[0027] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0028] A stainless steel-clad electric hot pot base includes an inner frame and a stainless steel profile 2, the outer wall of the inner frame is covered with the stainless steel profile 2; the inner frame is composed of two or more frame parts connected and fixed together by plug-in connection, threaded bolt connection, screw connection, or snap-on connection. Example 1

[0029] In this embodiment, a stainless steel-clad electric hot pot base is provided, wherein the individual frame parts are connected and fixed together by left and right plug-in connection, threaded bolt connection, screw connection, or snap-on connection, and then a stainless steel profile 2 is coated on the outer wall of the plugged-in inner frame. Example 2

[0030] In this embodiment, if Figure 1 The stainless steel-clad electric hot pot base shown includes a lower frame 4 and an upper frame 5, the outer walls of the lower frame 4 and the upper frame 5 are covered with a stainless steel profile 2; a socket 3 is installed between the side walls of the lower frame 4 and the upper frame 5 through a sliding groove structure, which facilitates the disassembly and assembly of the socket 3 between the lower frame 4 and the upper frame 5. Example 3

[0031] In this embodiment, if Figure 1-10 The shown is a stainless steel-clad electric hot pot base, wherein a plurality of fixing rods 10 are installed at the bottom of the upper frame 5, and a plurality of fixing tubes 6 are connected to the interior of the lower frame 4. A first through groove 14 is provided at one end of the fixing rod 10, and the two openings of the first through groove 14 are elastically connected to the limiting blocks 23. A second through groove 15 is provided at one end of the fixing tube 6, and one end of the two limiting blocks 23 respectively extends to the two openings of the second through groove 15. A threaded tube 20 is installed at the bottom end of the fixing tube 6, and a threaded column 19 is installed on the internal thread of the threaded tube 20. Two slide grooves 16 are provided inside the fixing tube 6, and push rods 22 are provided inside the two slide grooves 16. The top ends of the two push rods 22 extend to the bottoms of the two limiting blocks 23 respectively, and the bottom ends of the two push rods 22 are movably connected to the threaded columns 19.

[0032] When connecting and fixing the lower frame 4 and the upper frame 5, first insert one end of the fixing rod 10 into the fixing tube 6, then press the upper frame 5 downward, and the upper frame 5 drives the fixing rod 10 to slide in the fixing tube 6. When the fixing rod 10 drives the two limit blocks 23 to contact the inner side surface of the fixing tube 6, the limit block 23 is forced to move in a circular arc on the surface of the fixed shaft 13. At this time, the torsion spring 9 receives the force of the limit block 23 and synchronously generates torsion and accumulates force, and one end of the limit block 23 slides along the inner wall of the fixing tube 6. After one end of the limit block 23 moves to the position corresponding to the second through groove 15, the torsion spring 9 drives the limit block 23 to move into the second through groove 15 in the opposite direction through its own elastic potential energy. At this time, the top of the fixing tube 6 contacts the bottom of the upper frame 5, and one end of the limit block 23 rests on the inner top surface of the second through groove 15, which is used to limit the position of the fixing tube 6, thereby improving the stability of the connection between the fixing tube 6 and the fixing rod 10, and improving the stability of the connection between the lower frame 4 and the upper frame 5.

[0033] When disassembling the lower frame 4 and the upper frame 5, it is only necessary to rotate the threaded column 19, and the threaded column 19 will move spirally in the threaded tube 20. At the same time, the threaded column 19 drives the movable block 18 to move, and the movable block 18 moves toward the fixed rod 10. The movable block 18 drives the two push rods 22 to slide in the two slide grooves 16 through the fixed block 21, so that the two push rods 22 can push the two limit blocks 23. After being forced, the two limit blocks 23 move to the first through groove 14. At this time, the fixed rod 10 can be easily removed from the fixed tube 6, which facilitates the separation operation between the lower frame 4 and the upper frame 5.

[0034] A mounting rod 24 is installed at one end of the threaded column 19 located inside the threaded tube 20, and a movable block 18 is movably sleeved on the surface of the mounting rod 24. A stopper 17 is installed at one end of the mounting rod 24, and the surface of the stopper 17 contacts the top of the movable block 18. Two fixed blocks 21 are installed on the side of the movable block 18, and the bottom ends of the two push rods 22 are respectively installed on the surfaces of the two fixed blocks 21. During the spiral movement of the threaded column 19, the threaded column 19 drives the mounting rod 24 to rotate inside the movable block 18. As the threaded column 19 drives the movable block 18 to move during the movement, the stability of the threaded column 19 when driving the two push rods 22 to move is improved.

[0035] Two symmetrically arranged fixed shafts 13 are installed inside the first through groove 14, and the other ends of the two limit blocks 23 are movably sleeved on the surfaces of the two fixed shafts 13, and the two ends of the two fixed shafts 13 are movably sleeved with torsion springs 9. The two ends of the two torsion springs 9 are respectively connected to the two symmetrical side surfaces of the limit blocks 23 and the inner side surfaces of the first through groove 14. After the limit blocks 23 are subjected to force, the limit blocks 23 move in a circular arc on the surface of the fixed shaft 13, and at the same time, the limit blocks 23 drive the torsion springs 9 to generate torque. After the limit blocks 23 are received in the first through groove 14, it is convenient to separate the fixed tube 6 and the fixed rod 10; after the torsion spring 9 drives the limit blocks 23 out of the first through groove 14 in the opposite direction through its own elastic potential energy, one end of the limit blocks 23 moves to the second common 15, which is used to limit the position between the fixed tube 6 and the fixed rod 10, thereby improving the stability of the connection between the lower frame 4 and the upper frame 5.

[0036] The sides of the lower frame 4 and the upper frame 5 are covered with a stainless steel profile 2, which improves the appearance quality and durability and is convenient for cleaning.

[0037] A connecting plate 7 is installed on the inner side surface of the lower frame 4 , one end of the connecting plate 7 is installed on the bottom end of the fixed tube 6 , and the connecting plate 7 can be used for connecting and fixing the lower frame 4 and the fixed tube 6 .

[0038] A bottom plate 8 is matched and installed in the inner hole of the lower frame 4. A plurality of grille holes are provided on the surface of the bottom plate 8. The bottom plate 8 is used to protect the base, while the grille holes can be used for heat dissipation.

[0039] In this solution, the electric heating tube 11 and the heat conducting plate 1 in the electric heating pot are arranged in the upper frame 5, and the control circuit board is arranged in the lower frame 4. The button electrically connected to the control circuit board is installed on the surface of the stainless steel profile 2. The socket 3 is connected to the control circuit board through a wire, and the control circuit board is connected to the electric heating tube 11 through a wire. The pot body 12 is installed on the surface of the upper frame 5, and the heat conducting plate 1 is in contact with the pot body 12.

[0040] The remaining structures of this embodiment are the same as those of the second embodiment and will not be described in detail.
