DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Figure 1It is a three-dimensional diagram of a multi-ring fire divider of the present invention. The present invention provides a multi-ring fire divider, including a fire cover 1 and a base 2. The fire cover 1 is arranged above the base 2. A fire hole 130 is arranged on the outer surface of the fire cover 1. The fire cover 1 and the base 2 are folded together to form an annular cavity 3, and the annular cavity 3 is connected to the fire hole 130. Specifically, the fire cover 1 is arranged above the base 2, and the fire hole 130 is arranged on the outer side of the fire cover 1. The fire hole 130 can also be arranged on the upper surface or inner side of the fire cover 1, and there is no restriction on the position of the fire hole 130. The shape of the fire hole 110 can also be circular, annular, arc-shaped, etc., and there is no restriction on the shape of the fire hole 11.

[0030] In order to prevent the air flow in the annular cavity 3 from generating turbulence, at least one air blocking structure 4 is provided in the annular cavity 3. The air blocking structure 4 is used to divide the annular cavity 3 into multiple ventilation cavities 5. No two adjacent ventilation cavities 5 are connected to each other. In this way, the air flow between the ventilation cavities 5 will not flow in series, so that the air flow is concentrated and the air pressure becomes larger, so that the flame at the fire hole 130 becomes longer, thereby increasing the thermal efficiency.

[0031] The fire cover 1 can be an outer ring fire cover, an inner ring fire cover or a middle ring fire cover, which is not limited here.

[0032] Figure 2 This is a front cross-sectional view of a multi-ring fire distributor according to the present invention. A first annular channel 6 is provided on the bottom surface of the fire cover 1, a second annular channel 7 is provided on the upper surface of the base 2, and the annular cavity 3 is formed by the first annular channel 6 and the second annular channel 7 from top to bottom. Specifically, to facilitate securing the fire cover 1 and the base 2 together, at least one first connecting boss 610 is provided within the first annular channel 6, and a second connecting boss 710 corresponding to the first connecting boss 610 is provided within the second annular channel 7. A fixing member passes through the first connecting boss 610 and is fixed to the second connecting boss 710. The provision of the first connecting boss 610 and the second connecting boss 710 facilitates securing the fire cover 1 and the base 2 together. The fixing member is generally a bolt, but rivets can also be used. The type of fixing member is not limited here.

[0033] Example 1

[0034] Figure 3 This is a three-dimensional diagram of an embodiment of a multi-ring fire distributor fire cover of the utility model. Figure 4This is a three-dimensional diagram of an embodiment of a multi-ring fire distributor base according to the present invention. The gas blocking structure refers to the first connecting boss 610 having two side surfaces connected to the two inner side walls of the first annular channel 6, and the second connecting boss 710 having two side surfaces connected to the two inner side walls of the second annular channel 7. When the fire cover 1 and the base 2 are closed together, the first connecting boss 610 and the second connecting boss 710 combine to form the gas blocking member 8. The first connecting boss 610 directly blocks the first annular channel 6, and the second connecting boss 710 blocks the second annular channel 7. The first connecting boss 610 and the second connecting boss 710 abut against each other to block the gap between the fire cover 1 and the base 2. That is to say, the first connecting boss 610 and the second connecting boss 710 are used to divide the annular cavity 3 into multiple ventilation cavities 5, and the ventilation cavities 5 are not connected to each other. In this way, no cross-flow and turbulence will occur between the ventilation cavities 5, so that the airflow is concentrated and the air pressure is increased, so that the flame at the fire hole 130 becomes longer, thereby increasing the thermal efficiency. The first connecting boss 610 and the second connecting boss 710 are directly used as gas blocking structures. The first connecting boss 610 and the second connecting boss 710 are both connected to the two inner walls of the annular cavity 3, which play a role in preventing cross-flow and turbulence. The structure is simple and the cost is low.

[0035] Example 2

[0036] Figure 5 This is a three-dimensional diagram of another embodiment of a multi-ring fire cover for a fire divider according to the present invention. The gas-blocking structure refers to the additional provision of at least one gas-blocking member 8 within the first annular channel 610. The two side surfaces of the gas-blocking member 8 are respectively connected to the two inner side walls of the annular cavity 3. The bottom surface of the gas-blocking member 8 abuts against the bottom surface of the second annular channel 710. The gas-blocking member 8 within the first annular channel 610, that is, the gas-blocking member 8 is directly provided on the fire cover 1. The gas-blocking member 8 is used to separate the annular cavity 3 into multiple sections of ventilation chambers 5, so that the ventilation chambers 5 are not connected to each other. This also prevents cross-flow and turbulence between the ventilation chambers 5, concentrates the airflow, increases the air pressure, and lengthens the flame at the fire outlet 130, thereby improving thermal efficiency. The existing first connecting boss 610 and the second connecting boss 710 are maintained. The existing first connecting boss 610 and the second connecting boss 710 are only connected to one of the inner walls of the annular cavity 3, and cannot play the role of preventing cross-flow and turbulence. Only the gas blocking component 8 plays the role of preventing cross-flow and turbulence.

[0037] Figure 6This is an explosion diagram of another embodiment of a multi-ring fire separator fire cover of the present invention. The fire cover 1 includes an annular baffle 110 and a cover plate 120. The first annular channel 6 is provided on the inner side of the annular baffle 110. The cover plate 120 is detachably connected to the annular baffle 110. There is a gap between the cover plate 120 and the annular baffle 110. This gap forms a fire hole 130. The upper surface of the gas blocking member 8 abuts against the top surface of the cover plate 120. The fire cover 1 is split into the annular baffle 110 and the cover plate 120. The fire hole 130 is formed by the gap between the annular baffle 110 and the cover plate 120. No additional processing of the fire hole 130 is required, and the cost is low. Specifically, the fire hole 130 is annular. Since the first annular channel 6 is directly connected to the fire hole 130, the gas blocking member 8 in the first annular channel 6 divides the fire hole 130 into multiple sections. When in use, the gas blocking member 8 is placed in alignment with the baking pot bracket so that the flame will not bake the pot bracket. In this way, the gas blocking member 8 prevents the generation of smoke.

[0038] Specifically, a connecting seat 620 is provided in the first annular channel 6, and a positioning column 121 corresponding to the connecting seat 620 is provided on the top surface of the cover plate 120. The positioning column 121 is clamped on the connecting seat 620. The structure is simple and facilitates the detachable connection between the cover plate 120 and the annular baffle 110.

[0039] Example 3

[0040] Figure 7 This is a perspective view of another embodiment of the multi-ring fire divider base of the present invention. A gas blocker 8 is installed within the second annular channel 7. Its two side surfaces are connected to the inner walls of the annular cavity 3, and its upper surface abuts the top surface of the first annular channel 6. The installation of the gas blocker 8 within the second annular channel 7, in other words, places the gas blocker 8 directly on the base 2. The gas blocker 8 separates the annular cavity 3, preventing the ventilation cavities 5 from communicating with each other.

[0041] The aforementioned gas blocking member 8 can be considered a blocking block, used to separate and seal the annular cavity 3. The shape of the gas blocking member 8 is not limited, as long as it prevents crossflow or diversion between adjacent ventilation cavities 5. The gas blocking member 8 serves to concentrate the airflow, preventing diversion and the resulting decrease in air pressure.

[0042] Example 4

[0043] Figure 8This is a three-dimensional diagram of the third embodiment of a multi-ring fire divider base of the utility model. When the first connecting boss 610 and the second connecting boss 710 are only connected to one of the inner side walls of the annular cavity 3, a gas blocking member 8 is also provided in the annular cavity 3. The gas blocking member 8 has an annular structure, and one side of the gas blocking member 8 abuts against the other inner side wall of the annular cavity 3, and the other side of the gas blocking member 8 abuts against the outer side surface of the first connecting boss 610 and the outer side surface of the second connecting boss 710 respectively. In this way, the gas blocking member 8 and the first connecting boss 610 and the second connecting boss 710 divide the annular cavity 3 into multiple ventilation chambers 5, and the ventilation chambers 5 are not connected to each other. However, in order to ensure that the ventilation chamber 5 is connected to the fire outlet 130, an air outlet is provided at the position of the gas blocking member 8 corresponding to the ventilation chamber 5. The upper surface of the gas blocking member 8 abuts against the top surface of the first annular channel 6, and the bottom surface of the gas blocking member 8 abuts against the bottom surface of the second annular channel 7. This gas blocking member 8 is directly stuck in the annular cavity 3, which is convenient for installation and disassembly. In this embodiment, the gas blocking member 8 is provided on the outer ring of the second annular channel 7, and the second connecting protrusion 710 is provided on the inner ring of the second annular channel 7. If the second connecting protrusion 710 is provided on the outer ring of the second annular channel 7, the gas blocking member 8 is provided on the inner ring of the second annular channel 7.

[0044] A gas stove comprises any one of the multi-ring flame distributors described above, wherein the base 2 is used for being installed on the gas stove.

[0045] Specifically, the principle of the present invention is to provide a gas blocking structure 4 in the annular cavity 3, and utilize the gas blocking structure 4 to divide the annular cavity 3 into multiple ventilation cavities 5. Adjacent ventilation cavities 5 are directly separated and not connected to each other. In this way, there will be no cross-flow between the ventilation cavities 5, so that the air flow is concentrated, the air pressure is high, the flame becomes longer, and the thermal efficiency is greatly improved.

[0046] Action process: Taking embodiment 1 as an example, the gas entering the annular cavity 3 is concentrated in the ventilation cavity 5, so that the air flow in the ventilation cavity 5 becomes larger, the flame at the fire hole 130 becomes longer, and the contact area between the flame 130 and the bottom of the pot is increased, thereby increasing the thermal efficiency.

[0047] On the basis of the above scheme, if various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
