According to the windproof cooker support, when gas is combusted, air around the gas cooker can supply oxygen required by combustion to the gas cooker through the ventilation opening 11, so that incomplete combustion of the gas is prevented, the gas is saved, and meanwhile, the generation of harmful gas is avoided. When no wind exists around the gas stove or the wind power is smaller, the shielding degree of the wind shielding structure 2 to the ventilation opening 11 is relatively smaller, and the air around the gas stove can supply oxygen required by combustion to the gas stove through the ventilation opening 11; when wind power around the gas-cooker is great, the shielding degree of the wind shielding structure 2 to the vent 11 can be correspondingly increased according to the received wind power, the wind is prevented from blowing off the flame of the gas-cooker through the vent 11, the air flow speed near the vent 11 is fast at the moment, the air around the gas-cooker can still normally supply oxygen required by combustion to the gas-cooker through the vent 11, and the gas can be completely combusted.
Specifically, the bracket frame 1 may be a circular frame or a square frame. Preferably, the bracket frame 1 is a square frame with rounded corners.
It should be noted that, the windproof cooker support of the invention is generally arranged on the burner of the gas stove, the support frame body 1 surrounds the burner of the gas stove to eliminate the adverse effect of wind around the gas stove on the gas stove, and the wind shielding structure 2 and the reset mechanism 3 can reasonably utilize part of wind to promote the air supply to the gas stove while eliminating the adverse effect of wind around the gas stove on the gas stove.
In some embodiments of the present invention, as shown in fig. 3 and 4, the wind shielding structure 2 includes a swing assembly 21 rotatably connected to the bracket frame 1, the swing assembly 21 can shield or open the ventilation opening 11, and the reset structure 3 is connected to the swing assembly 21 so that the swing assembly 21 can change the shielding degree of the ventilation opening 11 according to the actual wind force.
Specifically, when the swing assembly 21 is acted on by wind force, the swing assembly 21 swings towards the ventilation opening 11 to increase the shielding degree of the ventilation opening 11, and part of the wind is shunted into the ventilation opening 11 after being blocked by the swing assembly 21, but the strength of the shunts passing through the swing assembly 21 is insufficient for blowing out the flame of the gas stove, and the air flow near the ventilation opening 11 can be promoted, so that the oxygen required by the gas stove for supplementing the gas combustion is facilitated. The reset structure 3 can hinder but not prevent the swinging assembly 21 from swinging towards the ventilation opening 11 when the swinging assembly 21 swings towards the ventilation opening 11, and when the wind force around the gas stove is reduced, the reset structure 3 can drive the swinging assembly 21 to swing towards the initial position before the swinging is started, in particular, when the wind around the gas stove stops, the reset structure 3 can drive the swinging assembly 21 to return to the initial position before the swinging is started.
