Embodiment
As shown in Figure 1, for the erection drawing of the dust extraction fan for notebook computer of the present utility model, as shown in Figure 2 and Figure 3, for the structural representation of dust extraction fan removing upper casing 1 of the present utility model, from Fig. 1-Fig. 3, dust extraction fan comprises: upper casing 1, fan guard 2, the motor (not shown) being placed in the rotating part 3 in fan guard 2 and driving rotating part to rotate, in addition, also comprise: be placed in the air channel converter for converting air compressing air channel and the open air channel of air between fan guard and rotating part; The steering control device regulating sense of rotation for controlling motor be electrically connected with motor; The switch gear converting air compressing air channel and the open air channel of air for controlling air channel converter according to the sense of rotation of motor be connected respectively with air channel converter and steering control device.
Dust extraction fan of the present utility model, controls the action of motor, to make rotating part forward or reverse by arranging steering control device; By arranging switch gear and air channel converter, clockwise or when rotating counterclockwise, air compressing air channel and the open air channel of air mutually can be changed at rotating part, thus make air channel can be suitable with the sense of rotation of rotating part.Therefore, be no matter rotating part clockwise or be rotated counterclockwise, the dust removing effects of fan is all the same, and, rotating part can be rotated counterclockwise for a long time, increases the dust removal performance of fan, improves working life and the performance of fan, heat dispersion improves, and reaches the object promoting Consumer's Experience.
Wherein, as shown in Figure 2 and Figure 3, air channel of the present utility model converter comprises: be arranged on rotating part 3 both sides and interconnective a pair dunnage 4,5; Be separately positioned on a pair dunnage top and a pair whirlpool tongue 6,7 given prominence to towards rotating part 3; Wherein, a pair dunnage can be rotated relative to fan guard, so that in two whirlpool tongues one can near rotating part, and another can away from rotating part.Air compressing air channel can be formed at rotating part and between its a whirlpool tongue, the open air channel of air can be formed between rotating part and another whirlpool tongue away from it.
Concrete, a pair dunnage of the present utility model and fan guard can adopt the structure shown in Fig. 4, wherein, a dunnage 5 in a pair dunnage is hinged by link 11 and fan guard 2, and the bottom of a pair dunnage 4,5 also adopts hinged Placement (as shown in Figure 4, Figure 5), so that dunnage 5 can be rotated relative to fan guard 2, and also can relatively rotate between dunnage 4 and dunnage 5.Wherein, link 11 can be bolt, pin etc.
Or, a pair dunnage of the present utility model and fan guard can also adopt the structure shown in Fig. 6, wherein, a fixed plate 12 is settled by mode that is hinged or welding at fan guard inwall, again that the bottom of a pair dunnage 4,5 is hinged with fixed plate respectively, thus make a pair dunnage can distinguish opposing fixed plate rotation.
Further, as shown in Figure 2 and Figure 3, air channel converter also comprises the connecting rod 8 hinged respectively with a pair whirlpool tongue between a pair whirlpool tongue 6,7 of being arranged in a pair dunnage 4,5.A pair whirlpool tongue can be made to realize interlock by connecting rod 8, namely when a whirlpool tongue is near rotating part, another whirlpool tongue away from rotating part, thus will inevitably form an air compressing air channel and an open air channel of air between a pair whirlpool tongue and rotating part.In addition, air channel converter also comprises the elastic component 10 for being connected with fan guard 2 by whirlpool tongue 7, and this elastic component can adopt spring, can be returned to initial position for making connected whirlpool tongue 7 under the effect of its restoring force.
Wherein, dunnage of the present utility model can be formed in one with the whirlpool tongue being arranged on its top, and other Placement also can be adopted to be fixed together.
In order to make a pair whirlpool tongue of air channel converter can relatively rotate part translation with away from or near rotating part, the utility model adopt switch gear to control conversion that air channel converter carries out air compressing air channel and the open air channel of air.
Wherein, switch gear adopts the structure that automatically can control whirlpool tongue motion, and as shown in Figure 1-Figure 3, switch gear comprises: be arranged on fan guard 2 outside and the element 9 for generation of magnetic of an aligning whirlpool tongue 6; Be arranged on the proximity detector (not shown) on notebook computer casing or mainboard; Be arranged on the push-button switch (not shown) be connected on notebook computer casing and with the element for generation of magnetic.Accordingly, the whirlpool tongue that the element 9 for generation of magnetic is aimed at is made up of iron material, and is electromagnet for generation of the element of magnetic.Wherein, switch gear also can adopt the structure of prior art.
Specifically describe the working procedure of the utility model dust extraction fan below.
When motor rotates forward (e.g., making rotating part produce along rotary motion clockwise in Fig. 3), button press switch, makes button come close to or in contact with proximity detector, and proximity detector can produce corresponding signal makes electromagnet be energized, when the solenoid is energized, produce the magnetive attraction attracting its whirlpool tongue 6 aimed at, make whirlpool tongue 6 mobile towards the direction (namely towards the left side of rotating part) away from rotating part 3, when whirlpool tongue 6 moves, drivening rod 8 and whirlpool tongue 7 synchronously move towards left side, now, the spring be connected with whirlpool tongue 7 is in the state of being stretched, therefore an active force towards right side can be produced, whirlpool tongue is hindered to move to the left, finally, the pulling force that electromagnet produces whirlpool, left side tongue 6 and the pulling force of spring to whirlpool, right side tongue 7 reach balance, a pair whirlpool tongue stops mobile, make the inwall of whirlpool tongue 6 near fan guard in left side, the open air channel of air is formed between whirlpool, left side tongue and rotating part, and the whirlpool tongue 7 on right side near rotating part and and rotating part between form air compressing air channel, thus when rotating part is rotated, there is good air channel, good performance can be obtained, system is made to ensure good radiating requirements.
And when motor reversal, rotating part rotates in the counterclockwise direction, makes electromagnet power-off, then electromagnet disappears to the magnetic attraction of whirlpool tongue 6, now, the whirlpool tongue 7 on right side moves to the right under the effect of spring-return power, and the whirlpool tongue in left side also synchronously moves to the right under the drive of connecting rod, finally, the whirlpool tongue on right side is near fan guard, between whirlpool, right side tongue 7 and rotating part, form the open air channel of air, and the whirlpool tongue 6 in left side is near rotating part, and forms air compressing air channel with rotating part.
In sum, the dust extraction fan with a pair whirlpool tongue of the utility model design can regulate a pair whirlpool tongue to relatively rotate distance partly according to the sense of rotation of rotating part automatically, thus make rotating part clockwise or be rotated counterclockwise time can form the open air channel of good air and air compressing air channel, ensure the performance of fan forward or reverse, and reversion is carried out for a long time, improve the dust removing effects of fan, add the working life of fan, improve the Consumer's Experience of system.
Although be explained in detail the utility model above; but the utility model is not limited thereto; those skilled in the art can modify according to principle of the present utility model; therefore, all various amendments carried out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
