Description

TECHNICAL FIELD

[0001] The utility model relates to grease filling device technical field, especially a kind of electric double-rod grease gun. BACKGROUND

[0002] The applicant previously applied for an electric double-rod grease gun (CN218268469U), which includes an oil storage cylinder, a plunger pump and a driving device. The plunger pump body is provided with a first plunger cavity and a second plunger cavity that are in communication with the oil storage cylinder and arranged in parallel from top to bottom. The first plunger cavity and the second plunger cavity are respectively slidably provided with a first plunger rod and a second plunger rod. The driving device includes a driving motor, a speed reduction mechanism, a first transmission gear, a second transmission gear, a first eccentric shaft, a second eccentric shaft, a first sliding block and a second sliding block.

[0003] During operation, the high-speed rotating motion of the driving motor is decelerated by the speed reduction mechanism, which drives the first transmission gear to rotate. The second transmission gear rotates accordingly. The rotating motion of the second transmission gear is transmitted to the first sliding block and the second sliding block through the first eccentric shaft and the second eccentric shaft, which drives the first plunger rod and the second plunger rod to move in opposite directions in the first plunger cavity and the second plunger cavity, respectively. That is, when the first plunger rod moves outward to perform the oil suction action, the second plunger rod moves inward to perform the oil pushing action. Conversely, when the first plunger rod moves inward to perform the oil pushing action, the second plunger rod moves outward to perform the oil suction action, thereby achieving the oil injection work of the electric grease gun.

[0004] Compared with the traditional single-plunger-rod structure grease gun, this electric double-rod grease gun can improve the oil injection efficiency. However, the first plunger cavity and the second plunger cavity of this electric double-rod grease gun are arranged in parallel from top to bottom in the plunger pump body. As a result, the distance between the oil inlet of the two plunger cavities and the oil outlet of the oil storage cylinder is actually different, which leads to the fact that the oil injection efficiency of the first plunger cavity located at the upper end is much lower than that of the second plunger cavity located at the lower end, thereby affecting the final oil injection efficiency of the electric double-rod grease gun to some extent. Therefore, it is necessary to provide an electric double-rod grease gun to solve the above problems. SUMMARY
