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.
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 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).
In some embodiments of the present invention, as shown in fig. 4 and 5, a part of the inner peripheral wall of the valve cavity 11 is formed as a tapered surface 11d, the valve core 2 is located between the tapered surface 11d and the second interface 112, and in a direction from the second interface 112 to the tapered surface 11d, the flow area of the valve cavity 11 at the tapered surface 11d is gradually reduced, and the sealing ring 22 abuts against the tapered surface 11d to cut off the valve cavity 11.
Therefore, the reliability of matching of the valve core 2 and part of the inner wall of the valve cavity 11 is improved, the radial sealing effect of the valve cavity 11 can be realized by the sealing ring 22, when the acting force F borne by the valve core 2 is less than 0, the water in the second water tank 20 can be ensured not to flow back to the first water tank 10, and the reliability of the work of the water tank assembly 100 is improved. For example, in the top-down direction, the flow area of the valve chamber 11 at the tapered surface 11d gradually decreases.
Alternatively, the tapered surface 11d is formed in an isosceles trapezoid in cross section. Here, a unilateral section obtained by cutting the tapered surface 11d through a plane passing through the center axis of the tapered surface 11d is referred to as a cross section of the tapered surface 11 d.
Alternatively, as shown in fig. 4 and 5, the seal ring 22 is formed in a circular ring shape, and the cross section of the seal ring 22 is formed in a circular shape, wherein a single-sided section obtained by cutting the seal ring 22 through a plane of the central axis of the seal ring 22 is referred to as a cross section of the seal ring 22. Therefore, the structure is simple, linear sealing between the sealing ring 22 and the conical surface 11d can be realized, the radial sealing effect of the sealing ring 22 on the valve cavity 11 is further improved, and the working reliability of the water tank assembly 100 is further improved.
Alternatively, as shown in fig. 4, the valve core body 21 is provided with a guide groove 212, the check valve 30 further includes a guide portion 3, one end of the guide portion 3 is mounted to the valve seat 1, the other end of the guide portion 3 extends into the guide groove 212 and is in sliding fit with the valve core 2, when the acting force F applied to the valve core 2 is less than 0, the other end of the guide portion 3 is spaced from the inner bottom wall 2121 of the guide groove 212, and simultaneously the valve core 2 moves until the sealing ring 22 abuts against a part of the inner wall of the valve cavity 11 to cut off the valve cavity 11. It can be understood that when the valve core 2 is subjected to the acting force F > 0, the valve core 2 moves and makes the other end of the guide portion 3 engage with the inner bottom wall 2121 of the guide groove 212, and at the same time, the sealing ring 22 disengages from the valve cavity 11 to conduct the valve cavity 11 in one direction and the first water tank 10 automatically supplies water to the second water tank 20.
