Dust collection device with simplified barrel nut structure

Abstract

The invention discloses a dust collection device with a simplified barrel nut structure. The dust collection device comprises a dust collection barrel, a cyclone separator and a filter which is horizontally arranged inside the barrel body of the cyclone separator, wherein a barrel nut is arranged on the inner side at the closed end of the cyclone separator, and is integrated with the barrel body of the cyclone separator. According to the dust collection device with the simplified barrel nut structure, the barrel nut is formed by integrating with the barrel body of the cyclone separator, and the structure in such a way has the advantages that: firstly, a cylinder, screws and other original components are reduced in such a structure, and the cost for developing dies of corresponding components is reduced; secondly, a gap is not reserved between the barrel nut and the barrel body of the cyclone separator, so that dust cannot be accumulated, and the device is easier to clean; and thirdly, fixation does not require bolts, so that manual operation is reduced, the rejection rate of products is reduced, and the barrel nut can be ensured to be positioned on the same central axis with the filter.

Description

technical field [0001] The invention belongs to the field of vacuum cleaners, and in particular relates to a dust collecting device with a simplified cylindrical cap structure which integrates a cylindrical cap on the inner surface of a closed end of a cyclone separator and a barrel of the cyclone separator. Background technique [0002] Vacuum suction is a cleaning and sanitary appliance used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body of the vacuum cleaner. The suction pipeline includes a suction head, a suction pipe and a suction hose. The head has a suction port opening downwards and communicates with the air inlet of the fan inside the vacuum cleaner body through a dust suction pipe and a dust suction hose. [0003] When the vacuum cleaner is running, the motor d...
