Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water treatment, in particular to a modular reverse osmosis direct drinking water equipment. BACKGROUND

[0002] In the technical field of water treatment equipment, with the continuous improvement of people's requirements for water quality, the development of direct drinking water equipment has attracted more and more attention. The application of direct drinking water equipment is of great significance to protect the health of residents and improve the quality of life. It can effectively remove impurities, harmful substances and other substances in water, provide safe and clean drinking water for people, and is widely used in many scenes such as families, schools and office places, greatly improving the water conditions of people and promoting the popularization of the concept of healthy drinking water.

[0003] In order to realize the purification and treatment of water, before the emergence of the present technology, there are many kinds of technical means commonly used. The common one is to connect single independent filtering equipment, reverse osmosis equipment and sterilization equipment in sequence to realize multi-stage treatment of water. In the connection of the equipment, the traditional screw connection method is usually used to screw the pipes of each equipment together to ensure the sealing of the connection. Some will also use welding method to firmly connect the pipes of different equipment to ensure smooth water flow. Some will use flange connection to tightly connect the pipes with flange through bolts to realize the communication between the equipment. These connection methods are relatively mature and widely used technical means, which can meet the basic water treatment needs to a certain extent.

[0004] However, the existing connection methods have obvious defects. The traditional screw connection is easy to cause thread wear due to long-term use, resulting in water leakage, and the installation and disassembly process is relatively cumbersome, which is not conducive to the maintenance and replacement of the equipment. Although the welding method is firm, once the welding part fails, it is difficult to repair, and even the entire pipe may need to be replaced. In the case of large water pressure impact on the pipe, the existing connection method is also easy to cause the pipe to fall off, and the disassembly and assembly of each water treatment module are difficult. SUMMARY

[0005] In order to solve the problem of easy falling off under the condition of large water pressure impact on the pipe and difficult disassembly and assembly between each water treatment module, the present application provides a modular reverse osmosis direct drinking water equipment.

[0006] The modular reverse osmosis direct drinking water equipment provided by the present application adopts the following technical scheme:

[0007] The utility model provides a kind of modular reverse osmosis direct drinking water equipment, including raw water tank, multi-medium filtration module, reverse osmosis module, sterilization module connected in turn, high-pressure water pump is arranged between the multi-medium filtration module and reverse osmosis module, the outlet of high-pressure pump is fixed with first pipe, the water inlet of reverse osmosis module is provided with second pipe, second pipe is inserted in the inner cavity of first pipe, quick plug structure is arranged between first pipe and second pipe, unlocking structure for quickly driving first pipe and second pipe to separate is also provided on the outer wall of first pipe, abutting assembly that depends on water flow impact is also provided on second pipe, when water pressure impact is greater, the abutting assembly will first pipe abut tighter.

[0008] By adopting the above technical scheme, raw water first enters the raw water tank, and then is delivered to the multi-medium filtration module by the raw water pump. The sand tank, carbon tank, softening tank, salt tank and precision filter in the module sequentially filter the raw water in multiple stages to remove impurities, particulate matter, odour and hardness in the water. After that, the water filtered initially is pressurized by the high-pressure water pump and delivered to the reverse osmosis module through the first pipe and the second pipe to further remove harmful substances such as dissolved salts and organic matter in the water by using the reverse osmosis membrane. Then, the water enters the sterilization module, is sterilized by ozone in the ozone tower, and then is sterilized by ultraviolet rays in the ultraviolet tank, and finally flows into the external water supply pipeline from the water outlet of the ultraviolet tank to provide safe and clean direct drinking water for users. When installing, only need to insert the second pipe into the inner cavity of the first pipe, the ball of the quick plug structure slides into the second groove on the inner wall of the first pipe under the action of the first elastic member to realize quick connection, and at the same time, the abutting assembly tightly abuts the first pipe under the impact of water flow, and the greater the water pressure, the tighter the abutment, which ensures the stability and reliability of the connection. When disassembling, the knob of the unlocking structure is actuated to move the unlocking ring to force the ball to slide out of the second groove, so that the first pipe and the second pipe can be quickly separated, which is convenient to operate and facilitates the maintenance and replacement of the equipment.

[0009] Optionally, the abutting assembly comprises a guide plate rotating on the inner wall of the second pipe, a top rod sliding along the direction perpendicular to the length of the second pipe, a pressing rod rotationally connected to the outer wall of the second pipe, a pressing block fixed to the end of the pressing rod away from the top rod, the end of the top rod extending into the second pipe abuts against the guide plate, a sealing member is arranged between the guide plate and the inner wall of the second pipe, a compression chamber preventing water flow in the inner cavity of the second pipe from leaking out is formed between the sealing member, the guide plate and the second pipe wall, a torsional spring is arranged on the rotation shaft of the pressing rod, the end of the pressing rod close to the first pipe is bent, and the end of the pressing rod close to the first pipe can be attached to the outer wall of the first pipe, and in the initial state, the top rod abuts against the guide plate under the action of the torsional spring.

[0010] When the water flow enters the second pipe and impacts the flow guide plate, the flow guide plate is rotated by the water flow, and then pushes the top rod abutting against the flow guide plate to slide outward along the direction perpendicular to the length direction of the second pipe. The outward sliding of the top rod drives the pressure rod abutting against the top rod to rotate around the rotation shaft of the pressure rod. Since the rotation shaft of the pressure rod is provided with the torsion spring, the torsion spring makes the top rod abut against the flow guide plate in the initial state. At this time, the rotation of the pressure rod drives the pressing block fixed to the end of the pressure rod away from the top rod to abut against the outer wall of the first pipe. With the increase of the water pressure impact, the rotation range of the flow guide plate is increased, the sliding distance of the top rod is increased, the rotation angle of the pressure rod is increased, and the abutting force of the pressing block against the outer wall of the first pipe is also increased, thereby realizing the effect that the greater the water pressure impact is, the tighter the abutting assembly abuts against the first pipe. Meanwhile, the sealing element arranged between the flow guide plate and the inner wall of the second pipe and the compression cavity formed by the flow guide plate and the second pipe wall can effectively prevent the water flow in the inner cavity of the second pipe from leaking out, thereby ensuring the stability of the impact of the water flow on the flow guide plate and making the abutting process more reliable.

[0011] Optionally, the sealing element is a flexible corrugated plate.

[0012] By adopting the above technical scheme, the flexible corrugated plate is used as the sealing element, which can better adapt to the deformation caused by the rotation of the flow guide plate while meeting the demand of preventing the water flow from leaking out, and the sealing effect is ensured.

[0013] Optionally, a plurality of first anti-falling grooves are formed on the outer wall of the first pipe, and a plurality of second anti-falling grooves are formed on the side wall of the pressing block for cooperating with the first anti-falling grooves.

[0014] By adopting the above technical scheme, the first anti-falling grooves and the second anti-falling grooves are cooperated with each other at the pipe connection position, the friction force is increased, the first pipe and the second pipe are effectively prevented from being separated due to the water pressure impact, the connection stability is enhanced, the risk of water leakage is reduced, and the equipment operation is more reliable.

[0015] Optionally, the quick insertion structure comprises a plurality of first grooves which are spaced apart and arranged on the outer wall of the second pipe, a plurality of rolling balls which slide in the first grooves, and a plurality of first elastic elements which are arranged in the first grooves and drive the rolling balls to reset. A second groove for embedding the rolling ball is formed on the inner wall of the first pipe.

[0016] By adopting the above technical scheme, when the second pipe is inserted into the inner cavity of the first pipe, the rolling ball is extruded by the inner wall of the first pipe, the first elastic element is compressed, and the rolling ball slides into the first groove. When the second pipe is inserted to the appropriate position, the second groove is aligned with the first groove, the first elastic element pushes the rolling ball out and embeds the rolling ball into the second groove, thereby realizing the quick connection of the first pipe and the second pipe. When it is necessary to separate the first pipe and the second pipe, an external force overcomes the elastic force of the first elastic element to make the rolling ball retreat into the first groove, and then the second pipe can be quickly pulled out.

[0017] Optionally, the unlocking structure includes an annular groove formed at the end of the first pipe away from the high-pressure water pump, an unlocking ring sliding in the annular groove, a second elastic element disposed in the annular groove to drive the unlocking ring to reset, a sliding groove formed on the wall of the first pipe in communication with the annular groove, and a lever block sliding in the sliding groove. The annular groove is in communication with the second groove, and the lever block is fixedly connected to the unlocking ring.

[0018] By adopting the above technical solution, the unlocking ring can be slid in the ring groove by moving the toggle block, so that the unlocking ring squeezes the ball and makes it disengage from the second groove, thus quickly separating the first tube from the second tube. The operation is convenient, and the unlocking ring can be automatically reset under the action of the second elastic element.

[0019] Optionally, a sealing ring is embedded on the inner wall of the end of the first pipe away from the high-pressure water pump.

[0020] By adopting the above technical solution, the sealing performance at the connection between the first pipe and the second pipe can be enhanced, preventing water leakage.

[0021] Optionally, the multi-media filtration module includes a sand tank, a carbon tank, a softening tank, a brine tank, and a precision filter connected in sequence. The sand tank is connected to the raw water tank, and a raw water pump is installed between the sand tank and the raw water tank. The outlet of the precision filter is connected to a high-pressure water pump.

[0022] By employing the above technical solutions, the sand tank can filter larger particulate impurities in the water; the carbon tank can adsorb harmful substances such as organic matter and residual chlorine, improving the taste and odor of the water; the softening tank can reduce water hardness and scale formation; the brine tank provides the brine solution needed for the regeneration of the softening tank, maintaining its softening function; and the precision filter further filters out fine impurities, ensuring the quality of the water entering the high-pressure water pump. These components are connected sequentially and work together to perform multi-stage filtration and treatment of raw water, effectively improving water quality and providing a good water quality foundation for subsequent reverse osmosis treatment.

[0023] Optionally, the sterilization module includes an ozone tower and an ultraviolet chamber connected in sequence, with the outlet of the ultraviolet chamber connected to an external water supply pipeline.

[0024] By adopting the above technical solution, the ozone tower utilizes the strong oxidizing properties of ozone to sterilize and disinfect water, removing bacteria, viruses, and other microorganisms. The ultraviolet (UV) chamber uses UV light to destroy the genetic material of microorganisms, further enhancing the sterilization effect. The two are connected sequentially; the ozone tower first performs preliminary sterilization, followed by deep sterilization in the UV chamber, together forming a sterilization module. The outlet of the UV chamber is connected to an external water supply pipeline, allowing the double-sterilized water to be directly supplied to users, providing safe and clean drinking water.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The quick-connect structure can efficiently and quickly connect the first and second pipes. With the unlocking structure, the two pipes can be quickly separated. Compared with the traditional threaded, welded, and flanged connection methods, it creatively solves the problem of cumbersome disassembly and assembly between water treatment modules, and greatly improves the convenience of equipment maintenance and replacement.

[0027] 2. The clamping component can automatically abut against the outer wall of the first pipe by using the impact of water flow, and the greater the water pressure, the stronger the abutment. This feature creatively solves the problem that the pipe is easy to fall off when the water pressure impact is large, and significantly enhances the stability and reliability of the equipment operation.

[0028] 3. Improve the sealing performance of the entire pipeline connection by inserting a ring groove and adding a sealing ring. Attached Figure Description

[0037] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0038] This application discloses a modular reverse osmosis direct drinking water device.

[0039] Reference Figure 1 and Figure 2 The modular reverse osmosis direct drinking water equipment provided in this application includes a raw water tank 1, a multi-media filtration module 2, a reverse osmosis module 3, and a sterilization module 4 connected sequentially via quick-connect fittings. A high-pressure water pump 5 is installed between the multi-media filtration module 2 and the reverse osmosis module 3. When the equipment starts operating, raw water from the raw water tank 1 flows into the multi-media filtration module 2. The high-pressure water pump 5 provides power to transport the water, which has undergone preliminary treatment by the multi-media filtration module 2, to the reverse osmosis module 3. Finally, the water enters the sterilization module 4 for sterilization. This sequential connection and installation of the high-pressure water pump 5 achieves multi-stage treatment of the raw water to obtain direct drinking water. This is because the raw water tank 1 stores the raw water, the multi-media filtration module 2 first performs preliminary filtration to remove larger particles and impurities, the high-pressure water pump 5 provides pressure to force the water into the reverse osmosis module 3 for finer filtration to remove dissolved solids, and finally, the sterilization module 4 sterilizes the water to ensure water quality safety.

[0040] Reference Figure 1 and Figure 2Specifically, the multi-media filtration module 2 includes a sand tank 30, a carbon tank 31, a softening tank 32, a brine tank 33, and a precision filter 34 connected in sequence. The sand tank 30 is connected to the raw water tank 1, and a raw water pump 35 is installed between the sand tank 30 and the raw water tank 1. The outlet of the precision filter 34 is connected to a high-pressure water pump 5. When the raw water pump 35 starts, raw water is transported from the raw water tank 1 to the sand tank 30. The sand tank 30 is usually filled with filter media such as quartz sand. Its body is cylindrical, and the filter media layer is evenly distributed inside. When water flows through the sand tank 30, larger particles of impurities are intercepted, playing a preliminary sedimentation and filtration role. Replaceable features include the use of quartz sand of different particle sizes or other similar filter sands.

[0041] Reference Figure 1 and Figure 2 The raw water pump 35 can be a centrifugal pump, which can generate a certain head and flow rate to transport raw water from the raw water tank 1 to the sand tank 30. Alternative features include using other types of pumps such as screw pumps. After treatment in the sand tank 30, the water flows into the carbon tank 31, which is filled with activated carbon. Activated carbon has a rich porous structure; as the water flows through the carbon tank 31, organic matter and odors in the water are adsorbed. Alternative features include using activated carbon made of different materials such as coconut shell activated carbon or fruit shell activated carbon. The water then enters the softening tank 32, which is used to remove calcium and magnesium ions from the water to prevent scaling. The tank usually contains ion exchange resin, which is granular and has ion exchange function. When water flows through it, calcium and magnesium ions exchange with the ions on the resin, achieving water softening. Alternative features include using different types of ion exchange resin.

[0042] Reference Figure 1 and Figure 2 The brine tank 33 provides the brine required for the regeneration of the softening tank 32, ensuring the continuous operation of the ion exchange resin. Finally, the water passes through the precision filter 34, which typically uses a cartridge filter. The cartridge has a small pore size, further filtering out tiny particles. As water passes through the cartridge, these small impurities are blocked, providing a higher quality water source for subsequent reverse osmosis treatment. The cartridge can be a pleated cartridge, or alternatively, other types such as ceramic cartridges. These components are interconnected, forming a complete multi-media filtration system in which the raw water is gradually purified.

[0043] Reference Figure 1 and Figure 2Specifically, the sterilization module 4 includes an ozone tower 36 and an ultraviolet (UV) chamber 37 connected in sequence. The outlet of the UV chamber 37 is connected to an external water supply pipeline. When water treated by the reverse osmosis module 3 flows into the ozone tower 36, the ozone tower 36 uses the strong oxidizing properties of ozone to sterilize and disinfect the water. The ozone tower 36 is typically a tower-shaped structure, and the ozone generator inside can be a corona discharge ozone generator, which can produce a high concentration of ozone. During the process of water flowing through the ozone tower 36, bacteria and other microorganisms in the water are oxidized and killed by ozone. An alternative feature could be an electrolytic ozone generator. Next, the water enters the UV chamber 37, which is equipped with UV lamps. When the water passes through the UV irradiation area, the UV light emitted by the UV lamps can destroy the DNA structure of bacteria and viruses, achieving secondary sterilization. The UV lamps can be low-pressure mercury lamps, which have a highly efficient sterilization effect. An alternative feature could be a medium-pressure mercury lamp. After undergoing double sterilization, the water is delivered to the external water supply pipeline through the outlet for users.

[0044] Reference Figure 3 and Figure 4 Because the high pressure of the water pump 5 is relatively large, the connection stability of the equipment assembly of the high pressure pump 5 is quite challenging. In order to ensure the stability of the water supply between the high pressure pump 5 and the reverse osmosis module 3, a first pipe 6 is fixed at the outlet of the high pressure pump, and a second pipe 7 is provided at the inlet of the reverse osmosis module 3. The second pipe 7 is inserted into the inner cavity of the first pipe 6, and a quick-connect structure 8 is provided between the first pipe 6 and the second pipe 7.

[0045] Reference Figure 4 and Figure 5 The quick-connect structure 8 includes several first grooves 20 spaced apart on the outer wall of the second tube 7, ball bearings 21 sliding within the first grooves 20, and a first elastic element 22 disposed within the first grooves 20 to drive the ball bearings 21 to return to their original position. A second groove 23 for embedding the ball bearings 21 is provided on the inner wall of the first tube 6. When the second tube 7 is inserted into the first tube 6, the ball bearings 21 are compressed and retract into the first grooves 20. When the second groove 23 aligns with the first groove 20, the first elastic element 22 drives the ball bearings 21 to embed into the second groove 23, achieving a quick connection. The first grooves 20 are circular grooves, evenly spaced along the circumference of the outer wall of the second tube 7. The ball bearings 21 are stainless steel spheres with good wear resistance and smoothness. The first elastic element 22 is a spring, with one end fixedly connected to the ball bearing 21 and the other end fixed to the inner wall of the first groove 20. The first elastic element 22 has a certain elastic coefficient.

[0046] Reference Figure 4 and Figure 5An unlocking structure 9 is provided on the outer wall of the first pipe 6 for quickly disengaging the first pipe 6 from the second pipe 7. The unlocking structure 9 includes an annular groove 24 at the end of the first pipe 6 furthest from the high-pressure water pump 5, an unlocking ring 25 sliding within the annular groove 24, a second elastic element 26 within the annular groove 24 to reposition the unlocking ring 25, a sliding groove 27 on the wall of the first pipe 6 communicating with the annular groove 24, and a lever 28 sliding within the sliding groove 27. The annular groove 24 communicates with a second recess 23, and the lever 28 is fixedly connected to the unlocking ring 25. When it is necessary to separate the first pipe 6 and the second pipe 7, the operator manually slides the lever 28, which moves the unlocking ring 25 within the annular groove 24. The unlocking ring 25 then pushes the ball bearing 21 out of the second recess 23, thereby separating the first pipe 6 and the second pipe 7. The annular groove 24 is an annular groove formed at the end of the first tube 6. Its width and depth can meet the sliding requirements of the unlocking ring 25. Replaceable features include changing the size of the annular groove 24.

[0047] Reference Figure 5 The unlocking ring 25 is a ring structure, fitted inside the ring groove 24, and can slide freely within the ring groove 24. A segmented unlocking ring 25 is also available as a replaceable feature. The second elastic element 26 is also a spring, which allows the unlocking ring 25 to return to its initial position when no external force is applied.

[0048] Reference Figure 4 and Figure 5 The second pipe 7 is also equipped with a clamping component 10 that relies on the impact of water flow to press against the outer wall of the first pipe 6. The greater the water pressure impact, the tighter the clamping component 10 presses against the first pipe 6. When the equipment is installed, the second pipe 7 is inserted into the first pipe 6, and the quick-connect structure 8 quickly completes the connection between the two. When the high-pressure water pump 5 is working and water flows into the second pipe 7 through the first pipe 6, the clamping component 10 enhances the stability of the connection under the impact of water flow. When the equipment needs maintenance or replacement, the unlocking structure 9 can be operated to quickly separate the first pipe 6 and the second pipe 7.

[0049] Reference Figure 5 and Figure 6The clamping assembly 10 includes a guide plate 11 that rotates on the inner wall of the second pipe 7, a push rod 12 that slides along the length direction perpendicular to the second pipe 7, a pressure rod 13 that is rotatably connected to the outer wall of the second pipe 7, and a pressure block 14 fixed to the end of the pressure rod 13 away from the push rod 12. One end of the push rod 12 that extends into the second pipe 7 abuts against the guide plate 11. A sealing element is provided between the guide plate 11 and the inner wall of the second pipe 7. A pressure cavity 15 is formed between the sealing element, the guide plate 11, and the wall of the second pipe 7 to prevent water from leaking out of the inner cavity of the second pipe 7. A torsion spring 16 is provided on the rotating shaft of the pressure rod 13. In the initial state, the push rod 12 abuts against the guide plate 11 under the action of the torsion spring 16. When the water flow impacts the guide plate 11, the guide plate 11 rotates around the connection point with the inner wall of the second pipe 7, thereby pushing the push rod 12 to slide outward along a direction perpendicular to the length of the second pipe 7. The push rod 12 drives the pressure rod 13 to rotate around the pivot, causing the pressure block 14 to press against the outer wall of the first pipe 6. As the water pressure increases, the impact force of the water flow on the guide plate 11 increases, the rotation amplitude of the guide plate 11 increases, the sliding distance of the push rod 12 increases, the rotation angle of the pressure rod 13 increases, and the pressing force of the pressure block 14 against the outer wall of the first pipe 6 also increases accordingly.

[0050] Reference Figure 6 The guide plate 11 is an arc-shaped plate with a smooth surface, which can guide the direction of water flow. The push rod 12 is a cylindrical rod, with one end abutting against the guide plate 11 and the other end contacting the pressure rod 13. It can be replaced by a square rod. In this embodiment, the push rod 12 is set at the end of the guide plate 11 away from the axis of rotation of the guide plate 11, and at this time the push rod 12 is at the position with the largest opening angle with the guide plate 11, so that the water pressure can be sensitively sensed and quickly reacted to achieve the pressing against the outer wall of the first pipe 6.

[0051] Reference Figure 5 and Figure 6 The pressure rod 13 is a rod-shaped structure that is rotatably connected to the outer wall of the second pipe 7 via a pivot. It can rotate around the pivot. In this embodiment, the pressure rod 13 has a bent end. The pressure block 14 is fixed to one end of the pressure rod 13 and is used to abut against the outer wall of the first pipe 6. Several first anti-detachment grooves 18 are provided on the outer wall of the first pipe 6, and several second anti-detachment grooves 19 are provided on the side wall of the pressure block 14 to cooperate with the first anti-detachment grooves 18. When the pressure block 14 abuts against the outer wall of the first pipe 6, the first anti-detachment grooves 18 and the second anti-detachment grooves 19 cooperate with each other, further enhancing the stability of the connection and preventing the first pipe 6 and the second pipe 7 from separating under the impact of high-pressure water flow.

[0052] Reference Figure 5 and Figure 6The sealing element is a flexible corrugated plate 17. This corrugated structure gives it good flexibility and sealing performance, effectively preventing water leakage from the gaps in the inner wall of the second pipe 7. Replaceable features include the use of rubber gaskets. A sealing ring 29 is embedded in the inner wall of the end of the first pipe 6 away from the high-pressure water pump 5. When the first pipe 6 and the second pipe 7 are connected, the sealing ring 29 can prevent water leakage from the connection between the first pipe 6 and the second pipe 7. The sealing ring 29 is usually made of rubber and has good sealing performance. The sealing ring 29 can be made of fluororubber or other materials.

[0053] The implementation principle of this embodiment is as follows: This modular reverse osmosis direct drinking water equipment achieves multi-stage treatment and purification of raw water through a reasonable modular layout and connection structure, ultimately obtaining safe and hygienic direct drinking water. The multi-media filtration module 2 performs preliminary filtration and pretreatment of the raw water, the reverse osmosis module 3 performs fine filtration, and the sterilization module 4 sterilizes and disinfects, ensuring water quality meets standards. The quick-connect structure 8 and unlocking structure 9 facilitate the installation and disassembly of the equipment. The clamping component 10 enhances the stability of the connection under high-pressure water flow. The first anti-loosening texture 18 and the second anti-loosening texture 19 further prevent loosening of the connection, and the sealing ring 29 ensures the sealing of the connection. Compared with traditional direct drinking water equipment and connection methods, this equipment is easier to maintain and replace, can adapt to different usage scenarios, and improves water treatment efficiency and water quality safety.
