Description

Technical Field

[0001] Some embodiments of this utility model relate to a milk frother, and more particularly to a control device for a milk frother generator and a milk frother. Background Technology

[0002] A milk frother uses a device that generates eddies in liquid milk by adding it to various liquid storage containers. The device continuously stirs the liquid milk in the storage containers and filters, cuts and heats the liquid milk during stirring to produce milk foam.

[0003] Currently, some milk frothers use magnetic attachment to fix the milk frother inside the milk frother's container, allowing the drive assembly to rotate the frother's blades and create milk foam. However, the inventors discovered that during rotation, the frother's inertia and the magnetic force between it and the drive assembly often disrupt the magnetic coupling, causing the magnetic connection to fail. This results in the milk frother being unable to stably froth the liquid milk in the container, and in severe cases, the entire frother may detach from its target position within the container. Utility Model Content

[0004] The purpose of this utility model embodiment is to design a control device and a milk frother for a milk frother, which can effectively improve the stability of the milk frother when foaming liquid milk and prevent the milk frother from falling out of the target position in the liquid storage container due to magnetic failure when foaming liquid milk.

[0005] To achieve the above objectives, some embodiments of this utility model provide a control device for a milk frother, used to control the drive assembly of the milk frother, causing the drive assembly to drive the paddle component of the milk frother, which is magnetically coupled to it, to rotate. The control device includes: A detection module is used to detect the rotational speed and input voltage of the drive component; The main control module is communicatively connected to the detection module and is used to acquire the input voltage and rotational speed measured by the detection module. The main control module is further configured to output a deceleration signal to the drive component when the rotational speed under any input voltage is greater than any rotational speed in the target rotational speed range, so that the rotational speed of the drive component is reduced to a preset speed less than the current rotational speed.

[0006] In addition, some embodiments of this utility model also provide a milk frother, including: A base for detachably mounting the liquid storage container; A milk frother is detachably placed inside the liquid storage container; the milk frother includes: a flow-turbulence component and a paddle component rotatably disposed within the flow-turbulence component; The drive assembly is mounted on the base. A positioning component is used to position the turbulence-disrupting component at a target location within the liquid storage container; A magnetic coupling assembly is used to magnetically couple the blade component to the drive assembly when the turbulence component is positioned at a target location within the liquid storage container. The control device described above; The drive component is used to receive the deceleration signal output by the detection module, and to reduce the rotational speed to a preset speed lower than the current rotational speed after receiving the deceleration signal.

[0007] Compared to the prior art, the embodiments of this utility model, when the drive component of the milk frother is driving the milk frother to foam the liquid in the storage container, can have its rotational speed and input voltage detected in real time by the detection module. The main control module can obtain the rotational speed and input voltage measured by the detection module. When the rotational speed of the main control module at any input voltage is greater than any rotational speed in the target rotational speed range, it indicates that the magnetic attraction between the paddle component of the milk frother and the drive component has been destroyed. At this time, the main control module can output a deceleration signal to the drive component, so that the drive component can reduce its rotational speed to a preset speed lower than the current rotational speed after receiving the deceleration signal. This helps to re-establish a stable magnetic attraction between the paddle component and the drive component, so that the user does not need to remove the milk frother or pour out the liquid milk. This not only avoids contamination of the liquid milk, but also effectively improves the stability of the milk frother when foaming liquid milk, and avoids the phenomenon that the milk frother will detach from the target position in the storage container due to the failure of magnetic attraction when foaming liquid milk.

Detailed Implementation

[0009] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0010] Example 1 Embodiment 1 of this utility model relates to a control device for a milk frothing generator, such as... Figure 8 and Figure 3 As shown, the control device 8 is used to control the drive assembly 4 of the milk frother, causing the drive assembly 4 to drive the paddle component 12 of the milk frother 1, which is magnetically coupled to it, to rotate. Furthermore, as... Figure 8 As shown, the control device 8 includes a detection module 81 and a main control module 82.

[0011] Among them, combined Figure 8 As shown, both the detection module 81 and the main control module 82 are mounted on the base 3 of the milk frother. The detection module 81 detects the rotational speed and input voltage of the drive component 4, while the main control module 82 is communicatively connected to the detection module 81. Furthermore, the main control module 82 acquires the input voltage and rotational speed measured by the detection module 81, and when the rotational speed at any input voltage exceeds any speed within the target rotational speed range, it outputs a deceleration signal to the drive component 4, reducing the rotational speed of the drive component 4 to a preset speed lower than the current speed.

[0012] From the above, it is clear that when the drive component 4 of the milk frother drives the milk frother 1 to foam the liquid in the storage container 2, the detection module 81 can detect the rotation speed and input voltage of the drive component 4 in real time. The main control module 82 can obtain the rotation speed and input voltage measured by the detection module 81. When the rotation speed of the main control module 82 at any input voltage is greater than any rotation speed in the target rotation speed range, it indicates that the magnetic attraction effect between the paddle component 12 of the milk frother and the drive component 4 is broken. At this time, the main control module 82 can send a signal to the drive component 4. Component 4 outputs a deceleration signal, which enables the drive component 4 to reduce its rotation speed to a preset speed lower than the current speed after receiving the deceleration signal. This helps to re-establish a stable magnetic attraction between the paddle component 12 and the drive component 4, so that the user does not need to remove the milk frothing device or pour out the liquid milk. This not only avoids contamination of the liquid milk, but also effectively improves the stability of the milk frothing generator 1 when frothing liquid milk. It also prevents the milk frothing generator 1 from detaching from the target position in the liquid storage container 2 due to magnetic attraction failure when frothing liquid milk.

[0013] Specifically, during operation, the milk frother 1 may be impacted by the pouring of liquid milk and / or powder, potentially disrupting the magnetic attraction between the paddle component 12 and the drive assembly 4. Once this magnetic attraction is disrupted, the rotational speed of the drive assembly 4 gradually increases. However, when the magnetic attraction between the paddle component 12 and the drive assembly 4 is stable, the drive assembly 4, due to the load, will rotate at a much lower speed than when the magnetic attraction was disrupted. For example, when the magnetic attraction between the blade component 12 and the drive assembly 4 is not disrupted, the drive assembly 4 rotates at a speed of 3000 r / min to 5000 r / min due to the presence of the load. However, when the magnetic attraction between the blade component 12 and the drive assembly 4 is disrupted, the drive assembly 4 is disconnected from the load, causing its speed to increase instantaneously. Generally, the speed of the drive assembly 4 will increase instantaneously to 8000 r / min to 9000 r / min. Therefore, an adjustable target speed range can be pre-stored in the main control module 82. For example, the target speed range can be set to 2000 r / min-5000 r / min, generally not exceeding 8000 r / min. Therefore, once the speed of the drive component 4 measured by the detection module 81 is greater than the target speed range, it indicates that the magnetic attraction between the drive component 4 and the blade component 12 is destroyed. At this time, the main control module 82 can output a deceleration signal to the drive component 4, so that the speed of the drive component 4 can be reduced to a preset speed lower than the current speed. By reducing the speed of the drive component 4, a stable magnetic attraction can be re-established between the blade component 12 and the drive component 4, thereby effectively improving the stability of the milk frother 1 when foaming liquid milk.

[0014] In addition, it is worth mentioning that when the speed of the drive component 4 is reduced to a preset speed lower than the current speed, it can help the blade component 12 and the drive component 4 to re-establish magnetic attraction. When the blade component 12 and the drive component 4 re-establish magnetic attraction, the speed of the drive component 4 will be instantly reduced to a preset speed lower than the current speed due to the presence of the load. Furthermore, it is not difficult to see from the above that after the magnetic attraction between the blade component 12 and the drive component 4 is broken, the rotation speed of the blade component 12 will instantly increase to 8000 r / min to 9000 r / min. Therefore, when setting the preset rotation speed, the preset rotation speed should be less than 8000 r / min. For example, the preset rotation speed can be set to 1500 r / min. When the drive component 4 is at this preset rotation speed, if the magnetic attraction between the drive component 4 and the blade component 12 is restored, the rotation speed of the drive component 4 will be further reduced due to the presence of the load. Therefore, when the rotation speed of the drive component 4 is reduced to the preset rotation speed, if the rotation speed obtained by the main control module 82 within the preset time is less than the preset rotation speed, it means that the drive component 4 and the blade component 12 have restored the magnetic attraction. At this time, the main control module 82 can output an acceleration signal to the drive component 4, so that the rotation speed of the drive component 4 can be gradually increased to the target rotation speed greater than the preset rotation speed, so that the milk frother 1 can continue to frother the liquid milk in the storage container 2.

[0015] Furthermore, as a preferred embodiment, in other embodiments, such as Figure 8 As shown, the control device 8 also includes an alarm module 83, which is also connected to the main control module 82. Therefore, when the speed of the drive component 4 is reduced to the preset speed, the main control module 82 is also used to output an alarm signal to the alarm module 83 when the speed obtained for the first time or continuously within a preset time period is greater than or equal to the preset speed, so that the alarm module 83 issues a prompt message.

[0016] It is clear from the above that if the drive component 4 regains magnetic attraction with the blade component 12 at the preset speed, the speed of the drive component 4 will further decrease due to the load. Conversely, if the drive component 4 does not regain magnetic attraction with the blade component 12 at the preset speed, the speed of the drive component 4 will inevitably be greater than or equal to the preset speed. Therefore, when the main control module 82 obtains a speed greater than the preset speed for the first time or continuously within a preset time, it indicates that the drive component 4 has not yet regained magnetic attraction with the blade component 12. At this time, the main control module 82 can activate the alarm module 83 to issue a prompt message, thereby reminding the user to manually adjust the magnetic attraction state between the milk frother 1 and the drive component 4, or to promptly inspect the drive component 4.

[0017] Furthermore, since users can monitor the status of the milk frother 1 in real time by checking whether the alarm module 83 issues a prompt message, in some embodiments, the alarm module 83 can be a light alarm module, an audible alarm module, or an audible and visual alarm module. When the alarm module 83 is a light alarm module, it can be an LED light source, a light-emitting diode, or other light alarm unit, enabling the milk frother to provide a light alarm prompt. When the prompt message is an audible alarm module, it can be a buzzer, a speaker, or other audible alarm unit, enabling the milk frother to provide an audible alarm prompt. Of course, in other embodiments, the alarm module 83 can also be a display screen installed on the milk frother, allowing the alarm module 83 to display text or code information.

[0018] Furthermore, to enable the detection module 81 to detect the rotational speed and input voltage of the drive component 4 separately, as shown in Figure 8, the detection module 81 includes a first detection submodule 811 and a second detection submodule 812, both of which are communicatively connected to the main control module 82. The first detection submodule 811 detects the input voltage of the drive component 4 and sends the measured input voltage to the main control module 82, while the second detection submodule 812 detects the rotational speed of the drive component 4 and sends the measured rotational speed to the main control module 82. It should be noted that, to enable the first detection submodule 811 to effectively detect the input voltage of the drive component 4, and the second detection submodule 812 to effectively detect the rotational speed of the drive component 4, in some embodiments, the first detection submodule 811 can be a voltage detection module, and the second detection submodule 812 can be a Hall effect sensor, through which the spindle rotational speed of the drive component 4 can be effectively detected. Of course, in other embodiments, the first detection submodule 811 and the second detection submodule 812 may also use other detection elements, but in this embodiment, the types of the first detection submodule 811 and the second detection submodule 812 are not specifically limited.

[0019] Example 2 Embodiment 3 of this utility model relates to a milk frother, such as... Figure 5 , Figure 6 and Figure 8 As shown, the milk frother includes: a base 3, a milk frother 1, a drive assembly 4, a positioning assembly 5, a magnetic suction assembly 6, and a control device 8 as described in Embodiment 1.

[0020] Among them, combined Figure 7 As shown, the base 3 is used to detachably mount the liquid storage container 2; secondly, combined with... Figure 1 and Figure 2 As shown, the milk frother 1 includes: a turbulence-disrupting component 11 and a paddle component 12 rotatably disposed within the turbulence-disrupting component 11.

[0021] Secondly, such as Figure 5 and Figure 6 As shown, the drive assembly 4 is mounted on the base 3, while the positioning assembly 5 is used to position the turbulence-disrupting component 11 at a target position within the liquid storage container 2. Additionally, the magnetic coupling assembly 6 is used to magnetically couple the paddle component 12 to the drive assembly 4 when the turbulence-disrupting component 11 is positioned at the target position within the liquid storage container 2.

[0022] In addition, the drive component 4 is used to receive the deceleration signal output by the detection module 81, and to reduce the speed to a preset speed lower than the current speed after receiving the deceleration signal.

[0023] From the above, it is clear that when the drive component 4 of the milk frother drives the milk frother 1 to foam the liquid in the storage container 2, the detection module 81 can detect the rotation speed and input voltage of the drive component 4 in real time. The main control module 82 can obtain the rotation speed and input voltage measured by the detection module 81. When the rotation speed of the main control module 82 at any input voltage is greater than any rotation speed in the target rotation speed range, it indicates that the magnetic attraction effect between the paddle component 12 of the milk frother and the drive component 4 is broken. At this time, the main control module 82 can send a signal to the drive component 4. The drive component outputs a deceleration signal, which enables the drive component 4 to reduce its rotation speed to a preset speed lower than the current speed after receiving the deceleration signal. This helps to re-establish a stable magnetic attraction between the paddle component 12 and the drive component 4, so that the user does not need to remove the milk frothing device or pour out the liquid milk. This not only avoids contamination of the liquid milk, but also effectively improves the stability of the milk frothing generator 1 when frothing liquid milk. It also prevents the milk frothing generator 1 from detaching from the target position in the liquid storage container 2 due to magnetic attraction failure when frothing liquid milk.

[0024] Specifically, in some embodiments, such as Figure 5 As shown, the magnetic attraction assembly 6 includes a first magnetic attraction module 61 and a second magnetic attraction module 62. The first magnetic attraction module 61 is disposed on the propeller component 12, while the second magnetic attraction module 62 is disposed on the drive assembly 4. The second magnetic attraction module 62 is used for magnetic coupling with the first magnetic attraction module 61. Furthermore, it is worth mentioning that in some embodiments, such as... Figure 2 As shown, the first magnetic module 61 includes at least one first magnetic component 611, and when there is one first magnetic component 611, the first magnetic component 611 is an annular structure formed around the axis of the blade component 12. When there are multiple first magnetic components 611, such as... Figure 2 As shown, each of the first magnetic components 611 is equidistantly arranged around the axis of the blade component 12, and the polarities of any two adjacent first magnetic components 611 are opposite. Similarly, the structure of the first magnetic module 61 is as follows: Figure 5 As shown, the second magnetic module 62 includes: a turntable 621 coaxially connected to the drive assembly 4, and at least one second magnetic component 622 disposed on the turntable 621. When there is one second magnetic component 622, the second magnetic component 622 is an annular structure formed around the axis of the turntable 621. When there are multiple second magnetic components 622, such as... Figure 5 As shown, each of the second magnetic components 622 is arranged equidistantly around the axis of the turntable 621, and the polarities of each pair of adjacent second magnetic components 622 are opposite.

[0025] For example, in some embodiments, such as Figure 2 As shown, there are four first magnetic components 611, which are equidistantly arranged in a ring around the axis of the blade component 12. The polarities of any two adjacent first magnetic components 611 are opposite, resulting in an angular difference of 45 degrees between any two adjacent first magnetic components 611. The four first magnetic components 611 are arranged as follows: Figure 5 and Figure 6 As shown, four second magnetic components 622 are also provided, and the four second magnetic components 622 can be equidistantly arranged around the axis of the turntable 621. The polarities of each pair of adjacent second magnetic components 622 are opposite. Therefore, when the positioning assembly 5 positions the turbulence-disrupting component 11 at the target position within the liquid storage container 2, each first magnetic component 611 on the paddle component 12 can automatically magnetically couple with each second magnetic component 621 on the drive assembly 4, such as... Figure 5 As shown, the drive assembly 4 can drive the paddle component 12 to rotate according to the corresponding command, thereby agitating the liquid milk and allowing it to circulate within the storage container 2, thus achieving foaming of the liquid milk. Furthermore, it should be noted that in some embodiments, only one of the first magnetic component 611 and the second magnetic component 621 may be provided. When both the first magnetic component 611 and the second magnetic component 621 are provided, their polarities are opposite, allowing them to achieve magnetic coupling. This positions the paddle component 12 relative to the drive assembly 4, enabling the drive assembly 4 to drive the paddle component 12 to rotate.

[0026] In addition, in order for the positioning component 5 to position the flow-dispersing component 11 at the target location within the liquid storage container 2, in some embodiments, the positioning component 5 may also use magnetic attraction to position the flow-dispersing component 11 at the target location within the liquid storage container 2. Specifically, in some embodiments, such as Figure 6As shown, the positioning component 5 includes a third magnetic module 51 and a fourth magnetic module 52. The third magnetic module 51 is disposed on the flow-dispersing component 11, while the fourth magnetic module 52 is disposed on the base 3. The fourth magnetic module 52 is used to magnetically fix itself to the third magnetic module 51, so that the flow-dispersing component 11 can be magnetically positioned at the target location within the liquid storage container 2. Furthermore, it is worth mentioning that in some embodiments, such as... Figure 2 As shown, the third magnetic module 51 includes at least one third magnetic component 511. When there is one third magnetic component 511, the third magnetic component 511 is a ring-shaped structure formed around the axis of the turbulence-inducing component 11. When there are multiple third magnetic components 511, such as... Figure 2 As shown, each of the third magnetic components 511 is equidistantly arranged around the axis of the turbulence-inducing component 11, and the polarities of any two adjacent third magnetic components 511 are opposite. Similarly, the structure of the corresponding third magnetic module 51 is as follows: Figure 3 As shown, the fourth magnetic module 52 includes at least one fourth magnetic component 521. When there is only one fourth magnetic component 521, it is an annular structure formed around the axis of the base 3. When there are multiple fourth magnetic components 521, such as... Figure 3 As shown, each of the fourth magnetic components 521 is equidistantly arranged around the axis of the base 3, and the polarities of each pair of adjacent third magnetic components 511 are opposite.

[0027] For example, in some embodiments, such as Figure 2 As shown, there are three third magnetic components 511, and the three third magnetic components 511 are arranged equidistantly around the axis of the turbulence-inducing component 12, such that the angular difference between any two adjacent third magnetic components 511 is 120 degrees. The structure of the corresponding third magnetic module 51 is as follows: Figure 3 and Figure 4 As shown, there are twelve fourth magnetic components 521, such that the angle difference between any two adjacent fourth magnetic components 521 is 30 degrees. Therefore, no matter what angle the turbulence component 11 of the milk frother 1 is placed in the liquid storage container 2, the turbulence component 11 can be magnetically attracted to one of the three third magnetic components 511 on the base 3 by means of the three first magnetic components 521, so that the turbulence component 11 can be automatically positioned in the target position in the liquid storage container 2, thereby completing the fixation of the turbulence component 11 in the liquid storage container 2.

[0028] Additionally, it is worth mentioning that in some embodiments, such as Figure 5 and Figure 6As shown, the drive component 4 is a motor, so when the second detection submodule 812 uses a Hall detection element, the rotational speed of the motor spindle can be directly detected. Of course, in other embodiments, the drive component 4 can also be other devices, but in this embodiment, the type and structure of the drive component 4 are not specifically limited.

[0029] Those skilled in the art will understand that the above embodiments are specific implementations of the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
