Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Refer to Figures 1 - 5 , a liquid preparation device for pearl eye drops, including a liquid preparation barrel 1, the upper end of the liquid preparation barrel 1 is fixedly communicated with a liquid inlet pipe 2, the upper end of the liquid inlet pipe 2 is fixedly connected with a liquid inlet cylinder 3, and a control valve 4 is fixedly installed on the liquid inlet pipe 2;

[0024] A circular hole is opened on the side of the liquid inlet cylinder 3, a regulating liquid pipe 5 is horizontally and fixedly installed in the circular hole, one end of the regulating liquid pipe 5 is fixedly installed with a mounting bracket 6, a threaded hole is opened on the mounting bracket 6, an adjusting screw 7 is threadedly inserted into the threaded hole, one end of the adjusting screw 7 is fixedly installed with a push block 8, the push block 8 is slidably inserted into the regulating liquid pipe 5, and a plugging component for blocking itself is arranged in the circular hole. The end of the adjusting screw 7 away from the push block 8 is fixedly installed with an adjusting block 14, an anti-slip pattern is opened on the adjusting block 14, and a sealing pad is fixedly installed on the surface of the push block 8, and the side of the sealing pad is in sliding contact with the inner wall of the regulating liquid pipe 5.

[0025] When the liquid in the liquid inlet cylinder 3 is too much, the circular hole is opened through the plugging component, and the liquid in the liquid inlet cylinder 3 will enter the regulating liquid pipe 5. Then, the adjusting block 14 is rotated to drive the adjusting screw 7 to rotate. Under the action of the threaded hole opened on the mounting bracket 6, the adjusting screw 7 can be driven to move away from the liquid inlet cylinder 3. When the adjusting screw 7 moves, it will drive the push block 8 to move in the regulating liquid pipe 5. Since a sealing pad is fixedly installed on the surface of the push block 8, the liquid in the regulating liquid pipe 5 will not flow out. As the push block 8 moves away from the liquid inlet cylinder 3, more and more liquid enters the regulating liquid pipe 5 until the liquid in the liquid inlet cylinder 3 reaches an appropriate amount. Then, the circular hole is closed through the plugging component, and the control valve 4 is opened. At this time, the liquid in the liquid inlet cylinder 3 will enter the liquid preparation barrel 1 through the liquid inlet pipe 2. When the push block 8 moves in the regulating liquid pipe 5, the amount of the taken liquid can be accurately controlled, without multiple operations, the operation is simple, time-saving and labor-saving.

[0026] A rectangular groove is provided on the inner wall of the circular hole. A moving hole communicating with the rectangular groove is provided on the side surface of the liquid inlet cylinder 3. The sealing and plugging assembly includes a sealing plate 9 slidably installed in the rectangular hole, two symmetrically fixed spring rods 10 installed on the upper end of the sealing plate 9, and an L-shaped moving block 11 fixedly installed on the upper end of the sealing plate 9. One end of the spring rod 10 is fixedly connected to the inner wall of the rectangular groove. The moving block 11 is slidably installed in the moving hole and one end passes through the moving hole. The lower end of the sealing plate 9 is inserted into the circular hole. One end of the moving block 11 is rotatably installed with a support rod 12. A positioning block 13 is fixedly installed on the regulating liquid pipe 5, and a positioning groove is provided on the positioning block 13;

[0027] When it is necessary to open the circular hole, the moving block 11 can be moved upward, so as to drive the sealing plate 9 to move vertically upward. The spring rod 10 is compressed. One end of the sealing plate 9 will slowly move out of the circular hole, thus opening the circular hole. Then rotate the support rod 12 to align one end of the support rod 12 with the positioning groove provided on the positioning block 13. Then release the moving block 11. Under the action of the elastic force of the spring rod 10, one end of the support rod 12 will be inserted into the positioning groove, so as to limit the movement of the moving block 11.

[0028] A strip-shaped hole is provided on the surface of the liquid inlet cylinder 3. A plastic plate made of a transparent material is fixedly installed in the strip-shaped hole, and scales are engraved on the plastic plate. When the prepared liquid in the liquid inlet cylinder 3 enters the regulating liquid pipe 5 through the movement of the push block 8, the operator can directly observe the amount of the prepared liquid in the liquid inlet cylinder 3 by observing the scale on the plastic plate of the liquid inlet cylinder 3.

[0029] In the present utility model, when the prepared liquid in the liquid inlet cylinder 3 is excessive, the circular hole is opened through the sealing and plugging assembly. The prepared liquid in the liquid inlet cylinder 3 will enter the regulating liquid pipe 5. Then rotate the regulating screw rod 7. Under the action of the mounting frame 6, drive the push block 8 to move in the regulating liquid pipe 5. As the push block 8 moves in the direction away from the liquid inlet cylinder 3, more and more prepared liquid enters the regulating liquid pipe 5. Until the prepared liquid in the liquid inlet cylinder 3 reaches an appropriate amount, the circular hole is closed through the sealing and plugging assembly. When the push block 8 moves in the regulating liquid pipe 5, the amount of the taken-out prepared liquid can be accurately controlled, without multiple operations, and the operation is simple, time-saving and labor-saving.

[0030] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
