In the description of the present application, it is to be noted that, unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention, as those skilled in the art will recognize the specific meaning of the terms used in the present application in a particular context.
An embodiment of the present invention provides a fingerprint lock, and specifically, please refer to fig. 1, where fig. 1 is a schematic view illustrating a partial structure of a fingerprint lock in one embodiment, including: a lock body module 1, a protection module 2 and a data processing module 3 (for convenience of display, only the reference numbers and partial connection relations of some components are shown in the figure);
the lock body module 1 comprises a fingerprint reader 11, a lock body 12 and a lock body motor driving unit 13; the protection module 2 comprises a cleaning unit 21, an infrared sensor 22 and a cleaning driving unit 23;
the output end of the fingerprint input device 11 is connected with the data processing module 3; the lock body 12 is connected with the lock body motor driving unit 13;
the cleaning unit 21 is arranged on the contact surface of the fingerprint reader 11, and the cleaning unit 21 is connected with the cleaning driving unit 23;
the infrared sensor 22 is arranged on the contact surface of the fingerprint recorder 11, and the data output end of the infrared sensor 22 is connected with the data processing module 3;
the control end of the data processing module 3 is connected 23 with the lock body motor driving unit 13 and the cleaning driving unit, respectively.
It should be noted that, in the lock body module, the fingerprint reader is configured to receive external related signals, including a fingerprint input signal or a wake-up signal (preferably, a touch surface of the fingerprint reader is touched to generate a corresponding wake-up signal), and send the received signal to the data processing module for processing; the lock body motor driving unit is used for receiving related driving signals sent by the data processing module and driving the motor of the lock body to rotate, so that the fingerprint lock performs related operations of locking and unlocking; the cleaning driving unit is used for receiving the related driving signals sent by the data processing module and driving the cleaning unit to act, so that the cleaning work of the contact surface of the fingerprint recorder is realized, the fingerprint information and the stains on the surface are removed, the potential safety hazard is avoided, and meanwhile, the identification accuracy of the fingerprint lock can be improved; the infrared sensor is in communication connection with the data processing device and used for monitoring the cleaning effect, when the infrared sensor detects that the contact surface of the fingerprint recorder does not need to be cleaned, the infrared sensor can be in communication interaction with the data processing device, so that the data processing device stops generating a cleaning driving signal, the cleaning action of the cleaning unit is interrupted, and the purpose of saving energy consumption is achieved.
Preferably, in one of the embodiments, the fingerprint lock further comprises a timing module 4. The timing module 4 is connected with the data processing module 3, so that the data processing module 3 correspondingly controls the cleaning driving unit 23 according to the timing result of the timing module 4. The timing module can select a related timer to cooperate with the data processing module, and certainly, a data processing chip with a timing function can also be selected in the data processing module, so that the integration of the functions of data processing and timing is realized. Preferably, the timing module clears an internal timer before performing the cleaning operation to facilitate the next timing operation.
