Abstract
An air filter comprises an air inlet, a filter body and a flow guiding device, and the flow guiding device is arranged between the air inlet and the filter body. Due to the fact that the flow guiding device is arranged between the air inlet of the air filter and the filter body, the problems that a partial surface of the filter body is overloaded and too many impurities accumulate in the filter body are avoided, filtering efficiency of the air filter is improved, and the service life of the air filter is prolonged.
Description
Technical field
The utility model belongs to the air-strainer field, particularly relates to a kind of air-strainer that reduces surface loading.
Background technique
The effect of air-strainer is the airborne suspending particulate matter that filtering enters cylinder, to reduce the wearing and tearing of cylinder, piston and piston ring.In the required three kinds of media of engine operation, the air consumption is maximum, and comes from atmosphere.If air-strainer is the airborne suspending particulate matter of filtering effectively, light then accelerate the wearing and tearing of cylinder, piston and piston ring, heavy then cause cylinder to pull, shorten the working life of motor.
And in the existing air-strainer, in design without air guide device, cause air-strainer local surfaces overload and impurity to be saved bit by bit too much, and reduced the filter efficiency of air-strainer, shortened the working life of air-strainer.
Summary of the invention
The technical problem that (one) will solve
The technical problems to be solved in the utility model is: prevent that air-strainer local surfaces overload and impurity from saving bit by bit too much, improve the filter efficiency of air-strainer, prolong the working life of air-strainer.
(2) technological scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of air-strainer.
Wherein, described air-strainer comprises suction port, filter cleaner body and flow guide device, is provided with flow guide device between suction port and filter cleaner body.
Preferably, described air-strainer also comprises housing, and described filter cleaner body is arranged in the housing, and described housing comprises suction tude and steam outlet pipe, and described flow guide device is arranged in the suction tude.
Preferably, described flow guide device is air guide sleeve.
Preferably, described housing also comprises sealing cover, is used for seal casinghousing.
Preferably, described housing is the PP injection-moulded housing.
Preferably, described filter cleaner body is cylindrical.
(3) beneficial effect
Technique scheme has following advantage: the utility model is by being provided with flow guide device between the suction port of filter cleaner and filter cleaner body, prevented that filter cleaner body local surfaces overload and impurity from saving bit by bit too much, improve the filter efficiency of air-strainer, thereby prolonged the working life of air-strainer.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model structural representation.
Wherein, 1: housing; 2: the filter cleaner body; 3: suction tude; 4: steam outlet pipe; 5: sealing cover; 6: flow guide device.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, be a kind of embodiment's of the present utility model structural representation, this air-strainer comprises suction port, filter cleaner body 2 and flow guide device 6, is provided with flow guide device 6 between suction port and air-strainer body 2.The utility model is by being provided with flow guide device between the suction port of filter cleaner and filter cleaner body, prevented that filter cleaner body local surfaces overload and impurity from saving bit by bit too much, improve the filter efficiency of air-strainer, thereby prolonged the working life of air-strainer.
Filter cleaner body of the present utility model can be various suitable filter cleaners, and its structure also can be various shapes, and the filter cleaner body is preferably cylindrical filter cleaner.Installation and use for the ease of the filter cleaner body, preferably, described air-strainer also comprises housing 1, described filter cleaner body 2 is arranged in the housing 1, described housing 1 comprises suction tude 3 and steam outlet pipe 4, described flow guide device 6 is arranged in the suction tude 3, and the air-flow of air enters suction tude (airflow direction is the direction of arrow the figure) from suction port, enters the filter cleaner body by suction tude via flow guide device again and filters.Flow guide device of the present utility model can for various suitable air guide structures, be preferably air guide sleeve.Be provided with flow guide device in this embodiment's the suction tude 3, prevented the air inlet mouth of pipe air-strainer local surfaces overload and the impurity of position are saved bit by bit too much, improved the filter efficiency of air-strainer, thereby prolonged the working life of air-strainer.
Again consult Fig. 1, housing 1 of the present utility model also comprises sealing cover 5, is used for seal casinghousing 1.Housing of the present utility model can be various suitable shapes and material, and preferably, housing is the PP injection-moulded housing, thereby so that this air-strainer quality is light, long service life.
As can be seen from the above embodiments, the utility model is by being provided with flow guide device between the suction port of filter cleaner and filter cleaner body, prevented that filter cleaner body local surfaces overload and impurity from saving bit by bit too much, improve the filter efficiency of air-strainer, thereby prolonged the working life of air-strainer.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
