With reference to <FIG>, according to an embodiment in a first aspect of the disclosure, a kitchen showerhead is provided, which comprises a pressing valve <NUM>, a piston cylinder <NUM>, a first compression spring <NUM> and a showerhead body <NUM>. The pressing valve <NUM> is provided with a valve body <NUM> and a pressing rod <NUM>, a water passing cavity <NUM> is arranged in the valve body <NUM>, a water inlet <NUM> and a water outlet <NUM> which are communicated with the water passing cavity <NUM> are respectively arranged on both ends of the valve body <NUM>, a water stop opening <NUM> is arranged in the water passing cavity <NUM>, the pressing rod <NUM> is inserted into the water stop opening <NUM>, one end of the pressing rod <NUM> is provided with a pressing end <NUM> penetrating through the valve body <NUM>, and the other end of the pressing rod <NUM> is provided with a water stop piston <NUM> for closing the water stop opening <NUM>. The piston cylinder <NUM> is arranged on the valve body <NUM>, the water stop piston <NUM> is inserted into the piston cylinder <NUM>, one end of the water stop piston <NUM> facing away from the water stop opening <NUM> and the piston cylinder <NUM> form a hydraulic cavity <NUM>, the water stop piston <NUM> is provided with a water passing hole <NUM> communicated with the hydraulic cavity <NUM>, and the hydraulic cavity <NUM> is communicated with the water inlet <NUM> through the water passing hole <NUM>. The first compression spring <NUM> is located in the hydraulic cavity <NUM>, one end of the first compression spring <NUM> abuts against the water stop piston <NUM>, and the other end of the first compression spring <NUM> abuts against the piston cylinder <NUM>. The showerhead body <NUM> is arranged at the water outlet <NUM>. The water inlet <NUM> and the water outlet <NUM> of the valve body <NUM> are located on both ends of the valve body <NUM>, a middle portion in the water passing cavity <NUM> is provided with the water stop opening <NUM>, and the water stop piston <NUM> is located on one side of the water stop opening <NUM> communicated with the water inlet <NUM>. The valve body <NUM> is provided with a hole for the pressing end <NUM> to penetrate through, which facilitates the pressing end <NUM> to protrude from the valve body <NUM>, and is convenient for a user to press the pressing rod <NUM> to open the water stop opening <NUM>, so that water flows through the water stop opening <NUM> from the water inlet <NUM>, flows out from the water outlet <NUM>, and finally is sprayed out from the showerhead body <NUM> to clean kitchen utensils. A rubber sealing ring is arranged between the pressing end <NUM> and a hole wall of the valve body <NUM> to prevent water leakage. There is also a rubber sealing ring arranged between an inner wall of the piston cylinder <NUM> and the water stop piston <NUM> to prevent water in the hydraulic cavity <NUM> or water in the water inlet <NUM> from flowing through a gap between the piston cylinder <NUM> and the water stop piston <NUM>, so that water can only flow into or out of the hydraulic cavity <NUM> through the water passing hole <NUM>. The first compression spring <NUM> is configured for driving the water stop piston <NUM> to press to the water stop opening <NUM>, which means that the first compression spring is configured for reset, so that the first compression spring <NUM> will press the water stop piston <NUM> to the water stop opening <NUM> when no one presses the pressing rod <NUM>, thereby achieving a function of closing a waterway.

When the pressing end <NUM> of the pressing rod <NUM> is pressed by the user, the water stop piston <NUM> of the pressing rod <NUM> will move towards the piston cylinder <NUM> to open the water stop opening <NUM> and communicate the water inlet <NUM> with the water outlet <NUM>. Moreover, the water stop piston <NUM> allows the first compression spring <NUM> to store energy and compress a space of the hydraulic cavity <NUM> at the moment, so that a water pressure in the hydraulic cavity <NUM> is increased, thereby reducing a speed at which the pressing rod <NUM> is pressed to the piston cylinder <NUM>, reducing rigid collisions between the water stop piston <NUM> and the piston cylinder <NUM>, and reducing damages of the water stop piston <NUM> and the piston cylinder <NUM>. Secondly, when the water pressure in the hydraulic cavity <NUM> is increased, the water inlet <NUM> is communicated with the water stop opening <NUM>, then a water pressure at the water inlet <NUM> is low, and water in the hydraulic cavity <NUM> will be squeezed out of the water passing hole <NUM> and flow to the water inlet <NUM>, which serves to reduce the water pressure in the hydraulic cavity <NUM>, thereby preventing the piston cylinder <NUM> from exploding, reducing a force pressed to the pressing rod <NUM>, allowing the user to better press the pressing rod <NUM>, and facilitating the showerhead body <NUM> to discharge water. The water passing hole <NUM> is configured for balancing the water pressure in the hydraulic cavity <NUM> and the water pressure at the water inlet <NUM>. A force required for the user to press the pressing rod <NUM> to open the water stop opening <NUM> is related to the size of the water passing hole <NUM>. The larger the size of the water passing hole <NUM> is, the larger the flow rate of the water passing hole <NUM> will be, then the faster the pressure relief speed of the hydraulic cavity <NUM> will be, and then the smaller the pressure exerted by the water in the hydraulic cavity <NUM> on the water stop piston <NUM> will be. Therefore, the force required for the user to press the pressing rod <NUM> to open the water stop opening <NUM> will be smaller. On the contrary, the smaller the size of the water passing hole <NUM> is, the larger the force required for the user to press the pressing rod <NUM> to open the water stop opening <NUM> will be. When a force exerted by the user on the pressing end <NUM> is smaller than an elastic force of the first compression spring <NUM>, the first compression spring <NUM> will drive the water stop piston <NUM> to close the water stop opening <NUM>, which will increase a volume of the hydraulic cavity <NUM> and reduce the water pressure in the hydraulic cavity <NUM>, and then the water pressure in the hydraulic cavity <NUM> is lower than the water pressure at the water inlet <NUM>, so that the hydraulic cavity <NUM> generates a suction force for the water stop piston <NUM>, thereby reducing a moving speed of the water stop piston <NUM> to the water stop opening <NUM>, reducing an impact force generated by the water stop piston <NUM> colliding with the water stop opening <NUM>, reducing noise generated by the water stop piston <NUM> colliding with the water stop opening <NUM>, and reducing collision abrasions of the water stop piston <NUM> and the water stop opening <NUM>, so as to prolong a service life of the pressing valve <NUM>, reduce maintenance times of the pressing valve <NUM>, and reduce maintenance costs. When the water pressure in the hydraulic cavity <NUM> is reduced, and then the water pressure in the hydraulic cavity <NUM> is lower than the water pressure at the water inlet <NUM>, water in the water inlet <NUM> will flow into the hydraulic cavity <NUM> from the water passing hole <NUM>, thereby increasing the water pressure in the hydraulic cavity <NUM>, preventing a pressure in the hydraulic cavity <NUM> from being too low, and preventing the piston cylinder <NUM> from being damaged. The smaller the size of the water passing hole <NUM> is, the lower the recovering speed of the pressure in the hydraulic cavity <NUM> will be, so that the hydraulic cavity <NUM> can better reduce a speed of the water stop piston <NUM>, can better reduce the impact force between the water stop piston <NUM> and the water stop opening <NUM>, preventing the water stop piston <NUM> and the water stop opening <NUM> at key positions in the pressing valve <NUM> from being damaged. The hydraulic cavity <NUM> is cooperated with the water passing hole <NUM>, which can reduce a speed at which the pressing rod <NUM> is pressed and a speed at which the pressing rod is pushed back by the first compression spring <NUM>, and make a moving speed of the pressing rod <NUM> more uniform, thereby improving pressing hand feeling of the pressing valve <NUM> and hand feeling of the kitchen showerhead.

With reference to <FIG>, according to some embodiments in the first aspect of the disclosure, in order to better enable the user to press the pressing end <NUM>, the valve body <NUM> of the pressing valve <NUM> is hinged with a switch handle <NUM>, and a middle portion of the switch handle <NUM> abuts against the pressing end <NUM>, which means that the user may press the pressing end <NUM> by pressing the switch handle <NUM>, so that it is effort-saving and convenient for the user to control opening and closing of the pressing valve <NUM>. On the above basis, the valve body <NUM> is hinged with a constantly-opened pressing ring <NUM>, and the switch handle <NUM> is provided with a clamping groove matched with the constantly-opened pressing ring <NUM>. When the constantly-opened pressing ring <NUM> is clamped in the clamping groove, the constantly-opened pressing ring <NUM> may make the switch handle <NUM> press the pressing end <NUM> to open the pressing valve <NUM>, so that when kitchen utensils are washed, the constantly-opened pressing ring <NUM> is cooperated with the clamping groove. Therefore, the pressing valve <NUM> can be opened without pressing the switch handle <NUM> for a long time, which facilitates washing the kitchen utensils and is convenient for use.

With reference to <FIG>, according to some embodiments in the first aspect of the disclosure, the water inlet <NUM> of the valve body <NUM> is connected with a handle <NUM>, and a middle portion of the handle <NUM> is provided with a water conveying pipe <NUM> communicated with the water inlet <NUM>, which means that tap water may be input from the water conveying pipe <NUM> and flow into the water inlet <NUM>, thereby ensuring water supply of the kitchen showerhead. Moreover, the handle <NUM> may be grasped by the user, which is convenient for the user to press the pressing end <NUM> with a hand. Moreover, cooperated with the switch handle <NUM> above, it is more convenient for the user to press the pressing end <NUM>, so that it is convenient for the user to use.

With reference to <FIG> and <FIG>, according to some embodiments in the first aspect of the disclosure, one side of the water stop piston <NUM> facing the water stop opening <NUM> is provided with a sealing plug <NUM> for closing the water stop opening <NUM>. The sealing plug <NUM> may make the water stop piston <NUM> close the water stop opening <NUM>, and the sealing plug <NUM> can further reduce an impact force of the water stop piston <NUM> on the water stop opening <NUM>, thereby further reducing impact noise between the water stop piston <NUM> and the water stop opening <NUM>, better protecting the water stop piston <NUM> and the water stop opening <NUM>, and reducing abrasions of the water stop piston <NUM> and the water stop opening <NUM>. Specifically, one side of the water stop piston <NUM> facing the water stop opening <NUM> is provided with a mounting groove, and the sealing plug <NUM> is mounted in the mounting groove. It should be noted that the sealing plug <NUM> is a rubber plug. In addition, the sealing plug <NUM> may also be a plug for sealing, such as a wooden plug.

With reference to <FIG> and <FIG>, according to some embodiments in the first aspect of the disclosure, a middle portion of the pressing rod <NUM> is provided with a conical section <NUM>, a larger end of the conical section <NUM> is connected with the water stop piston <NUM>, and a smaller end of the conical section <NUM> is connected with the pressing end <NUM>. The conical section <NUM> penetrates through the water stop opening <NUM>, which means that the conical section <NUM> is located in the water stop opening <NUM>. When the pressing rod <NUM> pushes the water stop piston <NUM> to move towards the piston cylinder <NUM>, the water inlet <NUM> is communicated with the water outlet <NUM> through a gap between the conical section <NUM> and the water stop opening114. Since the larger end of the conical section <NUM> is connected with the water stop piston <NUM>, when the pressing rod <NUM> pushes the water stop piston <NUM> to move towards the piston cylinder <NUM>, the gap between the conical section <NUM> and the water stop opening <NUM> will be gradually increased, so that a flow rate of the water outlet <NUM> can be increased, thereby achieving the purpose of adjusting a flow rate of the showerhead body <NUM>. On the above basis, an outer diameter of the larger end of the conical section <NUM> is matched with an inner diameter of the water stop opening <NUM>. That is, the outer diameter of the larger end of the conical section <NUM> is equal to the inner diameter of the water stop opening <NUM>, so that the larger end of the conical section <NUM> can also close the water stop opening <NUM>, and then the water stop opening <NUM> can be better closed through the cooperation between the conical section <NUM> and the water stop piston <NUM>, thereby preventing water leakage.

With reference to <FIG> and <FIG>, according to some embodiments in the first aspect of the disclosure, the water stop piston <NUM> is provided with an accommodating groove <NUM> for accommodating the first compression spring <NUM>, and the water passing hole <NUM> is located in a groove wall of the accommodating groove <NUM>. That is, one side of the water stop piston <NUM> facing the piston cylinder <NUM> is provided with the accommodating groove <NUM>, so that the first compression spring <NUM> can be placed in the accommodating groove <NUM>, thereby preventing the first compression spring <NUM> from being separated from the water stop piston <NUM>. Therefore, the first compression spring <NUM> can better make the water stop piston <NUM> reset. Moreover, the water passing hole <NUM> is located in the groove wall of the accommodating groove <NUM>, which is convenient for forming the water passing hole <NUM> in the water stop piston <NUM>.

According to some embodiments in the first aspect of the disclosure, when the pressing rod <NUM> is pressed to an end, a cylinder wall of the piston cylinder <NUM> closes the water passing hole <NUM>, which means that after the user presses the pressing rod <NUM>, the piston cylinder <NUM> may close the water passing hole <NUM>. At the moment, the hydraulic cylinder <NUM> is closed, and the water pressure in the hydraulic cylinder <NUM> cannot be released, so that a maximum resistance force of the pressing rod <NUM> is exerted on the hand of the user to realize feedback to the hand of the user, thereby improving pressing hand feeling of the pressing valve <NUM>.

With reference to <FIG>, <FIG>, <FIG>, according to some embodiments in the first aspect of the disclosure, the showerhead body <NUM> comprises a first valve seat <NUM>, a second valve seat <NUM> rotatably connected with the first valve seat <NUM>, and a showerhead nozzle <NUM> and a fan-shaped nozzle <NUM> which are arranged on the second valve seat <NUM>.

When the second valve seat <NUM> rotates around the first valve seat <NUM>, movement trajectories of the second input hole <NUM> and the third input hole <NUM> will pass through the first output hole <NUM>, so that the first output hole <NUM> may be communicated with one of the second input hole <NUM> and the third input hole <NUM>. When the first output hole <NUM> is communicated with the second input hole <NUM>, water discharged from the water outlet <NUM> will flow through the first input hole <NUM>, the first output hole <NUM> and the second input hole <NUM>, and then the water is sprayed out from the showerhead nozzle <NUM>, thereby achieving the purpose of making the showerhead nozzle <NUM> spray water to clean the kitchen utensils. Similarly, when the first output hole <NUM> is communicated with the third input hole <NUM>, the water discharged from the water outlet <NUM> will flow through the first input hole <NUM>, the first output hole <NUM> and the third input hole <NUM>, and then V-shaped water mist will be sprayed out from the fan-shaped nozzle <NUM> to clean the kitchen utensils. That is, the second valve seat <NUM> may rotate by <NUM> degrees, and the first output hole <NUM> may be selected to be communicated with the second input hole <NUM> or the third input hole <NUM> during rotation, thereby achieving the purpose of selecting a water discharge type.
