DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] The core of the utility model is to provide an air microorganism identification device, which has a short detection cycle for microorganisms and can provide real-time feedback of detection results. Another core of the utility model is to provide an air microorganism identification method applied to the above air microorganism identification device, which can realize real-time detection of microorganisms.

[0040] Please refer to Figure 1-Figure 4 The embodiment of the utility model provides an air microorganism identification device, including a microorganism acquisition device, a shooting device 3 and an intelligent identification device 4. The microorganism acquisition device is used to acquire microorganisms in the air; the shooting device 3 is used to take pictures of the microorganisms; the intelligent identification device 4 is connected to the shooting device 3, and is used to receive the pictures taken by the shooting device 3, and process the pictures to obtain the types and quantities of the microorganisms.

[0041] That is to say, when the air microorganism identification device is working, the microorganism acquisition device acquires the microorganisms in the air, the shooting device 3 takes pictures of the microorganisms, and sends the pictures of the microorganisms to the intelligent identification device 4, and the intelligent identification device 4 processes the pictures of the microorganisms to obtain the types and quantities of the microorganisms.

[0042] It can be seen that the air microorganism identification device combines the microorganism acquisition device, the shooting device 3 and the intelligent identification device 4. After acquiring the microorganisms in the air, the type and quantity of the microorganisms are automatically obtained by automatically taking pictures of the microorganisms and processing and analyzing the pictures. That is, the type and quantity of the microorganisms are automatically identified by using the photography technology and image processing technology, and the real-time detection of the microorganisms in the air is realized, the detection cycle is shortened, and the detection results can be fed back in real time. Especially for special periods when various airborne diseases such as pneumonia and influenza A are prevalent, the pathogenic bacteria can be accurately monitored, and the air quality of medical and health institutions can be monitored in real time to ensure the safe operation of medical and health institutions. Moreover, it avoids relying on manpower to record the number of bacterial colonies, saves time and effort, and also avoids the uncertainty caused by human records, thereby improving the detection accuracy.

[0043] It should be noted that the present embodiment does not limit the specific structure of the microorganism acquisition device, as long as it can acquire microorganisms in the air.

[0044] In some embodiments, the microorganism acquisition device includes a collector 1 and a bacteria storage 2. The collector 1 is used to collect microorganisms in the air; the bacteria storage 2 is used to align with the collector 1 and the shooting device 3 in sequence, so as to receive the microorganisms when the bacteria storage 2 is aligned with the collector 1; and when the bacteria storage 2 is aligned with the shooting device 3, the shooting device 3 can take pictures of the microorganisms. That is to say, in this embodiment, the microorganisms collected by the collector 1 are stored in the bacteria storage 2, and the microorganisms are finally obtained by the bacteria storage 2 and carried. The bacteria storage 2 plays the role of transferring the collector 1 and the shooting device 3, so that the microorganisms collected by the collector 1 can be photographed by the shooting device 3.

[0045] It is understandable that, before use, the bacteria storage device 2 needs to be sterilized so that the sterilized bacteria storage device 2 can be used to store microorganisms in the air.

[0046] In addition, it should be noted that the present embodiment does not limit the specific structure and working principle of the collector 1, as long as the collector 1 can collect microorganisms in the air. In some embodiments, the collector 1 is a six-stage sieve hole impact air microorganism sampler. The six-stage sieve hole impact air microorganism sampler can accurately and quickly capture and separate microorganisms in the air, providing important support for microbiological research and environmental monitoring. Of course, the collector 1 can also use other air collectors 1 that can obtain microorganisms in the air.

[0047] Furthermore, the present embodiment does not specifically limit the method for transferring the bacteria storage container 2 between the collector 1 and the photographing device 3. For example, the collector 1 and the photographing device 3 may be independent discrete structures, and the bacteria storage container 2 may be manually taken and transferred between the collector 1 and the photographing device 3 so that the bacteria storage container 2 is aligned with the collector 1 and the photographing device 3 in turn.

[0048] Considering the convenience of transferring the bacteria storage 2, in some embodiments, the air microorganism identification device further includes a transfer device 5, which is used to transfer the bacteria storage 2, so as to transfer the bacteria storage 2 to the bottom of the collector 1 and the shooting device 3 in sequence. That is, in this embodiment, the transfer device 5 is used to automatically transfer the bacteria storage 2, so that the bacteria storage 2 is aligned with the collector 1 and the shooting device 3 in sequence, and the automatic operation is realized. It should be noted that the specific structure of the transfer device 5 is not limited in this embodiment, as long as the transfer of the bacteria storage 2 can be realized. For example, in some embodiments, the transfer device 5 includes a moving guide rail, and the collector 1 and the shooting device 3 are arranged above the moving guide rail at intervals along the moving direction of the moving guide rail. That is, after the bacteria storage 2 is placed on the moving guide rail, the bacteria storage 2 can be sequentially transferred to the bottom of the collector 1 and the bottom of the shooting device 3 through the moving guide rail. When the bacteria storage 2 moves to the bottom of the collector 1, the microorganisms collected by the collector 1 can be obtained; when the bacteria storage 2 moves to the bottom of the shooting device 3, it can be photographed by the shooting device 3. In addition, there are limit plates on both sides of the moving guide rail, which can guide the movement of the bacteria storage 2 and prevent the bacteria storage 2 from leaving the moving guide rail. Of course, in other embodiments, the transfer device 5 can also be other mechanisms with a transmission function, for example, the transfer device 5 can be a manipulator, a robot, a conveyor belt, a pulley, and other structures.

[0049] In addition, in order to facilitate the acquisition of the bacteria storage 2, in some embodiments, the air microorganism identification device further includes a storage box 6, which is used to store the stacked bacteria storage 2. That is, in this embodiment, the bacteria storage 2 is stored in the storage box 6, and when in use, the bacteria storage 2 is obtained one by one from the storage box 6, so that the microorganisms are detected once every period of time, so as to realize long-term continuous monitoring of the monitoring environment.

[0050] Furthermore, in order to automatically obtain the bacteria storage container 2 in the storage box 6, in some embodiments, the side of the storage box 6 is provided with an outlet 61 that is docked with the entrance of the transfer device 5, and the storage box 6 is also provided with a horizontal pushing member 7 and a vertical pushing member 8. The horizontal pushing member 7 is used to push the top bacteria storage container 2 from the outlet 61 of the storage box 6 to the transfer device 5; the vertical pushing member 8 is used to lift the stacked bacteria storage containers 2 as a whole so that the top bacteria storage container 2 is aligned with the outlet 61 of the storage box 6. That is to say, during operation, the lateral pusher 7 pushes the top bacteria storage container 2 from the outlet 61 of the storage box 6 to the transfer device 5, and the transfer device 5 sequentially transfers the bacteria storage container 2 to the bottom of the collector 1 and the photographing device 3; when the top bacteria storage container 2 in the storage box 6 is pushed out of the outlet 61 of the storage box 6, the lateral pusher 7 is reset, and the vertical pusher 8 is actuated to lift the stacked bacteria storage containers 2 as a whole, so that the top bacteria storage container 2 is aligned with the outlet 61 of the storage box 6, so as to push the next bacteria storage container 2 from the outlet 61 of the storage box 6 to the transfer device 5. It can be seen that this embodiment can realize the automatic discharge of the bacteria storage container 2.

[0051] It should be noted that the present embodiment does not limit the specific structure of the lateral pushing member 7 and the vertical pushing member 8. As long as the lateral pushing member 7 can be moved laterally to push the top bacteria storage container 2 from the outlet 61 of the storage box 6 to the transfer device 5, and the vertical pushing member 8 can be moved up and down to lift the stacked bacteria storage containers 2 as a whole so that the top bacteria storage container 2 is aligned with the outlet 61 of the storage box 6, it will be sufficient.

[0052] In addition, in some embodiments, the air microorganism identification device further includes a storage box 9, which is used to store the photographed bacteria storage 2. It is understandable that after the bacteria storage 2 is photographed by the shooting device 3, the microorganisms in the bacteria storage 2 are detected microorganisms and can be discarded. In this embodiment, the storage box 9 is used to temporarily store the photographed bacteria storage 2, which is convenient for centralized processing of discarded microorganisms, that is, the storage box 9 needs to be cleaned regularly.

[0053] In some embodiments, the storage box 9 is disposed at the outlet end of the transfer device 5, so that the transfer device 5 can be used to transfer the bacteria storage device 2 to the storage box 9, thereby facilitating the automatic transfer of the bacteria storage device 2 between various workstations.

[0054] In addition, in some embodiments, the air microorganism identification device further includes a housing 10, the housing 10 includes a sampling space and an internal space separated from each other, the collector 1 is arranged in the sampling space, and the bacteria storage 2, the shooting device 3 and the intelligent identification device 4 are all arranged in the internal space. That is to say, in this embodiment, the housing 10 is used to carry and accommodate the collector 1, the bacteria storage 2, the shooting device 3 and the intelligent identification device 4, and the collector 1, the bacteria storage 2, the shooting device 3 and the intelligent identification device 4 are integrated into one, and by dividing the housing 10 into the sampling space and the internal space, it is helpful to ensure the sampling environment of the collector 1, and at the same time ensure the environment of the internal space where the bacteria storage 2, the shooting device 3 and the intelligent identification device 4 are set.

[0055] Furthermore, in some embodiments, the housing 10 is provided with an air inlet 11, an air inlet channel connected to the air inlet 11, and an air outlet 12 connected to the internal space. The air inlet channel is provided with a fan 13, and a filter 14 is provided at the position where the air inlet channel is connected to the internal space. When working, the fan 13 works to suck the air outside the housing 10 into the air inlet channel through the air inlet 11. The air entering the air inlet channel is filtered by the filter 14, and enters the internal space after reaching the sterility level, and finally discharged through the air outlet 12, so as to ensure that the internal space of the housing 10 is always in a sterile environment, so that the bacteria storage device 2 circulates in a sterile environment, and the internal space of the housing 10 is always kept at a positive pressure, so as to avoid the influence of external pollutants on the detection results during the identification of air microorganisms, thereby ensuring the stability and safety of the detection results.

[0056] It should be noted that the specific structure and working principle of the filter 14 are not limited in this embodiment, as long as the air can be filtered to allow sterile air to enter the internal space of the housing 10. For example, the filter 14 is a high-efficiency filter 14, a plasma filter 14 or an ultraviolet purifier and disinfector.

[0057] In addition, in order to reduce the effect of the filter 14 on the microbial content of the bacteria storage 2, in some embodiments, the air outlet 12 of the housing 10 is connected to the air inlet 11 through a pipe, and the pipe is located outside the housing 10. That is, in this embodiment, the sterile air is circulated through the external pipe to reduce the effect of the filter 14 on the microbial content of the bacteria storage 2.

[0058] Furthermore, in some embodiments, the housing 10 is provided with a display screen 15, which is connected to the intelligent recognition device 4 and is used to display the type and quantity of microorganisms. That is, the intelligent recognition device 4 processes the photo of the microorganism, obtains the type and quantity of the microorganism, and then sends the type and quantity of the microorganism to the display screen 15, which is displayed on the display screen 15, so as to timely remind the user to handle it, facilitate the search for the infection source of airborne diseases and cut off the infection route, and play an important role in the control and detection of air microorganisms in hospitals.

[0059] It should be noted that in the embodiment of the utility model, the specific structure of the photographing device 3 is not limited, as long as it can take pictures of microorganisms. In some embodiments, the photographing device 3 is an electron microscope. That is, this embodiment uses an electron microscope to take pictures of microorganisms.

[0060] In addition, the embodiment of the utility model does not limit the specific structure of the intelligent recognition device 4, as long as the intelligent recognition device 4 can process the photos of microorganisms and obtain the type and quantity of microorganisms. The intelligent recognition device 4 may include a processor, a computer, etc. For example, with the development of technology, the intelligent recognition device 4 may be an AI intelligent analysis and recognition device, that is, the AI ​​intelligent analysis and recognition device can effectively recognize the type and quantity of microorganisms in the photographed photos after long-term training.

[0061] Furthermore, the intelligent recognition device 4 is connected to an indoor air sterilizer. When the intelligent recognition device 4 detects that the content of pathogenic bacteria in the microorganisms is higher than a preset value, the indoor air sterilizer is automatically turned on for disinfection.

[0062] In addition, the intelligent recognition device 4 can also be connected to a terminal device such as a computer or a mobile phone, so that after the intelligent recognition device 4 detects the set pathogenic bacteria, it can remind the user through the terminal device such as a computer or a mobile phone.

[0063] In addition, the intelligent identification device 4 can also be connected to an alarm so that after the intelligent identification device 4 detects the set pathogenic bacteria, the alarm is sounded through the alarm to remind the user.

[0064] In addition to the above-mentioned air microorganism identification device, the present invention also provides an air microorganism identification method applied to the air microorganism identification device disclosed in the above-mentioned embodiment, and the air microorganism identification method includes:

[0065] Using a microorganism acquisition device to acquire microorganisms in the air;

[0066] Taking a picture of the microorganism using the camera 3;

[0067] The photos taken by the shooting device 3 are processed by the intelligent recognition device 4 to obtain the types and quantities of microorganisms.

[0068] That is to say, when working, the microorganisms in the air are obtained by using the microorganism acquisition device, and the microorganisms are photographed by the shooting device 3, and then the photos of the microorganisms taken by the shooting device 3 are processed by the intelligent identification device 4 to obtain the type and quantity of the microorganisms, thereby realizing real-time detection of microorganisms in the air, shortening the detection cycle, and being able to feedback the detection results in real time, especially for special periods when various airborne diseases such as pneumonia and influenza A are prevalent, pathogenic bacteria can be accurately monitored, and the air quality of medical and health institutions can be monitored in real time to ensure the safe operation of medical and health institutions. Moreover, it avoids relying on manpower to record the number of bacterial colonies, saves time and effort, and also avoids the uncertainty caused by human records, thereby improving the detection accuracy.
