the front end of the connecting sleeve is connected with the air inlet piece in a sealing way, and the rear end of the connecting sleeve is connected with the air outlet piece in a sealing way; and
the primary filter element is arranged in the connecting sleeve.
For providing the filter fineness, the piece of giving vent to anger in be equipped with the second grade filter core, the filter fineness of this second grade filter core is greater than the filter fineness of one-level filter core.
Consider the convenient change of one-level filter core, connecting sleeve include the body and can open and close the apron of being connected with the body.
Preferably, the air inlet part comprises
The water inlet structure comprises a seat body, a plurality of air inlet sleeves are convexly arranged on the inner side of the front end surface of the seat body, an air inlet is formed on the outer side of the front end of each air inlet sleeve, a spiral fan blade is embedded in each air inlet sleeve, and the bottom of the seat body forms the water outlet; and
the lining piece comprises a bottom plate and a plurality of hollow connecting pipes which are convexly arranged on the bottom plate, the bottom of the lining piece is hermetically assembled on the seat body, and the front ends of the connecting pipes extend into the rear end of the air inlet sleeve and leave drainage gaps with the inner wall of the air inlet sleeve.
Preferably, the helical fan blade comprises a central shaft and at least two helical blades arranged around the central shaft.
Furthermore, the rear end of the connecting pipe is in a flared horn shape, so that the air flow can rapidly enter the first-stage filter element.
Compared with the prior art, the utility model has the advantages of: air enters from the air inlet, is guided by the spiral fan blades to form cyclone, water vapor is thrown out, is discharged from the water outlet after being accumulated, and air continues to advance and is discharged from the air outlet after being filtered by the primary filter element, so most of water vapor and dust are firstly filtered, and most of particles and dust are filtered in the primary filter element.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1 and 2, the air filter in the present embodiment includes an air inlet 1, an air outlet 3, a connection sleeve 2, a primary filter element 41, and a secondary filter element 42.
The front end of the air inlet part 1 is provided with a plurality of air inlets 111 which are arranged side by side, and each air inlet 111 is internally provided with a spiral fan blade 13 which can lead the air inlet to be spirally guided; the lower end of the air inlet part 1 is provided with a water outlet 112; the air outlet member 3 has an air outlet 31.
The front end of the connecting sleeve 2 is hermetically connected with the air inlet part 1, and the rear end of the connecting sleeve is hermetically connected with the air outlet part 3; the connecting sleeve 2 in this embodiment includes a body 21 and a cover plate 22 capable of being opened and closed with the body 21, so as to facilitate replacement of the first-stage filter element 41.
The primary filter element 41 is disposed within the adapter sleeve 2. The second grade filter core 42 is arranged in the air outlet part 3, and the filtering precision of the second grade filter core 42 is larger than that of the first grade filter core 41.
As shown in fig. 3, 4 and 5, the air intake component 1 in this embodiment includes a base 11 and a lining 12, a plurality of air intake sleeves 113 are convexly disposed on the inner side of the front end surface of the base 11, an air inlet 111 is formed on the outer side of the front end of each air intake sleeve 113, a spiral fan blade 13 is embedded in each air intake sleeve 113, and a water outlet 112 is formed at the bottom of the base 11; the lining member 12 includes a bottom plate 121 and a plurality of hollow connecting pipes 122 protruding from the bottom plate 121, the bottom of the connecting pipes is hermetically mounted on the seat body 11, and the front ends of the connecting pipes 122 extend into the rear end of the air inlet sleeve 113 and leave a drainage gap 1a with the inner wall of the air inlet sleeve 113.
