Creating a Smoke-Free Kitchen with Advanced Technology

Respiratory health is the foundation of a good life, yet kitchen smoke often becomes a hidden threat. We all aspire for a home where the stove is bustling with oil, the living room filled with family, no roaring machine sounds, and no nose-wrenching smoke. Only fresh air and laughter accompany the cooking experience.

Now, such a scene has become a reality at AWE 2026. On March 12th, 3月12日, Sohu founder, Board Chairman and CEO, and physicist Dr. Zhang Yansong brought the "Everything Has Its Reason" program to the AWE Mi Smart Smoke Extractor booth. He used physical formulas to decode the fluid mechanics of the Mi Smart Smoke Extractor and revealed to the audience how technology can help kitchens bid farewell to smoke PM2.5 particles.

Zhang Yansong exclaimed that the Mi Smart Smoke Extractor is highly revolutionary. It improves the smoke extraction effect through dynamic particle collection technology. Traditional smoke extractors only absorb part of the smoke, but the Mi Smart Smoke Extractor, through the collaborative action of four low-pressure vortices, rearward high-speed airflow, and barrier curtains above the pot, can absorb different types of pollutants such as PM2.5 and PM10 in the smoke.

What's the difference between a "smoke extractor" and an "oil smoke extractor"?

The kitchen, which should be a place for creating delicious food and warmth, has become a "smoke-heavy ground" for many people in reality.

Many people dislike cooking because they can't stand the smell of smoke on their clothes and hair after cooking. More alarmingly, the "high-heat rapid stir-frying" commonly used in Chinese cuisine produces a large amount of PM2.5. Once these tiny particles are inhaled, they will lead to a higher incidence of lung diseases.

Data shows that the incidence of lung diseases in China is 6 times that of Europe and America. In 2023, the indoor air quality standard released by China showed that indoor PM2.5 should be less than 50μg/m³, and kitchen smoke is one of the main sources of indoor air pollution.

Traditional oil smoke extractors use negative pressure suction technology, relying on the fan to form negative pressure at the suction port to produce suction to draw in smoke. This can be categorized as "passive exhaust smoke." This method has a fixed suction area, and when the smoke rises too fast or over a wide range, it is easy to escape outside the suction area, leading to "smoke leakage" and "nose-wrenching smoke."

The biggest difference between the Mi Smart Smoke Extractor and general oil smoke extractors is that it not only absorbs visible kitchen smoke but also removes the smoke smell, creating a comfortable and open cooking environment, and freeing users from the trouble of daily cleaning. It allows users to enjoy cooking while also having fresh and healthy air.

In particular, this is achieved through Xiaomi's three core technologies: dynamic particle collection technology, high-speed soft noise reduction technology, and oil-free net no-cleaning technology. It is the collaborative effect of these three core technologies that enables Xiaomi to truly achieve the leap from "oil smoke extractor" to "smoke extractor."

When cooking no longer needs to endure smoke, and when stir-frying can also be a refreshing experience, the kitchen truly returns to its original form.

Zhang Yansong reveals the fluid mechanics secrets of the Mi Smart Smoke Extractor

The core of the Mi Smart Smoke Extractor is the dynamic particle collection technology, which uses a combination of three airflows to control smoke, PM2.5 particles, and smoke smell, becoming an innovative solution in the industry.

In the live broadcast, Zhang Yansong shared an in-depth and interesting explanation of the physical principles contained in the dynamic particle collection technology.

Zhang Yansong explaining dynamic particle collection technology

He said that kitchen smoke is a headache because Chinese high-temperature cooking causes uncompletely cracked edible oil and carbonized food to form ultra-fine particles of 0.5~2.5 μm. According to Stokes' law, they are difficult to settle because the air resistance they experience is greater than gravity, and they can only remain suspended in the air for a long time.

When cooking, the air above the pot is rapidly expanded and rises, and gradually diffuses horizontally, forming a conical "hot plume." When the "hot plume" rises to the height of 0.8m where traditional oil smoke extractors are installed, the diffused area has reached four times the area of the stove, and the top kinetic energy is weak and extremely unstable. At this time, even a slight movement such as stir-frying, walking, or breathing can easily scatter this fragile smoke, and smoke particles and odor molecules will constantly escape outward, leading to smoke-filled kitchens.

Dynamic particle collection technology in action

Traditional oil smoke extractors usually adopt a high-position "passive static pressure suction" scheme, which is not large enough in area and depth, and is difficult to absorb all the continuously diffused smoke. In comparison, the Mi Smart Smoke Extractor adopts a four-vortex collection gas spiral scheme, setting two groups of adjacent counter-rotating gas spirals on each stove to improve collection efficiency. After using the horizontal "double vortex net bag" to gather particles, the smoke is further discharged vertically through rearward high-speed airflow.

For occasionally escaping smoke particles, the Mi Smart Smoke Extractor deploys the third line of defense—the barrier curtain to prevent escape—above the unstable top of the "hot plume," locking the smoke particles inside through physical isolation.

The "low-position active flow field control" strategy proposed by the Mi Smart Smoke Extractor breaks the deadlock through three different airflow control schemes in the lower, middle, and upper sections of the "hot plume" generated during cooking: source vortex capture, rearward high-speed instant suction, and top curtain prevention of escape. It no longer relies on passive suction but instead actively reconstructs the space macro flow field with overwhelming kinetic energy.

The warmth of science, hidden in the kitchen

Of course, the experience of the Mi Smart Smoke Extractor, which is different from traditional smoke extractors, is not just about "smoke extraction." It also allows users to focus on enjoying the cooking fun and makes daily maintenance more convenient. These thoughtful experiences come from Xiaomi's high-speed soft noise reduction technology and easy-to-clean no-cleaning design.

Many netizens wonder if the Mi Smart Smoke Extractor with such high flow rate and strong suction will also be very noisy. Xiaomi's Ecology Chain Deputy General Manager Yu Xinwang introduced in the live broadcast that Xiaomi has adopted multiple silent design methods for noise reduction.

For example, the wind wheel adopts biomimetic design from the aviation field, with many evenly distributed teeth on the blades, which greatly reduces noise while maintaining strong suction, so that the cooking process is quiet and undisturbed.

Behind this, the biomimetic tooth design disperses the originally regular noise into multiple sound sources, allowing sound waves to cancel each other out and break up large vortices into small ones, reducing noise energy.

For the pain point of traditional smoke extractors' suction attenuation after long-term use, the easy-to-clean no-cleaning design of the Mi Smart Smoke Extractor tackles this from two aspects: first, the surface of the wind wheel blade is coated with an oil-resistant coating to reduce oil污 attachment; second, it is equipped with a high-speed motor and high-speed airflow technology, where the high-speed airflow forms an air film on the surface of the wind wheel, blocking oil droplets from adhering.

Zhang Yansong explained that a higher rotation speed can actually produce tremendous centrifugal force, and the size of the centrifugal force is proportional to the square of the rotation speed. Under this tremendous centrifugal force, oil droplets will be quickly thrown off.

In order to demonstrate the ease of cleaning of the machine, the Xiaomi team also prepared spicy sauce with oil. The test found that the oil dropped off quickly and did not have strong adhesion, only needing a slight wipe to clean it.

From smoke extraction to noise reduction, to easy cleaning, every technical breakthrough of the Mi Smart Smoke Extractor is supported by a profound knowledge system.

Zhang Yansong explained in the field the complex scientific principles involved, such as how to use aerodynamics to control smoke, how to use biomimetic design for noise reduction, and how to use the principle of centrifugal force to remove oil污.

And it is based on the most simple and sincere初衷: creating a pleasant cooking experience, protecting the respiratory health of the whole family, and making the kitchen no longer a hidden disaster area of PM2.5, so that you can safely open the door and stir-fry with confidence.
