Technical Field

[0001] The invention relates to the technical field of faucets, and in particular to a faucet with adjustable water outlet pressure. Background Art

[0002] A faucet is a device used to control water flow. It is usually installed at the end of a water pipe. The water flow can be turned on or off by rotating, pulling or pressing, and the water flow rate can be adjusted. It is like a "switch" for water flow, allowing people to easily obtain domestic water, such as for washing hands, washing vegetables, taking a bath, etc. The faucet is updated very quickly, from the old cast iron process to the electroplated knob type, and then to the stainless steel single temperature single control. Now with the development of science and technology, the material of the faucet is constantly improving, and more durable materials such as stainless steel and plastic have appeared. More and more consumers will consider the material, function, shape and other aspects when purchasing faucets; When using a faucet, the water flow rate is often adjusted for use.

There are multiple adjusting circular holes 305, and the multiple adjusting circular holes 305 are evenly distributed on the circular rotating plate 302. When in use, water flows into the bottom of the filter device 5, passes through the pressure regulating device 3 after being filtered by the filter device 5, and the pressure regulating device 3 adjusts the water pressure of the faucet by changing the passing area of ​​the water flow. The water flow after the water pressure is adjusted enters the concave faucet 1.

[0013] For the second embodiment, please refer to Figure 1-Figure 8The present invention provides a faucet with adjustable water outlet pressure: the hole cleaning device 4 comprises a side connecting rod 401, one end of the side connecting rod 401 is fixedly connected to a fixed circular plate 402, the top of the fixed circular plate 402 is fixedly connected to a stretching spring 403, the top of the stretching spring 403 is fixedly connected to a circular pressing plate 404, the bottom of the circular pressing plate 404 is fixedly connected to a circular penetrating rod 405, an annular wave plate 406 is sleeved and fixedly connected to the outer side of the circular penetrating rod 405, and an outer surface of the annular wave plate 406 is provided with a wave surface arc hole 407, one end of the side connecting rod 401 away from the fixed circular plate 402 is fixedly connected to the outer side of the concave faucet 1, the bottom of the circular penetrating rod 405 penetrates the fixed circular plate 402 and is slidably connected to the fixed circular plate 402, a plurality of wave surface arc holes 407 are provided, and the plurality of wave surface arc holes 407 are evenly distributed on the surface of the annular wave plate 406; The filtering device 5 includes a water-passing concave shell 501, the top of the water-passing concave shell 501 is connected to a water-passing pipe 502, the inner wall of the water-passing concave shell 501 is fixedly connected to a built-in circular plate 503, the top of the built-in circular plate 503 is provided with a filtering circular hole 504, the bottom of the built-in circular plate 503 is fixedly connected to a conical bottom block 505, the bottom of the built-in circular plate 503 is fixedly connected to an annular concave plate 506, the outer side of the annular concave plate 506 is fixedly connected to an arc surface circular hole 507, the top of the water-passing pipe 502 is connected to the bottom of the water-passing ring plate 301, a plurality of filtering circular holes 504 are provided, and the plurality of filtering circular holes 504 are distributed on the built-in circular plate 503, a plurality of arc surface circular holes 507 are provided, and the plurality of arc surface circular holes 507 are distributed on the outer side of the annular concave plate 506, and the arc surface circular holes The aperture size of 507 is the same as the aperture size of the filtering circular hole 504. When in use, after the circular rotating plate 302 has been used for a long time, the circular pressing plate 404 is manually pressed downward to move it. When the circular pressing plate 404 moves downward, the extension spring 403 at the bottom is compressed, and at the same time, the circular penetration rod 405 at the bottom is driven to penetrate the fixed circular plate 402 and move downward together. When the circular penetration rod 405 moves downward, it drives the outer annular wave plate 406 to move downward together. When the annular wave plate 406 moves downward to contact the top surface of the circular rotating plate 302, it is affected by the thrust and bends upward and enters the adjusting circular hole 305, and is in contact with the inner wall of the adjusting circular hole 305 at all times. The annular wave plate 406 that is in contact with the inner wall of the adjusting circular hole 305 at all times scrapes the inner wall of the adjusting circular hole 305 when it moves downward. The circular wave plate 406 is cleaned by opening a plurality of wave surface arc holes 407 on the surface of the circular wave plate 406 to facilitate the passage of granular impurities. The circular penetration rod 405 penetrating the fixed circular plate 402 slides and limits the circular pressure plate 404 elastically connected to the top. After the circular wave plate 406 has cleaned the inside of the adjusting circular hole 305, the circular pressure plate 404 can be released from its pressure. At this time, the extension spring 403 loses its pushing force and pushes the circular pressure plate 404 and the circular penetration rod 405 upward together through the extension force. The circular pressure plate 404 is pushed upward and reset through the extension force of the extension spring 403, so that the circular wave plate 406 moves to the top of the adjusting circular hole 305 for reuse. The water flows into the water-passing concave shell 501, contacts the surface of the conical bottom block 505, and flows along the conical bottom block 505. The conical inclined surface is diffused and directed to the position where the filtering circular hole 504 is opened at the bottom of the built-in circular plate 503. At the same time, a part of the water flow that fails to pass through the filtering circular hole 504 is directed to the annular concave plate 506. At this time, the water flow passes through the filtering circular hole 504 and enters the upper part of the built-in circular plate 503, and then enters the water pipe 502 from the water concave shell 501, and then enters the water passing ring plate 301 from the water passing pipe 502. By opening a plurality of filtering circular holes 504 on the built-in circular plate 503 to block particulate impurities and facilitate the passage of water, and by providing a conical bottom block 505 at the bottom of the built-in circular plate 503 to diffusely guide the water flow, the water flow directed to the annular concave plate 506 flows along the arc path of the annular concave plate 506 to the position where the arc surface circular hole 507 is opened.By opening a plurality of arc-shaped circular holes 507 on the surface of the annular concave plate 506 to block the particle impurities and facilitate the water flow to pass through, the annular concave plate 506 is arranged at the bottom of the built-in circular plate 503 near the outer side to collect the particle impurities in the water flow.

[0014] When the present invention is in operation, water flows into the filter device 5 from the bottom, passes through the filter device 5, and then passes through the pressure regulating device 3. The pressure regulating device 3 adjusts the water pressure of the faucet by changing the water flow passing area. The water flow after the water pressure is adjusted enters the concave faucet 1. At this time, the valve 2 is turned to open the water flow passage. The water flow after the pressure adjustment can be sprayed out from the concave faucet 1. After long-term use, the shell can press the hole cleaning device 4 to prevent blockage and clean the circular hole for adjusting the water pressure. The filtered water flows from the bottom of the water-passing ring plate 301 through the adjusting circular hole 305 and then enters the concave faucet 1 from the top of the water-passing ring plate 301. When it is necessary to adjust the water pressure of the water flow, it is only necessary to select the circular rotating plate 302 that needs to be adjusted. The circular rotating rod 303 is then rotated to drive the circular rotating plate 302 at the bottom to rotate until the selected adjusting circular hole 305 on the circular rotating plate 302 is rotated to the center of the water-passing ring plate 301. At this time, the water flow will be affected by the change in the aperture size of the adjusting circular hole 305, resulting in a change in the water flow rate and a change in the water outlet pressure. The water outlet pressure is adjusted by setting a plurality of adjusting circular holes 305 with different aperture sizes. When the circular rotating plate 302 rotates, the top and bottom surfaces are always in contact with the arc-shaped sponge block 306. When the circular rotating plate 302 rotates out of the circular side groove 304, the arc-shaped sponge block 306 absorbs the moisture attached to its surface. When the circular rotating plate 302 rotates into the circular side groove 304, the arc-shaped sponge block 306 absorbs the moisture attached to its surface The dust particles and debris are wiped away by wiping. When the arc sponge block 306 absorbs water for a long time to a saturated state and gradually overflows water droplets, the concave slider 308 is driven to rotate around the annular groove 307 by pushing the arc connecting rod 309. The arc connecting rod 309 also drives the inclined push plate 310 at one end to push and drain the arc sponge block 306. At this time, the discharged water can be collected under the water-passing ring plate 301 for secondary utilization. The inclined push plate 310 moving in the annular path pushes and drains the arc sponge block 306. After the circular rotating plate 302 has been used for a long time, the circular pressing plate 404 is manually pressed downward to move it. When the circular pressing plate 404 moves downward, the extension spring 403 at the bottom is compressed, and the circular penetration rod 403 at the bottom is driven at the same time. The circular rod 405 penetrates the fixed circular plate 402 and moves downward together. When the circular rod 405 moves downward, the outer annular wave plate 406 moves downward together. When the annular wave plate 406 moves downward to contact the top surface of the circular rotating plate 302, it is bent upward by the thrust and enters the adjusting circular hole 305 and contacts the inner wall of the adjusting circular hole 305 all the time. The annular wave plate 406 that contacts the inner wall of the adjusting circular hole 305 all the time performs a scraping cleaning on the inner wall of the adjusting circular hole 305 when moving downward. By opening a plurality of wave surface arc holes 407 on the surface of the annular wave plate 406, it is convenient for granular impurities to pass through. The circular rod 405 that penetrates the fixed circular plate 402 performs a sliding limit on the circular pressing plate 404 elastically connected to the top. After the annular wave plate 406 finishes cleaning the inside of the adjusting circular hole 305,The circular pressing plate 404 can be released from the pressing force, and the extension spring 403 loses its pushing force and pushes the circular pressing plate 404 and the circular penetration rod 405 upward together through the extension force, and the circular pressing plate 404 is pushed upward and reset by the extension force of the extension spring 403, so that the annular wave plate 406 moves to the top of the adjustment hole 305 for easy reuse, and the water flows into the water-passing concave shell 501 and contacts the surface of the conical bottom block 505 and is diffused and guided along the conical inclined surface of the conical bottom block 505 to the position where the filtering hole 504 is opened at the bottom of the built-in circular plate 503, and at the same time, a part of the water that fails to pass through the filtering hole 504 is guided into the annular concave plate 506, and at this time, the water flows through the filtering hole 504 and enters the top of the built-in circular plate 503 from the water-passing concave shell 501. The concave shell 501 enters the water pipe 502, and then enters the water ring plate 301 from the water pipe 502. A plurality of filtering circular holes 504 are provided on the built-in circular plate 503 to block the particle impurities and facilitate the water flow to pass through. A conical bottom block 505 is provided at the bottom of the built-in circular plate 503 to divert the water flow in a diffuse manner. The water flow diverted into the annular concave plate 506 flows along the arc path of the annular concave plate 506 to the position where the arc surface circular hole 507 is provided. A plurality of arc surface circular holes 507 are provided on the surface of the annular concave plate 506 to block the particle impurities and facilitate the water flow to pass through.
