An adapter of a tire cement dispenser has an adapting seat, an air valve mounted in the adapting seat, a flow direction switching device mounted in the adapting seat, a connector mounted on the adapting seat to hold the flow direction switching device in the adapting seat, and a switching button connected to the flow direction switching device. The adapting seat has an air inlet tube for connecting to an air pumping device, and an outlet tube for connecting to a tire. The adapter can be switched to allow the air pumping device to selectively inflate the tire and extrude tire cement for patching the tire. Since the adapter, the air pumping device, and the tire do not have to be connected to or disconnected from each other repeatedly, the tire cement dispenser with the adapter is convenient and time-saving for patching and inflating the tire. |

1. An adapter of a tire cement dispenser comprising:
an adapting seat having
a mounting base having
a mounting recess formed in a bottom of the mounting base and having a lower opening;a switching chamber transversely formed above the mounting recess, being circular in cross-section, and having a front opening;a dividing portion formed between the mounting recess and the switching chamber;an air inlet channel formed through the dividing portion and communicating with the mounting recess and the switching chamber; andan outlet channel formed through the dividing portion, disposed apart from the air inlet channel, and communicating with the mounting recess and the switching chamber;an air inlet tube formed on and protruding from an outer surface of the mounting base, communicating with the switching chamber, and disposed adjacent to the air inlet channel; andan outlet tube formed on and protruding from the outer surface of the mounting base, communicating with the switching chamber, aligning with the air inlet tube, and disposed adjacent to the outlet channel; an air valve mounted to the air inlet channel of the adapting seat; a flow direction switching device pivotally mounted airtightly in the switching chamber of the adapting seat, and having
a central channel radially formed in the flow direction switching device and having a central inlet and a central outlet;a first side channel formed in the flow direction switching device, disposed beside the central channel, and having a first inlet and a first outlet; anda second side channel formed in the flow direction switching device, disposed beside the central channel and opposite to the first side channel, and having
a second inlet, the second inlet of the second side channel and the first outlet of the first side channel oppositely disposed beside the central inlet of the central channel; anda second outlet aligning with the first inlet of the first side channel; a connector securely mounted on a front end of the mounting base of the adapting seat to hold the flow direction switching device in the switching chamber of the mounting base; and a switching button disposed in front of the adapting seat and the connector, and connected to the flow direction switching device; wherein when the central inlet and the central outlet of the central channel of the flow direction switching device respectively communicate with the air inlet tube and the outlet tube of the adapting seat, the first side channel and the second side channel of the flow direction switching device are sealed; and when the first inlet of the first side channel communicates with the air inlet tube of the adapting seat, the first outlet of the first side channel communicates with the air inlet channel of the adapting seat, the second inlet of the second side channel communicates with the outlet channel of the adapting seat, and the second outlet of the second side channel communicates with the outlet tube of the adapting seat, the central channel is sealed. |
