Portable quick air-inflating apparatus

Abstract

The invention provides a portable quick gas charging device, comprising a through hole, a heat whose one end is equipped with sleeve, a piston rod whose one end extends into the sleeve and connects with inner end of the sleeve and which has pressure storage room, a secondary gas compression cylinder which is jacketed on the piston rod and has secondary gas compression cavity, where a gas inlet gap is between the secondary gas compression cylinder and the piston rod, a primary gas compression cylinder which is jacketed on the secondary gas compression cylinder and has a primary gas compression cavity, where a gas inlet gap is between the primary gas compression cylinder and the secondary gas compression cylinder, and a gas charging control mechanism, where one end of gas transmission pipe in the pressure storage room extending out of the head is connected with the gas charging control mechanism, the other end of the piston rod and the other end of the secondary gas compression cylinder are each equipped with a gas inlet piston respectively, where the gas inlet piston cooperates with the inner walls of the secondary and primary gas compression cylinders and has gas inlet to charge gas into the pressure storage room and the secondary gas compression cavity, and is equipped with one-way valve. And the invention has features of lightweight, small bulk, large charging pressure, short charging time, no noises, portable, and strong universality.

Description

Technical field: [0001] The present invention relates to inflators, and more particularly to portable quick inflators suitable for economy cars, motorcycles, mopeds, bicycles, ball games and other industrial products that require inflating. Background technique: [0002] The inflatable devices on the existing hardware market are: the one, hand beat, foot-operated inflatable devices; [0003] 1. Manual and pedal inflatable devices for cars and motorcycles; [0004] (1) The work efficiency is low, requiring one or two hundred workloads; [0005] (2) No inflation pressure display; [0006] (3) laborious; [0007] 2. Hand-operated and pedal-operated inflatable devices are for bicycles and mopeds; [0008] (1) strenuous; [0009] (2) No inflation pressure display; [0010] (3) Inconvenient to carry (inconvenient for long-distance travel); [0011] 3. The air pump is for cars and motorcycles; [0012] (1) External power is required (especially for motorcycles); [0013] (...
