Description

Technical Field

[0001] This utility model relates to the field of pass-through window technology, specifically a pass-through window applied in cleanrooms. Background Technology

[0002] A pass-through window is a perforated structure used in cleanrooms and other similar environments to facilitate the transfer of small goods. At the same time, it prevents the air from circulating between the cleanroom and the outside environment, thus avoiding air pollution from the outside.

[0003] A search revealed a patent, CN218347254U, which discloses a cleanroom pass-through window. The window includes a window body with hinges fixedly installed on both sides. A door is rotatably connected to the outer wall of each hinge, and a lock is fixedly installed on the outer wall of the door. A sliding groove is formed on the outer wall of the door, and a slider is slidably connected to the inner wall of the door within the groove. A sliding door is fixedly connected to the outer wall of the slider. Support plates are fixedly connected to both sides of the window body, and a fixing strip is fixedly connected to the inner wall of the window body. A partition is movably engaged with the inner wall of the fixing strip. First sealing strips are fixedly connected to both sides of the window body, and a second sealing strip is fixedly connected to the side of the door closest to the window body. This application effectively reduces the chances of users forgetting to close or lock the window. The sliding switch design improves the speed of opening and closing, reduces the range of motion required to open the door, facilitates rapid opening and closing, and minimizes the risk of contamination inside the window.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] In the prior art, as described in the aforementioned comparative document, when using a pass-through window to transfer goods, the left (right) side door of the pass-through window is opened, the goods are placed inside the pass-through window, the left (right) side door is closed, the right (left) side door is opened, the goods inside the pass-through window are taken out, and the right (left) side door is closed. This process requires opening and closing the doors on both sides of the pass-through window multiple times. If a large number of goods need to be transferred, the efficiency is low. Therefore, there is an urgent need in the art to improve the pass-through window used in cleanrooms to overcome the shortcomings of the prior art. Utility Model Content

[0030] 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.

[0031] Example 1

[0032] Please see Figures 1-9 A pass-through window for cleanrooms includes an upper fixed plate 3 and a lower fixed plate 4, which are symmetrically circular and fixedly installed within a wall 2. Two symmetrical, arc-shaped sealing arc plates 5 are fixedly installed at the edge between the upper fixed plate 3 and the lower fixed plate 4. An upper rotating plate 6 and a lower rotating plate 7, adapted to and sealing the two sealing arc plates 5, are provided between the upper fixed plate 3 and the lower fixed plate 4. A rotating column 9 is provided between the upper rotating plate 6 and the lower rotating plate 7. Several sealing partitions 10, each sealed on one side by one of the sealing arc plates 5, are provided on the side of the rotating column 9. The upper part of the upper fixed plate 3 is provided with a mechanism for driving the rotating column 9 to rotate. The drive motor 11 is fixedly installed on the opposite sides of the two sealed arc plates 5, and the fixed frame 12 is connected to the inside of the sealed arc plate 5. The fixed frame 12 is equipped with a disinfection device 13 for disinfection. It also includes a main controller 1 fixedly installed on the wall 2 for controlling the whole. The lower part of the upper rotating plate 6 is equipped with several sensors 18 for monitoring. When the sensors 18 detect that there are goods on the upper part of the lower rotating plate 7 between the two sealed partitions 10, the drive motor 11 is automatically started by the main controller 1. The maximum distance between the two sealed partitions 10 is less than the maximum horizontal diameter of the sealed arc plate 5.

[0033] In this embodiment, the entire device is installed on the wall 2, and sealant or other sealing materials are used to seal the transfer window and the wall 2. When goods need to be transferred, they are placed between two sealed partitions 10. When the sensor 18 detects that there are goods on the lower rotating plate 7, and a pre-set time is set (e.g., if the goods have not been moved for 3 seconds), the sensor 18 transmits a signal to the main controller 1, indicating that the goods need to be transferred. Alternatively, the main controller 1 can directly interact with the control panel on the main controller 1, and the main controller 1 starts the drive motor 11. The output of the drive motor 11 drives the upper rotating plate 6, the lower rotating plate 7, and the rotating column 9 to rotate. When the goods rotate to the inner side of a sealed arc plate 5, the drive motor 11 stops, and at the same time, several disinfection devices 1 are activated by the main controller 1. 3. The disinfection device 13 includes ultraviolet germicidal lamps as in the prior art. At this time, the space between the two sealing partitions 10 and the sealing arc plate 5 is sealed. A transparent glass, such as quartz glass, is fixedly installed at the connection between the fixed frame 12 and the sealing arc plate 5. This will not affect the sterilization effect of the disinfection device 13 on the goods. The goods are sterilized by turning on the disinfection device 13. Then, the drive motor 11 drives the upper rotating plate 6, the lower rotating plate 7 and the rotating column 9 to rotate again, rotating the goods to the other side of the wall 2 and taking them out. It is worth noting that the number of the above-mentioned sealing partitions 10 is not limited. During this process, the operator does not need to close and open the door multiple times, which improves the efficiency of the transfer window when transferring goods. Moreover, when the transfer window is transferring goods, goods can be transferred simultaneously at both sides of the wall 2, which increases the practicality of the transfer window.
