DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-4 The utility model is described in further detail.

[0023] The utility model discloses a highly efficient, energy-saving and safe gas ignition gun nozzle unit. Figure 1-2, including a nozzle body 1 and a gas supply mechanism, the nozzle body 1 is the flamethrower barrel of an existing gas ignition gun.

[0024] Reference Figure 1-2 An igniter 11 for ignition is fixed at one end of the nozzle body 1, and a gun head 12 for spraying flames is provided at the other end of the nozzle body 1. The igniter 11 can ignite the gas mixed with air in the nozzle body 1, and the flame in the nozzle body 1 will be sprayed out through the gun head 12. The nozzle body 1, the igniter 11 and the gun head 12 constitute the nozzle structure of the existing gas ignition gun.

[0025] Reference Figure 1-2 A metal bellows 13 is fixed between the nozzle body 1 and the gun head 12. The metal bellows 13 can connect the nozzle body 1 and the gun head 12, and the metal bellows 13 can provide space for the gun head 12 to rotate by its own deformation.

[0026] Reference Figure 1-2 A gooseneck 14 is fixed between the nozzle body 1 and the outer wall of the gun head 12 for adjusting the flame spraying angle of the gun head 12. Insulation materials such as insulation pads can be set at the connections between the two ends of the gooseneck 14 and the nozzle body 1 and the gun head 12. After the staff manually turns the gooseneck 14, the angle and direction of the gun head 12 can be changed, which makes it easier for the gun head 12 to spray flames at different positions. It is suitable for various usage scenarios. The gooseneck 14 is a metal shaped hose, which is an existing metal part that can be bent arbitrarily and determine the direction.

[0027] Reference Figure 1-2 The gas supply mechanism includes a gas connecting pipe 2 provided on one side of the nozzle body 1, an air connecting pipe 21 fixedly provided at one end of the gas connecting pipe 2, and a mixing pipe 22 fixedly provided between the nozzle body 1 and the gas connecting pipe 2. The gas connecting pipe 2 can be connected to an external gas pipe, and the air connecting pipe 21 can be connected to an air pipe for supplying air from the outside. The gas and air respectively supplied by the gas connecting pipe 2 and the air connecting pipe 21 can be mixed in the mixing pipe 22.

[0028] Reference Figure 1-2 A safety protection mechanism is provided on the nozzle body 1 and the gas connecting pipe 2. The safety protection mechanism includes a combustion temperature sensor 4 fixedly installed on one side of the nozzle body 1 for real-time monitoring of the combustion temperature, and a gas flow controller 41 fixedly installed on the end of the gas connecting pipe 2 away from the air connecting pipe 21 for monitoring the gas flow. The combustion temperature sensor 4 and the gas flow controller 41 are both existing equipment, and their internal structures and circuit connections are public technologies, which will not be elaborated here.

[0029] Reference Figure 2-4A mixing mechanism is provided in the mixing tube 22, and the mixing mechanism includes a spiral blade 3 fixed in one end of the mixing tube 22 near the gas connecting tube 2 for premixing the gas and air, a block 34 fixed in the other end of the mixing tube 22, and a plurality of micro-channels 35 opened in the block 34 for further mixing the gas and air. The spiral blade 3 can premix the gas and air entering the mixing tube 22 through its own spiral channel, and the block 34 can seal one end of the mixing tube 22 so that the gas in the mixing tube 22 will flow in the plurality of micro-channels 35.

[0030] Reference Figure 3 A fixing rod 31 is fixed inside the spiral blade 3, and a baffle 32 is fixed at one end of the fixing rod 31. The baffle 32 is fixedly connected to the inner wall of the mixing tube 22. The baffle 32 is located between the spiral blade 3 and the block 34. The fixing rod 31 can block the middle part of the spiral blade 3 to form a spiral channel. The baffle 32 and the fixing rod 31 can further support the spiral blade 3.

[0031] Reference Figure 3 A plurality of tapered holes 33 are provided in the baffle 32, whose apertures gradually decrease along the direction from the spiral blade 3 to the block 34. The gas and air premixed by the spiral blade 3 can flow to the micro-channels 35 through the tapered holes 33. Since the apertures of the tapered holes 33 gradually decrease along the gas flow direction, according to the Bernoulli principle, the flow rate of the gas and air through the baffle 32 can be accelerated, so that the gas and air are closer together, thereby promoting further mixing of the gas and air.

[0032] Reference Figure 2-4 A plurality of first arc blocks 36 are fixed on one side of the micro-channel 35, and a plurality of second arc blocks 37 are fixed on the other side of the micro-channel 35, which are staggered with the plurality of first arc blocks 36 in sequence. The sum of the widths of the first arc blocks 36 and the second arc blocks 37 is greater than the width of the micro-channel 35. Through the staggered blocking of the first arc blocks 36 and the second arc blocks 37 in the micro-channel 35 and the guidance of the arc surfaces of the first arc blocks 36 and the second arc blocks 37, the gas and air can collide with each other and mix again, so as to optimize the mixing ratio of the gas and air, make the gas and air evenly mixed, and improve the combustion efficiency.

[0033] The implementation principle of the efficient, energy-saving and safe gas ignition gun nozzle unit of the embodiment of the utility model is:

[0034] When in use, the gas connecting pipe 2 can be connected to an external gas pipe, and the air connecting pipe 21 can be connected to an air pipe for supplying air from the outside. The gas and air supplied by the gas connecting pipe 2 and the air connecting pipe 21 respectively enter the mixing pipe 22. At this time, the spiral blade 3 can premix the gas and air entering the mixing pipe 22 through its own spiral channel.

[0035] The premixed gas and air from the spiral blades 3 then flow through the tapered holes 33 to the micro-channels 35. As the diameter of the tapered holes 33 gradually decreases along the direction of gas flow, the Bernoulli principle accelerates the flow of gas and air through the baffle 32, creating a closer bond between the gas and air, thereby promoting further mixing of the gas and air.

[0036] The further mixed gas and air then enter the multiple micro-channels 35 under the blocking of the blocking block 34. The staggered blocking of the first curved block 36 and the second curved block 37 in the micro-channel 35, combined with the guidance of the curved surfaces of the first curved block 36 and the second curved block 37, can cause the gas and air to collide with each other and mix again, thereby optimizing the mixing ratio of the gas and air and making the gas and air evenly mixed, thereby improving the subsequent combustion efficiency and being more efficient and energy-saving.

[0037] After mixing, the gas mixed with air will flow into the nozzle body 1, and the igniter 11 can ignite the gas mixed with air in the nozzle body 1. The flame in the nozzle body 1 will be ejected through the gun head 12. When the angle of the gun head 12 needs to be adjusted, the staff can manually turn the gooseneck 14 to change the angle and direction of the gun head 12, so that the gun head 12 can spray fire at different positions, which is suitable for various usage scenarios.

[0038] Furthermore, by providing the combustion temperature sensor 4 and the gas flow controller 41 , the combustion temperature and gas flow can be monitored in real time to ensure safe use.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
