Capacitive fingerprint identification device having drying function and capable of identifying accurately

Abstract

The present invention relates to a capacitive fingerprint identification device having a drying function and capable of identifying accurately. The capacitive fingerprint identification device comprises a shell, a drying mechanism is arranged on the shell, and a detection mechanism is arranged in the shell. The drying mechanism comprises an inner pipe, an outer pipe, an absorbent cotton and at least two installing assemblies, and the detection mechanism comprises an induction assembly, an extruding block, an identification window and two fastening assemblies. Each fastening assembly comprisesa fixing plate, a driving unit and a telescoping unit, and the telescoping unit comprises a fixing block, a moving block, a telescoping rack, a hinging block, a sliding ring, a sliding rail and a moving plate. The capacitive fingerprint identification device having the drying function and capable of identifying accurately absorbs the moisture on the fingers of the users via the absorbent cotton inthe drying mechanism, so that the fingers recover to be dry, and the device can identify conveniently and accurately. Moreover, the detection mechanism automatically identifies the fingerprints of the fingers of the users, during the identification process, users only need to insert the fingers, so that the fingerprint identification operation is simple and is convenient to execute, and the practicality of the device is improved.

Description

technical field [0001] The invention relates to the field of biometric identification equipment, in particular to a capacitive fingerprint identification equipment with drying function and accurate identification. Background technique [0002] With the advent of emerging technologies such as the mobile Internet and the Internet of Things, some traditional identification methods for people can no longer meet the needs of social development. Through the close combination of computer and high-tech means such as optics, acoustics, biosensors and biostatistics, the inherent physiological characteristics (such as fingerprints, facial images, irises, etc.) and behavioral characteristics (such as handwriting, voice, gait, etc.) of the human body are used. It has become a general trend to carry out personal identification. At present, the main biometric methods are: fingerprint recognition, palmprint recognition, face recognition, DNA recognition, behavior recognition, etc. At pres...

AI Technical Summary

Problems solved by technology

Since the capacitive fingerprint reader uses capacitance for fingerprint recognition, and water has conductive properties, the recognition ability of the reader is easily affected by the humidity of the finger, which makes the recognition difficult. Not only that, in the recognition process, the finger needs to follow the standard action Pressing on the identification window affects the user experience and reduces the practicability of existing capacitive fingerprint identification devices
