Abstract
The utility model discloses a fan which comprises a support and a motor. The motor is of the structure that a rotor is arranged outside and a stator is arranged inside, the stator is fixedly installed on the support, the rotor is connected to the stator in a rotary and sleeved mode, the stator is hollow, the two ends of the stator are opened so that an inner ventilating duct continuously communicated with the external air can be formed, an inner blade is contained in the fan, one end of the inner blade is fixedly connected with the rotor, and the other end of the inner blade extends to the opened position of one end of the stator. According to the fan, the stator of the motor of the fan is hollow, the inner blade is arranged, one end of the inner blade is fixedly connected with the rotor, and the other end of the inner blade extends to the opened portion of one end of the stator. The rotor is operated and drives the inner blade to rotate along with the rotor so that air can be driven by the inner blade to flow, air flow flows from a ventilating opening, and therefore the work efficiency of the axial flow fan is improved, heat generated by operation of the axial flow fan is taken away by air, the phenomenon that due to overheating of the fan, the service life of the fan is shortened is avoided, and the service life of the fan is prolonged.
Description
Technical field
The utility model relates to a kind of blower fan.
Background technique
Blower fan is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure.The mechanical energy of rotating by handle is converted to gas pressure energy and kinetic energy, and a kind of machinery that gas is transferred out.And the height of the size of the power consumption of blower fan, efficiency is the focus that the user pays close attention to always.Traditional blower fan generally has that power consumption is high, efficiency is low, the easy overheated short shortcoming of service life of fan that causes of motor.
The model utility content
The utility model has overcome above-mentioned the deficiencies in the prior art, provides a kind of efficiency high, can avoid the blower fan of motor overheating.
The technical solution of the utility model is achieved in that
A kind of blower fan, comprise bearing, motor, described motor is external rotor inner stator structure, stator is fixedly mounted on bearing, the rotor rotating sleeve is connected on stator, and stator hollow and both ends open form with ambient air and keep the interior ventilation flue connected, and described blower fan includes interior fan blade, one end and the rotor of interior fan blade are fixedly linked, and the other end of interior fan blade extends to the aperture position place of stator one end.
Adopted working principle of the present utility model and the beneficial effect of technique scheme to be:
The stator of the utility model fan motor is set to hollow shape, and is provided with interior fan blade, and an end and the rotor of interior fan blade are fixedly linked, and the other end of interior fan blade extends to the aperture position place of stator one end.The rotor running can drive interior fan blade and turn round together, interior fan blade drives air draught and flows, allow air draught flow from ventilated port, improved the working efficiency of axial-flow blower, and air draught is taken away the heat that the axial-flow blower running produces, prevent blower fan because overheated causing minimizing in working life, the working life of having improved blower fan.
The accompanying drawing explanation
The cross sectional representation that Fig. 1 is blower fan in embodiment.
Embodiment
Embodiment of the present utility model is as follows:
Embodiment: a kind of blower fan, as shown in Figure 1, comprise bearing 4, motor, described motor is external rotor inner stator structure, and stator 2 is fixedly mounted on bearing 4, and rotor 1 rotating sleeve is connected on stator 2, stator 2 hollows and both ends open form with ambient air and keep the interior ventilation flue 3 connected, described blower fan includes interior fan blade 5, and an end and the rotor 1 of interior fan blade 5 are fixedly linked, and the other end of interior fan blade 5 extends to the aperture position place of stator 2 one ends.
Claims (1)
