[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0024] The figure marks in the drawings of the specification include: 1. impeller body; 2. impeller socket shell; 3. impeller blades; 4. cylindrical connecting part; 5. impeller shaft; 6. pin groove; 7. water outlet hole; 8. water inlet hole; 9. long impeller blades; 10. short impeller blades; 11. pull ring.

[0025] Example 1

[0026] like Figure 1 As shown, the utility model is a water pump impeller that can absorb water close to the ground, including an impeller body 1, an impeller socket shell 2 and an impeller blade 3. A cylindrical connector 4 is arranged on the top periphery of the impeller body 1, and the impeller body 1 is embedded in the impeller socket shell 2 through the cylindrical connector 4. An impeller shaft 5 for the transmission shaft to pass through is arranged at the center of the impeller body 1, and a pin groove 6 for fixing the impeller and the transmission shaft is arranged on the impeller shaft 5. A water outlet 7 and a water inlet 8 are arranged on the top and bottom of the impeller body 1, respectively.

[0027] like Figure 2 As shown, the impeller blades 3 are vertical at the water inlet and gradually rotate along the impeller body 1 to a horizontal upward arc shape at the water outlet. The top of the impeller blades 3 is a distance away from the top of the impeller body 1.

[0028] like Figure 3 As shown, the edge of the impeller body 1 to the horizontal section at the bottom center is in an arc shape, and gradually slopes inward from the outermost edge. The bottom center part of the impeller body 1 is solid, and has a certain height difference with the bottom edge. The bottom edge can be close to the ground at any time to ensure water absorption efficiency.

[0029] A pull ring 11 is also provided at the bottom of the impeller body 1. The height of the pull ring 11 is lower than the bottom edge of the impeller body 1 and is integrated with the center of the bottom of the water pump.

[0030] Example 2

[0031] like Figure 4 As shown, the difference between this embodiment and embodiment 1 is that the water inlet hole 8 is designed with an arc slope to facilitate water inlet.

[0032] Example 3

[0033] like Figure 5 As shown, the difference between this embodiment and embodiment 1 is that the impeller blades 3 include long impeller blades 9 and short impeller blades 10, and the long impeller blades 9 and the short impeller blades 10 are staggered, which can improve the performance of the impeller and increase the flow rate of the water pump.

[0034] The specific implementation process is as follows:

[0035] When in use, fix the transmission shaft of the motor on the pin groove 6 on the impeller shaft 5, start the motor, and the transmission shaft of the motor drives the impeller body to rotate. By utilizing the rotation of the impeller blades 3, water is sucked from the water inlet 8 and sent to the water outlet 7.

[0036] After use, when disassembling the impeller body 1, the pull ring 11 is pulled by a disassembly tool. The height of the pull ring 11 is lower than the bottom edge of the impeller body 1, which can prevent the protruding pull ring 11 from scratching the ground.

[0037] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
