Problems solved by technology

Although the appearance of this adjustment-free lighter outlet valve solves the problem of no adjustment, it still needs to be linked with the ignition button by setting springboards and other parts to open the airway during use, just like the traditional outlet valve. , resulting in a very complex structure of the lighter, and a corresponding increase in the difficulty of making injection molds, and the way that the adjustment-free gas valve assembly is installed on the gas tank through threads is not conducive to automatic production, resulting in high production costs for the whole machine

Abstract

The invention relates to an adjustment-free downward pressing type lighter gas outlet valve. The adjustment-free downward pressing type lighter gas outlet valve comprises an adjustment-free gas valve assembly and a sealing ring. The adjustment-free gas valve assembly comprises a valve needle, a valve body and a gas filtering film. According to the adjustment-free downward pressing type lighter gas outlet valve, the adjustment-free purpose is achieved by arranging the gas filtering film at the bottom of an inner cavity of the valve body to control the gas outlet flow; meanwhile, the lower end of the valve body is sleeved with a pressing spring, a sealing pressing ring and the sealing ring sequentially, the sealing ring is close to a transverse hole and is located below the transverse hole, an inner hole of the sealing ring is in sealing fit with the outer wall of the valve body, the lower end of the pressing spring elastically abuts against the sealing pressing ring, the upper end of the pressing spring elastically abuts against the outer wall of the valve body, and a center hole of the sealing pressing ring is in clearance fit with the valve body; when the adjustment-free downward pressing type lighter gas outlet valve is used, the lower end of the valve body is inserted at a gas outlet of a gas tank, an ignition button is directly connected with the lower pressing surface of the adjustment-free gas valve assembly through a piezoelectron, and a springboard and the like do not need to be arranged; and during ignition, the adjustment-free gas valve assembly overcomes the elastic force of the pressing spring and is downwards pressed, the transverse hole downwards moves to the position below the sealing ring, gas in the gas tank can enter the valve body through the transverse hole and overflow from the valve needle, and ignition is completed.

Description

technical field [0001] The invention relates to parts of a lighter, in particular to an adjustment-free downward-pressing type lighter gas outlet valve. Background technique [0002] Disposable open flame lighters with non-adjustable lighter outlet valves do not need to be inflated to adjust the flame height when leaving the factory, and the products are easy to meet the requirements for flame height and stability of open flame lighters in Europe and the United States. Therefore, they are more and more popular among manufacturers, and the output is year by year Increase. At present, the outlet valve of an adjustment-free lighter usually includes two parts: an outlet valve and an adjustment-free flow limiting device. The outlet valve includes a valve needle, a sealing ring, a valve body, and a valve seat. The side is provided with an air intake horizontal hole connected to the central hole. The valve body is opposite to the open end of the valve seat and connected in a close...
