DETAILED DESCRIPTION
[0033] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.
[0034] like Figure 1-7As shown, in this embodiment, a smart trash can is provided, which uses a non-breakpoint trash bag, and includes a storage device, a controller 5, an overflow detection device 6, and a sealing, cutting, opening and closing assembly 7. The storage device is specifically composed of a lower barrel body 2 and an upper barrel body 1 welded to the top of the lower barrel body 2, and the bottom of the upper barrel body 1 is connected to the top of the lower barrel body 2. The upper barrel body 1 is also provided with an inner barrel body 10 with a diameter smaller than the upper barrel body 1. There is a gap between the inner barrel body 10 and the upper barrel body 1 for placing the non-breakpoint trash bag. When in use, the non-breakpoint trash bag is directly inserted into the gap between the inner barrel body 10 and the upper barrel body 1, and the only bag bottom is placed in the inner barrel body 10 in a conventional manner. The lower barrel body 2 is rotatably connected to the side with a lower barrel door 4. When the trash bag in the inner barrel body 10 is full and falls into the lower barrel body 2, the lower barrel door 4 is opened to take out the trash bag and throw it away. The upper barrel body 1 is covered with an upper barrel cover 3, which is mounted on an overflow detection device 6, which is mounted on one side of the upper barrel body 1. The overflow detection device 6 can control the upper barrel cover 3 to rotate and open. The controller 5 is also mounted on the side wall of the upper barrel body 1. The controller 5 is electrically connected to the overflow detection device 6 and the sealing cutting and opening and closing component 7, and is used to send and receive instructions and control the operation of each energized component. The sealing, cutting, opening and closing component 7 is arranged above the interior of the lower barrel body 2. When the trash can is in normal use, when the upper barrel cover 3 is closed or opened, the sealing, cutting, opening and closing component 7 can carry the upper garbage bag; when the trash can is in an overflowing state, the overflow detection device 6 will be triggered when the upper barrel cover 3 is closed, and then a signal will be transmitted to the sealing, cutting, opening and closing component 7 through the controller 5. The sealing, cutting, opening and closing component 7 will open to allow the full garbage bag to fall into the lower barrel body 2. At the same time, since it is a breakpoint-free garbage bag, the sealing, cutting, opening and closing component 7 will perform double-position sealing and cut-off on the breakpoint-free garbage bag after resetting and closing. The used garbage bag at the bottom can be directly thrown away after being packaged and cut, and the empty garbage bag at the top can be packaged and cut to form a new garbage bag bottom, which can continue to be used. By repeating the process in this way, automatic bagging can be realized. In addition, the length advantage of the breakpoint-free garbage bag allows it to be used continuously for a long period of time without manual intervention. It only requires the garbage bag in the lower barrel body 2 to be directly taken out and thrown away regularly, which greatly improves the convenience of life.
[0035] Specifically, the overflow detection device 6 in this embodiment realizes overflow detection and drives the upper barrel cover 3 to rotate and open and close as follows: the overflow detection device 6 includes a steering gear 61 installed on one side of the upper barrel body 1. The steering gear 61 is a kind of motor, and has output shafts at both ends. Flange couplings 62 are fixedly connected to the output shafts at both ends of the steering gear 61. A columnar connector 63 is installed on each flange coupling 62. A hinge 64 is installed on the top of each columnar connector 63. A concave switch mounting bracket 65 is also welded on the top of one of the columnar connectors 63. A micro switch 66 is installed on the inner side of the top of the switch mounting bracket 65. When the steering gear 61 rotates, it drives the flange couplings 62 at both ends to rotate, and then drives the columnar connectors 63 at both ends to rotate, and the hinges 64 thereon rotate with it, and the switch mounting bracket 65 and the micro switch 66 also rotate together. Two flanges 30 are formed at one end of the upper barrel cover 3, and the two flanges 30 are respectively installed on the upper ends of the two hinges 64. A flange 30 close to the micro switch 66 passes through the switch mounting bracket 65 and is located below the micro switch 66. When the steering engine 61 rotates, the upper barrel cover 3 rotates with the lower hinge 64 to achieve opening and closing. When the upper barrel cover 3 is completely closed or opened, including during the opening process, the two hinges 64 are always in a closed state, and the upper barrel cover 3 is always in close contact with the lower end of the hinge 64 due to gravity. Therefore, during these processes, the upper barrel cover 3 and the micro switch 66 remain parallel and relatively static. When the trash can is in an overflowing state, the upper bucket cover 3 will stop rotating due to the obstruction of the garbage on the top when closing, and cannot be completely closed. At this time, the micro switch 66 and the switch mounting bracket 65 will continue to rotate closer to the original position under the control of the servo 61, and the hinge 64 will also open a certain angle until the upper bucket cover 3 touches the micro switch 66. After receiving the signal, the controller 5 will control the sealing cutting and opening and closing assembly 7 to open so that the full garbage bag falls into the lower bucket body 2, and execute the subsequent process, and the upper bucket cover 3 can also be completely closed.
[0036] In order to prevent the garbage bag from being punctured by some hard and sharp garbage when it falls, a conveyor 8 is also provided inside the lower barrel 2 of the present embodiment. The conveyor 8 is electrically connected to the controller 5. The sealing, cutting, opening and closing assembly 7 is installed on the conveyor 8. When the garbage can is in an overflowing state, in addition to the sealing, cutting, opening and closing assembly 7 slowly opening, the garbage bag will not fall all at once. At the same time, the controller 5 will also control the conveyor 8 to drive the sealing, cutting, opening and closing assembly 7 to move slowly downward. When the sealing, cutting, opening and closing assembly 7 moves down to half the height, it can also be fully opened at this time. At this time, the garbage bag will completely fall into the lower barrel 2. Under the influence of the falling height and the height of the opening of the sealing, cutting, opening and closing assembly 7, the garbage bag will fall at a very low height at this time, and will not be damaged or punctured. After the garbage bag falls completely, the conveyor 8 will drive the sealing, cutting, opening and closing assembly 7 to slowly move up and back to its position, and the sealing, cutting, opening and closing assembly 7 will also slowly close. After it is completely returned to its position and closed, the sealing and cutting work will be performed.
[0037] Specifically, the sealing, cutting, opening and closing assembly 7 in this embodiment realizes sealing, cutting and carrying opening and closing in the following manner: the sealing, cutting, opening and closing assembly 7 comprises two garbage carrying plates 72 and two hot-melt seals 73. The two garbage carrying plates 72 are respectively mounted on the conveying device 8 through electric hinges 71. The electric hinges 71 have built-in motors and are controlled to open and close by the controller 5. The two garbage carrying plates 72 can be opened and closed under the drive of the electric hinges 71. The two hot-melt seals 73 are respectively mounted on one end of the two garbage carrying plates 72 that are close to each other. When the two garbage carrying plates 72 are closed, they play the role of supporting the upper garbage bag, and when they are unfolded, the garbage bag can fall. After the garbage bag falls completely and the two garbage carrying plates 72 are restored to their original positions and closed, the two hot-melt seals 73 perform double sealing and cutting on the garbage bag.
[0038] Specifically, the hot melt seal 73 in this embodiment is implemented as follows: the hot melt seal 73 is specifically divided into a sealing layer 731 at the upper and lower ends and a cutting layer 730 in the middle. The sealing layers 731 at the upper and lower ends are first sealed and packaged, and then the cutting layer 730 in the middle is cut and cut to achieve the upper and lower separation of the garbage bag without breakpoints. The sealing layer 731 and the cutting layer 730 are both treated by electric heating at high temperature. The temperature of the sealing layer 731 is not particularly high, just enough to achieve hot melt adhesive sealing, while the temperature of the cutting layer 730 is relatively high, just enough to burn the garbage bag. The advantage of using the hot melt seal 73 is that the structure is simple and one-step. Of course, in other embodiments, other devices can also be used to replace the hot melt seal 73, such as a combination of a traditional steel belt packer and a cutting tool.
[0039] Specifically, the conveying device 8 in this embodiment drives the sealing, cutting and opening and closing assembly 7 to move up and down in the following manner: the conveying device 8 is specifically composed of two screw drive motors 83 installed at both ends of the bottom of the lower barrel 2, two screws 82 respectively connected to the output shafts of the two screw drive motors 83, two baffles 80 installed inside the lower barrel 2 and connected to the lower barrel 2 up and down, and two sliding adapter plates 81 respectively slidably sleeved on the two baffles 80. The two baffles 80 are respectively close to the two screw drive motors 83. The main function of the baffles 80 is to protect the screw 82 and the screw drive motor 83 from being interfered with by the garbage bag, and at the same time, it also has the function of limiting the position of the two sliding adapter plates 81. The two sliding adapter plates 81 are respectively connected to the two screws 82 through screw nuts, and the two garbage carrying plates 72 are respectively installed on the two sliding adapter plates 81 through electric hinges 71. The two screw drive motors 83 are controlled by the controller 5 to rotate, drive the two screws 82 to rotate, and then drive the two sliding adapter plates 81 to move up and down. Polish rods can also be set on both sides of the screw 82 to make the sliding adapter plate 81 more stable and accurate when moving up and down.
[0040] In order to facilitate sealing and packaging and convenient packaging and cutting, a screwing device 9 is further provided inside the lower barrel body 2 of the present embodiment. The screwing device 9 is electrically connected to the controller 5. Before the garbage bag is sealed, that is, when the two garbage carrying plates 72 are about to be completely closed, the screwing device 9 is controlled to tighten the mouth of the garbage bag. After that, it will be much more convenient to seal and cut, and it can also be more secure.
[0041] Specifically, the mouth-tightening device 9 of this embodiment is composed of a tray driving motor 92 installed at the bottom of the lower barrel 2 and a tray 91 installed at the output end of the tray driving motor 92. When the garbage bag falls, it will fall on the tray 91. Before the garbage bag is sealed, the tray driving motor 92 rotates, driving the tray 91 to rotate, and the mouth of the garbage bag can be tightened, which is efficient and convenient.
[0042] In order to facilitate the automatic opening of the upper bucket cover 3 when throwing away garbage, infrared sensing technology can be used. In this embodiment, an infrared sensing device is installed on the front side wall of the upper bucket body 1, and the infrared sensing device can transmit a signal to the controller 5 to realize the lid opening operation. In this way, when a person arrives in front of the garbage bin and prepares to throw away garbage, the upper bucket cover 3 can be automatically opened, eliminating the step of manually opening the lid, which is convenient and clean.
