Description

Technical Field

[0001] This utility model relates to the field of magnetic development technology, specifically to a display device capable of developing reflective color-changing properties. Background Technology

[0002] Dynamic magnetic field line display devices can use the attraction of magnetic poles to magnetic powder to make the magnetic powder change into various shapes for users to view. Magnetic powder is usually filled in the developing device. By using the changes in magnets and magnetic fields, the magnetic powder is controlled to form different shapes inside the developing device. Different patterns can be formed by observing the density of the magnetic powder.

[0003] Conventionally, magnetic powder is placed inside the casing. When it is near an external magnetic field, the magnetic powder will move and solidify, and then the magnetic lines of force will be developed. During the research and development process, the applicant found that due to the influence of the particle size of the magnetic powder, the magnetic field is difficult to move the magnetic powder quickly, and the development speed is slow. As a result, the dynamic development effect is poor, and the development effect is reduced. Therefore, we propose a development-reflective color-changing display device. Summary of the Invention

[0004] To address the shortcomings of existing reflective color-changing display devices, this invention provides a reflective color-changing display device that uses iron powder instead of magnetic powder, with a particle size of 800 mesh. The magnetic field drives the iron powder to flow faster, resulting in a faster development speed and a more significant dynamic development effect. In addition, the iron powder is coated with a chameleon coating, which improves the visual appeal. This invention solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a reflective and color-changing display device, comprising a lower cover plate, an upper cover plate, and iron powder. The lower cover plate and the upper cover plate are sealed together and assembled into a whole with a cavity. The iron powder is uniformly filled into the cavity formed by the lower cover plate and the upper cover plate. At the same time, the lower cover plate and the upper cover plate are filled with mineral oil. The iron powder is immersed in the mineral oil and flows freely in the cavity. The particle size of the iron powder is 800 mesh.

[0006] Preferably, the iron powder is coated with a chameleon material to achieve reflective color-changing properties, and the chameleon material is used to provide the iron powder to display the desired target color.

[0007] Preferably, the mineral oil is an emulsified oil.

[0008] Preferably, the front portions of both the lower and upper cover plates, excluding the frame, are made of transparent material.

[0009] Compared with existing reflective color-changing display devices, this invention has the following advantages: This reflective and color-changing display device fills the interior of the lower and upper cover plates with 800-mesh iron powder, which is mixed with mineral oil and filled into the cavity inside the lower and upper cover plates. The 800-mesh iron powder can flow faster under the action of an external magnetic field, thus developing the image more quickly and improving the visual effect of dynamic development. At the same time, the iron powder is coated with chameleon paint, which can provide different colors for viewing, improve the visual experience, and meet the color needs of different people.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1 , Figure 2 and Figure 3 A reflective color-changing display device includes a lower cover plate 1, an upper cover plate 2, and iron powder 3. The lower cover plate 1 and the upper cover plate 2 are sealed together and assembled into a whole, which facilitates the filling of iron powder 3 and avoids leakage during use. The iron powder 3 is evenly filled into the cavity formed by the lower cover plate 1 and the upper cover plate 2. At the same time, the lower cover plate 1 and the upper cover plate 2 are filled with mineral oil. After the mineral oil is mixed with the iron powder 3, the iron powder is soaked in the mineral oil and flows freely in the cavity, which improves the flow effect of iron powder 3 in the lower cover plate 1 and the upper cover plate 2.

[0014] Please see Figure 3 The iron powder 3 has an 800-mesh particle size and is coated with a chameleon coating. By designing the iron powder 3 to have an 800-mesh particle size, it can flow faster under the influence of an external magnetic field, thus developing faster and improving the visual effect of dynamic development. At the same time, the chameleon coating on the outside of the iron powder 3 can improve the viewing experience. The color of the chameleon coating can be adjusted according to different usage needs to ensure viewing comfort.

[0015] Please see Figure 3 The mineral oil is an emulsified oil. After the iron powder 3 is mixed with the emulsified oil, it is filled into the cavity formed inside the lower cover plate 1 and the upper cover plate 2. The cavity formed inside the lower cover plate 1 and the upper cover plate 2 is filled with emulsified oil and iron powder 3. The iron powder 3 and the emulsified oil are mixed with each other, which improves the suspension state of the iron powder 3 inside the lower cover plate 1 and ensures that the iron powder 3 is conveyed when it flows. When the magnetic poles are in contact, under the action of the magnetic field, it ensures the convenience of the iron powder 3 when it moves inside the cavity formed inside the lower cover plate 1 and the upper cover plate 2.

[0016] Please see Figure 1 The lower cover plate 1 and the upper cover plate 2 are fixed by ultrasonic welding. By using ultrasonic welding, the lower cover plate 1 and the upper cover plate 2 are welded together, which improves the sealing effect after the joint and ensures that the lower cover plate 1 and the upper cover plate 2 are tightly integrated after welding.

[0017] Please see Figure 1 The front of the upper cover plate 2 is made of transparent material. Because the upper cover plate 2 is made of transparent material, when the iron powder 3 is moved inside the lower cover plate 1 and the upper cover plate 2 by the magnetic pole, the image and effect of the movement of the iron powder 3 inside the cavity can be observed in time through the upper cover plate 2.

[0018] In use, the exterior of the iron powder 3 is coated with chameleon paint, and the iron powder 3 is mixed with a suspension. The mixed suspension is then filled into the cavity formed inside the lower cover plate 1 and the upper cover plate 2 to remove air from the cavity. The lower cover plate 1 and the upper cover plate 2 are fixed by ultrasonic welding to ensure the airtightness of the encapsulation. A magnetic pole is placed at the rear end of the lower cover plate 1. The iron powder 3 filled inside the lower cover plate 1 and the upper cover plate 2 is displaced under the action of the magnetic field. By observing the different displacement positions, the magnetic field pattern can be observed. The chameleon reflective material enhances visual recognition and added value, thus achieving a developing effect. The mixture of suspension and iron powder 3 ensures the flexibility of the iron powder 3 when moving within the cavity of the lower cover plate 1 and the iron powder 3.

[0019] Application examples and scenario examples: After this product is applied to the surface of various magnets, the iron powder 3 is shaped by the magnetic field and follows the shape of the magnetic field lines. The shape characteristics of the magnetic field lines can be observed by looking at the edge shape where the filling and hollowing of the iron powder 3 meet after shaping. Alternatively, this product can be applied to the surface of non-transparent objects containing magnetic fields, such as mobile phones, to visualize the distribution of the magnetic field within the non-transparent object. It can also be used to visualize the combined magnetic field when multiple magnets are placed together.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
