Abstract
Provided is a minitype direct current vortex draught fan. Outside air is sucked into a draught fan cooling chamber (11) to cool a direct current motor (9), and then the outside air is pressurized to be pumped out by fan blades. Only an air sucking opening (1) and an air outlet (6) of the entire draught fan are open, and the other parts of the draught fan are all closed. The inside space of the draught fan is effectively utilized, the distance between an air blocking pressurizing base (4) and the fan blades (3) is only a fraction of millimeter, and sufficient wind power can be effectively provided for air pressure. The sucked air cools the vortex draught fan (9) in working first through the draught fan cooling chamber (11), and the entire draught fan can be more durable.
Description
Technical field
The design relates to a kind of miniature direct current whirlpool blower fan, and it is one unexistent efficient mini blower fan on the market, provides enough suction wind-force can to a lot of light portable type equipment.
Background technique
Whirlpool blower fan is on the market the model of high-power more than 100W mostly now, and small-sized DC fan 6V, 12V and so on face again wind-force deficiency, inefficient problem.Be difficult to find one both small and exquisite portable, have again the blower fan model of enough wind-force.
Summary of the invention
It is both small and exquisite portable that the design achieves one, and have again the direct current whirlpool blower fan structure of enough wind-force, it farthest can utilize the kinetic energy of DC micro-motor, produces enough wind-force, carries with type respiratory machine, the demand of the equipment such as aerator to be supplied to.
The design is applicable to the air supplying of small-sized respiratory machine, can effectively utilize effective size, provide lasting wind-force work, and sound is little, lightweight.
In order to solve the problems of the technologies described above, the present invention adopts following technological scheme: minisize dc whirlpool blower fan, is characterized in that: it comprises the steps:
Direct current generator (9) power supply drives fan blade (3) rotary work to produce blast and sucks outside air from intakeport (1), outside air enters blower fan cooling chamber (11) cooling direct current generator (9) and sends into air inlet (12) afterwards, and air is driven by fan blade (3) and discharges from exhaust outlet (6).
The micro-machine that described direct current generator (10) is generally 12V is even less, but it can provide the wind-force of corresponding abundance according to the design.
Described fan blade (3) is the same with blower fan skeleton (2), can by resistance to deformation, the materials such as the plastic aluminum alloy that serviceability is high are made, the supercharging base (4) that keeps out the wind of fan blade (3) one end effectively can strengthen blast, is supplied to pumping chamber (5) and sucks with enough pressure or pump out air.
Described fan blade (3) drives work by motor shaft (8) after being powered by direct current generator (9).
There are front shroud (7) and back shroud (10) sealing and reinforcing before and after described blower fan skeleton (2), prevent air leakage, also effectively can strengthen blast.
Beneficial effect of the present invention is: adopt the design of sealed mode, effectively make use of inner fan space, keep out the wind and only have the distance of a few tenths of a mm between supercharging base (4) and fan blade (3), can effectively supercharging; And first the air of inspiration cools whirlpool blower fan (9) in work by blower fan cooling chamber (11), enable whole blower fan more durable.

Embodiment
In order to make those of ordinary skill in the art's clearly object of the present invention, technological scheme and advantage, arranging below in conjunction with accompanying drawing and enforcement case and the present invention is further elaborated.
As shown in the figure, outside air sucks blower fan cooling chamber (11) to after direct current generator (9) cooling, then is extracted out by fan blade supercharging.Whole blower fan only has intakeport (1) and exhaust outlet (6) other positions to be all sealings, and it can effectively provide blast to have sufficient wind-force, and small volume and less weight, durable highly efficient.
