Detailed Description

In order to make the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below with reference to the accompanying drawings and examples.

The first embodiment is as follows:

as shown in fig. 1-4, a filtering structure of an air handler includes a handler body 1, an air duct 11 is provided in the handler body 1, a mounting opening 12 communicated with the air duct 11 is provided on a side surface of the handler body 1, and a filter is provided in the air duct 11;

the filter comprises a plate body 2, a filter plate 21, a push-pull plate 22 and two sealing components, wherein the push-pull plate 22 is connected with the plate body 2 and matched with the mounting port 12, a through groove 23 is formed in one side, away from the push-pull plate 22, of the plate body 2, the filter plate 21 is in threaded connection with the inner wall of the through groove 23, and the two sealing components are respectively arranged at the upper end and the lower end of the plate body 2 and matched with the through groove 23;

seal assembly includes a movable ring 3 and a plurality of compensation spring 31, ring groove 32 is all opened at both ends about the plate body 2T-shaped, ring groove 32 is evenly encircled to a plurality of compensation spring 31, movable ring 3 slide locate ring groove 32T-shaped and with a plurality of compensation spring 31 butt, the perpendicular section structure of movable ring 3 is T shape and right angle limit and is located ring groove 32T-shaped, the last lower limb of installing port 12 is the inclined plane, and 11 interior symmetries in wind channel are equipped with seal assembly assorted binding plate 33.

Under the condition of normal use, the filter is arranged in the air duct 11, wherein the filter plate 21 can filter the air in the air duct 11, and in order to avoid poor filtering effect caused by the fact that the air passes through the gap between the filter and the processor body 1, at the moment, the sealing assembly can play a role of actively compensating the gap, under the static state, as the whole plate body 2 is arranged in the air duct 11, the sealing assembly is blocked and extruded by the processor body 1 at the moment, the compensation spring 31 is always kept in the stretching state in the process, and then the movable ring 3 is actively pushed to extend out of the corresponding T-shaped annular groove 32, so that the movable ring 3 is actively attached to the attaching plate 33 on the corresponding side, and thus the active sealing effect is played, and therefore, the air can be forced to pass through the filter plate 21, meanwhile, the two integrally annular sealing assemblies can more effectively provide good sealing effect for the filter, especially, after the filter is dismounted for many times or used for a long time, when a large aging friction loss gap or a gap occurs between parts, the sealing assembly can be actively compensated, and a more effective sealing effect is further played;

when needs clear up or change the filter 21, only need through pulling push-and-pull plate 22, make whole filter take out from processor organism 1, because threaded connection between filter 21 and the logical groove 23 of plate body 2, consequently only need rotate the filter 21 when dismantling filter 21 until screwing out can, with the clearance clear up or change accomplish the back, through same mode with plate body 2 back dress processor organism 1 can, under quiescent condition, because frictional force between the part and seal assembly's initiative butt effect, whole filter can be relatively stable install in processor organism 1, difficult automatic roll-off, also can convenient and fast's operation when later stage dismantlement, satisfy the user demand, the upper and lower limit of installing port 12 is the setting on inclined plane, can be when installing plate body 2 gets into wind channel 11, play the effect of pressing activity ring 3, avoid taking place blockking of part between activity ring 3 and the installing port 12 and cause the installation inconvenience.

The upper end of the filter plate 21 is symmetrically provided with convex rods 211; the provision of the protruding bars 211 can facilitate the rotation of the filter plate 21.

One end of the movable ring 3 extending out of the T-shaped ring groove 32 is provided with a sealing ring 301 matched with the jointing plate 33; the provision of the seal ring 301 can further improve the sealing effect between the movable ring 3 and the attachment plate 33.

Example two:

as shown in fig. 5-7, based on the first embodiment, the first embodiment is further improved, the push-pull plate 22 is symmetrically provided with stoppers in the left and right directions, each stopper includes a stopper plate 4, a connecting rod 41, a lock tongue 42, a return spring 43 and a pulling block 44, the left and right sides of the push-pull plate 22 are symmetrically provided with two step cavities 45, the stopper plates 4 are slidably disposed in the step cavities 45, the left and right sides of the installation opening 12 are both provided with a stopper groove 46, the lock tongue 42 is connected with the stopper plate 4 and is close to the stopper groove 46 on the same side, the connecting rod 41 is fixedly disposed at the other end of the stopper plate 4, the left and right sides of the push-pull plate 22 are oppositely provided with a movable groove 47, the connecting rod 41 slidably extends into the movable groove 47, the pulling block 44 is slidably disposed in the movable groove 47 and is fixedly connected with the connecting rod 41, and the return spring 43 is sleeved on the connecting rod 41 and is disposed in the step cavities 45; the pulling block 44 is in the shape of a hollow ring, and the push-pull plate 22 is provided with a stress block 48 matched with the pulling block 44.

After the whole filter is installed, the installation stability of the filter can be further improved through the limiting stopper, the filter is directly limited and prevented from being disconnected, when the push-pull plate 22 is installed and enters the installation opening 12, the lock tongue 42 is blocked by the processor body 1 and gradually retracts into the step cavity 45 until the push-pull plate 22 continuously moves until the lock tongue 42 corresponds to the limiting groove 46, the limiting plate 4 is pushed to move through the resetting elasticity of the resetting spring 43, the lock tongue 42 extends out and is clamped into the limiting groove 46, and the position of the whole push-pull plate 22 is limited at the moment, so that the filter cannot automatically slide out, and the stability is further improved;

and when needing to take out the filter, only need both hands to detain pulling piece 44 through the forefinger simultaneously, because pulling piece 44 is hollow cyclic annular, consequently can be convenient for more detain and move, cooperation thumb butt atress piece 48 stimulates, in the spring bolt 42 is withdrawed step chamber 45 by the initiative this moment, pull out the filter outward at last can, easy dismounting is swift like this, can effectively improve the stability after the filter installation, avoids the automatic roll-off of filter to influence the filter effect.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention.
