一、背景:全世界最大的自行车生产和使用在中国,据有关资料统计,我国自行车的社会拥有已达三亿辆。长期以来,自行车、摩托车的充气方式一般是采用普通打气筒或电动充气。由于上述充气方式受时间、地点的局限,人们总是不能够及时给车充气,特别是自行车受空气冷热变化影响,气嘴容易漏气或自行车慢撒气,长时间就会损坏自行车内外胎。尤其是摩托车,其活动半径大,经常出现上述情况,即使带上备
I. Background: The world’s largest bicycle production and use is in China. According to statistics, the number of bicycles in China has reached 300 million. For a long time, the inflation method of bicycles and motorcycles generally uses ordinary air pump or electric air charging. Due to the limitation of time and place, the above-mentioned inflation method cannot always inflate the vehicle in time. In particular, the bicycle is affected by changes in the coldness and heat of the air. The gas nozzle is prone to air leakage or the bicycle is slowly vaporized, and the bicycle inner and outer tires are damaged for a long time. Especially motorcycles, which have a large radius of activity, are often present, even if they are brought up.
