Abstract
The utility model relates to an air intake device, which is formed by an upper cover (11) and a base (12) fastened with the upper cover (11). The upper cover is provided with a reticular vent (111) and is fastened in the base. The opening of the vent is smaller than the opening of the vent of an air intake structure in the prior art. The base is cup-shaped, one end of the base is fastened with the upper cover and the other end of the base is connected with a ventilation pipe. Since the air inlet of the air intake device provided by the technical scheme of the utility model is small, impurities are not apt to be sucked in; and since the upper cover is fastened with the base, the air intake device can be installed from inside to outside and from outside to inside, and the disassembling is very convenient.
Description
Technical field
The utility model relates to the air filtration technology, relates in particular to the air-intake device that products such as a kind of automobile, engineering truck, air-conditioning use.
Background technology
All need to use a kind of air-intake device in the application of products such as automobile, engineering truck and air-conditioning.Air-intake device of the prior art adopts bigger air inlet mostly, and majority shows as the flaabellum shape structure.The air intake effect of this structure is better, but sucks some impurity easily.If be impurity such as dust, then be typically provided with screen pack, so generally not severe owing in the connected ventilation shaft; If but sucked solid refuses such as some leaves, polybag from air inlet, would then stop up ventilation shaft and screen pack easily, thereby can influence the air intake effect, and be difficult to cleaning.
The utility model content
The purpose of this utility model provides a kind of air-intake device, solves the above-mentioned defective that air inlet structure exists in the prior art.
In order to achieve the above object, the technical solution of the utility model proposes a kind of air-intake device, and this device is made up of the loam cake (11) and the base (12) of mutual snapping; Described loam cake has cancellated air vent (111), and buckles in the described base, and air vent aperture efficiency air inlet structure opening of the prior art is little; Described base is cup-shaped, and an end and described loam cake interlock, and the other end is connected with ventilation shaft.
In the above-mentioned air-intake device, described loam cake also comprises the thin cylinder (112) that is positioned at described air vent below, and described loam cake promptly utilizes this cylinder to buckle in the described base.
In the above-mentioned air-intake device, described base comprises have tapering transition thick, thin two cylindrical portions may of (123), and described loam cake promptly buckles into described thick cylindrical portions may (121), and described thin cylindrical portions may (122) then is connected with ventilation shaft.
In the above-mentioned air-intake device, be evenly distributed with four openings (113) around the thin cylinder of described loam cake, described opening is provided with outstanding horizontal stripe (114); The thick cylindrical portions may inwall of described base then has a circle groove (124), match with horizontal stripe on the described thin cylinder opening snapping of described loam cake of realization and base of this groove.
In the above-mentioned air-intake device, described air vent is made up of the some vertical bar intersections of facing horizontal stripe and band inclined-plane directly.
The air-intake device air inlet that technical solutions of the utility model provide is less, is difficult for sucking foreign material; And loam cake and base are mutual snappings, can outwards install from the lining, also can outside in install, and dismantle also very convenient.
Description of drawings
Fig. 1 is the loam cake two sides view of the utility model air-intake device;
Fig. 2 is the base two sides view and the cutaway view of the utility model air-intake device;
Fig. 3 is the assembling three-dimensional view of the utility model air-intake device.
The specific embodiment
Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
Fig. 1～3 are respectively loam cake two sides view, base two sides view and the assembling three-dimensional view of the utility model air-intake device, and shown in Fig. 1～3, air-intake device of the present utility model is made up of the loam cake 11 and the base 12 of mutual snapping.Wherein, loam cake 11 has cancellated air vent 111, and buckles in the base 12, and air vent 111 aperture efficiencies air inlet structure opening of the prior art is little; 12 of bases are cup-shaped, and one end and loam cake 11 interlock, and the other end is connected with ventilation shaft.
Furthermore, in the air-intake device of the present utility model, loam cake 11 also comprises the thin cylinder 112 that is positioned at air vent 111 belows, and loam cake 11 promptly utilizes this cylinder 112 to buckle among the base 12.12 of bases comprise thick, thin two cylindrical portions may with tapering transition 123, and the cylinder 112 of loam cake 11 promptly is to buckle into thick cylindrical portions may 121, and 122 of thin cylindrical portions may are connected with ventilation shaft.In addition, be evenly distributed with four openings 113 around the thin cylinder 112 of loam cake 11, be equipped with two outstanding horizontal stripes 114,115 on the opening 113; Thick cylindrical portions may 121 inwalls of base 12 then have a circle groove 124 (shown in cutaway view among Fig. 2), and this groove 124 matches with above-mentioned one of them horizontal stripe 114 and promptly realizes the snapping of loam cake 11 and base 12.
In addition, as shown in Figure 1, above-mentioned netted air vent 111 is intersected by some horizontal stripe 111a and vertical bar 111b to be formed, and wherein horizontal stripe 111a faces directly, and vertical bar 111b then can be with certain inclined-plane, thereby can avoid sucking foreign material in the realization air intake.
In sum, the air-intake device air inlet that technical solutions of the utility model provide is less, is difficult for sucking foreign material; And loam cake and base are mutual snappings, can outwards install from the lining, also can outside in install, and dismantle also very convenient.
More than be preferred forms of the present utility model, according to the disclosed content of the utility model, those of ordinary skill in the art can expect some identical, replacement schemes apparently, all should fall into the scope of the utility model protection.
