Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transfer rooms, and more specifically, it relates to a VHP sterilization transfer room. Background Art
[0002] The VHP transfer room sterilizes all exposed surfaces inside the transfer room through an integrated vaporized hydrogen peroxide sterilization system. Hydrogen peroxide has stronger sporicidal ability in the gaseous state than in the liquid state at room temperature. By generating free hydroxyl groups, it attacks cell components (including lipids, proteins, and DNA), thereby meeting the requirements of complete sterilization.
[0003] Now the VHP transfer room is used more widely. However, when sterilizing and transferring some solid items, the bottom surface of the item fits against the inner bottom surface of the transfer room, resulting in a poor sterilization effect in this area of the bottom surface of the item. At the same time, the air outlet of the VHP transfer room is fixed. To ensure that the outer surface of the item can all meet the sterilization standard, the sterilization time needs to be extended, which affects the sterilization and transfer efficiency of the item.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model
[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a VHP sterilization transfer room.
[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A VHP sterilization transfer room includes a VHP transfer room and a transfer window embedded inside the VHP transfer room. An infrared emitter and an infrared receiver are respectively fixedly connected to the inner top surface and the inner bottom surface of the transfer window. A rotating wheel is rotatably connected to the inner bottom surface of the transfer window. The rotating wheel is connected to the infrared receiver through a control system. A receiving tray is provided on the top surface of the rotating wheel. A wavy driving groove is formed on the outer peripheral wall of the rotating wheel. A number of linkage structures for driving the receiving tray to move up and down are arranged on the inner bottom surface of the transfer window. One end of the linkage structure is slidably connected in the driving groove, and the other end of the linkage structure is connected to the receiving tray.
[0007] The utility model is further arranged as follows: The linkage structure includes a support rod and a sliding rod that are slidably connected. The support rod is fixedly connected to the inner bottom surface of the transfer window. A driving block that extends into and slides in the driving groove is fixedly connected to the outer peripheral wall of the sliding rod. The receiving tray is rotatably connected to the sliding rod.
[0008] The utility model is further arranged as follows: The linkage structures are symmetrically arranged on both sides of the receiving tray. A rotating groove is formed on the sliding rod. A rotating ring that is rotatably connected in the rotating groove is fixedly connected to the bottom surface of the receiving tray.
[0009] The present utility model is further configured as follows: A connecting ring is fixedly connected to the outer peripheral wall of the support rod. The sliding rod is slidably connected within the connecting ring, and the driving block is located below the connecting ring. The sliding paths of the two driving blocks are symmetrically arranged.
[0010] The present utility model is further configured as follows: A telescopic rod is fixedly connected to the top surface of the rotating wheel. One end of the telescopic rod away from the rotating wheel is fixedly connected to the bottom surface of the receiving tray.
[0011] The present utility model is further configured as follows: The receiving tray is formed by a circular-arc-shaped combination of a number of receiving rods in a circumferential array. The horizontal projection area between adjacent receiving rods is larger than the horizontal projection area of the receiving rods.
[0012] In summary, the present utility model has the following beneficial effects:
[0013] By using the cooperation of the infrared emitter and the infrared receiver, the automatic detection of the item to be transferred is realized. When the item is placed in place, the rotation of the rotating wheel is automatically triggered, further driving the receiving tray to perform vertical displacement and rotation. Moreover, the rotation groove on the sliding rod is connected to the rotating ring on the bottom surface of the receiving tray, and the setting of the telescopic rod ensures that the receiving tray can both slide and rotate within the transfer window. The receiving tray reduces the contact area between the item to be transferred and the inner bottom surface of the transfer window, enabling the sterilization gas to fully disperse below the item, while increasing the contact area between the sterilization gas and the item, thereby accelerating the sterilization speed.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The present utility model will be described in detail below with reference to the drawings and embodiments.
[0020] A VHP sterilization transfer chamber, asFigure 1 - Figure 2 As shown in the figure, it includes a VHP transfer chamber 1 and a transfer window 2 embedded inside the VHP transfer chamber 1. A sterilization gas generating device and other devices for assisting sterilization are provided inside the VHP transfer chamber 1. After the sterilization gas is generated, it is filled into the transfer window 2 through a pipeline to sterilize the items to be transferred inside the transfer window 2. A receiving tray 6 is provided inside the transfer window 2. The receiving tray 6 is formed by a circular-array combination of a number of receiving rods with an arc-shaped cross-section. The horizontal projection area between adjacent receiving rods is larger than the horizontal projection area of the receiving rods. The items to be transferred are placed in the receiving tray 6. The contact area between the items to be transferred and the inner bottom surface of the transfer window 2 is separated by the receiving tray 6, so that the sterilization gas can escape below the items to be transferred. At the same time, the gap between adjacent receiving rods is large, reducing the contact between the receiving tray 6 and the items to be transferred, thereby increasing the contact area between the sterilization gas and the items to be transferred and accelerating the sterilization efficiency. The disk-shaped receiving tray 6 can also better stabilize the irregular items to be transferred, making the use process of the transfer window 2 more practical.
[0021] As Figure 2 - Figure 3 shown in the figure, an infrared emitter 3 and an infrared receiver 4 are respectively fixedly connected to the inner top surface and the inner bottom surface of the transfer window 2. A rotating wheel 5 is rotatably connected to the inner bottom surface of the transfer window 2. The rotating wheel 5 is connected to the infrared receiver 4 through a control system. The infrared emitter 3 generates infrared rays. When the infrared receiver 4 receives a signal, the control system is in a stopped state. When the item to be transferred is placed on the receiving tray 6, the item to be transferred will block the infrared signal generated by the infrared emitter 3. When the infrared receiver 4 cannot receive the signal, it will transmit it to the control system, and the control system drives the rotating wheel 5 to rotate inside the transfer window 2.
[0022] As Figure 2 - Figure 3As shown in the figure, a wavy drive groove 7 is formed on the outer peripheral wall of the rotating wheel 5. A number of linkage structures for driving the receiving tray 6 to move up and down are arranged on the inner bottom surface of the transfer window 2. The linkage structures are symmetrically arranged on both sides of the receiving tray 6. One end of the linkage structure is slidably connected in the drive groove 7, and the other end of the linkage structure is connected to the receiving tray 6. The linkage structure includes a support rod 8 and a sliding rod 9 that are slidably connected. The support rod 8 is fixedly connected to the inner bottom surface of the transfer window 2. A drive block 10 that extends into and slides in the drive groove 7 is integrally formed on the outer peripheral wall of the sliding rod 9. The receiving tray 6 is rotatably connected to the sliding rod 9. After the rotating wheel 5 rotates, the drive groove 7 on its outer peripheral wall will also rotate accordingly. When the drive block 10 slides to the trough of the drive groove 7, the drive block 10 drives the receiving tray 6 to slide to a position close to the inner bottom surface of the transfer window 2 through the sliding rod 9. After the drive groove 7 rotates, the drive block 10 slides from the trough position of the drive groove 7 to the peak position. During this process, the drive block 10 drives the receiving tray 6 to slide upward, and the distance between the receiving tray 6 and the inner bottom surface of the transfer window 2 increases. During the displacement of the receiving tray 6, on the one hand, the connection area with the sterilization gas is increased, and on the other hand, the airflow around the receiving tray 6 will be stirred, making the sterilization effect of the sterilization gas better.
[0023] As Figure 2 - Figure 4 shown, a rotating groove is formed on the sliding rod 9. A rotating ring 11 that is rotatably connected in the rotating groove is fixedly connected to the bottom surface of the receiving tray 6. A connecting ring 12 is fixedly connected to the outer peripheral wall of the support rod 8. The sliding rod 9 is slidably connected in the connecting ring 12, and the drive block 10 is located below the connecting ring 12. The sliding paths of the two drive blocks 10 are symmetrically arranged. A telescopic rod 13 is fixedly connected to the top surface of the rotating wheel 5. The end of the telescopic rod 13 away from the rotating wheel 5 is fixedly connected to the bottom surface of the receiving tray 6. The receiving tray 6 is also connected to the rotating wheel 5 through the telescopic rod 13. When the rotating wheel 5 rotates, the rotating force is transmitted to the receiving tray 6 through the telescopic rod 13, and the receiving tray 6 rotates accordingly. The rotating ring 11 on the receiving tray 6 is connected to the rotating groove of the sliding rod 9. Therefore, the sliding rod 9 will not block the rotation of the receiving tray 6, and the telescopic rod 13 can also slide accordingly when the sliding rod 9 slides and lifts the receiving plate to displace, ensuring the normal sliding and rotation of the receiving tray 6 in the transfer window 2, so as to achieve the purpose of accelerating the sterilization speed.
[0024] Working principle: The item to be transferred is placed on the receiving tray 6 inside the transfer window 2. When the item to be transferred is properly placed, it will block the infrared signal generated by the infrared emitter 3. After the infrared receiver 4 fails to receive the signal, it transmits the signal to the control system. The control system then drives the rotating wheel 5 to start rotating inside the transfer window 2. The rotating wheel 5 drives the receiving tray 6 to rotate through the telescopic rod 13. The rotating ring 11 is also rotatably connected in the rotating groove. At the same time, when the rotating wheel 5 rotates, the wavy driving groove 7 on its outer peripheral wall will also rotate accordingly. The driving block 10 slides in the driving groove 7. As the driving block 10 slides from the wave crest to the wave trough and from the wave trough to the wave crest in the driving groove 7, it drives the sliding rod 9 to slide up and down inside the connecting ring 12. During this process, the receiving tray 6 will be displaced up and down, increasing the distance between the receiving tray 6 and the inner bottom surface of the transfer window 2. The telescopic rod 13 also adjusts its length along with the displacement of the receiving tray 6 to ensure the smooth progress of the whole process.
[0025] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
