[0027] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0028] An embodiment of the present invention provides a portable pipe cleaning machine that can solve the problems described in the background art, which will be described in detail below.

[0029] Please refer to Figures 1 to 4 The portable pipe cleaning machine includes a body 1, a flexible shaft 606, and a sewage collection assembly 9. The body 1 is provided with a fixed shaft assembly 2 and a movable shaft assembly 3, which are spaced apart in the same direction. A clutch clamping assembly 4 is provided between the fixed shaft assembly 2 and the movable shaft assembly 3. The flexible shaft 606 passes through the movable shaft assembly 3, the clutch clamping assembly 4, and the fixed shaft assembly 2 in sequence. The movable shaft assembly 3 can move and press the clutch clamping assembly 4 against the fixed shaft assembly 2, so that the clutch clamping assembly 4 can clamp the flexible shaft 606, thereby facilitating transmission. The sewage collection assembly 9 is connected to the body 1 and includes a collection tray 901, which is located outside the clutch clamping assembly 4 and is used to collect dripping sewage.

[0030] When using this pipe cleaning machine to unclog pipes, the flexible shaft 606 enters the blocked area of ​​the pipe, and the sewage in the pipe flows into the inside of the cleaning machine along the surface of the flexible shaft 606 and drips at the clutch clamping assembly 4. The dripping sewage can be collected by the collection plate 901 set outside the clutch clamping assembly 4, preventing sewage from entering other areas inside the cleaning machine. This ensures that all the components inside the cleaning machine can work together normally, which is beneficial to ensuring the service life of the cleaning machine and ensuring its long-term stable operation.

[0031] The main body 1 provides mounting positions for various components or parts. The main body 1 also includes a left outer shell 101 and a right outer shell 102, which are connected together using screws or bolts. The left and right outer shells 101 and 102 protect the components or parts mounted on the main body 1 and form a complete unit. Support frames 105 are connected around the main body 1, which lift the entire drain cleaning machine off the ground, preventing it from directly contacting the ground when placed on it. A battery 104 is installed within the enclosed space formed by the left and right outer shells 101 and 102. The battery 104 is connected to various electrical components via wires. A switch 103 is located on the outside of either the left or right outer shell 101 or 102, used to start or stop the electrical components.

[0032] The machine body 1 is equipped with a fixed shaft assembly 2, a moving shaft assembly 3, a clutch clamping assembly 4, a handle assembly 5, a swing rod assembly 6, a motor assembly 7, a tensioning mechanism 8, a sewage collection assembly 9, and a flexible shaft cleaning assembly 10.

[0033] The fixed shaft assembly 2 and the movable shaft assembly 3 are arranged sequentially and at intervals along the same straight line. The fixed shaft assembly 2 is fixed to the machine body 1, and the movable shaft assembly 3 is movably arranged on the machine body 1. A clutch clamping assembly 4 is provided between the fixed shaft assembly 2 and the movable shaft assembly 3. A flexible shaft 606 is sequentially inserted between the fixed shaft assembly 2, the clutch clamping assembly 4, and the movable shaft assembly 3. When the movable shaft assembly 3 moves and presses against the clutch clamping assembly 4, the other side of the clutch clamping assembly 4 abuts against the fixed shaft assembly 2 and clamps the flexible shaft 606 inserted inside it. The motor assembly 7 is detachably connected to the fixed shaft assembly 2. Motor assembly 7 can drive the fixed shaft assembly 2 to move, and tensioning mechanism 8 can control the transmission connection or disconnection between motor assembly 7 and fixed shaft assembly 2. Handle assembly 5 is connected to moving shaft assembly 3 through swing rod assembly 6. Rotating handle assembly 5 can drive moving shaft assembly 3 through swing rod assembly 6, so that clutch clamping assembly 4 can clamp flexible shaft 606. Since clutch clamping assembly 4 and fixed shaft assembly 2 are in a tight state, when fixed shaft assembly 2 is driven to rotate by motor assembly 7, it can also drive flexible shaft 606 to rotate through clutch clamping assembly 4, thereby clearing pipes through flexible shaft 606. Sewage collection assembly 9 is used to collect sewage flowing along the pipe during the process of flexible shaft 606 clearing pipes, preventing sewage from entering the inside of the cleaning machine. Flexible shaft cleaning assembly 10 is used to clean solid dirt adhering to flexible shaft 606 to keep flexible shaft 606 clean.

[0034] refer to Figure 4The fixed shaft assembly 2 includes a fixed shaft bracket 201, a first needle roller bearing 202, a first flat bearing 203, a fixed clutch shaft 204, and a large synchronous pulley 205. The fixed clutch shaft 204 is hollow inside, allowing the flexible shaft 606 to pass through. An outer step is provided at one end of the fixed clutch shaft 204 near the clutch clamping assembly 4, and the first flat bearing 203 is provided on the outer step. At the same time, the first needle roller bearing 202 is sleeved on the outside of the fixed clutch shaft 204. The fixed shaft bracket 201 is sleeved on the outside of the first needle roller bearing 202 and abuts against the first flat bearing 203. The fixed shaft bracket 201 and the machine body 1 can be fixedly connected by screws or bolts.

[0035] A groove is provided between the two ends of the fixed clutch shaft 204, and a flat key 207 is fixedly fitted inside the groove. A shaft retaining ring 206 is provided at each end of the flat key 207. The key teeth on the inner side of the large synchronous pulley 205 mesh with the flat key 207 and are simultaneously limited and fixed by the two shaft retaining rings 206. When the large synchronous pulley 205 rotates, it can drive the flat key 207 that meshes with it to rotate, thereby driving the fixed clutch shaft 204 to rotate. Since a first needle roller bearing 202 and a first flat bearing 203 are provided between the fixed shaft support 201 and the fixed clutch shaft 204, the rotation of the fixed clutch shaft 204 will not drive the fixed shaft support 201.

[0036] A deep groove ball bearing 209 is fitted onto the end of the fixed clutch shaft 204 away from the clutch clamping assembly 4. A fixed shaft tail mounting bracket 208 is installed on the outside of the deep groove ball bearing 209. The fixed shaft tail mounting bracket 208 is fixedly connected to the machine body 1, thereby ensuring that the fixed clutch shaft 204 can rotate stably and that the fixed shaft assembly 2 is reliably connected to the machine body 1.

[0037] Continue to refer to Figure 4 The fixed shaft assembly 2 is disposed at one end of the clutch clamping assembly 4, and the movable shaft assembly 3 is disposed at the other end of the clutch clamping assembly 4. The movable shaft assembly 3 can move axially relative to the through flexible shaft 606. The movable shaft assembly 3 includes a movable shaft bracket 301, a sliding bushing 302, an anti-friction sleeve 303, a rotary support sleeve 304, and a movable clutch shaft 305.

[0038] The movable clutch shaft 305 is hollow, allowing the flexible shaft 606 to pass through. A protruding step is provided at one end of the movable clutch shaft 305 near the clutch clamping assembly 4. A second needle roller bearing 306 and a second flat bearing 307 are located at the protruding step. A rotating support sleeve 304 is fitted over the second needle roller bearing 306 and abuts against the second flat bearing 307. A sliding bushing 302 is fitted over the rotating support sleeve 304. A movable shaft bracket 301 is fitted over the sliding bushing 302 and is connected to the machine body 1. The movable clutch shaft 305 can move axially relative to the movable shaft bracket 301. An anti-friction sleeve 303 is also fixed at the tail of the movable shaft bracket 301 to prevent friction and wear between the movable clutch shaft 305 and the movable shaft bracket 301.

[0039] refer to Figure 5 The clutch clamping assembly 4 includes multiple clutch clamping flaps 401 and multiple annular springs 402. The multiple clutch clamping flaps 401 are arranged circumferentially and connected by multiple annular springs 402. A through cavity is formed in the middle of the multiple clutch clamping flaps 401 for the flexible shaft 606 to pass through. The multiple clutch clamping flaps 401 radially press the flexible shaft 606 under the pressure of the end face of the movable clutch shaft 305. In this embodiment, there are three clutch clamping valve blocks 401, which are arranged at equal intervals on the same circumference. There are also three annular springs 402, with both ends of the three annular springs 402 located inside the two adjacent clutch clamping valve blocks 401. In this way, when the three clutch clamping valve blocks 401 are squeezed by external force, they can contract. After the external force is removed, they can rebound and reset under the action of the three compressed annular springs 402, and push the moving clutch shaft 305 to reset. Of course, the clutch clamping valve blocks 401 are provided with an annular cavity inside, and the ends of the annular springs 402 are accommodated in the annular cavity.

[0040] It is worth mentioning that both outer walls of the clutch clamping block 401 are inclined surfaces, and the inner walls of the ends of the movable clutch shaft 305 and the fixed clutch shaft 204 are also inclined surfaces. The inclined outer wall of the clutch clamping block 401 is adapted to the inclined inner wall of the ends of the movable clutch shaft 305 and the fixed clutch shaft 204 to achieve inclined surface contact. When the movable clutch shaft 305 moves towards the fixed clutch shaft 204, it can push the three clutch clamping blocks 401 to move closer to each other and contract, thereby clamping the inserted flexible shaft 606.

[0041] refer to Figure 6 and combined Figure 4 The movement of the movable clutch shaft 305 is driven by the handle assembly 5. The handle assembly 5 is connected to the rotary support sleeve 304 through the swing rod assembly 6. The driving force of the handle assembly 5 is transmitted to the rotary support sleeve 304 through the swing rod assembly 6 to drive the movable clutch shaft 305 to move.

[0042] The swing lever assembly 6 includes a support pin mounting block 601, a swing fork 602, and a lever 605. The support pin mounting block 601 is mounted on the machine body 1 via a support pin 603. The middle part of the swing fork 602 is rotatably mounted on the support pin mounting block 601 via the support pin 603. The first end of the swing fork 602 is connected to one end of the lever 605 via a fixing pin screw 604. The second end of the swing fork 602 is detachably connected to the handle assembly 5. The end of the lever 605 away from the swing fork 602 is fixedly connected to the rotating support sleeve 304 of the moving shaft assembly 3 via a fixing pin screw 604. When the handle assembly 5 drives the swing fork 602 to rotate around the support pin mounting block 601, it can drive the lever 605 to move back and forth. The lever 605 drives the rotating support sleeve 304 to move, which in turn drives the moving clutch shaft 305 to move.

[0043] The handle assembly 5 is detachably connected to the swing fork 602. The handle assembly 5 includes an angled handle block 501 and a handle body 505. One end of the angled handle block 501 has a concave-convex structure, and the second end of the swing fork 602 is provided with a concave-convex groove. The concave-convex structure is inserted into the concave-convex groove and connected by a fixing pin 502, thereby connecting the angled handle block 501 to the second end of the swing fork 602. The handle body 505 and the angled handle block 501 are connected by screws.

[0044] The groove is formed along a direction perpendicular to the axial line of the swing fork 602. An off-axis hole is also formed on the tilt handle block 501. This off-axis hole forms an angle with the axial line of the tilt handle block 501, creating an angle between the axial line of the tilt handle block 501 and the axial line perpendicular to the swing fork 602. When the handle body 505 and the tilt handle block 501 are inserted into the swing fork 602 in the forward direction, the handle body 505 is in a high position, meaning the raised end of the handle body 505 is further away from the body 1. Figure 1 As shown; when the handle body 505 and the tilt handle block 501 are inserted into the swing fork 602 in the opposite direction, the handle body 505 is in a low position, that is, the distance between the raised end of the handle body 505 and the body 1 is closer, such as Figure 10As shown. Different downward pressure distances can be achieved by changing the orientation of the handle body 505 and the tilt handle block 501 in relation to the swing fork 602. For example, when the flexible shaft 606 has a large diameter, since only a small rotation of the handle body 505 is needed to clamp the flexible shaft 606 with the clutch clamping block 401, the handle body 505 and the tilt handle block 501 can be inserted in the opposite direction. When the flexible shaft 606 has a small diameter, since a large rotation of the handle body 505 is needed to clamp the flexible shaft 606 with the clutch clamping block 401, the handle body 505 and the tilt handle block 501 can be inserted in the forward direction. After using the drain cleaning machine, the handle body 505 and the tilt handle block 501 can be inserted in the reverse direction, which saves space and facilitates the transportation and storage of the drain cleaning machine. The handle body 505 and the tilt handle block 501 in this embodiment have two assembly and connection methods, which can adapt to flexible shafts 606 of different sizes and specifications, and increase the portability of the entire drain cleaning machine.

[0045] To prevent slippage when gripping the handle body 505, a rubber sleeve 506 can be wrapped around the outside of the handle body 505 to increase friction. At the same time, the rubber sleeve 506 can also protect the handle body 505. To facilitate the disassembly of the handle body 505 and the tilt handle block 501, a compression spring 503 and a set screw 504 can be installed in the off-axis hole of the tilt handle block 501. The compression spring 503 is located between the fixing pin 502 and the set screw 504, and the set screw 504 is fixed to the compression spring 503. When the end of the handle body 505 presses down on the set screw 504, the compression spring 503 retracts, and then the screw hole on the handle body 505 aligns with the screw hole on the tilt handle block 501. At this time, the handle body 505 and the tilt handle block 501 can be connected together by screws. When the screws connecting the handle body 505 and the tilt handle block 501 are removed, the compressed compression spring 503 rebounds and pops the handle body 505 out, thus separating it from the tilt handle block 501.

[0046] Since the swing fork 602 swings under the drive of the handle assembly 5, in order to ensure the safety and aesthetics of the drain cleaning machine during use and to prevent debris from falling into the machine, the movement of the swing fork 602 is also blocked. Specifically, a cover 607 is connected to the machine body 1. The cover 607 has an elongated hole through which the swing fork 602 passes and can swing within the hole. Guide rail plates 609 are provided on both sides of the elongated hole, forming a fixed guide rail. A sliding plate 608 is slidably mounted on the guide rail. The sliding plate 608 can slide back and forth along the fixed guide rail. The sliding plate 608 has a hole through which the swing fork 602 can pass. In this way, the swing fork 602 will move the sliding plate 608 together with it during the back and forth swinging process, thus blocking the movement of the swing fork 602.

[0047] refer to Figure 6 and Figure 7 The rotational movement of the flexible shaft 606 requires the cooperation of the clutch clamping assembly 4 and the fixed shaft assembly 2. The fixed clutch shaft 204 drives the clutch clamping block 401 to move, and the fixed clutch shaft 204 is driven by the large synchronous pulley 205. The large synchronous pulley 205 is connected to the motor assembly 7 through the synchronous belt 805.

[0048] The motor assembly 7 includes a motor 701, a planetary gearbox 702, and a small synchronous pulley 703. The motor 701 is connected to the planetary gearbox 702, which is connected to the small synchronous pulley 703. The small synchronous pulley 703 is connected to the large synchronous pulley 205 via a synchronous belt 805. The planetary gearbox 702 converts the high speed of the motor 701 to a low speed, which then drives the small synchronous pulley 703 to rotate. The small synchronous pulley 703, in turn, drives the large synchronous pulley 205 to rotate via the synchronous belt 805. When the clutch clamping assembly 4 clamps the flexible shaft 606, the clutch clamping disc 401 abuts against the fixed clutch shaft 204, and the large synchronous pulley 205 drives the fixed clutch shaft 204 to rotate, which in turn drives the flexible shaft 606 to rotate through the clutch clamping disc 401, so as to realize the pipeline dredging operation; of course, when the clutch clamping disc 401 does not clamp the flexible shaft 606, the fixed clutch shaft 204 will still rotate, but will not transmit the rotational torque to the flexible shaft 606.

[0049] Optionally, the motor 701 in this embodiment can be a DC brushless motor 701, and the planetary gearbox 702 can be a commercially available product. The planetary gearbox 702 and the planetary gearbox 702 together with the motor 701 and the small synchronous pulley 703 are common configurations and will not be described in detail here.

[0050] The motor assembly 7 is mounted on the tensioning mechanism 8. The tensioning mechanism 8 adjusts the tension of the synchronous belt 805 on the small synchronous pulley 703 and the large synchronous pulley 205. When the tensioning mechanism 8 tightens the synchronous belt 805 on the small synchronous pulley 703 and the large synchronous pulley 205, the motor assembly 7 and the fixed shaft assembly 2 are connected for transmission, and torque can be reliably transmitted. When the tensioning mechanism 8 does not tighten the synchronous belt 805 on the small synchronous pulley 703 and the large synchronous pulley 205, the transmission between the motor assembly 7 and the fixed shaft assembly 2 is disconnected, and torque cannot be transmitted.

[0051] refer to Figure 7The tensioning mechanism 8 includes a tensioning frame 801, a sliding block 802, a motor fixing plate 804, and a tension adjusting screw 806. The tensioning frame 801 is mounted on the fixed shaft bracket 201. The sliding block 802 is pressed and fixed on the upper and lower adjustment slide rails of the tensioning frame 801 by two fixing screws 803. The motor fixing plate 804 is mounted on the sliding block 802. The motor assembly 7 is fixed together with the motor fixing plate 804 by screws. The tension adjusting screw 806 is set on the tensioning frame 801 and its end abuts against the side of the sliding block 802. When the synchronous belt 805 is not taut on the small synchronous pulley 703 and the large synchronous pulley 205, the fixing screw 803 can be loosened, and the tension adjusting screw 806 can be turned at the same time. The sliding block 802 will be pushed and moved by the tension adjusting screw 806, so that the synchronous belt 805 will be tightened slowly. When the synchronous belt 805 is taut, the fixing screw 803 can be completely tightened. At this time, the motor assembly 7 can achieve transmission with the fixed shaft assembly 2.

[0052] refer to Figure 7 The sewage collection component 9 is installed on the body 1 to collect the sewage flowing downstream of the flexible shaft 606. Since the sewage will flow along the clutch clamping component 4 when the clutch clamping component 4 clamps the flexible shaft 606, the sewage collection component 9 is installed outside the clutch clamping component 4 to facilitate better collection of sewage.

[0053] In this embodiment, the sewage collection assembly 9 includes a collection tray 901 and a guide pipe 902. The collection tray 901 is located below the outside of the clutch clamping assembly 4 and the flexible shaft 606. The collection tray 901 is provided with a guide port. One end of the guide pipe 902 is inserted into the guide port and communicates with the inside of the collection tray 901. The other end of the guide pipe 902 extends to the outside of the casing of the dredging machine, thereby discharging sewage to the outside of the dredging machine and ensuring the cleanliness of the inside of the dredging machine. The casing of the dredging machine is provided with holes through which the guide pipe 902 can pass.

[0054] During the operation of the flexible shaft 606, solid and fluid contaminants may get stuck on the flexible shaft 606. In order to remove solid contaminants or adhering fluid contaminants, a flexible shaft cleaning component 10 can be provided.

[0055] refer to Figure 8 and Figure 9The flexible shaft cleaning assembly 10 is disposed on the body 1. The flexible shaft cleaning assembly 10 includes a connector 1001 and a cleaner 1002. The connector 1001 is connected to the body 1 by screws, and the cleaner 1002 is connected to the connector 1001. The flexible shaft 606 passes through the cleaner 1002. A brush head 1003 is disposed inside the cleaner 1002. When the flexible shaft 606 rotates, the brush head 1003 can brush away dirt on the flexible shaft 606, thereby cleaning the flexible shaft 606. In order to further clean the flexible shaft 606, a water pipe connector 1004 can also be disposed on the side wall of the connector 1001. The water pipe connector 1004 is connected to the inside of the cleaner 1002 and is connected to an external water source to rinse the flexible shaft 606. Of course, water can also be injected into the blocked pipe during the pipe unblocking process through the water pipe connector 1004 to speed up the pipe unblocking.

[0056] The pipe cleaning machine of this embodiment separates the fixed shaft assembly 2 and the moving shaft assembly 3, which reduces the axial dimension while ensuring stable transmission, effectively decreasing the overall axial length of the cleaning machine and resulting in a simpler structure. Furthermore, it includes a sewage collection assembly 9 and a flexible shaft cleaning assembly 10. The sewage collection assembly 9 collects sewage, preventing it from entering the machine, while the flexible shaft cleaning assembly 10 cleans the flexible shaft 606. Additionally, the handle assembly 5 has both forward and reverse assembly states, accommodating flexible shafts 606 of different sizes and specifications while minimizing space requirements.
