This invention relates to module applicable to a snow drop water ball structure, particularly to an impeller module driven by a magnetic power transmitted from the outside of the snow water ball.
Illustrated in
Conventional music snow drop ball is also well known in the art, including a driving mechanism for rotating a propeller placed in the water ball. The propeller rotates to drive up the snow drops in the water in accordance with the music emitted from a music bell. A shaft rod is passed through a shaft hole of a rotary tray of a base of the decoration. A clearance exists between the shaft rod and the shaft hole. Therefore, after a period of use, the water in the water ball tends to infiltrate back through the clearance into the driving mechanism. This will lead to rusting of the driving mechanism and affect the operation thereof.
U.S. Pat. No. 5,864,976 by Yang discloses a driving mechanism of music snow drop ball using an upper and lower silicone gaskets to prevent the water leaking from a shaft hole, so as to prevent the drawbacks which could caused by water leaking; however, when the gasket is fastened to bind the shaft rod, the friction between the shaft rod and the silicone gaskets may weakened the rotation of the shaft therein, so as causing the snow drops can be hardly driven up smoothly.
It is therefore a primary object of the present invention to provide a impeller module which could be driven by a magnetic power transmitted from the outside of the snow water ball, so that could provide waterproof effect and avoid outside driven mechanisms rusting.
According to the above object, the impeller module of music snow drop ball of the present invention includes an magnet driven impeller module which is attached on an anti-leak rubber plug for propelling the flow of the snow drops and rotation of the decoration in the glass dome. The magnet driven impeller module having a ring body provided with a magnetic part driven by a magnetic rotor from outside of the music snow drop ball to form as a magnetic couple, and receiving a rotational power to rotate a blade ring and a rotational disc thereof simultaneously, so as to function as a snow drop water ball and keep the anti-leak rubber plug therein as same as the conventional water ball structure to be integrally without making a shaft hole therein for outside driving mechanism, music bell, driving motor etc., so as to prevent water leaking problems.
The present invention can be best understood through the following description and accompanying drawings, wherein:

The decorations (40) and (41) illustrated above can be varied in different shaped and quantities according to the requirement of the manufacture in order to achieve the variation of the overall formation.
As shown in above illustrated, the magnet rotor (50) can be configured basically in a disc body shape coupled to and rotatable with a shaft which connect to music bell (60) or drive motor (70), and including a plurality of permanent magnetic (51) arranged in a circular array. Preferably, the disc body of the magnet rotor (50) may be made from polymeric, for example, polyolefin, such as polypropylene and the like, and encapsulates the circular array of permanent magnetic (51). The fabrication of the magnet rotor (50) provided can using various encapsulation techniques, many of which are well known and conventional in the art. Injection or insert molding may be employed to provide the magnet rotor (50).

The blade ring (6B20) comprising a ring body (6B21) having a spindle hole (6B23) for rotatably mounted on the bearing surface (6B12). A plurality of permanent magnets (6B22) connected to the ring body (6B21) and arranged in a circular array for receiving the rotational power with a magnetic coupling from the magnet rotor (50). A set of blades (6B24) extending radially from the periphery of ring body (6B21) for propelling and forcing the snow-like impurities flying over and over in the liquid of the snow drop ball.
The blade ring (6B20) having a inner gear (6B25) for meshing with the gear system (6B30) and transmitting the rotational power from the magnet rotor (50) to rotate the rotational disc (6B40).
The rotational disc (6B40) is rotatably supported by the central post (6B14), and having a gear portion (6B42) adapted to mesh with gear system (6B30). Therefore, when the magnet rotor (50) rotates, the ring body (6B21) and the rotational disc (6B40) will turn in different velocities and/or different directions, that would carry the blades (6B24) to fan up the snow-like impurities and rotate the decoration on the top of the rotational disc (6B40).
For enhancing the fan up effect, in a still further arrangement, the rotational disc (6B40) can further comprising a set of blades (6B43) extending radially from the periphery thereof, that would urge the flying of snow-like impurities more turbulently.

The blade ring (6C20) comprising a ring body (6C21) having a spindle hole (6C23) for rotatably mounted on bearing surface (6C12). A plurality of permanent magnets (6C22) connected to the ring body (6C21) and arranged in a circular array for receiving the rotational power with a magnetic coupling from the magnet rotor (50). A set of blades (6C24) extending radially from the periphery of ring body (6C21) for propelling and forcing the snow-like impurities flying over and over in the liquid of the snow drop ball.
The blade ring (6C20) having a inner gear (6C25) for meshing with the gear system (6C30) and transmitting the rotational power from the magnet rotor (50) to rotate the rotational disc (6C40).

Referring to
As can be understood from the above description, while a conventional water ball add the snow-like impurities and the impeller module (6A) according to the present invention, that would turn to be a snow drop water ball. Compare to the prior art, to use this invention, the anti-leak rubber plug no longer to need a shaft hole, so as to prevent liquid leakage from the glass dome and prolonging service life of snow drop water ball.
While the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications which may fall within the spirit and scope of the invention.
