[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0033] A peristaltic pump uses the peristaltic principle to transport liquids. It primarily consists of a motor, pump head, and hose. The pump head contains multiple rollers, or extrusion wheels, which squeeze the hose in a specific sequence, squeezing the liquid out and achieving directional transport.

[0034] However, traditional peristaltic pumps usually increase the flow rate by increasing the motor speed, which increases the power of the motor, increases energy consumption, and reduces the service life of the peristaltic pump.

[0035] In order to solve this technical problem, the present invention proposes an energy-saving peristaltic pump.

[0036] See also Figures 1 to 3 In one embodiment of the present invention, the energy-saving peristaltic pump includes a housing 100, an extrusion mechanism 400, a limiting mechanism 500 and a driving mechanism 600. The housing 100 is provided with a receiving space 101. The receiving space 101 receives a hose 200 and a limiting seat 300, and the hose 200 extends along the circumference of the limiting seat 300; one end of the extrusion mechanism 400 is detachably provided on the limiting seat 300, and the other end of the extrusion mechanism 400 abuts against the hose 200; the limiting mechanism 500 is received in the receiving space 101. The limiting mechanism 500 is arranged on one side of the limiting seat 300 corresponding to the position of the extrusion mechanism 400. The limiting mechanism 500 can move between a pressing position or a release position close to or away from the limiting seat 300, and correspondingly presses or releases the extrusion mechanism 400 against the limiting seat 300; the driving mechanism 600 is arranged on the housing 100, and the driving mechanism 600 is connected to the limiting mechanism 500, and is used to drive the limiting mechanism 500 to drive the extrusion mechanism 400 to move circumferentially along the limiting seat 300 when pressing against the extrusion mechanism 400.

[0037] Specifically, the peristaltic pump includes a housing 100, an extrusion mechanism 400, a limiting mechanism 500, and a drive mechanism 600. The housing 100 includes a receiving space 101, which houses a hose 200 and a limiting seat 300. The hose 200 extends circumferentially along the limiting seat 300, allowing the hose 200 to remain stable while being squeezed by the extrusion mechanism 400, thereby ensuring the peristaltic pump's delivery efficiency and accuracy.

[0038] One end of the squeezing mechanism 400 is detachably mounted on the stopper 300, allowing the squeezing mechanism 400 to be replaced with a squeezing wheel 420 of varying sizes or shapes to accommodate varying liquid flow rates or flow rates. The other end of the squeezing mechanism 400 abuts against the hose 200, physically squeezing the liquid within the hose 200 to move forward.

[0039] The limiting mechanism 500 is housed within the accommodating space 101 and is positioned on one side of the limiting seat 300, corresponding to the position of the extrusion mechanism 400. The limiting mechanism 500 can move between a contact position (closer to or farther from the limiting seat 300) and a release position, allowing for quick assembly and disassembly of the extrusion mechanism 400, increasing the peristaltic pump's adaptability to varying usage requirements and providing simple and efficient operation.

[0040] The driving mechanism 600 is disposed on the housing 100 and connected to the limiting mechanism 500. The driving mechanism 600 is used to drive the limiting mechanism 500 to move the extrusion mechanism 400 along the circumferential direction of the limiting seat 300 when the limiting mechanism 500 abuts against the extrusion mechanism 400. This makes the entire extrusion process more stable and also reduces the jamming and energy loss caused by improper movement of the extrusion mechanism 400.

[0041] More specifically, the energy-saving peristaltic pump of the present invention can adapt to different usage requirements under different liquid flow or flow rate requirements by replacing the extrusion mechanism 400 of different sizes and the rated power of the driving mechanism 600, thereby improving the adaptability and flexibility of the peristaltic pump.

[0042] In addition, compared with traditional peristaltic pumps, the peristaltic pump of the present invention does not need to increase the motor speed when increasing the flow rate, thereby avoiding the increased energy consumption and wear caused by high-speed operation. While reducing energy consumption, it not only extends the service life of the peristaltic pump, but also improves the adaptability and operational flexibility of the peristaltic pump.

[0043] In the technical solution provided by the present invention, the extrusion mechanism 400 of the peristaltic pump can be quickly replaced and adjusted through the detachable extrusion mechanism 400, the limiting mechanism 500 and the driving mechanism 600 that cooperates therewith. The user can quickly replace the extrusion mechanism 400 of different sizes or shapes, thereby adapting to different liquid flow or flow rate requirements. In addition, since the driving mechanism 600 is directly connected to the limiting mechanism 500, and the limiting mechanism 500 drives the extrusion mechanism 400 to move circumferentially along the limiting seat 300, the extrusion process of the hose 200 is smoother, reducing the jamming and energy loss caused by improper movement of the extrusion mechanism 400. The peristaltic pump of the present invention not only does not need to increase the motor speed when increasing the flow rate, thereby avoiding the increase in energy consumption and wear caused by high-speed operation, but also extends the service life of the peristaltic pump while reducing energy consumption and improving its operational flexibility.

[0044] As an optional embodiment, the housing 100, the squeezing mechanism 400, the limiting mechanism 500 and the driving mechanism 600 are all coaxially arranged, which can simplify the structure of the peristaltic pump, reduce manufacturing costs, and improve the overall stability and operating efficiency of the peristaltic pump.

[0045] As another optional embodiment, the drive mechanism 600 uses a drive motor, whose output shaft extends into the accommodating space 101 and extends from the side of the limiting mechanism 500 away from the limiting seat 300. The drive motor can be directly connected to the limiting mechanism 500, thereby providing direct power transmission, reducing energy loss, and improving transmission efficiency. The connection method between the output shaft of the drive motor and the limiting mechanism 500 is such that when the drive motor is started, it can directly push the limiting mechanism 500 to move along a preset path. The movement of the limiting mechanism 500 then pushes the extrusion mechanism 400 to move circumferentially along the limiting seat 300, thereby achieving extrusion of the hose 200. The peristaltic pump can respond to user operations more quickly.

[0046] Please continue reading Figure 2 and Figure 3 In an embodiment of the present invention, a ring-shaped limiting groove 301 with a notch facing outward is provided on the side of the limiting seat 300 facing the extrusion mechanism 400. The ring-shaped limiting groove 301 extends along the circumference of the limiting seat 300, and one end of the extrusion mechanism 400 is detachably arranged in the ring-shaped limiting groove 301.

[0047] Specifically, the annular retaining groove 301 provided on the retaining seat 300 provides space for the installation of the extrusion mechanism 400. To install the extrusion mechanism 400, simply insert one end of the extrusion mechanism 400 into the annular retaining groove 301 for quick and convenient installation. Furthermore, because the annular retaining groove 301 extends circumferentially along the retaining seat 300, the extrusion mechanism 400, once installed, can be guided by the annular retaining groove 301 to precisely move and position itself along the circumference of the retaining seat 300, thereby ensuring stability and reliability during the extrusion process of the hose 200.

[0048] Furthermore, the extrusion mechanism 400 is detachably connected to the annular retaining groove 301, allowing for quick replacement of the extrusion mechanism 400 based on actual needs. To accommodate a different liquid flow rate or flow rate, the existing extrusion mechanism 400 can be removed from the annular retaining groove 301 and replaced with a new extrusion mechanism 400 of a more suitable size or shape. This simple and efficient replacement process enhances the peristaltic pump's flexibility.

[0049] Please continue reading Figure 3 In an embodiment of the present invention, the extrusion mechanism 400 includes a mounting seat 410 and an extrusion wheel 420. The mounting seat 410 is detachably mounted in the annular limiting groove 301, and the extrusion wheel 420 is rotatably mounted on the mounting seat 410. The extrusion wheel 420 abuts against the hose 200.

[0050] Specifically, the mounting base 410, serving as the supporting component of the extrusion mechanism 400, can be easily inserted into the annular retaining groove 301 of the retaining base 300, enabling quick and reliable installation. Furthermore, because the mounting base 410 and the annular retaining groove 301 are detachably connected, when the extrusion mechanism 400 needs to be maintained or replaced, the mounting base 410 can simply be removed from the annular retaining groove 301. This simple and convenient operation reduces maintenance costs and time.

[0051] The squeezing wheel 420, the actuator of the squeezing mechanism 400, is rotatably mounted on the mounting base 410. Supported by the mounting base 410, the squeezing wheel 420 can flexibly rotate about its own axis. When in contact with the hose 200, the squeezing wheel 420 continuously conveys the liquid within the hose 200 forward through its rolling and squeezing action. This rotational squeezing reduces wear on the hose 200, extending its service life while also improving delivery efficiency and stability.

[0052] Please continue reading Figure 3 , and see Figure 4In an embodiment of the present invention, the mounting base 410 includes a mounting frame 411, a mounting shaft 412 and two insertion rods 413. The mounting frame 411 extends along the axial direction of the limiting seat 300. The extrusion wheel 420 is rotatably mounted on the mounting frame 411 through the mounting shaft 412. The two insertion rods 413 are spaced apart along the extension direction of the annular limiting groove 301. One end of the two insertion rods 413 is connected to the mounting frame 411, and the other ends of the two insertion rods 413 extend into the annular limiting groove 301 and slide with the annular limiting groove 301.

[0053] Specifically, the mounting frame 411 serves as a carrier connecting the extrusion wheel 420 and the insertion rod 413. It extends axially along the limit seat 300 and provides a stable support platform for the installation of the extrusion wheel 420. The extrusion wheel 420 is rotatably mounted on the mounting frame 411 via the mounting shaft 412. This ensures that the extrusion wheel 420 can flexibly rotate about its own axis under the support of the mounting frame 411, thereby achieving the extrusion process of the hose 200.

[0054] Two insertion rods 413 are located on either side of the mounting bracket 411, spaced apart along the extension direction of the annular retaining groove 301. One end of the insertion rod 413 is connected to the mounting bracket 411, while the other end extends into the annular retaining groove 301, forming a sliding engagement therewith. This allows the mounting base 410 to slide and position smoothly within the annular retaining groove 301 with the aid of the insertion rods 413. This also prevents the mounting base 410 from deflecting or falling off during movement, further enhancing the stability and reliability of the extrusion mechanism 400.

[0055] Please continue reading Figure 4 In an embodiment of the present invention, a mounting groove 414 with an outward opening is provided on one side of the mounting frame 411 facing the limiting mechanism 500. The mounting groove 414 is provided corresponding to the position of the limiting mechanism 500 and is used for the limiting mechanism 500 to extend into.

[0056] Specifically, the mounting groove 414 allows the limiting mechanism 500 to be easily inserted therein, which not only simplifies the assembly process, but also ensures the stability of the limiting mechanism 500 during operation, avoids unstable performance due to installation errors, and facilitates the transmission of motion and force.

[0057] The position of the limiting mechanism 500 corresponds to the mounting groove 414, ensuring the correct docking position between the two. When the limiting mechanism 500 extends into the mounting groove 414, it can achieve a snap connection or abutment, which not only ensures the connection stability of the limiting mechanism 500 and the extrusion mechanism 400, but also improves the anti-interference ability of the entire peristaltic pump.

[0058] In addition, due to the precise fit between the limiting mechanism 500 and the mounting slot 414, the motion and force can be effectively transmitted, thereby improving the overall performance and reliability of the device.

[0059] Please continue reading Figure 2 and Figure 3 In an embodiment of the present invention, the limiting mechanism 500 includes a limiting ring 510, a rotating shaft 520, a limiting plate 530 and a support 540. The limiting ring 510 is arranged on one side of the limiting seat 300, the limiting ring 510 is connected to the driving mechanism 600, the support 540 is installed on the outer circumference of the limiting ring 510, the rotating shaft 520 extends along the radial direction of the limiting ring 510, the rotating shaft 520 is installed on the support 540, the limiting plate 530 is arranged between the limiting ring 510 and the extrusion mechanism 400, one end of the limiting ring 510 is rotatably connected to the support 540 through the rotating shaft 520, and the other end of the limiting ring 510 is arranged on one side of the extrusion mechanism 400 corresponding to the position of the extrusion mechanism 400, and the limiting plate 530 can move between a pressing position or a release position close to or away from the limiting seat 300, and correspondingly presses or releases the extrusion mechanism 400 on the limiting seat 300.

[0060] Specifically, the limiting ring 510 is disposed on one side of the limiting seat 300 and is connected to the drive mechanism 600. Driven by the drive mechanism 600, the limiting ring 510 is able to rotate, i.e., rotate on its own, thereby correspondingly driving the extrusion mechanism 400 to move circumferentially along the limiting seat 300. The support 540 is mounted on the outer periphery of the limiting ring 510, providing a stable support platform for the rotating shaft 520. The rotating shaft 520 extends radially along the limiting ring 510 and is mounted on the support 540, allowing the limiting ring 510 to rotate about the rotating shaft 520, thereby improving the flexibility and controllability of the limiting mechanism 500.

[0061] The limiting plate 530 is positioned between the limiting ring 510 and the extrusion mechanism 400, and is perpendicular to the rotating shaft 520. When the limiting ring 510 rotates and the limiting plate 530 is in the abutting position, the limiting plate 530 presses the extrusion mechanism 400 against the limiting seat 300, driving it to squeeze and convey the hose 200. When the limiting plate 530 moves to the releasing position, the extrusion mechanism 400 is released, allowing for easy removal or replacement. This allows for faster and more precise state switching of the extrusion mechanism 400, improving the efficiency and maintainability of the peristaltic pump.

[0062] Please continue reading Figure 3 In an embodiment of the present invention, the limiting mechanism 500 also includes a first elastic member 550, which is arranged close to the extrusion mechanism 400, one end of the first elastic member 550 is connected to the limiting plate 530, and the other end of the first elastic member 550 is connected to the limiting seat 300.

[0063] Specifically, the first elastic member 550 functions to provide a reset force. When the limit plate 530 moves to a release position along the axial direction of the limit seat 300 in a direction away from the extrusion mechanism 400, the first elastic member 550 provides a reset force, allowing the limit plate 530 to automatically return to its initial abutting position. That is, when the limit plate 530 moves to the release position along the axial direction of the limit seat 300 under the action of an external force, the extrusion mechanism 400 is released and can be easily disassembled or replaced. After the extrusion mechanism 400 is replaced, the peristaltic pump can automatically return the limit plate 530 to its initial abutting position, re-pressing the extrusion mechanism 400 against the limit seat 300.

[0064] More specifically, when the limit plate 530 moves to the release position, the first elastic member 550 is stretched, generating a restoring force directed toward the abutting position. Once the external force is removed, the restoring force automatically drives the limit plate 530 back in the opposite direction until the extrusion mechanism 400 is again abutted against the limit seat 300. This not only simplifies the operation of the peristaltic pump and reduces the user's workload, but also improves the efficiency and reliability of the device and avoids errors or failures caused by improper operation.

[0065] Please continue reading Figures 1 to 3 , and see Figure 5 and Figure 6 In an embodiment of the present invention, the housing 100 includes a shell 110, a cover plate 120 and a supporting assembly 700. One side of the shell 110 is recessed inward to form a receiving space 101 with an opening facing outward. The cover plate 120 is detachably covered on the receiving space 101 at a position corresponding to the opening. The supporting assembly 700 is slidably arranged on a side of the cover plate 120 facing the receiving space 101 along the circumference of the cover plate 120. The supporting assembly 700 is arranged at a position corresponding to the limiting mechanism 500 and is used to abut against the side of the limiting mechanism 500 facing away from the extrusion mechanism 400.

[0066] Specifically, the housing 110, the primary peripheral structure of the peristaltic pump, has one side recessed inward to form an outwardly open accommodation space 101. This provides space for installing and securing internal components, facilitating subsequent assembly and maintenance operations. A cover 120 is removably mounted over the open portion of accommodation space 101, providing both sealing and protection. When inspection or maintenance of internal components is required, simply remove cover 120 to conveniently access accommodation space 101, simplifying maintenance procedures and simplifying the process.

[0067] The abutment assembly 700 is slidably disposed along the circumference of the cover plate 120 on the side of the cover plate 120 facing the interior of the accommodating space 101 and is arranged corresponding to the position of the limiting mechanism 500. When the cover plate 120 is in place, the abutment assembly 700 can tightly abut the side of the limiting mechanism 500 facing away from the extrusion mechanism 400, forming a stable and reliable support structure, thereby improving the stability and reliability of the limiting mechanism 500.

[0068] Please continue reading Figure 6 In an embodiment of the present invention, a guide ring 800 is installed on the side of the cover plate 120 facing the accommodating space 101, and an annular guide groove 801 is provided on the side of the guide ring 800 facing away from the cover plate 120, and the abutment assembly 700 is slidably provided in the annular guide groove 801 along the circumference of the cover plate 120.

[0069] Specifically, the guide ring 800 is installed on the side of the cover plate 120 facing the accommodating space 101, so that the guide ring 800 can form a stable support platform on the cover plate 120. The side of the guide ring 800 facing away from the cover plate 120 is provided with an annular guide groove 801 to adapt to the size and shape of the abutment assembly 700.

[0070] The abutment assembly 700 can slide within the annular guide groove 801 along the circumference of the cover plate 120. This allows the abutment assembly 700 to follow the movement of the limiting mechanism 500 on the cover plate 120, while the annular guide groove 801 provides the necessary guidance and restraint, ensuring the stability and accuracy of the abutment assembly 700 during movement. This not only simplifies the assembly and disassembly process of the abutment assembly 700, but also improves the reliability and durability of the peristaltic pump's overall structure, further pressing the limiting mechanism 500 and the extrusion mechanism 400 against the limiting seat 300.

[0071] Please continue reading Figure 6 In an embodiment of the present invention, the abutment assembly 700 includes a slider 710, a guide post 720, a mounting plate 730, a second elastic member 740 and a abutment block 750. The slider 710 is slidably mounted in the annular guide groove 801 along the circumference of the cover plate 120. The mounting plate 730 is mounted on the side of the slider 710 facing the accommodating space 101 through the second elastic member 740. The guide post 720 extends axially along the cover plate 120. One end of the guide post 720 is mounted on the slider 710, and the other end of the guide post 720 extends from the side of the mounting plate 730 away from the slider 710. The abutment block 750 is mounted on the mounting plate 730. The position of the abutment block 750 corresponding to the extrusion mechanism 400 is provided with a slot 751 for accommodating the extrusion mechanism 400.

[0072] Specifically, the slider 710 is slidably installed in the annular guide groove 801 along the circumference of the cover plate 120. The slider 710 moves in the annular guide groove 801 to adjust the position of the abutting component 700 to press against the limiting mechanism 500 at different positions.

[0073] The mounting plate 730 is mounted on the side of the slider 710 facing the receiving space 101 via a second elastic member 740. The second elastic member 740 enables the mounting plate 730 to move or bend appropriately when subjected to an external force (such as pressure from the squeezing mechanism 400), thereby reducing damage to the abutting assembly 700 and the squeezing mechanism 400.

[0074] The guide post 720 extends axially along the cover plate 120, with one end mounted on the slider 710 and the other end extending from the side of the mounting plate 730 facing away from the slider 710. This provides additional support for the abutment assembly 700, ensuring alignment and stability of the entire abutment assembly 700 during operation. The guide post 720 enables the abutment block 750 to remain in the correct position to ensure contact with the extrusion mechanism 400.

[0075] The abutment block 750 is mounted on the mounting plate 730 and has a slot 751 for accommodating the extrusion mechanism 400, located at a position corresponding to the extrusion mechanism 400. The slot 751 matches the shape and size of the extrusion mechanism 400, ensuring that the extrusion mechanism 400 is properly and stably fixed during operation. This reduces vibration and movement during operation, thereby improving the overall efficiency and output quality of the peristaltic pump.

[0076] More specifically, the second elastic member 740 is installed between the slider 710 and the mounting plate 730. Through its elastic deformation ability, the mounting plate 730 can be flexibly moved and adjusted within a certain range. When the size of the extrusion mechanism 400 changes, the second elastic member 740 can automatically adapt and, through its elastic restoring force, always maintain close contact between the mounting plate 730 and the extrusion mechanism 400. It not only ensures the matching accuracy between the abutment assembly 700 and the extrusion mechanism 400, but also provides continuous and stable pressure support for the limiting mechanism 500 and the extrusion mechanism 400. During the operation of the peristaltic pump, the second elastic member 740 can continuously press the limiting mechanism 500 and the extrusion mechanism 400 against the limiting seat 300, ensuring the stable extrusion of the hose 200 by the extrusion mechanism 400, thereby improving the uniformity and reliability of the delivery. At the same time, this pressing effect also effectively reduces vibration and noise during operation, extending the service life of the equipment.
