[0073] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0074] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0075] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects before and after are in an "and / or" relationship.

[0076] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0077] In this application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, etc. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0078] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0079] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0080] The present application provides a pipe cleaner, which is a handheld device capable of releasing and recovering a cable 300. The cable 300 is a main component for cleaning and unblocking the pipe. The pipe cleaner gradually releases the cable 300 so that the cable 300 moves in the pipe. The moving cable 300 can drive the blockage in the pipe to move, thereby achieving the purpose of cleaning and unblocking the pipe. In some embodiments, the diameter of the cable 300 adapted by the pipe cleaner is 6mm-14mm, for example, the diameter of the cable 300 can be 1 / 4 inch, 5 / 16 inch or 3 / 8 inch.

[0081] The pipe cleaner has a feeding function, a recycling function and a locking function. The feeding function enables the feeding of the cable 300. Under the feeding recycling function, the cable 300 can be output outward along the first direction X. The recycling function enables the recycling of the cable 300. Under the recycling recycling function, the cable 300 can be recycled inward along the first direction X. The locking function enables the locking of the cable 300, so that the cable 300 cannot move along the first direction X, and thus cannot fall out of the main structure of the pipe cleaner.

[0082] like Figures 1 to 37 As shown, the pipe cleaner includes a first handle 100, a drum 200, a cable 300, a drive assembly 400 and a feeding assembly 500. The first handle 100 is used for the user to hold. The drum 200 is connected to the first handle 100. The drum 200 is the main installation component of the pipe cleaner, and the cable 300 is at least partially stored in the drum 200. The drive assembly 400 is used to drive the drum 200 to rotate, thereby providing power for the feeding and recovery of the cable 300. The feeding assembly 500 is used to feed or recover the cable 300, and has an outlet 511 for outputting the cable 300. The output end of the cable 300 extends outward from the outlet 511 along a first direction X. The feeding assembly 500 includes a plurality of rotating bodies 501 arranged around the cable 300 and a rotating mechanism 5010 capable of rotating around the first direction X (see Figure 7 ), the rotating mechanism 5010 is configured to drive the multiple rotating bodies 501 to move synchronously in a direction close to the cable 300 or synchronously in a direction away from the cable 300 when rotating around the first direction X.

[0083] Due to the diversity of the locations of pipes, pipe cleaners need to be used at different angles, such as from top to bottom, from bottom to top, or tilted, etc. Compared with the pipe cleaners in the prior art that use downward pressure to drive the rotating body, the method of rotating the rotating body is more in line with the user's operating habits. In actual use, the user can easily change the position of the rotating body by holding the first handle 100 with one hand and rotating the rotating mechanism 5010 with the other hand. Therefore, the pipe cleaner provided in the embodiment of the present application is highly versatile, easy to operate, and suitable for different cleaning scenarios, which is convenient for users to operate at multiple angles to clean and dredge pipes.

[0084] The specific structure of each component of the pipe cleaner is described in detail below with reference to the accompanying drawings.

[0085] The first handle 100 is a component for a user to hold the pipe cleaner. Figures 1 to 4 As shown, the first handle 100 is arranged at the rear of the entire pipe cleaner along the first direction X. In order to facilitate holding and protect the user's hands, the first handle 100 is formed into a closed ring structure. Specifically, the first handle 100 includes a gripping portion, an upper connecting portion, a lower connecting portion and an assembly portion, wherein the gripping portion is arranged behind the assembly portion along the first direction X, and the upper connecting portion and the lower connecting portion are both connected between the gripping portion and the assembly portion. The gripping portion is provided with an anti-slip pattern structure for increasing friction, and an installation cavity for installing the drive assembly 400 is formed in the assembly portion. A trigger 101 is provided on the inner side of the gripping portion, and pressing the trigger 101 can power on the entire pipe cleaner and start working.

[0086] In some embodiments, in order to enable the user to hold the pipe cleaner with both hands, Figure 32 to Figure 34 As shown, the pipe cleaner further includes a second handle 1100, which is disposed on the shield 700. Figure 5 As shown, along the first direction X, the shield 700 is arranged at the front side of the first handle 100. The specific structure of the shield 700 will be described in detail below. The second handle 1100 is convexly arranged above the shield 700. When the user operates the pipe cleaner, one hand holds the first handle 100 and the other hand holds the second handle 1100, which greatly improves the stability of holding.

[0087] A cavity for accommodating the cable 300 is formed in the drum 200, and most of the cable 300 is coiled in the cavity. In some embodiments, such as Figure 5As shown, a support cone 230 in the shape of a cone is formed in the drum 200, and most of the cable 300 is wound on the support cone 230, and the central axis of the support cone 230 is parallel to the first direction X. The front end of the first handle 100 is connected to the drum 200, and the drum 200 can rotate relative to the front end of the first handle 100 around an axis parallel to the first direction X. During the rotation of the drum 200, the cable 300 wound on the support cone 230 is gradually released or gradually recovered. A through hole is formed at the front end of the drum 200 to allow the cable 300 to pass through.

[0088] In some embodiments, Figure 5 As shown, there is a gap L1 between the end of the roller 200 and the first handle 100, and L1 is greater than or equal to 1 mm. In some embodiments, the diameter of the cable 300 adapted to the pipe cleaner is 6 mm-14 mm, for example, the diameter of the cable 300 can be 1 / 4 inch, 5 / 16 inch or 3 / 8 inch.

[0089] The driving assembly 400 includes a motor and a transmission assembly. The drum 200 is connected to the motor through the transmission assembly. Under the drive of the motor and through the transmission of the transmission assembly, power can be provided for the rotation of the drum 200. It should be noted that the specific structure of the transmission assembly is prior art and can be directly selected according to the prior art. The structure of the transmission assembly is not limited here.

[0090] like Figure 4 and Figure 5 As shown, the pipe cleaner further includes a shield 700, which is disposed outside the drum 200. The shield 700 does not interfere with the drum 200 during operation, so that the outer wall of the rotating drum 200 does not contact the external structure or the user's hand. The provision of the shield 700 can improve the safety of the pipe cleaner. It should be noted that the shield 700 may be connected to the first handle 100 or may not be connected to the first handle 100.

[0091] In some embodiments, Figure 4 As shown, a base 740 is formed at the bottom end of the shield 700. Figure 5 When the pipe cleaner is held at the angle shown, the base 740 can be supported on a support surface provided by an external device or placed directly on the ground, thereby reducing the weight of the pipe cleaner borne by the user.

[0092] In some embodiments, Figure 2As shown, a mounting sleeve 710 is formed at the front end of the shield 700 , and the mounting sleeve 710 is cylindrical. The output end of the drum 200 extends into the mounting sleeve 710 , and the direction of the central axis of the mounting sleeve 710 is parallel to the first direction X. In some specific embodiments, the mounting sleeve 710 can assume the function of mounting the feeding assembly 500 .

[0093] In some embodiments, a rear opening is formed on the shield 700, and the first handle 100 is located at the rear side of the rear opening. Such a configuration simplifies the assembly of the shield 700 and the drum 200 and facilitates heat dissipation of the drum 200.

[0094] In some embodiments, a support and positioning structure is provided on the inner wall surface of the shield 700, and the support and positioning structure is in sliding contact with the outer wall surface of the drum 200. Figure 5 As shown, the support and positioning structure is a steel ball 760; in some other specific embodiments, the support and positioning structure is a bearing. Further, a plurality of steel balls 760 are arranged on the inner wall surface of the shield 700, and the plurality of steel balls 760 are evenly distributed along the circumference of the shield 700, thereby improving the support stability of the shield 700.

[0095] In some embodiments, Figure 3 As shown, a disassembly hole 770 is provided on the front end surface of the shield 700, and the disassembly hole 770 is arranged opposite to the connecting piece on the drum 200. Fig.34 As shown, the drum 200 includes a cylinder 210 and a guide cover 220, and the cylinder 210 and the guide cover 220 are fixed by a connecting piece, and the connecting piece can be a screw. The disassembly hole 770 provided on the shield 700 is arranged opposite to the connecting piece, and the connecting piece can be directly disassembled from the cylinder 210 and the guide cover 220 through the disassembly hole 770, so that the cable 300 can be replaced without disassembling the shield 700. Further, the number of the connecting pieces is multiple, and correspondingly, the number of the disassembly holes 770 is also multiple, and the multiple disassembly holes 770 and the multiple connecting pieces are arranged one by one.

[0096] In some embodiments, the cable 300 is not disposed in the drum 200, but is wound outside the drum 200, and a space for accommodating the cable 300 is formed between the inner wall surface of the shield 700 and the outer wall surface of the drum 200. In order to reduce the damage caused to the shield 700 by the cable 300 during the release or recovery process, as shown in FIG. Fig.30 and Fig.31As shown, a plurality of roller bodies 800 are arranged in the shield 700, and the roller bodies 800 are extended in a direction parallel to the first direction X. The plurality of roller bodies 800 are arranged along the circumference of the shield 700, and each roller body 800 is rotatably connected in the shield 700 through a bearing, so that rolling friction is formed between the cable 300 and the roller body 800. When the drum 200 rotates, the cable 300 is wound around the outer wall surface of the drum 200 under the action of the recovery force. In this process, the roller body 800 replaces the shield 700 to bear the wear, so that the shield 700 is not easily worn.

[0097] In some specific embodiments, the distance between the roller body 800 and the drum 200 is equal to the diameter of the cable 300 , so that only one layer of the cable 300 can be coiled between the inner wall of the shield 700 and the outer wall of the drum 200 .

[0098] In some specific embodiments, the shield 700 includes a cylindrical rear shield 750 and a conical front shield 720. Correspondingly, the drum 200 includes a cylindrical body 210 and a conical guide shield 220. The guide shield 220 is sleeved in the front shield 720. The small-sized end of the guide shield 220 is formed with an inlet and outlet for allowing the cable 300 to enter and exit. The guide shield 220 can rotate with the body 210 and can play a role in isolating the friction between the cable 300 and the front shield 720. Further, a pressure ring 730 is provided between the rear shield 750 and the front shield 720.

[0099] In some embodiments, Fig.34 As shown, the front end of the guide cover 220 of the drum 200 is open to form a drum mouth 221, and the opening size of the drum mouth 221 is much larger than the diameter of the cable 300, so that not only the cable 300 can be smoothly replaced through the drum mouth 221, but also there is no need to remove the rear cover 750 during cleaning. The drum 200 can be cleaned through the drum mouth 221 only after removing the front cover 720.

[0100] The feeding assembly 500 is the main component of the pipe cleaner to realize the feeding and recovery function. In the present application, the feeding speed of the feeding assembly 500 is 0-0.2 m / s. The feeding assembly 500 makes it unnecessary to hold the handle when feeding or recovering the cable 300, and the handle will not hit the hand during operation, thereby improving the safety of the pipe cleaner.

[0101] like Figures 1 to 8 One embodiment of a feed assembly 500 is shown.

[0102] Specifically, the feeding assembly 500 includes a guide 502 and a clamping assembly 520. The clamping assembly 520 includes the rotating body 501 described above. The guide 502 can provide a guide for the movement of the clamping assembly 520. The clamping assembly 520 can move on the guide 502 to clamp or loosen the cable 300. The rotating mechanism 5010 includes a feeding collar 503. The guide 502 is provided with a guide groove 5023. The feeding collar 503 is provided with a slide groove 5031. The clamping assembly 520 is slidably connected in the guide groove 5023, and the clamping assembly 520 can move along the slide groove 5031.

[0103] It should be noted that the slide groove 5031 here can be an involute groove, a linear groove or an irregular curve groove, as long as the distances from the starting point and the end point of the slide groove 5031 to the rotation center of the feed collar 503 are different. Since the clamping assembly 520 can move along the slide groove 5031, the distance between the clamping assembly 520 and the rotation center of the feed collar 503 changes during the movement, and since there is a limit of the guide groove 5023, the rotating feed collar 503 can make the clamping assembly 520 move in the guide groove 5023, and the clamping assembly 520 can clamp or loosen the cable 300 according to the different rotation directions of the feed collar 503.

[0104] In some embodiments, Figure 6 As shown, the guide member 502 includes a mounting portion 5021 and a guide rail portion 5022. A first mounting hole 5032 is provided at the center of the feed collar 503. The mounting portion 5021 is inserted into the first mounting hole 5032 and can rotate in the first mounting hole 5032, thereby realizing the rotational connection between the guide member 502 and the feed collar 503. The guide rail portion 5022 is provided with the above-mentioned guide groove 5023, and the extension direction of the guide groove 5023 is parallel to the radial direction of the feed collar 503.

[0105] In some embodiments, continue to refer to Figure 6 As shown, the clamping assembly 520 also includes a support frame 504, which is movably disposed in the guide groove 5023, and both ends of the support frame 504 are protruded from the outside of the guide groove 5023, and one end of the support frame 504 is provided with a second pulley 5041, and the second pulley 5041 can move in the slide groove 5031, and the other end of the support frame 504 is used to install the rotating body 501.

[0106] In some embodiments, there are multiple, for example, three, clamping components 520 , guide grooves 5023 , and slide grooves 5031 , and they are arranged in one-to-one correspondence, which can improve the clamping strength and clamping stability of the clamping component 520 on the cable 300 . Specifically, the guide member 502 includes a mounting portion 5021 and a plurality of guide rail portions 5022 arranged around the mounting portion 5021, the feed collar 503 is rotatably sleeved on the mounting portion 5021, each guide rail portion 5022 has a radial guide groove 5023 parallel to the feed collar 503, the feed collar 503 is provided with a slide groove 5031 corresponding to the guide groove 5023 one by one, the plurality of slide grooves 5031 are circumferentially arranged around the first mounting hole 5032, the plurality of support frames 504 are slidably connected in the plurality of guide grooves 5023 one by one, and the second pulley 5041 arranged at one end of each support frame 504 can move in the corresponding slide groove 5031, and a rotating body 501 is installed at the other end of each support frame 504.

[0107] In addition to directly rotating the feed ring 503 to tighten or loosen the cable 300, the user can also achieve this by driving an external structural member relatively fixed to the feed ring 503. In some embodiments, Figure 5 As shown, the feeding assembly 500 also includes an operating sleeve 510, and the user can clamp or loosen the clamping assembly 520 by operating the operating sleeve 510. Specifically, the guide 502, the clamping assembly 520 and the feeding collar 503 are all located in the operating sleeve 510, and the rotation of the operating sleeve 510 can drive the feeding collar 503 to rotate.

[0108] In some embodiments, the locking force of the operating sleeve 510 can withstand the weight of the tool itself (about 7 kg), so that the operating sleeve 510 is not easy to be unlocked.

[0109] In some embodiments, the operating sleeve 510 is rotatably sleeved on the outside of the output end of the drum 200 and sleeved on the outside of the installation sleeve 710 , and the outlet 511 is formed at the front end of the operating sleeve 510 .

[0110] In some specific embodiments, in order to achieve relative fixation between the feed collar 503 and the operating sleeve 510, the outer wall surface of the feed collar 503 and the inner wall surface of the operating sleeve 510 are limitedly abutted, so that rotating the operating sleeve 510 can drive the feed collar 503 to rotate synchronously. Figure 6As shown, the feed collar 503 is roughly disc-shaped, and a first limiting plane 5033 is arranged on the arc-shaped outer wall surface of the feed collar 503. The number of the first limiting planes 5033 can be set to multiple according to the needs. The first limiting plane 5033 forms a flat position. Correspondingly, a second limiting plane is arranged on the arc-shaped inner wall surface of the operating sleeve 510. The second limiting plane is in surface contact with the first limiting plane 5033, so as to play a role of mutual limiting. Of course, the feed collar 503 and the operating sleeve 510 can also be relatively fixed by other methods, such as screw connection, clamping, etc.

[0111] like Figures 9 to 25 Two additional embodiments of pipe cleaner feed assemblies 500 are shown.

[0112] Specifically, the feeding assembly 500 includes a rotating body 501 and a feeding block 505, wherein the feeding block 505 is used to install the rotating body 501, and the feeding block 505 is movably placed in the operating sleeve 510 along the radial direction of the operating sleeve 510. Correspondingly, an involute boss 512 is circumferentially arranged on the inner wall surface of the operating sleeve 510, and the involute boss 512 is arranged around the cable 300. The feeding block 505 is slidably abutted on the involute arc surface of the involute boss 512, and the user drives the feeding assembly 500 to clamp or loosen by operating the operating sleeve 510.

[0113] When the user rotates the operating sleeve 510, the involute boss 512 moves accordingly, causing the position of the involute boss 512 abutting against the feed block 505 to change. Since the distances from the central axis of the cable 300 at different locations on the involute arc surface of the involute boss 512 are different, the change in the abutment point can drive the feed block 505 to move radially along the operating sleeve 510, thereby causing the rotating body 501 to move toward or away from the cable 300, thereby achieving clamping or loosening of the cable 300.

[0114] In some embodiments, the side of the feed block 505 away from the operating sleeve 510 is used to install the rotating body 501, and the side of the feed block 505 close to the operating sleeve 510 is used to install the abutment body, which slides and abuts on the involute arc surface of the involute boss 512.

[0115] In some specific embodiments, Fig.15 As shown, the abutting body is a roller 5051 , and the roller 5051 is rotatably connected to the feed block 505 .

[0116] In some other embodiments, such as Fig. 22 As shown, the abutment body is a protrusion 5054 , and the end of the protrusion 5054 away from the feed block 505 has an arc abutment surface.

[0117] In some embodiments, the feed block 505 is a closed frame structure, and the feed block 505 includes two oppositely arranged fan-shaped plates and two oppositely arranged rectangular plates. A mounting cavity with an opening size gradually increasing from the inside to the outside is formed in the feed block 505, and part of the structure of the rotating body 501 is placed in the mounting cavity. Of course, in other embodiments, the shape of the feed block 505 can be adjusted according to needs, as long as it is ensured that multiple feed blocks 505 do not interfere when approaching the cable 300 synchronously. It should be noted that the three rotating bodies 501 are installed on the three feed blocks 505 at an angle of 120° to each other.

[0118] In order to limit the moving direction of the feed block 505, so that the feed block 505 can only move along the radial direction of the operating sleeve 510, as shown in FIG. Fig.24 As shown, the feeding assembly 500 further includes a limiting disk 506, which is disposed in the operating sleeve 510. The limiting disk 506 is provided with a plurality of limiting holes 5061, each of which is provided along the radial extension of the limiting disk 506, and each of the feeding blocks 505 is provided with a guide post 5055, which is inserted into the limiting holes 5061 one by one and can move in the limiting holes 5061. In some embodiments, the disk surface of the limiting disk 506 is disposed perpendicular to the first direction X.

[0119] In addition to setting the limit plate 506, it is also possible to Fig.10 and Fig.11 As shown, a plurality of guide grooves 712 are radially provided on the mounting sleeve 710, a first pulley 5052 is provided on each feed block 505, the first pulley 5052 is slidably connected in the guide groove 712, and an avoidance hole 711 is opened on the mounting sleeve 710 to allow the abutment body to pass through.

[0120] In some specific embodiments, the number of feed blocks 505 is three, and three avoidance holes 711 are opened on the mounting sleeve 710. The three avoidance holes 711 are arranged one-to-one corresponding to the three feed blocks 505. Two first pulleys 5052 are arranged on each feed block 505. The two first pulleys 5052 are arranged at both ends of the feed block 505 perpendicular to its moving direction. Correspondingly, six guide grooves 712 are arranged on the mounting sleeve 710. The six guide grooves 712 are grouped in pairs, and each group of guide grooves 712 includes two guide grooves 712 respectively arranged on both sides of an avoidance hole 711, and the six first pulleys 5052 are slidingly connected in the six guide grooves 712 one-to-one.

[0121] Furthermore, if Fig.15As shown, the feed assembly 500 also includes a connecting spring 5053, and a connecting spring 5053 is arranged between two adjacent feed blocks 505. When the multiple feed blocks 505 move in the direction of clamping the cable 300, the connecting spring 5053 is compressed and accumulates elastic potential energy. When the multiple feed blocks 505 move in the direction of loosening the cable 300, the connecting spring 5053 releases the elastic potential energy, so that the feed blocks 505 can move faster.

[0122] In some embodiments, the feed assembly 500 further includes a plurality of guide rods, at least one guide rod is disposed between two adjacent feed blocks 505, one end of the guide rod is fixed on one feed block 505, and the other end is passed through another adjacent feed block 505, and the guide rod is parallel to the tangent direction of the cable 300. When the plurality of feed blocks 505 synchronously move toward the direction of approaching the cable 300, the spacing between the two adjacent feed blocks 505 becomes smaller and smaller, and the guide rod provides a guiding effect for the two feed blocks 505 to approach each other, thereby improving the moving accuracy; and when the plurality of feed blocks 505 synchronously move toward the direction of moving away from the cable 300, the spacing between the two adjacent feed blocks 505 becomes larger and larger, and the guide rod provides a guiding effect for the two feed blocks 505 to move away from each other, thereby improving the moving accuracy.

[0123] The locking assembly 600 is the main component of the pipe cleaner to realize the locking function. The locking assembly 600 can lock the position of the cable 300 so that the cable 300 does not move along the first direction X. It should be noted in advance that the operating sleeve 510 can move relative to the mounting sleeve 710 along the first direction X after being rotated to a set angle. The locking assembly 600 moving along the first direction X can lock the cable 300. In order to realize the change of the state between the operating sleeve 510 and the mounting sleeve 710, an arc-shaped first limit block is provided on the inner wall surface of the operating sleeve 510, and a limit groove is provided on the first limit block along the circumferential direction. A second limit block is provided on the outer wall surface of the mounting sleeve 710. When it is not necessary to lock the cable 300, the second limit block is limited in the limit groove. When it is necessary to perform the locking function, the operating sleeve 510 is rotated so that the second limit block is disengaged from the limit groove to release the clamping state. At this time, the operating sleeve 510 is moved along the first direction X again to drive the locking assembly 600 to act.

[0124] Figures 1 to 5 One embodiment of a locking assembly 600 is shown.

[0125] Specifically, the locking assembly 600 includes a moving part capable of moving along a first direction X and a locking spring piece 602. The operating sleeve 510 is fixedly arranged with the moving part. The operating sleeve 510 moving along the first direction X can drive the moving part to move synchronously along the first direction X. The moving part moving along the first direction X can squeeze the locking spring piece 602 to deform and cause the locking end of the locking spring piece 602 to clamp the cable 300.

[0126] In some embodiments, the moving member includes a locking collar 601, which is sleeved in the operating sleeve 510 and fixedly connected to the operating sleeve 510, and the fixed connection method includes but is not limited to clamping, connecting with a connector, etc. In some specific embodiments, the locking collar 601 is located in the installation sleeve 710, and a fixing plate 6012 is radially protruded outward on the outer wall surface of the locking collar 601, and a corresponding position of the installation sleeve 710 is provided with an avoidance through hole 713, and the fixing plate 6012 passes through the avoidance through hole 713 and is clamped with a fixing groove provided on the inner wall surface of the operating sleeve 510, so that the locking collar 601 can move synchronously with the operating sleeve 510.

[0127] In some embodiments, the locking spring sheet 602 is a bent sheet structure, one end of the locking spring sheet 602 is a clamping end, and the other end is an abutting end, the abutting end of the locking spring sheet 602 abuts against the inner wall surface of the locking collar 601, and the clamping end is provided with a clamping groove, which is a semicircular groove. When the locking collar 601 moves along the first direction X, it can squeeze the locking spring sheet 602 to deform it, so that the clamping groove is clamped on the outer wall surface of the cable 300, thereby fixing the position of the cable 300 and preventing it from entering or exiting.

[0128] Furthermore, in order to reduce the wear of the locking spring sheet 602 on the inner wall surface of the locking ring 601, increase the service life of the locking ring 601, and make the locking ring 601 have higher rotation flexibility, the movable part also includes a locking bearing 603, and the locking bearing 603 is sleeved in the locking ring 601. The locking bearing 603 is arranged around the cable 300, and the abutting end of the locking spring sheet 602 abuts against the inner ring of the locking bearing 603. The locking bearing 603 can move along the locking ring 601 along the first direction X, so that the locking spring sheet 602 is deformed and locks the cable 300.

[0129] In some more specific embodiments, Fig.29As shown, the locking collar 601 includes two half collars 6011 arranged opposite to each other, and the two half collars 6011 are spliced ​​to form the locking collar 601. Each half collar 6011 is provided with a receiving ring groove on one side facing the other half collar 6011, and the two receiving ring grooves are spliced ​​to form a space for accommodating and limiting the outer ring of the locking bearing 603. Further, a plurality of fixing plates 6012 are convexly provided on the outer wall surface of each half collar 6011, for example, two, and the plurality of fixing plates 6012 are spaced apart and distributed in the circumferential direction of the half collar 6011.

[0130] In some embodiments, there are multiple locking spring sheets 602, and the multiple locking spring sheets 602 are arranged circumferentially around the cable 300. The locking bearing 603 and the locking ring 601 moving along the first direction X can simultaneously drive the multiple locking spring sheets 602 to deform, so that the clamping ends of the multiple locking spring sheets 602 lock the cable 300 at the same time.

[0131] Figure 26 to Figure 28 Another embodiment of a locking assembly 600 is shown.

[0132] The locking assembly 600 includes a moving member, a fixed seat 607 and a plurality of clamping arms 608. The moving member can move along a first direction X. One end of the clamping arm 608 is rotatably connected to the fixed seat 607. The cable 300 is arranged through the fixed seat 607. The moving member moving along the first direction X can drive the plurality of clamping arms 608 to rotate synchronously toward the direction close to the cable 300 to clamp the cable 300. It should be noted that the specific structure of the moving member has been introduced above, so it will not be repeated here.

[0133] In some embodiments, there are two clamp arms 608. Each clamp arm 608 includes a first arm 6081 and a second arm 6082 connected at an obtuse angle, the length of the first arm 6081 is smaller than the length of the second arm 6082, a rotating shaft block 6083 is provided at one end of the first arm 6081 away from the second arm 6082, and a first rotating shaft hole 60831 is provided through the rotating shaft block 6083. Correspondingly, a rotating shaft seat is provided on the fixed seat 607, and the rotating shaft seat includes two rotating shaft plates 6071 arranged at intervals, each rotating shaft plate 6071 is provided with two second rotating shaft holes 60711, and a gap for accommodating the rotating shaft block 6083 is formed between the two rotating shaft plates 6071, and a rotating shaft 609 is passed through each of the two second rotating shaft holes 60711 and one first rotating shaft hole 60831, so as to realize the rotation connection between the two clamp arms 608 and the fixed seat 607. In some specific embodiments, a ball bearing is disposed in the first shaft hole 60831 , and the shaft 609 passing through the ball bearing can improve the flexibility of the clamp arm 608 in rotation.

[0134] In some more specific embodiments, a clamping plate 6084 is protruded on the outer wall surface of the connection between the first arm 6081 and the second arm 6082, and an arc-shaped clamping surface is provided on the clamping plate 6084. When the clamping arm 608 moves toward the direction close to the cable 300, the arc-shaped clamping surface can be clamped on the outer wall surface of the cable 300, thereby improving the clamping stability of the cable 300.

[0135] In some embodiments, the fixed seat 607 includes a seat body 6072 and two limit plates 6073, the rotating shaft seat is protruded on the seat body 6072, the two limit plates 6073 are protruded on the same side of the seat body 6072, and the two limit plates 6073 are arranged opposite to each other at intervals, and the two clamping arms 608 are arranged between the two limit plates 6073. The setting of the limit plates 6073 can limit the two clamping arms 608 to move only in the direction of approaching or moving away from each other.

[0136] Figures 17 to 19 Yet another embodiment of a locking assembly 600 is shown.

[0137] The locking assembly 600 includes a moving part, a locking steel ring 604, a locking piece 605 and a return spring 606. The specific structure of the moving part has been introduced above, so it will not be repeated here. The locking steel ring 604 is sleeved in the locking bearing 603, and the locking steel ring 604 has a conical inner wall surface. The locking piece 605 is movably penetrated on the mounting sleeve 710 along the second direction, and the second direction is perpendicular to the first direction X. One end of the locking piece 605 abuts against the conical inner wall surface. The locking steel ring 604 moving along the first direction X can drive the locking piece 605 to move in a direction close to the cable 300 to clamp the cable 300. The return spring 606 has a tendency to drive the locking piece 605 to move in a direction away from the cable 300.

[0138] In some embodiments, the end surface of the locking end of the locking piece 605 is a concave arc surface, so that the contact area between the locking piece 605 and the cable 300 is increased, thereby improving the locking stability of the cable 300.

[0139] In some embodiments, the abutting end of the locking piece 605 that abuts the conical inner wall surface of the locking steel ring 604 is an arrow-shaped structure, thereby improving the structural strength of the abutting end of the locking piece 605 and preventing the locking piece 605 from deforming during the abutment with the locking steel ring 604.

[0140] In some embodiments, there are multiple sets of locking pieces 605 and return springs 606 . The multiple sets of locking pieces 605 are arranged around the mounting sleeve 710 , and each locking piece 605 is sleeved with a return spring 606 .

[0141] It should be noted that the pipe cleaner provided in the present application provides at least three types of locking assemblies 600 and at least three types of feeding assemblies 500 . The locking assemblies 600 and the feeding assemblies 500 can be freely combined and are not limited to the combinations shown in the drawings.

[0142] The cable 300 will inevitably be contaminated during the process of cleaning and unclogging the pipe. In order to simultaneously clean the cable 300 during the recovery process of the cable 300, so that the cable 300 will not bring contaminants into the pipe cleaner, such as Fig.35 and Fig.36 As shown, the pipe cleaner has a matching cleaning tool. In some embodiments, the cleaning tool includes a scouring pad that is sleeved on the cable 300 and located outside the pipe cleaner.

[0143] Further, in order to avoid the need for manual force to hold the scouring pad, the scouring pad is maintained in a state of surrounding the cable 300, such as Fig.35 and Fig.36 As shown, the cleaning tool also includes a mounting frame 900, which is semi-cylindrical, and a semi-cylindrical receiving groove 910 is formed in the mounting frame 900. The receiving groove 910 has a rectangular opening, and the scouring pad can be bent and inserted into the receiving groove 910 through the rectangular opening. The end plates at the front and rear ends of the mounting frame 900 are formed with through holes that allow the cable 300 to pass through. In order to facilitate the installation of the mounting frame 900 on the cable 300, one end of the through hole passes through the end plate of the mounting frame 900 to form a U-shaped through groove.

[0144] In some embodiments, in order to prevent the scouring pad from detaching from the mounting frame 900, an abutment plate is provided on the inner wall surface of the mounting groove. Since the scouring pad is easy to deform, the provision of the abutment plate will not affect the scouring pad from entering the mounting groove, and can increase the contact area between the mounting frame 900 and the scouring pad, so that the scouring pad can be stably fixed in the mounting frame 900.

[0145] In some embodiments, a baffle is provided at the opening of the mounting groove, and the baffle is arranged horizontally so that the opening size of the mounting groove is appropriately reduced. The scouring pad can be allowed to enter the mounting groove by squeezing it. After the scouring pad enters the mounting groove, the scouring pad rebounds from the inside to the outside and contacts the baffle, making it difficult for the scouring pad to escape from the mounting groove through the opening of the mounting groove.

[0146] In some embodiments, the mounting bracket 900 is detachably connected to the output end of the pipe cleaner outlet 511 through the bayonet 920, so that when cleaning the cable 300, the user does not have to hold the cleaning tool all the time, thereby improving the user's convenience.

[0147] The pipe cleaner can be used to unclog sewers and chimneys. In this usage scenario, the output direction of the cable 300 is generally from top to bottom. Since the length of the cable 300 inside the pipe cleaner cannot be estimated, it is easy for the cable 300 to fall out of the pipe cleaner. In order to prevent the cable 300 from falling out of the pipe cleaner during the release process, Fig.37 As shown, a fastener 1000 is fixed at the end of the cable 300, and a limiting boss 1200 is provided in the mounting sleeve 710. When the end of the cable 300 moves to the limiting boss 1200, the fastener 1000 can abut against the limiting boss 1200, so that the cable 300 can no longer be output outward, thereby preventing the cable 300 from falling out of the pipe cleaner completely.

[0148] In some embodiments, the fastener 1000 is a U-shaped piece made of elastic material. By prying apart the two side walls of the fastener 1000, the fastener 1000 can be sleeved on the cable 300. After the force is stopped, the side walls of the fastener 1000 press against the cable 300. Example

[0149] like Figures 1 to 8 A pipe cleaner is provided as shown. The pipe cleaner includes a first handle 100 , a drum 200 , a cable 300 , a drive assembly 400 , a shield 700 , a feed assembly 500 , and a locking assembly 600 .

[0150] The first handle 100 is used for a user to hold, and is disposed at the rear of the entire pipe cleaner along a first direction X. A trigger 101 is disposed on the first handle 100 .

[0151] The drum 200 is connected to the front of the first handle 100, and the drum 200 forms a cavity for accommodating the cable 300. Specifically, the drum 200 includes a cylinder body 210 and a guide cover 220 connected front and back.

[0152] The driving assembly 400 is used to drive the drum 200 to rotate. The driving assembly 400 specifically includes a motor and a transmission assembly. Driven by the motor and transmitted by the transmission assembly, it can provide power for the rotation of the drum 200. The axis of rotation of the drum 200 is parallel to the first direction X. During the rotation of the drum 200, the cable 300 wound in the drum 200 is gradually released or gradually recovered.

[0153] The shield 700 is disposed outside the drum 200. The shield 700 does not interfere with the drum 200 during operation, so that the outer wall surface of the rotating drum 200 does not contact the external structure or the user's hand. The shield 700 can improve the safety of the pipe cleaner. Specifically, the shield 700 includes a front shield 720 and a rear shield 750. The bottom end of the shield 700 is formed with a base 740. The front end of the rear shield 750 forms a mounting sleeve 710. The rear end of the rear shield 750 forms a rear opening for exposing the drum 200. A plurality of steel balls 760 are arranged on the inner wall surface of the shield 700. A disassembly hole 770 is arranged on the front end surface of the shield 700.

[0154] The feeding assembly 500 is used to feed or recycle the cable 300. The feeding assembly 500 has an outlet 511 for outputting the cable 300. The output end of the cable 300 extends outward from the outlet 511 along the first direction X. Specifically, the feeding assembly 500 includes a rotating mechanism 5010, a guide 502, and a plurality of clamping assemblies 520. The rotating mechanism 5010 includes a feeding collar 503 and an operating sleeve 510. The feeding collar 503 is roughly disc-shaped, and the feeding collar 503 is arranged in the operating sleeve 510. A first limiting plane 5033 is arranged on the arc-shaped outer wall surface of the feeding collar 503, and a second limiting plane is arranged on the arc-shaped inner wall surface of the operating sleeve 510. The second limiting plane is in surface contact with the first limiting plane 5033, so that rotating the operating sleeve 510 can rotate the feeding collar 503. The feed collar 503 is provided with a first mounting hole 5032 located at the center and three slide grooves 5031 arranged circumferentially around the first center hole, and the slide grooves 5031 are involute grooves. The guide member 502 can provide a guide for the movement of the clamping assembly 520, and the guide member 502 includes a mounting portion 5021 and three guide rail portions 5022 evenly distributed along the circumference of the mounting portion 5021. The mounting portion 5021 is inserted into the first mounting hole 5032 and can rotate in the first mounting hole 5032. A through hole is provided at the center of the mounting portion 5021 to allow the cable 300 to pass through, and each guide rail portion 5022 is provided with a linear guide groove 5023, and the extension direction of the guide groove 5023 is parallel to the radial direction of the cable 300. The clamping assembly 520 includes a support frame 504 and a rotating body 501. The support frame 504 is movably arranged in the guide groove 5023. Both ends of the support frame 504 are protruded on the outside of the guide groove 5023. One end of the support frame 504 is provided with a second pulley 5041, and the second pulley 5041 can move in the slide groove 5031. The other end of the support frame 504 is installed with a rotating body 501. The three rotating bodies 501 are arranged around the cable 300 and are used to correct the feeding angle of the cable 300.

[0155] When the operating sleeve 510 is rotated, the feed ring 503 can rotate synchronously with the operating sleeve 510. Through the cooperation of the slide groove 5031 and the second pulley 5041, the support frame 504 can move along the corresponding guide groove 5023, so that the multiple rotating bodies 501 move towards or away from the cable 300 at the same time to lock or release the cable 300.

[0156] The locking assembly 600 includes a moving part that can move along the first direction X and a locking spring sheet 602. The moving part includes a locking collar 601 and a locking bearing 603 located in the operating sleeve 510. A fixing plate 6012 is radially protruded outward on the outer wall surface of the locking collar 601. A corresponding position of the mounting sleeve 710 is provided with an avoidance through hole 713. The fixing plate 6012 passes through the avoidance through hole 713 and is engaged with a fixing groove provided on the inner wall surface of the operating sleeve 510, so that the locking collar 601 can move synchronously with the operating sleeve 510. The locking collar 601 includes two relatively arranged half collars 6011. The two half collars 6011 are spliced ​​to form the locking collar 601. Each half collar 6011 is provided with an accommodating ring groove on one side facing the other half collar 6011. The two accommodating ring grooves are spliced ​​to form a space for accommodating and limiting the outer ring of the locking bearing 603. The locking bearing 603 is arranged around the cable 300. The locking spring sheet 602 is a bent sheet structure, one end of the locking spring sheet 602 is a clamping end, and the other end is an abutting end. The abutting end of the locking spring sheet 602 abuts against the inner wall surface of the locking bearing 603, and the clamping end is provided with a clamping groove, which is a semicircular groove.

[0157] The operating sleeve 510 moving along the first direction X can drive the moving part to move synchronously along the first direction X. The moving part moving along the first direction X can squeeze the locking spring piece 602 to deform, so that the locking groove of the locking spring piece 602 is clamped on the outer wall surface of the cable 300, so that the locking end of the locking spring piece 602 clamps the cable 300, and the position of the cable 300 remains fixed and cannot enter or exit. Example

[0158] like Figures 9 to 19 A pipe cleaner is provided. The main difference between the pipe cleaner and the pipe cleaner provided in the first embodiment lies in a feeding assembly 500 and a locking assembly 600 .

[0159] Specifically, the feeding assembly 500 of this embodiment includes a rotating mechanism 5010, a feeding block 505 and a rotating body 501. The rotating mechanism 5010 is an operating sleeve 510, and an involute boss 512 is circumferentially arranged on the inner wall surface of the operating sleeve 510. There are three involute bosses 512 arranged around the cable 300. There are three feed blocks 505, which are evenly distributed around the circumference of the cable 300, and each feed block 505 is movably placed in the operating sleeve 510 along the radial direction of the operating sleeve 510. A rotating body 501 is installed on the side of each feed block 505 away from the operating sleeve 510, and an abutment body is provided on the side of each feed block 505 close to the operating sleeve 510. In the present embodiment, the abutment body is a roller 5051, and three avoidance holes 711 are opened on the mounting sleeve 710. The three rollers 5051 respectively pass through the three avoidance holes 711 and slide and abut on the involute arc surface of the corresponding involute boss 512.

[0160] Two first pulleys 5052 are provided on each feed block 505, and the two first pulleys 5052 are arranged at both ends of the feed block 505 perpendicular to its moving direction. Correspondingly, six guide grooves 712 are provided on the mounting sleeve 710, and the six guide grooves 712 are grouped in pairs. Each group of guide grooves 712 includes two guide grooves 712 respectively arranged on both sides of an avoidance hole 711, and the six first pulleys 5052 are slidably connected in the six guide grooves 712 one by one.

[0161] The feeding assembly 500 also includes three connecting springs 5053. A connecting spring 5053 is arranged between two adjacent feeding blocks 505. When the three feeding blocks 505 move in the direction of clamping the cable 300, the connecting springs 5053 are compressed and accumulate elastic potential energy. When the three feeding blocks 505 move in the direction of loosening the cable 300, the connecting springs 5053 release the elastic potential energy, so that the feeding blocks 505 can move faster.

[0162] The feeding assembly 500 further includes three guide rods, one of which is provided between two adjacent feeding blocks 505, one end of which is fixed on one feeding block 505, and the other end of which is passed through another adjacent feeding block 505, and the guide rod is parallel to the tangent direction of the cable 300. When the multiple feeding blocks 505 synchronously move toward the direction of approaching the cable 300, the distance between the two adjacent feeding blocks 505 becomes smaller and smaller, and the guide rod provides a guiding function for the two feeding blocks 505 to approach each other, thereby improving the moving accuracy; and when the multiple feeding blocks 505 synchronously move toward the direction of moving away from the cable 300, the distance between the two adjacent feeding blocks 505 becomes larger and larger, and the guide rod provides a guiding function for the two feeding blocks 505 to move away from each other, thereby improving the moving accuracy.

[0163] When the user rotates the operating sleeve 510, the involute boss 512 moves accordingly, causing the position of the involute boss 512 abutting against the roller 5051 to change. Since the distances between the involute arc surface of the involute boss 512 and the central axis of the cable 300 are different at different locations, under the limiting action of the first pulley 5052 and the guide groove 712, the change of the abutment point of the roller 5051 against the involute boss 512 can drive the three feed blocks 505 to move synchronously along the radial direction of the operating sleeve 510, thereby causing the three rotating bodies 501 to move toward or away from the cable 300, thereby achieving clamping or loosening of the cable 300.

[0164] The locking assembly 600 includes a moving part, a locking steel ring 604, a locking piece 605 and a return spring 606. The moving part includes a locking collar 601 and a locking bearing 603. The locking steel ring 604 is sleeved in the locking bearing 603. The locking steel ring 604 has a conical inner wall surface. The locking piece 605 is movably arranged on the mounting sleeve 710 along the second direction, and the second direction is perpendicular to the first direction X. One end of the locking piece 605 abuts against the conical inner wall surface, and the end surface of the other end of the locking piece 605 is a concave arc surface. The locking steel ring 604 moving along the first direction X can drive the locking piece 605 to move in a direction close to the cable 300 to clamp the cable 300. The return spring 606 has a tendency to drive the locking piece 605 to move in a direction away from the cable 300. The number of the locking pieces 605 and the return spring 606 is multiple groups, and the multiple groups of locking pieces 605 are arranged around the mounting sleeve 710. A return spring 606 is sleeved on each locking piece 605. Example

[0165] like Figures 20 to 29 A pipe cleaner is provided. The main difference between the pipe cleaner and the pipe cleaners provided in the first and second embodiments is the feeding assembly 500 and the locking assembly 600 .

[0166] Specifically, in this embodiment, the feeding assembly 500 includes a rotating mechanism 5010, a feeding block 505, a rotating body 501 and a limiting plate 506. The rotating mechanism 5010 is an operating sleeve 510, and an involute boss 512 is circumferentially arranged on the inner wall surface of the operating sleeve 510, and the number of the involute boss 512 is three and is arranged around the cable 300. There are three feed blocks 505, which are evenly distributed around the circumference of the cable 300, and each feed block 505 is movably placed in the operating sleeve 510 along the radial direction of the operating sleeve 510. A rotating body 501 is installed on the side of each feed block 505 away from the operating sleeve 510, and an abutment body is provided on the side of each feed block 505 close to the operating sleeve 510. In the present embodiment, the abutment body is a protrusion 5054, and three avoidance holes 711 are opened on the mounting sleeve 710. The three protrusions 5054 respectively pass through the three avoidance holes 711 and slide and abut on the involute arc surface of the corresponding involute boss 512.

[0167] The disk surface of the limiting disk 506 is arranged perpendicular to the first direction X. There are two limiting disks 506, which are arranged in the operating sleeve 510 and located on both sides of the three feeding blocks 505. Each limiting disk 506 is provided with three limiting holes 5061, and each limiting hole 5061 is arranged to extend along the radial direction of the limiting disk 506. Two guide posts 5055 are arranged on each feeding block 505, and the two guide posts 5055 are respectively arranged at two opposite ends of the feeding block 505. The two guide posts 5055 are inserted into the limiting holes 5061 at corresponding positions in the two limiting disks 506 in a one-to-one correspondence, and the guide posts 5055 can move in the limiting holes 5061.

[0168] The feeding assembly 500 also includes three connecting springs 5053. A connecting spring 5053 is arranged between two adjacent feeding blocks 505. When the three feeding blocks 505 move in the direction of clamping the cable 300, the connecting springs 5053 are compressed and accumulate elastic potential energy. When the three feeding blocks 505 move in the direction of loosening the cable 300, the connecting springs 5053 release the elastic potential energy, so that the feeding blocks 505 can move faster.

[0169] The feeding assembly 500 further includes three guide rods, one of which is provided between two adjacent feeding blocks 505, one end of which is fixed on one feeding block 505, and the other end of which is passed through another adjacent feeding block 505, and the guide rod is parallel to the tangent direction of the cable 300. When the multiple feeding blocks 505 synchronously move toward the direction of approaching the cable 300, the distance between the two adjacent feeding blocks 505 becomes smaller and smaller, and the guide rod provides a guiding function for the two feeding blocks 505 to approach each other, thereby improving the moving accuracy; and when the multiple feeding blocks 505 synchronously move toward the direction of moving away from the cable 300, the distance between the two adjacent feeding blocks 505 becomes larger and larger, and the guide rod provides a guiding function for the two feeding blocks 505 to move away from each other, thereby improving the moving accuracy.

[0170] When the user rotates the operating sleeve 510, the involute boss 512 moves accordingly, causing the position of the involute boss 512 abutting against the protrusion 5054 to change. Since the distances between the involute arc surface of the involute boss 512 and the central axis of the cable 300 are different at different locations, under the limiting action of the limiting plate 506 and the limiting hole 5061, the change in the abutment point of the protrusion 5054 against the involute boss 512 can drive the three feed blocks 505 to move synchronously along the radial direction of the operating sleeve 510, thereby causing the three rotating bodies 501 to move toward or away from the cable 300, thereby achieving clamping or loosening of the cable 300.

[0171] The locking assembly 600 includes a moving member, a fixed seat 607 and two clamping arms 608. The moving member includes a locking collar 601 and a locking bearing 603 that can move along a first direction X. Each clamp arm 608 includes a first arm 6081 and a second arm 6082 connected at an obtuse angle, the length of the first arm 6081 is shorter than the length of the second arm 6082, a shaft block 6083 is provided at one end of the first arm 6081 away from the second arm 6082, a first shaft hole 60831 is provided through the shaft block 6083, a shaft seat is provided on the fixed seat 607, the shaft seat includes two shaft plates 6071 arranged at intervals, each shaft plate 6071 is provided with two second shaft holes 60711, a gap is formed between the two shaft plates 6071 to accommodate the shaft block 6083, a shaft 609 is provided through each of the two second shaft holes 60711 and one first shaft hole 60831, so as to realize the rotation connection between the two clamp arms 608 and the fixed seat 607. The cable 300 is provided through the fixed seat 607 and is located between the two clamp arms 608. A clamping plate 6084 is convexly provided on the outer wall surface of the connection between the first arm 6081 and the second arm 6082, and an arc-shaped clamping surface is provided on the clamping plate 6084.

[0172] The moving member moving along the first direction X can drive multiple clamping arms 608 to rotate synchronously toward the direction close to the cable 300 to clamp the cable 300. When the clamping arms 608 move toward the direction close to the cable 300, the arc-shaped clamping surface can be clamped on the outer wall surface of the cable 300, thereby locking the cable 300.

[0173] In combination with the feeding assembly 500 disclosed in the first, second and third embodiments, their common feature is that the rotating body 501 arranged around the cable 300 approaches or moves away from the cable 300 by means of a rotating mechanism 5010 rotating around the first direction X, and both the slide groove 5031 disclosed in the first embodiment and the involute boss 512 applied in the second and third embodiments provide an arc-shaped motion trajectory for the rotating body 501. In other words, in addition to its own rotation, the entire rotating body 501 also moves along an arc-shaped trajectory, that is, the center of mass of the rotating body 501 moves along an arc-shaped trajectory. More specifically, the center of mass of the rotating body 501 moves along an involute-shaped motion trajectory. With such a configuration, when the user operates the operating sleeve 510 in a circumferential direction (such as rotating), the feeding of the cable 300 can be realized, and the operation is simple and convenient, the stability is high, and it is not easy to fail. Example

[0174] like Fig.30 and Fig.31 A pipe cleaner is provided. The difference between the pipe cleaner provided in this embodiment and the pipe cleaner provided in the first to third embodiments mainly lies in the protective cover 700 and the roller 200.

[0175] Specifically, in this embodiment, the cable 300 is not arranged in the drum 200, but is wound outside the drum 200, and a space for accommodating the cable 300 is formed between the inner wall surface of the shield 700 and the outer wall surface of the drum 200. The shield 700 includes a front shield 720, a pressure ring 730 and a rear shield 750 connected in sequence from front to back, and 12 roller bodies 800 are arranged in the shield 700, and the roller bodies 800 extend in a direction parallel to the first direction X. The 12 roller bodies 800 are arranged along the circumference of the shield 700, and each roller body 800 is rotatably connected in the shield 700 through a bearing, so that rolling friction is formed between the cable 300 and the roller body 800. The size of the spacing between the roller body 800 and the drum 200 is equal to the diameter of the cable 300, so that only one layer of the cable 300 can be wound between the inner wall surface of the shield 700 and the outer wall surface of the drum 200.

[0176] When the drum 200 rotates, the cable 300 is wound around the outer wall surface of the drum 200 under the action of the recovery force. In this process, the roller body 800 takes the wear instead of the shield 700, so that the shield 700 is not easily worn. Example

[0177] like Figure 32 to Figure 34 A pipe cleaner is provided. The pipe cleaner provided in this embodiment differs from the pipe cleaners provided in Embodiments 1 to 4 mainly in a handle and a roller 200 .

[0178] Specifically, in the present embodiment, the pipe cleaner includes two handles, namely a first handle 100 and a second handle 1100 . The first handle 100 is disposed at the rear end of the entire pipe cleaner, and the second handle 1100 is disposed on the protective cover 700 .

[0179] The front end of the guide cover 220 of the drum 200 is open to form a drum mouth 221, and the opening size of the drum mouth 221 is much larger than the diameter of the cable 300, so that not only the cable 300 can be smoothly replaced through the drum mouth 221, but also there is no need to remove the rear cover 750 during cleaning. The drum 200 can be cleaned through the drum mouth 221 only after removing the front cover 720. Example

[0180] like Figure 35 to Figure 37 A pipe cleaner is provided. The pipe cleaner provided in this embodiment is different from the pipe cleaners provided in Embodiments 1 to 5 in that this embodiment further includes a cleaning tool and a fastener 1000.

[0181] Specifically, in this embodiment, the cleaning tool includes a mounting frame 900 and a scouring pad. The mounting frame 900 is semi-cylindrical, and a semi-cylindrical receiving groove 910 is formed in the mounting frame 900. The receiving groove 910 has a rectangular opening, and an abutment plate is provided on the inner wall surface of the mounting groove, and a baffle is provided at the opening of the mounting groove. The scouring pad can be bent and inserted into the receiving groove 910 through the rectangular opening, and the end plates at the front and rear ends of the mounting frame 900 are formed with through holes for allowing the cable 300 to pass through.

[0182] The cable 300 can pass through the scouring pad and be cleaned by the scouring pad during the recycling process, so that the cable 300 entering the pipe cleaner is in a clean state, avoiding the contaminated cable 300 from bringing contaminants into the pipe cleaner.

[0183] A clip 1000 is also fixed at the end of the cable 300, and a limiting boss 1200 is provided in the installation sleeve 710. When the end of the cable 300 moves to the limiting boss 1200, the clip 1000 can abut against the limiting boss 1200, so that the cable 300 can no longer be output outward, so that the cable 300 will not fall out of the pipe cleaner. The clip 1000 is a U-shaped piece made of elastic material. By breaking open the two side walls of the clip 1000, the clip 1000 can be sleeved on the cable 300. After the force is stopped, the side walls of the clip 1000 press against the cable 300.

[0184] The pipe cleaner can be used to unclog sewers and chimneys. In this usage scenario, the output direction of the cable 300 is generally from top to bottom. Since the length of the cable 300 inside the pipe cleaner cannot be estimated, it is easy for the cable 300 to fall out of the pipe cleaner completely. The coupling member 1000 and the limiting boss 1200 are arranged in cooperation to prevent the cable 300 from falling out of the pipe cleaner during the release process. Example

[0185] like Figures 38 to 43 A feeding assembly 500 of a pipe cleaner is provided, the feeding assembly 500 comprises a plurality of rotating bodies 501 arranged around a cable and a rotating mechanism 5010 capable of rotating around a first direction X. When the rotating mechanism 5010 rotates around the first direction X, the plurality of rotating bodies 501 can be driven to move synchronously in a direction close to the cable or synchronously in a direction away from the cable. The first direction X is parallel to the front-rear direction of the pipe cleaner, and the first direction X here is Figure 5 The first direction X is shown. The solution described in the seventh embodiment is an expansion of the structure of the feeding assembly 500 in the third embodiment. The technical principle of the seventh embodiment can be applied to solutions similar to those in the first embodiment, the second embodiment or other embodiments.

[0186] The feeding assembly 500 includes a mounting sleeve 530, a clamping assembly 520 and an operating sleeve 510. The operating sleeve 510 is sleeved outside the mounting sleeve 530, and the clamping assembly 520 is arranged inside the mounting sleeve 530. Part of the structure of the clamping assembly 520 protrudes from the mounting sleeve 530 and abuts against the operating sleeve 510. The operating sleeve 510 is the above-mentioned rotating mechanism 5010, and the clamping assembly 520 includes a feeding block 505 and the above-mentioned rotating body 501.

[0187] Specifically, the installation sleeve 530 is cylindrical, the output end of the cable 300 extends into the installation sleeve 530, and the direction of the central axis of the installation sleeve 530 is parallel to the first direction X. Fig.44 and Fig.45As shown, an involute boss 512 is provided along the circumferential direction on the inner wall surface of the operating sleeve 510, and the number of the involute bosses 512 is three and they are arranged around the cable. The number of the feed blocks 505 is three, and the three feed blocks 505 are evenly distributed around the circumference of the cable, and each feed block 505 is movably placed in the operating sleeve 510 along the radial direction of the operating sleeve 510, and a rotating body 501 is installed on the side of each feed block 505 away from the operating sleeve 510, and an abutment body is provided on the side of each feed block 505 close to the operating sleeve 510.

[0188] Continue to refer to Fig.49 As shown, the pipe cleaner includes a hose 600 and a feed assembly 500. The feed assembly 500 is used to feed or recycle cables. The feed assembly 500 has an input port for the cables to enter. The front end of the shield 700 is formed with an output port 511 for the cables to output. The hose 600 is connected between the input port and the output port 511, and the hose 600 allows the cables to pass through.

[0189] like Figure 46 to Figure 48 As shown, in some embodiments, the abutment body is a protrusion 5054 , and three avoidance holes 531 are opened on the mounting sleeve 530 . The three protrusions 5054 respectively pass through the three avoidance holes 531 and slide and abut on the involute arc surface of the corresponding involute boss 512 .

[0190] Continue to refer to Figure 46 to Figure 48 As shown, the clamping assembly 520 further includes a limiting disk 506, the disk surface of which is arranged perpendicular to the first direction. There are two limiting disks 506, which are arranged in the operating sleeve 510 and located on both sides of the three feeding blocks 505. Each limiting disk 506 is provided with three limiting holes 5061, and each limiting hole 5061 is arranged to extend radially along the limiting disk 506. Two guide posts 5055 are arranged on each feeding block 505, and the two guide posts 5055 are respectively arranged at two opposite ends of the feeding block 505. The two guide posts 5055 are inserted into the limiting holes 5061 at corresponding positions in the two limiting disks 506 in a one-to-one correspondence, and the guide posts 5055 can move in the limiting holes 5061.

[0191] Continue to refer to Fig.48 As shown, the feed assembly 500 also includes three connecting springs 5053. A connecting spring 5053 is arranged between two adjacent feed blocks 505. When the three feed blocks 505 move in the direction of clamping the cables, the connecting springs 5053 are compressed and accumulate elastic potential energy. When the three feed blocks 505 move in the direction of loosening the cables, the connecting springs 5053 release the elastic potential energy, so that the feed blocks 505 can move faster.

[0192] The feed assembly 500 also includes three guide rods, one of which is provided between two adjacent feed blocks 505, one end of which is fixed on one feed block 505, and the other end is passed through another adjacent feed block 505, and the guide rod is parallel to the tangent direction of the cable. When multiple feed blocks 505 move synchronously toward the direction of approaching the cable, the distance between two adjacent feed blocks 505 becomes smaller and smaller, and the guide rod provides a guiding effect for the two feed blocks 505 to approach each other, thereby improving the moving accuracy; and when multiple feed blocks 505 move synchronously toward the direction of moving away from the cable, the distance between two adjacent feed blocks 505 becomes larger and larger, and the guide rod provides a guiding effect for the two feed blocks 505 to move away from each other, thereby improving the moving accuracy.

[0193] When the user rotates the operating sleeve 510, the involute boss 512 moves accordingly, causing the position of the involute boss 512 abutting against the protrusion 5054 to change. Since the distances between the involute arc surface of the involute boss 512 and the central axis of the cable are different, under the limiting action of the limiting plate 506 and the limiting hole 5061, the change of the abutment point of the protrusion 5054 against the involute boss 512 can drive the three feed blocks 505 to move synchronously along the radial direction of the operating sleeve 510, thereby causing the three rotating bodies 501 to move toward or away from the cable, thereby achieving clamping or loosening of the cable.

[0194] It should be noted that in the related art, the feeding action and the retrieving action of the cable are switched by changing the direction of the motor. For floor-standing pipe cleaners, users usually use a foot pedal switch to control the start and stop of the appliance and the switching of the direction. The user holds the handle, which is far away from the foot pedal, and the user's operation is extremely inconvenient.

[0195] In an embodiment of the present application, in order to achieve switching between the cable feeding action and the recovery action without changing the direction of the motor, the present application is provided with two groups of clamping assemblies 520, and the two groups of clamping assemblies 520 are arranged at intervals in the front and rear directions of the mounting sleeve 530, and have the same structure. The only difference is that the orientation of the rotating body 501 included in each group of clamping assemblies 520 is different.

[0196] For the convenience of description, the two groups of clamping assemblies 520 are named as feeding clamping assembly 521 and recovery clamping assembly 522 respectively. The rotating body 501 included in the feeding clamping assembly 521 is a first rotating body 5011, and the rotating body 501 included in the recovery clamping assembly 522 is a second rotating body 5012. A plurality of first rotating bodies 5011 are distributed around the circumference of the cable 300, and a plurality of second rotating bodies 5012 are distributed around the circumference of the cable 300. The first rotating body 5011 and the second rotating body 5012 can drive the cable 300 to move in opposite directions. When the first rotating body 5011 presses the cable 300 and starts the motor, the cable 300 moves in the first direction X to achieve the feeding of the cable 300; when the second rotating body 5012 presses the cable 300 and starts the motor, the cable 300 moves in the opposite direction of the first direction X to achieve the recovery of the cable 300.

[0197] Specifically, the number of the first rotating bodies 5011 is three, and the three first rotating bodies 5011 are evenly spaced around the circumference of the cable, and the number of the second rotating bodies 5012 is three, and the three second rotating bodies 5012 are evenly spaced around the circumference of the cable. The three first rotating bodies 5011 and the three second rotating bodies 5012 are arranged in a group of two rows, and the first rotating bodies 5011 and the second rotating bodies 5012 included in each group are arranged opposite to each other in the front-to-back direction of the mounting sleeve 530.

[0198] Correspondingly, two groups of involute bosses 512 are arranged at intervals along the front-to-back direction on the inner wall surface of the operating sleeve 510, each group of involute bosses 512 includes three involute bosses 512 evenly distributed along the circumference of the operating sleeve 510, and the involute bosses 512 included in the two groups of involute bosses 512 are staggered, and the involute arc surfaces of different groups of involute bosses 512 have different inclination directions. The three first rotating bodies 5011 abut against the three involute bosses 512 included in one group of involute bosses 512, and the three second rotating bodies 5012 abut against the three involute bosses 512 included in the other group of involute bosses 512.

[0199] The three first rotating bodies 5011 and the three second rotating bodies 5012 can alternately clamp the cables by rotating the operating sleeve 510. When the three first rotating bodies 5011 included in the feeding clamping assembly 521 clamp the cables, the cables can perform a feeding action, i.e., the outer side of the pipe cleaner is output; when the three second rotating bodies 5012 included in the recovery clamping assembly 522 clamp the cables, the cables can perform a recovery action, i.e., the inner side of the pipe cleaner is recovered. The user can change the rotation direction of the rotating operating sleeve 510 to enable the clamping assembly 520 to realize the feeding function or the recovery function.

[0200] In some embodiments, the length of the entire feeding assembly 500 in the front-to-back direction is 200 mm, the length of the operating sleeve 510 in the front-to-back direction is 115 mm, the outer diameter of the operating sleeve 510 is 68 mm, and the outer diameter of the installation sleeve 530 is 45 mm. Example

[0201] like Figures 49 to 53 As shown, in a new embodiment, the pipe cleaner provided by the present application includes a drum 200, a cable 300, a drive assembly 400, a shield 700 and a window 310. The drum 200 is the main installation component of the pipe cleaner, and a storage space is formed inside the drum 200. The cable is at least partially stored in the storage space, and the portion of the cable placed in the storage space is generally in a coiled state. The drive assembly 400 is used to drive the drum 200 to rotate, thereby providing power for feeding or retrieving the cable.

[0202] The shield 700 is arranged outside the drum 200 to play a protective role.
