Description

A kind of self-filler of vehicle tyre

The invention discloses a kind of self-filler of vehicle tyre, particularly a kind of self-filler that is directly installed on the vehicle tyre.

The self-filler that is installed on the vehicle tyre of the present invention is not found in the prior art as yet.Existing vehicle tyre and gas filled device (Floor Pump or air compressor), obsolete the time, being mutual incoherent two objects, only just vehicle tyre and gas filled device being linked up when vehicle tyre loses gas, is the inflating tyres of vehicles that loses gas with gas filled device.Must stop when losing the gas inflating tyres of vehicles like this, and connect gas filled device, inflation all needs to delay the regular hour, moreover, usually when vehicle tyre loses gas, because of seeking less than gas filled device, and vehicle can't be moved.Though some vehicle also has gas filled device with car, because gas filled device need occupy certain space, and all needs the inflation of stopping, so still inconvenience to some extent.

The purpose of this invention is to provide a kind of self-filler that is directly installed on the vehicle tyre, it can need not stop when vehicle tyre loses gas, and automatically is the gas inflating tyres of vehicles thanks to that rotates.

The object of the present invention is achieved like this: the present invention be one by the valve body, valve nozzle, pressure air nut, the circle locknut, the tire valve that valve packing ring and hexagonal nut constitute and one are by the inflator body, piston, the micro pump that breather check valve and inflation check valve constitute is formed jointly, it is characterized in that: the afterbody of valve and the admission port of micro pump join, the valve body of its valve and the inflator body of micro pump are the same one of joining, micro pump is installed in the inside of vehicle tyre, and valve stretches out the outside of tire, and is fastened on the crust of tire by the gentle doormat circle of hexagonal nut; In the inflator body of micro pump, be equipped with and promote the spring that piston moves outside fast; During use, be installed in gas filled device on the vehicle tyre with wheel, after gas filled device leaves ground, the piston pressurized of micro pump reduces, and the spring in the inflator body promotes outer fast the moving of piston in the inflator body, and the space in the micro pump is strengthened, air pressure reduces, make the little core-skin in the breather check valve of micro pump leave induction opening, breather check valve is opened, and extraneous air is inhaled in the micro pump by induction opening; When contacting below gas filled device forwards to wheel and with ground, the piston of micro pump is pushed by gravity, stretch in the inflator body, space in the micro pump is reduced, and air pressure raises, and the little core-skin of breather check valve is blocked induction opening, breather check valve is closed, the big core-skin of inflating check valve is simultaneously backed down by high pressure gas, and high pressure gas enters in the tire by air-filled pore, and is reached for the purpose of inflation of tire.

Because micro pump and valve are one, and be installed in the inside of vehicle tyre, the available space of vehicle does not account for, can automatically inflate at any time because of it again for the air filled tyre that loses that rotates, so, we waste time with regard to can not be again stopping when giving inflation of tire, can be not that inflation of tire has influenced vehicle operating because of seeking less than gas filled device more just.
