Description

Technical Field

[0001] This utility model relates to the field of burner accessories technology, specifically to an anti-rotation structure for a burner distributor. Background Technology

[0002] A burner is a device that mixes fuel and air in a specific way for combustion, and is widely used in industrial boilers, household stoves, and other fields. Its core function is to achieve efficient and stable combustion while reducing pollutant emissions by precisely controlling the fuel-air mixing ratio, injection speed, and method. The burner distributor, also known as the flame spreader, is a key component of the burner, responsible for evenly distributing the mixed gas to the flame holes to ensure flame stability. Its design requires adjusting the size, number, and distribution of the flame holes according to the type of gas to adapt to different combustion characteristics. High-quality burner distributors use high-temperature and corrosion-resistant materials and have optimized flame hole structures to improve thermal efficiency and reduce the generation of harmful gases.

[0003] Utility model patent CN218626831U discloses a burner distributor seat, relating to the field of gas stove equipment. It includes a burner cap base, comprising an inner ring and an outer ring. The inner and outer rings are connected by several gas supply pipes arranged at equal angles, with the pipes angled upwards to form a gas supply channel. An inner burner cap is fitted onto the inner ring, with a central flame hole. Several inner and outer flame holes are arranged on the outer sides of both the inner and outer burner caps. The base has thermocouple and igniter holes. This burner distributor seat allows the central flame hole to emit a central flame, the inner flame hole to emit an inner flame, and the outer flame hole to emit an outer flame, creating a multi-layered, encircling combustion effect on the bottom of the pot, improving heat transfer efficiency. This design is suitable for Chinese cooking habits. Furthermore, the inner ring of the outer ring and the corresponding inner ring of the outer burner cap are threaded together, solving the inconvenience of traditional screw connections and making disassembly and maintenance easier.

[0004] However, common burner distributors are prone to misalignment of the flame holes and gas outlets under external forces such as collisions with cookware. After the distributor rotates, the flame distribution in the inner and outer rings becomes unbalanced, resulting in a decrease in thermal efficiency. Therefore, a burner distributor anti-rotation structure is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a burner distributor anti-rotation structure, which has the advantages of preventing the distributor from rotating by positioning it radially and axially, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A burner distributor anti-rotation structure includes a mounting base, a central mounting cylinder fixedly mounted at the top center of the mounting base, a connecting pipe fixedly mounted on the top of the mounting base, and a bidirectional positioning component provided on the top of the connecting pipe. The bidirectional positioning assembly includes radial positioning teeth fixedly installed on the top of the connecting pipe. A flare distribution cap is placed on the top of the connecting pipe. A radial positioning groove adapted to the radial positioning teeth is opened on the inner side wall of the flare distribution cap. A mounting crossbar is fixedly installed inside the flare distribution cap. A mounting top plate is fixedly installed at one end of the mounting crossbar. An axial positioning screw is passed through the top of the mounting top plate. The axial positioning screw is threadedly connected to the central mounting cylinder.

[0007] Furthermore, the axial positioning screw has a central output hole at its top, the ignition top cover has a central hole at its top, the ignition top cover has a chamfer at its top, and the chamfer of the ignition top cover has a lateral hole at its top.

[0008] Furthermore, a central mounting tube is fixedly installed at the top center of the mounting base, and a central mounting cylinder is located inside the central mounting tube.

[0009] Furthermore, a central slot is provided on the surface of the intermediate mounting tube, a central cover is fitted on the top of the intermediate mounting tube, and a central block that matches the central slot is provided on the inner side wall of the central cover.

[0010] Furthermore, the top of the center cover is provided with a positioning through hole, the top of the center mounting cylinder is provided with a positioning screw hole, the axial positioning screw is adapted to the positioning through hole, and the axial positioning screw is threadedly connected to the positioning screw hole.

[0011] Furthermore, the top of the center cover is provided with a center side hole, and the side wall of the center mounting cylinder is provided with a fire distribution hole.

[0012] Furthermore, an input pipe is fixedly installed at the bottom center of the mounting base, a fire distribution channel is opened inside the inclined wall of the mounting base, and a support frame is fixedly installed at the bottom of the mounting base.

[0013] Compared with the prior art, this utility model provides a burner distributor anti-rotation structure, which has the following beneficial effects: This anti-rotation structure for the burner distributor uses radial positioning teeth on the connecting pipe at the top of the mounting base and radial positioning grooves inside the distributor top cover. When installing the distributor top cover, the radial positioning grooves are aligned with the radial positioning teeth to radially fix the cover and prevent rotation. A positioning screw hole is provided at the top of the central mounting cylinder, and a mounting crossbar and mounting top plate are installed inside the distributor top cover. The mounting top plate is locked to the central mounting cylinder by axial positioning screws to axially fix the distributor top cover and prevent it from moving upwards, thus separating the distributor top cover from the connecting pipe. This solves the common problem of burner distributors where, under external forces such as pot collisions, the flame holes and exhaust ports are easily misaligned, leading to an imbalance in the inner and outer flame distribution after the distributor rotates, resulting in decreased thermal efficiency.
