BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a tooth brush, and more particularly to a tooth brush having a rotary brush device and having a water jet for cleaning teeth. [0003] 2. Description of the Prior Art [0004] Various kinds of typical tooth brushes have been developed and comprise a brush device for brushing or cleaning teeth of users. For allowing the typical tooth brushes to easily brush or clean the teeth of the users, some of the typical tooth brushes provide a water spraying nozzle coupled to the brush device, for supplying water into the mouth of the users while conducting teeth brushing or cleaning operations. [0005] For example, U.S. Pat. No. 3,273,189 to Levinson et al., and U.S. Pat. No. 3,593,707 to Pifer disclose two of the typical tooth brushes and each also comprising a brush device for brushing or cleaning teeth of users, and each further comprising a water spraying nozzle coupled to the brush device, for supplying water into the mouth of the users while conducting teeth brushing or cleaning operations. However, the brush devices may not be rotated to brush or clean the teeth of the users. [0006] U.S. Pat. No. 3,927,434 to Burgess discloses another typical tooth brush comprising a pair of parallel rotary brushes synchronously driven by a fluid motor in opposite directions of rotation, to brush or clean the teeth of the users. However, no water may be supplied to clean the teeth of the users. [0007] U.S. Pat. No. 4,181,997 to O'Rourke discloses a further typical tooth brush comprising a brushing unit provided with rotating brushes, a dentifrice carrying cartridge attachable to a water faucet, and supporting an impeller operated by water pressure to rotate the brushes. The cartridge unit has a passage for conducting water from the faucet to the rotating brushes. [0008] However, the impeller is disposed far away from the rotating brushes of the brushing unit, and may not be used to directly or effectively rotate or drive the rotating brushes. [0009] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional tooth brush devices. SUMMARY OF THE INVENTION [0010] The primary objective of the present invention is to provide a tooth brush including a rotary brush device for suitably cleaning teeth of users. [0011] The other objective of the present invention is to provide a tooth brush including a water jet for spraying water and for suitably cleaning the teeth of the users. [0012] In accordance with one aspect of the invention, there is provided a tooth brush comprising a handle, a shank attached to the handle, and including a housing provided thereon, a casing disposed in the housing, a paddle wheel rotatably received in the casing, and including a shaft extended out of the casing, a rotary brush device attached to the shaft of the paddle wheel, and including a plurality of brush members provided on for teeth brushing purposes, and a water supplying device for supplying water into the casing, to drive and to rotate the paddle wheel relative to the casing, and to drive the brush members of the rotary brush device to brush teeth. [0013] The rotary brush device includes a base having a central hub provided thereon, and engaged onto the shaft of the paddle wheel, to attach the rotary brush device to the shaft of the paddle wheel. The shaft of the paddle wheel includes a peripheral groove formed therein, the rotary brush device includes at least one projection extended into the central hub thereof, to engage into the peripheral groove of the shaft of the paddle wheel, to attach the rotary brush device to the shaft of the paddle wheel. [0014] The rotary brush device includes an outer peripheral rim, and at least one bar coupled between the central hub and the outer peripheral rim, to form at least one opening in the base, and to allow water to flow through the opening of the base. The bar of the rotary brush device includes an inclined surface formed therein, and facing toward the paddle wheel. [0015] The casing includes a cover attached thereon, and having at least one orifice formed therein, for allowing water to flow out through the orifice of the cover and to flow onto the bar. [0016] The casing includes an inlet port directed toward an outer peripheral portion of the paddle wheel, to allow water to flow onto the outer peripheral portion of the paddle wheel, and to effectively rotate the paddle wheel relative to the casing. [0017] The water supplying device includes a water pump received in the handle, and coupled to the inlet port of the casing, to pump water into the inlet port of the casing. [0018] The housing includes a plate attached thereto and having a plurality of stationary brush members provided on, for teeth brushing purposes. The housing includes a recess formed therein, and a partition extended into the recess thereof, to form a peripheral shoulder in the housing, and to receive the plate. [0019] Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
