Detailed Description

The invention is further described with reference to the following figures and examples.

First embodiment, referring to fig. 1-5, an electric warmer comprises a housing 1, a handle assembly 2, an upper disc 3, an electric heating tube 4, a lower disc 5, an electric control module 6, a switch button assembly 7, and a base 8. Casing 1 is cylindricly, and casing 1 includes upper segment 11, middle section 12 and hypomere 13, is equipped with a plurality of louvres 14 on the middle section 12, and the hypomere 13 of casing 1 is close to middle section 12 department and is equipped with installation jack 15, is equipped with constant head tank 16 on the casing 1 of installation jack 15 periphery. The top end of the electric heating tube 4 is fixed on the upper disc 3, the handle component 2 is fixed on the top surface of the upper disc 3, the top surface of the electric control module 6 is provided with a lower disc 5 for heat insulation, and the bottom end of the electric heating tube 4 penetrates through the lower disc 5 to be installed in the electric control module 6.

Handle subassembly 2, go up disc 3, electric heating tube 4, lower disc 5 and automatically controlled module 6 assemble the back whole insert casing 1 inner chamber from 1 top of casing, handle subassembly 2 is fixed at 1 top of casing, 11 inner chambers in upper segment and the 12 inner chambers in middle section are separated to

upper disc

3, 12 inner chambers in middle section and 13 inner chambers in hypomere are separated to lower disc 5, it makes in the 12 inner chambers of the section of concentrating of the heat dissipation of electric heating tube 4 with lower disc 5 promptly, and through 14 external heat dissipations of louvre to the casing, base 8 is fixed in casing 1 bottom and with automatically controlled module 6 fixed connection.

The electronic control module 6 comprises a micro switch 61 and an electrical box 62, the trigger end 60 of the micro switch 61 is arranged in the electrical box 62, and the electrical box 62 outside the trigger end 60 of the micro switch 61 is provided with a clamping rail 63.
