Referring to figs. 1 through Fig. 6, efficient air filter 100 described in the utility model, comprises housing 10, filter core 20, admission piece 30 and sound damper 40.

Wherein, housing 10 is preferably cylinder shape, it is possible to hold filter core 20, it is also possible to be other shapes, inner hollow, such as, can be trilateral, the shape such as square. Also it is provided with a sewage draining exit 11 on the housing 10, for being connected with filter core 20, the foreign material of filter core 20 filtering and moisture etc. is discharged.

Having offered inlet mouth 12 and air outlet on the housing 10, air is entered in housing 10 by inlet mouth 12, flows out by air outlet. The cross section of admission piece 30 is for circle and has entrance end 31 and exit end 32, and the exit end 32 of admission piece 30 is connected with the inlet mouth 12 on housing 10. The cross-sectional diameter of admission piece 30 is increased by entrance end 31 to exit end 32, and namely admission piece 30 has diameter change so that its structure is that one end is big, and one end is little, and in the present embodiment, entrance end 31 diameter of admission piece 30 is greater than exit end 32 diameter 2mm-5mm. This structure can control to enter the air flow quantity of admission piece 30, increases and enters the air flow quantity in housing 10 by admission piece 30. The exit end 32 of admission piece 30 is provided with two relative latches 34 of position, latch 34 is provided with relative two elastic bumps portion 35, it is provided with relative two connector assembly 15 close to inlet mouth 14 place accordingly at housing 10 inwall, namely connector assembly 15 is all set on the inwall of inlet mouth 14 both sides, is respectively used to connect with two latch 34 phase cards on admission piece 30. Connector assembly 15 is provided with the jack 16 coordinated with latch 34, and latch 34 is located in this jack 16, to connect admission piece 30 and housing 10. When latch 34 is inserted in jack 16, being stuck in jack 16 by elastic bumps portion 35, admission piece 30 can not drop easily from housing 10. And when needs take out admission piece 30, elastic bumps portion 35 pressed by craft or use instrument, latch 34 can be extracted out in jack 16. Latch 34 and connector assembly 15 by mechanically resistant material making case such as the material such as highstrenghtpiston, metal. The setting of admission piece 30, reduces air to the surging force in housing 10, prevents filter core to be out of shape under air-generated impact.

Sound damper 40 is connected with the entrance end 31 of admission piece 30. Sound damper 30 surface has the rib 36 in shape of threads, and sound damper 40 one end has the card being made up of resilient material and buckles 41, is provided with card groove 37 accordingly on admission piece 30, and card button 41 is located in card groove 37, with joint noise reduction device 40 and admission piece 30. In the present embodiment, the both sides of sound damper 30 respectively arrange a card and buckle 41, are respectively provided with a card groove 37 accordingly in the both sides of admission piece 30. Card button 41 is fastened in card groove 37, with joint noise reduction device 40 and admission piece 30. It is equipped with some loading plates 50 in admission piece 30 and sound damper 40, the two ends of loading plate 50 are connected with the inwall of admission piece 30 or sound damper 40 respectively, namely the two ends of the loading plate 50 in admission piece 30 are connected with the inwall of admission piece 30, the two ends of the loading plate 50 in sound damper 40 respectively inwall with sound damper 40 be connected. Loading plate 50 hollow out and setting of mutually staggering, to ensure that air can be independent of each other through loading plate 50 and loading plate 50. Being provided with absorption charcoal bag 51 on loading plate 50, absorption charcoal bag 51 can adsorb to fall a part of objectionable impurities in air. Fig. 3 shows the structure of the loading plate 50 in admission piece 30, and loading plate 50 structure in sound damper 40 is identical, not shown in the drawings with loading plate 50 structure in admission piece 30.

Inlet mouth 12 place of housing 20 is provided with some dust suction sheets 121, and the two ends of dust suction sheet 121 are connected with housing 10 respectively, and dust suction sheet 121 is obliquely installed in predetermined angle, and forms air intlet between adjacent dust suction sheet 121.This dust suction sheet 121 is made up of the material of advantages of good adsorption effect such as trevira. Absorption charcoal bag 51 can adsorb to fall a part of objectionable impurities in air, and then air inhales dust by being located at the dust suction sheet 121 of inlet mouth 12 again, thus the Air quality entered in housing 10 improves greatly.

Filter core 20 sealing is arranged in housing 10, for being filtered by the foreign material in air, is the core parts of this strainer 100. It is preferably tubular, forms filter core cylinder, in its hollow parts being contained in housing 10. The center of filter core 20 is provided with center bearing bracket 60, and center bearing bracket 60 is made up of plastic material, and in tubular, it is preferable to identical with the shape of filter core 20, it is cylinder shape. The sidewall hollow out of center bearing bracket 60 is arranged or the sidewall of center bearing bracket 60 is provided with multiple hole, the outer wall of center bearing bracket 60 is provided with the step 61 of spirrillum, step 61 fits tightly with the inwall of filter core 20, hole on center bearing bracket 60 is not contacted with the filter screen hole of filter core 20, enables air fully in filter core 20 internal flow.

The above embodiment only have expressed several enforcement mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model patent scope. , it is also possible to make some distortion and improvement, it should be appreciated that for the person of ordinary skill of the art, without departing from the concept of the premise utility these all belong to protection domain of the present utility model. Therefore, the protection domain of the utility model patent should be as the criterion with claims.
