[0029] Refer to Figure 1 、 Figure 2 and Figure 3 and

[0030] First Embodiment

[0031] Refer to Figure 1 、 Figure 2 and Figure 3, the filter element 200 is arranged inside the housing 100. The filter element 200 is used to filter and purify water, so as to ensure that the water purification faucet 10 has a high purification effect on water. The flow meter 300 includes a rotating wheel 310, a first magnet 320 and a sensor 330. The rotating wheel 310 is rotatably connected to the housing 100. The first magnet 320 can be fixed on the sensor 330. The sensor 330 is arranged inside the housing 100. The sensor 330 generates a square wave signal through the action of the first magnet 320 to calculate the water volume flowing through the rotating wheel 310. The sensor 330 can include a Hall sensor 330. When water flows through the rotating wheel 310, the rotating wheel 310 can rotate around its own axis under the action of the water flow. In view of the fact that the first magnet 320 is fixed on the sensor 330, the first magnet 320 can rotate synchronously with the rotating wheel 310, so that the first magnet 320 rotates relative to the sensor 330. The sensor 330 will detect the position changes of the S pole and N pole of the first magnet 320 during the rotation process. The sensor 330 will generate a square wave signal of high and low levels and input the square wave signal of high and low levels into the control element of the flow meter 300. Thus, the control element calculates the water volume flowing through the rotating wheel 310 according to the positive correlation between the square wave frequency and the water flow rate.

[0032] The flow meter 300 further includes a circuit board 340. The circuit board 340 is fixedly connected to the housing 100. The sensor 330 is arranged on the circuit board 340. The circuit board 340 is electrically connected to the power generation module 400. The control element of the flow meter 300 can also be arranged on this current board. Therefore, the circuit board 340 can be used as a carrier for carrying the sensor 330 and the control element. The circuit board 340 can be electrically connected to the power generation module 400. The electric energy generated during the operation of the power generation module 400 can be transmitted to the circuit board 340, so as to supply power to the sensor 330 and the control element on the circuit board 340, ensure that the sensor 330 and the control element can work normally, and thus effectively play the flow calculation function of the flow meter 300.

[0033] The power generation module 400 includes an impeller, a second magnet and a coil circuit. The impeller is rotatably arranged inside the housing 100. The second magnet can be fixedly arranged on the impeller. The coil circuit calculates the water volume passing through the impeller through the frequency of the current. When water passes through the impeller of the power generation module 400, the impeller will rotate and generate electricity. Moreover, the second magnet will rotate synchronously with the impeller. The rotating second magnet will be located in the closed coil circuit, and sinusoidal current changing according to the sine law will be generated at both ends of the circuit. In view of the fact that the faster the water flow rate is, the faster the impeller rotates, the frequency of the current is positively correlated with the rotation speed of the impeller. Therefore, the frequency of the current can be detected by the power generation module 400 or the calculation element in the water purification faucet 10, and thus the water volume flowing through the power generation module 400 can be calculated according to the frequency of the current.

[0034] The water purification faucet 10 further includes a control valve 500, which can be an electromagnetic control valve 500. The control valve 500 is arranged in the housing 100. When the control valve 500 switches to the first state, water enters the power generation module 400; when the control valve 500 switches to the second state, water passes through the flow meter 300 and the filter element 200 and then enters the power generation module 400. When water does not need to be filtered by the filter element 200, the water can directly flow out through the power generation module 400, that is, the water directly flows out through the power generation module 400. For example, when water is only used for power generation and cannot be used as domestic water, the water can directly pass through the power generation module 400 for power generation without flowing through the filter element 200. When water needs to be filtered by the filter element 200, the water can first pass through the flow meter 300, then through the filter element 200, and finally flow out through the power generation module 400, that is, the water flows out in sequence through the flow meter 300, the filter element 200 and the power generation module 400.

[0035] If the usage time of the water purification faucet 10 is used as the basis for judging the service life of the filter element 200, on the one hand, the time of the filter element 200 is determined according to the purchase time of the water purification faucet 10, but the purchase time is easy to forget, making it impossible to accurately judge the usage time of the water purification faucet 10, and thus impossible to accurately judge the usage time of the filter element 200, and then impossible to judge whether the filter element 200 has reached the service life. On the other hand, the service life of the filter element 200 is related to the actual usage frequency of the filter element 200. The higher the practical frequency of the filter element 200, the shorter the life. Therefore, it is impossible to accurately judge whether the filter element 200 has reached the service life according to the purchase time. Given that users cannot accurately judge whether the filter element 200 has reached the service life, when the filter element 200 continues to be used after the service life has reached, it will affect the purification effect of the water purification faucet 10.

[0036] For the water purification faucet 10 in the above first embodiment, since the water volume flowing through the power generation module 400 can be calculated by the power generation module 400, so that users can judge the water volume flowing through the water purification faucet 10, the service life of the filter element 200 can be judged more accurately according to the water volume flowing through the water purification faucet 10, so as to replace it before the filter element 200 approaches the service life, thereby ensuring that the new filter element 200 can effectively play the purification function after replacement, and thus improving the purification effect of the water purification faucet 10. Further, since the water flowing through the filter element 200 needs to pass through the flow meter 300, the water volume flowing through the filter element 200 can be more accurately determined according to the water volume calculated by the flow meter 300, so as to more accurately judge the service life of the filter element 200, ensure that it is replaced before the filter element 200 approaches the service life, thereby ensuring that the new filter element 200 can effectively play the purification function after replacement, and thus improving the purification effect of the water purification faucet 10.

[0037] The first magnet 320 includes a bar magnet, a ring magnet, a horseshoe magnet, etc. The second magnet can also include a bar magnet, a ring magnet, a horseshoe magnet, etc. The water purification faucet 10 can further include a water outlet mechanism 600. The water outlet mechanism 600 is connected to the power generation module 400. Water flows out through the power generation module and the water outlet mechanism 600, that is, the water purified by the water purification faucet 10 can be input to a specified position under the guidance of the water outlet mechanism 600.

[0038] Second Embodiment

[0039] The filter element 200 is arranged in the housing 100. The filter element 200 is used for filtering and purifying water, so as to ensure that the water purification faucet 10 has a high purification effect on water. The flow meter 300 includes a rotating wheel 310, a first magnet 320 and a sensor 330. The rotating wheel 310 is rotatably connected to the housing 100. The first magnet 320 can be fixed on the sensor 330. The sensor 330 is arranged in the housing 100. The sensor 330 generates a square wave signal through the action of the first magnet 320 to calculate the amount of water flowing through the rotating wheel 310. The sensor 330 can include a Hall sensor 330. When water flows through the rotating wheel 310, the rotating wheel 310 can rotate around its own axis under the action of the water flow. In view of the fact that the first magnet 320 is fixed on the sensor 330, the first magnet 320 can rotate synchronously with the rotating wheel 310, so that the first magnet 320 rotates relative to the sensor 330. The sensor 330 will detect the position change of the S pole and N pole of the first magnet 320 during the rotation process. The sensor 330 will generate a square wave signal of high and low levels and input the square wave signal of high and low levels to the control element of the flow meter 300. Therefore, the control element calculates the amount of water flowing through the rotating wheel 310 according to the positive correlation between the square wave frequency and the water flow rate.

[0040] The flow meter 300 further includes a circuit board 340. The circuit board 340 is fixedly connected to the housing 100. The sensor 330 is arranged on the circuit board 340. The circuit board 340 is electrically connected to the power generation module 400. The control element of the flow meter 300 can also be arranged on the current board. Therefore, the circuit board 340 can be used as a carrier for the sensor 330 and the control element. The circuit board 340 can be electrically connected to the power generation module 400. The electric energy generated during the operation of the power generation module 400 can be transmitted to the circuit board 340, so as to supply power to the sensor 330 and the control element on the circuit board 340, ensure that the sensor 330 and the control element can work normally, and thus effectively exert the flow calculation function of the flow meter 300.

[0041] The power generation module 400 includes an impeller, a second magnet and a coil loop. The impeller is rotatably arranged in the housing 100. The second magnet can be fixedly arranged on the impeller. The coil loop calculates the amount of water passing through the impeller through the frequency of the current. When water passes through the impeller of the power generation module 400, the impeller will rotate and generate electricity, and the second magnet will rotate synchronously with the impeller. The rotating second magnet will be located in a closed coil loop, and both ends of the loop will generate a sinusoidal current that changes according to the sinusoidal law. In view of the fact that the faster the water flow speed, the faster the impeller speed, the frequency of the current is positively correlated with the speed of the impeller. Therefore, the frequency of the current can be detected by the computing element in the power generation module 400 or the water purification faucet 10, so as to calculate the amount of water flowing through the power generation module 400 according to the frequency of the current.

[0042] The water purifying faucet 10 further includes a control valve 500, which may be an electromagnetic control valve 500. The control valve 500 is disposed in the housing 100. When the control valve 500 is switched to the first state, water enters the power generation module 400; when the control valve 500 is switched to the second state, water enters the power generation module 400 through the flow meter 300 and the filter element 200. When the water does not need to be filtered through the filter element 200, the water can be made to flow directly out through the power generation module 400, that is, the water flows out directly through the power generation module 400. For example, when the water is only used for power generation and cannot be used as domestic water, the water can be made to generate electricity directly through the power generation module 400 without flowing through the filter element 200. When the water needs to be filtered through the filter element 200, the water can first pass through the flow meter 300, then through the filter element 200, and finally through the power generation module 400, that is, the water flows out through the flow meter 300, the filter element 200 and the power generation module 400 in sequence.

[0043] If the usage time of the water purification faucet 10 is used as the basis for judging the life of the filter element 200, on the one hand, the life of the filter element 200 is determined according to the purchase time of the water purification faucet 10, but the purchase time is easy to forget, so that the usage time of the water purification faucet 10 cannot be accurately judged, and thus the usage time of the filter element 200 cannot be accurately judged, and then it is impossible to judge whether the filter element 200 has reached the end of its service life. On the other hand, the service life of the filter element 200 is related to the actual frequency of use of the filter element 200. The higher the practical frequency of the filter element 200, the shorter the life, so it is impossible to accurately judge whether the filter element 200 has reached its service life based on the purchase time. Since the user cannot accurately judge whether the filter element 200 has reached its service life, if the filter element 200 continues to be used after its service life has reached, it will affect the purification effect of the water purification faucet 10.

[0044] Regarding the water purification faucet 10 in the above second embodiment, since the water volume flowing through the power generation module 400 can be calculated by the power generation module 400, so that the user can judge the water volume flowing through the water purification faucet 10, the service life of the filter element 200 can be judged more accurately according to the water volume flowing through the water purification faucet 10, and thus it can be replaced before the filter element 200 approaches its service life, thereby ensuring that the new filter element 200 after replacement can effectively play the purification function, and thus improving the purification effect of the water purification faucet 10. Further, since the water flowing through the filter element 200 needs to pass through the flow meter 300, the water volume flowing through the filter element 200 can be determined more accurately according to the water volume calculated by the flow meter 300, so as to more accurately judge the service life of the filter element 200, ensure that it is replaced before the filter element 200 approaches its service life, and thus ensure that the new filter element 200 after replacement can effectively play the purification function, and thus improve the purification effect of the water purification faucet 10.

[0045] The first magnet 320 includes a bar magnet, a ring magnet or a horseshoe magnet, etc. The second magnet may also include a bar magnet, a ring magnet or a horseshoe magnet, etc. The water purification faucet 10 may further include a water outlet mechanism 600, and the water outlet mechanism 600 is connected to the power generation module 400, and the water flows out through the power generation module and the water outlet mechanism 600, that is, the water purified by the water purification faucet 10 can be input to the designated position under the guidance of the water outlet mechanism 600.

[0046] Both the power generation module 400 and the flow meter 300 are located on the same side of the filter element 200, so that it is convenient for the components of each element in the entire water purification faucet 10. On the one hand, it can facilitate the assembly of the water purification faucet 10, thereby improving the assembly efficiency of the water purification faucet 10 and finally reducing the assembly cost and manufacturing cost of the water purification faucet 10. On the other hand, it can simplify the structure of the water purification faucet 10, thereby realizing the miniaturized design of the water purification faucet 10, and further reducing the manufacturing cost of the water purification faucet 10. In other embodiments, the power generation module 400 and the flow meter 300 may be located on different sides of the filter element 200, as long as the flow meter 300 is connected in series with the filter element 200 in the water path.

[0047] In some embodiments, the water outlet mechanism 600 includes a first rotating arm 610, a second rotating arm 620, and a water outlet assembly 630. Water sequentially passes through the first rotating arm 610 and the second rotating arm 620 and flows out from the water outlet assembly 630. The first rotating arm 610 is rotationally connected to the housing and the second rotating arm 620. The water outlet assembly 630 is rotationally connected to the second rotating arm 620. The first rotating arm 610 rotates relative to the housing 100 around a rotating shaft extending along the power generation module axis 400. The second rotating arm 620 rotates relative to the first rotating arm 610 around a rotating shaft extending perpendicular to the power generation module axis 400. The rotating shaft around which the water outlet assembly 630 rotates relative to the second rotating arm 620 is parallel to the rotating shaft around which the second rotating arm 620 rotates relative to the first rotating arm 610. By the rotation of the first rotating arm 610, the second rotating arm 620, and the water outlet assembly 630, the water outlet assembly 630 can have more degrees of freedom, so that the water flowing out from the water outlet assembly 630 can reach a specified position, ultimately improving the convenience of using the water purifying faucet 10.

[0048] The water outlet assembly 630 can adjust the outflow form of water. For example, the water can be made to flow out in a spray shape or a column shape. The water flowing out from the water outlet assembly 630 can be used for washing the face or rinsing the mouth, etc. When used for rinsing the mouth, through the adjustment of the control valve 500, the water flows out after being purified by the filter element 200. When used for washing the face, through the adjustment of the control valve 500, the water can flow out without passing through the filter element 200. In other embodiments, when used for washing the face, through the adjustment of the control valve 500, the water can also flow out after passing through the filter element 200. The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0049] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
