[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: a high-flow faucet with a detachable and washable filter screen, including a three-way faucet 1, a water outlet seat 2 at the bottom of the three-way faucet 1, a threaded structure at the bottom of the water outlet seat 2, a hexagonal inner groove structure at the top of the inner side of the water outlet seat 2, a flow mechanism 3 at the inner side of the three-way faucet 1, the flow mechanism 3 being used to lift and rotate to control the water flow, and a filter mechanism 4 at the top of the water outlet seat 2, the filter mechanism 4 being used to filter impurities in the water;

[0034] The flow mechanism 3 includes a lifting rod 31, the outer side of which is located inside the three-way faucet 1. A valve core 32 is fixedly connected to the bottom of the lifting rod 31, and a rubber ring 33 is fixedly connected to the outer side of the lifting rod 31. A sealing ring 34 is fixedly connected to the bottom of the valve core 32. An adjusting component 35 is provided on the outer side of the valve core 32. The adjusting component 35 includes an adjusting threaded ring 351, the inner side of which is fixedly connected to the inner side of the water outlet seat 2. An adjusting mechanism is provided at the top of the inner side of the three-way faucet 1. The top of the lifting rod 31 is provided with a plug-in assembly 36, which includes a mounting post 361. The bottom of the mounting post 361 is fixedly connected to the top of the lifting rod 31. The outer wall of the mounting post 361 is provided with multiple fastening threads 362. The top of the plug-in assembly 36 is provided with a screwing assembly 37, which includes a retaining ring 371. The inner side of the retaining ring 371 is provided on the outer side of the mounting post 361. A handwheel 372 is fixedly connected to the outer side of the retaining ring 371.

[0035] Specifically, the flow mechanism 3 controls the water flow rate. The handwheel 372 of the lifting and rotating component 37 is pulled and rotated. The handwheel 372 drives the fixed ring 371 to move synchronously. The fixed ring 371 drives the mounting post 361 of the insertion and removal component 36 to move. The mounting post 361 drives the lifting rod 31 to move and rotate inside the three-way faucet 1. The lifting rod 31 drives the valve core 32 to move synchronously. Through the cooperation between the lifting rod 31 and the valve core 32, the valve core 32 can open and close the water flow channel and adjust the opening degree.

[0036] The rubber ring 33 on the outside of the lifting rod 31 contacts the inside of the three-way faucet 1, and the sealing ring 34 at the bottom of the valve core 32 contacts the water outlet inside the three-way faucet 1. Through the cooperation of the rubber ring 33 and the sealing ring 34, water leakage from the gap is prevented, ensuring the water flow sealing performance.

[0037] In the adjusting assembly 35, the adjusting threaded ring 351 on the inner side of the water outlet seat 2 is threadedly connected to the adjusting threaded groove 352 on the top inner side of the three-way faucet 1. Through the cooperation of the adjusting threaded ring 351 and the adjusting threaded groove 352, the water outlet seat 2 and the three-way faucet 1 are fixedly connected. At the same time, the relative position of the two can be adjusted by rotating the handwheel 372 to initially adjust the position of the sealing ring 34 at the bottom of the valve core 32 to achieve medium flow control. When the adjusting threaded ring 351 is screwed out of the adjusting threaded groove 352, the sealing ring 34 is completely separated from the water outlet by pulling up the handwheel 372 to achieve large flow discharge.

[0038] The fastening grooves 362 on the outer wall of the mounting post 361 increase the friction between the mounting post 361 and the inner side of the fixing ring 371. Through the cooperation between the fastening grooves 362 and the fixing ring 371, the handwheel 372 is prevented from sliding relative to the mounting post 361 during the turning process, thus ensuring the stable transmission of operating force.

[0039] When water flow needs to be controlled, pull the handwheel 372 upwards. The lifting rod 31 drives the valve core 32 to move upwards and open the water flow channel. Rotate the handwheel 372. The lifting rod 31 drives the valve core 32 to rotate and adjust the channel opening to control the water flow. When closing, press the handwheel 372 downwards. The valve core 32 moves downwards and closes the channel.

[0040] Reference Figure 1 , Figure 4 and Figure 5 The filter mechanism 4 includes a limiting ring 41, the inner side of which is fixedly connected to the outer side of the water outlet seat 2. A filter cylinder 42 is provided on the top of the water outlet seat 2, and a steel mesh 43 is fixedly connected to the inner side of the filter cylinder 42. A disassembly spiral 44 is provided on the top of the outer wall of the water outlet seat 2. A disassembly threaded groove 45 is provided on the bottom of the inner side of the three-way faucet 1. An installation component 46 is provided on the bottom of the filter cylinder 42. The installation component 46 includes an installation stud 461, the top of which is fixedly connected to the bottom of the filter cylinder 42. An installation seat 462 is fixedly connected to the top of the water outlet seat 2. An observation component 47 is provided on the front side of the three-way faucet 1. The observation component 47 includes an observation window 471, the observation window 471 is fixedly connected to the front side of the three-way faucet 1, and an observation window 472 is fixedly connected to the front side of the filter cylinder 42.

[0041] Specifically, when the filter mechanism 4 is working, the filter cartridge 42 is fixed to the water outlet seat 2 through the mounting component 46. The mounting stud 461 of the mounting component 46 cooperates with the mounting seat 462 on the top of the water outlet seat 2 to stably fix the filter cartridge 42 on the top of the water outlet seat 2. Through the cooperation of the mounting stud 461 and the mounting seat 462, it is ensured that the filter cartridge 42 will not shift under the impact of water flow.

[0042] The steel mesh 43 inside the filter cartridge 42 intercepts impurities in the water flow. When the water flows through the filter cartridge 42, the impurities are blocked inside the filter cartridge 42 by the steel mesh 43. The filtered water continues to flow downward. Through the cooperation of the steel mesh 43 and the filter cartridge 42, the impurities in the water flow are filtered, and the quality of the effluent is improved.

[0043] The limiting ring 41 on the outside of the water outlet seat 2 contacts the filter cartridge 42, restricting the installation position of the filter cartridge 42 and preventing the filter cartridge 42 from shifting during installation, which would reduce the filtration effect. Through the cooperation between the limiting ring 41 and the filter cartridge 42, the filter cartridge 42 is ensured to be installed in the preset position.

[0044] The observation component 47 on the front side of the tee tap 1 assists in monitoring the filtration status. The outer observation window 471 is fixed on the front side of the tee tap 1, and the inner observation window 472 is fixed on the front side of the filter cartridge 42. The operator can directly observe the accumulation of impurities on the steel mesh 43 through the outer observation window 471 and the inner observation window 472. By coordinating the outer observation window 471 and the inner observation window 472, it can be determined whether the filter mechanism 4 needs to be disassembled and cleaned.

[0045] When the filter mechanism 4 needs to be disassembled and cleaned, use the disassembly spiral 44 on the top of the outer wall of the water outlet seat 2 and the disassembly threaded groove 45 on the bottom of the inner side of the tee faucet 1 to rotate the water outlet seat 2 with a tool to disengage the disassembly spiral 44 from the disassembly threaded groove 45. After removing the water outlet seat 2, unscrew the connection between the mounting stud 461 and the mounting base 462 to remove the filter cartridge 42 and clean the steel mesh 43. After cleaning, reconnect the mounting stud 461 and the mounting base 462, align the disassembly spiral 44 of the water outlet seat 2 with the disassembly threaded groove 45 and rotate to fix it, thus completing the reinstallation of the filter mechanism 4.

[0046] Working principle: The operation of the flow mechanism 3 controls the water flow and adjusts the water flow rate. Rotating the handwheel 372 transmits the rotational force to the mounting column 361 through the fixing ring 371. The mounting column 361 drives the lifting rod 31 to rotate inside the tee faucet 1. The lifting rod 31 drives the valve core 32 to rotate synchronously. The rotation of the valve core 32 changes the relative position with the water flow channel, thereby adjusting the opening of the water flow channel and realizing the control of the water flow rate. The fastening grooves 362 on the outer wall of the mounting column 361 increase the friction between the mounting column 361 and the inner side of the fixing ring 371, ensuring that the fixing ring 371 and the mounting column 361 will not slide relative to each other during the turning of the handwheel 372, ensuring stable transmission of operating force.

[0047] The rubber ring 33 fixedly connected to the outside of the lifting rod 31 is in close contact with the inside of the three-way faucet 1. The sealing ring 34 at the bottom of the valve core 32 is in close contact with the water outlet. Through the double sealing effect of the rubber ring 33 and the sealing ring 34, water leakage is prevented from the gap between the lifting rod 31 and the three-way faucet 1, and the gap between the valve core 32 and the water outlet. The adjusting thread ring 351 of the adjusting component 35 is fixedly connected to the inside of the water outlet seat 2. It is threadedly connected to the adjusting thread groove 352 opened on the top of the inside of the three-way faucet 1. When the handwheel 372 is rotated, the water outlet seat 2 can be driven to rotate synchronously, so that the adjusting thread ring 351 rotates in the adjusting thread groove 352. By turning the handwheel in and out, the relative position of the outlet seat 2 and the three-way faucet 1 is adjusted, initially changing the position of the valve core 32 to achieve medium flow control. When the adjusting thread ring 351 is completely turned out of the adjusting thread groove 352, the handwheel 372 is pulled upwards to completely remove the sealing ring 34 at the bottom of the valve core 32 from the outlet. At this time, the water flow channel is fully opened to achieve large flow discharge. When the water flow is turned off, the handwheel 372 is pressed downwards. The handwheel 372 drives the lifting rod 31 to move down through the fixing ring 371 and the mounting column 361. The lifting rod 31 drives the valve core 32 to move down synchronously until the sealing ring 34 completely blocks the outlet and cuts off the water flow.

[0048] Next, the water flows into the filter mechanism 4. The filter cartridge 42 is fixed to the top of the water outlet seat 2 by the mounting component 46. The top of the mounting stud 461 of the mounting component 46 is fixedly connected to the bottom of the filter cartridge 42. It is threadedly engaged with the mounting seat 462 fixedly connected to the top of the water outlet seat 2 to stably fix the filter cartridge 42. The limiting ring 41 fixedly connected to the outside of the water outlet seat 2 contacts the bottom of the filter cartridge 42 to limit the installation height and horizontal position of the filter cartridge 42, ensuring that the filter cartridge 42 is installed in the preset position and avoiding displacement that affects the filtration effect.

[0049] Water flows into the filter cartridge 42 from the three-way tap 1. The steel mesh 43 fixedly connected to the inside of the filter cartridge 42 filters the water. Impurities in the water are intercepted by the steel mesh 43 inside the filter cartridge 42. The filtered clean water continues to flow downward and flows out through the bottom of the outlet seat 2. The operator can directly observe the accumulation of impurities on the steel mesh 43 inside the filter cartridge 42 through the observation window 471 fixedly connected to the front of the three-way tap 1 and the observation window 472 fixedly connected to the front of the filter cartridge 42. When a large amount of impurities are found, it can be determined that the filter mechanism 4 needs to be disassembled and cleaned.

[0050] When the filter mechanism 4 needs to be disassembled and cleaned, rotate the water outlet seat 2 to gradually disengage the disassembly spiral 44 on the top of the outer wall of the water outlet seat 2 from the disassembly threaded groove 45 on the bottom of the inner side of the tee faucet 1. Then remove the water outlet seat 2 from the bottom of the tee faucet 1. Next, twist the filter cartridge 42 to unscrew the mounting stud 461 at the bottom of the filter cartridge 42 from the mounting seat 462 on the top of the water outlet seat 2. After removing the filter cartridge 42, clean the impurities accumulated on the steel mesh 43. After cleaning, align the mounting stud 461 with the mounting seat 462 and rotate it to fix it. Then align the disassembly spiral 44 of the water outlet seat 2 with the disassembly threaded groove 45 of the tee faucet 1 and rotate the water outlet seat 2 to make the two fully fit and fix it, thus completing the reinstallation of the filter mechanism 4.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
