The aforementioned communication holes 455a, 455b, 455c and 455d penetrate through the third aperture portion 450, and one of the communication holes 455a, 455b, 455c and 455d communicates with one of the first channel structures 451a, 451b, 451c and 451d and One of the second channel structures 453a, 453b, 453c and 453d.

The inlets 411, 413, 415 and 417 of the above-mentioned 4th diagram, the first passages 421, 423, 425 and 427 of the 4th diagram, the outlets 431, 433, 435 and 437 of the 4th diagram, and the second passage 441 of the 4th diagram 443, 445, and 447, and the first channel structures 451a, 451b, 451c, and 451d of FIG. 4f and the second channel structures 453a, 453b, 453c, and 453d are all equal in number. In one embodiment, the number of the inlet, the first passage, the outlet, the second passage, the first passage structure, and the second passage structure are at least three.

Please continue to refer to Figures 4a through 4f. Due to the aforementioned communication relationship, when the liquid flows in from the inlet 411 of the input portion 410, the liquid flows through the first passage 421 of the first aperture portion 420, the first passage structure 451d of the third aperture portion 450, and the communication hole. The 455d and the second channel structure 453d, and the second channel 441 of the second aperture portion 440, are discharged from the outlet 431 of the output portion 430.

When the connecting shaft 400a rotates, although the first aperture portion 420 rotates, the first channel structures 451a, 451b, 451c, and 451d of the fourth embodiment are arranged concentrically, so the first channel structures 451a, 451b, The first channels 421, 423, 425, and 427 of the first aperture portion 420 are still connectable to the 451c and 451d.

Similarly, when the connecting shaft 400a is rotated, the second passage structures 453a, 453b, 453c, and 53d of FIG. 4f can still communicate with the second passages 441, 443, 445, and 447 of the second aperture portion 440.

According to the above description, the multi-way reversing valve can more easily change the direction of the liquid flow and improve the efficiency of the extraction process. In one embodiment, the effect of continuous extraction can be achieved using only one multi-way reversing valve.

Please refer to FIG. 5, which is a flow chart showing a multi-way reversing valve for continuous extraction according to still another embodiment of the present invention. In one embodiment, the structure of the continuous extraction apparatus 500 is substantially the same as that of the continuous extraction apparatus 300 of FIG. 3, the difference being that the continuous extraction apparatus 500 includes only one multi-way reversing valve 510, of which The structure of the reversing valve 510 is the same as that of the multi-way reversing valve 400 of FIG. Similarly, since the user can adjust the flow direction of the extract by rotating the multi-way switching valve 510 and flow through the path The portions 530a and 530b are capable of continuous extraction. Moreover, the multi-way reversing valve 510 can further improve the efficiency of continuous extraction compared to the multi-way reversing valves 310 and 320 of FIG. 3, and the multi-way reversing valve 510 can reduce the manufacturing cost of the continuous extraction device 500 and Time costs.

It can be seen from the above embodiments of the present invention that the multi-way reversing valve of the present invention has an advantage of adjusting the flow direction of the liquid flowing through the multi-way reversing valve by the channel structure arranged in a concentric circle and the communication relationship between the channels for continuous operation. Extract and increase the efficiency of extraction, as well as the extraction efficiency of the extract, while reducing the cost of continuous extraction.

The present invention has been disclosed in the above embodiments, and is not intended to limit the present invention. Any one of ordinary skill in the art to which the present invention pertains can make various changes without departing from the spirit and scope of the invention. The scope of protection of the present invention is therefore defined by the scope of the appended claims.
