Detailed Description

The following describes the embodiments of the present invention with reference to the accompanying drawings.

Fig. 1, 2 and 3 show: the utility model discloses whole outward appearance is unanimous basically with traditional electric iron. One end of a plug 21 is connected with a power cord 20, the other end of the power cord 20 connected with the plug 21 is embedded into a handle from an opening at the rear end of a lower shell 19 to be connected with a circuit board 18, the circuit board 18 is fixedly connected by two fastening screws 7, a switch 17 is fixed at a groove at the rear end of the upper shell 11, a shaft 16 and a pulley 15 are fixed at an opening at the middle of the upper shell 11, a rubber ring 14 is sleeved on the pulley 15, an indicator light 13 is connected with a temperature sensor 12, the indicator light 13 is fixed at the opening at the front end of the upper shell 11, a lead at the tail of the temperature sensor 12 is connected with the circuit board 18, the temperature sensor 12 is fixed at the inner side of the front end of the lower shell 19, the upper shell 11 and the lower shell 19 form the handle, one side of a disc of a guide tube 10 is connected with the handle, the other side of the disc is connected with a connecting body 6, a filter element 9 is fixed in an air guide tube 8, and a tube opening of the air guide tube 8 is aligned with a middle hole below a sleeve 5, the air duct 8 is connected with the sleeve 5 through two fastening screws 7, the four fastening screws 7 are square to fix the connector 6, the guide tube 10 and the handle, the connector 6 is connected with the front end of the sleeve 5, the heat insulation layer 4 is arranged on the inner side of the heating core 3, the front end of the heating core 3 is arranged on the inner side of the sleeve 5, the unheated part of the front end is connected with the front end of the sleeve 5, the positioning screw 2 fixes the soldering bit 1, and the soldering bit 1 is connected with the heating core 3.
