[0068] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and examples.

[0069] As described in the background, the overall structure of the existing peristaltic pump is relatively complex, and when the pump pipe, roller group and other components are maintained / replaced, the pump shell, fasteners and other parts need to be disassembled, and when installed, the seal needs to be re-matched, and the operation steps are relatively complex. These problems limit the convenience of using the peristaltic pump, especially in the scene where the pump pipe needs to be frequently replaced and the pump group needs to be maintained.

[0070] In view of the above problems, the embodiment of the present application provides a modular quick release peristaltic pump, which integrates the pump pipe 132 and the pipe support 131 into one to form a pump pipe module 130, and integrates the pump seat module 110, the driving module 120 and the pump pipe module 130 into one to form a pump group 100, which can realize the whole disassembly and assembly of the pump pipe module 130 and the pump group 100, simplifies the replacement / maintenance operation, and improves the convenience.

[0071] Specifically, the modular quick release peristaltic pump of the embodiment of the present application comprises:

[0072] The fixed base plate 200 is provided with a pipe joint 300;

[0073] The pump group 100 comprises:

[0074] The pump seat module 110 is detachably connected to the fixed base plate 200 through the first quick release mechanism 400, and the inside of the pump seat module 110 is provided with a fluid passage 115, and the first end of the fluid passage 115 is opposite to the pipe joint 300 and is provided with a first deformation sealing joint 116;

[0075] The driving module 120 is fixedly arranged in the pump seat module 110 and comprises a roller group 121 and a driving unit for driving the roller group 121;

[0076] The pump pipe module 130 comprises a pipe frame 131 detachably connected to the pump base module 110 through the second quick release mechanism 500 and a pump pipe 132 integrated on the pipe frame 131, a pipe opening of the pump pipe 132 is opposite to the second end of the fluid channel 115 and is provided with a second deformation sealing joint 133; wherein,

[0077] When the first quick release mechanism 400 is locked:

[0078] The first deformation sealing joint 116 is compressed between the fixed base plate 200 and the pump base module 110, so that the pipe joint 300 and the first end of the fluid channel 115 form a first sealed connection;

[0079] When the second quick release mechanism 500 is locked:

[0080] The roller group 121 extrudes the pump pipe 132 to generate a preset working deformation;

[0081] The sealing compression surface 114 of the pump base module 110 synchronously compresses the second deformation sealing joint 133, so that the pump pipe 132 and the second end of the fluid channel 115 form a second sealed connection.

[0082] According to the peristaltic pump of the embodiment of the present application, the first quick release mechanism 400 and the second quick release mechanism 500 are used to realize the hierarchical coupling of the fixed base plate 200 and the pump group 100 and the pump group 100 and the pump pipe module 130, the rigid structure of the traditional peristaltic pump is broken, the pump group 100 and the pump pipe module 130 can be pre-integrated, the whole can be disassembled and replaced, and the replacement and maintenance efficiency is improved.

[0083] Moreover, the effect of "locking to seal the waterway" can be realized, and a fluid path of the pipe joint 300→static sealing→the fluid channel 115→dynamic sealing→the pump pipe 132 is constructed: after the first quick release mechanism 400 is locked, the first deformation sealing joint 116 is compressed to establish the static sealing of the pipe joint 300 of the fixed base plate 200 and the first end of the fluid channel 115, and the external environment is isolated; after the second quick release mechanism 500 is locked, the second deformation sealing joint 133 is compressed to establish the dynamic sealing of the pump pipe 132 of the pump pipe module 130 and the second end of the fluid channel 115, and the roller group 121 is pressed synchronously to force the pump pipe 132 to generate a preset working deformation to establish a pumping power, wherein the dynamic sealing can self-adaptively compensate the running vibration of the pump pipe 132 to ensure the sealing stability. The two-stage sealing is realized through a single operation, that is, the mechanical assembly and the sealing connection of the waterway are synchronously completed, the effect of "locking to seal the waterway" is realized, the limitation that the traditional peristaltic pump needs to be calibrated in multiple steps during disassembly and assembly is broken, and the disassembly and assembly efficiency is significantly improved. On the basis of ensuring the modular quick disassembly and assembly of the peristaltic pump, the sealing performance is also ensured.

[0084] The modular quick-release peristaltic pump provided by the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0085] Figure 1 And Figure 2 is a schematic view of the three-dimensional structure of the peristaltic pump of the embodiment of the present application. As shown in Figure 1 And Figure 2 , the peristaltic pump mainly consists of a fixed base plate 200 and a pump set 100. The fixed base plate 200 serves as the mounting reference platform of the system and can be firmly fixed on a workbench or a matching device by means of fasteners such as bolts, thereby providing stable mechanical support for the entire pump set 100. Figure 1 And Figure 2 , the fixed base plate 200 is a square plate, but the embodiment is not limited thereto, and the shape thereof can also be a regular or irregular shape such as a circle or a trapezoid.

[0086] Continuing to refer to Figure 2 , the fixed base plate 200 is provided with two pipe joints 300, which are respectively an inlet joint and an outlet joint, for connecting external inlet and outlet pipelines, respectively, so as to realize the inlet and outlet of the pump set 100. It should be understood that in other embodiments, the number of pipe joints 300 can also be three or more, so that the pump set 100 has multiple inlet joints / outlet joints to match the pumping of different materials.

[0087] In the embodiment, the two side surfaces of the fixed base plate 200 in the thickness direction are defined as a first surface 210 and a second surface 220, respectively, as shown in Figure 3 And Figure 4 , the first surface 210 is the side surface of the fixed base plate 200 facing away from the pump set 100, and the second surface 220 is the side surface of the fixed base plate 200 facing toward the pump set 100.

[0088] Continuing to refer to Figure 4 And Figure 14 , the fixed base plate 200 is provided with a through hole penetrating in the thickness direction, and the inner end (i.e., the end assembled with the pump set 100) of the pipe joint 300 extends to the second surface 220 of the fixed base plate 200 through the through hole, thereby forming a compression end for extruding the first deformation sealing joint 116; the outer end (i.e., the end connected with the external pipeline) of the pipe joint 300 is located at the first surface 210 of the fixed base plate 200, so as to facilitate the connection of the pipe joint 300 with the external pipeline.

[0089] Continuing to refer to Figure 4 And Figure 14The inner end of the pipe joint 300 is further provided with an annular limiting step 310, the outer diameter of the limiting step 310 is greater than the outer diameter of the through hole, when the pipe joint 300 is installed in place, the limiting step 310 abuts against the second surface 220 of the fixed base plate 200, realizing the axial positioning of the two, so as to facilitate the extrusion of the first deformation sealing joint 116 by the inner end of the pipe joint 300 when the pump group 100 moves close to the fixed base plate 200, realizing the sealing connection of the two.

[0090] Further, the second surface 220 of the fixed base plate 200 is further fixed with a pressing plate 320 through screws and other fixing members, the pressing plate 320 covers the limiting step 310, for pressing the inner end of the pipe joint 300, so as to ensure the stable positioning of the pipe joint 300 on the fixed base plate 200.

[0091] As shown in Figure 1 and Figure 2 , in the embodiment, the pump group 100 is integrally detachably connected to the second surface 220 of the fixed base plate, so as to facilitate the communication / conduction of the water circuit and the circuit of the pump group 100 with the water circuit (pipe joint 300) and the circuit of the fixed base plate 200.

[0092] Referring to Figure 6 , the pump group 100 of the embodiment specifically includes a pump seat module 110, a driving module 120 and a pump pipe module 130. The modules will be described in detail below.

[0093] Among them, as shown in Figure 7 , the driving module 120 includes a roller group 121 and a driving unit for driving the roller group 121. The roller group 121 here can adopt the existing peristaltic pump roller structure, and the structure thereof will not be described here. The driving unit adopts a motor 122, the output shaft of the motor 122 is connected to the roller group 121, so as to drive the roller group 121 to rotate.

[0094] Further, referring to Figure 4 , Figure 5 and Figure 14In the embodiment, a modular circuit coupling structure 123 is further arranged between the fixed substrate 200 and the driving module 120, which specifically includes a first circuit interface 1231 arranged in the driving module 120 and a second circuit interface 1232 arranged on the fixed substrate 200. The first circuit interface 1231 is connected to the control line of the motor 122, and the second circuit interface 1232 is used for external connection of an external power supply, a controller and the like. Here, the first circuit interface 1231 and the second circuit interface 1232 can adopt an existing plug-in needle array interface, and quick coupling and disassembly of the two can be achieved. In this way, during the assembly and disassembly of the pump set 100, the quick conduction of the circuit of the driving module 120 and the external circuit can be realized through the modular circuit coupling structure 123, the traditional wiring operation is eliminated, the efficiency is improved, the modular design of the pump set 100 is provided, and thus the peristaltic pump of the present application can be coupled / decoupled with the peristaltic pump waterway and the circuit through mechanical coupling / decoupling, so that the effect of one-step assembly / dismounting is achieved.

[0095] In some embodiments, the second circuit interface 1232 is mounted on the fixed substrate 200 through a radial floating structure, and can be adaptively adjusted in the plane direction of the fixed substrate 200 to actively align the first circuit interface 1231 during assembly, thereby improving the fault tolerance and reliability of the connection.

[0096] Specifically, referring to Figure 3 and Figure 4 , the second circuit interface 1232 is connected with a junction box (not labeled in the figure), and the fixed substrate 200 is provided with a mounting through hole through which the second circuit interface 1232 passes. The size of the mounting through hole is greater than that of the second circuit interface 1232, for example, the square-shaped second circuit interface 1232 and the through hole correspond to Figure 4 , and the length and width of the through hole can be slightly greater than those of the second circuit interface 1232, so that the second circuit interface 1232 has a movement allowance in the radial direction. At the same time, the upper and lower sides of the mounting through hole are both connected with screw holes, and the limit screw passes through the screw holes from the inside to the outside to connect with the junction box, so that the axis of the second circuit interface 1232 is limited in the fixed substrate 200. In addition, the diameter of the screw hole is greater than that of the rod part of the limit screw, so that the limit screw has a radial floating gap in the screw hole, which matches the radial floating gap of the second circuit interface 1232 in the mounting through hole. In this way, the axial positioning of the second circuit interface 1232 can be ensured, and the second circuit interface 1232 can be radially floated together with the junction box within a certain range.

[0097] In the pump pipe module 130, as shown in Figure 9As shown, the pump pipe module 130 comprises a pipe frame 131 and a pump pipe 132 integrated with the pipe frame 131. See Figure 9 and Figure 10 The pump pipe 132 of the embodiment is integrally arranged in a U shape, having a central extrusion section 1321 and two side delivery sections 1322. The extrusion section 1321 is in an arc-shaped pipe section structure, for forming working cooperation with the roller group 121, i.e. interacting with the roller group 121 to generate peristaltic conveying effect. The delivery section 1322 is a straight pipe section, and the two side delivery sections 1322 are respectively connected to the two ends of the extrusion section 1321. The delivery section 1322 is mainly used to provide a stable medium channel and connect the second deformation sealing joint 133. The design of the straight pipe section facilitates the accurate positioning of the second deformation sealing joint 133.

[0098] Continuing to refer to Figure 10 The second deformation sealing joint 133 of the embodiment has two, which are respectively arranged at the two pipe openings (i.e. the ends of the two delivery sections 1322) of the pump pipe 132. See Figure 9 and Figure 10 The second deformation sealing joint 133 can be specifically arranged in a flange shape coaxial with the pipe opening of the pump pipe 132, having a flat plane extrusion surface, facilitating uniform pressure distribution and ensuring reliable deformation. The coaxial arrangement also ensures the centration of the seal. At the same time, in order to ensure the deformation effect, the second deformation sealing joint 133 is made of a flexible deformable material, and preferably made of the same material as the pump pipe 132, such as silica gel, to ensure the consistency of material properties.

[0099] Further, the outer diameter (flange outer diameter) of the second deformation sealing joint 133 of the embodiment is greater than the outer diameter of the second end port of the fluid channel 115 on the pump seat module 110. In this way, when the two are centered, the port of the second end of the fluid channel 115 is located within the orthographic projection of the second deformation sealing joint 133 on the sealing press joint surface 114, and the outer edge of the flange can exceed the outer periphery of the port of the fluid channel 115, forming a complete annular coverage area, ensuring that the sealing surface completely contains the port of the fluid channel 115, eliminating the risk of edge leakage. In addition, it can also provide sufficient deformation contact area, enhance the sealing reliability, adapt to certain installation deviation, and ensure stable sealing performance under various working conditions.

[0100] As Figure 11As shown, the pipe rack 131 of the embodiment includes a main frame 1311 and a pipe body accommodating portion 1312 arranged in the main frame 1311. The main frame 1311 is arranged in a U shape. The U-shaped main frame 1311 can ensure that the profile of the main frame 1311 matches the trend of the pump pipe 132, and an open avoidance area is formed in the middle part, and the two side parts of the frame form a support structure that provides stable support. In this way, the avoidance area provides sufficient operating space for the roller group 121, and the U-shaped structure naturally guides the pump pipe 132 to form a working arc segment, ensuring precise alignment of the extrusion section 1321 and the roller group 121.

[0101] The pipe body accommodating portion 1312 of the pipe rack 131 is used to accommodate the pump pipe 132, as shown in Figure 9 and Figure 11 It adopts a U-shaped accommodating groove design that matches the shape of the pump pipe 132. Specifically, the accommodating groove is a groove body formed along the inner contour of the U-shaped main frame 1311. The openings of the accommodating grooves at different positions of the pump pipe 132 all point to the inner side of the main frame 1311, so that the pump pipe 132 can be naturally inserted along the groove body, ensuring that the working segment shape remains stable, achieving high integration of the pump pipe 132 and the pipe rack 131, which not only ensures positioning accuracy but also maintains the ideal geometric shape of the working segment of the pump pipe 132.

[0102] In addition, as shown in Figure 9 , the second deformation sealing joint 133 of the pipe port at both ends of the pump pipe 132 is located outside the pipe body accommodating portion 1312 (i.e., the accommodating groove). Here, the outside refers to the outside of the front end (open end) of the main frame 1311, so that during assembly of the pipe rack 131 to the pump seat module 110, the second deformation sealing joint 133 can be in contact with the sealing compression surface 114 of the pump seat module 110 first, thereby ensuring planar sealing between the two.

[0103] Further, in the embodiment, a sealing positioning assembly is further provided between the pipe rack 131 and the second deformation sealing joint 133, which ensures precise positioning of the second deformation sealing joint 133, thereby maintaining the axial stability of the sealing interface. Specifically, as shown in Figure 9 and Figure 10As shown, the sealing positioning assembly of the embodiment includes a positioning ring 134 arranged at the front end of the pipe frame 131, which is sleeved on the pump pipe 132 and tightly fitted with the inner side end face of the second deformation sealing joint 133. Here, the inner side end face of the second deformation sealing joint 133 refers to the end face of the second deformation sealing joint 133 towards the extrusion section 1321. In addition, corresponding to the design of the two second deformation sealing joints 133, the positioning ring 134 of the embodiment is also designed as two, which are respectively located at the inner sides of the two second deformation sealing joints 133. In this way, the second deformation sealing joint 133 is ensured to maintain the preset extended position through mechanical limiting, guiding the sealing joint to preferentially contact the sealing surface of the pump seat module 110 during assembly, and maintaining the axial position stability during the extrusion deformation process. The inner side arrangement of the positioning ring 134 neither affects the deformation freedom of the sealing joint, nor can accurately control the working position, which significantly improves the sealing reliability.

[0104] In some embodiments, a stop portion (not shown in the figure) can also be arranged on the outer wall of the pump pipe 132. The stop portion can adopt an annular stop ring structure integrally formed with the pump pipe 132, which is arranged adjacent to the second deformation sealing joint 133. An annular positioning groove is formed between the stop portion and the second deformation sealing joint 133, and the positioning ring 134 is precisely embedded in the groove, with the two side end faces thereof abutting against the stop portion and the second deformation sealing joint 133 respectively, to realize double axial limiting. This structural design effectively enhances the axial positioning reliability of the second deformation sealing joint 133, completely eliminates the possible axial displacement during the working process, and ensures that the sealing interface always maintains a stable contact state.

[0105] Further, in the embodiment, the positioning ring 134 can be installed at the front end of the pipe frame 131 in a detachable and fixed manner. For example, the positioning ring 134 can be fixed at the front end of the pipe frame 131 through a buckle connection mechanism. In this way, the positioning ring 134 can be pre-assembled with the pump pipe 132 into an independent module, and then quickly connected with the pipe frame 131 through the buckle connection mechanism, which simplifies the alignment and installation process of the positioning ring 134 and the pump pipe 132, realizes split modular assembly, and improves the overall assembly efficiency.

[0106] Further, in the embodiment, a limiting assembly is arranged between the pipe frame 131 and the pump pipe 132 for realizing the axial positioning of the two. Specifically, referring to Figure 9 to Figure 11 The limiting assembly of the embodiment includes two parts cooperating with each other: an axial limiting portion 136 arranged on the outer wall of the pump pipe 132, and a limiting matching portion 135 arranged in the pipe frame 131. The axial limiting portion 136 can be a protruding structure protruding from the outer wall of the pump pipe 132, which can be made by an integral molding process, Figure 10 which exemplarily shows an embodiment in which the axial limiting portion 136 is in a square shape. Correspondingly, referring to Figure 11The limiting fitting part 135 includes a groove body, specifically a square groove 1351 matched with the axial limiting part 136 in shape, and the opening direction of the square groove 1351 is consistent with the opening direction of the accommodating groove of the main body frame 1311, that is, both are towards the inner side of the main body frame 1311. At the same time, the square groove 1351 has a blocking wall 1352 on both sides for axial limiting. In this way, when the pump pipe 132 is installed, the pump pipe 132 is embedded into the accommodating groove from the inner side of the main body frame 1311, in this process, the axial limiting part 136 of the pump pipe 132 is synchronously embedded into the square groove 1351 from this side, and the axial constraint is realized through the blocking walls 1352 on both sides, ensuring the accurate positioning of the pump pipe 132, preventing the axial movement of the pump pipe 132, facilitating the accurate cooperation of the extrusion section 1321 of the pump pipe 132 with the roller group 121. This design realizes reliable axial positioning function through simple mechanical structure, while maintaining the convenience of assembly.

[0107] Further, in the embodiment, the limiting assembly adopts a double-point positioning arrangement, for example, the axial limiting part 136 and the limiting fitting part 135 are both provided with two. Among them, the two axial limiting parts 136 are symmetrically arranged on the pump pipe 132 at positions adjacent to both ends of the extrusion section 1321, and the limiting fitting part 135 is correspondingly arranged on both inner sides of the main body frame 1311. In this way, a double-restraint structure is formed, which synchronously implements axial constraint at both ends of the extrusion section 1321, effectively controls the axial displacement of the working section (extrusion section 1321) of the pump pipe 132, ensures the cooperation accuracy of the extrusion section 1321 and the roller group 121, avoids the position drift of the extrusion section 1321 during work, and maintains stable extrusion deformation effect.

[0108] Regarding the pump seat module 110, as shown in Figure 7 and Figure 8 , the pump seat module 110 of the embodiment also adopts a modular structure design, which specifically includes three main structural parts: the upper seat 111, the base 112 and the back seat 113. Among them, the upper seat 111 and the base 112 are arranged in parallel from top to bottom, maintaining a predetermined distance between them, and the back seat 113 is fixedly connected to the rear end of the upper seat 111 and the base 112 in the vertical direction. In this way, the three can be connected into an integrated structure to form a modular pump seat module 110, facilitating the assembly, disassembly, replacement and maintenance of the pump group 100 composed of the pump pipe 132, the pump seat module 110 and other modules.

[0109] Among them, the specific assembly relationship between the pump pipe module 130, the drive module 120 and the pump group 100 module can be as follows: the drive module 120 is fixed on the pump group 100 module to form an integral whole, for example, in Figure 6In the example, the driving module 120 is fixed on the upper seat 111 as a whole by means of screws or other fixing members; and the pump pipe module 130 is detachably coupled with the pump seat module 110 through the second quick release mechanism 500, so as to realize the separate assembly and disassembly and replacement of the pump pipe module 130, and further realize the hierarchical coupling of the pump pipe module 130, the pump group 100 and the fixed base plate 200.

[0110] Specifically, referring to Figure 8 In the embodiment, the upper seat 111, the bottom seat 112 and the back seat 113 jointly form a middle accommodating cavity, which is a special assembly cavity 117 for the pump pipe module 130, for accommodating and positioning the pump pipe module 130.

[0111] Correspondingly, in order to ensure the functional cooperation of the pump pipe module 130 with the roller group 121 and the second end of the fluid channel 115, the roller group 121 and the second end of the fluid channel 115 are integrated in the assembly cavity 117 of the pump seat module 110, so that after the pump pipe module 130 is assembled into the cavity, it can automatically realize the extrusion cooperation with the roller group 121 and the sealing connection with the second end of the fluid channel 115.

[0112] Among them, about the roller group 121, see Figure 7 and Figure 8 The roller group 121 of the embodiment is located in the assembly cavity 117, and the upper end of the roller group 121 is connected with the upper seat 111 through a rotating pair of shafts, and is connected with the motor 122 located above the upper seat 111, and the lower end is connected with the bottom seat 112 through a rotating pair of shafts, so as to ensure that the roller group 121 is stably supported in the assembly cavity 117.

[0113] Among them, the second end of the fluid channel 115 integrated in the assembly cavity 117 of the pump seat module 110 can be integrated on the inner side wall surface of the back seat 113 facing the assembly cavity 117, so that the pump pipe 132 can be cooperated with the second end of the fluid channel 115 after being assembled into the assembly cavity 117. Specifically, referring to Figure 7 and Figure 14 The fluid channel 115 extends through the thickness direction of the back seat 113, and the port of the first end faces the fixed base plate 200, and the port of the second end points to the assembly cavity 117, i.e. is formed on the inner side wall surface of the back seat 113 facing the assembly cavity 117.

[0114] And, corresponding to the design of the two pipe openings of the pump pipe 132 and the two pipe joints 300 of the fixed base plate 200, the back seat 113 is also provided with two fluid channels 115, which are respectively used for feeding and discharging, so that when the two pipe openings of the pump pipe 132 and the two pipe joints 300 are respectively connected to the two fluid channels 115, the feeding and discharging of the pump pipe 132 can be realized.

[0115] Corresponding to the structure design that the fluid channel 115 is integrated in the back seat 113, see Figure 7 In the present embodiment, the sealing press surface 114 in the pump seat module 110 for cooperating with the second deformation sealing joint 133 refers to the inner side wall surface of the back seat 113 facing the assembly cavity 117. When the second deformation sealing joint 133 of the pump pipe module 130 is pressed to the inner side wall surface of the back seat 113 to form a flat sealing, the second deformation sealing joint 133 is just connected with the second end of the corresponding fluid channel 115.

[0116] In the present embodiment, the first end of the fluid channel 115 is provided with a first deformation sealing joint 116. Specifically, see Figure 5 and Figure 14 The first deformation sealing joint 116 is a flexible sealing pad, which can be made of flexible and deformable materials such as silica gel, and the first deformation sealing joint 116 is at least partially protruded from the side of the back seat 113 of the pump seat module 110 away from the assembly cavity 117. The flexible sealing pad is provided with a hole in the middle, which is connected with the port of the first end of the fluid channel 115. In this way, when the pump seat module 110 is locked to the fixed base plate 200 through the first quick release mechanism 400, the pipe joint 300 on the fixed base plate 200 axially presses the first deformation sealing joint 116 to make it elastically deformed, so as to form two sealing interfaces between the end surface of the back seat 113 and the end surface of the pipe joint 300, and realize reliable sealing connection between the fluid channel 115 and the pipe joint 300.

[0117] Further, see Figure 5 The surface of the side of the back seat 113 away from the assembly cavity 117 is further provided with a positioning recess 118, the contour of the positioning recess 118 covers the first end opening of the fluid channel 115, the first deformation sealing joint 116 is embedded in the positioning recess 118, and at least part of the first deformation sealing joint 116 is radially misaligned with the first end opening of the fluid channel 115. For example, in Figure 5In the example, the positioning cavity 118 is a circular cavity coaxial with the fluid channel 115, and the diameter of the circular cavity is larger than the diameter of the fluid channel 115. Correspondingly, the first deformable sealing joint 116 adopts an annular structure, the inner diameter of which is approximately equal to the diameter of the fluid channel 115, and the outer diameter is larger than the diameter of the fluid channel 115 and slightly smaller than the diameter of the circular cavity. The inner hole of the first deformable sealing joint 116 serves as a connecting hole for docking with the fluid channel 115. The outer diameter of the first deformable sealing joint 116 is larger than the diameter of the fluid channel 115, which ensures that the first deformable sealing joint 116 is at least partially radially misaligned with the fluid channel 115. When squeezed by the pipe joint 300, the first deformable sealing joint 116 can fully abut against the bottom surface of the cavity, achieving effective sealing deformation. The design that the outer diameter of the first deformable sealing joint 116 is slightly smaller than the diameter of the circular cavity ensures a uniform gap between the first deformable sealing joint 116 and the side wall of the positioning cavity 118, providing the necessary deformation space for the first deformable sealing joint 116 in the circumference, which can accommodate the radial expansion generated when the first deformable sealing joint 116 is compressed, thereby ensuring the stability of the sealing effect.

[0118] Furthermore, a positioning structure is provided between the first deformable sealing joint 116 and the pump base module 110 to ensure precise alignment and stable connection between the two. See also Figure 5 and Figure 14 The positioning structure includes at least two extensions 1161 disposed on the circumferential outer side of the first deformable sealing joint 116, and these extensions 1161 are preferably symmetrically distributed (e.g., Figure 5 As shown in the diagram, the extension 1161 is arranged symmetrically in the upper and lower directions. In the axial direction, the surface of the extension 1161 does not extend beyond the surface of the back seat 113 on that side, thus preventing it from being squeezed by the pipe joint 300. The back seat 113 is provided with a through hole (not labeled in the figure) corresponding to the position of the extension 1161. Each extension 1161 has a limiting part 1162 extending toward the back seat 113. The limiting part 1162 passes through the corresponding through hole, and the end of the limiting part 1162 (the end away from the extension 1161) forms a limiting end with a diameter larger than the diameter of the through hole. This arrangement ensures the radial positioning of the first deformable sealing joint 116, keeps the first deformable sealing joint 116 coaxial with the circular cavity, and maintains a uniform gap with the side wall of the positioning cavity 118. This ensures that the sealing joint deforms uniformly in all directions when under pressure, and also ensures installation stability, guaranteeing that the first deformable sealing joint 116 is securely installed in the circular cavity.

[0119] like Figure 6 As shown, in this embodiment, the pump pipe module 130 is integrally inserted into the assembly cavity 117 of the pump base module 110. That is, the detachable connection between the pipe bracket 131 and the pump base module 110 in this embodiment is a plug-in connection. Specifically, as follows: Figure 6As shown, the pump pipe module 130 is inserted into the assembly cavity 117 in a direction perpendicular to the inner side wall surface of the back seat 113 (i.e. Figure 6 the X direction shown) to form a precise positioning plug-in fit with the pump seat module 110. In this way, the pump pipe module 130 can be quickly plugged in and out, which is more convenient than other matching methods and improves the replacement efficiency.

[0120] Further, referring to Figure 6 In this embodiment, the outer profile of the pipe holder 131 matches the outer profile of the assembly cavity 117, i.e., the thickness of the main frame 1311 is the same as the thickness of the assembly cavity 117, the width is the same as the width of the assembly cavity 117, the profile curvature radius of the arc segment (i.e., the end opposite to the open end of the pipe holder 131) matches the profile curvature radius of the end of the upper seat 111 / the base 112, etc. In this way, after the pump pipe module 130 is assembled to the pump seat module 110, the outer surface of the pump group 100 is flush and the overall profile is regular, which not only realizes quick plugging and unplugging, but also significantly improves the appearance integration and protection performance of the equipment.

[0121] In this embodiment, a linear guide structure is further provided between the pipe holder 131 and the pump seat module 110 to ensure the directional assembly of the pump pipe module 130 and realize the precise alignment of the pump pipe 132 with the roller group 121 and the second deformation sealing joint 133 with the fluid passage 115. Specifically, referring to Figure 7 The linear guide structure of this embodiment can include a linear guide groove 141 extending in the X direction and a guide slider 142 matching the linear guide groove 141. One of the linear guide groove 141 and the guide slider 142 is provided on the pipe holder 131, and the other is provided on the pump seat module 110, for example, the linear guide groove 141 can be provided on the upper seat 111 and the base 112 at the same time, and the guide slider 142 can be provided on the upper and lower surfaces of the pipe holder 131. Moreover, when the guide slider 142 and the linear guide groove 141 are matched, the extrusion section 1321 of the pump pipe 132 is aligned with the roller group 121, and the second deformation sealing joint 133 is aligned with the second end of the fluid passage 115. Here, the alignment can be understood as the axial relative position in the X direction.

[0122] Further, in the embodiment, the arrangement between the extrusion section 1321 of the pump pipe 132 and the second deformation sealing joint 133 and between the roller set 121 and the second end of the fluid channel 115 also satisfies the following condition: the extrusion section 1321 of the pump pipe 132 is in the shape of a circular arc, the assembly direction of the pipe holder 131 is a linear direction, i.e., the X direction, and in the linear direction, the axial distance between the center of the circle where the extrusion section 1321 is located and the outer end surface of the second deformation sealing joint 133 is greater than the axial distance between the rotation center of the roller set 121 and the sealing compression surface 114. It should be understood that, during the installation of the pump pipe 132, the center of the circle where the extrusion section 1321 of the pump pipe 132 is located is usually arranged concentrically with the rotation center of the roller set 121, so as to realize the uniform extrusion of the extrusion section 1321 of the pump pipe 132 by the roller set 121 and ensure the uniform pumping effect. Based on this, the embodiment controls the axial distance between the center of the circle where the extrusion section 1321 is located and the outer end surface of the second deformation sealing joint 133 to be greater than the axial distance between the rotation center of the roller set 121 and the sealing compression surface 114, so that when the pump pipe 132 is assembled to the center of the circle where the extrusion section 1321 is located coincides with the rotation center of the roller set 121 and the extrusion section 1321 generates a preset working deformation, the second deformation sealing joint 133 at the front end of the pump pipe 132 has been in contact with and generates a preset deformation under the pressure of the sealing compression surface 114 of the pump seat module 110. Thus, the double deformations are realized through a single plugging action, the step of adjusting is eliminated, and the assembly in a real sense is achieved in one step. This synchronous mechanism significantly improves the installation efficiency and system reliability.

[0123] Referring to Figure 6 and Figure 7 In the embodiment, the second quick release mechanism 500 is arranged between the pump pipe module 130 and the pump seat module 110, and is used to lock the pump pipe module 130 to the pump seat module 110, so as to realize the separate assembly and disassembly of the pump pipe module 130.

[0124] In the embodiment, the second quick release mechanism 500 has a second unlocking state and a second locking state. When switched from the second unlocking state to the second locking state, the pump pipe module 130 is driven to displace towards the sealing compression surface 114 of the pump seat module 110, so that the second deformation sealing joint 133 generates a compression deformation. In this way, during the locking process, the locking of the pump pipe module 130 to the pump seat module 110 and the working deformation of the extrusion section 1321 of the pump pipe 132 and the sealing deformation of the second deformation sealing joint 133 can be realized synchronously through axial displacement, one-step assembly is realized, and the precise assembly of the pump pipe 132 is realized.

[0125] Specifically, referring to Figure 8 , Figure 11 and Figure 12The second quick release mechanism 500 comprises a rotating locking rod 510 rotatably arranged on the pipe support 131 and a locking matching part 540 arranged on the pump base module 110. The upper and lower ends of the rotating locking rod 510 extend to form an arc-shaped clamping part 511, which is specifically a semi-cylindrical contour.

[0126] Referring to FIG. 8 and Figure 12 The locking matching part 540 is arranged at the end of the upper seat 111 and the bottom seat 112 away from the back seat 113, and specifically comprises a guide channel 541, a locking cavity 542 and a locking protrusion 543. The contour of the locking cavity 542 matches the rotating track of the arc-shaped clamping part 511. For example, corresponding to the semi-cylindrical arc-shaped clamping part 511, the locking cavity 542 can be a cylindrical cavity with the same diameter as the arc-shaped clamping part 511, so that the arc-shaped clamping part 511 can rotate in the locking cavity 542 after entering the locking cavity 542. In addition, the rotating locking rod 510 and the locking cavity 542 also satisfy that when the pipe support 131 is aligned with the pump base module 110 in the X direction, the center line of the rotating locking rod 510 is coplanar with the center line of the locking cavity 542, so as to ensure that the arc-shaped clamping part 511 can rotate along the inner wall of the locking cavity 542 after entering the locking cavity 542.

[0127] Continuing to refer to Figure 12 The guide channel 541 extends from the outer end of the upper seat 111 and the bottom seat 112 to the locking cavity 542, so that the locking cavity 542 is in communication with the outside through the guide channel 541. Here, the guide channel 541 is arranged in the X direction. In addition, the width of the guide channel 541 allows the arc-shaped clamping part 511 to pass through and enter the locking cavity 542. For example, the width of the guide channel 541 is just equal to the radius of the arc-shaped clamping part 511, so as to ensure that the arc-shaped clamping part 511 passes through the guide channel 541 and enters the locking cavity 542 in a specified posture.

[0128] The locking protrusion 543 is used to limit the arc-shaped clamping part 511 when it is in the locking position. Specifically, referring to Figure 12 In the X direction, the guide channel 541 is opposite to one half of the locking cavity 542, and the locking protrusion 543 is opposite to the other half of the locking cavity 542. In the left-right direction, Figure 12 The guide channel 541 and the locking protrusion 543 are opposite to each other.

[0129] Based on the above structure design, the locking process is as follows:

[0130] Firstly, the rotating locking rod 510 is rotated to the unlocking position, and then the pipe support 131 is inserted into the pump base module 110 along the X direction. In this process, the arc-shaped clamping part 511 of the rotating locking rod 510 enters the locking cavity 542 through the guide channel 541. Since the rotating locking rod 510 has not been rotated to the locking position, and the second deformation sealing joint 133 axially limits the pipe support 131, the rotation center of the arc-shaped clamping part 511 does not coincide with the center of the locking cavity 542 at this time. Specifically, the rotation center of the arc-shaped clamping part 511 is located outside the center of the locking cavity 542, and the second deformation sealing joint 133 is not compressed in place at this time.

[0131] Then, the rotating locking rod 510 is counterclockwise rotated to the locking position, so that the arc surface of the arc-shaped clamping part 511 moves along the arc-shaped inner wall of the locking cavity 542. In this process, based on the limiting and guiding of the arc-shaped inner wall of the locking cavity 542, the arc-shaped clamping part 511 gradually moves to the position where the rotation center coincides with the center of the locking cavity 542. That is to say, during the rotation process, the arc-shaped clamping part 511 has a certain amount of axial displacement in the X direction, which exerts a directional force on the pipe support 131 in the X direction, until the extruded section 1321 of the pump pipe 132 and the second deformation sealing joint 133 reach the preset working deformation.

[0132] Finally, the arc-shaped clamping part 511 is rotated by 180 degrees and is just aligned with the locking protrusion 543 outside the locking cavity 542, while being out of alignment with the guide channel 541. At this time, the locking protrusion 543 limits the arc-shaped clamping part 511 in the X direction, thereby achieving the locking of the pump pipe module 130 and the pump base module 110.

[0133] On the contrary, the unlocking process is to rotate the rotating locking rod 510 clockwise, so that the arc-shaped clamping part 511 is aligned with the guide channel 541, and then the pump pipe module 130 can be pulled out.

[0134] Further, referring to Figure 11 , the middle part of the rotating locking rod 510 is further fixedly connected with a rotating handle 520, and the rotating handle 520 is perpendicular to the rotating locking rod 510. The end of the pipe support 131 is provided with a horizontally extending movable slot 530, and the rotating handle 520 is arranged in the movable slot 530. In this way, driving the rotating handle 520 to move clockwise or counterclockwise along the movable slot 530 can drive the rotation of the rotating locking rod 510, thereby achieving the locking or unlocking of the pipe support 131 and the pump base module 110, and the operation is convenient.

[0135] The pump set 100 composed of the pump base module 110, the driving module 120 and the pump pipe module 130 can be detachably fixed with the fixed base plate 200 through the first quick release mechanism 400, so as to realize the quick release and quick assembly of the whole pump set 100.

[0136] In the embodiment, the first quick release mechanism 400 has a first unlocking state and a first locking state. When switching from the first unlocking state to the first locking state, the pump base module 110 is driven to displace towards the fixed base plate 200, so that the first deformation sealing joint 116 is compressed and deformed. In this way, during the locking process, the pump base module 110 can be driven to displace towards the fixed base plate 200 to achieve the sealing deformation of the first deformation sealing joint 116, thereby achieving the effect of "locking and waterway sealing connection".

[0137] Specifically, referring to Figure 3 , Figure 13 , Figure 14 and Figure 15 , the first quick release mechanism 400 of the embodiment includes a driving rod 410 and a locking structure. Referring to Figure 13 , the driving rod 410 axially penetrates the pump base module 110 and the fixed base plate 200. The first end of the driving rod 410 is located on the side of the pump base module 110 and is provided with a rotating operation part 411. For example, in the example shown in Figure 13 , the first end of the driving rod 410 is located on the side of the upper seat 111 / bottom seat 112 away from the fixed base plate 200, and the rotating operation part 411 can be a hexagonal column head, which can be driven to rotate by using a tool. The second end of the driving rod 410 extends to the first face 210 of the fixed base plate 200. It should be understood that, in order to enable the driving rod 410 to penetrate the pump base module 110 and the fixed base plate 200 as a whole, the corresponding positions of the pump base module 110 and the fixed base plate 200 should be provided with axial through holes. The middle part of the driving rod 410 is provided with a radially protruding pushing block 430, which forms an axial limiting fit with the pump base module 110. For example, in the example shown in Figure 14 , the pushing block 430 is a cylindrical structure coaxially arranged with the driving rod 410, and the side of the back seat 113 facing the upper seat 111 / bottom seat 112 is formed with a cylindrical recess, and the pushing block 430 is embedded in the cylindrical recess. After the upper seat 111 / bottom seat 112 is assembled to the back seat 113, the pushing block 430 can be axially limited between the upper seat 111 / bottom seat 112 and the back seat 113.

[0138] Continuing to refer to Figure 13 , the locking structure includes a guide rod 420 fixed to the second end of the driving rod 410, which is crosswise arranged with the driving rod 410, thereby symmetrically forming two guide parts on the two radial sides of the driving rod 410. Referring to Figure 3The first side 210 of the fixed base plate 200 is provided with a rotating groove (not labeled in the figure). The rotating groove is a circular groove coaxial with the driving rod 410. The fixed base plate 200 is provided with a through hole 230 at a position corresponding to the rotating groove. The through hole 230 is a strip-shaped hole matched with the guide rod 420, so that the guide rod 420 can extend into the rotating groove through the strip-shaped hole. Correspondingly, to ensure the installation of the driving rod 410, the back seat 113 is also provided with a strip-shaped hole, so that the guide rod 420 can pass through the back seat 113 and extend to the first side of the fixed base plate 200.

[0139] Referring to Figure 3 and Figure 15 , the rotating groove is provided with a guide surface 450 extending in the circumferential direction and located on the rotating track of the guide rod 420. In the rotating direction of the guide rod 420, the distance between the guide surface 450 and the push block 430 continuously increases or decreases. For example, in the orientation shown in Figure 15 , the axial distance between the guide surface 450 and the push block 430 gradually increases in the counterclockwise direction, forming a smooth inclined surface. Specifically, the guide surface 450 has a highest point and a lowest point in the axial direction, and a smooth inclined surface with a continuous height change between the highest point and the lowest point, so that the guide surface 450 forms an inclined slope extending in the circumferential direction in the rotating groove, with a lift of a predetermined distance. When the guide rod 420 rotates along the guide surface 450, it can "climb" or "descend" to perform axial displacement. The lowest point of the guide surface 450 is connected to the through hole 230 in the axial direction.

[0140] Further, referring to Figure 15 , corresponding to the two guide portions formed by the guide rod 420, in this embodiment, two sets of guide surfaces 450 are arranged in the rotating groove to guide the two guide portions respectively.

[0141] Further, referring to Figure 3 and Figure 15 , in this embodiment, two limiting blocks 440 are also arranged in the rotating groove. The two limiting blocks 440 are respectively arranged at the ends of the two guide surfaces 450 and protrude axially outward from the ends of the corresponding guide surfaces 450. Each limiting block 440 includes a first limiting surface 441 and a second limiting surface 442 arranged at an angle of 90 degrees. The first limiting surface 441 is located at the end of the corresponding guide surface 450, and the second limiting surface 442 is located at the side wall of the through hole 230 on that side. In this way, when the two guide portions respectively abut against the second limiting surfaces 442 of the two limiting blocks 440, the guide rod 420 is directly opposite the through hole 230; when the two guide portions are respectively located at the highest points of the corresponding guide surfaces 450, the two guide portions respectively abut against the first limiting surfaces 441 of the two limiting blocks 440.

[0142] The operating principle of the first quick-release mechanism 400 based on the above structural design is as follows:

[0143] Initial state (unlocked state): In the axial direction, the guide rod 420 is aligned with the through hole 230, and the guide rod 420 is located at the lowest point of the guide surface 450. At this time, the first deformable sealing joint 116 is not squeezed, and a limit is formed between the pump base module 110 and the fixed base plate 200; in the circumferential direction, the guide rod 420 abuts against the second limiting surface 442 of the limiting block 440.

[0144] Locking process: Rotate drive rod 410, rotation direction is Figure 15 As shown, the guide rod 420 moves counterclockwise along the guide surface 450, causing the limiting part 1162 to move. Due to the change in the axial distance between the guide surface 450 and the pushing block 430, the guide rod 420 "climbs" along the guide surface 450, thereby causing the drive rod 410 to generate axial displacement. This displacement drives the pump seat module 110 to press against the fixed base plate 200 via the pushing block 430, compressing and deforming the first deformable sealing joint 116. At this time, the elastic restoring force of the first deformable sealing joint 116 generates an axial preload force acting on the pump seat module 110, allowing the guide rod 420 to stably abut against the guide surface 450. Of course, in other embodiments, a spring can also be provided on the side of the fixed base plate 200 facing the pump seat module 110. When the two are locked, the spring compression exerts an axial preload force on the pump seat module 110, ensuring that the guide rod 420 can stably abut against the guide surface 450.

[0145] Locked state: The guide rod 420 abuts against the first limiting surface 441 of the limiting block 440. At this time, the guide rod 420 is misaligned with the through hole 230 to achieve mechanical interlock.

[0146] Unlocking process: Rotate drive lever 410, the direction of rotation is... Figure 15 As shown, proceed clockwise until the guide rod 420 abuts against the second limiting surface 442 of the limiting block 440. At this point, the guide rod 420 is aligned with the through hole 230 and can be pulled outward to separate the pump assembly 100 and the fixed base plate 200.

[0147] In some embodiments, the end of the guide surface 450 (i.e., the end connected to the limiting stop 440) is provided with an axially recessed positioning recess 451. Based on this positioning recess 451, when the guide rod 420 is in the extreme position of the locked state, part of it will fall into the positioning recess 451, thereby constraining the circumferential rotation of the guide rod 420 and improving the locking stability.

[0148] Furthermore, in this embodiment, the first quick-release mechanism 400 is provided with multiple sets, for example... Figure 1 and Figure 2Exemplary shows that the first quick release mechanism 400 has four groups of embodiments, and the four groups of first quick release mechanisms 400 are distributed at four corners of the pump base module 110. In this way, when locking / unlocking the pump group 100, it is necessary to lock / unlock the four groups of first quick release mechanisms 400, which ensures stability.

[0149] Further, referring to Figure 2 to Figure 5 In the embodiment, a guide positioning assembly is further arranged between the fixed base plate 200 and the pump base module 110. The assembly includes at least two guide holes 610 arranged on the fixed base plate 200 and guide posts 620 arranged on the pump base module 110 and matched with the guide holes 610. For example, the guide holes 610 are circular hole structures, and the guide posts 620 are cylindrical structures, and the diameters of the two are matched, so that they can be gap-fitted. In this way, the guide positioning assembly can guide the axial displacement of the pump base module 110 relative to the fixed base plate 200 when the pump group 100 is assembled. When the guide posts 620 are inserted into the corresponding guide holes 610, the guide rods 420 of the first quick release mechanism 400 are automatically opposite to the through holes 230, realizing the directional assembly of the pump base module 110 and the fixed base plate 200, and ensuring quick and accurate positioning.
