Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model will be further described. It should be noted here that the descriptions of these implementations are used to help understand the utility model, but are not intended to limit the utility model. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute conflicts with each other.

As shown in Figures 1 to 12, it is an air outlet assembly of an ignition gun, including a surface valve air outlet needle 1, a rubber hose 2 and a fire nozzle 3, and the air inlet end of the surface valve air outlet needle 1 communicates with the ignition gun air box , the outlet end of the surface valve air outlet needle 1 is inserted in one end of the rubber hose 2, the inlet end of the fire outlet 3 is inserted in the other end of the rubber hose 2, and the outlet end of the fire nozzle 3 communicates with the outside world; The air outlet end of the air outlet needle 1 is provided with an air outlet needle guide head 11, the air outlet needle guide head 11 is located in the rubber tube 2, and two air outlet side holes 12 are opened on the side wall of the air outlet needle guide head 11, the air outlet The side hole 12 communicates with the rubber hose 2; the gas outlet side hole 12 can be one, two, three or several, depending on the actual situation; the gas in the gas box of the ignition gun is discharged to the rubber hose through the gas outlet side hole 12 2, because the gas outlet side hole 12 is set on the side wall of the gas outlet needle guide head 11, the gas outflow speed in the ignition gun gas box is slowed down, the internal pressure of the rubber hose 2 is reduced, the gas flow rate is appropriate, and the internal pressure of the rubber hose is appropriate , The ignition gun will not emit fire, and it is safe to use; the air outlet needle guide head 11 is easy to align with the inner hole at one end of the rubber hose 2, and the assembly is convenient.

In this embodiment, a fire nozzle guide head 31 is provided on the air inlet end of the fire nozzle 3, and the fire nozzle guide head 31 is located in the rubber tube 2, and a fire nozzle guide head 31 is provided on the side wall of the fire nozzle guide head 31. There are two inlet side holes 32, and the inlet side holes 32 communicate with the rubber hose 2; the inlet side holes 32 can be one, two, three or several, depending on the actual situation; the rubber hose 2 The gas inside enters the fire nozzle 3 through the air inlet side hole 32. Since the air inlet side hole 32 is set on the side wall of the fire nozzle guide head 31, the gas flow rate in the rubber tube 2 has been further slowed down, and the outlet nozzle 3 The ejected gas can be better mixed with the air, the ignition gun will not emit flames, and the gas burns completely, which is safe to use. The nozzle guide head 31 is easy to align with the inner hole at the other end of the rubber hose 2, and the assembly is convenient.

In this embodiment, the air outlet needle guide head 11 is in the shape of a circular truncated cone, and the size of the upper end surface of the air outlet needle guide head 11 is smaller than the size of the lower end surface. Because the gas outlet needle guide head 11 is in the shape of a circular platform, the gas flows out from the gas outlet side hole 12 better, further reducing the flow rate of the gas and reducing the pressure of the rubber hose; the assembly of the gas outlet needle 1 and the rubber hose 2 of the instant noodle valve.

In this embodiment, the nozzle guide head 31 is in the shape of a rounded table. The size of the lower surface of the nozzle guide head 31 is smaller than the size of the upper surface of the nozzle guide head 31 . Since the guide head 31 of the nozzle is in the shape of a rounded table, the gas enters the nozzle 3 from the side of the rubber tube 2 better, further reducing the gas flow rate, and the ignition gun will not burst into flames, and the gas will burn completely, which is safe to use ; Facilitate the assembly of the nozzle 3 and the hose 2.

In this embodiment, the air outlet side hole 12 is flared. The size of the air outlet of the air outlet side hole 12 is greater than the size of the air inlet of the air outlet side hole 12 . Since the gas outlet side hole 12 is flared, the gas flow rate slows down, and the pressure of the rubber hose 2 decreases.

In this embodiment, the air inlet side hole 32 is flared. The size of the air inlet of the air inlet side hole 32 is greater than the size of the air outlet of the air inlet side hole 32 . Because the air inlet side hole 32 is flared, the gas and air can be better mixed at the gas outlet of the fire nozzle 3, the combustion efficiency is high, and the phenomenon of flame spraying will not occur.

The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and deformations to these embodiments without departing from the principle and purpose of the present invention still fall within the protection scope of the present invention.
