DETAILED DESCRIPTION

[0027] like Figures 1 to 9As shown, a positioning device for a stirring rod of the utility model comprises a cup body 1, a magnetic driver 2 and a stirring rod 3, wherein the cup body 1 serves as a container for containing liquid; the magnetic driver 2 serves as a driving source for driving the stirring rod 3 to rotate; and the stirring rod 3 serves as a stirring component for stirring the liquid in the cup body 1. The magnetic driver 2 is arranged below the cup body 1, and the stirring rod 3 is arranged in the cup body 1, and the magnetic driver 2 is magnetically connected to the stirring rod 3. Specifically, the cup body 1 is provided with a positioning portion 4, and the stirring rod 3 is arranged on the positioning portion 4. Through the above arrangement, the stirring rod 3 can be positioned to prevent the stirring rod 3 from deviating from the center position due to uneven power strength or non-centered and symmetrical magnetic field attraction, thereby improving the stirring effect, and the positioning portion 4 can prevent the stirring rod 3 from hitting the bottom surface of the cup body 1 due to imbalance during rotation, thereby reducing the wear of the cup body 1.

[0028] like Figures 2 to 5 As an implementation method, the positioning portion 4 includes a positioning groove 5, the stirring rod 3 is arranged on the positioning groove 5, the stirring rod 3 is provided with a convex rib 6, and the convex rib 6 is arranged on the positioning groove 5. Through the above arrangement, the stirring rod 3 can be positioned to avoid the stirring rod 3 from deviating from the positioning groove 5. In addition to the positioning groove 5, the positioning portion 4 can also be in the form of a positioning column. When the positioning column is used, the stirring rod 3 can be provided with a groove matching the positioning column, so that the stirring rod 3 rotates with the positioning column as the rotation center to avoid deviation.

[0029] Specifically, the height from the outer edge 12 of the positioning groove to the center 13 of the positioning groove gradually decreases. As the height from the outer edge 12 of the positioning groove to the center 13 of the positioning groove gradually decreases, the groove wall of the positioning groove 5 supports the convex rib, and in particular, the stirring rod 3 in rotation is subjected to the centripetal force to prevent the stirring rod 3 from leaving the positioning groove 5, thereby constraining the stirring rod 3 during its rotation and preventing it from leaving the positioning groove 5.

[0030] The cross-sectional shape of the positioning groove 5 is linear or arc-shaped. The cross-sectional shape of the positioning groove 5 is a section made along the center line of the positioning groove. When the cross-sectional shape of the positioning groove 5 is linear, the cross-sectional shape is formed by connecting a plurality of straight lines with different inclination angles. The positioning groove 5 as a whole is generally conical or a combination of a conical and a truncated cone. When the cross-sectional shape of the positioning groove 5 is arc-shaped, the positioning groove 5 as a whole is generally spherical.

[0031] In this embodiment, the positioning groove 5 is a spherical cavity. Through the above arrangement, the transition from the outer edge 12 of the positioning groove to the center 13 of the positioning groove can be natural and smooth. When the stirring rod 3 deviates from the center 13 of the positioning groove, it can return to the center 13 of the positioning groove under the joint action of the spherical cavity, gravity and the magnetic drive 2, and the positioning effect is good.

[0032] When both ends of the stirring rod 3 are in contact with the outer edge 12 of the positioning groove and the stirring rod 3 is in a horizontal state, the height difference between the contact point of the stirring rod 3 with the outer edge 12 of the positioning groove and the lowest point of the rib 6 is defined as the height of the rib 6. The height of the rib 6 is defined as H1, and the depth of the positioning groove 5 is defined as H2.

[0033] As an implementation method, the height H1 of the convex rib 6 is less than or equal to the depth H2 of the positioning groove 5. Through the above arrangement, the two ends of the stirring rod 3 contact the outer edge 12 of the positioning groove, and the magnetic driver 2 arranged at the lower end of the cup body 1 has a downward magnetic attraction pulling force relative to the stirring rod 3. When the magnetic driver 2 drives the stirring rod 3 to rotate, the two ends of the stirring rod 3 rotate along the outer edge 12 of the positioning groove. If the stirring rod 3 deviates to the outside of the positioning groove 5, due to the downward magnetic attraction pulling force and the convex rib 6 of the stirring rod 3 rotating under the effect of the curved surface resistance of the positioning groove 5, the stirring rod 3 is limited to rotate in the positioning groove 5 without deviating and losing the stirring function.

[0034] As another implementation method, the height H1 of the rib 6 is greater than the depth H2 of the positioning groove 5. Through the above arrangement, the rib 6 in the middle of the stirring rod 3 contacts the center 13 of the positioning groove, and the two ends of the stirring rod 3 do not contact the outer edge 12 of the positioning groove when the stirring rod 3 is in an active state. When the stirring rod 3 is in a stationary state, one end contacts the outer edge 12 of the positioning groove, and the other end is suspended and does not contact the outer edge 12 of the positioning groove. The magnetic driver 2 arranged at the lower end of the cup body 1 has a downward magnetic attraction force relative to the stirring rod 3. When the magnetic driver 2 drives the stirring rod 3 to rotate, if the stirring rod 3 deviates in the direction of the high edge of the boss, due to the effect of the downward magnetic attraction force and the effect of the resistance of the curved surface of the positioning groove 5 on the rib 6 of the stirring rod 3, the stirring rod 3 is limited to rotate on the boss and will not deviate and lose the stirring function.

[0035] As an implementation method, a boss 7 is provided at the bottom of the cup body 1, and the positioning groove 5 is provided on the boss 7. Through the above arrangement, the positioning groove 5 can be made higher than the bottom surface of the cup body 1, effectively preventing the stirring rod 3 from colliding with the bottom surface of the cup body 1 during rotation and causing the bottom surface of the cup body 1 to be worn. At the same time, by providing the positioning groove 5 on the boss 7, the bottom of the positioning groove 5 can be made not lower than the bottom of the cup body 1, reducing the height of the entire stirring cup, making the overall structure of the stirring cup more compact, and saving material costs.

[0036] Specifically, the boss 7 is integrally formed with the positioning groove 5. Through the above arrangement, the sealing effect of the cup body 1 can be improved, and the whole is integrally formed by stamping, which is convenient for production and manufacturing, and can also improve the strength of the bottom of the cup body 1, so that the bottom of the cup body 1 is not easily deformed.

[0037] like Figure 6 to Figure 7As shown, as an implementation method, the cup body 1 is provided with a connecting sleeve 8, the connecting sleeve 8 is provided with a fixing groove 9, and the magnetic driver 2 is arranged in the fixing groove 9. Through the above arrangement, it is easy to fix the magnetic driver 2. Specifically, the connecting sleeve 8 is provided with a positioning protrusion 10, the cup body 1 is provided with a positioning groove 11, and the positioning protrusion 10 is arranged in the positioning groove 11. Through the above arrangement, it is easy to position and connect the connecting sleeve 8 and the cup body 1, and it is convenient to disassemble and assemble the two.

[0038] The utility model provides a positioning portion 4 on the cup body 1, and the stirring rod 3 is provided on the positioning portion 4, so that the stirring rod 3 will not deviate under the action of the positioning portion 4, thereby improving the stirring effect of the stirring rod 3. At the same time, the setting of the positioning portion 4 can also prevent one end of the stirring rod 3 from hitting the bottom surface of the cup body 1 when rotating, thereby avoiding wear of the bottom surface of the cup body 1 and improving the overall aesthetics of the bottom surface of the cup body 1.

[0039] The above are only specific embodiments of the utility model, but the technical features of the utility model are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the utility model to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the utility model.
