Description

Technical Field

[0001] This invention relates to the field of medical waste treatment technology, specifically to an intelligent device for disposing of narcotic and psychotropic drug containers and its control method. Background Technology

[0002] Medical waste disposal is a crucial part of the healthcare system. The safe disposal of containers for narcotic and psychotropic drugs is directly related to public safety and environmental protection. These containers include ampoules, vials, and infusion pumps. These drug containers are typically disposed of using specialized drug container disposal equipment.

[0003] In existing technologies, such equipment generally has different feeding channels to distinguish different types of containers, and uses a verification module to confirm the input containers and a weighing module to obtain weight data. Structurally, existing solutions mostly rely on a sliding base plate mechanism to support the containers, and a horizontal push rod assembly to push the containers from the weighing area into the crushing chamber for crushing, thus completing the entire destruction process. However, this feeding method requires manual judgment of the container type and selection of the corresponding feeding port, and relies on complex mechanical pushing actions to complete the feeding, resulting in a cumbersome operation process and the equipment being prone to jamming or wear failures during long-term operation. At the same time, the dust generated by crushing is easy to float and contaminate the detection elements, affecting the stable operation and maintenance convenience of the equipment.

[0004] Therefore, there is a need in the field for a new intelligent intelligent narcotic and psychotropic drug container handling device and its control method to solve the above problems. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, namely the cumbersome destruction process, complex mechanical structure and easy jamming of existing drug container destruction equipment, and the susceptibility of sensors to dust contamination.

[0006] In one aspect, the present invention provides an intelligent narcotic and psychotropic drug container handling device, comprising: The frame has a feeding port and a receiving cavity and a crushing cavity arranged vertically, the feeding port being connected to the receiving cavity; An identity recognition module, which is mounted on the rack, is used to identify the user's identity information; A container tilting device is disposed between the receiving cavity and the crushing cavity, and is used to put the container to be destroyed into the crushing cavity by tilting action; A weighing module, which is installed on the container tilting device, is used to detect the weight of the container to be destroyed; A visual recognition module, which is disposed in the accommodating cavity or on the container flipping device, is used to identify the type of container to be destroyed; A pulverizing device is disposed in the pulverizing chamber for pulverizing the containers to be destroyed in the pulverizing chamber.

[0007] In some optional embodiments, the container tilting device includes a tilting motor and a tilting plate. The tilting plate is used to carry the container to be destroyed. The weighing module is disposed on the tilting plate and is used to detect the weight of the container to be destroyed on the tilting plate. The tilting motor is disposed between the accommodating cavity and the crushing cavity. The output end of the tilting motor is connected to the tilting plate and can drive the tilting plate to switch between a horizontal state and a vertical state. When the flipping plate is in a horizontal position, the flipping plate isolates the receiving cavity and the crushing cavity; When the flipping plate switches from a horizontal to a vertical position, the container to be destroyed on the flipping plate falls from the flipping plate into the crushing chamber due to its own gravity.

[0008] In some optional embodiments, a high-pressure blowing device is provided between the receiving cavity and the crushing cavity or on the flipping plate, the high-pressure blowing device being configured to blow air onto the bearing surface of the flipping plate.

[0009] In some optional embodiments, the bearing surface of the flipping plate is formed with a plurality of parallel micron-sized grooves, and the groove direction of all the micron-sized grooves is the same as the falling direction of the container to be destroyed when the flipping plate is flipped.

[0010] In some optional embodiments, the output end of the flipping motor is connected to a gear, and a groove structure is provided on the frame, between the receiving cavity and the crushing cavity. A sealing plate is slidably disposed on the groove structure, and the sealing plate is connected to or formed with a rack that meshes with the gear. When the flipping plate switches from a horizontal state to a vertical state, the gear drives the rack to move and thus drives the sealing plate to slide out of the groove structure to isolate and seal the receiving cavity and the crushing cavity.

[0011] In some alternative embodiments, a settling airflow device is provided in the pulverizing chamber, the settling airflow device being configured to generate a downward airflow to prevent dust generated by the pulverizing device when pulverizing the container to be destroyed from floating to the surface.

[0012] In some optional embodiments, a limiting groove structure is provided on the frame, between the receiving cavity and the crushing cavity, the limiting groove structure is used to limit the protruding end of the sealing plate, and a first trigger switch and a second trigger switch are provided in the limiting groove structure. The first trigger switch can trigger the high-pressure blowing device, and the second trigger switch can trigger the settling airflow device. When the extended end of the sealing plate extends into the limiting groove structure and the first trigger switch and the second trigger switch are pressed, the high-pressure blowing device blows air onto the bearing surface of the flip plate, and the settling airflow device forms a downward airflow.

[0013] In another aspect, the present invention also provides a control method for an intelligent narcotic and psychotropic drug container disposal device, the control method comprising: Obtain user identity information; When the user's identity information is verified and the container to be destroyed is placed in the accommodating cavity, the information of the container to be destroyed is obtained, wherein the information of the container to be destroyed includes the type and weight of the container to be destroyed; Retrieve the weight of the empty container corresponding to the type of container to be destroyed; Calculate the difference between the weight of the container to be destroyed and the weight of the empty container; If the difference between the weight of the container to be destroyed and the weight of the empty container is less than a preset weight value, then the container to be destroyed is put into the pulverizing chamber. The container to be destroyed in the crushing chamber is crushed.

[0014] In some optional embodiments, the control method further includes: If the difference between the weight of the container to be destroyed and the weight of the empty container is greater than or equal to a preset weight value, an alarm will be issued.

[0015] In some optional embodiments, the control method further includes: Determine whether there are multiple containers to be destroyed on the container flipping device; If there are multiple containers to be destroyed on the container flipping device, an alarm will be issued.

[0016] As can be seen from the above, the intelligent narcotic and psychotropic drug container disposal device and its control method provided by the present invention have the following beneficial technical effects: This invention integrates an identification module, a container flipping device, a weighing module, a visual recognition module, and a crushing device onto a frame, creating an automated and simple destruction path. Specifically, a container flipping device positioned between the receiving chamber and the pulverizing chamber replaces the traditional horizontal pushing mechanism. This allows the container to be destroyed to fall vertically into the pulverizing chamber by gravity after the weighing module detects its weight and the visual recognition module confirms its type. This process not only simplifies the mechanical transmission chain and eliminates the risk of jamming caused by horizontally pushing soft containers, but also effectively blocks the upward diffusion of pulverized dust by physically isolating the upper and lower chambers in a horizontal state through the flipping plate. Based on this, combined with the collaborative work of the weighing module and the visual recognition module, the system can accurately obtain container type and weight data, and then determine whether the residual liquid volume is compliant based on the control logic. The flipping and pulverizing operations are only performed when the conditions are met. This effectively solves the core problems of low efficiency due to cumbersome processes, poor reliability due to complex mechanical structures, and maintenance difficulties caused by dust contamination sensors in existing technologies. It significantly improves the stability and consistency of equipment operation, ensures the automation and safety of medical waste treatment, and reduces long-term operation and maintenance costs.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0020] Based on the problems pointed out in the background art regarding existing pharmaceutical container destruction equipment, such as cumbersome destruction processes, complex mechanical structures prone to jamming, and sensors susceptible to dust contamination, this invention provides an intelligent narcotic and psychotropic drug container disposal device and its control method. The aim is to simplify the feeding process of the pharmaceutical container destruction equipment, eliminate the risk of mechanical jamming, prevent dust contamination of detection elements, and improve the reliability and ease of maintenance of the equipment.

[0021] See Figures 1 to 4 The intelligent narcotic and psychotropic drug container disposal equipment of the present invention includes: a frame 1 having a feeding port 11, and a accommodating cavity 12 and a crushing cavity 13 arranged vertically, the feeding port 11 being connected to the accommodating cavity 12; an identity recognition module 2, disposed on the frame 1, for recognizing the user's identity information; a container flipping device 3, disposed between the accommodating cavity 12 and the crushing cavity 13, for feeding the container to be destroyed into the crushing cavity 13 by flipping; a weighing module 4, disposed on the container flipping device 3, for detecting the weight of the container to be destroyed; a visual recognition module, disposed in the accommodating cavity 12 or on the container flipping device 3, for recognizing the type of the container to be destroyed; and a crushing device 5, disposed in the crushing cavity 13, for crushing the container to be destroyed in the crushing cavity 13.

[0022] In the above, the frame 1 is used to support and fix the main structure of the various functional components of the equipment. The material of the frame 1 can be set according to the actual situation, such as high-strength stainless steel, aluminum alloy or engineering plastic, etc. The present invention does not make special limitations on this. The feeding port 11 is formed on the top, upper side or middle of the frame 1 and is directly connected to the lower receiving cavity 12, forming the only channel for the container to be destroyed to enter the equipment. This single feeding port 11 allows the user to directly put different specifications and types of medicine containers into the equipment without pre-classifying the containers, which simplifies the operation process. The shape and size of the feeding port 11 can be set according to the maximum external size of common medicine containers. For example, it can be set as an inverted conical wide-mouth structure to guide the container to fall smoothly into the receiving cavity 12.

[0023] The identity recognition module 2 is a functional unit used to verify the operator's authorization. It is located on the outer surface of the frame 1 or near the feeding port 11 to facilitate user identity verification before feeding. The identity recognition module 2 can be a fingerprint reader, a facial recognition camera, an IC card reader, or a password input keyboard, or a combination of these methods. In the solution of this invention, the identity recognition module 2 is electrically connected to the equipment's control system 100. Only after recognizing legitimate user identity information will the equipment initiate subsequent receiving and processing procedures, thereby ensuring the security and traceability of the drug container destruction process, realizing the logical control of authentication before feeding, and preventing unauthorized operation.

[0024] The container tilting device 3 can switch between a horizontal and a vertical state: in the horizontal state, the container tilting device 3 acts as a bottom sealing member of the receiving cavity 12, receiving the container to be destroyed falling from the feeding port 11; in the vertical state, it releases the sealing, allowing the container to be destroyed to fall directly into the crushing cavity 13 below under the action of gravity. This method of vertical falling by gravity replaces the existing horizontal pushing mechanism, effectively avoiding the problem of material jamming caused by container rolling or irregular shape. The specific structural form of the container tilting device 3 can be various, such as a tilting plate structure that rotates around an axis, a tilting tray structure, or a turntable structure, as long as the switching between the bearing and releasing functions can be realized. Those skilled in the art can flexibly set it.

[0025] The weighing module 4 can be a strain gauge load cell, a piezoelectric sensor, or other high-precision electronic weighing element. In the present invention, the weighing module 4 is used not only to obtain the total weight, but also to calculate the amount of residual liquid in the container to be destroyed in conjunction with the visual recognition results. By integrating the weighing module 4 onto the container flipping device 3, the weighing can be completed directly when the container to be destroyed is stationary at the receiving position, without the need for additional transfer steps, thus improving detection efficiency. The detection range and accuracy of the weighing module 4 can be set according to the actual weight range of the processed drug containers, for example, a range of 0-500g with an accuracy of 0.1g, or it can be adjusted according to actual needs. The embodiments of the present invention do not impose any special limitations on this.

[0026] The visual recognition module can be installed on the inner wall of the accommodating cavity 12 for top-down shooting, or integrated above or to the side of the container flipping device 3 for side-down shooting. The visual recognition module is used to identify the type (such as ampoules, vials, infusion pumps, etc.), quantity, and surface markings (such as QR codes, barcodes) of the containers to be destroyed. The visual recognition module includes a camera element 101, a barcode scanning element 102, and a supplementary lighting element 103 to ensure that clear images can be obtained under different lighting conditions. The visual recognition module can complement the weighing module 4: the visual recognition module extracts information through camera and barcode scanning, and then transmits the extracted information to the control system 100. The control system 100 determines the standard tare weight of the corresponding type of container. The containers to be destroyed may contain residual liquid and / or foreign matter. The weighing module 4 can detect the actual total weight of the containers to be destroyed. The two can be combined to calculate the difference weight, thereby determining whether it meets the destruction standard.

[0027] The crushing device 5 is fixedly installed in the crushing chamber 13 located in the lower layer. The crushing device 5 can be a blade shaft crusher, hammer crusher, or shear crusher, etc. Its power source can be a rotating blade assembly driven by a motor. When the container tilting device 3 is activated to put the container into the crushing chamber 13, the crushing device 5 starts to physically destroy the container to be destroyed. The crushing device 5 is isolated from the upper accommodating chamber 12 by the container tilting device 3. This layout helps to block the upward diffusion path of dust during the crushing operation and protect the visual recognition module above from contamination. The power, speed and blade material of the crushing device 5 can be selected according to the hardness of the container to be processed and the processing volume requirements. For example, the blade can be made of hard alloy material to improve wear resistance. This embodiment of the invention does not make any special limitations in this regard.

[0028] This invention constructs a single-channel destruction system integrating identity verification, intelligent identification, precise weighing, and gravity feeding. Specifically, it compactly integrates the identity recognition module 2, weighing module 4, visual recognition module, and container tilting device 3 in space, and uses the container tilting device 3 as a dynamic isolation valve between the accommodating chamber 12 and the crushing chamber 13 to achieve fully automated closed-loop control from feeding to crushing. This architecture eliminates the complex push rod mechanism and dual feeding port 11 design in traditional equipment, and uses vertical gravity flow instead of horizontal mechanical thrust, significantly simplifying the mechanical transmission chain and improving the overall reliability of the system.

[0029] The working process and principle of the intelligent narcotic and psychotropic drug container disposal equipment of the present invention are as follows: The user first completes identity verification through the identity recognition module 2, and the equipment unlocks to allow feeding. The user places the container to be destroyed into the receiving cavity 12 through a single feeding port 11, and the container falls onto the horizontally positioned container flipping device 3. At this time, the weighing module 4, located on the container flipping device 3, immediately collects the container weight data, while the visual recognition module takes a picture of the container to determine its type and quantity. The control system 100 retrieves the weight of the corresponding standard empty container based on the identified container type and calculates the weight difference based on the data from the weighing module 4. If all indicators meet the preset destruction conditions, the container flipping device 3 is driven to flip to a vertical position. Under the action of gravity, the container detaches from the container flipping device 3 and falls freely into the crushing chamber 13 below. Subsequently, the container flipping device 3 resets, and the crushing device 5 starts to crush the container that has fallen into the crushing chamber 13. Throughout the process, the container flipping device 3 remains horizontally closed during non-working periods, effectively preventing dust in the crushing chamber 13 from drifting upwards to the receiving cavity 12, thereby protecting the visual recognition module from contamination.

[0030] Preferably, the container tilting device 3 includes a tilting motor 31 and a tilting plate 32. The tilting plate 32 is used to support the container to be destroyed. The weighing module 4 is disposed on the tilting plate 32 and is used to detect the weight of the container to be destroyed on the tilting plate 32. The tilting motor 31 is disposed between the accommodating cavity 12 and the crushing cavity 13. The output end of the tilting motor 31 is connected to the tilting plate 32 and can drive the tilting plate 32 to switch between a horizontal state and a vertical state. When the tilting plate 32 is in a horizontal state, the tilting plate 32 isolates the accommodating cavity 12 and the crushing cavity 13. When the tilting plate 32 switches from a horizontal state to a vertical state, the container to be destroyed on the tilting plate 32 falls from the tilting plate 32 into the crushing cavity 13 by its own weight. The tilting motor 31 can be a servo motor, a stepper motor, or a geared motor with a self-locking function, etc. The embodiments of the present invention do not make any special limitations on this.

[0031] The tilting motor 31 is fixedly installed inside the frame 1, specifically on the partition structure between the receiving chamber 12 and the crushing chamber 13. Its output shaft is connected to the rotating shaft of the tilting plate 32 via a coupling or direct connection. In this invention, the tilting motor 31 serves as a drive source, its function being to precisely control the posture of the tilting plate 32 in response to control commands. Through its mechanical connection with the tilting plate 32, it achieves the transition from a horizontal receiving posture to a vertical unloading posture, thereby completing the process of placing the container to be destroyed.

[0032] The flip plate 32 serves as a support component for receiving and temporarily storing containers such as medicine bottles, ampoules, or infusion pumps to be destroyed. Its shape can be set according to actual conditions, such as a rectangular plate, a disc, or a shallow disc structure with edge baffles. The material can be corrosion-resistant and easy-to-clean stainless steel or engineering plastic. When the flip plate 32 is set horizontally, its upper surface forms the bottom boundary of the receiving cavity 12 and closes the top entrance of the crushing cavity 13. When the flip motor 31 drives it to rotate to a vertical state, the surface tilt angle of the flip plate 32 changes, causing the object placed on it to lose its support balance. In this invention, the flip plate 32 not only bears the load but also acts as an isolation barrier. Through cooperation with the flip motor 31, it physically blocks the connection between the upper and lower cavities in a horizontal state, preventing dust in the crushing cavity 13 from rising and contaminating the visual recognition module above. During the action switching, it uses gravity to guide the container to slide down, avoiding the jamming problem that may occur with traditional push rod mechanisms.

[0033] More preferably, the weighing module 4 is directly integrated onto the tilting plate 32, for example, it can be embedded in the bottom center of the tilting plate 32, or installed on the cantilever structure supporting the tilting plate 32, so that the weight change of the tilting plate 32 directly affects the sensing end of the weighing module 4. In the solution of the present invention, the weighing module 4 and the tilting plate 32 form an integrated structure for weighing and bearing, and the weight data can be obtained after the container falls into the tilting plate 32 without the need for an additional pushing or transferring mechanism. The weight data is then transmitted to the control system 100. Its close cooperation with the tilting plate 32 ensures the stability and accuracy of the weighing process. Specifically, in the initial state, the tilting motor 31 drives the tilting plate 32 to keep it horizontal and stationary. At this time, the tilting plate 32 is like a valve base plate, completely isolating the upper receiving cavity 12 from the lower crushing cavity 13 to prevent dust diffusion. When a user places a container into the disposal area, the container falls onto the tilting plate 32. The weighing module 4 integrated on the plate collects the weight signal, while the visual recognition module confirms the container type. Once the control system 100 determines that the disposal conditions are met, it sends a rotation command to the tilting motor 31. The tilting motor 31 drives the tilting plate 32 to rotate about 90° around its axis to a vertical position. During this process, the bearing surface of the tilting plate 32 changes from horizontal to vertical. The container to be disposed of naturally detaches from the surface of the tilting plate 32 under the action of gravity and falls vertically into the crushing chamber 13 below, entering the crushing device 5 for processing. After the disposal is completed, the tilting motor 31 drives the tilting plate 32 in the opposite direction to return to a horizontal position, re-closes the crushing chamber 13, and prepares to receive the next container.

[0034] Preferably, a high-pressure air blowing device 6 is provided between the receiving cavity 12 and the pulverizing cavity 13 or on the tilting plate 32. The high-pressure air blowing device 6 is configured to blow air onto the bearing surface of the tilting plate 32. The high-pressure air blowing device 6 can be located in the gap between the receiving cavity 12 and the pulverizing cavity 13, or it can be directly integrated into the edge or bottom of the tilting plate 32 as a fluid output component. The high-pressure air blowing device 6 uses high-speed airflow to physically sweep the bearing surface of the tilting plate 32 to remove debris, liquid droplets, or dust particles that may remain on the surface of the tilting plate 32 after the container to be destroyed falls into the pulverizing cavity 13. The high-pressure air blowing device 6 and the container tilting device... The flipping plate 32 in position 3 forms a linkage relationship: when the flipping motor 31 drives the flipping plate 32 to complete the process of resetting from the vertical state to the horizontal state, or when the flipping plate 32 is in the horizontal state and it is confirmed that the container has fallen, the high-pressure blowing device 6 is activated and sprays high-pressure gas onto the bearing surface of the flipping plate 32. Through this linkage, the high-pressure blowing device 6 can blow the residue away from the bearing surface and make it fall into the crushing chamber 13 below without introducing mechanical contact parts, thereby maintaining the cleanliness of the surface of the flipping plate 32, ensuring that the containers to be destroyed placed later can be accurately weighed by the weighing module 4, and avoiding cross-contamination between different containers.

[0035] In one optional embodiment, the high-pressure blowing device 6 may include one or more nozzles and an air guide pipe connected to an external air source or a built-in micro air pump; the nozzle orientation can be adjusted to face the bearing surface of the flip plate 32. In another optional embodiment, the high-pressure blowing device 6 may also be composed of an array of multiple micropores arranged along the width direction of the flip plate 32, forming a uniform air curtain covering the entire bearing surface through an internal air pressure chamber. The air source can be compressed air or filtered clean gas; this embodiment of the invention does not impose any particular limitation on this. Furthermore, the triggering timing of the high-pressure blowing device 6 can be synchronized with the action signal of the flip motor 31, or it can be triggered by an independent sensor detecting the completion of the flip plate 32's reset. Its operating duration can be a short-term pulsed spray or a continuous spray lasting several seconds; the specific parameters can be adjusted according to the properties of the residue.

[0036] Specifically, after the container tilting device 3 completes the action of putting the container to be destroyed into the crushing chamber 13, the tilting plate 32 rotates from a vertical state to a horizontal state to close the passage between the receiving chamber 12 and the crushing chamber 13. During or after this reset process, the control system 100 issues a command to start the high-pressure blowing device 6. The high-pressure airflow is ejected from the nozzle of the high-pressure blowing device 6 and acts directly on the bearing surface of the tilting plate 32. The shearing force generated by the airflow peels off the tiny fragments of medicine bottles, glass shards of ampoules, or residual medicine attached to the tilting plate 32 and pushes these residues away from the tilting plate 32 along its surface. By setting the high-pressure blowing device 6, the tilting plate 32 can be automatically cleaned after each container destruction, solving the problem of residual debris or liquid on the surface of the tilting plate 32 causing weighing errors or contaminating the next container. This ensures the continuity of weighing accuracy and the hygiene standards of the system operation, and improves the long-term stability and reliability of the equipment.

[0037] More preferably, the bearing surface of the flip plate 32 is formed with multiple parallel micron-level grooves. The groove direction of all micron-level grooves is the same as the falling direction of the container to be destroyed when the flip plate 32 is flipped. The micron-level grooves can be microscale groove structures formed by mechanical processing, laser etching, or molding. The width, depth, and spacing of these micron-level grooves can be set according to actual cleaning needs and processing precision. For example, the width can be tens to hundreds of microns, and the depth can be several to tens of microns. This embodiment of the invention does not impose any special limitations on this. The micron-level grooves optimize the flow characteristics of the airflow blown by the high-pressure blowing device 6 on the surface of the flip plate 32. When the high-pressure blowing device 6 blows air onto the surface of the flip plate 32, the airflow enters the interior of the micron-level grooves and is guided and constrained by the sidewalls of the grooves, forming a high-speed directional airflow along the extension direction of the grooves. This directional airflow can significantly enhance the shearing force and peeling effect on dust, liquid residue, or tiny debris attached to the surface of the flip plate 32, thereby improving cleaning efficiency.

[0038] The grooves at the micron level are oriented in the same direction as the container to be destroyed, meaning the extension trajectory of the grooves is consistent with the trajectory of the container sliding down the tilting plate 32 under gravity. This consistent directional design has multiple advantages: Firstly, during the sliding process, the bottom of the container contacts the groove in parallel, avoiding any obstruction or jamming that might occur with the transverse grooves, while also reducing friction between the container and the groove, ensuring that the container can fall smoothly and unimpeded into the crushing chamber 13 below. Secondly, when the high-pressure blowing device 6 is working, the airflow flowing along the groove direction not only carries away surface contaminants but also blows the scattered liquid or fine particles away from the surface of the tilting plate 32 along the falling direction, preventing contaminants from accumulating on the surface of the tilting plate 32 or diffusing back into the containment chamber 12.

[0039] Specifically, after the container tilting device 3 completes the feeding action and puts the container to be destroyed into the crushing chamber 13, the tilting plate 32 returns to a horizontal state. At this time, the high-pressure blowing device 6 is activated, spraying high-pressure airflow onto the bearing surface of the tilting plate 32. When the airflow comes into contact with the surface with micron-level grooves, it is divided and guided into each parallel groove channel. Since the groove direction is consistent with the preset main airflow direction and the container falling direction, the airflow forms a laminar or turbulent acceleration effect in the groove, sweeping across the entire bearing surface at a high speed along the length of the groove. During this process, the shear force generated by the airflow forcibly peels off the powder, glass fragments or droplets adhering to the surface and pushes them to move along the falling direction guided by the groove, eventually detaching from the tilting plate 32 and entering the processing space below or being captured by a special collection structure. The whole process utilizes the guiding effect of the microstructure on the macro airflow to achieve a highly efficient and directional self-cleaning function.

[0040] More preferably, a hydrophobic layer is provided on the surface of the micron-level trench. The hydrophobic layer can be a functional film layer with low surface energy properties coated or formed on the surface of the micron-level trench. This hydrophobic layer can reduce the adhesion of liquid on the bearing surface of the flip plate 32, prevent residual liquid in the container to be destroyed from dripping and remaining in the trench, thereby avoiding residual droplets from affecting the detection accuracy of the subsequent weighing module 4 or causing bacterial growth. The hydrophobic layer and the micron-level trench work together to generate a superhydrophobic effect by combining the micro-nano structure with the low surface energy material, making it difficult for droplets on the contact surface to wet the surface and roll off quickly. The material of the hydrophobic layer can be set according to the actual situation, such as polytetrafluoroethylene (PTFE) coating, silicone resin coating, fluorocarbon coating or nano-silica composite hydrophobic material, etc. The embodiments of the present invention do not make special limitations in this regard. In practice, the hydrophobic layer can be formed on the inner wall and bottom of the micron-level trench through processes such as spraying, dip coating, chemical vapor deposition or plasma treatment. When the high-pressure air blowing device 6 blows air to clean the flip plate 32, due to the presence of the hydrophobic layer, the residual trace liquid is more easily peeled off and carried away by the airflow, thereby achieving a nearly completely dry surface state, significantly improving the self-cleaning ability of the equipment, extending the service life of the equipment and reducing the risk of corrosion and pollution.

[0041] Specifically, in the technical solution of this invention, when the container to be destroyed is placed on the flip plate 32 with micron-level grooves and a hydrophobic layer on its surface, if the container leaks or residual liquid flows out, the liquid will spherically aggregate due to the low surface energy characteristics of the hydrophobic layer, preventing it from penetrating or adhering to the depths of the grooves. At this time, in conjunction with the airflow generated by the high-pressure blowing device 6 in the aforementioned embodiment, the droplets will be quickly blown away from the surface of the flip plate 32 along the groove opening direction, ensuring the cleanliness of the bearing surface of the flip plate 32 and providing an accurate basic environment for the next weighing and identification operation. Through the above method, the hydrophobic layer further reduces the interaction force between the liquid surface tension and the solid surface, solving the problem that liquid is easy to remain inside the microstructure and difficult to remove, thereby improving weighing accuracy, enhancing the self-cleaning effect of the equipment, and preventing bacterial growth and component corrosion.

[0042] In a preferred embodiment, see Figures 3 to 5The output end of the flipping motor 31 is connected to a gear 33. A sliding groove structure 14 is provided between the frame 1, the accommodating cavity 12, and the crushing cavity 13. A sealing plate 35 is slidably disposed on the sliding groove structure 14. The sealing plate 35 is connected to or forms a rack 34 that meshes with the gear 33. When the flipping plate 32 switches from a horizontal state to a vertical state, the gear 33 drives the rack 34 to move, thereby causing the sealing plate 35 to slide out of the sliding groove structure 14 to isolate and seal the accommodating cavity 12 and the crushing cavity 13. The output end of the flipping motor 31 is connected to... The gear 33 serves as the driving wheel on the motor shaft. As the hub for power transmission and conversion, the gear 33 converts the rotational motion of the flip motor 31 into linear motion. When the flip motor 31 starts and drives the flip plate 32 to move, the gear 33 rotates synchronously. Then, through meshing with the rack 34, it drives the sealing plate 35 to produce displacement. The specific parameters of the gear 33, such as the module and the number of teeth, can be set according to the actual situation. For example, it can be a standard spur gear 33 or a helical gear 33. This embodiment of the invention does not make any special limitations on this.

[0043] The chute structure 14 can be a guide channel set on the frame 1 at the junction of the receiving cavity 12 and the crushing cavity 13. It provides a trajectory constraint for the linear motion of the sealing plate 35, preventing the sealing plate 35 from deflecting or getting stuck during movement. The cooperation relationship between the chute structure 14 and the sealing plate 35 can be that the side or back of the sealing plate 35 is embedded in the chute structure 14 and slides along the extension direction of the chute. The shape of the chute structure 14 can be set according to the cross-sectional shape of the sealing plate 35. For example, it can be a rectangular groove, a T-shaped groove or a dovetail groove. The embodiments of the present invention do not make any special limitations on this. The sealing plate 35 is used to block the communication between the receiving cavity 12 and the crushing cavity 13. When the tilting plate 32 opens to discharge material, it fills the gap caused by the rotation of the tilting plate 32, thereby forming a dynamic sealing barrier. The connection between the sealing plate 35 and the rack 34 can be a fixed connection, integral molding, or connection through fasteners, as long as it can ensure that the rack 34 moves synchronously with the sealing plate 35. The material of the sealing plate 35 can be selected according to the requirements of wear resistance and sealing performance. For example, it can be a stainless steel plate, an engineering plastic plate, or a metal plate with a wear-resistant coating on the surface. This embodiment of the invention does not make any special limitations on this. The rack 34 converts the rotational torque of the gear 33 into a linear thrust that moves the sealing plate 35. When the gear 33 rotates, its teeth sequentially engage the teeth of the rack 34, forcing the rack 34 to move linearly along the axial direction, thereby driving the sealing plate 35 connected to it to slide out of the slide groove structure 14. The length of the rack 34 can be set according to the required stroke of the sealing plate 35, for example, it can be a dimension slightly longer than the width of the sealing plate 35, to ensure that the sealing plate 35 can fully extend to cover the gap. This embodiment of the present invention does not impose any special limitation on this.

[0044] In actual operation, when the container to be destroyed needs to be crushed, the control system 100 issues a command to start the flipping motor 31. The output end of the flipping motor 31 begins to rotate, directly driving the flipping plate 32 to flip from a horizontal state to a vertical state, so that the container to be destroyed falls into the crushing chamber 13 under the action of gravity. On the other hand, the gear 33 fixed to the output end of the flipping motor 31 rotates accordingly. The rotating gear 33 drives the rack 34 meshing with it to move linearly. Since the rack 34 is connected to the sealing plate 35, the movement of the rack 34 directly pulls the sealing plate 35 to slide outward along the preset sliding groove structure 14. During the process of the flipping plate 32 being completely flipped to a vertical state, the sealing plate 35 just moves to a position that can close the connection between the accommodating chamber 12 and the crushing chamber 13, thereby cutting off the direct connection between the upper and lower chambers in physical space and preventing the dust generated in the crushing chamber 13 due to the crushing operation from flying upward into the accommodating chamber 12. In this way, the material feeding and sealing actions can be driven simultaneously by a single power source, the flipping motor 31. Through the mechanical linkage of the gear 33 and the rack 34, the extension timing of the sealing plate 35 is strictly synchronized with the flipping action of the flipping plate 32. There is no need to set up an additional independent sealing drive cylinder or motor, which simplifies the equipment structure and reduces the control complexity. At the same time, since the sealing plate 35 automatically slides out when the flipping action is triggered, it can block the passage between the receiving cavity 12 and the crushing cavity 13 in time, effectively preventing the fine dust generated during the crushing process from floating up and contaminating the visual recognition module in the receiving cavity 12, thus improving the long-term operational stability and measurement accuracy of the equipment.

[0045] Preferably, a settling airflow device 7 is provided inside the crushing chamber 13. The settling airflow device 7 is configured to generate a downward airflow to prevent dust generated by the crushing device 5 when crushing the container to be destroyed from floating upwards. The settling airflow device 7 can be an airflow generating component installed inside the crushing chamber 13 to generate directional airflow to control the movement trajectory of dust. The settling airflow device 7 utilizes the principle of aerodynamics to construct a stable downward flow field, i.e., an air curtain, in the crushing operation area. It can also have a close cooperation relationship with the crushing device 5 and the sealing plate 35. When the crushing device 5 crushes the medicine container at high speed, fine dust particles will inevitably be generated. At this time, the settling airflow device 7 is activated, and the generated downward airflow covers the top and surrounding of the crushing area, forming an air curtain. This forces the dust particles that fly upwards due to the crushing action to change their movement direction and instead settle downwards with the airflow. Through this cooperation, the settling airflow device 7 effectively blocks the path of dust to travel upwards to the receiving chamber 12, thereby avoiding dust contamination of the visual recognition module or other sensors located above, and ensuring the detection accuracy and operational stability of the equipment in continuous working condition. In practical applications, the settling airflow device 7 may include a small centrifugal fan and a porous flow equalization plate installed on the inner wall of the top of the crushing chamber 13. When the control system 100 of the equipment detects the start signal of the crushing device 5, the control module immediately sends a command to the settling airflow device 7. The fan rotates at a preset speed, and the airflow is rectified by the flow equalization plate and blown evenly to the crushing device 5 area. If a dust concentration sensor is installed in the crushing chamber 13, the system can also dynamically adjust the fan speed according to the real-time monitored dust concentration data, thereby adjusting the speed of the settling airflow to achieve the best balance between energy consumption and dust removal effect. For example, when a high dust concentration is detected, the airflow speed is automatically increased to enhance the pressing effect; conversely, the airflow speed is reduced to reduce noise and energy consumption. Through the above method, the dust generated during the container crushing process can be effectively suppressed and prevented from spreading to the containment chamber 12 and contaminating the visual recognition module, thereby ensuring the long-term reliability of the equipment operation and the accuracy of the measurement data, reducing the maintenance frequency caused by dust accumulation, and meeting the cleanliness requirements of the medical waste treatment environment.

[0046] Preferably, a limiting groove structure 15 is provided on the frame 1 between the receiving cavity 12 and the crushing cavity 13. The limiting groove structure 15 is used to limit the protruding end of the sealing plate 35. A first trigger switch 8 and a second trigger switch 9 are provided in the limiting groove structure 15. The first trigger switch 8 can trigger the high-pressure blowing device 6, and the second trigger switch 9 can trigger the settling airflow device 7. When the protruding end of the sealing plate 35 extends into the limiting groove structure 15 and the first trigger switch 8 and the second trigger switch 9 are pressed, the high-pressure blowing device 6 blows air onto the bearing surface of the flipping plate 32, and the settling airflow device 7 forms a downward airflow. The limiting groove structure 15 provides precise path constraint for the movement of the sealing plate 35 and controls the movement of the sealing plate 35 to a specific location. When the position is fixed, a physical stop or trigger interface is provided. The limiting groove structure 15 and the sealing plate 35 form a sliding fit relationship. When the sealing plate 35 slides out of the sliding groove structure 14 under the drive of the gear 33 and the rack 34 to isolate the accommodating cavity 12 and the crushing cavity 13, the protruding end of the sealing plate 35 simultaneously enters the interior of the limiting groove structure 15. The specific shape of the limiting groove structure 15 can be set according to the actual situation. For example, it can be a rectangular groove, a U-shaped groove or a dovetail groove. The embodiments of the present invention do not make special limitations on this, as long as it can accommodate the protruding end of the sealing plate 35 and guide it to the preset trigger position. Through the above cooperation, the limiting groove structure 15 ensures that the sealing plate 35 can be stably maintained in the specified position after the isolation action is completed. The first trigger switch 8 can be a mechanical or electronic signal generating element installed on the inner wall or bottom of the limiting groove structure 15. The first trigger switch 8 is electrically connected or signal communication connected to the high-pressure blowing device 6. When the extended end of the sealing plate 35 contacts and presses the first trigger switch 8 during movement, the first trigger switch 8 generates a closing signal or a level change. This signal is transmitted to the control system 100 or directly connects the power circuit of the high-pressure blowing device 6, thereby triggering the high-pressure blowing device 6 to work. The specific type of the first trigger switch 8 can be set according to the actual situation. For example, it can be a micro switch, limit switch, pressure sensor or Hall switch. This embodiment of the invention does not make any special limitation on this. Through the cooperation of the first trigger switch 8 and the sealing plate 35, the logic of blowing and cleaning is realized only after the sealing plate 35 is in place, avoiding energy waste or dust dispersion caused by ineffective blowing. The second trigger switch 9 can refer to another signal generating element installed in the limiting groove structure 15, which is parallel or staggered with the first trigger switch 8. The second trigger switch 9 is electrically connected or signal communication connected to the settling airflow device 7. When the extended end of the sealing plate 35 continues to move or presses the second trigger switch 9 at the same time, the second trigger switch 9 generates a trigger signal, thereby activating the settling airflow device 7 to form a downward airflow.The second trigger switch 9 can be set in the same or different position as the first trigger switch 8. For example, they can be set in series so that the same pressing action is triggered at the same time, or they can be set in stages so that they are triggered separately at different stroke depths. This embodiment of the invention does not make any special limitation on this. Through the second trigger switch 9, it is ensured that the settling airflow device 7 only intervenes to work in a specific stage when the crushing chamber 13 is effectively sealed and is preparing to crush or is crushing, thereby enhancing the system's targeted dust control.

[0047] Specifically, when the container tilting device 3 feeds the container to be destroyed, the tilting motor 31 drives the gear 33 to rotate. The gear 33 drives the rack 34, which meshes with it, to move. The rack 34 then pushes the sealing plate 35 to slide along the sliding groove structure 14. As the extended end of the sealing plate 35 gradually penetrates into the limiting groove structure 15, the front end of the sealing plate 35 first contacts and physically presses the first trigger switch 8 and the second trigger switch 9, or presses the first trigger switch 8 and the second trigger switch 9 in a preset order. Once the first trigger switch 8 is pressed, the high-pressure blowing device 6 immediately responds and sprays high-pressure gas onto the bearing surface of the tilting plate 32 to remove residual liquid or debris, which then enters the crushing chamber 13. At the same time or subsequently, when the second trigger switch 9 is pressed, the settling airflow device 7 is activated, forming a stable downward airflow field in the crushing chamber 13. This series of actions is entirely controlled by the sealing plate. The mechanical displacement trigger of plate 35 eliminates the need for additional photoelectric sensor detection or complex software timing judgment. The deterministic nature of mechanical linkage ensures the action logic of sealing first, followed by air blowing / settling. In practical applications, since the sealing plate 35 seals and isolates the accommodating cavity 12 and the crushing cavity 13, the flipping plate 32 can remain vertical while the crushing device 5 crushes the container. Of course, the second trigger switch 9 can also keep the settling airflow device 7 blowing downward for a preset time. Within the preset time, the flipping plate 32 resets to a horizontal state. Since the settling airflow device 7 continuously forms a downward airflow, the dust will not float. Thus, after the flipping plate 32 resets, it can still continue to isolate the accommodating cavity 12 and the crushing cavity 13. That is, the sequential actions of sealing plate 35 isolation, airflow isolation, and flipping plate 32 isolation ensure continuous dust isolation and prevent dust from entering the accommodating cavity 12. For the high-pressure blowing device 6, a third trigger switch can also be set. The first trigger switch 8 and the third trigger switch are connected in parallel in the circuit and can both control the start of the high-pressure blowing device 6. The third trigger switch can be set at the extended end of the flip plate 32. When the flip plate 32 is reset, the third trigger switch is pressed, so that the flip plate 32 can still be started to blow air onto the bearing surface of the flip plate 32 after it is reset. This allows the flip plate 32 to be cleaned in both horizontal and vertical states.

[0048] In some preferred embodiments, a labyrinth-type sealing structure is formed on the flip plate 32. When the flip plate 32 is in a horizontal state, the labyrinth-type sealing structure seals the gap between the flip plate 32 and the crushing chamber 13. The labyrinth-type sealing structure can be a non-contact or micro-contact tortuous path sealing structure provided on the edge of the flip plate 32 or a specific mating surface. This labyrinth-type sealing structure utilizes the principle of fluid dynamics to effectively block the tiny gap between the flip plate 32 and the crushing chamber 13 without relying on the frequent friction of the elastic seal. In a specific implementation, the labyrinth-style sealing structure can form a convex-concave interlocking or stepped fit with the inner wall of the crushing chamber 13, the sliding groove structure 14, or other fixed components. When the flip plate 32 is in a horizontal state to carry the container to be destroyed, the structure can seal the gap between the accommodating chamber 12 and the crushing chamber 13, preventing dust generated in the crushing chamber 13 from escaping upwards to the accommodating chamber 12. Compared with the barrier provided by the flip plate 32 alone, the sealing effect is significantly improved, thereby protecting the visual recognition module located above from contamination. Those skilled in the art can flexibly set the specific form of the labyrinth-type sealing structure in practical applications. For example, it can be a multi-stage throttling structure formed by alternating cooperation of multiple annular protrusions extending circumferentially along the flip plate 32 and corresponding annular grooves; it can also be a zigzag flow channel structure composed of a series of intersecting baffles; or a labyrinth channel formed by the cooperation of a deep groove opened on the side wall of the flip plate 32 and the protrusions on the inner wall of the crushing chamber 13. The embodiments of the present invention do not make special limitations on this. Regardless of the specific form adopted, the labyrinth-type sealing structure must ensure that when the flip plate 32 is closed, it maintains a very small assembly gap with the corresponding mating surface, so that dust particles cannot pass through the tortuous path by their own kinetic energy or weak airflow pressure difference.

[0049] Specifically, when the tilting plate 32 is driven by the tilting motor 31 to return from a vertical to a horizontal position, the labyrinth seal structure enters its working position. At this time, if there is positive pressure or dust rising tendency in the crushing chamber 13, the dust-laden airflow must undergo multiple turning, expansion, and diameter reduction processes set by the labyrinth seal structure when attempting to pass through the edge gap of the tilting plate 32. During this process, the airflow velocity is significantly reduced, and dust particles collide with the labyrinth wall due to inertia and settle, unable to continue rising with the airflow. This sealing method avoids the problem of traditional rubber sealing rings being prone to wear and aging under long-term high-frequency tilting action, leading to sealing failure. It is particularly suitable for the fine powder environment that may be generated during the disposal of pharmaceutical containers, ensuring the airtight isolation of each functional area inside the equipment.

[0050] In a preferred embodiment, three parallel annular ribs are machined at the lower surface edge of the flip plate 32, and three annular grooves with precisely corresponding positions are provided on the inner sidewall of the opening at the top of the crushing chamber 13. When the flip plate 32 is rotated to the horizontal closed position, the ribs are embedded in the grooves, but a micro-gap of 0.1mm-0.5mm is maintained between them, forming a typical labyrinth seal effect. When the crushing device 5 crushes the container, the generated dust airflow rises to the bottom of the flip plate 32 and is blocked by the labyrinth seal structure. Most of the dust falls back to the bottom of the crushing chamber 13 under the action of gravity or the settling airflow device 7. Only a very small amount of dust may enter the depth of the labyrinth channel, but cannot penetrate to the receiving cavity 12. In addition, the surface of the labyrinth seal structure can also be combined with the hydrophobic layer or micron-level groove design in the aforementioned embodiment to further reduce drug residue adhesion and facilitate the subsequent cleaning operation of the high-pressure blowing device 6. By using the above method, the physical resistance and time cost of dust penetration are increased by using the tortuous flow channel. Therefore, when the flip plate 32 is in a horizontal closed state, it can effectively block the diffusion of dust in the crushing chamber 13 to the receiving chamber 12, improve the reliability of equipment operation, reduce the frequency of maintenance, and ensure the accuracy of weighing and identification data.

[0051] A heat-generating device is installed inside the crushing chamber 13 or on the crushing device 5. The heat-generating device is configured to generate heat on the container to be destroyed during the crushing process. The heat-generating device can be an electric heating element or an infrared element installed on the inner wall, bottom or side wall of the crushing chamber 13, or it can be a heat-generating component integrated inside the cutter shaft, blade or rotor of the crushing device 5. The heat-generating device provides a thermal environment for the crushing process or the crushed material. The heat-generating device works in conjunction with the crushing device 5. When the crushing device 5 mechanically crushes the container to be destroyed, the heat-generating device is started synchronously or sequentially to heat the container fragments and any residual drug substances in the crushing chamber 13. Furthermore, through frictional heat cooperation with the crushing device 5 during the crushing of the container, it can accelerate the decomposition or evaporation of volatile drug components remaining on the container fragments, or cause certain heat-sensitive drug components to denature and become inactive, thereby achieving a deeper level of harmless treatment.

[0052] Specifically, the heat-generating device can be an annular heat-generating ring surrounding the inner wall of the crushing chamber 13, which directly heats the material inside the chamber through thermal radiation; it can also be an electric heating rod embedded inside the rotating blade of the crushing device 5, which directly transfers heat to the material in contact with the blade through thermal conduction; or it can be a heat-generating plate set at the bottom of the crushing chamber 13, which heats the material falling to the bottom through contact. The heat generation temperature and control logic can be set according to the actual situation. For example, it can be constant temperature heat generation, or it can be frequency conversion adjustment based on the feedback of the temperature sensor inside the crushing chamber 13. This embodiment of the invention does not make any special limitations on this. As long as the heat source structure can effectively generate heat to the container to be destroyed and its residues to achieve the purpose of inactivation or drying, it is within the protection scope of this invention.

[0053] With the above settings, the crushing device 5 can destroy the container. The frictional heat generated between the blades of the crushing device 5 and the container, as well as the heat generated by the heat-generating device, can achieve high-temperature sterilization, thereby realizing centralized processing of high-temperature sterilization and crushing of the container in the crushing chamber 13.

[0054] Preferably, the frame 1 is equipped with a post-treatment device communicating with the crushing chamber 13. The post-treatment device is configured to treat the waste gas generated when the crushing device 5 crushes the containers to be destroyed. The post-treatment device can be located outside or inside the frame 1 and is a waste gas purification unit communicating with the crushing chamber 13 via a pipe or a direct opening. This post-treatment device receives and treats the waste gas containing drug particles, dust, or volatile organic compounds generated by the crushing device 5 during the mechanical crushing of the containers to be destroyed, to prevent direct discharge into the external environment causing pollution or harm to the health of operators. In a specific implementation, the post-treatment device can be sealed to the exhaust port of the crushing chamber 13 to form a closed gas flow path. When the crushing device 5 is working, the accompanying airflow carries the waste gas into the post-treatment device. After internal filtration, adsorption, or chemical neutralization, the clean gas is discharged.

[0055] The internal structure of the post-treatment device can be set according to actual treatment needs. For example, it can be a filter component containing a high-efficiency particulate air (HEPA) filter to intercept small solid particles and drug dust; it can also be an adsorption component filled with activated carbon or other adsorption materials to adsorb volatile organic compounds or odor molecules in the exhaust gas; or it can be a sterilization and disinfection component integrating ultraviolet lamps or catalytic mesh to inactivate bioactive substances that may exist in the exhaust gas. This embodiment of the invention does not impose any special limitations on this, as long as it can achieve the function of purifying the exhaust gas. The connection between the post-treatment device and the pulverizing chamber 13 can be a rigid pipe connection or a flexible hose connection to adapt to different layout requirements.

[0056] In a preferred embodiment, an exhaust port is provided on the side wall or top of the frame 1. This exhaust port communicates with the upper space of the pulverizing chamber 13. A post-treatment device is installed at the exhaust port. The post-treatment device contains a primary filter, an activated carbon adsorption layer, and a high-efficiency particulate air filter membrane. When the pulverizing device 5 rotates at high speed to crush ampoules or vials, the generated fine glass dust and residual drug mist rise with the airflow and are drawn into the post-treatment device. The airflow first passes through the primary filter to remove large particulate impurities, then through the activated carbon adsorption layer to remove volatile organic compounds, and finally through the high-efficiency particulate air filter membrane to intercept submicron dust. The qualified air is discharged from the outlet of the post-treatment device. If the container being processed contains volatile narcotic drugs, a catalytic oxidation unit can be added to further decompose toxic gases. Through the above method, the exhaust gas generated by the pulverizing device 5 during operation can be collected and purified in a timely manner, effectively avoiding the direct emission of toxic and harmful gases and drug dust, achieving environmental compliance, ensuring the health and safety of operators, and expanding the applicable scenarios of the equipment.

[0057] Preferably, a flexible buffer structure 11a is provided on the inner side of the feeding port 11. The flexible buffer structure 11a is configured to buffer the fall of the container to be destroyed. The flexible buffer structure 11a can be a material layer or component with elastic deformation capability, such as flexible bristles, disposed on the inner wall surface or inner periphery of the feeding port 11. The flexible buffer structure 11a is configured to absorb the kinetic energy generated when the container to be destroyed enters the receiving cavity 12 through the feeding port 11 through its own physical properties, thereby reducing the direct rigid collision between the container and the rigid inner wall of the frame 1. The flexible buffer structure 11a forms a cooperative relationship with the feeding port 11. Its coverage area can be set according to the actual situation. For example, it can fully cover the entire inner wall surface of the feeding port 11, or it can be only set in the key areas where the container is likely to make contact during the fall trajectory. This embodiment of the invention does not make special limitations on this. In terms of material selection, the flexible buffer structure 11a can be made of silicone, rubber, polyurethane foam, or flexible strips with bristles, as long as it can achieve the function of buffering and shock absorption. For example, when the container to be destroyed is a glass ampoule, a direct impact on the inner wall of the metal or hard plastic feeding port 11 can easily cause the bottle to break into sharp fragments or cause premature leakage of the medicine. However, by setting up a flexible buffer structure 11a, the flexible material elastically indents or bends at the moment of impact, prolonging the impact time and reducing the instantaneous impact force. This allows the container to fall smoothly into the lower receiving cavity 12 at a lower speed and be caught by the container flipping device 3. This combination not only protects the integrity of the container to be destroyed and avoids the risk of unexpected breakage, but also effectively reduces mechanical noise and vibration during equipment operation.

[0058] As shown in the figure, the control method of the intelligent narcotic and psychotropic drug container disposal device of the present invention includes: S1: Obtain the user's identity information; The acquisition of user identity information refers to the control system 100 receiving and parsing authentication data input by the user through the identity recognition module 2. This identity information originates from credentials provided by the user through methods such as card swiping, fingerprint registration, facial recognition, or password input. Its function is to verify whether the operator has the legal authority to perform the task of destroying drug containers. Specifically, the identity recognition module 2 is installed on the rack 1. When a user is detected approaching or an operation command is triggered, the acquisition program is started, and the acquired biometric features or card information are compared with the authorized list in the preset database. For example, when medical personnel approach the sensing area of ​​the device with their work badge, the radio frequency reader reads the encrypted code in the work badge and sends it to the control unit for verification. Through this identity verification mechanism, it is ensured that only authorized personnel can initiate the subsequent destruction process, effectively preventing unauthorized personnel from misoperating or maliciously destroying containers of controlled drugs, and ensuring the safety and traceability of drug waste disposal.

[0059] S2: When the user's identity information is verified and the container to be destroyed is placed in the accommodating cavity 12, obtain the information of the container to be destroyed, wherein the information of the container to be destroyed includes the type and weight of the container to be destroyed; The acquisition of the type and weight of the container to be destroyed can be achieved by the system automatically triggering a data acquisition subroutine after successful identity verification, synchronously collecting the physical attribute information of the container. The type of the container to be destroyed is obtained by the visual recognition module through image acquisition and analysis of the container. Specifically, this can include using the camera element 101 to photograph the appearance of the container, and combining it with the supplementary lighting element 103 to optimize the image quality. Then, the built-in AI algorithm is used to identify the shape, size, label text or QR code / barcode information of the container, or directly using the barcode scanning element 102 to scan the QR code or barcode information to determine whether it is an ampoule, vial, or infusion pump, etc. The weight of the container to be destroyed is directly detected by the weighing module 4, which is integrated on the flip plate 32 that carries the container. It is used to sense the mass of objects placed on its surface in real time. For example, when the container is identified as a 10ml vial, the system marks the type as vial-10ml, and the weighing sensor displays a reading of 25.4g. By acquiring visual and weighing data in tandem, the system can complete multi-dimensional information collection in one go within the accommodating cavity 12 without manual sorting or additional handling, providing a reliable data foundation for subsequent accurate calculation of weight differences.

[0060] S3: Retrieve the weight of the empty container corresponding to the type of container to be destroyed; The step of retrieving the empty container weight corresponding to the type of container to be destroyed can be achieved by the control module retrieving the matching theoretical empty weight value from a pre-set standard tare weight database based on the identified container type index. This empty container weight is a standard reference value obtained in advance by statistically analyzing the weighing data of a large number of clean containers of the same specifications and taking the average value. It is stored in the device's non-volatile memory and serves as a benchmark for calculating the amount of residual substance. In terms of setup, the database establishes a one-to-one mapping relationship between container type identifiers and standard tare weights. When a specific type signal is received, the system automatically retrieves the corresponding value. For example, if the container type is identified as a 5ml ampoule, the system immediately retrieves the standard empty weight of 3.2g for this type of ampoule from the database; if it is identified as a 100ml infusion pump, it retrieves 15.0g. Through this dynamic retrieval mechanism, the system can adapt to the differences in tare weight of different container specifications, avoiding calculation errors caused by using fixed tare weight values ​​and ensuring the accuracy of the assessment.

[0061] S4: Calculate the difference between the weight of the container to be destroyed and the weight of the empty container; The calculation of the difference between the weight of the container to be destroyed and the weight of the empty container involves the control unit performing arithmetic operations to subtract the weight of the standard empty container from the actual total weight obtained above, thus obtaining an estimated mass of residue. This difference reflects the amount of remaining liquid or solid residue in the container and serves as the core basis for determining whether the container meets the conditions for direct destruction. The calculation process is completed in real time by the embedded processor. When the actual weight is greater than the weight of the empty container, the difference is positive, indicating the presence of residue; if the two are equal or close, the difference approaches zero. For example, if a vial actually weighs 25.4g, while its standard empty weight is 20.0g, the calculated difference is 5.4g, indicating that there may be approximately 5.4g of liquid or impurities remaining in the vial. By accurately calculating this difference, the system can quantify the residual state of the container, providing quantitative decision parameters for subsequent safety assessments.

[0062] S5: If the difference between the weight of the container to be destroyed and the weight of the empty container is less than the preset weight value, then the container flipping device 3 is activated to put the container to be destroyed into the crushing chamber 13. The activation of the container tilting device 3 to place the container to be destroyed into the crushing chamber 13 can refer to the control system 100 sending an action command to the drive unit of the container tilting device 3 to execute the material dropping operation when the difference meets the safety threshold condition. The preset weight value is the upper limit of allowable residue set according to the drug safety management regulations, usually a very small value, such as 0.5g or 1.0g, used to determine whether the container is in a basically empty state. When the calculated difference is less than the preset value, the container is determined to meet the destruction standard. The control system 100 controls the tilting motor 31 to rotate, driving the tilting plate 32 to switch from the horizontal receiving state to the vertical unloading state. At this time, the container to be destroyed detaches from the tilting plate 32 under the action of gravity and falls vertically into the crushing chamber 13 below. For example, if the preset weight value is set to 1.0g, and the calculated difference is 0.4g, which is less than 1.0g, the system determines that it is qualified and then starts the motor to tilt the tilting plate 32 90 degrees, and the container slides into the crushing chamber 13. In conjunction with the aforementioned weight acquisition and calculation steps, this step enables automated feeding based on intelligent judgment of residual liquid volume. This not only prevents containers containing large amounts of residual drugs from being mistakenly destroyed, but also uses gravity to replace mechanical pushing, completely eliminating the risk of material jamming.

[0063] S6: Start the crushing device 5 to crush the container to be destroyed in the crushing chamber 13.

[0064] The process of activating the pulverizing device 5 to pulverize the containers to be destroyed in the pulverizing chamber 13 can be achieved by the control system 100 activating the drive motor of the pulverizing device 5 after confirming that the container has safely fallen into the pulverizing chamber 13. This drives the blade assembly or grinding components to rotate at high speed, physically crushing the container. This step requires that the container has been accurately delivered to its designated position via the tilting device, which thoroughly breaks the medicine container into tiny fragments, rendering it ineffective and facilitating subsequent harmless disposal. Specifically, after receiving feedback that the tilting device has completed its reset, the control system 100 delays briefly to ensure the container has completely fallen into the pulverizing area before outputting a high-level signal to activate the pulverizing motor. For example, when the tilting plate 32 resets to a horizontal position and triggers the limit switch, the system immediately activates the hammer mill in the pulverizing chamber 13, pulverizing the falling ampoules or vials into fragments with a particle size of less than 5mm. Through this final processing step, combined with the preceding identity verification, intelligent identification, and residual liquid discrimination processes, a fully closed-loop automated operation from access control to safe destruction is achieved, significantly improving the efficiency, safety, and compliance of medicine container processing.

[0065] In an optional embodiment, the method of the present invention further includes: If the difference between the weight of the container to be destroyed and the weight of the empty container is greater than or equal to a preset weight value, an alarm will be issued. The alarm can be triggered by the control system 100 after determining that the residue exceeds the standard. The alarm method can include the sound and light alarm on the drive device emitting a buzzing sound and flashing red light, or a text warning message of "Residue exceeds the standard, please check" popping up on the device's touch screen, or sending an abnormal signal to the management backend through the network interface.

[0066] In one optional embodiment, the method of the present invention further includes: Determine whether there are multiple containers to be destroyed on the container flipping device 3; If there are multiple containers to be destroyed on the container flipping device 3, an alarm will be issued. This step can be a process in which the control system 100 counts and analyzes the containers to be destroyed, which are carried on the container tilting device 3, based on image data collected by the visual recognition module or weight distribution characteristics detected by the weighing module 4. When the above judgment result is yes, that is, the number is greater than 1, the control system 100 immediately interrupts the normal material feeding and crushing process and triggers an audible and visual alarm or an interface prompt to notify the user to intervene.

[0067] In one optional embodiment, the method of the present invention further includes: Obtain the dust concentration inside the pulverizing chamber 13; Adjust the settling airflow velocity of the settling airflow device 7 according to the dust concentration in the pulverizing chamber 13; Among them, the dust concentration is positively correlated with the settling airflow velocity of the settling airflow device 7; By installing a dust concentration sensor inside the pulverizing chamber 13, the dust concentration sensor is configured to collect environmental data in real time during the pulverizing process and transmit analog or digital signals to the control system 100. Based on the received dust concentration data, the control system 100 calculates and outputs corresponding control commands through algorithms to change the speed of the fan motor or the opening of the damper in the settling airflow device 7, thereby changing the downward airflow velocity. The settling airflow device 7 includes a variable frequency fan and a guide duct, thus forming a stable downward airflow field. Using aerodynamic principles, it suppresses the rising dust. In this step, the control logic is set such that the higher the dust concentration, the higher the frequency command output by the control module, driving the fan to accelerate and increase the airflow; conversely, when the dust concentration decreases, the fan decelerates. Through this dynamic adjustment method, the settling airflow device 7 can always maintain an airflow intensity slightly higher than the critical velocity of dust rising, ensuring both dust removal efficiency and avoiding energy waste under low dust conditions.

[0068] Specifically, a positive correlation indicates a functional mapping between the two, meaning that as dust concentration increases, the settling airflow velocity also increases. This can be achieved, for example, through a linear formula V=k×C+b or a piecewise step function, where V represents airflow velocity, C represents dust concentration, k is the gain coefficient, and b is the base wind speed. This balances dust removal efficiency with equipment energy consumption. In the initial stage of pulverization or when processing materials that easily generate large amounts of dust, high-concentration dust exhibits stronger Brownian motion and a tendency to rise. In this case, greater airflow energy is needed to overcome the buoyancy and turbulence interference of the dust, forcing it to settle. Conversely, in the final stage of pulverization or when processing materials with less dust, a lower airflow velocity is sufficient to complete the settling task. Reducing the wind speed significantly reduces fan noise and energy consumption. For example, the system can be set to maintain a minimum base wind speed to prevent airflow stagnation when the dust concentration is below the threshold Cmin; and to operate the fan at full speed to achieve maximum dust removal capacity when the concentration exceeds the threshold Cmax. Through the close cooperation between the dust concentration sensor and the settling airflow device 7, intelligent control of on-demand air supply is realized, which not only improves the equipment's adaptability to the crushing process of different medicine container materials, but also extends the service life of moving parts such as fans and reduces the overall operating cost.
