DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a vaporizer for heating and vaporizing a liquid such as kerosene and ejecting the same.

[0002]

2. Description of the Related Art Conventionally, this type of vaporizer has been widely used for, for example, a petroleum fan heater, and as shown in FIG.
Body 53 for accommodating movable piece 52 connected to
4. An ejection pipe 56 having an ejection port 55 which is opened and closed by a valve rod 51 at the tip is welded and connected in sequence to form a vaporization cylinder 57.
The vaporized gas flowing into the ejection pipe 56 from the
There is known a configuration in which the gas is ejected more.

[0003]

By the way, the vaporizer of the above construction has poor workability as a whole because of the large number of welding points and the need to carefully work to prevent gas leakage due to welding defects. there were.

Further, when the ejection port 55 is open, the valve rod 51 hangs down as shown in FIG. 4, so that the space in the ejection pipe 56 is biased and flows into the communication port 58 through the communication port 58. It will affect the vaporized gas. Therefore, for example, the valve rod 5
1, a groove is formed at an appropriate position, and an appropriate ring body is fitted into the groove to prevent dripping. However, in this case, the number of steps increases and the ring body gradually moves due to the frequent advance and retreat of the valve rod 51. Inconveniences, such as deformation to the shape, occur. An object of the present invention is to provide a vaporizer that solves the above-mentioned problems.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a vaporizer in which an outlet is opened and closed by sliding of a movable piece connected to a valve rod, and a cylindrical portion for accommodating the movable piece and a small diameter portion. And a solid polygonal section midway between the cylindrical part and the small diameter part.
The fixed part is integrally formed by deep drawing and after the deep drawing
The valve rod is supported by punching out the end of the small diameter section
An ejection pad that forms a projection and has an ejection port at the small diameter part
The present invention relates to a vaporizer in which IPs are connected and connected .

[0006]

According to the above construction, the cylindrical portion and the jet pipe are joined by one welding, so that the number of welding times is reduced.
And vaporization equipment by the fixing part formed in polygonal cross section.
The assembly of the device can be performed easily and without variation. Furthermore, a projection can be formed only by punching out the bottom wall surface of the small diameter portion after the deep drawing, and this projection prevents the valve rod from sagging and has sufficient durability against frequent movements.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below by applying it to an oil combustor. In FIG. 1, reference numeral 1 denotes a cylindrical body, and a cylindrical portion 2 and a small-diameter portion 3 are integrally formed by deep drawing. 4
Are projections, and a plurality of projections are formed by punching out the bottom wall surface of the small-diameter portion 3 after deep drawing, as shown in FIG.
Reference numeral 5 denotes an ejection pipe having an ejection port 6 at the tip, and the opposite side of the ejection port 6 is joined to the small diameter portion 3 by welding. As described above, the vaporizer of the present example has a smaller number of weldings than the conventional product, so that the workability is good and gas leakage hardly occurs.

Reference numeral 7 denotes a movable piece accommodated in the cylindrical portion 2.
Here, the movable piece 7 is constantly pressed in the direction of the jet port 6 by an elastic body 9 interposed between the movable piece 7 and the fixed piece 8. Reference numeral 10 denotes a valve rod, on one of which a needle valve 11 for opening and closing the jet port 6 is formed.
The other is connected to the movable piece 7. Reference numeral 12 denotes a vaporizing cylinder provided with a heater 13. The vaporizing cylinder 12 communicates with the ejection pipe 5 through a communication port 14 and is connected to a pump 16 through an oil supply pipe 15. 17 is a solenoid,
18 is a burner.

In the above configuration, the vaporizing cylinder 12 is heated by the heat generated by the heater 13, and when the vaporizing cylinder 12 rises to a temperature at which kerosene can be vaporized, the pump 16 starts. As a result, the kerosene is pressure-fed into the vaporization cylinder 12, and the kerosene is heated and vaporized to become a vaporized gas, and flows into the ejection pipe 5 through the communication port 14. The solenoid 17 is energized before or after the start of the pump 16, and at the same time, the movable piece 7 slides toward the fixed piece 8 and the needle valve 11 separates from the ejection port 6. It gushes to the burner 18 and burns.

Incidentally, the valve rod 10 is supported by the projection 4 and does not drop. Therefore, since the space in the ejection pipe 5 is not biased, the vaporized gas from the vaporization cylinder 12 can smoothly flow into the ejection pipe 5, and is sequentially ejected from the ejection port 6, so that the burner 18 performs stable combustion. . Further, since the projection 4 has durability and does not deform at all even if the valve rod 10 moves frequently, the performance of the combustor can be maintained for many years.

Next, the vaporizing apparatus of this embodiment uses a fixed portion 1 having a hexagonal cross section between the cylindrical portion 2 and the small-diameter portion 3 during deep drawing.
9 are formed. Therefore, the mounting angle of the vaporizing cylinder 12 can be kept constant by, for example, screwing an appropriate holding member 20 meshing with the fixing portion 19 to the cover 21, whereby the assembling of the vaporizing device is easy, the dispersion is small, and the vaporized gas is small. It is also possible to stabilize the ejection amount.

[0012]

Vaporizer street present invention described above, according to the present invention is integrally molded by deep drawing a cylindrical portion and a small diameter portion and the fixing portion, since the joining communicates ejection pipe having an ejection port to the small diameter portion, the prior art the good workability less weld times than, I with little even occurrence of defects such as causing gas leakage
And the fixing part has a polygonal cross section,
Assembly can be performed easily and without variation . Further, the projections have sufficient durability and prevent the valve rod from sagging so that the vaporized gas flows smoothly, so that there is an effect that the performance of the combustor can be maintained for many years.
