Description

Technical Field

[0001] This invention relates to the field of water pollution treatment technology, and in particular to a water purification device based on a mineral filter cartridge. Background Technology

[0002] In existing technologies, water purification devices are widely used in homes, industries, and commercial sectors to improve water quality and ensure water safety. Typical water purification devices usually include multi-stage filtration systems. Their main function is to remove harmful substances such as suspended solids, colloids, organic matter, residual chlorine, heavy metal ions, bacteria, and viruses from raw water through physical interception, chemical adsorption, and selective permeation. During this process, some purification technologies will also remove beneficial minerals such as calcium and magnesium from the water, resulting in reduced mineralization and a bland taste. Therefore, mineral filter cartridges, as functional units in water purification devices, are used to selectively remineralize the purified water. These cartridges usually contain soluble mineral salts or natural mineral materials (such as maifanite, tourmaline, coral sand, magnesium hydroxide, calcium carbonate, etc.). Through slow-release technology, they release trace elements needed by the human body into the water at an appropriate concentration, thereby increasing the mineralization and pH value of the water, improving the taste, and enhancing its drinking value.

[0003] However, after long-term operation of the mineral filter cartridge, the upper part of the filter cartridge is over-consumed and becomes clogged, while the lower part is idle, resulting in an asymmetrical aging problem of "clogging at the top and idle at the bottom". Ultimately, the unused mineral materials in the filter element are discarded prematurely due to the overall performance decline, which not only reduces the material utilization efficiency but also leads to raw material waste and increased replacement costs for users. Summary of the Invention

[0007] Furthermore, the second connecting pipe is a corrugated pipe, and a telescopic sleeve is fixedly connected to the upper side of the second fixing ring. A sliding ring that slides within the adjacent first connecting pipe is fixedly connected to the upper side of the telescopic sleeve.

[0008] Furthermore, a second liquid guiding shell is fixedly connected to the lower side of the first connecting pipe, and a plurality of second fixing pipes are fixedly connected to the lower side of the first connecting pipe. The opposite sides of the plurality of second fixing pipes are all fixedly connected to and communicate with the second liquid guiding shell, and the opposite sides of the plurality of second fixing pipes are all fixedly connected to the second fixing ring and communicate with the inside of the first connecting pipe. The movable frame is fixedly connected to a support frame, and the support frame is fixedly connected to an inlet pipe and an outlet pipe arranged in a linear array. The inlet pipe corresponds one-to-one with the second liquid guiding shell, and the outlet pipe corresponds one-to-one with the first liquid guiding shell.

[0009] Furthermore, both the second liquid guiding shell and the first liquid guiding shell are equipped with one-way valves, and the one-way valves in the two shells have opposite functions.

[0010] Furthermore, one of the bends is provided with a second electric push rod, the telescopic part of the second electric push rod passing through and sealing the adjacent bend, the telescopic part of the second electric push rod being fixedly connected to a sliding member, the sliding member sliding along the bend, the sliding member passing through all the sponges and being fixedly connected to all the sliding rings.

[0011] Furthermore, a perforated plate is fixedly connected to both the first liquid guide shell and the lower bend. A rotating plate is rotatably connected to the lower side of the perforated plate. The rotating plate is used to block the holes of the perforated plate. The rotating plate is provided with a fan-shaped through hole communicating with the holes of the perforated plate.

By rotating the first connecting pipe, the mineral materials in the first fixing ring and the second connecting pipe are naturally distributed due to gravity, thereby achieving the effect of rearranging the mineral materials. The second connecting pipe is continuously stretched and retracted, thereby generating a suction force to draw water into the first fixing ring and the second connecting pipe, thereby achieving the effect of backwashing the mineral materials in them with clean water. The second connecting pipe and the corresponding first fixing ring become elliptical, thereby reducing the internal space and generating radial extrusion force. The radial extrusion force is used to cause the internal mineral materials to migrate and redistribute, thereby achieving dynamic adjustment of the mineral materials in space.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] To address the problem that existing mineral filter cartridges suffer from excessive consumption at the top and idleness at the bottom during prolonged use, resulting in asymmetrical aging and premature disposal of unused mineral materials, thus reducing utilization efficiency, waste, and increased costs, this device proposes a filter cartridge structure that allows the mineral filter cartridge to be flipped over and has sufficient internal space for mineral rearrangement. This increases the utilization rate of mineral materials while extending the life of the filter cartridge. Example 1

[0020] A water purification device based on a mineral filter cartridge, reference Figures 1-6As shown, the device includes a movable frame 1, a control panel 2, a sliding frame 3 slidably connected inside the movable frame 1, a first electric push rod 4 inside the movable frame 1, the telescopic part of the first electric push rod 4 being fixedly connected to the sliding frame 3, a rotating frame 5 rotatably connected to the sliding frame 3, a motor 6 for driving the rotating frame 5 to rotate, a first connecting pipe 7 arranged in a linear array being detachably connected to the rotating frame 5, with adjacent first connecting pipes 7 in contact, a symmetrically distributed curved pipe 8 detachably connected to the rotating frame 5, the symmetrically distributed curved pipes 8 respectively contacting the adjacent sides of adjacent first connecting pipes 7, a symmetrically distributed first fixed pipe 9 fixedly connected inside the movable frame 1, the first fixed pipe 9 being detachably connected to adjacent curved pipes 8, a mineral filter component being provided inside the first connecting pipe 7, the mineral filter component including a first A liquid guiding shell 10 is fixedly connected to the upper side of the first connecting pipe 7. The first liquid guiding shell 10 is detachably connected to the first connecting pipe 7, which is not fixedly connected. A first fixing ring 11 is provided in the first connecting pipe 7, which is fixedly connected to and communicates with the first liquid guiding shell 10. A second connecting pipe 12 located in the first connecting pipe 7 is fixedly connected to and communicates with the lower side of the first fixing ring 11. The first fixing ring 11 is located between the first liquid guiding shell 10 and the second connecting pipe 12. A second fixing ring 13 is fixedly connected to the lower side of the first connecting pipe 7. A sponge 17 is fixedly connected to the second fixing ring 13. The sponge 17 is located between the second fixing ring 13 and the second connecting pipe 12. Mineral material is placed in the first fixing ring 11 and the second connecting pipe 12. The mineral material in the first fixing ring 11 and the second connecting pipe 12 in the first connecting pipe 7 is the same.

[0021] In the above scheme, all electrical components of this device are electrically connected to the control panel 2. In this device, the first connecting pipes 7 are three in a linear array. This number can be adjusted in real time according to the actual situation during actual use. The first electric push rod 4 is used to drive the rotating frame 5 to move horizontally, so that the bent pipe 8 is temporarily disconnected from the corresponding first fixed pipe 9. Through the cooperation of the mineral material and sponge 17 between the first fixed ring 11 and the second connecting pipe 12, multi-stage treatment of water is achieved. When the bent pipe 8 is disconnected from the corresponding first fixed pipe 9, the motor 6 drives all the first connecting pipes 7 to rotate 180° through the rotating frame 5, so that the mineral filter component rotates 180°. During the rotation, the internal space of the first fixed ring 11 and the second connecting pipe 12 increases, giving space to the mineral material and causing the mineral material to be naturally distributed due to gravity, so as to achieve the effect of rearranging the mineral material.

[0022] refer to Figure 6 , Figure 7 , Figure 9 and Figure 10As shown, the second connecting pipe 12 is a corrugated pipe, and a telescopic sleeve 14 is fixedly connected to the upper side of the second fixing ring 13. A sliding ring 16 that slides inside the adjacent first connecting pipe 7 is fixedly connected to the upper side of the telescopic sleeve 14. The sliding ring 16 is fixedly connected to the second connecting pipe 12, and the sliding ring 16 is fixedly connected to the side of the sponge 17 away from the second fixing ring 13. The sponge 17 is located inside the telescopic sleeve 14.

[0023] In the above scheme, the second connecting pipe 12 is initially in an unstretched state, and the telescopic sleeve 14 is used to cover the sponge 17 so that water only passes through the sponge 17 and moves towards the adjacent second fixed ring 13 through the sliding ring 16. While the second connecting pipe 12 is stretched, the sponge 17 is squeezed, thereby increasing the space inside the second connecting pipe 12 and the adjacent second fixed ring 13.

[0024] refer to Figure 2 , Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, a second liquid guiding shell 1301 is fixedly connected to the lower side of the first connecting pipe 7. Several second fixing pipes 1302 are fixedly connected to the lower side of the first connecting pipe 7. The opposite sides of the several second fixing pipes 1302 are fixedly connected to and communicate with the second liquid guiding shell 1301. The opposite sides of the several second fixing pipes 1302 are fixedly connected to the second fixing ring 13 and communicate with the inside of the first connecting pipe 7. The moving frame 1 is fixedly connected to a support frame 18. The support frame 18 is fixedly connected to an inlet pipe 1303 and an outlet pipe 1001 arranged in a linear array. The inlet pipe 1303 corresponds one-to-one with the second liquid guiding shell 1301, and the outlet pipe 1001 corresponds one-to-one with the first liquid guiding shell 10.

[0025] In the above scheme, the support frame 18 is located on the right side of the movable frame 1, the liquid inlet pipe 1303 is located above the adjacent liquid outlet pipe 1001, the liquid inlet pipe 1303 is used to inject water into the corresponding second liquid guide shell 1301, and the liquid outlet pipe 1001 is used to guide the water out of the corresponding first liquid guide shell 10.

[0026] refer to Figure 6 and Figure 10 As shown, both the second liquid guide shell 1301 and the first liquid guide shell 10 are equipped with one-way valves, and the one-way valves in the two shells have opposite functions.

[0027] In the above scheme, when the inlet pipe 1303 delivers water into the second liquid guide shell 1301, the one-way valve in the second liquid guide shell 1301 is in the open state, and the one-way valve in the first liquid guide shell 10 is in the closed state. Conversely, when water flows out from the first liquid guide shell 10, the one-way valve in the first liquid guide shell 10 is in the open state, and the one-way valve in the second liquid guide shell 1301 is in the closed state.

[0028] refer to Figures 3-8As shown, one of the bends 8 is provided with a second electric push rod 20. The telescopic part of the second electric push rod 20 passes through the adjacent bend 8 and is sealed with it. The telescopic part of the second electric push rod 20 is fixedly connected to a sliding member 21. The sliding member 21 slides along the bend 8. The sliding member 21 passes through all the sponges 17 and is fixedly connected to all the sliding rings 16.

[0029] In the above scheme, the lower bend 8 is equipped with a second electric push rod 20, and the sliding member 21 consists of a rod fixedly connected to each other and three connecting plates, which are fixedly connected to the corresponding sliding ring 16.

[0030] refer to Figures 5-7 and Figure 10 As shown, a perforated plate 22 is fixedly connected inside the first liquid guide shell 10 and the lower bend 8. A rotating plate 23 is rotatably connected to the lower side of the perforated plate 22. The rotating plate 23 is used to block the holes of the perforated plate 22. The rotating plate 23 is provided with a fan-shaped through hole communicating with the holes of the perforated plate 22. The sliding member 21 passes through the rotating plate 23. All the bends 8 are rotatably connected to a gear shaft 24. The gear shaft 24 passes through all the sponges 17 and all the perforated plates 22 and is fixedly connected to all the rotating plates 23. A rack frame 25 is fixedly connected to the side of the moving frame 1 near the motor 6. The rack frame 25 is used to drive the gear shaft 24 to rotate.

[0031] In the above scheme, the rotating plate 23 is provided with an arc-shaped guide rail to prevent the rotating plate 23 from having a hard collision with the sliding member 21 when rotating. The perforated plate 22 is a circular plate with multiple fan-shaped holes. The fan-shaped holes on the perforated plate 22 correspond one-to-one with the fan-shaped through holes on the rotating plate 23. When the fan-shaped holes and the fan-shaped through holes are connected, the device is in normal water purification state. When the rotating plate 23 blocks the perforated plate 22, the device is in the state of cleaning each first connecting pipe 7 individually.

[0032] refer to Figure 6 , Figure 7 and Figure 10 As shown, a spring telescopic rod 26 is fixedly connected to the side of the first connecting pipe 7 near the support frame 18. The telescopic part of the spring telescopic rod 26 is hinged to two hinge rods 27. A sealing plate 28 is hinged to the opposite side of each of the two hinge rods 27. One sealing plate 28 is used to seal the adjacent first liquid guiding shell 10, and the other sealing plate 28 is used to seal the adjacent second liquid guiding shell 1301. The support frame 18 is fixedly connected to a linear array of extrusion rods 29. Each extrusion rod 29 corresponds to one of the first connecting pipes 7. The extrusion rods 29 are used to extrude the telescopic part of the corresponding spring telescopic rod 26.

[0033] In the above scheme, the spring telescopic rod 26 is located on the right side of the first connecting pipe 7. When the telescopic part of the spring telescopic rod 26 contacts the corresponding squeezing rod 29, it is squeezed, causing the telescopic part of the spring telescopic rod 26 to retract and pull the corresponding sealing plate 28 through the two hinge rods 27 respectively, so that the two sealing plates 28 slide towards each other and no longer block the right side of the corresponding second liquid guide shell 1301 and the right side of the first liquid guide shell 10.

[0034] Working principle: When water purification is required, the operator connects the inlet pipe to the upper first fixed pipe 9, the outlet pipe to the lower first fixed pipe 9, the liquid inlet pipe 1303 to the inlet pipe, and the liquid outlet pipe 1001 to the wastewater tank. Then, the water to be treated is sent into the upper first fixed pipe 9 through the inlet pipe. The water to be treated passes through the upper bend pipe 8, the perforated plate 22, the fan-shaped through hole of the rotating plate 23, the mineral material between the first fixed ring 11 and the second connecting pipe 12, the sponge 17, and the parts in the subsequent first connecting pipe 7 until it is discharged from the lower bend pipe 8. Finally, it is transported to the outlet pipe through the lower first fixed pipe 9. The water achieves the effect of remineralization in the process of passing through the above parts.

[0035] When the mineral materials need to be rearranged, the operator first pauses the water injection, then extends the telescopic part of the first electric push rod 4 via the control panel 2. During the extension of the first electric push rod 4, the sliding frame 3 drives the rotating frame 5, all the first connecting pipes 7 and their internal parts to move to the right. Simultaneously, the rack frame 25 meshes with the gear shaft 24, causing the gear shaft 24 to drive all the rotating plates 23 on it to rotate. During the rotation of the rotating plates 23, the corresponding perforated plates 22 are blocked. When the gear shaft 24 disengages from the rack frame 25, the rotating plates 23 will... The perforated plate 22 is sealed, making all the first connecting pipes 7 closed. As the two bends 8 move with the rotating frame 5, they disengage from the corresponding first fixed pipes 9. At this time, the telescopic part of the second electric push rod 20 is retracted by the control panel 2, so that the sliding member 21 drives all the sliding rings 16 to slide along the corresponding first connecting pipes 7. During the sliding process, the sliding rings 16 pull the second connecting pipe 12 and squeeze the sponge 17 and the telescopic sleeve 14, so that the sponge 17 and the telescopic sleeve 14 contract and expand the space inside the second connecting pipe 12 and the first fixed ring 11.

[0036] After the space inside the second connecting pipe 12 and the first fixing ring 11 increases, the motor 6 controlled by the control panel 2 drives the rotating frame 5 to rotate 180°. The rotating frame 5 drives the parts on it to rotate 180°. During the rotation of the rotating frame 5 and its parts, the mineral material inside the second connecting pipe 12 and the first fixing ring 11 can move inside them to simulate putting the mineral material into a cup and rotating the cup so that the mineral material is naturally distributed in the cup due to gravity. This achieves the effect of rearranging the mineral material, increasing the utilization rate of the mineral material and extending the life of the filter element.

[0037] After the rotating frame 5 rotates 180°, the rotating frame 5 drives all the first connecting pipes 7 to continue moving. During the process of all the first connecting pipes 7 moving to the right, the telescopic part of the spring telescopic rod 26 gradually contacts the corresponding squeezing rod 29. After the telescopic part of the spring telescopic rod 26 contacts the squeezing rod 29, it retracts. At the same time, the second liquid guide shell 1301 and the first liquid guide shell 10 are respectively connected to the corresponding liquid inlet pipe 1303 and the liquid outlet pipe 1001. During the retraction of the spring telescopic rod 26, the two hinge rods 27 pull the corresponding sealing plates 28 respectively, so that the two sealing plates 28 slide towards each other and no longer block the right side of the corresponding second liquid guide shell 1301 and the right side of the first liquid guide shell 10. This makes the second liquid guide shell 1301 and the first liquid guide shell 10 connected to the corresponding liquid inlet pipe 1303 and the liquid outlet pipe 1001 respectively. At this time, the telescopic part of the first electric push rod 4 no longer extends, and it has now switched to the mode of cleaning each first connecting pipe 7 separately with water.

[0038] When switching to the mode of individually cleaning each first connecting pipe 7 with water, the telescopic part of the second electric push rod 20 extends and then retracts, causing the second connecting pipe 12 to continuously extend and retract, thereby generating a suction force. During the extension process of the second connecting pipe 12, the one-way valve in the second liquid guide shell 1301 is opened, thereby allowing water transported by the water inlet pipe connected to the liquid inlet pipe 1303 to enter the first connecting pipe 7 through the corresponding second fixed pipe 1302 and the corresponding second fixed ring 13. After entering the first connecting pipe 7, the water moves from the sponge 17 towards the first liquid guide shell 10 in the same first connecting pipe 7, so that the water moves from top to bottom. During the flow of water, the mineral materials in the first fixed ring 11 and the second connecting pipe 12 are washed. Conversely, when the second connecting pipe 12 retracts, the one-way valve in the second liquid guide shell 1301 closes and the one-way valve in the first liquid guide shell 10 opens, so that the water that has been cleaned of the mineral materials in the first fixed ring 11 and the second connecting pipe 12 is discharged sequentially from the first liquid guide shell 10 and the outlet pipe 1001 until it is discharged into the wastewater tank connected to the outlet pipe 1001. Through the above working principle, the mineral materials in the first fixed ring 11 and the second connecting pipe 12 are backwashed with clean water.

[0039] After the cleaning of the mineral materials is completed, the telescopic part of the second electric push rod 20 returns to its original position, and all the second connecting pipes 12 and all the sponges 17 return to their initial state. At this time, the telescopic part of the first electric push rod 4 is controlled by the control panel 2, so that the rotating frame 5 drives the parts on it to move to the left to reset. When the second liquid guide shell 1301 is disengaged from the contact with the liquid inlet pipe 1303, the first liquid guide shell 10 is disengaged from the contact with the liquid outlet pipe 1001, and the telescopic part of the spring telescopic rod 26 is disengaged from the contact with the squeezing rod 29, the spring telescopic rod 26 extends and retracts, driving the two adjacent hinge rods 27 to reset. The hinge rods 27 then drive the adjacent sealing plates 28 to reset, so that the two sealing plates 28 resume their blocking of the second liquid guide shell 1301 and the first liquid guide shell 10. Then, the motor 6 is controlled by the control panel 2 to drive the rotating frame 5 to rotate 180° in the opposite direction.

[0040] When the rotating frame 5 and its associated parts move to the left to return to their original position... Figure 3 After reaching the desired state, the bend 8 and the corresponding first fixed pipe 9 are connected, the gear shaft 24 contacts the rack frame 25, causing the gear shaft 24 to drive the three rotating plates 23 to rotate in the opposite direction and reset, so that the fan-shaped through hole on the rotating plate 23 is connected to the hole of the perforated plate 22, so that all the first connecting pipes 7 are released from the closed state, and the water can be purified again. Example 2

[0041] Based on Example 1, and referring to Figure 7 As shown, the diameter of the first fixing ring 11 gradually decreases from one end near the second connecting pipe 12 to the other end, and the first fixing ring 11 is made of a deformable material.

[0042] In Example 1, when the sponge 17 is compressed, but the stretching of the second connecting tube 12 has reached its limit, the control panel 2 controls the telescopic part of the second electric push rod 20 to retract, and the retraction distance is greater than that in Example 1. During the retraction of the telescopic part of the second electric push rod 20, all the sliding rings 16 are moved by the sliding member 21. During the movement of the sliding rings 16, the first fixed ring 11 is deformed, thereby generating radial extrusion force. The radial extrusion force is used to cause the internal mineral material to migrate and redistribute, thereby realizing the dynamic adjustment of the mineral material in space. After this step is completed, the telescopic part of the second electric push rod 20 extends, causing the sliding member 21 to move and reset all the sliding rings 16. At that time, the second connecting tube 12 and the corresponding first fixed ring 11 return to their initial state.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention.
