Technical Field

[0001] This utility model relates to the field of baby bottle heating technology, specifically to an electric baby bottle. Background Technology

[0002] In existing bottle heating processes, the bottle is placed on a heating base, and after the base is powered on, the heating components (such as a heating plate or heating wire) of the base indirectly heat the liquid inside the bottle through the bottle. This method has slow heat transfer efficiency and a long heating time. A specific structure can be found in Chinese Patent No. ZL202323049461.1, which discloses a bottle warmer including a sleeve, a control panel, a heating component, and a temperature probe. The control panel contains a circuit board, and one end of the temperature probe is connected to the circuit board. The sleeve forms an open-top bottle placement cavity. The heating component is disposed within the sleeve and electrically connected to the circuit board. The device also includes a base, and the control panel is connected to the base. The base has a sleeve placement cavity, and the sleeve is placed within this cavity. The other end of the temperature probe extends into the bottle placement cavity. In summary, this bottle warmer has a heating component disposed within the sleeve, forming an open-top bottle placement cavity for holding the bottle. The sleeve and base are connected and assembled to form a heating base for holding the bottle. Utility Model Content

[0003] This utility model proposes an electric heating baby bottle. By setting an electric heating film on a heat-conducting bottom cover, which is located at the opening of the bottle's inner cavity, the bottle is electrically coupled to the power supply base when placed on the power supply base. After the power supply base is connected to a power source and powered on, the electric heating film heats up to transfer heat to the metal heat-conducting bottom cover. The heat-conducting bottom cover is in direct contact with the liquid, transferring heat upwards to the liquid. This results in high heat transfer efficiency and a short heating time.

[0004] An electric heating baby bottle designed for this purpose includes a bottle body detachably mounted on a power supply base. The bottle body has a heat-conducting bottom cover that serves as the bottom wall of the inner cavity of the bottle, an electric heating film for heating the bottle body, and an electrical connection assembly for conducting electricity. The electric heating film is disposed on the heat-conducting bottom cover and heats the bottle body when energized. The electrical connection assembly is electrically connected to the electric heating film. The bottle body is placed on the power supply base, and the electrical connection assembly is electrically connected to the power supply base, forming an electrically coupled connection structure between the bottle body and the power supply base.

[0005] The heat-conducting bottom cover is made of metal, such as titanium or food-grade stainless steel. The heat-conducting bottom cover is located at the end opening of the inner cavity of the bottle. The heat-conducting bottom cover and the bottle body form a water storage cavity. A temperature sensor is provided at the bottom of the heat-conducting bottom cover, and the temperature probe of the temperature sensor abuts against the heat-conducting bottom cover. The temperature sensor is electrically connected to the power connection assembly.

[0006] The heat-conducting bottom cover has a protrusion that extends downward toward the bottom of the heat-conducting bottom cover, and the temperature probe of the temperature sensor abuts against the protrusion.

[0007] The heating film has a corresponding relief groove on the protrusion to prevent contact between the heating film and the temperature sensor.

[0008] The bottle body is provided with a bracket for fixing the electrical connection assembly, and the bracket is provided with a limiting mounting groove for limiting the installation of each electrical connection terminal; the bracket is made of insulating material to prevent conductive contact between each electrical connection terminal.

[0009] The bottle body is provided with a positioning block, and the positioning block is provided with a limiting slot for limiting the installation bracket;

[0010] The lower part of the bottle body is provided with a lower cover, and the lower cover is provided with a clearance space at the conductive connection between the electrical assembly and the power supply base;

[0011] A mounting cavity is formed between the lower cap and the bottom of the bottle body to accommodate the bracket, the power connection assembly, the temperature sensor, and the positioning block; the bracket, the power connection assembly, the temperature sensor, and the positioning block are encapsulated within the mounting cavity.

[0012] The lower part of the bottle body is provided with a baffle, which extends downward toward the lower part of the bottle body, and the heat-conducting bottom cover and the electric heating film are limited on the inner side of the baffle.

[0013] The enclosure is provided with a first locking groove, the positioning block is provided with a second locking groove, and the inner cavity of the lower cover is provided with a locking rib. The first locking groove, the second locking groove and the locking rib are set in a one-to-one correspondence. The bottle body, the positioning block and the lower cover are assembled together, and the first locking groove and the second locking groove are respectively engaged with the locking rib.

[0014] The positioning block is equipped with a magnet, and the bottle is positioned and attached to the power supply base by the magnet.

[0015] A sealing element is provided at the assembly point between the lower cap and the bottle body, and a sealed connection is formed between the lower cap and the bottle body through the sealing element.

[0016] The lower cover has a groove, the power supply base has a positioning boss, and the power supply base has a battery compartment for installing batteries; the lower cover of the bottle is placed on the power supply base, and the positioning boss is limited in the groove.

[0017] The power supply base is provided with a conductive pin assembly that is electrically connected to the power connection assembly. The power connection assembly includes several power connection terminals, and the conductive pin assembly includes several conductive pins. Each power connection terminal is configured to correspond one-to-one with each conductive pin.

[0018] The power connection assembly includes a first power connection terminal and a second power connection terminal that are electrically connected to the heating film. The power connection assembly also includes a third power connection terminal and a fourth power connection terminal that are electrically connected to the temperature sensor.

[0019] The beneficial technical effects of this utility model are as follows:

[0020] By placing the heating film on the heat-conducting bottom cover, which is located at the opening of the bottle's inner cavity, the bottle is electrically coupled to the power supply base when placed on the power supply base. Once the power supply base is connected to a power source and energized, the heating film heats up, transferring heat to the metal heat-conducting bottom cover. The heat-conducting bottom cover is in direct contact with the liquid, transferring heat upwards to the liquid, resulting in high heat transfer efficiency and a short heating time. This effectively replaces the structure where the heating element is placed on a heating base. The heating film is relatively smaller than the heating element, effectively saving installation space at the bottom of the bottle.

[0021] A seal is provided at the assembly point between the lower cap and the bottle body to prevent external moisture from entering the mounting cavity between the lower cap and the bottle body, effectively protecting the electrical components between the lower cap and the bottle body.

[0022] The bottle is positioned and attached to the power supply base by magnets. The power supply base attracts the bottle through the magnetic interaction between two magnets, ensuring good contact between the bottle and the power supply base.

[0023] Each power terminal of the power connection assembly is mounted on a bracket, which is made of insulating material to prevent conductive contact between the power terminals and effectively prevent short circuits.

[0024] Because the positioning block and the bracket are close to the heating film, both the positioning block and the bracket are made of high-temperature resistant materials.

[0025] When the bottle body, positioning block, and lower cover are assembled, the engagement between the locking ribs and the locking grooves allows for easy positioning and assembly of the three components. No other accessories are required for positioning and assembly, simplifying the assembly structure and resulting in high overall assembly efficiency for the electric heating baby bottle.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0036] See Figures 1-8 The device includes a bottle body 1 that is detachably mounted on a power supply base 2. The bottle body 1 is provided with a heat-conducting bottom cover 3 that serves as the bottom wall of the inner cavity of the bottle body 1, an electric heating film 4 for heating the bottle body 1, and an electrical connection assembly 5 for conducting electricity. The electric heating film 4 is disposed on the heat-conducting bottom cover 3 and heats the bottle body 1 when energized. The electrical connection assembly 5 is electrically connected to the electric heating film 4. The bottle body 1 is placed on the power supply base 2, and the electrical connection assembly 5 is electrically connected to the power supply base 2. The electrical connection assembly 5 forms an electrically coupled connection structure between the bottle body 1 and the power supply base 2.

[0037] By placing the heating film 4 on the heat-conducting bottom cover 3, which is located at the opening of the inner cavity of the bottle body 1, the bottle body 1 and the power supply base 2 are electrically coupled when the bottle body 1 is placed on the power supply base 2. After the power supply base 2 is connected to the power source and powered on, the heating film 4 heats up to transfer heat to the metal heat-conducting bottom cover 3. The heat-conducting bottom cover 3 is in direct contact with the liquid, transferring heat upwards to the liquid, resulting in high heat transfer efficiency and short heating time. This effectively replaces the structure of placing the heating component on the heating base. This utility model places the heating film 4 on the heat-conducting bottom cover 3 of the bottle body. The volume of the heating film 3 is relatively small compared to the heating element, effectively saving installation space at the bottom of the bottle 1.

[0038] The heat-conducting bottom cover 3 is made of metal, such as titanium or food-grade stainless steel. The heat-conducting bottom cover 3 is located at the end opening of the inner cavity of the bottle body 1. The heat-conducting bottom cover 3 and the bottle body 1 form a water storage cavity 6. A temperature sensor 7 is provided at the lower part of the heat-conducting bottom cover 3. The temperature probe of the temperature sensor 7 abuts against the heat-conducting bottom cover 3. The temperature sensor 7 is electrically connected to the power connection assembly 5.

[0039] In this embodiment, the heat-conducting bottom cover 3 and the bottle body 1 are integrated by injection molding. This can be understood as placing the heat-conducting bottom cover 3 on the mold cavity of the mold used to manufacture the bottle body 1. When the bottle body 1 is injection molded, the heat-conducting bottom cover 3 is fixed on the end opening of the inner cavity of the bottle body 1, and the end opening is close to the bottom of the bottle body 1.

[0040] The heat-conducting bottom cover 3 is provided with a protrusion 8, which extends downward toward the bottom of the heat-conducting bottom cover 3, and the temperature probe of the temperature sensor 7 abuts against the protrusion 8.

[0041] The heating film 4 has a recessed groove 9 corresponding to the protrusion 8 to prevent contact between the heating film 4 and the temperature sensor 7. Since the temperature sensor 7 does not contact the heating film 4, it effectively detects the bottom temperature of the heat-conducting bottom cover 3 of the bottle 1, which is equivalent to detecting the liquid temperature.

[0042] The electric heating film 4 is fixed to the heat-conducting bottom cover 3 by welding.

[0043] In this embodiment, the temperature sensor 7 is an NTC temperature sensor, and the two pins of the temperature sensor 7 are in conductive contact with the corresponding power terminals.

[0044] The bottle body 1 is provided with a bracket 10 for fixing the electrical connection assembly 5. The bracket 10 is provided with a limiting mounting groove 11 for limiting the installation of each electrical connection terminal. The bracket 10 is made of insulating material to prevent conductive contact between each electrical connection terminal.

[0045] In this embodiment, the heating film 4 is provided with a first conductive terminal 34 and a second conductive terminal 35 that form conductive contact with the electrical terminals of the electrical assembly 5. The bracket 10 is provided with fixing slots corresponding to the first conductive terminal 34 and the second conductive terminal 35. The first conductive terminal 34 and the second conductive terminal 35 respectively form conductive contact with the corresponding electrical terminals through leads.

[0046] The bottle body 1 is provided with a positioning block 12, and the positioning block 12 is provided with a limiting slot 13 for limiting the mounting bracket 10;

[0047] The lower part of the bottle body 1 is provided with a lower cover 14, and the lower cover 14 is provided with a clearance 15 at the conductive connection between the electrical assembly 5 and the power supply base 2;

[0048] The lower cover 14 and the bottom of the bottle body 1 form an installation cavity 16 for accommodating the bracket 10, the power connection assembly 5, the temperature sensor 7 and the positioning block 12; the bracket 10, the power connection assembly 5, the temperature sensor 7 and the positioning block 12 are encapsulated in the installation cavity 16.

[0049] The lower part of the bottle body 1 is provided with a baffle 17, which extends downward toward the lower part of the bottle body 1. The heat-conducting bottom cover 3 and the electric heating film 4 are limited on the inner side of the baffle 17 to prevent the heat from spreading outward to the outside of the baffle 17 when the electric heating film 4 is heated, and to ensure that the heat is concentrated and transferred upward to the heat-conducting bottom cover 3.

[0050] The enclosure 17 is provided with a first locking groove 18, the positioning block 12 is provided with a second locking groove 19, and the inner cavity of the lower cover 14 is provided with a locking rib 20. The first locking groove 18, the second locking groove 19 and the locking rib 20 are set in a one-to-one correspondence. The bottle body 1, the positioning block 12 and the lower cover 14 are assembled together, and the first locking groove 18 and the second locking groove 19 are respectively engaged with the locking rib 20.

[0051] In this embodiment, the inner cavity of the lower cover 14 is provided with several locking ribs 20.

[0052] The positioning block 12 is equipped with a magnet 21, and the bottle body 1 is positioned and attached to the power supply base 2 by the magnet 21.

[0053] In this embodiment, the positioning block 12 is provided with a mounting groove for mounting the magnet 21.

[0054] A sealing element 31 is provided at the assembly point between the lower cover 14 and the bottle body 1, and a sealed connection is formed between the lower cover 14 and the bottle body 1 through the sealing element 31.

[0055] The lower cover 14 is provided with a groove 22, the power supply base 2 is provided with a positioning boss 23, and the power supply base 2 is provided with a battery compartment 25 for installing the battery 24; the lower cover 14 of the bottle body 1 is placed on the power supply base 2, and the positioning boss 23 is limited on the groove 22.

[0056] The power supply base 2 is provided with a conductive pin assembly 26 that is electrically connected to the power connection assembly 5. The power connection assembly 5 includes a number of power connection terminals, and the conductive pin assembly 26 includes a number of conductive pins. Each power connection terminal is configured to correspond one-to-one with each conductive pin.

[0057] In this embodiment, the power supply base 2 has a clearance hole for each conductive pin, and each conductive pin extends upward through the clearance hole. Each conductive pin can elastically extend and retract on the corresponding clearance hole via a spring. When the bottle 1 is placed on the power supply base 2, the conductive pin retracts into the clearance hole and compresses the spring. After the spring returns to its original position, the conductive pin effectively forms elastic contact with the power terminal, ensuring the electrical coupling connection between the power supply base 2 and the bottle 1.

[0058] In this embodiment, the lower cover 14 and the bottle body 1 are fixedly connected by screws or by ultrasonic welding to form an inseparable whole between the lower cover 14 and the bottle body 1.

[0059] In this embodiment, the enclosure 17 of the bottle body 1 is provided with a connecting post 32 extending toward the lower cover 14, and the connecting post 32 is provided with an inner cavity for inserting fasteners such as screws; the lower cover 14 is provided with mounting holes 33 for inserting fasteners such as screws corresponding to the connecting post 32.

[0060] The power connection assembly 5 includes a first power connection terminal 27 and a second power connection terminal 28 that are electrically connected to the heating film 4. The power connection assembly 5 also includes a third power connection terminal 29 and a fourth power connection terminal 30 that are electrically connected to the temperature sensor 7.

[0061] In this embodiment, each power terminal is arranged linearly on the bracket 10.
