Description

Technical Field

[0001] This application relates to the technical field of article transfer and disinfection, and in particular to a clean pulse disinfection transfer window. Background Technology

[0002] Cleanroom environments are crucial in many industries with extremely high cleanliness requirements, such as semiconductor manufacturing, biopharmaceuticals, and food processing. In these industries, product quality and production process stability are highly dependent on the cleanroom environment's quality. Material transfer within the cleanroom environment is a critical step, as the introduction of any external contaminants can severely impact product quality and even lead to production failure. With continuous technological advancements, the cleanliness requirements for cleanroom environments across industries are becoming increasingly stringent, making contamination control during material transfer a critical and urgent issue to address.

[0003] In traditional cleanroom material transfer processes, various technologies are employed to reduce the entry of external contaminants. Mechanically sealed transfer windows are a common method, relying primarily on physical isolation to prevent the intrusion of external contaminants through a sealed structure. Another frequently used method is ultraviolet (UV) disinfection transfer windows, which utilize the bactericidal effect of ultraviolet light to disinfect materials and the transfer space during the transfer process, killing any microorganisms present. To prevent the simultaneous opening of both ends of the transfer window, current methods mainly rely on mutual vigilance between personnel at both ends. They are required to remain alert while retrieving and delivering items, and to avoid opening both windows simultaneously, thereby reducing the contamination of the clean area from the non-clean area.

[0004] However, while UV disinfection transfer windows can kill most microorganisms, their disinfection effect is limited against certain UV-resistant pathogens. Furthermore, relying on mutual attention among personnel to prevent simultaneous opening of windows and doors is highly unreliable; operators can easily become negligent when retrieving or delivering items, leading to both windows and doors opening at the same time, thus increasing the possibility of contamination of the clean area. Therefore, further improvements are needed. Summary of the Invention

[0005] To address the above issues, this application provides a clean pulse disinfection transfer window.

[0006] This application provides a clean pulse disinfection transfer window, which adopts the following technical solution: A clean pulse disinfection transfer window includes a window body with an inner cavity. Two opposite surfaces of the window body are respectively provided with door panels for opening and closing. The door panels are rotatably connected to the window body. Pulse lamps are installed on the top and inner sidewalls of the inner cavity of the window body. A controller electrically connected to the pulse lamps is installed on the window body to control the pulse lamps to operate at a preset pulse frequency and flashing time. The pulse lamps are pulse xenon lamps. The two door panels are designated as a first door and a second door. A limiting mechanism is provided inside the window body. The limiting mechanism includes a first connecting strip hinged to the first door, a second connecting strip hinged to the second door, a first limiting strip connected to the pivot of the first door, and a second limiting strip connected to the pivot of the second door. The window body has a first sliding groove for the first and second connecting strips to slide. The first connecting strip has a first engaging portion that cooperates with the second limiting strip, and the second connecting strip has a second engaging portion that cooperates with the first limiting strip. When the first door is opened, the first limiting strip engages with the second engaging portion to restrict the movement of the second connecting strip.

[0007] By adopting the above technical solution, pulsed xenon lamps are installed on the top and inner walls of the cleanroom cavity. Pulsed xenon light disinfection is highly efficient, effectively killing 99.9% of microorganisms, including UV-resistant pathogens, thus better meeting the disinfection needs of cleanrooms for material transfer. Simultaneously, a limiting mechanism is installed. When the first window is opened, the first limiting strip engages with the second locking part of the second connecting strip, restricting the movement of the second connecting strip. This reduces the simultaneous opening of both windows when retrieving or delivering items, minimizing contamination of the clean area from the non-clean area and improving the safety and reliability of the transfer window.

[0008] Preferably, the extension directions of the first and second limiting strips are adapted to the rotation trajectory of the corresponding window or door.

[0009] By adopting the above technical solution, the extension directions of the first and second limiting strips are set to match the rotation trajectory of the corresponding windows and doors, so that when the windows and doors are opened, the limiting strips can more accurately engage with the locking parts. Specifically, during the opening of the first window and door, the first limiting strip can accurately engage with the second locking part of the second connecting strip along its rotation trajectory, thereby effectively restricting the movement of the second connecting strip and thus restricting the opening of the second window and door; similarly, when the second window and door are opened, the second limiting strip can also accurately engage with the first locking part of the first connecting strip, restricting the opening of the first window and door. This better ensures that the two windows and doors will not open simultaneously when retrieving or delivering items, reducing the possibility of contamination of the clean area.

[0010] Preferably, a clean room and an outer room are located on both sides of the window, with the first window positioned closer to the outer room and the second window positioned closer to the clean room. The second connecting strip includes a fixed section and a sliding section, with the fixed section hinged to the second window. The limiting mechanism also includes a control component for controlling the connection between the sliding section and the fixed section.

[0011] By adopting the above technical solution, in the application scenario of the clean pulse disinfection transfer window, the two sides of the window are the clean room and the outer room, respectively. The first window door is closer to the outer room, and the second window door is closer to the clean room. The second connecting strip is divided into a fixed section and a sliding section, and the fixed section is hinged to the second window door. A control component is provided to control the connection between the two.

[0012] Preferably, the control component includes a connecting block, a first spring and a control element respectively connected to both ends of the connecting block, and a second spring connected to the bottom of the window. The first slide groove has a second slide groove for the connecting block to slide and connect. The connecting block is used to connect the fixed section and the sliding section. The first spring forces the connecting block to move towards the top of the first slide groove. A tray is provided inside the window. The other end of the second spring is connected to the tray, and the other end of the control element is connected to the tray.

[0013] By adopting the above technical solution, the connecting block in the control component can slide in the second slide within the first slide. Under the action of the first spring, the connecting block will move towards the top of the first slide. When an item is placed on the tray inside the window, the weight of the item causes the tray to press against the second spring, causing the tray to descend and pull the control component connected to the tray, thereby driving the connecting block to move downward. Since the connecting block is used to connect the fixed section and the sliding section, the connection between the fixed section and the sliding section can be achieved during the downward movement of the connecting block. Thus, when there are items on the tray, it can be used in conjunction with the limiting mechanism to ensure that only one window can be opened at a time, reducing the possibility of both windows being opened simultaneously and reducing the possibility of contamination of the clean area.

[0014] Only after the items have been removed, the second window door must be closed first, the first window door opened, and there are no items on the tray. The second window door can only be opened after the first window door has been opened. This structure is suitable for cleaning after a power outage and is designed to reduce the possibility of accidental contact during cleaning.

[0015] Preferably, the opposite side walls of the connecting block are respectively provided with grooves or protrusions along the height direction, the fixed section and the sliding section are respectively provided with protrusions or grooves near the side walls of the connecting block, and the surface of the connecting block near the sliding section is provided with a guide surface.

[0016] By adopting the above technical solution, the grooves 556 or protrusions 555 that penetrate the side walls of the connecting block along the height direction can cooperate with the corresponding protrusions 555 or through grooves 556 on the side walls of the fixed section 522 and the sliding section 523 near the connecting block 551. When items are placed on the tray, causing the tray to descend and pulling the control component to move the connecting block downwards, this cooperation connects the fixed section and the sliding section. At the same time, the guide surface of the connecting block near the surface of the sliding section can drive the second free end to slide along the first slide groove during the downward movement of the connecting block, so that the slot originally set on the sliding section reaches the appropriate position, so that the subsequent limit rod can be engaged. This ensures that only one window can be opened when there are items on the tray, further reducing the possibility of contamination of the clean area.

[0017] Preferably, the control component further includes a connecting rope disposed between the fixed section and the sliding section, the length of the connecting rope being longer than the length of the connecting block, the lower surface of the connecting block abutting against the connecting rope, and the distance between the two ends of the connecting rope shortening as the connecting block moves downward.

[0018] By adopting the above technical solution and incorporating a connecting rope, compared to the connection method of protrusions and grooves, the connecting rope has better flexibility and adaptability, which can reduce problems such as jamming and wear that may occur due to the cooperation of protrusions and grooves, making the connection between the fixed section and the sliding section smoother. In addition, the length of the connecting rope is longer than the length of the connecting block, which can ensure that the distance between the two ends of the connecting rope can be effectively shortened when the connecting block moves down, so as to achieve stable control of the limit state of the second window door, reduce the probability of failure, and improve the reliability and stability of the pass-through window.

[0019] Preferably, the lower surface of the connecting block is provided with an arc-shaped surface.

[0020] By adopting the above technical solution, compared with a normal flat surface, the curved surface can contact the connecting rope in a smoother way, reducing friction and jamming between the two, making the movement of the connecting rope more stable and efficient, thus more reliably realizing the connection and separation of the fixed section and the sliding section, further ensuring the function of only opening the window when there are items on the pallet, and improving the stability and reliability of the pass-through window.

[0021] Preferably, the first limiting strip includes a sleeve, a sliding rod slidably inserted into the sleeve, and a third spring built into the sleeve, wherein the third spring forces the sliding rod to move toward the first slot.

[0022] By adopting the above technical solution, in the clean pulse disinfection transfer window, the first limiting strip uses a structure of a sleeve, a sliding rod, and a third spring. The third spring continuously applies force to the sliding rod, forcing it to move closer to the first slot. When the first window is opened, this structure ensures that the sliding rod is more promptly and stably engaged in the first slot, thereby effectively limiting the movement of the second connecting strip connected to the second window. This ensures that both windows will not be opened simultaneously when retrieving or delivering items, greatly reducing the possibility of contamination of the clean area and further improving the safety and reliability of the transfer window.

[0023] In summary, this application has the following beneficial effects: 1. The pulsed xenon lamp works with a preset pulse frequency and flashing time, which has high disinfection efficiency and can kill 99.9% of microorganisms, including UV-resistant pathogens, thus reducing the problem of limited effectiveness of traditional UV disinfection against UV-resistant pathogens; 2. The limiting mechanism can prevent two windows from opening simultaneously, reducing the likelihood of both windows opening at the same time when retrieving or delivering items. This lowers the possibility of contamination in the clean area and solves the problem of simultaneous window opening due to human negligence. 3. The control components can control the windows and doors to open individually or in pairs depending on whether there are items on the tray, meeting the needs of different usage scenarios.

[0026] The following is in conjunction with the appendix Figure 1 - Appendix Figure 9 This application will be described in further detail below.

[0027] This application discloses a clean pulse disinfection transfer window.

[0028] Example 1: A clean pulse disinfection transfer window, as described above Figure 1 , Figure 2 The system includes a window 1 with an inner cavity 11. Opposite surfaces of the window 1 are provided with doorways 3 for opening and closing, allowing items to be placed inside. The doorways 3 are rotatably connected to the window 1 via pivots 14. The pivots 14 on both windows 1 are located on the same side, with the cleanroom and outer room located on opposite sides of the window 1, respectively. The two doorways 3 are designated as a first doorway 31 and a second doorway 32. The first window 1 is located closer to the outer room, and the second window 1 is located closer to the cleanroom. A latch 13 is provided on the window 1 to lock the free end of the doorway 3.

[0029] The top and inner wall of the inner cavity 11 of window 1 are equipped with pulse lamps 4, specifically pulsed xenon lamps. Pulsed xenon lamps are characterized by high disinfection efficiency, capable of releasing high-intensity pulsed light in a short time to kill various microorganisms. The pulse lamps 4 are fixed to the inner wall of window 1 by lamp holders, which are generally made of insulating and high-temperature resistant materials to ensure the stable operation of the pulse lamps 4. Window 1 is equipped with a controller electrically connected to the pulse lamps 4, which is electrically connected to a host computer to control the pulse lamps 4 to operate at a preset pulse frequency and flashing time.

[0030] Reference Figure 3A limiting mechanism 5 is provided inside the window 1 to control the opening and closing of the first window 1 and the second window 1. In this embodiment, the limiting mechanism 5 specifically includes a first connecting strip 51 hinged to the first window 31, a second connecting strip 52 hinged to the second window 32, a first limiting strip 53 connected to the pivot 14 of the first window 31, and a second limiting strip 54 connected to the pivot 14 of the second window 32. The first connecting strip 51 and the second connecting strip 52 are arranged to avoid the pivot 14. The window 1 is provided with a first sliding groove 15 for the first connecting strip 51 and the second connecting strip 52 to slide. The first connecting strip 51 is provided with a first locking part 511 that cooperates with the second limiting strip 54, and the second connecting strip 52 is provided with a second locking part 521 that cooperates with the first limiting strip 53.

[0031] In this embodiment, the extension directions of the first limiting strip 53 and the second limiting strip 54 are adapted to the rotation trajectory of the corresponding window 3. Specifically, the first locking part 511 is a first slot provided on the first connecting strip 51, and the second locking part 521 is a second slot provided on the second connecting strip 52. When the first window 31 is opened, the first limiting strip 53 and the second locking part 521 engage to restrict the movement of the second connecting strip 52.

[0032] The implementation principle of a clean pulse disinfection transfer window in this application embodiment is as follows: During the material transfer process in the cleanroom, the material is placed inside the window 1. The controller controls the pulse lamp 4 to operate at a preset pulse frequency and flashing time, effectively disinfecting the material and the transfer space. When the window 3 is opened, due to the action of the limiting mechanism 5, when the first window 31 is opened, the first limiting strip 53 engages with the second locking part 521 of the second connecting strip 52, restricting the movement of the second connecting strip 52. This reduces the simultaneous opening of both windows 3 when retrieving and delivering items, reduces contamination of the clean area from the non-clean area, and improves the safety and reliability of the transfer window.

[0033] This design improves the safety and reliability of material transfer in cleanrooms, representing a significant improvement over traditional pass-through window technology.

[0034] Example 2: Reference Figure 4 , Figure 5 The difference from Embodiment 1 is that in this embodiment, the second connecting strip 52 includes a fixed section 522 and a sliding section 523. The fixed section 522 is hinged to the second window 32. The limiting mechanism 5 also includes a control component 55 for controlling the sliding section 523 and the fixed section 522 to connect.

[0035] The control component 55 includes a connecting block 551, a first spring 552, a control element 553, and a second spring 554. The first slide groove 15 has a second slide groove 16 for the connecting block 551 to slide and connect. The connecting block 551 is used to connect the fixed section 522 and the sliding section 523. The connection between the connecting block 551, the fixed section 522, and the second sliding block is as shown in the figure. The opposite side walls of the connecting block 551 are respectively provided with grooves 556 or protrusions 555 along the height direction. The fixed section 522 and the sliding section 523 are respectively provided with protrusions 555 or grooves 556 on the side walls near the connecting block 551.

[0036] Reference Figure 5 , Figure 6 The first spring 552 is disposed in the second slide groove 16. One end of the first spring 552 is fixedly connected to the inner top wall of the second slide groove 16, and the other end of the first spring 552 is fixedly connected to the connecting block 551. The first spring 552 forces the connecting block 551 to move towards the top of the first slide groove 15.

[0037] Reference Figure 6 , Figure 7 In this embodiment, the control component 553 is a U-shaped rod. The upper end of the U-shaped rod is connected to the side wall of the connecting block 551, and the lower end of the U-shaped rod passes through the side wall of the window 1 and the tray 2. A third sliding groove 17 is provided in the window 1 for the U-shaped rod to slide and connect. One end of the control component 553 is connected to the lower surface of the connecting block 551, and the other end of the control component 553 passes through the window 1 to connect with the tray 2. The control component 553 includes a first connecting section connected to the connecting block 551 and a second connecting section connected to the tray 2 in sequence in the direction away from the connecting block 551. A through groove 18 is provided in the window 1 for the control component 553 to slide through. One end of the second spring 554 is connected to the tray 2, and the other end of the second spring 554 is connected to the bottom of the window 1.

[0038] Reference Figure 8 Since the sliding segment 523 will slide along the first sliding groove 15, in this embodiment, the first limiting bar 53 specifically includes a sleeve 531, a sliding rod 532 slidably inserted into the sleeve 531, and a third spring 533 built into the sleeve 531. The third spring 533 forces the sliding rod 532 to move toward the direction closer to the first slot.

[0039] When there are items on the tray 2, the tray 2 descends, pulling the control element 553, causing the connecting block 551 to move downwards. The grooves 556 or protrusions 555 that penetrate the side walls of the connecting block 551 along the height direction can cooperate with the corresponding protrusions 555 or through grooves 556 on the side walls of the fixed section 522 and the sliding section 523 near the side walls of the connecting block 551. This connects the sliding section 523 and the fixed section 522, while the slide rod 532 in the second limiting strip 54 is engaged in the second slot, allowing only one window 3 to be opened at a time. When there are no items on the tray 2, the second spring 554 pushes the tray 2 upwards, the control element 553 relaxes, and the connecting block 551 moves upwards under the action of the first spring 552. The sliding section 523 and the fixed section 522 separate. At this time, the second window 1 can be opened after the first window 1 is opened, allowing both windows 3 to be opened for special operations. This design increases the flexibility of the pass-through window and meets the needs of different situations.

[0040] Example 3: Reference Figure 9 The difference from Embodiment 2 is that the control component 55 also includes a connecting rope 558 disposed between the fixed section 522 and the sliding section 523. The length of the connecting rope 558 is longer than the length of the connecting block 551. The lower surface of the connecting block 551 abuts against the connecting rope 558. As the connecting block 551 moves down, the distance between the two ends of the connecting rope 558 is shortened. An arc-shaped groove 6 is provided on the lower surface of the connecting block 551 for the connecting rope 558 to abut against.

[0041] When the connecting block 551 moves downward, its arc-shaped surface contacts and applies pressure to the connecting rope 558, shortening the distance between the two ends of the connecting rope 558 and further enhancing the connection stability between the sliding section 523 and the fixed section 522. This makes the limiting mechanism 5 more reliable in restricting the window 3 when there are items on the tray 2, further reducing the possibility of both windows 3 opening at the same time and improving the safety of the cleanroom.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
