Technical Field
[0001] The utility model relates to an air distribution device, in particular to an air distribution device used in a wall-mounted boiler system, which can effectively introduce air and process waste gas to improve combustion efficiency. Background Art
[0002] As we all know, wall-mounted boilers are highly efficient heating devices widely used in homes and commercial buildings. They primarily heat water or air by burning gas or other fuels to provide indoor heating and domestic hot water. However, the air handling units in existing wall-mounted boilers often suffer from complex designs and difficult maintenance. A wall-mounted boiler's air handling system has a crucial impact on its overall performance.
[0003] In the prior art, the main function of an air handling device is to provide sufficient oxygen for combustion and to effectively discharge the exhaust gas generated by combustion. However, conventional air handling devices have many disadvantages, which are described in detail below.
[0004] First, the air handling devices in the prior art usually include a complex duct system and multiple filter elements. Although these systems can filter air and discharge exhaust gas to a certain extent, their complex structure leads to high production and maintenance costs.
[0005] Secondly, the structural design of the existing air handling device is not conducive to maintenance and cleaning. After long-term use, dust and impurities are easily accumulated, affecting air circulation and combustion effects, and increasing maintenance costs and labor intensity.
[0006] Thirdly, existing air handling systems are inefficient in handling the flow of air and exhaust gases. For example, the duct design in traditional systems often fails to fully utilize the pressure difference between the air and exhaust gases, resulting in poor air flow, which in turn affects combustion efficiency and exhaust emissions.
[0007] Finally, another major issue with existing technology is that air handling unit designs often lack adaptability to diverse installation environments. When used outdoors, many units lack effective drainage systems, making them susceptible to rainwater damage or performance degradation. Conversely, when used indoors, air handling units may not be able to fully function due to space constraints.
[0008] In summary, the air box in the prior art has obvious deficiencies in air distribution, maintenance convenience, and environmental adaptability. Therefore, an improved air box structure is needed to solve these problems. Summary of the Invention
[0009] The technical solution adopted by the utility model is: an air distribution device for a wall-mounted boiler, characterized in that it includes a top cover (10) and a box body (20), wherein the top cover (10) is covered on the box body (20), and the top cover (10) has a main hole (11) and an air introduction ring (12), wherein the main hole (11) is arranged in the air introduction ring (12), and the box body (20) is provided with an exhaust gas discharge pipe (30), wherein the exhaust gas discharge pipe (30) is passed through the main hole (11), and an air introduction channel (40) is formed between the exhaust gas discharge pipe (30) and the air introduction ring (12), and the air introduction channel (40) allows external air (A) to enter the box body (20) through the air introduction channel (40).
[0010] The present invention provides an air distribution device for a wall-mounted boiler, which has a simple structure and low production and maintenance costs. The air distribution device comprises an air box having a top cover and a body, wherein the top cover has an opening larger than an exhaust duct, and the exhaust duct is passed through the opening. The other end of the exhaust duct is connected to a burner to discharge exhaust gas. This design not only simplifies the structure of the air box but also reduces production and maintenance costs.
[0011] The utility model provides an air distribution device for a wall-mounted boiler. The structure of the air distribution device improves the efficiency in processing the flow of air and exhaust gas. The design of the exhaust gas duct and the top cover opening fully utilizes the pressure difference between the flow of air and exhaust gas, ensuring the smooth flow of air, thereby improving the combustion efficiency and the exhaust gas emission effect.
[0012] The utility model provides an air distribution device for a wall-mounted boiler. The air distribution device is designed to be easy to disassemble and clean. The simplified structure of the air box reduces the accumulation of dust and impurities, ensures air circulation and combustion effects, and reduces maintenance costs and labor intensity after long-term use.
[0013] The utility model provides an air distribution device for a wall-mounted boiler. The air distribution device is designed to have strong environmental adaptability. The air box includes a rainwater pipe at the bottom, which can be connected to the drainage system. This prevents the device from being affected by rain when used outdoors, ensuring stable operation of the device. When used indoors, the compact design of the air box adapts to limited space and ensures that the device functions fully.
[0014] In summary, the present invention improves the overall performance and adaptability of the equipment by improving the structure and design of the air distribution device, and solves the problems existing in the prior art such as high production and maintenance costs, poor air circulation, low combustion efficiency, and poor environmental adaptability.

[0022] like Figures 1 to 7 As shown, an air distribution device for a wall-mounted boiler comprises a top cover (10) and a box body (20), wherein the top cover (10) is arranged on the box body (20).
[0023] like Figures 1 to 2 As shown, the top cover (10) has a main hole (11) and an air introduction ring (12), wherein the main hole (11) is arranged in the air introduction ring (12).
[0024] An exhaust gas discharge pipe (30) is provided on the box body (20), wherein the exhaust gas discharge pipe (30) is passed through the main opening (11).
[0025] An air introduction channel (40) is formed between the exhaust gas discharge pipe (30) and the air introduction ring (12).
[0026] That is, the outer diameter of the main opening (11) is larger than the outer diameter of the exhaust gas discharge pipe (30). When the exhaust gas discharge pipe (30) is inserted into the main opening (11), the air introduction channel (40) is formed between the air introduction ring (12) and the exhaust gas discharge pipe (30). The air introduction channel (40) is located around the outside of the exhaust gas discharge pipe (30).
[0027] like Figure 2As shown, in practice, during the combustion process of the wall-mounted boiler, the combustion in the burner generates high-temperature and high-pressure exhaust gas (E), and the exhaust gas (E) generated in the burner is discharged into the atmosphere through the exhaust gas exhaust pipe (30).
[0028] The air introduction channel (40) allows external air (A) to enter the box body (20) through the air introduction channel (40), so that the air (A) can enter the burner to provide oxygen required for combustion.
[0029] As described above, the main design idea of the present invention is to open the main hole (11) on the top cover (10) of the air distribution device, and to provide the air introduction ring (12) on the outer diameter of the main hole (11). At the same time, the exhaust gas discharge pipe (30) smaller than the outer diameter of the main hole (11) is passed through the main hole (11), thereby forming the air introduction channel (40) between the exhaust gas discharge pipe (30) and the air introduction ring (12). By utilizing the pressure difference between the flow of the air (A) and the exhaust gas (E), the air (A) with a higher external atmospheric pressure enters the box body (20) through the air introduction channel (40), and the high-pressure exhaust gas (E) generated in the burner is discharged from the box body (20) to the atmosphere through the exhaust gas discharge pipe (30), thereby achieving effective diversion and flow control of the air (A) and the exhaust gas (E), ensuring the normal operation and efficient combustion of the burner, and avoiding the problem of poor air flow in traditional designs.
