Description

Technical Field

[0001] This application relates to the field of stove technology, and more particularly to a burner assembly. Background Technology

[0002] Currently, stoves come in two types: single-ring and double-ring. Single-ring stoves have a simple structure and small size, but their combustion efficiency is not as good as that of double-ring stoves. Double-ring stoves, on the other hand, have a complex structure, take up more space, and are not easy to integrate into smaller stoves. Utility Model Content

[0003] To address the aforementioned problems, this technical solution provides a burner assembly.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] A burner assembly, including

[0006] A base having two air inlets and two nozzle seats respectively connected to the two air inlets;

[0007] The burner head is provided with an outer premixing tube and an inner premixing tube respectively corresponding to the two nozzle seats, an outer ring, an inner ring, an outer ring cavity disposed on the outer ring and connected to the outer premixing tube, and an inner ring cavity disposed on the inner ring and connected to the inner premixing tube. The outer ring cavity includes a first groove bottom, a second groove bottom, and a third groove bottom that gradually rise; the inner ring cavity includes a fourth groove bottom, a fifth groove bottom, and a sixth groove bottom that gradually rise; the outer premixing tube penetrates into the inner ring cavity so that its outer wall forms the sixth groove bottom;

[0008] The base is provided with mounting holes for installing a ignition needle, and a locking mechanism for fixing the ignition needle in the mounting holes.

[0009] An outer fire cover, which is disposed on the outer annular cavity;

[0010] The inner fire cover is located on the inner annular cavity.

[0011] In a burner assembly as described above, the bottom of the outer annular cavity gradually rises in a counterclockwise direction, and the bottom of the inner annular cavity gradually rises in a clockwise direction.

[0012] In one burner assembly as described above, the outer premixing tube and the inner premixing tube connect the outer ring and the inner ring, such that the outer ring and the inner ring are spaced apart.

[0013] As described above, in a burner assembly, the locking mechanism includes a connecting hole on one side of the mounting hole, a tightening sleeve corresponding to the mounting hole, and a pressing sleeve corresponding to the connecting hole. The tightening sleeve has a sleeve hole for the ignition needle to pass through. The pressing sleeve engages with the inclined surface of the tightening sleeve to push the tightening sleeve to move, causing the sleeve hole to be misaligned with the mounting hole.

[0014] In one burner assembly as described above, a screw passes through the clamping sleeve and connects to the connecting hole to adjust the distance between the clamping sleeve and the base, thereby adjusting the moving distance of the tightening sleeve. This allows the tightening sleeve to move to a locking position where the sleeve hole and the mounting hole are misaligned, thus clamping the ignition needle; or to move the tightening sleeve to a loosening position where the sleeve hole and the mounting hole are coaxial, thus releasing the clamping of the ignition needle.

[0015] As described above, in a burner assembly, the base has a raised reinforcing rib at its bottom, and the reinforcing rib has a mounting platform formed by widening the rib. The connecting hole and the mounting hole are located on the mounting platform.

[0016] In one type of burner assembly as described above, the width of one side of the mounting platform corresponds to the width of the tightening sleeve, and the width of the other side corresponds to the width of the compression sleeve.

[0017] As described above, in a burner assembly, the base has a first mounting position and a second mounting position for mounting an ignition needle and a sensing needle, respectively, wherein the distance from the first mounting position to the center of the base is less than the distance from the mounting hole to the center of the base.

[0018] In one burner assembly as described above, the burner head is provided with a clearance notch for making way for an ignition needle, the clearance notch being located in the gap between the outer ring and the inner ring.

[0019] The beneficial effects of this application are:

[0020] This invention provides a burner assembly that utilizes the outer wall of the outer premixing tube to form the bottom of the sixth groove in the inner annular cavity, thereby reducing volume and simplifying the structure while improving connection strength. Attached Figure Description

[0029] The base 1 is provided with a mounting hole 13 for installing a ignition needle, and a locking mechanism 3 for fixing the ignition needle in the mounting hole 13.

[0030] Outer fire cover 4, which is disposed on the outer annular cavity 25;

[0031] The inner fire cover 5 is disposed on the inner annular cavity 26.

[0032] This invention provides a burner assembly that utilizes the outer wall of the outer premixing tube to form the bottom of the sixth groove in the inner annular cavity, thereby reducing volume and simplifying the structure while improving connection strength.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the bottom of the outer annular cavity 25 gradually rises counterclockwise, and the bottom of the inner annular cavity 26 gradually rises clockwise. This is beneficial for increasing the injection pressure and allowing for more complete combustion.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the outer premixing pipe 21 and the inner premixing pipe 22 connect the outer ring 23 and the inner ring 24, such that the outer ring 23 and the inner ring 24 are spaced apart. The outer premixing pipe and the inner premixing pipe also serve as a connecting structure, which helps to reduce volume.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the locking mechanism 3 includes a connecting hole 31 on one side of the mounting hole 13, a tightening sleeve 32 corresponding to the mounting hole 13, and a pressing sleeve 33 corresponding to the connecting hole 31. The tightening sleeve 32 is provided with a sleeve hole 34 for the ignition needle to pass through. The pressing sleeve 33 engages with the inclined surface of the tightening sleeve 32 to push the tightening sleeve 32 to move, so that the sleeve hole 34 is misaligned with the mounting hole 13.

[0036] Furthermore, as a preferred embodiment of this solution, and not a limitation thereof, the screw passes through the clamping sleeve 33 and connects to the connecting hole 31 to adjust the distance between the clamping sleeve 33 and the base 1, thereby adjusting the moving distance of the tightening sleeve 32. This allows the tightening sleeve 32 to move to a locking position where the sleeve hole 34 is misaligned with the mounting hole 13, thus clamping the ignition needle; or to move the tightening sleeve 32 to a loosening position where the sleeve hole 34 and the mounting hole 13 are coaxial, thus releasing the clamped ignition needle. Existing ignition needle installation requires complete disassembly of the retaining sleeve to replace the ignition needle, which is cumbersome due to the limited space in the ignition needle's installation location. By rotating the screw, the ignition needle can be loosened or fixed, making the operation simple.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the base 1 has a raised reinforcing rib 14 at its bottom, and a mounting platform 15 formed by widening the reinforcing rib 14 is provided on the reinforcing rib 14. The connecting hole 31 and the mounting hole 13 are located on the mounting platform 15. This increases the strength of the connecting hole and the mounting hole.

[0038] Furthermore, as a preferred embodiment of this solution and not a limitation, the width of one side of the mounting platform 15 corresponds to the width of the tightening sleeve 32, and the width of the other side corresponds to the width of the pressing sleeve 33. This avoids incorrect assembly positioning and allows for proper installation even in environments with no visibility.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the base 1 is provided with a first mounting position 16 and a second mounting position 17 for mounting the ignition needle and the sensing needle, respectively, wherein the distance from the first mounting position 16 to the center of the base 1 is less than the distance from the mounting hole 13 to the center of the base 1.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the burner head 2 is provided with a clearance notch 27 for making way for the ignition needle, the clearance notch 27 being located in the gap between the outer ring 23 and the inner ring 24.

[0041] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
