Hydrogen generator with self-disinfection function

The invention relates to a hydrogen generator with a self-disinfection function. The hydrogen generator comprises an electrolysis module, a hydrogen water cup, an integrated flow channel device and an automatic diversion device, the electrolysis module is used for electrolyzing electrolyzed water to generate hydrogen-containing gas. The hydrogen water cup is used for containing liquid, and the hydrogen water cup is used for injecting hydrogen-containing gas into the liquid to form hydrogen-containing liquid. The integrated flow channel device is stacked above the electrolysis module and comprises a gas inlet flow channel, a gas outlet flow channel and a gas communication flow channel. The automatic diversion device is selectively communicated with the gas inlet channel, the hydrogen water cup and the gas outlet channel or selectively communicated with the gas inlet channel, the gas communication channel and the gas outlet channel. Wherein the pH value of electrolyzed water in the electrolysis module is 12-14.
