Fig. 7 is the synoptic diagram of the preferred feeding mechanism that links to each other with flatiron of the present invention.

With reference to above each figure, the whole flatiron of representing with label 10 of the present invention is made up of following each several part basically among Fig. 1: one microscler, and section is circle or avette and so on main body 12; And heating member or instrument 14.Aforementioned body 12 forms the supporting member of above-mentioned instrument 14, and this technical field known method of instrument 14 usefulness, for example screw 16, are connected in the front end of aforementioned body 12.As shown in the figure, the instrument 14 with conventional shape is to use metal, and for example brass is cast, and according to the present invention, all places of portion is provided with different conduit of length and pedestal within it, so that by an end nozzle supply may command and standard compliant steam.Specifically, according to a preferred embodiment, instrument 14 has a pair of conduit that interconnects, constituted a pair of vestibule 18,20, be used for atomized liquid, also have a formation to be used for placing the vestibule 22 of the pedestal of conventional heating member 24, with a hole 26 that is used for placing the thermopair 28 that links to each other with described heating member 24.Vestibule 18,20 preferably is parallel to each other, and as shown in Figure 3, can be arranged on the same plane of instrument 14 bottoms, also can be as shown in Figure 4 and Figure 5, and arranged superposed.Heating member 24 is preferably made with the element of resistance and so on, and with a common cable 30 power supply, this cable passes the main body 12 of the handle that forms flatiron 10, and passes the back from the back of main body 12 and link to each other with power supply.

Have one in the vestibule 18,20 at least, extend to fore-end near instrument 14 at length direction, form a little opening 32 in its corresponding section, this opening 32 has constituted the outlet nozzle of steam.Vestibule 18,20 radially is communicated with each other by one or more connections duct 34; In a preferred embodiment, have only one to connect duct 34, be positioned at rear portion, the place relative with nozzle 32 near vestibule 18,20.

According to another characteristics of the present invention, as the expression in detail of Fig. 4 institute, described vestibule 18,20 inwall is a uneven surface 36, this uneven surface, preferably process, or can obtain, or when casting tool 14, directly obtain by the machine-tooled method of tapping and so on by continuous or discrete screw thread.

Opposite with known the phenomenon that liquid is warmed up, the shape of vestibule 18,20 inwalls has increased the metal of instrument 14 inside and the contact area of liquid significantly, and is very effective for the liquid that reduces effusive not atomizing from nozzle 32.In fact, when using flatiron 10, instrument 14 heated objects 24 are heated to above 100 ℃ temperature, even may be above 200 ℃; The drop that enters the liquid (normally water) in the evaporation vestibule 18,20 can be encased by a near vapor film the hot metallic surface immediately, has the trend of " distillation ", and can not contact with described surface.If the inwall of vestibule 18,20 is smooth-flat-surfaces, its consequence is, water droplet may be accompanied by steam and flow out together, and this will increase the impaired danger of part of goods flatiron.

By cutting thread, the machine-tooled method of tapping and so on, liquid and metal are at vestibule 18, the contact area of 20 inside has increased, thereby also allow to generate a successive step or a plurality of adjacent step,, be used for further improving surface tension so that cover suitable material thereon, the two alternate tangential forces that promptly act on vestibule 18,20 inwall metallic surfaces and enter liquid one solid system that forms between the liquid in the vestibule.

Described tectum can by, for example, very thin one deck inorganic salt (material of calcium chloride and so on) form, and use in the near future at instrument 14, being dissolved in inorganic salt in the liquid can nature, be deposited on the uneven surface of vestibule 18,20 inwalls equably; Obviously, this tectum can be before instrument 14 uses to the acquisition of the water of the suitable band additive of vestibule 18,20 supply temperatures.In Fig. 4, the described tectum of label 38 expressions, it is 10 fens uniform very thin tectums, has covered the whole uneven surface of the atomizing vestibule 18,20 of instrument 14.The long-time flatiron 10 that uses, the tectum material that accumulates on vestibule 18,20 uneven surfaces can increase, and fills and leads up the uneven surface of label 40 indications gradually, and the aperture of described vestibule is reduced.If do not use distilled water, this increase trend can spontaneous generation.Therefore, can know by inference, when the beds of precipitation acquire a certain degree, be necessary often to remove the beds of precipitation; With the instrument of milling apparatus and so on, cleaning work can be carried out at an easy rate, but because the rough form of described vestibule 18,20, the sedimentable matter of uneven surface 40 inside but can not be removed.As a result, carry out cleaning work after, liquid one solid two alternate interfacial tensions do not change, so instrument 14 can re-use immediately, and without any the danger of leaking hot liquid from nozzle 32.Best, as shown in Figure 4, a metal lining is installed in the exit of the vestibule 18,20 that is sealing with the device (not shown) of common screw plug head and so on.The internal diameter of this lining preferably can be fixed on the exit of described vestibule with simple press fit method, does not stick with glue or additive method fixed possibility but also do not get rid of.The suitable machining tool of the internal diameter of lining 42 inserted in the vestibule 18,20 carry out cleaning work, correspondingly, make the top of uneven surface of the described vestibule of the unlikely damage of diameter of cleaning tool.

By initial machining or the vestibule 18 that obtains when the casting tool 14, the roughness of 20 inwalls, and the tectum that after this forms along this inwall can make the breakup of drop of liquid, warms up phenomenon thereby eliminated, and the result has guaranteed to have only steam to spray from nozzle.Vestibule 18, the 20 passing hole channels 34 this design of UNICOM have each other formed the path of a labyrinth shape, for entering instrument 14 and have enough length from the liquid that nozzle 32 is gone out, thereby have time enough to change atomizing state into.

Flatiron 10 of the present invention, best, but and nonessentially link to each other with a supply system, this system makes liquid pass through an atomisation unit and air mixed before entering vestibule 18,20.Described atomisation unit as label 44 indications in Fig. 5 and 7, is made of a tubular body arranged inside 46, includes two and is used for carrying empty G﹠W to enter the

conduit

48,50 of hybrid chamber 52 respectively.Tubular body arranged inside 46 is stretched into a pipe 54 that diameter is less in the place ahead of described hybrid chamber 52, pipe 54 the known device of front end 56 usefulness is contained in exporting of vestibule 18,20 of instrument 14.Among Fig. 5, pipe 54 front end 56 is packed in the vestibule 18, and vestibule 18 is positioned on the vestibule 20 in instrument 14.

Conduit

48,50 connects supply system by common coupling device, shown in the label among Fig. 7 60.Described system is made up of a loop, and this loop is by a strainer 64 and reducing valve 62 supply air, and reducing valve 62 is used for regulating pressure and flow.Above-mentioned loop is divided into two branch roads that separate 66,68, and article one branch road 66 links to each other with the conduit 48 of atomisation unit 44 by a mid-magnetic valve 70.The second branch road 68 in loop inserts in the water tank 72, and the back of coming out links to each other with the conduit 50 of described atomisation unit 44 by a mid-magnetic valve 74.A pressure control device, pressure warning unit 76 for example, the air pressure in the control loop preferably makes it between the 0.005-0.5 crust.Feeding mechanism-startup, for example by the button 12 on the handle portion 12 that protrudes in flatiron 10 by ', system will open simultaneously and lay respectively at branch road 66, near 68

magnetic valve

70,74, guarantee that a large amount of air and water enter the hybrid chamber 52 of atomisation unit 44 respectively, and in this mixing.Jia Ya gas-water mixture enters pipe 54 then, and enters in the vestibule 18 of instrument 14 by managing 54 front end 56.The mixture atomizing that is dimensioned to suitable air-water of the endoporus of pipe 54 and front end 56 thereof.Finish or 12 ' time of release button in working cycle, carry the magnetic valve 74 in the branch road not to close, carry the magnetic valve 70 of the branch road of air then to continue unlatching several seconds at zero point, with water residual in the clearing device 44.This has just prevented to follow the generation of the unwanted steam of generation when the operator does not re-use supply system in the short period of time; In fact, the pipe 54 of atomisation unit 44 has at least in the vestibule 18 of a part of insertion instrument 14, is heated high temperature by thermal conduction, generally is higher than 200 ℃.

By supply system 60, entering in the vestibule 18,20 of instrument 14 is not the water of droplet-like, but a kind of mixture of the air-water that has atomized; Like this, just quicken the formation of steam in the instrument 14 and from nozzle 32, sprayed steam.In addition, by system 60, might accurately limit the water yield that is atomized, the water yield preferably is no more than 3 ml/min, and under any circumstance the water yield can accurately be regulated.

By above-mentioned description as can be known, the present invention has many tangible advantages.

Flatiron of the present invention can make the steam local distribution that sprays very apace from the nozzle 32 of instrument 14 on the goods that will press; Because the labyrinth shape vestibule 18,20 of instrument 14 of the present invention, their interior shape and relevant tectum be not so exist the danger of the water droplet of ejection heat.The operator of flatiron operation can work fast, and needn't be before with instrument 14 flatirons, moistening by hand goods.By atomisation unit 44, flatiron 10 links to each other with feeding mechanism 60, thereby allows accurately to supply the water of minimum and the atomization process of acceleration instrument 14 inside.

Above-described and the present invention in appending claims just describes in an exemplary fashion, should be appreciated that the present invention can have multiple improvement and variation, yet all these drops on also in the design scope of the present invention.

For example, instrument 14 can have the evaporation vestibule 18,19 of different numbers, and not necessarily be designed to directly, so that extend into more or less labyrinth, have again, the uneven surface of described vestibule inwall can be discontinuous and/or discrepant, to form darker or more shallow roughness.In addition, can in flatiron 10, inject liquid, though preferably connect with above-mentioned supply system 60 by any device.

At last, can also do various variations to the structure or the position of the component of forming the whole flatiron of the present invention.
