TECHNICAL FIELD
[0001] The utility model relates to the field of biological safety garbage treatment, especially to a biological safety medical waste barrel. BACKGROUND
[0002] Biological safety garbage is mostly composed of medical waste containing microorganisms, viruses and toxins, which can directly threaten human health and also cause harm to animals and the environment. Blood, body fluids, pathological garbage, test garbage, contaminated laboratory work materials, tissues and organs, used syringes, animal excrement and the like all belong to the category of biological hazard garbage. For medical institutions, laboratories and disease control centers and the like, biological safety garbage generated after biological experiments or medical operations needs to be properly treated to prevent cross-infection and environmental pollution. Currently, problems existing in the field of biological safety garbage treatment include complex garbage treatment process operation, low garbage treatment efficiency, safety hazards in garbage treatment and the like. Currently, most of the recycling of biological safety garbage is performed by garbage collection workers who extract the internal plastic bags from the garbage cans for recycling, which can easily pollute the laboratory and cause harm to the garbage collection workers, thus causing occupational exposure. For example, patent application CN212449047U discloses a convenient knotting garbage can, which is capable of tightening the opening of the garbage bag by pressing the pressing plate on the side of the top cover, inserting the fixed shaft at the connection between the top cover and the barrel body into the slide, driving the fixed block three at the bottom of the top cover to expand the connecting rod, gathering the expanded connecting rod to the center, and tightening the opening of the garbage bag with the connecting rod. However, the garbage bag cannot be automatically tightened and extracted. When manually processing biological safety garbage, it is easy to cause the risk of aerosol when sealing the garbage bag.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.
[0028] Example 1
[0029] This embodiment provides a biosafety medical waste bin, such as Figure 1 As shown, the container includes a lid 1 and a body 2. The lid 1 is equipped with a sterilization device 3, and the body 2 is equipped with a weighing device 4, a sealing device 5, a convenient removal device 6, a garbage bag adsorption device 7, a pedal 8, a lid opening and closing device 9, and an emergency stop button 10.
[0030] like Figure 3 As shown, the lid 1 and the body 2 are connected by a rotating shaft 11, on which a rotating gear 1101 is provided.
[0031] like Figure 2 As shown, a side door 201 is provided on one side of the bin body 2. The dimensions of the side door 201 are three-quarters of the width and height of the bin (garbage bin specifications: 120L, length 55cm, width 47cm, height 93cm). The side door 201 has a sealing strip for leak prevention and is connected to the bin body 2 by a hinge. A spring return device 2011 is provided on the side door 201. Universal wheels 203 are provided at the four corners of the bottom of the bin body 2. Fixtures 2031 are provided on the universal wheels 203 to restrict the rotation of the universal wheels 203, thereby fixing the garbage bin in a set position. Multiple limiting blocks 202 are provided on the inner wall of the bin body 2. The front end of the limiting block 202 is a raised trapezoidal structure, the height of which is less than the width of the cable tie. The specific structure of the limiting block is as follows. Figure 4 As shown.
[0032] The sterilization device 3 is an ultraviolet disinfection lamp that can be turned on manually or at a set time to kill bacteria and viruses.
[0033] The weighing device includes a weight sensor 401 and a digital display screen 402. The weight sensor 401 is located at the bottom of the barrel body 2, and the digital display screen 402 is located at the top of the barrel lid 1. Figure 2 As shown, the weight sensor 401 and the digital display screen 402 are connected by a circuit.
[0034] The sealing device 5 is installed on the inner wall of the barrel body 2, and includes a clamp 501 and a pushing mechanism 502, which are horizontally and tightly installed. The limiting block 202 is at the same height as the clamp 501 and the pushing mechanism 502. The structure of the clamp 501 is as follows: Figure 6 As shown, the clamp 501 includes a clamping plate 5011 and a spring 5012, and the surface of the clamping plate 5011 is provided with anti-slip strips. The structure of the pushing mechanism 502 is as follows. Figure 6 As shown, it includes a servo motor and a roller 5021. The pushing mechanism 502 uses the servo motor to drive the roller 5021 to push the cable tie and thus tighten it.
[0035] like Figure 7 and Figure 8 As shown, the convenient removal device 6 includes a chassis 601, a slide rail 602, and a cylinder 603. The chassis 601 is a rectangular platform slightly smaller than the bottom of the bin. A baffle 6011 is provided on one side of the chassis 601 to secure the garbage bag. The surface of the chassis 601 is provided with anti-slip strips, and the baffle on the edge of the chassis 601 is made of corrosion-resistant material with a silver ion antibacterial coating. An aluminum alloy slide rail 602 is installed at the bottom of the bin body 2 for smooth pushing. The chassis 601 and the cylinder 603 are connected by a pneumatic piston 604, and the slide rail 602 is welded to the chassis 601. Ventilation holes 6012 are provided on the chassis 601.
[0036] like Figure 7 As shown, the garbage bag adsorption device 7 is located at the bottom of the inner side of the bin body 2. The garbage bag adsorption device 7 is a centrifugal fan, and the ventilation hole 6012 matches the size of the air inlet of the centrifugal fan.
[0037] The pedals 8 are located on the outer wall of the bin body 2 and include a lid opening and closing pedal 801, a sealing pedal 802, a convenient removal pedal 803, and a garbage bag suction pedal 804. The lid opening and closing pedal 801 is connected to the lid opening and closing device 9, the sealing pedal 802 is connected to the sealing device 5, the convenient removal pedal 803 is connected to the convenient removal device 6, and the garbage bag suction pedal 804 is connected to the garbage bag suction device 7. The emergency stop button 10 is located on the outer wall of the bin body 2 and is connected to the sealing device 5, the convenient removal device 6, the garbage bag suction device 7, and the lid opening and closing device 9 via electrical circuit.
[0038] As shown in Figure 3 The bucket cover opening and closing device 9 includes a motor and a transmission gear 901, which matches with a rotating gear 1101 arranged on the rotating shaft 11. When the operator steps on the bucket cover opening and closing pedal 801, the bucket cover opening and closing device 9 drives the transmission gear through the motor, the transmission gear drives the rotating gear on the rotating shaft to rotate, thereby realizing the opening of the bucket cover 1. When the operator steps on the bucket cover opening and closing pedal 801 again, the motor reverses, thereby realizing the closing of the bucket cover 1.
[0039] The top view of the biological safety medical waste bucket according to the present application is shown in Figure 5 During the use of the biological safety medical waste bucket, the operator passes the strip-shaped end of the cable tie through the buckle, clamps the buckle through the clamping plate 5011 and the spring 5012 to prevent the buckle from sliding during the tightening of the cable tie, and places the cable tie in the limiting block 202 on the pushing mechanism 502 and the garbage can wall.
[0040] The operator manually places the garbage bag into the garbage can to ensure that the bag opening is aligned with the can opening. In this embodiment, a centrifugal fan with a power of 50W to 100W is installed in the can. When the operator steps on the garbage bag adsorption pedal 804, the centrifugal fan generates a strong airflow, which rapidly expands the garbage bag through the ventilation hole 6012 and adsorbs it on the can wall, avoiding wrinkles and gaps.
[0041] When the garbage weight on the digital display screen 402 reaches the preset value, the operator steps on the cable tie pedal 802, and the pushing mechanism 502 is driven by the servo motor to push the cable tie and tighten the cable tie. The servo motor drives the roller 5021 to drive the cable tie to gradually pass through the buckle at a constant speed, thereby tightening the cable tie and gradually tightening the garbage bag opening. During the tightening of the cable tie, the cable tie gradually detaches from the limiting block 202. When the cable tie is completed, the operator steps on the cable tie pedal 802 again, and the servo motor stops running.
[0042] When the operator steps on the convenient removal pedal 803, the convenient removal device 6 moves the chassis 601 along the slide rail 602 towards the side door 201 by the pneumatic piston 604 of the air cylinder 603, the cable tie buckle is detached from the clamp 501, and the garbage bag is pushed out through the side door 201. When the operator removes the garbage bag from the chassis 601, the side door 201 is reset by the spring reset device 2011.
[0043] When a special situation occurs, the operator can press the emergency stop button 10 to immediately stop all functions and actions of the cable tie device 5, the convenient removal device 6, the garbage bag adsorption device 7, and the bucket cover opening and closing device 9, ensuring that the operator can take action quickly in an emergency.
[0044] The preferred embodiments of the present application are described in detail above. It should be understood that those skilled in the art can make many modifications and changes without creative labor based on the concept of the present application. Therefore, any technical solutions obtained by logical analysis, reasoning or limited experiments based on the existing technology within the concept of the present application shall be within the protection scope defined by the claims.
