Detailed Description
The existing common disinfection method mainly comprises ultraviolet lamp direct irradiation and artificial spraying chemical disinfection, and ultraviolet light of UVC wave band emitted by the ultraviolet lamp has strong DNA or RNA damage effect on microorganisms, thereby achieving the disinfection purpose. The chemical disinfectant sprayed manually is mainly used for generating oxidation reaction with microorganisms by utilizing the strong oxidizing property of the chemical disinfectant, so that the microorganisms finally change the property to achieve the aim of disinfection.
The inventor finds that the defects of the two disinfection methods are obvious, and the ultraviolet lamp direct irradiation method cannot disinfect a large amount of air in a large range due to the limited radiation range of the ultraviolet lamp, is not suitable for public places with large areas, and can damage human bodies due to the fact that the ultraviolet lamp directly irradiates the human bodies for a long time; the method for manually spraying the chemical disinfectant has the advantages that the chemical disinfectant is corrosive, stimulation and even damage are easily caused to the respiratory mucosa of a human body, the damaged respiratory tract is more easily infected by virus and bacteria, the problem that the stimulation is too strong or the components are too rare to lose the disinfection capacity easily occurs under the condition that the concentration of the artificial proportioning concentration cannot be avoided, meanwhile, the time for killing the virus and bacteria by the chemical disinfectant still needs 30-60 minutes under the condition that the concentration proportioning is completely correct, the virus and bacteria can be killed, and the medicine property is obviously attenuated along with the continuous natural volatilization of the chemical disinfectant until the disinfection capacity is completely lost. And the two existing disinfection methods do not have the ability of actively disinfecting a large amount of air and the surfaces of objects.
The inventor finds that when all people in a public place are in use, the motor continuously provides aerodynamic force to suck air in the public place, the air is sucked into the air disinfection module continuously operated by the second machine body after being filtered and deodorized by the air purification module, the air is disinfected in the air disinfection module for three times and then sent back to the first machine body, and the air after being filtered, deodorized and disinfected for three times is sent back to the public place from the main air supply port of the first machine body; when no person is in the public place, the first machine body and the second machine body stop running after delaying 180 seconds, the third machine body is started to run for a disinfection time period, the disinfection time interval can be set, the lower limit is 1 minute, the upper limit is 5 minutes, the third machine body can not repeatedly run after the third machine body runs for one disinfection time interval or when any human body sensor detects that the running is interrupted by people, the next running needs to go from people to no people again, when an arbitrary human sensor detects someone, the controller can assign the instruction of stop operation at once to the third organism, and the third organism utilizes pulse highlight sterilization module to carry out quick, thorough disinfection to air and object surface initiative when moving, and the design of 180 seconds of cooperation first organism, second organism delayed operation has further ensured the disinfection quality, further improves the holistic disinfection efficiency of device and disinfection quality.
