When the pressure difference between the first cavity 26 and the second cavity 27 is detected by the first pressure sensor and the second pressure sensor respectively, the controller controls the control valve 28 to open the blowoff valve 29 and communicate the water inlet port 23 with the second cavity 27 when the pressure difference reaches a preset value, the washing water flows from the second cavity 27 to the first cavity 26 through the filter material 22, so that the back washing function is realized, the cotton wool or other sundries trapped by the filter material 22 are flushed out and flow out through the blowoff port 24. At this time, the control valve 28 may also isolate the water outlet port 25 from the second chamber 27, and the control valve 28 may not need this function for cost reasons, because the blowdown valve 29 is opened, the first chamber 26 is communicated with the outside, and the pressure of the first chamber 26 is lower than the water pressure in the second connection pipe 32, so the washing water in the second chamber 27 will still flush the filter material 22 and flow to the first chamber 26.

Of course, the user can also select the direct washing function of the filter 20, that is, when the pressure difference reaches a preset value, the controller controls the control valve 28 to open the blowdown valve 29, and the water inlet port 23 communicates with the first chamber 26 to directly wash the inner peripheral wall of the filter material 26.

Referring also to fig. 3, a schematic diagram of a second construction of the filter 20 is shown, differing from the first construction in that: the second chamber 27 is located in the filter material 22, the first chamber 26 is located between the first casing 21 and the filter material 22, and a wiper 221 is disposed in the first casing 21, the wiper 221 having a wiping surface pressed against the outer peripheral surface of the filter material 22. It should be noted that, in the process of implementing the back flushing of the filter 20, the washing water flows from the second chamber 27 to the first chamber 26 through the filter material 22 to flush the plugs on the outer peripheral surface of the filter material 22, and at the same time, the first housing 21 can be rotated to drive the scraping surface of the scraper 221 to scrape the outer peripheral surface of the filter material, so as to further clean the filter material, and then the washing water flows from the first chamber 26 to the sewage outlet 24.

In the second structure of the filter 20, a person skilled in the art needs to connect the first housing 21 and the control assembly in a rotary sealing manner, which is the prior art and will not be described in detail. In addition, the bottom wall and the peripheral wall of the first casing 21 may be connected to each other in a rotary seal manner, and the wiper 221 may be fixed to the bottom wall of the first casing 21, thereby achieving the wiping function.

In the two structures of the filter 20, the controller is a component for realizing the automatic operation back washing function and the direct washing function of the filter 20, and of course, the controller can be changed into manual control according to the use scene, namely, the control valve 28 and the drain valve 29 are manually controlled.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art.
