Embodiment
Shown in Fig. 1-5; A kind of construction of switch comprises water chamber 10, and water chamber 10 is provided with refluxing opening 11 and delivery port 12; Wherein, Also be provided with switch module on the water chamber 10, switch module comprises switch key 21, sensitive switch 22 and is used to seal the valve member of refluxing opening 11 that sensitive switch 22 is connected with power supply; Switch key 21 drives sensitive switch 22 and valve member, controls the break-make of power supply and the switching of refluxing opening 11 simultaneously.When energising, refluxing opening 11 is closed, and hot water flows out from delivery port 12; When outage, refluxing opening 11 is opened, and hot water is back to the water-supply structure from refluxing opening 11.
Further, described valve member is a valve rod 24.Up and down through valve rod 24 can effectively seal or open refluxing opening 11, and control be convenient.
Switch module also comprises the self-lock switch 23 that is used to locate valve rod 24 positions, the resetting structure that is used for reset switch button 21; Resetting structure is located between water chamber 10 and the switch key 21, and water chamber 10 is provided with the location structure 13 that is used to limit valve rod 24 portion's motion within it.When switch key 21 was pressed, valve rod 24 moved to certain stroke, and self-lock switch 23 can lock valve rod 24 positions, and 24 pairs of refluxing openings 11 of valve rod seal, and sensitive switch 22 is connected simultaneously; When Push switch button 21 once more; Self-lock switch 23 releases, the shell fragment on resetting structure or the sensitive switch 22 is upspring switch key 21, also can be that the shell fragment on resetting structure and the sensitive switch is upspring switch key simultaneously; Switch key 21 drives valve rod 24 and moves upward; Valve rod leaves refluxing opening 11, and refluxing opening 11 is opened, and sensitive switch 22 power supplys break off simultaneously.
