[0033] First flange plate 38 and second flange plate 39 are connected by bolt.

[0034] Embodiment two

[0035] Please refer to Figures 5-6 And on the basis of embodiment one, further obtain filter mechanism 4.

[0036] The filtering mechanism 4 comprises a fixed ring 41 fixedly connected to the surface of the air inlet pipe 33 close to the top end, L plates 42 fixedly connected symmetrically on the front and back surfaces of the fixed ring 41, slide rods 43 provided on the side of the L plates 42 away from the air inlet pipe 33, pull plates 44 fixedly connected to the other ends of the slide rods 43, arc-shaped blocks 47 fixedly connected to the other ends of the slide rods 43, fixed discs 45 fixedly connected to the ends of the slide rods 43 close to the air inlet pipe 33, springs 46 sleeved on the surfaces of the slide rods 43 between the L plates 42 and the fixed discs 45, and limiting rings 48 fixedly connected to the inner walls of the air inlet pipes 33 close to the top ends, and circular filter screens 49 slidingly connected to the inner walls of the air inlet pipes 33.

[0037] The side of the L plate 42 away from the air inlet pipe 33 is provided with a hole matched with the slide rod 43, and the surface of the slide rod 43 penetrates the hole and is slidingly connected to the hole left and right.

[0038] One end of the spring 46 is fixedly connected to the side of the L plate 42 close to the air inlet pipe 33, and the other end of the spring 46 is fixedly connected to the side of the fixed disc 45 away from the air inlet pipe 33.

[0039] In actual operation, when the device is used, the air pump 32 is started, the air inlet end of the air pump 32 inhales external air through the air inlet pipe 33, and the air outlet end outputs compressed air through the air outlet pipe 34. The air pump 32 provides power for the air to overcome the resistance of the pipeline and quickly and effectively enter the burner body 2 to participate in the combustion process. In the burner body 2, the Venturi tube 36 is arranged in the fixed block 35. The structural feature of the Venturi tube 36 is that the pipe diameter of the middle part is contracted. When the air output by the air outlet pipe 34 passes through the Venturi tube 36, according to the Venturi effect, the flow rate of the air increases in the contraction section, and the pressure decreases. The connecting air pipe 37 connected to the surface of the Venturi tube 36 close to the right end. Due to the negative pressure in the Venturi tube 36, the fuel from the air outlet end is sucked in and fully mixed with the high-speed flowing air. This mixing method utilizes the characteristics of the Venturi tube 36, so that the air and the fuel can be efficiently mixed before entering the combustion chamber, which creates favorable conditions for subsequent full combustion. The air outlet pipe 34 is connected to the second flange plate 39 of the connecting air pipe 37 through the first flange plate 38, and the two are fastened by bolts. This flange connection method is not only convenient for installation and disassembly, but also facilitates the maintenance and repair of the burner, and can ensure the sealing of the air path to prevent air and fuel leakage and ensure the stability and safety of the mixing process.

[0040] The fixed ring 41 is fixed on the surface of the air inlet pipe 33, and the symmetrically connected L plates 42 provide support structure for the circular filter screen 49. The circular filter screen 49 is connected to the inner wall of the air inlet pipe 33 in a sliding manner. When external air passes through the air inlet pipe 33, the circular filter screen 49 can intercept dust, impurities and other particulate matters in the air, so as to filter the air entering the burner, ensure the cleanliness of the air entering the burner, and avoid the negative impact of impurities on the combustion effect. When the circular filter screen 49 needs to be cleaned or replaced, the pull plate 44 is pulled, the pull plate 44 drives the sliding rod 43 to slide in the hole of the L plate 42 away from the air inlet pipe 33, the arc-shaped block 47 connected to the other end of the sliding rod 43 synchronously slides in the groove on the surface of the air inlet pipe 33, so that the circular filter screen 49 can be pulled out of the air inlet pipe 33. The spring 46 is sleeved on the sliding rod 43 between the L plate 42 and the fixed disc 45. When the circular filter screen 49 is cleaned or replaced, the pull plate 44 is loosened, the spring 46 is pushed to drive the fixed disc 45 to reset the sliding rod 43 under the action of the spring force, so that the circular filter screen 49 returns to the working position in the air inlet pipe 33, and is tightly attached to the inner wall of the air inlet pipe 33, so as to ensure the filtering effect. The limiting ring 48 prevents the circular filter screen 49 from sliding excessively in the air inlet pipe 33, and ensures that the circular filter screen 49 plays a filtering role in the appropriate position.

[0041] It should be noted that the relational terms herein such as first and second and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any such actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element preceded by "comprises a" does not, without more constraints, foreclose the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.
