ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a waste bin structure, and more particularly to a waste bin structure that can be opened by a triggering action, and by a stepping action of a user's foot so that the waste bin structure has dual functions and effects.
DESCRIPTION OF THE RELATED PRIOR ART
A conventional waste bin is used for storing wastes or rubbish therein. However, the conventional waste bin is not provided with a cover or lid, so that the wastes are directly in contact with the air of the ambient environment. Therefore, when the wastes are organism that are derived from the kitchen, for example, the odor of the wastes will leak from the waste bin to the ambient environment, thereby causing uncomfortable sensation to the people. In addition, the conventional waste bin is not provided with a cover or lid, so that the wastes are exposed to the ambient environment, thereby decreasing the aesthetic appearance of the conventional waste bin.
A first conventional covered waste bin includes an upper cover formed with a protrusion so that the user can hold the protrusion for removing the upper cover. However, the user has to operate the upper cover manually, thereby causing inconvenience to the user.
A second conventional covered waste bin includes a single cover piece. However, its airtight effect is not sufficient, so that the odor of the wastes easily leaks from the waste bin to the ambient environment.
A third conventional covered waste bin includes a pedal having a bottom pivoted with a linking lever set, whereby the pedal can be stepped so that the linking lever set is driven to push an upper cover for removing the upper cover. The third conventional covered waste bin has a better airtight effect, however, it is not easy to clean the waste bin.
A fourth conventional covered waste bin includes a barrel lid having a trigger point which may be pressed so that the locking set mounted in the barrel lid can be locked or released, so as to close or open the upper cover. However, the operation of the barrel lid is not suitable for a large waste bin, so that the volume of the waste bin is limited.
SUMMARY OF THE INVENTION
The present invention has arisen to mitigate and/or obviate the disadvantage of the conventional waste bin.
The primary objective of the present invention is to provide a waste bin structure which can be opened by a triggering action, and by a stepping action of a user's foot so that the waste bin structure has dual functions and effects.
Another objective of the present invention is to provide a waste bin structure which can be opened by a triggering action, or by a stepping action of a user's foot, depending on the volume of wastes, by means of the pivotal connection of an inner cover and an outer cover of a barrel cover.
A further objective of the present invention is to provide a waste bin structure, wherein the gap between the inner barrel and the outer barrel can be covered by means of the pivotal mounting of the outer cover of the barrel cover, thereby preventing the wastes from falling into the gap between the inner barrel and the outer barrel.
A further objective of the present invention is to provide a waste bin structure which may be portable by mounting of a handle portion of the outer barrel.
A further objective of the present invention is to provide a waste bin structure which includes an inner barrel that can be removed to be cleaned. In addition, the inner barrel is provided with a hanging hook for hanging the inner barrel into the outer barrel without wobbling. Further, the hanging hook of the inner barrel may also function as a handle, so that the inner barrel is portable.
Thus, in accordance with the present invention, there is provided a waste bin structure comprising:
an inner barrel, an outer barrel, and a barrel lid, the inner barrel received in the outer barrel, a connecting portion mounted on a rear end of an inner rim of the outer barrel, the connecting portion having a top face integrally formed with a cover, the cover having a front end provided with two hanging shafts, the barrel lid having a distal end provided with two hanging ears each snapped on the hanging shaft of the cover so that the barrel lid covers a top edge of the outer barrel, the barrel lid provided with a locking portion that is opened and closed by triggering, so that the barrel lid can be opened by triggering action, the connecting portion of the outer barrel having a center defining a channel, a linking lever received in the channel and having a first end formed with a horizontal bent portion passing through a protruding ear of a bottom of a rear end of the barrel lid, and a second end passing through a front end of the outer barrel and pivoted with a pedal which may be stepped so that the linking lever pushes the lid cover to pivot upward;
the improvement comprising:
the lid cover including an inner cover and an outer cover, the inner cover placed in an inner rim of the outer cover, the locking portion of the lid cover mounted between the inner cover and the outer cover, the inner cover having a front end provided with a touch portion that may be pressed so as to pivot the inner cover to move upward independently, the top face of the connecting portion of the outer barrel having a front end defining a hanging recess, the inner barrel having a rear side having a top edge provided with a hanging hook portion secured in the hanging recess of the connecting portion of the outer barrel, the outer barrel having a back side provided with a hood, a plurality of screws each in turn extending through the hood, the outer barrel, and the connecting portion, so that the connecting portion is secured inside of a top portion of the outer barrel, and the hood is secured outside of the top portion of the outer barrel to form a handle portion of the outer barrel, such that the outer barrel is portable, and the lid cover of the waste bin structure can be opened by a triggering action, and by a stepping action of a foot.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
