Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of smoke exhaust equipment, in particular to a windproof smoke exhaust device. Background Art
[0002] In some industrial production and catering venues, smoke exhaust operations are required to remove harmful substances such as smoke and exhaust gas from the room. Existing smoke exhaust devices generally use smoke exhaust pipes leading to the outdoors to discharge smoke directly into the environment. However, in actual use, some smoke exhaust pipes are affected by the smoke exhaust equipment and surrounding structures and can only exhaust smoke horizontally, not downward. When the wind direction is consistent with the axis of the smoke exhaust pipe, the smoke is difficult to be discharged smoothly due to the influence of wind pressure, and the smoke exhaust effect is poor. In addition, smoke is often accompanied by particulate solid impurities, which can easily cause environmental pollution when discharged directly into the air. Moreover, during the smoke exhaust process, some solid impurities will accumulate in the pipe, affecting the subsequent smoke exhaust effect. Utility Model Content

The fixing blocks 1 and the fixing blocks 2 correspond one to one and are evenly spaced, and the fixing blocks 1 and the fixing blocks 2 are fixed by bolts.
[0006] Based on the above features, the design of fixing block 1, fixing block 2 and bolts makes the installation and disassembly of the wind shield convenient and quick. At the same time, the bolt connection and fixing method is firm and reliable, which can ensure that the wind shield will not loosen or fall off during use, thereby ensuring the stability and safety of the device.
[0007] Furthermore, the filter screen is hemispherical, a snap ring is connected to the edge of the filter screen, the vertical section of the fixing ring is L-shaped to match the snap ring, and the snap ring is clamped between the fixing block 2 and the fixing ring.
[0008] Based on the above characteristics, the hemispherical filter can increase the contact area with the smoke, which is beneficial to improving the filtration efficiency.

The cylindrical exhaust duct reduces wind resistance, thereby increasing its stability. The exhaust fan promotes smoke exhaust, ensuring that smoke can be discharged quickly and smoothly, avoiding backflow.
[0013] Compared with the prior art, the utility model has the following advantages:
[0014] Smoke can be exhausted in multiple directions and is less affected by wind direction: the hemispherical windshield and the windshield are provided with a number of smoke exhaust holes perpendicular to the tangent direction of its side wall. This design allows smoke to be discharged through the smoke exhaust holes in different directions regardless of the wind direction, greatly reducing the influence of wind direction on the smoke exhaust effect.
[0015] The smoke can be filtered and then discharged, which is safe and environmentally friendly: the filter is set between the windshield and the end face of the smoke exhaust duct, which can not only effectively filter impurities in the smoke, reduce pollution to the environment, and reduce safety hazards such as fire, but also prevent dust in the environment from entering the exhaust duct, ensuring the smooth flow of the smoke exhaust duct.
