Abstract
An inflator includes a body having a first passage, a second passage, and a third passage. The first passage is configured to couple with an air tank or a compressed gas cartridge. The first passage unidirectionally intercommunicates with the second passage and the third passage. The second passage is configured to couple with an air pump. The third passage is configured to couple with a to-be-inflated-object. A first one-way valve unit is disposed between the first and second passages, such that compressed gas is only flowable from the second passage to the first passage. A second one-way valve unit is disposed between the first passage and the third passage, such that compressed gas is only selectively flowable from the first passage to the third passage.
