Description

The clamshell of air bells exhauster

Technical field

The utility model relates to a kind of air cushion that improves structure.

Background technique

The structure of general scroll-type air bells exhauster, basically be that clamshell by a scroll casing shape is a main body, and establish a rotary blade with curve of the blade in the inside of clamshell, wherein rotary blade and clamshell are eccentric state configuration, and make the periphery of rotary blade and the inner edge of clamshell form not isometric big, little air chamber, and its clamshell is provided with a wind inlet at the axial position that corresponds to rotary blade, and be provided with an exhaust outlet in the radial position that corresponds to rotary blade of atmospheric air chamber, when rotary blade rotates, air can be drawn in the clamshell through rotary blade central authorities by wind inlet, its air promptly extrudes to the rotary blade periphery with high flow rate, turns to the exhaust outlet of atmospheric air chamber to discharge then.

Because the principle of air compression, the air port of its scroll-type air bells exhauster must be with the bigger atmospheric air chamber position of periphery and clamshell space that radially is arranged at rotary blade; Again, the rounded scroll casing shape of its clamshell so general air bells exhauster commonly used mostly is the solid bolster of other face down bonding of exhaust outlet that is engaged in clamshell, is firmly bridged in use for whole air bells exhauster, and is formed one for the bonded structure between air bells exhauster and assembly.Yet, so will limit the exhaust outlet direction of air bells exhauster and significantly reduce the applicability of whole air bells exhauster.

Summary of the invention

At the shortcoming that above-mentioned prior art exists, the utility model provides a kind of clamshell of air bells exhauster.

The technical solution adopted in the utility model is: a kind of clamshell of air bells exhauster, the clamshell of its air bells exhauster is provided with a wind inlet at the axial position that corresponds to rotary blade, and is provided with an open exhaust outlet section in the radial position that periphery corresponds to rotary blade; It is characterized in that: the outer rim of this clamshell is contacted with assembly as continuing surface by clamshell one side wherein when using for being polygonal body, and air bells exhauster is firmly put.

The inside of this clamshell is provided with the rotary blade that is eccentric state configuration with clamshell.

This clamshell is to be main body by two symmetrical polygonal side plates, between biside plate and by a connecting piece, connected, this connecting sheet is to surround into a scroll casing shape with exhaust outlet section in the mode with the side plate inscribe, and this rotary blade promptly is located on the inboard plate body of side plate wherein, the plate body that this wind inlet promptly is molded over another side plate corresponds to the center of rotary blade, and constitute complete air bells exhauster structure, and this side plate is formed with the continuing surface of kink shape in its each edge.

This side plate is provided with on the continuing surface at each edge and makes things convenient for the screw perforation that air bells exhauster combines with the locking of assembly, and the appropriate position of the continuing surface breach that has the motor power line of being convenient to rotary blade to wear again.

The periphery cloth of connecting sheet is shown the lug of bent fastening, the then corresponding inserting hole that can supply lug to wear that is provided with on the plate body of its side plate.

The wind inlet place of this clamshell is provided with a guard.

The utility model is a main body by two symmetrical polygonal side plates, between biside plate and by a connecting piece, connected, its connecting sheet be with the mode of side plate inscribe around becoming a scroll casing shape with exhaust outlet section, and the inboard plate body of side plate is provided with a rotary blade therein, and be formed with wind inlet, and constitute complete air bells exhauster structure in the center that the plate body of another side plate corresponds to rotary blade.

The rotatable air bells exhauster of the utility model uses to select different continuing surfaces, to change the air-out direction of air bells exhauster.

The motor power line that the utility model is convenient to rotary blade wears.

The utility model saves the space of rotary blade and motor drive shaft distance, and effectively reduces rocking of rotary blade.

Embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

The structure of the whole air bells exhauster of the clamshell of the utility model air bells exhauster as shown in Figure 1, be that clamshell 1 by a scroll casing shape is main body, and be provided with a rotary blade 2 in the inside of clamshell 1, wherein rotary blade 2 is eccentric state configuration with clamshell 1, and make the periphery of rotary blade 2 and the inner edge of clamshell 1 form not isometric big, little air chamber, and its clamshell 1 is provided with a wind inlet 115 at the axial position that corresponds to rotary blade 2, and be provided with an open exhaust outlet section 121 in the radial position that clamshell 1 periphery corresponds to rotary blade 2, when rotary blade 2 rotates, can be with air by wind inlet 115, be drawn in the clamshell 1 through rotary blade 2 central authorities, its air promptly extrudes to rotary blade 2 peripheries with high flow rate, turns to then by exhaust outlet section 121 to discharge.

Please cooperate simultaneously and consult Fig. 2 and shown in Figure 3, emphasis of the present utility model is to be the main body of whole clamshell 1 by two symmetrical polygonal side plates 11, and connected by a connecting piece 12 11 of biside plates, the periphery cloth of its connecting sheet 12 is shown the lug 122 of bent fastening, the then corresponding inserting hole 114 that can supply lug 122 to wear that is provided with on the plate body of its side plate 11, bend again after its connecting sheet 12 promptly utilizes lug 122 and the inserting hole 114 of side plate 11 places mutually and fasten with the effects that reach and side plate 11 mutual assemblings are connected, and with the mode of side plate 11 inscribes around becoming a scroll casing shape with exhaust outlet section 121, and its rotary blade 2 promptly is installed on the inboard plate body of side plate 11 wherein, and set into air port 115, and constitute complete air bells exhauster structure in the center that the plate body of another side plate 11 corresponds to rotary blade 2.
