Description

Technical Field

[0001] This utility model relates to the field of trash can technology, and in particular to a trash can that is easy to put on a trash bag. Background Technology

[0002] With the continuous development of technology in the home living field, various types of trash cans have emerged to meet people's needs for garbage disposal. Trash cans are usually composed of a body and a lid, with a certain capacity to hold garbage. The lid serves to cover the garbage and prevent odors from escaping, and is generally equipped with a foot-operated or sensor-operated opening device.

[0003] In related technologies, when putting a garbage bag on a trash can, the garbage bag needs to be put on the can body little by little, so that the garbage bag can cover the inner wall of the can body evenly. After the garbage bag is put on, the excess bag opening is usually folded over to the edge of the trash can to fix it.

[0004] However, the aforementioned devices have several drawbacks in practical use. Garbage bags are usually stored in rolls, and during the process of tearing them off and opening them, the tight fit between the bags and the static electricity generated by the plastic makes it difficult to unfold the bag smoothly. Often, multiple shakes or manual pulling are required to barely unfold the bag. Even then, due to static electricity, the bag cannot completely adhere to the inner wall of the trash can. When placing lightweight waste such as paper, this waste is easily attracted to the un-unfolded portion of the bag, preventing the trash can's usable volume from being fully utilized and reducing waste collection efficiency.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] See Figures 1-10 This invention illustrates a preferred embodiment of a trash can that facilitates the use of trash bags, comprising: a body 100, a lid 200, and a bag-supporting device 300.

[0039] The bin body 100 is used to hold garbage and provide a certain space for garbage storage. The bin body 100 has a receiving cavity to determine the capacity of the bin. The bin body 100 can be round or square.

[0040] The lid 200 is attached to the top of the bin body 100 and covers it. The lid 200 is sized to match the top of the bin body 100, completely covering it. The lid 200 is used to cover the garbage, preventing it from being exposed and reducing odor diffusion. The lid 200 has sufficient thickness to accommodate a receiving groove 210, which can be located at the center of the lid 200. The opening of the receiving groove 210 faces downwards and is used to accommodate the bag support device 300.

[0041] The bag-supporting device 300 can be housed in the receiving slot 210 without taking up extra space. When not in use, the bag-supporting device 300 is hidden in the lid 200, without affecting the daily use of the garbage can as a regular garbage can, which is easy to put on garbage bags. The bag-opening device 300 includes a telescopic mechanism 310 and an opening mechanism 320. The telescopic mechanism 310 can be an electric push rod, a pneumatic telescopic rod 311, etc. The telescopic mechanism 310 is connected to the inner top wall of the lid 200, which supports and holds the bag-opening device 300. The opening mechanism 320 is connected to the telescopic mechanism 310. The telescopic mechanism 310 can drive the opening mechanism 320 to move vertically up and down, either inserting or removing the opening mechanism 320 into or out of the bin body 100. Specifically, when the garbage bag needs to be opened, the telescopic mechanism 310 extends, causing the opening mechanism 320 to descend into the bin body 100. After the garbage bag is flattened, the telescopic mechanism 310 retracts, causing the opening mechanism 320 to extend out of the bin body 100 and be housed within the lid 200. The opening mechanism 320 can extend horizontally to open the garbage bag and can retract horizontally to avoid obstructing the garbage bag. In its extended state, the opening mechanism 320 pushes the garbage bag against the inner wall of the garbage bin, eliminating the static electricity and folding problems encountered when traditional garbage bags are unfolded. In its retracted state, it prevents the unfolded garbage bag from being disturbed and from affecting normal garbage disposal in the garbage bin. Illustratively, the opening mechanism 320 consists of four cross-shaped support rods, the surface of which is covered with a layer of soft silicone. This effectively protects the garbage bag from being torn and increases friction with the garbage bag, ensuring the effective opening.

[0042] In this embodiment, preferably, refer to Figure 3 , Figure 4 and Figure 6 The telescopic mechanism 310 includes a telescopic rod 311 and a first driving device. The telescopic rod 311 includes a fixed cylinder 3111 and multiple movable cylinders 3112. The fixed cylinder 3111 serves as the basic part of the telescopic mechanism 310 and is connected to the inner top wall of the bucket lid 200, serving to support and fix the bag-holding device 300. The fixed cylinder 3111 is telescopically connected to the adjacent movable cylinder 3112, and the multiple movable cylinders 3112 are sequentially telescopically connected, which can be nested between the cylinder walls to make the telescopic range larger, so as to realize the function of sending the opening mechanism 320 into the bucket and accommodating it in the receiving groove 210. The opening mechanism 320 is set on the movable cylinder 3112 and extends or retracts vertically through telescopic movements, which is responsible for the lifting and lowering of the opening mechanism 320. The first driving device can drive the movable cylinder 3112 to extend or retract vertically. The first driving device can drive the movable cylinder 3112 to extend or retract vertically by electric, pneumatic or mechanical means, ensuring that the telescopic rod 311 completes the predetermined telescopic movement without manual intervention.

[0043] In this embodiment, preferably, refer to Figure 3 and Figure 8 The telescopic rod 311 is a round rod, which ensures a uniform force distribution during operation of the telescopic mechanism 310, reducing friction and improving the smoothness of movement during extension and retraction. The diameter of the fixed cylinder 3111 is smaller than the diameter of the movable cylinder 3112. The diameter of the multiple movable cylinders 3112 increases radially, forming a nested telescopic structure. That is, the outer diameter of each movable cylinder 3112 decreases from the outermost to the innermost layer, and the outermost movable cylinder 3112 is the last extension of the telescopic rod 311. This allows the telescopic rod 311 to provide stable support when extended and minimize space occupation when retracted.

[0044] In this embodiment, preferably, refer to Figures 3-10 The opening mechanism 320 includes a movable ring 321, multiple support rod assemblies 322, and a second drive device 323. The shape of the movable ring 321 is determined by the shape of the telescopic mechanism 310. The telescopic mechanism 310 is a circular telescopic rod 311, so the movable ring 321 is a circular ring structure. The movable ring 321 serves as the core support part of the opening mechanism 320 and is arranged around the movable cylinder 3112. The inner diameter of the movable ring 321 is slightly larger than the outer diameter of the movable cylinder 3112, which has the largest diameter. Under the control of the second drive device 323, it can move up and down vertically along the outer edge of the movable cylinder 3112, thereby driving the support rod assembly 322 to perform corresponding opening and closing actions. Multiple support rod assemblies 322 are distributed circumferentially around the movable ring 321 to apply pressure evenly inside the garbage bag from multiple directions, allowing the garbage bag to unfold evenly. Each support rod assembly 322 includes a first support rod 3221 and a second support rod 3222. One end of the first support rod 3221 is pivotally connected to the movable ring 321, allowing it to rotate freely relative to the ring. The other end of the first support rod 3221 is hinged to the opening end 3223 of the second support rod 3222 for flexible angle adjustment. The opening end 3223 is used to open the bag. The end of the second support rod 3222 away from the opening end 3223 is pivotally connected to the movable cylinder 3112 with the largest diameter. The first support rod 3221 serves as a connector and allows rotation; during the raising and lowering of the movable ring 321, the first support rod 3221 drives the second support rod 3222 to extend and retract together. The second drive device 323 can drive the movable ring 321 to move up and down in the vertical direction, thereby completing the unfolding of the garbage bag and the recycling action of the unfolding mechanism 320.

[0045] In this embodiment, preferably, refer to Figures 4-7The second driving device 323 includes a pulley block, a connecting cable 3233, a rotating roller 3234, and a compression spring 3235. The pulley block includes a fixed pulley 3231 and a movable pulley 3232. The fixed pulley 3231 is pivotally connected to the movable cylinder 3112 with the largest diameter. The main function of the fixed pulley 3231 is to change the direction of movement of the connecting cable 3233 and to enable the connecting cable 3233 to effectively transmit force. The movable pulley 3232 can be connected to the movable ring 321 by a connector or directly welded to the movable ring 321. The function of the movable pulley 3232 is to change the relative distance between the fixed pulley 3231 and the movable pulley 3232 through the pulley system. The driving force is transmitted to the movable ring 321, causing it to move downwards. One end of the connecting cable 3233 is fixed to the inner wall of the movable cylinder 3112 with the largest diameter, ensuring that the connecting cable 3233 will not fall off during use. The other end of the connecting cable 3233 passes sequentially around the movable pulley 3232, the fixed pulley 3231, and the rotating roller 3234, and is wound up in the rotating roller 3234. The rotating roller 3234 drives the movable pulley 3232 to move by winding or releasing the connecting cable 3233. One end of the compression spring 3235 is connected to the inner bottom wall of the movable cylinder 3112 with the largest diameter, and the other end of the compression spring 3235 is connected to the movable ring 321. The initial state of the compression spring 3235 is the uncompressed state, i.e., the naturally extended state. At this time, the compression spring 3235 is not subjected to external force and is at its longest length, which can push the movable ring 321 upwards, so that the movable ring 321 drives the first support rod 3221 to the contracted state of the opening mechanism 320.

[0046] Indicatively, when the garbage bag needs to be opened, the rotating roller 3234 rotates to tighten the connecting cable 3233. As the connecting cable 3233 passes over the movable pulley 3232 and the fixed pulley 3231, it shortens the relative distance between them, pulling the movable pulley 3232 and its connected movable ring 321 downwards, overcoming the elastic force of the compression spring 3235. During the descent of the movable ring 321, the support rod assembly 322 unfolds, opening the garbage bag. The compression spring 3235 is further compressed, storing elastic potential energy, while simultaneously providing a buffer for the descent of the movable ring 321, preventing impact from excessive speed. After the opening task is completed, the rotating roller 3234 reverses its rotation, releasing the connecting cable 3233. The elastic force of the compression spring 3235 pushes the movable ring 321 upwards, while the tension of the connecting cable 3233 decreases, causing the movable ring 321 to rise and pull the support rod assembly 322 to retract, awaiting the next opening operation.

[0047] Indicatively, when the bag-holding device 300 is placed in the receiving groove 210, the opening mechanism 320 opens and is concealed in the lid 200 with minimal thickness. When the bag-holding task is to be performed, the opening mechanism 320 retracts and extends into the garbage bag with a narrow width. Then, following the extension and retraction of the telescopic mechanism 310, the opening device is gradually opened to fully unfold the garbage bag. After the garbage bag unfolding task is completed, the opening device retracts to prevent scratching the garbage bag. At the same time, the upper part of the opening device returns to the lid 200, and then the opening device is opened again and placed in the receiving groove 210. This cycle is repeated until the next bag-holding task is performed.

[0048] In this embodiment, preferably, refer to Figure 3 and Figure 10 Multiple movable cylinders 3112 have a through groove 3113 extending vertically on the same side. The movable ring 321 passes through the through groove 3113 and connects with the movable pulley 3232, providing a spatial path for the connection between the movable ring 321 and the movable pulley 3232, and also limiting the swaying of the movable ring 321 in the horizontal direction, thus enhancing the stability of the overall structure.

[0049] In this embodiment, preferably, refer to Figure 4 and Figure 6 The top surface of the bucket lid 200 is equipped with a control box 220 for easy operation by the user. The control box 220 has a cavity 221, which provides space for the rotating roller 3234 and other related control components. The rotating roller 3234 is located in the cavity 221 and is pivotally connected to the inner wall of the control box 220. The rotating roller 3234 can be driven by electric or manual means. As an illustration, the rotating roller 3234 is connected to a rotary motor.

[0050] In this embodiment, preferably, refer to Figure 4 and Figure 6 The bin body 100 includes an inner cylinder 110 and an outer cylinder 120. The inner cylinder 110 is movably fitted inside the outer cylinder 120. The inner cylinder 110 is used to fit the garbage bag for easy disassembly and cleaning. Garbage bag hook devices 130 are provided on opposite sides of the outer wall of the outer cylinder 120 for fixing the handle of the garbage bag. The garbage bag hook device 130 can be designed as a hook, with one end fixed to the outer wall of the outer cylinder 120 and the other end bent downward to hook the handle of the garbage bag, so as to support the garbage bag when the bag supporting device 300 unfolds the garbage bag.

[0051] In this embodiment, preferably, refer to Figure 2 The lid 200 is pivotally connected to the outer cylinder 120, allowing the lid 200 to rotate around the pivot axis to open and close the lid 200. The outer cylinder 120 is equipped with a foot-operated lid opening device 140, which typically includes components such as a pedal, a connecting rod, and a return spring, for driving the lid 200 to rotate around the pivot axis to open the lid.

[0052] In this embodiment, preferably, a garbage bag fixing device is provided at the bottom of the inner cylinder 110. The garbage bag fixing device includes multiple adhesive stickers. The adhesive side of the adhesive stickers faces upward to stick the unfolded garbage bag and prevent the garbage bag from shifting during use. The adhesive stickers can be disposable consumables. Multiple layers of adhesive stickers overlap. Each time the garbage bag is replaced, when the garbage bag is lifted, the top layer of adhesive stickers will detach from the garbage bag fixing device along with the garbage bag.

[0053] Indicatively, when using a trash can with an easy-to-use trash bag, the user first tears off a trash bag and unfolds it slightly. After placing it above the opening of the can body 100, the user hangs the bag handle on the trash bag hook devices 130 on both sides of the can body 100, closes the lid 200, and presses the bag-adding button on the control box 220 of the lid 200. The bag-opening component then opens the trash bag. After bagging, the user can dispose of trash normally. Because the trash bag is fully opened, lighter items such as paper scraps and plastic bags can fall smoothly to the bottom of the can, preventing trash from accumulating near the bag opening or adhering to the unopened parts, effectively improving the trash can's efficiency. When the user needs to dispose of trash, simply step on the foot-operated lid-opening device 140. The lid 200 will automatically open under the action of the linkage mechanism. After disposing of trash, releasing the foot pedal will cause the lid 200 to slowly close, preventing odors from escaping. When the garbage bag is full and needs to be emptied, the adhesive sticker will automatically detach from the garbage bag fixing device and follow the old garbage bag when the garbage bag is lifted. The adhesive sticker consumables need to be replenished regularly.
