[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figures 1 to 6 As shown, the present invention can be implemented through the following embodiments: A novel water filter pump includes a pump body 11 and an inlet pipe 22. An installation port 2121 is provided at the inlet pipe 22. A filter assembly 33 is installed in the installation port 2121. The filter assembly 33 includes a connecting plate 3131, a filter screen 3232, and a receiving plate 3333. A dirt removal part 2222 is provided below the inlet pipe 22. Connecting parts 211211 are provided on both sides of the installation port 2121. Connecting grooves 212212 are provided in the connecting parts 211211. Connecting blocks 311311 corresponding to the connecting grooves 212212 are provided on both sides of the connecting plate 3131. A lifting plate 312312 is provided on the top of the connecting plate 3131.

[0023] The filter assembly 33 is installed inside the mounting port 2121. After the filter assembly 33 is engaged with the mounting port 2121 outside the water inlet pipe 22, the filter assembly 33 can be disassembled, improving the efficiency of replacing the filter screen 3232. The receiving plate 3333 is used to receive impurities filtered by the filter screen 3232. During the replacement of the filter screen 3232, most of the impurities can be carried out. During the disassembly and assembly of the filter screen 3232, the impurities are carried out and cleaned. The cleaning part 2222 is used to flush clean water into the water inlet pipe 22 after the filter assembly 33 is removed, so that residual impurities can be removed from the cleaning part 2222. The connecting part 211211 is inserted into the connecting groove 212212 and is fixedly connected by the limiting component. The lifting plate 312312 is used by the maintenance personnel to lift and remove the filter assembly 33.

[0024] like Figure 2 and Figure 4 As shown, an outlet 2323 is provided between the cleaning section 2222 and the inlet pipe 22, and a transition slope 231231 is provided between the outlet 2323 and the inlet pipe 22. The outlet 2323 is used for sewage carrying impurities to pass through, so that the sewage flows into the cleaning section 2222 and is discharged from the inlet pipe 22; the transition slope 231231 is used to transition the outlet 2323 and the inlet pipe 22, improve the connection strength 211211, and facilitate the flow of sewage into the cleaning section 2222 by gravity.

[0025] like Figure 3 , Figure 5 and Figure 6As shown, the connecting block 311311 has a slot 311a311a, the connecting part 211211 is equipped with a locking rod 44, the locking rod 44 is provided with a push plate 4141, and a spring 55 is provided between the push plate 4141 and the connecting part 211211. The locking rod 44 is a limiting element installed on the connecting part 211211. After the locking rod 44 is engaged with the slot 311a311a, the filter assembly 33 is engaged with the water inlet pipe 22, which facilitates the installation and replacement of the filter assembly 33. The spring 55 abuts against the push plate 4141 and is installed between the connecting part 211211 and the push plate 4141, so that after the locking rod 44 is disengaged from the slot 311a311a, the locking rod 44 quickly resets, improving disassembly efficiency and preparing for the next assembly.

[0026] like Figure 3 , Figure 5 and Figure 6 As shown, a pad 5151 is installed on the spring 55, and the end of the locking rod 44 is provided with a thread 4242. A thread 311b 311b is provided in the slot 311a 311a. The thread 4242 and the thread 311b 311b engage to fix the locking rod 44 in the slot 311a 311a, preventing the locking rod 44 from accidentally springing back and improving the stability of the connection between the filter assembly 33 and the water inlet pipe 22. The pad 5151 is used to hold the push plate 4141 against it, so that the push plate 4141 will not wear against the spring 55 when the locking rod 44 rotates, thus improving the life of the spring 55.

[0027] like Figure 2 and Figure 5 As shown, a sealing part 331331 is provided at the bottom of the receiving plate 3333. The sealing part 331331 has a groove 332332, and a sealing strip 66 is installed in the groove 332332. The sealing part 331331 is used to seal the water outlet 2323 to prevent water from flowing into the pump body 11 through the dirt removal part 2222, which would damage the pump body 11. The groove 332332 and the sealing strip 66 cooperate to increase the contact surface between the sealing part 331331 and the water outlet 2323, thereby improving the sealing performance.

[0028] like Figure 1 and Figure 2 As shown, the cleaning section 2222 is equipped with a cover plate 77, which is fixed to the cleaning section 2222 by screws 7171. The cover plate 77 is installed inside the cleaning section 2222 to prevent water from leaking out of the cleaning section 2222.

[0029] like Figure 1As shown, the water inlet pipe 22 has a mounting part 2424 on the right side of the mounting port 2121. A mounting groove 2525 is formed on the mounting part 2424, and a sealing plate 88 is installed inside the mounting groove 2525. The sealing plate 88 is fixedly connected to the mounting groove 2525 by screws 8181. The sealing plate 88 inside the mounting part 2424 prevents water from flowing out of the mounting part 2424. Screws 8181 are used to connect the sealing plate 88 and the mounting groove 2525 to prevent the sealing plate 88 from detaching from the mounting groove 2525, thus preventing water in the water inlet pipe 22 from contacting the outside.

[0030] like Figures 2 to 4 As shown, an annular groove 251251 is formed at the mounting groove 2525, and a baffle 99 is installed inside the annular groove 251251. When removing residual impurities, the baffle 99 is snapped onto the sealing plate 88, and a rubber sealing sleeve is provided outside the baffle 99. Through the cooperation between the baffle 99 and the annular groove 251251, sewage is prevented from entering the pump body 11, and the sewage is driven to flow out from the cleaning section 2222.
