Abstract
A hand shower and base showerhead with water flow switching mechanism in which a movable flow switching magnet movable between a hand shower flow permitting position and a base showerhead flow permitting position is used to magnetically act on the magnetic hand shower flow control assembly and the magnetic base showerhead flow control assembly to achieve automatic switching of water flow from the hand shower to the base showerhead and vice versa.
Claims10
Hand shower and base showerhead with water flow switching mechanism which comprises
- a hand shower having a hand shower head provided with a hand shower inlet and a hand shower outlet, and a hand shower handle which fluidly communicates with the hand shower inlet and a water source;
- a magnetic hand shower flow control assembly movably disposed inside the hand shower head and is axially movable between a hand shower non-blocking position which allows water flow between the hand shower inlet and the hand shower outlet and a hand shower blocking position which blocks water flow between the hand shower inlet and the hand shower outlet;
- the hand shower flow control assembly is biased towards the hand shower blocking position;
- a base showerhead having a base showerhead inlet which fluidly communicates with the water source, a base showerhead outlet and a receiving recess for removably receiving the hand shower head;
- a magnetic base showerhead flow control assembly movably disposed inside the base showerhead and axially aligned with the hand shower flow control assembly when the hand shower head is received in the receiving recessing;
- the base showerhead flow control assembly is axially movable between a base showerhead non-blocking position which allows water flow between the base showerhead inlet and the base showerhead outlet and a base showerhead blocking position which blocks water flow between the base showerhead inlet and the base showerhead outlet;
- the base showerhead flow control assembly is biased towards the base showerhead blocking position;
- a movable flow switching magnet disposed inside the hand shower head and axially aligned with the hand shower flow control assembly;
- the movable flow switching magnet is axially movable between a hand shower flow permitting position and a base showerhead flow permitting position, and is biased towards the hand shower flow permitting position;
- the movable flow switching magnet is configured to have a magnetic force strong enough to attract the hand shower flow control assembly for the hand shower flow control assembly to overcome its biasing force to move to the hand shower non-blocking position when the hand shower is removed from the receiving recess of the base showerhead and the movable flow switching magnet is biased to the hand shower flow permitting position;
- the base showerhead flow control assembly is configured to have a magnetic force strong enough for the base showerhead flow control assembly and the movable flow switching magnet to overcome their respective biasing forces to move towards each other and thereby moving the movable flow switching magnet to the base showerhead flow permitting position and the base showerhead flow control assembly to the base showerhead non-blocking position when the hand shower head is received in the receiving recess of the base showerhead and the hand shower flow control assembly is biased to the hand shower blocking position as the magnetic force of the movable flow switching magnet is not strong enough to attract the hand shower flow control assembly to overcome its biasing force when it is moved to the base showerhead flow permitting position.
