Title
(EN) FAN
(FR) VENTILATEUR
(ZH) 风扇
Abstract
(EN)
A fan, comprising: a support (10); a head assembly (20) povitably disposed on the support (10); and an air supply assembly (30) povitably disposed on the head assembly (20). During pitch adjustment of the fan, the head assembly (20) remains still, so as to reduce the weight of the part of the fan involved in pitch adjustment, thereby effectively avoiding the problem that the fan falls over. Furthermore, the head assembly (20) that controls the fan to shake the head left and right does not involve in pitch adjustment as the air supply assembly (30), so that problems such as noise, jitter, jamming or stuck failure of the head assembly (20) can be avoided, and the practicability of the fan is improved.
(FR)
L'invention concerne un ventilateur, comprenant : un support (10); un ensemble de tête (20) disposé en pivotement sur le support (10); et un ensemble d'alimentation en air (30) disposé en pivotement sur l'ensemble de tête (20). Pendant le réglage du pas du ventilateur, l'ensemble de tête (20) reste immobile, de façon à réduire le poids de la partie du ventilateur intervenant dans le réglage du pas, ce qui permet d'éviter efficacement le problème de basculement du ventilateur. De plus, l'ensemble de tête (20) qui commande le ventilateur pour faire vaciller la tête vers la gauche et la droite n'intervient pas dans le réglage du pas en tant qu'ensemble d'alimentation en air (30), ce qui permet d'éviter des problèmes tels que le bruit, la gigue, l'enrayage ou une défaillance par blocage de l'ensemble de tête (20), et d'améliorer l'aptitude à la mise en œuvre du ventilateur.
(ZH)
一种风扇,包括:支架(10);机头组件(20),机头组件(20)可枢转地设置在支架(10)上;供风组件(30),供风组件(30)可枢转地设置在机头组件(30)上。风扇在进行俯仰调节时,机头组件(20)保持不动,减轻了风扇俯仰调节的部分的重量,从而有效地避免了风扇出现倾倒的问题,同时,控制风扇进行左右摇头的机头组件(20)不随供风组件(30)俯仰调节,能够避免机头组件(20)出现噪音、抖动、卡顿或卡死失效等问题,提升了风扇的实用性。
