Description

Technical Field

[0001] This utility model relates to the field of fluid transport technology, specifically to a motor-driven fluid transport device. Background Technology

[0002] In chemical analysis, biological experiments, drug development, and materials science, the dynamic flexibility of fluid transport has become a core element determining the reliability and innovation of experimental results.

[0003] In existing technologies, the piston stroke of a traditional pump is preset by the mechanical structure. For example, the syringe capacity of a syringe pump is fixed. If the flow rate is changed according to different working requirements, the hardware needs to be changed manually, such as changing to a syringe of different specifications. This is cumbersome and prone to introducing errors. In gradient elution experiments, traditional syringe pumps need to be combined with multiple devices to achieve flow rate changes, which is costly and takes up a lot of space.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a motor fluid conveying device, including a mounting housing 1. A flow control component is installed inside the mounting housing 1. The flow control component includes a drive motor 2 mounted on the inner wall of the mounting housing 1. The bottom end of the drive motor 2 is fixedly connected to the inner wall of the mounting housing 1. The drive motor 2 serves as the basic power source for the flow control component. The output end of the drive motor 2 is connected to a first transmission wheel 3. When the drive motor 2 starts and rotates, it synchronously drives the first transmission wheel 3 to rotate. A transmission belt 4 is fitted onto the outer wall of the first transmission wheel 3. The first transmission wheel 3 is connected to a second transmission wheel 5 via the transmission belt 4. The second transmission wheel 5 receives the rotation of the first transmission wheel 3 via the transmission belt 4. One side of the outer wall of the second transmission wheel 5 is fixed. A turntable 6 is connected, and the turntable 6 is fixedly connected to the second transmission wheel 5. When the second transmission wheel 5 rotates, the turntable 6 rotates synchronously. A threaded rod 7 is rotatably connected to one side of the outer wall of the turntable 6. A first moving block 8 is threadedly connected to the outer wall of the threaded rod 7. A connecting rod 9 is rotatably connected to one side of the outer wall of the first moving block 8. The rotation of the threaded rod 7 drives the first moving block 8 to move linearly along the axial direction, changing the push-pull distance of the connecting rod 9, thereby changing the push-out distance of the connecting rod 9. A second moving block 10 is rotatably connected to the end of the connecting rod 9 away from the first moving block 8. A piston rod 11 is fixedly connected to one side of the outer wall of the second moving block 10. Under the drive of the first moving block 8, the second moving block 10 moves linearly along the guide frame 12, and drives the piston rod 11 to move.

[0023] participate Figure 2 , Figure 3 A guide frame 12 is installed on the inner wall of one side of the housing 1. The inner wall of the second moving block 10 is slidably connected to the top two sides of the guide frame 12. The guide frame 12 prevents the second moving block 10 from deflecting due to the thrust of the connecting rod 9, thus ensuring the accuracy of the piston rod 11's movement.

[0024] See Figure 1 A sleeve 13 is slidably connected to the outer wall of the piston rod 11. Both the top and bottom ends of the sleeve 13 are connected to pipes 14. A valve is installed at the end of each pipe 14 near the sleeve 13. The valve of the top pipe 14 opens during the discharge phase, and the valve of the bottom pipe 14 opens during the suction phase to ensure unidirectional fluid flow. When the valve is closed, it is used to withstand fluid pressure and prevent pressure fluctuations caused by backflow.

[0025] See Figure 1 The bottom end of the sleeve 13 is connected to the bracket 15, which is fixedly connected to the mounting plane to enhance the stability of the sleeve 13. A control panel 16 is installed on one side of the outer wall of the mounting housing 1. Multiple control buttons are installed on the surface of the control panel 16. The control panel 16 can start, stop or adjust the drive motor 2 through the control buttons to improve the response speed of the component to the operator.

[0026] See Figure 1 The top of the mounting housing 1 is connected to a door 17, which is made of transparent material. A hinge is installed on one side of the bottom of the door 17. The door 17 is rotatably connected to the mounting housing 1 via the hinge. The transparent door 17 allows staff to observe the working status of the components from the outside, monitor them in real time, or make adjustments later.

[0027] Working principle: After the drive motor 2 starts, it drives the first transmission wheel 3 to rotate. The first transmission wheel 3 transmits power to the second transmission wheel 5 through the transmission belt 4. The second transmission wheel 5 drives the turntable 6 to rotate. The rotation of the turntable 6 synchronously drives the connecting rod 9 to reciprocate. The connecting rod 9 then drives the second moving block 10 to reciprocate. Because the inner wall of the second moving block 10 is slidably connected to the guide frame 12, the second moving block 10 will reciprocate linearly along the guide frame 12, thereby realizing the reciprocating motion of the piston rod 11 in the sleeve 13, pushing the fluid through the pipe 14 and the valve for delivery. When it is necessary to adjust the flow rate, by rotating the threaded rod 7, the first moving block 8 moves linearly along the axial direction of the threaded rod 7. At the same time, the guide rail on the turntable 6 keeps the movement of the first moving block 8 stable, realizing the adjustment of the distance that the connecting rod 9 drives the second moving block 10 to push out, thereby changing the distance of the piston rod 11 reciprocating in the sleeve 13, and achieving the adjustment effect.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
