The water wheel 96 comprises a centrifugal water wheel 962, a circular-tube-shaped water wheel sleeve 961 coaxially connected to the lower end of the centrifugal water wheel through a ratchet mechanism, and more than one group of axial flow blades 966 formed on the periphery of the water wheel sleeve and positioned below the centrifugal water wheel; a connecting ring 963 is integrally connected between the peripheries of the lower ends of the centrifugal water wheels, and more than one permanent magnet 965 is mounted at the lower end of the connecting ring; the axial flow blades are positioned in the range of the water inlet pipe part.

The water wheel sleeve is sleeved on the driving shaft in a sliding manner; the lower end of the water wheel sleeve is formed with a step-shaped spring sleeving part 967, the threaded part of the driving shaft is connected with a nut 96b, and a spring 96a is arranged between the spring sleeving part and the nut outside the driving shaft.

When the ratchet mechanism enables the driving shaft to rotate clockwise, the water wheel sleeve drives the axial flow blade and the centrifugal water wheel to rotate simultaneously; when the drive shaft anticlockwise rotates, the water wheel sleeve pipe drives the axial flow blades to rotate, and the centrifugal water wheel does not rotate.

The height of the centrifugal water wheel is smaller than that in the pump shell, and a Hall sensor 922 is arranged at the lower end of the pump shell corresponding to the position of the permanent magnet; when the water wheel compresses the spring and moves downwards to the limit position, the permanent magnet is close to the Hall sensor, so that the Hall sensor detects signals.

The lower end of the water inlet pipe part is fixedly connected with a filtering seat 931, the lower end of the filtering seat is connected with a water inlet joint 932, and a filtering plate 97 is arranged between the filtering seat and the water inlet joint; the inner wall of the filter seat is provided with a mounting step portion 9312 for positioning the filter plate, and the upper end of the water inlet joint is provided with a filter plate positioning portion 9321 which is matched with the mounting step portion to clamp the filter plate; and a round hole for the round rod part of the driving shaft to pass through is formed in the middle of the filter plate.

The filter plate is a ceramic filter plate or a stainless steel perforated plate processed by laser drilling.

The side wall of the filter seat is integrally connected with a drainage joint 9311 at the position below the filter plate, and the side wall of the positioning part of the filter plate is provided with a water through hole corresponding to the drainage joint; the drain connector is connected to an electromagnetic valve 95.

The water inlet joint and the transition position of the filter plate positioning part form a step part, the upper end part of the inner periphery of the water inlet joint is connected with a rotating connecting frame 98, and the rotating connecting part of the driving shaft is rotatably connected with the middle of the rotating connecting frame.

The rotating connecting portion is provided with a rubber one-way valve block 933 in a sealing sleeve mode, and the periphery of the one-way valve block abuts against a step portion of the water inlet joint. When rivers flowed into water supply connector from bottom to top, the check valve piece was upwards promoted and is in the conducting state by rivers, and when rivers flowed to the filter below from the filter top see through the filter board, the check valve piece periphery was supported on the step portion and is in the encapsulated situation.

The rotating connecting part is rotatably sleeved with a scraping frame 98 used for scraping dirt attached to the lower end face of the filter plate; the scraping frame comprises an inner connecting ring 981 sleeved outside the rotating connecting part. The outer clamping ring 985 with the coaxial setting of in-connection circle to and the splice bar 982 of an organic whole connection more than two between outer clamping ring and in-connection circle, the elastic doctor-bar 983 of upper end fixed connection of every splice bar, install between in-connection circle lower extreme and the check valve piece and be used for scraping the thrust spring 98a that the frame pushed up, the inner wall shaping of in-connection circle have with drive screw thread portion threaded connection's interior arch (not shown).

The axial flow blade is low on the left and high on the right, and the driving thread part is a left-hand thread.

The motor, the Hall sensor and the electromagnetic valve are respectively and electrically connected with the controller; in a normal working state, the controller drives the motor to rotate clockwise, and the axial flow blades generate upward thrust on water in the water inlet pipe part; at this time, the lower end of the driving screw thread part is in a state of abutting against but not meshing with the inner protrusion of the scraping frame, and the scraping blade is far away from the filter plate. Thus the scraper frame is in the non-working state.

When the filter plate is blocked, the pressure difference between the upper side and the lower side of the axial flow blade is increased, when the pressure difference is larger than the elastic force of the spring, the water wheel overall compression spring moves downwards, so that the permanent magnet moves downwards to be close to the Hall sensor, after the Hall sensor detects a signal, the controller controls the motor to rotate anticlockwise, so that the inner protrusion of the scraping frame is meshed with the driving threaded part under the pushing of the thrust spring, the scraping blade is abutted to the filter plate, and after the scraping frame is blocked by the filter plate and cannot continue to move upwards, the scraping frame rotates along with the driving shaft to scrape off dirt on the filter plate.

When a motor of the filter pump rotates clockwise, the centrifugal water wheel and the axial flow blade are both in a working state, the axial flow blade pumps water flow upwards, then the water is thrown outwards through the centrifugal water wheel and finally discharged from the water outlet joint, and the axial flow blade plays an auxiliary role in pumping water of the centrifugal water wheel in the state; when the motor anticlockwise rotates, the axial flow blades drive water to wash the filter plate up and down in a countercurrent mode, and the water with dirt is discharged through the electromagnetic valve, so that the filter pump can pump filtered clean water, self-cleaning can be achieved, and the maintenance-free service time is prolonged. In addition, when the filter plate is blocked, the (switch type) Hall sensor is matched with the axial flow blade to drive the water wheel to integrally move so as to judge whether the filter plate is blocked, and compared with the method of detecting the pressure in the water inlet pipe by using a fluid pressure sensor, the method and the device are simpler in control. In addition, the scraping frame only works in the back flushing state of the filter plate and does not work in the normal working state of the filter pump, so that the energy consumption of the motor cannot be obviously increased.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
