During use, the powdered ingredients and water are added to the mixing chamber for mixing, and then the mixed beverage is poured from the mixing chamber into a bottle or cup. This not only results in a longer preparation time, but also requires cleaning the mixing chamber after each use, causing inconvenience for the user. Summary of the Invention

[0003] One objective of this invention is to provide a new technical solution for a mixing method.

[0004] A first aspect of the present invention provides a method for preparing a beverage. The method includes: Obtain the target liquid volume and target powder volume for reconstitution; The liquid supply duration is determined based on the target liquid volume and the liquid supply rate. The target powder supply time is determined based on the liquid supply time and the preset delay time, wherein the target powder supply time is less than the liquid supply time; The target powder supply rate is determined based on the target powder quantity and the target powder supply duration. The mixing process is completed based on the liquid supply rate, the liquid supply duration, the powder supply duration, and the target powder supply rate.

[0009] Optionally, the control signal is a rotational speed signal.

[0010] Optionally, the mixing method further includes: Obtain the powder weight and powder dispensing time; The initial powder supply rate is determined based on the powder output weight and powder output time.

[0011] A second aspect of the present invention provides a brewing and mixing apparatus. This apparatus operates the brewing and mixing method described in this invention.

[0012] Optionally, the device includes a base, a powder supply mechanism, a liquid supply mechanism, and a discharge device. The discharge device has a mixing space below it for placing a container. The discharge device includes a main body, which has a first outlet and a plurality of second outlets.

By setting the delay duration, it ensures that liquid supply starts first and / or stops later, and powder supply starts later and / or stops first.

Detailed Implementation

[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0030] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0032] The mixing method according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] The first embodiment of the present invention provides a brewing method. The brewing method includes: S1. Obtain the target liquid volume and target powder volume for reconstitution; S2. Determine the liquid supply duration based on the target liquid volume and the liquid supply rate; S3. Determine the target powder supply time based on the liquid supply time and the preset delay time, wherein the target powder supply time is less than the liquid supply time; S4. Determine the target powder supply rate based on the target powder quantity and the target powder supply duration; S5. The mixing process has been completed based on the liquid supply rate, the liquid supply duration, the powder supply duration, and the target powder supply rate.

[0034] This preparation method is used to prepare milk powder, coffee, protein powder, oatmeal powder, etc. The liquid supplied by the method can be, for example, water or milk. Before preparation, the user inputs a preparation command into the device. Upon receiving the command, the device completes the preparation of the beverage. Specifically, the user's input command can be a "start preparation" command, and the device will complete the preparation upon receiving this command.

[0035] In step S1, the target liquid volume and target powder volume are obtained based on the information input by the user. For example, the target liquid volume, target powder volume, total beverage volume, and concentration can be obtained through operation of the touch panel of the mixing device, Bluetooth input via a mobile APP, or voice input; or the target liquid volume and target powder volume can be obtained based on information stored in the mixing device.

[0036] In step S2, the supply duration is determined based on the target liquid volume and supply rate. The user can input the target liquid volume and target powder volume through the input interface. Alternatively, the target liquid volume and target powder volume can be values ​​calculated based on the user's desired final total liquid volume and concentration of the beverage.

[0037] The liquid supply rate is, for example, the volume of liquid output by the liquid supply mechanism of the mixing equipment per unit time. The liquid supply rate can be a fixed value or set to multiple levels. The liquid supply duration is, for example, the time during which the liquid supply mechanism continuously outputs liquid; optionally, the liquid supply duration = target liquid volume / liquid supply rate.

[0038] In step S3, the target powder supply duration is determined based on the liquid supply duration and the delay duration. The liquid supply duration is combined with the preset delay duration to match the powder supply sequence, ensuring that the liquid supply process completely covers the powder supply process.

[0039] The preset delay time is, for example, the time interval between the liquid supply and powder supply actions. Setting a preset delay time ensures that liquid supply starts first and / or stops last, and powder supply starts last and / or stops first. For example, if the liquid supply time is 30 seconds, setting a preset delay time of 1 second will ensure that powder supply starts 1 second after liquid supply and / or stops 1 second before liquid supply ends. It should be noted that the preset delay time is not fixed and can be adjusted according to the characteristics of the powder. For example, protein powder with poor flowability requires a longer preset delay time to avoid powder residue; coffee powder with good flowability can have a shorter preset delay time to improve brewing efficiency.

[0040] The target powder supply time is, for example, the continuous output time of the powder supply mechanism. To ensure that the liquid supply process completely covers the powder supply process, the powder supply needs to be completed during the liquid supply process; therefore, the target powder supply time is shorter than the liquid supply time. For example, if the liquid supply time is set to 30 seconds and the preset delay time is 1 second, then the target powder supply time is 28 seconds (delay after the start of liquid supply and after the end of powder supply) or 29 seconds (delay only after the start of liquid supply or after the end of powder supply). The 28 seconds or 29 seconds of the powder supply process is completely within the 30 seconds of the liquid supply process. The setting of the target powder supply time must take into account both the uniformity of powder-liquid mixing and the flowability of the powder. If the target powder supply time is too short, the powder may not be completely output; if the target powder supply time is too long, there may be a situation where there is no liquid to receive after the powder supply is completed.

[0041] In step S4, the target powder supply rate is determined based on the target powder quantity and the target powder supply duration determined in step S2. The target powder quantity is, for example, the weight of powder the user expects to add during preparation, which matches the target liquid volume to form a fixed powder-liquid ratio. This target powder quantity can be determined based on the user inputting it through the user interface, or based on the user's desired final total liquid volume and concentration of the beverage. The target powder supply rate is, for example, the weight of powder output by the feeding mechanism per unit time during actual preparation. For example, target powder supply rate = target powder quantity ÷ target powder supply duration.

[0042] In step S5, the mixing process is completed according to the liquid supply rate, liquid supply duration, target powder supply duration, and target powder supply rate determined in the above steps.

[0043] In one specific embodiment, a user prepares milk using a milk preparation device. The user inputs a target liquid volume of 300ml and a target powder volume of 30g through the operation interface. The container is placed below the powder dispensing mechanism and the liquid dispensing mechanism. Based on the liquid dispensing rate determined by the preparation method (10ml / s), the liquid dispensing time is calculated to be 30s; the target powder dispensing speed is 1.07g / s, and the target powder dispensing time is 28s. During preparation, firstly, the liquid dispensing mechanism starts dispensing liquid at a rate of 10ml / s; after a 1-second delay, the powder dispensing mechanism starts dispensing powder at a target powder dispensing rate of 1.07g / s. At this time, the liquid and powder mix together during the descent and enter the container; powder dispensing stops after 28s; liquid dispensing stops after 30s.

[0044] The brewing method of this invention determines the liquid supply duration based on the target liquid volume and supply rate, determines the target powder supply duration based on the liquid supply duration and a preset delay duration, and determines the target powder supply rate based on the target powder volume and the target powder supply duration. By setting a preset delay duration, it ensures that liquid supply starts first and / or stops later, and powder supply starts later and / or stops first. The liquid supply duration combined with the preset delay duration matches the powder supply sequence, thereby ensuring that the liquid supply process completely covers the powder supply process. This allows the powder and liquid to mix during the descent to form the beverage, eliminating the need to mix the powder and liquid in a mixing chamber, thus saving mixing time. In this way, the brewing equipment does not need a mixing chamber; the brewed beverage can be directly placed into the container.

[0045] In some embodiments of the present invention, the process of preparing the powder according to the liquid supply rate, the liquid supply duration, the powder supply duration, and the target powder supply rate includes: Water is continuously supplied at the stated supply rate for the stated supply duration; Powder is continuously dispensed at the target powder supply rate for the specified powder supply duration.

[0046] In this embodiment, the liquid supply time refers to the time during which water is continuously dispensed at the specified supply rate to reach a set amount. The powder supply time refers to the time during which powder is continuously dispensed at the target powder supply rate to reach a set weight. Continuous water and powder dispensing improves the uniformity of water and milk powder mixing, resulting in a finer milk mixture.

[0047] In some embodiments of the present invention, the target powder supply time is the difference between the liquid supply time and the preset delay time.

[0048] This invention simplifies the control logic by establishing a quantitative formula to correlate the target powder supply time with the liquid supply time and the preset delay time. As mentioned earlier, the liquid supply time is 30 seconds and the preset delay time is 1 second. The target powder supply time is either 28 seconds (in which case, there is a delay after the start of liquid supply and after the end of powder supply, the target powder supply time is 30 seconds - 1 second - 1 second = 28 seconds) or 29 seconds (in which case, there is a delay only after the start of liquid supply or after the end of powder supply, the target powder supply time is 30 seconds - 1 second = 29 seconds). The 28 seconds or 29 seconds of the powder supply process is completely within the 30 seconds of the liquid supply process, thus ensuring that the liquid supply process completely covers the powder supply process.

[0049] In some embodiments of the present invention, the preset delay duration includes a pre-set preset delay duration and / or a post-set preset delay duration, wherein the pre-set preset delay duration includes the time interval from the start of liquid supply to the start of powder supply, and the post-set preset delay duration includes the time interval from the stop of powder supply to the stop of liquid supply.

[0050] In this embodiment, the timing of liquid and powder supply is controlled by setting a pre-set delay duration and / or a post-set delay duration. The pre-set delay duration is the preset delay time between the start of liquid supply by the liquid supply mechanism and the start of powder supply by the powder supply mechanism. This pre-set delay duration ensures that the powder mixes with the falling liquid during powder supply, thus preventing powder from scattering during its descent. Furthermore, the pre-set delay duration ensures that the container already contains some liquid before the powder falls into it, effectively absorbing the powder and accelerating its dissolution, preventing clumping when the powder falls directly into the dry container. Optionally, the pre-set delay duration is 0.3s-3s. It should be noted that when preparing an empty container, a larger pre-set delay duration is needed; when the container already contains some liquid, a smaller pre-set delay duration can be used. Of course, the value of the preset delay duration is not limited to the above factors and embodiments, and those skilled in the art can set it according to the physical properties of the powder.

[0051] The preset delay time is the time between when the powder supply mechanism stops supplying powder and when the liquid supply mechanism stops supplying liquid. This preset delay ensures that after the powder supply mechanism stops supplying powder, the liquid supply mechanism continues to supply liquid for a period of time. This allows the subsequent liquid to flush the powder outlet of the powder supply mechanism, reducing powder residue. Furthermore, the subsequent liquid flow can further impact the powder on the liquid surface, accelerating its dissolution, especially if the powder falling into the container has not yet completely dissolved. Optionally, the preset delay time can be 0.3s-3s. It should be noted that when the powder dissolution rate is low, a larger preset delay time is needed; when the powder dissolution rate is high, a smaller preset delay time can be used. Of course, the value of the preset delay time is not limited to the above factors and embodiments; those skilled in the art can set it according to the physical properties of the powder.

[0052] In this embodiment, the preset delay duration may include only the pre-set preset delay duration or the post-set preset delay duration; alternatively, the preset delay duration may include both the pre-set preset delay duration and the post-set preset delay duration. By setting the pre-set preset delay duration and / or the post-set preset delay duration, the preparation quality of the beverage can be significantly improved.

[0053] In some embodiments of the present invention, the step of determining the target powder supply rate based on the target powder quantity and the target powder supply duration includes: The initial powder supply duration is determined based on the target powder quantity and the initial powder supply rate. A control signal is generated based on the ratio of the initial powder supply time to the target powder supply time; The initial powder supply rate is calibrated to the target powder supply rate based on the control signal.

[0054] In this embodiment, the initial powder supply rate is, for example, the reference powder supply rate of the powder supply mechanism under standard operating conditions (e.g., rated voltage, rated speed), or the historical powder supply rate of the powder supply mechanism during its last operation. The initial powder supply duration is determined based on the ratio of the target powder quantity to the initial powder supply rate; for example, the initial powder supply duration is t0. After determining the initial powder supply duration, a control signal is generated based on the ratio of the initial powder supply duration to the target powder supply duration; for example, the target powder supply duration is t1. The ratio is n, i.e., n = t0 / t1. A control signal is generated based on this ratio n. Next, the initial powder supply rate is adjusted to the target powder supply rate according to the control signal.

[0055] In this embodiment, determining the initial powder supply time and the target powder supply time is relatively easy and accurate. The control signal is generated by using their ratio, simplifying the generation of the control signal. In some embodiments of the present invention, the control signal includes a rotational speed signal.

[0056] For example, when the feeding mechanism adopts a spiral feeding method, the powder feeding rate of the feeding mechanism is controlled by the rotation speed. It should be noted that the rotation speed signal in this embodiment of the invention is used to control the rotation speed of the feeding mechanism. For example, the higher the rotation speed, the greater the powder feeding rate, and the lower the rotation speed, the smaller the powder feeding rate.

[0057] In this embodiment, a control signal is generated based on the ratio of the initial powder feeding time to the target powder feeding time, thereby adjusting the rotational speed of the powder feeding mechanism. The rotational speed can be adjusted by changing the drive current. For example, if the target powder amount is 30g, the initial powder feeding speed is 80r / min, and the initial powder feeding time t0 is 35s, and the target powder feeding time t1 is 28s, then the ratio n of the initial powder feeding time to the target powder feeding time is 1.25. Based on this ratio, the initial powder feeding speed is calibrated to the target powder feeding speed, resulting in a calibrated target powder feeding speed of 100r / min. The target powder feeding speed is then output to ensure the feeding mechanism feeds the powder at the target speed.

[0058] In this embodiment, the control signal is a rotation speed signal, which makes the feeding mechanism highly accurate and the target powder feeding rate easy to adjust.

[0059] In some embodiments of the present invention, the mixing method further includes: Obtain the powder weight and powder dispensing time; The initial powder supply rate is determined based on the powder output weight and powder output time.

[0060] In this embodiment, the initial powder supply rate is determined by calculating the powder weight dispensed by the powder supply mechanism per unit time. For example, the powder weight dispensed per unit time can be obtained using an active acquisition method or an automatic acquisition method.

[0061] Optionally, an active acquisition method is used: Upon initial use, the user receives the powder supplied by the mixing equipment (e.g., the powder supply mechanism of the mixing equipment) within a set time using a container and weighs the powder. The initial powder supply rate is determined based on the weight of the powder and the set time. For example, the initial powder supply rate = weight of powder / set time.

[0062] Optionally, an automatic acquisition method is used: a weighing mechanism is installed at the outlet of the powder supply mechanism. The container is placed on the weighing mechanism, and its initial weight is recorded. Then, the powder supply mechanism begins supplying powder. After a set powder supply time, the weighing mechanism records the weight of the container after powder supply. The initial powder supply rate is determined based on the weight difference before and after powder supply, as well as the set time. For example, the initial powder supply rate = the weight difference of the powder / the set time.

[0063] The methods described above can effectively obtain the initial toner supply rate, thus providing a basis for obtaining the target toner supply rate. Of course, the methods for obtaining the initial toner supply rate are not limited to the above embodiments, and those skilled in the art can set them according to actual needs.

[0064] In some embodiments of the present invention, this mixing method can be used directly for liquid supply. For example, a user wants to add a set amount of liquid to a container. After the container is placed under the liquid supply mechanism, the desired target liquid volume is input. The mixing device has a set liquid supply rate. After obtaining the target liquid volume, the mixing device generates a liquid supply duration based on the target liquid volume and the liquid supply rate. Based on the liquid supply duration, the liquid supply mechanism is activated to directly supply liquid to the container. In this mode, only liquid is supplied to the container, and no powder is supplied, so that the user can obtain the set amount of liquid.

[0065] In some embodiments of the present invention, the mixing method can be directly used for powder supply. For example, a user wants to add a set weight of powder to a container. After the container is placed under the powder supply mechanism, the user inputs the desired target powder amount. The powder supply mechanism supplies powder according to the initial powder supply rate. After obtaining the target powder amount, the mixing device generates a target powder supply duration based on the target powder amount and the initial powder supply rate. According to the target powder supply duration, the powder supply mechanism starts to directly supply powder to the container. In this mode, only powder is supplied to the container, not liquid, so that the user can obtain the set amount of powder.

[0066] Alternatively, the powder supply mechanism can supply powder according to a target powder supply rate. After obtaining the target powder quantity, the mixing equipment generates a target powder supply duration based on the target powder quantity and target powder supply rate. According to the target powder supply duration, the powder supply mechanism starts to directly supply powder into the container. In this mode, only powder is supplied to the container, and no liquid is supplied. This method also allows the user to obtain the set amount of powder.

[0067] When the powder is being supplied by the powder supply mechanism, if the distance between the container opening and the supply port of the powder supply mechanism is too large, the powder is prone to scattering, resulting in powder loss and pollution of the surrounding environment. If the distance between the container opening and the supply port of the powder supply mechanism is too small, it can make it difficult to pick up and put down the container. In this embodiment, before powder supply, the height of the container is adjusted to ensure that the distance between the container and the supply port of the powder supply mechanism is appropriate.

[0068] For example, the mixing equipment includes a lifting mechanism. The lifting mechanism is used to carry and lift the container. When the container is placed on the lifting mechanism, the controller of the mixing equipment sends a fifth control signal to the lifting mechanism. This fifth control signal drives the lifting mechanism to rise, causing it to move the container closer to the feeding port of the feeding mechanism, thereby reducing the distance between the feeding port and the container's opening. When the container's opening reaches a predetermined position, the controller generates a sixth control signal. This sixth control signal drives the lifting mechanism to descend a set distance, ensuring that the distance between the container's opening and the feeding port reaches a suitable level.

[0069] Optionally, the predetermined position can be the position where the opening of the container abuts against the housing surrounding the feed port. For example, the housing is equipped with a pressure sensor. When the opening of the container collides with the pressure sensor and reaches a set pressure value, it indicates that the opening of the container has reached the position of the housing surrounding the feed port. The controller then controls the lifting mechanism to descend so that the distance between the opening of the container and the feed port reaches a suitable distance. Alternatively, the housing is equipped with a position sensor. When the position sensor detects that the container has reached a predetermined position, the controller controls the lifting mechanism to descend so that the distance between the opening of the container and the feeding port reaches a suitable distance.

[0070] Of course, the predetermined position can also be any other position below the feed port, and those skilled in the art can set it according to actual needs.

[0071] A second embodiment of the present invention provides a brewing and mixing device. This device includes a controller. The controller operates the brewing and mixing method described in this invention.

[0072] In some embodiments of the present invention, the mixing equipment includes a base, a powder supply mechanism, a liquid supply mechanism, and a discharge device, wherein the discharge device has a mixing space below it for placing a container.

[0073] like Figure 8As shown, the mixing equipment includes a base 1000, a controller, a liquid supply mechanism, a powder supply mechanism, a discharge device, a lifting mechanism, and an operating interface. The controller, liquid supply mechanism, powder supply mechanism, lifting mechanism, and operating interface are housed within the base 1000. The controller may include, for example, a microcontroller (MCU). The controller receives user-input parameters such as the target liquid volume and target powder volume, performs various calculations for the mixing method, such as the liquid supply duration, target powder supply duration, and target powder supply rate, and generates the aforementioned first to sixth control signals to control the coordinated operation of the liquid supply mechanism, powder supply mechanism, and lifting mechanism. Optionally, the controller has a built-in memory that can store parameters such as the initial powder supply rate and preset delay duration for various powders.

[0074] The liquid supply mechanism includes a storage tank 2010, a pump 2020, and a heater 2040, used to output liquid at a set temperature and volume according to a control signal. The pump 2020 is connected between the discharge device and the storage tank 2010. The heater 2040 is used to heat the liquid inside the storage tank 2010.

[0075] The powder feeding mechanism adopts a spiral feeding method. It outputs a set weight of powder according to a control signal. The powder feeding mechanism includes a powder storage bin 3010, a spiral feed rod 3020, and a stepper motor 3030. A cover 1010 is provided on the base 1000. The stepper motor 3030 is installed inside the cover 1010. The cover 1010 is used to cover the powder storage bin 3010. The spiral feed rod 3020 is installed inside the powder storage bin 3010. After the cover 1010 is closed, the output shaft of the stepper motor 3030 is connected to the spiral feed rod 3020. The discharge device is located below the powder storage bin 3010. For example, the powder storage bin 3010 forms an inverted conical structure. The discharge device is located below the conical structure.

[0076] A flushing space is formed between the dispensing device and the lifting mechanism. The lifting mechanism includes a lifting platform 5010 and a position sensor. The lifting platform 5010 is used to place containers such as baby bottles and water cups, and raises and lowers the containers according to control signals to ensure that the distance between the opening of the container and the dispensing device is appropriate. The position sensor is used to sense the position of the container.

[0077] The user interface includes a touch panel and a communication module. The touch panel connects to the controller via the communication module. Users input parameters and view the operating status of the brewing equipment through the user interface. For example, users can input the target liquid volume, target powder volume, and beverage temperature via the touch panel. The touch panel can display the operating mode (e.g., brewing mode, water supply mode, powder supply mode), liquid temperature, etc.

[0078] like Figures 2 to 7As shown, the discharge device includes: a main body 100, the main body 100 being provided with a first outlet 101 and a plurality of second outlets 104, the first outlet 101 being connected to the powder supply mechanism for supplying powder, the second outlets 104 being connected to the liquid supply mechanism for supplying liquid, and the liquid supply path of the second outlet 104 and the powder supply path of the first outlet 101 intersecting in the mixing space.

[0079] In this embodiment, the main body 100 serves as the primary support structure for the discharging device. The main body 100 is made of metal, plastic, or similar materials. The shape of the main body 100 can be determined according to the overall structure of the mixing equipment, for example, it can be cylindrical or square. A first outlet 101 and multiple second outlets 104 are both located on the main body. The first outlet 101 and multiple second outlets 104 are situated above the mixing space. The powder supply mechanism supplies powder through the first outlet 101. The liquid supply mechanism supplies liquid through the multiple second outlets 104. Since the liquid supply path of the second outlet 104 intersects with the powder supply path of the first outlet 101 within the mixing space, the powder and liquid can mix during their descent within the mixing space, and the final mixed powder and liquid fall into the container. This mixing equipment has a simple structure and does not require a mixing chamber.

[0080] In some embodiments of the present invention, the discharge device further includes a conveying pipeline 102, which is connected to a plurality of second outlets 104, which are arranged around the axis of the first outlet 101.

[0081] Specifically, the delivery pipeline 102 is a pipeline used for transporting liquids. The material of the second pipeline is usually metal, plastic, etc. One end of the delivery pipeline 102 can be connected to a liquid supply mechanism 500 such as a water pump or a water storage tank, and the other end can be connected to multiple second outlets 104 to realize the diversion and transportation of liquids. The inner diameter of the delivery pipeline 102 can be set according to the liquid transportation volume, and is not limited here.

[0082] The first outlet 101 penetrates the main body 100. The diameter of the first outlet 101 can be set according to the powder conveying volume and is not limited here. The extension direction of the first outlet 101 is usually vertical to allow the powder to fall naturally under gravity, or it can be set in an inclined direction according to the overall layout of the mixing equipment to ensure that the first outlet 101 can stably convey the powder. Optionally, the cross-section of the first outlet 101 is circular, rectangular, elliptical, etc. The second outlet 104 is a branch outlet of the conveying pipeline 102. The number of second outlets 104 can be set according to the mixing requirements. Multiple second outlets 104 working together can achieve uniform liquid conveying. The diameter of the second outlet 104 is usually smaller than the diameter of the first outlet 101, for example, 1mm-3mm, to form a fine liquid flow and improve the mixing effect with the powder.

[0083] Optionally, the powder is a powdered material that needs to be mixed. Examples of powders include milk powder, coffee powder, protein powder, oatmeal powder, and other powdered raw materials for mixing beverages. The liquid is used to mix the powder. For example, the liquid could be drinking water, or other liquids depending on the mixing requirements, such as milk when mixing certain nutritional powders.

[0084] like Figures 2 to 4 As shown, the conveying pipe 102 is connected to the main body 100, for example, by means of snap-fit ​​connection, threaded connection, or integral molding. The end of the conveying pipe 102 is provided with a plurality of second outlets 104. The plurality of second outlets 104 are arranged around the axis of the first outlet 101, so that the liquid sprayed from the second outlets 104 can surround the powder flowing out of the first outlet 101 and can intersect with the falling powder, achieving direct contact and mixing of the two during their descent.

[0085] In use, the powder falls from the first outlet 101, and the liquid is sprayed out from multiple second outlets 104 distributed along the axis surrounding the first outlet 101. The powder and liquid are mixed at the first outlet 101. Optionally, the powder and liquid can be mixed inside the first outlet 101 or below it. A container, such as a water cup or baby bottle, is placed below the dispensing device to directly receive the mixed powder and liquid, eliminating the need for a separate mixing chamber.

[0086] In this embodiment of the invention, by arranging multiple second outlets 104 around the axis of the first outlet 101, direct mixing of powder and liquid is achieved at the first outlet 101 without the need for a separate mixing chamber, thereby avoiding the problem of material residue on the inner wall of the mixing chamber. Therefore, there is no need to clean the mixing chamber after each use, which greatly improves the user's convenience.

[0087] In addition, multiple second outlets 104 are arranged around the axis of the first outlet 101, which allows the liquid to wrap around the powder from multiple directions, improving the mixing uniformity of the two, avoiding local agglomeration, and better enabling the first material to be evenly stressed, converge towards the axis and fall into the receiving container; in addition, the user can directly receive the mixed powder and liquid below the first outlet 101, which is convenient to operate.

[0088] In some embodiments of the present invention, the first outlet 101 includes a first outlet end 1011 and a first inlet end 1012 opposite to the first outlet end 1011. A connecting pipe 103 is arranged around the axis of the first outlet 101. The connecting pipe 103 is connected to the conveying pipe 102. The connecting pipe 103 has a plurality of second outlets 104. The second outlet 104 includes a second inlet end 1014 connected to the outlet of the connecting pipe 103 and a second outlet end 1013 for liquid discharge.

[0089] like Figures 4 to 6 As shown, the first outlet 101 includes a first outlet end 1011 and a first inlet end 1012 opposite to the first outlet end 1011. The first outlet end 1011 refers to the end of the first outlet 101 used to discharge powder, that is, the powder is discharged from the first outlet end 1011 to the external space, such as the receiving space described below. The first outlet 101 is divided into a first inlet end 1012 along the material conveying direction, that is, the end closer to the material conveying mechanism 400 and the first outlet end 1011, that is, the end away from the material conveying mechanism 400 used for discharging material. A connecting pipe 103 is arranged around the axis of the first outlet 101. A plurality of second outlets 104 are opened on the connecting pipe 103.

[0090] like Figures 3 to 6 As shown, the connecting pipe 103 is arranged around the axis of the first outlet 101. The connecting pipe 103 is used to connect the conveying pipe 102 with multiple second outlets 104. The interior of the connecting pipe 103 forms an annular cavity 105. Optionally, the connecting pipe 103 is made of metal or plastic. The connecting pipe 103 is fixed to the body part 100 in a manner surrounding the axis of the first outlet 101. For example, the connecting pipe 103 can be integrally formed with the body part 100 or connected by welding, snap-fit ​​connection, or other methods. The end of the conveying pipe 102 is sealed to the interface opened on the side of the connecting pipe 103, which allows the liquid conveyed by the conveying pipe 102 to enter the cavity 105 of the connecting pipe 103. The second outlet 104 includes a second inlet end 1014 connecting to the outlet of the connecting pipe 103 and a second outlet end 1013 for liquid discharge. Multiple second outlets 104 are evenly opened in the connecting pipe 103 and distributed along the circumference of the connecting pipe 103. Liquid enters from the second inlet end 1014 and is ejected from the second outlet end 1013, thereby realizing the diversion and transportation of liquid from the conveying pipeline 102 to the connecting pipeline 103, and then to the multiple second outlets 104.

[0091] The connecting pipe 103 enables the centralized arrangement of multiple second outlets 104 and the diversion and delivery of liquid. The connecting pipe 103 is arranged around the first outlet 101, which can more accurately control the position of multiple second outlets 104 relative to the first outlet 101, ensuring that the liquid can be accurately sprayed around the powder, further improving the mixing uniformity.

[0092] In some embodiments of the present invention, the interior of the connecting pipe 103 forms a cavity 105, the width of the cavity 105 in the direction perpendicular to the axis of the first outlet 101 gradually decreases from the side near the first inlet end 1012 to the side near the first outlet end 1011, at least in a local area, and the radial dimension of the second outlet 104 gradually decreases from the side near the second inlet end 1014 to the side near the second outlet end 1013, at least in a local area.

[0093] like Figures 5 to 6 As shown, cavity 105 is used to contain and transport liquid. Cavity 105 is an annular hollow structure. Cavity 105 is connected to transport pipeline 102. Cavity 105 is an intermediate channel for liquid to flow from transport pipeline 102 to multiple second outlets 104. The axial direction of the first outlet 101 is as follows... Figure 5 As shown by the vertical dashed line, the width of the cavity 105 in the direction perpendicular to the axis of the first outlet 101 gradually decreases, at least in a local area, from the side near the first inlet end 1012 to the side near the first outlet end 1011. This arrangement allows the cavity 105 to collect liquid more effectively.

[0094] like Figure 5 , Figure 6 As shown, a first cavity wall 106 surrounds and forms a first outlet 101. A second cavity wall 107 surrounds and connects to the first cavity wall 106. A cavity 105 is formed between the first cavity wall 106 and the second cavity wall 107. The lower part of the second cavity wall 107 bends towards the side closer to the first cavity wall 106 to form a second conical section 109. Powder is conveyed along the axis of the first outlet 101. For example, the axis of the first outlet 101 is generally vertical, and the direction perpendicular to this axis is horizontal. The width in the direction perpendicular to the axis of the first outlet 101 gradually decreases, at least in a local area, from the side closer to the first inlet end 1012 towards the side closer to the first outlet end 1011. This arrangement increases the liquid pressure, allowing the liquid to converge towards the second outlet 104 within the cavity 105, and further increases the flow rate of the liquid flowing through the second outlet 104, improving the mixing effect of the powder and liquid.

[0095] Furthermore, the radial dimension of at least a localized region of the second outlet 104 gradually decreases from the second inlet end 1014 towards the side closer to the second outlet end 1013. The radial dimension of the second inlet end 1014 of the second outlet 104 is larger, while the radial dimension of the side of the second outlet 104 closer to the second outlet end 1013 is smaller, forming a cone-like structure. Figure 5The first conical section 110 in the connecting pipe 103. The cavity 105 inside the connecting pipe 103 provides liquid to the second outlet 104. The second inlet end 1014 of the second outlet 104 is connected to the cavity 105, and the second outlet end 1013 of the second outlet 104 faces the first outlet end 1011 of the first outlet 101, which allows the second inlet end 1014 of the second outlet 104 to collect liquid more efficiently.

[0096] Furthermore, as the liquid flows through the second outlet 104, the radial dimension of at least a local area of ​​the second outlet 104 gradually decreases, resulting in a gradual increase in the liquid velocity. This generates a greater impact force, which helps to disperse the powder, prevent powder agglomeration, and improve mixing uniformity. The high-speed liquid also has a flushing effect on the outlet end 1011 of the first outlet 101, preventing powder from adhering to the first outlet end 1011.

[0097] Optionally, the first conical segment 110 is connected to the second conical segment 109, and the angle between the centerline of the second conical segment 109 and the axis of the first outlet 101 (e.g., ...) is... Figure 6 (As shown in b) is smaller than the centerline of the first conical segment 110 and the axis of the first outlet 101 (as shown in b). Figure 6 The angle shown in Figure a) is such that the liquid pressure is increased, the liquid flow rate is improved, and the mixing effect of powder and liquid is enhanced.

[0098] In some embodiments of the present invention, the end face of the first outlet end 1011 faces the axis of the first outlet 101, and the second outlet end 1013 is disposed on the end face of the first outlet end 1011.

[0099] like Figure 5 , Figure 6 As shown, the connecting pipe 103 includes a first cavity wall 106 near the first outlet 101 and a second cavity wall 107 away from the first outlet 101. The bottoms of the first cavity wall 106 and the second cavity wall 107 are connected to form a first outlet end 1011. The outer surface of the first outlet end 1011 is the end face of the first outlet end 1011, and the second outlet end 1013 of the second outlet 104 is located on the end face of the first outlet end 1011. The side of the first cavity wall 106 away from the cavity 105 forms the inner wall of the first outlet 101. The end face of the first outlet end 1011 faces the axis of the first outlet 101. For example, the angle between the end face of the first outlet end 1011 and the inner wall of the first outlet 101 is an obtuse angle, that is, the angle range is greater than 90° and less than 180°, so that the end face of the first outlet end 1011 faces the axis of the first outlet 101.

[0100] In this embodiment, the end face of the first outlet 1011 faces the axis of the first outlet 101. This arrangement, on the one hand, avoids the accumulation of powder at the corner of the inner wall of the outlet 1011, reducing powder residue; on the other hand, the outwardly expanding outlet 1011 allows the powder to have a larger diffusion range when flowing out, making it easier for the powder to come into contact with and mix with the liquid sprayed from the multiple second outlets 104, thus improving the mixing efficiency.

[0101] In addition, such as Figure 6 , Figure 7 As shown, the second outlet end 1013 of the second outlet 104 is located on the end face of the first outlet end 1011, so that the liquid sprayed from the multiple second outlets 104 can be concentrated towards the axis of the first outlet 101, which allows the liquid to be mixed more fully with the powder.

[0102] In some embodiments of the present invention, the inner edge of the first inlet end 1012 forms an arc surface structure.

[0103] As previously mentioned, the first inlet end 1012 of the first outlet 101 refers to the end of the first outlet 101 closest to the material conveying mechanism 400. The first inlet end 1012 of the first outlet 101 is used to receive powder. The first inlet end 1012 is arranged opposite to the first outlet end 1011, that is, the powder enters the first outlet 101 from the first inlet end 1012 and then falls from the first outlet end 1011. The powder conveying mechanism 400 is used to convey the powder to the first outlet 101. The material conveying device includes, for example, a screw feeder, a pneumatic feeding device, a gravity feeding channel, etc.

[0104] In this embodiment, the inner edge of the first inlet end 1012 does not adopt a right-angle corner structure, but forms an arc surface structure. That is, the inner edge from the discharge port of the material conveying mechanism 400 to the first outlet 101 is smoothly transitioned through the arc surface structure. The smooth arc surface structure reduces the flow resistance of the powder at the inlet end 1012, ensuring that the powder can smoothly and stably enter the first outlet 101, thereby improving the conveying efficiency of the powder.

[0105] In some embodiments of the invention, at least a portion of the axis of the plurality of second outlets 104 passes through the projection region of the outlet end of the first outlet 101 along the direction of gravity.

[0106] Optionally, the axes of the multiple second outlets 104 all pass through the projection area of ​​the outlet end of the first outlet 101 along the direction of gravity. Alternatively, the axis of a portion of the multiple second outlets 104 passes through the orthographic projection area of ​​the first outlet 101 along the outlet direction, while the axis of another portion does not pass through the projection area of ​​the first outlet 101 along the gravity direction at the outlet end.

[0107] In this embodiment, the first material falls from the first outlet 101 along the direction of gravity. During the fall, the first material is located within the projection area of ​​the first outlet 101 along the direction of gravity. At least a portion of the second outlets 104 have axes that pass through the projection area of ​​the first outlet 101 along the direction of gravity, thereby enabling the second material ejected from the second outlets 104 to be fully mixed with the falling first material.

[0108] In some embodiments of the invention, at least a portion of the axes of the plurality of second outlets 104 intersect on the axis of the first outlet 101 in the outlet direction.

[0109] Optionally, the axes of the multiple second outlets 104 all intersect on the axis of the first outlet 101 in the outlet direction; Alternatively, the axes of a portion of the multiple second outlets 104 may intersect on the axis of the first outlet 101 in the outlet direction, while the axes of another portion may not intersect on the axis of the first outlet 101 in the outlet direction.

[0110] In this embodiment, at least some of the axes of the plurality of second outlets 104 intersect on the axis of the first outlet 101 in the outlet direction, which makes the liquid sprayed from the plurality of second outlets 104 more concentrated, effectively avoiding uneven mixing of liquid and powder, and powder dispersion.

[0111] In some embodiments of the present invention, a plurality of second outlets 104 are evenly distributed along the circumference of the first outlet 101.

[0112] like Figure 4 As shown, multiple second outlets 104 are located on the end face of the first outlet 1011 of the first outlet 101 and are evenly distributed around the axis of the first outlet 101. This arrangement allows the liquid ejected from the multiple second outlets 104 to be evenly mixed with the powder from all directions, improving the uniformity of the mixing.

[0113] In some embodiments of the present invention, the plurality of second outlets 104 are divided into at least two groups, each group including at least two second outlets 104, the axes of the at least two second outlets 104 intersecting on the axis of the first outlet 101 in the outlet direction, and the intersection position of the axes of the second outlets 104 in each group on the axis of the first outlet 101 is different.

[0114] In this embodiment, the discharge device includes multiple second outlets 104. These second outlets 104 are divided into two or more groups. Each group includes at least two second outlets 104. The axes of the multiple second outlets 104 in each group intersect on the axis of the first outlet 101 in the outlet direction. Furthermore, the intersection positions of the axes of the second outlets 104 in different groups on the axis of the first outlet 101 are different. This arrangement allows the powder to be mixed sequentially with the liquid sprayed from different groups of second outlets 104 during its descent, thereby effectively improving the mixing efficiency of the powder and liquid.

[0115] In some embodiments of the present invention, each group of second outlets is distributed on the same ring, and the second outlets in each group are evenly distributed. Alternatively, the second outlets of each group are distributed on different concentric rings, and the axes of the second outlets 104 on different rings intersect at different positions on the axis of the first outlet 101, and the second outlets in each group are evenly distributed.

[0116] In this embodiment, it can be, as follows: Figure 4 As shown, multiple second outlets 104 in each group are arranged around the axis of the first outlet 101 and located on the same ring, with the second outlets 104 in each group being evenly distributed. Optionally, the ring can be a circular ring, a rectangular ring, an elliptical ring, etc. For example, multiple second outlets 104 in each group are evenly distributed on the end face of the first outlet end 101 of the first outlet 101 and arranged around the axis of the first outlet 101. Each group includes at least two second outlets 104. The axes of the multiple second outlets 104 in each group intersect on the axis of the first outlet 101 in the outlet direction. Moreover, the intersection positions of the axes of the second outlets 104 in different groups on the axis of the first outlet 101 are different. This arrangement allows the powder to be mixed sequentially with the liquid sprayed from different groups of second outlets 104 during the falling process, thereby effectively improving the mixing efficiency of powder and liquid, and the structure of the discharge device is simple.

[0117] It could also be, such as Figure 7As shown, multiple second outlets 104 in the same group are located on the same ring, and the multiple second outlets 104 in the same group are evenly distributed on the same ring. Multiple second outlets in different groups are located on different rings. The multiple rings are concentrically arranged. Optionally, the rings can be circular rings, rectangular rings, elliptical rings, etc. The axes of multiple second outlets 104 in the same group intersect at the same position on the axis of the first outlet 104. The second outlets 104 in different groups intersect at different positions on the axis of the first outlet 101. Each group includes at least two second outlets 104. The axes of multiple second outlets 104 in each group intersect on the axis in the outlet direction of the first outlet 101. Moreover, the intersection positions of the axes of the second outlets 104 in different groups on the axis of the first outlet 101 are different. This arrangement allows the powder to be mixed sequentially with the liquid sprayed from different groups of second outlets 104 during the falling process, thereby effectively improving the mixing efficiency of powder and liquid.

[0118] In some embodiments of the present invention, the portion of the connecting pipe 103 near the second outlet 104 protrudes from the body portion 100 to form a protrusion, the outer side wall of the protrusion forming a conical surface, the conical surface forming an acute angle with the axis of the first outlet 101.

[0119] like Figure 4 As shown, the portion of the connecting pipe 103 near the second outlet 104 protrudes outward relative to the lower surface of the main body 100 to form a protrusion. The height of the protrusion can be set according to actual needs. The shape of the protrusion matches the shape of the connecting pipe 103, for example, it is an annular protrusion.

[0120] The protrusion guides the powder, preventing it from scattering as it falls from the first outlet 101. It also protects the second outlet 104 from damage caused by impacts from external objects. The protrusion's design facilitates user observation of the powder and liquid discharge, enhancing the user experience. Furthermore, the protrusion allows for easy placement of containers used to receive the mixed powder and liquid.

[0121] like Figure 5 , Figure 6 As shown, the lower part of the second cavity wall 107 slopes towards the side closer to the first outlet 101 to form a ramp 108. The ramp 108 forms a conical surface, causing the protrusion to have a structure in which the outer diameter gradually decreases from top to bottom. This structure facilitates the fitting of the protrusion with the container. During container movement, the container can smoothly abut against the support tray 601, allowing the container to reach a centered position as much as possible.

[0122] In some embodiments of the present invention, such as Figure 2 , Figure 3 , Figure 5As shown, the discharge device also includes an opening and closing assembly. The opening and closing assembly controls the conveying of the powder. The assembly includes a power unit and a baffle 201. The main body 100 is provided with a chute 111. The baffle 201 is slidably disposed within the chute 111. The baffle 201 has a feed port 205. A rack 202 is mounted on the baffle 201. The power unit includes a motor 203 and a gear 204. The gear 204 is mounted on the shaft of the motor 203. The gear 204 meshes with the rack 202. The motor 203 drives the gear 204 to rotate, which in turn drives the baffle 201 to slide along the chute 111 via the rack and pinion mechanism. When the feed port 205 is opposite to the first outlet 101, the powder falls through the feed port 205 and the first outlet 101. Simultaneously, liquid is ejected from the second outlet 104 through the conveying pipe 102 and the connecting pipe 103 to mix with the powder.

[0123] When the feed inlet 205 is misaligned with the first outlet 101, the baffle 201 closes the first outlet 101, and the powder stops falling. At the same time, the liquid supply stops.

[0124] The following section introduces the different working modes of the milk powder mixing machine, using milk powder preparation as an example.

[0125] Mixing modes: The user places the baby bottle on the lifting platform 501. The controller of the mixing equipment sends a fifth control signal to the lifting platform 501. The fifth control signal drives the lifting platform 501 to rise, causing it to move the container closer to the feeding port of the feeding mechanism, thereby reducing the distance between the feeding port and the opening of the container. When the opening of the container reaches the predetermined position, the controller drives the lifting platform 501 to descend a set distance, so that the distance between the opening of the container and the feeding port reaches an appropriate level.

[0126] The user inputs a target liquid volume of 300ml, a target powder volume of 30g, and a beverage temperature of 50℃ via the user interface. Heater 204 heats the water in storage tank 201. The controller calculates a liquid supply rate of 10ml / s based on the mixing method, resulting in a liquid supply duration of 30s; the target powder supply speed is 100r / min, with a target powder supply duration of 28s. During mixing, the controller first sends a control signal. The liquid supply mechanism begins supplying liquid at a rate of 10ml / s, with water spraying out through outlet 203 and falling into the container. After a 1-second delay, the powder supply mechanism begins supplying powder at a target powder supply rate of 100r / min. Milk powder falls through outlet 304. At this time, water and milk powder mix together during the descent and enter the container. Powder supply stops after 28s; liquid supply stops after 30s.

[0127] Water supply mode: The user inputs a target liquid volume of 100ml and a water temperature of 50℃ through the operation interface. Heater 204 heats the water in storage tank 201. After obtaining the target liquid volume, the controller generates a supply duration (e.g., 10s) based on the target liquid volume (e.g., 100ml) and the supply rate (e.g., 10ml / s). The controller then controls the supply mechanism to open based on the supply duration to directly supply liquid into the container, stopping the supply after 10s.

[0128] Powder supply mode: The user inputs a target powder quantity of 30g through the user interface. The powder supply mechanism supplies powder according to the initial powder supply rate. After obtaining the target powder quantity, the controller generates an initial powder supply duration (e.g., 35s) based on the target powder quantity and the initial powder supply speed (e.g., 80r / min). Based on the initial powder supply duration and the initial powder supply speed, the controller starts the powder supply mechanism to directly supply powder into the container. Powder supply stops after 35 seconds.

[0129] This beverage preparation equipment does not require a mixing chamber; the beverage can be directly poured into the container. Furthermore, the equipment can operate in multiple modes.

[0130] According to a third embodiment of the present invention, a brewing and mixing system is provided. The brewing and mixing system includes a brewing and mixing device and a movable device, the brewing and mixing device being communicatively connected to the movable device, and the brewing and mixing device executing the brewing and mixing method described in the present invention after receiving a control command sent by the movable device.
