Therefore, the dust bag must be cleaned or replaced frequently, and replaced and cleaned. It is necessary to disassemble the whole machine, which is very inconvenient for the user. For this purpose, the utility model patent of the patent number ZL00216307.1 "a dust-free bag vacuum cleaner" (publication number CN2411754Y) discloses a vacuum cleaner that does not need to use a dust bag, the dust-free bag vacuum cleaner includes a main body and The dust collecting device is disposed outside the main body and is detachably connected with the main body, and mainly comprises a casing and a dust collecting cylinder which is detachably connected to the casing, and one side of the casing is open a dust suction hole connected to the dust suction pipe, and a dust sedimentation device is arranged in a space formed by the cover shell and the dust collecting cylinder; wherein the dust sedimentation device is composed of a filter cylinder, an outer settling cylinder and an inner settling cylinder, wherein the inner settling cylinder is In the shape of a funnel, the upper end of the mouth is connected to the casing, and the air outlet hole in the center of the casing is inserted into the space enclosed by the two, and the lower end of the inner settling cylinder has a gap between the dust collecting cylinder and the filter cylinder. The upper part of the inner settling cylinder is provided with a gap between the two, and a plurality of filtering holes are opened in the corresponding peripheral wall of the two, and the outer settling cylinder surrounds the inner settling cylinder below the filter cylinder, and the lower end and the set Dust cartridge is integrated, the cover The dust collecting hole on the shell communicates with the outer settling chamber surrounded by the filter cylinder, the outer settling cylinder and the dust collecting cylinder, and the space inside the inner sinking cylinder and the space between it and the outer settling cylinder constitute an internal settling chamber. When in use, the fan of the vacuum cleaner rotates to form a negative pressure in the dust collecting cylinder, and then the dust-intake airflow enters through the dust suction pipe from the tangential suction port of the dust collecting device cover, and rapidly flows in along the inner wall of the dust collecting cylinder to form The large-circle airflow swirls, and the large-sized dust is blocked in the outer settling chamber, and slides down the inner wall of the dust collecting cylinder to the bottom of the drum. The fins disposed on the inner wall of the dust collecting cylinder and the fins disposed on the outer wall of the outer settling cylinder block the swirling Continue to flow, so that the falling dust will not be blown away again; the small dust will enter the inner settling cylinder through the small hole in the filter cylinder and continue to centrifuge, because the cavity inside the inner settling cylinder is small, so The airflow rotation speed is increased, and since the inner settling chamber is a large funnel shape, the rotation speed is further accelerated as the air swirls downward, and finally the inner wall of the inner settling cylinder Sliding into the bottom of the funnel, and there is no air flow at the bottom of the funnel, so the falling dust will not be blown up again. Compared with the conventional vacuum cleaner with the dust bag as the dust collecting device, the utility model provides a vacuum cleaner with a new structure, and no dust collecting bag is provided, and the external dust collecting device is not only convenient for disassembly and assembly, but also convenient for cleaning. Moreover, the dust sedimentation device and the like are designed such that the sucked dust swirls and settles in the dust collecting device without floating, and the dust collecting effect is better.
