Description

Technical Field

[0001] The utility model relates to the technical field of peristaltic pumps, and specifically relates to a novel peristaltic pump. Background Technique

[0002] A peristaltic pump is like using a finger to pinch a hose filled with fluid. As the finger slides forward, the fluid inside the tube moves forward. The peristaltic pump works on the same principle, except that the finger is replaced by a roller. The fluid is pumped by alternately squeezing and releasing the elastic delivery hose of the pump. Just like squeezing a hose with two fingers, as the fingers move, a negative pressure is formed inside the tube, and the liquid flows accordingly.

[0003] When a traditional peristaltic pump is in use, when the peristaltic pump fixes the pipeline, the fixing of the hose is often open or embedded, so that the roller and the peristaltic tube are exposed. When the peristaltic tube is under the extrusion of the roller and generates negative pressure, although it is convenient to observe the state of the hose, during the use process, when the user checks the hose without shutting down the equipment, the roller will pose a great safety hazard to the user's finger. Once the finger is crushed by the roller, the user will be injured. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 5 , a new type of peristaltic pump, including an equipment body 1. A drive shaft 2 is rotatably connected to the inner cavity of the equipment body 1. A rolling plate 3 is installed on the outer wall of the drive shaft 2. A rolling wheel 4 is rotatably connected to the outer wall of the rolling plate 3. A rolling chamber 5 is opened in the inner cavity of the equipment body 1. A hose joint 6 is installed in the inner cavity of the equipment body 1. A closed chamber 7 is fixedly assembled on the outer wall of the equipment body 1. A closing plate 8 is movably sleeved in the inner cavity of the closed chamber 7. A moving groove 9 is opened in the inner cavity of the closed chamber 7. A supporting wheel 10 is rotatably connected to the inner wall of the moving groove 9. A trigger plate 11 is installed in the inner cavity of the equipment body 1. A trigger rod 12 is installed on the outer wall of the drive shaft 2. A pulling groove 13 is opened on the outer wall of the closing plate 8.

[0022] By providing the closed chamber 7 on the outer wall of the equipment body 1 and the closing plate 8 in the inner cavity of the closed chamber 7, the inner cavity of the equipment body 1 can be blocked under the action of the closing plate 8 and the closed chamber 7, so that the rolling plate 3 and the rolling wheel 4 in the inner cavity of the equipment body 1 can operate in a closed environment, thereby improving the use safety of the equipment.

[0023] In a preferred implementation manner: the shape of the inner wall of the moving groove 9 matches the shape of the outer wall of the closing plate 8, and the thickness of the closing plate 8 is equal to the thickness of the moving groove 9.

[0024] By opening the moving groove 9 in the inner cavity of the closed chamber 7, the outer wall of the closing plate 8 can move back and forth along the inner wall of the closed chamber 7, so that the closing plate 8 can be moved out of the inner cavity of the closed chamber 7. At this time, the rolling plate 3 and the rolling wheel 4 in the inner cavity of the rolling chamber 5 can be maintained and serviced. Under the action of the closed chamber 7 and the closing plate 8, the rolling plate 3 and the rolling wheel 4 are enclosed in the inner cavity of the rolling chamber 5, improving the use safety of the equipment.

[0025] In a preferred embodiment: The outer wall of the support wheel 10 contacts the outer wall of the closing plate 8. A controller and an indicator light are installed on the top of the equipment body 1, and the controller is electrically connected to the indicator light and the trigger plate 11.

[0026] By arranging the support wheel 10 on the inner wall of the moving groove 9, the support wheel 10 can play a certain supporting role for the closing plate 8, enabling the outer wall of the closing plate 8 to roll on the outer wall of the support wheel 10, so as to better move the closing plate 8 out of the inner cavity of the closing bin 7.

[0027] In a preferred embodiment: An electrode plate is installed on the outer wall of the trigger plate 11, and the outer wall of the trigger rod 12 fits with the outer wall of the trigger plate 11.

[0028] By installing the electrode plate on the outer wall of the trigger plate 11 and the trigger rod 12 on the outer wall of the drive shaft 2, when the drive shaft 2 rotates, every time the drive shaft 2 rotates one circle, the trigger rod 12 will contact the electrode plate on the outer wall of the trigger plate 11 under its action, thereby generating an electrical signal.

[0029] In a preferred embodiment: The number of the rolling wheels 4 is four, and the four rolling wheels 4 are respectively installed at both ends of the outer wall of the rolling plate 3.

[0030] By installing a hose in the inner cavity of the rolling bin 5, and connecting both ends of the outer wall of the hose to the upper and lower hose connectors 6 respectively, when the rolling plate 3 rotates under the action of the drive shaft 2, the outer wall of the rolling wheel 4 will squeeze the outer wall of the hose, causing the hose to deform, so that the inner cavity of the hose generates negative pressure, playing a role in extracting the liquid.

[0031] In a preferred embodiment: An observation window is opened on the outer wall of the closing bin 7, and the outer wall shape of the observation window matches the inner wall shape of the rolling bin 5. Both the closing bin 7 and the closing plate 8 are made of stainless steel.

[0032] Through the observation window opened on the outer wall of the closing bin 7, the closing plate 8 can close the observation window, so that the inner cavity of the rolling bin 5 is closed, enabling the rolling plate 3 and the rolling wheels 4 to rotate in a closed state. When it is necessary to repair the hose in the inner cavity of the rolling bin 5, only the closing plate 8 needs to be opened.

[0033] Working principle: During the use of the above-mentioned device, the rotation of the rolling pressure plate 3 is driven by the driving shaft 2. At this time, a hose is installed in the inner cavity of the rolling pressure chamber 5, and both ends of the hose are respectively connected to the hose connectors 6. As the rolling pressure plate 3 rotates, the outer wall of the rolling pressure wheel 4 will squeeze the outer wall of the hose, thereby generating a certain negative pressure to drive the movement of the liquid. During the rotation of the rolling pressure plate 3 and the rolling pressure wheel 4, the outer wall of the device body 1 can be sealed under the action of the closed chamber 7 and the closing plate 8, so that during the operation of the device, there will be no safety hazards to the user. When it is necessary to replace and repair the hose in the inner cavity of the rolling pressure chamber 5, first stop the rotation of the driving shaft 2. When the driving shaft 2 stops rotating, if the outer wall of the trigger rod 12 does not contact the contact plate on the outer wall of the trigger plate 11 at this time, the control board will not receive an electrical signal for a period of time. If the outer wall of the trigger rod 12 just contacts the contact plate on the outer wall of the trigger plate 11 when the driving shaft 2 stops rotating, and only one electrical signal is received at this time, it can be explained that the power output shaft has stopped rotating. At this time, the closing plate 8 can be pulled out from the inner cavity of the closed chamber 7, and then the rolling pressure plate 3, the rolling pressure wheel 4 and the hose in the inner cavity of the rolling pressure chamber 5 can be repaired. Only when the driving shaft 2 has completely stopped, when the driving shaft 2 has not completely stopped rotating, the controller will continuously receive the signal generated by the electrode plate on the outer wall of the trigger plate 11 for a period of time. At this time, the indicator light will be continuously lit, which can remind the user that the driving shaft 2 has not completely stopped rotating.

[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
