Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of milk warmer technology, specifically a portable milk warmer with a three-dimensional heating function and stirring function. Background Technology
[0002] As a core appliance for maintaining a constant temperature for liquid beverages such as milk and breast milk, the ease of use, uniform heating, and complete functionality of a milk warmer directly affect the user experience and safety. This is especially true for infant feeding scenarios, where the performance requirements for milk warmers are even more stringent.
[0003] Currently, traditional milk warming cups typically use a bottom heating structure, where heat can only be transferred from the bottom to the liquid inside the cup. This easily leads to temperature differences between areas of "local overheating" and "local underheating." For example, "when heating 180ml of liquid in a traditional bottom-heated milk warming cup, the bottom temperature can reach over 85℃, while the surface temperature may be below 40℃, resulting in a temperature difference of over 45℃. This can easily cause the milk proteins at the bottom to denature and burn, while the upper part remains cold." This not only fails to achieve a uniform milk warming effect but may also damage the nutrients in breast milk (such as active proteins and immune factors) due to localized high temperatures, or cause discomfort to infants and young children due to uneven temperature distribution. Furthermore, during the milk warming process, the liquid is prone to solute precipitation due to static heating (such as milk residue formed after formula preparation, or the fat layer that separates from refrigerated breast milk). If only natural heat convection is used, the precipitated substances cannot be fully mixed with the liquid, affecting the taste of the beverage and potentially leading to uneven intake by infants and young children, increasing their digestive burden. To solve this problem, some users manually shake and stir the cup, which is not only cumbersome but also poses a safety hazard of burns from contact with the hot cup, especially in situations with poor visibility, such as nighttime feeding, where the safety risk is further increased. Utility Model Content
[0004] This utility model provides a solution that addresses the problem of overly simplistic existing solutions. It offers a significantly different approach by providing a portable, three-dimensional heating milk warmer with a stirring function. This solves the problems mentioned in the background section, where traditional milk warmers typically heat from the bottom, leading to unidirectional heat transfer that can cause localized overheating or insufficient heating. This results in uneven milk warming, potentially damaging breast milk nutrition and causing discomfort to infants. Furthermore, the liquid tends to settle during warming, making natural heat convection difficult to mix, affecting taste and increasing digestive burden on infants. Manual shaking and stirring are also cumbersome.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A portable, three-dimensional heating milk warmer with a stirring function includes an outer shell. A bottom shell is fitted to the bottom of the outer shell, and a lid assembly is provided at the top. A metal cup is embedded inside the outer shell. A rotating disk is attached to the bottom of the inner wall of the metal cup, and a first heating element is provided at its bottom. A second heating element is mounted around the outer wall. A drive mechanism for driving the rotating disk to rotate is provided below the metal cup. A mounting hole is provided through the bottom of the bottom shell, and a heat sink is installed in the mounting hole. The heat sink is positioned higher than the bottom end face of the bottom shell. An energy supply component for supplying power to the device is provided on the heat sink.
[0006] More preferably, a partition is provided on the inner wall of the outer shell and below the metal cup, and heat insulation material is attached to the side of the partition facing the metal cup. The closed cavity formed by the inner wall of the outer shell, the outer wall of the metal cup and the partition is a vacuum structure.
[0007] More preferably, the drive mechanism consists of a motor and a power disk, wherein the motor is mounted on the partition, the power disk is connected to the output end of the motor, the rotating disk is provided with a magnet inside, and the power disk is provided with a magnet that corresponds to and cooperates with the magnet inside the rotating disk.
[0008] More preferably, the heat sink is provided with an energy supply component for powering the device.
[0009] More preferably, the heat sink is provided with heat-conducting rods that are uniformly distributed in a ring, and the energy supply component is located in the area enclosed by the ring-shaped heat-conducting rods.
[0010] More preferably, the bottom end face of the bottom shell is provided with ventilation grooves distributed in an annular pattern, and the bottom end face of the bottom shell is provided with a plurality of annular grooves that are staggered with the ventilation grooves.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This portable milk warmer cup utilizes a rotating disc, a first heating element, a second heating element, a motor, and a power plate. The three-dimensional heating structure of the first and second heating elements can quickly raise the temperature of milk and other materials inside the cup, while avoiding the problem of localized high-heat scorching caused by traditional single bottom heating. This optimizes the heating effect and material quality. Furthermore, the motor drives the power plate, and the magnetic coupling between the power plate and the rotating disc achieves contactless transmission, preventing uneven material density caused by localized accumulation of milk curds. It also promotes material flow to evenly absorb heat, further improving heating efficiency and uniformity.
[0012] A double heat insulation structure is constructed by using a partition, outer shell, hardware cup, and vacuum cavity enclosed by the partition to block heat conduction towards the bottom shell, preventing damage to core components such as motors and energy supply components inside the bottom shell due to high temperatures, thus ensuring component stability. In addition, the heat conduction rod of the heat sink and the ventilation groove at the bottom of the bottom shell form a synergistic heat dissipation structure. The heat conduction rod can conduct the heat generated by the energy supply components to the heat sink, and the air circulation channel constructed by the ventilation groove accelerates heat dissipation, prevents heat accumulation, and ensures the overall stable operation of the equipment.
[0013] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0018] Please refer to the appendix carefully. Figure 1-2A portable, three-dimensional heating milk warmer with stirring function includes an outer shell 1, a bottom shell 2 mounted on the bottom of the outer shell 1, and a cup lid assembly 3 mounted on the top. A metal cup 4 is embedded inside the outer shell 1. A temperature sensor is installed on the inner wall or bottom of the metal cup 4 for real-time monitoring of the material temperature. A rotating disk 5 is attached to the bottom of the inner wall of the metal cup 4, and a first heating element 6 is installed at its bottom. A second heating element 7 is mounted around the outer wall. A drive mechanism for driving the rotating disk 5 to rotate is provided below the metal cup 4. A mounting hole is opened through the bottom of the bottom shell 2, and a heat sink 11 is installed in the mounting hole. The mounting position of the heat sink 11 is higher than the bottom end face of the bottom shell 2. An energy supply component 13 for powering the device is provided on the heat sink 11. The energy supply component 13 is a rechargeable lithium battery pack that supports USB-C interface charging.
[0019] The housing 1 contains a microprocessor control unit (MCU), which is electrically connected to a temperature sensor, a first heating element 6, a second heating element 7, and a motor 9. The MCU is configured to: receive the temperature sensor signal, control the power output of the first heating element 6 and the second heating element 7 through a PID algorithm to stabilize the material temperature at the user-set value (such as 40℃, 45℃, etc.); and control the motor 9 to operate intermittently or continuously.
[0020] In this embodiment, as Figure 1 and Figure 2 As shown, a partition 8 is provided on the inner wall of the outer shell 1 and below the hardware cup 4. A heat insulation material is attached to the side of the partition 8 facing the hardware cup 4. The heat insulation material can be aerogel felt, glass fiber cotton, ceramic fiber board or high temperature resistant silicone pad. The closed cavity formed by the inner wall of the outer shell 1, the outer wall of the hardware cup 4 and the partition 8 is set as a vacuum structure.
[0021] By using the heat insulation material on the partition 8, combined with the vacuum cavity enclosed by the outer shell 1, the metal cup 4 and the partition 8, a double heat insulation structure is constructed. This can prevent the heat from the metal cup 4 and the first heating element 6 from being conducted to the bottom shell 2, reduce heat loss and improve energy efficiency, and also isolate the high temperature from being transmitted downwards, preventing the drive mechanism and energy supply component 13 inside the bottom shell 2 from being damaged due to overheating.
[0022] In this embodiment, as Figure 2As shown, the drive mechanism consists of a motor 9 and a power disk 10. The motor 9 is mounted on the partition 8, and the power disk 10 is connected to the output end of the motor 9. The rotating disk 5 has a magnet inside, and the power disk 10 has a magnet that corresponds to and cooperates with the magnet inside the rotating disk 5 (the magnets inside the rotating disk 5 and the power disk 10 are neodymium iron boron N-series permanent magnets). The power disk 10 is connected to the output end of the motor 9, and the rotating disk 5 and the power disk 10 adopt a drive method with corresponding magnets. Power transmission can be achieved without opening a through hole in the hardware cup 4, ensuring the sealing of the hardware cup 4 and preventing internal liquid leakage. When the rotating disk 5 rotates, it can stir the liquid inside the hardware cup 4. The rotating disk 5 can be easily removed from the bottom of the hardware cup 4 by magnetic attraction, making it convenient for users to clean.
[0023] In this embodiment, as Figure 2 As shown, the first heating element 6 is preferably a heating plate, but not limited to it; the second heating element 7 is preferably a PI heating film, but not limited to it; the first heating element 6 can directly heat the material inside the metal cup 4 from the bottom, and the second heating element 7 can utilize the flexible bonding characteristics of the PI heating film to tightly wrap the side wall of the metal cup 4 to achieve uniform heating. The two together can form a three-dimensional heating structure, avoiding the problem of local overheating or uneven heating of the material inside the metal cup 4, and improving the heating effect.
[0024] In this embodiment, as Figure 2 As shown, the heat sink 11 is provided with heat-conducting rods 12 evenly distributed in a ring, and the energy supply component 13 is located in the area enclosed by the ring-distributed heat-conducting rods 12. The heat sink 11 is made of aluminum alloy. The ring-shaped heat-conducting rods 12 can expand the heat-conducting contact area and conduct the heat generated by the energy supply component 13 during operation to the heat sink 11. In conjunction with the heat dissipation function of the heat sink 11, local heat accumulation can be avoided, which would affect the operational stability of the energy supply component 13.
[0025] In this embodiment, as Figure 1 and Figure 2 As shown, the bottom end face of the bottom shell 2 is provided with a ring-shaped ventilation slot, and multiple ring-shaped slots that are staggered with the ventilation slots are provided on the bottom end face of the bottom shell 2; the ring-shaped ventilation slots on the bottom end face of the bottom shell 2 work together with the heat sink 11 and the heat conduction rod 12 to dissipate heat. The ring-shaped ventilation slots form an air circulation channel, which helps the heat conduction rod 12 to conduct heat to the heat sink 11 to be quickly discharged, thereby improving the heat dissipation efficiency.
[0026] The specific operating procedure of this utility is as follows: First, the energy supply component 13 installed on the heat sink 11 supplies power to the entire device. After power is supplied, the first heating element 6 and the second heating element 7 start up synchronously. The first heating element 6 directly heats the bottom of the milk and other materials in the cup, while the second heating element 7 provides uniform heating to the side wall. The two perform three-dimensional heating, which can quickly increase the temperature of the materials and avoid the problem of milk burning caused by local high heat at the bottom. At the same time, the motor 9 installed on the partition 8 starts, driving the power disk 10 connected to its output end to rotate. Since the power disk 10 and the rotating disk 5 at the bottom of the inner wall of the metal cup 4 are equipped with corresponding magnets, the rotational force of the power disk 10 can be transmitted to the rotating disk 5 without contact through magnetic coupling, so that the rotating disk 5 rotates in the metal cup 4. The stirring action of the rotating disk 5 can prevent the uneven material density caused by the local accumulation of milk curds, and at the same time allow the material in the cup to flow, evenly absorb the heat transferred by the first heating element 6 and the second heating element 7, and improve the heating efficiency and heating uniformity. During this process, the heat insulation material on the side of the partition 8 facing the metal cup 4, together with the vacuum cavity enclosed by the outer shell 1, the metal cup 4 and the partition 8, forms a double heat insulation structure, blocking the heat conduction from the metal cup 4 and the heating element to the bottom shell 2, and preventing the motor 9, energy supply component 13 and other components inside the bottom shell 2 from being damaged by high temperature. At the same time, the heat conduction rods 12 evenly distributed in a ring on the heat dissipation plate 11 conduct the heat generated by the operation of the energy supply component 13 to the heat dissipation plate 11. Combined with the ventilation grooves distributed in a ring at the bottom of the bottom shell 2, an air circulation channel is constructed, so that the heat on the heat dissipation plate 11 is discharged, ensuring the overall stable operation of the equipment.
[0027] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
