Creation Instructions (1) [Technical Field of the New Type] This creation is about the rotation of a centrifugal fan, especially the rotor and impeller of a cooling fan. It is a technology that uses plastic injection to form a single body. The one-piece structure, the ring plate and the blade, and then the impeller and the rotor are fused into a combined structure of the rotor and the impeller by thermal fusion technology. This structure simplifies the manufacturing process of the product and enhances the industry's composition. For the centrifugal fan structure composition technology, its main composition technology is a profitable way. A structure is integrally formed around the rotor, and the disc is directly formed to tightly combine with the formation of the rotor. Through holes listed on the panel. At the same time, a plastic impeller is formed by using plastic injection. The structure of the impeller is composed of regularly arranged blades, and the ring plate is made of blades. The cross section of the ring plate is slightly curved, which is slightly W shape; and the blades are directly formed on the convex surface, and each blade is a straight blade with a plurality of convex posts on the other end. The convex posts can be inserted into the rotor discs in a corresponding manner to fuse the convex posts of the blades so that the rotor is closed. [Prior art] The structure of the rotor and the connection between the singularity and the singularity are effective. The rotor uses a plastic impeller with a square impeller set on the periphery. The combined structure forms the structure of the rotor and the impeller, and the ring plate is effectively connected to form an upright shape. The hole and the leaf are integrated with the oblique connection, the same blade, and then the shape of the wheel is qualitative and present. The disk rotors that are manufactured in an out-of-the-box manner are connected in a continuous pattern on the end face when the ring plate is formed.
H01P0302.ptd 第5頁 M252813 五、創作說明(2) 按,先前技術,例如_華民國專利公報公告編號第5 0 8056號「鼓風式風扇之扇輪構造」專利案,其係由一環牆 中心設中心軸,該環牆底邊向外延伸有底板,底板上設複 數之葉片,其特徵在於:該底板與環牆之接合位置環繞設 有圓弧璧面。 惟查,上述專利前案之葉輪構造係由轉子的底板上直 接生成若干直立狀的葉片,這種形態的葉輪構造只適合應 用於小風量的小型風扇來使用之;因為該葉輪的每一片葉 片都是呈獨立的狀態,該葉片只有在底部的位置與轉子的 底板形成連結狀態,而葉片的頂部則是形成獨立的懸空狀 態;因此這種葉輪的葉片必須製造得短小一些,才不會在 葉輪旋轉的時候因為風力的衝擊作用而造成葉片的震動現 象,也就是說這種短小型的葉片構造只適合使用於小型的 風扇;反之對於大型的風扇而言,這種獨立而懸空狀態的 葉片結構是不適宜使用於大型的風扇。H01P0302.ptd Page 5 M252813 V. Creation instructions (2) Press, the prior art, for example, the patent case of “Hua Ming Patent Gazette Bulletin No. 5 08056“ Structural Structure of Fan-type Fans ”, which consists of a ring wall A central axis is provided at the center, a bottom plate extends outward from the bottom edge of the ring wall, and a plurality of blades are arranged on the bottom plate, which is characterized in that a circular arc surface is arranged around the joint position of the bottom plate and the ring wall. However, the impeller structure of the aforementioned pre-patent case is directly generated from the rotor's bottom plate by a number of upright blades. This type of impeller structure is only suitable for small fans with small air volume; because each blade of the impeller They are in an independent state, and the blade only forms a connection with the bottom plate of the rotor at the bottom, and the top of the blade forms an independent suspension state; therefore, the blades of this type of impeller must be made shorter to prevent When the impeller rotates, the vibration of the blade is caused by the impact of the wind. That is to say, this short and small blade structure is only suitable for small fans. Conversely, for large fans, such independent and suspended blades The structure is not suitable for large fans.
再者,例如中華民國專利公報公告編號第4 7 9 7 6 0號「 軸流式風扇之扇葉構造」專利案,其係包含有一轉動轴及 其外側圓周上以幅射狀延設出預定數目之扇葉;其主要特 徵在於:各扇葉概呈直立狀,並使各扇葉接近轉動轴外圓 周表面一適當距離之下方皆具有一個缺口,而外侧便形成 一厚韌部,並以一約呈水平狀之環板連接於各扇葉的厚勃 部底侧端面作一銜接使用者。 以及’例如中華民國專利公報公告編號第5 3 〇丨2 7號「 離心型葉輪及空氣清淨裝置」專利案,其之離心型葉輪屬In addition, for example, the patent publication of the Republic of China Patent Gazette No. 4 7 9 7 60 "the blade structure of an axial flow fan" patent, which includes a rotating shaft and a predetermined extension in the form of a radiation on its outer circumference. The number of fan blades is mainly characterized in that each fan blade is almost upright, and each fan blade has a gap below an appropriate distance from the outer circumferential surface of the rotating shaft, and a thick and tough portion is formed on the outer side. An approximately horizontal ring plate is connected to the bottom end surface of the thick part of each fan blade for connecting users. And 'for example, the patent case of the Republic of China Patent Gazette No. 5 3〇 丨 2 7 "centrifugal impeller and air purification device" patent case, the centrifugal impeller belongs to

Creation instructions (3) With a core plate connected to the motor shaft and a side plate corresponding to the core plate; between the above core plate and the above side plate, the direction of circumference = $ is set to tilt in the opposite direction of rotation The centrifugal type of the backward vane = two, which is characterized in that: from the outer periphery of the side plate, the vane length is about i leaf 'i / 3 · 5), and the backward vane is bent and rotated toward the vane ^ 2) The exit portion is inclined, and the exit angle of the exit portion of the side plate in the tangential direction is about 40 degrees to about 60 degrees. " However, it is found that although the impeller structure of the two patent cases mentioned above can be a large fan, the blade structure of this kind of impeller must be connected to the impeller structure one by one; The one-piece connection and the operation mode combined with the impeller are indeed multi-worked and time-consuming, not to mention the main goal of economic benefits. [New content] This creation is aimed at the centrifugal fan structure, creating a combined structure of the rotor and the impeller of the centrifugal fan. Its main purpose is to make the rotor and the impeller by plastic injection technology. A separate structure of the element structure, and then the rotor and the impeller are fused to form a combined state by means of hot-melt technology, thereby forming a combined structure of the rotor and the impeller; this structure can effectively simplify the operation process of the product, and then relatively To improve the work efficiency of products.
