Description

An automatic milk maker and its control method Technical Field

[0001] This invention relates to the field of beverage preparation equipment technology, specifically to an automatic milk maker and its control method. 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 were invented.

[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 addresses the technical contradictions in existing technologies by improving automatic formula makers. 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. Summary of the Invention

[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, the present invention provides an automatic formula maker, comprising a main body, a water storage device, a water injection device, a formula powder 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 powder dispensing device is used to dispense formula powder into the baby bottle placed on the mixing module. The formula powder dispensing device includes a rotating component rotatably mounted on the main body. The main body is provided with a rotating component drive device for driving the rotating component to rotate. The rotating component has multiple formula powder compartments arranged around its rotation center. The bottom of each formula powder compartment has a powder discharge port. The mixing module is lower than the rotating component and the formula powder compartments. When the rotating component rotates, it can ensure that the powder discharge port of any formula powder compartment is aligned with the rotating component. For the mixing module; the milk powder compartment or rotating part is provided with a milk powder compartment bottom cover that can be opened and closed, and the opening and closing of the milk powder compartment bottom cover is used to control the opening and closing of the powder dispensing port; the water injection device includes a water injection pipe installed on the main body, the water injection pipe has a water injection port, the water injection port is used to inject water into the bottle through it, 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 milk powder compartment bottom cover corresponding to the milk powder compartment when the rotating part rotates to a position where a milk powder compartment is directly 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. There are no dead angles between the inlet and the main body, preventing formula clogging and sticking at the common outlet. The invention incorporates a lifting mechanism for the mixing module. When the module rises, the bottle is closer to the inlet, solving the problem of powder spillage during dispensing. When the module descends, the bottle is removed from the compartments, facilitating 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 can be automatically heated and the water injection device can be automatically connected after the user puts the water tank 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 has multiple positioning blocks corresponding to the milk powder compartments, and the main body is equipped with limit switches connected to the controller of the automatic milk maker. When the rotating component rotates, it ensures that the powder dispensing port of any milk powder compartment is directly aligned with the mixing module. The positioning blocks then trigger the contacts of the limit switches, sending a signal to the controller, which stops the rotating component from rotating. This allows the milk powder compartments to stop dispensing powder, preventing milk powder from spilling outside the bottle.

[0028] Furthermore, the main body is equipped with a sensor capable of detecting the position of the baby bottles. The sensor is connected to the controller of the formula maker. The controller controls the lifting device of the mixing module based on the detection signal from the sensor. When the mixing module is lifted by the lifting device, baby bottles of different heights can approach the powder inlet. This allows the automatic formula maker to adapt to baby bottles of different heights without spilling or scattering powder.

[0029] Furthermore, the automatic milk maker also includes a control system, which includes a controller. A water injection device, a milk powder dispensing device, a mixing module, and a mixing module lifting device are all electrically connected to the controller. The controller has a first control module, a second control module, and a third control module. The first control module is configured to: control the mixing module lifting device to raise the mixing module; control the water injection device to inject water during the raising of the mixing module; the second control module is configured to: after the mixing module has risen a set distance, control the milk powder dispensing device to rotate the rotating component so that the powder inlet of one of the milk powder compartments is close to or directly facing the mixing module, opening the bottom cover of the milk powder compartment to dispense milk powder; the third control module is configured to: control the mixing module lifting device to lower the mixing module; control the mixing module to operate; and control the mixing module to start at any stage of raising the mixing module, opening the bottom cover of the milk powder compartment, or lowering the mixing module. After the above improvements, the bottom cover of the milk powder compartment can be opened after the mixing module rises, so that the bottle mouth placed on the mixing module is close to the powder drop outlet of the milk powder compartment, which can prevent powder from floating to the greatest extent. Water is added during the rising of the mixing module, and the water-filling mixing module descends at the same time as the mixing module works, which can save working time to the greatest extent and realize rapid milk preparation.

[0030] Furthermore, the second control module is also configured to: after the milk powder in the milk powder container is dispensed, control the milk powder dispensing device to rotate the rotating component by a set angle, so that the milk powder container moves away from the center of the mixing module. After the above improvement, by moving the milk powder container away from the center of the mixing module, the milk powder container can be kept away from the bottle opening where the mixing module is placed, reducing the chance of the milk powder absorbing heat and becoming damp, making the milk powder container cleaner and easier to clean.

[0031] This invention also discloses a control method for an automatic milk maker, applied to the aforementioned automatic milk maker. The control method includes the following steps: Step S100: Controlling the lifting device of the mixing module to raise the mixing module, and controlling the water injection device to inject water during the raising of the mixing module; Step S200: After the mixing module has risen a set distance, controlling the milk powder dispensing device to rotate the rotating part so that the powder dispensing port of one of the milk powder compartments is close to or directly facing the mixing module, and opening the bottom cover of the milk powder compartment to dispensing milk powder from the milk powder compartment; Step S300: Controlling the lifting device of the mixing module to lower the mixing module; controlling the operation of the mixing module at any stage of steps S100, S200, and S300. After the above improvements, the bottom cover of the milk powder compartment can be opened after the mixing module rises, so that the bottle mouth placed on the mixing module is close to the powder drop outlet of the milk powder compartment, which can prevent powder from floating to the greatest extent. Water is added during the rising of the mixing module, and the water-filling mixing module descends at the same time as the mixing module works, which can save working time to the greatest extent and realize rapid milk preparation.

[0032] Furthermore, step S200 also includes: after the milk powder in the milk powder container is dispensed, controlling the milk powder dispensing device to rotate the rotating component by a set angle, so that the milk powder container moves away from the center of the mixing module. After the above improvement, by moving the milk powder container away from the center of the mixing module, the milk powder container can be kept away from the bottle opening where the mixing module is placed, reducing the chance of the milk powder absorbing heat and becoming damp, making the milk powder container cleaner and easier to clean.

[0033] In summary, the beneficial effects of this invention are as follows: 1. This invention 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 invention has multiple milk powder compartments arranged around its rotation center. The rotation of the rotating component can not only bring different milk powder compartments above 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 compartment, preventing milk powder from spilling outside the bottle during dispensing. When the mixing module lowers, it moves the bottle away from the milk powder compartment, ensuring unobstructed bottle handling. This solves the technical problems of existing technologies where milk powder spills when the bottle is too close to the compartment, or is difficult to handle when the bottle is too far away. Furthermore, by incorporating multiple milk powder compartments 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 uses a powder receiving tray and a tapping device to clean residual powder after dispensing, 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

[0051] 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.

[0052] This invention provides an automatic milk powder preparation machine, which aims to realize the automatic preparation of milk powder and solve the problems of powder spillage, powder jamming, and powder sticking at the public outlet of existing automatic milk powder preparation machines.

[0053] Referring to Figures 1 to 4, in one embodiment of the present invention, the automatic formula maker includes a main body 1. The main body 1 is provided with a water storage device 2, a water injection device 3, a milk powder dispensing device 4, and a mixing module 5. The mixing module 5 is used to place a baby bottle 40 and mix the milk in the bottle by shaking or vibrating the baby bottle 40. The water storage device 2 is used to store water. The water injection device 3 is used to draw water from the water storage device 2 and inject it into the baby bottle 40 placed on the mixing module 5. The milk powder dispensing device 4 is used to dispense milk powder into the baby bottle 40 placed on the mixing module 5. The milk powder dispensing device 4 includes a rotating component 6 rotatably mounted on the main body 1. The main body 1 is provided with a rotating component drive device 7 for driving the rotating component 6 to rotate. The rotating component 6 has multiple milk powder compartments 8 around its rotation center. The bottom of the milk powder compartment 8 has a powder outlet 9.

The water injection device 3 includes a water injection pipe 20 mounted on the main body 1. The water injection pipe 20 has a water injection port 22 for injecting water into the bottle. The water injection pipe 20 is located below the rotating component 6. The water injection pipe 20 is mounted on the main body 1 in a swinging manner, allowing it to have two working states: close to and away from the mixing module 5. The main body 1 is provided with a water injection pipe drive device for driving the water injection pipe 20 to swing and change its working state. A mixing module lifting device 12 is provided between the mixing module 5 and the main body 1. The mixing module lifting device 12 is used to adjust the height of the mixing module 5, allowing the mixing module 5 to move closer to or further away from the milk powder compartment 8.

[0054] Figures 3 and 16 illustrate one structure of the water storage device 2. The water storage device 2 includes a water tank 13 and a support base 14. The support base 14 is connected to the main body 1. The water tank 13 can be placed on and removed from the support base 14. A coupler 15 is provided between the water tank 13 and the support base 14. An electric heating device 16 is provided on the water tank 13. A connecting valve 17 is provided at the bottom of the water tank 13. A connecting pipe 18 for connecting to the water injection device 3 is provided on the support base 14. The coupler 15 is used to connect the electric heating device 16 to the power supply introduced into the support base 14 when the water tank 13 is placed on the support base 14. When the water tank 13 is placed on the support base 14, the upper end of the connecting pipe 18 can trigger the connecting valve 17 to open, thereby connecting the connecting pipe 18 to the water tank 13. In other embodiments of the present invention, the water storage device 2 can also adopt other structural forms, for example: the water storage device 2 includes a water tank 13, an electric heating device 16 is provided on the water tank 13, and it is equipped with a socket for connecting to a power source. The water pump 19 of the water injection device 3 is installed inside the water tank 13, or water is drawn from the water tank 13 through a water pumping pipe. For example, the water storage device 2 includes a water tank 13 and a support base 14. The support base 14 is connected to the main body 1. The water tank 13 has a heat preservation function and can hold hot water.

[0055] Figure 3 illustrates one structure of the water injection device 3. The water injection device 3 also includes a water pump 19 installed on the main body 1. The water pump 19 has an inlet 23 and an outlet 24. The inlet 23 is connected to the water storage device 2 through a pipeline, and the outlet 24 is connected to the water injection pipe 20 through a pipeline.

[0056] In other embodiments of the present invention, the water injection device 3 may also adopt other structural forms. For example, in the embodiment shown in FIG8, the water injection pipe 20 is located below the rotating member 6, and the water injection is installed on the main body 1 in a telescopic manner so that it has two working states: close to and far from the mixing module 5. The main body 1 is provided with a water injection pipe driving device for driving the water injection pipe 20 to telescopically change the working state of the water injection pipe 20.

[0057] Figure 3 illustrates one structure of the mixing module 5. The mixing module 5 includes a mixing module base 27, on which a bottle holder 28 capable of rotating about a vertical axis is mounted. The mixing module base 27 is provided with a bottle holder drive device 29 for driving the bottle holder 28 to rotate forward and / or in the opposite direction. In other embodiments of the present invention, the mixing module 5 may also adopt other structures. For example, the mixing module 5 may include a mixing module base 27, on which a bottle holder 28 is provided, and a vibration motor for vibrating the bottle holder 28 is mounted on the mixing module base 27 or the bottle holder 28 to achieve mixing by vibration.

[0058] In order to achieve the lifting and lowering of the mixing module 5, the present invention has also made several improvements.

[0059] Referring to Figures 3, 9, and 10, in some embodiments of the present invention, 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 engagement with the first transmission component 30. The transmission engagement method is thread engagement or gear and rack engagement. 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.

[0060] In the embodiment shown in Figure 3, 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 part of the nut near the mixing module 5 passes, thereby constraining the mixing module 5 so that it can only move in the up-down 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.

[0061] In the embodiments shown in Figures 9 and 10, the first transmission component 30 is a threaded sleeve, and the mixing module 5 extends into the threaded sleeve. The outer circumferential surface of the mixing module 5 is provided with an external thread, and the external thread on the mixing module 5 and the internal thread on the threaded sleeve are threadedly engaged. 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 are 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.

[0062] In another embodiment of the present invention (not shown in the figures), the first transmission component 30 is a gear, and the second transmission component is a rack connected to the mixing module 5. The gear and rack mesh with each other. The driving component is a mixing module lifting motor 31 mounted on the main body 1 for driving the gear to rotate. The limiting structure includes a sliding connection mechanism between the main body 1 and 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.

[0063] In some other embodiments of the present invention, the mixing module lifting device 12 may also adopt other structures in the prior art, such as a fork-scissor lifting drive mechanism, a chain traction lifting drive mechanism, etc.

[0064] To facilitate the cleaning of the milk powder container 8, several improvements have been made to this invention.

[0065] In some embodiments of the present invention, a rotating connector is rotatably mounted on the main body 1, and a rotating component 6 is detachably connected to the rotating connector. A rotating component drive device 7 is poweredly connected to the rotating connector. The detachable connection method mentioned herein includes, but is not limited to, plug-in connection, threaded connection, etc.

[0066] In some embodiments of the present invention, the rotating component 6 and the milk powder container 8 are separate structures, and the milk powder container 8 is detachably mounted on the rotating component 6. The rotating component 6 may be provided with a milk powder container mounting hole or mounting part, and the milk powder container 8 is mounted at the mounting hole or mounting part. The detachable connection method mentioned herein includes, but is not limited to, plug-in connection, threaded connection, and snap-fit ​​connection.

[0067] To better achieve automatic opening of the milk powder compartment bottom cover 10, this invention has also made several improvements.

[0068] Referring to Figures 11, 12, and 13, in some embodiments of the present invention, 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 inlet 9. The powder inlet 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, in the embodiment shown in Figure 13, the bottom of the trigger block 43 has a base plate 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 cooperation of the guide holes and guide posts, the base plate and the trigger block 43 can float up and down. Limit screws are installed on the top surface of the guide posts. In this embodiment, the top of the trigger block 43 has a wedge surface, and the bottom cover 10 of the milk powder compartment is provided with a passive contact block. The bottom of the passive contact block also has a wedge surface. The two wedge surfaces can cooperate with each other. During the contact process, the bottom cover 10 of the milk powder compartment is triggered to open first, and then the bottom cover 10 of the milk powder compartment presses down on the trigger block 43 so that the bottom cover 10 of the milk powder compartment passes over the trigger block 43. In the embodiment shown in Figure 13, the elastic buffer element 44 is a spring provided 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. In the embodiment shown in Figure 12, the elastic reset element 45 is a torsion spring provided between the bottom cover 10 of the milk powder compartment and the rotating part. The bottom cover 10 of the milk powder compartment is connected to the rotating part 6 through a vertical rotating shaft, thereby realizing that the bottom cover 10 of the milk powder compartment can swing horizontally relative to the rotating part 6. The torsion spring is fitted on the vertical rotating shaft, and the two torsion arms of the torsion spring rest on the bottom cover 10 of the milk powder compartment and the rotating part 6 respectively. The force of the torsion spring makes the bottom cover 10 of the milk powder compartment automatically reset. When the rotating part 6 rotates to the set position, the trigger block 43 can trigger the milk powder compartment bottom cover 10 to open. When the rotating part 6 continues to rotate at the set angle, the milk powder compartment bottom cover 10 can make the trigger block 43 slide down against the force of the elastic buffer element 44, so that it passes over the trigger block 43. Then the elastic reset element 45 can make the milk powder compartment bottom cover 10 swing back to its original position.

[0069] Referring to Figure 3, in one embodiment of the present invention, the milk powder compartment bottom cover 10 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 milk powder compartment 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 point where the milk powder compartment 8 is close to or directly facing the mixing module 5, the body limiting protrusion 32 contacts the milk powder compartment bottom cover 10, causing the milk powder compartment bottom cover 10 to rotate and open.

[0070] Referring to Figures 5 and 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.

[0071] Referring to Figure 7, in another embodiment of the present invention, 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 slide rod 35 is provided on the rotating member 6 for each milk powder compartment 8, with one end of the slide 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 member 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 slide rod 35 corresponding to the milk powder compartment 8. The slide 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.

[0072] Referring to Figure 8, in another embodiment of the present invention, 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. The milk powder compartment opening trigger mechanism includes a power component 37 provided on the main body 1 that is capable of outputting linear motion. When the rotating component 6 rotates to the position where the milk powder compartment 8 is directly 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.

[0073] In order to clean the residual powder in the milk powder compartment 8, in the embodiment shown in Figure 4, 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 milk powder compartment 8 when the rotating part 6 rotates to a position that moves the milk powder compartment 8 away from the baby bottle, so that the residual milk powder in the compartment falls onto the powder receiving tray 38.

[0074] 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, which then stops the rotating part 6 from rotating.

[0075] In some embodiments of the present invention, the main body 1 is provided with a sensor capable of detecting the position of the baby bottle. The sensor is located on the side of the main body 1 and at the edge of the recessed area of ​​the mixing module 5 and above the mixing module 5. The height at which the sensor is installed limits the height at which the baby bottle rises. The sensor is connected to the controller of the formula maker. The controller controls the lifting device 12 of the mixing module according to the detection signal of the sensor, so that the baby bottle 40 stops rising when the opening reaches the set position. Therefore, when the lifting device 12 of the mixing module drives the mixing module 5 to rise, baby bottles of different heights can approach the powder outlet 9.

[0076] Referring to Figure 14, in some embodiments of the present invention, the automatic formula maker further includes a control system. The control system includes a controller, and the water injection device 3, the milk powder dispensing device 4, the mixing module 5, and the mixing module lifting device 12 are all electrically connected to the controller. The controller has a first control module, a second control module, and a third control module. The first control module is configured to: control the mixing module lifting device 12 to operate so that the mixing module 5 rises, and control the water injection device 3 to operate so that water is injected during the rising of the mixing module 5. The second control module is configured to: after the mixing module 5 has risen a set distance, control the milk powder dispensing device 4 to rotate the rotating part 6 so that the powder inlet 9 of one of the milk powder compartments 8 is close to or directly facing the mixing module 5, and open the bottom cover 10 of the milk powder compartment to dispensing milk powder from the milk powder compartment 8; after the milk powder in the milk powder compartment 8 has been dispensed, control the milk powder dispensing device 4 to rotate the rotating part 6 by a set angle so that the milk powder compartment 8 moves away from the center of the mixing module 5. The third control module is configured to: control the lifting device 12 of the mixing module to lower the mixing module 5; control the operation of the mixing module 5; and control the mixing module 5 to start at any stage: when the mixing module 5 rises, when the milk powder compartment bottom cover 10 opens, or when the mixing module 5 falls. After the above improvements, opening the milk powder compartment bottom cover 10 after the mixing module 5 rises allows the bottle openings placed on the mixing module 5 to be close to the powder inlet 9 of the milk powder compartment 8, minimizing powder spillage. Water is added during the rising of the mixing module 5, and the water addition and falling of the mixing module 5 occur simultaneously with its operation, maximizing time savings and enabling rapid milk preparation. By moving the milk powder compartment 8 away from the center of the mixing module 5, the milk powder compartment 8 is kept away from the bottle openings placed on the mixing module 5, reducing the chance of the milk powder absorbing heat and becoming damp, making the milk powder compartment 8 cleaner and easier to clean.

[0077] In some embodiments of the present invention, the electrical connection between the water injection device 3, the milk powder dispensing device 4, the mixing module 5, the mixing module lifting device 12, and the controller is as follows: The controller has at least four electrical signal output terminals, each of which is electrically connected to the control terminals of the water pump 19, the rotating component drive device 7 (usually an electric motor), the bottle holder drive device 29 (usually an electric motor), and the mixing module lifting motor 31. When the controller outputs an electrical signal to the water pump 19, the water pump 19 starts or stops, realizing the injection of water into the bottle or stopping the injection of water. The controller outputs an electrical signal to the rotating component drive device 7, which can drive the rotating component 6 to rotate a set distance. When the rotating component 6 rotates to bring the powder dispensing port 9 of one of the milk powder compartments 8 close to or directly facing the mixing module 5, the milk powder compartment opening trigger mechanism or the milk powder compartment opening trigger part can trigger the bottom cover 10 of the milk powder compartment corresponding to that milk powder compartment 8 to open, realizing the dispensing of milk powder. When the controller outputs an electrical signal to the bottle holder drive device 29, the bottle holder drive device 29 can drive the bottle holder 28 to rotate in both directions, thereby mixing the milk powder and water in the bottle. When the controller outputs an electrical signal to the mixing module lifting motor 31, the mixing module lifting motor 31 can drive the mixing module 5 to rise or fall, thereby adjusting the height of the bottle.

[0078] It should be noted that the control system provided in the above embodiments is only illustrated by the division of the above functional modules. In practical applications, the above functions can be assigned to different functional modules as needed, that is, the modules or steps in the embodiments of the present invention can be further decomposed or combined.

[0081] This invention also discloses a control method for an automatic formula maker, applicable to the aforementioned automatic formula maker. Referring to Figure 15, in some embodiments of this invention, the control method for the automatic formula maker includes the following steps:

[0082] Step S100: Control the lifting device 12 of the mixing module to make the mixing module 5 rise, and control the water injection device 3 to inject water during the rising process of the mixing module 5.

[0083] Step S200: After the mixing module 5 rises a set distance, control the milk powder dispensing device 4 to rotate the rotating part 6 so that the powder inlet 9 of one of the milk powder compartments 8 is close to or directly facing the mixing module 5, and open the bottom cover 10 of the milk powder compartment to dispensing the milk powder in the milk powder compartment 8; after the milk powder in the milk powder compartment 8 is dispensed, control the milk powder dispensing device 4 to rotate the rotating part 6 by a set angle so that the milk powder compartment 8 leaves the center of the mixing module 5.

[0084] Step S300: Control the mixing module lifting device 12 to lower the mixing module 5;

[0085] The mixing module 5 is controlled to work at any stage of step S100, step S200, or step S300.

[0086] After the above improvements, opening the bottom cover 10 of the milk powder compartment after the mixing module 5 rises allows the bottle openings placed on the mixing module 5 to be close to the powder inlet 9 of the milk powder compartment 8, minimizing powder spillage. Water is added during the rising of the mixing module 5, and the water-addition mixing module 5 descends simultaneously with its operation, maximizing time savings and enabling rapid milk preparation. By moving the milk powder compartment 8 away from the center of the mixing module 5, it keeps the bottle openings away from the mixing module 5, reducing the chance of the milk powder absorbing heat and becoming damp, resulting in a cleaner and easier-to-clean milk powder compartment 8.

[0087] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
