Noise Mechanisms and Noise Reduction Analysis of Water Absorption System of Commercial Cleaning Robots
In response to the noise issue of the water absorption system,this article takes the water absorption system of a certain commercial cleaning robot as an example,through spectrum analysis and CAE simulation anal-ysis,the noise reduction scheme of the water absorption system noise sources mainly distributed in the interior of the water absorption motor,the inlet connection of the water absorption pipeline and the outlet of the air outlet pipeline is studied.and a prototype is manufactured for verification.The experimental results show that the overall noise of the prototype is reduced by 6.5 dB by wrapping a buffer pad and outer cover around the suction motor,and appropriately increasing the diameter of the water pipeline inlet connection and the outlet pipeline.After opti-mization,the noise reduction effect is significant.
