As the restriction to aforesaid way, described upper shell and lower shell body are removably fixed with.
As the restriction to aforesaid way, described upper shell and lower shell body are connected by bolt.The mode that adopts bolt to be connected, has simplified assembly technology, has improved efficiency of assembling.
As to improvement of the present utility model, lower shell body is hemispherical, and the first described filtrating equipment is hemispherical with lower shell body conformal.By lower shell body and the first filtrating equipment are arranged to hemispherical, make the first filtrating equipment when thering is enough filter areas, reduced whole size, and hemispheric the first filtrating equipment has higher storage ash ability, performance and the working life of having improved whole device.
As to restriction of the present utility model, the internal cavities of upper shell is rectangle.By upper shell, be set to rectangle, be convenient to the installation of the second filtrating equipment in upper shell, simplified overall structure.
As the improvement to aforesaid way, the double layer construction that the second described filtrating equipment consists of spaced the first filter plate and the second filter plate.By double-deck setting, effectively raise the filtering effect of the second filtrating equipment, strengthened the strainability of whole device.
As the improvement to aforesaid way, in upper shell, be fixed with the fixed plate that the second filtrating equipment is fixed.
As to restriction of the present utility model, described upper shell and lower shell body altogether medial axis arrange.By this, arrange, can make overall structure compacter, and be convenient to manufacturing.
As to improvement of the present utility model, described suction port and the non-coincidence setting of the center line of air outlet.By this, arrange, further changed the course of gas in air flue, improved filtering effect.
In sum, adopt the technical solution of the utility model, guaranteed that air filter for engines has good water-proof performance, effectively reduced whole volume, it is simple in structure.

Embodiment
The present embodiment relates to a kind of air filter for engines, as shown in Figure 1, it comprises the upper shell 1 of orthogonal structure and the lower shell body 2 that is arranged on upper shell 1 below, lower shell body 2 is hemisphere, it is connected on upper shell 1 by bolt is dismountable, in order to make overall structure compacter and be convenient to manufacture, upper shell 1 arranges medial axis altogether with lower shell body 2.
A side at upper shell 1 is provided with air outlet, is fixedly connected with steam outlet pipe 3 on this air outlet; On lower shell body 2, be provided with suction port, and on suction port, be fixedly connected with suction tude 4.In order to improve the filtering effect in air current flow process, the non-coincidence setting of center line of suction tude 4 and steam outlet pipe 3, in the present embodiment, suction tude 4 is along the oblique lower setting in medial axis of lower shell body 2, and vertical setting the in medial axis of steam outlet pipe 3 and upper shell 1.Upper shell 1 inside is the hollow cavity 101 of rectangle, the hemispherical cavity 201 that the inside of lower shell body 2 is hollow, and hollow cavity 101 and hemispherical cavity 201 are communicated with setting, and then form the air flue that is communicated with suction tude 4 and steam outlet pipe 3.In the bottom of lower shell body 2, be provided with drain opening 8.
As shown in Figure 2, in lower shell body 2, be provided with the first filtrating equipment 5 that the gas of the air flue of flowing through is filtered, and in upper shell 1, be provided with the second filtrating equipment 6 that the gas of the air flue of flowing through is filtered, the first filtrating equipment 5 and the second filtrating equipment 6 have been realized the filtration to the air-flow of the air flue of flowing through, and the two can all adopt existing filter core.In order to make the first filtrating equipment 5 there is larger filter area to reach better filter efficiency, in the present embodiment, the global shape of the first filtrating equipment 5 is spherical with the semicircle of lower shell body 2 conformals, and the spacing because of the two arranges formation cavity 7 between the first filtrating equipment 5 and lower shell body 2, this cavity 7 has formed entering into the buffering peptizaiton of the air-flow in hemispherical cavity 201, make gas can be full of whole cavity 7, to realize the utilization to the first filtrating equipment 5 maximum areas, simultaneously, also realized the ash of the storage to greatest extent effect of the dust that the first filtrating equipment 5 is filtered.
The second filtrating equipment 6 is fixedly installed in the hollow cavity 101 of upper shell 1, and arranges near steam outlet pipe 3, in order to realize, it is fixed, and is fixed with fixed plate 9, the second filtrating equipments 6 and is fixed on fixed plate 9 in hollow cavity 101.In order to realize the better secondary filter of gas, the second filtrating equipment 6 is the double layer construction along spaced the first filter plate 601 of upper shell 1 length direction and the second filter plate 602 formations, in addition, in order to realize better firm effect, with respect to the medial axis mirror image of upper shell 1, be provided with the 3rd filter plate 603 and the 4th filter plate 604 with the first filter plate 601 and the second filter plate 602, this is arranged so that whole " returning " character form structures that form of the second filtrating equipment 6.
In use, gas is entered in cavity 7 by suction tude 4, after the first filtrating equipment 5 filters, enters in hollow cavity 101, after the second filtrating equipment 6 filters, by steam outlet pipe 3, is discharged; When the interior water inlet of suction tude 4, can cause the impact on the first filtrating equipment 5, thereby make as much as possible the second filtrating equipment 6 avoid the invasion and attack of moisture, make it still there is good filtering effect, and the water entering in hemispherical cavity 201 finally can be discharged by drain opening 8.
