Fingerprint collection screen stain removing device

Abstract

The invention discloses a fingerprint collection screen stain removing device. The device comprises a scrubbing mechanism, a liquid conveying mechanism, and a heating mechanism. The scrubbing mechanism is arranged on the left of a fingerprint collection screen and comprises a first switch, a base, a rotating plate, a motor, a rotating shaft, and a scrubbing head. The left side of the base is provided with a support rod, and the right side of the base is provided with a first magnet. The left side of the rotating plate is hinged to the base, the scrubbing head is arranged on the inner surface of the right side, and a pull rod and a second magnet are arranged on the outer surface. The scrubbing head is of a column shape and comprises a drying part and a wetting part which are sequentially arranged in an anticlockwise direction and have the equal diameter and equal axial length. The liquid conveying mechanism is arranged on the left side of the scrubbing mechanism and comprises a first shell, a liquid storage bottle, and an output unit. When the rotating plate turns left to an end point, a telescopic tube extends into a liquid inlet. The heating mechanism is arranged at the upper end of the fingerprint collection screen and comprises a second switch, a second shell, a fan, and an electric heating element. The device has the advantages of removing stains, increasing the temperature of the fingerprint collection screen, and accordingly improving the recognition capability 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.
