Disclosed is a soda maker with an automatic-sealing gas outlet valve (7), comprising a main body (1), a base (2), a top cover (3), a body support (4), a carbon dioxide cylinder (5), a soda bottle (6), an outlet valve (7) provided on the carbon dioxide cylinder (5), and an inlet assembly (8) connected to an opening of the soda bottle (6). The invention further comprises a drive plate (9), a deceleration frame (10), a gas inlet connecting rod (11), a first pressure spring (12), a second pressure spring (13), a third pressure spring (14), a locking fastener (15), and a gas inlet body (81), wherein the gas inlet body internally comprises a pressure-driven device (16) and a switch frame (17). In the soda maker with the automatic-sealing gas outlet valve (7), the drive plate (9) and the gas inlet connecting rod (11) turn and press against a gas outlet valve rod (72) of the gas outlet valve (7), allowing a gas contained within the carbon dioxide cylinder (5) to enter the soda bottle (6) while the locking fastener (15) engages and locks the gas inlet connecting rod (11) at the same time. When a pressure within the soda bottle (6) reaches a preset pressure, the pressure-driven device (16) drives a lower end of the locking fastener (15) to release the locking fastener (15) from a locking position of the gas inlet connecting rod (11), and resets the gas inlet connecting rod (11) to an original position to close the gas inlet valve (7). The soda maker with the automatic-sealing gas outlet valve (7) is safe, reliable, and easy to use.L'invention concerne une machine à boisson gazeuse avec une valve de sortie de gaz à étanchéité automatique (7), comprenant un corps principal (1), une base (2), un couvercle supérieur (3), un support de corps (4), une bouteille de dioxyde de carbone (5), une bouteille de boisson gazeuse (6), une valve de sortie (7) disposée sur la bouteille de dioxyde de carbone (5), et un ensemble entrée (8) relié à une ouverture de la bouteille de boisson gazeuse
