DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In the embodiment of the present application, by providing a filling device with a vacuum recovery function, it effectively solves the problem that after a common filling device fills a container with liquid, there will be a lot of liquid remaining in the pipeline, and it is difficult to recover the liquid in the pipeline. In the long run, this will lead to a large amount of liquid waste and cause liquid loss. When the container is filled, the second valve is closed and the vacuum pump is turned on. The vacuum pump sucks the liquid remaining in the fourth connecting pipe into the transfer tank. When there is less liquid in the fourth connecting pipe, the vacuum pump continues to work. At this time, due to the internal and external air pressure difference, the valve flap will open to both sides, and air will enter the third connecting pipe, pushing the liquid to move in the direction of the second connecting pipe. When there is obviously no liquid in the fourth connecting pipe, the first valve is closed to lock the liquid in the second connecting pipe and wait to be filled into the container next time, thus achieving the function of quickly recovering the liquid. Align the pipeline with the threaded cylinder, put the pipeline on the side wall of the fourth connecting pipe, and rotate the threaded cylinder counterclockwise. The threads inside the threaded cylinder make the pipeline move from right to left and fix the pipeline inside the threaded cylinder. At this time, the pipeline presses against the gasket, causing the spring to be compressed by force, and the pipeline will fit tightly with the spring, increasing the sealing performance between the fourth connecting pipe and the pipeline, thus achieving the function of improving the sealing performance.

[0025] Embodiment

[0026] Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 4As shown in the figure, the technical solution in the embodiment of the present application effectively solves the technical problem that after a common filling device fills a container with liquid, there will be a lot of liquid remaining in the pipeline, and it is difficult to recycle the liquid in the pipeline. Over time, this will lead to a large amount of liquid waste and cause liquid loss. The general idea is as follows: A filling device with a vacuum recovery function, including a transfer tank 11, a recovery mechanism is provided on the side wall of the transfer tank 11. The recovery mechanism includes a first connecting pipe 13, a second connecting pipe 14, a third connecting pipe 15, a valve flap 16, a filter screen 17, a first valve 18, and a fourth connecting pipe 19. The second connecting pipe 14 is fixedly installed on the side wall of the first connecting pipe 13, the first valve 18 is fixedly installed on the side wall of the second connecting pipe 14, the fourth connecting pipe 19 is fixedly installed on the side wall of the second connecting pipe 14, the third connecting pipe 15 is fixedly installed on the side wall of the fourth connecting pipe 19, the valve flap 16 is fixedly installed inside the third connecting pipe 15, and the filter screen 17 is fixedly installed inside the third connecting pipe 15. When the container is filled, the second valve 23 is closed, and the vacuum pump 12 is turned on. The vacuum pump 12 sucks the liquid remaining inside the fourth connecting pipe 19 into the transfer tank 11. When there is less liquid inside the fourth connecting pipe 19, the vacuum pump 12 continues to work. At this time, due to the internal and external air pressure difference, the valve flap 16 will open to both sides, and air will enter the inside of the third connecting pipe 15, pushing the liquid to move in the direction of the second connecting pipe 14. When there is obviously no liquid inside the fourth connecting pipe 19, the first valve 18 is closed, locking the liquid inside the second connecting pipe 14, and waiting to be filled into the container next time, so as to achieve the function of quickly recovering the liquid.

[0027] A vacuum pump 12 is fixedly installed on the top of the transfer tank 11. The vacuum pump 12 is fixedly installed with the first connecting pipe 13. A fifth connecting pipe 21 is fixedly installed at the bottom of the transfer tank 11. A water pump 22 is fixedly installed on the side wall of the fifth connecting pipe 21. A second valve 23 is fixedly installed on the side wall of the water pump 22. A threaded cylinder 24 is rotatably installed on the side wall of the fourth connecting pipe 19. One end of the fourth connecting pipe 19 away from the second connecting pipe 14 is fixedly installed with a spring 25. One end of the spring 25 away from the fourth connecting pipe 19 is fixedly installed with a washer 26. Align the pipeline with the threaded cylinder 24, put the pipeline on the side wall of the fourth connecting pipe 19, and rotate the threaded cylinder 24 counterclockwise. The threads inside the threaded cylinder 24 cause the pipeline to move from right to left, fixing the pipeline inside the threaded cylinder 24. At this time, the pipeline presses against the washer 26, causing the spring 25 to be compressed by force, and the pipeline will fit tightly with the spring 25, increasing the sealing performance between the fourth connecting pipe 19 and the pipeline, so as to achieve the function of improving the sealing performance.

[0028] A water inlet pipe 27 is fixedly installed on the side wall of the transfer tank 11, which is convenient for putting liquid into the device.

[0029] In view of the problems existing in the prior art, the utility model provides a filling device with a vacuum recovery function. After filling the container, the second valve 23 is closed, and the vacuum pump 12 is turned on. The vacuum pump 12 sucks the residual liquid inside the fourth connecting pipe 19 into the transfer tank 11. When there is less liquid inside the fourth connecting pipe 19, the vacuum pump 12 continues to work. At this time, due to the internal and external air pressure difference, the valve flap 16 will open to both sides, and air will enter the third connecting pipe 15, pushing the liquid to move in the direction of the second connecting pipe 14. When there is obviously no liquid inside the fourth connecting pipe 19, the first valve 18 is closed to lock the liquid inside the second connecting pipe 14 and wait to be filled into the container next time, so as to achieve the function of quickly recovering the liquid. Align the pipe with the threaded cylinder 24, sleeve the pipe on the side wall of the fourth connecting pipe 19, and rotate the threaded cylinder 24 counterclockwise. The threads inside the threaded cylinder 24 make the pipe move from right to left and fix the pipe inside the threaded cylinder 24. At this time, the pipe presses against the gasket 26, causing the spring 25 to be compressed. The pipe will closely fit with the spring 25, increasing the sealing performance between the fourth connecting pipe 19 and the pipe, so as to achieve the function of improving the sealing performance.

[0030] Working principle:

[0031] First step, after filling the container, the second valve 23 is closed, and the vacuum pump 12 is turned on. The vacuum pump 12 sucks the residual liquid inside the fourth connecting pipe 19 into the transfer tank 11. When there is less liquid inside the fourth connecting pipe 19, the vacuum pump 12 continues to work. At this time, due to the internal and external air pressure difference, the valve flap 16 will open to both sides, and air will enter the third connecting pipe 15, pushing the liquid to move in the direction of the second connecting pipe 14. When there is obviously no liquid inside the fourth connecting pipe 19, the first valve 18 is closed to lock the liquid inside the second connecting pipe 14 and wait to be filled into the container next time, so as to achieve the function of quickly recovering the liquid.

[0032] Second step, align the pipe with the threaded cylinder 24, sleeve the pipe on the side wall of the fourth connecting pipe 19, and rotate the threaded cylinder 24 counterclockwise. The threads inside the threaded cylinder 24 make the pipe move from right to left and fix the pipe inside the threaded cylinder 24. At this time, the pipe presses against the gasket 26, causing the spring 25 to be compressed. The pipe will closely fit with the spring 25, increasing the sealing performance between the fourth connecting pipe 19 and the pipe, so as to achieve the function of improving the sealing performance.

[0033] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
