During use, the first magnetic field generator and the second magnetic field generator can generate a magnetic field acting on the storage space, thereby affecting the food ingredients in the storage space. During freezing, the magnetic field can limit the freedom of water molecules, causing hydrogen bonds in water molecule clusters to break, thereby inhibiting crystal nucleus growth in food ingredients and resulting in small ice crystals inside the food ingredients, thus reducing cell damage caused by ice crystals. Therefore, it helps reduce juice loss after thawing, thereby reducing nutritional loss and maintaining food taste. During refrigeration, the magnetic field can lower the supercooling degree of food ingredients, meaning that under the magnetic field, food ingredients can maintain an unfrozen state at lower temperatures. In other words, it can lower the refrigeration temperature of food ingredients, thereby further reducing bacterial growth and helping preserve food freshness. Additionally, with the first magnetic field generator and the second magnetic field generator positioned on both sides of the magnetic conductive plate, their magnetic fields can be guided by the magnetic conductive plate, resulting in more uniform magnetic field distribution in the storage space. This achieves optimal magnetic field preservation effects at lower costs.
Furthermore, by disposing the magnetic field device inside the storage space with gaps between the magnetic field device and two opposite inner side walls of the storage space, and given the special structure of the magnetic field device where the first magnetic field generator and the second magnetic field generator are disposed on both sides of the magnetic conductive plate, the magnetic conductive plate can guide and disperse the magnetic fields from the first magnetic field generator and the second magnetic field generator towards both sides of the storage space, thereby further improving the uniformity of magnetic field distribution in the storage space and helping enhance food preservation effects.

As shown in Figs. 1 to 3, in one embodiment, the storage container includes a storage body 100 and a magnetic field device 200. The storage body 100 forms a storage space 101. The magnetic field device 200 is disposed on the inner wall of the storage space 101 to generate a magnetic field in the storage space 101. The magnetic field device 200 includes a first magnetic field generator 210, a second magnetic field generator 220, and a magnetic conductive plate 230. The first magnetic field generator 210 and the second magnetic field generator 220 are disposed on two sides of the magnetic conductive plate 230.
Referring to Figs. 1 to 3, specifically, the first magnetic field generator 210 and the second magnetic field generator 220 are magnetic sheets. The two magnetic sheets are attached to both sides of the magnetic conductive plate 230, in other words, the two magnetic sheets clamp the magnetic conductive plate 230. The area of the mounting surface of the magnetic conductive plate 230 where the first magnetic field generator 210 is mounted is larger than the area of the first magnetic field generator 210, ensuring that the projection of the first magnetic field generator 210 on the mounting surface falls within the mounting surface. The area of the mounting surface of the magnetic conductive plate 230 where the second magnetic field generator 220 is mounted is larger than the area of the second magnetic field generator 220, ensuring that the projection of the second magnetic field generator 220 on the mounting surface falls within the mounting surface. The storage body 100 is a drawer, and during use, the opening of the drawer faces upward.
Continuing to refer to Figs. 1 to 3, in one implementation of this embodiment, the magnetic field device 200 is disposed on the inner bottom wall of the storage space 101. Since both the magnetic sheets and the magnetic conductive plate 230 are flat structures, the magnetic field device 200 as a whole can also be considered as a flat structure. Therefore, it can also be said that the magnetic field device 200 covers the inner bottom wall of the storage space 101, with the side of the magnetic conductive plate 230 mounted with the first magnetic field generator 210 facing the drawer opening, and the side mounted with the second magnetic field generator 220 facing the inner bottom wall of the drawer.
It should be noted that alternatively, the side of the magnetic conductive plate 230 mounted with the second magnetic field generator 220 can face the drawer opening, and the side mounted with the first magnetic field generator 210 can face the inner bottom wall of the drawer. Additionally, the magnetic field device 200 can also be disposed on the inner side walls of the storage space 101, that is, on the inner left side wall, inner right side wall, inner back side wall, and inner front side wall.
Combining Figs. 1 and 4, in one implementation of this embodiment, the magnetic field device 200 is disposed on the outer bottom wall of the storage space 101 to generate a magnetic field in the storage space 101. Specifically, it can also be said that the magnetic field device 200 covers the outer bottom wall of the drawer. Additionally, the magnetic field device 200 can be directly fixed to the outer bottom wall of the drawer. Alternatively, a recessed plate with a groove can be provided, where the magnetic field device 200 is first placed in the groove of the recessed plate, and then the recessed plate is fixed to the storage body 100, thereby fixing the magnetic field device 200 in the space formed by the groove and the outer bottom wall of the drawer.
Furthermore, it should be noted that the magnetic field device 200 can also be disposed on the outer side walls of the drawer, that is, on the outer left side wall, outer right side wall, outer back side wall, and outer front side wall.
In this embodiment, the magnetic field device 200 is disposed inside or on the outer wall of the storage space 101, and the magnetic field device 200 includes a magnetic conductive plate 230 and a first magnetic field generator 210 and a second magnetic field generator 220 disposed on both sides of the magnetic conductive plate 230. During use, when powered, the first magnetic field generator 210 and the second magnetic field generator 220 can generate a magnetic field acting on the storage space 101, thereby affecting the food ingredients in the storage space 101. During freezing, the magnetic field can limit the freedom of water molecules, causing hydrogen bonds in water molecule clusters to break, thereby inhibiting crystal nucleus growth in food ingredients and resulting in small ice crystals inside the food ingredients, thus reducing cell damage caused by ice crystals. Therefore, it helps reduce juice loss after thawing, thereby reducing nutritional loss and maintaining food taste.
During refrigeration, the magnetic field can lower the supercooling degree of food ingredients, meaning that under the magnetic field, food ingredients can maintain an unfrozen state at lower temperatures. In other words, it can lower the refrigeration temperature of food ingredients, thereby further reducing bacterial growth and helping preserve food freshness.
Additionally, with the first magnetic field generator 210 and the second magnetic field generator 220 positioned on both sides of the magnetic conductive plate 230, their magnetic fields can be guided by the magnetic conductive plate 230, resulting in more uniform magnetic field distribution in the storage space 101. This achieves optimal magnetic field preservation effects at lower costs.
Referring to Fig. 1, furthermore, two magnetic poles of the first magnetic field generator 210 and two magnetic poles of the second magnetic field generator 220 are distributed in the same direction, and the distribution direction of the two magnetic poles of the first magnetic field generator 210 is perpendicular to the surface of the magnetic conductive plate 230 on which the first magnetic field generator 210 is mounted.
Referring to Fig. 1, specifically, the distribution direction of the N poles and S poles of the two magnetic sheets is the same, and the distribution direction is perpendicular to the surface of the magnetic conductive plate 230 used for mounting the magnetic sheets. For example, if the upper surface of the magnetic sheet above the magnetic conductive plate 230 is the N pole and the lower surface is the S pole, then the magnetic sheet below the magnetic conductive plate 230 similarly has the upper surface as the N pole and lower surface as the S pole. This allows the magnetic fields of the first magnetic field generator 210 and the second magnetic field generator 220 to superimpose, helping enhance the magnetic field strength.
Additionally, preferably, the magnetic conductive plate 230 is made of a material having a relative magnetic permeability greater than 1, such as ferromagnetic material or permanent magnetic material. Here, relative magnetic permeability refers to the ratio of the material's magnetic permeability to vacuum magnetic permeability.
As shown in Figs. 1 and 5, in one embodiment, the magnetic field device 200 is disposed inside the storage space 101, and gaps exist between the magnetic field device 200 and two opposite inner side walls of the storage space 101, and two sides of the magnetic conductive plate 230 on which the first magnetic field generator 210 and the second magnetic field generator 220 are mounted face the two opposite inner side walls of the storage space having gaps with the magnetic field device 200.
Furthermore, the storage container also includes a supporting component 300. The supporting component 300 is located inside the storage space 101, and the magnetic field device 200 is fixed on the supporting component 300, thereby disposing the magnetic field device 200 inside the storage space 101.
Referring to Figs. 1 and 5, in one implementation of this embodiment, the supporting component 300 is plate-shaped and has an accommodation groove, and the magnetic field device 200 is disposed in the accommodation groove. Specifically, one end of the plate-shaped supporting component 300 contacts the back wall of the drawer, and the other end contacts the front wall of the drawer, thereby dividing the storage space 101 of the drawer into two parts distributed on the left and right. The supporting component 300 forms an accommodation groove, and the magnetic field device 200 is disposed in the accommodation groove. It should be noted that in Fig. 5, the magnetic field device 200 is shown in dotted lines to indicate it is being viewed through transparency.
Specifically, the thickness of the supporting component 300 is greater than the thickness of the magnetic field device 200, thereby creating an accommodation groove in the supporting component 300 with a thickness greater than or equal to the thickness of the magnetic field device 200. The opening of the accommodation groove faces the drawer opening, allowing the magnetic field device 200 to be directly inserted into the accommodation groove from above the drawer opening, thereby positioning the magnetic field device 200 inside the storage space 101. Moreover, gaps exist between the magnetic field device 200 and the opposite left and right inner side walls of the storage space 101. The two sides of the magnetic conductive plate 230 on which the first magnetic field generator 210 and the second magnetic field generator 220 are mounted face the left and right inner side walls of the storage space 101, meaning one magnetic sheet is positioned between the left side wall of the storage space 101 and the magnetic conductive plate 230, and the other magnetic sheet is positioned between the right side wall of the storage space 101 and the magnetic conductive plate 230.
In this embodiment, by disposing the magnetic field device 200 inside the storage space 101 and maintaining gaps between the magnetic field device 200 and two opposite inner side walls of the storage space 101, and given the special structure of the magnetic field device 200 where the first magnetic field generator 210 and the second magnetic field generator 220 are disposed on both sides of the magnetic conductive plate 230, the magnetic conductive plate 230 can guide and disperse the magnetic fields from the first magnetic field generator 210 and the second magnetic field generator 220 towards both sides of the storage space 101, thereby further improving the uniformity of magnetic field distribution in the storage space 101 and helping enhance food preservation effects. Additionally, it helps improve the magnetic uniformity efficiency of the magnetic conductive plate 230.
Furthermore, by creating an accommodation groove in the supporting component 300 for the magnetic field device 200, it provides protection for the magnetic field device 200 and prevents it from being impacted.
It should be noted that the supporting component 300 can also contact the left and right side walls of the drawer, thereby dividing the storage space 101 of the drawer into two parts distributed front and back. In other words, the side of the magnetic conductive plate 230 mounted with the first magnetic field generator 210 should be perpendicular to the plane where the drawer opening is located.
Additionally, the opening of the accommodation groove in the supporting component 300 can also face the side wall of the drawer, meaning that when assembled, the opening of the accommodation groove is blocked by the side wall of the drawer. In this case, during assembly, the magnetic field device 200 needs to be placed in the accommodation groove first, then the assembled unit of the magnetic field device 200 and supporting component 300 is installed inside the storage space 101. Alternatively, a hollow area corresponding to the opening of the accommodation groove can be created in the drawer's side wall. Or, the side wall of the drawer can be recessed inward to the storage space 101 to form a slot, with the opening of the accommodation groove corresponding to the slot opening, allowing the supporting component 300 to be inserted into the slot, and then the magnetic field device 200 can be inserted into the accommodation groove through the slot opening.
Combining Figs. 1 and 6, in one implementation of this embodiment, the supporting component 300 is a partition plate, and the magnetic field device 200 is disposed on the surface of the partition plate to be positioned inside the storage space 101. For example, the partition plate connects with the front and back inner side walls of the drawer, and the magnetic field device 200 is attached to either the surface of the partition plate facing the left inner side wall or the surface facing the right inner side wall of the drawer.
It should also be noted that the supporting component 300 can be either separately formed from the storage body 100 and later assembled together, or integrally formed. In the solution where the supporting component 300 has an accommodation groove, the side wall of the drawer can be recessed inward to the storage space 101 to form the accommodation groove, making the supporting component 300 integrally formed with the drawer.
As shown in Figs. 7 and 8, in one implementation of this embodiment, the supporting component 300 includes a base plate 310, a main support plate 320, a first auxiliary support plate 330, and a second auxiliary support plate 340. The main support plate 320, first auxiliary support plate 330, and second auxiliary support plate 340 protrude from the surface of the base plate 310 in the same direction and are parallel to each other. The main support plate 320 is located between the first auxiliary support plate 330 and the second auxiliary support plate 340, and the magnetic field device 200 is disposed on the main support plate 320. The side wall of the storage body 100 is recessed inward to the storage space 101 to form a mounting groove, and when the supporting component 300 is assembled with the storage body 100, the main support plate 320 is embedded in the mounting groove. Moreover, the first auxiliary support plate 330 and the second auxiliary support plate 340 are located outside two opposite outer side walls of the storage body 100 respectively.
Referring to Figs. 7 and 8, specifically, the back wall and bottom wall of the drawer are recessed inward to the storage space 101 to form a mounting groove, meaning the mounting groove has openings at the back and bottom sides of the drawer. The supporting component 300 with the fixed magnetic field device 200 can be assembled with the drawer either from back to front or from bottom to top, thereby embedding the main support plate 320 into the mounting groove while positioning the first auxiliary support plate 330 and the second auxiliary support plate 340 outside the left and right side walls of the drawer respectively.
In this embodiment, by configuring the supporting component 300 with a base plate 310, main support plate 320, first auxiliary support plate 330, and second auxiliary support plate 340, when assembling the supporting component 300 with the storage body 100, the assembly can be achieved through the contact between the base plate 310, main support plate 320, first auxiliary support plate 330, second auxiliary support plate 340 and the storage body 100, as well as the clamping effect between the main support plate 320 and the first auxiliary support plate 330, second auxiliary support plate 340. This eliminates the need for additional connecting parts, helping simplify the assembly process between the storage body 100 and the supporting component 300.
It should be noted that grooves can also be directly made in the back wall and bottom wall of the drawer to achieve the assembly of the supporting component 300.
It should also be noted that since the drawer is a storage body that needs to move during use, two walls of the drawer need to be adjusted to accommodate the supporting component. For fixed storage bodies, only the side wall of the storage body 100 facing the own opening of the storage body 100 needs to be recessed inward to the storage space 101 to form a mounting groove.
As shown in Fig. 9, furthermore, the storage container includes two magnetic field components 400, which are disposed on the inner sides or outer sides of the two opposite side walls of the storage space 101 that face the two sides of the magnetic conductive plate 230 on which the first magnetic field generator 210 and the second magnetic field generator 220 are mounted.
Specifically, the two sides of the magnetic conductive plate 230 on which the first magnetic field generator 210 and the second magnetic field generator 220 are mounted face the left and right side walls of the storage space 101, and the two magnetic field components 400 are installed on the outer sides of the left and right side walls of the drawer respectively. Each magnetic field component 400 includes a magnetic member and a magnetic uniformity plate, which are attached together to form an integral plate-like structure. For example, the magnetic member can be a magnetic sheet or coil, with the coil generating a magnetic field when powered. Additionally, the magnetic field component 400 can also include only the magnetic member.
It should be noted that the magnetic field components 400 can also be disposed on the inner side walls of the drawer.
Additionally, it should be noted that when the two sides of the magnetic conductive plate 230 on which the first magnetic field generator 210 and the second magnetic field generator 220 are mounted face the front and back side walls of the storage space 101, the two magnetic field components 400 are installed on the outer sides or inner sides of the front and back side walls of the drawer respectively.
In this embodiment, by disposing magnetic field components 400 on the inner sides or outer sides of the two opposite side walls of the storage space 101 that face the two sides of the magnetic conductive plate 230 on which the first magnetic field generator 210 and the second magnetic field generator 220 are mounted, it helps enhance the magnetic field strength inside the storage space 101 and further improves the uniformity of magnetic field distribution inside the storage space 101.
It should be noted that when the magnetic field device 200 is disposed on the supporting component 300, and the supporting component 300 has the main support plate 320, first auxiliary support plate 330, and second auxiliary support plate 340, the magnetic field components 400 can be disposed either on the side walls of the storage body 100 or on the first auxiliary support plate 330 and second auxiliary support plate 340. Alternatively, mounting grooves can be provided in the first auxiliary support plate 330 and second auxiliary support plate 340, with the magnetic field components disposed in the mounting grooves.
Referring to Figs. 1 and 10, in one embodiment, the storage body 100 is a refrigerator liner, which defines the storage space 101. During use, the storage space 101 has an opening facing the front of the storage body 100.
In one implementation of this embodiment, the magnetic field device 200 is disposed inside the storage space 101, and gaps exist between the magnetic field device 200 and two opposite inner side walls of the storage space 101, and two sides of the magnetic conductive plate 230 on which the first magnetic field generator 210 and the second magnetic field generator 220 are mounted face the two opposite inner side walls of the storage space having gaps with the magnetic field device 200. Specifically, gaps exist between the magnetic field device 200 and the opposite upper and lower inner side walls of the liner. The two sides of the magnetic conductive plate 230 on which the first magnetic field generator 210 and the second magnetic field generator 220 are mounted face the upper and lower inner side walls of the liner.
It should be noted that the storage space 101 defined by the liner can be a refrigerating chamber, variable temperature chamber, or freezing chamber.
Referring to Figs. 1 and 11, in one implementation of this embodiment, gaps exist between the magnetic field device 200 and the opposite left and right inner side walls of the liner. The two sides of the magnetic conductive plate 230 on which the first magnetic field generator 210 and the second magnetic field generator 220 are mounted face the left and right inner side walls of the liner.
Furthermore, a supporting component 300 is provided inside the liner, the supporting component 300 is plate-shaped and has an accommodation groove, and the magnetic field device 200 is disposed in the accommodation groove.
It should be noted that the supporting component 300 can also be a partition plate, with the magnetic field device 200 attached to the partition plate.
Specifically, when the storage body 100 is a liner, the installation method of the magnetic field device 200 can refer to the installation method when the storage body 100 is a drawer, meaning the construction of the supporting component 300 can reference the embodiments where the storage body 100 is a drawer.
It should be noted that the magnetic field device 200 can also be disposed on the inner side walls or outer side walls of the storage space 101. For example, it can be disposed on the outer side of the upper wall, left wall, right wall, or lower wall, or on the inner side of the upper wall, left wall, right wall, or lower wall.
As shown in Fig. 12, in one embodiment, the storage body 100 forms multiple storage spaces 101, with the magnetic field device 200 disposed between two storage spaces 101, and the surfaces of the magnetic conductive plate 230 on which the first magnetic field generator 210 and the second magnetic field generator 220 are mounted face the two storage spaces 101 respectively. Specifically, the storage body 100 can be a refrigerator cabinet, defining multiple compartments as storage spaces 101, such as a refrigerating chamber and a freezing chamber, or a refrigerating chamber and a variable temperature chamber. The magnetic field device 200 is disposed between two storage spaces 101, that is, in the foaming layer of the refrigerator cabinet. With the two storage spaces 101 distributed vertically, the sides of the magnetic conductive plate 230 on which the first magnetic field generator 210 and the second magnetic field generator 220 are mounted face the bottom of the upper storage space 101 and the top of the lower storage space 101 respectively.
By disposing the magnetic field device 200 between two storage spaces 101, the magnetic field device 200 can generate magnetic field effects for both storage spaces 101, improving the efficiency of the magnetic field device 200.
It should be noted that a single drawer or liner can also form multiple storage spaces.
Referring to Figs. 1 to 12, preferably, in one embodiment, the ratio of the area of projection of the first magnetic field generator 210 on a plane perpendicular to a center line of the first magnetic field generator 210 to the area of projection of the storage space 101 on the plane perpendicular to the center line of the first magnetic field generator 210 is 0.8.
Additionally, the ratio of the area of projection of the second magnetic field generator 220 on a plane perpendicular to a center line of the second magnetic field generator 220 to the area of projection of the storage space 101 on the plane perpendicular to the center line of the second magnetic field generator 220 is 0.8.
Specifically, referring to Fig. 12, the plane perpendicular to the center line of the first magnetic field generator 210 is the plane perpendicular to the vertical direction. Assuming a projection plane, if the projection area of the first magnetic field generator 210 on the projection plane is S1, and the projection area of the storage space 101 on the projection plane is S2, then S1=0.8S2. Similarly, if the projection area of the second magnetic field generator 220 on the projection plane is S3, and the projection area of the storage space 101 on the projection plane is S2, then S3=0.8S2.
It should be noted that the ratio of the area enclosed by the edges of the projection of the first magnetic field generator 210 on a plane perpendicular to a center line of the first magnetic field generator 210 to the area of projection of the storage space 101 on the plane perpendicular to the center line of the first magnetic field generator 210 can also be 0.3, 0.5, 0.6, 0.7, 1, 1.5, etc., as long as it is between 0.3 and 1.5.
Similarly, the ratio of the area enclosed by the edges of the projection of the second magnetic field generator 220 on a plane perpendicular to a center line of the second magnetic field generator 220 to the area of projection of the storage space 101 on the plane perpendicular to the center line of the second magnetic field generator 220 can also be 0.3, 0.5, 0.6, 0.7, 1, 1.5, etc., as long as it is between 0.3 and 1.5.
The projection area ratios between the two magnetic field generators and the storage space can be different.
By maintaining the ratio of the projection area of the first magnetic field generator 210 on a plane perpendicular to a center line of the first magnetic field generator 210 to the projection area of the storage space 101 on the plane perpendicular to the center line of the first magnetic field generator 210 between 0.3 and 1.5, it helps ensure the coverage effect of the magnetic field generated by the first magnetic field generator 210 within the storage space 101, guaranteeing the magnetic field's effect on food ingredients. Similarly, maintaining the ratio of the projection area of the second magnetic field generator 220 on a plane perpendicular to a center line of the second magnetic field generator 220 to the projection area of the storage space 101 on the plane perpendicular to the center line of the second magnetic field generator 220 between 0.3 and 1.5 helps ensure the coverage effect of the magnetic field generated by the second magnetic field generator 220 within the storage space 101, guaranteeing the magnetic field's effect on food ingredients.
As shown in Fig. 13, in one embodiment, the first magnetic field generator 210 and the second magnetic field generator 220 are electromagnetic coils. The two electromagnetic coils are attached to both sides of the magnetic conductive plate 230 respectively, generating magnetic fields when powered.
Specifically, referring to Figs. 14 to 22, when the first magnetic field generator 210 and the second magnetic field generator 220 are electromagnetic coils, the installation method of the magnetic field device 200 in the storage body is the same as when the first magnetic field generator 210 and the second magnetic field generator 220 are magnetic sheets, as described above, which will not be repeated here.
When the first magnetic field generator 210 and the second magnetic field generator 220 are electromagnetic coils, two magnetic poles of the first magnetic field generator 210 and two magnetic poles of the second magnetic field generator 220 are distributed in the same direction, and the distribution direction of the two magnetic poles of the first magnetic field generator 210 is perpendicular to the surface of the magnetic conductive plate 230 on which the first magnetic field generator 210 is mounted.
The magnetic field direction generated by the powered electromagnetic coils is distributed along their winding center lines, meaning the center line of the electromagnetic coil is perpendicular to the surface of the magnetic conductive plate 230 where the electromagnetic coil is mounted. Moreover, the current directions in the two electromagnetic coils are the same, ensuring that the distribution directions of the magnetic poles of the two electromagnetic coils are the same.
Additionally, preferably, the magnetic conductive plate 230 is made of a material having a relative magnetic permeability greater than 1, such as ferromagnetic material or permanent magnetic material. Here, relative magnetic permeability refers to the ratio of the material's magnetic permeability to vacuum magnetic permeability.
Referring to Figs. 14 and 22, in one embodiment, the ratio of the area enclosed by the edges of the projection of the first magnetic field generator 210 on a plane perpendicular to a center line of the first magnetic field generator 210 to the area of projection of the storage space 101 on the plane perpendicular to the center line of the first magnetic field generator 210 is 0.9.
Additionally, the ratio of the area enclosed by the edges of the projection of the second magnetic field generator 220 on a plane perpendicular to a center line of the second magnetic field generator 220 to the area of projection of the storage space 101 on the plane perpendicular to the center line of the second magnetic field generator 220 is 0.9.
Specifically, referring to Fig. 22, the plane perpendicular to the center line of the first magnetic field generator 210 is the plane perpendicular to the vertical direction. Since the first magnetic field generator 210 and the second magnetic field generator 220 are ring-shaped, the area enclosed by the edges of the projection of the first magnetic field generator 210 on a plane perpendicular to a center line of the first magnetic field generator 210 includes the area corresponding to the hollow portion in the middle of the ring. Assuming a projection plane, if the projection area of the first magnetic field generator 210 on the projection plane is S1 (including the area corresponding to the hollow portion of the ring), and the projection area of the storage space 101 on the projection plane is S2, then S1=0.9S2. If the projection area of the first magnetic field generator 210 on the projection plane is S3 (including the area corresponding to the hollow portion of the ring), and the projection area of the storage space 101 on the projection plane is S2, then S3=0.9S2.
It should be noted that the ratio of the area enclosed by the edges of the projection of the first magnetic field generator 210 on a plane perpendicular to a center line of the first magnetic field generator 210 to the area of projection of the storage space 101 on the plane perpendicular to the center line of the first magnetic field generator 210 can also be 0.5, 0.6, 0.7, 1, 1.5, etc., as long as it is between 0.5 and 1.5.
Similarly, the ratio of the area enclosed by the edges of the projection of the second magnetic field generator 220 on a plane perpendicular to a center line of the second magnetic field generator 220 to the area of projection of the storage space 101 on the plane perpendicular to the center line of the second magnetic field generator 220 can also be 0.5, 0.6, 0.7, 1, 1.5, etc., as long as it is between 0.5 and 1.5.
The projection area ratios between the two magnetic field generators and the storage space can be different.
It should be noted that because electromagnetic coils have hollow areas, their minimum ratio requirement needs to be greater than that of magnetic sheets.
As shown in Fig. 23, furthermore, taking the first magnetic field generator 210 as an example, the first terminal 211 and the second terminal 212 of the first magnetic field generator 210 are located at the same position, specifically, the position of the two terminals is less than or equal to 3 centimeters apart. This facilitates the positioning of the power supply. The winding method of the second magnetic field generator 220 is the same as that of the first magnetic field generator 210, and the terminals of the first magnetic field generator 210 and the second magnetic field generator 220 are located at corresponding positions on both sides of the magnetic conductive plate 230.
