Description

Water purifying device with self-power generation state display system TECHNICAL FIELD

[0001] The present application relates to the field of water treatment, in particular to water purification technology. BACKGROUND

[0002] With the improvement of people's living standards, and the pursuit of drinking water quality, various water purification devices have become daily necessities for people's drinking water. The water purification device is generally equipped with a filter device composed of filter cartridges with different functions. However, after long-term use of the filter cartridge, the filter cartridge will fail and the water quality will deteriorate due to the blockage of the retained material in the filter cartridge and the proliferation of microorganisms. Therefore, during use, the water purification device displays information such as the current water quality and the service life of the filter cartridge, which is very important for people's daily use, and can help people replace the filter cartridge that has reached the end of its life in a timely manner to ensure that the water purification device always provides high-quality drinking water.

[0003] SUMMARY

[0004] The present application aims to provide a water purification device with a self-power generation state display system to solve at least one of the above technical problems.

[0005] The technical problem solved by the present application can be solved by the following technical solution:

[0006] The water purification device with the self-power generation state display system comprises a water purification device, the water purification device having a water outlet channel; further comprising a microprocessor system, the microprocessor system being connected to a display screen; the water outlet channel being connected with a self-power generation device;

[0007] The self-power generation device comprises a shell, the shell having a water inlet and a water outlet, the self-power generation device being connected in series with the water outlet channel through the water inlet and the water outlet;

[0008] The self-power generation device further comprises a power generator and a power storage system, the power generator being electrically connected to the power storage system, and the power output end of the power storage system being connected to the power input end of the microprocessor system;

[0009] The microprocessor system runs a filter cartridge life measurement software;

[0010] One signal input end of the microprocessor system is referred to as a filter cartridge life information input port;

[0011] The filter cartridge life information input port is connected with a sensor system associated with the water outlet quantity of the water outlet channel, referred to as a filter cartridge life sensor;

[0012] The filter cartridge life measurement software calculates the filter cartridge life through the data of the filter cartridge life sensor;

[0013] The self-generating device further comprises a water storage cavity which is connected in series with the water outlet channel through an inlet and an outlet.

[0014] The water storage cavity is arranged above the water inlet of the shell, and the outlet of the water storage cavity is connected with the water inlet of the shell.

[0015] The water inlet of the shell is further provided with a valve device.

[0016] The valve device has a valve body and a rotatable valve plate.

[0017] The valve plate is linked with an elastic reset mechanism which drives the valve plate to reset and close.

[0018] Further comprising a magnet arranged on the valve body and another magnetic component arranged on the valve plate.

[0019] In the closed state of the valve plate, the magnet and the other magnetic component are magnetically coupled.

[0020] In the above design, the self-generating device has a shell, the water inlet is arranged above the shell, and the outlet water vertically enters the shell under the action of gravity to drive the generator rotor to generate electricity.

[0021] The electric energy generated by the power generation device is stored in the power storage system, and the output end of the power storage system is connected with the microprocessor system to supply power to the microprocessor system.

[0022] In the above design, the microprocessor system adopts a micro-power intelligent single-chip microcomputer system, and a software system for measuring the service life of the filter core is run in the microprocessor system. The power generation time or power of the self-generating device is related to the clean water flow through the self-generating device. The power generation time and power are detected and measured by a sensor system associated with the water outlet of the clean water outlet channel, and the detection and measurement data are given to the filter core service life measurement software, so that the filter core service life measurement software calculates the service life of the filter core.

[0023] In the above design, the water flow is accumulated in the water storage cavity through the water storage cavity. When the water flow is accumulated to a certain water level, the water pressure in the water storage cavity breaks the magnetic attraction force between the valve plate and the valve body, releases the accumulated water in the water storage cavity, pushes the water container, drives the rotating shaft to rotate, and then realizes power generation.

[0024] The design adopts a water storage scheme, accumulates water in the water storage cavity, and releases the water when the water volume is sufficient to push the generator rotor to rotate, thereby solving the technical problem that small water volume of clean water is difficult to push the rotor of the generator to rotate and the generator cannot generate electricity, and achieving the effect of small water volume pulse power generation.

[0025] The valve body is arranged on the pipe wall of the water inlet, and the rotatable valve plate is closed in the water inlet pipeline to form a valve device, which has the beneficial effects of simplifying the valve structure and reducing the manufacturing cost of the valve.

[0026] Further, the water inlet is arranged above the shell, and the water outlet is arranged below the shell.

[0027] The shell is provided with a rotating wheel, which comprises a rotating shaft and connecting rods arranged around the rotating shaft, and each connecting rod has a water container with an opening at the end.

[0028] In the rotating track of the water container, there is a position below the water inlet, and in the position below the water inlet, the opening of the water container faces the water inlet.

[0029] The opening area of the water container is matched with the opening area of the water inlet.

[0030] The opening area of the water container is not less than the opening area of the water inlet.

[0031] The rotating shaft is drivingly connected to the rotor of the generator.

[0032] In the above design, the water container has a position below the water inlet in the movement track in the shell, and the opening of the water container at this position faces the water inlet to receive the impact of the clean water flow. The opening area of the water container is matched with the opening area of the water inlet, preferably not less than the opening area of the water inlet. The force of the clean water flow acts on the water container, and the water container is located at the end of the connecting rod. In this design, the length of the force arm from the position of the water container receiving the force to the rotating shaft is relatively long, thereby generating a relatively large torque on the rotating shaft. The beneficial effect is that a relatively small water flow can generate a relatively large torque, thereby improving the power generation efficiency.

[0033] Compared with the conventional impeller, in addition to receiving the force of the clean water flow impact to generate torque to drive the rotating shaft, the water container also has an advantage that the conventional impeller does not have. When the clean water flow is small and the impact force of the clean water flow is not enough to push the water container, the advantage of the water container is that it can accumulate small water flow in the container, and then rely on the gravity of the water accumulated in the water container. The force of the gravity acts on the center of the water container, and the water container is located at the end far away from the rotating shaft, so the force arm is relatively long, and therefore the gravity of the accumulated water is easy to drive the water container to fall, thereby generating a relatively large torque in the water container after accumulating a relatively small water flow, to solve the technical problem of small water flow difficult to generate electricity.

[0034] Further, a trigger circuit is further included as a filter core life sensor, the input end of the trigger circuit is connected to the charging end of the power storage system, and the output end of the trigger circuit is connected to the filter core life information input port of the microprocessor system.

[0035] In the above design, the trigger circuit is a circuit for triggering the filter life metering software in the microprocessor system to time the charging duration. The input end of the trigger circuit is connected to the charging end of the power storage system. When there is a charging current at the charging end, it indicates that there is water flowing in the water purifying device to drive the self-generating device to start generating electricity. Therefore, the charging end is connected to the input end of the trigger circuit. After processing by the trigger circuit, the output start signal is connected to the filter life information input port of the microprocessor system. After the filter life metering software in the microprocessor system reads the data, it starts to accumulate the timing of the charging duration. Therefore, the use duration of the filter can be recorded, and the remaining service life of the filter can be calculated and estimated.

[0036] Further, the water inlet of the shell is provided with a valve device, and the valve device has a rotatable valve plate.

[0037] Further, the water inlet of the shell is provided with a valve device, and the valve device has a rotatable valve plate.

[0038] In the above design, the water inlet of the shell is provided with a valve device, and a micro switch is arranged in the rotatable valve plate. When the rotatable valve plate is in the open state, the micro switch is in the closed state. The micro switch is connected to the filter life information input port of the microprocessor system. Therefore, when the valve plate is opened and the water flows, the micro switch will start the filter life metering software in the microprocessor system to accumulate the timing.

[0039] Further, a power detection device is further included as a filter life sensor. The detection end of the power detection device is connected to the generator.

[0040] The output end of the power detection device is connected to the filter life information input port of the microprocessor system.

[0041] In the above design, the power generation power of the generator is a parameter related to the water flow of the purified water. Therefore, the filter life metering software calls the power generation power data of the generator, which is another method for calculating the remaining service life of the filter.

[0042] Further, the water purifying device has a replaceable filter interface, and the filter interface is provided with a micro switch.

[0043] The microprocessor system includes a reset input port for resetting the filter life metering.

[0044] The micro switch is electrically connected to the reset input port of the microprocessor system.

[0045] In the above design, a micro switch is arranged in the detachable filter core interface. When a new filter core is replaced, the micro switch will be triggered, and the micro switch will send an electrical signal to the reset input port of the microprocessor system. The filter core life metering software running in the microprocessor system reads the signal and clears the accumulated filter core life, thereby restarting the life accumulation of the new filter core.

[0046] Further, the water outlet is also provided with a TDS sensor system connected to the microprocessor system.

[0047] In the above design, the TDS sensor system is used to detect the TDS (total dissolved solids) value of the purified water, and the microprocessor system is connected to the TDS sensor system to read the detected water quality results and display them externally through the display screen.

[0048] Further, the magnet and the other magnetic component are selected to have a magnetic coupling force that meets the following conditions:

[0049] The magnetic coupling force of the matching relationship is selected as:

[0050] The magnetic coupling force is greater than the pressure borne by the valve plate before the water storage cavity is filled with one-half water;

[0051] The magnetic coupling force is less than the pressure borne by the valve plate after the water storage cavity is filled with two-thirds water.

[0052] In the above design, the magnetic attraction force between the rotatable valve plate and the valve body is set to be unable to open the valve plate before the water storage cavity is filled with one-half water; after the water storage cavity is filled with two-thirds water, the valve plate is rotated to open the valve, and the water in the water storage cavity flows into the water inlet to push the water container, thereby driving the rotating shaft to generate electricity.

[0053] The water level of the water storage cavity is controlled to be between one-half and two-thirds, which has the beneficial effect of controlling the volume of the water storage cavity to reduce material usage and manufacturing costs.

[0054] Further, the angle between the water container opening plane and the connecting rod is 15-30 degrees; and the water container is provided with 6-8 water containers.

[0055] In the above design, when the water container receives water flow below the water inlet, the water flow impacts the water container. Due to the angle between the water flow and the water container, the angle causes the force to be decomposed in two directions along the horizontal plane of the water container and the vertical plane. The force decomposed in the vertical plane is smaller, thereby causing smaller torque on the rotating shaft. Therefore, in the present design, the angle between the water container opening plane and the connecting rod is 15-30 degrees. This design can obtain more decomposed force of the vertical force acting on the water container opening plane when the water container receives water flow impact, thereby generating greater torque on the rotating shaft and improving the efficiency of electricity generation.

[0056] In the above design, too many water containers are arranged on the runner, which increases the weight of the runner and wastes the water flow energy, and too few water containers are arranged, which cannot effectively continuously receive the water flow and affects the power generation efficiency.

[0057] Through experiments, it is verified that the optimal number of water containers is 6-8, and 6-8 water containers can smoothly receive the water flow and drive the rotating shaft to rotate.

[0058] Further, the water purifying device is a filter kettle;

[0059] The filter kettle is internally provided with a replaceable filter element;

[0060] A self-power generation state display system is detachably mounted below the filter element;

[0061] The self-power generation state display system comprises a shell, a self-power generation device, a microprocessor system, and a display screen;

[0062] The shell is provided with a water inlet interface detachably connected with a water outlet of the filter element, and the shell is provided with a water outlet interface;

[0063] The shell is internally provided with the self-power generation device, a water inlet of the self-power generation device is communicated with the water inlet interface of the shell, and a water outlet of the self-power generation device is communicated with the water outlet interface of the shell;

[0064] The microprocessor system is connected with the display screen, and the display screen is mounted on the shell;

[0065] The water storage cavity is a filter cavity provided with the filter element, and serves as the water storage cavity;

[0066] A switch for detecting and filtering the connection state of the filter element is arranged in the water inlet interface of the shell, and the switch is electrically connected with a reset input port of the microprocessor system in a state that the shell is separated from the filter element.

[0067] In the above design, the water purifying device is a filter kettle provided with a replaceable filter element, and a self-power generation state display system is connected below the filter element.

[0068] The self-power generation state display system comprises a shell, a water inlet interface is arranged above the shell and detachably connected with a water outlet of the filter element, the shell is internally provided with the self-power generation device, a display screen is arranged on the shell, a microprocessor system is connected with the display screen, and the display screen displays information such as the remaining life of the filter element and the current filtered water quality.

[0069] In the filter kettle, the replaceable filter element is arranged in a filter cavity, and when a valve device of the water inlet is closed, the water to be filtered is accumulated in the filter cavity, thereby forming a water storage effect, so that the filter cavity can serve as a water storage cavity.

[0070] A switch is arranged in the water inlet interface, when the filter cartridge and the water inlet interface are separated, the switch sends an electrical signal to the reset input port of the microprocessor system, and after the filter cartridge life metering software running in the microprocessor system reads the data, the accumulated filter cartridge life is cleared, thereby starting to accumulate the life of the new filter cartridge.

[0071] In the application, the water inlet is arranged above the shell, and the purified water vertically enters the shell under the action of gravity, and impacts the water container below. The opening area of the water container matches the opening area of the water inlet, and the action point of the purified water flow falls in the center of the water container. The water container is located at the end of the connecting rod. In the design, the length of the force arm from the position of the water container bearing force to the shaft is relatively long, thereby generating a larger torque on the shaft. The beneficial effect is that a relatively small water flow can generate a larger torque, and the power generation efficiency can be improved.

[0072] The beneficial effect is that for a purified water device with a small water output, the water storage cavity is used to store water to a certain water level and then release to drive the water container to rotate, which can solve the problem that small water flow cannot generate electricity.

[0073] The beneficial effect is that the timing function is realized by the intelligent system with low power consumption, and the TDS sensor system is connected to realize the real-time display of the filter cartridge use time, TDS index and other state information of the purified water device during use, which is beneficial to people to master the timing of replacing the filter cartridge of the purified water device, to ensure that the purified water device provides high-quality drinking water, and is beneficial to people's health.

[0100] The electric energy generated by the generating device is stored in the power storage system, and the electric output end of the power storage system is connected with the microprocessor system to supply power to the microprocessor system.

[0101] In this embodiment, the microprocessor system adopts a micro-power intelligent single-chip microcomputer system, and a software system for metering the filter core life is run in the microprocessor system, the generating time or the generating power of the self-generating device is related to the clean water flow through the self-generating device, the generating time and the generating power are detected and metered through the sensor system associated with the water output of the clean water outlet channel, and the detection and metering data are given to the filter core life metering software, so that the filter core life metering software calculates the service life of the filter core.

[0102] In this embodiment, the clean water flow is accumulated in the water storage cavity 9. When the clean water flow is accumulated to a certain water level, the water pressure in the water storage cavity 9 breaks the magnetic attraction between the valve plate 6 and the valve body, releases the water accumulated in the water storage cavity 9, pushes the water container 3, drives the rotating shaft 5 to rotate, and then realizes power generation.

[0103] The design adopts a water storage scheme. When the water volume in the water storage cavity 9 is sufficient, the water is released to drive the generator rotor 12 to rotate, thereby solving the technical problem that the rotor 12 of the generator cannot be rotated by the clean water with a small water volume, and the generator cannot generate power. The design has the effect of small water volume pulse power generation.

[0109] The opening area of the water container 3 is not less than the opening area of the water inlet 8.

The beneficial effect is that a relatively small water flow can generate a relatively large torque, and the power generation efficiency is improved.

[0112] In the embodiment, the water container 3 has another advantage than the conventional impeller, which is that when the water flow is small and the impact force of the water flow is insufficient to push the water container 3, the water container 3 can accumulate the small water flow in the container, and then rely on the gravity of the water accumulated in the water container 3, the force of the gravity falls on the center of the water container 3, and the water container 3 is located at the end far from the rotating shaft 5, so the force arm is long, and thus the gravity of the accumulated water is easy to drive the water container 3 to fall, and then a relatively small water flow can be accumulated in the water container 3 to generate a large torque, so as to solve the technical problem that it is difficult to generate electricity with a small water flow.

[0135] The magnetic coupling force is less than the pressure borne by the valve plate 6 after the water storage cavity 9 is filled with two-thirds water.

[0136] In the embodiment, the magnetic attraction force between the rotatable valve plate 6 and the valve body is set to be such that the valve plate 6 is closed and cannot be opened before the water storage cavity 9 is filled with one-half water, and the valve plate 6 is rotated to open the valve after the water storage cavity 9 is filled with two-thirds water, so that the water in the water storage cavity 9 flows into the water inlet 8 to push the water container 3 and drive the rotating shaft 5 to rotate to generate electricity.

[0137] The water level of the water storage cavity 9 is controlled to be between one-half and two-thirds, which has the beneficial effect of controlling the volume of the water storage cavity 9 to reduce the use of materials and lower the manufacturing cost.

[0138] Referring to FIGS. 1 and 5, the angle A between the opening plane of the water container 3 and the connecting rod 2 is 15-30 degrees, and the water container 3 is provided with 6-8 water containers.

[0139] In the embodiment, when the water container 3 receives the water flow below the water inlet 8, the water flow impacts on the water container 3. Due to the existence of the angle A between the water flow and the water container 3, the angle A causes the force to be decomposed in two directions, i.e., the horizontal plane and the vertical plane of the water container 3. The decomposed force in the vertical plane is small, thus causing a small torque on the rotating shaft 5. Therefore, in the design, the angle A between the opening plane of the water container 3 and the connecting rod 2 is 15-30 degrees. Such a design can obtain more decomposed force in the vertical direction of the opening plane of the water container 3 when the water container 3 receives the water flow impact, and thus can generate a greater torque on the rotating shaft 5, which can improve the electricity generation efficiency.

[0140] In the embodiment, too many water containers 3 are provided, which can increase the weight of the rotating wheel and waste the water flow energy, and too few water containers 3 are provided, which cannot effectively continuously receive the water flow and affect the electricity generation efficiency.

[0141] Experiments have verified that the optimal number of the water containers 3 is 6-8, and 6-8 water containers 3 can smoothly receive the water flow and push the rotating shaft 5 to rotate.

[0142] Referring to Fig. 4, the water purifying device is a filter kettle;

[0143] The filter kettle is provided with a replaceable filter cartridge 16;

[0144] A self-power generation state display system is detachably mounted below the filter cartridge 16;

[0145] The self-power generation state display system comprises a housing 15, a self-power generation device, a microprocessor system and a display screen;

[0146] The housing 15 is provided with a water inlet interface 151 detachably connected to the filter water outlet 1411 of the filter cartridge 16, and a water outlet interface 152;

[0147] The self-power generation device is assembled in the housing 15, and the water inlet 8 of the self-power generation device is connected to the water inlet interface 151 of the housing 15, and the water outlet 4 of the self-power generation device is connected to the water outlet interface 152 of the housing 15;

[0148] The microprocessor system is connected to the display screen, and the display screen is mounted on the housing 15;

[0149] The water storage cavity 9 is a filter cavity provided with the filter cartridge 16;

[0150] A switch for detecting the connection state of the filter cartridge 16 is arranged in the water inlet interface 151 of the housing 15, and the switch is electrically connected to the reset input port of the microprocessor system when the housing 15 is separated from the filter cartridge 16.

[0151] In this embodiment, the water purifying device is a filter kettle provided with a replaceable filter cartridge 16, and a self-power generation state display system is connected below the filter cartridge 16.

[0152] The self-power generation state display system comprises a housing 15, a self-power generation device, a microprocessor system and a display screen;

[0153] In the filter kettle, the replaceable filter cartridge 16 is arranged in a filter cavity, and when the valve device of the water inlet 8 is closed, the water to be filtered is accumulated in the filter cavity, thereby forming a water storage effect, so that the filter cavity can play a role of the water storage cavity 9.

[0154] A switch is arranged in the water inlet 151, when the filter element 16 is separated from the water inlet 151, the switch sends an electric signal to the reset input port of the microprocessor system, the filter element life metering software running in the microprocessor system reads the data, and then clears the accumulated filter element life, so as to start the life accumulation metering of the new filter element 16.
