[0027] like Figures 1 to 4 As shown, this is a bottle warmer according to one embodiment of the present invention.

[0028] Please see Figures 1-3 The bottle warmer of this utility model embodiment includes a main unit shell 10, a base 20, an inner liner 30, a heating element 40, a circuit board assembly 50, and a control knob 60. The base 20 is located at the bottom of the main unit shell 10 and has an inwardly recessed portion 21. The inwardly recessed portion 21 has a plurality of heat dissipation holes 211. The inner liner 30 is detachably connected to the main unit shell 10 and is located in the inner cavity of the main unit shell 10. The bottom of the inner liner 30 has an inwardly recessed support portion 31 and a first through hole 311. The heating element 40 is connected to the inner liner 30 and is located below the support portion 31. The control knob 60 is installed on the side wall of the main unit shell 10. The circuit board assembly 50 is installed on the base 20. The control knob 60 and the heating element 40 are electrically connected to the circuit board assembly 50, respectively.

[0029] The working principle of the bottle warmer according to this embodiment of the utility model is as follows:

[0030] First, pour an appropriate amount of water into the inner tank 30. Then, adjust the setting to the desired level using the control knob 60, and place the bottle inside. The heating plate 41 then heats the bottle, using water as a heat transfer medium to transfer heat to the bottle, thus achieving the heating effect. After the bottle warmer is turned on, it will first use maximum power to quickly raise the water temperature to the desired level, and then control the water temperature at a higher level through intermittent heating, ensuring the bottle reaches the desired temperature within two and a half minutes.

[0031] The bottle warmer of this utility model has an upwardly recessed inner portion 21 formed by the base 20. The inner portion 21 is provided with a plurality of heat dissipation holes 211. These heat dissipation holes 211 can quickly dissipate the heat generated when the bottle warmer is working, effectively avoiding the problem of overheating caused by heat accumulation, and ensuring that the bottle warmer can operate stably for a long time. Moreover, the circuit board assembly 50 is installed on the base 20 and maintains a relatively independent space from the heating element 40. The good heat dissipation effect can effectively reduce the temperature around the circuit board, avoid damage to the electronic components on the circuit board by high temperature, and extend the service life of the electronic components, thereby ensuring the stability and reliability of the bottle warmer control circuit, making it safer and more reassuring for users to use.

[0032] Please see Figure 2 and Figure 3 As shown, in some embodiments, for example, a shielding part 22 is provided on the base 20, and the shielding part 22 is located directly below the heat dissipation hole 211. The shielding part 22 on the base 20 directly below the heat dissipation hole 211 is designed to allow hot air to be discharged smoothly through the heat dissipation hole 211. At the same time, the shielding part 22 changes the movement trajectory of impurities, reducing the amount of impurities entering the bottle warmer. This not only ensures the efficient heat dissipation of the bottle warmer, but also reduces the damage to internal parts caused by the accumulation of impurities, thus extending the service life of the equipment.

[0033] In this embodiment, the shielding part 22 is slightly smaller than the heat dissipation hole 211.

[0034] Please see Figure 2 As shown, in some embodiments, exemplarily, the recessed portion 21 protrudes upward at the edge of the heat dissipation hole 211 to form a flange 212. By providing the flange 212, airflow can be guided. When the bottle warmer generates heat during operation, the hot air will be guided by the flange 212 to be discharged more orderly through the heat dissipation hole 211, and the cold air can also be replenished more smoothly, thereby forming good air convection, greatly enhancing the heat dissipation effect, and effectively improving the problem of excessively high internal temperature of the bottle warmer.

[0035] Please see Figure 3As shown, in some embodiments, the bottle warmer also includes a first connecting post 213 and a second connecting post 214. The first connecting post 213 is disposed on the base 20, and the second connecting post 214 is disposed on the recess 21. The circuit board assembly 50 is mounted on the first connecting post 213 and the second connecting post 214. The first connecting post 213 and the second connecting post 214 are used to connect the circuit board assembly 50, so that the circuit board assembly 50 and the base 20 are kept at a certain distance to avoid direct contact that would cause heat accumulation. This design enhances the air circulation around the circuit board assembly 50. Moreover, the heat dissipation hole 211 can better drive the air convection around the circuit board, accelerate the dissipation of heat on the circuit board assembly 50, further ensure the stable operation of the circuit board assembly 50, and reduce the probability of failure.

[0036] Please see Figure 3 and Figure 4 As shown, in some embodiments, for example, the support portion 31 is provided with multiple sets of through holes around the first through hole 311. Each set of through holes includes a second through hole 312 and a third through hole 313 arranged sequentially from the inside to the outside. This design can provide more uniform heat to the baby bottle and improve the heating effect.

[0037] In this embodiment, four sets of through holes are provided, and the four sets of through holes are arranged around the first through hole 311.

[0038] In this embodiment, the second through hole 312 is an oblong hole, and the third through hole 313 is an arc-shaped hole. There are two third through holes 313. It can be understood that the number of the second through holes 312 and the third through holes 313 can be set according to the actual situation.

[0039] Furthermore, a reinforcing rib 314 is provided at the bottom of the bearing part 31, which can improve the load-bearing capacity of the bearing part 31.

[0040] Please see Figure 3 As shown, in some embodiments, exemplarily, the bottom of the inner liner 30 is provided with an extension 32, and the heating assembly 40 includes a mounting plate 43, a heating plate 41, and a sealing ring 42. The mounting plate 43 is detachably connected to the inner liner 30, the outer wall of the heating plate 41 is provided with a mounting portion, the sealing ring 42 is installed between the inner liner 30 and the mounting plate 43, and the sealing ring 42 is located inside the extension 32. The inner wall of the sealing ring 42 is provided with a mounting groove adapted to the mounting portion. The heating plate 41 is connected to the inner liner 30 by cooperating with the mounting portion and the mounting groove on the sealing ring 42. The installation process is simple and convenient for users to disassemble and install when cleaning or replacing parts. At the same time, this close-fitting installation method ensures a stable connection between the heating assembly 40 and the inner liner 30, ensuring the stability of the bottle warmer during operation.

[0041] Please see Figure 1 and Figure 3 As shown, in some embodiments, the bottle warmer also includes a baby food cup 70, which includes a cup body 71 and a handle 72. The bottom of the cup body 71 is provided with a fifth through hole 711, and the side wall of the cup body 71 is provided with a sixth through hole 712. The handle 72 is provided on the cup body 71 and extends outward to the outer casing 10 of the main unit. By providing the baby food cup 70, baby food can be heated, which increases the functionality of the bottle warmer. Moreover, the fifth through hole 711 at the bottom of the cup body 71 and the sixth through hole 712 on the side wall of the cup body 71 can make the heat inside the bottle warmer more evenly transferred to the baby food cup 70, so that the baby food is heated more evenly and avoids local overheating or undercooling.

[0042] Optionally, a grip portion 721 is provided at the end of the handle 72 away from the cup body 71. The grip portion 721 is provided with anti-slip texture 722. The design of the grip portion 721 further conforms to ergonomics, allowing users to grip it more comfortably and effortlessly. The anti-slip texture 722 on the grip portion 721 significantly increases friction, effectively preventing slippage even when hands are sweaty or stained with milk or other liquids during the process of taking out and putting away the baby food cup 70, greatly improving the safety of use.

[0043] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
