Description

Technical Field

[0001] The invention relates to the technical field of trash cans, in particular to an automatic bagging trash can. Background Art

[0002] At present, the common trash cans on the market are generally single barrel-shaped. The ones with slightly higher intelligence are induction flaps, but they all require manual picking up of the trash bag, manually stretching the trash bag, and then putting it into the trash can. In this process, first of all, in order to facilitate taking, the trash bags in residents' homes will be fixed in one place, but the trash cans will be placed in each house space, such as the living room, kitchen, bedroom, bathroom, study, etc., which requires users to find the trash bags before changing the bags, which is a very inconvenient user experience. Or a roll of trash bags is placed near each trash can for easy replacement, but the problem is that the frequency of garbage placement in each space is different. For example, in the kitchen and study, the former may need to replace the trash bag every day, while the latter may replace the trash bag once a week. In this way, placing a roll of trash bags alone in a space with a low replacement frequency brings about the problem of storage distinction. Secondly, especially in the bathroom and kitchen, there will be stains on the body of the trash can. When you bend over to replace the trash bag, there will be an unpleasant smell and it is very unhygienic. Finally, when the "Waste Classification Management Regulations" comes into effect, users will consider purchasing more trash cans to assist in classification, and then the above-mentioned problems will be highlighted. Summary of the invention

[0003] In order to solve the problems in the background technology, the present invention provides an automatic bagging trash can.

[0004] An automatic bagging trash can comprises a trash can body and a trash delivery port located at the upper part of the trash can body, wherein:

[0005] The trash can further comprises a bagging assembly, which is arranged at the upper part of the barrel body, and comprises a driving unit, a transmission unit associated with the action of the driving unit, a grabbing unit associated with the action of the transmission unit for grabbing a trash bag, and a mounting frame, wherein the inner wall of the mounting frame defines the trash delivery port, and the driving unit and the transmission unit are arranged on the outer wall of the mounting frame;

[0006] The grabbing unit moves in a horizontal direction to grab a first side of the garbage bag and pulls the first side of the garbage bag to move synchronously, and the second side of the garbage bag is fixed, thereby opening the garbage bag.

[0007] The advantage is that, through the setting of the bag-covering assembly, when there is no garbage bag in the garbage bin, automatic bag-covering can be achieved through the bag-covering assembly, freeing both hands and simplifying the bag-covering steps; the garbage bag is grasped by the grabbing unit in the horizontal direction with one side of the garbage bag and the other side of the garbage bag is fixed, so that the mouth of the garbage bag is opened in the horizontal direction, reducing the stroke of the grabbing unit when the mouth of the garbage bag is opened, improving the reliability of opening the garbage bag, and reducing energy consumption; and this structure reduces the structural complexity, thereby reducing costs; in addition, it should be added that the transmission unit and the drive unit are installed on the outer wall of the mounting frame, so that the transmission unit and the drive unit will not produce structural interference with components such as the garbage bag, and the structure is more stable and reliable.

[0008] Preferably, the trash can further comprises a trash bag assembly, a first side of the trash bag is movably connected to the trash bag assembly, and a second side of the trash bag is fixedly connected to the trash bag assembly.

[0009] The advantage is that the garbage bag is connected and fixed to the barrel body itself through the garbage bag assembly, the structure is simple, and the operation is convenient.

[0010] Preferably, the garbage bag assembly is arranged opposite to the grabbing unit.

[0011] The advantage is that garbage bags are generally made of lightweight materials. This arrangement ensures that the first side of the garbage bag is evenly stressed during the bag opening process, so that the grabbing unit can be reliably connected to the first side of the garbage bag and the mouth of the garbage bag can be opened evenly; the stroke of the grabbing unit is reduced, thereby reducing energy consumption and costs.

[0012] Preferably, the garbage bag assembly is arranged on the inner wall of the mounting frame.

[0013] The advantage is that the space of the installation frame is fully utilized, the stroke of the grabbing unit is reduced, and energy consumption and costs are reduced.

[0014] Preferably, the length from the end of the first side to the bottom of the garbage bag is shorter than the length from the end of the second side to the bottom of the garbage bag.

[0015] The advantage is that it ensures that the second side of the garbage bag can be fixed at a sufficient distance, so that the second side of the garbage bag is reliably fixed, and prevents the second side of the garbage bag from moving and falling due to unreliable fixation during the bagging process, thereby preventing the bagging failure; such a setting in this patent can ensure successful bagging.

[0016] Preferably, the end of the first side is lower than the end of the second side.

[0017] The advantage is that it ensures that the second side of the garbage bag can be fixed at a sufficient distance, so that the second side of the garbage bag is reliably fixed, and prevents the second side of the garbage bag from moving and falling due to unreliable fixation during the bagging process, thereby preventing the bagging failure; such a setting in this patent can ensure successful bagging.

[0018] Preferably, the grabbing unit comprises a grabbing piece, and the first side of the garbage bag is provided with a through hole cooperating with the grabbing piece.

[0019] The advantage is that the grabbing part and the garbage bag cooperate reliably, ensuring that the bag is in place, making the garbage bag not easy to fall off during the synchronous movement with the grabbing part, improving the success rate of bagging, and preventing the garbage bag from falling off during the synchronous movement with the grabbing part, resulting in bagging failure.

[0020] Preferably, the grabbing member is at a first angle when extending into the through hole, and the opening angle of the grabbing member changes to a second angle after grabbing the garbage bag, and the first angle is greater than the second angle.

[0021] The advantage is that the first side of the garbage bag is hooked by the grabbing member after the grabbing member is inserted into the through hole, so that the grabbing member and the garbage bag cooperate reliably and the garbage bag will not fall off while following the synchronous movement of the grabbing member, thus ensuring successful bagging.

[0022] Preferably, the gripping unit comprises a gripping member for hooking the garbage bag and / or adhesive for sticking the garbage bag.

[0023] Preferably, the bagging assembly further comprises a guide rod, the guide rod is arranged in parallel with the transmission unit, the guide rod and the transmission unit are symmetrically arranged on both sides of the mounting frame, and the grabbing unit moves along the guide rod and the transmission unit;

[0024] Alternatively, the bagging assembly further comprises a guide rod, the guide rod is arranged in parallel with the transmission unit, the guide rod and the transmission unit are symmetrically arranged on both sides of the mounting frame, and the grabbing unit moves along the guide rod and the transmission unit.

DETAILED DESCRIPTION

[0050] The content of the present invention is described in detail below with reference to the accompanying drawings.

[0051] Embodiment 1:

[0052] like Figures 1 to 22As shown, an automatic bagging trash can comprises a trash can body 1, a trash inlet 2 located at the upper part of the trash can body 1, wherein the trash can further comprises a bagging assembly 3, the bagging assembly 3 is arranged at the upper part of the trash can body 1, the bagging assembly 3 comprises a driving unit 4, a transmission unit 5 associated with the action of the driving unit 4, a grabbing unit 6 associated with the action of the transmission unit 5 for grabbing a trash bag 8, and a mounting frame 7, the inner wall of the mounting frame 7 defines the trash inlet 2, and the driving unit 4 and the transmission unit 5 are arranged on the outer wall of the mounting frame 7;

[0053] The grabbing unit 6 moves in a horizontal direction to grab the first side 803 of the garbage bag 8 and pulls the first side 803 of the garbage bag 8 to move synchronously, and the second side 804 of the garbage bag 8 is fixed, thereby opening the garbage bag 8.

[0054] The advantage is that, through the setting of the bagging assembly 3, when there is no garbage bag 8 in the garbage bin, automatic bagging can be achieved through the bagging assembly 3, freeing both hands and simplifying the bagging steps; the garbage bag 8 is grabbed by the grabbing unit 6 in the horizontal direction with one side of the garbage bag 8 and the other side of the garbage bag 8 is fixed, so that the mouth 802 of the garbage bag 8 is opened in the horizontal direction, and the stroke of the grabbing unit 6 when the mouth 802 of the garbage bag 8 is opened is reduced, the reliability of opening the garbage bag 8 is improved, and energy consumption can be reduced; and this structure reduces the structural complexity, thereby reducing the cost; in addition, it should be added that the transmission unit 5 and the drive unit 4 are installed on the outer wall of the mounting frame 7, so that the transmission unit 5 and the drive unit 4 will not produce structural interference with the garbage bag 8 and other components, and the structure is more stable and reliable.

[0055] The barrel body 1 is provided with a button 10, and the user can control the bagging assembly 3 to realize automatic bagging through the button 10. The advantage of this method is low cost. It can be understood that the trash can can also include a detection unit for detecting whether there is a trash bag 8, by detecting whether there is a trash bag 8 and transmitting the detection signal to the circuit board 16, the circuit board 16 controls the driving unit 4 to work, thereby realizing automatic bagging. The advantage of this method is that it is more intelligent.

[0056] like Figures 2 to 5 As shown, the inner wall of the mounting frame 7 is the inner wall of the mounting frame 7 facing the inside of the barrel body 1, and the outer wall of the mounting frame 7 is the wall except the side wall of the mounting frame 7 facing the inside of the barrel body 1, such as the upper wall, lower wall, and outer wall of the mounting frame 7 facing away from the inside of the barrel body 1.

[0057] like Figure 5As shown, the trash can also includes a power supply unit for supplying power to the drive unit 4, the power supply unit is electrically connected to the drive unit 4, and the power supply unit includes a battery and a battery compartment 15, the battery is a replaceable disposable battery (an ordinary battery that is discarded after use) or a reusable rechargeable battery. The battery compartment 15 is arranged on the mounting frame 7, and preferably the battery compartment is arranged on the outer wall of the mounting frame 7. Since the trash can in this example uses ordinary batteries or rechargeable batteries, the trash can can be moved anywhere most of the time, and can be placed in different spaces as needed, such as a kitchen, bedroom, living room or bathroom.

[0058] As another example, the trash can may not have its own power supply unit. The power supply unit is a power supply module outside the trash can. For example, a power cord is plugged into a socket, and the power cord is electrically connected to the drive unit 4, and the drive unit 4 is powered by the power grid; or the drive unit 4 is powered by wireless power supply.

[0059] The power supply unit referred to in the present invention refers to a component that can provide electrical energy to the driving unit 4 .

[0060] like Figures 1 to 5 The driving unit 4 includes a motor 401 and a reduction gear assembly 402, and the transmission unit 5 includes a synchronous belt 501, a fixing member 506, a first synchronous gear 507 and a second synchronous gear 508. The first synchronous gear 507 and the second synchronous gear 508 are respectively located at both ends of the synchronous belt 501. The synchronous belt 501 is wound around the first synchronous gear 507 and the second synchronous gear 508, and the synchronous belt 501 is provided with saw teeth that match the first synchronous gear 507 and the second synchronous gear 508. The first synchronous gear 507 is connected to the fixing member 501, and the fixing member 506 is arranged on the mounting frame 7. The output shaft of the motor 401 transmits power to the reduction gear assembly 402, driving the reduction gear assembly 402 to rotate, and the reduction gear assembly 402 transmits power to the second synchronous gear 508. The rotation of the second synchronous gear 508 drives the synchronous belt 501 and the first synchronous gear 501 to rotate. The driving unit 4 has two groups, each group includes the components described above, and the transmission unit 5 also has two groups, and the two groups of transmission units 5 are respectively arranged on both sides of the mounting frame 7, and each group includes the components described above. The driving unit 4 and the transmission unit 5 are arranged on the outer side wall of the mounting frame 7 facing away from the inside of the barrel body 1, and the driving unit 4 and the transmission unit 5 are perpendicular to each other in the mounting direction. The bagging assembly 3 also includes a guide rod 11, and the guide rod 11 is arranged in parallel with the transmission unit 5. The guide rod 11 and the transmission unit 5 are symmetrically arranged on both sides of the mounting frame 7, and the grabbing unit 6 moves along the guide rod 11 and the transmission unit 5. There are two guide rods 11, and the two guide rods 11 are respectively arranged above the two synchronous belts 501. The grabbing unit 6 is perpendicular to the guide rod 11 and the synchronous belt 501. When the synchronous belt 501 rotates, the grabbing unit 6 moves in the horizontal direction.

[0061] like Figures 2 to 4 , Figure 6 As shown, the grabbing unit 6 includes a rod portion 601, a sleeve 604 cooperating with the guide rod 11, and a matching portion 605 cooperating with the synchronous belt 501. Due to the limitations of the transmission method and the number of guide rods 11 in this example, the sleeve 604 has two and is respectively arranged on both sides of the rod portion 601, and the matching portion 605 has two and is respectively arranged on both sides of the rod portion 601.

[0062] like Figures 6 to 9 As shown, the grabbing unit 6 includes a grabbing member 602 , which is connected to the rod 601 . The first side 803 of the garbage bag 8 is provided with a through hole 807 that cooperates with the grabbing member 602 . The grabbing member 602 extends into the through hole 807 so that the garbage bag 8 can be hung on the grabbing member 602 . The grabbing member 602 can cooperate with the garbage bag 8 reliably to ensure that the bag is in place, so that the garbage bag 8 is not easy to fall off during the synchronous movement with the grabbing member 602, thereby improving the success rate of bagging and preventing the garbage bag 8 from falling off during the synchronous movement with the grabbing member 602 and causing bagging failure; the garbage bag 8 is generally made of lightweight materials. Due to the influence of static electricity, friction, and manufacturing process, the mouth 802 of the garbage bag 8 is not easy to open. When using gloves to pick up the garbage bag 8, it is necessary to rub the mouth 802 with fingers before it is easier to open. Through the setting of the grabbing member 602 and the through hole 807, the grabbing member 602 can apply external force to the garbage bag 8, so that the mouth 802 of the garbage bag 8 is easier to open.

[0063] The grabbing unit 6 includes a grabbing member 602 for hooking the garbage bag 8; or includes a glue 603 for sticking the garbage bag 8; or includes a grabbing member 602 and a glue 603. In order to make the automatic bagging more reliable, the grabbing unit 6 in this example includes a grabbing member 602 for hooking the garbage bag 8 and a glue 603, and the glue 603 sticks to the first side 803 of the garbage bag 8. The glue 603 is waterproof and highly viscous, and has high viscosity even after repeated washing, ensuring that the garbage bag 8 is firmly bonded. During daily use, the glue 603 may be dirty. If the bonding effect is not ideal after washing, the user can replace it with a new glue 603. Through the cooperation of the glue 603 and the grabbing member 602, the garbage bag 8 is prevented from falling off and bagging failure caused by the weakening of the viscosity of the glue 603.

[0064] In the above scheme, the adhesive 603 is the preferred scheme, but is not limited to other ways of grabbing the garbage bag 8, such as a rotating roller with a certain friction on the surface, a sticky PU block, and suction using an air pump.

[0065] like Figures 7 to 9As shown, the opening angle of the gripping member 602 is adjustable. The advantage is that by adjusting the opening angle of the gripping member 602, the fit between the garbage bag 8 and the gripping member 602 can be improved during the bagging process, preventing the garbage bag 8 from falling and causing bagging failure; when the garbage bag 8 is full, it is convenient for the user to take the garbage bag 8 off the gripping member 602.

[0066] like Figure 8 , Fig. 9 As shown, the grabbing member 602 is at a first angle when it extends into the through hole 807, and the opening angle of the grabbing member 602 changes to a second angle after grabbing the garbage bag 8, and the first angle is greater than the second angle. The advantage is that after the grabbing member 602 extends into the through hole 807, the first edge 803 of the garbage bag 8 is hooked by the grabbing member 602, so that the grabbing member 602 and the garbage bag 8 are reliably matched, so that the garbage bag 8 will not fall off in the process of following the grabbing member 602 to move synchronously, and the bagging is ensured to be successful.

[0067] Further, such as Figures 7 to 10 As shown, the gripping unit 6 further comprises a switching unit 13 for changing the opening angle of the gripping member 602, and the switching unit 13 is connected to the gripping member 602. The advantage is that, through the setting of the switching unit 13, the gripping member 602 can automatically switch the opening angle, which has a simple structure and is easy to implement.

[0068] The angle of the gripping member 602 can be achieved simply through a mechanical structure, or through a combination of an electric control element and a mechanical structure. When the angle of the gripping member is adjustable through the cooperation of an electric control element and a mechanical structure, the specific method is to use an electric control element to determine whether the gripping member 602 is in place, and the gripping member 602 is driven by a micro motor. When the gripping member 602 is in place, the opening angle of the gripping member 602 is driven by the micro motor. The above-mentioned switching unit 13 can be the micro motor, or the switching unit can be a mechanical structure directly or indirectly connected to the gripping member 602, and the mechanical structure can be one or more components. In this example, in order to save costs, the angle adjustment of the gripping member 602 is achieved simply through mechanical means.

[0069] Furthermore, the bagging assembly 3 further comprises a mounting frame 7 for mounting the grabbing unit 6, and a switching member 14 cooperating with the switching unit 13 is provided on the mounting frame 7, and the switching unit 13 cooperates with the switching member 14 to change the opening angle of the grabbing member 602. The advantage is that, through the cooperation between the switching unit 13 and the switching member 14, the grabbing member 602 can realize the change of the opening angle of the grabbing member 602 during its movement stroke.

[0070] The switching member 14 includes a switching slope 1401 and a maintaining plane 1402. The height of the switching slope 1401 gradually increases in the direction close to the garbage bag 8. The second end of the switching slope 1401 is higher than the first end. One end of the maintaining plane 1402 is connected to the second end of the switching slope 1401. The advantages are simple structure, easy implementation and low cost. The grabbing unit 6 also includes a rod 601, the switching unit 13 includes a push plate 1301, a connecting rod 1302 connecting the push plate 1301 and the grabbing member 602, and a torsion spring 1303 sleeved on the connecting rod 1302, the grabbing member 602 is arranged on a first side 803 of the rod 601 opposite to the garbage bag 8, the switching unit 13 is arranged on a second side 804 opposite to the first side 803, the torsion spring 1303 abuts against the rod 601, the push plate 1301 and the switching inclined surface 1401 cooperate to compress the torsion spring 1303 to rotate the connecting rod 1302 and then drive the grabbing member 602 to rotate, thereby changing the opening angle of the grabbing member 602. The advantage is that the structure is simple, easy to implement, and low cost. The grabbing unit 6 moves in the horizontal direction. Before the push plate 1301 reaches the switching member 14, the grabbing member 602 is at the second angle. The push plate 1301 contacts the first end of the switching slope. As the grabbing unit 6 gradually moves in the horizontal direction, the opening angle of the grabbing member 602 gradually increases under the cooperation of the push plate 1302, the torsion spring 1303, and the switching slope 1401. When the push plate 1301 reaches the second end, the opening angle of the grabbing member 602 is the first angle. The grabbing unit 6 continues to move in the horizontal direction. The push plate 1302 cooperates with the maintaining plane 1402 to maintain the opening angle of the grabbing member 602 at the first angle until the grabbing member 602 grabs the first side 803 of the garbage bag 8. After grabbing the garbage bag, the circuit board 16 controls the motor 401 to reverse the garbage bag 8 and move with the grabbing unit 6 to open the bag. During the bag opening process, the push plate 1302 first cooperates with the maintaining plane 1402 to maintain the opening angle of the grabbing member 602 at the first angle until the second end of the switching slope 1401, and then as the grabbing unit 6 continues to move horizontally, the push plate 1302, the torsion spring 1303, and the switching slope 1401 cooperate to make the opening angle of the grabbing member 602 gradually decrease. When the push plate 1302 reaches the second end of the switching slope 1401, the opening angle of the grabbing member 602 becomes the second angle, and then the opening angle of the grabbing member 602 maintains the second angle until the bag opening is completed.

[0071] It can be understood that the switching member 14 is a switching slope 1401 (this embodiment is not shown in the figure), the height of the switching slope 1401 gradually increases in the direction close to the garbage bag 8, the second end of the switching slope 1401 is higher than the first end, the grabbing unit 6 also includes a rod 601, the switching unit 13 includes a push plate 1301, a connecting rod 1302 connecting the push plate 1301 and the grabbing member 602, and a torsion spring 1303 sleeved on the connecting rod 1302, the grabbing member 602 is arranged on a first side 803 of the rod 601 opposite to the garbage bag 8, the switching unit 13 is arranged on a second side 804 opposite to the first side 803, the torsion spring 1303 abuts against the rod 601, the push plate 1301 and the switching slope 1401 cooperate to compress the torsion spring 1303 to rotate the connecting rod 1302 and then drive the grabbing member 602 to rotate, thereby changing the opening angle of the grabbing member 602. The grabbing unit 6 moves in the horizontal direction. Before the push plate 1301 reaches the switching member 14, the grabbing member 602 is at the second angle. The push plate 1301 contacts the first end of the switching slope. As the grabbing unit 6 gradually moves in the horizontal direction, the opening angle of the grabbing member 602 gradually increases under the cooperation of the push plate 1302, the torsion spring 1303 and the switching slope 1401. When the push plate 1301 reaches the second end, the opening angle of the grabbing member 602 is the first angle. At this time, the grabbing member 602 grabs the garbage bag. 8, after grabbing the garbage bag, the circuit board 16 controls the motor 401 to reverse the garbage bag 8 and follow the grabbing unit 6 to open the bag. During the bag opening process, with the cooperation of the push plate 1302, the torsion spring 1303 and the switching slope 1401, the opening angle of the grabbing member 602 gradually decreases. When the push plate 1302 reaches the second end of the switching slope 1401, the opening angle of the grabbing member 602 becomes the second angle, and then the opening angle of the grabbing member 602 maintains the second angle until the bag opening is completed.

[0072] The garbage bag 8 includes a movable first side 803 and a fixed second side 804, and the through hole 807 is arranged on the first side 803. The advantage is that the first side 803 of the garbage bag 8 is not subjected to force, so that the gripping member 602 can open the mouth 802 of the garbage bag 8 with less force, reducing the structural difficulty and making the bag opening reliable.

[0073] like Figure 2 , 8As shown in 11 to 13, the garbage bag 8 in this example includes a bag body 801, and the upper part of the bag body 801 has an opening 802 for allowing external objects to enter the bag body 801, wherein the bag body 801 includes a first side 803 and a second side 804 opposite to each other, and the length from the end of the first side 803 to the bottom of the garbage bag 8 is shorter than the length from the end of the second side 804 to the bottom of the garbage bag 8. Ensure that the second side 804 of the garbage bag 8 can be fixed at a sufficient distance, so that the second side 804 of the garbage bag 8 is reliably fixed, and prevent the second side 804 of the garbage bag 8 from falling due to unreliable fixation during the bagging process, thereby preventing the bagging from failing; such a setting in this patent can ensure successful bagging.

[0074] Furthermore, the end of the first side 803 and the end of the second side 804 have a height difference, that is, the end of the first side 803 is lower than the end of the second side 804. The advantage is that the easiness of opening the mouth of the garbage bag 8 is improved. Since the garbage bag 8 is generally made of lightweight materials, the first side 803 and the second side 804 of the garbage bag 8 are attracted together by friction and static electricity. The ends of the first side 803 and the second side 804 of the ordinary garbage bag 8 are flush, and the garbage bag 8 needs to be rubbed by hand to open it. Especially for the breakpoint and scroll-type garbage bags 8, the garbage bag 8 is rectangular, and the ends of the first side 803 and the second side 804 are flush. Sometimes it is necessary to find the mouth 802 of the garbage bag 8. In the present invention, the upper end of the first side 803 and the upper end of the second side 804 have a height difference, and the mouth 802 can be observed by naked eyes, the target is clearer, and the steps of opening the mouth 802 of the garbage bag 8 are reduced. Ensure that the second side 804 of the garbage bag 8 can be fixed at a sufficient distance, so that the second side 804 of the garbage bag 8 is fixed reliably, and prevent the second side 804 of the garbage bag 8 from moving and falling due to unreliable fixation during the bagging process, thereby preventing the bagging from failing; such a setting in this patent can ensure successful bagging and make the garbage belt easier to open. In this example, the end of the first side 803 refers to the end close to the garbage bag 8 near the mouth 802.

[0075] Furthermore, a through hole 807 is provided on the first side 803 near its end, and there are two through holes 807 which are symmetrically arranged.

[0076] Furthermore, a through hole 808 is provided on the second side 804 near its end, and there are two through holes 808 which are symmetrically arranged.

[0077] Furthermore, the garbage bag is provided with a handle 809 , which has two handles and is respectively provided on the first side 803 and the second side 804 , two through holes 807 are provided on both sides of the handle 809 , and two through holes 808 are provided on both sides of the handle 809 .

[0078] Further, in this example, the middle of the first side 803 has a first convex portion 805 extending upward, the middle of the second side 804 has a second convex portion 806 extending upward, and the height of the first convex portion 805 is less than the height of the second convex portion 806. The first convex portion 805 is provided with a through hole 807. There are two through holes 807, which are respectively arranged on both sides of the first convex portion 805. The second convex portion 806 is provided with a through hole 808. There are two through holes 808, which are respectively arranged on both sides of the second convex portion 806. The extension starting point heights of the first convex portion 805 and the second convex portion 806 are the same.

[0079] It can be understood that the first side 803 is provided with a first protrusion 805 extending upward from the end thereof; the end of the second side 804 is flush. The first protrusion 805 is provided with a through hole 807. There are two through holes 807, which are respectively arranged on both sides of the first protrusion 805. The second side 804 is provided with a through hole 808, and further, there are two through holes 808, which are symmetrically arranged.

[0080] It can be understood that the second side 804 is provided with a second protrusion 806 extending upward from its end; the end of the first side 803 is flush. The first side 803 is provided with a through hole 807, and the through holes 807 are provided in two and symmetrically arranged. The second protrusion 806 is provided with a through hole 808. The through holes 808 are provided in two and are respectively arranged on both sides of the second protrusion 806.

[0081] like Figure 1 , 2 As shown in 6 to 22, the trash can also includes a trash bag assembly 9, the first side 803 of the trash bag 8 is movably connected to the trash bag assembly 9, and the second side 804 of the trash bag 8 is fixedly connected to the trash bag assembly 9. The trash bag 8 is connected and fixed to the barrel body 1 itself through the trash bag assembly 9, which has a simple structure and is easy to operate. There are multiple trash bags 8, and multiple trash bags 8 are stacked together. Each trash bag 8 has a first side 803 and a second side 804. The first side 803 of each trash bag 8 is movably connected to the trash bag assembly 9, and the second side 804 of each trash bag 8 is fixedly connected to the trash bag assembly 9. The movable connection referred to in this example can be that relative displacement can be generated between two different parts, and the fixed connection means that the two parts are connected together without applying external force, and the two parts can still be separated after applying external force. Specifically, as is well known, the trash bag 8 is generally made of lightweight materials. After the second side 804 of the trash bag 8 is clamped by the trash bag assembly 9, after the trash bag 8 is full, the second side 804 can still be separated from the trash bag assembly 9 after applying external force to the second side 804. More specifically, the first shell 901 and the second shell 902 cooperate to clamp the second edge 804, and the first edge 803 is suspended in the air. The advantage is that it is easy to open the garbage bag 8.

[0082] The garbage bag assembly 9 is provided with an extension piece 904 that cooperates with the through hole 807. When the grabbing piece 602 extends into the through hole 807, the grabbing piece 602 is located in the extension piece 904. The advantage is that the first side 803 of the garbage bag 8 is hung on the extension piece 904 through the cooperation between the through hole 807 and the extension piece 904, thereby realizing the movable connection between the first side 803 of the garbage bag 8 and the garbage bag assembly 9, so that the garbage bags 8 are neatly arranged, and the cooperation between the grabbing piece 602 and the garbage bag 8 is also convenient, so that one bag can be put on at a time. In this example, the extension piece 804 is composed of two extension plates, which are arranged opposite to each other and form a channel 911 for the grabbing piece 602 to at least partially extend into.

[0083] In this example, if Figure 1 , 2 As shown in 6, 11 to 13, the grabbing unit 6 includes a rod 601, which is arranged opposite to the garbage bag assembly 9, and is perpendicular to the guide rod 11 and the synchronous belt 501. The side of the rod 601 facing the garbage bag assembly 9 is provided with a grabbing member 602 and an adhesive 603. When the rod 601 moves to the place where the garbage bag assembly 9 is placed, the adhesive 603 sticks to the first side 803 of the garbage bag 8, and the grabbing member 602 hooks the first side 803 of the garbage bag 8. Then, the program controls the motor 401 to reverse, the first side 803 of the garbage bag 8 is grabbed and moves with the rod 601, and the second side 804 of the garbage bag 8 is clamped by the first shell 901 and the second shell 902, and the mouth 802 of the garbage bag 8 will be slowly opened until the rod 601 moves to the starting position, the motor 401 stops power output, and the entire bagging action is completed.

[0084] The garbage bag assembly 9 is arranged opposite to the grabbing unit 6. The garbage bag 8 is generally made of a lightweight material, and such an arrangement allows the first side 803 of the garbage bag 8 to be evenly stressed during the bag opening process, so that the grabbing unit 6 can be reliably connected to the first side 803 of the garbage bag 8, and the mouth 802 of the garbage bag 8 can be evenly opened; the stroke of the grabbing unit 6 is reduced, and energy consumption and costs are reduced.

[0085] Furthermore, the bagging assembly 3 also includes a garbage bag assembly 9, one end of the garbage bag 8 is connected to the garbage bag assembly 9, and the other end of the garbage bag 8 is suspended. The advantage is that the garbage bag assembly 9 is provided to facilitate the replacement of the garbage bag 8, and one end of the garbage bag 8 is suspended, so that the bagging process can be completed with minimal steps, reducing energy consumption, simplifying the structure, and reducing costs; by including the garbage bag assembly 9 in the kit assembly, the structure of the barrel 1 can be simplified, and it is more convenient to clean part of the barrel 1. The garbage bag assembly 9 is arranged on the inner wall of the mounting frame 7. Make full use of the space of the mounting frame 7, reduce the stroke of the grabbing unit 6, and reduce energy consumption and cost. Furthermore, the side wall of the mounting frame 7 forms a concave cavity 701 outwardly, and the garbage and the assembly are arranged in the concave cavity 701.

[0086] like Figures 14 to 21 As shown, the garbage bag assembly 9 includes a first shell 901 and a second shell 902, wherein the first shell 901 and the second shell 902 cooperate to clamp one end of the garbage bag 8, and the other end of the garbage bag 8 is suspended. The advantages are that the structure is simple, the cost is low, and it is easy to replace the garbage bag 8. More specifically, the clamped end of the garbage bag 8 is the end close to the mouth 802, and the suspended other end is or is close to the bottom of the garbage bag 8.

[0087] like Figures 14 to 16 As shown, an example of a garbage bag assembly 9, the first shell 901 and the second shell 902 are matched left and right, and the first edge 803 is located on the side of the first shell 901 away from the second shell 902. When the garbage bag assembly 9 is assembled in a garbage can, the first shell 901 is close to the axis of the garbage can, and the second shell 902 is far away from the axis of the garbage can.

[0088] Further, such as Figures 11 to 13 , Fig.17 As shown, the first shell 901 is provided with a mounting shaft 903 on one side opposite to the second shell 902, and the second side 804 is provided with a through hole 808 that matches the mounting shaft 903, and the mounting shaft 903 passes through the through hole 808; the advantage is that the assembly reliability of the garbage bag 8 and the garbage belt assembly is improved. It can be understood that the second shell 902 is provided with a mounting shaft 903 on one side opposite to the first shell 901, and the second side 804 is provided with a through hole 808 that matches the mounting shaft 903, and the mounting shaft 903 passes through the through hole 808. The advantage is that the assembly reliability of the garbage bag 8 and the garbage belt assembly is improved.

[0089] Further, such as Figures 11 to 13 , Fig.16As shown, a through hole 807 is provided on the first side 803, and an extension piece 904 matching with the through hole 807 is provided on the side of the first shell 901 away from the second shell 902, and the extension piece 904 passes through the through hole 807. The second side 804 of the garbage bag 8 is neatly stacked on the garbage bag assembly 9, which is tidy and convenient for next use.

[0090] Further, such as Fig.15 , 16 As shown, an opening 905 is provided on one side of the first shell 901 opposite to the second shell 902, and the second side 804 is folded through the opening 905. The advantage is that the garbage bag 8 and the garbage bag assembly 9 are fixed reliably, and the second side 804 can be pulled out with a little force, so that the user can remove the second side 804 from the garbage bag 8 from the garbage belt assembly after the garbage bag 8 is full. The opening 905 can be a gap between the upper end of the first shell 901 and the second shell 902, or it can be a hole on the first shell 901, and the opening is a certain distance from the upper end and the lower end of the first shell 901.

[0091] Further, such as Fig.14 , 15 As shown in Figures 18, the second shell 902 includes a bent portion 906, which extends toward the first shell 901 and covers the opening 905. The advantage is that the bent portion 906 presses the second side 804 of the garbage bag 8, so that the garbage bag 8 and the garbage bag assembly 9 are reliably fixed; on the other hand, the bent portion 906 blocks part of the joint gap between the first shell 901 and the second shell 902, making the appearance more concise, and reducing the gaps on the surface of the garbage bag assembly 9, which can reduce the accumulation of dust and dirt, making it cleaner and more hygienic.

[0092] like Figures 19 to 21 As shown, another example of the garbage bag assembly 9, the first shell 901 and the second shell 902 cooperate with each other to form a U-shaped clamp or a "7"-shaped clamp on the second side 804. The first shell 901 is located above the second shell 902, the second shell 902 is U-shaped, and the first shell 901 is E-shaped. The middle part of the first shell 901 has a convex rib 907 extending downward, and the convex rib 907 and the side wall of the second shell 902 form a slot 908. The second side 804 of the garbage bag 8 is partly in the slot 908, so that the second side 804 of the garbage bag 8 near the end of the second side 804 is U-shaped, thereby forming a U-shaped clamp of the garbage bag assembly 9 on the garbage bag 8. The second shell 902 is provided with a draw-out opening 910, and the second side 804 can be drawn out with a little force. The extraction opening 910 may be a gap between the upper end of the first shell 901 and the second shell 902 , or may be a hole provided on the first shell 901 , which is at a certain distance from the upper end and the lower end of the first shell 901 .

[0093] like Figure 2 , 5 , 7, 8, 9, 14, and 19, as in the above two examples of garbage bags 8, the second shell 902 is provided with limiting grooves 909 on both sides, and the barrel body 1 or the mounting frame 7 is provided with limiting ribs 12. The garbage bag assembly 9 is installed on the barrel body 1 or the mounting frame 7 from top to bottom through the cooperation of the limiting grooves 909 and the limiting ribs 12. The limiting grooves 909 and the limiting ribs 12 are designed to be interference fit to achieve the goal of limiting the position of the garbage bag assembly 9. The preferred method described here is to realize the assembly of the garbage bag assembly 9 with the garbage can. It can be understood that the positions of the limiting grooves 909 and the limiting ribs 12 can be interchanged, that is, the limiting ribs 12 are set on the second shell 902, and the limiting grooves 909 are set on the barrel body 1 or the mounting frame 7.

[0094] Further, such as Fig. 22 As shown, a partition 17 is provided in the barrel body 1, and the garbage bag 8 is located between the partition 17 and the side wall of the barrel body 1. The advantage is that the expanded garbage bag 8 is separated from the opened garbage bag 8, preventing sharp objects in the expanded garbage bag 8 from puncturing the unused garbage bag 8, while taking into account the storage function of the garbage bag 8, so that the garbage bag 8 can be neatly placed in the barrel body 1.
