Description

Noise reduction fan assembly Technical Field The utility model relates to the technical field of electric appliances, in particular to a fan assembly. Background At present, small household cleaning appliances, such as dust collectors, floor sweeping robots, floor washing machines, hand suction machines and the like, use fans as power sources to generate suction air flow and utilize the suction air flow to clean dust, liquid, mites and the like on surfaces to be cleaned, such as floors, bed surfaces and the like. When a user uses the equipment, the fan works due to factors such as mechanical vibration, air flow disturbance and the like, so that the equipment has loud using noise, and the user has low using comfort. We have therefore proposed a noise reducing fan assembly in order to solve the problems set out above. Disclosure of utility model The utility model aims to provide a noise reduction fan assembly, which solves the problems that the existing fans in the market at present, which are proposed by the background technology, work due to factors such as mechanical vibration, air flow disturbance and the like, cause larger equipment use noise and are not high in use comfort level of users. In order to achieve the purpose, the noise reduction fan assembly comprises a shell, wherein a net cover and a fan are arranged in the shell, the net cover is arranged between the shell and the fan, a shell air inlet and a shell air outlet are formed in the shell, the fan is provided with a fan air inlet and a fan air outlet, the shell air inlet is communicated with a fan air inlet runner, the shell air outlet is communicated with a fan air outlet runner, and the net cover is arranged in a runner between the shell air outlet and the fan air outlet. Preferably, the housing inlet and the housing outlet are located on the same side of the housing. Through adopting above-mentioned technical scheme, through the setting of shell air inlet and shell gas vent same one side to the screen panel is convenient for arrange in the shell. Preferably, the mesh enclosure is circumferentially arranged on the fan. Through adopting above-mentioned technical scheme, through encircling the screen panel and setting up in the fan to make the air-out of fan fall by the screen panel and make an uproar. Preferably, the mesh enclosure comprises a first mesh enclosure and a second mesh enclosure, and the first mesh enclosure and the second mesh enclosure are arranged substantially vertically. Preferably, the first mesh enclosure is connected with the second mesh enclosure. Through adopting above-mentioned technical scheme, connect through first screen panel and second screen panel is general perpendicular to the screen panel of being convenient for arranges in the shell. Preferably, the mesh is arranged on the mesh enclosure, and the mesh is round. Through adopting above-mentioned technical scheme, fall the wind channel through circular shape mesh on the screen panel and make an uproar. Preferably, the number of the exhaust openings of the shell is plural. Preferably, the mesh cover covers the whole runner between the exhaust port of the shell and the air outlet of the fan. Through adopting above-mentioned technical scheme, through setting up a plurality of shell gas vents and screen panel and covering whole runner, be favorable to reducing the noise when the air current is discharged. Compared with the prior art, the noise reduction fan assembly has the beneficial effects that the mesh enclosure is arranged in the flow channel between the exhaust port of the shell and the air outlet of the fan, so that the airflow in the flow channel is conveniently rectified, and the noise in the whole assembly is reduced.
