Abstract

The utility model discloses a bladeless fan air inducing assembly which comprises a rotary shaft, a motor with the rotation speed of 500-4000 turns per second and an impeller assembly. The impeller assembly comprises at least two impellers which are fixed to the rotary shaft at intervals, and the rotary shaft and the motor are fixed together. The bladeless fan air inducing assembly can solve the problem about how to obtain enough air volume at a small rotation speed.

Description

Without blade fan air inducing assembly

Technical field

The utility model relates to a kind of constituent elements without blade fan, a kind of without blade fan air inducing assembly specifically.

Background technique

Be used at present life and the fan that uses of office space mainly contains two kinds, a kind of is traditional blade fan that has, and another kind is comparatively popular in blade fan recently.The current motor that is only provided with a drives impeller without blade fan, the boost capability of its air-flow is low, motor and impeller need high speed operation could obtain enough air outputs, generally with at least speed rotation of 5000rpm, what have even can reach 8000rpm or 9000rpm, so high rotational speed, can make without blade fan, in the process of work, to produce very large noise, has affected user's normal use.

Model utility content

The purpose of this utility model is to provide a kind of without blade fan air inducing assembly, and solution as how less passing on can obtain enough air outputs equally.

Without blade fan air inducing assembly, comprise that rotatingshaft, a rotating speed are motor, the impeller sets that 500-4000 per second turns; Impeller sets comprises at least two impellers, being fixed on above-mentioned rotatingshaft of above-mentioned impeller each interval, and this rotatingshaft and motor are fixed together.

Impeller in described impeller sets is all fixed on the same side of motor.

Described impeller sets has two impellers.

Impeller in described impeller sets is fixed on the both sides of motor.

Described impeller sets has two impellers.

Without blade fan air inducing assembly, comprise the rotatingshaft of at least two each intervals, the motor identical with rotatingshaft quantity, above-mentioned motor speed is that 500-4000 per second turns, impeller sets; What each rotatingshaft was corresponding is fixed together with each motor, is fixed with at least one impeller sets on this rotatingshaft, and impeller sets comprises at least one impeller.

On described rotatingshaft, be fixed with two impellers, these two impellers are distributed in the same side of rotatingshaft.

On described rotatingshaft, be fixed with two impellers, these two impellers are distributed in the both sides of rotatingshaft.

The beneficial effects of the utility model are:

1, when adopting a rotatingshaft and motor, in order to meet enough air outputs, the special impeller that two or more is installed on rotatingshaft, these impellers have formed the structure of series boosting, even if motor turns under the following slow-speed of revolution and also can meet enough air outputs 4,000 like this, guarantee that noise is also very little simultaneously.

2, when adopting a plurality of rotatingshafts, motor, impeller, utilize quantitative advantage, these impellers have formed the structure of series boosting, even if motor turns under the following slow-speed of revolution and can meet enough air outputs too 4,000, guarantee that noise is also very little simultaneously, and rotatingshaft also can only an impeller need to be installed just passable, must use two above impellers when adopting a rotatingshaft and motor, thereby reduce installation difficulty.

Embodiment

Please refer to Fig. 1, in this embodiment without blade fan air inducing assembly, comprise that a longer rotatingshaft 1, rotating speed are 4,000 motors that turn 2, an impeller sets; Impeller sets comprises two impellers 3, being fixed on above-mentioned rotatingshaft 1 of this two impeller 3 each intervals, and this rotatingshaft 1 is fixed together with motor 2, and the impeller 3 in figure is i.e. belows, the same side in motor 2.Under the drive of motor 2, rotatingshaft 1 drives 3 runnings of two impellers simultaneously, even if the rotating speed of motor 2 only has 4,000 to turn like this, but the air quantity of deriving is that the air quantity that 8,000 thousand motors that turn 2 are derived is consistent with rotating speed, has also reduced noise simultaneously.In actual use, the rotating speed of motor 2 can select rotating speed lower, as long as the quantity of impeller 3 can increase just passable accordingly.

Please refer to Fig. 2, the place without blade fan air inducing assembly and embodiment 1 difference is in this embodiment that the position of blower fan 2 is not identical, blower fan 2 is mounted between two impellers 3 i.e. head and the tail two ends in this embodiment, and this installation belongs to prior art, therefore no longer too much describe.

Please refer to Fig. 3, in this embodiment without blade fan air inducing assembly, comprise two shorter transmission shafts 1, two motors 2, two impellers 3; Thereby parts of a parts and other are corresponding in these parts, form one group, i.e. transmission 1, motor 2, an impeller 3 are in conjunction with forming one group, even if use so more slow-revving motor 2, as long as quantity has got on, air output can reach the air output of the motor that rotating speed is high equally, and noise reduces by 30% left and right through test.In actual applications, can on each motor 2, increase as required one or more impeller 3, as described in

embodiment

1 and 2, thereby can better reduce noise, and two motors 2 in Fig. 3 are upper-lower position relations, also can make as required the position relationship of as parallel to each other in two motors 2 and dislocation of parallel position relationship etc., certainly, this just need to increase some horizontal areas accordingly by the former blower-casting that holds motor 2.

What above-mentioned three embodiments described is all the air inducing assembly without blade fan, without other parts of blade fan and the position of air inducing assembly and these parts and annexation, all can, with reference to prior art, at this, no longer too much describe.

Finally it should be noted that and it should be understood that the only unrestricted the technical solution of the utility model in order to explanation of above embodiment.Although the utility model is had been described in detail with reference to above-described embodiment, but those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, and do not depart from spirit and scope of the present utility model, and claims are intended to contain and fall into these modifications of the utility model spirit and scope and be equal to replacement.
