Abstract

The utility model relates to an air filter, which is composed of a casing, two net sheets and a fixing ring set. In a casing (1), mutually crossed partition boards (4) divide the casing (1) into a plurality of filter chambers (5) in deltate shape or tetragonal shape or regular hex shape. Filter mediums (6) are positioned on the inner side of the filter chambers (5). The two sides of the casing (1) are respectively provided with a fixed ring (3) making the net sheets closely pasted on the side of the casing (1). The filter medium (6) can be activated charcoal, or other porous absorption materials. The device is arranged on the air outlet of a fan, smoke or oil smoke or other dust in air are uniformly be absorbed and the air is purified.

Description

Air filter

The utility model relates to a kind of filter of filter housing structure, and relates more specifically to a kind of air filter.

In background technology, fan can only circulate the air in its place site space, but can not reach the effect of filtration, purification air, particularly after indoor air is by the pollution of the oil smoke of the smog of cigarette, cooking generation or other dust or dust, though fan can make indoor air alleviate the concentration of its pollution in the process of circulation, but it just reduces concentration in its unit space by diffusion way, not being to be the method for thoroughly effecting a radical cure, is to allow environment in larger scope be subjected to pollution on the contrary.

Primary and foremost purpose of the present utility model is to be to design a kind of air filter that can carry out filtration, purification to the air that fan blows out.Another purpose of the present utility model is to be to design a kind of air filter that reduces number of spare parts and compact conformation as far as possible.

The utility model is realized by following design: in a housing that is installed in fan, be divided into several by cross one another dividing plate and be equilateral triangle, or quadrangle, or the filter chamber of regular hexagon and other shape, to be used for placing filter medium with adsorption capacity.In the both sides of housing, then be respectively equipped with the net sheet, and it be close on the side of housing, to prevent the loss of filter medium by retainer ring.At last said apparatus is located on the fan, can be reached predetermined purpose.

Effect of the present utility model is tangible, because the centre of housing is divided into a plurality of filter chambers like the honeycomb by dividing plate, the filter medium that makes in the device to be put can only not be to be deposited on lower part of frame, and can be distributed in the entire cross section of housing more equably, thereby impel the filtration that can both obtain filter medium by the air of this device.As adopted air filter described in the utility model, in view of the wind that fan blew out, be just to enter the space through after the filtration of air filter described in the utility model earlier, former airborne smog or oil smoke or dust and dust, the filter medium that then is placed in the filter chamber is adsorbed, thereby the air that blows out then is to be filtered the fresh air that purified.As the utility model being used for occasions such as range hood, ventilating fan, the effect of can play absorption equally, filtering and purifying helps environmental protection.In a word, behind employing the utility model, can realize the described expected effect of this specification.

Below in conjunction with accompanying drawing embodiment of the present utility model is described, thereby make CONSTRUCTED SPECIFICATION of the present utility model, characteristics, purpose and advantage clearer and more definite.

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is the structural representation of described housing.

Fig. 3 is a structural representation of implementing conversion example middle shell.

Among the figure: 1-housing, 2-net sheet, 3-retainer ring, 4-dividing plate, 5-filter chamber, 6-filter medium

The structure of the utility model embodiment now is described in conjunction with the accompanying drawings:

As shown in Figure 1, the described a kind of air filter of present embodiment is by comprising what housing 1, two networking sheets 2 and retainer ring 3 were formed.In described housing 1, shown in accompanying

drawing

2,3, by cross one another dividing plate 4 housing is divided into several and is equilateral triangle, or quadrangle, or the filter chamber 5 of regular hexagon and other shape, in filter chamber 5, then lay filter medium 6.Should there be abundant number described filter chamber 5, so that the described filter medium 6 that is put in the filter chamber 5 can be distributed in the entire cross section of housing 1 equably, rather than only is deposited on the bottom of housing 1.In the both sides of housing 1, be respectively arranged with described net sheet 2, and it be close to the place, side of housing 1, to prevent the outflow of filter chamber's 5 interior filter mediums of being laid 6 by described retainer ring 3.In the present embodiment, described filter medium 6 can be activated carbon or other porous sorptive material.When device being located at commercially available blade-rotating electric fan; on the shell of blade-rotating one side as it; the wind that then described electric fan blows out; all will be at first by equally distributed filter medium 6 in the described device of present embodiment; and by its filtration, purification; this moment former suction air in contained various impurity; as smog or oil smoke or impurity such as other dust and dust; can be filtered all that medium 6 is adsorbed to be fallen; thereby through the clean air that present embodiment blew out after will being to purify, it helps the health of human body and the protection of environment.

In order to reduce number of spare parts and to make for the purpose of the compact conformation of device, as shown in Figure 3, a kind of conversion example as present embodiment, a net sheet 2 and described housing 1 can be closed and make one, also can save a retainer ring this moment, both reduced the quantity of part, also reduced assembly work, convenient especially use.When using this enforcement conversion example, the net sheet of a side need not be installed in advance again, only need directly filter medium 6 to be positioned in the filter chamber 5, only need the net sheet 2 of encapsulation opposite side just to finish whole device then, and can be for selecting for use.

The utility model can be loaded on the devices such as all kinds of fans, ventilation fan, exhaust fan or range hood, sells in the lump with complete machine, also can sell by independent member, is used for the improvement of installing additional of existing above-mentioned setting.
