[0040] In this utility model, the anti-abrasion pad 6 is preferably made of Tritan material. Tritan is a high-performance plastic with advantages such as high strength, high transparency, high heat resistance, high chemical resistance and impact resistance. It is widely used in the manufacture of food containers, drinking bottles, baby bottles, medical devices and outdoor products. It is a safe, healthy and durable choice. Therefore, the anti-abrasion pad 6 in this utility model is preferably made of Tritan material.

[0041] Specifically, the magnetic drive device includes a motor 8 and a magnetic drive disk 9. The drive shaft of the motor 8 is fixedly connected to the magnetic drive disk 9. The magnetic drive disk 9 is circular to make it more stable during rotation. A mounting part 91 is provided in the middle of the magnetic drive disk 9. The mounting part 91 is provided with one or more magnets, which can be selected according to the actual situation. Semi-circular grooves 92 are symmetrically provided on both sides of the mounting part 91. The thickness of the two semi-circular grooves 92 is the same. The semi-circular grooves 92 ensure that the thickness of the magnetic drive disk 9 is uniform, and also facilitate the injection molding of parts.

[0042] Preferably, the base 3 has a plurality of motor fixing parts 31 for fixing the motor 8 at its center. The motor 8 is cylindrical in shape, and the upper part of the motor 8 is chamfered. Each motor fixing part 31 has an arc-shaped groove on the inner side of its top that matches the chamfer of the motor 8, so as to position the motor 8, making the motor 8 more stable and preventing the motor 8 from shaking during operation, thus ensuring the normal operation of the magnetic drive device. In addition, the motor fixing parts 31 can be set separately around the motor 8 or integrally formed with the base 3.

[0043] Preferably, a battery 10, a circuit board 11, and a charging port 12 are also provided inside the base 3. The circuit board 11 and the motor 8 are all electrically connected to the battery 10. A button hole is provided on the bottom side of the outer cup body 22. A switch button 13 corresponding to the button hole is provided on the base 3. A ring support part 32 protrudes circumferentially from the bottom edge of the side wall of the base 3 and connects to the bottom of the switch button 13. After the switch button 13 on the base 3 is engaged in the button hole on the outer cup body 22, the bottom of the cup body 2 contacts the ring support part 32, thereby supporting and fixing the cup body 2. The switch button 13 is pressed by a spring 14 to control the connection or disconnection of the circuit, thereby turning the stirring cup on and off.

[0044] Preferably, the outer wall of the base 3 is provided with an annular groove above the switch button 13, and a sealing ring 15 is provided in the annular groove to ensure good sealing between the base 3 and the cup body 2 while improving the stability of the connection between the base 3 and the cup body 2.

[0045] Preferably, a cover plate 16 is provided between the bottom of the inner cup body 21 and the base 3. A fixing part 161 is provided with the edge of the cover plate 16 downward. The diameter of the part of the base 3 located above the annular groove gradually decreases from bottom to top, and the minimum diameter is smaller than the diameter of the fixing part 161, while the maximum diameter is larger than the diameter of the fixing part 161. Therefore, during the process of installing the base 3 from the bottom of the cup body 2 into the cavity 212, the top of the base 3 is initially located in the fixing part 161. Since the diameter of the top of the base 3 increases from small to large, and the minimum diameter is smaller than the diameter of the fixing part 161, while the maximum diameter is larger than the diameter of the fixing part 161, when a small part of the top of the base 3 is located in the fixing part 161, the base 3 can be snapped into the fixing part 161. By snapping the top of the base 3 into the fixing part 161 of the cover plate 16, the bottom of the cup body 2 contacts the annular support part 32 on the base 3, realizing the detachable connection between the base 3 and the cup body 2.

[0046] Preferably, the cup lid 1 is provided with a flip-up buckle 17, and the lower side of the cup lid 1 is provided with a sealing connection structure that matches the cup body 2, the sealing connection structure including a sealing rubber ring.

[0047] Specifically, the cup lid 1 covers the top opening of the cup body 2. The cup lid 1 has a drinking spout located near the edge of the top of the cup lid 1. The top surface of the cup lid 1 also has a flip-up buckle 17 with a silicone stopper. The silicone stopper corresponds to the drinking spout. When the buckle 17 is closed on the cup lid 1, the silicone stopper covers the drinking spout. The lower surface of the buckle 17 has a cylindrical silicone stopper. The top of the cup lid 1 has a through hole corresponding to the cylindrical silicone stopper. When the cup lid 1 is closed, the cylindrical silicone stopper is inserted into the through hole of the cup lid 1, thereby achieving a sealing effect.

[0048] Preferably, the bottom of the base 3 is provided with a silicone pad 18. Specifically, the silicone pad 18 is provided with a charging port plug that is compatible with the charging port 12. The silicone pad 18 has good waterproof and anti-slip properties, which effectively prevents the mixing cup from sliding due to friction during use, thereby increasing the stability and safety of the mixing cup.
