Problems solved by technology

[0002] The main noise sources of the horizontal vacuum cleaner are the floor brush, the air intake, the dust cup and the air outlet of the main engine. The existing horizontal vacuum cleaner does not have any noise reduction design, and the main structure is directly designed to reduce noise, but the noise reduction effect of this method is limited. , resulting in excessive noise when the vacuum cleaner is in use, which greatly affects the user's experience and comfort

Abstract

The invention provides an inlet pipe and vacuum cleaner. The inlet pipe comprises an inner pipe, and a muffling hole is arranged on the wall of the inner pipe; the first outer tube is sleeved on the inner tube, and a first muffling cavity is formed between the inner tube and the first outer tube. The intake pipe provided by the invention is equivalent to a composite micro-perforated silencer, andan inner tube with a sound-absorbing hole (micro-perforation) and a first outer tube are arranged to form a first silencing cavity, so that an air intake pipe is introduced into the casing. The airflow can reduce the regenerative noise of the airflow through the silencing hole during the flow process, and improve the noise level of the whole machine and the intake part when the vacuum cleaner is used, especially the high frequency noise. At that same time, the first muffle cavity formed between the inn tube and the first outer tube can also absorb and isolate part of the noise to improve the overall noise level and the user experience and comfort.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an air intake pipe and a vacuum cleaner. Background technique [0002] The main noise sources of the horizontal vacuum cleaner are the floor brush, the air intake, the dust cup and the air outlet of the main engine. The existing horizontal vacuum cleaner does not have any noise reduction design, and the main structure is directly designed to reduce noise, but the noise reduction effect of this method is limited. , resulting in excessive noise when the vacuum cleaner is in use, which greatly affects the user's experience and comfort. Among them, the ground brush, air intake, and dust cup are the noise sources of the air intake. The main noise comes from the airflow. If a better structure is designed to reduce the noise of the air intake, it will become an important issue for the vacuum cleaner. Contents of the invention [0003] In order to solve at least one of th...
