Abstract[English]
The present application relates to the technical field of fans, in particular to a portable fan. The portable fan provided by the present application comprises a fan assembly, the fan assembly axially supplying air from back to front. The fan assembly comprises: a rotary base, which is provided with radially enlarged parts from back to front; and a plurality of fan blades, which are distributed at intervals on a surface of the rotary base and spirally extend from back to front, wherein the surface of the rotary base protrudes in a radial direction, and is a cambered surface from back to front. An airflow is more effectively guided by means of a relatively smooth arc shape, thereby reducing the loss of the airflow during transfer, and increasing the amount of transferred air.[French]
La présente demande se rapporte au domaine technique des ventilateurs, en particulier à un ventilateur portatif. Le ventilateur portatif selon la présente demande comprend un ensemble ventilateur, l'ensemble ventilateur fournissant axialement de l'air de l'arrière vers l'avant. L'ensemble ventilateur comprend : une base rotative qui est dotée de parties radialement élargies de l'arrière vers l'avant ; et une pluralité de pales de ventilateur qui sont réparties à intervalles sur une surface de la base rotative et s'étendent en spirale de l'arrière vers l'avant, la surface de la base rotative faisant saillie dans une direction radiale et étant une surface bombée de l'arrière vers l'avant. Un flux d'air est guidé plus efficacement au moyen d'une forme d'arc relativement lisse, ce qui permet de réduire la perte du flux d'air pendant le transfert et d'augmenter la quantité d'air transférée.[Chinese]
本申请涉及风扇技术领域，特别涉及一种便携式风扇，本申请提供的便携式风扇包括风扇组件，风扇组件自后向前轴向送风，风扇组件包括：旋转座，自后向前具有径向增大的部分；多片扇叶，间隔分布在旋转座的表面，自后向前螺旋延伸；其中，旋转座的表面径向凸出，自后向前呈弧面。实现了通过较光滑的弧线形状更有效地引导风流，降低风流在传送时损失，提高送出的风量。
