[0026] In the description of the present invention, the description referring to terms such as "one embodiment", "some alternative embodiments" or "some alternative examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention.

[0027] Please refer to Figure 1 and Figure 2 , an embodiment of the present invention provides an anti-flushing full-process water treatment device, including: a main body 10, a filter screen assembly 20, a cleaning execution device 30, and an electromagnetic generating device 40.

[0028] A treatment chamber 11 is provided inside the main body 10. An inlet 12, an outlet 13 and a sewage outlet 14 are provided inside the treatment chamber 11. The filter screen assembly 20 is arranged inside the treatment chamber 11 and forms a filtering chamber 21 around it. The filtering chamber 21 is respectively communicated with the inlet 12 and the sewage outlet 14. The sewage outlet 14 is located outside the filtering chamber 21. A sewage control valve 15 is arranged on the sewage outlet 14. The sewage control valve 15 is used to open or close the sewage outlet 14. The cleaning execution device 30 includes a baffle 31 and a power assembly 32. The baffle 31 is movably arranged inside the filtering chamber 21 and is located between the inlet 12 and the sewage outlet 14. The power assembly 32 is drivingly connected with the baffle 31. The baffle 31 opens or disconnects the communication between the inlet 12 and the sewage outlet 14 through the filtering chamber 21 under the drive of the power assembly 32. When the baffle 31 disconnects the communication between the inlet 12 and the sewage outlet 14 through the filtering chamber 21, the baffle 31 divides the filtering chamber 21 into a front chamber and a rear chamber. The front chamber is communicated with the inlet 12, and the rear chamber is communicated with the sewage outlet 14. The electromagnetic generating device 40 is connected with an electromagnetic energy release device 41. The electromagnetic energy release device 41 is arranged inside the treatment chamber 11.

[0029] Please refer to Figure 3 , in the normal water treatment mode, the baffle 31 opens the filtering chamber 21, so that the inlet 12 can be communicated with the sewage outlet 14 through the filtering chamber 21. The sewage control valve 15 closes the sewage outlet 14. Water enters the treatment chamber 11 from the inlet 12, and then sequentially passes through the filtering chamber 21 and the outlet 13. The electromagnetic generating device 40 generates high-frequency electromagnetic wave signals, and emits electromagnetic waves to the surrounding water body through the electromagnetic energy release device 41, exciting water molecules to generate resonance, enhancing the internal energy of water, forming non-adhesive vaterite / aragonite calcium carbonate in the cooling water and forming a magnetic ring layer on the steel surface, thereby solving the problems of scaling and corrosion. At the same time, the ion current pulse wave generated by the electromagnetic generating device 40 can also achieve a significant effect of killing microorganisms and control the growth of bacteria and algae. The impurities generated by the action of the electromagnetic waves will adhere to the filter screen assembly 20 when the water flow passes from the filtering chamber 21 to the outlet 13, thereby realizing filtration.

[0030] Please refer to Figure 4, in the backwashing mode, the baffle plate 31 disconnects the filtration chamber 21 and divides the filtration chamber 21 into a front chamber and a rear chamber. The front chamber is communicated with the water inlet 12, and the rear chamber is communicated with the sewage outlet 14, so that the water inlet 12 cannot communicate with the sewage outlet 14 through the filtration chamber 21, and the water at the water inlet 12 cannot directly flow to the sewage outlet 14 through the filtration chamber 21. The sewage control valve 15 opens the sewage outlet 14. In the filtration chamber 21, the water in the front chamber flows out of the filtration chamber 21 due to the blockage of the baffle plate 31. Under the action of water pressure, the water will then rush into the rear chamber, realizing the backwashing function, flushing the impurities on the filter net assembly 20 located in the rear chamber. Subsequently, the impurities are discharged from the sewage outlet 14 under the drive of the water flow. In the backwashing mode, the water outlet 13 can be selected to be closed or opened. Closing the water outlet 13 is beneficial to improving the flushing effect.

[0031] In some alternative embodiments, the electromagnetic energy release device 41 is disposed between the water inlet 12 and the filtration chamber 21, so that the water contacts the electromagnetic energy release device 41 before entering the filtration chamber 21, improving the water treatment effect.

[0032] In some alternative embodiments, the water inlet 12 is disposed at the top of the treatment chamber 11, the water outlet 13 is disposed at the side of the treatment chamber 11, and the sewage outlet 14 is disposed at the bottom of the treatment chamber 11. The filter net assembly 20 extends in the direction from top to bottom, so that the impurities can settle at the sewage outlet 14 by gravity, facilitating sewage discharge.

[0033] To facilitate centralized flushing of impurities, in some alternative embodiments, the horizontal height of the baffle plate 31 is higher than the horizontal height of the water outlet 13. Since the impurities are mainly located in the lower half of the filtration chamber 21 due to gravity and mainly gather at the position of the filter net assembly 20 close to the water outlet 13 due to the flow of water, and the horizontal height of the baffle plate 31 is higher than the horizontal height of the water outlet 13, the impurities in the filtration chamber 21 are mainly located in the rear chamber. In the backwashing mode, the impurities in the rear chamber fall off from the filter net assembly 20 under the flushing of water and then are discharged from the sewage outlet 14.

[0034] In some alternative embodiments, the filter screen assembly 20 includes a filter cartridge 22 and an annular flow guide plate 23. The filter cartridge 22 is disposed within the processing chamber 11. A filter chamber 21 is formed within the filter cartridge 22. The top opening of the filter cartridge 22 communicates with the water inlet 12, and the bottom opening of the filter cartridge 22 communicates with the sewage outlet 14. The annular flow guide plate 23 is connected between the edge of the top opening of the filter cartridge 22 and the inner wall of the processing chamber 11. The annular flow guide plate 23 blocks the communication between the water inlet 12 and the gap between the filter cartridge 22 and the inner wall of the processing chamber 11, such that the water entering from the water inlet 12 directly enters the filter chamber 21 and then discharges from the filter chamber 21, so that impurities are intercepted by the filter cartridge 22 and do not directly enter the gap between the filter cartridge 22 and the inner wall of the processing chamber 11, avoiding impurities directly entering the water outlet 13. The inner diameter of the annular flow guide plate 23 gradually increases in the direction from the top opening of the filter cartridge 22 to the water inlet 12, thereby guiding the water into the front chamber of the filter chamber 21.

[0035] In some alternative embodiments, the filter screen assembly 20 includes a filter cartridge 22 and an annular current collecting plate 24. The filter cartridge 22 is disposed within the processing chamber 11. A filter chamber 21 is formed within the filter cartridge 22. The top opening of the filter cartridge 22 communicates with the water inlet 12, and the bottom opening of the filter cartridge 22 communicates with the sewage outlet 14. The annular current collecting plate 24 is connected between the edge of the bottom opening of the filter cartridge 22 and the sewage outlet 14. The annular current collecting plate 24 blocks the communication between the sewage outlet 14 and the gap between the filter cartridge 22 and the inner wall of the processing chamber 11. In the backwashing mode, the water in the gap between the filter cartridge 22 and the inner wall of the processing chamber 11 will be blocked by the annular current collecting plate 24 and cannot directly enter the sewage outlet 14, thereby causing the water to backflush into the filter chamber 21. The inner diameter of the annular current collecting plate 24 gradually decreases in the direction from the bottom opening of the filter cartridge 22 to the sewage outlet 14, thereby guiding the impurities to enter the sewage outlet 14 from the rear chamber of the filter chamber 21.

[0036] The specific structure of the power assembly 32 can be designed according to actual needs. For example, in some alternative embodiments, the power assembly 32 includes a motor 33 and a drive shaft 34. The motor 33 is disposed outside the main body 10 and is drivingly connected to the drive shaft 34. The drive shaft 34 extends into the processing chamber 11 and is drivingly connected to the blocking plate 31. The motor 33 drives the blocking plate 31 to rotate, thereby realizing opening or disconnecting the communication between the water inlet 12 through the filter chamber 21 and the sewage outlet 14.

[0037] In some alternative embodiments, a controller 50 is disposed outside the main body 10. The controller 50 is respectively in signal connection with the electromagnetic generating device 40, the power assembly 32, and the sewage control valve 15. The user can control the electromagnetic generating device 40, the power assembly 32, and the sewage control valve 15 through the controller 50, which is convenient for operation.

[0038] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
