(210) is formed so as to be inclined to slide the cigarette into the cigarette inlet 211, the cigarette inlet 211 is formed in the longitudinal direction of the roller 230 so that the cigarette is introduced in parallel with the roller 230 It is preferable that the width is formed to be slightly wider than the thickness of the cigarette.When the cigarette butts are thrown to the cigarette input portion 210, they slide naturally and are aligned in a direction parallel to the roller 230 to pass through the cigarette input hole 211. To fall between the pair of rollers (230).

A pair of rotatable rollers 230 are installed side by side under the cigarette inlet 211. The roller 230 is installed to be rotatable by a fixing part formed inside the lid 200, and cigarette butts dropped between the rollers 230 are compressed and extinguished by the rotation of the rollers 230. The roller 230 is preferably made of metal so as not to be deformed or burned by the heat of the cigarette butts. The interval between the rollers 230 is preferably narrow enough to completely extinguish the cigarette butt in a short time by the rotation of the roller 230.

In order to drive the roller 230 to rotate, a pair of pinion gears 240 are installed on the rotation shaft 232 of the roller 230, and a pair of racks that move in engagement with the pinion gear 240. The push rod 340 is formed along the side of the gear 341 is provided.

However, the pressing ball 343 has a narrow compression part is coupled to the pressing bar 344 at a predetermined position of the upper pressing rod 340 of the pressing ball (343). The presser 344 is manufactured by combining three, four or more rods, and any one portion thereof is fixedly coupled to the push rod 340. The presser 344 is preferably manufactured to press the waste in the trash evenly, the presser 344 shown in Figure 3 is a preferred example.

The drip tray 220 is provided under the roller 230 of the eco-friendly waste bin according to the present invention so that rainwater introduced through the cigarette inlet 210 is not introduced into the waste bin. When it rains, rainwater is introduced through the cigarette inlet 211. If it is left, water penetrates into the trash and easily rots the contents, causing odor. In order to prevent this, the drip tray 220 is installed below the roller 230.

The drip tray 220 is fixed to the inner upper surface of the lid 200 by a pair of drip tray fixing part 221. At this time, it is preferable that the rotating shaft 232 of the roller 230 is coupled to the drip tray fixing part 221 so as to be rotatable. The introduced rainwater falls on the drip tray 220 as a drop from the lower portion of the roller 230 on the outer surface of the roller 230 so that water does not flow into the body 100 of the trash can. In order to allow the water flowing along the outer surface of the roller 230 to fall more efficiently into the drip tray 220, a comb-shaped groove 231 is formed on the outer surface of the roller 230.

Rainwater collected in the drip tray 220 should be discharged to the outside of the trash can, for this purpose, the size of the trash can lid 200 is made larger than the upper portion of the body 100, the drain gap between the body 100 and the lid 200 ( 20) is formed. At this time, the end of the drip tray 220 is formed to the upper portion of the drain gap 20, so that the water flowing in the drip tray 220 is discharged through the drain gap 20. As a result, the rainwater introduced through the cigarette inlet 211 is collected in the drip tray 220 along the outer surface of the roller 230, and is discharged to the outside of the trash bin through the drain gap 20 along the drip tray 220.

One or more garbage inlets are formed in the lid 200 of the eco-friendly waste bin according to the present invention. The upper door 251 is hinged 253 to the inner surface of the 200 and the lower door 252 is hinged 254 to the upper door 251. In this case, the springs 255 and 256 are coupled between the inner surface of the upper door 251 and the lid 200, and the upper door 251 and the lower door 252, respectively, to the springs 255 and 256. To keep it closed. When a force is applied to inject waste, the door is opened and restored to a closed state by a spring when no force is applied, which is the same as a conventional waste bin inlet door.

However, as shown in FIGS. 6 and 7, the door 250 of the present invention is divided into upper and lower doors 251 and 252, unlike the conventional door, so that the upper door 251 and the lower door 252 are relatively. When the longitudinal force is applied to the door 250 by being rotatable, the upper and lower doors 252 are bent to form an angle by relatively rotating. By installing the door 250 in two stages with the upper and lower doors 251 and 252, it is possible to prevent the hand from being injured by the hand between the door and the inlet in the process of removing the hand after the waste.

In this case, a leakage preventing wall formed to form an inclined surface 313 along edges of the upper door 251 and the lower door 252 is formed. The leakage preventing wall prevents rainwater from penetrating between the door 250 and the inlet and entering the inside of the trash can. An end of the lower door 252 is positioned above the drain gap 20 formed between the lid 200 and the body 100. This is the same principle that the water is discharged to the outside of the bin through the drain gap 20 through the drip tray 220.

The push switch 300 is coupled to the upper end of the push rod 340 of the environment-friendly waste bin according to the present invention. As shown in FIGS. 4 and 5, the push switch 300 includes a switch body 310, a first insert 320, and a second insert 330. An accommodating part 311 is formed in the switch body 310 to accommodate the first insert 320, and a first spring 312 is installed below the accommodating part 311. Inside the switch body 310, the spring inserting groove 323 of the first insert 320 when the first insert 320 and the second insert 330 is pressed by a strong force or more than a predetermined force The locking protrusion 333 is released, and the second insert 330 is pushed up by the second spring, so that the display head 331 of the second insert 330 is moved by the first insert 320. The locking release inclined surface 313 is formed to be exposed to the outside.

The first spring 312 preferably uses a spring having a large spring coefficient so that the length of the first spring 312 is not large enough to be deformed with respect to the force applied by the first insert 320.

The first insert 320 accommodated in the switch body 310 is provided with an accommodating portion 322 in which the second insert 330 is accommodated, and the switch body 310 is disposed below the accommodating portion 322. The pressing rod 340 is coupled to the pressing rod 340 and the coupling bolt 324 is fixed, the spring engaging groove 323 is formed on the side.

The second insert 330 is accommodated inside the first insert 320 when the push switch 300 is not pressurized by a predetermined force or more, and the first insert (if the press switch 300 is pressurized by a predetermined force or more). A display head 331 exposed to the outside of the 320, a locking spring 332 fixed to an inner upper end of the display head 331, opened or contracted according to a pressurized state, and a locking protrusion 333 formed at an end thereof; It is configured to include a second spring accommodated in the lower portion. When the display head 331 is full of garbage in the waste bin, pressing the push switch 300, a predetermined force or more acts to operate the switch to protrude out of the first insert 320 to fill the inside of the waste bin. It serves to inform the In order to improve visibility, the surface of the display head 331 may be painted with a color that easily jumps on the eyes such as red and yellow.

The locking spring 332 may be designed in various forms, but is preferably an elastic body having a shape of “s” as shown in FIGS. 4 and 5, and may be manufactured by deforming an excellent elastic metal wire material. When no force is applied, it is unfolded from side to side as shown in FIG. 4, and when it is received inside and receives a force as shown in FIG. 5, it is deformed to store elastic energy. Both ends of the locking spring 332 is formed with a locking projection 333 is preferably formed in a round shape so that locking and release can occur easily.

A second spring is received at the lower end of the second insert 330. The second spring is compressed in the state in which the second insert 330 is completely inserted to maintain the force applied to the second insert 330 in the upward direction. At this time, when the locking protrusion 333 is released from the spring locking groove 323, the second insert 330 is pushed up so that the display head 331 is exposed to the outside of the first insert 320. Unlike the first spring 312, the second spring preferably uses a spring having a large deformation and a low spring coefficient.

To explain the operation principle of the push switch 300, first, when the inside of the waste bin is not full of garbage, a force is applied to the push switch 300 so that the push bar 340 moves downward, but the push ball 343 Since the force is not applied to the presser 344 and the first spring 312 accommodated in the switch body 310 does not cause deformation, the locking spring is caught in the spring locking groove 323 of the first inserting body 320. (332) does not touch the release slope 313 to maintain the original state. However, when the garbage is filled in the inside of the waste bin, when the force is applied to the push switch 300, the force is applied to the push ball 343 and the press bar 344 coupled to the lower end of the push rod 340, and thus the first insert ( Deformation occurs in the first spring 312 installed between the 320 and the switch body 310, the locking projection 333 protruding by the spring locking groove 323 of the first inserting body 320 is the release slope ( The latch is released from the spring catching groove 323 by 313 and the second insert 330 is pushed upward by the second spring so that the display head 331 is exposed to the outside.

The pedestal 110 is coupled to the bottom of the body 100 of the eco-friendly waste bin according to the present invention so that the body 100 is spaced apart from the floor by a predetermined or more, and a plurality of drain holes may be formed on the bottom of the body 100. This is to allow the water introduced with the waste to be discharged inside the bin. However, this may be contaminated with the outside of the trash can, so it is preferable to use the trash can installed in the place where the drain is provided.

As described above, the environmentally friendly waste bin is only one embodiment of the present invention, and the scope of the present invention is not to be interpreted limited by the preferred embodiment described above.
