By starting the air pump 5, the air charging of the cold drink raw materials in the freezing cylinder 3 is realized, so as to improve the taste of the cold finished products. In this solution, since the air pump 5 is located outside the freezing cylinder 3, the cold drink raw materials are prevented from coming into contact with the air pump 5, thereby reducing the cleaning and maintenance work for the staff. In addition, to a certain extent, this solution ensures that the cold drink raw materials are not contaminated, thus guaranteeing the quality of the cold finished products.

[0033] Preferably, the air charging pipe 6 is provided with a one-way valve 60, and the one-way valve 60 is used to prevent air from flowing back.

[0037] In this embodiment, as Figure 2-4As shown, the setting of the first sealing ring 23 can ensure the sealing performance of the first opening 31, preventing the leakage of cold drink raw materials to the outside of the freezing cylinder 3 or the entry of external impurities into the inside of the freezing cylinder 3. The setting of the first mounting bracket 21 plays a role in supporting and fixing the conveying pipe 22, enabling the conveying pipe 22 to be stably installed on the freezing cylinder 3. Further explanation, the setting of the conveying pipe 22 can convey the cold drink raw materials from the feed port 11 to the inside of the freezing cylinder 3.

[0041] When the operating handle 43 swings upward, the stop block 47 can block the second discharging port 410; when the operating handle 43 swings downward, the stop block 47 can move away from the second discharging port 410.

[0042] In this embodiment, as Figure 4-5As shown, since the discharge tray 41 is arranged at the first discharge port 12, the arrangement of the discharge tray 41 can ensure the airtightness of the freezing cylinder 3. In the initial state, the stopper 47 completely blocks the second discharge port 410. When it is necessary to extrude the cold finished product, the staff can swing the operating handle 43 downward, thereby driving the linkage arm 45 to move upward, and at the same time, can apply an upward elastic force to the torsion spring 46, thereby driving the stopper 47 to move upward, so that the stopper 47 moves away from the second discharge port 410. At the same time, the driver 9 is started, and the driver 9 starts the stirrer 7 to stir the cold drink raw materials in the freezing cylinder 3. During the process of the stirrer 7 stirring the cold drink raw materials, the stirrer 7 can push the cold drink raw materials to move toward the second discharge port 410 of the discharge tray 41, so that the finally formed cold finished product can come out of the second discharge port 410.
