Description

Technical Field

[0001] This utility model relates to a device for assisting in preparing formula or heating breast milk, specifically a bottle warmer with a formula dissolving function, belonging to the technical field of maternal and infant products. Background Technology

[0002] In infant feeding, the need for quick and even preparation of formula and heating of breast milk are common requirements. Preparing formula typically involves two steps: first, dissolving the formula powder evenly in water; and second, heating the formula to a suitable drinking temperature. Heating of breast milk is primarily used to heat breast milk that has been expressed and stored using a breast pump.

[0003] Traditional bottle warmers are mainly limited to heating and do not have a dissolving function. Users often need to manually or with a bottle shaker to mix the milk powder before moving the bottle to the bottle warmer for heating. The whole process is long, cumbersome and time-consuming.

[0004] On the other hand, most existing milk powder dissolving devices use a built-in motor to rotate or shake the bottle mechanically to dissolve the milk powder. However, this traditional mechanical shaking method usually results in a complex structure, requiring a motor, transmission mechanism, and clamping devices to hold bottles of different sizes, leading to a large overall product size that is inconvenient to carry and store. Secondly, the motor generates significant operating noise, which may disturb infants who require a quiet environment. Furthermore, the efficiency of mechanical rotation is limited, and the dissolving effect is not ideal for some milk powders that are prone to clumping, resulting in a long dissolving time. Due to the need for clamping devices, it has poor compatibility with the shape and size of the bottles, and may not be compatible when users change to different bottles.

[0005] In addition, existing bottle warmers mainly heat the bottle with hot water or blow hot air, transferring heat through the bottle to heat the liquid inside. This method is inefficient and the temperature is difficult to measure accurately. Utility Model Content

[0006] Based on the above background, the purpose of this utility model is to provide a milk warmer with milk powder dissolving function, which solves the technical problems of separating milk powder dissolving and warming functions in the prior art, as well as the complex device structure, high noise and poor compatibility caused by using mechanical shaking to dissolve milk powder. At the same time, it solves the technical problems of low milk warming efficiency and inaccurate liquid heating temperature in the prior art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A bottle warmer with milk powder dissolving function is used to heat the liquid in the container and assist in dissolving the powder therein. The bottle warmer with milk powder dissolving function is equipped with an ultrasonic dissolving component and an immersion heating component. The ultrasonic dissolving component is used to generate high-frequency vibration and transmit it to the container to assist in dissolving the powder. The immersion heating component has a heating element component that can be immersed in the liquid in the container and / or a temperature sensor. The heating element component is used to directly heat the liquid, and the temperature sensor is used to measure the temperature of the liquid.

[0009] Preferably, the bottle warmer with milk powder dissolving function is also provided with a base for holding the container, and the ultrasonic dissolving component includes an ultrasonic transducer and a drive circuit board disposed inside the base, and the drive circuit board is electrically connected to the ultrasonic transducer.

[0010] Preferably, the base has a support platform at the top, which is a metal resonant disk, and the ultrasonic transducer abuts against the bottom surface of the metal resonant disk.

[0011] By utilizing the excellent acoustic wave conduction characteristics of the metal resonant disk, the vibration energy generated by the ultrasonic transducer can be efficiently and evenly transmitted to the bottom of the milk powder container.

[0012] Preferably, the ultrasonic transducer is fixed to the bottom surface of the metal resonant disk by bonding or pressing.

[0013] The bonding or pressing method ensures a tight, gapless contact between the ultrasonic transducer and the metal resonant disk, guaranteeing efficient transmission of vibration energy.

[0014] Preferably, the immersion heating assembly further includes a heating element connector and a heating element support, wherein the top end of the heating element support is detachably electrically coupled to the heating element connector, and the heating element component is fixed to the bottom end of the heating element support.

[0015] Preferably, the temperature sensor is fixed to the bottom end of the heating element bracket.

[0016] Preferably, the heating element support is provided with a dust cover, which is located between the electrical coupling end of the heating element support and the heating element component, and is movable relative to the heating element support along its extension direction.

[0017] The sliding dust cover design is highly adaptable, allowing for position adjustment to accommodate containers of different heights, thus providing dust protection and sealing, and enhancing the compatibility of this bottle warmer with milk powder dissolving function with containers of different sizes.

[0018] Preferably, the bottle warmer with milk powder dissolving function also includes a support arm assembly, one end of which is connected to the base, and the other end of which is located above the support platform.

[0020] The pivotal connection design allows the entire device to be easily folded, significantly reducing its storage volume and enhancing the portability of this bottle warmer with milk powder dissolving function.

[0021] Preferably, the immersion heating assembly is detachably electrically coupled to one end of the support arm assembly located above the bearing platform.

[0022] The detachable electrical coupling design modularizes the heating function, allowing users to easily assemble or disassemble the immersion heating component to use the milk powder dissolving and warming functions simultaneously or the milk powder dissolving function alone, as needed.

This overcomes the drawbacks of traditional milk preparation processes, such as cumbersome separate operation, slow warming speed, and inaccurate temperature. The invention utilizes an ultrasonic transducer and corresponding drive circuit board within the base, transmitting the vibrations generated by the transducer to the container via a support platform. The high-frequency vibration of the ultrasonic waves rapidly dissolves the milk powder. Compared to the mechanical shaking method using a motor in existing technologies, this design greatly simplifies the structure, resulting in more thorough and rapid dissolution. Furthermore, its non-contact vibration dissolution method is not limited by the shape or size of the milk powder container, offering excellent versatility. The immersion heating method employed in this invention provides faster warming speed, more accurate liquid temperature, and is more energy-efficient than existing milk warming methods.

It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0032] In this invention, unless otherwise specified, all parts and percentages are by weight, and the equipment and raw materials used are commercially available or commonly used in the field. Unless otherwise specified, the methods in the following embodiments are conventional methods in the field. Unless otherwise specified, the components or equipment in the following embodiments are general standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0033] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following detailed description, many specific details are set forth to facilitate explanation and provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.

[0034] An embodiment of this utility model discloses a bottle warmer with a milk powder dissolving function, see reference. Figure 1 and Figure 2 The bottle warmer with milk powder dissolving function includes a base 1 with internal space, an ultrasonic transducer 2 located inside the base 1, and a drive circuit board 3.

[0035] The base 1 has a support platform 101 on top for holding the container 11. Specifically, the support platform 101 is a metal resonant disk made of stainless steel or aluminum alloy, a metal with acoustic impedance close to that of water and good conductivity, to ensure efficient transmission of vibration energy. An ultrasonic transducer 2 is located inside the base 1 and abuts against the bottom surface of the support platform 101. A drive circuit board 3 is also located inside the base 1 and is electrically connected to the ultrasonic transducer 2. When the device is started, the drive circuit board 3 drives the ultrasonic transducer 2 to operate, and the generated high-frequency vibrations are transmitted through the support platform 101 to the milk powder container 11 above it, thereby assisting in the dissolution of the milk powder. This design utilizes ultrasonic technology to replace traditional mechanical shaking, resulting in a simpler structure, quieter operation, and greater compatibility with the milk powder container 11.

[0036] The ultrasonic transducer 2 is a piezoelectric ceramic sheet, which is fixed to the bottom surface of the metal resonant disk by bonding or pressing. When bonding is used, epoxy resin adhesive or acoustic coupling agent with good sound conductivity is used to ensure that a tight, gapless contact is formed between the two, thereby minimizing the loss of vibration energy at the interface.

[0037] The base 1 also houses a battery assembly 4 for powering the drive circuit board 3. Using the battery assembly 4 significantly improves the portability of this bottle warmer with milk powder dissolving function. To ensure battery life, the battery assembly 4 is a rechargeable lithium battery pack, which is charged via a charging port located on the base 1.

[0038] The bottle warmer with milk powder dissolving function also includes a support arm assembly 5 and an immersion heating element 6. The support arm assembly 5 includes a support arm housing 502, one end of which is connected to the base 1, and the other end extends above the support platform 101. The immersion heating element 6 is detachably mounted on the end of the support arm assembly 5 located above the support platform 101 and extends toward the support platform 101, with its end maintaining a certain distance from the top surface of the support platform 101 to facilitate the placement of the container 11.

[0039] The support arm assembly 5 also includes a pivot 501, through which the support arm housing 502 is pivotally connected to the base 1. This design allows the support arm assembly 5 to rotate relative to the base 1 between an unfolded working position and a folded storage position. Users can fold the support arm assembly 5 to a position flush with the base 1, thereby significantly reducing the overall storage volume of the device and making it easy to carry.

[0040] The immersion heating assembly 6 includes a heating element 601 for immersing in the liquid within the milk powder container 11 and a temperature sensor 602 for detecting the liquid temperature. Both the heating element 601 and the temperature sensor 602 are existing technologies; for example, the heating element 601 can be a PTC ceramic heater or a PI heating film device sealed inside a metal component, and the temperature sensor 602 can be an NTC thermistor. Both the heating element 601 and the temperature sensor 602 are integrated at the end of the immersion heating assembly 6, allowing direct contact with the liquid to be heated, achieving efficient direct heating and accurate real-time temperature measurement.

[0041] In this embodiment, the structure of the immersion heating assembly 6 is further modularized, including a heating element connector 603 and a heating element support 604. The heating element connector 603 is detachably electrically coupled to the free end of the support arm assembly 5 via a mating first electrical coupler 9. The top end of the heating element support 604 is detachably electrically coupled to the heating element connector 603 via a twist-lock or magnetic second electrical coupler 10. The heating element component 601 and the temperature sensor 602 are both fixed to the bottom end of the heating element support 604. This multi-segment detachable design makes the heating function completely modular, allowing users to easily assemble or disassemble it as needed, and also greatly facilitating storage and cleaning.

[0042] A dust cover 605 is also provided on the heating element support 604. This dust cover 605 is made of elastic material such as silicone and has a central perforation, allowing it to fit snugly onto the heating element support 604. The dust cover 605 is located between the electrical coupling end of the heating element support 604 and the heating element component 601, and can move freely relative to the heating element support 604 along its extension direction. When using the heating function, the user can slide the dust cover 605 downwards according to the height of the milk powder container 11 until it just covers and seals the container opening, effectively preventing dust from falling in and providing some insulation and preventing liquid splashing.

[0043] This bottle warmer with milk powder dissolving function also includes a display module 7 and a control circuit board 8. The control circuit board 8, as the core of the entire device, is electrically connected to the display module 7, the drive circuit board 3, and the immersion heating element 6. The display module 7 typically includes an operation display circuit board and corresponding displays or indicator lights to show the user the device's current operating mode, temperature, remaining battery power, and other information, and to receive user commands. Users can use the display module 7 to select and activate the ultrasonic dissolving function or set the heating temperature, enabling convenient human-machine interaction.

[0044] When a user needs to dissolve milk powder, they place the milk powder container 11 containing water and milk powder on the support platform 101 and activate the dissolving function via the display module 7 on the device. At this time, the control circuit board 8 sends a command to the drive circuit board 3, which generates a high-frequency alternating electrical signal and applies it to the ultrasonic transducer 2. Due to the piezoelectric effect, the ultrasonic transducer 2 efficiently converts electrical energy into high-frequency mechanical vibration of the same frequency. This vibration is transmitted to the support platform 101 through close contact, causing the entire support platform 101 to resonate at a high frequency. Because the bottom of the milk powder container 11 is in contact with the support platform 101, this high-frequency vibration is further transmitted to the liquid inside the container. In the liquid, the ultrasound generates a cavitation effect, forming countless tiny bubbles that instantly form, expand, and burst. This process generates powerful micro-shock waves and jets, which can quickly break up and decompose milk powder clumps. Simultaneously, the high-frequency vibration itself also acts as a powerful stirrer. This dual effect of ultrasonic cavitation and high-frequency vibration allows milk powder to be completely and evenly dissolved in a very short time, avoiding the problems of uneven dissolution from manual shaking or low efficiency of mechanical shaking, and the whole process has low noise.

[0045] When the user needs to warm milk, the immersion heating component 6 is installed, ensuring the heating element 601 and temperature sensor 602 are completely submerged in the liquid in the milk powder container 11. Simultaneously, the dust cover 605 is slid down to precisely cover the opening of the milk powder container 11. After setting the target temperature via the display module 7, the control circuit board 8 activates the heating element 601 to directly heat the liquid. Simultaneously, the temperature sensor 602 monitors the liquid temperature in real time and feeds the data back to the control circuit board 8. The control circuit board 8 then adjusts the heating power for temperature control using a built-in control algorithm.

[0046] When a user needs to dissolve milk powder and warm milk at the same time, they can operate through the display module 7. For example, they can select to start the function of dissolving first and then heating. After starting, the control circuit board will execute the above-mentioned dissolving milk powder process and warming milk process in sequence.

[0047] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
