Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a shower device, and in particular to a modular structure shower device. 
         [0003]    2. The Prior Arts 
         [0004]    In general, for the bathing equipment utilized in a bathroom, such as, a shower or a shower head, its structure is rather fixed. For example, when using a shower, its shower face and shower handle are fixedly connected and can not be detached; and there are no water channels between the shower face and the base seat. As such, when the existing water channel of the shower is in fault, no water supply is available, such that the shower can not be used at all, thus causing inconvenience to the user. 
         [0005]    Therefore, presently, the design and performance of the shower device is not quite satisfactory, and it leaves much room for improvement.

         [0037]    The implementation of the present invention is described as follows: 
       Operation Principle (Solution  1 ) for the Condition that the Handle Set, the Hood Cover Set, and the Back Seat Set Are Assembled and Attached Together 
       [0038]    Water route  1 : water is input from the third water input port of the handle set. Due to the pushing force of the core axis, a movable seal rod is moved downward, to open the water output port. Then, the input water flows through inside the core axis toward the second check valve. Due to the pushing force of the input water, the second check valve is opened, so that water flows out from the hood cover. 
         [0039]    Water route  2 : water is input from the water input port of the ball head of the back seat set, the fastening claw pushes the third check valve to open, so that water can flow through the third check valve to the first check valve. Due to the pushing force of the input water, the first check valve is opened, so that water flows out from the hood cover. 
         [0040]    In the descriptions above, the water stop press button of the handle set is used to switch to open/close the water output hole of the handle set. 
       Operation Principle (Solution  2 ) for the Condition that the Handle Set, the Hood Cover Set Are Assembled and Attached Together, while the Back Seat Set is Detached 
       [0041]    Water route  1 : water is input from the third water input port of the handle set. Due to the pushing force of the core axis, a movable seal rod is moved downward, to open the water output port. Then, the input water flows through inside the core axis toward the second check valve. Due to the pushing force of the input water, the second check valve is opened, so that water flows out from the hood cover. Meanwhile, due to the action of the first check valve, water is not allowed to flow out from the back end face of the hood cover set. 
         [0042]    Water route  2 : water is input from the water input port of the ball head of the back seat set, due to the action of the third check valve, water is not allowed to flow out from the back seat set. 
         [0043]    In the descriptions above, the water stop press button of the handle set is used to switch to open/close the water output hole of the handle set. 
       Operation Principle (Solution  3 ) for the Condition that the Hood Cover Set and the Back Seat Set Are Assembled and Attached Together, while the Handle Set is Detached 
       [0044]    Water route  1 : water is input from the third water input port of the handle set, while the movable seal rod is in a seal state, so that water is not allowed to flow out form the end face of the handle set. 
         [0045]    Water route  2 : water is input from the water input port of the ball head of the back seat set, the fastening claw pushes the third check valve to open, so that water can flow through the third check valve to the first check valve. Due to the pushing force of the input water, the first check valve is opened, so that water flows out from the hood cover. Meanwhile, due to the action of the second check valve, water is not allowed to flow out from the lower end face of the hood cover set. 
         [0046]    In the descriptions above, the water stop press button of the handle set is used to switch to open/close the water output hole of the handle set. 
         [0047]    The above detailed description of the preferred embodiment is intended to describe more clearly the characteristics and spirit of the present invention. However, the preferred embodiments disclosed above are not intended to be any restrictions to the scope of the present invention. Conversely, its purpose is to include the various changes and equivalent arrangements which are within the scope of the appended claims.
