Specifically, as shown in fig. 5 to 7, a plurality of saw teeth are provided on the switching wheel 35, a plurality of external teeth are provided on the outer sleeve 32, each of the external teeth is provided with a first inclined surface 321, and a plurality of internal teeth are provided on the inner sleeve 33, each of the internal teeth is provided with a second inclined surface 331, and each of the saw teeth is provided with a third inclined surface 351.

Specifically, as shown in fig. 5 to 7, the pattern assembly 2 is rotatably mounted on the housing 1, and includes a supporting shell 21, a pressing plate 22 and a pattern plate layer 23, the pattern plate layer 23 is located between the supporting shell 21 and the pressing plate 22, and a plurality of projection holes 24 are opened on the supporting shell 21 and the pressing plate 22. The pattern sheet layer 23 is provided with a pattern at a position corresponding to the projection holes 24, and the luminous member 4 is positioned at a side of one of the projection holes 24.

The principle of the projection process is as follows: the light emitted from the light-emitting element 4 irradiates on the pattern in the projection hole 24, and the light is transmitted continuously and is projected on a plane through the projection lens 62 on the projection hole 61, and the pattern is displayed on the plane.

Specifically, as shown in fig. 8, a plurality of limiting holes 221 are formed in the pressing plate 22, a protrusion 341 is formed on the top of the top bar 34, and the protrusion 341 is embedded in the limiting holes 221. Thus, when the transmission rod 31 drives the push rod 34 to rotate, the push rod 34 drives the pattern assembly 2 to rotate, thereby realizing the switching of the patterns.

Specifically, when a pattern needs to be switched, the handle 36 is rotated, the transmission rod 31 moves forward, the outer gear sleeve 32 also moves forward, the third inclined surface 351 is arranged opposite to the first inclined surface 321, and when the outer gear sleeve 32 moves towards the direction of the switching wheel 35, the first inclined surface 321 is in contact with the third inclined surface 351, and after the outer gear sleeve 32 moves further, the first inclined surface 321 presses the third inclined surface 351, so that the switching wheel 35 is driven to rotate; the switching rotating wheel 35 is connected with the ejector rod 34 through a key, so that the ejector rod 34 synchronously rotates to drive the pattern component 2 to rotate; when the handle 36 continues to rotate, the transmission rod 31 moves backwards, the outer gear sleeve 32 resets, the inner teeth on the inner gear sleeve 33 are clamped between the two saw teeth on the switching wheel 35, the position of the ejector rod is fixed, and the pattern assembly is fixed. The handle 36 may be rotated once to switch the projection pattern.

Specifically, as shown in fig. 8, the zoom lens further includes a zoom lens assembly 5 installed in the housing 1, the zoom lens assembly 5 includes an adjusting gear 51, a rack 52 and a lens barrel 53 connected to the rack 52, a second lens 54 is fixedly installed at an end of the lens barrel 53, a knob 55 is connected to the adjusting gear 51, and the knob 55 is located outside the housing 1. In this way, the rotation knob 55 is rotated to drive the lens barrel 53 to move, so as to move the position of the second lens 54, thereby realizing the change of the relative position of the second lens 54 and the first lens 64, and realizing the adjustment of the focal length, when the size of the projection pattern of the device needs to be adjusted, the magnifying assembly 5 is operated. The lens barrel 53 is provided with a second lens 54 as a second viewing port at the end thereof where the user views the pattern.

In general, the magnifying assembly 5 cooperates with the first lens 64 to form a telescope, i.e. the first lens 64 is an objective lens, preferably a convex lens, and the second lens 54 is an eyepiece lens, preferably a concave lens; the distance between the first lens 64 and the second lens 54 changes the focal length, thereby realizing the change of the pattern size.

Specifically, the shell body 1 further comprises a bracket 7, and the shell body 1 is connected with the bracket 7 through a rotating shaft.

Specifically, the bracket 7 comprises a support table 71 and at least two support plates 72 hinged to the support table 71, and the height of the device can be adjusted by adjusting the angles of the support plates 72.

Specifically, the doll 8 is detachably mounted on the upper portion of the housing 1, and the speaker 9 is further mounted in the housing 1.

The working principle of the technical scheme is as follows: placing the favorite pattern plate 23 (i.e. the slide) between the support case 21 and the pressing plate 22, and irradiating the pattern on the projection hole 24 after the luminous element 4 is powered on, and projecting the pattern on a plane, such as a wall, through the projection lens 62; when the pattern needs to be switched, the handle 36 is rotated, the transmission rod 31 moves forward, and at this time, the first inclined surface 321 of the transmission rod presses the third inclined surface 351 for switching, so that the switching runner 35 is driven to rotate for a certain angle; because the switching rotating wheel 35 is connected with the top bar 34, the top bar 34 rotates synchronously, thereby driving the pattern component 2 to rotate for a certain angle, and switching to the next pattern can be realized.

The user can watch the pattern through the second lens 54, and when the size of the observed projection pattern needs to be adjusted, the magnifying component 5 can be operated; by rotating the knob 55, the lens barrel 53 is driven to move, so as to move the position of the second lens 54, thereby realizing the change of the relative position of the second lens 54 and the first lens 64.
