1. The interior of a traditional handicraft lantern cannot move. A less than satisfactory viewing effect makes it dull and reduces its decorative value as an ornamental handicraft.

2. Traditional handicraft lanterns contain some liquid, which will leak when the sealing is poor.

Thus, I have proposed the interior rotating structure of a handicraft lantern as a solution for the aforementioned problems.

Compared with prior craft, the benefits of this invention include the interior rotating lighting structure:

(1) A rotating gear and a shaft magnet are set on the motor interior, so that the rotating gear drives a large inner ring gear to spin through multi-step transmission of a reduction gear set. Moreover, the inner ring gear drives an impeller rotating bracket to rotate through the first magnets and second magnets, in such a way that the interior rotating bracket agitates the liquid when the central impeller revolves at the same time. At the same time, the shaft magnet on the motor shaft attracts the magnet impeller on the central impeller through the container sealing cover, whereby the central impeller rotates, enabling the central impeller to agitate the liquid in the transparent container. As a result, the impeller rotating bracket drives the interior rotating bracket to spin, so that the interior rotation of the lantern is realized and thereby improving the lantern's decorative value.

(2) The combination of the sealed rotary mechanism and container sealing cover makes the whole structure more water-tight. Moreover, mutual attraction between the first magnets and second magnets makes the inner ring gear rotate to drive the impeller rotating bracket, whereby the impeller rotating bracket further enables the interior rotating bracket to revolve. The shaft magnet and magnet impeller together drive the central impeller to rotate, preventing the motor shaft from directly driving the central impeller to revolve. This improves the sealing of the entire structure to avoid liquid leakage in the transparent container during rotation, and the device can be better used.

Specific Implementation Method

The invention will be described in detail with reference to the drawings and examples. It should be noted that the described examples are only a part of the invention. All other examples that technicians made without any creative efforts shall be included in the protection scope of the present invention.

As shown inFIGS. 1-7, the invention refers to an interior rotating structure of a handicraft lantern, comprising a lantern bracket1, a transparent container2, a sealed rotary mechanism3, a mounting frame4, a rear cover5, an interior rotating bracket6, a magnetic rotor7, a central impeller frame8, a container sealing cover9, a central impeller10, a motor shaft11, an inner ring gear12, a motor bracket13, a motor body14, a shaft magnet15, a magnet impeller16, an impeller rotating bracket17, a fixing rod18, an interior rotor19, a rotating gear20, a reduction gear set21, a transmission gear22, first magnets23, and second magnets24. The transparent container2is fixed under the lantern bracket1, the sealed rotary mechanism3is inserted under the transparent container2, the rear cover5is planted at the bottom end of the mounting frame4, the container sealing cover9is installed inside the sealed rotary mechanism3, and the central impeller10is mounted on the container sealing cover9. The central impeller frame8is installed on the exterior of the central impeller10, the interior rotating bracket6is planted on the outer side of the central impeller frame8, the magnet rotor7is built at the bottom end of the interior rotating bracket6, the motor shaft11penetrates the container sealing cover9, and the bottom end of the motor shaft11is connected to the output end of the motor body14through the motor bracket13. The shaft magnet15and rotating gear20are fixed on the outer side of the motor shaft11, the exterior of the rotating gear20is meshed and connected to the reduction gear set21, while the outer side of the reduction gear set21is meshed and connected to transmission gears22. The outer side of the transmission gears22is meshed and connected to the inner ring gear12, the first magnets23are fixed on the outer side of the inner ring gear12, and second magnets24are mounted on the outer side of the first magnets23. The impeller rotating bracket17is placed on the outer side of the second magnets24, while the interior rotating bracket6is inserted on the rear and outer sides of the impeller rotating bracket17. The rear side of the impeller rotating bracket17is connected to the central impeller10through the fixing rod18. The interior rotor19is fixed on the outer side of the interior rotating bracket6, and the magnet impeller16is set on the rear side of the impeller rotating bracket17.

The sealed rotary mechanism3is T-shaped and connected to the motor bracket13through screws, with the entire structure better sealed owing to the mutual cooperation between the sealed rotary mechanism3and the motor bracket13.

The interior rotating bracket6and sealed rotary mechanism3form a rotating structure through the fan-shaped magnetic rotor7, whereby the interior rotating bracket6can drive the interior rotor19to rotate and adjust the lantern's interior.

The container sealing cover9and sealed rotary mechanism3are integrated, with the container sealing cover9linked to the central impeller frame8, through a sliding connection, thereby improving the sealing performance of the container sealing cover9and sealed rotary mechanism3.

The central impeller10and central impeller frame8are configured to be detached through the fixing rod18, the vertical central line of the fixing rod18coincides with the vertical central line of the central impeller frame8, and the outermost sides of the central impeller10and the magnetic rotor7are not on the same plane. This way, the central impeller frame8can drive the central impeller10to rotate.

The inner ring gears12are equally distributed on the transmission gears22, and the inner ring gear12is fixed and connected to the impeller rotating bracket17through the first magnets23and the impeller rotating bracket17. When the transmission gears22rotate, it can drive the inner ring gear12to spin as well.

The impeller rotating bracket17forms a rotating structure through the sealed rotary mechanism3and inner ring gear12, the side of the impeller rotating bracket17is ring-shaped and connected to the interior rotating bracket6through welding, in which the inner ring gear12rotates and drives the impeller rotating bracket17to revolve.

The external diameter of each transmission gear22is larger than or equal to that of the reduction gear set21, with three transmission gears installed. Therefore, the transmission gears22can drive the inner ring gear12while rotating.

The first magnets23and second magnets24have different magnetic poles that make them attract. With the first magnets23and the second magnets24set this way, it facilitates the fixed rotation of the inner ring gear12and the impeller rotating bracket17.

The working principle of the example: When using the interior rotating structure of the handicraft lantern, as shown inFIG. 1-2, the motor bracket13and motor body14are installed with the sealed rotary mechanism3using an external mounting tool. After the installation, connect the motor body14to an external power supply so that the motor body14can drive the motor shaft11to rotate. The rotating gear20outside the motor shaft11as shown inFIG. 5drives the reduction gear set21to spin, and the rotation speed of the motor shaft11can be reduced by the rotation of the reduction gear set21. The reduction gear set21drives the transmission gears22to rotate. As such, the transmission gears22slowed by the reduction gear set21drives the inner ring gear12of the external meshing connection to rotate, as shown inFIG. 5.

The inner ring gear12drives the impeller rotating bracket17to rotate through the attraction of the first magnets23and second magnets24, so that the central impeller10inserted on the rear side of the impeller rotating bracket17spins through the fixing rod18. Meanwhile, the impeller rotating bracket17drives the interior rotating bracket6to move. When the motor shaft (11) rotates, the shaft magnet15attracts the impeller magnet16on the central impeller10through the container sealing cover9. The motor shaft can cause the central impeller10to rotate through the shaft magnet15and the impeller magnet16without directly coming into contact with the central impeller10. Therefore, the central impeller10not only agitates the liquid in the transparent container2, but also makes the liquid in the transparent container2flow. In addition, this results in the improved sealing performance of the entire rotating structure and the liquid in the transparent container2is prevented from leaking during the rotation.

The central impeller10can drive the central impeller frame8to rotate while the magnet impeller16on the central impeller frame8attracts the magnetic rotor7. The central impeller frame8drives the interior rotating bracket6to rotate through the magnetic rotor7, and the interior rotor19outside the interior rotating bracket6can rotate, causing the interior of the transparent container2to spin as well. Thus the rotating structure can operate normally in a well-sealed environment and rotate the liquid in the transparent container2. Moreover, the ornamental and decorative value of the handicraft lantern improved and a series of other functions is achieved.
