[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1 , which shows the main structure of the adjustable burner assembly given in this example.

[0020] As can be seen from the figure, the adjustable burner assembly has a shell 1, a first cavity 2 is opened inside the shell 1, and a movable block 12 is provided on one side of the shell 1. The movable block 12 is designed with insulating epoxy resin material. The movable block 12 is movably connected to the shell 1 through a circular hole, which enhances the insulation of the movable block 12 and enhances the ignition performance.

[0021] See also Figure 2 and Figure 3 The burner assembly is provided with a first circular hole 5 inside the movable block 12, and an air inlet 3 is provided on one side of the shell 1. Two air inlets 3 are symmetrically arranged about the vertical center line of the shell 1. Fresh air enters the first cavity 2 through the air inlet 3, so that the propane gas can be fully burned. A first air pipe 4 is provided inside the first cavity 2. The first air pipe 4 is detachably connected to the shell 1 through a thread, the connecting block 6 is detachably connected to the shell 1 through a thread, and the second air pipe 10 is detachably connected to the shell 1 through a thread. The height of the first air pipe 4 can be adjusted up and down, which is convenient for adjusting the height of the flame.

[0022] Furthermore, a second cavity 11 is provided inside the first gas pipe 4 in the burner assembly, and a nozzle hole 9 is provided at the upper end of the first gas pipe 4, which is respectively connected to the first cavity 2 and the second cavity 11, and the connecting block 6 is respectively connected to the third cavity 7 and the second cavity 11, so as to better transmit the propane gas. A connecting block 6 is provided at the lower end of the first gas pipe 4, and a groove 8 is provided at the lower end of the connecting block 6. A second gas pipe 10 is provided at the lower end of the groove 8, and a third cavity 7 is provided inside the second gas pipe 10. The second gas pipe 10 is connected to the connecting block 6 by snapping in the groove 8, which is convenient for installation and disassembly.

[0023] The adjustable burner assembly given in this example is configured such that, when in use, the second air pipe 10 is installed on the main pipe, and the shell 1 is respectively installed with the first air pipe 4, the connecting block 6, and the second air pipe 10 through threaded connections. The second air pipe 10 can be snap-connected with the connecting block 6 through the groove 8, and the high-voltage wire is passed through the inside of the first circular hole 5. The first air pipe 4 is rotated to adjust up and down, so as to facilitate adjustment of the flame height.

[0024] On this basis, the propane gas is transported to the interior of the first cavity 2 through the third cavity 7, the connecting block 6, the second cavity 11, and the nozzle hole 9 in sequence, and the transformer is energized to generate 3KV high voltage electricity on the high-voltage line. Figure 4 The middle copper ring A is above the nozzle hole 9. At this time, the high voltage line and Figure 4 Sparks are generated between the protruding parts of the middle copper ring A, thereby igniting the propane gas ejected from the nozzle hole 9. Fresh air enters the interior of the first cavity 2 from the air inlet 3, so that the propane gas can be fully burned, greatly increasing practicality.
