[0004] Although the above-mentioned prior art pulls the handle to drive the filter plate to slide on the air inlet, and the filter plate can filter out particulate impurities in the air when the air enters the air inlet, in actual use, when the filter plate is removed, its air inlet channel is connected to the outside, and dust or other particulate impurities in the air may enter the inside of the channel, resulting in particulate impurities in the air that are not filtered by the filter plate during the next use may enter the interior of the burner, which has poor practicality and poor dust prevention effect. In view of this, we propose an oxygen-enriched burner to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

A cavity 501 is provided inside the left fixing block 5, and a driving component is provided inside the cavity 501. The upper surface of the air inlet duct 4 is provided with two transverse grooves 21, and a sealing component is provided inside the transverse groove 21. When the staff needs to disassemble and clean the filter plate 8, the driving component is first used to drive the rotation of the bidirectional threaded rod 10. The rotation of the bidirectional threaded rod 10 can drive the two first L-shaped connecting blocks 11 to slide inside the guide groove 9. The movement of the second L-shaped connecting block 12 can be driven by the first L-shaped connecting block 11. At this time, the second L-shaped connecting block 12 will be inside the sliding groove 13. The second L-shaped connecting block 12 will slide out of the inner part of the card slot 14, thereby no longer fixing the filter plate 8. At the same time, the movement of the driving assembly will also synchronously drive the rotation of the shaft body 601, and the rotation of the shaft body 601 will drive the rotation of the sealing plate 6, and finally the sealing plate 6 will seal the front end of the air inlet duct 4 while releasing the lock of the filter plate 8. The above structure avoids as much as possible the situation that external air will enter the air inlet duct 4 after the filter plate 8 is disassembled, thereby avoiding the situation that unfiltered air is subsequently inhaled, ensuring the subsequent combustion efficiency and effect, improving the sufficiency of combustion, and further improving the practicality of the device.

[0029] Furthermore, the driving component includes a winding roller 15, which is rotatably connected to the inside of the cavity 501. The winding roller 15 rotates and passes through the inside of the guide groove 9 and is fixedly connected to the bidirectional threaded rod 10. One end of the winding roller 15 located inside the cavity 501 is fixedly sleeved with a partition plate 16, and a pull rope 1601 is provided between the two partition plates 16. The pull rope 1601 is wound around the outside of the winding roller 15, and the other end of the pull rope 1601 is fixedly connected to the shaft 601. The winding roller 15 rotates and passes through the inside of the fixed block 5. A locking component is provided on the outside of the winding roller 15. The pull rope 1601 can be wound up by rotating the winding roller 15, and the rotation of the shaft 601 can be achieved by winding up the pull rope 1601, and then the rotation of the sealing plate 6 is achieved, thereby completing the synchronous movement of the second L-shaped connecting block 12 and the sealing plate 6.

[0030] Furthermore, the locking assembly includes a handle 17, which is slidably sleeved on the outer surface of the winding roller 15 through the cooperation of the card block and the card slot. A first spring 18 is fixedly connected between the winding roller 15 and the inner wall of the sliding groove inside the handle 17. A hemisphere 19 is fixedly connected to the side surface of the handle 17 facing the fixed block 5. A ball groove 1901 is provided on the surface of the fixed block 5, and the hemisphere 19 is adapted to the ball groove 1901. When the staff needs to rotate the winding roller 15, they first pull the handle 17 outward. At this time, the hemisphere 19 will be disengaged from the ball groove 1901, and the first spring 18 will be deformed. At this time, the handle 17 can rotate freely, so that the subsequent rotation of the handle 17 can drive the winding roller 15 to rotate. The practicality of the device is further guaranteed by the setting of the locking assembly, which not only ensures the stability of the filter plate 8, but also ensures the sealing effect of the sealing plate 6 on the air inlet duct 4. It is highly practical and easy to operate.

[0031] Furthermore, the sealing assembly includes a trapezoidal sealing block 20, which is slidably connected to the inside of the transverse groove 21. The inside of the transverse groove 21 is fixedly connected to a guide rod 22, and the trapezoidal sealing block 20 is slidably sleeved on the surface of the guide rod 22. A second spring 23 is fixedly connected between the trapezoidal sealing block 20 and the transverse groove 21, and the second spring 23 is sleeved on the outside of the guide rod 22. When the staff installs the filter plate 8, by pressing the filter plate 8 downward, the filter plate 8 will contact the inclined surfaces of the two trapezoidal sealing blocks 20, thereby pushing the two trapezoidal sealing blocks 20 to both sides. At this time, the second spring 23 will be deformed. When the filter plate 8 is to be removed, the elastic force of the second spring 23 itself will make the two trapezoidal sealing blocks 20 closed, and finally the trapezoidal sealing block 20 is sealed to the through groove 7. The setting of the sealing assembly further improves the sealing effect of the air inlet duct 4, prevents external air from entering the air inlet duct 4, and further improves the practicality of the device and the subsequent combustion effect.

[0032] In the above embodiment, when the second L-shaped connecting block 12 is inserted into the card slot 14 and fixes the filter plate 8, the sealing plate 6 rotates 90 degrees counterclockwise, and the air inlet channel 4 is now connected to the outside. When the second L-shaped connecting block 12 is disengaged from the card slot 14 and the filter plate 8 is unlocked, the sealing plate 6 rotates 90 degrees clockwise, and the air inlet duct 4 is sealed.

[0033] Working principle:

[0034] When the oxygen-enriched burner is in use, when the staff needs to disassemble and clean the filter plate 8, they first drive the rotation of the bidirectional threaded rod 10 through the driving assembly. The rotation of the bidirectional threaded rod 10 can drive the two first L-shaped connecting blocks 11 to slide inside the guide groove 9, and the first L-shaped connecting block 11 can drive the movement of the second L-shaped connecting block 12. At this time, the second L-shaped connecting block 12 will slide inside the sliding groove 13, and then the second L-shaped connecting block 12 will be disengaged from the inside of the card slot 14, thereby no longer fixing the filter plate 8. At the same time, the movement of the driving assembly will also synchronously drive the rotation of the shaft body 601, and the rotation of the shaft body 601 will drive the rotation of the sealing plate 6, and finally achieve the sealing plate 6 to seal the front end of the air inlet duct 4 while releasing the lock on the filter plate 8.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
