Abstract:
A kitchen showerhead and a kitchen faucet. The kitchen showerhead comprises a pressing valve (100), a piston cylinder (200), a first compression spring (300), and a showerhead body (400); the pressing valve (100) has a valve body (110) and a pressing rod (120); a water inlet (112) and a water outlet (113) are respectively formed on both ends of the valve body (110); a water stop opening (114) is formed in a water passing cavity (111); the pressing rod (120) is inserted into the water stop opening (114); a pressing end (121) and a water stop piston (122) are respectively provided on both ends of the pressing rod (120); the end of the water stop piston (122) facing away from the water stop opening (114) and the piston cylinder (200) form a hydraulic cavity (210); the water stop piston (122) is provided with a water passing hole (123) communicated with the hydraulic cavity (210); and the hydraulic cavity (210) is communicated with the water inlet (112) by means of the water passing hole (123). The combination of the hydraulic cavity and the water passing hole causes a movement speed of the pressing rod more uniform, thereby improving pressing handfeel, reducing an impact force between the water stop piston and the water stop opening, and reducing noise.
