The embodiment is as follows:

referring to fig. 1-3, the present invention provides a technical solution: a filter cartridge for a filter, comprising:

the filter comprises a hollow outer cylinder body 1 with an opening at the upper part, wherein a partition plate 2 is arranged at the lower side in the outer cylinder body 1, the edge of the partition plate 2 is hermetically connected with the inner wall of the outer cylinder body 1, and the partition plate 2 divides the outer cylinder body 1 into an upper filter cavity and a lower pressure cavity;

wherein, set up active carbon 3 in the filter chamber, active carbon 3 is granular structure, also can be the active carbon stick structure of bar-shaped. An air bag 4 is arranged in the pressure cavity; in order to replace the air bag 4 conveniently, the filter cavity and the pressure cavity adopt a split structure, and the filter cavity and the pressure cavity are connected in a threaded mode. When the pressure chamber is screwed off the filter chamber, the bladder 4 can be removed and replaced with a new bladder 4.

The upper portion opening part of outer barrel 1 is provided with the closing cap, and it has inlet tube 6, outlet pipe 7 and pure water pipe 5 to peg graft on the closing cap, inlet tube 6, outlet pipe 7 and the inside intercommunication of filter chamber, the bottom of pure water pipe 5 is pegged graft on division board 2, and pure water pipe 5 and the inside intercommunication of pressure chamber, and the closing cap passes through the upper portion opening part of screw thread detachable connection at outer barrel 1.

As shown in FIG. 3, the water outlet pipe 7 is connected with a tap, the water inlet pipe 6 is connected with one water inlet end (i.e. the pure water end filtered by the filtering membrane), and the pure water pipe 5 is connected with the water inlet pipe 6 through the check valve 8, so that the pure water in the water inlet pipe 6 can enter the pure water pipe 5 through the check valve 8, as shown in FIG. 3, the electromagnetic valve 9 is installed on the external pipeline of the pure water pipe 5.

The joint of the water inlet pipe 6, the water outlet pipe 7 and the pure water pipe 5 with the sealing cover is connected through a quick-connection plug, and the joint is sealed to prevent air leakage. The outer cylinder 1 is made of plastic, stainless steel or aluminum alloy.

The pure water filtered by the preorder filtering membrane enters the outer cylinder body 1 through the water inlet pipe 6, the active carbon 3 absorbs the entered pure water to remove peculiar smell, and the tap is opened, so that the pure water is always output through the water outlet pipe 7. When the tap is closed, pure water is still generated, the generated inlet water enters the pure water pipe 5 through the check valve 8, and the check valve 8 is set to be opened when the pressure exceeds 0.5 kg. As the pure water in the pure water pipe 5 increases, the pure water enters the pressure chamber downward, the air bag 4 contracts in volume by the pressure of the pure water (as shown in fig. 2), and a closing air pressure value or a closing hydraulic pressure value is set in advance, and accordingly, an air pressure sensor for detecting the air pressure in the air bag 4 is provided in the air bag 4 or a hydraulic pressure sensor for detecting the hydraulic pressure in the pure water pipe 5 is provided in the pure water pipe 5. When the air pressure sensor detects that the air pressure value in the air bag 4 reaches a set closing air pressure value or the hydraulic pressure sensor detects that the hydraulic pressure value in the pure water pipe 5 reaches a closing hydraulic pressure value, the water filtering stage in the prior step is stopped.

As shown in fig. 3, the outlet of the solenoid valve 9 is connected to the flushing port of the pre-filter device through a pipeline, when the solenoid valve 9 is opened, the pure water in the pure water pipe 5 and the pressure chamber is output from the outlet of the solenoid valve 9 under the elastic force of the air bag 4 (when the air bag 4 is compressed, the internal air pressure is large), and the pre-filter device (such as an RO reverse osmosis membrane and a nanofiltration membrane) is flushed. At this time, the air pressure value in the air bag 4 detected by the air pressure sensor is gradually smaller than the set closing air pressure value or the hydraulic pressure value in the pure water pipe 5 detected by the hydraulic pressure sensor is gradually smaller than the closing hydraulic pressure value along with the outflow of the pure water, and the filtering device is not continuously started to work at this time, which is regarded as a normal step after the water consumption is stopped.
