In our lives, various pump products are often accessible. The pump brings great trouble to us while providing convenience to us. For example, the booster pump used in water purification products has a serious trouble in generating vibration and noise during operation. Besides the vibration and noise generated by the pump body, the water flow at the water outlet of the pump also has vibration, and the vibration is extremely easy to conduct the vibration to a following load, so that the load generates resonance, and great noise is generated. In addition, the pressure of tap water in our home fluctuates at different times. Especially, in some high-rise buildings with multiple pressurization or some areas similar to Chongqing, the fluctuation of the water pressure of tap water is very large, so that water hammer impact can be caused to load aquatic products behind the tap water often, and the aquatic products are damaged due to serious or even destructive consequences of the products.

At present, products on the market mainly achieve the vibration reduction effect through buffer materials for the vibration reduction mode of a pump, for example, rubber pads, springs and the like are used, the vibration reduction effect cannot achieve the ideal effect of people, vibration is easily transmitted to other parts such as a shell of the product, and therefore a new water path vibration reduction structure needs to be researched.
