[0033] A peristaltic pump is a pump that delivers liquids through the peristaltic principle. It is mainly composed of a motor, a pump head, and a hose. There are multiple rollers, or extrusion wheels, in the pump head. The extrusion wheels squeeze the hose in a certain order, squeezing the liquid in the hose, thereby achieving directional delivery of the liquid.

[0034] However, conventional 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, and the receiving space 101 contains a hose 200 and a limiting seat 300, and the hose 200 extends along the circumferential direction of the limiting seat 300; one end of the extrusion mechanism 400 is detachably disposed on the limiting seat 300, and the other end of the extrusion mechanism 400 abuts against the hose 200; the limiting mechanism 500 is contained 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 releasing position close to or away from the limiting seat 300, and correspondingly presses or releases the extrusion mechanism 400 on 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 along the circumferential direction of 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 driving mechanism 600. An accommodating space 101 is provided in the housing 100, and a hose 200 and a limiting seat 300 are accommodated in the space. The hose 200 extends along the circumference of the limiting seat 300, so that the hose 200 can remain stable during the extrusion by the extrusion mechanism 400, thereby ensuring the delivery efficiency and accuracy of the peristaltic pump.

[0038] One end of the squeezing mechanism 400 is detachably disposed on the limiting seat 300, so that the squeezing mechanism 400 can replace squeezing wheels 420 of different sizes or shapes according to different delivery requirements, thereby adapting to different liquid flow or flow rate requirements. The other end of the squeezing mechanism 400 abuts against the hose 200, and pushes the liquid in the hose 200 forward through physical squeezing.

[0039] The limiting mechanism 500 is accommodated in the accommodating space 101, and 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 close position or a release position close to or far from the limiting seat 300, so that the extrusion mechanism 400 can be quickly disassembled and switched, which increases the adaptability of the peristaltic pump to different usage requirements, and the operation is simple and efficient.

[0040] The driving mechanism 600 is disposed on the housing 100, connected to the limiting mechanism 500, and is used to drive the limiting mechanism 500 to drive the extrusion mechanism 400 to move along the circumferential direction of the limiting seat 300 when the limiting mechanism 500 is pressed 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 extrusion mechanisms 400 of different sizes and at 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 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 matched therewith. It allows the user to quickly replace the extrusion mechanism 400 of different sizes or shapes, so as to adapt 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 more stable, and the jamming and energy loss caused by improper movement of the extrusion mechanism 400 are reduced. The peristaltic pump of the present invention not only does not need to increase the motor speed when increasing the flow rate, avoiding the increase in energy consumption and wear caused by high-speed operation, but also reduces energy consumption while extending the service life of the peristaltic pump 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 the manufacturing cost, 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 allows the limiting mechanism 500 to be directly pushed to move along a preset path when the drive motor is started. 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 the user's operation more quickly.

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

[0047] Specifically, the annular limiting groove 301 provided on the limiting seat 300 provides an accommodating space for the installation of the extrusion mechanism 400. When the extrusion mechanism 400 needs to be installed, only one end of the extrusion mechanism 400 needs to be inserted into the annular limiting groove 301, so that the installation can be realized quickly and conveniently. At the same time, since the annular limiting groove 301 extends along the circumference of the limiting seat 300, the extrusion mechanism 400 can be accurately moved and positioned along the circumference of the limiting seat 300 after installation with the help of the guiding effect of the annular limiting groove 301, thereby ensuring the stability and reliability of the extrusion process of the hose 200.

[0048] In addition, the extrusion mechanism 400 and the annular limiting groove 301 are detachably connected, so that the extrusion mechanism 400 can be quickly replaced according to actual needs. When it is necessary to adapt to different liquid flow rates or flow rates, it is only necessary to remove the original extrusion mechanism 400 from the annular limiting groove 301, and then insert the extrusion mechanism 400 of a more suitable size or shape into the annular limiting groove 301. The entire replacement process is simple and efficient, which improves the flexibility of the peristaltic pump.

[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 . The extrusion wheel 420 is rotatably mounted on the mounting seat 410 , and the extrusion wheel 420 abuts against the hose 200 .

[0050] Specifically, the mounting seat 410, as a bearing component of the extrusion mechanism 400, can be easily inserted into the annular limiting groove 301 of the limiting seat 300 to achieve fast and reliable installation. At the same time, since the mounting seat 410 and the annular limiting groove 301 are connected in a detachable manner, when the extrusion mechanism 400 needs to be maintained or replaced, it is only necessary to remove the mounting seat 410 from the annular limiting groove 301, which is simple and convenient to operate, reducing maintenance costs and time.

[0051] The squeezing wheel 420, as the actuator of the squeezing mechanism 400, can be rotatably mounted on the mounting seat 410. The squeezing wheel 420 can flexibly rotate around its own axis under the support of the mounting seat 410, so that when it abuts against the hose 200, the liquid in the hose 200 is continuously transported forward through its own rolling squeezing effect. Rotational squeezing can reduce the wear of the hose 200, extend the service life of the hose 200, and also improve the transportation efficiency and stability.

[0052] Please continue reading Figure 3 , and see Figure 4In an embodiment of the present invention, the mounting seat 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 arranged at intervals 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, as a carrier connecting the extrusion wheel 420 and the insertion rod 413, extends along the axial direction of the limiting 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 through the mounting shaft 412, ensuring that the extrusion wheel 420 can flexibly rotate around its own axis under the support of the mounting frame 411, thereby realizing the extrusion process of the hose 200.

[0054] The two insertion rods 413 are respectively located on both sides of the mounting frame 411 and are spaced apart along the extension direction of the annular limiting groove 301. One end of the insertion rod 413 is connected to the mounting frame 411, and the other end extends into the annular limiting groove 301 and forms a sliding fit with the annular limiting groove 301. The mounting seat 410 can slide and position smoothly in the annular limiting groove 301 with the help of the insertion rod 413, and at the same time, the mounting seat 410 is prevented from deflecting or falling off during the movement, thereby further improving the stability and reliability of the operation of the extrusion mechanism 400.

[0055] Please continue reading Figure 4 In the 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 therein.

[0056] Specifically, the mounting groove 414 allows the limiting mechanism 500 to be conveniently 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 be clamped or abutted, which not only ensures the connection stability between 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 cooperation between the limiting mechanism 500 and the mounting groove 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 periphery 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 releasing 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 arranged on one side of the limiting seat 300 and is connected to the driving mechanism 600. The limiting ring 510 can rotate, i.e., self-rotate, under the drive of the driving mechanism 600, thereby correspondingly driving the extrusion mechanism 400 to move along the circumferential direction of the limiting seat 300. The support 540 is installed on the outer periphery of the limiting ring 510, providing a stable support platform for the rotating shaft 520. The rotating shaft 520 extends along the radial direction of the limiting ring 510 and is installed on the support 540, so that the limiting ring 510 can rotate around the rotating shaft 520, thereby improving the flexibility and controllability of the limiting mechanism 500.

[0061] The limiting plate 530 is disposed between the limiting ring 510 and the extrusion mechanism 400, and the limiting plate 530 and the rotating shaft 520 are perpendicular to each other. When the limiting ring 510 rotates and when the limiting plate 530 is in the abutting position, the limiting plate 530 can abut the extrusion mechanism 400 against the limiting seat 300, and drive it to extrude and transport the hose 200; and when the limiting plate 530 moves to the release position, the extrusion mechanism 400 is released and can be easily disassembled or replaced. The state switching of the extrusion mechanism 400 is made faster and more accurate, thereby improving the working 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 function of the first elastic member 550 is to provide a reset force. When the limit plate 530 moves to the release position along the axial direction of the limit seat 300 in the direction away from the extrusion mechanism 400, the first elastic member 550 can provide a reset function, so that the limit plate 530 can automatically return to the initial tight 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 to the initial tight position of the limit plate 530, and the extrusion mechanism 400 is pressed against the limit seat 300 again.

[0064] More specifically, when the limit plate 530 moves to the release position, the first elastic member 550 is stretched, generating a reset force pointing to the abutting position. Once the external force is removed, the reset force will drive the limit plate 530 to automatically return in the opposite direction until the extrusion mechanism 400 is abutted against the limit seat 300 again. This not only simplifies the operation steps of the peristaltic pump and reduces the workload of the user, but also improves the working efficiency and reliability of the equipment, and avoids errors or failures caused by improper human 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 abutment assembly 700. One side of the shell 110 is recessed inward to form a receiving space 101 that is open outward. The cover plate 120 is detachably covered on the receiving space 101 at a position corresponding to the opening. The abutment 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 abutment assembly 700 is arranged at a position corresponding to the limiting mechanism 500 and is used to abut against a side of the limiting mechanism 500 that is away from the extrusion mechanism 400.

[0066] Specifically, the housing 110 is the main peripheral structure of the peristaltic pump, and one side of the housing 110 is recessed inward to form an open storage space 101. It provides space for the internal components to be installed and fixed, and also facilitates subsequent assembly and maintenance operations. The cover plate 120 is detachably covered on the open portion of the storage space 101 to play a role in sealing and protection. When it is necessary to inspect or repair the internal components, it is only necessary to remove the cover plate 120 to easily enter the storage space 101, which simplifies the maintenance steps and difficulty.

[0067] The abutting assembly 700 is slidably disposed on the side of the cover plate 120 facing the accommodating space 101 along the circumferential direction of the cover plate 120, and is arranged corresponding to the position of the limiting mechanism 500. When the cover plate 120 is covered in place, the abutting assembly 700 can be closely abutted against the side of the limiting mechanism 500 away from the extrusion mechanism 400, forming a stable and reliable supporting 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 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 receiving 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 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 abutting assembly 700 can slide in the annular guide groove 801 along the circumference of the cover plate 120. The abutting assembly 700 can move on the cover plate 120 following the limiting mechanism 500, and the annular guide groove 801 provides necessary guidance and restriction to ensure the stability and accuracy of the abutting assembly 700 during movement. This not only simplifies the assembly and disassembly process of the abutting assembly 700, but also improves the reliability and durability of the overall structure of the peristaltic pump, and further presses 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 column 720, a mounting plate 730, a second elastic member 740 and an 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 column 720 extends along the axial direction of the cover plate 120. One end of the guide column 720 is mounted on the slider 710, and the other end of the guide column 720 extends out from the side of the mounting plate 730 away from the slider 710. The abutment block 750 is mounted on the mounting plate 730. A slot 751 for accommodating the extrusion mechanism 400 is provided at the position of the abutment block 750 corresponding to 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 , and the slider 710 moves in the annular guide groove 801 , thereby adjusting the position of the abutting assembly 700 to abut 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 through the second elastic member 740. The second elastic member 740 enables the mounting plate 730 to move or bend appropriately when subjected to external force (such as pressure from the extrusion mechanism 400), thereby reducing damage to the abutment assembly 700 and the extrusion mechanism 400.

[0074] The guide post 720 extends along the axial direction of 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 away from the slider 710, providing additional support for the abutment assembly 700 and ensuring the 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 the contact position with the extrusion mechanism 400.

[0075] The abutment block 750 is mounted on the mounting plate 730, and a slot 751 for accommodating the extrusion mechanism 400 is provided 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 correctly and stably fixed during operation. Vibration and movement during operation are reduced, 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, and 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 the close contact between the mounting plate 730 and the extrusion mechanism 400. Not only does it ensure the matching accuracy between the abutment component 700 and the extrusion mechanism 400, but it 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 on the limiting seat 300, ensuring the stable extrusion of the hose 200 by the extrusion mechanism 400, and improving the uniformity and reliability of the delivery. At the same time, this pressing effect also effectively reduces the vibration and noise during work and prolongs the service life of the equipment.
