Description

Technical Field

[0001] This utility model relates to the technical field of medical waste treatment equipment, and more specifically, to a non-contact opening structure and medical waste treatment equipment. Background Technology

[0002] With the continuous increase in the total number of medical and health institutions, beds, and outpatient visits nationwide, the amount of medical waste generated is also increasing. Medical waste carries pathogens and infectious substances, and improper handling can pose a serious threat to public health. Currently, centralized disposal is the common practice for medical waste treatment, but this approach has shortcomings. For example, small medical institutions in remote areas and rural villages are far away and generate small amounts of waste, leading to high logistics costs and increased risk of infection due to untimely collection. In-situ disinfection facilities, on the other hand, can accommodate small medical institutions such as clinics and health centers.

[0003] Medical waste refers to waste generated by medical and health institutions during medical treatment, prevention, health care and other related activities that has direct or indirect infectiousness, toxicity and other hazards.

[0004] Existing medical waste treatment equipment includes a disinfection chamber and a chamber cover. When treating waste, staff usually manually open the chamber cover and then put the packaged medical waste into the disinfection chamber for disinfection.

[0005] Manually opening the cargo cover has many problems, such as: First, staff members will come into close contact with sources of infection from medical waste, which may pose a threat to their safety. Improper handling may cause mechanical damage.

[0006] Second, manually opening the lid can also lead to low efficiency.

[0007] Third, the existing opening mechanism is affected by the height of the equipment installation and handling room, which makes it impossible to open the silo cover, resulting in inconvenience and incomplete feeding.

[0008] Fourth, improper manual closing of the cover leads to poor sealing. Utility Model Content

[0009] The purpose of this invention is to provide a non-contact opening structure and medical waste treatment equipment, which can solve the above-mentioned technical problems.

[0010] In the first aspect, this utility model provides a non-contact opening structure, including a frame, a translation drive assembly, a lid fixing frame, and a vertical drive assembly; The frame is provided with a track groove, which is used to limit the movement trajectory of the cover fixing frame; The translation drive assembly is disposed outside the frame, and the cover fixing frame is disposed inside the frame; The output end of the translation drive component passes through the track groove and is connected to the cover fixing frame. The translation drive component is used to drive the cover fixing frame to translate along the set trajectory of the track groove. The bin cover fixing bracket is used to fix and connect the bin cover; The vertical drive assembly is mounted on the frame and is used to fix the bin cover fixing frame or bin cover.

[0011] In an optional embodiment, the translation drive assembly is a hydraulic cylinder or a pneumatic cylinder.

[0012] In an optional embodiment, the vertical drive component is a hydraulic cylinder or a pneumatic cylinder.

[0013] In an optional embodiment, a limiting device is provided on the frame to limit the position of the cover fixing frame or the cover when the cover is pressed.

[0014] In an optional embodiment, the limiting device is a pneumatic cylinder or a hydraulic cylinder, and the output end of the limiting device is connected to the vertical drive assembly to limit the return of the vertical drive assembly.

[0015] In an optional implementation, the number of the limiting devices is two; The two limiting devices are respectively located on opposite sides of the compartment cover.

[0016] In an optional embodiment, the number of translation drive components is two, and the two translation drive components are respectively disposed at opposite ends of the outer side of the frame; The number of vertical drive components is two, and the two vertical drive components are respectively arranged at opposite ends of the inner side of the frame.

[0017] In an optional embodiment, a dustproof plate for the exhaust port is also included; The exhaust port dustproof plate is installed at the end of the exhaust pipe of the compartment cover.

[0018] In an optional embodiment, the exhaust port dustproof plate is mounted on the frame via a moving device.

[0019] Secondly, this utility model provides a medical waste treatment device, including the non-contact opening structure described in any of the foregoing embodiments.

[0020] The beneficial effects of this utility model are: The automated translation and fixing mechanism drives the lid fixing frame and the lid's translation and vertical drive components to fix the lid, eliminating the need for manual contact with the lid throughout the process. This completely avoids close contact between personnel and the source of infection from medical waste, and also prevents mechanical damage caused by improper manual operation, significantly improving operational safety. The automated translation and fixing actions replace manual lid opening, eliminating tedious manual steps and significantly improving opening efficiency. The lid opens and closes by translating along the frame track groove via the translation drive component, eliminating the dependence of traditional lid opening mechanisms on the height of the equipment installation room, effectively solving the problems of lids being unable to open due to height limitations, and inconvenient and incomplete material feeding. At the same time, the fixing effect of the vertical drive component on the lid fixing frame or the lid ensures that the lid is accurately positioned, avoiding poor sealing caused by incomplete manual closing, and ensuring the sealing reliability of the disinfection chamber.

[0030] The following is combined with Figures 1-4 The following describes some embodiments of the present invention in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] Firstly, this utility model provides a non-contact opening structure, such as... Figures 1-3As shown, the device includes a frame 1, a translation drive assembly 2, a cover fixing frame 4, and a vertical drive assembly 3. The frame 1 has a track groove 10, which defines the movement trajectory of the cover fixing frame 4. The translation drive assembly 2 is located outside the frame 1, and the cover fixing frame 4 is located inside the frame 1. The output end of the translation drive assembly 2 passes through the track groove 10 and connects to the cover fixing frame 4. The translation drive assembly 2 drives the cover fixing frame 4 to translate along the predetermined trajectory of the track groove 10. The cover fixing frame 4 is used to fix a cover 9. The vertical drive assembly 3 is located on the frame 1 and is used to fix the cover fixing frame 4 or the cover 9.

[0032] In this embodiment, the non-contact opening structure consists of a frame 1, a translation drive assembly 2, a lid fixing frame 4, and a vertical drive assembly 3.

[0033] The frame 1 serves as the overall supporting foundation, providing an installation reference for other components. A track groove 10, penetrating both the inside and outside of the frame 1, is provided on the frame 1. The track groove 10 must be compatible with the output end of the translation drive assembly 2 and the movement trajectory of the cover fixing frame 4, ensuring that the cover fixing frame 4 moves smoothly without jamming when driven by the translation drive assembly 2. In other words, the frame 1 can support all components and define their movement trajectory, while the track groove 10 provides guidance for the translation of the cover fixing frame 4, preventing deviation.

[0034] The function of the translation drive component 2 is to output power to drive the cover fixing frame 4 and the cover 9 to translate along the track groove 10, so that the cover 9 moves away from or closer to the inlet of the disinfection chamber, replacing the manual opening action. It is installed on the outside of the frame 1 to avoid interference with the movement of the cover fixing frame 4 and the cover 9 inside the frame 1; its output end passes through the track groove 10 and connects to the cover fixing frame 4. The connection part must be rigid to prevent loosening during translation.

[0035] The function of the cover fixing bracket 4 is to connect the translation drive component 2 and the cover 9, transmit translational force, and ensure that the cover 9 is installed firmly to prevent it from falling off or shifting during movement. Specifically, the cover fixing bracket 4 is located inside the frame 1, and its shape must match the cover 9. It is fixed to the cover 9 by bolts and other connecting parts 11 to ensure that the cover 9 moves synchronously with the fixing bracket.

[0036] The function of the vertical drive component 3 is to apply pressure to the cover fixing frame 4 or the cover 9 when the cover 9 moves directly above the disinfection chamber, pressing the cover 9 tightly onto the disinfection chamber to achieve a seal and avoid the problem of manual incomplete closing. The vertical drive component 3 is installed on the frame 1, and the installation position must correspond to the force points of the cover fixing frame 4 or the cover 9 to ensure uniform pressure when fixing the cover 9.

[0037] In this embodiment, when it is necessary to open the bin cover 9, the staff issues an opening command through the control system. The vertical drive component 3 drives the bin cover fixing frame 4 to rise, opening the bin cover 9. Then, the translating drive component 2 moves the opened bin cover 9 away. When it is necessary to close the bin cover 9, the staff issues a closing command through the control system. The translating drive component 2 moves the bin cover fixing frame 4 to the bin opening, aligning the bin cover 9 with the bin opening. Then, the vertical drive component 3 is activated, driving the bin cover fixing frame 4 to descend, thus closing the bin cover 9.

[0038] Throughout the entire process, no staff need to approach the cover 9; the entire operation is handled through the control system, making it suitable for the automated processing needs of small medical institutions.

[0039] In an optional embodiment, the translation drive component 2 is a hydraulic cylinder or a pneumatic cylinder.

[0040] In this embodiment, the translation drive component 2 is a hydraulic cylinder or a pneumatic cylinder.

[0041] If it is a hydraulic cylinder, its structure includes a cylinder body, a piston rod, an oil inlet and an oil outlet. The cylinder body is fixed on the outside of the frame 1, and the piston rod, as the output end, passes through the track groove 10 and is connected to the cover fixing frame 4. The cylinder body must have sufficient strength to withstand the reaction force during translation and have good sealing performance to prevent hydraulic oil leakage.

[0042] If it is a cylinder, the structure includes a cylinder body, piston rod, air inlet and exhaust port. The cylinder body is installed on the outside of the frame 1, and the piston rod is connected to the cover fixing bracket 4. The cylinder body material must be corrosion resistant and meet the hygiene requirements of the medical environment. At the same time, it must be equipped with pneumatic components (such as solenoid valves) to control the airflow direction.

[0043] The connection between the output end of both drive components and the cover fixing frame 4 should be a detachable structure (such as a flange connection) to facilitate future maintenance and replacement.

[0044] When a hydraulic cylinder is used as the translation drive component 2, oil is supplied to the cylinder inlet via a hydraulic system. The hydraulic oil pushes the piston rod to extend or retract, causing the cover fixing frame 4 to translate. Its core function is to provide a large driving force, suitable for medical waste treatment equipment with heavy covers 9. It ensures a smooth translation process with sufficient power, avoiding translation jamming due to the excessive weight of the cover 9. When a pneumatic cylinder is used as the translation drive component 2, air is supplied to the cylinder inlet via a pneumatic system. Compressed air pushes the piston rod to extend and retract, realizing the translation of the cover fixing frame 4. Its features include fast response speed, rapid start and stop, suitable for scenarios requiring quick cover opening and closing. Furthermore, the pneumatic cylinder has a simple structure and low maintenance cost, reducing the equipment operation and maintenance pressure of small medical institutions. Both drive components can replace manual labor to provide translational force, realizing the core function of non-contact cover opening. Selecting different types according to equipment requirements can improve the adaptability of the structure.

[0045] It is understood that in this embodiment, the translation drive component 2 is a hydraulic cylinder or a pneumatic cylinder, but it is not limited to hydraulic cylinders or pneumatic cylinders. It can also be other power structures, such as an electric push rod. Its structure includes a motor, a lead screw, and a push rod. The motor drives the lead screw to rotate, which drives the push rod to extend and retract, thereby realizing the translation of the cover fixing frame 4. The electric push rod does not require hydraulic oil or compressed air, but only electric power. It is suitable for scenarios without hydraulic or pneumatic systems, and has high control precision, enabling precise translation position control. It can also be replaced by a linear motor, which drives the mover (connected to the cover fixing frame 4) to translate along the stator (mounted on the frame 1) through electromagnetic induction. In other words, as long as it can drive the cover fixing frame 4 and the cover 9 to perform linear translation, it is acceptable.

[0046] In an optional embodiment, the vertical drive component 3 is a hydraulic cylinder or a pneumatic cylinder.

[0047] In this embodiment, the vertical drive component 3 is defined as a hydraulic cylinder or a pneumatic cylinder.

[0048] If a hydraulic cylinder is used, its structure includes a cylinder body, piston rod, oil inlet, and oil return. The cylinder body is fixed to the frame 1, and the piston rod faces the cover fixing bracket 4 or the cover 9. The cylinder body must be installed vertically to ensure that the piston rod can apply vertical pressure, and the cylinder body's pressure resistance must meet the standards to prevent damage under pressure. If a pneumatic cylinder is used, its structure consists of a cylinder body, piston rod, air inlet, and air outlet. The cylinder body is installed on the frame 1, and the piston rod is aligned with the force point of the cover fixing bracket 4 or the cover 9. The cylinder body must have good sealing performance to prevent compressed air leakage from affecting the clamping effect. At the same time, a buffer pad can be added to the end of the piston rod to prevent mechanical damage to the cover 9 during clamping.

[0049] The connection between the cylinder body and frame 1 of both drive components must be firm, which can be achieved by bolting or welding to prevent cylinder body displacement during operation, which would cause the clamping force to shift.

[0050] When the hydraulic cylinder is used as the vertical drive component 3, its core function is to provide a stable and large vertical clamping force. When the cover 9 is moved directly above the disinfection chamber, the hydraulic cylinder is activated, and the piston rod extends downward, applying pressure to the cover fixing bracket 4 or the cover 9, ensuring a tight fit between the cover 9 and the disinfection chamber. This is particularly suitable for scenarios where the cover 9 is lightweight or where the disinfection chamber has high sealing requirements. The large clamping force effectively improves sealing performance and prevents exhaust gas leakage during disinfection. When the pneumatic cylinder is used as the vertical drive component 3, its function is to quickly provide vertical clamping force. Compressed air drives the piston rod to extend quickly, shortening the sealing preparation time after closing the cover and improving the overall processing efficiency of the equipment. Furthermore, the clamping force of the pneumatic cylinder can be controlled by adjusting the air pressure, making it suitable for clamping requirements of cover 9 of different thicknesses or materials, avoiding damage to the cover 9 due to excessive clamping force or poor sealing due to insufficient clamping force. Both drive components can replace the pressing action when manually closing the cover, functionally solving the problem of inaccurate manual closing and ensuring a reliable sealing effect every time the cover is closed.

[0051] Similarly, it is understandable that, in addition to hydraulic cylinders and air cylinders, the vertical drive component 3 can also be a linear displacement structure using a motor, such as a gear and rack structure or a threaded screw structure, as long as it can drive the cover fixing frame 4 and the cover 9 to move up and down in the vertical direction.

[0052] In an optional embodiment, a limiting device 5 is provided on the frame 1 to limit the position of the cover fixing frame 4 or the cover 9 when the cover 9 is pressed.

[0053] In this embodiment, a limiting device 5 is added to the frame 1 to limit the bin cover fixing frame 4 or bin cover 9 when the bin cover 9 is pressed.

[0054] Specifically, after the vertical drive assembly 3 pushes down the cover fixing frame 4 and the cover 9, the cover 9 can be fixed and positioned to a certain extent by the vertical drive assembly 3. Since a large air pressure may be generated inside the medical waste during processing, thus exerting an outward force on the cover 9, to prevent excessive force from damaging the vertical drive assembly 3 and to prevent the cover 9's sealing performance from being compromised, the limiting device 5 physically limits the cover fixing frame 4, the cover 9, or the vertical drive assembly 3, increasing the force exerted by the vertical drive assembly 3 when fixing the cover 9 and ensuring the sealing performance of the cover 9.

[0055] There are many ways to set the limiting device 5. For example, it can be a limiting pin set on the frame 1, that is, when the cover 9 is pressed, the limiting pin passes through the frame 1 and inserts into the cover fixing frame 4 above the cover 9 to limit the cover fixing frame 4 in the vertical direction; it can also be a snap-fit ​​structure, that is, when the cover 9 is pressed, the snap-fit ​​fastens the cover 9 to achieve locking and limiting of the cover 9, etc. In other words, as long as the limiting device 5 can limit the cover 9 and ensure the sealing performance of the cover 9, it is acceptable.

[0056] In an optional embodiment, the limiting device 5 is a cylinder or a hydraulic cylinder, and the output end of the limiting device 5 is connected to the vertical drive assembly 3 to limit the return of the vertical drive assembly 3.

[0057] In this embodiment, the vertical drive component 3 is a cylinder, referred to as the vertical drive cylinder, and the limiting device 5 is a cylinder, referred to as the limiting cylinder. This will be used as an example for explanation.

[0058] like Figure 4 As shown, the end of the vertical drive cylinder has a connector 11 that connects to the cover fixing bracket 4.

[0059] When the vertical drive cylinder moves the cover fixing bracket 4 downwards to install the cover 9, the vertical drive cylinder stops and maintains pressure on the cover 9. At this time, the limit cylinder is activated, and its piston rod extends and inserts into the end of the vertical drive cylinder, abutting against the side of the connector 11 closest to the vertical drive cylinder. This prevents the connector 11 from moving upwards under the action of the cover 9, thus limiting the position of the connector 11 and maintaining pressure on the cover 9.

[0060] Similarly, the limit device 5 can also be a hydraulic cylinder, and its usage is the same.

[0061] In an optional embodiment, the number of the limiting devices 5 is two; the two limiting devices 5 are respectively arranged on opposite sides of the compartment cover 9.

[0062] In this embodiment, the number of limiting devices 5 is limited to two, and they are respectively set on opposite sides of the cover 9. The two limiting devices 5 need to be installed symmetrically. When the frame 1 is rectangular, the opposite sides are usually the left and right sides or the front and back sides. The installation position of the limiting devices 5 needs to correspond to the force points of the cover fixing frame 4 or the cover 9 to ensure that the limiting force on both sides is uniform.

[0063] The connection structure between the limiting device 5 and the frame 1 must be symmetrical and the connection strength must be consistent to prevent loosening on one side from causing the limiting device to shift. At the same time, the distance between the two limiting devices 5 must be adapted to the spacing between the opposite sides of the cover 9 to ensure that they can contact the cover fixing frame 4 or the cover 9 simultaneously to achieve synchronous limiting.

[0064] Two symmetrically arranged limiting devices 5 can ensure balanced limiting of the cover fixing frame 4 or the cover 9, avoiding uneven force caused by unilateral limiting. When the vertical drive component 3 applies a pressing force to the cover 9, if the limiting device 5 is only set on one side, the cover fixing frame 4 or the cover 9 will tilt due to the force on one side, resulting in uneven contact between the cover 9 and the disinfection chamber, and some areas will not be sealed tightly. However, the two limiting devices 5 on opposite sides can simultaneously apply a blocking force to the cover fixing frame 4 or the cover 9, so that the force on the components is evenly distributed in the vertical direction, ensuring that the cover 9 fits flat against the disinfection chamber and improving the overall sealing effect.

[0065] In addition, symmetrical limiting can prevent the cover fixing frame 4 or the cover 9 from horizontally shifting during the limiting process, ensuring the positional accuracy of the cover 9 each time it is closed, avoiding misalignment between the cover 9 and the disinfection chamber due to shifting, and further improving the stability of equipment operation.

[0066] At the same time, the two limit devices 5 can form a double protection. If one of the limit devices 5 has a minor malfunction, the other can still play a certain limiting role, reducing the risk of equipment failure due to limit failure.

[0067] It is understood that in this embodiment, the number of limiting devices 5 is two, but it is not limited to two; there can be more, as long as they are evenly arranged around the bin cover 9 to ensure that the bin cover 9 is subjected to balanced force.

[0068] In an optional embodiment, there are two translation drive components 2, which are respectively disposed at opposite ends on the outer side of the frame 1; and there are two vertical drive components 3, which are respectively disposed at opposite ends on the inner side of the frame 1.

[0069] In this embodiment, the translation drive component 2 is set on the track groove 10 of the frame 1, and the extended end passes through the track groove 10 and is connected to the vertical drive component 3. The lower end of the vertical drive component 3 is connected to the cover fixing frame 4, and the cover fixing frame 4 is connected to the cover 9.

[0070] The translation drive component 2 and the vertical drive component 3 together constitute the moving component. In this embodiment, there are two sets of moving components, which are respectively set on opposite sides of the frame 1 and can be connected to opposite ends of the cover 9. A synchronization structure can be set between the two vertical drive components 3 to ensure the balance of the cover 9 during the opening and closing process.

[0071] Similarly, in this embodiment, the track grooves 10 on the frame 1 are also arranged opposite to each other, and the track grooves 10 on both sides are exactly the same.

[0072] Specifically, in this embodiment, to ensure the stability of the output end of the translation drive assembly 2 during the translation process, there are two track grooves 10 on the same side. The piston rod end of the translation drive cylinder has two protruding ends, which are fixedly connected to the cylinder body of the vertical drive cylinder by passing through the two track grooves 10 respectively. This can prevent the vertical drive cylinder from shaking during the translation process and ensure that the force of the vertical drive cylinder is in the vertical direction, thereby ensuring the stability and accuracy of the opening and closing process of the cover 9.

[0073] In an optional embodiment, a dustproof plate 7 for the exhaust port is also included; the dustproof plate 7 for the exhaust port is disposed at the end of the exhaust pipe 6 of the cover 9.

[0074] In this embodiment, the cover 9 is provided with an exhaust port to release pressure before opening the cover, so as to ensure safety when opening the cover.

[0075] To prevent harmful impurities inside the equipment from being discharged through the exhaust port during the pressure relief process, a filter screen is installed at the exhaust port; at the same time, to ensure the stability of the internal pressure of the equipment during use, the exhaust port needs to be sealed.

[0076] In this embodiment, a dustproof plate 7 for the exhaust port is provided, which is located at the end of the exhaust pipe 6 and can seal the exhaust port.

[0077] In an optional embodiment, the exhaust port dustproof plate 7 is mounted on the frame 1 via a moving device 8.

[0078] In this embodiment, the exhaust port dustproof plate 7 is mounted on the frame 1 by a moving device 8. When needed, it moves to the exhaust port to seal the exhaust port. When pressure relief is required, the exhaust port dustproof plate 7 is moved out of the exhaust port.

[0079] Specifically, in this embodiment, the moving device 8 is a cylinder.

[0080] More specifically, one end of the piston rod of the cylinder is fixedly connected to the end of the exhaust port dustproof plate 7, and the cylinder body is fixedly mounted on the frame 1. The movement of the piston rod drives the exhaust port dustproof plate 7 to make linear displacement.

[0081] It is understandable that the moving device 8 can be a cylinder, but it is not limited to a cylinder. It can also be other devices that can move linearly, such as a hydraulic cylinder, or a motor with a linear transmission mechanism, as long as it can drive the exhaust port dustproof plate 7 to move linearly and can seal the exhaust port of the exhaust pipe 6.

[0082] Secondly, this utility model provides a medical waste treatment device, including the non-contact opening structure described in any of the foregoing embodiments.

[0083] The beneficial effects of this utility model embodiment are: The translation drive assembly 2 moves the cover fixing frame 4 and the cover 9 horizontally, while the vertical drive assembly 3 fixes the cover 9 in place. The entire process eliminates the need for manual contact between personnel and the cover 9, completely preventing close contact between personnel and the source of infection from medical waste. It also prevents mechanical damage caused by improper manual operation, significantly improving operational safety. The automated translation and fixing actions replace manual opening, eliminating tedious manual steps and significantly improving opening efficiency. The cover 9 opens and closes by moving along the track groove 10 of the frame 1 via the translation drive assembly 2, eliminating the dependence of traditional cover opening mechanisms on the height of the installation room. This effectively solves the problems of the cover 9 being unable to open due to height limitations, and the inconvenience and incomplete feeding of materials. Simultaneously, the fixing effect of the vertical drive assembly 3 on the cover fixing frame 4 or the cover 9 ensures precise positioning of the cover 9, avoiding poor sealing caused by incomplete manual closing and guaranteeing the sealing reliability of the disinfection chamber.

[0084] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
