Abstract

The utility model relates to a burner of a gas furnace. The burner comprises a pedestal, a distributor matched with the pedestal, and a distributor cover matched with the distributor, wherein a gas outlet groove, an ignition groove and a central outlet pipe are arranged on the distributor. The burner is characterized in that a gas mixing cavity, a gas inlet passage communicated with the gas mixing cavity, a bayonet for fixing an ignition needle and a support block protruding upwards are arranged on the pedestal; a location groove is formed on the inner wall of the gas mixing cavity; the central outlet pipe is communicated with the gas mixing cavity; a convex ring is arranged below the distributor cover; at least three convex stages matched with the convex ring for preventing the radial displacement of the distributor cover, a gas guide surface inclined downwards and located around a central gas outlet and a hole where the ignition needle can penetrate are arranged on the distributor; the hole corresponds to the bayonet and the ignition groove; a first support block, a second support block and a third support block capable of being inserted into the location groove are arranged below the distributor; a notch for respectively supporting the second support block and the third support block on the gas mixing cavity are formed on the second support block and the third support block; and the second support block and the third support block can support the pedestal on the gas mixing cavity and form an air inlet gap L. The burner of the gas furnace has the advantages of simple structure, low manufacturing cost, automatic air compensation, high burning efficiency, and so on.

Description

The burner of gas furnace

Technical field

The utility model relates to a kind of burner of gas furnace.

Prior art

The burner structure more complicated of existing gas furnace, the production cost height, air can not well replenish, and efficiency of combustion is not high.

The utility model content

The utility model is to overcome the deficiencies in the prior art and provide a kind of simple in structure, and production cost is low, can well replenish air, the burner of a kind of gas furnace that efficiency of combustion is high automatically.

In order to achieve the above object, the utility model is to realize like this, it is a kind of burner of gas furnace, distributor that comprises base, matches with base and the Fen Huogai that matches with distributor, on distributor, be provided with the groove of giving vent to anger, ignition slot and center escape pipe, it is characterized in that: on base, be provided with mixed air cavity, the inlet channel that communicates with mixed air cavity, make the bayonet socket of igniting pin location and the back-up block that raises up, be provided with a location groove at the inwall that mixes air cavity, the center escape pipe is communicated with mixed air cavity; Below Fen Huogai, be provided with bulge loop, at the boss that prevents branch fire lid radial displacement that cooperates with bulge loop that is provided with on the distributor more than three; On distributor, be positioned at the gas outlet, center around be provided with downward-sloping air guide face and the hole that can pass of igniting pin, the position in this hole is corresponding with the position of the position of bayonet socket and ignition slot, below distributor, be provided with first back-up block, second back-up block and the 3rd back-up block that can insert detent, be respectively equipped with the breach that its support can be mixed on the air cavity on second and third back-up block, second and third back-up block and back-up block make distributor be supported on the mixed air cavity of base and produce the gap L of air inlet.

On described mixed air cavity inwall, be respectively equipped with first convex tendon, second convex tendon and the 3rd convex tendon that prevent distributor and radially rotate; First convex tendon is positioned at the below of described detent, and it supports described first back-up block, and second convex tendon cooperates with described second back-up block, and the 3rd convex tendon cooperates with described the 3rd back-up block.

The utility model advantage compared with prior art is that simple in structure, production cost is low, can well replenish air, efficiency of combustion height automatically.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is done further detailed description:

Shown in Fig. 1 to 6, it is a kind of burner of gas furnace, distributor 2 that comprises base 3, matches with base and the branch fire lid 1 that matches with distributor, on distributor, be provided with the groove 23 of giving vent to anger, ignition slot 25 and center escape pipe 22, characteristics of the present utility model are: be provided with and mix air cavity 35, the inlet channel 34 that communicates with mixed air cavity, make the bayonet socket 32 of igniting pin location and the back-up block 31 that raises up on base 3, be provided with a location groove 38 at the inwall that mixes air cavity, center escape pipe 22 is communicated with mixed air cavity 35; Below Fen Huogai 1, be provided with bulge loop 11, at the boss 24 that prevents branch fire lid radial displacement that cooperates with bulge loop that is provided with on the distributor 2 more than three; On distributor, be positioned at the downward-sloping air guide face 21 that is provided with of center escape pipe 22 and the hole 29 that the igniting pin can pass on every side, the position in this hole is corresponding with the position of the position of bayonet socket and ignition slot, below distributor, be provided with first back-up block 27, second back-up block 26 and the 3rd back-up block 28 that can insert detent, be respectively equipped with the breach 261,281 that its support can be mixed on air cavity 35 walls on second and third back-up block, second and third back-up block and back-up block make distributor 2 be supported on the mixed air cavity of base and produce the gap L of air inlet.During use, combustion gas enters from inlet channel 34 and mixes the air cavity 35, air enters from gap L and flows out from center escape pipe 22 after mixing air cavity and combustion gas being mixed again, under the effect of air guide face 21, mixed combustion gas from give vent to anger groove 23 ejections also quilt is lighted generation flame.
