Description

Technical Field

[0001] The utility model relates to the technical field of exhaust pipe accessories, in particular to an umbrella-shaped hood. Background Art

[0002] The burning of household loose coal is one of the main causes of winter air pollution. According to my country's current energy structure, burning coal for heating in northern rural areas in winter will remain the mainstream heating method for a long period of time. As a matching accessory for household coal-fired stove chimneys, the wind hood plays a role in ventilation and rain protection. The main function of the mainstream household coal-fired stove wind hood is to connect to the chimney to play a role in ventilation and rain protection. The air outlet is small, and the wind force is small when the coal-fired stove burns to form a negative pressure exhaust, which is not conducive to the full combustion of the coal in the furnace.

[0003] In the related technology, such as the Chinese patent with application number: "201922359165.9", its name is: "A household coal-fired stove umbrella-shaped hood", including an umbrella-shaped hood, a cylindrical hood and a guide air duct opening. The lower end of the umbrella-shaped hood is connected to the cylindrical hood, and the cylindrical hood is provided with a guide air duct opening. The guide air duct opening is inclined downward toward the outside, and the guide air duct opening is connected to the exhaust duct inside the cylindrical hood. The exhaust duct at the bottom of the cylindrical hood is connected to the chimney duct. The guide air duct opening is made on the cylindrical hood according to the principles of aerodynamics, which plays an important role in improving combustion efficiency and reducing pollution emissions. It increases the air outlet, enhances exhaust, and is more conducive to the full combustion of coal. It can both quickly exhaust air and prevent rain, snow and strong wind backflow.

[0004] The above patent also has the following disadvantages: 1. When it rains, snows or has strong winds, rain or foreign matter is more likely to enter the cylinder directly from the outer cylinder and affect the operation of the burner; 2. When the gas encounters a large temperature difference in the air, the moisture or droplets generated will float in the air through the exhaust channel, and the impurities contained in the gas will cause environmental pollution.
