[0026] In some embodiments, it also includes:

[0027] A hot water system, which is connected to the water purification system, is used to provide users with hot water that has been softened by the water softening system and purified by the water purification system.

[0055] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0056] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements.

[0058] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0059] Please refer to Figure 1-4 This application provides a water purifier 001, which includes a housing assembly 10, a soft water system 002, a water purification system 003, and a mineral water pipeline 006.

[0060] The housing assembly 10 has an inner cavity 10A, in which the water softening system 002 and the water purification system 003 are both installed. The housing assembly 10 protects the water softening system 002 and the water purification system 003, reducing the probability of damage to these systems. It is understood that the housing assembly 10 can be made of at least one of metal and plastic. For example, the housing assembly 10 can be made of metal to give it high structural strength, reducing the probability of damage and consequently reducing the probability of damage to the water softening system 002 and the water purification system 003, thus extending the service life of the water purifier 001. Alternatively, the housing assembly 10 can be made of plastic, which reduces weight and material costs while ensuring structural strength.

[0061] The water softening system 002, serving as a water pretreatment unit, includes a water softening valve 020, a resin tank 010, and a brine tank 030. The water softening valve 020 has an inlet raw water channel, an outlet raw water channel, and a first outlet softened water channel. The inlet raw water channel connects the raw water inlet to the resin tank 010, allowing the incoming raw water to be transported to the resin tank 010 for softening. The outlet raw water channel connects to the inlet raw water channel and is used to output raw water that has not undergone softening in the resin tank 010. The water softening valve 020 may also include a channel connecting the brine tank 030 and the resin tank 010; the resin tank 010 softens hard water into soft water; the brine tank 030 stores regenerated salt, which can enter the resin tank 010 via the water softening valve 020 to regenerate the resin in the resin tank 010.

[0062] Please refer to Figure 4 The water purifier 001 may also include a controller. When the soft water mode is activated, the controller can open the raw water inlet channel. At this time, hard water can enter the resin tank 010 through the soft water valve 020. The sodium ions on the resin in the resin tank 010 can exchange with the calcium and magnesium ions in the hard water, thereby adsorbing the calcium and magnesium ions, turning the hard water into soft water, and storing it in the resin tank 010.

[0063] When all sodium ions on the resin are converted into calcium and magnesium ions, the resin reaches saturation. At this point, the resin loses its ability to soften hard water, and the controller can control the soft water system 002 to start the regeneration mode. It is understood that the controller can control the soft water system 002 to start the regeneration program at preset intervals to regenerate the resin, thereby ensuring that users can access soft water. For example, the preset interval can be 12 hours, 24 hours, 36 hours, etc. In this embodiment, no specific limitation is made to the preset interval.

[0064] Please refer to Figure 4 When the regeneration mode is activated, the controller closes the first soft water outlet channel and connects the soft water valve 020 to the raw water inlet channel and the brine tank, allowing the raw water to contact the regenerated salt in the brine tank 030 and dissolve the regenerated salt to form brine. In another embodiment, the controller can also connect the soft water valve 020 to the resin tank 010 and the brine tank 030. In this case, hard water enters the resin tank 010 via the soft water valve 020 and then flows from the resin tank 010 into the brine tank 030 via the soft water valve 020. After entering the brine tank 030, the water in the resin tank 010 contacts the regenerated salt in the brine tank 030 and dissolves the regenerated salt to form brine. The soft water valve 020 can draw the brine from the brine tank 030 into the resin tank 010, using sodium ions in the brine to replace calcium and magnesium ions on the resin, thereby restoring the resin's softening ability.

[0065] The water purification system 003 may include multiple filter cartridges, which can be installed independently or integrated into a composite filter cartridge. Please refer to [link / reference needed]. Figure 1-4More specifically, the water purification system 003 may include a filtration system 50, which includes a primary filter element and a secondary filter element. The primary filter element may be a pre-filter element 5011, and the secondary filter element may be a reverse osmosis filter element 502. The inlet of the pre-filter element 5011 is connected to the inlet of the filtration system 50, the outlet of the pre-filter element 5011 is connected to the inlet of the reverse osmosis filter element 502, and the outlet of the reverse osmosis filter element 502 is connected to the outlet of the filtration system 50.

[0066] The aforementioned first soft water outlet channel is connected to the inlet of the water purification system 003, that is, to the pre-filter 5011. The soft water system 002 can soften hard water rich in calcium and magnesium ions into soft water, that is, the soft water system 002 can adsorb calcium and magnesium ions in hard water, so that the first soft water outlet channel outputs soft water to the water purification system 003. This reduces the probability of calcium and magnesium ions accumulating in large quantities at the filter element of the water purification system 003, ensuring that the filter element has a normal service life. After being filtered by the water purification system 003, the soft water can provide pure water to the user. The soft water valve 020 also includes a second soft water outlet channel, which is connected to the resin tank 010, and this second soft water outlet channel can provide soft water to the user.

[0067] Pre-filter 5011, serving as the first filtration barrier in the water purification system 003, primarily performs preliminary filtration of the softened water output from the softened water system 002. Its core function is to intercept large particles such as sediment, rust, insect eggs, and red worms in the softened water, preventing these impurities from entering the subsequent reverse osmosis filter 502, thereby extending the lifespan of the reverse osmosis membrane and improving filtration efficiency. Pre-filter 5011 can be of various types, including PP cotton filter (polypropylene melt-blown filter), activated carbon filter, ultrafiltration filter, composite filter, or quartz sand filter. Each filter has different filtration characteristics: PP cotton filter removes large particles through physical interception; activated carbon filter adsorbs residual chlorine, odors, and some organic matter; ultrafiltration filter further retains colloids and microorganisms; composite filter combines multiple filter materials to provide a more comprehensive pretreatment effect; and quartz sand filter is suitable for the preliminary filtration of high-turbidity water sources. This versatile 5011 pre-filter configuration allows for flexible selection based on specific water quality conditions and user needs, ensuring that the 003 water purification system can operate efficiently and stably in various environments.

[0068] The 502 reverse osmosis filter cartridge features a reverse osmosis membrane, which can be an artificial semi-permeable membrane with extremely small pore sizes, typically below 0.0001 micrometers. This ultra-micropore structure allows the reverse osmosis membrane to efficiently intercept various impurities in the water, including dissolved salts, colloids, microorganisms, and organic matter. Driven by pressure provided by a booster pump, water molecules can pass through the reverse osmosis membrane, while most dissolved solids, heavy metal ions, bacteria, viruses, and organic pollutants are retained and discharged with the wastewater. This highly efficient filtration mechanism enables the 502 reverse osmosis filter cartridge to produce high-purity drinking water, meeting users' stringent requirements for water safety and health.

[0069] In other embodiments, the filtration system 50 may further include a post-filter cartridge, the inlet of which is connected to the outlet of the reverse osmosis filter cartridge 502, and the outlet of which is connected to the outlet of the filtration system 50. The post-filter cartridge is used to adsorb odors and residual chlorine, and can be used to improve the taste of room temperature water. The post-filter cartridge can be configured similarly to the pre-filter cartridge 5011. It is understood that the pre-filter cartridge 5011 and the post-filter cartridge can be integrated into a single-stage filter cartridge, so that when the user replaces the single-stage filter cartridge, both the pre-filter cartridge 5011 and the post-filter cartridge can be replaced simultaneously, thereby improving filter cartridge replacement efficiency.

[0070] It is understood that, in the embodiments of this application, the filtration system 50 may also include only the reverse osmosis filter element 502, which is used to filter impurities in the water in one step to provide pure water to the user.

[0071] Please refer to Figure 1-4 In order to facilitate the removal of impurities removed by the filtration system 50, the water purification system 003 also includes a wastewater drainage pipe 54. The wastewater drainage pipe 54 includes a wastewater drainage pipe 541 and a wastewater valve 542. The wastewater drainage pipe 541 is connected to the wastewater outlet of the filtration system 50, and the wastewater valve 542 is installed on the wastewater drainage pipe 541. The wastewater valve 542 is used to control the discharge of wastewater.

[0072] It is understood that the wastewater drain pipe 54 can be connected to the wastewater outlet of the pre-filter 5011 and the wastewater outlet of the reverse osmosis filter 502. In other embodiments, the wastewater drain pipe 54 may also be connected only to the wastewater outlet of the reverse osmosis filter 502.

[0073] Please refer to Figure 1-4Furthermore, since the reverse osmosis filter element 502 has working water pressure requirements, the water purification system 003 also includes a booster pump 80. The booster pump 80 is located upstream of the reverse osmosis filter element 502 and can boost the water pressure to the working pressure range required by the reverse osmosis membrane, ensuring the membrane can operate normally and achieve stable water production and good filtration effect. The booster pump 80 is a variable frequency booster pump, which can dynamically adjust its operating frequency and output pressure according to the actual needs of the water purification system 003. Through its built-in intelligent control system, the variable frequency booster pump monitors the working status and inlet water pressure of the reverse osmosis filter element 502 in real time, automatically adjusting the pump speed to ensure the reverse osmosis membrane is always within the optimal working pressure range. This not only improves the filtration efficiency and water production stability of the reverse osmosis filter element 502 but also significantly reduces energy consumption, avoiding energy waste and equipment wear caused by frequent start-stop cycles of traditional fixed frequency pumps. In addition, the variable frequency booster pump operates with lower noise, further enhancing the user experience. Through intelligent pressure regulation and energy-saving operation, the variable frequency booster pump provides efficient, stable, and environmentally friendly power support for the water purification system 003.

[0074] Furthermore, the water purification system 003 may also include a pure water return pipeline and a pure water quality detection device 0034. The pure water quality detection device 0034 is located downstream of the reverse osmosis filter element 502 and is used to detect the total dissolved solids (TDS) value of the pure water filtered by the reverse osmosis filter element 502. The pure water return pipeline connects the downstream of the reverse osmosis filter element 502 to the upstream of the booster pump 80, enabling a portion of the filtered pure water to be returned to the upstream of the booster pump 80 for secondary filtration. Specifically, when the pure water quality detection device 0034 detects that the total dissolved solids value of the pure water exceeds a preset threshold, the controller will activate the pure water return pipeline, re-sending the substandard pure water to the upstream of the booster pump 80 for further filtration by the reverse osmosis filter element 502 until the TDS value of the pure water reaches the standard, ensuring the stability of the effluent water quality.

[0075] The pure water return pipeline includes a pure water return pipe 561 and a pure water return control component 562. The pure water return pipe 561 connects the downstream of the reverse osmosis filter element 502 to the upstream of the booster pump 80, and is used to return a portion of the filtered pure water to the upstream of the booster pump 80 for secondary filtration. The pure water return control component 562 is installed on the pure water return pipe 561 and is used to control the on / off state and flow rate of the return water. The pure water return control component 562 can be a pure water return check valve to ensure that the water flows only in the return direction, avoiding backflow contamination.

[0076] The water purification system 003 also includes a pure water outlet valve 003a. The inlet of the pure water outlet valve 003a is connected to the outlet of the filtration system 50, and is used to control the discharge of pure water. By adjusting its opening and closing state, the pure water outlet valve 003a can precisely control the output flow rate and timing of pure water. When a user needs to use pure water, the pure water outlet valve 003a opens, and the pure water generated by the filtration system 50 flows through the pure water outlet valve 003a to other water outlet terminals for direct drinking or use by the user. When the system detects that no water supply is needed, the pure water outlet valve 003a closes to avoid water waste.

[0077] The mineral water pipeline 006 is directly connected to the raw water inlet via a connection to the raw water outlet. The mineral water pipeline 006 includes a second mineral water pipeline 0062, a primary filter element 0063, and a second on-off valve 0065. The second mineral water pipeline 0062 is connected to the raw water outlet; the primary filter element 0063 is located within the second mineral water pipeline 0062; and the second on-off valve 0065 is located within the second mineral water pipeline 0062 to control its opening and closing. The mineral water pipeline 006 directly introduces raw water, which undergoes basic filtration only through the primary filter element 0063 (which can be configured similarly to the pre-filter element 5011, such as PP cotton or activated carbon) to remove impurities such as sediment, rust, and residual chlorine, while fully retaining natural minerals such as calcium, magnesium, and potassium. This limited treatment method avoids the complete stripping of trace elements by deep purification technologies (such as RO reverse osmosis), providing users with drinking water that is closer to the quality of natural mineral water, especially suitable for daily consumption to supplement the body's nutritional needs.

[0078] In practical implementation, the primary filter element 0063 and the pre-filter element 5011 can be the same filter element or two independent filter elements. When using the same filter element, both the raw water outlet channel and the first soft water outlet channel of the softening water valve 020 are connected to this filter element. When the softening water valve 020 outputs raw water, the raw water flows to the outlet of the mineral water pipe after being filtered by this filter element; when the softening water valve 020 outputs soft water, the soft water flows to the water purification system 003 after being filtered by this filter element. This solution can reduce the number of filter elements and effectively reduce the size of the water purifier 001. In the solution where the primary filter element 0063 and the pre-filter element 5011 are two independent filter elements, the raw water outlet channel is connected to the primary filter element 0063, and the first soft water outlet channel is connected to the pre-filter element 5011.

[0079] The mineral water pipeline 006 may also include a flow restrictor 0066, which is installed in the second mineral water pipeline 0062 and limits the maximum flow rate of the mineral water pipeline through a fixed orifice or an adjustable structure. This eliminates the problem of fluctuating water flow caused by raw water pressure fluctuations (such as changes in municipal water supply pressure) and ensures uniform water flow. In addition, when the second on / off valve 0065 suddenly opens or closes, the flow restrictor 0066 can buffer the water flow impact, reduce the risk of pipeline vibration and joint leakage, thereby improving the reliability and durability of the system.

[0080] To further meet users' water needs, the water purifier 001 also includes a hot water system 004, which is connected to the water purification system 003 and is used to store and heat the filtered pure water so as to meet users' hot water needs at any time, thus improving the functionality and practicality of the equipment.

[0081] Please refer to Figure 4 It is understandable that the water purifier 001 may also include a water dispenser 57. After passing through a one-way valve, room temperature water can enter the water dispenser 57 to supply water to the water dispenser 57. The water dispenser 57 can also directly provide hot water or cold water.

[0082] In this application, softened water is directly output through the second soft water outlet of the soft water system 002 to meet the needs of domestic water use such as washing and bathing, avoiding the scale problem caused by hard water. The water purification system 003 provides pure water, ensuring the purity and safety of drinking water. Meanwhile, the mineral water pipeline 006 retains the natural trace elements in the raw water, providing users with a mineral-supplemented drinking water option. Furthermore, the hot water system 004 can provide users with hot purified water. This differentiated design solves the problem of "overly pure water" caused by the complete removal of minerals in traditional water purifiers, while avoiding damage to the equipment from hard water, achieving a balance between health needs and practical functions. Moreover, soft water pretreatment significantly reduces the burden on the water purification system 003. For example, before the softened water enters the RO reverse osmosis membrane, calcium and magnesium ions, which are prone to scaling, are removed, delaying membrane fouling, improving desalination efficiency, extending filter life, and reducing wastewater caused by membrane clogging. Because the hot water system 004 uses purified water, the heating element and inner tank are less prone to scale buildup, resulting in stable heat transfer efficiency and reduced energy consumption and maintenance frequency.

[0083] Please refer to the moon. Figures 4 to 6The water purifier 001 may include a faucet 1A, which is integrated into the housing assembly 10. Alternatively, the water purifier 001 may not include a faucet 1A, but may have a faucet 1A connected to an external source (e.g., the kitchen). Specifically, the faucet 1A may be connected to, or a combination thereof, or all of the outlets of the mineral water pipeline 006, the water purification system 003, the soft water system 002, and the hot water system 004. Thus, when a user takes pure water from faucet 1A, the soft water in resin tank 010 can flow out through the first soft water outlet channel of soft water valve 020 and enter the water purification system 003. After being filtered by the water purification system 003, the soft water can be directly output to faucet 1A to provide the user with room temperature pure water. After being filtered by the water purification system 003, the soft water can also be output to the heating tank assembly 20 or the water dispenser 57 for heating, and then output to faucet 1A through the heating tank assembly 20 to provide the user with hot water, or directly provide the user with hot water through the water dispenser 57.

[0084] It is understood that the water purifier 001 can have three faucets 1A: one faucet 1A is connected to the hot water system 004, another faucet 1A is connected to the water purification system 003, and the third faucet 1A is connected to the mineral water pipeline 006, thus providing users with hot water, room temperature water, and mineral water independently. In other embodiments, the faucet 1A can also be connected to the hot water system 004, the water purification system 003, and the mineral water pipeline 006 respectively, and the flow of hot water or room temperature water can be controlled by a switch.

[0085] It is understandable that faucet 1A can also be a smart faucet 1A. When the controller detects a signal for drawing room temperature water or a water replenishment signal from the hot water system 004 at the smart faucet 1A, the controller can control the water purification system 003 to start water production, so as to ensure that users can get room temperature water and hot water from the smart faucet 1A in a timely manner, reduce the user's waiting time, and improve the user experience.

[0086] To improve the heating efficiency of the hot water system 004, this application makes further improvements to the hot water system 004. Please refer to... Figures 7 to 11The hot water system 004 includes a hot water tank assembly 20, a water pump 30, and a second sealing ring 33. The hot water tank assembly 20 includes a tank body 21 and a heating element 22. The tank body 21 has a heating chamber 21a, and the heating element 22 can be installed inside the heating chamber 21a to heat the water inside. In other embodiments, the heating element 22 can also be installed outside the heating chamber 21a, for example, embedded in the tank body 21, or arranged around the outer surface of the tank body 21; this application does not limit this. The tank body 21 has a water outlet 216 communicating with the heating chamber 21a, and the water outlet 216 is located at the lower part of the tank body 21. The tank body 21 includes a tank body 211, a top cover 212, and a bottom cover 213, which together form the heating chamber 21a.

The second connecting hole 30A2 can be a threaded hole, and the fastener can be a screw 38. The screw 38 extends outward from the inside of the tank 21 through the first connecting hole 21b, then passes through and is fixed in the second connecting hole 30A2, and is threadedly connected to the second connecting hole 30A2. This connection method has high stability and is simple to install. Of course, in other embodiments, the tank 21 and the pump housing 30A1 can also be connected by snap-fit.

[0092] Please see Figure 10 In some embodiments, the outer wall of the pump housing 30A1 is provided with a second annular limiting portion surrounding the second connecting hole 30A2, and the third sealing ring 34 is limited within the second annular limiting portion. The second annular limiting portion can relatively fix the third sealing ring 34, improving the sealing performance between the water pump 30 and the tank 21. In some embodiments, the second annular limiting portion is a second annular groove 362, and the third sealing ring 34 is installed in the second annular groove 362, and partially protrudes outward to abut against the tank 21. The second annular limiting portion and the connection form between the second annular limiting portion and the third sealing ring 34 can be set with reference to the connection form between the first annular limiting portion and the second sealing ring 33 described above.

[0093] Please refer to 8 to Figure 10 In some embodiments, the outer diameter of the pump inlet 351 is smaller than the outer diameter of the outlet 216. The top of the pump casing 30A1 is provided with at least two opposing positioning parts 37. The positioning parts 37 are located on the outside of the pump inlet 351, and the outer wall of the positioning parts 37 abuts against the inner wall of the outlet 216 to ensure that the pump casing 30A1 and the tank 21 are connected in the correct position, thereby improving the stability of the connection between the pump inlet 351 and the outlet 216.

[0094] Furthermore, the outer wall surface of the positioning part 37 is formed with a guide surface 371 and a limiting surface 372 connected sequentially from top to bottom. The guide surface 371 extends toward the limiting surface 372, and the limiting surface 372 abuts against the inner wall of the outlet 216. The guide surface 371 can guide the positioning part 37 into the outlet 216 during installation, and when installed in place, the limiting surface 372 abuts against the inner wall surface of the outlet 216.

[0095] Please see Figure 10 and Figure 11 The pump housing 30A1 also includes a water pump outlet 352, and the heated tank assembly 20 also includes a water outlet pipe 27. One end of the water outlet pipe 27 is connected to the water pump outlet 352, and part of it extends into the tank body 21 and out of the tank body 21. In this way, the water in the water outlet pipe 27 will be further heated by the water in the tank body 21 before flowing out to the outside, thereby increasing the temperature of the first cup of water.

[0096] Please refer to the reference.
