Description

Technical Field

[0001] The present invention relates to the technical field of water purification, and in particular to a water purifier. Background Art

[0002] Today's water sources are more polluted due to industrial and technological development. In addition, modern people have higher health awareness and higher requirements for water quality, which has led to a large number of water purifiers on the market. General water purifiers can filter out general pollutants, chlorine and impurities through different water purification methods. The current water purification methods mainly include reverse osmosis (RO) treatment, activated carbon filtration, water softener softening method, and distillation method.

[0003] The necessity of green environmental protection lies in ensuring the survival and development of mankind in the future. With the growth of the global population and the development of the economy, energy consumption is also increasing, and limited energy resources are facing increasing pressure. At the same time, the impact of traditional energy utilization on the environment is becoming more and more serious, such as air pollution, greenhouse effect, water shortage and other problems. Therefore, we must take measures to ensure the sustainable use of energy while reducing the impact on the environment. Now, even water purifiers with data display function on the market need to be powered by an external power supply, which is not good enough in green environmental protection. Therefore, a digital water purification faucet with built-in water purification function, data display and power supply using water flow new energy is needed.

[0004] Most of the current water purifiers do not have a display function and cannot display information such as water temperature. It is necessary to provide a digital faucet that has its own water purification function and can display data. At the same time, when users use water purification faucets, they often ignore the service life of the filter element and fail to replace the filter element in time, which reduces the water purification effect and affects the health of users. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a water purifier.

[0006] A water purifier, comprising

[0007] A water purification component, wherein the water purification component can be provided with a filter element, wherein the filter element is used to be arranged in the water channel and is used to filter raw water to provide filtered water;

[0008] a power generation assembly, the power generation assembly comprising a generator disposed in the waterway channel, the generator being used to generate electrical energy under the action of water in the waterway channel; and

[0009] A digital display component includes a control unit, which is used to obtain the initial electric energy of the generator and the real-time electric energy of the generator and calculate the clogging service life of the filter element based on the initial electric energy and the real-time electric energy; and / or the control unit is used to obtain the total time of the generator generating electric energy and calculate the duration service life of the filter element based on the total time; wherein the initial electric energy is the initial electric energy generated by the generator detected and obtained when water flows through the water purifier after the filter element of the water purifier is replaced, and the real-time electric energy is the real-time electric energy generated by the generator detected and obtained during the use of the water purifier after the filter element is replaced; and a display unit, which is used to display the clogging service life of the filter element and / or the duration service life of the filter element.

[0010] In the water purifier provided in the present application, the blocking service life of the filter element and / or the time service life of the filter element are provided in the display unit, so that the user can be prompted to replace the filter element in time. Moreover, by calculating the blocking service life and the time service life, the display unit can be controlled to display the lower value of the blocking service life and the time service life, and simultaneously display or alternately display the blocking service life and the time service life, so as to remind the user not only based on one parameter, but also take into account the blocking degree of the filter element and the working time of the filter element to remind the user, so as to achieve more accurate filter element replacement reminder and better user experience. In addition, the filter element blocking degree is calculated based on the initial electric energy and the real-time electric energy shown. The initial electric energy can be obtained based on factors such as the water pressure of the connected faucet, which can make the reference basis more accurate. Compared with the method of setting the initial electric energy value of the system, the calculation of the filter element blocking degree is more accurate.

[0011] In addition, the generator does not require an external power supply, and the generator is driven by the water flow in the waterway to generate electricity, thereby realizing resource recycling and generating new energy. In addition, due to the presence of the generator, the water flows through the generator, driving the generator to generate electricity, so that part of the mechanical energy of the water flow is converted into electrical energy, thereby reducing the flow rate of the water flow, and the amount of water flowing out in the same time becomes less, which can reduce the waste of water resources to a certain extent and achieve resource conservation.

[0043] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment, and other embodiments may also fall within the scope of the present invention as long as they conform to the gist of the present invention.

[0044] See also Figures 1 to 20 The first embodiment of the present application provides a water purifier 100, which is used to connect to a faucet to receive raw water and provide filtered water, and includes a water purification component 200, a power generation component 300 and a digital display component 400.

[0045] The water purification component 200 can be provided with a filter element 210, and the filter element 210 is used to be arranged in a water channel to filter raw water to provide filtered water.

[0046] The power generation assembly 300 includes a generator 310 disposed in the water channel, and the generator 310 is used to generate electrical energy under the action of water in the water channel.

[0047] The digital display assembly 400 is used to display the working state of the water purifier 100. The working state includes but is not limited to at least one of the blocking service life of the filter element 210, the long service life of the filter element 210, the real-time water temperature, the rotation speed of the generator, and the power of the built-in battery.

[0048] The digital display component 400 includes a control unit 410 and a display unit 420 .

[0049] The control unit 410 is used to obtain the initial electric energy of the generator 310 and the real-time electric energy of the generator 310 and calculate the blocking service life of the filter element 210 based on the initial electric energy and the real-time electric energy; and / or the control unit 410 is used to obtain the total duration of the generator 310 generating electric energy and calculate the service life of the filter element 210 based on the total duration. The initial electric energy is the initial electric energy generated by the generator 310 detected and obtained when water flows through the water purifier 100 after the filter element of the water purifier 100 is replaced, and the real-time electric energy is the real-time electric energy generated by the generator 310 detected and obtained during the use of the water purifier 100 after the filter element is replaced.

[0050] The display unit 420 is used to display the clogging service life of the filter element 210 and / or the length of service life of the filter element 210 .

[0051] In the water purifier 100 provided in the present application, the display unit 420 is provided to display the blocking service life of the filter element 210 and / or the long service life of the filter element 210, so as to remind the user to replace the filter element in time. Moreover, by calculating the blocking service life and the long service life, the display unit 420 can be controlled to display the lower value of the blocking service life and the long service life, to display the blocking service life and the long service life simultaneously or to display the blocking service life and the long service life alternately, so as to remind the user not only based on one parameter, but also to take into account the blocking degree of the filter element 210 and the working time of the filter element to remind the user, so as to achieve a more accurate filter element replacement reminder and a better user experience.

[0052] In addition, the degree of filter element blockage is calculated based on the initial electric energy and the real-time electric energy shown. The initial electric energy can be obtained based on factors such as the water pressure of the connected faucet, which can make the reference basis more accurate. Compared with the method of setting the initial electric energy of the system, the calculation of the degree of filter element blockage is more accurate. It can be understood that the initial electric energy can be the initial electric energy of the generator 310 obtained by the control unit 410 for the first time when the user opens the faucet connected to the water purifier 100 to the maximum after the filter element is replaced.

[0053] In addition, in the first embodiment of the present application, the generator 310 is powered by electricity without the need for an external power supply. The generator 310 is driven by the water flow in the waterway to generate electricity, thereby realizing resource recycling and generating new energy. In addition, due to the presence of the generator 310, the water flows through the generator 310, driving the generator 310 to generate electrical energy, so that part of the mechanical energy of the water flow is converted into electrical energy, thereby reducing the flow rate of the water flow. Less water flows out in the same period of time, which can reduce the waste of water resources to a certain extent and achieve resource conservation.

[0054] The digital display assembly 400 is also used to electrically connect the generator 310 to work under the drive of the electric energy; the water purifier 100 also includes a voltage conversion circuit 510, which is electrically connected between the generator 310 and the control unit 410, and is used to receive the electric energy and convert the electric energy into a working voltage, and the control unit 410 is used to receive the working voltage to work; the voltage conversion circuit 510 includes a rectifier circuit U and a voltage stabilizing circuit 25, and the rectifier circuit U is electrically connected between the generator 310 and the voltage stabilizing circuit 25, and the voltage stabilizing circuit 25 is also electrically connected to the control unit 410. It can be understood that the electric energy generated by the generator 310 can be converted into the voltage required for the control unit 410 and the like through the voltage conversion circuit 510. Specifically, the generator 310 generates alternating current, so the voltage conversion circuit 510 can include the rectifier circuit U and the voltage stabilizing circuit 25.

[0055] Furthermore, the water purifier 100 also includes an electric energy detection circuit 24, which is electrically connected between the voltage conversion circuit 510 and the control unit 410. The electric energy detection circuit 24 is used to receive voltage from the voltage conversion circuit 510 to detect and obtain the initial electric energy and the real-time electric energy or obtain the sum of the duration, and provide the initial electric energy and the real-time electric energy or the sum of the duration to the control unit 410; the electric energy detection circuit 24 is electrically connected to the rectifier circuit U to receive the rectified voltage output by the rectifier circuit U, and perform detection based on the rectified voltage.

[0056] Further, the initial electric energy is the current, real-time voltage, electric energy per unit time (i.e., electric quantity), frequency, electromotive force, or rotation speed of the generator 310 detected by the electric energy detection circuit 24 after the filter element of the water purifier 100 is replaced, and water flows through the water purifier 100, and at least one first signal is used as the initial electric energy; the real-time electric energy is the current, real-time voltage, electric energy per unit time (i.e., electric quantity), frequency, electromotive force, or rotation speed of the generator 310 detected by the electric energy detection circuit 24 in real time during the use of the water purifier after the filter element is replaced, and water flows through the water purifier 100, and at least one second signal is used as the real-time electric energy. In this application, the electric energy per unit time (i.e., electric quantity) is mainly used as an example for explanation, but it is not limited to this.

[0057] It can be understood that, in one embodiment, the control unit 410 is used to calculate the ratio of the real-time electric energy to the initial electric energy, and the difference between 1 and the ratio is used as the blocking service life, such as Fig.19 As shown in or 20, the display unit 420 is used to display the blocking service life or the duration service life in the form of an energy bar, a number from 0 to 100, or a percentage; the control unit 410 is also used to calculate the duration service life based on the sum of the durations and a preset filter element usage time threshold.

[0058] Furthermore, the water purifier 100 includes a temperature acquisition circuit 23 arranged in the water channel, and the control unit 410 is electrically connected to the temperature acquisition circuit 23.

[0070] The data recording module 1 is used to detect and record the initial electric energy generated by the generator when water flows through the water purifier after the filter element is replaced, and to detect the real-time electric energy generated by the generator during the use of the water purifier after the filter element is replaced;

[0071] The life calculation module 2 is connected to the data recording module 1, and is used to calculate the blockage degree of the filter element according to the real-time electric energy and the initial electric energy, and display the blockage degree through the digital display component, and prompt the user to replace the filter element when the filter element reaches its service life according to the blockage degree.

[0072] Specifically, since many existing water purifiers only have a water purification function but not a digital display function, users cannot accurately know the current usage status of the filter element used in the water purifier, and even if some existing water purifiers have a digital display function, they can only display some general data such as the current room temperature, the current water temperature, the current water flow rate, etc., and cannot reflect the usage status of the filter element. As a result, users cannot clearly know when to replace the filter element. Often, using some filter elements that have exceeded their service life not only results in no water purification effect, but also breeds bacteria due to long-term non-replacement of the filter element, affecting the user's water quality.

[0073] Therefore, in this embodiment, a data display system for a water purifier is provided. The system can be used in conjunction with an electric energy detection circuit installed in the water purifier, and the electric energy used by the system is generated by a generator in the water purifier, which is green and environmentally friendly.

[0074] After the filter element of the water purifier is replaced and water flows through the water purifier, the system detects the initial electric energy generated by the generator, and detects the real-time electric energy generated by the generator during the use of the water purifier after the filter element is replaced; by calculating the electric energy generated by the generator during the first use and use after the filter element is replaced, it reflects the change in water flow rate and then reflects the degree of blockage of the filter element, so as to prompt the user of the service life of the current filter element, and prompt the user to replace the filter element in time when the filter element reaches its service life based on the degree of blockage.

[0075] In a preferred embodiment of the present invention, a power detection circuit is provided in the water purifier and connected to a generator. Fig.21 As shown, the data recording module 1 includes:

[0076] The initial detection unit 11 is used to detect the electric energy generated by the generator in a unit time as the initial electric energy through the electric energy detection circuit when a stable water flow flows through the water purifier for the first time after the filter element of the water purifier is replaced;

[0077] The real-time detection unit 12 is used to detect the electric energy generated by the generator in a unit time as the real-time initial electric energy through the electric energy detection circuit when water flows through the water purifier during use after the filter element is replaced.

[0078] Specifically, Figure 16-18 As shown, in this embodiment, the electric energy detection circuit is provided, and the electric energy detection circuit includes:

[0079] A first resistor R1, one end of the first resistor R1 is connected to the chip, and the other end of the first resistor R1 is connected to the power supply end of the generator;

[0080] A first field effect transistor MOS1, a collector of the first field effect transistor MOS1 is connected to the other end of the first resistor R1, an emitter of the first field effect transistor MOS1 is connected to one end of the second resistor R2 and is grounded, a base of the first field effect transistor MOS1 is connected to the other end of the second resistor R2 and one end of the third resistor R3, and the other end of the third resistor R3 is connected to the detection end of the generator.

[0081] In a preferred embodiment of the present invention, the life calculation module 2 includes:

[0082] The blockage degree calculation unit 21 is used to calculate the ratio of the real-time electric energy to the initial electric energy when the real-time electric energy is detected during the use of the water purifier after the filter element is replaced, and the difference between 1 and the ratio is used as the blockage degree;

[0083] The replacement prompting unit 22 is connected to the blockage degree calculation unit 21 and is used to prompt the user that the filter element has reached its service life and needs to be replaced when the blockage degree is greater than a preset blockage degree threshold.

[0084] Specifically, in this embodiment, according to existing electrical technology, we know that the electric energy can be calculated according to the following formula:

[0085] W = UIt;

[0086] When a stable water flow passes through the water purifier, the internal generator generates electricity driven by the water flow to convert water energy into electrical energy. At this time, the power detection circuit detects the voltage and current of the generator to obtain the power of the generator, and calculates the electrical energy generated per unit time based on a preset time length (for example, 1s, 2s, etc.) as a unit time;

[0087] When the filter element is used for the first time after it has been replaced, the electric energy generated by the generator in a unit time is calculated as the initial electric energy. In the subsequent use process, the electric energy generated by the generator in a unit time is calculated as the real-time electric energy. During use, the filter element will be blocked, and the real-time electric energy generated will be lower than the initial electric energy. Therefore, the ratio of the real-time electric energy to the initial electric energy can reflect the current degree of blockage. We take the difference between 1 and the ratio as the degree of blockage; since the water flow rate cannot be guaranteed to be the same every time, the degree of blockage is expressed as a whole ten according to the ten-equal-division attenuation method. When the real-time electric energy generated at the end is lower than 10% of the initial electric energy (which means the degree of blockage is 90%), the user is prompted to replace the filter element.

[0088] The ten-equal-division attenuation method is a method for tuning controller parameters. Its basic idea is to determine the proportionality and attenuation period of the controller by causing the system to produce attenuated oscillations, and then calculate the controller parameter values ​​according to the corresponding formulas.

[0089] The specific steps of the ten-equal-division attenuation method are as follows:

[0090] In a closed-loop control system, the controller is first changed to a pure proportional action and the proportionality is preset to a larger value.

[0091] After reaching stability, add step disturbance by changing the given value, observe the attenuation ratio of the controlled variable recording curve, and then change the proportionality from large to small until a 10:1 attenuation ratio appears, and record the proportionality at this time. (called 10:1 attenuation ratio), and the attenuation period Ts is obtained from the curve.

[0092] Then, according to the formula, the parameter setting value of the controller is calculated.

[0093] In a preferred embodiment of the present invention, Figure 16-18 As shown, the water purifier is also equipped with a temperature acquisition circuit, and the data display system also includes:

[0094] The water temperature measurement module 3 is used to collect the real-time water temperature of the water flowing through the water purifier through the temperature collection circuit 23, and display the real-time water temperature through the digital display component after performing difference smoothing processing.

[0095] like Figure 16-18 As shown, the temperature acquisition circuit 23 includes:

[0096] The first capacitor C1 has one end connected to the chip and one end of the third resistor R3, the other end of the first capacitor C1 is connected to one end of the third resistor R3 and grounded, and the other end of the fourth resistor R4 is connected to the other end of the third resistor R3.

[0097] Specifically, in this embodiment, the system is also provided with a temperature acquisition circuit 23 to detect the water temperature of the water flowing through the water purifier;

[0098] In addition, although the detection of water flow rate, water pressure and other parameters is not mentioned in this embodiment, in actual situations, the system can be combined with the hardware set in the water purifier, such as various detection circuits and various sensors. The parameters detected are displayed on the digital display component to reflect other parameters about the water flow for users to view.

[0099] In a preferred embodiment of the present invention, a timing circuit is also provided in the water purifier to connect to the generator 310. Fig.21 As shown, the data recording module 1 also includes:

[0100] The duration recording unit 13 is used to record the total duration of the generator generating electricity starting from the time the filter element of the water purifier is replaced as the usage duration and display it through the digital display component, and reset the usage duration when the filter element is replaced next time.

[0101] In a preferred embodiment of the present invention, Fig.21 As shown, the life calculation module 2 also includes a duration prompt unit 23;

[0102] The duration prompting unit 23 is used to prompt the user that the filter element has reached its service life and needs to be replaced when the usage time is greater than a preset filter element usage time threshold.

[0103] Specifically, in this embodiment, the service life of the filter element can be reflected not only by the degree of blockage, but also by the length of time the filter element is used. For example, the filter element is used for an average of 2 hours a day in a household, which is a total of 180 hours in 3 months, and the fuzzy algorithm is used to calculate the service life of the filter element. When the usage time reaches 180 hours, the life of the filter element ends and the filter element needs to be replaced. Therefore, when the generator is detected to be generating electricity, it means that water is flowing through the filter element. By recording the generator time, it can be obtained how long the filter element has been used from replacement to the current moment. When the usage time reaches 180 hours, the life of the filter element ends, prompting the user to replace the filter element. If any of the blockage degree or usage time is met, it means that the filter element needs to be replaced.

[0104] The present invention also provides a data display method for a water purifier, which is applied to the data display system as described above. Fig. 22 As shown, the data display method includes:

[0105] Step S1, the data display system detects the initial electric energy generated by the generator when water flows through the water purifier after the filter element is replaced, and detects the real-time electric energy generated by the generator during the use of the water purifier after the filter element is replaced;

[0106] Step S2, the data display system calculates the blockage degree of the filter element according to the real-time electric energy and the initial electric energy, and displays the blockage degree through the digital display component, and determines whether the filter element has reached its service life according to the blockage degree:

[0107] If yes, the user is prompted to replace the filter element;

[0108] If not, return to step S2.

[0109] In a preferred embodiment of the present invention, Fig.23 As shown, step S1 includes:

[0110] Step S11, the data display system detects the electric energy generated by the generator in a unit time as the initial electric energy through the electric energy detection circuit after the filter element of the water purifier is replaced and a stable water flow flows through the water purifier for the first time;

[0111] Step S12, when the data display system is in use after the filter element of the water purifier is replaced, when water flows through the water purifier, the electric energy generated by the generator in a unit time is detected by the electric energy detection circuit as the real-time initial electric energy.

[0112] In a preferred embodiment of the present invention, Fig.24 As shown, step S2 includes:

[0113] Step S21, when the data display system detects and obtains real-time electric energy during use of the water purifier after replacing the filter element, the ratio of the real-time electric energy to the initial electric energy is calculated, and the difference between 1 and the ratio is used as the degree of blockage;

[0114] Step S22: The data display system determines whether the blocking degree is greater than a preset blocking degree threshold:

[0115] If so, the user is prompted that the filter element has reached its service life and needs to be replaced;

[0116] If not, return to step S21.

[0117] In a preferred embodiment of the present invention, Figure 16-18 As shown, the water purifier is also provided with a temperature acquisition circuit, and the data display method further includes:

[0118] Step A1, the data display system collects the real-time water temperature of the water flowing through the water purifier through the temperature collection circuit 23, and performs difference smoothing processing on the real-time water temperature and then displays it through the digital display component.

[0119] See also Figure 25-27 The second embodiment of the present application provides a water purifier 600. The main difference between the water purifier 600 and the water purifier 100 of the first embodiment is that the water purifier 600 only includes one water outlet 602, and the detachment direction of the filter barrel cover 690 or the detachment direction of the filter element 610 is different from that of the first embodiment. It can be seen that the detachment direction of the filter barrel cover 690 or the detachment direction of the filter element 610 is toward the third side 2203 which is different from the first side 2201, the second side 2202, the fourth side 2204 and the fifth side 2205.

[0120] See also Figure 28-Figure 30 The third embodiment of the present application provides a water purifier 700. The main difference between the water purifier 700 and the water purifier 100 of the first embodiment is that the water purifier 100 does not have a digital display component 400, and the generator 710 and the light-emitting element 720 are arranged near the water outlet 702. The electric energy generated by the generator 710 (or the voltage of the built-in battery) is used to power the light-emitting element 720, so that the light-emitting element 720 emits light toward the water filtered by the filter element 710, thereby forming a decorative effect or disinfecting the water filtered by the filter element 710. It can be understood that arranging the light-emitting element 720 at the water outlet 702 can achieve a better decorative effect or a better sterilization and disinfection effect, and avoid the problem of poor sterilization and disinfection effect when the filter element is contaminated during pre-sterilization.

Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the contents of this specification and illustrations should be included in the protection scope of the present invention.
