Description

Shock-absorbing noise-reducing structure of booster pump and purified water machine thereof

Technical Field

The utility model relates to the technical field of purified water machines, in particular to a shock absorption and noise reduction structure of a booster pump for a purified water machine.

Background

The pure water machine can generate vibration and noise in the use process, and the main root of the vibration and noise is a booster pump in the pure water machine. The booster pump works through the structural principle that a plurality of water absorption cavities distributed along the periphery of the pump body absorb water in turn and water is output from the middle water outlet cavity, namely, the booster pump has a structure with single-side water inlet and central water outlet, so that the booster pump eccentrically works to become a vibration body. The noise generated by the vibration seriously disturbs the use of users and directly affects the quality of the water purifier.

In order to eliminate the defects, the booster pump on the existing pure water machine is often fixed on the pure water machine through a damping rubber pad by screws, and the damping effect can be achieved to a certain extent because the rubber is made of soft materials. However, since the booster pump is only jacked up by four rubber pads, the booster pump cannot be completely fixed, and the fixed booster pump still can shake. Therefore, the noise reduction structure still cannot effectively prevent vibration of the booster pump and water machine resonance caused by the vibration of the booster pump. Meanwhile, the booster pump can generate heat during operation, if heat generated by heating cannot be timely discharged, vibration and noise of the booster pump after heating can be increased, and the service life of the booster pump can be shortened. Therefore, the shock absorption and noise reduction structure for the existing booster pump is still to be further improved.
