Abstract

The invention provides an electric dust collector usable in both a rod type and a portable type. The electric dust collector has a whirlwind dust collection device capable of maintaining an absorption force, has a dust centrifugal separation function, is miniature and light, and is convenient to use. The electric dust collector has a dust collector main body. The dust collector main body has an electric fan, an absorption port and the dust collection device. The dust collection device is provided with a basically cylinderical outer cylinder, and an inner cylinder arranged in the basically cylinderical outer cylinder. The inner cylinder and the outer cylinder are roughly configured in a concentric manner. The outer cylinder is provided with an inflow port at the side part. The inflow port is communicated with one end of a guiding tube. The guiding tube is arranged in the dust collector main body and are open on two ends. The absorption port is arranged on the other end of the guiding tube. The guiding tube is arranged on the side part of the dust collection device. The absorption is arranged between the guiding tube and the dust collection device.

Description

technical field [0001] The present invention relates to electric vacuum cleaners. Background technique [0002] In recent years, the methods of electric vacuum cleaners have become diversified. In addition to the existing floor mobile vacuum cleaners and upright vacuum cleaners, there are self-supporting walking vacuum cleaners, vacuum cleaners for bedding cleaning, and vertical (pole) portable dual-purpose vacuum cleaners. vacuum cleaners etc. Among them, vacuum cleaners that can be used as both a stick type and a portable vacuum cleaner are generally called DC stick type vacuum cleaners, and many products are equipped with storage batteries such as nickel metal hydride batteries or lithium ion batteries. [0003] This kind of DC rod vacuum cleaner has the following structure. The electric blower is driven by a battery, and the dusty air sucked from the suction body is introduced into the main body of the vacuum cleaner. Exhaust from the main body of the vacuum cleaner. ...
