Noise reduction structure, stabilized pressure pump mounting assembly and water purifier

Abstract

The invention relates to the technical field of water purifiers, in particular to a noise reduction structure, a stabilized pressure pump mounting assembly and a water purifier. The noise reduction structure comprises an inner shell, an outer shell and a concave-convex structure, wherein a stabilized pressure pump is suitable for being arranged in the inner shell, and the inner shell is provided with a plurality of micro-perforated holes; the outer shell is arranged on the outer side of the inner shell, and a first cavity is formed between the outer shell and the inner shell; and the concave-convex structure is arranged on the outer surface of the inner shell and / or the inner surface of the outer shell. Noise sound waves generated when the stabilized pressure pump works can be transmittedinto the first cavity between the outer shell and the inner shell through the micro-perforated holes in the inner shell, and when part of the sound waves pass through the micro-perforated holes, the micro-perforated holes obtain sufficient acoustic reactance to complete the attenuation of the sound waves through the friction with the wall faces of the holes, and after the sound waves enter the first cavity, the sound waves are continuously reflected in the first cavity through the concave-convex structure, and meanwhile, the sound waves resonate with an air layer between the inner shell and the outer shell, so that the attenuation of sound wave energy is further completed, and therefore, the noise transmitted from the stabilized pressure pump to the outside can be reduced.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a noise reduction structure, a pressure stabilizing pump installation component and a water purifier. Background technique [0002] With the continuous improvement of people's living standards, issues such as water quality and health have gradually become the focus of people's attention, and more and more water purifiers have entered the homes of ordinary users. As the core component of the water purifier, the pressure stabilizing pump needs to pressurize the pretreated water into the reverse osmosis membrane for filtration, and the stabilizing pump has a lot of noise and vibration during operation, which makes the water purifier produce relatively Loud noise and vibration not only affect the quality of the product and cause bad experience, but also reduce the market competitiveness of the product. Contents of the invention [0003] Therefore, the technical problem to ...
