[0057] The embodiments of the present utility model are described below with reference to the accompanying drawings.

[0058] One embodiment of the present utility model relates to a container 100. As Figure 1 、 Figure 4 、 Figure 5 、 Figure 7As shown, the container 100 includes: a box body 1, a heating element 3, and a plurality of electrical connectors. The top of the box body 1 has a receiving opening 10. The heating element 3 is disposed inside the box body 1. The heating element 3 is electrically connected to any one of the plurality of electrical connectors, and the electrical connector is detachably connected to the heating element 3, and at least one of the plurality of electrical connectors can be configured to extend out of the box body 1 through the receiving opening 10 after being electrically connected to the heating element 3. In this example, two electrical connectors are taken as an example. One is a long-line connector 42, which can be used as an external wiring. After directly connecting the heating element 3, it extends from inside the box body 1 to the top of the box body 1 to extend out and dock with a power supply or a temperature controller 6, without opening a hole in the box body 1; the other is an internal connector 41, which can be used as an internal wiring, penetrates the wall surface of the box body 1, and docks with a power supply or a temperature controller 6 through an external connecting wire 7. The two electrical connectors can be switched and used according to actual needs. In other embodiments, the number of electrical connectors is not limited to this.

[0059] Since the heating element 3 is disposed 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 the heating efficiency, and greatly improving the operation convenience. And a plurality of electrical connectors are provided, and different electrical connectors are selected to be electrically connected to the heating element 3 according to needs. When the selected electrical connector can extend out of the box body 1 through the receiving opening 10, there is no need to punch holes in the box body 1; when the selected electrical connector cannot extend out of the receiving opening 10, an opening is made in the box body 1 to meet different usage requirements.

[0060] As Figure 17 shown, the electrical connection end of the heating element 3 has a magnet 31, and a molded part 32 is disposed on the magnet 31 to cover the magnet 31. One end of the electrical connector connected to the heating element 3 has a galvanized round iron 43, and the galvanized round iron 43 will be attracted to the magnet 31 to be assembled in place. At this time, the electrical connector and the heating element 3 are in electrical contact, realizing the electrical connection between the electrical connector and the heating element 3.

[0061] Furthermore, as Figure 2 、 Figure 3 and Figure 4 shown, at least one of the plurality of electrical connectors is a long-line connector 42. The long-line connector 42 has a first plug-in end 421 connected to the heating element 3, a second plug-in end 422 for external connection, and a connecting wire 423 connecting the first plug-in end 421 and the second plug-in end 422. After the first plug-in end 421 of the long-line connector 42 is connected to the heating element 3, the second plug-in end 422 of the long-line connector 42 extends out of the box body 1 through the receiving opening 10.

[0062] In addition, as Figure 3 and Figure 4As shown, the heating element 3 is laid on the bottom of the container 100, and the first plug-in end 421 is bent. The first plug-in end 421 has a first plug-in head 4211 for inserting into the electrical connection end of the heating element 3, and a first plug-in body part 4212 extending by bending from the first plug-in head 4211. The first plug-in body part 4212 extends towards the receiving opening 10 and is connected to the connection line 423. Thus, after the heating element 3 is laid, the long linear connector 42 can also extend outside the box body 1 by bending the first plug-in end 421, and the first plug-in end 421 is close to the side plate 12 of the box body 1, so that the connection line 423 extends along the side plate 12 of the box body 1 towards the receiving opening 10, without occupying the space inside the box body 1.

[0063] As Figure 1 , Figure 14 and Figure 15 shown, the wall surface of the box body 1 has an operable area 13 that can be used to form a through hole. When the electrical connector to be used is the built-in connector 41, a through hole is formed by opening a hole in the operable area 13, and the built-in connector 41 can be configured to be inserted into the through hole. Thus, the built-in of the built-in connector 41 can be realized, and it can be extended without protruding to the receiving opening 10.

[0064] Furthermore, as Figure 8 , Figure 10 , Figure 11 shown, the container 100 further includes: a fixing seat 2 arranged in the through hole, and one end of the built-in connector 41 away from the heating element 3 is configured to be inserted and positioned in the fixing seat 2.

[0065] In addition, as Figure 1 shown, a hole-blocking plate for closing the through hole is arranged on the box body 1, and the hole-blocking plate is connected to the wall surface of the box body 1 through a weak part, and the hole-blocking plate forms the operable area 13. Through this setting, it is convenient to form the through hole.

[0066] Furthermore, the fixing seat 2 is detachably connected to the box body 1 or is an integral part of the box body 1.

[0067] Furthermore, as Figure 8 , Figure 9 shown, the fixing seat 2 has a mounting hole 20 for the insertion of one end of the built-in connector 41. The upper wall surface of the mounting hole 20 has a mounting through surface 24, a mounting fixing surface 25, and a mounting positioning surface 26 that are connected in the direction from inside the container 100 to outside the container 100. The built-in connector 41 is a plug, and one end of the built-in connector 41 away from the heating element 3 is a wiring end head, and the wiring end head has a top surface of the end head that cooperates with the upper wall surface of the mounting hole 20 and a bottom surface of the end head that faces away from the top surface of the end head. The top surface of the end head is used to insert into the mounting hole 20 along the mounting through surface 24, the mounting fixing surface 25, and the mounting positioning surface 26, and is used to abut and position against the mounting fixing surface 25 and the mounting positioning surface 26.

[0068] Further, as shown in Figure 8 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , the installation plane passing through the face 24 and the installation positioning face 26 is a horizontal plane, and the installation fixing face 25 is an inclined plane extending upward from the installation plane passing through the face 24 to the installation positioning face 26. The top surface of the terminal head has a terminal head top inclined face 411 with the same slope as the installation positioning face 26 and a terminal head positioning face 412 connected to the terminal head top inclined face 411. After the wiring terminal is installed in the fixing base 2, the terminal head top inclined face 411 abuts against the installation fixing face 25, and the terminal head positioning face 412 abuts against the installation positioning face 26 for positioning.

[0069] Further, as shown in Figure 8 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , the bottom surface of the terminal head has a terminal head bottom inclined face 413 extending upward in a direction away from the heating element 3, and the terminal head bottom inclined face 413 has the same slope as the terminal head top inclined face 411. When the wiring terminal is inserted into the installation hole 20 from the side facing the inside of the container 100 to the installation hole 20, the terminal head top inclined face 411 moves along the installation plane passing through the face 24, and the terminal head bottom inclined face 413 moves along the lower wall surface of the installation hole 20.

[0070] Specifically, as shown in Figure 8 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15As shown in the figure, when installing the heating element 3 and the built-in connector 41, the built-in connector 41 is inserted into the electrical connection end of the heating element 3. The heating element 3 is placed 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. Then, push the heating element 3 so that the end of the built-in connector 41 away from the heating element 3 moves into the mounting hole 20 of the fixing seat 2. During the process of inserting the built-in connector 41 into the fixing seat 2, the heating element 3 and the built-in connector 41 tilt together. The bottom inclined surface 413 of the end moves along the bottom surface of the box body 1 into 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 head is inserted into the mounting hole 20. The heating element 3 is pushed into place, and the heating element 3 is laid flat. 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 head abuts against the lower wall surface of the mounting hole 20. At this time, both the heating element 3 and the built-in connector 41 are placed horizontally, realizing the insertion and positioning of the built-in connector 41 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 head. When it is necessary to remove the heating element 3 from the box body 1, it is similar to the method 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. Continue to pull the heating element 3 to make the built-in connector 41 slide along the fixing seat 2, realizing the removal of the heating element 3 and the built-in connector 41 from the box body 1.

[0071] Further, as Figure 8 , Figure 9 shown, 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 built-in connector 41 away from the heating element 3 is inserted into the area formed by the surrounding of the outer frame 222.

[0072] In addition, as Figure 8 , Figure 9 shown, the seat body 21 has a contact surface 211 facing outside the container 100, and a sealing member 23 is provided around 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 is in sealing contact with the contact surface 211. The flip cover 22 and the seat body 21 are hinged together by an elastic member 28, and the elastic member 28 applies a torsion force towards covering the mounting hole 20 to the flip cover 22. The elastic member 28 can be a torsion spring. The torsion spring is connected to the seat body 21 and the flip cover 22 through a connecting shaft 29. Without other external forces, the torsion spring abuts against the flip cover 22 to seal and cover the mounting hole 20.

[0073] Specifically, as Figure 16 shown, the container 100 includes: a base 11 and two pairs of opposite side plates 12, and 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 formed 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, which will not affect the folding of the box body 1.

[0074] Furthermore, the container 100 further includes: a lining bag placed inside the box body 1. The heating element 3 is laid on the base 11 and is located below the lining bag.

[0075] Furthermore, as Figure 16 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. In this embodiment, the thermostat 6 is provided at the top of the side plate 12 of the box body 1, and the built-in connector 41 is connected to the thermostat 6 through an external connecting wire 7, and the thermostat 6 is connected to the power supply through a wire. The long-line connector 42 extends at least to the receiving port 10 and is connected to the thermostat 6.

[0076] The heating element 3 includes a core layer and a shell layer. Among them, the core layer includes a plurality of heating wires, and the plurality of heating wires are resistance wires, and heat can be generated after the resistance wires are energized. The shell layer is made of epoxy resin material with a waterproof function, and the shell covers the outside of the plurality of 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 limited. 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 realize the heating of the liquid in the 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. A concave cavity is provided on the top surface of the base 11, 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., and the connection method of the heating element 3 and the concave cavity is not limited. In addition, the top surface of the heating element 3 is flush with the top surface of the base 11, and 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.
