The invention discloses a base and a bladeless fan. The base comprises a shell, a power system and a noise reduction structure; the shell comprises a wall, and an air inlet is formed in the wall; the power system is arranged in the shell and used for sucking in air from the air inlet and building air flow; and the noise reduction structure is arranged in the shell and installed on the outer side of the lower end of the power system, the noise reduction structure is provided with a first noise reduction cavity and a first noise inlet communicated with the first noise reduction cavity, the noise reduction structure comprises a top shell opposite to the first noise inlet, and the top shell is provided with a plurality of through holes communicated with the first noise reduction cavity. In the above base, when the power system works, noise generated by the fact that the air is sucked into the shell through the air inlet can be led by the power system to the interior of the first noise reduction cavity through the first noise inlet and is reflected and absorbed by the first noise reduction cavity to be eliminated; meanwhile, the above noise reduction effect can be strengthened through the noise reduction structure with the multiple through holes; and in this way, the noise formed when the power system works is effectively reduced.
Description
technical field [0001] The invention relates to the field of household electrical appliances, in particular to a base and a bladeless fan. Background technique [0002] In the related art, the existing bladeless fan includes a base. The base includes a shell and a power system arranged in the shell. The housing is formed with air intakes through which the powertrain draws in air and establishes air flow during operation. However, the noise emitted by the power system is relatively large and can be diffused outward through the air intake, resulting in relatively high noise from the bladeless fan. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention needs to provide a base and a bladeless fan. [0004] A pedestal according to an embodiment of the present invention is used for a bladeless fan, and the pedestal includes: a casing, the casing includes a wall,...
