AI Technical Summary

Technical Problem

In the existing toilet design, the water pressure is insufficient when the tap water is flushed directly, resulting in poor erosion effect and waste of water due to unstable water pressure.

Method used

A miniature water pump is designed, including a pump body, a pump cover and a motor assembly. The pump cover has a water cavity and anti-evacuation water inlet holes to prevent evacuation and double flushing with a pneumatic device.

Benefits of technology

It is achieved to prevent the water pump from being evacuated in various application scenarios, improve the efficiency and flushing effect of the water pump, and avoid the erosion weakness and water waste caused by insufficient water pressure.

Abstract

A micro water pump, a toilet flushing system and a toilet. The micro water pump comprises a pump body, a pump cover and a motor assembly, wherein the motor assembly comprises a stator and a rotor, wherein the stator is arranged in the pump body, and the rotor is arranged in an inner cavity surrounded by the stator; the pump cover has a water cavity, wherein the water cavity has an impeller connected to one end of the rotor, and the pump cover also has a water inlet axially connected to the water cavity and a water outlet circumferentially connected to the water cavity; the pump cover is characterized in that the pump cover also has an anti-vacuum water inlet hole, wherein the anti-vacuum water inlet hole passes through the pump cover and is connected to the water cavity. The micro water pump can avoid the vacuum problem.
