Description

Technical Field

[0001] The utility model relates to a magnetic stirring device. Background Art

[0002] In recent years, a number of cooking robots have been introduced on the market, bringing great convenience to restaurants. When a cooking robot is working, sometimes it is necessary to provide a thickening liquid for a wok, and it is necessary to stir the starch and water evenly.

[0003] Chinese Patent with the publication number CN 219463212 U discloses a thickening material stirring device. A support frame is placed in a cup body, and the support frame is arranged at the bottom of the cup body; a stirring component is also provided. The stirring component includes a connecting shaft, a stirring blade and a magnet. The connecting shaft is vertically arranged on the support frame. The magnet is arranged at one end of the connecting shaft close to the bottom of the cup body. A stirring blade is arranged at the other end of the connecting shaft. There is a gap between the magnet and the bottom of the cup body; a control coil is arranged outside the cup body and is located below the magnet. This solution requires a bracket to be arranged in the cup body, and the structure is relatively complex. Moreover, the structure is complex and not easy to clean, and it is easy to generate harmful substances such as mildew, which is harmful to health.

[0004] Therefore, it is necessary to design a new magnetic stirring device. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a magnetic stirring device, which has a simple and ingenious structure and is convenient and practical.

[0006] The technical solution of the utility model is as follows:

[0007] A magnetic stirring device includes a cup body, a magnetic rotor and a rotor driving unit;

[0008] The magnetic rotor is placed in the cup body in a free state; at least one N magnetic pole and at least one S magnetic pole are provided in the magnetic rotor; protrusions are provided on the periphery of the magnetic rotor; or there may be no protrusions, such as a rotor in the shape of a capsule (or an olive ball).

[0009] The rotor driving unit is arranged outside the cup body and is located at the bottom of the cup body; the rotor driving unit is used to generate a rotating magnetic field to drive the magnetic rotor to rotate.

[0010] The rotor driving unit is a flat motor. A pair or more pairs of magnetic poles are provided on the flat motor. The multiple pairs of magnetic poles are evenly arranged along the circumference of the flat motor, and the polarities of adjacent magnetic poles are opposite.

[0011] There are 3 pairs of magnetic poles on the flat motor, including 3 N magnetic poles and 3 S magnetic poles.

[0012] The rotor driving unit is a motor stator including multiple pairs of magnetic poles.

[0013] The magnetic rotor is provided with one N magnetic pole and one S magnetic pole.

[0014] The protrusion is a blade.

[0015] There are 3 - 6 protrusions evenly arranged around the magnetic rotor.

[0016] Beneficial effects:

[0017] For the magnetic stirring device of the present utility model, a magnetic rotor is used as the stirrer. Since the magnetic rotor is not fixedly connected to the cup body but is arranged in a free state, it is easy to clean and there is no installation problem. It is flexible and convenient to use, and is particularly suitable for application on a cooking robot. Description of the drawings

[0022] The following will further describe the present utility model in detail with reference to the drawings and specific embodiments:

[0023] Embodiment 1: As Figures 1-3 shown, a magnetic stirring device includes a cup body 301, a magnetic rotor 302, and a rotor drive unit 303;

[0024] The magnetic rotor is placed in the cup body in a free state, that is, the magnetic rotor is not connected to the cup body; the magnetic rotor is provided with one N magnetic pole and one S magnetic pole; one end is the N pole and the other end is the S pole, and there are 5 protrusions 304 around the magnetic rotor;

[0025] The rotor drive unit is arranged outside the cup body and at the bottom of the cup body; the rotor drive unit is used to generate a rotating magnetic field to drive the magnetic rotor to rotate.

[0026] The rotor drive unit is a flat motor, and there are 3 pairs of magnetic poles (including 3 N magnetic poles and 3 S magnetic poles) on the flat motor. The 3 pairs of magnetic poles are evenly arranged along the circumference of the flat motor, and the polarities of adjacent magnetic poles are opposite.

[0027] The rotor drive unit can also be a motor stator including multiple pairs of magnetic poles.

[0028] The raised portion is a blade, so the magnetic rotor is an impeller with magnetic poles. The entire component rotating in the liquid can be collectively referred to as the rotor, regardless of whether it has blades (or other raised portions).

[0029] The cup body is a round-bottomed container. The working principle of the present invention is that six magnets are installed on the flat motor as shown in Figure 2 the figure. When the motor rotates, the driving magnetic field rotates continuously, and the magnetic rotor inside the container is driven to rotate through magnetic induction, thereby stirring the liquid and completing the preparation of the thickening agent.

[0030] Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
