A check joint structure for a connection of an air nozzle of a tire and a connection hose of an air compressor, the air compressor contains: a box, a sealant supply can, and a connection hose. The box includes a body of the air compressor. The sealant supply can includes an open segment and a supply tube. The connection hose includes a first segment and a second segment. The second segment has a check connector which includes a fitting sleeve, and the fitting sleeve has a threaded orifice, a through orifice, and a projected shoulder. A cylindrical base includes a cylindrical room, a stepped coupling segment, a conduit, and a first stepped portion. A first spring is received into the cylindrical room to abut against the first stepped portion. A valve bolt includes a contacting element, at least one cutout, a head, a conical rib, and a neck.

The present invention relates to a device for mounting tubeless tire comprising an elongated balloon having an opening attached to a bicycle tire valve. The balloon is fabricated from latex or any other suitable elastic material, and is filled with a tire sealant composition. Further, the ballon is designed to burst at a pressure of 15-40 psi.

An embodiment of the present invention provides an air injection valve-integrated spray for spraying and applying polyurethane foam to a desired portion of a tire. The spray includes a polyurethane foam chamber disposed at an end of a coupling portion and keeping polyurethane foam under pressure and an air delivery chamber delivering air injected from an air injection valve to a breaking portion of the polyurethane foam chamber, in which the breaking portion of the polyurethane foam chamber is broken by air coming out of the air delivery chamber, so the polyurethane foam is sprayed.

A pneumatic valve adaptor includes a fast-releasable gas source connector, which includes a top source piece and a rotatable joint, the and at least one valve coupler. The top source piece is connected to a top end of the rotatable joint for receiving and feeding gas supplied from a gas source into the rotatable joint. The rotatable joint has a lower edge in which at least one first engagement section is formed. The valve coupler is provided, at a lateral external surface and a lower end, with at least a second engagement section and a valve connection section. The second engagement section is engageable with or disengage able from the first engagement section through rotation of the rotatable joint. The valve connection section is connectable to a pneumatic valve of an inflatable object for supplying and feeding the gas from the gas source into the inflatable object for inflation.

The present application provides a method for preventing wildfire in a target, the method comprising providing an aqueous composition comprising fire retardant and fibrillar cellulose and applying the aqueous composition to the target. The present application also provides an aqueous composition comprising fire retardant and fibrillar cellulose, and a container comprising the aqueous composition. The present application also provides use of the aqueous composition for preventing wildfire.

Provided is a puncture repair liquid holding container. An outflow channel in a cap mounted to an opening portion of a container body for discharging the puncture repair liquid inside the container interior to a container exterior includes a straight portion including an open end opening toward inside the container body and a closed end terminating inside the cap, and a branching portion including a communicating end communicating with an intermediate area of the straight portion and an open end opening toward the container exterior. A through-hole is at the closed end of the straight portion. A projection on a closing plug and slidably inserted to the straight portion is slidably inserted to the through-hole. States are switchable between open and closed states in which the outflow channel is opened and closed by the closing plug and the projection is positioned in the through-hole or projects from the through-hole.

A self-healing pneumatic tire, which uses the sealant stored in the tire to fix a leak, is disclosed.

A tire valve assembly is disclosed. The tire valve assembly includes a gas nozzle structure, a movable rod, an air pipe, an elastic close contact pad, a screw nut, an elastic O-ring and a dust cap. The tire valve assembly can use a punched hole on the end of the movable rod to receive the tire repair liquid flowing into the air pipe. Take out the movable rod during maintenance to remove the tire repair liquid in the punched hole. When the movable rod is reinstalled in the air pipe, the tire repair liquid remaining on the inner wall of the air pipe will also be squeezed out of the air pipe. With this, the tire repair liquid will no longer block the tire valve assembly.

An inflation system for tubeless bicycle tires may include a valve, a sealant canister, a pump head, and/or a valve core adapter. The valve, sealant canister, and pump head may collectively facilitate sealant injection into a tire by a user. The valve has an external valve seat, and includes a valve body, a valve stem extending through the length of the valve body, and a retaining mechanism for the valve stem disposed interior to the valve body. The valve stem is configured to move relative to the valve body, such that a resilient seating surface disposed at a proximal end of the valve stem is displaced relative to a valve seat formed by an exterior surface of a proximal end of the valve body.

A pressurizable adapter of bicycle valve can be used for a tubeless bicycle tire and contains: a receiving tube, a valve core and a valve cap. The receiving tube includes an internal screw portion, an air outlet, a first connecting part, an air inlet, at least one sealing ring and a connecting section. The valve core used is a standardized valve core. The valve core is housed in the connecting section of the receiving tube, the second connecting section of the valve core is connected to the first end of the receiving tube, and the second connecting portion of the valve core is in contact with the first connecting portion of the receiving tube, so that a closing effect is achieved. The valve cap contains a third connecting portion configured to connect to the first connecting portion and covers the air inlet of the receiving tube.
