DETAILED DESCRIPTION

[0020] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments; based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0021] Embodiment one, by Figures 1-5 The utility model discloses a base main body 1 is provided with the inner tray 2, the inner tray 2 is provided with the heating disc 3, the health pot is placed on the heating disc 3, the lower end middle part of the inner tray 2 is installed with the switch fixed seat 4, the switch fixed seat 4 is embedded with the power microswitch 5, the upper end middle part of the inner tray 2 is connected with the sleeve 6, the sleeve 6 is equipped with the connecting rod piece 7, the lower part of the connecting rod piece 7 extends to the lower side of the inner tray 2 and the handle of the power microswitch 5 and moves in contact, the spring 8 that plays the role of elastic jacking is equipped between the connecting rod piece 7 and the inner tray 2, the upper end of the sleeve 6 is equipped with the heat insulation silica gel 9, the heat insulation silica gel 9 is protruding, and the top protruding part of the heat insulation silica gel 9 extends to the upper end surface of the heating disc 3, the upper end middle part of the heat insulation silica gel 9 is embedded with the temperature sensing probe 10, and the lower part of the temperature sensing probe 10 is embedded with the connecting rod piece 7.

[0022] The connecting rod piece 7 includes a fixed plate 701, guide rods 702 connected to both sides of the lower end of the fixed plate 701, limit hooks 703 connected to the lower parts of the guide rods 702, and a pressing rod 704 connected to the lower end middle part of the fixed plate 701, wherein the pressing rod 704 is used to contact and open / close the power microswitch 5.

[0023] The upper end of the fixed plate 701 is symmetrically connected with connecting rods 705, and the same probe limiting ring 706 is connected between the upper parts of the two connecting rods 705.

[0024] The outer wall of the inner tray 2 is uniformly distributed with four supporting legs 11, and the inner part of the base main body 1 is uniformly distributed with four connecting columns 12, wherein the supporting legs 11 and the connecting columns 12 are connected through screws, and the stability of the inner tray 2 and the whole structure is ensured.
