The wind guide is configured to have a spiral shape and is asymmetric; the wind guide "around" is used to introduce the airflow into the air inlet in a progressive manner, and the other two winds can be Wei Wei Vertically perpendicular to the upper surface of the upper casing, the shape is further reduced to reduce the airflow of the airflow, thereby reducing the noise during the air supply, and the other 4 M407300 is fitted with the wind guiding structure. The setting of the airflow can be adjusted firstly before entering, which will be more conducive to reducing the air movement, improving the stability, and reducing the chewing sound, and also allowing the kinetic energy of the power mechanism to maximize the benefits. The present invention will be fully understood by the following examples, so that those skilled in the art can make it according to the following examples. However, the present application may not be restricted by the following embodiments. Referring to Figure 1, there is shown a schematic diagram of a blower motor structure according to a preferred embodiment of the present invention. Place The air supply motor structure includes an upper casing 1 一下, a lower body 2 〇, a power mechanism 3 〇, and a fan, wherein the upper casing H) includes an upper plate; 2 and ^ from the upper __ The lower extension _ 14 ' and the upper (four) towel recording is provided with an inlet wind 94 and then the lower housing 2 includes a lower plate 22 and an upward extending from the lower plate at the center of the lower plate - a % of protrusions to form a space for accommodating the movable raft 7 below the casing and a central portion of the bulge % is provided with a through hole 28, which can be used to "" The extension shaft 32' thus allows the fan 4G to be driven over the extension shaft 32 via the lower housing 20 and is driven by the power mechanism 3〇, so that when the second casing is combined, 'only The fan 4〇 is wrapped between the upper and lower casings, and the power is further formed and the lower casing 2 is formed to form an air outlet/the fourth (four) port structure Na to combine the produced air supply motor knots. The rotation of the shot '10' is directed to the direction in which the airflow passes through the tuyere/claw. Therefore, in the case of the face of the 1_2 Me*, based on the air outlet The fan's turning direction will be in the counterclockwise direction (looking down from the top of the fan), and (4) the upper bunk and the chamber enclosed by the bamboo body will form a ring air duct that directs the airflow to the air outlet. 5〇 / 5 M407300 After the airflow enters the casing, the fan 4〇 driven by the power mechanism 30 will drive the airflow, and different wind pressures will be generated by the difference in the rotational speed. Therefore, in addition to the power mechanism 3 itself In addition to stability, the structure of the fan 40 and the design of the air duct also have a decisive influence on the stability of the pressure.

百无’將射以垂直於底板的方式設置是為了提供最大的推動面積， 以將動力機構3〇所提供的能量轉換為最大的推動力，再者，由於風扇為圓 形設計’且進風σ 16位於風扇40的正中央上方，因此，若扇葉尺寸皆相 同的話’會造細心部分的扇葉密度最高，而越往賴的密度越低，如此 來第-’當相對而s較不穩定的新進氣流剛進入時，所遭遇的會是密 f最高的騎配置’在此情形下，職生_動、風切、噪音等也相對而 D會較大，n氣流往外嶋散進人風道時，雖細周外圍的切速度 較高，但扇葉密度的不斷降低，卻會造成加速氣流所需的推動力不增反減， 因而使得動力機構30必須提供更大的動力來達到目標流速，但這樣的加速 部也同時讓上述因新進氣流所產生的擾動、噪音更為加劇；第三，密度不 平均的扇f設計也料讓縣在旋射因不平衡而產生噪音。 ^監於上述的理由’本創作採用了至少二種尺寸的扇葉，利用較小尺 2一扇#46提_義物度，如㈣，她糊同一尺 :^的ifI在職哺速下’根縣創作所設計的風扇㈣減少新進 ==_，也輯_於外__力，相當有助於供麵 m如峨計也在力學平衡上提供了綱配置方式， 6 :==不具彎曲度的扇葉，這樣的設計可以在帶動氣流旋轉時 :持;::：·，減少動力機構的負擔， 作的絲藝吉」 再者’由第3B圖可以看出，根據本創 則是可以讓氣、4禮設計為自^雄二邊不睛低的枝，趙的設計 定==___^同樣_噪音以及提升穩 在此’ _意岐，軸在第3A騎齡 受限:而且，也一扇葉之間皆夹設二個第二扇葉等，並不 際需求而進行娜…、種的扇葉’此外’扇葉的彎曲度也可視實 降至最低m，①全沒有聞。此外，為了將氣體流動路徑上的阻力 也是，上下殻體與側壁之間的接合處皆採用圓弧設計。 示了上述有關扇葉結構的改進之外，更進一步地，在該上板上方還可 另e曼環繞在該進風口周圍的一 士 ^ 整流，進而提高氣流的穩定性。π M U進人前’絲氣流進行 板平由中央的進風口 16進入，且進風角度涵蓋了整個上 ㈣了 ’職人殼咖氣流相歸 作所提出的導風結構18 _ 例，4圖以及第5圖’其分別顯示了根據本創作—另—較佳實施 例中%I風結構的送風馬達結構的-示意^以及—上觸。在此實施 形狀^ Γ構Μ是被垂直設置於殼體上’且具有一類似蜗牛殼的螺旋 ==生^其除了《直_具有匯集氣流的作用外，更可因螺旋 沿猶物行__，糾，她是，由於該 ==8並非對稱齡佈於進風口 16的周圍，如第5圖所示，而是偏 此，其在引魏體流向_時，亦會迫飢流越來越接近進風 M407300 16，也就是’驗會由左上方距離峡吨遠處進入導風結構I 導風結構18而沿著逆時鐘方向前進，並因此而距離進風口 16越來越 _，導風結構18幾乎切齊進風口 16，也讓氣流順利進入進風口 Μ，如 此一來’氣流除了會受到垂直構造的限制而減少絲外 =絲越^賴口 16職計而麵績叙神具_顧動導; =了此實施例的導風結構設計還能減少新進_ 、度洛差，降低風扇帶動新進氣流所需的動力，減少動力 而增進供氣的穩定性。 J㈣進 當然，第4圖所示僅為導風結構的其中一種可能，並非作為 導風結構也可以形成為如漏斗的結構，亦即，不與上板η垂^, t達成集中乳流的效果，或是形成為漏斗加上螺旋的結構等， 流進入前達成整流效果的結構，都屬於本創作的範圍。 、月匕亂 以及卿的送風馬達結構所提供的特殊風_設計， 以及叹置於進風口外_特導風結構，除了可提升氣 少氣流擾動所產蝴音外，也讓動力機構咖_最大的2及減 ❿ 縱2本創作已由上叙實_詳細敘糾可域悉本轉之人士 匠思而為献修飾’然皆不脫如㈣請專利範圍所欲保護者。 【圖式簡單說明】 第1圖：其顯示根據本創作的一送風馬達結構的-分散示意圖； 第2圖：其顯示根據本創作的一送風馬達結構的-結合示意圆. 第跡其顯示根據本創作一較佳實施例的一風扇的一上視圖. ㈣圖縣卿—較佳細的—風制一側視圖； 第=其顯示根據本創作一另—較佳實施例，具 馬達結構的-結合及 構的送風 第5圖：其顯示根據本創作一另—較佳實施例，具有一導風結構的送風 8 M407300 馬達結構的一結合上視圖。 【主要元件符號說明】 10 上殼體 12 上板 14 側壁 16 進風口 18 導風結構 20 下殼體 22 下板 24 側壁 26 凸起 28 通孔 30 動力機構 32 延伸軸 40 風扇 42 底板 44 第一扇葉 46 第二扇葉 50 出風口 50a 第一出風口結構 50b 第二出風口結構The No.'s shot is placed perpendicular to the bottom plate to provide the maximum push area to convert the energy provided by the power mechanism 3〇 into the maximum driving force. Furthermore, since the fan is circular, it enters the wind. σ 16 is located above the center of the fan 40. Therefore, if the fan blades are all the same size, the density of the blade will be the highest, and the density of the blade will be the lower, so that the first is not the opposite. When the stable new intake air flow just enters, it will encounter the highest riding configuration. In this case, the occupational _ movement, wind cut, noise, etc. are also relatively large, and D will be larger. In the air duct, although the cutting speed around the periphery is higher, the density of the blade is continuously reduced, but the driving force required to accelerate the airflow is not increased or decreased, so that the power mechanism 30 must provide more power to reach The target flow rate, but such an acceleration part also makes the above-mentioned disturbances and noises caused by the new intake air flow more intensive; thirdly, the fan-f design with uneven density also causes the county to generate noise due to unbalanced rotation. ^ Supervised for the above reasons 'This creation uses at least two sizes of fan blades, using a smaller ruler 2 a fan #46 _ 义义度, such as (four), she pastes the same rule: ^ ifI in-service speeding' The fan designed by Genxian County (4) reduces the new incoming ==_, also the _ outside __ force, which is quite helpful for the surface m, such as the trick, also provides a configuration mode on the mechanical balance, 6 :== without bending The fan blade, such a design can drive the airflow when rotating:::::·, reduce the burden on the power mechanism, and make the silk art.” Furthermore, as can be seen from Figure 3B, according to this creation, It is possible to let the gas and the 4 rituals be designed as the branches that are not low on the two sides of the masculine. The design of the singer is ==___^ The same _ noise and the steadiness is stable here. _Intention, the axle is limited in the 3rd age: and, Also, there are two second blades, etc., between the leaves, and the Na, the fan blade 'in addition' the curvature of the fan blade can be reduced to a minimum of m. . In addition, in order to make the resistance on the gas flow path, the joint between the upper and lower casings and the side walls is designed in a circular arc. In addition to the above-described improvements in the structure of the blade, further, a single pass around the air inlet can be rectified above the upper plate to improve the stability of the air flow. Before the π MU enters the front, the silk airflow is carried out by the central air inlet 16 and the air inlet angle covers the entire upper (four) air guiding structure proposed by the 'personal shell air flow phase'. 18 _ Example, 4 figure and Figure 5 is a schematic representation of the structure of the air supply motor of the %I wind structure according to the present invention. In this case, the shape is configured to be vertically disposed on the casing and has a spiral similar to the snail shell == raw ^ in addition to the "straight_ has the function of collecting airflow, but also because of the spiral along the yoke _ _, correct, she is, because the ==8 is not symmetric around the air inlet 16, as shown in Figure 5, but this is the case, when it leads to the body flow _, it will also hunger The closer to the intake air M407300 16, that is, the inspection will advance from the upper left side of the gorge to the wind guiding structure I wind guiding structure 18 and proceed in the counterclockwise direction, and thus the air inlet 16 becomes more and more _, The air guiding structure 18 is almost cut into the air inlet 16 and also allows the airflow to smoothly enter the air inlet Μ, so that the airflow is limited by the vertical structure and the wire is reduced, and the wire is more than the wire. The guide structure design of this embodiment can also reduce the new _, the degree of lag, reduce the power required by the fan to drive the new intake air flow, reduce the power and improve the stability of the air supply. J (4) Advance, of course, Figure 4 shows only one of the possibilities of the wind guiding structure, not as a wind guiding structure or a structure such as a funnel, that is, not with the upper plate η, t to achieve concentrated milk flow The effect, or the structure formed into a funnel plus a spiral, etc., the flow into the structure to achieve the rectification effect before, belongs to the scope of this creation.
