Description:
FIELD OF THE INVENTION 
     The present invention relates to an iron, especially an iron of which the steam brush and the base of the metal soleplate are disassembled. 
     BACKGROUND OF THE INVENTION 
     The existing irons are disposed with a metal soleplate, which has a heating pan, in the lower portion of the housing. A thermoregulator is disposed inside the housing to control the power to the heating pan and then change the heat radiation of the metal soleplate; the housing is disposed with thermoregulator knob, which is directly connected to the level lever of thermoregulator to regulate the level of the electricity output of the thermoregulator. 
     To expand the use mode of the iron, combining a steam brush set and a base set to be a biservice iron. 
     The steam boiler of electrical heated is disposed inside the housing of the steam brush set. The steam outlet of the steam brush is connected to the outside from the bottom of the housing. The electrical wire is led into the housing from the rear portion and connected to the switch of the steam boiler. Turn on the switch, the steam boiler is energized by the external power, the water inside the steam boiler turns into steam and spurts out from the bottom of the housing. A handle is disposed on the housing of the steam brush set for independently usage of garment ironing. 
     The heating pan is disposed at the bottom of the housing of the base set. The thermoregulator is disposed inside the housing to control the power to the heating pan and then change the radial of the heating pan. The housing of the base set is disposed without handle, but the housing of the base set is disposed with an accommodation room for the steam brush set and for locking the lower of the steam brush set. The steam brush set is locked to the base set, forming an iron with a handle for ironing. 
     However, how to realize the thermoregulator knob on the steam brush to disassemble connect to the level lever of the thermoregulator on the base set to regulate the level of the energy output of the thermoregulator is a much vexed problem for the designer. In the disassemble state, the rotation positions of the thermoregulator knob on the steam brush and the level lever of the thermoregulator on the base set are random, making it difficult to make sure that the thermoregulator knob and the level lever of the thermoregulator are rotating synchronously when the steam brush set is locked to the base set. Besides, it&#39;s difficult to ensure that the level indicator for the thermoregulator knob can exactly read the present level of the thermoregulator when the thermoregulator knob is randomly connected to the level lever of the thermoregulator. 
     SUMMARY OF THE INVENTION 
     The object of the present invention is to provide with a biservice iron, in which the thermoregulator knob and the level lever of the thermoregulator are rotating synchronously when the steam brush set is locked to the base set. 
     Moreover, the biservice iron is provided that the level indicator for the thermoregulator knob can exactly read the present level of the thermoregulator when the thermoregulator knob is randomly connected to the level lever of the thermoregulator. 
     The technical proposal of the present invention is: a biservice iron includes a steam brush set, a base set and a thermoregulator knob, the thermoregulator knob includes an external knob which is rotatably disposed on the housing of the steam brush set and an inner knob which is rotatably disposed on the housing of the base set, the inner knob is connected to the level lever of the thermoregulator on the housing of the base set, the external knob and the inner knob are connected to each other in socket way with cylinder of which the cross section is equilateral polygon or star-shaped of equilateral polyhedral angle. 
     In another preferred embodiment, the cylinder of which the cross section is equilateral polygon or star-shaped of equilateral polyhedral angle between the external knob and the inner knob is conical surface of slightly inward contraction, the free end of the lever between the external knob and the inner knob is disposed with the corresponding cone of inward contraction and equilateral polygon or star-shaped of equilateral polyhedral angle. The external knob is easy to inserted connected to the inner knob, and it can achieve an automatically modification effect with the cone of inward contraction and equilateral polygon or star-shaped of equilateral polyhedral angle in the free end of the lever between the external knob and the inner knob during the inserting.
