Fig. 4 is a structural diagram of the magnetic driving element with a third magnetic element installed thereon according to a preferred embodiment of the present invention. As shown in fig. 3 and 4, the driving shaft of the driving motor 211 is a hollow shaft, at this time, the center of the cross bar is provided with a through hole 2121 corresponding to the hollow shaft of the driving shaft, that is, the hollow shaft penetrates through the cross bar through the through hole 2121, meanwhile, a coaxially arranged ejector rod 2122 is penetrated in the hollow shaft of the driving shaft, the upper end of the ejector rod 2122 extends into the through hole 2121 on the cross bar, that is, an installation space is provided for the ejector rod 2122 through the hollow shaft of the driving shaft and the through hole 2121 of the cross bar, and meanwhile, the rotation of the driving shaft is not influenced, so that mutual independence of the structures is realized. And, the top of the ejector 2122 is provided with a third magnetic member 2123, and meanwhile, two magnetic poles of the third magnetic member 2123 are respectively opposite to two magnetic poles of the two first magnetic members 22 that are close to each other, so that when two ends of the second magnetic member 32 are respectively attracted by the two first magnetic members 22, the magnetic poles at two ends of the third magnetic member 2123 are just opposite to the magnetic poles at two ends of the second magnetic member 32, so that the second magnetic member 32 is subjected to the repulsive force of the third magnetic member 2123, and the magnetic force of the third magnetic member 2123 is greater than that of any one first magnetic member 22, so that when the second magnetic member 32 is subjected to the repulsive force of the third magnetic member 2123, the second magnetic member 32 will be far away from the first magnetic member 22, thereby moving a distance toward the surface of the red wine, that the mating member 3 will move from the bottom of the red wine to the middle of the red wine, and at the same time, the repulsive force 3 will continue to stir the red wine under the action of the mating member under the action of the inertia mating member, so as to achieve more sufficient mixing of the red wine, so as to achieve sufficient mixing, and the magnetic force that the magnetic force of the third magnetic member 3 will continue to be retracted from the bottom of the red wine, and the magnetic member 22, and the magnetic force of the magnetic member 3 will continue to be retracted, and the magnetic member 22, and the magnetic force of the magnetic member will continue to be retracted, and the magnetic member 22, so as to be retracted, and the magnetic member, so as to be driven by the magnetic force of the magnetic member, and the magnetic member 22, and the magnetic force of the magnetic member, and the magnetic member 3, and the magnetic member 22, so as to be retracted.

More specifically, the third magnetic element 2123 is a permanent magnet, so that the use is convenient, and the manufacturing and using costs are low. And, the ejector rod 2122 is provided with a lifting structure 5, at this time, the lifting structure 5 is arranged at the bottom of the ejector rod 2122, the lifting structure 5 is a telescopic driver, and the telescopic driver is a linear motor, that is, the height of the ejector rod 2122 is adjusted by the lifting structure 5, that is, when the lifting structure 5 controls the ejector rod 2122 to extend out, the third magnetic member 2123 protrudes from the first magnetic member 22, so that the magnetic force applied to the second magnetic member 32 by the third magnetic member 2123 is greater than the magnetic force applied to the second magnetic member 32 by the first magnetic member 22, so that the second magnetic member 32 is repelled, thereby the mating member 3 moves from the bottom of the red wine to the middle of the red wine, and continues to rotate under the inertia effect, and thus the red wine is more sufficiently stirred. When the lifting structure 5 controls the ejector rod 2122 to retract, the third magnetic member 2123 can retract below the first magnetic member 22, so that the magnetic force applied to the second magnetic member 32 by the third magnetic member 2123 is significantly smaller than the magnetic force applied to the second magnetic member 32 by the first magnetic member 22 or the third magnetic member 2123 does not act on the second magnetic member 32, and the second magnetic member 32 can automatically return under the action of its own gravity or the attractive force of the first magnetic member 22, so that the fitting member 3 can rotate continuously along with the magnetic driving member 2, thereby stirring red wine and satisfying the sobering requirement. It should be noted that the lifting structure 5 works intermittently, i.e. after moving once and returning for a while, it will move again after waiting for a while, so that the movement of the fitting member 3 moving from the bottom of the red wine to the middle of the red wine is also intermittent, thereby ensuring that the fitting member 3 can have enough time to follow the rotation by the action force of the first magnetic member 22, and ensuring the sobering effect. In addition, when the engaging member 3 is repelled by the third magnetic member 2123, the effect can be achieved by moving only a small distance, so that the magnetic force of the third magnetic member 2123 and the stroke of the lifting structure 5 do not need to be too large, and the engaging member 3 can be separated from the bottom of the decanter 1.

In addition, in this embodiment, except for the case that the third magnetic member 2123 is a permanent magnet, the third magnetic member 2123 may also be an electromagnet, and at this time, the ejector rod 2122 is also provided with a hollow structure, and a conductive wire of the electromagnet passes through the hollow of the ejector rod 2122, so that the wiring is convenient, and a condition is provided for the circuit conduction of the electromagnet. That is, after the electromagnet was switched on, the fitting member 3 was repelled, so that the fitting member 3 moved from the bottom of the red wine to the middle of the red wine and continued to rotate under the inertia, and after the electromagnet was switched off, the fitting member 3 would move toward the bottom of the red wine under the action of the deadweight and the first magnetic member 22, and the sobering effect could be improved as well. It is worth pointing out that the magnetic force of the third magnetic member 2123 can be adjusted by the magnitude of the energizing current, so that the adjustment is more convenient, and meanwhile, the third magnetic member 2123 has no magnetic force after being powered off, so that the effect is better.

The electronic decanter provided by the embodiment comprises a decanting container 1, a magnetic driving piece 2 and a matching piece 3; through installing first magnetic part 22 on magnetic drive piece 2's driving head 21, fitting member 3 is placed in sobering up container 1 hold the chamber 11 and be provided with the second magnetic part 32 with first magnetic part 22 inter attraction, make driving head 21 when rotating, can drive fitting member 3 to rotate at an interval, thereby make fitting member 3 stir the red wine of splendid attire in the chamber 11 that holds of sobering up container 1, make red wine fully contact with air and oxidation, reach the purpose of fully sobering up, the taste of red wine has been promoted, and simultaneously, need not manual stirring, whole journey autogiration, sobering up efficiency is higher, the effect is better, better high-quality when having satisfied people and drinking is pursued to red wine, do benefit to the expansion of red wine market.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
