Description

Powder brewing machine and beverage brewing method Technical Field

[0001] The embodiments of the present invention relate to the technical field of automatic powder dispensing, and in particular to a powder dispensing machine and a beverage dispensing method. Background Art

[0002] The powder drink making machines with automatic functions on the market, such as the powder making machine with patent number CN115813200A, use a powder adding method based on unit volume to achieve unit volume-by-unit volume addition, while the water adding method uses a flow meter to calculate the flow rate to achieve the required amount of water addition. The errors of these two methods are large, and the beverages prepared, such as milk, have improper concentration ratios and cannot meet the requirements of scientific feeding of infants and young children.

[0003] Specifically, the specific details of the current powder printing machine include:

[0004] 1. The powder is mixed with warm water in the mixing chamber to form milk before flowing into the container;

[0005] 2. After all the milk flows into the container, the weighing device is used to weigh it, and the water-to-powder ratio is judged to see whether it meets the requirements and whether it needs to be supplemented;

[0006] 3. The basis for judgment is to calculate the powder amount by the weight of milk and water output, but the weighing device cannot weigh the weight of water alone, so the water output is determined by the flow meter;

[0007] 4. The tolerance of the flow meter is large, and the calculated powder amount will also have corresponding deviations;

[0008] 5. Failure to meet the requirements for scientific feeding of infants and young children.

[0009] In summary, the existing solutions for adding water and powder will have relatively large errors, resulting in improper concentration ratios of the prepared drinks, especially the milk, such as overnutrition or malnutrition, which affects the baby's health. Summary of the Invention

[0089] It should also be understood that although the invention has been described with reference to certain specific examples, those skilled in the art will be able to realize many other equivalent forms of the invention that have the characteristics recited in the claims and are therefore within the scope of protection defined thereby.

[0090] The above and other aspects, features and advantages of the present disclosure will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0091] Specific embodiments of the present disclosure will be described hereinafter with reference to the accompanying drawings; however, it should be understood that the disclosed embodiments are merely examples of the present disclosure, which may be implemented in a variety of ways. Well-known and / or repetitive functions and structures are not described in detail to avoid obscuring the present disclosure with unnecessary or redundant detail. Therefore, the specific structural and functional details disclosed herein are not intended to be limiting, but rather serve merely as a basis and representative basis for the claims to teach those skilled in the art to variously employ the present disclosure with substantially any suitable detailed structure.

[0092] This description may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," each of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0093] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0094] As shown in FIG1 and FIG2 , an embodiment of the present invention provides a powder brewing machine, comprising:

[0095] Body 1;

[0096] A powder discharge device 2 is provided in the machine body 1 and is used to discharge a specified amount of powder;

[0097] A water tank 3 is provided in the body 1 and is used to hold brewing water;

[0098] a hot water supply device, provided in the machine body 1, for obtaining part or all of the brewing water in the water tank 3 and heating it;

[0099] The liquid shaking mechanism includes a liquid shaking device 10 and a weighing device 20. The liquid shaking device 10 is used to fix the container 30 and drive the container 30 to rotate so that the powder and heated brewing water in the container 30 are fully mixed. The weighing device 20 is used to weigh the container 30 in real time to determine the weight of the brewing water and powder delivered to the container 30.

[0100] The dry-wet separation device 4 is provided in the machine body 1 and is connected to the powder feeding device 2 and the hot water supply device respectively, and is used to independently output brewing water and powder based on different channels;

[0101] The controller is arranged in the body 1 and is connected to the powder feeding device 2, the hot water supply device, and the liquid shaking mechanism. The controller can receive brewing information input by the user and control the operation of the powder feeding device 2, the hot water supply device, and the liquid shaking mechanism based on the brewing information to complete the brewing of the specified beverage.

[0102] The powder brewing machine in this embodiment can be used to brew milk powder, coffee, and other beverages using powdered granules, with no specific limitation. By integrating a hot water supply device, a powder dispensing device 2, a liquid shaking mechanism, a dry-wet separation device 4, and a controller, the powder brewing machine can automatically and accurately determine the amount of water and powder required for this brewing according to the water-to-powder ratio and the total amount of brewing input by the user, and control the powder dispensing device 2, the liquid shaking mechanism, and the hot water supply device to operate in coordination, achieving accurate dispensing and full fusion of water and powder, thereby preparing a beverage that meets the user's needs. In particular, when brewing formula milk, the brewed formula milk can be neither too thick nor too thin, and the temperature is suitable for infant consumption, providing great convenience for the user.

[0103] In addition, the setting of the dry-wet separation device 4 allows water and powder to be transported to the container 30 based on different channels respectively, thereby isolating water and powder. The shaking operation is carried out in the container 30, which can effectively increase the distance between the container 30 and the powder feeding device 2, preventing water vapor from entering the powder feeding device 2, causing the powder in the powder feeding device 2 to become damp and deteriorate.

[0104] Specifically, as shown in FIG3 , the powder discharging device includes a powder storage box 100 and a top cover 200 , wherein the powder storage box 100 is used to hold powder and is cylindrical in shape, having a space for accommodating powder. Referring to FIG4 , the top of the powder storage box 100 has an opening, and the top cover 200 is detachably fixed to the top of the powder storage box 100, that is, the opening of the powder storage box 100 , to prevent the powder in the powder storage box 100 from overflowing from the top of the powder storage box 100 . The bottom of the powder storage box 100 is provided with a powder discharging port 1001 , through which powder can be discharged. For example, the powder falls from the powder discharging port 1001 into a container located below the powder discharging device.

[0105] 5 , 6 and 7 , in addition to the powder storage box 100 and the top cover 200 , the powder discharging device further includes a rotating box 300 and a baffle 400 .

[0106] 8 and 9 , the rotating box 300 can also be configured as a cylindrical shape, and the top of the rotating box 300 also has an opening. The bottom of the rotating box 300 is provided with a metering port 3001 connected to the outside of the rotating box 300. The rotating box 300 is slightly smaller than the powder storage box 100 so that the rotating box 300 can be arranged inside the powder storage box 100. The outer wall of the rotating box 300 is attached to the inner wall of the powder storage box 100, and the rotating box 300 can rotate relative to the powder storage box 100. When the powder discharging device needs to discharge powder, the metering port 3001 can be rotated to the top of the powder discharging port 1001, and the powder in the metering port 3001 can fall to the powder discharging port 1001 and be discharged through the powder discharging port 1001.

[0107] The quantitative port 3001 can be, but is not limited to, set to a rectangular port or a fan-shaped port. When the rotary box 300 rotates, the powder will tend to flow in the direction away from the center of the rotary box 300 as the rotary box 300 rotates. Therefore, in order to ensure that the quantitative port 3001 can be filled with powder (especially when the amount of powder in the powder discharging device is small), the quantitative port 3001 can be set at a position at the bottom of the rotary box 300 away from the center of the rotary box 300. For the above reasons, the powder discharging port 1001 and the powder outlet 4002 can preferably be set to a fan-shaped port corresponding to the quantitative port 3001. This is only used as an example and does not constitute a limitation to the scope of protection of the claims.

[0108] Referring again to FIG5 , the baffle plate 400 is located below the powder storage box 100 and is detachably connected to the rotating box 300 so as to rotate synchronously with the rotating box 300. Referring to FIG10 and FIG11 , the baffle plate 400 is provided with a powder outlet 4002 located just below the metering port 3001. When the powder outlet 4002 and the metering port 3001 are both misaligned with the powder outlet 1001, the rotating box 300 and the baffle plate 400 block the powder outlet 1001 from above and below the powder outlet 1001, respectively. The baffle plate 400 may be disc-shaped, and the outer edge of the disc may be bent upward to form a retaining edge 4001. During the powder discharging process, a very small amount of powder may enter the gap between the baffle plate 400 and the powder storage box 100. The upwardly bent retaining edge 4001 may prevent the powder that has entered the gap between the baffle plate 400 and the powder storage box 100 from falling through the gap. Of course, the baffle plate 400 can be disassembled regularly to clean or clear the powder feeding device.

[0109] The utility model sets a baffle 400 below the powder storage box 100, and the baffle 400 is provided with a powder outlet 4002 located directly below the metering port 3001 on the rotating box 300. When the powder discharging device does not need to discharge powder, the rotating box 300 and the baffle 400 can be rotated so that the powder outlet 4002 and the metering port 3001 are misaligned with the powder discharging port 1001 of the powder storage box 100, so that the rotating box 300 and the baffle 400 can respectively block the powder discharging port 1001 from above and below the powder discharging port 1001, thereby preventing small animals such as cockroaches and ants from entering the powder discharging device through the powder discharging port 1001 and causing pollution to the powder discharging device.

[0110] In addition, when the powder discharging device does not discharge powder, the rotating box 300 and the baffle 400 can respectively block the powder discharging port 1001 from above and below the powder discharging port 1001, and can also prevent moisture in the air from entering the powder discharging device from the powder discharging port 1001 to a certain extent, causing the powder in the powder discharging device to agglomerate, thereby affecting the powder discharging.

[0111] In one embodiment of the present application, referring again to FIG. 4 , a through hole 1002 is provided at the center of the bottom of the powder storage box 100 so that the rotating box 300 in the powder storage box 100 can be connected to the baffle 400 outside the powder storage box 100 through the through hole 1002 .

[0112] Specifically, referring to FIG9 , a downwardly projecting protrusion 3002 is provided at the center of the bottom of the rotating box 300. The protrusion 3002 can be designed as a cylinder. The lower end of the protrusion 3002 passes through the through-hole 1002 and extends below the powder storage box 100, so that the rotating box 300 can be connected to the baffle 400 via the protrusion 3002. For example, a slot or a buckle can be provided on the protrusion 3002.

[0113] Referring again to Figure 10 , the center of the baffle plate 400 is provided with an upwardly projecting boss, which can be shaped like a truncated cone. A circular connecting hole 4003 is provided on the boss, extending axially through the boss. The inner wall of the connecting hole 4003 is provided with a buckle or a slot, which cooperates with the buckle to achieve a removable connection between the baffle plate 400 and the rotating box 300. For example, the inner wall of the connecting hole 4003 can be provided with a buckle protruding toward the center of the connecting hole 4003, and the slot can be provided on the outer peripheral wall of the protrusion 3002. When the baffle plate 400 needs to be connected to the rotating box 300, the protrusion 3002 of the rotating box 300 is passed through the through hole 1002, the rotating box 300 can be kept stationary, the connecting hole 4003 of the baffle plate 400 is aligned with the protrusion 3002 of the rotating box 300, and the baffle plate 400 is pushed upward (of course, it is understandable that the baffle plate 400 can also be placed under the powder storage box 100, the baffle plate 400 is kept stationary, the protrusion 3002 of the rotating box 300 is aligned with the connecting hole 4003 of the baffle plate 400, and the rotating box 300 is pressed downward) until the buckle is buckled into the slot. When the baffle plate 400 needs to be disassembled from the rotating box 300, the rotating box 300 can be pulled upward or downward to disengage the buckle from the slot.

[0114] The rotating box 300 and the baffle plate 400 are coaxially arranged and connected so that they can rotate synchronously. The buckle and slot cooperate to achieve quick disassembly and assembly of the baffle plate 400 and the rotating box 300, facilitating quick disassembly and assembly when the powder feeding device needs to be cleaned or maintained.

[0115] In one embodiment of the present application, an upwardly protruding conical head 3003 is provided at the center of the upper surface of the bottom of the rotating box 300, wherein the conical head 3003 can be a truncated cone with a bottom diameter of 46 mm, a height of 10 mm, and a taper of 35°. Referring again to FIG8 , at least two fan-shaped conical bosses 3004 are provided around the circumference of the conical head 3003. For example, three conical bosses 3004 with an included angle of 120° or four conical bosses 3004 with an included angle of 90° are provided around the circumference of the conical head 3003. Of course, it is also understandable that the number of conical bosses 3004 can be set according to actual needs. This is merely an example and does not constitute a limitation on the scope of protection of the claims.

[0116] A fan-shaped conical boss 3004 protrudes upward from the upper surface of the bottom of the rotating box 300, and the conical boss 3004 has an inclined surface 3005. The quantitative port 3001 can be set at one end of the conical boss 3004 close to the inner wall of the rotating box 300. The specific reasons have been discussed and will not be repeated here.

[0117] The metering port 3001 is set on the conical boss 3004, so that during the rotation of the rotating box 300, the powder in the rotating box 300 is affected by the conical boss 3004 and rotates along with the rotating box 300. The rotating powder can be filled into the metering port 3001 of the conical boss 3004 and fill the metering port 3001.

[0118] In one embodiment of the present application, referring again to FIG. 5 and FIG. 6 , the powder discharging device further includes a fixed arm 500 .

[0119] 12 , the fixed arm 500 includes a reinforcing ring 5001, a baffle, and a spoiler structure 5002. The reinforcing ring 5001 is connected to the inner wall of the powder storage box 100. The top of the rotating box 300 is lower than the top of the powder storage box 100, and the reinforcing ring 5001 is arranged above the rotating box 300. An annular platform can be provided on the inner wall of the powder storage box 100, and the reinforcing ring 5001 is placed on the annular platform. The top cover 200 is located above the reinforcing ring 5001. Another function of the top cover 200 is to fix the fixed arm 500 in the powder storage box 100 to prevent the fixed arm 500 from moving axially along the powder storage box 100.

[0120] The baffle is located within the rotary box 300 and includes two side panels 5003 and a bottom panel 5004. The two side panels 5003 can be symmetrically arranged. The tops of the two side panels 5003 are respectively connected to the reinforcing ring 5001, and the bottoms of the two side panels 5003 are respectively connected to the two ends of the bottom panel 5004. The bottom panel 5004 is located directly above the powder discharge port 1001, and the lower surface of the bottom panel 5004 can fit the upper surface of the conical boss 3004 to scrape off excess powder from the top surface of the conical boss 3004, thereby quantifying the powder in the metering port 3001. This allows the metering port 3001 to input a certain amount of powder into the powder discharge port 1001, and the powder discharge from the powder discharge port 1001 is stable.

[0121] A flow-disrupting structure 5002 is provided on the upper surface of the base plate 5004 to agitate the powder within the rotating box 300 as it rotates. Under the action of the flow-disrupting structure 5002 on the fixed arm 500, the powder tumbles up and down within the rotating box 300, thereby preventing the powder from clumping and accumulating. Furthermore, the lower surface of the base plate 5004 can fit against the upper surface of the conical boss 3004 to scrape off excess powder from the top surface of the conical boss 3004, allowing the metering port 3001 to dispense a fixed amount of powder into the lower powder port 1001.

[0122] In one embodiment of the present application, the spoiler structure 5002 is a Z-shaped baffle, both ends of which are connected to the two side panels 5003 respectively, and the Z-shaped baffle is erected on the upper surface of the bottom plate 5004.

[0123] When the conical boss 3004 rotates to the bottom of the Z-shaped baffle, the powder rolls up and down in the rotating box 300 under the action of the Z-shaped baffle and is filled into the metering port 3001. As the rotating box 300 rotates, the Z-shaped baffle pushes and disturbs the powder in the rotating box 300, causing the powder to roll up and down in the rotating box 300. In addition to preventing powder agglomeration, it also allows the rolling powder to be better filled into the metering port 3001, further ensuring that the metering port 3001 of the powder dispensing device dispensing powder in a quantitative manner.

[0124] In one embodiment of the present application, again in conjunction with Figure 10, the fixed arm 500 also includes a scraper film 5005, and the scraper film 5005 is made of a deformable material, so that the scraper film 5005 has flexibility. The top of the scraper film 5005 is connected to the lower plate surface of the bottom plate 5004, and the bottom of the scraper film 5005 is in contact with the upper surface of the bottom of the rotating box 300. In the process before the conical boss 3004 rotates from other positions to the bottom of the scraper film 5005, the scraper film 5005 is blocked by the conical boss 3004 and deformed with a gradually increasing inclination. The bottom of the scraper film 5005 is transformed from being in contact with the upper surface of the bottom of the rotating box 300 to being in contact with the inclined surface 3005 of the conical boss 3004 and then to being in contact with the top surface of the conical boss 3004; when the metering port 3001 on the conical boss 3004 rotates and moves to When the powder scraping film 5005 is directly below the dosing port 3001, the force exerted by the powder in the dosing port 3001 on the powder scraping film 5005 is almost negligible, and the powder scraping film 5005 returns to the state before the tilting deformation occurs, and then pushes the powder in the dosing port 3001 out of the dosing port 3001, that is, pushes the quantitative powder in the dosing port 3001 to the powder discharge port 1001, and then flows out of the powder discharge device through the powder outlet 4002 located below the powder discharge port 1001, thus completing the quantitative powder discharge in sequence. As the rotary box 300 continues to rotate, the powder scraping film 5005 tilts and deforms again, until the bottom of the powder scraping film 5005 again adheres to the upper surface of the rotary box 300 box bottom. The powder scraping film 5005 can push the powder in the dosing port 3001 to the powder discharge port 1001 and the powder outlet 4002 through its deformation.

[0125] Because the powder scraping film 5005 is soft, when the rotating box 300 rotates and passes between the fixed arm 500 and the powder discharge port 1001, the powder scraping film 5005 pushes the powder carried by the quantitative port 3001 of the conical boss 3004 to the powder discharge port 1001, thereby achieving the effect of quantitative powder discharge.

[0126] In one embodiment of the present application, the reinforcing ring 5001 is detachably connected to the inner wall of the powder storage box 100. A protrusion or groove is provided on the reinforcing ring 5001, and a groove or protrusion is provided on the inner wall of the powder storage box 100. The protrusion cooperates with the groove to achieve a detachable connection between the reinforcing ring 5001 and the inner wall of the powder storage box 100. The groove can be designed as an annular groove, and the protrusion can also be designed as an annular protrusion. The detachable connection between the reinforcing ring 5001 and the powder storage box 100 enables quick disassembly and assembly of the fixed arm 500 and the powder storage box 100, improving the efficiency of disassembly and assembly of the powder discharge device when it needs to be cleaned or cleared.

[0127] In one embodiment of the present application, again in conjunction with Figures 3 and 5, the powder unloading device also includes a rotating head 600, which is located below the baffle 400. To be precise, the rotating head 600 is located below the boss at the center of the baffle 400. The power output end of the rotating head 600 is connected to the rotating box 300 to drive the rotating box 300 and the baffle 400 to rotate. Specifically, an annular groove can be provided on the rotating head 600, and an annular buckle that is connected to the annular groove is provided on the protrusion 3002. The annular buckle cooperates with the annular groove to achieve a detachable connection between the rotating head 600 and the rotating box 300. As a power element, the rotating head 600 can drive the synchronous rotation of the baffle 400 and the rotating box 300, thereby realizing the quantitative unloading of powder by the powder unloading device.

[0128] In one embodiment of the present application, a rubber annular sealing ring 700 is provided between the top cover 200 and the powder storage box 100. The provision of the sealing ring 700 can achieve a sealing effect on the top of the powder feeding device, preventing moisture in the air from entering the powder feeding device and causing powder agglomeration in the powder feeding device, thereby affecting powder feeding.

[0129] During use, the machine body 1 can be provided with a feeding seat, and the powder discharge device 2 can be installed on the feeding seat and be detachable. The feeding seat is provided with a first motor connected to a controller, and the output end of the first motor can be transmission-connected to the gear plate and the rotating box 300 via a rotating head 600. When the powder brewing machine is in operation, the controller can control the first motor to drive the gear plate and the rotating box 300 to rotate, so that the metering port 3001 on the rotating box 300 can discharge a fixed amount of powder into the powder discharge port 1001. The first motor can control the rotation frequency of the gear plate and the rotating box 300 through Hall effect sensing and an electronic control program, thereby achieving quantitative control of the powder discharged into the powder discharge port 1001. After the metering port 3001 of the rotating box 300 and the powder outlet 4002 on the baffle plate 400 are offset from the powder outlet 1001 of the powder storage box 100, the first motor stops driving, so that the bottom plane of the rotating box 300 and the upper plane of the baffle plate respectively block the powder outlet 1001 of the powder storage box 100, preventing water vapor from entering the powder storage box 100, and at the same time preventing small animals such as cockroaches and ants from entering the powder outlet device through the powder outlet 1001 and causing contamination of the powder brewing machine.

[0130] 14 and 15 , the milk shaking mechanism includes a milk shaking device 10 and a weighing device 20 .

[0131] The shaking device 10 can be placed on a container 30, which can be shaken to evenly mix the contents. Specifically, the lower half of the container 30 can be placed inside the shaking device 10. When milk powder and water are placed in the container 30 and need to be evenly mixed, the shaking device 10 can be rotated to thoroughly mix the milk powder and water in the container 30. The powder includes, but is not limited to, milk powder, coffee powder, juice powder, etc. In this embodiment, the following description uses milk powder as an example.

[0132] As shown in FIG16 , the weighing device 20 includes a weighing plate 201 , a bracket and a motor 202 , wherein:

[0133] The weighing pan 201 can be disc-shaped, and the upper surface of the weighing pan 201 can be flat. The liquid dilution device 10 can be placed on the weighing pan 201, and the weighing pan 201 is used to support the liquid dilution device 10. The weighing pan 201 can be detachably connected to the liquid dilution device 10, so that the liquid dilution device 10 can be quickly removed from the weighing pan 201 for cleaning and quickly reattached to the weighing pan 201 after cleaning.

[0134] In addition, a receiving cavity is formed at the bottom of the weighing pan 201 so that the bracket can be at least partially received in the receiving cavity, and the receiving cavity can protect the bracket.

[0135] The bracket includes a motor bracket 203 and a transmission bracket 204, wherein the motor bracket 203 and the transmission bracket 204 are connected via a ball bearing 205. The weighing plate 201 is detachably mounted on the transmission bracket 204 so that when the transmission bracket 204 rotates, the weighing plate 201 can rotate synchronously with the transmission bracket 204. For example, the weighing plate 201 can be fixed to the transmission bracket 204 by a clamping method. The motor 202 is mounted on the motor bracket 203, and the output shaft of the motor 202 is connected to the transmission bracket 204. Specifically, the end of the output shaft of the motor 202 can pass through the motor bracket 203 and connect to the bottom center of the transmission bracket 204. The motor 202 is used to drive the transmission bracket 204 and the weighing plate 201 to rotate synchronously, thereby driving the liquid shaking device 10 placed on the weighing plate 201 to rotate, thereby achieving thorough mixing and shaking of the milk powder and water in the container 30 placed on the liquid shaking device 10.

[0136] In the embodiment of the present invention, structural components such as a motor 202, a transmission bracket 204 and a ball bearing 205 are arranged in a weighing device 20, and a liquid shaking device 10 is arranged on a weighing plate 201 of the weighing device 20, so that the transmission bracket 204 and the weighing plate 201 are driven to rotate by the motor 202, thereby driving the liquid shaking device 10 placed on the weighing plate 201 to rotate.

[0137] By arranging the ball bearing 205 in the weighing device 20 , it is possible to prevent the grease in the ball bearing 205 from leaking into the liquid shaking device 10 , thereby preventing the liquid shaking device 10 from being difficult to clean.

[0138] In some embodiments, referring to FIG. 4 , the liquid shaking device 10 includes a liquid shaking base 101 , a lifting base 102 , a liquid shaking base support 103 , a container fixing frame 104 and a stabilizing cover 105 .

[0139] 18 , the liquid shaking base 101 has a storage space capable of accommodating the lifting base 102, so that the lifting base 102 can be installed in the liquid shaking base 101. Specifically, at least two trapezoidal slots 1011 can be provided on the inner sidewall of the storage space, with a snap-on opening 1012 formed at the upper portion of the trapezoidal slots 1011. Positioning posts 1021 are provided at the lower portion of the outer wall of the lifting base 102. For example, the positioning posts 1021 can be made of a plastic material. Each positioning post 1021 includes two semicircular cylinders spaced apart. When the lifting base 102 is installed in the liquid shaking base 101, the two semicircular cylinders can form an elastic structure, allowing the positioning post 1021 to smoothly snap into the snap-on opening 1012 and cooperate with the trapezoidal slots 1011. The positioning post 1021 can move up and down along the trapezoidal slots 1011 to adjust the height of the lifting base 102 in the liquid shaking base 101.

[0140] The liquid shaking seat bracket 103 is detachably connected to the liquid shaking seat 101 and is disposed on the weighing pan 201. For example, a buckle or groove is provided on the liquid shaking seat bracket 103, and a groove or buckle is provided on the liquid shaking seat 101, and the buckle and the groove cooperate to enable the liquid shaking seat bracket 103 to be detachably connected to the liquid shaking seat 101. The cooperation of the buckle and the groove enables the rapid disassembly and installation of the liquid shaking seat bracket 103 and the liquid shaking seat 101, facilitating the disassembly and cleaning of the liquid shaking device 10. Of course, it is understood that the liquid shaking seat bracket 103 and the liquid shaking seat 101 can also be detachably connected using other methods. This is merely an example and does not constitute a limitation on the scope of protection of the claims.

[0141] The container holder 104 is disposed within the lifting base 102. Referring to FIG19 , the container holder 104 defines a space for accommodating the container 30. The container holder 104 is provided with an elastic retaining structure for retaining the container 30 within the container holder 104. For example, the elastic retaining structure may be a plurality of elastic claws 1041. One end of each elastic claw 1041 is connected to the inner wall of the container holder 104, and the other end of each elastic claw 1041 extends downwardly and obliquely toward the inside of the container holder 104. The other ends of each elastic claw 1041 collectively form a circular hole through which the bottom of the container 30 can pass. The elastic claws 1041 elastically secure the container 30, thereby firmly securing the container 30 within the container holder 104.

[0142] The stabilizing cover 105 with elastic deformation performance is fixed on the top of the lifting base 102 and the outer wall of the container 30 to stabilize the container 30. The stabilizing cover 105 is fixed to the edge position of the top of the lifting base 102 and can be easily assembled and disassembled.

[0143] The container holder 104 and the stabilizing cover 105 secure the container 30, improving its stability within the dilution device 10. The dilution base bracket 103 of the dilution device 10 is mounted on the weighing pan 201, allowing the dilution device 10 to be removed from the weighing pan 201 for cleaning or quickly reinstalled as needed. The stabilizing cover 105 is secured to the top of the lifting base 102, making it easy to remove and clean the interior of the dilution device 10.

[0144] In one embodiment of the present application, referring to Figure 20 , a through-hole 1051 is formed in the center of the stabilizing cover 105. The diameter of the through-hole 1051 is approximately 50 mm, slightly smaller than the outer diameter of the container 30. The bottom end of the container 30 passes through the through-hole 1051 and the container holder 104 and is then placed within the lifting base 102. The stabilizing cover 105 further secures the container 30 via the through-hole 1051, preventing the container 30 from shaking within the lifting base 102 and affecting the milk shaking process of the milk shaking device 10.

[0145] In one embodiment of the present application, the stabilizing cover 105 includes an annular cover body 1052 and a deformable stabilizing tab 1053 extending from the cover body 1052 toward the center of the cover 105. The distal end of the stabilizing tab 1053 forms a through-hole 1051. An annular groove is formed at the bottom of the cover body 1052, which is secured to the top edge of the lift base 102. The deformable stabilizing tab 1053 secures the container 30 passing through the through-hole 1051, further preventing the container 30 from shaking within the lift base 102 and ensuring that the liquid shaking device 10 fully mixes and evenly shakes the milk powder and water in the container 30.

[0146] In one embodiment of the present application, the stabilizing cover 105 is made of silicone and includes at least two stabilizing sheets 1053. When the container 30 is not placed on the dilution device 10, each stabilizing sheet 1053 extends horizontally toward the center of the stabilizing cover 105, with a 2 mm spacing between adjacent stabilizing sheets 1053. When the container 30 is placed in the dilution device 10, because the diameter of the through hole 1051 is slightly smaller than the outer diameter of the container 30, the container 30 passes through the through hole 1051 of the stabilizing cover 105, pressing the end of the stabilizing sheet 1053 near the center of the stabilizing cover 105 downward. This end of the stabilizing sheet 1053 adheres tightly to the outer wall of the container 30, thereby securing the container 30. For containers 30 of varying sizes, even those with outer diameters slightly larger than the diameter of the through hole 1051, the stabilizing sheet 1053 can deform to adhere tightly to the outer wall of the container 30, ensuring compatibility with containers 30 of various sizes.

[0147] In one embodiment of the present application, as shown in FIG21 , the liquid-shaking support 103 is cylindrical, with at least two elongated grooves 1031 disposed on its inner wall. The lengths of the elongated grooves 1031 are parallel to the axial direction of the liquid-shaking support 103. At least two protrusions 2011 are disposed on the outer circumference of the weighing pan 201. The number and arrangement of the protrusions 2011 correspond to the number and arrangement of the elongated grooves 1031. The protrusions 2011 cooperate with the elongated grooves 1031 to provide a detachable connection between the liquid-shaking support 103 and the weighing pan 201. When the liquid shaking seat bracket 103 needs to be installed on the weighing pan 201, the ridges 2011 can be aligned with the long grooves 1031, and then the weighing pan 201 can be pressed downward from the top until the ridges 2011 are locked into the long grooves 1031. When the liquid shaking seat bracket 103 needs to be removed from the weighing pan 201, the liquid shaking device 10 can be pulled upward until the ridges 2011 are disengaged from the long grooves 1031. The cooperation between the ridges 2011 and the long grooves 1031 enables the liquid shaking seat bracket 103 and the weighing pan 201 to be quickly disassembled and assembled, thereby facilitating the rapid removal of the liquid shaking device 10 from the weighing device 20 for cleaning and the rapid assembly of the liquid shaking device 10 to the weighing device 20, thereby improving the user experience when cleaning the liquid shaking device 10.

[0148] In one embodiment of the present application, referring again to FIG. 16 , the weighing device 20 further includes a fixed base 206. The motor 202 and the bracket are both disposed within the fixed base 206. The weighing pan 201 is spaced apart from the fixed base 206, and the weighing pan 201 is positioned above the fixed base 206. A load-bearing plate 207 and a gravity sensor 208 may also be disposed within the fixed base 206. The load-bearing plate 207 may be connected to the motor bracket 203 to support the motor 202 and the motor bracket 203. The gravity sensor 208 is used to sense the overall weight of the shaking device 10 disposed on the weighing pan 201. The gravity sensor 208 may be connected to a controller of a milk preparation machine including the shaking mechanism via a communication line to transmit signals sensed by the gravity sensor 208 to the controller. The controller may then convert the received signals into display signals. For example, the display signals may directly display the weight of the milk powder and water in the container 30, allowing the user to see the weight of the milk powder and water in the container 30 and thereby control whether to continue adding milk powder and water to the container 30. The fixing base 206 can protect the motor 202 and the bracket installed therein; and there is a distance between the weighing plate 201 and the fixing base 206 so that the fixing base 206 does not affect the rotation of the weighing plate 201.

[0149] As shown in FIG22 , another embodiment of the present application also provides a beverage brewing method, which is applied to the powder brewing machine as described in any of the above embodiments, and the method includes:

[0150] S1: Obtaining water-powder ratio information and brewing total amount information, wherein the brewing total amount information is the total amount of the beverage brewed this time;

[0151] S2: Determine the target amount of water and target amount of powder required for brewing the beverage based on the water-powder ratio information and the brewing total amount information;

[0152] S3: controlling the hot water supply device to obtain the target amount of brewing water from the water tank and heating the brewing water;

[0153] When it is determined based on the feedback information of the weighing device that the container for holding the beverage is located on the liquid shaking device, S4: the powder feeding device, the hot water supply device, and the liquid shaking mechanism are controlled to operate so as to match the output of the target amount of powder and the target amount of hot water into the container, and the container is rotated to mix the powder and the hot water evenly to complete the beverage brewing.

[0154] For example, a powder brewing machine has a DIY input interface for users to input brewing information, including water-powder ratio information, brewing total amount information, etc. The water-powder ratio information can be obtained from the packaging of the brewing product. Taking milk powder as an example, assuming a certain brand of milk powder, the packaging instructions indicate that 29 grams of milk powder should be added for every 200ml of water, the user needs to enter 200ml / 29g in the corresponding position of the machine's DIY interface; or, assuming a certain brand of milk powder, the packaging instructions indicate that 8.6 grams of milk powder should be added for every 2oz of water, the user needs to enter 2oz / 8.6g in the corresponding position of the machine's DIY interface. After the user obtains the water-powder ratio information, he will enter the above information through the input interface. When the powder brewing machine obtains the water-powder ratio input by the user, it will perform calculations based on the preset program. The calculation process includes:

[0155] The amount of powder required per milliliter of water = the amount of powder input by DIY ÷ the amount of water input by DIY

[0156] The conversion formula between ounces (oz) and milliliters (ml) is as follows:

[0157] 1 ounce (oz) = 29.57 milliliters (ml)

[0158] That is, the brewing machine will automatically analyze and identify the information input. When it determines that the capacity unit needs to be converted, it will automatically convert the capacity unit. Then, the subsequent target powder amount and target water amount will be determined based on the converted water-powder ratio. In this way, the powder brewing machine can be suitable for users in different countries and meet the brewing needs of different users.

[0159] Specifically, the method further includes:

[0160] S5: Obtaining information about the type of beverage to be brewed;

[0161] S6: Determine the brewing water temperature based on the beverage type information;

[0162] The step of heating the brewing water comprises:

[0163] The hot water supply device is controlled based on the brewing water temperature to heat the brewing water.

[0164] For example, the user inputs beverage type information, such as brewing formula milk, brewing coffee, etc. After the powder brewing machine obtains the brewing type information, it can determine the heating temperature of the brewing water. For example, when the brewing type is formula milk, the brewing water temperature can be determined to be 45°, or 45°-50°. When it is brewing coffee, the brewing water temperature can be determined to be 100°, or 95°-100°, etc.

[0165] Furthermore, the method further comprises:

[0166] S7: determining whether the container is located on the liquid shaking device based on the first weight information fed back by the weighing device;

[0167] S8: When it is determined that the container is located on the liquid shaking device, the weighing device is tare-processed.

[0168] That is, after receiving the first weight information fed back by the weighing device, the brewing machine will determine whether a container for beverages, such as a milk bottle, juice cup, etc., has been placed and fixed on the liquid shaking device based on the first weight information. If it is determined that the container has been placed, the brewing machine will automatically control the weighing device to perform a peeling operation to prepare for the subsequent weighing of brewing water and powder.

[0169] When controlling the powder feeding device, hot water supply device and liquid shaking mechanism to operate, it includes:

[0170] S9: Determine multiple water outputs based on a preset proportional coefficient, and the sum of the multiple water outputs is the target water volume;

[0171] S10: controlling the hot water supply device to output a first amount of hot water to the container;

[0172] S11: controlling the liquid shaking device to continuously rotate the container;

[0173] S12: Controlling the powder feeding device to output a target amount of powder into the container;

[0174] S13: controlling the hot water supply device to output a second amount of hot water to the container;

[0175] S14: Controlling the liquid shaking device to stop rotating;

[0176] S15: Control the hot water supply device to output a third amount of hot water to the container.

[0177] The method further comprises:

[0178] S16: obtaining second weight information of the container fed back by the weighing device, and determining whether the hot water supply device has completed outputting the first amount of hot water based on the second weight information; if so, controlling the hot water supply device to stop outputting hot water;

[0179] S17: obtaining third weight information of the container fed back by the weighing device, and determining whether the powder feeding device has completed outputting the target amount of powder based on the third weight information; if so, controlling the powder feeding device to stop outputting powder;

[0180] S18: obtaining fourth weight information of the container fed back by the weighing device, and determining whether the hot water supply device has completed outputting the second amount of hot water based on the fourth weight information; if so, controlling the hot water supply device to stop outputting hot water;

[0181] S19: obtaining fifth weight information of the container fed back by the weighing device, and determining whether the hot water supply device has completed outputting the third amount of hot water based on the fifth weight information; if so, controlling the hot water supply device to stop outputting hot water.

[0182] For example, when preparing formula:

[0183] Users need to obtain the brewing ratio, i.e. the water-to-powder ratio information, based on the packaging label of the brewing product;

[0184] The obtained water-powder ratio information and the total brewing amount information, that is, the required brewing volume, are input into the brewing machine through the machine's DIY interface. The brewing machine can automatically calculate the current required amount of milk powder and brewing water according to the water-powder ratio information and the total brewing amount information, that is, the target powder amount and target water amount;

[0185] The user can also enter information about the brewing type, such as brewing formula;

[0186] In response to the user's input, the powder brewing machine determines the target temperature and controls the hot water supply device to obtain a corresponding amount of brewing water from the water tank according to the target water volume, and then heats the brewing water of the target water volume until it reaches the target temperature;

[0187] Determine whether the container has been placed on the liquid shaking device through the weighing information fed back by the weighing device, and if so, control the weighing device to tare;

[0188] The hot water supply device is controlled to fill the container with water for the first time. The water filling amount can be determined according to the default configuration, 50% of the user-set capacity, or a user-set custom capacity. The water filling process is monitored by the weighing device based on real-time feedback of weighing information from the weighing device. When the water filling amount for the first time is determined to have reached the required amount based on the feedback of the weighing information of the container, the hot water supply device is controlled to stop discharging water.

[0189] The liquid shaking device is controlled to rotate the container. The speed and direction of rotation during the rotation process can be fixed or variable. For example, the speed is slow in the initial stage, slow in the powder addition stage, and fast in the remaining stages. The rotation direction can be forward first, then reverse, or alternate, etc., which can be determined in detail to better simulate the human hand shaking action and improve the brewing effect.

[0190] The powder feeding device is controlled to discharge powder, and the weight information fed back by the weighing device is used to monitor the powder output. The powder output this time is 100%, that is, the target amount of powder is output at one time. When the powder injection amount reaches the requirement based on the weight information, the powder feeding device is controlled to stop running;

[0191] The hot water supply device is controlled to inject water into the container for the second time. The water injection amount can be, but is not limited to, 30% of the user-set capacity. The water injection process is still monitored by the weight information fed back by the weighing device. When the water injection amount requirement is reached, the water supply is stopped and the milk shaking operation is continued. Once the milk shaking operation is started, it will not stop. Even during the powder addition and water injection, the container will not stop rotating, so as to achieve the effect of adding powder and water while shaking the milk. Until the preset milk shaking time expires, the liquid shaking device is controlled to stop operating;

[0192] The hot water supply device is controlled to inject water into the container for the third time. The water injection amount is determined to be 20% of the user-set capacity. The water injection process is still monitored by the weight information fed back by the weighing device. When it is determined based on the feedback weight information that the water injection amount has reached the requirement, the hot water supply device is controlled to stop discharging water.

[0193] At this point, the entire milk preparation process is completed.

[0194] In the above process, whether it is adding water or powder, the weighing device weighs the container in real time and feeds back the weight information. The controller can accurately monitor the amount of powder and the amount of water added each time based on the fed-back weight information to avoid errors, ensure that the ratio of the brewed beverage is accurate and meets the ratio on the powder packaging, and will not be too thick or too thin, so as to achieve automatic brewing of beverages with both nutrition and taste.
