Abstract
An air filter of a power generator solves the problem of oil dirt accumulation in the air filter in the prior art when waste gas of a cylinder end is fed into a carburetor through the air filter. The air filter comprises a casing which is provided with an air inlet and an air outlet and is characterized in that a drainage block for guiding air entering from the air inlet into the air outlet is additionally arranged in the casing. The air inlet is used for leading in the waste gas of the cylinder end, and the additionally arranged drainage block directly guides the air entering from the air inlet to the air outlet, so that the retaining time of the waste gas of the cylinder end in the air filter and entering from the air inlet is reduced, the possibility of contact between the impurities and the inner wall of the casing of the air filter is reduced, oil dirt in the waste gas can directly enter the carburetor and the like through the air outlet along with flowing of the waste gas, the problem of oil dirt accumulating in the air filter is solved, and external air can enter from other inlets of the air filter, can be filtered by a filter core and then enters the air outlet.
Description
Technical field
The utility model relates to a kind of generator air filter.
Background technique
Contain a certain amount of oil content in the waste gas that engine cylinder head is discharged, for taking full advantage of fuel and avoiding environmental pollution, usually generator set can be sent into cylinder head waste gas in the Carburetor by air filter, usually the suction port of air filter is located at the top of housing, filter core is the vertical direction setting, cylinder head waste gas can act directly on the inner walls after at a high speed entering air filter, and therefore entrained oil material etc. also impinges upon on the inner walls and adhere in the gas, thereby causes greasy dirt accumulation in the air filter.
The model utility content
The utility model is intended to provide a kind of generator air filter, when solving that cylinder head waste gas is sent into Carburetor by air filter in the prior art, causes the problem that greasy dirt is piled up in the air filter.
Technological scheme one: the generator air filter in this programme, include housing, housing is provided with suction port and air outlet, it is characterized in that, is provided with the drainage piece that guides to the air outlet for the gas that suction port is entered in the housing.
Described inlet gas is used for access cylinder head waste gas, the drainage piece of setting up directly guides to the air outlet with the gas that suction port enters, reduced the holdup time of cylinder head waste gas in air filter that suction port enters, reduced simultaneously the probability that impurity contacts with the air filter inner walls in the waste gas, greasy dirts in the waste gas etc. can be with waste gas streams to directly enter the equipment such as Carburetor by the air outlet, solved the problem that greasy dirt is piled up in the air filter, outside air enters by other imports of air filter, by entering described air outlet behind the filter element filtering.
Technological scheme two: further, described drainage piece is arranged on the opposite position of suction port and air outlet, is provided with drainage trough towards the side of air outlet on the drainage piece.The described drainage trough that is arranged on the opposite position of suction port and air outlet can be introduced the air outlet with cylinder head waste gas more efficiently.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the schematic representation in the utility model embodiment middle shell outside;
Fig. 2 is the schematic representation that the utility model embodiment middle shell inboard is not provided with activity drainage piece;
Fig. 3 is the schematic representation that the utility model embodiment middle shell inboard is provided with activity drainage piece;
Fig. 4 is the schematic representation of activity drainage piece among the utility model embodiment;
Fig. 5 is the schematic representation of another angle of activity drainage piece among the utility model embodiment.
Embodiment
Fig. 1 is relative two sides with Fig. 2 displaying: the housing among the figure only is the part of air filter housing, housing is provided with prismatoidal projection, on the housing triangular hill above be provided with inlet hole 1, the side of triangular hill is provided with air outlet hole 2 on the housing, inlet hole 1 can be used for being connected with the relief opening of engine cylinder head, and air outlet hole 2 can be used for being connected with Carburetor.
As shown in Figures 2 and 3: be provided with the drainage channel that the drainage piece limits in the inside of air filter, the fixedly drainage piece 31 and dismountable activity drainage piece 32 amalgamations that are fixed on the housing consist of the drainage piece.The top of drainage piece is provided with inlet hole 1 towards, drainage suction port 41 corresponding to size, and the side of drainage piece is provided with corresponding with air outlet hole 2 gas port 42 that drains, drainage suction port 41 and drain 42 of gas ports and be provided with drainage trough 4.
The cylinder head waste gas of introducing from inlet hole 1 directly pours in the drainage suction port 41, and then in fixing stopping under the guiding function of drainage piece 31, activity drainage piece 32 and partial shell, cylinder head waste gas flows to air outlet hole 2 from draining gas port 42.
Fig. 4 and Fig. 5 are the shape schematic representation of dismountable activity drainage piece 32.
Above-described only is embodiment of the present utility model, and the general knowledge such as known concrete structure and characteristic are not done too much description at this in the scheme.Should be understood that; for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (2)
1. the generator air filter includes housing, and housing is provided with suction port and air outlet, it is characterized in that, is provided with the drainage piece that guides to the air outlet for the gas that suction port is entered in the housing.
2. generator air filter according to claim 1 is characterized in that, described drainage piece is arranged on the opposite position of suction port and air outlet, is provided with drainage trough towards the side of air outlet on the drainage piece.
