Automatic air door

自动电风门

Abstract

The utility model relates to an automatic air door, comprising a driving motor, a control circuit, a block board. The driving motor drives the driving worm to rotate, the worm drives the turbine to rotate, and the rotation of the turbine drives a baffle to shield over or depart from the wind port. The turbine shaft, in fixed or moving mode, drives the baffle to rotate or move by the rotation of the turbine shaft or itself, so that the effect of wind port shielding by the baffle or deviation therefrom is achieved. Beneficial effect of the utility model is that the automatic air door can flexibly open or close the wind duct baffle in order to effectively preventing air ventilation between inside and outside, and solve the problem of absolute isolation between inside and outside of the duct.Therefore, wind and other objects are prevented from entering the wind duct from the wind port, and the air door is simple in construction, convenient for installation. Smoke discharging efficient canbe enhanced by over 20% by adopting the air door, and effect is more favorable by adopting a pull type electric air door, wherein no resistance exists on the wind duct block board. A turn-over type electric air door can solve the problem of incapability of using the pull type electric air door due to inadequate horizontal position thereof.
一种自动电风门,包括驱动电机、控制电路、挡板,所述驱动电机驱动蜗杆转动,蜗杆带动涡轮传动,涡轮的转动带动挡板遮挡或偏离风口。涡轮轴采用固定或者活动的方式,通过涡轮轴转动或者自身移动带动挡板转动或者移动,从而实现挡板遮挡或者偏离风口的效果。本实用新型的有益效果是,自动电风门可灵活开启或关闭风道挡板,有效防止内外的空气流通,解决通道内外严密隔离的问题,有效地防止风气及其他物体通过风道进入风道内,同时结构简单,安装方便。可提高20%以上的排烟效率,特别是抽拉式电动风门,风道挡板无阻力,效果更佳。翻转式电动风门可解决因横向位置不够,不能使用抽拉式电动风门的效果。
