Description

Technical Field

[0001] This utility model relates to the field of gas equipment technology, specifically to an automatic gas ignition regulating device. Background Technology

[0002] With the fast pace of modern life, people have increasingly higher demands for safety and convenience in cooking. Traditional gas appliances require users to constantly monitor the flame; forgetting to turn it off or allowing it to dry-burn can easily cause a household fire, posing a significant safety hazard. Furthermore, it's difficult to precisely control cooking time, which can easily lead to cooking errors.

[0003] Currently, although some automatic gas control products have appeared on the market, they still have shortcomings in terms of functional integration, ease of operation, and rational structural design. Some products lack an intuitive display interface, making it impossible for users to obtain relevant information in a timely manner; some products have low control precision, failing to meet diverse cooking needs; and some products have complex structures and high costs, hindering widespread adoption. Therefore, developing a safe, convenient, intelligent, and cost-effective automatic gas ignition control device is of significant practical importance.

[0004] Based on this, the present invention designs an automatic gas ignition regulating device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic gas ignition control device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic gas flame control device, comprising an intelligent flame-off control module, an intuitive display module, a transmission structure module, and a housing protection module, wherein the intelligent flame-off control module, the intuitive display module, and the transmission structure module are all fixedly installed inside the housing protection module;

[0007] The intelligent flameout control module has a built-in microcontroller that can set the automatic flameout time according to various cooking needs and can make fine adjustments to the time. When the timing cycle is completed, the system automatically executes the flameout program to turn off the stove.

[0008] The intuitive display module is equipped with an intuitive display interface that can display the remaining time in real time.

[0009] The transmission structure module uses a motor to drive a gear set, which includes a main gear, a pinion, a driven wheel, and a central shaft. The motor drives the pinion, which in turn drives the main gear. The main gear and the driven wheel rotate synchronously. The central shaft connects the stove's rotating shaft and the original rotary button, achieving rotation control under the drive of the main shaft.

[0010] The outer shell protection module: The outer shell adopts a double-layer design, and an air insulation layer is formed between the two layers, which can effectively prevent the inner layer from deforming due to high temperature and provide heat insulation protection.

[0011] In a further embodiment, the microcontroller used is an STM32F103ZET6.

[0012] In a further embodiment, the double-layer design of the outer shell includes a bottom cover and an upper cover. The motor compartment is located inside the bottom cover, and a small gear is installed inside the bottom cover and located directly below the motor compartment.

[0013] In a further embodiment, the rotating shaft of the motor is inserted into the central circular hole of the pinion.

[0014] In a further embodiment, the microcontroller is equipped with multiple buttons, each corresponding to a different time setting input.

[0015] In a further embodiment, an active actuation point is provided on the circumferential surface of the main gear, and a corresponding passive actuation point is provided on the driven gear. When the main gear rotates to the point where the active actuation point contacts the passive actuation point on the driven gear, the main gear will apply a pushing force to the driven gear, causing the driven gear to rotate.

[0016] In a further embodiment, the central shaft adopts a two-layer structure design, with the bottom layer being a hexagonal outer shell that can be inserted into the central hole of the driven wheel, thereby realizing a rotatable connection between the driven wheel and the central shaft.

It adopts a unique gear transmission structure to ensure stable operation, and combines the coordinated work of various modules of the hardware circuit.

[0018] The equipment has multiple preset standard time options and also features a button, allowing users to flexibly and precisely set the automatic shut-off time. Once the countdown ends, the system automatically executes the shut-off procedure to turn off the furnace, effectively avoiding safety risks caused by dry burning or forgetting to turn off the fire.

[0019] It adopts a gear transmission mechanism, including a large gear, a small gear, a driven wheel, and a central shaft with a hexagonal outer diameter. The motor drives the small gear, which in turn drives the main gear and the driven wheel to rotate. The central shaft connects the stove's rotating shaft and the original rotary knob, achieving precise and stable rotation control.

[0020] The outer shell features a double-layer design with an air insulation layer between the two layers. This not only prevents the inner layer from deforming due to high temperatures, extending the product's lifespan, but also enhances the product's aesthetics. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-9This utility model provides a technical solution:

[0035] An automatic gas flame control device includes an intelligent flame-off control module, an intuitive display module, a transmission structure module, and an outer casing protection module. The intelligent flame-off control module, the intuitive display module, and the transmission structure module are all fixedly installed inside the outer casing protection module.

[0036] The intelligent shut-off control module features a built-in STM32F103ZET6 microcontroller. It can automatically shut off the heat according to diverse cooking needs, offering multiple preset standard time options. Users can quickly activate the control with a single button. The microcontroller has multiple buttons 14, each corresponding to a different time setting input, allowing for fine-tuning. For example, it has six buttons 14 with different functions: two for increasing or decreasing the preset time; and the other four for standard time setting options of 15 minutes, 30 minutes, 45 minutes, and 60 minutes, respectively.

[0037] When the timing cycle is completed, the system automatically executes the flameout procedure to shut off the furnace, thereby avoiding safety risks caused by dry burning or forgetting to turn off the fire.

[0038] Intuitive display module: Equipped with an intuitive display interface, it can display the remaining time in real time. It uses an OLED screen to display the remaining time in real time, allowing users to directly observe relevant information and avoid cooking mistakes caused by inaccurate time estimation.

[0039] Transmission structure module: A motor 15 drives a gear set for transmission. The motor 15 is connected to a TB6612 drive module and an MP1584EN step-down module for driving, respectively realizing functions such as motor 15 drive control and system stable power supply. The gear set includes a main gear 5, a pinion 4, a driven wheel 6, and a central shaft 7. Among them, the motor 15 drives the pinion 4, which drives the main gear 5. The main gear 5 and the driven wheel 6 rotate synchronously. The central shaft 7 is used to connect the stove's rotating shaft and the original rotary button, realizing rotation control under the drive of the main shaft, ensuring the stability and accuracy of operation. Specifically, the central shaft 7 adopts a two-layer structure design. Its bottom layer is a hexagonal shell 12, which can be inserted into the central hole 13 of the driven wheel 6, realizing a relative rotatable connection between the driven wheel 6 and the central shaft 7. The rotating shaft of motor 15 is inserted into the central hole 9 of pinion 4. This tight fit allows the rotational power of the motor shaft to be directly transmitted to pinion 4 when the small DC motor is powered on, causing pinion 4 to rotate synchronously. In actual use, the corresponding preset time option or time fine-tuning can be selected according to cooking needs. When the preset time ends, the system controls the motor to start running automatically. Based on the principle of gear transmission, when pinion 4 rotates, the main gear 5 will rotate along with pinion 4 under the interaction force between the teeth, thereby realizing the transmission of power.

[0040] The outer casing protection module: The outer casing adopts a double-layer design, with an air insulation layer between the two layers. This effectively prevents the inner layer from deforming due to high temperatures, providing heat insulation protection, while also improving the product's aesthetics and extending its service life. The double-layer design of the outer casing includes a bottom cover 1 and an upper cover 2. The motor compartment 3 is located inside the bottom cover 1, and a small gear 4 is installed inside the bottom cover 1, directly below the motor compartment 3.

[0041] Specifically, in the further improved scheme, an active actuation point 10 is set on the circumferential surface of the main gear 5, and a passive actuation point 11 is set on the driven wheel 6. When the main gear 5 rotates to the point where the active actuation point 10 contacts the passive actuation point 11 on the driven wheel 6, the main gear 5 will apply a pushing force to the driven wheel 6, causing the driven wheel 6 to rotate, and finally realize the automatic adjustment of the stove device, completing the entire functional process of the gas automatic flame adjustment device.
