Description

Water-saving showerhead that allows free use of both hands

The present invention relates to a water-saving showerhead in which both hands can be freely used, and more particularly, when washing a pet or infant by wearing it on the user's hand, the user's hands can be freely used while washing the hands. It relates to a water-saving showerhead that can be used freely.

In general, the shower head used in the shower is connected to a bellows hose of a certain length from the faucet.

In the shampoo pottery used mainly for washing hair, the hair is washed using the opening/closing lever attached to the faucet separately from the shower head as above. It is very inconvenient to do it.

Such a conventional shower generally washes the head or body while receiving water while hanging on a head hanger where the shower head can be hung. had to hold the shower head and control the direction of spraying water, so there was the inconvenience of washing infants or pets with only one hand.

In order to solve this inconvenience, various types of showerheads have been proposed that can be worn on the back of the hand to facilitate the supply of water while freely using both hands, but the conventional showerhead turns on/off the water supply to the showerhead itself. Since it does not include a valve structure that can do this, there was a lack of convenience in use for infants or companion animals.

The present invention was created to solve the above problems, and an object of the present invention is to provide a showerhead that can supply water while worn on the back of the hand so that the user can freely use both hands.
