PURPOSE: A gas mixer is provided to naturally promote a mixing operation by expanding the gas distributed from a gas nozzle outlet to the circumference and to stably mix the gas in a wide range by increasing an operating range about the number of rotation in a blower. CONSTITUTION: A gas mixer comprises a mixer body (100), a gas nozzle (200), an orifice (300), and a mixer head (400). The gas flowing through a gas inlet hole passes through the gas nozzle, and the gas nozzle is settled in a lower center of the mixer body. The orifice is connected to be slid on the upper end of the mixer body, and a control unit which is inserted into the gas nozzle is formed. The mixer head is connected to an upper side of the orifice. A flowing range of the air and the gas through an air inlet hole (121) and the gas nozzle is controlled according to a transfer of the mixer body. |
