Description

Technical Field

[0001] The utility model relates to the technical field of sterilizers, in particular to a dual-path high-temperature sterilizer. Background Technique

[0002] A sterilizer, as a precision-designed disinfection device, its core principle is based on the natural law that bacteria cannot survive in a high-temperature and high-pressure environment. Due to its efficient and reliable disinfection ability, the sterilizer has become an indispensable ideal choice in many fields, especially playing a crucial role in key industries such as medical and health, scientific research, and agricultural food processing. The dual-path high-temperature sterilizer is carefully designed to meet the strict requirements for a sterile environment in industries such as medical treatment, biological research, pharmaceuticals, and food processing. Through a dual-path sterilization system, this device can simultaneously perform efficient and thorough sterilization on different types of items.

[0003] After the existing high-temperature sterilizer completes the sterilization operation, most often it requires operators to manually take out the sterilized objects inside the device in person. This not only increases the labor intensity of the operators but also may pose a potential threat to their health due to frequent contact with the high-temperature environment. Moreover, during the sterilization process, if sudden situations and accidents occur, most of the existing high-temperature sterilizers cannot ensure that the protective door remains closed. Once the protective door is accidentally opened, it may not only damage the airtightness of the sterilization environment and affect the sterilization effect but also directly expose the operators to high temperature, high pressure, and harmful steam, thus triggering serious safety accidents and causing irreversible harm to the health of the personnel.

[0004] Therefore, the technical personnel in this field have provided a dual-path high-temperature sterilizer to solve the problems raised in the above background technique. Content of the Utility Model

[0006] A dual-path high-temperature sterilizer includes a device main body. An extending mechanism is arranged inside the device main body. The extending mechanism includes two sterilization frames, two first racks, two first gears, two second gears, two second racks, two compression springs, and two fixing rods. Placement plates are slidably arranged inside both of the two sterilization frames. An air inlet pipe is fixedly arranged on one side of the device main body. The output end of the air inlet pipe is fixedly provided with an electromagnetic valve, and air delivery pipes are respectively fixedly arranged at the upper and lower ends of the electromagnetic valve;

[0007] Two protective doors are hinged at the front end of the device main body. Fixed blocks are fixedly arranged at the rear ends of the two protective doors. A safety mechanism is arranged inside the device main body. The safety mechanism includes two through holes, two fixed frames, two connecting rods, two springs and two clamping blocks.

[0008] Preferably, the outsides of the two sterilization frames are fixedly arranged inside the device main body. The outer parts of the two first racks are respectively slidably arranged at the upper ends of one side inside the two sterilization frames. The rear ends of the two fixed rods are respectively fixedly arranged at the front ends of the two first racks. The outer parts of the two fixed rods are respectively slidably arranged at the front ends of one side inside the two sterilization frames.

[0009] Preferably, the front ends of the two compression springs are respectively fixedly arranged at the front ends of one side inside the two sterilization frames. The front ends of the two compression springs are respectively fixedly arranged at the front ends of the two first racks. The inner parts of the two compression springs are respectively sleeved on the outer parts of the two fixed rods near the rear ends. The output ends of the two air delivery pipes are respectively fixedly arranged at the other sides inside the two sterilization frames.

[0010] Preferably, the outer parts of the two first gears are respectively rotatably arranged at one side inside the two sterilization frames. The outer parts of the two second gears are respectively rotatably arranged at one side inside the two sterilization frames. The outer parts of the two second gears are respectively meshed and connected to the outer parts of the two first gears. The lower ends of the two second racks are respectively slidably arranged at the lower ends of one side inside the two sterilization frames. One side of each of the two second racks is fixedly arranged at one side of the two placement plates.

[0011] Preferably, the outer parts of the two connecting rods are respectively slidably arranged inside the two fixed frames. The outer parts of the two fixed frames are respectively fixedly arranged at the front ends inside the two sterilization frames. The upper ends of the two springs are respectively fixedly arranged at the upper ends of the outer parts of the two connecting rods. The lower ends of the two springs are respectively fixedly arranged at the lower ends inside the two fixed frames.

[0012] Preferably, the lower ends of the two connecting rods are respectively fixedly arranged at the upper ends of the two clamping blocks. The outer parts of the two clamping blocks are respectively slidably arranged inside the two fixed blocks. The outer parts of the two through holes are respectively opened between the two fixed frames and the two sterilization frames.

[0014] The beneficial effects of the present utility model are embodied in:

[0015] 1. When the protective door is closed, the fixed block moves inside the sterilization frame. Then, high-temperature sterilization gas is introduced into one of the sterilization frames through the air delivery pipe. As the gas fills the sterilization frame, the gas passes through the fine through-holes to the inside of the fixed frame, squeezing the connecting rod to cause it to descend, and making the spring connected to it contract inside the fixed frame, prompting the clamping block at the lower end of the connecting rod to slide down synchronously, thus sliding into the fixed block at the rear end of the protective door and then embedding into the sterilization frame to achieve mechanical locking of the protective door, ensuring the airtightness and safety of the environment during sterilization.

[0016] 2. After sterilization is completed and the gas is completely discharged, the protective door is opened. At this time, the contact between the protective door and the fixed rod is released, and then the compression spring rebounds instantly and pushes the connecting rod to reset. When the connecting rod moves, it will drive the first rack to move synchronously, and promote the first gear to rotate. Immediately, the first gear drives the second gear to rotate. The rotation of the second gear will drive the second rack to slide inside the sterilization frame, thereby prompting the placement plate connected to the second rack and the items it carries to move forward smoothly. This not only enables the items to exit smoothly after sterilization, but also improves the operation efficiency and convenience, and is time-saving and labor-saving.

The following embodiments are only used to illustrate the technical solutions of the present utility model more clearly, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0026] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meanings understood by those skilled in the art to which the present utility model belongs.

[0027] A dual-channel high-temperature sterilizer includes a device main body 1. An extending mechanism 7 is arranged inside the device main body 1. The extending mechanism 7 includes two sterilization frames 701, two first racks 702, two first gears 703, two second gears 704, two second racks 705, two compression springs 706 and two fixing rods 707. Placement plates 8 are slidably arranged inside both of the two sterilization frames 701. An air inlet pipe 6 is fixedly arranged on one side of the device main body 1. The output end of the air inlet pipe 6 is fixedly provided with a solenoid valve 9. The upper and lower ends of the solenoid valve 9 are respectively fixedly provided with air delivery pipes 10. The outsides of both of the two sterilization frames 701 are fixedly arranged inside the device main body 1. The outer parts of the two first racks 702 are respectively slidably arranged at the upper end of one side inside both of the two sterilization frames 701. The rear ends of the two fixing rods 707 are respectively fixedly arranged at the front ends of the two first racks 702. The outer parts of the two fixing rods 707 are respectively slidably arranged at the front end of one side inside both of the two sterilization frames 701. The front ends of the two compression springs 706 are respectively fixedly arranged at the front end of one side inside both of the two sterilization frames 701. The front ends of the two compression springs 706 are respectively fixedly arranged at the front ends of the two first racks 702. The inner parts of the two compression springs 706 are respectively sleeved on the outer parts of the two fixing rods 707 near the rear ends. The output ends of the two air delivery pipes 10 are respectively fixedly arranged at the other side inside both of the two sterilization frames 701. The outer parts of the two first gears 703 are respectively rotatably arranged at the upper end of one side inside both of the two sterilization frames 701. The outer parts of the two second gears 704 are respectively rotatably arranged at the lower end of one side inside both of the two sterilization frames 701. The outer parts of the two second gears 704 are respectively meshed and connected to the outer parts of the two first gears 703. The lower ends of the two second racks 705 are respectively slidably arranged at the lower end of one side inside both of the two sterilization frames 701. One side of each of the two second racks 705 is fixedly arranged on one side of each of the two placement plates 8;

[0028] After sterilization is completed, the exhaust pipe 11 discharges the residual gas inside the sterilization box 701, and then the protective door 2 is opened. At this time, the contact between the protective door 2 and the fixed rod 707 is immediately released. Then, the compression spring 706 inside the sterilization box 701 rebounds, driving the connecting rod 1203 to slide inside the sterilization box 701, causing it to return to its original position. When the fixed rod 707 moves, it will synchronously drive the first rack 702 to move synchronously with it. The sliding of the first rack 702 will be transmitted to the first gear 703, causing the first gear 703 to rotate. Immediately afterwards, the rotation of the first gear 703 will be transmitted to the second gear 704 meshing with it, causing the second gear 704 to rotate. The rotation of the second gear 704 will cause the second rack 705 to slide smoothly inside the sterilization box 701. Finally, the second rack 705 will drive the placement plate 8 and its load connected to it to move forward smoothly inside the sterilization box 701, thus completing the evacuation step of the items after sterilization. This not only enables the automatic withdrawal of the sterilized items, improves the work flow and efficiency, but also reduces the manual operation burden, achieving the goal of saving time and effort. Moreover, the two sterilization boxes 701 can sterilize two groups of items, greatly improving the work efficiency. The space between the sterilization box 701 and the device main body 1 is a vacuum environment, which can improve the overall safety.

[0029] Two protective doors 2 are hinged at the front end of the device main body 1. Fixed blocks 13 are fixedly arranged at the rear ends of the two protective doors 2. A safety mechanism 12 is arranged inside the device main body 1. The safety mechanism 12 includes two through holes 1201, two fixed frames 1202, two connecting rods 1203, two springs 1204 and two clamping blocks 1205. The outer parts of the two connecting rods 1203 are respectively slidably arranged inside the two fixed frames 1202. The outer parts of the two fixed frames 1202 are respectively fixedly arranged at the front ends inside the two sterilization boxes 701. The upper ends of the two springs 1204 are respectively fixedly arranged at the upper ends of the outer parts of the two connecting rods 1203. The lower ends of the two springs 1204 are respectively fixedly arranged at the lower ends inside the two fixed frames 1202. The lower ends of the two connecting rods 1203 are respectively fixedly arranged at the upper ends of the two clamping blocks 1205. The outer parts of the two clamping blocks 1205 are respectively slidably arranged inside the two fixed blocks 13. The outer parts of the two through holes 1201 are respectively opened between the two fixed frames 1202 and the two sterilization boxes 701;

[0030] When performing the sterilization operation, the protective door 2 hinged at the front end of the device main body 1 is closed. The rear end of the protective door 2 has a sealing strip. When closed, due to the sealing performance, at this time, the fixed block 13 at the rear end of the protective door 2 moves to the inside of the sterilization frame 701. At this time, the sterilization starts. By introducing high-temperature sterilization gas and activating the solenoid valve 9, the gas enters through and reaches an air delivery pipe 10, and then enters the inside of a sterilization frame 701. Subsequently, the exhaust gas is discharged through the exhaust pipe 11 inside the sterilization frame 701 to form a continuous cycle, thereby comprehensively sterilizing the items above the placement plate 8. As the gas fills the sterilization frame 701, the gas will be transmitted to the inside of the fixed frame 1202 through the through hole 1201, and push the connecting rod 1203 to slide inside the fixed frame 1202. As a result, the spring 1204 at its lower end is stressed and contracts, and the block 1205 connected to the connecting rod 1203 is pressed to slide downward, slide into the fixed block 13, and embed into the inside of the sterilization frame 701, thereby realizing the locking of the protective door 2, ensuring the airtightness and safety inside the sterilization frame 701 during sterilization. If an attempt is made to open the protective door 2 during the sterilization process, the safety mechanism 12 will prevent the door from opening, preventing high-temperature steam from leaking and ensuring the safety of the operator.

[0031] Four universal wheels 3 are fixedly arranged at the lower end of the device main body 1. The universal wheels 3 enable the entire device to be easily moved to the required position, improving the flexibility of use. A control panel 4 is fixedly arranged at the front end of the device main body 1. The control panel 4 enables the user to conveniently control various operations of the device, with convenient operation. A pressure relief valve 5 is fixedly arranged outside the air inlet pipe 6. The pressure relief valve 5 can automatically release pressure when the pressure inside the device main body 1 is abnormal, ensuring the safe operation of the device, thereby extending the service life of the device. Exhaust pipes 11 are fixedly arranged on one side of each of the two sterilization frames 701. The exhaust pipes 11 facilitate the discharge of the gas generated during the sterilization process, maintaining the cleanliness and efficiency of the sterilization environment, and maintaining the pressure balance inside the sterilization frame 701. When the sterilization cycle ends, the solenoid valve 9 is closed, and the high-temperature gas inside the sterilization frame 701 is discharged through the exhaust pipe 11 to achieve rapid cooling.

[0032] Working principle: When the protection door 2 is closed, the fixed block 13 moves into the sterilization frame 701 along with the protection door 2. During sterilization, high-temperature gas enters the air inlet pipe 6, and then the solenoid valve 9 is activated, enabling the high-temperature gas to enter into a sterilization frame 701 through a gas delivery pipe 10 and be discharged through the exhaust pipe 11. This cycle is repeated to achieve the sterilization operation on the objects at the upper end of the placement frame. When the sterilization frame 701 is filled with gas, the gas will enter into the fixed frame 1202 through the through hole 1201, thereby squeezing the connecting rod 1203 and the spring 1204, causing the latch block 1205 to move downward and slide into the fixed block 13, and then inserting into the sterilization frame 701, thus achieving the locking of the protection door 2 and ensuring the safety during the sterilization process. When the sterilization is completed, the gas is discharged through the exhaust pipe 11. At this time, the spring 1204 rebounds to drive the connecting rod 1203 to slide, and the latch block 1205 is separated from the fixed block 13, and then the protection door 2 can be opened. When the protection door 2 is opened, the compression spring 706 rebounds to drive the fixed rod 707 and the first rack 702 to slide inside the sterilization frame 701. The sliding of the first rack 702 will cause the first gear 703 to rotate inside the sterilization frame 701, prompting the first gear 703 to drive the second gear 704 meshing with it to rotate. Further, the second gear 704 drives the second rack 705 to slide inside the sterilization frame 701. The sliding of the second rack 705 will synchronously drive the placement plate 8 inside the sterilization frame 701, so that the placement plate 8 drives the objects on its upper end to move forward, improving the working efficiency.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
