Further, described air-inlet grille structure protrudes above what is be provided with for the periphery in the cylinder joint upper end
The flase floor of multi-disc uniform intervals arrangement.
Further, the multi-disc flase floor of the air-inlet grille structure is with the arranged for interval of small―gap suture, adjacent two frame
Gap between screen is inlet channel.
As a further improvement, the cylinder at the connecting portion of the cylinder joint protrudes above the screens provided with annular
Flange.
Improved as further, the cap is the housing of umbrella-shaped structure, and the inner chamber of the cap is from lower to upper
The multistage cavity become narrow gradually, the air-inlet grille structure are connected with the cavity wall of the cap.
Further, the cylinder joint is the structure of plastically deformable, and multiple equally distributed breach are by described in
Cylinder joint lower end is divided into multiple yielding arcs.
Beneficial effect
Compared with prior art, air filter rainhat of the present utility model has the beneficial effect that：
(1), design is simple, rational in infrastructure, Integration Design, using injection moulding integrated molding technique, whole air filter rainhat
An only part；
(2), anufacturability is good, and production efficiency is high；
(3), with coarse filtration function, it can effectively prevent sleet from entering inside air filter, use reliability is good, has very
Good application value.

In figure：1st, cap；2nd, cylinder joint；3rd, breach；4th, air-inlet grille structure；5th, screens flange.
Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not limited by embodiment.
Specific embodiment of the present utility model is such：As Figure 1-3, a kind of air filter rainhat, including cap
1, the axially inside extension of cap 1 is provided with the cylinder joint 2 with its gap arrangement, and the cylinder of the upper end of cylinder joint 2 is provided with
The air-inlet grille structure 4 being connected with cap 1, the lower end of cylinder joint 2 are provided with the connecting portion being connected with air filter, connect positioned at cylinder
Cylinder lower end opening at first 2 connecting portion is simultaneously axially extending provided with multiple breach arranged along its periphery uniform intervals
3, the connecting portion of cylinder joint 2 is connected with air filter, due to setting jagged 3 on the cylinder at connecting portion, is easy to connecting portion
The cylinder at place opens to be connected with cleaner, accelerates grafting speed, and front band can be covered at the connecting portion of cylinder joint 2,
Cylinder at the connecting portion of cylinder joint 2 is compressed and is allowed to deform, so as to ensure that cylinder joint 2 is connected jail with cleaner
Gu connection is tight；The upper end open of cylinder joint 2, it is connected by air-inlet grille structure 4 and the top of cap 1, air inlet
Covered by cap 1, be not easily accessible sleet dust, played a part of to the preliminary filtering of air, and good filtration effect.
In the present embodiment, air-inlet grille structure 4 protrudes above the multi-disc being provided with for the periphery in the upper end of cylinder joint 2
The flase floor of uniform intervals arrangement, makes multi-point support between cylinder joint 2 and cap 1, is connected firmly, and ensures air filter rainhat matter
Amount, using reliable.
In the present embodiment, the multi-disc flase floor of air-inlet grille structure 4 is with the arranged for interval of small―gap suture, adjacent two panels grid
Gap between plate is inlet channel, and grid gap is small, inlet channel is had coarse filtration function, and dust, sleet etc. are stopped
Effect is good.
