Description
本創作係關於一種壓差式充氣裝置，特別是關於一種利用內部壓力差，使高壓氣體迅速排出，以對輪胎進行快速充氣之充氣裝置。 The present invention relates to a differential pressure inflator, and more particularly to an inflator that utilizes an internal pressure differential to rapidly expel high pressure gas for rapid inflation of the tire.
按，中華民國專利證書號M537535「壓差式充氣裝置」，其主要係可對輪胎進行快速加壓，但在實際使用上仍有缺失存在，此缺失即是在充氣時按壓開關閥，使釋壓管中的高壓氣體排出外部，該活塞件受到儲氣筒內高壓氣體的推移，令儲氣筒內的高壓氣體經由排氣孔與噴氣管噴出以對輪胎充氣，此時高壓氣體也同時由活塞件與閥本體之間的間隙進入釋壓管，以使活塞件復位再次封擋於排氣孔，但實際上儲氣筒內的高壓氣體僅經由活塞件與閥本體之間的間隙進入釋壓管，無法快速達到儲氣筒與釋壓管內的壓力平衡，該活塞件受到儲氣筒內高壓氣體的作用而不斷地小量位移，無法確實封閉排氣孔，導致儲氣筒內的高壓氣體由噴氣管洩出，因此，習用釋壓閥之設計並非良善，仍存在改善的空間。 According to the Republic of China Patent No. M537535 "Pressure Differential Inflator", which is mainly used to quickly pressurize the tire, but there is still a defect in actual use. The lack of this is to press the on-off valve during inflation to release The high-pressure gas in the pressure tube is discharged to the outside, and the piston member is subjected to the high-pressure gas in the gas cylinder, so that the high-pressure gas in the gas cylinder is ejected through the vent hole and the lance tube to inflate the tire, and the high-pressure gas is also simultaneously composed of the piston member. The gap between the valve body and the valve body enters the pressure release pipe, so that the piston member is reset and sealed again in the exhaust hole, but in fact, the high pressure gas in the air reservoir enters the pressure release pipe only through the gap between the piston member and the valve body. It is impossible to quickly reach the pressure balance in the gas storage cylinder and the pressure release pipe. The piston member is continuously displaced by the action of the high pressure gas in the gas storage cylinder, and the vent hole cannot be surely closed, so that the high pressure gas in the gas storage cylinder is vented by the gas injection pipe. Therefore, the design of the conventional pressure relief valve is not good, there is still room for improvement.
本創作之主要目的在於提供一種具有快速回壓效果之壓差式充氣裝置。 The main purpose of this creation is to provide a differential pressure inflator with a rapid back pressure effect.

The utility model comprises a gas storage cylinder 1 capable of storing high-pressure gas from the outside, a set of the gas injection pipe 2 disposed at the front end portion of the gas storage cylinder 1 for discharging high-pressure gas outward, and a set of pressure relief valves 3 disposed inside the gas storage cylinder 1 An on-off valve 4 disposed on the air reservoir 1 for releasing high-pressure gas, and a pressure release pipe 5 connected between the pressure release valve 3 and the on-off valve 4, the pressure relief valve 3 having a discharge tube 2 The valve body 31 is connected, a piston member 32 is disposed inside the valve body 31, and an elastic member 33 is disposed between the valve body 31 and the piston member 32. The valve body 31 is provided with a plurality of exhaust holes 311. The piston member 32 is formed in a meandering manner and is linearly slidable relative to the valve body 31. A receiving groove 321 is formed therein, and a back pressure hole 322 communicating with the receiving groove 321 is formed. The receiving groove 321 is formed. The elastic member 33 can be accommodated to be attached to the valve body 31 and the piston member. Between 32, the piston member 32 is blocked by the elastic member 33 to block the venting holes 311, and the pressure-recovering hole 322 is used for the high-pressure gas in the air reservoir 1 to enter the accommodating groove 321; The tube 5 is connected between the valve body 31 and the switching valve 4, and when the high pressure gas enters the accommodating groove 321 from the pressure return hole 322, the pressure releasing valve 3 and the switching valve 4 are guided by the pressure releasing tube 5. Filled with high pressure gas.
進行輪胎充氣作業時，如第5圖所示按壓該開關閥4，釋壓管 5內的高壓氣體經由開關閥4排出外部，此時活塞件32的容置槽321與釋壓管5內部的氣壓遠小於儲氣筒1，該活塞件32受到儲氣筒1內高壓氣體推移壓縮彈性件33，而不再封閉該等排氣孔311，以導通儲氣筒1與噴氣管2，儲氣筒1內的高壓氣體立即由噴氣管2向外噴出，進行輪胎充氣作業，高壓氣體同時也經由閥本體31與活塞件32之間的間隙及回壓孔322進入容置槽321與釋壓管5，該活塞件32受到彈性件33回復力的頂掣，並且輔以高壓氣體進入釋壓管5中，以令活塞件32快速復位再次封擋該等排氣孔311。 When performing tire inflation, press the on-off valve 4 as shown in Figure 5, and release the pressure tube. The high-pressure gas in the fifth portion is discharged to the outside through the on-off valve 4. At this time, the air pressure inside the accommodating groove 321 of the piston member 32 and the pressure release tube 5 is much smaller than that of the air reservoir 1, and the piston member 32 is compressed by the high-pressure gas in the air reservoir 1 And the vent hole 311 is no longer closed to open the air reservoir 1 and the lance tube 2, and the high-pressure gas in the air reservoir 1 is immediately ejected outward from the lance tube 2 to perform the tire inflation operation, and the high-pressure gas is also passed through The gap between the valve body 31 and the piston member 32 and the pressure return hole 322 enter the accommodating groove 321 and the pressure release pipe 5, and the piston member 32 is subjected to the top force of the restoring force of the elastic member 33, and is supplemented by the high pressure gas into the pressure release pipe. In 5, the vent holes 311 are again blocked by the quick reset of the piston member 32.
本新型壓差式充氣裝置在釋壓閥3的活塞件32上開設該回壓孔322，讓高壓氣體可更快速填充於釋壓管5中，令釋壓管5與儲氣筒1之間的壓力達到平衡，致使該活塞件32確實封擋於該等排氣孔311上，以阻擋儲氣筒1內的高壓氣體繼續由噴氣管2噴出，因此，本新型壓差式充氣裝置確實可達到快速回壓穩定活塞件32封擋排氣孔311之效果。 The pressure differential type inflator of the present invention opens the back pressure hole 322 on the piston member 32 of the pressure relief valve 3, so that the high pressure gas can be more quickly filled in the pressure release pipe 5, and between the pressure release pipe 5 and the air reservoir 1 The pressure is balanced, so that the piston member 32 is indeed blocked on the vent holes 311 to block the high pressure gas in the air reservoir 1 from being continuously ejected from the lance tube 2. Therefore, the novel differential pressure inflator can achieve rapid speed. The effect of the back pressure stabilizing piston member 32 blocking the venting opening 311 is obtained.
