As the improvement of technique scheme, the end face of said long slab is provided with short slab, and said short slab and said transverse slat butt can reduce the height of long slab intermediate sector, abdicate cavity intermediate portion space, stretches out one's hand easily to get into cleaning dust in the cavity;

Further, said baffle plate extends to form the handle long slab up and down, is convenient to the installation and removal of filter core;

Further, described handle long slab and transverse slat link together, and are convenient to the convenience of manufacturing, gain in strength.

The invention has the beneficial effects as follows: the track that uses the long slab conduct to match with the filter core support, further limit the rigging position of filter core support through transverse slat, make the rigging position of filter core and filter core support unique, cooperate reliable and stablely, guaranteed filtering effect; Use length to harden and close the location, when taking out the filter core support, the accent position has formed bigger space, can stretch out one's hand easily to get into cleaning dust in the cavity; Process simple and conveniently, reliable in structure is practical, safeguards easily.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the generalized section of installment state of the present invention;

Fig. 3 is the structural representation of another embodiment of the present invention.

Embodiment

See figures.1.and.2; A kind of air-strainer of the present invention comprises cavity 1, is inserted into the filter core support 2 in the cavity 1; And be fixed on the filter core 3 in the filter core support 2; With the lid 4 that covers cavity 2 openings, the last inwall 5 and the following inwall 6 of said cavity 1 are provided with the fixed groove 8 that is formed by two long slabs 7, in the fixed groove 8 under said filter core support 2 is installed on; Top and the bottom, said filter core support 2 side are provided with the end face 9 of butt long slab 7 respectively; The transverse slat 10 that restriction filter core support 2 moves up and down, the side 11 of said support 2 also are provided with the baffle plate 13 of the exterior edge face 12 of butt long slab 7, restriction filter core support 2 forward direction motion, the outer side surface 14 of the said filter core support 2 of said lid 4 butts.

In order to limit the move left and right of filter core support 2, the end face of said long slab 7 is provided with short slab 15, said short slab 15 and said transverse slat 10 butts.

For the ease of removing and installing, said baffle plate 13 extends to form handle long slab 16 up and down.

Further, described handle long slab 16 links together with transverse slat 10.

In this embodiment, when filter core 3 when 2 combinations are inserted in the cavitys 1 with the filter core support, closely cooperate with long slab 7 in the cavity 1, guarantee that with being separated into clean chamber and exocoel in the cavity 1 long slab 7 has limited the move left and right that filter core 3 and filter core support 2 make up; Two transverse slats 10 on the filter core support 2 cooperate the location with the short slab 15 that two group leader's plates, 7 outer ends are provided with simultaneously, have limited moving up and down of
