[0065] The working principle and use process of the present invention:

[0066] In the initial state, one end of the first connecting pipe 53 is flush with the end of the first water inlet pipe 21, and the other end of the first connecting pipe 53 is flush with the first through groove 51. At the same time, the first extrusion spring 58 inside the first connecting pipe 53 will squeeze the two first sealing plates 56 at the same time. At this time, the first guide ring 57 on the surface of one of the sealing plates will be inserted into the first water inlet pipe 21, and the first sealing plate 56 will be against the first water inlet pipe 21. At the same time, the first guide ring 57 on the surface of the other sealing plate will be inserted into the first through groove 51, and the first sealing plate 56 will be against the first through groove 51. At this time, the first water inlet pipe 21 and the second first through groove 51 will be sealed because of the two first sealing plates 56 in the first connecting pipe 53.

[0067] At this time, one end of the second connecting pipe 54 is flush with the end of the second water inlet pipe 22, and the other end of the second connecting pipe 54 is flush with the second through groove 52. At the same time, the second extrusion spring 513 inside the second connecting pipe 54 will squeeze the two second sealing plates 510 at the same time. At this time, the second guide ring 512 on the surface of one of the second sealing plates 510 will be inserted into the second water inlet pipe 22, and the second sealing plate 510 will be against the second water inlet pipe 22. At this time, the second guide ring 512 on the surface of the other second sealing plate 510 will be inserted into the second through groove 52, and the second sealing plate 510 will be against the second through groove 52. Because the first through groove 511 is opened in the middle of the two second sealing plates 510, the second water inlet pipe 22 and the second through groove 52 can be connected through the second connecting pipe 54;

[0068] At the same time, one end of the third connecting pipe 63 is flush with the end of the connecting pipe 32, and the other end of the third connecting pipe 63 is flush with the third through groove 61. At the same time, the third extrusion spring 69 inside the third connecting pipe 63 will squeeze the two third sealing plates 66 at the same time. At this time, the third guide ring 68 on the surface of one of the third sealing plates 66 will be inserted into the connecting pipe 32, and the third sealing plate 66 will be against the connecting pipe 32. At the same time, the third moving ring on the surface of the other third sealing plate 66 will be inserted into the third through groove 61, and the third sealing plate 66 will be against the third through groove 61. Because the second through groove 67 is opened in the middle of the two third sealing plates 66, the connecting pipe 32 and the third through groove 61 can be connected through the third connecting pipe 63;

[0069] At the same time, one end of the fourth connecting pipe 64 is flush with the end of the drain pipe 31, and the other end of the fourth connecting pipe 64 is flush with the fourth through groove 62. At the same time, the fourth extrusion spring 613 inside the fourth connecting pipe 64 will squeeze the two fourth sealing plates 611 at the same time. At this time, the fourth guide ring 612 on the surface of one of the sealing plates will be inserted into the drain pipe 31, and the fourth sealing plate 611 will be against the drain pipe 31. At the same time, the fourth guide ring 612 on the surface of the other sealing plate will be inserted into the fourth through groove 62, and the fourth sealing plate 611 will be against the fourth through groove 62. At this time, the drain pipe 31 and the second fourth through groove 62 will be sealed because of the two fourth sealing plates 611 in the fourth connecting pipe 64.

[0070] At this time, water is passed into the first water inlet pipe 21, and the water flows through the second water inlet pipe 22, the second connecting pipe 54 and the second through groove 52 to enter the bottom of the filter chamber 14, and then the water flows forward through the filter element 42 to enter the upper part of the filter chamber 14, thereby completing the filtration of the water, and then the water flows through the third through groove 61, the third connecting pipe 63 and the connecting pipe 32 to enter the interior of the atomizing nozzle 33 and be discharged through the atomizing nozzle 33;

[0071] When the filter element 42 needs to be backwashed, the rotating ring 13 needs to be rotated 180 degrees. At this time, the rotating ring 13 will drive the first connecting pipe 53 to rotate synchronously through the first connecting rod 55. At this time, one end of the first connecting pipe 53 will be flush with the second water inlet pipe 22, and the other end of the first connecting pipe 53 will be flush with the second through groove 52, and the second water inlet pipe 22 and the second through groove 52 will be sealed respectively by two first sealing plates 56;

[0072] At the same time, the rotating ring 13 will drive the second connecting pipe 54 to rotate synchronously through the second connecting rod 59. At this time, one end of the second connecting pipe 54 will be flush with the first water inlet pipe 21, and the other end of the second connecting pipe 54 will be flush with the first through groove 51, so that the first water inlet pipe 21 and the first through groove 51 are connected through the second connecting pipe 54.

[0073] At the same time, the rotating ring 13 will drive the third connecting pipe 63 to rotate synchronously through the third connecting rod 65. At this time, one end of the third connecting pipe 63 will be flush with the drain pipe 31, and the other end of the third connecting pipe 63 will be flush with the fourth through groove 62, so that the drain pipe 31 and the fourth through groove 62 are connected through the third connecting pipe 63.

[0074] At the same time, the rotating ring 13 will drive the fourth connecting pipe 64 to rotate synchronously through the fourth connecting rod 610. At this time, one end of the fourth connecting pipe 64 will be flush with the connecting pipe 32, and the other end of the fourth connecting pipe 64 will be flush with the third through groove 61, and the connecting rod and the third through groove 61 will be sealed respectively by two fourth sealing plates 611;

[0075] At this time, water is passed into the first water inlet pipe 21, and the water flows through the second connecting pipe 54 and the first through groove 51 into the upper part of the filter chamber 14, and then the water flows in the reverse direction through the filter element 42 and enters the lower part of the filter chamber 14, so as to backwash the filter element 42, and then the water mixed with the washed stains passes through the fourth through groove 62 and the third connecting pipe 63 and is discharged through the drain pipe 31;

[0076] Before the rotating ring 13 rotates, it is necessary to pull the limit rod 75, so that the locking rod 76 is driven by the push rod 74 to disengage the locking groove 73 on the surface of one of the fixing parts 71, thereby completing the unlocking of the rotating ring 13. After the rotating ring 13 rotates 180 degrees, the limit rod 75 is released. At this time, the locking rod 76 can be driven by the reset spring 77 to engage with the locking groove 73 on the surface of the other fixing part 71, thereby locking the rotating ring 13 after rotation.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
