The following is a general description of the general operation of the cleaner.

First, when an operator applies power to the main body 300 using the power plug 350 and turns on the power switch, a motor (not shown) installed inside the main body 300 is In addition to being rotated at a high speed, a strong suction force is generated.

Then, when the wind speed control switch of the handle member 240, the outside air is sucked into the suction device 100 in proportion to the operation of the wind speed control switch, the outside introduced into the suction device 100 Air is introduced into the body 300 through the communication device 200.

Thereafter, according to the operator's choice, the cleaning work can be completed by turning off the power plug 350, and the cleaning work is performed while moving the main body 300 to another cleaning part using the carrying handle 340. You can continue to run.

However, the conventional suction apparatus 100 as described above has a problem in that the suction efficiency is lowered during vacuuming so that efficient cleaning cannot be performed.

That is, when vacuuming, the user grabs the handle member 240 and pushes and pulls the suction device 100 in the direction of arrow K shown in FIG. 3 to perform the cleaning. When pushing in the left direction (the user's front direction) of the arrow K shown, since the rear wheel 150 and the front wheel 160 are all in close contact with the ground, efficient cleaning can be performed without deteriorating the suction efficiency of the cleaner. .

However, when the user pulls the suction device 100 in the right direction (rear direction of the user) of the arrow K shown in the drawing, the main body 300 is also shown in a dotted line while the suction device 100 is lifted in the arrow H direction shown. As the L is heard from the ground to a predetermined height bar, the suction efficiency of the suction device 100 is lowered by a spaced interval between the ground and the rear wheel 150, thereby causing a problem that the cleaning efficiency is lowered there was.

In addition, even if the communication device 200 is articulated by the circular coupling portion 211 of the connector 210 is not articulated to be parallel to the ground, the floor of the furniture such as a bed using a conventional suction device 100 When cleaning the surface or deep corners, there was a problem that the front portion of the suction device 100 is lifted and the suction efficiency is lowered and the cleaning efficiency is also lowered.

The present invention has been devised to solve all of the above problems, and even if the rear wheel of the suction device is separated from the ground during vacuum cleaning, the suction efficiency of the suction device is prevented from being lowered so that efficient cleaning can be performed. Its purpose is to provide a vacuum cleaner.

In addition, the communication device is made of a plurality of joints to be in a horizontal state with the ground, even when cleaning the floor or deep corners of the furniture, such as a bed to prevent the lifting of the front portion of the suction device cleaning efficiency is It is an object of the present invention to provide a vacuum cleaner that can prevent the degradation.

The present invention for achieving the above object, in the vacuum cleaner consisting of the suction device and the communication device and the main body, both ends of the suction passage member and the lower cover so that the lower cover of the suction device is elastically movable in the vertical direction. It is installed by a plurality of springs fixed to the hinge coupled to the lower portion of the upper cover to enable forward and rearward rotation, characterized in that the communication device is made of a plurality of joints movable to maintain a level with the ground.
