Abstract
The utility model provides a novel fan which comprises an impeller with blades, an impeller shaft and a motor, wherein one end of the impeller shaft is fixed, the other end is sheathed with the impeller which is hung in the air and the impeller is driven to rotate by the motor. The utility model is characterized in that the fan is additionally provided with a fixing piece, one end of the fixing piece is fixedly connected with the hanging end of the impeller shaft and the other end of the fixing piece is fixedly connected with other fixing objects. On the basis of not changing the original fan or the fan structure, the utility model avoids the defect that the non-uniform stress of the impeller shaft results in the eccentric friction of a motor stator and a motor rotor to generate heat to burn out the motor through adding a fixing piece to fix the hanging end of the impeller shaft, and has the advantages of work performance enhancement and service life extension.
Description
The utility model provides a kind of novel fan, belongs to the field of accessories of Fan Equipment.
At present, the blower fan that is used for family or produces, its technological scheme impeller, impeller shaft and motors that have flabellum that adopt more, wherein an end of impeller shaft is fixed, and it is unsettled that the other end is set with impeller.When impeller rotates under the drive of motor, because of the imbalance of flabellum and the centrifugal force that runs up bigger, the two ends discontinuity equalization of impeller shaft, between the about 3～5mm of the stator of motor and gap between rotor, impeller shaft rocks the off-centre friction that causes motor stator and rotor and produces heat, and then cause the motor short circuit to burn out, influence life of product.
The utility model provides the two ends stress equalization that provides a kind of impeller shaft, the novel fan that life of product is long.
The utility model provides and is achieved in that
Comprise the impeller, impeller shaft and the motor that have flabellum, wherein an end of impeller shaft is fixed, and it is unsettled that the other end is set with impeller, impeller is by its rotation of driven by motor, set up a fixed block, the free end of one end and impeller shaft is fixedly connected, and its other end and other fixture are fixedly connected.
Described novel fan, fixture are the protective housing of fan, also can be the adjunct beyond the fan.
The utility model compared with prior art, on the basis that does not change original fan or blower fan structure, fix by adding the fixed block end that impeller shaft is unsettled, avoided producing defective hot and then that burn motor because of unbalance stress causes the off-centre friction of motor stator and rotor because of impeller shaft, improve service behaviour, prolonged working life.
Fig. 1 is the utility model one embodiment's a structural representation;
The utility model is described in further detail below in conjunction with accompanying drawing:
Among the figure, one end of impeller shaft 2 is fixed on the motor 1, the other end suit has the impeller 3 of flabellum, impeller 3 rotates under the drive of motor 1, protective housing 4 is fixed on the motor 1 and is covering whole flabellum, a fixed block 5 is established in spoke 6 jointing places at protective housing 4, and fixed block 5 is fixedly connected with the free end of impeller shaft 2, thereby realizes the purpose of stabilization vane wheel shaft 2.
One end of fixed block and the free end of impeller shaft are fixedly connected, and the other end can be fixedly connected on the protective housing of flabellum, also can be fixedly connected on other adjunct beyond the fan, as long as play the purpose of stabilization vane wheel shaft free end.
Claims (3)
1, a kind of novel fan comprises the impeller, impeller shaft and the motor that have flabellum, and wherein an end of impeller shaft is fixed.It is unsettled that the other end is set with impeller, and impeller be is characterized in that by its rotation of driven by motor: set up a fixed block, the free end of one end and impeller shaft is fixedly connected, and its other end and other fixture are fixedly connected.
2, novel fan as claimed in claim 1 is characterized in that: fixture is the protective housing of fan.
3, novel fan as claimed in claim 1 is characterized in that: fixture is the adjunct beyond the fan.
