Preferably, the hose inboard is covered with evenly and compresses tightly the magnetite, compress tightly the magnetite and pass through fixed cover and pump body connection, the position of pressing close to the hose of driver is equipped with the drive magnetite, the drive magnetite and the face that compresses tightly the magnetite and be close to each other represent for the repulsion.

Preferably, the sizes of the surfaces of the driving magnets corresponding to the pressing magnets are such that the two pressing magnets can be driven simultaneously.

Preferably, the middle of the compression magnet is provided with a magnet, and the edge of the compression magnet is provided with a non-magnet.

Preferably, the area of the magnet in the middle of the compression magnet gradually increases along the rotation direction of the driving magnet.

Preferably, the fixing sleeve is restored to the original position under the action of the pressing magnet or the gravity of the fixing sleeve.

Preferably, the inner wall of the pump body is provided with a compensation magnet, and the compensation magnet adjusts the magnetic field inside the pump body to balance the stress of the driver.

The invention has the following beneficial effects:

1. this energy-conserving peristaltic pump compresses tightly magnetite extrusion hose through the drive magnetite and the magnetic drive who compresses tightly between the magnetite and drives the liquid flow, relatively speaking, do not have the effect of frictional force when compressing tightly magnetite extrusion hose, reduce the requirement of hose, need not to consider frictional force simultaneously and stop driver pivoted problem, therefore it sets up wide relatively to compress tightly the extrusion force of magnetite to the hose, rationally set up the extrusion force, eliminate the inhomogeneous negative effects who brings that the tolerance produced, can improve peristaltic pump's reliability and improve the output precision.

2. This energy-conserving peristaltic pump, only need overcome the elasticity of hose and fixed cover self when compressing tightly the magnetite extrusion hose, it is less to receive the influence of other factors, through the reasonable repulsion size that sets up between fixed cover and the drive magnetite, can guarantee that fixed cover targets in place to the extrusion of hose, simultaneously, the magnetite that sets up at pump body inner wall can effectively ensure that the atress of driver pivot is even, improves the life of driver.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, an energy-saving peristaltic pump includes a pump body 1, a hose 2 and a driver 3, the hose 2 is disposed on an inner wall of the pump body 1, the driver 3 is disposed in a middle portion of the pump body 1, the driver 3 drives a pressing magnet 4 to press the hose 2 by magnetic force when rotating circumferentially to form a closed liquid section, the pressing magnet 4 is continuously disposed on a surface of the hose 2, and the pressing magnet 4 sequentially presses the hose 2 to move the closed liquid section in the hose 2.

Wherein, 2 inboard cloth of hose is filled with and compresses tightly magnetite 4, compress tightly magnetite 4 and be connected with the pump body 1 through fixed cover 5, the position of the hose 2 of pressing close to of driver 3 is equipped with drive magnetite 6, drive magnetite 6 and the face that compresses tightly magnetite 4 and be close to each other represent for the repulsion, drive magnetite 6 is the circular motion and makes, press close to in proper order and just to corresponding compaction magnetite 4, the drive compresses tightly magnetite 4 extrusion hose 2 under the effect of repulsion, along with the change of extrusion position, the confined liquid section moves along with drive magnetite 6 rotates.

Wherein, the size of the face that drive magnetite 6 and compress tightly magnetite 4 correspond satisfies can two simultaneous drive and compress tightly magnetite 4, along the direction of rotation of drive magnetite 6, no matter how the drive magnetite 6 removes, keeps a state that compresses tightly magnetite 4 and be in extrusion hose 2 throughout, guarantees the interior liquid unidirectional movement of hose 2.

Wherein, compress tightly 4 middle parts of magnetite and be equipped with the magnet and the edge sets up to the non-magnet, restriction drive magnetite 6 is to the effect that compresses tightly magnetite 4 for the action that compresses tightly magnetite 4 is orderly, can not receive the interference because of edge atress.

Wherein, the area of compressing tightly 4 middle part magnets of magnetite increases along 6 rotation direction of drive magnetite gradually, overcomes the influence that compresses tightly 4 self gravity of magnetite, makes and compresses tightly the extrusion force of magnetite 4 to hose 2 and keep unanimous.

Wherein, fixed cover 5 recovers the original position under the effect that compresses tightly magnetite 4 or the action of gravity of self, and fixed cover 5 is the elastomer, avoids fixed cover 5 to influence the recovery of hose 2, improves work efficiency.

Wherein, the inner wall of the pump body 1 is provided with a compensation magnet 7, the compensation magnet 7 adjusts the magnetic field in the pump body 1 to balance the stress of the driver 3, and the compensation magnet 7 provides proper repulsion force to balance the stress of the driver 3 relatively.
