Description

A milk powder storage device, a milk powder dispensing device, and an automatic milk maker. Technical Field

[0001] This utility model relates to the field of beverage preparation equipment technology, specifically to a milk powder storage device, a milk powder dispensing device, and an automatic milk maker. Background Technology

[0002] A formula dispensing device is a machine that can automatically prepare formula, solving the problem of new mothers preparing formula while caring for their babies. A formula dispensing device typically includes a formula dispensing unit, a water supply unit, and a mixing unit. The formula dispensing unit is used to add formula powder, the water supply unit is used to add water, and the mixing unit is used to mix the formula powder and water evenly.

[0003] In automatic formula dispensers, the formula dispensing device is crucial. To address the issue of precise formula dispensing, one type of device includes a formula storage chamber for holding large quantities of formula and a dispensing unit to gradually dispense the formula from the storage chamber. This type of device is time-consuming, and due to the stickiness of formula, it can adhere to the dispensing unit's components, leading to inaccurate dispensing. Another type of device includes a formula storage chamber with multiple compartments. Each compartment has a dispensing spout, and each spout has a lid. A predetermined amount of formula is placed in each compartment beforehand. To dispense, the lid of one compartment is opened, allowing the formula to dispense. However, because the lid is attached to the compartment, it may not open completely, resulting in uneven dispensing and formula sticking between the dispensing spout and the lid.

[0004] Based on the above analysis, existing milk powder dispensing devices, especially milk powder storage devices, have the following problems: 1. Inaccurate powder dispensing; 2. Incomplete powder dispensing; 3. Milk powder adhering between the milk powder hopper and its bottom cover. Therefore, given these problems, it is necessary to improve both the milk powder storage device and the milk powder dispensing device. Summary of the Invention

[0005] The purpose of this invention is to provide a milk powder storage device, a milk powder dispensing device, and an automatic milk maker to solve the problems of inaccurate powder dispensing, poor dispensing, and milk powder adhesion in the prior art.

[0006] In a first aspect, this utility model provides a milk powder storage device, including a rotating component that can be installed on a main body. The rotating component has multiple milk powder compartments around its rotation center. The bottom of each milk powder compartment has a powder discharge port. The bottom of the rotating component has multiple milk powder compartment bottom covers corresponding to the milk powder compartments. The milk powder compartment bottom covers are rotatably connected to the rotating component in a horizontal swinging manner. When the milk powder compartment bottom cover swings to one side, it can block the powder discharge port. When the milk powder compartment bottom cover swings to the other side, it can expose the powder discharge port. With the above structure, multiple milk powder compartments are set up, each of which can be pre-filled with an appropriate amount of milk powder. One filling can be used to make multiple bottles of milk. After the bottom cover of the milk powder compartment swings to expose the powder outlet, the milk powder in the compartment can fall completely into the bottle, and the amount of powder dispensed is relatively accurate. After the bottom cover of the milk powder compartment swings to one side, the powder outlet is fully exposed, and the milk powder falls into the bottle under the action of gravity, and the powder dispensing is relatively smooth. The bottom cover of the milk powder compartment opens by swinging, and the bottom cover of the milk powder compartment is rotatably connected to the rotating part. The milk powder compartment and the bottom cover of the milk powder compartment are not directly connected, which can avoid the milk powder being trapped between the two. During the process of the bottom cover of the milk powder compartment swinging to one side, the milk powder compartment can scrape off the milk powder adhering to the bottom cover of the milk powder compartment, which helps to maintain cleanliness.

[0007] Furthermore, the bottom cover of the milk powder compartment is arranged in a ring around the rotation center of the rotating component, and the bottom cover of the milk powder compartment is rotatably connected to the rotating component via a rotating shaft to achieve horizontal swinging of the bottom cover of the milk powder compartment. The rotating shaft is located between the rotation center of the milk powder compartment and the rotating component. The bottom covers of the milk powder compartment are centrally arranged on the rotating component, resulting in a compact structure that is easy to control.

[0008] Furthermore, the rotating shaft is located between the rotation center of the rotating component and the milk powder compartment. The relevant mechanism for opening the bottom cover of the milk powder compartment can be set between the milk powder compartment and the rotation center of the rotating component, which is compact and easy to control.

[0009] Furthermore, the part of the milk powder compartment bottom cover used to block the powder discharge port and the opening trigger part of the milk powder compartment bottom cover are located on the same side of the rotating connection of the milk powder compartment bottom cover. The advantage of the above structure is that when the rotating part rotates to bring the milk powder compartment close to the bottle, the milk powder compartment bottom cover is opened from the side that first enters the bottle opening, which reduces the risk of powder spillage and increases powder dispensing efficiency.

[0010] Furthermore, the milk powder hopper bottom cover includes a mounting part, a connecting part, and a sealing part connected in sequence. The mounting part of the milk powder hopper bottom cover is rotatably connected to the rotating component, and the sealing part of the milk powder hopper bottom cover is used to seal the powder discharge port. The connecting part is located on the side of the milk powder hopper near the rotation center of the rotating component. The upper end of the connecting part is connected to the mounting part, and the lower end of the connecting part is connected to the sealing part. With the above structure, the connecting part is located on one side of the milk powder hopper, and the sealing part is located below the milk powder hopper. The bottom cover part formed by the two can well adapt to the shape of the milk powder hopper. By setting the connecting part, the bottom cover of the milk powder hopper can be stably and flexibly rotatably connected to the rotating component. The overall design of the bottom cover of the milk powder hopper optimizes the structural space and is conducive to the compact design of the entire milk powder storage device.

[0011] Furthermore, the rotating component has a limiting part corresponding to the bottom cover of the milk powder compartment to restrict the bottom cover from swinging to one side. When the bottom cover swings to contact the limiting part, it can block the powder discharge port. An elastic reset element is provided between the bottom cover and the rotating component. When the side of the bottom cover near the limiting part swings away from the limiting part, the elastic reset element is used to bring that side of the bottom cover back close to the limiting part. With the above structure, the limiting part and the elastic reset element combine to ensure that the bottom cover of the milk powder compartment can maintain the blockage of the powder discharge port. After the bottom cover of the milk powder compartment is opened to discharge powder, the elastic reset element can make the bottom cover of the milk powder compartment automatically return to the state of blocking the powder discharge port, preventing residual powder in the compartment from falling and sticking to the automatic formula maker.

[0012] Furthermore, the milk powder compartment bottom cover and the rotating component are rotatably connected via a pivot to achieve horizontal swinging of the milk powder compartment bottom cover. The elastic reset element is a torsion spring mounted on the pivot, with one end of the torsion spring engaged with the milk powder compartment bottom cover and the other end engaged with the rotating component. With the above structure, the torsion spring is easy to install and provides a stable and reliable reset force for the milk powder compartment bottom cover.

[0013] Furthermore, the milk powder container is funnel-shaped. The funnel shape of the milk powder container facilitates concentrated powder dispensing and allows for the holding of a larger quantity of milk powder.

[0014] Secondly, this utility model also discloses a milk powder dispensing device, including a main body. The milk powder dispensing device includes the aforementioned milk powder storage device. A mounting base is provided at the bottom of the rotating component, and the mounting base is rotatably mounted on the main body. The rotating component is connected to the mounting base. With this structure, the mounting base serves as an intermediate component, allowing the rotating component to be rotatably connected to the main body.

[0015] Furthermore, the rotating component is detachably connected to the mounting base. The rotating component and the mounting base are detachably connected, and the assembly consisting of the rotating component, the milk powder container, and the bottom cover of the milk powder container can be removed from the main body for easy cleaning.

[0016] Furthermore, the bottom of the milk powder compartment cover is provided with a first contact block, which is located between the rotation center of the milk powder compartment cover and the part used to block the powder discharge port. The main body is equipped with a second contact block that can move up and down. An elastic buffer element is provided between the second contact block and the main body. When the rotating part rotates to the set powder discharge position of any milk powder compartment, the second contact block can touch the first contact block on the bottom cover of the corresponding milk powder compartment, so that the bottom cover of the milk powder compartment swings to expose the powder discharge port. When the rotating part continues to rotate a set angle, the first contact block can make the second contact block overcome the force of the elastic buffer element and move downward so that it passes over the second contact block. With the above structure, when the rotating part rotates, the second contact block can touch the first contact block, causing the bottom cover of the milk powder compartment to swing open and complete the milk powder dispensing. The second contact block can move up and down and is equipped with an elastic buffer element. After the rotating part continues to rotate, the second contact block can pass over the first contact block, and the first contact block is no longer affected by the second contact block, so that the bottom cover of the milk powder compartment can return to the closed state. The first contact block is located between the rotation center of the bottom cover of the milk powder compartment and the part used to block the milk powder dispensing port. When the rotating part rotates and the milk powder compartment is close to the bottle, the side of the milk powder dispensing port that is closer to the milk powder bottle is exposed first to dispense the milk powder. This not only dispenses the milk powder quickly, but also prevents the milk powder from spilling outside the bottle.

[0017] Furthermore, the mounting base or rotating component is equipped with multiple third contact blocks arranged around it, each corresponding to a milk powder container. The main body is equipped with a mechanical contact switch. When the rotating component rotates to a set position for any milk powder container, the third contact block corresponding to that container can contact the mechanical contact of the mechanical contact switch. With this structure, when the rotating component rotates and brings one milk powder container close to the milk powder bottle, the corresponding third contact block can contact the mechanical contact of the mechanical contact switch. The mechanical contact switch can be connected to the control circuit of an automatic milk maker, allowing the milk powder container to stop dispensing milk powder at a set position. The mechanical contact switch has the advantages of high precision, simple structure, and low cost.

[0018] Furthermore, the bottom of the rotating component is provided with a polygonal sleeve, and the top surface of the mounting base is provided with a polygonal post. A connecting handle spanning both sides of the upper opening of the polygonal sleeve allows the polygonal post to be inserted into the polygonal sleeve. The lower opening of the polygonal sleeve is provided with multiple elastic strips, and the outer circumference of the polygonal post corresponds to multiple positioning recesses on the elastic strips. A positioning protrusion is provided on the side of the elastic strip near the center of the polygonal sleeve. When the polygonal post is inserted into the polygonal sleeve, the positioning protrusion on the elastic strip can enter the corresponding positioning recess. With this structure, after the rotating component is connected to the mounting base, the cooperation between the polygonal post and the polygonal sleeve prevents relative rotation between them. By controlling the rotating component, the rotation angle can be accurately controlled. After the polygonal post is inserted into the polygonal sleeve, the positioning protrusion can enter the positioning recess, keeping the rotating component and the mounting base together. The connecting handle at the upper opening of the polygonal sleeve facilitates the installation and removal of the rotating component.

[0019] Furthermore, the rotating component is equipped with multiple tapping blocks corresponding to the milk powder compartments. These tapping blocks are located on the side of the milk powder compartment away from the rotation center of the rotating component. A vibration motor is mounted on the main body. When the rotating component rotates to the set milk powder dispensing position for any milk powder compartment, the contact of the vibration motor can contact the tapping block corresponding to that milk powder compartment. With this structure, as the milk powder compartment dispenses milk powder as the rotating component rotates to the set position, the contact of the vibration motor can continuously tap the tapping block corresponding to that milk powder compartment to promote the falling of milk powder within the compartment.

[0020] Thirdly, this utility model also discloses an automatic formula maker, which includes the aforementioned milk powder dispensing device. A power connection portion for connecting the output end of a power device is provided at the bottom center of the mounting base. A power device is mounted on the main body, and the power output end of the power device is connected to the power connection portion. With this structure, the power device can output power to drive the mounting base to rotate. The mounting base drives the rotating component to rotate, causing different milk powder compartments to reach the set dispensing position and opening the bottom cover of the milk powder compartment, thus realizing multiple milk powder dispensings. Combined with the water supply and mixing devices on the automatic formula maker, multiple formula preparations can be achieved.

[0021] In summary, the beneficial effects of this utility model are as follows: By improving the milk powder storage device, the milk powder dispensing device, and the automatic milk maker, this utility model enables multiple milk powder storage compartments, allowing for multiple preparations with a single filling. In conjunction with other parts of the automatic milk maker, it can achieve automatic opening and positioning of the milk powder compartments, and has the advantages of accurate powder dispensing, smooth powder dispensing, and no milk powder sticking between the milk powder compartment and the bottom cover.

[0030] Referring to Figures 1 to 4, in some embodiments of this utility model, a milk powder storage device is disclosed, including a rotating component 2 that can be installed on a main body 1. The rotating component 2 has a plurality of milk powder compartments 3 arranged around its rotation center. The bottom of the milk powder compartment 3 is provided with a powder discharge port 4. The device is characterized in that the bottom of the rotating component 2 is provided with a plurality of milk powder compartment bottom covers 5 corresponding to the milk powder compartment 3. The milk powder compartment bottom covers 5 are rotatably connected to the rotating component 2 in a horizontal swinging manner. When the milk powder compartment bottom cover 5 swings to one side, it can block the powder discharge port 4. When the milk powder compartment bottom cover 5 swings to the other side, it can expose the powder discharge port 4.

[0031] By setting multiple milk powder compartments 3, each compartment 3 can be pre-filled with an appropriate amount of milk powder, allowing for multiple milk preparations with a single filling. When the bottom cover 5 of the milk powder compartment swings to expose the powder outlet 4, the milk powder inside can fall completely into the bottle, ensuring accurate powder dispensing. When the bottom cover 5 of the milk powder compartment swings to one side, the powder outlet 4 is fully exposed, and the milk powder falls into the bottle under gravity, resulting in smooth dispensing. The bottom cover 5 of the milk powder compartment opens by swinging, and is rotatably connected to the rotating part 2. The milk powder compartment 3 and the bottom cover 5 are not directly connected, which can prevent powder from getting stuck between them. During the swinging process of the bottom cover 5, the milk powder compartment 3 can scrape off the milk powder adhering to the bottom cover 5, which helps to maintain cleanliness.

[0032] Referring to Figures 3, 4, and 6, in some embodiments of this utility model, the milk powder compartment bottom cover 5 is arranged in a ring around the rotation center of the rotating component 2. The milk powder compartment bottom cover 5 and the rotating component 2 are rotatably connected by a rotating shaft 6 to achieve horizontal swinging of the milk powder compartment bottom cover 5. The rotating shaft 6 is located between the rotation center of the rotating component 2 and the milk powder compartment 3. In the illustrated embodiments, the rotating shaft 6 is fixedly connected to the milk powder compartment bottom cover 5. With the above structure, the relevant mechanism for opening the milk powder compartment bottom cover 5 can be set between the rotation center of the rotating component 2 and the milk powder compartment 3, resulting in a compact structure that is easy to control. The milk powder hopper bottom cover 5 includes a mounting part 7, a connecting part 8, and a sealing part 9 connected in sequence. The mounting part 7 of the milk powder hopper bottom cover 5 is rotatably connected to the rotating part 2. In the illustrated embodiment, the rotating shaft 6 is fixedly connected to the mounting part 7. The sealing part 9 of the milk powder hopper bottom cover 5 is used to seal the powder discharge port 4. The connecting part 8 is located on the side of the milk powder hopper 3 near the rotation center of the rotating part 2. The upper end of the connecting part 8 is connected to the mounting part 7, and the lower end of the connecting part 8 is connected to the sealing part 9. With the above structure, the connecting part 8 is located on one side of the milk powder hopper 3, and the sealing part 9 is located below the milk powder hopper 3. The milk powder hopper bottom cover 5 formed by the two can well adapt to the shape of the milk powder hopper 3. By setting the connecting part 8, the milk powder hopper bottom cover 5 can be stably and flexibly rotatably connected to the rotating part 2. The overall design of the milk powder hopper bottom cover 5 optimizes the structural space and is conducive to the compact design of the entire milk powder storage device.

[0033] Referring to Figures 3, 4, and 6, in some embodiments of this utility model, the rotating member 2 is provided with a limiting part 10 corresponding to the bottom cover 5 of the milk powder compartment to restrict the bottom cover 5 of the milk powder compartment from swinging to one side. In the illustrated embodiments, the limiting part 10 is a protrusion provided on the rotating member 2. When the bottom cover 5 of the milk powder compartment swings to contact the limiting part 10, it can block the powder discharge port 4. An elastic reset element 11 is provided between the bottom cover 5 of the milk powder compartment and the rotating member 2. When the side of the bottom cover 5 of the milk powder compartment that is close to the limiting part 10 swings to deviate from the limiting part 10, the elastic reset element 11 is used to make that side of the bottom cover 5 of the milk powder compartment move closer to the limiting part 10 again. With the above structure, the limiting part 10 and the elastic reset element 11 are combined so that the bottom cover 5 of the milk powder compartment can keep blocking the powder discharge port 4. After the bottom cover 5 of the milk powder compartment is opened to discharge powder, the elastic reset element 11 can make the bottom cover 5 of the milk powder compartment automatically return to the state of blocking the powder discharge port 4, preventing residual powder in the compartment from falling and sticking to the automatic formula maker. In the embodiment shown in Figure 6, the elastic reset element 11 is a torsion spring mounted on the rotating shaft 6. One end of the torsion spring is secured to the bottom cover 5 of the milk powder compartment, and the other end is secured to the rotating component 2. With the above structure, the torsion spring is easy to install and provides a stable and reliable reset force for the bottom cover 5 of the milk powder compartment.

[0034] Referring to Figures 3, 4, and 6, in some embodiments of this utility model, the milk powder container 3 is a funnel shape with its lower end tilted away from the rotation center of the rotating component 2. With this structure, the milk powder container 3, being a funnel shape tilted to one side, avoids milk powder accumulating in the center and causing blockages when falling, resulting in smoother powder dispensing. The tilt of the lower end of the milk powder container 3 away from the rotation center of the rotating component 2 allows for the centralized arrangement of the milk powder containers 3 while also dispersing the powder dispensing ports 4 of each container 3. This compact distribution of the milk powder containers 3 facilitates individual control of powder dispensing from each container 3.

[0035] Referring to Figures 1, 3, 4, and 5, some embodiments of this utility model disclose a milk powder dispensing device, including a main body 1. This milk powder dispensing device includes the aforementioned milk powder storage device. A mounting base 15 is provided at the bottom of a rotating component 2, and the mounting base 15 is rotatably mounted on the main body 1. The rotating component 2 is detachably connected to the mounting base 15. Referring to Figure 1, in the illustrated embodiment, a connecting shaft is provided at the bottom of the mounting base 15, and a bushing is provided on the main body 1. The connecting shaft extends into the bushing, and a bearing is provided between the bushing and the connecting shaft, thereby enabling the rotating mounting base 15 to be rotatably mounted on the main body 1. With the above structure, the mounting base 15 serves as an intermediate component, allowing the rotating component 2 to be rotatably connected to the main body 1. The rotating component 2 and the mounting base 15 are detachably connected, and the part consisting of the rotating component 2, the milk powder compartment 3, and the milk powder compartment bottom cover 5 can be disassembled from the main body 1 for easy cleaning.

[0036] Referring to Figures 1, 6, and 7, in some embodiments of this utility model, a first contact block 12 is provided at the bottom of the milk powder compartment bottom cover 5. The first contact block 12 is located between the rotation center of the milk powder compartment bottom cover 5 and the part used to block the powder discharge port 4. A second contact block 13 that can move up and down is installed on the main body 1. An elastic buffer element 14 is provided between the second contact block 13 and the main body 1. When the rotating member 2 rotates to any milk powder compartment 3 at the set powder discharge position, the second contact block 13 can touch the first contact block 12 on the corresponding milk powder compartment bottom cover 5, thereby causing the milk powder compartment bottom cover 5 to swing so that the powder discharge port 4 is exposed. When the rotating member 2 continues to rotate at a set angle, the first contact block 12 can cause the second contact block 13 to move downward against the force of the elastic buffer element 14, so that it passes over the second contact block 13.

[0037] In the embodiment shown in Figure 7, the second contact block 13 is disposed on the base, the base has two guide cylinders on the left and right, the main body is provided with two guide posts, the two guide cylinders are respectively fitted on the two guide posts, and a bolt is installed on the top surface of each of the two guide posts. A baffle for preventing the guide cylinder from falling off the guide post is fitted on the bolt. A limiting post is provided on the bottom surface of the base, and a spring is fitted on the limiting post. The spring is located between the main body 1 and the base. This spring is the elastic buffer element 14. The contact surface between the first contact block 12 and the second contact block 13 is set as a wedge surface. With the above structure, when the rotating part 2 rotates, the second contact block 13 can touch the first contact block 12, causing the milk powder compartment bottom cover 5 to swing open and complete the powder dispensing. The second contact block 13 can move up and down and is equipped with an elastic buffer element 14. After the rotating part 2 continues to rotate, the first contact block 12 can pass over the second contact block 13. The first contact block 12 is no longer affected by the second contact block 13, so the milk powder compartment bottom cover 5 can return to the closed state. The first contact block 12 is located between the rotation center of the milk powder compartment bottom cover 5 and the part used to block the powder dispensing port 4. When the rotating part 2 rotates and the milk powder compartment 3 is close to the bottle, the side of the powder dispensing port 4 closest to the milk powder bottle is exposed first to dispense powder. This not only dispenses powder quickly but also prevents milk powder from spilling outside the bottle.

[0038] Referring to Figures 1, 3, and 5, in some embodiments of this utility model, a plurality of third contact blocks 17 are arranged around the mounting base 15 (in other embodiments of this invention, the third contact blocks 17 can also be provided on the rotating member 2). The third contact blocks 17 are correspondingly arranged with the milk powder compartments 3, and a control switch is provided on the main body 1. The control switch is a mechanical contact switch 18 or a Hall element, or a position sensor. The mechanical contact switch 18 can be a micro switch, limit switch, etc. When the rotating member 2 rotates to any milk powder compartment 3 in a set position, the third contact block 17 corresponding to that milk powder compartment 3 can act on the control switch. That is, the third contact block (17) touches the mechanical contact of the mechanical contact switch (18) or triggers the position sensor to work, or the Hall element contacts the signal. With the above structure, when the rotating part 2 rotates and one of the milk powder compartments 3 approaches the milk powder bottle, the corresponding third contact block 17 can touch the mechanical contact of the mechanical contact switch 18. The mechanical contact switch 18 can be connected to the control circuit of the automatic milk maker, so that the milk powder compartment 3 can rotate to a set position and stop to dispense milk powder.

[0039] Referring to Figures 1, 2, 4, and 5, in some embodiments of this utility model, the bottom of the rotating component 2 is provided with a polygonal sleeve 19, the top surface of the mounting base 15 is provided with a polygonal insert 20, the upper opening of the polygonal sleeve 19 is provided with a connecting handle 21 spanning both sides of the opening, the polygonal insert 20 can be inserted into the polygonal sleeve 19, the lower opening of the polygonal sleeve 19 is provided with multiple elastic strips 22, the outer periphery of the polygonal insert 20 is provided with multiple positioning recesses 23 corresponding to the elastic strips 22, the side of the elastic strip 22 near the center of the polygonal sleeve 19 is provided with a positioning protrusion 24, when the polygonal insert 20 is inserted into the polygonal sleeve 19, the positioning protrusion 24 on the elastic strip 22 can enter the corresponding positioning recess 23. With the above structure, after the rotating part 2 is connected to the mounting base 15, the polygonal insert 20 and the polygonal sleeve 19 cooperate to prevent relative rotation between the two. By controlling the rotating part 2, the rotation angle of the rotating part 2 can be accurately controlled. After the polygonal insert 20 is inserted into the polygonal sleeve 19, the positioning protrusion 24 can enter the positioning recess 23, so that the rotating part 2 and the mounting base 15 are kept together. By setting the connecting handle 21 at the upper opening of the polygonal sleeve 19, the installation and disassembly of the rotating part 2 are convenient.

[0040] Referring to Figures 1 and 2, in some embodiments of this utility model, the rotating member 2 is provided with multiple tapping contacts 25 corresponding to the milk powder compartment 3. The tapping contacts 25 are located on the side of the milk powder compartment 3 away from the rotation center of the rotating member 2. The main body 1 is provided with a vibration motor 26. When the rotating member 2 rotates to any milk powder compartment 3 at the set powder dispensing position, the contact of the vibration motor 26 can contact the tapping contact 25 corresponding to that milk powder compartment 3. With the above structure, when the milk powder compartment 3 dispenses milk powder as the rotating member 2 rotates to the set position, the contact of the vibration motor 26 can continuously tap the tapping contact 25 corresponding to that milk powder compartment 3 to promote the falling of milk powder in the compartment.

[0041] Referring to Figure 1, in some embodiments of this utility model, an automatic milk maker is also disclosed. The automatic milk maker includes the milk powder dispensing device described above. The bottom center of the mounting base 15 is provided with a power connection part 16 for connecting the output end of the power device 27. The main body 1 is equipped with the power device 27, and the power output end of the power device 27 is connected to the power connection part 16.

[0042] In the illustrated embodiment, the power device 27 is an electric motor, and the power engagement part 16 is a semi-circular hole provided on the mounting base 15. The end of the electric motor's power output shaft is a semi-cylinder that fits into the semi-circular hole, and the semi-cylinder is inserted into the semi-circular hole. In other embodiments of this utility model, the power device 27 can also be other devices capable of outputting rotation, and the power engagement part 16 can also be a spline hole or other structures. With the above structure, the power device 27 can output power to drive the mounting base 15 to rotate. The mounting base 15 drives the rotating part 2 to rotate, so that different milk powder compartments 3 reach the set powder dispensing position and open the bottom cover 5 of the milk powder compartment, realizing multiple milk powder dispensing. In conjunction with the water supply and mixing device on the automatic milk maker, multiple milk preparations can be achieved.

[0043] In a preferred embodiment of this invention, the part of the powder container bottom cover 5 used to block the powder outlet 4 (in the illustrated embodiment, the blocking part 9 is the part used to block the powder outlet 4) and the opening trigger part of the powder container bottom cover 5 (in the illustrated embodiment, the part where the first contact block 12 is located is the opening trigger part of the powder container bottom cover 5) are located on the same side of the rotating connection of the powder container bottom cover 5. When the rotating part 2 rotates to bring the powder container close to the bottle, the powder container bottom cover 5 is opened from the side that first enters the bottle opening, which reduces powder spillage and increases powder dispensing efficiency.
