Description

Technical Field

[0001] This application relates to the technical field of maternal and infant products, and in particular to a formula frying mechanism and a formula frying machine. Background Technology

[0002] Prepared formula, as one of the food sources for infants, effectively addresses issues such as insufficient breast milk supply or the inability to breastfeed at certain times. The typical method for preparing formula involves first pouring hot water (usually 45°C) into the bottle, then adding the measured amount of formula powder, followed by rotating or shaking the bottle to ensure thorough mixing. This series of actions can be somewhat tiring for the user. To address this, some automated formula preparation devices have emerged on the market.

[0003] When the relevant formula preparation equipment is working, after hot water and milk powder are added to the bottle, a stirring mechanism needs to be inserted into the bottle to stir so that the milk powder and water are mixed. However, the stirring mechanism comes into direct contact with the milk, which can cause hygiene problems. In addition, the stirring mechanism needs to be disassembled and cleaned after use, which will increase the user's workload and affect the user experience. Utility Model Content

[0004] Therefore, it is necessary to provide a milk frying mechanism and milk frying machine to address the problems of unsanitary conditions and poor user experience associated with traditional technologies.

[0005] A first aspect of this application provides a milk-making execution mechanism, comprising:

[0008] A drive module is disposed in the cabin and is connected to the bottle holder for driving the bottle holder to rotate and shake the bottles back and forth.

[0009] The formula-making mechanism in this solution is used in a formula maker to rotate and shake the baby bottle, automatically mixing the hot water and formula powder inside. Specifically, during use, the baby bottle is placed in the bottle holder within the receiving compartment, and then measured amounts of hot water and formula powder are added to each bottle. The drive module is then activated, which drives the bottle holder, causing the bottle to rotate and shake reciprocally. This ensures the hot water and formula powder are mixed evenly by swirling the bottle's flow path. Compared to traditional technologies that require a stirring mechanism, this solution avoids external objects coming into contact with the milk in the bottle, fundamentally eliminating hygiene issues. It also eliminates the need to disassemble and clean the stirring mechanism, reducing the user's burden and improving the overall user experience.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0034] See Figure 1 and Figure 3 This application illustrates a formula preparation mechanism 10, which includes a housing 11, a bottle holder 12, and a drive module 13. The housing 11 is the main component of the formula preparation mechanism 10, serving to house and integrate the bottle holder 12 and the drive module 13.

[0035] For example, in this embodiment, the cabin 11 is a semi-enclosed box-shaped component formed by bending and assembling metal sheets. It has a simple structure, light weight, and low manufacturing cost.

[0036] The cabin 11 has a through-type storage compartment 111. The through-type storage compartment 111 is designed and manufactured on the cabin 11 to facilitate the installation of the bottle holder 12 into the storage compartment 111 from bottom to bottom, and also to facilitate the direct connection of the bottle holder 12 installed in the storage compartment 111 to the drive module 13.

[0037] In this application, the containment chamber 111 has a circular slot structure, and the bottle holder 12 also adopts a cylindrical structure design.

[0038] Please continue reading. Figure 3 In addition, the top surface of the cabin 11 is provided with a recess 112. When the bottle is placed in the bottle holder 12, the bottle cap can be removed and placed in the recess 112 for temporary storage. At the same time, the opened bottle makes it easy to fill it with hot water and formula through the bottle opening.

[0039] The bottle rack 12 is rotatably mounted in the storage compartment 111 and is used to hold baby bottles. The drive module 13 is mounted in the cabin 11 and is connected to the bottle rack 12 for driving the bottle rack 12 to rotate and shake the baby bottles.

[0040] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: The milk-making actuator 10 of this solution is applied in a milk maker to rotate and shake the baby bottle, so that the hot water and milk powder in the bottle are automatically mixed evenly. Specifically, during use, the baby bottle is placed in the bottle rack 12 in the receiving chamber 111, and then a certain amount of hot water and milk powder are fed into the bottle respectively; then the drive module 13 is activated, which drives the bottle rack 12, thereby causing the baby bottle to rotate and shake back and forth, so that the hot water and milk powder in the bottle can shake and flow synchronously with the bottle, thereby achieving the purpose of even mixing. Compared with the traditional technology that requires the use of a stirring mechanism, this solution avoids external objects from contacting the milk in the bottle, fundamentally eliminating the occurrence of hygiene problems, and also saves the workload of disassembling and cleaning the stirring mechanism, reducing the burden on the user, and thus helping to improve the user experience.

[0041] Please continue reading. Figures 1 to 3 In one embodiment, the bottle holder 12 includes a bracket 121 and a bottle clip 122. The bracket 121 is rotatably disposed in the receiving compartment 111, and the bottle clip 122 is installed in the bracket 121. The bottle clip 122 is provided with a clamping groove 1221, and the bracket 121 is provided with a receiving groove 1211. The receiving groove 1211 communicates with the clamping groove 1221.

[0042] The bracket 121 is used to hold the bottle clamp 122. The bracket 121 is designed with a flanged structure. When the bracket 121 is placed into the receiving compartment 111, the flanged structure fastens to the top surface of the compartment 11 to achieve the installation and positioning of the bracket 121, and to provide guidance and limit for the rotation and shaking movement of the bottle holder 12. The bottle is inserted into the clamping groove 1221 of the bottle clamp 122 and can be clamped and fixed to ensure that the bottle is installed securely. At this time, the bottle passes through the clamping groove 1221 and the receiving groove 1211, with sufficient installation depth, so that the bottle is not easy to loosen and fall off during rotation and shaking.

[0043] Specifically, in one optional embodiment, the bottle clamp 122 includes a ring frame 1222 and multiple elastic clamping arms 1223. The multiple elastic clamping arms 1223 are spaced apart along the circumferential direction on the inner side of the ring frame 1222 and cooperate to form a clamping groove 1221. The ring frame 1222 is used to load and integrate the multiple elastic clamping arms 1223, so that the multiple elastic clamping arms 1223 are arranged in a ring at intervals along the circumferential direction, thereby cooperating to form a clamping groove 1221. When the bottle is inserted into the clamping groove 1221 from above and below, the elastic clamping arms 1223 are squeezed and deformed and retracted. The multiple elastic clamping arms 1223 simultaneously apply an elastic clamping force to the bottle, thereby clamping the bottle 122 tightly. This elastic clamping method for the bottle has good stability, good reliability for repeated assembly and disassembly, and can avoid damage to the bottle.

[0044] Optionally, the elastic clamping arm 1223 and the ring frame 1222 are integrally formed and can be made of materials such as metal or plastic.

[0045] Optionally, the elastic clamping arm 1223 can be a straight structure with an incline, or an arc-shaped structure with a bend, etc., whichever is more appropriate to the specific needs.

[0046] Please continue reading. Figure 3 Furthermore, based on any of the above embodiments, the drive module 13 includes a drive motor 131, a drive wheel 132, a transmission wheel 133, a drive bracket 134, and a bearing 135. The bracket 121 is rotatably connected to the drive bracket 134 through the bearing 135. The drive motor 131 is mounted on the drive bracket 134 and connected to the drive wheel 132. The drive wheel 132 is connected to the transmission wheel 133, and the transmission wheel 133 is connected to the bracket 121 to drive the bracket 121 to reciprocate and rotate.

[0047] During operation, the drive motor 131 first drives the drive wheel 132 to rotate, and then the drive wheel 132 drives the transmission wheel 133 to rotate. Since the transmission wheel 133 is connected to the bracket 121, the bracket 121 can rotate synchronously under the drive of the transmission wheel 133. By controlling the drive motor 131 to alternately output rotational driving force in both directions, the bottles in the bottle holder 12 can be driven to rotate and shake back and forth, thus automatically mixing the milk.

[0048] The bracket 121 is rotatably mounted to the drive bracket 134 via a bearing 135. The bearing 135 not only provides rotational support for the bracket 121, but also prevents the bracket 121 from directly rotating and contacting the drive bracket 134, thus avoiding friction and wear. The bearing 135 can be any mature and similar bearing product from the existing technology, and no specific limitation is made here.

[0049] The drive wheel 132 and the transmission wheel 133 can adopt any specific structural form such as a gear set, a pulley set, or a sprocket set, and can be flexibly selected according to actual needs.

[0050] Please continue reading. Figure 1 In one embodiment, the milk-making actuator 10 further includes a seat 14 and a door 15. The seat 14 is provided with a compartment 141, and the bottom wall of the compartment 141 is provided with a slide rail 142. The cabin 11 is slidably disposed on the slide rail 142. The cabin 11 is rotatably connected to the door 15 through a linkage rod 16. The door 15 is rotatably connected to the seat 14. The door 15 can drive the cabin 11 to enter and exit the compartment 141 through the linkage rod 16.

[0051] The base 14 is the main component of the formula maker, used to mount and fix the formula preparation mechanism 10. During use, by pulling the door 15 outwards and rotating it open, the linkage rod 16 simultaneously pulls the housing 11, allowing the housing 11 to slide along the slide rail 142 from the compartment 141 to the outside of the base 14, thus exposing the bottle rack 12 to the user. This allows for easy insertion and removal of bottles from the bottle rack 12. After completing the operation, simply push the door 15 upwards to close it. The door 15 then pushes the linkage rod 16, which in turn pushes the housing 11 back into the compartment 141 along the slide rail 142. This structural design makes the operation of the housing 11 entering and exiting the compartment 141 and retrieving bottles more convenient, effortless, and efficient, greatly enhancing the user experience.

[0052] Please continue reading. Figure 1 Specifically, there are two linkage rods 16. One end of one linkage rod 16 is rotatably connected to the left side wall of the cabin 11 via a pin, and the other end is rotatably connected to the hatch 15 via a pin. The other linkage rod 16 is rotatably connected to the right side wall of the cabin 11 via a pin, and the other end is rotatably connected to the hatch 15 via a pin. At this time, both sides of the hatch 15 are symmetrically connected to both sides of the cabin 11, which can ensure that the thrust or pull force on the cabin 11 is balanced, and avoid the cabin 11 being tilted due to force, which would cause movement obstruction and affect the normal operation of the cabin 11 entering and exiting the compartment 141.

[0053] Two slide rails 142 are also provided, arranged side by side at intervals, and slide in contact with the left and right sides of the bottom wall of the cabin 11 respectively, providing the cabin 11 with more stable sliding support and guidance.

[0054] Please continue reading. Figure 1 and Figure 2Furthermore, based on any of the above embodiments, the formula preparation mechanism 10 also includes a weighing module 17, which is located at the bottom of the compartment 141 and abuts against the cabin 11. By installing the weighing module 17 at the bottom of the cabin 11, when hot water and formula are added to the bottle in sequence, the weighing function of the weighing module 17 can accurately control the amount of hot water and formula added to the bottle, achieving precise quantitative addition.

[0055] For example, in an optional embodiment, the weighing module 17 includes a weighing sensor 171, a contact 172, a first elastic support 173 and a second elastic support 174, the first elastic support 173 and the second elastic support 174 being connected side by side at intervals below the weighing sensor 171, the contact 172 being connected above the weighing sensor 171, and the contact 172 being slidably abutting against the cabin 11.

[0056] The contact 172 is installed above the load cell 171 so that the contact 172 directly abuts against the cabin 11. This avoids the cabin 11 directly squeezing the load cell 171, which could easily damage the load cell 171. It also avoids friction and wear on the load cell 171 when the cabin 11 slides in and out of the cabin 141.

[0057] In other words, the contact 172 establishes a weighing link between the cabin 11 and the load cell 171, while also providing safety protection for the load cell 171. For example, the contact 172 may be made of a wear-resistant material, and the surface of the contact 172 that contacts the cabin 11 may be a convex arc.

[0058] Furthermore, a first elastic support 173 and a second elastic support 174 are installed side by side below the load cell 171. On the one hand, this provides a more balanced support force for the load cell 171, ensuring a stable posture and thus helping to obtain more accurate weighing results. On the other hand, when the cabin 11 is inside the compartment 141 and pressure is applied to the load cell 171 through the contact member 172, the first elastic support 173 and the second elastic support 174 can also provide the load cell 171 with more sufficient elastic support force to support the contact member 172 to effectively abut against the cabin 11, avoiding gaps due to insufficient support force, which would affect the measurement accuracy of the load cell 171.

[0059] Optionally, the first elastic support 173 and the second elastic support 174 can be any one of the following, but not limited to, springs, elastic columns, and spring sheets, and can be flexibly selected according to actual needs.

[0060] Generally, milk provided to infants and young children needs to be kept at a suitable temperature (e.g., 45°C). This avoids the risk of gastrointestinal discomfort and diarrhea caused by drinking milk that is too cold. It also ensures that infants and young children can effectively absorb the nutrients in the milk, promoting their growth. Therefore, even if hot water is added to the bottle at the required temperature, factors such as mixing the hot water with the formula, shaking, and the user not promptly taking the mixed milk can cause the milk temperature to drop and not reach the optimal level.

[0061] Please continue reading. Figure 1 and Figure 2 To address the aforementioned issues, in one embodiment, the milk-making actuator 10 further includes a hot air module 18. The base 14 is provided with a connected mounting cavity 143 and an air outlet 144. The mounting cavity 143 is connected to the chamber 141 through the air outlet 144. The hot air module 18 is disposed in the mounting cavity 143 and can deliver hot air to the chamber 141 through the air outlet 144.

[0062] A hot air duct is formed inside the cabin 11, which is arranged around the bottle rack 12 and is connected to the cabin 141.

[0063] Therefore, during the entire process of preparing milk, the hot air module 18 continuously delivers hot air into the compartment 141 through the air outlet 144. The hot air in the compartment 141 further flows into the hot air duct inside the cabin 11, which keeps the bottles in the bottle rack 12 in a suitable temperature environment and achieves the effect of keeping the milk warm.

[0064] Specifically, in the above embodiment, the hot air module 18 includes a fan 181, a fan heater 182, and a temperature controller. The fan heater 182 is disposed between the air outlet 144 and the air outlet of the fan 181. The temperature controller is disposed in the chamber 141 and electrically connected to the fan 181 and / or the fan heater 182. When the fan 181 operates, it blows airflow towards the fan heater 182. The airflow is heated into hot air as it flows through the fan heater 182. The hot air is then delivered into the chamber 141 and the hot air duct to achieve the effect of keeping the baby bottle warm or heating it. The structure is simple and the heating effect is good.

[0065] The thermostat can flexibly adjust the power of the fan 181 and / or the heating power of the air heater 182 by detecting the temperature value inside the cabin 141 in real time, thereby obtaining hot air at the required temperature.

[0066] In addition to the above, this application also proposes a milk maker, which includes the milk maker actuator 10 as described in any of the above embodiments.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
