Description

Technical Field

[0001] This application relates to the field of kitchen appliances technology, specifically a gas stove anti-wind flameout protection device. Background Technology

[0002] With the continuous advancement of modern kitchen equipment technology, the safety performance of gas stoves has been significantly improved. Among them, the flame failure device, as an important safety component of gas stoves, can quickly cut off the gas supply when the flame is accidentally extinguished, effectively preventing gas leaks and ensuring user safety.

[0003] Chinese utility model patent with authorization announcement number CN221301396U proposes a gas stove flameout protection device. This device, through the design of specific protective components, realizes the cleaning function of the outside of the UV tube assembly, solving the problem that water easily adheres to the outside of the UV tube assembly, thus affecting the UV irradiation and the normal judgment of the UV tube on the stove, and improving the practicality and reliability of the protection device.

[0004] However, despite its excellent performance in flameout protection, this device still has some shortcomings in practical applications. Specifically, while it focuses primarily on safety after the flame goes out, it fails to adequately consider the wind protection needs of the flame during combustion. During gas stove use, wind interference can cause uneven flame distribution, resulting in flames that are too concentrated in some areas and relatively weaker in others. This uneven flame distribution not only affects cooking results but can also lead to localized overheating of heated components (such as the bottom of the pot), increasing safety hazards.

[0005] Therefore, this application provides a gas stove anti-wind flameout protection device to solve the above problems. Utility Model Content

[0006] This application provides a windproof flameout protection device for gas stoves, aiming to solve the problem mentioned in the background art where wind interference during gas stove use can lead to uneven flame distribution, causing the flame to be too concentrated in some areas and relatively weak in others. This uneven flame distribution not only affects cooking results but may also cause localized overheating of heated components (such as the bottom of the pot), increasing safety hazards.

[0007] To achieve the above objectives, this application provides the following technical solution: a gas stove anti-wind flameout protection device, comprising a windproof ring, an annular air duct formed inside the windproof ring, an air inlet formed on the outer wall of the windproof ring and communicating with the annular air duct, and an air outlet formed on the inner wall of the windproof ring and communicating with the annular air duct, wherein the air outlet corresponds to the air inlet; when the gas stove is ignited, the flame begins to burn and generate heat. During this process, the flame burns oxygen in the air, thereby generating a suction force at the air outlet. This suction force causes external air to enter the annular air duct through the air inlet, and then, guided by the annular air duct, is discharged from the air outlet and comes into contact with the flame. This not only provides sufficient oxygen for the flame but also supports its continuous combustion. Simultaneously, the presence of the windproof ring effectively blocks interference from external wind forces, preventing uneven flame distribution under the influence of wind. This allows the flame to maintain a stable and uniform distribution, thereby improving the combustion efficiency and safety of the gas stove.

[0008] It also includes V-shaped plates arranged in a ring array inside the annular air duct and corresponding to the air inlet, with the open end of the V-shaped plates positioned close to the air outlet. When the gas stove is ignited, the V-shaped plates inside the annular air duct divert the incoming gas, reducing its flow velocity before it exits the air outlet and preventing direct impact on the flame.

[0009] Preferably, the two ends of the V-shaped plate are arc-shaped. The arc-shaped design of the two ends of the V-shaped plate allows the gas to be diverted more smoothly when passing through, further reducing the flow velocity of the gas flowing out of the air outlet, avoiding direct impact on the flame, and thus protecting the stable combustion of the flame.

[0010] Preferably, to facilitate the discharge of excess gas entering the annular duct, an arc-shaped plate is fixedly installed inside the annular duct between the two V-shaped plates. The curvature of the arc-shaped plate matches the curvature of the outer wall of the V-shaped plate, and the end of the arc-shaped plate corresponds to the end of the V-shaped plate. The arc-shaped plate further optimizes the gas flow path, ensuring the smooth discharge of excess gas.

[0011] Preferably, to facilitate the guiding flow of gas entering the annular duct from the air inlet: arc-shaped air guide plates are fixedly connected to both sides of the port corresponding to the air inlet inside the annular duct, and the curvature of the arc-shaped air guide plates is consistent with the curvature of the V-shaped plate. The arc-shaped air guide plates allow the gas entering from the air inlet to flow more smoothly, avoiding turbulent flow of gas inside the annular duct, and further improving the efficiency and stability of gas flow.

[0012] Preferably, to facilitate adjustment of the amount of gas flowing out of the air outlet: the windproof ring is provided with an airflow adjustment structure for adjusting the amount of gas flowing out of the air outlet. The airflow adjustment structure includes ventilation holes formed on the V-shaped plate, a mesh adjustment plate disposed inside the ventilation holes, a screw rotatably inserted into the windproof ring and fixedly connected to the upper end of the mesh adjustment plate, and a threaded sleeve threaded onto the screw. Through the airflow adjustment structure, the user can precisely adjust the amount of gas flowing out of the air outlet according to actual needs, thereby achieving precise control of the flame combustion state. By adjusting the ventilation volume, it is ensured that the flame receives adequate oxygen support, improving combustion efficiency and reducing energy waste.

[0013] Preferably, to enable the synchronous raising and lowering of multiple mesh adjustment plates: a synchronization mechanism is provided inside the windproof ring for driving the synchronous rotation of multiple screw sleeves. The synchronization mechanism includes an internal gear ring rotatably disposed inside the windproof ring, an annular internal gear groove formed on the screw sleeve and meshing with the internal gear ring, a worm gear fitted onto one of the screws and fixedly connected to the screw sleeve on that screw, and a worm inserted into the windproof ring and meshing with the worm gear. Through the synchronization mechanism, the synchronous raising and lowering of multiple mesh adjustment plates is achieved, avoiding the problem of uneven ventilation caused by inconsistent raising and lowering of individual mesh adjustment plates.

[0014] This application effectively blocks external wind interference through the design of a windproof ring and annular air duct, ensuring a stable and even flame distribution. The coordinated use of the air inlet and outlet provides ample oxygen to the flame, supporting continuous combustion and thus improving the gas stove's combustion efficiency. When the flame extinguishes, the windproof ring slows down the extinguishing process, providing a longer response time for the flameout protection device and enhancing the gas stove's safety. The device has a simple structure, is easy to install and disassemble, and facilitates daily maintenance and cleaning for users.

[0015] The V-shaped plate in this application diverts the gas entering the annular air duct, reducing the gas flow velocity from the outlet and avoiding direct impact of the gas on the flame, thereby protecting the stable combustion of the flame.

[0016] This application, through its airflow regulation structure, allows users to precisely adjust the amount of gas flowing from the air outlet according to actual needs, thereby achieving precise control over the flame combustion state. By adjusting the ventilation volume, it ensures that the flame receives adequate oxygen support, improving combustion efficiency and reducing energy waste.

[0017] This application achieves synchronized lifting and lowering of multiple mesh adjustment plates through the setting of a synchronization mechanism, avoiding the problem of uneven ventilation caused by inconsistent lifting and lowering of individual mesh adjustment plates.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0026] Example 1

[0027] This embodiment provides a gas stove flameout protection device against wind, such as Figure 1-5As shown, the protective device includes a windproof ring 1, an annular air duct 2 inside the windproof ring 1, an air inlet 3 on the outer wall of the windproof ring 1 and connected to the annular air duct 2, and an air outlet 4 on the inner wall of the windproof ring 1 and connected to the annular air duct 2. The air outlet 4 is correspondingly located to the air inlet 3. The design of the windproof ring 1 and the annular air duct 2 effectively blocks external wind interference, allowing the flame to remain stable and evenly distributed. The cooperation of the air inlet 3 and the air outlet 4 provides sufficient oxygen to the flame, supporting its continuous combustion and thus improving the combustion efficiency of the gas stove. When the flame goes out, the windproof ring 1 slows down the flame's extinguishing speed, providing a longer response time for the flameout protection device, thereby enhancing the safety of the gas stove. The device has a simple structure, is easy to install and disassemble, and facilitates daily maintenance and cleaning for users. When the gas stove is ignited, the flame begins to burn and generate heat. During this process, the flame burns oxygen in the air, creating a suction force at the air outlet 4. This suction force draws outside air into the annular duct 2 through the air inlet 3, and then, guided by the annular duct 2, exhausts it from the air outlet 4, bringing it into contact with the flame. This not only provides ample oxygen to the flame but also supports its continuous combustion. Simultaneously, the windproof ring 1 effectively blocks external wind interference, preventing uneven flame distribution due to wind influence. This allows the flame to remain stable and evenly distributed, thereby improving the combustion efficiency and safety of the gas stove.

[0028] It also includes V-shaped plates 5 arranged in a ring array inside the annular air duct 2 and corresponding to the air inlet 3. The open end of the V-shaped plates 5 is positioned close to the air outlet 4. The V-shaped plates 5 divert the gas entering the annular air duct 2, reducing the gas velocity flowing out of the air outlet 4 and preventing the gas from directly impacting the flame, thereby protecting the stable combustion of the flame. When the gas stove is ignited, the V-shaped plates 5 inside the annular air duct 2 divert the incoming gas, reducing the gas velocity before it flows out of the air outlet 4, thus preventing direct impact on the flame.

[0029] Specifically, the V-shaped plate 5 has arc-shaped ends. This arc-shaped design allows for smoother gas diversion as it passes through, further reducing the gas velocity exiting from the outlet 4 and preventing direct impact on the flame, thus protecting the stable combustion of the flame. Inside the annular duct 2, the V-shaped plate 5, with its unique arc-shaped design, more smoothly diverts the incoming gas. The reduced gas velocity after diversion results in a gentler flow when exiting from the outlet 4, avoiding direct impact on the flame and thus protecting the stable combustion of the flame.

[0030] To facilitate the discharge of excess gas entering the annular duct 2, an arc-shaped plate 6 is fixedly installed inside the annular duct 2 between two corresponding V-shaped plates 5. The curvature of the arc-shaped plate 6 matches the curvature of the outer wall of the V-shaped plate 5, and the ends of the arc-shaped plate 6 correspond to the ends of the V-shaped plates 5. The installation of the arc-shaped plate 6 further optimizes the gas flow path, ensuring the smooth discharge of excess gas.

[0031] To facilitate the guiding flow of gas entering the annular duct 2 from the air inlet 3, curved guide plates 7 are fixedly connected to both sides of the port corresponding to the air inlet 3 inside the annular duct 2. The curvature of the curved guide plates 7 matches that of the V-shaped plate 5. The curved guide plates 7 allow the gas entering from the air inlet 3 to flow more smoothly, avoiding turbulent flow inside the annular duct 2 and further improving the efficiency and stability of gas flow. Inside the annular duct 2, the curved guide plates 7 first guide the incoming gas, ensuring that the gas can smoothly enter the diversion area of ​​the V-shaped plate 5.

[0032] Example 2

[0033] Unlike Embodiment 1, to facilitate adjustment of the amount of gas flowing out from the air outlet 4, the windproof ring 1 is equipped with an airflow adjustment structure 8 for adjusting the amount of gas flowing out from the air outlet 4. The airflow adjustment structure 8 includes a ventilation hole 81 on the V-shaped plate 5, a mesh adjustment plate 82 located inside the ventilation hole 81, a screw 83 rotatably inserted into the windproof ring 1 and fixedly connected to the upper end of the mesh adjustment plate 82, and a threaded sleeve 84 threaded onto the screw 83. Through the airflow adjustment structure 8, the user can precisely adjust the amount of gas flowing out from the air outlet 4 according to actual needs, thereby achieving precise control of the flame combustion state. By adjusting the ventilation volume, it can be ensured that the flame receives adequate oxygen support, improving combustion efficiency and reducing energy waste. After the gas stove is ignited, by adjusting the threaded sleeve 84 in the airflow adjustment structure 8, the position of the mesh adjustment plate 82 on the V-shaped plate 5 can be controlled, thereby changing the size of the ventilation hole 81 and achieving precise adjustment of the ventilation volume. When the screw sleeve 84 is rotated counterclockwise, the screw 83 causes the mesh adjustment plate 82 to move upward, increasing the opening of the ventilation hole 81 and increasing the ventilation volume; when the screw sleeve 84 is rotated clockwise, the screw 83 causes the mesh adjustment plate 82 to move downward, decreasing the opening of the ventilation hole 81 and reducing the ventilation volume.

[0034] Furthermore, to enable the synchronous raising and lowering of multiple mesh adjustment plates 82, a synchronization mechanism 9 is provided inside the windproof ring 1 to drive the synchronous rotation of multiple threaded sleeves 84. The synchronization mechanism 9 includes an internal gear ring 91 rotatably disposed inside the windproof ring 1, an annular internal gear groove 92 formed on the threaded sleeve 84 and meshing with the internal gear ring 91, a worm gear 93 fitted onto one of the screws 83 and fixedly connected to the threaded sleeve 84 on the screw 83, and a worm 94 inserted into the windproof ring 1 and meshing with the worm gear 93. Through the synchronization mechanism 9, the synchronous raising and lowering of multiple mesh adjustment plates 82 is achieved, avoiding the problem of uneven ventilation caused by inconsistent raising and lowering of individual mesh adjustment plates 82. If ventilation needs to be adjusted, the user can drive the synchronization mechanism 9 by rotating the worm 94. The rotation of the worm 94 will drive the worm gear 93 meshing with it to rotate, and the rotation of the worm gear 93 will drive the threaded sleeve 84 fixedly connected to it to rotate. Because the threaded sleeve 84 has an annular internal toothed groove 92 that meshes with the internal toothed ring 91, the rotation of the threaded sleeve 84 will drive the internal toothed ring 91 to rotate. The rotation of the internal toothed ring 91 will then drive the other threaded sleeves 84 to rotate synchronously, thereby realizing the synchronous lifting and lowering of multiple mesh adjustment plates 82.

[0035] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
