Embodiment Construction
[0022] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0023] The gas outlet needle of the gas outlet valve of the lighter as shown in FIG. 2 includes a body 1, and the surface of the body 1 is provided with an antirust electroplating layer. The outer periphery of the body 1 is provided with a spring positioning step 5 and an annular groove 4, and the body 1 is provided with an axial air passage 2, and the body 1 below the spring positioning step 5 is provided with a radial air hole 7, and the radial air hole 7 and the air passage 2 connected. The body 1 is a seamless steel pipe, and the spring positioning step 5 is formed by cold stamping of the seamless steel pipe. The two ends of the air passage are respectively provided with a sealing port 6 and an air-inducing spring installation port 3. The diameter of the sealing port 6 and the air-inducing spring installation port 3 is large...

Abstract
The invention relates to an air outlet valve accessory for a cigarette lighter, in particular to a manufacture method and a device for an air outlet needle of an outlet valve of a cigarette lighter. The invention comprises a body, wherein an axial air flue is arranged in the body, a spring positioning step and a ring groove are arranged on the periphery of the body, and a radial gas hole which isarranged on the upper portion of the body is communicated with the air flue. The body is a seamless steel tube, and the spring positioning step is formed through cold stamping of the seamless steel tube. The body of the invention adopts the seamless steel tube which has a good ductility, and the spring positioning step can be formed through cold stamping of the seamless steel tube, simultaneously, a sealing opening and an air-entraining spring mounting opening which are arranged on the two ends of the air flue can be formed through cold-forging and hole-expanding by the air flue, and the invention has the advantages of low cost and convenient manufacture. The invention further discloses the process for preparing the air outlet needle of an outlet valve of a cigarette lighter and special equipment.
Description
technical field [0001] The invention relates to an accessory of an air outlet valve of a lighter, in particular to an air outlet needle of an air outlet valve of a lighter and a production method and equipment thereof. Background technique [0002] The outlet valve of the lighter, as shown in Figure 1, includes a hollow copper valve body 9, the bottom of the copper valve body 9 is provided with an air inlet hole 12, and there is an air outlet needle in the copper valve body 9, which is movably connected to the copper valve through a copper cap 10. On the body 9, there is an axial air passage 2 in the air outlet needle, and the radial air hole 7 communicates with the axial air passage 2 on the needle wall. A spring 11 is sleeved between the copper caps 10 . The existing air outlet needles are made of copper, and the axial air passage is drilled by a lathe, so not only the cost of materials is high, but also the processing procedure is complicated.
