Abstract

The invention relates to a tuyere tip for both an American tuyere and a French tuyere, comprising a shell body with a body part, wherein a shaft hole is disposed in the middle of the body part; a rotary piece held in the shaft hole of the body part of the shell body and capable of rotating, wherein the both ends of the rotary piece project out of the shaft hole of the body part to form head parts capable of being held by fingers, the two head parts are provided with a screwing hole respectively, one screwing hole is screwed with the French tuyere and the other screwing hole is screwed with the American tuyere, and an annular gas passage is formed between the body wall of the rotary piece and the body part of the shell body; two leakage-stopping rings disposed on the body wall of the rotary piece and located at the both sides of the annular gas passage respectively; a penetration hole disposed on the body wall of the rotary piece and at a position corresponding to the annular gas passage, and used for connecting the annular gas passage with a holding space; a valve seat held in the holding space of the rotary piece, and provided with a valve centre towards the screwing hole end of the American tuyere; and a spring disposed in the holding space of the rotary piece, wherein one end of the spring resists against the inner end wall of the screwing hole end of the French tuyere, and the other end of the spring resists against the inner end wall of the valve seat, so that the valve seat is close to the screwing hole end of the American tuyere in a static state.

Description

technical field [0001] The present invention relates to the tuyere head of an inflatable device, in particular to a dual-purpose tuyere head for an American style mouth and a French style mouth. Background technique [0002] At present, there are two types of common tire nozzles: Schrader Valve and Presta Valve. Schrader Valve is generally used on tires of automobiles, motorcycles and ordinary bicycles, and its outer diameter is 8mm. Commonly found on road racing bikes, the French mouth is slender with an outer diameter of 6mm. The two types of nozzles cannot share one type of nozzle head due to their different outer diameters and structures. In order to solve this problem, there is a dual-purpose nozzle head on the market, which is to install an American nozzle and a French nozzle side by side at one end of the nozzle head, and set a wrench at the other end of the nozzle head to connect the nozzle to be inflated. After the nozzle, pull the wrench to squeeze the rubber sle...
