Abstract

【物品用途】;　　本創作為用於鼓風機之扇輪。;【創作特點】;　　如各圖所示，本創作為一圓盤狀扇輪，其由中心朝外徑向延伸一軸面，並於軸面之頂面外周緣沿軸向朝下彎曲，且軸面之底面朝上內凹而形成一碟狀本體，該碟狀本體環周具有多數呈軸向且等間隔設置之葉片，其中於碟狀本體頂面之葉片軸向長度較長，而於碟狀本體底面之葉片軸向長度較短，且各葉片寬度係朝徑向延伸並形成一弧形段，以使各葉片之徑向外側末端朝同側偏擺。此外，各葉片於軸向之兩末端於相對朝內之一側係形成一相向之圓滑缺角。;　　整體觀之，本創作藉由其整齊、對稱之獨特造型設計，而可予人一種樣式新穎之獨特視覺感受，且本創作於申請前未見於刊物或被公開使用，因而符合新式樣專利申請要件，故申請人爰依法提出申請。[Use of the article]; This invention is a fan wheel for a blower.; [Features of the invention]; As shown in the figures, this invention is a disc-shaped fan wheel, which has an axial surface extending radially from the center, and is axially bent downward at the outer periphery of the top surface of the axial surface, and the bottom surface of the axial surface is upwardly concave to form a disc-shaped body, and the disc-shaped body has a plurality of blades arranged axially and at equal intervals around the circumference, wherein the axial length of the blades on the top surface of the disc-shaped body is longer, and the axial length of the blades on the bottom surface of the disc-shaped body is shorter, and the width of each blade is extended radially and forms an arc segment, so that the radial outer end of each blade is deflected toward the same side. In addition, each blade forms a smooth notch facing each other at the two ends of the axial direction on the opposite inner side. ; Overall, this creation can give people a unique visual experience of novel style through its neat and symmetrical unique design. Moreover, this creation has not been seen in publications or used publicly before the application, so it meets the requirements for new design patent application, so the applicant filed an application in accordance with the law.
