Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," in an embodiment of the present invention should not be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
Referring to fig. 1 to 3, an embodiment of the present invention provides a filter screen 10 for an air purifier, where the filter screen 10 includes:
an annular housing 11;
a filter screen body (not shown) disposed inside the annular housing 11;
a plurality of baffles 12 disposed inside the annular housing 11 and evenly distributed around the center of the annular housing 11;
the baffle is curved and has an oblique angle with the horizontal, angle α in fig. 3.
The outer and inner contour shapes of the annular housing 11 shown in fig. 1 are circular, which facilitates the processing of the annular housing 11 and facilitates the assembly of the annular housing 11 on the air cleaner.
It will be appreciated that the shape of the annular housing 11 may take other shapes, for example: the outer contour of the annular shell 11 is rectangular, and the inner contour is circular; or the outer contour of the annular housing 11 is circular and the inner contour is rectangular. The person skilled in the art can adjust the shape of annular casing 11 according to the interior spatial structure of actual air purifier, and the embodiment of the present invention is not specifically limited to the shape of annular casing 11.
Above-mentioned filter screen body is used for treating air-purifying and carries out prefilter to the great filth of filtering scraps of paper, large granule dust isovolumn. It should be noted that, for showing clearly, the concrete structure of filter screen body is not shown in the figure, and this filter screen body can adopt current filter screen body to realize, the embodiment of the utility model provides a do not restrict the concrete structure of filter screen body.
The guide plate 13 is disposed inside the annular housing 11 to guide the gas flowing in. It can be understood that the arrangement sequence of the filter screen body and the guide plate 13 is not limited when the filter screen body and the guide plate 13 are arranged, so that air firstly passes through the filter screen body and then passes through the guide plate 13, or firstly passes through the guide plate 13 and then passes through the filter screen body.
The baffles 13 are evenly distributed around the centre of the annular housing 11; by uniformly distributing the guide plates 13, the flow guide effect on the airflow flowing into each area in the annular shell 11 is basically consistent, and the stability of the airflow is improved.
Fig. 1 to 3 show a scenario in which 8 baffles 13 are arranged in an annular housing 11. It should be noted that the number of baffles 13 may also be other numbers, such as: 5, 6, 7 etc. the embodiment of the utility model provides a do not specifically limit to the quantity of guide plate 13.
The baffle 13 is curved and has an inclination angle with the horizontal plane, so that the air current changes the flow direction under the action of the curved inclined plane when passing through the baffle 13, and flows in a vortex manner.
In some embodiments, the shape of the baffles 13 is circular arc, the bending radius of each baffle 13 is the same, and the inclination angle between each baffle 13 and the horizontal plane is the same, so that the flow guiding effect of the airflow flowing into each area in the annular housing 11 can be kept consistent.
It should be noted that when the bending direction of the baffle 13 is set, an environmental factor applied to the air cleaner is considered, specifically, the environmental factor is a local turning force direction, and the turning force affects the swirling flow of the fluid, so that when the gas is guided, the guiding direction needs to be matched with the turning force direction.
Specifically, when the use area of the air purifier is the northern hemisphere, each baffle 13 is bent in the counterclockwise direction along the gas flow direction, i.e., the scene shown in fig. 1; when the use area of the air purifier is the southern hemisphere, each guide plate 13 is bent in a clockwise direction along the gas flow direction. Therefore, the influence of the deflection force on the flow of the air flow can be avoided, and the smooth flow of the air is ensured.
Referring to fig. 3, the angle of inclination between the baffle 13 and the horizontal plane, that is, the angle α, is any angle from 45 ° to 87 °, and this angle range can be used to obtain a better wind noise reduction effect and air purification efficiency for the air purifier.
In some embodiments, the height h of the deflector 13 is not greater than 5 mm, and the size of the filter screen 10 is reduced while the gas guiding effect is ensured by limiting the size of the deflector 13.
The embodiment of the utility model provides an in, set up in air purifier's filter screen and have inclination's guide plate between the horizontal plane, each guide plate centers on the annular shell center evenly distributed of filter screen, carries out the water conservancy diversion to the air current that flows into air purifier through the guide plate, makes the air current flow in with the mode of swirl, reduces the turbulent flow, reduces air purifier's wind and makes an uproar, and swirl air current flows steadily simultaneously, can improve air purification efficiency.
The embodiment of the utility model also provides an air purifier, which comprises an air inlet and the filter screen, wherein the filter screen is arranged at the air inlet;
the embodiment of the utility model provides an in, the air flows in by air purifier's air intake, through the guide plate water conservancy diversion of filter screen to the mode of swirl flows, reduces the turbulent flow, reduces air purifier's wind and makes an uproar, and the swirl air current flows steadily simultaneously, can improve air purification efficiency.
In some embodiments, referring to fig. 4 and 5, the air purifier further comprises: the equipment end cover 20 is detachably arranged at the air inlet and is connected with the air inlet through a buckle for example;
the equipment end cover 20 is annular, and the filter screen 10 is positioned on the inner side of the equipment end cover;
a first boss 111 is arranged on the outer side of the annular shell 11 of the filter screen 10;
a second boss 21 and a plurality of limiting bolts 22 are arranged on the inner side of the equipment end cover 20;
the first boss 21 is sandwiched between the second boss 21 and a plurality of limit bolts 22, and the limit bolts 22 may be existing limit bolts, for example: hexagon socket head cap screw because spacing bolt 22 is located the inboard of equipment end cover 20, uses hexagon socket head cap screw to realize spacing fixed, can directly use hexagon socket head cap screw simultaneously when dismantling, saves bolt assembly space.
