Abstract:
1. A movable spread head comprising: a tubular member including a channel, an inlet and an outlet, both of which are disposed on two ends of the channel respectively; the inlet coupled with a soft pipe in a water tap, the channel including a large diameter first passageway and a small diameter second passageway, and on an outer side of the first passageway being formed the inlet, on an outer side of the second passageway being formed the outlet; the tubular member also including an insulation rim extending on a peripheral wall of the outlet, the second passageway defined between a lower side of the insulation rim and the peripheral wall; the tubular member including an opening mounted on the peripheral wall above an upper side of the insulation rim so that a receiving groove is defined between the opening and the upper side of the insulation rim, and between the upper side of the insulation rim and the peripheral wall being also fixed a hole and an inner chamber, and the hole communicating with the receiving groove; the inner chamber including a first sealing surface arranged on a predetermined position of an outer side thereof; the tubular member further including a first closing portion and a second closing portion secured on an outer surface of the peripheral rim, and including at least one cutout disposed between the first and the second closing portions and to communicate with the inner chamber; a watering member including a first cavity and a second cavity communicating with each other, a first water orifice and a second water orifice spaced apart from each other; the first water orifice being in communication with the first cavity and the second water orifice communicating with the second cavity, and a periphery of the first cavity engaged with the first and second closing portions of the tubular member, and a bottom wall of the first cavity keeping a certain distance away from the tubular member so that the first cavity communicates with the outlet, and the water orifice communicates with the inner chamber through the cutout, and a second sealing surface formed in the second cavity; a valve core formed in a post shape and inserting to the inner chamber and the hole of the tubular member axially, the valve core including a third closing portion attached on a central section thereof to retain the hole, and including a fourth closing portion arranged on an outer surface thereof, and a connecting portion disposed on an inner end thereof, such that the connecting portion is forced to actuate the valve core to move along the hole axially; as the fixing portion moves inward, the fourth closing portion abuts against the first sealing surface of the inner chamber so that the outlet of the tubular member communicating with the second water orifice via the first cavity and second cavity in order; as the fixing portion moves outward, the fourth closing portion abuts against the second sealing surface of the first cavity so that the outlet of the tubular member communicates with the second water orifice via the first cavity and second cavity in turn; an elastic element to push the valve core outward so that the fourth closing portion engages with the second sealing surface of the watering member; a housing including an internal room to receive the tubular member and the watering member; the internal room communicating with a side pore and a lower vacancy, the tubular member extending out of the side pore, the housing further including an installing space to couple with the tubular member and the watering member, and the installing space including a rotary shaft; a front cover installed in the vacancy of the housing and coupled to the watering member to be proximate to a first compartment and a second compartment to communicate with the first and the second water orifices respectively; a first watering element installed in the first compartment of the front cover, such that water flowing from the first water orifice forms a first mode of water flow; a second watering element installed in the second compartment of the front cover, such that the water flowing from the second water orifice forms a second mode of water flow; a control member including a coupling section disposed on a central portion thereof and an actuating portion formed on a front side thereof individually, and including a first press portion and a second press portion mounted on a top of a rear side and the front side thereof individually; the coupling section axially connected with the rotary shaft of the installing space of the housing to form a fulcrum to rotate the housing frontward and rearward; the actuating section passing through the installing space of the housing to connect with and actuate the connecting portion of the valve core.
