At this time, the base portion 481 closes the vent end 411 of the three-way seat 41 to prevent the aerosol glue from entering the air compressor 30; the glue of the aerosol can 20 enters the slider 42 through the through hole 421. When the air pressure is large enough, the aerosol glue pushes open the plug 46, so that the aerosol glue enters the through hole 422 through the through hole 421, and then is discharged through the connecting end 412 of the three-way seat 41, and finally is injected into the tire through the connecting tube 50.

[0042] The tire repair and inflation device 100 of the utility model drives the slider 42 to slide through the button 43. When applying glue, one end of the slider 42 pushes open the aerosol can 20, and the other end closes the ventilation end 411 of the three-way seat 41; when inflating, one end of the slider 42 is separated from the aerosol can 20, and the other end is connected to the ventilation end 411 of the three-way seat 41. The tire repair and inflation device 100 applies glue through the aerosol can 20, which reduces the weight and is easy to carry, and combines the functions of tire repair and inflation into one.
