Flame simulation device

Abstract

The invention discloses a flame simulation device comprising a casing (1) and the following components arranged in the casing (1): an analog hearth (2), at least one light source (3) of an imaging screen (6) and a transparent cylinder (4), wherein the light sources (3) of the imaging screen (6) are arranged at the back side of the casing (1), the transparent cylinder (4) is positioned above the light sources (3), liquid which can fluctuate is arranged in the transparent cylinder (4), the light sources (3) are laser beams, and the imaging screen (6) is unidirectional mirror glass which is semi-transparent. Compared with the prior art, the invention forms a dynamic flame simulation image with diversified size transformation and uninterrupted up-and-down leap on the imaging screen finally by light rays penetrating through the transparent cylinder through utilizing the characteristics of strong directivity, very high brightness, high degree of coherence, large energy density and the like of the laser beams and simulates flame as real flame, the simulated flame has a graceful effect, can jump, leap and twinkle randomly and has different positions and very strong stereoscopic impression, the brightness is also very good, and the combustion state is very lifelike.

Description

technical field [0001] The invention relates to a flame simulating device for simulating an electric fireplace, in particular to a flame simulating device capable of simulating the realistic effect of flames moving around on simulated combustion objects during combustion. Background technique [0002] Most of the home decorations in European and American countries are equipped with fireplaces for heating. However, as the international community puts forward higher and higher requirements for energy and environmental protection, real fireplaces are gradually replaced by simulated electric fireplaces. Because the simulated electric fireplace adopts flame simulation technology, it does not need to ignite real fuel, which can reduce environmental pollution, maintain ecological balance, easy installation, and clean and hygienic use. At present, it is very popular in domestic European-style home decoration styles. [0003] The core technology of simulating electric fireplace and s...

Problems solved by technology

[0004] In the flame simulating device, the light source passes through the notch in the shape of the outer contour of the flame in the light shield, and the shape of the notch on the light shield is fixed, so that the type of the outer contour of the flame is single. The shape of the pile of flames on the screen can never change; moreover, since the imaging screens are all flat, the simulated combustion state of a pile of flames is displayed on the imaging screen, and the three-dimensional effect of the flame simulation image is poor, and the flame outline is always fixed, making the flames The shape is not realistic enough, and the simulation is not realistic enough. It cannot simulate the shape of flames that are big and small, up and down, bright and dark, especially the faint and moving flames that are produced by burning charcoal.

[0005] On the other hand, since the simulated flame images are all imaged on a flat imaging screen, the user needs to see the simulated image through the imaging screen, and the light passing through the imaging screen will cause a large loss of light intensity. In the case of light bulbs or ordinary LEDs, the brightness of the simulated flame image is very limited
