Description

可手動或連接氣瓶打氣的充氣裝置 Inflator that can be manually or connected to a gas cylinder

本發明涉及一種對諸如輪胎、氣墊、...等需要充氣之物體打氣之充氣裝置,特別是可以方便轉換為手動打氣或氣瓶快速充氣之充氣裝置。 The present invention relates to an inflator for inflating an object such as a tire, an air cushion, or the like, and particularly an inflator that can be easily converted into a manual air pump or a gas cylinder.

一般的打氣筒大體上包含有唧筒、設於唧筒的頭部,以及設於該頭部的充氣嘴,充氣嘴接設於被充氣物的氣嘴後,藉由操作唧筒產生壓縮氣體,進而使氣體經由頭部、充氣嘴與氣嘴充入被充氣物內。 A general pump generally includes a cartridge, a head disposed on the cartridge, and an inflation nozzle disposed on the head. The inflation nozzle is connected to the nozzle of the inflated body to generate compressed gas by operating the cartridge, thereby The gas is charged into the inflated body through the head, the inflator, and the air nozzle.

基於方便攜帶的考量,迷你型的輕便型打氣筒頗受長途自行車騎士的喜愛;如第一圖所示的習知輕便型打氣筒A,係包括有一筒體A1、一可相對於筒體A1移動的頭部A2、以及一設於頭部A2的充氣嘴A3;打氣時,將充氣嘴A3螺合於被充氣物的氣嘴,然後操作筒體A1相對於頭部A2軸向運動,便能以手動操作方式將氣體經由頭部A2及充氣嘴A3充入被充氣物內。該第一圖所示之輕便型打氣筒的詳細結構與使用方式可參考TW M315778號專利。 Based on the convenience of carrying, the mini-type portable pump is popular among long-distance bicycle riders; as shown in the first figure, the conventional portable pump A includes a cylinder A1 and a relative to the cylinder A1. a moving head A2, and an inflating nozzle A3 disposed on the head A2; when inflating, the inflating nozzle A3 is screwed to the inflating nozzle, and then the cylinder A1 is operated to move axially relative to the head A2. The gas can be charged into the inflated body via the head A2 and the inflator A3 by manual operation. The detailed structure and use of the portable pump shown in the first figure can be referred to the TW M315778 patent.

由於手動打氣較麻煩且費力,而具有快速且省力充氣效果的空氣壓縮機則不方便甚至無法隨身攜帶,故體積小而方便攜帶的高壓氣瓶為頗受歡迎的選擇,尤其是對於長途自行車騎士而言更是實用。如第二圖所示,所述氣瓶C為具有一定強度的金屬瓶體,其內部充填有高壓氣體(一 般為二氧化碳,CO2),其瓶口以金屬膜密封;當要對輪胎或其他被充氣物進行充氣時,必須在氣瓶C的瓶口連接一氣瓶接頭B,使設於氣瓶接頭B內的尖錐狀刺穿元件將所述金屬膜刺破,同時利用該刺穿元件的尖錐形狀塞住該金屬膜被刺破的洞孔,而後將氣瓶接頭B的充氣嘴B1螺接於被充氣物的氣嘴,再操作旋轉該氣瓶C而使刺穿元件適當地脫離被刺穿的洞孔而連通該氣瓶接頭B與氣瓶C,使氣瓶C內的高壓氣體經由氣瓶接頭B及充氣嘴B1充入被充氣物內;前述氣瓶C與氣瓶接頭B之連通或中斷連通,係經由氣瓶接頭B與氣瓶C正向或反向旋轉來控制者,該第二圖之氣瓶接頭B的詳細結構與使用方式可參考TW I405927號專利。 Because manual air pumping is cumbersome and laborious, and air compressors with fast and labor-saving aeration effects are inconvenient or even impossible to carry around, high-pressure gas cylinders that are small and convenient to carry are popular choices, especially for long-distance bicycle riders. It is more practical. As shown in the second figure, the gas cylinder C is a metal bottle body with a certain strength, and the inside thereof is filled with a high-pressure gas (generally carbon dioxide, CO 2 ), and the bottle mouth is sealed with a metal film; when the tire or other tires are to be When inflated by the inflator, a cylinder connector B must be connected to the mouth of the cylinder C to pierce the metal film by the tapered tapered piercing member provided in the cylinder connector B, and the piercing member is utilized at the same time. The tapered shape plugs the hole through which the metal film is punctured, and then the inflation nozzle B1 of the cylinder connector B is screwed to the gas nozzle of the inflated body, and then the cylinder C is operated to rotate the piercing member appropriately. Disengaging the pierced hole and connecting the cylinder connector B and the cylinder C, so that the high-pressure gas in the cylinder C is filled into the inflated body through the cylinder connector B and the inflation nozzle B1; the cylinder C and the cylinder The connection or disconnection of the connector B is controlled by the cylinder connector B and the cylinder C rotating forward or backward. The detailed structure and usage of the cylinder connector B of the second figure can be referred to the TW I405927 patent.
