Description
Technical Field
The present invention relates to an exhaust device, and more particularly to an exhaust device for a grease gun.
Background
When the grease gun is used, a used grease barrel is refilled with new grease for repeated use, however, air is often mixed in the grease during filling, and due to the difference of properties of fluids, the grease is gradually pushed out when the rod is pushed, and the air stays in the runner instead, so that when the rod is displaced backwards, the pressure in the runner is reduced, the pressure difference between the grease barrel and the runner is too small, the grease cannot smoothly enter the runner from the grease barrel, and further the grease cannot be pushed out.
Although the conventional grease gun is provided with the exhaust device, the exhaust device is arranged on the side edge of the top cover of the grease gun, and the exhaust device and the rod of the grease gun are not arranged on the same plane, so that the exhaust effect is not achieved unless air is just accumulated at the position corresponding to the exhaust device, and the overall exhaust efficiency of the grease gun is poor.
SUMMERY OF THE UTILITY MODEL
The utility model provides an exhaust device of a grease gun, which mainly aims to improve the exhaust efficiency of the grease gun.
To achieve the above object, the present invention provides an exhaust device for a grease gun, comprising:
the body is provided with a first end and a second end which are opposite to each other, a flow passage penetrates between the first end and the second end, the second end is used for allowing an rod to extend into the flow passage, the body is provided with a hole passage, the hole passage is communicated with the flow passage, a flow passage is arranged at the through position of the hole passage and the flow passage, the hole passage is used for discharging butter, and the flow passage is used for being communicated with the butter barrel;
the normally-closed valve is arranged in the pore passage and is provided with a steel ball and a first spring, the diameter of the steel ball is larger than that of the flow port, and the first spring normally abuts against the steel ball so that the steel ball normally seals the flow port;
the exhaust valve is arranged at the first end of the body, faces the rod, is positioned on the same straight line with the rod, and is provided with a pressing piece, and when the pressing piece is pressed, the flow channel is communicated with the outside.
Therefore, the exhaust device of the grease gun of the present invention is mainly configured such that the exhaust valve faces the rod and is disposed on the same straight line with the rod, so as to achieve better exhaust effect during exhausting.
