In this embodiment, the liquid supply system further includes a gas valve 14 for communicating atmospheric pressure and blocking atmospheric pressure, the gas valve 14 being disposed at the pooling position. The "air valve" structure herein does not in itself obstruct the flow of liquid, but rather, utilizes the three conduit directions in which the atmospheric pressure communicated upon switching of the state of air valve 14 is forced to the pooling position to obstruct the flow of liquid. In addition, it should be noted that the specific form of the "air valve" in the present invention is not limited, and the air valve may be a special valve body in a narrow sense, or a valve body structure in a non-narrow sense, and may be controlled by an intelligent or mechanical signal, or may be controlled manually. In short, it is sufficient if the purpose of switching the communicating atmospheric pressure and the blocking atmospheric pressure can be achieved.
Specifically, when the liquid supply system needs to supply liquid, that is, power needs to be supplied to make the liquid in the first liquid storage tank 13 and the second liquid storage tank 23 respectively flow into the first communicating pipe 11 and the second communicating pipe 21 and flow out from the first liquid outlet after the completion of collection, the air valve 14 may be controlled to be closed to isolate the collection position from the atmospheric pressure, and at this time, the liquid may smoothly flow out from the first liquid outlet under the action of power. When the liquid supply system stops supplying liquid, the air valve 14 can be controlled to be opened so as to communicate the gathering position with the atmospheric pressure, and the atmospheric pressure can press towards the three pipeline directions of the gathering position.
It should be noted that in the present invention, "the air valve is disposed at the collecting position" may be that the air valve 14 is directly disposed at the collecting position; or indirectly at the collection position with valve 14 not below the collection position, for example, a pair of vent pipes may be provided to the collection position with valve 14 at the end of the vent pipe remote from the collection position.

When the liquid supply system stops supplying liquid, the vent pipe 17 is communicated with the atmospheric pressure, so that the atmospheric pressure can be pressed towards the three pipeline directions of the collecting position, and the siphonage phenomenon can be avoided.
FIG. 3 shows a third embodiment of the liquid supply system of the present invention.
The main differences between this embodiment and the first embodiment of the liquid supply system are: the setting of gas valve 14 is different.
In this embodiment, the air valve 14 is disposed on the first communication pipe 11 and is higher than the collecting position. With this arrangement, it is possible to avoid both the siphon phenomenon that may be caused at the first communication pipe 11 and the siphon phenomenon that may be caused at the second communication pipe 21.

When the liquid supply system stops supplying liquid, the air valve 14 may be controlled to open to communicate the first communication pipe 11 with the atmospheric pressure, and at this time, the atmospheric pressure may press to both sides of the vent pipe 17, so that the liquid on one side flows back to the first liquid storage tank 13, and the liquid on the other side may flow into the second liquid storage tank 23 or flow out from the first liquid outlet under the action of the atmospheric pressure.
Similarly, in the present invention, "the air valve is disposed on the first communicating pipe" may also be disposed directly or indirectly by the air valve 14, which is not limited herein. Reference may be made in particular to the description of the first embodiment of the liquid supply system.

In this case, the second power device 22 on the second communication pipe 21 can use a peristaltic pump, so that the problem of quantitative determination caused by pumping out the liquid in the second liquid storage tank 23 when the first power device 12 is in the liquid pumping state can be avoided. Furthermore, the second power device 22 may also prevent the occurrence of the siphon phenomenon by using a peristaltic pump.
FIG. 4 shows a fourth embodiment of the liquid supply system of the present invention.
The present embodiment differs from the first embodiment of the liquid supply system in that:
the liquid supply system utilizes the vent pipe 18 connected to the first communicating pipe 11 instead of the design of the third embodiment in which the air valve is arranged in the first communicating pipe, at least part of the pipe section of the vent pipe 18 is higher than the highest position of the first communicating pipe 11 and the second communicating pipe 21, and the vent pipe 18 is communicated with the atmosphere.
Because at least part of the pipe section of the vent pipe 18 is higher than the highest position of the first communicating pipe 11 and the second communicating pipe 21, when the liquid supply system supplies liquid by using the power of the liquid supply system, the liquid does not overflow from the vent pipe 18, and the reliable liquid supply of the liquid supply system can be ensured. When the liquid supply system stops supplying liquid, because the vent pipe 18 is communicated with the atmospheric pressure, the atmospheric pressure can press the two sides of the vent pipe 18 at the moment, so that the liquid on one side flows back to the first liquid storage tank 13, and the liquid on the other side can flow into the second liquid storage tank 23 or flow out from the first liquid outlet under the action of the atmospheric pressure, and further the occurrence of siphonage can be avoided.
In this embodiment, the position of the first communication pipe 11 where the vent pipe 18 is disposed is the highest position, so as to achieve better siphon-proof effect.
FIGS. 5 and 6 show a fifth embodiment of the liquid supply system of the present invention.
In this embodiment, a peristaltic pump (not shown) is connected to the second communication pipe 21, and the peristaltic pump can selectively adjust the flow direction of the liquid in the second communication pipe 21. The peristaltic pump is convenient to control the conveying of the liquid.
