[0055] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute a separate or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0056] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0057] See attached Figures 1 to 13 The present invention provides a garbage bag sealing device, which includes a main body 1, a rotating ring 2, at least two rotating plates 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 a shell 11 and an annular receiving part 12. The garbage channel 10 passes through the main body 11 and the receiving part 12. The garbage bag 1000 is specifically a continuous cylindrical garbage bag 1000 and is folded and received in the receiving part 12. The garbage bag 1000 is received in the receiving part 12 in the manner shown in the attached figure. Figure 4 As shown, the receiving member 12 is provided with a receiving space 120. The receiving space 120 has an opening 121 on one side facing the trash chute 10. A folded trash bag 1000 is stored in the receiving space 120 and passes through the opening 121, shielding the trash chute 10. The housing 11 is connected to the trash can below, with the trash chute 10 connected to the trash can. The trash bag 1000 is placed in the trash chute 10 for placement into the trash can. Trash can fall from the trash chute 10 into the trash can and be collected in the trash bag 1000. The housing 11 also has a mounting cavity 110, in which at least a portion of the rotating ring 2, rotating plate 3, and drive mechanism 4 are mounted.

[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 housing 11 can be split into a top shell 111 and a bottom plate 112, which together enclose a mounting cavity 110. The receiving member 12 is detachably mounted on the top shell 111 to facilitate replacement of the receiving member 12 and the garbage bag 1000 stored therein. 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. The bottom shell is then fixed to the bottom of the top shell 111 with bolts to close the mounting cavity 110. Specifically, a downwardly extending mounting boss 1101 is provided within the top shell 111, and the garbage chute 10 is provided through the mounting boss 1101. A plurality of downwardly extending limiting bosses 1102 are then provided on the outer edge of the mounting boss 1101, and the limiting bosses 1101 abut against the bottom plate 112. The rotating ring 2 is rotatably mounted between the mounting boss 1101 and the bottom plate 112 , and 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 mounted within the housing 11. A drop-out opening 20 is defined on the rotating ring 2 for the garbage bag 1000 to pass through. The garbage chute 10 passes through this drop-out opening 20. In other words, the rotating ring 2 is disposed around the garbage chute 10, and the rotation axis of the rotating ring 2 is located within the garbage chute 10. At least two rotating blades 3 are distributed along the circumference of the rotating ring 2. Each of the at least two rotating blades 3 includes a rotating end 31 and a working end 32. The rotating ends 31 of the at least two rotating blades 3 are located within the mounting cavity 110 and are rotatably mounted on the housing 11, while the working ends 32 of the at least two rotating blades 3 are slidably mounted on the rotating ring 2. A driving mechanism 4 is mounted within the mounting cavity 110 and is drivingly connected to the rotating ring 2 to drive the rotating ring 2 to rotate around the garbage chute 10. The rotation of the rotating ring 2 can drive the working ends 32 of at least two rotating plates 3 to gather toward the center of the drop opening 20 and clamp the garbage bag 1000, or drive the working ends 32 of at least two rotating plates 3 away from each other to open the drop opening 20.

[0061] A sealing mechanism 5 is mounted on the working end 32 of at least one rotating blade 3. The sealing mechanism 5 is used to heat the garbage bag 1000. Preferably, each rotating blade 3 is provided with a sealing mechanism 5. During operation, the garbage bag sealing device first rotates the rotating ring 2, driving the rotating blades 3 to converge toward the center of the drop opening 20 and clamp the garbage bag 1000. This convergence reduces the size of the opening of the garbage bag 1000. The sealing mechanism 5 then begins to heat the opening of the garbage bag 1000, melting it and completing the seal. Increasing the heating time of the sealing mechanism 5 also allows for the garbage bag 1000 to be cut. Furthermore, after the sealing mechanism 5 seals the previous garbage bag 1000, it also simultaneously seals the bottom of the next garbage bag 1000. After the garbage bag is sealed, the rotating ring 2 rotates in the opposite direction and moves the rotating plates 3 away from each other, reopening the drop opening 20, and a new garbage bag 1000 is laid in the garbage channel 10, waiting for the next batch of garbage to fall.

[0062] Therefore, in this garbage bag sealing device, only the rotating ring needs to be driven to rotate forward or reverse a certain angle. The rotation of the rotating ring synchronously drives the multiple rotating plates to move together, significantly shortening the working time. In addition, only the rotating ring needs to be driven to complete the entire operation, that is, only a single drive mechanism is required, which can save costs.

[0063] Furthermore, regarding the structure by which the rotating ring 2 drives the rotating blades 3 to move together, in this embodiment, the garbage bag sealing device further includes at least two sliding axle blocks 6, the number of which corresponds to the number of rotating blades 3. Taking two rotating blades 3 as an example, there are two sliding axle blocks 6, each mounted on a corresponding rotating blade 3 or on the rotating ring 2. Each sliding axle block 6 is used to achieve a sliding connection between a rotating blade 3 and the rotating ring 2, and the sliding axle blocks 6 and the rotating end 31 are offset from each other in the rotation axis 311, that is, the sliding axle blocks 6 cannot be coaxial with the rotating end 31.

[0064] For example, Figure 5 and 6 In one embodiment shown, the rotating sheet 3 is located above the rotating ring 2, and the rotating end 31 extends upward and is inserted into the main body 1 for rotation; a sliding hole 7 is provided on the rotating ring 2, and the sliding hole 7 extends in length toward the drop opening 20. The rotating shaft platform is installed on the bottom surface of the rotating sheet 3 and extends downward to be inserted into the sliding hole 7 and can slide along the sliding hole 7. Specifically, in the initial state, the two rotating sheets 3 are away from each other and the drop opening 20 is in an open state, and the rotating shaft block is at the end of the sliding hole 7 away from the drop opening 20. When the rotating ring 2 rotates forward, the rotating shaft block is driven to move forward to drive the rotating sheet 3 to swing forward and complete the gathering. Since the relative positions of the rotating shaft block and the rotating ring 2 change, the rotating shaft block will slide along the sliding hole 7 to the end close to the drop opening 20; when the rotating ring 2 rotates reversely, the rotating shaft block is driven to move reversely to drive the rotating sheet 3 to swing reversely and open the drop opening 20. Similarly, since the relative positions of the rotating shaft block and the rotating ring 2 change, the rotating shaft block will return to the initial position along the sliding hole 7.

[0065] For example, Figure 7 In another embodiment shown, a rotating plate 3 is positioned above the rotating ring 2, with a rotating end 31 extending upward and inserted into the main body 1 for rotation. A rotating shaft block is disposed on the rotating ring 2, extending upward. A sliding hole 7 is defined at the working end 32 of the rotating plate 3. The sliding hole 7 extends in the direction in which the working end 32 is disposed. A sliding shaft block 6 is inserted into and can slide along the sliding hole 7. This embodiment differs from the previous one in that the positions of the sliding shaft block 6 and the sliding hole 7 are reversed.

[0066] For example, Figure 8In another embodiment shown, the rotating disc 3 is positioned above the rotating ring 2, with a rotating end 31 extending upward and inserted into the main body 1 for rotation. A torsion spring 33 is mounted on the rotating end 31, connecting the rotating disc 3 to the housing 11. A rotating shaft block is disposed upwardly on the rotating ring 2, resting against the outer wall of the rotating disc 3. The sliding shaft block 6 can slide along the outer wall of the rotating disc 3. Specifically, when the rotating ring 2 rotates in the forward direction, the rotating shaft block applies pressure to the outer wall of the rotating disc 3, causing the working end 32 of the rotating disc 3 to swing toward the center of the drop opening 20, while simultaneously causing the torsion spring 33 to elastically store energy. When the rotating ring 2 rotates in the reverse direction, the elastic force of the torsion spring 33 drives the rotating disc 3 back to its original position, thereby opening 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] Furthermore, in this embodiment, the drive mechanism 4 includes a motor 41 and a drive gear 42. The motor 41 is fixedly mounted within the mounting cavity 110, and the drive gear 42 is mounted on the output shaft of the motor 41. A retaining structure for the rotating ring 2 is provided within the housing 11, restricting its position so that it can only rotate about the trash chute 10. A circumferentially extending driven tooth structure 21 is provided around the rotating ring 2. The driven tooth structure 21 meshes with the drive gear 42, thereby driving the rotating ring 2 to rotate.

[0069] Furthermore, the number of rotating sheets 3 is an even number, and every two rotating sheets 3 constitute a group of sealing gates 300. The two rotating sheets 3 included in each group of sealing gates 300 are distributed symmetrically around the rotating ring 2, and multiple groups of sealing gates 300 are staggered and stacked in the vertical direction.

[0070] For example, Figure 5 In the embodiment shown, two rotating plates 3 are mounted on the rotating ring 2 , that is, there is only one set of sealing gates 300 .

[0071] For example, Figure 9 In another embodiment shown, four rotating plates 3 are mounted on the rotating ring 2 , that is, there are two sets of sealing gates 300 , with a 90° 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] Furthermore, each set of the sealing gates 300 has two working ends 32 and two rotating ends 31. The two working ends 32 are bent toward the center of the drop opening 20 to form a shape similar to a "C" or other hook-like shape, which is mainly used to gather the garbage bags 1000 and reduce the length of the bag opening of the garbage bags 1000. Figure 10The two working ends 32 each 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 each other. 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 to form a vertical staggered arrangement as shown in the attached figure. Figure 5 Or the state shown in 9. Among them, the guide section 323 and the connecting end are both inclined designs, which are used together to guide the garbage bag 1000 to gather at the abutting section 322. The sealing mechanism 5 is provided on the abutting section 322 to achieve hot melt sealing of the garbage bag 1000.

[0073] Furthermore, the sealing mechanism 5 is installed on at least one group of sealing gates 300. Specifically, the number of sealing mechanisms 5 is the same as the number of groups of sealing gates 300, that is, each group of sealing gates 300 is installed with a sealing mechanism 5. Figures 11 to 13 The sealing mechanism 5 includes a heating element 51 and an abutting element 52. The heating element 51 is mounted on the working end 32 of one rotating plate 3 of the sealing gate 300, and the abutting element 52 is mounted on the working end 32 of the other rotating plate 3. The heating element 51 can abut against the abutting element 52 and together clamp the garbage bag 1000. After heating, the heating element 51 heats the clamped portion of the garbage bag 1000 to perform a heat-melt seal. The abutting element 52 is primarily 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 provided inside or outside the main body 1 to control the activation and deactivation of the heating element 51 and the start and stop of the motor 41.

[0074] Furthermore, the heating element 51 includes a fixing bar 511 and a heating wire 512 wound around the fixing bar 511. The fixing bar 511 is embedded in the abutting section 322 of one rotating plate 3, and the abutting member 52 is embedded in the abutting section 322 of the other rotating plate 3. The two abutting sections 322 abut against each other via the heating wire 512 and the abutting member 52. It is necessary to define an engaging groove 3221 on each abutting section 322, with each engaging groove 3221 opening toward the other abutting section 322. The fixing bar 511 and the abutting member 52 are respectively engaged in the two engaging grooves 3221.

[0075] Specifically, the rotating blade 3 is made of a high-temperature resistant plastic material. The heating element 51 also includes a first thermal insulation layer 513 that wraps around the fixed bar 511 and the heating wire 512. The fixed bar 511 is provided with a winding groove 5111 around its circumference, and the heating wire 512 is wound in the winding groove 5111. The first thermal insulation layer 513 is made of Teflon tape (a heat-resistant material) and is wrapped around the fixed bar 511. The first thermal insulation layer 513 is exposed only on the side of the first thermal insulation layer 513 facing the other rotating blade 3. The first thermal insulation layer 513 is primarily used to prevent the heating wire 512 from melting the rotating blade 3.

[0076] Furthermore, the abutment member 52 includes a soft base layer 521 and a second thermal insulation layer 522 that wraps around the soft base layer 521. The soft base layer 521 is made of rubber, and the second thermal insulation layer 522 is also made of Teflon tape. The heating wire 512 can abut against the second thermal insulation layer 522 to sandwich the garbage bag 1000. The soft base layer 521 provides soft contact between the heating wire 512 and the abutment member 52, preventing damage to the heating wire 512. The second thermal insulation layer 522 prevents the heating wire 512 from melting the soft base layer 521.

[0077] As attached Figure 14 As shown, the present invention also provides a cat litter box, which includes any of the aforementioned garbage bag sealing devices and a bowl body 2000. The bowl body is used to load cat litter and provide a toilet for cats. The garbage bag sealing device is installed on the side of the bowl body 2000 or in the bowl body 2000, exposing the garbage channel 10. A rake cleaning device 3000 can be provided in the bowl body 2000. The rake cleaning device can be used to dump feces in the bowl body 2000 into a garbage bag, and then the garbage bag sealing device is activated to seal the garbage bag loaded with feces.

[0078] It should be noted that the rake cleaning device 3000 can be composed of a rotating rake 3001 and a translation rake 3002. The translation rake 3002 is used to concentrate the feces blocks in the basin 2000 to the rotating rake 3001, and then the rotating rake 3001 concentrates the feces blocks and dumps them together to the top of the main body 1. The feces blocks fall from the top of the main body 1 into the garbage channel 10. A funnel-shaped structure 4000 can be set above the main body 1 to gather the feces blocks into the garbage channel 10.

[0079] Obviously, the embodiments described above are only some embodiments of the present invention, rather than all embodiments. The preferred embodiments of the present invention are given in the accompanying drawings, but they do not limit the patent scope of the present invention.
