DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0043] like Figures 1 to 14 As shown, the food heating device of the present invention comprises a heating seat 1, a pot body 2 and a pot cover 3, wherein the pot cover 3 is arranged on the pot body 2, and the pot body 2 is placed on the heating seat 1. The pot cover 3 has a spoon 4 and a decoration 5 that can lift the pot cover 3, and the decoration 5 can be a leaf. The pot body 2 can be in the shape of a pumpkin.

[0044] The heating seat 1 is composed of an upper cover 6 and a lower cover 7. The lower cover 7 is hollowed out inside, and the upper cover 6 has a lip 23 extending to the middle of the lower cover 7. The upper cover 6 is installed on the lower cover 7 through the lip 23, which plays a positioning role and can also be fixed by screws. The structure necessary for heating is set inside the lower cover 7, which can be a prior art and will not be elaborated in detail here.

[0045] A heating coil 24, a heat insulating seat 25, a circuit board 26 and a connecting assembly 27 are arranged inside the lower cover 7. The heat insulating seat 25 is arranged in the middle of the circuit board 26, the heating coil 24 is mounted on the upper end of the heat insulating seat 25, and the connecting assembly 27 is mounted on the bottom wall of the lower cover 7 and located at the lower end of the heat insulating seat 25. An arc plate 28 for limiting the heating coil 24 is arranged on the heat insulating seat 25.

[0046] The connecting assembly 27 includes a pressure member 29 and a mounting seat 30 for placing the pressure member 29. The pressure member 29 is connected to the electrode 31 of the heating coil 24, and the pressure member 29 is composed of a hinge portion 32, a pressure portion 33 and a contact portion 34. A blocking end 35 is provided on the hinge portion 32, and the blocking end 35 cooperates with the inner wall of the placement groove 36 to limit the rotation angle of the pressure member 29. When the pressure member 29 is rotated, the rotation angle of the pressure member 29 is limited by the cooperation of the inner wall of the placement groove 36 and the blocking end 35.

[0047] A contact plate 37 is provided at the lower end of the contact portion 34, and the contact plate 37 is in contact with and connected to the electrode 31. A through hole 38 is provided at the lower end of the mounting seat 30, and the contact plate 37 is connected to the contact portion 34 by bolts, and the bolts pass through the through hole 38 and are placed in the insertion hole 39 to connect the contact plate 37 to the contact portion 34. At the same time, a guide slope 40 is provided at the end of the electrode 31, and the guide slope 40 is conducive to the insertion of the electrode 31 and lifts the contact plate 37. When the electrode 31 is not inserted, there is a certain distance between the contact plate 37 and the through hole 38, so that the electrode 31 can directly lift the contact plate 37 through the guide slope 40, so that the contact plate 37 and the electrode 31 are in contact and energized.

[0048] The mounting seat 30 is fixed in the lower cover 7 by screws, and is provided with a placement groove 36 for mounting the pressure member 29 and an insertion hole 39 for inserting the electrode 31. The hinge portion 32 of the pressure member 29 is hinged in the placement groove 36 by a hinge rod 41, and the mounting seat 30 is also provided with a through hole 42 through which the contact portion 34 passes, and the contact portion 34 passes through the through hole 42 to contact and connect with the electrode 31. The through hole 42 is in the shape of an inverted trapezoid, and a second gap 44 is left between the contact portion 34 and the inner wall of the through hole 42.

[0049] The mounting seat 30 is also provided with a baffle 45, the pressure-applying portion 33 and the baffle 45 are provided with a positioning hole 46, a limiting spring 47 is provided in the positioning hole 46, and the mounting seat 30 is provided with a wiring hole 48, and a fastening bolt 49 is provided on the wiring hole 48 and vertically arranged thereon. The limiting spring 47 is in a compressed state, ensuring that the pressure-applying member 29 applies pressure to the contact plate 37, ensuring that the contact plate 37 and the electrode 31 can be in close contact.

[0050] There is a first gap 43 between the bottom wall of the placement groove 36 and the pressure member 29 , and the first gap 43 ensures that the pressure member 29 still has space to apply pressure downward.

[0051] A positioning block 50 is provided at the lower end of the heat insulating seat 25, and a support seat 51 and a positioning seat 52 are provided on the lower cover 7. The support seat 51 is used to cooperate with the heat insulating seat 25 to slide, and a positioning opening 53 is provided in the middle of the positioning seat 52. The positioning block 50 is used in conjunction with the positioning opening 53. After the heat insulating seat 25 slides on the support seat 51 and the positioning seat 52, the electrode 31 can also be smoothly inserted into the insertion hole 39, and the guide slope 40 lifts the contact plate 37, so that the circuit is connected.

[0052] At the same time, at the charging port on the lower cover 7, there is an electric wire connected to the plug, the electric wire is connected to the circuit board 26, and the electric wire on the circuit board 26 is connected to the wiring hole 48 on the mounting base 30, so that the external circuit can be connected to the connecting component 27 and the electrode 31 is connected at the same time.

[0053] The lower cover 7 has a charging port 8, and an external power cord can be inserted into the charging port 8. The charging port 8 has an openable fan plate 9, and the fan plate 9 is arc-shaped. One end of the fan plate 9 is hinged between the upper cover 6 and the lower cover 7 through a hinge shaft 10, and the upper end of the charging port 8 is open.

[0054] The hinge shaft 10 is provided with an elastic member 11 , which is a torsion spring 12 , and has a support leg a and a support leg b. The support leg a contacts the fan plate 9 , and the support leg b contacts the inner wall of the charging port 8 .

[0055] One end of the fan plate 9 has a mounting chamber 13 for placing the elastic member 11, and the leg a of the elastic member 11 contacts the inner wall of the mounting chamber 13. The elastic member 11 is in a compressed state in the mounting chamber 13. When installing, the elastic member 11 is compressed and then installed in the mounting chamber 13.

[0056] One end of the elastic member 11 contacts the fan plate 9, and the other end contacts the inner wall of the charging port 8. The fan plate 9 also has a movable groove 14, and the charging port 8 has a T-shaped stopper 15 that matches the movable groove 14. The movable groove 14 is an inverted T-shape, and the movable groove 14 is composed of an entry port 16 and a movable port 17, and the movable port 17 is located at the upper end of the entry port 16. The T-shaped stopper 15 is composed of a stopper 18 and an extension portion 19, and the height of the stopper 18 is less than the height of the entry port 16, and the width of the extension portion 19 matches the width of the movable port 17.

[0057] When the fan plate 9 is in a closed state, the T-shaped limiter 15 is in the movable opening 17 , and when the fan plate 9 is in an open state, the T-shaped limiter 15 and the entrance opening 16 are at the same plane height, which facilitates the elastic member 11 to directly pop the fan plate 9 out of the charging port 8 .

[0058] The charging port 8 also has a mounting groove 20, the axis of which coincides with the axis of the hinge shaft 10, and a support spring 21 is provided in the mounting groove 20, which is sleeved on the outside of the hinge shaft 10. When the fan plate 9 is in a closed state, the support spring 21 is in a compressed state, and when the support spring 21 is compressed, it is completely located in the mounting groove 20. When the fan plate 9 is in an open state, the support spring 21 can lift up the fan plate 9 and support the fan plate 9, which is between a compressed state and a natural state, and the upper end of the support spring 21 extends out of the mounting groove 20.

[0059] The outer wall of the fan plate 9 is provided with anti-slip grooves 22 to facilitate the user to push the fan plate 9.

[0060] The height of the charging port 8 is H1, the height of the fan plate 9 is H2, and the height of the movable groove 14 is H3, where H1=H2+H3.

[0061] The elastic force of the legs of the elastic member 11 is F1, and the elastic force of the support spring 21 is F2, where F1>F2. When the fan plate 9 is in a closed state, the legs a and b of the elastic member 11 can apply a force of F1 to the fan plate 9. Since the support spring 21 is in a compressed state at this time, a force of F2 will be applied to the fan plate 9. Since F1>F2, the T-shaped stopper 15 can be kept in the movable opening 17, and the F2 applied by the support spring 21 will not lift up the fan plate 9.

[0062] Furthermore, the support spring 21 can also play an auxiliary role when the user applies an upward thrust Fn to the fan plate 9. At the same time, when the fan plate 9 is opened, the support spring 21 can support the fan plate 9 so that the inlet 16 on the fan plate 9 and the T-shaped stopper 15 are kept at the same level, which is conducive to the user directly pushing the fan plate 9 to rotate, so that the T-shaped stopper 15 enters the inlet 16, and then the user pushes the fan plate 9 downward so that the movable opening 17 limits the T-shaped stopper 15.

[0063] A method for using a food heating device comprises the following steps:

[0064] S1, hinge the pressure member 29 to the placement groove 36 through the hinge rod 41, and place the contact portion 34 through the through hole 42 into the insertion hole 39;

[0069] In addition, the second assembly method is to assemble the fan plate 9 between the upper cover 6 and the lower cover 7. The second assembly method includes the following steps:

[0070] S1, hinge the pressure member 29 to the placement groove 36 through the hinge rod 41, and place the contact portion 34 through the through hole 42 into the insertion hole 39;
