Abstract
The utility model relates to an electric iron, comprising a shell, a switching circuit arranged on the shell, and a heat conduction bottom plate arranged on the bottom part of the shell. The utility model is characterized in that the heat conduction bottom plate is provided with a PTC heating element. As a PTC heat-sensitive element is used as the heating element, the utility model can automatically regulate the power and the working temperature.
Description
The utility model relates to a kind of electric iron.
Present electric iron generally adopts resistance wire as pyrotoxin, is insulating materials with the mica sheet, and its shortcoming is that volume is big, the power consumption height, and can't regulate power and suitable operating temperature voluntarily according to operating mode.
The purpose of this utility model is that a kind of electric iron will be provided.This electric iron adopts the PTC thermo-sensitive material as heater element, can regulate power and suitable operating temperature voluntarily to satisfy requirements of one's work according to operating mode.
The utility model comprises housing, be located at the switching circuit on the housing and be located at the conductive sole plate of housing bottom, and the characteristics of its structure are: conductive sole plate is provided with the PTC heater.
Below in conjunction with drawings and Examples the utility model is specifically described.
Fig. 1 is the utility model organigram, removes pressing plate 6,1 expression housings among the figure; 2 expression PTC heaters, 3 expression base plates; 4 expression shift bars; 5 expression power lines.
Fig. 2 is the A-A cutaway view of Fig. 1,6 expression pressing plates among the figure; 7 expression PTC temperature-sensitive elements; 8 expression high temperature insulation rubber sleeves; 9,10 expression battery lead plates.
With reference to accompanying drawing, electric iron of the present utility model comprises plastic casing, is located at the switching circuit on the plastic casing, is located at the conductive sole plate (aluminium sheet) 3 of plastic casing bottom and is located at PTC heater 2 on the conductive sole plate.
The PTC heater is made up of PTC temperature-sensitive element 7, the battery lead plate 9,10 and the high temperature insulation rubber sleeve 8 that are positioned at the upper and lower side of PTC temperature-sensitive element.It is the square shape, is embedded in the square groove 11 of conductive sole plate upside.The conductive sole plate upside also is provided with in order to the fixing pressing plate 6 of heater.
The utility model course of work is as follows: when the battery lead plate 9,10 of the upper and lower side of PTC temperature-sensitive element through switching circuit and power connection, the PTC temperature-sensitive element gets electric heating; When the conductive sole plate of flatiron contact with wet cloth, and when temperature was reduced, the resistance of PTC temperature-sensitive element reduced, and electric current increases, so the increase of the heating power of PTC temperature-sensitive element; When the conductive sole plate of flatiron contact with the cloth of doing, and when temperature is risen, the resistance increase of PTC temperature-sensitive element, electric current reduces, and heating power reduces.
Therefore the utility model, can regulate power and operating temperature according to operating mode voluntarily owing to adopted the PTC thermo-sensitive material as heater element.This product is energy-conservation, economical, and is easy to use, and its market prospects are considerable.
