DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
First of all, referring to FIGS. 2 through 4, a preferred embodiment of the invention includes a flexible conduit 60 and a showerhead main body 20.
The flexible conduit 60 has a head end 61 coupled to a water outlet 71 of a faucet 70. A first water supply channel 62 and a first water return channel 63 are fitted within the flexible conduit 60. The first water supply channel 62 is connected to the water outlet 71 of the faucet while the first water return channel 63 is provided with a back flow opening 64 extending outward near the head end 61.
The showerhead main body 20 includes a shank member 40 and a head member 30 at the top of the shank member 40.
The inside thereof is connected to each other. The bottom of the shank member 40 is attached to a tail end 65 of the flexible conduit 60. A second water supply channel 41 and a second water return channel 42 are fitted within the shank member 40 and communicated with the first water supply channel 62 and the first water return channel 63, respectively.
The head member 30 includes a first return flow chamber 31 that is connected to a third water supply channel 32 and a third water return channel 33. A blade wheel 34 is installed within the first return flow chamber 31. When the water flows from the third water supply channel 32 into the first return flow chamber 31 and comes out from the third water return channel 33, the blade wheel 34 will be rotated. Moreover, a shaft 35 of the blade wheel 34 protrudes out of the first return flow chamber 31 and brings a brush body 36 on the surface of the head member 30 into rotation. In other words, the brush body 36 is installed on a disc body 361. The bottom of the disc body 361 is attached to the shaft 35 of the blade wheel 34. A second return flow chamber 37 is disposed at the periphery of the first return flow chamber 31 and connected to a fourth water supply channel 38. A plurality of perforations 371 are formed at the surface thereof such that the water flowing into the second return flow chamber 37 is sprayed out of the perforations 371.
An adjustment knob 50 is interposed between the shank member 40 and the head member 30 and includes a rotation lug 51 and a stopper 52. As shown in FIG. 3, the rotation lug 51 for turning operation protrudes on the surface of the showerhead main body 20. As shown in FIGS. 4A and 4B, the stopper 52 for controlling the switching of the water flow channels is disposed within the showerhead main body 20. Meanwhile, the stopper 52 includes a plurality of connection channels 53 ̃56 at the side thereof. The connection channel 53 and the connection channel 54 are adapted to bring the second water supply channel 41 and the third water supply channel 32 in connection to the second water return channel 42 and the third water return channel 33, respectively.
The above-mentioned adjustment knob 50 is used to control the switching of the water flow channels within the showerhead main body 20. In other words, it permits the adjustment control of the use functions. According to this embodiment, only one adjustment knob 50 is employed for controlling. Alternatively, two or three adjustment knobs 50 can be used to control the water supply channels and the water return channels, respectively. However, one adjustment knob 50 is preferable for the use. Therefore, the stopper 52 of the adjustment knob 50 must have several perforated connection channels. In the first application state, the brush body 36 is moved by the shaft 35 when the blade wheel 34 is rotated (see FIG. 4). As shown in FIGS. 4A and 4B, the rotation lug 51 is in an upright position. In addition, the first connection channel 53 of the stopper 52 is connected to the second and third water supply channels 41, 32 while the second connection channels 54 is connected to the second and third water return channel in an ON state. As shown in FIG. 4B, the third and fourth connection channels 55, 56 are brought in a disconnected state (OFF). The connection channels 53 ̃56 are disposed in different position and height according to various requirements such that the adjustment knob 50 can control the required channel in an ON or OFF state when the adjustment knob 50 is turned to a predetermined position. According to the embodiment, the water coming from the faucet 70 flows through the water outlet 71 into the first water supply channel 62 of the flexible conduit 60. Thereafter, the water flows through the second water supply channel 41 of the shank member 40 into the first connection channel 53 of the stopper 52 and enters through the third water supply channel 32 into the first return flow chamber 31. By use of the water flow pressure, the blade wheel 34 will be rotated to bring the brush body 36 into autorotation. Moreover, the water flows from the third water return channel 33 via the second connection channels 54 and the second water return channel 42 into the first water return channel 63 and comes out of the back flow opening 64 into a bathtub 80. In this way, the water flow pressure may be employed for brushing the body of the operator by driving the brush body 36 to clean and massage the human body without any electric power supply. Meanwhile, the blade wheel 34 is driven to rotate the water to flow back to the bathtub 80 for further use.
FIGS. 5, 5A, and 5B illustrate a second application state of the invention. According thereto, the rotation lug 51 of the adjustment knob 50 is turned left at a certain angle such that the third connection channel 55 is brought in connection to the second water supply channel 41 and the fourth water supply channel 38. In this way, the water flows into the second return flow chamber 37 and is sprayed out of the perforations 371 for the user to take a shower.
FIGS. 6, 6A, and 6B illustrate a third application state of the invention. According thereto, the rotation lug 51 of the adjustment knob 50 is turned into a substantially horizontal position such that the fourth connection channel 56 of the stopper 52 is brought in connection to the second, third, and fourth water supply channels 41, 43, 38. In this way, the fourth connection channel 56 is formed in a substantially Y-shaped fork. Accordingly, the water flows into the first return flow chamber 31 and the second return flow chamber 37. Meanwhile, the second and third water return channels 42, 33 are connected to each other by the fifth connection channel 57. In this case, the showerhead of the invention can be used both to brush the body and to take a shower, thereby fulfilling a double function.
FIG. 7 illustrates another application example of the invention. The shank member 40 of the showerhead in accordance with the invention is longer than the conventional one. As a result, the user can take it to brush his back. It is an extra function that the conventional showerhead can't fulfill.
Many changes and modifications in the above-described embodiments of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
