## Abstract

A decontamination apparatus for a viewing window includes a cylinder and a rotating module disposed at one end of the cylinder. The rotating module is connected with a viewing window. The rotating module can be driven to rotate, which further drives the viewing window to rotate for removing dirt attached to the viewing window. Besides, a decontamination apparatus for a viewing window includes a cylinder connected with a viewing window and a rotating module disposed at one end of the cylinder. The rotating module is connected with a wiper in contact with the viewing window. The rotating module can be driven to rotate, which further drives the wiper to turn for removing dirt attached to the viewing window.

## Claims

### Claim 1

A decontamination apparatus for a viewing window, comprising:
a cylinder; and
a rotating module, disposed at one end of the cylinder and connected with a viewing window;
wherein the rotating module can be driven to rotate, which further drives the viewing window to rotate for removing dirt attached to the viewing window, wherein the rotating module includes a rotor unit and at least one stator unit; the stator unit is fixed to an outer side of the cylinder and wound with an energizable coil; the rotor unit is pivotally connected to the cylinder, the viewing window is fixed on the rotor unit, and the rotor unit is provided with a permanent magnet opposite to the stator unit, wherein a bearing is provided between the rotor unit and the cylinder, and wherein the rotor unit includes a first block, a second block and a third block threadedly connected in sequence; the first block is connected with the bearing, the second block is connected with the permanent magnet, and the third block is connected with the viewing window; wherein the first block, the second block, and the third block are all formed as an annular shape, the bearing is socketed to the cylinder, the first block is rotatable relative to the cylinder via the bearing, the second block is threadedly connected on an upper end of the first block, the permanent magnet is attached on the side of the second block and is faced to the stator unit, the third block is threadedly connected on an upper end of the second block, the viewing window is socketed to the third block, therefore the second block and the third block are rotatable relative to the cylinder via the first block.

### Claim 2 (depends on 1)

The decontamination apparatus as claimed in claim 1, wherein a water drain gap is formed between the lens and a bottom end of the first block.
