前述两种类型的螺接式充气嘴设计，本发明人皆已广泛销售于市场中并颇受好 评， 但随着各种气嘴不断有新的市场需求， 便有业者开发出如图 3所示的另一型态 法式气嘴 50,该类法式气嘴 50的特征为取消原有前述的第一螺接部 61的螺纹，转 而以无螺纹的管体 51取代， 仅保留与前述的第二螺接部 62相同的螺接部 52及与 进气端 53, 因此就现有螺接式充气嘴而言， 仅剩前述的充气嘴 80可供使用， 然该 转接式充气嘴 80仅供转接美式气嘴 72使用， 对于一般专用法式气嘴 50的人而言 并不实用， 尤其法式气嘴 50的进气量大的特性， 又为竟赛型车种所广为使用， 使 用者当然会选用专用的充气嘴， 避免转接时产生不必要的麻烦及故障产生的可能， 而针对喜好使用螺接式充气嘴或为使用该类型法式气嘴 50的消费者而言， 现行产 品显然无法提供供前述状况使用的充气嘴， 因此开发一种可针对使用前述法式气嘴 50又为螺接式充气嘴的结构， 显然有其必要性。 发明内容 The above two types of screw-type aeration nozzle designs have been widely sold in the market and are well received by the present inventors. Commentary, but as various nozzles continue to have new market demands, some companies have developed another type of French nozzle 50 as shown in Fig. 3. The French nozzle 50 is characterized by the elimination of the aforementioned The thread of the first screwing portion 61 is instead replaced by the unthreaded pipe body 51, and only the same screwing portion 52 and the air inlet end 53 as the second screwing portion 62 are retained, so that the existing screwing is performed. In the case of the inflatable nozzle, only the aforementioned inflation nozzle 80 is available, but the adapter inflation nozzle 80 is only used for the transfer American air nozzle 72, and is not practical for the general-purpose French air nozzle 50. In particular, the large intake air amount of the French air nozzle 50 is widely used for the race type vehicle, and the user will of course select a dedicated inflation nozzle to avoid unnecessary trouble and troubles caused by the transfer. For consumers who prefer to use a screw-type aeration nozzle or to use this type of French air nozzle 50, the current product obviously cannot provide the inflation nozzle for the aforementioned conditions, and therefore develops a method that can be used for the use of the aforementioned French air nozzle 50. For the structure of the screw-type inflation nozzle, it is obvious that it must Sex. Summary of the invention
