DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In order to solve the problem in the prior art that after the liquid in the needle tube is discharged by the hyaluronic acid needle, there may still be residual liquid in the needle tube, and the liquid may drip on the surface of the needle tube or other places due to gravity, which is difficult to clean, this embodiment provides the following technical solutions:

[0021] A water-light needle glue injection device for preventing residual liquid from dripping comprises a needle tube 1, a fixed base 16 is arranged on one end of the needle tube 1, a telescopic rod base 6 is arranged on the fixed base 16, a telescopic rod 8 is arranged in the telescopic rod base 6, and a limiting hole 7 is also included. The limiting hole 7 is opened on the telescopic rod base 6, a first connecting spring 9 is arranged on the inner wall of the telescopic rod 8, and a limiting block 10 is arranged on the first connecting spring 9. A push rod 12 is arranged in the needle tube 1, a rubber ring 11 is arranged at one end of the push rod 12, and a fixed block 13 is arranged on the end of the push rod 12 away from the rubber ring 11. A second connecting spring 14 is arranged on the end of the telescopic rod 8 away from the telescopic rod base 6, and a connecting block 15 is arranged on the end of the second connecting spring 14 away from the telescopic rod 8. The connecting block 15 is arranged at a corresponding position of the fixed block 13, and a connecting tube 2 is arranged on the end of the needle tube 1 away from the fixed base 16, and a mounting tube 3 is sleeved on the connecting tube 2, and a needle 4 is arranged on the mounting tube 3, and the needle 4 is limitedly connected with the mounting tube 3;

[0022] In this embodiment, please refer to Figure 1-Figure 3 When the user pours glue or other liquid into the needle tube 1, the end of the push rod 12 provided with the rubber ring 11 is inserted into the needle tube 1 from the end of the needle tube 1 close to the fixed base 16, and then the mounting tube 3 is sleeved on the connecting tube 2, and the work can be started. Before the needle tube 1 is injected with glue, the telescopic rod 8 is first pulled out to a suitable length. When the length is pulled to a suitable length, the limit block 10 pops out from the limit hole 7 provided on the telescopic rod base 6 to fix the telescopic rod 8. During the injection process of the needle tube 1, the push rod 12 is provided with a rubber ring 11. The fixing block 13 abuts against the connecting block 15, exerting a downward pressure on the second connecting spring 14 to deform the second connecting spring 14. When the glue injection is completed, the push rod 12 loses the downward pressure, and the second connecting spring 14 lifts the fixing block 13 to partially retract the push rod 12. When the push rod 12 is inserted into the needle tube 1, the needle tube 1 is in a semi-vacuum state. When the push rod 12 retracts, air flows into the needle tube 1 from the needle head 4, sucking back the glue remaining in the needle tube 1 and the needle head 4 to prevent the glue from dripping from the needle head 4.

[0023] In this embodiment, please refer to Figure 4 A through hole 5 is provided on the needle 4, and the through hole 5 and the needle 4 are integrally arranged. A rotating hinge 17 is provided on the inner wall of the needle 4, and the rotating hinge 17 is welded to the needle 4. An arc-shaped baffle 18 is provided on the movable end of the rotating hinge 17, and the arc-shaped baffle 18 is arranged at a position corresponding to the through hole 5. The arc-shaped baffle 18 can block the through hole 5 when the needle 4 is normally injected with glue to prevent glue from overflowing from the through hole 5. When the push rod 12 retracts, the glue at the lower end of the arc-shaped baffle 18 flows back, and the two arc-shaped baffles 18 are lifted to block the inner wall of the needle 4 to prevent glue from dripping, thereby adding a second layer of protection;

[0024] Working principle: when the user pours glue or other liquid into the needle tube 1, the end of the push rod 12 provided with the rubber ring 11 is inserted into the needle tube 1 from the end of the needle tube 1 close to the fixed base 16, and then the mounting tube 3 is sleeved on the connecting tube 2 to start working. Before the needle tube 1 is injected with glue, the telescopic rod 8 is first pulled out to a suitable length. When it is pulled to a suitable length, the limit block 10 pops out from the limit hole 7 provided on the telescopic rod base 6 to fix the telescopic rod 8. During the injection process of the needle tube 1, the fixed block 13 provided on the push rod 12 abuts against the connecting block 15, exerting a downward force on the second connecting spring 14 to deform the second connecting spring 14. When the injection work is completed, the push rod 12 loses the downward force, and the second connecting spring 14 lifts the fixed block 13 to retract a part of the push rod 12. When inserted into the needle tube 1, the needle tube 1 is in a semi-vacuum state. When the push rod 12 retracts, air flows into the needle tube 1 from the needle head 4, and the glue remaining in the needle tube 1 and the needle head 4 is sucked back to prevent the glue from dripping from the needle head 4. A through hole 5 is provided on the needle head 4, and the through hole 5 and the needle head 4 are integrally arranged. A rotating hinge 17 is provided on the inner wall of the needle head 4, and the rotating hinge 17 is welded and connected to the needle head 4. An arc-shaped baffle 18 is provided on the movable end of the rotating hinge 17, and the arc-shaped baffle 18 is arranged at a position corresponding to the through hole 5. The setting of the arc-shaped baffle 18 can block the through hole 5 when the needle head 4 is normally injected with glue to prevent the glue from overflowing from the through hole 5. When the push rod 12 retracts, the glue at the lower end of the arc-shaped baffle 18 flows back, and the two arc-shaped baffles 18 are lifted, and the inner wall of the needle head 4 is blocked to prevent the glue from dripping, thereby adding a second layer of protection.
