Abstract
Description
Technical Field
[0001] The invention relates to the technical field of peristaltic pumps, in particular to a peristaltic pump with a flow regulating function. Background Art
[0002] A peristaltic pump is a device that delivers fluid by squeezing and releasing an elastic hose. It consists of 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 to squeeze the hose through a rotating roller (or rotor) to form a closed chamber, thereby pushing the fluid forward. Peristaltic pumps have many advantages, including self-priming ability, bidirectional delivery, the ability to handle fluids containing bubbles and particles, and simple structure and easy maintenance. The current peristaltic pump generally adjusts the flow rate of the liquid by adjusting the speed of the motor. As the motor speed decreases, the negative pressure inside the hose will also decrease. When the negative pressure inside the hose is insufficient, it is easy to cause the hose to extract the liquid intermittently, thereby affecting the working efficiency of the peristaltic pump.

[0013] The present invention has the following beneficial effects: The present invention sleeves the hose on the surface of the connecting component, places the water inlet pipe into the liquid, and then starts the motor to drive the pump head to rotate. The negative pressure generated by squeezing the hose when the pump head rotates will be transmitted to the inside of the water inlet pipe through the connecting component, and the water inlet pipe can use the negative pressure to extract the liquid. When the water output of the hose needs to be adjusted, the electric push rod is started to push the lifting frame to move upward, and the end of the lifting frame will slide on the surface of the slide plate. The slide plate is used to limit the lifting frame, thereby improving the stability of the lifting frame supporting the conical sealing block. When moving, the lifting frame pushes the conical sealing block upward by the sliding rod, and the conical sealing block is separated from the inner wall of the vertical pipe when moving. The flow in the hose is adjusted by the distance between the conical sealing block and the vertical pipe, thereby improving the convenience of adjusting the flow in the hose, and there is no need to adjust the speed of the motor to avoid affecting the negative pressure in the hose.
[0014] The present invention requires that when the hose is sleeved on the surface of the plug-in tube, the screw hole ring is twisted to rotate on the surface of the plug-in tube, and the screw hole ring pushes the force-bearing rod to move toward the inside of the plug-in tube through the bent frame when moving, and the force-bearing rod pushes the conical block to separate from the inside of the plug-in tube when moving, so that the plug-in tube can be linked with the cylindrical tube to complete the extraction operation, and when the conical block is separated from the inner wall of the plug-in tube, the hose can be sleeved on the surface of the screw hole ring to complete the connection, and the screw hole ring is used to limit the hose, thereby improving the stability of the hose during operation and preventing the hose from sliding when the pump head squeezes the hose. Two plug-in tubes are arranged on the surface of the cylindrical tube, so that the two ends of the hose are inserted on the surface of the screw hole ring for alternate extraction operations.
[0015] When the screw hole ring of the present invention moves, the connection between the positioning ring and the connecting rod pushes the triangular plate to deform. 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 pushes 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.
[0016] The present invention provides a sieve plate inside the water inlet frame, and utilizes the sieve plate to filter the liquid to prevent impurities in the liquid from entering the inside of the hose and causing clogging of the hose. When the pump head rotates, it pushes the cross-hole rod to rotate inside the mounting frame through the contact block. When the cross-hole rod rotates, it squeezes the semicircular contact plate through the semicircular block. After being squeezed, the semicircular contact plate pushes the connecting rod to move downward through the sliding frame. When the connecting rod moves downward, it pushes the pressure plate to move through the cross. When the pressure plate moves, it uses the elasticity of the spring sheet to push the cleaning rod to clean the bottom of the sieve plate to prevent impurities from accumulating on the surface of the sieve plate and affecting the water inlet effect. At the same time, when the cross rotates, it pushes the ball to impact the inner wall of the circular hole ring through the elastic rod and generate vibration. The vibration will be transmitted to the surface of the sieve plate through the circular hole ring, further improving the cleaning effect of the sieve plate.

When the pump head 6 rotates, it pushes the cross hole rod 51 to rotate inside the mounting frame 52 through the contact block 58. When the cross hole rod 51 rotates, it squeezes the semicircular contact plate 54 through the semicircular block 53. After being squeezed, the semicircular contact plate 54 pushes the connecting rod 56 to move downward through the sliding frame 55. When the connecting rod 56 moves downward, it pushes the pressure plate 62 to move through the cross 64. When the pressure plate 62 moves, it uses the elasticity of the spring 61 to push the cleaning rod 66 to clean the bottom of the sieve plate 59.To prevent impurities from accumulating on the surface of the sieve plate 59 and affecting the water inlet effect, the cross 64 pushes the ball 65 to impact the inner wall of the circular hole ring 60 through the spring rod 63 when rotating, and generates vibration, which is transmitted to the surface of the sieve plate 59 through the circular hole ring 60, further improving the cleaning effect of the sieve plate 59.
