Brush device

Abstract

A brush device includes a housing having an exit end, an entrance end, and a room defined in the housing. A propeller unit is located in the room and includes a shaft with multiple first blades on an outside thereof. The shaft includes a driving head extending through the exit end of the housing. The driving head is connected with a brush so that the brush is rotated by water entering from the entrance and exiting from the exit end.

What is claimed is: 
     
         1 . A brush device comprising:
 a housing having an exit end and an entrance end, a room defined in the housing and communicating with the exit end and the entrance end, the exit end including a through hole and multiple first bores, the entrance end includes a second bore which communicates with the first bores, and   a propeller unit having a shaft and multiple first blades, the shaft including a body and a driving head on one end of the body, the body located within the room, the multiple first blades located on outside of the body, the driving head extending through the through hole and connected with a brush, the brush being adapted to be rotated by water entering from the entrance and exiting from the exit end.   
     
     
         2 . The brush device as claimed in  claim 1 , wherein the propeller unit includes at least one first part which includes a first tube, the first tube includes a first passage defined axially therethrough, the body of the shaft co-rotatably extends through the first passage, the first blades are located on an outside of the first tube. 
     
     
         3 . The brush device as claimed in  claim 2 , wherein the body of the shaft includes multiple ribs extending axially from an outside thereof, the first tube includes multiple first ridges protruding axially from the outside thereof, each of the first ridges defines a first groove formed axially in an inside of the first tube, the ribs of the body are engaged with the first grooves. 
     
     
         4 . The brush device as claimed in  claim 3 , wherein the propeller unit includes at least one second part which includes a second tube, the second tube includes a second passage defined axially therethrough, the body of the shaft co-rotatably extends through the second passage, multiple second blades are located on an outside of the second tube, the second tube includes multiple second ridges protruding axially from the outside thereof, each of the second ridges defines a second groove formed axially in an inside of the second tube, the ribs of the body are engaged with the second grooves. 
     
     
         5 . The brush device as claimed in  claim 4 , wherein the first and second blades are located along the body of the shaft and located alternatively to each other. 
     
     
         6 . The brush device as claimed in  claim 1 , wherein a connector  5  includes a first connection hole defined in a first end thereof, the entrance end of the housing is connected to the first connection hole, a handle has a first end thereof pivotably connected to a second end of the connector, a second connection hole is defined in a second end of the handle so as to be connected with a water source, the handle includes an adjustment member which is adapted to adjust water volume from the second connection hole to the first connection hole. 
     
     
         7 . The brush device as claimed in  claim 1 , wherein the brush includes a connection hole defined in one end thereof, the driving head of the shaft is securely engaged with the connection hole. 
     
     
         8 . The brush device as claimed in  claim 1 , wherein a washer is mounted to the driving head and located between the body of the shaft and an inside of the exit end.
