[0024] Example

[0025] Reference Figure 1 The utility model proposes a liquid fuel burner with a side air intake and inner bottom air intake structure, comprising: a base 10, an inner tank 20, a fire cover assembly 30, an ignition assembly 40, a blower 50 and a fuel nozzle 60;

[0026] The base 10 is a cylindrical structure, and is divided into an ignition chamber 11 and a blast chamber 12 by a partition 13; the blast chamber 12 is located below the ignition chamber 11, and an embedding hole 14 is opened above the ignition chamber 11, and the inner tank 20 is detachably placed on the embedding hole 14; the partition 13 is provided with an air supply hole 15 connecting the ignition chamber 11 and the blast chamber 12;

[0027] The fire cover assembly 30 is detachably placed on the inner container 20. The outer wall of the fire cover assembly 30 and the inner wall of the inner container 20 are surrounded by a primary combustion chamber 70. The inner wall of the fire cover assembly 30 is surrounded by a secondary combustion chamber 80.

[0028] A blast pipe 51 connected to the blower 50 is provided on one side of the blast chamber 12 ; the fuel nozzle 60 passes through the air supply hole 15 and extends into the ignition chamber 11 ; and the ignition needle of the ignition assembly 40 extends toward the fuel nozzle 60 .

[0029] In the utility model, the blast chamber 12 is connected to the blower 50 through the blast pipe 51. The blower 50 can blow sufficient air into the blast chamber 12, and blow air from bottom to top through the air supply hole 15 of the partition 13, and mix with the liquid fuel sprayed by the fuel nozzle 60, ignite in the ignition chamber 11, and then burn in the primary combustion chamber 70, and send it to the secondary combustion chamber 80 for further combustion. In the utility model, the inner tank 20, the fire cover assembly 30 and the base 10 can be detachably installed, which is convenient for installation, disassembly and cleaning; the ignition chamber 11 and the blast chamber 12 are arranged in staggered layers from top to bottom, so that air is supplied and transported from bottom to top, and the formed mixed gas passes through the ignition chamber 11, the primary combustion chamber 70 and the secondary combustion chamber 80 from bottom to top for combustion, effectively avoiding the flashback combustion phenomenon, and fully contacting and mixing with the air, reducing the influence of the flash point of different oil types, and for different liquid fuel oil types, such as white oil, effective ignition and sufficient combustion effect can be achieved.

[0030] In this embodiment, the fuel nozzle 60 includes a nozzle column 61 and a nozzle head 62. The nozzle head 62 is detachably locked to the nozzle column 61. The nozzle column 61 is fixed to the base 10 and connected to the high-pressure oil pump. The nozzle column 61 is screwed to a fixing nut at the bottom of the base 10.

When there is no flame above the fire cover assembly 30, the flameout protection probe 90 can be linked to the high-pressure oil pump to stop working, or the high-pressure oil pump can be controlled to stop working by the controller to prevent the liquid fuel from being continuously sprayed.

[0034] In this embodiment, the inner container 20 is provided with a plurality of primary fire holes 21 for connecting the ignition chamber 11 and the primary combustion chamber 70 .

[0035] In this embodiment, the fire cover assembly 30 includes a fire cover seat 31 and a fire cover cap 32; the fire cover cap 32 is covered on the fire cover seat 31 and surrounds the secondary combustion chamber 80; the fire cover seat 31 is provided with a plurality of secondary fire holes 33 for connecting the primary combustion chamber 70 and the secondary combustion chamber 80; the fire cover cap 32 is provided with a plurality of tertiary fire holes 34. The fire cover cap 32 is separately provided with the fire cover seat 31, and by changing the arrangement structure of the tertiary fire holes 34, different combustion flame effects such as direct injection, rotary fire or multi-head fire can be formed.
