In addition, as shown in FIG. 2, the lever part 130 is inserted such that the rotating part 131 is rotatable in the central recess 124. A second cylindrical protrusion 135 is formed at the center of the rotating part 131, and a pair of first and second sliding protrusions 126a and 126b are formed on the outer circumference of the second cylindrical protrusion 135 to correspond to the first inclined protrusions 126a and 126b (see FIG. 4). Two inclined protrusions 137a and 137b (see FIG. 2) are formed. Accordingly, when the handle 133 of the lever unit 130 is rotated in one direction or in the opposite direction, the second inclined protrusions 137a and 137b that rotate together with the lever unit 130 are the first inclined protrusions 126a and 126b. ) And the waste container 120 is raised or lowered by a height corresponding to the turning angle of the handle 133 in sliding contact.

On the other hand, the coupling unit 140, as shown in Figure 2, includes a coupling groove 141 formed in the receiving portion (12a) of the cleaner body 11, the coupling protrusion 145 is snap-coupled to the coupling groove 141. . In this case, the coupling protrusion 145 is preferably made of a synthetic resin having a predetermined elasticity to be elastically coupled to the coupling groove 141. In addition, the coupling groove 141 and the coupling protrusion 145 are both sides are in contact with each other uneven coupling. That is, the coupling groove 141, as shown in Figs. 3a and 3b, the recessed parts (143a, 143b) are formed along the vertical direction to both sides. When the coupling protrusion 145 snaps to the coupling groove 141, protrusions 146a and 146b are formed at the front edges of the coupling protrusion 145 so as to be inserted into the recesses 143a and 143b on both sides, respectively. The protrusions 146a and 146b are formed in the vertical direction so as to correspond to the recessed portions 143a and 143b, respectively. In addition, the protrusions 146a and 146b may be formed to be somewhat larger than the volumes of the recesses 143a and 143b to induce a firm coupling when coupled to the recesses 143a and 143b.

In addition, the coupling groove 141 and the coupling protrusion 145 is coupled to the upper end is maintained at the bottom of the cyclone unit 110 as a whole while maintaining the airtight when the waste container 120, as shown in Figure 7b, the coupling groove 141 When the engaging projection 145 is snap-coupled to, has a different height so that a predetermined clearance (G) is formed between the inner upper surface (143c) of the coupling groove 141 and the upper surface (146c) of the engaging projection 145. . That is, as shown in Figure 6, the height (H1) of the coupling groove 141 is formed larger than the height (H2) of the coupling protrusion 145, the reason for having such a gap (G), the coupling unit 140 When the waste container 120 is lifted in a state fixed to the receiving groove 12a, the waste container 120 is not tilted to the side fixed by the coupling unit 140 to the horizontal state by lifting the cyclone portion 110 Can be combined at the bottom to maintain confidentiality. Accordingly, the waste container 120 is naturally raised / lowered by the pivoting operation of the lever unit 130 in a state where the waste container 120 is stably fixed in the receiving portion 12a.
