Specifically, technical problem to be solved in the utility model is: provide a kind of novel fan, extends the working life of bearing, improves the usability of blower fan.
For solving the problems of the technologies described above, the technical solution of the utility model is, a kind of novel fan is provided, described novel fan comprises housing, described housing is rotatablely equipped with transmission shaft by bearing, the described transmission shaft being positioned at described housing is provided with impeller, described housing is provided with suction port and air outlet, described suction port is relative with described impeller, described transmission shaft connecting power device, described housing is provided with air-flow path, described housing is positioned at described bearing both sides and is equipped with a circular groove, circular groove described in two is all communicated with described air-flow path, the outside of described housing is provided with the pipeline being communicated with described air outlet and air-flow path.
In novel fan described in the utility model, as a kind of optimal technical scheme, described housing is provided with end cap, and described end cap has a flange, and the end face of described flange and described bearing leans.
In novel fan described in the utility model, as a kind of optimal technical scheme, described flange is provided with some breach, and described gap position is corresponding with described circular groove position.
In novel fan described in the utility model, as a kind of optimal technical scheme, described housing and drive axle support are provided with the first felt, at the described circular groove of described case inside between described first felt and described bearing.
In novel fan described in the utility model, as a kind of optimal technical scheme, be provided with the second felt between described end cap and transmission shaft, described breach is between described second felt and described bearing.
Have employed technique scheme, the beneficial effects of the utility model are:
(1) be equipped with owing to housing being positioned at bearing both sides the circular groove being communicated with air outlet by air-flow path, the high pressure draught of air outlet can be utilized to purge circular groove, to change the pressure condition of bearing both sides, form partial high pressure, avoid dust to enter the roller of bearing to damage bearing, thus extend the working life of bearing.
(2) because housing and drive axle support are provided with the first felt, when the high pressure draught of air outlet is introduced into, just form a zone of high pressure between first felt and bearing, dust just can not enter this zone of high pressure by the first felt, thus improves the working life of bearing.
(3) owing to being provided with the second felt between end cap and transmission shaft, when the high pressure draught of air outlet is introduced into, also form a zone of high pressure between second felt and bearing, dust just can not enter this zone of high pressure by the second felt, thus further increases the working life of bearing.
