The first cleaning mechanism includes a drain 41, a suction nozzle 42 and a debris polarization assembly.
The sewage drain pipe 41 is arranged in the coarse filter cylinder 3, the upper end of the sewage drain pipe 41 is sealed and connected with a transmission shaft 411, and the transmission shaft 411 rotates to penetrate through the top of the shell 1; the transmission shaft 411 is in transmission connection with a driving motor (not shown in the figure) so as to drive the sewage drain 41 to rotate; the lower end of the blow-down pipe 41 rotates to penetrate through the bottom of the shell 1 and is connected with a rotary joint 412; the swivel joint 412 may be connected to an external stationary pipe and suction apparatus (not shown) to facilitate the drainage.
One end of the dirt suction nozzle 42 is connected to the drain pipe 41, and the other end is disposed near the inner side of the coarse filter cartridge 3.
The "close to the inner side of the coarse filter cartridge 3" means that a certain gap is left between the dirt suction nozzle 42 and the inner side of the coarse filter cartridge 3, and the dirt suction nozzle 42 and the inner side of the coarse filter cartridge 3 are not in direct contact.
The impurity polarization component is used for transferring electrons to the coarse filter cylinder 3 when the water pressure difference between the liquid outlet 12 and the liquid inlet 11 reaches a preset value, so that tiny impurities positioned on the inner side of the coarse filter cylinder 3 and nearby are polarized, and the tiny impurities are gathered and attached on the inner side of the coarse filter cylinder 3.
When the water pressure difference between the liquid outlet 12 and the liquid inlet 11 reaches a predetermined value, it is indicated that the rough filter cylinder 3 needs to be cleaned, at this time, the fine impurities near the inner side of the rough filter cylinder 3 are polarized by the impurity polarization component, so that the fine impurities are gathered and attached to the inner side of the rough filter cylinder 3 (the fine impurities on the outer side of the rough filter cylinder 3 are gathered and attached to the outer side of the rough filter cylinder 3), and then the driving motor drives the transmission shaft 411 and the drain pipe 41 to rotate, so that the sewage suction nozzle 42 rotates and sucks the impurities on the inner side of the rough filter cylinder 3 by utilizing the negative pressure generated by the external suction equipment, thereby cleaning, dredging and draining the inner side of the rough filter cylinder 3 are realized.

The electronic drum 437 is made of a conductive material and transmits electrons to the coarse filter cartridge 3.
The working principle of the sundry polarization component is as follows: when the rotation shaft 434 rotates, the insulating connector 435 and the conductive rod 436 rotate with it, and the conductive rod 436 generates induced electromotive force by cutting the magnetic induction line between the first permanent magnet plate 432 and the second permanent magnet plate 433, so that electrons are collected at the end of the conductive rod 436 and transferred to the coarse filter cartridge 3 by conduction of the electron middle drum 437, thereby polarizing fine impurities located at and near the inside of the coarse filter cartridge 3, and collecting and attaching the fine impurities on the inside of the coarse filter cartridge 3 (fine impurities located at the outside of the coarse filter cartridge 3 are collected and attached on the outside of the coarse filter cartridge 3).

The detection pipe 51 is provided with a water inlet leading-in head 511, a water outlet leading-in head 512, a water inlet water discharge head 513 and a water outlet water discharge head 514; the water inlet leading-in head 511 is connected with a liquid inlet 11 on the shell 1; the outlet water introducing head 512 is connected to the outlet 12 of the casing 1.
The partition plate 52 is provided in the detection pipe 51 and separates the detection pipe 51 into a water intake pressure detection passage 515 and a water discharge pressure detection passage 516 which are independent of each other; both the water inlet leading-in head 511 and the water inlet discharging head 513 are connected with the water inlet pressure detection channel 515; the outlet water introduction head 512 and the outlet water discharge head 514 are connected to an outlet water pressure detection passage 516. The partition plate 52 is provided with a connection passage 521.
The movable sealing plate 53 is slidably disposed in the connection passage 521 for partitioning the intake pressure detecting passage 515 and the discharge pressure detecting passage 516.
The working principle of the water inlet and outlet pressure detection mechanism is as follows: leading water inlet and water outlet of the high-precision filter element into two mutually independent channels (namely a water inlet pressure detection channel 515 and a water outlet pressure detection channel 516) in one pipeline (namely a detection pipe 51), and reflecting the water inlet and water outlet pressure difference condition of the high-precision filter element through the movement condition of a movable sealing plate 53; specifically, when the movable sealing plate 53 moves to the water outlet pressure detecting channel 516 by a predetermined distance, it indicates that the water outlet pressure is too low, and there is a blockage in the device, at this time, the debris polarization assembly can be operated, and the drain pipe 41 and the dirt suction nozzle 42 can be rotated, so that the inner side of the coarse filter cartridge 3 is cleaned and dredged.

In this embodiment: the accommodating box 431 is disposed on the detecting tube 51, one end of the rotating shaft 434 is connected with the movable sealing plate 53, and the other end of the rotating shaft penetrates the detecting tube 51 and then penetrates the first permanent magnet plate 432. The partition plate 52 is connected with a shielding box 541 through a supporting rod 542; the rotating shaft 434 is provided with a driving blade 543, and the driving blade 543 is positioned in the water outlet pressure detection channel 516 and can follow the movement of the sealing plate 53 to enter and exit the shielding box 541; specifically, when the movable sealing plate 53 moves to the water outlet pressure detecting channel 516 by a predetermined distance, the driving blade 543 moves to the outside of the shielding box 541, at this time, the driving blade 543 can drive the rotating shaft 434 and the conductive rod 436 to rotate under the driving of the water flow (when the driving blade 543 is located in the shielding box 541, the driving blade 543 does not rotate due to the water flow), so as to realize the linkage between the water inlet and outlet pressure detecting mechanism and the sundry polarizing component.
In order to improve the cleaning effect on the inner side of the coarse filter cylinder 3, the end part of the dirt suction nozzle 42 can be connected with a telescopic head 421 which is communicated with the dirt suction nozzle 42 in a sliding way; a spring 422 is connected between the telescopic head 421 and the dirt suction nozzle 42; the end of the extension head 421 facing the coarse filter cartridge 3 is provided with extension head bristles 423.
During the rotation of the suction nozzle 42 with the drain pipe 41, the telescopic head 421 moves towards the inner side of the coarse filter cartridge 3 under the action of centrifugal force, the bristles 423 of the telescopic head clean the sundries on the inner side of the coarse filter cartridge 3, and the scanned sundries are sucked into the suction nozzle 42 and the drain pipe 41 through the telescopic head 421 which is closer to the inner side of the coarse filter cartridge 3 (relative to the suction nozzle 42), so that the inner side of the coarse filter cartridge 3 is better cleaned and dredged, and the sundries are effectively discharged.
In combination with the above, the present embodiment has at least the following advantages:

In this embodiment, in order to rotate the first brush roller 61 around the axis of the coarse filter cartridge 3 and the second brush roller 62 around the axis of the fine filter cartridge 2, the second cleaning mechanism further includes a support plate 63, the support plate 63 being provided inside the bottom wall of the housing 1, one end of the support plate 63 being fixed to the drain pipe 41, the support plate 63 being rotatable with the drain pipe 41; the first brush roller 61 and the second brush roller 62 are mounted on the carrier plate 63, and the casing 1 has the annular groove 13 for avoiding the first brush roller 61 and the second brush roller 62.
Through the setting of the bearing plate 63, the first brush roller 61, the second brush roller 62 and the sewage drain 41 can synchronously rotate, so that when the water pressure difference between the liquid outlet 12 and the liquid inlet 11 reaches a preset value, the inner side of the fine filter cylinder 2 and the outer side of the coarse filter cylinder 3 are cleaned, and the cleaned sundries are finally discharged by the sewage suction nozzle 42 and the sewage drain 41.
Example 3
This example is a further improvement over example 2.
In the first aspect, referring to fig. 1 to 5, in the present embodiment, the first brush roller 61 and the second brush roller 62 are in transmission connection through the reversing assembly, and the weight of the first brush roller 61 is smaller than that of the second brush roller 62, and the first brush roller 61 and the second brush roller 62 are configured to slide only along the radial direction of the drain pipe 41 during the rotation of the drain pipe 41, so that the centrifugal force applied to the first brush roller 61 is smaller than that applied to the second brush roller 62 during the rotation of the drain pipe 41, and the second brush roller 62 can drive the first brush roller 61 to move during the contact with the inner side of the fine filter cartridge 2, so that the first brush roller 61 contacts with the outer side of the coarse filter cartridge 3, thereby achieving a better cleaning effect.
The first brush roller 61 and the second brush roller 62 do not rotate around their own axes, which is more advantageous for cleaning foreign matters.
Specifically, the support plate 63 is provided with a guide groove 631 disposed along the radial direction of the sewage drain 41, and the first brush roller 61 and the second brush roller 62 are slidably connected to the guide groove 631, so that only the radial direction of the sewage drain 41 is slid during the rotation of the sewage drain 41.
The reversing assembly comprises a compression spring 641, a first toothed plate 642, a reversing gear 643 and a second toothed plate 644 which are in transmission connection in sequence.
The first toothed plate 642 is fixed to the first brush roller 61, the second toothed plate 644 is fixed to the second brush roller 62, and the reversing gear 643 is provided between the first toothed plate 642 and the second toothed plate 644; one end of the compression spring 641 is connected to the second brush roller 62, and the other end is connected to the support plate 63.
Before the drain pipe 41 rotates, the first brush roller 61 is not contacted with the outer side of the coarse filter cartridge 3, and the second brush roller 62 is not contacted with the inner side of the fine filter cartridge 2, so that the water flux of the coarse filter cartridge 3 and the fine filter cartridge 2 is not affected; after the drain pipe 41 rotates, through the arrangement of the reversing assembly, the second brush roller 62 can drive the first brush roller 61 to move in the process of contacting with the inner side of the fine filter cylinder 2, so that the first brush roller 61 contacts with the outer side of the coarse filter cylinder 3, and the outer side of the coarse filter cylinder 3 is cleaned.
In a second aspect, referring to fig. 1 to 5 and in combination with the foregoing, the present embodiment provides an anti-blocking method for the high-precision filter element, including the following steps:
step S1, detecting a water pressure difference value between a liquid inlet 11 and a liquid outlet 12 of a high-precision filter element;
step S2, when the water pressure difference reaches a preset value, fine impurities near the coarse filter cylinder 3 are gathered and attached to the coarse filter cylinder 3, and meanwhile, the sewage drain pipe 41 drives the sewage suction nozzle 42, the first brush roller 61 and the second brush roller 62 to synchronously rotate;
during the rotation of the dirt sucking nozzle 42, the telescopic head 421 moves to the inner side of the coarse filter cylinder 3 under the action of centrifugal force, the bristles 423 of the telescopic head clean the sundries on the inner side of the coarse filter cylinder 3, and the sundries are sucked into the dirt sucking nozzle 42 through the telescopic head 421 which is closer to the inner side of the coarse filter cylinder 3;
the second brush roller 62 can contact with the inner side of the fine filter cylinder 2 in the rotating process and drive the first brush roller 61 to move, so that the first brush roller 61 contacts with the outer side of the coarse filter cylinder 3; debris located between the fine filter cartridge 2 and the coarse filter cartridge 3 is discharged through the dirt pickup nozzle 42.
Finally, it should be noted that: the above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made to the present invention by those skilled in the art, and the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without collision. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
