Safe and reliable hydrogen production device

The utility model discloses a safe and reliable hydrogen production device which comprises a hydrogen production machine main body, when the hydrogen production machine is used for producing hydrogen, firstly, constant current and constant voltage are provided for a hydrogen generator through an input unit for electrolyzing water to obtain hydrogen, and the hydrogen is stored in the water from a porous nozzle through a pressure pipe connected with a hydrogen outlet; the liquid level sensor detects water used for electrolysis in the storage unit at any time and displays the water on the display unit, the temperature sensor senses the temperature in the hydrogen generator at any time, and if the water level is lower than the standard water level and is insufficient for electrolysis, or the temperature in the hydrogen generator is equal to or higher than the specific temperature, the hydrogen generator is started. The control unit can control and cut off the constant current provided by the input unit, the hydro
