Optionally, the second water tank 20 includes a water tank body and a heating member, the water tank body is provided with a water inlet 201 and a steam outlet, for example, the water inlet 201 is provided on the peripheral wall of the water tank body, the steam outlet is provided on the top of the water tank body, the heating member is used for heating the water in the water tank body into steam, and the top of the water tank body is provided with an exhaust valve.
For example, the heating element is a PTC heater, wherein PTC is an abbreviation of Positive Temperature Coefficient, which means a semiconductor material or a component having a large Positive Temperature Coefficient. In general, reference to PTC refers to a positive temperature coefficient thermistor, abbreviated as a PTC thermistor. The PTC heater is also called as PTC heating body, and is composed of PTC ceramic heating elements and an aluminum tube. The PTC heating element has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant-temperature and electricity-saving electric heater.

In some examples, the density of the cartridge 2 is the same as the density of water, so FFloating bodyAnd G may cancel each other out, for a simplified force analysis with the example in fig. 1, F ═ F1+F2And due to F1＝P1S1+ρgh1S1，F2＝P2S2+ρgh2S2Wherein P is1Is the pressure of the gas in the first tank 10, P2Is the atmospheric pressure in the second tank 20, where S1And S2Approximately equal, then F ═ P1+P2+ρgh1+ρgh2]S1Then the direction of F is only equal to P1+P2+ρgh1+ρgh2Positive and negative values of (c).
The operation of the water tank assembly 100 will now be briefly described, with reference to FIG. 2, before the water tank assembly 100 is heated, at time P1＝-P2，h1＞h2Thus P is1+P2+ρgh1+ρgh2F > 0, so that the valve body 2 moves to unidirectionally conduct the valve chamber 11 in a direction from the first port 111 to the second port 112 and the first tank 10 automatically supplies water to the second tank 20, and finally h2＝h1That is, the liquid level in the second tank 20 and the liquid level in the first tank 10 are finally made equal (F is 0, and the check valve 30 is between conduction and non-conduction).
Then, the exhaust valve is closed, and when the heating member heats the water in the second water tank 20, the air pressure in the second water tank 20 is gradually increased, so that P1+P2+ρgh1+ρgh2If the water level in the second water tank 20 is less than 0, namely the acting force F borne by the valve core 2 is less than 0, the one-way valve 30 is not communicated, so that the water in the second water tank 20 cannot flow back to the first water tank 10, and meanwhile, the steam can be discharged to the indoor environment through the steam outlet to humidify the indoor environment;
when the heating element stops heating, if the exhaust valve is not opened in advance, the steam is condensed, and at the moment P2Is reduced while the liquid level of the second tank 20 is lower than the liquid level of the first tank 10, so that P1+P2+ρgh1+ρgh2When the acting force F on the second valve core 2 is greater than 0, referring to fig. 2, the check valve 30 is turned on, and the first water tank 10 automatically supplies water to the second water tank 20;
when the heating member stops heating, if the exhaust valve is opened in advance, the outside atmosphere balances the pressure in the second water tank 20 and makes P2＝-P1And because then h1＞h2Referring to FIG. 2, when the second valve body 2 is acted by a force F > 0, the check valve 30 is opened, and the first water tank 10 automatically supplies water to the second water tank 20, as shown in FIG. 3, because P is the same2＝-P1So finally h2＝h1I.e. the level of the second reservoir 20 is equal to the level of the first reservoir 10 (in this case F is 0 and the non-return valve 30 is between open and closed).
Alternatively, referring to fig. 10, the step portion 12 includes a first step surface 121 and a second step surface 122 intersecting with each other, the first step surface 121 is disposed facing the valve element 2, a seal engagement portion 123 is disposed on the first step surface 121, the seal engagement portion 123 includes a first annular surface 1231 and a second annular surface 1232, the first annular surface 1231 and the second annular surface 1232 respectively extend in the circumferential direction of the valve chamber 11, an end of the first annular surface 1231 away from the first step surface 121 intersects with an end of the second annular surface 1232 away from the first step surface 121 to define an abutment line 1233, and when F < 0, the valve element 2 abuts against the abutment line 1233 to be in line seal engagement with the seal engagement portion 123.
