[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0013] Please see Figures 1 to 5 This invention provides a technical solution: a filter-type circulating water pump, comprising a circulating pump body 1 and a filter head. The technical principle of the circulating pump body 1 for circulating water is disclosed and will not be described in detail in this application. The filter head functions to divert and filter the water flow. One end of the circulating pump body 1 is provided with an integral inlet pipe 11, through which water flows. The combined filter head includes a filter housing 2, a sealing ring 3, and an inlet housing 4. Water flows into the inlet housing 4, and after being diverted by the sealing ring 3, it enters the filter housing 2. The water flows within the filter housing 2, and the flowing water is filtered by the filter baffle 313 to remove impurities before being conveyed into the inlet pipe 11, thus completing the diversion and filtration of the water flow. The sealing ring 3 is installed between the filter housing 2 and the inlet housing 4. The filter housing 2 is installed on the inlet pipe 11. A snake-shaped flow channel plate 22 is fixedly connected inside the filter housing 2, so that the water flow is snake-shaped and increases the length of the water flow channel, which is beneficial for filtering the water entering the inlet pipe 11. The flow channel plate 22 and the interior of the filter housing 2 form a water delivery channel 23. The water flow is snake-shaped in the water delivery channel 23. The sealing ring 3 is provided with an integrated sealing tube 31. The sealing tube 31 has water permeable holes 312. The sealing tube 31 serves to divide the water flow. The water flows through the separated water permeable holes 312. The surface of the sealing tube 31 facing the filter housing 2 is provided with an integrated water filter bending plate 313. The water filter bending plate 313 has filter holes to filter impurities in the water flow.

[0014] In this embodiment, a positioning ring groove 24 is provided on the surface of the filter fixing shell 2 facing the sealing tube 31. The sealing tube 31 is fitted with the positioning ring groove 24 with a clearance. One end of the sealing tube 31 is embedded in the positioning ring groove 24 and the water inlet shell 4, so that the filter fixing shell 2, the sealing ring 3 and the sealing tube 31 are installed accurately. The centers of the filter fixing shell 2, the sealing ring 3 and the sealing tube 31 are on the same axis. The outer diameters of the filter fixing shell 2, the sealing ring 3 and the water inlet shell 4 are the same.

[0015] In this embodiment, the filter bending plate 313 is distributed in the water conveying channel 23. The end surface of the filter bending plate 313 matches the surface of the channel plate 22. The filter bending plate 313 is installed accurately. The filter bending plate 313 is provided with filter holes. The filter bending plate 313 plays the role of filtering impurities in the water flow.

[0016] In this embodiment, a water inlet groove 311 is provided at one end of the sealing tube 31. The cross-section of the water inlet groove 311 is a right trapezoidal shape. The water permeable hole 312 is connected to the water inlet groove 311. Water flows from the water inlet housing 4 into the water inlet groove 311, and then from the water inlet groove 311 through the water permeable hole 312 into the water conveying channel 23 inside the filter fixing housing 2. The water flow in the water conveying channel 23 flows in a serpentine shape and is filtered by the filter bending plate 313.

[0017] In this embodiment, the filter fixing shell 2 is provided with an integrated water outlet 25, which is connected to the filter fixing shell 2. The water outlet 25 is embedded inside the water inlet pipe 11, so that the water in the water delivery channel 23 enters the circulating pump body 1.

[0018] In summary, the sealing pipe 31 has water permeable holes 312, which serve to divert water flow. Water flows through the separate water permeable holes 312 and enters the water supply channel 23 inside the filter housing 2. The water flows in a serpentine shape within the water supply channel 23 and is filtered by the filter baffle 313. This design effectively diverts the water flow and filters impurities in the water. Example

[0019] Please see Figures 1 to 6 This embodiment is the second embodiment of the present invention. In this embodiment, the effect of a robust filter fixing shell 2 is added. A robust component is provided between the water inlet pipe 11 and the filter fixing shell 2. The robust component includes a robust ring 111 and a positioning component. The robust ring 111 is connected to the water inlet pipe 11 by a threaded connection. The position of the robust ring 111 can be adjusted. The positioning component includes a stabilizing block 112, a fixing plate 21, and a positioning post 211. The stabilizing block 112 is installed on the outside of the water inlet pipe 11. The fixing plate 21 is installed on the side of the filter fixing shell 2. The water outlet 25 extends into the interior of the water inlet pipe 11. Then, the positioning post 211, which passes through the fixing plate 21, extends into the interior of the stabilizing block 112. The fixing plate 21 and the filter fixing shell 2 are an integral structure. By rotating the robust ring 111, the robust ring 111 and the bent fixing plate 21 are connected by a threaded connection, which serves to secure the filter fixing shell 2.

[0020] In this embodiment, the fixing plate 21 is curved, and the center of the fixing plate 21 is on the same axis as the center of the water inlet pipe 11. The stabilizing block 112 is provided with a circular groove for the positioning post 211 to be inserted. The end of the positioning post 211 is inserted into the stabilizing block 112, which serves to limit the fixing plate 21. The fixing plate 21 is provided with a circular hole for the positioning post 211. The end of the positioning post 211 is provided with a fixing magnet 2111. The fixing magnet 2111 is attracted and connected to the fixing ring 111. The fixing ring 111 is connected to the curved fixing plate 21 by threaded engagement, which serves to firmly fix the filter fixing shell 2.

[0021] In summary, the end of the positioning post 211 is embedded in the stabilizing block 112, which limits the fixing plate 21 and prevents it from loosening. The fixing ring 111 is connected to the bent fixing plate 21 by threaded engagement, which plays the role of firmly filtering and fixing the shell 2.
