Detailed description of the invention
Below in conjunction with accompanying drawing being preferred embodiment described in detail to blower of the present invention.
The overall structure of notebook invention blower in accompanying drawing 1,3,5, it mainly comprises body 1 and outer tube 2, be provided with in body 1 that motor and fan etc. are implemented to blow, the device of air suction function necessity, outer tube 2 is hollow tube, its one end is connected with described body wind outlet, its other end is provided with air outlet 3, is in communication with the outside.
The principle of the adjustment wind speed of blower of the present invention changes to amass size by the air output of air outlet 3 and flow cross-sectional, and therefore all adjustments are all carry out for the structure of outer tube 2.First in the circumferential side wall of outer tube 2, multiple exhaust vent 21 is offered, be generally and distribute along the circumferential side wall of outer tube 2 side by side, but only distribute one section, these exhaust vents 21 are opened and closedown by it, adjust the air output in air port 3 to realize the first order speed governing of blower of the present invention; Secondly the profile design of air outlet 3 is become the special graph be made up of multistage camber line shown in the drawings, the path be convenient to air-flow flows through switches, specifically, air outlet 3 can be divided into main air outlet 31, left air outlet 32 and right air outlet 33, under normal conditions, the air-flow blown out by body 1 can side by side by these three air outlets, if need to improve wind speed, then by these three air outlet isolation, air-flow is only flowed out from the main air outlet 31 of centre, thus realizes the second level speed governing of blower of the present invention.
As preferred embodiment, the two-stage speed governing of blower of the present invention is realized by regulating element.Because every one-level speed governing all has two different conditions, therefore after permutation and combination, have altogether 4 end-state, that is: exhaust vent 21 open-air outlet 3 do not isolate, exhaust vent 21 closes-and air outlet 3 do not isolate, and exhaust vent 21 closes-air outlet 3 isolates, and exhaust vent 21 opens-and air outlet 3 isolates.Wherein last " exhaust vent 21 open-air outlet 3 isolate " due to the air-out effect realized with " exhaust vent 21 close-air outlet 3 do not isolate " close, therefore the most preferred scheme of blower of the present invention is third gear speed governing, i.e. the first gear---low or first gear (exhaust vent 21 open-air outlet 3 do not isolate), the second gear---middle speed gear (exhaust vent 21 close-air outlet 3 do not isolate) and third gear---top gear (exhaust vent 21 close-air outlet 3 isolate), accompanying drawing 1-2, accompanying drawing 3-4, accompanying drawing 5-6 are corresponding respectively these three gears.
As further preferred version, third gear speed governing is only realized by a regulating element, i.e. adjustable ring 4.Adjustable ring 4 is set on outer tube 2, and can rotate around outer tube 2; It offers multiple adjustment hole 41 corresponding with exhaust vent 21, when adjustable ring 4 rotates, will inevitably be connected with exhaust vent 21 in certain position adjustments hole 41, now exhaust vent 21 is in an open position, the wind that body 1 blows out is understood some and is spilt from exhaust vent 21, thus reduces the speed of the air-flow blown out from air outlet 3; When adjustment hole 41 staggers with exhaust vent 21 or directly turns to the region not having exhaust vent 21, exhaust vent 21 is blocked, and no longer leaks out herein, and the air velocity that air outlet 3 blows out can improve.In addition, in this preferred version, adjustable ring 4 is combined by the first semi-ring and the second semi-ring, such as be connected by screw, the advantage done like this is conducive to depanning when manufacturing adjustable ring 4, is also conducive to adjustable ring 4 to be dismantled simultaneously, carries out keeping in repair and clean each parts.
In outer tube 2, be provided with rotating inner tube 5, the effect of rotating inner tube 5 realizes the change to amassing through air outlet 3 flow cross-sectional, also namely to the isolation of left air outlet 32, right air outlet 33 and main air outlet 31.The preferred structure of rotating inner tube 5 is see accompanying drawing 7, its main body is hollow tube, direction of axis line is identical with the axial line of outer tube 2, rotating inner tube 5 offers multiple connectivity slot 51, stop part 52 is naturally form between adjacent connectivity slot 51, under normal circumstances, connectivity slot 51 can be communicated with left air outlet 32, right air outlet 33 and main air outlet 31, and when needs reduction flow cross-sectional amasss, stop part 52 can be blocked between left air outlet 32 and main air outlet 31, and between right air outlet and main air outlet 31, but only when specific turned position, could completely by completely isolated for above-mentioned three air outlets, this position is called isolated location, in accompanying drawing 6 in F-F sectional view, what stop part 52 was in is exactly an isolated location, preferably, rotating inner tube 5 offers 2 connectivity slots 51, be fixedly connected with adjustable ring 4, and can along with adjustable ring 4 synchronous axial system, the angle position of connectivity slot in circumference is determined by calculating, can allowing user so only when rotating adjustable ring 4 in the same direction, realizing the change successively of above-mentioned three gears.
As shown in accompanying drawing 1-2, blower is now in low or first gear, adjustment hole 41 is communicated with exhaust vent 21, exhaust vent 21 is opened completely, connectivity slot 51 is communicated with whole air outlet 3, stop part 52 is not also in isolated location, and therefore have maximum cross-sectional area by the air-flow of air outlet 3 tool, such wind speed is minimum; As shown in Figure 3-4, blower is now in middle speed gear, and adjustment hole 41 is no longer communicated with exhaust vent 21, exhaust vent 21 is closed, connectivity slot 51 is communicated with whole air outlet 3, and stop part 52 is not still in isolated location, and wind speed now improves than low or first gear; As seen in figs. 5-6, blower is now in top gear, exhaust vent 21 is still closed, but stop part 52 is in isolated location through rotating, air outlet 3 is isolated into main air outlet 31, left air outlet 32 and right air outlet 33, air-flow is only by the main air outlet of centre, and therefore the cross-sectional area of air-flow reduces, and wind speed reaches the highest.Through test, the gap between top gear and low speed, middle speed gear is obvious, can realize the airflow effects reached needed for moist, small space.
As another embodiment, also can by two-stage speed governing separately, namely arrange two non-interference adjustable rings, two adjustable rings are sheathed on outer tube 2 all rotationally; Wherein offer adjustment hole above the first adjustable ring, for controlling opening and closedown of exhaust vent 21, second adjustable ring is fixedly connected with rotating inner tube, for adjusting the state in air port 3, all the other structures are identical with aforementioned preferred embodiments, the advantage done like this is not limited to three speed stages, and at user option leeway is larger.
Compared to prior art, blower of the present invention realizes by the cross-sectional area changing air outlet the effect changing cold air blast velocity, avoids and increases multiple motor speed regulation stall or multiple outer tube for subsequent use, and structure is simple simultaneously, reduce manufacturing cost, offer convenience to user.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and implement according to this; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
