Wherein F ═ F₁+F₂+F_{Floating body}+G，F₁Is the resultant force of the liquid pressure on the side of the valve core 2 adjacent to the first water tank 10 and the acting force of the atmosphere on the valve core 2, F₂Is the resultant force of the liquid pressure on the side of the valve core 2 adjacent to the second water tank 20 and the acting force of the gas in the second water tank 20 on the valve core 2, F_{Floating body}Is the buoyancy of the valve element 2, and G is the gravity of the valve element 2.

Specifically, when F₁₁＝-F₁₂If at this time ρ gh₁S₁+ρgh₂S₂+F_{Floating body}If + G is greater than 0, F is greater than 0, the valve core 2 moves to unidirectionally conduct the valve cavity 11 in the direction from the first port 111 to the second port 112, the first water tank 10 automatically supplies water to the second water tank 20, and finally, under the combined action of the air pressure of the first water tank 10 and the air pressure of the second water tank 20, the liquid level in the second water tank 20 is equal to the liquid level in the first water tank 10; if at this time h₁＜h₂While ρ gh₁S₁+ρgh₂S₂+F_{Floating body}And G is less than 0, namely F is less than 0, the valve core 2 moves to be in sealing fit with part of the inner wall line of the valve cavity 11 to cut off the valve cavity 11, the sealing effect is good, the one-way valve 30 is not communicated, so that water in the second water tank 20 cannot flow back to the first water tank 10, and finally the liquid level height in the second water tank 20 is greater than that of the first water tank 10. The valve core 2 is arranged in the valve cavity 11 in a manner of moving up and down, so that the influence of the gravity of the valve core 2 on the moving direction of the valve core 2 can be reduced, the valve core 2 is prevented from moving and deviating due to the influence of the gravity of the valve core 2, the one-way sealing effect of the valve core 2 is improved, the valve core 2 is prevented from being clamped, and the working reliability of the water tank assembly 100 is improved;

when F is present₁₁＞-F₁₂(the air pressure of the first water tank 10 is greater than the air pressure in the second water tank 20), if F is greater than 0 at this time, the valve core 2 moves to unidirectionally conduct the valve chamber 11 in the direction from the first port 111 to the second port 112 and the first water tank 10 automatically supplies water to the second water tank 20, if F is less than 0 at this time, the valve core 2 moves to cooperate with a part of the inner wall of the valve chamber 11 to shut off the valve chamber 11, the check valve 30 is not conducted, but when the atmospheric pressure in the second water tank 20 is restored to the standard atmospheric pressure, the liquid level in the second water tank 20 is greater than or equal to the liquid level of the first water tank 10;

when F is present₁₁＜-F₁₂(the air pressure of the first tank 10 is less than the air pressure of the second tank 20), if F is greater than 0, the valve core 2 moves to unidirectionally conduct the valve chamber 11 in the 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 if F is less than 0, the valve core 2 moves to cooperate with a part of the inner wall of the valve chamber 11 to cut off the valveThe chamber 11 and the check valve 30 are not opened, but when the atmospheric pressure in the second tank 20 is restored to the normal atmospheric pressure, the liquid level in the second tank 20 is equal to or higher than the liquid level in the first tank 10.

Thus, by providing the check valve 30 between the first tank 10 and the second tank 20, the water in the second tank 20 is not reversely flowed to the first tank 10, when the acting force F borne by the valve core 2 is larger than 0, the first water tank 10 can automatically supply water to the second water tank 20 without additional power, and when the air pressure in the second water tank 20 is restored to the standard atmospheric pressure, the liquid level in the second water tank 20 is equal to or higher than the liquid level in the first water tank 10, so that the amount of water in the second tank 20 can be controlled, and by making the valve core 2 movably up and down provided in the valve chamber 11, the influence of the gravity of the valve core 2 on the moving direction of the valve core 2 can be reduced, the phenomenon that the valve core 2 moves to deviate due to the influence of the gravity of the valve core 2 is avoided, the one-way sealing effect of the valve core 2 is favorably improved, the valve core 2 can be prevented from being blocked, and the working reliability of the water tank assembly 100 is further improved.

According to the water tank assembly 100 of the embodiment of the present invention, the check valve 30 is disposed between the first water tank 10 and the second water tank 20, so that water in the second water tank 20 does not flow back to the first water tank 10, when the acting force F applied to the valve element 2 is greater than 0, the first water tank 10 can automatically supply water to the second water tank 20 without applying additional power, and when the air pressure in the second water tank 20 is restored to the standard atmospheric pressure, the liquid level height in the second water tank 20 is greater than or equal to the liquid level height in the first water tank 10, so that the amount of water in the second water tank 20 can be controlled, and meanwhile, by disposing the valve element 2 in the valve cavity 11 in a manner of being capable of moving up and down, the influence of the gravity of the valve element 2 on the moving direction of the valve element 2 can be reduced, the displacement of the valve element 2 caused by the gravity of the valve element 2 can be avoided, which is beneficial to improving the one-way, thereby improving the reliability of the operation of the water tank assembly 100.

In some embodiments of the present invention, referring to fig. 5, the inner peripheral wall of the valve cavity 11 is formed with an annular step portion 12 extending along the circumferential direction of the valve cavity 11, the valve element 2 is located between the step portion 12 and the first interface 111, the valve element 2 cooperates with the step portion 12 to cut off the valve cavity 11, when F is reverse (F < 0), F pushes the valve element 2 to a direction close to the step portion 12, so that the valve element 2 cooperates with the step portion 12 to cut off the valve cavity 11; when F is in the forward direction (F > 0), F pushes the valve element 2 in a direction away from the step portion 12, so that the valve element 2 moves in a direction away from the step portion 12, and the valve element 2 is disengaged from the step portion 12 to enable the one-way valve 30 to be conducted in one direction, and the first water tank 10 automatically supplies water to the second water tank 20. Of course, the present invention is not limited to this, and at least a part of the peripheral wall of the valve cavity 11 may be gradually reduced in the direction from the second joint 1121 to the first joint 1111, and the valve core may be engaged with a part of the peripheral wall of the valve cavity 11 having a smaller flow area to cut off the valve cavity 11.

In the description of the present invention, it is to be understood that the terms "center", "length", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be considered as limiting.

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. The PTC heater has the outstanding characteristic of safety performance, and the phenomenon of reddening on the surface of the electric heating tube heater can not be generated under any application condition, so that potential safety hazards such as scalding and fire hazards are avoided.

In some examples, the density of the cartridge 2 is the same as the density of water, so F_{Floating body}And 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 of the heating member is stopped,if the exhaust valve is not opened in advance, the steam is condensed, at which point 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.

It can be understood that when F is less than 0, the valve core 2 is stopped to the abutting line 1233, and the deformation amount of the valve core 2 can be increased under the same pressure, which is beneficial to improving the sealing effect between the valve core 2 and the sealing matching part 123, thereby ensuring the sealing performance of the check valve 30 on the occasion with low fluid pressure and being beneficial to improving the working reliability of the water tank assembly 100.

Of course, as shown in fig. 12, the present invention is not limited thereto, the end of the first annular surface 1231 away from the first step surface 121 and the end of the second annular surface 1232 away from the first step surface 121 may also be transited through the abutting arc surface 1234, thereby being beneficial to reducing the manufacturing difficulty of the sealing matching portion 123, and being beneficial to reducing the production cost.

In some alternative embodiments of the present invention, as shown in fig. 5, the surface of the valve element 2 engaged with the seal engaging portion 123 is a flat surface. Therefore, the valve core 2 has a simple structure, and the manufacturing difficulty of the valve core 2 is favorably reduced. For example, as shown in fig. 5, the valve core 2 includes a valve core bottom wall 21 and a valve core side wall 22, the lower end of the valve core side wall 22 is connected with the outer periphery of the valve core bottom wall 21, a lightening hole 23 is defined between the valve core side wall 22 and the valve core bottom wall 21, the central axis of the lightening hole 23 is collinear with the central axis of the valve core side wall 22, and the lower surface of the valve core bottom wall 21 is formed into a plane and is matched with the sealing matching part 123, it can be understood that, by providing the lightening hole 23, not only the weight of the valve core 2 can be reduced to reduce the production cost, but also when F < 0, the contact area between the liquid on the side of the valve core 2 adjacent to the second water tank 20 and the valve core 2 can be increased, so that the deformation amount of the valve core 2 can be increased under the same liquid pressure, the sealing effect between the valve core 2 and the sealing matching part, which is advantageous in improving the reliability of the operation of the water tank assembly 100.

Alternatively, as shown in fig. 10, the cross-sectional area of the seal-fitting portion 123 gradually decreases in the direction from the first port 111 to the spool 2. Note that a single-sided cross section obtained by cutting the plane of the center axis of the seal engagement portion 123 through the seal engagement portion 123 is a cross section of the seal engagement portion 123. When F is less than 0, the valve core 2 is stopped to the end, with the smaller cross-sectional area, of the sealing matching part 123, the deformation amount of the valve core 2 can be increased under the same pressure, and the sealing effect between the valve core 2 and the sealing matching part 123 is favorably improved, so that the sealing performance of the check valve 30 on occasions with low fluid pressure is ensured, and the working reliability of the water tank assembly 100 is favorably improved. For example, as shown in fig. 10, the seal-fitting portion 123 is formed in a substantially triangular shape in cross section.
