[0029] Embodiments of the present invention will be described in detail below. The embodiments described with reference to the drawings are exemplary. Embodiments of the present invention will be described in detail below.

[0030] Reference will be made below to Figure 1 - Figure 2 Describe a filter element identification system according to an embodiment of the present invention. The present invention also provides a water purification device having the above filter element identification system.

[0031] As Figure 1As shown, the filter element identification system includes: a pump body 40, a water circuit control component (not shown in the figure), and a control device 30. The pump body 40 is connected to the water circuit. The pump body 40 can be a booster pump, which can pressurize the filtered water and increase the water flow rate, thereby ensuring the continuous flow of water in the water circuit. The water circuit control component is arranged in the water circuit, on one side of the pump body 40, and is spaced from the pump body 40. The water circuit control component selectively controls the connection between the water circuit and the corresponding filter element 20, so that the filtered water can flow from the water circuit into the corresponding filter element 20, or flow from the corresponding filter element 20 into the water circuit.

[0032] As Figure 1 and Figure 2 shown, the control device 30 is used to identify the identity information of different filter elements 20. The control device 30 is electrically connected to the pump body 40 and the water circuit control component respectively. After the filter element 20 is installed in the filter element installation space 122, the control device 30 identifies the identity device 50 and controls the water circuit control component to connect the filter element 20 and adjust the pump body 40 to a predetermined flow rate.

[0033] Thus, through the control device 30, the identity information of different types of filter elements 20 can be identified. After identifying the identity of the filter element 20, the control device 30 can control the water circuit connection of the water circuit control component and the rotation speed of the pump body 40, so that the filter element 20 can work at a matching flow rate, better meet the needs of users, and enhance the user's drinking pleasure.

[0034] Furthermore, the present invention also proposes a water purification device S with a filter element identification system. The water purification device S includes: a body 10, a filter element 20, and a filter element identification system. A water circuit is formed inside the body 10, and the pump body 40 is connected to the water circuit.

[0035] As Figure 1 and Figure 2 shown, the body 10 is provided with a filter element installation space 122. The filter element 20 is installed in the filter element installation space 122. The filter element 20 includes an identity device 50, and the identity device 50 carries the identity information of the filter element 20. The identity information at least includes the type of the current filter element 20. For example, the ultrafiltration filter element carries the identity information of the ultrafiltration filter element, and the reverse osmosis filter element carries the identity information of the reverse osmosis filter element. Their identity information is different, so they can be identified and distinguished.

[0036] As Figure 1 and Figure 2As shown, the control device 30 is provided on the body 10, and the control device 30 is used to identify the identity device 50 of the filter element 20. The control device 30 is electrically connected to the pump body 40 and the waterway control component respectively. After the filter element 20 is installed in the filter element installation space 122, the control device 30 identifies the identity device 50 and controls the waterway control component to connect the filter element 20 and adjust the pump body 40 to a predetermined flow rate.

[0037] Specifically, the filter element 20 is installed in the filter element installation space 122, and the identity device 50 is electrically connected to the control device 30, so that the control device 30 can control the connection with different filter elements 20. When the user changes the filter element according to the demand, the control device 30 can identify the identity information of the identity device 50 of the changed filter element, and thus can make corresponding adjustments. For example, the control device 30 will control the waterway control component to connect the corresponding waterway and control the pump body 40 to adjust to the preset rotation speed, so that the waterway is adjusted to the predetermined flow rate, so as to meet the normal operation of the changed filter element 20. In this way, the waterway of the corresponding filter element 20 can be connected to the water inlet and outlet of the water purification device, and the filter element 20 can work at a matching flow rate, so that the water required by the user can be obtained and the water use demand of the user can be met.

[0038] For example, the ultrafiltration filter element was installed in the water purification device before, but the user pre-changed the ultrafiltration filter element into a reverse osmosis filter element according to their own needs. The user can remove the ultrafiltration filter element and then install the reverse osmosis filter element at the corresponding filter element installation space 122. Since the reverse osmosis filter element is equipped with the corresponding identity device 50, the control device 30 will control the pump body 40 to increase the rotation speed to match the reverse osmosis filter element, and will also adjust the waterway control component to match the current reverse osmosis filter element.

[0039] Thus, through the identification connection of the control device 30 and the identity device 50, after identifying the identity of the filter element 20, the control device 30 can control the waterway connection of the waterway control component and the rotation speed of the pump body 40, so that the filter element 20 can work at a matching flow rate, better meet the needs of users, and enhance the user's drinking pleasure.

[0040] According to an alternative embodiment of the present invention, the identity device 50 can be a chip. The filter element 20 includes a housing 24, and the identity device 50 is disposed within the housing 24. When the identity device 50 is a chip, the chip can be electrically connected to the control device 30, so that the type of the current filter element 20 can be obtained according to the difference of the filter element 20, and then the flow rate of the pump body 40 can be adjusted correspondingly, enabling the filter element 20 to operate at an appropriate flow rate. Moreover, the chip is installed within the housing 24, with high recognition and not easily interfered, thereby reducing the failure rate of the water purification device S. At this time, the control device 30 can have a wireless sensor corresponding to the chip, and the wireless sensor can wirelessly transmit with the chip. The wireless sensor can be Bluetooth or an antenna.

[0041] According to another alternative embodiment of the present invention, the identity device 50 can be an electronic tag with an identification circuit, and the identity device 50 is disposed on the outer peripheral wall of the housing 24. When the identity device 50 is an electronic tag with an identification circuit, the electronic tag can be electrically connected to the control device 30. Moreover, the electronic tag has a low cost, which can save the production cost of the water purification device S. At this time, the control device 30 can be a photoelectric sensor corresponding to the electronic tag, and the photoelectric sensor can achieve information transmission with the electronic tag.

[0042] In addition, the control board 31 can be a control board 31 provided with electrical connection contacts. When the electrical connection contacts are provided on the control board 31, the electrical connection contacts are electrically connected to the electrical connection points of the chip or the electronic tag, thereby enabling signal connection between the control board and the chip or the electronic tag.

[0043] Optionally, as Figure 2 shown, the body 10 includes a waterway board 11 and a skeleton 12. The waterway board 11 forms a waterway, and the skeleton 12 is disposed on one side of the waterway board 11. The skeleton 12 defines a filter element installation space 122. By providing the skeleton 12, the filter element 20 can be installed on the waterway board 11, and it can also support the filter element 20, protecting the filter element 20 from damage.

[0044] In addition, as Figure 2 shown, a fixing portion 121 is provided on the outer side of the skeleton 12, and the control device 30 is disposed on the fixing portion 121. The control device 30 can be installed on the outer side of the skeleton 12 through the fixing portion 121, thereby facilitating the electrical connection and identification between the control device 30 and the identity device 50, and improving the installation stability of the control device 30. In addition, the fixing portion 121 can also be electrically connected to the control device 30.

[0045] In an alternative embodiment, at least one of the skeleton 12 and the filter element 20 is provided with an anti-misassembly structure to make the identity device 50 face the control device 30. By providing the anti-misassembly structure on the skeleton 12 or the filter element 20, when the filter element 20 is installed in the skeleton 12, it can be ensured that the identity device 50 and the control device 30 face each other, which can further ensure that the filter element 20 is installed in place, so that the normal electrical connection between the identity device 50 and the control device 30 can be achieved, and the accuracy of the control device 30 in identifying the identity device 50 can be improved.

[0046] In another alternative embodiment, a position indicating structure is provided at the top of the filter element 20. By providing the position indicating structure at the top of the filter element 20, when the filter element 20 is installed with the skeleton 12, if the identity device 50 and the control device 30 are not facing each other, the user can obtain confirmation through the indicated position of the position indicating structure, so that it is convenient for the identity device 50 and the control device 30 to face each other, and then the normal electrical connection between the identity device 50 and the control device 30 can be achieved.

[0047] According to an alternative embodiment of the present invention, as Figure 2 shown, there are at least two filter element installation spaces 122, the control device 30 includes at least two control boards 31, the at least two control boards 31 are spaced apart, and the at least two control boards 31 respectively correspond to the filter element installation spaces 122, so that when at least one filter element 20 is installed in the corresponding filter element installation space 122, the control board 31 identifies the identity device 50. That is to say, because a water purification device S is required to filter out different types of water, multiple filter elements 20 are used. The multiple control boards 31 can be electrically connected to different filter elements 20 respectively, and each control board 31 can control the rotation speed of the pump body 40 corresponding to the filter element 20, and further control the water flow rate. In this way, when the user switches to different filtered water, the different filter elements 20 can work at a matching flow rate, so that the filtering performance of the filter element 20 can be ensured, and the water use requirements of the user can be met.

[0048] As Figure 2 shown, a connecting plate 32 is provided between the at least two control boards 31 and forms an integral structure. By providing the connecting plate 32 between the two control boards 31, the at least two control boards 31 can be integrally formed, so that the integrally formed control boards 31 can be more convenient to install, avoiding multiple alignments of the control boards 31. Moreover, the at least two control boards 31 arranged in this way can better ensure their installation accuracy through multiple fixing parts 121, and can further ensure the accuracy of the control board 31 in identifying the identity device 50.

[0049] In addition, as Figure 2As shown, the diameters of the filter element installation spaces 122 corresponding to at least two control boards 31 of the integrated structure are the same. That is to say, when at least two control boards 31 formed integrally are installed on the skeleton 12, at least two control boards 31 formed integrally will not tilt relative to the skeleton 12, thereby facilitating the installation of the control boards 31 and the electrical connection with the identity device 50. In addition, the internal space of the water purification device S can be reasonably utilized.

[0050] According to another optional embodiment of the invention, as Figure 3 shown, the control device 30 includes: a control board 31, the control board 31 is strip-shaped and has a plurality of detection parts 33 arranged at intervals, and each detection part 33 is used to identify the identity information of a preset type of filter element 20. By arranging a plurality of detection parts 33 on one control board 31, a plurality of control boards 31 can be integrated on one control board 31, improving the integration degree of the control board 31 and facilitating the installation of the control board 31. And a plurality of detection parts 33 can respectively detect the identity information of different filter elements 20 without affecting the identification of the filter elements 20.

[0051] The water path control assembly includes at least two control valves (not shown in the figure), and the at least two control valves are respectively arranged in the water path, and the at least two control valves are selectively opened and closed through the control device 30, so that the user can switch between different filtered waters. For example, when the reverse osmosis filter element 20 is inserted, the control system starts the corresponding program, and the control system starts the pump body 40 and the corresponding control valves; when the ultrafiltration filter element 20 is inserted, the control system starts the corresponding program to reduce or increase the flow rate of the pump body 40 to match the flow rate when the ultrafiltration membrane is used, and at the same time starts the corresponding control valves.

[0052] One of the control valves can be installed at the water outlet of the first filter element 21. When the filtered water flows out of the first filter element 21, the control valve can selectively make the filtered water flow out of the water purification device S according to the signal of the control device 30. Or the filtered water can be made to flow into the second filter element 22 or the third filter element 23, so that the filtered water can be further filtered twice.

[0053] Specifically, as Figure 2As shown, there are three filter element installation spaces 122 and three filter elements 20. The three filter elements 20 are, in sequence, the first filter element 21, the second filter element 22, and the third filter element 23. At least one of the first filter element 21, the second filter element 22, and the third filter element 23 is installed in the corresponding filter element installation space 122, and the first filter element 21, the second filter element 22, and the third filter element 23 are filter elements 20 of different types. Two of the three filter elements 20 can be combined for use, thereby providing users with different filtered water. In addition, since the three filter elements 20 are filter elements 20 of different types, using a single filter element 20 alone can also provide users with different types of filtered water. Optionally, the three filter elements 20 can also be used together.

[0054] As Figure 2 shown, the body 10 includes a water circuit board 11. The water circuit board 11 forms a water circuit, and a detachable adapter water circuit board is also provided on the water circuit board 11. The adapter water circuit board can install filter elements 20 of different models on the water circuit board 11, thereby improving the modular design of the water purification device S and facilitating the replacement of different filter elements 20.

[0055] Optionally, the filter element 20 is one of a reverse osmosis filter element, an ultrafiltration filter element, and a nanofiltration filter element. The filtering performances of the above-mentioned various filter elements are different, and users can select according to actual needs.

[0056] Among them, the reverse osmosis filter element can effectively remove calcium, magnesium, bacteria, organic matter, inorganic matter, metal ions, radioactive substances, etc. in water. The water purified by this device is crystal clear, sweet and mellow.

[0057] The ultrafiltration filter element is encapsulated with high-quality hollow fiber membrane filament materials. The product has a high filling density, a large water output, and the ultrafiltration filter element has good hydrophilicity, strong anti-pollution ability, and is not easily fouled.

[0058] The nanofiltration (NF) filter element is used to separate substances with relatively small molecular weights, such as inorganic salts or small molecule organic matters such as glucose and sucrose, from the solvent.
