Description

Technical Field

[0001] The utility model relates to the technical field of trash cans, in particular to a trash can. Background Art

[0002] As people's living standards improve, almost every household has several trash cans placed in different areas, such as the toilet, kitchen, living room or desktop.

[0003] In the process of using the existing trash can, a trash bag is placed on the inner wall of the trash can. The user usually places the trash bag in the trash can, opens the trash bag with his hands, and presses the air between the trash bag and the inner wall of the trash can to make the trash bag stick to the inner wall of the trash can. However, in general, the wall thickness of the trash bag is relatively thin. When the user opens the trash bag, the trash bag will stick to the user's hands, thereby affecting the laying efficiency of the trash bag. In order to solve the above problem, China Utility Model Patent CN218289057U discloses a trash can that lays the trash bag by moving the partition. The trash bag only needs to be installed on the partition in the inner barrel, and the outer The bucket is put into the inner bucket, and the lower pressure ring in the outer bucket contacts the lower pressure plate of the partition extending out of the inner bucket. The outer bucket moves downward while driving the partition downward. The partition, inner bucket and garbage bag form negative pressure, and the air under the partition is discharged through the hollow groove. The downward moving partition will drive the bottom of the garbage bag to move downward to complete the bagging. After the garbage bag is full and taken out, the partition can move upward with the help of the elasticity of the reset part and return to the initial position. Since there must be a gap between the partition and the inner bucket, when the garbage bag is placed on the partition, the above gap is easy to get stuck in the garbage bag during the upward movement of the partition, causing the garbage bag to rupture and cause the garbage to scatter. Utility Model Content

[0018] In an optional embodiment, the moving part includes a bottom plate and side plates arranged on the periphery of the bottom plate, and a accommodating cavity for accommodating the side plates is provided in the inner cylinder; when the moving part is driven to move in a direction away from the partition, the side plates are moved out of the accommodating cavity, and the air cavity is defined between the bottom plate, the partition plate and the side plates.

[0019] The advantage is that the bottom plate and the side plate form a bowl-shaped structure, and the movable part has a certain accommodating space, which can be used to store the air discharged from between the garbage bag and the side wall of the inner tube. The accommodating cavity makes it easy for the side plate to control the volume of the air cavity as it moves out of the accommodating cavity.

[0020] In an optional embodiment, the inner tube includes a first side wall and a second side wall, the first side wall and the partition form a placement cavity for accommodating garbage, the second side wall is arranged on the outside of the first side wall, and the accommodating cavity is formed between the first side wall and the second side wall.

[0047] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0048] The utility model relates to a trash can, comprising an inner tube 10, wherein a partition 11 is provided in a hollow area of ​​the inner tube 10, an air hole 110 is provided on the partition 11, and a moving part 20 is provided below the partition 11; when a garbage bag 40 is installed above the partition 11 of the inner tube 10 and the moving part 20 is driven to move in a direction away from the partition 11, the air between the garbage bag 40 and the inner wall of the inner tube 10 is discharged along the through hole into the air cavity 17 formed between the partition 11 and the moving part 20, so that the garbage bag 40 is attached to the inner wall of the inner tube 10.

[0049] When the moving part 20 is arranged at the lower part of the partition 11 and the garbage bag 40 is arranged above the partition 11, the moving part 20 will not touch the garbage bag 40 during the movement, thereby avoiding interference with the garbage bag 40, and the partition 11 will not change with the movement position of the moving part 20, so that the space for placing the garbage bag 40 will not change, and the partition 11 will not jam the garbage bag 40, thereby reducing the risk of the garbage bag 40 breaking, and providing a better user experience.

[0050] The inner tube 10 serves as the main body of the trash can. A hollow area is formed in the middle of the inner tube 10, and a garbage bag 40 can be set for throwing garbage. A partition 11 is set in the hollow area of ​​the inner tube 10, and the partition 11 divides the hollow area into two parts, an upper part and an lower part. The garbage bag 40 is placed in the hollow area of ​​the upper part of the partition 11 to accommodate the garbage, and a moving part 20 is set in the hollow area of ​​the lower part of the partition 11, and a moving space for the moving part 20 is formed, so that the moving part 20 moves in the space. In this example, the top of the preferred inner tube 10 is unobstructed, forming a garbage throwing port, and the bottom of the inner tube 10 is also unobstructed, which is convenient for the moving part 20 to exhaust during the movement. It can be understood that the bottom of the inner tube 10 can also be designed to have a plurality of exhaust holes 110.

[0051] The partition 11 is provided with an air hole 110 , which is used to connect the upper and lower parts of the partition 11 , so as to facilitate the discharge of air in the hollow area of ​​the upper part of the partition 11 to the lower part of the partition 11 .

[0052] When the garbage bag 40 is installed above the partition 11 of the inner tube 10, the user takes out the garbage bag 40 and places the garbage bag 40 in the hollow area above the partition 11 by simply stretching it out. Preferably, the bag mouth of the garbage bag 40 can be folded and sleeved on the outer wall of the tube mouth of the inner tube 10, so that the bag mouth of the garbage bag 40 is not easy to slip off during the laying process of the garbage bag 40. Further preferably, a structure for fixing the garbage bag 40 can be provided at the tube mouth of the inner tube 10 to enhance the reliability of the fixation of the garbage bag 40, such as providing a pressure ring to press the bag mouth of the garbage bag 40, or directly inserting the bag mouth of the garbage bag 40 into the socket or tightening it for fixation.

[0053] In this example, preferably, in the initial position, the movable member 20 is tightly arranged against the partition 11, which can maximize the use of the space in the hollow area below the partition 11. When the movable member 20 is driven to move away from the partition 11, an air cavity 17 is formed between the movable member 20 and the partition 11. As the movable member 20 gradually moves away from the partition 11, the volume of the air cavity 17 gradually increases, and the air pressure in the air cavity 17 increases, so that the air cavity 17 has a certain suction force, thereby extracting the air between the garbage bag 40 and the inner wall of the inner tube 10 through the through hole into the air cavity 17, so that negative pressure is formed between the garbage bag 40 and the inner wall of the inner tube 10, so that the garbage bag 40 is adsorbed on the inner wall of the inner tube 10, eliminating the need for the user to manually open the garbage bag 40, and providing a better user experience.

[0054] It can be understood that in the initial position, there is a certain distance between the moving part 20 and the partition 11, which forms an air cavity 17. As the moving part 20 gradually moves away from the partition 11, the volume of the air cavity 17 will gradually increase, thereby adsorbing the garbage bag 40 on the inner wall of the inner tube 10.

[0055] In an optional embodiment, the partition 11 is integrally arranged with the inner tube 10, which can enhance the stability of the partition 11 and avoid the partition 11 gradually moving downward as the garbage increases during use, thereby reducing the maximum capacity of the air cavity 17, the air that the air cavity 17 can store is reduced, and the air sucked from between the garbage bag 40 and the inner wall of the inner tube 10 is reduced, which reduces the laying efficiency of the garbage bag 40. At the same time, the integrated setting can reduce molds, reduce costs and assembly difficulty.

[0056] It can be understood that the partition 11 can be separately molded from the inner tube 10 and then fixed and assembled, such as setting a limiting structure on the inner wall of the inner tube 10. When the partition 11 is assembled to this position, the partition 11 cooperates with the limiting structure so that the limiting structure can fix the partition 11 to limit the movement of the partition 11 along the central axis of the inner tube 10. This example does not limit the structure of the limiting structure, and the limiting structure can be a slot, a block, a screw or other structure.

[0057] In an optional embodiment, there are multiple air holes 110, and the multiple air holes 110 are distributed in an array on the partition 11. Specifically, when multiple air holes 110 are provided, the exhaust efficiency is higher, and when there are fewer air holes 110, the garbage bag 40 is prevented from forming a cone and being adsorbed at the position of the air holes 110 and cannot be fully unfolded. When multiple air holes 110 are distributed in an array on the partition 11, the air between the garbage bag 40 and the partition 11 can be evenly discharged, so that the garbage bag 40 is more evenly attached to the partition 11 and the laying efficiency is higher. In this example, the preferred diameter of the air holes 110 is 5mm-10mm, and the interval between adjacent air holes 110 is 5mm-10mm. Although the diameter of the air holes 110 is small, the number of air holes 110 is set densely, so that the garbage bag 40 is evenly adsorbed on the partition 11, so as to realize the unfolding and laying of the garbage bag 40 in the inner tube 10.

[0058] In an optional embodiment, the moving member 20 is provided with a driving member 21, which extends from the side wall of the inner cylinder 10 and is suitable for being driven to drive the moving member 20 to move in a direction away from the partition 11. Specifically, the driving member 21 is used to drive the moving member 20 to move, so that one end of the driving member 21 is connected to the moving member 20, and the other end is driven by the user as a free end. The user can drive it by pedaling or manually pressing, or indirectly drive it through other structural members. In this example, the preferred driving member 21 is connected to the moving member 20. 20 is installed and fixed after being split into two parts. For example, an opening is provided on the side wall of the moving part 20, and the driving part 21 can pass through the side wall of the inner tube 10 and be inserted into the opening. When the moving part 20 is driven by the driving part 21, the number and setting position of the driving part 21 can be increased as needed, thereby improving the moving efficiency of the moving part 20 and reducing the possibility of the moving part 20 getting stuck during the movement. At the same time, when the driving part 21 extends out of the side wall of the inner tube 10, it can better enable the user to drive the moving part 20 outside the inner tube 10, thereby facilitating user operation.

[0059] In an optional embodiment, the driving member 21 extends from the side wall of the moving member 20 toward the inner cylinder 10 so that the driving member 21 extends from the side wall of the inner cylinder 10. Specifically,

[0060] In an optional embodiment, the side wall of the inner cylinder 10 is provided with a movable slide groove 14, and the driving member 21 extends from the side wall of the inner cylinder 10 through the movable slide groove 14; the driving member 21 is driven to move along the movable slide groove 14, driving the moving member 20 to move in the direction away from the partition 11. Specifically, the movable slide groove 14 is provided on the side wall of the inner cylinder 10. The movable slide groove 14 preferably extends in the vertical direction to limit the movement of the driving member 21 in the vertical direction, thereby driving the moving member 20 to move in the vertical direction. The provision of the movable slide groove 14 can limit the moving path of the driving member 21, so that the driving member 21 moves according to the specified path, and thus the moving member 20 moves according to the specified path, avoiding jamming during the movement of the moving member 20. When the driving member 21 is extended from the inner cylinder 10 through the movable slide groove 14, it is convenient for the user to drive the driving member 21 from the outside of the inner cylinder 10.

[0061] It is understandable that the movable slide groove 14 can also be set to a spiral shape, so that when the driving member 21 moves along the spiral movable slide groove 14, it drives the movable member 20 to move up and down while rotating.

[0062] In an optional embodiment, the movable member 20 includes a bottom plate 22 and a side plate 23 arranged on the periphery of the bottom plate 22, and the inner cylinder 10 is provided with a accommodating cavity for accommodating the side plate 23; when the movable member 20 is driven to move in a direction away from the partition 11, the side plate 23 moves out of the accommodating cavity, and the air cavity 17 is defined between the bottom plate 22, the partition 11 and the side plate 23. Specifically, the shape of the bottom plate 22 matches the shape of the partition 11, and the width of the bottom plate 22 is slightly larger than the width of the partition 11. The side plate 23 is arranged on the periphery of the bottom plate 22 and forms an annular structure, so that the bottom plate 22 and the side plate 23 form a bowl-shaped structure. The movable member 20 has a certain accommodating space, which can be used to store air discharged from between the garbage bag 40 and the side wall of the inner cylinder 10. The accommodating space is the air cavity 17, and the accommodating cavity facilitates the side plate 23 to control the volume of the air cavity 17 to gradually increase as the length of the air cavity moves out of the accommodating cavity.

[0063] It is understandable that when there is no side plate 23 , the air cavity 17 may also be composed of the partition plate 11 , the bottom plate 22 and the side wall of the inner tube 10 . In this case, the moving member 20 will move along the side wall of the inner tube 10 .

[0064] In an optional embodiment, the inner tube 10 includes a first side wall 12 and a second side wall 13, the first side wall 12 and the partition 11 form a placement cavity for accommodating garbage, and the second side wall 13 is arranged on the outside of the first side wall 12, and the accommodating cavity is formed between the first side wall 12 and the second side wall 13. Specifically, two side walls are provided so that the placement cavity and the accommodating cavity will not interfere with each other, effectively preventing the moving part 20 from causing damage to the garbage bag 40 arranged in the placement cavity. In this example, the first side wall 12 is preferably connected to the top of the second side wall 13, so that the longitudinal cross-section of the first side wall 12 and the second side wall 13 forms a "human" shape.

[0065] In an optional embodiment, a reset member 15 is further included, one end of which is connected to the inner cylinder 10 or the partition 11, and the other end is connected to the movable member 20. The reset member 15 is used to reset the movable member 20 after being driven to move, in preparation for the second laying of the garbage bag 40. The reset member 15 can be a spring, a tension spring, a flexible material, etc. In this example, a first mounting position 16 is preferably provided on the side wall of the inner cylinder 10, and a second mounting position 16 is provided on the side wall of the movable member 20, and the reset member 15 is arranged between the two mounting positions 16.

[0066] It can be understood that a first mounting position 16 is provided on the bottom of the partition 11 , a second mounting position 16 is provided on the side wall of the movable member 20 , and the reset member 15 is provided between the two mounting positions 16 .

[0067] It is understandable that the driving member 21 can serve as the second mounting position 16 .

[0068] In an optional embodiment, at least two reset members 15 are provided, and are evenly arranged on the circumference of the moving member 20. Specifically, when multiple reset members 15 are evenly provided, the reset of the moving member 20 can be smoother, and jamming can be avoided. In this example, there are preferably two reset members 15, which are respectively provided at the opposite ends of the moving member 20. When multiple reset members 15 are provided, they are evenly arranged on the circumference of the moving member 20 so that the distance between two adjacent reset members 15 is the same.

[0069] In an optional embodiment, a plurality of mounting positions 16 are provided on the inner cylinder 10 or the partition 11, and the reset member 15 is adapted to be connected with any of the mounting positions 16 according to its own reset force. Specifically, the preferred mounting position 16 in this example is a hole-shaped structure, and one end of the reset member 15 is inserted into the hole-shaped mounting position 16 for fixation, which is simple to assemble. It can be understood that the mounting position 16 can be a raised limiting column, so that one end of the reset member 15 can be hung on the limiting column for fixation. The preferred mounting position 16 in this example is spaced apart in the vertical direction of the side wall of the inner cylinder 10. Multiple mounting positions 16 are provided so that the user can connect the reset member 15 to different mounting positions 16 according to needs. When the reset force of the reset member 15 is large, the reset member 15 can be installed in a relatively low mounting position 16. When the reset force of the reset member 15 is small, the reset member 15 can be installed in a relatively high mounting position 16. The reset member 15 is prone to fatigue when used for a long time, which will affect the reset efficiency of the reset member 15. When multiple mounting positions 16 are provided, the user can freely adjust the mounting position 16 of the reset member 15 according to the reset force of the reset member 15 to improve the reset efficiency of the reset member 15.

[0070] In an optional embodiment, an outer cylinder 30 is further included. When the outer cylinder 30 is sleeved from the top to the bottom of the inner cylinder 10, the outer cylinder 30 drives the moving part 20 to move in the direction away from the partition 11. Specifically, the outer cylinder 30 forms the outer shell of the trash can. The outer cylinder 30 and the inner cylinder 10 are designed as separate bodies, and the two can be assembled into one by sleeve. In this example, preferably, the outer cylinder 30 drives the moving part 20 to move in the direction away from the partition 11 during the process of being sleeved relative to the inner cylinder 10, so that the garbage bag 40 is simultaneously attached to the side wall of the inner barrel during the process of sleeved outer cylinder 30, and no separate action is required for bag laying. The driving method is simple and the bag laying efficiency is high. The weight of the outer cylinder 30 is preferably greater than the weight of the moving part 20, so that when the outer cylinder 30 pushes the moving part 20 to the farthest end away from the partition 11, the outer cylinder 30 can keep the moving part 20 in the farthest end state by its own gravity.

[0071] It can be understood that a limiting structure for limiting the moving part 20 can be provided at the farthest end of the inner cylinder 10, so that the moving part 20 is limited by the limiting structure when it is driven by the outer cylinder 30 to move to the farthest end. When the outer cylinder 30 is removed, the limiting structure can also cancel the limit on the moving part 20. Of course, the user can also manually release the limit on the moving part 20 by the limiting structure.

[0072] It can be understood that when the outer cylinder 30 moves relative to the inner cylinder 10 to separate from the inner cylinder 10, the moving member 20 has no driving force, so that the moving member 20 is driven by the reset member 15 and moves toward the direction close to the partition 11, so that the moving member 20 is reset to facilitate the next installation of the garbage bag 40. Of course, the moving member 20 can also be reset and moved by manual drive of the user.

[0073] In an optional embodiment, the movable member 20 is provided with a driving member 21 that partially extends out of the side wall of the inner cylinder 10; when the outer cylinder 30 is mounted relative to the inner cylinder 10, the end of the outer cylinder 30 abuts against the driving member 21 and drives the driving member 21 to move, thereby driving the movable member 20 to move away from the partition 11. The structure is simple and the operation method is also simple.

[0074] In an optional embodiment, the mouth of the garbage bag 40 is fixedly mounted at the mouth of the inner tube 10. Specifically, the mouth of the garbage bag 40 can be fixed to the garbage bag 40 by a pressing ring or an insert. Of course, it can also be fixed by other structures, as long as the garbage bag 40 is not easy to slip after being put on. When the mouth of the garbage bag 40 is fixed at the mouth of the inner tube 10, the garbage bag 40 can be fixed to prevent the mouth of the garbage bag 40 from slipping, and at the same time, a certain amount of air is maintained between the garbage bag 40 and the inner tube 10, so that when the area of ​​the accommodating cavity is expanded and air is exhausted, the air between the garbage bag 40 and the inner tube 10 is exhausted and cannot be replenished, thereby generating negative pressure so that the garbage bag 40 is attached to the side wall of the inner barrel, and the laying efficiency of the garbage bag 40 is higher.

[0075] In an optional embodiment, it further includes an outer cylinder 30 that is sleeved relative to the inner cylinder 10. When the inner cylinder 10 and the outer cylinder 30 are sleeved, the top of the outer cylinder 30 cooperates with the top of the inner cylinder 10 to fix the bag opening of the garbage bag 40. Specifically, after the sleeve is completed, the tops of the inner cylinder 10 and the outer cylinder 30 will form an abutment state, so that the garbage bag 40 is clamped at the abutment point between the inner cylinder 10 and the outer cylinder 30, that is, the garbage bag 40 is fixed to prevent the garbage bag 40 from slipping, and at the same time, it can also limit the negative pressure between the garbage bag 40 and the side wall of the inner cylinder 10 from decreasing or even disappearing, causing the garbage bag 40 to be detached from the inner wall of the inner cylinder 10.

[0076] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
