Oxy-hydrogen breathing machine

The invention relates to an oxy-hydrogen breathing machine, which has the advantage that: hydrogen can be completely inhaled by a human body without being leaked in air, so that people can safely breathe oxygen and hydrogen. An eletrolysis water hydrogen oxygen device is connected with a filter cup through a connecting pipe; the filter cup is connected with a temporary storage bag and a pressure limiting cup; a filter cup air inlet, a filter cup air outlet and a temporary storage outlet are arranged on the filter cup; a pressure limiting cup air inlet and a pressure limiting cup air outlet are designed on the pressure limiting cup; the eletrolysis water hydrogen oxygen device is connected with the filter cup air inlet through a connecting pipe; the lower end of the filter cup air inlet is connected with a medical hard tube; the temporary storage outlet of the filter cup is in seal connection with the temporary storage bag; the filter cup air outlet of the filter cup is connected with the pressure limiting cup
