[0029] Water purification equipment uses reverse osmosis membrane filtration technology, which filters out all substances in the water. Pure water without any beneficial elements is, in a sense, not healthy water and does not conform to the latest concept of healthy water. Therefore, products that mineralize purified water using mineralization filter cartridges have emerged. However, in these technologies, the mineral content in the water may be too high or below standard, thus affecting the widespread use of these products.

[0030] In view of this, the present invention provides a filter element structure and a mineral water purifier, which can effectively prevent the mineral content in the water from being too high or below standard by changing the immersion volume of the mineral filter material.

[0031] like Figure 1 As shown, the filter element structure 100 provided in this embodiment of the present invention includes a housing 10 and a first mineralized filter material 20. The housing 10 is provided with a receiving cavity 11, an inlet 12, and an outlet 13. The first mineralized filter material 20 is disposed in the receiving cavity 11 and connects the inlet 12 and the outlet 13. By providing the first mineralized filter material 20, when the first mineralized filter material 20 is immersed in water, it can release (dissolve) minerals into the water, thereby making the water flowing through the filter element structure 100 contain minerals.

[0032] When in use, water flows into the housing 10 through the inlet 12, and after being treated by the first mineralized filter material 20, it flows out from the outlet 13. The water that flows out contains minerals.

[0033] Please see Figure 1 and Figure 2 The outer casing 10 is also provided with an air inlet 14 for connecting to the air pressure regulating device 402. The air inlet 14 is connected to the accommodating cavity 11 to adjust the air pressure in the accommodating cavity 11, thereby changing the liquid level (i.e., water level) in the accommodating cavity 11. By setting the air inlet 14, gas can enter and exit the accommodating cavity 11 through the air inlet 14 to adjust the air pressure in the accommodating cavity 11, which can change the liquid level in the accommodating cavity 11. This changes the height of the first mineralized filter material 20 immersed in the water (i.e., changes the volume of the first mineralized filter material 20 immersed in the water), thereby changing the amount of minerals released by the first mineralized filter material 20. In this way, it can prevent the mineral content in the water from being too high or below standard.

[0034] Therefore, the filter element structure 100 provided in this embodiment can effectively prevent the mineral content in the water from being too high or below standard by changing the volume of the first mineralized filter material 20 immersed in the water.

[0035] In specific implementation, when the filter element structure 100 is in an soaking state, for example, if the water flow rate is too slow, water flow stops, or the water flow stops for a set period of time, the mineral content in the water may be too high. In this case, gas can be supplied into the receiving cavity 11 through the air inlet 14 to increase the air pressure in the receiving cavity 11, thereby lowering the water level in the receiving cavity 11, reducing the volume of the first mineralized filter material 20 immersed in the water, and reducing the release of minerals. In this embodiment, the soaking state refers to a situation where the flow rate in the filter element structure 100 is less than the design threshold, including situations where the water flow stops or the flow rate is slow.

[0036] When the flow rate of water flowing through the filter structure 100 exceeds the set flow rate (i.e., the water flow rate is high), it may cause the mineral content in the water to be substandard. At this time, the gas in the containment chamber 11 can be discharged through the air inlet 14, the air pressure in the containment chamber 11 decreases, thereby increasing the water level in the containment chamber 11, increasing the volume of the first mineralized filter material 20 immersed in the water, and thus increasing the release of minerals.

[0037] Please see Figure 1 The filter element structure 100 also includes a second filter material 30, which is disposed within the receiving cavity 11. The vertical direction is defined by the direction of liquid level rise and fall within the filter element structure 100, and the second filter material 30 is located below the first mineralized filter material 20. It is understood that in other embodiments, the filter element structure 100 may not include the second filter material 30.

[0038] In one embodiment, the second filter material 30 is a non-mineralized filter material, meaning that the second filter material 30 does not release minerals. In specific applications, the second filter material 30 can be used to purify water or adjust the pH value of water, etc. Of course, in other embodiments, the second filter material 30 can also be a mineralized filter material. In specific applications, the minerals released by the second filter material 30 can be the same as those released by the first mineralized filter material 20, or they can be different from those released by the first mineralized filter material 20.

[0039] In one embodiment, the first mineralized filter material 20 and the second filter material 30 may be integrally disposed or separately disposed within the outer shell 10, and the second filter material 30 may be encapsulated within the inner shell.

[0040] In one embodiment, the filter element structure 100 is provided with parallel water channels for water to flow through the first mineralizing filter material 20 and the second filter material 30 respectively. Thus, the first mineralizing filter material 20 and the second filter material 30 are arranged in parallel; a portion of the water enters the housing 10 and is treated by the first mineralizing filter material 20, while another portion enters the housing 10 and is treated by the second filter material 30. In practical applications, the water treated by the first mineralizing filter material 20 and the water treated by the second filter material 30 can be discharged from the housing 10 simultaneously, or they can be discharged from the housing 10 separately.

[0041] Please see Figure 1 The outer casing 10 includes a bottom wall 15, a top wall 16, and a side wall 17. The bottom wall 15 and the top wall 16 are arranged opposite to each other. The side wall 17 is connected between the bottom wall 15 and the top wall 16 and forms a receiving cavity 11 with the bottom wall 15 and the top wall 16. The first mineralized filter material 20 and the second filter material 30 are stacked and received in the receiving cavity 11. The first mineralized filter material 20 is arranged near the top wall 16 and the second filter material 30 is arranged near the bottom wall 15.

[0042] The first mineralizing filter media 20 and the second filter media 30 are both spaced apart from the sidewall 17. The gap between the first mineralizing filter media 20 and the sidewall 17 forms a first water inlet channel 41, and the gap between the second filter media 30 and the sidewall 17 forms a second water inlet channel 42. The first water inlet channel 41 and the second water inlet channel 42 are connected. The first mineralizing filter media 20 has a first water outlet channel 51 inside, and the second filter media 30 has a second water outlet channel 52 inside. The first water outlet channel 51 and the second water outlet channel 52 are connected. The bottom wall 15 has a water inlet 12 and a water outlet 13. The water inlet 12 is connected to the second water inlet channel 42, and the water outlet 13 is connected to the second water outlet channel 52.

[0043] In use, water flows from inlet 12 into the second inlet channel 42. A portion of the water flows into the second filter media 30, is treated by the second filter media 30, and then flows into the second outlet channel 52, before being discharged through outlet 13. The other portion of the water flows from the second inlet channel 42 into the first inlet channel 41, then into the first mineralizing filter media 20, is treated by the first mineralizing filter media 20, flows into the first outlet channel 51, and then flows through the second outlet channel 52 before being discharged through outlet 13. This forms a parallel water path through the first mineralizing filter media 20 and the second filter media 30.

[0044] In one embodiment, the air vent 14 is located on the top wall 16. The water body is located at the lower part of the accommodating cavity 11 under the influence of gravity. Positioning the air vent 14 on the top wall 16 prevents water from being discharged through the air vent 14. Specifically, the air vent 14 is connected to the first water inlet channel 41. It is understood that in other embodiments, the air vent 14 may also be located on the side wall 17 near the end of the top wall 16.

[0045] Please see Figure 1The filter element structure 100 also includes a water level monitor 60, which is located inside the receiving cavity 11 and is used to detect the water level inside the receiving cavity 11, i.e., to detect the liquid level inside the receiving cavity 11. In specific implementation, the water level inside the receiving cavity 11 can be used to determine whether it is necessary to adjust the height of the first mineralized filter material 20 immersed in the water. For example, when the water level monitor 60 detects that the water level inside the receiving cavity 11 exceeds or falls below a preset value, in order to prevent the water level from being too high or too low, resulting in insufficient or excessive mineral content in the water, it can be determined that the water level inside the receiving cavity 11 needs to be adjusted.

[0046] In one embodiment, the water level monitor 60 is a water level probe. Of course, the water level monitor 60 can also be other water level detection devices, such as a liquid level sensor.

[0047] In one embodiment, the filter element structure 100 further includes an exhaust valve (not shown), which is used to discharge gas from the accommodating cavity 11. Specifically, the exhaust valve can be installed at the air inlet 14. When gas needs to be input into the accommodating cavity 11, the exhaust valve is closed; when gas needs to be discharged from the accommodating cavity 11, the exhaust valve is opened. Alternatively, a mounting hole for installing the exhaust valve can be provided on the housing 10. When gas needs to be input into the accommodating cavity 11, the pressure regulating device 402 is activated to input gas through the air inlet 14; when gas needs to be discharged from the accommodating cavity 11, the pressure regulating device 402 can be closed, and the exhaust valve can be opened to allow the gas in the accommodating cavity 11 to be discharged through the exhaust valve.

[0048] Please see Figure 2 This utility model embodiment also provides a mineral water purifier, including an inlet pipe 200, an outlet pipe 300, an air guide pipe 400 and the above-mentioned filter structure 100. The inlet pipe 200 is connected to the inlet 12, the outlet pipe 300 is connected to the outlet 13, and the air guide pipe 400 is connected to the air guide port 14.

[0049] When in use, water can be input into the filter structure 100 through the inlet pipe 200. When the water flows through the filter structure 100, the first mineralized filter material 20 releases minerals into the water. The water containing minerals is discharged through the outlet pipe 300.

[0050] When the filter element structure 100 is submerged or in a high-flow-rate scenario, the mineral content in the water may be too high or below standard. Gas can be introduced into the filter element structure 100 or the gas in the filter element structure 100 can be discharged through the air guide pipe 400 to increase or decrease the air pressure in the filter element structure 100, thereby changing the height of the first mineralizing filter material 20 immersed in the water, and thus changing the amount of minerals released by the first mineralizing filter material 20. This can effectively prevent the mineral content in the water from being too high or below standard.

[0051] Therefore, the mineral water purifier of this invention can prevent the mineral content in the water from being too high or below standard, greatly improving the user experience.

[0052] Please see Figure 2 The air guide pipe 400 includes an air guide pipe 401 and an air pressure regulating device 402. The air guide pipe 401 is connected to the air guide port 14, and the air pressure regulating device 402 is disposed on the air guide pipe 401. In specific implementation, when the filter element structure 100 is in an immersed state, the air pressure regulating device 402 can deliver gas into the filter element structure 100 through the air guide pipe 401; when the filter element structure 100 is in a high-flow scenario, the air pressure regulating device 402 can be extracted from the filter element structure 100 through the air guide pipe 401 or the gas can be discharged through the exhaust valve.

[0053] In one embodiment, the pressure regulating device 402 includes an air pump. Of course, in other embodiments, the pressure regulating device 402 may also include other devices for pressure regulation.

[0054] Please see Figure 2 The air guide pipe 400 also includes a one-way valve 403, which is located in the air guide pipe 401 and allows airflow to flow into the filter element structure 100 in one direction. In specific applications, the filter element structure 100 may also include an exhaust valve.

[0055] In one embodiment, the mineral water purifier further includes a controller (not shown), which is electrically connected to the pressure regulating device 402 and is used to control the operation and shutdown of the pressure regulating device 402. This enhances the intelligence of the mineral water purifier.

[0056] In one embodiment, the controller is also electrically connected to the exhaust valve for controlling the opening and closing of the exhaust valve.

[0057] In one embodiment, the controller is also electrically connected to the water level monitor 60. In practice, the water level information obtained by the water level monitor 60 is transmitted to the controller, which determines whether the height of the first mineralized filter material 20 immersed in the water body needs to be adjusted based on the water level information.

[0058] Please see Figure 1 and Figure 2 The mineral water purifier also includes a flow detection device 500, which is located in the inlet pipe 200 or the outlet pipe 300 to detect the water flow rate. By using the flow detection device 500 to detect the water flow rate, it is helpful to determine whether the flow rate is high, and thus whether to increase the immersion height of the first mineralized filter material 20 in the water. Of course, in other embodiments, the mineral water purifier may not include the flow detection device 500. In this embodiment, the flow detection device 500 is located in the outlet pipe 300. Of course, in other embodiments, the flow detection device 500 may also be located in the inlet pipe 200.

[0059] In one embodiment, the flow detection device 500 is a flow meter. Of course, in specific applications, as an alternative implementation, the flow detection device 500 can also be other detection devices, such as a flow velocity sensor.

[0060] In one embodiment, the flow detection device 500 is electrically connected to the controller. The flow detection device 500 can transmit the obtained water flow signal to the controller, and the controller can determine whether to increase the height of the first mineralized filter material 20 immersed in the water body based on the water flow signal.

[0061] In one embodiment, the mineral water purifier also includes a TDS (Total Dissolved Solids) detector, which is located in the outlet pipe 300 and is used to detect the TDS value of the water flow after filtration by the filter structure 100. Users can determine the mineral content in the water based on the TDS value, and thus determine whether the air pressure within the filter structure 100 needs to be adjusted.

[0062] In one embodiment, the controller is electrically connected to the TDS detector, which can transmit the obtained TDS value to the controller. The controller controls the opening or closing of the pressure regulating device 402 and the exhaust valve according to the TDS value.

[0063] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
