Description

Technical Field

[0001] This application relates to the field of beverage preparation equipment control technology, and in particular to a control method for beverage preparation equipment and beverage preparation equipment. Background Technology

[0002] Most coffee machines on the market currently rely on users manually adjusting the coarseness of the coffee grounds to correct the pressure during brewing. This manual adjustment method is relatively crude, requiring users to have certain experience and skills, and the pressure cannot be dynamically adjusted in real time during the actual brewing process. This limitation often leads to less than ideal coffee extraction, thus affecting the final coffee quality and taste. If the brewing pressure is too low, the coffee may be under-extracted and taste weak; while if the pressure is too high, the coffee may have a bitter taste, affecting the overall flavor. Summary of the Invention

[0003] In view of the above-mentioned technical problems existing in the prior art, this application provides a control method for beverage preparation equipment and beverage preparation equipment.

[0004] This application provides a control method for a beverage preparation device, comprising: acquiring a brewing operation; the brewing operation at least corresponding to a target brewing pressure for brewing powdered ingredients; determining a stored initial brewing pressure and a current first gear; wherein the first gear at least represents the current gear position of the gear adjustment component of the beverage preparation device, the initial brewing pressure is a stored pressure corresponding to the current first gear, the gear adjustment component has multiple gears to adjust the particle size of the powdered ingredients formed by the grinding component of the beverage preparation device at different gears; determining a target adjustment gear corresponding to the gear adjustment component based on the target brewing pressure, the initial brewing pressure, and the current first gear; after the grinding component works at the target adjustment gear to form powdered ingredients, determining the real-time brewing pressure of the brewing component of the beverage preparation device for brewing the powdered ingredients; and controlling the operating parameters of the brewing component based on the real-time brewing pressure and the target brewing pressure. The above method is simple for users to operate and can improve quality stability. In particular, compared with manual pressure adjustment, it reduces the requirements for user operation and ensures that the taste of the prepared beverage is not affected by the user's operating skills.

[0005] In some embodiments, determining the target adjustment level of the corresponding adjustment component based on the target brewing pressure, the initial brewing pressure, and the current first level specifically includes: determining the target adjustment level as a second level when the stored initial brewing pressure is greater than the target brewing pressure; wherein the particle size of the powdered food ground at the second level is greater than that ground at the first level; and determining the target adjustment level as a third level when the stored initial brewing pressure is less than the target brewing pressure; wherein the particle size of the powdered food ground at the third level is less than that ground at the first level. Thus, by comparing the stored initial brewing pressure with the target brewing pressure, the level can be lowered or raised to grind powdered food that meets the particle size requirements, thereby preparing a beverage with the desired taste.

[0006] In some embodiments, the method further includes: real-time acquisition of the rotation angle of the rotating support of the grinding component via a speed detection component of the beverage preparation equipment; wherein the grinding component further includes a blade assembly connected to the rotating support, and the speed adjustment component is used to rotate the rotating support to adjust the blade gap of the blade assembly, thereby adjusting the particle size of the ground powder; based on the target adjustment speed and the acquired rotation angle, the speed adjustment component is controlled to operate, so that the grinding component operates at the target adjustment speed to form powder. Thus, by real-time acquisition of the rotation angle of the rotating support of the grinding component, precise adjustment of the blade gap can be achieved, thereby precisely adjusting the particle size of the powder, effectively improving the ease of operation and consistency of the beverage preparation equipment, and increasing grinding efficiency.

[0007] In some embodiments, after determining the real-time brewing pressure of the brewing component of the beverage preparation device for brewing the powdered ingredients, the method further includes: storing the real-time brewing pressure as an initial brewing pressure, so as to call the real-time brewing pressure to determine the target adjustment level corresponding to the next brewing operation; wherein, the real-time brewing pressure is the pressure corresponding to the determined target adjustment level. Thus, by storing the real-time brewing pressure as the initial brewing pressure, the real-time brewing pressure can be directly called as the initial brewing pressure for calculation in the next brewing operation, so as to accurately determine the corresponding target adjustment level.

[0008] In some embodiments, determining the real-time brewing pressure of the brewing component of the beverage preparation equipment for brewing the powdered ingredients specifically includes: receiving pressure information collected by the pressure detection component of the beverage preparation equipment from a first pipe; wherein the beverage preparation equipment further includes a heating component, the brewing component includes a brewing chamber, the heating component supplies water to the brewing chamber through the first pipe, and the pressure detection component is located in the first pipe; and determining the real-time brewing pressure of the brewing component for brewing the powdered ingredients based on the pressure information. Thus, by collecting pressure information from the first pipe in real time through the pressure detection component, the control component can determine the brewing pressure of the brewing component when brewing the powdered ingredients, thereby effectively monitoring and adjusting pressure changes during the brewing process, ensuring the stability and consistency of beverage preparation.

[0009] In some embodiments, the beverage preparation equipment further includes a temperature detection component and a heating component. The temperature detection component is used to detect the liquid temperature information within the heating component. The method further includes: determining the target brewing temperature for the powdered ingredients corresponding to the brewing operation; and controlling the heating power of the heating component based on the target brewing temperature and the real-time detected liquid temperature information. Thus, the heating power of the heating component can be precisely controlled using the real-time detected liquid temperature information, thereby ensuring that the liquid reaches the target brewing temperature during the brewing process.

[0010] In some embodiments, controlling the operating parameters of the brewing component based on the real-time brewing pressure and the target brewing pressure specifically includes: reducing the operating pressure of the water pump in the brewing component when the real-time brewing pressure is greater than the target brewing pressure; and increasing the operating pressure of the water pump in the brewing component when the real-time brewing pressure is less than the target brewing pressure. Thus, by dynamically adjusting the operating pressure of the water pump in the brewing component based on a comparison of the real-time brewing pressure and the target brewing pressure, pressure stability during the brewing process can be maintained.

[0011] This application also provides a beverage preparation device, including a speed adjustment component, a grinding component, a brewing component, and a control component. The speed adjustment component has multiple speeds to adjust the particle size of the powdered food formed by the grinding component at different speeds. The brewing component is used to brew the powdered food formed by the grinding component. The control component is used to execute the control method of the beverage preparation device described in any of the above embodiments. The above method is simple for users to operate and can improve quality stability. In particular, compared with manual pressure adjustment, it can reduce the requirements for user operation and ensure that the taste of the prepared beverage is not affected by the user's operating skills.

[0012] In some embodiments, the gear adjustment assembly includes a drive member and a first tooth connected to each other, and the grinding assembly includes a rotating bracket and a blade assembly. The drive member is rotatably connected to the rotating bracket via the first tooth, so as to drive the rotating bracket to rotate via the first tooth. The blade assembly includes a fixed blade and a movable blade disposed on the rotating bracket. The rotating bracket is used to rotatably drive the movable blade away from or towards the fixed blade, so as to adjust the particle size of the powdered food by adjusting the blade gap between the fixed blade and the movable blade. In this way, the blade gap between the fixed blade and the movable blade can be precisely adjusted by rotating the bracket, thereby achieving the purpose of precisely adjusting the particle size of the powdered food.

[0013] In some embodiments, the beverage preparation equipment further includes a gear position detection component, which includes a second tooth and an angle detection device connected to each other. The outer wall of the rotating support is formed with an annular tooth, and both the first and second teeth mesh with the annular tooth. The angle detection device is used to detect the angle at which the second tooth rotates with the annular tooth to determine the rotation angle of the rotating support. Thus, the gear position detection component can collect the rotation angle of the rotating support of the grinding assembly in real time, enabling precise adjustment of the blade gap, thereby accurately adjusting the particle size of the powdered ingredients. This effectively improves the ease of operation and consistency of the beverage preparation equipment, as well as increasing grinding efficiency.

[0014] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: This application determines the target adjustment level by calling the initial brewing pressure stored from the last brewing and the current first setting, and combining the two with the target brewing pressure corresponding to the current brewing operation. Then, a two-step pressure control process is performed. The first step of the pressure control process is that the grinding component works at the target adjustment level to grind the ingredients into powder. At this time, the brewing pressure at the adjusted target adjustment level is close to the target brewing pressure. The second step of the pressure control process is to control the working parameters of the brewing component according to the real-time brewing pressure and the target brewing pressure. That is, the working of the brewing component is adjusted in real time through real-time pressure feedback, so that the real-time brewing pressure can be closer to the target brewing pressure, thereby brewing a beverage taste that meets the user's choice. The above method is simple for users to operate and can improve the stability of quality. In particular, compared with the manual pressure adjustment method, it can reduce the requirements for user operation and ensure that the taste of the prepared beverage is not affected by the user's operating skills.

[0023] The above and other aspects, features and advantages of this application will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description.

[0024] Specific embodiments of this application are described thereafter with reference to the accompanying drawings; however, it should be understood that the embodiments are merely examples of this application, which may be implemented in various ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that could obscure the application. Therefore, the specific structural and functional details herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in a variety of substantially any suitable detailed structures.

[0025] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0026] This application provides a control method for a beverage preparation device. The beverage preparation device can be a coffee machine, beverage machine, tea machine, etc., and this application does not specifically limit the beverages prepared by the beverage preparation device. The control method for the beverage preparation device described below can be executed via the control component 11 of the beverage preparation device. For example... Figure 1 As shown, the control method for the beverage preparation equipment includes steps S101 to S105.

[0027] Step S101: Obtain brewing operation; the brewing operation corresponds at least to the target brewing pressure for brewing powdered ingredients.

[0028] The aforementioned beverage preparation equipment may include a control unit, allowing users to operate it precisely and thus enabling the equipment to receive the user's brewing instructions. For example, the control unit may have a display screen, on which the user selects the desired beverage, such as espresso or Americano.

[0029] The brewing parameters described above can be manually entered by the user or flavor parameters selected by the user according to their needs. In addition to the target brewing pressure, the parameters corresponding to the brewing operation may also include the target brewing temperature, target volume, and brewing time.

[0030] Users can update the parameters stored in the beverage preparation equipment for different flavors via mobile devices, such as adding more flavor parameters or adjusting flavor parameters.

[0031] The following explanation uses powdered coffee as an example. The target brewing pressure can vary depending on the flavor of the beverage. For example, the target brewing pressure for espresso is 9 bar, for Americano it's 6 bar, and for long brew it's 7 bar. Step S102: Determine the stored initial brewing pressure and the current first gear; wherein, the first gear at least represents the current gear position of the gear adjustment component 1 of the beverage preparation equipment, the initial brewing pressure is the stored pressure corresponding to the current first gear, and the gear adjustment component 1 has multiple gears to adjust the particle size of the powdered ingredients formed by the grinding component 2 of the beverage preparation equipment at different gears.

[0032] The beverage preparation equipment described above may have a memory 12 electrically connected to the control component 11. The memory 12 may store the initial brewing pressure and the current first setting. The initial brewing pressure and the current first setting can be understood as data stored from the last brewing operation. After each brewing operation, the initial brewing pressure and the current first setting will be updated so that the target adjustment setting can be calculated using the data from the previous brewing operation in the next brewing operation.

[0033] like Figures 2 to 5 As shown, the gear adjustment component 1 has an automatically adjustable gear. The gear adjustment component 1 may include a drive component 101, which can drive the grinding component 2 to rotate and adjust the particle size of the powdered food.

[0034] Understandably, the particle size of the resulting powdered food increases with the increase of the setting. For example, the setting adjustment component 1 can have ten settings, namely setting 1, setting 2, ... setting 10, where setting 10 corresponds to the coarsest particle size and setting 1 corresponds to the finest particle size. The aforementioned first setting can be any of the ten settings; this application does not specifically limit this, as long as it is the setting stored from the last brewing operation.

[0035] Understandably, the grinding component 2 of the beverage preparation equipment will not reset after brewing, but will remain at the setting used in this brewing, so as to facilitate precise adjustment of the setting for the next brewing.

[0036] Step S103: Determine the target adjustment level corresponding to the adjustment component 1 based on the target brewing pressure, the initial brewing pressure and the current first level.

[0037] After determining the target adjustment level, the control level adjustment component 1 is switched to the target adjustment level, so that the grinding component 2 can perform grinding work at the target adjustment level, thereby forming the corresponding powdered food.

[0038] For example, if the target brewing pressure is 10 bar, the initial brewing pressure is 4 bar, and the current first setting is level six, it indicates that the powdered ingredients have a larger particle size, i.e., the powdered ingredients are coarser. Powdered ingredients with larger particle size have less resistance to the brewing liquid and a faster flow rate, so the pressure will be lower (i.e., 4 bar is less than 10 bar). In order to ensure the stability of the taste of the prepared beverage, it can be determined that the powdered ingredients formed by the grinding component 2 should be finer. Thus, it can be determined that the target adjustment level is less than the first setting, such as the target adjustment level being level three.

[0039] Step S104: After the grinding component 2 operates at the target adjustment level to form powdered ingredients, determine the real-time brewing pressure of the brewing component 3 of the beverage preparation equipment for brewing the powdered ingredients.

[0040] The brewing component 3 may include a water pump 32. After the target adjustment level is determined, the water pump 32 operates at the initial working pressure. The initial working pressure of the water pump 32 can be understood as fixed, that is, the water pump 32 operates at the initial working pressure every time brewing is performed.

[0041] Step S105: Control the operating parameters of the brewing component 3 according to the real-time brewing pressure and the target brewing pressure.

[0042] Specifically, when the real-time brewing pressure and the target brewing pressure are inconsistent, the working parameters of the brewing component 3 will be adjusted according to the target brewing pressure, so that the brewing component 3 can brew powdered ingredients at the target brewing pressure corresponding to the brewing operation.

[0043] The beverage preparation equipment described above may also include a flow meter 9 and a water tank 10. The flow meter 9 is located downstream of the outlet of the water tank 10 and is used to detect the flow rate of the water discharged through the water tank 10.

[0044] The first step of pressure control can be achieved by adjusting the gear of the gear adjustment component 1 to the target adjustment gear. The second step of pressure control can be achieved by controlling the working parameters of the brewing component 3 through real-time brewing pressure and target brewing pressure. This two-step pressure control process can produce a beverage taste that meets the user's choice.

[0045] The aforementioned control of the operating parameters of the brewing component 3 can be specifically defined as controlling the operating pressure of the water pump 32 of the brewing component 3. That is, the water pump 32 first operates at the initial operating pressure, at which time the real-time brewing pressure is detected, and then the real-time brewing pressure is compared with the target brewing pressure. Based on the comparison result, the operating parameters of the brewing component 3 can be controlled.

[0046] This application determines the target adjustment level by calling the initial brewing pressure stored from the last brewing and the current first setting, and combining these two with the target brewing pressure corresponding to the current brewing operation. Then, a two-step pressure control process is performed. The first step involves the grinding component 2 grinding the ingredients into powder at the target adjustment level, at which point the brewing pressure at the adjusted target adjustment level is close to the target brewing pressure. The second step involves controlling the working parameters of the brewing component 3 based on the real-time brewing pressure and the target brewing pressure. That is, the brewing component 3 is adjusted in real-time through real-time pressure feedback, making the real-time brewing pressure even closer to the target brewing pressure, thereby brewing a beverage with a taste that matches the user's choice. This method is simple for users to operate and improves quality stability. In particular, compared to manual pressure adjustment, it reduces the requirements for user operation and ensures that the taste of the prepared beverage is not affected by the user's operating skills.

[0047] In some embodiments, such as Figure 6 As shown, step S103, which involves determining the target adjustment level of the corresponding adjustment component 1 based on the target brewing pressure, the initial brewing pressure, and the current first level, specifically includes steps S201 to S202.

[0048] Step S201: When the stored initial brewing pressure is greater than the target brewing pressure, the target adjustment level is determined to be the second level; wherein, the particle size of the powdered food formed by grinding under the second level is greater than the particle size of the powdered food formed by grinding under the first level.

[0049] Step S202: If the stored initial brewing pressure is less than the target brewing pressure, determine the target adjustment level as the third level; wherein, the particle size of the powdered food formed by grinding at the third level is less than the particle size of the powdered food formed by grinding at the first level.

[0050] In this way, by comparing the initial brewing pressure and the target brewing pressure, the brewing pressure can be adjusted to lower or higher to grind the ingredients into powder that meets the particle size requirements, thereby preparing a beverage that meets the desired taste.

[0051] When the initial brewing pressure corresponding to the last brewing session updated in memory 12 is greater than the target brewing pressure, it indicates that the pressure of the last brewing session was relatively high. That is, the finer the coffee powder particles, the greater the resistance, and therefore the higher the brewing pressure, indicating that the coffee grind setting needs to be adjusted to coarser. After comparison and calculation, control component 11 will calculate that the coffee grind setting needs to be coarser, and drive component 101 needs to reverse. Specifically, control component 11 determines the target adjustment setting based on the target brewing pressure, the initial brewing pressure, and the current first setting. For example, the greater the difference between the initial brewing pressure stored in memory 12 and the target brewing pressure, the greater the adjustment degree of setting adjustment component 1 (as shown below, the greater the angle of movement of the first tooth 102 controlled by drive component 101).

[0052] When the initial brewing pressure corresponding to the last brewing session updated in memory 12 is less than the target brewing pressure, it indicates that the pressure of the last brewing session was relatively low. That is, the coarser the coffee powder particles, the lower the resistance, and the lower the brewing pressure, indicating that the coffee powder setting needs to be adjusted to a finer level. After comparison and calculation, control component 11 will calculate that the coffee grind setting needs to be adjusted to a finer level, and drive component 101 needs to rotate forward. Specifically, control component 11 determines the target adjustment level based on the target brewing pressure, the initial brewing pressure, and the current first level. For example, the greater the difference between the initial brewing pressure stored in memory 12 and the target brewing pressure, the greater the adjustment degree of the level adjustment component 1 (as shown below, the greater the angle of movement of the first tooth 102 controlled by drive component 101).

[0053] In some embodiments, such as Figure 7 As shown, the method further includes steps S301 to S302.

[0054] Step S301: The rotation angle of the rotating support 21 of the grinding component 2 is collected in real time by the gear detection component 4 of the beverage preparation equipment; wherein, the grinding component 2 also includes a blade assembly 22 connected to the rotating support 21, and the gear adjustment component 1 is used to drive the rotating support 21 to rotate and adjust the blade gap of the blade assembly 22, so as to adjust the particle size of the powdered food formed by grinding.

[0055] Step S302: Based on the target adjustment level and the collected rotation angle, control the adjustment component 1 to work, so that the grinding component 2 works at the target adjustment level to form powdered food.

[0056] In this way, the rotation angle of the rotating bracket 21 of the grinding component 2 can be collected in real time to achieve precise adjustment of the blade gap, thereby precisely adjusting the particle size of the powdered ingredients, effectively improving the ease of operation and consistency of the beverage preparation equipment, as well as increasing the grinding efficiency.

[0057] The aforementioned gear detection component 4 may include at least an angle detection device 42, which can accurately detect the rotation angle of the rotating bracket 21 of the grinding component 2. It is understood that the rotation angle of the rotating bracket 21 is related to the blade clearance of the blade assembly 22, that is, it is related to the particle size of the powdered food formed by grinding. By collecting the rotation angle of the rotating bracket 21 in real time, the blade clearance of the blade assembly 22 can be calculated in real time to determine whether the current gear is the target adjustment gear. After the current gear is adjusted to the target adjustment gear, the control component 11 can control the gear adjustment component 1 to stop adjusting, so that the grinding component 2 can work at the target adjustment gear to form powdered food with the corresponding particle size.

[0058] like Figures 2 to 5 As shown, the gear detection component 4 may include a second tooth 41 connected to the angle detection device 42. The second tooth 41 meshes with the ring tooth 25 of the rotating bracket 21, so that the second tooth 41 and the rotating bracket 21 can rotate synchronously. The angle detection device 42 may be a potentiometer. The rotation of the second tooth 41 can change the resistance value of the potentiometer, thereby generating information related to the rotation angle of the rotating bracket 21.

[0059] The aforementioned gear adjustment component 1 may further include a first tooth 102 connected to the drive member 101. The drive member 101 is rotatably connected to the rotating bracket 21 via the first tooth 102, so as to drive the rotating bracket 21 to rotate via the first tooth 102. The blade assembly 22 includes a fixed blade 23 and a movable blade 24 disposed on the rotating bracket 21. The rotating bracket 21 is used to rotatably drive the movable blade 24 away from or towards the fixed blade 23, so as to adjust the particle size of the powdered food by adjusting the blade gap between the fixed blade 23 and the movable blade 24. Specifically, the rotating bracket 21 can rotatably drive the movable blade 24 to perform lifting and lowering movements. For example, if the rotating bracket 21 and the movable blade 24 are threadedly connected, the movable blade 24 can perform lifting and lowering movements relative to the fixed blade 23 after being limited, but will not rotate with the rotating bracket 21 when limited.

[0060] The operation of the gear adjustment component 1 in step 302 above can be understood as controlling the rotation of the drive component 101, thereby controlling the rotation angle between the first tooth 102 and the rotating bracket 21.

[0061] In some embodiments, after determining the real-time brewing pressure of the brewing component 3 of the beverage preparation device for brewing the powdered ingredients in step S104, the method further includes: The real-time brewing pressure is stored as the initial brewing pressure, so that it can be called during the next brewing operation to determine the target adjustment level corresponding to the next brewing operation; wherein, the real-time brewing pressure is the pressure corresponding to the determined target adjustment level.

[0062] In this way, by storing the real-time brewing pressure as the initial brewing pressure, the real-time brewing pressure can be directly called as the initial brewing pressure for calculation in the next brewing operation, so as to accurately determine the corresponding target adjustment level. This ensures a consistent pressure standard in each brewing process, thereby improving the stability and consistency of the brewing effect, and thus optimizing the taste and quality of the beverage.

[0063] The aforementioned real-time brewing pressure can be understood as the pressure corresponding to the currently calculated target adjustment level. At this time, the water pump 32 operates at its initial working pressure and has not been adjusted. When it is determined that the real-time brewing pressure and the target brewing pressure are different, the working pressure of the water pump 32 of the brewing component 3 is adjusted according to the target brewing pressure. Since the grinding level has already been adjusted before, the working pressure of the water pump 32 only needs to be finely adjusted.

[0064] In some embodiments, step S104, determining the real-time brewing pressure of the brewing component 3 of the beverage preparation equipment for brewing the powdered ingredients, specifically includes: The beverage preparation equipment receives pressure information collected by the pressure detection component 5 from the first pipe 7; the beverage preparation equipment also includes a heating component 6, and the brewing component 3 includes a brewing chamber 31. The heating component 6 supplies water to the brewing chamber 31 through the first pipe 7, and the pressure detection component 5 is located on the first pipe 7; the control component 11 determines the real-time brewing pressure of the brewing component 3 for brewing the powdered ingredients based on the pressure information. The brewing chamber 31 contains the powdered ingredients formed after grinding by the grinding component 2.

[0065] Thus, by collecting pressure information on the first pipe 7 in real time through the pressure detection component 5, the control component 11 can determine the brewing pressure of the brewing component 3 when brewing powdered ingredients, so as to effectively monitor and adjust the pressure changes during the brewing process, thereby ensuring the stability and consistency of beverage preparation. Furthermore, the pressure detection component 5 is set on the first pipe 7, which can realize the accurate detection of the brewing pressure of powdered ingredients.

[0066] like Figure 8 As shown, the pressure detection component 5 can be understood as directly collecting the liquid pressure in the first pipe 7. The control component 11 receives the detection result of the pressure detection component 5 and can calculate the real-time brewing pressure of the brewing component 3 for brewing powdered food. Since the pressure detection component 5 is set close to the brewing chamber 31, that is, the pressure value detected by the pressure detection component 5 is closer to the brewing chamber 31, the accuracy of the calculated real-time brewing pressure of the powdered food can be improved.

[0067] like Figure 8 As shown, the water pump 32 can be connected to the heating component 6 through the second pipe, that is, the water pump 32 is located upstream of the heating component 6, and the heating component 6 is located upstream of the brewing chamber 31, so that the brewing liquid from the water pump 32 is heated by the heating component 6 and then discharged into the brewing chamber 31 to brew powdered food.

[0068] In some embodiments, such as Figure 9 As shown, the beverage preparation equipment further includes a temperature detection component 8 and a heating component 6. The temperature detection component 8 is used to detect the liquid temperature information in the heating component 6. The method further includes steps S401 to S402.

[0069] Step S401: Determine the target brewing temperature for the powdered food corresponding to the brewing operation.

[0070] Step S402: Control the heating power of the heating component 6 according to the target brewing temperature and the real-time detected liquid temperature information.

[0071] In this way, the heating power of the heating component 6 can be precisely controlled by using real-time detected liquid temperature information, thereby ensuring that the liquid reaches the target brewing temperature during the brewing process. This not only improves the flavor and taste of the beverage, but also improves the consistency and efficiency of brewing, ensuring that each brewing meets the user's drinking needs.

[0072] The temperature detection component 8 can be directly installed on the heating component 6 to detect and provide real-time feedback on the temperature of the liquid heated by the heating component 6.

[0073] Specifically, if the real-time detected liquid temperature is higher than the target brewing temperature, the heating power of the heating component 6 will be reduced; if the real-time detected liquid temperature is lower than the target brewing temperature, the heating power of the heating component 6 will be increased.

[0074] In some embodiments, controlling the operating parameters of the brewing component 3 based on the real-time brewing pressure and the target brewing pressure specifically includes: If the real-time brewing pressure is greater than the target brewing pressure, the working pressure of the water pump 32 of the brewing component 3 will be reduced. If the real-time brewing pressure is less than the target brewing pressure, the working pressure of the water pump 32 of the brewing component 3 will be increased.

[0075] Thus, by dynamically adjusting the working pressure of the water pump 32 in the brewing component 3 based on the comparison between the real-time brewing pressure and the target brewing pressure, pressure stability can be maintained during the brewing process. When the real-time brewing pressure is too high, appropriately reducing the pressure of the water pump 32 helps prevent over-extraction and ensures that the taste of the beverage is not affected; while when the real-time brewing pressure is too low, increasing the pressure of the water pump 32 can enhance the extraction effect and ensure that the ingredients fully release their flavor. This intelligent feedback mechanism significantly improves the consistency and quality of brewing, meeting consumers' demand for high-quality beverages.

[0076] This application also provides a beverage preparation device. For example... Figures 2 to 5 , Figure 8 and Figure 10 As shown, the beverage preparation equipment includes a speed adjustment component 1, a grinding component 2, a brewing component 3, and a control component 11. The speed adjustment component 1 has multiple speeds to adjust the particle size of the powdered food formed by the grinding component 2 at different speeds. The brewing component 3 is used to brew the powdered food formed by the grinding component 2. The control component 11 is used to execute the control method of the beverage preparation equipment described in any of the above embodiments.

[0077] The aforementioned beverage preparation equipment may include a control unit, allowing users to operate it precisely and thus enabling the equipment to receive the user's brewing instructions. For example, the control unit may have a display screen, on which the user selects the desired beverage, such as espresso or Americano.

[0078] The brewing parameters described above can be manually entered by the user or selected by the user based on their needs. In addition to the target brewing pressure, the parameters corresponding to the brewing operation may also include the target brewing temperature, target volume, and brewing time.

[0079] Users can update the parameters stored in the beverage preparation equipment for different flavors via mobile devices, such as adding more flavor parameters or adjusting flavor parameters.

[0080] like Figure 10 As shown, the beverage preparation equipment described above may have a power supply module 13, which provides power to each component of the beverage preparation equipment that requires electrical energy.

[0081] The beverage preparation equipment described above may have a memory 12 electrically connected to the control component 11. The memory 12 may store the initial brewing pressure and the current first setting. The initial brewing pressure and the current first setting can be understood as data stored from the last brewing operation. After each brewing operation, the initial brewing pressure and the current first setting will be updated so that the target adjustment setting can be calculated using the data from the previous brewing operation in the next brewing operation.

[0082] like Figures 2 to 5 As shown, the gear adjustment component 1 has an automatically adjustable gear. The gear adjustment component 1 may include a drive component 101, which can drive the grinding component 2 to rotate and adjust the particle size of the powdered food.

[0083] Understandably, the particle size of the resulting powdered food increases with the increase of the setting. For example, the setting adjustment component 1 can have ten settings, namely setting 1, setting 2, ... setting 10, where setting 10 corresponds to the coarsest particle size and setting 1 corresponds to the finest particle size. The aforementioned first setting can be any of the ten settings; this application does not specifically limit this, as long as it is the setting stored from the last brewing operation.

[0084] Understandably, the grinding component 2 of the beverage preparation equipment will not reset after brewing, but will remain at the setting used in this brewing, so as to facilitate precise adjustment of the setting for the next brewing.

[0085] The brewing component 3 may include a water pump 32. After the target adjustment level is determined, the water pump 32 operates at the initial working pressure. The initial working pressure of the water pump 32 can be understood as fixed, that is, the water pump 32 operates at the initial working pressure every time brewing is performed.

[0086] Specifically, when the real-time brewing pressure and the target brewing pressure are inconsistent, the working parameters of the brewing component 3 will be adjusted according to the target brewing pressure, so that the brewing component 3 can brew powdered ingredients at the target brewing pressure corresponding to the brewing operation.

[0087] The beverage preparation equipment described above may also include a flow meter 9 and a water tank 10. The flow meter 9 is located downstream of the outlet of the water tank 10 and is used to detect the flow rate of the water discharged through the water tank 10.

[0088] The first step of pressure control can be achieved by adjusting the gear of the gear adjustment component 1 to the target adjustment gear, and the second step of pressure control can be achieved by controlling the working parameters of the brewing component 3 by real-time brewing pressure and target brewing pressure. This two-step pressure control process can achieve the brewing of a beverage taste that meets the user's choice.

[0089] The aforementioned control of the operating parameters of the brewing component 3 can be specifically defined as controlling the operating pressure of the water pump 32 of the brewing component 3. That is, the water pump 32 first operates at the initial operating pressure, at which time the real-time brewing pressure is detected, and then the real-time brewing pressure is compared with the target brewing pressure. Based on the comparison result, the operating parameters of the brewing component 3 can be controlled.

[0090] This application determines the target adjustment level by calling the initial brewing pressure stored from the last brewing and the current first setting, and combining these two with the target brewing pressure corresponding to the current brewing operation. Then, a two-step pressure control process is performed. The first step involves the grinding component 2 grinding the ingredients into powder at the target adjustment level, at which point the brewing pressure at the adjusted target adjustment level is close to the target brewing pressure. The second step involves controlling the working parameters of the brewing component 3 based on the real-time brewing pressure and the target brewing pressure. That is, the brewing component 3 is adjusted in real-time through real-time pressure feedback, making the real-time brewing pressure even closer to the target brewing pressure, thereby brewing a beverage with a taste that matches the user's choice. This method is simple for users to operate and improves quality stability. In particular, compared to manual pressure adjustment, it reduces the requirements for user operation and ensures that the taste of the prepared beverage is not affected by the user's operating skills.

[0091] In some embodiments, such as Figures 2 to 5 As shown, the gear adjustment component 1 includes a drive member 101 and a first tooth 102 connected to each other. The grinding component 2 includes a rotating bracket 21 and a blade assembly 22. The drive member 101 is rotatably connected to the rotating bracket 21 through the first tooth 102, so as to drive the rotating bracket 21 to rotate through the first tooth 102. The blade assembly 22 includes a fixed blade 23 and a movable blade 24 disposed on the rotating bracket 21. The rotating bracket 21 is used to rotatably drive the movable blade 24 away from or towards the fixed blade 23, so as to adjust the particle size of the powdered food by adjusting the blade gap between the fixed blade 23 and the movable blade 24.

[0092] In this way, the gap between the fixed blade 23 and the movable blade 24 can be precisely adjusted by rotating the bracket 21, thereby achieving the purpose of precisely adjusting the particle size of the powdered food.

[0093] The aforementioned gear adjustment component 1 may further include a first tooth 102 connected to the drive member 101. The drive member 101 is rotatably connected to the rotating bracket 21 via the first tooth 102, so as to drive the rotating bracket 21 to rotate via the first tooth 102. The blade assembly 22 includes a fixed blade 23 and a movable blade 24 disposed on the rotating bracket 21. The rotating bracket 21 is used to rotatably drive the movable blade 24 away from or towards the fixed blade 23, so as to adjust the particle size of the powdered food by adjusting the blade gap between the fixed blade 23 and the movable blade 24. Specifically, the rotating bracket 21 can rotatably drive the movable blade 24 to perform lifting and lowering movements. For example, if the rotating bracket 21 and the movable blade 24 are threadedly connected, the movable blade 24 can perform lifting and lowering movements relative to the fixed blade 23 after being limited, but will not rotate with the rotating bracket 21 when limited.

[0094] In some embodiments, such as Figures 2 to 5 As shown, the beverage preparation equipment also includes a gear detection component 4, which includes a second tooth 41 and an angle detection device 42 connected to each other. The outer wall of the rotating bracket 21 is formed with an annular tooth 25. The first tooth 102 and the second tooth 41 both mesh with the annular tooth 25. The angle detection device 42 is used to detect the angle of the second tooth 41 as it rotates with the annular tooth 25, so as to determine the rotation angle of the rotating bracket 21.

[0095] In this way, the rotation angle of the rotating bracket 21 of the grinding component 2 can be collected in real time through the gear detection component 4, so as to achieve precise adjustment of the blade gap, thereby precisely adjusting the particle size of the powdered ingredients, effectively improving the ease of operation and consistency of the beverage preparation equipment, as well as improving the grinding efficiency.

[0096] The aforementioned angle detection device 42 can accurately detect the rotation angle of the rotating bracket 21 of the grinding component 2. It can be understood that the rotation angle of the rotating bracket 21 is related to the blade clearance of the blade assembly 22, that is, it is related to the particle size of the powdered food formed by grinding. By collecting the rotation angle of the rotating bracket 21 in real time, the blade clearance of the blade assembly 22 can be calculated in real time to determine whether the current gear is the target adjustment gear. Until the current gear is adjusted to the target adjustment gear, the control component 11 can control the gear adjustment component 1 to stop adjusting, so that the grinding component 2 can work at the target adjustment gear to form powdered food with the corresponding particle size.

[0097] like Figures 2 to 5 As shown, the second tooth 41 meshes with the ring tooth 25 of the rotating bracket 21, so that the second tooth 41 and the rotating bracket 21 can rotate synchronously. The angle detection device 42 can be a potentiometer. The rotation of the second tooth 41 can change the resistance value of the potentiometer, thereby generating information related to the rotation angle of the rotating bracket 21.

[0098] In some embodiments, such as Figure 8 As shown, the beverage preparation equipment further includes a heating component 6, and the brewing component 3 includes a brewing chamber 31. The heating component 6 supplies water to the brewing chamber 31 through a first pipe 7. The pressure detection component 5 is installed on the first pipe 7, and the control component 11 is used to acquire the pressure information collected by the pressure detection component 5 on the first pipe 7, and determine the real-time brewing pressure of the brewing component 3 for brewing the powdered ingredients based on the pressure information. The brewing chamber 31 contains the powdered ingredients formed after being ground by the grinding component 2.

[0099] Thus, by collecting pressure information on the first pipe 7 in real time through the pressure detection component 5, the control component 11 can determine the brewing pressure of the brewing component 3 when brewing powdered ingredients, so as to effectively monitor and adjust the pressure changes during the brewing process, thereby ensuring the stability and consistency of beverage preparation. Furthermore, the pressure detection component 5 is set on the first pipe 7, which can realize the accurate detection of the brewing pressure of powdered ingredients.

[0100] like Figure 8 As shown, the pressure detection component 5 can be understood as directly collecting the liquid pressure in the first pipe 7. The control component 11 receives the detection result of the pressure detection component 5 and can calculate the real-time brewing pressure of the brewing component 3 for brewing powdered food. Since the pressure detection component 5 is set close to the brewing chamber 31, that is, the pressure value detected by the pressure detection component 5 is closer to the brewing chamber 31, the accuracy of the calculated real-time brewing pressure of the powdered food can be improved.

[0101] like Figure 8 As shown, the water pump 32 can be connected to the heating component 6 through the second pipe, that is, the water pump 32 is located upstream of the heating component 6, and the heating component 6 is located upstream of the brewing chamber 31, so that the brewing liquid from the water pump 32 is heated by the heating component 6 and then discharged into the brewing chamber 31 to brew powdered food.

[0102] In some embodiments, such as Figure 9 As shown, the beverage preparation equipment further includes a temperature detection component 8 and a heating component 6. The temperature detection component 8 is used to detect the liquid temperature information within the heating component 6. The control component 11 is also used to determine the target brewing temperature for the powdered ingredients corresponding to the brewing operation; and to control the heating power of the heating component 6 based on the target brewing temperature and the real-time detected liquid temperature information.

[0103] In this way, the heating power of the heating component 6 can be precisely controlled by using real-time detected liquid temperature information, thereby ensuring that the liquid reaches the target brewing temperature during the brewing process. This not only improves the flavor and taste of the beverage, but also improves the consistency and efficiency of brewing, ensuring that each brewing meets the user's drinking needs.

[0104] The temperature detection component 8 can be directly installed on the heating component 6 to detect and provide real-time feedback on the temperature of the liquid heated by the heating component 6.

[0105] Specifically, if the real-time detected liquid temperature is higher than the target brewing temperature, the heating power of the heating component 6 will be reduced; if the real-time detected liquid temperature is lower than the target brewing temperature, the heating power of the heating component 6 will be increased.

[0106] The working process of the beverage preparation equipment is explained below. For example... Figure 11 As shown, firstly, the brewing operation is acquired, and the stored initial brewing pressure and current first gear are determined based on the brewing operation. Then, the target adjustment gear corresponding to the gear adjustment component 1 is determined based on the target brewing pressure, initial brewing pressure, and current first gear. It is then determined whether the target adjustment gear is greater than the first gear; if so, the drive component 101 reverses, and the gear is increased; if not, the drive component 101 rotates forward, and the gear is decreased. Next, it is determined whether the real-time collected rotation angle is greater than the calculated angle of the corresponding target adjustment gear (this calculated angle is the angle required for the rotating bracket 21 to rotate to the target adjustment gear); if so, the gear adjustment is complete; otherwise, adjustment continues. Once the gear is adjusted to the target adjustment gear, the gear adjustment is complete. Then, it is determined whether the real-time brewing pressure is greater than the target brewing pressure; if so, the working pressure of the water pump 32 is decreased; if not, the working pressure of the water pump 32 is increased. Finally, it is determined whether the real-time detected temperature is greater than the target brewing temperature; if so, the heating power of the heating component 6 is decreased; if not, the heating power of the heating component 6 is increased. Then it determines whether the amount of coffee equals the target amount; if so, it indicates that the extraction is complete; otherwise, water pump 32 continues to supply liquid.
