Closed-type garbage can with outer bucket lifting

Abstract

A sealed trash can with an outer bucket that lifts up includes: a base with a foot pedal space in the middle, a gear pivotally mounted on both sides of the foot pedal space, a foot pedal disposed in the foot pedal space, and external tooth surfaces on both sides of the foot pedal that can mesh with the gears; an inner bucket disposed above the base; an outer bucket covering the inner bucket and the base; the outer bucket having at least one inlet opening opposite the bucket opening; and internal tooth surfaces on both sides of the inner wall of the outer bucket that can mesh with the gears. The external tooth surfaces of the foot pedal can drive the gears to rotate, and the gears synchronously drive the internal tooth surfaces, thereby raising the outer bucket to connect the inlet opening with the bucket opening, or lowering the outer bucket to disconnect the inlet opening from the bucket opening, thus creating a good sealed state, and also having the advantages of simple structure and easy operation.

Claims

1. A sealed trash can with an outer lifting mechanism, comprising: A base with a footrest space in the middle, and a gear pivotally mounted on both sides of the footrest space. A platform is formed on the upper surface of the base, and a groove is recessed on the surface of the platform. A footrest is located in the footrest space, and an external tooth surface is formed on both sides of the footrest, which meshes with the gear. An inner tub is located above the base, with an opening facing upwards. A plurality of bottom posts protrude from the bottom edge of the inner tub, and the inner tub is inserted into the groove via these bottom posts. A frame is attached to the inner tub, and a frame groove is recessed within the frame. A plurality of top posts protrude from the top edge of the inner tub, and the inner tub is inserted into the frame groove via these top posts. The inner tub is composed of a plurality of plates. The bottom post and the top post are symmetrically formed at one corner of the plate. The plate slides on the groove with the bottom post and slides on the frame groove, so that the plate is pressed towards the center of the inner barrel. An outer barrel covers the inner barrel and the base. The outer barrel has at least one avoidance opening at its lower edge relative to the foot pedal space and at least one insertion opening at its upper edge relative to the barrel opening. The outer barrel has an internal tooth surface on both sides of its inner wall, and the outer barrel meshes with the gear with the internal tooth surface. The external tooth surface of the foot pedal can drive the gear to rotate, and the gear synchronously drives the internal tooth surface, which can raise the outer barrel to make the insertion opening communicate with the barrel opening, or lower the outer barrel to make the insertion opening and the barrel opening disconnected.

2. The enclosed trash can with an outer bucket lift as described in claim 1, wherein the platform is supported by at least four legs, and the gear is disposed between two adjacent legs.

3. The airtight trash can with an outer lifting mechanism as described in claim 1, wherein the frame is made of an elastic material.

4. The sealed trash can with an outer bin that lifts as described in claim 1, wherein the base, the inner bin, and the outer bin are all formed in a quadrilateral, pentagonal, or hexagonal shape.

5. The enclosed trash can with an outer bin that lifts as described in claim 4, wherein the inlet of the outer bin is opened on each side, and the number of the plates is equal to the number of sides of a quadrilateral, pentagonal, or hexagonal shape.

6. The sealed trash can with an outer lifting mechanism as described in claim 5, wherein the number of the bottom posts and the top posts of the plate is two.

7. The sealed trash can with an outer bucket lifting mechanism as described in claim 5, wherein each of the plates has a groove and a protrusion parallel to the platform, and the plates are slidably disposed between the plates by the protrusion in the groove, so that the plates interlock to form a ring structure to limit the displacement direction of the plates.
