The description and drawings are to be regarded as illustrative in nature and embodiments of the application will take their place in the art readily understood by those skilled in the art. The application is not limited by the illustrated embodiments but is capable of considerable variation and modification, consistent with the principles of the application.

[0055] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily all directed to the same embodiment, or to a single alternative embodiment. It is explicitly contemplated that embodiments described herein can be combined with each other.

[0056] In order to make the technical personnel in the art better understand the application scheme, the technical scheme in the embodiments of the application will be described clearly and completely below in conjunction with the drawings.

[0057] Referring to the drawings Figures 1 to 13 The application provides a garbage bag sealing device, which comprises a main body 1, a rotating ring 2, at least two rotating pieces 3, a driving mechanism 4 and a sealing mechanism 5.

[0058] The main body 1 is used to install the garbage bag 1000, and a garbage channel 10 is provided on the main body 1 for the garbage bag 1000 to pass through. Specifically, the main body 1 includes an outer shell 11 and an annular receiving member 12. The garbage channel 10 passes through the main body 11 and the receiving member 12. The garbage bag 1000 is a continuous cylindrical garbage bag 1000 and is folded and housed in the receiving member 12. The method of housing the garbage bag 1000 in the receiving member 12 is shown in the attached figure. Figure 4 As shown, specifically, the receiving component 12 has a receiving space 120, and the receiving space 120 has an opening 121 on the side facing the garbage channel 10. The garbage bag 1000 is folded and received in the receiving space 120 and passes through the opening 121 to cover the garbage channel 10. The lower part of the outer shell 11 is connected to the garbage bin, and the garbage channel 10 is connected to the garbage bin. The garbage bag 1000 is laid in the garbage channel 10 to be placed into the garbage bin. Garbage can fall from the garbage channel 10 into the garbage bin and be received in the garbage bag 1000. The outer shell 11 also has a mounting cavity 110, and at least a portion of the rotating ring 2, the rotating plate 3, and the drive mechanism 4 are installed in the mounting cavity 110.

[0059] It should be noted that, to facilitate the installation of components such as the rotating ring 2, the rotating plate 3, and the drive mechanism 4, in one embodiment, the outer shell 11 can be disassembled into a top shell 111 and a bottom plate 112, which together form an installation cavity 110. The receiving component 12 is detachably installed on the top shell 111 to facilitate the replacement of the receiving component 12 and the garbage bag 1000 stored inside it. After opening the bottom plate 112, the rotating ring 2, the rotating plate 3, and the drive mechanism 4 can be installed into the top shell 111, and the bottom shell can be fixed to the bottom of the top shell 111 with bolts to close the installation cavity 110. Specifically, a downwardly extending mounting boss 1101 is provided inside the top shell 111, the garbage channel 10 passes through the mounting boss 1101, and multiple downwardly extending limiting bosses 1102 are provided on the outer edge of the mounting boss 1101, with the limiting bosses 1101 abutting against the bottom plate 112. The rotating ring 2 is rotatably mounted between the mounting boss 1101 and the base plate 112. The limiting boss 1102 is used to prevent the rotating ring 2 from deviating in the horizontal direction, thereby fixing the position of the rotating ring 2.

[0060] Specifically, the rotating ring 2 is rotatably installed in the shell 11, and the rotating ring 2 is provided with a drop opening 20 through which the garbage bag 1000 passes, and the garbage channel 10 passes through the drop opening 20, that is, the rotating ring 2 is arranged around the garbage channel 10, and the rotating axis of the rotating ring 2 is located in the garbage channel 10. At least two rotating piece bodies 3 are distributed along the circumference of the rotating ring 2, and each of the at least two rotating piece bodies 3 includes a rotating end 31 and a working end 32. The rotating end 31 of each of the at least two rotating piece bodies 3 is located in the installation cavity 110 and is rotatably installed on the shell 11, and the working end 32 of each of the at least two rotating piece bodies 3 is slidably installed on the rotating ring 2. The driving mechanism 4 is installed in the installation cavity 110, and the driving mechanism 4 is drivingly connected with the rotating ring 2 to drive the rotating ring 2 to rotate around the garbage channel 10. The rotation of the rotating ring 2 can drive the working ends 32 of the at least two rotating piece bodies 3 to gather towards the center of the drop opening 20 and clamp the garbage bag 1000, or to move away from each other to open the drop opening 20.

[0061] The sealing mechanism 5 is installed on the working end 32 of at least one of the rotating piece bodies 3, and the sealing mechanism 5 is used for heating the garbage bag 1000, and preferably, the sealing mechanism 5 is distributed on each of the rotating piece bodies 3. In operation, the rotating ring 2 is first rotated to drive the rotating piece bodies 3 to gather towards the center of the drop opening 20 and clamp the garbage bag 1000, and the gathering process reduces the size of the bag opening of the garbage bag 1000. Then the sealing mechanism 5 starts to work and heats the bag opening of the garbage bag 1000, so that the bag opening of the garbage bag 1000 is melted to complete the sealing, and increasing the heating time of the sealing mechanism 5 can also realize the cutting of the garbage bag 1000. In addition, after the sealing mechanism 5 completes the sealing of the last garbage bag 1000, it also simultaneously seals the bottom of the next garbage bag 1000. After the sealing of the garbage bag is completed, the rotating ring 2 is reversely rotated to move the rotating piece bodies 3 away from each other to reopen the drop opening 20, and a new garbage bag 1000 is laid in the garbage channel 10 to wait for the next batch of garbage to drop.

[0062] Therefore, in the garbage bag sealing device, only the rotating ring needs to be driven to rotate forward or reverse by a certain angle, and the rotation of the rotating ring synchronously drives the plurality of rotating piece bodies to move, greatly shortening the working time. In addition, only the rotating ring needs to be driven to complete all the work, that is, only a single driving mechanism is needed, which can save costs.

[0063] Further, regarding the structure that the rotating ring 2 drives the rotating pieces 3 to move together, in the embodiment, the garbage bag sealing device further comprises at least two sliding shaft bases 6, the number of the sliding shaft bases 6 corresponds to the number of the rotating pieces 3. Taking two rotating pieces 3 as an example for description, that is, the sliding shaft bases 6 are two, each sliding shaft base 6 is correspondingly installed on a rotating piece 3 or the rotating ring 2, each sliding shaft base 6 is used for realizing the sliding connection between the rotating piece 3 and the rotating ring 2, and the sliding shaft base 6 and the rotating shaft center 311 of the rotating end 31 are deviated from each other, that is, the sliding shaft base 6 cannot be coaxially arranged with the rotating end 31.

[0064] For example, as shown in one embodiment of the garbage bag sealing device in FIG. 2, the rotating piece 3 is located above the rotating ring 2, the rotating end 31 extends upward and is inserted into the main body 1 to rotate, the sliding hole 7 is arranged on the rotating ring 2 and extends toward the falling opening 20, and the sliding shaft base 6 is arranged on the bottom surface of the rotating piece 3 and extends downward to be inserted into the sliding hole 7 and slide along the sliding hole 7. Figure 5 For example, as shown in one embodiment of the garbage bag sealing device in FIG. 2, the rotating piece 3 is located above the rotating ring 2, the rotating end 31 extends upward and is inserted into the main body 1 to rotate, the sliding hole 7 is arranged on the rotating ring 2 and extends toward the falling opening 20, and the sliding shaft base 6 is arranged on the bottom surface of the rotating piece 3 and extends downward to be inserted into the sliding hole 7 and slide along the sliding hole 7. 6 For example, as shown in one embodiment of the garbage bag sealing device in FIG. 2, the rotating piece 3 is located above the rotating ring 2, the rotating end 31 extends upward and is inserted into the main body 1 to rotate, the sliding hole 7 is arranged on the rotating ring 2 and extends toward the falling opening 20, and the sliding shaft base 6 is arranged on the bottom surface of the rotating piece 3 and extends downward to be inserted into the sliding hole 7 and slide along the sliding hole 7. For example, as shown in one embodiment of the garbage bag sealing device in FIG. 2, the rotating piece 3 is located above the rotating ring 2, the rotating end 31 extends upward and is inserted into the main body 1 to rotate, the sliding hole 7 is arranged on the rotating ring 2 and extends toward the falling opening 20, and the sliding shaft base 6 is arranged on the bottom surface of the rotating piece 3 and extends downward to be inserted into the sliding hole 7 and slide along the sliding hole 7.

[0065] For example, as shown in one embodiment of the garbage bag sealing device in FIG. 2, the rotating piece 3 is located above the rotating ring 2, the rotating end 31 extends upward and is inserted into the main body 1 to rotate, the sliding hole 7 is arranged on the rotating ring 2 and extends toward the falling opening 20, and the sliding shaft base 6 is arranged on the bottom surface of the rotating piece 3 and extends downward to be inserted into the sliding hole 7 and slide along the sliding hole 7. Figure 7 For example, as shown in one embodiment of the garbage bag sealing device in FIG. 2, the rotating piece 3 is located above the rotating ring 2, the rotating end 31 extends upward and is inserted into the main body 1 to rotate, the sliding hole 7 is arranged on the rotating ring 2 and extends toward the falling opening 20, and the sliding shaft base 6 is arranged on the bottom surface of the rotating piece 3 and extends downward to be inserted into the sliding hole 7 and slide along the sliding hole 7. For example, as shown in one embodiment of the garbage bag sealing device in FIG. 2, the rotating piece 3 is located above the rotating ring 2, the rotating end 31 extends upward and is inserted into the main body 1 to rotate, the sliding hole 7 is arranged on the rotating ring 2 and extends toward the falling opening 20, and the sliding shaft base 6 is arranged on the bottom surface of the rotating piece 3 and extends downward to be inserted into the sliding hole 7 and slide along the sliding hole 7.

[0066] For example, as shown in one embodiment of the garbage bag sealing device in FIG. 2, the rotating piece 3 is located above the rotating ring 2, the rotating end 31 extends upward and is inserted into the main body 1 to rotate, the sliding hole 7 is arranged on the rotating ring 2 and extends toward the falling opening 20, and the sliding shaft base 6 is arranged on the bottom surface of the rotating piece 3 and extends downward to be inserted into the sliding hole 7 and slide along the sliding hole 7. Figure 8In another embodiment shown, the rotating piece 3 is located above the rotating ring 2, the rotating end 31 extends upward and is inserted into the main body 1 for rotation, a torsion spring 33 is sleeved on the rotating end 31, so that the torsion spring 33 connects the rotating piece 3 and the shell 11; the sliding shaft table is arranged upwardly on the rotating ring 2, the sliding shaft table abuts against the outer wall of the rotating piece 3, and the sliding shaft table 6 can slide along the outer wall of the rotating piece 3. Specifically, when the rotating ring 2 rotates forward, the sliding shaft table presses the outer wall of the rotating piece 3 to swing the working end 32 of the rotating piece 3 to the center of the drop opening 20, and at the same time, the torsion spring 33 is elastically stored; when the rotating ring 2 rotates reversely, the elastic force of the torsion spring 33 drives the rotating piece 3 to reset to open the drop opening 20.

[0067] In other embodiments, the rotating piece can also be arranged below the rotating ring 2, and the rest of the design can refer to the above three embodiments.

[0068] Further, in the embodiment, the driving mechanism 4 includes a motor 41 and a driving gear 42, the motor 41 is fixedly installed in the installation cavity 110, and the driving gear 42 is installed on the output shaft of the motor 41. The shell 11 is provided with a limiting structure for the rotating ring 2, which is used to limit the position of the rotating ring 2, so that the rotating ring 2 can only rotate around the garbage channel 10. The rotating ring 2 is provided with a driven tooth structure 21 extending in the circumferential direction on the side thereof, and the driven tooth structure 21 is engaged with the driving gear 42, so as to drive the rotating ring 2 to rotate through the driving gear 42.

[0069] Further, the number of the rotating pieces 3 is even, and each two rotating pieces 3 constitute a set of sealing gates 300, and the two rotating pieces 3 included in each set of sealing gates 300 are distributed in central symmetry around the rotating ring 2, and a plurality of sets of sealing gates 300 are stacked in the vertical direction.

[0070] For example, as shown in the accompanying drawings Figure 5 In one embodiment shown, two rotating pieces 3 are installed on the rotating ring 2, that is, only one set of sealing gates 300 is provided.

[0071] For example, as shown in the accompanying drawings Figure 9 In another embodiment shown, four rotating pieces 3 are installed on the rotating ring 2, that is, two sets of sealing gates 300 are provided, and there is a 90° included angle between the two sets of sealing gates 300, and one set of sealing gates 300 is located above the other set of sealing gates 300.

[0072] Further, each set of sealing gates 300 has two working ends 32 and two rotating ends 31, the two working ends 32 are both bent towards the center of the drop opening 20, forming a shape similar to “C” or other hook-like shapes, which are mainly used to gather the garbage bag 1000 and reduce the length of the bag opening of the garbage bag 1000. Referring to the accompanying drawings Figure 10Both working ends 32 include a connecting section 321, an abutting section 322, and a guiding section 323 connected in sequence. Each connecting section 321 is connected to the corresponding rotating end 31, and the abutting sections 322 of the two working ends 32 can abut against each other. Furthermore, when the abutting sections 322 of the two working ends 32 abut against each other, the guiding section 323 of each working end 32 is staggered with the connecting section 321 of the other working end 32, forming the configuration shown in the attached figure. Figure 5 Or as shown in Figure 9. Both the guide section 323 and the connecting end are designed to be inclined, working together to guide the garbage bag 1000 towards the abutment section 322. A sealing mechanism 5 is installed on the abutment section 322 to achieve a heat-sealing of the garbage bag 1000.

[0073] Furthermore, the sealing mechanism 5 is installed on at least one set of sealing gates 300, specifically, the number of sealing mechanisms 5 is the same as the number of sets of sealing gates 300, that is, each set of sealing gates 300 is equipped with one sealing mechanism 5. See Appendix for details. Figures 11 to 13 The sealing mechanism 5 includes a heating element 51 and an abutment element 52. The heating element 51 is installed on the working end 32 of one of the rotating plates 3 of the sealing gate 300, and the abutment element 52 is installed on the working end 32 of the other rotating plate 3. The heating element 51 and the abutment element 52 abut against each other and together clamp the garbage bag 1000. After being heated, the heating element 51 heat-seales the clamped part of the garbage bag 1000. The abutment element 52 is mainly used to increase the contact pressure between the heating element 51 and the garbage bag 1000. It should be noted that a power supply and controller can be installed inside or outside the main body 1 to control the start and stop of the heating element 51 and the motor 41.

[0074] Furthermore, the heating element 51 includes a fixing strip 511 and a heating wire 512 wound around the fixing strip 511. The fixing strip 511 is embedded in the abutment section 322 of one of the rotating plates 3, and the abutment member 52 is embedded in the abutment section 322 of the other rotating plate 3. The two abutment sections 322 abut against each other through the heating wire 512 and the abutment member 52. It is necessary to open fitting grooves 3221 on both abutment sections 322, with each fitting groove 3221 opening towards the other abutment section 322. The fixing strip 511 and the abutment member 52 are respectively fitted into the two fitting grooves 3221.

[0075] Specifically, the rotating piece 3 is made of high-temperature resistant plastic material. The heating member 51 further comprises a first heat insulation layer 513 wrapping the fixing strip 511 and the heating wire 512. The fixing strip 511 is provided with a winding groove 5111 around the circumference thereof, and the heating wire 512 is wound in the winding groove 5111. The first heat insulation layer 513 is made of Teflon tape (heat-resistant material), and is wrapped on the fixing strip 511, and the heating wire 512 is exposed only on the side of the first heat insulation layer 513 facing the other rotating piece 3. The first heat insulation layer 513 is mainly used to prevent the heating wire 512 from melting the rotating piece 3.

[0076] In addition, the abutting member 52 comprises a soft base layer 521 and a second heat insulation layer 522 wrapping the soft base layer 521. The soft base layer 521 is made of rubber material, and the second heat insulation layer 522 is also Teflon tape. The heating wire 512 can abut against the second heat insulation layer 522 to jointly clamp the garbage bag 1000. The soft base layer 521 is used to provide soft contact for the heating wire 512 and the abutting member 52, so as to prevent damage to the heating wire 512. The second heat insulation layer 522 is used to prevent the heating wire 512 from melting the soft base layer 521.
