Description

Detection device and air conditioner The present application claims priority from chinese patent application CN202410235677.7 filed on month 03 of 2024 and 01, entitled "bacterial detection module", the entire contents of which are incorporated herein by reference. Technical Field The utility model relates to the technical field of bacteria detection, and particularly provides a detection device and an air conditioner. Background More or less microorganisms are present in the air, which are usually attached to dust or droplets, and as dust and droplets are suspended in the air, the presence of these microorganisms can cause the air to be a medium for transmitting respiratory diseases, seriously jeopardizing the physical health of people. For the physical health of people, the number of microorganisms in the air needs to be detected, and when the number of microorganisms exceeds the standard, corresponding measures are taken in time to reduce the number of microorganisms. At present, when detecting the number of microorganisms in air, a specific sampler is generally required to be used for sampling, and the sampled air sample is cultured by a culture medium and then counted. The common detection methods for detecting bacteria mainly comprise a sedimentation plate method, a liquid impact method, an impact plate method and a membrane filtration method, wherein the sedimentation plate method is to place a plate containing an agar culture medium at a place to be detected, open a plate cover for a certain time, then culture, and count the colony number. The liquid impact method is also called as absorption tube method, which absorbs quantitative air into the absorption liquid in the tube, then takes a certain amount of the liquid, dilutes and carries out flat culture, counts the colony number or separates the pathogenic microorganism. The impact plate method is to suck quantitative air to impact one or several, rotating or non-rotating plate culture medium surfaces rapidly, then culture the plates and count the number of grown colonies. The membrane filtration method is to pass a certain amount of air through a special filter membrane supported on a filter, such as a nitrocellulose filter membrane, so that dust particles with microorganisms are attached to the surface of the filter membrane, then the dust particles trapped on the filter membrane are eluted in a proper solution, and then a certain amount of the solution is sucked for measuring the bacterial count. However, these methods of detection generally require sampling with a specific sampler and then culturing with a medium, which results in the detection of the bacterial count only being possible in a laboratory of detection qualification. During detection, a professional is required to sample on site, and then the sample is brought back to a laboratory for culture and detection, so that the defects of long detection period, incapacity of civilian use and the like are overcome. Accordingly, there is a need in the art for a new solution to the above-mentioned problems.
