Description

Technical Field

[0001] This utility model relates to a floor fan, and more particularly to a floor fan with a dynamic starry sky projection decoration section. Furthermore, it provides a technical solution for achieving a dynamic starry sky decoration effect by combining a projection device with a fan structure. Background Technology

[0002] Floor fans, a common household ventilation device, typically consist of basic components such as a base, pole, main body, and fan head. The main body integrates a controller, control panel, and motor drive system for adjusting functions such as wind speed and oscillation mode. The fan head, driven by a motor, rotates the fan blades to generate airflow for air circulation and cooling. With the increasing demand for home décor and multifunctional appliances, floor fans have gradually incorporated additional functions such as lighting and decoration while maintaining their basic fan function.

[0003] In existing technologies, there are several designs that combine light-emitting functionality with fan structure. For example, Chinese utility model patent CN 203835753 U discloses a "fan with light-emitting function." This patent includes fan blades, a fan blade drive motor, and a ring-shaped lampshade. The fan blades are disposed within the central space formed by the ring-shaped lampshade. The ring-shaped lampshade has an internal cavity, with its outer or front side wall being a light-transmitting element, and a light-emitting element is disposed within the internal cavity. This structure allows the ring-shaped lampshade to simultaneously serve as an air guide shell and a light-emitting cover, achieving the integration of fan operation and light emission, resulting in a relatively compact overall structure. Furthermore, the patent further optimizes details such as the air guide, support frame, and air vents to improve heat dissipation and light distribution.

[0004] Another Chinese utility model patent, CN 207795619 U, proposes a "portable fan with colored light," whose colored light generating device includes a brushless motor, a fan blade assembly, and a light-emitting panel. The fan blade assembly, made of a light-guiding material, is located at the front end of the brushless motor, while the light-emitting panel is located at the rear end of the motor, with light illuminating the fan blade assembly. During rotation, the fan blades diffuse and render the light emitted by the LED light source, creating a uniform and varied colored light effect. This design enhances the visual dynamics of the light and is suitable for decorative purposes and nighttime use with portable fans.

[0005] However, most existing light-up fans can only provide simple static colored light or basic color changes, with relatively simple light-up modes and a lack of dynamic and immersive visual experience. Utility Model Content

[0006] In view of the above-mentioned shortcomings in the existing technology, this utility model aims to solve the technical problems existing in current fans with light-emitting functions. This utility model mainly solves the problem of how to integrate a decorative system capable of projecting specific dynamic patterns (such as starry sky) onto a fan, thereby providing a new type of floor fan that integrates air delivery and high-end dynamic visual decoration.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a floor fan with a dynamic starry sky projection decoration part, comprising a base, a column, a main body, and a fan head arranged sequentially from bottom to top, wherein a control circuit is provided inside the main body, and a dynamic projection decoration part is also provided on the main body, the dynamic projection decoration part comprising:

[0008] The casing, whose shape forms the visual decorative center of the floor fan;

[0009] A light-emitting module is disposed within the housing, and the light-emitting module includes multiple LEDs capable of emitting various colors and dynamically changing controllable;

[0010] A projection module is positioned in front of the light-emitting module's optical path and has a preset hollow or light-transmitting pattern on it.

[0011] The dynamically changing light emitted by the light-emitting module is projected through the projection module, projecting the preset pattern in the form of dynamic light and shadow, thus creating a decorative light and shadow effect.

[0012] A further preferred embodiment of this utility model is that the dynamic projection decorative part is disposed on the top of the main body, located on the lower side of the fan head.

[0013] A further preferred embodiment of this invention is that the multiple LEDs of the light-emitting module are configured to emit light in a manner of color gradient and / or brightness gradient.

[0014] A further preferred embodiment of this utility model is: the projection module includes a projection sheet that carries the preset pattern, and a support structure for fixing and supporting the projection sheet;

[0015] The shell is planet-shaped, and the preset pattern projected by the projection module is a starry sky pattern.

[0016] Another topic: A floor fan with a dynamic starry sky projection decoration, comprising a base, a column, a main body and a fan head arranged from bottom to top, wherein the main body includes a control unit with an operation panel and control circuit, and a planet-shaped dynamic projection decoration is installed at the upper end of the control unit;

[0017] The dynamic projection decoration part includes:

[0018] The lower cover and the ring-shaped upper cover combine to form the basic shape of a planet-like structure.

[0019] A light source is disposed within the space enclosed by the lower cover and the annular upper cover. The light source includes a circuit board and multiple LEDs disposed on the circuit board that can emit different colors.

[0020] A light-transmitting ring is fixed between the lower cover and the annular upper cover, forming the planet's "star ring";

[0021] A projection paper with a starry sky pattern is placed in the light path above the light source;

[0022] A hemispherical projection dome is placed over the annular cover to form the hemispherical surface of the planet.

[0023] The LED lights are controlled by the control circuit to gradually brighten in turn. The light passes through the light-transmitting ring to form a luminous star ring, and shines on the projection paper to dynamically project the starry sky pattern onto the hemispherical projection dome, thus creating a dynamic visual effect of planets and stars.

[0024] A further preferred embodiment of this utility model is that the light-transmitting ring is made of a frosted, semi-transparent light-guiding material;

[0025] The projection paper is pressed and fixed on the inner step of the annular cover by a support ring.

[0026] A further preferred embodiment of this invention is that the inner wall of the lower cover and / or the annular upper cover is provided with a reflective layer.

[0027] A further preferred embodiment of this invention is that the control circuit is configured to receive signals from the operation panel or remote controller to switch between different light-emitting modes.

[0028] Another technical topic: A dynamic starry sky projection decorative part, comprising: a lower cover and an annular upper cover, wherein the lower cover and the annular upper cover are detachably fixedly connected to form a planet-shaped sealed shell;

[0029] A light source is fixedly installed on the inner side of the lower cover. The light source includes a circuit board and multiple LEDs that can emit light of different colors.

[0030] The light-transmitting ring is clamped and fixed in the annular groove formed at the junction of the lower cover and the annular upper cover;

[0031] A pattern projection module is disposed on the inner side of the annular top cover and located above the light path of the light source, and a starry sky pattern is formed on the pattern projection module;

[0032] A hemispherical projection cover covers the top opening of the annular cover;

[0033] The light emitted by the light source is configured such that: a portion of the light shines laterally and passes through the light-transmitting ring to form a surrounding star ring light effect; another portion of the light shines upward, passes through the star pattern on the pattern projection module, and projects the pattern onto the inner surface of the hemispherical projection cover.

[0034] Furthermore, the multiple LED lights are controlled to emit light in a gradually changing manner, thereby creating a dynamic starry sky projection effect on the hemispherical projection dome.

[0035] A further preferred embodiment of this invention is that the light-transmitting ring is made of a frosted, semi-transparent light-guiding material.

[0036] Compared with the existing technology, the advantages of this utility model are: by setting an LED light source that can emit multiple colors and gradually change light in turn, and combining it with a projection module with a starry sky pattern, a dynamic starry sky image with continuously and gently changing colors and brightness is successfully projected on a hemispherical projection dome, creating a visual atmosphere with a strong sense of immersion and artistic beauty, which significantly surpasses the single effect of traditional static lighting.

[0037] Furthermore, through ingenious optical path and structural design, a single light source simultaneously achieves two independent decorative lighting effects. One portion of the light penetrates horizontally through the translucent light ring, forming a uniform and continuous encircling "star ring" light band; the other portion projects upwards, clearly displaying the intricate starry sky pattern on the spherical dome. The "star ring" and the "starry sky" complement each other, together forming a complete and three-dimensional visual model of a planet, resulting in a richer and more realistic decorative effect.

[0038] Furthermore, the entire decorative section integrates the light source, light-transmitting components, projection components, and projection cover through the cooperation of the lower cover and the ring-shaped upper cover, forming a compact and well-sealed independent functional module. This modular design not only facilitates independent production, testing, and assembly, but also allows it to be flexibly adapted to various products (such as floor fans, table fans, ceiling fans, or as an independent decorative light), greatly enhancing the product's versatility and market application potential.

[0039] Furthermore, the elegant planetary shape is itself a sophisticated visual decorative element. Through precise internal optical design, the harsh point LED light source is transformed into soft, uniform diffused light and clear projection, eliminating any sense of cheapness and presenting an overall high-end, exquisite craftsmanship that satisfies users' higher pursuit of home aesthetics.

[0050] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0051] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0052] like Figures 1 to 2 As shown, this embodiment provides a floor fan 100 with a dynamic starry sky projection decoration part, including a base 101, a column 102, a main body 103, and a fan head 104 arranged sequentially from bottom to top. The main body 103 has a control circuit inside and an operation panel 107 formed on its outer side. A planet-shaped dynamic projection decoration part 105 is fixedly installed on the upper end of the main body 103 to achieve a dynamic starry sky light and shadow decoration effect.

[0053] like Figures 3 to 9 As shown, the dynamic projection decoration part 105 includes a lower cover 10 and an annular upper cover 20, a light source 30, a light-transmitting lamp ring 40, projection paper 50 (pattern projection module), and a hemispherical projection cover 60.

[0054] The lower cover 10 and the annular upper cover 20 are interlocked and fixedly connected, forming a planet-shaped shell. The joint between the two forms an annular groove for mounting the light-transmitting lamp ring 40. Reflective layers are provided on the inner walls of the lower cover 10 and the annular upper cover 20 to enhance the reflection of internal light.

[0055] The light source 30 is disposed within the space enclosed by the lower cover 10 and the annular upper cover 20, specifically including a circuit board 31 fixed inside the lower cover 10, and multiple LED lights 32 mounted on the circuit board 31. The LED lights 32 can emit light of different colors and achieve color gradient or brightness gradient under the drive of the control circuit.

[0056] The light-transmitting ring 40 is clamped and fixed in the annular groove at the junction of the lower cover 10 and the annular upper cover 20. The light-transmitting ring 40 is used to receive the light emitted laterally from the LED lamp 32 and form a uniform annular light band.

[0057] The projection paper 50 is positioned in the light path above the light source 30, and has a starry sky pattern engraved or cut out on it, including star points, nebulae, or linear textures. The outer edge of the projection paper 50 is pressed and fixed to the step inside the annular cover 20 by a support ring, so that the projection paper is stably and reliably arranged in the light path, avoiding displacement or deformation caused by vibration during use.

[0058] A hemispherical projection dome 60 is positioned over the upper opening of the annular cover 20. Made of transparent or semi-transparent material, the hemispherical projection dome 60 serves as the final display medium for the starry sky pattern. When light passes through the projection paper 50 and strikes the hemispherical projection dome 60, a dynamic starry sky pattern is formed on its inner surface.

[0059] When the user triggers the dynamic projection mode via the operation panel 107 or remote control, the control circuit sends a drive signal to the light source 30, causing multiple LEDs 32 to light up, change color, or change brightness in sequence according to a preset gradient logic.

[0060] A ring of light is formed under the horizontal light path. The light emitted by some of the LEDs 32 directly illuminates the translucent light ring 40, making it produce a uniform and bright light effect throughout. Because the translucent light ring 40 adopts frosted light guiding properties, its light presents a soft and continuous flowing feeling, thus forming a "ring of light" effect around a planet.

[0061] A dynamic starry sky projection is formed by an upward light path, while another portion of the light shines upward, passing through the starry sky pattern on the projection paper 50 to form a light projection with patterned texture. After being diffracted by the pattern, the light finally shines on the inner wall of the hemispherical projection dome 60, making the hemispherical surface present a clear and layered starry sky pattern. As the color and brightness of the LED light 32 gradually change over time, the color of the projected pattern also changes accordingly, thus creating a slowly flowing and continuously changing dynamic starry sky visual effect.

[0062] Through the above dual-light path setup, this embodiment achieves a planet effect composed of a ring light band and a dynamic starry sky pattern, presenting a rich and dynamically changing visual presentation.

[0063] like Figure 5 As shown in Figure 9, the assembly steps of the dynamic projection decoration part 105 in this embodiment are as follows: First, the light source 30 is fixedly installed on the inner mounting position of the lower cover 10; then, the light-transmitting ring 40 is placed in the annular groove formed at the joint position of the lower cover 10 and the annular upper cover 20; and the projection paper 50 is laid on the platform of the light-transmitting ring; next, the annular upper cover 20 is fastened and fixed on the lower cover 10, so that the whole constitutes a sealed planet-shaped shell; the hemispherical projection cover 60 is installed at the top opening of the annular upper cover 20; finally, the assembled dynamic projection decoration part 105 is fixedly installed on the upper end of the main body 103.

[0064] After the above assembly, the dynamic projection decoration part 105 forms an integral module, which has the characteristics of compact structure, convenient installation and stable light effect.

[0065] Preferably, the light-transmitting ring 40 is made of frosted semi-transparent light-guiding material, and its shape matches the ring groove of the planet-shaped shell, and is clamped between the lower cover 10 and the ring-shaped upper cover 20.

[0066] When the LED light 32 emits light horizontally, the light undergoes multiple refractions and diffusions inside the light-transmitting ring 40, causing the light-transmitting ring 40 to present a continuous and uniform light emission state, forming a visual effect similar to a planetary "ring".

[0067] Furthermore, preferably in this embodiment, such as Figure 3As shown, a reflective layer is provided on the inner wall of the lower cover 10 and / or the annular upper cover 20. The reflective layer covers the main light-illuminating area inside the housing, and its material can be a metal coating film with high reflectivity or a white reflective coating. The reflective layer causes the light emitted by the light source 30 to undergo multiple reflections inside the housing, thereby reducing the scattering loss of light energy in non-light path directions and improving the utilization efficiency of effective light.

[0068] Specifically, when the LED light 32 emits light upwards or horizontally, some of the light is reflected by the reflective layer on the inner wall of the housing and redirected into the effective light path of the light-transmitting ring 40 or the projection paper 50. This makes the star ring light effect presented by the light-transmitting ring 40 more uniform and brighter, while also making the starry sky pattern formed by the projection paper 50 brighter and clearer. Through the setting of this reflective layer, the entire dynamic projection decoration section 105 can achieve better light effect performance without increasing the number of light sources, thereby improving the overall decorative effect.
