Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a visually levitating fan with lighting effects. Background Technology

[0002] To enhance the aesthetics and added value of their products, more and more electric fans are integrating lighting functions. However, in the pursuit of the ultimate visual levitation effect, how to introduce lighting without disrupting this levitation appearance is a challenge.

[0003] Existing visually floating fans, exemplified by CN 207847977U, create a basic floating visual effect by setting up transparent front and rear supports, but they do not integrate any lighting system. To simply add lighting to it, a light ring is usually set in the center of the front grille, but this requires running wires to the front grille, which inevitably destroys the clean, unconnected "floating" feeling in front.

[0004] Therefore, existing technologies lack a solution that can seamlessly integrate a lighting system into a suspended fan structure without compromising its core visual effect. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a visually floating fan that achieves a uniform and soft lighting effect in front without introducing a forward wire, perfectly maintaining the visual appearance of the fan floating.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A visually levitating fan with lighting effects includes a fan assembly, a front grille assembly, and a rear grille assembly. The fan assembly includes a fan motor and an impeller driven by the fan motor. The front grille assembly and the rear grille assembly together surround the fan assembly. The rear grille assembly includes a rear grille and a transparent rear grille support member. The front grille assembly includes a front grille and a transparent front grille support member, wherein: The transparent support for the rear mesh is a disc-shaped transparent part that is polished as a whole. It has a disc bottom, a disc wall extending from the disc bottom and a central through hole. The disc wall forms a light-reflecting surface. A light panel is fixedly installed at the center through hole of the transparent support member of the rear mesh, and the light emission direction of the lamp beads installed on the light panel is towards the disk wall; The front grille assembly also includes a ring-shaped lampshade, which is arranged around the center of the front grille; The light emitted by the lamp beads is reflected by the disc wall of the rear transparent support member, changes the light path and shines forward, passing through the transparent area of ​​the impeller and the front transparent support member in sequence, and finally reaches and illuminates the lamp cover.

[0007] Furthermore: The disc wall of the transparent rear support is inclined or curved and is polished to reflect radially incident light into light that is generally axially forward.

[0008] The impeller includes a transparent ring located around its rotation center. The transparent support member of the rear net, the transparent ring of the impeller, and the transparent support member of the front net are aligned in the front-to-back direction to form a light transmission channel for reflected light to pass through.

[0009] The power supply line of the lamp panel extends rearward, passes through the rear mesh assembly, and connects to the control circuit board.

[0010] The lampshade is made of a semi-transparent or diffused material to diffuse the incoming light and form a uniform surface light source.

[0011] The outer edge of the transparent support member of the rear net is embedded and fixed to the outer periphery of the central through hole of the rear net; the outer edge of the transparent support member of the front net is embedded and fixed to the outer periphery of the central through hole of the front net.

[0012] The fan assembly also includes a motor bracket, on which the light panel and the fan motor are mounted. The motor bracket passes through the central through hole of the transparent support member of the rear mesh and is fixed to the rear mesh bracket of the rear mesh assembly.

[0013] The impeller has a central groove, and the fan motor is completely housed within the central groove of the impeller.

[0014] It also includes a main unit assembly for supporting the fan, which includes a housing and a battery module, an oscillating motor, and a control circuit board disposed within the housing.

[0015] The beneficial effects of this utility model are as follows: 1. Achieved true wire-free lighting: Through an original reflective light path design that emits light from the rear and develops it from the front, the wires in the front mesh section are completely eliminated, ensuring the integrity and purity of the suspended visual effect.

[0016] 2. Uniform and soft light effect: The light is reflected, penetrates multiple layers of transparent parts, and is finally diffused by the diffuser, eliminating the harshness of LED point light sources and forming a high-end uniform surface light, which enhances the product's texture.

[0017] 3. Compact structure and reusable functions: Key components such as the transparent support for the rear mesh simultaneously serve the dual functions of structural support and optical path guidance, achieving deep integration of the optical system and mechanical structure. This eliminates the need for additional complex light guides, simplifying the structure and reducing costs.

[0018] 4. Enhanced the overall aesthetics and technological feel of the product: The lighting and the floating visual effect complement each other. In the dark, the glowing ring-shaped front grille and the seemingly floating fan blades combine to create a visually stunning experience that is both futuristic and technologically advanced.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 9 As shown, the visual levitation fan embodiment of this utility model includes four main modules: a main unit assembly 100, a rear grille assembly 200, a fan assembly 300, and a front grille assembly 400. The fan assembly 300 includes a fan motor 330 and an impeller 340 driven by the fan motor 330. The front grille assembly 400 and the rear grille assembly 200 together surround the fan assembly 300.

[0022] The rear net assembly 200 includes a rear net 220 and a transparent support member 230 fixedly disposed within a central through-hole 221 of the rear net. The transparent support member 230 has a central through-hole 231. In some embodiments, the rear net assembly 200 further includes a rear net bracket 210, which is fixedly connected to a motor bracket 310. The motor bracket 310 of the fan motor passes through the central through-hole 231 of the transparent support member and is fixedly connected to the rear net assembly 200.

[0023] The impeller 340 includes a central groove 341 for accommodating the fan motor 330, a transparent ring 342 located around the central groove, and a fan blade 343 located around the transparent ring; the central groove 341 of the impeller is sleeved outside the fan motor 330.

[0024] The front mesh assembly 400 includes a front mesh 410 and a transparent support member 440 fixedly disposed within the central through-hole 411 of the front mesh. The front mesh assembly 400 also includes a decorative cover 430 for closing the central through-hole 441 of the transparent support member 440, the decorative cover 430 shielding the central groove 341 of the impeller 340 from the front. The front mesh assembly 400 also includes an annular lampshade 420, the lampshade 420 being disposed around the central through-hole 411 of the front mesh 410 for receiving and diffusing light incident from the rear.

[0025] like Figure 7 and Figure 9 As shown, the transparent support member 230 of the rear net is a transparent disc-shaped component that has been polished as a whole. It includes a disc bottom 232 and a disc wall 233 extending from the disc bottom. The disc wall is processed into a polished bevel to form a light-reflecting surface. The transparent support member 230 of the rear net can be a one-piece molded component made of a transparent material such as polycarbonate (PC) or acrylic (PMMA).

[0026] like Figures 4 to 9 As shown, it also includes a light panel 320, which has a plurality of LED beads 321 arranged around it. The LED beads 321 on the light panel 320 face outwards and are directly opposite the disk wall 233.

[0027] During assembly, the transparent support member 230 of the rear net is embedded into the central through hole 221 of the rear net 220, and then the motor bracket 310 is passed through the central through hole 231 of the transparent support member 230 of the rear net. The motor bracket 310 and the rear net bracket 210 are fixedly connected by screws or other means.

[0028] Next, the lamp panel 320 and the fan motor 330 are mounted on the motor bracket 310, and the central groove 341 of the impeller 340 is fitted over the fan motor 330, so that the fan motor 330 is completely contained within the central groove 341 of the impeller 340. The transparent ring 342 of the impeller 340 faces the transparent support member 230 of the rear mesh in the front-to-back direction, together forming a light transmission channel.

[0029] Next, assemble the front mesh assembly 400, insert the transparent front mesh support 440 into the central through hole 411 of the front mesh 410, and install the annular lampshade 420 on the front mesh 410. Finally, align and fasten the entire front mesh assembly 400 with the rear mesh assembly 200, securing it with latches or similar means. At this point, the transparent front mesh support 440 faces the transparent ring 342 of the impeller in the front-to-back direction. The decorative cover 430 closes the central hole 441 of the transparent front mesh support 440 from the front and covers the central groove 341 of the impeller.

[0030] The transparent rear support 230, the transparent impeller ring 342, and the transparent front support 440 together form a seamless and continuous transparent visual area. During operation, the impeller 340 rotates at high speed, but the motor 330 at its center is completely hidden, and the rotational dynamics of the transparent ring 342 are not easily detected, making the outer fan blades 343 and the front and rear screens appear to be suspended in the air.

[0031] Because the rear transparent support 230 is polished as a whole, the radial light emitted by the LED beads 321 on the light panel 320 experiences minimal loss when passing through the bottom 232 of the disk. When the light hits the reflective slope of the disk wall 233, the light path is altered, allowing it to shine forward. The light passes sequentially through the transparent ring 342 and the front transparent support 440, and is finally evenly diffused by the front lampshade 420. The front lampshade 420 can be made of a milky white PC or PS light-diffusing material, which disperses the gathered light, forming a very uniform ring-shaped light-emitting band, creating a soft halo with a highly decorative effect.

[0032] By cleverly fixing the light panel 320 to the central through hole of the transparent support member 230 of the rear grille, the power supply wire W of the light panel 320 can be connected to the control circuit board through the rear grille bracket. The light of the lampshade 420 surrounding the central through hole of the front grille comes from the illumination of the rear light panel. Therefore, the front lampshade does not need to be connected with wires. While satisfying the visual effect of the fan floating, it also has the effect of lighting decoration, realizing the ideal effect of front grille lighting without front grille wiring.

[0033] This invention designs an integrated reflective optical path system, achieving deep integration of optical and structural elements. In the rear mesh assembly, the transparent support component serves a dual function: firstly, as a structural component supporting parts such as the motor bracket; secondly, as a core optical element, it is entirely polished and features a specially designed reflective disk wall. A lamp plate is fixed at the central through-hole of the transparent support component, with LED beads emitting radially outward light that directly illuminates the reflective disk wall. Because the reflective disk wall is polished and has a specific angled or curved surface, the light undergoes total internal reflection or specular reflection, altering the optical path from radial propagation to approximately forward (axial) propagation. The forward-propagating light passes sequentially through the transparent ring of the impeller and the transparent support component of the front mesh, ultimately reaching and illuminating the annular lampshade on the front mesh assembly. This lampshade, made of a semi-transparent or diffuser material, further diffuses the light, forming a uniform and soft annular halo.

[0034] Thus, the light source (light panel) was successfully placed at the rear, while the luminous effect (lampshade) was presented at the front. All power lines were connected from the rear, and no wires were needed in the front luminous area, thereby completely solving the problem of the lighting system destroying the floating visual effect.

[0035] like Figure 1 , Figure 3 and Figure 5 As shown, the system also includes a main unit assembly 100 for supporting the fan. The main unit assembly 100 includes an upper shell 111, a lower shell 112, a battery 120, an oscillating motor 130, a main control board 140, an oscillating rotation bracket 150, and a base 160. The upper shell 111 and lower shell 112 are combined to form a housing, and the battery 120, oscillating motor 130, main control board 140, and oscillating rotation bracket 150 are all housed within the housing. The oscillating motor 130 drives the oscillating rotation bracket 150 to rotate, thereby causing the housing to rotate relative to the base.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
