Detailed implementation manners

[0030] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific implementation manners of the present utility model with reference to the drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0031] The following will further describe the present utility model with reference to the drawings and embodiments.

[0032] See Figures 1 - 13, The garbage bag sealing and cutting structure of this trash can includes a trash can lid 1, on which there is a lid opening 2. A heat-sealing component A for sealing the garbage bag and a cutting component B for cutting the garbage bag are movably arranged at the lid opening 2.

[0033] In this embodiment, the heat-sealing component A and the cutting component B are respectively used to seal and cut the garbage bag, making the division of labor for the sealing function and the cutting function of the garbage bag more detailed and clear. Thus, it effectively avoids the problems caused by a single hot-melt device for thermoplastic sealing and thermal fusing of the garbage bag, such as high power of the hot-melt device, high usage cost, and potential safety hazards. In addition, since the sealing function and the cutting function are separated, it is convenient to judge functional failures, thereby improving the convenience of daily maintenance of the product.

[0034] As a preferred solution of this embodiment, it may also have the following additional technical features:

[0035] The trash can lid 1 is provided with a common driving component C or different driving components corresponding to the heat-sealing component A and the cutting component B. The heat-sealing component A and the cutting component B are simultaneously moved through the common driving component C, or the heat-sealing component A and the cutting component B are separately moved or simultaneously moved through different driving components.

[0036] In this embodiment, when the common driving component C is set, the common driving component C is used to drive the heat-sealing component A and the cutting component B to move simultaneously, and its structure is simple. When different driving components are set, the different driving components are used to drive the heat-sealing component A and the cutting component B to move separately or simultaneously, which can ensure the normal movement of the heat-sealing component A and the cutting component B.

[0037] At least one heat-sealing component A is provided, and at least one cutting component B is provided. At least one heat-sealing component A and at least one cutting component B are arranged vertically and / or horizontally.

[0038] In this embodiment, the heat-sealing component A and the cutting component B are arranged on the same side, that is, the heat-sealing component A and the cutting component B are arranged on the same side of the lid opening 2. By doing so, not only the space occupied by the heat-sealing component A and the cutting component B on the trash can lid 1 is reduced, but also the heat-sealing component A and the cutting component B can complete the sealing and cutting of the garbage bag opening on the same side of the lid opening 2, ensuring the smooth progress of sealing and cutting.

[0039] The heat-sealing component A is hinged and opened / closed or slid and opened / closed along the opening direction of the lid opening 2, and the cutting component B is hinged and opened / closed or slid and opened / closed along the opening direction of the lid opening 2.

[0040] In this embodiment, the heat-sealing component A and the cutting component B can be hinged to move away from or close to each other to respectively achieve sealing and cutting, or the heat-sealing component A and the cutting component B can be slid to move away from or close to each other to respectively achieve sealing and cutting.

[0041] In addition, the heat-sealing component A and the cutting component B can be hinged or slid open and closed at any angle relative to the cover 2, so as to meet the sealing and cutting requirements at different positions of the garbage bag.

[0042] Specifically, an assembly groove 3 is provided on the trash can cover 1, two heat-sealing components A are provided and arranged up and down with respect to each other, and the two heat-sealing components A are movably provided on the assembly groove 3, one cutting component B is provided and is located between the two heat-sealing components A, and the cutting component B is movably provided on the assembly groove 3.

[0043] In this embodiment, the two heat-sealing components A are respectively located at the upper and lower positions of the cutting component B, and the three constitute a three-layer clamp. When working, the two heat-sealing components A respectively seal the upper and lower positions of the garbage bag and clamp the garbage bag in place at the same time. When working, the cutting component B cuts off the middle position of the garbage bag after the upper and lower sealing. Since the two heat-sealing components A can seal the upper and lower positions of the garbage bag and clamp it in place, it is convenient to cut off the cutting component B. At the same time, the old garbage bag after cutting can be sealed at the bottom and top, and the bottom of the new garbage bag after replacement can also be sealed.

[0044] The two heat-sealing components A each include a first sealing block 4 and a second sealing block 5. A heat-sealing member 6 is provided on the first sealing block 4 and / or the second sealing block 5. The first sealing block 4 and the second sealing block 5 rotate on the assembly groove 3 through different rotation points or the same rotation point, and are linked to each other or rotate independently when rotating. The cutting component B includes a first cutting piece 7 and a second cutting piece 8. The first cutting piece 7 and the second cutting piece 8 rotate on the assembly groove 3 through different rotation points or the same rotation point, and are linked to each other or rotate independently when rotating.

[0045] That is, a rotating part is respectively provided between the first sealing block 4 and the second sealing block 5, and between the first cutting piece 7 and the second cutting piece 8, and they are respectively rotated on the trash can cover 1 through the rotating parts; or, the same rotating part is provided between the first sealing block 4 and the second sealing block 5, and between the first cutting piece 7 and the second cutting piece 8, and they are rotated on the trash can cover 1 through the same rotating part (similar to the hinge method), and at the same time, the first sealing block 4 and the second sealing block 5, and the first cutting piece 7 and the second cutting piece 8 can be rotated in linkage (that is, when one of them rotates, it can drive the other The two sealing blocks 4 can be rotated simultaneously with each other), or they can be rotated separately (that is, they do not interfere with each other when rotating). In addition, the heat sealing member 6 can be set separately on the first sealing block 4, or set separately on the second sealing block 5, or set simultaneously on the first sealing block 4 and the second sealing block 5. In order to ensure that the garbage bag can be sealed while simplifying the structure, the present embodiment preferably provides a heat sealing member 6 on the inner side of the first sealing block 4. The heat sealing member 6 can be a heating wire, a heating sheet, etc. When the first sealing block 4 is close to the second sealing block 5, the heat sealing member 6 is used to seal the garbage bag.

[0046] The first sealing block 4 and the first cutting piece 7, and / or the second sealing block 5 and the second cutting piece 8 are rotated on the assembly groove 3 through different rotation points or the same rotation point, and the first sealing block 4 and the second sealing block 5, and the first cutting piece 7 and the second cutting piece 8 are respectively directly connected by transmission or connected by transmission through an intermediate transmission member.

[0047] Furthermore, a first rotating shaft 9 is arranged between one end of the first sealing block 4 and one end of the first cutting piece 7, and the two are rotatably arranged on the assembly groove 3 through the first rotating shaft 9, a second rotating shaft 10 is arranged between one end of the second sealing block 5 and one end of the second cutting piece 8, and the two are rotatably arranged on the assembly groove 3 through the second rotating shaft 10, and the first sealing block 4 and the second sealing block 5, and / or the first cutting piece 7 and the second cutting piece 8 are mutually meshed or frictionally transmitted.

[0048] In this embodiment, the first rotating shaft 9 sequentially passes through the first sealing block 4 of the first heat sealing component A, the first cutting piece 7, and the first sealing block 4 of the second heat sealing component A, and is finally positioned on the assembly groove 3. The second rotating shaft 10 sequentially passes through the second sealing block 5 of the first heat sealing component A, the second cutting piece 8, and the second sealing block 5 of the second heat sealing component A, and is finally positioned on the assembly groove 3.

[0049] In addition, a first tooth part 22 is arranged on the periphery of the rotating end of the first sealing press block 4, and a second tooth part 23 is arranged on the periphery of the rotating end of the second sealing press block 5. The first tooth part 22 and the second tooth part 23 are meshed and driven with each other to realize the transmission between the first sealing press block 4 and the second sealing press block 5. The upper and lower positions of the rotating end of the first cutting piece 7 respectively rely on the first sealing press block 4 of the first and second heat-sealing assemblies A, and the upper and lower positions of the rotating end of the second cutting piece 8 respectively rely on the second sealing press block 5 of the first and second heat-sealing assemblies A, so that when the first sealing press block 4 and the second sealing press block 5 rotate, the first cutting piece 7 and the second cutting piece 8 are simultaneously driven to rotate through friction force.

[0050] The assembly groove 3 is located on one side of the cover opening 2, and a common driving assembly C is arranged thereon. The common driving assembly C is directly connected or connected through an intermediate member 11 to the first sealing press block 4, the second sealing press block 5, the first cutting piece 7, or the second cutting piece 8.

[0051] In this embodiment, the first sealing press block 4, the second sealing press block 5, the first cutting piece 7, and the second cutting piece 8 are all linearly extended, and they can rotate and open and close on one side of the cover opening 2. When the first sealing press block 4, the second sealing press block 5, the first cutting piece 7, and the second cutting piece 8 are opened, they are all located in the assembly groove 3 and will not block the cover opening 2. When the first sealing press block 4, the second sealing press block 5, the first cutting piece 7, and the second cutting piece 8 are closed, their outer ends are all located outside the assembly groove 3, and respectively seal and cut off the garbage bags on the cover opening 2.

[0052] The common driving assembly C includes an intermediate member 11, a reduction drive gear pair 12, a gear pair support 13, and a driving motor 14. A gear pair cavity 15 is arranged on the gear pair support 13, and the reduction drive gear pair 12 is rotatably arranged in the gear pair cavity 15. The gear pair support 13 is further provided with a gear pair cover plate 16, a gear pair support side opening 17, and a gear pair support convex hole 18. The gear pair cover plate 16 covers the gear pair cavity 15 and shields the reduction drive gear pair 12.

The driving motor 14 is fixedly arranged at the bottom of the gear pair support 13, and its driving end is drivingly connected with a motor driving gear 20. The motor driving gear 20 extends into the gear pair support convex hole 18 and is meshed and driven with the reduction drive gear pair 12 through the convex hole opening 19.
