Description

Vacuum cleaner {vacuum cleaner}

The present invention relates to a vacuum cleaner.

In a conventional vacuum cleaner, a blower chamber in which a blower is incorporated is disposed in a downstream portion of the main body, a dust collecting chamber for collecting and collecting solid matter such as dust is disposed in the upstream portion, and a connecting pipe provided at one end of the hose is connected Is provided at the upstream end of the main body. And the other end of the hose is provided with a distal end pipe having a grip portion at the time of cleaning. One end of the extension pipe is connected to the distal end pipe by a removable material, and the other end of the extension pipe is connected to a suction pipe Suction dart sockets are provided as removable materials.

In the conventional vacuum cleaner having such a structure, when the filter is used for a predetermined period of time, the filter disposed between the blower chamber and the dust collecting chamber is adhered with the solid material, so that the vacuum is not properly formed in the dust collecting chamber. In this case, the user manually flushes the solids attached to the filter to reload or replace the filter.

Such a filter cleaning operation or a filter replacement operation causes the user to touch the object with the hand, thereby causing a problem that it is treated as a very inconvenient and troublesome operation.

In order to solve such a problem, a solid material attached to the filter is shaken into the dust collecting room by vibrating or hitting the filter by the driving source of the blower, or the filtered air flow selectively flowing back into the blower room is selectively backwashed, There is a suggestion to shake it off.

However, such a method still requires a manual operation of discharging the solid material from the dust collecting chamber when a certain amount of solid matter is accumulated in the dust collecting chamber, thereby allowing the user to touch the dislike of the dust such as dust, It is still being treated as a very uncomfortable and cumbersome task.

In addition, when the vacuum cleaner is applied to a portable vacuum cleaner in which the vacuum cleaner can be attached to the shoulder to remove leaves falling on the street, the volume of the collected leaves is large and the volume of the vacuum cleaner is increased, The conventional vacuum cleaner has a problem in that it is unsuitable for portable use.

In order to solve this problem, when the volume of the dust collecting chamber is made small, the amount of the dust that can be collected by the dust collecting chamber can be reduced and the leaves collected in the dust collecting chamber are quickly filled into the dust collecting chamber. The conventional vacuum cleaner has a problem that it must be manually discharged from the main body.

In order to solve such a problem, a suction chamber provided inside the cleaner main body is excluded, only a suction chamber is provided in the main body, a fan provided in the suction chamber is operated to suck solids outside the main body into the suction chamber without filtration, It is possible to cause the problem that the solid matter causing the contamination sticks to the blade of the fan and it is difficult to form the negative pressure by the fan.
