Electronic pull-out faucet

Abstract

An electronic pull-out faucet including a faucet body, a pull-out hose, a water outlet, a control box, a travel switch and a mechanical pressing mechanism. The pull-out hose movably penetrates through the pull-out channel. Two ends of the pull-out hose connect to the water outlet and the control box respectively. The travel switch controls whether the control box discharges water or not. The mechanical pressing mechanism movably presses the travel switch with the movement of the pull-out hose. The electronic pull-out faucet can automatically discharge water when the pull-out hose is pulled out, which is convenient to use.

What is claimed is: 
     
         1 . An electronic pull-out faucet, comprising a faucet body, a pull-out hose, a water outlet, a control box, a travel switch and a mechanical pressing mechanism;
 the faucet body is provided with a pull-out channel; the pull-out hose movably penetrates through the pull-out channel; the water outlet is connected with a water outlet end of the pull-out hose; a water outlet end of the control box is connected with a water inlet end of the pull-out hose; the travel switch is fixedly arranged in the pull-out channel; the travel switch is electrically connected with the control box and controls whether the control box discharges water or not;   the mechanical pressing mechanism comprises a movable part, a switching part and a resetting part arranged in the pull-out channel; the switching part movably sleeves the pull-out hose and movably presses a button of the travel switch; the movable part is fixedly fitted with the pull-out hose and movably presses the switching part; the resetting part cooperates with the switching part and is configured to drive the switching part to release pressing of the button of the travel switch;   when the pull-out hose is in a reset state, the movable part presses the switching part to enable the switching part to press the button of the travel switch, so that the travel switch controls the control box to stop water discharge;   when the pull-out hose is in a pull-out state, the movable part is released from pressing the switching part, and the switching part is released from pressing the button of the travel switch under action of the resetting part, so that the travel switch controls the control box to discharge water.   
     
     
         2 . The electronic pull-out faucet as in  claim 1 , wherein the resetting part is a spring structure with a first end thereof abutting against the switching part and a second end thereof abutting against a fixing seat arranged inside the faucet body; the fixing seat is disposed on one side of the switching part distant from the movable part. 
     
     
         3 . The electronic pull-out faucet as in  claim 1 , wherein the switching part is provided with at least one movable magnet; the resetting part comprises at least one fixed magnet which is fixedly provided in the faucet body; each of the at least one movable magnet magnetically repels each of the at least one fixed magnet. 
     
     
         4 . The electronic pull-out faucet as in  claim 1 , wherein the travel switch is obliquely arranged relative to the pull-out hose; one end of the switching part close to the travel switch forms a pressing part configured to movably press the button of the travel switch. 
     
     
         5 . The electronic pull-out faucet as in  claim 4 , wherein the pressing part of the switching part has a pressing inclined surface that tapers toward the pull-out hose along a direction from the switching part to the travel switch; the pressing inclined surface movably presses the button of the travel switch. 
     
     
         6 . The electronic pull-out faucet as in  claim 4 , wherein the pressing part is cylindrical, and the pressing part movably sleeves the pull-out hose. 
     
     
         7 . The electronic pull-out faucet as in  claim 1 , wherein the faucet body comprises a faucet bent pipe and a faucet main body which are rotatably connected to each other; the travel switch is arranged in the faucet main body. 
     
     
         8 . The electronic pull-out faucet as in  claim 4 , wherein the control box comprises a box body, and a control circuit board and a solenoid valve arranged inside the box body; the solenoid valve has a water outlet end that serves as the water outlet end of the control box; the control circuit board is electrically connected to both the travel switch and the solenoid valve. 
     
     
         9 . The electronic pull-out faucet as in  claim 8 , wherein an infrared sensor is installed on the faucet body; the infrared sensor is electrically connected with the control circuit board. 
     
     
         10 . The electronic pull-out faucet as in  claim 1 , wherein the pull-out hose is provided with a counter weight.
