And a pressing spring 33 is arranged on the frame 7, the output end of the pressing spring 33 is propped against the rotary shifting block 31, and the elastic direction of the pressing spring faces the film disc 4. In the above technical solution, in order to ensure that the ratchet part 313 of the rotary shifting block 31 is well matched with the one-way ratchet wheel disc 14 on the back of the film disc 4, it is preferable that the ratchet part 313 and the one-way ratchet wheel disc 14 are tightly attached, and this solution can ensure that the two are tightly attached and the driving is more stable. Furthermore, the axial elastic compression also shows that the rotating shifting block 31 has an elastic adjusting space in the axial direction, so that on the basis of ensuring that the ratchet part 313 and the one-way ratchet wheel disc 14 are tightly attached, if the ratchet part 313 and the one-way ratchet wheel disc 14 rotate reversely, the unhooking and the unhooking recombination of the ratchet part 313 and the one-way ratchet wheel disc 14 can be realized. More importantly, because the film disc 4 is detachably inserted into the shell, when different stories are needed, the required film disc 4 is different, and therefore the film disc 4 has the requirement of frequent replacement. The rotation shifting block 31 has an elastic adjusting space in the axial direction, so that the unhooking and unhooking recombination of the ratchet part 313 and the one-way ratchet wheel disc 14 can be realized, and the film disc 4 is more convenient to disassemble and assemble.

In addition, the rotating shifting block 31 is further provided with a plurality of positioning grooves 314 or positioning holes along the circumferential direction, the number of the positioning grooves 314 or the number of the positioning holes is equal to that of the pictures on the film disc 4, the rack 7 comprises at least one elastic arm 73, the end part of the elastic arm 73 is provided with a positioning protrusion 731, the positioning protrusion 731 can extend into the positioning groove 314 or the positioning hole to circumferentially position the rotating shifting block 31, and when the rotating shifting block 31 is acted by the toggle gear 9, the positioning protrusion 731 can exit from the positioning groove 314 or the positioning hole. The above technical solution mentions that since the toggle gear 9 only drives one stopper 311 on the rotary dial 31 to move forward through the toggle arm 91 once, and the rotary dial 31 only rotates by one angle, one frame switching of the picture is realized. On the other hand, if the lever arm 91 is positioned on the frame 7 only by rotation, even if the stroke of the lever arm 91 acting on the rotary dial 31 is constant, when the lever arm 91 is separated from the rotary dial 31, the rotary dial 31 still has rotational inertia, and it is difficult to ensure a single rotation angle. In this embodiment, based on the cooperation between the positioning protrusion 731 of the elastic arm 73 and the positioning slot 314 or the positioning hole, when the shifting arm 91 is separated from the rotary shifting block 31, the positioning protrusion 731 extends into the positioning slot 314 or the positioning hole to realize positioning, so as to ensure a certain single rotation angle of the rotary shifting block 31.

The housing 7 is shown to include a base 71 and an end cap 72 attached to the base. The fixed end of the compression spring 33 abuts against the end cap 72, and the elastic arm 73 is also connected to the end cap 72.

Secondly, there is a difference between the manner of triggering the first travel switch 18 of the story small night light in this embodiment and that in example 2

As described above, in this embodiment, the rotating dial 31 replaces the swinging dial in embodiment 2, and the manner in which the film reel 4 is carried by the rotating dial is also changed. On the basis of this, the manner of activation of the first travel switch 18 also changes. In this embodiment, the first travel switch 18 is disposed inside the housing, and the rotation path of the toggle arm 91 on the toggle gear 9 passes through the trigger end of the first travel switch 18. When the toggle arm 91 of the toggle gear 9 triggers the first travel switch 18, the drive mechanism is intermittently stopped based on the trigger signal of the first travel switch 18. However, the reason for setting and the effect of triggering the first travel switch 18 are the same as those in embodiment 2, and the first travel switch 18 controls the motor to stop, thereby preventing the film on the film reel 4 from being continuously switched and allowing enough time for telling the story.

Thirdly, the night lamp assembly of the story small night lamp in the embodiment and the corresponding shell structure have differences

Specifically, the second light source 21 in this scheme is disposed at the open end of the tapered barrel 22, unlike the scheme in which the second light source 21 is disposed inside the tapered barrel 22 in embodiment 2. When the second light source 21 is disposed at the open end of the tapered cylinder 22, the tapered cylinder 22 has a weak light-gathering effect, and only the light from the second light source 21 toward the tapered cylinder 22 can be reflected and refracted. However, since the opening of the cone 22 faces the transparent region 23, the reflected and refracted light will also face the transparent region 23, thereby enhancing the projection effect of the transparent region 23.

On the basis, a partition plate 101 is transversely arranged inside the shell 1, and the partition plate 101 divides the inside of the shell 1 into an installation area 102 and a decoration area 105. The cone 22 is arranged in the mounting area 102 of the housing 1 with its open end in the decorative area 105. The second light source 21 is disposed at the open end of the cone 22, and at least the side wall constituting the decoration region 105 is a light-transmitting side wall. In a particular embodiment, the housing 1 includes a base 103 and a top cover 104, with the baffle 101 being between the base 103 and the top cover 104. The base 103 is a light-transmitting base.

In this embodiment, the interior of the housing 1 is divided into an installation area 102 and a decoration area 105 by the partition plate 101, and the housing 1 is also divided into a base 103 and a top cover 104 based on the partition plate 101, wherein the decoration area 105 is formed inside the base 103, and the installation area 102 is formed inside the top cover 104. The mounting area 102 is mainly used for mounting the mechanism in the small night lamp, so the projection window is arranged on the side wall of the mounting area 102 of the casing 1, and the first light source and the voice playing part are arranged in the mounting area 102 of the casing 1. The film reel 4 is removably inserted into the mounting area 102 of the housing 1.

The decoration area 105 is mainly used for decorating the outside by the projection of the second light source 21, so as to create an atmosphere effect.

The cone-shaped cylinder 22 in this embodiment is disposed in the mounting area 102 of the housing 1, but the open end is located in the decoration area 105, so that the cone-shaped cylinder 22 does not occupy the space of the decoration area 105 when being mounted, and can also perform a light-gathering effect on the second light source 21 in the decoration area 105. In addition, the second light source 21 in this scheme is disposed at the open end of the cone 22, the cone 22 does not have a large light-gathering constraint on the second light source 21, and at this time, the sidewall of the decoration region 105 is disposed as a light-transmitting sidewall, so that the decoration region 105 has a whole-body light-emitting effect, and the decoration effect is good. Of course, because of the function of the cone 22 and the light-transmitting pattern holes formed on the light-transmitting area 23, the stronger light is still directed toward the light-transmitting area 23, and the projection effect of the light-transmitting area 23 is enhanced.

On the basis of the above solution, the second light source 21 may be disposed on the partition 101, or the frame 7 in the housing 1 includes a mounting seat 74 disposed on the open end of the cone 22, and the second light source 21 is disposed on the mounting seat 74.

Also as described in embodiment 2, the control system calls up the audio content of the story stored by the film reel 44 based on the signal of the recognition means 6. Therefore, the night lamp related to the utility model is always provided with the voice playing part 35, and the control system calls the corresponding story audio content based on the information of the film disc 4 and plays the story audio content through the voice playing part 35. In this case, a through hole 221 is formed on the sidewall of the cone 22, and the playing direction of the voice playing part 35 faces the through hole 221 of the cone 22. The small night lamp can be hung for use according to the scheme, and patterns are projected from top to bottom. In cooperation with the above scheme, the voice playing part 35 (generally a loudspeaker) also plays sound downwards through the cone 22. In the process, the cone 22 performs a concentrated diffusion of the sound wave, similar to the function of a horn.
