Preferably, an ultraviolet lamp 84 is disposed in the oil-water separator 80, and may be preferably disposed in the third chamber 83, or may be disposed in the first chamber 81 or the second chamber 82, the washing liquid is irradiated by the ultraviolet lamp 84, and the energy of the ultraviolet photons breaks the DNA structures of various viruses, bacteria and other pathogens in the water body, mainly breaks various structural bonds in the DNA or performs photochemical polymerization, for example, dimerizes THYMINE in the DNA, so that various viruses, bacteria and other pathogens lose their replication and reproduction capability, thereby achieving the sterilization effect.

When the pressure difference between the first chamber 26 and the second chamber 27 is detected by the first pressure sensor and the second pressure sensor, respectively, the controller controls the control valve 28 to open the drain valve 29 and communicate the water inlet port 23 with the second chamber 27, and the washing liquid flows from the second chamber 27 to the first chamber 26 through the filter material 22, so as to realize the back washing function, and flush out the residues or other impurities retained by the filter material 22 and flow out through the drain port 24. At this time, the control valve 28 may also isolate the water outlet port 25 from the second chamber 27, but for cost reasons, the control valve 28 may not need this function 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 less than the water pressure in the second connection pipe 32, so that the washing liquid in the second chamber 27 can still flush the filter material 22 and flow to the first chamber 26.

Of course, the user can also select the direct flushing function of the cleaner 20, i.e. 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 flush the inner peripheral wall of the filter material 26.

With additional reference to fig. 3, a schematic diagram of a second configuration of the slag separator 20 is shown, differing from the first configuration in that: the second chamber 27 is located in the filter material 22, the first chamber 26 is located between the casing 21 and the filter material 22, and a wiper 221 having a wiping surface which is pressed against the outer peripheral surface of the filter material 22 is arranged in the casing 21. It should be noted that, during the process of implementing the back flushing of the slag remover 20, the washing liquid 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 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 liquid flows from the first chamber 26 to the sewage outlet 24.

In the second configuration of the slag remover 20, the skilled person needs to connect the housing 21 and the control assembly in a rotary sealing manner, which is prior art and will not be described in detail. Further, the bottom wall and the peripheral wall of the housing 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 housing 21, thereby achieving a wiping function.

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.
