Figure 1 As well as the patent number CN202020759677.4 previously applied for by the inventor, the name is a patent scheme of an electric pressure cooker. Traditional electric rice cookers or electric pressure cookers are generally provided with an inner layer cylinder 2 in the pot body 1, and the bottom of the inner cavity of the inner layer cylinder 2 is connected to a heating plate 4, and the inner pot 3 is placed in the inner cavity of the inner layer cylinder 2 and the bottom of the inner pot 3 is in contact with the heating plate 4, and then the inner pot 3 is heated by the heat of the heating plate, and the inner pot 3 is used to hold food. Therefore, the solid food or liquid in the inner pot 3 is relatively easy to leak into the inner cavity of the inner layer cylinder 2, thereby contaminating the heating plate 4. In the heating basin structure in this embodiment, Figures 1 to 6As shown, the heating plate 4 includes a plate body 40 and a support leg 41 connected to the bottom of the inner pot 3. The plate body 40 and the support leg 41 are detachably connected. A connecting structure 42 for fixing the plate body 40 to the bottom of the inner pot 3 is also provided between the plate body 40 and the inner pot 3. The heating plate 4 is designed as a split structure so that the main part of the heating plate 4, the plate body 40, can be easily disassembled for cleaning or repair during use or maintenance.

[0025] In this embodiment, the connection structure 42 adopts the following structure: Figure 2 and Figure 6 As shown, the connecting structure 42 includes a connecting column 421 arranged at the bottom of the disk body 40, and the bottom of the connecting column 421 is rotatably connected to a clamping part 420. The bottom of the inner layer tube 2 is provided with a mounting hole 21 for the connecting column 421 to pass through the bottom of the inner layer tube 2 from top to bottom. The clamping part 420 is provided with a protruding clamping portion 422, and the edge of the mounting hole 21 is provided with a matching notch 211 for the clamping portion 422 to pass through.

[0026] As a preference, Figure 6 As shown, the clamping member 420 is connected to the disc body 40 by a thread. Preferably, a screw hole is provided on the connecting column 421, and a screw portion is provided on the top of the clamping member 420 to match it, so that the clamping member 420 can rotate relative to the disc body 40. Figure 6 As shown, the inner tube 2 is provided with a limiting protrusion 212 on one side of the matching notch 211 for preventing the clamping portion 422 from moving and thus preventing the clamping member 420 from rotating. During operation: the clamping member 420 is screwed into the disc body 40 through a threaded connection, and a gap is left between the clamping member 420 and the bottom end of the first connecting column 421, that is, it does not need to be tightened. The disc body 40 is placed on the support leg 41, and the connecting column 421 passes through the mounting hole 21. The clamping portion 422 of the clamping member 420 is aligned with the matching notch 211 and passes through the matching notch 211, so that the clamping member 420 is located on the lower side of the mounting hole 21. At this time, the clamping member 420 is rotated so that the clamping portion 422 is staggered with the matching notch 211. In this embodiment, In the embodiment, the screw hole of the connecting column 421 and the screw portion of the clamping part 420 are set as right-hand threads, and the setting position of the limiting protrusion 212 is set on the rear side of the matching notch 211 along the tightening direction of the clamping part 420. In this way, when tightening the clamping part 420, when the clamping part 422 approaches the limiting protrusion 212, it is blocked, preventing the clamping part 420 from continuing to tighten. In this way, when installing, you only need to rotate the clamping part 420 to a certain angle, and you do not need to tighten it completely. When disassembling, you only need to rotate it to a certain angle.

[0027] In order to facilitate users or maintenance personnel to disassemble the heating basin 4 without disassembling other parts of the product, Figure 2As shown, the bottom of the pot body 1 is provided with an operating channel 11 corresponding to the mounting hole 21 and capable of allowing a tool body to be inserted into the clamping part 420.

The bottom of the clamping part 420 is provided with an operating groove 423 for operating the tool body. In this embodiment, the tool body refers to a general screwdriver, and the operating groove 423 is a cross slot or a straight slot. Of course, other tool bodies and operating grooves 423 of other shapes can also be used.

[0028] In order to facilitate the alignment and stable placement of the tray body 40 when it is installed on the support legs 41, as shown in FIG. Figure 3 and Figure 4 As shown, a mating protrusion 411 is provided on the top of the support foot 41, and a mating groove 401 matching the shape of the mating protrusion 411 is provided on the bottom of the disk body 40. In this embodiment, the surface of the mating protrusion 411 is a spherical convex surface, and the mating groove 401 is a spherical concave surface matching it.

[0029] In detail, Figures 2 to 5 As shown, the bottom of the inner layer tube 2 is provided with a first through hole 22 for the bottom end of the support leg 41 to pass through, and the bottom end of the support leg 41 is connected to a locking component 5 that can be stuck on the lower side of the first through hole 22. The locking component 5 can adopt a general bolt or a combination of a bolt and a gasket. It is only necessary that the head of the locking component 5 can be stuck on the lower side of the first through hole 22 so that the support leg 41 cannot move upward. The bottom of the inner cavity of the inner layer tube 2 is provided with supporting bosses 23 on both sides of the first through hole 22, and a strain gauge 6 for detecting the pressure value is placed on the supporting boss 23. The middle part of the strain gauge 6 is provided with a second through hole for the support leg 41 to pass through, and the middle part of the support leg 41 is provided with a stepped portion 412 that can be stuck on the upper side of the second through hole.

[0030] As a preference, Figure 5 As shown, the disc body 40 is provided with an arc-shaped heating tube body 43, and the two ends of the heating tube body 43 are connected with plug pins 44. The bottom of the pot body 1 is provided with a plug interface 12 for power supply. When the disc body 40 is placed on the support leg 41, the plug pin 44 and the plug interface 12 are plugged into each other. Of course, the plug pin 44 and the plug interface 12 can also be omitted, and a traditional integrated structure can be adopted. Since the heating tube body 43 in the traditional structure is connected to the power wire, the power wire is flexible, and the length of the power wire is preset to be longer, so that the disc body 40 can be moved after disassembly.
