Referring to Figures 1 through 5, the suction device of the present invention includes a gas mixing tube 10, two first air intake units 20, and a connecting unit 40. The gas mixture mixing tube 10 has a suction port 11 at one end thereof, and is disposed at an axial interval between the inner and outer layers and the lower two groups of oblique air holes 12 on the pipe wall of the gas mixing tube 10. The inclined holes 12 of each group have a plurality of and are arranged in a ring shape on the same section of the gas mixing tube 10. Each of the oblique air holes 12 is inclined from the outside to the inside in the opposite direction of the suction port 11, and the angle between the central axis of the inclined air hole 12 and the central axis of the gas mixing tube 10 is an acute angle, and the angle range is 40. Between 80 degrees, 70 degrees is the best. In the present creation, the suction opening 11 can be a flat head or a slanted head structure.

The two first air intake units 20 are annular and are sleeved on the gas mixing tube 10 in opposite directions. The inner wall surface of the first air intake unit 20 has an annular groove 21 which is closed by the outer wall of the gas mixing tube 10 to form a closed chamber, and the two first The annular groove 21 of the gas unit 20 is in communication with the upper and lower sets of inclined air holes 12, respectively. The outer wall surface of the first air intake unit 20 has an air inlet hole 22 through which the air inlet hole 22 extends. The slot 21 is connected to a compressed air intake pipe 50 for introducing compressed air, and the intake holes 22 of the two first intake units 20 are connected in parallel through the two compressed air intake pipes 50.

The connecting unit 40 is annular and sleeved on the gas mixing tube 10 and located between the two first air intake units 20. The outer diameter of the connecting unit 40 is the same as that of the two first air intake units 20, and the upper and lower end surfaces of the connecting unit 40 are respectively connected to the two first air intake units 20, so that the three components form a complete and relatively Beautiful structure.

In the first drawing, it is also pointed out that the outer wall of the gas mixing tube 10 has a fixing block 13 which is available for fixing the two compressed air intake pipes 50.

Please refer to FIG. 6 and FIG. 7 , which is another embodiment of the present invention. The structure of the present invention is substantially the same as that of the above embodiment. The difference is that the gas mixing tube 10 of the embodiment has two first sets. The gas unit 20, a second air intake unit 30 and two connection units 40. The second air intake unit 30 is located between the two first air intake units 20, and the two connection units 40 are respectively sandwiched between the second air intake unit 30 and the two first air intake units 20 between. Moreover, the second air intake unit 30 is also annular, and has the same outer diameter as the first air intake unit 20, and has an annular groove 31 on the inner wall surface of the second air intake unit 30 on the outer wall surface.
