[0027] like Figures 1 to 4 , Figure 7 As shown, the present invention discloses a water pump structure with good pet filtration effect, including a pump housing 1. The pump housing 1 has a water inlet channel 10. To achieve the purpose of the invention, an outer mesh body 101 and an inner mesh body 102 are arranged sequentially in the water inlet channel 10 along the water flow direction. An embedding cavity 20 for embedding a filter module is reserved between the outer mesh body 101 and the inner mesh body 102. The pump housing 1 has a through embedding channel 30, which penetrates the embedding cavity 20.

[0028] In the structure of this water supply pump, not only are an outer mesh body 101 and an inner mesh body 102 sequentially arranged along the water flow direction in the inlet channel 10, but an embedding cavity 20 for embedding the filter module is also reserved between the outer mesh body 101 and the inner mesh body 102, and an embedding channel 30 is opened on the pump casing 1, penetrating the pump casing 1 and the embedding cavity 20. This can help to limit the filter module in multiple directions, thereby ensuring that the installation and positioning of the filter module is very stable and reliable, thus achieving a very stable and reliable filtration effect; moreover, it can also facilitate the installation and removal of the filter module, allowing users to quickly install and remove the filter module themselves, thereby effectively improving the convenience of water pump maintenance.

[0029] In this water supply pump structure, not only can the outer mesh body 101 and the inner mesh body 102 restrict the filter module, but the two opposing cavity walls of the mounting cavity 20 can also restrict it. This can help to limit the filter module in multiple directions, thereby ensuring that the installation and positioning of the filter module is very stable and reliable, and thus helping to achieve a very stable and reliable filtration effect.

[0030] Since the mounting channel 30 passes through the pump housing 1 and the mounting cavity 20, it not only facilitates the accurate placement of the filter module in the mounting cavity 20, but also allows the user to quickly detach the filter module from the pump housing 1 by pushing the filter module in the opposite direction of the filter module mounting direction. This makes it extremely convenient for the user to disassemble the filter module, and the user can quickly disassemble and assemble the filter module by themselves, thereby effectively improving the convenience of water pump maintenance.

[0031] like Figure 2 and Figure 7 As shown, a positioning protrusion 40 is provided in the mounting cavity 20 or mounting channel 30. The positioning protrusion 40 can block and restrict the filter module, so as to accurately position the filter module during installation, thereby facilitating faster, more accurate and stable installation of the filter module, and further improving the reliability and applicability of the water supply pump structure.

[0032] like Figure 2 and Figure 7 As shown, the positioning protrusion 40 is disposed on the channel opening of the embedding channel 30. This ensures that the positioning protrusion 40 has a very good positioning function while avoiding it from encroaching on the filtration space of the filter module. This not only facilitates a wider filtration range but also allows for the manufacture of a compact and small-sized water pump, which improves the applicability of the water supply pump structure.

[0033] like Figures 1 to 4 , Figure 7 As shown, the water inlet channel 10 is located on the front wall of the pump casing 1, and the mounting channel 30 extends laterally through the pump casing 1 and the mounting cavity 20. This not only achieves excellent water inlet performance but also limits the movement of the filter module in front, behind, up, and down, and allows the filter module to be quickly detached from the pump casing 1 by pushing it laterally, thereby further improving the applicability of the water supply pump structure.

[0034] The filter module is an existing block-shaped filter module (not shown in the figure), which can meet the requirements of stable embedding and filtration.

[0035] like Figures 1 to 4As shown, a locking notch 50 is provided on the pump housing 1. This locking notch 50 enables the water pump structure to be stably positioned in the water tank of the pet water fountain, thereby facilitating a more stable and reliable water supply effect and further improving the reliability and applicability of the water pump structure.

[0036] like Figures 1 to 4 As shown, the mounting notch 50 is located on the bottom edge of the pump casing 1. This helps to stably confine the water supply pump structure to the bottom of the water storage chamber of the water tank, thereby achieving a more stable and comprehensive water supply effect, and further improving the reliability and applicability of the water supply pump structure.

[0037] In the actual manufacturing process, a protruding part matching the locking notch 50 is provided at the bottom of the water storage chamber of the pet water fountain's water tank, and the locking notch 50 is tightly locked onto the protruding part. This stably limits the water supply pump structure to the bottom of the water storage chamber, thereby facilitating a more stable and comprehensive water supply effect.

[0038] like Figures 1 to 5 As shown, the pump casing 1 includes a front casing 11 and a rear casing 12. The water inlet channel 10 extends longitudinally through the front casing 11. The outer mesh body 101 and the inner mesh body 102 are arranged side by side in the water inlet channel 10 on the front casing 11. The mounting channel 30 extends transversely through the front casing 11. A pumping chamber 60 for mounting a pump impeller is formed on the front wall of the rear casing 12. The rear end of the front casing 11 is connected to the front end of the rear casing 12, and the water inlet channel 10 is connected to the pumping chamber 60. This pump casing 1 is very simple and reliable, which not only facilitates manufacturing but also helps to achieve a very reliable water supply effect, thereby helping to further improve the reliability and applicability of the water supply pump structure.

[0039] like Figures 3 to 6 , Figures 8 to 11As shown, the front and rear walls of the rear housing 12 are respectively provided with a front mounting groove 121 and a rear mounting groove 122. The bottom of the front mounting groove 121 is provided with a protruding ring 123, and an impeller cover 13 is embedded in the protruding ring 123. The pump water chamber 60 is formed between the impeller cover 13 and the bottom of the front mounting groove 121. The bottom of the rear mounting groove 122 is provided with a positioning cylinder 124. The inner hole of the positioning cylinder 124 forms a mounting hole 125 for rotor installation, and the front end of the mounting hole 125 extends into the pump water chamber 60. The rear end of the positioning cylinder 124 is provided with a positioning tube 126 for rotor positioning shaft to be embedded. The front mounting slot 121 is used for guiding water, and the rear mounting slot 122 is used for the circuit part and stator of the water pump. This not only facilitates the manufacturing of the pump chamber 60, but also facilitates better matching between the stator and rotor, and helps to ensure better overall sealing, thereby helping to further improve the reliability and applicability of the water pump structure.

[0040] like Figure 9 and Figure 10 As shown, several reinforcing ribs 127 are provided between the outer wall of the positioning tube 126 and the rear wall of the positioning cylinder 124. This enables the positioning tube 126 to perform a more stable and reliable positioning function, thereby helping to further improve the reliability and applicability of the water supply pump structure.

[0041] like Figures 4 to 6 As shown, the positioning tube 126 is used to fix and embed the rear end of the rotor positioning shaft (not shown in the figure), and the rotor positioning shaft forms a seal on the inner hole of the positioning tube 126, so that the front mounting groove 121 and the rear mounting groove 122 are not connected. The rotor (not shown in the figure) is rotatably mounted on the rotor positioning shaft. The stator 14 is fitted on the positioning cylinder 124, and the stator 14 corresponds to the rotor. The control circuit module (not shown in the figure) and the stator 14 of this water supply pump structure are installed in the rear mounting groove 122. The pump impeller (not shown in the figure) is connected to the front end of the rotor and is located in the pump chamber 60. The groove opening of the rear mounting groove 122 is sealed with a sealing cap (not shown in the figure). This can well meet the actual manufacturing and use requirements and facilitate the long-term stable water supply effect.

[0042] like Figure 10 As shown, the top of the rear shell 12 is provided with a protruding tube portion 128, the inner hole of which is a water outlet 1281, and the water outlet 1281 is connected to the output end of the pump water chamber 60. This facilitates connection to the water supply pipe, thereby enabling a better water supply effect.

[0043] like Figure 1 , Figure 3 and Figure 4As shown, the rear end of the front housing 11 is fitted onto the front end of the rear housing 12. The rear wall of the front housing 11 has an anti-misalignment notch 111, and the rear housing 12 has an anti-misalignment protrusion 129 that matches the anti-misalignment notch 111. The cooperation between the anti-misalignment notch 111 and the anti-misalignment protrusion 129 not only enhances the accuracy of assembly but also improves assembly stability, thereby helping to further improve the reliability and applicability of the water pump structure.
