Fingerprint collection screen stain removal device

Abstract

The invention discloses a stain removal device for a fingerprint collection screen, comprising: a scrubbing mechanism, which is arranged on the left side of the fingerprint collection screen, and includes a first switch, a base, a rotating plate, a motor, a rotating shaft, and a scrubbing head, and a support is provided on the left side of the base The rod and the right side are provided with a first magnet, the left side of the rotating plate is hinged on the base, the inner surface of the right side is provided with a scrubbing head, the outer surface is provided with a pull rod and a second magnet, and the scrubbing head is columnar, including sequentially counterclockwise The dry part and the wet part with the same diameter and the same axial length are set, and the infusion mechanism is set on the left side of the scrubbing mechanism, including the first housing, the liquid storage bottle, and the output unit. When the rotating plate turns left to the end, The telescopic sleeve extends into the liquid inlet hole; the heating mechanism, which is arranged on the upper end of the fingerprint collection screen, includes a second switch, a second housing, a fan, and an electric heating element. The invention has the beneficial effects of removing stains, increasing the temperature of the fingerprint collection screen, and thus improving the identification ability of the fingerprint collection screen.

Description

technical field [0001] The invention relates to the technical field of fingerprint collection. More specifically, the present invention relates to a device for removing stains from a fingerprint collection screen. Background technique [0002] Fingerprint collectors are widely used in various places. Fingerprint recognition has some advantages, such as high accuracy, convenience and quickness. However, with the use of fingerprint collectors for a long time, the fingerprint collection screen will have problems of reduced recognition accuracy, such as dirt on the fingers. Or sweat stains are prone to identification failures, and repeated identification is required, or the fingerprint acquisition screen and the user's own fingerprints are wiped clean with hands or paper, which may damage the fingerprint acquisition screen, which is unhygienic and affects the identification efficiency. When your fingerprints are dry, it will also affect the recognition accuracy of the fingerpri...

[0002] Fingerprint collectors are widely used in various places. Fingerprint recognition has some advantages, such as high accuracy, convenience and quickness. However, with the use of fingerprint collectors for a long time, the fingerprint collection screen will have problems of reduced recognition accuracy, such as dirt on the fingers. Or sweat stains are prone to identification failures, and repeated identification is required, or the fingerprint acquisition screen and the user's own fingerprints are wiped clean with hands or paper, which may damage the fingerprint acquisition screen, which is unhygienic and affects the identification efficiency. When your fingerprints are dry, it will also affect the recognition accuracy of the fingerprint collection screen, and in the cold season of winter, due to the low temperature of the external environment, the temperature of the fingerprint collection screen is also low, and the fingerprint recognition ability will also be weakened.
