Description

Lighter Technical Field The invention relates to the technical field of fire taking equipment, in particular to a lighter. Background The lighter can be used for cooking and other fire taking, the main components of the lighter in the prior art are a firing mechanism and a fuel cylinder, an air valve is arranged on the fuel cylinder, the firing mechanism comprises a lever pressing plate, a pressing piece, a flint and a firing wheel, the firing wheel is rotated by thumb pulling to drive the friction wheel to rotate so as to rub the flint to give out sparks, meanwhile, the thumb makes the lever pressing plate turn up by pressing the pressing piece, and the air valve exhausts so as to enable the sparks to ignite gas. The existing steel wheel lighter has the defects that the flame root is maintained only by virtue of a weak negative pressure area at the edge of the air outlet hole in a linear air injection mode, the flame stability is insufficient, the windproof effect is poor, the air outlet hole is in an exposed state based on the outside, the phenomenon of foreign matter entering easily occurs, the phenomenon of unsmooth gas injection or incapability of gas injection is caused, and the using effect is influenced. Disclosure of Invention The present invention is directed to a lighter for solving the above-mentioned problems. The invention provides a lighter which comprises a lighter body, wherein the top of the lighter body is provided with air outlet holes, the cross section of a fan cover is U-shaped and is arranged on the lighter body, a flow guide piece is arranged outside the air outlet holes, the flow guide piece comprises a lantern ring and at least one spiral blade, the lantern ring is arranged on the inner side of the fan cover, the spiral blades are arranged above the air outlet holes in a vertical mode, and the spiral blades are fixedly connected to the inner side of the lantern ring. Preferably, the air guide piece further comprises a guide column fixedly connected to the machine body, the air outlet hole is located on the inner side of the machine body, the bottom of the air outlet hole is provided with a guide groove, the guide groove is horn-shaped, and one side of the lantern ring is fixedly connected to the upper portion of the guide ring. Preferably, the top of the flow guiding column is provided with a through groove, the through groove is communicated with the flow guiding groove, and the inner diameter of the through groove is smaller than the inner diameters of the lantern ring and the air outlet hole. Preferably, a collecting groove is formed in the top of the flow guiding column, and the collecting groove is annular. Preferably, the material of the guide post is copper. Preferably, the two spiral blades are staggered along the axis of the spiral blade. Preferably, the spiral blade comprises a base plate, the diameter of the base plate is larger than the inner diameter of the through groove, a plurality of guide vanes are distributed annularly and are obliquely arranged, and the guide vanes are fixedly connected to the outer side of the base plate. Compared with the prior art, the invention has the following beneficial effects: according to the invention, the lantern ring and the helical blades are arranged, and the lantern ring is matched with the fan housing to form double protection, so that the stability of flame root systems is ensured, and after fuel gas is sprayed, the flame is influenced by the diversion of the helical blades to form a helical flow mode, so that the stability of fuel gas in flowing is ensured, and the flame stability and the windproof effect are improved; Through setting up collecting vat, base plate and two crisscross helical blade, can shelter from the protection to the venthole top, after the foreign matter gets into the cover intra-annular, the collocation collecting vat carries out the foreign matter and collects, reduces the phenomenon emergence that the foreign matter got into the venthole, guarantees gas injection effect and subsequent result of use.
