Detailed description of the invention
Being preferred embodiment described in detail to blower of the present invention below in conjunction with the accompanying drawings.
The overall structure of blower of the present invention described in accompanying drawing 1,3,5, it mainly includes body 1 and outer tube 2, the device that motor and fan etc. are implemented to blow, air suction function is necessary it is provided with in body 1, outer tube 2 is hollow pipe, 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 regulation wind speed of blower of the present invention is to change to amass size by the air output of air outlet 3 and flow cross-sectional, and the most all of regulation is both for what the structure of outer tube 2 was carried out.First in the circumferential side wall of outer tube 2, offer multiple exhaust vent 21, circumferential side wall along outer tube 2 is distributed the most side by side, but only distribution one section, these exhaust vents 21 are opened by it and are closed, and adjust the air output in air port 3 to realize the first order speed governing of blower of the present invention；Secondly the shape of air outlet 3 is designed to the special graph being made up of multistage camber line shown in the drawings, the path being easy to flow through air-flow switches over, 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 simultaneously pass through these three air outlet, if needing to improve wind speed, then these three air outlet is isolated, air-flow is only flowed out from middle main air outlet 31, thus realizes the second level speed governing of blower of the present invention.
As the presently preferred embodiments, the two-stage speed governing of blower of the present invention is realized by regulating element.Owing to 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 isolates, exhaust vent 21 closes-and air outlet 3 do not isolates, 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 " is due to close with the air-out effect that " exhaust vent 21 close-air outlet 3 do not isolate " realizes, the most preferred scheme of blower the most of the present invention is third gear speed governing, i.e. first gear low or first gear (exhaust vent 21 open-air outlet 3 do not isolate), the second gear middling 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 the most corresponding these three gear.
As further preferred version, third gear speed governing is only realized by a regulating element, i.e. regulation ring 4.Regulation ring 4 is set on outer tube 2, and can rotate around outer tube 2；Multiple adjustment hole 41 corresponding with exhaust vent 21 is offered on it, when regulating ring 4 and rotating, will necessarily be connected with exhaust vent 21 in certain position adjustments hole 41, now exhaust vent 21 is in an open position, the wind of body 1 blowout is understood some and is spilt at exhaust vent 21, thus reduces the speed of the air-flow from air outlet 3 blowout；When adjustment hole 41 staggers with exhaust vent 21 or is turned directly to the region not having exhaust vent 21, exhaust vent 21 is blocked, and the most no longer leaks out, and the air velocity of air outlet 3 blowout can improve.It addition, in this preferred version, regulation ring 4 is combined by the first semi-ring and the second semi-ring, such as it is connected by screw, advantage of this is that and be conducive to depanning when manufacturing regulation ring 4, be simultaneously also beneficial to dismantle regulation ring 4, each parts keeped in repair and cleans.
Being provided with rotating inner tube 5 in outer tube 2, the effect of rotating inner tube 5 is to realize the change to long-pending through air outlet 3 flow cross-sectional, namely to left air outlet 32, right air outlet 33 and the isolation of main air outlet 31.The preferred structure of rotating inner tube 5 sees accompanying drawing 7, its main body is hollow pipe, 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 connect 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 be completely by completely isolated for above three air outlet, this position is referred to as 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, fix with regulation ring 4 and be connected, and can be along with regulation ring 4 synchronous axial system, the connectivity slot angle position in circumference is determined by calculating, so can allow user only when rotating regulation ring 4 in the same direction, it is achieved the change successively of above three gear.
As shown in accompanying drawing 1-2, blower now is in low or first gear, adjustment hole 41 connects with exhaust vent 21, exhaust vent 21 fully opens, connectivity slot 51 connects whole air outlet 3, stop part 52 is also not located in isolated location, and the air-flow therefore being had by air outlet 3 has the cross-sectional area of maximum, and such wind speed is minimum；As shown in Figure 3-4, blower now is in middle speed gear, and adjustment hole 41 no longer connects with exhaust vent 21, exhaust vent 21 is closed, connectivity slot 51 connects whole air outlet 3, and stop part 52 is again without being in isolated location, and wind speed now improves than low or first gear；As seen in figs. 5-6, blower now is in top gear, exhaust vent 21 is still closed, but stop part 52 is through rotating already at isolated location, air outlet 3 is isolated into main air outlet 31, left air outlet 32 and right air outlet 33, air-flow is only by middle main air outlet, 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, it is possible to realize the airflow effects reached needed for humidity, small space.
As another embodiment, it is also possible to by two-stage speed governing separately, i.e. arranging two non-interference regulation rings, two regulation rings are sheathed on outer tube 2 the most rotationally；Wherein offer adjustment hole above the first regulation ring, for controlling opening and closing of exhaust vent 21, second regulation ring is fixing with rotating inner tube to be connected, for adjusting the state in air port 3, remaining structure is identical with aforementioned preferred embodiments, advantage of this is that and be not limited to three speed stages, at user option leeway is bigger.
Compared to prior art, blower of the present invention realizes changing the effect of cold air blast velocity by changing the cross-sectional area of air outlet, it is to avoid increase multiple motor speed regulation stall or multiple standby outer tube, simple in construction simultaneously, reduce manufacturing cost, offer convenience to user.
Above-described embodiment is only for technology design and the feature of the explanation present invention; its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this; can not limit the scope of the invention with this; all equivalence changes made according to spirit of the invention or modification, all should contain within protection scope of the present invention.
