When fuel vapor in the use and gas can be common to same stove and accessory,, must improve to make and use the electronic ignition structural improvement of fuel vapor as raw material because of the electronic ignition device of stove and accessory commonly used is to be that fuel is made with gas specially.

The burning-point of gas is low, and the jet power of its igniting is big could to attract a large amount of air-breathing completing combustion gas simultaneously.And the burning-point of fuel vapor is higher, and the air content height after stirring in bucket with air, is difficult for lighting under concentrating in that brute force is jet.Therefore must in the conduit of electronic ignition or net groove, add obstacle oil gas mouth and to the conduit in lightning point plate space after a while or net groove, add the oil gas that obstacle oil gas thing comes the powerful ejection of obstacle before slightly, relaxed so that oil gas ejection is flowed, just very easily make fuel vapor or gas light converter nose with the state of big fire.

Can change into stove and accessory with regard to the adjustment of the required a large amount of air-breathing and required little air of fuel vapor of gas in addition operates outward, but because of general family adopts the brand of Gas cooker and constructs not of uniform sizely, so be difficult to must be divided into two classes to set firmly the size installation elements: (one) is to use middle stove and accessory; (2) new product specification; Various brands in just using are promptly with the most simple and economical method, promptly bore a perforation in the ear of former suction plate, after tying an iron wire again and passing the furnace side face, iron wire is connected to a baffle ring, can push-and-pull adjust air-breathing oral pore, realize a kind of adjustment mode in the circle footpath of 50 to 60 degree scope; Another kind of default being used on the new stove, the central forward direction of air-breathing adjustment plate is added helical spring be butted on air entry, make its external diameter be set as forward marginal ridge lip, again its about 70 degree are set as the cloudy dentation of perforation, and identical of engagement side is established the positive gear of about 50 degree, make both be engaged on switch valve in 50 to the 60 degree scopes, with between the maximum air demand and the minimum inspiratory capacity of fuel oil that are suitable for gas, the front and back of these sun gear central authorities are to the tail end that connects an axostylus axostyle, inserting the rear wall or the U font cross bar that are through at stove and accessory makes it to reverse with clamping before and after the energy, but unlikely moving forward and backward, after the axostylus axostyle that protracts passes antetheca, fix in addition, add at the axostylus axostyle front end again and turn round cover so that do fuel oil and the adjustment index of the inspiratory capacity that gas is required by a pole socket.

Structure of the present utility model is: fuel vapor because will with the shared stove and accessory of gas, at first to solve the problem of igniting, because the burning-point of gas is low than fuel oil, its igniting oral pore of giving vent to anger is big slightly, light easily, because jet power is big more, the air of following is many more, the probability that gas is lighted is high more, otherwise the gas burning-point of fuel oil is higher, be difficult under bigger fuel injected gas, catching fire, therefore, if will be easy to igniting, must be by fuel-injection pore to the space between electronics lightning needle plate, and be provided with the iron net of pipe cap shape, reverse the iron net, torsionspring, the irregular a kind of bar wherein such as iron wire that reverses as barrier gas, make and spray oil gas behind barrier, relax and flow, just igniting easily.

The air-breathing adjustment structure of converter nose, lower at gas because of burning-point, the essential external air of relatively large absorption, by air entry enter cooperate combustion-supporting, otherwise its burning-point of fuel oil is higher, and required external air capacity is little, under this difference, adopt when cooking, with the raging fire of fuel oil as main source; When boiling soup, then change and use with gas, this switching all needs to adjust inspiratory capacity, so that this kind fuel can reach sufficient completing combustion, therefore, be very inconvenient only by the manual mode operation structure that originally was located in the stove, for conveniently carrying out the outer adjustment of stove, two kinds of methods can be arranged, and a kind of is to be applied to old stove, and being bored a hole by the overhanging ear place of air-breathing adjustment plate is connected to an iron wire, after making iron wire pass the furnace side face, iron wire is connected to a baffle ring, can push-and-pull adjust air-breathing oral pore in the circle footpath of 50 degree scope, realizes a kind of adjustment mode; Another kind of default being used on the new stove, air-breathing adjustment plate forward direction is added the cover helical spring by spray cartridge periphery be butted on air entry, make its external diameter marginal ridge lip forward, again its 80 degree footpath is set as the positive gear that identical of cloudy dentation engagement side of perforation is established 50 to 60 degree footpaths, make both be engaged on switch valve in 50 to 60 degree, with between the maximum air demand and the minimum inspiratory capacity of fuel oil that are suitable for gas, the front and back of these sun gear central authorities are to the tail end that connects an axostylus axostyle, inserting the rear wall or the U font cross bar that are through at stove and accessory makes it to reverse with clamping before and after the energy, but unlikely moving forward and backward, after the axostylus axostyle that protracts passes antetheca, fix in addition, add at the axostylus axostyle front end again and turn round cover so that do fuel oil and the adjustment of the inspiratory capacity that gas is required by a pole socket.

When being not fuel with gas in addition but above-mentioned shared stove and accessory uses fuel vapor separately, then can exempt regulating the qi flowing in the channels assembly and xenogenesis fuel change-over switch are set, still need make to add between electronic ignition and oil spout gas port the structural improvement of barrier, and after regulating the qi flowing in the channels, needn't do the action of regulating the qi flowing in the channels once more, can make converter nose fire raging fire for a long time.

Extremely shown in Figure 10 as Fig. 1, igniting and air register for a kind of fuel vapor of the utility model and gas change-over switch and shared stove and accessory, include: a gas bucket 1, one fuel drum 2, one shared stove and accessory 3, one switches switch 8 elements such as grade constitutes, after spiral shell is consolidated an air pressure adjuster on the gas bucket 1, be connected to one with a pipeline 11 and switch switch 8, electromagnetism pump 4 is pressed into air by the road in the bucket and overflows through straight pipe in addition, air and fuel oil stir into oil gas, behind the solid air pressure adjuster of fuel drum 2 spiral shells, also be connected to this change-over switch 8 with a pipeline 21, change-over switch 8 is connected to shared stove and accessory 3 with a shared pipeline 31, structure on shared stove and accessory 3, basically the Gas cooker with general is the same, also be to have a burner 32 and an electronic ignition device 33, different is the structure and the air-breathing adjusting device 40 at burner mouth place of setting up external control type that the improvement point is the ignition tip place to the utility model.

Because of the electronic ignition device 33 in the stove and accessory 3 commonly used is specially to form as fuel design with gas, the burning-point of gas is lower, and gas is that the spouting velocity of gas is slow, the big fire state that is useful in very much the external air of powerful jet attraction is lighted, the oil gas burning-point height of opposite fuel oil, and have saturated air, be difficult under brute force is jet, lighting, therefore, general commonly used electric fuel oil bucket all installs the air pressure adjuster additional the flow set of oil gas can be easy to light at the state of moderate heat, promptly can't fire outside the operation of big fire, relevant cost is significantly increased, thereby the price of this kind electric pneumatic oil drum is high, can't be accepted by the consumer, influence utilization rate and the stove and accessory and the fuel drum market of fuel oil, but be not expect that the jet structure by igniter is improved, the utility model at first improves at above-mentioned position, to produce the shared stove and accessory 3 that can be applicable to fuel vapor and gas simultaneously.

As Fig. 2, shown in 3, the release knob 34 of igniter 33 all is the front end face 30 that is installed in stove and accessory 3, when push switch button 34 when left-hand 90 degree reverses, it extends the lightning pin 35 in the stove, when rotating because of the frictional electricity between mutual, make lightning pin 35 produce electric current, produce spark towards relative lightning point plate 36 conductions, wireway 37 and 36 of plates of lightning point leave the space, promptly supply the gas or the fuel oil band of gas to draw air and pass through, gas meeting moment lightning catches fire, but when fuel vapor sprays with strong slightly air pressure, be to light, so slightly before locate to lightning point plate 33 space after a while at puff prot 38, because of brand structure difference, what have establishes conduit, and what have establishes the net groove, promptly adds fixing following wherein a kind of obstacle oil gas thing 39 in conduit or net groove, be respectively: the fire-resistant ferroalloy net of pipe cap shape that (one) one deck is above, as galvanized iron network; (2) the iron net that reverses; (3) cap shape torsionspring; (4) iron wire is twisted into irregular; (5) pipe cap shape porous obstacle body; Come the powerful fuel vapor that flows out of obstacle, so that the mobile mitigation of fuel vapor, just very easily light burning things which may cause a fire disaster with the converter nose place of the state of big fire.

In addition, air-breathing adjusting device 40, as Fig. 2,4, shown in 5, establish one in stove and accessory 3 front end faces 30 and turn round cover 41, this turns round cover 41 sockets one sagittal axostylus axostyle 42, axostylus axostyle 42 is to be articulated in before one holder 43 and back 44 of holders, each holder is for being fixed at stove and accessory 3 front/rear ends, axostylus axostyle 42 leading portions are established a gear 45 that only contains the driving tooth portion 46 of 70 degree scopes by air suction plate 47 places and are engaged in the passive tooth portion 48 of containing 50 to 60 degree scopes on this air suction plate 47, can make the torsion movement that produces between two tooth portions about 50 to 60 degree adjust the space, just can cooperate the required less inspiratory capacity of fuel vapor, air entry 49 can be turned down, the big inspiratory capacity of needs when cooperating with gas in addition, just can to switching adjust, because this suction plate 47 is to fasten in stove spray cartridge 510 peripheries to cover right side, mouth place outer shroud air entry 49 ends that a helical spring 51 bullets are against burner, make air inhale the outer shroud converter nose of burner with gas or fuel oil by the hole on the suction plate of air entry 52, in addition ring air entry 50 to central converter nose be used to burn fuel vapor or gas institute must be more or less the same by an air in the left side, so do not adjust, in order to avoid increase Operating Complexity and raise the cost, just this suction plate is locked in two kinds of required average suction air volumes of fuel and is in harmonious proportion by the firepower of outer shroud again same effect is also arranged.

The gas oven of above-mentioned respective outer side edges family expenses can be shared for fuel vapor, make all energy completing combustion of xenogenesis fuel, must do air-breathing adjustment, install additional with above-mentioned structure and not necessarily can both be suitable for various stove and accessory type bodies or size, various again stove and accessorys were fuel at adopting single kind gas only in the past, its inspiratory capacity several years after new stove is set inspiratory capacity is all no longer adjusted, so, its regulating the qi flowing in the channels plate all is located in the stove, nowadays for adopting the air-breathing demand difference of xenogenesis fuel, must do switching fuel and adjust inspiratory capacity simultaneously, for convenience can both be shared at the old stove and accessory of use, also has the most simple and economical a kind of method, a perforation 55 is bored by ear 54 in former suction plate 53, after wearing knot again one galvanized iron wire 56 passing an aperture of stokehold end face or top side face right side, make galvanized iron wire 56 upper ends be twisted into one and reverse draw ring 57, air entry 49 when making drawing is up hindered into aperture by suction plate 53 and is suitable for fuel vapor at converter nose 3 big fire burns, otherwise air-breathing oral pore is strengthened tension and compression, be suitable for the big fire that burner for gas stove 32 fires completing combustion.Converter nose 3 is all made two mouthfuls with general family, also has flatly or three mouthfuls, can same configuration for it, but when using fuel vapor separately, can exempt above-mentioned regulating the qi flowing in the channels structure and xenogenesis fuel change-over switch.

The change-over switch 8 of xenogenesis fuel, the switching that is used in gas and fuel vapor is used, the fuel oil that uses in can preventing to cook is because of having a power failure or using up the combustion of breaking of individual event fuel, the pipeline that this change-over switch 8 is connect, the oil gas outlet pipe 21 of one termination fuel vapor, the gas outlet pipe 11 of another termination Device in Gas, when twist grip turns to the fuel oil tracheae, fuel vapor is delivered to shared stove and accessory 3 places by switch through shared wireway 31 pipelines, otherwise when switch 8 is diverted to Device in Gas, gas promptly can be delivered to shared stove and accessory 3 places through shared wireway 31 pipelines via change-over switch 8, if only need not to install change-over switch when being used alone fuel vapor.
