BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a control module, and more particularly to a control module for a multi-nozzle shower to facilitate control of water being discharged from different nozzles. 
     2. Description of Related Art 
     Showers are implemented in spas, swimming pools, bathrooms, toilets and the like for cleaning a body. A conventional shower typically has one nozzle that sprays water down on the body and may be a fixed showerhead or a hand showerhead. 
     With technology developing, various types of showers including shower curtains, sensor-operated column showers and the like are provided. Many showers are provided with multiple nozzles that are separately arranged to spray different portions of the body for improved shower control. 
     Generally, the nozzles of a shower are respectively controlled by multiple faucets or switches being mounted respectively adjacent to the nozzles. Such that when operating the shower, people have to separately turn on and off the faucets or switches. This is confusing, inconvenient and requires improvement. 
     The present invention therefore provides a control module for a multi-nozzle shower to obviate or mitigate the aforementioned problems. 
     SUMMARY OF THE INVENTION 
     The main objective of the present invention is to provide a control module for a multi-nozzle shower that facilitates control of water discharge from different nozzles of a shower for greater convenience. 
     To achieve the objective, the control module for a multi-nozzle shower comprises a body, a control panel and a controlling assembly. The body is mounted securely in the shower and defines at least one chamber having multiple valve seats, at least one inlet and multiple outlets respectively communicating with the nozzles. The control panel is mounted securely on the body and seals the at least one chamber of the body. The controlling assembly is mounted in the control panel and has multiple valve disks and buttons. The valve disks selectively block the valve seats to stop water flow. The buttons are connected to the valve disks and are arranged on the control panel and selectively actuate the valve disks to block the valve seats. 
     Thereby, people can conveniently control water discharged from different nozzles or showerheads of the shower.

The buttons ( 63 ,  64 ,  73 ,  74 ,  83 ,  84 ) respectively correspond to two adjacent mounting holes in the sealing panels ( 41 ,  51 ) of the control panel ( 40 ) and each has a shaft having an end being mounted through a corresponding mounting hole of the control panel ( 40 ). The at least one valve disk ( 65 ,  75 ,  85 ,  86 ) is attached securely to the end of at least one shaft of the buttons ( 63 ,  64 ,  73 ,  74 ,  83 ,  84 ), and corresponds respectively to and selectively blocks the valve seats ( 241 ,  261 ,  331 ,  341 ) and may comprise an independent valve disk ( 65 ), an alternative valve disk ( 75 ) and two selector valve disks ( 86 ). The lever ( 61 ,  71 ,  81 ) is pivotally mounted in the control panel ( 40 ), has a central pin ( 62 ,  72 ,  82 ) that is selectively mounted pivotally in a corresponding lever mount ( 45 ,  54 ) of the control panel ( 40 ) and two ends that are pivotally connected respectively to the shafts of the buttons ( 63 ,  64 ,  73 ,  74 ,  83 ,  84 ), thereby the buttons ( 63 ,  64 ,  73 ,  74 ,  83 ,  84 ) perform contrary motion. 
     The inverter ( 90 ) comprises a sliding bar ( 94 ), an ancillary valve disk ( 93 ) and two couples ( 91 ). The sliding bar ( 94 ) is mounted slidably in the control panel ( 40 ), may be in the sealing panel ( 41 ) has an end and may be a shaft of the ancillary switch. The ancillary valve disk ( 93 ) is attached to the end of the sliding bar ( 94 ) and corresponds to one of the valve seats, may be to the ancillary valve seat ( 251 ). The couples ( 91 ) are respectively mounted pivotally in the grooves ( 28 ) of the main chamber ( 20 ) and have two ends pivotally connected respectively to the alternative valve disk ( 75 ) and the ancillary valve disk ( 93 ), thereby the valve disk ( 75 ) and the ancillary valve disk ( 93 ) perform contrary motion. 
     With further reference to  FIG. 4 , the control module in accordance with present invention may be mounted in a shower ( 1 ) with a cover ( 8 ) covering on the control module and allowing the buttons ( 63 ,  64 ,  73 ,  74 ,  83 ,  84 ) to selectively protrude out. The shower ( 1 ) has two showerheads ( 2 , 3 ) in a top of the shower ( 1 ), multiple body sprays ( 7 ) and a hand shower ( 5 ). The showerheads ( 2 ,  3 ) are respectively connected to the alternative connectors ( 17 ,  18 ) of the control module and may be alternately selected using the selector switch ( 80 ). The body sprays ( 7 ) are connected to the independent connector ( 14 ) and may be selectively turned on using the independent switch ( 70 ). The hand shower ( 5 ) comprises a flexible pipe ( 4 ) that is connected to the ancillary connector ( 15 ). The at least one inlet connector ( 13 ) is connected to a water supply pipe that may supply hot or cold water and may supply pressurized water. 
     When in use, pressing the buttons ( 63 ,  64 ,  73 ,  74 ,  83 ,  84 ) controls water discharged from the showerheads ( 2 ,  3 ), body sprays ( 7 ) and hand shower ( 5 ). With further reference to  FIGS. 7 and 8 , the independent switch ( 63 ,  64 ) is used to open and close the lower valve seat ( 241 ) via the independent valve disk ( 65 ). When open, the independent valve seat ( 241 ) allows water inside the first chamber ( 20 ) to flows through the independent outlet ( 14 ) and be discharged from the body sprays ( 7 ). 
     With further reference to  FIGS. 9 and 10 , since the independent valve disk ( 65 ) is independent, it may close or open the independent valve seat ( 241 ) in the following examples. 
     When the button ( 74 ) is actuated to close the alternative valve seat ( 261 ), the couples ( 91 ) open the ancillary valve disk ( 93 ) and the ancillary valve seat ( 251 ) is opened. Then the water inside the first chamber ( 20 ) flows through the ancillary output ( 25 ) through the ancillary connector ( 15 ) to be discharged from the hand shower ( 5 ). 
     With further reference to  FIGS. 11 and 12 , the button ( 73 ) can be pressed to open the alternative valve seat ( 261 ) and allows water in the first chamber ( 20 ) to flow into the second chamber ( 30 ) through the alternative output ( 26 ). 
     With further reference to  FIGS. 13 to 16 , the selector switch ( 80 ) is toggled to select the alternative connectors ( 17 ,  18 ) to discharge water through the showerheads ( 2 ,  3 ). 
     Therefore, by pressing different buttons ( 63 ,  64 ,  73 ,  74 ,  83 ,  84 ), the water being discharged from the showerheads ( 2 ,  3 ), the body sprays ( 7 ) and the hand shower ( 5 ) can be simply controlled.
