DETAILED DESCRIPTION

[0021] Specific embodiments of the present application are described in conjunction with the accompanying drawings and the following description to teach those skilled in the art how to make and use the best mode of the present application. In order to teach the principles of the application, some conventional aspects have been simplified or omitted. Those skilled in the art should understand that variations from these embodiments fall within the scope of the present application. Those skilled in the art should understand that the following features can be combined in various ways to form multiple variations of the present application. Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this application are only for the convenience of description and are not intended to limit the scope of the implementation of the present invention. Changes or adjustments to their relative relationships should also be regarded as the scope of the implementation of the present invention without substantial changes in the technical content. Therefore, the present application is not limited to the specific embodiments described below, but is only limited by the claims and their equivalents.

[0022] like Figures 1 to 3 As shown, this embodiment relates to a magnetic stirring coffee cup, which includes a cup body 1, a cup cover 2, a filter 3, a stirring device 4 and a magnetic attraction device 5. The cup body 1 is threadedly connected to the cup cover 2, the filter 3 is clamped in the cup body 1, and the stirring device 4 is connected to the center of the filter 3. The magnetic attraction device 5 includes an annular magnet 51 and a fan blade magnet 52. The annular magnet 51 is arranged at intervals along the inner wall of the cup body 1, and the fan blade magnet 52 is installed on the stirring device 4. When the fan blade magnet 52 on the stirring device 4 moves down to the same height as the annular magnet 51, the stirring device 4 rotates under the action of the magnetic force.

[0023] In an embodiment of the present application, the stirring device 4 includes a through rod 41 and a rotating blade 42. The lower end of the through rod 41 is inserted into the bottom center of the filter 3, and the rotating blade 42 is rotatably connected to the through rod 41. Specifically, the rotating blade 42 includes a rotating sleeve 421 and blades 422. The blades 422 are provided with 8 pieces. The blades 422 are evenly spaced along the outer circumference of the rotating sleeve 421. The blades 422 are arranged in an inclined manner. The angle between the blades 422 and the vertical direction is 25°. Each blade 422 is installed with a blade magnet 52. The through rod 41 is provided with a step 411. The rotating sleeve 421 is sleeved on the through rod 41 and its lower end is supported by the step 411. The upper end is limited by an O-ring 44 sleeved on the through rod 41.

[0024] In addition, the center of the drain screen 3 is provided with a positioning through-hole 31, the lower end of a through rod 41 passes through the positioning through-hole 31, and a return spring 43 is sleeved on the lower part of the through rod 41. The upper end of the return spring 43 abuts against the bottom surface of the step 411, and the lower end of the return spring 43 abuts against the drain screen 3. The upper end of the through rod 41 abuts against the cup cover 2. Specifically, the lower end of the through rod 41 is provided with two elastic semi-cones 412, and the through rod 41 is clamped under the drain screen 3 by the elastic semi-cones 412.

[0025] In an embodiment of the present application, the cup body 1 includes an inner liner 11 and an outer shell 12, and a vacuum layer 13 is provided between the inner liner 11 and the outer shell 12. The annular magnet 51 is fixed to the outer wall of the inner liner 11 through a welding sheet 53. The annular magnet 51 is tightly attached to the inner liner 11, reducing the distance between the annular magnet 51 and the fan blade magnet 52, which can strengthen the repulsive force between the two and improve the rotation effect of the rotating fan blade 42.

[0026] The working principle of this utility model is

[0027] Add coffee to the colander 3, close the cup cover 2, and rotate the cup cover 2 downward. Since the top of the through rod 41 is in contact with the cup cover 2, the stirring device 4 is driven downward when the cup cover 2 moves downward. When the fan magnet 52 on the rotating fan blade 42 is at the same height as the annular magnet 51 on the cup body 1, the mutual repulsive force between the fan magnet 52 and the annular magnet 51 causes the rotating fan blade 42 to rotate, thereby stirring the coffee in the colander 3 and dissolving the coffee in the water.

[0028] Based on the same principle, this application can be used for stirring and dissolving other solid powders.

[0029] Since those skilled in the art can easily think of it, any modifications, equivalent substitutions, improvements, etc. made within the concept and principle of the application should be included in the scope of the claims of this application.
