Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of stirring cups, specifically to a driving disc and stirring structure. Background Technology
[0002] Stirring cups are frequently used to mix various powders or liquids to ensure they are homogeneous and meet the required specifications.
[0003] There are two types of existing stirring cups. One type uses a motor to drive a magnet to rotate, which in turn drives a stir bar to stir the powder or liquid in the cavity to achieve a uniform mixing state. However, this magnetic drive structure uses a motor to drive it, which generates a lot of noise during the driving process, thus affecting its use.
[0004] Another method involves using a magnetic induction coil to generate a changing magnetic field. This changing magnetic field drives a magnet to rotate, which in turn moves a stir bar, thus mixing the powder or liquid within the cavity to achieve a uniform mixture. While using a magnetic induction coil to drive the stir bar can reduce noise, the magnetic transmission process, from the magnetic induction coil to the magnet, results in magnetic loss. Furthermore, the distance between the magnetic induction coil and the magnet further weakens the magnetic force exerted by the coil on the magnet, consequently affecting the stir bar's rotational speed and leading to less effective mixing.

[0036] This utility model proposes a drive disk 100, comprising:
[0037] The disk body 110 is rotatably connected to an external magnetic drive structure;
[0038] A driving magnet 120 is disposed on the disk body 110 and coupled to an external magnetic drive structure and a stirrer;
[0039] A magnetic force conduction element 130 is located between the driving magnet 120 and the external magnetic force driving structure. The magnetic force conduction element 130 is used to guide the external magnetic force driving structure to the magnetic force direction between the driving magnet 120 and the external magnetic force driving structure.
[0040] Please refer to Figures 1-4 In this embodiment, during use, the external magnetic drive structure generates magnetic force. Since the magnetic conductor 130 is located between the drive magnet 120 and the external magnetic drive structure, the magnetic force generated by the external magnetic drive structure is guided by the magnetic conductor 130 to act on the drive magnet 120, increasing the magnetic force of the magnetic drive structure on the drive magnet 120, avoiding magnetic force loss of the magnetic drive structure, thereby increasing the magnetic force effect of the drive magnet 120 on the stir bar, thereby increasing the stirring speed of the stir bar, and thus making the stirring effect better.
[0041] It should be noted that the disc body 110 is disc-shaped, and the disc body 110 is used to provide a mounting base platform for the drive magnet 120 and the magnetic force transmission component 130.
[0042] The driving magnet 120 is a magnet, such as a bar magnet or a ring magnet. In this embodiment, it is a bar magnet, including but not limited to the above-mentioned magnets.
[0043] The magnetic conductor 130 is a magnetic yoke, which has the same shape as the driving magnet 120 in this embodiment.
[0044] Preferably, the magnetic conductor 130 is disposed on the disk body 110 and located between the disk body 110 and the driving magnet 120.
[0045] Please refer to Figures 1-4 In this embodiment, since the magnetic force conduction element 130 is installed on the disk body 110, the magnetic force conduction element 130 will not detach as the drive magnet 120 rotates, thus being firmly installed between the disk body 110 and the drive magnet 120.
[0046] It should be noted that the magnetic force transmission component 130 is fixed by means of adhesive, snap-fit, etc. The magnetic force transmission component 130 is one of soft magnet, pure iron or low carbon steel, and in this embodiment it is pure iron.
[0047] Preferably, the magnetic force conduction element 130 is located between the stir bar and the driving magnet 120, and the magnetic force conduction element 130 is used to guide the magnetic force direction between the stir bar and the driving magnet 120.
[0048] In another embodiment, a magnetic force conduction element 130 is disposed between the stir bar and the drive magnet 120 to guide the magnetic force direction between the stir bar and the drive magnet 120, thereby enhancing the magnetic force between the drive magnet 120 and the stir bar, so as to better enhance the magnetic force effect and thus enhance the stirring effect of the stir bar.
[0049] It should be further noted that in other embodiments, magnetic conductors 130 can be provided on both sides of the driving magnet 120 to further enhance the magnetic guiding effect and further increase the stirring speed.
[0050] Preferably, a receiving groove 110a is provided on one side of the disc body 110, and the driving magnet 120 and the magnetic force conduction member 130 are received in the receiving groove 110a.
[0051] Please refer to Figures 1-4 In this embodiment, the drive magnet 120 and the magnetic force transmission component 130 are both installed in the receiving groove 110a, so that the disk body 110, the drive magnet 120 and the magnetic force transmission component 130 form an integral connection, so as to avoid the magnetic force transmission component 130 or the disk body 110 being displaced during the rotation of the drive magnet 120, thereby affecting the stability of the movement of the drive magnet 120.
[0052] It should be noted that the shape of the receiving groove 110a is the same as the shape of the driving magnet 120.
[0053] Preferably, a positioning post 111 is provided protruding on the disk body 110, and the positioning post 111 passes through the magnetic force conduction member 130 and the driving magnet 120.
[0054] Preferably, the magnetic conductor 130 has a first mounting hole 130a, the driving magnet 120 has a second mounting hole 120a, and the positioning post 111 passes through the first mounting hole 130a and the second mounting hole 120a in sequence.
[0055] Please refer to Figures 1-4 In this embodiment, the magnetic force conduction component 130 and the driving magnet 120 are installed in the receiving groove 110a by the positioning column 111, so that the driving magnet 120 and the magnetic force conduction component 130 can be firmly fixed in the receiving groove 110a, avoiding displacement of the driving magnet 120 or the magnetic force conduction component 130, thereby affecting the rotation effect of the disk 110.
[0056] During the process of the drive magnet 120 driving the disk 110 to rotate, since the drive magnet 120 is installed in the receiving groove 110a through the positioning post 111, the drive magnet 120 can drive the disk 110 and the magnetic force transmission component 130 to rotate together.
[0057] It should be noted that by having the positioning pin 111 pass through the first mounting hole 130a and the second mounting hole 120a in sequence, it is easier to install the drive magnet 120 and the magnetic force transmission component 130 onto the disk body 110, so as to achieve faster assembly.
[0058] The first mounting hole 130a and the second mounting hole 120a are both circular through holes, and the positioning post 111 is a cylindrical rod.
[0059] The driving magnet 120 is attached to the peripheral wall of the receiving groove 110a, and the magnetic force conduction element 130 is attached to the peripheral wall and bottom wall of the receiving groove 110a.
[0060] Preferably, the driving magnet 120 blocks the magnetic force conduction element 130.
[0061] Please refer to Figures 1-4 In this embodiment, since the driving magnet 120 blocks the magnetic force conduction member 130, the magnetic force conducted by the magnetic force conduction member 130 can be fully applied to the driving magnet 120 to increase the magnetic force, thereby making the magnetic force of the driving magnet 120 on the stir bar stronger.
[0062] It should be noted that one side of the driving magnet 120 is in contact with the magnetic force transmission component 130.
[0063] Preferably, a third mounting hole 110b is provided on the side of the disk body 110 away from the driving magnet 120, and the third mounting hole 110b is used for rotatable connection with an external magnetic drive structure.
[0064] In this embodiment, the external magnetic drive structure is rotatably connected to the disk body 110 through the third mounting hole 110b. That is, one end of the connecting shaft is rotatably connected to the third mounting hole 110b of the disk body 110. When the magnetic induction element generates a changing magnetic field, it acts on the magnetic conduction element 130. After being conducted by the magnetic conduction element 130, it directly acts on the driving magnet 120. Under the action of the changing magnetic field, the driving magnet 120 rotates around the positioning post 111, causing the disk body 110 to rotate together around the connecting shaft.
[0065] As the driving magnet 120 rotates, it can further drive the stir bar to rotate, so as to fully stir the powder or liquid in the accommodating cavity.
[0066] Because of the presence of the magnetic force transmission element 130, the magnetic force generated by the magnetic induction element is directly transmitted through the magnetic force transmission element 130 to the driving magnet 120, and then to the stir bar, so as to increase the rotation speed of the stir bar and improve the stirring effect of the stir bar.
[0067] Preferably, the driving magnet 120, the positioning post 111, and the receiving groove 110a form a sealed space.
[0068] Please refer to Figures 1-4 In this embodiment, since the driving magnet 120, the positioning post 111 and the receiving groove 110a form a sealed space, the magnetic force transmission component 130 can be more firmly installed in the receiving groove 110a, avoiding external components from affecting the magnetic force transmission component 130.
[0069] A stirring structure (not shown in the figure) includes a drive disk 100 as described in any of the above claims, the stirring structure further including:
[0070] A magnetic drive structure (not shown in the figure) includes a magnetic induction element (not shown in the figure) and a connecting shaft (not shown in the figure). The magnetic induction element is coupled to the drive disk 100, and the connecting shaft is rotatably connected to the drive disk 100.
[0071] The cup body (not shown in the figure) has a receiving cavity (not shown in the figure);
[0072] A stir bar (not shown in the figure) is housed in the accommodating cavity and coupled to the drive disk 100.
[0073] In this embodiment, during stirring, the magnetic induction element generates a changing magnetic field, which is directly transmitted to the driving magnet 120 through the magnetic force conduction element 130. The driving magnet 120 rotates under the action of the changing magnetic field, and the driving magnet 120 drives the disk 110 to rotate. Since the driving magnet 120 is coupled with the stir bar, the rotation of the driving magnet 120 drives the stir bar to rotate, thereby causing the stir bar to rotate in the accommodating cavity to stir the powder or liquid in the accommodating cavity.
[0074] Since the magnetic force conduction element 130 can directly apply the magnetic force of the magnetic induction element to the driving magnet 120, the magnetic force of the driving magnet 120 on the stir bar is stronger, thereby increasing the stirring speed of the stir bar and further increasing the stirring effect of the stir bar.
[0075] It should be noted that the magnetic induction element is a magnetic induction coil, the connecting shaft is a cylindrical rod, one end is fixed, and the other end is rotatably connected to the disc 110. The cup body is roughly a cylindrical shape with one side concave inward. The stirring bar is roughly a cylindrical magnetic block. The driving disc 100 is installed at the bottom of the cup body. The accommodating cavity is an open cavity, and the accommodating cavity is opened away from the bottom of the cup body.
[0076] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
