The system directs the airflow toward the stove, ensuring that the air drawn in is continuously expelled. This helps guide the fumes upward and prevents wind and smoke from spilling out, effectively managing both the air curtain and the smoke exhaust. The suction from the machine is balanced, eliminating the negative pressure resistance typically caused by an open range hood in a closed room. The air curtain’s airflow is immediately captured by the suction hood or the air supply smoke machine, meaning that the air being removed isn’t from inside the room. This significantly reduces issues like heat loss, cold air intrusion, and pollutant leakage, especially during different seasons or weather conditions. Additionally, the air inlet pipe can be equipped with an air purification filter for added efficiency.
As a patented technology, this system offers multiple benefits, including solving the air resistance problems of closed-room range hoods. It uses the air curtain to manage and contain fumes, reducing the negative impact on the indoor environment. The design also features energy efficiency, noise reduction, and the ability to quickly and effectively regulate the amount of air being extracted or supplied. This is achieved because the air curtain reduces indoor negative pressure to zero, allowing the fan to operate more efficiently and create a controlled airflow between the stoves—like a natural wind barrier. This means less pressure is needed, making the system more efficient. The smoking motor doesn’t need to be more powerful than current range hoods, and lower fan speeds help reduce noise levels.
Adjusting the airflow between different stoves is crucial for effective fume removal, especially during cooking. However, in a closed room, a single-suction hood creates strong negative pressure, making it difficult to adjust the fan speed effectively. That’s why people often still smell cooking odors. When using the suction fan or range hood in conjunction with an air curtain stove or air curtain gas stove, changes in airflow volume become much more noticeable and can be adjusted quickly. These functions only work when the range hood or air supply smoke machine is combined with an air curtain stove. As a result, the stove cover design is set to become a key trend in the future of the kitchen smoke purification market.
In terms of application, the air-smoke extraction system, along with matching kitchen cabinets and various types of range hoods, provides a comprehensive solution for kitchen ventilation. Chinese cooking techniques require specific fume purification systems that differ from those used abroad. The dangers of kitchen smoke are well understood, yet current range hoods often fail to perform adequately. Kitchen smoke pollution is a major part of daily life, and the kitchen is particularly challenging in air-conditioned homes, especially under the northern heating self-funding policy. People want to maintain insulation while removing smoke, which makes the advantages of this system even more apparent.
Figure 1 shows the overall kitchen smoke removal system; Figure 2 illustrates the air supply smoke machine; and Figure 3 presents the combination of the kitchen smoke removal system with the air curtain stove.
Hand Held Earth Auger
1. The earth auger consists of a small general gasoline engine, a gearbox and a specially designed drill tool. Suitable for drilling in ground, frozen soil and ice. Widely used in gardens, planting, tree planting, geophysical prospecting, road construction and other fields.
2. The dill bit is made of manganese steel to make it harder. It can work on hard soil, super hard soil, clay, frozen soil, etc.
3. According to the tree species, the ground drill can be equipped with a variety of specifications of the drill to meet the needs of users.
