Auxiliary device for fingerprint collector

Abstract

The invention discloses an auxiliary device for a fingerprint collector. The auxiliary device for the fingerprint collector is installed on a wall or a door body. The auxiliary device for the fingerprint collector comprises a cover body, a scrubbing mechanism, an infusion mechanism and a drying mechanism, wherein the cover body is arranged on a fingerprint collecting screen in a covering mode, a division plate is arranged in the cover body, and the cover body is divided into a first cavity at the left side and a second cavity at the right side through the division plate; the scrubbing mechanism is accommodated in the first cavity and comprises a motor, a connecting rod and a scrubbing plate, an absorbent cotton layer and a glass cloth layer are sequentially laid in the lower surface of the scrubbing plate, and an arc-shaped notch is formed in the right side face of the absorbent cotton layer; the infusion mechanism is accommodated in the second cavity and comprises a pressing rod, a liquid storing bottle and an output pipe; and the drying mechanism is arranged on the upper end face of the cover body and comprises a shell body and a fan which is accommodated in the shell body, wherein when the scrubbing plate is located at the starting point, the output pipe is arranged oppositely to the notch, the cover body is provided with a switch, the switch is electrically connected with a controller, and the controller is electrically connected with the motor and the fan. The auxiliary device for the fingerprint collector has the beneficial effects that the fingerprint collecting screen is automatically scrubbed and dried, and the recognition ability of the fingerprint collecting screen is improved.

Description

technical field [0001] The invention relates to the technical field of fingerprint collection. More specifically, the present invention relates to a fingerprint collector auxiliary device. 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 collection screen and the user's own fingerprints should be wiped clean with hands or paper. Due to the rough surface of the paper, it is likely to damage the fingerprint collection screen and affect the recognition ability of the fingerprint collection screen. , and when dry with one's own fingerprints.
