Description

Technical Field

[0001] This application relates to the field of beverage equipment technology, and more particularly to a milk frother. Background Technology

[0002] A milk frother, also known as a milk foaming machine, is a device used to create milk foam. It works by injecting air into milk and vibrating it at high speed, causing the air bubbles to become trapped within the network structure of milk protein molecules, thus forming rich milk foam. Milk frothers are commonly used in coffee shops, restaurants, and kitchens. Milk foam can be consumed directly as a beverage or used as an ingredient in coffee and other dairy products.

[0003] Current milk frothers adjust the concentration of milk foam in beverages by manually regulating the airflow of the air intake component. However, current frothers cannot accurately control the concentration of the produced milk foam. Therefore, they cannot precisely control the concentration of milk foam according to the user's needs, failing to meet the diverse and personalized requirements of users regarding milk foam concentration.

[0025] This application describes several embodiments, but these descriptions are exemplary and not restrictive, and it will be apparent to those skilled in the art that many more embodiments and implementations are possible within the scope of the embodiments described herein. The embodiments, features, and elements disclosed in this application can also be combined with any conventional features or elements to form unique inventive solutions.

[0026] Please refer to the instruction manual appendix. Figures 1 to 10 The diagram shows a structural schematic of a milk frother according to an exemplary embodiment of this application. Figures 1 to 6 As shown, a milk frother according to an embodiment of this application includes an air intake assembly 1, a feeding assembly 2, a milk foam generating assembly 3, and a control module (not shown in the figure). The air intake assembly 1 includes an air delivery pipe 11 and a regulating valve 12 disposed on the air delivery pipe 11, the regulating valve 12 being configured to change the air delivery flow rate of the air delivery pipe 11. The feeding assembly 2 includes a material storage component 21 and a feeding pipe 22 connected to the material storage component 21, the material storage component 21 being configured to store materials. Both the feeding pipe 22 and the air delivery pipe 11 are connected to the milk foam generating assembly 3, the milk foam generating assembly 3 being configured to mix the materials conveyed by the feeding pipe 22 and the gas conveyed by the air delivery pipe 11 to generate a beverage. The control module includes a control circuit (not shown in the figure), the control module being configured to compare the set density of the beverage with the actual density of the generated beverage, and drive the air intake assembly 1 to adjust the air delivery flow rate based on the comparison result.

[0027] Specifically, Figures 1 to 3 The external structure of a milk frother according to an embodiment of this application is shown. Figures 4 to 6 A schematic diagram of the hidden body 5 of a milk frother according to an embodiment of this application is shown. Figures 7 to 8A schematic diagram of the hidden body 5 of a milk frother according to another embodiment of this application is shown, wherein the storage component 21 is externally provided with an insulated container 84 and a cooling pipe 85. The air intake component 1, the feeding component 2, the milk foam generating component 3, and the control module are all located inside the body 5. The working principle of the milk foam generator of this application is as follows: the air intake component 1 sends air into the milk foam generating component 3 through the air supply pipe 11; the feeding component 2 sends the material (the material is milk or a mixture including milk) into the milk foam generating component 3 through the feeding pipe 22; the milk foam generating component 3 includes a whipping shaft assembly (not shown in the figure), a drive component (not shown in the figure), and a pump assembly (not shown in the figure). The pump assembly is used to pump the air in the air supply pipe 11 and the material in the feeding pipe 22 into the whipping shaft assembly. The drive component is used to provide driving force for the pump and the whipping shaft assembly. The whipping shaft assembly is used to mix the air and the material and form rich and delicate milk foam through high-speed oscillation; the milk foam generated by the milk foam generating component 3 flows out through the liquid outlet 52 on the outer wall of the machine body 5, thereby forming the final beverage, namely milk foam or milk foam. Optionally, in the milk frother of this application, the control module is electrically connected to the air intake component 1, the feeding component 2, and the milk foam generating component 3. The control module can control the operation of the air intake component 1, the feeding component 2, and the milk foam generating component 3, enabling the milk frother to automatically generate milk foam beverages. The set density of the beverage refers to the ideal milk foam density desired by the user, while the actual density of the generated beverage refers to the density of the milk foam actually generated by the milk frother. The density of the milk foam is calculated by dividing the mass of the milk foam output from the milk foam generating component 3 by the volume of that milk foam. The milk foam concentration data is directly proportional to the milk foam density data. In actual use, the milk frother of this embodiment requires first generating a cup of milk foam beverage. The user obtains the actual density of the cup of milk foam beverage through measurement and calculation methods. Then, the user inputs the desired ideal milk foam set density into the milk frother. The control module obtains the actual density of the cup of milk foam beverage and the user's desired ideal milk foam set density, compares them, and drives the air intake component 1 to adjust the air flow rate to generate milk foam beverages with a density that meets the user's needs.

[0028] The milk frother of this embodiment includes a regulating valve 12 on the air delivery pipe 11. The regulating valve 12 can change the air flow rate of the air delivery pipe 11. The regulating valve 12 can be selected as a valve with micro-adjustment function to improve the adjustment accuracy. The milk frother also includes a control module, which is configured to compare the set density of the beverage with the actual density of the generated beverage, and drive the air intake component 1 to adjust the air flow rate based on the comparison result. Thus, the milk frother of this application can accurately adjust the density of the generated milk foam beverage according to the set density of the beverage and the actual density of the generated beverage, in order to meet the diverse and personalized needs of users for the concentration of milk foam generated by the milk frother.

[0029] For example, the control module can drive the air intake component 1 to adjust the air flow rate as follows: if the actual density of the generated beverage is less than the set density of the beverage, the air flow rate of the air intake component 1 of the milk frother decreases; if the actual density of the generated beverage is greater than the set density of the beverage, the air flow rate of the air intake component 1 of the milk frother increases.

[0030] In one exemplary embodiment, such as Figure 1 As shown, the milk frother also includes an input module 4, which is electrically connected to the control circuit.

[0031] Input module 4 is configured to allow manual input of the desired density of the beverage and the actual density of the generated beverage; or,

[0032] Input module 4 is configured to allow manual input of the beverage's set density, as well as the actual volume and weight of the generated beverage. Control module is configured to derive the actual density of the generated beverage based on its actual volume and weight.

[0033] Specifically, the milk frother of this application can be set to a semi-automatic or manual working mode to control the concentration of the generated milk foam, including but not limited to the following embodiments:

[0034] In some embodiments, the milk frother of this application is manually controlled to generate milk foam concentration. After the user obtains the actual density of the generated beverage through measurement and calculation, the operator needs to manually input the set density of the next beverage and the actual density of the generated beverage into the input module 4.

[0035] In some embodiments, the milk frother of this application is manually controlled to generate milk foam concentration. After obtaining the actual volume and weight of the generated beverage through measurement and calculation, the operator needs to manually input the set density of the next beverage into the input module 4. The operator manually inputs the actual volume and weight of the generated beverage, and the control module needs to calculate the actual density of the generated beverage based on the actual volume and weight of the generated beverage.

[0036] In some embodiments, the milk frother of this application is a semi-automatic milk frother that controls the concentration of milk froth. The actual weight data of the generated beverage can be automatically acquired by the input module 4 (for example, the device for measuring the weight of the generated beverage can be connected to the input module 4). The preset volume of the generated beverage is selected by the input module 4, and the generated beverage is contained in a cup 71 of the preset volume. In this way, the input module 4 knows the actual volume of the generated beverage in advance. Therefore, the milk frother of this embodiment does not require the user to manually input the actual volume and weight of the generated beverage into the input module 4, making it a semi-automatic milk frother that controls the concentration of milk froth.

[0037] The beverage is prepared using a cup 71 of a preset volume. The cup 71 can be of various types, such as... Figure 1 The device can include large and small cups, both with preset graduation lines. The user first selects the type of cup 71 via input module 4. Then, the user visually observes that the milk foam output from the milk foam generating component 3 reaches the preset graduation line on the cup 71, at which point the milk frother stops working. When using a cup 71 with a preset volume, the user can input the set mass of the beverage and the actual mass of the generated beverage into input module 4. The control module compares the set mass and the actual mass of the generated beverage, and drives the air intake component 1 to adjust the airflow rate based on the comparison result.

[0038] It is understood that the type of cup 71 with the preset volume used in this application is not limited to large cups and small cups.

[0039] In one exemplary embodiment, such as Figure 1 As shown, the input module 4 includes a display screen 41 and / or a button 42. The milk frother includes a body 5. The display screen 41 and the button 42 are both located on the outer wall of the body 5. The display screen 41 and the button 42 are both configured to input the working parameters of the milk frother.

[0040] Specifically, the operating parameters of the milk frother include the set density of the beverage, the actual density of the generated beverage, the actual volume and weight of the generated beverage, the model of the cup 71 used to hold the milk foam, and the rotation speed of the milk foam generating component 3.

[0041] In some exemplary embodiments, such as Figures 1 to 3 As shown, the milk frother also includes a weighing component 6 and a volume measuring component 7. The weighing component 6 is configured to measure the actual weight of the generated beverage, and the weighing component 6 includes a measuring scale 61.

[0042] The volume measuring device 7 is configured to accommodate the generated beverage and measure the actual volume of the generated beverage. The volume measuring device 7 includes a cup 71 with a preset volume.

[0043] Specifically, the user first weighs the empty volume measuring component 7 using the weighing device 6, then starts the milk frother. The milk frother produces a beverage that is placed in the volume measuring component 7. The side wall of the volume measuring component 7 has graduation lines. The user visually observes that the milk foam output from the milk foam generating component 3 to the volume measuring component 7 reaches the graduation line indicating the user's desired volume, at which point the milk frother stops producing milk foam. The user then moves the volume measuring component 7 containing milk foam to the weighing device 6 and measures the total weight of the milk foam and the volume measuring component 7. The actual weight of the produced beverage is equal to the total weight of the milk foam and the volume measuring component 7, minus the weight of the empty volume measuring component 7. The user obtains the actual weight and actual volume of the produced beverage using both the weighing device 6 and the volume measuring component 7. The user can manually calculate the actual weight of the produced beverage by dividing it by the actual volume of the produced beverage to obtain the actual density of the produced beverage; alternatively, the user can input the actual weight and actual volume of the produced beverage into the input module 4, and the milk frother's control module will calculate the actual density of the produced beverage. Both methods are within the scope of protection of this application.

[0044] The weighing component 6 can be either a weighing scale 61 or a weighing sensor, both of which are within the scope of protection of this application.

[0045] In some exemplary embodiments, the weighing element 6 is electrically connected to the input module 4, and the weighing element 6 is configured to send the actual weight data of the generated beverage to the input module 4.

[0046] Specifically, the weighing component 6 is configured to send the actual weight data of the generated beverage to the input module 4, which improves the automation level of the milk frother and eliminates the need for the user to manually input the actual weight data of the generated beverage.

[0047] In some exemplary embodiments, such as Figure 6 , Figure 9 and Figure 10 As shown, the intake assembly 1 also includes a linkage 13 and a drive 14. The drive 14 is electrically connected to the control circuit. The regulating valve 12 includes a valve stem (not shown in the figure). The linkage 13 is connected to the valve stem, and the drive 14 is connected to the linkage 13.

[0048] The drive element 14 is configured to drive the linkage element 13 to move, thereby driving the valve stem to move, so as to adjust the air flow rate of the air supply pipe 11.

[0049] Specifically, compared to the method of manually turning the valve of the gas delivery pipe 11 by the user, the method of using a control circuit electrically connected to the drive component 14, and the drive component 14 driving the regulating valve 12 through the linkage component 13 to adjust the gas delivery flow of the gas delivery pipe 11, can improve the mechanization level of the milk frother and enable the milk frother to accurately produce milk foam beverages of different concentrations.

[0050] The drive unit 14 can be driven by electricity or pneumatic means, both of which are within the protection scope of this application.

[0051] In some exemplary embodiments, such as Figure 9 and Figure 10 As shown, the driving component 14 is a stepper motor 141, the linkage 13 is a reduction gear set 131, and the regulating valve 12 is a needle valve 121.

[0052] Specifically, the valve core of the needle valve 121 is a sharp cone. The needle valve 121 has the advantages of precise adjustment and shut-off. The needle valve 121 can be a micro-adjustment valve with graduations and threaded interfaces. Selecting the needle valve 121 and the stepper motor 141 can improve the accuracy of the air intake assembly 1 in adjusting the airflow.

[0053] In some exemplary embodiments, such as Figure 5 and Figure 9 As shown, the air supply pipe 11 includes an air inlet pipe 111 and an air outlet pipe 112. The air outlet 1111 of the air inlet pipe 111 is connected to the inlet end 1211 of the needle valve 121, the air inlet 1121 of the air outlet pipe 112 is connected to the outlet end 1212 of the needle valve 121, and the air outlet 1122 of the air outlet pipe 112 is connected to the milk foam generating component 3.

[0054] In some exemplary embodiments, such as Figures 1 to 3 As shown, the milk frother also includes a body 5, and the air intake component 1, the feeding component 2 and the milk foam generating component 3 are all located inside the body 5.

[0055] Specifically, the body 5 serves to house the various functional components of the milk frother, and the body 5 can also form a well-sealed cavity, which is beneficial for the storage component 21 to preserve the material.

[0056] In some exemplary embodiments, such as Figures 1 to 3 As shown, the outer wall of the machine body 5 is equipped with a support 51, and the milk frother is equipped with a volume measuring component 7 for accommodating the generated beverage. The volume measuring component 7 is supported by the support 51.

[0057] In some exemplary embodiments, such as Figures 5 to 8 As shown, the milk frother also includes a temperature control component 8, which is located inside the body 5. The temperature control component 8 includes a refrigeration component and a heat preservation component. The temperature control component 8 can control the temperature of the material in the storage container 21 to the set temperature.

[0058] Optionally, setting the temperature to between 0 and 8 degrees can extend the shelf life of the materials in the storage container 21 and prevent the materials from deteriorating.

[0059] In some exemplary embodiments, such as Figures 5 to 8As shown, the refrigeration assembly includes a compressor 81, a heat exchanger 82, and a thermostat 83, all housed within the casing 5.

[0060] The insulation assembly includes an insulation container 84 and a cooling pipe 85 surrounding the outer wall of the insulation container, with at least a portion of the storage component 21 located within the inner cavity of the insulation container 84.

[0061] A fan 85 is also provided at the lower part of the drive component of the milk foam generating component 3.

[0062] In some exemplary embodiments, such as Figure 4 and Figure 8 As shown, the milk frother is a double-headed milk frother. The double-headed milk frother includes a body 5, which contains two sets of air intake components 1, two sets of feeding components 2, and two sets of milk foam generating components 3. The outer wall of the body 5 is provided with two liquid outlets 52.

[0063] Specifically, the milk frother is a dual-head milk frother, so that the two storage containers 21 can hold different materials, and the types of beverages flowing out from the two dispensing nozzles 52 are different. For example, one storage container 21 holds milk, and the other storage container 21 holds a mixture of milk and other materials.

[0064] This application provides a method for controlling the concentration of milk foam generated by a milk frother. The milk frother is the milk frother described in any of the exemplary embodiments above. The method for controlling the concentration of milk foam generated by the milk frother includes:

[0065] Obtain the actual density of the beverage produced by the milk frother;

[0066] The control module of the milk frother compares the set density of the beverage with the actual density of the generated beverage, and adjusts the air flow rate of the air intake component of the milk frother based on the comparison result.

[0067] Specifically, the method for controlling the concentration of milk foam generated by the milk frother provided in this application includes the milk frother described in any of the above exemplary embodiments, and therefore has the structural features and advantages of the milk frother described in the above exemplary embodiments, which will not be repeated here.

[0070] The actual volume and weight of the beverage are input through the input module, and the control module calculates the actual density of the beverage based on the actual volume and weight.

[0071] In some exemplary embodiments, the control module of the milk frother compares the set density of the beverage with the actual density of the generated beverage, and adjusts the air flow rate of the air intake component of the milk frother based on the comparison result, including:

[0072] When the actual density of the generated beverage is less than the set density of the beverage, the air flow rate of the air intake component of the milk frother decreases.

[0073] When the actual density of the generated beverage is greater than the set density of the beverage, the air flow rate of the air intake component of the milk frother increases.

[0074] In an exemplary embodiment, the method for controlling the concentration of milk foam generated by the milk frother includes, in sequence:

[0075] The milk frother produces milk foam beverages, and the produced milk foam beverages are collected using a volume measuring device.

[0076] When the user visually determines that the liquid level of the generated beverage has reached the preset volume corresponding to the liquid level of the volume measuring device, the milk frother stops working.

[0077] The volume measuring device is transferred to the weighing device, which measures the actual weight of the generated beverage to obtain the actual density of the generated beverage.
