[0024] 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.

[0025] like Figures 1 to 6 As shown in the figure, this utility model provides a direct-drive smoothie machine. The direct-drive smoothie machine includes a smoothie machine body 1 and a material tank 11 detachably installed on the smoothie machine body 1. The material tank 11 is provided with a stirring chamber. The stirring chamber is provided with a driving device. The driving device includes a refrigeration tank 3 disposed in the stirring chamber, a drive motor 2 disposed in the smoothie 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 circumference of the refrigeration tank 3. The other end of the rotating shaft 4 is an installation end 42 directly connected to the output shaft 21 of the drive motor 2. Through its simple structural design, 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 in size, more efficient, and cost-effective.

[0026] Furthermore, in this design, the smoothie machine body 1 is provided with a rear shell 12, which has a mounting cavity 120 with an opening facing the rear. The front side of the rear shell 12 extends into the mixing chamber. The material bucket 11 is detachably and sealed on the rear shell 12, and the drive motor 2 is installed inside the mounting cavity 120. Its structure is simple and easy to install.

[0027] Specifically, 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] In addition, since this solution eliminates the traditional gearbox structure, the drive motor can be directly connected to the body 1 of the smoothie machine for easy fixed installation. Preferably, considering the miniaturization of the drive motor, this solution more suitablely adopts the drive motor 2 fixed to the body 1 of the smoothie machine through the positioning mounting plate 8.

[0036] Specifically, the positioning mounting plate 8 has a notch 81 through which the output shaft 21 of the drive motor 2 can pass. A positioning part 82 for positioning and mounting the drive motor 2 is located around the notch 81 on the positioning mounting plate 8. Fixed side wings 83 are also provided on both sides of the positioning mounting plate 8 for positioning and mounting with the smoothie machine body 1. The positioning mounting plate 8 serves as a connector, used for positioning and mounting the drive motor 2 and fixing it within the machine body. This allows for pre-assembly of related components on the positioning mounting plate 8 during production and assembly, followed by modular direct installation into the machine body, achieving efficient assembly.

[0037] To ensure greater stability of the positioning mounting plate 8 during operation of the drive motor 2, a second mounting portion 84 is provided on the positioning mounting plate 8 outside the positioning portion 82. This second mounting portion 84 is located at least near the upper and lower sides of the positioning mounting plate 8. This arrangement provides connection points near the outer contour of the positioning mounting plate 8, allowing it to be fixed to the smoothie machine body 1 using screws, achieving a stable connection and effectively reducing the vibration effects generated by the drive motor 2 during operation.

[0038] This utility model provides a direct-drive smoothie machine, which, through a simple structural 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 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 in size, more efficient, and cost-effective.
