Breather pipe shield

The utility model discloses a breather pipe shield, wherein, this shield includes: the shell subassembly, liner assembly sets up in the inside of shell subassembly, a last airflow pipeline and the 2nd airflow pipeline of being formed with of liner assembly, and an airflow pipeline is linked together with the breather pipe, and the 2nd airflow pipeline and external environment are linked together, filtering component sets up in the shell subassembly, connects an airflow pipeline and the 2nd airflow pipeline on the liner assembly, the filterable air that is got into the breather pipe by external environment. The utility model discloses a breather pipe shield can make the atmosphere pass through during an airflow pipeline on the liner assembly gets into the shield, through the impurity such as dust among filtering component's the filtration de aeration, and then in getting into oil tank breather through another airflow pipeline, has prevented effectively that the impurity such as dust in the air from getting int
