The brush 12 is held in the first assembly body 11 in a slidable manner, and has a plurality of bristles 121 on a tail end. By sliding the brush 12, the bristles 121 can be exposed outside the first assembly body 11 or held in the first assembly body 11. In an embodiment of the invention, the first assembly body 11 has a longitudinal slot 111 on one side. The slot 111 has a first retaining notch 112 and a second retaining notch 113 extended from two ends in a horizontal manner. The brush 12 has a sliding button 122 on one side corresponding to the slot 111 to be slid linearly in the slot 111. The sliding button 122 has a retaining lug 123 extended horizontally from two sides to be selectively latched on the first retaining notch 112 or the second retaining notch 113.
The second assembly body 13 may be coupled with the first assembly body 11 in a detachable manner. In an embodiment of the invention, the first and second assembly bodies 11 and 13 are coupled by screwing. The second assembly body 13 has a depressing element 131. The cleaner vial 14 is held in the second assembly body 13 and can be removed and replaced. In an embodiment of the invention, the cleaner vial 14 is inserted through the bottom of the second assembly body 13. After the first and second assembly bodies 11 and 13 are screwed together, the cleaner vial 14 is rested on a flat top end 114 of the first assembly body 11. The cleaner vial 14 has a nozzle 141 on the top end that is exposed outside the top end of the second assembly body 13. As the cleaner vial 14 is replaceable, when the cleaner (not shown in the drawings, being a liquid such as water, alcohol, or the like) is depleted, the cleaner vial 14 may be removed for replenishing the cleaner.
The third assembly body 15 is coupled with the second assembly body 13 in a detachable manner to cover the nozzle 141 of the cleaner vial 14. In an embodiment of the invention, the second assembly body 13 has a button hole 132 on one side close to the top end thereof. The third assembly body 15 has a pushbutton 151 on one side of a tail end thereof to be retained in the button hole 132 so that the second assembly body 13 and the third assembly body 15 can be coupled together. The wiping cloth 16 is held on the top end of the third assembly body 15 by wedging in a notch (not shown in the drawings) formed on the top end of the third assembly body 15. Hence the wiping cloth 16 can be replaced easily after being used for a period of time.
The cap 17 covers a front end of the third assembly body 15 to encase the wiping cloth 16. The cap 17 has a clip 171 on one side that has one end connecting to the cap 17 and another end extended to the third assembly body 15 to be in contact with the pushbutton 151 to serve as a releasing mechanism to separate the third assembly body 15 and the second assembly body 13.

In short, the invention couples a plurality of assembly bodies in a pen-like structure. Each of the assemblies holds a cleaning element of varying function. Users can hold and store the cleaning elements easily. By coupling the cleaning elements in an integrated manner, it can provide comprehensive cleaning functions. In addition, the composite cleaning device of the invention is not limited to cleaning computer screen and the peripheral devices (such as keyboards, mouse and the like). It also can be used on other small products such as GPS, PDAs, handsets, digital cameras, or lenses.
