Description

Technical Field

[0001] This invention relates to the field of water purification technology, and more particularly to a water purifier. Background Technology

[0002] Nowadays, water sources are more polluted due to industrial and technological development. In addition, modern people are more health-conscious and have higher requirements for the quality of water they use. As a result, a large number of water purifiers are produced on the market. General water purifiers can filter out common pollutants, chlorine and impurities through different water purification methods. The current water purification methods mainly include reverse osmosis (RO) treatment, activated carbon filtration, water softening by water softeners, and distillation.

[0003] The necessity of green and environmentally friendly practices lies in ensuring the survival and development of humanity's future. With global population growth and economic development, energy consumption is constantly increasing, and limited energy resources are facing ever-growing pressure. At the same time, traditional energy utilization methods are having increasingly serious environmental impacts, such as air pollution, the greenhouse effect, and water scarcity. Therefore, we must take measures to ensure the sustainable use of energy while reducing our environmental impact. Currently, most water purifiers on the market require external power, and they fall short in terms of safety, user experience, and environmental friendliness. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention provides a water purifier.

[0005] A water purifier includes: a water purification assembly comprising a filter cartridge and a filter cartridge cover, the filter cartridge and the filter cartridge cover being detachably connected and forming a storage cavity for storing a filter element, the filter cartridge having an inlet and an outlet communicating with the storage cavity, raw water entering the storage cavity from the inlet being filtered by the filter element, and the filtered water being able to flow out through the outlet; a power generation assembly and / or a battery, the power generation assembly including a generator disposed in a water passage of the water purification assembly, the generator being used to generate electrical energy by the action of water in the water passage; and at least one light-emitting element disposed in the water passage near the outlet, the at least one light-emitting element being used to receive the electrical energy or the battery voltage and direct it toward the water filtered by the filter element.

[0006] The above technical solution has the following advantages or beneficial effects: the power generation component and / or battery and the light-emitting element are arranged near the water outlet, and the light-emitting element emits light towards the water filtered by the filter element, thereby creating a decorative effect or disinfecting the water filtered by the filter element. It is understood that placing the light-emitting element at the water outlet can achieve a better decorative effect or a better sterilization and disinfection effect, avoiding the problem of poor sterilization and disinfection effect when the pre-sterilization is performed but the filter element is contaminated.

[0007] Furthermore, the generator provides power without the need for an external power source. The generator is driven by the water flow in the waterway to generate electricity, thus realizing resource recycling and the production of new energy. In addition, due to the presence of the generator, the water flow passes through the generator, driving it to generate electrical energy, converting some of the mechanical energy of the water flow into electrical energy, thereby reducing the flow velocity of the water. In the same amount of time, less water flows out, which can reduce water waste to a certain extent and achieve resource conservation. Attached Figure Description

[0039] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment; other embodiments that conform to the spirit of the present invention may also fall within the scope of the present invention.

[0040] Please see Figures 1 to 20 The first embodiment of this application provides a water purifier 100, which is used to connect to a faucet to receive raw water and provide filtered water, including a water purification component 200, a power generation component 300 and a digital display component 400.

[0041] The water purification component 200 can be equipped with a filter element 210, which is installed in the water channel to filter the raw water to provide filtered water.

[0042] The power generation component 300 includes a generator 310 disposed in the water channel, the generator 310 being used to generate electrical energy by the action of water in the water channel.

[0043] The digital display component 400 is used to display the operating status of the water purifier 100. The operating status includes, but is not limited to, at least one of the following: the clogging lifespan of the filter element 210, the long-term lifespan of the filter element 210, the real-time water temperature, the generator speed, and the charge of the built-in battery.

[0044] The digital display component 400 includes a control unit 410 and a display unit 420.

[0045] The control unit 410 is used to acquire the initial electrical energy and real-time electrical energy of the generator 310, and calculate the clogging lifespan of the filter element 210 based on the initial electrical energy and the real-time electrical energy; and / or the control unit 410 is used to acquire the sum of the duration for which the generator 310 generates electrical energy, and calculate the duration and lifespan of the filter element 210 based on the sum of the duration. Wherein, the initial electrical energy is the initial electrical energy generated by the generator 310 detected when water flows through the water purifier 100 after the filter element is replaced, and the real-time electrical energy is the real-time electrical energy generated by the generator 310 detected during use after the filter element is replaced in the water purifier 100.

[0046] The display unit 420 is used to display the clogging lifespan and / or the duration of the filter element 210.

[0047] The water purifier 100 provided in this application includes a display unit 420 that displays the clogging lifespan and / or the duration of use of the filter element 210, prompting the user to replace the filter element in a timely manner. Furthermore, by calculating both the clogging lifespan and the duration of use, the display unit 420 can be controlled to display the lower of the two values, or to display both simultaneously or alternately. This approach not only reminds the user based on one parameter but also takes into account both the degree of clogging and the duration of use of the filter element 210, resulting in more accurate filter element replacement reminders and a better user experience.

[0048] Furthermore, the degree of filter clogging is calculated based on the initial electrical energy and the real-time electrical energy. The initial electrical energy can be obtained based on factors such as the water pressure of the connected faucet, making the reference basis more accurate. Compared to the system's built-in initial electrical energy setting, this method provides a more accurate calculation of the filter clogging degree. It can be understood that the initial electrical energy can be the initial electrical energy first obtained by the control unit 410 from the generator 310 when the user turns the faucet connected to the water purifier 100 to its maximum after filter replacement.

[0049] Furthermore, in the first embodiment of this application, the generator 310 provides power without the need for an external power source. The generator 310 generates electricity driven by the water flow in the water channel, realizing resource recycling and utilization to produce new energy. In addition, due to the presence of the generator 310, the water flow passes through the generator 310, driving the generator 310 to generate electrical energy, converting part of the mechanical energy of the water flow into electrical energy, thereby reducing the flow velocity of the water flow. In the same amount of time, less water flows out, which can reduce water waste to a certain extent and achieve resource conservation.

[0050] The digital display component 400 is also used to electrically connect the generator 310 to operate under the drive of the electrical 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 electrical energy and convert it into a working voltage. The control unit 410 is used to receive the working voltage to operate; the voltage conversion circuit 510 includes a rectifier circuit U and a voltage regulator circuit 25, the rectifier circuit U being electrically connected between the generator 310 and the voltage regulator circuit 25, and the voltage regulator circuit 25 also being electrically connected to the control unit 410. It can be understood that the voltage conversion circuit 510 can convert the electrical energy generated by the generator 310 into the voltage required for the operation of the control unit 410, etc. Specifically, the generator 310 generates alternating current, therefore, the voltage conversion circuit 510 may include the rectifier circuit U and the voltage regulator circuit 25.

[0051] Furthermore, the water purifier 100 also includes an energy detection circuit 24, which is electrically connected between the voltage conversion circuit 510 and the control unit 410. The energy detection circuit 24 receives voltage from the voltage conversion circuit 510 to detect and obtain the initial energy and the real-time energy or the sum of the duration, and provides the initial energy and the real-time energy or the sum of the duration to the control unit 410. The energy detection circuit 24 is also electrically connected to the rectifier circuit U to receive the rectified voltage output by the rectifier circuit U and performs detection based on the rectified voltage.

[0052] Further, the initial electrical energy is the first signal detected by the power detection circuit 24 when water flows through the water purifier 100 after the filter element is replaced, including the current generated by the generator 310, real-time voltage, electrical energy per unit time (i.e., electrical quantity), frequency of alternating current, electromotive force, or rotational speed. The at least one first signal is used as the initial electrical energy. The real-time electrical energy is the second signal detected by the power detection circuit 24 when water flows through the water purifier 100 after the filter element is replaced, including the current generated by the generator 310, real-time voltage, electrical energy per unit time (i.e., electrical quantity), frequency of alternating current, electromotive force, or rotational speed. The at least one second signal is used as the real-time electrical energy. This application mainly uses electrical energy per unit time (i.e., electrical quantity) as an example for explanation, but it is not limited to this.

[0053] It is understood that, in one embodiment, the control unit 410 is used to calculate the ratio of the real-time electrical energy to the initial electrical energy, and the difference between 1 and the ratio is taken as the blocking lifespan, such as... Figure 19 As shown in Figure 20, the display unit 420 is used to display the blockage lifespan or the duration lifespan using an energy bar, a number from 0 to 100, or a percentage; the control unit 410 is also used to calculate the duration lifespan based on the sum of the durations and a preset filter cartridge usage duration threshold.

[0054] Furthermore, the water purifier 100 includes a temperature acquisition circuit 23 disposed in the water channel. The control unit 410 is electrically connected to the temperature acquisition circuit 23. The temperature acquisition circuit 23 is used to acquire the real-time water temperature of the water flowing through the water purifier 100, obtain a water temperature detection signal, and provide the water temperature detection signal to the control unit 410 after smoothing the water temperature detection signal. The control unit 410 is used to control the display unit 410 to display the real-time water temperature according to the water temperature detection signal.

[0055] Furthermore, the control unit 410 is also used to control the reset of the blockage lifespan and / or the duration lifespan to the initial value when the filter element is replaced next time; the water purifier 100 has a reset component 511, which is electrically connected to the control unit 410. The reset component 511 is used to generate a reset signal by user operation, and the control unit 410 is used to reset the blockage lifespan and / or the duration lifespan to the initial value according to the reset signal. It can be understood that through the reset component 511, the initial electrical 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 system's built-in initial electrical energy setting value, the calculation of the filter element blockage degree is more accurate.

[0056] In one modified embodiment, the water purifier 100 further includes a battery 512 and a charging management circuit 513. The charging management circuit 513 is electrically connected between the voltage conversion circuit 510 and the battery 512. The charging management circuit 513 is used to receive the voltage from the voltage conversion circuit 510 and charge the battery 512. The battery 512 is electrically connected to the control unit 410 and supplies power to the control unit 410 when the generator 310 cannot support the operation of the control unit 410.

[0057] Specifically, the display unit 420 may include a plurality of LEDs 421 and a light-transmitting cover 422 surrounding the plurality of LEDs 421. The control unit 410 is used to control the switching of the plurality of LEDs 421, so that the plurality of LEDs 421 display the clogging lifespan or the duration of the filter element 210 through the light-transmitting cover 422. The display unit 420 also includes a decorative cover 423, which covers the side of the light-transmitting cover 422 away from the plurality of LEDs 421. The digital display assembly 400 also includes a main circuit board 430, on which the control unit 410 and the plurality of LEDs 421 are disposed. The control unit 410 is located on the surface of the main circuit board 430 away from the plurality of LEDs 421. The LEDs 421 may include a plurality of first LEDs 4211 corresponding to the temperature display area 4221 and a plurality of second LEDs 4212 corresponding to the clogging lifespan or the duration of the filter element.

[0058] The water purifier 100 further includes at least one light-emitting element 520, which is disposed in the water passage near the outlet 202. The light-emitting element 520 emits light towards the water filtered by the filter element 210 to create a decorative effect or to disinfect the water filtered by the filter element 210. The at least one light-emitting element 520 emits visible light and / or ultraviolet light. The at least one light-emitting element 520 is electrically connected to the generator 310 and receives electrical energy for operation. The power generation assembly 300 further includes a generator housing 320, through which the at least one light-emitting element 520 and the generator 310 are encapsulated. The generator 310 includes a power generation body 311 and an impeller 312 connected to the power generation body 311. The impeller 312 rotates under the action of water in the water passage, causing the power generation body 311 to generate electrical energy. The power generation assembly 300 also includes an impeller cover 330, which is disposed on the impeller 312. The impeller cover 330, located on one side of the power generation body 311 and detachably connected to the generator housing 320, has multiple impeller inlets 331 and multiple water guide vanes 332 adjacent to the impeller inlets 331 on its outer side wall. The temperature acquisition circuit 23 includes a sensing element R2, which, along with the at least one light-emitting element 520 and the generator 310, is encapsulated together through the generator housing 320. The sensing element R2 and the at least one light-emitting element 520 are mounted on a circuit board 521 located on the side of the power generation body 311 away from the impeller 312. In this embodiment, the number of the at least one light-emitting element 520 can be multiple, such as four. The sensing element R2 may include a thermistor.

[0059] The water purification assembly 200 further includes a filter cartridge 220 and a filter cartridge cover 290. The filter cartridge 220 and the filter cartridge cover 290 are detachably connected and form a receiving cavity 203 for housing the filter element 210. The filter cartridge 220 has an inlet 201 and an outlet 202 communicating with the receiving cavity 203. The inlet 202, the receiving cavity 203, and the outlet 202 are all located in the water passage, so that the raw water entering the receiving cavity 203 from the inlet 201 can be filtered by the filter element 210, and the filtered water can pass through the outlet 290. 2. Outflow; The filter bucket 220 has a water outlet cover 221 and a power generation component mounting structure 222. The water outlet cover 221 is provided with a water outlet 202, which may include multiple water outlet holes 2021. The power generation component 300 is mounted on the power generation component mounting structure 222. The water outlet cover 221 and the power generation component mounting structure 222 can be integrally formed or assembled separately. This embodiment mainly uses the separate assembly of the water outlet cover 221 and the power generation component mounting structure 222 as an example for illustrative explanation. At least part of the water outlet cover 221 is made of light-transmitting material.

[0060] The filter cartridge 220 has an inner shell 223 and an outer shell 224. The outer shell 224 at least partially covers the inner shell 223. The outer shell 224 may include a metal material, and the inner shell 223 may include a plastic material. The water outlet cover 221 and the power generation component mounting structure 222 are both disposed on the inner shell 223. The power generation component mounting structure 222 includes an inner ring wall 226 and an outer ring wall 227 located around the inner ring wall 226. The mounting groove 215 is used to receive at least a portion of the inner ring wall 226. The inner side of the mounting groove 215 is used to abut and fix with the inner ring wall 226, and / or the outer side of the side wall structure is used to abut and fix with the inner side of the outer ring wall 227, thereby realizing the detachable connection between the filter element 210 and the power generation component mounting structure 222.

[0061] The power generation component mounting structure 222 has an inner shell portion 225 and a power generation chamber 226. The power generation chamber 225 is disposed on the inner shell portion 226, and the power generation component 300 is installed inside the power generation chamber 225. The power generation chamber 225 includes an inner ring wall 226, an outer ring wall 227, and a connecting wall 228 connecting the inner ring wall 226 and the outer ring wall 227. At least one of the inner ring wall 226 and the outer ring wall 227 is detachably installed with the filter element 210. The power generation component 300 is disposed in the inner ring wall 226 and is provided corresponding to the filter element outlet 2101. The inner ring wall 226 and the outer ring wall 227 also have wiring notches 229, through which the electrical connection wires 340 of the power generation component 300 extend to be electrically connected to the digital display component 400; the inner shell 223 forms the water channel with the water inlet 201, the water outlet 202, the water inlet channel 204 located between the water inlet 201 and the receiving cavity 203, and the water outlet channel 205 located between the receiving cavity 203 and the water outlet 202, and the generator component mounting structure 222 and the power generation component 300 are positioned corresponding to the water outlet channel 205.

[0062] The inlet 201 faces the first side 2201 of the filter barrel 220 (as shown above), and the outlet 201 faces the second side 2202 of the filter barrel 220. The first side 2201 and the second side 2202 are opposite sides. The inlet 201 and the outlet 202 are arranged opposite to or offset from each other (this embodiment mainly uses the offset arrangement as an example for explanation). The removal direction of the filter barrel cover 290 or the removal direction of the filter element 210 faces the first side 2201 or the third side 2203 adjacent to both the first side 2201 and the second side 2202. The filter barrel 220 also has a digital display component mounting cavity 230. The component mounting cavity 230 communicates with the wiring notch 229 through an opening 231 in the cavity wall. The digital display component 400 is disposed in the digital display component mounting cavity 230. The end of the electrical connection line 340 away from the generator 310 has a first connector 341, and the digital display component 400 has a second connector 441. The first connector 341 and the second connector 441 are inserted into each other. The opening 231 in the cavity wall is provided with waterproof sealant 342 surrounding the electrical connection line 340. The digital display component mounting cavity 230 is located on the fourth side 2204 of the filter barrel 220, which is adjacent to both the first side 2201 and the second side 2202. The fourth side 2204 may be different from the third side 2203.

[0063] The filter cartridge 220 also includes a switching valve assembly 240, which is configured corresponding to the inlet 201. Under user operation, the switching valve assembly 240 allows selection of whether to filter the water at the inlet 201 by connecting the water path between the inlet 201 and the receiving cavity 203, or by directly connecting the inlet 201 to the outlet 202 or another outlet 202'. The switching valve assembly 240 may include an operating component 241 and a water path switching component 242 connected to the operating component 241. The operating component 242 is for user operation, and the water path switching component 242 moves under the action of the operating component 242 to switch the water path. The operating component 242 may be a knob or a button with a pressing bevel, and is not necessarily limited to the above. The switching valve assembly 240 is located on a fifth side 2205 adjacent to both the first side 2201 and the second side 2202, and the fifth side 2205 is opposite to the third side 2203. In this embodiment, the filter cartridge 220 includes a main body 220a and a water inlet 220b, which are detachably connected. A water inlet 201 is disposed in the water inlet 220b. The main body 220a has a receiving cavity 203 and a water outlet 202. It can be understood that the detachable connection between the main body 220a and the water inlet 220b reduces the molding difficulty of the filter cartridge 220, and also facilitates the replacement of parts.

[0064] like Figure 1-2 As shown, in this embodiment, the water purifier 100 includes two outlets 202 and 202'. One outlet 202 is directly connected to the receiving cavity 203, and the other outlet 202' is connected to the inlet 201 through the switching valve assembly. The removal direction of the filter cover 290 or the removal direction of the filter element 210 is towards the first side 2201.

[0065] Furthermore, such as Figure 7 and Figure 8As shown, the filter element 210 includes a filter element body 211 and a filter element mounting cover 212 connected to one side of the filter element body 211. The filter element mounting cover 212 has the filter element outlet 2101. At least the outer surface of the filter element body 211 is used to form a water channel between itself and the cavity wall of the receiving cavity 203. The water channel is used to receive water from the inlet 201, and the water filtered by the filter element body 211 flows out of the receiving cavity 203 through the filter element outlet 2101. The filter element mounting cover 212 includes a support member 213 and a side wall structure 214 surrounding the support member 213. The side wall structure 214 and the support member 213 form a mounting groove 210. 15. The mounting groove 215 is used to receive at least a portion of the inner ring wall 226. The inner side of the mounting groove 215 is used to abut and fix with the inner ring wall 226, or the outer side of the side wall structure 214 is used to abut and fix with the inner side of the outer ring wall 227, thereby realizing the detachable connection between the filter element 210 and the power generation chamber 225. The side wall structure 214 is also provided with at least one sealing ring 216, which is used to achieve a sealed connection between the outer side of the side wall structure 214 and the inner side of the outer ring wall 227. The side wall structure 214 has a sealing ring receiving groove 2141, and the sealing ring 216 is disposed in the sealing ring receiving groove 2141. It can be understood that the design of the filter element mounting cover 212 makes the filter element 210 have the technical effects of simple structure, stable installation, and convenient disassembly and assembly. The sealing ring 216 can not only achieve water sealing, but also improve installation stability.

[0066] The control unit 410 can be a control chip, such as an MCU, and can internally run a data display system, such as... Figure 21-24 As shown, the data display system may include:

[0067] The data recording module 1 is used to detect and record the initial electrical energy generated by the generator when the water purifier filter is replaced and water flows through the water purifier, and to detect the real-time electrical energy generated by the generator during the use of the water purifier after the filter is replaced.

[0068] The lifespan calculation module 2 is connected to the data recording module 1. It is used to calculate the degree of filter blockage based on real-time electrical energy and initial electrical energy, and display the degree of blockage through a digital display component. When the degree of blockage is determined, the user is prompted to replace the filter when the filter has reached the end of its service life.

[0069] Specifically, many existing water purifiers only have water purification functions and lack digital display functions, which makes it impossible for users to accurately know the current status of the filter cartridges used in the water purifier. Furthermore, even if some existing water purifiers have digital display functions, they can only display some basic data such as the current room temperature, current water temperature, and current water flow rate, and cannot reflect the status of the filter cartridges. As a result, users do not know clearly when to replace the filter cartridges. Often, using filter cartridges that have exceeded their service life not only fails to purify the water but also causes bacteria to grow due to the long-term lack of filter replacement, affecting the user's water quality.

[0070] Therefore, in this embodiment, a data display system for a water purifier is provided. This system can be used in conjunction with the power detection circuit installed in the water purifier, and the power used by this system is generated by the generator in the water purifier, which is green and environmentally friendly.

[0071] After the water purifier filter is replaced and water flows through it, this system detects the initial electrical energy generated by the generator and monitors the real-time electrical energy generated by the generator during use after the filter replacement. By calculating the electrical energy generated by the generator during the first use after filter replacement and during subsequent use, the system reflects changes in water flow rate, which in turn reflects the degree of filter blockage. This helps to inform the user of the current lifespan of the filter and prompts the user to replace the filter when the degree of blockage indicates that the filter has reached its lifespan.

[0072] In a preferred embodiment of the present invention, the water purifier is equipped with an electrical energy detection circuit, which is connected to a generator, then... Figure 21 As shown, data recording module 1 includes:

[0073] The initial detection unit 11 is used to detect the electrical energy generated by the generator in a unit time as the initial electrical energy when the filter element of the water purifier is replaced and a stable water flow passes through the water purifier for the first time.

[0074] The real-time detection unit 12 is used to detect the electrical energy generated by the generator within a unit time as real-time initial electrical energy when water flows through the water purifier after the filter element is replaced.

[0075] Specifically, such as Figure 16-18 As shown, in this embodiment, a power detection circuit is provided, and the power detection circuit includes:

[0076] The first resistor R1 has one end connected to the chip and the other end connected to the power supply terminal of the generator.

[0077] The first field-effect transistor MOS1 has its collector connected to the other end of the first resistor R1, its emitter connected to one end of the second resistor R2 and grounded, and its base connected to the other end of the second resistor R2 and one end of the third resistor R3. The other end of the third resistor R3 is connected to the detection terminal of the generator.

[0078] In a preferred embodiment of the present invention, the lifetime calculation module 2 includes:

[0079] The blockage degree calculation unit 21 is used to calculate the ratio of real-time electrical energy to initial electrical energy when real-time electrical 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.

[0080] Replacement prompt unit 22 is connected to 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 the preset blockage degree threshold.

[0081] Specifically, in this embodiment, based on existing electrical technologies, we know that electrical energy can be calculated using the following formula:

[0082] W=UIt;

[0083] When a stable water flow passes through the water purifier, the internal generator generates electricity under the drive of the water flow, converting 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 in this unit of time using a preset duration (e.g., set to 1s, 2s, etc.) as a unit of time.

[0084] When the filter cartridge is used for the first time after replacement, the electrical energy generated by the generator in one unit of time is calculated as the initial electrical energy. During subsequent use, the electrical energy generated by the generator in one unit of time is calculated as the real-time electrical energy. During use, the filter cartridge may become clogged, and the generated real-time electrical energy will be lower than the initial electrical energy. Therefore, the ratio of the real-time electrical energy to the initial electrical energy can reflect the current degree of clogging. We take the difference between 1 and the ratio as the degree of clogging. Since the water flow rate cannot be guaranteed to be the same every time, the degree of clogging is expressed as a multiple of ten using the ten-part attenuation method. When the final generated real-time electrical energy is lower than 10% of the initial electrical energy (which means the degree of clogging is 90%), the user is prompted to replace the filter cartridge.

[0085] The decimal attenuation method is a method for tuning controller parameters. Its basic idea is to determine the proportional gain and attenuation period of the controller by causing the system to generate damped oscillations, and then calculate the controller parameter values ​​according to the corresponding formulas.

[0086] The specific steps of the decimal attenuation method are as follows:

[0087] In a closed-loop control system, the controller is first converted to a pure proportional action, and the proportional gain is preset to a large value.

[0088] After reaching stability, a step disturbance is introduced by changing the given value. The decay ratio of the controlled variable is observed on the recorded curve. Then, the proportional gain is changed from large to small until a decay ratio of 10:1 appears. The proportional gain at this time is recorded as ∂s (called the 10:1 decay proportional gain). The decay period Ts is obtained from the curve.

[0089] Then, the parameter settings of the controller are calculated according to the formula.

[0090] In a preferred embodiment of the present invention, such as Figure 16-18 As shown, the water purifier also includes a temperature acquisition circuit, and the data display system further includes:

[0091] 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 acquisition circuit 23, and then display the real-time water temperature through the digital display component after performing differential smoothing processing.

[0092] like Figure 16-18 As shown, the temperature acquisition circuit 23 includes:

[0093] The first capacitor C1 has one end connected to the chip and one end of the third resistor R3, and the other end of the first capacitor C1 is connected to one end of the third resistor R3 and grounded. The other end of the fourth resistor R4 is connected to the other end of the third resistor R3.

[0094] Specifically, in this embodiment, the system is also equipped with a temperature acquisition circuit 23 to detect the water temperature of the water flowing through the water purifier;

[0095] In addition, although this embodiment does not mention parameters such as water flow rate and water pressure, in practice, this system can be combined with the hardware set in the water purifier, such as displaying the parameters detected by various detection circuits and sensors on the digital display component to reflect other parameters about water flow for users to view.

[0096] In a preferred embodiment of the present invention, the water purifier is further provided with a timing circuit connected to the generator 310, then as follows: Figure 21 As shown, data recording module 1 also includes:

[0097] The duration recording unit 13 is used to record the total duration of the generator's power generation as the usage duration, starting from the time the water purifier's filter cartridge is replaced, and to display this duration via a digital display component. The usage duration is also reset when the filter cartridge is replaced next time.

[0098] In a preferred embodiment of the present invention, such as Figure 21 As shown, the lifespan calculation module 2 also includes a duration prompting unit 23;

[0099] The duration reminder unit 23 is used to remind the user that the filter element has reached its service life and needs to be replaced when the usage time exceeds the preset filter element usage time threshold.

[0100] Specifically, in this embodiment, the lifespan of the filter cartridge can be reflected not only by the degree of clogging but also by the duration of its use. For example, based on an average household usage of 2 hours per day for 3 months (180 hours total), the filter cartridge's lifespan is calculated using a fuzzy algorithm. Once the usage time reaches 180 hours, the filter cartridge's lifespan ends and it needs to be replaced. Therefore, when a generator is detected generating electricity, it indicates that water is flowing through the filter cartridge. Recording the generator's duration allows us to determine the total usage time of the filter cartridge from its replacement to the current moment. When the usage time reaches 180 hours, the filter cartridge's lifespan ends, prompting the user to replace it. Meeting either the degree of clogging or the desired usage time indicates that the filter cartridge needs replacement.

[0101] This invention also provides a data display method for a water purifier, which, when applied to the data display system described above, then... Figure 22 As shown, the data display methods include:

[0102] Step S1: The data display system detects the initial electrical energy generated by the generator when the water purifier filter is replaced and water flows through the water purifier, and detects the real-time electrical energy generated by the generator during the use of the water purifier after the filter is replaced.

[0103] Step S2: The data display system calculates the degree of filter blockage based on real-time and initial electrical energy, and displays the degree of blockage through a digital display component. The system then determines whether the filter has reached the end of its service life based on the degree of blockage.

[0104] If so, prompt the user to replace the filter.

[0105] If not, return to step S2.

[0106] In a preferred embodiment of the present invention, such as Figure 23 As shown, step S1 includes:

[0107] Step S11: The data shows that after the water purifier filter is replaced and there is a stable flow of water through the water purifier for the first time, the power detection circuit detects the power generated by the generator in one unit of time as the initial power energy.

[0108] Step S12: The data display system detects the electrical energy generated by the generator within a unit of time as real-time initial electrical energy when water flows through the water purifier after the filter cartridge is replaced.

[0109] In a preferred embodiment of the present invention, such as Figure 24 As shown, step S2 includes:

[0110] Step S21: During the use of the water purifier after the filter cartridge is replaced, the data display system detects the real-time electrical energy and calculates the ratio of the real-time electrical energy to the initial electrical energy. The difference between 1 and the ratio is used as the degree of blockage.

[0111] Step S22: The data shows whether the system determines the degree of congestion to be greater than a preset congestion threshold.

[0112] If so, the user will be prompted that the filter has reached the end of its service life and needs to be replaced.

[0113] If not, return to step S21.

[0114] In a preferred embodiment of the present invention, such as Figure 16-18 As shown, the water purifier also has a temperature acquisition circuit, so the data display methods also include:

[0115] Step A1: The data display system collects the real-time water temperature of the water flowing through the water purifier through the temperature acquisition circuit 23, and displays the real-time water temperature through the digital display component after performing differential smoothing processing.

[0116] Please see Figures 25-27 The second embodiment of this 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. The direction of removal of the filter cover 690 or the direction of removal of the filter element 610 is different from that of the first embodiment. It can be seen that the direction of removal of the filter cover 690 or the direction of removal of the filter element 610 is towards 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.

[0117] Please see Figures 28-30 The third embodiment of this 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. The generator 710 and the light-emitting element 720 are arranged near the water outlet 702. The electrical energy generated by the generator 710 (or the voltage of the built-in battery) is used to power the light-emitting element 720, causing the light-emitting element 720 to emit light towards the water filtered by the filter element 710, thereby creating a decorative effect or disinfecting the water filtered by the filter element 710. It can be understood that placing the light-emitting element 720 at the water outlet 702 can achieve a better decorative effect or a better sterilization and disinfection effect, avoiding the problem of poor sterilization and disinfection effect when the pre-sterilization is poor but the filter element is contaminated.

[0118] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made using the content of this specification and illustrations should be included within the protection scope of the present invention.
