Description

Technical Field

[0001] This utility model relates to the field of combustion nozzle technology, and in particular to a combustion nozzle. Background Technology

[0002] Combustion nozzles are key components for mixing and burning fuel and oxidizer. They are widely used in aero-engines, industrial burners and other fields. They mix fuel and oxidizer to form a combustible mixture, and improve combustion efficiency, stabilize the flame, and prevent flameout or backfire through atomization (liquid fuel) or diffusion (gaseous fuel).

[0003] Currently, during the use of the burner nozzle, foreign objects inevitably adhere to the top of the burner nozzle. As the foreign objects accumulate, they may clog the burner nozzle, thus affecting its normal use. However, there are still the following shortcomings: after disassembling the burner nozzle, it is difficult to manually clean the blockage, and the cleaning effect is not obvious. At the same time, it may damage the gas stove burner nozzle, thereby damaging the gas stove burner nozzle. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a combustion nozzle that eliminates the need for disassembly, automatically cleans impurities from the nozzle, and prevents clogging.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a combustion nozzle, comprising: The nozzle disc has an internal cavity. The nozzle head, located at the top of the nozzle disc, is used to burn the ejected fuel; The drive unit is located inside the nozzle disc; A collection box is located at the bottom of the nozzle disc; A nozzle cleaning component is disposed inside a nozzle disc. The drive unit is used to drive the nozzle cleaning component to automatically clean impurities on the nozzle head and prevent clogging of the nozzle head. A scraper is disposed below the nozzle cleaning component and fits against the inner wall of the nozzle disk. The scraper engages with the drive unit. The scraper is used to discharge impurities inside the nozzle disk. The collection box is used to collect the impurities. The protective cover is rotatably mounted inside the nozzle disc and is fixedly connected to the scraper to prevent impurities from damaging the drive unit and the meshing part of the scraper.

[0006] Furthermore, the nozzle head includes a cover plate disposed on the nozzle disk and a protrusion disposed in the middle of the cover plate, and a first spray hole is provided on the protrusion. It also includes a raised ring disposed on the cover plate and located outside the raised portion, and the raised ring is provided with a second spray hole.

[0007] Furthermore, the scraping component includes a support ring disposed inside the nozzle disc and a toothed disc disposed on the support ring; It also includes a limiting ring installed inside the nozzle disk to limit the upper and lower positions of the toothed disk; It also includes a cleaning brush located at the bottom of the toothed disc for cleaning the bottom of the nozzle disc; The drive unit meshes with the gear disk to drive the gear disk to rotate, and the bottom wall of the nozzle disk is provided with a conical body.

[0008] Furthermore, the nozzle cleaning component includes a connecting rod disposed on the gear plate and a first cleaning part disposed on the connecting rod; It also includes a track disposed inside the nozzle disc and a second cleaning part disposed on top of the track and movably connected to the first cleaning part, the first cleaning part and the second cleaning part being used to clean the nozzle head.

[0009] Furthermore, the first cleaning part includes a first support post disposed on the connecting rod and a first connector disposed on the first support post, wherein a groove is provided on the first support post; It also includes a first spring disposed on the first connector, and the first spring is provided with a first cleaning rod.

[0010] Furthermore, the track includes a retaining ring disposed within the nozzle disc and located above the protective cover, and protrusions evenly distributed on the top of the retaining ring.

[0011] Furthermore, the second cleaning part includes a second support post disposed on the fixed ring, and the second support post is slidably connected to the groove on the first support post; It also includes two second connectors set at an angle on the second support column, each of the two second connectors having a second spring at its end, and the end of the second spring having a second cleaning rod.

[0012] The beneficial effects of this utility model are reflected in: This invention utilizes a drive unit to rotate a toothed disc on a scraper between a support ring and a limiting ring. The toothed disc then rotates a connecting rod and a first support column on a nozzle cleaning component. The first support column then drives a first connecting component, a first spring, and a first cleaning rod to clean the first nozzle on the protrusion. The first support column then drives a second support column to rotate on a fixed ring and to move up and down on a protrusion. The second support column moves up and down on a groove in the first support column. The second cleaning rod on the second support column, under the action of a second spring, cleans the second nozzle on the protrusion ring. A protective cover protects the toothed disc and drive unit to prevent impurities from falling onto the toothed disc. The toothed disc then drives a cleaning brush to clean impurities from the nozzle disc, which are discharged into a collection box. This achieves automatic cleaning of the combustion nozzle without disassembling it, preventing clogging. Attached Figure Description

When the second pillar 53 rotates around the first pillar 52, the second cleaning rod 58 cleans the second spray holes in a cycle. When the second cleaning rod 58 moves away from the second spray hole, the inner wall of the protruding ring 23 squeezes the second cleaning rod 58 and the second spring 57. When the second cleaning rod 58 rotates to the second spray hole, the second spring 57 relaxes, driving the second cleaning rod 58 to clean the second spray hole.
