[0023] The following further describes the present application in detail with reference to the accompanying drawings.

[0024] As Figures 1 to 5 shown, the present application provides a submersible pump, including a top cover 1, a pump body 2, a base 3 and an outlet pipe 4. The top cover 1, the pump body 2 and the base 3 are detachably connected in sequence. The outlet pipe 4 is connected to the pump body 2 and is communicated with the inside of the pump body 2.

[0025] The top cover 1 is detachably connected to the pump body 2 by screws, and a handle 5 is provided at the top. The handle 5 can be an arc-shaped structure, a rectangular structure or a trapezoidal structure. Specifically, the handle 5 is a semi-circular structure. A first groove 51 and two second grooves 52 are formed along the length direction of the handle 5 at the top of the handle 5. The first groove 51 is a long groove with a semi-circular structure. The two second grooves 52 are arranged on both sides of the first groove 51 along the length direction of the handle 5. When the submersible pump is lifted from the liquid, the liquid flows along the first groove 51, reducing the resistance of lifting the submersible pump.

[0026] As Figure 2 and Figure 3 shown, the pump body 2 is used for installing an impeller inside. An arc-shaped concave hole 311 is formed on the inner surface of the pump body 2. The arc-shaped concave hole 311 is connected to the outlet pipe 4, and the radial cross-sectional area of the arc-shaped concave hole 311 gradually increases along the first circumferential direction. The first circumferential direction is the rotation direction of the impeller. The liquid in the pump body 2 enters the outlet pipe 4 along the arc-shaped concave hole 311 through the rotation of the impeller along the first circumferential direction, improving the liquid outlet efficiency.

[0027] The base 3 includes a body 31, a connecting column 34 and a bottom plate 36. The body 31 is detachably connected to the pump body 2 by screws. A third groove 312 is formed on one side of the body 31 facing the pump body 2. The third groove 312 is an annular groove, and the inner groove wall of the third groove 312 is higher than the outer groove wall. In this way, the liquid outside the body 31 is not easily introduced into the inside of the body 31 through the outer groove wall.

[0028] A guiding inclined surface is formed on the outer groove wall, which inclines from the inner groove wall towards the outer groove wall. The upper end of the inclined surface is the end close to the outer groove wall, and the lower end is the end far from the outer groove wall.

[0029] One end of the pump body 2 facing the seat body 31 is an annular end matching the third groove 312 and is embedded in the third groove 312. The pump body 2 is further provided with a guiding flange 22 whose inclination angle is adapted to that of the guiding inclined surface. Specifically, the inclined surface of the guiding flange 22 is parallel to the guiding inclined surface. The guiding flange 22 is located on the outer periphery of the pump body 2 and abuts against the top of the outer groove wall of the third groove 312.

[0030] In this way, during the upward lifting process of the submersible pump, the liquid flows along the guiding inclined surface and the guiding flange 22, reducing the resistance of the submersible pump during upward lifting. The pump body 2 is embedded in the third groove 312, improving the stability of the connection structure between the seat body 31 and the pump body 2.

[0031] A water inlet channel 32 is formed in the middle of the seat body 31. The water inlet channel 32 penetrates through the seat body 31. The water inlet channel 32 includes a water outlet and a water inlet. The water outlet is located above the water inlet. The diameter of the water outlet is larger than that of the water inlet, and the cross-sectional dimension of the water inlet channel 32 gradually increases in the direction from the water inlet to the water outlet.

[0032] The seat body 31 is further formed with a plurality of water passing ports 37. The plurality of water passing ports 37 are annularly arranged on the seat body 31 and are located below the water inlet. The seat body 31 is provided with a plurality of flow guiding plates 33. The plurality of flow guiding plates 33 are circumferentially annularly arranged below the water inlet channel 32. At least one flow guiding plate 33 is located between two adjacent water passing ports 37. The plurality of flow guiding plates 33 are integrally injection molded with the seat body 31 and are used to guide the liquid into the water inlet of the water inlet channel 32.

[0033] The seat body 31 is further provided with connecting columns 34. There are a plurality of connecting columns 34. One end of the connecting column 34 is connected to the seat body 31, and the other end is detachably connected to the bottom plate 36. A baffle 35 is arranged between the connecting column 34 and the seat body 31. The baffle 35 has the same orientation as the flow guiding plate 33, which is used to prevent large-volume sundries in the liquid from being stuck between the connecting column 34 and the seat body 31, and at the same time guide the liquid to flow towards the direction close to the water inlet. The bottom plate 36 is detachably connected to the connecting column 34 by screws and abuts against the flow guiding plate 33.

[0034] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
