Description

Technical Field

[0001] This utility model relates to the field of cleanroom technology, and in particular to a portable cleanroom. Background Technology

[0002] With the rapid development of industries such as semiconductors, precision electronics, biomedicine, medical devices, and food processing, the cleanliness requirements for production and experimental environments are becoming increasingly stringent. The traditional solution is to build fixed cleanrooms, which not only require huge initial investments and long construction periods, but also cannot be moved once built, resulting in extremely poor flexibility. However, in actual production and R&D, not the entire workshop needs high cleanliness; perhaps only a specific piece of equipment or process requires it. During production line modifications, equipment maintenance, or short-term R&D projects, a temporary clean environment is needed. Existing fixed cleanroom technologies generally lack flexibility, are immobile, and cannot be moved according to changes in production layout, resulting in rigid applicability. Assembly is cumbersome, time-consuming, and labor-intensive, often involving numerous independent rods and screws for on-site assembly, much like assembling large furniture—a complex and inefficient process that demands skilled operators and is prone to affecting sealing and stability due to installation errors. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] See Figures 1 to 8 The portable cleanroom provided in this embodiment includes a cleanroom body 1 and a support frame 2 disposed inside the cleanroom body 1. The cleanroom body 1 is characterized by having a PVC anti-static curtain 11 on its outer side. The PVC anti-static curtain 11 includes a top surface 12 and side surfaces 13, with a fan filter unit 17 disposed on the top surface 12. The support frame 2 includes a support plate 21 and a folding support column 25, with the support plate 21 and the folding support column 25 movably connected. The support frame 2 is a skeletal structure that supports the cleanroom body 1 and can be folded and stored, facilitating installation and transport after folding.

[0030] The portable cleanroom provided by this utility model features several structural improvements. The improved support frame uses a movable support plate and folding support column, allowing the entire support skeleton to be folded and retracted for easy installation and reduced volume during transportation and storage. It is easy to carry to different work sites, such as laboratories, production line maintenance, and temporary operating rooms, making it suitable for scenarios requiring mobile and temporary clean environments. Users do not need to use complex tools or perform tedious assembly of components; they only need to unfold the folded support frame and cover it with a PVC anti-static curtain to quickly form a stable main structure. This shortens the setup and dismantling time of the cleanroom, lowers the barrier to entry, improves work efficiency, and achieves portability.

[0031] See Figures 3 to 4 In this embodiment, four folding support columns 25 are provided. The four folding support columns 25 can be easily unfolded and folded. During installation, the four folding support columns 25 are unfolded to a certain angle, and then covered with PVC antistatic curtains 11 to form the surrounding wall panels of the clean space. They have antistatic function and prevent dust adsorption. The fan filter unit 17 draws in external air, which is filtered by a high-efficiency filter and then sent into the shed vertically or horizontally to form a clean airflow.

[0032] See Figure 5 In this embodiment, eight folding support columns 25 are provided. These eight columns allow for easy unfolding and folding, offering more internal space and greater stability compared to four columns. Sealing gaskets 14 are provided at the bottom of each of the eight columns 25 for a removable seal at the connection point with the curtain, ensuring airtightness.

[0033] See Figures 6 to 8 In this embodiment, a movable crossbar 24 is provided between the support plate 21 and the folding support column 25, and the movable crossbar 24 is movably connected to the support plate 21 and the folding support column 25. A connecting groove 23 is provided on the support plate 21, and a support shaft 27 is provided within the connecting groove 23. A support column groove 26 is provided at the end of the folding support column 25 that connects to the movable crossbar 24, and a support shaft 27 is provided within the folding support column 25. In this embodiment, by providing the movable crossbar 24, the top of the cleanroom body 1 is relatively regular due to the support of the movable crossbar 24, thus expanding the top space and increasing stability.

[0034] See Figures 1 to 2In this embodiment, the fan filter unit 17 is mounted on a support plate 21, and the support plate 21 has a support plate through hole 22 that matches the air outlet of the fan filter unit 17. A purification lamp 15 is mounted on the top surface 12 of the curtain. The purification lamp 15 has a built-in ultraviolet lamp and LED lighting; it can provide both illumination and disinfection. Normally, it only provides illumination; when disinfection is required, the ultraviolet lamp is turned on. The purification lamp 15 is installed on the ceiling inside the cleanroom, and the movable crossbar 24 also provides support for the installation of the purification lamp 15.

[0035] See Figures 1 to 2 In this embodiment, a central support column 28 is provided at the bottom of the support plate 21, and the height of the central support column 28 is less than the height of the folding support column 25. A cleanroom interlocking door 16 is provided on the side of the curtain 13, and a PVC anti-static side curtain is provided inside the side of the curtain 13.

[0036] See Figures 1 to 2 In this embodiment, the cleanroom interlock door 16 is located at the entrance and exit on the door curtain. It adopts an interlock design to prevent direct communication between the internal and external airflows and maintain the internal cleanliness. The cleanroom interlock door 16 is equipped with a PVC anti-static side curtain for anti-static treatment during the manufacturing and maintenance of electronic components.

[0037] See Figures 1 to 2 In this embodiment, a control box 18 is provided, which is equipped with a PLC controller to centrally control the operation of the entire cleanroom, such as controlling the fan filter unit, speed adjustment, purification lamps, etc.

[0038] In this embodiment, the user removes the support frame 2 from its stored state and unfolds the originally folded skeleton into a stable three-dimensional frame by operating the movable connection points between the folding support column 25 and the movable crossbar 24. The central support column 28 provides additional central support at the bottom, enhancing the overall structural stability and load-bearing capacity. The top surface 12 of the PVC antistatic curtain is covered on the top frame, and the side surface 13 of the curtain is fixed to the surrounding frame. The bottom contacts the ground through the sealing gasket 14, forming a bottom-sealed tent structure to prevent unfiltered air from entering from the bottom. The cleanroom interlock door 16 is installed on the side of the curtain as a personnel entrance and exit. Its interlock function ensures that the two doors cannot be opened simultaneously, maintaining the internal air pressure and cleanliness. The fan filter unit 17 is activated, and the fan inside it starts working. The fan draws in ambient air from outside the cleanroom and forces it through the high-efficiency filter inside the unit. The filtered clean air passes through the support plate through-hole 22 and enters the sealed space enclosed by the PVC antistatic curtain. The clean air is delivered vertically downwards from the ceiling, forming a laminar or quasi-laminar airflow pattern. This airflow effectively pushes down and carries away particulate matter generated inside, including particles generated by personnel activities. As the fan continuously supplies air into the shed, it creates a slight positive pressure inside. This positive pressure causes clean air inside the shed to seep out through the gaps in the curtains, thus preventing unfiltered air from flowing back in. The sealing gasket 14 ensures an effective seal at the bottom during this process.

[0039] After the work is completed, reverse the above process: disconnect the power and disconnect the control box 18; remove the PVC anti-static curtain and fold it for storage; release the locks of each movable connection point, fold the support frame 2 along the support axis 27 and other hinge points, so that the folded support column 25 and movable crossbar 24 are gathered together, and finally folded into a compact volume for easy transportation and storage.

[0040] In summary, the above embodiments of this utility model, through various structural improvements, feature an improved support frame that uses a movable support plate and folding support columns. This allows the entire support skeleton to be folded and retracted, facilitating installation and reducing volume during transportation and storage. It is easily portable to different work sites, such as laboratories, production line maintenance, and temporary operating rooms, making it suitable for scenarios requiring mobile, temporary clean environments. Users do not need complex tools or tedious component assembly; simply unfold the folded support frame and cover it with a PVC anti-static curtain to quickly form a stable main structure. This shortens the setup and dismantling time of the cleanroom, lowers the barrier to entry, improves work efficiency, and achieves convenient installation. The improved support frame, when unfolded, provides a robust and reliable skeleton for the cleanroom body. Functional components such as the fan filter unit and PVC anti-static curtains are located on the top or sides of the curtain, ensuring the overall stability of the cleanroom during operation and preventing airflow and cleanliness issues caused by structural swaying. The integrated design ensures the equipment is ready to use out of the box and fully functional.

[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
