Before using water, can open sealed lid from the opening when packing into water to make first cavity 11 and second cavity 12 all be in the intercommunication atmospheric state, thereby guarantee that the liquid level height of first cavity 11 and second cavity 12 is unanimous, the air pressure of first cavity 11 and second cavity 12 liquid level top is atmospheric pressure this moment, after adorning water, close sealed lid with the opening again in order to seal second cavity 12, thereby make second cavity 12 be in airtight state. Wherein the content of the first and second substances,
the method for detecting the water consumption of the equipment comprises the following steps:
s1: acquiring the liquid level height difference L1 between the second cavity 12 and the first cavity 11 after water consumption;
initially, the liquid level heights of the first cavity 11 and the second cavity 12 are consistent, after the water is sucked away from the first cavity 11 by the water suction pipe 2, the liquid level heights in the first cavity 11 and the second cavity 12 both decrease, because the second cavity 12 is arranged in a sealing manner, the air pressure in the second cavity 12 decreases after the liquid level in the second cavity 12 decreases, the liquid in the first cavity 11 enables the water to enter the second cavity 12 from the communication position between the liquid and the second cavity 12 under the action of atmospheric pressure and lift up the liquid above the second cavity 12, so that the liquid level of the second cavity 12 is higher than the liquid level of the first cavity 11, and a liquid level height difference L1 is formed between the liquid level in the second cavity 12 after the water is used and the liquid level in the second cavity 12;
s2: acquiring the air expansion height L2 of the second cavity 12 after water consumption;
the second cavity 12 is sealed, and initially, the liquid level in the second cavity 12 before water consumption is higher than that after water consumption, so that the air volume in the second cavity 12 before water consumption is small, when the liquid level in the second cavity 12 drops, the air volume in the second cavity 12 becomes large, the same amount of air expands, and the air expansion height L2 is the air height increased after expansion on the basis of the original air height;
s3: the water consumption of the water reservoir 1 is calculated according to the air expansion height L2 and the liquid level difference L1.
According to the sum of the height of air expansion in the second cavity 12 after water consumption and the liquid level height difference between the second cavity 12 and the first cavity 11 after water consumption, the water consumption can be obtained, one of the height of water occupying the water storage device 1, the weight of water and the volume of water can be used as the measurement, and when the height L0 is used for representing, the height value of air expansion and the liquid level height difference are directly added; when the volume expression is adopted, the calculation is carried out by using the formula V ═ SL1+ S 'L2, wherein S is the cross-sectional area of the first cavity 11, and S' is the cross-sectional area of the second cavity 12; when the expression is weight, it is calculated by using the formula M ═ V ρ.

s11: acquiring a first air pressure P0 of the second cavity 12 before water consumption and a second air pressure P1 of the second cavity 12 after water consumption;
before water is used, the liquid level heights of the first cavity 11 and the second cavity 12 are consistent, at the moment, a first air pressure P0 above the liquid level in the second cavity 12 is the same as a third air pressure above the liquid in the first cavity 11 and is atmospheric pressure, and the second air pressure P1 can be directly read by a pressure sensor 3 arranged at the top of the second cavity 12 in a detection device;
s12: calculating a liquid pressure P2 generated by a liquid level height difference L1 according to the first air pressure P0 and the second air pressure P1;
the liquid pressure P2 generated by the liquid level height difference L1 is calculated by the formula P0 ═ P1+ P2;
s13: the liquid level difference L1 is calculated from the liquid pressure P2. The liquid level difference L1 can be calculated by the formula P2 ═ ρ gL1, where ρ is the density constant of water and g is the gravity coefficient constant.
In the present embodiment, the liquid level height difference L1 is determined by obtaining the first air pressure P0 of the second chamber 12 before water is used and the second air pressure P1 of the second chamber 12 after water is used, based on the fact that the first air pressure P0 of the second chamber 12 before water is equal to the sum of the second air pressure P1 of the second chamber 12 after water is used and the liquid pressure P2 of the second chamber 12 after water is used.

s22: calculating the air expansion volume V1 of the second cavity 12 after water consumption according to the air volume V0, the first air pressure P0 and the second air pressure P1;
because the second chamber 12 is sealed, the air content in the second chamber 12 is the same before and after the water is used, according to the krebs equation:
P0V0 ═ RT (M/M), P1(V0+ V1) ═ M/M) RT where M is the mass of the gas, M is the molar mass of the gas, R is the universal constant of the gas, and T is the temperature of the gas, so in the application of the embodiments of the invention, (M/M) RT ═ constant, so V1 can be calculated according to the formula P0V0 ═ P1(V0+ V1);
s23: from the air expansion volume V1, an air expansion height L2 was calculated.
From the formula V1 — S' L2, the air inflation height L2 of the second chamber 12 after water consumption can be determined.
The present embodiment finds that the product of the first air pressure P0 of the second chamber 12 before water use and the air volume V0 is equal to the product of the second air pressure P1 of the second chamber 12 after water use and the total air volume (i.e., the sum of the air volume V0 before expansion and the expanded air volume V1) according to the lambert's equation, thereby finding the air expansion height L2 of the second chamber 12 after water use.
