High-safety intelligent door lock

Abstract

The invention discloses a high-safety intelligent door lock. The high-safety intelligent door lock comprises a lock body, an outer panel and an inner panel; an electric bolt lock is installed in the lock body; 10 induction channels a leading to the front end face of the outer panel are arranged in the outer panel; the rear ends of the induction channels a are connected with a gas flow control assembly installed in a door body through hoses a correspondingly; the outer panel achieves non-contact type password inputting operation in the two manners of infrared photoelectric sensors and gas flowmatched gas pressure sensors; according to the situation whether the induction channels a have gas flow or not and the flowing direction of the gas flow, input passwords are dynamically adjusted, it is achieved that the same set password has different input values during each time of inputting, password leaking caused by malicious peeping can be effectively prevented, and the safety level of a password inputting device is improved on the basis of not remarkably improving the operation difficulty.
