Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a medical waste bin designed to prevent waste from drifting outwards. Background Technology

[0002] Foot-operated trash cans, with their advantages of contactless opening, convenient operation, good sealing, and excellent hygiene, are widely used in various indoor and outdoor scenarios such as homes, offices, commercial areas, and medical institutions, and are currently the mainstream trash collection equipment on the market. Their core working principle involves a foot-operated lever transmission structure that drives the top lid to rotate and open, eliminating the need for hand contact with the lid and effectively avoiding the risk of cross-infection of bacteria and germs. At the same time, the sealed structure when closed inhibits the spread of odors and prevents the breeding of mosquitoes and flies, meeting the basic daily cleaning and hygiene needs of the public.

[0003] The existing traditional foot-operated trash cans have a relatively fixed structural design, consisting of a bin body, a foot-operated transmission component, a flip-top lid, and a reset component. This design presents significant structural flaws during the opening process. When the user steps on the pedal, causing the flip-top lid to rotate rapidly around the hinge point, the lid compresses the air at the bin opening. Simultaneously, the sealed interior space of the bin quickly connects with the outside, creating an instantaneous pressure gradient difference between the inside and outside, generating directional convection airflow. This instantaneous airflow is fast and highly turbulent. Meanwhile, the trash cans typically collect low-density, lightweight waste such as tissue paper scraps, dust, plastic film, shredded paper, and hair, which have minimal weight and weak adhesion.

[0004] Under the impact of the convective airflow inside the bin, various lightweight wastes adhering to the inside and side walls are easily blown up and lifted by the airflow. Some of this lightweight waste overflows from the bin opening and scatters onto the ground, countertops, and other surrounding areas, causing not only a dirty and messy environment and secondary pollution, but also increasing the workload of cleaning staff and affecting the overall cleanliness of the scene. At the same time, the lifted lightweight dust, debris, and other impurities remain suspended in the air, spreading bacteria and odor molecules generated by the waste, continuously worsening the surrounding air quality. In scenarios with high environmental hygiene requirements, such as medical institutions and food offices, this can easily exacerbate the risk of germ transmission. Summary of the Invention

[0005] To address the aforementioned issues, this application discloses a medical waste bin designed to prevent waste from drifting outwards.

[0006] An anti-spillage medical waste bin includes a storage section, a sealing section, and a control section; the storage section is a cavity structure with an opening; a mounting bracket is provided on the side wall of the storage section; the sealing section is rotatably connected to the mounting bracket and can selectively seal the opening; one end of the control section is rotatably connected to the storage section, and the other end is rotatably connected to the sealing section to drive the sealing section to rotate; it also includes: A shielding part is located inside the storage part; the shielding part includes a shielding component, a transmission component, a connecting rod, and a driving block; the shielding component is rotatably connected to the storage part and can selectively block the opening; one end of the transmission component is connected to the shielding component, and the other end is fixedly connected to the driving component through the connecting rod; the mounting bracket is provided with a limiting groove; the sealing part is provided with a control groove; the limiting groove and the control groove partially overlap; the driving block is inserted into the interior of both the limiting groove and the control groove simultaneously.

[0007] Furthermore, the shielding component includes a filter screen, a shielding frame, and a driven shaft; the shielding frame and the driven shaft are fixedly connected; the shielding frame has a vent hole inside; the filter screen blocks the vent hole; and the driven shaft is connected to a transmission component.

[0008] Furthermore, the storage unit includes an outer barrel and an inner barrel; the inner barrel and the outer barrel are detachably connected.

[0009] Furthermore, the control unit includes a pedal and a lever; the middle part of the pedal is rotatably connected to the storage unit; one end of the pedal is enlarged, and the other end is rotatably connected to the lever; the end of the lever away from the pedal is rotatably connected to the sealing unit.

[0010] Furthermore, the transmission component includes a driven wheel and a driving wheel; the driven wheel meshes with the driving wheel; the transmission wheel is connected to a blocking component; and the driving wheel is fixedly connected to a connecting rod.

[0011] The beneficial effects of this invention are: The control unit drives the sealing section to open, while the blocking section still seals the opening of the storage section. A momentary airflow inside the bin blows up lightweight waste, but this waste is trapped inside the storage section by the blocking section. The blocking section then continues to rotate until one end of the control slot contacts the drive block, which, through a connecting rod and transmission component, drives the blocking component to rotate, thus removing the blockage from the storage section opening. At this point, the momentary airflow inside the bin disappears, and the blown-up lightweight waste gradually returns to its original position under gravity, preventing it from being blown out. This effectively suppresses the problem of lightweight waste such as paper scraps, dust, plastic film, and hair being blown up and scattered by airflow. It also prevents lightweight waste from overflowing from the bin opening and scattering onto the surrounding ground, completely solving the environmental mess caused by dust and waste spillage when the traditional trash can is opened. This significantly reduces the workload of subsequent manual secondary cleaning and continuously ensures the cleanliness of the usage environment.

[0012] It effectively avoids the suspension of light dust and garbage debris in the air, reduces the diffusion of bacteria and odor molecules attached to garbage into the surrounding air, eliminates the risk of cross-contamination of germs from garbage dust, and significantly improves the hygiene and protective performance of the garbage can. It is not only suitable for everyday civilian use in homes and offices, but also meets the high hygiene standards required in supermarkets, medical institutions, and food processing areas, making the product more widely applicable.

[0013] The optimized structure enables dust suppression and prevention, eliminating the need for additional complex electrical control components or independent dust removal accessories. The overall structure is simple, production costs are low, and assembly is convenient. At the same time, it does not affect the basic functions of the foot-operated trash can, such as contactless opening, odor prevention, and smooth opening and closing. The equipment is highly stable and durable.

[0014] While improving the user experience and hygiene performance, it effectively controls product production costs, possessing excellent practicality and market promotion value. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0021] like Figure 1-10 The illustrated medical waste bin for preventing spillage includes a storage section 1, a sealing section 2, and a control section 4. The storage section 1 is a cavity structure with an opening. A mounting bracket 14 is provided on the side wall of the storage section 1. The sealing section 2 is rotatably connected to the mounting bracket 14 and can selectively seal the opening. One end of the control section 4 is rotatably connected to the storage section 1, and the other end is rotatably connected to the sealing section 2 to drive the sealing section 2 to rotate. It also includes: The shielding part 3 is located inside the storage part 1. The shielding part 3 includes a shielding member, a transmission member, a connecting rod 35, and a drive block 36. The shielding member is rotatably connected to the storage part 1 and can selectively block the opening. One end of the transmission member is connected to the shielding member, and the other end is fixedly connected to the drive member through the connecting rod 35. The mounting bracket 14 is provided with a limiting groove 142. The sealing part 2 is provided with a control groove 23. The limiting groove 142 and the control groove 23 partially overlap. The drive block 36 is inserted into the interior of both the limiting groove 142 and the control groove 23.

[0022] The control unit 4 drives the sealing unit 2 to open. At this time, the blocking part 3 still blocks the opening of the storage unit 1. The instantaneous airflow inside the bin blows up light waste, but the light waste is blocked inside the storage unit 1 by the blocking part 3. Then the blocking part 3 continues to rotate until one end of the control groove 23 contacts the drive block 36, thereby driving the blocking part to rotate through the connecting rod 35 and the transmission component, so that the blocking part no longer blocks the opening of the storage unit 1. At this time, the instantaneous airflow inside the bin disappears, and the blown light waste gradually returns to its original position under the drive of gravity, thus preventing the light waste from being blown out. This fundamentally suppresses the problem of light waste such as paper scraps, dust, plastic film, and hair being blown up and scattered by the airflow inside the bin. It prevents light waste from overflowing from the bin opening and scattering onto the surrounding ground, completely solving the environmental mess caused by dust and garbage overflow when the traditional bin is opened, greatly reducing the workload of subsequent manual secondary cleaning, and continuously ensuring the cleanliness of the usage environment. It effectively avoids the suspension of light dust and garbage debris in the air, reduces the diffusion of bacteria and odor molecules attached to garbage into the surrounding air, eliminates the risk of cross-contamination of germs from garbage dust, and significantly improves the hygiene and protective performance of the garbage can. It is not only suitable for everyday civilian use in homes and offices, but also meets the high hygiene standards required in supermarkets, medical institutions, and food processing areas, making the product more widely applicable.

[0023] Specifically, the shielding components include a filter screen 31, a support frame 13, and a driven shaft 37; the support frame 13 and the driven shaft 37 are fixedly connected; the support frame 13 has a vent hole 121 inside; the filter screen 31 blocks the vent hole 121; and the driven shaft 37 is connected to a transmission component. The filter screen 31 has a porous mesh structure, which is permeable and breathable but has strong turbulence damping properties. When the vertical convective airflow generated by opening the trash can flows from the inside of the can to the opening, the high-speed airflow comes into contact with the filter screen 31 and is divided into multiple fine airflows by the mesh skeleton of the filter screen 31. At the same time, the mesh structure of the filter screen 31 will generate frictional resistance and obstruction resistance on the airflow, consume the kinetic energy of the airflow itself, significantly reduce the airflow rate, weaken the strong convection effect brought about by the instantaneous air pressure difference, and prevent the high-speed airflow from directly washing over the lightweight garbage accumulated at the bottom and side walls of the can. On the other hand, the filter screen 31 can disrupt the original concentrated and directional airflow, turning the regular high-speed airflow inside the bin into a disordered weak diffuse flow, eliminating the concentrated impact force of the airflow, and greatly reducing the lifting and blowing force of the airflow on lightweight waste such as paper scraps, dust, plastic film, and hair.

[0024] like Figure 1-10As shown, four blocking members are provided on the inner wall of the storage section 1; the multiple blocking members are arranged circumferentially around the axis of the storage section 1; the blocking members abut against each other to block the opening; the two ends of the driven shaft 37 are respectively provided with connecting members; adjacent driven shafts 37 are connected by connecting members. When the transmission member drives one blocking member to rotate, the driven shaft 37 drives other driven shafts 37 to rotate through the connecting members, thereby driving multiple blocking members to rotate simultaneously, thus exposing the opening.

[0025] Specifically, the connecting component is a bevel gear; adjacent bevel gears mesh with each other.

[0026] Furthermore, to prevent the blocking components from separating from each other, a magnetic attraction structure is provided on the side wall of the support frame 13. When the blocking components block the opening, the magnetic attraction structures on the support frame 13 attract each other, enhancing the stability of the connection.

[0027] like Figure 1-10 As shown, the transmission component includes a driven wheel 33 and a driving wheel 34; the driven wheel 33 and the driving wheel 34 mesh; the transmission wheel is connected to the blocking component; and the driving wheel 34 is fixedly connected to the connecting rod 35.

[0028] Furthermore, the diameter of the driving wheel 34 is a; the diameter of the driven wheel 33 is b, and a / b≥3.

[0029] like Figure 4-7 As shown, a first rotating shaft 141 is provided on the side wall of the mounting bracket 14; the first rotating shaft 141 is inserted into the interior of the sealing part 2; both the limiting groove 142 and the control groove 23 are arc-shaped grooves; the centers of the limiting groove 142 and the control groove 23 coincide with the axis of the first rotating shaft 141. Figure 7 For example, at this time, the sealing part 2 opens, and one end of the control groove 23 contacts the drive block 36. Then the sealing part 2 continues to rotate, causing the drive block 36 to slide along the limiting groove 142. The connecting rod 35 and the transmission component drive the blocking component to rotate, so that the blocking component no longer blocks the opening of the storage part 1.

[0030] like Figure 1-10 As shown, the sealing part 2 is a bucket lid. A first rotating frame 21 and a second rotating frame 22 are fixedly connected to one side of the sealing part 2. The first rotating frame 21 is rotatably connected to the mounting frame 14 of the equipment, forming the main rotation fulcrum of the sealing part 2, ensuring that the sealing part 2 can be stably flipped open and closed. The second rotating frame 22 is rotatably connected to the top of the pull rod 42 of the control part 4, and is used to receive the transmission force of the pull rod 42. It works with the first rotating frame 21 to complete the linkage transmission, realize the precise linkage between the control part 4 and the sealing part 2, ensure that the foot pedal transmission structure responds sensitively, opens and closes smoothly, and has no jamming or sticking, ensuring the long-term stable operation of the equipment.

[0031] like Figure 1-10As shown, the storage unit 1 includes an outer barrel 11 and an inner barrel 12, with the inner barrel 12 nested inside the outer barrel 11. The outer barrel 11 and the inner barrel 12 form a protective and buffering double-layer structure, which can directly receive various types of waste through the inner barrel 12 to complete waste collection; at the same time, the outer barrel 11 can provide external protection for the inner barrel 12, improving the overall structural strength, while a reserved gap is formed between the inner and outer barrels 11.

[0032] The inner barrel 12 and the outer barrel 11 are detachably connected. This detachable connection allows staff to easily remove the inner barrel 12 from the outer barrel 11 to perform maintenance tasks such as garbage dumping, barrel cleaning, and internal debris removal. This eliminates the need for complete disassembly of the equipment, making operation convenient and effectively improving the ease of equipment maintenance.

[0033] A compartment door 111 is provided on the side wall of the outer tub 11, and the compartment door 111 is detachably connected to the outer tub 11. The compartment door 111 is positioned to correspond to the gap between the inner and outer tubs 11. By opening the compartment door 111, the inner tub 12 can be quickly removed from or placed into the outer tub 11.

[0034] The height of the inner bin 12 is greater than its width, and the height of the inner bin 12 is also greater than its length. By limiting the height of the inner bin 12 to a vertical structure that is greater than its length and width, the inner bin 12 forms a vertically extending storage cavity. This increases the vertical garbage storage capacity of the trash can, allowing it to hold more household waste while occupying the same floor area, thus improving space utilization.

[0035] like Figure 1-10 As shown, a support frame 13 is fixedly connected inside the storage section 1, and the support frame 13 is rotatably connected to the shielding component. The support frame 13 is positioned above the gap between the inner barrel 12 and the outer barrel 11, so that the support frame 13 completely seals the gap between the outer barrel 11 and the inner barrel 12, effectively preventing small and lightweight waste such as paper scraps, dust, and hair from falling into the gap between the inner and outer barrels 11, preventing dust and dirt accumulation in the gap. At the same time, the support frame 13 can seal and protect the gap structure, preventing external airflow from entering the gap.

[0036] Preferably, at least two through holes are provided on the side wall of the inner barrel 12, and the multiple through holes are evenly distributed on the surface of the side wall of the inner barrel 12. When a garbage bag is placed in the inner barrel 12, the air between the garbage bag and the inner barrel 12 is discharged through the through holes, so that the garbage bag can completely fit against the inner wall of the inner barrel 12.

[0037] Preferably, a drain pipe 122 is fixedly installed at the bottom of the inner tub 12, and the drain pipe 122 communicates with the interior of the inner tub 12. When cleaning the inner tub 12, the wastewater in the inner tub 12 can be discharged through the drain pipe 122.

[0038] Furthermore, a drain valve is connected in series on the drain pipe 122. The drain valve can control the on / off state of the drain pipe 122. During daily use, the drain valve is closed to maintain the sealing of the tank. When drainage or cleaning is required, the drain valve is opened to complete the discharge of sewage.

[0039] like Figure 1-10 As shown, a support frame 13 is fixedly installed on the inner bottom surface of the outer barrel 11, and the bottom of the inner barrel 12 abuts against the top of the support frame 13 for support. The support frame 13 can raise the inner barrel 12 as a whole.

[0040] Preferably, the height of the support frame 13 is greater than the length of the drain pipe 122, ensuring that the drain pipe 122 is completely suspended in the gap between the bottom of the inner and outer barrels 11, avoiding the drain pipe 122 from being squeezed, bent, or blocked, ensuring the smooth and stable drainage structure, and effectively extending the service life of the drainage components.

[0041] like Figure 1-10 As shown, the control unit 4 is used to realize the functions of foot pedal transmission and drive the opening and closing of the sealing part 2. The control unit includes a pedal 41 and a pull rod 42. The middle part of the pedal 41 is rotatably connected to the storage part 1, forming a lever transmission structure with the middle part of the pedal 41 as the fulcrum. One end of the pedal 41 is set as an enlarged structure, which increases the foot pedal contact area, improves the user's foot pedaling comfort, and increases the force-bearing area to prevent slipping. The other end of the pedal 41 away from the enlarged end is rotatably connected to the bottom end of the pull rod 42, and the top end of the pull rod 42 away from the pedal 41 is rotatably connected to the sealing part 2. When the pedal 41 is stepped on, the lever principle drives the pull rod 42 to rise and fall vertically, thereby pulling the sealing part 2 to complete the flipping opening and closing, realizing contactless opening operation. The transmission structure is simple and the operation is stable.

[0042] A rotating frame 15 is fixedly installed at the end of the storage section 1 away from the sealing section 2. The pedal 41 is rotatably hinged to the rotating frame 15. The independently installed rotating frame 15 provides a stable rotation fulcrum for the pedal 41. Compared with the method of directly hinged to the barrel, it can reduce barrel wear, improve the stability and durability of the transmission structure, and facilitate the disassembly and maintenance of the pedal 41.

[0043] Furthermore, the bottom of the outer barrel 11 is provided with a recessed mounting groove, and the pedal 41 is arranged inside the mounting groove and performs rotation within the mounting groove. The mounting groove can hide the pedal 41, avoiding the pedal 41 from being exposed and protruding, reducing the space occupied, while also protecting the pedal 41 from external impacts and squeezing that could damage the transmission structure, thus improving the overall aesthetics and structural safety of the equipment.

[0044] The above are merely specific embodiments of this application. Under the guidance of the above teachings, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of this application, and the scope of protection of this application should be determined by the scope of the claims.
