[0031] Embodiment 1

[0032] Referring to Figure 1 For solving the problem of the soft shaft knotting in the pipe dredger, this embodiment proposes a multi-directional conduit, which includes an upper end portion 100, a lower end portion 200, and at least two bending portions 300. The upper end portion 100 is located at the top of the multi-directional conduit, and the lower end portion 200 is located at the bottom of the multi-directional conduit. The soft shaft enters from the lower end portion 200, passes through the bending portions 300, and then exits from the upper end portion 100. The provided bending portions 300 are structures for preventing the soft shaft from knotting when entering and exiting. It is not difficult to understand here that the multi-directional conduit can be integrally arranged, or can be separately arranged into a multi-segment structure. The integral type means that the upper end portion 100, the lower end portion 200, and at least two bending portions 300 are integrally injection-molded. The split type is divided into a multi-segment pipe structure. At the same time, the bending portions 300 are arranged between the upper end portion 100 and the lower end portion 200. The projection of the bending portions 300 in the vertical plane extends from top to bottom, and the axial sections of adjacent two bending portions 300 in the bending direction are non-coplanar. Generally speaking, the multi-directional conduit extends downward in the vertical direction, and bends in the horizontal plane. The number of bends is at least 2 times, and the bending directions in the horizontal plane are different. It can also be described as a pipe that is continuously bent in space but the bending directions are non-coplanar, resulting in a certain interval between the projections of the upper end portion 100 and the lower end portion 200 in the horizontal plane, that is, they are offset.

[0033] Embodiment 2

[0034] Referring to Figures 2 - 5 The difference between this embodiment and the above embodiment is that in this embodiment, the multi-directional conduit is specifically separately arranged into a multi-segment structure, including a first pipe body 400, a second pipe body 500, and a third pipe body 600 that are sequentially connected. It is not difficult to understand that in this embodiment, it is divided into three sections of pipes according to two bending portions 300. Those skilled in the art can set the bending portions 300 and the specific number of pipe segments according to actual needs, which will not be elaborated here.

[0035] Further, more specifically, the upper end portion 100 is located at the top of the first tube body 400, the lower end portion 200 is located at the bottom of the third tube body 600, the upper and lower ends of the second tube body 500 are respectively connected to the first tube body 400 and the third tube body 600, and at the same time, the second tube body 500 has a first bending portion 301 and the third tube body 600 has a second bending portion 302.

[0036] Further, the multi-directional catheter further includes a first connection portion 700 and a second connection portion 800; wherein the first connection portion 700 is the connection surface between the first tube body 400 and the second tube body 500, and the second connection portion 800 is the connection surface between the second tube body 500 and the third tube body 600.

[0037] For a better understanding of the bending direction of the bending portion 300 in this embodiment, the first tube body 400 extends along the A direction, the second tube body 500 extends along the B direction, and the third tube body 600 extends along the C direction, and the A direction, B direction, and C direction are the axes of the multi-directional catheter. The A direction is a straight line on the horizontal plane, the B direction is also on the horizontal plane and has a bend to the left or right. After the C direction is connected to the B direction, while bending downward in the vertical plane, it also bends to the left or right on the horizontal plane. It should be noted that the bending direction of the B direction can be to the left or to the right, and this left and right are relative to Figure 3 the plane projection in Figure 4 the vertical plane projection, and of course, left and right in the figure are down and up, and in space, they are left and right relative to the second tube body 500.

[0038] Further, in this embodiment, a preferred solution is that in the projection on the horizontal plane of the first tube body 400 and the third tube body 600, the bending angle between the two is 140 degrees. In the projection on the horizontal plane of the second tube body 500, it is an arc with a radius of 76.2 mm from the tube axis to the center of the circle. In the projection on the horizontal plane of the first connection portion 700 and the second connection portion 800, the surface angle between the two is 40 degrees.

[0039] In this embodiment, the lower end portion 200 further includes an opening portion 201. After the opening portion 201 is connected to the bottom of the third tube body 600, the length downward along its extending direction is 10 mm, and the diameter of the opening portion 201 gradually increases.

[0040] Embodiment 3

[0041] Refer to Figures 6 - 7For illustration purposes, in this embodiment, it shows the application of the multi-directional catheter in a pipe dredging machine. The multi-directional catheter is applied to the inner cylinder 900 of the pipe dredging machine. The opening part 201 is embedded in the opening 901 at the edge of the inner cylinder 900. The upper end part 100 of the first pipe body 400 extends out from the pipe orifice of the inner cylinder 900. Therefore, the bottom of the third pipe body 600 has a tangential transition with the outside of the drum, which can effectively prevent the soft shaft from knotting. The inner cylinder 900 is inside the drum 1000. The space formed after the inner cylinder 900 and the drum 1000 are sleeved is used to store the soft shaft. The soft shaft is distributed on the side wall of the inner cylinder 900, enters through the opening part 201, and is discharged after passing through the bending part 300.

[0042] Generally speaking, the catheter is placed as close as possible to the outside of the drum 1000, so that the soft shaft can be stored in a smaller space, restricting the twisting space of the soft shaft and preventing knotting. The traditional catheter has only one bend in the radial direction from the center of the drum. If it is close to the outside of the drum, the soft shaft cannot immediately coil within a small radius range. Therefore, it cannot be placed too close to the outside of the drum, leaving redundant space for the soft shaft to coil, and thus leaving potential space for the soft shaft to knot. In this embodiment, the original bend in the radial direction from the center of the drum 1000 is changed in advance to a tangential transition with the outside of the drum 1000.

[0043] It should be noted that the pipe dredging machine mentioned in this embodiment is only an example for the installation and application of the multi-directional hose. The pipe dredging machine necessarily includes driving structures, power components, circuit arrangements, electronic components, and relative working control modules and other similar modules, as well as how the pipe dredging machine realizes the output and discharge of the soft shaft, etc. The above technical means are non-essential technical features of this embodiment and are completely irrelevant to the technical problems to be solved in this embodiment. Referring to the implicit disclosure, those skilled in the art can fully implement them in combination with the existing technology and common knowledge, so no detailed description will be given.

[0044] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. The embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention, and any reference signs in the claims should not be regarded as limiting the claims involved.

[0045] It should also be understood that the present utility model is described through implementation manners.

Therefore, when judging whether the technical solutions described in the specification of the present utility model are fully disclosed, the core meaning of the solutions defined by the claims should be fully considered. And there must be other technical problems in the specification that are irrelevant to the core technical problems solved by the present embodiment.
