Ultrathin motor driving structure and stirring cup

Abstract

According to the ultrathin motor driving structure and the stirring cup provided by the utility model, the ultrathin motor driving structure rotates through the rotor magnet, and the rotor magnet also can be applied by adopting a two-pole magnet. In the using process, the center of the stirrer is located at the center of the rotor magnet, so that the stirrer rotates around the circle center of the stirrer all the time in the stirring process, and eccentric rotation is avoided. The rotor magnet is directly arranged in the ultrathin motor driving structure, so that the ultrathin motor driving structure is thinner. In the installation process, the penetrating face of the ultrathin motor driving structure is directly attached to the bottom of the stirring cup for installation, alignment or adjustment of the distance between the rotor magnet and the bottom of the stirring cup is not needed, and therefore the assembly efficiency is higher, and the assembly time is shortened. The influence on the production efficiency due to alignment or guarantee of the mounting distance between the rotor magnet and the bottom of the stirring cup is avoided.

Description

Technical Field

[0001] This utility model relates to the technical field of stirring cups, specifically to an ultra-thin motor drive structure and a stirring cup. Background Technology

[0002] Traditional mixing cups use a stirring rod for manual stirring to mix the substances inside, thereby accelerating dissolution or achieving a uniform consistency. However, this method requires manual stirring and is very inefficient.

[0003] The applicant's earlier application (CN220159808U) describes a magnetic stirring cup. By installing a drive motor at the bottom of the stirring cup and a drive magnet at the output end of the drive motor, the rotation of the drive motor drives the drive magnet to rotate, thereby causing the stir bar inside the stirring cup to rotate, so as to stir the substances in the cup and mix them thoroughly, thus avoiding the problem of low efficiency of manual stirring.

[0004] However, by placing the drive magnet outside the drive motor, sufficient space for the drive magnet to rotate must be ensured during installation. Therefore, the drive magnet must maintain a certain distance from the inner wall of the installation space. This results in a very thick bottom of the mixing cup and requires sacrificing some of the internal volume of the mixing cup, which severely limits the usable and installation dimensions.

[0005] At the same time, during installation, it is necessary to ensure the rotation space of the drive magnet to avoid collision between the drive magnet and the inner wall of the rotation space. Therefore, precise assembly is required during the assembly process, resulting in very low installation efficiency.

[0006] The applicant conducted secondary research and development. In the earlier application (CN116865515B Magnetic Output Motor and Magnetic Stirring Container Using the Motor), the rotor magnet was placed in the drive motor and mounted on the rotor, so that the drive motor and the rotor magnet were integrated. This allowed the rotor magnet to be hidden inside the drive motor, reducing the height of the entire drive structure. This reduced the thickness of the installation space at the bottom of the stirring cup and prevented the rotor magnet from being interfered with by the magnetism within the installation space. In addition, during the installation process, the drive motor only needs to be attached to the bottom of the stirring cup to complete the assembly, without the need to reserve a distance between the rotor magnet and the inner wall of the installation space.

[0007] However, the magnetic output motor adopts the driving principle of the brushless motor, and the rotor magnet of the brushless motor is coupled with the stirrer in the stirring cup. The magnetism of the rotor magnet acts on the stator coil of the brushless motor and the stirrer in the stirring cup. Therefore, the rotor magnet of the brushless motor needs at least a 4-pole magnet. However, during the driving process of the 4-pole magnet or more, the stirrer is adsorbed to one side under the influence of the magnetic field of the 4-pole magnet, and the center of the stirrer is not located on the axis of the stirring cup, thereby causing poor stirring effect during stirring.

[0008] Secondly, since the magnetic output motor adopts the driving principle of the brushless motor, during the process of stirring milk tea or coffee, the milk tea powder and coffee particles may exist at the bottom of the stirring cup. During the process of starting the stirrer driven by the brushless driving structure, the phenomenon of stuttering may occur due to insufficient power, thereby affecting the use.

[0009] Meanwhile, during the braking process, since the brushless motor adopts an alternating magnetic field for driving, a reverse current is not enough to stop the rotor magnet suddenly, thereby causing low control accuracy, and the brushless motor cannot be used in some high-precision control fields.

[0074] Rotor magnet 140 is located on the rotor coil assembly 130 and is arranged towards the penetration surface 110b;

[0075] Wherein, the rotor coil assembly 130 rotates to drive the rotor magnet 140 to rotate, and the magnetic field of the rotor magnet 140 penetrates the penetration surface 110b and is coupled with the stirrer in the stirring cup 190 to drive the stirrer to rotate in the stirring cup 190.

[0076] Please refer to Figures 1-10 In the embodiment, the rotor coil assembly 130 generates magnetic force in the state of being electrified, and under the influence of the magnetic field of the stator magnet 120, the rotor coil assembly 130 rotates around its axis. Since the rotor magnet 140 is arranged on the rotor coil assembly 130, the rotor coil assembly 130 drives the rotor magnet 140 to rotate, and the magnetic induction lines of the rotor magnet 140 penetrate the penetration surface 110b and are coupled with the stirrer, so that the rotor magnet 140 is coupled with the stirrer in the stirring cup 190.
