The purpose of this utility model is to reduce spiral board adverse effect that suction pressure is caused, provides that a kind of suction pressure is less, the air-strainer of dust discharge better effects if.

For achieving the above object, embodiment of the present utility model provides following technological scheme:

A kind of air-strainer, comprise housing, be arranged on suction tude and steam outlet pipe on described housing, described suction tude is tangential admission pipe, is provided with multiple spinning disks near the opening of described the above suction tude of inner walls, and each described spinning disk is spaced apart along the axial and circumferential of described housing.

Preferably, above-mentioned air-strainer also comprises dust discharge chamber, and described housing below is provided with dust exhaust port, and described dust exhaust port place is provided with buckle structure, and described dust discharge chamber is fastened on described dust exhaust port place by described buckle structure.

Preferably, in described steam outlet pipe, be provided with mesh grille.

Preferably, on described housing, be provided with wire harness draw-in groove.

Preferably, described housing is divided into upper shell and lower shell body, and described steam outlet pipe is arranged on described upper shell, and described suction tude is arranged on described lower shell body.

Preferably, described dust exhaust port is arranged on the position away from described spinning disk.

The utility model is arranged as multiple spinning disks at the axial and circumferential interval of simultaneously stating housing, but not only along circumferential arrangement, in other words, in the axial direction, spinning disk from the opening of suction tude more and more away from, can not hinder air inlet, therefore, in having ensured eddy flow effect, ensure the low suction pressure of tangential admission.

Further, the utility model adopts independently dust discharge chamber to be fastened on dust exhaust port place, and storage is grey, drainage capacity is stronger, prevents that Inlet Swirl from driving the floating of dust and water to flow, and facilitates periodic cleaning.

Further, the mesh grille in steam outlet pipe is beneficial to out stable, the parallelization of airflow field.

Description of symbols in upper figure: end cap 1, filter core 2, semicircle housing 3, spinning disk 4, tangential admission mouth 5, end cap 6, air outlet 7, semicircle housing 8, positive stop lug boss 9, rotating shaft 10, connect boss 11 dust exhaust ports 12, dust discharge valve 13, suction tude 14, housing 15, steam outlet pipe 16, upper shell 17, wire harness draw-in groove 18, lower shell body 19, the first spinning disk 20, the second spinning disk 21, the 3rd spinning disk 22, the 4th spinning disk 23, opening 24, dust discharge chamber 25, buckle structure 26, dust exhaust port 27, grid 28.

Embodiment

With reference to figure 4, the air-strainer of the present embodiment comprises housing 15, is arranged on suction tude 14 and steam outlet pipe 16 on housing 15.The interior filter core (unmarked) that arranges of housing 15, air through suction tude 14 enter housing 15 interior after, through filter element filtering, discharged by steam outlet pipe 16.

In conjunction with Fig. 5, Fig. 6, visible the present embodiment middle shell 15 is divided into upper shell 17 and lower shell body 19, and certainly, the utility model is not got rid of the structure that adopts two semicircle housings in Fig. 1.Steam outlet pipe 19 is arranged on upper shell 17, and on upper shell 17, is also provided with wire harness draw-in groove 18 for fixed beam.More high-visible from Fig. 6, suction tude 14 is arranged on lower shell body 19, is tangential admission pipe, and the axis of suction tude 14 does not point to lower shell body 19 center, but is parallel to a diameter of lower shell body 19.

In conjunction with Fig. 6, Fig. 7, visible on lower shell body 19 inwalls, opening 24 positions near suction tude 14 are provided with multiple spinning disks, comprise the first spinning disk 20, the second spinning disk 21, the 3rd spinning disk 22 and the 4th spinning disk 23, and between these spinning disks 20,21,22,23, be not a circumferential wr interval along arrow indication, but simultaneously spaced apart along the axial wa of arrow indication and the circumferential wr of arrow indication of lower shell body 19.That is to say, leaving mouthful 24 two nearest spinning disks is the second spinning disk 21 and the 3rd spinning disk 22, and the first spinning disk 20 and the 4th spinning disk 23 in circumferential wr direction away from opening 24, and the first spinning disk 20 and the 4th spinning disk 23 in axial wa direction also away from opening 24, like this, these spinning disks are not on the same annulus concentrating in circumferential direction, reduce the obstruction of the air inlet to opening 24, therefore in having ensured eddy flow effect, ensured the low suction pressure of tangential admission.

In conjunction with Fig. 7, Fig. 8 and Fig. 9, there is in the present embodiment independent dust discharge chamber 25, below lower shell body 19, be provided with dust exhaust port 27, at dust exhaust port, 27 places are provided with buckle structure 26, and dust discharge chamber 25 is fastened on dust exhaust port 27 places by buckle structure 26.And, dust discharge chamber 25 is arranged on the position away from four spinning disks 20,21,22,23, be that dust exhaust port 27 is arranged on the position away from spinning disk 20,21,22,23, can ensure like this after the abundant eddy flow of air that dust and water are pooled in dust discharge chamber 25, dust discharge better effects if.And independently dust discharge chamber 25 can prevent that Inlet Swirl from driving the floating of dust and water to flow, and facilitates periodic cleaning.

With reference to Figure 10, in steam outlet pipe 16, be provided with mesh grille 28, be conducive to stable, the parallelization of airflow field.

Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and be only subject to the restriction of claim, those of ordinary skill in the art can easily modify to it and change, but do not leave essence design of the present utility model and scope.
