DETAILED DESCRIPTION

[0020] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but cannot be used to limit the protection scope of the present invention.

[0021] Embodiment 1: Figures 1 to 14As shown, the present invention provides a laboratory air disinfection and sterilization device, including a chassis 11 and a support base 21, the chassis 11 provides a support foundation for the entire device, the support base 21 is installed above the chassis 11, and a disinfection box 301 and a disinfection cover plate 302 are arranged on the support base 21, and the two are detachably connected, thereby forming a first disinfection chamber. In this first disinfection chamber, a plasma generator 22 is installed, and the plasma generator 22 can perform preliminary treatment on the air in the first disinfection chamber. The active particles in the plasma can actively attack and kill various microorganisms in the air, including bacteria, viruses, fungi, etc., effectively making up for the defect of weak ultraviolet penetration, and can also play a good role in disinfecting microorganisms hidden in the object shielding area; the plasma generator 22 can adopt the Cellume NCCO-1500C plasma generator. Air intake components are symmetrically arranged on both sides of the support base 21, and the air intake components are responsible for introducing external air, which reduces the disinfection blind area to a certain extent. Multiple groups of first air inlet pipes 303 and second air inlet pipes 304 are arranged in the disinfection box 301 to ensure that air can enter each area in the disinfection box 301 evenly and smoothly. A support frame 41 is arranged above the support seat 21, and the protective covers 42 on both sides thereof cooperate with the support frame 41 through a rotatable connection mode to construct a second disinfection chamber. At the same time, the protective cover 42 is driven by a motor to realize automatic unfolding operation. The first disinfection chamber and the second disinfection chamber are connected with the help of the first air pump 23 to achieve efficient air communication, ensuring the orderly flow of air between different disinfection areas. The ultraviolet component arranged in the second disinfection chamber is a key component for further deep purification of the air. The multiple groups of exhaust ports 43 evenly distributed on the top of the support frame 41 enable the pure air after thorough disinfection and sterilization to be discharged smoothly from the device and achieve good interaction with the external environment. On one side of the support frame 41, multiple groups of placement boxes are arranged intimately, which can be used to store items, tools, etc. related to experiments or disinfection, so that users can use them at any time. The controller on the other side is used to control different components. The user can use it to adjust the various operating parameters of the device, such as air intake, disinfection time, fan speed, etc., to adapt to different experimental scenarios and disinfection needs, to ensure that the device is always in the best working state, and to provide a safe and clean air environment for the laboratory. The controller can use the CJ2M-CPU11 controller of the Omron CJ2M series; at the same time, the entire device is mainly powered by an external power supply.

[0022] like Figure 2 , Figure 8 , Fig. 9 , Fig.11As shown, the air intake assembly includes an air intake funnel 501 and multiple groups of first fans 502. An air intake housing 24 is provided on both sides of the support seat 21. The air intake funnel 501 is cleverly snapped into the air intake housing 24 to form a stable air intake structure foundation. The air intake box 503 located on one side of the air intake funnel 501 has an opening surface located inside the air intake funnel 501, and the two are interconnected to ensure that air can flow smoothly between the two. The opening surface of the air intake box 503 is equipped with an assembly plate 504, and the assembly groove 505 provided on the assembly plate 504 provides an installation position for the first fan 502, and the first fan 502 is snapped into the assembly groove 505. Its air intake end faces the opening surface of the air intake funnel 501 so as to inhale the outside air, and the air outlet end faces the air intake box 503, and the inhaled air is pushed into the air intake box 503 forcefully. Subsequently, the air inlet box 503 is connected to the multiple groups of first air inlet pipes 303 through multiple groups of connecting pipes, so that the air is smoothly introduced into the disinfection box 301 for subsequent disinfection treatment.

[0023] The air intake assembly also includes a first dustproof net 506 and a protective baffle 507. The connecting slot 508 provided on the air intake housing 24 allows the first dustproof net 506 to pass through and be stuck in the air intake housing 24. The first dustproof net 506 can effectively block large dust particles in the air and prevent them from entering the device, thereby ensuring the normal operation and service life of the device; and the setting of the connecting slot 508 makes it easy to clean and replace the first dustproof net 506. Long-term use can easily cause excessive adsorption of impurities in the first dustproof net 506, causing blockage and affecting the quality of the inhaled air. The protective baffle 507 is also stuck in the air intake housing 24, and is located between the first dustproof net 506 and the air intake funnel 501, and is arranged in sequence with the two. There are multiple groups of air intake grooves on the protective baffle 507. While ensuring the normal circulation of air, these air intake grooves also play a certain buffering and guiding role. The protective baffle 507 plays an effective protective role to prevent the first dustproof net 506 from being damaged by external forces. The movable slot 509 provided at one end of the air inlet housing 24 provides a movable space for the movable frame 510. The movable frame 510 is smoothly inserted into the movable slot 509 and the air inlet housing 24, and can be slidably connected with the air inlet housing 24. A movable plate 511 is provided at one end of the movable frame 510, and a plurality of scrapers 512 are installed on one side of the movable plate 511. The scrapers 512 are inserted into the air inlet groove. When the air inlet groove needs to be cleaned and maintained, the scrapers 512 can easily scrape off dust or impurities that may be accumulated in the air inlet groove by sliding the movable frame 510, ensuring that the air inlet groove is always unobstructed, thereby maintaining the stable air intake performance of the air inlet assembly, and laying a foundation for the continuous and efficient operation of the entire device.

[0024] like Figure 2 , Figure 6 , Fig. 9As shown, the two ends of the support seat 21 are symmetrically provided with air intake parts, and multiple groups of second air pumps 25 are installed on the chassis 11, which form connection passages with the air intake parts and the second air intake pipe 304 through air guide pipes. The air intake part includes an air intake seat 61, and an air intake cavity is arranged inside it. This air intake cavity is seamlessly connected with the second disinfection cavity, ensuring the smooth flow of air between different chambers. An air intake head 62 is arranged on the top of the air intake seat 61, and a second dustproof net 63 and an air intake cover 64 are installed on the top of the air intake head 62, wherein the second dustproof net 63 is stuck in the air intake head 62, which can effectively block fine dust particles in the air and prevent them from entering the interior of the device, thereby maintaining the cleanliness and operation stability of the device. At the bottom of the air intake head 62, the rubber sheet 65 is connected to the air intake head 62 by contact, thereby forming the effect of a one-way valve; at the same time, the first air intake pipe 303 and the second air intake pipe 304 are also provided with rubber sheets 65 to form a one-way flow to avoid the backflow of gas.

[0025] Air inlets 66 are provided on both sides of the air inlet seat 61. The air inlet 66 is equipped with a second fan 67. As one of the power sources for air intake, the second fan 67 can actively inhale external air. On one side of the second fan 67, a third dustproof net 68 is stuck in the air inlet 66. It cooperates with the second dustproof net 63 to form a double dustproof barrier, further improving the purity of the air intake. In addition, a battery is provided on one side of the air inlet seat 61, so that the air intake component can still rely on its own battery power supply in certain special circumstances, such as short power outages or mobile use, to maintain the normal operation of the second fan 67, ensure the continuous stability of the air intake function, and provide strong support for the reliable operation of the entire device in a variety of complex environments. When the air intake component is placed far away from the device, the input of air can be guaranteed by the action of the second fan 67.

[0026] like Figure 2 , Fig. 9 , Fig.10 As shown, multiple groups of first partitions 305 are arranged inside the disinfection box 301, and the second partitions 306 at the bottom of the disinfection cover 302 cooperate with each other. The multiple groups of first partitions 305 are located between the second partitions 306, and the plasma generator 22 and the first air inlet pipe 303 and the second air inlet pipe 304 are all located in the area defined by the multiple groups of first partitions 305. Multiple groups of limit blocks 307 are also arranged in the disinfection box 301, and the plasma generator 22 can be stably stuck between these limit blocks 307, which not only ensures the stability of the plasma generator 22 during operation, but also facilitates its installation, disassembly and maintenance.

[0027] A special air passage is formed between the first partition 305 and the second partition 306, and the air can flow in an orderly manner. Partition plates 308 are provided on the corresponding surfaces of the first partition 305 and the second partition 306, one group of partition plates 308 faces downward, and the other group of partition plates 308 faces upward, so that the two groups of partition plates 308 together construct a Z-shaped channel. When the air passes through this Z-shaped channel, the flow path is effectively extended, thereby increasing the contact time between the air and the plasma generator 22, so that the active particles in the plasma can more fully interact with various microorganisms in the air, thereby improving the effect and efficiency of disinfection.

[0028] like Figure 3 As shown, both ends of the disinfection box 301 are provided with a vent pipe 309, which is located at one end of the air passage, and two groups of vent heads 44 are provided on the support frame 41, one end of the vent head 44 goes deep into the second disinfection chamber, and the other end leads to the outside world. The first air pump 23 is firmly mounted on the support frame 41, and it is connected with the vent head 44 and the vent pipe 309 respectively through the ventilation conduit, and under its effect, the stable transmission of air from the disinfection box 301 to the second disinfection chamber is realized. In the second disinfection chamber, a vent tank 45 is also provided, and the vent tank 45 and the vent head 44 are detachably connected, which facilitates the cleaning, replacement and maintenance of the vent tank 45. There are multiple groups of through grooves on the vent tank 45, and these through grooves can make air evenly dispersed in the vent tank 45, further optimizing the disinfection process of air in the second disinfection chamber, ensuring that air can be fully irradiated with ultraviolet rays and purified in every corner, thereby ensuring the comprehensiveness and effectiveness of the whole device to air disinfection and sterilization.

[0029] like Figure 2 , Figure 5 , Fig.12As shown, the ultraviolet light assembly includes a mounting rod 71 and multiple groups of first ultraviolet light modules 72 and multiple groups of second ultraviolet light modules 73. Two groups of first frames 74 and two groups of second frames 75 are arranged around the mounting rod 71, and the first frames 74 and the second frames 75 are in a vertically distributed form, so that the ultraviolet light module can irradiate and disinfect the air from multiple directions without leaving dead corners. A slide rail 76 is arranged inside the first frame 74 and the second frame 75, and an electric slider 77 is slidably arranged on the slide rail 76. The first ultraviolet light module 72 and the second ultraviolet light module 73 are respectively stably mounted on the electric slider 77. With the free sliding of the electric slider 77 on the slide rail 76, the positions of the first ultraviolet light module 72 and the second ultraviolet light module 73 can be flexibly adjusted according to the actual disinfection needs, thereby realizing the precise control of the ultraviolet irradiation range and intensity, so that it can perfectly adapt to laboratory spaces of different volumes and layouts. In addition, the length of the second frame 75 is greater than that of the first frame 74, and third ultraviolet lamp modules 78 are thoughtfully arranged on both sides of the second frame 75, while the second ultraviolet lamp module 73 is located between the two groups of third ultraviolet lamp modules 78, forming a unique ultraviolet lamp module layout, which further enhances the comprehensiveness and effectiveness of ultraviolet disinfection; the ultraviolet lamp module structure is mainly composed of an outer frame and multiple groups of ultraviolet lamps inside, and ultraviolet disinfection is achieved through ultraviolet lamps; at the same time, the ultraviolet lamps on the third ultraviolet lamp module 78 are set as a double-layer structure and arranged crosswise to further increase the disinfection range.

[0030] In the second disinfection chamber, the mounting plate 310 is mounted on the top of the support frame 41, and the mounting groove 312 is provided on the mounting plate 310, and the third fan 311 is installed therein and is located below the exhaust port 43. The main function of the third fan 311 is to provide power support for the discharge of air, ensuring that the air after disinfection can be discharged from the second disinfection chamber in a timely and smooth manner. Above the support frame 41, two groups of exhaust pipes 313 are symmetrically arranged, and one end of the exhaust pipe 313 is connected to the exhaust port 43, so that the second disinfection chamber and the exhaust pipe 313 are connected. Multiple groups of exhaust grooves 314 are provided on both sides of the exhaust pipe 313, and these exhaust grooves 314 can make the exhausted air more evenly dispersed into the external environment, avoiding the adverse effects on the surrounding environment caused by the local airflow being too fast or too strong, and also helping to maintain the stability and balance of the airflow inside the laboratory, creating a more comfortable and safe air environment for the laboratory; the exhaust groove 314 is a unique Z-shaped structure, which effectively avoids external impurities and directly enters the second disinfection chamber through the exhaust groove 314.
