Description

Technical Field

[0001] The utility model belongs to the technical field of trash cans and relates to an intelligent trash can. Background Art

[0002] Trash cans are commonly used products for users to dispose of discarded garbage. When the garbage bag in the trash can is full of garbage, it can be taken out and discarded. With the continuous improvement of intelligent technology, trash cans are also constantly updated.

[0003] For example, a safety automatic trash can has been designed and patented in China, with application number 201110405816.9 and publication number CN102514862A. This safety automatic trash can primarily consists of a body, a lid-opening device, an inner barrel, an inner barrel lifting and driving device, a sealing and cutting device, a bag storage device, and a trash discharge device. The lid-opening device is hingedly mounted on the body, the inner barrel is located within the body and connected to the inner barrel lifting and driving device, the sealing and cutting device is mounted on the upper portion of the inner barrel, the bag storage device is located at the upper end of the body and below the lid, and the trash discharge device is mounted on a flat plate at the lower portion of the body. The inner barrel is mounted with a lead screw and a smooth horizontal guide rail, with the constricting plate and constricting plate mounted on the lead screw and horizontal guide rail. The lead screw has a left-handed thread on one end and a right-handed thread on the other end, with the other parameters of the threads on both ends being identical. The lead screw is driven by a lead screw motor mounted on the inner barrel. The forward and reverse rotation of the lead screw motor drives the two closing pieces symmetrically closer or farther apart. The closing pieces are equipped with an upper encapsulated heating wire, a cut-off heating wire, and a lower encapsulated heating wire. When the closing pieces and the closing pieces clamp the garbage bag, the upper encapsulated heating wire heats the bottom of a new garbage bag, the lower encapsulated heating wire heats the top of a garbage bag already filled with garbage, and the cut-off heating wire heats the garbage bag. This safe automatic trash can automatically seals the garbage bag by bringing the two closing pieces together, then cuts the bag with the cut-off heating wire, and finally seals the bag with the lower encapsulated heating wire. This makes it easier for users to remove the garbage bag.

[0004] However, during the use of the above-mentioned garbage bag, its bag opening is completely open. When the two parallel converging pieces in the shape of long rods move towards each other, the bag opening of the garbage bag will be clamped into a flat shape. Then, after the heating wire and the lower packaging electric heating wire are cut off to cut and seal the garbage bag, the bag opening position of the garbage bag will inevitably still be flat. When the user takes out the garbage bag, he can only grab one point of the flat bag opening, which is not only inconvenient to grab but also easy to cause damage to the manual grabbing position due to the garbage bag being too heavy. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems existing in the prior art and to propose an intelligent trash can, which solves the problem that the bag opening of the existing trash can is flat when the bag opening is sealed.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] The intelligent trash can comprises a trash can body with an open top and a trash can cover provided on the top of the trash can body, wherein the trash can cover has a accommodating cavity for placing a trash bag, and is characterized in that the trash can cover comprises a middle cover in the shape of a square ring and a top cover hinged on the middle cover at the rear, the inner side of the middle cover is open, a heating and cutting piece, a packaging driving piece, and a long and horizontally arranged fork 1, fork 2 and a push rod are provided in the middle cover, the fork 1 and fork 2 are respectively provided on both sides of the middle cover, the front ends of the fork 1 and fork 2 are respectively rotatably connected to the front part of the middle cover, the rear ends of the fork 1 and fork 2 extend into the rear part of the middle cover, the push rod is provided at the front part of the middle cover, the heating and cutting piece is provided at the rear part of the middle cover and is opposite to the push rod, the heating and cutting piece is closer to the push rod than the rear ends of the fork 1 and fork 2, and the packaging driving piece can drive the rear ends of the fork 1 and fork 2 to approach each other and drive the push rod to move backward.

[0008] In this smart trash can, the user-friendly side is the front. During normal use, the front end of the top lid is lifted backward around a hinged position at the rear to open the inner hole of the middle lid, allowing trash to be discarded into a trash bag within the can. The trash bag is a conventional structure that, when fully unfolded, forms a cylindrical shape. When the trash bag within the can needs to be packed, the packaging driver drives forks 1 and 2 to swing around the front end so that their rear ends approach each other, thereby closing the rear end of the trash bag. Forks 1, 2, and the push rod are arranged in a triangular shape. Simultaneously, the packaging driver drives the push rod to move horizontally backward, pushing the front end of the trash bag backward and toward it along the inclined forks 1 and 2. When the push rod reaches the heated cutting element, the bag's opening folds and closes to reduce its diameter. The heated cutting element then heats and cuts the bag, simultaneously sealing the upper and lower portions of the cut portion, completing the packaging of the trash bag.

[0009] During this packaging process, the first and second forks rotate around the front end and move closer to each other, so that the distance between the first and second forks gradually decreases from front to back. At the same time, the rearward movement of the push rod is used to fold and gather the bag opening of the garbage bag to a point, and finally, after cutting, a packaged garbage bag with a larger bottom and a smaller top is formed, which is roughly the same as the garbage bag formed by the existing lacing method, which is convenient for users to grab and carry. Moreover, the thickness of the bag opening of the folded and gathered garbage bag is larger, and it is not easy to be damaged even if the user carries it by hand.

[0010] In the aforementioned smart trash can, both ends of the push rod are provided with a first clearance opening along the front-to-back direction. The front ends of the first and second forks extend through two corresponding first clearance openings, and the rear ends of the first and second forks extend through the sides of the forks along the horizontal direction. The two sides of the heated cut-off element can each extend through two corresponding second clearance openings. The provision of the first and second clearance openings reduces interference between the first and second forks, the push rod, and the heated cut-off element, allowing them to be roughly aligned at the same height. This not only reduces space usage but also facilitates smooth closing and cutting of the garbage bag, ensuring the reliability of the sealed garbage bag.

[0011] In the above-mentioned smart trash can, the smart trash can also includes belt 1, belt 2, belt 3, and gear 1, gear 2, gear 3, and gear 4, which are distributed in sequence at the four corners of the above-mentioned middle cover. Gear 1 and gear 4 are both located at the front of the middle cover. Belt 1 is wound around the outside of gear 1 and gear 2, belt 2 is wound around the outside of gear 2 and gear 3, and belt 3 is wound around the outside of gear 3 and gear 4. The two ends of the push rod are respectively fixed to belt 1 and belt 3, and the rear ends of fork 1 and fork 2 are respectively fixed to belt 2. The four gears are selected to have a larger axial length to allow for the belts to be wound in an offset manner in the upper and lower positions. For example, if belt 1 and belt 2 need to be wound around gear 2, belt 1 can be wound around the bottom of gear 2, and belt 2 can be wound around the top of gear 2. The encapsulated drive member can be connected to any of the four gears in a transmission manner.

[0012] In the aforementioned smart trash can, the first fork comprises two elongated rods, one fork and one fork. The front end of the first fork is rotatably connected to the front of the middle lid, the rear end of the first fork is hinged to the front end of the second fork, and the second fork can swing horizontally about the hinge point. The second fork comprises two elongated rods, one fork and one fork. The front end of the fourth fork is rotatably connected to the front of the middle lid, the rear end of the fourth fork is hinged to the front end of the third fork, and the third fork can swing horizontally about the hinge point. Both the first and second forks have a two-stage structure, making them more flexible during horizontal swinging.

[0013] In the aforementioned smart trash can, the rear portion of the middle lid is hinged to the top of the can body. The smart trash can also includes a first driver that drives the top lid to swing about a hinge point, and a second driver that drives the middle lid to swing about a hinge point. Driver one drives the top lid to swing about the hinge point, opening and closing the inner hole of the middle lid for discarding trash or closing the trash can. Driver two drives the middle lid to swing about the hinge point, opening the top of the can body and facilitating the removal of sealed trash bags.

[0014] In the aforementioned smart trash can, a through-hole is formed through the back of the canister, and a fan is fixed to the back of the canister corresponding to the position of the through-hole. After the trash bag is removed, the middle and top lids are closed, and the fan is activated to draw air, creating a negative pressure inside the canister, pulling the sealed bottom of the trash bag downward to complete the automatic bagging process.

[0015] Compared with the existing technology, during the packaging process of this smart trash can, the first and second forks are moved closer to each other by rotating around the front end, so that the distance between the first and second forks is gradually reduced from front to back. At the same time, the bag opening of the garbage bag is folded and gathered to a point by utilizing the backward movement of the push rod, and finally a packaged garbage bag with a larger bottom and a smaller top is formed after cutting. The bag is roughly the same as the garbage bag formed by the existing lacing method, which is convenient for users to grab and carry. Moreover, the bag opening of the folded and gathered garbage bag is thicker, and it is not easy to be damaged even if the user carries it by hand. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] For the convenience of structural description, the side of the smart trash can facing the user when it is opened for the user to discard trash is referred to as the front side.

[0023] like Figure 1As shown, this smart trash can includes a barrel body 1 with an open top and a barrel cover 2 arranged on the top of the barrel body 1. The barrel cover 2 has a storage cavity 21a for placing garbage bags. Among them, the barrel body 1 is a square barrel, and the barrel cover 2 includes a middle cover 21 in the shape of a square ring and a top cover 22 hinged to the top of the middle cover 21 at the rear. The top cover 22 is located above the middle cover 21 and can cover the upper end of the inner hole of the middle cover 21. The inner side of the middle cover 21 is open, and the storage cavity 21a is located on the inner side of the middle cover 21 and is connected to the inner hole of the middle cover 21. The storage cavity 21a contains a rolled garbage bag. A through hole 1a is opened on the rear side of the bottom of the barrel body 1.

[0024] like Figure 4 As shown, the rear portion of the middle cover 21 is hinged to the top rear side of the trash can body 1. The smart trash can also includes a driving member 16 that can drive the top cover 22 to swing around the hinge point, and a driving member 2 17 that can drive the middle cover 21 to swing around the hinge point. A fan 18 is fixed to the rear of the trash can body 1, corresponding to the position of the through hole 1a.

[0025] In this embodiment, driving member 1 16 and driving member 2 17 are both motors, and transmission gears are fixed to their output ends. Arc-shaped racks are fixed to the middle cover 21 and the top cover 22, and the two racks are respectively engaged with the gears at the output ends of driving member 1 16 and driving member 2 17, so as to drive the top cover 22 or the middle cover 21 to flip upward around the hinge point when the motor is working. Magnets are fixed to the two racks, and a Hall sensor that can detect the positions of the two magnets is fixed in the middle cover 21 to detect whether the top cover 22 and the middle cover 21 reach the set position after rotation to control the motor to stop working.

[0026] like Figure 2 As shown, the middle cover 21 is provided with a heating and shutoff component 3, a packaged driving component 4, and a horizontally arranged shift fork 1 5, a shift fork 2 6, and a push rod 7, all of which are elongated. Shift fork 1 5 and shift fork 2 6 are respectively provided on the left and right sides of the middle cover 21. The push rod 7 is arranged in the left-right direction and is provided at the front of the middle cover 21. The heating and shutoff component 3 is fixed at the center of the rear of the middle cover 21 and is opposite to the push rod 7. Limiting shafts are vertically fixed to the left and right sides of the front of the middle cover 21. The front ends of shift fork 1 5 and shift fork 2 6 each have a vertically opened limiting hole. The front ends of shift fork 1 5 and shift fork 2 6 are correspondingly sleeved on the outside of the two limiting shafts. The width and length of the limiting hole are both greater than the width and length of the limiting shaft, so that the rear ends of shift fork 1 5 and shift fork 2 6 can freely rotate around the limiting shaft. The rear ends of shift fork 1 5 and shift fork 2 6 extend into the rear of the middle cover 21. The heating and shutoff member 3 is closer to the push rod 7 than the rear ends of the first and second forks 5 and 6. The packaged driver 4 can drive the rear ends of the first and second forks 5 and 6 toward each other and drive the push rod 7 to translate backward. In this embodiment, the position of the accommodating chamber 21a is higher than the positions of the first and second forks 5 and 6.

[0027] Specifically, the smart trash can also includes belt 1 9, belt 2 10, belt 3 11, and horizontally rotatable gears 1 12, 2 13, 3 14, and 4 15, which are sequentially distributed at the four corners of the middle cover 21. Gear 1 12 and 4 15 are both located at the front of the middle cover 21. Belt 1 9 is wound around the outside of the lower portions of Gear 1 12 and Gear 2 13, belt 2 10 is wound around the outside of the upper portions of Gear 2 13 and Gear 3 14, and belt 3 11 is wound around the outside of the lower portions of Gear 3 14 and Gear 4 15, so that the three belts are alternately wound around the outside of the four gears. The two ends of the push rod 7 are respectively fixed to the right side portions of belt 1 9 and belt 3 11. The rear ends of the shift fork 1 5 and shift fork 2 6 are respectively fixed to belt 2 10. The rear end of the shift lever 1 is fixed to the front portion of belt 2 10, and the rear end of the shift lever 2 is fixed to the rear portion of belt 2 10. In this embodiment, the package drive member 4 is a motor and meshes with the gear 3 14 via a gear train. The heating and shut-off member 3 includes a mounting base fixed to the middle cover 21 and a heating wire fixed to the front side of the mounting base. The shift fork 1 5 includes a first rod 51 and a second rod 52, both of which are elongated strips. The front end of the first rod 51 is sleeved outside the limit shaft, and the rear end of the first rod 51 is hinged to the front end of the second rod 52, allowing the second rod 52 to swing horizontally about the hinge point. The shift fork 2 6 includes a third rod 61 and a fourth rod 62, both of which are elongated strips. The front end of the fourth rod 62 is sleeved outside the limit shaft, and the rear end of the fourth rod 62 is hinged to the front end of the third rod 61, allowing the third rod 61 to swing horizontally about the hinge point.

[0028] like Figure 3 As shown, in order to ensure that the heating and cutting-off piece 3, the shift fork 1 5, the shift fork 2 6 and the push rod 7 are approximately at the same height, both ends of the push rod 7 are penetrated by a clearance opening 1 7a along the front-to-back direction, the front ends of the shift fork 1 5 and the shift fork 2 6 pass through the two clearance openings 1 7a respectively, and the sides of the rear ends of the shift fork 1 5 and the shift fork 2 6 are penetrated by a clearance opening 2 8 along the left-right direction, and the two sides of the heating and cutting-off piece 3 can pass through the two clearance openings 2 8 respectively.

[0029] To ensure proper operation, this smart trash can features a built-in power supply or an optional plug for connection to mains electricity. The front of the smart trash can also features a display showing the battery level or power status, a power switch, and a packing switch. An infrared sensor is installed on the top of the smart trash can. The body 1 comprises a barrel and a backplate secured to the rear of the barrel with screws. A space is formed between the backplate and the barrel for the control circuit board, which also houses the fan 18. A timer is integrated into the control circuit board. Each motor has a module capable of detecting the motor's stall current. This module, currently available, allows the control circuit board to determine the motor's status.

[0030] During normal use, this smart trash can is connected to a power source and turned on. The display shows the battery level or power-on status. When the user's hand approaches the top of the smart trash can, the infrared sensor detects the object's approach, and the driver 16 drives the top cover 22 upward, opening the inner hole of the middle cover 21. The user can then discard trash through the inner hole of the middle cover 21 into the trash bag inside the trash can body 1. After discarding, if the infrared sensor does not detect an object for three seconds, the driver 16 drives the top cover 22 downward to cover the inner hole of the middle cover 21.

[0031] When the garbage bags in the barrel 1 need to be packed, the packing switch is pressed, and the packing drive 4 is activated, driving gear 1 12, gear 2 13, gear 3 14, and gear 4 15 to rotate, thereby driving belt 1 9, belt 2 10, and belt 3 11 to transmit synchronously. Because belt 2 10 is sleeved outside gear 2 13 and gear 3 14 at the rear, its front and rear parts move in opposite directions. The rear end of lever 1 is fixed to the front part of belt 2 10, and the rear end of lever 2 is fixed to the rear part of belt 2 10. Belt 2 10 drives shift fork 1 5 and shift fork 2 6 to swing around the limit axis at the front end so that the rear ends of the two are close to each other, thereby collecting the rear end of the garbage bag.

[0032] At the same time, driven by belts 1 9 and 3 11, push rod 7 moves horizontally backward, pushing the front of the garbage bag backward and closing it along the inclined forks 1 5 and 2 6 until push rod 7 reaches the heated cut-off member 3, whereupon the bag opening folds and closes. After push rod 7 abuts the heated cut-off member 3, the control circuit board, after the packaged driver 4 reaches the blocking current for 2 seconds, heats the heating wire and energizes it for 10 seconds, thus cutting the garbage bag and forming a seal above and below the cut-off position.

[0033] After the garbage bag is sealed, the sealing drive 4 reverses, driving the push rod 7, shift fork 1 5, and shift fork 2 6 to reset. The second drive 17 then flips the middle cover 21 upward, allowing the user to remove the garbage bag. After the garbage bag is removed, the middle cover 21 resets, and the fan 18 operates, drawing air outward, creating a negative pressure at the bottom of the barrel 1. This draws the sealed garbage bag downward from the bottom of the accommodating chamber 21a, completing the automatic bagging process.

[0034] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
