Description

Barreled water pump

Technical Field

Background

In the prior art, barreled water pumps mainly utilize miniature diaphragm pumps to accomplish the extraction of water. The miniature diaphragm pump generally comprises a pump body, a diaphragm, a pump cover, an inlet and an outlet, and the like, wherein an air inlet chamber and an air outlet chamber are arranged in the pump body, the air inlet chamber and the pump cover are sealed through a diaphragm, and the pump cover is in spherical fit with the pump body. The inlet and the outlet are generally connected by adopting a thinner pipeline, when the miniature diaphragm pump works, the pump cover moves up and down along the pump body, so that pressure difference is generated between the inside and the outside of the pump body, and water enters the pump chamber through the water inlet pipe and is discharged through the water outlet pipe under the action of the pressure difference.

However, the prior art pump has the following disadvantages:

1) The energy efficiency is low, and the micro diaphragm pump is generally low, mainly because a sufficient pressure difference needs to be generated between the pump body and the pump cover to drive the water flow, and the pressure difference is larger than that of a large pump, so that more energy is consumed. In addition, friction and drag are easily generated inside the micro diaphragm pump, which results in energy loss.

2) The small flow, micro-diaphragm pumps, due to their structural and dimensional limitations, typically have a flow rate of between 1 and 1.5 liters per minute, which results in a longer time for drawing a certain amount of water, for example about 15 seconds for drawing a cup of 300 milliliters of water, which is relatively long and inconvenient to use.

3) When the micro diaphragm pump works, the pump cover and the pump body can generate larger impact noise, particularly in the night or in the environment needing to be kept quiet, the micro diaphragm pump can greatly puzzle people, and even people or children can get noisy when serious.

In summary, the existing water pump has the defects of low energy utilization efficiency, small flow, high noise and the like in the using process, and needs to be improved and developed.
