[0001] This utility model relates to the field of small household appliance technology, and in particular to bottle warmers. Background Technology
[0002] Bottle warmers can quickly heat milk to a suitable temperature, reducing the time and effort parents need to spend on feeding.
[0003] When a bottle warmer heats milk, it simultaneously rotates the bottle to help mix the milk's components and ensure more even heating, preventing localized overheating that could destroy the milk's nutrients. To ensure stable clamping during bottle rotation, the bottle warmer is secured circumferentially by clamping the bottle's side. While this provides stable clamping, the handle on the side of the bottle can easily interfere with the warmer, significantly limiting the types of bottles it can hold.
[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0019] A further technical solution is that, around the rotation axis of the fixed base, a plurality of first vent holes are opened on the fixed base.
[0020] The beneficial technical effects of this utility model are as follows:
[0021] (1) The bottle warmer of this utility model delivers warm air to the bottle through a fan and a heater to heat the bottle. The warm air heating method ensures that the milk is heated evenly, avoiding local overheating that could affect the nutritional components of the milk powder. Moreover, warm air heating is faster than the traditional water bath heating method, reducing heating time. At the same time, the fixed base is rotatably mounted on the base and connected to a drive mechanism. The bottle is continuously rotated while heating, further ensuring that the milk is heated evenly and preserving the nutritional components of the milk to the greatest extent. In addition, the bottle warmer holds the bottle in place with clamps, and an elastic element is provided between the clamps and the fixed base to support the clamps. This allows the clamps to hold the bottle stably even when there is a large gap between the clamps and the fixed base. Since the clamps only contact a few points on the bottle, they do not interfere with the bottle handle. At the same time, the gap between the clamps and the fixed base prevents the bottle handle from interfering with the fixed base, allowing the bottle warmer to hold bottles with handles, greatly expanding the bottle warmer's holding capacity.
[0022] (2) Further, a first limiting protrusion is provided on the inner liner and a second limiting protrusion is provided on the clamping part, and the position of the elastic element is fixed by the first limiting protrusion and the second limiting protrusion.

[0032] Figure 1 A vertical cross-sectional view of the bottle warmer of this utility model is shown. Figure 2 The diagram shows the mating structure of the fixing base and the inner liner in the bottle warmer of this utility model. Figure 3 An exploded view of the bottle clamp and inner liner in the bottle warmer of this invention is shown. Please refer to... Figure 1 , Figure 2 and Figure 3The bottle warmer includes a base 1, a mounting base 3, and a bottle clamp 5. The base 1 has a warm air chamber 11 inside. A fan 111 and a heater 112 are installed inside the warm air chamber 11. Warm air is delivered to the bottle through the fan 111 and heater 112 to heat the bottle. This warm air heating method ensures even heating of the milk, avoiding localized overheating that could affect the nutritional components of the formula. Furthermore, warm air heating is faster than traditional water bath heating, reducing heating time. The mounting base 3 is rotatably mounted on the base 1. The mounting base 3 has a mounting cavity 32 and a first vent 31. The first vent 31 connects the mounting cavity 32 and the warm air chamber 11. The mounting base 3 is connected to a drive mechanism, which can be a motor. The bottle is continuously rotated while heating, further ensuring even heating of the milk and preserving its nutritional components to the greatest extent. The bottle clamp 5 is mounted on the mounting base 3. A gripper 51 extends from the bottle clamp 5 and is located within the mounting cavity 32. At least three grippers 51 are provided, and the three grippers 51 are evenly arranged around the rotation axis of the fixed base 3. Each gripper 51 includes a connecting part 511 and a clamping part 512. The connecting part 511 connects the clamping part 512 and the bottle clamp 5. An elastic element 6 is provided between the clamping part 512 and the fixed base 3. The bottle is clamped by the grippers 51 within the mounting cavity 32. The bottle warmer holds and fixes the bottle by the grippers 51, and the elastic element 6 between the grippers 51 and the fixed base 3 supports the grippers 51. This ensures that even with a large gap between the grippers 51 and the fixed base 3, the grippers 51 can still stably hold the bottle. Since the grippers 51 only contact a few points on the bottle, they do not interfere with the bottle handle. Simultaneously, the gap between the grippers 51 and the fixed base 3 prevents interference between the bottle handle and the fixed base 3, allowing the bottle warmer to hold bottles with handles, greatly expanding the bottle warmer's clamping capacity.
[0033] In this embodiment, a flange 54 extends circumferentially from the upper end of the bottle clip 5. When the bottle clip 5 is placed on the fixing base 3, the lower surface of the flange 54 contacts the upper surface of the fixing base 3, thereby restricting the position between the bottle clip 5 and the fixing base 3 and increasing the contact area between the bottle clip 5 and the fixing base 3.
[0034] Please refer to Figure 1 and Figure 3 An inner liner 4 is also provided inside the mounting cavity 32. The inner liner 4 is positioned between the fixing base 3 and the bottle clamp 5. A first limiting protrusion 41 is provided on the inner liner 4 to connect to the elastic element 6. A second limiting protrusion 513 extends from the side of the clamping part 512 near the fixing base 3. The second limiting protrusion 513 connects to the elastic element 6. In this embodiment, the elastic element 6 is a spring, with its two ends respectively sleeved on the first limiting protrusion 41 and the second limiting protrusion 513. The position of the elastic element 6 is fixed by the first limiting protrusion 41 and the second limiting protrusion 513.
[0035] Preferably, a lower retaining groove 42 is provided on the side of the inner liner 4 near the bottle clip 5. A lower snap-fit part 53 extends upward from the bottle clip 5 and engages with the lower retaining groove 42. The lower snap-fit part 53 snaps into the lower retaining groove 42, securing the inner liner 4 and the bottle clip 5. This snap-fit connection is easy to assemble and disassemble, facilitating cleaning and maintenance of the bottle warmer, thereby reducing bacterial growth and improving the user experience.
[0036] More preferably, a second vent 43 is provided on the inner liner 4. When the inner liner 4 is installed in the mounting cavity 32, the second vent 43 is aligned with the first vent 31. The provision of the second vent 43 facilitates the direct passage of warm air from the heating cavity 2 through the inner liner 4 onto the bottle for heating.
[0037] Please refer to Figure 1 and Figure 4 The bottle clamp 5 is also equipped with a cover plate 7. A limiting hole 71 is provided on the cover plate 7. The axis of the limiting hole 71 is aligned with the rotation axis of the fixing base 3. When the bottle is placed in the mounting cavity 32, the bottle passes through the limiting hole 71. Through the limiting hole 71, the cover plate 7 further supports and fixes the position of the bottle, enhancing the stability of the bottle when it rotates.
[0038] Preferably, a plurality of deformation grooves 72 are radially formed on the cover plate 7 around the rotation axis of the fixing base 3. The deformation grooves 72 are connected to the limiting hole 71. By forming deformation grooves 72 on the cover plate 7, the strength of the cover plate 7 at the limiting hole 71 is reduced, making it easier for the cover plate 7 at the limiting hole 71 to deform and fit onto the baby bottle.
[0039] More preferably, a limiting ring 73 is provided along the lower surface of the cover plate 7. When the cover plate 7 is placed on the bottle clamp 5, the limiting ring 73 is sleeved on the bottle clamp 5, limiting the positional relationship between the cover plate 7 and the bottle clamp 5.
[0040] Please refer to Figure 1 , Figure 2 and Figure 3 A gap is left between the base 1 and the fixed seat 3 to form a heating chamber 2. An air outlet 113 is provided on the base 1. The air outlet 113 connects the heating chamber 2 and the warm air chamber 11. The first vent 31 connects to the heating chamber 2. The heating chamber 2 is arranged around the fixed seat 3 so that the warm air in the heating chamber 2 can evenly heat the baby bottle in the fixed seat 3 in a circumferential manner.
[0041] Preferably, a plurality of first vent holes 31 are provided on the fixing base 3 around the rotation axis of the fixing base 3. The arrangement of multiple first vent holes 31 allows the warm air in the heating chamber 2 to enter the mounting chamber 32 evenly in the circumferential direction, so that the milk in the bottle is heated more evenly and the nutritional components of the milk are preserved to the greatest extent.
[0042] More preferably, an upper retaining groove 33 is formed on the cavity of the mounting cavity 32. The upper retaining groove 33 includes a vertical section 331 and a limiting section 332. The vertical section 331 connects to the upper surface of the fixing base 3. The limiting section 332 is set at an angle to the vertical section 331. An upper buckle 52 extends from the bottle clip 5 and engages with the upper retaining groove 33. The upper buckle 52 enters the upper retaining groove 33 along the vertical section 331 and then slides into the limiting section 332. Because the limiting section 332 is set at an angle to the vertical section 331, the upper buckle 52 is restricted from moving up and down by the limiting section 332, thus engaging the bottle clip 5 and the fixing base 3.
[0043] The specific workflow of this utility model is as follows:
[0044] When warming the bottle, insert it into the mounting cavity 32 along the limiting hole 71. When the bottle's shape is larger than the diameter of the limiting hole 71, the bottle presses against the cover plate 7, and the limiting hole 71 of the cover plate 7 expands along the deformation groove 72. At the same time, the part of the bottle inserted into the mounting cavity 32, the gripping part 512 of the claw 51 contacts the bottle. The elastic force of the claw 51 itself and the elastic force of the elastic element 6 jointly support the gripping part 512, so that the gripping part 512 contacts and abuts against the bottle. Multiple claws 51 work together to fix the bottle in a horizontal position. Until the bottle contacts the bottom of the mounting cavity 32, the bottle clamping is completed. Then, the fan 111, heater 112 and drive mechanism are started. The fan 111 draws air along the warm air cavity 11. The drawn air is heated by the heater 112 and blown onto the surface of the bottle to heat the bottle. At the same time, the drive mechanism drives the fixed base 3 to rotate, and the rotating fixed base 3 drives the bottle to rotate synchronously, so that the warm air blows evenly on all sides of the bottle, and the milk in the bottle is heated evenly.
[0045] 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.
[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
