Description

Technical Field

[0001] This utility model relates to the field of stirring cup technology, specifically to a wear-resistant magnetic stirring cup. Background Technology

[0002] Cups are essential for daily drinking. When using cups to drink at home, in the office, or while traveling, stirring is sometimes necessary, such as stirring coffee, milk tea, making milk, beating eggs, preparing beverages, or drinking oatmeal. The usual method is to use a spoon or chopsticks, which is cumbersome and results in uneven mixing. To address this, a new type of stirring cup has emerged, where the stirring motor is placed at the bottom of the cup. The motor's output shaft extends upwards from the bottom of the cup and enters the cup body to drive the stirrer. However, due to sealing issues between the motor's output shaft and the bottom of the cup, liquid or the material being stirred can easily seep into the bottom of the cup along the gap between the shafts, causing corrosion to the stirring motor. Furthermore, cleaning the stirrer and the bottom of the cup is extremely inconvenient, easily leading to the accumulation of dirt on the stirrer and the bottom of the cup, affecting hygiene.

[0003] In light of the above, magnetic stirring cups have emerged. For example, Chinese utility model patent No. 202120658614.4 (publication No. CN215687155U) disclosed "A Magnetic Stirring Cup," which includes a cup body and a stirrer. The stirrer includes a stirring driver and a magnetic stirring rotor. The stirring driver is located outside the cup body and includes a housing, a power module, a stirring motor, and a magnetic rotating component. The power module, stirring motor, and magnetic rotating component are all installed in the housing. The power module is electrically connected to the stirring motor. The middle part of the magnetic rotating component is mounted on the output shaft of the stirring motor, and the magnetic poles at both ends of the magnetic rotating component are in opposite directions. The magnetic stirring rotor is located inside the cup body, and the magnetic poles at both ends of the magnetic stirring rotor are in opposite directions. The corresponding ends of the magnetic rotating component and the magnetic stirring rotor attract each other. This magnetic stirring cup can stir powders and hot water in the cup, is easy to clean, and effectively protects the stirring motor.

[0004] However, these magnetic stirring cups also have problems. Because the magnetic rotating parts usually rotate at high speed during stirring, and the cup body is usually made of plastic to control costs, the magnetic rotating parts will rub against the bottom wall of the plastic cup body during high-speed operation, causing the bottom wall of the cup body to be worn and producing plastic shavings, which will affect people's health.

[0005] Therefore, how to provide a magnetic stirring cup that can effectively prevent the cup body from being worn and generating harmful debris is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a wear-resistant magnetic stirring cup that can effectively prevent the cup body from being worn and generating harmful debris, in light of the above-mentioned existing technology.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the wear-resistant magnetic stirring cup includes a cup body, a stirring rotor built into the cup body, and a magnetic drive device located at the bottom of the cup body for driving the stirring rotor to rotate. The inner bottom of the cup body is composited with a wear-resistant metal layer, and the wear-resistant metal layer can cover the rotation trajectory area of ​​the stirring rotor at the bottom of the cup body.

[0008] To avoid gaps at the connection between the wear-resistant metal layer and the inner wall of the cup, which could lead to dirt buildup, and to make cleaning the cup easier, preferably, the outer edge of the wear-resistant metal layer is bent upwards and forms a smooth connection with the inner wall of the cup.

[0009] In order to better bond the wear-resistant metal layer with the cup body and save manufacturing costs, preferably, the wear-resistant metal layer is a metal insert and is integrally formed with the cup body during manufacturing.

[0010] In order to enable the stirring rotor to better accommodate two magnetic blocks with opposite magnetic poles at the same time, preferably, the stirring rotor includes two symmetrically distributed stirring parts in a roughly elliptical shape. The two stirring parts are connected to each other, and a spherical protrusion is formed at the connection point, which is exposed on the upper end face and / or the lower end face of the stirring rotor and can contact the wear-resistant metal layer. The two stirring parts contain magnetic blocks with opposite magnetic poles.

[0011] In order to ensure that the two stirring parts can maintain good smoothness and stability when rotating at high speed, preferably, the two sides of the stirring rotor are respectively connected to semi-annular connecting parts, and the two ends of each connecting part are respectively connected to the sides of the two stirring parts.

[0012] To better accommodate the magnetic drive device, preferably, a cup holder is also included, on which the cup body is detachably mounted. The magnetic drive device is mounted on the cup holder and corresponds to the stirring rotor to drive the stirring rotor to rotate.

[0013] In order to enable the cup body to be detachably connected to the cup holder, preferably, the bottom of the cup body has a downward-facing mounting cavity, the cup holder has a mounting part that can extend into the mounting cavity, the inner peripheral wall of the mounting cavity has a snap-fit ​​part, and the outer peripheral wall of the mounting part has a snap-fit ​​groove for snap-fit ​​adaptation of the snap-fit ​​part.

[0014] To optimize the detachable structure between the cup body and the cup holder, allowing the cup body and the cup holder to quickly engage or disengage by rotating relative to each other, preferably, the engaging groove is formed circumferentially on the outer peripheral wall of the mounting part, and the engaging part includes at least two engaging blocks arranged circumferentially on the inner peripheral wall of the mounting cavity. When the cup holder and the cup body are rotating relative to each other circumferentially, the cup body can be detachably connected to the cup holder by engaging or disengaging the engaging part and the engaging groove.

[0015] In order to enable the cup body and cup seat to be quickly positioned after being snapped together, preferably, at least one of the snapping blocks is arc-shaped and elastic, and an arc-shaped groove adapted to the arc-shaped snapping block is formed on the groove wall that contacts the snapping part.

[0016] Compared with the prior art, the advantages of this utility model are as follows: by laminating a wear-resistant metal layer to the inner bottom of the cup body, and ensuring that this wear-resistant metal layer covers the rotation trajectory area of ​​the stirring rotor at the bottom of the cup body, and ensuring that the hardness of this wear-resistant metal layer is greater than that of the cup body material, the working surface that rubs against the stirring rotor at high speed is always a highly wear-resistant metal layer rather than the plastic inner wall of the cup body itself. This effectively solves the drawback of the prior art where harmful debris is generated inside the cup body due to the wear of the bottom of the cup body by the stirring rotor, thus ensuring the quality of the stirred liquid and extending the service life of the stirring cup.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Figures 1-6 A preferred embodiment of the wear-resistant magnetic stirring cup shown.

[0025] The wear-resistant magnetic stirring cup of this embodiment includes a main cup body 1, a stirring rotor 2, a magnetic drive device 3, a wear-resistant metal layer 4, and a cup base 5, etc.

[0026] refer to Figures 1 to 3 As shown, the stirring rotor 2 is built into the cup body 1, and the magnetic drive device 3 is set at the bottom of the cup body 1 to drive the stirring rotor 2 to rotate and achieve stirring. The inner bottom of the cup body 1 is coated with a wear-resistant metal layer 4, and the wear-resistant metal layer 4 can cover the rotation trajectory area of ​​the stirring rotor 2 at the bottom of the cup body 1. The hardness of the wear-resistant metal layer 4 is usually greater than the hardness of the cup body 1 material and forms a fixed connection with the cup body 1.

[0027] In order to avoid the formation of dirt due to gaps at the connection between the wear-resistant metal layer 4 and the inner wall of the cup body 1, reference is made to... Figure 3 As shown, in this embodiment, the outer edge of the wear-resistant metal layer 4 is deliberately bent upwards and smoothly connected to the inner wall of the cup body 1. This design not only further protects the transition area between the inner wall of the cup body 1 and the wear-resistant metal layer 4, but also reduces liquid residue during stirring and makes the cup body 1 easier to clean quickly.

[0028] Secondly, in order to better bond the wear-resistant metal layer 4 with the cup body 1, and to further reduce manufacturing costs, refer to... Figure 3 As shown, when making the cup body 1, the pre-made wear-resistant metal layer 4 is placed into the mold as a metal insert. Then, the cup body 1 and the wear-resistant metal layer 4 are integrally formed by injection molding and other processes. It is also ensured that the outer edge of the wear-resistant metal layer 4 is bent upward and forms a smooth connection with the inner bottom wall of the cup body 1. It is also ensured that the wear-resistant metal layer 4 can cover the rotation trajectory area of ​​the stirring rotor 2 at the bottom of the cup body 1. This integral forming method makes the connection between the wear-resistant metal layer 4 and the cup body 1 more solid, thereby improving the overall performance and stability of the cup body 1.

[0029] Furthermore, in order for the stirring rotor 2 here to better accommodate two magnetic blocks 2c with opposite magnetic poles simultaneously, refer to Figure 5 and Figure 6 As shown, in this embodiment, the stirring rotor 2 includes two symmetrically distributed, elliptical stirring sections 2a. The two stirring sections 2a are connected to each other, and at the connection point, a spherical protrusion 2b is formed that is exposed on the upper end face and / or the lower end face of the stirring rotor 2 and can contact the wear-resistant metal layer 4. The spherical protrusion 2b can be provided only on the upper end face or the lower end face of the stirring rotor 2, or it can be provided on both the upper and lower end faces of the stirring rotor 2. In addition, magnetic blocks 2c with opposite magnetic pole directions are respectively provided inside the two stirring sections 2a.

[0030] Meanwhile, in order to ensure that the two stirring sections 2a here can maintain good smoothness and stability during high-speed rotation, refer to Figure 5 As shown, semi-annular connecting parts 2d are specially connected to the opposite sides of the stirring rotor 2, and the two ends of each connecting part 2d are respectively connected to the sides of the two stirring parts 2a.

[0031] Through the special structural design of the stirring rotor 2, the stirring rotor 2 can rotate stably under the action of the magnetic drive device 4. At the same time, the contact method between the spherical protrusion 2b and the wear-resistant metal layer 4 further reduces the friction on the wear-resistant metal layer 4 and improves the stirring efficiency.

[0032] In this embodiment, in order to better install the magnetic drive device 3, refer to Figures 1 to 3 As shown, this embodiment also includes a cup holder 5, on which the cup body 1 is detachably mounted. A magnetic drive device 3 is mounted on the cup holder 5 and corresponds to the stirring rotor 2 to drive the stirring rotor 2 to rotate. The magnetic drive device 3 is prior art and will not be described in detail here.

[0033] In this embodiment, in order to optimize the disassembly structure between the cup body 1 and the cup base 5, and to enable the cup body 1 and the cup base 5 to quickly engage or disassemble by rotating relative to each other, reference is made. Figures 2 to 4 As shown, the bottom of the cup body 1 has a downward-facing mounting cavity 1a, and the cup seat 5 has a mounting part 5a that can extend into the mounting cavity 1a. The inner peripheral wall of the mounting cavity 1a has a snap-fit ​​part 1b, and the outer peripheral wall of the mounting part 5a has a snap-fit ​​groove 5b for snap-fit ​​adaptation of the snap-fit ​​part 1b.

[0034] refer to Figure 2 and Figure 4 As shown, in order to optimize the detachable structure between the cup body 1 and the cup holder 5, and to enable the cup body 1 and the cup holder 5 to quickly engage or disengage by rotating relative to each other, in this embodiment, the engaging groove 5b is formed circumferentially on the outer peripheral wall of the mounting part 5a, and the engaging part 1b includes at least two engaging blocks 1b1 arranged circumferentially on the inner peripheral wall of the mounting cavity 1a. When the cup holder 5 and the cup body 1 are rotating relative to each other circumferentially, the cup body 1 can be detachably connected to the cup holder 5 by engaging or disengaging the engaging part 1b and the engaging groove 5b. The attached figure shows three engaging blocks 1b1, but we can also set more or fewer.

[0035] In addition, to ensure that the cup body 1 and the cup base 5 can be quickly positioned after they are snapped together, refer to Figure 2 and Figure 4 As shown, the locking block 1b1 located in the middle is specially made to be arc-shaped and have a certain elasticity. At the same time, an arc-shaped groove 5b1 adapted to the arc-shaped locking block 1b1 is formed on the groove wall where the locking groove 5b contacts the locking part 1b.

[0036] The specific installation and disassembly process of the cup body 1 and the cup holder 5 is as follows: First, align the mounting cavity 1a at the bottom of the cup body 1 with the mounting part 5a on the cup holder 5, so that the mounting part 5a extends into the mounting cavity 1a. Then, rotate the cup holder 5 or the cup body 1 in the circumferential direction so that the locking block 1b1 on the inner circumferential wall of the mounting cavity 1a engages in the locking groove 5b on the outer circumferential wall of the mounting part 5a. At the same time, the arc-shaped and elastic 1b1 fits into the arc-shaped groove 5b1 to achieve positioning, thereby achieving a stable connection between the cup body 1 and the cup holder 5. When disassembly is required, apply a little force to rotate the cup holder 5 or the cup body 1 in the opposite direction so that the locking block 1b1 disengages from the locking groove 5b, and the cup body 1 can be quickly removed from the cup holder 1.

[0037] It is also necessary to further explain that in this embodiment, a wear-resistant metal layer 4 is laminated to the inner bottom of the cup body 1, and this wear-resistant metal layer 4 covers the rotation trajectory area of ​​the stirring rotor 2 at the bottom of the cup body 1. The hardness of this wear-resistant metal layer 41 is greater than that of the cup body material. This ensures that when the stirring rotor 2 rotates at high speed, the working surface that rubs against it is always the highly wear-resistant metal layer 4, rather than the plastic inner wall of the cup body 1 itself. This effectively solves the drawback of the prior art where harmful debris is generated inside the cup body due to the wear of the bottom of the cup body by the stirring rotor. This not only ensures the quality of the stirred liquid but also extends the service life of the stirring cup. Through the above specific implementation method, the wear-resistant magnetic stirring cup in this embodiment can achieve efficient and stable stirring function, while effectively solving the problem of easy wear at the bottom of the cup body 1, improving the practicality of the product and the user experience.
