The solution of this task is, a kind of electric iron is proposed, it has the sheath that holds at least one heater and has a dismountable soldering tip that is fixed on the sheath, wherein heater is provided with a heat conduction contact-making surface one on the end face of soldering tip, the heating surface of soldering tip and this contact-making surface positioned opposite, wherein: contact-making surface and heating surface are whole parallel and constitute the heat conduction of not having the intermediate layer substantially and directly contact, and it is characterized in that: temperature sensor is arranged to and contact-making surface adjacency and being arranged between the heater coil of this contact-making surface and a calandria.
Because contact-making surface is parallel with heating surface on the whole, and do not have recessedly and/or protruding, thereby the processing of these faces is easy.Contact-making surface and heating surface are that the direct heat conduction in no intermediate layer contacts basically in addition, realized the gapless applying that touches by the parallel construction that this direct contact has realized the heat conduction between two faces best and has been aided with face, this is gapless to touch to fit and has avoided occurring such as heat insulation intermediate layers such as air cushions between contact-making surface and heating surface.
Because the longitudinal axis of soldering tip and welding head holder firmware and relative soldering tip with heating surface of contact-making surface or welding head holder firmware is the axis symmetry, thereby has further simplified the manufacturing process of soldering tip and welding head holder firmware.
In order to utilize the welding head holder firmware to be fixed on the electric iron soldering tip is easy, and make the mutual aligning between soldering tip and welding head holder firmware, contact-making surface can rotate relatively mutually with heating surface.By rotatable design and be aided with contact-making surface and the parallel construction of heating surface and directly touching between the two, can also more fully the air cushion between two faces be squeezed out in addition.
Contact-making surface and heating surface can have various profiles.These faces can be dihedral or oval-shaped.For to simplifying the consideration of relative rotation and manufacturing process, circular face is the preferred profile of contact-making surface and heating surface.When this situation,, will be favourable in addition if two circular face have identical radius.These two faces fully directly touch when this situation, and can not protrude in another face by a face.
When soldering tip was electroplated, especially on the heating surface in the radially outward outstanding soldering tip bounds that is as the criterion with soldering tip usually, the thickness of the material that electroplating can be a bit larger tham the distance to bounds.Even in order to guarantee when this situation not have directly touching of intermediate layer substantially between contact-making surface and heating surface, heating surface can be greater than contact-making surface.Adopt this mode contact-making surface only in bounds, directly to touch with heating surface.Can avoid electroplating the post processing of back when adopting this mode to heating surface.If for example realize this post processing by flat surface grinding certainly, heating surface can certainly be onesize with contact-making surface.
In a kind of simple embodiment, heater is a kind of electric heating calandria, and its end face towards soldering tip directly constitutes contact-making surface.
In order to realize the heat conduction between heater and soldering tip best, the contact-making surface of heater or calandria can bestly realize that by a kind of the material of heat conduction constitutes at least, and promptly the material by a kind of high thermal conductivity coefficient constitutes.This material for example can be copper, silver etc.
In order to quicken and to realize heater best, can insert the end section towards soldering tip of calandria in the sleeve pipe of making by the high thermal conductivity coefficient material to the conduction of the heat of contact-making surface.When this kind situation, at the distolateral formation contact-making surface of box face to soldering tip.Sleeve pipe quickens and has realized best the heat conduction of calandria to contact-making surface.
The sheath of electric iron can be made of many parts, wherein for example can be provided with means one electronic control component that is used to adjust the soldering tip temperature accordingly.Means are had to make hold electric iron and become possible heat insulation facility.Wherein heat insulation facility prevents by heater to the heat in the means outside is conducted.
When this situation, if for simplifying the structure of electric iron, sheath contains a dismountable welding head holder firmware fixed thereon, then is useful.This welding head holder firmware tightly is crowded together contact-making surface and heating surface mutually in its fixed position, thereby has realized directly touching of no intermediate layer.Welding head holder firmware as the soldering tip sleeve pipe is suitable complete tubular, and calandria or heater its end section at least are arranged in this soldering tip sleeve pipe, and wherein soldering tip removably is fixed on the free end of soldering tip sleeve pipe.
For the heating surface of when being fixed on sheath in easy mode the welding head holder firmware, realizing soldering tip simultaneously and the contact-making surface supporting with it directly touch and and soldering tip fixing on electric iron, the free end of soldering tip sleeve pipe has an opening that is used to stretch out soldering tip, wherein soldering tip have in its end towards heater one to small part around collar, this collar blocks the edge of opening of opening from following or back.Therefore can soldering tip be begun to insert in the opening from welding head holder firmware inside in easy mode, fit until its collar and edge of opening.Be rotated with or adopt the fixing of alternate manner by the welding head holder firmware on the electric iron sheath, the soldering tip heating surface is compressed on the contact-making surface of heater thereupon, thereby causes directly touching of these two faces.
With regard to directly the touching of heating surface and contact-making surface, what also will be illustrated is, the affiliated plane normal of these two faces is parallel or is slant dilation to the longitudinal axis of soldering tip or electric iron.To the longitudinal axis configured in parallel time, can realize two relative rotations that face is mutual.
What ensured two faces in the following ways directly touches and realizes simultaneously soldering tip stable fixing at the welding head holder firmware, and edge of opening and collar seamlessly fit together, wherein the both have mutually towards and the inclined-plane, location of applying mutually.
When this situation, if edge of opening radially inwardly towards Y stretch and for example only collar have inclined-plane, corresponding location, then enough.Cooperation by edge of opening and inclined-plane, location has realized the centralized positioning of soldering tip and firm fixing simultaneously.
When this situation, also can not adopt the inclined-plane, location of slant dilation and edge of opening and the corresponding binding face of collar can be basically to vertical extension of the longitudinal axis of soldering tip or welding head holder firmware.
For avoid also soldering tip being disassembled from the welding head holder firmware in dismounting welding head holder firmware, a block leaves at interval by the soldering tip upper process and with collar at least in part substantially radially outwardly.This block touches and also can avoid soldering tip to fall in advance in the welding head holder firmware with corresponding edge of opening when dismounting welding head holder firmware.Adopt this mode can be the welding head holder firmware with soldering tip by disassembling on the electric iron.
Block can be the annular protrusion around soldering tip in a simple embodiment.This annular protrusion should have and welding head holder firmware opening internal diameter equal outer diameters at least.Even when this external diameter was a bit larger tham the opening internal diameter, it was inner and also can disassemble from its inside also only just can be pressed into the welding head holder firmware to soldering tip with little force under the little situation of welding head holder firmware.
In addition, when having one between block and collar when small part is held the groove of edge of opening, also be proved to be useful.This groove also can be used as annular groove and extends along the whole circumference of soldering tip.
Above-mentioned groove for example also can be used to fixedly soldering tip when electroplating.Simultaneously, this groove both can be on the preceding extreme direction of the soldering tip that has or do not have block, with the collar of soldering tip the position of certain intervals is arranged, and also can be provided with in the position of being close to collar.Under any circumstance, the function of this groove all is, makes the edge of opening of welding head holder firmware local at least or partly in the embedded groove.Therefore even when the welding head holder firmware is disassembled on by electric iron, soldering tip also can utilize the interlocking of edge of opening and groove to be fixed by the welding head holder firmware.Certainly this groove also can be the annular groove around whole soldering tip, and wherein edge of opening can embed in this groove along the whole circumference groove.This groove can be arranged on the opposite side of soldering tip at least in useful mode, and wherein edge of opening is corresponding on these positions in the embedded groove.
When this situation,, then be proved to be useful if soldering tip and/or welding head holder firmware have one at least and be plurality of stepped serrations substantially in groove and/or edge of opening scope in addition.Adopt this mode groove and edge of opening just can be stuck with very little power.When changing soldering tip, soldering tip can be owing to because of carelessness by coming off in the welding head holder firmware.Also can there be fixing the welding head holder firmware of soldering tip to place on one side in addition and substitutes with another clamping piece that has corresponding soldering tip.The interlocking of also pressure releasing wearing and tearing or damage a little in addition soldering tip and edge of opening is also taken off it from the welding head holder firmware thereupon.
