Detailed Description

As shown in fig. 1 to fig. 3, in this embodiment, the utility model discloses a fire row 1 that a plurality of arranged in proper order, a plurality of the cooperation is provided with at least three venturi 2 in the fire row 1, and is three venturi 2's upper end all communicates, the cooperation of the up end of fire row 1 is provided with heating panel 3. Only be provided with one or two venturi and have the not enough condition of combustion power of fire row, at least three for conventional art generally venturi 2's setting makes 1's power increase is arranged to the fire, and the structure is compacter, and is more sufficient when drawing the air for the gas combustion is more abundant, reduces the emission of smoke pollutants, makes the utility model has the advantages of compact structure, combustion power are big and can burn fully.

In the present embodiment, the number of the venturi tubes 2 is three.

In this embodiment, venturi 2 include venturi top tube 4 and with venturi low tube 5 that the lower extreme of venturi top tube 4 is linked together, the inside of venturi top tube 4 up enlarges from bottom to top, the inside of venturi low tube 5 up contracts from bottom to top.

In this embodiment, the venturi tubes 2 are a first venturi tube 21, a second venturi tube 22 and a third venturi tube 23, respectively, the second venturi tube 22 is located between the first venturi tube 21 and the third venturi tube 23, the first venturi tube 21 is provided with a left gas blocking block 6, the left end of the left gas blocking block 6 is arranged on the left side wall of the first venturi tube 21, the right end of the left gas blocking block 6 is inclined and arranged upwards, the left gas blocking block 6 is located below the gas outlet of the first venturi tube 21, the second venturi tube 22 is horizontally provided with a middle gas blocking block 7, the middle gas blocking block 7 is located below the gas outlet of the second venturi tube 22, the third venturi tube 23 is provided with a right gas blocking block 8, the right end of the right gas blocking block 8 is arranged on the right side wall of the third venturi tube 23, the left end of the right gas barrier block 8 is obliquely and upwards arranged. The left gas blocking block 6 is arranged to prevent the gas in the first venturi tube 21 from directly flowing to the heat dissipation plate 3, but the gas rises along the inclined surface of the left gas blocking block 6 to the right, the middle gas blocking block 7 is arranged to prevent the gas in the second venturi tube 22 from directly flowing to the heat dissipation plate 3, but the gas is divided along the two sides of the middle gas blocking block 7, the right gas blocking block 8 is arranged to prevent the gas in the third venturi tube 23 from directly flowing to the heat dissipation plate 3, but the gas rises along the inclined surface of the right gas blocking block 8 to the left, the left gas blocking block 6, the middle gas blocking block 7 and the right gas blocking block 8 are arranged to enable the gas to gather towards the middle of the heat dissipation plate 3, so that the combustion of the fire row 1 is concentrated, and the direct flushing of the gas out of the heat distribution plate 3 is avoided.
