An anti-spray joint structure of a connection hose of a vehicle air compressor, the vehicle air compressor contains: a box, a sealant supply can, and a connection hose. The box includes a body accommodated in the box and started by a power supply to produce compressed airs. The sealant supply can includes an open segment for accommodating chemical sealant, and the sealant supply can includes a supply tube arranged on the open segment. The connection hose includes a front connector and a rear connector. The rear connector is an anti-spray joint structure and includes a first segment and a second segment removed from and connected with the first segment, and the first segment is connected with the second segment which has a channel of different sizes and shapes so as to be applicable for different tires and to avoid eruption of the chemical sealant.

A device and method for dispensing air and/or sealant to a tire of a vehicle. Power supply for the air compressor is obtained via powered USB instead of the typical 12 V cigarette lighter connector. The position of the tire which is being inflated can also be determined via the data interface of the USB port. By communication between compressor and the vehicle systems interface, the compressor can automatically switch off when the recommended tire pressure has been reached.

An auger for a grinder material for a tire filling machine, having: a cylindrical column; and a plurality of flights extending outwardly from the cylindrical core, wherein (i) the flights are arranged in pairs extending radially outwards from the cylindrical column at 180 degrees to one another, and (ii) each flight has a sharpened leading edge. Each pair of flights are positioned at angles of approximately 50 or 60 degrees to one another, and each flight extends approximately half way around the circumference of the cylindrical column, and there are no outer edge notches in the flights.

A tire repair tool includes a reamer and/or a plugger having a hex end for connection with a power tool.

A combination structure for a hose connected between a tire and an air compressor is disclosed. The air compressor includes a box in which a compressor unit and a sealant bottle are installed. The sealant bottle has an inlet and an outlet. The inlet of the sealant bottle is connected to one outlet tube of the compressor unit. The hose has a first end and a second end. The first end of the hose is adapted to be connected to the outlet tube of the sealant bottle. The second end of the hose can be connected to the combination structure, which generally includes a cap, a core element, and a plug. With the combination structure, the chemical sealant contained in the sealant bottle can be prevented from flowing out to contaminate objects due to incorrect operation or negligence.

Disclosed is a tire building apparatus and a method for joining or cutting tire components. The tire building apparatus includes a rocking member that is movable in a rocking plane in a rocking motion along a rocking line, a translation guide extending parallel to the rocking line and a carriage that is displaceable along the translation guide, wherein the rocking member has a convex edge that defines a minor arc of a circle and extends up to a rotation center, wherein the rocking member is supported by the carriage at the rotation center and is angularly displaceable with respect to the carriage about a rotation axis extending through the rotation center.

An air compressor contains: a box in which the air compressor and a sealant supply device are accommodated. The air compressor is configured to produce high-pressure airs, and the sealant supply device has an air inlet pipe and a supply pipe. An air outlet pipe of the air compressor is connected with the air inlet pipe, and the air compressor is detachable from the sealant supply device. The air inlet pipe is configured to receive the high-pressure airs from the air compressor, the supply pipe is configured to output chemical sealant from the sealant supply device, and a tube is configured to communicate the air inlet pipe with the supply pipe. A rotation element includes a driven portion and a central stem. The rotation element is fitted on the second sub-tube. The central stem of the rotation element abuts against a top of the tube.
