Roof 111 offers gas outlet 114.Injection channel 101 is connected to gas outlet 114 by interface channel 102.In this way by
The gaseous mixture of combustion gas and air that 101 injection of injection channel goes out can be supplied to flame projector 30 by gas outlet 114 for burning.
In order to make burner 100 be capable of forming polycyclic flame, gas outlet 114 includes outer ring gas outlet 1141 and inner ring outlet
Mouth 1142.The outlet side and outer ring gas outlet 1141 in the first interface channel 1021 connection injection channel 101.Go out to increase outer ring
Arc-shaped shape is arranged in the outlet area of port 1141 and the uniformity for guaranteeing outlet, outer ring gas outlet 1141, such as arc-shaped, outside
The center of circle where ring gas outlet 1141 is Chong Die with the second center y of primary air cavity 13.In addition, outer ring gas outlet 1141
It is protruded respectively by the top surface 1110 of roof 111 with inner ring gas outlet 1142.
Incorporated by reference to Figure 16, in order to keep the outlet of outer ring gas outlet 1141 more uniform, outer ring gas outlet 1141 includes interval
The the first outer ring gas outlet 1143 and the second outer ring gas outlet 1144 being arranged.First interface channel 1021 includes that the first son connection is logical
Road 10211 and the second sub- interface channel 10212.First sub- interface channel 10211 and the second sub- interface channel 10212 are separately connected
In the outlet side two sides in injection channel 101.First sub- interface channel 10211 is connected to the first outer ring gas outlet 1143 and injection channel
101.Second sub- interface channel 10212 is connected to the second outer ring gas outlet 1144 and injection channel 101.Wherein, the first son connection is logical
Road 10211 and the second sub- interface channel 10212 can be arc-shaped, and can connect the first sub- interface channel 10211 and the second son
Connection road 10212 is arranged to symmetrical about the central axis in the injection channel 101 of bottom cup 10.In order to reduce the resistance of air-flow flowing
Power can be such that the first sub- interface channel 10211 connect with the outlet side cambered surface in injection channel 101, and make the second sub- interface channel
10212 connect with the outlet side cambered surface in injection channel 101.
Incorporated by reference to Figure 16, in order to keep the outlet of inner ring gas outlet 1142 more uniform, inner ring gas outlet 1142 includes interval
The the first inner ring gas outlet 1145 and the second inner ring gas outlet 1146 being arranged.Second interface channel 1022 includes that the connection of third is logical
Road 10221 and the 4th sub- interface channel 10222.The sub- interface channel 10221 of third is connected to the first sub- interface channel 10211 and first

Incorporated by reference to Figure 11-Figure 21, primary air cavity 13 offers the primary air chamber 131 in connection injection channel 101.One
The side wall of secondary air chamber 131 offers the cavity through-hole 132 of connection primary air chamber 131.Specifically, primary air cavity 13 wraps
Include annular element 133 and cavity body 134.Annular element 133 is protruded by the side of bottom cup lid body 11.Annular element 133 has opening
1331.Cavity body 134 is protruded by the side of bottom cup holder body 12.Annular element 133 is sheathed on the roof of cavity body 134 and common
Form primary air chamber 131.1331 connection primary air chamber 131 of opening.The side wall of cavity body 134 opens up cavity through-hole 132.
Air can be entered in primary air chamber 131 by cavity through-hole 132 and/or opening 1331.Wherein, the flat shape of annular element 133
Arc-shaped shape.
For the ease of fixed and positioned, annular element 133 offers first positioning hole 1332 (as shown in figure 17).Cavity body
134 roof is convexly equipped with positioning column 1341 (as shown in figure 14).Positioning column 1341 is fixed in first positioning hole 1332 bottom of at
Cup lid body 11 and bottom cup holder body 12 play the role of positioning and fixation during combining.
The side wall convex of primary air cavity 13 is equipped with the second location structure 135 (as shown in figure 12).Second positioning knot
Structure 135 includes the first support plate 1351 and the second support plate 1352.Wherein, the first support plate 1351 is arc plate, the second support
Plate 1352 is plate.Second support plate 1352 offers the second mounting hole 1353.
In order to facilitate the maintenance and maintenance of nozzle carrier 20, nozzle carrier 20 is removably installed in the side of primary air cavity 13
Wall.Nozzle carrier 20 is located at cavity through-hole 132 and is configured to block or open cavity through-hole 132.Due to nozzle carrier 20 be can
Demolition, therefore, different nozzle carriers 20 can be matched for burner 100, works as nozzle carrier according to the demand of upper air inlet and lower air inlet
20 when blocking cavity through-hole 132, and burner 100 may be designed to upper inlet wind type burner, when the open cavity through-hole 132 of nozzle carrier 20
When, burner 100 may be designed to lower air inlet burner, or enter the wind burner up and down.Therefore, the air inlet mode of burner 100 exists
Can be flexible and changeable in the case where low cost, adapt to different use environments.It should be noted that core pulling work can be used in nozzle carrier 20
Skill manufacture.
Incorporated by reference to Figure 22 and Figure 23, nozzle carrier 20 includes intake section 21, baffle 22, third location structure 23 and mounting plate
24.22 projection of baffle is on intake section 21.The height of baffle 22 is adjustable so that baffle 22 blocks or open cavity through-hole
132.When baffle 22 blocks cavity through-hole 132, baffle 22 fills cavity through-hole 132.It is logical convenient for blocking or opening cavity in this way
Hole 132.Second location structure 135 connects from third location structure 23 and limits nozzle carrier jointly from least two different directions
20 position on bottom cup 10 with fixed nozzle seat 20, and is easily installed and fool proof.Mounting plate 24 is arranged in intake section 21
On.Wherein, preferably, at least two above-mentioned directions include orthogonal both direction.
It is appreciated that in other embodiments, baffle can also directly overlay the side wall appearance of primary air chamber 131
Face can also realize that baffle blocks cavity through-hole 132 in this way.In addition, in other embodiments, nozzle carrier can omit baffle,
The lower burner entered the wind can be achieved, in this case, it is understood that be that the height of baffle is zero.
Incorporated by reference to Fig. 3 and Fig. 7, in order to make full use of installation space, keep 100 overall structure of burner more compact, intake section
21 offer along airintake direction e (as shown in Figure 7) first passage 211 being sequentially communicated and second channel 212.First passage 211
Airintake direction along intake section 21 has the first air inlet central axis z.Second channel 212 has the along the airintake direction of intake section 21
Two air inlet central axis g.First air inlet central axis z and the second air inlet central axis g are staggered on the thickness direction of burner 100 and set
It sets.The thickness direction of burner 100 is the up and down direction in Fig. 7.Wherein, first passage 211 and second channel 212 can be in rules
Column, such as cylindrical or elliptical cylinder-shape etc..In addition, first passage 211 and second channel 212 can be formed by mold, this
Sample can guarantee the concentricity in each channel.It should be noted that air-flow is by due to the substantially static pressure of the air-flow in intake section 21
Resistance when the mistake second channel 212 of one channel 211 can be smaller.Wherein, primary air chamber 131 is connected to second channel 212.In addition,
First jet (not shown go out) can be installed in the gas outlet of second channel 212, and keep first jet and injection channel 101 opposite.
Specifically, in present embodiment, intake section 21 includes the first air inlet pipe 213 and the second air inlet pipe 214.First air inlet
