 2 opens the drain; when the first manual air supply assembly 4a is opened, the first valve body 12 communicates with the second inlet 112 of the first shuttle valve 1a and the outlet 113 of the first shuttle valve 1a, and cuts off the communication between the first inlet 111 of the first shuttle valve 1a and the outlet 113 of the first shuttle valve 1a, and at this time, the first manual air supply assembly 4a can supply air to the air-operated driving assembly 21 of the drain valve 2 through the first shuttle valve 1a so that the drain valve 2 opens the drain.
The air release channel 8 is arranged between the air pump 3 and the first shuttle valve 1a, and air in the pneumatic driving assembly 21 of the drain valve 2 can be discharged through the air release channel 8, so that the starting piece 23 of the drain valve 2 can be smoothly closed to finish the drainage without being controlled by the pneumatic driving assembly 21 after air release.

The electromagnetic valve 5 and the air pump 3 can be controlled by a main control board (not shown), and the main control board controls the electromagnetic valve 5 to be in a closed state when the air pump 3 works, so that the air output by the air pump 3 is prevented from being discharged from the air discharge channel 8. The solenoid valve 5 may be a normally open solenoid valve (i.e., in an open state when de-energized) or a normally closed solenoid valve (i.e., in a closed state when de-energized). Of course, the electromagnetic valve 5 may not be provided to control the opening and closing of the air release channel 8, but the air release channel 8 may be directly communicated with the outside atmosphere, and the air release amount of the air release channel 8 may be designed to be smaller than the air supply amount of the air pump 3, so that the air output by the air pump 3 will flow to the pneumatic driving assembly 21 mostly, and only a small portion will be released from the air release channel 8, so that the air pump 3 can provide sufficient air amount to the pneumatic driving assembly 21.
In this embodiment, the first manual air supply assembly 4a employs a pneumatic button commonly known in the art, which may generally include a cylinder or an air bag, a piston for compressing the cylinder or the air bag, and the like, and will not be described in detail herein.

When the stroke of the actuating member 23 of the drain valve 2 driven by the pneumatic driving assembly 21 is large, the drain valve 2 performs full-displacement drainage, and when the stroke of the actuating member 23 of the drain valve 2 driven by the pneumatic driving assembly 21 is small, the drain valve 2 performs half-displacement drainage, and the technology of controlling the actuating member 23 to move different strokes to realize the full-drainage function and the half-drainage function of the drain valve 2 is a known technology, and will not be explained in detail here.

Likewise, the third manual air supply assembly 4c may also employ a pneumatic button as is common in the art.
Referring to fig. 7, the first and third manual air supply assemblies 4a and 4c are preferably assembled together, so that the structure is more compact and the installation is facilitated.
In specific implementation, the air supply amounts of the first manual air supply assembly 4a and the third manual air supply assembly 4c may be set to be different, so that the strokes of the actuating member 23 of the drain valve 2 driven by the pneumatic driving assembly 21 and the second pneumatic driving assembly 22 are different, thereby being capable of controlling the drain valve 2 to perform full-displacement drainage and half-displacement drainage.
