Hand-held display screen cleaning device for automatic cloth changing and dosing

Abstract

The invention discloses a hand-held display screen cleaning device for automatic cloth changing and dosing. The hand-held display screen cleaning device comprises a main body box, a handle is fixedlyconnected with the lower end surface of the main body box, a sliding cavity with an upward opening is formed in the main body box, a rotating disc cavity is formed in the lower side of the sliding cavity in a communicating mode, a sliding box is slidably matched and connected within the sliding cavity, a front side transmission cavity located on the lower side of the sliding cavity is formed in the left side of the rotating disc cavity, and a first rotating shaft extending backwards into the front side transmission cavity is rotatably matched and connected within the front end wall of the front side transmission cavity. According to the hand-held display screen cleaning device, the sliding box is driven to reciprocate through a motor to complete cleaning and wiping of a display screen, andthe display screen is prevented from being damaged due to improper force control; and automatic cloth changing and automatic dosing can be completed by pulling a sliding plate, the damage of the display screen due to cloth hardening after long-term use of the same cloth for wiping is avoided accordingly, meanwhile, the amount of cleaning fluid is controlled, and the adverse effect on the cleaningeffect or the screen due to too much or too little cleaning fluid is avoided.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a hand-held display screen cleaning device for automatically changing cloth and adding medicine.
