Further, the electronic switch is a movable relay.

Further, the number of the USB input interfaces is not less than 1.

Further, a camera is arranged on the outer surface of the shell and electrically connected with the controller.

Further, the data storage stores image information of authorized operators.

Further, still include the alarm, the alarm with the controller electricity is connected.

Further, the alarm comprises a warning lamp and/or a horn.

The embodiment of the utility model provides a have following advantage:

the utility model discloses a setting of USB input interface and USB output interface has set up a virus detecting system between USB flash disk and computer, avoids the USB flash disk to insert the direct contaminated computer of back virus, adopts the physics of confession electronic switch to block the form moreover, only judges qualified USB flash disk and just can link to each other with the computer, avoids the virus to skip and prevents the invasion device and directly influence the computer.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below. It should be apparent that the drawings in the following description are merely exemplary, and that other embodiments can be derived from the drawings provided by those of ordinary skill in the art without inventive effort.

Fig. 1 is a schematic structural diagram of an apparatus for preventing a virus from invading a computer according to an embodiment of the present invention.

Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Combine fig. 1 to show, the utility model discloses an avoid equipment of virus invasion computer, including casing 1, USB input interface 2, USB output interface 3, data memory 4, controller 5, electronic switch 6 and power 7, microprocessor is chooseed for use to controller 5, and external USB flash disk passes through USB input interface 2 and is connected with this equipment electricity, set up in the data of 1 inside controller 5 of casing in to the USB flash disk scan the discernment and with the virus storehouse of storage compares in the data memory 4, is provided with electronic switch 6 between controller 5 and the USB output interface 3, electronic switch 6 with controller 5 electricity is connected, USB output interface 3 links to each other with the computer. The utility model discloses a setting of USB input interface 2 and USB output interface 3 has set up a virus detecting system between USB flash disk and computer, avoids the USB flash disk to insert the direct contaminated computer of back virus, adopts the physics of supplying electronic switch 6 to block the form moreover, only judges qualified USB flash disk just can link to each other with the computer, avoids the virus to skip and prevents that the invasion device directly influences the computer. The electronic switch 6 adopts a movable relay, which can physically block and fundamentally avoid virus invasion in the USB flash disk.
