When the alarm is started, a beep of beep is generated, the alarm symbol flickers, and at the same time, any key is pressed to stop ringing and the alarm icon stops flickering; if no key operation sounds for 1 minute, the snooze is automatically carried out for 10 minutes, the snooze can be closed by pressing any key in the snooze time keeping process, the alarm sounds again after the snooze time keeping process is finished, and the alarm is closed by pressing any key.

The setting of little night-light: the small night lamp can be turned on/off by pressing the lamp on/off key for a short time, and after the small night lamp is turned on, the small night lamp can be subjected to electrodeless dimming by pressing the lamp on/off key for a long time.

The function of accompanying sleep: and the sleep accompanying function is entered by pressing the sleep accompanying key for 2 seconds. And finally, after the sleep key is pressed for a long time, the light of the small night lamp is gradually darkened, and the small night lamp is turned off after 30 minutes. After the sleep accompanying function is started, the light of the small night lamp flickers for 2 times, and the sleep accompanying function icon is lightened.

A power saving mode; the method comprises the following steps that a key is pressed for a short time to enter a power saving mode, after the key enters the power saving mode, a digital display screen is turned off, and at the moment, a small night lamp is turned on to obtain the lowest brightness; and the sleep accompanying key is pressed for a short time again to exit the power saving mode, the digital display screen is lightened, and the small night lamp is turned on to obtain the default maximum brightness.

A digital display screen: the digital display screen normally only displays 'year-month-day' in a circulating way. When the alarm clock with the date is set, the alarm clock with the corresponding date and time is displayed.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same way in the protection scope of the present invention.
