Description
Technical field
The utility model relates to a kind of liquefied fuel gas igniter, particularly relates to a kind of air-out apparatus that is used for gas lighter.
Background technology
As everyone knows, a kind of modal form of liquefied fuel gas igniter is a gas lighter, is the example explanation background technology relevant with the utility model below with the gas lighter.
For gas lighter, generally adopting hydrocarbon compound is fuel, butane for example, and it is stored in the fuel tank of gas lighter with liquefied form.Therefore, gas lighter is the stronger consumer products of practicality, is again dangerous higher burning things which may cause a fire disaster and explosive.A lot of countries all classify gas lighter as the scope of dangerous goods, and its every performance indications are all had strict control.At present, the main performance index of gas lighter comprises the stability of maximum flame height, flame height and combustion stability etc.
When gas lighter used the fuel of particular types and quality, above-mentioned performance indications will be mainly decided by the air-out apparatus of the gas lighter gasification to liquefied fuel.About the gasification of fuel, generally can study from following two aspects: the one, gasification rate; The 2nd, the rate of gasification that interrelates with gasification rate.Herein, the gasification rate of fuel is meant (when lighting) when gas lighter is in running order amount of the liquefied fuel of generating gasification in the unit interval; And rate of gasification is meant the ratio (the liquefaction particle that still may contain fuel in the fuel that sprays in the air-out needle jet hole, this paper is called the aerosol body with this gas phase of fuel, the form that liquid phase may be mixed existence) of vaporising fuel and liquefied fuel in the aerosol fluid fuel that sprays when gas lighter is in running order from the air-out needle jet hole.
The gasification rate of fuel will determine the aerosol fluid fuel in the lighter flow channel and the pressure differential of surrounding air.This pressure differential will determine the speed that the aerosol fluid fuel sprays from the air-out needle jet hole, and final decision the flame height in lighter when work.And the efficiency of combustion of rate of gasification described aerosol fluid fuel will determine gas lighter in working order to a great extent time the and the stability of burning.If the rate of gasification of aerosol fluid fuel is not high, so not only can cause the efficiency of combustion of fuel low, waste fuel, but also " flash burn " phenomenon can appear.So-called flash burn phenomenon is meant some the liquefaction particle fully burning suddenly in the flame, the uneven phenomenon of a kind of burning of instantaneous bright spot (even may have slight cracker) occurs in the relevant position, and it also can influence the stability of flame height.Therefore, stable gasification rate, stable higher rate of gasification will improve the stability and the combustion stability of flame height.
On September 23rd, 1980 announced, name is called the United States Patent (USP) 4224020 of " Maximum-Flame-Height PressureRegulator for Gas Lighter " and has announced a kind of air-out apparatus that uses 100 in gas lighter, and its main technical schemes as shown in Figure 1.Air-out apparatus 100 comprises flame adjusting ring 125, air-out needle 127, be positioned at the Valve plug 129 (for example certain rubber tack) of air-out needle bottom, valve seat 131 with valve opening 119 and flow guiding structure 110 that is communicated with the fuel tank (not shown in figure 1) (for example form by sponge 113 and soup stick or suction core 111 by the adsorptivity bulk material for flow guiding structure 110), and air-out apparatus 100 has further comprised a control element pellicle 117 that limits maximum flame height.Wherein, the void ratio of pellicle 117 is to determine according to desired maximum flame height during fabrication, is generally 30% to 50%.In air-out apparatus 100, a hollow support 115 is arranged, its upper surface is that pellicle 117 provides support, with the top that pellicle 117 is fixed on valve seat 131 inner chambers and across between valve opening 119 and flow guiding structure 110.(for sake of convenience, this paper is fuel flow channels with flow guiding structure 110 upper surfaces to the channel definition between air-out needle 127 jet holes 123, and be the upstream flow passage with flow guiding structure 110 upper surfaces to the channel definition between the valve opening 119, be the downstream flow passage with the channel definition between valve opening 119 and air-out needle 127 jet holes 123.)
But utilizing air-out apparatus 100 mainly is the maximum gasification rate that has limited fuel, and it helps not quite to obtaining stable gasification rate, stable higher rate of gasification, and the flame height that can not guarantee lighter remains constant, makes a concrete analysis of as follows:
When lighter was not worked, the upstream flow passage also can be full of the aerosol fluid fuel, and this moment, these aerosol fluid fuels were called as " residual air ".The rate of gasification of residual air is lower, and liquefied fuel is more relatively.In air-out apparatus 100, because the volume of upstream flow passage is bigger, thereby residual air wherein is also more.When environment temperature raise, the volume of the vaporising fuel in the residual air can expand greatly, and liquefied fuel also can further gasify, and these all can make the air pressure of upstream flow passage increase greatly.Therefore, the phenomenon that what is called " burning that the people is taken aback " when the user uses the lighter igniting, will occur, that is: carry out the initial instant of ignition operation the user, the flame height of lighter can be well beyond the expection flame height that regulated originally or set, and returns to normal expection flame height after a moment.Even in fact under the situation that environment temperature does not significantly raise, thisly do not wish that the phenomenon that takes place also can exist to a certain extent.Having its source in of this problem:, thereby cause the gasification rate of ignition point very big because the upstream flow passage has stored certain residual air when lighter is not worked.But the big volume of upstream flow passage is when the gasification rate uniformity when initial causes negative effect to ignition operation, desired higher gasification rate and rate of gasification when guaranteeing but that lighter in working order (because in bigger space, easier the carrying out of gasifying).Therefore, before the utility model, it is infeasible solving this problem by the volume that dwindles the upstream flow passage.The volume that directly dwindles the upstream flow passage simply will reduce gasification rate and rate of gasification, makes lighter can not obtain sufficient stable fuel when normal ignition, causes more negative influence.
In addition, if the gas lighter that will use air-out apparatus 100 is upright come and when lighting from a kind of roughly inverted position, because the lower surface (towards that side of flow guiding structure 110) of pellicle 117 can adhere to more liquefied fuel particle, this can make, and the rate of gasification of gas lighter reduces, gasification rate is inhomogeneous.
In order to improve the fuel gasification rate, on December 20th, 1991 submitted to, name is called in No. 91232775.8, the Chinese utility model patent of " cigarette lighter nozzle structural improvement " and discloses a kind of air-out needle structure.The position of the side opening 121 of this air-out needle is higher, and air-out needle only has cavity in the first half.This patent thinks that such air-out needle structure has increased the contact area of fuel and air-out needle, can make gasification more abundant.But in fact the technical scheme of this patent can not address this problem well, because the interior cavity length of this air-out needle has been shortened greatly.Thereby, although this air-out needle structure has increased the contact area of fuel and air-out needle outer wall, but but reduced the contact area of fuel and air-out needle inwall, and reduced gasification space greatly, therefore in fact the technical scheme of this patent can not improve the fuel gasification rate well.
Exist too about the liquefied fuel gas igniter of the described variety of issue of gas lighter for other form above, therefore pressing for a kind of simple and effective technical scheme at present solves these problems.

The specific embodiment
The utility model provides a kind of air-out apparatus 200 that is used for the liquefied fuel gas igniter, shown in Fig. 2 A.Air-out apparatus 200 comprises a gasification stiffening device 400 in the flow channel at its upstream, and it is all-in-one-piece in this example.The inside of gasification stiffening device 400 is shaped on the air channel (or hole) 430 that runs through wherein.In gasification stiffening device 400, middle section and near zone thereof that this paper will comprise air channel 430 are called gasification part 410, and the part outside the gasification part 410 is called periphery 420.
When air-out apparatus 200 had pellicle 117, gasification stiffening device 400 preferably placed the below of pellicle 117, i.e. situation shown in Fig. 2 A.Preferably, the upper surface that can make periphery 420 is that pellicle 117 provides support, with pellicle 117 is fixing and across the top at the upstream flow passage.At this moment, the upper surface of gasification part 410 should be lower than the upper surface of periphery 420, with formation first gap 441 between the lower surface of the upper surface of gasification part 410 and pellicle 117.
Should have second gap 442 between the lower surface of gasification part 410 and the upper surface of flow guiding structure 110, so that flow into air channel 430 from the aerosol fluid fuel of flow guiding structure 110.
Gasification stiffening device 400 is preferably made by metal (for example copper), and this is the heat transference efficiency height because of metal, thereby can provide the liquefied fuel gasification required heat of gasification rapidly, helps the aerosol fluid fuel fully to gasify; Perhaps; gasification stiffening device 400 can select for use the material of other excellent adsorption to make; the aerosol body is when passing through gasification stiffening device 400 via air channel 430 like this; liquefied fuel particle wherein can be adsorbed; vaporising fuel then can pass through smoothly; and the liquefied fuel particle that is adsorbed generally can become more tiny particle, and their volatilization area significantly increases, thereby impels the aerosol fluid fuel fully to gasify.
Be used for the air-out apparatus 250 of liquefied fuel gas igniter according to another kind of the present utility model, shown in Fig. 2 B.Air-out apparatus 250 comprises a gasification stiffening device 500 in the flow channel at its upstream, and it is split type.Gasification stiffening device 500 comprises two independent parts, part that promptly gasifies 510 and periphery 520.Gasification stiffening device 500 has air channel (or hole) 530 to help the liquefied fuel gasification.To describe in detail later about specifically being provided with of gasification stiffening device 500 air channels 530.
In split type gasification stiffening device 500, gasification part 510 can be selected different materials for use with periphery 520.Particularly, gasification part 510 can by metal for example the material of copper or other excellent adsorption make, reason is the same; Periphery 520 then can be selected the PVC material for use, and this is because the PVC material price is cheap, and has certain elasticity and be easy to install.
When air-out apparatus 250 had pellicle 117, gasification stiffening device 500 was preferably placed at the below of pellicle 117, i.e. situation shown in Fig. 2 B.The upper surface of periphery 520 can be pellicle 117 and provides support, with pellicle 117 is fixing and across the top at the downstream flow passage.At this moment, has first gap 541 between the lower surface of the upper surface of gasification part 510 and pellicle 117.
For air-out apparatus 200 or 250, the air channel 430 or 530 the form that is provided with are normal direction area s (i.e. sectional area on fluted shaft line vertical direction when air channel to the influence of fuel gasification process, it is illustrated in the effective area that fuel in each air channel flows) summation S ' regularly (S ' be to determine) according to desired gasification rate and accessory size, for a certain amount of fuel, if can increase the contact area A of these fuel and air channel, promote that for the gasification stiffening device liquefied fuel gasification will be more favourable so.
The principal element that air channel 430 or 530 concrete form need be considered when design has 3: the normal direction area s of number n, each air channel and the tiltangle of air channel (angle of fluted shaft line and horizontal direction).The normal direction area s of each air channel there is no strict demand, if can allow the aerosol fluid fuel by, be not too greatly, generally approximately greater than 0.005mm
2The tiltangle of each air channel＞0 ° and＜=90 ° get final product, here need to prove, according to simple geometric knowledge as can be seen, when tiltangle=90 °, air channel 430 or 530 is actually straight trough or the through hole parallel with the longitudinal axis of gasify stiffening device 400 or 500; When 0 °＜tiltangle＜90 °, air channel is actually skewed slot (or inclined hole) or the helicla flute that the longitudinal axis with gasify stiffening device 400 or 500 forms an angle.In order to guarantee contact area A relatively large (note, this is for a certain amount of fuel), when tiltangle=90 °, the number n of air channel should be at least more than 2; When 0 °＜tiltangle＜90 °, the number of air channel can be (obviously, between two surfaces, skewed slot or spiral fluted length are greater than the length of straight trough, thereby contact area A is corresponding bigger) more than 1 or 1.
Under the certain situation of normal direction area summation S ', in order to increase contact area A, in the utility model, both can realize by the mode that increases air channel number n (selecting less s simultaneously for use), also can realize by the method that tiltangle is reduced.
For the preferred usually air channel that s is less, n is bigger of the air channel of straight trough form.For example, if determined S ', n generally is chosen as 3～12 so, and s then equals S '/n (if the s of each air channel equates); Certainly also can at first select n, n=S '/s (if the s of each air channel equates) with reference to the size of s.S generally is approximately 0.005～0.64mm
2, be preferably 0.04～0.25mm
2Air channel for skewed slot/helicla flute form, its parameter value is chosen with the air channel of straight trough form similar, difference is to consider difficulty (particularly θ angle hour) of skewed slot/spiral fluted processing, so when guaranteeing that the s value is a value in the preferred range, the n value tends to get less value.
Replacedly, gasification stiffening device 400 or 500 also can place the downstream flow passage, in the inner chamber of the air-out needle 127 of for example packing into, perhaps between valve opening 119 and pellicle 117.Here it is emphasized that, gasification stiffening device 400 or 500 preferably places the upstream flow passage, the below of pellicle 117 (if having pellicle) particularly, although this moment the upstream flow passage less be to be unfavorable for the factor that gasifies, but because gasification part 510 can help gasification, therefore remedy the adverse effect that the upstream flow passage reduces, and overcome the problem that produces when the described upstream flow passage of " background technology " part is big simultaneously.Especially, when air-out apparatus 200 or 250 has pellicle 117 and gasification stiffening device 400 or 500 when placing the below of pellicle 117, the rate of gasification of aerosol fluid fuel that arrives gasification stiffening devices 400 or 500 superjacent air spaces (for example first gap 541) via air channel 430 or 530 is higher, only contains less even does not have liquefied fuel.Therefore, the lower surface of pellicle 117 can not adhere to more liquefied fuel particle, even under the inverted situation of igniter, bigger liquefied fuel particle can be in gravity effect deposit not thereon yet, and a spot of less liquefied fuel particle on pellicle 117 the space and the downstream flow passage in can fully gasify fully, so air-out apparatus 200 or 250 can guarantee higher rate of gasification and stabilized uniform gasification rate.
For split type gasification stiffening device 500, air channel 530 both can be built on the outer surface of the inside of gasification part 510, the part 510 that gasifies or on the inner surface of periphery 520.Preferably assemble between gasification part 510 and the periphery 520 by friction tight mode.With reference to Fig. 3～Fig. 5 the gasification part 510 of separating and periphery 520 and compound mode thereof are described in detail below.
Fig. 3 A～Fig. 3 D is the stereogram of gasification part 510, shows 4 kinds of different specific implementation forms altogether, and gasification part 510 wherein includes head 511, step 512 and afterbody 513.Step 512 and afterbody 513 are not necessary, that is to say that gasification part 510 can be reduced to certain uniform shapes, and for example when the hole in the periphery 520 was circle, the reduced form of gasification part 510 can be a cylinder.Again for example, when only omitting afterbody 513, the gasification part 510 among Fig. 3 D is reduced to employed gasification part among Fig. 2 B.
For the gasification part 510 among Fig. 3 A～Fig. 3 C, when it had step 512, then the upper surface of step 512 can have second air channel 531 (shown in Fig. 5 B, Fig. 5 D and Fig. 5 E), and it extends radially outwardly; Perhaps second air channel 531 also can be arranged on the lower surface of periphery 520 (size of second air channel 531, the setting of number and air channel 530 are similar); Otherwise if there is no second air channel 531 then must have third space 543 (second air channel 531 and/or third space 543 are communicated with air channel 530 fluids) between the lower surface of the upper surface of step 512 and periphery 520; Has the 4th gap 544 between the inwall of the outer surface of step 512 and valve seat 131; Has second gap 542 between the upper surface of the lower surface of step 512 and flow guiding structure 110.And for the gasification part 510 among Fig. 3 D under situation with step 512, do not have the problem in third space 543 and the 4th gap 544 yet, should guarantee to have second gap 542 between the upper surface of its lower surface and flow guiding structure 110
The size in first gap 541, second gap 542, third space 543 and the 4th gap 544 also has no special requirements, if be easy to the aerosol fluid fuel by, be not too greatly, particularly, the size in these gaps can be 0.1～1mm.
In Fig. 3 A, gasification part 510 is not provided with air channel 530; In Fig. 3 B, air channel 530 is the spiral slots that tilt to extend downward step 512 upper surfaces along the outer surface of gasification part 510; In Fig. 3 C, air channel 530 is many straight troughs that extend downward step 512 upper surfaces along the outer surface of gasification part 510 abreast; In Fig. 3 D, air channel 530 is the through holes that are positioned at gasification part 510 inside.
Fig. 4 A～Fig. 4 C is the stereogram of periphery 520, shows 3 kinds of different specific implementation forms altogether.In Fig. 4 A, periphery 520 is not established air channel 530; In Fig. 4 B, air channel 530 is the spiral slots that tilt to extend downward step 512 upper surfaces along the inner surface of periphery 520; In Fig. 4 C, air channel 530 is many straight troughs that extend downward step 512 upper surfaces along the inner surface of periphery 520 abreast.
In fact, no matter air channel 530 be arranged on the outer surface of gasification part 510, on the inner surface of the inside of gasification part 510 or periphery 520, it all can be arbitrary shape, as long as the flow channel via gasification part 510 can be provided.
Fig. 5 A～Fig. 5 E shows the multiple preferred compound mode that gasification part 510 and periphery 520 are combined formed gasification stiffening device 500.Gasification stiffening device 500 shown in Fig. 5 A～Fig. 5 C be respectively by the periphery 520 of Fig. 4 A respectively with gasification part 510 combined formation of Fig. 3 B～Fig. 3 D, wherein the gasification part 510 of Fig. 3 C has second air channel 531 herein; Gasification stiffening device 500 shown in Fig. 5 D and Fig. 5 E is combined by the periphery 520 of the gasification of Fig. 3 A part with Fig. 4 B～Fig. 4 C, and gasification part 510 wherein all has second air channel 531.
Fig. 6 shows an exemplary embodiment of igniter of the present utility model, and it has the air-out apparatus shown in Fig. 2 B (certainly, it also can use the air-out apparatus shown in Fig. 2 A).Among Fig. 6, igniter 600 is direct lighting type piezoelectric lighters, and it comprises shell 611, fuel tank 613, piezo-electric device 615, seesaw 619, presses hand 619 and air-out apparatus 250 shown in Figure 2.When pressing when pressing hand 619, the head of piezo-electric device 615 can move down thereupon, thereby by seesaw 619 air-out needle 127 is upwards lifted, and Valve plug 129 is upwards lifted, so that whole fuel flow channels conducting, fuel sprays from jet hole.When fuel sprays from jet hole, the piezoelectric voltage of piezo-electric device 615 can be near jet hole 123 the generation electric spark, fire fuel.Certainly, it should be understood that, igniter with the utility model air-out apparatus is not limited to the direct lighting type piezoelectric lighter, but can comprise the liquefied fuel gas igniter of any kind, the for example lighter of piezoelectricity or non-piezoelectric type (for example using flint) or burning torch etc., the perhaps lighter of direct lighting type, side turn over, sideslip type or push button or burning torch etc.
