Description

Technical Field

[0001] The present invention relates to the technical field of gas stoves, and in particular to an energy-saving, environmentally friendly, and silent detachable burner head. Background Art

[0002] A gas stove refers to a kitchen appliance that uses gas fuels such as liquefied petroleum gas (liquid), artificial coal gas, and natural gas for ignition and heating. A gas stove generally consists of a burner, valve body, shell, stove rack, igniter and other accessories. The burner is an important component of the gas stove. The combustion of the fuel, flame direction and degree of combustion are directly affected by the burner structure.

[0003] However, in existing gas stoves, when burning (for example, a utility model patent with authorization announcement number CN217503661U previously applied for by the applicant), the gas is ignited directly at the burner head for combustion, and the size of the combustion flame is changed by simply adjusting the gas intake volume. This combustion method has low combustion efficiency and insufficient gas combustion. In addition, due to the fixed design structure of the existing burner head, the burner head is not easy to disassemble for cleaning. Summary of the Invention

[0004] In response to the defects in the prior art, the purpose of the present invention is to provide an energy-saving, environmentally friendly and silent detachable burner head, which aims to solve the problem of low combustion efficiency caused by the existing burner head structure and relying on simply adjusting the gas intake volume to change the size of the combustion flame.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] The present application provides an energy-saving, environmentally friendly, silent, detachable burner head, the burner head comprising a shell, a built-in air outlet ring being provided on the upper portion of the shell, the burner head further comprising:

[0007] An external air-air mixing fire ring, comprising a plurality of annular combustion plates and a sealing plate, wherein the plurality of combustion plates are stacked in sequence along the height direction, and a plurality of internal and external through-going combustion holes are formed between adjacent pairs of the combustion plates, and the plurality of combustion holes are evenly spaced along the circumferential direction of the combustion plates. The sealing plate is horizontally and sealingly mounted on the top of the combustion plate located on the uppermost layer, and the external air-air mixing fire ring is arranged in the inner cavity of the built-in air outlet ring;

[0008] An internal air-air mixing inlet pipe, the top end of which is connected to the external air-air mixing fire outlet ring, and the end surface of which is provided with a plurality of air inlet holes;

[0009] A main air pipe, the top end of which extends into the inner cavity of the internal air mixing inlet pipe, and the main air pipe is connected to the inner cavity of the internal air mixing inlet pipe through an air outlet provided at the top end thereof;

[0010] A main air duct, the main air duct being sleeved on the outer circumference of the inner air mixing inlet pipe, the main air duct being arranged at the upper end of the inner air mixing inlet pipe, the inner cavity of the main air duct being connected to the inner cavity of the shell, the built-in air outlet ring being installed in the inner cavity of the shell, and the built-in air outlet ring being connected to the inner cavity of the shell;

[0011] An air-air intersection tee is mounted on the outer peripheral surface of the inner air-air mixing inlet pipe, and the air-air intersection tee is arranged at the lower end of the inner air-air mixing inlet pipe. The upper end of the air-air intersection tee is tightly connected to the main air duct, wherein the air supplied from the outside enters the built-in air outlet ring from the main air duct through the air inlet of the air-air intersection tee and flows to the outer surface around the external air-air mixing fire outlet ring, so that the combustion flame at the external air-air mixing fire outlet ring burns more vigorously.

[0012] Furthermore, the shell includes an upper shell and a lower shell, and the top outer edge of the lower shell is provided with a receiving groove for placing the bottom outer edge of the upper shell, and the bottom outer edge of the upper shell is fitfully placed in the receiving groove of the lower shell, and the external air mixing and fire outlet ring is threadedly installed on the top of the internal air mixing inlet pipe, and the bottom end of the upper shell is pressed and installed on the lower shell through the external air mixing and fire outlet ring.

[0013] Furthermore, the plurality of air inlet holes are staggeredly arranged along the circumferential direction of the outer surface of the inner air mixing inlet pipe.

[0014] Furthermore, there are multiple air outlet holes on the main air pipe, and the multiple air outlet holes are arranged at the top end of the main air pipe.

[0015] Furthermore, a connecting piece is provided at the mounting hole at the bottom end of the lower shell, a mounting hole for the internal air mixing pipe to pass through is provided at the center position of the connecting piece, and a plurality of air inlet holes are arranged along the circumferential direction on the outer edge of the mounting hole, the connecting piece is pressed and fitted into the mounting hole through the main air duct, and the main air duct is connected with the inner cavity of the shell through the air inlet hole.

The gas enters the outer ring of the second combustion chamber directly through the main air pipe and is ignited to generate a combustion flame. At the same time, the air injected from the outside enters the inner ring of the shell directly through the main air pipe. The air entering the inner ring of the shell is converged from all sides through the built-in air outlet pipe to the combustion flame at the external ring of the second combustion chamber located at the center. The air blown in from all sides of the inner wall of the built-in air outlet pipe can make the combustion flame at the external ring of the second combustion chamber more vigorous and the combustion efficiency higher, thereby changing the traditional technical method of simply increasing the size of the combustion flame by adjusting the gas supply. In addition, this internal fire and external wind structure (that is, the flame burns at the external ring of the second combustion chamber arranged at the center of the shell, and the wind is provided to the center by the built-in air outlet ring arranged at the outer edge of the shell) improves the roaring sound caused by the traditional simultaneous outflow of air and gas for combustion, and reduces the noise generated during combustion.

By dividing the shell into a detachable upper shell and lower shell structure, the external air-air mixing fire ring is cleverly detachably locked and installed at the top of the internal air-air mixing inlet pipe, and the upper shell is tightly pressed on the lower shell. When disassembling, it is only necessary to simply loosen the external air-air mixing fire ring from the top of the internal air-air mixing inlet pipe to achieve separation and disassembly between the upper shell and the lower shell, that is, to achieve disassembly and replacement of the upper shell.

DETAILED DESCRIPTION

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] See attached Figures 1 to 6 As shown, this embodiment provides an energy-saving, environmentally friendly and silent detachable burner head 100, which includes a shell 2, a built-in air outlet ring 1, an external air and gas mixing fire outlet ring 3, an internal air and gas mixing inlet pipe 4, a main air pipe 6, a main air pipe 7 and an air and gas connecting tee 5.

[0040] Continue to refer to the attached Figures 1 to 6 As shown, the built-in air outlet ring 1 is installed in the upper inner cavity of the shell 2, and the external air and gas mixing and fire outlet ring 3 is installed in the upper inner cavity of the shell 2 and is located at the center of the built-in air outlet ring 1, that is, the external air and gas mixing and fire outlet ring 3 is installed at the center of the built-in air outlet ring 1.

[0041] Continue to refer to the attached Figures 1 to 6 As shown, the top end of the internal air-air mixing inlet pipe 4 extends into the inner cavity of the shell 2 and is connected to the bottom end of the external air-air mixing fire ring 3 through a thread. The main gas pipe 6 is sleeved in the inner cavity of the internal air-air mixing inlet pipe 4. The bottom end of the main gas pipe 6 is connected to the gas inlet. The gas is supplied to the external air-air mixing fire ring 3 through the main gas pipe 6. Figure 10 As described above, a plurality of air outlet holes are provided on the outer surface of the top end of the main air pipe 6 along the circumferential direction. The gas entering the main air pipe 6 flows into the inner cavity of the internal air mixing inlet pipe 4 through the air outlet hole 61 and flows to the external air mixing fire outlet ring 3.

[0042] Refer to the attached Figures 2 to 3 As shown in Figures 5 and 6, the main air duct 7 is sleeved on the outer circumference of the internal air mixed inlet pipe 4. The main air duct 7 is arranged at the upper end of the internal air mixed inlet pipe 4. The inner cavity of the main air duct 7 is connected to the inner cavity of the shell 2, and the built-in air outlet ring 1 is connected to the inner cavity of the shell 2. Figure 4 As shown, a connecting piece 8 is further provided at the mounting connection hole 9 between the shell 2 and the main air duct 7. A mounting hole 81 for the internal air mixing inlet pipe 4 to pass through is provided at the center of the connecting piece 8. A plurality of air inlet holes 82 are arranged along the circumferential direction on the outer edge of the mounting hole 81. During installation, the top end of the main air duct 7 is installed in the mounting connection hole 9 at the bottom end of the shell 2. At the same time, the top end of the main air duct 7 presses the connecting piece 8 tightly and fits it at the bottom end of the mounting hole 81. In this way, the air entering the main air duct 7 can flow into the inner cavity of the shell 2 through the air inlet holes 82. The air entering the inner cavity of the shell 2 then converges into the built-in air outlet ring 1, providing air flow to the external air mixing outlet ring 3 at the center.

[0043] Continue to refer to the attached Figures 1 to 6 As shown, the air-air intersection tee 5 is sleeved on the outer peripheral surface of the inner air-air mixing inlet pipe 4 , the air-air intersection tee 5 is arranged at the lower end of the inner air-air mixing inlet pipe 4 , and the upper end of the air-air intersection tee 5 is fastened to the main air duct 7 .

[0044] Refer to the attached Figure 4 、 7As shown in Figure 9, a plurality of air inlet holes 41 are provided on the outer surface of the lower end portion of the inner air mixing inlet pipe 4 at the position corresponding to the air intersection tee 5, so that a part of the air entering the air intersection tee 5 can enter the inner air mixing inlet pipe 4 through the air inlet holes 41, mix with the gas entering the inner air mixing inlet pipe 4, and flow together to the external air mixing fire ring 3 for ignition. At the same time, most of the air supplied from the outside enters the built-in air outlet ring 1 through the main air duct 7 and flows to the outer surface of the external air-air mixing fire outlet ring 3. The air blown in from the inner wall of the built-in air outlet ring 1 can make the combustion flame at the external air-air mixing fire outlet ring 3 more vigorous and the combustion efficiency higher, which changes the traditional simple technical method of increasing the size of the combustion flame by only adjusting the gas supply. In addition, this kind of internal fire and external wind structure (that is, the flame burns at the external air-air mixing fire outlet ring 3 arranged at the center position of the shell 2, and the wind is provided to the center position by the built-in air outlet ring 3 arranged at the outer edge of the shell 2) improves the traditional roaring sound caused by the simultaneous flow of air and gas for combustion, and reduces the noise generated during combustion.

[0045] Combined with reference to Figures 1 to 4 And attached Figures 11 to 12 As shown, in order to improve the traditional shell because it is an integral seal and cannot be disassembled, and the shell is a consumable part, in the case of damage or burnt, it needs to be replaced by professionals, resulting in increased after-sales maintenance costs. In view of this, the shell in this embodiment is composed of an upper shell 21 and a lower shell 22. It should be noted here that since the inner cavity of the shell 2 in this embodiment is only used for air circulation, it does not require the traditional strict sealing treatment of the inner cavity of the shell. Therefore, the interior of the shell in this embodiment does not need to be sealed, and its structure is simpler, safer and more reliable. Refer to the attached Figure 11 and 12 As shown, in this embodiment, the top outer edge of the lower shell 22 is provided with a receiving groove 221 for placing the bottom outer edge of the upper shell 21, and the bottom outer edge of the upper shell 21 is fitly placed in the receiving groove 221 of the lower shell 22, and the external air and gas mixing and fire-emitting ring 3 is threadedly installed on the top of the internal air and gas mixing inlet pipe 4, and the bottom end of the upper shell 21 is pressed and installed on the lower shell 22 through the external air and gas mixing and fire-emitting ring 3. That is, after the external mixing air outlet ring 3 is threadedly installed on the internal air mixing inlet pipe 4, the bottom end of the external mixing air outlet ring 3 is pressed tightly against the bottom end of the upper shell 21. It can be understood that since the external mixing air outlet ring 3 exerts downward pressure on the bottom end face of the upper shell 21, the upper shell 21 can be pressed tightly against the lower shell 22; and when the external mixing air outlet ring 3 is loosened from the top end of the internal air mixing inlet pipe 4, the external mixing air outlet ring 3 loses the pressure acting on the upper shell 21, and the operator can easily separate the upper shell 2 from the lower shell 22.

[0046] During disassembly, it is only necessary to simply unscrew the external air-air mixing fire ring 3 from the top of the internal air-air mixing inlet pipe 4 to achieve separation and disassembly between the upper shell 21 and the lower shell 22, that is, to achieve disassembly and replacement of the upper shell 21.

[0047] Refer to the attached Figure 13 and 14 As shown, in this embodiment, the external air-gas mixing fire ring 3 includes a plurality of annular combustion plates 31 and a sealing plate 33. The plurality of combustion plates 31 are stacked in sequence along the height direction. A plurality of combustion holes 32 that penetrate inside and outside are formed between a pair of adjacent combustion plates 31. The plurality of combustion holes 32 are evenly spaced along the circumferential direction of the combustion plates 31. The sealing plate 33 is horizontally sealed and installed on the top of the combustion plate 31 located on the uppermost layer. In some embodiments, the cross-section of the combustion hole 32 is a trapezoidal cross-sectional structure, and the aperture size of the combustion hole 32 is an outer structure that gradually increases from the inside to the outside (it should be noted here that this part of the structure is the same as the structure in the patent previously applied for by the applicant, and the authorization announcement number of the previous patent is a utility model patent CN217503661U).

[0048] For ease of understanding, the working principle of the energy-saving, environmentally friendly and silent detachable burner head in this embodiment is described below:

[0049] Refer to the attached Figure 15 As shown, the external gas is transported upward through the main gas pipe 6, and the gas entering the main gas pipe 6 enters the inner cavity of the internal air-air mixing inlet pipe 4 through the air outlet hole thereon. At the same time, part of the external air blown into the air-air junction tee 5 enters the internal air-air mixing inlet pipe 4 through the air inlet hole, mixes with the gas and flows together to the external air-air mixing fire ring 3 for ignition; at the same time, most of the air blown into the air-air junction tee 5 passes through the main air pipe 7, the air inlet hole 82, and the inner cavity of the shell 2 in turn and flows to the built-in air outlet ring 1, and is discharged from the built-in air outlet The inner walls of the ring 1 spray out air toward the external air-air mixing fire ring 3 located at the center. The flame located at the external air-air mixing fire ring 3 can burn more vigorously and fully with the help of wind, thereby improving the combustion efficiency of the gas. At the same time, this internal fire and external wind structure (that is, the flame burns at the external air-air mixing fire ring 3 arranged at the center of the shell 2, and the wind is provided to the center position by the built-in air outlet ring 1 arranged at the outer edge of the shell 2) improves the roaring sound caused by the traditional simultaneous flow of air and gas for combustion, and reduces the noise generated during combustion.

[0050] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
