Description

Technical Field

[0001] The invention relates to the technical field of faucets, and in particular to a high-sealing multi-stage constant-flow faucet. Background Art

[0002] As a device that plays an extremely important role in our daily life, the faucet meets people's water needs in various occasions by precisely controlling the opening and closing of the water flow and adjusting the flow rate. Whether it is washing hands, washing vegetables, bathing or cleaning the home, the faucet has become an indispensable part of our lives with its convenience and practicality. The sophistication of its design and the perfection of its functions are not only directly related to the user experience, but also to a great extent affect the conservation and rational use of water resources. A well-designed and fully functional faucet can help us effectively reduce unnecessary waste of water resources while ensuring ease of use, thereby playing a role in protecting the environment and promoting sustainable development in daily life.

[0003] The Chinese patent discloses a highly sealed multi-stage constant flow faucet (authorization announcement number CN117967860B). The patented technology sets a first adjustment component in the valve body, and drives the seal to move up and down through the clamping tube and other components by rotating the double-layer knob to achieve graded constant flow adjustment through the constant flow hole and the first sealing cylinder, and partially blocks the airflow passing through the pressure guide component to prevent the sealing disk from moving upward out of the first sealing cylinder due to water pressure when it is not adjusted, thereby avoiding the failure of constant flow; and through the conical shape of the conical cover, the baffle plate and the reset filling block on the side of the baffle plate, the airflow is quickly returned to the lower cavity of the sealing groove through the flow channel, so as to realize the rapid downward movement of the piston rod, realize the rapid closing of the first adjustment component, and avoid dripping and other phenomena.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the water flow control of traditional faucets mainly relies on knob valves. When the faucet needs to be opened and closed frequently, the user must constantly adjust the knob to control the water flow, which is particularly inconvenient when washing hands or vegetables in daily life, because the faucet cannot achieve the function of being turned on and used immediately. Therefore, the user has to operate the faucet repeatedly, which is not only cumbersome, but also when washing hands, the soapy fingers touching the faucet knob may contaminate the faucet knob. When the faucet is turned off after rinsing the hands, the soap bubbles remaining on the faucet may contaminate the user's hands again, which not only leads to poor hand washing effect of the user, but also may cause the faucet to be contaminated, requiring additional rinsing, thereby reducing the convenience of the faucet in daily use. Summary of the invention

[0005] The technical problem to be solved by the present invention is that the prior art has the disadvantage that frequent adjustment of the faucet knob affects the use effect. For this reason, we propose a high-sealing multi-stage constant-flow faucet.

[0014] Technical effects and advantages of the present invention: In the present invention, when the user opens the main valve, water will flow into the water flow pipe and be introduced into the connecting pipe and enter the conical pipe. The user uses his hand to push the second push rod to drive the first push rod, thereby pushing the gravity ball to move upward and away from the water outlet of the conical pipe. In this way, the user can adjust the water output of the conical pipe according to needs.

[0015] If continuous water discharge is required, the gravity ball can be moved up to a predetermined position, and then the slide bar is rotated to insert the slide plate into the oblique groove to ensure that the gravity ball is located at the top of the conical tube and maintain the conical tube in an open state.

[0019] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figure 1 - Figure 5As shown, the present invention provides a technical solution: a high-sealing multi-stage constant-flow faucet, comprising a main valve 1, a water flow tube 2 is installed on the top of the main valve 1, a connecting tube 3 is installed at the water outlet of the water flow tube 2, a conical tube 4 is fixedly connected to the bottom of the connecting tube 3, a bracket 5 is fixedly connected to the inner wall of the connecting tube 3, a sleeve 6 is fixedly connected to the top of the bracket 5, and a constant-flow component is arranged inside the sleeve 6. In daily use of the main valve 1 and the water flow tube 2, when the water flow tube 2 is in an open state, the constant-flow component is arranged to constant the flow of water discharged from the water flow tube 2 when the main valve 1 is opened, and the water flow tube 2 can be closed and opened at any time according to the use demand without adjusting the rotation angle of the main valve 1, thereby reducing the frequent adjustment of the water flow tube 2 during daily hand washing and vegetable washing.

[0021] Reference Figure 1 - Figure 6 As shown, in this embodiment: the flow-regulating component includes a slide bar 7 slidably connected to the middle part of the bracket 5, a slide plate 8 is fixedly connected to the surface of the slide bar 7, the slide plate 8 is slidably connected to the inner wall of the sleeve 6, a gravity ball 9 is fixedly connected to the bottom of the slide bar 7, a first push rod 10 is fixedly connected to the bottom of the gravity ball 9, a second push rod 11 is arranged at the bottom of the first push rod 10, arc grooves 12 are provided on both sides of the sleeve 6, both ends of the slide plate 8 are slidably connected to the inner wall of the arc groove 12, and an oblique groove 13 is provided on the top of the arc groove 12. When the user opens the main valve 1 to the maximum, the water flow guided out of the water flow pipe 2 is guided to the conical pipe 4 through the connecting pipe 3, and the surface of the gravity ball 9 is The design of the solid stainless steel center of the silicone material makes the gravity ball 9 always located at the bottom of the conical tube 4 due to its own weight, and the surface is tightly fitted with the inner wall of the conical tube 4 to block the water outlet of the conical tube 4. When people need to rinse after using soap, they only need to push the second push rod 11 upward by hand to drive the first push rod 10 to move upward to push the gravity ball 9 gradually away from the water outlet at the bottom of the conical tube 4, so that the conical tube 4 can discharge water through the gap on the outside of the gravity ball 9, rinse the second push rod 11 and the user's hands at the bottom thereof, and then the user pushes the gravity ball 9 to a horizontal height position in the conical tube 4 to achieve precise control of the water flow rate discharged from the conical tube 4.

[0022] When the user needs to use water for a long time, the first push rod 10 and the second push rod 11 are pushed upward to drive the gravity ball 9 to move upward to the specified position, so that the gravity ball 9 moves upward and pushes the slide bar 7 to drive the slide plate 8 to slide along the inner wall of the arc groove 12 opened on both sides of the sleeve 6. When the slide plate 8 slides to the top on the inner wall of the arc groove 12, the second push rod 11 is rotated to drive the slide bar 7 and the slide plate 8 to rotate, so that the two ends of the slide plate 8 rotate to the oblique groove 13, thereby fixing the gravity ball 9 at the top position of the inner wall of the conical tube 4, so that the long-term conical tube 4 is in an open state, so that the user can use water for a long time. In daily use, the device does not need to frequently adjust the main valve 1 to control the water output, and the water output can be controlled at any time, so that the user can use it as needed, which reduces the need to close the knob and reopen it when applying soap during the daily hand washing process, thereby generating a flushing gap, and avoids the hand soap foam caused by frequent adjustment of the main valve 1 adhering to the surface of the main valve 1 to cause pollution and contact with the washed hands again.

[0023] Reference Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment: the top of the connecting pipe 3 is connected to the water flow pipe 2 by threads, and an installation groove 14 is opened on the top of the connecting pipe 3. A filter screen 15 is arranged at the bottom of the inner wall of the installation groove 14, and a sealing ring 16 is arranged on the top of the filter screen 15. Through the threaded connection between the water flow pipe 2 and the connecting pipe 3, it is convenient for the user to disassemble the connecting pipe 3 and the conical pipe 4, and regularly clean the internal structure of the conical pipe 4 to reduce residual dirt and sediment accumulation, and avoid affecting the operation of the components. The filter screen 15 and the sealing ring 16 are set to ensure the sealing of the water flow pipe 2 and the connecting pipe 3 when connected to prevent water leakage, and then the water flow led out of the water flow pipe 2 is filtered through the filter screen 15 to reduce the risk of sediment in the water entering the connecting pipe 3, which not only ensures the health of water use, but also prevents sediment in the water from entering the conical pipe 4 and interfering with the operation between components, and avoids the contamination of foreign matter on the surface of the gravity ball 9 affecting the sealing effect.

[0024] Reference Figure 3 As shown, in this embodiment: the inner wall of the conical tube 4 is fixedly connected with a silicone ring 17, the inner diameter of the silicone ring 17 is an arc-shaped structure, and the gravity ball 9 is placed in the middle of the silicone ring 17. Through the setting of the silicone ring 17, the silicone ring 17 can be deformed when the silicone material characteristics of the silicone ring 17 come into contact with the gravity ball 9, thereby limiting the gravity ball 9 in the middle position of the silicone ring 17 and fitting tightly with the surface of the gravity ball 9, thereby improving the sealing effect of the gravity ball 9 on the bottom of the conical tube 4 and preventing the gravity ball 9 from leaking when not in use.

[0025] Reference Figure 4 and Figure 6As shown, in this embodiment: the top of the inner wall of the sleeve 6 is fixedly connected with a spring 18, and the bottom of the spring 18 is fixedly connected with an annular plate 19, and the annular plate 19 is sleeved on the outside of the slide rod 7. When the user pushes the gravity ball 9 upward to move, the gravity ball 9 drives the slide rod 7 and the slide plate 8 to move upward, and the slide plate 8 pushes the annular plate 19 upward to squeeze the spring 18 for contraction and accumulation of force. When the user releases the restraint on the gravity ball 9, the spring 18 is no longer restricted, and rebounds downward to drive the annular plate 19 to push the slide plate 8 and the slide rod 7 to move upward, and drives the gravity ball 9 to press down for reset, thereby ensuring that the gravity ball 9 is always in close fit with the bottom of the inner wall of the conical tube 4, further improving the sealing performance of the gravity ball 9 to the conical tube 4, and preventing cockroaches and the like from crawling into the conical tube 4 and causing pollution.

[0026] Reference Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment: a slide groove 20 is provided inside the slide bar 7, and a rotating rod 21 is slidably connected to the inner wall of the slide groove 20, and a work-shaped rotating plate 22 is fixedly connected to the top of the rotating rod 21. The work-shaped rotating plate 22 is rotatably connected to the center of the filter screen 15, and three scrapers 23 are fixedly connected to the top of the work-shaped rotating plate 22. The arc-shaped groove 12 is obliquely opened, so that when the slide plate 8 moves along the inner wall of the arc groove 12 and the oblique groove 13 in daily use, the slide bar 7 will follow the slide plate 8 to rotate at a certain angle, and then the rotating rod 21 sliding in the slide groove 20 makes the rotating rod 21 retract into the slide groove 20. At the same time, through the structure that the two ends of the slide groove 20 are matched with the two sides of the rotating rod 21, the rotating rod 21 can follow the slide rod 7 to move up and down and rotate with the slide rod 7, and drive the I-shaped rotating plate 22 to rotate, so that the I-shaped rotating plate 22 rotates at the center of the filter screen 15 and drives the scraper 23 to rotate and move in contact with the surface of the filter screen 15, so as to scrape off the foreign matter blocking the surface of the filter screen 15, crush it and dredge it, and prevent the mud and sand attached to the water from clogging the filter screen 15, so that the device can clean and dredge the filter screen 15 by itself in daily use, reducing the probability of water flow blockage.

[0027] Reference Figure 7As shown, in the present embodiment: a cross groove 24 is provided at the bottom of the first push rod 10, a negative magnet 25 is fixedly connected to the bottom of the first push rod 10, a positive magnet 26 is fixedly connected to the top of the second push rod 11, and plug plates 27 are fixedly connected on all sides of the top of the second push rod 11. By placing the second push rod 11 at the bottom of the first push rod 10, the plug plate 27 is inserted into the inner wall of the cross groove 24, and then the negative magnet 25 is magnetically connected to the positive magnet 26, so that the position of the second push rod 11 is fixed at the bottom of the first push rod 10, so that the first push rod 10 and the second push rod 11 are detachable. In daily use, when there is no need to frequently push the first push rod 10 and the second push rod 11 to adjust the position of the gravity ball 9, the second push rod 11 can be disassembled to reduce the second push rod 11 from blocking the use area of ​​the bottom of the conical tube 4, thereby making it more convenient for the conical tube 4 to derive the water flow.

[0028] Reference Figure 1 As shown, in the present embodiment: a casing 28 is fixedly connected to one side of the water flow tube 2, and the inner diameter of the casing 28 is matched with the diameter of the second push rod 11. After the user disassembles the second push rod 11, the second push rod 11 is inserted downward into the casing 28 so that the small ball at the top of the second push rod 11 is located at the top of the casing 28, thereby storing the second push rod 11 in the casing 28, so that the user can take it at any time and prevent the second push rod 11 from being lost after disassembly.

[0029] When the user opens the main valve 1 to the maximum, the water flow guided by the water flow pipe 2 is guided to the conical tube 4 through the connecting pipe 3. The gravity ball 9 is designed to be made of silicone material on the surface and solid stainless steel in the center, so that the gravity ball 9 is always located at the bottom of the conical tube 4 due to its own weight, and the surface is tightly fitted with the inner wall of the conical tube 4 to block the water outlet of the conical tube 4. When people need to rinse after using soap, they only need to push the second push rod 11 upward by hand to drive the first push rod 10 to move upward to push the gravity ball 9 gradually away from the water outlet at the bottom of the conical tube 4, so that the conical tube 4 can discharge water through the gap on the outside of the gravity ball 9, rinse the second push rod 11 and the hands of the user at its bottom, and then the user pushes the gravity ball 9 to a horizontal height position in the conical tube 4. Thereby, accurate control of the water flow rate of the tapered tube 4 is achieved. When the user needs to use water for a long time, the first push rod 10 and the second push rod 11 are pushed upward to drive the gravity ball 9 to move upward to the specified position, so that the gravity ball 9 moves upward and pushes the slide bar 7 to drive the slide plate 8 to slide along the inner wall of the arc groove 12 opened on both sides of the sleeve 6. When the slide plate 8 slides to the top on the inner wall of the arc groove 12, the second push rod 11 is rotated to drive the slide bar 7 and the slide plate 8 to rotate, so that the two ends of the slide plate 8 rotate into the oblique groove 13, thereby fixing the gravity ball 9 at the top position of the inner wall of the tapered tube 4, so that the long-term tapered tube 4 is in an open state, so that the user can use water for a long time, so that the device can be controlled at any time in daily use without frequently adjusting the main valve 1 to control the water output. Water is produced so that the user can take it as needed, which reduces the need to close the knob and then reopen it when applying soap during daily hand washing, thereby generating a flushing gap, and avoids frequent adjustment of the main valve 1, which causes soap foam on the hands to adhere to the surface of the main valve 1 and cause contamination, and then contact the washed hands again. The threaded connection between the water flow pipe 2 and the connecting pipe 3 is convenient for the user to disassemble the connecting pipe 3 and the tapered pipe 4, and regularly clean the internal structure of the tapered pipe 4 to reduce dirt residue and sediment accumulation to avoid affecting the operation of the components. The filter 15 and the sealing ring 16 are provided to ensure the sealing of the water flow pipe 2 when connected to the connecting pipe 3 to prevent water leakage, and then the water flow drawn out of the water flow pipe 2 is filtered through the filter 15 to reduce the sediment in the water from entering the connecting pipe 3. The risk of pipe 3 is not only guaranteed to be healthy for water use, but also prevents mud and sand in the water from entering the conical pipe 4 and interfering with the operation between components, and avoids foreign matter from contaminating the surface of the gravity ball 9 and affecting the sealing effect. The silicone ring 17 is set so that when the silicone material characteristics of the silicone ring 17 come into contact with the gravity ball 9, the silicone ring 17 can be deformed, and the gravity ball 9 is restricted to the middle position of the silicone ring 17 and fits tightly with the surface of the gravity ball 9, thereby improving the sealing effect of the gravity ball 9 on the bottom of the conical pipe 4 and preventing the gravity ball 9 from leaking when not in use. When the user pushes the gravity ball 9 upward to move, the gravity ball 9 drives the slide bar 7 and the slide plate 8 to move upward, and the slide plate 8 pushes the annular plate 19 upward to squeeze the spring 18 to contract and store force. When the user releases the restraint on the gravity ball 9,The spring 18 is no longer restricted, and rebounds downward to drive the annular plate 19 to push the slide plate 8 and the slide bar 7 upward, and drive the gravity ball 9 to press down to reset, ensuring that the gravity ball 9 is always in close contact with the bottom of the inner wall of the conical tube 4, further improving the sealing performance of the gravity ball 9 to the conical tube 4, and preventing cockroaches and the like from crawling into the conical tube 4 and causing pollution. The arc-shaped oblique opening of the arc groove 12 makes it possible for the slide plate 8 to move along the inner wall of the arc groove 12 and the oblique groove 13 in daily use, and the slide bar 7 will follow the slide plate 8 to rotate at a certain angle. Then, the rotating rod 21 slides in the chute 20, so that the rotating rod 21 is retracted into the chute 20. At the same time, through the structure that the two ends of the chute 20 are matched with the two sides of the rotating rod 21, the rotating rod 21 can follow the slide bar 7 to move up and down and rotate with the slide bar 7, and drive the I-shaped rotating plate 22 to rotate, so that the I-shaped rotating plate 22 rotates at the center of the filter screen 15 and drives the scraper 23 to rotate and move on the surface of the filter screen 15, so as to scrape off the foreign matter blocking the surface of the filter screen 15, crush and dredge it, and prevent water from getting in the filter screen 15. The silt attached to the filter 15 causes clogging of the filter screen 15, so that the device can automatically clean and dredge the filter screen 15 in daily use, reducing the probability of water flow blockage. By placing the second push rod 11 at the bottom of the first push rod 10, the plug plate 27 is inserted into the inner wall of the cross groove 24, and then the negative pole magnet 25 is connected to the positive pole magnet 26 by magnetic attraction, so that the position of the second push rod 11 is fixed at the bottom of the first push rod 10, so that the first push rod 10 and the second push rod 11 can be detached, and there is no need to frequently push the first push rod 11 in daily use. When the push rod 10 and the second push rod 11 adjust the position of the gravity ball 9, the second push rod 11 is disassembled to reduce the second push rod 11 blocking the use area at the bottom of the conical tube 4, so as to facilitate the use range of the conical tube 4 to guide the water flow. After the user disassembles the second push rod 11, the second push rod 11 is inserted downward into the sleeve 28 so that the small ball at the top of the second push rod 11 is located at the top of the sleeve 28, thereby storing the second push rod 11 in the sleeve 28, so that the user can take it at any time and prevent the second push rod 11 from being lost after disassembly.
