Description

Technical Field

[0001] The present invention relates to the technical field of simulated electric fireplaces, and in particular to a Mars simulation device and an electric fireplace capable of simulating the jumping of Mars. Background Art

[0002] As a decorative device integrating modern optical principles, the simulated electric fireplace has a more prominent decorative effect and is the most widely spread. It uses electric energy as the energy source, relies on the reflection of light to generate two-dimensional or three-dimensional flames, and is equipped with simulated charcoal. There is no open fire, and at the same time, it produces a visual effect of simulated flame combustion, with a realistic effect. Compared with traditional fireplaces, electric fireplaces do not produce soot, odor, or noise during combustion, not only can save costs, but also can bring an elegant and comfortable viewing effect, and enjoy the warmth and comfort brought by the electric fireplace.

[0003] In the prior art, in order to make the simulated fuel effect realistic, the usual method is to set a light source at the bottom or side wall of the simulated fuel to irradiate the simulated fuel, so as to produce a visual effect of combustion. However, this method cannot reflect the real effect during actual combustion. For example, it cannot reflect the sparks splashing out when charcoal burns, and the picture is relatively rigid, resulting in insufficient realism and three-dimensional sense. Summary of the Invention

[0004] The first object of the present invention is to overcome the deficiencies of the prior art and provide a Mars simulation device that can simulate the floating effect of Mars.

[0005] The second object of the present invention is to provide a simulated electric fireplace equipped with the above-mentioned Mars simulation device.

[0006] The present invention is realized by the following technical solutions: A Mars simulation device includes a light source, a reflector, a rotating reflector assembly, and an imaging plate; after the light source is powered on, it emits a first parallel light beam; the reflector is fixedly arranged in the path of the first parallel light beam, and a plurality of first reflecting sheets are provided on the reflector, and these first reflecting sheets reflect the first parallel light beam into a plurality of second parallel light beams with different reflection angles; the rotating reflector assembly includes a rotating shaft and a plurality of second reflecting sheets arranged on the rotating shaft, and the plurality of second reflecting sheets sequentially and cyclically interfere into the path of the second parallel light beam as the rotating shaft rotates and reflect a plurality of third parallel light beams; the imaging plate is fixedly arranged in the paths of the plurality of third parallel light beams.

[0007] Compared with the prior art, the present invention uses a light source to emit a light beam that irradiates a reflector provided with a number of reflecting sheets to form a plurality of small bright spots. The reflector reflects the small light spots to the rotating reflector assembly, and then the rotating reflector assembly reflects them to an imaging plate in the shape of a spark. At the same time, the rotating reflector assembly rotates continuously. As the rotation angle changes, the shape and position of the bright spots irradiated on the imaging plate will change, so that bright spots that suddenly appear and disappear are formed on the imaging plate, achieving the effect of simulating the upward and downward moving spark jumps generated by the burning of charcoal, and improving the realism and three-dimensional sense of the simulated fuel combustion.

[0008] Further, the surface of the reflector irradiated by the first parallel light beam is a curved surface, and the number of first reflecting sheets is arranged on the curved surface.

[0009] Further, the reflector is a rotating body, and the generatrix of the rotating body is a single-peak curve segment; the rotation axis of the rotating body is perpendicular to the first parallel light beam.

[0010] Further, the number of first reflecting sheets is arranged in a circle along the circumferential direction of the rotating body and are closely arranged in several circles along the axis of the rotating body. When the light beam irradiates the reflector, since the surface of the reflector is a curved surface and the angles of each reflecting sheet provided on the surface of the reflector are different, several small light spots with different reflection angles can be generated. At the same time, reflected light rays that spread outward in the horizontal direction are generated, increasing the reflection range in the horizontal direction; at the same time, changing reflection angles are also generated in the vertical direction.

[0011] Further, the light source is at least one laser diode. The light emitted by the laser diode is concentrated, and the generated small light spots are brighter.

[0012] Further, the rotating reflector assembly further includes a motor and two clamping seats; the motor is fixedly arranged; one end of the rotating shaft is coaxially connected to the output shaft of the motor; the two clamping seats are alternately penetrated and fixed on the shaft body of the rotating shaft; the number of second reflecting sheets are alternately arranged along the circumferential direction of the rotating shaft, and both ends of each second reflecting sheet are respectively clamped in the two clamping seats. The small light spots formed by the reflector are reflected to the imaging plate through the regularly arranged second reflecting sheets for imaging again, and the shape of the small light spots can still be maintained.

[0013] Further, each second reflecting sheet is in the shape of a rectangular flat plate, and a number of square-tooth-shaped reflecting portions are formed thereon.

[0014] Further, the square-tooth-shaped reflecting portions on two adjacent second reflecting sheets arranged alternately along the axis are staggered from each other.

[0015] Further, it further includes a simulated fuel and a simulated fuel light source, and the simulated fuel is arranged in front of the imaging plate.

[0016] To achieve the second object, the present invention is realized through the following technical solutions:

[0017] An imitation electric fireplace, comprising a housing, a window communicating with the inner cavity of the housing is provided on the front side of the housing, and the above-mentioned Mars simulation device is provided in the inner cavity of the housing.

In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0026] Please refer to Figure 1, the simulated electric fireplace of this embodiment includes a housing 10, a simulated fuel 20 and a simulated spark device disposed inside the housing 10; a window (not shown in the figure) communicating with the inner cavity of the housing 10 is provided on the front side of the housing 10, and the simulated spark device is disposed inside the housing 10 cavity.

[0027] The simulated fuel 20 is disposed close to the window, and when looking into the inner cavity of the housing from the window, the simulated fuel 20 can be seen. A simulated fuel light source 21 for illuminating the simulated fuel is further disposed below the simulated fuel 20; preferably, the simulated fuel light source 21 is an LED light source, the LED light source is orange-red or orange-yellow, and the simulated fuel 21 is preferably simulated charcoal.

[0028] The simulated spark device is disposed behind the simulated fuel 21, and the simulated spark device includes a light source 31, a reflector 32, a rotating reflector assembly 33 and an imaging plate 34 disposed on the same optical path; a plurality of first reflecting pieces 32a are provided on the reflector 32, and the light emitted by the light source 31 forms a plurality of small light spots when irradiated on the first reflecting pieces 32a, and the small light spots are reflected to the rotating reflector assembly 33 and then reflected to the imaging plate 34 for imaging.

[0029] The light source 31 can generate concentrated light. Preferably, the light source 31 is a red or orange-red laser diode. In this embodiment, the light source 31 is a single laser diode. The light source 31 of the present invention can also be set as a plurality of laser diodes and disposed towards the reflector 32 at multiple angles, so that the light emitted by the plurality of light sources 31 can irradiate on the reflector 32.

[0030] The surface of the reflector 32 is a curved surface, and the plurality of first reflecting pieces 32a are disposed on the curved surface 32; specifically, the reflector 32 is a rotating body, and the generatrix of the rotating body is a single-peak curve segment; the rotation axis of the rotating body is perpendicular to the light beam emitted by the light source 31. The plurality of first reflecting pieces are arranged in a circle along the circumferential direction of the rotating body and are closely arranged in a plurality of circles along the axis of the rotating body. Please refer to Figure 2 and Figure 3, in this embodiment, the middle of the reflector 32 is large and both ends are small. Preferably, the cross-section of the reflector 32 is circular, and its cross-sectional diameter gradually decreases from the middle to both ends along the central axis direction. Further, the reflector 32 is hollow or solid, and the reflector 32 is fixedly arranged in the optical path so that the light emitted by the light source irradiates on the reflector 32. Further, a plurality of first reflector sheets 32a are provided on the surface of the reflector 32. The first reflector sheets 32a are made of a reflective material, and the first reflector sheets 32a can be regular or irregular. Preferably, the first reflector sheets 32a are regular long strips, arranged in a circle along the circumferential direction of the curved surface body, and closely arranged in a plurality of circles along the axial direction of the curved surface body, that is, the surface of the curved surface body is regularly and closely arranged with a plurality of first reflector sheets. Specifically, the first reflector sheets 32a are strip-shaped metal sheets, and each first reflector sheet 32a is soft and can be attached to the outer surface of the reflector 32a by pasting. The light source 31 generates a first parallel light beam. Since the light beam has a certain size range (i.e., coverage area), when the size of the first reflector sheet is smaller than the diameter of the light beam, the first parallel light beam can cover and irradiate a plurality of first reflector sheets, and each irradiated first reflector sheet forms a plurality of second light beams with different reflection angles and reflects them onto the rotating reflector assembly.

[0031] Further, please refer to Figure 2, the rotating reflection component 33 includes a rotating shaft 331, a motor 332, two card seats 333, and a plurality of second reflecting sheets 334. The motor 332 is fixed on the side wall of the housing 10, and the rotating shaft 331 is connected to the rotating shaft of the motor 332 and extends along the axial direction of the rotating shaft of the motor 332; the two card seats 333 are disc-shaped, with through holes in the middle and a plurality of equally spaced through holes opened at the edges along the circumferential direction; both ends of the rotating shaft 331 respectively pass through the two through holes in the middle and are fixed between the two card seats 333, so that the two card seats 333 can rotate with the rotating shaft 331. Each second reflecting sheet 334 is in the shape of a rectangular flat plate, and a plurality of square-tooth-shaped reflecting parts 334a are formed thereon. The first end of each second reflecting sheet 334 has a certain width along the length direction, and a plurality of tooth-shaped reflecting parts 334a are distributed along the length direction. Each tooth-shaped reflecting part 334a is a regular long strip and is arranged at equal intervals. The shapes and sizes of both ends of each second reflecting sheet 334 match the through holes opened at the edges of the circumference of the card seat 333, so that both ends of each second reflecting sheet 334 can be respectively clamped in the corresponding two through holes of the two card seats 333, thereby being fixed between the two card seats 333 and being parallel to the rotating shaft 331. The plurality of second reflecting sheets 334 are arranged at intervals along the circumferential direction of the rotating shaft 331, and both ends of each second reflecting sheet 334 are respectively clamped in the two card seats 333. When installed, one end of two adjacent second reflecting sheets 334 are respectively inserted into the two card seats 333, so that the square-tooth-shaped reflecting parts 334a on the two adjacent second reflecting sheets 334 are staggered from each other. Specifically, the plurality of second reflecting sheets can be made of plastic, metal, or other reflective materials with a reflective effect. In this embodiment, the second reflecting sheets are integrally formed. Further, the tooth-shaped reflecting parts are arranged in an interleaved manner, that is, on two adjacent second reflecting sheets, each tooth on the tooth-shaped reflecting part of one second reflecting sheet is opposite to the gap between two adjacent teeth of the tooth-shaped reflecting part of the other second reflecting sheet. When the light source vertically irradiates each tooth-shaped reflecting part and is reflected, it can pass through the gap between two adjacent teeth on the adjacent second reflecting sheet and will not be interfered by the adjacent second reflecting sheet.

[0032] Further, the imaging plate 34 is the rear shell plate of the housing 10, and the rear shell plate is located behind the rotating reflection component 33. Preferably, a wallpaper with brick patterns is pasted on the rear shell plate.

[0033] The working principle of the present invention will be specifically described below. Please refer to Figure 3, a number of first reflective sheets are closely and regularly arranged on the surface of the reflective member. When the light source emits a light beam and irradiates on the surface of the reflective member, since the light beam has a certain size, the light beam will irradiate on multiple first reflective sheets at the same time. Here, it is assumed that the light rays emitted by the light source irradiate on the first reflective sheets B1, B2, and B3 located in the middle of the curved body at the same time. The first reflective sheets B1, B2, and B3 are located on the same arc in the axial direction of the curved body. Horizontally, when the light ray emitted by the light source 31 irradiates on the first reflective sheet B1, the reflected light ray is b1; when the light ray emitted by the light source 31 irradiates on the position of B2, the reflected light ray is b2; when the light ray emitted by the light source 234 irradiates on the position of B3, the reflected light ray is b3; since the shape of the reflective member 31 is large in the middle and small at both ends, and the first reflective sheets B1, B2, and B3 are on a curved surface, that is, the angles between the 3 first reflective sheets and the axis are different. According to the principle of light reflection, the reflected light rays b1, b2, and b3 will show an effect of spreading to both sides, that is, the reflected light rays b1, b2, and b3 are diffused outward at a certain angle with each other. Similarly, reflected light rays that spread outward will also be generated in the vertical direction. Therefore, when the light source emits a first parallel light beam and irradiates on the first reflective sheets with different angles, according to the principle of light reflection, reflected light beams that spread outward will be generated in both the horizontal direction and the vertical direction, that is, second parallel light beams with different angles are generated, and each first reflective sheet corresponds to generating one or more second parallel light beams. Thus, multiple small light spots that spread outward and have irregular reflection angles are formed in the visual effect. The second parallel light beam generated by the reflective member is reflected onto the second reflective sheet that rotates with the motor. Since the toothed reflective parts on the second reflective sheet are regularly arranged, the second reflective sheet reflects the second parallel light beam again to form a third parallel light beam onto the imaging plate and retains the shape of its small light spots, presenting an effect that the small light spots float upward in the visual effect.

[0034] During use, in this Embodiment 1, the light source generates a light beam, and the light beam irradiates on the fixedly arranged reflective member. Since a number of first reflective sheets are provided within the irradiation range of the light beam, each first reflective sheet visually corresponds to generating a small light spot, and the small light spot is reflected onto the rotating reflective assembly. Since the second reflective sheets of the rotating reflective assembly are regularly arranged, when the second reflective sheets rotate with the rotating shaft and the motor, they drive the small light spots to project and form an image on the rear housing plate, that is, illuminate the rear housing plate to leave a spark-shaped light spot. By controlling the rotation speed of the motor, the drifting speed of the light star on the rear housing plate can be controlled to obtain the best visual effect, and an effect of the spark surging will be generated on the rear housing plate.

[0035] Example 2

[0036] Please refer to Figure 4, Embodiment 2 of the present invention is basically the same as Embodiment 1, with the only difference being that the position and structure of the imaging plate are different. In this Embodiment 2, the imaging plate is a light-transmitting plate 34a, and the light-transmitting plate 34a is arranged between the simulated fuel 20 and the rotating reflecting component 32. Preferably, the light-transmitting plate 34a is a semi-transparent plate, and the semi-transparent plate is formed by processing hard transparent plastic with excellent optical properties.

[0037] During use, in this Embodiment 2, the point light source is arranged between the rotating reflecting component and the light-transmitting plate, and the light beam irradiates on the fixedly arranged reflecting member. Since there are multiple first reflecting sheets within the irradiation range of the light beam, each first reflecting sheet visually corresponds to a small light spot. The small light spot is reflected onto the rotating reflecting component. Due to the regular arrangement of the second reflecting sheets of the rotating reflecting component, when the second reflecting sheets rotate with the rotating shaft and the motor, they drive the small light spot to be projected onto the middle light-transmitting plate, that is, a spark-shaped light spot is left on the semi-transparent plate. By controlling the rotation speed of the motor, the drifting speed of the light star on the light-transmitting plate can be controlled to obtain the best visual effect, and the effect of sparks surging will be produced on the semi-transparent plate.

[0038] The beneficial effects produced by the present invention are as follows: 1. The present invention uses a point light source to emit a concentrated light beam and irradiates it on a reflecting member provided with several first reflecting sheets to form multiple small bright spots. The reflecting member reflects the small light spots onto the rotating reflecting component and then reflects them onto the imaging plate or the light-transmitting plate to form a spark shape. At the same time, the rotating reflecting component rotates continuously. As the rotation angle changes, the bright spots irradiated on the imaging plate will change in shape and position, thereby forming bright spots that suddenly brighten and dim on the imaging plate, achieving the effect of simulating the jumping of sparks that move up and down. 2. Since the reflecting member is a cylinder with a large middle and small ends, the angles of each first reflecting sheet provided on the surface of the reflecting member are different, and reflected light rays that spread outward will be generated in the horizontal or vertical direction, increasing the reflection range in the horizontal or vertical direction. Therefore, the coverage area of the small light spots reflected onto the rotating reflecting component is large. 3. The second reflecting sheets in the rotating reflecting component are arranged regularly. The small light spots formed by the reflecting member are reflected onto the imaging plate through the regularly arranged second reflecting sheets for imaging, and the shape of the small light spots can still be maintained.

[0039] The present invention is not limited to the above embodiments. If various modifications or deformations of the present invention do not depart from the spirit and scope of the present invention, and if these modifications and deformations fall within the scope of the claims of the present invention and equivalent technical scope, then the present invention also intends to include these modifications and deformations.
