DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0012] Referring to FIGS. 1 to 6, the brush device of the present invention comprises a housing 1 having an exit end 12 and an entrance end 15 respectively formed on two ends thereof. A room 11 is defined in the housing 1 and communicates with the exit end 12 and the entrance end 15. The exit end 12 includes a through hole 122 and multiple first bores 121 which are located around the through hole 122. The entrance end 15 includes a second bore 151 which communicates with the first bores 121.

[0013] A propeller unit 2 located in the room 11 and includes a shaft 21, and at least one first part 22 and at least one second part 23 are mounted to the shaft 21. The shaft 21 including a body 212 and a driving head 211 on one end of the body 212. The body 212 located within the room 11, and the driving head 211 is a rectangular head that extends through the through hole 122 and connected with a brush 4. Specifically, the brush 4 includes a connection hole 42 defined in one end thereof as shown in FIG. 2, and the driving head 211 of the shaft 21 is securely engaged with the connection hole 42. The body 212 of the shaft 21 includes multiple ribs 213 extending axially from the outside thereof.

[0014] The at least one first part 22 includes a first tube 221 which includes a first passage 223 defined axially therethrough. The first tube 221 includes multiple first ridges 225 protruding axially from the outside thereof. Each of the first ridges 225 defines a first groove 224 formed axially in the inside of the first tube 221. The body 212 of the shaft 21 co-rotatably extends through the first passage 223 and the ribs 213 of the body 22 are engaged with the first grooves 224. Multiple first blades 222 are located on the outside of the first tube 221.

[0015] Similarly, the at least one second part 23 includes a second tube 231 which includes a second passage 233 defined axially therethrough. The second tube 231 includes multiple second ridges 235 protruding axially from the outside thereof. Each of the second ridges 235 defines a second groove 234 formed axially in the inside of the second tube 231. The body 212 of the shaft 21 co-rotatably extends through the second passage 233 and the ribs 213 of the body 22 are engaged with the second grooves 234. Multiple second blades 232 are located on the outside of the second tube 231. The first and second blades 222, 232 are located along the body 212 of the shaft 21 and located alternatively to each other as shown in FIG. 4.

[0016] As shown in FIGS. 5 and 6, a connector 5 includes a first connection hole 51 defined in the first end thereof, and the entrance end 15 of the housing 1 is connected to the first connection hole 51. A handle 6 has the first end thereof pivotably connected to the second end of the connector 5. A second connection hole 61 is defined in the second end of the handle 6 so as to be connected with a water source such as a water hose (not shown). The first and second connection holes 51, 61 communicate with each other. The handle 6 further includes an adjustment member 62 which is cooperated with a valve (not shown) in the handle to adjust water volume that enters from the second connection hole 61 and exits from the first connection hole 51. A washer 3 is mounted to the driving head 211 and located between the body 212 of the shaft 21 and the inside of the exit end 12. Therefore, the body 212 of the shaft 21 does not directly contact the inside of the exit end 12 to enhance rotation of the shaft 21. A locking member 7 connects the housing 1 to the connector 5. The housing 1 and the brush 4 are pivotable relative to the handle 6 by the connector 5.

[0017] As shown in FIG. 3, water 8 flows from the second connection hole 61 of the handle 6 and enters into the entrance end 15 via the first connection hole 51 of the connector 5. The water 8 drive the first and second blades 222, 232 so that the shaft 21 are rotated by the rotation of the first and second blades 222, 232. The driving head 211 is connected to the brush 4 so as to rotate the brush 4. The bristle 41 on the rotational brush 4 effectively clean objects. The brush 4 can be easily replaced simply by pulling the brush 4 from the driving head 211.

[0018] The brush 4 is rotated by water flow and no electric power needed.

[0019] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
