[0002] A laminar flow hood is an air purification device used to provide a local high-clean environment. Sterilized crystalline sulfanilamide refers to crystalline sulfonamide drugs that have undergone strict sterilization treatment. Sulfonamide drugs are a class of antibacterial drugs mainly used to treat infectious diseases caused by bacteria. When producing sterilized crystalline sulfanilamide, a laminar flow hood is required to purify the air flow in the environment to ensure the cleanliness of the production workshop.

[0036] Refer to Figure 1-6, A laminar flow hood that is convenient for cleaning, including a housing 1. An air intake frame 2 is fixedly connected to the left side of the housing 1. An air outlet hole 8 is provided on the right side of the housing 1. A fixing plate 3 is fixedly connected to the inner side of the housing 1. A blower 4 is arranged on the outer side of the fixing plate 3. A switching unit 7 is arranged on the upper side of the housing 1. A plurality of first filter frames 5 are arranged on the inner side of the housing 1. An electromagnetic plate 9 is fixedly connected to the rear side of the first filter frame 5. The first filter frame 5 is slidably connected to the housing 1. Both the housing 1 and the first filter frame 5 are made of metal materials, which is convenient for the electromagnetic plate 9 to connect the first filter frame 5 and the housing 1. When pulling out the first filter frame 5, the first filter frame 5 drives the electromagnetic plate 9 to move. When the first filter frame 5 is separated, the electromagnetic plate 9 seals the sliding holes on the first filter frame 5, facilitating the switching unit 7 to filter the air flow.

[0037] The switching unit 7 includes a fixed frame 701. The fixed frame 701 is fixedly connected to the upper side of the housing 1. A plurality of extraction holes 705 are provided on the upper side of the housing 1. A plurality of rectangular holes 702 are provided on the front side of the housing 1. A sealing plate 706 is arranged on the lower side of the housing 1. A fixing block 707 is fixedly connected to the upper side of the sealing plate 706. A pulling slot 708 is provided on the upper side of the fixing block 707. A first stabilizing block 709 is arranged on the inner side of the pulling slot 708. A second filter frame 710 is fixedly connected to the upper side of the first stabilizing block 709. A second stabilizing block 711 is fixedly connected to the upper side of the second filter frame 710. A U-shaped block 712 is arranged on the outer side of the second stabilizing block 711. A top plate 703 is fixedly connected to the upper sides of multiple U-shaped blocks 712. An electric push rod 704 is fixedly connected between the top plate 703 and the housing 1. A rectangular slot 713 is provided on the front side of the second filter frame 710. A second pull handle 714 is fixedly connected to the inner side of the rectangular slot 713. The sealing plate 706 is made of rubber material. When it is necessary to replace the first filter frame 5, control the electric push rod 704 to drive the top plate 703 to descend.

[0041] A first pull handle 6 is fixedly connected to the front side of the first filter frame 5, facilitating the pulling of the second filter frame 710 to move.

[0042] Working principle: During use, the fan 4 is started, and the airflow is filtered through the first filter frame 5. When it is necessary to disassemble the first filter frame 5, the electric push rod 704 is controlled to drive the second filter frame 710 to move to the inside of the housing 1, and then the first filter frame 5 is directly pulled, facilitating the continuous filtration of the airflow by the second filter frame 710. When it is necessary to disassemble the second filter frame 710, first control the electric push rod 704 to drive the second filter frame 710 upward, and through the first stabilizing block 709, the second stabilizing block 711, the extraction groove 708 and the U-shaped block 712, it is convenient to directly pull out the second filter frame 710, and the operation is simple.
