Description

Technical Field

[0001] This disclosure relates to the technical field of integrated magnetic coffee stirrers, and in particular to a magnetic stirring structure and an integrated magnetic coffee stirrer. Background Technology

[0002] In related technologies, coffee stirring cups typically consist of a magnetic coaster and a coffee cup. By placing a magnetic rotor into the coffee cup and then placing the cup on the predetermined position of the magnetic coaster, the coaster uses its magnetic field to attract the rotor, positioning it at the bottom of the cup and causing the rotor inside the cup to rotate, thus stirring the coffee. However, before stirring, the coffee cup needs to be precisely placed on the magnetic coaster, significantly reducing the convenience of using such coffee stirring cups. Furthermore, when the coffee cup is detached from the coaster, the coaster can no longer hold the rotor to the bottom of the cup, increasing the risk of accidentally swallowing the rotor while drinking coffee, thus greatly reducing the safety of using such coffee stirring cups. To solve these problems, further research and development of related technologies and equipment has been conducted.

[0003] Existing technology, such as patent CN219613555U, discloses a coffee cup with an automatic stirring function. It discloses a cup body with an inner shell fixedly connected to its inner wall. A magnetic stirring rod is placed at the bottom of the inner shell. A base is fixedly connected to the bottom of the cup body, and a micro motor is fixedly installed on the inner wall of the base. An output shaft is fixedly connected to the output end of the micro motor. A partition is fixedly connected to the inner wall of the base, and a rotating shaft is rotatably connected to the outer wall of the partition. The output shaft and the rotating shaft are connected via gear transmission. This automatic stirring function allows the coffee cup to stir without requiring the cup body to be placed in a predetermined position on the base, greatly improving ease of use. Simultaneously, when using the coffee cup, the magnet on the bottom plate can attract and hold the magnetic stirring rod to the bottom of the cup, reducing the probability of accidentally swallowing the magnetic stirring rod and significantly improving the safety of using the automatic stirring function coffee cup.

[0004] However, the magnetic stir bar of the aforementioned coffee cup is rod-shaped, resulting in low stirring efficiency. Furthermore, the stir bar only contains a first magnetic strip, leading to a weak magnetic force between the stir bar and the base plate magnet. When the base plate magnet moves the stir bar to stir the coffee, the stir bar encounters resistance from the liquid, causing the base plate to spin freely or even the stir bar to detach from the bottom of the cup, further reducing the stirring efficiency. Moreover, there is a risk of accidentally swallowing the stir bar while drinking coffee from this cup, compromising its safety. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a magnetic stirring structure and an integrated coffee magnetic stirring cup that can not only effectively improve stirring efficiency but also improve safety in use.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] A magnetic stirring structure, comprising:

[0008] The cup body has a stirring tank and a mounting cavity that are separated from each other;

[0009] A magnetic stirring rotor, wherein the magnetic stirring rotor is disposed in the stirring tank and rotatably connected to the bottom wall of the stirring tank;

[0010] A magnetic rotation assembly is installed and fixed in the mounting cavity, and the magnetic rotation end of the magnetic rotation assembly is arranged opposite to the magnetic stirring rotor and magnetically attracted to each other.

[0011] The magnetic stirring rotor includes a rotor body and three stirring blades. The first ends of the three stirring blades are fixedly connected to the outer periphery of the rotor body, and the second end of each stirring blade is provided with a first permanent magnet. The magnetic rotation end of the magnetic rotation assembly is provided with three second permanent magnets. The first permanent magnets of the three stirring blades and the three second permanent magnets are arranged in a one-to-one correspondence and are magnetically attracted to each other.

[0012] In one embodiment, the first ends of the three stirring paddles are evenly arranged along the outer periphery of the rotor body, so that the magnetic stirring rotor is gear-shaped.

[0013] In one embodiment, rotating flanges are provided on both sides of the rotor body so that the height of both sides of the rotor body is greater than that of each of the stirring blades.

[0014] In one embodiment, the magnetic stirring rotor is divided into an upper rotor cover and a lower rotor cover. The upper rotor cover is fixedly connected to the lower rotor cover to form the magnetic stirring rotor together. The upper rotor cover has a first receiving groove, and the lower rotor cover has a second receiving groove. The upper rotor cover and the lower rotor cover are arranged opposite to each other so that the first receiving groove and the second receiving groove together form a receiving cavity. The first permanent magnet is installed and fixed in the receiving cavity.

[0015] In one embodiment, the magnetic rotation assembly includes a motor and a rotating disk. The motor is installed and fixed in the mounting cavity, and the power output end of the motor is fixedly connected to the rotating disk. The second permanent magnet is disposed on the rotating disk.

[0016] In one embodiment, a cup liner is installed and fixed inside the cup body, so that the cup body forms the mutually separated mounting cavity and the stirring tank.

[0017] In one embodiment, the inner cup is formed with the stirring groove.

[0018] In one embodiment, the magnetic rotation assembly further includes a bracket, which is installed and fixed inside the mounting cavity, and both the cup liner and the magnetic rotation assembly are installed and fixed on the bracket.

[0019] In one embodiment, the rotating disk has three fixing slots, and each second permanent magnet is installed and fixed in the corresponding fixing slot.

[0020] In one embodiment, the magnetic rotation assembly further includes a motor pressure plate, which is disposed between the motor and the bracket. The motor pressure plate is fixedly connected to both the motor and the bracket to mount and fix the motor onto the bracket.

[0021] In one embodiment, the rotor top cover is ultrasonically bonded to the rotor bottom cover.

[0022] An integrated magnetic coffee stirrer includes the magnetic stirring structure described in any of the above embodiments.

[0023] Compared with the prior art, this disclosure has at least the following advantages:

[0024] 1. In the above-mentioned magnetic stirring structure, the magnetic stirring rotor includes a rotor body and three stirring blades. The first ends of the three stirring blades are all fixedly connected to the outer periphery of the rotor body, so as to increase the contact area between the magnetic stirring rotor and the coffee liquid, thereby greatly improving the stirring efficiency of the above-mentioned magnetic stirring structure.

[0025] 2. Since each stirring paddle is equipped with a first permanent magnet at its second end, and the magnetic rotating end of the magnetic rotation assembly is equipped with three second permanent magnets, the first permanent magnets of the three stirring paddles and the three second permanent magnets are arranged in a one-to-one correspondence and are magnetically attracted to each other. This greatly enhances the magnetic attraction between the magnetic stirring rotor and the magnetic rotating end of the magnetic rotation assembly, allowing the magnetic stirring rotor to be more securely positioned and attracted to the bottom wall of the stirring tank through the magnetic rotating end of the magnetic rotation assembly. Furthermore, this allows the magnetic rotating end of the magnetic rotation assembly to better drive the magnetic stirring rotor to rotate relative to the cup body, preventing the magnetic rotating end of the magnetic rotation assembly from spinning freely when stirring coffee. It also prevents the magnetic stirring rotor from detaching from the bottom wall of the stirring tank when stirring coffee. This not only further improves the stirring efficiency of the magnetic stirring structure but also prevents accidental swallowing of the magnetic stirring rotor when drinking coffee using the magnetic stirring structure, greatly improving the safety of the magnetic stirring structure.

[0033] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0034] like Figures 1 to 3 As shown, a magnetic stirring structure 100 of one embodiment includes a cup body 110, a magnetic stirring rotor 120, and a magnetic rotation assembly 130. The cup body 110 has a stirring groove 111 and a mounting cavity 112 that are separated from each other. The magnetic stirring rotor 120 is disposed in the stirring groove 111 and is rotatably connected to the bottom wall of the stirring groove 111. The magnetic rotation assembly 130 is installed and fixed in the mounting cavity 112. The magnetic rotation end of the magnetic rotation assembly 130 is disposed opposite to the magnetic stirring rotor 120 and magnetically attracted to each other, so that when stirring coffee, the magnetic rotation end of the magnetic rotation assembly 130 can drive the magnetic stirring rotor 120 to rotate relative to the cup body 110, so that the magnetic stirring rotor 120 can stir the coffee in the stirring groove 111.

[0035] like Figures 1 to 3As shown, the magnetic stirring rotor 120 further includes a rotor body 121 and three stirring blades 122. The first ends of the three stirring blades 122 are all fixedly connected to the outer periphery of the rotor body 121, thereby increasing the contact area between the magnetic stirring rotor 120 and the coffee liquid, and thus greatly improving the stirring efficiency of the magnetic stirring structure 100. Furthermore, each stirring blade 122 has a first permanent magnet 123 at its second end, and the magnetic rotation end of the magnetic rotation assembly 130 has three second permanent magnets 131. The first permanent magnets 123 and the three second permanent magnets 131 of the three stirring blades 122 are arranged in a one-to-one correspondence and are magnetically attracted to each other, thereby greatly increasing the magnetic attraction between the magnetic stirring rotor 120 and the magnetic rotation end of the magnetic rotation assembly 130, thus improving the magnetic stirring efficiency of the magnetic stirring rotor 120. The magnetic rotating end of the magnetic rotating component 130 can be more securely positioned and adsorbed onto the bottom wall of the stirring tank 111, and the magnetic rotating end of the magnetic rotating component 130 can better drive the magnetic stirring rotor 120 to rotate relative to the cup body 110. This avoids the phenomenon of the magnetic rotating end of the magnetic rotating component 130 spinning freely when the magnetic stirring structure 100 is stirring coffee, and also avoids the phenomenon of the magnetic stirring rotor 120 detaching from the bottom wall of the stirring tank 111 when the magnetic stirring structure 100 is stirring coffee. This not only further improves the stirring efficiency of the magnetic stirring structure 100, but also avoids the situation of accidentally swallowing the magnetic stirring rotor 120 when drinking coffee using the magnetic stirring structure 100, greatly improving the safety of using the magnetic stirring structure 100.

[0036] In this embodiment, when it is necessary to stir the coffee in the stirring tank 111, firstly, the magnetic stirring rotor 120 is placed in the stirring tank 111. The magnetic stirring rotor 120 is positioned and attracted to the bottom wall of the stirring tank 111 by the magnetic attraction between the first permanent magnet 123 and the second permanent magnet 131. Then, coffee powder and water are poured into the stirring tank 111. Next, the magnetic rotation assembly 130 is turned on, and the magnetic rotating end of the magnetic rotation assembly 130 can rotate relative to the cup body 110. The magnetic attraction between the second permanent magnet 131 and the first permanent magnet 123 drives the magnetic stirring rotor 120 to rotate relative to the cup body 110, so that the magnetic stirring rotor 120 can stir and mix the coffee powder and water in the stirring tank 111. Finally, after the coffee in the stirring tank 111 has been stirred, the magnetic rotation assembly 130 is turned off.

[0037] The magnetic stirring structure 100 described above includes a magnetic stirring rotor 120 comprising a rotor body 121 and three stirring blades 122. The first ends of the three stirring blades 122 are all fixedly connected to the outer periphery of the rotor body 121, thereby increasing the contact area between the magnetic stirring rotor 120 and the coffee liquid, and thus greatly improving the stirring efficiency of the magnetic stirring structure 100 described above.

[0038] Furthermore, since each stirring paddle 122 is equipped with a first permanent magnet 123 at its second end, and the magnetic rotation end of the magnetic rotation assembly 130 is equipped with three second permanent magnets 131, the first permanent magnets 123 and the three second permanent magnets 131 of the three stirring paddles are arranged in a one-to-one correspondence and are magnetically attracted to each other. This greatly enhances the magnetic attraction between the magnetic stirring rotor 120 and the magnetic rotation end of the magnetic rotation assembly 130, allowing the magnetic stirring rotor 120 to be more securely positioned and attracted to the bottom wall of the mixing tank 111 through the magnetic rotation end of the magnetic rotation assembly 130. This also allows the magnetic rotation end of the magnetic rotation assembly 130 to... This allows for better rotation of the magnetic stirring rotor 120 relative to the cup body 110, preventing the magnetic rotating end of the magnetic rotating component 130 from spinning freely when stirring coffee. It also prevents the magnetic stirring rotor 120 from detaching from the bottom wall of the stirring tank 111 when stirring coffee. This not only further improves the stirring efficiency of the magnetic stirring structure 100, but also prevents accidental swallowing of the magnetic stirring rotor 120 when drinking coffee using the magnetic stirring structure 100, greatly improving the safety of using the magnetic stirring structure 100.

[0039] like Figures 1 to 3 As shown, in one embodiment, the first ends of the three stirring blades 122 are evenly arranged along the outer periphery of the rotor body 121 so that the magnetic stirring rotor 120 is gear-shaped, thereby improving the stirring effect of the magnetic stirring structure 100.

[0040] like Figure 2 and Figure 3 As shown, in one embodiment, rotating flanges 121a are provided on both sides of the rotor body 121 so that the height of both sides of the rotor body 121 is greater than that of both sides of each stirring paddle 122. This reduces the contact area between the magnetic stirring rotor 120 and the bottom wall of the stirring tank 111 when the magnetic stirring structure 100 stirs coffee, greatly reducing the resistance experienced by the magnetic stirring rotor 120 when rotating relative to the cup body 110, and thus greatly reducing the probability of the magnetic stirring structure 100 spinning idly. At the same time, it can also reduce the noise generated by the friction between the magnetic stirring rotor 120 and the bottom wall of the stirring tank 111.

[0041] like Figure 2As shown, in one embodiment, the magnetic stirring rotor 120 is divided into an upper rotor cover 124 and a lower rotor cover 125. The upper rotor cover 124 is fixedly connected to the lower rotor cover 125 to form the magnetic stirring rotor 120 together. The upper rotor cover 124 has a first receiving groove 124a, and the lower rotor cover 125 has a second receiving groove 125a. The upper rotor cover 124 and the lower rotor cover 125 are arranged opposite to each other so that the first receiving groove 124a and the second receiving groove 125a together form a receiving cavity 126. The first permanent magnet 123 is installed and fixed in the receiving cavity 126, which greatly reduces the difficulty of installing and fixing the first permanent magnet 123 into the receiving cavity 126, thereby reducing the assembly difficulty of the magnetic stirring structure 100 and improving the production efficiency of the magnetic stirring structure 100.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the magnetic rotation assembly 130 includes a motor 132 and a rotating disk 133. The motor 132 is installed and fixed in the mounting cavity 112. The power output end of the motor 132 is fixedly connected to the rotating disk 133. A second permanent magnet 131 is disposed on the rotating disk 133 so that the motor 132 can drive the rotating disk 133 to rotate relative to the cup body 110. The rotating disk 133 can drive the first permanent magnet 123 in the magnetic stirring rotor 120 to rotate relative to the cup body 110 through the second permanent magnet 131, so that the rotating disk 133 can drive the magnetic stirring rotor 120 to rotate relative to the cup body 110, thereby enabling the motor 132 to drive the magnetic stirring rotor 120 to stir the coffee in the stirring tank 111.

[0043] like Figure 1 As shown, in one embodiment, a cup liner 113 is installed and fixed inside the cup body 110, so that the cup body 110 forms a mutually separated mounting cavity 112 and stirring groove 111, preventing coffee in the stirring groove 111 from entering the mounting cavity 112 when the magnetic stirring structure 100 is stirring coffee, thereby improving the safety of the use of the magnetic stirring structure 100.

[0044] like Figure 1 As shown, in one embodiment, the inner cup 113 is formed with a stirring tank 111 so that the coffee in the stirring tank 111 can maintain its original temperature for a longer period of time.

[0045] like Figures 1 to 2 As shown, in one embodiment, the magnetic rotation assembly 130 further includes a bracket 134, which is installed and fixed in the mounting cavity 112. The inner cup 113 and the magnetic rotation assembly 130 are both installed and fixed on the bracket 134 to prevent the inner cup 113 and the magnetic rotation assembly 130 from deviating from their predetermined positions due to shaking when stirring coffee.

[0046] like Figure 2 and Figure 3 As shown, in one embodiment, the rotating disk 133 is provided with a fixing groove 133a. There are three fixing grooves 133a. Each second permanent magnet 131 is installed and fixed in the corresponding fixing groove 133a. This is to prevent the second permanent magnet 131 on the rotating disk 133 from detaching from the rotating disk 133 due to excessive centrifugal force when the rotating disk 133 is rotating at an accelerated speed. This extends the service life of the magnetic stirring structure 100.

[0047] like Figure 2 As shown, in one embodiment, the magnetic rotation assembly 130 further includes a motor pressure plate 135, which is disposed between the motor 132 and the bracket 134. The motor pressure plate 135 is fixedly connected to the motor 132 and the bracket 134 respectively, so as to install and fix the motor 132 on the bracket 134 to ensure that the motor 132 can be stably positioned at a preset position during use.

[0048] like Figure 2 As shown, in one embodiment, the rotor upper cover 124 is ultrasonically bonded to the rotor lower cover 125 so that the rotor upper cover 124 can be securely fixed to the rotor lower cover 125.

[0049] This disclosure also provides an integrated coffee magnetic stirring cup 10, including the magnetic stirring structure 100 described in any of the above embodiments.

[0050] Compared with the prior art, this disclosure has at least the following advantages:

[0051] 1. The aforementioned integrated magnetic coffee stirrer 10, since the magnetic stirring rotor 120 includes a rotor body 121 and stirring paddles 122, and the number of stirring paddles 122 is three, the first ends of the three stirring paddles 122 are all fixedly connected to the outer periphery of the rotor body 121, so as to increase the contact area between the magnetic stirring rotor 120 and the coffee liquid, thereby greatly improving the stirring efficiency of the aforementioned magnetic stirring structure 100.

[0052] 2. Since each stirring paddle 122 is equipped with a first permanent magnet 123 at its second end, and the magnetic rotation end of the magnetic rotation assembly 130 is equipped with three second permanent magnets 131, the first permanent magnets 123 and the three second permanent magnets 131 of the three stirring paddles 122 are arranged in a one-to-one correspondence and are magnetically attracted to each other. This greatly enhances the magnetic attraction between the magnetic stirring rotor 120 and the magnetic rotation end of the magnetic rotation assembly 130, allowing the magnetic stirring rotor 120 to be more securely positioned and attracted to the bottom wall of the mixing tank 111 through the magnetic rotation end of the magnetic rotation assembly 130. Furthermore, this allows the magnetic rotation end of the magnetic rotation assembly 130 to... This allows for better rotation of the magnetic stirring rotor 120 relative to the cup body 110, preventing the magnetic rotating end of the magnetic rotating component 130 from spinning freely when stirring coffee. It also prevents the magnetic stirring rotor 120 from detaching from the bottom wall of the stirring tank 111 when stirring coffee. This not only further improves the stirring efficiency of the magnetic stirring structure 100, but also prevents accidental swallowing of the magnetic stirring rotor 120 when drinking coffee using the magnetic stirring structure 100, greatly improving the safety of using the magnetic stirring structure 100.

[0053] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
