Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment is as follows:

as shown in fig. 1 to 14, an automatic bagging garbage can comprises a can body 1, a garbage input opening 110 located at the upper part of the can body 1, and a bagging assembly 2, wherein the bagging assembly 2 is arranged at the upper part of the can body 1, the bagging assembly 2 comprises a driving unit 210, a transmission unit 220 operatively associated with the driving unit 210, a grabbing unit 230 operatively associated with the transmission unit 220 for grabbing a garbage bag 3, and a mounting frame 240, and the inner wall of the mounting frame 240 defines the garbage input opening 110; the grabbing unit 230 moves in the horizontal direction to grab the first edge 310 of the garbage bag 3 and pull the first edge 310 of the garbage bag 3 to move synchronously, and the second edge 320 of the garbage bag 3 is fixed, so that the garbage bag 3 is opened; the transmission unit 220 includes a link transmission mechanism, and the motion of the grasping unit 230 in the horizontal direction is associated with the motion of the link transmission mechanism in the vertical direction.

As shown in fig. 1, the can body 1 is a main body of the trash can, the trash input opening 110 is an opening for limiting the garbage input, and the trash input opening 110 is formed at an upper end of the can body 1, and similarly, the trash input opening 110 may be formed at a side wall of the can body 1 as long as the trash can be input into the trash can through the trash input opening 110.

As shown in fig. 1, the bagging assembly 2 is a device for expanding the garbage bag 3 to be sleeved on the upper portion of the can body 1, because the garbage input opening 110 is formed in the upper portion of the can body 1, the bagging assembly 2 is arranged on the upper portion of the can body 1, so that the bag opening of the garbage bag 3 can be better expanded to be sleeved on the garbage input opening 110, wherein the driving unit 210 is a device for driving the bagging assembly 2 to complete a bagging action, such as a motor and the like, which can output power.

As shown in fig. 1, 2, 4 and 5, wherein the driving unit 210 drives the transmission unit 220 to move, and then the transmission unit 220 drives the grabbing unit 230 to move and grab the garbage bag 3, the garbage bag 3 includes a first edge 310 and a second edge 320, wherein the second edge 320 is defined to be immovable, and the first edge 310 is defined to be associated with the movement of the grabbing unit 230, that is, the first edge 310 is grabbed by the grabbing unit 230 to move, thereby spreading the garbage bag 3 open.

As shown in fig. 1, the mounting frame 240 is installed in the tub 1, so that the mounting frame 240 can be easily disassembled and installed, wherein the interior of the mounting frame 240 defines the garbage input port 110, the driving unit 210 and the transmission unit 220 are disposed on the outer side wall of the mounting frame 240, and the driving unit 210 and the transmission unit 220 are located between the mounting frame 240 and the inner side wall of the tub 1, which is beneficial to reasonably utilizing the space of the garbage tub on one hand and to prevent these structural members from being contaminated by the garbage on the other hand.

As shown in fig. 1 to 5, the transmission unit 220 includes a link transmission mechanism, so that the grasping unit 230 is moved by the link transmission mechanism.

As shown in fig. 1, 2, 4, and 5, the link transmission mechanism has a plurality of links, two adjacent links are connected, and the driving unit 210 provides power to the link transmission mechanism, so that the link transmission mechanism can generate displacement in both vertical and horizontal directions. The motion of the grasping unit 230 in the horizontal direction is associated with the motion of the link transmission mechanism in the vertical direction.

As shown in fig. 1, 2, 4 and 5, the grabbing unit 230 and the link transmission mechanism are arranged in a crossed manner, and the link transmission mechanism is directly connected with the grabbing unit, so that the transmission of torque is facilitated, and the loss of force is reduced.

As shown in fig. 2, 4 and 5, the link transmission mechanism is always located below the garbage input port 110 in the stroke range of the grabbing unit 230. The connecting rod transmission mechanism is always positioned below the garbage throwing-in opening 110 in the whole action process, so that the space below the garbage throwing-in opening 110 in the vertical direction is fully utilized, and the space utilization rate is improved.

Further, when the link transmission mechanism moves upwards, the grabbing unit 230 approaches the garbage bag 3; conversely, when the link transmission mechanism moves downwards, the grabbing unit 230 moves away from the garbage bag 3. In the technical scheme, the driving unit 210 is hidden and arranged opposite to the garbage bag 3, so that the weight of each part on the garbage can body 1 is reasonably distributed, the gravity center of the garbage can is positioned on or close to the axis of the garbage can, and the garbage can is placed more stably; and the garbage throwing port 110 is positioned at the middle part of the can body 1, so that a user can more accurately throw garbage into the can body 1.

The link transmission mechanism includes a driving rod 221 operatively associated with the driving unit 210, and a driven rod 222 operatively associated with the driving rod 221, wherein one end of the driven rod 222 is movably connected to the grasping unit 230, one end of the driving rod 221 is movably connected to the mounting frame 240, and the other end of the driven rod 222 is movably connected to the other end of the driving rod 221, and the movable connection means that the two components are connected but can move relative to each other.

The other end of the driven rod 222 is connected to the driving rod 221, and the driving unit 210 drives the driving rod 221 to swing around the joint of the driving rod 221 and the mounting frame 240 as an axis, so that the driving rod 221 can generate vertical displacement, and the driven rod 222 is driven to generate vertical displacement, so that one end of the driven rod 222 connected to the grabbing unit 230 makes reciprocating horizontal movement under the action of the driving rod 221. Further, since the driving link 221 and the driven link 222 constitute a link transmission mechanism, when the driving link 221 and the driven link 222 are coupled together, the driving link 221 and the driven link 222 are configured in a "V" shape therebetween.

In this example, when the link transmission mechanism moves upward, that is, the connection between the driving rod 221 and the driven rod 222 moves upward, the grabbing unit 230 moves toward the garbage bag 3 until the grabbing unit 230 stops moving to the position where the garbage bag 3 is located, the grabbing unit 230 successfully grabs the garbage bag 3, and then when the connection between the driving rod 221 and the driven rod 222 moves downward, the grabbing unit 230 moves away from the garbage bag 3, the mouth of the garbage bag 3 is opened, and automatic bagging is completed.

As shown in fig. 4, the stroke distance of the grabbing unit 230 is less than or equal to the sum of the lengths of the driving rod 221 and the driven rod 222, specifically, since the grabbing unit 230 is connected to one end of the driven rod 222, and the driven rod 222 is connected to the driving rod 221 and is driven by the driving rod 221, the stroke distance of the grabbing unit 230 should be the maximum sum of the distances of the driving rod 221 and the driven rod 222, that is, when the driving rod 221 and the driven rod 222 move to a horizontal line, the stroke distance of the grabbing unit 230 should be less than or equal to the sum of the lengths of the driving rod 221 and the driven rod 222, and in this example, the stroke distance of the grabbing unit 230 is preferably less than the sum of the lengths of the driving rod 221 and the driven rod 222.

As shown in fig. 10, in a possible state where the swing angle of the active rod 221 is α, and α is an acute angle, in a first case, in an initial state, the active rod 221 is disposed at an angle to the vertical direction, so as to facilitate the transmission of torque, and a motor with relatively low power may be selected to drive the grabbing unit 230 to move horizontally; in the second case, the link transmission mechanism is always located below the garbage input port 110 without limiting the angle between the driving lever 221 in the initial state and the vertical direction. When the angle alpha is larger than or equal to 90 degrees, the driving rod 221 and the driven rod 222 are unfolded to form a horizontal line or are protruded upwards, so that the connecting rod transmission mechanism is difficult to reset or even cannot be reset, the garbage bag 3 cannot be opened, and meanwhile, the connecting rod transmission mechanism occupies a large space, and the integral attractiveness of the garbage can is influenced; it may also cause the link transmission mechanism to be jammed and not to effectively drive the grasping unit 230 to move.

As shown in fig. 10, in the initial state, an included angle between the driving link 221 and the driven link 222 is β, and the magnitude of β is inversely proportional to the torque output by the driving unit 210. The driving unit 210 includes a motor, the larger the torque output by the motor is, the higher the price is, in the technical scheme, the smaller beta is, the larger the torque of the motor is required to be; the smaller beta, the less torque of the motor is required. Through the setting of the initial included angle β between the driving rod 221 and the driven rod 222, a proper driving unit 210 can be selected, so that reliable transmission is ensured, the situation that the grabbing unit does not move after the driving unit 210 starts to work is prevented, and meanwhile, the cost is controlled within a proper range. Furthermore, beta is more than or equal to 1 degree and less than or equal to 30 degrees, and the advantages of ensuring the reliability of transmission, ensuring the proper torque of the driving unit and ensuring the reasonable cost; when beta is less than 1 degree, a motor capable of outputting larger torque needs to be selected to ensure that the connecting rod transmission mechanism transmits force to the grabbing unit, so that the cost is increased; when beta is more than 30 degrees, a larger installation space is occupied, so that the volume of the machine is increased; or in order to miniaturize the machine, the grabbing units are arranged on the side wall of the garbage throwing port to form gaps, so that the area of the garbage throwing port is reduced.

As shown in fig. 10, the connection point of the driven rod 222 and the driving rod 221 is located between the other end of the driven rod 222 and the other end of the driving rod 221, so that the driving rod 221, the driven rod 222 and the mounting frame 240 are configured as an acute triangle, thereby ensuring reliable transmission and effectively driving the link transmission mechanism to move in the initial state. As shown in fig. 11, when the joint of the driven rod 222 and the driving rod 221 is close to the driving unit 210, when the driving rod 221 swings clockwise, the driven rod 222 cannot be driven to move, so that the link transmission mechanism is jammed and cannot drive the grabbing unit to move; as shown in fig. 12, when the connection point of the driven link 222 and the driving link 221 is close to the garbage bag 3, the other end of the driving link 221 moves in a direction close to the driving unit 210 when the driving unit 210 operates, and the link transmission mechanism cannot drive the grasping unit 230 to move.

As shown in fig. 10, when the grabbing unit 230 approaches the garbage bag 3, the angle between the driving rod 221 and the driven rod 222 gradually increases, in this case, the garbage bag 3 is arranged opposite to the driving unit 210, the weight is reasonably distributed, the center of gravity of the garbage can is located on or close to the axis of the garbage can, and the placement of the garbage can is more stable; and the garbage throwing port 110 is positioned in the middle of the can body, so that a user can more accurately throw garbage into the can body.

In another example, the driving unit 210 and the garbage bag 3 are disposed on the same side of the mounting frame 240, and when the grabbing unit 230 approaches the garbage bag 3, the included angle between the driving rod 221 and the driven rod 222 gradually decreases; when the grabbing unit 230 is far away from the garbage bag 3, the included angle between the moving rod 221 and the driven rod 222 is gradually increased.

As shown in fig. 2 and 3, the driven rod 222 and the grasping unit 230 are connected by a pivot structure having a first axis perpendicular to the moving direction of the grasping unit 230. The technical scheme is an implementation mode of how to drive the grabbing unit 230 through the connecting rod transmission mechanism, and has a simple, reliable and stable structure. The pivoting structure in this example may be a pin, screw, or the like for connecting the driven lever 222 with the grasping unit 230.

As shown in fig. 1 to 6, the transmission unit 220 includes a set of link transmission mechanisms disposed at both sides of the grabbing unit 230, and the action of the grabbing unit 230 in the horizontal direction is related to the action of the set of link transmission mechanisms in the vertical direction.

Compared with the existing transmission mode, the connecting rod transmission mechanism has the advantages of simple structure, lower manufacturing and replacing cost, easiness in obtaining higher precision, longer service life and better transmission stability, and the automatic bagging garbage can applying the connecting rod transmission mechanism has the advantages of stability and reliability in bagging.

The synchronization of the link transmission mechanism is well controlled, so that the rod body 233 of the grasping unit 230 is not easily inclined, and thus the reliability of bagging can be ensured. The jamming caused by the inclination of the grasping unit 230 due to the desynchronization of both ends of the grasping unit 230 is avoided.

Through the arrangement of a group of connecting rod transmission mechanisms, the reliability and the stability of power transmission can be ensured.

In one embodiment of the present technical solution, a set of transmission mechanisms are respectively connected to two ends of the grabbing unit 230, in this case, the set of link transmission mechanisms can be respectively disposed on the outer side wall of the installation frame 240, and the set of link transmission mechanisms are oppositely disposed, so that the link transmission mechanisms are hidden at the side portion of the installation frame 240, which is more beautiful and sanitary; meanwhile, the space of the garbage throwing port 110 is not occupied; in addition, the two ends of the grabbing unit 230 adopt the same transmission mode, the transmitted forces are basically the same, the moving synchronism of the two ends of the grabbing unit 230 is ensured, and the grabbing unit 230 is prevented from inclining in the moving process.

Another implementation manner of this technical scheme is that, the middle part of installation frame 240 is located to the connecting rod drive mechanism, and the connecting rod drive mechanism locates the middle part of rubbish input port 110 promptly, and one end of connecting rod drive mechanism is connected with the middle part of grabbing unit 230 among this technical scheme, and this kind of mode snatchs unit 230 and is difficult to the slope at the removal in-process middle part, has guaranteed the synchronism of grabbing unit 230 both ends.

Further, as shown in fig. 6 and 8, the group of link transmission mechanisms is associated with the action of the same driving unit 210, and is driven by the same driving unit 210, on one hand, the torque and the starting time of the group of link transmission mechanisms are the same, and especially when the group of link transmission mechanisms is connected with the two ends of the grabbing unit 230, the synchronism of the two ends of the grabbing unit 230 can be ensured, the grabbing unit 230 is prevented from tilting, and the transmission is stable and smooth; on the other hand, the cost is increased by the way that each transmission mechanism corresponds to one driving unit 210, the requirements on the synchronism and the precision of the group of driving units are improved, the design difficulty is increased, and the failure rate is improved compared with the technical scheme.
