Up and down retractable window screen device for windows and its operating method

Abstract

The invention discloses an up-down-retractable gauze window device for a window and an operation method thereof. The up-down-retractable gauze window device comprises a gauze window body (8) mounted in a window top wall (22) and can extend and retract in the window top wall (22). Thus, when the gauze window body (8) extends down to a window bottom wall (21), the window can be shielded, and when the gauze window body (8) retracts up into the window top wall (22), the window can be opened. By using the up-down-retractable gauze window device, the state of the gauze window body can be adjusted according to the requirements of a user; when the gauze window body needs to be used for shielding the window, the gauze window body can extend out so that mosquitoes can be prevented from flying into the window; and when the gauze window body does not need to be used for shielding the window, the gauze window body can retract up into the window top wall (22), so that the gauze window body can be concealed and avoid being insolated by sunlight for a long time, and the service life of the gauze window body can be prolonged.
