This case relates to a gas burner, especially a gas burner with the function of adjusting the combustion angle.

Pressing fire is indispensable in our daily life. With it, we can get cooked food, lighting, and even forging, welding, welding and other burning operations of metal objects. Take canned gas as an example, because it uses liquid gas, so whether it is filled with a lighter or fitted with the ring of a portable gas stove, in order to ignite items or cook food, it has its convenience. At the same time, the canned gas It is extremely convenient in carrying and storage. Therefore, today, there are irreplaceable role plays.

Due to the convenience of canned gas, there are two types of gas burning tools in the workshop for users to choose.

For example, a screw passes through the right casing 12 and is locked to the left casing 11. Wherein the fixed casing 1 is provided with the gas storage barrel 2, the gas storage barrel 2 is used to store liquid gas, and a gas filling nozzle (not shown in the prior art) is known at the bottom for replenishing liquid Gas (fuel). The top of the gas storage cylinder 2 is provided for installing the gas outlet device 3.

Furthermore, one of the left casing 11 and the right casing 12 has a rod hole 111 and at least one insertion hole 112 laterally defined at the top of the left casing 11.

The air outlet device 3 is a conventional one, and includes an air outlet valve 31 installed on the top of the gas tank 2, an upstream end sleeved on the air outlet valve 31 and passing through a slot formed on the top of the fixed casing 1 An air supply hose 32 of 113, an air injection nozzle 33 provided at a downstream end of the air supply hose 32, and an L-shaped air outlet plate 34 sleeved at one end of the air outlet valve 31. The air outlet plate 34 is pivotally connected to the fixed housing 1, one end is sleeved with the air outlet valve 31, and the other end is abutted with a pressing member 41 of the electronic ignition device 4.

Therefore, when the other end of the air outlet plate 34 is pressed by the pressing member 41, the air outlet plate 34 is leveraged to pull up the air outlet valve 31 to form an open pattern to make the gas reservoir After the gas in the liquid 2 is gasified, it enters the gas delivery hose 32 from the gas outlet valve 31 and is rapidly ejected by the gas injection nozzle 33 to enter the combustion device 6.

In one embodiment, the through slot 113 is disposed on one side of the rod hole 111 and the at least one insertion hole 112.

The gas outlet device 3 further includes an adjustment member 35, which includes a sleeve ring 351 laterally sleeved on the gas outlet valve 31, and an adjustment rod 352 extending laterally from the sleeve ring 351. The adjusting rod 352 can extend out of the fixed casing 1. Therefore, the adjustment lever 352 is turned to rotate the gas outlet valve 31 along with the collar 351, thereby adjusting the gas outlet volume.

The ignition device 4 includes the aforementioned pressing member 41 and a piezoelectric device 42. A pair of side walls of the pressing member 41 and a pair of inner walls of the fixed housing 1 are provided with a pair of sliding rails 411 and a pair of rail grooves 114 for sliding the pair of sliding rails 411, The pressing member 41 is slid longitudinally in the pair of rail grooves 114 by the pair of slide rails 411 to press the piezoelectric device 42 installed between the pair of inner walls. The bottom of the piezoelectric device 42 is in contact with a pair of baffles 115 of the pair of inner walls of the fixed housing 1 to make the piezoelectric device 42 has a conventional pressing and rebounding function. It has a conductive wire 421 and a return wire 422. The conductive wire 421 and the return wire 422 pass through the slot 113 and extend into the combustion device 6 together.

Please refer to FIGS. 2 and 3 again. The inner side of the pressing member 41 corresponds to the position of the air pressure plate 34 and extends a pressure handle 412 above the air pressure plate 34, and the opposite of the pressure handle 412, that is, the pressing A button 413 protrudes from the outside of the member 41. The button 413 protrudes from a button slot 14 opened in the fixed housing 1, so that the button 413 is exposed outside the fixed housing 1 as shown in FIG. 1.

In order to prevent misuse by children, the pressing member 41 further includes a safety switch 43, the safety switch 43 is slidably installed in a predetermined accommodating groove 414 on the top of the pressing member 41, the outer side of the safety switch 43 A protruding button 431 protruding out of a key hole 15 formed in the fixed casing 1 is provided, and a pair of wings 432 and a A pair of wing grooves 415 for sliding the pair of fins 432, and an inner side of the safety switch 43 is provided with a spring tenon 433 (shown in FIG. 7a) for one end of an auxiliary spring 44 sleeved, and the auxiliary spring 44 The other end is in contact with a rear wall 416 opposite to the accommodating slot 414, so that the safety switch 43 can elastically telescopically slide in the accommodating slot 414 to form the locking or unlocking of the safety switch 43 Type.

Therefore, when the safety switch 43 is not operated, the convex button 431 longitudinally abuts the key hole 15, so that the button 413 cannot be pressed longitudinally, resulting in a locked and unpressable type.

If the pressing member 41 is to be unlocked, that is, the convex button 431 can be smoothly retracted into the key hole 15 to release the locking mode, so the outer side of the convex button 431 has an arc end 431a, and A guiding arc surface 151 is connected to the lower inner side of the key hole 15. When the knob 431 is pressed by the user's finger, it moves inward and compresses the auxiliary spring 44 so that the arc end 431a enters the key hole 15 and is located above the guide arc surface 151 (shown Figure 7b) to form an unlocked pattern.

Next, the user's finger presses the button 413 longitudinally, so that during the longitudinal displacement of the button 413 in the button groove 14, the arc end 431 a moves down along the guide arc surface 151, and the pressing member 41 Then, the piezoelectric device 42 is pressed synchronously, so that the pressing handle 412 touches one end of the air pressure plate 34 during displacement, and the other end of the air pressure plate 34 pulls up the air outlet valve 31 (shown in FIG. 7c) , The gas passes through the gas hose 32 and is ejected by the gas outlet 33 to enter the combustion device 6, and the current generated by the piezoelectric 42 is transmitted by the conductive wire 421, and in the Combustion device 6 An internal flame nozzle 63 generates a spark to burn the mixed gas, and then conducts the current back to the piezoelectric device 42 through a return wire 422 to form a current loop.
