[0056] Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0057] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0058] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Furthermore, components, features, and elements with the same names in different embodiments of this application may have the same meaning or different meanings, the specific meaning of which must be determined by its interpretation in that specific embodiment or further in conjunction with the context of that specific embodiment.

[0059] It should be understood that although the terms first, second, third, etc., may be used in this document to describe various types of information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this document, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if," as used herein, can be interpreted as "when," "when," or "in response to determination." Furthermore, as used herein, the singular forms "a," "one," and "the" are intended to also include the plural forms unless the context indicates otherwise.

[0060] It should be further understood that the terms “comprising” or “including” indicate the presence of features, steps, operations, elements, components, items, kinds, and / or groups, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, kinds, and / or groups.

[0061] The terms “or,” “and / or,” and “including at least one of the following” as used in this application may be interpreted as inclusive, or mean any one or any combination thereof. For example, “including at least one of the following: A, B, C” means “any one of the following: A; B; C; A and B; A and C; B and C; A and B and C”, or “A, B or C” or “A, B and / or C” means “any one of the following: A; B; C; A and B; A and C; B and C; A and B and C”. Exceptions to this definition will only occur if the combination of elements, functions, steps, or operations is inherently mutually exclusive in some way.

[0062] Currently, biosafety cabinets can be divided into three main categories: Class I, Class II, and Class III, to meet different biological research requirements. Among them, Class II biosafety cabinets are the most widely used type. In some Class II biosafety cabinets, clean air is circulated and filtered after passing through the work area before being blown back into the work area; while in others, clean air is exhausted to the outside after passing through the work area.

[0063] After use, biosafety cabinets require sterilization, typically by covering the cabinet with a sealed cover or plastic bag and filling it with sterilizing gas. However, current biosafety cabinet sterilization methods require external devices, resulting in low efficiency and complex procedures, thus reducing user experience.

[0064] To address the aforementioned issues, this invention provides a biosafety system and its disinfection method. The system features two openable and closable ports on both the cabinet and the enclosure, with each port corresponding to the others and interconnected. This allows the disinfection gas to flow within a sealed environment, minimizing gas leakage. Furthermore, the entire structure is simple, reliable, and cost-effective, reducing unnecessary parts and resulting in better disinfection.

[0065] The preferred technical solution of the biosafety system and disinfection method of the present invention is described below with reference to the accompanying drawings.

[0066] Example 1

[0067] Figure 1 This is a first-view structural schematic diagram of the biosafety system provided in the embodiments of this application. Figure 2 This is a second-view structural schematic diagram of the biosafety system provided in the embodiments of this application. Figure 3 This is a schematic diagram of the structure of the biosafety cabinet provided in the embodiments of this application. Figure 4 This is a schematic diagram of the biosafety cabinet provided in the embodiments of this application.

[0068] like Figures 1 to 4As shown, this application embodiment provides a biosafety system 300, including a biosafety cabinet 100 and a disinfection cabinet 200. The biosafety cabinet 100 includes a housing 110 and a controller, and the disinfection cabinet 200 includes a cabinet 210. The cabinet 210 is configured to generate disinfection gas, and the housing 110 and the cabinet 210 are respectively provided with two openable and closable communication ports.

[0069] Understandably, the front opening of the enclosure 110 serves as the front window of the biosafety cabinet 100, through which operators work within the work area.

[0070] In some examples, the housing 110 may be made of metal, and its material may include one or more of copper, iron, aluminum, tin, and lead. The casting mold may be made of sand, metal, or ceramic.

[0071] In other examples, the housing 110 may be made of plastic. During injection molding, molten plastic is injected under pressure into a plastic product mold, and then cooled and solidified to obtain the desired plastic part.

[0072] It should be noted that the specific material of the housing 110 is not limited in this embodiment.

[0073] Of course, during manufacturing, the housing 110 can also be made of steel plate, plastic or synthetic materials, provided that the strength is guaranteed.

[0074] Accordingly, in some examples, the cabinet 210 may be a metal component, and its material may include one or more of copper, iron, aluminum, tin, and lead.

[0075] In other examples, cabinet 210 may be made of plastic.

[0076] It should be noted that the specific materials of the cabinet 210 are not subject to further restrictions in this embodiment.

[0077] Of course, during manufacturing, the cabinet 210 can also be made of steel plate, plastic or synthetic materials, provided that the strength is guaranteed.

[0078] It should be noted that the box 110 has two openable and closable connecting ports, and the cabinet 210 also has two openable and closable connecting ports.

[0079] Correspondingly, the connecting opening can be any shape, such as square, elliptical, trapezoidal, etc. This embodiment does not impose any specific restrictions on this.

[0080] The connecting ports of the box 110 and the cabinet 210 are set one-to-one and connected to each other so that the disinfection gas in the disinfection cabinet 200 can circulate in the cabinet 210 and the box 110.

[0081] In other words, the two connecting ports on the box 110 and the two connecting ports on the cabinet 210 are connected to each other, forming a closed loop.

[0082] This setup allows the disinfection gas inside the disinfection cabinet 200 to circulate back and forth within the cabinet 210 and the box 110, which can improve disinfection efficiency.

[0083] The controller is connected to each connection port and is configured to open the outdoor air outlet 115 and close each connection port when the pressure of the outdoor air outlet 115 of the biosafety cabinet 100 reaches a preset pressure value.

[0084] It should be noted that when the disinfection gas inside the disinfection cabinet 200 circulates back and forth within the cabinet body 210 and the box body 110, after a long period of time, a certain pressure will exist at the outdoor air outlet 115 of the biosafety cabinet 100. When the pressure at the outdoor air outlet 115 of the biosafety cabinet 100 reaches the preset pressure value, it means that the amount of disinfection gas injected into the box body 110 has reached the required amount for disinfection, which is reflected in the pressure at the outdoor air outlet 115 reaching the preset pressure value. At this point, it indicates that the disinfection of the biosafety cabinet 100 has reached the standard. Open the outdoor air outlet 115 and close all connecting ports to end the disinfection process.

[0085] In addition, it should be noted that the biosafety cabinet 100 provided in this application embodiment can be an A2 type biosafety cabinet 100, a B2 type biosafety cabinet 100, or an A2 exhaust type biosafety cabinet 100.

[0086] In addition, the biosafety cabinet 100 can be switched between three types. Specifically, the biosafety cabinet 100 provided in this application embodiment can be any of the above-mentioned types of biosafety cabinet 100, or a biosafety cabinet 100 in any mode.

[0087] With the above configuration, namely, the box 110 and the cabinet 210 are each provided with two openable and closable communication ports, and the communication ports of the box 110 and the cabinet 210 are connected to each other in a one-to-one correspondence, so that the disinfection gas can flow in a closed environment, reducing the outflow of disinfection gas. Moreover, the whole structure is simple and reliable, with low cost, reducing unnecessary parts, and better disinfection effect.

[0088] like Figures 1 to 4 As shown, in some optional embodiments, the two connecting ports of the housing 110 include a first air inlet 116 and a first air outlet 117, and the two connecting ports of the cabinet 210 include a second air inlet 211 and a second air outlet 212.

[0089] It should be noted that the first air inlet 116 and the first air outlet 117 are interconnected, and the second air inlet 211 and the second air outlet 212 are interconnected.

[0090] In some examples, the first air inlet 116 and the first air outlet 117 may have the same or different shapes; however, the specific embodiments of this application are not limited in detail here.

[0091] For example, the first air inlet 116 and the first air outlet 117 can be in any shape, such as square, elliptical, trapezoidal, etc. The embodiments of this application do not impose specific limitations on this.

[0092] Accordingly, in some examples, the second air inlet 211 and the second air outlet 212 may have the same or different shapes, and the specific embodiments of this application are not limited in detail here.

[0093] For example, the second air inlet 211 and the second air outlet 212 can be in any shape, such as square, elliptical, trapezoidal, etc. The embodiments of this application do not impose specific limitations on this.

[0094] The first air inlet 116 and the second air outlet 212 are connected to each other, and the first air outlet 117 and the second air inlet 211 are connected to each other, so that the disinfection gas in the disinfection cabinet 200 circulates in the cabinet 210 and the box 110.

[0095] It should be noted that the disinfection gas inside the cabinet 210 first flows out through the second air outlet 212, then flows into the cabinet 110 through the first air inlet 116, where it is disinfected. Finally, it flows back into the cabinet 210 through the first air outlet 117 of the cabinet 110 and the second air inlet 211 of the cabinet 210, and so on.

[0096] like Figures 1 to 4 As shown, in some optional embodiments, the housing 110 encloses a working area, and the working area is provided with a first air inlet 111, a second air inlet 112, an air outlet 113, an indoor air outlet 114, and an outdoor air outlet 115 that are interconnected. The first air inlet 111 and the second air inlet 112 are both connected to the indoor air, and the first air inlet 111, the second air inlet 112, the air outlet 113, the indoor air outlet 114, and the outdoor air outlet 115 are all openable and closable openings.

[0097] Understandably, the front opening of the enclosure 110 serves as the front window of the biosafety cabinet 100, through which operators work within the work area. The front window is the first air inlet 111, used to draw in air from the room. A second air inlet 112 is located on the top of the enclosure 110, also used to draw in air from the room. The design of the second air inlet 112 facilitates air replenishment to the biosafety cabinet 100.

[0098] The housing 110 has an air outlet 113 at the top of the working area for supplying gas to the culture dishes placed on the working platform within the working area.

[0099] The housing 110 has an indoor air outlet 114 and an outdoor air outlet 115 at the top of the working area. The indoor air outlet 114 is used to exhaust gas into the room, and the outdoor air outlet 115 is used to exhaust gas to the outside.

[0100] The controller is configured to close the first air inlet 111, the second air inlet 112, the indoor air outlet 114, and the outdoor air outlet 115 when the disinfection cabinet 200 is disinfecting.

[0101] It should be noted that when the biosafety cabinet 100 needs to be disinfected, the first air inlet 116, the second air outlet 212, the first air outlet 117, and the second air inlet 211 are connected, while the first air inlet 111, the second air inlet 112, the indoor air outlet 114, and the outdoor air outlet 115 are closed. This allows the disinfection gas entering the cabinet 110 to be disinfected in a closed environment, further improving the disinfection concentration and efficiency of the disinfection gas.

[0102] like Figures 1 to 4 As shown, in some optional embodiments, a first fan 120 is installed at the air supply outlet 113, a second fan 130 is installed at the indoor air outlet 114, and an outdoor exhaust fan 140 is installed at the outdoor air outlet 115.

[0103] In some examples, the first fan 120, the second fan 130, and the exhaust fan 140 can be connected to the housing 110 by either a detachable connection or a fixed connection.

[0104] For example, the two are connected by bolts, clips, or hanging. Specifically, the embodiments of this application are not limited in detail here.

[0105] The first air inlet 116 is connected to the air inlet of the first fan 120, and the first air outlet 117 is connected to the air outlet of the second fan 130.

[0106] It should be noted that the disinfection gas inside the cabinet 210 flows into the box 110 through the second air outlet 212, the first air inlet 116, and the air inlet of the first fan 120, where it is disinfected. Then it flows back into the cabinet 210 through the air outlet of the second fan 130, the first air outlet 117 of the box 110, and the second air inlet 211 of the cabinet 210, thus circulating in this way.

[0107] like Figures 1 to 4As shown, in some optional embodiments, the controller is communicatively connected to the first fan 120, the second fan 130 and the exhaust fan 140 respectively. The controller is configured to open the outdoor air outlet 115 and shut down the first fan 120 and the second fan 130 when the pressure at the outdoor air outlet 115 reaches a preset pressure value.

[0108] It should be noted that when the biosafety cabinet 100 needs to be disinfected, the first fan 120 and the second fan 130 provide power for the flow of disinfection gas.

[0109] Of course, when the disinfection of the biosafety cabinet 100 is finished, the outdoor air outlet 115 is opened, and the first fan 120 and the second fan 130 are turned off, that is, the first air inlet 116 and the first air outlet 117 are closed, thereby stopping the disinfection.

[0110] Continue to refer to Figures 1 to 4 In some alternative embodiments, the biosafety system 300 further includes a piping assembly 310, which includes a first piping 311 and a second piping 312.

[0111] The first pipe 311 is used to connect the first air inlet 116 and the second air outlet 212, and the second pipe 312 is used to connect the first air outlet 117 and the second air inlet 211.

[0112] Understandably, the design of the piping assembly 310 facilitates the connection between the biosafety cabinet 100 and the disinfection cabinet 200.

[0113] In some examples, one end of the first conduit 311 can be installed with a detachable or fixed connection to the first air inlet 116, for example, a bolt or snap-fit ​​connection.

[0114] Similarly, in some examples, the other end of the first pipe 311 and the second air outlet 212 can be installed using a detachable or fixed connection method, such as a bolt or snap-fit ​​connection.

[0115] This design allows for the installation and disassembly of the first pipeline 311 with the biosafety cabinet 100 and the disinfection cabinet 200, respectively, and enables its disassembly and maintenance in the future.

[0116] In some examples, one end of the second conduit 312 can be installed with a detachable or fixed connection to the first outlet 117, for example, by bolts or clips.

[0117] Similarly, in some examples, the other end of the second pipe 312 can be installed with a detachable or fixed connection to the second air inlet 211, for example, by bolts or clips.

[0118] This design allows for the installation and removal of the second pipeline 312, which can then be disassembled and maintained later.

[0119] It should be noted that the first pipe 311 and the second pipe 312 can be adjusted according to the actual situation.

[0120] In some alternative implementations, the biosafety system 300 also includes a sealing assembly comprising a first seal and a second seal.

[0121] The first sealing element is fitted onto the end of the first pipe 311 to seal the connection between the first pipe 311 and the first air inlet 116, and the second sealing element is fitted onto the end of the second pipe 312 to seal the connection between the second pipe 312 and the first air outlet 117.

[0122] Understandably, the design of the sealing components ensures that the enclosure 110 and the cabinet 210 are in a sealed state, thereby improving the sealing performance.

[0123] In some examples, the materials of the first and second seals can be nitrile rubber, acrylic rubber, etc., but this application embodiment does not specify a particular material.

[0124] Optionally, the first and second seals are made of rubber.

[0125] For example, the first seal and the second seal can be vulcanized rubber. Vulcanized rubber refers to unvulcanized rubber that has been vulcanized.

[0126] The biosafety system provided in this application includes a biosafety cabinet and a disinfection cabinet. The biosafety cabinet includes a housing and a controller. The disinfection cabinet includes a cabinet body, which is configured to generate disinfection gas. Both the housing and the cabinet body have two openable and closable communication ports. The communication ports of the housing and the cabinet body are arranged one-to-one and interconnected to allow the disinfection gas inside the disinfection cabinet to circulate within the cabinet and the housing body. The controller is communicatively connected to each communication port and is configured to open the outdoor air outlet and close each communication port when the pressure at the outdoor air outlet of the biosafety cabinet reaches a preset pressure value.

[0127] The enclosure and cabinet each have two openable and closable ports, and these ports are interconnected, allowing the disinfection gas to flow within a sealed environment, reducing gas leakage. The entire structure is simple, reliable, and low-cost, with fewer unnecessary parts, resulting in better disinfection.

[0128] Example 2

[0129] Figure 5This is a flowchart illustrating the first biosafety system disinfection method provided in this application embodiment, as shown below. Figures 1 to 5 As shown in the embodiments of this application, a disinfection method for a biosafety system is also provided, for use in the aforementioned biosafety system, the method comprising:

[0130] S101: Determine the pressure status of the outdoor air outlet of the biosafety cabinet in the biosafety system.

[0131] It should be noted that the outdoor air outlet is used to allow polluted gas inside the housing 110 to flow to the outside through the outdoor air outlet 115.

[0132] When the pressure at the outdoor air outlet 115 reaches a certain value, it means that the amount of disinfection gas entering the biosafety cabinet has reached the required level, further indicating that the disinfection of the biosafety cabinet room has reached the standard or preset state.

[0133] S102: Control the disinfection status of the biosafety system based on the pressure status of the outdoor air outlet.

[0134] It should be noted that when the disinfection gas inside the disinfection cabinet 200 circulates back and forth within the cabinet body 210 and the box body 110, after a long period of time, a certain pressure will exist at the outdoor air outlet 115 of the biosafety cabinet 100. When the pressure at the outdoor air outlet 115 of the biosafety cabinet 100 reaches the preset pressure value, it means that the amount of disinfection gas injected into the box body 110 has reached the required amount for disinfection, which is reflected in the pressure at the outdoor air outlet 115 reaching the preset pressure value. At this point, it indicates that the disinfection of the biosafety cabinet 100 has reached the standard. Open the outdoor air outlet 115 and close all connecting ports to end the disinfection process.

[0135] Furthermore, it should be noted that the method provided in this application first determines the pressure state of the outdoor air outlet of the biosafety cabinet in the biosafety system, and then controls the disinfection state of the biosafety system based on the pressure state of the outdoor air outlet.
