具体实施方式
下面结合附图对本发明的实施列作进一步详细说明。
见图 1、 图 8所示， 主壳体 1上有安装风机系统的面板 2， 主壳体 1后壁上 开有安装挂件的两个开口 16、 17, 两个橡胶柱 18、 19安装在主壳体 1后壁的下 端上。伸缩壳体 3套在主壳体 1的外面， 伸缩壳体 3的下部是吸油烟罩 5， 伸缩 壳体 3和吸油烟罩 5是固定一体的。 套筒 4套在主壳体 1的内径中， 套筒 4的 下部是吸油烟罩 5， 套筒 4和下部吸油烟罩 5固定连接。 网盖 6安装固定在吸油 烟罩 5的端口上。 在主壳体 1与伸缩壳体 3之间有电动升降装置， 该电动升降 装置的升降电机 7安装在主壳体 1的面板 2上， 升降电机 7的主动轴上装有缠 线轮 8， 该缠线 8轮有两个凹槽分别装有钢丝绳， 其中， 一条钢丝绳 9顺时针固 定缠绕在凹形槽中， 另一条钢丝绳 10逆时针固定缠绕在第二条凹形槽中， 两条 钢丝绳分别经安装固定在主壳体 1上的导向轮 11、 12与伸缩壳体 3相连接， 两 个升降件 13、 14的一端对称安装固定在主壳体 1的外壁， 另一端对称安装固定 在伸缩壳体 3的内壁上。 装饰外壳 15套在伸缩壳体 3的外面， 装饰外壳 15的 上端安装固定在主壳体 1的外壁上部。 这样， 就组成电动升降式吸油烟机外壳。
在把电动升降式吸油烟机安装到橱柜里的时候， 首先， 在橱柜的底板上开 有一个与装饰壳体 15相匹配的孔径， 把组装好的电动升降式吸油烟机外壳从橱 柜的底板开口处向上穿过， 再把主壳体 1 的后壁上的两个开口插在橱柜后背板 上的挂件 31上， 两个橡胶柱 18、 19就顶在后背板上。 这样， 电动升降式吸油 烟机外壳就被稳定的放置在橱柜里。
图 2给出了电动升降式吸油烟机外壳伸出时的结构示意图， 在使用时按下 开关， 安装在主壳体 1的面板上升降电机 7就会转动做放的动作， 该升降电机 7 的主动轴上的缠线轮 8放出钢丝绳 9、 10， 经安装在主壳体的导向轮 11、 12提 拉着伸缩壳体 3向下运行， 在升降件 13、 14的作用下伸缩壳体 3被缓缓的垂直 的从橱柜低板的开口出伸出， 并超出了主壳体 1 的长度， 吸油烟罩 5就抵近了 灶台。 同时， 套筒 4也随着吸油烟罩 5从主壳体 1的内孔向下伸出， 延长了烟 道。
再次按下开关， 升降电机 7就会转动做收的动作， 钢丝绳 9、 10经安装在 主壳体 1上的导向轮 11、 12向上提拉着伸缩壳体 3， 在两个升降件 13、 14的作 用下，伸缩壳体 3、套筒 4及吸油烟罩 5垂直向上缓缓的上升回到原来的位置上。 这样， 吸油烟机的外壳就实现了可以电动升降使用的目的。

图 4给出了另一种电动升降装置的结构示意图， 装有电机的液压泵 24安装 固定在主壳体 1的面板 2上， 两个伸缩臂 25、 26的上端分别对称安装固定在主 壳体 1外壁上， 下端分别对称安装固定在伸缩壳体 3的内壁上， 液压泵 24的两 个油管 27、 28分别与两个伸缩臂 25、 26相连接。 当液压泵 24开动做放的动作 时， 油压就会顺着两条油管 27、 28传向伸缩臂 25、 26， 伸缩臂 25、 26就会提 拉着伸缩壳体 3向下缓缓的垂直伸出。 当液压泵 24开动做收的动作时， 油压就 会顺着两条油管 27、 28收回， 伸缩臂 25、 26就会提拉着伸缩壳体 3向上缓缓 上升回到原来的位置上。 这样， 吸油烟机的外壳就实现了可以电动升降使用的 目的。
图 5给出了另一种电动升降装置的结构示意图， 两个电动推杆 29、 30的上 端对称安装固定在主壳体 1上， 下端分别对称安装固定在伸缩壳体 3上。 当开 动电机， 电动推杆 29、 30做放的动作时， 缩在壳体里的推杆就会向下推出， 电 动推杆 29、 30就会提拉着伸缩壳体 3向下缓缓的垂直伸出。 当开动电机， 电动 推杆 29、 30做收的动作时， 伸出的推杆就会向上收回， 电动推杆 29、 30就会 提拉着伸缩壳 3 向上缓缓上升回到原来的位置上。 这样吸油烟机的外壳就实现 了可以电动升降使用的目的。
图 6给出了另一种电动升降装置的结构示意图， 它的收和放的动作和过程 与图 2给出的实施例是一样的， 所不同的是图 6给出的实施例是采用了两个电 机 7和 7 '， 并且共用一个控制开关， 每一个电机单对一个升降件做功， 同时收 或放。 这样， 吸油烟机的外壳同样实现了可以电动升降使用的目的。
与之相类似的， 图 7给出了另一种电动升降装置的结构示意图， 它的收和 放的动作和过程与图 3给出的实施例是一样的， 所不同的是图 7给出的实施例 是采用了两个电机 7和 7 '， 并且共用一个开关， 每一个电机单对一个升降件做 功， 同时收或放。 这样， 吸油烟机的外壳同样实现了可以电动升降使用的目的。
图 8为电动升降式吸油烟机外壳的俯视图， 给出了主壳体 1、 伸缩壳体 3、 装饰壳体 15、 吸油烟罩 5是长方形的电动升降式吸油烟机外壳。
本发明如果安装上风机系统就是一个完整吸油烟机。 本发明做为吸油烟机 安装风机系统的一个平台， 可以满足风机系统在以后的改进和变化。 当然， 本 发明所指主壳体、 伸缩壳体、 装饰外壳、 吸油烟罩也可以为圆形、 正方形、 长 方形或其它适用形状以及它们相互间的各种组合， 升降件也可以是市场上常见 的直线轴承、 抽屉滑道、 齿条、 丝杠等各式各样的升降件。 这样的变换均落在 本发明的保护范围之内。
