The working principle is as follows:
taking the water discharger in fig. 1 as an example, the following is explained:
preparing:
when the water collecting device is just operated, the water collecting state is as follows: the water of the buffer chamber 11 is introduced into the water collecting tank 10. At this time, the first valve 20 is in an open state and the second valve 21 is in a closed state.
The switch 51 of the external gas source 50 is opened, and high-pressure gas simultaneously enters the gas pipeline A71, the gas pipeline B72, the gas pipeline C73, the gas pipeline D74 and the gas pipeline E75.
Because the gas line branch C771 has no signal for the moment, the pneumatic delay pressure controller a53 is inactive for the moment.
Because the gas line branch B762 has temporarily not been signaled, the pneumatic delay pressure controller B54 is temporarily disabled.
The gas pipeline B72 is communicated with the execution gas pipeline A81, the execution gas pipeline A81 is communicated with the first valve 20, and the first valve 20 is kept in an open state.
The gas pipeline D74 is communicated with the execution gas pipeline C83, the execution gas pipeline C83 is communicated with the second valve 21, and the second valve 21 is kept in a closed state.

firstly, a gas pipeline C73 is communicated with a gas pipeline F76, a gas pipeline branch B762 enters a pneumatic time-delay pressure controller B54, and a pneumatic time-delay pressure controller B54 starts to work; meanwhile, the gas pipeline branch A761 is communicated with the reversing valve B56 to enable the reversing valve B56 to carry out reversing adjustment, the gas pipeline D74 is communicated with the execution gas pipeline D84, the execution gas pipeline D84 is communicated with the second valve 21, and the second valve 21 is enabled to be in an open state;
secondly, the gas line C73 is no longer communicated with the gas line G77, the gas line branch C771 has no signal temporarily, the pneumatic delay pressure controller a53 does not work temporarily, and the gas line H78 no longer presses the spool 576; meanwhile, the gas pipeline branch D772 is no longer communicated with the reversing valve a55, the reversing valve a55 performs reversing adjustment, so that the gas pipeline B72 is communicated with the executing gas circuit B82, and the first valve 20 is in a closed state.

Water collection again:
after time T2 elapses (time T2 is the water collection time, and time T2 can be manually adjusted in advance), the pneumatic time-delay pressure controller B54 vents the gas line I79 (i.e. the gas line E75 is communicated with the gas line I79), the gas line I79 forces the spool 576 to move toward the side of the inlet control port a574 (because the gas line H78 no longer forces the spool 576), and two changes occur simultaneously:
firstly, a gas pipeline C73 is communicated with a gas pipeline G77, a gas pipeline branch C771 enters a pneumatic delay pressure controller A53, and a pneumatic delay pressure controller A53 starts to work; meanwhile, the gas pipeline branch D772 is communicated with the reversing valve a55 to enable the reversing valve a55 to perform reversing adjustment, the gas pipeline B72 is communicated with the executing gas pipeline a81, the executing gas pipeline a81 is communicated with the first valve 20, and the first valve 20 is in an open state;
secondly, the gas line C73 is no longer communicated with the gas line F76, the gas line branch B762 has no signal temporarily, the pneumatic time-delay pressure controller B54 does not work temporarily, and the gas line I79 no longer presses the spool 576; meanwhile, the gas line branch a761 is no longer communicated with the reversing valve B56, and the reversing valve B56 performs reversing adjustment, so that the gas line D74 is communicated with the actuating gas line C83, and the second valve 21 is in a closed state.
