[0001] The present invention relates to the technical field of medical devices, and particularly to a pipeline component, an operating handle, and an endoscope. Background Art

[0002] An endoscope is a commonly used medical device, which is an inspection device that can directly enter the natural ducts of the human body and can provide sufficient diagnostic information for doctors to treat diseases. The endoscope is provided with a negative pressure connector, which can connect an external negative pressure source and an instrument tube, and the negative pressure source can provide negative pressure for the instrument tube to realize the suction operation of the endoscope.

[0003] The existing negative pressure connectors have poor installation stability and complicated installation operations. Moreover, the complicated installation operations will also increase the assembly error rate, thereby affecting the assembly yield. Summary of the Invention

[0005] The present application provides a pipeline component for an endoscope. The pipeline component includes a pipeline connector and a negative pressure suction member. The pipeline connector has an output end, and the output end is provided with a first bending portion and a second bending portion, which are bent in directions away from each other. The negative pressure suction member has an input end, and a limiting groove is formed in the input end. The input end includes a connecting portion, and the connecting portion is disposed in the limiting groove. When the input end and the output end are in communication with each other, at least a part of the first bending portion and at least a part of the second bending portion can be embedded in the limiting groove and circumferentially positioned with the connecting portion, so that the input end and the output end are limited and abutted.

[0006] To achieve the above object and other related objects, the present application provides an operating handle including the aforementioned pipeline component.

[0007] To achieve the above object and other related objects, the present application provides an endoscope including the aforementioned operating handle.

[0008] The technical solution adopted by the present invention can achieve the following beneficial effects: The first bending part and the second bending part can be embedded into the limiting groove, and the groove wall of the limiting groove can extrude the first bending part and the second bending part to deform. The two are mutually limited and cooperate with each other, and the sealing of the input end and the output end is realized, avoiding the separation of the output end and the input end from each other, which can improve the structural stability of the pipeline component to ensure the normal operation of the pipeline component. Moreover, at least part of the first bending part and at least part of the second bending part can be circumferentially positioned with the connecting part, which can limit the relative rotation between at least part of the first bending part and at least part of the second bending part and the connecting part, which can avoid the offset, inclination and other situations of the negative pressure attracting part. And, the first bending part and the second bending part have the ability to deform, which can buffer external impacts to ensure the stable connection between the pipeline connector and the negative pressure attracting part. In addition, the assembly connection of the pipeline connector and the negative pressure attracting part is fast. Only by embedding the first bending part and the second bending part into the limiting groove can the assembly be completed. It does not require learning, is easy to operate, and the simple installation operation can also reduce the assembly error rate and improve the assembly yield. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0012] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present invention.

[0013] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0014] In each embodiment of the present application, "proximal end" and "distal end" refer to the relative distances of each component from the user in the usage environment. Among them, the end closer to the user is designated as the "proximal end", and the end farther from the user is designated as the "distal end".

[0015] The installation stability of the negative pressure connector is poor, and the installation operation is cumbersome. The complex installation operation will also lead to an increase in the assembly error rate, thereby affecting the assembly yield. In the prior art, the connection method of the negative pressure connector is simplified, but there are still problems such as poor installation stability, incorrect installation or incomplete installation. For example, after the negative pressure connector is installed on the endoscope, the orientation of the negative pressure connector may deviate from the original preset direction, so that the negative pressure connector cannot be connected to structures such as the collection bottle, resulting in the failure of the negative pressure connector. At this time, it is difficult to disassemble the negative pressure connector, and the reliability of the subsequent structure will also decrease.

[0016] The present application provides a pipeline assembly 100. Please refer to Figure 1 and Figure 2 , the pipeline assembly 100 is used for the endoscope 1. The endoscope 1 can collect image information in the patient's body. For example, a camera module is provided in the insertion part of the endoscope 1, and the camera module can collect or illuminate the situation in the patient's body. At the same time, the insertion part can extend into the patient's body and perform treatment operations, such as aspirating effusion, injecting normal saline, etc. Further, the endoscope 1 is provided with pipelines, including but not limited to the instrument pipeline and the negative pressure suction pipeline in the insertion part. The pipelines can be connected to an external negative pressure source, etc., so that the pipelines can inject or aspirate media, etc.

[0017] In the embodiment of the present application, please refer to Figure 3 , the pipeline assembly 100 may include a pipeline connector 110 and a negative pressure suction member 120, and the pipeline connector 110 and the negative pressure suction member 120 are connected. It can be understood that the pipeline connector 110 can connect the pipelines inside the endoscope 1, and the pipelines can extend to the distal end of the insertion part for suction. The negative pressure suction member 120 can extend outside the endoscope 1 and be connected to the negative pressure source. The pipeline connector 110 and the negative pressure suction member 120 are connected, and the negative pressure effect of the negative pressure source can act on the insertion part, which can provide a flow power for the medium in the pipeline. In addition, the endoscope 1 further includes a sampling structure such as a sampling bottle, and the negative pressure suction member 120 can also be connected to the sampling bottle. Driven by the negative pressure, the medium can flow into the sampling bottle to complete the sampling operation. At the same time, the sampling bottle is located between the negative pressure suction member 120 and the negative pressure source, and the negative pressure effect of the negative pressure source can act on the negative pressure suction member 120, and the medium will be left in the sampling bottle to avoid the medium damaging the negative pressure source.

[0018] Please refer to Figure 4, the pipeline connector 110 has an output end 111, which can be a hollow cylindrical structure, a rectangular structure, etc., and is not limited here. The output end 111 can be connected to the pipeline, and the medium in the pipeline can also flow to the output end 111, and the medium can flow through the output end 111 to the negative pressure suction member 120. The output end 111 is provided with a first bending portion 1111 and a second bending portion 1112, and the first bending portion 1111 and the second bending portion 1112 are bent in directions away from each other. Exemplarily, the first bending portion 1111 and the second bending portion 1112 can be sheet-like structures, and the end of the first bending portion 1111 can be bent toward the side away from the second bending portion 1112, and the end of the second bending portion 1112 can be bent toward the side away from the first bending portion 1111. Of course, the first bending portion 1111 and the second bending portion 1112 can also be other structures, such as a cube, etc., and are not limited.

[0019] Part of the existing negative pressure suction member is exposed for connecting a sampling bottle, etc. However, during use, the exposed sampling bottle is prone to collide with the outside world. The existing sampling bottle is cemented to the negative pressure suction member, and the collision force generated by the accidental collision of the sampling bottle is conducted and attenuated at the cemented joint between the two, which is likely to cause the cemented joint to crack and affect the connection tightness of the internal pipeline of the endoscope. In the present application, please refer to Figure 3 and Figure 5 , the negative pressure suction member 120 has an input end 121, a limiting groove 1214 is opened in the input end 121, and the input end 121 includes a connecting portion 1211, and the connecting portion 1211 is arranged in the limiting groove 1214. While the input end 121 and the output end 111 are in communication with each other, at least part of the first bending portion 1111 and at least part of the second bending portion 1112 can be embedded in the limiting groove 1214, so that the groove wall of the limiting groove 1214 can squeeze the first bending portion 1111 and the second bending portion 1112 to deform, and the two are mutually limited and matched, and the sealing setting of the input end 121 and the output end 111 is realized. At this time, as Figure 6 shown, Figure 6The deformed first bending portion 1111 and second bending portion 1112 are shown. Affected by the groove walls of the limiting groove 1214, the first bending portion 1111 and the second bending portion 1112 bend towards each other and deform. The first bending portion 1111 and the second bending portion 1112 can apply forces in different directions to the groove walls, and the forces can generate frictional forces with the groove walls to prevent the output end 111 and the input end 121 from separating from each other, which can improve the structural stability of the pipeline assembly 100 to ensure the normal operation of the pipeline assembly 100. Further, due to the deformation ability of the first bending portion 1111 and the second bending portion 1112, the first bending portion 1111 and the second bending portion 1112 can elastically abut against the groove walls forming the limiting groove 1214, and the first bending portion 1111 and the second bending portion 1112 can also elastically abut against the connecting portion 1211 to elastically seal the input end 121 and the output end 111. When the sampling bottle is bumped, impacted, etc., the external impact force will be transmitted to the connection between the input end 121 and the output end 111, and at least one of the first bending portion 1111, the second bending portion 1112, the connecting portion 1211, and the groove walls forming the limiting groove 1214 can undergo small deformations to buffer the impact force to prevent the endoscope 1 from being structurally damaged, etc., and improve the anti-collision ability and structural stability of the endoscope 1. During this period, the elastic setting can always ensure the sealed setting of the connection between the input end 121 and the output end 111. For example, when the first bending portion 1111 undergoes small deformations, the connecting portion 1211 and the groove walls forming the limiting groove 1214 can also correspondingly undergo elastic deformations to keep them always closely connected. And they can quickly return to their original states subsequently, always ensuring the sealing performance of the pipeline assembly 100 and improving the use reliability.

[0020] Meanwhile, at least part of the first bending portion 1111 and at least part of the second bending portion 1112 can be circumferentially positioned with the connecting portion 1211 to limit and stop the input end 121 and the output end 111. Exemplarily, the pipeline connector 110 is installed inside the endoscope 1, and part of the negative pressure suction member 120 can extend out of the endoscope 1. By the way that at least part of the first bending portion 1111 and at least part of the second bending portion 1112 can be circumferentially positioned with the connecting portion 1211, it can ensure that the orientation of the negative pressure suction member 120 after assembly conforms to the preset direction.

[0021] It is understandable that the pipeline connector 110 and part of the negative pressure suction member 120 are arranged inside the operation handle 200 of the endoscope 1. The internal space of the operation handle 200 is limited, and the installation and fixing positions and spaces for the pipeline connector 110 and the negative pressure suction member 120 have been reserved during the design. For the convenience of production, generally, the input end 121 and the output end 111 are first connected and fixed, and then installed and fixed inside the operation handle 200. If the relative positions of the connection and fixation between the input end 121 and the output end 111 are misaligned, it will cause the inability to correctly install and fix onto the operation handle 200, resulting in the need for secondary adjustment of the input end 121 and the output end 111, increasing the difficulty of production assembly and reducing the production assembly efficiency. In this application, by means of the circumferential positioning of at least part of the first bending portion 1111 and at least part of the second bending portion 1112 with the connecting portion 1211, the connecting portion 1211 can achieve pre-positioning, avoiding deviation in the connection positions of the output end 111 and the input end 121, and ensuring that the orientation of the negative pressure suction member 120 after assembly conforms to the preset direction. Its installation method is simple and easy to operate, without the need for learning. Simple installation operations can also reduce the assembly error rate and improve the assembly yield rate.

[0022] In a more specific implementation manner, please refer to Figure 6 , the input end 121 may further include a sealing portion 1212 and a coupling portion 1213. Among them, in some cases, both the sealing portion 1212 and the coupling portion 1213 may be configured as arc-shaped structures. Of course, in other cases, the sealing portion 1212 and the coupling portion 1213 may also be provided with other structures such as annular structures, which are not limited herein. Further, the sealing portion 1212 and the coupling portion 1213 may be provided on the surface of the pipeline connector 110 to form the input end 121. The sealing portion 1212 can be in mutual abutment with the first bending portion 1111 and the second bending portion 1112, and the coupling portion 1213 can be connected to an external negative pressure source, which can achieve the connection between the pipeline connector 110 and the negative pressure source.

[0023] Please refer to Figure 7, the sealing portion 1212 and the coupling portion 1213 are spaced apart to form a limiting groove 1214. In other words, the limiting groove 1214 can be formed between the sealing portion 1212 and the coupling portion 1213. For example, the sealing portion 1212 can be arranged to surround the coupling portion 1213, which can make the limiting groove 1214 surround the coupling portion 1213. The connecting portion 1211 is connected between the sealing portion 1212 and the coupling portion 1213. Further, the connecting portion 1211 can be arranged in the limiting groove 1214. The connecting portion 1211 can improve the connection stability between the sealing portion 1212 and the coupling portion 1213 and avoid situations such as excessive deformation. An insertion space 1113 is formed between the first bending portion 1111 and the second bending portion 1112. The insertion space 1113 can communicate with the pipeline of the insertion portion of the endoscope 1. The coupling portion 1213 can be inserted into the insertion space 1113.

[0024] In the embodiment of the present application, please refer to Figure 4 and Figure 7 , a coupling groove 112 is formed in the output end 111. The coupling groove 112 can be a through groove or the like, and no specific limitation is made. The connecting portion 1211 and the coupling groove 112 are correspondingly arranged. The structure and size of the coupling groove 112 can be correspondingly arranged with the connecting portion 1211. While the input end 121 and the output end 111 are in communication with each other, the connecting portion 1211 is embedded in the coupling groove 112. After the connecting portion 1211 is embedded in the coupling groove 112, due to the tight fit between the connecting portion 1211 and the coupling groove 112, the connecting portion 1211 can effectively fill the space of the coupling groove 112 and prevent gases, liquids or other impurities in the external environment from entering the position of the connecting portion 1211, thereby achieving the effect of sealing the coupling groove 112. At the same time, it also avoids the leakage of internal media.

[0025] In addition, please refer to Figure 7 , the setting of the connecting portion 1211 embedded in the coupling groove 112 not only has a sealing effect but also has a limiting and anti-rotation effect. After the connecting portion 1211 is embedded in the coupling groove 112, the connecting portion 1211 abuts against the groove wall forming the coupling groove 112. The groove wall can limit the rotation and movement of the connecting portion 1211 in the coupling groove 112, ensuring that the output end 111 and the input end 121 maintain a relatively fixed positional relationship in the connected state and preventing problems such as connection loosening and sealing failure caused by rotation or displacement, further improving the connection stability and reliability.

[0026] Furthermore, please refer to Figure 8, the engaging groove 112 includes a first sub-engaging groove 1121 and a second sub-engaging groove 1122. The first sub-engaging groove 1121 and the second sub-engaging groove 1122 are formed at the output end 111 to divide the output end 111 into a first bending portion 1111 and a second bending portion 1112. Among them, the output end 111 can be prepared by integral injection molding or the like, that is, the first sub-engaging groove 1121, the second sub-engaging groove 1122, the first bending portion 1111, and the second bending portion 1112 are integrally formed. This can improve the connection effect of the pipeline connector 110 and also realize the limiting and abutting functions of the first bending portion 1111 and the second bending portion 1112.

[0027] The connecting portion 1211 may further include a first sub-connecting portion 1215 and a second sub-connecting portion 1216. The first sub-connecting portion 1215 and the second sub-connecting portion 1216 are located in the limiting groove 1214 and are distributed along the circumferential direction of the engaging portion 1213. Among them, the first sub-connecting portion 1215 and the second sub-connecting portion 1216 may be evenly or unevenly distributed along the circumferential direction of the engaging portion 1213. In other words, the first sub-connecting portion 1215 and the second sub-connecting portion 1216 may be distributed on the same diameter of the engaging portion 1213. Of course, the two of them may also be distributed on two different diameters of the engaging portion 1213, and there is no limitation.

[0028] When the engaging portion 1213 can be inserted into the insertion space 1113, the first sub-connecting portion 1215 can be embedded and seal the first sub-engaging groove 1121, and the second sub-connecting portion 1216 can be embedded and seal the second sub-engaging groove 1122. Through at least part of the first bending portion 1111 and at least part of the second bending portion 1112, they can be mutually limited and connected with the connecting portion 1211, and the limiting and abutting between the input end 121 and the output end 111 are realized, avoiding situations such as deflection and tilting caused by external forces. At the same time, during the process of the first sub-connecting portion 1215 and the second sub-connecting portion 1216 being embedded into the corresponding first sub-engaging groove 1121 and the second sub-engaging groove 1122, a sealing function is realized, preventing fluid leakage or intrusion of external impurities, and ensuring the sealing performance and reliability of the entire connection structure. In addition, the first sub-connecting portion 1215 and the second sub-connecting portion 1216 can be evenly stressed, avoiding unilateral stress on the input end 121, which can avoid stress concentration and damage to the structural stability and improve the structural stability.

[0029] In the embodiment of the present application, at least one of the first sub-connecting portion 1215 and the second sub-connecting portion 1216 is provided with a groove 1217, and at least one of the first sub-engaging groove 1121 and the second sub-engaging groove 1122 is correspondingly provided with a protrusion 115, and the groove 1217 and the protrusion 115 cooperate with each other. As Figure 4 shown, a protrusion 115 is provided on the cavity wall forming the first sub-engaging groove 1121 and / or the second sub-engaging groove 1122. AsFigure 9 and Figure 10 As shown in Figure 10 , the wall surface of the first sub-connection part 1215 and / or the second sub-connection part 1216 is provided with a groove 1217. The shape, size, depth and position of the groove 1217 are correspondingly set with the bump 115. For example, the groove 1217 is a circular groove, and the bump 115 can be correspondingly configured as circular, which is not limited herein.

[0030] While the input end 121 and the output end 111 are in communication with each other, the bump 115 can be embedded in the groove 1217. During the assembly process, when the first sub-connection part 1215 and the second sub-connection part 1216 of the connection part 1211 are inserted into the first sub-coupling groove 1121 and the second sub-coupling groove 1122 of the output end 111, before the groove 1217 and the bump 115 come into contact and cooperate, the bump 115 can be in contact with at least one of the groove walls of the first sub-coupling groove 1121 and the second sub-coupling groove 1122 and generate frictional resistance. As the connection part 1211 continues to be inserted, the bump 115 gradually approaches the groove 1217 until the bump 115 is completely embedded in the groove 1217. At this time, due to the shape adaptation of the bump 115 and the groove 1217, the two form a tight fitting structure, and the frictional resistance is greatly reduced, resulting in a sharp drop in the resistance during the insertion process. This cooperation mode of the groove 1217 and the bump 115 makes the connection process between the input end 121 and the output end 111 show an obvious sense of paragraph. This setting not only facilitates the assembler to perceive the connection process and judge whether the connection is installed in place, but also can rely on the mutual engagement of the two after the bump 115 is embedded in the groove 1217 to achieve the positioning and anti-loosening functions, enhancing the stability and reliability of the connection between the input end 121 and the output end 111.

[0031] In the embodiment of the present application, please refer to Figure 7, the widths or lengths of the first sub-connection part 1215 and the second sub-connection part 1216 are different. At the same time, the first sub-connection part 1215 is correspondingly arranged with the first sub-coupling groove 1121, and the second sub-connection part 1216 is correspondingly arranged with the first sub-connection part 1215 and the first sub-coupling groove 1121. Furthermore, the groove widths or groove depths of the first sub-coupling groove 1121 and the second sub-coupling groove 1122 are different. Due to the different specifications of the two sub-connection parts 1211, when performing the connection operation, if the first sub-connection part 1215 is aligned with the second sub-coupling groove 1122, or the second sub-connection part 1216 is aligned with the first sub-coupling groove 1121, there will be an obstruction due to size mismatch. Only the first sub-connection part 1215 can be inserted into the first sub-coupling groove 1121, and the second sub-connection part 1216 can be inserted into the second sub-coupling groove 1122, which helps to avoid installation misalignment caused by incorrect insertion directions. This design effectively avoids connection errors caused by misoperations during the assembly process, reduces the operation difficulty, is easier to start with and has a lower learning cost, improves the reliability and assembly efficiency of the connection structure, and ensures the stability and functionality of the connection during the operation of the device or system.

[0032] Of course, the first sub-connection part 1215 and the second sub-connection part 1216 can also be configured in different shapes to eliminate the risk of incorrect insertion and other situations. For example, the cross-sections of the first sub-connection part 1215 and the first sub-coupling groove 1121 are configured as rectangles, and the cross-sections of the first sub-connection part 1215 and the first sub-coupling groove 1121 are configured as trapezoids. There is no limitation here.

[0033] In the embodiment of the present application, please refer to Figure 5 and Figure 7 , the sealing part 1212 can include a first sub-sealing part 1218 and a second sub-sealing part 1219, and the first sub-sealing part 1218 and the second sub-sealing part 1219 are arranged at intervals along the circumferential direction of the joint part 1213. Further, the first sub-sealing part 1218 and the second sub-sealing part 1219 can be arranged at equal intervals along the circumferential direction of the joint part 1213, that is, the first sub-sealing part 1218 and the second sub-sealing part 1219 are on the same diameter of the joint part 1213. Or, the first sub-sealing part 1218 and the second sub-sealing part 1219 can be arranged at different intervals along the circumferential direction of the joint part 1213. There is an operation gap 1221 between the first sub-sealing part 1218 and the second sub-sealing part 1219, and the operation gap 1221 communicates with the limit groove 1214.

[0034] At least one of the first bending portion 1111 and the second bending portion 1112 is correspondingly arranged with the operation gap 1221. While the first bending portion 1111 and the second bending portion 1112 are inserted into the limit groove 1214, the operation gap 1221 can expose at least one of the first bending portion 1111 and the second bending portion 1112. This can provide an observation space for the assembler. During the assembly process, by directly observing the position and state of the exposed part, the assembler can accurately judge whether the first bending portion 1111 and the second bending portion 1112 are inserted in place, avoiding incomplete connection and ensuring the accuracy and integrity of the connection. In addition, from the perspective of operation convenience, when performing the installation operation, the space formed by the operation gap 1221 provides an operation area for the finger part of the installer. Specifically, the installer can insert the finger part into the operation gap 1221, pinch the first bending portion 1111 and the second bending portion 1112, and apply an external force to make the first bending portion 1111 and the second bending portion 1112 move towards each other, so that the first bending portion 1111 and the second bending portion 1112 can adapt to the structure of the limit groove 1214, so as to more easily insert them into the limit groove 1214. At the same time, during the insertion process, the finger part can also continuously push and abut against the first bending portion 1111 or the second bending portion 1112 through the operation gap 1221. Compared with the structure without the operation gap 1221, this setting is beneficial to effectively reduce the assembly resistance, improve the assembly efficiency and operation convenience.

[0035] In addition, in some other cases, the sealing portion 1212 can be configured as an annular structure, and the joint portion 1213 is arranged inside the sealing portion 1212 to form the limit groove 1214. When the first bending portion 1111 and the second bending portion 1112 are inserted into the limit groove 1214, they can still abut and limit each other with the annular sealing portion 1212 to achieve a stable connection between the output end 111 and the input end 121, and no limitation is made here.

[0036] In one embodiment, please refer to Figure 4, a sealing groove 1222 is provided in the first sub-sealing portion 1218 and / or the second sub-sealing portion 1219. The sealing groove 1222 communicates with the limiting groove 1214. A sealing rib 1123 is provided on the output end 111. The sealing rib 1123 is arranged around the first sub-coupling groove 1121 and / or the second sub-coupling groove 1122. Further, the sealing rib 1123 is arranged along the edges of the corresponding first sub-coupling groove 1121 and the second sub-coupling groove 1122. While at least part of the first bending portion 1111 and at least part of the second bending portion 1112 can be embedded in the limiting groove 1214, the sealing rib 1123 can be embedded in the sealing groove 1222. The sealing rib 1123 can be tightly connected to the sealing groove 1222, which can prevent the medium from leaking out from the joint between the output end 111 and the input end 121 and improve the sealing degree between the two. In addition, the sealing rib 1123 can be elastic, that is, the sealing rib 1123 can be configured as an elastic member, and the sealing rib 1123 can be elastically connected to the groove wall forming the sealing groove 1222 to improve the sealing degree between the two.

[0037] The side surface of the first sub-sealing portion 1218 and / or the second sub-sealing portion 1219 is a guiding arc surface 1224. The cross-sectional shape of the guiding arc surface 1224 can be circular arc or non-circular arc, etc. The guiding arc surface 1224 can guide the first bending portion 1111 and the second bending portion 1112 to be embedded in the limiting groove 1214 along the direction of approaching each other. The guiding arc surface 1224 has a guiding effect. It can guide the first bending portion 1111 and the second bending portion 1112 into the limiting groove 1214, which can enable the first bending portion 1111 and the second bending portion 1112 to enter the limiting groove 1214 through the side surfaces of the first sub-sealing portion 1218 and the second sub-sealing portion 1219, which is beneficial to improving the success rate of inserting the first bending portion 1111 and the second bending portion 1112 into the limiting groove 1214 and reducing the installation difficulty.

[0038] In addition, a fastening groove is provided in the groove wall forming the limiting groove 1214, and fastening portions are arranged on the side surfaces of the first bending portion 1111 and the second bending portion 1112. The fastening portions can be connected to the fastening groove to prevent the first bending portion 1111 and the second bending portion 1112 from recovering to their original state and generating elastic force and disengaging from the limiting groove 1214.

[0039] In the embodiment of the present application, please refer to Figure 4, both the first bending portion 1111 and the second bending portion 1112 may include a first section 1114 and a second section 1115. For the convenience of understanding, the following content will take the first bending portion 1111 including the first section 1114 and the second section 1115 as an example for description. The first section 1114 extends along the central axis of the output end 111. One end of the second section 1115 is connected to the first section 1114, and the other end is bent away from the central axis of the output end 111. The first sub-coupling groove 1121 and the second sub-coupling groove 1122 are formed in the second section 1115 and not in the first section 1114, and the structural strength of the first section 1114 is greater. The first section 1114 can be inserted into the limit groove 1214 and abuts against the sealing portion 1212. The first section 1114 can effectively increase the anti-bending moment ability of the pipeline connector, avoid the leakage of the medium or the failure of the structure due to the too low structural strength of the pipeline connector, and improve the structural reliability of the pipeline assembly 100.

[0040] In the embodiment of the present application, please refer to Figure 5 and Figure 8 , the pipeline connector 110 is provided with a conduction portion 113. The conduction portion 113 may be a hollow structure. The conduction portion 113 can be correspondingly arranged with the coupling portion 1213. For example, if the coupling portion 1213 is a hollow cylindrical structure, the conduction portion 113 can also be correspondingly configured as a hollow cylindrical structure of the same size. The conduction portion 113 communicates with the insertion space 1113. When the coupling portion 1213 is inserted into the insertion space 1113, the coupling portion 1213 can abut against the conduction portion 113, which can stably connect the coupling portion 1213 and the conduction portion 113 to each other. Of course, at least part of the first bending portion 1111 and at least part of the second bending portion 1112 can be limited and abutted against the connecting portion 1211, which can also make the output end 111 and the input end 121 abut tightly against each other, so that a pre-tightening force can be generated between the coupling portion 1213 and the conduction portion 113, so as to improve the sealing connection effect between the pipeline connector 110 and the negative pressure suction member 120.

[0041] In one implementation manner, please refer to Figure 5, a first abutting portion 114 is provided on the outer surface of the first section 1114. The first abutting portion 114 can be configured as a bump structure. Further, the first abutting portion 114 can be configured as an annular bump structure and is arranged around the outer surface of the first section 1114. The first abutting portion 114 can be in limit abutment with the sealing portion 1212. When the first abutting portion 114 and the sealing portion 1212 are in abutment, the joint portion 1213 and the conduction portion 113 are in abutment and communicate with each other. During the assembly process, as the joint portion 1213 and the conduction portion 113 gradually approach and abut, the first abutting portion 114 starts to abut against the sealing portion 1212. Furthermore, the relative position and contact state between the first abutting portion 114 and the sealing portion 1212 directly reflect the connection situation or process of the joint portion 1213 and the conduction portion 113. That is, when the first abutting portion 114 and the sealing portion 1212 are in abutment, the joint portion 1213 and the conduction portion 113 are in abutment and communicate with each other. At least part of the first abutting portion 114 and the sealing portion 1212 are exposed to the view of the installer, and the installer can clearly observe the connection situation of the first abutting portion 114 and the sealing portion 1212, improving the assembly visualization degree of the pipeline assembly 100 and ensuring that the assembly of the pipeline assembly 100 can be in place.

[0042] In another embodiment, please continue to refer to Figure 5 , the negative pressure suction member 120 is provided with a second abutting portion 1223. The second abutting portion 1223 can be integrally formed with the negative pressure suction member 120, such as integrally injection molded, etc., without limitation. The second abutting portion 1223 connects the sealing portion 1212 and the joint portion 1213 and forms the bottom of the limiting groove 1214. The second abutting portion 1223 can be in limit abutment with the first bending portion 1111 and / or the second bending portion 1112. When the second abutting portion 1223 and the sealing portion 1212 are in abutment, the joint portion 1213 and the conduction portion 113 are in abutment and communicate with each other. During the assembly process, as the joint portion 1213 and the conduction portion 113 gradually approach and abut, the second abutting portion 1223 starts to abut against the first bending portion 1111 and / or the second bending portion 1112. Furthermore, the relative position and contact state between the second abutting portion 1223 and the first bending portion 1111 and / or the second bending portion 1112 directly reflect the connection situation or process of the joint portion 1213 and the conduction portion 113. At least part of the second abutting portion 1223 and the first bending portion 1111 and / or the second bending portion 1112 are exposed to the view of the installer, and the installer can clearly observe the connection situation of the second abutting portion 1223 and the first bending portion 1111 and / or the second bending portion 1112, improving the assembly visualization degree of the pipeline assembly 100 and ensuring that the assembly of the pipeline assembly 100 can be in place.

[0043] Of course, the first abutting portion 114 and the second abutting portion 1223 can be provided simultaneously, which can show the connection between the negative pressure suction member 120 and the pipe connector in multiple directions, and can obtain the installation condition more clearly and accurately. Details are not described herein in excess.
