[0037] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0038] like Figures 1 to 4 The figure shows a mixer according to the present invention, comprising a mixing container 100 and a base 200. The mixing container 100 comprises a mixing portion 11 and a connecting portion 12 disposed at the lower end of the mixing portion 11. A cutting tool 13 is disposed within the mixing portion 11, and the cutting tool 13 is provided with a cutting shaft 14, the lower end of which extends into the connecting portion 12. A rotor assembly 300 is disposed within the connecting portion 12 and is connected to the cutting shaft 14. A stator assembly 400 is disposed within the base 200.

[0039] During actual use, the mixing container 100 is mounted on the base 200, specifically the connecting portion 12. The rotor assembly 300 is then located within the stator assembly 400. When powered on, the stator assembly 400 generates a magnetic field. The magnetic force of this field causes the rotor assembly 300 to rotate, which in turn drives the blade shaft 14 and blade 13 to rotate, cutting and mixing the food within the mixing portion 11.

[0040] The rotor assembly 300 and the stator assembly 400 cooperate to realize transmission, without the use of parts such as couplings, making the mixer structure more compact and the production cost low; at the same time, there is no mechanical connection structure between the mixing container 100 and the machine base 200, and the mixing container 100 and the machine base 200 can be easily separated, making it convenient to clean the mixing container 100 and other operations.

[0041] In addition, the mixing container 100 includes a stirring portion 11 and a connecting portion 12. The stirring portion 11 is used to stir food, and the connecting portion 12 is used to accommodate the rotor assembly 300, forming two independent and separated spaces to ensure food safety; at the same time, the connecting portion 12 prevents the rotor assembly 300 from being exposed, reduces the impact of the external environment on the operation of the rotor assembly 300, plays a role in waterproofing and dustproofing, and improves the service life of the blender.

[0042] Specifically, the rotor assembly 300 includes a rotor core 31 fixed to the outside of the blade shaft 14, and rotor permanent magnets 32 embedded in the outer wall of the rotor core 31. The rotor core 31 is disc-shaped, and the rotor permanent magnets 32 are distributed in a circular array around the outside of the rotor core 31. Correspondingly, the stator assembly 400 includes a ring-shaped stator core 41 and stator windings 42 disposed on the stator core 41. The stator windings 42 are arranged corresponding to the rotor permanent magnets 32. When powered, a magnetic field is generated between the stator windings 42 and the rotor permanent magnets 32. This magnetic force drives the rotor core 31 to rotate, thereby driving the blade shaft 14 to rotate.

[0043] Specifically, a clamping portion 141 extends from the blade shaft 14, and a connecting hole 33 is defined in the rotor assembly 300. The clamping portion 141 cooperates with the connecting hole 33 to achieve synchronous rotation of the blade shaft 14 and the rotor assembly 300. Furthermore, the cross-section of the clamping portion 141 and the connecting hole 33 is polygonal. When the rotor assembly 300 rotates, the blade shaft 14 rotates accordingly. The transmission structure using the clamping portion 141 and the connecting hole 33 is easy to assemble and has high transmission efficiency.

[0044] Specifically, the end of the base 200 facing the mixing vessel 100 is provided with a mounting groove 21, which is designed to mate with the connecting portion 12; the stator assembly 400 is positioned around the mounting groove 21. When the blender is in use, the connecting portion 12 of the mixing vessel 100 is installed in the mounting groove 21. At this point, the rotor assembly 300 is located inside the stator assembly 400. When powered on, the rotor assembly 300 and the stator assembly 400 can transmit power, thereby driving the blade shaft 14 to rotate. The connection portion 12 installed in the mounting groove 21 ensures a more stable connection between the mixing vessel 100 and the base 200, preventing the mixing vessel 100 from separating from the base 200 during operation.

[0045] Specifically, the horizontal cross-sections of the mounting groove 21 and the connecting portion 12 are both circular, and the radius of the horizontal cross-section of the mounting groove 21 is larger than the radius of the horizontal cross-section of the connecting portion 12; the connecting portion 12 is installed in the mounting groove 21, and there is a gap between the outer wall of the connecting portion 12 and the inner wall of the mounting groove 21; the mixer will vibrate when working, and the gap provides a horizontal movement space for the mixing container 100. During vibration, the mixing container 100 can shake within the gap range, play a buffering role, and improve the working stability of the mixer.

[0046] Specifically, a first rotational bearing 121 is fixedly mounted at the center of the bottom inner portion of the connecting portion 12, with the bottom end of the blade shaft 14 rotatably connected to the first rotational bearing 121. A second rotational bearing 122 is fixedly mounted at the center of the top inner portion of the connecting portion 12, with the blade shaft 14 rotatably connected to the inner side of the second rotational bearing 122. The first and second rotational bearings 121, 122 enhance the rotational stability of the blade shaft 14. Furthermore, sealing rings are provided on the first and second rotational bearings 121, 122 to enhance the waterproof and dustproof properties of the connecting portion 12.

[0047] Specifically, the cutter 13 and the cutter shaft 14 are fixedly connected by a fastening bolt 15 to achieve synchronous rotation of the cutter 13 and the cutter shaft 14 .

[0048] Specifically, an opening is provided at the upper end of the stirring portion 11, and a sealing cover 16 is detachably connected to the opening; a handle 17 is provided on the side wall of the stirring portion 11; the sealing cover 16 and the handle 17 can optimize the user experience of the blender.

[0049] Compared with the prior art, the blender involved in the present invention is provided with a mixing container 100 and a machine base 200, wherein a cutter 13 and a cutter shaft 14 are provided in the mixing container 100, and a rotor assembly 300 connected to the cutter shaft 14 is provided; at the same time, a stator assembly 400 is provided in the machine base 200; when powered, a magnetic field is generated, and the stator assembly 400 drives the rotor assembly 300 and the cutter shaft 14 to rotate, thereby achieving the mixing of food. This transmission structure can simplify the transmission mechanism of the blender and reduce production costs; at the same time, there is no mechanical connection structure between the mixing container 100 and the machine base 200, and the mixing container 100 and the machine base 200 can be easily separated, and the mixing container 100 can be cleaned, thereby optimizing the user experience. In addition, the mixing container 100 includes a stirring portion 11 and a connecting portion 12, which divide the stirring space and the transmission structure, thereby increasing the service life of the blender.

[0050] The above merely represents the preferred technical solution of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
