Air purifier and air feeding assembly thereof

Abstract

The invention relates to an air purifier and an air feeding assembly thereof. The air feeding assembly comprises a shell, a draught fan assembly and an electric energy input terminal, wherein the draught fan assembly and the electric energy input terminal are arranged inside the shell. An air inlet is formed in the bottom of the shell, and an air outlet is formed in the top of the shell. The draught fan assembly comprises an air flue shell. The air flue shell comprises a cylindrical part and a horn-mouth-shaped part, wherein the cylindrical part is connected with the air outlet, and the horn-mouth-shaped part is connected with the air inlet and becomes larger in the air flow direction. Thus, after air flow enters the air flue shell from the air inlet, the air flow firstly enters the horn-mouth-shaped part with the diameter becoming larger gradually and then enters the cylindrical part, the air flow flows in a diffusion manner, eddies cannot be generated at the part connected with the air inlet, noise generated by the eddies is avoided, and the experience effect of a user is improved. Furthermore, by means of the structure, the air speed can be increased, and the air purifying effect can be improved. The air feeding assembly is provided with the electric energy input terminal so that air feeding assembly and air purifying modules can be designed in a split manner, and thus the user can conveniently replace the air purifying modules according to self demands.

Description

technical field [0001] The invention belongs to the technical field of air purification treatment, and in particular relates to an air cleaner and an air supply assembly thereof. Background technique [0002] With the increase of air pollution, air purifiers are becoming more and more popular. Existing air purifiers mainly include a complete housing, in which a purification filter assembly and a fan assembly for sucking and discharging air are arranged, and an air inlet and an air outlet are arranged on the housing. When the air purifier is running, under the action of the fan assembly, the air enters the shell of the air purifier from the air inlet, and after being purified by the purification filter assembly, it is discharged through the air outlet, and the pollutants in the air are filtered out by the purification filter assembly to achieve The effect of air purification. Air purifiers can include PM2.5 removal filter components, formaldehyde removal filter components, ...
