Description

Technical Field

[0001] The present invention relates to the technical field of water purification systems, and in particular to a water purification system with a water hardness adjustment function. Background Art

[0002] Water is humanity's most precious resource. In many areas of my country, water hardness is excessively high, causing significant inconvenience to industrial and agricultural production and people's daily lives. Water hardness refers to the calcium and magnesium ion content in water. Water softening is the treatment of these ions. Ion exchange softening is currently the most widely used water softening process, specifically reducing water hardness. Softening water treatment technology consists of three parts: the ion exchange vessel, the addition of a regenerant, and the forward and backwash processes. The basic principle of softening is ion exchange. The main element of the exchange is the ion exchange resin, which displaces Ca2+ and Mg2+ from the water. Therefore, cation exchange resin is generally used. As the amount of Ca2+ and Mg2+ increases within the resin, its efficiency in removing Ca2+ and Mg2+ decreases. Therefore, after a period of use, softening water treatment equipment is typically regenerated with sodium chloride to restore its efficiency and extend its service life.

[0003] The existing water purification system has certain drawbacks when in use. First, the existing water purification system does not have a good graded adjustment function when adjusting the hardness of water quality, and cannot adjust the hardness of water quality by simply adjusting the water flow size. Secondly, the diversion device of the existing water purification system does not have good sealing when adjusted, and cannot achieve accurate diversion of water volume. Finally, during the use of the existing water purification system, the water near the water port is not provided with a similar one-way valve component, and thus there will be a water leakage problem during the replacement and installation process of the filter component. For this reason, a water purification system with water hardness adjustment function is proposed. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention can solve the problem that the existing water purification system does not have a good graded adjustment function when adjusting the softness and hardness of water quality by setting the first diversion hole, the second diversion hole and the third diversion hole. The problem that the softness and hardness of water quality cannot be adjusted by simply adjusting the water flow size is that the internal thread on the diversion shell and the external thread on the movable part are threadedly connected. The movable part will gradually move upward after rotation. The two mounting rings installed on the movable part and the first sealing ring installed in the first mounting groove opened on the two mounting rings will also move upward with the movable part. When the first sealing ring on the lower side of the two first sealing rings on the movable part moves between the opening positions of the first diversion hole and the second diversion hole, the water to be filtered is diverted through the first diversion hole and flows into the diversion shell with a smaller flow rate. , which can achieve a certain degree of water hardness adjustment. When the first sealing ring on the lower side of the two first sealing rings on the movable part moves to between the opening positions of the second diverter hole and the third diverter hole, the water to be filtered will enter the interior of the diverter shell through the first diverter hole and the second diverter hole, so that the water flow entering the interior of the diverter shell increases, and the water hardness can be adjusted to a greater extent. When the first sealing ring on the lower side of the two first sealing rings on the movable part moves to the upper side of the opening position of the third diverter hole, the water to be filtered will enter the interior of the diverter shell through the first diverter hole, the second diverter hole and the third diverter hole, so that the water flow entering the interior of the diverter shell is the largest, which can adjust the water hardness to the maximum extent, and can enable the device to achieve the function of graded adjustment of water hardness.

[0017] 2. By setting the two first sealing rings and the second sealing ring, the problem of the existing water purification system's diversion device not having good sealing performance during adjustment can be solved, and the accurate diversion of water volume cannot be achieved. The existing water purification system's diversion device does not have a clamped sealing component, which will cause the water to be filtered to pass through the gaps between the components and pass through each component, which will cause the adjustment results of the water quality hardness to fluctuate greatly. The upper first sealing ring among the two first sealing rings can prevent the water to be filtered from flowing out of the device through the gap between the diversion shell and the movable part. The lower first sealing ring among the two first sealing rings can prevent excess water to be filtered from entering the interior of the diversion shell, avoiding the large fluctuation of the adjustment results of the water quality hardness. The second sealing ring can prevent the water to be filtered inside the diversion shell from directly passing through the gap between the movable part and the connecting part and entering the interior of the movable part and the connecting part. The two first sealing rings and the second sealing ring can achieve accurate diversion of water volume in this device.

[0018] 3. The internal thread, external thread, first diversion hole, second diversion hole and third diversion hole of this device can facilitate the user to achieve the function of adjusting the water hardness in four grades by simply rotating the movable parts;

[0019] If the lower first sealing ring of the two first sealing rings is located below the first diversion hole 3, all the water to be filtered in this process will be filtered and softened before flowing out of the device, which is the maximum filtering and softening state of the device.

[0020] If the lower first sealing ring of the two first sealing rings moves between the opening positions of the first diversion hole and the second diversion hole, the water to be filtered passes through the filter material and then enters the interior of the bottom cover through the plurality of second filter holes opened on the lower filter plate. Then, it enters the interior of the connecting nozzle through the plurality of connecting holes opened on the connecting nozzle. Then, the water simply filtered by the filter material is mixed with the filtered and softened water, which can reduce the degree of softening of the water of the device to a certain extent, thereby achieving the purpose of regulating the softened water.

[0021] If the lower first sealing ring of the two first sealing rings is moved between the opening positions of the second diversion hole and the third diversion hole, the water to be filtered will enter the interior of the diversion shell through the first diversion hole and the second diversion hole, so that the water flow entering the diversion shell is increased, and more water that has been simply filtered by the filter material is mixed with the filtered and softened water, which can greatly reduce the degree of water softening of the device;

[0022] If the first sealing ring on the lower side of the two first sealing rings is moved to the upper side of the opening position of the third diversion hole, the water to be filtered will enter the interior of the diversion shell through the first diversion hole, the second diversion hole and the third diversion hole, so that the water flow entering the interior of the diversion shell is maximized, and then the water that is simply filtered by the filter material is mixed with the filtered and softened water at most, which can reduce the degree of water softening of this device to the greatest extent.

[0023] 4. The one-way groove and one-way piston are provided, which can solve the problem that there is no one-way valve component near the water outlet during use, and then there is water leakage during the replacement and installation process of the filter component. The elastic action of the provided piston spring pushes the one-way piston, which can make the third sealing ring sleeved on the one-way piston disengage from the funnel-shaped inner wall of the abutting one-way groove, and then after the water in the water inlet flows into the one-way groove, it prevents the water from leaking from the one-way groove to the connecting groove. During the installation of the filter component, the user inserts the upper part of the housing of the filter component into the inside of the abutting groove and the connecting groove, and then the upper part of the housing is The sixth sealing ring and the fourth sealing ring on the diverter shell can respectively abut the inner walls of the connecting groove and the communicating groove, and then the upper side of the outer shell will abut one end of the one-way piston and drive the one-way piston to move toward the position of the packaging cover. At the same time, after the one-way piston is driven by the outer shell, the third sealing ring sleeved on the one-way piston will break away from the funnel-shaped inner wall of the abutting one-way groove, and then the water to be treated will enter the connecting groove from the one-way groove. The sixth sealing ring can prevent the water to be treated from leaking out of the connecting groove, and the fourth sealing ring can prevent the water to be treated from leaking from the connecting groove to the inside of the communicating groove.

When in use, first, the water inlet 32 ​​and the water outlet 33 on the device are connected to the water inlet pipe and the water outlet pipe respectively. When the water to be treated in the water inlet pipe enters the water inlet 32, it first enters the one-way groove 34. Due to the elastic action of the piston spring 41, the third sealing ring 44 sleeved on the one-way piston 39 can be pushed to abut against the funnel-shaped inner wall of the one-way groove 34, thereby preventing the water to be treated from entering the connecting groove 36. This can prevent water from leaking out of the cover 31 when the filter component is not installed.

[0052] The next step is to install the filter component. The user needs to insert the upper part of the shell 1 of the filter component into the inside of the abutment groove 35 and the connecting groove 36. At the same time, the two clamping plates 48 installed on the upper part of the shell 1 need to be inserted into the inside of the clamping groove 47 from one end of the two clamping grooves 47. As the filter component continues to be inserted, the upper part of the shell 1 will be inserted into the inside of the connecting groove 36. The sixth sealing ring 60 on the upper part of the shell 1 and the fourth sealing ring 45 on the diverter shell 2 can respectively abut against the inner walls of the connecting groove 36 and the connecting groove 37. Then the upper side of the shell 1 will abut against one end of the one-way piston 39 and drive the one-way piston 39 to move toward the position of the packaging cover 40. Wait until the two clamping plates 48 abut against the two At the inner bottom of each clamping groove 47, the user needs to rotate the filter component so that the two clamping plates 48 are driven to the other end of the two clamping grooves 47. The two clamping grooves 47 abut against the inner sides of the two clamping plates 48, which can prevent the cover body 31 from being disconnected from the filter component. At the same time, after the one-way piston 39 is driven by the shell 1, the third sealing ring 44 sleeved on the one-way piston 39 will be separated from the funnel-shaped inner wall of the abutting one-way groove 34, and then the water to be treated will enter the connecting groove 36 from the one-way groove 34. The sixth sealing ring 60 can prevent the water to be treated from leaking out of the connecting groove 36. The fourth sealing ring 45 can prevent the water to be treated from leaking from the connecting groove 36 to the inside of the communicating groove 37.

[0053] Next, the water to be filtered will enter the interior of the outer shell 1 through the gaps between the ribs 7. Since there is a certain gap between the outer shell 1 and the diversion shell 2, the water to be filtered can flow from the gap between the outer shell 1 and the diversion shell 2 to the interior of the bottom shell 27. The water to be treated enters the interior of the bottom shell 27 through the third filter holes provided on the third filter plate 28, and is then filtered by the softening material inside the bottom shell 27. The softened water then enters the bottom of the bottom shell 27 through the second filter holes provided on the fourth filter plate 29. The support frame 30 is provided to isolate a movable space from the bottom of the bottom shell 27. The filtered and softened water flows into the interior of the connecting pipe 6 through the bottom space of the bottom shell 27, then passes through the interior of the connecting member 4 and the movable member 3, and finally flows into the interior of the connecting groove 37 through the plug hole 12 opened on the upper side of the movable member 3. Then, the filtered and softened water flows from the connecting groove 37 into the regulating hole 38 and into the outlet pipe through the water outlet 33. In this process, all the water to be filtered is filtered and softened, and finally flows out of the device, which is the maximum filtered and softened state of the device.

[0054] If the user needs to adjust the softening treatment degree of the device according to the use requirements, the user needs to turn the adjusting knob 51. The rotation of the adjusting knob 51 can drive the adjusting shaft 49 to rotate. Since the adjusting shaft 49 is movably plugged into the plug hole 12 opened on the movable part 3, the adjusting shaft 49 can drive the movable part 3 to rotate. Since the internal thread 10 on the diverter shell 2 and the external thread 11 on the movable part 3 are threadedly connected, the movable part 3 will gradually move upward after rotation. The two mounting rings 16 installed on the movable part 3 and the first sealing ring 19 installed in the first mounting groove 17 opened on the two mounting rings 16 will also move upward with the movable part 3. When the first sealing ring 19 on the lower side of the two first sealing rings 19 on the movable part 3 moves between the opening positions of the first diverter hole 13 and the second diverter hole 14 (such as Figure 7 As shown in FIG5 ), the water to be filtered will enter the interior of the diverter housing 2 through the first diverter hole 13, and then the water to be treated will flow to the lower part of the diverter housing 2 through the plurality of first filter holes provided on the upper filter plate 25. Since the space between the upper filter plate 25 and the lower filter plate 26 is filled with filter material, the water to be filtered will pass through the filter material and then enter the interior of the bottom cover 5 through the plurality of second filter holes provided on the lower filter plate 26. Then, the water will enter the interior of the connecting nozzle 21 through the plurality of communicating holes 23 provided on the connecting nozzle 21. Then, the water simply filtered by the filter material will be mixed with the filtered and softened water, which can reduce the degree of softening of the water of the device to a certain extent, thereby achieving the purpose of regulating the softened water.

[0055] If the user continues to rotate the movable member 3, the lower first sealing ring 19 of the two first sealing rings 19 on the movable member 3 moves to between the opening positions of the second diversion hole 14 and the third diversion hole 15 (such as Figure 8 As shown in FIG1 , the water to be filtered will enter the interior of the diversion shell 2 through the first diversion hole 13 and the second diversion hole 14, thereby increasing the water flow into the diversion shell 2, and more water that has been simply filtered by the filter material will be mixed with the filtered and softened water, which can reduce the degree of water softening of the device to a greater extent;

[0056] Finally, if the user continues to rotate the movable member 3, the lower first sealing ring 19 of the two first sealing rings 19 on the movable member 3 moves to the upper side of the opening position of the third diversion hole 15 (such as Figure 9 As shown in FIG. 1 ), the water to be filtered will enter the interior of the diversion shell 2 through the first diversion hole 13, the second diversion hole 14, and the third diversion hole 15, so that the water flow entering the diversion shell 2 is maximized, and then the water that has been simply filtered by the filter material is mixed with the filtered and softened water, which can minimize the degree of water softening of the device;

[0057] Through the four adjustment states of the device, different degrees of softened water can be obtained to meet the user's needs.
