Description

Technical Field

[0001] This utility model relates to the field of trash can technology, specifically to a trash can. Background Technology

[0002] When multiple arc-shaped rings are sequentially joined along the depth of the trash can to form its body, the trash can's appearance becomes more aesthetically pleasing. However, when the wall thickness is uniform, the arc shape of the outer wall of the rings causes corresponding indentations or protrusions on the inner wall. Consequently, the inner wall of the trash can body formed by joining multiple rings has numerous indentations or protrusions, meaning it is not a smooth surface along the depth direction. When a trash bag is placed inside the trash can, these indentations or protrusions can obstruct the removal of the trash bag, making it difficult to take out and affecting the user experience. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] This utility model mainly addresses the shortcomings of the existing technology, specifically relating to a trash can that solves the technical problem that when multiple arc-shaped rings are sequentially spliced ​​along the depth direction of the trash can to form the body of the trash can, it is difficult to remove the trash bag, which affects the user experience.

[0005] (II) Technical Solution

[0006] This utility model relates to a trash can, including multiple bin rings, each of which includes a first part and a second part, the first part being arc-shaped and the second part being a smooth ring;

[0007] Multiple bin rings are spliced ​​together to form a bin body, such that the second parts of the multiple bin rings are sequentially spliced ​​together to form a smooth inner wall of the bin body, allowing the garbage bag to be removed without obstruction; the first parts of the multiple bin rings are sequentially spliced ​​together to form an outer wall of the bin body, and the outer wall has multiple arc-shaped surfaces arranged along the depth direction.

[0008] The advantages are: the bin ring is divided into two parts. The first part is curved, so that multiple rings can be joined together to form the outer wall of the bin. This allows the bin's appearance to be designed in different shapes as needed, improving its aesthetics. The second part is a smooth ring, so that multiple rings can form the smooth inner wall of the bin. This allows garbage bags to be installed inside the bin and then easily removed along the smooth inner wall. In other words, the shape of the first part does not obstruct the removal of garbage bags, resulting in a better user experience. Furthermore, the bin body is formed by joining multiple rings, allowing for adjustments in the number of rings to create different capacities to meet diverse user needs. Also, since the bin body is formed by joining multiple rings, only one mold is needed to produce the rings, which can then be combined to create bin bodies of different sizes, reducing production costs.

[0009] In one alternative embodiment, the first portion is connected to the second portion and arranged side by side along the depth direction, with the first portion located outside the second portion adjacent to the barrel ring.

[0010] In one alternative implementation, when multiple barrel rings are spliced ​​together to form the barrel body;

[0011] So that a cavity is formed between the first portion and the second portion of the adjacent barrel ring;

[0012] Alternatively, a cavity may be formed between the first portion and the second portion of the same barrel ring.

[0013] In one optional embodiment, the second part and / or the first part of the adjacent barrel ring are provided with a limiting part. When the first part of the adjacent barrel ring is inserted into the second part, the second part and the first part of the adjacent barrel ring are limited by the limiting part to fix the two adjacent barrel rings.

[0014] Alternatively, the thickness of the outer wall of the second part gradually decreases from the end closest to the first part toward the end furthest from the first part, so that when the first part of the adjacent barrel ring is inserted into the second part, the first part of the adjacent barrel ring is interference-fitted with the second part, thereby fixing the two adjacent barrel rings.

[0015] In one optional embodiment, the limiting part is a groove provided on the outer wall of the second part, and the groove is provided close to the first part. When the first part of the adjacent barrel ring is fitted into place along the outer wall of the second part, the first part of the adjacent barrel ring cooperates with the groove to limit the movement, so as to fix the two adjacent barrel rings.

[0016] In one alternative embodiment, the bucket also includes a bucket bottom, the bucket bottom including a bottom wall and an insertion portion surrounding the periphery of the bottom wall, the insertion portion engaging with a first portion and / or a second portion of the bucket ring.

[0017] In one optional embodiment, the shape of the insertion part is the same as the shape of the second part, so that the first part of the adjacent barrel ring is inserted into the insertion part to fix the barrel body to the barrel bottom;

[0018] And / or the bottom wall opposite the barrel body has several legs arranged in an array.

[0019] In one optional embodiment, a top ring is also included, the top ring having the same shape as the first part. The top ring is inserted into the ring on the top of the bin body, and is adapted to be fitted outside the ring and press the bag opening tightly when the bag opening is fitted onto the ring on the top of the bin body.

[0020] In one alternative embodiment, a bucket lid is also included, which is disposed on the top of the bucket body;

[0021] The bucket lid is detachably connected to the top ring;

[0022] Alternatively, the bucket lid can be fixedly connected to the top ring.

[0023] In one alternative implementation, the distance between two adjacent rings on the inner wall of the barrel is defined as S, where 0 < S ≤ 1 cm. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] This utility model relates to a trash can, including multiple bin rings 10, each bin ring 10 including a first part 11 and a second part 12, the first part 11 being arc-shaped and the second part 12 being a smooth ring; the multiple bin rings 10 are spliced ​​to form a bin body, such that the second parts 12 of the multiple bin rings 10 are sequentially spliced ​​to form a smooth inner wall of the bin body, allowing the trash bag to be removed without obstruction; the first parts 11 of the multiple bin rings 10 are sequentially spliced ​​to form an outer wall of the bin body, the outer wall having multiple arc-shaped surfaces arranged along the depth direction.

[0040] The bin ring 10 is divided into two parts. The first part 11 is arc-shaped, so that multiple bin rings 10 can be joined together to form the outer wall of the bin body. This allows the appearance of the bin body to be designed into different shapes as needed, making the trash can more aesthetically pleasing. The second part 12 is a smooth ring, so that multiple second parts 12 can form the smooth inner wall of the bin body. This allows the trash bag to be installed inside the bin body and then easily removed along the smooth inner wall. In other words, the shape of the first part 11 will not obstruct the removal of the trash bag, resulting in a better user experience. At the same time, the bin body is formed by joining multiple bin rings 10, and the number of bin rings 10 can be increased or decreased to form different capacities to meet different user needs. Furthermore, the bin body is formed by joining multiple bin rings 10, so only one set of molds is needed to produce the bin rings 10, which can then be combined into bin bodies of different specifications, reducing production costs.

[0041] The bin ring 10 is a basic component that makes up the bin body. In this example, the preferred cross-sectional shape of the bin ring 10 is an annular shape. When multiple bin rings 10 are spliced ​​together along the depth direction of the trash can, the trash can forms a cylinder. The depth direction of the trash can is the axial direction of the trash can. It can be understood that the cross-sectional shape of the bin ring 10 can be set to other shapes, such as triangular rings, quadrilateral rings, hexagonal rings, or racetrack rings, etc. The cross-sectional shape of the bin body formed by splicing them together will also be the same as the shape of the bin ring 10. To meet different user preferences, it can be understood that the trash can body can also be a columnar structure that is larger at the top and smaller at the bottom or smaller at the top and larger at the bottom.

[0042] The first part 11 of the barrel ring 10 is arc-shaped. The arc effect can be that the part between the two ends of the first part 11 protrudes or is concave in the direction away from the center of the barrel. Alternatively, part of the structure of the first part 11 can be arc-shaped, and the structure of the other part can be a smooth sidewall. Embossed patterns can also be provided on the first part 11. Since the first part 11 forms the outer wall of the barrel, it will make the appearance of the barrel unique. In this example, the two ends of the first part 11 are preferably curved inward towards the inside of the barrel, while the middle position of the first part 11 forms a smooth vertical plane. When multiple first parts 11 are spliced ​​together to form the outer wall of the barrel composed of multiple arc surfaces arranged along the depth direction, the shape of the barrel has a unique simple and three-dimensional aesthetic.

[0043] The second part 12 of the bin ring 10 is a smooth ring, meaning that at least the inner sidewall of the second part 12 is smooth, and the cross-sectional shape of this surface in the depth direction of the trash can is a straight line. This makes it so that when multiple second parts 12 are spliced ​​together, the entire inner sidewall of the bin forms a smooth sidewall, that is, the cross-sectional shape of the inner sidewall of the bin in the depth direction of the trash can is a straight line. This is equivalent to the inner sidewall of the bin forming a smooth cylindrical curved surface, making it easier to put on and take off the trash bag, preventing the trash bag from getting stuck, and providing a better user experience.

[0044] In one optional embodiment, the first part 11 and the second part 12 are connected and arranged side by side along the depth direction. The first part 11 is located outside the second part 12 of the adjacent barrel ring 10, so that the adjacent barrel rings 10 form a nested connection relationship. On the one hand, the installation is more convenient, and on the other hand, the installation is more stable and reliable. In this example, the size of the second part 12 is slightly smaller than the size of the first part 11, so that the second part 12 can be inserted into the first part 11 for installation and fixation. The installation method of the barrel ring 10 is exemplified as follows: the first part 11 of the first barrel ring 10 is nested outside the second part 12 of the second barrel ring 10 adjacent to the first barrel ring 10, and the first part 11 of the second barrel ring 10 is nested outside the second part 12 of the third barrel ring 10 adjacent to the other side of the second barrel ring 10, and so on, so that multiple barrel rings 10 can be assembled into a columnar barrel body.

[0045] When multiple bin rings 10 are spliced ​​to form the bin body, a cavity is formed between the first part 11 and the second part 12 of the adjacent bin ring 10. Since the first part 11 is arc-shaped, that is, both the outer and inner walls of the first part 11 are arc-shaped, the cavity is used to cover the inner wall of the first part 11. Even when the inner wall of the first part 11 protrudes towards the center of the bin body, the protrusion can be accommodated in the cavity, so as not to obstruct the application and removal of the garbage bag.

[0046] Understandably, the first part 11 and the second part 12 can be arranged side by side along the radial direction of the trash can (not shown in the figure), so that the bin ring 10 forms two layers. The first part 11 forms the outer wall of the bin ring 10, and the second part 12 forms the inner wall of the bin ring 10. When multiple bin rings 10 are spliced ​​together, the first part 11 of adjacent bin rings 10 cooperates with each other and / or the second part 12 cooperates with each other, so that multiple first parts 11 form the outer wall of the bin body, and multiple second parts 12 form the inner wall of the bin body.

[0047] When multiple barrel rings 10 are spliced ​​together to form the barrel body, a cavity is formed between the first part 11 and the second part 12 of the same barrel ring 10, and the cavity is used to cover the inner wall of the first part 11.

[0048] In one optional embodiment, the second part 12 and / or the first part 11 of the adjacent barrel ring 10 are provided with a limiting part 14. When the first part 11 of the adjacent barrel ring 10 is inserted into the second part 12, the second part 12 and the first part 11 of the adjacent barrel ring 10 are limited by the limiting part 14 to fix the two adjacent barrel rings 10.

[0049] The limiting part 14 is used to fix the two barrel rings 10. This example does not limit the structure of the limiting part 14, as long as it can prevent the relative separation of the two adjacent barrel rings 10. The limiting part 14 can be one of the following mating methods: slot-block mating, magnetic mating, adhesive / Velcro mating, etc. Taking magnetic mating as an example: a first magnetic element is provided on the first part 11, and a second magnetic element is provided on the second part 12 of the adjacent barrel ring 10. One of the first and second magnetic elements is a magnet, and the other is an iron block or a magnet with opposite poles. When the first part 11 and the second part 12 of the adjacent barrel ring 10 are installed together, the first and second magnetic elements magnetically engage, thus fixing the two adjacent barrel rings 10. Other mating methods are similar to magnetic fixing and will not be elaborated here. The limiting part 14 can be provided only on the first part 11, only on the second part 12, or both on the first part 11 and the second part 12, depending on the structure of the limiting part 14.

[0050] In this preferred embodiment, the limiting part 14 is a groove provided on the outer wall of the second part 12, and the groove is located close to the first part 11. When the first part 11 of the adjacent barrel ring 10 is fitted into place along the outer wall of the second part 12, the first part 11 of the adjacent barrel ring 10 cooperates with the groove to limit the positioning, thereby fixing the two adjacent barrel rings 10. In this embodiment, the end of the first part 11 away from the second part 12 is inserted into the groove for fixing, so that there is no need to set a separate structure on the first part 11, and the mold design difficulty is lower. More specifically, the outer wall of the second part 12 is provided with a limiting ridge protruding from its surface, and the groove is opened on the limiting ridge, so as not to damage the overall shape and strength of the second part 12. Furthermore, the thickness of the limiting ridge gradually increases from the end away from the first part 11 toward the end close to the first part 11, so that the first part 11 gradually locks in place when sliding along the side wall of the second part 12, thereby enhancing the firmness of the connection between the two adjacent barrel rings 10.

[0051] In another alternative embodiment, the thickness of the outer wall of the second part 12 gradually decreases from the end near the first part 11 toward the end away from the first part 11. When the first part 11 of the adjacent barrel ring 10 is inserted into the second part 12, the first part 11 of the adjacent barrel ring 10 is interference-fitted with the second part 12, thereby fixing the two adjacent barrel rings 10. Specifically, the outer wall of the second part 12 forms an inclined slope, so that the resistance gradually increases when the first part 11 slides along the side wall of the second part 12 until the two adjacent barrel rings 10 are directly locked together.

[0052] In one alternative embodiment, the bucket also includes a bucket bottom 20, which includes a bottom wall 21 and an insertion portion 22 surrounding the periphery of the bottom wall 21, the insertion portion 22 being inserted into and engaged with a first portion 11 and / or a second portion 12 of the bucket ring 10.

[0053] The bottom 20 is used to form the base of the trash can, so that when the bottom 20 is fitted with the body of the can, it forms a container with a bottom, which makes it easy to put trash bags and trash. Preferably, the bottom 20 includes a bottom wall 21 and a plug-in part 22. The bottom wall 21 forms the bottom plate of the bottom 20, and the plug-in part 22 is provided on the periphery of the bottom wall 21 so as to cooperate and fix it with the ring 10. In this example, the plug-in part 22 preferably forms a bowl-shaped structure around the periphery of the bottom wall 21.

[0054] In one optional embodiment, the shape of the insertion part 22 is the same as that of the second part 12, so that the first part 11 of the adjacent barrel ring 10 is inserted into the insertion part 22 to fix the barrel body and the barrel bottom 20. Since the outer side wall of the second part 12 is provided with a groove, the insertion part 22 is also provided with a groove, so that when the first part 11 is fitted onto the insertion part 22, the end of the first part 11 will be inserted into the groove to fix the barrel bottom 20 and the barrel ring 10.

[0055] Understandably, the bucket bottom 20 and the bucket ring 10 can be connected by magnetic attraction. Specifically, the insertion part 22 is provided with a first magnetic attraction element, and the bucket ring 10 is provided with a second magnetic attraction element. One of the first magnetic attraction element and the second magnetic attraction element is a magnet, and the other is an iron block or a magnet with opposite magnetic poles. When the insertion part 22 and the bucket ring 10 are inserted and connected, the first magnetic attraction element and the second magnetic attraction element cooperate to magnetically attract each other, thereby fixing the bucket bottom 20 and the bucket ring 10. Of course, the bucket bottom 20 and the bucket ring 10 can also be fixed by other structures, as long as the bucket bottom 20 and the bucket ring 10 will not easily separate.

[0056] The bottom wall 21, on the side opposite to the bucket body, has several legs 23 arranged in an array. The legs 23 are used to raise the height of the bucket bottom 20, thereby facilitating the cleaning of the ground at the bottom of the bucket bottom 20. In this preferred embodiment, the legs 23 are fixed to the bucket bottom 20 by an insertion method, and the legs 23 are arranged outwards around the center line of the bucket bottom 20 to improve the stability of the bucket body.

[0057] In an optional embodiment, a top ring 30 is also included. The top ring 30 has the same shape as the first part 11. The top ring 30 is inserted into the ring 10 on the top of the bin body and is adapted to be fitted outside the ring 10 to press the bag opening when the bag opening of the garbage bag is fitted onto the ring 10 on the top of the bin body.

[0058] The top ring 30 is used to cover the second part 12 that is exposed after several bin rings 10 are spliced ​​together, so that the design of the first part 11 with an arc shape from top to bottom is more beautiful. At the same time, the top ring 30 can also cover the bag opening that is exposed after the garbage bag is put on the back of the bin, making the garbage bin more beautiful overall.

[0059] In one optional embodiment, a bucket lid 40 is also included, which is disposed on the top of the bucket body; the bucket lid 40 is detachably connected to the top ring 30; that is, the bucket lid 40 is installed after the user has installed the bucket ring 10, the top ring 30 and the bucket bottom 20. Preferably, the bucket lid 40 includes a base 41 and a flip cover 42, wherein the flip cover 42 is rotatably mounted on the base 41 by a pivot and a torsion spring. The base 41 abuts against the top of the top ring 30. In order to facilitate disassembly and ensure the reliability of the abutment, the top of the base 41 has an outward flange, so that the connection between the base 41 and the flange forms an angle, and the top of the top ring 30 abuts against this angle, thereby preventing the base 41 and the top ring 30 from being too tightly locked and difficult to disassemble.

[0060] In an optional embodiment, a bucket lid 40 is also included, which is disposed on the top of the bucket body; the bucket lid 40 is fixedly connected to the top ring 30. Specifically, the bucket lid 40 includes a base 41 and a flip cover 42, wherein the flip cover 42 is rotatably mounted on the base 41 via a pivot and a torsion spring, and the top ring 30 is integrally formed with the base 41, so that after the bucket rings 10 and the bucket bottom 20 are installed, the bucket lid 40 and the top ring 30 can be directly installed together on the second part 12 exposed after splicing several bucket rings 10, which can reduce structural components and make installation faster and more convenient.

[0061] In one optional embodiment, the distance between two adjacent bin rings 10 on the inner wall of the bin body is defined as S, where 0 < S ≤ 1 cm. Specifically, the smaller the distance between the inner walls of the second part 12 of the two bin rings 10, the less likely the garbage bag will get stuck. The height of the first part 11 in the depth direction is made to be close to the same as the height of the second part 12 in the depth direction, so that the distance between the inner walls of the second part 12 of the two bin rings 10 approaches 0. In order to reserve installation margin and avoid installation difficulties caused by processing precision or product deformation, S is preferably 0.5 cm in this example.

[0062] In one optional embodiment, the bin ring 10 is further provided with a fixing part for fixing the garbage bag. That is, when the opening of the garbage bag is flipped over and fitted onto the second part 12 at the top of the bin ring 10, the fixing part can fix the opening of the bag to prevent the opening of the bag from slipping into the bin body. Preferably, the fixing part is a round hole opened on the second part 12, into which the opening of the garbage bag can be inserted for fixing. It is understood that the fixing part can also be a clip provided on the second part 12 for clamping the opening of the garbage bag. It is understood that the fixing part can also be a groove (not shown in the figure) provided on the second part 12. The groove extends downward from the top of the second part 12, so that when the opening of the bag is installed on the second part 12, the drawstring can be installed in the groove to fix the opening of the garbage bag, and it is also convenient to pull the drawstring to close the garbage bag.

[0063] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
