Burner head, fire grate and gas device

Abstract

A burner head, a fire grate and a gas device are provided. The burner head includes a burner cover and a metal mesh. The burner cover includes a fire partition plate. The fire partition plate is provided with a plurality of fire ports provided at intervals. The fire partition plate is configured to form a partition member between two adjacent fire ports. At least part of the partition member are provided with a first weld position. The metal mesh is provided at the burner cover and is configured to cover the plurality of fire ports. The metal mesh is provided with a first weld spot corresponding to the first weld position. The metal mesh is welded to the first weld position at the first weld spot.

         2 . The burner head according to  claim 1 , wherein:
 the fire partition plate is provided with the plurality of first weld positions along a length direction, wherein the metal mesh is provided with the plurality of first weld spots along the length direction, the first weld spots being welded to the first weld positions one by one; and/or   wherein the first weld position is provided at a middle position in a width direction of the fire partition plate.   
     
     
         3 . The burner head according to  claim 1 , wherein the partition member provided with the first weld position is circular or elliptical. 
     
     
         4 . The burner head according to  claim 1 , wherein:
 the metal mesh is provided with a plurality of layers; and/or   the metal mesh is provided at a surface of the fire partition plate facing away from a counter-fire face of the fire partition plate.   
     
     
         5 . The burner head according to  claim 1 , wherein:
 the fire partition plate comprises a middle region and two end regions respectively provided at both ends of the middle region in a length direction of the fire partition plate; and   an opening area of a single fire port provided at the end region is smaller than an opening area of a single fire port provided at the middle region.   
     
     
         6 . The burner head according to  claim 1 , wherein:
 the fire partition plate is provided with a hollow region; and   the fire partition plate comprises first ribs and second ribs provided in the hollow region, the first rib being intersected with the second rib to divide the hollow region into the plurality of fire ports, and an intersection of the first rib and the second rib forming the partition member.   
     
     
         7 . The burner head according to  claim 6 , wherein:
 the first rib is extended along a width direction of the fire partition plate; and   the second rib is extended along a length direction of the fire partition plate, a plurality of first ribs being provided at intervals along the length direction of the fire partition plate, the second rib being provided between at least two adjacent first ribs.   
     
     
         8 . The burner head according to  claim 7 , wherein:
 the fire partition plate comprises a middle region and two end regions respectively provided at both ends of the middle region in the length direction of the fire partition plate;   a density of the first ribs provided at the middle region is greater than a density of the first ribs provided at the end region; and/or   among the plurality of second ribs provided in the length direction of the fire partition plate, at least two adjacent second ribs in the middle region are provided in a staggered manner in the width direction of the fire partition plate.   
     
     
         9 . The burner head according to  claim 6 , wherein:
 the fire partition plate is provided with cover regions provided at both sides of a length direction of the hollow region; and   the cover region is provided with second weld positions, both ends of the metal mesh being respectively provided with a second weld spot corresponding to the second weld position, the metal mesh being welded to the second weld position by the second weld spots.   
     
     
         10 . The burner head according to  claim 1 , wherein:
 a side edge of the fire partition plate is provided with flanges at a position corresponding to at least part of the fire port; and   a notch is formed between at least part of the flanges and the corresponding side edge of the fire port, wherein part of the side edge of the metal mesh is provided at a bottom side of the flange.   
     
     
         11 . A fire grate comprising:
 a fire grate body, provided with an airflow channel and an air outlet communicated with the airflow channel; and   the burner head according to  claim 1 ,   wherein the burner head is provided at the air outlet.   
     
     
         12 . A gas device comprising the fire grate according to  claim 11 .
