Technical Field
[0001] This utility model relates to the field of air purification equipment technology, and in particular to an energy-saving and environmentally friendly air purification fan. Background Technology
[0002] Axial flow fans are ventilation devices that rely on the rotation of an impeller to propel gas along the axial direction. They are widely used for ventilation in industrial plants, warehouses, office buildings, laboratories, and other places. With the increasing emphasis on energy conservation and environmental protection, higher requirements are being placed on the performance of axial flow fans. They not only need to have good ventilation efficiency but also reduce noise pollution during operation and achieve energy-saving operation.
[0003] Patent No. CN202511189291.8 discloses a high-efficiency and energy-saving axial flow fan, which is bolted to a bracket at the bottom of a cylindrical shell. A silencing mechanism is connected to the inner wall of the cylindrical shell, and a motor is connected inside the cylindrical shell, with fan blades connected to both ends of the motor. The silencing mechanism includes two silencing sleeves connected inside the cylindrical shell, with air guide rings connected to the ends of the two sleeves that are far apart from each other. Each silencing sleeve includes an annular silencing plate connected to the inner wall of the cylindrical shell, and a silencing foam board disposed between the annular silencing plate and the cylindrical shell. This invention improves ventilation efficiency while reducing noise, avoiding the drawbacks of single silencing potentially increasing wind resistance or single air guide potentially exacerbating noise. However, this device has the following problems: firstly, it has a complex structure and high installation cost; secondly, it has high energy consumption, poor purification effect, and high maintenance cost.

Then, the motor is a brushless DC inverter motor, and the guide plate is filled with sound insulation cotton. This solves the technical problems of poor energy saving, poor sound insulation and high installation and maintenance costs of the existing axial flow purification fan.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0026] Example 1
[0027] like Figures 1 to 6 As shown, this utility model provides an energy-saving and environmentally friendly air purifying fan, including a mounting cover 1. The mounting cover 1 has an axial flow fan structure 2 at its center, and a connecting mounting hole 11 at the upper right end of the mounting cover 1. The mounting handles 12 are located at the center of the left and right sides of the front end of the mounting cover 1, and mounting clips 13 are located at the center of the outer sides of the four rear sides of the mounting cover 1. The guide plates 3 are fixedly connected to the inner left and right sides of the rear end of the mounting cover 1, and the main shaft 31 is fixedly connected to the center of the inner side of the rear end of the mounting cover 1. The front end of the main shaft 31 is fixedly connected to a noise-proof guide plate 32, and the front end center of the noise-proof guide plate 32 is fixedly connected to a mounting plate 33.
[0028] An axial flow fan structure 2 includes a filter screen cover 21. The rear end of the filter screen cover 21 is fixedly connected to a mounting cover 1, and a filter screen 22 is provided at the center of the filter screen cover 21. The rear end of the filter screen 22 is fixedly connected to a horn block 23. The rear end of the horn block 23 is connected to a blade fixing horn block 24 by a bearing. The rear end of the blade fixing horn block 24 is uniformly fixedly connected to blades 25. The rear end of the blades 25 is fixedly connected to a disc 26. The center of the disc 26 is fixedly connected to a rotating shaft 27. The rear end of the rotating shaft 27 is fixedly connected to an output shaft. The rear end of the output shaft is fixedly connected to a motor. The rear end of the motor is fixedly connected to a mounting plate 33.
[0029] Furthermore, the main shaft 31 is an isosceles triangle, and fixing plates 311 are fixedly connected to both the upper and lower sides of the main shaft 31. Each fixing plate 311 has a connecting hole 312 at its center, and each fixing plate 311 is fixedly connected to a mounting cover 1. Second fixing plates 313 are fixedly connected to the left and right sides of the main shaft 31, and the second fixing plates 313 are fixedly connected to a noise-reducing guide plate 32. The main shaft 31 is set as an isosceles triangle, which, together with the guide plate 3 and the guide rectangular plate 321, can cooperate with air guidance to ensure that the axial flow fan exhausts air more quickly and the air purification is more significant.
[0030] Furthermore, the noise-reducing guide plate 32 is symmetrically and fixedly connected to the guide rectangular plate 321 on the left and right sides. The guide rectangular plate 321 is set at an angle to the front end, and the setting of the guide rectangular plate 321 ensures better flow guidance effect.
[0031] Furthermore, both the flow guide plate 3 and the noise-proof flow guide plate 32 are hollow metal plates, and the inner sides of both the flow guide plate 3 and the noise-proof flow guide plate 32 are filled with sound insulation cotton. The filling of sound insulation cotton makes the sound insulation effect of the entire device better, and the overall environmental protection performance is better.
[0032] Furthermore, the filter 22 is a nano-silver fiber filter, the blade 25 is a whale fin structure blade, and the motor is a brushless DC inverter motor. The nano-silver fiber filter inhibits the growth of microorganisms and reduces the frequency of filter replacement. The whale fin blades result in low wind resistance and low blade rotation noise. The brushless DC inverter motor ensures low overall energy consumption and is more energy-efficient.
[0033] Furthermore, a set of arc-shaped guide plates 251 are provided on the outer side of the blade 25. One end of the arc-shaped guide plate 251 is fixedly connected to the mounting cover 1, and the other end is fixedly connected to the noise-reducing guide plate 32. The setting of the arc-shaped guide plate 251 ensures that the air in the entire mounting cover 1 enters the blade 25 position conveniently along the guide plate, eliminates inlet vortices, improves uneven inlet pressure distribution, and prevents cavitation caused by local low-pressure areas. Moreover, the arc-shaped guide plate 251 makes the airflow pre-swirl direction consistent with the rotation of the blade 25, reducing impact loss and improving air purification efficiency.
[0034] Working process: First, the worker uses the installation handle 12 to place the installation cover 1 in the installation position for installation. Then, the motor starts working, driving the output shaft to rotate. The rotation of the output shaft drives the rotating shaft 27 fixed to it to rotate, thereby causing the blades 25 to rotate. The rotation of the blades 25 drives the blade-fixed horn block 24 to rotate, and also drives the disc 26 to rotate, so that the fan works normally. The principle is simple. Moreover, a guide plate 3, a noise-proof guide plate 32, and an arc-shaped guide plate 251 are set at the rear end of the axial flow fan structure 2. These can break up large-scale vortices and transfer low-frequency noise energy to high-frequency. Combined with sound insulation cotton, the overall sound insulation effect is better. The whole structure has low energy consumption, good sound insulation and environmental protection effect, long maintenance cycle, and low cost.
