Abstract
A window-shades mechanism with an anti-backflow function is applied to a fan device and an electronic apparatus. The window-shades mechanism includes a supporter, a blade, a shaft and a connecting rod. The blade is disposed inside the supporter and includes two sides. Each side includes a first region and a second region. The shaft is connected to the supporter and the blade. The connecting rod is connected to the second region on the side of the blade. The connecting rod has a holding portion. When the connecting rod is moved by the holding portion, the blade is driven to rotate relative to the supporter via the shaft.
Claims20
A window-shades mechanism with an anti-backflow function, comprising:
- a supporter;
- a blade disposed inside the supporter and comprising two sides, each side having a first region and a second region adjacent to each other;
- a shaft connected to the supporter and the first region of the two sides of the blade;
- and
- a connecting rod, two sections of the connecting rod being respectively connected to the second regions of the two sides of the blade, the connecting rod having a holding portion, and the connecting rod rotating the blade relative to the supporter via the shaft when the holding portion is moved by weight of a fan unit.
A fan device with an anti-backflow function, comprising:
- a housing, having a first wall and a second wall opposite to each other, the first wall and the second wall respectively comprising a hole structure;
- at least one window-shades mechanism disposed on one of the first wall and the second wall and corresponding to the hole structures, wherein the window-shades mechanism comprises:
- a supporter connected to the housing;
- a blade disposed inside the supporter and comprising two sides, each side having a first region and a second region adjacent to each other;
- a shaft connected to the supporter and the first region of the two sides of the blade;
- and
- a connecting rod connected to the second region of the two sides of the blade, and the connecting rod having a holding portion;
- and
- a fan unit detachably disposed inside the housing, the connecting rod rotating the blade relative to the supporter via the shaft when the fan unit presses the holding portion to move the connecting rod.
An electronic apparatus with an anti-backflow function, comprising:
- a base, having a first area, a second area and a third area connected to each other;
- and
- a fan device disposed on the second area, wherein the fan device comprises:
- a housing, having a first wall and a second wall opposite to each other, the first wall and the second wall respectively comprising a hole structure;
- at least one window-shades mechanism disposed on one of the first wall and the second wall and corresponding to the hole structures, wherein the window-shades mechanism comprises:
- a supporter connected to the housing;
- a blade disposed inside the supporter and comprising two sides, each side having a first region and a second region adjacent to each other;
- a shaft connected to the supporter and the first region of the two sides of the blade;
- a connecting rod connected to the second region of the two sides of the blade, and the connecting rod having a holding portion;
- and
- a fan unit detachably disposed inside the housing and located between the hole structures of the first wall and the second wall, the connecting rod driving the blade to rotate relative to the supporter via the shaft when the fan unit presses the holding portion and moves the connecting rod, so as to move the blade away from the hold structures and to connect the first area and the third area.
