In order to project and distinguish the hour hand 604a, the minute hand 604b and the second hand 604c, a pointer projection pattern 607a is arranged on the projection sheet 607, pointer projection patterns 607a with different shapes and colors are arranged, and pointer projections 608 formed are an hour hand projection 608a, a minute hand projection 608b and a second hand projection 608c respectively; a pointer light source is arranged right above the pointer part 603, the pointer light source forms a pointer projection 608 on a supporting surface through a pointer projection pattern 607a by means of light emitted by the pointer light source through refraction of the lens 305, and due to the replaceability of the projection piece 607, the pointer projection 608 can be replaced according to the requirements of users, so that individuation and interestingness of the intelligent night light are improved; when the intelligent night lamp is used, the user can read out the time information only by identifying the positions of the 3 pointer projections 608 on the supporting surface, and the setting meets the requirement that the user obtains specific time information, and provides different use experiences for the user, for example, different pointer projections 608 are provided for the user, so that different light atmospheres are created, and the interestingness and the practicability of the intelligent night lamp are increased; and pointer projection 608 can regard first scale facula 207b and second scale facula 209b as the reference, comes further to make the user more conveniently and clearly read out time information, has improved the accuracy to intelligent night-light reading information.

The dial 609 is detachably fixed on the clock base 60, the fourth installation groove 612 is formed by recessing a part of the clock base 60 downwards, the dial projection shell 610 is fixedly installed on the fourth installation groove 612 by adhesion, and certainly, the dial projection shell 610 can also be connected by screw thread connection, clamping and the like, the dial projection shell 610 is provided with a dial projection sheet 611, the dial projection sheet 611 is provided with textures such as ripples, magic colors, hammer marks and the like, light emitted by the needle light source passes through the dial projection sheet 611 and is projected on a supporting surface to form a dial projection 611a, the dial projection 611a is compared with the second scale light spot 209b, so that a user can replace the dial projection shell 610 according to requirements to project different projection dials 611a, thereby providing different light projection atmosphere effects, increasing interest and appreciation, and further enabling the user to read time information more conveniently, the practicality of intelligent night-light is improved. According to the clock base 60, the marks are arranged on the clock base 60, for example, the marks correspond to grooves or bulges of a clock large scale, so that a user can calibrate time information by using a reference object when adjusting the pointer part 603, and the accuracy of time is improved.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
