Description

Household liquid fuel stove with evaporation burner

The utility model relates to a kind of domestic burners, particularly a kind of liquid fuel vaporizing burner.

At present the family expenses gasification burner of making fuel with liquid all has the vapourizing unit and the Burning stove hole two-part structure of liquid fuel.With regard to existing vapourizing unit, although concrete shape is varied, its basic structure mostly is tubular structure.The employing straight pipe type that has heating vaporization, the liquid fuel cooking range of being put down in writing as Chinese patent CN90212240; The employing coiled that also has heating vaporization, the fuel gasification stove of being put down in writing as Chinese patent CN90212886.The vaporization mode of this generating tube all is to carry out vaporization combustion in the Burning stove hole of open type.Owing to generating tube is carefully grown, after being heated, liquid fuel do not have enough spaces that it is vaporized rapidly and fully, because the local pressure of heated portion increases, the fuel under high pressure in the pipe is exerted pressure to both direction on the contrary, consequently: feeder sleeve is obstructed because of pressurized makes feed on the one hand; The fuel of vaporization can not sprayed into kitchen range yet on the other hand, and is that pulsating sprays into, and causes kitchen range flame suddenly big or suddenly small, incomplete combustion.

The purpose of this utility model is to provide a kind of liquid fuel that makes fully to vaporize, burn fully at existing problem in the above-mentioned prior art, and the household liquids carburretion stove of flame stabilization.

The solution that realizes the utility model purpose is: the vapourizing unit of the household liquids carburretion stove that is provided is a tubular vaporizer, and Burning stove hole adopts the gas combustion kitchen range with big or small combustion head, and vaporizer is positioned at the top of little combustion head.Set up an air storage chamber between vaporizer and Burning stove hole, the bottom of vaporizer is communicated with the outside liquid fuel reservoir, and the vaporizer top is communicated with air storage chamber, and the outlet of air storage chamber divides two-way to feed large and small combustion head respectively.

Liquid fuel enters vaporizer by the bottom and is heated vaporization, and imports air storage chamber by the top.Because vaporizer is tubular, have certain height, the air accumulation after the vaporization is on vaporizer top, and imports the bigger air storage chamber of volume immediately, so the gasification outlet is unobstructed, can not form retardance, also can not bring the liquid fuel of not vaporizing into air storage chamber.The main effect of air storage chamber is to make the gas that is vaporized can keep one constantly than the pressure stable state.

Above-mentioned air storage chamber outer wall can be connected as a single entity with large-scale combustion head body, the part heat of combustion head can be passed to air storage chamber quickly so on the one hand, makes it to have certain temperature and makes gas in the air storage chamber maintain one more under the stable status; Also can make overall structure compact more on the other hand.

As seen from the above analysis, compare with existing liquid fuel vaporizing burner, advantage of the present utility model is: the vaporization of liquid fuel is rapid, complete, and pressure is more stable, is a kind of pure gas burning, and keeps good fired state.In addition, the utility model has adopted the bullhead gas combustion heads, and by the air storage chamber air feed, so flame size can be regulated easily, does not have what difference from effect and gaseous fuel kitchen range.

Below in conjunction with accompanying drawing content of the present utility model is illustrated.

Fig. 1 is overall structure figure of the present utility model.

Fig. 2 is the another kind of structure chart of the utility model vaporizer.

As shown in Figure 1: the structure of large and small combustion head 1,2 is similar to existing gas combustion heads.Large-scale combustion head 1 is by the fire lid 11 of band fire hole, have the body 12 of circular passage and is communicated with the circular passage of body 12 penetrate pipe 13 compositions.Little combustion head 2 is positioned at the central authorities below of large-scale combustion head 1, is made up of cavity 21 and fire lid 22.Vaporizer 3 is the awl tubular, is positioned at the top of little combustion head 2.Air storage chamber 4 is a ring-type, and the bottom of the body 12 of its upper wall and large-scale combustion head 1 combines as a whole.The top of awl tubular vaporizer 3 is communicated with air storage chamber 4 by pipe 5, and the bottom is communicated with by pipe 6 and liquid-fuel tank (among the figure picture), and the outlet of air storage chamber 4 is divided into two-way, leads up to manage 7 and be communicated with the cavity 21 of combustion head 2; Another road by manage 8 and the pipe 13 of penetrating of valve 9 and large-scale combustion head 1 be communicated with.During the stove and accessory starting, can put a drip pan below, light behind the injection fuel, also can use other igniters or heater that vaporizer 3 is given and be heated to uniform temperature, then liquid fuel be fed vaporizer 3 vaporizations.Gas after the vaporization imports air storage chamber 4 from the top of vaporizer 3 through managing 5, enters little combustion head 2 through managing 7 again, burns at fire hole 23 places.After this, the heating of vaporizer 3 will be finished by little combustion head 2, and the starting process of stove and accessory finishes, and little combustion head will be in fired state always.Because vaporizer 3 is the awl tubular of up/down perforation, so little combustion head 2 has the double action of little baked wheaten cake meal and heating vaporizer concurrently.The thermal radiation effect of air storage chamber 4 during because of the heat conduction that is subjected to large-scale combustion head body 11 and burning has certain temperature, make the gas that enters in the air storage chamber 4 be in more stable gaseous state all the time, and condensation can not occur, thereby guaranteed the stability of combustion flame.When need are used big fire, open valve 9, the gas in the air storage chamber 4 enters and penetrates pipe 13 through managing 8, enters 1 burning of large-scale combustion head then.The big I of firepower by liquid fuel liquid flowing valve or air storage chamber 4 and the valve 9 of penetrating 13 of pipes regulate.

Vaporizer 3 also can be as shown in Figure 2 cylindric, and this moment, little combustion head 2 can stretch into a vaporizer part.

The utility model mainly adopts methyl alcohol to make fuel, also can use other liquid fuels.
