[0039] Reference below Figure 1-Figure 3 A water production system 100 according to an embodiment of the present invention is described.

[0040] like Figure 1-Figure 3 As shown, according to the water production system 100 of the embodiment of the present invention, the water production system 100 may have a water inlet 400 and a first water outlet 200 ( Figure 2 As shown), the water inlet 400 can be connected to a water source (such as a reservoir, a tap water pipe) to facilitate the access of unpurified water to the water production system 100, and the pure water purified by the water production system 100 can flow out through the first water outlet 200 for user use.

[0041] The water production system 100 may include a pre-filter element 52, a reverse osmosis filter element 53, a mineralized filter element 54 and a first drive element 55. The inlet of the pre-filter element 52 may be connected to the water inlet 400, and the inlet of the reverse osmosis filter element 53 may be connected to the outlet of the pre-filter element 52. The pre-filter element 52 may perform primary filtration on the water, which may reduce the filtration pressure of the reverse osmosis filter element 53 and help to increase the service life of the reverse osmosis filter element 53. For example, the pre-filter element 52 may be composed of polypropylene fiber cotton (PP cotton) and activated carbon, or the pre-filter element 52 may be a polypropylene fiber composite activated carbon (PP composite activated carbon), the reverse osmosis filter element 53 may be an RO membrane reverse osmosis filter element, which may improve the filtration accuracy of water and the filtration effect of water, and the mineralized filter element 54 may be a mineral carbon rod filter element, which may ensure that pure water is in full contact with the mineralized filter element 54.

[0042] The mineralized water inlet of the mineralized filter element 54 can be connected to the pure water outlet of the reverse osmosis filter element 53, so that the pure water filtered by the pre-filter element 52 and the reverse osmosis filter element 53 can flow through the mineralized filter element 54, and the mineralized filter element 54 can add minerals beneficial to the human body (such as calcium, magnesium, strontium, zinc or bicarbonate, etc.) to the pure water. The mineralized water outlet of the mineralized filter element 54 can be connected to the first water outlet 200, so that the pure water added with minerals beneficial to the human body can flow out through the first water outlet 200, which is convenient for users to use.

[0043] And the first driving member 55 can be arranged on the water path between the water inlet 400 and the reverse osmosis filter element 53. The first driving member 55 can drive the water to flow from the water inlet 400 to the first water outlet 200, so that the water in the water production system 100 can flow through the pre-filter element 52, the reverse osmosis filter element 53 and the mineralization filter element 54 in sequence, which can ensure the water purification effect and the mineral concentration of pure water that is beneficial to the human body, thereby ensuring the user's water safety and the user's mineral intake, so that the user can have a normal metabolic level and normal physiological function.

[0044] Among them, a first mineral detection component 11 can be arranged between the mineralized water outlet of the mineralized filter element 54 and the first water outlet 200. The first mineral detection component 11 can detect the mineral concentration of pure water. The water production system 100 can adjust the power of the first driving component 55 according to the user's choice, and the water production system 100 can adjust the power of the first driving component 55 according to the mineral concentration detected by the first mineral detection component 11, that is, the water production system 100 can adjust the flow rate and flow rate of water to control the contact time between pure water and the mineralized filter element 54, so as to achieve the adjustment of the mineral concentration of pure water, and it is beneficial to maintain the mineral concentration of pure water at a stable level, which can improve the user's water use experience. It can be understood that the first driving component 55 can be a variable frequency water pump, so that the water production system 100 can adjust the power of the first driving component 55 (such as the speed of the variable frequency water pump).

[0045] The first mineral detection component 11 can be a total dissolved solid sensor (TDS sensor). The TDS sensor can calculate the TDS value of water by measuring the conductivity of water. For example, when a water sample passes through the TDS sensor, the electrodes inside it will measure the conductivity of the water, and then calculate the TDS concentration of the water, thereby realizing the detection of the TDS value of the water. TDS (Total Dissolved Solids) refers to the total amount of inorganic salts and organic matter contained in water, which can reflect the hardness and salt content of the water. The higher the TDS value of the water, the harder the water quality and the higher the salt content of the water. Conversely, the lower the TDS value of the water, the softer the water quality and the lower the salt content of the water.

[0046] Specifically, the water production system 100 can increase the power of the first driving component 55 according to the user's choice (such as the user wants to drink pure water with a higher concentration of minerals beneficial to the human body) to increase the flow rate and flow of water, thereby reducing the contact time between the pure water and the mineralized filter element 54 to reduce the mineral concentration of the pure water; or, the water production system 100 can lower the power of the first driving component 55 according to the user's choice (such as the user wants to drink pure water with a lower concentration of minerals beneficial to the human body) to lower the flow rate and flow of water, thereby increasing the contact time between the pure water and the mineralized filter element 54 to increase the mineral concentration of the pure water.

[0047] Of course, the water production system 100 can automatically increase the power of the first driving component 55 according to the mineral concentration detected by the first mineral detection component 11 (such as the mineral concentration detected by the first mineral detection component 11 is too high) to increase the flow rate and flow of water, thereby reducing the contact time between the pure water and the mineralized filter element 54 to automatically reduce the mineral concentration of the pure water; or, the water production system 100 can automatically reduce the power of the first driving component 55 according to the mineral concentration detected by the first mineral detection component 11 (such as the mineral concentration detected by the first mineral detection component 11 is too low) to reduce the flow rate and flow of water, thereby increasing the contact time between the pure water and the mineralized filter element 54 to automatically increase the mineral concentration of the pure water.

[0048] According to the water production system 100 of the embodiment of the present invention, by setting a mineralization filter element 54 after the pre-filter element 52 and the reverse osmosis filter element 53, the water production system 100 can add minerals beneficial to the human body to the filtered pure water, thereby ensuring the water purification effect and the concentration of minerals beneficial to the human body in the pure water, thereby ensuring the user's water safety and the user's mineral intake, so that the user can have a normal metabolic level and normal physiological function.

[0049] Furthermore, by arranging the first mineral detection component 11 behind the mineralized filter element 54, the mineral concentration of pure water can be detected, so that the water production system 100 can adjust the power of the first driving component 55 according to the mineral concentration of pure water, that is, the water production equipment 1000 can adjust the flow rate and flow of water according to the mineral concentration of pure water to control the contact time between pure water and the mineralized filter element 54, thereby realizing the adjustment of the mineral concentration of pure water, and is beneficial to maintaining the mineral concentration of pure water at a stable level, which can improve the user's water use experience.

[0050] like Figure 1 As shown, according to some embodiments of the present invention, after the water production system 100 stops producing water, the water production system 100 can automatically record the user's water consumption until the water production system 100 restarts to produce water. If the user's water consumption is less than the water storage capacity (such as capacity or volume) of the mineralized filter element 54, the contact time between the pure water in the mineralized filter element 54 and the mineralized filter element 54 is too long, resulting in a higher mineral concentration in the water output from the water production system 100 after the water production is restarted. If the user's water consumption is greater than the water storage capacity of the mineralized filter element 54, the contact time between the pure water in the mineralized filter element 54 and the mineralized filter element 54 is too short, resulting in a lower mineral concentration in the water output from the water production system 100 after the water production is restarted.

[0051] Among them, when the water production system 100 restarts to produce water, the water production system 100 can adjust the power of the first driving component 55 according to the user's water consumption and the water storage capacity of the mineralized filter element 54. If the user's water consumption is less than the water storage capacity of the mineralized filter element 54, the water production system 100 can increase the power of the first driving component 55 to increase the flow rate and flow of water, thereby reducing the contact time between the pure water and the mineralized filter element 54 to reduce the mineral concentration of the pure water.

[0052] If the user's water consumption is greater than the water storage capacity of the mineralized filter element 54, the water production system 100 can reduce the power of the first driving member 55 to reduce the flow rate and flow of the water, thereby increasing the contact time between the pure water and the mineralized filter element 54 to increase the mineral concentration of the pure water. In this way, the mineral concentration of the pure water can be maintained at a stable level, which can improve the user's water experience.

[0053] like Figure 1 As shown, according to some embodiments of the present invention, the water production system 100 may also have a second water outlet 300, and the second water outlet 300 may be connected to the mineralized water outlet of the mineralized filter element 54, so that pure water added with minerals beneficial to the human body can flow out through the second water outlet 300, and the second water outlet 300 may be connected to an indoor water inlet 500 (such as a faucet water outlet), so that the pure water at the second water outlet 300 can flow out through the indoor water inlet 500, which is convenient for users to use.

[0054] like Figure 1 As shown, according to some embodiments of the present invention, the water inlet 400 can be connected to the indoor water inlet 600 (such as a tap water pipe), that is, the user can cut off the tap water pipe to divide it into a water supply branch 70 and a faucet 80, the water supply branch 70 can be connected to a water source (such as tap water), and the faucet outlet of the faucet 80 can be an indoor water inlet 500, wherein the water inlet 400 of the water production system 100 can be connected to the water supply branch 70, and the second water outlet 300 of the water production system 100 can be connected to the faucet 80, thereby facilitating the water production system 100 to directly provide the user with pure water added with minerals beneficial to the human body through the faucet 80.

[0055] It can be understood that the water supply branch 70 can be provided with a water inlet valve 57, and the opening and closing of the water inlet valve 57 can control the on-off of the water supply branch 70. For example, the user can close the water inlet valve 57 to stop the water from flowing out of the tap, which is convenient for the installation of the water production system 100 and related equipment, and is conducive to reducing the waste of water during the equipment installation process. Furthermore, after the water production system 100 and related equipment are installed, the user can open the water inlet valve 57 to connect the water production system 100 with the water source, which can ensure the normal operation of the water production system 100, so that the user can manually turn off the water inlet function of the water production system 100, so that the operator can open the water inlet valve 57 after confirming that the installation of the water production system 100 and related equipment is completed to restore the water inlet function of the water production system 100, which can ensure the feasibility of installing the water production system 100 and related equipment.

[0056] like Figure 1 and Figure 3 As shown, in some embodiments, the water production system 100 may further include a water storage tank 58, which may be disposed between the mineralized water outlet of the mineralized filter element 54 and the first water outlet 200, so that pure water added with minerals beneficial to the human body may flow out through the first water outlet 200 after passing through the water storage tank 58, that is, the water storage tank 58 may store pure water added with minerals, thereby ensuring the amount of pure water used by the user each time, and reducing the water production time of the water production system 100, thereby ensuring that the user's water is ready for use, which is convenient for the user to use, and at the same time, the water production frequency of the water production system 100 may be reduced, which is beneficial to increasing the service life of the water production system 100.

[0057] like Figure 1 As shown, in some embodiments, a first mineralized water path 10 and a second mineralized water path 20 may be provided between the mineralized water outlet of the mineralized filter element 54 and the water storage tank 58, that is, one end of the first mineralized water path 10 may be connected to the mineralized water outlet of the mineralized filter element 54, one end of the second mineralized water path 20 may be connected to the other end of the first mineralized water path 10, and the other end of the second mineralized water path 20 may be connected to the water storage tank 58, so that the mineralized water outlet of the mineralized filter element 54 may be connected to the water storage tank 58, so that the water storage tank 58 can store pure water added with minerals, and it is convenient for users to use.

[0058] The water production system 100 may also include a third mineralized water path 30, which can be connected between the first mineralized water path 10 and the second water outlet 300, that is, one end of the third mineralized water path 30 can be connected to the other end of the first mineralized water path 10, and the other end of the third mineralized water path 30 can be connected to the second water outlet 300, so that the mineralized water outlet of the mineralized filter element 54 can be connected to the second water outlet 300, so that the pure water added with minerals can flow out through the second water outlet 300 and the indoor water inlet 500 (such as a faucet outlet) in sequence, which is convenient for users to use.

[0059] The first mineral detection component 11 can be arranged on the first mineralized water channel 10, or the first mineral detection component 11 can be arranged on the second mineralized water channel 20, that is, the first mineral detection component 11 can be arranged at the rear end of the mineralization filter element 54, so as to detect the mineral concentration of pure water added with minerals beneficial to the human body, so that the water production system 100 can adjust the power of the first driving component 55 according to the user's choice, and the water production system 100 can adjust the power of the first driving component 55 according to the mineral concentration detected by the first mineral detection component 11, so as to realize the adjustment of the mineral concentration of pure water, and is conducive to maintaining the mineral concentration of pure water at a stable level, which can improve the user's water use experience.

[0060] It can be understood that the first mineral detection component 11 can be set on the first mineralized water channel 10, so that the first mineral detection component 11 can accurately detect the mineral concentration of the pure water in the first mineralized water channel 10, so that the water production system 100 can adjust the mineral concentration of the pure water in the second mineralized water channel 20 and the mineral concentration of the pure water in the third mineralized water channel 30 according to the mineral concentration of the pure water in the first mineralized water channel 10, that is, the water production system 100 can adjust the mineral concentration of the pure water at the first water outlet 200 and the second water outlet 300 together, which is beneficial to reduce the number of first mineral detection components 11, save costs, and facilitate operation.

[0061] Of course, the first mineral detection component 11 can be set on the second mineralized water channel 20, so that the first mineral detection component 11 can accurately detect the mineral concentration of the pure water in the second mineralized water channel 20, so that the water production system 100 can adjust the mineral concentration of the pure water according to the mineral concentration of the pure water in the second mineralized water channel 20, that is, the water production system 100 can adjust the mineral concentration of the pure water at the first water outlet 200, and can improve the accuracy of adjusting the mineral concentration of the pure water at the first water outlet 200, which can improve the user's water use experience.

[0062] Of course, the first mineral detection component 11 can also be set on the third mineralized water channel 30, so that the first mineral detection component 11 can accurately detect the mineral concentration of the pure water in the third mineralized water channel 30, so that the water production system 100 can adjust the mineral concentration of the pure water according to the mineral concentration of the pure water in the third mineralized water channel 30, that is, the water production system 100 can adjust the mineral concentration of the pure water at the second water outlet 300, and can improve the accuracy of adjusting the mineral concentration of the pure water at the second water outlet 300, which can improve the user's water use experience.

[0063] like Figure 1As shown, in some embodiments, the water production system 100 can have a water pressure switch 12, and a first control valve 51 can be arranged between the pre-filter element 52 and the water inlet 400. The opening and closing of the first control valve 51 can control the on-and-off of the water path between the pre-filter element 52 and the water inlet 400. The water pressure switch 12 can control the operation of other components (such as the first control valve 51 and the first drive member 55) by receiving a low-pressure signal.

[0064] That is, when the first water outlet 200 is connected to the outside world, the water pressure of the pure water in the second mineralized water path 20 can become low, so that the water pressure switch 12 can receive the low-pressure signal and open automatically to control the first drive member 55 to work and open the first control valve 51, which is beneficial to the automatic water production of the water production system 100 and is easy to operate. When the second water outlet 300 is connected to the outside world, the water pressure of the pure water in the third mineralized water path 30 can become low, so that the water pressure switch 12 can receive the low-pressure signal and open automatically to control the first drive member 55 to work and open the first control valve 51, which is beneficial to the automatic water production of the water production system 100 and is easy to operate.

[0065] like Figure 1 As shown, in some embodiments, the first mineralized water path 10 can be provided with a one-way valve 56, which can control the one-way flow of pure water in the first mineralized water path 10, and can prevent the pure water added with minerals beneficial to the human body from flowing back into the mineralized filter element 54, which is beneficial to improving the water production effect of the water production system 100, and is beneficial to improving the service life of the water production system 100. The one-way valve 56 can be located between the water pressure switch 12 and the mineralized water outlet, so that the water pressure switch 12 can directly receive the low-pressure signal generated by the opening of the first water outlet 200 and the second water outlet 300, which can improve the accuracy of the water pressure switch 12 in receiving the low-pressure signal, facilitate the automatic water production of the water production system 100, and improve the user experience.

[0066] Among them, the first mineralized water path 10 can be provided with a first mineral detection component 11, and the first mineral detection component 11 can be arranged between the one-way valve 56 and the mineralized water outlet, or, the first mineral detection component 11 can be arranged between the one-way valve 56 and the water pressure switch 12, or, the first mineral detection component 11 can be arranged between the water pressure switch 12 and the second mineralized water path 20, for easy arrangement.

[0067] At the same time, the mineral concentration of the pure water in the first mineralized water channel 10 can be detected, so that the water production system 100 can adjust the mineral concentration of the pure water in the second mineralized water channel 20 and the mineral concentration of the pure water in the third mineralized water channel 30 according to the mineral concentration of the pure water in the first mineralized water channel 10, that is, the water production system 100 can adjust the mineral concentration of the pure water at the first water outlet 200 and the second water outlet 300 together, which is beneficial to reduce the number of first mineral detection components 11 and save costs.

[0068] like Figure 1 As shown, in some embodiments, a second control valve 21 can be provided between the mineralized water outlet of the mineralized filter element 54 and the water tank 58. The opening and closing of the second control valve 21 can control the on-off of the water path between the mineralized water outlet and the water tank 58, so that pure water added with minerals beneficial to the human body can flow into the water tank 58, that is, the water tank 58 can store pure water added with minerals, and the pure water in the water tank 58 can flow out through the first water outlet 200, which can ensure the amount of pure water used by the user each time, and can ensure that the user's water is used and discharged, which is convenient for the user to use.

[0069] like Figure 1 As shown, in some embodiments, the second water outlet 300 can be connected to a faucet 80, the indoor water inlet 500 can be a faucet water outlet, and the indoor water inlet 500 can be connected to the outside to reduce the water pressure at the second water outlet 300, so that the water pressure switch 12 can receive a low-pressure signal to automatically open when the indoor water inlet 500 is opened, so as to control the first drive member 55 to work and open the first control valve 51, thereby realizing automatic water production of the water production system 100.

[0070] The water pressure switch 12 can receive a high-pressure signal to automatically close when the indoor water inlet 500 is closed, so as to control the first driving member 55 to stop working and close the first control valve 51, that is, the water pressure switch 12 can automatically open when the indoor water inlet 500 is opened, so that the water production system 100 can directly discharge pure water added with minerals beneficial to the human body to the outside through the indoor water inlet 500, and the water pressure switch 12 can automatically close when the indoor water inlet 500 is closed, so that the water production system 100 stops working, thereby ensuring that the user's water is ready for use and easy to operate.

[0071] Of course, the second control valve 21 can be opened to connect the water path between the mineralized filter element 54 and the water tank 58, so that the water pressure switch 12 can receive a low-pressure signal to automatically open when the second control valve 21 is opened, so as to control the first drive member 55 to work and open the first control valve 51, thereby realizing automatic water production of the water production system 100, and the water pressure switch 12 can receive a high-pressure signal to automatically close when the second control valve 21 is closed, so as to control the first drive member 55 to stop working and close the first control valve 51.

[0072] That is, the water pressure switch 12 can be automatically opened when the second control valve 21 is opened, so that the water tank 58 can store pure water added with minerals beneficial to the human body, which is convenient for users to use water later, or the water production system 100 can directly discharge pure water added with minerals beneficial to the human body to the outside through the first water outlet 200, which can ensure that users can use water as soon as possible, and improve the user's water use experience. The water pressure switch 12 can be automatically closed when the second control valve 21 is closed, so that the water production system 100 stops working, which is convenient for operation.

[0073] like Figure 1 As shown, in some embodiments, the second control valve 21 can be automatically opened when the water level in the water tank 58 is lower than a preset water level, that is, when the remaining water in the water tank 58 is small, the second control valve 21 can be automatically opened to allow the water pressure switch 12 to automatically open, thereby controlling the first drive member 55 to work and open the first control valve 51, thereby realizing automatic water production of the water production system 100, and allowing the water tank 58 to be automatically replenished with water, thereby improving the user experience.

[0074] Of course, the second control valve 21 can be automatically opened when the water level change in the water tank 58 is greater than the preset water level change (such as 600 milliliters). That is, when the user uses too much water, the second control valve 21 can be automatically opened to allow the water pressure switch 12 to automatically open, so that the water production system 100 can control the first drive member 55 to work and open the first control valve 51, thereby realizing automatic water production of the water production system 100 and allowing the water tank 58 to automatically replenish water, thereby improving the user experience.

[0075] like Figure 1 As shown, according to some embodiments of the present invention, the water production system 100 may further include a wastewater branch 60, one end of the wastewater branch 60 may be connected to the reverse osmosis filter element 53, and the other end of the wastewater branch 60 may be connected to the outside world, and the reverse osmosis filter element 53 may have a reverse osmosis membrane (RO membrane), which may allow water molecules to pass through, and the reverse osmosis membrane may block impurities such as minerals (including minerals harmful to the human body), heavy metals, bacteria, viruses, and organic matter, and the first driving member 55 may drive the water to flow so that the water molecules pass through the reverse osmosis membrane against the concentration gradient to form pure water.

[0076] Among them, water that does not pass through the reverse osmosis membrane will become concentrated water (wastewater) due to the increase in impurity concentration. The wastewater branch 60 can discharge the wastewater, which can prevent the surface of the reverse osmosis membrane from being blocked, and the wastewater can continue to flow on the surface of the reverse osmosis membrane to flush the reverse osmosis membrane, which can ensure the permeability of the reverse osmosis membrane, thereby ensuring the filtration efficiency of the reverse osmosis filter element 53, and the service life of the reverse osmosis filter element 53 can be improved. The wastewater branch 60 can have a wastewater valve 61, and the opening and closing of the wastewater valve 61 can control the on-off of the wastewater branch 60. The water production system 100 can open the wastewater valve 61 during water production to allow the wastewater branch 60 to discharge the wastewater, which can ensure the normal operation of the reverse osmosis filter element 53 and the water production effect of the water production system 100.

[0077] like Figure 1 As shown, in some embodiments, the water production system 100 may further include a return branch 40, and the pure water outlet of the reverse osmosis filter element 53 may be connected to the inlet of the reverse osmosis filter element 53 through the return branch 40. The reverse osmosis filter element 53 may have a reverse osmosis membrane (RO membrane), which can filter water (such as tap water) so that the outlet side of the reverse osmosis filter element 53 is pure water, and the minerals in the water (such as tap water) can be retained on the inlet side of the reverse osmosis filter element 53.

[0078] However, after the water production system 100 stops producing water, the minerals on the water inlet side of the reverse osmosis filter element 53 will penetrate into the pure water on the water outlet side of the reverse osmosis filter element 53 through the reverse osmosis membrane, and the pure water on the water outlet side of the reverse osmosis filter element 53 is prone to breed bacteria and become stale water when it is not flowing for a long time. Therefore, if the water production system 100 resumes water production after stopping water production, the stale water mixed with the above-mentioned minerals (including minerals harmful to the human body) will flow through the mineralization filter element 54, making it difficult to ensure the stability of the mineral concentration of the water produced by the water production system 100 and to ensure the safety of the user's water use.

[0079] Among them, the return water branch 40 can be provided with a third control valve 41, and the opening and closing of the third control valve 41 can control the on-off of the return water branch 40, so that the first control valve 51 and the third control valve 41 can be opened and the first drive member 55 can work, so that the stale water located at the pure water outlet of the reverse osmosis filter element 53 can flow back to the inlet of the reverse osmosis filter element 53 and flow through the reverse osmosis filter element 53 again, and multiple filtration of the stale water can be achieved.

[0080] Therefore, when the water production system 100 produces water again, stale water mixed with the above-mentioned minerals (including minerals harmful to the human body) can be prevented from flowing through the mineralized filter element 54, thereby ensuring that the mineral concentration of the pure water added with minerals beneficial to the human body produced by the water production system 100 is stable. It should be noted that the return water branch 40 can be provided with a one-way valve 56, which can control the one-way circulation flow of water in the return water branch 40, thereby improving the filtering effect of stale water and ensuring the water safety of users.

[0081] like Figure 1 As shown, in some embodiments, when the closing time of the water pressure switch 12 is greater than the preset time (such as twenty minutes), that is, when the water production system 100 stops producing water for more than the preset time, the water production system 100 can automatically open the third control valve 41 before starting to produce water, so that the first driving member 55 can drive water (such as tap water and stale water) to circulate in the return branch 40 until the outlet side of the reverse osmosis filter element 53 is filled with pure water. At this time, the water production system 100 can close the third control valve 41 and start to produce water, which can prevent stale water mixed with the above-mentioned minerals (including minerals harmful to the human body) from flowing through the mineralized filter element 54, thereby ensuring that the mineral concentration of the pure water added with minerals beneficial to the human body produced by the water production system 100 is stable, and the user's water safety can be guaranteed.

[0082] It can be understood that the reverse osmosis filter element 53 can circulate and filter stale water so that the outlet side of the reverse osmosis filter element 53 is filled with pure water, and because the water that has not passed through the reverse osmosis membrane will become concentrated water (wastewater) on the inlet side of the reverse osmosis filter element 53 due to the increase in impurity concentration, the water production system 100 can open the wastewater valve 61 when the third control valve 41 is opened to allow the wastewater branch 60 to discharge wastewater, which can prevent the surface of the reverse osmosis membrane from being blocked, and the wastewater can continue to flow on the surface of the reverse osmosis membrane to flush the reverse osmosis membrane, thereby ensuring the filtration efficiency of the reverse osmosis filter element 53 and increasing the service life of the reverse osmosis filter element 53.

[0083] like Figure 1 As shown, in some embodiments, the water inlet valve 57 can be a three-way ball valve, which can improve the durability of the water inlet valve 57 and the reliability of the user opening and closing the water inlet valve 57, thereby improving the feasibility of installing the water production system 100 and related equipment. The first control valve 51 can be an electric valve, which can realize automatic control of water inlet of the water production system 100, the second control valve 21 can be an electric valve, which can realize automatic control of the on-off of the second mineralized water path 20 by the water production system 100, the third control valve 41 can be an electric valve, which can realize automatic control of the on-off of the return water branch 40 by the water production system 100, and the wastewater valve 61 can be an electric valve, which can realize automatic control of the on-off of the wastewater branch 60 by the water production system 100, which is easy to operate and is conducive to improving the user experience.

[0084] According to some embodiments of the present invention, the manufacturing process of the mineralized filter element includes: acid-treating carbonate rock; high-temperature calcining the acid-treated carbonate rock; and carbonating the high-temperature calcined carbonate rock to obtain rock filter material.

[0085] Therefore, by adopting at least one of the above three production processes, the natural rock weathering and leaching of rocks rich in beneficial elements can be simulated, thereby increasing the dissolution rate of minerals when the rocks come into contact with water and improving the working effect of the mineralization filter element.

[0086] In some embodiments, acid treatment of carbonate rock includes: soaking carbonate rock with food-grade sodium citrate of a certain concentration at a predetermined temperature; filtering carbonate rock after time t1 and washing with purified water.

[0087] Therefore, by soaking carbonate rock with food-grade sodium citrate under predetermined constant temperature conditions, the blind pores inside the carbonate rock can be opened, which can ensure that pure water can enter the interior of the rock, and the working efficiency of the mineralized filter element can be improved. By allowing water to flow through the interior of the rock to filter the carbonate rock and washing it with pure water, the carbonate rock treated with acid can be obtained, and the qualified rate of the mineralized filter element can be improved.

[0088] In some embodiments, the acid-treated carbonate rock is calcined at a temperature of 650°C to 800°C.

[0089] Therefore, by placing the acid-treated carbonate rock in a muffle furnace for high-temperature calcination, the porosity of the carbonate rock can be increased, thereby enhancing the contact area between the carbonate rock and water, increasing the ability of the carbonate rock to precipitate minerals, and improving the working effect of the mineralized filter element.

[0090] In some embodiments, carbonating the carbonate rock calcined at high temperature to obtain the rock filter material includes: placing the carbonate rock calcined at high temperature in a tubular furnace device, introducing carbon dioxide of a predetermined concentration, and performing carbonation modification at a predetermined temperature.

[0091] Therefore, by placing the carbonate rock calcined at high temperature in a quartz tube in a tubular furnace equipment so that the carbonate rock can be carbonated and modified under carbon dioxide and a high temperature of 450°C, the crystal structure of the carbonate rock can be changed, and the continuous cavitation ability of the carbonate rock can be enhanced, thereby ensuring that the carbonate rock continuously precipitates minerals for a long time and prolonging the service life of the mineralized filter element.

[0092] In some embodiments, the manufacturing process of the mineralized filter element further includes: sintering the rock filter material with carbon powder and a binder into a carbon rod and packaging the carbon rod.

[0093] Therefore, by sintering the rock filter material with carbon powder and adhesive into a carbon rod and encapsulating it into a mineralized filter element, the dissolution effect of minerals when pure water flows through the mineralized filter element can be improved, the working effect of the mineralized filter element can be improved, and the service life of the mineralized filter element can be increased. Of course, the operator can directly encapsulate the rock filter material into a mineralized filter element, which can ensure the dissolution effect of minerals when pure water flows through the mineralized filter element and save costs.

[0094] like Figure 1 , Figure 2 and Figure 3 As shown, the water production equipment 1000 according to an embodiment of the present invention includes a water production system 100. By adopting the above-mentioned water production system 100, the water production equipment 1000 can add minerals beneficial to the human body to the filtered pure water, thereby ensuring the water purification effect and the mineral concentration of the pure water beneficial to the human body, thereby ensuring the user's water safety and the user's mineral intake, so that the user can have a normal metabolic level and normal physiological function.

[0095] Refer to the following Figure 1 , Figure 2 and Figure 3 To describe a specific embodiment of the present application, the water production equipment 1000 may include a water production system 100, a first water outlet 200 and a water inlet 400. The water production system 100 may include a first mineralized water path 10, a second mineralized water path 20, a return water branch 40, a pre-filter element 52, a reverse osmosis filter element 53, a mineralized filter element 54, a variable frequency water pump and a water storage tank 58. The inlet of the pre-filter element 52 can be connected to the water inlet 400, the inlet of the reverse osmosis filter element 53 can be connected to the outlet of the pre-filter element 52, and the mineralized water inlet of the mineralized filter element 54 can be connected to the pure water outlet of the reverse osmosis filter element 53.

[0096] The mineralized water outlet of the mineralized filter element 54 can be connected to one end of the first mineralized water channel 10, the other end of the first mineralized water channel 10 can be connected to one end of the second mineralized water channel 20, the other end of the second mineralized water channel 20 can be connected to the water storage tank 58, the water storage tank 58 can be connected to the first water outlet 200, and the pure water outlet of the reverse osmosis filter element 53 can be connected to the inlet of the reverse osmosis filter element 53 through the return water branch 40.

[0097] Among them, a first control valve 51 can be provided between the pre-filter element 52 and the water inlet 400, a variable frequency water pump can be provided in the water channel between the water inlet 400 and the reverse osmosis filter element 53, the first mineralized water channel 10 can be provided with a first mineral detection component 11 and a water pressure switch 12, the second mineralized water channel 20 can be provided with a second control valve 21, and the return water branch 40 can be provided with a third control valve 41.

[0098] The water production system 100 can start to produce water, that is, the water production system 100 can control the second control valve 21 to open, so that the water pressure switch 12 controls the first control valve 51 to open by receiving the low-pressure signal, and controls the variable frequency water pump to start working. The tap water can flow through the pre-filter 52 and the reverse osmosis filter 53 in sequence to become pure water, and the pure water can flow through the mineralization filter 54 to become pure water added with minerals beneficial to the human body, so that the water storage tank 58 can store pure water added with minerals beneficial to the human body, and the pure water added with minerals beneficial to the human body can flow out from the first water outlet 200.

[0099] Of course, if the water production system 100 stops producing water for too long (such as more than twenty minutes), the water production system 100 can open the first control valve 51 and the third control valve 41 before starting to produce water, and control the variable frequency water pump to start working, so that the stale water on the outlet side of the reverse osmosis filter element 53 flows back to the inlet side of the reverse osmosis filter element 53, and the stale water circulates through the reverse osmosis filter element 53 for many times until the outlet side of the reverse osmosis filter element 53 is filled with pure water. At this time, the water production system 100 can close the third control valve 41 and open the second control valve 21 to start water production.

[0100] During the water production process of the water production system 100, the first mineral detection component 11 can detect the mineral concentration of pure water. The water production system 100 can adjust the power of the variable frequency water pump according to the mineral concentration of pure water detected by the first mineral detection component 11. For example, the water production system 100 can increase the power of the variable frequency water pump to increase the flow rate and flow of water, thereby reducing the contact time between pure water and the mineralized filter element 54 to reduce the mineral concentration of pure water.

[0101] Alternatively, the water production system 100 can lower the power of the variable frequency water pump to lower the water flow rate and flow rate, thereby increasing the contact time between the pure water and the mineralized filter element 54 to increase the mineral concentration of the pure water. In this way, the mineral concentration of the pure water can be regulated, and it is beneficial to maintain the mineral concentration of the pure water at a stable level, which can improve the user's water use experience.
