Description

Technical Field

[0001] This invention relates to the field of high-quality drinking water technology, and specifically to a stainless steel pipe for preventing water stagnation in high-quality drinking water. Background Technology

[0002] High-quality drinking water anti-stagnant stainless steel pipes are stainless steel pipes specially designed for direct drinking water systems. Through material properties and structural design, they fundamentally prevent the formation of stagnant, non-flowing water in the pipes, thereby eliminating the growth of pathogens such as bacteria and Legionella and ensuring the long-term hygiene and safety of drinking water.

[0003] In existing technologies, stainless steel pipes for preventing water stagnation in high-quality drinking water do not have a diversion design during use. The diverted water flow cannot drive the valves to rotate, resulting in the valves not being able to effectively move the water flow. This leads to insufficient water discharge and easy residue buildup. When the flow stops, the buoyancy ball and return spring cannot be used to make the diverted water flow back, affecting the anti-stagnation function. Furthermore, the valves cannot be manually rotated synchronously, making it impossible to completely discharge the water flow, thus reducing the anti-stagnation efficiency and flow guiding efficiency.

[0016] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1 like Figures 1 to 9 As shown, a stainless steel pipe for preventing stagnant water in high-quality drinking water includes: a first pipe body 1, a connecting pipe 4 connected to the rear end of the first pipe body 1, a second pipe body 7 connected to the rear side of the connecting pipe 4, and the rear side of the second pipe body 7 is closed; a water outlet pipe 8 connected to the bottom of the second pipe body 7; an arc-shaped pipe 5 connected to the top of the second pipe body 7; a vertical pipe 6 connected to the top of the arc-shaped pipe 5, and the top of the vertical pipe 6 is closed; an L-shaped pipe 9 connected to the top of the first pipe body 1, and the rear end of the L-shaped pipe 9 is connected to the interior of the vertical pipe 6.

[0018] By cooperating with each other, the first pipe body 1, the connecting pipe 4, the L-shaped pipe 9, the arc-shaped pipe 5, the second pipe body 7, and other components, a diversion structure is set up. The diverted water flow drives the petals to rotate, effectively agitating the water flow, reducing water residue, and improving the anti-stagnant water performance.

[0019] In this embodiment, the top of the connecting pipe 4 is connected to a sealing pipe 15, and the top of the sealing pipe 15 is closed. The top of the sealing pipe 15 is fixedly connected to a bearing, and a rotating shaft 16 is fixedly inserted into the inner cavity of the bearing. The top end of the rotating shaft 16 extends into the connecting pipe 4 and is connected to a flap 26. The top end of the rotating shaft 16 passes through the inner ring of the first bearing and is connected to a rotating column 18.

[0020] A circular block 23 is connected inside the vertical tube 6, and a movable column 24 is slidably connected inside the vertical tube 6 near the top. A buoyancy ball 25 is installed at the bottom of the movable column 24. A through hole is opened at the top of the vertical tube 6, and a lifting column 19 is inserted through the through hole. The bottom end of the lifting column 19 is connected to the top of the movable column 24. A buffer spring 27 is installed on the outer sleeve of the lifting column 19. The top and bottom ends of the buffer spring 27 are respectively connected to the top of the inner cavity of the vertical tube 6 and the top of the movable column 24.

[0021] The right side of the lifting column 19 is connected to a first L-shaped column 22, and the bottom end of the first L-shaped column 22 is connected to a second L-shaped column 13. The rotating column 18 is provided with a spiral groove 17 that matches the second L-shaped column 13. The vertical tube 6 is fitted with an annular magnet 20, and the annular magnet 20 is fitted with a limiting ring 21. The right side of the limiting ring 21 is connected to the first L-shaped column 22. The rear end of the first tube body 1 and the front end of the second tube body 7 are respectively connected to a first flange 3. The front and rear ends of the connecting tube 4 are respectively connected to a second flange 28. A fastening screw 29 is connected between the first flange 3 and the second flange 28.

[0022] Through the cooperation of components such as movable column 24, buoyancy ball 25, lifting column 19 and buffer spring 27, when the flow stops, the elasticity of buoyancy ball 25 and return spring 27 is used to realize the return of diverted water flow, ensuring that the water flow is fully discharged and optimizing the flow guiding effect. In this embodiment, a sealing ring 2 is attached to the front side of the first tube body 1, and a threaded tube 10 is threadedly fitted onto the outside of the first tube body 1. A first protective tube 12 is fitted onto the outer sleeve of the sealing tube 15, and the bottom of the first protective tube 12 is connected to the top of the connecting tube 4. A first movable groove 11 matching the second L-shaped column 13 is opened on the right side of the first protective tube 12. A second protective tube 14 is fitted onto the outer sleeve of the vertical tube 6, and the bottom end of the second protective tube 14 is connected to the top of the second tube body 7. A round hole matching the L-shaped tube 9 is opened on the second protective tube 14, and a second movable groove 30 matching the second L-shaped column 13 is opened on the right side of the second protective tube 14.

[0023] Through the cooperation of components such as the first L-shaped column 22, the limiting ring 21, the annular magnet 20, the second L-shaped column 13, the rotating column 18, and the spiral groove 17, the synchronous design allows for the manual rotation of the flap 26, ensuring complete water discharge and further improving the efficiency of preventing stagnant water and guiding flow.

[0024] In use, the water is first connected to the faucet or other water inlet through the sealing ring 2, the first pipe body 1, and the threaded pipe 10. Then, the faucet or water valve is turned on and the water flows into the first pipe body 1. The water is then diverted to the vertical pipe 6 through the L-shaped pipe 9. The water flow drives the movable column 24 to slide upward in the vertical pipe 6 through the buoyancy ball 25 and squeezes the buffer spring 27. The movable column 24 drives the lifting column 19 to move upward. The lifting column 19 drives the rotating column 18 to rotate through the first L-shaped column 22, the second L-shaped column 13, and the spiral groove 17. The rotating column 18 drives the petal 26 to rotate through the rotating shaft 16, so that the water flow is introduced into the connecting pipe 4 and flows into the arc-shaped pipe 5 for buffering. The water is then sprayed out through the second pipe body 7 and the outlet pipe 8. Through the cooperation between the components such as the first pipe body 1, the connecting pipe 4, the L-shaped pipe 9, the arc-shaped pipe 5, and the second pipe body 7, a diversion structure is set up. The diverted water flow drives the petal to rotate, effectively agitating the water flow, reducing water residue, and improving the anti-stagnant water performance.

[0025] At this time, under the action of gravity and the elastic force of the buffer spring 27, the movable column 24 drives the buoyancy ball 25 to move downward. The water flows back to the first pipe body 1 through the L-shaped pipe 9, and is guided into the connecting pipe 4 by the rotation of the flap 26, and flows into the arc-shaped pipe 5 for buffering. It is then sprayed out through the second pipe body 7 and the outlet pipe 8. When the water flows back in the arc-shaped pipe 5, it forms an impact that quickly discharges the water. Through the cooperation between the movable column 24, the buoyancy ball 25, the lifting column 19 and the buffer spring 27, when the flow stops, the elastic force of the buoyancy ball 25 and the return spring 27 is used to realize the return of the diverted water flow, ensuring that the water is fully discharged and optimizing the flow guiding effect.

[0026] By pulling the second L-shaped column 13, the spiral groove 17 drives the rotating column 18 to rotate. The rotating column 18 drives the rotating shaft 16 and the petal 26 to rotate, thus discharging the water. Through the cooperation between the first L-shaped column 22, the limiting ring 21, the annular magnet 20, the second L-shaped column 13, the rotating column 18, and the spiral groove 17, the synchronous design of the petal 26 can be manually driven to rotate, ensuring that the water is completely discharged and further improving the efficiency of preventing water stagnation and guiding the flow.

[0027] The bottom of the inner cavity of the second tube 7 is set with the front higher than the back, which can cooperate with the backflow of the arc-shaped tube 5 to carry the water out and prevent the water from being discharged.

[0028] The circular block 23 is slidably connected inside the vertical pipe 6. A powerful magnet matching the annular magnet 20 is installed on the circular block 23. During the up-and-down movement of the first L-shaped column 22, the limiting ring 21 causes the annular magnet 20 to move up or down on the vertical pipe 6. The annular magnet 20, in conjunction with the powerful magnet, causes the circular block 23 to move up or down inside the vertical pipe 6, pushing the water flow in the arc-shaped pipe 5 out.

[0029] Implementation plan: Connect and circulate water by sealing the device with the faucet or water valve inlet through the sealing ring 2, the first pipe body 1 and the threaded pipe 10; open the faucet or water valve to let the water flow into the first pipe body 1 and then divert it to the vertical pipe 6 through the L-shaped pipe 9.

[0030] The diversion drive rotates the petals. After the water flows into the vertical pipe 6, it pushes the buoyancy ball 25 to drive the movable column 24 to slide upward, squeezing the buffer spring 27. The movable column 24 drives the rotating column 18 to rotate through the lifting column 19, the first L-shaped column 22, the second L-shaped column 13 and the spiral groove 17. The rotating column 18 drives the petals 26 to rotate through the rotating shaft 16, guiding the water flow into the connecting pipe 4. After being buffered by the arc-shaped pipe 5, the water is sprayed out through the second pipe body 7 and the outlet pipe 8.

[0031] When the flow stops, the water flows back. After the faucet or water valve is closed, under the action of gravity and the elastic force of the buffer spring 27, the movable column 24 drives the buoyancy ball 25 to move downward. The water flows back to the first pipe body 1 through the L-shaped pipe 9, and is guided into the connecting pipe 4 by the rotating flap 26. Finally, it is discharged through the arc-shaped pipe 5, the second pipe body 7 and the outlet pipe 8. The backflow of water in the arc-shaped pipe 5 forms an impact, which accelerates the discharge of water.

[0032] Manually assist in drainage by pulling the second L-shaped column 13, which drives the rotating column 18 to rotate through the spiral groove 17; the rotating column 18 drives the rotating shaft 16 and the petals 26 to rotate, thus discharging the remaining water.

[0033] Reset and prevent residue: Through the coordinated action of the first L-shaped column 22, the limiting ring 21, the annular magnet 20, the second L-shaped column 13, the rotating column 18 and the spiral groove 17, the petal 26 is ensured to be completely reset; after drainage is completed, the device automatically returns to the initial state to avoid water residue.

[0034] Example 2 This embodiment provides a stainless steel pipe structure for preventing water stagnation in high-quality drinking water, including: a main pipeline system, a diversion and drive substructure, a sealing and connection substructure, and a protection and limiting substructure.

[0035] The main piping system includes a first pipe body 1, a second pipe body 7, an arc-shaped pipe 5, and an L-shaped pipe 9. The front end of the first pipe body 1 is connected to a faucet or water valve, and the rear end is connected to the second pipe body 7 through a connecting pipe 4. The rear side of the second pipe body 7 is closed, the bottom is connected to a water outlet pipe 8, and the top is connected to the arc-shaped pipe 5. The top of the arc-shaped pipe 5 is connected to a vertical pipe 6, and the top of the vertical pipe 6 is closed. The L-shaped pipe 9 connects the first pipe body 1 and the vertical pipe 6 to form a diversion channel.

[0036] The diversion and drive substructure includes a vertical tube 6, a lifting column 19, and a rotating column 18. The vertical tube 6 is slidably connected to a movable column 24, with a buoyancy ball 25 installed at the bottom and a lifting column 19 passing through the top. The lifting column 19 is fitted with a buffer spring 27, with its bottom end connected to the movable column 24 and its top end extending into the connecting tube 4. The rotating column 18 is matched with the second L-shaped column 13 through a spiral groove 17, driving the rotating shaft 16 and the petals 26 to rotate.

[0037] The sealing and connecting substructure includes a sealing ring 2, which fits against the front side of the first pipe body 1, and the threaded pipe 10 is connected to the faucet via threads; the first pipe body 1 and the second pipe body 7 are connected via a first flange 3, and the connecting pipe 4 is connected to the fastening screw 29 via a second flange 28.

[0038] The protective and limiting substructure includes a first protective tube 12, a second protective tube 14, and a limiting ring 21. The first protective tube 12 is fitted with a sealing tube 15, connected to a connecting tube 4 at the bottom, and has a first movable groove 11 on the right side. The second protective tube 14 is fitted with a vertical tube 6, connected to a second tube body 7 at the bottom, and has a second movable groove 30 on the right side. The limiting ring 21 connects an annular magnet 20 and a first L-shaped column 22 to prevent the rotating column 18 from rotating excessively.

[0039] This invention utilizes a diversion structure to drive the rotation of the water-driven flaps, effectively agitating the water flow and reducing residue. The automatic backflow design ensures that the water is fully discharged, optimizing the flow guidance effect. A manual flap rotation function is also included to ensure complete water discharge.
