Description

Technical Field

[0001] This invention relates to the field of maternal and infant electrical appliances technology, and in particular to an automatic formula maker with an integrated sterilization cabinet. Background Technology

[0002] With the advancement of baby appliance technology, automatic formula makers, with their core advantages of precise temperature control and quantitative formula dispensing, have gradually become one of the essential appliances for families with infants. Currently, most mainstream automatic formula makers on the market focus on optimizing formula dispensing accuracy and water dispensing efficiency. The applicant's earlier patent application, number 202511203268.X, entitled "A Formula Maker with High-Precision Dynamic Weighing Function," has solved the pain point of accurate formula powder ratio and water temperature control during the formula dispensing process. However, existing formula makers do not integrate bottle sterilization and drying functions.

[0003] In daily childcare scenarios, accessories such as bottles and nipples need frequent sterilization. Users need to purchase dedicated sterilization equipment, which not only occupies limited counter space in the mother and baby area but also requires repeated operation between formula preparation and sterilization equipment, significantly increasing the burden of childcare. Some integrated devices have defects such as sterilization blind spots, low drying efficiency, conflicts with the water and electrical circuit layout of the formula preparation module, and safety hazards, failing to meet the needs of mothers and infants for integrated, one-stop formula preparation equipment. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the main purpose of this invention is to provide an automatic milk maker with an integrated sterilization cabinet, so as to solve the problems that existing milk makers do not have sterilization and drying functions, users need to purchase additional equipment, occupy space and are cumbersome to operate, and realize one-stop sterilization, drying and milk preparation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic milk maker with an integrated sterilization cabinet, comprising a main housing and a base plate located below the main housing. The main housing is provided with a hot water supply module and an automatic milk maker module. The main housing is also provided with a sterilization and drying module. The sterilization and drying module includes a cabinet disposed in the main housing. The base plate and the bottom of the cabinet have communicating ventilation holes. The cabinet is provided with a bracket for supporting milk bottles and their accessories. The top of the cabinet is provided with an ultraviolet sterilization lamp. The bottom of the cabinet is provided with a drying air duct assembly. The front of the cabinet is provided with a door that can close the cabinet.

[0006] Preferably, the drying air duct assembly includes a fan, an electric heating unit, and a split-type air duct connected in sequence, wherein the split-type air duct includes two hot air outlets facing the support.

[0007] Preferably, each of the two hot air outlets is provided with a cover, and the side wall of the cover is provided with an air outlet hole.

[0008] Preferably, the inner wall of the box is provided with multiple diamond-shaped reflective surfaces.

[0009] Preferably, the base plate is provided with a barrier at the ventilation holes.

[0010] This invention offers the following advantages over existing technologies: It integrates the cabinet and automatic formula preparation module into a single housing, eliminating the need for separate sterilization equipment and significantly saving space on the mother-and-baby counter. The combination of a UV sterilization lamp and a diamond-shaped reflective surface ensures thorough sterilization without any blind spots within the cavity. The bottom drying air duct assembly, along with a two-way air duct and a cover vent, allows hot air to evenly pass through the bottles and accessories from bottom to top, resulting in high drying efficiency and no residual water. Users can directly remove the bottles from the cabinet to prepare formula, eliminating the need for repeated operations between multiple devices and truly achieving a one-stop process of "sterilization—drying—formula preparation."

[0018] The invention will now be further described with reference to the accompanying drawings.

[0019] like Figure 1As shown, this invention provides an automatic formula maker with an integrated sterilization cabinet. The automatic formula maker includes a main housing 1 and a base plate 2 located at the bottom of the main housing 1. The interior of the main housing 1 is functionally divided into three main areas: an automatic formula maker module 4, a hot water supply module 3, and a sterilization and drying module 5. The hot water supply module 3 and the automatic formula maker module 4 can adopt the structure disclosed in the applicant's prior patent application with application number 202511203268.X, which will not be elaborated further here.

[0020] The core improvement of this invention lies in the integrated design of the disinfection and drying module 5. Specifically, the disinfection and drying module 5 includes a box 6 fixedly installed in the main housing 1, which has an independent processing space. To achieve air circulation, ventilation holes 7 are provided on the bottom plate 2 and the bottom of the box 6, which can realize air circulation between the inside and outside of the box 6.

[0021] Inside the housing 6, there is a detachable support 8 for supporting accessories such as baby bottles, nipples, and bottle caps. The support 8 can be made of stainless steel wire or food-grade high-temperature resistant plastic, and its structure includes a lower support 8 for inverting the baby bottles and an upper support 8 for supporting the accessories.

[0022] To ensure effective disinfection, at least one ultraviolet (UV) disinfection lamp 9 is installed at the top center of the cabinet 6. This UV disinfection lamp 9 emits short-wave ultraviolet light to efficiently sterilize items placed on the support 8. Simultaneously, to improve the reflection efficiency of ultraviolet light and eliminate disinfection blind spots, the inner sidewall of the cabinet 6 is preferably provided with multiple diamond-shaped reflective surfaces 17. These diamond-shaped reflective surfaces 17 diffusely reflect ultraviolet light, ensuring that bottles and accessories in every corner of the cabinet 6 receive sufficient ultraviolet irradiation.

[0023] Regarding the drying function, a drying air duct assembly is provided at the bottom of the housing 6. Specifically, this drying air duct assembly includes a fan 11, an electric heating unit 12, and a split-type air duct 13 connected in sequence. The fan 11 draws in air from the outside, which is heated into dry hot air by the electric heating unit 12 before entering the split-type air duct 13. The split-type air duct 13 has two hot air outlets 14 facing the support 8, thereby evenly guiding the hot air to the bottles and accessories on the support 8. The fan 11 is a small, quiet axial or centrifugal fan. The electric heating unit 12 is a PTC ceramic heating element or a nickel-chromium alloy heating wire, which generates dry hot air.

[0024] Furthermore, a cover 15 is provided on each of the hot air outlets 14, and multiple air outlet holes 16 are opened on the side wall of the cover 15. This side air outlet structure can avoid the hot air blowing directly vertically upward and violently, preventing the baby bottle or small parts from being blown over or moved. At the same time, it can also make the hot air more evenly and gently distributed throughout the entire chamber 6, improving drying efficiency and stability.

[0025] Two of the hot air outlets 14 and the cover 15 are preferably located at the mouth of an inverted baby bottle.

[0026] Furthermore, to prevent the hot and humid air exhausted from the ventilation holes 7 at the bottom of the housing 6 from flowing back into the machine or causing water accumulation under the base plate 2, a ring of upward-extending baffle 18 is provided on the base plate 2 at the corresponding position of the ventilation holes 7. This baffle 18 can effectively guide and isolate the exhausted air, protecting the safety of other electronic components inside the machine.

[0027] On the front of the chamber 6, there is a slewing door 10 that can close the chamber 6. Preferably, the door has a transparent window embedded in it, allowing the user to observe the disinfection and drying process without opening the door. A sealing ring is provided around the slewing door 10 to ensure that heat and ultraviolet light do not leak out during operation.

[0028] The working process is as follows: When the automatic milk maker of the integrated sterilizer of this invention activates the sterilization and drying function, the user first opens the switch door 10, places the cleaned bottles, nipples, and other accessories on the support 8, and then closes the switch door 10. After starting the sterilization and drying program, the ultraviolet sterilization lamp 9 first lights up to continuously sterilize the accessories with ultraviolet light. Then the drying air duct assembly starts working: the fan 11 starts, the electric heating unit 12 heats up rapidly, and the generated hot air is blown out laterally through the cover 15 on the one-to-two air duct 13 and the two hot air outlets 14, flowing evenly over the surface of the bottles and accessories, taking away moisture. The humid and hot air carrying water vapor is discharged to the outside of the machine through the ventilation holes 7 at the bottom of the cabinet 6 and the baffle 18 on the bottom plate 2 under the pressure of the fan 11. After the drying program is completed, the user can take out the dry and sterile bottles and use the hot water supply module 3 and the automatic milk maker module 4 to make milk immediately.

[0029] Testing revealed that this invention integrates the independent sterilization and drying module 5 with the main body of the milk maker, achieving thorough sterilization through the combination of a top-mounted UV lamp within the housing 6 and a diamond-shaped reflective surface 17 on the side walls. The bottom drying air duct assembly, along with the dual-flow air duct 13 and a cover 15 with side holes, ensures efficient, gentle, and uniform drying, preventing component displacement. Furthermore, the bottom-connected ventilation holes 7 and the enclosure 18 effectively address the safety hazards posed by hot and humid air emissions to the internal circuitry.

[0030] Therefore, this implementation method effectively solves the problems of existing milk maker lacking sterilization and drying functions, requiring users to purchase additional equipment which takes up space and is cumbersome to operate. It truly achieves the goal of one-stop sterilization, drying and milk preparation integration, significantly improving the user's convenience.
