In this embodiment:

the first step is as follows: in the long-time use of flowing water pump body 1, in order to prevent to accumulate a large amount of impurity in the cartridge filter 15, reduce the filter effect of cartridge filter 15, need regularly clean cartridge filter 15 and filter tube 5, need say that filter tube 5 is dismantled by water inlet 2 this moment, demolish two bolts on with the connecting pipe 29 outer wall through the instrument, can take off connecting pipe 29 together with two end caps by filter tube 5 this moment.

The second step is that: after the completion of the dismantlement of connecting pipe 29, can rotate two handles 8, two handles 8 rotate and drive corresponding dead lever 9 and rotate, thereby drive corresponding connecting rod 10 lateral shifting, two annular fixture blocks 12 drop from corresponding removal post 11 gradually at two connecting rod 10 lateral shifting's in-process, rotate two connecting rods 10 afterwards, take off two annular fixture blocks 12 by corresponding removal post 11, two annular fixture blocks 12 lose the spacing effect to filter tube 5 this moment, can hold filter tube 5 and take off filter tube 5 together with annular stopper 6, can clean the pipe wall of filter tube 5 this moment.

When the filter cartridge 15 needs to be replaced and cleaned, firstly, any one adjusting button is rotated, the rotating rod 25 is driven to rotate by the rotation of the adjusting button, the eccentric wheel 26 is driven to rotate by the rotation of the rotating rod 25, and in the rotating process of the eccentric wheel 26, when the semicircle far away from the circle center turns to the moving rod 27, the moving rod 27 is driven to move transversely, and then the abutting block 28 moves transversely, finally the inclined surface structures of the two corresponding clamping blocks 24 are gradually extruded in the transverse moving process of the abutting cone, so that the two clamping blocks 24 move oppositely, the two driving rods 23 are driven to move oppositely in the opposite moving process of the two clamping blocks 24, so that the two ejector rods 21 move oppositely under the limit of the sliding rod 22, so that the two sliding plates 20 move oppositely, the corresponding first springs are compressed in the opposite moving process of the two sliding plates 20, when the two ejector rods 21 are completely moved out from the corresponding clamping, two ejector pins 21 lose the spacing effect to stock 17, rotate two adjusting knobs in proper order afterwards, time four ejector pins 21 lose the spacing effect to two stock 17, alright at this moment change, clean operation by taking out cartridge filter 15 in two limit groove 13.

After finishing the cleaning operation, needing to mount the filter tube 5, first aligning and putting the two mounting blocks 14 to the corresponding side grooves 13, in the process of putting, the two long rods 17 extend into the corresponding chambers 16, when the two mounting blocks 14 and the filter cartridge 15 are completely put into the corresponding side grooves 13, the two ejector rods 21 are right opposite to the corresponding clamping grooves 18, at this time, the two adjusting buttons are reversely rotated, the two moving rods 27 are reversely moved through the reverse transmission after the two adjusting buttons are reversely rotated, at this time, under the reset effect of the two first springs, the two ejector rods 21 are oppositely moved and enter the corresponding clamping grooves 18, thereby finishing the fixed mounting of the filter cartridge 15, then aligning the annular plug 6 to the annular tube 4 and putting the filter tube 5 into the annular tube 4, at this time, because the annular plug 6 and the annular sealing gasket have resistance to keep sealing in the mounting process, at the moment, the two connecting rods 10 are rotated, the two annular clamping blocks 12 are sleeved on the corresponding movable columns 11, the two handles 8 are rotated in the reverse direction, after the two rod handles 8 are completely pressed to be in a horizontal state through lever transmission of the two fixing rods 9, the two movable columns 11 are pushed by the corresponding annular clamping blocks 12, the annular plugs 6 are completely in precise contact with the annular pipes 4, installation of the filter pipes 5 is completed, and then the two plugs are aligned to the corresponding side grooves 13 and the connecting pipes 29 are installed.

filter the water of suction through setting up cartridge filter 15, prevent that the impurity of aquatic from on attached to some spare parts in flowing water pump body 1 to realize quick dismantlement and the installation to cartridge filter 15 through simple transmission structure, make cartridge filter 15's performance stable always, thereby guarantee flowing water pump body 1's normal use, thereby improve flowing water pump body 1's life.
