Title: GAS MIXER AND GAS MIXING DEVICE
Abstract:
This gas mixer (100) is provided with a housing (120) and a soundproofing member (160). The housing (120) has: a first inflow hole (110) into which air (101) flows; a second inflow hole (152) into which oxygen (102) flows; and an outflow hole (113) from which a mixed gas (103) flows. The housing (120) has inside a first flow path (111), a second flow path (112), and a third flow path (150). The first flow path (111) connects to the first inflow hole (110). The third flow path (150) connects the first flow path (111) and the second flow path (112). The second inflow hole (152) and the second flow path (112) are provided on the same linear axis (R). The direction in which the third flow path (150) extends is the same as the direction of the linear axis (R). Further, the cross sectional area of the third flow path (150) is smaller than the cross sectional area of the first flow path (111). The cross sectional area of the third flow path (150) is smaller than the cross sectional area of the second flow path (112).
