Abstract

The utility model belongs to an air pump device, comprising a thin-wall sleeve shell which is big in middle and small at both ends. A bracket with an electric motor stable in the middle and ring stands around is fixed in the middle big section of the sleeve. The ring stands are connected with the electric motor stable by at least three connecting rods. The electronic motor stable which is used as a fixed electronic motor support of an electronic motor of the fan blades is fixed on a shaft, with the outside diameter small and almost the same as the diameter of the pipeline. The utility model is particularly applied to a narrow occasion of air pump.

Description

Air pump

The utility model relates to a kind of device of pumped air.

Up to the present, people generally come pumped air with fan or blower, and this fan or blower all have a housing, a motor and a flabellum that is fixed on the motor reel.The external diameter of their flabellum is all many greatly than the external diameter of motor, thereby the diameter of device is more many greatly than the diameter of pumping pipe, can't be applied in the narrower occasion in space.

Task of the present utility model is exactly the shortcoming that will overcome said apparatus, the air pump that provide a kind of external diameter of device less, the diameter of the diameter of pump and pipeline is more or less the same.

Task of the present utility model is finished like this: it also has a housing, a motor and a flabellum that is fixed on the motor reel, but housing is a thin walled cylinder body that two broad in the middle is little that is combined by two one a big little ladder barrel, and the motor that is fixed with flabellum on the axle is fixed on the motor frame in sleeve stage casing.The motor frame is a support, and its center has motor nest, periphery that motor is installed that the ring stand that contact with sleeve is arranged, and guide vane is arranged on the ring stand, has at least three connecting rods to be connected between the annular port of formation between ring stand and the motor nest, ring stand and motor nest.The vanes fixed of flabellum is having on the flabellum dish of convex globoidal.The guide vane on the ring stand and the blade of flabellum are all along the same circumferencial direction embowment of sleeve.

Because housing of the present utility model is a thin walled cylinder body that two broad in the middle is little, two sections the diameter on its stage casing and both sides is more or less the same, motor is fixed on the motor frame in sleeve stage casing, and motor adopts miniature cocurrent electromotor, thereby its external diameter is less, the diameter of pump and the diameter of pipeline are more or less the same, be suitable for use in the narrower occasion in space, be particularly suitable in the air-conditioned room of winding gate that closes the room of door and window or less gap arranged from outdoor to indoor pumped air.

Be elaborated with drawings and Examples below.

Fig. 1 is a structural representation of the present utility model.Fig. 2 is the sectional view along A-A line among Fig. 1.

With reference to accompanying drawing 1, one one a big little ladder barrel 1 and another a big little ladder barrel 2 reverse sockets, cylinder 2 is enclosed within the outside of cylinder 1, be combined into a thin walled cylinder body 3 that two broad in the middle is little, a motor frame 5 is housed in broad in the middle section 4 of sleeve 3, the center of this motor frame has motor nest 6, periphery that ring stand 7 is arranged, and ring stand 7 is positioned at the inner edge of cylinder 1 and contacts with cylinder 1, with at least two screws 8 ladder barrel 1, ladder barrel 2 and motor frame 5 is tightened together.As seen from Figure 2, a plurality of guide vanes 9 that are uniformly distributed along the circumference are arranged on the ring stand 7, form annular port 10 between ring stand 7 and the motor nest 6, have three connecting rods 11 to be connected between ring stand 7 and the motor nest 6, make ring stand and motor nest be linked to be a motor frame.Be fixed with on the axle in the motor nest 6 of motor 13 fixed electrical machinery framves 5 of flabellum 12.The flabellum dish 14 of flabellum 12 is convex globoidal disks, and the arc shaped blade 15 that is uniformly distributed along the circumference is fixed on the convex globoidal of flabellum dish 14.Guide vane 9 on the ring stand 7 is also curved, and identical with the bending direction of flabellum blade 15, promptly all along the same circumferencial direction bending of sleeve.

Behind motor connecting power, motor just drives the flabellum rotation, and air promptly enters from the left end of sleeve 3, exports from right-hand member.

Claims

1, a kind of air pump, it has a housing, a motor and a flabellum that is fixed on the motor reel, it is characterized in that: housing is by two one a big little ladder barrel (1,2) thin walled cylinder body (3) that two broad in the middle that combines is little, the motor (13) that is fixed with flabellum (12) on the axle is fixed on the motor frame (5) of sleeve broad in the middle section (4), there is motor nest (6) at the center of motor frame (5), periphery has the ring stand (7) that contacts with sleeve (3), guide vane (9) is arranged on the ring stand, form annular port (10) between ring stand (7) and the motor nest (6), there are at least three connecting rods (11) to be connected between ring stand and the motor nest, the blade of flabellum (15) is fixed on the flabellum dish (14) of convex globoidal, and the guide vane (9) on the ring stand (7) and the blade (15) of flabellum are all along the same circumferencial direction embowment of sleeve (3).
