[0002] As a daily necessity in people's daily life, there are many types of trash cans. The simplest trash can only include a barrel with an open top. Although this type 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] As a result, some double-layer trash cans have appeared on the market. These are outer shells placed outside the main body of the trash can, with the trash bag placed inside the inner shell. The upper edge of the trash bag is pressed and hidden by the outer shell, creating an aesthetically pleasing appearance and preventing the trash bag from falling. While double-layer trash cans have these advantages, they also have certain drawbacks. For example, when lifting the entire trash can, one must hold onto both the outer and inner shells, otherwise the two can easily separate, making transfer inconvenient. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] like Figures 1 to 5 The embodiment of the utility model shown preferably provides a double-layer trash can with a snap-on structure, including an inner barrel body 1 with an upper opening and an outer barrel body 2 with a lower opening, and the outer barrel body 2 can cover the outer side of the inner barrel body 1 from top to bottom, and is characterized in that: a slot 3 is provided on the outer peripheral side of the inner barrel body 1, and a self-locking block 4 and a driving component 5 are respectively provided on the outer barrel body 2; the self-locking block 4 is telescopically arranged on the inner side wall of the outer barrel body 2, and it can be snapped into or out of the slot 3; the driving component 5 is connected to the self-locking block 4 for driving the self-locking block 4 to telescopically move relative to the outer barrel body 2.

[0027] Specifically, the self-locking block is driven by the driving member to telescopically move relative to the inner wall of the outer barrel, so that the self-locking block can bulge outward or retract into the inner wall of the outer barrel. When the self-locking block is in the bulging state, the self-locking block can be plugged into and matched with the 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 without having to hold the inner barrel for transportation.

[0028] When the self-locking block is in the retracted state, the self-locking block is separated from the slot of the inner barrel body. At this time, the outer barrel body and the inner barrel body are in a separated state. The user can directly disassemble the outer barrel body and replace the garbage bag in the inner barrel body.

[0029] Furthermore, the driving component 5 includes a spring 51, a connecting rod 52 and a button 53. The button 53 is telescopically movably arranged on the outer peripheral side of the outer barrel body 2. The connecting rod 52 is rotatably arranged on the outer barrel body 2. The self-locking block 4 has a first limiting groove 54. One end of the connecting rod 52 is movably abutted against the first limiting groove 54, and the other end is abutted against the button 53. The spring 51 abuts between the self-locking block 4 and the outer barrel body 2 or between the button 53 and the outer barrel body 2.

[0030] Specifically, the self-locking block is kept in a state of elastically protruding from the inner wall of the outer barrel body by the action of the spring. In the initial state, the self-locking block of the outer barrel body is kept plugged into and matched with the slot of the inner barrel body, meeting the daily transportation and displacement requirements of the trash can. When the outer barrel body needs to be disassembled and separated from the inner barrel body, the user can press the button to displace the button and press against one end of the connecting rod, causing the connecting rod to rotate. At this time, the other end of the connecting rod rotates and presses against the side wall of the first limiting groove of the self-locking block, so that the elastic force of the compressed spring causes the self-locking block to displace out of the slot, thereby realizing the separation of the outer barrel body and the inner barrel body.

[0031] The lower side of the self-locking block can be provided with a guide bevel, and then when the outer barrel body is mounted on the inner barrel body, the self-locking block abuts against the upper edge of the inner barrel body through the guide bevel, which can compress the spring force and cause the self-locking block to be in a retracted state relative to the outer barrel body until the self-locking block is aligned with the slot and reset by the action of the spring.

[0032] Furthermore, a cover shell 21 is provided on the inner side of the outer barrel body 2, and a first guide groove 22 and a second guide groove 23 are respectively formed between the cover shell 21 and the outer barrel body 2. The button 53 is provided in the first guide groove 22 and can move back and forth along the depth direction of the first guide groove 22. The self-locking block 4 is provided in the second guide groove 23 and can move back and forth along the depth direction of the second guide groove 23. A first through-hole 24 is provided on one side of the outer barrel body 2 corresponding to the position of the first guide groove 22, and the button 53 is partially exposed to the outside through the first through-hole 24. A second through-hole 25 is provided on one side of the cover shell 21 corresponding to the position of the second guide groove 23, and the self-locking block 4 can be movably protruded outward from the outside of the cover shell 21 and cooperate with the slot 3 through the second through-hole 25.

[0033] Furthermore, a second limiting groove 26 is concavely formed around the circumference of the first guide groove 22. Elastically deformable snap strips 27 are evenly distributed along the circumference of one side of the button 53. One side of each snap strip 27 has a convex portion that can deform and displace with the snap strip 27 and flexibly engage within the second limiting groove 26. The snap strips enable quick installation of the button, and the convex portion of the snap strip flexibly engages with the second limiting groove, so that when the button is displaced in the depth direction of the first guide groove, the convex portion of the snap strip is simultaneously displaced along the second limiting groove.

[0034] Furthermore, the cover 21 is detachably connected to the inner side of the outer barrel 2. When the spring loses its elasticity due to long-term use, the cover can be removed so that the user can replace the spring.

[0035] Furthermore, a hanging assembly is provided on one side of the outer barrel 2. The hanging assembly includes a vacuum suction cup 6 and a hanger 7. The hanger 7 is fixedly connected to the outer barrel 2. One side of the vacuum suction cup 6 has a connecting portion 8 that can be hung with the hanger 7. The user can then attach the suction cup to the place where the trash can is to be hung, and then connect the hanger with the connecting portion to achieve the wall-mounting function.

[0036] Furthermore, the inner barrel 1 is provided with exhaust holes 9 communicating with its inner cavity. There are a plurality of exhaust holes 9, which are arranged at intervals along the circumference of the outer barrel 1. When the outer barrel lid is placed on the inner barrel, air in the outer barrel cavity enters the garbage bag through the exhaust holes, causing the garbage bag to rapidly inflate, while the air between the garbage bag and the inner barrel is discharged through the exhaust holes.

[0037] Furthermore, the outer barrel body 2 includes an annular barrel body 28 with upper and lower openings and a cover plate 29 that can be opened and closed and placed on the upper opening of the annular barrel body 28. This makes it convenient for users to put garbage into the garbage bag of the inner barrel body by opening the cover plate.

[0038] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
