Description

Technical Field

[0001] This invention relates to the field of peristaltic pump technology, specifically a peristaltic pump with flow regulation function. Background Technology

[0002] A peristaltic pump is a device that delivers fluid by squeezing and releasing a flexible hose. It consists of three parts: a driver, a pump head, and a hose. The hose is usually made of wear-resistant and corrosion-resistant materials, such as rubber, silicone, or polyurethane. The working principle of a peristaltic pump is that a rotating roller (or rotor) squeezes the hose to form a closed chamber, thereby propelling the fluid forward. Peristaltic pumps have many advantages, including self-priming capability, bidirectional delivery, ability to handle fluids containing air bubbles and particles, and simple structure and easy maintenance.

[0003] Current peristaltic pumps typically regulate the flow rate of liquid by adjusting the motor speed. As the motor speed decreases, the negative pressure inside the hose also decreases. When the negative pressure inside the hose is insufficient, the suction of liquid from the hose may become intermittent, thus affecting the working efficiency of the peristaltic pump.

[0017] The present invention has the following beneficial effects:

[0018] This invention involves attaching a flexible hose to the surface of a connecting component. After placing the inlet pipe into the liquid, the motor is activated to drive the pump head to rotate. The negative pressure generated by the pump head squeezing the hose is transmitted to the inside of the inlet pipe through the connecting component. The inlet pipe can then use this negative pressure to extract the liquid. When it is necessary to adjust the flow rate of the hose, the electric actuator is activated to push the lifting frame upward. The end of the lifting frame slides on the surface of the sliding plate, which limits the lifting frame and improves the stability of the lifting frame supporting the conical sealing block. As the lifting frame moves, it pushes the conical sealing block upward via a sliding rod. The conical sealing block separates from the inner wall of the vertical pipe during movement. The flow rate in the hose is adjusted by the distance between the conical sealing block and the vertical pipe, improving the convenience of flow rate adjustment in the hose and eliminating the need to adjust the motor speed to avoid affecting the negative pressure in the hose.

[0019] This invention requires that when the hose is fitted onto the surface of the insertion tube, the screw ring is twisted and rotated on the surface of the insertion tube. When the screw ring moves, it pushes the force rod into the interior of the insertion tube through the bending frame. When the force rod moves, it pushes the conical block to separate from the interior of the insertion tube, so that the insertion tube can be linked with the cylindrical tube to complete the extraction operation. After the conical block separates from the inner wall of the insertion tube, the hose can be fitted onto the surface of the screw ring to complete the connection. The screw ring is used to limit the hose, improve the stability of the hose during operation, and prevent the hose from slipping when the pump head squeezes the hose. Two insertion tubes are provided on the surface of the cylindrical tube, so that the two ends of the hose are inserted into the surface of the screw ring for alternating extraction operations.

[0020] When the screw hole ring of this invention moves, it pushes the triangular plate to deform through the connection between the positioning ring and the connecting rod. At this time, the top of the triangular plate will push the sliding hole frame to move upward. When the sliding hole frame moves upward, it will push the circular groove block to move upward through the round rod. When the circular groove block moves upward, it will cooperate with the circular hole plate to squeeze the hose, further improving the stability of the hose during operation. At the same time, the circular hole plate will limit the hose through the disc to prevent the hose from sliding when the pump head squeezes the hose.

[0021] This invention features a perforated plate inside the water inlet frame to filter the liquid, preventing impurities from entering the hose and causing blockage. When the pump head rotates, it pushes a cross-shaped rod to rotate inside the mounting frame via a contact block. As the rod rotates, it presses a semi-circular contact plate against a semi-circular block. This pressure causes the contact plate to move downwards via a sliding frame. The downward movement of the connecting rod then pushes a pressure plate via a cross-shaped mechanism. The pressure plate, in turn, uses the elasticity of a spring to push a cleaning rod to clean the bottom of the perforated plate, preventing impurities from accumulating on its surface and affecting water intake. Simultaneously, as the cross-shaped mechanism rotates, it pushes a ball against the inner wall of a circular ring via a spring rod, generating vibration. This vibration is transmitted through the circular ring to the surface of the perforated plate, further improving the cleaning effect.

[0022] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-8 As shown, the present invention is a peristaltic pump with flow regulation function, including a motor 1, a bracket 2 fixedly connected to the end of the motor 1, a support leg 3 fixedly connected to the bottom of the bracket 2, an end cap 4 provided at the end of the bracket 2 away from the motor 1, the end cap 4 being connected to the bracket 2 by a screw, a positioning groove 8 being provided at the end of the bracket 2 away from the motor 1, a pump head 6 being rotatably connected to the inner wall of the positioning groove 8, the pump head 6 being fixedly connected to the output end of the motor 1, a flexible hose 7 being provided inside the positioning groove 8, a protective frame 5 being fixedly connected at the end of the end cap 4 away from the bracket 2, and an adjustment component 12 being provided at the bottom of the protective frame 5;

[0036] The adjusting component 12 includes a fixed rod 20, a sliding plate 22 fixedly connected to the end of the fixed rod 20, a lifting frame 28 slidably connected to the surface of the sliding plate 22, an electric push rod 21 fixedly connected to the top of the lifting frame 28, the top of the electric push rod 21 fixedly connected to the bottom of the fixed rod 20, a sliding rod 23 fixedly connected to the bottom of the lifting frame 28, a conical sealing block 26 fixedly connected to the bottom of the sliding rod 23, a cylindrical tube 24 connected to the bottom of the protective frame 5, a vertical tube 25 connected to the bottom of the cylindrical tube 24, and a circular hole plate 27 fixedly connected to the inner wall of the cylindrical tube 24.

[0037] A water inlet frame 9 is fixedly connected to the surface of the cylindrical tube 24. A connecting frame 10 is threadedly connected to the bottom of the water inlet frame 9. A water inlet pipe 11 is connected to the bottom of the connecting frame 10. A connecting component 13 is provided on the surface of the cylindrical tube 24. An anti-clogging component 15 is provided inside the water inlet frame 9. A stabilizing component 14 is provided at the end of the bracket 2.

[0038] The surface of the pump head 6 contacts the surface of the hose 7, and the end of the hose 7 extends to the outer end of the positioning groove 8. There are two slide plates 22, which are symmetrically arranged with the fixing rod 20 as the center.

[0039] The ends of the two sliding plates 22 away from the fixed rod 20 are fixedly connected to the inner wall of the protective frame 5 and the surface of the end cap 4, respectively. The lifting frame 28 is located inside the protective frame 5. After the hose 7 is sleeved on the surface of the connecting component 13, the water inlet pipe 11 is placed inside the liquid and the motor 1 is started to drive the pump head 6 to rotate. When the pump head 6 rotates, the negative pressure generated by squeezing the hose 7 will be transmitted to the inside of the water inlet pipe 11 through the connecting component 13. The water inlet pipe 11 can then use the negative pressure to extract the liquid. When it is necessary to adjust the water output of the hose 7, the electric actuator 21 is activated to push the lifting frame 28 upward. The end of the lifting frame 28 will slide on the surface of the sliding plate 22. The lifting frame 28 is limited by the sliding plate 22, thereby improving the stability of the lifting frame 28 in supporting the conical sealing block 26. When the lifting frame 28 moves, it pushes the conical sealing block 26 upward through the sliding rod 23. When the conical sealing block 26 moves, it will separate from the inner wall of the vertical tube 25. The flow rate in the hose 7 is adjusted by the distance between the conical sealing block 26 and the vertical tube 25, which improves the convenience of adjusting the flow rate in the hose 7. It is not necessary to adjust the speed of the motor 1 to avoid affecting the negative pressure in the hose 7. The surface of the sliding rod 23 is slidably connected to the inner wall of the circular plate 27, and the lower surface of the conical sealing block 26 is in contact with the inner wall of the vertical tube 25.

[0040] The connecting component 13 includes a rectangular frame 31, the end of which is in communication with the surface of the cylindrical tube 24. The end of the rectangular frame 31 away from the cylindrical tube 24 is connected to a plug tube 30. The surface of the plug tube 30 is threaded with a threaded hole ring 36. The surface of the threaded hole ring 36 is rotatably connected with a positioning ring 39. The end of the threaded hole ring 36 is provided with an annular groove 35. The inner wall of the rectangular frame 31 is fixedly connected with a through hole frame 38. The surface of the through hole frame 38 is fixedly connected with a spring rod 37. The end of the spring rod 37 away from the through hole frame 38 is fixedly connected with a conical block 32. The end of the conical block 32 away from the spring rod 37 is fixedly connected with a force-bearing rod 33. The end of the force-bearing rod 33 away from the conical block 32 is fixedly connected with a bending frame 34. The end of the bending frame 34 away from the force-bearing rod 33 is slidably connected to the inner wall of the annular groove 35.

[0041] The end of the conical block 32 away from the elastic rod 37 contacts the inner wall of the insertion tube 30, and the end of the force rod 33 away from the conical block 32 extends to the outer end of the insertion tube 30. When the flexible tube 7 needs to be fitted onto the surface of the insertion tube 30, the screw ring 36 is twisted to rotate on the surface of the insertion tube 30. As the screw ring 36 moves, it pushes the force rod 33 towards the interior of the insertion tube 30 via the bending frame 34. As the force rod 33 moves, it pushes the conical block 32 to separate from the interior of the insertion tube 30, thus allowing the insertion tube 30 to work in conjunction with the cylindrical tube 24 to complete the extraction operation. After the cone block 32 separates from the inner wall of the insertion tube 30, the hose 7 can be fitted onto the surface of the screw hole ring 36 to complete the connection. The screw hole ring 36 is used to limit the hose 7, improve the stability of the hose 7 during operation, and prevent the hose 7 from sliding when the pump head 6 squeezes the hose 7. Two insertion tubes 30 are provided on the surface of the cylindrical tube 24, so that the two ends of the hose 7 are inserted into the surface of the screw hole ring 36 for alternating extraction operations. The end of the bending frame 34 away from the cone block 32 extends to the top of the insertion tube 30, and the surface of the screw hole ring 36 is adapted to the inner wall of the hose 7.

[0042] The stabilizing component 14 includes a connecting rod 44, the end of which is fixedly connected to the lower surface of the positioning ring 39. A triangular plate 43 is rotatably connected to the end of the connecting rod 44 away from the positioning ring 39. A sliding hole frame 42 is hinged to the center of the triangular plate 43. A round rod 45 is slidably connected to the inner wall of the sliding hole frame 42. A round groove block 48 is fixedly connected to the end of the round rod 45. A stabilizing frame 47 is fixedly connected to the top of the round groove block 48. A limiting plate 40 is fixedly connected to the end of the bracket 2. A round hole plate 41 is fixedly connected to the lower surface of the limiting plate 40. Rubber pads 49 are fixedly connected to the inner walls of the round groove block 48 and the round hole plate 41, respectively. A disc 46 is fixedly connected to the surface of the hose 7.

[0043] The end of the stabilizing frame 47 away from the circular groove block 48 is slidably connected to the surface of the limiting plate 40. The hose 7 is located above the circular groove block 48 and below the circular hole plate 41. When the screw hole ring 36 moves, it pushes the triangular plate 43 to deform through the connection between the positioning ring 39 and the connecting rod 44. At this time, the top of the triangular plate 43 will push the sliding hole frame 42 to move upward. When the sliding hole frame 42 moves upward, it pushes the circular groove block 48 to move upward through the round rod 45. When the circular groove block 48 moves upward, it will cooperate with the circular hole plate 41 to squeeze the hose 7, further improving the stability of the hose 7 during operation. At the same time, the circular hole plate 41 will limit the hose 7 through the disc 46 to prevent the hose 7 from sliding when the pump head 6 squeezes the hose 7. The disc 46 is located at the end where the circular groove block 48 and the circular hole plate 41 are close to each other. The surface of the hose 7 is in contact with the inner wall of the rubber pad 49.

[0044] The anti-clogging component 15 includes a rotating rod 50, the end of which is fixedly connected to the surface of the pump head 6. A contact block 58 is fixedly connected to the surface of the rotating rod 50. A mounting bracket 52 is fixedly connected to the surface of the end cover 4. A cross-hole rod 51 is rotatably connected to the inner wall of the mounting bracket 52. A semi-circular block 53 is fixedly connected to the end of the cross-hole rod 51. A spring 57 is fixedly connected to the bottom of the fixing rod 20. A sliding frame 55 is fixedly connected to the bottom of the spring 57. A semi-circular contact plate 54 is fixedly connected to the top of the sliding frame 55. A linkage rod 56 is fixedly connected to the bottom of the 5. A screen plate 59 is fixedly connected to the inner wall of the water inlet frame 9. A cross 64 is fixedly connected to the bottom of the screen plate 59. A pressure plate 62 is hinged to the end of the cross 64. A cleaning rod 66 is fixedly connected to the end of the pressure plate 62 away from the cross 64. The pressure plate 62 and the cross 64 are hinged by a spring piece 61. A round hole ring 60 is fixedly connected to the bottom of the screen plate 59. A spring rod 63 is fixedly connected to the top of the cross 64. A ball 65 is fixedly connected to the top of the spring rod 63.

[0045] The surface of the contact block 58 contacts the inner wall of the cross-hole rod 51. The top of the sliding frame 55 extends above the fixed rod 20. The bottom of the semi-circular block 53 contacts the top of the semi-circular contact plate 54. The present invention provides a perforated plate 59 inside the water inlet frame 9 to filter the liquid, preventing impurities in the liquid from entering the hose 7 and causing blockage. When the pump head 6 rotates, it pushes the cross-hole rod 51 to rotate inside the mounting frame 52 via the contact block 58. When the cross-hole rod 51 rotates, it squeezes the semi-circular contact plate 54 via the semi-circular block 53. After being squeezed, the semi-circular contact plate 54 pushes the connecting rod 56 downward via the sliding frame 55. When the connecting rod 56 moves downward, it passes through the cross-hole rod 54... The frame 64 pushes the pressure plate 62 to move. When the pressure plate 62 moves, the elasticity of the spring 61 pushes the cleaning rod 66 to clean the bottom of the screen plate 59, so as to avoid the accumulation of impurities on the surface of the screen plate 59 and affect the water intake effect. At the same time, when the cross 64 rotates, it pushes the ball 65 to impact the inner wall of the circular hole ring 60 through the spring rod 63 and generates vibration. The vibration will be transmitted to the surface of the screen plate 59 through the circular hole ring 60, further improving the cleaning effect of the screen plate 59. The bottom of the linkage rod 56 passes through the conical sealing block 26 and extends to the bottom of the screen plate 59. The end of the pressure plate 62 away from the cross 64 is inclined towards the end of the screen plate 59, and the surface of the cleaning rod 66 contacts the bottom of the screen plate 59.

[0046] In use, after fitting the hose 7 onto the surface of the connecting component 13, the inlet pipe 11 is placed inside the liquid. The motor 1 is then started to drive the pump head 6 to rotate. The negative pressure generated by the pump head 6 squeezing the hose 7 is transmitted through the connecting component 13 to the inside of the inlet pipe 11, allowing the inlet pipe 11 to draw out the liquid using this negative pressure. To adjust the flow rate of the hose 7, the electric actuator 21 is activated to push the lifting frame 28 upwards. The end of the lifting frame 28 slides on the surface of the sliding plate 22, which limits the lifting frame 28, thereby improving the stability of the lifting frame 28 in supporting the conical sealing block 26. As the lifting frame 28 moves, it pushes the conical sealing block 26 upwards via the sliding rod 23. During this movement, the conical sealing block 26 interacts with the vertical pipe 25. The inner wall of the tube is separated, and the flow rate in the hose 7 is adjusted by the distance between the conical sealing block 26 and the vertical tube 25, which improves the convenience of flow rate adjustment in the hose 7. It is not necessary to adjust the speed of the motor 1 to avoid affecting the negative pressure in the hose 7. When the hose 7 needs to be sleeved on the surface of the insertion tube 30, the screw hole ring 36 is twisted to rotate on the surface of the insertion tube 30. When the screw hole ring 36 moves, it pushes the force rod 33 into the interior of the insertion tube 30 through the bending frame 34. When the force rod 33 moves, it pushes the conical block 32 to separate from the interior of the insertion tube 30, so that the insertion tube 30 can be linked with the cylindrical tube 24 to complete the extraction operation. When the conical block 32 separates from the inner wall of the insertion tube 30, the hose 7 can be sleeved on the surface of the screw hole ring 36 to complete the connection. The threaded ring 36 is used to limit the hose 7, improving its stability during operation and preventing slippage when the pump head 6 squeezes the hose 7. Two insertion pipes 30 are provided on the surface of the cylindrical tube 24, allowing the two ends of the hose 7 to be inserted into the surface of the threaded ring 36 for alternating extraction. When the threaded ring 36 moves, it pushes the triangular plate 43 to deform through the connection between the positioning ring 39 and the connecting rod 44. At this time, the top of the triangular plate 43 pushes the sliding frame 42 upward. When the sliding frame 42 moves upward, it pushes the circular groove block 48 upward through the round rod 45. When the circular groove block 48 moves upward, it cooperates with the circular hole plate 41 to squeeze the hose 7, further improving the stability of the hose 7 during operation. At the same time, the circular hole plate 41 will squeeze the hose 7 through the disc 46. The hose 7 is limited to prevent it from slipping when the pump head 6 squeezes it. A perforated plate 59 is installed inside the water inlet frame 9 to filter the liquid, preventing impurities from entering the hose 7 and causing blockage. When the pump head 6 rotates, it pushes the cross-hole rod 51 to rotate inside the mounting frame 52 via the contact block 58. As the cross-hole rod 51 rotates, it squeezes the semi-circular contact plate 54 via the semi-circular block 53. After being squeezed, the semi-circular contact plate 54 pushes the connecting rod 56 downwards via the sliding frame 55. When the connecting rod 56 moves downwards, it pushes the pressure plate 62 to move via the cross 64. As the pressure plate 62 moves, the elasticity of the spring plate 61 pushes the cleaning rod 66 to clean the bottom of the perforated plate 59.To prevent impurities from accumulating on the surface of the perforated plate 59 and affecting water intake, the cross 64, when rotating, pushes the ball 65 via the spring rod 63 to impact the inner wall of the circular ring 60, generating vibration. This vibration is transmitted through the circular ring 60 to the surface of the perforated plate 59, further improving the cleaning effect on the perforated plate 59.
