Detailed Embodiments

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0031] Please refer to Figures 1-6 In the embodiment of the present utility model, a liquid heating device with high thermal conductivity includes a power supply base 1 and a liquid storage 2 connected thereto. The liquid storage 2 has a liquid storage cavity 3. One end of the liquid storage 2 cooperating with the power supply base 1 is provided with a heating part 4 corresponding to its liquid storage cavity 3. An assembly groove 5 is formed on the surface of the heating part 4. An isolation wall 6 is formed between the assembly groove 5 and the liquid storage cavity 3. A heating element 7 is arranged in the assembly groove 5, and the heating element 7 is closely attached to the isolation wall 6. Among them, the heating element 7 is electrically connected to the control module 22 of the power supply base 1.

[0032] In the technical solution of the present utility model, this liquid heating device is composed of two parts: a power supply base 1 and a liquid storage 2. The power supply base 1 and the liquid storage 2 can be fixedly connected or detachably connected. Among them, the split design not only facilitates use and operation but also is convenient for maintaining and replacing different components;

[0033] The power supply base 1 provides stable power supply for the entire device to ensure the smooth progress of the heating process. The liquid storage 2 part has a liquid storage cavity 3 for accommodating the liquid to be heated. One end of the liquid storage 2 cooperating with the power supply base 1 is provided with a heating part 4 corresponding to the liquid storage cavity 3. This heating part 4 is the key area for realizing efficient heating. Specifically, an assembly groove 5 is formed on the surface of the heating part 4. The design of the assembly groove 5 has multiple functions. On the one hand, it provides an installation position for the heating element 7, enabling the heating element 7 to be stably placed therein; on the other hand, the isolation wall formed between the assembly groove 5 and the liquid storage cavity 3 plays an important role during the heating process. The isolation wall can not only prevent the heating element 7 from directly contacting the liquid in the liquid storage cavity 3, avoiding safety risks such as electric leakage, but also control the heat transfer direction to a certain extent and improve the heat transfer efficiency;

[0034] Furthermore, placing the heating element 7 in the assembly groove 5 and making it closely attached to the isolation wall minimizes the heat loss during the heat transfer process. Because the close contact between the heating element 7 and the isolation wall enables heat to be quickly conducted to the liquid storage cavity 3. At the same time, the heating element 7 closely attached to the isolation wall can transfer heat to the liquid in the liquid storage cavity 3 more evenly, avoiding the occurrence of local overheating;

[0035] In summary, by placing the heating element 7 close to the isolation wall and the design of the assembly groove 5 makes the contact between the heating element 7 and the liquid storage chamber 3 closer, the heat conduction efficiency is greatly improved, and the heat can be quickly transferred to the liquid in the liquid storage chamber 3, shortening the heating time and reducing energy waste. At the same time, the isolation wall between the assembly groove 5 and the liquid storage chamber 3 plays a good isolation role, preventing the heating element 7 from directly contacting the liquid, reducing safety risks such as leakage, and improving the safety of the device. The design principle of this thermal conductive high-efficiency liquid heating device is suitable for heating various liquids, whether it is a milk warmer for infant feeding, or for heating coffee, tea, water and other liquids in scenes such as homes and offices, it can play a good effect. Its wide applicability provides users with more choices and convenience.

[0036] In the embodiment of the utility model, the bottom end of the heating part 4 is fixedly provided with a bottom cover 8 connected to the assembly groove 5, and at least one layer of thermal insulation 9 is also arranged in the assembly groove, and at least one layer of the thermal insulation 9 is located between the heating element 7 and the bottom cover 8.

[0037] At least one layer of heat insulating member 9 is arranged in the assembly groove and is located between the heating element 7 and the bottom cover 8. The main function of the heat insulating member 9 is to reduce the transfer of heat to the bottom cover 8, prevent heat loss, and improve thermal efficiency. The heat insulating member 9 can be made of materials with good heat insulating properties, such as asbestos, ceramic fiber, aerogel, etc. These materials can effectively block the conduction of heat and reduce heat loss. The number of layers of the heat insulating member 9 can be adjusted according to actual needs. Increasing the number of layers of the heat insulating member 9 can further improve the heat insulating effect.

[0038] A bottom cover 8 is fixedly provided at the bottom end of the heating part 4 and is connected to the assembly groove 5. The bottom cover 8 serves to close or substantially close the assembly groove 5. It fits tightly with the assembly groove 5 to ensure that the heating element 7 and the thermal insulation member 9 can be stably installed in the assembly groove 5 to prevent them from being displaced or falling off during use. If the bottom cover 8 is tightly closed, it can also play a certain protective role to prevent external factors from damaging the heating element 7 and the thermal insulation member 9. For example, it can prevent dust, moisture, etc. from entering the assembly groove 5 and affecting the performance and life of the heating element 7.

[0039] In the embodiment of the utility model, the heat insulating member 9 is arranged closely to the heating element 7 .

[0040] The thermal insulation member 9 is arranged close to the heating element 7, which makes full use of the space and enables the thermal insulation member 9 to exert its thermal insulation effect to the greatest extent. Since the thermal insulation member 9 is in direct contact with the heating element 7, it can block the transfer of heat in a specific direction at the source of heat generation. This close-fitting design can ensure that there is no gap between the thermal insulation member 9 and the heating element 7, avoiding heat from being conducted through the gap to the part that does not need heating, thereby achieving more precise thermal control.

[0041] In an embodiment of the present utility model, the heat insulation member 9 is bonded to the side of the heating element 7 away from the isolation wall 6;

[0042] Or, through the fixation of the bottom cover 8 and the heating part 4, the bottom cover 8 is abutted against the heat insulation member 9, and the heat insulation member 9 is closely attached to the side of the heating element 7 away from the isolation wall 6.

[0043] Bonding the heat insulation member 9 to the side of the heating element 7 away from the isolation wall 6, the adhesive force of the adhesive is used to firmly attach the heat insulation member 9 to the heating element 7. This method ensures that the heat insulation member 9 will not easily fall off or shift during the operation of the heating element 7, guaranteeing the stability of the heat insulation effect. Among them, the selection of the adhesive needs to consider its high temperature resistance, bonding strength, and adaptability to the materials of the heating element 7 and the heat insulation member 9, ensuring that the adhesive will not fail during the heating process and will not have an adverse effect on the performance of the heating element 7;

[0044] Through the fixation of the bottom cover 8 and the heating part 4, the bottom cover 8 will abut against the heat insulation member 9 during the installation process, so that the heat insulation member 9 is closely attached to the side of the heating element 7 away from the isolation wall 6. This design utilizes the installation pressure of the bottom cover 8 to achieve the close fitting of the heat insulation member 9. Among them, the fixation method of the bottom cover 8 and the heating part 4 can adopt screw connection, snap connection, etc., to ensure the firmness and stability of the connection. During the installation process, the pressure of the bottom cover 8 acts evenly on the heat insulation member 9, making it in close contact with the heating element 7; specifically, for example, threaded posts 20 are provided on the heating part 4, and connection holes 21 matching the threaded posts 20 are opened on the bottom cover 8, thereby realizing the fixation of the bottom cover 8 and the heating part 4.

[0045] In one embodiment, the heating element 7 is integrally connected to the heating part 4 by the insert molding process.

[0046] The heating element 7 can be a thick film heating element. The thick film heating element is an advanced heating element 7, which has the advantages of uniform heating, rapid temperature rise, high thermal efficiency, strong reliability, etc. It is usually formed by printing conductive paste on an insulating substrate to form a heating circuit, and then sintered at high temperature;

[0047] The insert molding process is a process of combining two different materials by injection molding, etc. In this design, the heating element 7 (thick film heating element) and the heating part 4 are connected by the insert molding process. First, the basic structure of the heating part 4 is manufactured, usually using materials with a certain strength and heat resistance. Then, through specific molds and processes, the thick film heating element is injection molded and wrapped at a specific position of the heating part 4 to make the two closely combined;

[0048] Through the overmolding process, the heating element 7 is integrally connected to the heating part 4, avoiding problems such as loosening and falling off that may occur in the traditional connection method. This integrated structure makes the entire liquid heating device more stable and reliable, capable of withstanding greater mechanical stress and thermal stress. Moreover, the heating element 7 can be tightly combined with the heating part 4, thereby effectively reducing the contact thermal resistance between the two, improving the heat transfer efficiency. The heat generated by the heating element 7 can be transferred to the heating part 4 more quickly and evenly, and then transferred to the liquid in the liquid storage cavity 3, achieving the effect of shortening the heating time, thereby realizing the high thermal conductivity performance of this liquid heating device.

[0049] In the embodiment of the present utility model, the assembly groove 5 includes a first slot 10 corresponding to the heating element 7 and a second slot 11 corresponding to the heat insulation member 9. Among them, a covering edge 12 acting on the heating element 7 is formed around the edge of the first slot 10.

[0050] It can be understood that the first slot 10 and the second slot 11 are connected.

[0051] In one embodiment, the assembly groove 5 is clearly divided into a first slot 10 corresponding to the heating element 7 and a second slot 11 corresponding to the heat insulation member 9. For the first slot 10, considering the overmolding process with the heating element 7, a structure with good material compatibility with the heating element 7 and capable of withstanding temperature and pressure changes during the overmolding process needs to be selected. Taking the warmer as an example, the liquid storage 2, that is, the cup body, is made of PPSU (polyphenylsulfone) material. This material has the advantages of high temperature resistance, chemical corrosion resistance, high strength, etc., and is suitable for storing liquids such as milk. That is, the size and shape of the first slot 10 are designed according to the heating element 7 (thick film heating element) so as to achieve a tight combination of the two through the overmolding process, thus distinguishing the first slot 10 and the second slot 11.

[0052] In one embodiment, when both the heating element 7 and the heating member are assembly bodies, the clearly divided first slot 10 and second slot 11 enable the heating element 7 and the heat insulation member 9 to be accurately installed in the predetermined positions, improving the installation accuracy. This precise installation helps to ensure the tight contact between the heating element 7 and the isolation wall and the heat insulation member 9, thereby improving the heat transfer efficiency and heat insulation effect; (at this time, under the abutting action of the bottom cover 8 and the heat insulation member 9, the heating element 7 can be closely attached to the isolation wall 6); or, corresponding to this assembly body method, the assembly groove 5 may not distinguish the first slot 10 and the second slot 11, and can be reasonably designed according to the actual situation.

[0053] In the embodiment of the present utility model, a first through hole 13 is formed on the central surface of the heating element 7, and a flange portion 14 corresponding to the first through hole 13 is formed on one side of the isolation wall 6 corresponding to the assembly groove 5.

[0054] A first through hole 13 is formed in the central surface of the heating element 7, and this first through hole 13 can serve multiple functions: On the one hand, it can be part of the heat dissipation channel. During the heating process, it allows a part of the heat to be dissipated through the through hole, avoiding excessive local temperature of the heating element 7, thereby improving the service life and stability of the heating element 7; On the other hand, the existence of the first through hole 13 can also reduce the weight of the heating element 7, reducing the weight and cost of the entire device; Additionally, the first through hole 13 can be used as the glue inlet when the storage liquid 2 is overmolded with the heating element 7. During the overmolding process, the molten storage liquid 2 material (such as the ppus material of the baby warmer cup body) can be injected through this first through hole 13 into the space between the heating element 7 and the heating part 4 of the storage liquid 2. This can ensure that the material is evenly distributed around the heating element 7, achieving a firm integrated connection. Moreover, the position of the first through hole 13 on the central surface of the heating element 7 is conducive to the uniform flow and filling of the material, avoiding local lack of glue or unevenness;

[0055] On one side of the partition wall 6 corresponding to the assembly groove 5, a flange portion 14 corresponding to the first through hole 13 is formed. The flange portion 14 and the first through hole 13 cooperate with each other, playing the role of enhancing the structural stability and improving the heat transfer efficiency. The flange portion 14 can be inserted into the first through hole 13, increasing the contact area between the heating element 7 and the partition wall 6, thereby improving the heat transfer efficiency. At the same time, the flange portion 14 can also play the role of positioning and fixing the heating element 7, preventing the heating element 7 from moving or being misaligned in the assembly groove 5; Furthermore, the cooperation between the flange portion 14 and the first through hole 13 also plays a certain role during the glue injection process. The flange portion 14 can guide the flow direction of the molten material, ensuring that the material is accurately filled into the required position. At the same time, the flange portion 14 can also enhance the strength and stability of the connection part after the glue injection.

[0056] In the embodiment of the present utility model, a second through hole 15 is formed along the surface of the flange portion 14, and a temperature sensor 16 is arranged at the position of the second through hole 15;

[0057] Among them, the head of the temperature sensor 16 passes through the second through hole 15 and extends into the liquid storage cavity 3 to form a temperature sensing end 17, and the tail of the temperature sensor 16 is electrically connected to the control module 22 of the power supply base 1 through a wire.

[0058] A second through-hole 15 is formed on the surface of the flange portion 14, providing an installation position for the temperature sensor 16. The flange portion 14 itself corresponds to the first through-hole 13 of the heating element 7 and is located close to the liquid storage cavity 3. This position is conducive to the temperature sensor 16 accurately sensing the temperature of the liquid in the liquid storage cavity 3. The size and shape of the second through-hole 15 are designed according to the temperature sensor 16 to ensure that the temperature sensor 16 can be stably installed therein without affecting the structural stability and heat transfer efficiency between the flange portion 14 and the first through-hole 13.

[0059] The head of the temperature sensor 16 passes through the second through-hole 15 and extends into the liquid storage cavity 3 to form a temperature sensing end 17. This temperature sensing end 17 is in direct contact with the liquid and can quickly and accurately sense the temperature change of the liquid, which is very important for a liquid heating device, especially for devices such as a milk warmer that require precise temperature control, ensuring that liquids such as milk are heated to an appropriate temperature and guaranteeing the feeding safety of infants. The tail of the temperature sensor 16 is electrically connected to the control module 22 of the power supply base 1 through a wire to transmit the sensed temperature signal to the control module 22.

[0060] In the embodiment of the present utility model, an I-shaped connecting portion 18 is extended and provided along the side of the heating element 7 away from the isolation wall 6, and a connecting column 19 is provided on the power supply base 1 and is in locking butt joint with the I-shaped connecting portion 18.

[0061] The I-shaped connecting portion 18 is extended and provided along the side of the heating element 7 away from the isolation wall 6. The I-shaped connecting portion 18 has a specific shape and size. Its transverse part can provide a larger contact area to enhance the connection stability. The longitudinal part plays a role in connection and positioning. This I-shaped design can increase the strength and rigidity of the connecting portion, enabling it to withstand a certain amount of tensile force, pressure, and torque.

[0062] The power supply base 1 is provided with a connecting column 19 that is in locking butt joint with the I-shaped connecting portion 18. The shape and size of the connecting column 19 match those of the I-shaped connecting portion 18 to achieve a tight connection. When the I-shaped connecting portion 18 is butt-jointed with the connecting column 19, the two can be fixed together by screwing (for example, the I-shaped connecting portion 18 has internal threads).

[0063] Since the heating element 7 is closely combined with the heating part 4 of the liquid storage 2 (i.e., integrally connected), when the I-shaped connecting part 18 is locked and connected to the connecting column 19, the connection between the power supply base 1 and the liquid storage 2 is actually achieved. This connection method enables electric power to be stably transmitted from the power supply base 1 to the heating element 7, thereby providing energy for heating the liquid in the liquid storage 2, and at the same time simplifying the assembly of the liquid storage 2 and the power supply base 1. Moreover, the I-shaped connecting part 18 can also serve as a positioning structure when the heating element 7 and the liquid storage 2 are integrally injection-molded, that is, cooperate with the corresponding mold to prevent the heating element 7 from being displaced.

[0064] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
