Description

Technical Field

[0001] This utility model relates to the field of LED advertising technology, and in particular to a magnetic LED advertising device. Background Technology

[0002] In the context of the integration of the modern hotel service industry and smart home devices, the refrigerator, as an essential appliance in guest rooms, has expanded its function beyond traditional food storage and preservation. With consumers increasingly demanding personalized and differentiated accommodation experiences, hotel managers and smart appliance manufacturers are constantly exploring how to enhance the attractiveness and interactivity of guest rooms through innovative design, thereby increasing customer satisfaction and brand loyalty.

[0003] Traditional refrigerator designs often prioritize practicality and energy efficiency, neglecting their potential in creating a welcoming atmosphere and conveying cultural information. This is especially true in the hotel industry, where each hotel possesses its own unique cultural characteristics and regional charm. The key to enhancing the stay experience lies in skillfully integrating these elements into guest room facilities. Furthermore, different cities, as tourist destinations, boast rich historical sites, folk customs, and culinary specialties, all of which are highly attractive to tourists and serve as vital resources for hotels to showcase their unique features and attract customers.

[0004] Against this backdrop, applying replaceable independent light-up sign technology to refrigerator doors has become an innovative solution. This design not only retains the basic functions of the refrigerator but also allows for dynamic display of different city characteristics and hotel culture through flexible light-up sign replacement. As a medium for information transmission, the light-up signs can take various forms, such as LED displays, e-ink screens, or traditional light boxes. The content can be changed at any time according to the hotel's needs, seasonal changes, festivals, and other factors, such as city scenery, hotel history, and featured dish recommendations, adding a touch of cultural atmosphere and interactive fun to the guest rooms.

[0009] Furthermore, the door is provided with an annular groove, and an annular rubber ring is fixed on the cover plate, the annular rubber ring being slidably connected in the annular groove.

[0010] Furthermore, it also includes a limiting plate, which abuts against the cover plate to limit the position of the advertising paper.

[0011] Furthermore, the limiting plate is provided with four through holes, and the magnetic suction column is movably arranged through the through holes.

[0012] Furthermore, a light-transmitting hole is provided through the middle of the limiting plate, through which the LED beads can pass.

[0013] Furthermore, a slot is provided through the limiting plate, and the slot is positioned opposite to the display screen and the glass window.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model features a replaceable, independent light board mounted on the refrigerator door, which can be used to display and promote the characteristics of different cities and the culture of different hotels. The cover is installed using a magnetic attachment, making it easy to replace the advertising paper. The operation is simple and convenient. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a magnetic LED advertising device, including:

[0022] Refrigerator 1, with a door 2 movably connected to it;

[0023] Magnetic LED advertising component; The magnetic LED advertising component includes a groove 3 on the door 2, the groove 3 is sealed by a cover plate 8, the door 2 is provided with an annular groove 7, and an annular rubber ring 17 is fixed on the cover plate 8. The annular rubber ring 17 is slidably connected in the annular groove 7, so as to seal the groove 3 and prevent dust and other objects from entering the groove 3.

[0024] The door 2 is provided with multiple heat dissipation slots that communicate with the groove 3 and the outside. Dust filters are installed in the heat dissipation slots, and small cooling fans can also be installed to dissipate heat from the internal LED beads 5 and display screen 6.

[0025] LED beads 5 and a display screen 6 are installed in the groove 3. The LED beads 5 and display screen 6 can be powered independently, such as by installing a separate rechargeable power supply. They can also be connected in series with the refrigerator 1; when the refrigerator 1 is powered, the LED beads 5 and display screen 6 are also powered. A light-transmitting hole 14 is provided through the center of the limiting plate 11, allowing the LED beads 5 to pass through and illuminate the advertising paper, making it glow. This can be used to display and promote the characteristics of different cities and the culture of different hotels. The advertising paper can be replaced to suit different environments.

[0026] The display screen 6 is used to display the temperature and humidity inside the refrigerator 1, and needs to be connected to the temperature and humidity sensor inside the refrigerator (radar and infrared sensing technology can also be used, which lights up when someone is present, saving power and making it more user-friendly; this part is existing technology).

[0027] A glass plate 9 and a glass window 10 opposite to the display screen 6 are installed through the cover plate 8. The display screen 6 can be observed through the glass window 10. A slot 12 is provided through the limiting plate 11. The slot 12 is set opposite to the display screen 6 and the glass window 10.

[0028] A placement groove 16 is formed between the glass plate 9 and the cover plate 8. The placement groove 16 is used to place advertising paper. It also includes a limiting plate 11. The limiting plate 11 abuts against the cover plate 8 to limit the advertising paper. Four through holes 13 are provided on the limiting plate 11. The magnetic column 15 is movably arranged through the through holes 13. The inner diameter of the through hole 13 is smaller than the outer diameter of the sleeve 4. Therefore, the limiting plate 11 is supported by the sleeve 4.

[0029] Four sleeves 4 are fixed inside the groove 3, and magnetic blocks 18 are fixed inside the sleeves 4. Four magnetic posts 15 are fixed on the cover plate 8. When the magnetic posts 15 abut against the magnetic blocks 18 and are located inside the sleeves 4, the cover plate 8 seals the groove 3, thus realizing the installation of the cover plate 8. When changing the advertising paper, the cover plate 8 can be pulled from the side or the cover plate 8 can be removed by using the rubber suction cup to suction the posts. The operation is simple and convenient.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
