Technical Field
[0001] The utility model relates to the field of faucets, in particular to an adjustable segmented water-saving faucet. Background Art
[0002] A faucet is a switch for controlling the water flow. Generally, a faucet has a faucet body, a faucet neck, and a faucet spout provided on the lower surface of the end of the faucet neck. When the faucet is opened, the water flow in the water inlet pipeline will sequentially pass through the faucet body and the faucet neck and flow into the faucet spout, and finally flow out from the faucet spout for use. The faucet valve core for controlling the opening and closing of the faucet is located at the position where the faucet neck and the faucet body communicate with each other. Therefore, when the valve core is closed, the water flow remaining in the faucet neck will still flow out from the faucet spout, resulting in waste of this part of the water flow. A water-saving faucet is a type of faucet that can intercept the water flow in the faucet neck within the faucet neck while the valve core is closed, achieving a water-saving effect.
[0003] The water-saving faucet realizes the automatic opening and closing of the faucet spout by arranging a water-saving structure inside the faucet spout. The water-saving structure mainly consists of an opening and closing plate and a spring. The opening and closing plate can use the elasticity of the spring to block and seal the faucet spout when the faucet does not discharge water. When the faucet discharges water, the water pressure is greater than the elasticity of the spring, so as to push the opening and closing plate to open the faucet spout. As the faucet is closed, after losing the action of the water pressure, the spring will reset the opening and closing plate through its own elasticity to block and seal the faucet spout again, achieving the water-saving effect. In the actual use process of the water-saving faucet, in order to ensure that the water pressure can be greater than the elasticity of the spring and realize the normal water discharge of the water-saving faucet, the valve core will be fully opened. However, during the use of the water flow, due to different usage situations, the requirements for the water flow rate are also different. However, it is difficult for a traditional faucet to finely control the water discharge flow rate by rotating the valve core with a handle. If the water discharge flow rate is too small, it is difficult to overcome the elasticity of the spring to open the faucet spout. If the water discharge flow rate is too large, it will cause waste of water resources, and large-flow water discharge is extremely likely to generate water discharge noise. Summary of the Invention
[0004] The technical problem to be solved by the utility model is to provide an adjustable segmented water-saving faucet, which can not only effectively adjust the water flow rate to meet the actual needs, but also effectively reduce the water discharge noise.

[0020] In the center of the inner wall on the upper side of the adjustment cover 13, there is a connection hole 16; in the center of the outer wall on the upper side of the adjustment cover 13, there is a groove 17; in the center of the bottom of the groove 17, there is a through hole 18 that communicates with the connection hole 16; the upper end of the screw rod 12 penetrates into the connection hole 16 and presses against the bottom of the connection hole 16; on the left and right sides of the outer wall of the upper end of the screw rod 12, there are symmetrically arranged card slots 19; on the left and right sides of the inner wall of the connection hole 16, there are clamping blocks 20 that match the card slots 19; in the center of the upper end surface of the screw rod 12, there is a threaded hole 21; a screw 22 passes downwards through the through hole and is screwed into the threaded hole 21, and the head of the screw 22 fits against the bottom of the groove 17.
[0021] The lower-section water-saving structure further includes a diversion seat 23 located in the water outlet hole 7; in the center of the upper surface of the diversion seat 23, there is a buffer hole 24; the lower end of the closing pipe 9 penetrates downwards into the buffer hole 24; in the buffer hole 24, there is an elastic structure; in the lower part of the buffer hole 24, there is a closing plate 25 located between the elastic structure and the lower end surface of the closing pipe 9, and the closing plate 25 shields and seals the lower end opening of the closing pipe; on the outer wall of the middle part of the closing pipe 9, there is a connection part 26 screwed into the upper end opening of the buffer hole 24; on the connection part 26, there are several water passing holes 27 evenly distributed in a circle.
[0022] The elastic structure includes a number of guide seats 28 evenly arranged in a circle at the bottom of the buffer hole 24; a guide hole 29 is provided at the center of the upper end surface of the guide seat 28; a number of guide rods 30 matching the guide hole 29 are provided on the lower surface of the opening and closing plate 25; there is a lower moving distance 31 between the lower end surface of the guide rod 30 and the bottom of the guide hole 29; there is an upper moving distance 32 between the upper end surface of the guide seat 28 and the lower surface of the opening and closing plate 25; a spring 33 sleeved outside the guide seat 28 is provided between the lower surface of the opening and closing plate 25 and the bottom of the buffer hole 24.
[0023] An annular sealing groove 34 is provided at the position on the upper surface of the opening and closing plate 25 opposite to the lower end surface of the opening and closing pipe 9; a sealing ring 35 matching the sealing groove 34 is provided in the sealing groove 34.
[0024] A number of anti-slip protrusions 36 evenly distributed in a circle are provided on the outer wall of the adjusting cover 13.
[0025] The usage method of the present utility model is as follows:
[0026] Since an adjusting conical surface 15 with an upper width and a lower narrow is provided on the outer wall of the lower part of the adjusting head 14, the gap between the outer wall of the lower part of the adjusting head 14 and the inner wall of the upper part of the opening and closing pipe 9 will gradually decrease from bottom to top. Therefore, when the user rotates the screw rod 12 through the adjusting cover 13 to move the adjusting head 14 upward, the actual water inlet area of the upper end opening of the opening and closing pipe 9 will gradually increase, effectively controlling the flow rate of water flowing into the opening and closing pipe 9, thereby effectively controlling the final water outlet flow rate of the faucet nozzle 5. The screw rod 12 is screwed into the screw connection hole 21, and the threaded fixing method between the two can accurately control the stroke of the adjusting head 14 moving up and down, thereby accurately controlling the water inlet flow rate of the upper end opening of the opening and closing pipe 9, and can automatically fix the position of the adjusting head 14 when the adjusting cover 13 stops rotating.
[0027] When a water-saving faucet needs to be used, the valve core in the faucet body 1 can be opened through the handle 3. At this time, the water flow in the water inlet pipeline connected to the faucet body 1 will enter the faucet neck 4 through the faucet body 1. If the adjusting head 14 does not block and seal the upper end opening of the opening and closing pipe 9 at this time, the water flow will enter the opening and closing pipe 9 through the upper end opening of the opening and closing pipe 9. At this time, the water flow entering the opening and closing pipe 9 will push the opening and closing plate 25 downward. When the opening and closing plate 25 moves downward, the guide rod 30 moves downward synchronously, and the spring 33 is compressed and generates elasticity. At this time, the lower end opening of the opening and closing pipe 9 is no longer shielded and sealed by the opening and closing plate 25, and the water flow in the opening and closing pipe 9 will enter the gap between the outer wall of the opening and closing pipe 9 and the inner wall of the buffer hole 24 through the gap between the lower end surface of the opening and closing pipe 9 and the upper surface of the opening and closing plate 25, and then enter the gap between the upper surface of the flow guiding seat 23 and the inner wall of the upper side of the water outlet hole 7 through the water passing hole 27, and finally flow out of the faucet nozzle 5 through the gap between the outer wall of the flow guiding seat 23 and the inner wall of the water outlet hole 7 and the lower end orifice of the water outlet hole 7 in sequence to realize the water outlet of the faucet.
[0028] When the faucet is not in use, the valve core can be closed through the handle 3. At this time, with the subsequent water flow lost, the water pressure in the opening and closing pipe 9 will drop suddenly, and the spring 33 will use its own elasticity to move the opening and closing plate 25 upward to reset. At this time, the opening and closing plate 25 will cover and seal the lower end opening of the opening and closing pipe 9 again, so as to intercept the water flow in the faucet neck 4 and avoid the situation that the water flow remaining in the faucet neck 4 still flows out of the faucet spout 5 when the user does not use it, resulting in waste.
[0029] Before the water flow flows out of the faucet spout 5, it will surely press down the opening and closing plate 25, causing the spring 33 to generate elasticity. This elasticity will act on the outward flowing water flow through the opening and closing plate 25, effectively buffering the water pressure and avoiding the situation of excessive noise caused by too large water pressure. Moreover, the cooperation among the opening and closing pipe 9, the diversion seat 23 and the faucet spout 5 makes the water flow not flow out to the outside in a straight line manner after flowing out of the faucet neck 4, but makes the flow trajectory tortuous, thus avoiding the situation that the water flow is easy to generate noise in a straight line flow manner and effectively achieving the noise reduction effect.
[0030] In summary, the present utility model can completely open the faucet through the handle 3, and then adjust the water flow rate by rotating the adjustment cover 13 in the upper section adjustment structure. While accurately controlling the water flow rate, it ensures the normal operation of the water-saving function. At the same time, the spring 33 in the lower section water-saving structure can not only cooperate with the opening and closing plate 25 to achieve the water-saving effect, but also effectively buffer the water pressure of the water flow, and can further change the water flow trajectory through the assembly relationship among the opening and closing pipe 9, the diversion seat 23 and the faucet spout 5, avoiding the situation of large noise caused by direct flow, and achieving the noise reduction effect to the greatest extent.
[0031] A connection hole 16 is provided at the center of the inner wall on the upper side of the adjustment cover 13. A groove 17 is provided at the center of the outer wall on the upper side of the adjustment cover 13. A through hole 18 communicating with the connection hole 16 is provided at the center of the bottom of the groove 17. The upper end of the screw rod 12 penetrates into the connection hole 16 and abuts against the bottom of the connection hole 16. Symmetrically arranged clamping grooves 19 are provided on the left and right sides of the outer wall of the upper end of the screw rod 12. Clamping blocks 20 matching with the clamping grooves 19 are provided on the left and right sides of the inner wall of the connection hole 16. A threaded hole 21 is provided at the center of the upper end surface of the screw rod 12. A screw 22 passes downward through the through hole 18 and is screwed into the threaded hole 21. The head of the screw 22 fits against the bottom of the groove 17. This fixing method can not only ensure the stability when the screw rod 12 is connected and fixed to the adjustment cover 13, but also facilitate the disassembly and assembly of the adjustment cover 13.
[0032] An annular sealing groove 34 is provided at a position on the upper surface of the opening and closing plate 25 opposite to the lower end surface of the opening and closing pipe 9. A sealing ring 35 matching the sealing groove 34 is provided in the sealing groove 34. The presence of the sealing ring 35 can effectively improve the sealing performance between the lower end surface of the opening and closing pipe 9 and the upper surface of the opening and closing plate 25, thereby effectively avoiding water leakage when the lower end opening of the opening and closing pipe 9 is shielded and sealed by the opening and closing plate 25.
[0033] A number of anti-slip protrusions 36 are evenly distributed in a circumferential manner on the outer wall of the adjusting cover 13. The presence of the anti-slip protrusions 36 can effectively increase the friction force between the hand and the outer wall of the adjusting cover 13, thereby facilitating the rotation of the adjusting cover 13.
