The buffer chamber 11 has two configurations:
first, referring to fig. 1, the buffer chamber 11 is a bottom of a gas drainage pipe, which is located above the water collection tank 10, and when the first valve 20 is opened, water in the buffer chamber 11 flows toward the water collection tank 10 by virtue of gravity of the water.
Secondly, referring to fig. 5, the buffer chamber 11 is a buffer tank located above the water collecting tank 10, the buffer chamber 11 can be communicated with a gas drainage pipe, the buffer chamber 11 and the upper part of the partition plate of the water collecting tank 10 are fixed with a first valve 20, and the lower part of the partition plate is fixed with a sealing door.
If the first valve 20 is closed (at this time, the water collection tank 10 is in a drainage state, and the internal air pressure is equal to or higher than the atmospheric pressure), the air pressure 9 (always negative pressure) of the buffer chamber 11 is lower than the air pressure of the water collection tank 10, and the sealing door is sealed on the partition plate by the air pressure of the water collection tank 10, so that a sealing state is formed. If the first valve 20 is opened (at this time, the water collection tank 10 is in a sealed state), the air pressure of the buffer chamber 11 is equal to the air pressure of the water collection tank 10 (communicated by the first valve 20), and the water in the buffer chamber 11 flows into the water collection tank 10 by gravity, so that a water storage state is formed.

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.
When the switch 51 of the external air source 50 is opened, the high-pressure air simultaneously enters the air pipeline A71, the air pipeline B72, the air pipeline C73, the air pipeline D74 and the pressurized water air pipe 90.
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 line C73 is communicated with the gas inlet of the control valve B62, the spool is originally on the side of the gas inlet control port a, at this time, the gas line C73 is communicated with the actuating gas line B86, the spool 98 moves to the side of the first gas control port 95, so that the first valve 20 (between the first inlet 93 and the outlet 94) is communicated and kept communicated, and the first valve 20 is in an open state.
Meanwhile, the gas pipeline B72 is communicated with the gas inlet of the communication control valve A60, the spool is originally arranged on one side of the gas inlet control port A, the gas pipeline B72 is communicated with the gas pipeline G77, and at the moment, two actions are triggered:
first, the gas line branch C771 gets the signal and the pneumatic delay pressure controller a53 starts working.
Secondly, the gas line branch D772 communicates with the gas inlet control port B of the control valve B62 to continue to press the spool to be originally located at the gas inlet control port a side, the gas line C73 communicates with the actuating gas line B86, the gas in the actuating gas line B86 enters the second gas control port 96, the spool 98 moves to the first gas control port 95 side, and the first valve 20 is kept open (meanwhile, the second valve 21 is turned off).
Draining water for the first time:
after time T1 (time T1 is the water discharge time, T1 can be manually adjusted in advance), the pneumatic time-delay pressure controller a53 makes the gas line H78 ventilate (that is, makes the gas line a71 communicate with the gas line H78), the gas line H78 presses the spool of the control valve a60 to move to the side of the air inlet control port B, the gas line B72 communicates with the gas line F76, at this time, four changes occur simultaneously:
firstly, a gas pipeline branch B762 obtains a signal, and a pneumatic time-delay pressure controller B54 starts to work;
secondly, the branch C771 of the gas pipeline has no signal, the pneumatic delay pressure controller A53 stops working, and the gas pipeline H78 has no signal;
third, the gas line branch D772 is disconnected, and it is no longer in communication with the inlet control port B of the control valve B62, and the gas pressure at the inlet control port B is reduced.
Fourthly, the gas line branch a761 receives a signal to communicate with the intake control port a of the control valve B62, the spool of the control valve B62 moves toward the intake control port B side to communicate the gas line C73 with the actuating gas line a85, and the spool 98 moves toward the second gas control port 96 side to open the second valve 21 (at the same time, the first valve 20 is opened).
The second valve 21 is opened and the first valve 20 is closed simultaneously, and at this time, the water discharging time of the water discharger is the same, referring to fig. 1, the water collecting tank 10 is sealed with the buffer chamber 11 and is communicated with the outside through the air inlet 12 to discharge water.
Water collection again:
after time T2 elapses (time T2 is the water collecting 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 D74 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 four changes occur simultaneously:
firstly, a gas pipeline branch C771 obtains a signal, and a pneumatic delay pressure controller A53 starts working;
secondly, the gas pipeline branch B762 has no signal, the pneumatic time-delay pressure controller B54 stops working, and the gas pipeline I79 has no signal;
third, the gas line branch a761 is disconnected, and it is no longer in communication with the inlet control port a of the control valve B62, and the gas pressure at the inlet control port a decreases.
Fourthly, the gas line branch D772 receives a signal to communicate with the inlet control port B of the control valve B62, the spool of the control valve B62 moves toward the inlet control port a to communicate the gas line C73 with the actuating gas line a86, the spool 98 moves toward the first gas control port 95, and the first valve 20 remains open (while the second valve 21 is open).
The first valve 20 is opened and the second valve 21 is closed at the same time, and at this time, the water collecting state of the water discharger is the time, referring to fig. 1, the water collecting tank 10 is communicated with the buffer chamber 11, and meanwhile, the outside is not communicated any more, so that water is collected.
After the time T1 elapses, the operation is switched to the water discharge time as described above.
When the time T2 elapses, the operation is switched to the water collecting time as described above.
And time T1, T2 are adjusted well in advance (if not suitable, can readjust), have realized the automatic switch of discharging water, catchment, it is very convenient.
