Description

Technical Field

[0001] This utility model relates to the field of food processing tools, and in particular to a magnetic conduction rotation device for a mixer. Background Technology

[0002] A blender is a machine that mechanically extracts juice from fruits or vegetables. Blenders typically consist of a drive mechanism and blades. The drive mechanism rotates the blades at high speed, thus chopping the fruit to produce juice.

[0003] However, traditional blenders use a vertical drive mechanism for their magnetic drives. During this vertical movement, the magnetic field transmission may experience some losses, leading to reduced power transmission efficiency. Furthermore, factors such as the air gap between the magnet and the blades, and the magnetic circuit design, can also affect transmission efficiency. At high speeds, the coupling stability between the magnet and the blades can be affected by external factors, such as magnetic field interference or vibration, causing unstable blade speeds and impacting the juice-making results. For fruits or vegetables with high viscosity, the vertical drive mechanism may not provide sufficient torque, resulting in poor blending performance.

[0004] In summary, the traditional magnetic drive method in mixers has certain shortcomings in terms of transmission efficiency, stability, structural complexity, noise, adaptability, and cost. These shortcomings may affect the performance of the mixer and the user experience. Utility Model Content

Detailed Implementation

[0035] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0036] This utility model provides a magnetic conduction rotation device for a mixer. The mixer 1 includes a mixing container 3 and a base 2. The base 2 is provided with a drive assembly 4, which includes a magnetic drive component 401.

[0037] The mixing container 3 is provided with a driven assembly 5 for mounting the blades, and the driven assembly 5 includes a magnetically attracted driven element 501;

[0038] Both the magnetic drive component 401 and the magnetic follower component 501 are rotatable ring structures forming concentric circles. The magnetic drive component 401 and the magnetic follower component 501 are driven to rotate by magnetic force arranged opposite to each other, and there is no direct contact between the magnetic drive component 401 and the magnetic follower component 501.

[0039] like Figures 1 to 8 As shown in the figure, this is the first embodiment of the present invention. In this case, the magnetic follower 501 is rotatably arranged in an annular shape in the inner ring of the magnetic drive 401.

[0040] Specifically, the stirring container 3 includes a cup body 301 and a detachable cup holder 302 connected to the lower side of the cup body 301, and the driven component 5 is disposed in the cup holder 302;

[0041] The upper side of the base 2 is provided with a recessed groove 201, and a boss 202 is provided around the recessed groove 201. The magnetic drive component 401 is disposed in the cavity of the boss 202.

[0042] The lower end cup holder 302 of the stirring container 3 is placed in the recessed groove 201, and the boss 202 and the magnetic drive 401 are located on the outer ring of the cup holder 302 and the magnetic follower 501.

[0043] Drive assembly 4 includes drive shaft 402 and drive module 403 for controlling the movement of drive shaft 402. Magnetic drive component 401 is fixedly connected to drive shaft 402 and moves synchronously through concave connecting seat 404. The protruding post 405 on the outer ring of concave connecting seat 404 is placed in the cavity of boss 202, and magnetic drive component 401 is embedded in the protruding post 405.

[0044] The driven component 5 includes a cutter 502 and a cutter shaft 503. The magnetically attracted driven member 501 is fixedly installed on the cutter shaft 503 and moves synchronously. The upper end of the cutter shaft 503 passes through the cup holder 302 and is connected to the cutter 502. The cutter 502 is placed inside the cup body 301.

[0045] The drive module 403 drives the drive shaft 402 and the magnetic drive component 401 to rotate, thereby driving the magnetic follower 501 to drive the cutter shaft 503 and the cutter 502 to rotate.

[0046] In this embodiment, when the stirring container 3 is placed on the base 2, the magnetic follower 501 at the bottom of the stirring container 3 is placed in the recessed groove 201 of the base 2, so that the magnetic drive 401 and the magnetic follower 501 at the outer ring boss 202 of the recessed groove 201 are on the same horizontal plane and form concentric circles. Magnetic induction is performed between the magnetic drive 401 and the side of the magnetic follower 501. At this time, there is a magnetic field between the magnetic drive 401 and the magnetic follower 501. When the magnetic drive 401 rotates, the magnetic follower 501 rotates 360 degrees under the action of the magnetic field, thereby driving the blade shaft 503 and the blade 502 to rotate, and thus juicing the fruits and vegetables in the cup 301.

[0047] The side drive has a lever effect, and the farther the force point is from the main shaft, the less force is required at the force point. This makes up for the lack of magnetic force due to the magnet. The magnetic circuit is shorter, the magnetic field is transmitted more directly, energy loss is reduced, and power transmission efficiency is improved. Its structural design is more compact and has more installation space to install more magnets to achieve sufficient torque. In addition, the side magnetic drive reduces vibration, and the noise generated by the mixer during operation is lower, improving the user experience.

[0048] Furthermore, a ring-shaped second mounting seat 504 is fixedly mounted on the cutter shaft 503, and the magnetic follower 501 is embedded in the outer ring of the second mounting seat 504. The protruding post 405 and the second mounting seat 504 are located on the same horizontal plane and form concentric circles.

[0049] When the magnetic follower 501 is installed on the outer edge of the second mounting base 504, the side of the magnetic follower 501 is closer to the magnetic drive 401, its magnetic circuit is shorter, the magnetic field is transmitted more directly, energy loss is reduced, and power transmission efficiency is improved.

[0050] Furthermore, the magnetic drive component 401 is embedded in the protruding post 405, and the protruding post 405 and the concave connecting seat 404 are suspended in the air with a gap between them and the inner wall of the boss 202; the lower side of the second mounting seat 504 is suspended in the air with a gap between it and the bottom wall of the cup seat 302, and the concave connecting seat 404 and the second mounting seat 504 are not in direct contact with the inner wall of the mixer 1, so that the rotation of the magnetic drive component 401 and the magnetic follower 501 is smoother and the resistance is smaller.

[0051] In this embodiment, when the stirring container 3 is placed on the base 2, the magnetic drive 401 senses the magnetic follower 501 and supplies power to the drive module 403 to allow the drive module 403 to start running; when the stirring container 3 is removed from the base 2, the magnetic drive 401 loses the sense of the magnetic follower 501 and cuts off the power to the drive module 403 to prevent the drive module 403 from running, thus ensuring safe use.

[0052] Furthermore, both the magnetic drive component 401 and the magnetic follower component 501 are configured as square magnetic blocks with gaps and arranged in a ring, embedded in the mounting groove 8 on the protruding post 405 and the second mounting base 504. The magnetic surface of the square magnetic blocks is much larger than that of the circular magnets, and the magnetic field transmission is more stable.

[0053] In addition, the magnetic drive 401 and the magnetic follower 501 can also be configured as a single ring structure and embedded in the protruding post 405 and the second mounting base 504 to make the magnetic surface larger.

[0054] Furthermore, a detachment detection component 6 is connected to the lower side of the cup body 301. The detachment detection component 6 includes a connecting seat 601 connected to the lower side of the cup body 301. A detachment detection magnet 602 is embedded in the connecting seat 601. The detachment detection magnet 602 and the magnetic follower 501 simultaneously sense the magnetic drive component 401 to start the drive component 4.

[0055] Specifically, the cup body 301 is connected to the cup holder 302 via the connecting seat 601. The outer ring of the connecting seat 601 is provided with a protrusion 603 for embedding the detachment detection magnet 602, and the recessed groove 201 is provided with a limiting groove 204 corresponding to the protrusion 603.

[0056] In this embodiment, when the cup body 301 is disassembled from the cup holder 302, the cup holder 302 is provided with a magnetic follower 501. If the cup holder 302 is still placed on the base 2, the magnetic follower 501 and the magnetic drive 401 will sense each other and cause the drive assembly 4 to drive the follower assembly 5 to move, while the knife 502 is exposed to the outside and is dangerous.

[0057] Therefore, a detachment detection component 6 is provided on the lower side of the cup body 301. Power can only be supplied to the drive component 4 after the magnetic drive component 401 senses both the detachment detection magnet 602 and the magnetic follower 501 at the same time. When the magnetic drive component 401 senses only either the detachment detection magnet 602 or the magnetic follower 501, the power to the drive component 4 is cut off to prevent the drive component 4 from running, ensuring safe use and ensuring that the machine cannot be started when the blade is placed on the base, thereby improving the safety of the mixer 1.

[0058] Its detachment detection component 6 can also be detachably connected to the cup body 301 via threads. During use, only the cup body 301 and the cup seat 302 are disassembled. The cup body 301 is always connected to the connecting seat 601. The lower side of the connecting seat 601 can be detachably connected to the cup seat 302 via threads. Rubber rings are provided between the cup body 301 and the connecting seat 601, and between the connecting seat 601 and the cup seat 302, to prevent leakage at the connection and strengthen the connection, thereby improving the overall stability.

[0059] Furthermore, the upper end of the drive shaft 402 and the lower end of the cutter shaft 503 are both connected to a rotary bearing 7, and the lower side of the recessed groove 201 is provided with a first fixing groove 203 for limiting the position of the rotary bearing 7.

[0060] The bottom of the cup holder 302 is provided with a second fixing groove 303 for defining the position of the rotating bearing 7. The second fixing groove 303 is arranged along the same longitudinal axis as the first fixing groove 203.

[0061] The upper end of the drive shaft 402 is assisted in rotation by a rotary bearing 7, and the position of the drive shaft 402 and the magnetic drive component 401 is fixed by fixing the rotary bearing 7 in the first fixing groove 203, so that the installation of the drive assembly 4 in the base 2 is more stable.

[0062] The lower end of the cutter shaft 503 is assisted in rotating by a rotary bearing 7, and the position of the cutter shaft 503 and the magnetic follower 501 is fixed by fixing the rotary bearing 7 in the second fixing groove 303, so that the installation of the follower assembly 5 in the cup holder 302 is more stable.

[0063] In addition, the magnetic follower 501 can also be rotatably arranged in a ring on the outer ring of the magnetic drive 401, and its working principle is the same as the above case.

[0064] This invention forms a side magnetic induction transmission by setting the magnetic drive component 401 of the drive assembly 4 and the magnetic follower component 501 of the driven assembly 5 on the same horizontal plane. The magnetic circuit of the side magnetic drive is shorter, the magnetic field transmission is more direct, energy loss is reduced, and power transmission efficiency is improved. Its structural design is more compact, with more installation space to accommodate more magnets to achieve sufficient torque. In addition, the side magnetic drive reduces vibration, and the noise generated by the mixer during operation is lower, improving the user experience.

[0065] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
