For the ease of the pressure difference inside and outside control water bag, in a specific example, water bag flexible is arranged in pressurized tank, pressurized tank
With air inlet and exhaust outlet, water bag has the mouth of a river of crossing for inflow and outflow, and is connected with water lines are crossed.Certainly, another
In one specific example, water bag exposed can also be arranged in an atmosphere.It is right hereinafter by by taking the water bag being arranged in pressurized tank as an example
The method for controlling water level of water purifier water bag is described in detail.It certainly, can be to water level control for the water bag being arranged in other ways
Method processed is adjusted correspondingly, and controls the water level in water bag, details are not described herein.Water bag passed through the mouth of a river and was connected to outside,
Gas pressure intensity in water bag corresponds in water bag the gas pressure intensity in the not space occupied by water purification, i.e., water purification liquid level in water bag
On gas pressure, can be obtained by pressure sensor.Gas pressure intensity when water bag is arranged in pressurized tank, outside water bag
For the gas pressure intensity in pressurized tank, the i.e. pressure of gas between the inner wall of pressurized tank and the outer wall of water bag.
Step S200, the water level in water bag is determined according to the gas pressure intensity in water bag；
When the mouth of a river excessively of water bag is in closed state, the gas pressure intensity in water bag is related to its water level, in water bag
Water purification increases, i.e., the rising of water level in water bag, the portion gas on water purification liquid level in water bag is compressed, in water bag
Gas pressure intensity in water bag water level rise and increase.Further, the water level in the gas pressure intensity and water bag in water bag
Between specific functional relation can be obtained by way of experimental calibration or theoretical calculation, thus according to the gas pressure in water bag
By force, that is, it can determine the water level in water bag.
Step S300, when the water level in water bag is greater than the first preset water level, control water bag water outlet.
Wherein, the first preset water level corresponds to the warning line of water bag, and the water level in water bag is greater than the first preset water level
When, show that water bag has been in higher load condition at this time, causes water bag because of inside water pressure in order to avoid water level further increases
Excessive and burst, control water bag water outlet is to reduce the load of water bag, to extend the service life of water bag.The water outlet of water bag can lead to
The gas pressure intensity difference crossed inside and outside control water bag changes and realizes.When the gas pressure intensity outside water bag is super compared to the gas pressure intensity in water bag
Out when setting value, water bag is squeezed, and is crossed water lines and is turned on, and the water purification in water bag passed through mouth of a river outflow, hereinafter will also

In the present invention, by obtaining the gas pressure intensity in water bag, the water in water bag is determined according to the gas pressure intensity in water bag
Position, when the water level in water bag is greater than the first preset water level, control water bag water outlet, so that the water level in water bag is adjusted,
It avoids water bag from bursting because water purification therein is excessive, extends the service life of water bag.Meanwhile the gas pressure intensity obtained in water bag can
It is realized by the pressure sensor etc. not contacted directly with water purification, the pollution so as to avoid water level detecting to water purification in water bag.
In the second embodiment of the present invention, as shown in Fig. 2, step S200 includes:
Step S210, it is pre- to be less than or equal to first for the absolute value of the difference of the gas pressure intensity in the adjacent water bag obtained twice
If when pressure difference, calculating the water level in water bag according to the current detection value of the gas pressure intensity in water bag.
Wherein, the adjacent time interval for obtaining the gas pressure intensity in water bag twice is less than or equal to the first preset duration.When
Water level in water bag be in variation or variation soon when, due to the influence of water flow, gas pressure intensity in water bag there may be
Certain fluctuation causes the accuracy of water level detecting to decline.In the present embodiment, by comparing in the adjacent water bag obtained twice
Gas pressure intensity absolute value of the difference, judge whether gas pressure intensity has been in stable state.When in the adjacent water bag obtained twice
Gas pressure intensity absolute value of the difference be less than or equal to the first default pressure difference when, show that the gas pressure intensity in water bag is stable,
The water level in water bag is calculated according to the current detection value of gas pressure intensity.In order to avoid because the adjacent time interval detected twice it is excessive
Cause water water level to generate biggish variation, and cause even if stable level, the gas pressure intensity in the adjacent water bag obtained twice is poor
Absolute value also greater than the first default pressure, the adjacent time interval for obtaining the gas pressure intensity in water bag twice is set and is less than or waits
In the first preset duration.Wherein, the first preset duration is related to the inflow and outflow rate of water bag, to exclude water bag water inlet and go out
Interference of the SEA LEVEL VARIATION that water generates to stable level is judged.It, can be every certain when obtaining the gas pressure intensity in water bag
Time interval obtains, and can also obtain in real time, and the gas pressure intensity chosen in qualified water bag is compared.
In the third embodiment of the present invention, as shown in figure 3, step S100 includes:

Strong difference is realized.When the gas pressure intensity in water bag exceeds setting value compared to the gas pressure intensity outside water bag, water purification by the mouth of a river into
Enter in water bag.
Third preset water level corresponds to the desired level of water in water bag, and third preset water level is slightly less than the first preset water level.Work as water
When water level in bag is greater than third preset water level, causes water bag load larger in order to avoid the water level in water bag continues to increase, control
Water bag processed stops water inlet.However, water bag fails to stop water inlet in time if due to system failure etc., its volume is still at this time
Constantly become larger.Therefore, in order to avoid water bag reaches the limit of deformation and is bursting at the collision, when the water level in water bag is greater than the first default water
When position, i.e. warning line, control water bag water outlet.In order to avoid the waste of water resource, preset when the water level in water bag is in first
When between water level and third preset water level, water bag can not need the water in discharge water bag in tolerance range still in deformation.
In the fifth embodiment of the present invention, as shown in figure 5, the method for controlling water level of water purifier water bag further includes following step
It is rapid:
Step S610, when water bag is intake, add up the continuum micromeehanics duration of water bag；
Step S620, when continuum micromeehanics duration reaches third preset duration, control water bag stops water inlet；
Step S630, continuum micromeehanics duration is reset.
By comparing the continuum micromeehanics duration and third preset duration of water bag, when continuum micromeehanics duration, which reaches third, to be preset
When long, control water bag stops water inlet, i.e., stops water inlet by the gas pressure intensity difference etc. inside and outside control water bag to control water bag.Its
In, third preset duration is six to eight hours, when reaching the third preset duration, it is generally recognized that water bag is in full water shape
State stops water inlet in order to avoid water bag is burst, causes water bag not stop to burst into water to avoid the gas pressure intensity detection failure in water bag.
Further, in the sixth embodiment of the present invention, as shown in fig. 6, after step S610, water purifier water bag

In the present embodiment, it is contemplated that the water when the continuum micromeehanics duration of water bag reaches four preset durations, in water bag
Position can reach water level corresponding with the 4th preset duration, correspondingly, the gas pressure intensity in water bag can reach corresponding
Pressure.But when detection failure or water bag breakage occur, the gas pressure intensity in acquired water bag will be less than first
Default pressure, wherein the first default pressure is less than or equal to water corresponding with the water level after the 4th preset duration of continuum micromeehanics
Gas pressure intensity in bag.At this point, being unable to control water bag by the gas pressure intensity in water bag stops water inlet, therefore alarm signal is generated,
