Technical Field
[0001] This utility model relates to the field of beverage preparation equipment technology, specifically to an automatic milk maker. Background Technology
[0002] Newborns require frequent nighttime feedings, necessitating multiple preparations of formula by caregivers. The process involves taking a specific amount of formula from the container, adding hot water, and shaking repeatedly to mix the powder and water. This process is not only time-consuming but also disrupts the caregiver's sleep. Therefore, automatic formula makers have been developed.
[0003] Patent document CN218552085U discloses a milk powder preparer (i.e., an automatic milk powder maker) capable of automatically preparing milk powder. The milk powder preparer includes: a main body, a water tank, a shaking component, and a powder container assembly, which is located within a receiving slot. The powder container assembly includes an outer shell, an inner shell, and a driving component. The inner shell is located within the outer shell and its interior is divided into at least two chambers for holding milk powder. The lower part of the inner shell has a powder outlet corresponding to and communicating with the at least two chambers, and a sealing component is provided at the powder outlet. The bottom of the outer shell has an outlet directly facing the bottle opening. The driving component is located within the receiving slot and passes through the outer shell, connecting to the inner shell. When the driving component drives the inner shell to rotate within the outer shell, the sealing component is opened, and the powder outlet rotates to align with the outlet, allowing the milk powder in the chamber to fall into the bottle. In use, the milk powder is pre-added into different chambers of the powder box assembly, and then the powder box assembly is placed in the receiving slot. Then, the inner shell is driven by the drive unit to rotate within the outer shell, causing the sealing piece used to block the powder outlet to be protruded and pushed open. When the powder outlet rotates to be aligned with the outlet, the milk powder placed in the chamber enters the bottle through the powder outlet and outlet, thus completing one dispensing of milk powder. Then, the water pump introduces water from the water tank into the bottle, thereby completing the automatic preparation of the milk powder.
[0004] The above-mentioned formula maker has the following problems during use:
[0005] 1. Powder spillage: To facilitate the handling of the bottle and avoid interference between the outer shell and the bottle, the bottle opening needs to maintain a certain distance from the outlet on the outer shell. This design causes the milk powder to easily spill outside the bottle during the fall, which not only wastes the milk powder but also causes it to stick to the bottle, the formula mixer, and even the table, making it difficult to clean.
[0006] 2. Powder jamming problem: The powder box assembly includes an outer shell and an inner shell. The chamber for holding the milk powder is located on the inner shell, and the inner shell has an outlet for communicating with the chamber. When dispensing powder, the milk powder can easily drift into the gap between the outer shell and the inner shell. When the inner shell rotates, residual powder can also enter the gap between the outer shell and the inner shell, causing powder jamming.
[0007] 3. Powder sticking at the outlet: The milk powder in each independent chamber needs to fall into the bottle through a common outlet. The common outlet is prone to milk powder sticking, which can easily become damp, clump, or even spoil, affecting the health of the drinker.
[0008] This invention improves the automatic formula maker and addresses the technical contradictions in the prior art: if the bottle is far from the formula container, the formula will easily spill outside the bottle during dispensing; if the bottle is close to the formula container, it will be difficult to pick up and put down the bottle. Utility Model Content
[0009] The purpose of this invention is to provide an automatic formula maker that solves the technical contradictions in the prior art: if the bottle is far from the formula container, the formula will easily spill outside the bottle when it is dispensed; if the bottle is close to the formula container, it will be difficult to pick up and put down the bottle.
[0010] To achieve the above objectives, this utility model provides an automatic formula maker, including a main body. The main body is equipped with a water storage device, a water injection device, a formula dispensing device, and a mixing module. The mixing module is used to hold a baby bottle and mix the milk in the bottle by shaking or vibrating it. The water storage device is used to store water. The water injection device is used to draw water from the water storage device and inject it into the baby bottle placed on the mixing module. The formula dispensing device is used to dispense formula into the baby bottle placed on the mixing module. The formula dispensing device includes a rotating component rotatably mounted on the main body. The main body is equipped with a rotating component drive device for driving the rotating component to rotate. Multiple formula containers are arranged around the rotation center of the rotating component, and the bottom of each formula container has a powder outlet. The mixing module is lower than the rotating component and the formula containers. When the rotating component rotates, the powder outlet of any formula container can be opened. Facing the mixing module; the milk powder compartment or rotating part has an opening and closing bottom cover corresponding to the milk powder compartment, which controls the opening and closing of the milk powder inlet; the water injection device includes a water injection pipe installed on the main body, the water injection pipe has a water injection port, which is used to inject water into the bottle, the water injection pipe is located below the rotating part, and the water injection pipe is installed on the main body in a telescopic or swinging manner so that it has two working states: close to and away from the mixing module; the main body is provided with a water injection pipe drive device for driving the water injection pipe to telescopic or swing to change the working state of the water injection pipe; the main body is provided with a milk powder compartment opening trigger mechanism or milk powder compartment opening trigger part, which is used to trigger the opening of the bottom cover of the milk powder compartment corresponding to the milk powder compartment when the rotating part rotates to a position where a milk powder compartment is facing the mixing module. A mixing module lifting device is provided between the mixing module and the main body. The mixing module lifting device is used to adjust the height of the mixing module so that the mixing module is closer to or further away from the milk powder compartment.
[0011] This automatic formula maker simplifies the formula preparation process by automatically dispensing water, formula, and mixing the formula. The formula dispensing device has multiple compartments to hold multiple servings, allowing for multiple preparations. Each compartment is independent, dispensing formula through its own inlet. The inlet and main unit are seamlessly connected, preventing powder buildup and sticking at common outlets. The mixing module features a lifting mechanism that allows it to move up and down. When the module is raised, the bottle is closer to the inlet, eliminating powder spillage during dispensing. When the module is lowered, the bottle is removed from the compartments for easy removal.
[0012] Furthermore, the water storage device includes a water tank and a supporting base. The supporting base is connected to the main body, and the water tank can be placed and removed from the supporting base. A coupler is provided between the water tank and the supporting base. An electric heating device is provided on the water tank, and a connecting valve is provided at the bottom of the water tank. A connecting pipe for connecting to the water injection device is provided on the supporting base. The coupler is used to connect the electric heating device to the power supply introduced into the supporting base when the water tank is placed on the supporting base. When the water tank is placed on the supporting base, the upper end of the connecting pipe can trigger the connecting valve to open, thereby connecting the connecting pipe to the water tank. Through the improvement of the water storage device, the water tank can be automatically heated and the water injection device can be automatically connected after the user puts it in, which facilitates the smooth progress of subsequent brewing, and there is no leakage when the water tank is removed.
[0013] Furthermore, the water injection pipe is located below the rotating component. The water injection pipe is installed on the main body in a way that allows it to extend or swing, thus enabling it to have two working states: close to and far from the mixing module. The main body is provided with a water injection pipe driving device for driving the water injection pipe to extend or swing to change the working state of the water injection pipe.
[0014] Furthermore, the water injection device also includes a water pump with an inlet and an outlet. The inlet is connected to a water storage device via a pipe, and the outlet is connected to a water injection pipe via a pipe. Through these improvements to the water injection device, the water injection pipe is located below the milk powder compartment and can extend, retract, or swing. This ensures that the water injection pipe does not interfere with the bottle when dispensing milk powder, allowing the bottle to be closer to the powder inlet and further improving the problem of powder spillage.
[0015] Furthermore, the mixing module includes a mixing module base, on which a bottle holder capable of rotating around a vertical axis is mounted. The mixing module base is equipped with a bottle holder drive device for driving the bottle holder to rotate forward and / or in the reverse direction. The bottle holder drive device drives the bottle holder to rotate in both directions, thus achieving the mixing of the milk, and the mixing process is relatively stable.
[0016] Furthermore, the mixing module lifting device includes a first transmission component rotatably mounted on the main body and a driving component for driving the first transmission component to rotate. The mixing module itself or through a second transmission component connected to it is in transmission engagement with the first transmission component. The transmission engagement method is threaded engagement or gear and rack engagement. The main body is provided with a limiting structure for constraining the mixing module so that it can only move in the vertical direction. The limiting structure allows the mixing module to move only vertically. The driving component drives the first transmission component to rotate. Under the transmission engagement of the first transmission component and the second transmission component or the mixing module, the mixing module rises or falls, thereby adjusting the height of the baby bottle placed on the mixing module. When the baby bottle is raised, the bottle mouth is closer to the powder inlet, which can prevent powder from floating. When the baby bottle is lowered, it is a certain distance away from the powder inlet, making it convenient to remove the baby bottle from the mixing module.
[0017] Furthermore, the first transmission component is a threaded sleeve or a lead screw. When the first transmission component is a threaded sleeve, the mixing module extends into the threaded sleeve and is threadedly engaged with it. When the first transmission component is a lead screw, a nut threadedly engaged with the lead screw is fixedly connected to the mixing module. The driving component is a mixing module lifting motor mounted on the main body to drive the first transmission component to rotate. The limiting structure includes a sliding connection mechanism between the main body and the mixing module. Since the mixing module cannot rotate, and the first transmission component is a threaded sleeve or a lead screw, when the first transmission component is a threaded sleeve, the mixing module extends into the threaded sleeve and is threadedly engaged with it; when the first transmission component is a lead screw, a nut threadedly engaged with the lead screw is fixedly connected to the mixing module. Therefore, when the mixing module lifting motor drives the first transmission component to rotate, the mixing module can be lifted and lowered. This mixing module lifting device is simple, stable, and easy to control.
[0018] Furthermore, a rotating connector is rotatably mounted on the main body, and the rotating component is detachably connected to the rotating connector. The rotating component's drive device is poweredly connected to the rotating connector. In this way, the rotating component and the milk powder container can be detached from the main body for easy cleaning.
[0019] Furthermore, the rotating component and the milk powder container are separate structures, with the milk powder container detachably mounted on the rotating component. This allows the milk powder container to be removed from the rotating component for easy cleaning.
[0020] Furthermore, multiple milk powder compartment bottom covers are arranged around the rotating component, and the bottom covers are rotatably connected to the rotating component in a manner that allows them to swing horizontally relative to the powder dispensing port. With the above structure, all milk powder compartment bottom covers are uniformly arranged on the rotating component, and the position of all the bottom covers is based on the rotating component, which facilitates installation and ensures more accurate working position.
[0021] Furthermore, the milk powder compartment opening trigger mechanism includes a trigger block vertically floating on the main body. An elastic buffer element is provided between the trigger block and the main body, and an elastic reset element is provided between the milk powder compartment bottom cover and the rotating component. When the rotating component rotates to a position where a milk powder compartment is directly opposite the mixing module, the trigger block contacts the bottom cover of that milk powder compartment, causing it to rotate and open. When the rotating component continues to rotate a set angle, the bottom cover of the milk powder compartment can pass over the trigger block, and the elastic reset element can reset the bottom cover. With the above structure, when the rotating component rotates to a set position, the trigger block can trigger the opening of the bottom cover of the milk powder compartment. When the rotating component continues to rotate a set angle, the bottom cover of the milk powder compartment can cause the trigger block to slide downwards against the force of the elastic buffer element, thus passing over the trigger block. Subsequently, the elastic reset element can cause the bottom cover of the milk powder compartment to swing back to its original position.
[0022] Furthermore, the bottom cover of the milk powder compartment is rotatably connected to the milk powder compartment in a manner that allows it to swing horizontally relative to the powder inlet. The milk powder compartment opening trigger mechanism includes a body limiting protrusion on the main body. When the rotating component rotates to a position where a milk powder compartment is close to or directly facing the mixing module, the body limiting protrusion contacts the bottom cover of the milk powder compartment, causing the bottom cover to rotate and open. This opening method has a simple structure and ensures that the bottom cover of the milk powder compartment will only open when the milk powder compartment reaches the position above the bottle, making it less likely to spill powder and reducing errors caused by improper operation.
[0023] Furthermore, the portion of the milk powder compartment bottom cover that is away from the powder inlet and close to the rotation center of the rotating component is rotatably connected to the milk powder compartment via a rotating shaft. The milk powder compartment bottom cover is provided with a compartment cover limiting contact for contacting the limiting protrusion of the machine body. The compartment cover limiting contact is located between the rotating shaft and the powder inlet. When the rotating component rotates to the point where one of the milk powder compartments enters the bottle opening on the mixing module, the limiting protrusion of the machine body contacts the compartment cover limiting contact. As the rotating component continues to rotate, the milk powder compartment bottom cover gradually opens from the side where the powder inlet first enters the bottle opening. The powder inlet opens wider and wider from the side where it enters the bottle opening, which not only improves the efficiency of powder dispensing but also prevents milk powder from spilling outside the bottle.
[0024] Furthermore, the bottom cover of the milk powder compartment is hinged to the milk powder compartment in a manner that allows it to flip downwards relative to the powder inlet. A swing arm is installed on the milk powder compartment, with its middle section hinged to the compartment. The lower end of the swing arm has a pawl for hooking the free side of the bottom cover to keep it closed. A sliding rod is provided on the rotating component for each milk powder compartment, with one end of the rod facing the upper end of the swing arm. The milk powder compartment opening trigger mechanism includes a body limiting cam on the main body. When the rotating component rotates to the position where the milk powder compartment is directly opposite the mixing module, the body limiting cam activates the sliding rod corresponding to that compartment. The sliding rod pushes the upper end of the swing arm, disengaging the pawl from the bottom cover and thus opening the bottom cover. This opening method prevents milk powder from spilling, ensuring the powder falls precisely into the bottle. Opening is achieved simply by rotating the component, reducing the use of electrical components and resulting in a low defect rate.
[0025] Furthermore, the bottom cover of the milk powder compartment is hinged to the milk powder compartment in a manner that allows it to flip downwards relative to the powder inlet. A swing arm is installed on the milk powder compartment, with its middle section hinged to the compartment. The lower end of the swing arm has a hook for engaging the free side of the bottom cover to keep it closed. The milk powder compartment opening trigger mechanism includes a power component on the main body capable of outputting linear motion. When the rotating component rotates to a position where the milk powder compartment is directly opposite the mixing module, the power output end of the power component pushes the upper end of the swing arm, causing the hook to disengage from the bottom cover. This opening method is easy to design and control.
[0026] Furthermore, the main body is equipped with a powder receiving tray and a tapping device. The tapping device is used to tap the powder container when the rotating part rotates to a position that moves the powder container away from the bottle, causing any remaining powder in the container to fall onto the receiving tray. After the powder is dispensed, the tapping device ensures that any remaining powder falls onto the receiving tray, preventing it from spilling onto other parts of the main body.
[0027] Furthermore, the rotating component is provided with multiple positioning blocks corresponding to the milk powder compartment, and the main body is provided with a limit switch. The limit switch is connected to the controller of the automatic milk maker. When the rotating component rotates, the milk powder inlet of any milk powder compartment is aligned with the mixing module. When the positioning block touches the contact of the limit switch, it sends a signal to the controller, which is beneficial for realizing the position control of the rotating component.
[0028] Furthermore, the main body is equipped with a sensor capable of detecting the position of the baby bottle. The sensor is electrically connected to the controller of the automatic milk maker, which facilitates the control of the lifting and lowering height of the baby bottle.
[0029] In summary, the beneficial effects of this utility model are as follows: 1. This utility model is applicable to the preparation of milk powder, not only realizing the functions of automatic hot water, automatic water injection, and automatic milk powder dispensing, but also automatically mixing milk powder and water, greatly simplifying the preparation process. 2. The rotating component of this utility model has multiple milk powder compartments around its rotation center. The rotation of the rotating component can not only bring different milk powder compartments to the top of the mixing module, but also trigger the automatic opening of the bottom cover of the corresponding milk powder compartment, thereby completing the quantitative dispensing of milk powder, and is suitable for application scenarios of multiple milk powder preparations. 3. This invention incorporates a mixing module lifting device between the mixing module and the main body. When the mixing module rises, it brings the bottle opening closer to the milk powder inlet of the working milk powder hopper, preventing milk powder from spilling outside the bottle during dispensing. When the mixing module lowers, it moves the bottle away from the milk powder hopper, ensuring unobstructed bottle handling. This solves the technical problems of existing technologies where milk powder spills when the bottle is too close to the hopper, or is difficult to handle when the bottle is too far away. Furthermore, by incorporating multiple milk powder hoppers and a bottom cover on the rotating component, it solves the problems of powder jamming and powder sticking to the common outlet in existing technologies. 4. This invention achieves residual powder cleaning after dispensing by incorporating a powder receiving tray and a tapping device, helping to maintain the cleanliness of the automatic formula maker. 5. Water is added during the rising of the mixing module, and the water-addition mixing module descends simultaneously with the mixing module's operation, maximizing time savings and enabling rapid formula preparation. 6. After adding the milk powder, move the milk powder container away from the center of the mixing module. This keeps the milk powder container away from the bottle opening where the mixing module is placed, reducing the chance of the milk powder absorbing heat and becoming damp. The milk powder container is cleaner and easier to clean. Attached Figure Description

[0052] In order to achieve the lifting and lowering of the mixing module 5, this utility model has also made several improvements.
[0053] Reference Figure 3 , Figure 9 , Figure 10 In some embodiments of this utility model, the mixing module lifting device 12 includes a first transmission component 30 rotatably mounted on the main body 1 and a driving component for driving the first transmission component 30 to rotate. The mixing module 5 itself or through a second transmission component connected thereto is in transmission cooperation with the first transmission component 30. The transmission cooperation method is threaded cooperation or gear rack cooperation. The main body 1 is provided with a limiting structure for constraining the mixing module 5 so that it can only move in the up and down direction.
[0054] exist Figure 3 In the illustrated embodiment, the first transmission component 30 is a lead screw, and the second transmission component is a nut connected to the mixing module 5. The lead screw and nut are threaded together. The driving component is a mixing module lifting motor 31 mounted on the main body 1 to drive the lead screw to rotate. The limiting structure includes a groove on the main body 1, through which the portion of the nut near the mixing module 5 passes, thereby constraining the mixing module 5 so that it can only move in the vertical direction. During operation, the mixing module lifting motor 31 drives the lead screw to rotate. Under the action of the lead screw and nut, the nut moves up and down, thereby driving the mixing module 5 to rise and fall.

The outer circumferential surface of the mixing module 5 is provided with an external thread, which engages with the internal thread on the threaded sleeve. The driving component is a mixing module lifting motor 31 mounted on the main body 1 to drive the threaded sleeve to rotate. The limiting structure includes two guide grooves on the main body 1, and two guide blocks connected to the mixing module 5. Each guide block is inserted into a guide groove, thereby constraining the mixing module 5 so that it can only move in the vertical direction. During operation, the mixing module lifting motor 31 outputs power, which, after gear transmission, causes the threaded sleeve to rotate. Under the threaded engagement between the threaded sleeve and the mixing module 5, the mixing module 5 is driven to rise and fall.
[0056] In another embodiment of this utility model (not shown in the figure), the first transmission component 30 is a gear, and the second transmission component is a rack connected to the mixing module 5.

During operation, the mixing module lifting motor 31 outputs power, and under the meshing action of the gear and rack, the rack rises and falls, driving the mixing module 5 to rise and fall.
[0057] In some other embodiments of this utility model, the mixing module lifting device 12 may also adopt other structures in the prior art, such as a fork-scissor type lifting drive mechanism, a chain traction type lifting drive mechanism, etc.
[0058] To facilitate the cleaning of the milk powder container 8, this utility model has also made several improvements.
[0059] In some embodiments of this utility model, a rotating connector is rotatably mounted on the main body 1, and a rotating component 6 is detachably connected to the rotating connector.

[0061] In order to better achieve the automatic opening of the bottom cover 10 of the milk powder compartment, this utility model has also made several improvements.
[0062] Reference Figure 11 , Figure 12 , Figure 13 In some embodiments of this utility model, multiple milk powder compartment bottom covers 10 are arranged around the rotating member 6, and the milk powder compartment bottom covers 10 are rotatably connected to the rotating member 6 in a manner that allows them to swing horizontally relative to the powder dispensing port 9. The powder dispensing port 9 can be opened or closed by swinging the milk powder compartment bottom covers 10 horizontally. With the above structure, all milk powder compartment bottom covers 10 are uniformly arranged on the rotating member 6, and the position of all milk powder compartment bottom covers 10 is based on the rotating member 6, which facilitates installation and ensures relatively accurate working positions. The milk powder compartment opening trigger mechanism includes a trigger block 43 vertically floating on the main body 1. An elastic buffer element 44 is provided between the trigger block 43 and the main body 1, and an elastic reset element 45 is provided between the milk powder compartment bottom cover 10 and the rotating component 6. When the rotating component 6 rotates to a position where the milk powder compartment 8 is directly opposite the mixing module 5, the trigger block 43 contacts the milk powder compartment bottom cover 10 corresponding to that milk powder compartment 8, causing it to rotate and open. When the rotating component 6 continues to rotate a set angle, the milk powder compartment bottom cover 10 can pass over the trigger block 43, and the elastic reset element 45 can reset the milk powder compartment bottom cover 10. The trigger block 43 being vertically floating on the main body 1 means that it is mounted on the main body 1 and can float up and down relative to the main body 1. For example… Figure 13In the illustrated embodiment, the trigger block 43 has a base plate at its bottom with two guide holes on the left and right sides. The main body 1 has two guide posts, each passing through a guide hole. Under the combined action of the guide holes and guide posts, the base plate and trigger block 43 can float up and down. Limit screws are installed on the top surface of the guide posts. In this embodiment, the trigger block 43 has a wedge-shaped surface at its top. The milk powder compartment bottom cover 10 has a passive contact block, and the bottom of the passive contact block also has a wedge-shaped surface. The two wedge-shaped surfaces can cooperate with each other. During the contact process, the milk powder compartment bottom cover 10 is first triggered to open, and then the milk powder compartment bottom cover 10 presses down on the trigger block 43, allowing the milk powder compartment bottom cover 10 to pass over the trigger block 43. Figure 13 In the illustrated embodiment, the elastic buffer element 44 is a spring disposed between the trigger block 43 and the main body 1. The lower end of the spring contacts the main body 1, and the upper end of the spring contacts the trigger block 43. Figure 12 In the illustrated embodiment, the elastic reset element 45 is a torsion spring disposed between the milk powder compartment bottom cover 10 and the rotating component 6. The milk powder compartment bottom cover 10 is connected to the rotating component 6 via a vertical pivot, thereby enabling the milk powder compartment bottom cover 10 to swing horizontally relative to the rotating component 6. The torsion spring is mounted on the vertical pivot, and its two torsion arms rest on the milk powder compartment bottom cover 10 and the rotating component 6, respectively. The force of the torsion spring causes the milk powder compartment bottom cover 10 to automatically reset. When the rotating component 6 rotates to a set position, the trigger block 43 can trigger the milk powder compartment bottom cover 10 to open. When the rotating component 6 continues to rotate at a set angle, the milk powder compartment bottom cover 10 can cause the trigger block 43 to slide downward against the force of the elastic buffer element 44, thereby passing over the trigger block 43. Subsequently, the elastic reset element 45 can cause the milk powder compartment bottom cover 10 to swing back to its original position.
[0063] Reference Figure 3 In one embodiment of this utility model, the bottom cover 10 of the milk powder compartment is rotatably connected to the milk powder compartment 8 in a manner that allows it to swing horizontally relative to the powder inlet 9. The powder inlet 9 can be opened or closed by swinging the bottom cover 10 horizontally. The milk powder compartment opening trigger includes a body limiting protrusion 32 provided on the main body 1. When the rotating member 6 rotates to a position where the milk powder compartment 8 is close to or directly facing the mixing module 5, the body limiting protrusion 32 contacts the bottom cover 10 of the milk powder compartment, causing the bottom cover 10 to rotate and open.
[0064] Reference Figure 5 , Figure 6 In the illustrated embodiment, the part of the milk powder compartment bottom cover 10 that is far from the powder outlet 9 and close to the rotation center of the rotating component 6 is rotatably connected to the milk powder compartment 8 via a rotating shaft 42. The milk powder compartment bottom cover 10 is provided with a compartment cover limiting contact 41 for contacting the body limiting protrusion 32. The compartment cover limiting contact 41 is located between the rotating shaft 42 and the powder outlet 9.
[0065] Reference Figure 7In another embodiment of this utility model, the bottom cover 10 of the milk powder compartment is hinged to the milk powder compartment 8 in a manner that allows it to flip downward relative to the powder inlet 9. A swing arm 33 is installed on the milk powder compartment 8, with the middle part of the swing arm 33 hinged to the milk powder compartment 8. The lower end of the swing arm 33 is provided with a hook 34 for hooking the free side of the bottom cover 10 of the milk powder compartment to keep the bottom cover 10 of the milk powder compartment closed. A sliding rod 35 is provided on the rotating part 6 for each milk powder compartment 8, with one end of the sliding rod 35 facing the upper end of the swing arm 33. The milk powder compartment opening trigger mechanism includes a body limiting cam 36 provided on the main body 1. When the rotating part 6 rotates to the position where the milk powder compartment 8 is directly facing the mixing module 5, the body limiting cam 36 touches the sliding rod 35 corresponding to the milk powder compartment 8. The sliding rod 35 pushes the upper end of the swing arm 33, and the hook 34 disengages from the bottom cover 10 of the milk powder compartment, thereby opening the bottom cover 10 of the milk powder compartment.
[0066] Reference Figure 8 In another embodiment of this utility model, the bottom cover 10 of the milk powder compartment is hinged to the milk powder compartment 8 in such a way that it can be flipped downward relative to the powder outlet 9. A swing arm 33 is installed on the milk powder compartment 8. The middle part of the swing arm 33 is hinged to the milk powder compartment 8. The lower end of the swing arm 33 is provided with a hook 34 for hooking the free side of the bottom cover 10 of the milk powder compartment to keep the bottom cover 10 of the milk powder compartment closed. The milk powder compartment opening trigger mechanism includes a power component 37 provided on the main body 1 that can output linear motion. When the rotating component 6 rotates to the position where the milk powder compartment 8 is facing the mixing module 5, the power output end of the power component 37 pushes the upper end of the swing arm 33 to disengage the hook 34 from the bottom cover 10 of the milk powder compartment.
[0067] In order to clean the residual powder in the milk powder compartment 8, Figure 4 In the embodiment shown, the main body 1 is provided with a powder receiving tray 38 and a tapping device 39. The tapping device 39 is used to tap the powder container 8 when the rotating part 6 rotates to a position that moves the powder container 8 away from the bottle, so that the residual powder in the container falls onto the powder receiving tray 38.
[0068] The rotating part 6 is equipped with multiple positioning blocks 46 corresponding to the milk powder compartment 8. The main body 1 is equipped with a limit switch 47, which is connected to the controller of the automatic milk maker. When the rotating part 6 rotates, the powder outlet 9 of any milk powder compartment 8 is aligned with the mixing module 5. When the positioning block 46 touches the contact of the limit switch 47, it sends a signal to the controller.
[0069] In some embodiments of this utility model, the main body 1 is provided with a sensor that can detect the position of the baby bottle. The sensor is electrically connected to the controller of the automatic milk maker and can output a signal to the controller.
