Description

A water purifier 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 increasingly polluted due to industrial and technological development. Coupled with rising health awareness among modern people, which places higher demands on water quality, a large number of water purifiers have been introduced to the market. Typical water purifiers can filter out common pollutants, chlorine, and impurities through various purification methods. Current water purification methods primarily include reverse osmosis (RO), activated carbon filtration, water softening, and distillation.

[0003] The necessity of green environmental protection lies in safeguarding humanity's future survival and development. With global population growth and economic development, energy consumption is also increasing, and limited energy resources are facing increasing pressure. At the same time, traditional energy utilization methods are increasingly impacting the environment, such as air pollution, the greenhouse effect, and water shortages. Therefore, we must take measures to ensure the sustainable use of energy while reducing the impact on the environment. Even water purifiers currently available on the market with data display capabilities require an external power supply, which is not a good environmental performance. Therefore, there is a need for a digital water purification faucet that has built-in water purification functions, can display data, and uses water flow as a new energy source for power.

[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 with built-in water purification function and data display. At the same time, users often ignore the service life of the filter element when using the water purification faucet, and fail to replace the filter element in time, resulting in reduced water purification effect and affecting user health. 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 includes: a water purification component, the water purification component includes a filter barrel and a filter barrel cover, the filter barrel and the filter barrel cover are detachably connected and form a storage cavity for storing a filter element, the filter barrel has a water inlet and a water outlet connected to the storage cavity, the raw water entering the storage cavity from the water inlet can be filtered through the filter element, and the filtered water can flow out through the water outlet; a power generation component, the power generation component includes a generator arranged in a water channel of the water purification component, the generator is used to generate electrical energy under the action of water in the water channel; and a digital display component, used to receive the electrical energy to work under the drive of the electrical energy, the digital display component is used to display the working status of the water purifier.

[0007] The above technical solution has the following advantages or beneficial effects: the digital display component is used to display the working status of the water purifier, which can improve the user experience, and the generator does not require an external power supply. The generator is driven by the water flow in the water channel to generate electricity, realizing resource recycling and utilization to generate 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 save resources.

[0039] The present invention is described in detail below with reference to 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.

[0040] Referring to Figures 1 to 20, a 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.

[0041] The water purification component 200 can be provided with a filter element 210, and the filter element 210 is used to be arranged in the water channel for filtering raw water to provide filtered water.

[0042] The power generation assembly 300 includes a generator 310 disposed in the waterway channel. The generator 310 is configured to generate electrical energy under the action of water in the waterway channel.

[0043] The digital display assembly 400 is used to display the working status of the water purifier 100. The working status includes but is not limited to at least one of the clogging service life of the filter element 210, the service life of the filter element 210, the real-time water temperature, the speed of the generator, and the power level of the built-in battery.

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

[0045] The control unit 410 is used to obtain the initial electrical energy of the generator 310 and the real-time electrical energy of the generator 310 and calculate the clogging service life 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 obtain the total duration of the generator 310 generating electrical energy and calculate the service life of the filter element 210 based on the total duration. The initial electrical energy is the initial electrical 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 electrical energy is the real-time electrical energy generated by the generator 310 detected and obtained during the use of the water purifier 100 after the filter element is replaced.

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

[0047] In the water purifier 100 provided in the present application, the display unit 420 is provided to display the clogging service life of the filter element 210 and / or the long service life of the filter element 210, which can remind the user to replace the filter element in time. In addition, by calculating the two types of the clogging service life and the long service life, the display unit 420 can be controlled to display the lower value of the clogging service life and the long service life, or to display the clogging service life and the long service life at the same time or alternately, thereby not only reminding the user based on one parameter, but also taking into account the degree of clogging of the filter element 210 and the working time of the filter element to remind the user, thereby achieving a more accurate filter element replacement reminder and a better user experience.

[0048] Furthermore, the degree of filter element blockage is calculated based on the initial electrical energy and the displayed real-time electrical energy. The initial electrical energy can be obtained based on factors such as the water pressure of the connected faucet, which can provide a more accurate reference basis and more accurate calculation of the degree of filter element blockage than a method in which the system has its own initial electrical energy set value. It is understood that the initial electrical energy can be the initial electrical energy of the generator 310 that the control unit 410 first obtains when the user opens the faucet connected to the water purifier 100 to the maximum after the filter element is replaced.

[0049] In addition, in the first embodiment of the present application, the generator 310 does not require an external power supply for power supply. The generator 310 is driven by the water flow in the waterway to generate electricity, thereby realizing resource recycling and utilization to generate 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 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.

[0050] The digital display assembly 400 is also used to electrically connect to the generator 310 so as to operate 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 an operating voltage. The control unit 410 is used to receive the operating voltage to operate; 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 voltage conversion circuit 510 can convert the electric energy generated by the generator 310 into the voltage required for the operation of the control unit 410 and the like. 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.

[0051] 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 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.

[0052] Furthermore, the initial electric energy is at least one first signal of the current, real-time voltage, electric energy per unit time (i.e., electricity), frequency, electromotive force, or speed of the alternating current generated by the generator 310 detected by the electric energy detection circuit 24 after the filter element of the water purifier 100 is replaced, and the at least one first signal is used as the initial electric energy; the real-time electric energy is at least one second signal of the current, real-time voltage, electric energy per unit time (i.e., electricity), frequency, electromotive force, or speed of the alternating current generated by the generator 310 detected in real time by the electric energy detection circuit 24 during the use of the water purifier after the filter element is replaced, and the at least one second signal is used as the real-time electric energy. In this application, the electric energy per unit time (i.e., electricity) is mainly used as an example for explanation, but it is not limited to this.

[0053] 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, as shown in Figure 19 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.

[0054] 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. The temperature acquisition circuit 23 is used to collect the real-time water temperature of the water flowing through the water purifier 100 to obtain a water temperature detection signal and smooth the water temperature detection signal and provide it to the control unit 410. The control unit 410 is used to control the display unit 410 to display the real-time water temperature based on the water temperature detection signal.

[0055] Furthermore, the control unit 410 is also used to control the resetting of the blocking service life and / or the duration service life to the initial value when the filter element is replaced next time; the water purifier 100 has a reset member 511, the reset member 511 is electrically connected to the control unit 410, the reset member 511 is used for user operation to generate a reset signal, and the control unit 410 is used to reset the blocking service life and / or the duration service life to the initial value according to the reset signal. It can be understood that through the reset member 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, and the calculation of the degree of blockage of the filter element is more accurate compared to the method in which the system has its own initial electrical energy setting value.

[0056] In a modified embodiment, the water purifier 100 also 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 of the voltage conversion circuit 510 and charge the battery 512. The battery 512 is electrically connected to the control unit 410 and powers 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 LED lights 421 and a light-transmitting cover 422 disposed around the plurality of LED lights 421. The control unit 410 is configured to control the switching of the plurality of LED lights 421 so that the plurality of LED lights 421 display the blockage service life of the filter element 210 or the length of the filter element's service life via the light-transmitting cover 422. The display unit 420 also includes a decorative cover 423 disposed on a side of the light-transmitting cover 422 away from the plurality of LED lights 421. The digital display assembly 400 also includes a main circuit board 430. The control unit 410 and the plurality of LED lights 421 are both disposed on the main circuit board 430. The control unit 410 is located on a surface of the main circuit board 430 away from the plurality of LED lights 421. The LED lights 421 may include a plurality of first LED lights 4211 corresponding to the temperature display area 4221 and a plurality of second LED lights 4212 corresponding to the blockage service life of the filter element or the length of the filter element's service life.

[0058] The water purifier 100 also includes at least one light-emitting element 520, which is arranged at a position near the water outlet 202 of the water channel and is used to emit light toward the water filtered by the filter element 210 to form a decorative effect or to disinfect the water filtered by the filter element 210.

[0063] As shown in Figures 1-2, in this embodiment, the water purifier 100 includes two water outlets 202 and 202', one water outlet 202 is directly connected to the storage chamber 203, and the other water outlet 202' is connected to the water inlet 201 through the switching valve assembly, and the detachment direction of the filter barrel cover 290 or the detachment direction of the filter element 210 is toward the first side 2201.

[0064] Furthermore, as shown in Figures 7 and 8, 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 water outlet 2101, and at least the outer side surface of the filter element body 211 is used to form a water flow channel with the cavity wall of the storage cavity 203, the water flow channel is used to receive the water from the water inlet 201, and the water filtered by the filter element body 211 flows out of the storage cavity 203 through the filter element water outlet 2101; the filter element mounting cover 212 includes a support member 213 and a side wall structure 214 arranged around the periphery of the support member 213, and the side wall structure 214 and the support member 213 surround The filter element mounting cover 212 is provided with a mounting groove 215 for receiving at least a portion of the inner annular wall 226. The inner side surface of the mounting groove 215 is configured to abut and secure against the inner annular wall 226, or the outer side surface of the side wall structure 214 is configured to abut and secure against the inner side of the outer annular wall 227, thereby achieving a removable connection between the filter element 210 and the power generation chamber 225.

The side wall structure 214 has a sealing ring receiving groove 2141, in which the sealing ring 216 is disposed. It can be understood that the design of the filter element mounting cover 212 provides the filter element 210 with a simple structure, stable installation, and convenient assembly and disassembly. The sealing ring 216 not only achieves a watertight seal but also ensures installation stability.

[0065] The control unit 410 may be a control chip, such as an MCU. A data display system may be run inside the control unit 410. As shown in FIG. 21-24 , the data display system may include:

[0066] 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;

[0067] 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 based on the real-time electric energy and the initial electric energy, and display the blockage degree through the digital display component. When the filter element reaches its service life based on the blockage degree, the user is prompted to replace the filter element.

[0068] 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. 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 will not only result in no water purification effect, but will also breed bacteria due to long-term non-replacement of the filter element, affecting the user's water quality.

[0069] Therefore, in this embodiment, a data display system for a water purifier is provided. This system can be used in conjunction with an electric energy detection circuit installed in the water purifier, and the electric energy used by this system is generated by a generator in the water purifier, which is green and environmentally friendly.

[0070] After the filter element of the water purifier is replaced and water flows through the water purifier, this 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 is judged to have reached its service life based on the degree of blockage.

[0071] In a preferred embodiment of the present invention, a power detection circuit is provided in the water purifier and connected to a generator. As shown in FIG21 , the data recording module 1 includes:

[0072] The initial detection unit 11 is used to detect the electric energy generated by the generator in one 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;

[0073] 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 after the filter element is replaced.

[0074] Specifically, as shown in Figures 16-18, in this embodiment, the power detection circuit is provided, and the power detection circuit includes:

[0075] 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;

[0076] A first field effect transistor MOS1 has a collector connected to the other end of the first resistor R1, an emitter connected to one end of the second resistor R2 and grounded, a base 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.

[0077] In a preferred embodiment of the present invention, the life calculation module 2 includes:

[0078] 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;

[0079] 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.

[0080] Specifically, in this embodiment, according to existing electrical technology, we know that electric energy can be calculated according to the following formula:

[0081] W = UIt;

[0082] When a steady water flow passes through the water purifier, the internal generator generates electricity driven by 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 per unit time based on a preset time length (for example, 1s, 2s, etc.);

[0083] When the filter element is used for the first time after it has been replaced, the electric energy generated by the generator in one unit time is calculated as the initial electric energy. During subsequent use, the electric energy generated by the generator in one 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 use 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 final real-time electric energy 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.

[0084] The decimation attenuation method is a method for controller parameter tuning. 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.

[0085] The specific steps of the ten-equal-division attenuation method are as follows:

[0086] 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.

[0087] After reaching stability, add step interference 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.

[0088] Then, according to the formula, the parameter setting value of the controller is calculated.

[0089] In a preferred embodiment of the present invention, as shown in Figures 16-18, a temperature acquisition circuit is further provided in the water purifier, and the data display system further includes:

[0090] 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.

[0091] As shown in Figures 16-18, the temperature acquisition circuit 23 includes:

[0092] 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.

[0093] Specifically, in this embodiment, the system is also provided with a temperature acquisition circuit 23 to detect the temperature of the water flowing through the water purifier;

[0094] In addition, although the detection of water flow parameters such as flow rate and water pressure is not mentioned in this embodiment, in actual situations, this system can be combined with the hardware set in the water purifier, such as displaying the parameters obtained by various detection circuits and various sensors on the digital display component to reflect other parameters about the water flow for users to view.

[0095] In a preferred embodiment of the present invention, a timing circuit connected to a generator 310 is further provided in the water purifier. As shown in FIG21 , the data recording module 1 further includes:

[0096] 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, and to display the duration through the digital display component, and to reset the duration when the filter element is replaced next time.

[0097] In a preferred embodiment of the present invention, as shown in FIG21 , the lifespan calculation module 2 further includes a duration prompting unit 23;

[0098] The time 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 is greater than a preset filter element usage time threshold.

[0099] 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, based on the average household usage of 2 hours per day, a total of 180 hours in 3 months, the filter element service life is calculated using the fuzzy algorithm principle. When the usage time reaches 180 hours, the filter element's service life 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 determined how long the filter element has been used from the time it was replaced to the current moment. When the usage time reaches 180 hours, the filter element's service life ends, prompting the user to replace the filter element. If either the degree of blockage or the usage time is met, it means that the filter element needs to be replaced.

[0100] The present invention further provides a data display method for a water purifier, which is applied to the above-mentioned data display system. As shown in FIG22 , the data display method includes:

[0101] Step S1, after the filter element of the water purifier is replaced and water flows through the water purifier, the data display system detects the initial electric energy generated by the generator, and detects the real-time electric energy generated by the generator during use after the filter element is replaced;

[0102] Step S2: The data display system calculates the blockage degree of the filter element based on the real-time electric energy and the initial electric energy, and displays the blockage degree through the digital display component. It determines whether the filter element has reached its service life based on the blockage degree:

[0103] If so, the user is prompted to replace the filter element;

[0104] If not, return to step S2.

[0105] In a preferred embodiment of the present invention, as shown in FIG23 , step S1 includes:

[0106] Step S11, the data display system detects the electric energy generated by the generator in one 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;

[0107] 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 power detection circuit detects the power generated by the generator in a unit time as the real-time initial power.

[0108] In a preferred embodiment of the present invention, as shown in FIG24 , step S2 includes:

[0109] Step S21: When the data display system detects and obtains real-time electric energy during use of the water purifier after the filter element is replaced, 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;

[0110] Step S22: The data display system determines whether the blockage level is greater than a preset blockage level threshold.

[0111] If so, the user is prompted that the filter element has reached its service life and needs to be replaced;

[0112] If not, return to step S21.

[0113] In a preferred embodiment of the present invention, as shown in Figures 16-18, a temperature acquisition circuit is further provided in the water purifier, and the data display method further includes:

[0114] In 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, performs difference smoothing processing on the real-time water temperature, and then displays it through the digital display component.

[0115] Please refer to Figures 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.

[0116] Please refer to Figures 28 to 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. The generator 710 and the light-emitting element 720 are arranged near the water outlet 702. The electric energy generated by the generator 710 (which can also be 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 setting 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 despite pre-sterilization.

[0117] The above are only preferred embodiments of the present invention and do not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it 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.
