Problems solved by technology

[0004] The motor body can drive the fan to rotate in the working state, so that the air enters the air duct from the air inlet and flows out of the air duct through the air outlet. However, the air will generate noise during the flow in the air duct, which reduces the quality of the vacuum cleaner.

Abstract

The invention provides a channel structure and a dust collector. The channel structure comprises a fan unit, a shell and a flow guiding part, the shell is provided with an air inlet and an air outlet,an air duct is formed in the shell, the air duct comprises a first channel, a second channel and a third channel, the air inlet, the first channel, the second channel, the third channel and the air outlet sequentially communicate with one another, the fan unit is arranged in the air duct, in a started state, the fan unit enables air to enter the air duct from the air inlet and sequentially pass through the first channel, the second channel, the third channel and the air outlet to flow out of the air duct; the diameter of the second channel is less than that of the first channel so as to converge the air flowing from the first channel to the second channel; and the flow guiding part is arranged in the third channel and used for dispersing the air flowing from the second channel to the third channel, and thus the air can flow in the third channel in different directions. The using quality of the channel structure and the dust collector can be improved.

Description

technical field [0001] The invention relates to motor equipment technology, in particular to a channel structure and a vacuum cleaner. Background technique [0002] With the advancement of science and technology and economic society, vacuum cleaners are widely used in people's daily life.
