Abstract
The utility model relates to a blower, comprising a blower volute, a wind wheel arranged in the blower volute, a motor driving the wind wheel to rotate and a protective cover arranged outside the motor. The blower is characterized in that a wind inlet is arranged on the blower volute, the front end of the motor extends into the blower volute from the wind inlet, the diameter of the wind inlet is larger than the diameter of the motor, thereby forming a wind inlet gap, a fixing device for fixing the blower is arranged between the motor and the blower volute, and a wind inlet grid is arranged onthe protective cover fixed on the blower volute. The blower has the advantages of small size, more beautiful shape, nice heat radiation of the motor, saving materials and the like.
Description
Technical field
The utility model relates to a kind of blower fan.
Background technique
Existing blower fan comprises volute of blower, is located at the wind wheel in the volute of blower and drives the motor that wind wheel rotates; Motor is mounted in the outside of volute of blower, and protective net is installed on volute of blower.Its volume is big, and the heat radiation of motor is not fine, also compares waste material.
The model utility content
The utility model is to overcome the deficiencies in the prior art and provide a kind of volume little, and the good heat dissipation of motor is saved a kind of blower fan of material.
In order to achieve the above object, the utility model is achieved in that it is a kind of blower fan, comprises volute of blower, is located at the wind wheel in the volute of blower and drives the motor that wind wheel rotates; It is characterized in that: have a wind inlet on volute of blower, the front end of motor stretches in the volute of blower from wind inlet, thereby the bore of wind inlet is provided with between motor and volute of blower and makes its fixing fixing device greater than the diameter formation air intake gap of motor; Comprise also being located at the outer protective housing of motor that be provided with air-inlet grille on protective housing, this protective housing is fixed on the volute of blower.
Described fixing device comprises and is fixed on the support bracket more than three on the volute of blower inwall and is fixed on the supporting frame more than three on the electric machine casing, and the supporting frame support is on support bracket and fixing.
Being provided with the assembly wall support bracket at described volute of blower wind inlet is fixed on the assembly wall.
The support block that also comprises the support assembly wall that is fixed on the volute of blower.
The utility model advantage compared with prior art is, volume is little, and profile is more attractive in appearance, and the good heat dissipation of motor is saved material.
Description of drawings
Fig. 1 is an explosive view of the present utility model;
Fig. 2 is the assembling stereogram of Fig. 1;
Fig. 3 is the structural representation after the assembling of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the utility model is done further detailed description:
As shown in Figures 1 to 3, a kind of blower fan comprises volute of blower 6, is located at the wind wheel 2 in the volute of blower and drives the motor 3 that wind wheel rotates; Characteristics of the present utility model are: have a wind inlet 62 on volute of blower 6, the front end of motor 3 stretches in the volute of blower from wind inlet, thereby the bore of wind inlet also helps the heat radiation of motor greater than the diameter formation air intake gap of motor; Between motor and volute of blower, be provided with and make its fixing fixing device; Comprise also being located at the outer protective housing 1 of motor that be provided with air-inlet grille 11 on protective housing, this protective housing is fixed on the volute of blower, the protective net before this protective housing has replaced.
In the present embodiment, fixing device comprises three support brackets 5 that are fixed on volute of blower 6 inwalls and is fixed on three supporting frames 4 on motor 3 housings, also can establish four support brackets and four supporting frames, the supporting frame support is also fixing on support bracket, thereby motor and volute of blower are fixed.Be provided with assembly wall 63 at volute of blower wind inlet 62, support bracket 5 is fixed on the assembly wall.In order to make firm being fixed on the volute of blower 6 of assembly wall, on volute of blower, be provided with the support block 64 that supports assembly wall 63.
During work, wind wheel 2 rotates under the drive of motor 3, and the air in the external world in air-inlet grille 11 suction protective housings 1, is entered from the gap between motor and the assembly wall 63 in the volute of blower 6 again and then blown out by exhaust outlet 61.Because wind helps the heat radiation of motor from the outer process of motor.
