Description

Sealing structure of dust removing unit in vacuum cleaner

The present invention relates to a vacuum cleaner, and more particularly, to a sealing structure of a vacuum cleaner dust collecting unit capable of stably sealing a connection pipe between a dust collecting unit performing dust collection by a centrifugal separation method and a vacuum cleaner body.

The vacuum cleaner is a device that collects the waste by filtering the dirt from inside the body by using the vacuum pressure formed by the vacuum motor installed inside the body, and then suctioning the air containing the foreign matter.

As a filter for filtering foreign substances to be sucked, a paper filter having a regular envelope shape has been generally used. Such a paper filter filters out foreign substances such as dust contained in the sucked air by passing air but leaving foreign substances such as dust inside.

However, in the vacuum cleaner having such a paper filter, when foreign matters accumulate in the paper filter by a long time or more, the suction power of the vacuum cleaner is lowered, and the paper filter must be replaced periodically. There was discomfort.

In order to alleviate this inconvenience, a vacuum cleaner for performing cyclone filtering has been proposed.

1 is a view illustrating a vacuum cleaner that performs a general cyclone filtering method.

Referring to FIG. 1, a vacuum cleaner includes a main body 1 having a suction means for sucking air in a room, a connection hose 5 made of a flexible material connected to communicate with an inside of the main body 1, and the connection hose. Extension tube (8) which is installed to communicate with the end of (5) and is adjustable in length, and suction nozzle (9) into which air containing foreign matter flows from the bottom surface by suction force generated in the main body (1).

In detail, the main body 1 is provided with a dust collecting unit 2 detachable from the rear side. The dust collecting unit 2 is a part for performing a cyclone dust collection therein after introducing air containing foreign matters sucked from the suction nozzle 9. In addition, an exhaust part 4 is formed at a side of the main body 1 through which air filtered with foreign matters is discharged from the inside of the dust collecting unit 2. In addition, a pair of wheels 3 for moving the main body are rotatably provided on the bottom of the main body 1. In addition, one side of the main body 1, a power cord for supplying power to the vacuum cleaner is installed, the power cord is installed so that it can be stored inside while being wound on a cord reel (not shown) inside the main body. .

In detail, the dust collecting unit 2 is formed with a handle 1a to be gripped by a user when detaching from the rear of the main body 1. And the upper surface of the main body 1, when moving the vacuum cleaner, the handle (1b) that the user can hold is formed.

It describes the operation of the general vacuum cleaner presented.

When the main body 1 is driven, the suction force is transmitted to the suction nozzle 9 through the connection hose 5 and the extension tube 8 by the suction force in the vacuum state formed therein. In this case, the suction force of the vacuum cleaner may be adjusted by a switch 7 installed at the handle part 6 connected to the upper part of the extension pipe 8.

And by the suction force, air containing foreign matter on the bottom surface to be cleaned, flows into the interior of the vacuum cleaner body 1 via the suction nozzle 9, the extension pipe 8, and the connecting hose (5). do. In the main body, dirt may be introduced into the dust collecting unit 2 and filtered by a predetermined filter and then discarded separately.

On the other hand, the conventional techniques related to the above-mentioned dust collecting unit and the Republic of Korea Patent Publication No. 10-2001-0087691, 10-2000-0041558, and 10-2000-0067037, etc. The same number of cyclone dust collecting units of the vacuum cleaner can be employed.

However, such a dust collecting unit has a disadvantage in that the user must grasp the dust collecting unit 2 formed on the rear surface of the cleaner body 1 by hand and pull it out. In addition, in order to perform such an operation, there is a problem that the user must approach the rear part of the main body 1. And after approaching the back of the vacuum cleaner main body 1, there existed the inconvenient points which grasp the dust collection unit 2 by hand, and must take out the dust collection unit 2 by the back. In addition, such a difficulty in mounting may occur in the same manner when the dust collecting unit is inserted.

In addition, since the dust collecting unit formed on the rear surface of the cleaner main body 1 is inserted and placed without a fixed structure, there is a problem that it can be easily pulled out by an impact applied from the outside. Furthermore, there is a problem in that air leakage may occur due to a gap in the insertion state of the dust collecting unit due to an impact from the outside and a gap in the connection pipe.

In addition, when the dust is leaked, since the dirt, such as dust, not only is collected in the dust collecting unit but also other components of the vacuum cleaner, there is also a problem that the vacuum cleaner becomes dirty.

The present invention has been proposed to solve the problems described above, and an object of the present invention is to propose a sealing structure of a vacuum cleaner dust collecting unit that enables the user to conveniently insert or remove the dust collecting unit in any direction.

In addition, the present invention, while using the vacuum cleaner, in the pipe connection portion between the dust collecting unit and the vacuum cleaner main body, to prevent the leakage of air to increase the suction efficiency of the vacuum cleaner, vacuum cleaner that can keep the vacuum cleaner clean An object of the present invention is to propose a sealing structure of a dust collecting unit.
