In another embodiment, the bag pressing mechanism includes driving assembly and a bag pressing parts 94. The driving assembly drives the bag pressing parts 94 to rotate below the first cover body 81, so that the bag pressing parts 94 can be in the first or second state. In the first state, the bag pressing parts 94 compresses the garbage bag 5 on the inner wall of the barrel body 1. In the second state, the pressing parts 94 relieves the pressure on the garbage bag 5.

Among them, the driving assembly has a variety of structures. One structure of the driving assembly, as shown in FIG. 12 and 13, is as follows: the driving assembly includes rotating shaft 95, transmission parts 96 and rotating parts 97. The rotating shaft 95 is rotatable and set on the first cover body 81. One end of the pressing parts 94 is fixed on the rotating shaft 95. One end of the transmission parts 96 fixedly connects to the rotating shaft 95. The middle of the rotating parts 97 hinges to the first cover body 81. One end of the rotating parts 97 hinges to the other end of the transmission parts 96. The rotating parts 97 spins around the hinge point driving the transmission parts 96 to turn, which drives the rotating shaft 95 and bag pressing parts 94 to turn.

Rotating shaft 95 is set on the side, away from the barrel body 1, of the first cover body 81. One end of the bag pressing parts 94 is fixed on the rotating shaft 95, the other end goes through the first cover body 81 and locates the other end of the bag pressing parts on the side, close to the barrel body 1, of the first cover body 81, namely, below the first cover body 81. The rotating shaft 95 turns driving the bag pressing parts 94 to turn. For the convenience of the bag pressing parts 94 rotating, shelter space can be set in the position, near the bag pressing parts 94, on the first cover body 81 to make bag pressing parts 94 rotates freely relative to the first cover 81. The bag pressing parts 94 has a rod shaped structure with a certain length, so that the bag pressing parts 94 can extend into the barrel body 1 to compress the garbage bag 5 on the inner wall of the barrel body 1.

Rotating parts 97 hinges to the first cover body 81. Two ends of the rotating parts 97 can turn around the hinge point. When the rotating parts 97 is turning anticlockwise around the hinge point, the end hinging the rotating parts 97 and the transmission parts 96 turns downward, driving the transmission parts 96 to turn downward, which drives the rotating shaft 95 to turn to the inner wall of the barrel body 1, compressing the bag 5 onto inner wall of the barrel body 1.

The bag pressing parts 94 turns toward the inner wall of the barrel body 1 from below the first cover body 81 to realize bag pressing. In the process of bag pressing, the bag pressing parts 94 firstly turns from below the first cover body 81 into the bag 5, and secondly turns toward and onto the inner wall of the barrel body 1 from inner of bag 5, to guarantee bag pressing parts 94 withholding the garbage bags 5. Manually adjusting the position of the garbage bags 5 is not required and effect of the bag pressing mechanism is improved.

Among them, there are many ways to control the rotating parts 97. The first way is to drive the rotating parts 97 to turn through the power system. For example, a motor is set on the first cover body 81 to drive the rotating parts 97 to turn around the hinge point. The power system can be electric system, pneumatic system or hydraulic system, etc. Namely, after automatic bag changing is completed, when the garbage bag 5 needs to be compressed, under control of motor, the end, away from the transmission parts 96, of the rotating parts 96 turns along the direction away from the barrel body 1, making the bag pressing parts 94 turn toward the inner wall of the barrel body 1 and compress the bag 5 onto the inner wall of the barrel body 1. When the garbage bag 5 needs to be loosened, the rotating parts 97 turns reversely under control of motor, making the bag pressing parts 94 turn along the direction away from the inner wall of the barrel body 1, so as to loosen and facilitate the removal of the garbage bag 5

The second way is to push the rotating parts 97 to turn by the mechanical structure. Specifically, as shown in FIG. 13, the end, away from the transmission parts 96, of the rotating parts 97 runs through and extends out the first cover body 81 along the height direction. When the first cover body 81 is closed on the barrel body 1, the barrel body 1 contacts with the end, extending out the first cover body 81, of the rotating parts 97 and pushes the rotating parts 97 to turn.

Rotating parts 97 has protruding block structure wide at one end and narrow at the other end. The wide end runs through and extends out the first cover body 81, and the narrow end is connected with the transmission parts 96. Due to one end of the rotating parts 97 extending out the first cover body 81, When the first cover body 81 is gradually covering the barrel cover body 1, barrel body 1 will first connects with the end, extending the first cover body 81, of the rotating parts 97. With the first cover 81 continued to move down, barrel body 1 will push up the end, extending out the first cover body 81, of the rotating parts 97 making rotating parts 97 turn, driving the rotating shaft 95 and bag pressing parts 94 on it to turn along the direction near the inner wall of barrel body 1, by the transmission parts 96. Then the garbage bag 5 is compressed onto the inner wall of the barrel body 1. When taking out the filled garbage bags 5, the first cover body 81 needs to open, afterwards it needs to close. By directly using closing the first cover body 81 automatically to drive the rotating parts 97 to turn, not only has this scheme simple structure, but also no extra motor driving mechanism is required. Not only can reduce the cost, but also won't occupy too much inner space, of the intelligent garbage can.

To be optimized, as shown in FIG. 13, accommodation cavity 814 is set on the first cover body 81. The opening of accommodation cavity 814 has a limit parts 815. Rotating parts 97 is set in and hinges to the sidewall of the cavity 814. The end, away from the transmission parts 96, of the rotating parts 97 runs through and extend out the bottom of accommodation cavity 814. The limit parts 815 is located between two ends of rotating parts 97 to limit the rotation angle of rotating parts 97. When any end of the rotating parts 97 turns to reach the limit parts 815, the rotating parts 97 can be stopped to limit the rotation angle of the rotating parts 97.

To be optimized, for the convenience of bag pressing 94 reset, releasing the pressure on garbage bags 5 to facilitate taking out garbage bags 5. Reset structure is also set on the first cover body 1, as shown in FIG. 14, including the torsion spring 98, which is set on the shaft hinging the rotating parts 97 and the first cover body 81. One end of torsion spring 98 connects with one end of the rotating parts 97, and the other end connects the other end. The other end of the rotating parts 97 driven by barrel body 1 rotates along the direction of away from the barrel body 1, can make torsion spring 98 produce elastic deformation. When the first cover body 81 moves away from the barrel body 1, the torsion spring 98 drives the rotating parts 97 to reset, making the bag pressing parts 94 loosen the garbage bag 5.

When the rotating parts 97 turns under the thrust of barrel body 1, torsion spring 98 causes torque. After the first cover body 81 left barrel body 1, the applied force on rotating parts 97 by barrel body 1 disappeared, the torsion spring 98 reset under the action of torque, making the rotating parts 97 rotate reversely and reset, which will drive the transmission parts 96, the rotating shaft 95 and the bag pressing parts 94 to turn reversely, to make the bag pressing parts 94 leave the inner wall of the barrel body 1, relieving pressure on the bage 5, which makes it easy to recycle garbage bags 5.

Through the first cover body 81 automatically covering on the barrel body 1, bag pressing parts 94 compresses garbage bags 5 on the inner wall of the barrel body 1. And through the first cover body 81 automatically leaving the barrel body 1, the bag pressing parts 94 relieves pressure on bag 5. Motor is not required in whole process, and without reducing the intellectualization of the intelligent garbage can, control logic of the intelligent garbage can is simplified and the cost of intelligent garbage can is reduced.

As shown in FIG. 12, the side, close to barrel body 1, of the first cover body 81 is provided with a holding slot 816. When the rotating parts 97 resets, the bag pressing parts 94 is driven to reset, making bag pressing parts 94 locate in the holding slot 816.

When the first cover body 81 opens, the rotating parts 97 turns reversely driving the bag pressing parts 94 to reset, making the bag pressing parts 94 back to the initial state. In the initial state, the bag pressing parts 94 is in the holding slot 816 on the first cover body 81, which can make the bag pressing parts 94 fit the first cover body 81. The bag pressing parts 94 will not stretch out the first cover body 81, further not to interfere with the space below the first cover body 81, making it easy for users to take out and change the bag 5 in barrel body 1. After users taking out the garbage bags 5, and bag changing is complted in the barrel body 1, the first cover body 81 automatically shuts down and covers on the barrel body 1, the bag pressing parts 94 turns in the state of perpendicular from parallel to the first cover body 81. In the state of the bag pressing parts 94 perpendicular to the first cover body 81, the bag pressing parts 94 can fit the inner wall of the barrel body 1, thus compressing the bag 5 on the inner wall of the barrel 1, so as to fix the garbage bag 5 to avoid falling off.

To be optimized, as shown in FIG. 13, the rolling parts 971 is also set on the rotating parts 97, which is rotatable and set on the end, running through the first cover body 81, of the rotating parts 97 and located on the side, close to the barrel body 1, of the rotating parts. The rolling parts 971 can be a roller to reduce the friction between the rotating parts 97 and the barrel body 1, and prevent the wear of the rotating parts 97 due to long term friction.

As shown in FIG. 14, the transmission parts 96 includes the third connecting rod 961 and the fourth connecting rod 962. One end of the third connecting rod 961 is fixed on the rotating shaft 95, the other end fixedly hinges to one end of the fourth connecting rod 962. and the other end of the fourth connecting rod 962 hinges to one end of the rotating parts 97. When the rotating parts 97 turns anticlockwise, the end, connecting the rotating parts 97, of the forth connecting rod 962 turns downward, wihle the other end turns upward, driving the end connecting the third connecting rod 961 and the forth connecting rod 962 to turn upward, and the end, connecting the third connecting rod 961 and the rotating shaft 95, to turn downward, so as to make the bag pressing parts 94 turn downward and fit the inner wall of barrel body 1. In other embodiments, the transmission parts 96 can be other transmission structures.

To be optimized, in order to improve the fixed stability of garbage bag 5, as shown in FIG. 12, there are two bag pressing mechanisms on the first cover body 81, through which garbage bag 5 is firmly compressed on the inner wall of the barrel body 1. And multiple bag pressing parts 94 can be set at intervals on each rotating shaft 95.

Another kind of structure of the driving assembly includes, as shown in FIG. 15 and FIG. 16, rotating shaft 95, revolving parts 99 and sliding parts 910. The rotating shaft 95 is rotatable and set on the first cover body 81, the bag pressing parts 94 is fixed on the rotating shaft 95, the revolving parts 99 is fixedly connected to the rotating shaft 95, and sliding parts 910 meshes the outer surface of the rotating parts 99. The sliding parts 910 is set movable along the height direction of the barrel body 81. When the sliding parts 910 moves it drives the revolving parts 99 to turn, which drives the rotating shaft 95 and the bag pressing parts 94 to turn.

The sliding parts 910 meshes with the revolving parts 99. When moving along the height direction of the first cover body 81, the sliding parts 910 can drive the revolving parts 99 to turn. The rotation of revolving parts 99, fixedly connecting with the rotating shaft 95 can drive the rotating shaft 95 to turn, which drives the bag pressing parts 94 to turn. Among them, sliding parts 910 and revolving parts 99 can be pinion rack structure or other transmission mechanism.

There are many ways to control the sliding parts 910 to move. The first way is to drive the sliding parts 910 to move through the power system, which can be electric system, pneumatic system or hydraulic system, etc.

The second way is to push the sliding parts 910 to move through the mechanical structure. Specifically, as shown in FIG. 16, the sliding parts 910 runs along the direction of the thickness through the first cover body 81. The top edge of the first cover body 81 can be equipped with a hole along its height direction. The sliding parts 910 is located inside the hole and its two ends stretches out the hole respectively. When the first cover body 81 covers on the barrel body 1, the barrel body 1 and the sliding parts will be connected to push the sliding parts 910 to move within the hole along the direction away from the barrel body 1, driving the revolving parts 99 to turn, which can drive the rotating shaft 95 and the bag pressing parts 94 on it to turn along the direction near the inner wall of the barrel body 1, compressing the bag 5 onto the inner wall of the barrel body 1.

The third way is that when the first cover body 81 is closed on the barrel body 1, repulsive magnetic force can be generated between the barrel body 1 and the sliding parts 910. The repulsive magnetic force push the sliding parts 910 to move along the direction away from the barrel body 1. Specifically, the sliding parts 910 can be equipped with the first magnetic parts, and the barrel body 1 can be equipped with the second magnetic parts correspondingly. The first and the second magnetic parts can produce repulsive magnetic. When the first cover body 81 aqqroaches the barrel body 1, the repulsive magnetic force produced by the first and the second magnetic parts push the sliding parts 910 to move along the direction away from the barrel body 1. The smaller the distance between the first cover body 81 and the barrel body 1 is, the stronger is the repulsive magnetic force between the first and the second magnetic parts, so as to improve driving force of sliding parts 910 and facilitate the movement of sliding parts 910.

In the second and the third movement way driving the sliders 910, as shown in FIG. 15, to avoid sliding parts 910 falling off the first cover body 81, a connecting rod 10 can be set on the first cover body 81. The connecting rod 10 and the rotating shaft are set on the same side of the first cover body 81. One end of the connecting rod 10 hinges to the first cover body 81, making the connecting rod 10 move relative to the first cover body 81. The other end of the connecting rod 10 fixedly connects with the sliding parts 910, which is an integration. When the first cover body 81 covers on the barrel body 1, the top surface of barrel body 1 and sliding parts 910 is connected to push sliding parts 910 to move along the direction away from the barrel body 1 and drive the connecting rod 10 to move upward, which makes connecting rod 10 leave the surface of the first cover body 81. When the sliding parts 910 resets it can drive the connecting rod 10 to move downward. When the connecting rod 10 moves to meet the surface of the sliding parts 910, the sliding parts 910 will cease to move downward to limit its own position.

Of course, there are other ways to limit the position of the sliding parts 910, for example, the hole on the first cover body 81 can be equipped with reset structure, which can be prominence. It can also be set on the top edge of the sliding parts 910. When the sliding parts 910 reset to move to the joint of the two prominences, it stop moving to limit its own position.

To be optimized, as shown in FIG. 16, to facilitate the sliding parts 910 reset, the connecting rod is equipped with reset structure, including fasteners 101 and the elastic parts 102. One end of the fastener is equipped with flange, the other runs through the connecting rod 10 and connects with the first cover body 81. The elastic parts is set on fasteners 101, one end of which connects with flange and the other end connects with the connecting rod 10 to make the sliding parts 910 reset so as to relive the pressure on the garbage bag 5 by the bag pressing parts 94

Fasteners 101 runs through the connecting rod 10 and connects with the first cover from 81. The sliding parts 910 moves along the direction away from the barrel body 1 under the action of barrel body 1, driving the connecting rod 10 to move upward around the hinge point. The elastic parts 102 is located between the flange on the fasteners and the connecting rod 10. The connecting rod 10 moving upward can compress the elastic parts and make it in the state of storage. When the first cover body 81 is opened and leaves the barrel body 1, the acting force of the barrel body 1 on the sliding parts 910 disappears, the compressed elastic parts 102 resets making the connecting rod 10 move downward, which drives the sliding parts 910 to move downward to reset, so as to reset the pressing bag parts 94.

Implementation example 4

In this example, in order to facilitate the replacement of the viscous parts 4 on the basis of example 1 or example 2 or example 3, as shown in FIG. 17 to FIG. 20, the viscous parts mounting assembly is involved, including base 11 and elastic laying 12. The base 11 is installed on the horizontal bar 32 of pendulum rod 3. One side of the base 11 is provided with installation groove 111, the top of installation groove 111 is provided with the first opening 112, and the side wall is provided with the second opening 113. The elastic layer 12 is set on the other side of the base 11. There is a clamping parts 121 on the elastic layer 12, which extends into the installation groove 111 from the bottom. The elastic layer 12 is made of elastic material and can be deformed when stressed.

Viscous parts 4 includes viscous surface 41 and non-viscous surface 42 set correspondly. The non-viscous surface 42 is provided with bayonet slot 421. The width of non-viscous surface 42 is larger than that of the first opening 112. When the viscous parts 4 is located in the installation groove 111, it will not escape from the first opening 112 of the installation groove 111.

Viscous parts inserts in the installation groove 111 from the second opening 113. The viscous surface 41 extends out the first opening 112, making the viscous surface 41 adsorb the garbage bags 5. The bayonet slot 421 on non-viscous surface clamped to the, fixing the viscous parts 4 in the installation groove 111. When pressing the elastic layer 12 to make the clamping parts 121 exit the installation groove 111, the clamping connection between clamping part 121 and bayonet slot 421 is canceled.

When Installing the viscous parts 4, inserts it from the second opening 113 on the side wall of the installation groove 111. Due to the clamping parts 121 extending into the installation groove 111, in the process of viscous parts 4 inserting into the installation groove 111, it will squeeze the clamping parts 121 downward. While the elastic layering 12 has elasticity, when viscous parts 4 squeezes the clamping parts 121 downward, the elastic layering 12 can bend and move downward, making the clamping parts 121 exit the installation groove 111 to facilitate viscous parts 4 moving within the installation groove 111, so that the viscous parts 4 completely inserts into the installation groove 111. Afterwards, the clamping parts 121 just corresponds bayonet slot 421 on the viscous parts 4. At this point, the viscous parts 4 relives extrusion force on the clamping parts 121, the elastic layering 12 reset under the effect of elasticity, making the clamping parts 121 back into installation groove 111 and extend into and clamp bayonet slot 421 on viscous parts 4. So that the viscous parts 4 is fixed in the installation groove 111.

When the elastic parts 4 needs to be replaced, push down the elastic layer 12 to make the clamping parts 121 withdraw from the installation groove 111, removing the clamping parts 121 from the bayonet slot 421. Then the viscous parts 4 can be removed from the installation groove and replaced.

By setting the elastic layer 12 on the base 11, when installing the viscous parts 4 it only need to be inserted in the installation groove 111. When replacing the viscous parts 4, it only need to press the elastic layering 12 to remove the viscous part 4 from the installation groove 111. The whole process is easy and convenient and resolves the existing difficulty of detachment due to the viscous parts directly fixed on the horizontal bar 32, facilitating the replacement of viscous parts 4 periodically.

In order to improve the adsorption ability, on the mouth of garbage bag 5, of viscous parts 4, two installation grooves 111 can be set up on the base 11. There is a viscous parts 4 installed in each installation groove 111. The viscous parts 4 is fixed in the installation groove 111 through clamping parts 121.

Both base 11 and elastic layering 12 are elongated. Two installation grooves 111 are arranged at both ends of base 11 respectively. The middle parts of elastic layering 12 is fixed on base 11, and the two ends of elastic layering 12 are provided with clamping parts 121 respectively. The two ends of the base 11 are respectively equipped with viscous parts 4, which can produce a good adsorption effect on the mouth of garbage bag 5, to save the usage amount of viscous parts 4 and avoid waste.

The elastic layer 12 is set at the bottom of the base 11. When pressing the elastic layer 12, in order to facilitate the movement of itself, the bottom of the base 11 forms a certain hollow structure. After the bottom of the base 11 is mounted on the horizontal bar 32, the elastic layer 12 can move freely at the bottom of the base 11 under the action of external forces.

Preferably, as shown in FIG. 20, the end face, extending into the installation groove 111, of the clamping parts 121 is an inclined surface 1211, and the lowest point of the inclined surface 1211 is set near the second opening 113 of the installation groove 111. When the viscous parts 4 inserts in the installation groove 111, it can contact with inclined surface 1211 at the lowest point first, and then move downward on the inclined surface of clamping parts 121 to squeeze it. For convenience of the viscous parts 4 squeezing the clamping parts 121 out of the installation groove 111. And then make viscous parts 4 completely insert into the installation groove 111. Afterwards, viscous parts 4 is in place, the bayonet slot 421 on it is corresponding to clamping parts 121, which extends back into the installation groove 111 and the bayonet slot 421 on the viscous parts 4, without the extrusion force by viscous parts 4 to fix viscous parts 4 in the installation groove 111.

Preferably, as shown in FIG. 20, mounting hole 114 located near the installation groove 111 is also arranged on the base 11. The pressing parts 122 getting through the mounting hole, is set on the the elastic layering 12. Press the pressing parts 122 to make the clamping parts 121 exit the installation groove 111. The elastic layering 12 is agganged with the pressing parts 122. When the viscous parts 4 needs changing, push down the pressing parts 122 to make elastic layering 12 bend and move downward, which can drives the clamping parts 121 to move downward and exit the installation groove 111, canceling the clamping connecting of the claming parts 121 and the bayonet slot 421. The viscous parts 4 lost clamping force by the clamping parts 121 can easily remove the viscous parts 4 from the installation groove 111 and replace it.

Preferably, the elastic parts 102, set in the installation grooev 111 is also involved. The the viscous parts 4 is fixed in the installation grooev 111. When the elastic parts 102 generates deformation and the clamping parts 121 is released from the bayonet slot 421, the elastic parts 102 resets to pop the viscous parts 4 out of the installation groove 111. This implementation takes advantage of the feature that elastic parts 102 can automatically recover from deformation. When replacing the viscous parts 4, it can automatically eject from and leave the installation groove 111 to facilitate the removal of the viscous parts 4 and slove the porblem of inconvenience of manual removing of the viscous parts 4 for the users.

Elastic parts 102 can be a variety of forms, for expample, it can be spring, set in the installation groove 111 and one end connects with the installation groove 111. When the viscous parts is inserted in the installation groove 111 from the second opening 113, and fixed in the installation groove 111 by the the clamping parts 121, squeeze the spring to make it deform, pressing the pressing parts 122 to cancel the clamping connection of the claming parts 121 and the bayonet slot 421, to make the elastic parts 102 reset without extrusion force, and eject the viscous parts 4 the installation groove 111.

As shown in FIG. 19 to FIG. 21, elastic parts 102 can be a torsion spring. The middle of the torsion spring is fixed on the side, away from the installation groove 111, of the base 11, The bottom of the base has two limit holes 1111. One end of the torsion spring stretches into a limit hole 1111, the other end into another hole 1111. The viscous parts 4 inserts in the installed installation groove 111 driving two ends of the torsion spring to move within the limit holes 1111, making the torsion spring produce deformation. A fixed shaft 115 is arranged on the side, away from the installation groove 111, of the base 11. The fixed shaft 115 is arranged on the same side of the base 11 as the elastic layer 12, and the middle parts of the torsion spring is fixed on the fixed shaft 115. When the viscous parts 4 is inserted and fixed in the installation groove 111, the two ends of the torsion spring will be compressed. so that the torsion spring will deform and enter the compression state. When the clamping parts 121 is removed from the fixation of the viscous parts 4, the torsion spring resets and pops the viscous parts 4 out of the installation groove 111, so as to remove the viscous parts 4 quickly.

In one embodiment, as shown in FIG. 20, the viscous parts 4 includes the bottom plate 43 and the sticky block 44. One side of the sticky block 44 adheres to the bottom plate 43, the other side extends out the first opening 112. The bayonet slot 421 is arranged on the bottom plate 43. The width of the bottom plate 43 is greater than that of the first opening 112 and the height of bottom plate 43 matches that of the installation groove 111. When the viscous parts is installed in the installation groove 111, the sticky block 44 on the the bottom plate 43 extends out from the first opening in the installation groove 111, and the bottom plate 43 clamps with the installation groove 111, to avoid the viscous parts 4 escaping from the first opening 112 of the installation groove 111. In other embodiments, the viscous parts 4 may also be a stepped structure formed by viscous blocks. One side of viscous block is viscous surface 41, and the other side set opposite to viscous surface 41 is non-viscous surface 42. The area of viscous surface 41 is less than that of non-viscous surface 42, so that the whole viscous block will not escape from the first opening 112 of the installation groove 111. The number of clamping parts 121 or bayonet slot 421 is two. The two bayonet slots 421 are located on both sides set in opposite of the bottom plate 43, which can improve the stability to the viscous parts 4.

Preferably, as shown in FIG. 22, barrel 1 is also arranged with the viscous parts protection agency, which can be viscous protection plate 131, corresponding to horizontal bar 32, and set on the opening of barrel body 1, to locate the horizontal bar 32 below the viscous protection plate 131, so as to prevent stains from garbage bags 5 and garbage bags contacting with viscous parts 4, and prevent the viscous parts 4 being contaminated and affect its viscosity, avoiding subsequent bags 5 changing be affected.

As shown in FIG. 9 and 10, viscous parts protection agency also can be small cover plate 132 and rubber strip protection piece 133. The small cover plate 132 is set at opening of barrel body 1 and above the viscous parts 4. The rubber strip protection piece 133 is set on the horizontal bar 32 and below the viscous parts 4. When the pendulum rod 3 swing back to the front wall of the barrel from the bag box 2 direction to open the bag 5 mouth, driving the strip protection piece 133 to turn up, which put the viscous parts 4 in the hollow cavity with cooperatation of the small cover plate 132, so as to prevent stains from garbage bags 5 and garbage bags contacting with viscous parts 4, and prevent the viscous parts 4 being contaminated and affect its viscosity, avoiding subsequent bags 5 changing be affetced.
