BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a bathroom accessory, and more particularly to a shower head structure.

Description of the Prior Art

A conventional multifunctional shower head provides a variety of functional modes for the user to choose, such as, spraying shower water, bubble water, massage water, and so on. The shower head is provided with multiple diversion passages corresponding to multiple second functional water chambers and cooperating with a panel to achieve multiple functional modes. In general, the panel is rotated to switch the multiple functional modes. People need to operate the shower head with both hands for switching a desired functional mode. The operation is laborious and inconvenient. If the panel is non-circular, it is unable to rotate the panel for switching a desired functional mode. This multifunctional shower head only adjusts the way to spray water. As to a certain spray way, it is required to install a flow valve for the shower head to adjust the water intensity (that is, the flow rate). The existing shower heads do not have an adjustment structure able to adjust both the spray mode and the flow rate. This is inconvenient for use.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a shower head structure which is able to switch a different spray mode and control the amount of the water outflow of at least one water chamber to improve the functions of the shower head.

In order to achieve the aforesaid object, the shower head structure of the present invention comprises a housing and a panel to mate with each other. A middle of the panel is provided with a guide valve. A first functional water chamber is formed between the guide valve and the housing. An upper part of the guide valve is formed with a water inlet chamber. A lower part of the guide valve is formed with at least one second functional water chamber. A middle portion of the guide valve is formed with a transverse accommodation chamber. The accommodation chamber is provided with a water inlet communicating with the water inlet chamber, a first water discharge passage communicating with the first functional water chamber, and a second water discharge passage communicating with the second functional water chamber. A rotary shaft is provided in the accommodation chamber. The rotary shaft is rotatable for controlling the first water discharge passage to communicate with the second water discharge passage. The housing is provided with a handle connected to one end of the rotary shaft. An outlet of the first functional water chamber is provided with a control valve. An outer wall of the guide valve is provided with a piston fixedly connected to the control valve. Another end of the rotary shaft extends outward to form an eccentric connecting rod. The eccentric connecting rod is connected with the piston so that the rotary shaft is rotated to drive the piston to move up and down.

Preferably, the rotary shaft is a hollow structure. The rotary shaft has a passage therein. An outer wall of the rotary shaft is formed with an annular groove. A chamber is formed between the annular groove and an inner wall of the accommodation chamber. The first discharge passage communicates with the chamber. The annular groove is fitted with a stopper. The stopper is movable to block the first water discharge passage. The rotary shaft is formed with at least one aperture for the passage to communicate with the chamber. The rotary shaft further has a through hole communicating with the passage. The through hole is configured to communicate with the second water discharge passage.

Preferably, the first water discharge passage is perpendicular to the second water discharge passage, and the stopper is perpendicular to the through hole.

Preferably, an O-shaped ring is provided between the rotary shaft and the accommodation chamber.

Preferably, the second discharge passage is fitted with a sealing ring on an opening in contact with the rotary shaft.

Preferably, the first functional water chamber is a shower water chamber, and the second functional water chamber is a massage water chamber.

The rotation of the rotary shaft of the present invention controls the communication state of the first water outlet passage and the second water discharge passage for controlling the first functional water chamber and the second functional water chamber to discharge water or not, thereby switching the outflow mode. Through the eccentric connecting rod to move the piston up and down, the water intensity of the first functional water chamber can be changed, enhancing the functions of the shower head.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown inFIG. 1toFIG. 9, the present invention discloses a shower head structure. The shower head structure comprises a housing A and a panel B to mate with each other. The middle of the panel B is provided with a guide valve C. A first functional water chamber1is formed between the guide valve C and the housing A. An upper part of the guide valve C is formed with a water inlet chamber2. A lower part of the guide valve C is formed with at least one second functional water chamber3. A middle portion of the guide valve C is formed with a transverse accommodation chamber4.

The accommodation chamber4is provided with a water inlet41communicating with the water inlet chamber2, a first water discharge passage42communicating with the first functional water chamber1, and a second water discharge passage43communicating with the second functional water chamber3. A rotary shaft5is provided in the accommodation chamber4. The housing A is provided with a handle6connected to one end of the rotary shaft5. The rotary shaft5is controlled and rotated by turning the handle6. The rotary shaft5is rotated for controlling the first water discharge passage42to communicate with the second water discharge passage43.

An outlet of the first functional water chamber1is provided with a control valve11. An outer wall of the guide valve C is provided with a piston7fixedly connected to the control valve11. Another end of the rotary shaft5extends outward to form an eccentric connecting rod8. The eccentric connecting rod8is connected with the piston7so that the rotary shaft5is rotated to drive the piston7to move up and down to compress the control valve11or to pull the control valve11for changing the water intensity of the first functional water chamber1.

Specifically, the rotary shaft5is a hollow structure. The rotary shaft5has a passage51therein. An O-shaped ring a is provided between the rotary shaft5and the accommodation chamber4to ensure the airtightness. An outer wall of the rotary shaft5is formed with an annular groove52. A chamber is formed between the annular groove52and an inner wall of the accommodation chamber4. The first discharge passage42communicates with the chamber. The annular groove53is fitted with a stopper53. The stopper53is movable to block the first water discharge passage42. The rotary shaft5is formed with at least one aperture521for the passage51to communicate with the chamber. The rotary shaft5further has a through hole54communicating with the passage51. The through hole54is configured to communicate with the second water discharge passage43. The second discharge passage43is fitted with a sealing ring b on an opening in contact with the rotary shaft5to ensure the airtightness between the rotary shaft5and the second discharge passage43.

In the normal state of the present invention, the first functional water chamber1is opened to discharge water and the second functional water chamber3is closed. When the rotary shaft5is rotated by the handle6, the rotary shaft5drives the piston7to move up and down to change the water intensity of the first functional water chamber1. The first water discharge passage42can be blocked by the stopper53when the rotary shaft5is turned to a predetermined angle. When the through hole54is aligned with the second water discharge passage43, the second functional water chamber3is opened to discharge water for switching the spray mode.

Preferably, the first functional water chamber1is a shower water chamber. The second functional water chamber3is a massage water chamber. The first water discharge passage42is perpendicular to the second water discharge passage43. The stopper53is perpendicular to the through hole54. The first water discharge passage42and the second discharge passage43occupy an angle of 100° in the circular cross section of the accommodation chamber4, respectively. Therefore, when the present invention is used, as shown inFIG. 1toFIG. 3, when the water intensity of the shower water chamber is the maximum and the massage water chamber is closed, and the handle6is turned by 0°. When the handle6is turned by 40° to 220°, the stopper53does not block the first water discharge passage42, and the through hole54is not aligned with the second water discharge passage43, and the rotary shaft5is rotated to drive the piston7to move up and down for changing the water intensity of the shower water chamber. When the handle6is turned by 180°, the water intensity of the shower water chamber is the minimum. When the handle6is turned by 220°-270°, the stopper53partially blocks the first water discharge passage42, and the through hole54is partially aligned with the second water discharge passage43. Both the massage water chamber and the shower water chamber are opened to discharge water, namely, in a mixed outflow state. The rotary shaft5is rotated to drive the piston7to move up and down for changing the water intensity of the shower water chamber. As shown inFIG. 4toFIG. 6, when the handle6is turned by 270°, the stopper53completely closes the first water discharge passage42, and the through hole54is completely aligned with the second water discharge passage43. Only the massage water chamber is opened to discharge water, and the shower water chamber is closed. When the handle6is turned by 270°-320°, as shown inFIG. 7toFIG. 9, the stopper53partially blocks the first water discharge passage42, and the through hole54is partially aligned with the second water discharge passage43. Both the massage water chamber and the shower water chamber are opened to discharge water. The rotary shaft5is rotated to drive the piston7to move up and down for changing the water intensity of the shower water chamber. At this time, the shower head is in a mixed outflow state.

As described above, the rotation of the rotary shaft5of the present invention controls the communication state of the first water outlet passage42and the second water discharge passage43for controlling the first functional water chamber1and the second functional water chamber3to discharge water or not, thereby switching the outflow mode. Through the eccentric connecting rod8to move the piston7up and down, the water intensity of the first functional water chamber1can be changed, enhancing the functions of the shower head.
