The water intake connector is provided with a through water intake hole having a first flared portion at a rear end thereof, an outer threaded portion, and a stop rim behind the outer threaded portion. The ball valve seat includes a ball valve chamber, an inner stepped hole at a rear end of the ball valve chamber, and a connecting opening with an inner threaded portion at a front end of the ball valve chamber. The limiting seat includes a through communication hole with a second flared portion at a front end thereof, and an inner threaded portion at a rear end thereof. The water outlet seat is centrally provided with a through hole having a third flared portion at a front end thereof, an outer threaded portion near the front end of the water outlet seat, and a stop rim behind the outer threaded portion. When the inner threaded portion of the ball valve seat engages the outer threaded portion of the connector head of the water intake connector, the connecting opening of the ball valve seat will urge against the stop rim of the water intake connector and be positioned.
