Background

The existing battery formation technology, such as the one disclosed in chinese patent 201922073349.9, relates to the technical field of battery production. The liquid receiving device provided by the patent comprises a cup body, wherein an air inlet and an air outlet which are communicated with an inner cavity of the cup body are formed in the cup body; a partial cavity wall of the inner cavity is located at a front end of the air inlet in an air inlet direction along which the air inlet enters the inner cavity, and is opposite to the air inlet. When the evacuation, during gasified electrolyte can inhale the cup through the air inlet, cools off the liquefaction between air inlet and gas outlet to keep in the inner chamber of cup, because of the partial cavity wall of the air inlet direction orientation inner chamber of air inlet, the electrolyte that gets into the inner chamber from the air inlet receives blocking on partial cavity wall, so, electrolyte can not directly take out the vacuum pipe-line system in through the gas outlet in, avoided causing the harm to the vacuum pipeline.

Although above-mentioned structure can avoid electrolyte to pass through the gas outlet more effectively and directly take out in the vacuum piping system, but in order to make the electrolyte of gasification fully cool off the liquefaction between air inlet and gas outlet, it connects the cup in the liquid device to need reach certain height, moreover because can not be relative between air inlet and the gas outlet, makes like this and connects the whole volume of liquid device big on the large side to make the volume of whole formation partial volume device too big, high inadequately to the utilization efficiency in space.
