Description

Technical Field

[0001] This utility model relates to the field of home furnishing and decoration equipment technology, and in particular to a simulated flame device. Background Technology

[0002] A simulated flame device is a device that uses technology to simulate the effect of flames. It utilizes the principle of reflective elements to reflect light, and by continuously changing the position, angle, and direction of the reflectors, it simulates the flickering and changing effect of flame light. Simulated flame devices are commonly used in interior decoration, such as in hotels, restaurants, and bars, to create a warm, romantic, or mysterious atmosphere. They are widely used in various occasions that require creating a flame atmosphere or conducting related demonstrations.

[0003] Currently, most simulated flame devices on the market use a motor to drive a rotating shaft (a plastic rod of a certain length), with a high-brightness reflector inserted through the shaft. The shaft drives the reflector to rotate, and in conjunction with lighting and an imaging screen, the reflected light from the reflector is projected onto the screen, creating a dynamic simulated flame effect. The most common shape for the rotating shaft is linear, with one motor driving one shaft. For a square simulated flame device, four motors and four shafts are needed to form a square. For more complex shapes such as circular, polygonal, or multi-zigzag simulated flame devices, multiple motors driving multiple shafts must be used, with the shafts pieced together to form the complex shape.

[0004] In particular, for circular simulated flame devices, the only way to approximate the simulation is to increase the number of motors and rotating shafts as much as possible and increase the number of polygon variables.

[0005] This will cause the following problems:

[0006] 1. The overall structure of the product is relatively large, with a diameter of over 500mm.

[0007] 2. Since the shaft can only use a straight line shape, when the shape is complex, one motor is needed to drive each straight line edge. Multiple motors need to be set up in the whole. The mechanical friction and vibration of multiple motors are superimposed, resulting in loud noise.

[0008] 3. Using polygons to approximate a circle results in uneven distances between the vertices of the polygons and the circular imaging screen, leading to unrealistic flame effects or shadows. Utility Model Content

[0009] In view of this, the purpose of this utility model is to provide a simulated flame device, which can restrict the shape of the corrugated tube by a bracket, and drive the corrugated tube to rotate on the bracket by a motor to drive the reflector to reflect light, so as to achieve the effect of simulated flame light flashing and changing. Moreover, the bracket and the corrugated tube are highly malleable and can be set into various shapes. In particular, the imaging distance of the arc is equal, the flame effect is realistic and there are no shadows. The corrugated tube can be driven by a single motor, with less mechanical friction and vibration, lower noise, and a compact structure.

[0010] This utility model provides a simulated flame device, including a corrugated pipe, a reflector, a housing, a bracket and a motor fixedly mounted on the housing. The reflector is fixedly mounted on the corrugated pipe, one end of the corrugated pipe is fixedly connected to the motor, the bracket extends into the corrugated pipe from the other end, and the motor is used to drive the corrugated pipe to rotate on the bracket.

[0011] The simulated flame device also includes an imaging plate, which is fixedly connected to the housing. The imaging plate is disposed on one side of the bellows. When the bellows rotates, the reflector rotates accordingly and reflects light onto the imaging plate to form a flame.

[0012] Specifically, the bracket includes a support portion and a leg portion fixedly connected to the housing. The support portion extends into the internal space of the bellows, and the shape of the support portion is arc-shaped, wave-shaped, spiral-shaped, or multi-fold line-shaped.

[0013] Specifically, the corrugated pipe is sleeved on the support portion, and there is a gap between one end of the support portion extending into the corrugated pipe and the motor, and there is a gap between the portion of the corrugated pipe sleeved on the support portion and the support leg portion.

[0014] Specifically, the corrugated tube is a hollow flexible tube, the inner wall of the corrugated tube is attached to the outer wall of the bracket, and the shape of the corrugated tube remains the same as the shape of the bracket when it rotates.

[0015] Specifically, the corrugated pipe includes a pipe body and an elastic element. One end of the pipe body is fixedly connected to the motor, and the other end of the pipe body is sleeved on the bracket. The elastic element is installed on the outside, inside or inside the pipe body to provide a restoring force when the pipe body rotates.

[0016] Specifically, the corrugated pipe is an elastic element. The corrugated pipe is sleeved on the bracket and undergoes elastic deformation. When the motor drives the corrugated pipe to rotate on the bracket, the shape of the corrugated pipe remains the same as the shape of the bracket.

[0017] Specifically, the simulated flame device also includes a wear-resistant component, which is a polytetrafluoroethylene sleeve, a PP sleeve, a PVC sleeve, or a heat-shrinkable sleeve. The wear-resistant component is sleeved on the bracket and is disposed between the corrugated pipe and the bracket to fill the gap and reduce the friction between the corrugated pipe and the bracket.

[0018] Specifically, the simulated flame device also includes a light-blocking plate, which is fixedly connected to the housing. The light-blocking plate and the imaging plate are respectively disposed on both sides of the corrugated pipe, and the light-blocking plate is used to block light from interfering with the imaging plate.

[0019] Specifically, the bracket is arc-shaped and the bellows is also arc-shaped. The motor, the bracket, and the bellows form a ring. The imaging plate is arranged around the outer ring of the ring, and the light-blocking plate is arranged in the inner ring of the ring.

[0020] Specifically, the simulated flame device also includes a light source, which is fixedly connected to the housing. The light emitted by the light source illuminates the reflector, and the imaging plate is positioned in the path of the light reflected from the reflector.

[0021] In summary, this embodiment of the invention can constrain the shape of the corrugated tube using a bracket, and drive the corrugated tube to rotate on the bracket via a motor to drive the reflector to reflect light, achieving a simulated flickering and constantly changing flame effect. Furthermore, the bracket and corrugated tube are highly malleable and can be configured into various shapes, especially the arc shape which provides a uniform imaging distance, realistic flame effect without shadows, and the corrugated tube can be driven by a single motor, resulting in less mechanical friction and vibration, lower noise, and a compact structure.

[0022] Moreover, the bracket can be arc-shaped, wave-shaped, spiral-shaped, or multi-fold line-shaped, making it suitable for designing simulated flame devices of different shapes.

[0023] Furthermore, the corrugated pipe includes a pipe body and an elastic element. The elastic element is used to assist the pipe body in undergoing elastic deformation when rotating, so as to always keep it in contact with the support and maintain the shape of the corrugated pipe.

[0024] Furthermore, the simulated flame device also includes wear-resistant parts, which are polytetrafluoroethylene sleeves, PP sleeves, PVC sleeves, or heat-shrinkable sleeves. The wear-resistant parts are fitted onto the bracket and placed between the corrugated pipe and the bracket to fill the gap and reduce friction between the corrugated pipe and the bracket.

[0025] Furthermore, the simulated flame device also includes an imaging plate, a light-blocking plate, and a light source. The support frame is arc-shaped, and the corrugated pipe is also arc-shaped. The motor, support frame, and corrugated pipe form a ring, with the imaging plate surrounding the outer ring and the light-blocking plate positioned on the inner ring. The light emitted by the light source illuminates the reflector, and the imaging plate is positioned within the path of the light reflected from the reflector. Attached Figure Description

[0040] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

They are used only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0043] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar attributes, not to indicate or imply relative importance or a specific order.

[0044] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0045] The following detailed explanation uses specific examples:

[0046] like Figures 1 to 5As shown, the first embodiment of this utility model provides a simulated flame device, including a corrugated pipe 10, a reflector 20, a housing 60, a bracket 30 fixedly mounted on the housing 60, and a motor 40. The reflector 20 is fixedly mounted on the corrugated pipe 10, one end of the corrugated pipe 10 is fixedly connected to the motor 40, the bracket 30 extends into the corrugated pipe 10 from the other end of the corrugated pipe 10, and the motor 40 is used to drive the corrugated pipe 10 to rotate on the bracket 30.

[0047] In this embodiment, the simulated flame device also includes an imaging plate 61, which is fixedly connected to the housing 60. The imaging plate 61 is disposed 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.

[0048] In this embodiment, the bracket 30 includes a support portion 31 and a leg portion 32 fixedly connected to the housing 60. The support portion 31 extends into the internal space of the bellows 10. The shape of the support portion 31 is arc-shaped, wavy, spiral, or multi-zigzag. The bellows 10 is a hollow sleeve, and the internal space of the bellows 10 refers to the internal cavity of the hollow sleeve. Specifically, in this embodiment, the support portion 31 is parallel to the housing 60, and the leg portion 32 has an angle with the housing 60 and the support portion 31. The leg portion 32 is used to support and fix the support portion 31 and fix the support portion 31 to the housing 60.

[0049] In this embodiment, the bellows 10 is sleeved on the support portion 31. A gap exists between the end of the support portion 31 extending into the bellows 10 and the motor 40, and a gap exists between the portion of the bellows 10 sleeved on the support portion 31 and the support leg portion 32. The gap between the end of the support portion 31 extending into the bellows 10 and the motor 40 serves to separate the support portion 31 from the motor 40, preventing 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 support leg portion 32 serves to prevent the support leg portion 32 from affecting the rotation of the bellows 10 when it rotates on the support portion 31.

[0050] Specifically, the housing 60 is a disc-shaped base plate, the motor 40 is a stepper motor, the support legs 32 of the bracket 30 and the motor 40 are both fixedly connected to the housing 60, the support part 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 part 31. When the motor 40 drives the bellows 10 to rotate on the support part 31, the shape of the bellows 10 is restricted to always remain the same as the shape of the support part 31. The simulated flame device of this utility model uses the motor 40 to drive the bellows 10 to rotate. Multiple reflectors 20 are installed on the bellows 10. The reflectors 20 rotate together with the bellows 10. The reflectors 20 are reflective sheets, and the angle, direction, size and other parameters of each reflector 20 are random, producing a simulated flame light effect that is unpredictable.

[0051] In this embodiment, the shape of the corrugated pipe 10 is restricted by the shape of the bracket 30. While the corrugated pipe 10 rotates along its own axis, its overall shape remains arc-shaped, thus restricting the reflector 20 from continuously moving along the arc. The corrugated pipe 10 is a hollow steel wire hose, and the support part 31 of the bracket 30 is a solid iron wire with an arc-shaped cross-section. The arc-shaped shape of the iron wire restricts the shape of the corrugated pipe 10 to also be arc-shaped (approximately circular). The iron wire needs to be made of high-strength mold steel, and its diameter must not be less than 3.5mm; otherwise, the wire will not be strong enough and will easily bend and deform, failing to fully support the rotation of the corrugated pipe 10.

[0052] Existing technologies typically use multiple plastic or stainless steel rods to form a polygon. The more sides a polygon has, the closer its overall shape is to a circular structure. However, since each side corresponds to one plastic or stainless steel rod and one side is driven by one motor, the more sides there are, the more motors there are, resulting in a larger overall size and greater noise, making it difficult to achieve a perfect circular flame display effect.

[0053] This invention uses a single motor 40 to directly drive a bellows 10. One end of the bellows 10 is fixedly connected to the output shaft of the motor 40 and rotates with the output shaft. Compared to a polygonal structure where multiple motors 40 drive multiple plastic or stainless steel rods, this invention solves the noise problem caused by multiple motors 40. The mechanical friction noise of this invention is significantly lower than the friction noise generated by multiple transmission mechanisms on the market. Furthermore, due to the use of fewer parts, the product size can be made very small. While products on the market have a diameter of over 500mm, this invention, by using a single motor 40, can achieve a diameter of 160mm or less.

[0054] In this embodiment, the corrugated pipe 10 is a hollow flexible tube, and the inner wall of the corrugated pipe 10 is attached to the outer wall of the support 30. When the corrugated pipe 10 rotates, its shape remains the same as that of the support 30.

[0055] Specifically, the corrugated pipe 10 is a stainless steel conduit, integrally formed, comprising the stainless steel conduit. The stainless steel conduit is made of 304 or 301 stainless steel and is used as a protective conduit for wires, cables, and signal wires in automated instruments, with specifications ranging from 3mm to 150mm. Ultra-small diameter stainless steel conduits (inner diameter 3mm-25mm) are mainly used for the protection of sensing circuits in precision optical scales and industrial sensors, possessing excellent flexibility, corrosion resistance, high temperature resistance, wear resistance, and tensile strength. The support 30 is made of solid iron wire; during the rotation of the corrugated pipe 10, the structure of the support 30 remains fixed, and the shape of the corrugated pipe 10 remains the same as the shape of the support 30.

[0056] In this embodiment, the simulated flame device also includes a wear-resistant component 50, which is a polytetrafluoroethylene sleeve, a PP sleeve, a PVC sleeve, or a heat-shrinkable sleeve. The wear-resistant component 50 is sleeved on the bracket 30 and is disposed 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.

[0057] Specifically, the bellows 10 is a circular hollow flexible tube with a circular cross-section, allowing it to rotate in any direction and bend into any shape without affecting its rotation. The wear-resistant part 50 is a polytetrafluoroethylene (PTFE) sleeve, PP sleeve, PVC sleeve, or heat-shrinkable sleeve, which acts as a filler on the outer surface of the support 31. The outer surface of the wear-resistant part 50 contacts the inner surface of the bellows 10, reducing the gap between the support 31 and the bellows 10. This prevents vibration, shaking, and friction caused by gaps during rotation and also avoids noise generation. The function of the wear-resistant part 50 is to reduce the frictional noise of rotation, addressing the noise problem, which includes not only the noise from the motor itself but also rotational noise. Optionally, lubricating grease or other lubricating products can be applied between the wear-resistant part 50, the bellows 10, and the support 30 to further reduce friction and noise. Wear-resistant part 50 is fitted on bracket 30 and fixedly connected to bracket 30. When bellows 10 rotates, wear-resistant part 50 and bracket 30 remain stationary. Wear-resistant part 50 has good wear resistance, which avoids bellows 10 directly contacting bracket 30 and causing wear.

[0058] like Figures 2 to 4As shown, in this embodiment, the wear-resistant component 50 is sleeved on the support portion 31 of the bracket 30, and the bellows 10 is sleeved on the wear-resistant component 50; the wear-resistant component 50 is fixedly connected to the support portion 31 of the bracket 30, the inner wall surface of the bellows 10 contacts the outer wall surface of the wear-resistant component 50, and the wear-resistant component 50 is used to reduce the frictional force from the wear-resistant component 50 when the bellows 10 rotates; the shape of the wear-resistant component 50 is the same as the shape of the support portion 31 of the bracket 30, and the bellows 10 continuously bends and deforms during rotation to maintain its... The shape of the support part 31 is the same as that of the bracket 30; the bellows 10 is a hollow sleeve, one end of the support part 31 extends into the bellows 10 along its axial direction, and the other end of the support part 31 is fixedly connected to the support leg 32 and fixed together to 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 by the support part 31, and there is a distance between the end of the support part 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 support leg 32. The motor 40, the bracket 30, and the wear-resistant part 50 are all relatively fixed, only the output shaft of the motor 40 rotates, driving the bellows 10 and the reflector 20 to rotate together.

[0059] In another embodiment of this invention, the corrugated pipe 10, in addition to being a hollow flexible tube (i.e., the corrugated pipe 10 only includes the pipe body), is as follows: Figure 5 As shown, the corrugated pipe 10 may also include a pipe body 11 and an elastic element 12. One end of the pipe body 11 is fixedly connected to the motor 40, and the other end of the pipe body 11 is sleeved on the bracket 30. The elastic element 12 is installed on the outer side, inner side, or inside the pipe wall of the pipe body 11 to provide a restoring force for shape recovery when the pipe body 11 rotates. The material of the pipe body 11 can be a soft and elastically deformable material, such as rubber.

[0060] Specifically, the elastic element 12 can be a spring. Utilizing the flexibility of the elastic element 12, the tube body 11 is wound around the outer or inner wall surface of the tube body 11. Optionally, the elastic element 12 can also be embedded inside the wall of the tube body 11. The elastic element 12 gives the tube body 11 high axial elasticity. When the bellows 10 is not installed on the support 30, under the reset action of the elastic element 12, the bellows 10 is in a state of... Figure 5 (a) shows the straightened state. When the bellows 10 is mounted on the support 30, the bellows 10 is in the straightened state. Figure 5(b) In the bent state shown, the motor 40 drives the bellows 10 to rotate axially. When the entire bellows 10 undergoes an arc-shaped bend under the constraint and pressure of the support 30, the elastic element 12 can self-adaptively deform, reducing the inner ring diameter and increasing the outer ring diameter, while the bellows 10 can still rotate normally. The basic principle utilizes the variability of the elastic element 12. When in a bent state, the pitch on the inner side of the arc of the elastic element 12 is further compressed, and the pitch on the outer side of the arc of the elastic element 12 is further increased. During rotation, the elastic element 12 changes from the inner ring diameter to the outer ring diameter, and the pitch of the elastic element 12 increases from small to large. When the outer diameter changes to the inner diameter, the elastic element 12 changes from the outer ring diameter to the inner ring diameter, and the pitch of the elastic element 12 decreases from large to small. In other words, regardless of how the shape of the bellows 10 changes, the elastic element 12 can automatically adjust its pitch as the bellows 10 rotates. This allows the bellows 10 to solve the rotation problem under different shapes, not only for curved shapes, but also for brackets 30 with complex shapes such as circles, polygons, and multi-fold lines.

[0061] 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 circular, following the support 30. The distance between the bellows 10 and the imaging plate 61 (imaging screen) is uniform.

[0062] In this embodiment, the simulated flame device also includes a light-blocking plate 62, which is fixedly connected to the housing 60. The light-blocking plate 62 and the imaging plate 61 are respectively disposed on both sides of the corrugated pipe 10. The light-blocking plate 62 is used to block light from interfering with the imaging plate 61.

[0063] In this embodiment, the bracket 30 is arc-shaped and the bellows 10 is also arc-shaped. The motor 40, bracket 30 and bellows 10 form a ring. The imaging plate 61 is arranged around the outer ring of the ring, and the light-blocking plate 62 is arranged in the inner ring of the ring.

[0064] In this embodiment, the simulated flame device also includes a support member 63. The bottom of the support member 63 is fixedly mounted on the housing 60. The support member 63 is used to support the bellows 10, help limit the shape of the bellows 10, and prevent the bellows 10 from deforming during rotation.

[0065] Specifically, the simulated flame device has a compact structure. The motor 40, bracket 30, wear-resistant parts 50, and corrugated pipe 10 form a circle. A light-blocking plate 62 is installed inside the circle, and an imaging plate 61 surrounds the circle. The overall size of the product is reduced to a diameter of 160mm or less, which greatly reduces the space occupied by the product compared to existing technologies.

[0066] On the other hand, since this embodiment uses only one motor 40 and one bellows 10, the overall number of components used is less, and therefore the noise generated is also less.

[0067] In this embodiment, the simulated flame device also includes a light source 64, which is fixedly connected to the housing 60. The light emitted by the light source 64 illuminates the reflector 20, and the imaging plate 61 is disposed in the path of the light reflected from the reflector 20.

[0068] Specifically, the reflector 20 is fixed to the corrugated pipe 10, and the reflector 20 rotates synchronously with the corrugated pipe 10, forming a ring-shaped rotation effect. The reflector 20 can be evenly distributed on the corrugated pipe 10. Around the reflector 20, a ring of light sources 64 is provided. The light sources 64 consist of multiple sets of gold LED beads, emitting light similar in color to flames. The LED beads are 3030 LEDs with a power of 0.5W. The light sources 64 are fixedly mounted on the housing 60. An imaging plate 61 is fixedly mounted on the outermost ring of the housing 60. The imaging plate 61 can be a semi-transparent brown color. In this embodiment, the LED beads are preferably 3030 LEDs, but not necessarily limited to this model; 5050 LEDs with a power of 0.5W or other combinations of models and powers can also be used. Different models or powers of LED beads produce different light effects; the color, power, and brightness of the lamp will significantly affect the flame effect.

[0069] When using the simulated flame device, the light emitted by the light source 64 shines onto the reflector 20. The reflector 20 reflects the light through its mirror surface, projecting the light onto the imaging plate 61 to form an image. The imaging plate 61 displays the shape of the reflector 20, which is flame-shaped. The reflector 20 can be made of PET hot-dip galvanized aluminum film with a thickness within 0.1mm, which can reflect the light from the LED beads. After light reflection, the image projected onto the imaging plate 61 creates a flame effect. 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.

[0070] The advantage of this invention lies in the use of a flexible corrugated tube 10 for rotation. Compared to commonly used plastic or iron rods, the flexible corrugated tube 10 can be bent into any shape. During rotation, the support part 31 of the bracket 30 holds the corrugated tube 10 in place, ensuring it maintains the shape defined by the bracket 30. The legs 32 of the bracket 30 are fixedly connected to the housing 60. This design prevents the bracket 30 from shaking or moving, thus avoiding any impact on the corrugated tube 10 and preventing poor imaging. Throughout the process, to minimize or avoid the influence of light from the opposite direction, a light-blocking plate 62 is added. The light-blocking plate 62 has a circular structure, resembling a circular sleeve, and is vertically fixed to the housing 60. The light-blocking plate 62 is located within the inner ring of the corrugated tube 10. The light-blocking plate 62 can be made of black opaque sheet metal and welded to the housing 60 to prevent ghosting and other problems caused by multiple reflections of light.

[0071] It should be noted that when a larger annular simulated flame is required, the length of the bellows 10 can be increased and the diameter of the support 31 can be enlarged to meet the requirements of a larger size. The diameter of the simulated flame device can be increased or decreased adaptively by changing the diameter of the support 31 and the length of the bellows 10. Not only can it be increased, but it can also be decreased; the structure of this embodiment has proven that the diameter of the simulated flame device can be reduced to 160mm or less. This utility model mainly addresses the transmission problem by utilizing the characteristics of the bellows 10. It should be pointed out that the effects of the following other embodiments also fall within the protection scope of this utility model.

[0072] This invention can be combined with a heating device to create a circular simulated flame enclosure.

[0073] like Figure 6 As shown, the second embodiment of this utility model provides a simulated flame device, the general structure of which is the same as that of the first embodiment. The difference is that in this embodiment, the bellows 10 is an elastic element, specifically a spring. The bellows 10 is sleeved on the bracket 30 and undergoes 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 the shape of the bracket 30.

[0074] Bellows 10 adopts as follows Figure 6 Compared to the first embodiment, the spring structure shown in this embodiment has a simpler and more direct connection. Regardless of the type of spring used, such as a molded spring, synthetic spring, alloy spring, or plastic-coated spring, its function and purpose are to solve the rotation problem of a circular shape. Any structural changes and adjustments to the spring structure fall within the protection scope of this utility model, with the aim of solving the rotation problem. Such flexible rotation is always within the protection scope of this utility model.

[0075] The third embodiment of this utility model 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 lies in that the bellows 10 in this embodiment is a spring, and both ends of the bellows 10 also include connectors 13. The connectors 13 are used to connect to 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. The connectors 13 are sleeves with an opening in the middle. The support part 31 of the bracket 30 extends into the bellows 10 through the opening. The support part 31 shapes the structure of the bellows 10, thus forming a circular rotating component assembly. This method achieves circular rotation and also realizes the rotation effect. The reflector 20 is fixed on the sleeve. The side of the sleeve has an opening groove along its circumference, which can be used to fix the reflector 20. This is a deformation result of the bellows 10, which is a multi-segment deformation and also falls within the protection scope of this utility model.

[0076] like Figure 8 As shown, the fourth embodiment of this utility model provides a simulated flame device, whose general structure is the same as that of the first embodiment. The difference lies in that the support part 31 of the bracket 30 (not shown in the figure) is a multi-fold line shape formed by multiple bends of a straight line. The support part 31 includes five straight sections, with the included angle between adjacent straight lines being the same, and the bends forming an approximately circular arc regular polygon shape. The corrugated pipe 10 includes multiple flexible tubes and multiple rigid tubes connected in series, wherein the flexible tubes and rigid tubes are sequentially fixedly connected to each other. The rigid tubes are straight tubes, responsible for forming the straight sections of the multi-fold line, while the flexible tubes are bent tubes, responsible for bending and twisting with the corrugated pipe 10 as a whole when the corrugated pipe 10 rotates, so that the corrugated pipe 10 as a whole maintains the multi-fold line shape.

[0077] like Figure 8 As shown, the output shaft of the motor 40 is straight. The first flexible section of the corrugated pipe 10 is sleeved on the output shaft of the motor 40. After the first flexible section is bent, it is connected to the second rigid section. The other end of the rigid section is then connected to the third flexible section. After the third flexible section is bent, it is connected to the next rigid section. Each flexible section is bent at the same angle in one direction. Multiple flexible sections and multiple rigid sections form a corrugated pipe 10 with a multi-fold line shape.

[0078] The bottom of the support member 63 is fixedly mounted on the housing 60. The rigid tube is mounted on the support member 63 and can rotate on the support member 63. The support member 63 is used to restrict the position of the rigid tube when the bellows 10 rotates, so that the overall shape of the bellows 10 remains unchanged. The rigid tube can be mounted on the support member 63 in two ways: either by opening a through hole in the support member 63 and passing the rigid tube through the through hole, with the diameter of the through hole being slightly larger than the diameter of the rigid tube; or by having the support member 63 clamp the rigid tube, with the diameter of the clamp being slightly larger than the diameter of the rigid tube.

[0079] The reflector 20 (not shown in the figure) is mounted on the corrugated pipe 10. It can be mounted on a rigid pipe or a flexible pipe. When the corrugated pipe 10 rotates, the reflector 20 rotates accordingly.

[0080] In this embodiment, a near-circular simulated flame effect is simulated by a polygonal corrugated pipe 10, which rotates on the support member 63 under the drive of the motor 40.

[0081] Multiple flexible and rigid pipes are connected in series, and then a single motor 40 drives the aforementioned components to rotate. The purpose of this is to use flexible pipes as corner connections while reducing product size. In this embodiment, the power is output by the motor 40, and the flexible pipe of the corrugated pipe 10 serves as the transmission node, with the fundamental purpose of solving the transmission problem. By using the flexible bend of the corrugated pipe 10 as a transfer connection, the size of the product can be significantly reduced, replacing the existing connection structure where multiple motors 40 drive multiple sides separately with a smaller corrugated pipe 10.

[0082] Large-sized products on the market typically use a polygonal structure with multiple motors and over 40 straight rods. However, because each side requires a separate motor, the product size cannot be reduced. In this embodiment, a bellows 10 is used for transmission in the curved section, allowing a single motor to drive the bellows 10, thus solving the problems of the prior art. This embodiment replaces the rigid shaft-rotating polygon with a flexible connection transmission form using arc segments or similar shapes, allowing the bellows 10 to deform and rotate at any shape and angle.

[0083] In summary, this embodiment of the 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, thereby achieving the effect of simulating the constantly changing flickering light of a flame. Moreover, the bracket 30 and the bellows 10 are highly malleable and can be set into various shapes. In particular, the imaging distance of the arc is equal, the flame effect is realistic and there are no shadows. A single motor 40 can drive the bellows 10, resulting in less mechanical friction and vibration, lower noise, and a compact structure.

[0084] Moreover, the bracket 30 can be arc-shaped, wave-shaped, spiral-shaped, or multi-fold line-shaped, making it suitable for designing simulated flame devices of different shapes.

[0085] Furthermore, the corrugated pipe 10 includes a pipe body 11 and an elastic element 12. The elastic element 12 is used to assist the pipe body 11 in undergoing elastic deformation when rotating, so as to always keep it in contact with the support 30 and keep the shape of the corrugated pipe 10 unchanged.

[0086] Furthermore, the simulated flame device also includes a wear-resistant component 50, which is a polytetrafluoroethylene sleeve. The wear-resistant component 50 is sleeved on the bracket 30 and is located 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.

[0087] Furthermore, the simulated flame device also includes an imaging plate 61, a light-blocking plate 62, and a light source 64. The bracket 30 is arc-shaped, and the corrugated pipe 10 is also arc-shaped. The motor 40, bracket 30, and corrugated pipe 10 form a ring. The imaging plate 61 is arranged around the outer ring of the ring, and the light-blocking plate 62 is arranged in the inner ring of the ring. The light emitted by the light source 64 shines on the reflector 20, and the imaging plate 61 is positioned in the path of the light reflected from the reflector 20.

[0088] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
