[0002] Traditional outdoor stoves typically have manually adjustable gas valves. Once the valve is set, the flame remains relatively stable and static. Furthermore, these stoves are functionally limited to heating and lack any added auditory or visual immersive effects. To meet user needs, stoves with music functionality have emerged on the market, where the flame changes with the pitch of the music, creating a dynamic effect of the flame dancing to the beat.

[0003] For example, a stove disclosed in Chinese Utility Model Patent (Authorization Announcement No.: CN223121468U) includes a stove body and a flame generator disposed on the stove body. An audio device is provided on the stove body, and an accommodating space is provided above the audio device. The flame generator is disposed in the accommodating space and has a flame generating chamber inside. The lower end of the flame generator has a mounting hole that corresponds to and cooperates with the audio device. An elastic membrane is disposed in the mounting hole. The audio sound waves played by the audio device cause the flame generated above the flame generator to change dynamically through the elastic membrane. The stove body also serves as a sound system. The stove can not only be used as a heating device, but also play music. The flame on the top surface of the stove can change with the rise and fall of the music, forming a phenomenon of dancing with the music, bringing a dual enjoyment of sight and sound.

[0028] like Figures 1 to 10As shown, a fire-watching stove includes a stove body 1. The stove body 1 is equipped with a burner 2 and a first audio device 3. The burner 2 has a combustion chamber 21. A sound-receiving device 4 is provided above the first audio device 3. One end of the sound-receiving device 4 is connected to the combustion chamber 21, and the other end of the sound-receiving device 4 is provided with an elastic diaphragm 41, which is correspondingly arranged with the first audio device 3. When the first audio device 3 plays audio, its sound waves pass through the elastic diaphragm 41, causing the flame generated above the burner 2 to dynamically change. The stove body 1 is also equipped with a second audio device 5, and the first audio device 3 and the second audio device 5 are synchronized in audio playback. The stove body 1 is provided with sound guide holes 11 on the wall surfaces corresponding to the first audio device 3 and the second audio device 5, respectively. A control board 6 is provided inside the stove body 1, and the first audio device 3 and the second audio device 5 are both electrically connected to the control board 6.

[0029] Based on the above embodiments, this utility model provides a fire-viewing stove, including a stove body 1. The stove body 1 is equipped with a burner 2 and a first audio device 3. The stove body 1 is also equipped with a second audio device 5. The first audio device 3 and the second audio device 5 are synchronized in audio playback. This utility model is equipped with a first audio device 3 and a second audio device 5. The amplifier end of the first audio device 3 corresponds to the elastic diaphragm 41 at the large opening 43 of the sound receiving device 4, and is used to cooperate with the sound receiving device 4 to realize the dynamic changes of the flame. The amplifier end of the second audio device 5 corresponds to the sound guide hole 11 on the side wall of the stove body 1, and is used to improve the user's listening effect.

[0030] The working principle is as follows: Combustible gas is supplied to the combustion chamber 21 via the gas supply pipe 81, and the flame burns above the flame nozzle 22. When the first audio device 3 plays music, the sound pressure from the first audio device 3 causes the elastic diaphragm 41 to vibrate. The combustion chamber 21 is filled with combustible gas. When the elastic diaphragm 41 vibrates upward, it squeezes out the combustible gas in the combustion chamber 21, causing the flame to increase. When the elastic diaphragm 41 rebounds, the flame remains unchanged due to the replenishment of combustible gas. In addition, the audio waves played by the first audio device 3 are transmitted to the inside of the combustion chamber 21 through the elastic diaphragm 41. When the sound waves come into contact with the inner wall of the burner 2, they are reflected back, and the reflected sound waves are superimposed on the original sound waves. Because two waves with the same amplitude and frequency and opposite propagation directions are superimposed, an interference phenomenon is formed. The position where the amplitude is zero is called a node, and the position where the amplitude is the largest is called an antinode. The nodes and antinodes cause differences in the density of combustible gas at various locations within the combustion chamber 21, resulting in denser combustible gas in some burner holes 22 and sparser gas in others, thus causing different flame heights for each burner hole 22. This causes the flame to fluctuate with the music, creating a dancing effect, showcasing a unique artistic expression through the combination of flame and music, and providing users with a novel sensory experience. Simultaneously, the furnace body 1 is also equipped with a second audio device 5, which plays audio synchronously with the first audio device 3. The amplifier end of the second audio device 5 corresponds to the sound guide hole 11 on the side wall of the furnace body 1, enhancing the user's listening experience.

[0031] It should be noted that, due to the upward movement of hot air, the flame burns above the flame hole 22. Although the temperature above the burner 2 is high, the temperature at the large opening 43 of the sound receiving device 4 can still be kept within a safe range and is not enough to damage the elastic diaphragm 41.

[0032] In this embodiment, the first audio device 3 and the second audio device 5 are specifically Bluetooth speakers, which can be connected to mobile terminals such as mobile phones and tablets via Bluetooth. Users can conveniently control music playback and volume adjustment using these mobile terminals.

[0033] In this embodiment, the sound guide hole 11 facilitates the transmission of sound waves from the first audio device 3 and the second audio device 5 to the outside world, making it easier for users to hear the audio more clearly.

[0034] In another preferred embodiment of this utility model, the furnace body 1 is provided with a battery box 7, which is electrically connected to the control board 6. In this embodiment, as... Figure 3As shown, the battery box 7 contains batteries, allowing users to flexibly choose between rechargeable or dry-cell batteries according to their needs. This structural design frees the fire-watching stove from dependence on a fixed power source, ensuring power supply, especially in scenarios without mains power, such as outdoor camping and country tea parties, significantly improving the stove's adaptability to various usage scenarios. When using rechargeable batteries, charging can be completed through the charging port on the side wall of the stove body 1, reducing the tedious operation of frequent battery replacements, lowering long-term consumable costs, and further demonstrating a green and environmentally friendly design concept by reducing the environmental pollution caused by discarded dry-cell batteries. If dry-cell batteries are chosen, they can be quickly replaced in emergency situations where charging is unavailable, ensuring continuous operation of the device. The flexible switching between the two power supply modes further enhances the convenience and reliability of the fire-watching stove.

[0035] In another preferred embodiment of this utility model, the control panel 6 is equipped with a display screen 61. The side wall of the furnace body 1 is provided with a plurality of through holes 12, and the positions of the plurality of through holes 12 correspond to those of the display screen 61. In this embodiment, as... Figure 3 As shown, the remaining battery power in the battery box 7 can be clearly viewed through the display screen 61, facilitating timely charging. During charging, the user can also observe whether the battery is fully charged through the display screen 61. The side wall of the furnace body 1 is provided with several through holes 12 corresponding to the positions of the display screen 61, allowing the user to observe the remaining battery power displayed on the display screen 61 through these through holes 12.

[0036] In another preferred embodiment of this utility model, one end of the sound-receiving device 4 is a small-aperture end 42, and the other end is a large-aperture end 43. The sound-receiving device 4 is connected to the burner 2 through the small-aperture end 42, and the elastic diaphragm 41 is disposed at the large-aperture end 43. In this embodiment, as... Figure 4 and Figure 5 As shown, the sound receiving device 4 is designed in a funnel shape, with an elastic diaphragm 41 at its large end 43. When the first audio device 3 generates sound waves, the air pressure inside the sound receiving device 4 fluctuates due to the vibration of the elastic diaphragm 41 at the large end 43. This air pressure fluctuation is then transmitted to the combustion chamber 21 through the small end 42, which can enhance the dynamic change effect of the flame above the burner 2.

[0037] As another preferred embodiment of this utility model, the first audio device 3 is mounted to the bottom of the furnace body 1 via a first mounting bracket 31, and the second audio device 5 is mounted to the side wall of the furnace body 1 via a second mounting bracket 51. In this embodiment, as... Figure 3 and Figure 6 As shown, the first audio device 3 and the second audio device 5 are fixedly installed by the first mounting bracket 31 and the second mounting bracket 51 respectively, and the installation is reliable and the disassembly is convenient.

[0038] In another preferred embodiment of this utility model, a partition 13 is provided inside the furnace body 1, dividing the interior of the furnace body 1 into a first chamber 14 and a second chamber 15. The burner 2 is located in the first chamber 14, and the first audio device 3 and the second audio device 5 are both located in the second chamber 15. A gas source 8 and a gas supply pipe 81 are also provided in the second chamber 15. One end of the gas supply pipe 81 is connected to the gas source 8, and the other end is connected to the combustion chamber 21 of the burner 2. The burner 2 is provided with a plurality of flame holes 22 communicating with the combustion chamber 21. A combustion hood 9 is also provided in the first chamber 14. The combustion hood 9 is provided with flame outlets 91 corresponding to the flame holes 22, extending along the length of the combustion hood 9. A flame distribution net 92 is provided at each flame outlet 91.

[0039] In this embodiment, as Figure 4 As shown, the partition 13 divides the furnace body 1 into a first chamber 14 and a second chamber 15. The first chamber 14 is the combustion chamber, where the burner 2 is located. The two side walls of the furnace body 1 corresponding to the combustion chamber are observation windows 16, which are made of high-temperature resistant glass. The observation windows 16 allow for convenient observation of the flame. With observation windows 16 on both sides, users can observe the flame from two directions, ensuring a clear view of the flame and expanding the viewing angle, thus enhancing the convenience and aesthetics of the user experience. In a further preferred embodiment, the partition 13 has a mounting groove 131, in which the burner 2 is installed. The peripheral wall of the partition 13 extends downwards and / or downwards with an "L"-shaped bend 132, and the side wall of the furnace body 1 is fixedly connected to the bend 132 by bolts. The partition 13 is fixedly connected to the side wall of the furnace body 1 through the bent portion 132 of its peripheral wall. This connection structure is simple and reliable.

[0040] In this embodiment, a combustion hood 9 and a fire-dispersing net 92 are also provided in the first chamber 14. This structural design effectively changes the flame shape of the burner 2, making it no longer a cluster of independently distributed flames, but rather a uniformly dispersed state. This shape is closer to the flames naturally formed when firewood is burning, enhancing the realism during use and improving the aesthetics of the fire-viewing stove. In a further preferred embodiment, the combustion hood 9 is provided with an inwardly bent edge 93, and the partition 13 is fixedly connected to the bent edge 93 by screws. The bent edge 93 increases the firmness and stability of the connection between the combustion hood 9 and the partition 13, while also facilitating disassembly and installation, improving the practicality and maintenance convenience of the overall structure.

[0041] In this embodiment, the gas source 8, control board 6, first audio device 3 and second audio device 5 are all located in the second chamber 15, and the side wall of the furnace body 1 corresponding to the second chamber 15 is provided with a sliding door 18. The sliding door 18 can be opened relative to the furnace body 1 to facilitate the replacement of the gas source 8 in the gas supply chamber or the maintenance of the control board 6, first audio device 3 and second audio device 5.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
