Filtration system for separation of whirlwind and dust storage, hand-held vacuum cleaner and rod-type vacuum cleaner

Abstract

The invention discloses a filtration system for separation of whirlwind and dust storage, a hand-held vacuum cleaner and a rod-type vacuum cleaner. Through relatively independent arrangement of a duststorage chamber and a dust-air separation device, the dust-air separation device is unlikely to be blocked, the dust storage space of a dust cup is increased, and the dust collection amount is increased.

Description

technical field [0001] The invention belongs to the technical field of vacuum cleaner structure design, and in particular relates to a filter system for separating cyclone and ash storage, a hand-held vacuum cleaner and a stick-type vacuum cleaner. Background technique [0002] The vacuum cleaner is a cleaning appliance that uses the motor to drive the blades to rotate at high speed, and generates air negative pressure in the sealed housing, thereby sucking the dust into the ash storage room, and discharging the filtered air out of the fan at a very high speed. The vacuum cleaner is based on its structure Different forms can be divided into horizontal vacuum cleaners, rod vacuum cleaners and hand-held vacuum cleaners. In specific use, different cleaning devices can be selected according to different cleaning needs, which is convenient and fast, and has low labor intensity. [0003] At present, vacuum cleaners are gradually developing in the direction of miniaturization, ligh...

AI Technical Summary

Problems solved by technology

[0003] At present, vacuum cleaners are gradually developing in the direction of miniaturization, light weight, and convenience. The overall volume of the vacuum cleaner is relatively reduced, so the volume of the dust cup is also relatively small, especially for hand-held vacuum cleaners. A small part of the body, the amount of dust collection is small, only suitable for ordinary household, office cleaning, etc.

Moreover, the cyclone of the traditional vacuum cleaner is placed inside the dust cup, occupying a certain amount of dust cup space, the ash storage space is further reduced, and the dust collection capacity is limited

In addition, the whirlwind of the traditional vacuum cleaner is formed inside the dust cup, and the whirlwind space is connected to the dust storage space. It is easy to turn up the dust in the dust cup, and there is a problem of dust sucking back. When the dust inside the dust cup accumulates to a certain extent, it needs to be cleaned in time , otherwise it will easily cause excessive dust to block the filter screen cover, affecting the filtration efficiency and effect, and cannot make full use of the limited dust cup space
