[0002] The use of the faucet is mainly to use the valve stem of the ceramic valve core to provide operation through the handle, and the faucet can be opened or closed when the handle drives the valve stem to be pulled up. At the same time, some water-saving valve cores will automatically close after a certain amount of water flows out of the faucet.

[0003] However, the above patent has the following shortcomings:

[0004] The water flow rate of existing water-saving faucets is generally not adjustable, thereby reducing the application range of the device. Utility Model Content

[0005] The utility model provides a two-stage water-saving ceramic valve core structure, aiming to solve the problem that the water flow of the existing water-saving faucet mentioned in the above background technology is generally unable to be adjusted, thereby reducing the application range of the device.

[0006] The utility model is realized in this way: a two-stage water-saving ceramic valve core structure comprises a valve body, one side of the valve body is connected with a water inlet pipe, the other side of the valve body is connected with a water outlet pipe, a sealing ring is arranged between the water inlet pipe and the water outlet pipe, and a valve core structure for controlling the water output of the device is arranged inside the valve body;

[0007] The valve core structure includes an automatic reset component for automatically closing the valve body, and an adjusting component for adjusting the reset speed of the automatic reset component;

[0008] The automatic reset component comprises a sealing cylinder, which is arranged through the top of the valve body, a fixing ring is fixedly connected to the outer periphery of the bottom of the sealing cylinder, the outer periphery of the fixing ring is fixedly connected to the inner wall of the valve body, two through holes are formed on the side wall of the sealing cylinder, and a through groove is formed on the top of the sealing cylinder;

[0009] A push rod is provided through the middle of the sealing cylinder, a sealing plug is fixedly connected to the bottom of the push rod, the sealing plug corresponds to the sealing ring, a knob is rotatably connected to the top of the push rod, a piston is fixedly connected to the middle of the push rod, and the outer periphery of the piston is slidably connected to the sealing cylinder;

[0010] The piston surface is provided with a through groove, a slide rod is slidably provided in the middle of the through groove, a sealing plate is fixedly connected to the top of the slide rod, a limit plate is fixedly connected to the bottom of the slide rod, a plurality of guide grooves are opened on the periphery of the slide rod, a first return spring is provided on the top of the limit plate, the top of the first return spring abuts against the piston, the bottom of the first return spring abuts against the limit plate, and the number of the through grooves is set to be multiple;

[0011] A second return spring is provided at the bottom of the piston, the bottom of the second return spring abuts against the inner wall of the sealing cylinder, and the top of the second return spring abuts against the piston;

[0012] The regulating component comprises a slide groove, a limit groove and a guide ring, wherein the slide groove is provided at the top of the valve body and is arc-shaped;

[0013] The limiting groove is arranged on the outer periphery of the sealing cylinder;

[0014] A slider is slidably arranged on the outer side of the guide ring, a receiving groove is provided on the side wall of the slider, a ball is movably arranged inside the receiving groove, a pressing spring is arranged on one side of the ball, one end of the pressing spring abuts against the inner wall of the receiving groove, and the other end of the pressing spring abuts against the ball, and the through hole and the limiting groove are both matched with the ball;

[0015] A fixed sleeve rod is fixedly connected to the bottom of the knob, a fixed rod is slidably arranged at the bottom of the fixed sleeve rod, and the bottom of the fixed rod is fixedly connected to the sliding block.

[0016] By pressing the knob, the sealing plug can be driven downward by the push rod, so that the sealing plug and the sealing ring are separated from the seal, so that the water inlet pipe and the water outlet pipe are connected;

In this way, one of the two through holes can be sealed, thereby slowing down the speed at which outside air enters the sealing tube, and then slowing down the upward movement of the piston, so that after the device presses the knob, the sealing plug will seal the sealing ring later, thereby adjusting the water outlet time of the device, thereby improving the applicability of the device.

[0021] Preferably, a groove is provided on the outer periphery of the knob, the number of the grooves is set to be multiple, and the multiple grooves are distributed around the center of the knob;

[0022] The groove can be provided to prevent the user's hand from slipping off the knob.

[0052] Furthermore, a groove 3 is provided on the outer periphery of the knob 217 , and the number of the grooves 3 is set to be multiple, and the multiple grooves 3 are distributed around the center of the knob 217 .

[0053] The working principle and use process of this utility model:

[0054] By pressing the knob 217, the sealing plug 216 can be driven downward through the push rod 215, so that the sealing plug 216 and the sealing ring 13 are separated from the seal, so that the water inlet pipe 11 and the water outlet pipe 12 are connected;

[0055] When the push rod 215 moves downward, the piston 218 will be driven to move downward in the sealing cylinder 211. At this time, part of the gas at the bottom of the piston 218 will be discharged through the through hole 213 on the side wall of the sealing cylinder 211, and the other part will be discharged from the top of the piston 218 through the guide groove 2113 to push open the sealing plate 2111, and the first return spring 2114 and the second return spring 2115 will be compressed.

[0056] After the knob 217 is released, the first return spring 2114 will be reset and drive the sealing plate 2111 to seal the through groove 219 through the limit plate 2112 and the slide rod 2110, and the second return spring 2115 will drive the piston 218 to move upward. When the piston 218 moves upward, the inside of the sealing cylinder 211 is in a negative pressure state. Since the diameter of the through hole 213 is small, the outside air will slowly enter the space at the bottom of the piston 218, thereby causing the piston 218 to move upward slowly, and then causing the push rod 215 and the sealing plug 216 to move upward slowly until the top of the sealing plug 216 abuts against the sealing ring 13, thereby sealing the inside of the valve body 1;

[0057] The above structure allows the water inlet pipe 11 to be connected to the water outlet pipe 12 when the knob 217 is pressed, and the water inlet pipe 11 and the water outlet pipe 12 are automatically sealed after a period of time after the knob 217 is released, so that the device can discharge water quantitatively, thereby avoiding the waste of water resources;

[0058] By rotating the knob 217, the slider 224 can be driven to slide on the surface of the guide ring 223 through the fixed rod 229 at the bottom of the fixed sleeve rod 228, so that the ball 226 at the end of the slider 224 slides from the position of the limit groove 222 to the position of the through hole 213 and seals the through hole 213. In this way, one of the two through holes 213 can be sealed, so that the speed at which the outside air enters the sealing tube 211 is slowed down, and then the speed at which the piston 218 moves upward is slowed down, so that after the device presses the knob 217, the sealing plug 216 will seal the sealing ring 13 later, thereby adjusting the water outlet time of the device, thereby improving the application range of the device.
