[0002] As a daily necessity in people's daily life, there are many kinds of trash cans. The simplest trash can only includes a barrel body with an open top. Although this kind of trash can has a simple structure, its appearance is not beautiful enough. For example, the upper edge of the garbage bag will be exposed to the outside, and if the top of the garbage bag is not fixed, it is easy to slide into the barrel when throwing garbage, which is not convenient.

[0003] Therefore, some double-layer trash cans have appeared on the market, that is, an outer shell is set on the outside of the trash can body, and the trash bag is put in the inner barrel. The upper edge of the trash bag is pressed and covered by the outer barrel, which is beautiful in appearance and the trash bag is not easy to fall. Although the double-layer trash can has the above advantages, it also has certain defects. For example, when the whole trash can needs to be picked up, both the outer barrel and the inner barrel must be supported, otherwise the two are easily separated, which is inconvenient to transfer. In addition, the trash can does not have an automatic packing and sealing function. When the trash needs to be dumped, the user lifts the outer barrel, and the smell in the trash bag will be directly released.

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0032] like Figures 1 to 8 The embodiment of the present invention preferably provides a trash can, comprising an inner barrel body 1 with an upper opening and an outer barrel body 2 with a lower opening, the outer barrel body 2 can cover the outer side of the inner barrel body 1 from top to bottom, the inner barrel body 1 is respectively provided with a first card slot 3, a drawstring positioning area 4 and a notch 5 with an upper opening on both sides, the outer barrel body 2 is respectively provided with a bag carrying rod 6, a self-locking block 7 and a driving member 8 on both sides, the drawstring positioning area 4 is located above the bag carrying rod 6; the self-locking block 7, its telescopic It is movably arranged on the inner side of the outer barrel body 2, and can be engaged with or disengaged from the first slot 3; the bag lifting rod 6 is rotatably arranged on the inner side of the outer barrel body 2, and can be rotated toward the notch 5 and extended to be directly below the drawstring positioning area 4; the driving member 8 is respectively connected to the self-locking block 7 and the bag lifting rod 6, and can synchronously drive the self-locking block 7 to move and rotate with the bag lifting rod 6, and when the bag lifting rod 6 is in a connected state rotated to be directly below the drawstring positioning area 4, the self-locking block 7 is in a connected state disengaged from the first slot 3.

[0033] Specifically, a garbage bag with a drawstring is a relatively mature prior art, which can be packed by pulling the drawstrings on both sides to shrink the bag mouth of the garbage bag. The structural principle thereof will not be described in detail here. For reference, a garbage bag disclosed in Chinese Patent Publication No. CN217397438U can be referred to;

[0034] When in use, a garbage bag with a drawstring is placed in the inner barrel, and the drawstrings on both sides of the garbage bag are placed in the drawstring positioning areas one by one, the outer barrel covers the inner barrel, and the driving component drives the self-locking block to telescopically move relative to the inner wall of the outer barrel, so that the self-locking block can bulge outward or shrink inside the inner wall of the outer barrel. When the self-locking block is in a bulging state, the self-locking block can be plugged and matched with the first card slot of the inner barrel, and then the inner and outer barrels are in a connected state, which is convenient for users to move and transfer, and there is no need to hold the inner barrel for transportation;

[0035] On the contrary, when the self-locking block is in a retracted state, the self-locking block disengages from the first slot, and the outer barrel body and the inner barrel body are in a separable state. At this time, the bag lifting rod is driven by the driving component to rotate in the direction of the notch, and then the bag lifting rod rotates to be directly below the drawstring positioning area. Therefore, when the outer barrel body is disassembled and lifted from bottom to top, the bag lifting rod can abut against the drawstring of the garbage bag, causing the garbage bag to shrink when being packed, thereby realizing automatic packing of the garbage bag, and the packing of the garbage bag is related to the user's action of lifting the outer barrel body, satisfying the user's operating inertia.

[0036] Furthermore, a flange 11 is provided along the circumferential outer wall of the lower portion of the inner barrel body 1, and an exhaust hole 12 connected to the inner cavity thereof is penetrated through the circumferential side of the inner barrel body 1 and located above the flange 11. The outer barrel body 2 can cover the outer side of the inner barrel body 1 from top to bottom, and the lower end edge of the outer barrel body 2 is sealed and abutted against the upper side of the flange 11. A flow channel 13 is formed between the outer barrel body 2 and the inner barrel body 1, and the flow channel 13 is connected to the upper opening of the inner barrel body 1.

[0037] Specifically, when the outer barrel body is covered on the inner barrel body, the air in the inner cavity of the outer barrel body moves downward and enters the garbage bag to rapidly inflate the garbage bag, and the air between the garbage bag and the inner barrel body is discharged from the exhaust hole, thereby realizing the complete opening and use of the garbage bag;

[0038] When the outer barrel body is completely placed on the inner barrel body, the outer barrel body can seal and cover the exhaust hole, thereby effectively preventing mosquitoes and the like from entering the inner barrel body through the exhaust hole and breeding therein, and the air discharged from the exhaust hole can be pressurized and replenished into the garbage bag through the flow channel from the opening of the inner barrel body, thereby effectively preventing the exhaust hole from being unable to discharge the last air after the outer barrel body is completely placed on the inner barrel body, causing the garbage bag to form an inward bulge.

[0039] Furthermore, the driving member 8 includes a first spring 81, a connecting rod 82 and a button 83. First mounting cavities 84 are respectively provided on both sides of the outer barrel 2. The button 83, the first spring 81 and the bag-lifting rod 6 are respectively provided in the first mounting cavities 84; wherein the button 83 can reciprocate along the first mounting cavity 84 relative to the inner barrel 1 to move closer to or away from the inner barrel 1, the connecting rod 82 and the bag-lifting rod 6 are respectively rotatably provided in the first mounting cavity 84, and the bag-lifting rod 6 is located on the activity track of the button 83, and can The self-locking block 7 is subjected to the displacement and abutment rotation of the button 83, and has a first limiting groove 85. One end of the connecting rod 82 is movably abutted against the first limiting groove 85, and the other end abuts against the button 83. The first spring 81 abuts between the self-locking block 7 and the first mounting cavity 84 or between the button 83 and the first mounting cavity 84. The first spring 81 is used to make the self-locking block 7 initially in a connected state in which it is convexly inserted into the first card slot 3, and at the same time, the button 83 and the bag carrying rod 6 are in a relatively distant disengaged state.

[0040] When the button 83 is displaced toward the inner barrel body 1 by force, the button 83 abuts against one side of the bag lifting rod 6, so that the bag lifting rod 6 rotates and extends to just below the drawstring positioning area 4, and at the same time, the connecting rod 82 drives the self-locking block 7 to displace out of the first slot 3.

[0041] Specifically, in the initial state, the button is kept away from the bag lifting rod by the elastic force of the spring, and then the bag lifting rod is kept in a drooping state due to its gravity. At this time, the bag lifting rod and the drawstring positioning area are staggered. When the outer barrel covers the inner barrel from top to bottom or the outer barrel is lifted from the inner barrel from bottom to top, the bag lifting rod will not touch the garbage bag drawstring in the drawstring positioning area. At the same time, the button is driven by the connecting rod through the lever principle to keep the self-locking block in a connection state of being convexly plugged into the first slot, so that the inner barrel and the outer barrel are in a connection state.

[0042] When it is necessary to pack and replace the garbage bag, the user presses the button to compress the elastic force of the spring. At this time, the top rod on the button is displaced and pressed against one side of the bag lifting rod, so that the bag lifting rod rotates in the direction of the notch and rotates to just below the drawstring positioning area. At the same time, the button is transmitted through the connecting rod via the lever principle to make the self-locking block displace and shrink and disengage from the first slot, so that the inner barrel body and the outer barrel body are in a separable state. Then, when the user keeps pressing the button and lifts the outer barrel body upward, the bag lifting rod can then abut against the drawstring in the drawstring positioning area and lift and pull it upward, thereby realizing automatic packing and shrinking of the garbage bag. When it is completely lifted, the user releases the button to automatically put down the packed garbage bag. The packing of the garbage bag is related to the user's action of lifting the outer barrel body, which satisfies the user's operating inertia.

[0043] Furthermore, the inner side of the outer barrel body 2 is detachably connected to the cover shell 21, the first installation cavity 84 is formed between the cover shell 21 and the outer barrel body 2, and the first guide groove 22 and the second guide groove 23 are respectively arranged in the first installation cavity 84, the button 83 is arranged in the first guide groove 22 and can reciprocate along the depth direction of the first guide groove 22, the self-locking block 7 is arranged in the second guide groove 23 and can reciprocate along the depth direction of the second guide groove 23, a first through hole 24 is penetrated through one side of the outer barrel body 2 corresponding to the position of the first guide groove 22, the button 83 is partially exposed to the outside through the first through hole 24, and a second through hole 25 is penetrated through one side of the cover shell 21 corresponding to the position of the second guide groove 23, the self-locking block 7 can movably protrude outward from the outside of the cover shell 21 and cooperate with the first slot 3 through the second through hole 25.

[0044] Furthermore, when the spring loses its elasticity after being used for too long, the user can replace the spring by removing the cover, and the button is partially exposed outside the outer barrel through the first perforation, so that the user can directly press and lift the outer barrel.

[0045] Furthermore, the drawstring positioning area 4 includes two spaced protrusions 41 protruding from the outer peripheral side of the inner barrel body 1, and the notch 5 is correspondingly located between the two protrusions 41. The upper end of the protrusion 41 is concave with a second slot 42 that can be engaged with the drawstring. Then, the drawstring of the garbage bag is manually placed in the second slot to achieve the positioning of the drawstring.

[0046] Furthermore, the first guide groove 22 is concavely provided with a second limiting groove 26 on the circumference thereof, and one side of the button 83 is evenly provided with elastically deformable buckle strips 27 along the circumference thereof, and one side of the buckle strip 27 has a convex portion, which can be deformed and displaced with the buckle strip 27 and flexibly engaged in the second limiting groove 26. The buckle strip is then used to realize rapid installation of the button, and the convex portion of the buckle strip is flexibly engaged with the second limiting groove, so that when the button is displaced along the depth direction of the first guide groove, the convex portion of the buckle strip is synchronously displaced along the second limiting groove.

[0047] Furthermore, the outer barrel body 2 includes a first annular barrel body 28 with upper and lower openings and a cover body 29 that can be opened and closed and placed on the opening of the first annular barrel body 28. A flow guide flange 30 is provided along the circumference of the inner side of the first annular barrel body 28. The cross section of the flow guide flange 30 is set in an "L" shape, so that a flow guide groove is formed between the flow guide flange 30 and the first annular barrel body 28. The upper end side wall of the inner barrel body 1 is located in the flow guide groove and a gap is left between the flow guide flange 30. Then, the flow guide flange is used to guide the airflow entering the inner barrel body through the flow channel to enter the inner cavity of the garbage bag in a downward manner along the circumference, so that the garbage bag is inflated and expanded from the edge, so that the garbage bag is better expanded and fits the inner wall of the inner barrel body.

[0048] Furthermore, the cover 29 is rotatably arranged on the first annular barrel body 28 by a torsion spring, and the cover 29 is opened relative to the opening of the first annular barrel body 28 by the torsion spring, and a locking member 9 is arranged between the cover 29 and the first annular barrel body 28, and the cover 29 is kept closed to the opening of the first annular barrel body 28 by the locking member 9. Then, the user can put garbage into the garbage bag in the inner barrel body by opening and closing the cover, and the locking member can keep the opening of the outer barrel body closed, so that even if the garbage can is tipped over as a whole, the garbage in the garbage bag in the inner barrel body will not be dumped out, which is convenient for users to use.

[0049] Furthermore, the locking member 9 includes a snap-fit ​​component 91 and a second spring 92, and the cover body 29 has a second installation cavity 93, and the second installation cavity 93 is respectively connected to and penetrates the first opening and the second opening, and the snap-fit ​​component 91 is rotatably set in the second installation cavity 93, and the lower part of the snap-fit ​​component 91 passes through the first opening and is movably located on the lower side of the cover body 29, and the upper part of the snap-fit ​​component 91 passes through the second opening and is movably located on the upper side of the cover body 29, and the second spring 92 abuts between the second installation cavity 93 and the upper part of the snap-fit ​​component 91, and a second slot 42 is provided on one side of the lower part of the snap-fit ​​component 91, and the first annular barrel body 28 is provided with a hook portion 94 that can be engaged with the second slot 42. Then, through the elastic force of the second spring, the card connector rotates to maintain the connection state of the second card slot thereon and the hook portion. When the cover body needs to be opened, the user only needs to press the upper part of the card connector to compress the elastic force of the second spring. At this time, the second card slot of the card connector disengages from the hook portion as it rotates, and the cover body quickly opens due to the force of the torsion spring. Conversely, when closing the cover body, the user presses the cover body, and the card connector moves and abuts against the hook portion, and the guide inclined surface on the upper side of the hook portion causes the card connector to rotate, and the second card slot is engaged with the hook portion.

[0050] Furthermore, a hanging assembly is provided on one side of the outer barrel 2; wherein the hanging assembly includes a vacuum suction cup 95 and a hanging part 96, the hanging part 96 is fixedly connected to the outer barrel 2, and one side of the vacuum suction cup 95 has a connecting part 97 that can be hung with the hanging part 96. Then, the user can adsorb the suction cup to the place where the trash can needs to be hung, and then realize the wall hanging function through the hanging cooperation between the hanging part and the connecting part.

[0051] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
