Abstract

The invention discloses a base and a bladeless fan. The base comprises a shell, a power system and a silencer, the shell comprises an outer wall, the power system is arranged inside the outer wall, the silencer is arranged inside the outer wall, an air inlet is formed in the outer wall, and the power system is used for inhaling air through the air inlet to form airflow; the silencer comprises a first muffling cavity and a first sound entrance, wherein the first sound entrance is communicated with the first muffling cavity and located between the power system and the air inlet. When running, the power system is used for introducing noise, generated by inhaling of the air to the inside of the outer wall through the air inlet, into the first muffling cavity through the first sound entrance, and then the first muffling cavity is used for reflecting and absorbing the noise so as to eliminate the noise, at the same time, the noise generated by the running of the power system can be introduced into the first muffling cavity through the first sound entrance in advance before diffusing toward the air inlet and is reflected and absorbed by the first muffling cavity.

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] Existing bladeless fans include 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] The base according to the embodiment of the present invention can be used for a bladeless fan. The base includes a housing, a power system and a noise reduction component. The hous...
