[0061] Tap water, river water or well water is added into the spray pot type hydrogen peroxide disinfection and sterilization device as an electrolyte, and air is introduced into the cathode region 130 through the portable micro air pump 1201, and the portable micro air pump 1201 switch is turned on by the power controller 4 to control the flow rate, so that the portable micro air pump 1201 transmits air from the air inlet to the lower side of the cathode 1101, and finally the electrolytic cell is started by the power controller 4 and the electrolysis current and the electrolysis time are set, and the spray pot type hydrogen peroxide disinfection and sterilization device starts to work, and the electrolytic cell automatically stops working after the electrolysis time is reached, that is, the hydrogen peroxide disinfectant has been generated inside the handheld hydrogen peroxide disinfection and sterilization device, and the spray pot type hydrogen peroxide disinfection and sterilization device is also provided with a handle 250 on the upper side of the spray pot type hydrogen peroxide disinfection and sterilization device, and the handle 250 on the upper side of the device is pressed, and the hydrogen peroxide disinfectant generated by the handheld hydrogen peroxide disinfection and sterilization device is atomized by the guide tube 230 through the atomizer 220, and then diffused to the outside through the nozzle 210, thereby achieving the effect of disinfection and sterilization.

[0062] The water outlet of the closed container is sampled for sterilization experiment. The laboratory sterilization effect test method of disinfectant is based on GB / T38502-2020. Gram-negative Escherichia coli (E. coil) and Gram-positive Staphylococcus aureus (S. aureus) are used to evaluate the sterilization effect of hydrogen peroxide produced by the cathode of the electrolytic cell in the utility model.

[0063] Experimental procedure: 100 μl of solution was added to a 48-well plate, followed by 200 μl of bacterial suspension (10 4 CFU / mL) of sterile phosphate buffer. They were then incubated in a thermostat at 37°C for 6 hours, and a bacterial culture medium without solution was used as a control. The above co-culture was transferred to 100 μL of solid agar medium and incubated at 37°C for 16-24 hours, and the colony-forming units on the agar plate were counted, photographed, and recorded. Each group of experiments was repeated three times.

[0064] Figure 2 This is a schematic diagram of the sterilization effect of hydrogen peroxide prepared by the handheld hydrogen peroxide disinfection and sterilization device of the utility model. Figure 2 As shown, it can be seen that after adding the hydrogen peroxide disinfectant generated in situ by the handheld hydrogen peroxide disinfection and sterilization device, 99.99% of the bacteria are killed, which can meet the needs of sterilization and disinfection.

[0065] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.

[0066] Calculated from the electrolysis cost and the materials used, the raw materials used are tap water, river water or well water, the anode used is a stainless steel mesh, and the cathode is a carbon-based material containing nitrogen functional groups, a carbon-based material containing oxygen functional groups, a carbon-based material doped with boron or a carbon-based material doped with phosphorus. The materials are cheap and easy to obtain. The spacing between each electrode sheet in the anode and cathode is 1 cm, and the current density is 1 mA / cm 2 When the distance between the cathode and anode is shortened and the number of electrodes is increased, the electrolysis cost can be further reduced. Therefore, it can be seen that the hydrogen peroxide disinfection and sterilization device proposed by the utility model has a relatively simple equipment construction, low power consumption cost, strong stability, good disinfection and sterilization effect, and is feasible for application in offices, hotels, homes, restaurants and other places.
