Description

Technical Field

[0001] This invention relates to the field of food processor technology, and more specifically, to a control method, device, storage medium, and food processor for a food processor. Background Technology

[0002] Liquids containing protein, such as milk and soy milk, can generate a large number of bubbles through foaming processes, thereby optimizing the taste and improving the quality of the beverage. The fineness and stability of the bubbles are key indicators that determine the quality of the beverage.

[0003] In related technologies, foaming machines produce larger bubbles in beverages.

[0004] However, larger bubble sizes can affect the amount of bubbles that accumulate on top of the beverage, and larger bubbles are more likely to burst and have a shorter lifespan, resulting in technical problems such as poor bubble fineness and instability in the product. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0006] Therefore, the first aspect of the present invention provides a method for controlling a food processor.

[0007] A second aspect of the present invention provides a control device for a food processor.

[0008] A third aspect of the present invention provides a control device for a food processor.

[0009] A fourth aspect of the present invention provides a readable storage medium.

[0010] The fifth aspect of the present invention provides a food processor.

[0011] In view of this, a first aspect of the present invention provides a control method for a food processor, the food processor including a conveying device, an accelerating device, and an air intake device, the control method including: controlling the conveying device to extract a first liquid and convey the first liquid to the accelerating device based on a beverage preparation instruction; and controlling the air intake device to deliver gas into the accelerating device.

[0012] In this technical solution, the food processor includes a conveying device, an accelerating device, and an air intake device. One end of the accelerating device is connected to the conveying device, and the other end of the accelerating device is connected to the cooking chamber. The air intake device is connected to the accelerating device.

[0013] During operation, the conveying device is used to deliver liquid into the acceleration device, which can increase the flow rate of the delivered liquid. The air intake device can introduce air into the liquid after it has been successfully accelerated by the acceleration device.

[0014] Based on this, the control method for the food processor is as follows:

[0015] When the food processor is determined to need foaming based on the received beverage preparation instructions, the control conveyor draws in a first liquid and delivers it to the acceleration device. This first liquid, used for foaming, can be a protein-rich solution such as milk or soy milk. After being delivered to the acceleration device, the device accelerates the first liquid, allowing it to flow at high speed within the device. Following the delivery of the first liquid to the acceleration device, the control air intake device then delivers gas into the acceleration device.

[0016] The first liquid, after being accelerated and flowing at high speed, can shear the gas delivered by the air intake device. Under the shearing and mixing action between the high-speed liquid and gas, microbubbles with a diameter of less than 100μm can be generated. Finally, the microbubbles are introduced into the cooking chamber through the acceleration device and form a dense and long-lasting microbubble layer on the liquid surface in the cooking chamber.

[0017] By limiting the above control methods, on the one hand, the amount of bubbles accumulating above the liquid can be increased by reducing the size of the bubbles, thereby improving the smoothness of the bubble layer on top of the food and providing users with a creamy texture. On the other hand, the duration of bubble existence can be extended by reducing the size of the bubbles, allowing the bubble layer on top of the food to persist for a longer period.

[0018] For example, in making milk coffee, if the diameter of the bubbles in the bubble layer is around 2mm in a 20cm deep beverage, the duration of the bubbles is about 0.1 seconds. When the microbubbles with a diameter of around 20μm are produced by the above control method in this application, the duration of the microbubbles is about 1000 seconds.

[0019] Therefore, this application solves the technical problems of poor bubble fineness and poor stability in related technologies by controlling the food processor to produce microbubbles with a diameter of less than 100μm, thereby achieving the technical effect of improving the foaming quality of the food processor and improving the quality of the beverages produced.

[0020] In addition, the control method for the food processor provided by the present invention may also have the following additional technical features:

[0021] In some technical solutions of the present invention, optionally, the step of controlling the air intake device to deliver gas into the acceleration device includes: determining the foaming density and foaming amount according to the beverage preparation instructions, and determining the target flow rate and target duration according to the foaming density and foaming amount; when the working time of the conveying device reaches the preset duration, controlling the air intake device to deliver gas with a flow rate of the target flow rate into the acceleration device; when the working time of the air intake device reaches the target duration, controlling the conveying device and the air intake device to stop working.

[0022] In this technical solution, the step of controlling the intake device to deliver gas into the acceleration device specifically includes:

[0023] After receiving the beverage preparation instruction, the corresponding target duration is determined based on the foaming density and foaming amount contained in the beverage preparation instruction. The higher the foaming density, the denser the foam layer and the longer the residence time. Conversely, the lower the foaming density, the sparser the foam layer and the shorter the residence time. The foaming amount affects the thickness of the foam layer. The higher the foaming amount, the thicker the foam layer.

[0024] If the delivery time of the first liquid from the conveying device to the acceleration device reaches the preset time, it indicates that the first liquid has reached the foaming position. Then, the air intake device is controlled to deliver gas into the acceleration device, and the flow rate of the gas delivered into the acceleration device is controlled by controlling the power of the air intake device to achieve the target flow rate. By controlling the flow rate of the gas impacted by the first liquid, the density of the formed bubbles can be changed to ensure that the produced microbubble layer can meet the cooking requirements.

[0025] The preset time corresponds to the time required for the first liquid to flow to the foaming area. By controlling the conveying component to work for the preset time, it can be ensured that the gas delivered by the air intake device to the acceleration device can be impacted by the high-speed flowing first liquid, thus avoiding the acceleration device from outputting airflow at the beginning of operation and achieving the technical effect of improving the reliability of the food processor.

[0026] During the operation of the air intake device, microbubbles are continuously produced at the outlet of the acceleration device. When the air intake device reaches the target operating time, it indicates that the total amount of microbubbles produced has met the requirements. At this point, the conveying device and the air intake device are stopped to complete the foaming operation. By controlling the operating time of the air intake device and the conveying device according to the target time, the thickness of the microbubble layer can be made to meet the requirements of the corresponding beverage, avoiding the impact on the quality of the beverage due to insufficient microbubble layer thickness.

[0027] In summary, by limiting the above control methods, the food processor can accurately control the foaming process, thereby improving the control precision of the food processor, enhancing the quality of the cooked food, and increasing the intelligence level of the food processor.

[0028] Optionally, in some technical solutions of the present invention, the food processor further includes a heating device. Before the step of controlling the conveying device to extract the first liquid and convey the first liquid to the acceleration device, the control method further includes: determining a target temperature according to a beverage preparation instruction; controlling the heating device to heat the first liquid; and when the temperature of the first liquid reaches the target temperature, controlling the conveying device to extract the first liquid and convey the first liquid to the acceleration device.

[0029] In this technical solution, after obtaining the beverage preparation instruction, the target temperature can also be determined through the beverage preparation instruction. Before controlling the conveying device to work, the first liquid to be drawn by the conveying device is heated by the heating device. When the temperature of the first liquid is heated to the target temperature, it indicates that the temperature of the first liquid has met the requirements for microbubble preparation. Then, the conveying device is controlled to deliver the first liquid to the accelerating device, so that the temperature of the microbubbles generated in the accelerating device can meet the cooking requirements.

[0030] Taking the making of hot coffee as an example, the coffee liquid, which serves as the base, is at a relatively high temperature before the microbubble layer is introduced into the cup. If a low-temperature microbubble layer is introduced directly at this point, the coffee temperature will drop, affecting the taste. To address this, by controlling the heating device so that the outlet of the acceleration device can output a high-temperature microbubble layer, the temperature of the microbubble layer can be prevented from affecting the temperature of the beverage.

[0031] Taking iced coffee making as an example, the target temperature for iced coffee is relatively low. Since the initial temperature of the first liquid is higher than the target temperature, there is no need to control the heating device. The first liquid directly impacts the gas introduced by the air intake device within the acceleration device to output microbubbles. Furthermore, compared to the steam foaming process in related technologies, the microbubbles produced in this application have a relatively low temperature, close to the initial temperature of the first liquid. When introduced into the substrate, they do not cause a significant temperature rise in the substrate solution, thereby reducing the amount of ice needed and improving the quality of the iced coffee.

[0032] In some technical solutions of the present invention, optionally, after the step of controlling the air intake device to deliver gas into the acceleration device, the control method further includes: controlling the food processor to issue a prompt message; and, under the condition of satisfying preset conditions, controlling the conveying device to extract the second liquid and deliver the second liquid to the acceleration device; wherein, the first liquid is the liquid required for foaming, and the second liquid is the liquid required for cleaning.

[0033] In this technical solution, after the microbubbles are prepared, the food processor is controlled to issue a prompt message. This prompt message can be an audio-visual message or a push message sent to the customer terminal. The prompt message is used to remind the user to provide a second liquid to the delivery device for self-cleaning.

[0034] After issuing a prompt message, and under preset conditions, the system controls the conveying device to extract a second liquid and deliver it to the acceleration device. This second liquid, distinct from the first liquid, is used to clean the pipes within the conveying and acceleration devices. Specifically, clean water or a cleaning solution can be selected as the second liquid. During the high-speed flow of the liquid within the conveying and acceleration devices, the first liquid adhering to the inner walls is flushed down, thus achieving self-cleaning of the conveying and acceleration devices. This prevents bacterial growth inside the food processor, avoids unpleasant odors, and ultimately improves the practicality and safety of the food processor, providing convenience for users.

[0035] Specifically, the preset conditions include the user manually operating the food processor to issue a cleaning command, as well as the trigger conditions after the user successfully installs the clean water tank.

[0036] In some technical solutions of the present invention, optionally, the food processor includes a cooking chamber, a conveying device for extracting a first liquid from the cooking chamber, and an accelerating device for conveying microbubbles into the cooking chamber; or the food processor further includes a liquid storage chamber, a conveying device for extracting a first liquid from the liquid storage chamber, and an accelerating device for conveying microbubbles into the cooking chamber.

[0037] In this technical solution, the conveying device is connected to the cooking chamber and is inserted below the liquid surface. During the foaming process, the conveying device draws liquid from the cooking chamber. The liquid is accelerated by an accelerator and then shears the gas introduced by the air intake device, generating microbubbles. Finally, the microbubbles are introduced into the cooking chamber through the accelerator. As microbubbles are continuously introduced, the conveying device not only draws in liquid from the cooking chamber but also draws in some microbubbles, causing these microbubbles to be aerated a second time. This further reduces the size of the bubbles, increases the density of the bubble layer, and prolongs the existence time of the bubble layer.

[0038] Therefore, by connecting the inlet of the conveying device to the cooking chamber, it is possible to achieve the circulation and frothing of microbubbles, thereby gradually reducing the diameter of the microbubbles and achieving the technical effect of improving the quality of beverages.

[0039] In another embodiment, the main body also includes a liquid storage chamber for storing liquid. The inlet of the conveying device is connected to the liquid storage chamber, allowing the conveying device to directly extract the liquid from the storage chamber. Compared to the above-mentioned circulating frothing scheme, this scheme is suitable for beverages where the first liquid and the base are different. For example, in preparing milk coffee, the cooking chamber contains coffee liquid. The conveying device extracts milk from the storage chamber and, through an acceleration device and an air intake device, forms microbubbles with a diameter of less than 100 μm. Finally, these microbubbles formed from the milk are conveyed to the top of the coffee liquid, thus creating a milk coffee with distinct layers.

[0040] Therefore, it can be seen that by setting up a liquid storage chamber and connecting the second end of the first pipeline to the liquid storage chamber, it is beneficial to improve the separation of layers in multi-layer beverages, thereby achieving the technical effect of improving the quality of beverages.

[0041] A second aspect of the present invention provides a control device for a food processor, the food processor including a conveying device, an accelerating device and an air intake device, the control device including: a first control module, which controls the conveying device to draw a first liquid and deliver the first liquid to the accelerating device based on a beverage preparation instruction; and a second control module, which controls the air intake device to deliver gas into the accelerating device.

[0042] In this technical solution, the food processor includes a conveying device, an accelerating device, and an air intake device. One end of the accelerating device is connected to the conveying device, and the other end of the accelerating device is connected to the cooking chamber. The air intake device is connected to the accelerating device.

[0043] Based on this, the control device of the food processor includes a first control module and a second control module.

[0044] When the food processor determines that foaming is required based on the received beverage preparation instructions, the first control module controls the conveying device to extract the first liquid and deliver it to the acceleration device. The first liquid, used for foaming, can be a protein-rich solution such as milk or soy milk. After being delivered to the acceleration device, the device accelerates the first liquid, allowing it to flow at high speed within the device. Following the first control module's control of the conveying device to deliver the first liquid to the acceleration device, the second control module controls the air intake device to deliver gas into the acceleration device.

[0045] The first liquid, after being accelerated and flowing at high speed, can shear the gas delivered by the air intake device. Under the shearing and mixing action between the high-speed liquid and gas, microbubbles with a diameter of less than 100μm can be generated. Finally, the microbubbles are introduced into the cooking chamber through the acceleration device and form a dense and long-lasting microbubble layer on the liquid surface in the cooking chamber.

[0046] By limiting the aforementioned control device, on the one hand, the amount of bubbles accumulating above the liquid can be increased by reducing the size of the bubbles, thereby improving the smoothness of the bubble layer on top of the food and providing users with a creamy texture. On the other hand, the duration of bubble existence can be extended by reducing the size of the bubbles, allowing the bubble layer on top of the food to persist for a longer period.

[0047] Therefore, this application solves the technical problems of poor bubble fineness and poor stability in related technologies by controlling the food processor to produce microbubbles with a diameter of less than 100μm, thereby achieving the technical effect of improving the foaming quality of the food processor and improving the quality of the beverages produced.

[0048] A third aspect of the present invention provides a control device for a food processor, the control device comprising: a memory storing a program or instructions; and a processor executing the program or instructions stored in the memory to implement the steps of the control method for the food processor as described in any of the above technical solutions.

[0049] This technical solution proposes a control device for a food processor. This control device includes a memory and a processor. The processor executes the programs or instructions stored in the memory to implement the food processor control method described in any of the aforementioned technical solutions. Therefore, this food processor control device possesses the advantages of the food processor control methods described in any of the aforementioned technical solutions and can achieve the technical effects achievable by the food processor control methods described in any of the aforementioned technical solutions. To avoid repetition, further details are omitted here.

[0050] A fourth aspect of the present invention provides a step in which a program or instructions are stored on a readable storage medium, and when the program or instructions are executed by a processor, the program or instructions implement the control method as described in any of the above technical solutions.

[0051] This technical solution proposes a readable storage medium that stores a program or instructions. When executed by a processor, the program or instructions can implement the steps of the food processor control method described in any of the aforementioned technical solutions. Therefore, this readable storage medium possesses the advantages of the food processor control methods described in any of the aforementioned technical solutions and can achieve the technical effects achievable by these methods. To avoid repetition, further details are omitted here.

[0052] A fifth aspect of the present invention provides a food processor, comprising: a control device for a food processor as described in any of the above technical solutions, and / or a readable storage medium as described in the above technical solutions.

[0053] This technical solution proposes a food processor that includes the control device described in any of the above-mentioned technical solutions, and / or the readable storage medium described in the above-mentioned technical solutions. Therefore, this food processor possesses the advantages of the control device described in any of the above-mentioned technical solutions, and can achieve the technical effects achievable by the control device described in any of the above-mentioned technical solutions, and / or the food processor possesses the advantages of the readable storage medium described in the above-mentioned technical solutions, and can achieve the technical effects achievable by the readable storage medium described in the above-mentioned technical solutions. To avoid repetition, further details are omitted here.

[0054] In some technical solutions of the present invention, the food processor may optionally include: a main body, the main body including a cooking cavity; a conveying device disposed on the main body; an accelerating device, the accelerating device connecting the conveying device and the cooking cavity, the conveying device being used to convey liquid into the accelerating device, the accelerating device being used to accelerate the liquid; and an air intake device connected to the accelerating device, the air intake device being used to introduce gas into the accelerated liquid.

[0055] In this technical solution, the food processor includes a main body, which serves as the main frame structure of the food processor and is used to position, support, and protect other structures on the food processor. A cooking cavity is formed within the main body to hold food.

[0056] In this technical solution, the microbubble generating component can generate microbubbles inside, and then inject the generated microbubbles above the liquid surface to form a bubble layer on the surface of the beverage.

[0057] Specifically, the microbubble generating component includes a conveying device, an accelerating device, and an air intake device. One end of the accelerating device is connected to the conveying device, the other end of the accelerating device is connected to the cooking cavity, and the air intake device is connected to the accelerating device.

[0058] During operation, the conveying device delivers liquid to the accelerating device, which increases the flow rate of the liquid. The air intake device introduces air into the liquid after it has been successfully accelerated. The high-speed flowing liquid, after acceleration, shears the gas introduced by the air intake device. Under the shearing and mixing action between the high-speed liquid and gas, microbubbles with a diameter of less than 100μm are generated. These microbubbles are then introduced into the cooking chamber through the accelerating device, forming a dense and long-lasting bubble layer on the liquid surface within the cooking chamber. This solves the technical problems of poor bubble fineness and stability in related technologies, thereby improving the foaming quality of the food processor and the quality of the prepared beverage.

[0059] Optionally, in some technical solutions of the present invention, the food processor further includes a heating device, which is disposed on the conveying device or the accelerating device, and is used to heat the liquid.

[0060] In this technical solution, the microbubble generating component also includes a heating device, which is installed on at least one of the conveying device and the accelerating device. When turned on, the heating device can heat the liquid or microbubbles, enabling the microbubble generating component to output high-temperature microbubbles, thereby meeting the diverse needs of beverages and improving the user experience.

Detailed Implementation

[0076] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0077] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0078] The following reference Figures 1 to 11 A control method, apparatus, storage medium, and food processor for a food processor according to some embodiments of the present invention are described.

[0079] like Figure 1 As shown, one embodiment of the present invention proposes a control method for a food processor, the food processor including a conveying device, an accelerating device, and an air intake device, the control method including:

[0080] Step 102: Based on the beverage preparation instruction, control the conveying device to extract the first liquid and convey the first liquid to the acceleration device;

[0081] Step 104: Control the air intake device to deliver gas into the acceleration device so that the gas enters the first liquid and forms bubbles.

[0082] In this embodiment, the food processor includes a conveying device, an accelerating device, and an air intake device. One end of the accelerating device is connected to the conveying device, and the other end of the accelerating device is connected to the cooking chamber. The air intake device is connected to the accelerating device.

[0083] During operation, the conveying device is used to deliver liquid into the acceleration device, which can increase the flow rate of the delivered liquid. The air intake device can introduce air into the liquid after it has been successfully accelerated by the acceleration device.

[0084] Based on this, the control method for the food processor is as follows:

[0085] When the food processor is determined to need foaming based on the received beverage preparation instructions, the control conveyor draws in a first liquid and delivers it to the acceleration device. This first liquid, used for foaming, can be a protein-rich solution such as milk or soy milk. After being delivered to the acceleration device, the device accelerates the first liquid, allowing it to flow at high speed within the device. Following the delivery of the first liquid to the acceleration device, the control air intake device then delivers gas into the acceleration device.

[0086] The first liquid, after being accelerated and flowing at high speed, can shear the gas delivered by the air intake device. Under the shearing and mixing action between the high-speed liquid and gas, microbubbles with a diameter of less than 100μm can be generated. Finally, the microbubbles are introduced into the cooking chamber through the acceleration device and form a dense and long-lasting microbubble layer on the liquid surface in the cooking chamber.

[0087] By limiting the above control methods, on the one hand, the amount of bubbles accumulating above the liquid can be increased by reducing the size of the bubbles, thereby improving the smoothness of the bubble layer on top of the food and providing users with a creamy texture. On the other hand, the duration of bubble existence can be extended by reducing the size of the bubbles, allowing the bubble layer on top of the food to persist for a longer period.

[0088] For example, in making milk coffee, if the diameter of the bubbles in the bubble layer is around 2mm in a 20cm deep beverage, the duration of the bubbles is about 0.1 seconds. When the microbubbles with a diameter of around 20μm are produced by the above control method in this application, the duration of the microbubbles is about 1000 seconds.

[0089] Therefore, this application solves the technical problems of poor bubble fineness and poor stability in related technologies by controlling the food processor to produce microbubbles with a diameter of less than 100μm, thereby achieving the technical effect of improving the foaming quality of the food processor and improving the quality of the beverages produced.

[0090] like Figure 2 As shown, in some embodiments of the present invention, optionally, the step of controlling the intake device to deliver gas into the acceleration device includes:

[0091] Step 202: Determine the foaming density and foaming amount according to the beverage preparation instructions, and determine the target flow rate and target duration based on the foaming density and foaming amount;

[0092] Step 204: When the working time of the conveying device reaches the preset time, control the air intake device to deliver gas into the acceleration device at a flow rate of the target flow rate.

[0093] Step 206: When the working time of the air intake device reaches the target time, control the conveying device and the air intake device to stop working.

[0094] In this embodiment, the step of controlling the intake device to deliver gas into the acceleration device specifically includes:

[0095] After receiving the beverage preparation instruction, the corresponding target duration is determined based on the foaming density and foaming amount contained in the beverage preparation instruction. The higher the foaming density, the denser the foam layer and the longer the residence time. Conversely, the lower the foaming density, the sparser the foam layer and the shorter the residence time. The foaming amount affects the thickness of the foam layer. The higher the foaming amount, the thicker the foam layer.

[0096] If the delivery time of the first liquid from the conveying device to the acceleration device reaches the preset time, it indicates that the first liquid has reached the foaming position. Then, the air intake device is controlled to deliver gas into the acceleration device, and the flow rate of the gas delivered into the acceleration device is controlled by controlling the power of the air intake device to achieve the target flow rate. By controlling the flow rate of the gas impacted by the first liquid, the density of the formed bubbles can be changed to ensure that the produced microbubble layer can meet the cooking requirements.

[0097] The preset time corresponds to the time required for the first liquid to flow to the foaming area. By controlling the conveying component to work for the preset time, it can be ensured that the gas delivered by the air intake device to the acceleration device can be impacted by the high-speed flowing first liquid, thus avoiding the acceleration device from outputting airflow at the beginning of operation and achieving the technical effect of improving the reliability of the food processor.

[0098] During the operation of the air intake device, microbubbles are continuously produced at the outlet of the acceleration device. When the air intake device reaches the target operating time, it indicates that the total amount of microbubbles produced has met the requirements. At this point, the conveying device and the air intake device are stopped to complete the foaming operation. By controlling the operating time of the air intake device and the conveying device according to the target time, the thickness of the microbubble layer can be made to meet the requirements of the corresponding beverage, avoiding the impact on the quality of the beverage due to insufficient microbubble layer thickness.

[0099] In summary, by limiting the above control methods, the food processor can accurately control the foaming process, thereby improving the control precision of the food processor, enhancing the quality of the cooked food, and increasing the intelligence level of the food processor.

[0100] like Figure 3 As shown, in some embodiments of the present invention, optionally, the food processor further includes a heating device, and before the step of controlling the conveying device to draw in the first liquid and convey the first liquid to the accelerating device, the control method further includes:

[0101] Step 302: Determine the target temperature according to the beverage preparation instructions;

[0102] Step 304: Control the heating device to heat the first liquid;

[0103] Step 306: When the temperature of the first liquid reaches the target temperature, control the conveying device to extract the first liquid and convey the first liquid to the acceleration device.

[0104] In this embodiment, after obtaining the beverage preparation instruction, the target temperature can also be determined through the beverage preparation instruction. Before controlling the conveying device to work, the first liquid to be drawn by the conveying device is heated by the heating device. When the temperature of the first liquid is heated to the target temperature, it indicates that the temperature of the first liquid has met the requirements for microbubble preparation. Then, the conveying device is controlled to deliver the first liquid to the accelerating device so that the temperature of the microbubbles generated in the accelerating device can meet the cooking requirements.

[0105] Taking the making of hot coffee as an example, the coffee liquid, which serves as the base, is at a relatively high temperature before the microbubble layer is introduced into the cup. If a low-temperature microbubble layer is introduced directly at this point, the coffee temperature will drop, affecting the taste. To address this, by controlling the heating device so that the outlet of the acceleration device can output a high-temperature microbubble layer, the temperature of the microbubble layer can be prevented from affecting the temperature of the beverage.

[0106] Taking iced coffee making as an example, the target temperature for iced coffee is relatively low. Since the initial temperature of the first liquid is higher than the target temperature, there is no need to control the heating device. The first liquid directly impacts the gas introduced by the air intake device within the acceleration device to output microbubbles. Furthermore, compared to the steam foaming process in related technologies, the microbubbles produced in this application have a relatively low temperature, close to the initial temperature of the first liquid. When introduced into the substrate, they do not cause a significant temperature rise in the substrate solution, thereby reducing the amount of ice needed and improving the quality of the iced coffee.

[0107] like Figure 4 As shown, in some embodiments of the present invention, optionally, after the step of controlling the intake device to deliver gas into the acceleration device, the control method further includes:

[0108] Step 402: Control the food processor to issue a prompt message;

[0109] Step 404: Under the condition that the preset conditions are met, control the conveying device to extract the second liquid and convey the second liquid to the acceleration device;

[0110] The first liquid is the liquid required for foaming, and the second liquid is the liquid required for cleaning.

[0111] In this embodiment, after the microbubbles are prepared, the food processor is controlled to issue a prompt message. This prompt message can be an audio-visual message or a push message sent to the client terminal. The prompt message is used to remind the user to provide a second liquid to the delivery device for self-cleaning.

[0112] After issuing a prompt message, and under preset conditions, the system controls the conveying device to extract a second liquid and deliver it to the acceleration device. This second liquid, distinct from the first liquid, is used to clean the pipes within the conveying and acceleration devices. Specifically, clean water or a cleaning solution can be selected as the second liquid. During the high-speed flow of the liquid within the conveying and acceleration devices, the first liquid adhering to the inner walls is flushed down, thus achieving self-cleaning of the conveying and acceleration devices. This prevents bacterial growth inside the food processor, avoids unpleasant odors, and ultimately improves the practicality and safety of the food processor, providing convenience for users.

[0113] Specifically, the preset conditions include the user manually operating the food processor to issue a cleaning command, as well as the trigger conditions after the user successfully installs the clean water tank.

[0114] In some embodiments of the present invention, the food processor may optionally include a cooking chamber, a conveying device for extracting a first liquid from the cooking chamber, and an accelerating device for conveying microbubbles into the cooking chamber; or the food processor may also include a liquid storage chamber, a conveying device for extracting a first liquid from the liquid storage chamber, and an accelerating device for conveying microbubbles into the cooking chamber.

[0115] In this embodiment, the conveying device is connected to the cooking chamber and is specifically inserted below the liquid surface. During the foaming process, the conveying device draws liquid from the cooking chamber. The liquid is accelerated by an accelerator and then shears the gas introduced by the air intake device, generating microbubbles. Finally, the microbubbles are introduced into the cooking chamber by the accelerator. As microbubbles are continuously introduced, the conveying device not only draws in liquid from the cooking chamber but also draws in some microbubbles, causing these microbubbles to be aerated a second time, thereby further reducing the size of the bubbles, increasing the density of the bubble layer, and prolonging the existence time of the bubble layer.

[0116] Therefore, by connecting the inlet of the conveying device to the cooking chamber, it is possible to achieve the circulation and frothing of microbubbles, thereby gradually reducing the diameter of the microbubbles and achieving the technical effect of improving the quality of beverages.

[0117] In another embodiment, the main body also includes a liquid storage chamber for storing liquid. The inlet of the conveying device is connected to the liquid storage chamber, allowing the conveying device to directly extract the liquid from the storage chamber. Compared to the above-mentioned circulating frothing scheme, this scheme is suitable for beverages where the first liquid and the base are different. For example, in preparing milk coffee, the cooking chamber contains coffee liquid. The conveying device extracts milk from the storage chamber and, through an acceleration device and an air intake device, forms microbubbles with a diameter of less than 100 μm. Finally, these microbubbles formed from the milk are conveyed to the top of the coffee liquid, thus creating a milk coffee with distinct layers.

[0118] Therefore, it can be seen that by setting up a liquid storage chamber and connecting the second end of the first pipeline to the liquid storage chamber, it is beneficial to improve the separation of layers in multi-layer beverages, thereby achieving the technical effect of improving the quality of beverages.

[0119] In one embodiment of this application, the inlet of the conveying device is connected to the cooking chamber, and the conveying device draws the first liquid from the cooking chamber, with the corresponding cyclic whipping process as follows:

[0120] Step 1 (Preparation): The user selects the milk coffee function key, and the system identifies the attributes of the milk foam required by the milk coffee function key: foam density X, foam volume V1, target temperature T1. After extracting the coffee, the microbubble generator is activated.

[0121] Step 2 (Heating on): The user or machine adds milk, with a volume of V2. Then the heating device on the outside of the milk cup and pipes begins to heat to the target temperature T1.

[0122] Step 3 (Milk Suction): When the milk and pipe temperature reach the target temperature T1, the conveying device starts working, and the milk is fed into the acceleration device at a flow rate of q1.

[0123] Step 4 (Gas Introducing for Foaming): The volume of the pipe before the foaming area is V2. When the working time of the conveying device is t1 ≥ V2 ÷ q1, the air intake device starts working, introducing gas into the acceleration device at a target flow rate of q2. Where q2 ÷ q1 = X.

[0124] Step 5 (Foaming Completed): When the frothing time t2 ≥ V2 ÷ q1, or when the user manually selects to stop frothing, the conveying device stops working and transfers milk foam of volume V1. After the milk foam is completed, it is transferred to the coffee.

[0125] Step 6 (Cleaning): After the user removes the milk foam, instruct them to place it in a cup of clean water. The conveying device then starts working, supplying water into the accelerator at a flow rate of q3. The total volume of the pipelines of the conveying device and the accelerator is V3. Therefore, the cleaning time of the conveying device is t3 ≥ 5 × V3 ÷ q3. Where q3 > q1, this ensures that the pipeline is thoroughly rinsed.

[0126] In one specific embodiment, the cooking process for milk coffee is as follows:

[0127] Step 1: The user pours milk into a milk cup, selects the cappuccino coffee function, identifies the milk foam properties: X=3, V1=0.3L, T1=70℃, and after extracting the coffee, starts the microbubble generator.

[0128] Step 2: The user or the machine adds 0.3L of milk, after which the milk cup and the heating element on the outside of the pipe will start heating to 70℃.

[0129] Step 3: When the milk and pipe temperature reach 70°C, the conveying device starts working, feeding the milk into the acceleration device at a flow rate of 0.6 (L / min).

[0130] Step 4: If the volume of the pipe before the foaming area is 0.02L, then when the working time of the conveying device reaches 2s, the air intake device starts to work, and the gas is introduced into the acceleration device at a flow rate of 1.8 (L / min).

[0131] Step 5: When the frothing time is 30 seconds, or when the user manually selects to stop frothing, the conveyor stops working and transfers 0.3L of milk foam. After the milk foam is completed, it is transferred to the coffee.

[0132] Step 6: After the user removes the milk foam, prompt the user to put it into a cup of clean water. The conveying device starts working and flows water into the acceleration device at a flow rate of 0.8 (L / min). The total volume of the pipelines of the conveying device and the acceleration device is 0.04L. The cleaning time of the conveying device is 20s.

[0133] In one embodiment of this application, the inlet of the conveying device is connected to the liquid storage chamber, and the conveying device draws the first liquid from the liquid storage chamber. The corresponding non-circulating emulsification process is as follows:

[0134] Step 1 (Preparation): The user selects the milk coffee function key, and the system identifies the attributes of the milk foam required by the milk coffee function key: foam density X, foam volume V1, target temperature T1. After extracting the coffee, the microbubble generator is activated.

[0135] Step 2 (Turn on heating): The external heating device of the milk cup and pipe begins to heat up to the target temperature T1.

[0136] Step 3 (Milk Suction): When the milk and pipe temperature reach the target temperature T1, the conveying device starts working, and the milk is fed into the acceleration device at a flow rate of q1.

[0137] Step 4 (Gas Introducing for Foaming): The volume of the pipe before the foaming area is V2. When the working time of the conveying device is t1 ≥ V2 ÷ q1, the air intake device starts working, introducing gas into the acceleration device at a target flow rate of q2. During the foaming process, the flow rate of the milk foam mixed in the first liquid is q3; preferably, (q2 + q3) ÷ (q1 - q3) = X.

[0138] Step 5 (Foaming Completed): When the frothing time t2≥V2÷q1, or when the user manually selects to stop frothing, the conveying device stops working, and the milk foam frothing is completed. The milk foam can be transferred to the coffee after the milk foam is completed or during the milk foam preparation process.

[0139] Step 6 (Cleaning): After the user removes the milk foam, instruct them to place it in a cup of clean water. The conveying device then starts working, supplying water into the accelerator at a flow rate of q3. The total volume of the pipelines of the conveying device and the accelerator is V3. Therefore, the cleaning time of the conveying device is t3 ≥ 5 × V3 ÷ q3. Where q3 > q1, this ensures that the pipeline is thoroughly rinsed.

[0140] In one specific embodiment, the cooking process for milk coffee is as follows:

[0141] Step 1: The user pours milk into a milk cup, selects the latte function, identifies the milk foam properties: X=1, V1=0.3L, T1=70℃, and after extracting the coffee, starts the microbubble generator.

[0142] Step 2: The heating element on the outside of the milk cup and pipe begins to heat up to the set temperature of 70°C.

[0143] Step 3: When the milk and pipe temperature reach 70°C, the conveying device starts working, feeding the milk into the acceleration device at a flow rate of 0.3 (L / min).

[0144] Step 4: If the volume of the pipe before the foaming area is 0.02L, then when the conveying device has been working for 2 seconds, the air intake device will start working and introduce gas into the acceleration device at a flow rate of 0.1 (L / min).

[0145] Step 5: When the frothing time is 45 seconds, or when the user manually selects to stop frothing, the conveying device stops working, and the milk foam frothing is completed. The milk foam can be transferred to the coffee after it is completed or during the milk foam preparation process.

[0146] Step 6: After the user removes the milk foam, prompt the user to put it into a cup of clean water. The conveying device starts working and flows water into the acceleration device at a flow rate of 0.4 (L / min). The total volume of the pipelines of the conveying device and the acceleration device is 0.04L. The cleaning time of the conveying device is 30s.

[0147] like Figure 5As shown, one embodiment of the present invention provides a control device 500 for a food processor. The food processor includes a conveying device, an accelerating device, and an air intake device. The control device includes: a first control module 502, which controls the conveying device to extract a first liquid and deliver the first liquid to the accelerating device based on a beverage preparation command; and a second control module 504, which controls the air intake device to deliver gas into the accelerating device.

[0148] In this embodiment, the food processor includes a conveying device, an accelerating device, and an air intake device. One end of the accelerating device is connected to the conveying device, and the other end of the accelerating device is connected to the cooking chamber. The air intake device is connected to the accelerating device.

[0149] During operation, the conveying device is used to deliver liquid into the acceleration device, which can increase the flow rate of the delivered liquid. The air intake device can introduce air into the liquid after it has been successfully accelerated by the acceleration device.

[0150] Based on this, the control device 500 of the food processor includes a first control module 502 and a second control module 504.

[0151] When the food processor determines that foaming is required based on the received beverage preparation instructions, the first control module 502 controls the conveying device to extract the first liquid and deliver it to the acceleration device. The first liquid is used for foaming and can be a protein-rich solution such as milk or soy milk. After being delivered to the acceleration device, the acceleration device accelerates the first liquid, allowing it to flow at high speed within the device. After the first control module 502 controls the conveying device to deliver the first liquid to the acceleration device, the second control module 504 controls the air intake device to deliver gas into the acceleration device.

[0152] The first liquid, after being accelerated and flowing at high speed, can shear the gas delivered by the air intake device. Under the shearing and mixing action between the high-speed liquid and gas, microbubbles with a diameter of less than 100μm can be generated. Finally, the microbubbles are introduced into the cooking chamber through the acceleration device and form a dense and long-lasting microbubble layer on the liquid surface in the cooking chamber.

[0153] By limiting the aforementioned control device, on the one hand, the amount of bubbles accumulating above the liquid can be increased by reducing the size of the bubbles, thereby improving the smoothness of the bubble layer on top of the food and providing users with a creamy texture. On the other hand, the duration of bubble existence can be extended by reducing the size of the bubbles, allowing the bubble layer on top of the food to persist for a longer period.

[0154] Therefore, this application solves the technical problems of poor bubble fineness and poor stability in related technologies by controlling the food processor to produce microbubbles with a diameter of less than 100μm, thereby achieving the technical effect of improving the foaming quality of the food processor and improving the quality of the beverages produced.

[0155] like Figure 6 As shown, one embodiment of the present invention provides a control device 600 for a food processor. The control device 600 includes: a memory 602 storing programs or instructions; and a processor 604 executing the programs or instructions stored in the memory 602 to implement the steps of the control method for the food processor as described in any of the above embodiments.

[0156] In this embodiment, a control device 600 for a food processor is proposed. The control device 600 includes a memory 602 and a processor 604. The processor 604 executes the programs or instructions stored in the memory 602 to implement the control method of the food processor in any of the above embodiments. Therefore, the control device 600 possesses the advantages of the control method of the food processor in any of the above embodiments and can achieve the technical effects achievable by the control method of the food processor in any of the above embodiments. To avoid repetition, further details are omitted here.

[0157] One embodiment of the present invention provides a readable storage medium storing a program or instructions, which, when executed by a processor, implement the steps of the control method as described in any of the above embodiments.

[0158] In this embodiment, a readable storage medium is proposed, which stores a program or instructions. When executed by a processor, the program or instructions can implement the steps of the food processor control method described in any of the above embodiments. Therefore, this readable storage medium possesses the advantages of the food processor control method described in any of the above embodiments and can achieve the technical effects achievable by the food processor control method described in any of the above embodiments. To avoid repetition, further details are omitted here.

[0159] One embodiment of the present invention provides a food processor, which includes: a control device for the food processor as described in any of the above embodiments, and / or a readable storage medium as described in the above embodiments.

[0160] In this embodiment, a food processor is proposed that includes the control device of any of the above embodiments and / or the readable storage medium of the above embodiments. Therefore, the food processor possesses the advantages of the control device of any of the above embodiments and can achieve the technical effects that the control device of any of the above embodiments can achieve, and / or the food processor possesses the advantages of the readable storage medium of the above embodiments and can achieve the technical effects that the readable storage medium of the above embodiments can achieve. To avoid repetition, further details are omitted here.

[0161] like Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments of the present invention, optionally, the food processor 100 further includes: a body 110, the body 110 including a cooking chamber 1102; a conveying device 124 disposed on the body 110; an accelerating device 126 connected to the conveying device 124 and the cooking chamber 1102, the conveying device 124 being used to convey liquid into the accelerating device 126, the accelerating device 126 being used to accelerate the liquid; and an air intake device 128 connected to the accelerating device 126, the air intake device 128 being used to introduce gas into the accelerated liquid.

[0162] In this embodiment, the food processor 100 includes a body 110, which is the main frame structure of the food processor 100. The body 110 is used to position, support, and protect other structures on the food processor 100. A cooking cavity 1102 is formed in the body 110, which is used to contain food.

[0163] In this embodiment, a second microbubble generating component 120 is proposed, which can generate microbubbles internally and then inject the generated microbubbles above the liquid surface to form a bubble layer on the surface of the beverage.

[0164] Specifically, the microbubble generating assembly 120 includes a conveying device 124, an accelerating device 126, and an air intake device 128. One end of the accelerating device 126 is connected to the conveying device 124, and the other end of the accelerating device 126 is connected to the cooking cavity 1102. The air intake device 128 is connected to the accelerating device 126.

[0165] During operation, the conveying device 124 delivers liquid to the accelerating device 126, which increases the flow rate of the delivered liquid. The air intake device 128 introduces air into the liquid after it has been successfully accelerated by the accelerating device 126. The high-speed flowing liquid, after acceleration, shears the gas delivered by the air intake device 128. Under the shearing and mixing action between the high-speed liquid and gas, microbubbles with a diameter of less than 100 μm are generated. These microbubbles are then introduced into the cooking chamber 1102 through the accelerating device 126, forming a dense and long-lasting bubble layer on the liquid surface within the cooking chamber 1102. This solves the technical problems of poor bubble fineness and stability in related technologies, thereby improving the foaming quality of the food processor 100 and enhancing the quality of the prepared beverage.

[0166] Based on this, the combined structure of the conveying device 124, the accelerating device 126 and the air intake device 128 can also realize the low-temperature generation of microbubbles.

[0167] Specifically, many related technologies involve heating the liquid during the foaming process. Taking milk foaming as an example, the milk needs to be heated with high-temperature steam or a heating rod during the whipping process to improve the foaming properties of milk proteins and reduce the surface tension of the milk, ensuring that the milk foam is in a relatively fine and stable state.

[0168] However, with the increasing youthfulness of the modern milk coffee market, more and more people are abandoning hot drinks in favor of iced and cold drinks. Heating plays a crucial role in improving the quality of milk foam, which is key to successful steam frothing. When customers want cold drinks, ice cubes need to be heated in the beverage to counteract the heat generated during the high-temperature frothing process, affecting the drink's concentration and compromising its quality. Furthermore, the high-temperature steam introduced during the process also mixes with liquid, further reducing the drink's concentration and quality.

[0169] In response, this application utilizes a high-speed liquid shearing gas flow method to directly produce a dense and long-lasting microbubble layer without the need for a heating process. This allows users to obtain low-temperature beverages without the need for ice to cool them down, thus avoiding the loss of beverage concentration due to ice. Furthermore, in the process of preparing microbubbles, this embodiment directly shears the gas using high-speed flowing milk without introducing other liquids, ensuring that the beverage concentration is not compromised. This achieves the technical effect of improving beverage quality and enhancing the user experience.

[0170] like Figure 8 As shown, in some embodiments of the present invention, the food processor 100 may optionally include a heating device 129, which is disposed on the conveying device 124 or the accelerating device 126, and is used to heat liquid.

[0171] In this embodiment, the microbubble generating component 120 further includes a heating device 129, which is disposed on at least one of the conveying device 124 and the accelerating device 126. When turned on, the heating device 129 can heat the liquid or microbubbles, enabling the microbubble generating component to output high-temperature microbubbles, thereby meeting the diverse needs of beverages and improving the user experience.

[0172] like Figure 8 and Figure 9 As shown, in some embodiments of the present invention, optionally, the conveying device 124 includes: a pump body 1242, the pump body 1242 being disposed on the body 110, the pump body 1242 including an inlet 12422 and an outlet 12424; a first pipe 1244, the first end of the first pipe 1244 being connected to the inlet 12422; and a second pipe 1246, the first end of the second pipe 1246 being connected to the outlet 12424, and the second end of the second pipe 1246 being connected to the acceleration device 126.

[0173] In this embodiment, the conveying device 124 includes a pump body 1242, a first pipeline 1244, and a second pipeline 1246.

[0174] The pump body 1242 is provided with an inlet 12422 and an outlet 12424. The first end of the first pipe 1244 is connected to the inlet 12422 on the pump body 1242, and the second end of the first pipe 1244 is inserted into the liquid. The first end of the second pipe 1246 is connected to the outlet 12424, and the second end of the second pipe 1246 is connected to the acceleration device 126.

[0175] During operation, the pump body 1242 draws liquid in through the first pipe 1244, and after pressurization and acceleration, delivers the liquid to the acceleration device 126 through the second pipe 1246. This enables automatic water supply to the acceleration device 126, achieving automated microbubble generation and thus enhancing the automation level of the food processor 100. Furthermore, compared to actively supplying water to the acceleration device 126, the pump body 1242 allows for precise control of the liquid delivery volume, thereby accurately controlling the foam output and actual foam production, further enhancing the intelligence level of the food processor 100.

[0176] like Figure 8 As shown, in some embodiments of the present invention, optionally, the second end of the first pipe 1244 is connected to the cooking chamber 1102, and the pump body 1242 draws liquid from the cooking chamber 1102 through the first pipe 1244; or the body 110 further includes a liquid storage chamber 1104, the second end of the first pipe 1244 is connected to the liquid storage chamber 1104, and the pump body 1242 draws liquid from the liquid storage chamber 1104 through the first pipe 1244.

[0177] In this embodiment, the second end of the first pipe 1244 is connected to the cooking chamber 1102, specifically inserted below the liquid surface. After the microbubble generating component is turned on, the pump body 1242 draws liquid from the cooking chamber 1102 through the first pipe 1244. The liquid is accelerated by the acceleration device 126 and shears the gas introduced by the air intake device 128, generating microbubbles. Finally, the microbubbles are introduced into the cooking chamber 1102 by the acceleration device 126. As microbubbles are continuously introduced, the first pipe 1244 not only draws in liquid from the cooking chamber 1102, but also draws in some microbubbles, causing these microbubbles to be agitated a second time, thereby further reducing the size of the bubbles, increasing the density of the bubble layer, and prolonging the existence time of the bubble layer.

[0178] It can be seen that by connecting the second end of the first pipe 1244 to the cooking chamber 1102, the microbubbles can be circulated and whipped, thereby gradually reducing the diameter of the microbubbles and achieving the technical effect of improving the quality of the beverage.

[0179] like Figure 9 As shown, in another embodiment, the main body 110 is further provided with a liquid storage chamber 1104, which is used to store liquid. The second end of the first pipe 1244 is connected to the liquid storage chamber 1104, and the pump body 1242 can directly draw liquid from the liquid storage chamber 1104 through the first pipe 1244. Compared with the above-mentioned circulating frothing scheme, this scheme is suitable for beverages where the first liquid and the liquid at the bottom of the bubble layer are different. For example, when preparing milk coffee, the cooking chamber 1102 contains coffee liquid. The pump body 1242 draws milk from the liquid storage chamber 1104 through the first pipe 1244, and forms microbubbles with a diameter of less than 100μm through the acceleration device 126 and the air intake device 128. Finally, the microbubbles formed by this part of milk are transported to the top of the coffee liquid, thereby forming a milk coffee with distinct layers.

[0180] Therefore, by setting up a liquid storage chamber 1104 and connecting the second end of the first pipeline 1244 to the liquid storage chamber 1104, it is beneficial to improve the separation degree of multi-layer beverages, thereby achieving the technical effect of improving the quality of beverages.

[0181] like Figure 10 and Figure 11As shown, in some embodiments of the present invention, optionally, the acceleration device 126 includes: a third pipeline 1262, the first end of which is connected to the conveying device 124; the third pipeline 1262 includes an acceleration section 12622, the flow area of ​​which gradually decreases in the flow direction from the first end to the second end of the third pipeline 1262; the third pipeline 1262 also includes an air inlet 12624, which is located between the acceleration section 12622 and the second end of the third pipeline 1262, and the air intake device 128 is connected to the air inlet 12624.

[0182] In this embodiment, the acceleration device 126 includes a third pipe 1262, the first end of which is connected to the second end of the second pipe 1246, and the second end of the third pipe 1262 is connected to the cooking cavity 1102.

[0183] The third pipeline 1262 has an acceleration section 12622 with a gradually decreasing flow area in the middle section. According to the fluid characteristics, reducing the flow area can accelerate the fluid. Therefore, by setting the acceleration section 12622, the liquid can be accelerated to ensure that the liquid can form microbubbles by high-speed shearing of the gas.

[0184] Specifically, the third pipe 1262 also includes an air inlet 12624, which is located between the acceleration section 12622 and the second end of the third pipe 1262. The air inlet 12624 is connected to the air intake device 128. Gas enters the third pipe 1262 through the air inlet 12624. After the gas enters the air inlet 12624, the high-speed liquid accelerated by the acceleration section 12622 immediately shears the liquid to form microbubbles between the acceleration section 12622 and the second end of the third pipe 1262. Finally, the bubbles are injected into the cooking chamber 1102 under pressure from the second end of the third pipe 1262 to form a microbubble layer in the cooking chamber 1102.

[0185] Compared to the solution of accelerating liquid by using a booster pump, constructing an acceleration section 12622 with a gradually decreasing cross-sectional area in the third pipeline 1262 is less costly and more reliable, which helps to reduce the production cost of cooking equipment and can reduce the failure rate of the microbubble generating component 120.

[0186] like Figure 11 As shown, in some embodiments of the present invention, optionally, in the flow direction, the flow area at the beginning of the acceleration section 12622 is a first area, and the flow area at the end is a second area; the ratio of the first area to the second area is greater than or equal to 5 and less than or equal to 15.

[0187] Figure 11In the diagram, arrow a indicates the flow direction of the microbubbles, arrow b indicates the beginning of the acceleration section 12622, and arrow c indicates the end of the acceleration section 12622.

[0188] In this embodiment, the acceleration section 12622 includes a starting end and an ending end. The starting end is close to the first end of the third pipe 1262, and the ending end is close to the second end of the third pipe 1262. The liquid enters the acceleration section 12622 from the starting end, and after being accelerated by the acceleration section 12622, it is discharged from the ending end to the area where the air inlet 12624 is located.

[0189] Based on this, the circulation area at the beginning is the first area, and the circulation area at the end is the second area. The ratio of the first area to the second area must be greater than or equal to 5 and less than or equal to 15.

[0190] By limiting the ratio of the first area to the second area to be greater than or equal to 5, it can be ensured that the acceleration section 12622 can increase the flow rate of the liquid to a predetermined speed, ensuring that the liquid can generate microbubbles by shearing the gas, thereby achieving the technical effect of increasing bubble density and extending bubble existence time. By limiting the ratio of the first area to the second area to be less than or equal to 15, it is possible to avoid the flow area at the end being too small, which would affect the normal flow of the liquid, thereby achieving the technical effect of reducing the failure rate of the microbubble generating component 120.

[0191] Specifically, the ratio of the first area to the second area can be selected as 8, 10, or 12.

[0192] With the ratio of the first area to the second area being 10, the liquid can increase its flow rate to nearly 10 times in the acceleration section 12622.

[0193] like Figure 9 and Figure 11 As shown, in some embodiments of the present invention, optionally, the intake device 128 includes: a fourth pipe 1282, the first end of the fourth pipe 1282 being connected to the acceleration device 126; and a one-way valve 1284, the one-way valve 1284 being disposed in the fourth pipe 1282, the one-way valve 1284 being unidirectionally open in the direction from the second end of the fourth pipe 1282 to the first end of the fourth pipe 1282.

[0194] In this embodiment, the air intake device 128 includes a fourth pipe 1282 and a one-way valve 1284. The first end of the fourth pipe 1282 is connected to the air inlet 12624 on the third pipe 1262, and the second end of the fourth pipe 1282 is provided with the one-way valve 1284. During operation, gas flows from the fourth pipe 1282 into the air inlet 12624 and is sheared by the accelerated liquid in the third pipe 1262 to form microbubbles.

[0195] The liquid in the third pipe 1262 has a higher flow rate, while the gas in the fourth pipe 1282 has a relatively lower flow rate. Therefore, there is a pressure difference between the third pipe 1262 and the fourth pipe 1282. Under the action of this pressure difference, the gas in the fourth pipe 1282 can automatically flow into the third pipe 1262, thereby realizing automatic gas injection.

[0196] Based on this, the one-way valve 1284 in the fourth pipeline 1282 is unidirectionally open from the second end of the fourth pipeline 1282 to the first end of the fourth pipeline 1282. By setting the one-way valve 1284, leakage of liquid and microbubbles in the third pipeline 1262 from the fourth pipeline 1282 can be prevented, thereby achieving the technical effect of improving the reliability of the microbubble generating component 120.

[0197] like Figure 8 and Figure 9 As shown, in some embodiments of the present invention, the air intake device 128 may optionally include an inflation component 1286, which is connected to the second end of the fourth pipeline 1282.

[0198] In this embodiment, the air intake device 128 further includes an inflation component 1286, which is connected to the second end of the fourth pipe 1282. The inflation component 1286 introduces gas into the third pipe 1262 through the fourth pipe 1282.

[0199] Specifically, the inflation component 1286 includes an air pump, an air cylinder, etc.

[0200] When an air pump is selected as the inflation component 1286, quantitative and timed gas delivery can be achieved, thereby enabling precise control of the microbubble generation process.

[0201] Specifically, the heating device 129 includes a heating film, which is attached to the outer wall of the first pipe 1244, the second pipe 1246 or the third pipe 1262. When energized, the heating film can heat the liquid or microbubbles inside.

[0202] Specifically, the microbubble generation component provided in this application is compared with the foaming equipment in related technologies. The specific experimental data are shown in the table below.

[0205]

[0206] Comparative Example 1 uses a steam foaming machine from the related art. Comparative Example 2 uses a magnetic stirrer from the related art. Example 1 employs the circulating foaming mode of the food processor 100 of this application, that is, the first pipe 1244 connects the pump body 1242 and the cooking chamber 1102, and Example 1 does not heat during the foaming process. Example 2 employs the circulating foaming mode of the food processor 100 of this application, and Example 2 heats during the foaming process. Example 3 employs the single-batch foaming mode of the food processor 100 of this application, that is, the first pipe 1244 connects the pump body 1242 and the liquid storage chamber 1104, and Example 3 does not heat during the foaming process.

[0207] The experimental results show that, compared with Comparative Example 2, Comparative Example 1 has a significantly improved milk foam quality due to heating and other factors. However, the water content of steam whipping also reached 10.5%, which reduced the richness of the milk foam to some extent. Using the food processor 100 provided in this study, not only was no water added, but the stability, fineness, and fluidity of the milk foam were also better than those of the steam whipping and magnetic stirring methods. Therefore, the experimental results prove the feasibility of this embodiment.

[0208] In particular, the quality of milk foam also shows the following pattern: Example 2 > Example 1 > Example 3. Therefore, it is recommended to use the circulating foaming function, and if there is no need for cold / iced drinks, it is also recommended to use the heating function.
