DETAILED DESCRIPTION

[0024] The present application will be further described below with reference to the accompanying drawings.

[0025] Referring to FIGS. 1-4, a 3D flame projection system is provided, including a light source 1 and a light-transmittable hood 2. The light source 1 is disposed inside the light-transmittable hood 2. The 3D flame projection system further includes a lens 3 which has different refractive indexes for refracting light generated by the light source 1 and splitting the light into a plurality of light beams at different angles and/or has different light transmittances for allowing light generated by the light source 1 to partially transmit through the lens 3. Preferably, the lens 3 has different refractive indexes. More preferably, the lens 3 is designed to have an uneven refraction interface and thus form a plurality of small refraction interfaces. Preferably, to produce a more realistic flame effect, the lens 3 may be an optical lens with a particular color (e.g., the color of the flame). Preferably, the light source 1 and the light-transmittable hood 2 are arranged fixedly. Preferably, the light source 1 is an LED lamp panel. Preferably, hollow holes that are flame-shaped, ripple-shaped or the like are formed on the light-transmittable hood 2; or preferably, the light-transmittable hood 2 is an outer hood with light-transmittable patterns that are flame-shaped, ripple-shaped or the like. More preferably, the light-transmittable hood 2 may be an outer optical transparent hood with a particular color. In this structural design, after passing through the lens having different refractive indexes, light is split into a plurality of light beams having different refraction angles, so that a single light ray from the light source is split into refracted light rays having different angles, the dimensionality of the light is increased, and a more realistic 3D flame effect can be produced when the refracted light rays irradiate on the fake charcoal or other positions; and/or, after passing through the lens having different light transmittances, a single light ray from the light source will be scattered to form light beams having different brightness, so that the effect of brightness and darkness of the simulated flame is produced and the 3D flame effect is more realistic. After the light passes through the light-transmittable hood, a flame shape, a ripple shape or the like is produced. Thus, when the light is projected to the fake charcoal or other places, it is more realistic and vivid.

[0026] As shown in FIGS. 1 and 4, the 3D flame projection system further includes a motor 4. The lens 3 is connected to a motor shaft of the motor 4, and the rotation of the motor shaft drives the lens 3 to rotate together. Accordingly, when the motor shaft is arranged fixedly, the lens 3 may also be disposed on a main body of the motor 4. In this structural design, the lens rotates along with the motor shaft, so the light is changed in terms of refraction angle and/or brightness, realizing the flickering of the light. Accordingly, the simulated flame exhibits flickering and the effect is more realistic.

[0027] As shown in FIGS. 1 and 4, the lens 3 is disposed between the light source 1 and the light-transmittable hood 2.Correspondingly, the lens 3 may also be disposed outside the light-transmittable 2, so the light transmits through the hollow holes or light-transmittable patterns on the light-transmittable hood 2 and then transmits through the lens 3. However, in order to reduce the space occupation of the 3D flame projection system, preferably, the lens 3 is disposed between the light source 1 and the light-transmittable hood 2. In this structural design, the lens is closer to the light source, the use of the small-size lens can easily realize the adjustment of light, and the production cost is reduced. Moreover, this structural design realizes a more compact structure of the projection system, reduces the space occupation of the projection system, and is more advantageous for the realization of ultrathin production of fireplaces.

[0028] As shown in FIG. 4, a fireplace is provided, which uses the 3D flame projection system described above. Preferably, the 3D flame projection system is disposed on the top of an inner chamber of a housing of the fireplace. Preferably, the 3D flame projection system may also be disposed on the side face and/or bottom of the inner chamber of the housing of the fireplace. Generally, in order to ensure that the fireplace realizes highly simulated 3D flame, the 3D flame projection system may be disposed on each of the top, side face and bottom of the inner chamber of the housing of the fireplace, and the ON or OFF and intensity of the light source of the 3D flame projection system and the power-on/off and operation speed of the motor are controlled by a control system, so that the brightness of the simulated flame in the fireplace is controlled and the simulation effect is better.

[0029] As shown in FIG. 4, the fireplace further includes at least one of fake charcoal 5, stones, crystal particles and glass particles. Preferably, the fireplace includes at least two of fake charcoal 5, stones, crystal particles and glass particles. Preferably, the light emitted by the 3D flame projection system irradiates on the fake charcoal 5 and the rear plate of the inner chamber of the housing of the fireplace, or even irradiates on the reflective material such as crystal particles or glass particles. With the rotation of the lens 3, the flickering of the flame is realized and the realistic 3D flame effect is produced. This is totally different from the effect of the planar projection.

[0030] As shown in FIG. 4, the fireplace further includes a tray 7 used for containing at least one of fake charcoal 5, stones, crystal particles and glass particles. After a user purchases a fireplace, at least one of the fake charcoal, stones, crystal particles and glass particles may be provided to the user as a gift. The user may choose to decorate the fireplace with which material according to his/her preference. Thus, the user's fun of DIY is enhanced, and the fireplace is more personalized.

[0031] As shown in FIG. 4, at least one of the fake charcoal 5, stones, crystal particles and glass particles is divided into a front pile 51 and a rear pile 51, between which a gap is provided.

[0032] As shown in FIG. 4, a reflector 6 used for reflecting light emitted by the 3D flame projection system is provided at the gap. Preferably, the reflector 6 is disposed in the tray 7. Preferably, the reflector 6 is a reflector plate. The reflector plate is arranged at a certain angle so that the light emitted by the 3D flame projection system is reflected onto the front pile 51, the rear pile 52 and/or the rear plate of the inner chamber of the housing of the fireplace. More preferably, the light is reflected onto the rear pile 52 and/or the rear plate of the inner chamber of the housing of the fireplace. Preferably, the reflector 6 may also be a rotating shaft that is driven to rotate by the motor and has reflective sheets provided thereon. More preferably, the reflective sheets are uniformly distributed in a circumferential direction of the rotating shaft. By this structural design, the light irradiating on the reflector can be further reflected onto the fake charcoal, the tray (ash collector), the rear plate of the inner chamber of the housing of the fireplace or other places, and the simulated flame has a more realistic effect.

[0033] As shown in FIG. 4, the fireplace further includes a control system 8 connected to the 3D flame projection system. Preferably, the control system 8 receives a user's instruction and controls the ON or OFF and intensity of the light source 1 in the 3D flame projection system, the power-on/off and operation speed of the motor 4 and the like. More preferably, the control system 8 presets a plurality of modes for the brightness of the light source and the operation speed of the motor, and the user may start different modes according to the environmental conditions and personal requirements. The fireplace in such a design can better reflect the personalized requirements of the user.

[0034] As shown in FIG. 4, the fireplace further includes a heating system 9. The heating system 9 includes a heating element 91 and a fan 92. Preferably, the heating system 9 is disposed on the top of the inner chamber of the housing of the fireplace. By this hidden structural design, the exposed heating system 9 cannot be seen by the user in appearance. Preferably, the heating system 9 is connected to the control system 8. The control system 8 receives a user's instruction and controls the heating of the heating element 91, and air heated by the heating element 91 is blown out from the fireplace and blown towards the user. More preferably, the control system 8 presets a plurality of modes for the heating strength of the heating element and the operation speed and blowing angle of the fan, and the user may start different modes according to the environmental conditions and personal requirements. Similarly, The fireplace in such a design can better reflect the personalized requirements of the user.

[0035] Further, the fireplace further includes a door or curtain used for isolating the user from the inner chamber of the housing of the fireplace. Thus, the fireplace is beautiful in appearance and can better match the style of home decoration. Preferably, the fireplace uses a glass door or a mesh curtain.
