Description

Technical Field

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

[0002] A faucet is an important tool for controlling the water flow rate in daily life. To meet the basic needs of civil water pressure, a booster pump is usually installed in the urban water supply network during the water supply process. However, according to different actual usage situations, the water pressure requirements are also different. When the water pressure is insufficient during daily water use, the water flow rate will be slow, prolonging the water use time, thus affecting the cleaning efficiency and comfort. At the same time, if the water pressure is too high, the water will splash, which will also affect the use experience.

[0003] At present, faucets usually have fixed flow and fixed pressure water output, and cannot be freely adjusted according to usage requirements. When adjusting the water pressure of the faucet, only the size of the water outlet hole can be changed to adjust, and the method is relatively single and the adjustment effect usually cannot meet the usage requirements. Moreover, after long-term use, due to the too small water outlet hole, scale is likely to accumulate, affecting the use effect.

[0004] To solve the above problems, we made improvements and proposed a faucet with adjustable water pressure. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] The present invention provides a faucet with adjustable water pressure, including a mounting base, a faucet body, a handle body, and a handle. A plurality of spiral components for increasing the water flow rate are installed inside the mounting base. The spiral components are composed of a plurality of spiral blades with slots in the middle. An outlet cavity is installed on the front side of the handle body. An extension piece is slidably connected inside the outlet cavity. An elastic tube is connected inside the extension piece. A plurality of ventilation holes are provided on the side wall of the extension piece. A plurality of connecting rods and pressing pieces corresponding to the ventilation holes one by one are provided inside the extension piece;

[0007] A docking tube is installed on the front side of the extension piece. A rotating piece is rotatably connected inside the docking tube. Mesh components are coaxially and fixedly installed inside the rotating piece and the docking tube respectively. The mesh components are divided into a front mesh and a rear mesh. A plurality of water outlet holes are penetrated on the surfaces of the front mesh and the rear mesh. The positions and sizes of the water outlet holes of the front mesh and the rear mesh correspond to each other one by one. A water outlet pipe is threadedly connected to the front side of the extension piece.

[0008] As a preferred technical solution of the present invention, a chamber is provided inside the extension member. Both ends of the elastic tube are hermetically connected to the inlet and outlet at both ends of the chamber. A plurality of inner cavities are provided on both side surfaces of the chamber. A connecting frame is fixedly connected inside the inner cavity. The connecting rod and the connecting frame are hinged by a torsion spring. A spring is fixedly connected to the top of the connecting rod. The other end of the spring is fixedly connected to the inner surface of the inner cavity.

[0009] As a preferred technical solution of the present invention, a plurality of the inner cavities are all located above the ventilation holes. The pressing piece is fixedly installed at the bottom of the connecting rod. When the pressing piece fits with the inner wall of the chamber, the ventilation holes are sealed. The installation direction of the spring is opposite to the direction of the pressing piece. The elastic tube is made of rubber with a certain elasticity.

[0010] As a preferred technical solution of the present invention, a communicating chute and a water trough are provided inside the water outlet chamber. The extension member is slidably connected to the inside of the chute. A rack is fixedly connected to the rear side surface of the extension member. A gear set meshing with the rack is rotatably connected to the bottom of the water trough. A knob coaxially fixedly connected to the gear set is rotatably installed outside the water outlet chamber. A corrugated pipe is fixedly connected to the rear side of the extension member. The corrugated pipe is communicated with the elastic tube. The other end of the corrugated pipe is communicated with the faucet body.

[0011] As a preferred technical solution of the present invention, a reserved groove is provided on the surface of the docking pipe. A dial is fixedly installed on the outer surface of the rotating member. A waterproof gasket is provided at the connection between the rotating member and the docking pipe. A rubber ring is fixedly installed on the side surface of the front mesh piece. The front mesh piece is clamped to the inner surface of the docking pipe by the resistance of the rubber ring.

[0012] As a preferred technical solution of the present invention, the rear mesh piece is fixedly installed on the inner surface of the docking pipe. The threaded part at the rear of the water outlet pipe extends inward into the docking pipe and contacts the edge of the front mesh piece, so that the surfaces of the front mesh piece and the rear mesh piece are fitted. By rotating the rotating member, the alignment degree of the water outlet of the front mesh piece and the rear mesh piece is adjusted, that is, the water outlet size of the water outlet pipe is adjusted.

[0013] As a preferred technical solution of the present invention, a rotating rod is rotatably installed on the inner bottom surface of the installation base. A plurality of stabilizing frames are fixedly installed on the top of the rotating rod. The stabilizing frames are rotatably connected to the installation base. A plurality of the spiral components are respectively fixedly installed on the outer surface of the rotating rod. Water flows through the spiral fins and the intermediate groove between them, driving the rotating rod and the spiral components to rotate at a high speed, so that the water flow forms a spiral upward trend, increasing the water flow velocity.

[0014] As a preferred technical solution of the present invention, a water inlet is provided at the bottom of the installation base, the faucet body is fixedly installed on the top of the installation base, the handle body is connected to the top of the faucet body, a valve body for restricting water flow is installed inside the handle body, the handle is fixedly installed on the front surface of the handle body, the water outlet cavity is fixedly installed on the front side of the faucet body, and the water outlet cavity is communicated with both the inside of the faucet body and the installation base.

[0015] The beneficial effects of the present invention are:

[0016] 1. For this faucet with adjustable water pressure, when tap water enters the installation base from the pipe network, the water flow drives the rotating rod and the threaded components on its surface to rotate. At this time, the water flow passes through the inside of several spiral fins and the grooves between them, cutting the water flow and increasing the content of small bubbles inside it, thereby increasing the upward impact force of the water flow and realizing the preliminary pressurization of tap water;

[0017] 2. Rotating the knob can make the gear and rack drive the extension piece to slide inside the water outlet cavity. When the ventilation holes on the surface of the extension piece are all inside the water outlet cavity, when the water flow passes through the elastic tube, the gas inside it will be discharged from the gap between the extension piece and the water outlet cavity. And because the gap is too small, it is difficult for external gas to enter. The water continuously accumulates inside the elastic tube and expands it until the outer wall of the elastic tube squeezes the pressing piece to the ventilation hole. At this time, the air pressure inside the cavity is kept constant, and because the elastic force of the elastic tube continuously squeezes the water inside, the secondary pressurization of tap water is realized. Similarly, when the knob is turned counterclockwise, the extension piece can be slid out of the water outlet cavity. At this time, the external air pressure squeezes the air inside the cavity, which can not only relieve the pressure inside the elastic tube, but also reduce the water flow pressure when the water flow flows in the hose;

[0018] 3. By driving the rotating piece to rotate with the dial, the water outlet openings of the front mesh piece and the rear mesh piece are misaligned, so that the water outlet of the water flow can be reduced, realizing the three - time pressurization of the water flow. The threaded opening of the water outlet pipe restricts the movement of the mesh piece assembly, preventing it from being displaced by the water impact. Unscrewing the water outlet pipe can clean the mesh piece assembly and maintain its use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0031] Embodiment: As Figures 1-9 shown, a water pressure adjustable tap includes an installation base 1, a tap body 2, a handle body 3 and a handle 4. A plurality of spiral components 31 for increasing the water flow rate are installed inside the installation base 1. The spiral components 31 are composed of a plurality of spiral pieces 32 with intermediate grooves 33 opened therein. A water outlet cavity 5 is installed on the front side of the handle body 3. An extension part 6 is slidably connected inside the water outlet cavity 5. An elastic tube 13 is connected inside the extension part 6. A plurality of vent holes 22 are opened on the side wall of the extension part 6. A plurality of connecting rods 26 and pressing pieces 27 corresponding to the vent holes 22 one by one are arranged inside the extension part 6;

[0032] The front side of the extension piece 6 is installed with a docking pipe 20. A rotating piece 18 is rotatably connected inside the docking pipe 20. Mesh components 19 are coaxially and fixedly installed inside the rotating piece 18 and the docking pipe 20 respectively. The mesh component 19 is divided into a front mesh 1901 and a rear mesh 1902. A number of water outlets 29 are provided on the surfaces of the front mesh 1901 and the rear mesh 1902. The positions and sizes of the water outlets 29 of the front mesh 1901 and the rear mesh 1902 correspond to each other one by one. A water outlet pipe 7 is threadedly connected to the front side of the extension piece 6.

[0033] A chamber 12 is provided inside the extension piece 6. Both ends of the elastic tube 13 are hermetically connected to the two ends of the chamber 12 for inlet and outlet. A number of inner cavities 23 are provided on both side surfaces of the chamber 12. A connecting frame 25 is fixedly connected inside the inner cavity 23. The connecting rod 26 is hinged to the connecting frame 25 through a torsion spring. The top of the connecting rod 26 is fixedly connected with a spring 24. The other end of the spring 24 is fixedly connected to the inner surface of the inner cavity 23.

[0034] A number of inner cavities 23 are all located above the ventilation holes 22. A pressing piece 27 is fixedly installed at the bottom of the connecting rod 26. When the pressing piece 27 fits with the inner wall of the chamber 12, the ventilation holes 22 are sealed. The installation direction of the spring 24 is opposite to the direction of the pressing piece 27. The material of the elastic tube 13 is rubber with certain elasticity.

[0035] During daily use, affected by the spring 24 and the torsion spring of the connecting frame 25, the pressing piece 27 will not contact the inside of the chamber 12. When the ventilation holes 22 are all located inside the water outlet chamber 5, since the water flowing through the elastic tube 13 will discharge the gas inside the chamber 12 from the gap between the extension piece 6 and the water outlet chamber 5, and because the gap is too small, it is difficult for external gas to enter. The water continuously accumulates inside the elastic tube 13 and expands it. Its inner wall expands outwards and presses the pressing piece 27, making the pressing piece 27 closely adhere to the inner wall of the chamber 12 and blocking the ventilation holes 22, so that the air pressure inside the chamber 12 remains roughly stable, that is, the elastic tube 13 remains in a swollen state, squeezing the water inside it and increasing the water flow pressure.

[0036] A communicating chute 11 and a water trough 14 are provided inside the water outlet chamber 5. The extension piece 6 is slidably connected to the inside of the chute 11. A rack 16 is fixedly connected to the rear side surface of the extension piece 6. A gear set 17 meshing with the rack 16 is rotatably connected to the bottom of the water trough 14. A knob 10 coaxially and fixedly connected to the gear set 17 is rotatably installed outside the water outlet chamber 5. A bellows 15 is fixedly connected to the rear side of the extension piece 6. The bellows 15 is communicated with the elastic tube 13. The other end of the bellows 15 is communicated with the faucet main body 2.

[0037] Rotating the knob 10 can cause the gear set 17 to rotate, driving the movement of the rack 16, thereby adjusting the position of the extension member 6. When all the vent holes 22 on the surface of the extension member 6 are located inside the water outlet chamber 5, the air pressure inside the chamber 12 is stable, and the pressure on the surface of the elastic tube 13 is basically unchanged, thus maintaining the stability of the water flow pressure in this state. When the vent holes 22 are located outside the water outlet chamber 5, the chamber 12 is in communication with the external air pressure, reducing the pressure on the elastic tube 13.

[0038] The surface of the docking pipe 20 is provided with a reserved groove 21. A dial 28 is fixedly installed on the outer surface of the rotating member 18. A waterproof gasket is provided at the connection between the rotating member 18 and the docking pipe 20 to prevent water from overflowing from the connection. A rubber ring is fixedly installed on the side surface of the front mesh piece 1901, and the front mesh piece 1901 is clamped to the inner surface of the docking pipe 20 through the resistance of the rubber ring.

[0039] The rear mesh piece 1902 is fixedly installed on the inner surface of the docking pipe 20. The threaded part at the rear of the water outlet pipe 7 extends inward into the interior of the docking pipe 20 and contacts the edge of the front mesh piece 1901, making the surfaces of the front mesh piece 1901 and the rear mesh piece 1902 fit together. By rotating the rotating member 18, the alignment degree of the water outlet 29 of the front mesh piece 1901 and the rear mesh piece 1902 is adjusted, that is, the water output size of the water outlet pipe 7 is adjusted.

[0040] The rotating member 18 can be driven to rotate by the dial, causing the water outlets 29 of the front mesh piece 1901 and the rear mesh piece 1902 to be misaligned, thereby reducing the water outlet of the water flow and realizing the three - stage pressurization of the water flow. The threaded port of the water outlet pipe restricts the movement of the front mesh piece 1901 to prevent it from shifting under the impact of water. Unscrewing the water outlet pipe can clean the mesh component 19 and maintain its use effect.

[0041] A rotating rod 30 is rotatably installed on the inner bottom surface of the installation base 1. A plurality of stabilizing frames 8 are fixedly installed on the top of the rotating rod 30. The stabilizing frames 8 are rotatably connected to the installation base 1. A plurality of spiral components 31 are respectively fixedly installed on the outer surface of the rotating rod 30. The water flow passes through the spiral blades 32 and the intermediate groove 33 between them, driving the rotating rod 30 and the spiral components 31 to rotate at high speed, causing the water flow to form a spiral upward trend. The water flow passes through the inside of a plurality of spiral blades 32 and their intermediate grooves 33, cutting the water flow and increasing the content of small bubbles inside it, thereby increasing the upward impact force of the water flow, realizing the preliminary pressurization of the tap water, and increasing the water flow velocity.

[0042] The bottom of the installation base 1 is provided with a water inlet 9. The faucet main body 2 is fixedly installed on the top of the installation base 1. The handle body 3 is connected to the top of the faucet main body 2. A valve body for restricting the water flow is installed inside the handle body 3. The handle 4 is fixedly installed on the front side surface of the handle body 3. The water outlet chamber 5 is fixedly installed on the front side of the faucet main body 2. The water outlet chamber 5 is in communication with both the inside of the faucet main body 2 and the installation base 1, which are all common technical means in this field and will not be described in detail.

[0043] Working principle: When this kind of water pressure adjustable faucet is in use, water flow passes through the spiral vanes 32 and the slot 33 in the middle thereof, driving the rotating rod 30 and the spiral assembly 31 to rotate at a high speed, so that the water flow forms a spiral upward trend. The water flow passes through the inside of a number of spiral vanes 32 and the slots 33 therebetween, cutting the water flow while increasing the content of small bubbles inside it, thereby increasing the upward impact force of the water flow and realizing the preliminary pressurization of tap water;

[0044] During daily use, affected by the spring 24 and the torsion spring of the connecting frame 25, the pressing piece 27 will not contact the inside of the chamber 12. When the vent holes 22 are all located inside the water outlet chamber 5, since the water flow will discharge the gas inside the chamber 12 from the gap between the extension piece 6 and the water outlet chamber 5 during the process of passing through the elastic tube 13, and because the gap is too small, it is difficult for external gas to enter. Water continuously accumulates inside the elastic tube 13 and expands it. Its inner wall expands outward and presses the pressing piece 27, causing the pressing piece 27 to closely adhere to the inner wall of the chamber 12 and block the vent holes 22, keeping the air pressure inside the chamber 12 generally stable, that is, the elastic tube 13 remains in a swollen state, squeezing the water inside it and increasing the water flow pressure. Rotating the knob 10 can make the gear set 17 rotate, driving the movement of the rack 16, thereby adjusting the position of the extension piece 6. When the vent holes 22 on the surface of the extension piece 6 are all located inside the water outlet chamber 5, the air pressure inside the chamber 12 is stable, and the pressure on the surface of the elastic tube 13 is basically unchanged, thus maintaining the stability of the water flow pressure in this state. When the vent holes 22 are located outside the water outlet chamber 5, the chamber 12 is in communication with the external air pressure, reducing the pressure on the elastic tube 13;

[0045] The turning piece 18 can be driven to rotate through the paddle, so that the water outlet 29 of the front mesh piece 1901 and the rear mesh piece 1902 are misaligned, that is, the water outlet of the water flow can be reduced, realizing the three - stage pressurization of the water flow. The threaded port of the water outlet pipe restricts the movement of the front mesh piece 1901 to prevent it from being displaced by the water impact. Unscrewing the water outlet pipe can clean the mesh assembly 19 and maintain its use effect.

[0046] Finally, it should be noted that: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
