[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 , 2As shown in Figures 3 and 4, the utility model provides a technical solution: a large-capacity ice cream machine with air-cooled internal circulation, comprising: a chassis shell 1; an evaporator 6 is fixedly installed inside the chassis shell 1, two extrusion tubes are installed inside the evaporator 6, the refrigerant pipeline of the evaporator 6 is wound around the outside of the extrusion tube, and an extrusion screw 4 is rotatably arranged inside the extrusion tube; an air-cooled circulation mechanism is placed in the middle of the evaporator 6, and the air-cooled circulation mechanism includes a heat dissipation fan 8 for cold air circulation; a power unit is placed below the evaporator 6, and is used to drive the extrusion screw 4 to work.

[0023] It should be noted that the utility model places the mixed material in the mixing box 2 for mixing and stirring. When the ice cream needs to be extruded, the corresponding control switch is driven through the discharge valve 11, and the controller controls the power unit to drive the extrusion screw 4 to rotate. The extrusion screw 4 drives the mixed material to move from one end of the extrusion tube to the other end. During this period, the pipeline inside the evaporator 6 cools the extrusion tube, so that the internal material becomes smoothie and is extruded from the discharge valve 11. The cooling fan 8 drives the low-temperature metal guide rod 9 to blow out cold air to cool the interior. The heated hot air is dissipated through the heat dissipation port. The air-cooled internal circulation mechanism utilizes the cold air generated by the evaporator and blows it to the internal components through the fan, which can effectively reduce the internal temperature, help avoid overheating of the components, and improve their working efficiency and life. The temperature reduction of the internal components of the ice cream machine can help maintain a stable working temperature inside the machine. The air-cooled internal circulation mechanism effectively reduces the temperature of the components, provides additional protection, and reduces the risk of damage caused by high temperature.

[0024] See also Figure 1 , 2 As shown, two mixing boxes 2 are arranged on the top of the chassis shell 1, a sealing cover is arranged on the top of the mixing box 2, a stirrer is arranged in the middle of the sealing cover, and the bottom of the mixing box 2 is connected to the extrusion tube through the feeding pipe 12.

[0025] It should be noted that the two mixing boxes 2 of the utility model are used to increase the capacity. The mixing box 2 is a loading container arranged on the top of the chassis shell 1, which is used to store and mix raw materials. The material in the mixing box 2 can be transmitted to the extrusion tube through the feed pipe 12. A sealing cover is provided on the top of the mixing box 2, and its purpose is to close the mixing box 2 and prevent the material from leaking. An agitator is provided in the middle of the sealing cover, which is used to stir the material in the mixing box 2. The rotating motion of the agitator can mix the raw materials or components evenly and prevent the raw materials from precipitating, so as to ensure product quality and consistency.

[0026] See also Figure 1 , 3 As shown, a discharge valve 11 is provided on the outer side of the chassis shell 1 , and the extrusion tube is connected to the discharge valve 11 .

[0027] It should be noted that the pipeline inside the evaporator 6 of the utility model cools the extrusion tube, so that the internal material is turned into smoothie and extruded from the discharge valve 11.

[0029] It should be noted that during the refrigeration process of the utility model, since the metal guide rod 9 extends into the evaporator 6 and contacts the internal heat exchange tube, part of the cold is transmitted to the metal guide rod 9, so that the metal guide rod 9 is in a low temperature state, and the heat dissipation fan 8 blows air to the metal guide rod 9. Under the action of the metal guide rod 9, the wind becomes cold air, so that the cold air is blown into the chassis shell 1, and the drive motor 13 and the other components inside the chassis shell 1 can be cooled.

[0031] It should be noted that the drive motor 13 of the utility model is a power source in the ice cream machine, which is used to provide driving force, and is used to rotate the extrusion screw 4 to achieve the mixing and extrusion process. The large pulley 3 and the small pulley 5 are a pair of wheels connected by pulley transmission. The large pulley 3 is fixedly connected to the end of the extrusion screw 4, and the small pulley 5 is connected to the output end of the drive motor 13, so that the rotation of the drive motor 13 can be transmitted to the extrusion screw 4, thereby promoting the extrusion of the mixture.
