Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent trash cans, and in particular relates to an automatic packing trash can. Background Art

[0002] At present, smart home products are constantly improving people's quality of life, and smart trash cans are one of them. Trash cans are a household product that people often use in their daily lives. As people pursue higher and higher quality home environments, they have gradually evolved from simple trash cans to modern smart trash cans.

[0003] For example, the Chinese invention patent document with authorization publication number CN109319332B discloses an automatically sealed trash can, comprising a trash can main body, a trash bag storage device provided above the trash can main body, a trash bag feeding device and a trash bag sealing device provided below the trash bag storage device, the trash bag feeding device and the trash bag sealing device being controlled by a control circuit, the control circuit being connected to a power supply, the trash bag feeding device comprising a first and a second bag feeding roller which are arranged relatively and can move relative to each other, a bag feeding roller driving mechanism being connected to the first and the second bag feeding rollers, the trash bag sealing device comprising a first slide and a second slide which are arranged relatively and can move relative to each other, a trash bag sealing member being provided on the first slide or the second slide, the trash bag sealing member being located on the end surface where the first slide and the second slide are connected. The relative arrangement means the first and second rollers are located on the left and right sides, respectively. When the garbage bags are to be loaded, the first and second rollers move from opposite sides toward the center. Once the two rollers make contact, the friction between the rollers and the plastic film of the bag material propels the bag material into the trash can body, allowing it to be loaded. Once loaded, the two rollers can then move from the center toward the sides in opposite directions before returning to their initial positions. The garbage bag sealing element consists of a round electric heating wire with a flat electric heating wire attached to one or both sides. This allows for multiple sealing and cutting operations, ensuring a more reliable seal.

[0004] For example, the Chinese invention patent document with authorization publication number CN111977218B discloses a flexible packaging mechanism for garbage bags and a garbage bin, including a support plate, a driving device, a closing mechanism, and a sealing device arranged on the support plate, wherein: the support plate is provided with a support plate through hole for garbage bags and garbage to pass through, a flexible belt limiting groove is provided on the support plate around the support plate through hole, the driving device includes a motor and a reduction transmission gear driven by the motor, and the sealing device is fixedly arranged at a position on one side of the support plate through hole, for sealing the closed garbage bag; the closing mechanism includes a flexible belt arranged around the support plate through hole, the head end of the flexible belt is fixed to the support plate, the middle part passes around the sealing end face of the sealing device and is meshed with the reduction transmission gear, and the end moves back and forth along the flexible belt limiting groove with the rotation of the reduction transmission gear, so that the rotation of the reduction transmission gear can drive the flexible belt to tighten or reset around the sealing device; the flexible belt has high-temperature resistant insulation properties at least at the part in contact with the sealing end face, and the driving device and the sealing device are communicatively connected to the control device. A flexible belt is used for closing, and the flexible belt is meshed with the reduction transmission gear device of the driving device. Under the driving action of the driving device and the guiding and limiting action of the flexible belt limit groove, the garbage bag can be effectively gathered to the sealing end surface, and cooperate with the sealing device to realize the packaging and sealing operation. Compared with the existing flexible packaging mechanism for garbage bags with rigid pressure rod packaging and sealing, the flexible packaging mechanism for garbage bags of the present invention has fewer structural parts, which greatly reduces the processing and assembly accuracy requirements for each spare part, reduces production and assembly costs, and has a simplified structure, a low failure rate, and better reliability. At the same time, when the amount of garbage in the garbage bag exceeds the closing plane, the flexible packaging mechanism for garbage bags of the present invention can still achieve good sealing and packaging while ensuring the quality of sealing and packaging.

[0005] It can be seen that the technical solutions in the above patent documents all realize automatic heat-sealing and packaging of garbage bags. However, after the garbage bags are heat-sealed and cut, there is no hand-held position for the garbage bags, which is inconvenient to pick up when there is too much garbage in the garbage bags.

For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0036] In one embodiment of the automatic packing trash can of the present invention, please refer to Figures 1 to 10 , an automatic packing trash can, includes a barrel body 100, an upper shell 200 and a heat sealing device 300. A accommodating chamber 101 is provided in the barrel body 100, and the upper shell 200 is provided at the top of the barrel body 100 and covers the accommodating chamber 101. The heat sealing device 300 is provided on the bottom side of the upper shell 200 and is used for heat-sealing and packing garbage bags. Specifically, the upper shell 200 includes a bottom plate 210, and the bottom plate 210 is provided with a blanking port 211. An inner ring side plate 212 extends upward along the edge of the blanking port 211, and an outer ring side plate 213 extending upward is provided on the bottom plate 210. The outer ring side plate 213 and the inner ring side plate 212 form an annular chamber 214, and the annular chamber 214 is used to store the garbage bags to be heat-sealed. A storage chamber 215 is provided on the outside of the outer ring side plate 213 for accommodating a hand strap. When the garbage bag in the annular cavity 214 is transported into the accommodating cavity, the hand belt in the storage cavity 215 can be transported downward along with the garbage bag, so that the heat sealing device 300 heat-seals the hand belt to the outside of the garbage bag.

[0037] In the automatic trash can of the aforementioned embodiment, the neatly stored trash bag film can be loaded into the annular cavity 214, with the free end of the film extending downward into the accommodating cavity 101. A roll of the hand strap is placed in the storage cavity 215, with the free end of the roll attached to the free end of the trash bag. Specifically, when the hand strap roll is first or replaced in the storage cavity 215, the free end of the roll can be attached to the outside of the trash bag film using adhesive. Therefore, as the trash bag film is conveyed downward, the hand strap follows it. Furthermore, while the heat-sealing device 300 heat-seals the bottom of the trash, the hand strap can be heat-sealed to the outside of the trash bag. To heat-seal and pack the trash, the heat-sealing device 300 heat-seals the top of the trash bag, simultaneously cutting the bag and heat-sealing and cutting the hand strap. Furthermore, while the trash bag and hand strap are cut, the bottom of the next trash bag is heat-sealed, and the bottom end of the hand strap is welded to the outside of the lower end of the trash strap. Therefore, the automatic packing trash can can heat-seal the handle belt to the outside of the trash bag while heat-sealing and cutting the trash bag to form a handle position, which is convenient for picking up the trash bag.

[0038] Preferably, two or more hand straps can be placed in the storage cavity 215 .

[0039] Further, refer to Figure 2 and Figure 7 The bottom of the storage chamber 215 and the bottom of the annular chamber 214 are both provided with a clearance groove 216, and the hand strap in the storage chamber 215 passes through the clearance groove 216 and extends into the accommodating chamber 101. Therefore, the garbage bag and the hand strap avoid interference with each other when being transported downward, making the downward transportation of the two more smooth.

[0040] Further, refer to Figure 6 and Figure 7 The bottom plate 210 is provided with an installation opening, which is located at the bottom of the storage chamber 215. The installation opening is pivotally connected to a bottom cover 217 for covering the bottom of the storage chamber 215. When the hand strap roll is placed into the storage chamber 215, the bottom cover 217 can be opened and then closed.

[0041] Furthermore, when the bottom cover 217 covers the installation opening, an air-avoiding groove 216 is formed. Therefore, after the hand strap is loaded into the storage cavity 215, the free end of the hand strap is pulled out and attached to the outside of the garbage bag, and then the bottom cover 217 is closed, thereby facilitating the hand strap to be loaded into the storage cavity 215.

[0042] Further, refer to Figure 2 and Figure 7 An arc-shaped limiting plate 218 is further provided in the storage cavity 215. When the hand strap is loaded into the storage cavity 215, the arc-shaped limiting plate 218 limits the hand strap coil.

[0043] Further, refer to Figure 2 、 Figure 6 and Figure 7 The top of the annular cavity 214 is also provided with an upper cover 220, which is pivotally connected to the outer ring side plate 213 and is used to cover the annular cavity 214 and the storage cavity 215. Therefore, the garbage bag film can be loaded into the annular cavity 214 from the top side. After loading, the annular cavity 214 is covered with the upper cover 220, thereby limiting the position of the garbage bag in the annular cavity 214, preventing the garbage bag from being transported downward, and ensuring that the garbage bag can be transported downward in an orderly manner.

[0044] Further, refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The automatic packing trash can further includes a housing 400, which has a mounting cavity 401 therein, a support plate 410 therein, and the upper shell 200 is disposed in the mounting cavity 401 and supported on the support plate 410. The heat sealing device 300 is disposed on the bottom side of the support plate 410.

[0045] Further, refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 A connecting base 420 is pivotally connected to the bottom end of one side of the housing 400, and the connecting base 420 is connected to the barrel body 100. A driving device 500 is installed in the connecting base 420 to drive the housing 400 to rotate and open. In this embodiment, after the garbage bag is packed, the driving device 500 can drive the housing 400 to rotate upward and open, thereby facilitating the removal of the garbage bag from the barrel body 100.

[0046] Further, refer to Figures 2 to 5 A limiting groove 102 is provided in the accommodating cavity 101, and the connecting seat 420 is provided in the limiting groove 102. An elastic telescopic rod 430 is provided in the connecting seat 420, and the two ends of the elastic telescopic rod 430 extend from both sides of the connecting seat 420. The two side walls of the limiting groove 102 are provided with limiting holes 103 for limiting the elastic telescopic rod 430. The elastic telescopic rod 430 is also connected to a push plate 431 for pushing the two ends of the elastic telescopic rod 430 to retract inward and disengage from the limiting holes 103. Specifically, an air avoidance gap is provided on the back side of the barrel body 100, and the air avoidance gap is used to avoid the air push plate 431. Therefore, in the solution of this embodiment, the shell 400 and the barrel body 100 can be disassembled, and the barrel body 100 can be cleaned. Specifically, when disassembling the outer shell 400, the push plate 431 can be pressed to cause the elastic telescopic rod 430 to contract and disengage from the limiting hole 103, so that the connecting seat 420 can be pulled out from the limiting groove 102, so that the barrel body 100 and the outer shell 400 are separated as a whole, and the barrel body 100 can be cleaned, etc.

[0047] Further, refer to Figure 2The bottom side of the housing 400 is provided with a mounting slot 402. The connecting base 420 is provided with an upwardly extending mounting portion 421 that extends into the mounting slot 402. A rotating shaft 440 passes through the mounting portion 421 and is rotatably connected to the two side walls of the mounting slot 402. The mounting portion 421 defines a cavity 422, and the drive unit 500 is disposed within the cavity 422. The drive unit 500 includes a motor 510 and a transmission gear 520 that connects the rotating shaft 440 and the motor 510. The connecting base 420 also houses a battery 450 and an exhaust device 460. The lower end of the connecting base 420 is provided with an exhaust hole 423, and the bottom is provided with an exhaust hole 424. Preferably, the bottom of the barrel 100 is provided with an air vent. In this embodiment, when the garbage bag is conveyed downward, the exhaust device 460 creates a negative pressure within the receiving chamber 101. Under the action of the negative pressure, the garbage bag is conveyed downward and simultaneously adheres to the inner wall of the receiving chamber.

[0048] Going further, refer to Figure 1 In order to better prevent the odor in the trash can from being emitted, a sealing cover 600 is provided on the outer shell 400, and the sealing cover 600 is pivotally connected to the outer shell 400 and can be opened by a motor drive to achieve driven opening.

[0049] Further, refer to Figures 8 to 10 The heat sealing device 300 includes a drive motor 310, a mounting base, a fixed clamping plate 320, a movable clamping plate 330, a closing member 340, and a transmission assembly 350. The mounting base includes a first base 361, a second base 362, a third base 363, and a fourth base 364, which are arranged diagonally. A first guide rod 365 is connected between the first base 361 and the second base 362, and a second guide rod 366 is connected between the third base 363 and the fourth base 364. A third guide rod 367 is connected between the first base 361 and the third base 363, and a fourth guide rod 368 is connected between the second base 362 and the third base 363.

[0050] The two sets of closing members 340 are slidably connected to a third guide rod 367 and a fourth guide rod 368. The closing members 340 are provided with guide grooves 341 extending along their lengths. The two ends of the fixed plate 320 extend through the guide grooves of the two closing members 340 and are connected to the first guide rod 365 and the second guide rod 366, respectively. Electric heating elements 370 are provided on the sides of the fixed plate 320. The two ends of the movable plate 330 extend through the guide grooves 341 of the two closing members 340 and are slidably connected to the first guide rod 365 and the second guide rod 366, respectively. This allows the movable plate 330, the fixed plate 320, and the two closing members 340 to form a heat-sealed shrink structure.

[0051] The transmission assembly 350 includes a first gear assembly 351, a second gear assembly 352, a first synchronous belt transmission mechanism 353, a second synchronous belt transmission mechanism 354, a third synchronous belt transmission mechanism 355, a fourth synchronous belt transmission mechanism 356, and a fifth synchronous belt transmission mechanism 357. The first gear assembly 351 and the second gear assembly 352 have identical structures and are mounted on a first base 361 and a second base 362, respectively. Both the first and second gear assemblies 351 and 352 include an intermediate gear 301 and a first and second driven gears 302 and 303 meshing with the intermediate gear 301. The drive motor 310 is connected to the intermediate gear 301 of the first gear assembly 351; the first synchronous belt transmission mechanism 353 connects the first driven gear 302 of the first gear assembly 351 and the first driven gear 301 of the second gear assembly 352. The second synchronous belt transmission mechanism 354 connects the second driven gear 303 of the second gear assembly 352 and the third base 363. The third synchronous belt transmission mechanism 355 connects the first driven gear 302 of the first gear assembly 351 and the fourth seat 364. The fourth synchronous belt transmission mechanism 365 connects the third seat 363 and the third synchronous belt transmission mechanism 355. The fifth synchronous belt transmission mechanism 357 connects the second driven gear 303 of the first gear assembly 351 and the fourth seat 364. The synchronous belts of the first and third synchronous belt transmission mechanisms 353 and 354 are respectively connected to the two ends of the movable splint 330. The synchronous belt of the second synchronous belt transmission mechanism 354 is connected to the same end of the closing member 340, while the synchronous belt of the fifth synchronous belt transmission mechanism 357 is connected to the other ends of both closing members 340.

[0052] Specifically, when heat-sealing a garbage bag, the heat-sealing device 300 of this embodiment drives the motor 310 to drive the intermediate gear 301 of the first gear assembly 351. The intermediate gear 301 of the first gear assembly 351 drives the first driven gear 302 and the second driven gear 303 meshing therewith. The first driven gear 302 drives the first synchronous belt drive mechanism 353 and the third synchronous belt drive mechanism 355. The first synchronous belt drive mechanism 353 in turn drives the second synchronous belt drive mechanism 354, which in turn drives the fourth synchronous belt drive mechanism 365. Furthermore, the second driven gear 303 of the first gear assembly 351 drives the fifth synchronous drive mechanism 357. This drives the two closing members 340 toward each other, closing the garbage bag. Simultaneously, the movable clamping plate 330 moves toward the fixed clamping plate 320, pressing the closed garbage bag against the fixed clamping plate 320. The garbage bag is heat-sealed and severed by the electric heating element 370.

[0053] Furthermore, since the closing member 340 is provided with a guide groove 341, and the fixed clamping plate 320 and the movable clamping plate 330 pass through the guide groove 341, when the two closing members 340 are closed, both ends of the electric heating element 370 can extend into the guide groove 341, so that the garbage bag in the closed portion can be completely closed within the heating range of the electric heating element 370, thereby ensuring that the garbage bag can be completely heat-sealed.

[0054] Furthermore, the meshing gear ratio of the intermediate gear 301 to the first driven gear 302 and the second driven gear 303 is determined according to the movement stroke of the closing member 340 and the movable clamping plate 330 .

[0055] Further, refer to Figure 8 and Figure 10 The electric heating element 370 includes two heat-sealing heating wires 371 and a cutting heating wire 372, with the cutting heating wire 372 located between the two heat-sealing heating wires 371. A tension spring 373 is provided at one or both ends of the cutting heating wire 372 to tighten the cutting heating wire 372 and prevent deformation of the cutting heating wire 372 after heating. Furthermore, when heat-sealing a garbage bag, the two heat-sealing heating wires 371 form two heat-sealing positions on the garbage bag: one heat-sealing position seals the mouth of the garbage bag, and the other heat-sealing position completes the bottom vent of the next garbage bag. The cutting heating wire 372 can then split the garbage bag in two.
