[0032] like Figures 1-6 As shown, this utility model discloses a multifunctional self-cleaning transfer window for laboratories, including a cabinet 1. The cabinet 1 is installed on the wall 2 between two adjacent laboratories and extends through the wall 2. The two side walls of the cabinet 1 inside the laboratory are the first side walls, and the two side walls connecting the cabinet 1 to the wall 2 are the second side walls. The first side walls have openings, and each opening has a cabinet door 3.
[0033] The cabinet 1 is provided with partitions 4 at intervals between the interior and the two second side walls. A first air duct 5 is formed between the partitions 4 and the second side walls. A storage cavity 6 is formed between the two partitions 4. An air outlet 7 is provided on the partitions 4 to connect the storage cavity 6 and the first air duct 5.
[0034] An electrical box 8 is installed on the top of the cabinet 1. The electrical box 8 is arranged in two layers: a filter chamber 9 in the lower layer and a fan chamber 10 in the upper layer. The filter chamber 9 is connected to the storage chamber 6 of the cabinet 1 and contains a filter assembly. A drive fan 12 is installed in the fan chamber 10 and its air inlet is connected to the filter chamber 9. A second air duct 13 is provided on the side wall of the electrical box 8. The fan chamber 10 is connected to the first air duct 5 in the cabinet 1 through the second air duct 13. The air outlet of the drive fan 12 faces the second air duct 13.
[0035] The cabinet 1 mentioned above can be directly embedded and fixed to the wall 2 of the laboratory. Alternatively, mounting holes adapted to the pass-through window can be pre-drilled on the laboratory wall 2, and then the pass-through window can be installed in the mounting holes and fixed.
[0036] The installation of cabinet 1 should be symmetrical on both sides to ensure its stability. Two side walls of cabinet 1 are fixed to wall 2, and the other two opposite side walls are placed in two laboratories respectively. The side wall placed in the laboratory is the first side wall, which serves as the opening side of cabinet door 3. The opening is made on the first side wall and cabinet door 3 is installed. The side wall connected to wall 2 is the second side wall. The second side wall serves as the air circulation channel inside cabinet 1. Specifically, two partitions 4 are set inside cabinet 1. The two partitions 4 are symmetrically set inside cabinet 1, and a certain gap is set between partitions 4 and the second side wall. A first air duct 5 is formed between partitions 4 and the second side wall. A grille-shaped air outlet is opened on the lower side of partition 4. The air outlet connects the first air duct 5 and the storage cavity 6 between the two partitions 4.
[0037] Above the cabinet 1 is the electrical box 8, which is integrated with the cabinet 1. The electrical box 8 has an internal layered structure. The lower layer is the filter chamber 9, which is connected to the storage chamber 6. The filter chamber contains filter components. The upper layer is the fan chamber 10, which contains two drive fans 12. The fan chamber 10 and the filter chamber 9 are connected by a fan channel. The air inlet of the drive fan 12 is located in the fan channel. A second air duct 13 is opened on the two side walls of the electrical box 8 corresponding to the first air duct 5. The second air duct 13 is connected to the first air duct 5 and the fan chamber 10. The air outlet of the drive fan 12 faces one side of the second air duct 13. The air outlets of the two drive fans 12 are in opposite directions and each corresponds to one second air duct 13.
[0038] The driving fan 12 causes the gas to flow in the cabinet 1 in the following direction: the gas enters the filter chamber 9 from the storage chamber 6, passes through the filter components in the filter chamber 9 and the driving fan 12, enters the fan chamber 10, then enters the second air ducts 13 on both sides of the fan chamber 10, enters the first air duct 5 along the second air duct 13, and finally enters the storage chamber 6 again from the air outlet 7. The gas passes through the filter components to filter the volatile solution gas and maintain the air environment in the storage chamber 6.
[0039] In a further embodiment, the filtration assembly includes an activated carbon adsorption block 11, which is disposed in the filtration chamber 9, and the storage chamber 6 and the filtration chamber 9 are connected through the activated carbon adsorption block 11.
[0040] The activated carbon adsorption block 11 is placed inside the filter chamber 9 and completely separates the upper and lower parts of the filter chamber 9, so that the gas in the filter chamber 9 must pass through the activated carbon adsorption module before it can enter the upper fan chamber 10 for circulation.
[0041] The activated carbon adsorption block 11 and the electrical box 8 can be detachably connected, allowing the activated carbon adsorption block 11 to be replaced periodically. The specific connection method can be a snap-fit, with inwardly recessed slots opened on two side walls of the electrical box 8. The two sides of the activated carbon adsorption block 11 slide into the slots, and the upper and lower limits are set. The specific structure will not be described in detail here.
[0042] In a further embodiment, the cabinet 1, electrical box 8, partition 4, and cabinet door 3 are all made of corrosion-resistant materials; the cabinet 1, electrical box 8, and cabinet door 3 are all made of 304 stainless steel; and the partition 4 is made of polypropylene.
[0043] By incorporating corrosion-resistant materials into the structure of each part of the transfer window, it is possible to prevent the transfer window from being exposed to volatile solution gases, thereby extending its service life.
[0044] In some other embodiments, the electrical box 8 is positioned on both sides of the two laboratories and is equipped with control components.
[0045] The control components include a control motherboard, a control switch 14, and an access control switch 15. The cabinet door 3 is connected to the cabinet body 1 via an electronic lock. The control switch 14, the access control switch 15, the electronic lock, and the drive fan 12 are all electrically connected to the control motherboard.
[0046] The aforementioned control board can be an existing PLC board, etc. The control switch 14 is used to control the fan's on / off state or the on / off state and speed, etc., and can be a push-button or rotary switch, etc. The access switch 15 is used to control the circuit's on / off state, and the access switch 15 can be a facial recognition, fingerprint recognition, or card reader, etc. The cabinet door 3 and the cabinet body 1 can be connected by a conventional surface lock or an electronic lock. The electronic lock needs to be equipped with a corresponding control switch 14.
[0047] It should be noted that the specific software control methods for controlling the opening and closing of the drive fan 12 and cabinet door 3 through the permission switch 15 and control switch 14 can all be implemented using existing technologies, and will not be elaborated here.
[0048] The electrical box 8 is located on one side of one of the laboratories and has an inspection hole 16 connecting the filter chamber 9 and the fan chamber 10. An inspection door is detachably connected to the inspection hole 16.
[0049] The electrical box is located on one side of another laboratory and has a circuit cavity 18. The circuit cavity 18 is isolated from the filter cavity 9 and the fan cavity 10. The control main board and its connection lines with the control switch 14, the access switch 15, the electronic lock, and the drive fan 12 are located in the circuit cavity 18.
[0050] The above-mentioned inspection hole 16 is provided in two parts. One part corresponds to the position of the activated carbon adsorption block 11 and is used for inspection, disassembly and replacement of the activated carbon adsorption block 11. The other part corresponds to the position of the drive fan 12 and is used for inspection of the drive fan 12. A first inspection door 17 is provided to maintain the structure inside the inspection hole 16 and at the same time facilitate opening for inspection.
[0051] The circuit cavity 18 is used to integrate the circuits of various electrical appliances, and a second inspection door 19 is provided to protect the circuit and facilitate maintenance.
[0052] The above specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0053] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
[0054] The present invention has been described in a relatively specific and detailed manner above through general description and specific embodiments. It should be noted that, without departing from the concept of the present invention, various modifications and improvements can be made to these specific embodiments, all of which fall within the scope of protection of this application. Therefore, the scope of protection of this patent application should be determined by the appended claims.
