Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a pipeline fixing structure of a flushing and suction device and a flushing and suction device. Background Art

[0002] The flushing and suction device is an important tool used in laparoscopic surgery and open surgery, used to provide flushing fluid to the surgical site to clean the vision of the bleeding site, and to suck blood, other liquids and tissue debris from the surgical site by means of vacuum suction.

[0003] The flushing and suction device mainly uses a single-lumen tube to perform flushing and suction through a common cavity. The sharing of the same inner cavity for suction and flushing also causes the "dirty" liquid just sucked back to flow back into the patient's body, which makes it more difficult to explore the bleeding site.

[0004] For this reason, the prior art proposes to adopt independent flushing pipelines and suction pipelines. The flushing pipeline is independently controlled to be conducted through a flushing switch, and can cooperate with a flushing elastic piece to control the flushing pipeline to remain in a disconnected state; the suction pipeline is independently controlled to be conducted through a suction switch, and can cooperate with a suction elastic piece to control the suction pipeline to remain in a disconnected state.

[0005] However, it is found in actual application that the flushing pipeline and the suction pipeline have a shaking problem, which will affect the independent control of the flushing pipeline and the suction pipeline. When the flushing switch controls the flushing pipeline to be conducted, it is easy for the suction pipeline to shake and cause the suction pipeline to be opened accordingly. Similarly, when the suction switch controls the suction pipeline to be conducted, it is easy for the flushing pipeline to shake and cause the flushing pipeline to be opened.

[0006] Although a pipeline fixing structure is proposed to be arranged in the flushing and suction housing to fix the flushing pipeline and the suction pipeline to the housing, the existing pipeline fixing structure is relatively complex, occupies a large space, and the pipeline is extremely prone to axial pull-off problems. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a pipeline fixing structure of a flushing and suction device and a flushing and suction device, which has a simple structure, occupies a small space, and can increase the axial pulling force of the pipeline, effectively preventing the pipeline from axially pulling off.

[0008] To achieve this purpose, the utility model adopts the following technical solutions:

[0009] The pipeline fixing structure of the flushing and suction device includes two pipeline joints arranged side by side along the first direction, two first limiting members, and two second limiting members arranged in one-to-one correspondence with the two pipeline joints, and the second limiting members are used for connecting the flushing and suction housing of the flushing and suction device;

[0010] Any one of the pipe joints is fixed to the two first limit members, and the two second limit members are axially clamped between the two first limit members along the pipe joint;

[0011] The second limit member includes a first limit portion and two second limit portions spaced along the second direction. The pipe joint is axially clamped between the two first limit portions of the corresponding second limit member, and the two pipe joints are axially clamped between the first limit portions of the two second limit members along the first direction; the first direction, the second direction and the axial direction of the pipe joint are perpendicular to each other in pairs.

[0012] As an implementable solution of the pipe fixing structure of the above flushing and suction device, a clamping groove is provided on any one of the second limit members, and the opening of the clamping groove faces the other second limit member;

[0013] The bottom wall of the clamping groove forms the first limit portion, and each of the two side walls of the clamping groove oppositely arranged along the second direction forms a second limit portion.

[0014] As an implementable solution of the pipe fixing structure of the above flushing and suction device, the two first limit members and the two pipe joints are integrally formed into a structural member.

[0015] To achieve the above object, the present invention also provides a flushing and suction device, including two pipes and the pipe fixing structure of the above flushing and suction device in any implementable solution. The two pipes are arranged in one-to-one correspondence with the two pipe joints, and each pipe includes two sub-pipes, and the two sub-pipes are respectively connected to both ends of the corresponding pipe joint.

[0016] As an implementable solution of the above flushing and suction device, the sub-pipe is inserted into the corresponding pipe joint in an interference fit manner.

[0017] As an implementable solution of the above flushing and suction device, a sealing glue is provided between the sub-pipe and the corresponding pipe joint.

[0018] As an implementable solution of the above flushing and suction device, the flushing and suction device further includes a flushing and suction housing, the flushing and suction housing includes two half-shells distributed along the first direction, and the two half-shells are connected to enclose an installation cavity, and the pipe fixing structure is arranged in the installation cavity; the two second limit members are fixedly arranged on the inner walls of the corresponding half-shells in one-to-one correspondence.

[0019] As an implementable solution of the above flushing and suction device, a reinforcing rib is connected between the half-shell and the second limit member.

[0020] As an implementable embodiment of the above flushing and suction device, the second limiting member is provided with the reinforcing ribs at both ends in the second direction.

[0021] As an implementable embodiment of the above flushing and suction device, the second limiting member, the reinforcing ribs and the corresponding half shell are integrally formed into a structural member.

[0022] Advantages of the present utility model: For the pipeline fixing structure and the flushing and suction device of the flushing and suction device provided by the present utility model, the second limiting member is axially clamped between two first limiting members along the pipeline to limit the pipeline joint along the axial direction of the pipeline; two pipeline joints are clamped between the first limiting parts of two second limiting members along the first direction to limit the pipeline joint along the first direction; the pipeline joint is clamped between two first limiting parts of the corresponding second limiting member along the second direction to limit the pipeline joint along the second direction.

[0023] The flushing pipeline and the suction pipeline share a pipeline fixing structure. The pipeline fixing structure is relatively simple, with fewer components, and there is no need to use connection structures such as fasteners. As long as the pipeline joint is limited from the first direction, the second direction and the axial direction of the pipeline, the pipeline connected to the pipeline joint can be limited. The installation method is simple, the disassembly is convenient and fast, the structure is simple, and the occupied space is small.

[0024] Clamping the second limiting member axially between two first limiting members along the pipeline can greatly increase the axial pulling force of the pipeline, thus effectively preventing the phenomenon of axial pulling and dragging of the pipeline. Description of the Drawings

It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the convenience of description, only the parts related to the present utility model are shown in the drawings, rather than all the structures

[0049] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings

[0050] In the embodiments of the present utility model Figures 1 to 14The X - direction is the first direction, the Y - direction is the second direction, and the Z - direction is the axial direction of the pipe joint. The X - direction, Y - direction, and Z - direction are perpendicular to each other pairwise. Among them, both the X - direction and the Y - direction are the radial directions of the pipe.

[0051] Embodiment 1

[0052] An embodiment of the present utility model provides a flushing and suction device, which can realize independent control of the flushing pipe and the suction pipe respectively, and has high control accuracy.

[0053] As Figures 1 to 3 shown, the flushing and suction device includes two pipes 1, a partition structure 2, and a on - off control component 3. Among them, the two pipes 1 are arranged side by side along the first direction. The partition structure 2 includes a partition plate 21, and the partition plate 21 is located between the two pipes 1. The on - off control component 3 corresponds to the pipe 1 one by one and is on the same side of the partition plate 21 as the corresponding pipe 1. The on - off control component 3 is used to control the on - off of the corresponding pipe 1.

[0054] For the convenience of description, the two pipes 1 are respectively denoted as a flushing pipe 1b and a suction pipe 1a. The flushing pipe 1b and the suction pipe 1a are arranged side by side along the first direction. The partition plate 21 is arranged along the first direction between the two flushing pipes 1b and the suction pipe 1a. The partition plate 21 is used to separate the flushing pipe 1b and the suction pipe 1a, and the partition plate 21 is also used to separate the on - off control component 3 for controlling the on - off of the flushing pipe 1b and the on - off control component 3 for controlling the on - off of the suction pipe 1a, so that when any on - off control component 3 independently controls the on - off of the corresponding pipe 1, this on - off control component 3 will not affect the on - off of the other pipe 1, which can greatly improve the accuracy of the on - off control of the pipe 1.

[0055] Furthermore, as Figures 1 to 3 shown, the partition structure 2 further includes support bases 22 corresponding to the pipes 1 one by one and connected to the partition plate 21 for supporting the corresponding pipes 1. The on - off control component 3 includes an on - off switch 31 and an elastic reset member 32. Among them, one end of the on - off switch 31 has an operation part 311, and the other end has a pressing part 312. The on - off switch 31 can rotate around a preset axis. The preset axis is located between the operation part 311 and the pressing part 312 along the extension direction of the on - off switch 31, so that when the operation part 311 is pressed, the pressing part 312 is lifted off the support base 22 to conduct the pipe 1. The elastic reset member 32 is used to make the pressing part 312 have a movement trend of pressing towards the support base 22 to cut off the pipe 1.

[0056] When the flushing and suction device is not in use, the elastic reset member 32 applies a force to the pressing part 312, and the pressing part 312 presses towards the support base 22 to cut off the pipe 1.

[0057] By pressing the operating part 311, the on-off switch 31 will rotate around the preset axis, causing the squeezing part 312 to overcome the resistance of the elastic return member 32 and lift off the support base 22, so that the pipeline 1 is conductive; during this process, the elastic return member 32 accumulates elastic return force. When the external force applied to the operating part 311 is removed, the squeezing part 312 is reset under the action of the elastic return member 32 to cut off the pipeline 1.

[0058] Exemplarily, both the flushing pipe 1b and the suction pipe 1a are hoses, so that the squeezing portion 312 squeezes the pipe 1 to deform and cut it off, and when the squeezing portion 312 is lifted off the support base 22, the pipe 1 automatically recovers its deformation and becomes conductive.

[0059] In this embodiment, the irrigation and suction device further includes an irrigation and suction housing, within which is disposed a rotating shaft 51. Both on-off switches 31 are rotatably mounted on the rotating shaft 51, with the central axis of the rotating shaft 51 being the aforementioned predetermined axis. Both ends of the rotating shaft 51 are connected to the irrigation and suction housing, supporting the two on-off switches 31. The two on-off switches 31 share a common rotating shaft 51, simplifying the structure of the irrigation and suction device.

[0060] For example, two rotating protrusions are provided on the flushing and suction housing, and both ends of the rotating shaft 51 are rotatably inserted into the two rotating protrusions respectively, so as to improve the rotation smoothness of the on-off switch 31.

[0061] In this embodiment, if Figure 1 As shown, the on-off switch 31 is provided with a guide hole 313, which is an arc-shaped hole centered on a predetermined axis. The flushing and suction housing is provided with a guide member 52. The axial ends of the guide member 52 extend through the two guide holes 313 and are connected to the flushing and suction housing. The guide member 52 and the guide hole 313 slide circumferentially about the predetermined axis. During rotation of the on-off switch 31 about the predetermined axis, the guide member 52 and the guide hole 313 slide circumferentially about the predetermined axis to guide the rotation of the on-off switch 31.

[0062] In this embodiment, the elastic return member 32 is a torsion spring 32b, and the partition structure 2 also includes a return mounting portion 25 and a return limiting portion 27, both of which are connected to the partition plate 21 and correspond one-to-one to the pipeline 1. The return mounting portion 25 is passed through the torsion spring 32b, and one end of the torsion spring 32b is crimped to the side of the extrusion portion 312 facing away from the pipeline 1; the return limiting portion 27 is crimped to the other end of the torsion spring 32b.

[0063] It should be noted that the two on-off control components 3 may use two independent torsion springs 32b, or may use a double torsion spring. For example, the two on-off control components 3 use a double torsion spring.

[0064] Specifically, the two reset mounting parts 25 are integrated into a reset mounting post. The reset mounting post penetrates through the partition plate 21 rotatably about its own axis in the first direction, and both ends of the reset mounting post are rotatably connected to the flushing and suction housing about its own axis.

[0065] Furthermore, as Figures 1 to 3 shown, the partition structure 2 further includes pipe passing parts 26 that are all connected to the partition plate 21 and correspond to the pipes 1 one by one. The pipe passing parts 26 and the partition plate 21 enclose a passing hole 23, and the pipes 1 are disposed through the passing hole 23 in an interference fit manner.

[0066] Passing the pipes 1 through the passing hole 23 in an interference fit manner can play a role in fixing the pipes 1, facilitating the control of the on-off of the pipes 1 by the cooperation of the pressing part 312 and the elastic reset part 32, and preventing the pipes 1 from shaking and affecting the accuracy of the on-off control of the pipes 1.

[0067] Furthermore, the partition structure 2 is an integrally formed structural member, with a simple structure, easy to form, reducing the number of parts, lowering the cost, and being beneficial to the miniaturization of the flushing and suction device.

[0068] Furthermore, as Figure 2 and Figure 3 shown, the support base 22, the reset mounting part 25, and the reset limiting part 27 are arranged in sequence along the extension direction of the pipe 1. The support base 22 has an inclined surface for supporting the pipe 1, the inclined surface is parallel to the first direction, and the inclined surface is arranged towards the side where the reset mounting part 25 is located.

[0069] With such a setting, it is beneficial for the inclined surface to support the pipe 1 and cooperate with the pressing part 312 to control the on-off of the pipe 1.

[0070] Furthermore, as Figure 3 and Figure 4 shown, the partition structure 2 is arranged inside the flushing and suction housing. First positioning parts 24 are arranged on both sides of the partition structure 2 in the first direction. Second positioning parts 53 corresponding to the first positioning parts 24 one by one are arranged on the inner wall of the flushing and suction housing. The first positioning parts 24 and the second positioning parts 53 are inserted and abutted along the first direction; two limiting support structures 54 are arranged on the inner wall of the flushing and suction housing, and the partition structure 2 is clamped between the two limiting support structures 54 along the second direction.

[0071] Specifically, the flushing and suction housing includes two half shells 5 with opposite openings and distributed along the first direction. The two half shells 5 are connected to enclose an installation chamber, and the partition structure 2 is arranged in the installation chamber.

[0072] The two half shells 5 are distributed in the first direction. The separation structure 2 is provided with two first positioning members 24 spaced along the axial direction of the pipeline 1 on each side in the first direction. The first positioning members 24 are protrusions provided in the positioning holes opened on the two side surfaces of the separation structure 2 in the first direction. The second positioning member 53 is a positioning post protruded from the inner wall of the half shell 5. The positioning post and the positioning hole are inserted and matched in the first direction to limit the separation structure 2 in the radial direction of the positioning hole.

[0073] The first positioning member 24 and the second positioning member 53 are abutted in the first direction. After connecting the two half shells 5, the separation structure 2 is clamped between the two half shells 5. Without adding a new structure for fixing the separation structure 2, the separation structure 2 can be prevented from shaking, and the stability of the separation structure 2 is improved.

[0074] In this embodiment, a limiting and supporting structure 54 is provided on the inner wall of each half shell 5. Each limiting and supporting structure 54 includes two limiting units 541 spaced in the second direction. The two ends of the separation structure 2 in the first direction are respectively clamped between the two limiting units 541. The two limiting units 541 are spaced in the second direction to support the separation structure 2 by using the limiting and supporting structure 54 to prevent the second positioning member 53 from separating from the half shell 5. Moreover, a space for passing through the pipeline 1 is formed between the four limiting units 541 of the two limiting and supporting structures 54, so that the limiting and supporting structure 54 does not affect the passing through of the pipeline 1.

[0075] Exemplarily, the second positioning member 53, the limiting and supporting structure 54 and the corresponding half shell 5 are all integrally formed structural members. Such a setting can simplify the processing and reduce the cost.

[0076] Further, as Figure 1 and Figure 5 shown, one of the two on-off switches 31 is a flushing on-off switch 31b, and the other is a suction on-off switch 31a. The flushing and suction device further includes a suction speed regulating switch 6 rotatably installed on the flushing and suction housing; one end of the suction speed regulating switch 6 is located outside the flushing and suction housing, and the other end is located inside the flushing and suction housing and a spiral speed regulating surface 62 is provided at this end. The spiral speed regulating surface 62 spirally extends along the circumferential direction of the suction speed regulating switch 6. One end of the operating portion 311 of the suction on-off switch 31a is provided with a speed regulating portion 314. The speed regulating portion 314 axially abuts against the spiral speed regulating surface 62 along the suction speed regulating switch 6.

[0077] During the process of rotating the suction speed regulating switch 6, different positions of the spiral speed regulating surface 62 abut against the speed regulating portion 314. The spiral speed regulating surface 62 pushes the speed regulating portion 314 to make the suction on-off switch 31a rotate around a preset axis, so that the extrusion degree of the suction pipeline 1a by the extrusion portion 312 is different, that is, the opening degree of the suction pipeline 1a is adjusted.

[0078] Further, as shown in Figure 1 and Figure 6 , a speed regulation scale 61 is provided at one end of the suction speed regulation switch 6 located outside the flushing suction housing. By providing the speed regulation scale 61, it is convenient for the user to accurately adjust the opening degree of the pipeline 1 according to the speed regulation scale 61.

[0079] In this embodiment, the suction speed regulation switch 6 has an inner end and an outer end axially opposite to each other. The inner end is located inside the flushing suction housing, and the outer end is located outside the flushing suction housing. The speed regulation scale 61 is provided on the end face of the outer end, and a rotation mark is also provided on the end face of the outer end for marking the rotation direction of the opening degree of the suction pipeline 1a from large to small. With such a setting, it is convenient for the user to accurately select the rotation direction of the suction speed regulation switch 6 according to the needs. In other embodiments, the rotation mark can also be for marking the rotation direction of the opening degree of the suction pipeline 1a from small to large.

[0080] Further, as shown in Figure 1 and Figure 5 , a fully open abutting surface 63 and a cut-off abutting surface 64 are provided at the inner end of the flushing suction housing. Both the fully open abutting surface 63 and the cut-off abutting surface 64 are perpendicular to the axis of the suction speed regulation switch 6. The fully open abutting surface 63, the spiral speed regulation surface 62, and the cut-off abutting surface 64 are arranged in sequence along the circumferential direction of the suction speed regulation switch 6. The fully open abutting surface 63 is connected to one end of the speed regulation spiral surface close to the outer end.

[0081] When the speed regulation part 314 abuts against the fully open abutting surface 63 along the axis of the suction speed regulation switch 6, the opening degree of the suction pipeline 1a is the largest; when the speed regulation part 314 abuts against the cut-off abutting surface 64 along the axis of the suction speed regulation switch 6, the opening degree of the suction pipeline 1a is the smallest.

[0082] To facilitate the rotation of the suction speed regulation switch 6, both ends of the spiral speed regulation surface 62 are smoothly and transitionally connected to the fully open abutting surface 63 and the cut-off abutting surface 64 respectively, so that the opening degree of the suction pipeline 1a changes continuously and smoothly.

[0083] When it is necessary to keep the suction pipeline 1a at a certain opening degree, after rotating the suction speed regulation switch 6 to the corresponding speed regulation scale 61, there is no need to manually operate the on-off switch 31 anymore, and the suction pipeline 1a can be kept at the current opening degree. At this time, it is impossible to further reduce the opening degree of the suction pipeline 1a by operating the suction on-off switch 31a, but the opening degree of the suction pipeline 1a can be increased by operating the suction on-off switch 31a.

[0084] Further, as shown in Figure 2 , Figure 4 , Figures 7 to 9As shown, an embodiment of the present utility model further provides a pipeline fixing structure. The flushing and suction device further includes this pipeline fixing structure 4, which is used to limit two pipelines 1 simultaneously along the axial direction, the first direction, and the second direction of the pipeline 1, so as to fix the pipeline 1 to the flushing and suction housing and prevent the pipeline 1 from shaking.

[0085] Specifically, the pipeline fixing structure 4 includes pipeline joints 41, a first limiting member 42, and a second limiting member 43. Among them, there are two pipeline joints 41, and the two pipeline joints 41 are arranged side by side along the first direction. The two pipeline joints 41 are arranged in one-to-one correspondence with the two pipelines 1. Each pipeline 1 includes two sub-pipelines 11, and the two sub-pipelines 11 are respectively connected to both ends of the corresponding pipeline joint 41.

[0086] There are two first limiting members 42. Any pipeline joint 41 is fixed to the two first limiting members 42, and the two second limiting members 43 are both clamped between the two first limiting members 42 along the axial direction of the pipeline joint 41.

[0087] The second limiting member 43 is connected to the flushing and suction housing. There are two second limiting members 43 and they are arranged in one-to-one correspondence with the two pipeline joints 41. The second limiting member 43 includes a first limiting portion 431 and two second limiting portions 432 spaced apart along the second direction. The pipeline joint 41 is clamped between the two first limiting portions 431 of the corresponding second limiting member 43 along the second direction, and the two pipeline joints 41 are clamped between the first limiting portions 431 of the two second limiting members 43 along the first direction.

[0088] Clamping the second limiting member 43 between the two first limiting members 42 along the axial direction of the pipeline 1 realizes limiting the pipeline joint 41 along the axial direction of the pipeline 1; the two pipeline joints 41 are clamped between the first limiting portions 431 of the two second limiting members 43 along the first direction, realizing limiting the pipeline joint 41 along the first direction; clamping the pipeline joint 41 between the two first limiting portions 431 of the corresponding second limiting member 43 along the second direction, realizing limiting the pipeline joint 41 along the second direction.

[0089] The flushing pipeline 1b and the suction pipeline 1a share a pipeline fixing structure 4. This pipeline fixing structure 4 is relatively simple, with a small number of components, and there is no need to use connection structures such as fasteners. Only by limiting the pipeline joint 41 from the first direction, the second direction, and the axial direction of the pipeline 1 can the pipeline 1 connected to the pipeline joint 41 be limited. The installation method is simple, the disassembly and assembly are convenient and fast, the structure is simple, and the occupied space is small.

[0090] Clamping the second limiting member 43 between the two first limiting members 42 along the axial direction of the pipeline 1 can greatly increase the axial pulling force of the pipeline 1, thereby effectively preventing the axial pulling phenomenon of the pipeline 1.

[0091] In this embodiment, a slot is provided on any second limiting member 43, and the opening of the slot faces the other second limiting member 43; the bottom wall of the slot forms a first limiting portion 431, and the two side walls of the slot opposite to each other along the second direction each form a second limiting portion 432.

[0092] The flushing pipe 1b and the suction pipe 1a are sandwiched between the two first limiting portions 431 along the first direction, and the first pipe 1 is sandwiched between the two second limiting portions 432 corresponding to the second limiting members 43 along the second direction.

[0093] Exemplarily, the card slot is a U-shaped slot. In other embodiments, the card slot can also be a C-shaped card slot.

[0094] Furthermore, any first position-limiting member 42 is integrally formed with any pipe joint 41. This arrangement can improve the connection stability between the first position-limiting member 42 and the pipe joint 41.

[0095] Furthermore, if Figure 2 and Figure 8 As shown, the sub-pipeline 11 and the pipe joint 41 are plugged in in an interference fit manner. The connection between the sub-pipeline 11 and the pipe joint 41 is simple and easy to assemble and disassemble.

[0096] Furthermore, if Figure 2 and Figure 8 As shown, a sealant, such as UV glue, is provided between the sub-pipeline 11 and the pipe joint 41. This arrangement can prevent leakage at the connection position between the sub-pipeline 11 and the pipe joint 41 and improve the sealing performance.

[0097] Furthermore, if Figure 4 As shown, the pipeline fixing structure 4 is arranged in the installation chamber; the two second limiting members 43 are fixed to the inner walls of the corresponding half shells 5 in a one-to-one correspondence.

[0098] In this embodiment, a reinforcing rib 433 is connected between the half shell 5 and the second limiting member 43. The reinforcing rib 433 improves the connection stability between the half shell 5 and the second limiting member 43 and prevents the second limiting member 43 from shaking.

[0099] Exemplarily, the second position-limiting member 43 is provided with reinforcing ribs 433 at both ends of the second position-limiting member 43 in the second direction, so as to fully utilize the space at both ends of the second position-limiting member 43 in the second direction.

[0100] Furthermore, if Figure 4 As shown, the second position-limiting member 43 and the reinforcing rib 433 are integrated with the corresponding half shell 5 to form an integrally formed structural member. This arrangement can simplify the installation of the second position-limiting member 43 and the reinforcing rib 433.

[0101] Example 2

[0102] The difference between this embodiment and the first embodiment is that Figure 10 and Figure 11 As shown, the elastic return member 32 is a telescopic spring 32a, and the partition structure 2 also includes a return mounting portion 25 corresponding one-to-one to the pipe 1 and connected to the partition plate 21. The elastic return member 32 is arranged between the extrusion portion 312 and the return mounting portion 25.

[0103] Exemplarily, the telescopic spring 32 a is a compression spring, and the reset mounting portion 25 is located on a side of the extrusion portion 312 facing away from the support base 22 .

[0104] Specifically, a first mounting groove is defined on the side of the extrusion portion 312 facing away from the support base 22, and a second mounting groove is defined on the side of the reset mounting portion 25 facing the extrusion portion 312. One end of the telescopic spring 32a is positioned in the first mounting groove, and the other end is positioned in the second mounting groove. This arrangement prevents the switch telescopic spring 32a from bending or twisting.

[0105] In other embodiments, the telescopic spring 32 a may also be configured as a tension spring, and the reset mounting portion 25 is located on a side of the extrusion portion 312 facing the support base 22 .

[0106] Furthermore, if Figure 12 and Figure 13 As shown, the extrusion portion 312 is provided with an arc-shaped groove on the side facing the pipe 1, and the support base 22 is provided with an arc-shaped boss 221 on the side facing the pipe 1. The pipe 1 can be clamped between the arc-shaped boss 221 and the inner wall of the arc-shaped groove to cut off the pipe 1.

[0107] Such a configuration is conducive to the cooperation between the arc-shaped boss 221 and the arc-shaped groove to cut off the pipe 1, thereby improving the cutting effect and avoiding leakage after the pipe 1 is cut off.

[0108] In this embodiment, if Figure 11 、 Figure 13 and Figure 14 As shown, the partition structure 2 is provided with a plurality of first positioning members 24 on either side of the first direction, and the plurality of first positioning members 24 are arranged in two rows along the second direction. For example, the first positioning members 24 are positioning posts integrally formed with the partition structure 2, and the second positioning members 53 are positioning bosses protruding from the inner wall of the half shell 5. The positioning bosses are provided with positioning holes, into which the positioning posts are axially inserted. The partition structure 2 is sandwiched between the positioning bosses on the two half shells 5 along the first direction. There is no need to separately provide a structure for mounting and fixing the partition structure 2. The partition structure 2 can be secured within the irrigation and suction housing by simply using the plurality of first positioning members 24 and the plurality of second positioning members 53, resulting in a simple structure and low cost.

[0109] Exemplarily, the first positioning members 24 located on both sides of the partition structure 2 in the first direction are arranged in one-to-one correspondence, and the correspondingly arranged first positioning members 24 are integrally formed into a long rod.

[0110] It should be noted that, in this embodiment, the two arc-shaped bosses 221 also each serve as a first positioning member 24, reducing the number of components and improving the integration of the partition structure 2.

[0111] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
