Description
Technical Field
[0001] This utility model relates to the field of steam sterilization technology, and in particular to a vertical pressure steam sterilizer. Background Technology
[0002] A vertical pressure steam sterilizer is a device that uses pressurized saturated steam to disinfect and sterilize items. It typically consists of a shell, steam generator, control system, safety valve, temperature sensor, pressure gauge, inlet valve, and exhaust valve. It features high-efficiency sterilization, high safety, simple operation, energy saving and environmental protection, and strong adaptability. It is widely used in medical and health, scientific research, and agricultural fields, and can disinfect and sterilize a variety of items such as medical devices, dressings, glassware, and solution culture media.
[0003] In existing technologies, some pressure steam sterilizers are often used by operators who simply place the materials directly onto the sterilization rack and then start the sterilization process. However, the sterilization rack position of these sterilizers is fixed and cannot be flexibly changed according to sterilization needs. This results in the steam failing to cover every part of the material completely and without dead angles during sterilization, especially at the edges and corners of the sterilization rack and the inner layers of multi-layered materials, often leading to incomplete sterilization and seriously affecting the sterilization effect and quality. To address these problems, a vertical pressure steam sterilizer is proposed. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a vertical pressure steam sterilizer, which aims to improve the problem that in the existing technology, the sterilization of materials at the edges and corners of the sterilization rack and the inner layers of multi-layered stacked materials is often incomplete, which seriously affects the sterilization effect and quality.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A vertical pressure steam sterilizer includes a sterilization chamber, a protective box fixedly connected to the bottom of the sterilization chamber, a motor fixedly connected to the inner wall of the bottom end of the protective box, a turntable fixedly connected to the drive end of the motor, an adjustment component provided on the outside of the turntable, a connecting column rotatably connected to the inner wall of the bottom end of the sterilization chamber, a rotating plate fixedly connected to the outside of the connecting column, a sterilization rack fixedly connected to the top of the connecting column, and an installation component provided inside the sterilization rack.
[0007] As a further description of the above technical solution:
[0008] The adjustment assembly includes a lever, one end of which is fixedly connected to the outside of the turntable, and the other end of which is rotatably connected to a roller. The turntable has multiple grooves on its outside.
[0009] As a further description of the above technical solution:
[0010] The turntable is externally slidably connected to the outside of the rotating plate, and the roller is externally rotatably connected to the inner wall of the groove;
[0011] As a further description of the above technical solution:
[0012] The disinfection rack has multiple detachable placement plates inside, and the top of each placement plate has multiple sliding grooves. The inner wall of each sliding groove is slidably connected to a push rod.
[0013] As a further description of the above technical solution:
[0014] The installation assembly includes a limiting plate, the top of which is fixedly connected to the bottom of the push rod. The placement plate has multiple cavities inside, and a locking block is fixedly connected to one side of the limiting plate.
[0015] As a further description of the above technical solution:
[0016] A spring is fixedly connected to the side of the limiting plate away from the locking block, and the other end of the spring is fixedly connected to the inner wall of the cavity;
[0017] As a further description of the above technical solution:
[0018] The limiting plate is externally slidably connected to the inner wall of the cavity, and the locking block is externally slidably connected to the inner wall of the cavity;
[0019] As a further description of the above technical solution:
[0020] The disinfection rack has multiple slots inside, and the outer side of the card block engages with the inner wall of the slot. A sealing cover is hinged to the top left side of the disinfection box.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, when the roller enters the inner wall of the groove along with the lever, the lever pushes the rotating plate to rotate around the connecting column, which in turn drives the sterilization rack fixed on the top of the connecting column to rotate intermittently. During the sterilization process, the intermittent rotation of the sterilization rack causes the material placed on it to constantly change position, avoiding the problem that the steam cannot fully cover the material due to the fixed position. The steam can evenly contact all parts of the material, effectively improving the sterilization effect and ensuring that every part of the material can meet the sterilization standard, thus solving the problem of incomplete sterilization of materials in traditional sterilizers.
[0023] 2. In this utility model, when the locking block is aligned with the slot inside the sterilization rack, the push rod is released, the spring returns to its original position, and the limiting plate and the locking block are engaged with the slot, thereby fixing the placement plate inside the sterilization rack. If the position of the placement plate needs to be adjusted, the push rod is moved again to disengage the locking block from the slot. This allows the sterilizer to adapt to different quantities and heights of items to be sterilized, improving the versatility and practicality of the equipment and meeting diverse sterilization needs.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1 to 2The present invention provides an embodiment of a vertical pressure steam sterilizer, comprising a sterilization chamber 1, which is the core of the entire sterilizer. A protective chamber 2 is fixedly connected to the bottom of the sterilization chamber 1, and a motor 3 is fixedly connected to the inner wall of the bottom of the protective chamber 2. The protective chamber 2 can effectively prevent external objects from colliding and damaging the internal motor 3, and also has a certain heat insulation performance. The motor 3 is the power source for the entire sterilizer to realize the material rotation function.
[0033] A turntable 4 is fixedly connected to the drive end of motor 3. A triangular groove is provided on the outside of turntable 4. An adjustment component is provided on the outside of turntable 4. The adjustment component includes a lever 5. One end of lever 5 is fixedly connected to the outside of turntable 4, and the other end of lever 5 is rotatably connected to roller 6. A connecting column 7 is rotatably connected to the inner wall of the bottom end of disinfection box 1. A rotating plate 8 is fixedly connected to the outside of connecting column 7. The outside of turntable 4 is slidably connected to the outside of rotating plate 8. Rotating plate 8 rotates outside of the triangular groove, but the triangular groove does not interfere with the rotation trajectory of rotating plate 8. The surface of turntable 4 is finely processed and has high flatness and smoothness to ensure smooth power transmission when in contact with rotating plate 8.
[0034] The roller 6 reduces friction when the lever 5 pushes the rotating plate 8, making the rotation of the rotating plate 8 smoother. It also reduces wear on the surfaces of the lever 5 and the rotating plate 8, extending the service life of related components. The rotating plate 8 has multiple grooves 9 on its outer side. The outer side of the roller 6 is rotatably connected to the inner wall of the groove 9, which can evenly transmit the thrust of the lever 5 and roll flexibly in the groove 9 during the rotation of the rotating plate 8.
[0035] The inner wall of the groove 9 provides good guidance and constraint for the roller 6 and the lever 5, ensuring that the rotating plate 8 can rotate in a predetermined direction and angle during the rotation of the turntable 4, thus realizing the intermittent rotation function of the connecting column 7. A sterilization rack 10 is fixedly connected to the top of the connecting column 7. The sterilization rack 10 has a spacious interior, which is convenient for placing materials of different shapes and sizes. The top of the connecting column 7 and the sterilization rack 10 are fixed together by welding to ensure that there is no relative displacement between the two during rotation, thereby achieving the purpose of smoothly transmitting the rotation of the rotating plate 8 to the sterilization rack 10.
[0036] Reference Figures 3 to 5 The disinfection rack 10 has multiple detachable placement plates 11 inside. The placement plates 11 are used to place materials to be sterilized. The top of the placement plate 11 has multiple sliding grooves 12. The inner wall of the sliding groove 12 is slidably connected to a push rod 13. Through the cooperation of the sliding groove 12 and the push rod 13, the adjustable installation function of the placement plate 11 inside the disinfection rack 10 is realized.
[0037] The disinfection rack 10 has an internal installation assembly, including a limiting plate 15. The top of the limiting plate 15 is fixedly connected to the bottom of the push rod 13. The placement plate 11 has multiple cavities 14 inside. The outer side of the limiting plate 15 is slidably connected to the inner wall of the cavity 14. When the operator moves the push rod 13, the push rod 13 can slide along the inner wall of the sliding groove 12, thereby driving the limiting plate 15 to move within the cavity 14. A spring 16 is fixedly connected to the side of the limiting plate 15 away from the locking block 17. The other end of the spring 16 is fixedly connected to the inner wall of the cavity 14. One end of the cavity 14 is connected to the sliding groove 12, so that the push rod 13 can drive the limiting plate 15 to move within the cavity 14.
[0038] The other end of the cavity 14 is closed, providing a fixed support point for the spring 16. A locking block 17 is fixedly connected to one side of the limiting plate 15. When the push rod 13 is moved, the limiting plate 15 slides within the cavity 14 along with the push rod 13, causing the locking block 17 and the spring 16 to move together. During the installation of the placement plate 11, when the push rod 13 is moved, causing the locking block 17 to enter the cavity 14, the spring 16 is compressed, storing elastic potential energy. The locking block 17 is externally slidably connected to the inner wall of the cavity 14.
[0039] The sterilization rack 10 has multiple slots 18 inside. When the placement plate 11 is installed on the sterilization rack 10, the locking block 17 enters the slot 18 under the action of the limiting plate 15, thus fixing the placement plate 11 to the sterilization rack 10. When it is necessary to adjust the position of the placement plate 11, the operator can move the push rod 13 to disengage the locking block 17 from the slot 18 for easy position adjustment. The outer side of the locking block 17 engages with the inner wall of the slot 18. A sealing cover 19 is hinged to the top left side of the sterilization chamber 1. The function of the sealing cover 19 is to seal the internal space of the sterilization chamber 1 when the sterilizer is working, prevent steam leakage, and ensure the high temperature and high pressure conditions of the sterilization environment.
[0040] Working principle: First, place the sterilization box 1 in a suitable position, then open the sealing cover 19 and place the placement plate 11 inside the sterilization rack 10. Move the push rod 13, and the push rod 13 slides along the inner wall of the sliding groove 12. At this time, the limiting plate 15 will slide on the inner wall of the cavity 14 with the push rod 13, causing the spring 16 to be compressed. At this time, the locking block 17 enters the cavity 14. Align the locking block 17 with the locking slot 18 and release the push rod 13. At this time, the spring 16 is no longer compressed and returns to its original position due to its elastic properties, generating a reaction force on the limiting plate 15. At the same time, the locking block 17 enters the inner wall of the locking slot 18 and engages with it, thereby fixing the placement plate 11 inside the sterilization rack 10. The quantity and height of the items to be sterilized can be adjusted as needed.
[0041] Then, start motor 3. Driven by motor 3, turntable 4 rotates. When turntable 4 rotates, it will contact the outside of turntable 8. At this time, connecting column 7 will not rotate. When the outside of roller 6 enters the inner wall of groove 9, lever 5 will also enter the inner wall of groove 9 along with the rotation of turntable 4. When turntable 4 rotates, it will push turntable 8 to rotate, thereby realizing the intermittent rotation of connecting column 7. When connecting column 7 rotates, it will drive disinfection rack 10 to rotate.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
