[0011] In the figure, 1. pump head; 2. motor part; 3. water inlet end; 4. water outlet end; 5. first impeller; 6. second impeller; 7. impeller disk; 8. blades; 9. water shoulder; 10. water throwing chamber; 11. mounting shaft; 12. adjusting nut; 13. guide block; 14. impeller shaft. DETAILED DESCRIPTION

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 Place, Figure 2 , Figure 3 The novel vortex pump comprises a pump head 1 and a motor part 2 arranged on a pump body, the pump head 1 is provided with a water inlet end 3 and a water outlet end 4 respectively, an impeller unit is arranged in the pump head 1, and the impeller unit is composed of a first impeller 5 and a second impeller 6 connected and combined, the first impeller 5 and the second impeller 6 both comprise an impeller disc 7 and a plurality of blades 8 formed on the impeller disc 7, the outer ring of the impeller disc 7 extends outward, and the inner wall of the outer end of the impeller disc 7 has a water shoulder 9 provided outward to prevent the water from running wildly and achieve a better diversion effect, and a water throwing device is formed between the first impeller 5 and the second impeller 6. Cavity 10, where water flows fully and is thrown outward. The middle part of the second impeller 6 has a mounting shaft 11 which protrudes axially outward and is used to mount the first impeller 5. Two adjusting nuts 12 for axially limiting the first impeller 5 are connected to the mounting shaft 11. The mounting shaft 11 is provided with external threads. The adjusting nuts 12 firstly play a limiting role, and secondly can also adjust the axial position of the first impeller 5. The distance between the two is different, and the water flow rate, water volume, etc. are all different, and the water outlet efficiency will also change accordingly. The distance can be adjusted according to different usage environments.

[0014] To further elaborate, a plurality of guide blocks 13 are formed on the blades 8 to increase the contact area with water, increase the water rejection rate and further improve the working efficiency.

[0015] To be more specific, the rear end of the second impeller 6 has an impeller shaft 14, which is connected to the shaft of the motor via a coupling.

[0016] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0017] Although this article uses more terms such as pump head 1, motor part 2, water inlet end 3, water outlet end 4, first impeller 5, second impeller 6, impeller disc 7, blade 8, water shoulder 9, water throwing chamber 10, mounting shaft 11, adjusting nut 12, guide block 13, impeller shaft 14, etc., it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
