Abstract: An atomizer includes a liquid storage shell, an ultrasonic atomizing core, a liquid transporting cotton, a cooling block, and an end cap. The liquid storage shell surrounds the liquid storage cavity and the functional cavity which are isolated from each other, wherein the liquid storage cavity is used for storing liquid. The ultrasonic atomizing core is assembled in the functional cavity. The liquid transporting cotton is connected to the ultrasonic atomizing core and inserted into the liquid storage cavity, so as to transport the liquid in the liquid storage cavity to the ultrasonic atomizing core. The cooling block is attached on one side of the ultrasonic atomizing core. The cooling block has an atomizing hole and an oil return hole. The end cap is connected to one end of the liquid storage shell to seal the liquid storage cavity and the functional cavity.

Abstract: Disclosed are a time calibration method and device. The method includes: a mobile terminal determines the local time where the mobile terminal is located according to the time data in a received GPS navigation message and time zone information about the mobile terminal (S102); and the mobile terminal performing time calibration on itself according to the local time where it is located (S104). The embodiments of the present disclosure can solve the problem that a mobile terminal cannot precisely adjust the time automatically if there is no accurate reference time or if there is no network coverage.
