[0035] To facilitate understanding of the heated thermos provided in this application embodiment, its application scenario will be described first. The heated thermos provided in this application embodiment falls under the field of daily necessities and can be specifically applied to containing liquids, maintaining liquid temperature, and heating liquids.

[0036] To address the problem of beverages cooling down, heated insulated cups have emerged on the market. These products typically integrate a heating element at the bottom or side of the cup and are equipped with a power source to heat or keep the beverage inside warm.

[0037] However, the insulation layer of existing heated thermos cups often fails to effectively isolate the heating components and power modules at the bottom, resulting in significant heat loss from the heating components, reduced heating efficiency, and decreased heat retention performance of the heated thermos cup.

[0038] Based on this, this application provides a heated thermos cup, aiming to improve the heating efficiency and heat preservation performance of the heated thermos cup. The heated thermos cup provided in this application will be described in detail below with reference to the accompanying drawings.

[0039] Please refer to the above. Figure 1 and Figure 2 , Figure 1 This is one of the exemplary overall schematic diagrams of a heated thermos cup in this application. Figure 2 This is a second exemplary overall schematic diagram of a heated thermos cup according to this application. The thermos cup provided in this embodiment includes an outer wall panel 2 and an inner wall panel 1. The inner wall panel 1 is nested inside the outer wall panel 2, and a vacuum cavity 9 is formed between the outer wall panel 2 and the inner wall panel 1. This vacuum cavity 9 is the heat preservation layer of the heated thermos cup.

[0040] As a concrete example, the outer wall panel 2 can be formed into a cylindrical structure, and the inner wall panel 1, inside the outer wall panel 2, can also form a cylindrical structure. There is a certain gap between the inner wall panel 1 and the outer wall panel 2, thus forming a cavity between them. The edges of the inner wall panel 1 and the outer wall panel 2 are fixedly connected, sealing the cavity between them. Then, the cavity between the inner wall panel 1 and the outer wall panel 2 is evacuated, forming a vacuum cavity 9 between them. The vacuum cavity 9 can block heat transfer, thereby achieving the purpose of heat preservation.

[0041] When the inner wall panel 1 forms a cylindrical structure inside the outer wall panel 2, it specifically forms a mutually isolated receiving cavity 3 and a heating cavity 4. The receiving cavity 3 is the main receiving part of the heated thermos cup, and it can be used to hold liquids, etc. The heating cavity 4 is equipped with a heating element 5, which is used to heat the receiving cavity 3. Here, the receiving cavity 3 and the heating cavity 4 are completely isolated.

[0042] The inner wall plate 1 that isolates the receiving cavity 3 from the heating cavity 4 can be made of a thermally conductive material. The heating component 5, which is installed in the heating cavity 4, can conduct heat to the receiving cavity 3 through this inner wall plate 1, thereby heating the receiving cavity 3. In this way, when the receiving cavity 3 contains liquid, the heating component 5 can heat the liquid in the receiving cavity 3.

[0043] When forming the vacuum chamber 9, the vacuum chamber 9 at least partially encloses the side of the heating component 5 that is away from the receiving cavity 3. This means that the vacuum chamber 9 can either completely enclose the side of the heating component 5 that is away from the receiving cavity 3, or it can only enclose a portion of that side.

[0044] It is worth noting that, in the specific arrangement of the heating component 5, the heating component 5 can be fitted against the bottom wall or side wall of the receiving cavity 3, thereby enabling the heating component 5 to heat the liquid contained in the receiving cavity 3. The side of the heating component 5 between the side close to the receiving cavity 3 and the side away from the receiving cavity 3 constitutes the side surface of the heating component 5. Optionally, when the vacuum cavity 9 is used to wrap the side of the heating component 5 away from the receiving cavity 3, the vacuum cavity 9 can wrap the entire side surface of the heating component 5, then move around to the side of the heating component 5 away from the receiving cavity 3, and wrap at least a portion of the side of the heating component 5 away from the receiving cavity 3.

[0045] As a concrete example, such as Figure 1The heated thermos cup shown has a receiving cavity 3 with an opening. A heating cavity 4 is located on the side of the receiving cavity 3 away from the opening. An inner wall plate 1 forms a first bottom wall 112 on the side of the receiving cavity 3 away from the opening, separating the receiving cavity 3 from the heating cavity 4. A heating component 5 heats the receiving cavity 3 through the first bottom wall 112. The inner wall plate 1 also forms a second bottom wall 122 on the side of the heating cavity 4 away from the receiving cavity 3. The second bottom wall 122 covers the side of the heating component 5 away from the receiving cavity 3 almost completely, leaving only the necessary lead wire channel. An outer wall plate 2 completely covers the side of the inner wall plate 1 away from the receiving cavity 3 and the heating cavity 4, and vacuum cavities 9 are formed between the outer wall plate 2 and the receiving cavity 3, and between the outer wall plate 2 and the heating cavity 4. These vacuum cavities 9 also cover the side of the heating component 5 away from the receiving cavity 3. These vacuum cavities 9 can prevent heat exchange between the receiving cavity 3 and the outside environment, and can also prevent heat exchange between the heating cavity 4 and the outside environment.

[0046] In the heated thermos cup provided in this application embodiment, when the heating component 5 heats the receiving cavity 3, the vacuum cavity 9 at least partially covers the side of the heating component 5 away from the receiving cavity 3. The covering of the vacuum cavity 9 can reduce the heat loss of the heating component 5 from the side of the heating component 5 away from the receiving cavity 3, thereby allowing the heat of the heating component 5 to be supplied to the receiving cavity 3 more concentratedly, thus improving the heating efficiency of the heated thermos cup.

[0047] In addition, when the heating component 5 is not working, if the temperature of the heating chamber 4 is lower than that of the receiving chamber 3, the heat of the liquid in the receiving chamber 3 can also be lost to the heating chamber 4. Therefore, in this application, by setting the vacuum chamber 9 to at least partially cover the side of the heating component 5 away from the receiving chamber 3, the heat loss of the heating chamber 4 can be reduced, thereby reducing the heat loss of the receiving chamber 3, which improves the heat preservation performance of the heated thermos cup.

[0048] As an optional implementation, the inner wall panel 1 includes a first inner wall 11 and a second inner wall 12. The first inner wall 11 forms a receiving cavity 3, and the second inner wall 12 is fixedly connected to the first inner wall 11 and forms a heating cavity 4.

[0049] Specifically, the first inner wall 11 includes an integrally formed first side wall 111 and a first bottom wall 112, wherein the first side wall 111 forms a cylindrical structure; the first bottom wall 112 is located on the side of the receiving cavity 3 away from the opening and seals the cylindrical structure formed by the first side wall 111, and together with the first side wall 111, forms the receiving cavity 3.

[0050] The second inner wall 12 includes an integrally formed second side wall 121 and a second bottom wall 122. The second side wall 121 also forms a cylindrical structure, and the end of the second side wall 121 near the receiving cavity 3 is fixedly connected to the first inner wall 11. The second bottom wall 122 is located at the end of the second side wall 121 away from the receiving cavity 3. Thus, the second bottom wall 122 and the second side wall 121 together form a heating cavity 4 on the side of the first bottom wall 112 away from the receiving cavity 3.

[0051] The outer wall panel 2 covers the outer sides of the first side wall 111, the second side wall 121, and the second bottom wall 122, thereby completely covering the inner wall panel 1 and forming a vacuum cavity 9 between the outer wall panel 2 and the inner wall panel 1. It is worth noting that when the second inner wall 12 is fixedly connected to the first inner wall 11, the joint between the second inner wall 12 and the first inner wall 11 should be sealed to ensure the airtightness of the vacuum cavity 9.

[0052] By using the first inner wall 11 and the second inner wall 12 to form the inner wall panel 1, the molding difficulty of the inner wall panel 1 can be reduced; and when assembling the heating and insulation cup, the heating component 5 can be placed after the heating chamber 4 and then the second inner wall 12 can be fixedly connected to the first inner wall 11, which reduces the assembly difficulty of the heating component 5.

[0053] The heating component 5 in this embodiment can be powered by an external DC or AC power source, or it can be powered directly by a built-in battery in the heating and insulation cup.

[0054] As an optional implementation, the heated thermos cup provided in this application embodiment also includes a battery assembly 6, which is disposed outside the vacuum chamber 9, that is, outside the heating chamber 4. On the side of the heating assembly 5 away from the receiving cavity 3, the second inner wall 12 is fixedly connected to the outer wall plate 2 and forms a lead wire hole 7. The battery assembly 6 is electrically connected to the heating assembly 5 through a power supply line passing through the lead wire hole 7. Specifically, at the edge of the lead wire hole 7, the second inner wall 12 is fixedly connected to the outer wall plate 2, and the gap of the fixed connection is sealed to ensure the airtightness of the vacuum chamber 9. By providing the lead wire hole 7, the heat exchange channel area between the heating chamber 4 and the external environment of the vacuum chamber 9 can be reduced, thereby reducing heat loss in the heating chamber 4 and further improving the heating efficiency and heat preservation performance of the heated thermos cup.

[0055] In addition, placing the battery assembly 6 outside the vacuum chamber 9 can reduce the heat transfer from the heating chamber 4 to the battery assembly 6, thereby reducing the temperature rise of the battery assembly 6 and improving its safety and lifespan.

[0056] Optionally, the heated thermos also includes a battery compartment wall, which is fixedly connected to the outer wall panel 2 and forms a battery compartment, where the battery assembly 6 is housed. By using a battery compartment wall to form the battery compartment, the battery can be protected, and the appearance of the instant heated thermos can be improved.

[0057] As an optional implementation, the battery assembly 6 includes a power supply board 61 and a battery 62. The power supply board 61 is fixedly connected to the outer wall panel 2 and seals the lead hole 7; the battery 62 is electrically connected to the power supply board 61, and the power supply board 61 is electrically connected to the power supply line. Specifically, the power supply board 61 can be a PCB circuit board. The battery 62 is electrically connected to the power supply board 61 via wires, and the power supply line is also connected to the power supply board 61. The wires and the power supply line are then connected through the power supply board 61, allowing the battery 62 to supply power to the heating assembly 5 through the power supply board 61.

[0058] By setting the power supply board 61 to block the lead hole 7, the heat exchange between the inside of the heating chamber 4 and the outside of the vacuum chamber 9 can be further blocked, thereby further reducing the heat loss of the heating chamber 4 and further improving the heating efficiency and heat preservation performance of the thermos cup.

[0059] As an optional implementation, the battery assembly 6 also includes a main control circuit board 64 and a U-shaped bracket 63; the U-shaped bracket 63 is fixed on the side of the outer wall panel 2 away from the vacuum chamber 9, and the opening direction of the U-shaped bracket 63 is away from the outer wall panel 2; the battery 62 is fixed inside the U-shaped bracket 63, and the main control circuit board 64 is fixed on the side wall of the U-shaped bracket 63; the battery 62 is electrically connected to the main control circuit board 64, and the main control circuit board 64 is electrically connected to the power supply board 61.

[0060] Optionally, the main control circuit board 64 may include components such as resistors and capacitors required to supply power to the heating assembly 5; in some optional embodiments, the main control circuit board 64 may also be provided with related components for controlling the start and stop of the heating assembly 5. The U-shaped bracket 63 may be fixedly connected to the outer wall panel 2 by means of threaded connectors, adhesive bonding, welding, etc., and the battery 62 may also be fixedly connected to the U-shaped bracket 63 by means of threaded connectors, adhesive bonding, welding, etc.

[0061] The battery 62 is electrically connected to the main control circuit board 64, which in turn is electrically connected to the power supply board 61. Thus, the battery 62 can supply power to the heating element 5 sequentially through the main control circuit board 64 and the power supply board 61. Placing both the battery 62 and the main control circuit board 64 outside the vacuum chamber 9 reduces the amount of heat absorbed by the battery 62 and the main control circuit board 64 from the heating element 5, thus controlling their temperature rise and protecting them. Furthermore, fixing the battery 62 and the main control circuit board 64 together using the U-shaped bracket 63 makes the battery assembly 6 more compact, saving internal space in the heated thermos cup.

[0062] Optionally, when fixing the main control circuit board 64 to the U-shaped bracket 63, the main control circuit board 64 can be fixed to the side wall of the U-shaped bracket 63, with the main control circuit board 64 and the battery 62 positioned on opposite sides of the side wall of the U-shaped bracket 63, that is, the main control circuit board 64 is fixed to the outside of the U-shaped bracket 63. By fixing the main control circuit board 64 to the side of the U-shaped bracket 63 away from the battery 62, the heat absorbed by the main control circuit board 64 during the charging and discharging of the battery 62 can be reduced, thereby reducing the risk of the main control circuit board 64 being damaged due to high temperature.

[0063] Please refer to the above. Figure 3 , Figure 3 This is a schematic diagram of the heating assembly in an embodiment of this application. As an optional implementation, when specifically setting the heating assembly 5, the heating assembly 5 includes a heating plate 51 and a cooling needle 52. The heating plate 51 is used to heat the receiving cavity 3, while the cooling needle 52 serves as a power supply line electrically connecting the heating plate 51 and the power supply board 61. Specifically, the heating plate 51 and the cooling needle 52 are electrically connected and used to heat the receiving cavity 3; one end of the cooling needle 52 is connected to the heating plate 51, and the other end of the cooling needle 52 passes through the power supply board 61 and is exposed on the side of the power supply board 61 away from the heating cavity 4. The exposed end of the cooling needle 52 on the power supply board 61 away from the heating cavity 4 is electrically connected to the power supply board 61. Specifically, the cooling needle 52 can be welded to the power supply board 61 to achieve electrical connection with the power supply board 61.

[0064] The cold needle 52 is made of a conductive metallic material and can also be used to transfer heat. By directly connecting the heating plate 51 to the power supply board 61 with the cold needle 52, energy loss caused by additional wires can be reduced. In addition, the cold needle 52 can reduce the risk of local overheating of the heating plate 51 by conducting heat at the connection point between the heating plate 51 and the cold needle 52. Furthermore, by extending the cold needle 52 to the side of the power supply board 61 away from the heating cavity 4, the length of the cold needle 52 is increased, thereby reducing the temperature at the end of the cold needle 52 away from the heating plate 51. This reduces the risk of high-temperature damage to the power supply board 61 and minimizes heat loss outside the heating cavity 4.

[0065] As an optional implementation, the heated thermos cup also includes a temperature sensor 8, which is fixed to the heating chamber 4 and used to detect the temperature of the containing chamber 3. The lead wire of the temperature sensor 8 is connected to the power supply board 61, and the temperature signal is transmitted to the main control circuit board 64 through the power supply board 61. By setting the temperature sensor 8, the temperature of the containing chamber 3 can be sensed, and the start and stop of the heater can be controlled according to the temperature information, thereby improving the intelligence of the heated thermos cup. In addition, the temperature signal of the temperature sensor 8 is transmitted to the main control circuit board 64 through the power supply board 61, so that the temperature sensor 8 and the heating component 5 can be assembled together in the same module, improving the modularity of the heated thermos cup and thus improving the assembly efficiency of the temperature sensor 8.

[0066] Optionally, when specifically setting the temperature sensor 8, a sensor support frame can be provided to fix the temperature sensor 8. Specifically, one end of the sensor support frame passes through the lead hole 7 and is fixedly connected to the power supply board 61 or the inner wall plate 1, and the other end of the sensor support frame supports the temperature sensor 8 and makes the temperature sensor 8 fit against the first bottom wall 112.

[0067] As an optional implementation, when specifically setting the outer wall panel 2, the outer wall panel 2 includes an annular sidewall and a bottom wall fixedly connected to the annular sidewall, and the bottom wall is provided with a protruding structure 221. For ease of description, the annular sidewall of the outer wall panel 2 is named the third sidewall 21, and the bottom wall of the outer wall panel 2 is named the third bottom wall 22. The third sidewall 21 is arranged in an annular shape and forms a cylinder, and the inner wall panel 1 is disposed within the cylindrical space enclosed by the third sidewall 21, while the third bottom wall 22 blocks the side of the cylindrical space enclosed by the third sidewall 21 that is away from the opening of the receiving cavity 3. The protruding structure 221 provided on the third bottom wall 22 can be formed by bending the third bottom wall 22 itself toward the side away from the second bottom wall 122, or the protruding structure 221 of the third bottom wall 22 can be formed by bending a plate fixed to the side of the third bottom wall 22 away from the second bottom wall 122.

[0068] It is worth noting that when fixing the third side wall 21 and the third bottom wall 22, the connection gap between the third side wall 21 and the third bottom wall 22 needs to be sealed to ensure the airtightness of the vacuum chamber 9.

[0069] This design allows the annular sidewall and bottom wall of the outer wall panel 2 to be manufactured separately, and also facilitates the installation of the protruding structure 221 on the bottom wall. This simplifies the manufacturing process of the outer wall panel 2 and improves the production efficiency of the heated thermos cup. In addition, by installing the protruding structure 221 on the bottom wall, the structural strength of the bottom wall can be strengthened, reducing the risk of bottom wall deformation during vacuuming of the vacuum chamber 9.

[0070] As an optional implementation, the protrusion structure 221 is an annular protrusion. Specifically, the third bottom wall 22 has a shape that matches the end face of the cylindrical structure formed by the third side wall 21, and the annular protrusion is also arranged around the edge of the third bottom wall 22.

[0071] As described above, the third bottom wall 22 is fixedly connected to the third side wall 21 to seal one end of the cylindrical structure formed by the third side wall 21. Therefore, during vacuuming of the vacuum chamber 9, the third side wall 21 provides support to the edge of the third bottom wall 22 to prevent deformation under atmospheric pressure. However, along the edge of the third bottom wall 22 towards its center, as the lever arm gradually increases, the supporting effect of the third side wall 21 on the third bottom wall 22 gradually decreases, and the risk of deformation of the third bottom wall 22 gradually increases. By setting the annular protrusion structure 221, the structural stability of the third bottom wall 22 can be uniformly strengthened along the annular area, thereby further reducing the risk of deformation of the third bottom wall 22.

[0072] Optionally, when the inner wall panel 1 includes a first inner wall 11 and a second inner wall 12, and the second inner wall 12 is fixedly connected to the outer wall panel 2 to form a lead hole 7, the lead hole 7 is located within the space enclosed by the annular protrusion, that is, the annular protrusion surrounds the lead hole 7. At the lead hole 7, the second inner wall 12 is fixedly connected to the outer wall panel 2, that is, the second bottom wall 122 is fixedly connected to the third bottom wall 22. At this time, the second bottom wall 122 can also support the third bottom wall 22 to resist atmospheric pressure during vacuuming operations. The weak structural area of ​​the third bottom wall 22 is located between the lead hole 7 and the edge of the third bottom wall 22, and the annular protrusion surrounds the lead hole 7, precisely reinforcing the weak structural area of ​​the third bottom wall 22, thereby further improving the structural stability of the third bottom wall 22.

[0073] Optionally, when the heated thermos includes a battery assembly 6, and the battery assembly 6 includes a power supply board 61, the power supply board 61 is also located within the space enclosed by the annular protrusion. This arrangement allows the power supply board 61 to be accommodated within the space enclosed by the annular protrusion, improving the structural compactness of the heated thermos and saving internal space.

[0074] Please refer to the above. Figure 4 , Figure 4This is a schematic diagram of the connection between the U-shaped bracket and the bottom wall in an embodiment of this application. As an optional implementation, when the heating and insulation cup includes a battery assembly 6 and the battery assembly 6 includes a U-shaped bracket 63, the U-shaped bracket 63 is connected to the bottom wall of the outer wall panel 2 through a support column 631, and the support column 631 is located within the space enclosed by the annular protrusion. As a specific example, the support column 631 is specifically disposed between the annular protrusion and the lead hole 7. The support column 631 is fixed to the side of the bottom wall of the outer wall panel 2 away from the vacuum cavity 9 by means of bonding, welding, etc., that is, the support column 631 is fixed to the side of the third bottom wall 22 away from the second bottom wall 122. A stud or screw passes through the U-shaped bracket 63 and is threadedly connected to the support column 631, thereby fixing the U-shaped bracket 63 and the support column 631 together.

[0075] By setting the support column 631 to fix the U-shaped bracket 63 to the outer wall panel 2, it has the advantages of simple and quick assembly while ensuring connection strength; and by setting the support column 631 in the space enclosed by the annular protrusion, the space occupied by the support column 631 in the direction of the sequential arrangement of the battery assembly 6, the heating chamber 4 and the receiving chamber 3 can also be reduced, saving the internal space of the heating and insulation cup.
