Description

Technical Field

[0001] The invention relates to the technical field of stirring cups, and in particular to a magnetic stirring structure and a magnetic stirring cup. Background Art

[0002] The magnetic stirring structure is a cup that uses the magnetic stirring principle to mix liquids. The magnetic stirring structure has a built-in magnetic stirring bar (a small magnetic bar) and a motor at the bottom to drive the magnetic field to rotate, causing the stirring bar to rotate rapidly in the cup, thereby evenly stirring the liquid.

[0003] The traditional magnetic stirring structure is driven by a motor. A magnetic sheet is arranged on the output shaft of the motor. The rotation of the motor drives the magnetic sheet to rotate, and then the magnetic sheet drives the magnetic stirring bar in the stirring cup to rotate to complete the stirring.

[0004] However, the motor of a conventional magnetic stirring structure is generally large, which makes the bottom of the magnetic stirring structure very thick, and produces very loud noise during operation, making it very inconvenient to use.

[0005] With the advancement of technology, the magnetic stirring structure uses a magnetic induction coil to drive the magnetic sheet to rotate, so that the magnetic sheet drives the magnetic stirring bar in the stirring cup to rotate to complete the stirring.

[0006] Although the use of a magnetic induction coil to drive can reduce the bottom thickness of the magnetic stirring structure, since a large number of magnetic induction coils are required, the bottom thickness of the magnetic stirring structure will still be relatively thick, which is inconvenient to use.

[0051] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

In addition, the terms "first", "second" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0053] The present invention provides a magnetic stirring structure 100, comprising:

[0054] A magnetic driving plate 110 , on which a magnetic induction circuit 111 is etched;

[0055] A rotating assembly 120, one end of which is rotatably connected to the magnetic driving plate 110, and the rotating assembly 120 is coupled to the magnetic induction circuit 111;

[0056] A driving magnet 130 is mounted on one end of the rotating assembly 120 away from the magnetic driving plate 110;

[0057] A stirring bar 140 coupled to the driving magnet 130;

[0058] The magnetic induction circuit 111 generates a magnetic field to drive the rotating assembly 120 to rotate, thereby driving the driving magnet 130 to rotate, so that the driving magnet 130 drives the stirring element 140 to stir.

[0059] Please refer to Figure 1-Figure 7 In this embodiment, when in use, the magnetic driving plate 110 controls the magnetic induction circuit 111 to be energized, and the magnetic induction circuit 111 is energized to generate a magnetic field. Since the rotating component 120 is coupled with the magnetic induction circuit 111, the changing magnetic field generated by the magnetic induction circuit 111 acts on the rotating component 120, controlling the rotating component 120 to rotate, thereby rotating the driving magnet 130, and then driving the stirring bar 140 to rotate through the driving magnet 130, so that the stirring bar 140 stirs the liquid to achieve a stirring effect.

[0060] Since a magnetic induction circuit 111 is etched on the magnetic driving plate 110 to generate a magnetic field, no external magnetic induction coil is required, thereby reducing the thickness of the driving structure, thereby reducing the volume and thickness of the entire stirring structure, and making it more convenient for users to use.

[0061] It should be noted that, since the magnetic induction circuit 111 is etched on the magnetic driving plate 110 , the magnetic induction circuit 111 is directly located on the magnetic driving plate 110 , thereby reducing the overall thickness.

[0062] It should be noted that the magnetic drive plate 110 is a circuit board, which is electrically connected to the magnetic induction circuit 111. By changing the direction and magnitude of the current, the direction and strength of the magnetic field of the magnetic induction circuit 111 are adjusted to drive the rotating component 120 to rotate.

[0063] The stirring bar 140 is a magnetic block, and the driving magnet 130 is a magnetic block.

[0064] Preferably, the magnetic induction circuit 111 is multi-layered, and the multi-layered magnetic induction circuit 111 is stacked on the magnetic driving plate 110, and the magnetic induction circuits 111 of two adjacent layers are connected end to end.

[0065] Please refer to Figure 1-Figure 7 In this embodiment, since a multi-layer magnetic induction circuit 111 is etched on the magnetic driving plate 110, the magnetic force of the magnetic field generated by the multi-layer magnetic induction circuit 111 can better act on the rotating component 120, thereby driving the rotating component 120 to rotate to meet the rotation speed requirement of the stirrer 140.

[0066] In this embodiment, two adjacent layers of magnetic induction circuits 111 are connected end to end to achieve electrical connection, that is, the tail end of the upper layer of magnetic induction circuits 111 is electrically connected to the head end of the lower layer of magnetic induction circuits 111 to achieve synchronous generation of a magnetic field to form a magnetic field with stronger magnetic force. It should be noted that the number of layers of the magnetic induction circuits 111 is not less than 10 layers. If it is less than 10 layers, the number of layers of the magnetic induction circuits 111 cannot be reached, and the strength of the magnetic field will be reduced, and the stirring speed of the stirrer 140 cannot be driven to the stirring speed, thereby making the stirring effect of the stirrer 140 poor.

[0067] It should be further explained that, when a plurality of circuit boards are stacked to generate a magnetic field to drive the stirrer 140 to rotate, the thickness of the circuit boards will still further affect the overall thickness to a certain extent, thus affecting the use.

[0068] In the present technical solution, a multi-layer magnetic induction circuit 111 is etched on the magnetic driving plate 110. During the stacking process, only the magnetic induction circuit 111 is stacked instead of stacking a plurality of magnetic driving plates 110. Therefore, the thickness of the magnetic driving plate 110 after etching does not increase much, so as to further reduce the overall thickness and volume of the driving structure.

[0069] Preferably, the magnetic induction circuit 111 includes a plurality of magnetic induction areas 111 a , and the plurality of magnetic induction areas 111 a are arranged at equal angles with the center of the magnetic driving plate 110 as the center.

[0070] Please refer to Figure 1-Figure 7 In this embodiment, a single magnetic induction circuit 111 includes multiple magnetic induction areas 111a, and the multiple magnetic induction areas 111a jointly generate a magnetic field to form a magnetic field with a stronger magnetic force, so that the speed of driving the stirrer 140 to rotate is higher to meet the stirring requirements of the stirrer 140.

[0071] The plurality of magnetic induction areas 111a are arranged at equal angles with the center of the magnetic driving plate 110 as the center, so that one side of the entire magnetic driving plate 110 is covered with the magnetic induction area 111a to avoid the uneven magnetic force of the magnetic field affecting the stirring effect of the stirrer 140.

[0072] It should be noted that, in the present embodiment, the magnetic induction area 111a is arranged in a fan-shaped surrounding manner to form a plurality of magnetic fields on the magnetic driving plate 110, and the plurality of magnetic fields work together to enhance the magnetic force, so that the rotating assembly 120 rotates at a faster speed, so that the rotating assembly 120 drives the driving magnet 130 to rotate at a faster speed, and then drives the stirring bar 140 to rotate, so that the stirring bar 140 rotates at a faster speed and the stirring effect is better. In other embodiments, the magnetic induction area 111a can be surrounded in a triangular, annular, rectangular, etc. manner, including but not limited to the above-mentioned surrounding manners.

[0073] Preferably, the magnetic induction circuit 111 is disposed on a side close to the driving magnet 130 .

[0074] Please refer to Figure 1-Figure 7 In this embodiment, since the magnetic induction circuit 111 is arranged on the side of the magnetic driving plate 110 close to the driving magnet 130, the magnetic force of the magnetic induction circuit 111 can directly act on the rotating component 120, thereby driving the driving magnet 130 to rotate better, making the rotation speed of the driving magnet 130 faster.

[0075] Preferably, the magnetic driving plate 110 is provided with a mounting hole 110a, and the rotating assembly 120 includes:

[0076] A connecting shaft 121, one end of which passes through the mounting hole 110a to the other side of the magnetic driving plate 110 and is fixedly connected to the driving magnet 130;

[0077] A transmission magnet 122 is mounted on the connecting shaft 121 and coupled with the magnetic induction circuit 111;

[0078] The shielding member 123 is mounted on the connecting shaft 121 , and the transmission magnet 122 and the driving magnet 130 are respectively located on two sides of the shielding member 123 .

[0079] Please refer to Figure 1-Figure 7 In this embodiment, the magnetic induction circuit 111 generates a magnetic field acting on the transmission magnet 122. Under the action of the magnetic field of the magnetic induction circuit 111, the transmission magnet 122 is driven to rotate around the central axis of the connecting shaft 121. Since the transmission magnet 122 is installed on the connecting shaft 121, the rotation of the transmission magnet 122 drives the connecting shaft 121 to rotate, and the connecting shaft 121 rotates in the mounting hole 110a, so that the connecting shaft 121 drives the driving magnet 130 to rotate, and the rotation of the driving magnet 130 further drives the stirring rod 140 to rotate, thereby achieving stirring.

[0080] It should be noted that the transmission magnet 122 is a circular ring magnet, and in other embodiments it may be a circular ring structure composed of multiple bar magnets. When the magnetic induction circuit 111 generates a changing magnetic field, the transmission magnet 122 will be driven to move under the action of magnetic force, so that the transmission magnet 122 rotates around the connecting shaft 121, and further drives the connecting shaft 121 to rotate around its axis.

[0081] The mounting hole 110a is a circular through hole.

[0082] The connecting shaft 121 is generally a column with a boss at one end and a round rod-shaped column at the other end.

[0083] In this embodiment, since the transmission magnet 122 and the driving magnet 130 are respectively located on both sides of the shielding member 123, during use, the magnetic field of the transmission magnet 122 will not affect the magnetic field of the driving magnet 130, thereby making the driving magnet 130 have a better magnetic force on the stirring bar 140, avoiding the transmission magnet 122 from causing magnetic interference to the stirring bar 140, and further making the driving magnet 130 have a better magnetic force effect on the stirring bar 140, thereby improving the stirring effect of the stirring bar 140.

[0084] It should be noted that the shielding member 123 is in the shape of a circular cover with one side concave inwards, and is a magnetic yoke, so as to shield the magnetic force generated by the transmission magnet 122 and the magnetic driving plate 110 from interfering with the stirrer 140 .

[0085] It should be further explained that in the existing magnetic induction coil, there is no shielding member 123, so that the magnetic field generated by the magnetic induction coil will offset and intersect with the magnetic field generated by the driving magnet 130, thereby affecting the rotation of the stirrer 140, and the stirrer 140 cannot achieve the best stirring effect.

[0086] In the present solution, a shielding member 123 is used to shield the magnetic field except for the driving magnet 130 and the stirring rod 140, so as to separate the magnetic field between the driving magnet 130 and the stirring rod 140, avoid interference of multiple magnetic fields on the magnetic field between the driving magnet 130 and the stirring rod 140, and improve the smoothness and efficiency of the movement of the stirring rod 140.

[0087] Preferably, in the axial direction of the connecting shaft 121 , the projection area of ​​the shielding member 123 partially blocks the projection area of ​​the magnetic induction line 111 .

[0088] Please refer to Figure 1-Figure 7 In this embodiment, since the projection area of ​​the shielding member 123 partially blocks the projection area of ​​the magnetic driving plate 110 in the axial direction of the connecting shaft 121, and the shielding member 123 shields the area where the magnetic driving plate 110 generates magnetic force, the magnetic influence of the magnetic induction circuit 111 on the stirring bar 140 is reduced, making the stirring of the stirring bar 140 smoother.

[0089] It should be noted that, along the direction from the stirrer 140 to the magnetic driving plate 110 , in the axial direction of the connecting shaft 121 , the projection area of ​​the shielding member 123 blocks the projection area of ​​the magnetic induction line 111 .

[0090] Preferably, a side of the shielding member 123 close to the magnetic driving plate 110 is inwardly recessed to form a receiving groove 123 a , and the transmission magnet 122 is received in the receiving groove 123 a .

[0091] Please refer to Figure 1-Figure 7 In this embodiment, since a accommodating groove 123a is recessed on the side of the shielding member 123 close to the magnetic driving plate 110, the accommodating groove 123a is used to install the transmission magnet 122, so that a shielding space is formed between the shielding member 123, the connecting shaft 121 and the magnetic driving plate 110 to ensure that the magnetic field of the transmission magnet 122 will not affect the magnetic fields of the driving magnet 130 and the stirring rod 140.

[0092] Preferably, the shielding member 123 is located on a side of the magnetic driving plate 110 close to the stirring bar 140 , and the connecting shaft 121 passes through the shielding member 123 .

[0093] Please refer to Figure 1-Figure 7 In this embodiment, since the shielding member 123 is located on the side of the magnetic driving plate 110 close to the stirring rod 140, during use, the magnetic field generated by the magnetic induction circuit 111 will fill the receiving groove 123a and will not interfere with the driving magnet 130 and the stirring rod 140, so as to improve the stirring effect of the stirring rod 140.

[0094] The connecting shaft 121 passes through the geometric center of the shielding member 123 to ensure that the connecting shaft 121 can rotate around its axis driven by the transmission magnet 122 .

[0095] Preferably, the rotating assembly 120 further includes:

[0096] A first mounting member 124, one end of which abuts against a side of the magnetic driving plate 110 away from the stirring element 140, and the other end of which passes through the mounting hole 110a and extends to the other side of the magnetic driving plate 110;

[0097] The second mounting member 125 is disposed on a side of the magnetic driving plate 110 close to the stirring bar 140, one end of the connecting shaft 121 abuts against an end of the first mounting member 124 away from the stirring bar 140, and the other end penetrates the first mounting member 124 and the second mounting member 125 and is fixedly connected to the driving magnet 130;

[0098] The connecting member 126 has one end fixedly connected to one end of the connecting shaft 121 away from the magnetic driving plate 110, and the other end passes through the shielding member 123 and is fixedly connected to the driving magnet 130. The connecting member 126 abuts against the shielding member 123, and the shielding member 123 is located between the connecting member 126 and the driving magnet 130.

[0099] Please refer to Figure 1-Figure 7 In this embodiment, the end of the connecting shaft 121 away from the stirring bar 140 is mounted on the magnetic driving plate 110 through the first mounting member 124 and the second mounting member 125. The first mounting member 124 and the second mounting member 125 are clamped on both sides of the magnetic driving plate 110, thereby realizing the installation of the connecting shaft 121. At the same time, the connecting shaft 121 passes through the first mounting member 124 and the second mounting member 125 in sequence, thereby ensuring the rotation of the connecting shaft 121, and the first mounting member 124 and the second mounting member 125 ensure the stability of the connecting shaft 121 during the rotation process.

[0100] The first mounting member 124 and the second mounting member 125 are substantially cylindrical with a “T”-shaped cross section and are used to mount the connecting shaft 121 .

[0101] Please refer to Figure 1-Figure 7 In this embodiment, the other end of the connecting shaft 121 is fixed together with the shielding member 123 by the connecting member 126 to form a whole, so that the transmission magnet 122 can drive the connecting shaft 121 to rotate during the movement, thereby driving the driving magnet 130 to rotate, so as to drive the stirring rod 140 to rotate.

[0102] The connecting member 126 is a stepped circular boss, and the shielding member 123 is fixed to the end of the connecting shaft 121 away from the magnetic driving plate 110 by abutting and penetrating, so as to achieve installation, thereby ensuring the shielding effect of the shielding member 123 .

[0103] A stirring cup (not shown in the figure), comprising the magnetic stirring structure 100 as described above;

[0104] The mixing cup also includes:

[0105] The cup body (not marked in the figure) has a stirring chamber (not marked in the figure) formed inside and an installation chamber (not marked in the figure) formed at the bottom. The stirrer 140 is placed in the stirring chamber, and the magnetic drive plate 110, the rotating assembly 120 and the driving magnet 130 are installed in the installation chamber.

[0106] Please refer to Figure 1-Figure 7 In this embodiment, the magnetic driving plate 110 is energized to enable the magnetic induction circuit 111 to generate a magnetic field. Under the influence of the magnetic field of the magnetic induction circuit 111, the rotating component 120 is driven to rotate, thereby driving the driving magnet 130 to rotate, and finally driving the stirring rod 140 to stir in the stirring chamber to achieve stirring.

[0107] Since a single-layer magnetic driving plate 110 is used and an induction circuit is etched on the magnetic driving plate 110 , there is no need to use a multi-layer magnetic induction coil, thereby reducing the thickness of the driving structure, making the magnetic stirring structure 100 thinner and having a better use effect.

[0108] It should be noted that the cup body is substantially cylindrical, the stirring cavity is substantially an open cavity, and the installation cavity is substantially the installation space at the bottom of the cup body.
