The side wall convex of primary air cavity 13 is equipped with the second location structure 135 (as shown in figure 11).Second positioning knot Structure 135 includes the first support plate 1351 and the second support plate 1352.Wherein, the first support plate 1351 can be arc plate, second Fagging 1352 can be 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 to be removably installed in primary air cavity 13 Side 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 It is that removably, therefore, can match different nozzle carriers 20 according to the demand of upper air inlet and lower air inlet for burner 100, work as spray When mouth seat 20 blocks cavity through-hole 132, burner 100 may be designed to upper inlet wind type burner, when the open cavity through-hole of nozzle carrier 20 When 132, 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 Can be flexible and changeable in the case where low cost, adapt to different use environments.It should be noted that core pulling can be used in nozzle carrier 20 Technique 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 makes nozzle and injection channel 101 coaxial, and be easily installed and prevent with fixed nozzle seat 20 It is slow-witted.Gas injection is injected into injection channel 101 in this way, being conducive to nozzle, ensure that the air velocity of the air inlet in injection channel 101.Peace Loading board 24 is arranged on intake section 21.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 along the airintake direction of intake section 21 Second 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 Setting.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 Column of rule, such as cylindrical or elliptical cylinder-shape etc..In addition, first passage 211 and second channel 212 can pass through mold shape At can guarantee the concentricity in each channel in this way.It should be noted that due to the substantially static pressure of the air-flow in intake section 21, gas Resistance when stream is by the second channel 212 of first passage 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 make first jet and injection channel 101 Relatively.

Specifically, in present embodiment, intake section 21 includes the first air inlet pipe 213 and the second air inlet pipe 214.First air inlet Pipe 213 opens up first passage 211.Second air inlet pipe 214 opens up second channel 212.Such first air inlet pipe 213 and second into Tracheae 214 is arranged in a staggered manner on the thickness direction of burner 100.It may make the first air inlet pipe 213 relative to the second air inlet in this way Pipe 214 is arranged on the lower, to vacate the upper space of nozzle carrier 20, so as to there is sufficient space to carry out plate placement.In addition, second Air inlet pipe 214 can be supported by the first support plate 1351 to position.

First passage 211 is than second channel 212 closer to the inlet end 201 of intake section 21.The cross section of first passage 211 Size is greater than the cross sectional dimensions of second channel 212.For example, if first passage 211 and second channel 212 are rounded, first The radius in channel 211 is greater than the radius of second channel 212；If first passage 211 and second channel 212 are square, first is logical The cross-sectional area in road 211 is greater than the cross-sectional area of second channel 212.Wherein, first passage 211 and second channel 212 Cross section is the section that vertical air inlet direction e is cut.

Intake section 21 is formed with the first positioning surface 210 (as shown in figure 23).The bottom surface of mounting plate 24 is formed with the second positioning Face 241.First positioning surface 210 and the second positioning surface 241 constitute third location structure 23.The side of first support plate 1351 with The engagement of first positioning surface 210.The top surface of second support plate 1352 is engaged with the second positioning surface 241.Wherein, the first positioning surface 210 It can be the positioning surface that the first air inlet pipe 213 and 214 eccentric setting of the second air inlet pipe are formed by step structure.

Incorporated by reference to Figure 21-Figure 23, in order to further increase the stability of the installation of nozzle carrier 20, the quantity of mounting plate 24 is two It is a.Two mounting plates 24 are separately positioned on the opposite two sides of intake section 21.The quantity of second support plate 1352 is two.First Fagging 1351 connects two the second support plates 1352.The top surface of the second support plate of two such 1352 can be installed with two respectively Second positioning surface 241 of plate 24 engages.First support plate 1351 is arc plate, can hold the second air inlet pipe 214.In other words, Second air inlet pipe 214 can be supported and be positioned by the first support plate 1351.

Mounting plate 24 offers the second mounting groove 242.Second mounting hole of the second mounting groove 242 and the second support plate 1352 1353 alignments.Second mounting groove 242 and the second mounting hole 1353 are used for nozzle carrier 20 and bottom cup for fixing piece (not shown go out) 10 fixed use.Wherein, the second mounting groove 242 can be U-type groove.
