The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings.
As fig. 1 to 5, the utility model relates to a bubble-free filling device of syringe, including medicine storage tank 1, electric three-way valve 2, drain pipe 3, plunger rod 4, plunger pipe 5 and drive actuating cylinder 6, medicine storage tank 1, drain pipe 3 and plunger pipe 5 are connected respectively to electric three-way valve 2's three valve port, and plunger rod 4 pegs graft in plunger pipe 5, and the free end and the plunger rod 4 fixed connection that drive actuating cylinder 6 are equipped with vacuum tube 11 and advance pencil 12 on medicine storage tank 1. The medicine inlet pipe 12 is positioned above the bubble breaking body 7.
The utility model provides a medicine storage tank 1 is the toper structure, and evacuation pipe 11 sets up on medicine storage tank 1's top surface, advances pencil 12 and sets up on medicine storage tank 1's lateral wall, and medicine storage tank 1's bottom links to each other with electric three-way valve 2's valve port.
The utility model discloses be equipped with vacuum tube 11 at the top of medicine storage tank 1, guaranteed before advancing the medicine, no air in the medicine storage tank has solved the bubble that produces in the liquid storage pot, makes liquid when filling to bottle, can mix with the bubble.
When the liquid is fed, the liquid flows into the medicine storage tank 1 from the medicine feeding pipe 12 and also generates bubbles, and a bubble breaking body 7 is arranged on the inner wall of the medicine storage tank 1 for reducing the bubbles generated in the liquid feeding process. The bubble breaking body 7 is in interference fit with the medicine storage tank 1.
The bubble breaking body 7 is of a circular structure, a through hole is formed in the circle center direction of the bubble breaking body 7, a honeycomb network 71 is fixedly connected in the through hole, and an overflow groove 72 is formed in the circumferential direction of the upper end face of the bubble breaking body 7.
The use principle of the bubble breaking body 7 is as follows: when the liquid flows into the medicine storage tank 1 from the medicine inlet pipe 12, the liquid firstly enters the overflow groove 72 in the bubble breaking body 7, after the overflow groove 72 is filled with the liquid, the liquid overflows towards the honeycomb network 71 and falls into the medicine storage tank 1, and the honeycomb network 71 can break part of bubbles. The overflow groove 72 reduces the speed of the filling liquid entering the medicine storage tank 1 and reduces the generation of bubbles.
