Detailed Description
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
referring to fig. 1-3, a diesel engine air filter comprises an air filter shell 1, a rain cover 2 is fixedly connected to the top of the air filter shell 1, the rain cover 2 is provided with a skirt edge 3, a gap is reserved between the skirt edge 3 and the outer wall of the air filter shell 1, a filter element 5 support 4 is fixed in the air filter shell 1, a filter element 5 is fixed on the filter element 5 support 4, an air inlet groove 7 is formed in the upper portion of the filter element 5 on the outer wall of the air filter shell 1, an air inlet pipe 6 is connected in the air filter shell 1, air inlet holes 8 are formed in two sides of the air inlet pipe 6, the top of the air inlet pipe 6 penetrates through a cyclone body cover 9 and exceeds the upper surface of the cyclone body cover, and a sealing piece is connected to the top of the air inlet pipe 6.
The utility model is used as follows, when the air filter is installed on the diesel engine, when the extremely low temperature working condition occurs or after the diesel engine is parked for a long time, if the diesel engine can not be started, the sealing element can be unscrewed, then engine oil is dripped into the air inlet pipe 6, when the engine oil is dripped, the top of the air inlet pipe 6 exceeds the upper surface of the cyclone body cover 9 and is positioned at a place with an accessible sight line, so the engine oil can be more accurate when the engine oil is dripped, the starting of the diesel engine can be easier, in addition, the rain cover 2 connected at the top of the air filter shell 1 can prevent rainwater from entering at the side surface of the air filter shell 1, and after the air enters the air inlet groove 7 of the air filter shell 1, the air passes through the filter element 5 and finally enters the air inlet pipe 6 through the air inlet hole 8 of the air inlet pipe 6.
Further, the top of the air inlet pipe 6 is provided with a threaded part 10, and the sealing element is a nut 11 and is connected to the threaded part 10 in a sealing way through the nut 11.
