[0043] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0044] Example 1

[0045] To further illustrate the cleaning effect of the magnetic cleaning device of this embodiment, this embodiment discloses a magnetic cleaning device. Figures 1 to 4 , wherein, illustratively, the magnetic component is a magnetic bead, and in actual applications, the magnetic component can also make other magnetic products.

[0046] The magnetic cleaning device comprises:

[0047] Magnetic bar 1,

[0048] Specifically, the magnetic bar 1 provides magnetic force. In practical applications, the magnetic bar 1 can also be replaced by other materials that can provide adsorption force.

[0049] A sleeve 2, wherein the sleeve 2 is adapted to fit the magnetic bar 1;

[0050] Specifically, the magnetic bar 1 can be inserted into the magnetic sleeve, so that the surface of the magnetic sleeve generates magnetic force.

[0051] A working container, used to contain the sleeve 2 and the magnetic beads to be cleaned;

[0052] Specifically, the working container serves as a cleaning space for accommodating the sleeve 2 and the magnetic beads to be cleaned, so that the magnetic beads can be cleaned quickly and the magnetic beads can be dispersed in the space of the working container.

[0053] A driving component, wherein the driving component is connected to the magnetic rod 1, and the driving component drives the magnetic rod 1 to be inserted into or withdrawn from the sleeve 2,

[0054] Specifically, since the driving assembly is connected to the magnetic rod 1 , the driving assembly can drive the magnetic rod 1 to move, so that the magnetic rod 1 is inserted into or withdrawn from the sleeve 2 .

[0055] Among them, when the magnetic rod 1 is inserted into the magnetic sleeve, magnetic force is generated on the surface of the sleeve 2, and the sleeve 2 is located in the working container. Under the action of the magnetic force on the surface of the sleeve 2, the magnetic beads in the working container can be quickly adsorbed on the sleeve 2. Since the magnetic force of the magnetic rod 1 is strong, the magnetic beads can be preferentially evenly distributed on the magnetic sleeve without mutual magnetic attraction between the magnetic beads. At this time, the magnetic beads are dispersedly adsorbed on the surface of the sleeve 2, so that each magnetic bead can be cleaned.

[0056] When the magnetic rod 1 is pulled out of the magnetic sleeve, the surface of the sleeve 2 loses its magnetic force, and the sleeve 2 is located in the working container. The magnetic beads originally adsorbed on the sleeve 2 detach from the sleeve 2 and fall back into the working container, making it easy to collect the magnetic beads after cleaning.

[0057] The above-mentioned magnetic cleaning device is provided with a magnetic rod 1 and a sleeve 2 on the basis of a working container. Since the magnetic rod 1 can be movably inserted into the sleeve 2 through a driving assembly, when the magnetic rod 1 is inserted into the sleeve 2 in the working container, the magnetic rod 1 can magnetically attract the magnetic parts in the working container to the sleeve 2 and evenly distribute them on the sleeve 2 under the action of gravity. At this time, the evenly dispersed magnetic parts can be fully cleaned, the cleaning efficiency is improved, and the problem of uneven dispersion of magnetic parts in the prior art resulting in poor cleaning effect is avoided. In addition, the above-mentioned magnetic cleaning device can better disperse the magnetic parts, so a larger capacity can be set to accommodate more magnetic parts to meet the needs of cleaning magnetic parts.

[0058] Example 2

[0059] See also Figures 1 to 4 The magnetic beads will have the problem of insufficient cleaning effect if they only rely on the flushing effect of the cleaning liquid in the working container. On the basis of the above embodiments, in order to further improve the cleaning effect of the magnetic beads, on the basis of Example 1, this embodiment also discloses that the driving component is also connected to the sleeve 2, and the driving component drives the sleeve 2 and the magnetic rod 1 to move out of the working container synchronously.

[0060] Specifically, the driving component can control the movement of the magnetic bar 1 and the sleeve 2 respectively. On the one hand, the driving component drives the magnetic bar 1 to be inserted into the sleeve 2 or withdrawn from the sleeve 2; on the other hand, when the magnetic bar 1 is inserted into the sleeve 2, the driving component can move the magnetic bar 1 and the magnetic sleeve at the same time, so that the magnetic bar 1 can move simultaneously with the magnetic sleeve when it is inserted into the sleeve 2, so that the magnetic part can be adsorbed on the surface of the magnetic sleeve and can continuously move back and forth in the cleaning liquid of the working container, so that the magnetic part can rub and interact with the cleaning liquid, thereby improving the cleaning efficiency.

[0061] Furthermore, under the impact of the cleaning liquid, the magnetic parts on the sleeve move and can be better and more evenly dispersed on the magnetic sleeve, further improving the cleaning effect.

[0062] Illustratively, the sleeve 2 is vertically placed in the working container, the magnetic rod 1 is located directly above the sleeve 2, and the magnetic rod 1 is vertically inserted into the sleeve 2 directly above; therefore, the sleeve 2 and the magnetic rod 1 are adapted, separated or synchronously moved in the vertical direction. In actual applications, the sleeve 2 and the magnetic rod 1 can also be adapted and separated in other ways, as long as the magnetic parts can be adsorbed and moved.

[0063] In this embodiment, the driving assembly includes a first pulley transmission mechanism 3 and a second pulley transmission mechanism 4. The first pulley transmission mechanism 3 is connected to the magnetic bar 1 through its first belt 31 and drives the magnetic bar 1 to move;

[0064] The first pulley transmission mechanism 3 is connected to the sleeve 2 via its second belt 41 and drives the sleeve 2 to move.

[0065] Specifically, each pulley transmission mechanism includes a gear and a belt. The belt is arranged on the gear. The gear is driven to rotate by a servo motor, the gear drives the belt, and the belt drives the magnetic bar 1 and the sleeve 2 to control the lifting of the magnetic bar 1 and the sleeve 2.

[0066] Example 3

[0067] See also Figures 1 to 4 In order to further enable the magnetic bar 1 to generate magnetic force stably and evenly in the magnetic sleeve, based on the above embodiment, this embodiment discloses that a fixing sleeve 5 is sleeved in the sleeve 2, wherein one end of the fixing sleeve 5 is fixedly connected to a limiting plate 6, and the other end is inserted into the sleeve 2, and the limiting plate 6 is fixedly mounted on the port of the sleeve 2;

[0068] The magnetic bar 1 is inserted into the sleeve 2 through the fixing sleeve 5, and the fixing sleeve 5 holds the magnetic bar 1;

[0069] The limiting plate 6 is connected to the second belt 41 .

[0070] Specifically, a partial fixing sleeve 5 is additionally provided at the docking position of the sleeve 2, and the fixing sleeve 5 can partially narrow the sleeve 2, play a role in positioning the magnetic bar 1, and prevent the magnetic bar 1 from shaking in the sleeve 2. On the one hand, the limiting plate 6 limits the fixing sleeve 5 to be set at the end position of the sleeve 2, providing a position for the installation of the fixing sleeve 5, and on the other hand, the limiting plate 6 can be used to connect with the second belt 41 to realize the movement of the sleeve 2 driven by the second pulley transmission mechanism 4.

[0071] If the entire magnetic rod 1 is magnetic, the portion of the magnetic rod 1 that has not entered the magnetic sleeve will also absorb the magnetic beads, resulting in the subsequent inability to properly detach the magnetic beads from the magnetic rod. In this regard, the present embodiment further discloses that the magnetic rod 1 includes a non-magnetic rod body 102, the proximal end of the non-magnetic rod body 102 is inserted into the sleeve 2, and the proximal end of the non-magnetic rod body 102 is coated with a magnetic material 101;

[0072] Specifically, the magnetic material 101 is only provided on the portion of the magnetic rod 1 inserted into the sleeve 2 , so that the magnetic attraction position can be better controlled to prevent the magnetic beads from being directly adsorbed onto the magnetic rod 1 and affecting the falling of the magnetic beads.

[0073] In order to ensure that the magnetic bar 1 and the first pulley transmission mechanism 3 can be installed together better, a mounting plate 8 is connected to the far end of the non-magnetic rod body 102 , and the mounting plate 8 is connected to the first belt 31 .

[0074] In addition, the diameter of the magnetic bar 1 is 10-25 mm, and the length of the magnetic bar 1 is 150-300 mm. The size of the magnetic bar 1 can be selected according to actual conditions and is not limited here.

[0075] Exemplarily, seven magnetic rods 1 are provided, and seven magnetic sleeves are provided correspondingly, and the seven magnetic rods 1 are inserted into the corresponding seven magnetic sleeves. The magnetic sleeves can be made of insulating material or metal material, as long as the magnetic force can penetrate into the magnetic sleeves.

[0078] Specifically, the container body 9 is detachably arranged on the base 10, and a heater 11 is arranged on the upper side of the base 10, so that the container body 9 can be heated, so that the cleaning liquid in the container body 9 is heated to improve the cleaning efficiency; at the same time, an ultrasonic device 12 is arranged on the base 10, and the ultrasonic device 12 can perform ultrasonic vibration on the solution in the container body 9 to improve the cleaning effect.

[0079] The heater 11 includes two semicircular metal bath heating plates, which are installed on both sides of the sliding circular base 10 and fit the outer surface of the bottom of the non-metallic circular container body 9 .

[0080] The ultrasonic device 12 includes an ultrasonic transducer with a circular cross-section, and the ultrasonic transducer is mounted on the working surface of the base 10 .

[0081] In this embodiment, a liquid extraction and injection component is also included. The liquid extraction and injection component is connected to the container body 9 and is used to inject liquid into the container body 9 or extract liquid from the container body 9.

[0082] Specifically, the liquid extraction and injection assembly includes a liquid injection pump, a liquid extraction pump, a liquid injection pipe, a telescopic liquid extraction pipe and a motor. One end of the liquid injection pipe is connected to an external liquid inlet connector, and the other end is connected to the liquid injection pump. The telescopic liquid extraction pipe is a section of metal pipe, which is controlled to rise and fall by a motor, one end of which is connected to the liquid extraction pump, and the other end is connected to the liquid discharge connector. The function of the liquid extraction and injection assembly is to control the cleaning liquid in the container body 9, for example, to extract dirty cleaning liquid or inject clean cleaning liquid.

[0083] In this embodiment, the container body 9 is provided with a first liquid level sensor 15 and a second liquid level sensor 16;

[0084] The first liquid level sensor 15 is disposed at the bottom of the container body 9 and connected to the liquid pump, and is used to monitor the lowest liquid level of the liquid to avoid excessive liquid extraction.

[0085] The second liquid level sensor 16 is disposed at the set liquid level line of the container body 9 and is connected to the injection pump, and is used to monitor the maximum liquid level of the injection to avoid excessive injection.

[0086] Exemplarily, the container body 9 is a non-metallic round flat-bottomed barrel with a diameter of 250 mm and a capacity of 5000 ml. The first liquid level sensor 15 is installed at the bottom of the container body 9, and the second liquid level sensor 16 is installed at the volume scale line of 5000 ml for controlling the liquid addition level.

[0095] After the mixing is completed, the magnetic rod 1 is lowered and inserted into the sleeve 2, so that the sleeve 2 performs magnetic adsorption and magnetic separation;

[0097] The suction tube is controlled to descend to the specified position, the suction pump is started, and the lower liquid level sensor controls the suction time. When all the waste liquid is sucked away, the suction is stopped, the suction tube rises, and returns to the initial position.

[0099] When the magnetic rod 1 rises to the set position, the injection pump starts to inject new working fluid, and the second liquid level sensor 16 controls the height of the injected liquid.
