Abstract:
1. An air compression device comprising: a case having an air compressor therein; a tire repairing container containing a liquid adhesive for sealing an automobile tire, with the tire repairing container including an adhesive outlet coupler and an air inlet coupler connected with the air compressor; a flexible linking tube including a first end combined with a connector and a second end provided with a protection adapter, with the connector coupled to the adhesive outlet coupler of the tire repairing container, with the protection adapter adapted to be connected with an air nipple of the automobile tire and comprising: an outer cover having an axial hole extending through the outer cover, with the axial hole including a first end having an opening and a second end having a coupling portion for connecting with the air nipple of the tire, with a shoulder formed on an inner end surface of the coupling portion; a base including a connecting section and a cylindrical section with a cylindrical chamber therein, with the cylindrical section of the base received in the axial hole of the outer cover from the opening, with the connecting section protruded outside of the opening of the outer cover, with a passage formed in the connecting section and in communication with the cylindrical chamber; a buffer ring mounted in the cylindrical section of the base and having a through-hole extending through the buffer ring, with a flange formed on an end of the buffer ring and pressed against the shoulder of the outer cover; a valve cock received in the cylindrical chamber of the base and including a pole body extending through the through-hole of the buffer ring, with the valve cock further including a head extending outwardly from an end of the pole body; and a spring sleeved around an outer circumference of the head of the valve cock and received in the cylindrical chamber of the base, with the spring biasing the valve cock towards the buffer ring to close the through-hole of the buffer ring, wherein when the air nipple of the tire is engaged with the coupling portion of the outer cover, the air nipple is in contact with the valve cock and moves the valve cock away from the buffer ring, so that the spring is compressed to open the through-hole of the buffer ring, with a plurality of spaced protruded ribs arranged on a circumference wall of the cylindrical chamber, with an inclined tapering wall formed on a bottom of the cylindrical chamber and including a plurality of platforms, with each of the protruded ribs extended inwardly to one of the plurality of platforms of the inclined tapering wall, with a depressed flowing trough formed between two adjacent platforms of the plurality of platforms, with an arcuate supporting surface formed on an inner side of each platform, and with the head of the valve cock pressed against the supporting surface of the base when the air nipple moves the valve cock away from the buffer ring.
