Detailed Description
The present invention is illustrated by the following examples, but the present invention is not limited to these examples. Modifications to the embodiments of the utility model or equivalent substitutions of parts of technical features without departing from the spirit of the utility model are intended to be covered by the scope of the claims of the utility model.
The first embodiment is as follows:
referring to fig. 1-6, a fire cover is shown, which comprises a fire cover body 1 and a metal column 2, wherein a fire hole structure 3 is arranged on the side wall of the fire cover body 1, an installation groove 4 is formed by the downward depression of the top of the fire cover body 1, the installation groove 4 is communicated with the fire hole structure 3, and the metal column 2 penetrates through the fire hole structure 3 and is inserted into the installation groove 4.
The utility model provides a fire cover, wherein a mounting groove 4 is communicated with a fire hole structure 3, and a metal column 2 is inserted in the mounting groove 4, namely the metal column 2 penetrates through the fire hole structure 3 when inserted in the mounting groove 4, and when the fire cover is normally used and fuel gas flows out from the fire hole structure 3 on the fire cover, the metal column 2 has a blocking effect on the fuel gas, so that the fuel gas flow rate is reduced, and the problem of flame separation during combustion is solved.
When the gas-cooker was closed, the inside pressure of fire lid reduced, and the gas can flow back to inside the fire lid to produce flame-out noise, the setting up of metal column 2 prevents that the gas from flowing back to inside the fire lid from fire hole structure 3, thereby avoids flame-out noise.
Traditional fire lid is processed with brass, and flame direct combustion yielding inserts and establishes metal column 2, and metal column 2 adopts high temperature resistant and the great metal material of hardness, avoids fire lid to warp.
A gas cavity 11 is formed in the fire cover body 1, and the cross-sectional area of the metal column 2 is gradually increased from one end close to the gas cavity 11 to one end far away from the gas cavity 11.
Preferably, the cross section of the metal column 2 is triangular.
In this embodiment, the metal pillar 2 is a triangular prism. The triangular prism includes a first inclined slope 21, a second inclined slope 22, and a flat surface 23. First inclined plane 21 and the one end of second inclined plane 22 are connected, just the junction orientation of first inclined plane 21 and second inclined plane 22 the gas chamber 11, first inclined plane 21 is by being close to the one end of gas chamber 11 is to keeping away from the one end of gas chamber 11 leans out the setting, second inclined plane 22 is by being close to the one end of gas chamber 11 is to keeping away from the one end of gas chamber 11 inclines the setting outwards, planar 23 one end with the other end of first inclined plane 21 is connected, planar 23 the other end with the other end of second inclined plane 22 is connected, planar 23 sets up and is keeping away from the one end of gas chamber 11.
The width of one end, far away from the gas cavity 11, of the metal column 2 is smaller than the diameter of the fire hole structure 3. I.e. the width of the widest cross-section of the metal pillar 2 is smaller than the diameter of the fire hole structure 3. So as to form a first air inlet passage 51 between the first inclined surface 21 and the inner wall of the fire hole structure 3 and a second air inlet passage 52 between the second inclined surface 22 and the inner wall of the fire hole structure 3. And the cross sections of the first air inlet channel 51 and the second air inlet channel 52 are gradually reduced from one end close to the gas cavity 11 to one end far away from the gas cavity 11.
The gas is followed when gas chamber 11 flows out through fire hole structure 3, first inlet channel 51 and second inlet channel 52 need flow through, because the setting of metal column 2, first inlet channel 51 with second inlet channel 52 is by being close to gas chamber 11's one end extremely keeps away from the one end cross section of gas chamber 11 reduces gradually, has reduced the gas velocity of flow, has solved the problem that the combustor burning leaves the flame. The arrangement of the first inclined plane 21 and the second inclined plane 22 ensures air intake, reduces the flow rate of gas, and reduces noise due to smooth transition of air flow.
The plane 23 is arranged at one end far away from the gas cavity 11, the first inclined plane 21 and the second inclined plane 22 are connected, when the gas stove is closed, the pressure inside the fire cover is reduced, and the plane 23 of the metal column 2 prevents gas from flowing back to the inside of the fire cover from the fire hole structure 3, so that flameout noise is avoided.
The metal column 2 and the mounting groove 4 are equal in size and adaptive in shape. Avoid metal column 2 to install produce the installation unstable or rock phenomenon such as etc. in the mounting groove 4.
Fire hole structure 3 includes first fire hole 31 and second fire hole 32 of arranging, first fire hole 31 sets up the second is arranged the top of fire hole 32.
The mounting groove 4 is communicated with the first fire hole 311 and/or the second fire hole 321, and the metal column 2 penetrates through the first fire hole 311 and/or the second fire hole 321 to be inserted into the mounting groove 4.
In this embodiment, the mounting groove 4 is formed by the top of the fire cover body 1 being recessed downward to penetrate through the first fire hole 311, the metal column 2 is inserted into the mounting groove 4 and penetrates through the first fire hole 311, and the second fire hole 321 is not penetrated through the metal column 2. That is, the number and distribution of the mounting grooves 4 are the same as those of the first fire holes 311.
Example two:
a burner comprising a fire cover as described in the first embodiment. When the combustor normally used, when the gas was covered from the fire pore structure 3 through the fire and flowed out, because mounting groove 4 passed fire pore structure 3 just metal column 2 is inserted and is established in mounting groove 4, promptly metal column 2 is inserted and is established having passed during in the mounting groove 4 fire pore structure 3, metal column 2 has the effect of blockking to the gas to reduce the gas velocity of flow, solved the combustor burning from the problem of flame.
When the gas-cooker was closed, the inside pressure of fire lid reduced, and the gas can flow back to inside the fire lid to produce flame-out noise, the setting up of metal column 2 prevents that the gas from flowing back to inside the fire lid from fire hole structure 3, thereby avoids flame-out noise.
Traditional fire lid is processed with brass, and flame direct combustion yielding inserts and establishes metal column 2, and metal column 2 adopts high temperature resistant and the great metal material of hardness, avoids fire lid to warp.
The above preferred embodiments should be considered as examples of the embodiments of the present application, and technical deductions, substitutions, improvements and the like similar to, similar to or based on the embodiments of the present application should be considered as the protection scope of the present patent.
