Description

M252813 V. 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 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.

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

M252813 V. 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. Please refer to the drawings below for a detailed description of this creation in the following preferred embodiment: First, 'please read the first, second, and third illustrations' This creation is mainly provided with a rotor (1), the rotor (1) Positions on both sides of the body near the periphery

A gift-shaped structure base for the disc (2) ^ This creation is based on the independent rotor formed from the integral plate of the ring plate (3 1), the leaf and the disc (2), and 3) the structure. Such an operation = (32)-the impeller composed of body molding (welded or riveted to the rotor, which can save the customary structure, the metal disc must be a piece of blade, and the operation process can also be omitted. The rotor (f welded to the impeller operation method created by Imotomoto. The way is set up the disc (^). The peripheral system is made of plastic injection. The specific gravity is relative to the conventional structure. ^ Ji f & therefore the disc (2) structure The counterbore (1 1) φ of 1) is much lighter, so when the rotor (take the rotating flat of the rotor (1) = weights (1 2) such as a block to obtain a lighter weight (amaranth) At the same time, it can be carried out by using one of the mass (1) and the disc (2). Using the rotor 1 of this creation to adjust the rotation balance, the implementation mode = the rotor (and fast. Operation ' It does look relatively simple and the conventional structure is relatively made of a heavy disk because the specific gravity of the Celsius disk is relatively heavy. When the metal circle takes the balance of the rotor, this 詷 $ Feng Nuo is therefore applying a weight body to Demand and difficult to operate. It seems relatively bulky and slow when the peripheral position of the rotor (1) is equipped with one), and the ring plate (31) and Yeyue /, the formed disc (2, the impeller (3), and other two independent ^ ^ Composed of one-piece, after 70 kings of mouth; then impeller

Creation instructions (6) (3) The convex posts (321) on the blades (32) fit into the through holes (21) of the disc (2) of the rotor (1), correspondingly, at the same time, The hot-melt technology is used to fuse the convex post (3 2 1) and fix it. In this way, the two independent impeller (3) structures and the rotor (结构) structure are welded to each other into a connected state, and A combined structure of a rotor (1) and an impeller (3) is formed. This structural combination form of this creation can not only effectively and effectively streamline the manufacturing process of the product, and thereby relatively improve the work efficiency of the industrial product; at the same time, it can also have a relatively large proportion of the quality of the toilet due to the structure of the disc (2) around the rotor (1) It is much lighter, so that the rotor (1) is relatively simple and fast when adjusting the rotation balance. In summary, this creation uses the technology of plastic injection molding to first produce the rotor (1) and the disk (2) as a whole, and the ring plate " and the blade (32) are integrated into one. Impeller (3) and other two independent structures, and then the two independent impeller (3) structure and rotor (1) structure are welded by heat fusion technology into a combined structure.
