Hereinafter, the operation of the lifting device according to the rotation of the stick portion in a state where the stick portion is connected to the cleaning unit will be described.

FIG. 11 is a side view of the cleaning apparatus according to the first embodiment of the present invention, in which the wheels are in contact with the floor surface. FIG. 12 is a perspective view of the cleaning apparatus according to the embodiment of the present invention, Side view of the device.

6 and 11, the stick 20 may be disposed substantially perpendicular to the cleaning unit 10 while the stick 20 is connected to the cleaning unit 10.

In this case, when the stick unit 20 is connected to the cleaning unit 10 and the cleaning unit 10 is stored, interference of the stick unit 20 with objects around the cleaning unit 10 is minimized .

The wheels 111 and 121 are in contact with the bottom surface F by the suspension structures of the moving devices 110 and 120 in a state where the stick portion 20 is upright with respect to the cleaning unit 10 .

The projecting portion 184 of the connecting member 180 is positioned at the lower end of the second slot 176 of the movable portion 170 in a state where the stick portion 20 is upright with respect to the cleaning unit 10 .

The lifting portion 172 of the movable portion 170 and the extension pin 118 may be spaced apart from each other while the stick portion 20 is upright with respect to the cleaning unit 10.

When the connection member 180 rotates by the first angle, the protrusion 184 must also rotate about the axis 109a by the first angle.

When the protrusion 184 rotates, the locus of the protrusion 184 is arc-shaped. When the protrusion 184 moves in an arc shape, the height of the protrusion 184 varies. The stick portion 20 is positioned above the shaft 109a and the protrusion portion 184 is positioned below the shaft 109a so that the stick portion 20 is positioned in the clockwise direction When rotated, the height of the projection 184 is increased.

The protruding portion 184 is located at the lower end of the second slot 176 of the movable portion 170 so that the protruding portion 184 is rotated about the axis 109a, Should rise in the second slot 176. Since the second slot 176 is linear, the protrusion 184 moves the movable part 170 while the protrusion 184 is lifted along the second slot 176.

9 and 10, in a state where the extension pin 118 is seated on the upper surface of the lifting part 172, the stick part 20 is moved in one direction at an angle larger than the second angle The protrusion 184 moves along the first slot 174.

At this time, the shape of the first slot 174 may be the same as the shape of the locus of the protrusion 184.

Therefore, the moving force of the protrusion 184 is not transmitted to the moving part 170 in the process of moving the protrusion 184 along the first slot 174, so that the moving part 170 is stopped And the wheels 111 and 121 are maintained in an elevated state.

In addition, the user can freely rotate the stick portion 20 in one direction or another direction within the angular range of the first slot 174.

According to the present invention, since the wheels 111 and 121 can be separated from the bottom surface F by the lifting device when the stick 20 is rotated in a predetermined direction or more in one direction, There is an advantage that the user can move the cleaning unit with little force when moving the cleaning unit manually.

12, the wheels 111 and 121 are spaced apart from the floor F by the lifting device, and a plurality of auxiliary wheels 151, 152, 153, 154 are in contact with the bottom surface F. Therefore, the cleaning unit 10 can be moved by the plurality of auxiliary wheels 151, 152, 153, 154 without friction between the wheels 111, 121 and the floor F.
