<p>A switching unit for pushbutton of kitchen water faucet cooperates with a water faucet body (1), a mandrel (2), a pushbutton mechanism (3), a bubbler (5) and a face covering (6). Two intake pipes (21, 22) formed vertically in the middle of the mandrel (2) are communicated with the water inlet of the bubbler (5) and the shower water inlet of the face covering (6) respectively. The pushbutton mechanism (3) is arranged in the sidewall of water faucet body (1) and includes two buttons (32, 33) capable of returning to initial state which aim at said two intake pipes (21, 22). The valve core assembly (4) includes two valves (41, 42), a pressure plate (43), and a return spring (44). Said two valves (41, 42) extend into said two intake pipes (21, 22) of said mandrel (2) respectively, and the return spring (44) is arranged below the valve (41) in the bubble water intake pipe (21). The middle of the pressure plate (43) is connected pivotally with the upside of the partition between said two intake pipes (21, 22), and the two ends of the pressure plate (43) are connected pivotally with the upside of said two valves (41, 42) respectively. The pushbutton mechanism (3) and the valve core assembly (4) are arranged dividually and realize the switchover of shower water and bubble water using theseesaw principle. The return spring (44) makes said water faucet always keeping the bubble water state before water is turned on.</p> |
