The display screen 7 can be used for displaying the working state of the plasma generator and the ozone generator, and the control device can be used for controlling the display content of the display screen 7.

The killing principle of the plasma generator is as follows: water molecules in the air generate a large amount of free radicals such as OH through plasmas, the hydroxyl free radicals are attached to the surfaces of microorganisms such as bacteria and viruses through redox reaction and can generate double bond reaction with cell walls of the bacteria to damage cell membranes of the bacteria and enter the bacteria, and the double bond reaction acts on cell proteins and lipopolysaccharides to cause cell lysis and death, so that sterilization is realized; in the case of viruses, hydroxyl radicals directly destroy genetic material (RNA/DNA) by breaking the lipid envelope and capsid, rendering them incapable of replication and killing viruses.

The purification principle of the plasma generator is as follows: 1) Decomposition of organic gas: under the catalytic action of a strong electric energy field and oxides, molecules of harmful gases are quickly dissociated, atoms of the harmful gases are continuously ionized under the catalysis of the electric energy field and the oxides, chemical bonds among the atoms are broken in the process, and then the atoms are recombined into new substances according to the characteristic relationship among the atoms (for example, hydroxyl radicals can degrade formaldehyde into water molecules and carbon dioxide); 2) Removing particulate matters: the energetic electrons in the plasma contact with the solid pollutants to charge the solid pollutants, and the solid pollutants are combined into large particles in the mutual collision process and deposited on a dust collecting part arranged at the lower end in the machine shell 1.

Ozone disinfection principle: ozone acts on cell membranes of microorganisms such as bacteria, and causes damage to the cell membranes, metabolic disorder, and growth inhibition. Ozone breaks through the cell membrane and continues to permeate, then lipoprotein and lipopolysaccharide in the membrane are destroyed, the cell permeability is changed, and the organism is killed. Ozone killing viruses is the oxidation that directly destroys the genetic material (RNA/DNA) and thereby kills the virus.

Plasma and ozone can play the effect of disinfecting and disinfecting, but ozone is more obvious to the effect of killing on the object surface in the ambulance medical compartment, therefore, when the ambulance is ready, the ozone generator of the disinfection machine of the embodiment can be used for killing, the ozone generator can realize comprehensive disinfection of air and object surfaces after continuously killing for 30min, in order to avoid the harm of ozone to medical personnel, ozone is basically and completely attenuated after shutdown for 30min, and at the moment, the medical compartment can be used.
