Description

Dust removal device for display of all-in-one computer

Technical Field

The invention relates to the technical field of computer dust removal, in particular to a dust removal device for a display of a computer all-in-one machine.

Background

The computer all-in-one machine is a novel market product between a desktop computer and a notebook computer at present, and is a new computer integrating a host machine part and a display part together. The display of the computer all-in-one machine is exposed in the space for a long time, and the surface of the display has static electricity, so that dust is easily adsorbed to influence the watching experience. Therefore, after the all-in-one computer is used, the display of the all-in-one computer needs to be dedusted.

Generally, the dust removal of the all-in-one computer is manual operation, a user firstly erases the front of the display and then rotates the display to the back to erase the display, and the all-in-one computer is a highly integrated computer, so that vibration of parts of a main machine part in the computer is easily caused in the rotating process, and the use of the computer is influenced due to the damage of the computer. In order to solve the problem that the computer is damaged manually in the rotation process of the display, the other operation mode is that an operator erases the front of the display and then turns to the back of the display of the all-in-one computer to clean, if the space at the rear of the display is narrow, the operator can only bend from the top of the display to clean the back of the display, and the body of the operator can press the display to a certain extent invisibly, so that the display of the all-in-one computer is damaged.

In order to prevent the computer from being damaged by rotating the computer display, for example, the chinese patent application with application number 201810090743.0, entitled "a device for removing dust from the surface of an electronic display" discloses that when removing dust from an electronic display, a user first moves a first rubber pressing plate to the left and then places an electronic display screen between the first rubber pressing plate and a second rubber pressing plate. Although the disclosed patent can prevent the electronic display from rotating, the acting force between the first rubber pressing plate and the second rubber pressing plate acts on the electronic display screen, if the acting force between the first rubber pressing plate and the second rubber pressing plate is unequal, the electronic display screen can be inclined, and the electronic display screen can be seriously cracked.

In order to remove dust on the surface of a display, a cleaning device is generally arranged on the surface of the display, for example, chinese patent with application number 201510888009.5, entitled "computer display with dust removal function", discloses that sliding grooves are arranged on the upper and lower sides of a display screen of a display body, electric sliding blocks are arranged in the sliding grooves, a cleaning strip is arranged between the two electric sliding blocks, and the cleaning strip can move left and right along with the sliding of the electric sliding blocks.

In order to solve the technical problem that transverse scratches are easily formed only by transversely removing dust on a display screen, the Chinese patent application with the application number of 201810090743.0 and the name of 'an electronic display surface dust removing device' discloses that a gear and an electric rack are used for vertically removing, a screw rod rotates to drive a nut to transversely remove, although the disclosed patent cannot cause unidirectional scratches on the computer display screen, a wiping block and the rack of the disclosed patent are rigidly connected and easily generate rigid impact on the display screen.

The front surface of the display of the computer all-in-one machine is flat, the back surface of the display is uneven, and the computer display dust removal device in the prior art can only remove dust on the front surface and can not remove dust thoroughly on the uneven back surface.
