Description

A beverage mixing machine Technical Field

[0001] This invention relates to the field of beverage preparation equipment technology, specifically to a beverage mixing machine. Background Technology

[0002] Newborns typically need to be fed multiple times at night, which often requires preparing formula. This process involves putting a certain amount of formula into a bottle, adding hot water, shaking repeatedly to mix the formula and water, and finally feeding it to the baby. For mothers who are already sleep-deprived, this series of actions is very tedious and time-consuming. Sometimes, to prepare formula for the baby, mothers need to get out of bed, and after finishing all this, it's difficult to fall back asleep. Therefore, using a formula preparer is essential.

[0003] Currently, there are milk powder mixing machines on the market, which are equipped with multiple independent milk powder compartments. Each milk powder compartment is used to hold a fixed amount of milk powder, so as to realize multiple and quantitative milk powder mixing.

[0004] A search revealed Chinese invention patent CN218552085U, which discloses a milk powder preparer. Milk powder is pre-added into different chambers within a powder container assembly. A drive mechanism rotates the inner housing within the outer shell, causing a protruding protrusion to open the powder outlet. When the outlet aligns with the exit point, the milk powder placed within the chambers enters the bottle through the outlet and exit point, completing the dispensing of the correct amount of milk powder. A water pump then introduces water from the tank into the bottle, thus automatically preparing the milk powder.

[0005] However, the above-mentioned milk powder mixing machine has the following problems during use:

[0006] 1. Often, not all the milk powder in the chamber can fall into the bottle, and some milk powder remains on the inner wall of the chamber, resulting in waste of milk powder and insufficient milk powder for a single feeding.

[0007] 2. Residual milk powder may become damp, clump, or even spoil. During use, if the amount of milk powder is insufficient at one time, the cap may be opened frequently to add more milk powder, which is more likely to cause the milk powder to become damp, clump, or even spoil, affecting the taste of the milk powder and even endangering the baby's health.

[0008] 3. Existing beverage mixing machines lack bottle clamping and bottle position adjustment mechanisms, making it impossible to adjust the height of the bottle. As the milk powder falls, it easily spills out of the bottle, resulting in waste. They are also not suitable for various bottle sizes, and it is inconvenient to pick up and put down the bottle.

[0009] 4. The milk powder in each independent chamber needs to fall into the container through a common outlet. Milk powder is easy to get stuck at the common outlet, which is not easy to clean. The milk powder residue will get damp, clump, or even spoil.

[0010] 5. It adopts a double-layer structure, with an additional bottom cover, making the structure complex;

[0011] 6. The chamber and cover are not transparent, so the amount of milk powder in the hopper and the milk powder feeding situation cannot be observed from the outside. If powder jamming or accumulation occurs, the milk powder ratio and concentration will not meet the standards. In the long run, this will lead to malnutrition in infants and affect their growth. Summary of the Invention

[0012] The purpose of this invention is to provide a beverage mixing machine that solves the problem in the prior art where the height of the mixing vessel is not adjustable due to the lack of a height adjustment mechanism, resulting in the powder falling outside the bottle and causing waste.

[0013] To achieve the above objectives, the present invention provides a beverage mixing machine, comprising a machine body and the following installed on the machine body: a powder dispensing device for dispensing powder into a mixing vessel; a powder mixing device, including a mixing device for mixing the powder and water in the mixing vessel and a height adjusting device for adjusting the height of the mixing vessel; and a water storage container connected to a water outlet pipe for rinsing water into the mixing vessel.

[0014] This beverage mixing machine automatically dispenses mixing powder and water into the mixing container, and automatically mixes the powder and water, greatly simplifying the mixing process and bringing great convenience to users. At the same time, it is also equipped with a height adjustment device to adjust the height of the mixing container, preventing powder from falling out of the bottle and causing waste, and it can be used with mixing containers of various sizes.

[0015] Preferably, the powder dispensing device includes several hoppers disposed on the machine body. Each hopper has an inlet at the top for loading powder into the hopper, and a first discharge port at the bottom for allowing the powder, such as milk powder, to fall into the mixing container. A closable door is installed at the first discharge port of each hopper, and the machine body has an opening device for opening the door. The hoppers are individually configured, each with a first discharge port at its bottom. The powder falls directly into the mixing container through the first discharge port, greatly reducing the possibility of clogging and preventing powder accumulation. Each independent hopper can be cleaned separately, ensuring convenience and hygiene.

[0016] When you need to prepare a beverage, activate the door opening mechanism. The door opens, and the powder falls into the preparation container, such as a baby bottle. Each compartment contains an individual amount of powder, making it easy to control the amount prepared each time and to easily check for any powder residue, preventing waste. Since the powder can be pre-measured in the compartments, users don't need to retrieve powder on the fly or pre-fill the compartments, offering great convenience. Multiple compartments can be placed on the platform, allowing for pre-measured powder preparation for multiple servings, making it particularly suitable for scenarios where multiple batches of formula need to be prepared at night.

[0017] Preferably, the powder dispensing device includes a platform rotatably mounted on the machine body, two or more hoppers located on the platform and arranged around the rotation center of the platform, a platform drive mechanism connected to the bottom of the platform for driving the platform to rotate, the platform drive mechanism being mounted on the machine body, and a hopper mounting part on the platform corresponding to the hopper. The hopper is located at the hopper mounting part. When the platform drives the hopper to rotate to a preset position above the mixing container, the door opening device opens the hopper door of the hopper that has reached the preset position, and the powder falls into the mixing container through the first discharge port. The platform drives the hopper to rotate to the preset position above the mixing container, the door opening device automatically opens the hopper door, and the powder in the hopper falls into the mixing container to achieve powder dispensing. After completion, the platform drives the hopper away from the mixing container. The structure is simple and easy to use. The powder dispensing device can precisely control the opening of the hopper door when it is directly above the mixing vessel, preventing the powder from spilling outside the mixing vessel and causing waste.

[0018] Preferably, the top of the machine body is equipped with a machine compartment, and the machine compartment is equipped with a machine cover. The machine compartment is used to house the hopper, the platform, and the platform-driven mechanism. The machine compartment and the machine cover provide enclosed storage for the hopper, the platform, and the platform-driven mechanism, protecting the relevant components, preventing dust from falling into the hopper, ensuring cleanliness and hygiene. At the same time, the machine compartment and the machine cover can be designed in various shapes or styles to achieve an aesthetically pleasing effect.

[0019] Preferably, the hopper is fixedly mounted on the platform as an integrated unit. This integrated mounting allows for the simultaneous removal of both the hopper and the platform for cleaning or adding powder, making the process convenient, quick, and easy to assemble and disassemble.

[0020] Preferably, the hoppers are detachably mounted on the platform. This detachable mounting allows each hopper to be individually removed for cleaning or powder replenishment, making assembly and disassembly convenient and quick.

[0021] Preferably, the powder dispensing device includes a storage bin located on the top of the machine body, a powder dispensing mechanism inside the storage bin, and a second dispensing port at the bottom of the storage bin corresponding to the mixing vessel. The powder dispensing mechanism controls the amount of powder to be dispensed into the mixing vessel through the second dispensing port. This design integrates the storage bin for storing powder, which can then be dispensed directly into the mixing vessel through the second dispensing port, resulting in a simple structure and convenient operation.

[0022] Preferably, a hopper is integrally or detachably installed at the second discharge port, with the hopper directly opposite the mixing vessel. The powder dispensing mechanism controls the amount of powder to fall into the hopper through the second discharge port. This design allows the storage hopper to hold the powder, which first falls into the hopper through the second discharge port, then into the mixing vessel. The hopper assists in the powder's flow into the mixing vessel, preventing it from drifting outside during its descent. The design is simple and easy to use.

[0023] Preferably, the powder dispensing mechanism includes a rotating powder dispensing part rotatably installed in the storage silo. The rotating powder dispensing part contains powder, and the bottom of the rotating powder dispensing part has a discharge port corresponding to the second discharge port. When the second discharge port or the silo rotates to a preset position, the powder in the storage silo falls into the mixing vessel or silo through the discharge port and the second discharge port.

[0024] Preferably, a sealing cover is provided at the feed inlet, and the powder in the hopper is sealed and preserved through the sealing cover and the hopper door to prevent the powder from deteriorating due to moisture.

[0025] Preferably, the hopper door is installed integrally or detachably at the first material inlet. The hopper door remains closed until the hopper reaches the preset position. When the hopper reaches the preset position, the door opening device opens the hopper door by directly acting on the hopper door or by acting on the hopper door locking device.

[0026] Preferably, when the door opening device opens the hopper door by directly acting on the hopper door, the hopper door is set at the first material inlet by horizontal swinging, horizontal sliding or hinge. At this time, the hopper door only opens when the hopper reaches the preset position and remains closed when it moves away from the preset position. This can prevent residual powder in the hopper from spilling, keep the device clean and tidy, reduce the number of times the user cleans, and prevent residual powder in the hopper from getting damp, affecting the taste and quality of the subsequent brewing of new powder.

[0027] When the door opening device opens the bin door by acting on the bin door locking device, the bin door is hinged at the first discharge port and remains free to open and close.

[0028] Preferably, the silo door locking device includes a swing arm hinged to the silo, with the hinge point of the swing arm located in its middle. The lower end of the swing arm is provided with a hook for hooking the free end of the silo door to keep the silo door closed. A first elastic element is provided between the swing arm and the side wall of the silo to maintain the hook holding the free end of the silo door. When the upper end of the swing arm is pressed, the hook disengages from the silo door, thereby opening the silo door. The structure is simple and easy to use.

[0029] Preferably, the silo door locking device includes a swing arm hinged to the silo, with the hinge point of the swing arm located at its top. The lower end of the swing arm is provided with a hook for hooking the free end of the silo door to keep the silo door closed. A first elastic element is provided between the swing arm and the side wall of the silo to maintain the hook holding the free end of the silo door. When the middle of the swing arm is pressed, the hook disengages from the silo door, thereby opening the silo door. The structure is simple and easy to use.

[0030] Preferably, the silo door locking device includes a push block slidably disposed on the silo. The bottom end of the push block is provided with a hook for hooking the free end of the silo door to keep the silo door in a closed state. A first elastic element is provided between the push block and the silo to maintain the hook hooking the free end of the silo door. When the top of the push block is pressed, the push block drives the hook to move down and disengage the hook from the silo door, thereby opening the silo door. The structure is simple and easy to use.

[0031] Preferably, the door opening device includes a push block mounted on the machine body. When the platform rotates the hopper to a preset position above the mixing vessel, the push block presses against the hopper door locking device or the hopper door, causing the free end of the hopper door to disengage and thus opening the hopper door. When the hopper rotates with the platform to reach the set position, the push block automatically presses against the hopper door locking device or the hopper door. The advantage of this structure is that the hopper door opens automatically when the hopper is in place, the door opening device does not require separate control, and this structure is relatively reliable.

[0032] Preferably, the door opening device includes a push rod slidably mounted on the machine body and a cam mounted on the platform. The cam rotates with the platform, with its larger end acting on the inner end of the push rod, and the outer end of the push rod facing the swing arm. When the platform drives the hopper to rotate to a preset position above the mixing vessel, the cam pushes the outer end of the push rod to press against the hopper door locking device or the hopper door, causing the free end of the hopper door to disengage and thus opening the hopper door. When the hopper rotates with the platform to reach the set position, the cam pushes the outer end of the push rod to press against the hopper door locking device or the hopper door. The advantage of this structure is that the hopper door opens automatically when the hopper is in position, the door opening device does not require separate control, and this structure is relatively reliable.

[0033] Preferably, the door opening device includes a power component mounted on the machine body capable of outputting linear motion. When the platform rotates the hopper to a preset position above the mixing vessel, the power output end of the power component extends out to press against the door locking device or the door, causing the free end of the door to disengage and thus opening the door. When the hopper rotates with the platform to reach the set position, the power output end of the power component extends out to press against the door locking device or the door. The advantage of this structure is that the door opens automatically when the hopper is in position, the door opening device does not require separate control, and the power component is easy to control and install.

[0034] Preferably, when the opening device directly acts on the bin door to open it, the opening device includes a drive motor mounted on the bin for driving the bin door to open and close. When the bin rotates with the platform to the set position, the opening device directly acts on the bin door to open it. The advantage of this structure is that the bin door opens automatically when the bin is in place, reducing the number of parts used, simplifying the structure, making maintenance convenient, and increasing efficiency.

[0035] Preferably, the machine body is equipped with a water outlet pipe for connection to a water supply device. The water outlet pipe has a drain port for dispensing water into the mixing container. The drain port is located below the powder dispensing device. The drain port is mounted on the machine body in a manner that allows it to swing left and right. The machine body is equipped with a first power device for driving the drain port to swing. After the powder falls into the mixing container, the drain port swings to one side so that the drain port is directly above the mixing container for dispensing water. After dispensing water, the drain port moves away from the first discharge port as the drain port continues to swing to one side or the other. When the drain port swings to a position below the first discharge port, it can dispense water into the mixing container. When the drain port swings away from the first discharge port, it avoids obstructing the falling powder and also prevents the powder from falling into the drain port.

[0036] Preferably, the machine body is equipped with a water outlet pipe for connection to a water supply device. The water outlet pipe has a drain port for dispensing water into the mixing container. The drain port is located below the powder dispensing device. The drain port is slidably connected to the machine body in a retractable manner. The machine body is equipped with a second power device for driving the extension and retraction of the drain port. When the powder falls into the mixing container, the drain port extends forward so that the drain port is directly above the mixing container for dispensing water. After dispensing, the drain port retracts, and the drain port moves to its initial position. When the drain port extends, it can dispense water into the mixing container. When the drain port retracts, it avoids obstructing the falling powder and also prevents the powder from falling onto the drain port.

[0037] Preferably, a notch is provided between adjacent hoppers, and a water outlet pipe is installed on the machine body for connection to a water supply device. The water outlet pipe has a drain port for discharging water into the mixing container. The drain pipe section containing the drain port is located above the hopper. When the notch moves above the mixing container, the drain port discharges water, which enters the mixing container through the notch. With this structure, the powder addition and the discharging of water into the mixing container occur sequentially and independently, without affecting each other.

[0038] Preferably, a vibration motor is installed on the hopper. The vibration motor is installed on the hopper to ensure that the powder material falls smoothly and to prevent the powder material from being difficult to slide down due to clumping, moisture or other reasons.

[0039] Preferably, the machine body is equipped with a vibration motor, which has vibration protrusions. When the platform drives the hopper to rotate to a preset position above the mixing vessel, the vibration protrusions on the vibration motor can act on the hopper to cause the powder to fall. The vibration motor is mounted on the machine body, requiring only one vibration motor, which simplifies the structure and reduces costs. At the same time, the friction between the hopper and the platform is small during vibration, which can reduce noise.

[0040] Preferably, the powder dispensing device is made entirely or partially of transparent material. By using transparent material, the amount of powder in the hopper and the powder dispensing process can be observed from the outside, allowing for timely detection of powder jams or accumulations, thereby ensuring the correct milk powder ratio and concentration.

[0041] Preferably, the mixing device includes a support base and a container holder. The container holder is used to hold the mixing container. The support base is connected to the machine body, and the container holder is movably mounted on the support base. The container holder is mounted on the support base in a manner that allows it to rotate around a vertical axis. A motor mounted on the support base is connected to the bottom of the container holder. The forward and reverse rotation of the motor can drive the container holder to rotate in both directions, thereby agitating the mixing container. This mixing device can prevent powder from adhering to the inner wall of the mixing container, and it is less likely to generate air bubbles during the mixing process, resulting in a better mixing effect.

[0042] Preferably, the vessel stand is cup-shaped, and an elastic retaining ring is installed at the rim of the vessel stand. When a brewing vessel is placed on the vessel stand, the elastic retaining ring is fitted over the brewing vessel to secure it.

[0043] Preferably, the height adjustment device includes a sliding groove on the machine body, and a sliding block on the mixing device that slides along the sliding groove. The mixing device rises and falls along the sliding groove via the sliding block. An elastic retaining ring is used to keep the mixing vessel fixed, preventing it from bumping against the vessel base, and also facilitating the removal of the mixing vessel. The mixing device automatically mixes the beverage, further freeing up hands and making it convenient to use.

[0044] Preferably, the height adjustment device includes a fixedly mounted ratchet and a corresponding stop hinged to the ratchet. The ratchet passes through the bottom of the mixing device and guides the adjustment of the mixing device's height. When the mixing device reaches the target height, the ratchet and the stop engage and lock to fix the position of the mixing device. This design allows for continuous and precise adjustment of the mixing device's height, provides a wide height adjustment range, prevents powder from falling outside the bottle during the descent process, thus avoiding powder waste, and is suitable for various sizes of mixing containers.

[0045] Preferably, the stop includes a stop body hinged to the support base, a pressing block is provided on the side of the stop body away from the ratchet, an inclined surface is provided on the side of the stop body close to the ratchet corresponding to the ratchet, and a spring is installed between the pressing block and the support base.

[0046] Preferably, the height adjustment device includes a first fixing part that is separately provided or installed on the body of the machine or on the water storage container, and a second fixing part corresponding to the first fixing part of the mixing device. When the mixing device reaches the target height, the first fixing part and the second fixing part cooperate to lock and fix the height position of the mixing device. The first fixing part and the second fixing part can be hooks or fixing blocks that cooperate with each other. The height position of the mixing device is fixed by the cooperation of the first fixing part and the second fixing part. The structure is simple and easy to use.

[0047] Preferably, the height adjustment device includes at least one second pad that is separately installed, mounted on the machine body, or mounted on the water storage container and is slidably installed on the machine body. When the mixing device reaches the target height, the at least one second pad is pulled out to the bottom of the mixing device to fix its position. The height of the mixing device is fixed by the pull-out pad, resulting in a simple structure and convenient use.

[0048] Preferably, the height adjustment device also includes a vertical cylinder mounted on the machine body and driven to rotate by a third power unit. The vertical cylinder and the mixing device are provided with engaging drive threads, and the mixing device is vertically slidably connected to the machine body. The power unit drives the vertical cylinder to rotate, and the engaging drive threads, combined with the fact that the mixing device can only slide vertically, allow the mixing device to rise and fall. The advantage of this structure is that the support base rises and falls more smoothly, and the mixing vessel can rise and fall smoothly accordingly.

[0049] Preferably, the machine body includes a base, a vertical plate connected to the base, a powder dispensing device located on top of the vertical plate, a powder mixing device located on the base in front of the vertical plate, and a storage space for accommodating a water container located on the base behind the vertical plate. The advantage of this structure lies in the integrated design of the machine body and the arrangement of its various parts, resulting in a compact and convenient beverage mixing machine.

[0050] Preferably, the water storage container has an electric heating or heat preservation function, and a water pump for drawing water from the water storage container is installed in the body or the water storage container, and the water outlet pipe is connected to the water outlet of the water pump.

[0051] The beneficial effects of this invention are as follows:

[0052] 1. It can be widely used to prepare various beverages such as milk powder, coffee, and rice noodles. It not only automatically adds powder and water to the preparation container, but also automatically mixes the powder and water, greatly simplifying the preparation process and bringing great convenience to users.

[0053] 2. It is also equipped with a vibration motor on the hopper or machine body to ensure that the powder in the hopper falls smoothly, prevent the powder from remaining in the hopper, ensure sufficient powder quantity per batch, prevent the powder from getting damp and clumping or even deteriorating, avoid powder waste, and improve the use effect.

[0054] 3. By setting up a powder mixing device, it can clamp and adjust the height of the mixing container, preventing the powder from falling outside the mixing container when falling, avoiding waste, and it can be used for mixing containers of various sizes, making it convenient to pick up and put down.

[0055] 4. By setting up multiple separate material bins, each with a discharge port at the bottom, the powder falls directly into the mixing vessel through the discharge port, greatly reducing the possibility of clogging and preventing powder accumulation. The structure is simple and easy to clean.

[0056] 5. The powder dispensing device is made of transparent material, allowing external observation of the amount of powder in the hopper and the powder dispensing process. This enables timely detection of powder jams or accumulations, ensuring that the milk powder is prepared at the correct ratio and concentration. Attached Figure Description

[0089] This invention discloses a beverage mixing machine, which automatically adds powder and water to a mixing container 31 and mixes the powder and water in the mixing container 31. It can also hold the mixing container 31, adjust the height of the mixing container 31 to prevent the powder and water from spilling, and is suitable for powders of various sizes, making it convenient for beverage mixing.

[0090] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0091] As shown in Figure 1, the beverage mixing machine disclosed in this invention includes a body 1 and components mounted on the body 1:

[0092] A powder feeding device is used to feed powder into the mixing container 31;

[0093] The powder mixing device 22 includes a mixing device for mixing the powder and water in the mixing vessel 31 and a height adjustment device for adjusting the height of the mixing vessel 31; and

[0094] The water storage container 20 is connected to a water outlet pipe 17, which is used to flush water into the rinsing vessel 31.

[0095] As shown in Figures 1 to 3, the machine body 1 includes a base 28, on which a vertical plate 29 is connected. A powder dispensing device is located on top of the vertical plate 29, and a powder mixing device 22 is located on the base 28 in front of the vertical plate 29. A storage space 30 for accommodating a water storage container 20 is provided on the base 28 behind the vertical plate 29. The powder dispensing device is used to dispense powder into the mixing container 31 and automatically dispense water. The powder mixing device 22 can both mix the powder and water and raise and lower the mixing container 31 to adjust its height.

[0096] Several hoppers are set up separately, and each hopper has a first discharge port at the bottom. The powder falls directly into the mixing vessel through the first discharge port, which greatly reduces the possibility of clogging and prevents powder from accumulating. Each independent hopper can be cleaned separately, which is convenient and hygienic.

[0097] As shown in Figures 2, 3 and 25, in an embodiment of the present invention, the powder dispensing device includes a plurality of hoppers 2 disposed on the body 1. Each hopper 2 is provided with a first discharge port 3 for discharging the powder into the mixing vessel 31. A hopper door 4 that can be opened and closed is installed at the first discharge port 3 of the hopper 2. The body 1 is provided with an opening device for opening the hopper door 4.

[0098] As shown in Figure 3, in an embodiment of the present invention, the powder dispensing device includes a platform 6 rotatably mounted on the body 1, and two or more hoppers 2 are disposed on the platform 6 and arranged around the rotation center of the platform 6. In this embodiment, each hopper 2 contains powder individually, which facilitates control of the amount of powder prepared per batch, makes it easy to observe whether there is any powder residue in the hopper 2, and prevents powder waste. Furthermore, since the powder can be pre-quantified and placed in the hopper, the user does not need to temporarily retrieve the powder or pre-place powder in the hopper, providing great convenience. Multiple hoppers 2 can be placed on the platform 6, allowing for the pre-quantification of multiple portions of powder, which is particularly suitable for applications requiring multiple batches of formula preparation at night.

[0099] Furthermore, the bottom end of the platform 6 is connected to a platform rotation mechanism 61 for driving the platform 6 to rotate. The platform rotation mechanism 61 is installed on the body 1. The platform 6 is provided with a hopper mounting part 7 corresponding to the hopper 2. The hopper 2 is located at the hopper mounting part 7. When the platform 6 drives the hopper 2 to rotate to a preset position above the mixing vessel 31 (directly above the inlet of the mixing vessel 31), the door opening device opens the hopper door 4 of the hopper 2 that has reached the preset position (directly above the inlet of the mixing vessel 31), and the powder can fall into the mixing vessel 31 through the first discharge port 3.

[0100] The machine body 1 has a machine compartment 5 on top, and a machine cover on the machine compartment 5. The machine compartment 5 is used to house the hopper 2, the platform 6, and the platform rotating mechanism 61. The hopper mounting part 7 is used to fix the hopper 2. The platform rotating mechanism 61 delivers the hopper 2 containing powder to the inlet of the mixing vessel 31 for feeding. After feeding, the platform rotating mechanism 61 carries the empty hopper 2 away from the inlet of the mixing vessel 31 for the next feeding operation. In this embodiment, the powder feeding device can precisely control the opening of the hopper door 4 when the hopper 2 is directly above the inlet of the mixing vessel 31 to prevent the powder in the hopper 2 from spilling outside the mixing vessel 31 and to prevent powder waste.

[0101] As shown in Figure 6, in an embodiment of the present invention, the powder dispensing device can also adopt the following structure: the powder dispensing device includes a storage bin 51 disposed on the top of the body 1, a powder dispensing mechanism is disposed inside the storage bin 51, and a second discharge port 52 is disposed at the bottom of the storage bin 51 corresponding to the mixing vessel 31. The powder dispensing mechanism is used to dispense a fixed amount of powder into the mixing vessel 31 through the second discharge port 52. With this design, the integrated storage bin 51 is used to store powder, and the powder can be directly dispensed into the mixing vessel 31 through the second discharge port 52, which is simple in structure and convenient to use.

[0102] In this embodiment, the powder feeding device is used in conjunction with the height adjustment device in the powder mixing device 22. The height of the mixing vessel 31 is adjusted by the height adjustment device so that the inlet of the mixing vessel 31 is closer to the second discharge port 52. This can effectively prevent the powder from falling outside the mixing vessel 31 during the falling process, thus preventing powder waste and improving the performance.

[0103] As shown in Figure 7, in an embodiment of the present invention, the powder dispensing device can also adopt the following structure: the powder dispensing device includes a storage bin 51 disposed on the top of the body 1, a powder dispensing mechanism is disposed inside the storage bin 51, and a second discharge port 52 is disposed at the bottom of the storage bin 51 corresponding to the mixing vessel 31. The powder dispensing mechanism is used to control a quantitative amount of powder to fall into the mixing vessel 31 through the second discharge port 52. A hopper 2 is integrally or detachably installed at the second discharge port 52, and the hopper 2 is directly opposite the mixing vessel 31. The powder dispensing device is used to control a quantitative amount of powder to fall into the hopper 2 through the second discharge port 52.

[0104] With this design, the storage bin 51 is used to store the powder. The powder can fall into the bin first through the second discharge port 52, and then into the bin 2. The bin 2 can assist the powder in falling into the mixing vessel 31, preventing the powder from drifting outside the mixing vessel 31 during the falling process. The structure is simple and easy to use.

[0105] In this embodiment, the powder feeding device is used in conjunction with the height adjustment device in the powder mixing device 22. The height of the mixing vessel 31 is adjusted by the height adjustment device so that the inlet of the mixing vessel 31 is closer to the second discharge port 52. This can effectively prevent the powder from falling outside the mixing vessel 31 during the falling process, thus preventing powder waste and improving the performance.

[0106] In an embodiment of the present invention, the powder dispensing mechanism includes a rotating powder dispensing part 62 rotatably installed in the storage bin 51. The rotating powder dispensing part 62 contains powder. The bottom of the rotating powder dispensing part 62 has a discharge port corresponding to the second discharge port 52. When the second discharge port 52 or the bin 2 rotates to a preset position (directly above the inlet of the mixing vessel 31), the powder in the storage bin 51 falls into the mixing vessel 31 or the bin 2 through the discharge port and the second discharge port 52.

[0107] Furthermore, the rotating powder dispensing part 62 can be a rotating disc or a rotating bracket. The rotating powder dispensing part 6 can be configured as a single compartment or can include multiple independently configured compartments. The dimensions of each compartment can be the same or different, and the compartment contains a preset amount of powder.

[0108] When the second discharge port 52 rotates to the preset position (directly above the inlet of the mixing vessel 31), the rotating powder discharge part 62 rotates until the discharge port and the second discharge port 52 are fully or partially overlapped, and the powder in the storage bin 51 falls into the mixing vessel 31 or the bin 2 through the discharge port and the second discharge port 52 in sequence.

[0109] As shown in Figures 3, 4 and 5, in an embodiment of the present invention, the top of the silo 2 is also provided with a feed inlet for loading powder into the silo 2. A sealing cover is provided at the feed inlet. The powder in the silo 2 is sealed and stored through the sealing cover and the silo door 4 to prevent the powder from deteriorating due to moisture.

[0110] In an embodiment of the present invention, the hopper 2 can be integrally fixed on the platform 6, and the hopper 2 and the platform 6 can be removed at the same time for cleaning or maintenance.

[0111] In an embodiment of the present invention, the hopper 2 may also be detachably installed on the platform 6, and each hopper 2 may be removed individually for cleaning or maintenance.

[0112] The hopper 2 can be funnel-shaped, cylindrical, or inverted funnel-shaped, and there are no restrictions on its shape.

[0113] In an embodiment of the present invention, the hopper door 4 is integrally or detachably installed at the first discharge port 3. Before the hopper 2 reaches the preset position (directly above the inlet of the mixing vessel 31), the hopper door 4 remains closed. When the hopper 2 reaches the preset position (directly above the inlet of the mixing vessel 31), the door opening device opens the hopper door 4 by directly acting on the hopper door 4 or by acting on the hopper door locking device.

[0114] When the door opening device opens the hopper door 4 by directly acting on the hopper door 4, the hopper door 4 is set at the first material discharge port 3 by horizontal swinging, horizontal sliding or hinge. An elastic element (not shown in the figure) is provided between the hopper door 4 and the hopper 2 to keep the hopper door 4 closed, such as a helical spring, a plane spring, an elastic rope, a torsion spring, etc., which are not limited here.

[0115] With this design, the hopper door 4 can be installed at the first discharge port 3 in a normally closed manner. Before the hopper 2 reaches the preset position (directly above the inlet of the mixing vessel 31), the hopper door 4 remains closed. After the hopper 2 completes the feeding of powder and moves away from the preset position (directly above the inlet of the mixing vessel 31), the door opening device returns to the state before acting on the hopper door 4, and the hopper door 4 returns to the closed state under the action of the elastic element, thereby realizing the normally closed state of the hopper door 4.

[0116] Of course, the door opening device can be a motor directly connected to the compartment door 4. The motor can be a rotary motor or a linear motor, which directly controls the opening or closing of the compartment door 4.

[0117] Before the material hopper 2 reaches the preset position (directly above the inlet of the mixing vessel 31), the motor controls the hopper door 4 to remain closed; when the material hopper 2 reaches the preset position (directly above the inlet of the mixing vessel 31), the motor controls the hopper door 4 to swing horizontally, slide horizontally, or rotate along the hinge axis, thereby opening the hopper door 4; after the material hopper 2 has finished dispensing the powder and moved away from the preset position (directly above the inlet of the mixing vessel 31), the motor controls the hopper door 4 to swing horizontally, slide horizontally, or rotate in the opposite direction along the hinge axis, thereby achieving the normal closure of the hopper door 4.

[0118] When the opening device opens the hopper door 4 by acting on the hopper door locking device, the hopper door 4 is hinged at the first discharge port 3 and remains freely openable and closable. Before the hopper 2 reaches the preset position (directly above the inlet of the mixing vessel 31), the hopper door 4 remains closed under the action of the hopper door locking device; when the hopper 2 reaches the preset position (directly above the inlet of the mixing vessel 31), the opening device acts on the hopper door locking device, the hopper door locking device releases the hopper door 4, and the hopper door 4 opens under its own gravity; after the hopper 2 has finished discharging the powder and moved away from the preset position (directly above the inlet of the mixing vessel 31), the hopper door 4 remains open.

[0119] As shown in Figure 24, in the first embodiment of the silo door locking device disclosed in this invention, the silo door locking device includes a swing arm 14 hinged to the silo 2. The hinge point of the swing arm 14 is located in its middle, and a hook 15 is provided at the bottom end of the swing arm 14. The hook 15 is used to hook the free end of the silo door 4 to keep the silo door 4 in a closed state. An elastic element (not shown in the figure), such as a coil spring or elastic rope, is provided between the swing arm 14 and the side wall of the silo 2 to maintain the hook 15 hooking the free end of the silo door 4. When the upper end of the swing arm 14 is pressed, the hook 15 disengages from the silo door 4, thereby opening the silo door 4.

[0120] As shown in Figure 25, in the second embodiment of the silo door locking device disclosed in this invention, the silo door locking device includes a swing arm 14 hinged to the silo 2. The hinge point of the swing arm 14 is located at its top, and a hook 15 is provided at the bottom end of the swing arm 14. The hook 15 is used to hook the free end of the silo door 4 to keep the silo door 4 in a closed state. An elastic element (not shown in the figure), such as a coil spring or elastic rope, is provided between the swing arm 14 and the side wall of the silo 2 to maintain the hook 15 hooking the free end of the silo door 4. When the middle part of the swing arm 14 is pressed, the hook 15 disengages from the silo door 4, thereby opening the silo door 4.

[0121] As shown in Figure 26, in the third embodiment of the silo door locking device disclosed in this invention, the silo door locking device includes a push block 101 slidably disposed on the silo 2. A hook 15 is provided at the bottom end of the push block 101. The hook 15 is used to hook the free end of the silo door 4 to keep the silo door 4 closed. An elastic element, such as a coil spring or elastic rope, is provided between the push block 101 and the silo 2 to maintain the hook 15 hooking the free end of the silo door 4; no limitation is made here. When the top of the push block 101 is pressed, the push block 101 drives the hook 15 to move downwards, causing the hook 15 to disengage from the silo door 4, thereby opening the silo door 4.

[0122] In some embodiments of the present invention, various implementations of the door opening device are disclosed:

[0123] As shown in Figures 3 and 24 to 26, in the first embodiment of the door opening device disclosed in this invention, the door opening device opens the compartment door 4 by acting on the compartment door locking device. The door opening device includes a push block 10 installed on the machine body 1. When the platform 6 drives the hopper 2 to rotate to a preset position above the mixing vessel 31 (directly above the inlet of the mixing vessel 31), the push block 10 presses against the compartment door locking device (the upper end of the swing arm 14, the middle part of the swing arm 14, or the top of the pressing block 101) so that the hook 15 disengages from the compartment door 4, thereby opening the compartment door 4.

[0124] Furthermore, the push block 10 may be provided with a first protrusion, and the door locking device is provided with a second protrusion corresponding to the first protrusion. When the platform 6 drives the hopper 2 to rotate to the preset position above the mixing vessel 31, the first protrusion on the push block 10 presses against the second protrusion on the door locking device (the upper end of the swing arm 14, the middle of the swing arm 14, or the top of the push block 101) so that the hook 15 disengages from the door 4, thereby opening the door 4.

[0125] The first implementation of the door opening device has a simple structure. The door 4 will only open when the material bin 2 reaches directly above the inlet of the mixing vessel 31, to prevent the material powder from spilling out due to premature opening of the door 4.

[0126] As shown in Figure 4, in the second embodiment of the door opening device disclosed in this invention, the door opening device opens the compartment door 4 by acting on the compartment door locking device. The door opening device includes a push rod 11 slidably mounted on the machine body 1 and a cam 111 mounted on the platform 6. The cam 111 rotates with the platform 6. The larger end of the cam 111 acts on the inner end of the push rod 11, and the outer end of the push rod 11 faces the compartment door locking device. When the platform 6 drives the hopper 2 to rotate to a preset position above the mixing container 31, the cam 111 pushes the outer end of the push rod 11 to press against the compartment door locking device (the upper end of the swing arm 14, the middle part of the swing arm 14, or the top of the push block 101), so that the hook 15 disengages from the compartment door 4, thereby opening the compartment door 4. Of course, a return spring that retracts the push rod 11 inward can also be provided on the platform 8 for better performance.

[0127] The second implementation of the door opening device has a simple structure. The cam 111 is driven to rotate by the platform 6. The hopper 2 will only open the door 4 when it reaches directly above the mixing vessel 31, which prevents the hopper 4 from opening too early and causing the powder to spill out. At the same time, it reduces the use of electrical components and lowers the failure rate.

[0128] As shown in Figure 5, in the third embodiment of the door opening device disclosed in this invention, the door opening device opens the bin door 4 by acting on the bin door locking device. The door opening device includes a power component 12 mounted on the machine body 1 capable of outputting linear motion. When the platform 6 drives the hopper 2 to rotate to a preset position above the mixing container 31, the power output end of the power component 12 extends out and presses against the bin door locking device (the upper end of the swing arm 14, the middle part of the swing arm 14, or the top of the push block 101) to trigger the bin door 4 to open. The power component 12 can be a linear motor, electromagnet, etc.

[0129] The third embodiment of the door opening device has a simple structure. The door 4 is triggered to open by the power component 12 pressing the door locking device (the upper end of the swing arm 14, the middle part of the swing arm 14, or the top of the push block 101). It is simple, convenient, and easy to control.

[0130] As shown in Figure 27, in the fourth embodiment of the door opening device disclosed in this invention, the door opening device opens the door 4 by directly acting on the door 4, and the door 4 is set at the first discharge port 3 in a horizontal swing manner. The door opening device includes a push block 10 installed on the machine body 1. When the platform 6 drives the hopper 2 to rotate to a preset position above the mixing vessel 31 (directly above the mixing vessel 31), the push block 10 directly presses against the door 4, so that the door 4 swings along the swing center axis, thereby opening the door 4. This reduces the number of parts used, makes the structure simpler, is easier to maintain, and is more efficient.

[0131] In the fifth embodiment of the door opening device disclosed in this invention, the door opening device opens the door 4 by directly acting on the door 4, and the door 4 is set at the first discharge port 3 in a horizontal swing manner. The door opening device includes a push rod 11 slidably set on the machine body 1 and a cam 111 set on the platform 6. The cam 111 rotates with the platform 6. The larger end of the cam 111 acts on the inner end of the push rod 11, and the outer end of the push rod 11 faces the door 4. When the platform 6 drives the hopper 2 to rotate to the preset position above the mixing vessel 31, the cam 111 pushes the outer end of the push rod 11 to press against the door 4, so that the door 4 swings along the swing center axis and thus opens the door 4. This reduces the number of parts used, makes the structure simpler, is easier to maintain, and is more efficient.

[0132] In the sixth embodiment of the door opening device disclosed in this invention, the door opening device opens the bin 4 by directly acting on the bin door 4, and the bin door 4 is set at the first discharge port 3 in a horizontal swing manner. The door opening device includes a power component 12 mounted on the machine body 1 that can output linear motion. When the platform 6 drives the hopper 2 to rotate to a preset position above the mixing vessel 31, the power output end of the power component 12 extends out and presses against the bin door 4, so that the bin door 4 swings along the swing center axis, thereby opening the bin door 4. This reduces the number of components used, makes the structure simpler, facilitates maintenance, and increases efficiency. The power component 12 can be a linear motor, electromagnet, etc.

[0133] As shown in Figure 28, in the seventh embodiment of the door opening device disclosed in this invention, the door opening device opens the door 4 by directly acting on the door 4, and the door 4 is set at the first material outlet 3 in a horizontal sliding manner. The door opening device includes a push block 10 installed on the machine body 1. When the platform 6 drives the hopper 2 to rotate to a preset position above the mixing vessel 31 (directly above the mixing vessel 31), the push block 10 directly presses against the door 4, so that the door 4 slides along the slide rail and thus opens the door 4. This reduces the number of parts used, makes the structure simpler, is easier to maintain, and is more efficient.

[0134] In the eighth embodiment of the door opening device disclosed in this invention, the door opening device opens the door 4 by directly acting on the door 4, and the door 4 is horizontally slidably disposed at the first material discharge port 3. The door opening device includes a push rod 11 slidably disposed on the machine body 1 and a cam 111 disposed on the platform 6. The cam 111 rotates with the platform 6. The larger end of the cam 111 acts on the inner end of the push rod 11, and the outer end of the push rod 11 faces the door 4. When the platform 6 drives the hopper 2 to rotate to a preset position above the mixing vessel 31, the cam 111 pushes the outer end of the push rod 11 to press against the door 4, so that the door 4 slides along the slide rail and thus opens the door 4. This reduces the number of parts used, makes the structure simpler, is easier to maintain, and is more efficient.

[0135] In the ninth embodiment of the door opening device disclosed in this invention, the door opening device opens the bin 4 by directly acting on the bin door 4, and the bin door 4 is horizontally slidably disposed at the first material discharge port 3. The door opening device includes a power component 12 mounted on the machine body 1 capable of outputting linear motion. When the platform 6 drives the hopper 2 to rotate to a preset position above the mixing vessel 31, the power output end of the power component 12 extends out and presses against the bin door 4, causing the bin door 4 to slide along the slide rail and thus open the bin door 4. This reduces the number of components used, simplifies the structure, facilitates maintenance, and increases efficiency. The power component 12 can be a linear motor, electromagnet, etc.

[0136] As shown in Figure 29, in the tenth embodiment of the door opening device disclosed in this invention, the door opening device directly acts on the bin door 4 to open the bin door 4, and the bin door 4 is arranged at the first material discharge port 3 in a horizontal swing manner. The door opening device includes a drive motor 24 disposed on the bin 2 for driving the bin door 4 to open and close. By directly acting on the bin door 4 with the drive motor 24, the bin door 4 is opened by horizontal swing, which is highly efficient and has a simple structure.

[0137] Among them, the drive motor 24 is a rotary motor. The power shaft of the drive motor 24 can be directly set as the swing shaft of the door 4, directly driving the door 4 to open and close; the power shaft of the drive motor 24 can also be connected to the swing shaft of the door 4 through a transmission gear set, indirectly driving the door 4 to open and close, without any restrictions.

[0138] As shown in Figure 30, in the eleventh embodiment of the door opening device disclosed in this invention, the door opening device directly acts on the bin door 4 to open the bin door 4, and the bin door 4 is hinged at the first material discharge port 3. The door opening device includes a drive motor 24 mounted on the bin 2 for driving the bin door 4 to open and close. By having the drive motor 24 directly act on the bin door 4, the bin door 4 is horizontally swung open, resulting in high efficiency and a simple structure.

[0139] Among them, the drive motor 24 is a rotary motor. The power shaft of the drive motor 24 can be directly set as the hinge shaft of the compartment door 4, directly driving the compartment door 4 to open and close; the power shaft of the drive motor 24 can also be connected to the hinge shaft of the compartment door 4 through a transmission gear set, indirectly driving the compartment door 4 to open and close, without any restrictions.

[0140] As shown in Figure 31, in the twelfth embodiment of the door opening device disclosed in this invention, the door opening device directly acts on the bin door 4 to open the bin door 4, and the bin door 4 is horizontally slidably disposed at the first material discharge port 3. The door opening device includes a drive motor 24 disposed on the bin 2 for driving the bin door 4 to open and close. The drive motor 24 can be a linear motor or an electromagnet, etc. By directly acting on the bin door 4, the bin door 4 is horizontally slid open, which is highly efficient and has a simple structure.

[0141] The drive shaft of the motor 24 can be directly connected to the door 4, directly driving the door 4 to slide horizontally to achieve opening and closing; the drive shaft of the motor 24 can also be indirectly connected to the door 4 through a transmission lever to achieve opening and closing of the door 4, thereby reducing the stroke of the motor 24, saving space, and making it more compact.

[0142] In embodiments of the present invention, the powder dispensing device has the function of automatically dispensing water into the mixing vessel 31. Four implementation methods for achieving the automatic water dispensing function are given below.

[0143] As shown in Figures 8 and 9, in the first embodiment of the automatic water discharge function disclosed in this invention, a water outlet pipe 17 for connecting to a water supply device is installed on the machine body 1. The water outlet pipe 17 has a water outlet 18 for discharging water into the rinsing container 31. The water outlet 18 is located below the material bin 2 or the storage bin 51. The water outlet pipe section 19 is installed on the machine body 1 in a manner that allows it to swing left and right. The machine body 1 is provided with a first power device for driving the water outlet pipe section 19 to swing. The first power device can be a swing motor installed on the machine body 1 or other structures. The power output end of the power device is connected to the water outlet pipe section 19, thereby driving the water outlet pipe section 19 to swing. When the water discharge pipe section 19 swings so that the water discharge port 18 is below the material discharge port, the water discharge port can discharge water into the mixing vessel. When the water discharge pipe section swings so that the water discharge port leaves the first material discharge port 3, it can avoid obstructing the falling of the powder and at the same time prevent the powder from falling onto the water discharge pipe section 19.

[0144] When the powder in the hopper 2 falls into the mixing vessel 31, the drain outlet 18 is located directly below the first discharge port 3 when the drain pipe section 19 swings to one side. When the drain pipe section 19 continues to swing to one side or the other side, the drain outlet 18 moves away from the first discharge port 3. Figures 7 and 8 show the state when the drain outlet 18 moves away from the first discharge port 3 when the drain pipe section 19 continues to swing to one side or the other side.

[0145] As shown in Figures 10 and 11, in the second embodiment of the automatic water discharge function disclosed in this invention, a water outlet pipe 17 for connecting to a water supply device is installed on the machine body 1. The water outlet pipe 17 has a water outlet 18 for discharging water into the rinsing container 31. The water outlet 18 is located below the material bin 2 or the storage bin 51. The water outlet pipe section 19 is slidably connected to the machine body 1 in a way that allows it to extend and retract. The machine body 1 is provided with a second power device for driving the extension and retraction of the water outlet pipe section 19. The second power device can be a linear motor installed on the machine body 1 or other structures. The power output end of the second power device is connected to the water outlet pipe section 19, thereby driving the extension and retraction of the water outlet pipe section 19.

[0146] After the powder in the hopper 2 falls into the mixing vessel 31, the water discharge pipe section 19 extends forward to directly above the mixing vessel 31 to discharge water. After discharging, the water discharge pipe section 19 retracts, and the water outlet 18 moves to its initial position. Figure 10 shows the water discharge pipe section 19 with its extension forward, and Figure 11 shows the water discharge pipe section 19 with its retraction backward. This design also applies to powder dispensing devices with a storage hopper 51. With the water discharge pipe section 19 extended, the water outlet 18 can discharge water into the mixing vessel 31. The retraction of the water discharge pipe section 19 avoids obstructing the falling powder and prevents powder from falling onto the water discharge pipe section 19.

[0147] As shown in Figure 12, in the third embodiment of the automatic water dispensing function disclosed in this invention, a water outlet pipe 17 for connection to a water supply device is installed on the machine body 1. The water outlet pipe 17 has a water outlet 18, which is used to dispense water into the mixing container 31. The water outlet pipe section 19 where the water outlet 18 is located is above the material bin 2 or the storage bin 51. When the material bin 2 rotates to a set position with the platform 6, water can be dispensed into the material bin 2 through the water outlet 18. With the above structure, the powder in the material bin 2 can be flushed out at the same time as water is dispensed, so that the powder falls better and the powder and water are pre-mixed, thus improving the mixing effect.

[0148] As shown in Figures 13 and 14, in the fourth embodiment of the automatic water dispensing function disclosed in this invention, a notch 8 is provided between adjacent hoppers 2. A water outlet pipe 17 for connecting to a water supply device is installed on the machine body 1. The water outlet pipe 17 is located above the notch 8 and has a water outlet 18 for dispensing water into the mixing container 31. The water outlet pipe section 19 where the water outlet 18 is located is located above the hopper 2. When the notch 8 moves above the mixing container 31, the water outlet 18 dispenses water, which enters the mixing container 31 through the notch 8. The water outlet pipe section 19 where the water outlet 18 is located is fixed relative to the platform 6 or driven to rotate by a power device. After the platform 6 carries the hopper 2 to the set position to complete the powder dispensing, the platform 6 continues to rotate so that the water outlet 18 is directly facing the mixing container 31. With this structure, the powder is added and water is added to the mixing vessel 31 sequentially, and the two are independent and do not affect each other.

[0149] In an embodiment of the present invention, the powder feeding device is equipped with a vibration motor 16 to ensure the smooth falling of the powder in the hopper 2 and to prevent the powder from being difficult to fall due to clumping, moisture, or other reasons. Two implementations of the vibration motor 16 are given below.

[0150] As shown in Figure 3, in the first embodiment of the vibration motor 16 of the present invention, a vibration motor 16 is installed on the hopper 2. The vibration motor 16 can be installed on the side wall of the hopper 2. Through the vibration of the vibration motor 16, the powder in the hopper 2 can fall smoothly.

[0151] As shown in Figures 2 and 15, in the second embodiment of the vibration motor 16 of the present invention, the body 1 is equipped with a vibration motor 16, which has vibration protrusions. When the platform 6 drives the hopper 2 to rotate to a preset position above the mixing vessel 31, the vibration protrusions on the vibration motor 16 can act on the hopper 2 to cause the powder to fall. In this embodiment, only one vibration motor 16 is needed, which simplifies the structure and reduces costs. At the same time, the friction between the hopper 2 and the platform 6 is small during vibration, which can reduce noise.

[0152] In embodiments of the present invention, the powder dispensing device may be made entirely or partially of transparent material. This may include the hopper 2, the hopper door 4, and the outer shell of the powder dispensing device all being made of transparent material, or the hopper 2 and the outer shell of the powder dispensing device being made of transparent material, or the hopper 2 and the storage hopper 51 being made of transparent material. As long as the amount of powder in the hopper and the powder dispensing situation can be observed from the outside, there are no restrictions.

[0153] The transparent material can be glass, plastic, or other transparent materials that meet the standards for infant food, and there are no restrictions on its use.

[0154] Of course, in other embodiments of the present invention, the powder dispensing device may also adopt other mechanisms that can realize the powder dispensing function in the prior art, such as control valves, and there is no limitation here.

[0155] As shown in Figures 2 to 14, the mixing device disclosed in this invention specifically includes a support base 23 and a container seat 24. The container seat 24 is used to hold the mixing container 31. The support base 23 is connected to the body 1, and the container seat 24 is movably mounted on the support base 23. The container seat 24 is mounted on the support base 23 in a manner that allows it to rotate around a vertical axis. A motor mounted on the support base 23 is connected to the bottom of the container seat 24. The forward and reverse rotation of the motor can drive the container seat 24 to rotate in both directions, thereby causing the mixing container 31 to be shaken evenly. In other embodiments of this invention, the movement of the container seat 24 is not limited to forward and reverse rotation; it can also shake up and down, shake left and right, etc. This mixing device can prevent the powder from adhering to the inner wall of the mixing container 31, and it is less likely to generate air bubbles during the mixing process, resulting in a better mixing effect.

[0156] The container base 24 is cup-shaped, and an elastic retaining ring 25 is installed at the rim of the container base 24. When a brewing container 31 is placed on the container base 24, the elastic retaining ring 25 fits over the brewing container 31 to secure it. A height adjustment device is located between the main body 1 and the support base 23 to adjust the height of the support base 23. The elastic retaining ring 25 is used to keep the brewing container 31 fixed, preventing the brewing container 31 from bumping against the container base 24, and also to facilitate the removal of the brewing container 31. The mixing device can automatically mix the beverage, further freeing up hands and making it convenient to use.

[0157] As shown in Figures 3 to 12, in some embodiments of the present invention, the height adjustment device can adjust the height of the mixing container and fix its height position after the mixing container is moved to the target position, preventing the powder from falling outside the bottle during the falling process and causing waste of powder, and it can be applied to mixing containers of various sizes.

[0158] The following are several embodiments of the height adjustment device. Of course, the height adjustment device is not limited to the following embodiments, but also includes other embodiments in the prior art that can realize the height adjustment and height position fixation of the brewing vessel.

[0159] The height adjustment device includes a sliding groove 9 on the body 1. The mixing device is provided with a sliding block 221 that slides along the sliding groove 9. The mixing device slides along the sliding groove 9 via the sliding block 221 to adjust the height position of the mixing device. The sliding groove 9 can limit its lateral movement and forward and backward movement, ensuring stable lifting and lowering of the mixing device. It can be used for various heights of mixing containers 31, making it easy to pick up and put down the mixing containers 31. It prevents powder from spilling from mixing containers 31 with a small height and prevents the mixing containers 31 with a large height from being difficult to pick up. At the same time, it can make the inlet of the mixing container 31 closer to the discharge port 3 and the water outlet 18, preventing powder from falling outside the mixing container 31 or water from splashing out of the mixing container 31.

[0160] Furthermore, this invention discloses the following methods for fixing the height position of the mixing device. Of course, the methods for fixing the height position of the mixing device are not limited to the following embodiments, but also include other embodiments in the prior art that can achieve fixing the height position of the mixing device, as detailed below:

[0161] As shown in Figure 16, in the first embodiment where the height of the mixing device is fixed, after manually raising the mixing device to the target position, a first pad 13 is placed at the bottom of the mixing device to fix the height of the mixing device.

[0162] In the second embodiment where the height position of the mixing device is fixed, the height adjustment device includes a first fixing part that is separately provided or installed on the body 1 or on the water storage container 20. The mixing device is provided with a second fixing part corresponding to the first fixing part. When the mixing device is manually raised to the target height, the first fixing part and the second fixing part cooperate to lock and fix the height position of the mixing device.

[0163] The first fixing part and the second fixing part can be several hooks, fixing blocks, slide rails, or sliders that cooperate with each other. For example, the first fixing part can be a row of hooks, and the second fixing part can be a fixing groove on the mixing device corresponding to the hooks. After the mixing device reaches the target height position, the fixing groove is hooked on the hook to fix the height position of the mixing device. Alternatively, the first fixing part can be one or several fixing blocks, and the second fixing part can be a fixing stop on the mixing device corresponding to the hooks. After the mixing device reaches the target height position, the fixing stop is fixed on the fixing block to fix the height position of the mixing device. Alternatively, the first fixing part can be multiple slide rails set at different height positions, and the second fixing part can be sliders on the mixing device corresponding to the hooks. After the mixing device reaches the target height position, the sliders slide into the slide rails at the corresponding height positions to fix the height position of the mixing device.

[0164] In the third embodiment where the height position of the mixing device is fixed, the height adjustment device includes a support frame that is set separately, installed on the body 1, or installed on the water storage container. The support frame is provided with multiple fixing holes or fixing slide rails located at different height positions. One or more sets of bolts or buckles are provided on both sides of the mixing device corresponding to the fixing holes. When the mixing device reaches the target height, one or more sets of bolts or buckles on the mixing device can be locked in the fixing holes or slide rails to fix the height position of the mixing device.

[0165] As shown in Figure 17, in the fourth embodiment where the height position of the mixing device is fixed, the height adjustment device includes at least one second pad 131 that is separately set or installed on the body 1 or on the water storage container 20 and is slidably installed on the body 1. When the mixing device reaches the target height, the at least one second pad 131 that is separately set or installed on the body 1 or on the water storage container 20 is pulled to the bottom of the mixing device to fix the height position of the mixing device. The structure is simple and easy to use.

[0166] As shown in Figures 18 and 19, in the fifth embodiment where the height of the mixing device is fixed, the height adjustment device includes a fixedly installed ratchet 26 and a stop 27 hinged to the corresponding ratchet 26. The ratchet 26 passes through the bottom of the mixing device and guides the adjustment of the height of the mixing device. When the mixing device is raised or lowered to the target height position, the ratchet 26 and the stop 27 cooperate to lock and fix the position of the mixing device.

[0167] Specifically, as shown in Figures 20 and 21, the stop block 27 includes a stop block body 271 hinged to the support base 23. A pressing block 272 is provided on the side of the stop block body 271 away from the ratchet 26. An inclined surface 273 is provided on the side of the stop block body 271 close to the ratchet 26 corresponding to the ratchet 26. A spring 274 is installed between the pressing block 272 and the support base 23.

[0168] When in use, press the pressing block 272 to disengage the inclined surface 273 of the stop block body 271 from the ratchet 26, thereby unlocking the ratchet and manually raising the mixing device to the target position. At this time, the spring 274 is in a compressed state.

[0169] After the mixing device reaches the target position, the pressing block 272 is released, and the inclined surface 273 of the stop block body 271 is pushed by the spring force of the spring 274 and locked into the ratchet teeth of the ratchet rack 26, thereby locking the position of the mixing device.

[0170] As shown in Figure 22, in some embodiments of the present invention, the height adjustment device further includes a vertical cylinder 261 mounted on the machine body 1 and driven to rotate by a third power device. The mixing device includes a support base 23. The vertical cylinder 261 and the support base 23 are provided with meshing drive threads 275. The support base 23 is vertically slidably connected to the machine body 1, thereby driving the mixing device to be vertically slidably connected to the machine body 1.

[0171] The third power unit can be a motor fixed relative to the machine body 1. The motor shaft and the vertical cylinder 261 are equipped with meshing gears. The operation of the motor drives the vertical cylinder 261 to rotate. This is a preferred embodiment of the power unit. Of course, the power unit can also adopt other structures. The third power unit drives the vertical cylinder 261 to rotate. Under the meshing action of the drive thread 275, and with the support seat 23 only able to slide vertically, the support seat 23 can be raised and lowered, thereby driving the mixing device to rise and fall. The advantage of using this structure is that the raising and lowering of the support seat 23 is relatively smooth, and the mixing vessel 31 can also be raised and lowered smoothly to achieve height position locking.

[0172] Furthermore, as shown in Figure 23, in order to achieve a sliding connection between the support base 23 and the body 1, the support base 23 is provided with two slide rail ribs 32, and the body is provided with two slide rail grooves 33. The two slide rail ribs 32 are inserted into different slide rail grooves 33 respectively. Of course, the sliding connection method is not limited to this.

[0173] In some embodiments of the present invention, the height adjustment device includes a sliding groove 9 disposed on the body 1, a sliding block 221 disposed on the mixing device that slides along the sliding groove 9, the mixing device being raised and lowered along the sliding groove 9 via the sliding block 221, and also includes a fixedly disposed ratchet 26 and a stop block 27 hinged to the corresponding ratchet 26, the ratchet 26 passing through the bottom of the mixing device and guiding the mixing device to rise and fall, and also includes a vertical cylinder 261 mounted on the body 1 and driven to rotate by a third power device, the vertical cylinder 261 and the mixing device being provided with meshing drive threads 275, and a support base 23 being vertically slidably connected to the body 1.

[0174] In some embodiments of the present invention, the water storage container 20 installed on the body 1 has an electric heating or heat preservation function. A water pump 21 for drawing water from the water storage container 20 is installed in the water storage container 20. The water outlet pipe 17 is connected to the water outlet of the water pump 21. The water outlet pipe 17 has a drain outlet 18, which is used to drain water into the storage bin 2 or the mixing container 31.

[0175] The water storage container 20 can be pre-filled with warm water at a suitable temperature. Starting the water pump allows for automatic water dispensing, eliminating the need to dispense water separately each time a beverage is prepared, making it more convenient. The advantages of the first beverage preparation machine disclosed in this invention lie in the structure of the machine body and the arrangement of its various parts. The entire beverage preparation machine features an integrated design, resulting in a compact structure and ease of use.

[0176] The advantages of the beverage mixing machine disclosed in this invention are that the structure of the machine body and the arrangement of the various parts on the machine body are more compact, the number of parts is reduced, the failure rate is reduced, and it is easy to use.

[0177] It should be noted that the mixing vessels mentioned above are utensils used for mixing beverages, such as baby bottles. The reason for mentioning mixing vessels is to facilitate the description of the usage of the present invention. In the present invention, neither the powder dispensing device, the powder mixing device, nor the beverage mixing machine necessarily includes mixing vessels.
