In order to solve the problem of residual traditional disinfectant, a hypochlorous acid disinfectant is provided on the market, and weakly acidic hypochlorous acid water is a well-known safe and efficient disinfectant, and the hypochlorous acid is inorganic micromolecules which can penetrate cell walls and cell membranes of microorganisms to destroy life substances such as proteins and nucleic acids of the microorganisms, so that the microorganisms die; hypochlorous acid acts only on organic substances such as bacteria and viruses, and is decomposed by taurine on the cell surface of human or animal cells, so that it does not affect enzymes of the cells, and thus is harmless to human or animal. The hypochlorous acid disinfectant can kill not only coronavirus, but also general bacteria, yeast-like fungi, bacillus viruses and spore viruses (for spore viruses, even medical iodine tincture and alcohol cannot be killed). The hypochlorous acid disinfectant can be used in various occasions such as medical health institutions, various public places, food processing, restaurants, families and the like; can disinfect various objects, including endoscopes, surgical instruments, sores/wounds, skin mucosa, air, hands, object surfaces and fabrics, fruits and vegetables, tableware, secondary water supply equipment facilities, and the like.

In this design, the saline water of NaCl is placed in bottle 1, and hypochlorous acid water manufacture appearance uses that the concentration of saline water is that 0.3g salt/200 ml water is comparatively suitable, and the hypochlorous acid water of output is that the pH value is between 2.5-6.5, and hypochlorous acid concentration is about 2ppm, can be applicable to the hypochlorous acid sterilizing water on human surface, because the difference of each place quality of water, needs the adjustment to add the weight of salt.
Next, as will be explained in conjunction with fig. 2 and 3, the core of this design is if hypochlorous acid water is produced by brine.
As shown in fig. 2 and 3, the base inner cylinder 2 is circular and through, the cross section of the base inner cylinder is like an H-shaped, a baffle plate for blocking is arranged in the middle of the base inner cylinder 2, and the base inner cylinder 2 is divided into an upper layer and a lower layer; the electrolytic box 3 is arranged on the upper layer; a power supply 21 and a reverse pole control board 22 are arranged on the lower layer, and the power supply 21 is a lithium battery; the reverse control board 22 is a PCB board, and the PCB board can also control the on/off of the light and the power supply 21.
The polarity inverting control board 22 is provided with a polarity inverting function (i.e. the cathode and the anode of the electrolytic sheet are inverted), the cathode after polarity inverting becomes the anode, so that the metal ions adsorbed on the original cathode can be well removed, and simultaneously the acidic solution generated on the current anode of the original cathode after polarity inverting is fully neutralized with the alkaline solution originally accumulated in the cathode electrolytic cell, so as to achieve the functions of cleaning the electrolytic sheet and neutralizing the electrolyte, therefore, the hypochlorous water manufacturing instrument of the invention does not need a channel for specially discharging the alkaline liquid. The reverse electrode cleaning has two functions of manual operation and automatic operation, and when the pH value of the spray liquid is increased due to excessive accumulation of the alkaline liquid in the cathode electrolytic cell and the sterilization effect is influenced, the reverse electrode cleaning function can be started at any time; the automatic cleaning is to automatically start the reversed electrode cleaning function after the electrolysis degree of the general water quality is calculated and set to a certain electrolysis frequency; the bottom of the lower layer can be fixed with a bottom plate through screws.

The positive electrode plate 33 and the negative electrode plate 34 are fastened to the reverse control plate 22 by titanium screws serving as lead wires, and the titanium screws also serve as guides.
The working principle of the electrolytic cell 3 is as follows: when the brine in the bottle body 1 is electrolyzed, the cathode electrolytic sheet concentrates sodium ions and hydrogen ions, and the sodium ions are largely isolated in the electrolytic cartridge 3 due to the isolation of the anion exchange membrane 32 (AEM), and then the hydrogen ions are discharged as hydrogen gas, in a manner which will be further described with reference to fig. 4.
The anion exchange membrane 32 (AEM) has excellent hydrophilicity, is an ion exchange membrane having good electrical conductivity and good permselectivity, allows hydrogen ions (protons) to pass therethrough, conducts protons, and can effectively isolate sodium ions. The method is characterized in that: (black brown) is low in resistivity, excellent in conductivity, low in energy consumption and high in selective transmittance. ② compared with ion exchange resin, the catalyst has good catalytic effect, is not easy to be poisoned and has long service life.

therefore, a large amount of hypochlorous acid water is generated.
Therefore, it can be seen that:
acidic hypochlorous acid water is formed above the anion exchange membrane 32;
below the anion exchange membrane 32, an alkaline solution is formed because the hydroxide ions pass through and combine with the sodium ions.
Through the action of the anion exchange membrane 32 and the electrolysis box 3, two strands of electrolyte substances for acid-base separation are formed, and a large amount of hypochlorous acid water which can be pumped away in the bottle body 1 becomes a good disinfection water agent.
