Abstract: A device used for pressing air and/or tire sealant into a tire. The device has a device filled with tire sealant, a compression part, a vent port, a fluid port, a linkage and a socket which can be connected to the vent port or the fluid port by the linkage part, so as to supply compressed air generated by the compression part either to the device filled with tire sealant, so as to pump the tire sealant out of the fluid port and into the tire, or to the vent port, so as to pump air into the tire.

Abstract: A device used for pressing air and/or tire sealant into a tire, comprising a main part and a socket part, wherein, the main part further comprises a device filled with tire sealant, a compression part, a vent port and a fluid port, as well as a linkage part. The socket part comprises an inlet pipe used for pressing compressed air or tire sealant into the tire, and comprises also a socket component. One end of the socket component connects to the inlet pipe, while the other end connects to the vent port and/or the fluid port, and the socket component triggering the linkage part to enable either a first channel or a second channel. The first channel is for the compressed air generated by the compression part entering the device of tire sealant, so as to pump the tire sealant out to the fluid port; the second channel is for the compressed air generated by the compression part entering the vent port.
