Referring to fig. 1 and 2, a burner for facilitating air intake includes: a bottom cup 10; the gas distribution disc 20 is arranged on the bottom cup 10, and a gas groove 25 is arranged on the gas distribution disc 20; the air inlet passage 30 is arranged in the bottom cup 10 and communicated to the outside of the bottom cup 10; one of the injection pipe 71 and the opening 72 is arranged on the gas distribution disc 20 and communicated to the inside of the gas groove 25, and the other is arranged on the bottom cup 10 and communicated to the inside of the gas inlet passage 30; the injection pipe 71 is provided with a passage 70, one end of the passage 70 is communicated with the gas groove 25 or the gas inlet passage 30, the other end of the passage 70 is opposite to the opening 72, and a gap 50 communicated with the outside is arranged between the injection pipe 71 and the opening 72. The gap 50 between the ejector pipe 71 and the opening 72 is directly communicated to the outside, so that air can flow into the ejector pipe 71 from the gap 50. Since both the gas flowing out of the opening 72 and the outside air need to enter the passage 70, the air and the gas can be primarily mixed at the gap 50 and then enter the passage 70. The gas and the air are mixed in the injection pipe 71 and are mixed in a large quantity in the gap 50 and then enter the channel 70, so that the air quantity can be effectively increased.

In certain embodiments, referring to FIG. 2, an opening 72 is located on the inlet channel 30, with the nozzle 40 disposed at the opening 72. The nozzle 40 is capable of injecting fuel gas into the passage 70. The nozzle 40 not only enables a directed injection of the gas into the channel 70, but also enables a certain flow rate of the gas. Since there is less air pressure at high flow rates, the outside air will be affected by the air pressure and thus brought into contact with the gas and flow into the channel 70 with the gas.

In some embodiments, there may be a plurality of nozzles 40, such as two, three or more, and a plurality of nozzles 40 may be all located in the inlet 30, or only a portion of the nozzles 40 may be located in the inlet 30.

In some embodiments, referring to fig. 2, the gas distributor 20 is provided with a fire cover 60, and the fire cover 60 blocks the gas groove 25.

In some embodiments, the eductor tube 71 is positioned on the base cup 10 and the passage 70 communicates into the inlet duct 30. The opening 72 is located on the gas distributor 20 and communicates with the gas tank 25. The ejector pipe 71 is located below the opening 72.

In some embodiments, referring to fig. 2, the injection pipe 71 is located on the air distribution plate 20, the opening 72 is located on the air inlet 30, the positioning ring 73 is disposed on the bottom cup 10, and the injection pipe 71 passes through the positioning ring 73 and extends to above the opening 72. The positioning ring 73 can position and fix the ejector pipe 71, thereby preventing the ejector pipe 71 from coming off above the opening 72.

In some embodiments, referring to FIG. 3, the inlet channel 30 is located below the positioning ring 73. The ejector pipe 71 passes through the positioning ring and then directly reaches the upper part of the air inlet passage 30, so as to be opposite to the opening 72.

In some embodiments, referring to FIG. 3, the bottom cup 10 is provided with a flange on which the retaining ring 73 rests; an attachment plate 15 is provided at the edge of the flange, and the end of the attachment plate 15 remote from the flange is connected to the air inlet duct 30. The web 15 enables the air scoop 30 to be located at the edge of the bottom cup 10, and the air scoop 30 is suspended below the retaining ring 73 by the web 15. There is a space below the positioning ring 73, in which there is only the air inlet passage 30, so that the air will be less obstructed in its flow, and thus will flow smoothly in the space.

In some embodiments, referring to fig. 3, the positioning ring 73 is provided with a latch 74 for fixing the injection tube 71. The latch 74 can clamp the injection tube 71, thereby preventing the injection tube from moving in the positioning ring 73.

In some embodiments, referring to FIG. 2, the ejector tube 71 has a leading sidewall that facilitates its insertion into the retaining ring 73. The guide side wall is an inclined side wall which is gradually inclined toward the inside of the injection pipe 71 from top to bottom. The sloped side wall minimizes the cross-sectional area of the lower end of the ejector tube 71 to facilitate its penetration into the retaining ring 73.

In some embodiments, referring to fig. 2, the bottom cup 10 is provided with a connecting groove 82, the gas distribution plate 20 is provided with a connecting column 81, and the connecting column 81 is installed in the connecting groove 82. The matching of the connecting groove 82 and the connecting column 81 enables the air distribution plate 20 and the bottom cup 10 to be relatively fixed. Meanwhile, the connecting column 81 and the injection pipe 71 jointly form a bilateral matching effect, and the air distribution disc 20 and the bottom cup 10 are further fixed, so that the two cannot move relatively.

In some embodiments, the connecting post 81 is located on the base cup 10 and the connecting slot 82 is located on the gas distribution plate.

In some embodiments, the connecting post 81 is located at the rear of the gas distributor plate 20 and the connecting slot 82 is located at the rear of the base cup 10. The injection pipe 71 is positioned at the front part of the air distribution plate 20, and the positioning ring 73 is positioned at the front part of the bottom cup 10. The connecting column 81 and the injection pipe 71 respectively carry out bilateral fixation on the air distribution plate 20 and the bottom cup 10 in the front and back directions, and further effectively prevent the relative sliding of the air distribution plate and the bottom cup.

In some embodiments, the connecting column 81 has a cylindrical structure and the connecting groove 82 has a circular groove structure.

In some embodiments, referring to fig. 3, the base cup 10 is provided with an ignition needle 91 and a safety needle 92. The ignition needle 91 is used to ignite the gas, and the safety needle 92 is used to emergency stop the supply of the gas when the flame is extinguished.

The utility model also provides a gas stove, including the combustor of the air inlet of being convenient for of above arbitrary. The gas and the air are mixed in the injection pipe 71 and are mixed in a large quantity in the gap 50 and then enter the channel 70, so that the air quantity can be effectively increased. Since the amount of air is increased and the air and the gas are primarily mixed at the gap 50, the gas and the air are sufficiently mixed, so that combustion is more sufficient and the generation of yellow flame is prevented.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments or combinations, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
