Description

Technical Field

[0001] This utility model relates to the field of silicon core cutting technology, and in particular to an ethylene oxide sterilizer with layered components. Background Technology

[0002] Ethylene oxide autoclaves, as highly efficient sterilization equipment, play an important role in medical devices, food processing, and pharmaceuticals. Through the chemical action of ethylene oxide gas, they effectively kill bacteria, viruses, fungi, and other microorganisms, ensuring that items meet sterility requirements. While ethylene oxide autoclaves typically have internal spaces for placing items, their design for this purpose has certain limitations.

[0003] Most sterilizers only have simple racks inside, which are mostly one-piece structures and cannot be flexibly layered according to the size and quantity of items. When there are many items to be sterilized or they are of different shapes, they are often piled up haphazardly on the racks. This not only makes full use of the space inside the sterilization chamber, reducing the loading capacity of the sterilizer, but also hinders the flow of ethylene oxide gas inside the sterilization chamber. Due to poor gas circulation, sterilization dead zones can easily form between items, preventing some items from being evenly exposed to ethylene oxide gas. This affects the sterilization effect and makes it difficult to ensure that all items are thoroughly and effectively sterilized. In addition, most existing racks are fixedly installed inside the sterilization chamber, making them inconvenient to disassemble and clean. After long-term use, stains and microorganisms can easily remain on the racks, potentially contaminating subsequent sterilization processes. Utility Model Content

[0021] Reference Figure 1 , Figure 2 and Figure 3As shown, an ethylene oxide sterilizer with layered components includes a housing 1, a sterilization chamber 11 formed at the front end of the housing 1, and a supply system for supplying ethylene oxide to the sterilization chamber 11. A cover 2 is installed on the front end of the housing 1 to shield the sterilization chamber 11, and one side of the housing 1 is rotatably connected to the cover 2. A layered placement rack 3 is detachably installed in the sterilization chamber 11, and several sets of placement racks 4 are installed on the layered placement rack 3. The placement racks 4 are slidably connected to the layered placement rack 3, and locking components 6 are provided on the placement racks 4 to lock into the layered placement rack 3. By setting up the layered placement rack 3 and the slidable placement racks 4, items to be sterilized can be arranged in layers, improving the utilization rate of the space inside the sterilization chamber 11, making the items more neat and orderly, and facilitating management and retrieval. At the same time, the detachable layered placement rack 3 is convenient for replacement or cleaning according to different sterilization needs. The locking element 6 secures the shelf 4 to the tiered shelf 3, preventing it from sliding during sterilization and ensuring the stability of the items. Furthermore, the shelf 4's position on the tiered shelf 3 is adjustable, allowing for the placement of items of varying heights. Several sets of electric heating elements 5 are installed in the sterilization chamber 11, and these 5 sets are fixedly connected to the equipment housing 1. The electric heating elements 5 in the sterilization chamber 11 regulate the temperature. Ethylene oxide achieves better sterilization results under certain temperature conditions. By controlling the temperature of the sterilization chamber 11 within a suitable range using the electric heating elements 5, the sterilization efficiency and effectiveness of ethylene oxide are improved, ensuring that the items receive thorough and effective sterilization.

[0022] Reference Figure 3 and Figure 4 As shown, the tiered shelf 3 includes a back frame 31, a connecting plate 32, and a front frame 33. The connecting plate 32 is fixedly connected between the back frame 31 and the front frame 33. A longitudinal slide bar 321 for sliding the shelf 4 is also provided on the connecting plate 32. Both ends of the longitudinal slide bar 321 are fixed to the connecting plate 32. The tiered shelf 3 adopts a structural design of back frame 31, connecting plate 32, and front frame 33, which is structurally stable and easy to assemble. The longitudinal slide bar 321 provides a sliding track for the shelf 4, allowing it to slide smoothly on the tiered shelf 3, facilitating the retrieval and placement of items, and ensuring the stability of the shelf 4 during sliding. A positioning vertical plate 311 is vertically installed on the rear end face of the back frame 31. Both ends of the positioning vertical plate 311 are fixedly connected to the back frame 31, and a magnetic suction cup 312 is fixedly installed at the center of the positioning vertical plate 311. The positioning vertical plate 311 and magnetic suction cup 312 on the rear end face of the back frame 31 can easily fix the layered placement rack 3 in a specific position in the sterilization chamber 11. The adsorption effect of the magnetic suction cup 312 can ensure that the layered placement rack 3 will not be displaced during the sterilization process, thus improving the stability and convenience of the installation of the layered placement rack 3.

[0023] Reference Figure 3and Figure 4 As shown, the display rack 4 includes an outer frame 41 and a middle rack 42. The middle rack 42 is installed in the outer frame 41 and is fixedly connected to the outer frame 41. The display rack 4 adopts a structure of an outer frame 41 and a middle rack 42, with the middle rack 42 installed in the outer frame 41. This structural design increases the load-bearing capacity of the display rack 4 and also provides more space for items, allowing items to be more rationally distributed on the display rack 4. This facilitates the flow of ethylene oxide gas and improves the sterilization effect. Sleeves 43 that cooperate with longitudinal slide bars 321 are fixedly installed on the four corners of the outer frame 41. The outer ends of the sleeves 43 are provided with positioning shells 44 for the installation of locking components 6. The sleeves 43 on the corners of the outer frame 41 cooperate with the longitudinal slide bars 321, enabling the display rack 4 to be accurately installed on the layered display rack 3 and ensuring the smooth sliding of the display rack 4. The positioning shell 44 provides a fixed position for the installation of the locking element 6, enabling the locking element 6 to function stably and ensuring the locking effect between the placement rack 4 and the layered placement rack 3.

[0024] Reference Figure 5 and Figure 6 As shown, the locking component 6 includes a locking slide rod 61, a support spring 62, and a holding screw 63. The locking slide rod 61 passes through the housing 43 and is supported on the longitudinal slide rod 321. The holding screw 63 is threadedly connected to the positioning housing 44, and a holding plate 631 is rotatably mounted on the inner end of the holding screw 63. The support spring 62 is installed between the holding plate 631 and the locking slide rod 61. The locking slide rod 61 of the locking component 6 passes through the housing 43 and is supported on the longitudinal slide rod 321. Through the cooperation of the support spring 62 and the holding screw 63, pressure can be applied to the locking slide rod 61, making it press tightly against the longitudinal slide rod 321, thus achieving a secure lock between the placement rack 4 and the layered placement rack 3. The threaded connection of the holding screw 63 allows for easy adjustment of the locking force to adapt to different usage requirements.

[0025] In this embodiment, during the placement and sterilization process, the cap 2 is opened, and the items to be sterilized are placed on the rack 4. The number and position of the rack 4 are selected appropriately based on the size and quantity of the items. After the items are placed, the rack 4 is locked onto the layered rack 3 by rotating the clamping screw 63. The cap 2 is closed, and the supply system is started to supply ethylene oxide gas into the sterilization chamber 11. At the same time, the electric heating element group 5 is started to adjust the temperature inside the sterilization chamber 11 to a suitable temperature. This temperature is determined based on the sterilization characteristics of ethylene oxide and the properties of the items, ensuring that ethylene oxide achieves the best sterilization effect. During the sterilization process, the temperature and pressure inside the sterilization chamber 11 are kept stable for a certain period of time to ensure that the items are thoroughly sterilized. After sterilization, the supply system and the electric heating element group 5 are turned off, and the ethylene oxide gas inside the sterilization chamber 11 is allowed to escape. After the gas is released, the cap 2 is opened, the locking element 6 is released, and the rack 4 is slid off the layered rack 3 to remove the sterilized items.

[0026] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
