Description

Technical Field

[0001] This invention relates to the field of home appliance technology, specifically to a flame-powered fan heater. Background Technology

[0002] Existing flame-shaped fan heaters typically feature heating and simulated flame effects, with some even integrating voice control to enhance the user experience. However, traditional flame-shaped fan heaters suffer from the following issues in voice interaction: they lack simulation of ambient sounds related to flame combustion, such as crackling and burning sounds, preventing users from experiencing a more realistic audiovisual experience of flame combustion and negatively impacting the user experience. Summary of the Invention

[0003] In view of this, the present invention provides a flame-shaped fan heater to solve the problem that users of existing flame-shaped fan heaters cannot obtain a more realistic audio-visual effect of flame combustion, which affects the user experience.

[0004] This invention provides a flame-powered warm air heater, comprising: Main body of the heater; The combustion sound effect module is installed on the main body of the heater via a mounting structure and is used to play simulated flame combustion sounds; The mounting structure includes a mounting base formed on the main body of the heater and open on one side, and a cover that can be detachably installed at the opening; The cover and the mounting base together form a mounting cavity for installing the combustion sound effect module. One end of the cover is inserted into the mounting base, and the other end is fixed to the mounting base by a snap-fit ​​structure. Beneficial effects: The combustion sound module integrated into the main body of the heater can independently play simulated flame sounds, such as crackling and low-frequency burning sounds, enhancing the immersive simulation and providing users with a more realistic audiovisual experience of flame combustion, thus improving the user experience. Furthermore, the installation cavity formed by the mounting base and cover provides an independent and stable installation space for the combustion sound module, avoiding acoustic interference. In addition, the cover uses a connection method where one end plugs into the mounting base and the other end is fixed to the mounting base via a snap-fit ​​structure, ensuring stable and reliable installation, facilitating the installation, replacement, and maintenance of the combustion sound module, increasing assembly efficiency, improving production and after-sales efficiency, and meeting users' requirements for "realism" and "smooth interaction" in smart home applications.

[0005] In one alternative embodiment, one end of the cover is provided with a connector rib, and the mounting base is provided with a corresponding slot for inserting the connector rib.

[0006] Beneficial effects: The plug-in ribs on one end of the cover and the corresponding slots on the mounting base allow for quick pre-positioning during assembly. First, the end of the cover with the plug-in ribs is inserted obliquely into the slot, and then the other end of the cover is pressed into the mounting base for locking and fixing. The cooperation between the plug-in ribs and the slots enables quick pre-positioning in the initial stage of installation, preventing misalignment and improving assembly accuracy and efficiency.

[0007] In one optional embodiment, the snap-fit ​​structure includes a snap-fit ​​fixedly disposed at the other end of the cover and a corresponding snap-fit ​​platform disposed on the mounting base; The buckle and / or the card plate are provided with guide ramps for guiding the buckle to engage onto the card plate.

[0008] Beneficial effects: The design of the guide slope makes the snap-fit ​​process between the buckle and the clamping table smoother, avoids structural damage caused by mechanical jamming, and improves the assembly experience.

[0009] In one alternative embodiment, the cover is provided with a first support rib for engaging with the combustion sound module.

[0010] Beneficial effects: By setting the first support rib on the cover, the first support ribs are tightly abutted against each other, which effectively limits the vibration displacement of the speaker during operation, prevents resonance noise with the surrounding structure, ensures the purity of the flame sound effect, and improves the sound pickup accuracy.

[0011] In one alternative embodiment, the mounting base also has positioning ribs that match the outer periphery of the combustion sound module.

[0012] Beneficial effects: By matching the positioning ribs with the contour of the combustion sound module, the vibration displacement of the combustion sound module during operation is effectively limited, preventing resonance noise with the surrounding structure and ensuring the purity of the flame sound effect. The positioning ribs also ensure that the combustion sound module is accurately and stably positioned in the installation cavity, avoiding the impact on the acoustic output effect due to displacement.

[0013] In one alternative embodiment, the main body of the heater includes a fan assembly, which includes fan blades, a drive motor for driving the fan blades to rotate, and a motor bracket for mounting the drive motor. The motor bracket has an integrally formed first recess, which constitutes a mounting base.

[0014] Beneficial effects: By cleverly utilizing the solid structure of the motor bracket, without adding extra components or occupying space, the first recess integrally formed on the motor bracket provides a space for the combustion sound effect module, achieving a compact structure and integrated functions, and improving space utilization.

[0015] In one alternative implementation, the combustion sound effect module is connected to the main board of the flame heater via a lead wire. The first recess is provided with a wiring hole for the lead wire to pass through, and a wiring structure is also formed on the motor bracket to constrain the direction of the lead wire.

[0016] Beneficial effects: The design of the wiring holes and wiring structure can organize the leads, prevent them from scattering inside the equipment, avoid interference with moving parts (such as fan blades), simplify wiring, and improve safety and reliability.

[0017] In one alternative implementation, the motor bracket includes: Support body; The annular rib is fixedly installed on the main body of the support. The annular rib is located on the outer periphery of the main body of the support and has a reserved gap between it and the outer periphery of the main body of the support. The wiring structure includes: The notch is formed on the annular rib, and the lead wire passes through the notch to the reserved gap; The wire buckle is fixedly installed on the main body of the bracket and located on the outer periphery of the annular rib. The wire buckle, the annular rib, and the main body of the bracket enclose and form a wiring channel. There is a gap opening between the wire buckle and the annular rib for the lead wire to be inserted into the wiring channel. The retaining rib is fixedly installed on the outer wall of the annular rib and is staggered from the wire buckle to prevent the lead wire from coming out of the gap opening.

[0018] Beneficial effects: The wiring structure, through the use of notch grooves, wire clips, and baffles, provides a clear and optimized wiring path for the combustion sound module's leads to the motherboard, reducing signal interference and ensuring the consistency of cable layout in mass production. This makes the wiring path more standardized. The wire clips and baffles design firmly restrain the leads within the wiring channel, allowing the leads to connect directly to the motherboard along the wiring channel, simplifying wiring and preventing them from falling off due to vibration or getting caught in the fan assembly.

[0019] In one alternative implementation, the flame-heated air heater further includes a voice control module, which includes a voice speaker; The main body of the heater also includes a rear shell assembly, which includes a rear shell and a rear air duct located inside the rear shell. The rear air duct has a second recess integrally formed, and a mounting groove for installing a voice speaker is formed in the second recess. The rear cover seals the opening of the mounting groove, and a second support rib is provided on the rear cover at the position corresponding to the second recess for abutting and cooperating with the voice speaker. Beneficial effects: The voice speaker is mounted on the rear air duct, while the combustion sound module is mounted on the motor bracket, achieving dual separation of the voice speaker and flame speaker in both physical location and installation structure. The second support rib on the rear housing provides stable support for the voice speaker, effectively isolating mechanical noise such as fan component vibration and improving the accuracy of voice wake-up and recognition. Furthermore, without adding extra components or occupying additional space, the integrated recess of the rear air duct serves as the mounting slot for the voice speaker, resulting in a robust structure that saves space.

[0020] In one optional embodiment, the main body of the heater further includes a simulated flame module, which includes: The charcoal fire assembly includes a display panel, simulated charcoal, and a light-shielding sheet arranged sequentially from the outside to the inside, with the display panel and the light-shielding sheet forming an installation space to accommodate the simulated charcoal; The lighting assembly is located on the side near the light shield. The lighting assembly includes a light-emitting element and a reflector. The reflector includes a reflector and a stepper motor for driving the reflector to rotate. The reflector rotates under the drive of a stepper motor to reflect the light emitted by the light-emitting element onto the light-shielding plate, so that the simulated charcoal creates the visual effect of burning.

[0021] Beneficial Effects: The charcoal and lighting components simulate the effect of flame combustion, creating a more realistic and dynamic visual experience, enhancing the realism and atmosphere of the visual effect. Furthermore, the charcoal component, combining simulated charcoal, a display panel, and a light-shielding plate, forms a deep "combustion chamber" structure, enhancing the layering and three-dimensionality of the flame. The lighting component, employing a stepper motor and reflectors, allows the reflectors to rotate continuously, dynamically reflecting light emitted from the light source onto the light-shielding plate. This creates a flickering, dimming effect on the simulated charcoal, highly simulating the dynamic light of a real flame, creating a warm, comfortable, and realistic flame atmosphere. This immersive user experience adds a simulated flame visual scene to the heating function, making it more competitive in the market. Additionally, the reflectors prevent direct light from shining into the eyes, instead softening the light through secondary reflection and filtering by the reflectors and light-shielding plate, resulting in more uniform and gentle light, reducing visual stimulation, and making it suitable for prolonged viewing.

[0022] In one alternative implementation, the main body of the heater also includes a housing and a heating element assembly; The housing includes an annular outer shell, a front grille assembly mounted at both ends of the annular outer shell, and a rear shell assembly, wherein the front grille assembly is annular; The charcoal fire assembly is installed in the middle area of ​​the front mesh assembly, and the lighting assembly is located in the cavity formed between the annular outer shell and the rear shell assembly. The front grille assembly includes an annular front grille with several air outlets on it; The heating element assembly is ring-shaped and located inside the casing near the air outlet to heat the airflow at the air outlet.

[0023] Beneficial Effects: By matching the annular heating element assembly with the annular air outlet, the airflow is evenly heated as it passes through, forming a ring-shaped hot air band, expanding the heating range, and resulting in a faster and more uniform increase in indoor temperature. Furthermore, the annular outer shell integrating the front and rear covers, along with the annular layout of internal components, maximizes space utilization, resulting in a compact overall structure that facilitates installation and placement. The front cover design not only forms an annular air outlet but also effectively isolates the user from the heating element, preventing accidental contact and reducing the risk of burns. Air enters through the air inlet on the rear cover, flows through the annular heating element for thorough heating, and is then concentrated and blown out from the annular air outlet, ensuring a smooth path, high heat exchange efficiency, and reduced energy loss. In addition, the annular front cover combined with the charcoal fire assembly creates an appearance similar to a modern fireplace, with an elegant design that meets consumers' aesthetic needs for home appliances and is suitable for various home styles.

[0030] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Existing flame-controlled fan heaters typically feature heating and simulated flame effects, with some models also integrating voice control to enhance user experience. However, traditional flame-controlled fan heaters suffer from the following issues regarding voice interaction: 1. Incomplete simulation experience: The lack of environmental sound simulation of flame combustion, such as crackling and burning sounds, prevents users from having an immersive flame experience, resulting in a significant difference from the effect of real flames.

[0032] 2. Limited voice functionality: Existing products typically only have a single speaker for voice interaction and volume control, and the upper limit of voice control volume is low, which affects the user experience.

[0033] 3. The traditional voice module installation structure on the heater is poorly designed, resulting in low assembly efficiency, poor stability, and affecting the sound output quality.

[0034] 4. Some flame-powered heaters share a speaker for both the voice function and the flame combustion sound effect, resulting in a low volume limit and mixed sound effects.

[0035] The following is combined Figures 1 to 18 The following describes embodiments of the present invention.

[0036] According to an embodiment of the present invention, in one aspect, the present invention provides a flame-shaped fan heater, including a fan heater body 1 and a combustion sound effect module 2. The combustion sound effect module 2 is mounted on the fan heater body 1 via an installation structure and is used to play simulated flame combustion sounds; such as Figure 15 As shown, the installation structure includes a mounting base 11 formed on the main body 1 of the heater and open on one side, and a cover 12 detachably installed at the opening; the cover 12 and the mounting base 11 together form an installation cavity for installing the combustion sound effect module 2, one end of the cover 12 is inserted into the mounting base 11, and the other end is fixed to the mounting base 11 by a snap-fit ​​structure. In the above embodiments, the combustion sound module 2 installed on the main body 1 of the heater can independently play simulated flame combustion sounds, such as crackling sounds and low-frequency combustion sounds, enhancing the immersive simulation and providing users with a more realistic audiovisual experience of flame combustion, thus improving the user experience. Furthermore, by using the mounting cavity formed by the mounting base 11 and the cover 12 to install the combustion sound module 2, an independent and stable installation space is provided, avoiding acoustic interference. In addition, the cover 12, with one end plugged into the mounting base 11 and the other end fixed to the mounting base 11 via a snap-fit ​​structure, not only ensures stable and reliable installation but also facilitates the installation, replacement, and subsequent maintenance of the combustion sound module 2, resulting in higher assembly efficiency and improved production and after-sales efficiency, meeting users' requirements for "realism" and "smooth interaction" in smart home applications.

[0037] In this embodiment, the mounting base 11 is integrally set with the body. The mounting base 11 is a box structure with an opening on one side. The combustion sound effect module 2 is set inside the mounting base 11. The cover 12 is sealed at the opening of the mounting base 11 and is detachably connected to the mounting base 11.

[0038] In some embodiments, such as Figures 8 to 11 ,as well as Figure 17 As shown, one end of the cover 12 is provided with a connector 121, and the mounting base 11 is provided with a corresponding slot 111 for the connector 121 to be inserted.

[0039] In the above embodiment, a connector 121 is provided at one end of the cover 12, and a corresponding slot 111 is provided on the mounting base 11. During assembly, the end of the cover 12 with the connector 121 is first inserted obliquely into the slot 111, and then the other end of the cover 12 is pressed into the mounting base 11 for locking and fixing. The cooperation between the connector 121 and the slot 111 achieves rapid pre-positioning in the initial stage of installation, prevents misalignment, and improves assembly accuracy and efficiency.

[0040] Specifically, the cover 12 is square or rectangular, and the mounting base 11 is correspondingly set as a square or rectangular box. The mounting base 11 includes a first sidewall and a second sidewall arranged opposite each other. The first sidewall is provided with a slot 111, and the second sidewall is provided with a snap-fit ​​structure that engages with the cover 12. The insertion rib 121 is fixedly set on the sidewall of the cover 12 near the mounting cavity and is an L-shaped rib. The insertion rib 121 includes an insertion section and a connecting section connected in an L-shape. The insertion section is inserted into the slot 111, and the connecting section connects the insertion section and the cover 12. The L-shaped design of the insertion rib 121 provides better anti-detachment effect.

[0041] In some embodiments, the snap-fit ​​structure includes a snap-fit ​​122 fixedly disposed at the other end of the cover 12 and a snap-fit ​​platform 112 correspondingly disposed on the mounting base 11; the snap-fit ​​122 and / or the snap-fit ​​platform 112 are provided with guide slopes for guiding the snap-fit ​​122 to snap onto the snap-fit ​​platform 112.

[0042] In the above embodiments, the design of the guide slope makes the fastening process of the buckle 122 and the locking platform 112 smoother, avoids structural damage caused by mechanical jamming, and improves the assembly experience.

[0043] Specifically, the latch 112 is fixedly mounted on the second side wall of the mounting base 11. The side wall of the latch 112 near the opening of the mounting base 11 is inclined to form a guide slope, and the side wall of the latch 112 away from the opening of the mounting base 11 is a snap-fit ​​wall, which is a straight wall surface perpendicular to the second side wall. The latch 122 includes a main body and a snap-fit ​​part. The main body is connected between the cover 12 and the snap-fit ​​part. The snap-fit ​​part is fixedly mounted at the end of the main body, and the end of the snap-fit ​​part is chamfered to form a guide slope. The two guide slopes cooperate with each other to guide the latch 122 to snap more smoothly into the latch 112.

[0044] In some embodiments, the latches 122 are two spaced apart, and the mounting base 11 is provided with two corresponding latching platforms 112. The two latches 122 and the two latching platforms 112 are engaged in a one-to-one manner. The spaced-apart latches 122 further improve the stability of the cover 12.

[0045] In some embodiments, the cover 12 is provided with a plurality of sound holes.

[0046] In some embodiments, the cover 12 is provided with a first support rib 123 for abutting and engaging with the combustion sound effect module 2.

[0047] In the above embodiment, by providing a first support rib 123 on the cover 12, the first support rib 123 abuts against the first support rib 123, effectively limiting the vibration displacement of the speaker during operation, preventing resonance noise with the surrounding structure, ensuring the purity of the flame sound effect, and improving the sound pickup accuracy.

[0048] Specifically, the first support rib 123 is fixedly disposed on the side of the cover 12 near the mounting cavity, and the first support rib 123 is located at the center of the cover 12. By placing the first support rib 123 at the center of the cover 12, it is equivalent to providing direct support at the core of the speaker's vibration mass, that is, near the center of the combustion sound effect module 2. This allows the vibration energy from the drive motor 132 and the combustion sound effect module 2 itself to be transmitted to the cover 12 and the entire motor bracket 133 with the shortest path and the smallest lever arm, and absorbed and dissipated by the rigid structure. This can minimize unnecessary vibration, avoid generating noise, and thus ensure that the played flame sound effect is purer and more realistic. In addition, when the cover 12 is locked by snap-fit, the central support rib can evenly bear the locking force from all sides and evenly transmit the pressure back to the speaker housing. This can prevent the housing of the combustion sound effect module 2 from slight deformation that may occur due to force on one side or edge. Such deformation can sometimes affect the accuracy of the internal magnetic circuit and air gap of the combustion sound effect module 2, thereby affecting the sound quality. At the same time, the even force distribution also protects the housing of the combustion sound effect module 2.

[0049] In some embodiments, the mounting base 11 also has a positioning rib 113 that matches the outer periphery of the combustion sound effect module 2.

[0050] In the above embodiment, by matching the contour of the positioning rib 113 with the combustion sound effect module 2, the vibration displacement of the combustion sound effect module 2 during operation is effectively limited, preventing resonance noise with the surrounding structure and ensuring the purity of the flame sound effect. The positioning rib 113 can also ensure that the combustion sound effect module 2 is accurately and stably positioned in the mounting cavity, avoiding the impact of displacement on the acoustic output effect.

[0051] Based on the above embodiments, as a further defined embodiment, the positioning rib 113 can be a ring-shaped rib or the positioning rib 113 can also be designed to correspond to the corners of the combustion sound module 2. For example, if the combustion sound module 2 has a square cross-section, the positioning rib 113 can be set to four, which are distributed at the four corners of the combustion sound module 2. The positioning rib 113 is in the shape of a "┐".

[0052] In some embodiments, the main body 1 of the heater includes a fan assembly 13, the fan assembly 13 includes a fan blade 131, a drive motor 132 for driving the fan blade 131 to rotate, and a motor bracket 133 for mounting the drive motor 132; a first recess is integrally formed on the motor bracket 133, the first recess forming a mounting base 11.

[0053] In the above embodiment, by cleverly utilizing the physical structure of the motor bracket 133, without adding extra components or occupying space, the first recess integrally formed on the motor bracket 133 provides a space for the combustion sound effect module 2, thereby achieving a compact structure and functional integration, and improving space utilization.

[0054] In some embodiments, the combustion sound module 2 is connected to the main board 18 of the flame heater via a lead wire 21. The first recess is provided with a wiring hole 114 for the lead wire 21 to pass through. A wiring structure is also formed on the motor bracket 133, which is used to constrain the direction of the lead wire 21.

[0055] In the above embodiments, the design of the wiring hole 114 and the wiring structure can organize the lead wire 21, prevent it from scattering inside the equipment, avoid interference with moving parts (such as the fan blade 131), simplify wiring, and improve safety and reliability.

[0056] In some embodiments, the motor bracket 133 includes a bracket body and an annular rib 1331 fixedly disposed on the bracket body. The annular rib 1331 is located on the outer periphery of the bracket body and forms a reserved gap with the outer periphery edge of the bracket body. The wiring structure includes a notch 1332 formed in the annular rib 1331, through which the lead wire 21 passes to the reserved gap. The wiring structure also includes a wire buckle 1333 fixedly disposed on the bracket body and located on the outer periphery of the annular rib 1331. The wire buckle 1333, the annular rib 1331, and the bracket body enclose a wiring channel. A gap opening is provided between the wire buckle 1333 and the annular rib for the lead wire 21 to be inserted into the wiring channel. The wiring structure also includes a baffle 1334 fixedly disposed on the outer wall of the annular rib 1331 and offset from the wire buckle 1333 to prevent the lead wire 21 from coming out of the gap opening.

[0057] In the above embodiment, the wiring structure, by adopting the design of notch 1332, wire clip 1333, and baffle 1334, provides a clear and optimized wiring path for the lead wire 21 of the combustion sound module 2 to the motherboard 18, reduces signal interference, ensures the consistency of cable layout in mass production, and makes the wiring path more standardized. The design of wire clip 1333 and baffle 1334 makes the lead wire 21 firmly constrained in the wiring channel. The lead wire 21 is directly connected to the motherboard 18 along the wiring channel, which simplifies wiring and avoids it from falling off due to vibration or being caught in the fan assembly 13.

[0058] Specifically, the mainboard 18 is located on one side of the motor bracket 133. An annular rib 1331 on the bracket body divides the bracket body into two parts, preventing interference between the lead wire 21 and the drive motor 132, fan blade 131, etc., between the motor bracket 133. The wire clip 1333 is L-shaped or Z-shaped, with a gap opening between the end of the L-shaped or Z-shaped wire clip 1333 and the annular rib 1331 for the lead wire 21 to be inserted. Preferably, the end of the wire clip 1333 is chamfered to form a bevel, guiding the lead wire 21 into the wiring channel. A retaining rib 1334 is located between the wire clip 1333 and the notch 1332. The length of the retaining rib 1334 is not less than the opening length of the gap opening, effectively preventing the lead wire 21 from accidentally coming out of the gap opening.

[0059] It should be noted that in this embodiment, the combustion sound effect module 2 includes a flame speaker 20. The combustion sound effect module 2 is connected to the motherboard 18, and the motherboard 18 can control the opening and closing of the combustion sound effect module 2, the volume, the type of sound played, etc.

[0060] In some embodiments, combined with Figure 6 and Figure 7 , Figure 16 , Figure 18 As shown, the flame-shaped heater also includes a voice control module, which includes a voice speaker 3; the heater body 1 also includes a rear shell assembly 141, which includes a rear shell 1411 and a rear air duct 1412 disposed inside the rear shell 1411; a second recess 14121 is integrally formed on the rear air duct 1412, and a mounting groove for mounting the voice speaker 3 is formed in the second recess 14121; the rear shell 1411 seals the opening of the mounting groove, and a second support rib 14111 is provided on the rear shell 1411 at the position corresponding to the second recess 14121 for abutting and cooperating with the voice speaker 3. Specifically, such as Figure 7 As shown, the second recess 14121 is recessed in a direction away from the rear shell 1411, as... Figure 16 As shown, the second support rib 14111 on the rear shell 1411 is cylindrical.

[0061] In the above embodiment, the voice speaker 3 is mounted on the rear air duct 1412, and the combustion sound module 2 is mounted on the motor bracket 133, achieving dual separation of the voice speaker 3 and the flame speaker 20 in terms of physical position and mounting structure. The second support rib 14111 on the rear shell 1411 provides stable support for the voice speaker 3, effectively isolating mechanical noise such as vibration of the fan assembly 13 and improving the accuracy of voice wake-up and recognition. Furthermore, without adding extra components or occupying additional space, the integrated recess of the rear air duct 1412 serves as the mounting slot for the voice speaker 3, resulting in a robust structure and space-saving design.

[0062] This embodiment provides a dual-speaker independent functional division for the heater. The voice speaker 3 is used for overall function control, including but not limited to power on / off, timer, and flame / light volume adjustment, and is integrated into the rear air duct 1412 structure. The flame speaker 20 is dedicated to simulating flame combustion sounds, playing sound only when the heater is on and entering standby mode when off. In standby mode, it assists the voice speaker 3 in volume adjustment, jointly increasing the upper volume limit and avoiding conflicts with voice interaction. The voice speaker 3 is integrated into the second recess 14121 of the rear air duct 1412. A second support rib 14111 is provided at a corresponding position on the rear shell 1411 to support the voice speaker 3, ensuring sound pickup stability. The flame speaker 20 is embedded in the first recess of the motor bracket 133 and fixed by the cover 12 to avoid vibration interference. The lead wire 21 of the flame speaker 20 is directly connected to the main board 18 via a wiring structure, simplifying wiring.

[0063] In some embodiments, the main body 1 of the heater also includes a simulated flame module, which includes a charcoal component 15 and a lighting component 16. The charcoal component 15 includes a display panel 151, simulated charcoal 152 and a light shield 153 arranged sequentially from the outside to the inside. An installation space for accommodating the simulated charcoal 152 is formed between the display panel 151 and the light shield 153. The lighting component 16 is disposed on the side near the light shield 153. The lighting component 16 includes a light-emitting element 161 and a reflector. The reflector includes a reflector 162 and a stepper motor 163 for driving the reflector 162 to rotate. The reflector 162 rotates under the drive of the stepper motor 163 to reflect the light emitted by the light-emitting element 161 onto the light shield 153, so that the simulated charcoal 152 creates a visual effect of burning.

[0064] In the above embodiments, the charcoal fire component 15 and the lighting component 16 simulate the effect of flame combustion, making it more realistic and dynamic, enhancing the realism and atmosphere of the visual effect. Furthermore, the charcoal fire component 15 uses a combination of simulated charcoal 152, a display panel 151, and a light-shielding sheet 153 to form a "combustion chamber" structure with depth, enhancing the layering and three-dimensionality of the flame. The lighting component 16 uses a stepper motor 163 and a reflector 162. The stepper motor 163 drives the reflector 162 to rotate continuously, dynamically reflecting the light emitted by the light-emitting element 161 to the light-shielding sheet 153. This makes the simulated charcoal 152 exhibit a flickering, dimming visual effect, highly simulating the dynamic light of a real flame, creating a warm, comfortable, and realistic flame atmosphere. This provides an immersive user experience, adding a simulated flame visual scene to the heating function, making it more competitive in the market. In addition, the reflective elements prevent the light source from shining directly into the eyes. Instead, the light is reflected and softened twice by the reflector 162 and the light shield 153, resulting in more uniform and softer light, reducing visual stimulation and making it suitable for long-term viewing.

[0065] Specifically, the display panel 151 is located on the front side of the entire machine. The display panel 151 and the light shield 153 are arranged opposite each other, and the two enclose a combustion chamber for accommodating and installing the simulated charcoal 152. The light-emitting element 161 is located at the bottom of the housing 14. Preferably, the light-emitting element 161 is a light-emitting plate. The reflector is located above the light-emitting element 161 and corresponds to the light shield 153. There are multiple light-emitting plates, which are spaced apart in the horizontal direction. The multiple reflectors 162 are connected by a relatively long drive shaft. The stepper motor 163 is connected to the drive shaft. By driving the drive shaft to rotate, the multiple reflectors 162 are rotated. The stepper motor 163 is mounted on the motor bracket 133. Preferably, the annular rib 1331 of the motor bracket 133 is recessed towards the center to form a mounting part. The stepper motor 163 is mounted in this mounting part and is located on the outer periphery of the annular rib 1331. The mounting part has an opening for the drive shaft to pass into the annular rib 1331.

[0066] In some embodiments, the main body 1 of the heater also includes a housing 14 and a heating element assembly 17. The housing 14 includes an annular outer shell 142, a front mesh cover assembly 143 and a rear shell assembly 141 installed at both ends of the annular outer shell 142. The front mesh cover assembly 143 is annular. A charcoal fire assembly 15 is installed in the middle area of ​​the front mesh cover assembly 143. A light assembly 16 is disposed in the cavity formed between the annular outer shell 142 and the rear shell assembly 141. The front mesh cover assembly 143 includes an annular front mesh cover 1431, which has a plurality of air outlets 1430. The heating element assembly 17 is annular and is disposed inside the housing 14 near the air outlets 1430 for heating the airflow at the air outlets 1430.

[0067] In the above embodiment: by matching the annular heating element assembly 17 with the annular air outlet 1430, the airflow is uniformly heated as it passes through, forming an annular hot air band, expanding the heating range, and increasing the indoor temperature more quickly and evenly. Furthermore, by integrating the front grille 1431 and rear shell 1411 with the annular outer shell 142, the internal components are arranged in an annular layout, maximizing space utilization, resulting in a compact overall structure that facilitates installation and placement. Moreover, the design of the front grille 1431 not only forms the annular air outlet 1430 but also effectively isolates the user from the heating element, preventing accidental contact and reducing the risk of burns. Air enters through the air inlet 1410 on the rear shell 1411, flows through the annular heating element for thorough heating, and is then concentrated and blown out from the annular air outlet 1430, ensuring a smooth path, high heat exchange efficiency, and reduced energy loss. In addition, the annular front grille 1431, combined with the charcoal fire assembly 15, resembles a modern fireplace in appearance, with an elegant design that meets consumers' aesthetic needs for home appliance aesthetics and is suitable for various home styles.

[0068] In this embodiment, the main body 1 of the heater is disc-shaped, similar to a fan head. Control modules such as the main board 18 are mounted on the top of the main body 1. Specifically, a mounting position for the main board 18 is formed above the motor bracket 133. The voice control module also includes a voice microphone 4, which is mounted on the annular housing 142. Preferably, the voice microphone 4 is also mounted on the top of the annular housing 142 for easy connection to the main board 18 on the top. The front grille assembly 143 includes a grille bracket 1432, and the front grille 1431 is mounted on the annular housing 142 via the grille bracket 1432.

[0069] In some embodiments, the light-shielding sheet 153 corresponds to the upper half of the display panel 151, and the simulated charcoal 152 corresponds to the lower half of the display panel 151. The projections of the light-shielding sheet 153 and the simulated charcoal 152 onto the display panel 151 overlap, and the simulated charcoal 152 is sandwiched between the display panel 151 and the light-shielding sheet 153. This design allows a flame-burning effect to be created above the simulated charcoal 152 when illuminated by the light assembly 16, while also saving material on the light-shielding sheet 153.

[0070] In some embodiments, the heater further includes a support frame for supporting the heater body 1 at a set height above the ground. The support frame is detachably connected to the heater body 1 for easy storage, packaging, and transportation. Optionally, the support frame is threadedly connected to the heater body 1. The support frame includes multiple support columns, and multiple adapter pipes 14112 are fixedly installed on the rear shell 1411 of the heater body 1. The multiple support columns and the multiple adapter pipes 14112 are threadedly connected one-to-one.

[0071] This embodiment provides a flame-shaped fan heater with a dual-speaker system and annular air outlet, comprising a housing 14, a heating module, a simulated flame module, a voice control module, and a combustion sound effect module 2. The specific functions of each module are as follows: The fan heater uses an annular heating element, which is fixed on an annular mesh support 1432. The air generated by the fan blades 131 rotating, driven by a motor 132, first passes through a rear air duct 1412 and then is blown out from the annular air outlet 1430 of the front mesh 1431 to achieve a uniform heating effect. The simulated flame module mainly includes simulated charcoal 152, a light-emitting component 161, a light-shielding component, and a reflector. The simulated charcoal 152 is a highly translucent component that turns red when illuminated. Under the strong light of the light-emitting component 161, the simulated charcoal 152 creates the effect of a simulated flame. The light-emitting component 161 is a light-emitting panel, with its light source located below the main body 1 of the heater, shining light upwards. The light-shielding component is a light-shielding sheet 153, similar to a curtain. The reflector includes a stepper motor 163 and multiple reflectors 162 that rotate under the drive of the stepper motor 163. Driven by the stepper motor 163, the reflectors 162 continuously rotate and reflect the light-emitting component 161 of the light panel, mapping the reflected light onto the light-shielding sheet 153 to create the smoke effect of burning charcoal. The voice control module consists of a voice speaker 3 and a voice microphone 4 (with lead wire). The voice speaker 3 is installed in the second recess 14121 of the rear air duct 1412 and is fixed by the back cover 1411. The back cover 1411 has a ring of rib structure, namely the second support rib 14111, corresponding to the position of the voice speaker 3, to support the voice speaker 3 and make it stably installed inside the rear air duct 1412, and is connected to the main board 18 through a reserved wiring channel. The combustion sound effect module 2 consists of an independent flame speaker 20. The flame speaker 20 is installed in the first recess of the motor bracket 133. The first recess has a positioning rib 113 and is covered and fixed by a cover 12. The cover 12 has a plug rib 121 and two buckles 122 to ensure stable installation and easy disassembly and maintenance. The flame speaker 20 is connected to the main board 18 through the wiring structure on the motor bracket 133 and is used to play the sound of flame combustion. The flame speaker 20 is fixed by the deep groove of the motor bracket 133 and the cover 12, and the microphone is supported by the first support rib 123 on the rear air duct 1412, ensuring vibration isolation and sound pickup accuracy. This not only achieves a more realistic audio-visual effect for the flame heater, but also improves the installation stability and assembly efficiency of the flame speaker 20 while fulfilling its functionality. This application uses the flame sound speaker to independently play simulated flame combustion sounds, such as crackling and low-frequency combustion sounds, enhancing the immersive simulation. The controller manages the flame speaker 20: when it is on, it only plays sound; when it is off, it automatically enters standby auxiliary mode to avoid functional conflicts.

[0072] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the protection scope of the embodiments of this application.
