Description

Technical Field

[0001] The present invention relates to the technical field of water purification treatment, and particularly relates to a water purification filter element and device with a modification function. Background Art

[0002] A water purification filter element is a key device for water treatment. Its core function is to remove impurities, suspended solids, harmful substances, etc. in water through physical, chemical or biological means, so as to achieve the purification and improvement of water quality. Water purifiers are widely used in places such as family kitchens, office buildings, schools, etc., and can effectively remove impurities in tap water and provide safe and healthy drinking water. In order to improve the beneficial effects of the purified water on the human body, existing water purifiers usually adopt a post-activated carbon filter element containing natural ore to supplement minerals to the purified water.

[0003] However, in the process of using the design of adding minerals to existing water purifiers, the natural ore in the post-activated carbon filter element is released by dissolving in the purified water, making the purified water contain minerals. However, different ores have different dissolution rates in water, resulting in different mineral contents at different positions in the treated water. It is easy to have a situation where the mineral content in the water is too much or too little. This situation will not only lead to uneven distribution of minerals in the water, but also affect the overall stability of water quality. During the use of the filter element, the speed of impurity accumulation on the filter cloth closer to the water inlet of the filter element in the filter element is faster. The part of the filter cloth close to the water inlet will be blocked earlier due to the rapid accumulation of impurities, the resistance of the water flow through these areas increases, resulting in an increase in the pressure difference inside the filter element, shortening the time interval for filter element cleaning or replacement, and increasing the maintenance frequency of the water purifier.

Detailed implementation manners

[0040] The following Figure 1 - attached Figure 9 drawings are used to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0041] Embodiment 1: During the use of existing water purifiers, a post - activated carbon filter element containing natural ore is usually added to supplement minerals to the purified water. Since different ores have different dissolution rates in water, the mineral contents at different positions in the treated water are different, and it is easy to have the situation of too much or too little mineral content in the water. This not only leads to uneven distribution of minerals in the water but also affects the overall stability of the water quality.

[0042] A water purification filter element with a modification function. Please refer to the attached Figure 1 - attached Figure 5 drawings. It includes: a mineralization filter element 4. A first electrode 5 is arranged on the inner wall of the mineralization filter element 4. A hollow tube is arranged at the axis in the mineralization filter element 4. A second electrode 6 is arranged on the outer wall of the hollow tube in the mineralization filter element 4. The first electrode 5 and the second electrode 6 are concentrically arranged. An ion membrane 7 and a diversion plate 13 are arranged between the first electrode 5 and the second electrode 6. Both the ion membrane 7 and the diversion plate 13 are wound circumferentially around the periphery of the second electrode 6. The ion membrane 7 and the diversion plate 13 are connected. The ion membrane 7 is used to adsorb minerals. A mineralizer 14 is arranged between the ion membranes 7. The diversion plate 13 is located in the middle of the ion membranes 7. The ion membrane 7 and the diversion plate 13 are jointly arranged in a spiral pattern, and the gap width between the ion membrane 7 and the diversion plate 13 remains the same along the circumferential direction.

[0043] In the above solution, it aims to solve the problem that when adding minerals to the filtered water in a water purifier, the dissolution rates of different natural ores in water are different, and the mineral content in the purified water will change continuously, affecting the uniformity of the mineral content in the water and the beneficial effects of the water quality on the human body; the second electrode 6 is located inside the first electrode 5, and both the first electrode 5 and the second electrode 6 are spiral. The internal water flow first passes through the mineralizer 14, so that a large amount of minerals are mixed in the water. Then, the water flow passes through the spiral guiding of the ion membrane 7 and the flow guiding plate 13, and the water mixed with minerals is discharged from the hollow tube inside the mineralization filter element 4. The first electrode 5 and the second electrode 6 are externally connected to a DC power supply (an existing device, not shown in the figure). The positive and negative poles connected to the first electrode 5 and the second electrode 6 can be freely switched. The materials of the first electrode 5 and the second electrode 6 are titanium alloy, which has good corrosion resistance and is not prone to oxidation and delamination when electrified in water. A mineral monitoring device (an existing mechanism, not shown in the figure) is provided at the water outlet of the mineralization filter element 4 to detect the mineral content in the water treated by this device, so as to facilitate the real-time regulation of this device (that is, switch the positive and negative poles of the DC power supply connected to the first electrode 5 and the second electrode 6).

[0044] Working process: When using this filter element to add minerals to the filtered water, the filtered water is injected into the mineralization filter element 4. The filtered water is discharged from the hollow tube inside the mineralization filter element 4 after being guided by the ion membrane 7 and the flow guiding plate 13 inside the mineralization filter element 4. Before the filtered water is guided by the ion membrane 7, the filtered water flow first passes through the mineralizer 14, and the natural minerals in the mineralizer 14 dissolve into the water. The water passing through the mineralizer 14 is distributed with minerals. Before starting to inject water into the mineralization filter element 4, the first electrode 5 and the second electrode 6 are electrified through the DC power supply, and an electric field is generated between the first electrode 5 and the second electrode 6. By controlling the switching of the connection state between the positive and negative poles of the DC power supply and the first electrode 5 and the second electrode 6, the moving direction of the mineral ions in the water is controlled by the electric field. For example, the mineral ions on the ion membrane 7 are released through the electric field to increase the mineral content in the water, or the mineral ions in the water are adsorbed on the ion membrane 7 through the electric field to reduce the mineral content in the water. Combining the detection of the mineral content in the water treated by this device by the mineral monitoring device, the mineral content in the water treated by this device is kept stable, ensuring the stability of the water quality. When the water flow stops being injected, the DC power supply is automatically powered off to avoid the no-load operation of the electrodes.

[0045] Embodiment 2: On the basis of Embodiment 1, this water purification device applies the above-mentioned water purification filter element with a modification function. Please refer to Appendix Figure 1 Appendix Figure 2 Appendix Figure 6 Appendix Figure 7As shown in the figure, the water purification device includes: a protective shell 1, a mineralization filter element 4 is installed in the protective shell 1, a first filter element 2 and a second filter element 3 are installed in the protective shell 1, the first filter element 2, the second filter element 3 and the mineralization filter element 4 are connected in series in sequence through pipelines, a liquid storage cavity 8 and two diversion channels 9 are arranged at the lower part of the first filter element 2 and are communicated with each other, the liquid storage cavity 8 is communicated with the first filter element 2, the two diversion channels 9 are commonly communicated with a three-way pipe 10, a partition plate 11 is slidably connected at the communication hole between the liquid storage cavity 8 and the first filter element 2, a rotating sleeve 12 is rotatably connected in the first filter element 2, and a plurality of fan plates and a plurality of stirring rods are arranged on the rotating sleeve 12; a flow rate control mechanism is arranged in the liquid storage cavity 8 and is used for moving the partition plate 11 to change the flow rate of the water entering the first filter element 2; a buffer mechanism is arranged in the liquid storage cavity 8 and is used for alleviating the impact of the water flow on the structure in the first filter element 2. All the stirring rods on the rotating sleeve 12 are spiral. The flow rate control mechanism includes: a support plate 21 fixedly connected in the liquid storage cavity 8, a sliding rod 22 is slidably connected on the support plate 21, and the sliding rod 22 is opposite to one of the diversion channels 9; a connecting plate 23 is connected to the partition plate 11 in a limited sliding manner, a first spring is fixedly connected between the connecting plate 23 and the liquid storage cavity 8, a first tension spring is fixedly connected between the partition plate 11 and the connecting plate 23, a fixing plate 24 is arranged on the connecting plate 23, the sliding rod 22 is used for extruding the fixing plate 24, the fixing plate 24 is in an inclined state, a round roller is arranged at the end of the sliding rod 22 close to the fixing plate 24, and the sliding rod 22 extrudes the fixing plate 24 through the round roller.

[0046] In the above solution, it aims to solve the problem that for the housing in the community, the water output of the household water pipe changes continuously at different times. Especially during the peak water consumption period, the flow rate of the household water pipe will decrease significantly, resulting in too low water flow rate into the water purifier filter element. When the water enters the first filter element 2, it will impact the fan plate on the rotating sleeve 12 and cause the rotating sleeve 12 to rotate. The rotating sleeve 12 drives the stirring rod on it to rotate, generating turbulence in the first filter element 2 to ensure the uniformity of the filtering effect at different positions of the filter cloth, and reducing the shortening of the replacement interval of the filter element due to excessive blockage at some positions of the filter cloth in the first filter element 2; Initially, the connecting plate 23 is in the lower limit state of the partition plate 11 (that is, if the connecting plate 23 moves downward, the connecting plate 23 can directly drive the partition plate 11 to move synchronously). In daily life, the normal water flow rate in the water pipe is set as the high flow rate state, while during the peak water consumption period, the water slowly flowing out of the water pipe is the low flow rate state. The first filter element 2 is provided with multiple layers of filter cloth and activated carbon rods. The multiple layers of filter cloth and activated carbon rods in the first filter element 2 are used to remove suspended solids and small particles in the water. The second filter element 3 is used to filter out impurities such as heavy metals in the water. The first filter element 2, the second filter element 3, and the mineralization filter element 4 are placed in sequence from left to right and connected in series in the protective shell 1, so that the water injected into the device is processed by the first filter element 2, the second filter element 3, and the mineralization filter element 4 in sequence. The unprocessed water enters the first filter element 2 through the three-way pipe 10, the diversion channel 9, and the liquid storage cavity 8 in sequence. The water filtered by the first filter element 2 is injected into the second filter element 3 for secondary filtration, and finally the water processed by the mineralization filter element 4 is discharged from the right side of the device.

[0047] A control panel is provided on the protective shell 1. The mineral monitoring device is electrically connected to the control panel. The control panel controls the switching of the connection between the first electrode 5 and the second electrode 6 and the positive and negative poles of the DC power supply. The two diversion channels 9 are distributed vertically. The water entering the first filter element 2 is injected into the second filter element 3 after passing through the filtration of multiple layers of filter cloth and activated carbon rods in sequence. Initially, the partition plate 11 blocks the largest area of the communication hole between the liquid storage cavity 8 and the first filter element 2. A damping is provided between the support plate 21 and the sliding rod 22 to slow down the reciprocating movement speed of the sliding rod 22 and reduce its influence by the change of water flow rate. The fixing plate 24 is inclined from top to bottom to the right.

[0048] Workflow: When the user starts to draw the water processed by this device, this device starts. The water to be processed is injected into the first filter element 2 through the three-way pipe 10, the diversion channel 9, and the liquid storage cavity 8, and is discharged from the right side of this device after being processed by the second filter element 3 and the mineralization filter element 4. The filtered water is drawn by the user. If the water flow rate in the three-way pipe 10 is low, the three-way pipe 10 injects water into the two diversion channels 9. The lower diversion channel 9 is blocked by the buffer mechanism. Most of the water in the three-way pipe 10 is injected into the liquid storage cavity 8 through the upper diversion channel 9. The remaining water in the three-way pipe 10 enters the liquid storage cavity 8 through the gap between the lower diversion channel 9 and the buffer mechanism. The water flow pushes the sliding rod 22 to move to the right, and the upper diversion channel 9 is opened. The round roller at the end of the sliding rod 22 squeezes the fixed plate 24, pushing the fixed plate 24 to drive the connecting plate 23 to move upward. The connecting plate 23 drives the partition plate 11 to move upward through the first tension spring connected to the partition plate 11. The connecting plate 23 compresses the first spring connected to it. The area of the communication hole between the liquid storage cavity 8 and the first filter element 2 blocked by the partition plate 11 decreases, and the flow area of the communication hole between the liquid storage cavity 8 and the first filter element 2 increases (if the water flow rate in the three-way pipe 10 is larger, the farther the sliding rod 22 is pushed to the right, the larger the flow area of the communication hole between the liquid storage cavity 8 and the first filter element 2). Thus, the flow area of the communication hole between the liquid storage cavity 8 and the first filter element 2 is adaptively adjusted according to the water flow rate injected into this device, so that the water injected into the first filter element 2 maintains a stable state with a high flow rate. The rotating sleeve 12 in the first filter element 2 keeps stable rotation, making the water flow in the first filter element 2 maintain a turbulent state, ensuring the uniformity of the filtering effect at different positions of the filter cloth in the first filter element 2, and reducing the possibility of excessive blockage at a certain position of the filter cloth in the first filter element 2).

[0049] When the user has taken in enough water, the user stops taking in water, and the three-way pipe 10 stops injecting water. The connecting plate 23 moves downward and resets under the elastic force of the first spring connected thereto. The connecting plate 23 squeezes the sliding rod 22 through the fixed plate 24, so that the sliding rod 22 moves and resets. The connecting plate 23 drives the partition plate 11 to move and reset synchronously. At this point, all parts in the device are restored to their initial positions. If the water flow rate injected into the two diversion channels 9 by the three-way pipe 10 is large at the beginning (i.e., high flow state), the water flow passes through the sliding rod 22 to move the partition plate 11 upward. At the same time, the water flow causes the buffer mechanism to actively control the partition plate 11 to restore its initial position, and the partition plate 11 stretches the first tension spring connected thereto. The buffer mechanism alleviates the impact of high-flow water instantly entering the liquid storage chamber 8 (similar to the flow change caused by the rapid increase in water flow at the water outlet of the pipeline when the valve is opened, that is, the "water hammer" phenomenon). The partition plate 11 quickly blocks the connecting hole between the liquid storage chamber 8 and the first filter element 2, temporarily weakening the impact of high-flow water on the filtration point in the first filter element 2. Subsequently, the partition plate 11 gradually moves upward and resets under the tension of the first tension spring connected to it, and the high-flow water in the three-way pipe 10 is injected into the first filter element 2 through the two guide channels 9 and the liquid storage chamber 8. When the user stops receiving water, the partition plate 11 moves and resets, and the buffer mechanism resets. At this point, all parts in the device return to their initial positions.

[0050] Please refer to the attached Figure 6 -Attached Figure 9 As shown, the buffer mechanism includes: a sliding block 31, which is sealingly and slidably connected in the liquid storage chamber 8, a buffer airbag 32 is arranged between the sliding block 31 and the liquid storage chamber 8, and the buffer airbag 32 is filled with gas; an active reset component, which is arranged in the liquid storage chamber 8, and is used to actively control the partition plate 11 to block the connecting hole between the liquid storage chamber 8 and the first filter element 2 according to the flow rate of the water flow in the three-way pipe 10, and the active reset component includes: a fixed frame 41, which is fixed in the liquid storage chamber 8, and the fixed frame 41 is slidably connected with a blocking block 42, and a second spring is fixed between the blocking block 42 and the fixed frame 41, and the blocking block 42 is opposite to another guide channel 9, blocking A cavity is provided on one side of the block 42 close to the partition plate 11, and a sliding column 43 is sealingly and slidably connected in the cavity of the blocking block 42. A through hole communicating with the inner cavity is provided on the blocking block 42, and a third spring is fixedly connected between the sliding column 43 and the blocking block 42. A fixed block 44 is provided on the partition plate 11, and an inclined surface is provided on the fixed block 44. The sliding column 43 is used to squeeze the inclined surface of the fixed block 44. A limiting pin 51 is slidably connected to the fixing frame 41, and a fourth spring is fixedly connected between the limiting pin 51 and the fixing frame 41. A blind hole is provided on the blocking block 42, and the limiting pin 51 limits the movement of the blocking block 42 through the blind hole on the blocking block 42.

[0051] In the above solution, it is aimed that if the initial water flow rate in the three-way pipe 10 is a high flow rate, the partition plate 11 is actively controlled to move back to its original position, reducing the communication area between the liquid storage chamber 8 and the communication hole of the first filter element 2, and weakening the impact of the high-flow water on the filtering part in the first filter element 2; initially, the limit pin 51 limits and blocks the blocking block 42, and the blocking block 42 cannot move. When the high-flow water impacts the blocking block 42, the blocking block 42 moves and the limit pin 51 releases the limit on the blocking block 42 at the same time. The cross-sectional area of the through hole on the blocking block 42 is smaller than the cross-sectional area of the sliding column 43. When the sliding column 43 squeezes the fixed block 44, the water in the cavity of the blocking block 42 is slowly discharged through its through hole, so that the sliding column 43 slowly contracts into the cavity of the blocking block 42. The elastic coefficient of the first spring connected to the partition plate 11 is greater than the elastic coefficient of the third spring connected to the sliding column 43. When the first spring drives the partition plate 11 to move, the partition plate 11 can compress the third spring connected to the sliding column 43 through the fixed block 44. When the high-flow water impacts the sliding block 31, the sliding block 31 squeezes the buffer airbag 32, and the buffer airbag 32 absorbs energy by compressing the gas inside it, slowing down the moving speed of the sliding block 31, thereby weakening the change in the flow rate in the liquid storage chamber 8. The inclined surface of the fixed block 44 is inclined from top to bottom and to the left. The blind hole on the blocking block 42 is hemispherical. One side of the limit pin 51 close to the blocking block 42 is hemispherical. The limit pin 51 is limited by inserting only the hemispherical part into the blind hole of the blocking block 42. The depth of the blind hole on the blocking block 42 is less than the radius of the hemispherical part of the limit pin 51.

[0052] Working process: when high-flow water is injected into the two diversion channels 9 through the three-way pipe 10, the high-flow water pushes the sliding rod 22 to move to the right, and the sliding rod 22 moves the partition plate 11 upward through the connecting plate 23 and the fixed plate 24. At the same time, the high-flow water pushes the blocking block 42 to move to the right, and the blind hole of the blocking block 42 squeezes the limit pin 51 to move upward, and the limit pin 51 compresses the fourth spring connected to it, and the limit of the blocking block 42 is released. As the blocking block 42 moves to the right, the blocking block 42 compresses the second spring connected to it, and the blocking block 42 squeezes the inclined surface of the fixed block 44 through the sliding column 43. The fixed block 44 drives the partition plate 11 to move downward and reset, and the partition plate 11 stretches the first tension spring connected to it, and the partition plate 11 returns to its initial position. The blocking area of ​​the connecting hole between the liquid storage chamber 8 and the first filter element 2 is the largest, and then the partition plate 11 is in contact with The fixed block 44 is driven upward by the tension of the first tension spring connected to it, and the inclined surface of the fixed block 44 gradually moves the sliding column 43 into the cavity of the blocking block 42, and the water in the cavity of the blocking block 42 is discharged through its through hole. The sliding column 43 compresses the third spring connected to it, and the relative position of the connecting plate 23 and the partition plate 11 is restored. When the sliding column 43 loses contact with the fixed block 44, the sliding column 43 gradually restores its initial state with the blocking block 42 under the elastic force of the third spring connected to it, and the water in the liquid storage chamber 8 is replenished into the cavity of the blocking block 42 through the small through hole. At the moment when high-flow water enters the liquid storage chamber 8, the water flow in the liquid storage chamber 8 increases, the sliding block 31 moves downward and compresses the buffer airbag 32, thereby weakening the water pressure fluctuation in the liquid storage chamber 8, and finally the water in the liquid storage chamber 8 is injected into the first filter element 2 for filtration.

[0053] When the water flow in the liquid storage chamber 8 is stable, the buffer airbag 32 expands and pushes the sliding block 31 to move and reset. When the user stops collecting water, the three-way pipe 10 stops injecting water, and the blocking block 42 moves and resets under the elastic force of the second spring connected to it. The limit pin 51 moves downward and resets under the elastic force of the fourth spring connected to it. The limit pin 51 is reinserted into the blind hole of the blocking block 42, and the blocking block 42 returns to its initial limit state. The connecting plate 23, the sliding rod 22 and the partition plate 11 all move and reset. At this point, all parts in the device return to their initial positions.

[0054] Example 3: Based on Example 2, please refer to the attached Figure 7 -Attached Figure 9 As shown, it also includes: a blocking mechanism, which is arranged in the guide channel 9 on the upper side and is used to block the guide channel 9 on the upper side. The blocking mechanism includes: a fixed frame 61, which is fixedly connected to the guide channel 9 on the side close to the sliding rod 22. The fixed frame 61 is slidably connected with a sliding baffle 62. A second tension spring is fixedly connected between the sliding baffle 62 and the fixed frame 61. Strip holes are provided on the fixed frame 61 and the sliding baffle 62. The positions of the strip holes on the fixed frame 61 and the sliding baffle 62 are complementary.

[0055] In the above solution, when the water flow rate in the tee 10 changes significantly, it aims to improve the judgment of the water flow change limit by the plugging block 42, facilitating the timely reset of the partition plate 11 and restoring the maximum occlusion state of the communication hole between the liquid storage cavity 8 and the first filter element 2; when the fixed frame 61 and the sliding baffle 62 are in contact, the strip holes of the fixed frame 61 and the sliding baffle 62 are both blocked, forming a seamless closed surface to completely block the water flow, so as to temporarily block the upper diversion channel 9 and ensure that the plugging block 42 quickly releases the occlusion state of the lower diversion channel 9, facilitating the quick response of the sliding block 31 to the flow rate in the liquid storage cavity 8.

[0056] Working process: When the water flow rate changes significantly instantaneously, when the water flows through the tee 10 and injects into the two diversion channels 9, the water flow in the upper diversion channel 9 passes through the strip hole of the sliding baffle 62 and pushes it to move to the right. The second tension spring between the fixed frame 61 and the sliding baffle 62 is stretched, and the fixed frame 61 and the sliding baffle 62 are in contact with each other. The strip holes on the fixed frame 61 and the sliding baffle 62 are both blocked, and the upper diversion channel 9 is temporarily blocked. All the water in the tee 10 enters the lower diversion channel 9. The water flow pushes the plugging block 42 to move to the right. The plugging block 42 squeezes the inclined surface of the fixed block 44 through the sliding column 43. If the user just uses this device to receive water, the high-flow water is injected into the two diversion channels 9 through the tee 10 (which means the water flow rate in the diversion channels 9 increases from zero). At this time, the partition plate 11 is in the initial position, and the sliding column 43 only touches the inclined surface of the fixed block 44 (the partition plate 11 is in the initial position and does not move). If the water flow rate in the tee 10 suddenly changes from low to high during the use of this device (previously, the low-flow water impacts the sliding rod 22 through the upper diversion channel 9, and the partition plate 11 is driven upward by the first tension spring and the connecting plate 23 connected to it), the fixed frame 61 and the sliding baffle 62 also come into contact with each other and block the upper diversion channel 9. At this time, the sliding column 43 moves and squeezes the inclined surface of the fixed block 44, and the fixed block 44 drives the partition plate 11 to move downward to restore the initial position, reducing the impact of the water flow rate change on the filtering part in the first filter element 2 and ensuring the safety of the parts in this device.

[0057] After the flow rate of water in the above two three-way pipes 10 changes, the sliding column 43 slowly releases the extrusion on the fixed block 44. At the same time, the sliding baffle 62 moves back to its original position under the pulling force of the second tension spring connected to it, and the upper diversion channel 9 resumes the connected state. A part of the water in the three-way pipe 10 flows through the strip-shaped holes of the fixed frame 61 and the sliding baffle 62. Another part of the water in the three-way pipe 10 flows into the liquid storage cavity 8 through the lower diversion channel 9. The water flow in the upper diversion channel 9 makes the connecting plate 23 move upward through the sliding rod 22 and the fixed plate 24, and the first tension spring connected to the partition plate 11 is stretched. As the sliding column 43 slowly releases the extrusion on the fixed block 44, the partition plate 11 moves upward under the pulling force of the first tension spring connected to it, and finally the communication area between the liquid storage cavity 8 and the communication hole of the first filter element 2 becomes the largest.
