Further, the controller is matched with PH value detection or electric quantity calculation to automatically determine the end point of electrolysis, so that the generation of inactive sodium hydroxide byproducts is avoided; meanwhile, the user can control the concentration of the effective components in the disinfectant by himself according to the requirement.
Further, the spiral anode and the spiral cathode are respectively connected with a controller, and the controller is connected with an external direct current power supply.
In the invention, a special electrolytic tank structure is adopted, and the design of the anode area of the cylinder effectively separates the anode area from the cathode area, so that gas generated by the cathode and the anode can be led out through a pipeline; the design of the heat-insulating box body can ensure that the low-temperature state of the electrolyte is kept in the electrolytic process, and the occurrence of side reaction of chlorine gas precipitation is reduced;
the invention realizes good isolation of the anode region and the cathode region, and leads out hydrogen generated by the cathode through the pipeline, thereby avoiding side reaction between the hydrogen and anode products and danger possibly caused by hydrogen escaping from the chamber; the chlorine gas possibly generated by the anode is dissolved in the solution again, so that the electrolysis efficiency can be improved, and meanwhile, the redundant chlorine gas is led out of the room through a pipeline, so that the chlorine gas can not cause harm to indoor personnel.
The working principle of the invention is as follows: a proper amount of sodium chloride solution (salt solution) with proper concentration is added into an electrolytic bath, an anode area and a cathode area of a generator are formed by virtue of cylindrical cathode design and corresponding liquid sealing action, ice blocks are added into the electrolyte, and the low temperature of the electrolyte is maintained by virtue of a low-temperature protective sleeve. Proper voltage is applied to the anode and the cathode, hydrogen generated on the cathode is led out of a discharge chamber through a pipeline or is used for preparing hydrogen-enriched water, hydroxide ions generated by the cathode are diffused to the anode through a bottom channel and a pore channel of the cylindrical cathode chamber, and react with chlorine under the action of the anode to generate hypochlorite ions so as to generate disinfectant. In order to prevent the possible chlorine formation at the anode from harming personnel, the chlorine formation in the anode compartment can be conducted back to the anode solution (by reacting it with sodium hydroxide) or discharged to the outside of the compartment via a pipe. The user can set the electrolysis time according to the demand of the user, after the electrolysis is finished, the system can automatically cut off the electrolysis power supply, and the sound and light prompt that the disinfectant is manufactured is finished, so that the generation of a large amount of by-product sodium hydroxide is avoided. The spiral anode can reduce the occurrence of side reactions to the maximum extent, and the mesh cathode can ensure that hydrogen can escape smoothly and hydroxide ions can be diffused normally.
The household disinfectant generator of the invention works as follows: adding 2-5 wt% of sodium chloride (salt) solution into an electrolytic cell, adding 3-5 ice blocks, placing in a heat-insulating sleeve, connecting a gas outlet pipeline, starting electrolysis after setting on a controller, and stopping electrolysis automatically after reaching the electrolysis end point. Thus completing the preparation of the disinfectant.

Taking 1000ml of disinfectant as an example, when preparing the disinfectant, firstly adding a sodium chloride solution with the mass percentage concentration of 2.0% into an electrolytic tank, then adding 3-5 small ice blocks, and standing for 10 minutes to reduce the temperature of the electrolyte; the lid was closed and the anode and cathode compartments were checked for good separation and good placement of the anode and cathode in the electrolyte. And a lead-out pipeline for connecting the anode gas and the cathode gas. The desired active ingredient concentration is then selected in the panel in the controller and electrolysis is initiated. The controller adjusts the input electrolysis current to be gradually reduced from 1000mA to 300mA according to the electrolysis process, the electrolysis end point is determined by automatically calculating the electrolysis electric quantity or detecting the PH value or the conductivity by the sensor, the electrolysis is finished, the system automatically cuts off the electrolysis current, and the production is finished by acousto-optic prompt. In this application add the sodium chloride solution (salt solution) of suitable concentration in the electrolysis trough to add a small amount of ice-cubes and maintain the low temperature of system in order to restrain side reaction, with the help of cylindric anode design and liquid seal effect, formed the anode region and the negative pole district of generator, add suitable voltage at anode and negative pole, the hydrogen that produces on the negative pole is drawn out through the pipeline and is discharged outdoor or be used for making hydrogen-rich water, the hydroxyl ion that the negative pole generated diffuses to the anode through the bottom passageway and the section of thick bamboo wall pore of cylinder anode chamber, generate hypochlorite ion with chlorine reaction under the effect of anode. In order to prevent the chlorine gas generated by the anode from harming personnel, the gas generated by the anode chamber is led back to the anode solution or discharged out of the chamber through a pipeline. After the electrolysis is finished, the system can automatically cut off the electrolysis power supply, and the sound and light prompt that the disinfectant is manufactured is finished, so that the generation of a large amount of sodium hydroxide byproducts is avoided.
