Description

Technical Field

[0001] This invention belongs to the technical field of garbage bag pullers, specifically relating to a portable rotary bag puller. Background Technology

[0002] Currently, garbage bags are widely used in daily life, found in almost every environment including homes, offices, and public places. They are usually sold and stored in roll form. Users need to individually remove the roll of garbage bags and place them into garbage cans or garbage collection containers.

[0003] However, most existing garbage bag removal methods involve directly placing the garbage bag roll inside a cabinet, drawer, or simple storage container, lacking effective limiting and protective structures. This easily leads to problems such as garbage bags scattering, accidentally slipping out, or dust entering due to exposed bag openings. Furthermore, some existing garbage bag storage devices are bulky, inconvenient for users to carry, and fail to meet the needs of various scenarios such as outdoor use and travel.

[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

[0005] In view of the technical problems mentioned in the background art, the purpose of this invention is to provide a portable rotary bag drawer to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a portable rotary bag dispenser, comprising an outer mounting cylinder and an inner mounting cylinder, both of which are cylindrical in shape. The outer mounting cylinder has an inner mounting cavity inside, the inner diameter of which is larger than the outer diameter of the inner mounting cylinder. The inner mounting cylinder is rotatably mounted in the inner mounting cavity. The inner mounting cylinder has a placement cavity inside, a first bag outlet is provided on the side wall of the inner mounting cylinder, and a second bag outlet corresponding to the first bag outlet is provided on the side wall of the outer mounting cylinder.

[0007] Furthermore, the upper end of the second outlet is provided with an arc-shaped limiting groove, and the upper end of the first outlet is provided with a limiting component. The limiting component is embedded in the limiting groove to limit the rotation position of the inner cylinder. One end of the limiting groove is provided with an opening recess, and the other end of the limiting groove is provided with a closing recess.

[0008] Furthermore, the second outlet has symmetrical positioning openings at its upper and lower ends, and these two positioning openings are correspondingly positioned with the upper and lower ends of the first outlet.

[0009] Furthermore, both the second outlet and the positioning opening have arc-shaped opening corners, and the upper and lower ends of the first outlet have arc-shaped opening edges.

[0010] Furthermore, the limiting component includes a limiting protrusion and a limiting connecting block. The upper end of the first outlet bag has an installation opening. The limiting protrusion is located on the front side of the installation opening, and the limiting connecting block is located on the rear side of the installation opening. The limiting connecting block is engaged with the limiting protrusion.

[0011] Furthermore, the limiting block has a mounting protrusion on one end surface facing the limiting protrusion, the mounting protrusion has a fixing buckle on its surface, and the inner surface of the limiting protrusion has a fixing groove that matches the fixing buckle. The mounting protrusion is embedded in the mounting opening, and the fixing buckle is fastened in the fixing groove, so that a firm engaging connection is formed between the limiting block and the limiting protrusion.

[0012] Furthermore, the upper end of the mounting outer cylinder is connected to a portable strap, and the upper surface of the mounting outer cylinder is provided with a strap slot. The lower end of the portable strap is provided with a strap clamp that is adapted to the strap slot. The upper end of the strap clamp is provided with a first fixing protrusion, and the lower end of the strap clamp is provided with a second fixing protrusion. The strap clamp is engaged in the strap slot. At the same time, the first fixing protrusion is engaged at the upper end of the strap slot, and the second fixing protrusion is engaged at the lower end of the strap slot.

[0013] Furthermore, the lower end of the inner cylinder is provided with an inner cylinder rotating part, which is located at the lower outer end of the outer cylinder. The outer side wall of the inner cylinder rotating part is provided with a plurality of friction ridges, which are arranged in a circular array on the outer side wall of the inner cylinder rotating part.

[0014] Furthermore, both the outer and inner mounting cylinders are made of paper material.

[0015] Furthermore, both the outer and inner mounting cylinders are made of plastic.

[0016] The present invention has the following advantages: The inner cavity of the outer cylinder is larger than the outer diameter of the inner cylinder. The inner cylinder can be rotatably installed within the inner cavity. The inner cylinder also has a placement cavity. A first bag outlet is located on the side wall of the inner cylinder, and a second bag outlet corresponding to the first bag outlet is located on the side wall of the outer cylinder. The portable rotary bag dispenser of the present invention, through the fitting and rotating structure of the outer and inner cylinders, enables convenient storage and retrieval of garbage bags. During use, simply rotating the inner cylinder to align the first and second bag outlets allows for easy bag retrieval. After use or when sealing, rotating the cylinder to misalign prevents dust from entering and garbage bags from accidentally slipping out, ensuring a clean and safe bag retrieval process. A limiting slot is provided at the upper end of the second bag outlet, which works in conjunction with a limiting component to create a clear open and closed state, preventing misoperation. It is convenient for users to carry and use outdoors. The structure is simple and compact, and the operation is flexible. Attached Figure Description

Detailed Implementation

[0024] like Figures 1 to 6As shown, a portable rotary bag dispenser includes an outer mounting cylinder 10 and an inner mounting cylinder 20, both of which are cylindrical. The outer mounting cylinder 10 has an inner mounting cavity 11, the inner diameter of which is larger than the outer diameter of the inner mounting cylinder 20. The inner mounting cylinder 20 is rotatably mounted in the inner mounting cavity 11. The inner mounting cylinder 20 has a placement cavity 21 for placing garbage bag rolls, and its sidewalls have openings... The outer mounting cylinder 10 has a first outlet 22 and a second outlet 12 corresponding to the first outlet 22 on its side wall. In use, the user first places the garbage bag roll into the inner cavity 21 of the inner mounting cylinder 20. When the inner mounting cylinder 20 rotates until the first outlet 22 and the second outlet 12 are aligned, the opening of the garbage bag is passed through the first outlet 22, and the opening can be pulled out through the second outlet 12, thus enabling normal extraction and use of the garbage bag. After use or to prevent accidental extraction of the garbage bag, the user simply rotates the inner mounting cylinder 20 to misalign the first outlet 22 and the second outlet 12, thus sealing the bag opening, preventing dust and scattering of the garbage bag, thereby improving overall safety and convenience. The inner cylinder 20 can not only be used to hold garbage bag rolls, but also to load paper towels, disposable gloves or other small items according to user needs, making the bag dispenser multi-purpose and convenient for users to carry and use outdoors. It has a simple and compact structure and flexible operation. The opening and closing of the garbage bag opening is controlled by rotation, which not only improves the convenience of using garbage bags, but also has good portability and multi-functionality.

[0025] In practical implementation, the upper end of the second outlet 12 is provided with an arc-shaped limiting groove 13, and the upper end of the first outlet 22 is provided with a limiting component 30. The limiting component 30 is embedded in the limiting groove 13 to limit the rotational position of the mounting inner cylinder 20. One end of the limiting groove 13 is provided with an opening recess 131, and the other end of the limiting groove 13 is provided with a closing recess 132. In use, when the user needs to remove the garbage bag, the mounting inner cylinder 20 can be rotated so that the limiting component 30 engages with the opening recess 131. At this time, the first outlet 22 and the second outlet 12 are aligned with each other, and the garbage bag can be smoothly passed through and removed. After use or when it is necessary to close, the user rotates the mounting inner cylinder 20 to the position where the limiting component 30 engages with the closing recess 132. The first outlet 22 and the second outlet 12 are offset, thereby closing the bag opening and preventing dust from entering or the garbage bag from accidentally slipping out. Through the above structural design, with the cooperation of the limiting slot 13 and the limiting component 30, not only can the opening and closing of the garbage bag extraction port be controlled, but the accuracy and stability of rotation positioning can also be improved through the locking structure, preventing the garbage bag from falling out due to accidental contact causing the inner cylinder to rotate during use, thereby further improving the practicality and safety of the device of the present invention.

[0026] In practical implementation, the second outlet 12 has symmetrically arranged positioning openings 121 at its upper and lower ends. These two positioning openings 121 correspond to the upper and lower ends of the first outlet 22. During use, when the inner cylinder 20 rotates until the first outlet 22 aligns with the second outlet 12, the upper and lower ends of the first outlet 22 engage with their respective positioning openings 121, achieving precise positioning of the outlet and making the garbage bag extraction more stable and reliable. After use, the user simply needs to continue rotating the inner cylinder 20 to offset the first outlet 22 from the second outlet 12 by the positioning openings 121, thus closing the bag and preventing dust from entering and the garbage bag from accidentally slipping out. Through this structural design, the positioning function of the positioning openings 121 not only improves the positioning accuracy of the outlet in both open and closed states, ensuring a smoother garbage bag extraction process, but also enhances the overall convenience and reliability of use.

[0027] In practical implementation, both the second outlet 12 and the positioning opening 121 have arc-shaped opening corners 122 at their edges, and the first outlet 22 has arc-shaped opening edges 221 at both its upper and lower ends. During use, the arc-shaped opening edges 221 of the first outlet 22 cooperate with the arc-shaped opening corners 122 of the second outlet 12 and the positioning opening 121 to provide guidance and transition, ensuring even force distribution on the garbage bag during extraction and preventing it from being torn or jammed. This guarantees the smoothness and reliability of the garbage bag extraction process. Through this structural design, utilizing the arc transition between the opening corners 122 and the opening edges 221 not only improves the smoothness of garbage bag extraction but also effectively avoids the risk of damage to the bag during repeated extractions, further enhancing the durability of the device and the user experience.

[0028] In practical implementation, the limiting component 30 includes a limiting protrusion 31 and a limiting connecting block 32. The upper end of the first outlet 22 has an installation opening 23. The limiting protrusion 31 is located on the front side of the installation opening 23, and the limiting connecting block 32 is located on the rear side of the installation opening 23. The limiting connecting block 32 and the limiting protrusion 31 are fixedly connected by a snap-fit ​​structure, making the limiting component 30 an integral fixing unit. In use, the limiting protrusion 31 is embedded in the limiting slot 13, and the shape of the limiting slot 13 guides the inner cylinder 20 to rotate to the designated position. When the user rotates the inner cylinder 20 until the first bag outlet 22 is aligned with the second bag outlet 12, the limiting protrusion 31 engages with the opening recess 131 to open and position the bag outlet; when rotated to the closed position, the limiting protrusion 31 engages with the closing recess 132 to close and position the bag outlet, thereby ensuring the stability of the garbage bag extraction port in both open and closed states.

[0029] In practical implementation, the limiting block 32 has a mounting protrusion 321 protruding from one end of the limiting protrusion 31. The mounting protrusion 321 has a fixing buckle 322 on its surface, and the inner surface of the limiting protrusion 31 has a fixing groove 311 that matches the fixing buckle 322. During assembly, the mounting protrusion 31 is engaged in the mounting opening 23, and the fixing buckle 322 is engaged in the fixing groove 311, forming a secure engaging connection between the limiting block 32 and the limiting protrusion 31. This structure is simple to design, easy to install, and stable and reliable, requiring no additional screws or fasteners for fixation. Through this structure, the engaging connection between the limiting block 32 and the limiting protrusion 31 not only ensures the stability of the component connection but also simplifies and simplifies the installation and disassembly process, improving the ease of manufacturing and maintenance of the device, and enhancing the reliability and safety of the bag-pulling device during use.

[0030] In practical implementation, the upper end of the mounting outer cylinder 10 is connected to a portable strap 14. The upper surface of the mounting outer cylinder 10 has a strap slot 15, and the lower end of the portable strap 14 has a strap locking part 141 adapted to the strap slot 15. The upper end of the strap locking part 141 has a first fixing protrusion 141a, and the lower end of the strap locking part 141 has a second fixing protrusion 141b. During assembly, the strap locking part 141 engages with the strap slot 15. Simultaneously, the first fixing protrusion 141a is engaged at the upper end of the strap slot 15, and the second fixing protrusion 141b is engaged at the lower end of the strap slot 15, thus ensuring a stable and reliable connection of the portable strap 14 to the upper end of the mounting outer cylinder 10. In use, the user can hold or suspend the entire rotary bag dispenser using the portable strap 14, making it easy to carry and store, especially suitable for outdoor environments or mobile scenarios. Through the above structural design, the portable tube 14 can be quickly assembled and disassembled, which not only ensures the stability of the connection, but also improves the portability and practicality of the bag puller.

[0031] In practical implementation, the lower end of the inner cylinder 20 is provided with an inner cylinder rotating part 24, which is located at the lower outer end of the outer cylinder 10. During use, the user can pinch or push the inner cylinder rotating part 24 with their fingers, thereby causing the inner cylinder 20 to rotate relative to the outer cylinder 10, switching the first outlet 22 and the second outlet 12 between open and closed positions. The inner cylinder rotating part 24 not only makes the rotation operation more convenient and effortless but also avoids direct contact between the user and the main body of the inner cylinder 20, reducing slippage caused by hand friction or sweat.

[0032] In practical implementation, the outer wall of the inner cylinder rotating part 24 is provided with a plurality of friction protrusions 241. These friction protrusions 241 are arranged in a circular array on the outer wall of the inner cylinder rotating part 24. During use, the user can contact and push the friction protrusions 241 with their fingers, thereby causing the inner cylinder 20 to rotate relative to the outer cylinder 10. Because the protruding structure of the friction protrusions 241 can effectively increase the friction between the finger and the inner cylinder rotating part 24, the smoothness and stability of the rotation operation can be ensured even when the hands are wet or sweaty.

[0033] In practical implementation, both the outer mounting cylinder 10 and the inner mounting cylinder 20 can be made of paper or plastic. When paper is used, the overall structure is lightweight, production costs are low, and the material is environmentally friendly and easy to recycle, making it particularly suitable for one-time or short-term use. When plastic is used, the structure is stronger, more wear-resistant, and can withstand frequent rotational operations, extending the device's lifespan. It also has good moisture-proof and stain-proof properties, making it suitable for long-term repeated use. Therefore, depending on different usage requirements and cost considerations, paper or plastic can be flexibly selected as the materials for the outer and inner mounting cylinders.

[0034] In summary, the outer cylinder 10 has an inner cavity 11, the inner diameter of which is larger than the outer diameter of the inner cylinder 20. The inner cylinder 20 is rotatably installed in the inner cavity 11. The inner cylinder 20 has a placement cavity 21. The side wall of the inner cylinder 20 has a first bag outlet 22, and the side wall of the outer cylinder 10 has a second bag outlet 12 corresponding to the first bag outlet 22. The portable rotary bag dispenser of the present invention achieves convenient storage and retrieval of garbage bags through the sleeve and rotational cooperation structure of the outer cylinder and the inner cylinder. When in use, simply rotate the inner cylinder to align the first and second bag outlets to smoothly remove the bag. After use or when sealing, rotating the misalignment can prevent dust from entering and garbage bags from accidentally slipping out, ensuring the cleanliness and safety of the bag removal process. The upper end of the second bag outlet has a limiting groove and works with a limiting component to form a clear open and closed state, avoiding misoperation. It is convenient for users to carry and use outdoors. The structure is simple and compact, and the operation is flexible.
