[0034] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0035] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0036] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0037] To address the slow heating issues of various existing milk warmers, the applicant first developed an inverted milk warmer. The bottle is mounted upside down on the portable milk warmer, with the bottle opening facing downward. The portable milk warmer directly heats the liquid in the bottle, resulting in faster heating. However, with this setup, the applicant discovered that when the bottle is mounted upside down on the warmer, with the bottle opening facing downward, the liquid in the bottle moves toward the bottle opening under the influence of gravity. The heating element in the milk warmer is connected to the bottle opening to directly heat the liquid in the bottle. After heating is complete, the user needs to invert the entire milk warmer, including the bottle, so that the bottle opening faces upward, and then separate the warmer from the bottle.

[0038] The problem with this operation is that the milk warmer, the milk bottle and the liquid in the milk bottle are heavy when stacked together, which is inconvenient for users to operate.

[0039] Therefore, the present invention further provides a new improvement, by arranging the power supply seat and the heating seat into a detachable structure, which makes it convenient for users to disassemble or assemble the milk bottle before and after heating, thereby improving the convenience of using the milk warmer.

[0040] Reference below Figures 1-11 The milk warmer 100 according to an embodiment of the present invention will be described.

[0041] Example 1

[0042] like Figure 1-Figure 3 As shown, this embodiment provides a milk warmer 100 including a power supply seat 1, a heating seat 2 and a limiting structure 3.

[0043] like Figure 1 and Figure 3 As shown, the heating seat 2 can be detachably mounted on the power supply seat 1. Specifically, as Figure 5 As shown, the power supply base 1 has a mounting cavity 11, a socket 12 communicating with the mounting cavity 11, and a first conductive portion 13 disposed in the mounting cavity 11. Figure 1 and Figure 7As shown, the heating base 2 further includes an insertion section 221 and a second conductive portion 23 disposed on the insertion section 221. The insertion section 221 is inserted into the mounting cavity 11 via the socket 12 to electrically connect the first conductive portion 13 and the second conductive portion 23. The limiting structure 3 includes a first limiting structure 31 and a second limiting structure 32. The first limiting structure 31 is disposed within the mounting cavity 11, and the second limiting structure 32 is disposed on the insertion section 221. The first limiting structure 31 and the second limiting structure 32 are detachably connected, and the limiting structure 3 is used to fix the relative position of the insertion section 221 and the mounting cavity 11.

[0044] When the power supply base 1 and the heating base 2 are assembled in place, the limiting structure 3 can fix the relative position between the power supply base 1 and the heating base 2, thereby improving the stability and reliability of the assembly connection and electrical connection between the heating base 2 and the power supply base 1. Figure 2 and Figure 3 As shown, the heating base 2 is provided with a connecting portion 210 connected to the bottle mouth of the feeding bottle 200, and the liquid in the feeding bottle 200 flows through the bottle mouth to the heating base 2. The heating base 2 directly heats the liquid in the feeding bottle 200 without passing through the bottle body of the feeding bottle 200, which has higher heating efficiency.

[0045] The milk warmer 100 provided in this embodiment has the following advantages over the prior art: (1) when the heating seat 2 is separated from the power supply seat 1, the heating seat 2 can be disassembled and assembled with the bottle mouth of the milk bottle 200 alone. When the bottle mouth of the milk bottle 200 is inverted, there is no need to move the power supply seat 1, which improves the convenience of use; (2) the cooperation between the plug-in section 221 and the socket 12 can prompt and locate the separation and assembly between the heating seat 2 and the power supply seat 1, thereby improving the convenience of disassembly and assembly between the heating seat 2 and the power supply seat 1; (3) the cavity wall of the installation cavity 11 can prevent the plug-in section 221 from moving during the insertion and removal of the installation cavity 11, thereby improving the stability and reliability of the connection between the heating seat 2 and the power supply seat 1; (4) the limiting structure 3 can fix the relative position between the power supply seat 1 and the heating seat 2, and the conduction between the first conductive part 13 and the second conductive part 23 is not easily disconnected, thereby improving the stability and reliability of the electrical connection between the heating seat 2 and the power supply seat 1, and further improving the stability and reliability of the assembly connection between the heating seat 2 and the power supply seat 1.

[0046] like Figure 2 、 Figure 7 and Figure 8As shown, further, the plug-in section 221 is constructed as a columnar structure. Correspondingly, the socket 12 and the installation cavity 11 are matched with the columnar structure. The specific operation is: when the plug-in section 221 is constructed as a prismatic cavity, the installation cavity 11 is a prismatic cavity or a cylindrical cavity, and the outline of the socket 12 is polygonal or circular. When the plug-in section 221 is constructed as a cylindrical cavity, the installation cavity 11 is a prismatic cavity or a cylindrical cavity, and the outline of the socket 12 is polygonal or circular. Thereby, the stability and reliability of the disassembly and assembly between the heating seat 2 and the power supply seat 1 are further improved,

[0047] In a specific example, when the plug-in section 221 is cylindrical, the installation cavity 11 is a cylindrical cavity, and the outline of the socket 12 is circular.

[0048] like Figure 2 、 Figure 5-Figure 7 As shown, the first limiting structure 31 and the second limiting structure 32 are engaged or magnetically engaged. When the heating base 2 is installed in place, the first conductive portion 13 and the second conductive portion 23 are electrically connected. Therefore, it can be seen that the first limiting structure 31 and the second limiting structure 32 cooperate to limit the relative movement between the heating base 2 and the power supply base 1, thereby playing a positioning role.

[0049] like Figure 5-Figure 8 As shown, in some specific examples, the first limiting structure 31 is arranged on the cavity wall 111 of the installation cavity 11, and the first conductive part 13 is arranged at the bottom of the installation cavity 11; the second limiting structure 32 is arranged on the side surface of the plug-in section 221, and the second conductive part 23 is arranged on the end face of the plug-in section 221 away from the connecting part 210.

[0050] like Figure 5-Figure 7 As shown, a slide groove 1111 is further provided on the cavity peripheral wall 111, and a slider 2212 is further provided on the side surface of the plug section 221. The slide groove 1111 and the slider 2212 cooperate with each other in a guiding manner. A transition opening 1112 is also provided on the cavity peripheral wall 111 for connecting the socket 12 and the slide groove 1111. The slider 2212 can be detachably disposed in the slide groove 1111 through the transition opening 1112. The guiding cooperation between the slider 2212 and the slide groove 1111 further reduces the movement of the plug section 221 during assembly and disassembly with the installation cavity 11, thereby improving the stability and reliability of assembly and disassembly.

[0051] like Figure 5-Figure 7 As shown, further, the first limiting structure 31 is configured as a convex structure and is provided on the slide groove 1111, and the second limiting structure 32 is configured as a concave structure and is provided on the slider 2212. Such a configuration is conducive to avoiding interference between the slider 2212 and the transition opening 1112, further improving the convenience of installation.

[0052] Example 2

[0053] This embodiment is basically the same as the above embodiment, with the difference that: the number of sliders 2212 is one, and the number of transition openings 1112 is one; or, the sliders 2212 include multiple sliders, at least one slider 2212 is a positioning slider 2212 and its size is different from that of other sliders 2212; the transition openings 1112 include multiple transition openings 1112, at least one transition opening 1112 is a fool-proof positioning opening 1113 and its size is different from that of other transition openings 1112, and the transition openings 1112 are arranged in a one-to-one correspondence with the sliders 2212.

[0054] In one possible application scenario, to save production and manufacturing costs, only one first conductive portion 13 is provided on the power supply base 1, and only one second conductive portion 23 is provided on the heating base 2. In this case, it is difficult for the user to accurately determine the correct installation position between the power supply base 1 and the heating base 2. That is, when the user directly plugs the heating base 2 into the power supply base 1, without any prompts, it is difficult for the user to align the first conductive portion 13 with the second conductive portion 23 and conduct electricity at one time.

[0055] To solve the above problem, in some optional examples, the number of sliders 2212 is one, the number of transition openings 1112 is one, and the slider 2212 enters the slide groove 1111 only through the unique transition opening 1112, and the assembly position is prompted by the limiting structure 3. The transition opening 1112 is the entrance of the slider 2212, that is, the starting point of the stroke of the slider 2212, and the limiting structure 3 is the end point of the stroke of the slider 2212. Thus, the starting point of the stroke of the slider 2212 is uniquely determined, and the first conductive part 13 and the second conductive part 23 are configured to be conductive when the slider 2212 slides to the end point of the stroke in the slide groove 1111, thereby achieving: when the user directly plugs the heating seat 2 into the power supply seat 1, without any prompts, the user can align and connect the first conductive part 13 and the second conductive part 23 at one time.

[0056] In an optional further embodiment, the sliders 2212 include multiple sliders 2212, one of which is a positioning block 2213 and has different dimensions from the other sliders 2212; the transition openings 1112 include multiple transition openings 1112, one of which is a foolproof positioning opening 1113 and has different dimensions from the other transition openings 1112. During use, the positioning block 2213 is aligned with the foolproof positioning opening 1113 before installation.

[0057] In an optional further embodiment, the sliders 2212 include multiple sliders of different sizes, the transition openings 1112 include multiple sliders of different sizes, and the sliders 2212 are arranged in a one-to-one correspondence with the transition openings 1112. Specifically, there are three sliders 2212, each of different sizes; there are three transition openings 1112, each of which serves as a fool-proof positioning opening 1113, which can prompt the user to correctly align the transition openings 1112 with the sliders 2212. Thus, the starting point of each slider 2212's travel (i.e., the corresponding transition opening 1112) is uniquely determined, and the end point of each slider 2212's travel (i.e., the first limiting structure 31 provided on the chute 1111) is uniquely determined. The first conductive portion 13 and the second conductive portion 23 are configured so that conduction occurs when the slider 2212 slides to the end point of its travel in the chute 1111. This ensures that when the user directly plugs the heating base 2 into the power supply base 1, the user can align the first conductive portion 13 and the second conductive portion 23 and achieve conduction without prompting.

[0058] In a specific example, the plug-in section 221 is constructed as a cylinder, and the slider 2212 is an arc-shaped block protruding from the side surface of the cylinder; the installation cavity 11 is constructed as a cylindrical cavity, the transition opening 1112 is constructed as an arc-shaped opening recessed in the inner surface of the installation cavity 11, and the slide groove 1111 is an arc-shaped groove recessed in the inner surface of the installation cavity 11.

[0059] In a preferred embodiment, the plug-in section 221 is constructed as a cylinder, and the slider 2212 is an arc-shaped block protruding from the side surface of the cylinder. There are multiple sliders 2212, one of which is constructed as a positioning block 2213. The central angle corresponding to the positioning block 2213 is different from the central angles corresponding to the other sliders 2212, and the radius corresponding to the positioning block 2213 is the same as the radius corresponding to the other sliders 2212. In this way, the slider 2212 serving as the positioning block 2213 is dimensionally different from the other sliders 2212, and the chute 1111 can adopt the same groove depth and groove length, and the chute 1111 can be processed and manufactured uniformly, thereby reducing the difficulty of production and processing.

[0060] Example 3

[0061] like Figure 8As shown, this embodiment is basically the same as the first embodiment, except that: the heating seat 2 includes a heating seat shell 22 with one end open, a top cover 21 and a heating component 26, the top cover 21 is used to close the opening 222 of the heating seat shell 22, the heating component 26 is arranged in the accommodating cavity 25 enclosed by the top cover 21 and the heating seat shell 22 and is used to transfer heat to the top cover 21; at least a portion of the heating seat shell 22 forms an inserting section 221, and the edge of the top cover 21 extends in a direction away from the heating seat shell 22 to form a first vertical flange 211, the first vertical flange 211 is provided with a connecting portion 210 and a second folding portion 212, the extension direction of the second folding portion 212 is different from the extension direction of the first vertical flange 211 and is used to abut against the edge of the opening 222 of the heating seat shell 22. The heating seat 2 closes the opening 222 of the heating seat shell 22 through the top cover 21. The heating seat shell 22 and the top cover 21 can protect the heating component 26 and form a sealed and waterproof structure. The heating seat 2 can be directly cleaned to ensure the hygiene and safety of the milk warmer 100.

[0062] Furthermore, a first seal 41 is provided between the second folded portion 212 and the heating base housing 22. The plug-in section 221 has a through hole 224 for receiving the second conductive portion 23. A second seal 42 is provided between the second conductive portion 23 and the through hole 224. The provision of the first and second seals 41, 42 further enhances the sealing performance of the accommodating cavity 25, extending the service life of the milk warmer 100.

[0063] Furthermore, the heater housing 22 is provided with a boss fastening structure 223 protruding from its inner surface, and the second conductive portion 23 is fixed to the boss fastening structure 223 via a fastener 5. This means that the boss fastening structure 223 does not connect to the outside of the heater housing 22, thus reducing the number of through holes 224 in the heater housing 22 and further improving the sealing of the accommodating cavity 25.

[0064] The boss fastening structure 223 includes a boss and a threaded hole within the boss. The second conductive portion 23 includes a first circuit board 24 with a fastening hole. Fasteners 5 pass through the fastening hole and the boss fastening structure 223 to secure the first circuit board 24 to the heater housing 22. The second conductive portion 23 also includes multiple conductive probes, all of which are connected to the first circuit board 24.

[0065] Example 4

[0066] like Figure 8As shown, this embodiment is basically the same as the third embodiment, with the difference being that the side of the top cover 21 facing the accommodating cavity 25 is fixedly connected to the heating component mounting structure, the heating component 26 is mounted on the heating component mounting structure, and then the top cover 21 and the heating component 26 are assembled to the heating base housing 22. The heating component 26 is arranged close to the top cover 21, which can improve the heat transfer efficiency of the heating component 26.

[0067] like Figure 8 As shown, the heating assembly mounting structure further includes a pressing plate 213; the heating assembly 26 includes a heating plate 261 and a temperature probe 262; the pressing plate 213 is used to press the heating plate 261 and the temperature probe 262 against the top cover 21, and the temperature probe 262 can detect temperature information on the top cover 21. Thus, the pressing plate 213 makes the heating plate 261 and the temperature probe 262 adhere to the top cover 21, which can further improve the heat transfer efficiency.

[0068] like Figure 8 As shown, specifically, the heating plate 261 and the temperature probe 262 are spaced apart and arranged on the pressure plate 213; a second fastening hole is provided on the pressure plate 213, and the fastener 5 presses the heating plate 261 and the temperature probe 262 against the top cover 21 through the second fastening hole and the heating component mounting structure.

[0069] like Figure 8 As shown, the heating component 26 further includes a heat insulating pad 214 , which is arranged between the temperature sensing probe 262 and the heating plate 261 , and can improve the accuracy of temperature measurement by the temperature sensing probe 262 .

[0070] Specifically, the thermal insulation pad 214 includes a heating plate silicone pad and a temperature probe silicone sleeve. The heating plate silicone pad is positioned between the pressure plate 213 and the top cover 21 and defines a heating plate mounting slot for mounting the heating plate 261. One side of the heating plate mounting slot is open, and the thickness of the heating plate 261 is no less than the depth of the slot. The temperature probe silicone sleeve is positioned over the outer circumference of the temperature probe 262, with at least a portion of the temperature probe 262 extending out of the silicone sleeve and resting against the top cover 21.

[0071] like Figure 9 and Figure 10As shown, further, the power supply base 1 is provided with a switch 14, a temperature adjustment key and a control circuit board 15, and the control circuit board 15 is electrically connected to the switch 14, the first conductive part 13 and the temperature adjustment key. The power supply base 1 is also provided with a display component 16 electrically connected to the control circuit board 15, and the display component 16 is used to display the temperature information detected by the temperature sensor 262. The power supply base 1 is also provided with a battery 17 and a power socket 18, and the battery 17 and the power socket 18 are both electrically connected to the control circuit board 15. In other words, arranging the electric control component and the battery 17 on the power supply base 1 can further reduce the weight of the heating base 2 and improve the convenience of using the milk warmer 100.

[0072] Specifically, the heating seat 2 and the power supply seat 1 are in contact with each other through the first conductive part 13 and the second conductive part 23 to control the current on and off of the heating plate 261 and transmit the signal of the temperature sensor 262 to the control board for temperature control.

[0073] like Figure 9 and Figure 10 As shown, in some specific examples, the display component 16 includes a printed film, a light source and a light shield. The printed film is arranged at the end of the light shield, and the light source is arranged at the other end of the light shield away from the printed film and is electrically connected to the control circuit board 15.

[0074] An anti-skid pad is also provided at the bottom of the power supply stand 1 to improve the stability of the power supply stand 1.

[0075] like Figure 11 As shown, in some embodiments, the milk warmer 100 further includes a milk bottle 200, a dust cover 400, and a third sealing member 300. The connecting portion 210 can be selectively connected to the milk bottle 200 or the dust cover 400; the third sealing member 300 is used to seal the fitting between the bottle mouth of the milk bottle 200 and the connecting portion 210.
