[0002] At present, industrial boilers or household heating are still mainly steam boilers, but they have the disadvantages of high energy consumption and serious pollution. With the improvement of environmental protection requirements and the development of technology, electromagnetic induction heating technology and rotary electromagnetic induction heating technology have gradually gained favor. Electromagnetic induction heating conversion technology uses electromagnetic conversion equipment such as induction coils to convert electrical energy into magnetic energy and then into thermal energy. Induction heating is when an alternating current passes through an inductive conductor, an alternating magnetic field is generated around it, and the workpiece in the alternating magnetic field generates an induced current, which does work and heats the workpiece. Induction heating avoids the phenomenon that electric heating tubes are easily broken down and damaged. Since there are no expired parts, maintenance is simple, but the manufacturing process is complicated, and the power supply must be equipped with a frequency conversion cabinet. Once damaged, it is difficult to repair. Rotating electromagnetic induction heating technology is an electric heating technology that uses the rotating electromagnetic effect for heating. It has the advantages of complete isolation of water and electricity, non-contact heating, rapid heating speed, easy control, etc.; currently, related heating equipment based on this technology has also been applied, but it still has the disadvantages of unreasonable structural design and low heating efficiency; based on this, the inventor has devoted himself to research and proposed a magnetic heating equipment with reasonable structural design and high heating efficiency.

[0033] In this embodiment, in order to ensure the heating effect, the magnetic heating sleeve 11 is made of copper.

[0034] The method for using the magnetic heating device comprises the following steps:

[0035] When in use, fluid medium is introduced into the water inlet; the motor 1 is started, and the motor 1 drives the rotating shaft 3 to rotate, and then drives the magnetic group rotor 4 to rotate. The magnet array I7 in the magnetic group rotor 4 generates a high-intensity magnetic field. During the high-speed rotation of the magnetic group rotor 4, the magnetic heating sleeve 11 cuts the high-intensity magnetic field, and the magnetic heating sleeve 11 generates an eddy current effect, which makes the magnetic heating sleeve 11 heat up, thereby continuously heating the fluid medium in the flow channel, and the heated fluid medium is discharged through the water outlet pipe 13, thereby providing heat energy to the outside.

[0036] As a further optimization of this embodiment, the following technical solution improvements are proposed:

[0037] The magnetic heating sleeve 11 is also connected to an upper pressure cover 15, which clamps the magnetic heating sleeve 11 with the bottom pressure cover 9; the upper pressure cover 15 is provided with a through hole 16, which is connected to the above-mentioned water inlet, and a fluid medium such as water can enter the flow channel 12 through the through hole 16; the other side of the upper pressure cover 15 is rotatably connected to an impeller 18, and the impeller 18 is made of metal; the impeller 18 is rotatably connected to one side of the upper pressure cover 15 through an axle 17; one side of the upper pressure cover 15 is connected to a top surface pressure cover 19, and the top surface pressure cover 19 and the upper pressure cover 15 are fixedly connected to the magnetic heating sleeve 11 through a second screw 21 to form a whole; the top surface pressure cover 19 is connected to a water inlet pipe 20; the top surface pressure cover 19 has a volute guide groove 22 inside; the impeller 18 is located in the volute guide groove 22; the through hole 16 is correspondingly connected to the drain outlet of the volute guide groove 22.

[0039] In addition, a magnet array II8 is also provided on the top of the magnetic group rotor 4, and the permanent magnets in the magnet array II8 are arranged alternately with N and S poles for one circle. In order to facilitate installation, an embedding groove 6 is provided at the end of the magnetic group rotor 4, and the permanent magnets in the magnet array II8 are embedded in the embedding groove 6; the permanent magnets in the magnet array I7 are in the shape of strips, and a plurality of strip grooves 5 are provided on the outer wall of the magnetic group rotor 4, and the permanent magnets in the magnet array I7 are installed in the strip grooves 5.

[0040] Through the arrangement of the magnet array II8 and the impeller 18, the fluid medium can also be driven for circulation and preheated. The specific method is as follows: It also includes driving for circulation and preheating the fluid medium. The specific method is as follows: When in use, the fluid medium is introduced into the water inlet pipe, and the fluid medium flows into the flow channel through the water inlet; when the motor 1 is started, the magnet array II8 on the magnetic group rotor 4 rotates, and the magnet array II8 also generates a rotating magnetic field. The magnetic field cuts the blade disk at the bottom of the impeller 18. The blade disk made of copper material and the rotating magnetic field will generate magnetic resistance, and the impeller 18 is driven to rotate by the magnetic resistance. The rotation of the impeller 18 can drive the circulation of the fluid medium; the rotating magnetic field and the rotation of the impeller 18 have a speed difference, and this speed difference will enable the impeller 18 to cut the magnetic field, and the impeller 18 will generate an eddy current effect, and the impeller 18 itself will also generate heat, so that the fluid medium can be preheated, which is conducive to the subsequent further heating. The above structure is arranged in combination, which can drive the circulating water and preheat the return water at the same time.

[0041] From the perspective of affecting the cutting of magnetic lines of force, in this embodiment, the upper pressure cover 15 is preferably made of glass material, because there is no mutual induction phenomenon between the magnetic lines of force and the glass material, and the effect is better than any metal material.

[0042] There are two ways to arrange the water outlet pipe 13 , one of which is: the water outlet pipe 13 is arranged on the side wall of the magnetic heating jacket 11 ; the water outlet pipe 13 is arranged perpendicular to the central axis of the magnetic heating jacket 11 .

[0043] In order to ensure the heat preservation effect, the magnetic heating device can also be detachably connected with a heat preservation sleeve 23.

[0044] The insulation sleeve 23 includes a left sleeve body and a right sleeve body, and ear seats 25 are respectively provided on the left sleeve body and the right sleeve body. The left sleeve body and the right sleeve body are connected to form the insulation sleeve 23 by passing connecting bolts through the ear seats 25; an opening 24 for the water outlet pipe 13 to pass through is opened on the left sleeve body tube; and a mounting hole for the water inlet pipe 20 to pass through is opened at the center of the insulation sleeve 23.

[0047] From the above two examples, we can see that:

[0048] The device is reasonably designed, with a compact structure and a small size. The magnetic group rotor 4 rotates and the magnetic heating sleeve 11 is fixed by adopting a structural form, and a plurality of flow channels 12 are opened in the magnetic heating sleeve 11, and the adjacent flow channels 12 are connected end to end to form a whole, which has two advantages. One is that the time for the fluid medium to enter the water outlet pipe 13 is prolonged, thereby increasing the heating time and ensuring the heating effect. The second is that the flow channels 12 are arranged circumferentially along the magnetic heating sleeve 11, and the magnetic heating sleeve 11 generates heat as a whole, so that the fluid medium in the flow channels 12 is in a heating environment all the time when flowing, which can effectively ensure the heating effect. Under the premise of a small size of the whole machine, the above structural setting can effectively ensure the final heating effect, generate high-temperature hot water through heat exchange, and output heat energy, which can be widely used in household heating or industrial heating, has the effects of low power consumption and a wide range of applications, is easy to use, and is economical and environmentally friendly.

[0049] The present invention is ingeniously designed. By setting the magnet array II8 and the rotatable impeller 18 made of copper, the magnet array II8 can drive the impeller 18 to rotate when it rotates, and the rotation of the impeller 18 can achieve the purpose of driving circulating water; in addition, there is a speed difference between the rotation of the impeller 18 and the rotation of the magnet array II8, and the speed difference can achieve the heating work of the impeller 18 and achieve the purpose of preheating. The above components are cleverly matched, which can achieve both driving circulating water and preheating the return water.
