The utility model discloses a gas mixing ware. Blender style pipeline structure as an organic whole, pipeline one end is for deriving the mouth, and the other end sets up at least two introducing port, and introducing port department sets up the glass piston, between introducing port and derivation mouth, inside gas distribution board more than the two, the formation gas mixing chamber between two liang of gas distribution boards of setting gradually of pipeline cavity. The not high problem of mixing efficiency can effectually be solved to this device, gives vent to anger stably, and does not receive the influence of target gas molecule volume.
