Description

Technical Field

[0001] The invention relates to the technical field of home furnishing and decoration equipment, in particular to a simulated flame device. Background Art

[0002] The simulated flame device is a device that simulates the flame effect through technical means. It uses the principle of light reflection by reflectors to continuously change the position, angle, direction, etc. of reflectors to simulate the effect of the flickering and changing flame light. The simulated flame device is often used for interior decoration, such as hotels, restaurants, bars and other places, to create a warm, romantic or mysterious atmosphere. It is widely used in various occasions that need to create a flame atmosphere or conduct related demonstrations.

[0003] At present, the simulated flame device on the market generally uses a motor to drive the shaft (a plastic rod of a certain length) to rotate, and a high-brightness reflective sheet is inserted into the shaft. The reflective sheet is driven to rotate by the shaft, and the light and the imaging screen are used to form an image. The reflection of the reflective sheet is projected onto the imaging screen through the lighting effect, forming a dynamic simulated flame effect. The most commonly used shape of the shaft on the market is the straight line type. One motor drives one shaft. When a square simulated flame device is needed, four motors and four shafts are required to form a square. When a simulated flame device with complex shapes such as circles, polygons, and multi-fold lines is required, multiple motors can only be used to drive multiple shafts, and multiple shafts are pieced together to form a complex shape.

[0004] Especially for circular simulated flame devices, the only way to approximate the simulation is to increase the number of motors and shafts as much as possible and improve the number of polygonal variables.

[0005] This can cause the following problems: 1. The overall structure of the product is relatively large, with a diameter of more than 500mm.

[0006] 2. Since the rotating shaft can only use a straight line shape, when the shape is complex, one straight line edge requires a motor drive, and multiple motors need to be set up as a whole. The mechanical friction and vibration of multiple motors are superimposed, resulting in louder noise.

[0007] 3. When a polygon is used to approximate a circle, there is an uneven distance between the vertices of the polygon and the circular imaging screen, resulting in an unrealistic flame effect or shadows. Summary of the invention

[0008] In view of this, the purpose of the present invention is to provide a simulated flame device, which can limit the shape of the bellows through a bracket, and drive the bellows to rotate on the bracket through a motor to drive the reflector to reflect light, so as to achieve the effect of simulated flame light flickering and changing. In addition, the bracket and the bellows are highly plastic and can be set into a variety of shapes, especially the imaging distance of a circle of arc is equal, the flame effect is realistic and there is no shadow, a single motor can drive the bellows, the mechanical friction and vibration are smaller, the noise is lower, and the structure is compact.

[0014] Specifically, the bellows is an elastic member, which is sleeved on the bracket and produces elastic deformation. When the motor drives the bellows to rotate on the bracket, the shape of the bellows remains the same as that of the bracket.

[0015] Specifically, the simulated flame device also includes a wear-resistant part, which is a polytetrafluoroethylene sleeve, a PP sleeve, a PVC sleeve, or a heat shrink sleeve. The wear-resistant part is sleeved on the bracket and arranged between the corrugated tube and the bracket to fill the gap and reduce the friction between the corrugated tube and the bracket.

[0016] Specifically, the simulated flame device also includes a light baffle, which is fixedly connected to the shell, and the light baffle and the imaging plate are arranged on two sides of the bellows opposite to each other, and the light baffle is used to block light from interfering with the imaging plate.

[0017] Specifically, the shape of the bracket is an arc and limits the shape of the bellows to also be an arc. The motor, the bracket and the bellows form a ring. The imaging plate is arranged around the outer ring, and the light-blocking plate is arranged on the inner ring.

[0018] Specifically, the simulated flame device further comprises a light source, which is fixedly connected to the housing, and the light emitted by the light source irradiates the reflector, and the imaging plate is arranged in the path of the light reflected from the reflector.

[0019] In summary, the embodiment of the present invention can limit the shape of the bellows by the bracket, and drive the bellows to rotate on the bracket by the motor to drive the reflector to reflect light, so as to achieve the effect of simulating the flickering and changing light of the flame.

[0039] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0040] The following is a detailed description through specific embodiments: like Figures 1 to 5 As shown, the first embodiment of the present invention provides a simulated flame device, including a bellows 10, a reflector 20, a housing 60, and a bracket 30 and a motor 40 fixedly arranged on the housing 60, wherein the reflector 20 is fixedly arranged on the bellows 10, one end of the bellows 10 is fixedly connected to the motor 40, the bracket 30 extends into the bellows 10 from the other end of the bellows 10, and the motor 40 is used to drive the bellows 10 to rotate on the bracket 30; In this embodiment, the simulated flame device also includes an imaging plate 61, which is fixedly connected to the shell 60 and is arranged on one side of the bellows 10. When the bellows 10 rotates, the reflector 20 rotates accordingly and reflects light onto the imaging plate 61 to form a simulated flame effect.

[0041] In this embodiment, the bracket 30 includes a support portion 31 and a leg portion 32 fixedly connected to the shell 60, the support portion 31 extends into the internal space of the corrugated tube 10, and the shape of the support portion 31 is arc-shaped, or wavy, or spiral, or multi-fold line-shaped. The corrugated tube 10 is a hollow sleeve, and the internal space of the corrugated tube 10 refers to the internal cavity of the hollow sleeve. Specifically, in this embodiment, the support portion 31 is parallel to the shell 60, and there is an angle between the leg portion 32 and the shell 60 and the support portion 31. The leg portion 32 is used to support and fix the support portion 31, and to fix the support portion 31 to the shell 60.

[0042] In this embodiment, the bellows 10 is sleeved on the support portion 31, and there is a gap between the end of the support portion 31 extending into one end of the bellows 10 and the motor 40, and there is a gap between the portion of the bellows 10 sleeved on the support portion 31 and the leg portion 32. The gap between the end of the support portion 31 extending into the bellows 10 and the motor 40 is used to separate the support portion 31 from the motor 40 to prevent the motor 40 from hitting the support portion 31 when rotating. The gap between the portion of the bellows 10 sleeved on the support portion 31 and the leg portion 32 is used to prevent the leg portion 32 from affecting the rotation of the bellows 10 when the bellows 10 rotates on the support portion 31.

[0043] Specifically, the housing 60 is a disc-shaped bottom plate, the motor 40 is a stepping motor, the leg portion 32 of the bracket 30 and the motor 40 are both fixedly connected to the housing 60, the support portion 31 of the bracket 30 is suspended and faces the direction of the motor 40, one end of the bellows 10 is fixedly connected to the output shaft of the motor 40, and the other end is sleeved on the support portion 31, when the motor 40 drives the bellows 10 to rotate on the support portion 31, the shape of the bellows 10 is limited to always remain the same as the shape of the support portion 31. The simulated flame device of the present invention uses the motor 40 to drive the bellows 10 to rotate, and a plurality of reflectors 20 are installed on the bellows 10, and the reflectors 20 rotate together with the bellows 10, and the reflectors 20 are reflective sheets, and the parameters such as the angle, direction, and size of each reflector 20 are random, so as to produce the unpredictable effect of simulated flame light.

[0044] In this embodiment, the shape of the bellows 10 is limited by the shape of the bracket 30. When the bellows 10 rotates along its own axis, the overall shape of the bellows 10 remains in an arc shape, thereby limiting the reflector 20 from continuously moving on a circular arc. The bellows 10 is a hollow steel wire hose, and the support portion 31 of the bracket 30 is a solid iron wire in an arc shape. The cross-sectional shape of the iron wire is circular, and the shape of the bellows 10 is also limited to an arc shape (approximately circular) by the arc shape of the iron wire. The iron wire needs to be made of high-strength mold steel, and the diameter of the iron wire must not be less than 3.5 mm, otherwise the iron wire is not strong enough and is prone to bending and deformation, which is not enough to fully support the bellows 10 to rotate on it.

[0045] The prior art usually uses multiple plastic rods or stainless steel rods to form a polygon. The more sides the polygon has, the closer the overall shape is to a circular structure. However, since one side corresponds to one plastic rod or stainless steel rod and one side corresponds to being driven by one motor 40, the more sides there are, the more motors 40 there are, the larger the overall size, the greater the noise, and it is difficult to achieve a perfect circular flame display effect.

[0046] The present invention uses a motor 40 to directly drive a bellows 10, and one end of the bellows 10 is fixedly connected to the output shaft of the motor 40 and rotates with the output shaft. Compared with a polygonal structure in which multiple motors 40 drive multiple plastic rods or stainless steel rods, the noise problem caused by multiple motors 40 is solved, and the mechanical friction sound of the present invention is smaller than the friction sound generated by the rotation of multiple transmission mechanisms on the market. And because fewer parts are used, the size of the product can be very small. The size of the product on the market is more than 500mm in diameter, and the present invention can be driven by a single motor 40, and the product size can be 160mm or less in diameter.

[0047] In this embodiment, the bellows 10 is a hollow hose, and the inner wall surface of the bellows 10 is in contact with the outer wall surface of the bracket 30 . When the bellows 10 rotates, the shape remains the same as that of the bracket 30 .

[0048] Specifically, the bellows 10 is a stainless steel threading hose, which is integrally formed. The bellows 10 includes a stainless steel threading hose. The stainless steel threading hose is made of 304 stainless steel or 301 stainless steel, and is used as a wire and cable protection tube for wires, cables, and automation instrument signals, with specifications ranging from 3mm to 150mm. Ultra-small diameter stainless steel threading hose (inner diameter 3mm-25mm) is mainly used for sensor line protection of precision optical rulers and industrial sensor line protection, and has good softness, corrosion resistance, high temperature resistance, wear resistance, and tensile resistance. The bracket 30 is a solid iron wire. During the rotation of the bellows 10, the structure of the bracket 30 remains fixed, and the shape of the bellows 10 remains the same as the shape of the bracket 30.

[0049] In this embodiment, the simulated flame device also includes a wear-resistant part 50, which is a polytetrafluoroethylene sleeve, a PP sleeve, a PVC sleeve, or a heat shrink sleeve. The wear-resistant part 50 is sleeved on the bracket 30. The wear-resistant part 50 is arranged between the corrugated pipe 10 and the bracket 30 to fill the gap and reduce the friction between the corrugated pipe 10 and the bracket 30.

[0050] Specifically, the bellows 10 is a circular hollow hose with a cross-section in the shape of a ring. It can be rotated in any direction and bent into any shape without affecting its rotation. The wear-resistant part 50 is a polytetrafluoroethylene sleeve, or a PP sleeve, or a PVC sleeve, or a heat shrink sleeve, which is sleeved on the outer surface of the support part 31 as a filler. The outer surface of the wear-resistant part 50 contacts the inner surface of the bellows 10 to reduce the gap between the support part 31 and the bellows 10, avoiding problems such as shaking, shaking, and friction caused by the gap during rotation, and also avoiding noise. The function of the wear-resistant part 50 is to reduce the friction sound of rotation. The problem to be solved is the noise problem, which includes the noise of the motor itself and the rotation noise. Optionally, lubricating products such as grease can be applied between the wear-resistant part 50, the bellows 10, and the bracket 30 to further reduce friction and noise. The wear-resistant part 50 is sleeved on the bracket 30 and fixedly connected to the bracket 30. When the bellows 10 rotates, the wear-resistant part 50 and the bracket 30 remain stationary. The wear-resistant part 50 has good wear resistance, which prevents the bellows 10 from directly contacting the bracket 30 and causing wear.

[0051] like Figures 2 to 4 As shown, in this embodiment, the wear-resistant part 50 is sleeved on the support part 31 of the bracket 30, and the bellows 10 is sleeved on the wear-resistant part 50; the wear-resistant part 50 is fixedly connected to the support part 31 of the bracket 30, the inner wall surface of the bellows 10 contacts the outer wall surface of the wear-resistant part 50, and the wear-resistant part 50 is used to reduce the friction force from the wear-resistant part 50 when the bellows 10 rotates; the shape of the wear-resistant part 50 is the same as the shape of the support part 31 of the bracket 30, and the bellows 10 is continuously bent and deformed during the rotation process to maintain its The shape is the same as that of the support portion 31 of the bracket 30; the bellows 10 is a hollow sleeve, one end of the support portion 31 extends into the bellows 10 along its axial direction, and the other end of the support portion 31 is fixedly connected to the leg portion 32 and fixed together on the housing 60; one end of the bellows 10 is fixedly connected to the output shaft of the motor 40, and the other end is inserted into the support portion 31, and there is a distance between the end of the support portion 31 and the end of the output shaft of the motor 40; similarly, there is also a distance between the end of the bellows 10 and the leg portion 32. The motor 40, the bracket 30, and the wear-resistant part 50 are all relatively fixed, and only the output shaft of the motor 40 rotates, driving the bellows 10 and the reflector 20 to rotate together.

[0052] In another implementation of this embodiment, the bellows 10 is not only a hollow hose (ie, the bellows 10 only includes a tube body), Figure 5 As shown, the bellows 10 may also include a tube body 11 and an elastic member 12, one end of the tube body 11 is fixedly connected to the motor 40, the other end of the tube body 11 is sleeved on the bracket 30, and the elastic member 12 is installed on the outside, inside or inside the tube wall of the tube body 11 to provide resilience when the tube body 11 rotates. The material of the tube body 11 can be a soft and elastically deformable material, such as rubber.

[0053] Specifically, the elastic member 12 may be a spring. The tube body 11 utilizes the bendability of the elastic member 12, and the elastic member 12 is wound on the outer wall surface or the inner wall surface of the tube body 11. Optionally, the elastic member 12 may also be embedded in the wall of the tube body 11. The elastic member 12 makes the tube body 11 have a high axial elasticity. When the bellows 10 is not mounted on the bracket 30, the bellows 10 is in a state of being retracted under the resetting action of the elastic member 12. Figure 5 (a) is in the straightened state. When the bellows 10 is mounted on the bracket 30, the bellows 10 is in the straightened state. Figure 5 In the bending state shown in (b), the motor 40 drives the bellows 10 to rotate along the axial direction. When the entire bellows 10 is bent in an arc shape under the pressure of the bracket 30, the elastic member 12 itself can be adaptively deformed, the inner ring diameter is reduced, and the outer ring diameter is increased. At this time, the bellows 10 can still rotate normally. The basic principle utilizes the variability of the elastic member 12. When in a bending state, the pitch of the inner side of the arc of the elastic member 12 is further compressed, and the pitch of the outer side of the arc of the elastic member 12 is further increased. During the rotation process, the elastic member 12 turns from the inner ring diameter to the outer ring diameter, and the pitch of the elastic member 12 changes from small to large. The outer diameter turns to the inner diameter, and the elastic member 12 turns from the outer ring diameter to the inner ring diameter, and the pitch of the elastic member 12 changes from large to small. In other words, no matter how the shape of the bellows 10 changes, the elastic member 12 can automatically adjust the pitch as the bellows 10 rotates. The bellows 10 can solve the rotation problem in different shapes, not only limited to arc shapes, but also applicable to brackets 30 with complex shapes such as circular, polygonal, and multi-fold lines.

[0054] Specifically, a single motor 40 is used to directly drive the bellows 10 to rotate. The shape of the bellows 10 is bent into an arc segment that is approximately a circle along with the bracket 30 . The distance between the bellows 10 and the imaging plate 61 (imaging screen) is uniform.

[0055] In this embodiment, the simulated flame device also includes a light baffle 62, which is fixedly connected to the shell 60. The light baffle 62 and the imaging plate 61 are relatively arranged on both sides of the bellows 10. The light baffle 62 is used to block light from interfering with the imaging plate 61.

[0056] In this embodiment, the shape of the bracket 30 is an arc and the shape of the limiting bellows 10 is also an arc. The motor 40, the bracket 30 and the bellows 10 form a circular ring, the imaging plate 61 is arranged around the outer ring, and the light blocking plate 62 is arranged on the inner ring.

[0057] In this embodiment, the simulated flame device also includes a support member 63, the bottom of which is fixedly disposed on the housing 60. The support member 63 is used to support the bellows 10, to assist in limiting the shape of the bellows 10, and to prevent the bellows 10 from deforming during rotation.

[0058] Specifically, the structure of the simulated flame device is compact, the motor 40, the bracket 30, the wear-resistant part 50 and the bellows 10 form a circle, a light shielding plate 62 is provided inside the circle, and a surrounding imaging plate 61 is provided outside the circle. The overall size of the product is made to be 160 mm or less in diameter, which greatly reduces the space occupied by the product compared with the prior art.

[0059] On the other hand, since this embodiment uses only one motor 40 and one bellows 10, fewer parts are used as a whole, so the noise generated is also smaller.

[0060] In this embodiment, the simulated flame device further includes a light source 64 , which is fixedly connected to the housing 60 , and the light emitted by the light source 64 irradiates the reflector 20 , and the imaging plate 61 is arranged in the path of the light reflected from the reflector 20 .

[0061] Specifically, the reflector 20 is fixed on the bellows 10, and the reflector 20 rotates in a circular motion synchronously with the bellows 10 to form a ring-shaped rotation effect. The reflector 20 can be evenly arranged on the bellows 10. A circle of light sources 64 is arranged around the reflector 20. The light sources 64 are multiple groups of golden lamp beads, and the color of the light emitted by them is similar to the color of the flame. The model of the lamp beads is 3030 lamp beads, the power is 0.5W, and the light source 64 is fixedly arranged on the shell 60. A circle of imaging plates 61 is fixedly arranged on the outermost circle of the shell 60, and the color of the imaging plate 61 can be selected as brown semi-transparent. In this embodiment, the lamp bead model is preferably 3030 lamp beads, but it is not necessarily limited to this model. The 5050 model, 0.5W power or other models and power combinations can also be used. Different models or different powers of lamp beads present different light effects, and the color, power and brightness of the lamp will obviously affect the flame effect.

[0062] When the simulated flame device is used, the light emitted by the light source 64 irradiates the reflector 20, and the reflector 20 reflects the light through the mirror surface, and projects the light onto the imaging board 61 for imaging. The imaging board 61 shows the shape of the reflector 20, and the shape of the reflector 20 is made into a flame shape. The reflector 20 can be selected as a pet hot-dip aluminum film with a thickness within 0.1mm, which can reflect the light of the lamp beads. Then, after the light is reflected, the flame effect is projected onto the imaging board 61. The motor 40 drives the bellows 10 to rotate, and the bellows 10 continuously drives the reflector 20 to rotate, forming a dynamic flame simulation effect.

[0063] The advantage of the present invention is that a flexible bellows 10 is used for rotation. Compared with the plastic rods or iron rods commonly used on the market, the flexible bellows 10 can be bent into any shape. During the rotation process, the support portion 31 of the bracket 30 is used to shape the bellows 10. The bellows 10 always maintains the shape limited by the bracket 30, and the leg portion 32 of the bracket 30 is fixedly connected to the shell 60. Through such a setting, the bracket 30 can be prevented from shaking or moving, avoiding affecting the shaking or movement of the bellows 10, thereby avoiding the problem of poor imaging effect. During the whole process, in order to avoid or minimize the influence of light from the opposite side, a light blocking plate 62 is added to block light. The structure of the light blocking plate 62 is a circular structure, and its shape is similar to a circular sleeve. It is vertically fixed on the shell 60, and the light blocking plate 62 is set on the inner circle of the bellows 10. The light blocking plate 62 can be selected as a black opaque sheet metal, which is welded on the shell 60 to prevent problems such as ghosting confusion after multiple reflections of light.

[0064] It should be noted that when a larger annular simulated flame is required, the length of the bellows 10 can be lengthened and the diameter of the support portion 31 can be increased to meet the requirement of a larger size. The diameter of the simulated flame device can be increased or decreased by changing the diameter of the support portion 31 and the length of the bellows 10 for adaptive adjustment. Not only can it be increased, it can also be decreased. The structure of this embodiment has been proven to be able to reduce the diameter of the simulated flame device to 160 mm or less. The present invention is mainly intended to solve the transmission problem and utilize the characteristics of the bellows 10. It should be pointed out that the effects of the following other embodiments all fall within the scope of protection of the present invention.

[0065] The invention can be combined with a heating device to produce a circular simulated flame stove.

[0066] like Figure 6 As shown, the second embodiment of the present invention provides a simulated flame device, and its general structure is the same as that of the first embodiment. The difference is that in this embodiment, the bellows 10 is an elastic member, specifically a spring, and the bellows 10 is sleeved on the bracket 30 and produces elastic deformation. When the motor 40 drives the bellows 10 to rotate on the bracket 30, the shape of the bellows 10 remains the same as that of the bracket 30.

[0067] The bellows 10 is adopted as Figure 6 Compared with the first embodiment, the spring structure shown in the present embodiment has a simpler and more direct connection of the spring. Regardless of the form of the spring, such as a mold spring, a composite spring, an alloy spring, or a plastic-coated spring, its function and purpose are to solve the problem of circular rotation. Structural changes and adjustments to the spring structure are within the scope of protection of the present invention, and the purpose is to solve the rotation problem. Such flexible rotation is inseparable from the scope of protection of the present invention.

[0068] The third embodiment of the present invention provides a simulated flame device, the general structure of which is the same as that of the first embodiment. Figure 7 As shown, the difference is that the bellows 10 in this embodiment is a spring, and the two ends of the bellows 10 also include connectors 13, which are used to connect the output shaft of the motor 40, so that the bellows 10 rotates with the output shaft of the motor 40. Connectors 13 are provided on both sides of the bellows 10, and the connector 13 is a sleeve, and an opening is provided in the middle of the sleeve. The support part 31 of the bracket 30 extends into the bellows 10 through the opening, and the structure of the bellows 10 is shaped by the support part 31. By forming a circular rotating component combination in this way, this method can achieve circular rotation and also achieve a rotation effect. The reflector 20 is fixed on the sleeve, and the side of the sleeve is provided with an open groove along the circumference, which can be used to fix the reflector 20. It is a deformation result of the bellows 10, a multi-stage deformation, and also belongs to the protection scope of the present invention.

[0069] like Figure 8 As shown, the fourth embodiment of the present invention provides a simulated flame device, and its general structure is the same as that of the first embodiment. The difference is that the support portion 31 of the bracket 30 (not shown in the figure) is a multi-fold line shape formed by bending a straight line multiple times. The support portion 31 includes five straight line portions, and the angles between adjacent straight lines are the same and bent to form a regular polygon shape that is approximately a circular arc. The bellows 10 includes a plurality of hoses and a plurality of hard pipes connected in series, wherein the hoses and the hard pipes are fixedly connected to each other in sequence. The hard pipe is a straight pipe, which is responsible for forming the straight line portion of the multi-fold line, and the hose is a curved pipe, which is responsible for bending and twisting when the bellows 10 rotates as a whole, so that the bellows 10 as a whole maintains the shape of a multi-fold line.

[0070] like Figure 8 As shown, the output shaft of the motor 40 is a straight line, the first section of the bellows 10 is sleeved on the output shaft of the motor 40, the first section of the bellows is connected to the second section of the hard pipe after being bent, the other end of the hard pipe is connected to the third section of the bellows, and the third section of the bellows is connected to the next section of the hard pipe after being bent. Each of the bellows is bent in one direction at the same angle, and multiple bellows and multiple hard pipes form a bellows 10 in a multi-fold line shape.

[0071] The bottom of the support member 63 is fixedly arranged on the housing 60, and the hard tube is mounted on the support member 63 and can rotate on the support member 63. The support member 63 is used to limit the position of the hard tube when the corrugated tube 10 rotates, so that the overall shape of the corrugated tube 10 remains unchanged. The hard tube can be mounted on the support member 63 by opening a through hole on the support member 63, and the hard tube passes through the through hole, and the diameter of the through hole is set to be slightly larger than the diameter of the hard tube; or the support member 63 can clamp the hard tube, and the diameter of the clamp is set to be slightly larger than the diameter of the hard tube.

[0072] The reflective element 20 (not shown in the figure) is arranged on the corrugated tube 10, and can be arranged on a hard tube or a soft tube. When the corrugated tube 10 rotates, the reflective element 20 rotates accordingly.

[0073] In this embodiment, a polygonal bellows 10 is used to simulate a nearly circular simulated flame effect, and the bellows 10 rotates on the support member 63 under the drive of the motor 40 .

[0074] Multiple hoses and multiple hard pipes are connected in series, and then driven to rotate by a single motor 40. The purpose of this is to use the hose as a corner connection while reducing the size of the product. The power of this embodiment is output by the motor 40, and the hose of the bellows 10 is used as a transmission node. The fundamental purpose is to solve the transmission problem. The transit connection method of the curved hose of the bellows 10 can well reduce the size of the product. The smaller bellows 10 replaces the connection structure of multiple motors 40 in the prior art to drive multiple sides separately.

[0075] Large-sized products on the market usually use multiple motors 40 and multiple linear rods arranged in a polygonal structure, but since each side requires a motor 40 to drive, the size of the product cannot be reduced. The embodiment of the present invention uses a bellows 10 for transmission in the curved section, and a motor 40 can drive the bellows 10, solving the problems of the above-mentioned prior art. The embodiment of the present invention changes the rigid shaft rotation polygon into a transmission form of a flexible connection in the shape of an arc segment, that is, the bellows 10 can be deformed and rotated in any shape and angle.

[0076] In summary, the embodiment of the present invention can limit the shape of the bellows 10 by the bracket 30, and drive the bellows 10 to rotate on the bracket 30 by the motor 40 to drive the reflector 20 to reflect light, so as to achieve the effect of simulating the flickering and changing light of the flame. Moreover, the bracket 30 and the bellows 10 are highly plastic and can be set into a variety of shapes, especially the imaging distance of a circle of arc is equal, the flame effect is realistic and there is no shadow, a single motor 40 can drive the bellows 10, the mechanical friction and vibration are smaller, the noise is lower, and the structure is compact.

[0077] Moreover, the shape of the bracket 30 is arc, wave, spiral, or multi-fold line, which is suitable for designing simulated flame devices of different shapes.

[0078] The bellows 10 includes a tube body 11 and an elastic member 12 . The elastic member 12 is used to assist the tube body 11 to undergo elastic deformation when rotating, and to always keep in contact with the bracket 30 , thereby keeping the shape of the bellows 10 unchanged.

[0079] The simulated flame device also includes a wear-resistant part 50, which is a polytetrafluoroethylene sleeve. The wear-resistant part 50 is sleeved on the bracket 30 and is arranged between the bellows 10 and the bracket 30 to fill the gap and reduce the friction between the bellows 10 and the bracket 30.

[0080] The simulated flame device further includes an imaging plate 61, a light shielding plate 62, a light source 64, etc. The shape of the bracket 30 is an arc shape and the shape of the bellows 10 is also an arc shape. The motor 40, the bracket 30 and the bellows 10 form a ring, the imaging plate 61 is arranged around the outer ring of the ring, and the light shielding plate 62 is arranged in the inner ring of the ring. The light emitted by the light source 64 irradiates the reflector 20, and the imaging plate 61 is arranged in the light path reflected from the reflector 20.

[0081] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
