Description

Technical Field

[0001] The utility model relates to the technical field of magnetic fresh-keeping refrigerators, and in particular to a magnetic field explicitation device based on magnetic fresh-keeping refrigerators. Background Art

[0002] The refrigerator magnetic preservation technology is to configure a magnetic field generating module inside the refrigerator to form a uniform and constant magnetic field environment. Under the magnetic field of appropriate intensity, the molecular motion state of the food is frozen, showing an orderly and low-speed motion arrangement state, so that the food enters a dormant state, thereby slowing down the metabolic rate of nutrients, prolonging the freshness and decay cycle of the food, and locking in nutrition and flavor. However, the magnetic field is composed of moving tiny particles, which are invisible and intangible under current conditions. Therefore, for users who use refrigerators with magnetic preservation technology, it is not possible to intuitively feel whether there is a magnetic field in the magnetic preservation room, nor can it be detected whether the magnetic preservation function is working normally.

[0003] In view of this, it is necessary to improve the existing technology. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The preferred embodiment of the utility model provides a magnetic field visualization device based on a magnetic fresh-keeping refrigerator, through which it is possible to intuitively feel whether a magnetic field exists.

[0022] like Figure 1As shown, the visualization device includes a transparent sealed container 1, which is made of glass. A containing cavity is provided in the transparent sealed container 1, and the containing cavity is filled with a magnetic fluid, which is a mixture of a base carrier liquid, magnetic solid particles and a surfactant.

[0023] The base carrier liquid is water, organic solvent or oil, which is used to carry magnetic solid particles. The diameter of the magnetic solid particles is less than ten nanometers, and the material is iron, nickel or cobalt. The surfactant is oleic acid, which is used to prevent the magnetic solid particles from agglomerating.

[0024] Furthermore, a through hole communicating with the accommodating cavity is provided on the top of the transparent sealed container 1 , and a sealing plug 2 is detachably provided in the through hole, and magnetic fluid can be added into the transparent sealed container 1 through the through hole.

[0025] like Figure 2 As shown, a magnetic fresh-keeping compartment 3 is provided in the magnetic fresh-keeping refrigerator, and the visible device is installed in the fresh-keeping compartment 3. Specifically, a mounting groove is provided on the side wall of the magnetic fresh-keeping compartment 3, and the transparent sealed container 1 is embedded in the mounting groove. If a drawer is provided in the magnetic fresh-keeping compartment 3, the transparent sealed container 1 is installed on the front panel of the drawer.

[0026] The display device is placed in a non-magnetic field environment. Due to the thermal motion of nano-scale magnetic solid particles, it is difficult for the magnetic solid particles to be arranged uniformly, and they generally appear in the shape of water drops. When there is a magnetic field around, the magnetic solid particles will present a spike-like structure under the combined action of gravity, surface tension and magnetic attraction. Users can confirm whether there is a magnetic field in the refrigerator's magnetic preservation compartment by observing the changes in the morphology of the magnetic solid particles.

[0027] In summary, the magnetic field visualization device based on the magnetic fresh-keeping refrigerator described in the embodiment of the utility model allows users to easily perceive whether the magnetic field in the refrigerator with magnetic fresh-keeping function is real, and can be combined with colored magnetic fluid to create a unique visual effect and enhance the attractiveness of the product. In addition, the device has a simple structure, a variety of installation methods, small space occupation, and does not require any other equipment to drive.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
