[0002] At present, intelligent 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 the initial 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, including a trash can body, a trash bag storage device is provided above the trash can body, a trash bag feeding device and a trash bag sealing device are provided below the trash bag storage device, the trash bag feeding device and the trash bag sealing device are controlled by a control circuit, the control circuit is connected to a power supply, the trash bag feeding device includes a first trash bag feeding roller and a second trash bag feeding roller which are arranged relatively and can move relative to each other, a trash bag feeding roller driving mechanism is connected to the first trash bag feeding roller or the second trash bag feeding roller, the trash bag sealing device includes a first slide and a second slide which are arranged relatively and can move relative to each other, a trash bag sealing member is provided on the first slide or the second slide, and the trash bag sealing member is located on the end surface where the first slide and the second slide are connected. Relative arrangement means that the first bag-feeding roller and the second bag-feeding roller are located on the left and right sides respectively. When the first bag-feeding roller and the second bag-feeding roller need to feed the garbage bag, the two bag-feeding rollers move from the two sides to the middle. After the two rollers come into contact, the friction between the rollers and the plastic film of the garbage bag tube drives the garbage bag tube to move into the main body of the garbage bin to achieve bag feeding. After the bag feeding is completed, the two bag-feeding rollers can move from the middle to the opposite directions on both sides and return to the initial position. The garbage bag sealing part includes an electric heating round wire, and an electric heating flat wire is provided on one side or both sides of the electric heating round wire. Multiple sealing and cutting can be achieved, making the sealing more reliable.

[0004] For another example, the Chinese invention patent document with authorization announcement number CN111977218B discloses a flexible packaging mechanism for garbage bags and a garbage can, 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 arranged 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, and is used to seal the garbage bag after closing; the closing mechanism includes a flexible belt arranged around the support plate through hole, the head end of the flexible belt is fixedly arranged with the support plate, the middle part bypasses 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 characteristics at least at the part in contact with the sealing end face, and the driving device and the sealing device are communicatively connected with the control device. A flexible belt is used for closing, and the flexible belt is meshed and connected 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 limiting 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 the 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 sealing and packaging quality.

[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, comprises 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 trash bags. Specifically, the upper shell 200 comprises a bottom plate 210, the bottom plate 210 is provided with a material drop opening 211, an inner ring side plate 212 extends upward along the edge of the material drop opening 211, an outer ring side plate 213 extending upward is provided on the bottom plate 210, and 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 trash bags to be heat-sealed. A storage chamber 215 is provided on the outer side of the outer ring side plate 213, which is used to accommodate 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 on the outside of the garbage bag.

[0037] In the automatic packing trash can of the above embodiment, the garbage bag film that is orderly stored can be loaded into the annular cavity 214, and the free end of the garbage bag film can be extended downward into the accommodating cavity 101. The hand strap of the coil is placed in the storage cavity 215, and the free end of the coil is attached to the free end of the garbage bag. Specifically, when the hand strap coil is placed in the storage cavity 215 for the first time or replaced, the free end of the coil can be attached to the outside of the garbage bag film by glue. Therefore, when the garbage bag film is conveyed downward, the hand strap follows the previous downward conveying. And when the heat sealing device 300 heat seals the bottom of the garbage, the hand strap can be heat-sealed and attached to the outside of the garbage bag. When the garbage needs to be heat-sealed and packaged, the heat sealing device 300 heat seals the upper end of the garbage bag, cuts the garbage bag at the same time, and heat seals and cuts the hand strap at the same time. In addition, when the garbage bag and the hand strap are cut, the bottom heat sealing of the next garbage bag can be completed, and the bottom end of the hand strap can be welded to the outside of the lower end of the garbage belt. Therefore, the automatic packing garbage bin can heat-seal the carrying strap to the outside of the garbage bag while heat-sealing and cutting the garbage bag to form a carrying position, which is convenient for picking up the garbage bag.

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

[0039] Further, refer to Figure 2 and Figure 7 The bottom ends of the storage chamber 215 and 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 mutual interference when being transported downward, and the two can be transported downward more smoothly.

[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 cavity 215. The installation opening is pivotally connected to a bottom cover 217 for covering the bottom of the storage cavity 215. When the hand strap roll is placed into the storage cavity 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 also 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, and the annular cavity 214 is covered with the upper cover 220 after loading, so as to limit the garbage bag in the annular cavity 214, avoid the garbage bag from being transported downward, and ensure 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 comprises a housing 400, wherein a mounting cavity 401 is provided in the housing 400, wherein a support plate 410 is provided in the mounting cavity 401, and the upper shell 200 is provided in the mounting cavity 401 and supported on the support plate 410. The heat sealing device 300 is provided at the bottom side of the support plate 410.

[0045] Further, refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 A connecting seat 420 is pivotally connected to the bottom end of one side of the housing 400, and the connecting seat 420 is connected to the barrel body 100; a driving device 500 for driving the housing 400 to rotate and open is arranged in the connecting seat 420. In this embodiment, after the garbage bag is packed, the driving device 500 can drive the housing 400 to rotate upward and open, so as to facilitate 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 the two 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 with 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 groove 402, and the connecting seat 420 is provided with a mounting portion 421 extending upward, the mounting portion 421 extends into the mounting groove 402, and a rotating shaft 440 passes through the mounting portion 421 and is rotatably connected to the two side walls of the mounting groove 402.

The mounting seat includes a first seat body 361, a second seat body 362, a third seat body 363 and a fourth seat body 364 which are arranged diagonally. A first guide rod 365 is connected between the first seat body 361 and the second seat body 362, and a second guide rod 366 is connected between the third seat body 363 and the fourth seat body 364. A third guide rod 367 is connected between the first seat body 361 and the third seat body 363, and a fourth guide rod 368 is connected between the second seat body 362 and the third seat body 363.

The two ends of the fixed clamping plate 320 pass through the guide grooves of the two closing pieces 340 respectively, and are connected to the first guide rod 365 and the second guide rod 366 respectively. The side of the fixed clamping plate 320 is provided with an electric heating element 370. The two ends of the movable clamping plate 330 pass through the guide grooves 341 of the two closing pieces 340 respectively, and are slidably connected to the first guide rod 365 and the second guide rod 366 respectively, so that the movable clamping plate 330, the fixed clamping plate 320 and the two closing pieces 340 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 the same structure and are respectively arranged on the first seat body 361 and the second seat body 362. The first gear assembly 351 and the second gear assembly 352 both include an intermediate gear 301 and a first driven gear 302 and a second driven gear 303 meshing with the intermediate gear 301. The driving motor 310 is connected to the intermediate gear 301 of the first gear assembly 351; the first synchronous belt transmission mechanism 353 is connected to 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 is connected to the second driven wheel 303 of the second gear assembly 352 and the third seat body 363. The third synchronous belt transmission mechanism 355 connects the first driven gear 302 of the first gear assembly 351 and the fourth seat body 364, and the fourth synchronous belt transmission mechanism 365 connects the third seat body 363 and the third synchronous belt transmission mechanism 355.

The synchronous belts of the second synchronous belt transmission mechanism 354 are connected to the same end of the closing member 340, while the synchronous belts of the fifth synchronous belt transmission mechanism 357 are connected to the other ends of the two closing members 340.

[0052] Specifically, when the heat-sealing device 300 of this embodiment heat-seals a garbage bag, the driving motor 310 drives the intermediate gear 301 of the first gear assembly 351, and the intermediate gear 301 of the first gear assembly 351 drives the first driven gear 302 and the second driven gear 303 meshing therewith respectively; the first driven gear 302 drives the first synchronous belt transmission mechanism 353 and the third synchronous belt transmission mechanism 355, and the first synchronous belt transmission mechanism 353 drives the second synchronous belt transmission mechanism 354, and the third synchronous belt transmission mechanism 355 drives the fourth synchronous belt transmission mechanism 365; and the second driven gear 303 of the first gear assembly 351 drives the fifth synchronous transmission mechanism 357. Thus, the two closing members 340 are driven to move toward each other to close the garbage bag, and at the same time, the movable clamping plate 330 moves toward the fixed clamping plate 320 to press the closed garbage bag against the fixed clamping plate 320, and the garbage bag is heat-sealed and cut through 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 of the closed part 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 Fig.10 The electric heating element 370 includes two heat-sealing electric heating wires 371 and a cutting electric heating wire 372, and the cutting electric heating wire 372 is located between the two heat-sealing electric heating wires 371. A tension spring 373 is provided at one end or both ends of the cutting electric heating wire 372 to tighten the cutting electric heating wire 372 to avoid the problem of deformation of the cutting electric heating wire 372 after heating. In addition, when heat-sealing the garbage bag, the two heat-sealing electric heating wires 371 heat-seal on the garbage bag to form two heat-sealing positions, one of which is to heat-seal the mouth of the garbage bag, and the other heat-sealing position is to complete the bottom vent of the next garbage bag. The cutting electric heating wire 372 can divide the garbage bag into two.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
