Description

Technical Field

[0001] This utility model relates to the field of waste recycling technology, and in particular to a sealed box for the harmless treatment of biological experimental waste. Background Technology

[0002] With the widespread application of genetically modified (GM) technology in agriculture, laboratory-scale GM crop research is increasing. In agricultural genetic engineering research, cherry tomato GM experiments often generate waste containing recombinant DNA, resistance gene vectors, and GM plant debris, which pose biosafety risks. Improper handling could lead to environmental genetic pollution or biosafety hazards. Currently, waste generated during biological experiments needs to be placed in sealed containers and ultimately undergo harmless treatment.

[0003] Traditional sealed containers typically employ a single-cavity design, failing to physically separate solid waste (such as plant debris and petri dishes), liquid waste (such as DNA-containing culture media and buffer solutions), and sharps (such as inoculation needles and broken glass). Mixing different types of waste increases the risk of cross-contamination. Furthermore, existing waste bins for storage are mostly flip-top designs, where a press controls the opening and closing of the lid along one side for waste disposal. Since biological laboratory waste often contains various microorganisms, the flip-top design generates significant airflow when the lid is turned, causing these microorganisms to escape from the bin and into the external space, compromising operator safety.

[0004] In view of this, it is necessary to design a sealed container for the harmless treatment of biological experimental waste in order to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a sealed biological experimental waste harmless treatment box that can meet the needs of zoned treatment of various types of waste, avoid the risk of the spread of miscellaneous bacteria during the waste disposal process, and is easy to operate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A sealed container for the harmless treatment of biological laboratory waste, comprising: The box body has multiple cavities with open tops, and the lower part of each cavity has an opening. A placement box is installed inside the box, and a disposal port for disposing of waste is provided on the upper part of the side of the placement box away from the center of the box. A drive mechanism is provided on the box body and located below the placement box. The control end of the drive mechanism extends out of the box body through an opening, so that under the action of the drive mechanism, the placement box moves vertically along the cavity and switches between a placement state in which the placement port is exposed in the box body and a closed state in which the placement port is placed inside the box body.

[0007] As a further improvement of this utility model, the diameter of the top surface of the placement box is larger than the diameter of the top of the cavity.

[0008] As a further improvement of this utility model, the top of the placement box is also provided with a sealing ring to improve the sealing performance between the top surface of the placement box and the top of the cavity.

[0009] As a further improvement of this utility model, it also includes a guide mechanism for improving the stability of the placement box movement. The guide mechanism includes a vertical groove disposed on the side wall of the cavity and a corresponding slider disposed on the placement box.

[0010] As a further improvement of this utility model, the driving mechanism is a lever structure, including a rod that is rotatably connected to the box body in the middle, a pedal disposed at one end of the rod extending out of the box body, and an abutting ball disposed at the other end of the rod body.

[0011] As a further improvement of this utility model, the connection point between the rod and the box is located at the opening of the box.

[0012] As a further improvement of this utility model, the diameter of the contact ball is greater than the height of the rod.

[0013] As a further improvement of this utility model, the pedal is provided with anti-slip texture.

[0014] As a further improvement of this utility model, the top surface of the placement box is provided with a handle to facilitate the removal of the placement box from the box body.

[0015] As a further improvement of this utility model, a marking area is also provided on the top surface of the placement box.

[0016] The beneficial effects of this utility model are: 1. This utility model sets the disposal opening on the upper part of the placement box away from the center of the box body, and uses a drive mechanism set at the bottom of the box body to control the up and down movement of the placement box, so that the placement box can switch between a placement state in which the disposal opening is exposed to facilitate waste disposal and a closed state in which the disposal opening is placed inside the box body. Compared with the existing flip-top waste bins, the sealed box setting, which allows the disposal opening to move up and down with the placement box for waste disposal, can avoid the risk of large airflow generated when the lid is flipped, which would cause bacteria inside the box to escape into the surrounding space outside the box body and affect the safety of the operator.

[0017] 2. This utility model utilizes a bottom drive mechanism to control the vertical lifting of the placement box. When disposing of waste, the bottom drive mechanism raises the placement box a certain distance, eliminating the need for operators to bend over or touch the box with their hands. This makes operation simpler and avoids contamination of the box surface with genetically modified DNA, culture medium residues, or chemical reagents from hands.

[0018] 3. This utility model, by setting up multiple placement boxes, can achieve separate areas for solid, liquid, and sharps waste, thus blocking the risk of cross-contamination and spread of genetically modified components. Furthermore, the separate design of the placement boxes from the main body facilitates the subsequent removal of the entire placement box for direct placement in a high-temperature, high-pressure sterilizer or chemical treatment facility for harmless disposal.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0027] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0028] Please see Figures 1-3 As shown, this utility model provides a sealed box for the harmless treatment of biological experimental waste, comprising: The box body 10 is provided with a plurality of cavities 11 with open tops, and the lower part of each cavity 11 is provided with an opening 12. A placement box 20 is disposed inside the box body 10, and a disposal port 21 for disposing of waste is provided on the upper part of the side of the placement box 20 away from the center of the box body 10. A drive mechanism is provided on the housing 10 and located below the placement box 20. The control end of the drive mechanism extends outside the housing 10 through the opening 12, so that under the action of the drive mechanism, the placement box 20 moves vertically along the cavity 11 to switch between a placement state in which the placement port 21 is exposed in the housing 10 and a closed state in which the placement port 21 is placed inside the housing 10.

[0029] Specifically, the cavities 11 are spaced apart on the housing 10. For example, the housing 10 has four cylindrical cavities 11, and the bottom portions of the four cavities 11 are connected to each other at the corresponding openings 12. Figure 3 ).

[0030] Specifically, the shape of the placement box 20 is adapted to the shape of the box body 10. In this example, the placement box 20 is also cylindrical.

[0031] The placement box 20 includes a cylindrical box body for placing waste and a cover plate 22 fixed to the top of the cylindrical box body. The diameter of the cover plate 22 is larger than the top diameter of the cavity 11, so that when the placement box 20 is initially closed, the cover plate 22 completely covers the top of the cavity 11 and seals the cavity 11, thus completing the sealing of the placement box 20.

[0032] For example, a sealing ring is also provided on the periphery of the bottom surface of the cover plate 22 to improve the sealing performance between the placement box 20 and the top of the cavity 11, so as to improve the sealing effect on the cavity 11.

[0033] For example, the dispensing port 21 is located below the cover plate 22.

[0034] For example, the top surface of the placement box 20 is provided with a handle 23 for easy removal of the placement box 20 from the box body 10 and a marking area 24. Taking a cherry tomato transgenic experiment as an example, the marking area 24 allows operators to mark each placement box 20 according to the type of waste generated in the experiment, such as solid plant residues, liquid culture medium, sharps consumables, etc., to form "solid area", "liquid area", "sharps area", etc., to achieve classified management and improve the compliance of experimental operations.

[0035] For example, it also includes a guide mechanism to improve the moving stability of the placement box 20, the guide mechanism including a vertical groove 31 disposed on the side wall of the cavity 11 and a corresponding slider 32 disposed on the placement box 20. Figure 4The guiding mechanism not only positions the placement box 20 during the placement of the box 20 into the cavity 11, but also prevents the placement box 20 from rotating or shifting during lifting and lowering, thus ensuring the stability of the placement port 21.

[0036] For example, such as Figure 5 As shown, the drive mechanism is a lever structure, including a rod 41 that is rotatably connected to the housing 10 via a hinge shaft 44, a pedal 42 located at one end of the rod 41 extending outside the housing 10, and an abutment ball 43 located at the other end of the rod 41. The connection point between the rod 41 and the housing 10 is located at the opening 12 of the housing 10. The diameter of the abutment ball 43 is greater than the height of the rod 41, and the pedal 42 is provided with anti-slip texture.

[0037] In the initial state, the placement box 20 is closed with the placement opening 21 placed inside the box body 10 under the action of gravity. At this time, the bottom of the placement box 20 abuts against the rod 41, causing the pedal 42 to rise. When waste needs to be disposed of, the operator steps on the pedal 42 of the destination placement box 20, causing the rod 41 to rotate around the hinge axis 44 and the abutment ball 43 to lift the placement box 20, so that the placement box 20 moves up along the cavity 11 until the disposal port 21 is exposed outside the box 10. After the waste is disposed of into the placement box 20, the operator releases the pedal 42, and the placement box 20 falls back to the initial state under the action of gravity. At this time, the disposal port 21 is located inside the cavity 11, and the sealing ring at the bottom of the cover plate 22 is tightly fitted with the top of the cavity 11 to complete the sealing of the cavity 11, so as to isolate the waste from the external environment. After the experiment, the placement box 20 can be removed from the box body 10 by vertically lifting the handle 23. Then, the placement box 20 can be placed in a high-temperature and high-pressure sterilizer or chemical treatment equipment for harmless treatment.

[0038] Since biological experimental waste has a relatively small self-weight, as the amount of waste in the placement box 20 increases, the lever structure of this utility model can meet the lifting and lowering adjustment needs of the placement box.

[0039] Regarding the adjustment of the lever structure, in this example, by controlling the size of opening 12, clearance space can be provided to fully meet the linkage requirements of the lever structure.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
