Description

Technical Field

[0001] This utility model relates to a daily necessities, specifically a drum-type pipe cleaning machine. Background Technology

[0002] A drum-type drain cleaner is a type of pipe cleaning tool. It primarily uses a motor to drive a drum, which in turn drives an internal flexible shaft to rotate, gradually conveying debris outwards. The end of the flexible shaft then wraps around and cleans objects inside the pipe. Currently, the drive mechanisms in drum-type drain cleaners, such as the motor and belt, are existing, mature structures with limited optimization and innovation. The focus is mainly on optimizing components within the drum, such as how to make the flexible shaft output faster, how to prevent the shaft from easily tangling inside the drum, and how to reduce the overall cost of the drain cleaner. The tendency for the flexible shaft to tangle inside the drum is due to a larger gap between the inner lining and the inner wall of the flexible shaft box. Additionally, existing drain cleaners, due to their numerous components, may exhibit complexity and higher costs. Utility Model Content

[0003] The purpose of this utility model is to provide a drum-type pipe cleaning machine, and the technical problem to be solved is: how to avoid the flexible shaft from getting tangled inside the drum shell while optimizing the structure of the cleaning machine and thus reducing the cost of the entire cleaning machine.

[0004] A drum-type pipe cleaning machine includes a drum box, a fixed sleeve, a guide tube, a rotating bushing, and an inner liner. The drum box is hollow inside and has two openings on opposite sides. The fixed sleeve is tightly fitted against the inner wall of the drum box and covers one of the two openings. The fixed sleeve is hollow inside and has the guide tube fitted inside at its axis. The guide tube is arc-shaped and hollow inside, with a curved surface at its end to facilitate the output and retraction of the flexible shaft. The rotating bushing has a guide groove at the position where it mates with the guide tube. This guide groove passes through a hole at the axis of the rotating bushing, and the rotating bushing is shaft-connected to a bearing. The inner liner is fixed to the drum box. The outer walls of the fixed sleeve, rotating bushing, and inner liner are aligned with each other.

[0005] The diameter of one of the two openings of the drum box is smaller than the diameter of the other opening; the smaller opening is fitted with a fixing sleeve, and the outer diameter of the fixing sleeve is larger than the smaller opening.

[0006] The drum box has a perforated hole next to the smaller opening.

[0007] The fixing sleeve has a screw hole on the side of the hollow interior, and the outer wall of the drum box also has a screw hole at the corresponding position. The drum box has an end cap at the opening with a smaller diameter. The end cap has a stud. The screw passes through the screw hole on the fixing sleeve, the screw hole on the outer wall of the drum box, and engages with the stud on the end cap.

[0008] The fixing sleeve is a hollow disc shape.

[0009] The guide tube is J-shaped, with one end penetrating the hollow part inside the fixing sleeve and end cap.

[0010] The rotating bushing has an outwardly protruding extension in the direction of the inner lining, and the extension is sleeved with a bearing and connected to the round rod shaft of the drum-type pipe cleaning machine.

[0011] The inner lining is recessed inward and corresponds to the shape of the extension of the rotating bushing. An inner fixing part is formed by extending longitudinally at the recess and is assembled with the cylinder.

[0012] The liner has a radiating internal fixing plate structure inside.

[0013] The liner has an external fixing part at the edge position, which is fixedly assembled to the drum box by bolts.

[0014] The beneficial effects of this utility model are as follows: by configuring a fixed sleeve between the drum box and the rotating bushing, the position is filled, avoiding the knotting problem caused by the flexible shaft due to the gap at this position; at the same time, by designing the rotating bushing to be assembled with the round rod only through the bearing, the stiffness of rotation is greatly reduced, making it more flexible and ensuring the smooth rotation of the flexible shaft; by designing the outer walls of the fixed sleeve, rotating bushing, and inner liner to be close to or consistent with each other, a stepped structure will not be formed to jam the flexible shaft; by designing the inner liner as a one-piece piece, the existing structure of inner liner plus fixed plate is replaced, which makes the structure simpler and the cost lower.

[0035] Please refer to Figures 1 to 7 The drum-type pipe cleaning machine shown in the figure mainly consists of a drum box 7, an end cap 1, a fixing sleeve 3, a guide tube 2, a rotating bushing 4, an inner liner 5, a flexible shaft 8, a bearing 9, a motor 10, a bracket 11, and a round rod 12. The drum box 7 houses the other components and, when driven by the motor 10 and belt, drives the flexible shaft 8 to either convey it outwards or inwards. The end cap 1 covers the outward-facing opening 72 of the drum box 7 and fixes the guide tube 2. The fixing sleeve 3 fills the gap between the inner wall of the drum box 7 and the rotating bushing 4 to prevent the flexible shaft 8 from getting stuck in the gap. The guide tube 2 guides the flexible shaft 8 to convey it outwards or inwards. The rotating bushing 4 fixes the guide tube 2 and facilitates its rotation. The inner liner 5 works with the round rod to connect the rotating bushing 4 to the rotating bushing 4 using the bearing 9. The flexible shaft 8 serves as the cleaning component of the entire cleaning machine. The motor 10 drives the drum box 7 to rotate via a belt. The bracket 11 fixes and supports the other components. The above only describes the main functions of each component. Other functions of each component can be further explained and expanded with reference to the accompanying drawings. In practical applications, the above components can be redesigned for optimization, additional components can be added, or existing components can be replaced with equivalent ones as needed.

[0036] The drum housing 7 in the figure is a cylindrical structure made of sheet metal. Its hollow interior creates a large internal space to accommodate components such as the flexible shaft 8, fixing sleeve 3, rotating bushing 4, and inner liner 5. The drum housing 7 has two openings 72, one at the top (outward-facing) and one at the bottom (inward-facing), forming a two-opening structure. The diameter of the top opening 72 is smaller than that of the bottom opening 72. Symmetrically arranged perforated holes 71 are also designed next to the top opening 72 to facilitate penetration into the drum housing 7 and other user operations. An end cap 1 covers the outside of the top opening 72, and a fixing sleeve 3 covers the inside of the top opening 72. These caps are for mutual fixation, and the specific fixing methods can vary, such as using bolts and screws.

[0037] The end cap 1 in the figure is a flat-topped conical structure with a hollow centerline to facilitate the passage of the guide tube 2. Multiple studs 11 are designed on its inner side, facing the fixing sleeve 3, to facilitate subsequent screw assembly. The screws pass through the fixing sleeve 3 and the outer wall of the drum box 7 and are then fixed to the studs 11. The lateral area of ​​the inner side of the end cap 1 is larger than the diameter of the corresponding opening 72 of the drum box 7 to achieve coverage. To reduce manufacturing costs, the end cap 1 can be integrally molded from one side using plastic.

[0038] The fixing sleeve 3 in the figure has a disc-like structure. It is hollow inside, and its axis is positioned to facilitate the passage of the guide tube 2. Its top covers the corresponding opening 72 of the drum box 7 and fits snugly against the inner wall of the drum box 7. The fixing sleeve 3 has multiple screw holes 31 at its hollow edge, which align with the corresponding screw holes 31 on the outer wall of the drum box 7. This facilitates the passage of bolts for later installation, allowing for connection with the studs 11 of the end cap 1. To reduce manufacturing costs, the fixing sleeve 3 can be integrally molded from one side using plastic.

[0039] The guide tube 2 in the figure adopts a J-shaped arc structure, with a hollow interior to facilitate the passage of the flexible shaft 8. At the initial entry end of the flexible shaft 8, a curved surface 21 is designed, resembling a trumpet, which facilitates the output and retraction of the flexible shaft 8. Correspondingly, its other end is tubular and passes through the hollow interior of the fixing sleeve 3 and end cap 1. To reduce manufacturing costs, the guide tube 2 can be integrally molded from one side using plastic.

[0040] In the figure, the rotating bushing 4 extends inward from its side wall to form a guide groove 41, which facilitates the placement of the assembly guide tube 2. The initial position of the guide groove 41 is on the side wall of the rotating bushing 4, and the end position is at the axis of the rotating bushing 4, thus achieving through-hole connection between the guide groove 41 and the axis of the rotating bushing 4, ensuring that one end of the guide tube 2 is at the axis of the rotating bushing 4, the fixed sleeve 3, and the end cap 1. To ensure smooth rotation of the rotating bushing 4 without jamming, the rotating bushing 4 is designed with an outwardly protruding extension 42 structure towards the inner lining 5. A bearing 9 can be fitted onto this extension 42, allowing for shaft connection with the round rod 12 on the drum-type pipe cleaning machine. In this way, the rotation of the rotating bushing 4 is only restricted by the bearing 9, and it is not assembled with other components, thus ensuring that there will be no jamming problem due to assembly. To reduce manufacturing costs, the rotating bushing 4 can be integrally molded from one side using plastic. In order to cover the top of the extension 42, an inner cap 6 can be designed to seal its internal cavity. The inner cap 6 is the structure of a conventional plastic cap or lid.

[0041] The inner liner 5 is recessed inward to accommodate the extension 42 of the rotating bushing 4. To fix the cylinder, a longitudinally extending structure can be designed in the recess to form an inner fixing part 51. To strengthen the extension 42, a radiating inner fixing piece 52 structure can be designed. For easy fixing to the outer wall of the drum housing 7, the inner liner 5 has multiple outer fixing parts 53 at its edges. These outer fixing parts 53 can be fixed to the outer wall of the drum housing 7 with bolts and screws and rotate in conjunction. To prevent the inner liner 5, rotating bushing 4, and fixing sleeve 3 from forming a stepped structure that causes the flexible shaft 8 to tangle due to inconsistent radial lengths, the outer walls of the fixing sleeve 3, rotating bushing 4, and inner liner 5 can be designed to align with each other, ensuring that none of them will snag on the flexible shaft 8. To reduce manufacturing costs, the inner liner 5 can be integrally molded from one side using plastic.

[0042] The components in the figure, such as the motor 10, bracket 11, and round rod 12, can all be made from existing drum-type pipe cleaning machine accessories or adapted to existing accessories without creative modifications. The above-mentioned components and their assembly and functional relationships with other components are all existing technologies.
