The invention discloses a soda water machine with a concentrated juice powder spraying device and belongs to technology of beverage preparation equipment. The soda water machine comprises a main body, a pressure water bottle and the concentrated juice powder spraying device, an air injection port and a base are arranged on the main body, an air injection pipe and a depressurization pipe are arranged on the air injection port, a partition and a venting pipe are arranged in the pressure water bottle, the venting pipe penetrates the center of the partition and is matched with the air injection pipe, the venting pipe and the partition are connected in a sealed manner, a through hole is arranged on the partition, a plunger is further arranged in the pressure water bottle, a lifting mechanism is arranged on the base, a connecting column is arranged on the lifting mechanism, and two sprayers are arranged on the concentrated juice powder spraying device. Compared with the prior art, the soda water machine has the advantages that soda water higher in carbon dioxide concentration can be prepared, concentration of carbo dioxide in the soda water is enabled to be close to be saturated, and taste is pure; during preparation of the soda water, concentrated juice powder is released in the soda water by the two sprayers of the spraying device, so that area of the concentrated juice powder and the soda water is increased, and the soda water is enabled to be uniform in taste.
