For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Next, reference is made to Figures 1 - 3 Describe a water production device 1000 according to an embodiment of the present invention.

[0034] As Figures 1 - 3 shown, a water production device 1000 according to an embodiment of the present invention includes: a body 100, a pre-filter element 52, a reverse osmosis filter element 53, a mineralization filter element 54, and a first mineral detection element 11. The body 100 may have a water inlet 400 and a first water outlet 200. The water inlet 400 may be connected to a water source (such as a reservoir, a water pipe) to facilitate connecting unpurified water to the water production device 1000, and the purified water produced by the water production device 1000 can flow out through the first water outlet 200 for the convenience of users.

[0035] The pre-filter 52 can be arranged inside the machine body 100, and the inlet of the pre-filter 52 can be communicated with the water inlet 400. The reverse osmosis filter 53 can be arranged inside the machine body 100, and the inlet of the reverse osmosis filter 53 can be communicated with the outlet of the pre-filter 52. The pre-filter 52 can perform primary filtration on water, which can reduce the filtration pressure of the reverse osmosis filter 53 and is beneficial to improving the service life of the reverse osmosis filter 53. For example, the pre-filter 52 can be composed of polypropylene fiber cotton (PP cotton) and activated carbon, or the pre-filter 52 can be polypropylene fiber composite activated carbon (PP composite activated carbon). The reverse osmosis filter 53 can be an RO membrane reverse osmosis filter, which can improve the filtration accuracy of water and the filtration effect of water.

[0036] The mineralization filter 54 can be arranged inside the machine body 100, and the mineralization filter 54 can be arranged adjacent to the pre-filter 52, so that multiple filters inside the machine body 100 can be integrated together, which is beneficial to saving the internal space of the machine body 100 and is beneficial to the miniaturization of the water treatment device 1000. Thus, on the basis of ensuring the normal use of each function of the water treatment device 1000, that is, on the basis of ensuring the perfection of multiple functions of the water treatment device 1000, the floor area of the water treatment device 1000 can be reduced, which is convenient for installation. The mineralization filter 54 can be a mineral carbon rod filter, which can ensure full contact between the purified water and the mineralization filter 54.

[0037] For example, the mineralization filter 54 can be connected to the pre-filter 52 through fasteners, or the mineralization filter 54 and the pre-filter 52 can be installed on the same bracket, and the mineralization filter 54 and the pre-filter 52 can be respectively connected to the bracket through fasteners, which can improve the connection stability between the mineralization filter 54 and the pre-filter 52, reduce the probability of multiple filters inside the water treatment device 1000 falling off due to the vibration of the water treatment device 1000, and improve the reliability of the water treatment device 1000. Of course, the mineralization filter 54 can be clamped to the pre-filter 52, or the mineralization filter 54 and the pre-filter 52 can be respectively clamped to the same bracket, which is convenient for disassembly and maintenance.

[0038] Among them, the mineralized water inlet of the mineralization filter 54 can be communicated with the pure water outlet of the reverse osmosis filter 53, so that the purified water filtered by the pre-filter 52 and the reverse osmosis filter 53 can flow through the mineralization filter 54, and the mineralization filter 54 can add minerals beneficial to the human body (such as calcium, magnesium, strontium, zinc or bicarbonate, etc.) to the purified water. The mineralized water outlet of the mineralization filter 54 can be communicated with the first water outlet 200, so that the purified 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.

[0039] Thus, the water in the water treatment device 1000 can flow through the pre-filter element 52 and the reverse osmosis filter element 53 in sequence from the water inlet 400 to become purified water. The purified water can flow through the mineralization filter element 54 to become purified water added with minerals beneficial to the human body, and flow out through the first water outlet 200, which can ensure the water purification effect and the concentration of minerals beneficial to the human body in the purified water, thereby ensuring the user's water use safety and the user's mineral intake, enabling the user to have a normal metabolic level and normal physiological functions.

[0040] The first mineral detection element 11 can be arranged between the mineralized water outlet of the mineralization filter element 54 and the first water outlet 200, and the first mineral detection element 11 can detect the mineral concentration of the purified water, so that the water treatment device 1000 can adjust the mineral concentration of the purified water produced subsequently by the water treatment device 1000 according to the mineral concentration detected by the first mineral detection element 11, and it is convenient for the water treatment device 1000 to adjust the mineral concentration of the purified water according to the user's selection, thereby facilitating maintaining the mineral concentration of the purified water at a stable level and improving the user's water use experience.

[0041] The first mineral detection element 11 can be a total dissolved solids sensor (TDS sensor). The TDS sensor can calculate the TDS value of water by measuring the conductivity of water. For example, when the 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 substances contained in water, which can reflect the hardness and salt content of water quality. If the TDS value of water is higher, the water quality is harder and the salt content of the water is higher; on the contrary, if the TDS value of water is lower, the water quality is softer and the salt content of the water is less.

[0042] According to the water treatment device 1000 of the embodiment of the present invention, by arranging the mineralization filter element 54 behind the pre-filter element 52 and the reverse osmosis filter element 53, the water treatment device 1000 can add minerals beneficial to the human body to the filtered purified water, ensure the water purification effect, and ensure the concentration of minerals beneficial to the human body in the purified water, thereby ensuring the user's water use safety and the user's mineral intake, enabling the user to have a normal metabolic level and normal physiological functions.

[0043] And by arranging the mineralization filter element 54 adjacent to the pre-filter element 52, multiple filter elements in the machine body 100 can be integrated together, which is beneficial to saving the internal space of the machine body 100 and conducive to the miniaturization of the water purification device 1000. Thus, on the basis of ensuring the perfection of multiple functions of the water purification device 1000, the floor area of the water purification device 1000 can be reduced, facilitating installation, and at the same time, the user experience can be improved.

[0044] In addition, by arranging the first mineral detection element 11 behind the mineralization filter element 54, the detection of the mineral concentration of pure water can be realized, so that the water purification device 1000 can adjust the mineral concentration of pure water according to the mineral concentration detected by the first mineral detection element 11. Thus, it is beneficial to maintain the mineral concentration of pure water at a stable level and improve the user's water use experience.

[0045] As Figure 1 and Figure 3 shown, according to some embodiments of the present invention, the machine body 100 may further have a second water outlet 300, and the second water outlet 300 may be communicated with the mineralized water outlet of the mineralization filter element 54, so that the pure water added with minerals beneficial to the human body can flow out through the second water outlet 300. The second water outlet 300 may be communicated with the indoor water connection port 500 (such as the water outlet of the faucet 80), so that the pure water at the second water outlet 300 can flow out through the indoor water connection port 500, facilitating user use.

[0046] As Figure 3 shown, according to some embodiments of the present invention, the water inlet 400 may be communicated with the indoor water inlet 600 (such as a water pipe). That is, the user can cut off the water pipe to divide it into a water supply branch 70 and a faucet 80. The water supply branch 70 may be communicated with a water source (such as tap water), and the water outlet of the faucet 80 may be the indoor water connection port 500. Among them, the water inlet 400 of the machine body 100 may be communicated with the water supply branch 70, and the second water outlet 300 of the machine body 100 may be communicated with the faucet 80. Thus, it is beneficial for the water purification device 1000 to directly provide pure water added with minerals beneficial to the human body to the user through the faucet 80.

[0047] It can be understood that the water supply branch 70 may be provided with a water inlet valve 57. 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 tap water from flowing out, which is convenient for the installation of the water treatment device 1000 and helps reduce water waste during the installation of the water treatment device 1000. Further, after the installation of the water treatment device 1000 is completed, the user can open the water inlet valve 57 to connect the water treatment device 1000 to the water source, ensuring the normal operation of the water treatment device 1000. Thus, the user can manually turn off the water inlet function of the water treatment device 1000, allowing the operator to open the water inlet valve 57 after confirming the completion of the installation of the water treatment device 1000 to restore the water inlet function of the water treatment device 1000, ensuring the feasibility of the installation of the water treatment device 1000.

[0048] As Figure 2 and Figure 3 shown, in some embodiments, the water treatment device 1000 may further include a water storage tank 58. The water storage tank 58 may be disposed between the mineralized water outlet of the mineralization filter element 54 and the first water outlet 200, such that the purified water added with minerals beneficial to the human body can flow out through the first water outlet 200 after flowing through the water storage tank 58. That is, the water storage tank 58 can store the purified water added with minerals, ensuring the amount of purified water used by the user each time and reducing the water treatment duration of the water treatment device 1000. Thus, it can ensure that the water used by the user is available immediately when needed, facilitating the user's use, and at the same time reducing the water treatment frequency of the water treatment device 1000, which is beneficial to extending the service life of the water treatment device 1000.

[0049] As Figure 2 and Figure 3 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 mineralization 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 mineralization 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 mineralization filter element 54 can be connected to the water storage tank 58, facilitating the water storage tank 58 to store the purified water added with minerals and facilitating the user's use.

[0050] The water production device 1000 may further include a third mineralization water path 30. The third mineralization water path 30 may be connected between the first mineralization water path 10 and the second water outlet 300. That is, one end of the third mineralization water path 30 may communicate with the other end of the first mineralization water path 10, and the other end of the third mineralization water path 30 may communicate with the second water outlet 300, so that the mineralized water outlet of the mineralization filter element 54 can communicate with the second water outlet 300, facilitating the purified water added with minerals to flow out successively through the second water outlet 300 and the indoor water connection port 500 (such as the water outlet of the faucet 80), which is convenient for users to use.

[0051] The first mineral detection component 11 is arranged on the first mineralization water path 10. Alternatively, the first mineral detection component 11 may be arranged on the second mineralization water path 20. That is, the first mineral detection component 11 may be arranged at the rear end of the mineralization filter element 54, which can realize the detection of the mineral concentration of the purified water added with minerals beneficial to the human body, so that the water production device 1000 can adjust the mineral concentration of the purified water according to the mineral concentration detected by the first mineral detection component 11, which is beneficial to maintaining the mineral concentration of the purified water at a stable level and can improve the user's water use experience.

[0052] It can be understood that the first mineral detection component 11 may be arranged on the first mineralization water path 10, so that the first mineral detection component 11 can accurately detect the mineral concentration of the purified water in the first mineralization water path 10, so that the water production device 1000 can adjust the mineral concentration of the purified water in the second mineralization water path 20 and the mineral concentration of the purified water in the third mineralization water path 30 according to the mineral concentration of the purified water in the first mineralization water path 10. That is, the water production device 1000 can adjust the mineral concentration of the purified water at the first water outlet 200 and the second water outlet 300 together, which is beneficial to reducing the number of the first mineral detection components 11, saving costs and being convenient for operation.

[0053] Of course, the first mineral detection component 11 may be arranged on the second mineralization water path 20, so that the first mineral detection component 11 can accurately detect the mineral concentration of the purified water in the second mineralization water path 20, so that the water production device 1000 can adjust the mineral concentration of the purified water according to the mineral concentration of the purified water in the second mineralization water path 20. That is, the water production device 1000 can adjust the mineral concentration of the purified water at the first water outlet 200, and can improve the accuracy of adjusting the mineral concentration of the purified water at the first water outlet 200, which can improve the user's water use experience.

[0054] Of course, the first mineral detection component 11 can also be arranged on the third mineralization water path 30, so that the first mineral detection component 11 can accurately detect the mineral concentration of the purified water in the third mineralization water path 30, so that the water purification device 1000 can adjust the mineral concentration of the purified water according to the mineral concentration of the purified water in the third mineralization water path 30, that is, the water purification device 1000 can adjust the mineral concentration of the purified water at the second water outlet 300, and can improve the accuracy of adjusting the mineral concentration of the purified water at the second water outlet 300, and can improve the user's water use experience.

[0055] As Figure 3 shown, in some embodiments, a first driving component 55 can be arranged between the pre-filter element 52 and the reverse osmosis filter element 53. The first driving component 55 can drive water to flow from the water inlet 400 to the first water outlet 200, so that the water in the water purification device 1000 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 can ensure the mineral concentration of the purified water beneficial to the human body, thus ensuring the user's water use safety and ensuring the user's mineral intake, so that the user can have a normal metabolic level and normal physiological functions.

[0056] Among them, the first mineral detection component 11 can detect the mineral concentration of the purified water. The water purification device 1000 can adjust the power of the first driving component 55 according to the user's selection, and the water purification device 1000 can also 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 purification device 1000 can adjust the water flow rate and flow volume to control the contact time of the purified water with the mineralization filter element 54, so as to realize the adjustment of the mineral concentration of the purified water, and is beneficial to maintaining the mineral concentration of the purified water at a stable level, and 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 to facilitate the water purification device 1000 to adjust the power of the first driving component 55 (such as the rotation speed of the variable frequency water pump).

[0057] Specifically, the water purification device 1000 can increase the power of the first driving component 55 according to the user's selection (such as the user wants to drink purified water with a higher mineral concentration beneficial to the human body) to increase the water flow rate and flow volume, so as to reduce the contact time of the purified water with the mineralization filter element 54 and reduce the mineral concentration of the purified water; or, the water purification device 1000 can decrease the power of the first driving component 55 according to the user's selection (such as the user wants to drink purified water with a lower mineral concentration beneficial to the human body) to decrease the water flow rate and flow volume, so as to increase the contact time of the purified water with the mineralization filter element 54 and increase the mineral concentration of the purified water.

[0058] Of course, the water production device 1000 can automatically increase the power of the first driving member 55 according to the mineral concentration detected by the first mineral detection member 11 (such as when the mineral concentration detected by the first mineral detection member 11 is too high), so as to increase the water flow rate and flow, thereby reducing the contact time between the purified water and the mineralization filter element 54, and automatically reducing the mineral concentration of the purified water; or, the water production device 1000 can automatically decrease the power of the first driving member 55 according to the mineral concentration detected by the first mineral detection member 11 (such as when the mineral concentration detected by the first mineral detection member 11 is too low), so as to decrease the water flow rate and flow, thereby increasing the contact time between the purified water and the mineralization filter element 54, and automatically increasing the mineral concentration of the purified water.

[0059] According to some embodiments of the present invention, after the water production device 1000 stops producing water, the water production device 1000 can automatically record the user's water consumption until the water production device 1000 starts producing water again. If the user's water consumption is less than the water storage capacity (such as volume or capacity) of the mineralization filter element 54, the contact time between the purified water in the mineralization filter element 54 and the mineralization filter element 54 is too long, resulting in a relatively high mineral concentration in the water produced after the water production device 1000 starts producing water again. If the user's water consumption is greater than the water storage capacity of the mineralization filter element 54, the contact time between the purified water in the mineralization filter element 54 and the mineralization filter element 54 is too short, resulting in a relatively low mineral concentration in the water produced after the water production device 1000 starts producing water again.

[0060] Among them, when the water production device 1000 starts producing water again, the water production device 1000 can adjust the power of the first driving member 55 according to the user's water consumption and the water storage capacity of the mineralization filter element 54. If the user's water consumption is less than the water storage capacity of the mineralization filter element 54, the water production device 1000 can increase the power of the first driving member 55 to increase the water flow rate and flow, thereby reducing the contact time between the purified water and the mineralization filter element 54 to reduce the mineral concentration of the purified water.

[0061] If the user's water consumption is greater than the water storage capacity of the mineralization filter element 54, the water production device 1000 can decrease the power of the first driving member 55 to decrease the water flow rate and flow, thereby increasing the contact time between the purified water and the mineralization filter element 54 to increase the mineral concentration of the purified water. Thus, the mineral concentration of the purified water can be maintained at a stable level, improving the user's water use experience.

[0062] Such as Figure 3 As shown, in some embodiments, the water production device 1000 can have a water pressure switch 12. A first control valve 51 can be provided between the pre-filter 52 and the water inlet 400. The opening and closing of the first control valve 51 can control the on-off of the water path between the pre-filter 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 driving member 55) by receiving a low-pressure signal.

[0063] That is, when the first water outlet 200 is in communication with the outside world, the water pressure of the purified water in the second mineralization water path 20 can be lowered, so that the water pressure switch 12 can receive a low-pressure signal and automatically turn on to control the first driving member 55 to operate and open the first control valve 51, which is beneficial to realizing the automatic water production of the water production device 1000, facilitating operation. And when the second water outlet 300 is in communication with the outside world, the water pressure of the purified water in the third mineralization water path 30 can be lowered, so that the water pressure switch 12 can receive a low-pressure signal and automatically turn on to control the first driving member 55 to operate and open the first control valve 51, which is beneficial to realizing the automatic water production of the water production device 1000, facilitating operation.

[0064] Such as Figure 3 As shown, in some embodiments, the first mineralization water path 10 may be provided with a one-way valve 56, which can control the one-way flow of the purified water in the first mineralization water path 10, and can prevent the purified water added with minerals beneficial to the human body from flowing back into the mineralization filter element 54, which is beneficial to improving the water production effect of the water production device 1000 and is also beneficial to extending the service life of the water production device 1000. The one-way valve 56 may 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 receiving the low-pressure signal, facilitate the automatic water production of the water production device 1000, and can improve the user experience.

[0065] Wherein, the first mineralization water path 10 may be provided with a first mineral detection member 11. The first mineral detection member 11 may be arranged between the one-way valve 56 and the mineralized water outlet, or the first mineral detection member 11 may be arranged between the one-way valve 56 and the water pressure switch 12, or the first mineral detection member 11 may be arranged between the water pressure switch 12 and the second mineralization water path 20, which is convenient for layout.

[0066] Meanwhile, the detection of the mineral concentration of the purified water in the first mineralization water path 10 can be realized, so that the water production device 1000 can adjust the mineral concentration of the purified water in the second mineralization water path 20 and the mineral concentration of the purified water in the third mineralization water path 30 according to the mineral concentration of the purified water in the first mineralization water path 10, that is, the water production device 1000 can adjust the mineral concentration of the purified water at the first water outlet 200 and the second water outlet 300 together, which is beneficial to reducing the number of the first mineral detection members 11 and saving costs.

[0067] Such as Figure 3As shown, in some embodiments, a second control valve 21 may be provided between the mineralized water outlet of the mineralization filter element 54 and the water storage 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 storage tank 58, so that the purified water added with minerals beneficial to the human body can flow into the water storage tank 58. That is, the water storage tank 58 can store the purified water added with minerals, and the purified water in the water storage tank 58 can flow out through the first water outlet 200, which can ensure the amount of purified water used by the user each time and can ensure that the water used by the user is available immediately when needed, facilitating the user's use.

[0068] As Figure 3 shown, in some embodiments, a faucet 80 may be connected to the second water outlet 300. The indoor water connection port 500 may be the outlet of the faucet 80, and the indoor water connection port 500 may communicate with the outside to reduce the water pressure at the second water outlet 300. Thus, the water pressure switch 12 can receive a low-pressure signal to automatically turn on when the indoor water connection port 500 is opened, so as to control the first driving member 55 to work and open the first control valve 51, and the automatic water production of the water production device 1000 can be realized.

[0069] And the water pressure switch 12 can receive a high-pressure signal to automatically turn off when the indoor water connection port 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 connection port 500 is opened, so that the water production device 1000 can directly discharge the purified water added with minerals beneficial to the human body to the outside through the indoor water connection port 500, and the water pressure switch 12 can automatically close when the indoor water connection port 500 is closed, so that the water production device 1000 stops working, thereby ensuring that the water used by the user is available immediately when needed and facilitating operation.

[0070] Of course, the second control valve 21 can be opened to connect the water path between the mineralization filter element 54 and the water storage tank 58. Thus, the water pressure switch 12 can receive a low-pressure signal to automatically turn on when the second control valve 21 is opened, so as to control the first driving member 55 to work and open the first control valve 51, and the automatic water production of the water production device 1000 can be realized. And the water pressure switch 12 can receive a high-pressure signal to automatically turn off when the second control valve 21 is closed, so as to control the first driving member 55 to stop working and close the first control valve 51.

[0071] That is, the water pressure switch 12 can automatically open when the second control valve 21 is opened, so that the water storage tank 58 stores the purified water added with minerals beneficial to the human body, facilitating the user's subsequent water use. Or, the water production device 1000 can directly discharge the purified water added with minerals beneficial to the human body to the outside through the first water outlet 200, which can ensure that the water used by the user is available immediately when needed, can improve the user's water use experience, and the water pressure switch 12 can automatically close when the second control valve 21 is closed, so that the water production device 1000 stops working, facilitating operation.

[0072] As Figure 3 shown, in some embodiments, the second control valve 21 can be automatically opened when the water level in the water storage tank 58 is lower than the preset water level. That is, when the remaining water volume in the water storage tank 58 is small, the second control valve 21 can be automatically opened to enable the water pressure switch 12 to be automatically turned on, so that the first driving member 55 can be controlled to operate and the first control valve 51 can be opened, realizing automatic water production of the water production device 1000, and enabling the water storage tank 58 to be automatically replenished with water, which can improve the user experience.

[0073] Of course, the second control valve 21 can be automatically opened when the water level change amount in the water storage tank 58 is greater than the preset water level change amount (such as six hundred milliliters). That is, when the user uses too much water, the second control valve 21 can be automatically opened to enable the water pressure switch 12 to be automatically turned on, so that the water production device 1000 can control the first driving member 55 to operate and the first control valve 51 can be opened, realizing automatic water production of the water production device 1000, and enabling the water storage tank 58 to be automatically replenished with water, which can improve the user experience.

[0074] As Figure 3 shown, according to some embodiments of the present invention, the water production device 1000 may further include a waste water branch 60. One end of the waste water branch 60 can be communicated with the reverse osmosis filter element 53, and the other end of the waste water branch 60 can be communicated with the outside. The reverse osmosis filter element 53 may have a reverse osmosis membrane (RO membrane). The reverse osmosis membrane can allow water molecules to pass through, and the reverse osmosis membrane can block impurities such as minerals (including minerals harmful to the human body), heavy metals, bacteria, viruses, and organic substances. The first driving member 55 can drive the water to flow, so that the water molecules pass through the reverse osmosis membrane against the concentration gradient to form pure water.

[0075] Among them, the water that does not pass through the reverse osmosis membrane will become concentrated water (waste water) due to the increase in impurity concentration. The waste water branch 60 can discharge the waste water, preventing the surface of the reverse osmosis membrane from being blocked, and the waste water can continuously flow on the surface of the reverse osmosis membrane to wash the reverse osmosis membrane, ensuring the permeability of 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. The waste water branch 60 may have a waste water valve 61, and the opening and closing of the waste water valve 61 can control the on-off of the waste water branch 60. The water production device 1000 can open the waste water valve 61 during water production to enable the waste water branch 60 to discharge the waste water, ensuring the normal operation of the reverse osmosis filter element 53 and the water production effect of the water production device 1000.

[0076] As Figure 3As shown, in some embodiments, the water production device 1000 may further include a return water branch 40. 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 water 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 water outlet side of the reverse osmosis filter element 53 is pure water, and the minerals contained in the water (such as tap water) can be retained on the water inlet side of the reverse osmosis filter element 53.

[0077] However, after the water production device 1000 stops producing water, the minerals on the water inlet side of the reverse osmosis filter element 53 will penetrate through the reverse osmosis membrane into the pure water on the water outlet side of the reverse osmosis filter element 53, 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 in a state of not flowing for a long time. Therefore, if the water production device 1000 resumes water production after stopping, 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 stable mineral concentration of the pure water produced by the water production device 1000 and difficult to ensure the water use safety of users.

[0078] Among them, the return water branch 40 may be provided with a third control valve 41. The opening and closing of the third control valve 41 can control the on-off of the return water branch 40. Thus, the first control valve 51 and the third control valve 41 can be opened and the first driving 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, realizing multiple filtration of the stale water.

[0079] Thus, when the water production device 1000 resumes water production, it can prevent the stale water mixed with the above-mentioned minerals (including minerals harmful to the human body) from flowing through the mineralization filter element 54, thereby ensuring the stable mineral concentration of the pure water added with minerals beneficial to the human body produced by the water production device 1000. It should be noted that the return water branch 40 may be provided with a one-way valve 56, which can control the one-way circulation of water in the return water branch 40, improve the filtration effect of the stale water, and ensure the water use safety of users.

[0080] Such as Figure 3As shown, in some embodiments, when the closing duration of the water pressure switch 12 is greater than a preset duration (such as twenty minutes), that is, when the water production stop duration of the water production device 1000 is greater than the preset duration, the water production device 1000 can automatically open the third control valve 41 before starting water production, so that the first driving member 55 can drive water (such as tap water and stale water) to circulate in the return water branch 40 until the water outlet side of the reverse osmosis filter element 53 is filled with pure water. At this time, the water production device 1000 can close the third control valve 41 and start water production, which can prevent the stale water mixed with the above-mentioned minerals (including minerals harmful to the human body) from flowing through the mineralization filter element 54, thereby ensuring the stable mineral concentration of the pure water with beneficial minerals added produced by the water production device 1000 and ensuring the water use safety of users.

[0081] It can be understood that the reverse osmosis filter element 53 can circularly filter the stale water to make the water outlet side of the reverse osmosis filter element 53 filled with pure water. And since the water that has not passed through the reverse osmosis membrane will become concentrated water (waste water) on the water inlet side of the reverse osmosis filter element 53 due to the increase in impurity concentration, the water production device 1000 can open the waste water valve 61 when the third control valve 41 is opened, so that the waste water branch 60 discharges the waste water, which can prevent the surface of the reverse osmosis membrane from being blocked, and the waste water can continuously flow on the surface of the reverse osmosis membrane to wash the reverse osmosis membrane, thereby ensuring the filtration efficiency of the reverse osmosis filter element 53 and improving the service life of the reverse osmosis filter element 53.

[0082] 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 to open and close the water inlet valve 57, thereby improving the feasibility of installing the water inlet device. The first control valve 51 can be an electric valve, which can realize the automatic control of the water inlet of the water inlet device. The second control valve 21 can be an electric valve, which can realize the automatic control of the on-off of the second mineralization water path 20 of the water inlet device. The third control valve 41 can be an electric valve, which can realize the automatic control of the on-off of the return water branch 40 of the water inlet device. The waste water valve 61 can be an electric valve, which can realize the automatic control of the on-off of the waste water branch 60 of the water inlet device, which is convenient for operation and is beneficial to improving the user experience.

[0083] The following refers to Figure 1 、 Figure 2 and Figure 3To describe a specific embodiment of the present application, the water purification device 1000 may include a machine body 100, a first mineralization water path 10, a second mineralization water path 20, a return water branch 40, a pre-filter 52, a reverse osmosis filter 53, a mineralization filter 54, a variable frequency water pump, and a water storage tank 58. The machine body 100 may have a first water outlet 200 and a water inlet 400. The inlet of the pre-filter 52 may be communicated with the water inlet 400. The inlet of the reverse osmosis filter 53 may be communicated with the outlet of the pre-filter 52. The mineralized water inlet of the mineralization filter 54 may be communicated with the pure water outlet of the reverse osmosis filter 53.

[0084] The mineralized water outlet of the mineralization filter 54 may be communicated with one end of the first mineralization water path 10. The other end of the first mineralization water path 10 may be communicated with one end of the second mineralization water path 20. The other end of the second mineralization water path 20 may be communicated with the water storage tank 58. The water storage tank 58 may be communicated with the first water outlet 200. The pure water outlet of the reverse osmosis filter 53 may be connected to the inlet of the reverse osmosis filter 53 through the return water branch 40.

[0085] Wherein, a first control valve 51 may be provided between the pre-filter 52 and the water inlet 400. A variable frequency water pump may be arranged in the water path between the water inlet 400 and the reverse osmosis filter 53. The first mineralization water path 10 may be provided with a first mineral detection element 11 and a water pressure switch 12. The second mineralization water path 20 may be provided with a second control valve 21. The return water branch 40 may be provided with a third control valve 41.

[0086] The water purification device 1000 may start to produce water. That is, the water purification device 1000 may 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 a low-pressure signal, and controls the variable frequency water pump to start working. Tap water may flow through the pre-filter 52 and the reverse osmosis filter 53 in sequence to become pure water. The pure water may flow through the mineralization filter 54 to become pure water added with minerals beneficial to the human body. Thus, the water storage tank 58 may store pure water added with minerals beneficial to the human body, and the pure water added with minerals beneficial to the human body may flow out from the first water outlet 200.

[0087] Of course, if the water production stop time of the water purification device 1000 is too long (such as more than twenty minutes), the water purification device 1000 may 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 water outlet side of the reverse osmosis filter 53 flows back to the water inlet side of the reverse osmosis filter 53, and the stale water flows through the reverse osmosis filter 53 in multiple cycles until the water outlet side of the reverse osmosis filter 53 is filled with pure water. At this time, the water purification device 1000 may close the third control valve 41 and open the second control valve 21 to start producing water.

[0088] During the water production process of the water production device 1000, the first mineral detection component 11 can detect the mineral concentration of pure water. The water production device 1000 can adjust the power of the variable frequency water pump according to the mineral concentration of the pure water detected by the first mineral detection component 11. For example, the water production device 1000 can increase the power of the variable frequency water pump to increase the water flow rate and flow, so as to reduce the contact time between the pure water and the mineralization filter element 54, thereby reducing the mineral concentration of the pure water.

[0089] Alternatively, the water production device 1000 can reduce the power of the variable frequency water pump to reduce the water flow rate and flow, so as to increase the contact time between the pure water and the mineralization filter element 54, thereby increasing the mineral concentration of the pure water. Thus, the adjustment of the mineral concentration of the pure water can be achieved, which is beneficial to maintaining the mineral concentration of the pure water at a stable level and improving the user's water use experience.
