blowtorch

The present invention relates to a burner, and more particularly to a burner that can be installed in a gas canister and electronically ignited.

Referring to Figures 1 and 2, there is a novel patent No. M292672, which discloses a burner 1 which is mountable for a gas canister 2 and which comprises: a bracket 11 for the gas canister 2 to be mounted, and A fuel supply device 12, an ignition device 13, mounted on the bracket 11. The bracket 11 has a suspended assembly portion 111.

The fuel supply device 12 includes a fuel supply seat 121 that is mounted on the assembly portion 111 of the bracket 11 and has a fuel passage (not shown), and an adjustment of the gas flow rate mounted on the fuel supply seat 121. A valve 122, a sleeve 123 mounted at the front end of the fuel supply seat 121, and a fuel injection head 124 and a pilot nozzle 125 mounted on the fuel supply seat 121 and communicating with the fuel passage. The sleeve 123 has a tube wall 127 defining a fire-spraying space 126 having a plurality of combustion-supporting holes 128 and a downwardly facing perforation 129, and the igniter 125 has a horizontal flow path defining a level The ring wall of 120.

The ignition device 13 includes a mounting on the bracket 11 An ignition control button 131 on the assembly portion 111, an ignition terminal 132 disposed under the wall 127 of the sleeve 123, and an electric wire 133 electrically connecting the ignition terminal 132 and the ignition knob 131, the ignition terminal 132 has a firing end 134 that penetrates the perforation 129 and is adjacent the forward end of the pilothead 125. When the regulator valve 122 is used to open and adjust the flow rate of the gas, and then the ignition control button 131 of the ignition device 13 is pressed, an arc is generated at the ignition end 134 of the ignition terminal 132 to ignite the ignition nozzle 125. The gas that flows out simultaneously ignites the gas ejected by the fuel nozzle 124.

Although the conventional burner 1 has the function of electronic ignition, it is prone to problems such as poor ignition efficiency and inconvenient installation during use and manufacture. The main reason for the aforementioned deficiency is that the specific gravity of the gas is heavier than that of the air, so in the normal state, the gas flowing horizontally from the flow path 120 of the priming nozzle 125 is easily settled downward, but the ignition end 134 of the ignition terminal 132 that generates the arc is generated. Since it is located substantially at the leading edge of the flow path 120, the position and height of the ignition terminal 132 at the time of mounting are less likely to ignite the gas sent from the igniter 125, resulting in an unsatisfactory ignition efficiency. In addition, the firing end 134 of the ignition terminal 132 of the conventional burner 1 is bent at 90 degrees and protrudes into the firing space 126 of the sleeve 123. In the detection process before leaving the factory, if the ignition efficiency is found to be poor, it must be in the tube. Adjusting the position and height of the ignition end 134 of the ignition terminal 132 in the small fire-breathing space 126 is not only inconvenient to adjust, but also has poor accuracy after adjustment, which inevitably reduces the ignition efficiency. Further, in the case where the support lamp wire 133 is lacking in support, it is easy to lean against the high-temperature fuel supply seat 121, so that there is a fear that it is blown at a high temperature.

The purpose of the present invention is to provide a burner that can improve ignition efficiency and assembly convenience.

The blow lamp of the present invention comprises a bracket, and a fuel supply device mounted on the bracket, an ignition device, the fuel supply device comprising: a fuel supply seat mounted on the bracket and having a fuel passage, and a fuel supply seat mounted on the bracket a sleeve on the fuel supply seat, and a priming nozzle mounted on the fuel supply seat, the sleeve having a wall defining a squib space that engages the fuel passage, the tube wall having a communication space with the blast space a perforation having a ring wall defining a flow passage and a retaining wall closing the front end of the flow passage, the annular wall having at least one fuel overflow adjacent to and facing the perforation of the sleeve, and the The ignition device includes an ignition terminal mounted on the fuel supply device, the ignition terminal having a firing end adjacent to the perforation of the sleeve and the fuel overflow of the pilot head.

The present invention has the beneficial effect that the present invention can improve ignition since the front end of the flow passage of the ignition nozzle is closed and a fuel overflow hole is formed on the ring wall for allowing the fuel to sink and adjacent to the ignition end of the ignition terminal. s efficiency.

The installation department 411 and a fuel passage 413 of the discharge portion 412 having a main outlet 414 on a central axis of the sleeve 42 and a pilot outlet 415 located below the main outlet 414. The fuel injection head 44 is mounted on the main outlet 414 of the fuel passage 413, and the pilot nozzle 45 is mounted on the pilot outlet 415 of the fuel passage 413. Since the configurations of the fuel supply seat 41, the regulating valve 43, and the fuel injection head 44 are known in the art, they will not be described.

In this embodiment, the sleeve 42 is made of a metal material and is successively mounted on the discharge portion 412 of the fuel supply seat 41. The sleeve 42 has a pipe wall 422 defining a fire-spraying space 421. The 422 has a plurality of combustion holes 423 extending therethrough for air ingress, and a downwardly facing perforation 424. The igniter 45 is an inner hollow tubular structure and has a ring wall 452 defining a flow passage 451, and a retaining wall 453 closing the front of the flow passage 451. The annular wall 452 has a plurality of annular arrays and A fuel overflow 454 that communicates with the flow passage 451 adjacent the leading edge of the bore 424 of the sleeve 42. In design, the fuel overflows 454 are only one and toward the perforations 424 to achieve the intended purpose, that is, the number of the fuel overflow holes 454 of the present invention is not limited to those disclosed in the embodiments.

The ignition device 5 of the present embodiment includes an ignition terminal 51, a bracket 52 for mounting the ignition terminal 51 at the lower edge of the sleeve 42, a mounting portion at the lower edge of the sleeve 42 and protecting the ignition terminal 51.

The ignition terminal 51 has a firing end 511 located below the perforation 424 of the sleeve 42 and adjacent to the fuel spill 454 of the pilot head 45, and the spring seat 56 has a length of wire secured around the outer circumference of the wire 55. The segment 561 and the two extensions 562 are respectively mounted on the sleeve 42 and the assembly portion 321 of the strut 32 by the screws 57. Further, one of the extensions 562 has a support portion 563 that extends the wire securing segment 561 away from the fuel supply device 4.

In this embodiment, after the burner is assembled, the ignition end 511 of the ignition terminal 51 is located below the firing space 421 of the sleeve 42 and is protected by the protective cover 53 , and the ignition nozzle 45 of the fuel supply device 4 The fuel overflow 454 is adjacent to the through hole 424 of the sleeve 42 and the firing end 511 of the ignition terminal 51. When the regulating valve 43 is opened to allow the gas in the gas canister 2 to flow to the fuel passage 413, and the gas flows to the fuel injection head 44 and the igniter 45, respectively, the gas flowing to the priming nozzle 45 is blocked by the blocking wall 453. Under the dual influence of the gas specific gravity being greater than the air, it will naturally settle down and flow out of the fuel overflow 454 adjacent to the perforations 424 of the sleeve 42. Since the ignition end 511 of the ignition terminal 51 of the ignition device 5 is located below the fuel overflow holes 454, when the user activates the ignition knob 54, the ignition terminal 511 of the ignition terminal 51 generates an arc. The settled gas can be quickly ignited, thereby achieving the purpose of easy and rapid ignition.

In terms of manufacturing, the ignition terminal 51 of the ignition device 5 of the embodiment is hung under the tube wall 422 of the sleeve 42 by the bracket 52. The ignition end 511 of the ignition terminal 51 is also located below the firing space 421 of the sleeve 42. Therefore, during the process of detecting and repairing the burner, the arc generated by the ignition terminal 51 and the ignition head 45 can be easily observed. The relationship between the fuel overflow holes 454, and then the mounting position of the ignition terminal 51 is adjusted, and then the protective cover 53 is mounted. Since the ignition end 511 of the ignition terminal 51 is located below the sleeve 42, the adjustment is made. When the position and height of the igniter 45 are adjusted, it can be adjusted outside the blasting space 421 of the sleeve 42, thereby achieving the purpose of convenient installation and maintenance.

As for the purpose of providing the fuel overflow holes 454 on the igniter 45 in the present embodiment, in addition to facilitating the gas sinking and the generated arc, another advantage is that the igniter 45 is conveniently installed, that is, the squib is installed. When the nozzle 45 is used, one of the fuel overflow holes 454 will face downward and adjacent to the through hole 424 of the sleeve 42 regardless of the installation angle thereof, but the embodiment does not have a plurality of fuel overflow holes 454 in manufacturing. As necessary. In addition, the spring seat 56 installed in this embodiment can not only dispose the electric wire 55 from the fuel supply seat 41, but also avoid the high temperature generated by the sleeve 42 during the fire-breathing process from being transmitted to the fuel supply seat 41, thereby causing the electric wire 55. In addition to the firing, the engagement of the extensions 562 of the spring seats 56 with the screws 57 can also create a grounding effect that allows the electrons of the arc to be released.

However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification, All remain within the scope of this new patent.
