1 、所述燃烧器包括包括导热罩体10、燃料导管20以及喷嘴30，燃料由燃料进口进来后经燃料导管20而进入所述喷嘴30中，从喷嘴30出来的燃料经点燃后在所述的腔室11燃烧，之后火从所述出火口12喷出；在该过程中，由于燃料在所述腔室11内的燃烧，能使得所述导热罩体10快速升温，并将热量迅速传导给所述的螺旋盘管21，则燃料导管20内的燃料在流经所述的螺旋盘管21时会被迅速汽化，从而实现造气功能，汽化后的燃料再从所述喷嘴30出来燃烧，这使得燃料的燃烧更加充分，有利于降低环境污染。另外，该燃烧器无需加压罐，其燃料完成汽化燃烧的过程主要是通过一根燃料导管20实现，有利于避免引发爆炸等安全事故。因此，该燃烧器能使燃料更加充分燃烧，热效率高且安全性能好，同时减少了环境污染。 1 The burner includes a heat conducting cover 10, a fuel conduit 20, and a nozzle 30. The fuel enters the fuel inlet 20 and enters the nozzle 30. The fuel from the nozzle 30 is ignited after being ignited. The chamber 11 is burned, and then the fire is ejected from the fire outlet 12; in the process, due to the combustion of the fuel in the chamber 11, the heat conducting cover 10 can be rapidly heated and the heat can be quickly transferred to In the spiral coil 21, the fuel in the fuel conduit 20 is rapidly vaporized when flowing through the spiral coil 21, thereby realizing a gas generating function, and the vaporized fuel is further combusted from the nozzle 30. This makes the combustion of the fuel more complete and helps to reduce environmental pollution. In addition, the burner does not need a pressurized tank, and the process of completing the vaporization combustion of the fuel is mainly realized by a fuel conduit 20, which is beneficial to avoid a safety accident such as an explosion. Therefore, the burner can make the fuel more fully burned, has high thermal efficiency and good safety performance, and at the same time reduces environmental pollution.
2 、所述出火口12设于导热罩体10的前端，喷嘴30设于导热罩体10的后端，有利于实现喷嘴30向出火口12喷出火来。 2 The fire outlet 12 is disposed at the front end of the heat conduction cover 10, and the nozzle 30 is disposed at the rear end of the heat conduction cover 10 to facilitate the discharge of the nozzle 30 to the fire outlet 12.
3 、所述导热罩体10外部还包括联体外罩40，则当导热罩体10在受热升温时，该联体外罩40也不断受热升温，而所述螺旋导管设置在该联体外罩40内，能使燃料的汽化得到进一步的保证，从而使燃料能够更加充分燃烧。 3 The outer cover of the heat conducting cover 10 further includes an outer cover 40. When the heat conducting cover 10 is heated and heated, the outer cover 40 is also heated and heated, and the spiral guide is disposed in the outer cover 40. The vaporization of the fuel can be further ensured, so that the fuel can be more fully burned.
4 、所述喷嘴30包括内环管31与罩壳32，内环管31与罩壳32之间形成内腔33，则上述在螺旋盘管21内经汽化的燃料在通过内环管31的燃料出口会进入所述的内腔33，并在内腔33内因继续受热而实现进一步汽化，即'二次汽化'，二次汽化后的燃料从喷嘴30罩壳32的喷气孔喷出燃烧，这使得燃料能更进一步充分燃烧。 4 The nozzle 30 includes an inner ring tube 31 and a casing 32. The inner chamber 33 is formed between the inner ring tube 31 and the casing 32. Then, the fuel vaporized in the spiral coil 21 is passed through the fuel outlet of the inner ring tube 31. It will enter the inner cavity 33, and further vaporization is realized in the inner cavity 33 by continuing to be heated, that is, 'secondary vaporization', and the secondary vaporized fuel is ejected and burned from the gas injection holes of the nozzle 32 casing 32, which makes The fuel can burn further and further.
5 、设置挡风板50，有利于保证该燃烧器的出火方向；而挡风板50与导热罩体10之间设有间隙，则能够为燃料的燃烧提供适量的风力助燃，使燃料燃烧更加充分。 5 The windshield 50 is provided to ensure the fire direction of the burner; and the gap between the windshield 50 and the heat conducting cover 10 provides an appropriate amount of wind-assisted combustion for fuel combustion, so that the fuel is burned more fully. .
6 、所述的喷嘴30旁侧设有电子打火器80，则能方便点火。 6. The electronic fire extinguisher 80 is disposed on the side of the nozzle 30 to facilitate ignition.
以上所述实施例仅表达了本发明的具体实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。 The above-mentioned embodiments are merely illustrative of specific embodiments of the invention, and the description thereof is not to be construed as limiting the scope of the invention. It should be noted that a number of variations and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention.
