[0052] Embodiments of the present utility model are described below with reference to the accompanying drawings.

[0053] An embodiment of the present utility model relates to a container 100. As Figure 1 、 Figure 2 、 Figure 4 and Figure 9 shown, the container 100 includes: a box body 1, a fixing seat 2, a heating element 3, and an electrical connector 4. A through hole is formed in the box body 1, and the fixing seat 2 is arranged in the through hole. The heating element 3 is arranged inside the box body 1, the electrical connector 4 is electrically connected to the heating element 3, and one end of the electrical connector 4 away from the heating element 3 is configured to be insertable and positioned in the fixing seat 2.

[0054] Since the heating element 3 is arranged inside the box body 1, when the inner lining bag is placed inside the box body 1, it can contact the heating element 3 and be heated, effectively improving the heat conversion rate and thus enhancing the heating efficiency, and greatly improving the operation convenience. Moreover, the electrical connector 4 can be inserted into the fixing seat 2, enabling the electrical connector 4 to be positioned and an external electrical connection line to be connected to the electrical connector 4. The electrical connector 4 is also electrically connected to the heating element 3 to achieve power supply and other controls for the heating element 3. Furthermore, the heating element 3 and the electrical connector 4 can be more reasonably installed in the box body 1.

[0055] As Figure 12 shown, the electrical connection end of the heating element 3 has a magnet 31, and a molded part 32 is arranged on the magnet 31 to cover the magnet 31. One end of the electrical connector 4 connected to the heating element 3 has a galvanized round iron 43, and the galvanized round iron 43 will attract and engage with the magnet 31. When assembled in place, the electrical connector 4 and the heating element 3 are in electrical contact, realizing the electrical connection between the electrical connector 4 and the heating element 3.

[0056] Furthermore, as Figure 1 and Figure 2 shown, the fixing seat 2 is detachably connected to the box body 1 or is an integral part of the box body 1. When the fixing seat 2 is detachably connected to the box body 1, the fixing seat 2 is provided with a rib 27 that can be stuck in the through hole. The fixing seat 2 and the box body 1 can also be an integral part and cannot be disassembled.

[0057] Furthermore, as Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10As shown, the fixed seat 2 has a mounting hole 20 into which one end of the electrical connector 4 is inserted. The upper wall surface of the mounting hole 20 has a mounting through surface portion 24 and a mounting fixing surface portion 25 that are connected in the direction from the inside of the container 100 to the outside of the container 100. The electrical connector 4 is a plug, and the end of the electrical connector 4 away from the heating element 3 is a wiring end, and the wiring end has a top surface of the end that cooperates with the upper wall surface of the mounting hole 20 and a bottom surface of the end that faces away from the top surface of the end. The top surface of the end is used to be inserted into the mounting hole 20 along the mounting through surface portion 24 and the mounting fixing surface portion 25, and is used to abut and position against the mounting fixing surface portion 25.

[0058] In addition, the upper wall surface of the mounting hole 20 further has a mounting positioning surface portion 26 connected to the mounting fixing surface portion 25. The top surface of the end is used to be inserted into the mounting hole 20 along the mounting through surface portion 24, the mounting fixing surface portion 25, and the mounting positioning surface portion 26, and is used to abut and position against the mounting fixing surface portion 25 and the mounting positioning surface portion 26.

[0059] Furthermore, as Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 shown, the mounting through surface portion 24 is a horizontal plane, and the mounting fixing surface portion 25 is an inclined plane that extends upward in the direction from the mounting through surface portion 24 to the mounting positioning surface portion 26. The top surface of the end has a top inclined surface portion 411 of the end with the same slope as the mounting fixing surface portion 25. When the wiring end is installed in the fixed seat 2, the top inclined surface portion 411 of the end abuts against the mounting fixing surface portion 25.

[0060] In addition, the mounting positioning surface portion 26 is a horizontal plane. The top surface of the end further has an end positioning surface portion 412 connected to the top inclined surface portion 411 of the end. When the wiring end is installed in the fixed seat 2, the top inclined surface portion 411 of the end abuts against the mounting fixing surface portion 25, and the end positioning surface portion 412 abuts and positions against the mounting positioning surface portion 26. Understandably, the mounting positioning surface portion 26 can also be inclined.

[0061] Furthermore, as Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 shown, the bottom surface of the end has an end bottom inclined surface portion 413 that extends upward in the direction away from the heating element 3, and the end bottom inclined surface portion 413 has the same slope as the top inclined surface portion 411 of the end. When the wiring end is inserted into the mounting hole 20 from the side facing the inside of the container 100 into the mounting hole 20, the top inclined surface portion 411 of the end moves along the mounting through surface portion 24, and the end bottom inclined surface portion 413 moves along the lower wall surface of the mounting hole 20.

[0062] Specifically, as shown in Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , when installing the heating element 3 and the electrical connection member 4, place the heating element 3 into the box body 1. First, lift one side of the heating element 3 to form a certain angle between the heating element 3 and the bottom of the container 100, and then push the heating element 3 so that the electrical connection member 4 is inserted into the electrical connection end of the heating element 3. Place the heating element 3 into the box body 1, and move the end of the electrical connection member 4 away from the heating element 3 to the mounting hole 20 of the fixing seat 2. During the process of inserting the electrical connection member 4 into the fixing seat 2, the heating element 3 and the electrical connection member 4 tilt together. The bottom inclined surface 413 of the end moves along the bottom surface of the box body 1 towards the mounting hole 20, and the bottom inclined surface 413 gradually moves to contact the lower wall surface of the mounting hole 20. The top inclined surface 411 of the end moves along the passing surface 24 of the mounting, and moves until the connection terminal is inserted into the mounting hole 20. Push the heating element 3 into place, level the heating element 3, the top inclined surface 411 of the end abuts against the mounting and fixing surface 25, the end positioning surface 412 abuts against the mounting and positioning surface 26, and the bottom surface of the connection terminal abuts against the lower wall surface of the mounting hole 20. At this time, both the heating element 3 and the electrical connection member 4 are horizontally placed, realizing the insertion and positioning of the electrical connection member 4 into the fixing seat 2, and it is not easy to shift from the fixing seat 2, which is convenient for the subsequent external connection wire 7 to be connected to the connection terminal. When it is necessary to remove the heating element 3 from the box body 1, the method is similar to that of installing the heating element 3 into the box body 1. After the heating element 3 slides a certain distance along the bottom surface of the box body 1, lift the heating element 3 upward to form a certain angle between the heating element 3 and the bottom surface of the box body 1, and continue to pull the heating element 3 to make the electrical connection member 4 slide along the fixing seat 2, realizing the removal of the heating element 3 and the electrical connection member 4 from the box body 1.

[0063] Furthermore, as shown in Figure 2 , Figure 3 , the fixing seat 2 includes: a seat body 21 and a flip cover 22 hinged to the seat body 21. The flip cover 22 is located outside the box body 1 and is used to turn outwards to open or cover the mounting hole 20. The flip cover 22 has a panel 221 and an outer frame 222 arranged around the panel 221. The outer frame 222 is used to be embedded in the mounting hole 20 when the panel 221 covers the mounting hole 20, and at least part of the end of the electrical connection member 4 away from the heating element 3 is inserted into the area formed by the surrounding of the outer frame 222.

[0064] In addition, as shown in Figure 2 , Figure 3As shown, the seat body 21 has an abutting surface 211 facing outside the container 100, and a sealing member 23 is provided in a ring shape on the side of the outer frame 222 facing the seat body 21. When the flip cover 22 covers the mounting hole 20, the outer frame 222 abuts against the abutting surface 211 in a sealed manner. The flip cover 22 and the seat body 21 are hinged together by an elastic member 28, and the elastic member 28 applies a torsional force to the flip cover 22 towards covering the mounting hole 20. The elastic member 28 can be a torsion spring. The torsion spring connects the seat body 21 and the flip cover 22 through a connecting shaft 29. Without other external forces, the torsion spring abuts against and turns over the flip cover 22 to seal the mounting hole 20.

[0065] Specifically, as Figure 1 、 Figure 9 shown, the container 100 includes: a base 11 and two pairs of opposite side plates 12. The two pairs of opposite side plates 12 are respectively foldably connected to the base 11; the base 11 has a base body 111 and two pairs of opposite extension plates 112 extending upward from the base body 111, and through holes are provided in the extension plates 112. The heating element 3 is laid in the base 11, so that when the side plates 12 are folded onto the base 11, it is not necessary to remove the heating element 3, and the folding of the box body 1 will not be affected.

[0066] Furthermore, the container 100 further includes: a lining bag placed in the box body 1. The heating element 3 is laid on the base 11 and is located below the lining bag.

[0067] Furthermore, as Figure 10 、 Figure 11 shown, the container 100 further includes: a thermostat 6 provided on the box body 1. The thermostat 6 is electrically connected to the electrical connector 4 through an external connecting wire 7. In this embodiment, the thermostat 6 is provided at the top of the side plate 12 of the box body 1. The electrical connector 4 is connected to the thermostat 6 through the external connecting wire 7, and the thermostat 6 is connected to the power supply through a wire.

[0068] The heating element 3 includes a core layer and a shell layer. Among them, the core layer includes multiple heating wires, and the multiple heating wires are resistance wires. After the resistance wires are energized, heat can be generated. The shell layer is made of epoxy resin material with a waterproof function. The shell covers the outside of the multiple heating wires, which can prevent liquid from entering the core layer and causing a short circuit. It should be understood that other waterproof shell layers can also be used, and epoxy resin is not restricted. In addition, the heating element 3 can also be replaced by other heating elements, such as ceramic heating elements, etc. In this article, the heating element 3 and other heating elements are collectively referred to as the heating layer. In this article, the heating layer is not limited to the heating methods listed above, as long as it can achieve the heating of the liquid in the inner lining bag. In addition, multiple layers of the heating element 3 can be stacked on the top surface of the base 11 or in the concave cavity of the base 11. For example, two heating pads can be provided, and the two heating pads can be hermetically connected by waterproof glue to improve the heating speed. The top surface of the base 11 is provided with a concave cavity, and the heating element 3 is laid flat in the concave cavity. It should be understood that the lower surface of the heating element 3 and the bottom wall of the concave cavity can be connected by the above methods, such as rivets, waterproof tapes, Velcro or magnetic attraction, etc. The connection method between the heating element 3 and the concave cavity is not restricted. In addition, the top surface of the heating element 3 is flush with the top surface of the base 11. When the side plate 12 is folded towards the base 11, it will not hit the heating element 3, avoiding damage to the heating element 3.

[0069] The preferred embodiments of the present invention have been described in detail above. However, it should be understood that if necessary, aspects of the embodiments can be modified to adopt aspects, features, and concepts of various patents, applications, and publications to provide additional embodiments.
