In order to make the technical problems solved, the technical solutions adopted and the technical effects achieved by the present invention clearer, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the features relevant to the present invention are shown in the drawings.

Example one

Referring to fig. 1, an embodiment of the present invention provides a housing that can be used for a home appliance. The shell 1 is packaged with a pattern layer 2 through a glue film, the pattern layer 2 is formed by printing liquid metal on a flexible substrate 3, and the flexible substrate 3 is attached to the outer surface of the shell 1. Based on a liquid metal printing technology, the pattern layer 2 is printed on the flexible substrate 3, the flexible substrate 3 is pasted on the shell 1, and the flexible substrate is shaped and protected through a glue film, so that the pattern layer 2 has metal texture, good ductility, strong attaching force and low comprehensive cost; the arrangement of the adhesive film enables the flexible substrate 3 to be tightly attached to the shell 1, and plays a certain role in water resistance and corrosion resistance; in addition, the pattern layer 2 can be designed and customized in a personalized way, and the personalized requirements of users are met.

The liquid metal printing technology is to directly and rapidly manufacture a flexible and stretchable electronic circuit and a terminal functional device thereof through liquid metal electronic ink. Compared with the traditional rigid circuit board, the electronic ink has the advantages of good circuit ductility, strong attaching capability, simple production process, environmental-friendly and pollution-free manufacturing process, low comprehensive cost and the like, and the electronic ink material is safe, stable, nontoxic, recyclable and good in environmental-friendly performance.

The pattern layer 2 may be a text, a figure or a combination of the text and the figure, which is not limited herein and is set according to the requirement of the user. Due to the adoption of the liquid metal printing technology, the pattern layer 2 has better refinement level and vivid image.

The color of the pattern layer 2 is a metal natural color and has a metal texture. However, in order to diversify the pattern layer 2, a color layer may be provided on the pattern layer 2, the color layer being different from the natural color of the pattern layer 2. The color layer can be made of color-variable sensitive materials, and the color-variable sensitive materials can be one or more of photosensitive materials, humidity-sensitive materials and temperature-sensitive materials. The color of the color-changeable sensitive material can be changed between two or more of red, orange, yellow, green and the like, and is not limited herein.

The color layer can be fluorescent powder arranged on metal, and the fluorescent powder is attached to the metal when the liquid metal is in a molten state during liquid metal printing.

The surface of the pattern layer 2 can be etched to obtain the preset lines, so that the image of the pattern layer 2 is more vivid and better meets the individual requirements of users or the application scene of the shell 1.

In the present embodiment, the adhesive film is made of epoxy resin. The adhesive film may be transparent or colored, and is not limited herein.

In this embodiment, the flexible substrate 3 may be a silicon rubber or epoxy resin, or a plastic layer made of other synthetic resins, which is not limited herein. The flexible substrate 3 has low requirements on the shape of the housing 1, and the surface of the housing 1 may be a plane, a curved surface, or even a curved surface with an inward or outward protrusion, and is suitable for a wide range, which is not limited herein.

The shell 1 provided by the embodiment of the invention can be used for a water heater, a refrigerator, a washing machine or other products with shells, and the patterns of the shells need to be customized individually. For example, when the color layer is made of fluorescent powder, the case 1 can be used on a clock case, and at night, the fluorescent powder emits light, so that people can see the numbers on the clock, the electric energy is saved, and the clock case is safe and environment-friendly; or the fluorescent powder is used on the refrigerator shell, and at night, the fluorescent powder emits light, so that people can see the specific position of the refrigerator and can smoothly take food.

Example two

Fig. 2 shows a second embodiment, wherein the same or corresponding parts as in the first embodiment are provided with the same reference numerals as in the first embodiment. For the sake of simplicity, only the differences between the second embodiment and the first embodiment will be described. The difference is that the pattern layer 2 is a conductive circuit, because the pattern layer 2 is formed by adopting a liquid metal printing technology, the metal itself has conductivity, and the pattern layer 2 is arranged in a circuit form, namely the conductive circuit can be formed.

The conductive loop is provided with a plurality of luminous bodies, and the positive interface and the negative interface of the conductive loop are electrically connected with the electrical chamber 4 on the shell 1. After the power is switched on, the luminous body emits light, the effect of the pattern layer 2 is higher than that of the traditional printed pattern, and the pattern layer 2 can be set into various forms according to the personalized customization requirements of users, so long as short circuit and open circuit are avoided.

The conductive loop comprises a plurality of circuits, and the circuits can be connected in parallel, in series or in a combination of parallel connection and series connection. The arrangement form of the conductive loop is based on the premise that a plurality of luminous bodies are combined to form personalized patterns or characters.

The luminous body is the LED lamp, and the LED lamp plug is on conductive loop. When the liquid metal is printed, when the liquid metal is in a molten state, the LED lamp is inserted on the metal, the production process is simple, poor contact of the LED lamp is avoided, and the failure rate is reduced. The LED lamp may be one color or a plurality of colors, or may be a temperature-controlled LED lamp whose color changes with temperature, which is not limited herein.

The shape of the light-emitting body may be a sphere, a strip, a ring or a spiral, and may also be a leaf, a heart, a character or others customized by the user, which is not limited herein.

The embodiment of the invention also provides an electric water heater, which comprises the shell 1 of any embodiment. Because the pattern layer 2 on the shell 1 has various styles, the personalized customization requirement of a user can be met, and the electric water heater can be designed and customized in a personalized way.
