Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] see Figure 1-3 As shown, a general-purpose digital scanning head antifouling film includes a protective film 1, an adhesive layer 2 is bonded to the top of the protective film 1, a plastic film 3 is bonded to the top of the adhesive layer 2, and a plastic film 3 is bonded to the top of the plastic film 3. A dirt-repelling layer 4 is provided, and an adhesive layer 5 is bonded to the bottom of the protective film 1. The present invention achieves the pu...

Abstract

The invention relates to the technical field of electronic equipment protection, and discloses a universal dirt-avoiding film for a digital scanning head. The universal dirt-avoiding film comprises a protective film, wherein a bonding layer is bonded to the top of the protective film. According to the invention, a dirt-avoiding layer is arranged at the top of the protective film, so a dirt-avoiding purpose is achieved; when the digital scanning head is used, oil and water and finger marks can be prevented, the definition of the scanning head in the using process is guaranteed, and the situation that scanning is not clear is avoided; since the bonding layer and the digital scanning head are pasted, the purpose of preventing bubbles is achieved; and when an operator pastes a film on the digital scanning head, no bubble is generated between the bonding layer and the scanning head, the fitting degree between the scanning head and the protective film is increased to the maximum extent, and meanwhile, the phenomenon that the protective film is stuck by the operator due to the existence of bubbles and a new protective film needs to be used for bonding again is avoided, and therefore, use cost is further reduced.

Description

technical field [0001] The invention relates to the technical field of electronic equipment protection, in particular to a general-purpose antifouling film for a digital scanning head. Background technique [0002] A digital scanner is an automatic drawing input device that quickly converts graphics and images into digital forms by scanning methods based on the photoelectric principle. In order to prevent dirt from directly contacting the digital scanning head, a protective film is often pasted on the digital scanning head. [0003] However, the protective film used on the digital scanning head today cannot prevent contamination. Oil and water are easy to adhere to the protective film during use, and the operator's hand is in contact with the scanning head, and it will also leave dirt on the protective film of the scanning head. Finger marks, which will reduce the clarity of the scanning head when scanning, and then the scanning will not be clear, and in the long-term use of...
