[0004] 2. The water stored in the pressure clean water bucket cannot be used up before the water is produced. The "old water" in the bucket is not used up, and the newly made "new water" enters the bucket again. There is always "old water" made a long time ago. "Old water" stays in the water for a long time, which is easy to breed bacteria and affect water quality
[0005] 3. The water production interval is very short, and the frequent start of the booster pump will affect its service life
[0006] In addition, since the pressure switch is fixedly set at a certain position of the water inlet pipe of the pressure storage tank, once set, the setting value of the pressure switch cannot be changed, resulting in the maximum water storage capacity of the pressure storage tank is always fixed, which cannot be adjusted according to user needs. Water storage capacity adjustment

Embodiment Construction
[0016] Such as figure 1 As shown, the pressure water storage tank of the present invention includes a housing 100, an inner water storage bag 200 and an air bag 300 located in the housing 100, the air bag 300 is located below the water storage bag 200, and the top of the housing 100 has a water inlet and outlet 400. The water inlet and outlet 400 communicate with the water storage bag 200 . A pressure sensor 500 is installed in the airbag 200 . The pressure sensor 500 is connected with the computer box of the reverse osmosis water purifier. The above is the structure of the pressure water storage tank of the present invention. The working principle of the pressure water storage tank is as follows: the water storage capacity (volume of water) in the pressure water storage tank can be calculated by the gas pressure in the air bag of the pressure water storage tank. The formula is as follows:
[0017] V = ( ...

The invention discloses a pressure water storage tank, which comprises a shell, and a water storage bag and an air bag which are located in the shell, wherein the air bag is located in the lower part of the water storage bag, the shell is provided with an water inlet and a water outlet which are communicated with the water storage bag, and the air bag is internally provided with a pressure sensor. The pressure water storage tank can avoid the frequently starting of a water purifier, reduces the discharge of waste water and improves water quality, prolongs the service life of the machine and realizes that the water storage capacity can be freely adjusted and set.
Description
technical field [0001] The invention belongs to the technical field of household water purification equipment, and relates to a reverse osmosis water purifier, in particular to a pressure water storage tank of the reverse osmosis water purifier. Background technique [0002] At present, the pressure water storage barrels adopted by the reverse osmosis water purifier all set the water storage capacity of the pressure water storage barrels by setting a pressure switch on the water inlet pipeline. When the pressure in the pressure water tank is lower than the set value of the pressure switch, the reverse osmosis water purifier starts to produce water; when the pressure in the pressure tank reaches the set value, the reverse osmosis water purifier stops to produce water. As long as it is lower than the set value of the pressure switch of the pressure tank, the water purifier will start to produce water, which leads to the following defects in the actual use of the pressure stora...
