Multi-power supply rotary projection music box

[0027] Example 1

[0028] see figure 1 and figure 2 , a kind of multi-power rotary projection music box of the present invention, comprises base 1, control unit 3 and the light source 8 that is connected with control unit 3, rotating mechanism 2 and sounding device 7, also includes the dry battery case that is connected with control unit 3 5. The solar photovoltaic cell 4 and the external power plug 6, wherein the rotating mechanism 2 includes a transparent cover 23 driven by a micro-motor 22 to rotate around a vertical line passing through the base 1, and a projection pattern 24 is arranged on the transparent cover 23, and a light source 8 Arranged in the transparent cover 23, the above-mentioned transparent cover 23 is a rotating body, and its cross section is preferably square or circular. Hollow groove, above-mentioned projection pattern 24 can be replaced.

[0029] In this embodiment, a solar cell mounting seat 41, a support rod 9 and a rotating mechanism 2 are sequentially arranged above the base 1, wherein a solar photovoltaic cell 4 is arranged on the outer surface of the solar cell mounting seat 41, and the upper surface of the solar cell mounting seat 41 is provided with There is a groove for accommodating the support rod 9. The support rod 9 is a hollow transparent structure to facilitate light transmission. The light source 8 is arranged on the bottom surface of the rotating mechanism 2. The rotating mechanism 2 includes a fixed bracket 21 at the top of the support rod 9 and a fixed bracket 21 Tightly connected micro motor 22 and transparent cover 23 connected to the shaft end of micro motor 22; above-mentioned transparent cover 23 includes a cover body 232 and a side wall 231, and the cover body 232 is provided with a groove at the center of the concave surface, and the groove passes through The adapter is connected to the rotating shaft of the micro motor 22, the top circumference of the transparent cover side wall 231 is movably connected to the edge of the cover 231, and the sound generating device 7 and the control unit 3 are arranged in the closed cavity formed by the base 1 and the solar cell mounting seat 4.

[0030] Based on the above structure, the operating principle of the multi-power rotary projection music box of the present invention is as follows:

[0031] In the case of sufficient sunshine, the music box is placed in a place where it can be exposed to sunlight, and the sunlight charges the solar photovoltaic cell 4 and stores the electric energy by the control unit 3. When the switch of the music box is turned on, the control unit 3 drives The micromotor 22 rotates at a constant speed, and the shaft end of the micromotor 22 drives the transparent cover body 232 and the transparent cover side wall 231 movably connected therewith to continue to rotate. The light emitted by the light source 8 forms various images when it is projected outward through the transparent cover 23 provided with the projection pattern 24. According to the difference of the projection pattern 24, the formed image can be flowers, snowflakes, Christmas ornaments, insects, animals, stars, precious stones, etc. Etc.; Sound generating device 7 works and plays music outwards, and the music played can also be selected as Christmas songs, dance music, piano music, etc.

[0032] The description of the function of each component in this embodiment is also applicable to other embodiments in this specification.

[0033] Example 2

[0034] The difference between this embodiment and implementation 1 is the overall structure of the multi-power supply rotary projection music box,

[0035] see image 3 , Figure 4 , the multi-power supply rotary projection music box in this embodiment includes a base 1-1, a control unit 3-1 and a light source 8 connected to the control unit 3-1, a rotating mechanism 2-1 and a sounding device 7-1, and also includes A dry battery box 5-1 connected to the control unit 3-1, a solar photovoltaic cell 4-1 and an external power plug 6, wherein the rotating mechanism 2-1 includes a plumb line that passes through the base 1-1 driven by a micro motor 22 The rotating transparent cover 23-1 is provided with a projection pattern 24-1 on the transparent cover 23-1, and the light source 8 is arranged in the transparent cover 23-1. The above-mentioned transparent cover 23-1 is a rotating body, and its cross section is preferably square or Circular, the projection pattern 24 is a color printing or silk screen pattern pasted on the transparent cover, or it can be a hollow groove arranged on the transparent cover 23-1, and the projection pattern 24 can be replaced; wherein the base 1-1 is provided with a There is a protrusion with a groove, the rotating shaft of the micro motor 22-1 is connected to the groove in rotation, the center position of the fixed bracket 1-1 is socketed with the micro motor 22-1 and a boss is provided at the edge, and the transparent cover 23 -1 is placed on the boss, the solar cell mounting seat 9-1 is arranged on the top of the transparent cover 23-1, the sounding device 7-1 and the control unit 3-1 are arranged in the solar cell mounting seat 9-1, and the light source 8 It is arranged at the bottom of the solar cell mounting base 9-1.

[0036] When the multi-power rotary projection music box described in this embodiment is working, its difference from Embodiment 1 is that in this embodiment, when the micro-motor 22-1 is working, its rotating shaft and the position of the base 1-1 remain stationary, The motor main body and the fixed support 21-1 that is socketed with the motor main body rotate at a constant speed to drive the transparent cover 23-1 and the solar cell mount 9-1 that is positioned at the top of the transparent cover to rotate.
