[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1 to 4 As shown, this utility model provides a driving device for a cold drink making machine, including a refrigeration tank 3 disposed in the stirring chamber of the cold drink machine body, a drive motor 2 disposed in the cold drink machine body 1, and a rotating shaft 4. The rotating shaft 4 is rotatably inserted into the refrigeration tank 3, and the front end of the rotating shaft 4 is an output connection end 41 extending from the front end of the refrigeration tank 3. The output connection end 41 is used to install a stirring component and drive the stirring component to rotate around the outer periphery of the refrigeration tank 3. During operation, the refrigeration tank 3 is used to install a condensation system, which lowers the temperature of the refrigeration tank 3 itself. The outer periphery of the refrigeration tank 3 is the stirring chamber. The material is cooled by contacting the outer periphery of the refrigeration tank 3, reaching the temperature of a cold drink. The rotating shaft 4 is connected to the stirring blades through the output connection end 41 of the refrigeration tank 3, driving the stirring blades to rotate, thereby preventing the material from accumulating and condensing on the refrigeration tank 3. Through a simple structural design, this design ensures that the rotating shaft can rotate stably relative to the refrigeration tank, thereby driving the stirring blades on its output connection end to rotate and complete the stirring operation. Furthermore, the other end of the rotating shaft 4 in this design is a mounting end 42 directly connected to the output shaft 21 of the drive motor 2. The direct connection of the rotating shaft's mounting end to the drive motor's output shaft eliminates the need for a traditional gearbox, resulting in a simpler structure, smaller size, higher efficiency, and cost savings.
[0025] The drive motor 2 described in this solution is preferably a DC drive motor. DC motors have the advantage of high efficiency, with an efficiency of over 90% in converting electrical energy into mechanical energy. This is because the electromagnet coil of a DC motor only needs to be excited once to maintain magnetic flux, unlike AC motors which frequently reverse the magnetic flux, thus consuming less energy. Furthermore, DC motors offer higher control precision, achieving accurate speed control by adjusting current and voltage. In addition, DC motors can achieve more precise position control through feedback control systems. This makes DC motors widely used in industrial automation, robotics, and other fields. Moreover, compared to other types of motors, DC motors have lower noise levels. This is because the friction between the rotor and stator of a DC motor is relatively small, and the control system of a DC motor can reduce motor noise through PWM modulation.
[0026] Furthermore, DC motors are relatively simple to control; speed control can be achieved by adjusting current and voltage. In addition, DC motors can achieve more precise position control through a feedback control system. Therefore, this solution uses a DC drive motor directly connected to the rotating shaft, resulting in more precise control, more convenient speed adjustment, a wider speed range, and the ability to determine the smoothie's (ice cream's forming state) through torque changes.
[0027] Specifically, in this design, the mounting end 42 is sleeved with the output shaft 21, and the output shaft 21 is also provided with a radially mounted limiting pin. After sleeved, the connection between the mounting end 42 and the output shaft 21 is more stable through the insertion of the limiting pin, facilitating synchronous rotation.
[0028] Furthermore, preferably, the output shaft 21 is provided with a positioning hole for the mounting end 42 to be inserted. The positioning hole has a polygonal cross-section, and the mounting end 42 has a mounting portion whose outer contour matches the cross-section of the positioning hole. The polygonal positioning hole and the matching mounting portion achieve alignment and rotational transmission connection, and the aforementioned limiting pin further achieves axial locking, facilitating synchronous rotation and resulting in higher feedback accuracy.
[0029] In this embodiment of the invention, to further improve the stable rotation of the rotating shaft, a rotating connector 5 is provided at the front end of the refrigeration tank 3. The output connection end 41 of the rotating shaft 4 passes through the rotating connector 5 and extends to the front side of the refrigeration tank 3. Its structure is simple and easy to assemble.
[0030] Specifically, the rotating connector 5 has the following structure: It includes a front cover 51 and an inner seat 52. The front end of the refrigeration tank 3 has an installation opening. The inner seat 52 is located inside the refrigeration tank 3. The front cover 51 covers the front side of the installation opening and is connected to the inner seat 52. Both the front cover 51 and the inner seat 52 have through holes for the rotating shaft 4 to pass through. Furthermore, the front cover 51 has a rearwardly extending positioning connection part 510, and the inner seat 52 has a groove for the positioning connection part 510 to be inserted and installed. Its structure is simple, easy to install, and ensures stable rotation of the rotating shaft.
[0031] In addition, the rotating connector 5 not only makes the rotating shaft more stable to install, but also ensures a sealing effect. A first sealing element 61 is provided between the front cover 51 and the rotating shaft 4, and a second sealing element 62 is provided between the front cover 51 and the refrigeration tank 3. This ensures that the gaps between the rotating shaft 4 and the front cover 51, and between the front cover 51 and the refrigeration tank 3, are filled by the first sealing element 61 and the second sealing element 62, so as to better ensure the dry environment inside the refrigeration tank 3 and prevent materials from remaining in the gaps or entering the interior and causing damage.
[0032] In this design, for ease of installation, the output connection end 41 of the rotating shaft 4 has a polygonal cross-section. This facilitates its installation with the stirring blades, enabling the stirring blades to rotate.
[0033] This utility model also provides a smoothie machine, which is equipped with the aforementioned drive device, and thus the smoothie machine also has the same beneficial effects.
[0034] This utility model also provides an ice cream machine with the aforementioned driving device, thus the ice cream machine also has the same beneficial effects.
[0035] This utility model provides a drive device for a cold drink making machine. Through a simple structural design, it ensures that the rotating shaft can rotate stably relative to the refrigeration tank, thereby driving the stirring blades on its output connection end to rotate and complete the stirring drive work. Moreover, the mounting end of the rotating shaft in this solution is directly connected to the output shaft of the drive motor, eliminating the need for a traditional gearbox, thus making the structure simpler, smaller, more efficient, and cost-effective.

These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.
