Description

TECHNICAL FIELD

[0001] Part of embodiments of the present application relates to a milk frother, in particular to a control method of a milk frother, a milk frothing method and a milk frother. BACKGROUND

[0002] The milk frother is a device that uses a generating device to generate vortex in a liquid milk in a storage container, and continuously stirs the liquid milk in the storage container by the generating device, and continuously filters, cuts and heats the liquid milk during the stirring, so as to generate milk froth.

[0003] At present, some milk frothers have a milk froth generating device fixed in the storage container of the milk frother by magnetic attraction, so that the driving assembly of the milk frother can drive the paddle part of the milk froth generating device to rotate, thereby realizing the production of milk froth. However, the inventor found that when the paddle part of the milk froth generating device rotates, the magnetic attraction force between the driving assembly and the paddle part is often affected by the inertia generated by the rotation of the paddle part, thereby destroying the magnetic attraction coupling between the driving assembly and the paddle part, resulting in the failure of the magnetic attraction between the two, so that the milk froth generating device cannot stably froth the liquid milk in the storage container, and in severe cases, the milk froth generating device can even be separated from the target position in the storage container. SUMMARY

[0004] The purpose of the embodiments of the present application is to design a control method of a milk frother, a milk frothing method and a milk frother, which can effectively improve the stability of the milk froth generating device when frothing the liquid milk, and avoid the milk froth generating device from being separated from the target position in the storage container due to the failure of magnetic attraction when frothing the liquid milk.

[0005] In order to achieve the above purpose, part of embodiments of the present application provides a control method of a milk frother, which is used for controlling a driving assembly of the milk frother, so that the driving assembly drives a milk froth generating device fixed in a storage container of the milk frother by magnetic attraction, and the milk froth generating device froths liquid milk in the storage container. The control method comprises the following steps: Real-time detection of the rotation speed and input voltage of the driving assembly; According to the measured rotation speed and input voltage, it is judged whether the working state of the milk froth generating device is abnormal; If it is determined that the working state of the milk froth generating device is abnormal, the rotation speed of the driving assembly is reduced to a preset rotation speed which is less than the current rotation speed.

[0006] In addition, part of embodiments of the present application also provides a milk frothing method of a milk frother, comprising the following steps: According to the current instruction, the driving assembly of the milk frother is controlled, so that the driving assembly drives the milk froth generating device magnetically fixed in the liquid storage container of the milk frother at a target rotating speed, and the milk froth generating device froths the liquid milk contained in the liquid storage container. The driving assembly is controlled by using the control method.

[0007] In addition, some embodiments of the present application also provide a milk frother, which comprises: a base for detachably arranging the liquid storage container; a milk froth generating device detachably arranged in the liquid storage container and magnetically fixed with the base; a driving assembly arranged on the base and magnetically coupled with the milk froth generating device, for driving the milk froth generating device to froth the liquid milk contained in the liquid storage container; a detection module for detecting the rotating speed of the driving assembly and the input voltage of the driving assembly; a main control module communicatively connected with the driving assembly and the detection module; the main control module is used for obtaining the rotating speed and the input voltage measured by the detection module, and judging whether the working state of the milk froth generating device is abnormal according to the obtained rotating speed and input voltage; the main control module is also used for reducing the rotating speed of the driving assembly to a preset rotating speed less than the current rotating speed when it is determined that the working state of the milk froth generating device is abnormal.

[0008] Compared with the prior art, when the driving assembly of the milk frother drives the milk froth generating device to froth the liquid contained in the liquid storage container, the rotating speed and the input voltage of the driving assembly are detected in real time, so that whether the working state of the milk froth generating device is abnormal can be accurately judged. For example, when the magnetic attraction effect between the milk froth generating device and the driving assembly is destroyed, the rotating speed of the driving assembly under the same input voltage will instantaneously increase at this time. Therefore, whether the working state of the milk froth generating device is abnormal can be accurately judged by detecting the rotating speed and the input voltage of the driving assembly. Once it is determined that the working state is abnormal, the rotating speed of the driving assembly can be reduced to a preset rotating speed less than the current rotating speed, so that the milk froth generating device and the driving assembly can reestablish stable magnetic attraction. Therefore, the user does not need to take out the milk froth generating device and does not need to pour out the liquid milk, so that not only the liquid milk can be prevented from being contaminated, but also the stability of the milk froth generating device when frothing the liquid milk can be effectively improved, and the phenomenon that the milk froth generating device deviates from the target position in the liquid storage container when frothing the liquid milk due to magnetic attraction failure can be avoided.

Figure 11 DETAILED DESCRIPTION

[0010] In order to make the objects, technical solutions, and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art can understand that, in the embodiments of the present application, many technical details are presented in order to make the reader better understand the present application. However, the technical solutions claimed by the present application can be implemented even without these technical details and based on various changes and modifications of the following embodiments.

[0011] Embodiment One Embodiment one of the present application relates to a control method of a milk frothing device, as shown in Figures 9 and 10, the control method is used to control a driving assembly 4 of the milk frothing device, so that the driving assembly 4 drives a milk frothing device 1 which is magnetically attracted and fixed in a liquid storage container 2 of the milk frothing device, so that the milk frothing device 1 froths liquid milk contained in the liquid storage container 2, and, as shown in Figures 11 and 12, the control method includes the following steps: Figure 5 and Figure 6 Figure 8 Step 810, real-time detection of the rotational speed and input voltage of the driving assembly 4. ​​​​

[0012] Step 820, according to the measured speed and input voltage, determine whether the working state of the milk bubble generating device 1 appears abnormal.

[0013] Step 830, if the working state of the milk bubble generating device 1 appears abnormal, the speed of the driving assembly 4 is reduced to a preset speed less than the current speed. If the working state of the milk bubble generating device 1 does not appear abnormal, return to step 810.

[0014] From the above, it is not difficult to see that when the driving assembly 4 of the milk bubble machine drives the milk bubble generating device 1 to foam the liquid in the liquid storage container 2, through real-time detection of the speed and input voltage of the driving assembly 4, the working state of the milk bubble generating device 1 can be accurately determined whether it is abnormal. For example, when the magnetic attraction effect between the milk bubble generating device 1 and the driving assembly 4 is destroyed, the speed of the driving assembly 4 under the same input voltage will instantaneously increase, so by detecting the speed and input voltage of the driving assembly 4, the working state of the milk bubble generating device 1 can be accurately determined whether it is abnormal. Once it is determined that the milk bubble generating device 1 is abnormal, the speed of the driving assembly 4 can be reduced to a preset speed less than the current speed, which can reestablish stable magnetic attraction between the milk bubble generating device 1 and the driving assembly 4, so that the user does not need to take out the milk bubble generating device and does not need to pour out the liquid milk, thereby not only avoiding pollution of the liquid milk, but also effectively improving the stability of the milk bubble generating device 1 when foaming the liquid milk, avoiding the phenomenon that the milk bubble generating device 1 separates from the target position in the liquid storage container 2 when foaming the liquid milk due to magnetic attraction failure.

[0015] And when the paddle component 13 of the milk bubble generating device 1 is normally magnetically coupled with the driving assembly 4, the driving assembly 4 can normally drive the paddle component 13 to rotate according to the current input voltage, so that the paddle component 13 can stir the liquid milk in the liquid storage container 2 when rotating, and the liquid milk can circulate in the liquid storage container 2. When the magnetic attraction effect between the paddle component 13 of the milk bubble generating device 1 and the driving assembly 4 is destroyed, the load connected with the driving assembly 4 becomes smaller and disappears, so that the speed of the driving assembly 4 itself will continuously rise under the same input voltage. Therefore, in order to accurately determine whether the working state of the milk bubble generating device 1 is abnormal according to the measured speed and input voltage, in another embodiment, the step of determining whether the working state of the milk bubble generating device 1 is abnormal according to the obtained speed and voltage, i.e. step 820, specifically includes: According to the current measured input voltage, the target speed interval of the driving assembly 4 driving the load under the input voltage is obtained.

[0016] Compare the current measured speed with the target speed interval.

[0017] If the measured rotational speed is greater than any speed within the target rotational speed range, the milk frothing device 1 is deemed to be malfunctioning. Conversely, if the measured rotational speed is equal to any speed within the target rotational speed range, the milk frothing device 1 is deemed to be functioning normally.

[0018] For example, during the operation of the milk frothing device 1, the device may be impacted by the pouring of liquid milk and / or powder, potentially disrupting the magnetic attraction between the paddle component 13 and the drive assembly 4. Once this magnetic attraction is disrupted, the rotational speed of the drive assembly 4 will gradually increase. Conversely, when the magnetic attraction between the paddle component 13 and the drive assembly 4 is stable, the drive assembly 4 will rotate at a much lower speed than when the magnetic attraction was disrupted due to the load. For example, when the magnetic attraction between the paddle component 13 and the drive assembly 4 is intact, the drive assembly 4 rotates at 3000-5000 r / min due to the load. However, when the magnetic attraction is broken, the drive assembly 4, disconnected from the load, experiences a sudden increase in speed, typically to 8000-9000 r / min. Therefore, a target speed range can be set within the milk frother, such as 2000-5000 r / min, generally not exceeding 8000 r / min. If the measured speed of the drive assembly 4 exceeds this target range, it indicates that the magnetic attraction between the drive assembly 4 and the paddle component 13 has been broken, and the milk frother 1 is considered to be malfunctioning. Conversely, if the measured speed of the drive assembly 4 is equal to any speed within the target range, the milk frother 1 is considered to be functioning normally.

[0019] However, besides determining whether the milk frothing device 1 is malfunctioning in the liquid storage container 2 by detecting the rotational speed of the drive component 4, as an alternative, in some embodiments, step 120 specifically includes the following steps in determining whether the operating state of the milk frothing device 1 is malfunctioning based on the obtained rotational speed and input voltage: Based on the currently measured rotational speed, the target voltage range when drive component 4 drives the load at that rotational speed is determined.

[0020] The measured input voltage is compared with the target voltage range.

[0021] If the measured input voltage is lower than any voltage within the target voltage range, the milk frothing device 1 is deemed to be malfunctioning. Conversely, if the measured voltage is equal to any voltage within the target voltage range, the milk frothing device 1 is deemed to be functioning normally.

[0022] It is easy to see that, under a constant speed range, the input voltage when the magnetic attraction between the paddle component 13 of the milk frothing device 1 and the drive component 4 is disrupted is significantly different from the input voltage when the magnetic attraction between the paddle component 13 and the drive component 4 is stable. Therefore, when the drive component 4 is under a constant input voltage, its speed under no-load conditions will be significantly higher than its speed when driving a load. Therefore, in some embodiments, a target voltage range corresponding to different speeds of the drive component 4 when driving a load can be set within the milk frother. For example, if the normal speed of the drive component 4 when driving a load is set to 2000 r / min-5000 r / min, the target voltage range corresponding to this speed range is 12V-24V. If the speed of the drive component 4 when driving a load is increased to 8000 r / min, the target voltage corresponding to this speed is 30V. Therefore, once the voltage of the drive component 4 is measured to be much less than 30V when the rotation speed is 8000r / min, for example, when the voltage is measured to be 15V, it indicates that the magnetic attraction effect between the paddle component 13 of the milk frothing device 1 and the drive component 4 is destroyed. At this time, it can be determined that the working state of the milk frothing device 1 is abnormal.

[0023] Additionally, as a preferred embodiment, in some other embodiments, after reducing the rotational speed of the drive component 4 to a preset speed lower than the current rotational speed, i.e. after step 130, such as... Figure 9 As shown, the control method further includes the following steps: Step 840: Control the rotation speed of drive component 4 to gradually increase to the target rotation speed, and return to step 810.

[0024] When the rotational speed of the drive assembly 4 decreases, the paddle component 13 of the milk frothing device 1 can regain its magnetic attraction with the drive assembly 4. In order to prevent the paddle component 13 of the milk frothing device 1 from being disrupted again by rotational inertia or by the impact of the pouring of liquid milk and / or powder under the drive of the drive assembly 4, in some embodiments, the rotational speed of the drive assembly 4 can be controlled to gradually increase to the target speed. This allows the paddle component 13 to gradually increase its rotational speed under the drive of the drive assembly 4, thus greatly reducing the acceleration inertia generated by the paddle component 13 when the rotational speed is increased, and greatly mitigating the impact of the pouring of liquid milk and / or powder. This effectively prevents the magnetic attraction between the paddle component 13 and the drive assembly 4 from being disrupted again, and improves the stability of the milk frothing device when frothing liquid milk.

[0025] Furthermore, it is clear from the above that when the magnetic attraction between the blade component 13 and the drive assembly 4 is disrupted, the magnetic attraction can be re-established by reducing the rotational speed of the drive assembly 4 to the target rotational speed. Therefore, to ensure that the magnetic attraction between the blade component 13 and the drive assembly 4 is restored when the rotational speed of the drive assembly 4 is gradually increased, in some embodiments, after reducing the rotational speed of the drive assembly 4 to a preset speed lower than the current speed (i.e., after step 830) and before gradually increasing the rotational speed of the drive assembly 4 to the target rotational speed (i.e., before step 840), such as... Figure 9 As shown, the control method further includes the following steps: Step 831: Within a preset time period, the rotational speed of the drive component 4 is detected in real time; Step 832: Based on the measured rotation speed, determine whether the working state of the milk frothing device 1 has returned to normal.

[0026] Step 833: If it is determined that the working state of the milk frothing device 1 has not returned to normal, a prompt message is generated and issued. If it is determined that the working state of the milk frothing device 1 has returned to normal, step 840 is executed, that is, the rotation speed of the drive component 4 is gradually increased to the target rotation speed.

[0027] Specifically, the step of determining whether the working state of the milk frothing device 1 has returned to normal based on the measured rotation speed and input voltage includes the following steps: If the rotation speed measured continuously within the preset time period is greater than or equal to the preset rotation speed, it is determined that the milk frothing device 1 has not returned to normal. If the rotation speed measured for the first time or continuously within the preset time period is less than the preset rotation speed, it is determined that the milk frothing device 1 has returned to normal.

[0028] When the speed of the drive component 4 decreases to a preset speed lower than the current speed, it can help the blade component 13 and the drive component 4 re-establish magnetic attraction. When the blade component 13 and the drive component 4 re-establish magnetic attraction, the speed of the drive component 4 will instantly decrease 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 13 and the drive component 4 is broken, the rotational speed of the blade component 13 will instantly increase to 8000 r / min to 9000 r / min. Therefore, when setting the preset rotational speed, the preset rotational speed should be less than 8000 r / min. For example, the preset rotational speed can be set to 1500 r / min. When the drive component 4 regains magnetic attraction with the blade component 13 at this preset rotational speed, the rotational speed of the drive component 4 will further decrease due to the presence of the load. Therefore, after the rotational speed of the drive component 4 decreases to the preset rotational speed and before its rotational speed is gradually increased to the target rotational speed, the rotational speed of the drive component 4 can be detected within a preset time period. By detecting the rotational speed of the drive component 4, it is possible to accurately determine whether the working state of the milk frothing device 1 has returned to normal.

[0029] For example, the rotational speed of the drive component 4 can be detected three times consecutively within a preset time period. If the rotational speed of the drive component 4 measured on the first time or in any subsequent measurement is less than the preset speed, it indicates that the drive component 4 has regained its magnetic attraction with the paddle component 13. At this point, it can be determined that the working state of the milk frothing device 1 has returned to normal, and step 840 can continue to be executed, that is, the rotational speed of the drive component 4 is gradually increased to the target speed so that the milk frothing device 1 can continue to froth the liquid milk. Conversely, if the rotational speed of the drive component 4 measured three times is greater than or equal to the preset speed, it indicates that the drive component 4 has not regained its magnetic attraction with the paddle component 13. At this point, it can be determined that the working state of the milk frothing device 1 has not returned to normal, so a prompt message can be generated and issued to remind the user so that the user can manually adjust the magnetic attraction between the milk frothing device 1 and the drive component 4, or promptly repair the drive component 4.

[0030] It is easy to see that users can monitor the working status of the milk frother 1 in real time by checking for any prompts from the milk frother. For example, if the milk frother 1 is in an abnormal working state, it means that the magnetic attraction between the paddle component 13 and the drive component 4 has failed. In some cases, the entire milk frother 1 may even completely detach from its target position in the liquid storage container 2. This would prevent the milk frother from re-establishing the magnetic attraction between the milk frother 1 and the drive component 13 by reducing the speed of the drive component 4. Therefore, users can use external tools and manual methods to adjust and reposition the milk frother 1 in the liquid storage container 2 based on the prompts from the milk frother.

[0031] Furthermore, it should be noted that in some embodiments, the prompt information can be a light alarm, an audible alarm, or a combination of both. Therefore, when the prompt information is a light alarm, an LED light source, a light-emitting diode, or other light alarm unit can be installed on the milk frother to provide a light alarm. When the prompt information is an audible alarm, a buzzer, a speaker, or other audible alarm unit can be installed on the milk frother to provide an audible alarm. Of course, in other embodiments, a display can also be installed on the milk frother to display the prompt information in the form of text or code.

[0032] Example 2 Embodiment 2 of the present invention relates to a method for making milk foam using a milk frother, such as... Figure 10 As shown, the method for making milk foam includes the following steps: Step 1010: According to the current instruction, control the drive component 4 of the milk frother to drive the milk frothing device 1, which is magnetically fixed in the liquid storage container 2 of the milk frother, at the target speed, so that the milk frothing device 1 foams the liquid milk in the liquid storage container 2.

[0033] Step 1020: Control the drive component 4 using the control method described in Embodiment 1.

[0034] From the above, it is clear that when the drive component 4 of the milk frother drives the milk frothing device 1 to foam the liquid in the storage container 2, real-time detection of the drive component 4's rotation speed and input voltage can accurately determine whether the working state of the milk frothing device 1 is abnormal. For example, when the magnetic attraction between the milk frothing device 1 and the drive component 4 is broken, the rotation speed of the drive component 4 will instantly increase under the same input voltage. Therefore, by detecting the rotation speed and input voltage of the drive component 4, the working state of the milk frothing device 1 can be accurately determined. If any abnormality is detected, the speed of the milk frothing device 1 can be reduced to a preset speed lower than the current speed. This will allow a stable magnetic attraction to be re-established between the milk frothing device 1 and the drive component 4. This eliminates the need for the user to remove the milk frothing device or pour out the liquid milk, thus avoiding contamination of the liquid milk and effectively improving the stability of the milk frothing device 1 when frothing the liquid milk. It also prevents the milk frothing device 1 from detaching from the target position in the liquid storage container 2 due to magnetic attraction failure when frothing the liquid milk.

[0035] Specifically, in some embodiments, the target speed can be a speed preset by the milk frother. For example, the target speed of the drive component 4 can be preset through the control panel on the milk frother. When the main control module 7 of the milk frother receives the instruction, it can call the preset target speed to control the drive component 4 according to the current instruction, so that the drive component 4 drives the paddle component 13 of the milk frothing device 1 to rotate at the target speed.

[0036] In addition to being able to be preset via the control panel of the milk frother, the target rotation speed is also related to the volume of liquid milk currently in the storage container 2. As an alternative, in some embodiments, the target rotation speed can also be calculated from the volume of liquid milk currently in the storage container 2. Specifically, a liquid level sensor (not shown in the figure) can be installed in the liquid storage container 2. When liquid milk is contained in the liquid storage container 2, the liquid level sensor can detect the volume of liquid milk contained in the liquid storage container 2. The larger the volume of liquid milk contained in the liquid storage container 2 measured by the liquid level sensor, the higher the target rotation speed calculated by the milk frother based on the volume. Thus, when the drive component 4 drives the paddle component 13 of the milk frothing device 1 to rotate, the axial thrust generated by the paddle component 13 on the liquid milk during rotation can make the liquid milk circulate in the liquid storage container 2, thereby achieving the purpose of frothing.

[0037] Example 3 Embodiment 3 of the present invention relates to a milk frother, such as... Figure 5, Figure 6 , Figure 7 and Figure 11 As shown, the milk frother includes: a base 3, a milk frothing device 1, a drive assembly 4, a detection module 6, and a main control module 7.

[0038] Among them, such as Figure 5 and Figure 6 As shown, the base 3 is used to detachably mount the liquid storage container 2, and the milk foam generator 1 is detachably placed inside the liquid storage container 2. The milk foam generator 1 is used to magnetically fix to the base 3.

[0039] In addition, such as Figure 1 As shown, the drive assembly 4 is mounted on the base 3 and magnetically coupled to the milk frothing device 1. The drive assembly 4 drives the milk frothing device 1, causing the milk frothing device 1 to froth the liquid milk contained in the storage container 2. Furthermore, during the process of driving the milk frothing device 1, the rotational speed and input voltage of the drive assembly 4 can be detected in real time by the detection module 6.

[0040] Finally, combining Figure 11 As shown, the main control module 7 is also connected to the drive component 4 and the detection module 6 respectively. The main control module 7 is used to obtain the rotation speed and input voltage measured by the detection module 6. The main control module 7 is also used to determine whether the working state of the milk frothing device 1 is abnormal based on the obtained rotation speed and input voltage. The main control module 7 is also used to reduce the rotation speed of the drive component 4 to a preset speed lower than the current rotation speed when it is determined that the working state of the milk frothing device 1 is abnormal.

[0041] From the above, it is clear that when the drive component 4 of the milk frother drives the milk frothing device 1 to foam the liquid in the storage container 2, the detection module 6 can detect the rotation speed and input voltage of the drive component 4 in real time. The main control module 6 can then determine whether there is any abnormality in the working state of the milk frothing device 1 based on the rotation speed and input voltage measured by the detection module 6. For example, if the magnetic attraction between the milk frothing device 1 and the drive component 4 is disrupted, the rotation speed of the drive component 4 will instantly increase under the same input voltage. Therefore, by detecting the rotation speed and input voltage of the drive component 4 through the detection module 6, the main control module 6 can... The main control module 6 can accurately determine whether the working status of the milk frothing device 1 is abnormal. Once the main control module 6 determines that the milk frothing device 1 is abnormal, it can reduce the speed of the drive component 4 to a preset speed lower than the current speed. This allows the milk frothing device 1 to re-establish a stable magnetic attraction with 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 device 1 when frothing the liquid milk. It also prevents the milk frothing device 1 from detaching from the target position in the liquid storage container 2 due to magnetic attraction failure when frothing the liquid milk.

[0042] Specifically, in some embodiments, combined with Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the milk frothing device 1 includes: a turbulence-disrupting component 12, a paddle component 13, a filter screen 14, a first magnetic module 11, and a second magnetic module 15. Among them, as... Figure 5 and Figure 6 As shown, the turbulence-disrupting component 12 includes a cavity 121, at least one liquid inlet 128 communicating with the cavity 121, and at least one liquid outlet 123 communicating with the cavity 121. Next, as... Figure 5 and Figure 6 As shown, the blade component 13 is disposed in the cavity 121, and the blade component 13 is rotatable relative to the turbulence component 12 about a preset axis. The blade component 13 is used to agitate the liquid milk contained in the liquid storage container 2 when rotating, so that the liquid milk circulates in the liquid storage container 2 and continuously circulates between each liquid inlet 128 and each liquid outlet 123 through the cavity 121.

[0043] In addition, such as Figure 6 As shown, the filter screen 14 is disposed in the cavity 121 of the turbulence component 12. The filter screen 14 is used to filter and cut the liquid milk when it circulates between each liquid inlet 128 and each liquid outlet 123, so that the liquid milk produces milk foam.

[0044] Furthermore, it is worth noting that, such asFigure 2 As shown, the first magnetic module 11 is disposed on the turbulence-disrupting component 12 of the milk frothing device 1, and when the milk frothing device 1 is placed in the liquid storage container 2 of the milk frother, as... Figure 3 and Figure 6 As shown, the first magnetic module 11 can be magnetically fixed to the base 3 of the milk frother and is used to magnetically position the turbulence-disrupting component 12 at a target location within the liquid storage container 2. Secondly, as... Figure 2 As shown, the second magnetic module 15 is disposed on the paddle component 13 of the milk frothing device 1, and when the turbulence component 12 is positioned at the target position inside the liquid storage container 2, it combines with... Figure 5 and Figure 6 As shown, the second magnetic module 15 can be directly magnetically coupled to the drive component 4 of the milk frother, so that the drive component 4 can drive the paddle component 13 to rotate.

[0045] As can be seen from the above, the first magnetic module 11 can magnetically fix the milk frothing device 1 to the base 3 of the milk frother when it is placed in the liquid storage container 2 of the milk frother. This allows the turbulence-disrupting component 12 of the milk frothing device 1 to be automatically positioned at the target position in the liquid storage container 2. The second magnetic module 15 can also magnetically couple with the drive component 4 of the milk frother, allowing the drive component 4 to drive the paddle component 13 to rotate. Therefore, the installation of the milk frothing device 1 can eliminate the need for alignment with the base 3, thus enabling blind operation of the installation of the milk frothing device 1. This allows for quick installation of the milk frothing device 1 in the liquid storage container 2 without affecting the milk frothing of liquid milk.

[0046] In addition, in order to enable the base 3 to be magnetically fixed to the first magnetic module 11, in some other embodiments, such as Figure 3 and Figure 4 As shown, the base 3 includes: a base body 32 and a third magnetic module 31 disposed on the base body 32. The third magnetic module 31 is used to magnetically fix the base 32 to the first magnetic module 11, thereby positioning the turbulence-inducing component 12 at a target position within the liquid storage container 2. Similarly, in order to enable the drive component 4 to achieve magnetic coupling with the second magnetic module 15, in some other embodiments, such as... Figure 5 and Figure 6 As shown, the drive assembly 4 includes: a drive element 41 and a fourth magnetic module 42 coaxially connected to the drive end of the drive element 41. The fourth magnetic module 42 is also used for magnetic coupling with the second magnetic module 15, so that the drive element 41 drives the blade component 13 to rotate relative to the turbulence component 12 under the control of the main control module 7.

[0047] Specifically, in some embodiments, such as Figure 2As shown, the first magnetic module 11 includes at least one first magnetic component 111. When one first magnetic component 111 is provided, it is a ring-shaped structure formed around the axis of the flow-deflecting component 12. When multiple first magnetic components 111 are provided, such as... Figure 2 As shown, each of the first magnetic components 111 is equidistantly arranged in a ring around the axis of the turbulence-inducing component 12, and the polarities of any two adjacent first magnetic components 111 are opposite. For example, as... Figure 2 As shown, in some embodiments, three first magnetic components 111 are provided, and the three first magnetic components 111 are arranged equidistantly around the circumference of the turbulence-disrupting component 12, such that the angular difference between any two adjacent first magnetic components 111 is 120 degrees. Corresponding to the structure of the first magnetic module 11, the third magnetic module 31 includes at least one third magnetic component 311. When there is only one third magnetic component 311, it is a ring-shaped structure formed around the axis of the driving component 4. When there are multiple third magnetic components 311, they are combined... Figure 3 As shown, each of the third magnetic components 311 is equidistantly arranged around the axis of the drive assembly 4, and the polarities of any two adjacent third magnetic components 311 are opposite. It is easy to see from the above that, in some embodiments, such as... Figure 2 As shown, the first magnetic module 11 may include three first magnetic components 111, and corresponding to the three first magnetic components 111, such as... Figure 3 and Figure 4 As shown, there are twelve third magnetic components 311, such that the angle difference between any two adjacent third magnetic components 311 is 30 degrees. Therefore, no matter what angle the turbulence component 12 of the milk foam generator 1 is placed in the liquid storage container 2, the turbulence component 12 can be magnetically attracted to three of the third magnetic components 311 on the base body 31 by means of the three first magnetic components 111, so that the turbulence component 12 can be automatically positioned in the target position in the liquid storage container 2, thereby completing the installation of the turbulence component 12 in the liquid storage container 2.

[0048] Furthermore, in order to enable the second magnetic module 15 to achieve magnetic coupling with the driving component 4, in other embodiments, such as Figure 2 As shown, the second magnetic module 15 includes: a plurality of second magnetic components 151 disposed at the bottom of the blade component 13. For example, four second magnetic components 151 may be provided, and each second magnetic component 151 is equidistantly arranged around the axis of the blade component 13. Corresponding to the four second magnetic components 151, such as... Figure 5 and Figure 6As shown, the driving element 41 includes a motor 411 and a turntable 412 coaxially connected to the main shaft of the motor 411. The fourth magnetic module 42 includes a plurality of fourth magnetic components 421 distributed on the turntable 412. For example, the number of fourth magnetic components 421 is the same as that of the second magnetic components 151, such as four in each case. Each fourth magnetic component 421 can be equidistantly arranged around the axis of the turntable 422, and the polarity of each pair of adjacent fourth magnetic components 421 is opposite. Thus, when the turbulence-disrupting component 12 is automatically positioned at the target position within the liquid storage container 2, such as... Figure 5 and Figure 6 As shown, the blade component 13 can rotate slightly around its own axis by relying on the polarity relationship between each of the second magnetic components 151 and the four fourth magnetic components 421 on the base 3, thereby enabling the blade component 13 to automatically complete magnetic coupling with the drive component 4.

[0049] As can be seen from the above, when the milk frothing device 1 is placed in the liquid storage container 2, the first magnetic module 11 of the milk frothing device 1 and the third magnetic module 31 on the base 3 magnetically attract each other, allowing the milk frothing device 1 to be automatically positioned in the target position within the liquid storage container 2. At the same time, when the milk frothing device 1 is positioned in the target position, the second magnetic module 15 on the paddle component 13 magnetically couples with the fourth magnetic module 42 on the drive element 41, allowing the drive component 4 to drive the paddle component 13 to rotate. Therefore, the installation of the milk frothing device 1 can eliminate the need for alignment with the base 3, thus enabling blind operation of the installation of the milk frothing device 1. While not affecting the milk frothing device 1's ability to froth liquid milk, it also allows for the rapid installation of the milk frothing device 1 in the liquid storage container 2.

[0050] In addition, in order for the detection module 6 to detect the rotational speed and input voltage of the drive component 4 separately, such as Figure 11 As shown, the detection module 6 includes: a Hall effect detection submodule 61 for detecting the rotational speed of the drive component 4, and a voltage acquisition submodule 62 for detecting the input voltage of the drive component 4. Of course, in other embodiments, the detection module 6 may employ other detection elements, but in this embodiment, the type of the detection module 6 is not specifically limited.

[0051] It is clear from the above that this embodiment is an embodiment of a milk frother corresponding to Embodiment 1, and this embodiment can be implemented in conjunction with Embodiment 1. The relevant technical details mentioned in Embodiment 1 are still valid in this embodiment, and will not be repeated here to avoid repetition. Correspondingly, the relevant technical details mentioned in this embodiment can also be applied to Embodiment 1.

[0052] 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 in form and detail without departing from the spirit and scope of the present invention.
