Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1-3, a water pump with high water outlet speed is provided, which comprises a tank 1, an impeller 2, a bottom cover 3 and a water outlet pipe assembly. Impeller body 2 includes blade 21, the outlet pipe subassembly includes stereoplasm outer tube 8, stereoplasm outer tube 8 and box 1 integrated into one piece, 1 bottom of box is equipped with the holding tank 11 that is used for holding blade 21, and blade 21 is at 11 rotations of holding tank, 3 lids of bottom are established in 1 bottom of box and bottom 3 is equipped with the through-hole 31 relative with

holding tank

11, 8 lower extremes of stereoplasm outer tube and holding tank 11 intercommunication and stereoplasm outer tube 8 are equipped with exhaust hole 81 with the just right lateral wall of holding tank 11.

Therefore, the water pump comprises a box body 1, an impeller body 2 and a hard outer tube 8, wherein the bottom of the box body 1 is provided with an accommodating groove 11 for accommodating the blade 21, water is conveyed by the blade 21 and flows into the accommodating groove 11 from the through hole 31, then flows to the hard outer tube 8 from the accommodating groove 11, the hard outer tube 8 is over against the side wall of the accommodating groove 11 to be provided with an exhaust hole 81, and when the blade 21 rotates, gas in the box body 1 and at the bottom of the hard outer tube 8 can be rapidly exhausted before water is discharged, so that the air pressure in the box body 1 is reduced, and the water outlet speed of.

Preferably, as shown in fig. 4, the water outlet pipe assembly further comprises a hard inner pipe 4, a flexible hose 5, an upper end cover 6 and an annular lower base 7. The hard inner tube 4 is slidably inserted into the inner wall of the hard outer tube 8, the hard inner tube 4 and the hard outer tube 8 can be matched through a dovetail groove, a lower boss 41 is arranged on the outer tube wall at the lower end of the hard inner tube 4, an annular groove 42 is formed in the lower boss 41, the annular lower base 7 is sleeved on the hard inner tube 4 and is slidably embedded in the annular groove 42, and the annular lower base 7 can rotate in the annular groove 42. The inner pipe wall at the upper end of the hard inner pipe 4 is provided with internal threads. The upper end cover 6 is provided with an external thread column 61 and an upper boss 62 fixedly connected to the upper end of the external thread column 61, and the external thread column 61 is inserted into the hard inner tube 4 and is in threaded connection with the hard inner tube 4, so that the telescopic hose 5 is fixed between the hard outer tube 8 and the hard inner tube 4.
