When the elastic duct 21, the shaft is added, the f=4 and the guide plate 233 are assembled (as shown in the third figure), then = 罘The structure shown in FIG. 2 is fitted into the curved clamping portion 22, and the notches 242 of the plate member 24 and the notches 2332 of the guiding plate 233 are sequentially engaged by the protrusions 222 of the curved clamping portion 22 to The action of combining the curved clamping portion 22, the plate member μ and the guiding plate 233 is completed, and then the combined curved clamping portion u is placed in the main casing 232 together with the plate member 24 and the guiding plate 233. Inside. In the present embodiment, the main casing 232 is substantially a rectangular casing, and 12 200824917 two adjacent sides are open. In addition, the main casing 232 has a receiving groove 2321 and a corresponding guide. In the embodiment, the shape of the receiving groove 2321 is matched with the shape of the curved clamping portion, that is, the shape of the U-shaped structure is substantially the same, and the guiding groove 2322 is disposed on the groove. The opposite sides of one of the open sides of the main casing 232, and the visibility between the guide grooves 2322 and the distance between the two flanges 221 of the curved guide portion 22 and the plate member 24 and the guide plate 233 The width is matched, and the thickness of the guiding groove 2322 is substantially equal to the total thickness of the flange 221, the plate member 24 and the guiding plate 233, so that the curved clamping portion 22 can open one of the independent sides of the autonomous housing 232. The accommodating groove 2321 is inserted into the accommodating groove 2321, and the flange 221 of the curved clamping portion 22 and the plate member 24 and the guiding plate 233 can be fitted into the guiding groove 2322 to make the arc clamping. The portion 22, the plate member 24 and the guiding plate 233 are fixed inside the main casing 232, and the guiding plate 233 can just seal one of the main casings 232. Put side. Referring to the fourth figure, the other open side of the main casing 232 is closed by a cover 231 having a groove 2311 extending from one side of the cover 231 to the side of the cover 231 wide and narrow. The center of the cover 231, so that the axis 203 of the rotating shaft 20 can enter the groove 2311 from the side of the cover 231 and be erected in the center of the cover 231, so that when the cover 231 is engaged with the main casing 232, The assembly of the suction assembly 2 can be accomplished by positioning the housing 20 with the cover 231 and closing the main housing 232 with the cover 231. Referring to the fourth figure and referring to the first figure, the assembled suction assembly 2 is disposed on the bracket 3, and the shaft center 203 of the rotating shaft 20 is connected with the driving element 4 to constitute the duct suction mechanism 1, and The suction fluid action is performed by a 13 200824917 suction hole 2331 on the guide plate 233 connected to the ink supply conduit (not shown). In the present embodiment, the driving element 4 of the catheter suction mechanism is a plurality of gears, which can drive the shaft 203 by a motor (not shown) transmission gear, and further rotate the shaft 203 to drive the turntable 2〇2 and The roller 2〇1 rotates, so that the roller 201 can circulate and compress the elastic conduit 21, so that the volume change of the internal space of the elastic guide 21 generates a negative pressure to achieve the purpose of sucking the fluid or air in the elastic conduit 21. Of course, the present invention is not limited to the above embodiment, please refer to the fifth figure, which is a schematic diagram of the rotating shaft of the suction assembly of the second preferred embodiment of the present invention. As shown in the figure, each of the rollers 5〇1 of the rotating shaft 50 is respectively connected to the turntable 5〇2, and the axis 503 passes through the turntable 502. However, the first embodiment of the present embodiment and the second figure are better. The embodiment is different in that the roller 5〇1 of the embodiment is further provided with a plurality of card grooves 5011, and each of the card grooves 5〇n can be used for accommodating the corresponding elastic conduit 21 to fix the elastic conduit 21 with respect to The position of the rotating shaft 5〇 can prevent the elastic conduits 21 from interfering with each other when rotating, and the assembly of the elastic conduit 21, the curved clamping portion 22, the plate member 24, the guiding portion 233, the main casing 232 and the casing 231 The manners and their mutual relationship are the same as the first preferred embodiment of the present invention, and thus will not be further described herein. It should be understood that the present invention can be driven by the driving element 4 and control the positive and negative rotation of the rotating shaft 20 to control the suction port 2331 on the guiding plate 233 to become the inlet or outlet of the fluid, for example, when the connection is turned When the driving element 4 of the shaft 203 of the shaft 2 is rotated forward (as indicated by the arrow in the first figure), the suction port 2331 of the upper row is the outlet of the discharge fluid, and the suction port 2331 of the lower row is the suction body. In contrast, when the driving element 4 is reversed, the upper and lower rows of suction 14 200824917 suction port 2331 become the fluid inlet and outlet respectively. Therefore, in this case, only the axial direction of the driving component 4 needs to be controlled, and the fluid pumping can be changed. In the suction direction, the two suction ports 2331 corresponding to the upper and lower sides of the same flexible conduit 21 are connected to change the inlet or outlet of the fluid according to the demand. In addition, the number of flexible conduits 21 in this case is not limited to apply to different types of needs. Of course, the shape of the curved clamping portion 22 of the present invention is not particularly limited, as long as the elastic conduit 21 can be tightly covered, so that the elastic conduit 21 can be closely contacted with the rotating shaft 20 when the rotating shaft 20 rotates. The curved clamping portion 22 of the present case. In summary, the catheter suction mechanism and the suction assembly of the present invention use a curved clamping portion to hold the elastic conduit, and on the other hand, the elastic conduit is in close contact with the rotating shaft to reliably compress the elastic conduit to form a negative pressure to generate suction. The function, on the other hand, prevents the elastic conduits from interfering with each other, resulting in a lack of fluid guidance. In addition, the present invention also utilizes a plurality of rollers to press the elastic conduit to improve the airtightness of the elastic conduit when pumping the fluid, and at the same time, by adjusting the axial direction of the rotating shaft φ, the suction direction of the fluid is changed, so that the conduit suction mechanism is The application is more complete. Furthermore, in the present case, the arc-shaped clamping portion is sleeved with the elastic conduit and the rotating shaft, and the arc-shaped clamping portion, the plate member and the guiding portion are sleeved by the main casing, and the guiding portion and the shell are transmitted through the guiding portion and the shell. The cover closes the main casing, and the position of the rotating shaft is positioned by the cover, which not only strengthens the structure of the suction assembly, but also simplifies the component quantity and assembly process of the suction mechanism of the catheter and the suction assembly, thereby reducing the production cost in this case. And save the assembly processing time, and because the volume occupied by the suction component is not large, the number of flexible conduits is also unlimited, which further expands its application range, greatly improving the conventional continuous ink supply system to utilize the traditional pump 15 200824917 to absorb the residual Many of the shortcomings caused by ink. Therefore, this case is extremely valuable in the industry and has indeed met the requirements of the invention patent. The present invention has been described in detail by the above-described embodiments, and may be modified by those skilled in the art, without departing from the scope of the appended claims.
