Description

[Detailed description of the invention] (Industrial application field) This invention relates to a kerosene burner for weeding, deicing, sterilization, and insecticide, and particularly to a kerosene burner equipped with an ignition device for starting.

(Prior Art) As shown in FIG. 3, a conventional burner of this type includes a spiral tube 22 whose one end is connected to a kerosene fuel tank 21, and whose other end is located approximately at the axial center of the spiral tube 22. When in use, the inside of the tank is sufficiently pressurized by a pump 24 installed in the tank, and then the spiral tube 22 is heated, and the injection lever 25 is operated to inject fuel. When the valve 26 is opened and the nozzle 23 is ignited, gaseous kerosene becomes a flame and is vigorously injected. During use, the kerosene in the helical tube 22 is heated by the flame from the nozzle and vaporized, so the helical tube 22 only needs to be heated at the time of startup. In the figure, 27 is a flame hood, 28 is a protective cover provided to cover the combustion part of the nozzle, and 29 is a shoulder belt.

(Problem to be solved by the invention) However, in the device with the above configuration, at the time of startup,
The spiral tube 2 is used to vaporize the kerosene in the spiral tube 22.
Conventionally, as shown in Fig. 4, heating solid fuel 30 is placed on flat ground or a concrete floor, the burner part is placed vertically on top of heating solid fuel 30, and then the heating solid fuel 30 is heated. 2~ in the state of
This is done by heating the spiral tube 22 in a burner for 3 minutes. However, this heating requires a long time, especially in cold regions, and there are problems such as the need to carry solid fuel for heating. If solid fuel is not available, it is possible to heat an empty can by putting kerosene in a rag or newspaper and lighting it, but in either case, the appearance of the product may deteriorate due to the soot generated. There was a problem that it stained the area and made it unsightly.

Therefore, the object of this invention is to provide a kerosene burner that solves the problems of the prior art.

(Means for Solving the Problems) In order to solve the above-mentioned problems, this invention has one end connected to the kerosene fuel tank and the other end of the spiral pipe arranged in a direction substantially toward the axial center of the spiral pipe. A ring having a plurality of orifices opening in the diametrical direction or inward direction near the opening at the tip of the protective cover of the combustion part of a burner that is connected to a nozzle and burns kerosene while vaporizing it in a spiral tube. This kerosene burner is characterized in that it is provided with a shaped auxiliary burner, and an LPG gas cylinder can be attached to the auxiliary burner.

(Function) As described above, this device introduces LPG gas into the auxiliary burner at the time of startup by attaching a portable LPG gas cylinder instead of solid fuel to the auxiliary burner installed near the opening at the tip of the burner's protective cover. By igniting this, the spiral tube located near the tip of the burner is heated and the kerosene inside the spiral tube is vaporized, making it easy to ignite the nozzle, and after igniting the pressurized gas The kerosene becomes a flame and is sprayed. In this case, the multiple orifices installed in the auxiliary burner are oriented diametrically or inwardly, so the air near the tip of the protective cover is sucked in and the LPG gas flame reaches deep inside the protective cover. The spiral tube can be heated efficiently and vaporize kerosene quickly. In addition, in this case, a portable mini-cylinder can be used to supply LPG gas, making it easier to carry than solid fuel, and it is also more practical as it does not stain the burner exterior with soot, etc. .

(Embodiment) FIG. 1 is a sectional view showing the main parts of an embodiment of the kerosene burner of the present invention. In the figure 1
is a spiral tube, 2 is a nozzle, 3 is a valve (a part of which is shown in the figure), 4 is a hood, 5 is a protective cover,
Although not shown in the figure, other components such as a kerosene fuel tank, pump, injection lever, etc. are exactly the same as a conventional kerosene burner. In the present invention, a ring-shaped auxiliary burner 6 having a plurality of orifices 7 opening in the diametrical or inward direction is provided near the tip of the protective cover 5, and an LPG cylinder ( (not shown)
A mounting opening 8 is provided so that the device can be mounted. In addition, 9 in the figure is a fixing plate of the hood 4, and 1
0 indicates a fixing plate for the nozzle 2, and 11 indicates a baffle plate provided to protect the joint 12 of the fuel pipe from flames. In this way, the ring-shaped auxiliary burner 6 provided near the tip of the burner protective cover 5 burns LPG gas from a portable LPG gas cylinder instead of solid fuel.
When starting, the kerosene in the spiral tube 1 is vaporized.

In this embodiment, the ring-shaped auxiliary burner 6 is attached directly to the inner wall of the tip of the protective cover 5, but as shown in FIG. It may also be made to fit.

(Effects of the invention) As explained above, the kerosene burner of the present invention has an auxiliary burner that burns LPG gas internally disposed close to the helical tube near the opening at the tip of the protective cover. is formed into a ring shape, and LPG gas flame is injected from multiple orifices that open in the diametrical direction or inward direction, so the heating efficiency for the spiral tube is high, and the time to vaporize kerosene during startup is shortened. In addition, it is easier to ignite than when using solid fuel, and the appearance of the product can be kept beautiful without contaminating it.
