[0034] The base 100 has a frustum-shaped structure, which effectively increases the stability of the stove's contact with the surface it is placed on. Multiple support feet 101 are evenly distributed on its bottom, each with anti-slip textures to further enhance the stability of the stove and prevent it from sliding during use. The top surface of the base 100 has several mounting holes 102 for easy assembly and fixing with other components.

[0035] The furnace shell 200 is securely connected to the mounting holes 102 on the top surface of the base 100 using screws, ensuring a stable and reliable connection. The furnace shell 200 is made of a high-temperature resistant and corrosion-resistant metal material, such as precision-cast ductile iron, making it sturdy and durable, able to withstand high-temperature environments, guaranteeing the lifespan of the stove, and resistant to corrosion. The top surface of the furnace shell 200 is provided with protrusions 201 to support the cookware, making the cookware more stable. A burner head 300 is installed inside the furnace shell 200, fixed in the middle position. One side of the burner head 300 is connected to an air inlet pipe 301, which supplies fuel gas to the burner head 300. A micro fan is installed at the end of the air inlet pipe 301 to supply air into it. This micro fan is a variable-speed fan; by adjusting the fan speed, the amount of air supplied is controlled, thereby achieving precise premixing of fuel gas and air within the air inlet pipe 301, ensuring good combustion performance.

[0036] A bracket 400 is mounted on the side of the furnace shell 200. The bracket 400 has an L-shaped structure, which saves space while effectively supporting and arranging related components.

[0037] Both the micro fan and the ignition assembly are connected to the control module, which includes a controller, sensor components, and a power module.

[0038] Controller: As the core of the entire micro fan control system, it typically employs a microprocessor or microcontroller. It receives signals from sensor components and controls the micro fan's operation according to preset programs and algorithms. For example, when a stove ignition signal is detected, the controller quickly starts the micro fan and adjusts its speed according to a preset gas-air mixing ratio to ensure optimal premixing of gas and air within the intake pipe.

[0039] Sensor assembly: This includes various sensors, primarily a gas concentration sensor and an air flow sensor. The gas concentration sensor is installed in the air intake pipe near the burner head to monitor the gas concentration in the air intake pipe in real time.

[0040] An air flow sensor is installed at the outlet of the miniature fan to accurately measure the air flow entering the intake pipe and transmit the data to the controller. The controller then uses the air flow to precisely control the amount of gas input, ensuring that the gas and air are always mixed in the appropriate ratio.

[0041] Power module: Provides a stable power supply for the entire micro wind turbine control system. It converts external AC mains power (such as 220V AC) into DC voltage (such as common 12V or 24V) suitable for the controller, sensors, and micro wind turbine. The power module also features overvoltage protection, overcurrent protection, and filtering functions to prevent damage to the control system caused by voltage fluctuations or excessive current, ensuring stable and reliable operation of the entire system.

[0042] The burner head 300 includes several flame holes 302 and a flame concentrating ring 303 is installed on the burner head 300. The flame concentrating ring 303 has a ring structure, and the flames emitted from the flame holes 302 are distributed within the flame concentrating ring 303. The flame concentrating ring 303 can concentrate the flames, improve heat utilization, and make cooking more efficient.

[0043] The ignition assembly includes an igniter and an ignition needle. The igniter and the ignition needle are electrically connected. The ignition needle is located above the burner head 300. The high voltage generated by the igniter causes the ignition needle to discharge, thereby igniting the gas mixture. The ignition method is simple and reliable.

[0044] Assembly process:

[0045] Place the base 100 in a suitable position, ensuring that the support feet 101 are in stable contact with the surface.

[0046] The furnace shell 200 is fixedly connected to the mounting hole 102 on the top surface of the base 100 by screws.

[0047] A burner head 300 is installed inside the furnace shell 200, and an air inlet pipe 301 is connected to the burner head 300.

[0048] Install the miniature fan at the end of the air intake pipe 301 to ensure that it can deliver air into the air intake pipe normally.

[0055] Adjust the speed of the miniature fan according to cooking needs to control the amount of air delivered and achieve premixing of gas and air.

[0056] Pressing the ignition switch 402 causes the igniter to generate high voltage, which discharges the ignition needle and ignites the premixed gas in the air intake pipe. The flame is ejected from the flame hole 302 of the burner head 300 and distributed in the flame ring 303 to heat and cook the cookware placed on the boss 201 on the top surface of the furnace shell 200.

[0057] During the cooking process, the heat intensity and the gas-air mixing ratio can be adjusted at any time according to the actual situation via the flow regulating valve 401 and the speed of the micro fan.

[0058] This utility model of a premixed stove uses a fan to assist combustion, ensuring complete combustion of the gas, resulting in energy saving and environmental protection. Furthermore, the ignition assembly is equipped with a flameout protection device, and it uses low-pressure gas or piped natural gas, ensuring safety and reliability.
