The bagging mechanism is disposed within a body of the trash receptacle. A first fixed edge and a second fixed edge intersecting the first fixed edge are provided at tops of internal surfaces of the body of the trash receptacle. The bagging mechanism includes a first pressing bar, which is able to slide along the second fixed edge to gather the open end of the trash bag onto the first fixed edge, and a second pressing bar, which is able to slide along the first fixed edge to gather the open end of the trash bag onto the second fixed edge. The first pressing bar and the second pressing bar are further able to work together to gather the trash bag to the intersection of the first fixed edge and the second fixed edge. In the vicinity of the intersection, a heat fusing device is disposed for heat fusing and sealing the trash bag. The bagging mechanism further includes driving means for driving the first pressing bar and the second pressing bar to move. With this arrangement, the issue that conventional smart trash receptacles do not have an automatic bagging mechanism or are only capable of semi-automatic trash bagging, with insufficient bag sealing, insecure sealing and low loading capacity can be solved. ## Claims ### Claim 1 A bagging mechanism for a trash receptacle (1), the trash receptacle having a body, and a first fixed edge and a second fixed edge intersecting the first fixed edge provided at top portions of internal surfaces of the body, the bagging mechanism comprising: a first pressing bar (2), which is configured to slide along the first fixed edge to gather an open end of a trash bag onto the second fixed edge; a second pressing bar (3), which is configured to slide along the second fixed edge to gather the open end of the trash bag onto the first fixed edge, wherein the first pressing bar (2) and the second pressing bar (3) are further configured to work together to gather the trash bag to the intersection of the first fixed edge and the second fixed edge; a heat fusing device (4) disposed for heat fusing and sealing the trash bag gathered by the first pressing bar (2) and second pressing bar (3) and positioned at the intersection; and a driving device for driving the first pressing bar (2) and the second pressing bar (3) to move. ### Claim 2 (depends on 1) The bagging mechanism of claim 1, wherein a first fixed bar (5) and a second fixed bar (6) intersecting the first fixed bar (5) are fixedly arranged at the top portions of internal surfaces of the body of the trash receptacle (1), with a lateral edge of the first fixed bar (5) forming the first fixed edge, and a lateral edge of the second fixed bar (6) forming the second fixed edge. ### Claim 3 (depends on 2) The bagging mechanism of claim 2, wherein the body of the trash receptacle (1) comprises a receptacle section and a main cover section (8) residing on the receptacle section; and the first pressing bar (2), the second pressing bar (3), the first fixed bar (5), the second fixed bar (6), the driving device (9) and the heat fusing device (4) are all disposed within the main cover section (8). ### Claim 4 (depends on 3) The bagging mechanism of claim 3, wherein the second pressing bar (3) is disposed parallel to the first fixed bar (5) and the first pressing bar (2) is disposed parallel to the second fixed bar (6), guide devices are provided respectively between the first pressing bar (2) and the first fixed bar (5), between the first pressing bar (2) and the second pressing bar (3), between the second pressing bar (3) and the second fixed bar (6) and between the second pressing bar (3) and the first pressing bar (2), and under guidance of the guide devices, the first pressing bar (2) and the second pressing bar (3) are configured to gather the open end of the trash bag to the intersection of the first fixed edge and the second fixed edge. ### Claim 5 (depends on 4) The bagging mechanism of claim 4, wherein the first pressing bar (2) defines a guide slot (7), which extends axially with respect thereto, and through which one end of the second pressing bar (3) is inserted;
