Abstract
This utility model discloses a plunger electric grease lubrication pump, including a pump body, an oil reservoir mounting base on the pump body, and an outer cover detachably mounted on the oil reservoir mounting base. The outer cover houses a compression spring and an oil reservoir pressure plate. The oil reservoir mounting base has an oil reservoir mounting port at its center, matching the oil reservoir. A magnetic ring is mounted on the oil reservoir pressure plate, and a proximity switch corresponding to the magnetic ring is mounted on the oil reservoir mounting base. This utility model lubricates the pump using an oil reservoir; the oil reservoir is simply replaced when it is empty, making operation simple. Furthermore, the interaction between the magnetic ring on the oil reservoir pressure plate and the proximity switch on the oil reservoir mounting base provides a reminder when the oil reservoir is empty.
