[0002] In traditional plunger pump designs, the motor directly drives the rotating shaft through a mechanical connection. While simple, this design has several drawbacks. Wear and friction in the mechanical connection shorten the equipment's service life, impacting the pump's efficiency and stability. Furthermore, the mechanical connection in traditional designs carries a high risk of leakage and generates high vibration and noise, impacting the pump's overall performance and operating environment. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, the present invention provides a magnetically driven multi-chamber pump. This solves the problem of traditional plunger pump designs, where the motor directly drives the rotating shaft through a mechanical connection. While simple, this design has several drawbacks. Wear and friction in the mechanical connection shorten the equipment's service life, affecting the pump's efficiency and stability. Furthermore, the mechanical connection in traditional designs carries a high risk of leakage and produces high vibration and noise, which in turn affects the pump's overall performance and operating environment.

[0004] One embodiment of the present invention provides a magnetically driven multi-chamber pump, comprising:

[0005] driving parts;

[0006] a transmission component, the transmission component being mounted on the driving member;

[0007] a multi-chamber pump body, the multi-chamber pump body being mounted on one side of the driving member;

[0008] A driven component, the driven component being mounted on the multi-chamber pump body;

[0009] The transmission component is magnetically connected to the driven component, and the transmission end of the transmission component is sleeved on the driven end of the driven component, and the transmission component is used to drive the driven component.

[0010] The utility model discloses a magnetically driven multi-chamber pump, which drives a transmission component to rotate through a driving member. Since the transmission component is magnetically connected to the driven component, when the transmission component rotates, it generates a rotating magnetic field. The interaction between the magnetic fields therebetween generates a force, causing the driven component to rotate as well. This interaction is based on the interaction between magnetic poles, that is, the principle that opposite poles attract and like poles repel. Therefore, when the transmission component rotates, its magnetic field interacts with the driven component, thereby driving the driven component to rotate together. The use of this connectionless magnetic drive design on a multi-chamber pump can further improve the durability and reliability of the pump, reduce the risk of leakage and wear in traditional mechanical connections, and improve the sealing of the pump. In addition, this design can also reduce vibration and noise, improve working stability, and thus enhance the overall performance and efficiency of the pump.

[0011] In one embodiment, the transmission component includes a connecting component and a plurality of magnets;

[0012] One end of the connecting component is fixedly connected to the driving shaft of the driving member;

[0013] The connecting component is provided with a sleeve portion at one end away from the driving component;

[0014] The plurality of magnets are mounted on the sleeve portion in a regular array. The sleeve portion is provided with an annular groove that matches the size of the magnets. The magnets are located in the annular groove.

[0015] In one embodiment, a rotating shaft is rotatably provided in the multi-chamber pump body, and the driven component is provided on the rotating shaft.

[0016] In one embodiment, the driven component includes a sealed housing and a magnetic block.

[0017] In one embodiment, the sealing shell is fixedly arranged on one side of the multi-chamber pump body.

[0018] In one embodiment, the magnetic block is sleeved on the rotating shaft and located in the sealed housing.

[0019] In one embodiment, the sleeve portion is sleeved on the sealed housing.

[0020] In one embodiment, the central axis of the annular groove coincides with the central axis of the magnetic block.

[0021] In one embodiment, there is a gap between the magnet and the sealed housing.

[0022] In one embodiment, the magnetic block includes a rotation state;

[0023] When the magnetic block is in a rotating state, the driving member drives the connecting member and the plurality of magnets to rotate, and the magnets rotate and drive the magnetic block magnetically connected thereto to rotate.

[0024] The magnetically driven multi-chamber pump provided by the above technical solution has the following beneficial effects:

[0025] 1. The transmission component is driven to rotate by the driving member. Since the transmission component is magnetically connected to the driven component, when the transmission component rotates, it will generate a rotating magnetic field. The interaction between the magnetic fields will generate force, causing the driven component to rotate as well. This interaction is based on the interaction between magnetic poles, that is, the principle that opposite poles attract and like poles repel. Therefore, when the transmission component rotates, its magnetic field will interact with the driven component, thereby driving the driven component to rotate together. The magnetic connection between the transmission component and the driven component realizes connectionless magnetic drive.

[0026] 2. Using this connectionless magnetic drive design on multi-chamber pumps can further improve the durability and reliability of the pumps.

[0027] 3. Through the design of connectionless magnetic drive, the leakage risk and wear in traditional mechanical connections are reduced and the sealing of the pump is improved.

[0028] 4. The design of non-connected magnetic drive can also reduce the vibration and noise generated when the multi-chamber pump and the drive parts are used, improve the working stability, and thus enhance the overall performance and efficiency of the pump.

[0029] 5. Uniform distribution of magnets can provide a more uniform magnetic field, which helps to achieve a stable torque effect and reduce the vibration and instability caused by uneven magnetic field. Since the rotation of the evenly distributed magnets produces periodic magnetic force changes, more efficient energy transfer can be achieved, especially at high rotation speeds, which can effectively convert magnetic energy into mechanical energy.

[0047] Combine Figures 1 to 4 As shown, one embodiment of the present invention provides a magnetically driven multi-chamber pump, comprising:

[0048] Driving member 100;

[0049] A transmission component 200, the transmission component 200 is mounted on the driving member 100;

[0050] A multi-chamber pump body 300 , which is mounted on one side of the driving member 100 ;

[0051] A driven component 400 , wherein the driven component 400 is mounted on the multi-chamber pump body 300 ;

[0052] The transmission component 200 is magnetically connected to the driven component 400 , and the transmission end of the transmission component 200 is sleeved on the driven end of the driven component 400 . The transmission component 200 is used to drive the driven component 400 .

[0053] The utility model discloses a magnetically driven multi-chamber pump, which drives a transmission component 200 to rotate through a driving member 100. Since the transmission component 200 is magnetically connected to the driven component 400, when the transmission component 200 rotates, it generates a rotating magnetic field. The interaction between the magnetic fields therebetween generates a force, causing the driven component 400 to rotate as well. This interaction is based on the interaction between magnetic poles, that is, the principle that opposite poles attract and like poles repel. Therefore, when the transmission component 200 rotates, its magnetic field interacts with the driven component 400, thereby driving the driven component 400 to rotate together. The use of this connectionless magnetic drive design on a multi-chamber pump can further improve the durability and reliability of the pump. It can reduce the risk of leakage and wear in traditional mechanical connections, and improve the sealing of the pump. In addition, this design can also reduce vibration and noise, improve working stability, and thus enhance the overall performance and efficiency of the pump.

[0054] In one embodiment, the transmission component 200 includes a connecting component 210 and a plurality of magnets 220;

[0055] One end of the connecting member 210 is fixedly connected to the driving shaft of the driving member 100;

[0056] The end of the connecting component 210 away from the driving component 100 is provided with a sleeve portion 211;

[0057] The plurality of magnets 220 are mounted on the sleeve portion 211 in a regular array. The sleeve portion 211 is provided with an annular groove 212 that is adapted to the size of the magnets 220 , and the magnets 220 are located in the annular groove 212 .

[0058] In this embodiment, the connecting component 210 is used to connect with the driving component 100 , and a plurality of magnets 220 are mounted on the sleeve portion 211 in a circumferential array and are disposed on the inner wall of the annular groove 212 .

[0059] It should be noted that the rotation of several magnets 220 will generate a changing magnetic torque, which will generate torque on the driven component 400, attempting to keep the driven component 400 consistent with the magnetic field of the rotating magnet 220. The rotating magnet 220 changes the direction and distribution of the magnetic force, and the driven component 400 will be affected by this changing torque, thereby generating rotation.

[0060] Furthermore, the uniform distribution of the magnets 220 can provide a relatively uniform magnetic field, which helps to achieve a stable torque effect and reduce vibration and instability caused by uneven magnetic fields;

[0061] The magnetic field strength and distribution can be flexibly changed by adjusting the number and distribution of the magnets 220 , thereby optimizing the movement effect and efficiency of the magnets 220 , as described herein;

[0062] The rotating magnet 220 generates a changing magnetic torque relative to the static driven component 400. This change can enhance the torque and help increase the rotation speed and driving force of the driven component 400.

[0063] Since the rotation of the magnet 220 generates periodic magnetic force changes, more efficient energy transfer can be achieved, especially when the rotation speed is high, which can effectively convert magnetic energy into mechanical energy;

[0064] Compared with traditional mechanical transmission systems, magnetic transmission can reduce physical contact and lower friction losses, thereby improving the overall efficiency and durability of the system.

[0065] In one embodiment, a rotating shaft 500 is rotatably disposed in the multi-chamber pump body 300 , and the driven component 400 is disposed on the rotating shaft 500 .

[0066] In this embodiment, the rotating shaft 500 may be an eccentric shaft or other components that can drive the plunger component inside the multi-chamber pump to pump liquid, and this is not limited here.

[0067] In one embodiment, the driven component 400 includes a sealed housing 410 and a magnetic block 420;

[0068] The sealing shell 410 is fixedly arranged on one side of the multi-chamber pump body 300;

[0069] The magnetic block 420 is sleeved on the rotating shaft 500 and located in the sealed housing 410 .

[0070] In this embodiment, the shell is used to separate the magnetic block 420 from the plurality of magnets 220. The shell is a component that is not magnetically connected to the magnet 220 or the magnetic block 420, and is not a sole limitation here. The magnetic block 420 is used to be fixed on the rotating shaft 500. When the plurality of magnets 220 rotate, the magnetic block 420 is driven to rotate. The speed of rotation of the magnet 220 is controlled by the driving member 100, thereby controlling the speed of rotation of the magnetic block 420.

[0071] It should be noted that the side of the magnet 220 facing the magnetic block 420 and the side of the magnetic block 420 facing the magnet 220 are magnetically attracted to each other, so that when the plurality of magnets 220 rotate, the magnetic block 420 is also driven to rotate.

[0072] In one embodiment, the sleeve portion 211 is sleeved on the sealed housing 410;

[0073] The central axis of the annular groove 212 coincides with the central axis of the magnetic block 420 .

[0074] In this embodiment, the central axis of the annular groove 212 coincides with the central axis of the magnetic block 420 , indicating that the plurality of magnets 220 are sleeved around the periphery of the magnetic block 420 , thereby driving the magnetic block 420 to rotate as the plurality of magnets 220 rotate.

[0075] In one embodiment, there is a gap between the magnet 220 and the sealed housing 410 .

[0076] In this embodiment, a gap needs to be reserved between the magnet 220 and the sealed housing 410. This is because if the distance between the magnetic block 420 and the magnet 220 is too close, the mutual repulsion or attraction of the strong magnetic field may cause system instability or damage to the equipment. Leaving an appropriate gap can ensure that the magnetic field acts more uniformly while avoiding physical collisions or interference caused by strong magnetic forces.

[0077] In one embodiment, the magnetic block 420 includes a rotation state;

[0078] When the magnetic block 420 is in a rotating state, the driving member 100 drives the connecting member 210 and the plurality of magnets 220 to rotate, and the magnets 220 rotate and drive the magnetic block 420 magnetically connected thereto to rotate.

[0079] In this embodiment, the rotation of the plurality of magnets 220 generates a changing magnetic torque, which generates a torque on the driven component 400, attempting to keep the magnetic block 420 consistent with the magnetic field of the rotating magnet 220. The rotating magnet 220 changes the direction and distribution of the magnetic force, and the magnetic block 420 is subjected to this changing torque, thereby generating rotation.

[0080] It should be noted that the liquid suction component in the multi-chamber pump body 300 is driven to move repeatedly by the rotation of the rotating shaft, thereby performing the action of sucking and discharging liquid. The multi-chamber pump body 300 can be a plunger pump or other component that drives the liquid suction component inside it to move repeatedly by the rotating shaft. No further restrictions are made here.

[0081] Furthermore, the claims do not elaborate on the structure of the pump, because the innovative structure of the present invention is not the pump body, but the transmission component 200 and the driven component 400, which are described here.

[0082] The working principle of this utility model:

[0083] The driving member 100 drives the connecting member 210 and several magnets 220 to rotate. The rotation of the several magnets 220 will generate a changing magnetic torque. This magnetic torque generates torque on the driven member 400, trying to make the magnetic block 420 consistent with the magnetic field of the rotating magnet 220. The rotating magnet 220 changes the direction and distribution of the magnetic force. The magnetic block 420 will be affected by this changing torque, thereby generating rotation. After the magnetic block 420 rotates, it drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the suction component in the multi-chamber pump body 300 to make repeated movements, thereby performing the actions of sucking and discharging liquid.

[0084] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the paper version and drawings of the present invention under the practical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
