The bacteria and virus detector comprises a shell 8, a laser 9, a micro-fluidic chip 10, a sample collecting element 11 and a Raman spectrum detection platform 12, wherein the laser, the micro-fluidic chip 10, the sample collecting element and the Raman spectrum detection platform are arranged in the shell, the sample collecting element is connected with the micro-fluidic chip, and the Raman spectrum detection platform is electrically connected with the input end of the controller. The Raman spectrum detection platform comprises a platform main body, a Rayleigh filter, a grating, a CCD detector, a machine learning processing algorithm module and a Raman spectrum database module. An excitation light source irradiates a bacterial and viral region, the bacterial and viral region is subjected to surface scattering and then enters the platform main body to form corresponding surface enhanced scattered light with a bacterial and viral characteristic spectrum, the surface enhanced scattered light is filtered by the Rayleigh filter, and then is subjected to grating light splitting, and then fine spectral distribution corresponding to the surface enhanced scattered light is obtained by the CCD detector, microorganism identification information is obtained by the machine learning processing algorithm module according to a Raman spectrum database of the Raman spectrum database module and the fine spectral distribution and is transmitted to the controller, and the controller realizes information transmission and control with the Raman spectrum detection platform through the Internet of things technology.
The purification sterilizer comprises a first-level filtering component, a second-level filtering and sterilizing component, a third-level filtering and sterilizing component and a fourth-level filtering and sterilizing component which are sequentially arranged along the wind direction.
The primary filtering component is an active carbon filter screen 13 which is arranged at the outlet end of the air guide sleeve.
The second grade filters and the sterilization subassembly includes LED ultraviolet sterilization lamp plate 14 and HEPA high efficiency filter screen 15, and LED ultraviolet sterilization lamp plate is laid along the even interval of shell body inner wall circumference.
The third filtering and sterilizing component comprises primary filter cotton 16 and a high-temperature sterilizing piece, wherein the high-temperature sterilizing piece consists of a metal filter screen 17 and an insulated electric heating wire 18 wound on the metal filter screen. High temperature is also an effective method for sterilization and disinfection, and can make up for the defect that ultraviolet and ozone sterilization needs longer air residence time. The principle is mainly based on two aspects: firstly, the high temperature can lead the protein forming the living body to generate irreversible denaturation, lead enzymes to be inactivated and cause irreversible damage to the cell structure of the living body; ② the DNA of the genetic material will also be decomposed at high temperature, causing the death of bacteria and virus.

TiO 22The photocatalyst has no toxicity to microbial cells, has the function of killing bacteria only under the irradiation of light, particularly ultraviolet light, and is called as photocatalytic sterilization. Photocatalytic sterilization has two different mechanisms of direct and indirect reactions: the direct reaction mechanism is that the photo-generated electrons and the photo-generated holes directly react with the cell wall, the cell membrane or the components of the cell,resulting in the inactivation of the functional unit and cell death. The indirect reaction mechanism is that photo-generated electrons or photo-generated holes react with water or dissolved oxygen in the water to form hydroxyl radical-OH and superoxide ions (O)2 -) And H2O2The equipotent oxidizing species, which chain react with cellular membranes and intracellular components, lead to cell death.
The air outlet pipe is provided with an electric air valve 21 and is electrically connected with the controller.
The use method of the purification and disinfection device of the combined air conditioning unit is characterized by comprising the following steps:
the controller effectively identifies the information transmitted by the bacterial virus detector, four risk levels are divided according to a set killing standard, the higher the level is, the greater the risk is, and when the controller judges that the risk level is one level, the air only needs to be filtered by a first-level filtering component; when the risk level is the second level, the LED ultraviolet sterilization lamp panel is started by the controller, and the HEPA high-efficiency filter screen is installed manually; when the risk level is three-level, installing primary filter cotton and a high-temperature disinfection piece, and starting an insulated electric heating wire by a controller; when the risk level is four, installing a UV-C ultraviolet germicidal lamp and TiO2The photocatalytic filter screen and the controller start the UV-C ultraviolet germicidal lamp; when the purifying sterilizer operates, the controller starts the fan, the primary filter cotton and the metal filter screen effectively intercept bacteria and viruses in the air, and when the controller closes the fan, the insulating electric heating wire simultaneously heats the primary filter cotton and the metal filter screen to 120-150 ℃ to sterilize the attached bacteria and viruses at high temperature. The air after the purification and disinfection treatment enters the room through the air outlet pipe, and the volume of the disinfection and sterilization room is larger than that of the air outlet room, so that the smoothness of air flow can be increased, and the air flow resistance in the pipeline is reduced.
The filter screen design of every module becomes can dismantle the mode, and the module combination that uses when reaching different disinfection and isolation purifying effect is different, to the module that does not use, we retrieve its filter plate, and manual installation has improved the life of device again when needs, and the washing and the change of the filter screen of also being convenient for simultaneously are high-efficient convenient.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
