Referring to fig. 1-5, the present invention provides a technical solution:

the invention provides a combined type automobile air conditioner filter, which is provided with a top cover 1, a fixed sleeve 3 and a bottom cover 4 in order to protect the integrity of a filter element. The filter comprises a top cover 1 and a filter element 2 sleeved on the bottom surface of the top cover, wherein a fixed sleeve 3 is arranged on the outer side of the filter element 2, and a bottom cover 4 is sleeved on the bottom of the filter element 2. The edge of the bottom surface of the top cover 1 is provided with a plurality of guide posts 10 at equal intervals in an annular shape, so that the filter element 2 can be pressed. The middle section of the guide post 10 is provided with a convex ring 100, and the center of the bottom end of the guide post 10 is provided with a variable groove 101. The fixing sleeve 3 is in a circular ring structure, and the inner side surface of the fixing sleeve is in a ring shape and is provided with a plurality of clamping grooves 30 at equal intervals. A semi-circular table 31 is arranged on the outer side surface of the fixed sleeve 3 and at the position corresponding to the guide post 10. The center of the semi-circular table 31 is provided with a through hole 32 which is in inserted connection with the guide pillar 10. The top center of the bottom cover 4 is provided with an inner cavity 40 for sleeving the filter element 2. The top surface of bottom 4 just corresponds the department with the position of guide pillar 10 and has seted up shrinkage pool 41, and the bottom of guide pillar 10 is pegged graft with shrinkage pool 41 and is cooperated to top cap 1 and bottom 2 connect into wholly.

In this embodiment, the top cap 1, the fixing sleeve 3 and the bottom cap 4 are all made of PP material and are integrally formed, so that the top cap, the fixing sleeve and the bottom cap are light in weight, good in toughness and rigid in strength, and are durable.

Furthermore, the top cover 1 and the guide posts 10 are of an integrally formed structure, so that the integral installation is convenient.

Specifically, filter core 2 adopts a slice filter paper folding cylindrical ring structure that forms for filter effect is better under the equal space, and the top surface of filter core 2 does not contact top cap 1's bottom surface during the equipment, in order to leave top cap 1's activity space, when top cap 1 was pressed, can not press filter core 2 yet.

Specifically, the clamping groove 30 is matched with each bending part of the filter element 2 in a clamping mode, so that the distance between the folding parts of the filter element 2 is equal, and the filter is uniform.

In addition, the annular groove 320 has been seted up to the inboard interlude of through-hole 32, and annular groove 320 cooperates with bulge loop 100 joint for fixed cover 3 is spacing at the guide pillar 10 interlude, thereby makes 2 interlude distances of filter core even, because the lower extreme of filter core 2 cup joints and bonds with the inner chamber 40 at bottom 4 center, thereby the folding department interval of filter core 2 obtains keeping.

It should be added that the bottom surface of the concave hole 41 is provided with a tapered hole 42, the inner diameter of the bottom of the tapered hole 42 is smaller than the inner diameter of the top thereof, so that the bottom end of the guide pillar 10 is inserted into the tapered hole 42, the deformation groove 320 deforms to reduce the outer diameter, the guide pillar 10 further moves downwards, the bolt over-tightening force of the outer cover of the air conditioner filter is eliminated, and the filter element 2 is prevented from being folded.

The combined type automobile air-conditioning filter of the utility model is assembled, the fixed sleeve 3 is sleeved on the outer side of the filter element 2, the clamping grooves 30 are clamped into the bending part of the filter element 2 one by one, the lower end of the filter element 2 is sleeved in the inner cavity 40 of the bottom cover 4 and is bonded and fixed, the gap of the filter element 2 is uniformly distributed, and is beneficial to uniform filtration, meanwhile, the guide pillar 10 on the bottom surface of the top cover 1 passes through the through hole 32 of the fixed sleeve 3 and is spliced and matched with the concave hole 41 of the bottom cover 4, and the convex ring 100 is spliced and matched with the annular groove 320, so that the fixed sleeve 3 is stable and the middle section of the filter element 2, the filter element 2 is integrally placed into the sleeve of the air inlet pipe after the assembly is completed, and is fixed to the open end of the sleeve through the bolt air-conditioning filter outer cover, even if the bolt is screwed tightly, the top cover 1 is pushed to be, the integrity of the filter element 2 is protected.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
