For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0041] The multilayer structure and the multilayer garbage can according to the embodiments of the utility model are described below with reference to the drawings.

[0042] Referring to Figures 1 to 9 The utility model aims at providing an embodiment of a multilayer garbage can, which is illustrated in a two-layer structure, and the number of layers of the multilayer garbage can of the embodiment can be three or more.

[0043] Among them, Figure 1 is a use state schematic diagram of the garbage can of the embodiment, and Figure 5 is a structure schematic diagram of the storage state of the garbage can of the embodiment.

[0044] In the embodiment, the multilayer garbage can includes an upper barrel body and a lower barrel body 110, the upper barrel body and the lower barrel body 110 are the relative position concepts of the two barrel bodies in the use state, and the upper barrel body and the lower barrel body 110 refer to the two adjacent layers, not specifically the uppermost layer and the lowermost layer.

[0045] In some embodiments, the lower barrel body 110 can be stored in the upper barrel body, that is, the caliber of the upper barrel body is relatively large, and the caliber of the lower barrel body 110 is relatively small.

[0046] Therefore, in the use state, the internal space of the multilayer garbage can decreases from top to bottom, which is convenient for putting garbage and taking out garbage bags.

[0047] At the same time, since the bottom of the upper barrel body is in an open state, the bottom edge of the upper barrel body can be lowered to the ground, which is beneficial to reduce the overall height of the multilayer garbage can in the storage state, reduce the occupied space, and facilitate storage and transportation.

[0048] In some embodiments, the upper barrel can be received in the lower barrel 110 to meet different use requirements.

[0049] That is, one of the upper barrel and the lower barrel 110 can be received in the other, which is conducive to reducing the occupied space and facilitating packaging and transportation.

[0050] In some embodiments, the upper barrel and the lower barrel 110 can be formed by an injection molding process, so that the bottom caliber of the upper barrel is close to the top caliber of the lower barrel 110, or the bottom caliber of the upper barrel is smaller than the top caliber of the lower barrel 110, so that the bottom of the upper barrel intersects with the top of the lower barrel 110, reducing the gap between the bottom of the upper barrel and the top of the lower barrel 110 in the horizontal direction, facilitating the connection of the upper barrel and the lower barrel 110 together, and meeting the use requirements.

[0051] In some embodiments, the upper barrel and the lower barrel 110 can be formed by bending a metal plate, which reduces the weight and has high strength and is not easy to break.

[0052] Referring to Figure 2 , Figure 3 and Figure 4 , in order to simplify the structure of the multi-layer garbage can, the embodiment also provides a multi-layer structure, which comprises a connecting piece 140, the connecting piece 140 stably locates the upper barrel on the lower barrel 110, and meets the use requirements.

[0053] Specifically, the connecting piece 140 comprises a lap portion 150 lapped on the first top edge 130, a support portion 160 supporting the first bottom edge 120, and a connecting portion 170 connecting the lap portion 150 and the support portion 160, wherein the upper barrel has the first bottom edge 120, and the lower barrel 110 has the first top edge 130.

[0054] In summary, the connecting piece 140 is provided, the connecting piece 140 has the lap portion 150, the support portion 160 and the connecting portion 170, so that when the upper barrel is placed on the lower barrel 110, the lower barrel 110 can position and support the upper barrel through the connecting piece 140, so that the internal space of the upper barrel and the internal space of the lower barrel 110 can be used for storage, for example, to form a garbage can with higher specifications and larger capacity.

[0055] The connecting piece 140 is provided, and the connection structure and the driving structure between the upper barrel and the lower barrel 110 can be simplified, so as to achieve the purposes of simplifying the structure, reducing the cost, facilitating the operation and implementation.

[0056] Meanwhile, for the case that the upper barrel body and the lower barrel body 110 are both formed by bending metal plates, since the gap between the bottom of the upper barrel body and the top of the lower barrel body 110 in the horizontal direction is large, the connecting piece 140 can make up for the gap and meet the use requirements of specific application scenarios.

[0057] In some embodiments, at least one of the overlapping part 150 and the supporting part 160 can include abutting surfaces 180 abutting each other in the up-down direction, and side positioning surfaces 190 connecting the abutting surfaces 180.

[0058] In the present embodiment, the overlapping part 150 and the supporting part 160 are both provided with the abutting surfaces 180 and the side positioning surfaces 190, and the connecting piece 140 can also position the upper barrel body and the lower barrel body 110 in the horizontal direction, so as to avoid the movement of the upper barrel body relative to the lower barrel body 110.

[0059] In some embodiments, the first bottom edge 120 and the first top edge 130 can be staggered in the up-down direction, so that the upper barrel body is not prone to tilting.

[0060] In some embodiments, the first bottom edge 120 can be located outside the first top edge 130, so as to meet the requirement that the lower barrel body 110 is accommodated in the upper barrel body, avoid occupying the internal space of the lower barrel body 110, and not affect the effective volume of the multi-layer garbage can.

[0061] In some embodiments, the connecting piece 140 can be fixed to the upper barrel body, or the connecting piece 140 can be fixed to the lower barrel body 110, that is, the connecting piece 140 is first fixed to one of the upper barrel body and the lower barrel body 110 during production, and during use, only the assembly of the upper barrel body and the lower barrel body 110 is needed, so as to reduce the assembly of the connecting piece 140.

[0062] In the present embodiment, the case that the connecting piece 140 is fixed to the upper barrel body is shown, and in some embodiments, the connecting part 170 can have a clamping protrusion 200, and the first bottom edge 120 has a first side edge 210 clamped between the clamping protrusion 200 and the supporting part 160, that is, the upper barrel body is pressed down, so that the first bottom edge 120 of the upper barrel body presses the clamping protrusion 200, so that the clamping protrusion 200 avoids or the first bottom edge 120 avoids, and then the first side edge 210 of the first bottom edge 120 is clamped into the clamping protrusion 200 and the supporting part 160, so that the connecting piece 140 is fixed on the upper barrel body.

[0063] In some embodiments, the clamping protrusion 200 can be multiple and arranged around the connecting piece 140, so as to realize multi-point fixing.

[0064] In some embodiments, the first side edge 210 can be a straight edge or a round edge formed by bending a metal plate, which is easy to manufacture.

[0065] In some embodiments, the multi-layer structure can further comprise a limiting member 230, which is detachably arranged on the connecting member 140 or the upper barrel body. In this embodiment, the limiting member 230 is connected to the connecting member 140 to overcome the difficulty in installing the bottom edge of the upper barrel body made of a metal sheet.

[0066] In this embodiment, the limiting member 230 has a first limiting portion 240, and the lap portion 150 and the first limiting portion 240 form a first side limiting space. The first top edge 130 has a second side edge 220, which can be located in the first side limiting space, and the second side edge 220 and the first side limiting space cooperate to limit the upper and lower limits.

[0067] It is easy to understand that, by arranging the limiting member 230, the lap portion 150 and the first limiting portion 240 also clamp the second side edge 220 upward and downward, so that the upper barrel body and the lower barrel body 110 connected together in the use state can be carried as a whole, which is convenient for use.

[0068] In terms of assembly, the limiting member 230 can be installed after the upper barrel body is placed on the lower barrel body 110, or the limiting member 230 can be installed on the connecting member 140, and then the upper barrel body is placed on the lower barrel body 110. By pressing, the second side edge 220 can pass by the first limiting portion 240 and be clamped into the first side limiting space, completing the connection of the upper barrel body and the lower barrel body 110.

[0069] In some embodiments, the limiting member 230 can be detachably connected to the connecting member 140. The connecting member 140 has a positioning protrusion 250, and the limiting member 230 is provided with a positioning hole accommodating the positioning protrusion 250 and a locking screw connecting the positioning protrusion 250. The limiting member 230 is fixed to the connecting member 140 by the locking screw.

[0070] In some embodiments, the positioning protrusion 250 can be a boss with a hole.

[0071] In some embodiments, the positioning protrusion 250 can be tubular.

[0072] That is, the external thread of the locking screw will self-tap the internal surface of the positioning protrusion 250, completing the connection and fixation.

[0073] At the same time, the outer surface of the positioning protrusion 250 can match the limiting member 230 to complete positioning. At the same time, the positioning protrusion 250 can accommodate the threaded rod of the locking screw without affecting the arrangement of the lap portion 150 and the support portion 160.

[0074] In this embodiment, the positioning protrusion 250 is located on the side away from the first bottom edge 120 of the support portion 160, that is, the positioning protrusion 250 is located at the bottom of the support portion 160, without affecting the internal structure of the upper barrel body.

[0075] In some embodiments, the outer surface of the positioning protrusion 250 can be arranged with ribs to improve the strength of the positioning protrusion 250.

[0076] For the case that the connecting piece 140 is fixed to the lower barrel 110, similarly, the connecting part 170 has a clamping protrusion 200, the first top rod has a second side edge 220 clamped between the clamping protrusion 200 and the overlapping part 150.

[0077] Similarly, the multi-layer structure further includes a limiting piece 230, which is detachably arranged on the connecting piece 140 or the lower barrel 110, and the limiting piece 230 has a second limiting part, the supporting part 160 and the second limiting part form a second side limiting space, the first bottom edge 120 has a first side edge 210 which can be located in the second side limiting space, and the first side edge 210 and the second side limiting space cooperate to limit the upper and lower positions.

[0078] For the case that the connecting piece 140 is fixed to the lower barrel 110, this embodiment is not illustrated, and can be understood by the case that the connecting piece 140 is fixed to the upper barrel, which is not difficult.

[0079] In some embodiments, the number of limiting pieces 230 can be two, distributed on opposite sides of the upper barrel, reducing manufacturing costs and reducing the resistance of pressing assembly.

[0080] Referring to Figure 1 , Figure 5 and Figure 6 In some embodiments, the upper barrel can be provided with a barrel cover 260, which can cover the upper barrel to make the multi-layer garbage can closed, reducing the interference of mosquitoes and flies and the peculiar smell.

[0081] In some embodiments, the upper barrel can have a quick lock buckle 370 connected to the barrel cover 260, which can meet the needs of quick disassembly and assembly of the barrel cover 260 to facilitate the replacement of garbage bags.

[0082] Referring to Figure 6 and Figure 7 The quick lock buckle 370 includes a lock body 371, a hinge rod 372 hinged to the lock body 371, and a lock seat 373, and the barrel cover 260 is provided with a lock edge 374. In use, the lock body 371 hooks the lock edge 374, and then the lock body 371 is pressed to make the connection center of the lock body 371 and the hinge rod 372 deviate from one side of the control line to the other side of the control line. The control line is a straight line, which has two control points, one of which is the connection center of the hinge rod 372 and the lock seat 373, and the other is the contact position of the lock body 371 and the lock edge 374.

[0083] When the connection center of the lock body 371 and the hinge rod 372 is offset from one side of the control line to the other side of the control line, the hinge rod 372 keeps the state of the lock body 371, and the quick lock 370 cannot be opened without external force. When the barrel cover 260 needs to be disassembled, the lock is pried upward, and the connection center of the lock and the hinge rod 372 returns from the other side of the control line, so that the quick lock 370 can be opened.

[0084] In some embodiments, the quick lock 370 can be provided with two, and located on both sides of the length direction of the upper barrel body, to improve the fixing reliability.

[0085] For the case that the number of the quick lock 370 is one, the barrel cover 260 can be rotationally connected to the upper barrel body or connected to the upper barrel body in other forms, and the barrel cover 260 can also be fixed.

[0086] In some embodiments, the barrel cover 260 can be opened by hand pressing. The barrel cover 260 is provided with a button, the button is clamped into the cover body 390 of the barrel cover 260 under the action of a spring, the button is pressed by hand to move away from the cover body 390, and the cover body 390 is conveniently turned upward and opened.

[0087] To meet the needs of stepping on the cover and to avoid people touching the barrel cover 260 of the garbage can when throwing garbage, with reference to Figure 8 and Figure 9 The utility model also provides an embodiment of a cover opening mechanism 270.

[0088] In the embodiment, the cover opening mechanism 270 comprises an upper cover opening assembly 280 and a lower cover opening assembly 290. The lower cover opening assembly 290 is arranged on the top of the lower barrel body 110, and the upper cover opening assembly 280 is movably arranged on the top of the lower cover opening assembly 290. The lower cover opening assembly 290 is driven by the upper cover opening assembly 280 to open and close the barrel cover 260.

[0089] The upper cover opening assembly 280 is movably arranged on the top of the lower cover opening assembly 290, which means that when a multi-layer garbage can is used, the upper cover opening assembly 280 is located on the top of the lower cover opening assembly 290. When the multi-layer garbage can is in a storage state, the upper cover opening assembly 280 can be away from the top of the lower cover opening assembly 290 in various ways such as rotation, translation, extension, removal, etc., to reduce the occupied space and facilitate storage.

[0090] It is easy to understand that, in the embodiment, the upper cover opening assembly 280 is movably arranged on the top of the lower cover opening assembly 290. Therefore, when storage or transportation is needed, the upper cover opening assembly 280 can change its posture or position, for example, reach out or move away, to occupy less space on the top of the lower cover opening assembly 290, and facilitate storage.

[0091] When the garbage can is needed to be used, the upper lid opening assembly 280 is repositioned on the top of the lower lid opening assembly 290, and the lower lid opening assembly 290 can transmit the lid opening power to the can lid 260 through the upper lid opening assembly 280 to meet the lid opening requirement and facilitate the use

[0092] In the embodiment, a case that the upper lid opening assembly 280 can be removed is shown to simplify the connection structure and facilitate the operation and implementation.

[0093] For the lower lid opening assembly 290, the lower lid opening assembly 290 includes a lower box body 320 and a lower top rod 330 movably arranged in the lower box body 320.

[0094] In some embodiments, the lower end of the lower top rod 330 can be provided with a bent section 331, the footrest support 420 is provided with a semicircular hole 332 and a semicircular cover 333 closing the semicircular hole 332, the semicircular cover 333 is fixed on the footrest support 420 by screws, and the semicircular hole 332 and the semicircular cover 333 cooperate to form a circular hole accommodating the rotation of the bent section 331, the semicircular hole 332 and the semicircular cover 333 are along the axial section of the circular hole, and the up-down swing of the footrest support 420 can be converted into the lifting of the lower top rod 330 to meet the lid opening requirement.

[0095] In some embodiments, the top of the lower lid body 390 can be provided with a sliding hole cooperating with the lower top rod 330 to limit the position of the top end of the upper top rod 310, and facilitate the lower lid opening assembly 290 to drive the upper lid opening assembly 280.

[0096] In some embodiments, the upper lid opening assembly 280 can include an upper box body 300 and an upper top rod 310 movably arranged in the upper box body 300, and the lower top rod 330 lifts the upper top rod 310 to open the lid.

[0097] Since the upper top rod 310 is movably arranged in the upper box body 300, the upper top rod 310 can transmit the lifting movement of the lower top rod 330 upward to meet the lid opening requirement.

[0098] In some embodiments, the number of the upper lid opening assemblies 280 can be determined according to the number of the upper can bodies to adapt to the case that the garbage can is multi-layered.

[0099] In some embodiments, one of the upper box body 300 and the lower box body 320 is provided with a tapered positioning part 340, and the other of the upper box body 300 and the lower box body 320 is provided with a V-shaped positioning groove 350 accommodating the tapered positioning part 340, and the tapered positioning part 340 and the V-shaped positioning groove 350 cooperate to position the upper box body 300 relative to the lower box body 320.

[0100] In the embodiment, the upper box body 300 is provided with the V-shaped positioning groove 350 and the lower box body 320 is provided with the tapered positioning part 340.

[0101] It is easy to understand that, by setting the V-shaped positioning groove 350 and the tapered positioning portion 340, the upper cover opening assembly 280 and the lower cover opening assembly 290 are easily aligned, which meets the transmission needs of the lower ejector rod 330 and the upper ejector rod 310 and simplifies the installation.
