Abstract

The utility model relates to a base frame with automatic alarm for an electric iron, comprising the base frame, a bimetal sheet, and an automatic alarm. When the electric iron is used, is switched on and heated to the required temperature, after the heat energy is conveyed to the bimetal sheet, an N and an M points are automatically communicated according to the heat expansion and cold contraction principle, and the automatic alarm gives an alarm. The utility model has simple structure, low cost, high safety, and high work efficiency.

Description

Automatic electric iron safety pony sill of reporting to the police

The utility model is a kind of safety device of reporting to the police automatically when flatiron heats needed temperature of being used for.

Present widely used plain edition electric iron, during ironing clothes flatiron is kept flat or places vertically on object and heat, in the heating process user be know flatiron temperature how, touch, know the temperature of flatiron through hand commonly used with spitting, so unavoidable hand is scorched, in case the user leaves the scene, the danger that causes fire is just arranged.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and provides a kind of simple in structure, and cost is low, and is easy to use, the safe and reliable pony sill of reporting to the police automatically when electric iron is heated to needed temperature.

This practical purpose realizes by following measure: the making with thin wire of electric iron pony sill (1) outer surface nickel plating, be provided with four frame legs (3) below the pony sill (1), the upper edge is provided with two iron wires (4) that its middle of iron wire frame (2) is provided with the supporting iron plate, two iron wires (4) middle is installed on the outside and is loaded on the interior bimetal leaf (7) of glass tube (6) with what scale copper (5) was wrapped, bimetal leaf (7) N point is received the N line of alarm device, bimetal leaf (7) M point is received the M line of alarm device, warning device adopts dc source, the CTC285 series integrated circuit of operating voltage 3V.Warning device and power supply are installed in the bottom surface casing (10) of base seat (1), are placed in four plastics footmuffs (11) on four frame legs of pony sill (1).

The accompanying drawing face is described as follows:

Fig. 1 is a top view structural representation of the present utility model;

Fig. 2 is an A-A cross-sectional view of the present utility model;

Fig. 3 is an integrated circuit schematic diagram of the present utility model.

5---copper sheet 6---glass tube 7---bimetal leaf 8---power supplys

9---loudspeaker 10---casing 11---footmuffs.

Below in conjunction with embodiment to this practical being described in further detail.When opening the electric iron that lies on the base seat (1) when using electric iron and being heated to needed temperature, heat energy passes on the bimetal leaf (7) by scale copper (5) and glass tube (6), open the shrinkage principle by heat, N on the bimetal leaf (7) is that anodal M is the N of negative pole, the effect of M point heat energy is communicated with down, by adopting dc source, operating voltage is the oscillator work that the CTC285F series circuit of 3V is formed, and reports to the police thereby the signal of telecommunication amplifies a band loudspeaker through triode.

The utility model is simple in structure, and cost is low, and is safe and reliable, improves work efficiency, applied widely, easy to use.
