Referring to fig. 1 to 6, according to an embodiment of the first aspect of the present invention, a shower head for kitchen is provided, which includes a pressing valve 100, a piston cylinder 200, a first compression spring 300, and a shower head 400, the pressing valve 100 has a valve body 110 and a pressing rod 120, the valve body 110 has a water passing cavity 111 therein, two ends of the valve body 110 respectively have a water inlet 112 and a water outlet 113 communicated with the water passing cavity 111, a water stopping port 114 is disposed in the water passing cavity 111, the pressing rod 120 is inserted into the water stopping port 114, one end of the pressing rod 120 is provided with a pressing end 121 penetrating through the valve body 110, and the other end of the pressing rod 120 is provided with a water stopping piston 122 for closing the water stopping port 114; the piston cylinder 200 is arranged on the valve body 110, the water stopping piston 122 is inserted into the piston cylinder 200, a hydraulic cavity 210 is formed by one end of the water stopping piston 122, which is back to the water stopping port 114, and the piston cylinder 200, the water stopping piston 122 is provided with a water through hole 123 communicated with the hydraulic cavity 210, and the hydraulic cavity 210 is communicated with the water inlet 112 through the water through hole 123; the first compression spring 300 is positioned in the hydraulic cavity 210, one end of the first compression spring 300 abuts against the water stop piston 122, and the other end of the first compression spring 300 abuts against the piston cylinder 200; the shower head 400 is provided at the water outlet 113. The water inlet 112 and the water outlet 113 of the valve body 110 are located at two ends of the valve body 110, the middle part in the water passing cavity 111 is provided with a water stopping opening 114, and the water stopping piston 122 is located at one side of the water stopping opening 114 communicated with the water inlet 112. The valve body 110 is provided with a hole for the pressing end 121 to pass through, so that the pressing end 121 protrudes out of the valve body 110, so that a user can press the pressing rod 120 to open the water stopping hole 114, so that water flows from the water inlet 112 through the water stopping hole 114, flows out of the water outlet 113, and is finally sprayed out of the shower head 400 to clean kitchen utensils. A rubber sealing ring is arranged between the pressing end 121 and the hole wall of the valve body 110 to prevent water leakage. The rubber sealing rings are arranged on the inner wall of the piston cylinder 200 and the water stop piston 122, so that water in the hydraulic cavity 210 or water in the water inlet 112 is prevented from flowing through a gap between the piston cylinder 200 and the water stop piston 122, and water can only flow into or out of the hydraulic cavity 210 through the water through hole 123. The first compression spring 300 is used for driving the water stopping piston 122 to press the water stopping port 114, namely, for resetting, so that in the case that the pressing rod 120 is not pressed by a person, the first compression spring 300 will press the water stopping piston 122 to the water stopping port 114, and the effect of closing the water path is achieved.

When the pressing end 121 of the pressing rod 120 is pressed by a user, the water-stopping piston 122 of the pressing rod 120 will move in the direction of the piston cylinder 200, the water-stopping opening 114 is opened, the water inlet 112 and the water outlet 113 are communicated, and at this time, the water-stopping piston 122 lets the first compression spring 300 store energy and compress the space of the hydraulic pressure chamber 210, and the water pressure of the hydraulic pressure chamber 210 rises, so that the speed of the pressing rod 120 being pressed towards the piston cylinder 200 can be reduced, the rigid collision between the water-stopping piston 122 and the piston cylinder 200 is reduced, the damage to the water-stopping piston 122 and the piston cylinder 200 is reduced, secondly, when the water pressure in the hydraulic pressure chamber 210 rises, the water inlet 112 is communicated with the water-stopping opening 114, the water pressure at the water inlet 112 is low, the water in the hydraulic pressure chamber 210 will be squeezed out from the water through hole 123, flow towards the water inlet 112, the effect of reducing the water pressure in the hydraulic pressure chamber 210, preventing the piston cylinder 200 from exploding, and also reducing the force of pressing rod 120, the user can press the pressing rod 120 better, so that the shower head 400 can discharge water conveniently. The water through hole 123 serves to equalize the water pressure in the hydraulic pressure chamber 210 and the water pressure of the water inlet 112. The force required by the user to press the pressing rod 120 to open the water stopping port 114 is related to the size of the aperture of the water through hole 123, the larger the aperture of the water through hole 123 is, the larger the flow rate of the water through hole 123 is, the faster the pressure relief speed of the hydraulic cavity 210 is, the smaller the pressure applied by the water in the hydraulic cavity 210 to the water stopping piston 122 is, and therefore, the force required by the user to press the pressing rod 120 to open the water stopping port 114 is smaller. Conversely, the smaller the diameter of the water through hole 123, the greater the force required for the user to open the water stop port 114 by pressing the pressing rod 120. When the force applied to the pressing end 121 by the user is smaller than the elastic force of the first compression spring 300, the first compression spring 300 drives the water stopping piston 122 to close the water stopping port 114, at this time, the volume of the hydraulic cavity 210 will be increased, the water pressure in the hydraulic cavity 210 is reduced, and the water pressure in the hydraulic cavity 210 is smaller than the water pressure of the water inlet 112, so that the hydraulic cavity 210 generates suction to the water stopping piston 122, the moving speed of the water stopping piston 122 towards the water stopping port 114 is reduced, the impact force of the water stopping piston 122 colliding with the water stopping port 114 is reduced, the noise of the water stopping piston 122 colliding with the water stopping port 114 is reduced, the collision abrasion between the water stopping piston 122 and the water stopping port 114 is reduced, the service life of the pressing valve 100 is prolonged, the maintenance times. When the water pressure in the hydraulic chamber 210 is reduced, and the water pressure in the hydraulic chamber 210 is lower than the water pressure of the water inlet 112, the water in the water inlet 112 will flow into the hydraulic chamber 210 through the water through hole 123, so as to increase the water pressure in the hydraulic chamber 210, prevent the pressure in the hydraulic chamber 210 from being too low, and prevent the piston cylinder 200 from being damaged. The smaller the aperture of the water through hole 123 is, the smaller the pressure rising speed in the hydraulic cavity 210 is, the better the speed of the water stop piston 122 can be slowed down by the hydraulic cavity 210, the impact force between the water stop piston 122 and the water stop port 114 can be reduced better, and the water stop piston 122 and the water stop port 114 which are pressed against key parts in the valve 100 are prevented from being damaged. The water hole 123 is crossed in the cooperation of hydraulic pressure chamber 210, can slow down the speed that the pressing rod 120 was pressed down and was pushed back by first compression spring 300, lets the pressing rod 120 speed more even when removing to promote pressing of pressing valve 100 and feel, promote the feel of kitchen with the gondola water faucet.
