Abstract
An exhaust device for a grease gun includes: a grease output valve, a normally closed unit, an exhaust valve and an adjusting member. The integral design of the exhaust valve and the adjusting member provided on the grease output valve enables the adjusting member to be adjusted to the exhaust position during the exhaust operation, so that the blocking portion of the adjusting member does not block the exhaust hole from the exhaust passage but allows the exhaust hole to communicate with the exhaust passage. At this time, the air in the grease output passage of the grease output valve can be exhausted through the exhaust passage and the exhaust hole, so that the grease gun can smoothly pump out grease.
