[0002] When carrying out outdoor camping activities, many camping enthusiasts like to bring various audio devices, such as portable speakers, so as to enjoy the happiness and relaxation brought by music in the embrace of nature. At the same time, in order to meet the needs of cooking and heating, they will also carry a stove. However, these devices are often large in size, making it inconvenient to carry. In addition, although traditional stoves can provide necessary heat and cooking functions, their flames usually lack attraction and are not beautiful enough to add visual pleasure to the camping experience. Moreover, the functions of the stove are relatively single, only limited to heating and cooking, and cannot meet the diverse needs of campers in terms of entertainment and life. Therefore, it is necessary to make improvements. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a stove aiming at the defects and deficiencies of the prior art, which has a simple and reasonable structure and is convenient to operate. The stove can play music while heating, and the flames on the stove will fluctuate with the music rhythm, creating a double enjoyment of vision and hearing.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A stove according to the utility model includes a stove body and a flame generator provided on the stove body. An audio device is provided on the stove body. A receiving space is provided at the upper end of the stove body for the audio device. The flame generator is provided in the receiving space. A flame generating cavity is provided in the flame generator. An installation hole corresponding to the audio device is provided at the lower end of the flame generator. An elastic membrane is provided in the installation hole. The audio sound waves played by the audio device cause the flames generated above the flame generator to change dynamically through the elastic membrane.

[0006] Further, a membrane fixing ring is fixedly provided in the installation hole. The upper end of the membrane fixing ring is communicated with the flame generating cavity, and the elastic membrane is fixedly provided at the lower end of the membrane fixing ring.

[0007] Further, a volume adjustment knob electrically connected to the audio device is provided on the side wall of the stove body.

[0008] Further, an extension plate extends upward from the peripheral wall at the upper end of the stove body. A first installation step is provided on the inner wall of the extension plate. The flame generator is provided on the first installation step. The space formed between the upper end of the first installation step and the extension plate is the receiving space.

[0009] Further, a gap is formed between the extension plate and the flame generator, and a baffle is arranged in the gap.

[0010] Further, a second installation step is arranged in the gap, and the baffle is arranged on the second installation step.

[0011] Further, a plurality of through holes are formed in the extension plate, and the through holes are arranged below the first installation step.

[0012] Further, an air duct is arranged at the lower end of the flame generator. The lower end of the air duct is connected to combustible gas, and the upper end of the air duct is communicated with the flame generation chamber.

[0013] Further, the flame generator includes a top plate and a lower cover plate. A bent portion in an "L" shape extends downward from the peripheral wall of the top plate. The lower cover plate is fixedly connected to the bent portion by screws. A closed chamber is formed by the cooperation of the top plate, the bent portion and the lower cover plate, and the chamber is the flame generation chamber.

[0014] Further, a plurality of combustion holes communicated with the flame generation chamber are evenly distributed at intervals on the top plate.

[0015] The beneficial effect of the present utility model is as follows: For a stove of the present utility model, an audio device is arranged on the stove body, and the stove body also serves as a speaker, so that the stove can not only be used as a heating device but also play music, having dual functions.

[0016] Combustible gas is input into the flame generation chamber through the air duct and ignited. The flame burns above the combustion holes. When the speaker plays music, the sound pressure of the speaker causes the elastic membrane to vibrate through the elastic membrane. The flame generation chamber is filled with combustible gas. When the elastic membrane vibrates upward, the combustible gas in the flame generation chamber will be squeezed out, and the flame will increase. When it rebounds, because of the replenishment of combustible gas, the flame remains unchanged. Therefore, the flame will jump with the music. In addition, the audio sound wave is transmitted to the inside of the flame generation chamber through the elastic membrane. When the sound wave hits the inner wall of the flame generator, the sound wave is reflected back by the inner wall, and the reflected sound wave will be superimposed on the original sound wave. Since two waves with the same amplitude, frequency, and vibration direction but opposite propagation directions are superimposed, an interference phenomenon is formed. The place where the amplitude is zero is called a wave node, and the place where the amplitude is the largest is called a wave belly. The wave nodes and wave bellies cause the density of combustible gas at each position in the flame generation chamber to be different. Some combustion holes have dense combustible gas, and some combustion holes have sparse combustible gas, so that the flame height of each combustion hole is different, and the flame on the top surface of the stove will change with the rise and fall of the music, forming a phenomenon of dancing with the music, bringing a dual enjoyment of vision and hearing.

[0027] As Figure 1 - Figure 8 shown, a kind of stove includes a furnace body 1 and a flame generator 2 provided on the furnace body 1. An audio device 3 is provided on the furnace body 1. Preferably, in this embodiment, the furnace body 1 also serves as a speaker. In order to better transmit sound, horn mesh covers 11 are provided on the front wall and the rear wall of the furnace body 1. The stove can not only be used as a heating device but also play music, having dual functions. A receiving space is provided above the audio device 3 on the furnace body 1, and the flame generator 2 is provided in the receiving space. Preferably, in this embodiment, referring to Figure 8, an extension plate 12 extends upward from the upper peripheral wall of the furnace body 1. A first installation step 121 is provided on the inner wall of the extension plate 12. The flame generator 2 is arranged on the first installation step 121 to ensure that the flame generator 2 can work stably. The space formed between the upper end of the first installation step 121 and the extension plate 12 is the accommodation space. Preferably, in this embodiment, a plurality of through holes 122 are formed in the extension plate 12. The through holes 122 are arranged below the first installation step 121, which helps air circulation and can also play a role in heat dissipation. A flame generation chamber 21 is provided inside the flame generator 2. An installation hole 2121 corresponding to and cooperating with the audio device 3 is provided at the lower end of the flame generator 2. A membrane fixing ring 22 is fixedly arranged in the installation hole 2121. The upper end of the membrane fixing ring 22 communicates with the flame generation chamber 21. An elastic membrane 221 is provided at the lower end of the membrane fixing ring 22. By providing the membrane fixing ring 22, the elastic membrane 221 can be closer to the audio device. Specifically, the elastic membrane 221 is clamped on the membrane fixing ring 22 by a clamp. The elastic membrane 221 is located above the audio device 3. When the audio device 3 plays audio, the generated sound waves will be transmitted into the flame generation chamber 21 through the elastic membrane 221 and cause dynamic changes in the flame generated above the flame generator 2. Preferably, in this embodiment, an installation groove 13 is provided in the middle of the upper end of the furnace body 1. The audio device 3 is arranged in the installation groove 13. A volume adjustment knob 4 electrically connected to the audio device 3 is provided on the side wall of the furnace body 1 for adjusting the volume. Specifically, the audio device 3 is a speaker.

[0028] Preferably, in this embodiment, referring to Figure 5 , the flame generator 2 includes a top plate 211 and a lower cover plate 212. Referring to Figure 6 , a bent portion 2111 in an "L" shape extends downward from the peripheral wall of the top plate 211. The lower cover plate 212 is fixedly connected to the bent portion 2111 by screws, and the connection relationship is stable. Specifically, a plurality of lower connection holes 2122 are provided on the lower cover plate 212. A plurality of upper connection holes 21111 corresponding to the lower connection holes 2122 are provided on the bent portion 2111. The screws pass through the lower connection holes 2122 and are connected into the upper connection holes 21111 to fix the two. A closed chamber is formed by the cooperation of the top plate 211, the bent portion 2111 and the lower cover plate 212. The chamber is the flame generation chamber 21. Specifically, the membrane fixing ring 22 is fixedly connected to the lower cover plate 212 by screws, and the connection relationship is stable. The installation hole 2121 is provided on the lower cover plate 212. It should be noted that the lower cover plate 212 is a non-metal plate with a relatively large thermal resistance. The hot air moves upward, and the flame burns above the combustion hole 2112. Although the temperature above the flame generator 2 is relatively high, the temperature at the position of the membrane fixing ring 22 can still be kept within a safe range and is not sufficient to damage the elastic membrane 221 itself.

[0029] Preferably, in this embodiment, an air duct 23 is provided at the lower end of the flame generator 2. The lower end of the air duct 23 is connected to a combustible gas, and the upper end of the air duct 23 communicates with the flame generation chamber 21.

[0030] Preferably, in this embodiment, refer to Figure 2 - Figure 3 , a plurality of combustion holes 2112 communicating with the flame generation chamber 21 are evenly distributed at intervals on the top plate 211. The combustible gas is input from the air duct 23 at the lower part of the flame generator 2 into the flame generation chamber 21, and these combustible gases form flames on the top plate 211 through the combustion holes 2112.

[0031] The working principle of the present utility model is as follows: The combustible gas is input into the flame generation chamber 21 through the air duct 23, and the flame burns above the combustion holes 2112. When the audio plays music, the sound pressure of the speaker causes the vibration of the elastic membrane 221. The flame generation chamber 21 is filled with combustible gas. When the elastic membrane 221 vibrates upward, it will squeeze out the combustible gas in the flame generation chamber 21, and the flame will increase. When it rebounds, because of the replenishment of the combustible gas, the flame remains unchanged. In addition, the played audio sound wave is transmitted to the inside of the flame generation chamber 21 through the elastic membrane 221. When the sound wave hits the inner wall of the flame generator 2, the sound wave is reflected back by the inner wall, and the reflected sound wave will be superimposed on the original sound wave. Since two waves with the same amplitude, frequency, and vibration direction but opposite propagation directions are superimposed, an interference phenomenon is formed. The place where the amplitude is zero is called a node, and the place where the amplitude is the largest is called an antinode. The nodes and antinodes cause the density of the combustible gas at each position in the flame generation chamber 21 to be different. Some combustion holes 2112 have dense combustible gas, and some combustion holes 2112 have sparse combustible gas, so that the flame heights of each combustion hole 2112 are different, and the flames on the top surface of the stove will change with the rise and fall of the music, forming a phenomenon of dancing with the music, bringing a double enjoyment of vision and hearing.

[0032] Preferably, support legs 6 extend downward around the lower end of the furnace body 1 to play a supporting role. When the furnace body 1 is placed on a table, the support legs 6 can prevent the furnace body 1 from directly contacting the table and avoid damaging the table due to high temperature.

[0033] Preferably, in this embodiment, refer to Figure 7, a gap 5 is formed between the extension plate 12 and the flame generator 2. A baffle 51 is provided in the gap 5. In order to better fix and install the baffle 51, a second installation step 52 is provided in the gap 5, and the baffle 51 is arranged on the second installation step 52. Specifically, the baffle 51 is made of heat-resistant glass material, which plays a role in wind prevention and preventing personnel from being scalded. During storage, the glass baffle 51 can be taken out to reduce the storage volume and facilitate carrying and storage. Preferably, in this embodiment, there are four baffle plates 51, which are respectively arranged around the flame generator 2, and can better play the role of wind prevention and ensure that the flame generator 2 can maintain a stable combustion state.

[0034] The above is only the preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made according to the structure, features and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
