Description

Technical Field

[0001] This utility model relates to a trash can, specifically a medical waste can. Background Technology

[0002] Medical waste refers to waste generated by medical institutions during medical treatment, prevention, healthcare, and other related activities that possess direct or indirect infectiousness, toxicity, or other hazards. Specifically, it includes infectious, pathological, damaging, pharmaceutical, and chemical waste. This waste contains large amounts of bacteria and viruses and exhibits characteristics of spatial pollution, acute viral transmission, and latent transmission. If not properly managed and disposed of indiscriminately, allowing it to mix with household waste and spread into people's living environments, it will pollute the atmosphere, water sources, land, and flora and fauna, causing the spread of diseases.

[0003] Traditional medical waste bins have rotating lids that create a large flow of gas during disposal. This gas flow can easily spread aerosols containing pathogens from inside the bin to the outside, potentially leading to disease transmission. Neither manually nor foot-operated rotating lids can completely prevent this problem. Furthermore, the bag-packing process in traditional medical waste bins is flawed. After packing, the top of the bag may not be securely fastened, causing it to slip off the outer or inner wall of the bin during disposal. This necessitates repacking, increasing the risk of infection for healthcare workers.

[0004] Therefore, a medical waste bin that effectively prevents gas flow and reduces aerosol transmission, effectively prevents slippage of the garbage bag opening, reduces the spread of germs, effectively reduces contact, is easy to use, and provides high-efficiency protection has broad market prospects.

The rotating support plate and the rotating opening and closing spherical cover are an integral structure. The rotating opening and closing spherical cover is a quarter-spherical structure, and the outer diameter of the rotating opening and closing spherical cover matches the inner diameter of the outer spherical cover.

[0010] A medical waste bin includes a bin body, a bin body ring seat fixedly installed on the upper part of the bin body, a cover ring seat installed above the bin body ring seat via a rotating opening and closing shaft assembly, a double-layer spherical cover fixedly installed on the top of the cover ring seat, an opening and closing fitting cavity provided inside the double-layer spherical cover, a rotating opening and closing spherical cover movably installed inside the opening and closing fitting cavity, a pull rope installed on the end face of the rotating opening and closing spherical cover located in the opening and closing fitting cavity, a bottom box provided at the bottom of the bin body, a pull rope steering wheel installed inside the bottom box, the other end of the pull rope passing around the pull rope steering wheel and connected to one end of a rotating lever installed inside the bottom box, the other end of the rotating lever connected to a foot pedal provided on the side wall of the bottom box, an annular iron ring embedded in the top surface of the bin body ring seat, and a magnetic ring cooperating with the annular iron ring embedded in the bottom surface of the cover ring seat.

[0011] Preferably, the double-layer spherical mask is a quarter-sphere structure, the rotating opening and closing spherical mask is a quarter-sphere structure, the opening and closing sleeve cavity is a quarter-sphere groove structure, the groove width of the opening and closing sleeve cavity matches the thickness of the rotating opening and closing spherical mask, the center of the opening and closing sleeve cavity and the center of the rotating opening and closing spherical mask are the same center, and a gravity block is provided on the bottom outer edge of the rotating opening and closing spherical mask.

[0012] Preferably, the cover ring seat and the barrel ring seat are respectively provided with an upper through hole and a lower through hole for mounting the pull rope, a pull rope limiting ring is fixedly installed on the outside of the barrel, and a pull rope insertion hole is provided on the top surface of the bottom box.

[0015] Preferably, the side wall of the barrel is provided with a vent hole, and the inner side of the cover ring seat and the barrel ring seat are respectively provided with a loading port that communicates with the loading cavity inside the barrel.

[0016] This utility model has the following positive effects:

[0017] 1. This product adopts a spherical rotating opening and closing method. The rotating opening and closing spherical cover is fitted into the inner wall of the outer spherical cover or the opening and closing cavity. It provides two modes: manual opening at the top and foot-operated opening at the bottom. The upper part adopts a spherical rotating opening and closing method, and only the rotating opening and closing part of the spherical cover is rotated and opened, which effectively reduces the opening and closing working surface and effectively avoids a large amount of gas flow during the traditional opening and closing process, thus avoiding the spread of diseases caused by the diffusion of aerosols carrying pathogens.

[0018] 2. This product uses a combination of a ring-shaped iron ring and a magnetic ring to secure the garbage bag at the top opening. This effectively prevents slippage and avoids deep pulling during recycling, reducing contact between hands and the inner wall of the garbage bag. The magnetic attachment ensures a firm hold on the top of the garbage bag. When removing the garbage bag, the top cover can be removed entirely or the opening and closing mechanism can be rotated to separate the cover ring from the bin ring, facilitating bag replacement. This reduces the risk of airflow caused by large opening and closing during disposal.

[0019] 3. When the rotating spherical cover of this product is opened and closed manually, the opening and closing operation is carried out by rotating the spherical cover through the handle. The opening and closing speed can be controlled to reduce air flow. When the rotating spherical cover is opened and closed by foot pedal, the spherical cover is pulled by the pull rope, pull rope steering wheel, rotating lever and foot pedal to open it. The opening position is automatically closed by the action of spring and gravity block during the return process of the rotating spherical cover. At the same time, this product is designed with vent holes to facilitate the garbage bag to fit against the wall of the bin during the garbage bag packing process.

[0020] 4. The ring iron ring and magnetic ring of this product are inlaid or the ring iron ring is movably snapped into the mounting groove on the top of the ring seat of the bin. When the garbage bag needs to be recycled, the ring iron ring and magnetic ring are magnetically attracted to each other by lifting the upper cover as a whole. After lifting the ring iron ring to tighten the garbage bag opening, the ring iron ring is separated to collect the garbage bag. This method can effectively avoid the spread of aerosols and the spread of viruses during the garbage bag collection process. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] In the following description of the invention, it should be noted that the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. The term "connection" simply indicates a connection between devices and has no special meaning.

[0032] Example 1: As Figure 1 , 2 As shown in Figures 3, 4, and 5, a medical waste bin includes a bin body 1 and a bin body ring seat 3 fixedly installed on the upper part of the bin body 1. A cover ring seat 2 is movably installed above the bin body ring seat 3. An outer spherical cover 8 is fixedly installed on the top of the cover ring seat 2. A rotating and opening spherical cover 4 is fitted inside the outer spherical cover 8. An annular iron ring 11 is embedded in the top surface of the bin body ring seat 3, and a magnetic ring 10 that cooperates with the annular iron ring 11 is embedded in the bottom surface of the cover ring seat 2.

[0033] Specifically, in this embodiment, the lid ring seat 2 and the barrel ring seat 3 are connected in a separate, movable manner. The lid ring seat 2, the upper outer spherical cover 8, and the rotating opening and closing spherical cover 4 constitute the upper lid part, while the barrel ring seat 3 and the barrel 1 constitute the lower storage part. In this embodiment, the rotating opening and closing spherical cover 4 is opened and closed manually. The barrel ring seat 3 and the lid ring seat 2 are connected and installed by the mutual attraction of the annular iron ring 11 and the magnetic ring 10. During specific installation, the magnetic ring 10 can be fixedly embedded in the bottom surface of the lid ring seat 2, and the annular iron ring 11 can be fixedly installed in the top surface of the barrel ring seat 3, or a movable installation method can be used, where an annular placement groove is set on the top surface of the barrel ring seat 3 and the annular iron ring 11 is snapped into the annular placement groove. The rotating opening and closing spherical cover 4 performs spherical rotation on the inner wall of the outer spherical cover 8, which can effectively prevent gas flow.

[0034] The cover ring seat 2 is movably mounted above the barrel ring seat 3 via an annular iron ring 11 and a magnetic ring 10. The outer diameter of the cover ring seat 2 is equal to the outer diameter of the barrel ring seat 3. An opening and closing handle 5 is provided on the bottom outer edge of the rotating opening and closing spherical cover 4. The outer spherical cover 8 is a quarter-spherical structure. An annular support ring 7, which is integral with the bottom of the outer spherical cover 8, is installed on the top of the cover ring seat 2. The top surface of the annular support ring 7 is on the same plane as the surface where the center of the outer spherical cover 8 is located. A counterweight seat 12 is provided at the bottom of the barrel 1. A rotating support seat 6 is provided at the junction of the annular support ring 7 and the side of the outer spherical cover 8. A rotating shaft 9 is fixedly installed on the inner side of the rotating support seat 6. A rotating support plate 14 is fitted on the rotating shaft 9. The rotating support plate 14 is integral with the rotating opening and closing spherical cover 4. The rotating opening and closing spherical cover 4 is a quarter-spherical structure, and the outer diameter of the rotating opening and closing spherical cover 4 matches the inner diameter of the outer spherical cover 8. The barrel body 1 has a ventilation hole 13 on its side wall, and the inner sides of the cover ring seat 2 and the barrel ring seat 3 are respectively provided with a loading port 15 that communicates with the loading cavity 16 inside the barrel body 1.

[0035] Specifically, both the lid ring seat 2 and the barrel ring seat 3 are circular ring structures with equal inner and outer diameters. Similarly, the annular iron ring 11 and the magnetic ring 10 are circular ring structures with equal inner and outer diameters, or the inner diameter of the magnetic ring 10 is no greater than the inner diameter of the annular iron ring 11, and the outer diameter of the magnetic ring 10 is no greater than the outer diameter of the annular iron ring 11. After the lid ring seat 2 is vertically aligned with the top surface of the barrel ring seat 3, the annular iron ring 11 and the magnetic ring 10 magnetically attract each other, allowing the rotating spherical cover 4 and the outer spherical cover 8 on the upper part of the lid ring seat 2 to be correspondingly installed on the upper part of the barrel ring seat 3. Furthermore, when the opening and closing handle 5 is manually rotated and pulled open / closed, the position of the outer spherical cover 8 is fixed and corresponds to the barrel 1. When the rotating spherical cover 4 is mostly rotated into the outer spherical cover 8, the original closed position of the rotating spherical cover 4 becomes open, facilitating the disposal of waste.

[0036] Both the outer spherical cover 8 and the rotating opening and closing spherical cover 4 are semi-spherical structures capable of mutual rotation and cooperation. The rotating opening and closing spherical cover 4 can be hidden inside the outer spherical cover 8 when open. The annular support ring 7 provides bottom obstruction and support for the rotating opening and closing spherical cover 4 during rotation, and also provides reserved space for the setting of the rotation axis 9 on the center plane of both after the installation of the rotating support base 6. This ensures that during rotation operation, the rotating opening and closing spherical cover 4 can rotate and open along the axis of the center of the outer spherical cover 8, improving the accuracy of the product during operation. A counterweight 12 is provided at the bottom of the barrel 1 to enhance the stability of the bottom of the product, providing support for the stability of the product during the rotation operation of the rotating opening and closing spherical cover 4. The vent 13 can reduce the air retention in the loading cavity 16 during the garbage bag packing process, improving the fit between the garbage bag and the inner wall of the barrel 1 during the packing process.

[0037] In practical use, the garbage bag needs to be placed inside the bin body 1. Initially, the top of the bin body ring seat 3 is open. Take a garbage bag of suitable size, and fix the annular iron ring 11 to the top surface of the bin body ring seat 3 or place it in the corresponding mounting groove on the top of the bin body ring seat 3. After the garbage bag is placed inside, fold the bag opening back to cover the bin body ring seat 3, and then align the cover ring seat 2 with the bin body ring seat 3. After alignment, the annular iron ring 11 and the magnetic ring 10 attract each other, fixing the cover ring seat 2 to the upper part of the bin body ring seat 3. At the same time, use the bottom wall of the cover ring seat 2 to press and fix the folded-back position of the garbage bag opening.

[0038] When garbage needs to be disposed of, manually pull the opening and closing handle 5, and rotate the opening and closing spherical cover 4 around the rotation axis 9. The original closed position of the rotating opening and closing spherical cover 4 on the upper part of the cover ring seat 2 opens. After opening, the outer spherical cover 8 at the top of the cover ring seat 2 is in an open state. Garbage can be put into the disposal port 15 through this open position and fall into the garbage bag in the loading chamber 16. After disposal, reverse the operation to rotate the opening and closing spherical cover 4 to close the disposal port. During the opening and closing process, the rotating opening and closing spherical cover 4 always rotates around the rotation axis 9. By adopting the rotating opening and closing method, air flow is reduced, which can effectively prevent the diffusion of aerosols caused by airflow.

[0039] Example 2: As Figure 6 , 7As shown in Figures 8 and 9, a medical waste bin includes a bin body 1 and a bin body ring seat 3 fixedly installed on the upper part of the bin body 1. A cover ring seat 2 is installed above the bin body ring seat 3 via a rotating opening and closing shaft assembly 18. A double-layer spherical cover 17 is fixedly installed on the top of the cover ring seat 2. An opening and closing fitting cavity 23 is provided inside the double-layer spherical cover 17. A rotating opening and closing spherical cover 4 is movably installed inside the opening and closing fitting cavity 23. A pull rope is installed on the end face of the rotating opening and closing spherical cover 4 located inside the opening and closing fitting cavity 23. 19. A bottom box 20 is provided at the bottom of the barrel 1. A pull rope steering wheel 28 is installed in the bottom box 20. The other end of the pull rope 19 passes around the pull rope steering wheel 28 and is connected to one end of a rotating lever 31 installed in the bottom box 20. The other end of the rotating lever 31 is connected to a foot pedal 21 provided on the side wall of the bottom box 20. An annular iron ring 11 is embedded on the top surface of the barrel ring seat 3. A magnetic ring 10 that cooperates with the annular iron ring 11 is embedded on the bottom surface of the cover ring seat 2.

[0040] Specifically, in this embodiment, a rotating opening and closing shaft assembly 18 connects the cover ring seat 2 and the barrel ring seat 3 on the outer side. The double-layer spherical cover 17 adopts a double-layer structure and is fitted onto the rotating opening and closing spherical cover 4. When the rotating opening and closing spherical cover 4 rotates and opens, the portion entering the opening and closing fitting cavity 23 will not generate air fluctuations, further reducing gas flow during opening and closing. The upper end of the pull rope 19 is fitted into the opening and closing fitting cavity 23, and the middle part of the pull rope 19 is exposed on the rear outer wall of the barrel 1. The bottom of the pull rope 19 changes its output direction to upward through the pull rope deflector 28. The rotation of the rotating lever 31 causes the bottom end of the pull rope 19 to move upward, thereby driving the pull rope ring 35 in the opening and closing fitting cavity 23 to move, thereby causing the rotating opening and closing spherical cover 4 connected to the pull rope ring 35 to slide in the opening and closing fitting cavity 23, realizing the opening operation of the rotating opening and closing spherical cover 4. The annular iron ring 11 and the magnetic ring 10 adhere to each other after rotational docking. In specific installation, the magnet ring 10 can be fixedly embedded in the bottom surface of the cover ring seat 2, and the ring iron ring 11 can be fixedly installed on the top surface of the barrel ring seat 3, or the ring iron ring 11 can be installed in a movable installation method by setting an annular placement groove on the top surface of the barrel ring seat 3 and then snapping it into the annular placement groove.

[0041] The double-layer spherical mask 17 is a quarter-spherical structure, the rotating and opening spherical mask 4 is a quarter-spherical structure, and the opening and closing sleeve cavity 23 is a quarter-spherical groove structure. The groove width of the opening and closing sleeve cavity 23 matches the thickness of the rotating and opening spherical mask 4, and the center of the opening and closing sleeve cavity 23 and the center of the rotating and opening spherical mask 4 are the same. A gravity block 22 is provided on the outer edge of the bottom of the rotating and opening spherical mask 4. The cover ring seat 2 and the barrel ring seat 3 are respectively provided with an upper through hole 24 and a lower through hole 25 for mounting the pull rope 19. A pull rope limiting ring 26 is fixedly installed on the outside of the barrel 1, and a pull rope insertion hole is provided on the top surface of the bottom box 20.

[0042] During the closing operation, releasing the foot pedal 21 causes the rotating spherical cover 4 to automatically close under the action of the gravity block 22. The rotating spherical cover 4 can be fitted into the opening and closing fitting cavity 23 during operation. The gravity block 22 serves to limit rotation and automatically lower the cover to close it. The middle of the pull rope 19 is fixed by the pull rope limiting ring 26, the top is limited by the upper through hole 24 and the lower through hole 25, and the bottom enters the bottom box 20 through the pull rope insertion hole. Throughout the movement of the entire pull rope 19, it remains fixed in the fixed position.

[0043] A wheel axle 27 is fixedly installed on the upper part of the inner bottom surface of the bottom box 20. A pull rope steering wheel 28 is fitted onto the outside of the wheel axle 27. A ring seat shaft 29 is fixedly installed in the middle of the inner cavity of the bottom box 20. A rotating lever connecting ring 30 is fitted onto the outside of the ring seat shaft 29. The rotating lever connecting ring 30 and the rotating lever 31 are integrally structured. A spring 33 is fixedly installed on the bottom wall of the inner cavity of the bottom box 20, which cooperates with the foot pedal 21 or the rotating lever 31 at the inner end of the foot pedal 21. The bottom of the spring 33 is fixedly connected to the bottom wall of the inner cavity of the bottom box 20 through a fixing block 32. A pedal movable opening 34 that cooperates with the foot pedal 21 is opened on the side wall of the bottom box 20. A vent hole 13 is opened on the side wall of the barrel 1. The inner side of the cover ring seat 2 and the barrel ring seat 3 are respectively provided with a dispensing opening 15 that communicates with the loading cavity 16 inside the barrel 1.

[0044] The axle 27 provides central support for the pull rope steering wheel 28, and the ring seat axle 29 provides support for the installation of the rotating lever connecting ring 30. The outer end of the foot pedal 21 is exposed on the outside. The rotating lever 31 rotates around the ring seat axle 29. When the foot pedal 21 is pressed down, the end of the pull rope 19 moves upward at the upper end of the pull rope steering wheel 28. When the foot pedal 21 returns to its original position under the action of the spring 33, the end of the pull rope 19 moves downward at the upper end of the pull rope steering wheel 28, thereby realizing the opening and closing rotation operation of the rotating opening and closing spherical cover 4 in the opening and closing sleeve cavity 23.

[0045] In actual operation, the garbage bag first needs to be placed on the bin body 1. In the initial state, the outer sides of the bin body ring seat 3 and the lid ring seat 2 are connected by the rotating opening and closing shaft assembly 18 and are in the top open state. Take a garbage bag of appropriate size, and fix the annular iron ring 11 on the top surface of the bin body ring seat 3 or place it in the corresponding mounting groove set on the top of the bin body ring seat 3. After the garbage bag is placed, fold the bag opening back to cover the bin body ring seat 3. Then, the lid ring seat 2 rotates around the rotating opening and closing shaft assembly 18 and aligns with the bin body ring seat 3. After alignment, the annular iron ring 11 and the magnetic ring 10 attract each other, and the bottom wall of the lid ring seat 2 is used to press and fix the folded-back position of the garbage bag opening.

[0046] When garbage needs to be disposed of, step on foot pedal 21. Rotating lever 31 rotates around ring seat shaft 29. The distal end of rotating lever 31 drives the end of pull rope to move upward on the upper part of the inner side of pull rope steering wheel 28. Pull rope 19 drives rotating opening and closing spherical cover 4 to move within opening and closing sleeve cavity 23. After rotating opening and closing spherical cover 4 is mostly inside opening and closing sleeve cavity 23, disposal port 15 opens. Garbage can be put into disposal port 15 through this open position and fall into garbage bag in loading cavity 16. After disposal, release foot pedal 21. Under the action of spring 33 and gravity block 22, rotating opening and closing spherical cover 4 returns to the closed state. The use of rotating opening and closing cover reduces air flow and can effectively prevent the diffusion of aerosols caused by airflow.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
