Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, high efficiency particle air filter of the present invention is described in further detail:
As in Figure 2-4, high efficiency particle air filter 20 of the present invention is a box body structure, and described box body is divided into two parts: the sidewall on front panel 21 and formation limit, the same side four; Squab panel 25, and the sidewall being formed in limit, the same side four regularly, the interior volume that four sidewalls that four sidewalls on described squab panel 25 snapably can just insert front panel 21 limit to.Being formed with air inlet 24 at the central upper portion place of front panel, to make air-flow enter high efficiency particle air filter inside, wallboard 25 being thereafter provided with multiple steam vent 28, entering motor cavity to make the clean gas through filtering.Wherein, the inside cavity of box body is provided with porous filter material 23, be generally sponge, in order to implement to filter to air-flow, for strengthening the guiding to air inlet 24 place air-flow, between front panel 21 and filtering material 23, be provided with water conservancy diversion orifice plate 30, described water conservancy diversion orifice plate 30 is hard sheet structure, and generally its thickness is at the 2mm of left and right.
Described water conservancy diversion orifice plate 30 is provided with through manhole 31, when air-flow enters from air inlet 24, impact on water conservancy diversion orifice plate 30, fraction enters in filtering material 23 from the through hole corresponding to air inlet 24 place through water conservancy diversion orifice plate 30, and all the other air-flows are passed water conservancy diversion orifice plate to enter filtering material by the through hole disperseed through other positions.For ensureing that air-flow is disperseed the unimpeded of rear flowing, the inside sidewalls of described front panel is provided with position limiting structure, and it makes water conservancy diversion orifice plate 30 and front panel 21 inner surface arrange to interval, ensures that remaining with certain narrow chamber is between the two beneficial to air current flow.
Further, for improving the dispersion effect of air-flow, alleviate the filtration burden at corresponding air inlet place, the through-hole aperture of described water conservancy diversion orifice plate from top mutually under progressively increase, the through-hole diameter namely corresponding to the water conservancy diversion orifice plate at air inlet place is less, and its diameter is at about 2mm, and more down aperture is larger, progressively increase to about 15mm, this provides for improved the dispersion effect to air-flow, avoid producing larger damping simultaneously.The aperture of certainly described through hole increases mode and radiant type centered by corresponding air inlet place can also be taked progressively to increase symmetrically.
Further, water conservancy diversion orifice plate corresponds to front panel side and is formed with water conservancy diversion rib, described water conservancy diversion rib vertically interval is arranged to guide air-flow to flow downwards or upwards, prevents turbulent flow.Certainly described water conservancy diversion rib set-up mode is not limited to downward-extension, and centered by corresponding air inlet place, radiant type stretches out the effect arranging and can play equally and guide air-flow.
In addition, arrange water conservancy diversion orifice plate and its relative front panel is tilted, the distance namely between water conservancy diversion orifice plate and front panel progressively increases from top to bottom, is more conducive to air-flow like this and flows downward, and realizes the object of the present invention.
