BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collecting unit of a vacuum cleaner, and more particularly, to a dust collecting unit of a vacuum cleaner for facilitating coupling and detachment of a dust collecting unit.

In general, a vacuum cleaner is a device that sucks air containing a foreign material by using a suction force generated by a vacuum motor mounted inside the main body, and then filters the foreign material inside the main body.

Such a vacuum cleaner may be distinguished by a canister method in which a suction nozzle for allowing a foreign material to be sucked in is largely provided separately from the main body and connected by a connecting pipe, and an upright method in which the suction nozzle is integrally formed with the main body.

On the other hand, the dust collecting unit mounted on the cyclone vacuum cleaner uses a cyclone principle, so that the foreign matter contained in the sucked air and rotated together is separated and collected from the air, and the air from which the foreign matter is removed is discharged to the outside of the cleaner Device.

In order to improve dust collection performance, in recent years, a multi-cyclone dust collection unit having a cyclone unit composed of a plurality of orders is used.

In addition, first and second foreign matter storage portions in which foreign matter separated by the first and second cyclone portions are stored are formed in the dust collecting body.

Such a multi-cyclone dust collecting unit has a dust collecting body and each cyclone portion combined with each other to form one complete article.

By the way, according to such a conventional dust collecting unit, since the combination of a plurality of articles is made by a separate coupling structure, the structure of a dust collection unit becomes complicated, and there exists a problem which is expensive in order to form a coupling structure.

In addition, since the coupling of the dust collecting unit has to be performed by each coupling structure, there is a troublesome problem for the user.

The present invention has been proposed to solve the above problems, and an object of the present invention is to propose a dust collecting unit of a vacuum cleaner that can be easily combined and separated.

In addition, an object of the present invention is to propose a dust collecting unit of a vacuum cleaner that is capable of engaging and separating the dust collecting unit by a single coupling member.

Dust collecting unit of the vacuum cleaner according to the present invention for achieving the object as described above is a dust collecting body is formed a space in which the foreign matter is stored; A cyclone unit coupled to an upper side of the dust collecting body and separating foreign matters from inhaled air; An upper cover provided at an upper side of the cyclone unit to guide air from which foreign matter is separated from the cyclone unit; And a detachable member coupled to the cyclone unit to allow the cyclone unit and the upper cover to be coupled and the cyclone unit to the dust collecting body at the same time.

Hereinafter, with reference to the drawings will be described a specific embodiment of the present invention. However, the spirit of the present invention is not limited to the embodiments presented, and those skilled in the art who understand the spirit of the present invention can easily suggest other embodiments within the scope of the same idea.

Therefore, as shown in FIG. 6, when the user pulls the upper side of the detachable member 200 to detach the upper cover 180 from the cyclone unit 120, the upper portion of the detachable member 200 is separated. It is bent to the user side (or the outside of the dust collecting unit). When the upper side of the detachable member 200 is bent toward the user side, the upper locking portion 232 inserted into the locking groove 182 is removed. Then, the upper cover 180 is in a removable state.

Meanwhile, as illustrated in FIG. 7, when the user pulls the lower side of the detachable member 200 to separate the cyclone unit 120 from the dust collecting body 110, the lower portion of the detachable member 200 is a user. It will bend to the side (or the outside of the dust collecting unit). Then, when the lower portion of the detachable member 200 is bent to the user side, the locking action of the locking projection 116 and the lower locking portion 134 is released. Then, the cyclone unit 120 is in a detachable state.

As such, the upper cover 180, the cyclone unit 120, and the dust collecting body 110 are coupled by a single detachable member 200. In order to enable such coupling, the locking groove 182 and the upper locking portion are provided.
