detailed description

In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution of the utility model is clearly and completely described below in conjunction with the accompanying drawings in the example of the utility model. Obviously, the described example is only the utility model. Some examples of new types, but not all examples. Based on the examples in the present utility model, all other implementations obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

In the description of this embodiment, the terms "first" and "second" are only used to distinguish similar objects, and cannot be interpreted as a specific sequence or sequence. It should be understood that such usages can be interchanged under appropriate circumstances.

The example shown in Figure 1-4 provides a novel multi-functional disinfection machine suitable for disinfecting ambulances according to the utility model, including a casing 1, and an airflow passage as an independent space is separated by a partition in the casing 1 , the air inlet 1-1 and the air outlet 1-2 are set corresponding to the air flow channel on the casing, and the primary filter is set at the air inlet 1-1, and the air flow channel from the air inlet 1-1 to the air outlet 1-2 A plasma generator, an ozone generator, and a blower fan 3 are provided in sequence, and 2 in the figure is a plasma generator and an ozone generator, and the plasma generator and the ozone generator can be arranged side by side horizontally, wherein the plasma generator and the ozone generator can be selected to work The casing 1 outside the air flow channel is also provided with: a power supply unit for supplying power to the plasma generator, ozone generator and fan 3, and a control device connected to the power supply unit; the surface of the casing 1 is provided with an external power socket 6 , a display screen 7 and an operation button 8, wherein the display screen 7 and the operation button 8 are respectively connected to the control device, and the power socket 6 is connected to the power supply unit.

After the disinfection machine in this example is installed on the ambulance, when there is no one in the car, such as before leaving the car or after the task is over, the ozone generator can be used to fully disinfect the environment inside the car. Then you can use the plasma generator to disinfect the environment inside the car. When the ozone generator or plasma generator is working, the primary effect filter at the air inlet 1-1 first filters the air entering the airflow channel of the sterilizer to remove larger particle pollutants in the air, and the filtered air When flowing through the ozone generator or plasma generator, the ozone ions or positive and negative ions are carried into the interior space of the ambulance to realize the elimination of germs floating in the space and attached to the surface of objects in the car, thereby ensuring the ambulance The health and safety of the car environment.

It should be noted that, referring to Figure 1-2, under the action of the fan 3, the air enters the airflow channel from the air inlet 1-1 at the lower end of the casing 1 through the primary filter, and is sterilized by an ozone generator or a plasma generator. The final air is discharged into the medical cabin of the ambulance from the air outlet 1-2 on the upper end of the casing 1, thereby completing the circulation and disinfecting of the air in the medical cabin. The operation button 8 acts on the control device so as to achieve the purpose of switching the work of the plasma generator and the ozone generator. The display screen 7 can be used to display the working status of the plasma generator and the ozone generator, and the control device can be used to control the display content of the display screen 7 .

The disinfecting principle of the plasma generator: water molecules in the air pass through the plasma to generate a large number of free radicals such as OH, and the hydroxyl free radicals attach to the surface of bacteria, viruses and other microorganisms through oxidation-reduction reactions, and can react with double bonds on the cell walls of bacteria to destroy Bacterial cell membrane and enter its interior, acting on cell protein and lipopolysaccharide, causing cell lysis and death, and achieving sterilization; for viruses, hydroxyl radicals directly destroy their genetic material (RNA/DNA) by breaking their lipid envelope and capsid , so that it cannot be copied to achieve antivirus.

Purification principle of plasma generator: 1) Decomposition of organic gas: Under the catalysis of strong electric energy field and oxide, the molecules of harmful gas are rapidly dissociated, and its atoms are continuously ionized under the catalysis of electric energy field and oxide. Cause chemical bonds between atoms to break, and then recombine into new substances according to the characteristic relationship between atoms (for example, hydroxyl radicals can degrade formaldehyde into water molecules and carbon dioxide); 2) Particle removal: energy-carrying electrons in the plasma The contact with solid pollutants makes the solid pollutants charged, and they are combined into large particles in the process of collision with each other and deposited on the dust collecting part arranged at the lower end of the casing 1 .

Ozone disinfecting principle: Ozone acts on the cell membranes of bacteria and other microorganisms, causing damage to their cell membranes, metabolic disorders, and growth inhibition. When ozone breaks through the cell membrane and continues to permeate, the lipoprotein and lipopolysaccharide in the membrane are destroyed, the cell permeability is changed, and the body is killed. Ozone kills the virus because the oxidation directly destroys its genetic material (RNA/DNA), thereby killing the virus.

Plasma and ozone can both play a role in sterilization and disinfection, but the effect of ozone on the surface of objects in the ambulance medical cabin is more obvious. Therefore, when the ambulance is on standby, the ozone generator of this example disinfection machine can be used for disinfection. After 30 minutes of continuous disinfection by the ozone generator, the air and the surface of the object can be fully disinfected. In order to avoid the harm of ozone to medical staff, the ozone is basically completely attenuated after 30 minutes of shutdown. At this time, the medical cabin can be used.

The power supply unit of this example includes a switching power supply 4 and a battery 5 as a backup power supply directly to the plasma generator, ozone generator, control device and blower fan. Power supply for the switching power supply 4, and an inverter module is arranged between the battery 5 and the switching power supply 4, so that the 220V alternating current is provided by the battery 5 to supply power to the ozone generator. That is, the switching power supply 4 of this example can be powered by a battery 5 , or can be powered by an external power supply socket 6 , and the battery 5 can be a dry battery or a storage battery.

Preferably, the voltage of the battery 5 is 48V, and a charging module for charging the battery 5 is arranged in the housing 1 .

In this example, the switching power supply 4 can output nanosecond narrow pulse high-voltage pulses to drive the plasma generator to work, and can also output high-voltage AC pulses to drive the ozone generator to work.

In this example, a TVOC sensor array module and a PM2.5 sensor respectively connected to the display screen 7 are arranged in the airflow channel.

A temperature sensor and a humidity sensor respectively connected to the display screen 7 are arranged in the casing 1 of this example.

The above sensors display the measured TVOC, PM2.5, temperature and humidity parameters through the display screen 7 .

The display screen 7 can also be used to display the power level of the battery 5 , and in this example, a second display screen 9 for displaying the power level of the battery 5 is provided on the casing 1 .
