[0026] The bottom end of the fixed cylinder 2 is conical; the bottom end of the fixed cylinder 2 is fixedly connected with a discharge port 5, and the valve 6 is installed on the discharge port 5; the impurities can be discharged by opening the valve 6 on the discharge port 5.

[0027] The bottom end of the rotating rod 8 is fixedly connected with a cutter 9, and the cutter 9 is provided with a plurality of cutters and is circumferentially distributed; when the water contains impurities, the cutter 9 located below the filter screen 13 in the fixed cylinder 2 starts to play a role, and with the rotation of the rotating rod 8, the circumferentially distributed cutter 9 cuts the impurities to prevent large-particle impurities from blocking the filter screen 13.

[0028] Structure description: pump body 1: in the center position of the device, it is the core component of the whole circulating pump. Its side wall is accurately connected with the fixed cylinder 2, and the two are connected through the connecting pipe 3 to realize the intercommunication of the internal waterway, build a key path for fluid transmission, finally discharge the water through the top, and the impurity content of the water discharged from the pump body is extremely low, thereby ensuring the efficient and stable operation of the whole circulating pump.

[0029] Fixed cylinder 2: similar to a purification workshop, one side is connected to the water pipe 4 to introduce the water to be treated, and the inside is orderly arranged with filter screen 13, filter assembly and cleaning assembly. The conical design at the bottom is unique, and the discharge port 5 and valve 6 are located at the bottom end, which can effectively control the discharge process of impurities and ensure the smooth progress of the whole filtration and purification process.

[0030] Connecting pipe 3: as the water conveying link between pump body 1 and fixed cylinder 2, it precisely builds the key passage of internal water flow circulation, so that the "clean" water filtered by filter screen 13 can smoothly flow from fixed cylinder 2 to pump body 1, ensuring stable and efficient water flow transmission.

[0031] Water pipe 4: responsible for introducing the water to be treated into the fixed cylinder 2, providing water source for the whole circulating pump, and is the starting part of the pumping process. Its connection with the fixed cylinder 2 must be sealed to prevent water leakage and other problems from affecting the normal operation of the circulating pump.

[0032] Discharge port 5: located at the end of the conical area at the bottom end of the fixed cylinder 2, it works with valve 6. When it is necessary to discharge the impurities accumulated at the bottom of the fixed cylinder 2, open the valve 6, and the impurities will be smoothly discharged through the discharge port 5. Its design position and structure are conducive to quickly and thoroughly cleaning impurities.

[0033] Valve 6: installed on the discharge port 5, it plays a key role in controlling the discharge of impurities. By opening or closing the valve 6, the timing and flow of impurity discharge can be precisely controlled to ensure the orderly progress of the impurity cleaning process, while keeping it closed during normal water pumping and filtering to prevent water leakage.

[0034] Motor 7: as the power source of the whole device, it provides strong power for the operation of the rotating rod 8 and related components. When the filter screen 13 needs to be cleaned, the motor 7 is started, and the power is instantly transmitted to the rotating rod 8, which drives the cleaning assembly to work, realizing the automatic vibration cleaning of the filter screen 13 and restoring its filtering activity.

[0035] Rotating rod 8: as an important component of power transmission, after the motor 7 is started, it receives and transmits power to the fixed box 14, driving it to rotate at high speed, which in turn causes the knocking block 16 to knock the semicircular convex block 11, causing the filter screen 13 to vibrate and clean impurities. At the same time, the rotating rod 8 closely cooperates with the cutter 9 to cut off large particles in water when they are encountered, optimizing the filtering process.

[0036] Cutter 9: circumferentially distributed on the rotating rod 8 below the filter screen 13 in the fixed cylinder 2, when large particles are hidden in the water, the cutter 9 will rotate at high speed with the rotating rod 8, cutting off the particles like a sharp blade, effectively resolving the crisis of clogging the filter screen 13, ensuring the continuous and efficient operation of the filtering process.

[0037] Support ring 10: As a stable support component of filter screen 13, it is firmly rooted in the inner wall of fixed cylinder 2, providing a solid foundation for filter screen 13 to resist water flow impact. In cooperation with rubber ring 12, it greatly reduces the risk of impurities entering pump body 1, ensuring the long-term stable operation of pump body 1.

[0038] Half-round protrusions 11: Distributed circumferentially on the top of filter screen 13, they cooperate with knocking block 16. When motor 7 drives rotating rod 8 to rotate fixed box 14, knocking block 16 continuously knocks half-round protrusions 11 under the action of centrifugal force, causing filter screen 13 to vibrate violently, thereby shaking off impurities accumulated at the bottom, achieving automatic cleaning of filter screen 13.

[0039] Rubber ring 12: It tightly fits the inner wall of fixed cylinder 2 and the outer wall of filter screen 13, playing a sealing and leakage repair role. In cooperation with support ring 10, it prevents unfiltered water from mixing into the pure area, ensuring the purity of water entering pump body 1 and providing protection for the stable operation of pump body 1.

[0040] Filter screen 13: It is the key filtering component inside fixed cylinder 2, with its fine pores, it quickly starts at the beginning of water pumping, intercepting miscellaneous particulate impurities in the water, providing preliminary purification for the water entering pump body 1. At the same time, filter screen 13, together with support ring 10 and rubber ring 12, forms a solid filtering "iron triangle", and through cooperation with the cleaning assembly, it realizes automatic cleaning and long-term filtering function.

[0041] Fixed box 14: Its side wall is tightly fixed with rotating rod 8. After motor 7 is started, it rotates rapidly with rotating rod 8, using centrifugal force to drive knocking block 16 restrained by spring 15 inside to move, thereby knocking half-round protrusions 11 and causing filter screen 13 to vibrate and clean impurities.

[0042] Spring 15: Located inside fixed box 14, one end is connected with knocking block 16. Under the action of centrifugal force generated by the rotation of fixed box 14, spring 15 is stretched or compressed, restraining knocking block 16 to make reciprocating motion, so that knocking block 16 can continuously and forcefully knock half-round protrusions 11, ensuring the cleaning effect of filter screen 13.

[0043] Knocking block 16: Under the restraint of spring 15, it is located inside fixed box 14. When fixed box 14 rotates with rotating rod 8, knocking block 16 continuously knocks half-round protrusions 11 distributed circumferentially on the top of filter screen 13 under the action of centrifugal force, causing filter screen 13 to vibrate violently and causing impurities at the bottom to fall off, achieving automatic vibration cleaning of filter screen 13.
