A watering unit, it mounted under the fixed unit and comprises multiple watering sets which respectively communicate with the water outlets.
In a preferred embodiment: said switching unit further comprises a water division cover which is mounted under the supporting cover and disposed with multiple sets of water division holes which respectively communicate with the water outlets and watering sets.
In a preferred embodiment: said driving plate is disposed with a plurality of connection seats which are uniformly and circumferentially spaced, an opening slot is disposed on said connection seats; said sealing column comprises a rod, the outer rotating surface of said rod is fixed with a fixing plate and a sealing which are spaced up and down, said rod is connected inside the opening slot, said fixing plate and sealing clip the connection seat.
In a preferred embodiment: the bottom end of said rod is fixed with an intersectional plate unit, whose external diameter is adapted to the internal diameter of the water outlet.
In a preferred embodiment: a plurality of orientation slots are concave disposed under said main body, the top end of said rod is adapted to and slidably connected to the orientation slot.
In a preferred embodiment: the top end of said projecting part is disposed with a ball, the center of the bottom surface of said driving plate is concave disposed with a rotational slot, said rotational slot is adapted to the ball and connected together.
In a preferred embodiment: said fixed unit further comprises a handle which is fixed to the main body, said handle is hollow and communicates with the watering chamber and water supply.
In a preferred embodiment: said main body is disposed with a through step hole with a big bottom and a small top, said joystick stretches out of the step hole from inside to outside and a sealing ring is disposed between said step hole and joystick.
Compared to the background technique, the present invention applies the water division cover to cooperate with the driving plate for switching, thereby it can overcome the shortages of the background technique and it has such advantages: 1. the user only needs to rotate the joystick for switching, thereby it is convenient to switch; 2. because only the joystick is disposed outside of the shower, so it has a tidy appearance; 3. because only the joystick is disposed outside of the shower, so it only needs to seal the joystick and the shower to achieve a complete sealing effect, the sealing area will be small and the sealing requirement won't be too rigorous; 4. the switching structure is simple. The intersectional plate unit is not only used to open the water flow but also cooperate with the water outlet for orientating. The orientation slot slidably connected and adapted to the top end of the rod, so it can used for orientation. The rod is connected inside the opening slot, said fixing plate and sealing clip the connection seat, so the driving plate can be ensured to drive the sealing column to move up and down for precisely sealing or communicating. Because the driving plate and projecting part are connected by a ball, so it can be rotated omnidirectionally. Because a sealing ring is disposed between the step hole and rod, so the sealing effect is reliable, further the sealing ring has certain elasticity for providing certain space for the motion of the rod.
The present invention will become apparent upon the reference of the accompanying drawings and the description of the preferred embodiment.
