[0001] This utility model relates to the field of air purification technology, and in particular to a detachable return air plate transfer window. Background Technology

[0002] Pass-through windows are auxiliary air purification devices used in conjunction with cleanrooms and assembly cleanrooms. They provide local air purification for a sterile and clean working environment and are mainly suitable for transferring items between cleanrooms or between cleanrooms and non-cleanrooms.

[0003] Traditional pass-through windows have a one-piece molded inner cavity. When operators clean the return air panel, the disassembly time is long, which affects the operating efficiency of the equipment. After the pass-through window has been running for a period of time, dirt will enter the return air panel inside the cavity, which operators cannot clean, posing a potential risk to the cleaning effect and reducing the service life of the HEPA filter. At the same time, there are gaps around the return air panel, and external dust will enter into the gaps, which will also increase the disassembly time for operators. If the time is too long, dust will enter the box and reduce the cleaning effect. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the cleanliness of the pass-through window decreases after a period of use in the prior art, which leads to a reduction in the service life of the high-efficiency filter. Therefore, this invention proposes a detachable return air plate pass-through window.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A detachable return air transfer window includes a return air mesh plate installed on the side wall of a work box. The side wall of the work box is provided with multiple limiting blocks that limit the movement of the return air mesh plate. The work box has multiple movable cavities, each containing a reset assembly. The work box also contains multiple arc-shaped plates, and the reset assembly is connected to the arc-shaped plates.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-8 A detachable return air transfer window includes a work box 1, a tempered glass panel 5 which is hinged to rotate and set on the inner side wall of the work box 1, the tempered glass panel 5 is made of double-layer hollow tempered glass, and a stainless steel handle 6 is fixed to the outer side wall of the tempered glass panel 5 by bolt assembly. The outer side wall of the work box 1 is also provided with a buckle for limiting the stainless steel handle 6, so that the operator can open and close the tempered glass panel 5 and observe the operation inside the work box 1 through the tempered glass panel 5.

[0018] The control panel 4 is fixedly mounted on the side wall of the working chamber 1 by bolt assembly. The PAO detection port 2 is fixedly mounted on the side wall of the working chamber 1 by bolt assembly and is connected to the working chamber 1. The differential pressure gauge 3 is fixedly mounted on the side wall of the working chamber 1 by bolt assembly, so that the operator can easily observe the operation of the working chamber 1 through the differential pressure gauge 3. The control panel 4 is equipped with a control program, which controls the switching on and off of the centrifugal fan 7, the high-efficiency filter 8 and the sterilization lamp 9. This control program is existing technology and will not be described in detail here.

[0019] Centrifugal fan 7 is fixedly mounted on the inner wall of working chamber 1 by bolt assembly. HEPA filter 8 is fixedly mounted on the inner wall of working chamber 1 by bolt assembly. Sterilization lamp 9 is fixedly mounted on the inner wall of working chamber 1 by bolt assembly. Inner liner 11 is fixedly mounted on the inner wall of working chamber 1 by bolt assembly. The clean room is purified by centrifugal fan 7, HEPA filter 8 and sterilization lamp 9. Centrifugal fan 7 and HEPA filter 8 are each equipped with a driver program, which is connected to the control program, so that the operator can operate through the operation panel 4. The driver program is existing technology and will not be described in detail here.

[0020] The return air mesh plate 10 is installed on the side wall of the working box 1. Multiple rotating grooves are symmetrically opened on the side wall of the return air mesh plate 10. The rotating ring 21 is coaxially rotated in the rotating groove through the rotating assembly. The rotating ring 21 has a limit groove 22. The limit groove 22 is adapted to the limit block 16. The rotating ring 21 rotates in the rotating groove. This setting provides support for the return air mesh plate 10.

[0021] The side wall of the working box 1 is provided with multiple limiting blocks 16 for limiting the return air mesh plate 10. Multiple sliding holes are opened on the outer side wall of the working box 1. The rotating rod 15 is coaxially arranged in the sliding hole. The end of the sliding hole is provided with a groove that matches the limiting block 16. This arrangement prevents the limiting block 16 from being pulled out of the sliding hole when the rotating rod 15 slides, thus preventing the limiting function of the return air mesh plate 10 from being lost.

[0022] The rotating rod 15 and the limiting block 16 are fixedly connected end to end by a clamping sleeve. The rotating rod 15 slides in the sliding hole. The operator uses the sliding hole to make the limiting block 16 at the end of the rotating rod 15 abut against the limiting groove 22. By rotating the rotating rod 15, the limiting block 16 is driven to rotate. The limiting block 16 drives the rotating ring 21 to rotate in the rotating groove. The limiting block 16 and the limiting groove 22 cooperate to limit the return air screen 10, which facilitates the operator to install and disassemble the return air screen 10. By disassembling and cleaning the return air screen 10, the high-efficiency filter 8 is prevented from running too much, which would reduce its service life.

[0023] The rotating handle 12 is fixedly connected to the other end of the rotating rod 15 via a clamping sleeve. A limit hole is provided on the rotating handle 12, and a sliding groove adapted to the limit rod 13 is provided on the outer wall of the working box 1. The limit rod 13 is coaxially provided in the limit hole. The limit rod 13 passes through the limit hole and abuts against the inner wall of the sliding groove of the working box 1. This arrangement allows the limit rod 13 to limit the rotation of the rotating handle 12, preventing the rotating handle 12 from rotating excessively, which would cause the return air mesh plate 10 to shake and affect the cleaning effect.

[0024] The working box 1 has multiple movable cavities, and a reset assembly is provided in each movable cavity. The working box 1 has multiple arc-shaped plates 14, and the reset assembly is connected to the arc-shaped plates 14. The reset assembly includes a fixed rod 17 and a spring 18. The fixed rod 17 is fixedly installed on the inner wall of the movable cavity by a bolt assembly. The spring 18 is coaxially sleeved on the outer wall of the fixed rod 17. One end of the spring 18 is fixedly installed on the inner wall of the movable cavity by a hook, and the other end is fixedly installed on the end of the sliding plate 19 by a hook. This configuration provides driving force to the arc-shaped plate 14.

[0025] The reset assembly also includes a sliding plate 19 and a connecting rod 20. The sliding plate 19 is slidably disposed coaxially at the center of the fixed rod 17 via the sliding assembly. The connecting rod 20 is fixedly disposed at the end of the sliding plate 19 via a bolt assembly, and the other end of the connecting rod 20 is fixedly connected to the end of the arc plate 14 via a bolt assembly. This configuration provides power transmission to the arc plate 14.

[0026] The return air mesh plate 10 has arc-shaped inclined surfaces on its four sides, and the arc-shaped plate 14 also has an arc-shaped inclined surface. When the return air mesh plate 10 needs to be pulled out, when the arc-shaped inclined surface of the arc-shaped plate 14 connects with the arc-shaped inclined surface of the return air mesh plate 10, the arc-shaped plate 14 drives the connecting rod 20 to move vertically, and the connecting rod 20 drives the sliding plate 19 to move vertically. The sliding plate 19 squeezes the spring 18, and the arc-shaped plate 14 carries away the dust on the side wall of the return air mesh plate 10, preventing the operator from disassembling the return air mesh plate 10 due to excessive dust in the gaps, which would reduce the cleaning effect.

[0027] The aforementioned bolt assembly, rotating assembly, sliding block assembly, and flipping assembly are all prior art. The bolt assembly includes a bolt and a threaded hole for threading two components together. The rotating assembly includes a rotating groove, an annular block, and an annular groove, with the annular groove formed on the inner wall of the rotating groove, and the annular block rotating within the annular groove. The sliding block assembly includes a slider and a sliding groove, with the slider sliding within the sliding groove. The flipping assembly includes a fixed block and a rotating shaft, with the rotating shaft rotating within the fixed block.

[0028] The functional principle of this utility model can be explained through the following operation methods: This solution addresses the problems existing in the disassembly process, and the specific solutions are as follows: The operator moves the rotating rod 15 to drive the limiting block 16 to move horizontally. The limiting block 16 abuts against the inner wall of the limiting groove 22. The operator rotates the handle 12 to drive the limiting block 16 and the rotating ring 21 to rotate in the rotating groove, so that the limiting block 16 can limit the return air mesh plate 10, making it convenient for the operator to disassemble and clean the return air mesh plate 10 and extend the service life of the high-efficiency filter 8. The limiting rod 13 passes through the limiting hole and rotates the handle 12 to abut against the inner side wall of the sliding groove in the working box 1, preventing the return air mesh plate 10 from shaking and causing a decrease in the cleaning effect in the working box 1. As dust enters the gap between the return air mesh plate 10 and the working box 1, when the return air mesh plate 10 is disassembled, by moving the return air mesh plate 10, the arc-shaped inclined surface of the return air mesh plate 10 contacts the arc plate 14, causing the arc plate 14 to move. The arc plate 14 drives the connecting rod 20 and the sliding plate 19 to move. The sliding plate 19 slides on the fixed rod 17 and squeezes the spring 18 to ensure that the arc plate 14 abuts against the side wall of the return air mesh plate 10, thus cleaning the dust on the side wall of the return air mesh plate 10.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
