Description

Technical Field

[0001] The utility model relates to the technical field of water purification, in particular to a water purifier. Background Art

[0002] With the improvement of people's living standards, purified water is often needed in daily life, so the use of water purifiers is becoming more and more widespread. Existing water purifiers generally use reverse osmosis filters for water purification.

[0003] When the water purifier is working, the pump body and the filtration system are prone to generate noise. To address this problem, the Chinese utility model patent with patent number CN202221130895.7 (publication number CN217841972U) discloses a "fixed connection structure for a booster pump for a water purifier", which includes a base and a booster pump. A vertically fixed U-shaped rib plate bracket is provided on the base. The booster pump is arranged vertically and the two side half sets are assembled in the groove recessed in the middle of the U-shaped rib plate bracket, and the top of the booster pump is fixed to the upper end of the U-shaped rib plate bracket by a shock-absorbing connector. The booster pump is fixed in a semi-suspension manner to effectively prevent the vibration from being transmitted to the shell of the water purifier through the base, thereby effectively reducing vibration and shielding the noise generated by vibration.

[0004] Although this patent adopts vibration reduction measures for the pump body, if the structure of the filtration system is over-connected to the whole machine, it is easy to cause resonance between other sheet metal shells (such as the side walls of the box) when the pump is working, thereby generating noise.
