Because nozzle 3 is arranged on the side wall of gas transmission mixing tube 2, and the one of gas transmission mixing tube 2 is arranged in blower chamber 4
End, the combustion gas of gas transmission mixing tube 2 is entered from nozzle 3, first from the second through-hole 512 enter gas mixing component 5 in, and with from
After air (being entered in gas transmission mixing tube 2 by 4 injection of the blower chamber) mixing that first through hole 511 enters, becomes pre-mixing gas combustion, premix
Combustion gas enters in burner 1 after gas transmission mixing tube 2 under the action of blower chamber 4；
In the present embodiment, the axis of nozzle 3 and the axis of blower chamber 4 are mutually perpendicular to, this is ensured flows out from nozzle 3
Combustion gas initial flow route, the initial flow route with the air entered in gas transmission mixing tube 2 from blower chamber 4 is phase
It is mutually vertical, it is ensured that combustion gas can be sufficiently mixed with air in gas mixing component 5；
Because combustion gas and air are to enter in gas mixing component 5 from two mutually orthogonal directions, and metal mesh 51 is right
Combustion gas and air also function to certain inhibition, avoid combustion gas and air from flowing in gas mixing component 5 too fast, and cause
Combustion gas and air cannot be sufficiently mixed；And first through hole 511 and the second through-hole 512 can ensure that combustion gas and air can be smooth
Eluting gas electric hybrid module 5, and can ensure combustion gas and the mixing of air, so combustion gas and air are in gas mixing component 5
It can adequately mix, it is ensured that there is sufficient air from the pre-mixing gas combustion flowed out in gas mixing component 5, be able to solve big
Combustion gas existing for gas formula burner, which mixes with air, to be not enough, and is burnt in caused combustion process insufficient, the thermal efficiency is low
Problem.
In the present embodiment, gas mixing component 5 includes 30 metal meshes 51, is provided on each metal mesh 51 multiple
First through hole 511, adjacent two metal meshes 51 connection form the second through-hole 512 being connected to first through hole 511；

The quantity of first through hole 511 on each metal mesh 51 is also determined that quantity is can ensure combustion gas and air by actual conditions
It can be sufficiently mixed as principle.
In a particular embodiment, blower chamber 4 includes air blower 41 and fan seat 42, fan seat 42 and gas transmission mixing tube 2
Connection, air blower 41 is arranged on fan seat 42, and air blower 41 connects to power supply；
When energized, air blower 41 rotates, and the air outside gas transmission mixing tube 2 can be introduced into gas transmission mixing tube 2, and
After being mixed in gas mixing component 5 with combustion gas, then through the entrance burner 1 of gas transmission mixing tube 2, it is ensured that enter gas mixing
Air in component 5 is enough.
In a particular embodiment, burner 1 includes stove top 11 and premixed gas storage room 12,12 side of premixed gas storage room
Gas transmission mixing tube 2 is provided on wall, and the upper end cover of premixed gas storage room 12 is equipped with stove top 11；Because premixed gas stores
It is provided with gas transmission mixing tube 2 on 12 side wall of room, and is connected to gas transmission mixing tube 2, so air and combustion gas are in gas mixing component 5
After interior mixing, enter in premixed gas storage room 12 through gas transmission mixing tube 2, and then flowed to outside burner 1 from stove top 11, if through
It crosses and lights, then pre-mixing gas combustion burns on stove top 11.
In a particular embodiment, nozzle 3 is vertically set on 2 side wall of gas transmission mixing tube and between gas mixing component 5
Form gas circulation gap, in order to ensure the combustion gas entered in gas mixing component 5 from nozzle 3, enter gas
Before electric hybrid module 5, first it is diffused, so as to it is more uniform, it more easily enters in gas mixing component 5 and is carried out with air
Mixing.
In a particular embodiment, the length L of gas mixing component 52Meet: 30d < L2< 50d；Purpose be to ensure that combustion gas with

In the present embodiment, the diameter d of nozzle 3 meets: d=1mm, the length L of gas mixing component 52=50mm, gas
Electric hybrid module 5 is cylindrical structure, maximum gauge 30mm；
The depth h in gas circulation gap1=7mm, L1=30mm；
In a particular embodiment, there are air passing clearances between blower chamber 4 and gas mixing component 5, it is therefore an objective to be
The air that ensures to enter from blower chamber 4 in gas mixing component 5 is first expanded before entering gas mixing component 5
It dissipates, so as to it is more uniform, it more easily enters and is mixed in gas mixing component 5 with combustion gas.
In a particular embodiment, the depth h of air passing clearances2Meet: 30mm < h2< 100mm, in order to ensure
Air can sufficiently be spread before entering gas mixing component 5, and then be ensured after entering gas mixing component 5, can be abundant
With combustion gas mixing.
In the present embodiment, the depth h of air passing clearances2=30mm.
Specific work process are as follows:
Air blower 41 operate, the air ejection outside gas transmission mixing tube 2 is entered into air passing clearances, air passing clearances into
After row diffusion, enter in gas mixing component 5 from first through hole 511, while combustion gas enters gas circulation gap from nozzle 3,
After being diffused in gas circulation gap, enter in gas mixing component 5 from the second through-hole 512；Enter gas mixing group
Combustion gas and air in part 5 also have dredging since gas mixing component 5 not only has the function of obstruction to air and combustion gas
Effect, obstruction is to prevent air and the too fast flowing of combustion gas, it is ensured that air and combustion gas can be in gas mixing components 5
It is sufficiently mixed；Dredging be in order to ensure air and combustion gas and air and the mixed premixed gas of combustion gas can smoothly from
Outflow, flows in gas transmission mixing tube 2, and flow in premixed gas mixing chamber 12 through gas transmission mixing tube 2 in gas mixing component 5,
And then it burns on stove top 11；Because air and combustion gas are entered in gas mixing component 5 from two mutually orthogonal directions,
And by prolonged mixing in gas mixing component 5, the pre-mixing gas combustion flowed out from gas mixing component 5 is able to solve at present
Combustion gas existing for traditional air suspended type mixing burner, which mixes with air, to be not enough, and is burnt and is not filled in caused combustion process
Point, the low problem of the thermal efficiency.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with scope of protection of the claims
