Multi-blade electric fan with air purification device and manufacturing method thereof

Abstract

The invention provides a multi-blade electric fan with an air purification device and a manufacturing method thereof. The multi-blade electric fan comprises a motor and is further provided with a 360-degree rotating air supply device. A circular inner barrel is arranged in a barrel body of the 360-degree rotating air supply device, and a rotating gear and a central spindle are arranged in the inner barrel. A six-plate bearing is arranged on the sunken area of the outer bottom portion of the inner barrel, and the bearing is provided with an air speed control line, a power positive electrode and a power negative electrode in a welding mode. The upper portion and the lower portion of the periphery of the inner barrel are each provided with a bearing, and a six-plate bearing is arranged in the bottom of an outer barrel in the same way. The outer barrel is provided with an air speed control line, a power positive electrode and a power negative electrode which are the same as those of the inner barrel in a welding mode. A control table, a support tube and a base are arranged on the lower portion of the outer barrel. A barrel sealing cover is provided with the motor. Fan blades, a front fan mesh, a photocatalyst filtering layer, a rear cover nut, a rear fan mesh and a motor shaft are arranged on the left side of the motor. A gear case, a head shaking pull cover, a rotating gear and a longitudinal shaft are arranged on the right side of the motor. The right side of the gear case is provided with elements the same as that of the left side of the motor and is provided with a circuit. An interface of a power supply is connected with the all-dimensional rotating air supply device. The multi-blade electric fan is economical and practical.

Description

technical field [0001] The invention relates to electric fan all-round air supply equipment, in particular to the field of manufacturing electric fans for 360-degree air supply used in urban and rural families, restaurants, entertainment and office places. Background technique [0002] Electric fans were popular in the 1980s and 1990s, but due to the competition and squeeze of air conditioners, the market once shrank. Today's electric fans have undergone earth-shaking changes in technology, design, and market concepts compared with the past. It is no longer just a small household appliance for ventilation and disinfection, but the innovation in new functions has opened up a new market for the fan. The innovation has prevented the fan from colliding with the air conditioner in competition. The air conditioner is mainly "cooling down", while the The electric fan then has the dual functions of "natural defense" and "ventilation", and the electric fan utilizes its own effect dif...
