Abstract
Description
Technical Field
[0001] This utility model relates to the field of bottle warmer technology, and in particular to a bottle warmer that is easy to clean. Background Technology
[0002] As a baby product, the hygiene of a bottle warmer directly affects a baby's health. If milk residue, food scraps, or bacteria remain inside or outside the bottle warmer, these microorganisms may multiply and contaminate subsequent milk, causing the baby to ingest unsanitary food, which can lead to gastrointestinal discomfort, infection, or other health problems.
[0003] Therefore, cleaning bottle warmers is extremely important. The bottle holder, which directly contacts and holds the bottle, is the most prone to bacterial growth and requires frequent cleaning. However, to heat the bottle inside the holder, the outer side of the holder directly contacts the heating chamber of the bottle warmer. Since the heating chamber is a sealed structure and difficult to disassemble, the outer surface of the holder is difficult to clean, easily leading to bacterial growth and serious hygiene problems.
[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

[0013] A further technical solution is that the driven wheel is connected to the base via a bearing; the driven wheel is connected to the fixed seat via a screw.
[0014] A further technical solution is that a temperature control probe is installed inside the mounting cavity.
[0015] A further technical solution is that multiple first vent holes are provided, and the multiple first vent holes are evenly arranged around the rotation axis of the fixed base.
[0016] A further technical solution is that the cross-section of the base near the end of the shroud is contracted to form a contracted section; the shroud is fitted onto the contracted section; the shroud and the contracted section are interference-fitted.
[0017] A further technical solution is that a first air outlet is provided on the base, which connects the warm air chamber and the air duct; a second air outlet is provided on the air cover, which connects the air duct and the heating chamber; both the first air outlet and the second air outlet are formed by a combination of several small-diameter holes.
[0018] A further technical solution includes a bottle clamp; the annular bottle clamp is disposed within the mounting cavity; and the gripper is disposed on the inner side of the bottle clamp.
[0019] A further technical solution is that the gripper includes a connecting part and a clamping part; the connecting part is connected to the bottle clamp; and a gap is left between the clamping part and the bottle clamp.
[0020] A further technical solution is that a second vent hole is provided on the bottle clamp; when the bottle clamp is placed in the mounting cavity, the second vent hole is aligned with the first vent hole.
[0021] The beneficial technical effects of this utility model are as follows:
[0022] (1) The easy-to-clean 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. Furthermore, warm air heating is faster than traditional water bath heating, reducing heating time. Simultaneously, the fixed base is rotatably mounted on the base and connected to a drive mechanism. The bottle rotates continuously while heating, further ensuring even heating of the milk and preserving its nutritional components to the maximum extent. In addition, the fan cover and base are separate units, facilitating the removal and installation of the fan cover. After removing the fan cover, the outer surface of the fixed base can be easily cleaned, ensuring the cleanliness of the bottle warmer and preventing bacterial growth.
[0023] (2) Furthermore, the motor and the mounting base are connected by a belt drive. Belt drive is smooth and low-noise, which is especially important for bottle warmers that require a quiet environment, as it can avoid disturbing the baby while they are sleeping. At the same time, the belt will slip on the drive pulley and the driven pulley, which can play an overload protection role, thereby extending the service life of the bottle warmer.
[0024] (3) Furthermore, both the first and second air outlets are composed of several small-diameter holes. The multiple small holes allow the airflow to be more dispersed and gentle, improving the comfort of the air delivery. Then, the warm air is blown more evenly onto the bottle to heat the milk, making the heating of the milk more uniform. At the same time, the multiple small holes disperse the airflow into multiple streams, which reduces the speed and impact force of each airflow, thereby reducing the generation of noise.

Figure 2 The diagram shows a vertical cross-sectional view of the warm air chamber in the easy-to-clean bottle warmer of this invention. Figure 3 This diagram shows a vertical cross-sectional view of the drive mechanism in the easy-to-clean bottle warmer of this invention. Please refer to... Figure 1 , Figure 2 and Figure 3The easy-to-clean bottle warmer includes a base 1, a mounting base 3, and a fan shroud 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. The mounting base 3 is rotatably mounted on the base 1. The mounting base 3 is connected to a drive mechanism 2. An upward-facing mounting cavity 33 is opened on the mounting base 33. A clamp 61 is installed inside the mounting cavity 33. The bottle is continuously rotated during heating to further ensure even heating of the milk and maximize the retention of its nutrients. The fan shroud 5 is mounted on the base 1 and fitted onto the mounting base 3. A gap is left between the fan shroud 5 and the mounting base 3 to form a heating chamber 4. The fan shroud 5 and the base 1 are separate components, facilitating the installation and removal of the fan shroud 5. After removing the fan shroud 5, the outer surface of the mounting base 3 can be easily cleaned, ensuring the cleanliness of the bottle warmer and preventing bacterial growth. An air duct 51 is opened inside the fan shroud 5. The air duct 51 connects the warm air chamber 11 and the heating chamber 4. A first vent 31 is provided on the mounting base 3. The first vent 31 connects the heating chamber 4 and the mounting chamber 33. The baby bottle is placed in the mounting chamber 33 and held by the gripper 61. Warm air is delivered to the baby bottle through the fan 111 and the heater 112 to heat the bottle. The warm air heating method ensures that the milk is heated evenly, avoiding local overheating that may affect the nutritional components of the milk powder. Moreover, warm air heating is faster than the traditional water bath heating method, reducing heating time.
[0033] In this embodiment, the heater 112 is installed at the air outlet of the fan 111. The airflow blown out by the fan 111 is heated by the heater 112 before flowing into the air duct 51.
[0034] Please refer to Figure 3 The drive mechanism 2 includes a motor 21 and a transmission assembly 22. The transmission assembly 22 includes a drive pulley 221 located at the output end of the motor 21, a driven pulley 223 connected to the fixed base 3, and a belt 222 connecting the drive pulley 221 and the driven pulley 223. Specifically, the driven pulley 223 is connected to the base 1 via a bearing 224. The driven pulley 223 is screwed to the fixed base 3. Belt drive provides smooth operation and low noise, which is especially important for bottle warmers that require a quiet environment, preventing disturbance to the baby while sleeping. Simultaneously, the belt 222 can slip on the drive pulley 221 and the driven pulley 223, providing overload protection and extending the lifespan of the bottle warmer.
[0035] Please refer to Figure 2 A temperature control probe 32 is installed inside the mounting cavity 33. This temperature control probe 32 can be a commercially available Omega PR-25CU type temperature control probe 32.
[0036] Preferably, multiple first vent holes 31 are provided, and the multiple first vent holes 31 are evenly arranged around the rotation axis of the fixed base 3. Providing multiple first vent holes 31 allows the warm air in the heating chamber 4 to enter the fixed base 3 evenly to heat the baby bottle, making the heating of the milk more uniform.
[0037] Please refer to Figure 1 and Figure 2 The cross-section of the base 1 near the fan shroud 5 narrows to form a narrow section 12. The fan shroud 5 is fitted onto the narrow section 12. The fan shroud 5 and the narrow section 12 are interference-fitted. The interference fit between the fan shroud 5 and the base 1 facilitates the disassembly and assembly of the fan shroud 5 and the base 1, making it easy to clean the outer surface of the fixing seat 3, ensuring the cleanliness of the bottle warmer and preventing bacterial growth.
[0038] In some embodiments, a first air outlet 113 is provided on the base 1, which connects to the warm air chamber 11 and the air duct 51. A second air outlet 52 is provided on the fan cover 5, which connects to the ventilation duct 51 and the heating chamber 4. Both the first air outlet 113 and the second air outlet 52 are formed by a combination of several small-diameter holes. The multiple small holes allow the airflow to be more dispersed and gentle, improving the comfort of the airflow. Then, the warm air is blown more evenly onto the bottle to heat the milk, making the heating of the milk more uniform. At the same time, the multiple small holes disperse the airflow into multiple streams, reducing the speed and impact of each airflow, thereby reducing noise generation.
[0039] Please refer to Figure 1 and Figure 3 It also includes a bottle clamp 6. The annular bottle clamp 6 is disposed within the mounting cavity 33, and the bottle clamp 6 is press-fitted with the fixing base 3. The grippers 61 are disposed on the inner side of the bottle clamp 6. Preferably, three grippers 61 are evenly arranged circumferentially to stably hold the bottle. At the same time, the bottle clamp 6 and the fixing base 3 are separately disposed, which facilitates the removal of the bottle clamp 6 and the cleaning and maintenance of the bottle clamp 6 and the fixing base 3 respectively.
[0040] Preferably, the gripper 61 includes a connecting portion 611 and a clamping portion 612. The connecting portion 611 connects to the bottle clamp 6, and a gap is left between the clamping portion 612 and the bottle clamp 6. The gap between the clamping portion 612 and the bottle clamp 6 provides more deformation space for the clamping portion 612, allowing the bottle clamp 6 to hold and fix bottles of more sizes. At the same time, the gap between the clamping portion 612 and the bottle clamp 6 can accommodate the bottle handle. This allows the bottle warmer of this application to stably fix bottles with handles.
[0041] More preferably, a second vent 62 is provided on the bottle clip 6. When the bottle clip 6 is set in the mounting cavity 33, the second vent 62 is aligned with the first vent 31. The second vent 62 allows the warm air in the heating cavity 4 to pass directly through the bottle clip 6 and blow onto the bottle, thus heating the bottle thoroughly.
[0042] The specific workflow of this utility model is as follows:
[0043] When heating the baby bottle, the bottle is first placed in the mounting cavity 33, held by multiple grippers 61 and supported by the fixing base 3. Then, the fan 111, heater 112, and motor 21 are started. The fan 111 draws airflow, which is heated by the heater 112 and then blows onto the baby bottle along the warm air cavity 11, the first air outlet 113, the air duct 51, the second air outlet 52, the heating cavity 4, the first vent 31, and the second vent 62, heating the baby bottle. At the same time, the motor 21 drives the fixing base 3 to rotate continuously through the drive wheel 221, belt 222, and driven wheel 223, thereby driving the baby bottle to rotate continuously. The rotating baby bottle causes the warm air to blow onto the circumferential surface of the baby bottle, making the heating of the baby bottle more even.
[0044] When cleaning the bottles, you can remove the fan cover 5 from the base 1, and then you can directly clean the outer surface of the mounting base 3. Alternatively, you can first remove the bottle clip 6, and then clean the inner surface of the bottle clip 6 or the mounting base 3, and then remove the mounting base 3, at which point you can clean the entire mounting base 3.
[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.
