[0002] Cleanrooms require an extremely clean air environment, with dust particles controlled to the micron level. Since a large number of semi-finished products are frequently transferred between workshops, air showers and pass-through windows are needed to improve cleanliness. However, existing air showers and pass-through windows, when used in conjunction with cleanrooms, generally have limited effectiveness and are found to generate noticeable noise during operation. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A low-noise air shower pass-through window includes a frame, a blower, a blower distribution plate, a processing table, a side channel, a connecting channel, a noise reduction plate, a mesh plate, a filter layer, a suction fan, and a suction channel. The processing table is set inside the frame. A blower is installed at the top of the processing table, and a blower distribution plate is installed at the bottom of the blower. The blower distribution plate has several connecting cavities, which are connected to the processing table and the side channel. A noise reduction plate is installed at the side of the side channel. A mesh plate is installed at the bottom of the processing table. A suction fan is installed below the mesh plate. A filter layer is installed between the suction fan and the mesh plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS <​​​Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] like Figures 1 to 4 As shown, this embodiment provides a low-noise air shower transfer window, including a frame 1, a blower 2, a blower distribution plate 3, a processing table 4, a side channel 5, a connecting channel 6, a noise reduction plate 7, a mesh plate 8, a filter layer 9, a suction fan 10, and a suction channel 11. The processing table 4 is set inside the frame 1. The blower 2 is installed at the top of the processing table 4, and the blower distribution plate 3 is installed at the bottom of the blower 2. The blower distribution plate 3 is provided with a plurality of connecting cavities 31, and the connecting cavities 31 are connected to the processing table 4 and the side channel 5. The noise reduction plate 7 is installed at the side of the side channel 5. The mesh plate 8 is installed at the bottom of the processing table 4. The suction fan 10 is installed below the mesh plate 8. The filter layer 9 is set between the suction fan 10 and the mesh plate 8. The side channel 5 is connected to the suction channel 11 through the connecting channel 6.

[0025] Furthermore, the filter layer 9 and the suction fan 10 are installed inside the suction channel 11.

[0026] Furthermore, the air rod 12 is installed at the bottom of the suction fan 10 for adjustment.

[0027] Furthermore, a limiting device 13 is installed on the side of the air intake channel 11, and the limiting device 13 is located between the filter layer 9 and the air intake fan 10.

[0028] Furthermore, the limiting device 13 includes a mounting plate 131, a spring 132, and a limiting plate 133. The mounting plate 131 is fixedly installed on the side of the air suction channel 11, and the two ends of the spring 132 are respectively connected to the mounting plate 131 and the limiting plate 133.

[0029] Furthermore, an integrated cavity 14 is provided at the bottom of the frame 1, and an exhaust pipe 141 is connected through the integrated cavity 14.

[0030] Furthermore, a support leg 15 is provided at the bottom of the frame 1, and the support leg 15 is threadedly connected to the frame 1.

[0031] Furthermore, several noise reduction cavities 71 arranged in a U-shape are provided on the noise reduction plate 7.
