This creation is related to the technical design of a non-reversal structure with a non-reversal effect after the combination of a tire air nozzle and an air compressor hose.

The air nozzle of automobile tires is a very extensive and common technical structure. Its function is nothing more than the application technology to inflate and deflate the tires. At present, there is also a kind of chemical glue that can be used to repair the damaged tires at any time. The first-aid device for car tires that is also inflated. The device can be combined with an air compressor to fill a rubber tank for tire repair. The tank can be combined with the air outlet valve of the air compressor. The compressed air can be controlled by the valve to make the glue liquid. With the compressed air output from the outer end connector of the hose, if the hose connector is firmly combined with the air core of the car tire, the output tire repair fluid and compressed air can smoothly enter the damaged tire and be inflated to the normal tire pressure. The state is very convenient. The only thing the designer should consider is how to prevent the chemical glue in the refill tank from bursting and overflowing from the outer end of the hose. This kind of bursting and overflowing joint design is bound to affect the user. Or other items, in view of the fact that the general valve concept is already a kind of public technical knowledge in academic theory, the creator based on academic theory and accumulated years of technical design experience, created a car tire valve that can be compared with hoses. Combining and preventing the chemical glue in the glue tank from bursting out during use, it is a practical article that can make consumers and users feel relieved to use.

Please refer to Figures 1 and 8. When the user screwed the screw hole 61 of the non-return joint 5 with the air nozzle 9 of the automobile tire 99, the valve plug 8 of the non-return joint 5 will first touch and move the tire The air core center needle 94 in the air nozzle 9 makes the valve blocking ring 96 of the air core center needle 94 move away from the valve seat 932 of the hollow sleeve 93 (refer to the ninth figure at the same time) that was originally blocked and contacted. The screw hole 61 of the non-return joint 5 is completely screwed to the air nozzle 9 of the automobile tire 99. Since the valve plug 8 is touched by the air core center needle 94 of the air nozzle 9, the valve plug 8 moves to the right to compress the spring 51 causes the blocking ring 86 to leave the oblique tapered wall 74 of the base 7 which was originally blocked to contact, and the hollow chamber 70 of the base 7 forms a flowable path state. At this time, the chemical glue pushed by the air can pass through the base The passage 73 of 7 and the flow side passage 83 of the expanded end 82 outside the valve plug 8 enter the hollow chamber 70, and then pass through the flow groove 85 of the valve plug 8 in the hollow chamber 70 and the flow port 790 of the top contact pad 79 , The inner chamber 60 and the screw hole 61 of the cover 6, and finally enter the damaged tire 99 through the circulation hole 922 of the front seat 92 in the air nozzle 9, the hollow sleeve 93 and the valve seat 932 of the hollow sleeve 93 In this way, the action of filling the rubber into the tire 99 to repair the tire can be achieved. Of course, the compressed air can continue to enter the flat tire 99 for inflation until the normal tire pressure.

In summary, this creation provides a non-reversal structure combining the tire 99 air nozzle 9 and the air compressor hose connector, which prevents the user from improperly operating the chemical glue caused by bursting out The lack of it is also very progressive, which obviously meets the requirements of a creative patent.
