Description

Technical Field

[0001] The invention relates to the technical field of pipeline cleaning brushes, and in particular to a detachable and reusable pipeline cleaning brush. Background Art

[0002] The endoscopic biopsy channel is usually a long and narrow channel inside the endoscope, with one end opening near the operating part of the endoscope to facilitate the operator to insert related instruments; the other end extends to the front end of the endoscope, close to the observation site. Different types of endoscopes (such as gastroscopes, colonoscopes, bronchoscopes, etc.) all have biopsy channels, but the specific size and shape will vary depending on the purpose and design of the endoscope.

[0003] Since the biopsy channel is a channel that directly contacts human tissue and various instruments, it needs to be cleaned and disinfected in strict accordance with the specifications after use to prevent cross infection. Generally, a special endoscope cleaning device is used to flush the inside of the channel with a suitable cleaning agent to remove residual tissue debris, blood and other impurities, and then high-level disinfection or sterilization is performed.

[0004] The existing biopsy channel cleaning generally uses a disposable biopsy channel cleaning brush or a reusable biopsy channel cleaning brush. The cleaning part of the reusable biopsy channel cleaning brush is integrated with the rod body and cannot be replaced or disassembled. The rod body has a groove part, which is easy to breed bacteria and difficult to clean. Summary of the invention

[0005] The invention provides a detachable and reusable pipeline cleaning brush, which solves the problem that the cleaning parts of the pipeline cleaning brush in the prior art cannot be replaced.

[0006] The technical solution of the present invention is as follows: a detachable and reusable pipe cleaning brush, comprising: Flexible rods, A cleaning member is detachably arranged on the flexible rod, and the cleaning member is close to one end of the flexible rod.

[0007] As a further technical solution, The flexible rod is provided with an annular groove, and the cleaning member comprises: The elastic sleeve is used for being sleeved in the annular groove, and the outer wall of the elastic sleeve is provided with bristles.

[0008] As a further technical solution, The elastic sleeve is rotatably disposed in the annular groove.

[0009] As a further technical solution, The flexible rod is provided with a cleaning liquid channel, one end of which is an outlet end for introducing cleaning liquid into the vicinity of the cleaning member, and the other end is an inlet end.

[0010] As a further technical solution, it also includes: A conical block is arranged at one end of the flexible rod, the end of the conical block with a smaller diameter is a free end, and the conical block is close to the cleaning member. The conical surface of the conical block is provided with a plurality of cleaning liquid channels, and the cleaning liquid channels are communicated with the outlet end of the cleaning liquid channel.

[0011] As a further technical solution, A plurality of cleaning liquid channels are evenly distributed along the circumference of the conical block.

[0012] As a further technical solution, it also includes: An annular limiting block is arranged on the flexible rod, and the annular groove is formed between the annular limiting block and the conical block.

[0013] As a further technical solution, it also includes: An operating handle is arranged at one end of the flexible rod away from the cleaning member.

[0014] As a further technical solution, the operating handle includes: A connecting block is arranged at one end of the flexible rod away from the cleaning member, wherein the connecting block has a syringe channel, one end of the syringe channel is connected to the inlet end of the cleaning liquid channel, and the other end is an open end, wherein the syringe channel open end is used to install a syringe.

[0015] As a further technical solution, the operating handle further includes: An elastic rod is arranged on the connecting block, and the elastic rod has two.

DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0021] In order to simplify the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0022] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] like Figures 1 to 6 As shown, the present invention provides a detachable and reusable pipe cleaning brush, comprising: a flexible rod 1 and a cleaning member 2, wherein the cleaning member 2 is detachably arranged on the flexible rod 1, and the cleaning member 2 is close to one end of the flexible rod 1.

[0025] In this embodiment, the flexible rod 1 is used as the main structure, which gives the cleaning brush good flexibility. When facing pipes of various shapes and directions, the flexible rod 1 can be bent accordingly according to the curvature of the pipe, so that it can smoothly extend into various positions inside the pipe, greatly expanding the application scope of the cleaning brush, whether it is a straight pipe, a curved pipe or a pipe with complex bends, it can be tried to perform cleaning operations.

[0026] The cleaning member 2 is detachably arranged at one end of the flexible rod 1, and this design has many advantages. From the perspective of the cleaning member 2 itself, as the number of uses increases, the bristles may be worn, damaged, or contaminated with too much dirt that is difficult to remove. At this time, the detachable feature allows the user to easily and quickly remove the old cleaning member 2 and replace it with a new cleaning member 2, so that the cleaning brush can continue to maintain good cleaning ability. Moreover, for pipes with different diameters and different cleaning requirements, cleaning members of different specifications (such as different bristle lengths, densities, etc.) can also be replaced as needed, without replacing the entire cleaning brush, which realizes the reuse of the cleaning brush as a whole, reduces the cost of use, and improves resource utilization.

[0027] Furthermore, the flexible rod 1 is provided with an annular groove 15 , and the cleaning member 2 comprises an elastic sleeve 21 , which is used to be sleeved in the annular groove 15 , and bristles 22 are provided on the outer wall of the elastic sleeve 21 .

[0028] In this embodiment, an annular groove 15 is provided on the flexible rod 1, which provides a specific positioning structure for the installation of the cleaning member 2. The elastic sleeve 21 of the cleaning member 2 can pass through one end of the flexible rod 1 and be sleeved in the annular groove 15. During the process of the cleaning brush entering and exiting the pipeline and performing cleaning actions, this sleeve arrangement can effectively prevent the cleaning member from sliding or shifting along the axial direction of the flexible rod 1 unnecessarily. In this way, the position and force of the bristles 22 on the cleaning member 2 in contact with the inner wall of the pipeline are relatively stable, ensuring that the bristles 22 can continuously and evenly apply wiping, scraping and other effects to the inner wall of the pipeline during the cleaning process, which is conducive to the stable and effective removal of various types of dirt such as dust, stains, scale and so on attached to the inner wall of the pipeline, laying the foundation for achieving high-quality pipeline cleaning.

[0029] Bristles 22 are arranged on the outer wall of the elastic sleeve 21. The bristles 22 are the part that directly contacts the inner wall of the pipe. The material, length, density and other factors of the bristles 22 jointly determine the cleaning effect. Suitable materials of the bristles 22 can play a corresponding cleaning role for dirt of different properties (such as oily dirt, granular dirt, etc.), while appropriate length and density can ensure that the bristles have enough contact area with the inner wall of the pipe, increase the coverage of a single cleaning, and make the cleaning work more thorough.

[0030] Furthermore, the elastic sleeve 21 is rotatably disposed in the annular groove 15 .

[0031] In this embodiment, the elastic sleeve 21 is rotatably arranged in the annular groove 15, which allows the cleaning member 2 to rotate relatively flexibly around the axis of the flexible rod when performing cleaning operations in the pipeline. When the operator pushes or pulls the cleaning brush to move in the pipeline, the cleaning member 2 will not only maintain a fixed angle in contact with the inner wall of the pipeline, but will automatically adjust the angle with the friction with the inner wall and the external force, and the bristles 22 can produce friction and scraping effects on various parts of the inner wall of the pipeline from multiple different directions and in different postures. For example, when cleaning a pipeline with spiral patterns or irregular inner surfaces, the rotating cleaning member can better fit these complex surfaces, avoid cleaning dead corners that are missed due to the fixed angle of the bristles, and clean the inner wall of the pipeline in all directions, significantly enhancing the comprehensiveness and thoroughness of the entire cleaning brush for cleaning different types of pipelines.

[0032] In addition, the elastic sleeve 21 is rotatably arranged, and there is no need to rotate the flexible rod 1 to achieve a more complete cleaning effect brought about by the rotation of the cleaning member 2. While ensuring a better cleaning effect, the operation steps are reduced and the operation is convenient.

[0033] There is a certain gap between the elastic sleeve 21 and the annular groove 15 to ensure that the elastic sleeve 21 can rotate in the annular groove 15 .

[0034] Furthermore, a cleaning liquid channel 11 is provided in the flexible rod 1. One end of the cleaning liquid channel 11 is an outlet end, which is used to introduce cleaning liquid into the vicinity of the cleaning member 2, and the other end is an inlet end.

[0035] In this embodiment, a cleaning liquid channel 11 is constructed in the flexible rod 1, and one end of the channel is the outlet end and close to the cleaning member 2. This design cleverly introduces an auxiliary means of liquid cleaning. In the actual process of cleaning the pipeline, while the bristles 22 physically wipe the inner wall of the pipeline, the cleaning liquid is injected into the vicinity of the cleaning member 2 through the cleaning liquid channel 11, and the cleaning liquid can play a multi-faceted cleaning auxiliary role. For some dry and highly adhesive dirt, the cleaning liquid can dissolve and soften it, making it easier to be wiped off by the bristles 22; for dirt such as dust and fine particles, the flushing effect of the cleaning liquid can flush them away from the inner wall of the pipeline, and they are taken out of the pipeline with the movement of the cleaning brush and the flow of the cleaning liquid. Moreover, the cleaning liquid can also form a thin liquid film on the inner wall of the pipeline, reducing the friction between the bristles and the inner wall, protecting the inner wall of the pipeline from damage caused by excessive scratching by the bristles 22 to a certain extent, and also helping the bristles 22 to move more smoothly in the pipeline, improving the overall cleaning efficiency and cleaning quality, and making the inner wall of the pipeline cleaner and tidier after cleaning.

[0036] Furthermore, it also includes a conical block 3, which is arranged at one end of the flexible rod 1, and the end of the conical block 3 with a smaller diameter is a free end. The conical block 3 is close to the cleaning member 2, and a plurality of cleaning liquid channels 31 are provided on the conical surface of the conical block 3, and the cleaning liquid channels 31 are connected to the outlet end of the cleaning liquid channel 11.

[0037] In this embodiment, the conical block 3 is arranged at one end of the flexible rod 1 and close to the cleaning member 2. Its unique conical structure and the plurality of cleaning liquid channels 31 distributed on the conical surface change the spraying and distribution mode of the cleaning liquid in the pipeline. After the cleaning liquid flows out from the cleaning liquid channel in the flexible rod, it is sprayed out to the surrounding through the cleaning liquid channels 31 on the conical block 3. Due to the shape characteristics of the conical block, the cleaning liquid will be evenly sprinkled on the inner wall of the pipeline near the cleaning member and a larger range in an outward diffusion manner. Compared with spraying the cleaning liquid directly from a single outlet, this method of dispersed spraying through multiple channels allows the cleaning liquid to cover a wider area, avoiding the situation where the local cleaning liquid is too concentrated and the cleaning liquid is insufficient in some parts, making the distribution of the cleaning liquid in the pipeline more uniform and reasonable. In this way, all positions on the inner wall of the pipe can fully enjoy the cleaning effect of the cleaning liquid. No matter it is the top, bottom or side of the pipe, the cleaning liquid can flush and dissolve, and the bristles 22 can better cooperate to wipe the dirt, thereby further improving the cleaning effect of the entire cleaning brush. Especially for pipes with larger diameters or longer lengths, the advantage of this evenly distributed cleaning liquid is more obvious.

[0038] In addition, the conical block 3 can play a guiding role when installing the elastic sleeve 21, thereby facilitating the installation of the elastic sleeve 21.

[0039] Furthermore, a plurality of cleaning liquid channels 31 are evenly distributed along the circumference of the conical block 3 .

[0040] In this embodiment, a plurality of cleaning liquid channels 31 are evenly distributed along the circumference of the conical block 3. This detail design further enhances the uniform spraying of the cleaning liquid. During the cleaning process, each cleaning liquid channel 31 is responsible for spraying the cleaning liquid in the corresponding direction. The evenly distributed channels ensure that the parameters such as the flow rate and pressure of the cleaning liquid sprayed from all directions are basically consistent, so that the cleaning liquid can form a uniform covering layer in the circumferential direction around the conical block and along the axial direction of the pipeline.

[0041] Furthermore, it also includes an annular limit block 4 , which is arranged on the flexible rod 1 , and an annular groove 15 is formed between the annular limit block 4 and the conical block 3 .

[0042] In this embodiment, by providing an annular limit block 4 and forming an annular groove 15 between the annular limit block 4 and the conical block 3, the structure of the annular groove 15 is further stabilized from the structural level. As a part of the groove structure, the annular limit block 4 cooperates and restricts with the conical block, thereby increasing the structural strength and stability of the groove as a whole. Under complex use conditions such as the cleaning brush frequently entering and exiting the pipeline, the cleaning member 2 constantly rotating, and possibly being hit by external forces, this stable annular groove 15 structure can reliably fix the position of the cleaning member 2, prevent the cleaning member 2 from falling off or shifting due to deformation or loosening of the groove, and ensure the firmness and durability of the connection between the cleaning member 2 and the flexible rod 1, thereby ensuring the structural integrity of the entire cleaning brush during long-term and repeated use, maintaining stable cleaning performance, and reducing the occurrence of problems such as cleaning interruptions and poor cleaning effects due to structural instability.

[0043] like Figure 5 As shown, one end of the conical block 3 close to the annular limiting block 4 has a conical groove, and the conical groove can prevent the elastic sleeve 21 from falling off through the conical block 3, making the operation more stable.

[0044] Furthermore, an operating handle 5 is included, and the operating handle 5 is arranged at one end of the flexible rod 1 away from the cleaning member 2 .

[0045] In this embodiment, an operating handle 5 is provided at one end of the flexible rod 1 away from the cleaning member 2, which greatly improves the convenience of the operator in using the cleaning brush. The operating handle 5 provides a comfortable and easy-to-hold position for the operator, so that when inserting the cleaning brush into the pipeline, moving it in the pipeline, and rotating it, the hand can have a stable point of force, and better control the movement trajectory and strength of the cleaning brush. Compared with directly holding the flexible rod, the operating handle 5 conforms to the principle of ergonomics and can reduce hand fatigue, especially when performing pipeline cleaning operations for a long time, this advantage is more obvious.

[0046] Furthermore, the operating handle 5 includes a connecting block 51, which is arranged at one end of the flexible rod 1 away from the cleaning member 2. A syringe channel 52 is provided in the connecting block 51. One end of the syringe channel 52 is connected to the inlet end of the cleaning liquid channel 11, and the other end is an open end. The open end of the syringe channel 52 is used to install the syringe 9.

[0047] In this embodiment, a syringe channel 52 is provided in the connection block 51 of the operating handle 5, and one end thereof is connected to the inlet end of the cleaning liquid channel 11, and the other end is open for installing the syringe 9. This design realizes precise control of the injection of the cleaning liquid.

[0048] Furthermore, the operating handle 5 also includes an elastic rod 53, which is arranged on the connecting block 51. There are two elastic rods 53, and the open end of the syringe channel 52 is located between the two elastic rods 53. The space between the two elastic rods 53 is used to accommodate the syringe 9. The elastic rod 53 has a limiting groove 54, which is used to accommodate the finger grip 91 of the syringe 9. The operating finger ring 55 is arranged on one side of the elastic rod 53.

[0049] In this embodiment, two elastic rods 53 are arranged on the connecting block 51, and the open end of the syringe channel 52 is placed between the two elastic rods 53, forming a space specifically for accommodating the syringe 9. This structure can effectively fix the syringe 9 to prevent it from accidentally detaching due to shaking, external force pulling, etc. during the operation of the cleaning brush, thereby ensuring the continuity and stability of the injection of the cleaning liquid.

[0050] A limiting groove 54 is provided on the elastic rod 53 for accommodating the finger grip 91 of the syringe 9, so that the position of the syringe 9 is more fixed after installation and is less prone to axial or radial displacement. The limiting groove 54 has a depth. When syringes 9 of different lengths are selected, the finger grip 91 can be ensured to be located in the limiting groove 54, thereby adapting to syringes of different lengths.

[0051] The operating finger ring 55 is arranged on one side of the elastic rod 53, providing a convenient and comfortable finger support point for the operator. When injecting cleaning liquid using a syringe, the operator can put his finger through the operating finger ring, and use the finger ring to push the syringe piston more easily and smoothly, accurately control the injection of cleaning liquid, and also reduce the fatigue of the fingers holding the syringe for a long time, so that the operator can perform the cleaning liquid injection operation more attentively and efficiently, thereby ensuring the smooth realization of the overall cleaning function of the cleaning brush.

[0052] The elastic rod 53 is elastic. When the syringe 9 does not need to be installed, the two elastic rods 53 can be bent and brought close to each other and tied together by a rope, so that the operating finger ring 55 can be combined into one, which is more stable and convenient for the operator to operate and use.

[0053] Furthermore, the flexible rod 1 includes a first tube body 12 , a spring sleeve 13 and a second tube body 14 . The first tube body 12 has a cleaning liquid channel 11 . The spring sleeve 13 is sleeved outside the first tube body 12 , and the second tube body 14 is sleeved outside the spring sleeve 13 .

[0054] In this embodiment, the flexible rod 1 is a multi-layer structure consisting of a first tube body 12 (with a cleaning liquid channel), a spring sleeve 13 (sleeved outside the first tube body), and a second tube body 14 (sleeved outside the spring sleeve), each of which plays a unique role and jointly improves the comprehensive performance of the flexible rod.

[0055] The first tube body 12 is a part that carries the cleaning liquid channel. Its structure ensures that the cleaning liquid can be stably and smoothly transmitted inside, providing a basic guarantee for the realization of the auxiliary cleaning function of the cleaning liquid.

[0056] The spring sleeve 13 is sleeved outside the first tube body 12. By utilizing the elastic characteristics of the spring, the flexible rod has a certain flexibility and can be bent to adapt to different pipe shapes. It can also quickly recover to its original shape after being squeezed and bent by external forces, avoiding permanent deformation, thereby improving the elastic recovery ability and durability of the flexible rod. In addition, the spring sleeve can buffer the impact force of the outside world on the internal first tube body to a certain extent, protect the cleaning liquid channel from damage, and ensure that the cleaning liquid can be transported normally.

[0057] The second tube body 14 is sleeved outside the spring sleeve 13, playing the role of outer protection, preventing foreign objects from directly contacting the spring sleeve 13 and the first tube body 12, avoiding scratches, wear and other damages, further enhancing the overall structural strength and wear resistance of the flexible rod 1, and extending the service life of the flexible rod 1, thereby ensuring the reliable use of the entire cleaning brush in different complex environments and maintaining stable cleaning performance. The surface of the second tube body 14 is smooth, which is convenient for cleaning after use and reduces the possibility of bacterial growth.
