实施例3：Example 3:
本实施例的一种带有除尘功能的离心式风机，其工作原理为：电机启动后，带动转动轴转动14，同时设置在转动轴14上的离心叶轮座10与离心叶轮片15同轴转动，形成与外部空气压力差，使空气从第一外壳16的进风口吸入，又在如图5所示的向后式结构的离心叶轮片15的作用下，促使吸入的空气在离心力的作用下把气体引向远离转动轴14的离心方向，从而使空气贴着风机外壳1的内壁流动，并轴向从第二外壳17的出风口流出。因为在靠近的内壁设置有金属吸附环11，导电金属通电使吸附环11具有了对微尘的静电吸附作用，当带着灰尘的空气沿着电机外壳1内壁流动到吸附环11时会被吸附到吸附环11上，再由离心叶轮座10带动转动的除尘铲把吸附环11上堆积的灰尘铲进除尘铲内，特别的，除尘铲中的除尘铲摇臂6以摇臂安装轴8为支点，推力弹簧7在推动摇臂一端时，使另一端固定的铲体5的进尘端在动态过程中始终贴合在吸附环11上，被铲入的铲体5的灰尘受到吸附环11的吸附力堆积在铲体5内底部后端，从而能够及时地清理掉吸附环11上吸附的灰尘，使吸附环11一直保持良好的清洁状态，避免吸附环11的吸附能力下降。在风机停下时可以卸下电机座3和电机座支撑臂2，及时清理堆积的灰尘，从而保证设置在出风口后端的电机3的清洁。A kind of centrifugal fan with dust removal function in this embodiment, its working principle is: after the motor is started, it drives the rotating shaft to rotate 14, and the centrifugal impeller seat 10 and the centrifugal impeller blade 15, which are arranged on the rotating shaft 14, rotate coaxially , to form a pressure difference with the outside air, so that air is sucked from the air inlet of the first housing 16, and under the action of the centrifugal impeller blade 15 of the backward structure as shown in Figure 5, the sucked air is urged to be under the action of centrifugal force The gas is directed in a centrifugal direction away from the rotating shaft 14 , so that the air flows against the inner wall of the fan casing 1 and flows out from the air outlet of the second casing 17 in the axial direction. Because there is a metal adsorption ring 11 on the inner wall close to it, the conductive metal is energized so that the adsorption ring 11 has an electrostatic adsorption effect on the dust. When the air with dust flows along the inner wall of the motor casing 1 to the adsorption ring 11, it will be adsorbed. On the adsorption ring 11, the dust removal shovel driven by the centrifugal impeller seat 10 shovels the dust accumulated on the adsorption ring 11 into the dust removal shovel. In particular, the dust removal shovel rocker arm 6 in the dust removal shovel is based on the rocker arm installation shaft 8 The fulcrum, when the thrust spring 7 pushes one end of the rocker arm, the dust inlet end of the shovel body 5 fixed at the other end is always attached to the adsorption ring 11 during the dynamic process, and the dust of the shovel body 5 that is shoveled in is received by the adsorption ring 11. The adsorption force is accumulated in the bottom rear end of the shovel body 5, so that the dust adsorbed on the adsorption ring 11 can be cleaned up in time, so that the adsorption ring 11 is always kept in a good clean state, and the adsorption capacity of the adsorption ring 11 is avoided from declining. When the fan stops, the motor base 3 and the motor base support arm 2 can be unloaded, and the accumulated dust can be cleaned up in time, thereby ensuring the cleaning of the motor 3 arranged at the rear end of the air outlet.
在特殊情况下，可以根据本实用新型的工作原理来收集空气中有用的微尘。In special cases, useful fine dust in the air can be collected according to the working principle of the utility model.
