[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0052] See also Figure 1 and Figure 2 The embodiment of the present application proposes a KD electric fireplace 1 with adjustable components, including a shell 10, a flame simulation device 20, a heating device 40 and an adjustment component 30.

[0053] by Figure 1 The coordinate system in , defines a height direction ZZ, a front-back direction YY, and a left-right direction XX, and the height direction ZZ, the front-back direction YY, and the left-right direction XX are arranged perpendicular to each other.

[0054] The housing 10 is provided with a mounting surface 140 and a projection surface 150. The housing 10 may be formed with an assembly groove (not shown) with at least a front opening, and the mounting surface 140 and the projection surface 150 are both located in the assembly groove. Figure 1 , exemplarily, openings may be provided on the front side and the left and right sides of the assembly slot.

[0055] In some embodiments, see Figure 1 and Figure 2, the housing 10 may include a mounting plate 110, a back plate 120 and a top plate 130. The mounting plate 110 and the top plate 130 extend in the horizontal direction and are spaced apart in the height direction ZZ. The back plate 120 extends in the height direction ZZ, and the mounting plate 110 and the top plate 130 are connected to the opposite sides respectively. With such arrangement, after the mounting plate 110, the back plate 120 and the top plate 130 are installed and fixed, they can form an assembly groove together, and can also form an installation surface 140 and a projection surface 150. It can be understood that the above-mentioned mounting surface 140 can be formed on the top of the mounting plate 110, and the projection surface 150 can be formed on the inner side of the back plate 120. Of course, in some other embodiments, a projection plate can also be installed in the assembly groove, and the projection surface 150 can be formed on the projection plate.

[0056] See also Figures 1 to 4 The flame simulation device 20 includes a base 210, a simulated fuel bed 220, a reflective component 230, and a light source (not shown in the figure). The base 210 is mounted on the mounting surface 140, and has a light-transmitting portion 240 on the rear side. The simulated fuel bed 220 is mounted on the base 210, and an assembly cavity 260 is formed with the base 210. The reflective component 230 and the light source are both mounted in the assembly cavity 260. The reflective component 230 is used to reflect or refract the light emitted by the light source. The refracted or reflected light passes through the light-transmitting portion 240 and is projected onto the projection surface 150, so as to generate an image of a flame on the projection surface 150.

[0057] It should be noted that, during the operation of the embodiment of the present application, under the action of the light source, the simulated fuel bed 220 will produce an effect similar to flames, thereby creating a simulated flame effect. The simulated fuel bed 220 includes but is not limited to artificial firewood, stone, charcoal, etc., and is mainly used to simulate, for example, the texture and color of firewood, the shape and gloss of stone, etc. Here, the present application does not limit the specific form of the simulated fuel bed 220.

[0058] See also Figure 1 and Figure 2 The heating device 40 is installed in the assembly groove. The heating device 40 includes a housing assembly 410, a fan 420 and a heating element 430. The housing assembly 410 is provided with an air duct and a return air port 440 and an air outlet 450 connected to the air duct. The fan 420 and the heating element 430 are installed in the air duct, and the heating element 430 is located on the air outlet side of the fan 420. When working, the fan 420 drives the external air flow from the return air port 440 into the air duct. The temperature of the air flow is adjusted after passing through the heating element 430, and the air flow flows to the indoor environment through the air outlet 450, thereby achieving the purpose of heating the air in the space.

[0059] In some embodiments, the air outlet 450 is oriented in the horizontal direction. Since the air outlet is oriented in the horizontal direction, the air flow can be more stable, unnecessary air flow disturbance and noise can be reduced, and the working efficiency and comfort of the system can be improved. Optionally, in some embodiments, the air outlet 450 is oriented downward. For example, in some installation environments, the demand for side air outlet cannot be met, and a downward air outlet solution is required. By using a variety of different installation accessories and interfaces, the direction of the air outlet 450 can be flexibly adjusted to meet the actual needs of different users or different scenarios.

[0060] See also Figure 1 , Figure 2 as well as Figure 8 The adjusting component 30 is installed on the mounting surface 140 and supports the base 210 to lift the rear side of the base 210 from the mounting surface 140. The adjusting member 310 is connected to different positions of the base 210, or the adjusting member 310 is rotatably connected to the base 210, or the supporting height of the adjusting member 310 is adjustable, so that the base 210 obtains different supporting angles. In this way, the adjusting component 30 can support the rear side of the base 210 at different angles, so that the height of the flame image on the projection surface 150 can be adjusted by adjusting the light transmission angle of the light transmission part 240.

[0061] It should be noted that the connection forms between the above-mentioned adjusting member 310 and the base 210 can be arranged in combination or can be arranged selectively.

[0062] Based on the electric fireplace 1 of the embodiment of the present application, the present application designs an adjustment component 30 so that the base 210 can be tilted or lifted at different angles on the mounting surface 140, so that the tilt angle of the light-transmitting portion 240 can be adjusted, and then the angle at which light is transmitted from the light-transmitting portion 240 can be adjusted, so that the position and height of the flame image on the projection surface 150 can be adjusted. In the present application, the user can adjust the angle of the base 210 according to his or her preferences and needs, and customize the height of the flame image on the projection surface 150. This personalized experience enables the user to adjust the flame effect according to the environment and mood, and enhances the interactivity and attractiveness of the product. At the same time, by adjusting the light transmission angle of the light-transmitting portion 240, the adjustment component 30 can change the brightness and clarity of the flame image on the projection surface 150. In addition, this adjustment method is simple and intuitive to operate, and the user can adjust the angle of the base 210 through easy operation to adjust the flame effect, thereby improving the user-friendliness and convenience of use of the product.

[0063] The following is combined with Figures 5 to 7 , the adjusting member 310 and the connection form between the adjusting member 310 and the base 210 are specifically introduced.

[0064] The adjusting member 310 is connected to different positions of the base 210 so that the base 210 can obtain different support angles. Figure 8 a, when the adjusting component 30 is supported at the middle of the base 210, the angle α of the flame simulation device 20 supported is greater than the angle β of the flame simulation device 20 supported when the adjusting component 30 is supported at the rear of the base 210, that is, the different positions of the adjusting component 310 and the base 210 refer to different positions in the front-to-back direction YY. In this way, by moving the adjusting component 310 relative to the flame simulation device 20 in the front-to-back direction YY, the base 210 can obtain different supporting angles.

[0065] In some embodiments, the adjusting member 310 includes a supporting portion 312 and a first fixing portion 311 connected to one side of the supporting portion 312, the first fixing portion 311 is relatively fixed to the base 210, and the other side of the supporting portion 312 is abutted against the mounting surface 140. During installation, the first fixing portion 311 is relatively fixed to different positions of the base 210, so as to adjust the height and angle of the supporting portion 312 supporting the base 210, and further adjust the height of the flame image on the projection surface 150.

[0066] Furthermore, in order to facilitate relative fixation of the adjustment member 310 and the base 210 at different positions, the first fixing portion 311 is provided with a first adjustment structure 314, and the base 210 is provided with a second adjustment structure (not shown in the figure). The first adjustment structure 314 and the second adjustment structure are fixed together, so that the first fixing portion 311 can be relatively fixed at different positions of the base 210.

[0067] In order to improve the stability of the installation of the adjusting member 310 and the housing 10, the adjusting member 310 also includes a second fixing portion 313, and the second fixing portion 313 is connected to the end of the supporting portion 312 away from the first fixing portion 311. By providing the second fixing portion 313, the supporting points of the adjusting member 310 supported on the mounting surface 140 can be increased, so that the shaking and loosening of the adjusting member 310 during the supporting process can be reduced, and the connection between the adjusting member 310 and the housing 10 can be ensured to be more firm and reliable. In addition, the second fixing portion 313 can distribute the pressure during the installation process more evenly. In this way, the risk of local stress concentration can be reduced, and the overall structural strength and durability of the adjusting member 310 and the housing 10 can be improved.

[0068] In order to further improve the stability of the connection between the adjusting member 310 and the housing 10, the second fixing portion 313 is provided with a third adjusting structure 315, and the mounting surface 140 is provided with a fourth adjusting structure (not shown in the figure), and the third adjusting structure 315 is fixed in cooperation with the fourth adjusting structure. In this way, when the adjusting member 310 and the base 210 are relatively fixed at different positions, the adjusting member 310 and the mounting surface 140 can be relatively fixed at different positions by the third adjusting structure 315 and the fourth adjusting structure, thereby improving the stability of the adjusting member 310 supporting the base 210.

[0069] In order to improve the stability of the installation of the adjustment member 310 with the housing 10 and the base 210, the adjustment assembly 30 of the embodiment of the present application further includes a locking device (not shown in the figure), and the locking structure of the locking device includes a first locking member and a second locking member. The first locking member is used to fix the first adjustment structure 314 and the second adjustment structure, so as to relatively fix the adjustment member 310 with the base 210; the second locking member is used to match and connect the third adjustment structure 315 and the fourth adjustment structure, so as to relatively fix the adjustment member 310 with the mounting surface 140. The first locking member and the second locking member can be screws, bolts or bolts matched with nuts. In other embodiments, the first locking member and the second locking member can also be snap fasteners, etc., so it is not limited to this.

[0070] The first fixing portion 311, the supporting portion 312 and the second fixing portion 313 of the embodiment of the present application can all be plate-like structures, that is, the first fixing portion 311, the supporting portion 312 and the second fixing portion 313 can be formed on a sheet metal part through a stamping process, a bending process or other casting process. This processing method is simple, low-cost, and has better integrity and stability.

[0071] In some embodiments, the second adjustment structure is at least two adjustment holes, which are arranged at intervals in the front-to-back direction YY, and the first adjustment structure 314 is fixedly matched with one of the at least two adjustment holes. The fourth adjustment structure is at least two mounting holes, which are arranged at intervals in the front-to-back direction YY, and the third adjustment structure 315 is fixedly matched with one of the at least two mounting holes.

[0072] Combining the first fixing portion 311 and the second fixing portion 313 as sheet metal parts, it is convenient to arrange the adjustment hole and the mounting shell 411 at intervals in the front-to-back direction YY. During installation, the second adjustment structure is fixedly matched with at least one of the two adjustment holes to relatively fix the adjustment member 310 at different positions of the base 210. When performing the adjustment operation, it is only necessary to adjust the second adjustment structure to align with the adjustment holes at different positions, and then use the first locking member to install and fix it, and then adjust the third adjustment structure 315 to align with the corresponding mounting hole, and use the second locking member to lock the third adjustment structure 315 with the mounting hole. This adjustment method is simple, the fixing method is reliable, and it is easy to fix after adjustment. In other embodiments, the second adjustment structure and the third adjustment structure 315 can also be designed in the form of an assembly hole. Of course, the second adjustment structure and the third adjustment structure 315 can also be designed as at least two assembly holes.

[0073] In some embodiments, one of the first adjustment structure 314 and the second adjustment structure is a first adjustment groove, and the other is connected to the different positions of the first adjustment groove, so as to relatively fix the adjustment member 310 at different positions of the base 210. One of the third adjustment structure 315 and the fourth adjustment structure is a second adjustment groove, and the other is connected to the different positions of the second adjustment groove. When the first adjustment structure 314 or the second adjustment structure is adjusted to the first adjustment groove, the first locking member is used to fix the first adjustment structure 314 or the second adjustment structure to the corresponding position of the first adjustment groove. Then, the second locking member is used to fix the third adjustment structure 315 or the fourth adjustment structure to the corresponding position of the second adjustment groove.

[0074] In some embodiments, the first adjustment structure 314 is a first buckle 3141, and the second adjustment structure is at least two first slots, which are spaced apart in the front-to-back direction YY. By snapping the first buckle 3141 into different first slots, the adjustment member 310 can be relatively fixed at different positions of the base 210. Alternatively, the first adjustment structure 314 is at least two first slots, and the second adjustment structure is the first buckle 3141. The third adjustment structure 315 is a second buckle, and the fourth adjustment structure is at least two second slots, which are spaced apart in the front-to-back direction YY. By snapping the second buckle into different second slots, the adjustment member 310 can be relatively fixed at different positions of the mounting surface 140. Alternatively, the third adjustment structure 315 is at least two second slots, and the fourth adjustment structure is a second buckle.

[0075] In some embodiments, see Fig. 9One end of the adjusting member 310 is rotatably connected to the base 210. By adjusting the angle between the adjusting member 310 and the base 210, the base 210 can be supported at different angles. It is understandable that the adjusting member 310 can be a plate, which is rotatably connected to the base 210 via a rotating shaft 318. A damping structure can be provided on the rotating shaft 318 to adjust the swing angle between the adjusting member 310 and the base 210. Please refer to Fig. 9 a. When the included angle between the adjusting member 310 and the base 210 is small, the angle α of the flame simulation device 20 supported by the adjusting member 310 is also relatively small, and when the included angle between the adjusting member 310 and the base 210 is large, the angle β of the flame simulation device 20 supported by the adjusting member 310 is also relatively large.

[0076] In some embodiments, the adjusting member 310 includes a connecting portion 3161 and a first mounting portion 3162 and a second mounting portion 3163 that are rotatably connected to opposite sides of the connecting portion 3161, respectively. The first mounting portion 3162 is connected to the mounting surface 140, and the second mounting portion 3163 is connected to the base 210. The rotation angle between the first mounting portion 3162 and the connecting portion 3161 is adjustable, and the rotation angle between the second mounting portion 3163 and the connecting portion 3161 is adjustable to adjust the support height of the adjusting member 310. In the present application, by adjusting the rotation angle between the first mounting portion 3162 and the connecting portion 3161 and the second mounting portion 3163 and the connecting portion 3161, the support height of the adjusting member 310 can be adjusted as needed, so that the adjusting member 310 can support the base 210 at different angles.

[0077] It should be noted that the first mounting portion 3162 and the connecting portion 3161 can be rotatably connected via the rotating shaft 318, and the second mounting portion 3163 and the connecting portion 3161 can be rotatably connected via the rotating shaft 318. It is understandable that a damping structure can be provided on the rotating shaft 318, and the rotating angle between the first mounting portion 3162 and the connecting portion 3161 and the rotating angle between the second mounting portion 3163 and the connecting portion 3161 can be adjusted by the damping structure.

[0078] Furthermore, in order to improve the stability of the connection between the adjustment member 310 and the base 210 and the mounting surface 140, the first mounting portion 3162 and the second mounting portion 3163 can both be provided with an adjustment structure in the form of the first fixing portion 311 and the second fixing portion 313, and the mounting surface 140 and the base 210 can also be provided with a corresponding adjustment structure in the form described above.

[0079] In some embodiments, the adjusting member 310 includes a first supporting member 317 and a second supporting member 319. One end of the first supporting member 317 is connected to the base 210, and the other end is movably connected to the second supporting member 319. The end of the second supporting member 319 away from the first supporting member 317 is connected to the mounting surface 140. The supporting height of the adjusting member 310 is adjusted by movably connecting the first supporting member 317 and the second supporting member 319, so that the adjusting member 310 can support the base 210 at different angles.

[0080] It should be noted that the movable connection between the first support member 317 and the second support member 319 includes, but is not limited to, threaded connection, snap connection, sliding connection, etc. For example, a plurality of first threaded holes spaced apart in the height direction may be provided on the first support member 317, and a second threaded hole may be provided on the second support member 319, and the adjusting member 310 may have different supporting heights by fixing the second threaded hole relative to different threaded holes.

[0081] Furthermore, the first support member 317 includes a first support section 3171 and a first assembly section 3172, and the second support member 319 includes a second support section 3191 and a second assembly section 3192. The first assembly section 3172 is connected to one side of the first support section 3171 and is connected to the base 210; the second assembly section 3192 is connected to one side of the second support section 3191 and is connected to the mounting surface 140. The first support section 3171 and the second support section 3191 are relatively fixed at different positions, so that the adjustment member 310 can support the base 210 at different angles.

[0082] In order to improve the flexibility of adjusting the first support section 3171 and the second support section 3191, the first assembly section 3172 and the first support section 3171 can be rotatably connected via the rotating shaft 318, and the second assembly section 3192 and the second support section 3191 can be rotatably connected via the rotating shaft 318. It can be understood that a damping structure can be provided on the rotating shaft 318, and the rotation angle between the first assembly section 3172 and the first support section 3171 can be adjusted, and the rotation angle between the second assembly section 3192 and the second support section 3191 can be adjusted.

[0083] Furthermore, in order to improve the stability of the connection between the adjustment member 310 and the base 210 and the mounting surface 140, the first support segment 3171 and the second support segment 3191 can be provided with an adjustment structure in the form of the above-mentioned first fixing portion 311 and the second fixing portion 313, and the mounting surface 140 and the base 210 can also be provided with a corresponding adjustment structure in the form mentioned above.

[0084] In order to improve the stability of the adjusting member 310 supporting the base 210, the number of the adjusting members 310 in the embodiment of the present application is at least two, and the at least two adjusting members 310 are respectively supported on opposite sides of the base 210. Of course, in other embodiments, the number of the adjusting members 310 can also be 3, 4, 5, etc., and the adjusting members 310 are arranged on the base 210 at intervals.

[0085] It is further explained that in order to improve the stability of the installation of the base 210, the front side of the base 210 is relatively fixed to the installation surface 140. Specifically, a baffle plate can be provided on the installation surface 140, and the front side of the base 210 abuts against the baffle plate, so that the rear side of the base 210 can be easily lifted, and the position of the adjustment member 310 fixed relatively to the base 210 can be adjusted, or the angle between the adjustment member 310 and the base 210 can be adjusted, or the support height of the adjustment member 310 can be adjusted.

[0086] In some embodiments, see Figure 4 The reflective assembly 230 further includes a reflective structure 231 and a driving device 232. The reflective structure 231 includes a shaft 2311 and a plurality of reflectors 2312. The plurality of reflectors 2312 are irregularly mounted on the shaft 2311, and the reflector 2312 has a reflective surface. The reflector 2312 can be a reflective sheet in a plane shape, and the reflector can be in various shapes, such as square, circular, triangular, etc. Among them, the driving device 232 drives the reflective structure 231 to rotate around the shaft 2311 so that the plurality of reflective surfaces have different reflective angles. By making the plurality of reflectors 2312 have different reflective angles, the reflected light can be made more diversified and uniform. In this way, the reflection effect of the light can be enhanced, so that the entire reflective assembly 230 can more effectively reflect the light to the target area and improve the lighting effect. The driving device 232 can control the reflective structure 231 to rotate around the shaft 2311 and adjust the angles of the plurality of reflectors 2312. In this way, the reflection angle can be adjusted at any time according to actual needs, so that the reflection component 230 has greater flexibility and adjustability to adapt to different scenes and needs.

[0087] The base 210 includes a support plate 211 and two side plates 212, wherein the two side plates 212 are mounted on the support plate 211 and are spaced apart in the left-right direction XX. The two side plates 212, the support plate 211 and the simulated fuel bed 220 surround an assembly cavity 260 (not shown in the figure). The reflective assembly 230 can be mounted on the two side plates 212. The support plate 211 includes a bottom plate 2111 and a tail plate 2112, wherein the tail plate 2112 is connected to one side of the bottom plate 2111 and is arranged at an angle with the bottom plate 2111, wherein the tail plate 2112 is provided with a light-transmitting portion 240.

[0088] In some structural forms, the light-transmitting portion 240 is a through-groove structure, which is simple to process. Of course, in other embodiments, the light-transmitting portion 240 can be formed on a light-transmitting member such as a plastic plate, a glass plate, etc. installed on the support plate 211 .

[0089] In some embodiments of this application, please refer to Fig.10 , Fig.13 and Fig.14 The housing assembly 410 of the heating device 40 includes a mounting housing 411, a volute 412, an air duct housing 413, a protective net 415 and an assembly plate 414. The mounting housing 411 is provided with a return air port 440 and an air outlet 450. The mounting housing 411 includes an upper housing 4111 and a lower housing 4112. The upper housing 4111 and the lower housing 4112 are connected and jointly define the air outlet 450. In addition, the return air port 440 can be provided in the lower housing 4112, or in the upper housing 4111, or in both the upper housing 4111 and the lower housing 4112. The volute 412 and the air duct housing 413 are connected and both are installed in the mounting housing 411. The mounting shell 411, the volute 412 and the air duct shell 413 define an air duct together, the fan 420 is mounted on the volute 412, the heating element 430 is mounted on the air duct shell 413, and the protective net 415 is mounted on the mounting shell 411 and located on the air outlet side of the heating element 430. The assembly plate 414 is connected to the outside of the mounting shell 411 and fixedly connected to the outer shell 10, so as to relatively fix the mounting shell 411 in the mounting groove 540.

[0090] With such arrangement, the design of the volute 412 and the air duct housing 413 can effectively guide the air flow and enhance the effect of the electric fireplace 1 on heating the air in the space. Moreover, the present application installs the fan 420 in the volute 412, installs the heating element 430 in the air duct housing 413, and then relatively fixes the volute 412 and the air duct housing 413. With such arrangement, the fan 420 and the heating element 430 can be installed and maintained relatively independently, which is convenient for users to maintain and clean the equipment. In addition, the setting of the protective net 415 can effectively prevent external debris from entering the interior of the equipment, protect the internal components from damage, and improve the reliability and service life of the equipment.

[0091] See also Fig.13, the air duct shell 413 includes an air guide plate 4131, which is located between the fan 420 and the heating element 430, and is spaced apart from the volute 412, and the spacing between the air guide plate 4131 and the volute 412 gradually increases in the direction away from the fan 420. In this way, a pressure diffusion chamber can be formed between the fan 420 and the heating element 430, and the airflow blown out by the fan 420 can convert part of the kinetic energy into static pressure through the pressure diffusion effect of the pressure diffusion chamber, reduce the wind speed, and then can be efficiently heated by the heating element 430. The pressure diffusion chamber of the embodiment of the present application can change the flow state and speed of the airflow, so that the gas can produce a state of pressure reduction, expansion and dispersion during the flow process, so that the airflow can achieve better distribution and uniformity, and then the airflow will be more stable and gentle when passing through the heating element 430, reducing noise.

[0092] See also Figures 10 to 12 , the embodiment of the present application further includes a front panel 50, which is fixedly connected to the housing 10 and is provided with a through hole 530 connected to the air outlet 450, and the housing assembly 410 is connected to different positions of the housing 10 to adjust the distance between the air outlet 450 and the through hole 530. Specifically, when the distance between the air outlet 450 and the through hole 530 increases, the ventilation path becomes longer, the resistance of air circulation increases, resulting in a decrease in the air outlet speed of the air outlet 450, thereby reducing the amount of air passing through the air outlet 450 per unit time. Conversely, when the distance between the air outlet 450 and the through hole 530 decreases, the ventilation path becomes shorter, the resistance of air circulation decreases, resulting in an increase in the air outlet speed of the air outlet 450, and an increase in the amount of air passing through the air outlet 450 per unit time. The present application can adjust the air volume of the electric fireplace 1 by adjusting the distance between the air outlet 450 and the through hole 530.

[0093] Furthermore, the outer diameter of the through hole 530 is greater than the outer diameter of the air outlet 450. Since the outer diameter of the through hole 530 is greater than the outer diameter of the air outlet 450, the ventilation path is more spacious and the resistance of air circulation is relatively small. This will reduce the wind resistance in the electric fireplace 1, reduce the energy consumption of the system, and improve the ventilation efficiency. In addition, the air flow rate when passing through the through hole 530 can be relatively low, which may reduce the noise generated when the air flows.

[0094] In order to facilitate the adjustment of the distance between the air outlet 450 and the through hole 530, the above-mentioned assembly plate 414 is provided with a travel groove 4141, and different positions of the travel groove 4141 are relatively fixed to the top plate 130. The travel groove 4141 can be fixedly connected to the top plate 130 by threaded fasteners such as screws and bolts. Specifically, after the fastener passes through the travel groove 4141 and is fixed to the top plate 130, the bottom of the assembly plate 414 can be fixed on the head of the fastener, and at this time, the column of the fastener will be partially located in the travel groove 4141. When it is necessary to adjust the distance between the air outlet 450 and the through hole 530 of the heating device 40, it can be done by pushing the mounting shell 411, and in the process of pushing the mounting shell 411, the column of the fastener can slide in the travel groove 4141.

[0095] Please refer again Fig.10 and Fig.11 The front panel 50 includes a plate body 510 and a surrounding plate 520 arranged around the plate body 510. The plate body 510 is provided with a through hole 530. The surrounding plate 520 and the plate body 510 surround a mounting groove 540 and are connected to the housing 10. Among them, at least part of the mounting shell 411 is embedded in the mounting groove 540. The surrounding plate 520 is provided with at least two limiting parts 560 located in the mounting groove 540, and the opposite sides of the mounting shell 411 abut against the limiting parts 560. The mounting shell 411 is embedded in the mounting groove 540, which simplifies the installation process of the front panel 50 and the mounting shell 411. The opposite sides of the mounting shell 411 abut against the limiting parts 560, which can ensure the stable connection between the mounting shell 411 and the front panel 50, and can also prevent the mounting shell 411 from shifting between the mounting shell 411 and the front panel 50 during the adjustment process with the housing 10.

[0096] It can be understood that the heating device 40 and the flame simulating device 20 of the present application are independent modules, so the heating device 40 and the flame simulating device 20 can be installed at different positions of the housing 10. The heating device 40 can be located above or below the flame simulating device 20. In some embodiments of the present application, in order to facilitate the installation of the heating device 40 and the flame simulating device 20 and the projection of the flame simulating device 20, the heating device 40 is located above the flame simulating device 20.

[0097] Further, in order to facilitate the installation of the housing 10 and the front panel 50, please refer to Figure 2The top plate 130 of the embodiment of the present application includes a first plate portion 131 and a second plate portion 132 connected to each other. The first plate portion 131 is connected to the back plate 120 at a side away from the second plate portion 132. The first plate portion 131 is spaced apart from the mounting plate 110, and the second plate portion 132 is spaced apart from the back plate 120. The enclosure 520 is provided with a third fixing portion 550. The top of the enclosure 520 is connected to the bottom of the second plate portion 132, and the third fixing portion 550 is connected to the inner side of the second plate portion 132. In this way, the contact area between the front panel 50 and the top plate 130 can be increased, thereby improving the stability of the installation of the front panel 50.

[0098] Of course, see Figure 8 and Fig. 9 , the heating device 40 of the embodiment of the present application can be located below the flame simulating device 20. The heating device 40 can be installed on the mounting plate 110, and a mounting surface 140 for mounting the flame simulating device 20 is formed on the top of the mounting shell 411, and the adjustment assembly 30 and the flame simulating device 20 are mounted on the mounting surface 140 on the top of the mounting shell 411. Here, the present application does not limit the specific installation form of the heating device 40 and the flame simulating device 20.

[0099] The embodiment of the present application further includes a protective cover, which is connected to the front panel 50 and covers the through hole 530. The protective cover and the front panel 50 can be integrally formed components. In this way, no additional connecting parts or steps are required during installation, which can simplify the installation process and reduce installation time and workload. The protective cover and the front panel 50 are connected as an integrally formed component, which can enhance the stability and rigidity of the entire structure and reduce vibration or looseness that may occur during use.
