Abstract

The invention discloses a water pump evacuating assist device comprising a water pump body, a fixing base and an adjusting base. The fixing base is arranged at the bottom of the water pump body; the adjusting base is of a barrel shape; and distance between the fixing base and the adjusting base can be adjusted. A rotating shaft with impellers is arranged in the fixing base. The fixing base is provided with a bottom water inlet. A water inlet of the lateral portion is arranged on the lateral wall of the adjusting base; and a water inlet of the bottom portion is arranged on the bottom surface of the adjusting base. A sealing ring butted against the bottom surface of the adjusting base in a sealing manner is mounted at the position of the water inlet of the fixing base. When the adjusting base is open, a water pump can pump water normally like the other ordinary water pumps; and when the adjusting base is closed, the sealing ring is butted against the bottom surface of the adjusting base in a sealing manner, so that water flow can be prevented from entering the water pump via the water inlet of the lateral portion of the adjusting base, evacuating capability of the impellers is improved, leakage is avoided, and purposes of completely evacuating water by the bottom water inlet of the fixing base are achieved.

Description

technical field [0001] The invention belongs to the field of water pumps, and in particular relates to a water pump vacuuming auxiliary device. Background technique [0002] Existing water pumps can only complete simple pumping work when in use, and cannot be adjusted according to actual needs. For example, when the water pump is faced with more requirements for use, it is necessary to allow the water pump to be used for normal water pumping and to allow the water pump to completely pump the water Dry, the existing water pump can only be used for normal pumping, and cannot achieve the effect of completely draining the water. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a water pump vacuum auxiliary device which can not only be used for normal water pumping, but also increase the vacuum pumping ability of the water pump to completely dry the water. [0004] The technical solution adopted in the present inventi...
