Description

Electrically heated hair-curler

Technical field

The utility model relates to electric heater unit, relates in particular to a kind of electrothermal hair waving pin that is used to improve looks, and the utility model device is applicable to general beauty parlor and family.

Background technology

The present electrically heated hair-curler that generally is used for hairdressing can be summed up as four kinds of structures as shown in Figure 1 substantially, and the electrically heated hair-curler shown in Fig. 1 a is to form heater element by a heating line is wrapped on the fine fibre pipe; The electrically heated hair-curler of Fig. 1 b then is the heating line to be wrapped on the mica support form heater element.These two kinds of electrically heated hair-curlers all are to utilize the convection current of air to transmit heat, and the efficient of therefore transmitting heat is lower, and programming rate is slower.Also useful PTC heating resistor is made heater element (Fig. 1 c); Or utilize (Fig. 1 d) of thin ceramic heating sheet.Though these two kinds of curlers directly contact by metal and transmit heat, but the heating area of these two kinds of curlers is much smaller than the logical area of dissipation of its outside metal, and the thermal power of the PTC heater element of unit volume or ceramic heating plate is less, therefore also causes to heat up slowly; Because it is too big that the volume of electrically heated hair-curler can not be done, and the shape of PTC heating resistor and ceramic heating plate is too thin, if attempt is by adding the high-power temperature that improves heater element, then heater element will explosion.

Generally speaking, the power of existing electrically heated hair-curler is not high, does not generally reach 200 watts, so programming rate is slower, heats under conventional indoor temperature, when treating its serviceability temperature that is raised to 180～200 degree Celsius, sometimes even will be above 15 minutes.Therefore user regular meeting waits for impatiently.For reaching the convenient standard of using, generally require to be raised to 180～200 degree serviceability temperatures Celsius fast from normal temperature in 60 seconds after the electrically heated hair-curler energising heating.

Summary of the invention

The technical problems to be solved in the utility model is that providing a kind of can high-powerly heat, and thermal inertia is less, the electrically heated hair-curler that programming rate is fast.

The technical scheme that the utility model adopted is, manufacture and design a kind of electrically heated hair-curler, comprise: electrothermal tube, be hinged on the electrothermal tube and form the intermediate plate of pressing hand that has of clip by spring and electrothermal tube, the handle of wiring board is arranged in fixedlying connected with an end of electrothermal tube.Described electrothermal tube comprises metal tube, and the bobbin that is tied with heating wire of inner edge cover, and is insulated layer between heating wire and the metal tube and separates.The electrical lead of heating wire is drawn from the inner chamber of bobbin, and is connected with wiring board in the handle.This structure has guaranteed that be a kind of tight contact than large tracts of land, more powerful heater element with metal tube as the hair-waving working surface, the heat that heater element sends is directly passed to metal tube by conduction pattern, so metal tube can be warming up to operating temperature after the short time.

Described bobbin can select for use wall thickness between 0.5～3.0 millimeter, can bear the above high temperature of 800 degree, the composite pipe that mica is made; Perhaps select the ceramic pipe of wall thickness between 1～2 millimeter for use.Described heating wire is generally the nichrome heating wire, is wrapped in the outer surface of bobbin, connects the electrical lead of heating wire again, then constitutes heater element.Described insulating barrier is rolled on the heating wire that winds for using mica paper earlier, wraps up in around the mica paper outside with Kapton again.These concrete measures have guaranteed the feasibility and the reliability of technique scheme.

Described bobbin at one end on the tube wall, is embedded with temperature-sensitive element.This temperature-sensitive element has temperature-resistant insulation layer edge to be enclosed within its outside metal heat-conducting spare, and heat-conducting piece has closely with the inwall of metal tube and contacts.The electrical lead of temperature-sensitive element is drawn from the inner chamber of bobbin, and is connected with wiring board in the handle, detects the different temperature value of control, makes the each point serviceability temperature reach stable state.

Described two that is tied with the bobbin of heating wire respectively has a metallic sheath that has a step to be embedded in the inwall of bobbin and metal tube, makes the utility model device safer and more reliable.

Compared with prior art, electrically heated hair-curler of the present utility model has following beneficial effect:

1. power is big, and heat time heating time is short, and programming rate is fast, and the user waits and is no more than 1 minute;

2. the heating in the electrothermal tube is reliable, can explosion, and as safe as a house, long service life.
