10 is a vacuum cleaner equipped with a cleaner head according to another embodiment of the present invention. Not shown FIG. 1 to FIG. 9.

The vacuum cleaner 1B is provided such that the cleaner head 100B provided to suck foreign matters on the surface to be cleaned (not shown, floor B) by the suction force of air and the foreign matter sucked through the cleaner head 100B are collected. And a cleaner body 10B.

A connection pipe 20B and a connection hose 21B are provided between the cleaner body 10B and the cleaner head 100B so that the suction force generated by the cleaner body 10B can be transmitted to the cleaner head 100B. A handle 30B may be provided between the connection pipe 20B and the connection hose 21B so that the user can hold it by hand.

The connection hose 21B is preferably formed of an elastic corrugated pipe, one end of which is connected to the cleaner body 100B and the other end of which may be connected to the handle 30B. The connection hose 21B allows the cleaner head 100B to move freely within a predetermined radius about the cleaner body 10B.

The connecting pipe 20B is connected to the cleaner body 100B at one end and the other end to the handle 30B so that the user can grab the handle 30B and move the cleaner head 100B to clean foreign substances on the floor. .

The cleaner head 100B is provided to suck foreign substances such as dust present on the floor while moving in contact with the floor.

The cleaner head 100B includes a head body 110B and a first brush case unit 200B and a second brush case unit 300B rotatably connected to the head body 110B.

The first brush case unit 200B may be rotatably connected to one side of the head body 110B, and the second brush case unit 300B may be rotatably connected to the other side of the head body 110B.

In the non-operation of the vacuum cleaner 1B, the user presses the connecting pipe 20B and the head body 110B fixed to the connecting pipe 20B in the downward direction.

At this time, the first brush case unit 200B and the second brush case unit 300B rotatably connected to the head body 110B may include a first brush case rotating arm 220B and a second brush case rotating arm ( By the rotation of the 320B can be rotated in the first direction (X) and the second direction (Y), respectively. The first brush case unit 200B and the second brush case unit 300B are spaced apart from each other.

The contact area for supporting the vacuum cleaner 1B on the floor is widened by the first brush case unit 200B and the second brush case unit 300B, which are spaced apart from each other, and a connection pipe (the center of the cleaner head 100B) Since the position of 20B is fixed and supported, the vacuum cleaner 1B can be self-standing.

As such, stable self-supporting of the vacuum cleaner 1B is possible without the need for another structure or a separate device, so that the user may improve the ease of use of the vacuum cleaner 1B.

In the above, specific embodiments have been illustrated and described.
