The conventional breathing port is processed by adopting high plastic products, a product processing die needs to be arranged, the manufacturing process is complex, the processing period is long, and the cost for manufacturing products is high. The plastic product has poor aging resistance and is easy to damage and damage in the blade operation process. The conventional breathing port is installed in the front edge area and the rear edge area of the blade, and both sides of the conventional breathing port are all installed, so that the influence on the actual operation process of the blade after the conventional breathing port is installed is lack of detailed data comparison, and the cost of the blade product is extremely easy to increase gradually.
